The NTE260 mining dump truck carriage is used as a part for loading materials and directly bears impact and abrasion from the loading of the materials. The flat and wide platform floor and the relatively low loading height can not only reduce the gravity height of the whole vehicle, but also improve the loading efficiency. Wider cars are cumbersome to remove for repair. The carriage is connected with the rear tailstock of the frame through a hinge pin shaft and is in contact with the longitudinal beam of the frame through a carriage cushion pad below the longitudinal beam. Preparation work needs to be done before the carriage is disassembled, and the operation is strictly carried out according to steps on the premise of ensuring safety.
The method comprises the following specific steps:
(1) Verifying that the lift cylinder is fully retracted and secured near the installation location.
(2) The structure of the carriage conforms to the requirements of the mine car, and the repair preparation work is completed.
(3) The carriage hoisting hole is connected by using a proper hanger, the carriage is slowly hoisted, and the front part of the carriage is higher than the rear part.
(4) The car was hoisted completely off the frame and stopped about 10cm above the frame.
(5) The NTE260 manipulator slowly drives the dumper out under the guidance of a commander and leaves the hoisting position.
(6) The carriage is slowly dropped to the ground and is leveled.
(II) detaching wheel motor
(1) The special rings are respectively arranged at two ends of the wheel motor, and the hoisting points are kept at the coaxial position and cannot deviate.
(2) And (3) taking the 50t truck crane in place, keeping the hoisting radius in a range capable of hoisting a heavy object above 14t, hoisting the rod to tighten the hoisting rope to suspend the wheel motor under stress, and then starting to release the fixing bolt between the wheel motor and the frame.
(3) Hoisting wheel motor: the wheel motor is slowly translated out of the rear axle under the direction of the jackman and then dropped onto a fixed platform.
(4) And releasing the hoisting rope and the hoisting tool, and finishing the hoisting work of the wheel motor.
The conventional wheel motor dismounting steps are enough for explaining the defects of complicated hoisting process and high hoisting difficulty coefficient in the prior art.
Therefore, the problem needs to be solved by developing a tool for disassembling and assembling the bow of the electric wheel motor of the mining dump truck.

A relatively large operation space exists between the carriage and the wheel motor, and if the wheel motor is directly suspended and translated below the carriage through a special hoisting tool, the purpose of disassembling and assembling the wheel motor can also be achieved. The bow-shaped tool can bypass the carriage and directly act on the wheel motor through gravity center transmission so as to realize hoisting operation.
Selecting tool hoisting parameters:
(1) The vertical distance between the top of the wheel motor and the bottom of the carriage is 225cm;
(2) The horizontal distance between the wheel motor and the frame is 310cm;
(3) The height of the lifting position of the carriage is 280cm;
(4) The total weight of the wheel motor is 14.5t;
(5) The wheel motor center of gravity is determined.
Manufacturing a tool:
manufacturing parameters of bow-shaped tool
According to relevant measured data, the arch-shaped tool meeting the hoisting size is manufactured, the length of the upper beam is 2.5 meters, the length of the vertical beam is 4 meters, the length of the lower beam is 3.5 meters, and the length of the first upper lifting lug extending out of the upper beam and the length of the first lower lifting lug extending out of the lower beam are both 0.275 meters.
Arch-shaped tool making material
The tool material is 10m of seamless steel pipe with the diameter of 600mm and the thickness of 25mm and 0.5m of steel plate with the thickness of 45mm 2 Then, the seamless steel tube is processed and cut into 1 steel tube with 4m length, 1 steel tube with 3.5m length and 1 steel tube with 2.5m length by a plasma cutting machine. In order to increase welding strength and improve hoisting safety, the steel pipes are respectively chamfered by 45 degrees. The steel plate is processed into a semicircular hoisting point with an outer diameter of 275mm and an inner hole of 70mm by a plasma cutting machine, and the steel plate with the thickness of 45mm is processed into 2 rectangular sections with the size of 550mm multiplied by 950mm and 4 triangular sections with the size of 400mm multiplied by 400mm by using the plasma cutting machine to be used as a reinforcing rib plate for connecting steel pipes. And after the material preparation is finished, starting tooling manufacture.
(III) welding of tools
Firstly, a square steel plate is inserted into a chamfered steel pipe for welding, the welding requires the steel plate to be consistent with the center of the steel pipe, and the two sides of the steel pipe are welded. And after welding, the quality needs to be checked through penetration inspection. And after the welding of the internal reinforcing rib plate is finished, the chamfered steel pipe is butt-welded. And after the welding of the outer part of the steel pipe is finished, welding a reinforcing plate at the right angle for supporting. And (4) after welding, checking the welded workpiece by using a level gauge, confirming that no obvious distortion exists, and considering the welded workpiece for use after the tool is manufactured and detected to be qualified.
Hoisting test and formal hoisting:
hoisting test
After the wheel motor assembly is rightly arranged in a hoisting test area, the wheel motor is hoisted through a 50t automobile, 8.5t hand hoists are respectively hung at the bottom of the tool, and hoist hoisting points are sequentially hung on the two sides and the middle of the wheel motor. And guide ropes are arranged at two ends of the wheel motor, and the length of the guide ropes is not less than 10m. After the inspection is correct, the crane manipulator slowly starts to hoist under the command of the crane worker. The wheel motor is hung on the ground about 10cm away from the ground, the rear part is suspended stably for 2min, and after no safety risk is determined, a repairman enters a hoisting area to adjust each manual hoist hoisting point. And finally, keeping the wheel motor in a horizontal position, and finishing the hoisting test. After the test is finished, collecting hoisting parameters and data of the adjusting rope of the hand-operated hoist in the hoisting process, and preparing for formal hoisting.
(II) formal hoisting
The 50t truck crane is parked at the tail part of the NTE260 carriage and is arranged in parallel with the wheel motor, and the parallel distance is kept at about 5 m. After the tool bypasses the carriage, the center of a lifting point below the tool is positioned at the center of the wheel motor by adjusting the large arm of the crane, the rope of the crane is tightened after the tool is hung, and then a repairer starts to loosen the fixing bolts around the wheel motor. Because the weight of the wheel motor and the tool reaches 17t, a crane operator is required to suspend in advance before the bolt is completely removed, the hoisting weight is kept at 17t, and the wheel motor is prevented from shaking due to the fact that the difference of the hoisting weight is too large. In the process of moving out the wheel motor, the wheel motor is stably moved out to a position about 2m away from the edge of the carriage by synchronously controlling the guide rope when the hoisting center of the crane moves. Under the command of a crane worker, a crane manipulator slowly puts the wheel motor to the fixed platform horizontally, and the hoisting is finished.
The electric wheel motor of the NTE260 dumper is disassembled and assembled by the aid of the arch-shaped tool, operation is simple and convenient, trouble of disassembling a carriage is avoided, hoisting safety risks are greatly reduced, repair time is shortened, and cost reduction and efficiency improvement effects are obvious.
The foregoing is only a preferred embodiment of the present invention, and it should be noted that, for those skilled in the art, a plurality of improvements and decorations can be made without departing from the technical principle of the present invention, and these improvements and decorations should also be regarded as the protection scope of the present invention.
