Description

Technical Field

[0001] The utility model relates to the technical field of forklifts, in particular to a forklift cargo fork adjusting device. Background Art

[0002] A forklift, also known as a forklift or forklift, is a mechanical device designed specifically for the handling, loading, unloading and stacking of goods. The forks are the part of the forklift that grips and carries the goods. Their design and strength determine the handling capacity and efficiency of the forklift. The length and spacing of the forks can be adjusted to suit the different sizes and shapes of goods, allowing the forklift to safely and stably transfer goods from one location to another.

[0003] However, existing forklift forks usually need to be adjusted manually by staff. Since the forks are relatively heavy, the process of adjusting the spacing is time-consuming and physically demanding. At the same time, when the forklift is moving, the forks are prone to damage surrounding objects, increasing the difficulty of driving. In view of this, we propose a forklift fork adjustment device. Utility Model Content

[0004] The utility model aims to provide a forklift fork adjusting device in view of the problems existing in the background technology.

[0005] The technical solution of the utility model is as follows: a forklift fork adjustment device comprises a bracket, wherein a fork for loading and unloading goods is arranged inside the bracket, a driving assembly for adjusting the width of the fork is installed on the bracket, a limiting assembly for assisting the fork in horizontal movement is arranged at the bottom of the bracket, a hydraulic cylinder for adjusting the height of the driving assembly is installed at the top of the bracket, and positioning bolts for limiting the position of the forks in the storage state are symmetrically arranged on the two side walls of the bracket.

[0006] Preferably, first threaded holes are symmetrically provided on both side walls of the bracket, and the two positioning bolts are respectively arranged in the first threaded holes corresponding to the positions.

[0007] Preferably, the two forks are symmetrically arranged, and positioning holes are opened on the two forks, and the two positioning holes are adapted to positioning bolts corresponding to the positions.

[0008] Preferably, the driving assembly includes a limit slider, a protective cover and a forward and reverse motor are installed on one side wall of the limit slider, and the output end of the forward and reverse motor is connected to a bidirectional threaded rod.

[0009] Preferably, the fork is symmetrically provided with second threaded holes, and the bidirectional threaded rod is arranged in the second threaded holes corresponding in position.

[0010] Preferably, the limiting assembly includes a base, a movable plate is provided on the base, a third threaded hole is formed on the movable plate, and an adjusting bolt is provided in the third threaded hole.

[0011] Preferably, an auxiliary plate is welded to the top of the movable plate, a clamping block is installed on the front-facing wall of the auxiliary plate, and guide blocks are symmetrically installed on both side walls of the auxiliary plate.

[0012] Compared with the prior art, the utility model has the following beneficial technical effects:

[0013] The utility model realizes the adjustment of the height of the fork by starting the hydraulic cylinder to drive the driving component to rise, which is convenient for loading and unloading goods at different heights, and starting the forward and reverse motors to drive the two-way threaded rod can drive the two forks to move in the same direction or in the opposite direction, which is beneficial to adjust the position of the goods according to the width of the goods, without the need for manual adjustment by the staff, saving physical strength and increasing the applicable scope of the lifting device. When the fork is adjusting the width, the clamping block is clamped in the clamping groove on the back of the fork to prevent the fork from rotating simultaneously with the two-way threaded rod during the adjustment process. When the fork moves, the clamping groove can be released, so that the two-way threaded rod drives the fork to rotate in the opposite direction of the bracket and store it, and the positioning bolt is tightened in the positioning hole provided on the fork to achieve the purpose of storing it, avoids affecting the subsequent walking of the forklift, prevents the fork from damaging surrounding objects during the walking process, and reduces the difficulty of operating the forklift during non-working periods.
