Description

Technical Field

[0001] The utility model relates to the technical field of pallet jack robots, in particular to a driving floating mechanism for pallet jack robots. Background Technique

[0002] A pallet jack is a transportation tool, also known as a pallet truck, forklift, or transporter. It is specifically designed to perform handling, transportation, loading, and positioning tasks in industrial and logistics departments. They can reduce physical labor, improve production efficiency, lower labor costs and risks in the workplace. Their small size and flexible steering make them very suitable for handling goods in limited spaces such as warehouses and workshops.

[0003] Pallet jack robots generally have liftable forks for lifting goods. Rollers are installed at the bottom of the ends of the forks away from the main body. In order to ensure that the rollers are in contact with the ground while the forks are lifted, a driving floating mechanism is needed. Summary of the Invention

[0004] The purpose of the utility model is to provide a driving floating mechanism for pallet jack robots to solve the problems raised in the above background technique.

[0005] To achieve the above purpose, the utility model provides the following technical solution: A driving floating mechanism for pallet jack robots includes a moving mechanism installed on one side of the bottom end of the fork, and also includes a driving bracket hinged under the fork and a driving member for pushing the driving bracket to rotate around the hinge point. One end of the driving bracket is rotatably connected to the moving mechanism. The driving bracket includes a first connecting rod and a second connecting rod obliquely and fixedly connected to one end of the first connecting rod. The connection part of the first connecting rod and the second connecting rod is rotatably connected to the fork. The end of the first connecting rod away from the second connecting rod is rotatably connected to the moving mechanism. The end of the second connecting rod away from the first connecting rod is rotatably connected to the driving member.

[0006] Further, two first connecting rods and two second connecting rods are provided. The two first connecting rods and the two second connecting rods are symmetrically arranged at both axial ends of the moving mechanism. A third connecting rod is fixedly connected to the ends of the two second connecting rods away from the first connecting rods. One end of the driving member is provided with a connecting piece rotatably connected to the third connecting rod.

[0007] Further, a connecting seat is provided at the end of the driving member away from the connecting piece.

[0008] Further, the moving mechanism includes a bracket and a plurality of rollers rotatably arranged inside the bracket.

[0009] Furthermore, a support roller is rotatably arranged at the top end of the fork, and the support roller corresponds to the roller one by one and is axially parallel. When the moving mechanism moves to the top end, the roller abuts against the support roller.

[0010] Furthermore, a cleaning layer is provided on the outer side wall of the supporting roller.

[0011] Compared with the prior art, the beneficial effects of the utility model are:

[0012] By setting a moving mechanism, a driving bracket and a driving member, the driving member drives the driving bracket to rotate around the hinge point with the fork, and then drives the moving mechanism to rise and fall. When the fork lifts the goods, the moving mechanism extends downward, thereby improving the stability during transportation;

[0013] By installing a support roller at the bottom end of the fork, the top of the moving mechanism is retracted into the fork to reduce the wear caused by the collision between the moving mechanism and the fork. At the same time, a cleaning layer is provided on the outside of the support roller to clean the moving mechanism. BRIEF DESCRIPTION OF THE DRAWINGS

[0022] Please refer to Figures 1-5 , an embodiment provided by the present utility model: a driving floating mechanism for a pallet truck robot, including a moving mechanism 1 installed on one side of the bottom end of the forklift fork 4. The moving mechanism 1 includes a bracket 101 and two rollers 102 rotatably arranged inside the bracket 101. It also includes a driving bracket 2 hinged below the forklift fork 4 and a driving member 3 that pushes the driving bracket 2 to rotate around the hinge point. One end of the driving bracket 2 is rotatably connected to the moving mechanism 1. Refer to the attached Figure 3 , the driving bracket 2 includes a first connecting rod 201 and a second connecting rod 202 obliquely and fixedly connected to one end of the first connecting rod 201. The included angle between the first connecting rod 201 and the second connecting rod 202 is an obtuse angle. The connection between the first connecting rod 201 and the second connecting rod 202 is rotatably connected to the bottom end of the forklift fork 4 through a pin shaft. One end of the first connecting rod 201 away from the second connecting rod 202 is rotatably connected to the middle of the bracket 101 through a pin shaft. One end of the second connecting rod 202 away from the first connecting rod 201 is rotatably connected to the driving member 3.

[0023] In this embodiment, there are two first connecting rods 201 and two second connecting rods 202. The two first connecting rods 201 and the second connecting rods 202 are symmetrically arranged at both axial ends of the moving mechanism 1. At one end of the two second connecting rods 202 away from the first connecting rod 201, a third connecting rod 203 is fixedly connected. The third connecting rod 203 connects the two first connecting rods 201 and the two second connecting rods 202 into one body. One end of the driving member 3 is provided with a connecting member 301 rotatably connected to the third connecting rod 203. Specifically, the third connecting rod 203 is a cylindrical structure, and the connecting member 301 is specifically a circular tubular structure adapted thereto, sleeved outside the third connecting rod 203 and rotatable relative to it. In this embodiment, the driving member 3 is a rod-shaped structure. At one end of the driving member 3 away from the connecting member 301, a connecting seat 302 is provided. The connecting seat 302 is rotatably connected with a mounting rod, and the mounting rod is connected to the pallet truck robot. The mounting rod pushes the connecting seat 302 to move up and down, and then drives the driving bracket 2 to rotate, driving the moving mechanism 1 to move downward. Further, the driving member 3 can also be set as a linear driving member such as a hydraulic telescopic rod (not shown in the figure) according to needs. One end of the hydraulic telescopic rod is rotatably connected to the bottom end of the forklift 4, and the output end is rotatably connected to the third connecting rod 203. By its telescopic movement, it pushes the driving bracket 2 to rotate around the hinge point with the forklift 4, and then drives the moving mechanism 1 to move up and down.

[0024] Further, a support roller 5 is rotatably provided at the top end inside the forklift 4, and the support roller 5 corresponds to the roller 102 one by one and is axially parallel. When the moving mechanism 1 moves up to the topmost position, the roller 102 abuts against and is in rolling connection with the support roller 5, receiving the top end of the moving mechanism 1 into the inside of the forklift 4, reducing the wear caused by the impact between the moving mechanism 1 and the forklift 4. At the same time, a cleaning layer 501 is provided on the outer side of the support roller 5, which can clean the moving mechanism 1. At the same time, the cleaning layer 501 and the roller 102 are in flexible contact, which can reduce the noise generated by the impact.

[0025] Working principle: When in use, after the forklift 4 is inserted into the bottom end of the goods pallet, the robot host drives the forklift 4 to move upward to lift the goods. At the same time, the driving member 3 pushes the driving bracket 2 to rotate around the hinge point with the forklift 4. When the driving member 3 pushes the end of the second connecting rod 202 away from the first connecting rod 201 to move upward, the end of the first connecting rod 201 away from the second connecting rod 202 moves downward synchronously, and then pushes the moving mechanism 1 to move downward, making the roller 102 abut against the ground, improving the stability of the pallet truck robot during movement.

[0026] For those skilled in the art, it is obvious that the present utility model is not limited to the details of the above-mentioned exemplary embodiments, and the present utility model can be implemented in other specific forms without departing from the spirit or basic characteristics of the present utility model. Therefore, from any point of view, the embodiments should be regarded as exemplary and non-limiting. The scope of the present utility model is defined by the appended claims rather than the above description. Therefore, all changes falling within the meaning and scope of the equivalent elements of the claims are intended to be embraced within the present utility model. Any reference signs in the claims should not be construed as limiting the claims involved.
