Description

Technical Field

[0001] The present application relates to the technical field of forklift accessories, and in particular to a cargo anti-dumping device for an intelligent forklift. Background Art

[0002] A smart forklift is an automated logistics handling equipment. It usually integrates multiple sensor technologies to achieve precise positioning and navigation. It uses advanced technology to load, unload, stack and transport goods over short distances, and delivers the goods to the designated location.

Although the above-mentioned prior art solution drives the screw to rotate by rotating the dual-axis motor, so that the trapezoidal block and the mounting plate move toward the center at the same time to fix the bottom end of the material, which has the beneficial effect of preventing the material from dumping, it still has the following defects:

[0004] When goods are transported on smart forklifts, the heights of the goods to be transported are different. The higher the goods, the higher their center of gravity. Some goods need to be stacked together for transportation. Therefore, if only the bottom is fixed, the stability of the entire goods will be greatly reduced, and it is easy to tip over during transportation.

[0005] In view of this, we propose a cargo anti-dumping device for an intelligent forklift. Utility Model Content

[0027] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the embodiments described are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0028] Reference Figure 1-6 The present application provides a cargo anti-dumping device for an intelligent forklift, comprising a vehicle body 1, a controller provided on the vehicle body 1, a gantry 2 provided at the front end of the vehicle body 1, a fork arm 3 slidably mounted on the gantry 2, an electric telescopic rod provided on the gantry 2 for driving the fork arm 3 to move up and down, and the electric telescopic rod being electrically connected to the controller;

[0029] An anti-dumping mechanism is provided on the fork arm 3 at one end away from the fork foot. The anti-dumping mechanism includes a vertical mounting frame 4 and two sets of anti-dumping frames. The two sets of anti-dumping frames are symmetrically arranged at the left and right ends of the vertical mounting frame 4. The anti-dumping frame includes a side frame 5, a cross bar 6 and a hinged rod 7. There are two side frames 5. The distance between the two side frames 5 is adjustable. A limiting groove 10 is provided on the vertical mounting frame 4. A bidirectional threaded screw rod 11 is rotatably connected to the limiting groove 10 through a bearing. A screw sleeve 12 is symmetrically connected to the bidirectional threaded screw rod 11 through a thread. The screw sleeve 12 is slidingly connected in the limiting groove 10. The screw sleeve 12 is respectively The second motor 13 is fixedly connected to the bottom of the end of the corresponding side frame 5 close to the vehicle body 1, and the second motor 13 is installed on the vertical mounting frame 4 through a bracket. The output end of the second motor 13 is fixed to one end of the bidirectional threaded screw 11 through a coupling. The second motor 13 is electrically connected to the controller. The controller drives the second motor 13 to control the rotation of the bidirectional threaded screw 11. When the bidirectional threaded screw 11 rotates, the two sets of screw sleeves 12 move on the surface of the bidirectional threaded screw 11, which can drive the two sets of side frames 5 to approach each other, so that the side frames 5 drive the cross bar 6 and the hinged rod 7 to approach the two sides of the cargo for fixation;

[0030] The cross bar 6 is provided just above the side frame 5. A scissor-shaped hinged rod 7 is connected between the side frame 5 and the cross bar 6. One end of the two rod bodies of the hinged rod 7 is respectively connected to the rear ends of the cross bar 6 and the side frame 5 through a rotating shaft. The front ends of the cross bar 6 and the side frame 5 are both provided with a sliding groove extending backward. A slider is slidably installed in the sliding groove. The other ends of the two rod bodies of the hinged rod 7 are respectively connected to the upper and lower sliders through a rotating shaft.

[0031] A threaded rod 8 is rotatably connected to the slide groove opened at the front end of the side frame 5 through a bearing. A screw hole is opened on the lower slider, and the threaded rod 8 is threadedly connected to the lower slider through the screw hole. A first motor 9 is installed on the side frame 5 through a bracket. The output end of the first motor 9 is fixed to one end of the threaded rod 8 through a coupling. The first motor 9 is electrically connected to the controller. By driving the first motor 9, the threaded rod 8 is controlled to rotate, and then the lower slider slides in the slide groove opened at the front end of the side frame 5, so that the scissor-shaped hinged rods 7 are raised and lowered, thereby fixing and supporting some higher sides of the cargo.

[0032] It is worth noting that:

[0033] A support rod 14 is symmetrically fixed to one end of the side frame 5 close to the vehicle body 1, and a slide rail is symmetrically opened on the vertical mounting frame 4. A limit block is slidably installed in the slide rail. The limit block is fixedly connected to the upper side of the support rod 14 close to the vehicle body 1. When the support rod 14 moves closer or farther away with the side frame 5, the limit block is used to limit and support the support rod 14.

[0034] Another slide rail is provided on the side of the support rod 14 away from the vehicle body 1, and another limit block is slidably installed in the other slide rail, and the other limit block is fixedly connected to the cross bar 6. When the scissor-shaped hinged rods 7 are controlled to rise and fall, the cross bar 6 can move up and down stably under the limiting action of the other limit block.

[0035] The implementation principle of the cargo anti-dumping device of an intelligent forklift in the embodiment of the present application is as follows:

[0036] First, the goods to be transported are stacked on the fork arm 3, and the second motor 13 is controlled to start by the controller, wherein the controller sends a signal, and receivers are provided in the second motor 13 and the first motor 9. When the receiver receives the signal, the received signal is decoded, and the receiver controls the second motor 13 or the first motor 9 to start according to the received signal. When the second motor 13 is started, the bidirectional threaded screw 11 is controlled to rotate. During the rotation of the bidirectional threaded screw 11, the screw sleeve 12 can be driven to move on the surface of the bidirectional threaded screw 11, thereby driving the two side frames 5 to approach each other. At this time, the limit block slides in the corresponding slide rail, so that the support rod 14 drives the cross bar 6 and the hinged rod 7 to approach the side of the goods, thereby clamping and fixing the side of the goods;

[0037] The controller is used to control the first motor 9 to start, so that the first motor 9 controls the threaded rod 8 to rotate. At this time, the threaded rod 8 drives the next slider to slide within the sliding groove opened at the front end of the side frame 5, and controls the scissor-shaped hinged rod 7 to rise and fall. During the lifting process, the upper slider moves in the sliding groove opened at the front end of the cross bar 6, so that the cross bar 6 and the hinged rod 7 fix and support some of the higher sides of the cargo.

[0038] The above are all preferred embodiments of the present application, and are not intended to limit the scope of protection of the present application. Therefore, any equivalent changes made based on the structure, shape, and principle of the present application should be included in the scope of protection of the present application.
