Description

Technical Field

[0001] The utility model belongs to the technical field of tooling lifting tools, and in particular relates to an auxiliary lifting device for a forklift. Background Art

[0002] A forklift crane is a lifting device installed at the front end of a forklift, which can be used to move the cargo on the lifting device.

[0003] At present, the Chinese utility model with the publication number of CN220642466U discloses a new type of cargo lifting device for forklift, including: a base, used to connect with the fork of the forklift; a boom, rotatably connected with the base; a connecting rope, connected between the boom and the door frame of the forklift; a winding shaft, rotatably mounted on the base, with a lifting rope wound on the winding shaft, and the lifting rope passes around the end of the boom away from the base; a driving assembly, including a worm wheel and a worm, the worm wheel is fixedly connected with the winding shaft, and the worm is meshed with the worm wheel. The cargo lifting device can carry out cargo lifting operations by setting a boom, and then using the cooperation of the boom and the forklift, wherein the setting of the boom can increase the lifting height of the cargo to a certain extent, and the boom extends out of the end of the fork away from the forklift, so the design of the cargo lifting device effectively improves the applicability of forklift cargo lifting.

[0004] The existing forklift crane cannot automatically unhook the sling from the cargo after hoisting the cargo, and often needs to be unhooked manually. This operation mode poses a great safety hazard to the workers. In addition, when the forklift crane is installed on the forklift, it is generally fixed with bolts, and the spacing between the fork teeth of different forklifts is also inconsistent. Therefore, it is difficult to quickly install the forklift crane on forklifts with different fork teeth, which reduces the installation efficiency and is inconvenient for actual use. For this reason, we propose an auxiliary lifting device for forklifts. Utility Model Content

[0005] The utility model aims to provide an auxiliary lifting device for a forklift, which has the advantages of being easy to quickly install a forklift sling on a forklift with fork teeth of different spacings and being able to automatically unhook the forklift sling from the cargo.

[0007] By adopting the above technical solution, the first motor is turned on to drive the winding wheel to rotate and the pull rope is rolled up, so that the pull rope pulls the hook to rotate upward at the bottom of the connecting plate, thereby causing the cargo to slide off the hook, thereby automatically unhooking the forklift sling from the cargo, which is convenient for actual operation; the fork tine of the forklift is inserted into the fork tine groove, so that the fork tine can directly drive the sling to move, and at the same time, the bidirectional screw is rotated to engage with the threaded sleeves on both sides, so that the two plug plates are respectively driven to adjust according to the spacing of the fork tine of the forklift, thereby facilitating the rapid installation of the forklift sling to forklifts with fork tine of different spacings, thereby improving practicality.

[0008] The utility model is further configured as follows: a bidirectional screw is rotatably connected inside the base, plug plates are slidably connected on both sides of the bottom of the base, threaded sleeves are threadedly sleeved on both sides of the surface of the bidirectional screw and fixedly connected to two plug plates respectively, and a fork tooth groove is opened inside the plug plate.

[0009] By adopting the above technical solution, the fork tines of the forklift are inserted into the fork tine grooves, so that the fork tines can directly drive the spreader to move. At the same time, the two plug plates can also be adjusted according to the spacing of the fork tines of the forklift, so as to facilitate the rapid installation of the forklift spreader to forklifts with fork tines of different spacings, thereby improving practicality.

[0010] The utility model is further configured as follows: a second motor is installed on one side of the top of the base, and an output end of the second motor is fixedly connected to one side of the rotating block.

[0011] By adopting the above technical solution, the hydraulic rod and the extension rod can be driven to rotate on the top of the base by turning on the second motor, so that the goods can be easily lifted upwards.

[0012] The utility model is further configured as follows: one side of the top and the bottom of the surface of the hydraulic rod is fixedly connected with a hydraulic oil conduit used in conjunction with the extension rod.

[0013] By adopting the above technical solution, hydraulic oil is injected into the hydraulic rod through the hydraulic oil conduit, thereby controlling the extension rod to perform telescopic activities inside the hydraulic rod, so that the sling can lift goods at a farther location.

[0014] The utility model is further configured as follows: a sliding groove is provided at the bottom of the hook.

[0015] The above technical solution is adopted to reduce friction and facilitate the goods to slide out of the interior of the hook.

[0016] The utility model is further configured as follows: rollers are fixedly mounted on both sides of the bottom of the plug board.

[0017] The adoption of the technical solution makes it easy to push the forklift crane to move, thereby facilitating the installation of the forklift.

[0018] The utility model is further configured as follows: both sides of the top of the plug plate are threadedly connected with fastening bolts.

[0019] By adopting the above technical solution, the forklift crane is fixed to the forklift by tightening the fastening bolts, thereby improving the stability of the forklift crane installed on the forklift.

[0020] The utility model is further configured as follows: one end of the bidirectional screw rod passes through the interior of the base and is fixedly connected to a rotating disk.

[0021] The adoption of the technical solution facilitates the rotation to drive the bidirectional screw to rotate.

[0022] In summary, the utility model has the following beneficial effects:

[0023] 1. The first motor is turned on to drive the reel to rotate and reel up the draw rope, so that the draw rope pulls the hook to rotate upward at the bottom of the connecting plate, thereby making the cargo slide off the hook, thereby automatically unhooking the forklift sling from the cargo, which is convenient for actual operation;

[0024] 2. By inserting the fork tine of the forklift into the fork tine groove, the fork tine can directly drive the spreader to move, and at the same time, the bidirectional screw is rotated to engage with the threaded sleeves on both sides, so that the two plug plates are respectively driven to adjust according to the spacing of the fork tine of the forklift, thereby facilitating the rapid installation of the forklift spreader to forklifts with fork tine of different spacings, thereby improving practicality.
