In the construction machinery work, the scene environment is often not good, for example, in the construction of the project, due to the construction of more places in remote areas, combined with the tight construction funding, the variety of machinery and equipment and the type of miscellaneous, so once damaged machinery and equipment , Often due to the lack of individual components and affect the use of machinery and construction period; in motor vehicle maintenance, motor vehicles suddenly fail, sometimes can not buy standard accessories. Therefore, we should be able to flexibly handle some problems that may appear tricky in the use and maintenance of construction machinery, so that we can often receive a multiplier effect. For example, emergency supplies can be obtained from some readily available daily necessities and can receive better results. Effect. Here, this article describes several simple and easy emergency repair methods. First, the parts can not work properly and the site how to solve 1. Parts installation errors For example, some construction machinery hydraulic cylinder seals in the ring (mainly made of PTFE filled with flexible material) less flexible, so Before installation, it should be soaked in oil at 100oC for 10 to 20 minutes to soften it, then install it by its elasticity. 2. Parts operation problems This problem caused more, especially when the operation of construction vehicles, the new driver is not familiar with the performance of the machine. For example, the spline of a semi-axle of a construction vehicle often wears away. Later on, it was found that the driver did not disengage the differential lock. As a result, the load on the transmission part was increased and serious wear was caused. Therefore, the operation was improved. 3. Parts related parts damage caused damage For example, an excavator two walking hydraulic motor at the same time broken, after inspection, is the multi-turn joint oil seal damage caused by plugging the loop, so to promptly solve this Problem, otherwise the hydraulic motor will be damaged in the future. 4 parts quality problems, such as a Taiwan excavator, the hydraulic motor, hydraulic pump, reducer bearings are damaged, the replacement of the original bearings or bad, the last installation of imported bearings to solve the problem. Similarly, this excavator boom cylinder oil seal is also often damaged in the summer, and later found to be the original piston and cylinder with the gap too much. Re-processing the scene after the piston, the seal will not be broken. Second, several emergency repair skills 1, clever use of wrench to bolt sometimes due to the lack of suitable wrench lead to disassembly parts difficult, especially the import of some engineering machinery bolts, disassembly with domestic wrench non-large or small. In addition, sometimes due to the wrench is not complete, disassembly will have problems. In this case, the following solutions can solve the pressing problem (mainly for plum wrenches, open-end wrenches (wrenches) and hex wrenches, the use of wrenches and pipe wrenches and other tools as little as possible, or easily damaged parts), if used The plum or open end wrench is larger than the bolt head (or nut) to be screwed in. The Allen wrench is smaller than the bolt head to be screwed in. Some copper pads may be padded inside the wrench (plum, open end wrench) or wrench (inside hex wrench) Wire or Screwdriver and other objects, and then slowly plus force disassembly, loading; and when the open-end wrench than the bolt head (or nut), hex wrench than the bolt head, respectively, Hexagonal wrench hexagonal file size small. Through the above treatment can solve the majority of emergency demolition, loading work, and the restructuring of the wrench can be reserved for later use. 2. Qiaopu bearing ring W4 a 60 excavator pump (SKI a 82 type) connecting rod bearing is often damaged, the bearing outer ring is still damaged in the link hole is difficult to remove because of hard outer ring Easy to slip when the hacksaw saw, hard and hard hard knock and easy to make connecting rod damage. At this time, the connecting rod can be clamped on the vise, the use of heavy-duty socket wrench in the hedging, one side of the outer ring than the bearing sleeve slightly smaller thrust bearing outer ring, the other side with a smaller than the connecting rod bearing hole size A large hedging to withstand the side of the connecting rod hole, and then gradually force clamp vise, so the bearing outer ring will be slowly pressed out. If gas cutting tools, you can cut directly with gas cutting bearing outer ring. 3. Cleaving Tires When removing large wheel loaders, bulldozers tires, the separation of tires and rims is a more difficult task, due to prolonged use without demolition, the rim may rust, the tire and rim sticky very tight. The use of deflated, back and forth walking RCC method of demolition, the effect is not very satisfactory, and can achieve the following results with better results: After removing the lock ring (some imported construction machinery such as WD140 bulldozer equipped with a tire Ring) between the tire and the rim to add water for lubrication, with two bulldozers blade pressure on both sides of the tire, the middle of a suitable length with a suitable iron bar across the wheel 惘, and then put on the rope with a crane or loader, etc. Lifting, so that the tire and the rim is very easy to separate. 4. Clearance for the sale of W4 a 60C excavator pin shaft pin set due to prolonged use, the lack of lubrication and damage, replacement, if not pay attention to the method, often make the pin set installation is not in place, causing the end damage. In this regard, the pin sleeve can be set on the corresponding pin, and then the pin through the pin seat hole alignment, and then use hand hammer to hammer the pin end, the pin head pin pin into the pin Sleeve hole. This method does not damage the pin sets, does not produce skew, simple and reliable. Third, the use of daily necessities emergency substitutes Daily necessities emergency substitutes is not a timely emergency measures must proceed from reality: First, to be simple and easy, short production time; second is to ensure traffic safety; third is to not damage the original A device that does not cause damage to other parts; Fourth, after an emergency, the timely replacement of regular parts. 1. Use bicycle parts emergency 1.1 If the diesel engine ejector pinhole small ball missing, you can use the bike flywheel ball instead, you can also use the scrap beads instead of small steel ball mouth. 1.2 When the agricultural truck clutch release bearing return spring break, you can use the bicycle seat stretch spring alternative. 1.3 Dongfeng a 12-type tractor on the fixed steering fork and steering arm pins if worn, you can use bicycle crank pin instead. 1.4 In the tire filling, deflation, often need to screw out the valve core, sometimes due to improper use, or after long-term use of the lower part of the valve core thread broken in the valve, and more difficult to remove the broken head.
