Hydraulic forklift truck wheel limiting device

Abstract

This utility model discloses a hydraulic forklift driving wheel limiting device, relating to the field of braking structure technology. It includes a connecting part and a pair of limiting platforms. Both limiting platforms are fixedly installed to the connecting part and are located on the front and rear sides of the forklift's driving wheel, respectively, restricting the driving wheel from rolling forward or backward. The side of the limiting platform facing the driving wheel has an upward slope that increases in height away from the driving wheel. The pair of limiting platforms of this utility model are in contact with the outer edge of the forklift's driving wheel, forming an upward slope. While using its own structure to prevent the driving wheel from rolling forward or backward, it also uses the forklift's gravity to limit the driving wheel's climbing, further improving the limiting effect of the device. It can stably and effectively achieve parking brake limiting of the driving wheel. The device has a simple structure, occupies little space, is easy to manufacture and maintain, and is convenient to install and use. It is suitable for parking brake limiting of driving wheels of various types of forklifts and has good practicality.

Description

Technical Field

[0001] This utility model relates to the field of braking structure technology, specifically to a limiting device for restricting the movement of forklift wheels. Background Technology

[0002] Hydraulic forklifts are a type of handling vehicle widely used in industrial production, capable of loading, unloading, stacking, and short-distance transportation of palletized goods.

[0003] Because hydraulic forklifts typically have heavy loads, they are prone to forklift wheel misalignment. While the degree of misalignment is usually small and doesn't directly affect loading, unloading, stacking, or transport operations, it can lead to parking brake failure or reduced braking effectiveness, impacting the stability and safety of forklift operation. In actual production, this problem is solved by replacing the entire forklift's driving wheel assembly. However, because driving wheel misalignment occurs frequently, replacing the entire assembly just to ensure parking brake functionality unnecessarily increases forklift maintenance costs, hindering production cost control. Utility Model Content

[0005] The present invention adopts the following technical solution to solve the technical problem: a hydraulic forklift moving wheel limiting device, comprising a connecting part and a pair of limiting platforms;

[0006] Both of the aforementioned limiting platforms are fixedly installed to the connecting part and are respectively located on the front and rear sides of the forklift's driving wheel, restricting the driving wheel from rolling forward or backward.

[0007] Furthermore, the side of the limiting platform facing the moving wheel is an upward slope with increasing height in the direction away from the moving wheel.

[0008] Furthermore, the side of the limiting platform facing the moving wheel is shaped as an upward slope that fits against the outer edge of the moving wheel.

[0009] Furthermore, the limiting platform has a corner plate-like structure with its ridge line located at the top.

[0010] Furthermore, the limiting platform is an angle iron.

[0011] Furthermore, the limiting platform and the connecting part are welded and fixed to form an integral structure.

[0012] Furthermore, this also includes lifting levers;

[0013] The lifting rod is erected above the connecting part, and its bottom end is fixed to the top of the connecting part.

[0023] To make the objectives, technical solutions, and advantages of the embodiments of this utility model clearer, the technical solutions of the embodiments of this utility model will be clearly and completely described below in conjunction with the embodiments of this utility model. Obviously, the described embodiments are only some embodiments of this utility model, not all embodiments. Based on the embodiments of this utility model, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of this utility model.

[0024] A hydraulic forklift drive wheel limiting device, such as Figures 1-2 As shown, its structural relationship is as follows: it includes a connecting part 2 and a pair of limiting platforms 3;

[0025] A pair of limiting platforms 3 are fixedly installed to the connecting part 2 and are located on the front and rear sides of the driving wheel 11 of the forklift 1, respectively, to restrict the driving wheel 11 from rolling forward or backward.

[0026] Preferably, the side of the limiting platform 3 facing the moving wheel 11 is an upward slope with increasing height in the direction away from the moving wheel.

[0027] Preferably, the side of the limiting platform 3 facing the moving wheel 11 is an upward slope that fits against the outer edge of the moving wheel 11.

[0028] Preferably, the limiting platform 3 has a corner plate-like structure with the ridge line located at the top.

[0029] Preferably, the limiting platform 3 is an angle iron.

[0030] Preferably, the limiting platform 3 and the connecting part 2 are welded and fixed to form an integral structure.

[0031] Preferably, it also includes a lifting rod 4;

[0032] The lifting rod 4 is erected above the connecting part 2, and its bottom end is fixed to the top of the connecting part 2. The staff can easily put on and take off the limiting device by applying force to the lifting rod 4.

[0033] Preferably, the bottom end of the lifting rod 4 is welded and fixed to the top of the connecting part 2.

[0034] Preferably, the top of the lifting rod 4 is bent downwards into a hook shape.

[0035] When using the above-mentioned hydraulic forklift driving wheel limiting device to limit the parking brake of the driving wheel 11, the braking function of the driving wheel assembly is first used to initially limit the driving wheel 11. Then, the operator moves and places the limiting device by holding the lifting rod 4, so that a pair of limiting platforms 3 are respectively located on the front and rear sides of the driving wheel 11, so that the limiting platform 3 contacts the driving wheel 11 when the driving wheel 11 deviates from its movement, preventing the driving wheel 11 from continuing to move, thereby realizing the parking brake limiting of the driving wheel 11 and ensuring the stability of the forklift when parked.
