Description

Car rear tooth package disassembly elevator

technical field

The utility model relates to a lifting device, in particular to an automobile rear tooth bag disassembly and assembly elevator used for disassembling and assembling the automobile rear tooth bag.

Background technique

At present, there are various types of elevators for rear teeth packaging of small and medium-sized cars in China, mainly diamond-shaped lifting platforms and forklifts. The diamond-shaped platform has a small lifting force, cannot fix the lifting object, and is easy to roll, which has unsafe factors. However, due to the large size of the forklift machine and the center of gravity of the fork arm, the rear part tends to be upturned when lifting heavy objects, so it is not suitable for lifting large objects in narrow areas. . The rear teeth of the 3307 car weighed 500Kg, and the disassembly and assembly position was relatively narrow. There were tires on the left and right, a gearbox in the front, and a large box in the back. It is time-consuming and laborious to disassemble and assemble the rear gear of 3307 automobiles, which greatly increases the labor intensity of workers and prolongs the repair time of 3307 automobiles. However, there is no manufacturer in the country that produces the 3307 car rear tooth pack disassembly and assembly elevator for mining, which makes it extremely difficult for workers to disassemble and repair the rear tooth pack, and it is difficult to effectively guarantee the worker's work safety.

The marks in the figure are: lifting platform 1, power input end 2 of rear teeth package, arc support seat 3, fixed ring 4, support frame 5, cart 6, auxiliary hydraulic cylinder 7, active hydraulic cylinder 8, hydraulic pipeline 9 , a power driver 10 , and a main body 11 of the posterior tooth pack.

Detailed ways

Below in conjunction with accompanying drawing and embodiment the utility model is further described.

As shown in Fig. 1 and Fig. 2, the lifter for disassembling and assembling car rear teeth of the present utility model includes a lifting platform 1 and a lifting driving device acting on the lifting platform 1. When removing the rear teeth package, the lifting drive device drives the lifting platform 1 to move upward. When the lifting platform 1 moves to the position of the rear teeth package, the lifting platform 1 is used to support the rear teeth package, and remove the rear teeth package from the car. Next; when installing the rear tooth pack, put the rear tooth pack on the lifting platform 1, the lifting drive device lifts the lifting platform 1 to the installation position of the rear tooth pack, and installs the rear tooth pack on the car, thus greatly improving the disassembly and assembly efficiency and reduce the labor intensity of workers.

In order to be more stable during disassembly, one end of the lifting platform 1 is provided with an arc-shaped support seat 3 for supporting the main body 11 of the posterior dental kit, and the other end is provided with a fixed ring 4 for fitting the power input end 2 of the posterior dental kit. Then, when dismounting or installing the arc-shaped support seat 3, the back tooth bag main body 11 is supported on the arc-shaped support seat 3, and the back tooth bag power input end 2 is sleeved in the fixed ring 4, which can prevent the back tooth bag from falling off during the lifting process. Rolling down on the lifting platform 1 makes the rear teeth package lift up and down smoothly on the lifting platform 1, improving the safety of workers during operation.

In the above embodiment, the fixed ring 4 can be integral, but when it is disassembled and installed, the power input end 2 of the posterior dental bag can only be inserted into the fixed ring 4 from one side of the fixed ring 4, so that the posterior dental bag can enter into the In the fixed ring 4 , two semicircular fixed rings are detachably connected to form the fixed ring 4 . Then when dismounting or installing the back tooth pack, the upper half circle of the fixed ring 4 can be disassembled earlier. In this way, only the lower half of the fixed ring 4 is left on the lifting platform 1, and the lifting platform 1 can directly move up and down vertically and in the direction of the dental package axis, and can quickly install the rear dental package power input end 2 into the fixed ring In the lower half circle of 4, avoiding the need to insert the power input end 2 of the rear tooth pack into the fixed circle 4 during disassembly and installation can greatly improve the efficiency of disassembly and installation.

In the above embodiments, the lifting drive device for driving the lifting platform 1 to move up and down may adopt a four-bar mechanism, a rack and pinion transmission mechanism, a chain transmission mechanism and the like. As a preferred mode, the lifting drive device acting on the lifting platform 1 includes at least three support frames 5 and carts 6, one end of the support frame 5 is hinged on the lower surface of the lifting platform 1, and the other end is hinged on the cart 6 , the cart 6 is provided with an auxiliary hydraulic cylinder 7 connected in series through a hydraulic pipeline 9 and an active hydraulic cylinder 8 to form a hydraulic control system, the piston rod of the active hydraulic cylinder 8 is hinged to the support frame 5, and the piston rod of the auxiliary hydraulic cylinder 7 A power driver 10 is arranged on it. When working, the power driver 10 pulls the piston rod of the auxiliary hydraulic cylinder 7 to move in the chamber of the auxiliary hydraulic cylinder 7, and pumps the hydraulic oil to the active hydraulic cylinder 8 through the hydraulic pipeline 9, so that the active hydraulic cylinder 8 and the support The frame 5 rotates to lift the lifting platform 1 to realize the lifting action; when the lifting platform 1 is lowered, it is only necessary to remove the hydraulic oil in the active hydraulic cylinder 8. Its working principle is the same as that of hydraulic forklifts commonly used in factories. The principle is the same, and will not be repeated here. The setting of at least three support frames 5 can make the support frame 5 form a support plane, realize the smooth lifting of the lifting platform 1, and the trolley 6 can facilitate the transportation of the straight posterior dental package when the posterior dental package is disassembled or installed, and No other transport equipment is required.

In the above embodiment, the power driver 10 may drive the auxiliary hydraulic cylinder 7 to work in an electric manner. In order to reduce costs, the power driver 10 uses a manual rocker. The auxiliary hydraulic cylinder 7 can be operated by shaking the manual rocker up and down, and the lifting platform 1 can be lifted. The structure is simple, the action is reliable, and the control of the lifting distance of the lifting platform 1 is also convenient.
