DETAILED DESCRIPTION

[0034] The following combination Figures 1 to 6 The utility model is described in further detail.

[0035] The utility model discloses a hydraulic forklift wheel protection device. Figures 1 to 6A hydraulic forklift wheel protection device mainly includes a protection mechanism 100, a wheel 200 and a frame 300. The protection mechanism 100 is arranged on the frame 300, and the wheel 200 is rotatably arranged on the frame 300. When the wheel 200 rolls, the protection mechanism 100 can block objects on the running track of the wheel 200, reducing the possibility of the wheel 200 being crushed by external objects, thereby improving the safety of the device.

[0036] Reference Figure 1 The protection mechanism 100 includes two groups of protection components 110, two groups of adjustment components 120 and a locking component 130. The two groups of protection components 110 are respectively arranged on the front and rear sides of the moving direction of the wheel 200, and one group of protection components 110 corresponds to one group of adjustment components 120; the protection component 110 includes a protection plate 111, a connecting rod 112, two inclined plates 113 and two side plates 114. The connecting rod 112 is slidably penetrated on the frame 300. The protection plate 111 is arranged at one end of the connecting rod 112 through the adjustment component 120. The inclined plate 113 is inclined, and the inclined plate 113 is respectively fixed to the upper and lower ends of the protection plate 111 by welding, and the side plates 114 are respectively fixed to the two sides of the protection plate 111 by welding.

[0037] When the wheel 200 rolls, the protection plate 111 changes and moves with the wheel 200. By adjusting the distance between the two protection plates 111, the possibility of contact with the wheel 200 is reduced. The protection plate 111 can prevent the possibility of foreign objects being rolled into the wheel 200, and reduce the possibility of the wheel 200 being locked after the foreign objects enter the wheel 200. At the same time, when the operator performs improper operation, the possibility of the operator's feet being crushed by the wheel 200 is reduced, thereby improving the safety of the device; at the same time, the damage to the wheel 200 by the outside world is reduced, thereby protecting the wheel 200.

[0038] There is a certain inclination angle between the inclined plate 113 and the ground, which can effectively prevent foreign objects from being rolled into the wheel 200, and at the same time enable the forklift to travel normally on an uneven road surface with a certain inclination angle; the side plate 114 protects and blocks the rotating surface of the wheel 200, further reducing the possibility of foreign objects entering the wheel 200 from the side of the wheel 200, thereby improving the safety of the device.

[0039] Reference Figures 2 to 4The adjusting assembly 120 includes an adjusting frame 121, a plurality of first adjusting rods 122, a slide plate 124, a mounting frame 125 and a plurality of second adjusting rods 123. The mounting frame 125 is fixedly mounted on both ends of the connecting rod 112 by bolts. The adjusting frame 121 is slidably mounted on the mounting frame 125 by means of a slider slot. One end of the first adjusting rod 122 away from the adjusting frame 121 is rotatably connected to the protective plate 111 through a waist-shaped hole. The slide plate 124 is slidably mounted on the adjusting frame 121 by means of a slider slot. One end of the first adjusting rod 122 away from the protective plate 111 is threadedly connected to the slide plate 124. A spring is sleeved on the first adjusting rod 122 for adjusting the assembly force between the protective plate 111 and the slide plate 124. One end of the second adjusting rod 123 is rotatably connected to the mounting frame 125 through a bearing, and the other end of the second adjusting rod 123 is threadedly connected to the adjusting frame 121.

[0040] The first adjusting rod 122 is used to install the protection plate 111 on the adjusting frame 121. By rotating the first adjusting rod 122, the distance between the protection plate 111 and the adjusting frame 121 is changed, thereby adjusting the spacing between the two protection plates 111, thereby reducing the possibility of wheel rubbing.

[0041] When encountering an uneven road surface, causing the lower end of the protection plate 111 to hit foreign objects or the operator's feet, the protection plate 111 can slide on the adjustment frame 121 along with the slide plate 124, thereby reducing the impact of the protection plate 111 on the road surface, further improving the safety of the device, and at the same time does not affect the lateral protection effect of the protection plate 111.

[0042] When the height of the protective plate 111 needs to be adjusted, the second adjusting rod 123 is rotated to make the adjusting frame 121 slide on the mounting frame 125, thereby adjusting the height of the protective plate 111 and improving the applicability of the device; when the protective plate 111 is adjusted to the highest height, the protective plate 111 is still in contact with the ground, which proves that the wheel 200 is severely worn, reminding personnel to replace the wheel 200.

[0043] Reference Figure 1 , Figure 5 and Figure 6 The locking assembly 130 includes a locking block 131, a transmission rod 132 and a return spring 133. The transmission rod 132 is rotatably arranged on the frame 300 through a bearing. The transmission rod 132 is connected to the rotating shaft of the wheel 200 through a key transmission. The locking block 131 is fixed to the transmission rod 132 by welding or bolts. A locking groove 134 is provided on the connecting rod 112. The locking block 131 is in the locking groove 134. One end of the return spring 133 is arranged on the frame 300, and the other end of the return spring 133 is arranged on the connecting rod 112.

[0044] When lateral extrusion occurs, the protection plate 111 moves laterally, pushing the connecting rod 112 to move on the frame 300, so that the locking block 131 contacts and locks the connecting rod 112 at the edge of the locking groove 134, so that the rotating shaft of the wheel 200 stops rotating, thereby braking the wheel 200, further reducing the possibility of the wheel 200 being crushed, and at the same time reducing the impact force of the protection plate 111 on the colliding objects, thereby improving safety.

[0045] After the wheel 200 is locked, when the forklift is moved to a safe area, the elastic force of the return spring 133 restores the connecting rod 112 to its initial position, and the locking block 131 returns to the locking groove 134, so that the wheel 200 can rotate again; at the same time, the return spring 133 can absorb the impact force of the protection plate 111, reduce damage to the impact object, and improve the safety of the device.

[0046] The implementation principle of a hydraulic forklift wheel protection device in the embodiment of the utility model is:

[0047] When the wheel 200 rolls, the protection component 110 can block objects on the running track of the wheel 200, reducing the possibility of the wheel 200 being crushed by external objects, thereby improving the safety of the device; the position of the protection component 110 is adjusted by adjusting the component 120, so that the device can be applied to a variety of environments, while improving the protective effect of the protection component 110; through the locking component 130, when the protection plate 111 is squeezed and colliding with an object, the wheel 200 is braked in time, reducing the impact force on the objects, while reducing the damage to the protection plate 111, thereby improving the safety of the device.

[0048] The above are all preferred embodiments of the present utility model, and are not intended to limit the protection scope of the present utility model. Therefore, any equivalent changes made based on the structure, shape, and principle of the present utility model should be included in the protection scope of the present utility model.
