Description

Technical Field

[0001] The utility model relates to the technical field of forklift attachments, in particular to a door frame side shifter used for forklift attachments. Background Art

[0002] The forklift mast side shifter is an important component used to change the travel direction of the forklift. It enables the forklift to turn and reverse more flexibly in narrow passages or warehouses. The working principle of the existing forklift mast side shifter is mainly to achieve the side shift of the mast through hydraulic transmission, thereby changing the travel direction of the forklift.

[0003] The built-in side shifter of existing forklift standard configuration has a simple structure, and the oil pipe connecting the forklift and the built-in side shifter cannot be fixed. When the built-in side shifter is in working state, the connecting oil pipe moves back and forth as the forklift mast rises and the built-in side shifter shifts sideways, affecting the forklift driver's operating field of view and reducing the service life of the oil pipe. When the built-in side shifter is installed on the forklift mast, since the distance between the side roller in the composite roller and the web of the mast is difficult to control, it needs to be disassembled and adjusted many times, with low installation efficiency, affecting the service life of the composite roller and increasing the assembly cost.

[0004] In view of the above problems, a mast side shifter for forklift attachments is proposed. Utility Model Content

[0005] The purpose of the utility model is to provide a mast side shifter for forklift accessories, which solves the problem that the built-in side shifter of the existing forklift standard configuration in the background technology has a simple structure and the oil pipe cannot be fixed. When the built-in side shifter is installed on the forklift mast, it is difficult to control the distance between the side roller in the composite roller and the mast web, so it needs to be disassembled and adjusted many times, the installation efficiency is low, the service life of the composite roller is affected, and the assembly cost is increased.

[0006] To achieve the above-mentioned purpose, the utility model provides the following technical solutions: a gantry side shifter for forklift accessories, comprising an outer frame mechanism, one side of the outer frame mechanism is movably sleeved with a liftable inner frame mechanism, the lower end of the lift inner frame mechanism is engaged with a gantry side shifting mechanism, the lift inner frame mechanism comprises a lifting frame, three sets of inclined sleeves connected in parallel on one side of the lifting frame, the gantry side shifting mechanism comprises a gantry fixing block obliquely engaged with the inclined sleeve, a forklift slide is slidably arranged in the gantry fixing block, a two-way driving cylinder is fixedly arranged in the gantry fixing block, the two-way driving cylinder can be movably engaged with the gantry fixing block, and one side of the forklift slide is engaged with an L-shaped forklift frame from top to bottom.

[0007] Preferably, the outer frame mechanism includes an outer frame, an oblique driving cylinder connected to both ends of the outer frame, and a lifting driving cylinder vertically arranged at both ends of the outer frame.

[0008] Preferably, side sealing plates are provided at both ends of the portal frame fixing block, and two groups of the side sealing plates are provided. The two groups of the side sealing plates are connected to the portal frame fixing block by screws.

[0009] Preferably, oblique interfaces are arranged in parallel on one side of the door frame fixing block, and sliding grooves are arranged at the sliding parts of the door frame fixing block corresponding to the upper and lower ends of the forklift slide.

[0010] Preferably, a positioning slot is provided at one end of the forklift slide, an oblique slot is provided at the upper end of the forklift slide, and a driving slot is provided at one side of the forklift slide.

[0011] Preferably, a rotating rack is rotatably provided at the two output ends of the bidirectional driving oil cylinder.

[0012] Preferably, an oblique groove is provided at the upper end of the L-shaped forklift frame, a positioning slot is provided at the middle of the L-shaped forklift frame, and the shape of the L-shaped forklift frame matches the forklift slide frame.

[0013] Preferably, the gantry side shift mechanism further comprises a T-shaped plug block inserted into the positioning slot, and a corresponding T-shaped plug block is also provided on the forklift slide.

[0014] Compared with the prior art, the beneficial effects of the utility model are as follows:

[0015] 1. The utility model provides a gantry side shifter for forklift attachments. By means of the oblique engagement arrangement of the lifting inner frame mechanism and the gantry side shifting mechanism, the gantry side shifting mechanism can make the oblique sleeve plate fit with the gantry fixing block under the action of gravity. The heavier the weight forked on the gantry side shifting mechanism, the more stable the connection between the oblique sleeve plate and the gantry fixing block. The gantry fixing block can be disassembled by lifting it obliquely upwards, and the disassembly is simple. This solves the problems of the existing forklift standard configuration of the built-in side shifter having a simple structure, the inability to fix the oil pipe, the need for multiple disassembly and adjustment, and the low installation efficiency.

[0016] 2. The utility model provides a gantry side shifter for forklift accessories. Through the coordinated arrangement of the gantry fixing block, the two-way drive cylinder and the forklift slide in the gantry side shift mechanism, the two-way drive cylinder can drive the forklift slides on both sides to move along the gantry fixing block to achieve horizontal shifting. The two-way drive cylinder can be disconnected or connected with the forklift slide by rotating one end, and the forklift slide can be taken out along the gantry fixing block. The built-in side shifter of the forklift with this structure is relatively simple to disassemble, assemble and adjust, and has high installation efficiency, and will not increase the assembly cost. It solves the problem that the built-in side shifter of the existing standard configuration of forklifts has low installation efficiency, affects the service life of the composite roller, and increases the assembly cost.
