Description

Technical Field

[0001] This utility model belongs to the technical field of forklift mast components, specifically relating to a rubber hose roller for a new energy forklift mast. Background Technology

[0002] New energy forklifts are a type of industrial handling vehicle. They are wheeled handling vehicles that use new energy sources to load, unload, stack, and transport palletized goods over short distances. They are widely used in stations, ports, airports, factories, warehouses, and other fields. The forklift mast is the main load-bearing structure of the forklift's lifting device. It consists of an inner mast, outer mast, fork carriage, forks, sprockets, chains, lifting cylinders, and tilting cylinders. The safe connection of the sprockets and chains is crucial for ensuring the vertical movement of the forklift mast.

[0003] Currently, the roller connection method of existing new energy forklift masts is mostly a one-piece structure, which is inconvenient for replacement and disassembly, and requires the entire frame to be replaced, resulting in high replacement costs. Therefore, the existing welding fixture structure of the external mast of new energy forklifts needs further improvement. Utility Model Content

[0004] The purpose of this utility model is to overcome the shortcomings of the existing technology and provide a rubber hose roller for the mast of a new energy forklift. It has the characteristics of compact structure, good connection stability, smooth sliding, convenient installation and disassembly, and low replacement cost. It can be widely used in the production technology field of the outer mast of new energy forklifts.

[0005] To achieve the above objectives, the present invention adopts the following technical solution: a rubber hose roller for a new energy forklift mast, comprising a pulley frame, wherein the pulley frame has a hollow structure inside and a groove on its surface; the pulley frame is connected to a bushing through the hollow structure, and a connecting rod is provided inside the bushing.

[0006] As an improvement, the middle circle of the pulley frame has a stepped structure, which facilitates the installation and fixing of the bushing.

[0007] As an improvement, the pulley frame is made of high-strength rubber or nylon.

[0008] As an improvement, the groove is a full-circle U-shaped groove with a straight section on the bottom and rounded chamfers on both sides.

[0009] As an improvement, the length of the straight segment is 8~15mm, and the size of the rounded chamfer is R15~R35mm, so that the roller slides more smoothly on the chain.

[0010] As an improvement, the bushing has a cylindrical structure with a circular step at the top and a hollow hole inside.

[0011] As an improvement, the bottom of the bushing protrudes from the pulley frame by a distance of 10~25mm.

[0012] As an improvement, the connecting rod is a T-shaped solid column structure with a threaded head. The hose roller is fixed to the column of the forklift mast through the thread, ensuring smooth and reliable mast lifting and lowering.

[0013] As an improvement, the connecting rod is made of galvanized carbon steel or stainless steel.

[0014] The beneficial effects of this utility model are as follows: A rubber hose roller for a new energy forklift mast has the characteristics of compact structure, good connection stability, smooth sliding, convenient installation and disassembly, and low replacement cost; by disassembling the roller into three parts—pulley frame, bushing, and connecting rod—the installation and disassembly of the roller are facilitated, and the replacement cost is also lower; by setting straight sections and rounded chamfers inside the groove of the pulley frame, the smoothness of the roller's sliding on the chain is improved, and the operation is more stable; in addition, by setting the connecting rod as a T-shaped cylinder with a threaded structure at the head, the bushing can rotate freely inside, while the roller can be fixed to the mast column as a whole, making the structure more compact and practical.

[0017] The preferred embodiments of this utility model will now be described in detail with reference to the accompanying drawings.

[0018] like Figures 1-2As shown in the figure, a new energy forklift mast hose roller of this embodiment includes a pulley frame 1, the pulley frame 1 has a hollow structure 11 inside and a groove 12 on the surface; the pulley frame 1 is connected to a bushing 2 through the hollow structure 11, and a connecting rod 3 is provided inside the bushing 2.

[0019] Furthermore, the middle circle of the pulley frame 1 has a stepped structure, which facilitates the installation and fixing of the bushing 2. Specifically, the thickness of the middle circle step of the pulley frame 1 is 7~12mm, with an installation gap of 0.1~0.5mm in the middle; specifically, the pulley frame 1 is made of high-strength rubber or nylon material, preferably high-strength nylon material.

[0020] Furthermore, such as Figure 3 As shown, the pulley frame 1 has a hollow structure 11 inside and a groove 12 on its surface. The groove 12 is a full-circle U-shaped groove with a straight section 121 on the bottom and rounded chamfers 122 on both sides. Specifically, the length of the straight section 121 is 8~15mm, preferably 10mm, and the size of the rounded chamfers 122 is R15~R35mm, preferably R25~R30mm, so that the roller slides more smoothly on the chain and the gantry runs more stably and reliably.

[0021] Furthermore, such as Figure 4 As shown, the bushing 2 is a cylindrical structure with a circular step 21 at the top and a hollow hole 22 inside; specifically, the thickness of the circular step 21 is 2~5mm, preferably 2.5mm~3.5mm, and the hollow hole 22 has straight chamfers 23 at both ends to facilitate the assembly of the connecting rod.

[0022] Furthermore, the bottom of the bushing 2 protrudes from the pulley frame 1 by a distance of 10~25mm, preferably 10~15mm. The protruding part makes the connection more stable and the disassembly more convenient.

[0023] Furthermore, such as Figure 5 As shown, the connecting rod 3 is a T-shaped solid column structure with a thread 31 at the head. The hose roller is fixed to the column of the forklift mast through the thread 31 to ensure smooth and reliable mast lifting and lowering. Specifically, the connecting rod 3 is made of galvanized carbon steel or stainless steel, preferably stainless steel, which can provide better load-bearing strength, facilitate the free rotation of the bushing 2 on the surface of the connecting rod 3, and extend the service life of the connecting rod 3.

[0024] The new energy forklift mast hose roller of this utility model has the characteristics of compact structure, good connection stability, smooth sliding, convenient installation and disassembly, and low replacement cost. By first installing the bushing 2 into the pulley frame 1, and then assembling the connecting rod 3 into the bushing 2, the hose roller is fixed to the column of the forklift mast by the thread 31 on the top of the connecting rod 3. The pulley frame 1 rotates inside the bushing 2, so that the sprocket slides freely in the groove 12 inside the pulley frame 1, realizing the normal operation of the hose roller.

[0025] Finally, it should be noted that the above examples are merely specific embodiments of this utility model. Obviously, this utility model is not limited to the above embodiments and can have many variations. All variations that can be directly derived or conceived by those skilled in the art from the disclosure of this utility model should be considered within the protection scope of this utility model.
