Description

Arbitrary automatic telescopic supporting tool for assembling large-tonnage dump truck

Technical Field

The utility model relates to a strutting arrangement especially relates to a large equipment assembly is with location and be convenient for device that removes, belongs to mechanical positioning frock technical field.

Background

With the rapid development of heavy industry, lean production, 6s management, green manufacturing and the like are increasingly emphasized, so that the production assembly environment, the working efficiency and the working strength of a workshop are required to be substantially improved, and the problem that a matched tool needs to be modified and upgraded is solved. For example, a hundred-ton vehicle assembly workshop is responsible for assembling 108-ton, 220-ton, 300-ton and other types of dump trucks, and in the assembly process, a dump truck frame is positioned on a tool support seat and suspended in the air, and then a unit type centralized production mode of components such as an oil tank, a cab, an engine, an electric wheel, a hydraulic oil pipe and the like is additionally arranged. The supporting seat for supporting the frame in the workshop belongs to a non-movable supporting tool and is heavy about 100kg, a worker can only be lifted by a crane or pried by a crowbar, and the lifting and positioning of the crane cause the defects of complex operation, personnel cooperation, increased operation risk coefficient, crane resource waste, collision risk on the ground and the like; the prying positioning of the crowbar has the defects of high labor intensity, serious ground damage, serious waste of human resources and the like. In order to meet the requirements of modern new assembly workshops which are about to be put into use, the supporting seat which is small in labor intensity, accurate in positioning, free of damage to the field environment, capable of being fixed and fixed during assembly and convenient to move during no-load is urgently needed.

SUMMERY OF THE UTILITY MODEL

The to-be-solved technical problem of the utility model is to provide a hundred tons of cars assembly can be fixed when with the location operation, the supporting seat of being convenient for remove during empty load to can reduce working strength, improve production efficiency, reduce and destroy ground environment, effective protection production environment saves factory building maintenance cost, and the automatic flexible arbitrary support frock to removing that improves production security.

In order to achieve the above object, the present invention provides a technical solution for solving the technical problem: an arbitrary-direction automatic telescopic supporting tool for assembling a large-tonnage dumper is provided with an adjusting device, a moving device and a supporting device, wherein the adjusting device is used for adjusting the magnitude of a compression force according to dumper types with different weights; the moving device is used for moving the supporting tool; the supporting device belongs to a framework supporting part; three devices are specifically illustrated below:

the bottom plate 1, the support body 2, the spring gasket 7 and the spring 9 form a telescopic mechanism.

The worm shaft 6 and the worm wheel shaft 8 are meshed through a gear and perform matching action; the spiral groove 10 is arranged in the middle of the support body 2, and the worm wheel shaft 8 is in threaded fit with the spiral groove 10; the spring washer 7 is welded to the spring 9 and contacts the worm gear shaft 8. The worm shaft 6 rotates to drive the worm wheel shaft 8 to rotate, the worm wheel shaft 8 is matched with the spiral groove 10 and moves up and down relatively when rotating, and the rising or falling motion of the worm wheel shaft 8 drives the spring 9 to stretch and contract so as to reduce or increase elastic potential energy.

The ball 5 can cooperate and can realize the roll of arbitrary intention between ball wheel body frame 4 and the ball limiting plate 12, and the ball 5 is installed in the middle of the ball wheel body frame 4, is connected with fixing nut 11 by fixing bolt between ball wheel body frame 4 and the ball limiting plate 12.

The handle 3 is rotated to adjust the spring force of the spring 9. The pressure born by the telescopic mechanism can be determined by adjusting the spring force, the pressure directly influences the stress condition and the moving condition of the moving mechanism of the bearing device, and the spring force needs to be adjusted properly.

Detailed Description

The present invention will be described in detail below with reference to the accompanying drawings and examples.

The utility model provides an arbitrary flexible strutting arrangement that is to, includes bottom plate 1, supporter 2, twist grip 3, ball wheel body frame 4, ball 5, worm shaft 6, spring shim 7, worm-gear shaft 8, spring 9, helicla flute 10, fixing bolt and fixation nut 11, ball limiting plate 12, telescope tube 14 and support column 15.

The four stopping mechanisms supporting the upper layer play a positioning role, namely the movement amplitude of the sliding sleeve is determined, so that the height of the automatic telescopic arbitrary moving bearing device away from the ground when no load exists is determined; the expansion amount of the stop mechanism is increased when the stop mechanism is adjusted upwards, and the expansion amount of the stop mechanism is decreased when the stop mechanism is adjusted downwards; the size of the stretching amount is determined according to the ground condition, the stretching amount can be smaller when the ground condition is better, and the stretching amount can be larger when the ground condition is poorer.

The telescopic mechanism can realize automatic telescopic, when the bearing device is acted by a certain heavy object or other pressure, the bearing device can be contacted with the ground to support all loads, the ball wheel is protected from being damaged, after the loads are cancelled, the bearing device automatically leaves the ground, and the ball wheel automatically extends out, so that the bearing device is convenient to move and align.

The ball wheel can move in any direction, and the movement in any direction is very important in alignment and small-range movement of the bearing device and is necessary for working of tools, jacks, supports, special tools and the like.

And the static and dynamic conversion function is that when a heavy object is placed on the support body, the lower surface of the support body generates pressure on the spring gasket, the spring gasket pushes the spring to compress until the support column is in contact with the ground to transmit the pressure to the ground, and the pressure is transferred from the ball wheel to the support column. The strong static friction force generated by the interaction of the supporting column and the ground makes the tool fixed and cannot move easily.

When the heavy object is taken away, the compressed spring still extends, the spring transmits elasticity to the two ends, the upper gaskets jack up the supporting body, the supporting column is lifted off the ground, the pressure is supported and transferred to the ball wheel again, and the tool achieves the function of moving in any direction.

The sensitivity adjustment function is that the rocking handle is rotated to drive the worm shaft to rotate, the worm gear between the worm shaft and the worm wheel shaft is matched to drive the worm wheel shaft to rotate, and the thread on the worm wheel shaft is matched with the thread hole in the support body in a thread way to move up and down when the worm wheel shaft rotates. When the worm wheel moves downwards, force is transmitted to the spring through the gasket, the spring is continuously compressed to enable the spring to have larger elastic potential energy, and the supporting column needs to bear larger pressure when descending for the same distance, so that the sensitivity of the tool is reduced, and otherwise, the sensitivity can be increased.

The utility model discloses the adaptation bears the very big article of weight, and the gravity of article is far more than the automatic flexible arbitrary spring force that removes the expanding spring who bears the device promptly.
