Description

Technical Field

[0001] This utility model relates to a hoisting device, specifically a balance shaft hoisting device. Background Technology

[0002] The balance shaft assembly is one of the core components of a truck suspension system, especially crucial in multi-axle drive (such as 6×4 and 8×4) heavy trucks. The balance shaft assembly uses a lever principle similar to a "seesaw" to evenly distribute the vertical load transmitted by the frame to the middle and rear axles, avoiding overloading of a single axle.

[0003] like Figure 5 As shown, most balance shaft assemblies 21 currently consist of a shaft body 22 and two supports 23. The larger end of the support 23 is flat and is used to connect to the truck chassis by bolts. Therefore, when placing the balance shaft assembly 21, the flat side of the support 23 is usually placed upside down on the ground or on a wooden block. However, due to the large weight of the balance shaft assembly, manual handling is laborious during installation, and the balance shaft assembly needs to be flipped over, which is very inconvenient. Therefore, we propose a balance shaft lifting device. Utility Model Content

Detailed Implementation

[0019] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0020] Please see Figures 1-5 In this embodiment of the present invention, a balance shaft hoisting device includes a base 1, with multiple casters 2 mounted on the bottom of the base 1. An L-shaped bracket 3 is rotatably mounted on the top of the base 1, and a hoist 4 is mounted on the L-shaped bracket 3. Two shackles 5 are suspended from the hoist 4. Two lifting mechanisms 7 are mounted on the top of the base 1 along its length. Each lifting mechanism 7 includes a sleeve 8 fixedly mounted on the top of the base 1, with a slidable tube passing through the opening at the top of the sleeve 8. A screw 9 is installed, and a nut 12 is fitted onto the outer wall of the screw 9 above the sleeve 8. Multiple levers 13 are fixedly connected to the outer wall of the nut 12. A U-shaped seat 14 is fixedly connected to the top of the screw 9. The U-shaped seat 14 is adapted to the shaft 22 of the balance shaft assembly 21. Two internally threaded tubes 15 are fixedly installed on the top of the base 1. A stop bar 16 is installed inside the internally threaded tube 15, and the bottom end of the stop bar 16 is provided with an external thread adapted to the internally threaded tube 15.

[0021] By adopting the above-described solution, in use, after moving the base 1 to one side of the balance shaft assembly 21 via the caster 2, the L-shaped bracket 3 is rotated on the base 1 to move the hoist 4 directly above the balance shaft assembly 21. Then, the shackle 5 is installed at the through hole on the support 23, allowing the balance shaft assembly 21 to be lifted. The two ends of the shaft 22 are then placed on the corresponding U-shaped seats 14. Subsequently, the hoist 4 is used to rotate the balance shaft assembly 21 on the two U-shaped seats 14, causing the support 23 to... After the plane of 3 is facing upward, install the stop bar 16 on the two internal threaded pipes 15 to limit the balance shaft assembly 21 on the base 1 so that the balance shaft assembly 21 can no longer be rotated. Then rotate the hoist 4 to the outside of the base 1 and move the base 1 by the caster 2 to move the balance shaft assembly 21 to the bottom of the truck chassis. Then turn the nut 12 on the two screws 9 to lift the balance shaft assembly 21 to the required height. The balance shaft assembly 21 can then be installed on the truck chassis relatively easily.

One end of the guide pin 11 is located in the corresponding guide groove 10, and the nut 12 is rotatably installed at the top end of the sleeve 8 through a bearing.

[0023] The guide groove 10 and guide pin 11 work together to guide the screw 9 on the sleeve 8, so as to prevent the screw 9 from rotating with the nut 12 during the rotation of the nut 12.

[0024] Specific combination Figure 3 In one embodiment of the present invention, grooves 17 are provided on both outer walls of the base 1, and the lifting mechanism 7 is located between the two grooves 17.

[0025] By setting the groove 17, before lifting the balance shaft assembly 21, the movable base 1 can be positioned in the groove 17, making it easier to use the hoist 4 to lift the balance shaft assembly 21.

[0026] Specific combination Figure 2 and Figure 3 In one embodiment of the present invention, a plurality of guide rods 19 are provided on the top of the base 1, and a counterweight 20 is sleeved on the outer wall of the guide rod 19. Threaded holes 18 are provided at the top of the base 1 and at the corresponding positions of the guide rods 19, and the bottom end of the guide rods 19 is provided with an external thread that matches the threaded hole 18.

[0027] By setting the counterweight 20, after the hoist 4 is rotated to the outside of the base 1, the device can be prevented from tipping over due to the center of gravity shifting to the outside of the base 1, making it safer to use.

[0028] Specific combination Figure 1 In one embodiment of this utility model, a handle 6 is fixedly installed on the outer wall of the L-shaped bracket 3, so as to facilitate the rotation operation of the L-shaped bracket 3.
