A high-strength wear-resistant outer door frame for forklift

Abstract

The utility model discloses a high-strength wear-resistant outer mast for forklifts, comprising an outer mast and a track arranged inside the outer mast for the inner mast to slide, wherein the inner wall of the track is respectively provided with a wear-resistant structure and a lubrication structure. After the utility model installs the rubber wear-resistant frame in the track, when the bearing on the inner mast hits the rubber wear-resistant frame, the rubber wear-resistant frame will buffer and absorb the impact force, thereby reducing the impact force. At the same time, after the lubrication structure is installed on the outer mast, when the bearing on the inner mast moves to the roller position, the roller will be driven to rotate and move to one side of the oil storage cylinder, forcing the piston rod to move to the left to squeeze the solid butter in the oil storage cylinder into the arc groove. The solid butter can be applied to the bearing surface on the inner mast by the rotation of the roller, so that the solid butter can be applied to the rubber wear-resistant frame by the movement of the bearing to form an oil film layer, thereby reducing the friction coefficient between the bearing and the rubber wear-resistant frame and improving the wear resistance of the rubber wear-resistant frame.

Description

Technical Field

[0001] The utility model relates to the technical field of forklift outer door frames, in particular to a high-strength wear-resistant outer door frame for a forklift. Background Art

[0002] The forklift mast is composed of an inner mast, an outer mast, a fork frame, forks, sprockets, chains, a lifting cylinder and a tilting cylinder. The inner mast is located inside the outer mast and slides with the inner track of the outer mast through bearings.

[0003] Since the inner mast of a forklift slides on the track of the outer mast of the forklift through the bearing, there is a certain gap between the inner mast and the track of the outer mast. When the bearing slides on the inner track of the outer mast, the bearing will hit the outer mast due to the gap, which will cause damage to the bearing and wear of the outer mast. For this reason, we propose a high-strength and wear-resistant outer mast for forklifts. Utility Model Content

DETAILED DESCRIPTION

[0022] The technical solutions in the embodiments of the present invention will be described clearly and completely below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all of the embodiments.

[0024] Reference Figure 1-6 A high-strength wear-resistant outer mast for a forklift comprises an outer mast 1 and a track 2 arranged inside the outer mast 1 for sliding movement of an inner mast, wherein the inner wall of the track 2 is respectively provided with a wear-resistant structure and a lubricating structure.

[0025] The wear-resistant structure consists of a rubber wear-resistant frame 3 and an assembly component that can be assembled with the track 2. The assembly component includes T-shaped rubber blocks 4 fixedly installed on the three surfaces of the rubber wear-resistant frame 3. The three inner walls of the track 2 are all provided with T-shaped slots 5 that are compatible with the T-shaped rubber blocks 4. The rubber wear-resistant frame 3 is placed into the track 2, and then the T-shaped rubber blocks 4 are inserted into the T-shaped slots 5, so that the rubber wear-resistant frame 3 can be preliminarily positioned.

[0026] The upper and lower surfaces of the rubber wear-resistant frame 3 are fixedly mounted with rubber plates 18, and the surfaces of the rubber plates 18 and the upper and lower surfaces of the outer door frame 1 are provided with bolt holes 14. After the rubber wear-resistant frame 3 is initially positioned, the rubber plates 18 on the upper and lower surfaces of the rubber wear-resistant frame 3 are respectively contacted with the upper and lower surfaces of the outer door frame 1, and then the rubber plates 18 are fixed by screwing external bolts into the bolt holes 14, so that the rubber wear-resistant frame 3 can be stably fixed in the track 2 to prevent the rubber wear-resistant frame 3 from moving. After the rubber wear-resistant frame 3 is installed in the track 2 using the assembly components, when the bearing on the inner door frame hits the rubber wear-resistant frame 3, the rubber wear-resistant frame 3 will buffer and absorb the impact force, thereby reducing the impact force.

[0027] The lubrication structure includes an oil storage cylinder 6, the inner wall of which is slidably mounted a piston rod 7, one end of which extends to the outside of the oil storage cylinder 6 and is fixedly mounted a roller seat 8, the inner wall of the roller seat 8 is rotatably connected to a roller 9, the inner wall of the roller seat 8 is provided with an arc groove 10 for the roller 9 to move, and the left end of the piston rod 7 is provided with an oil delivery channel 11 that penetrates to the inner wall of the arc groove 10.

[0028] The surfaces of the outer door frame 1 and the rubber wear-resistant frame 3 are provided with mounting grooves 15 for the oil storage cylinder 6 to pass through, a flange 16 is fixedly installed at one end of the oil storage cylinder 6, and the inner wall of the mounting groove 15 on the outer door frame 1 is provided with an embedding groove 17 that is compatible with the flange 16, and the inner wall of the embedding groove 17 and the surface of the flange 16 are provided with mounting holes. The oil storage cylinder 6 is inserted into the mounting groove 15, and the flange 16 will be in the embedding groove 17 at this time. Then, the oil storage cylinder 6 can be fixed by screwing an external bolt into the mounting hole.

[0029] An oil filling port 13 is provided on the surface of the oil storage cylinder 6, and butter can be injected into the oil storage cylinder 6 through the oil filling port 13. A compression spring 12 is sleeved on the surface of the piston rod 7, and both ends of the compression spring 12 are fixedly connected to the roller seat 8 and the opposite surfaces of the oil storage cylinder 6 respectively. In the initial state, the compression spring 12 can drive the roller 9 to be inside the rubber wear-resistant frame 3.

[0030] After the lubrication structure is installed on the outer door frame 1, the roller 9 will be in the track 2. When the bearing on the inner door frame moves to the position of the roller 9, the roller 9 will be driven to rotate and move to one side of the oil storage cylinder 6, forcing the piston rod 7 to move to the left to squeeze the solid butter in the oil storage cylinder 6 along the oil delivery channel 11 into the arc groove 10. The solid butter in the arc groove 10 can be applied to the bearing surface on the inner door frame by rotating the roller 9, so that the solid butter can be applied to the rubber wear-resistant frame 3 to form an oil film layer by the movement of the bearing, thereby reducing the friction coefficient between the bearing and improving the wear resistance of the rubber wear-resistant frame 3. When the bearing on the inner door frame is separated from the roller 9, the compression spring 12 will be reset. At this time, the piston rod 7 moves to the right, so that the butter in the arc groove 10 can be re-sucked into the oil storage cylinder 6, avoiding excessive waste of butter.

[0031] The above is only a preferred specific implementation manner of the present invention, but the protection scope of the present invention is not limited thereto. Any technician familiar with the technical field can make equivalent substitutions or changes within the technical scope disclosed by the present invention according to the technical solution and inventive concept of the present invention, which should be covered by the protection scope of the present invention.
