Description

Technical Field

[0001] The utility model belongs to the technical field of anti-tipping, in particular to an anti-tipping device for a forklift. Background Art

[0002] A forklift is a vehicle used to stack, load and unload goods and transport them over short distances. It is currently widely used in factory warehouses and workshops as well as ports. Forklifts can be divided into electric, internal combustion engine-driven, and manual types. Internal combustion engine-driven forklifts are generally used in ports to stack or load and unload containers.

[0003] When existing forklifts stack containers at ports, they raise the gantry and use the sling to lift the container, then drive the sling to move the container upward, and then lower the container after it moves to the designated position. During long-term use and observation, it was found that when existing forklifts stack containers at ports, there is a problem that when the gantry of the forklift is raised to a high height and the sling lifts a heavier container, the forklift may tip over while driving.

[0004] To this end, the utility model provides a forklift anti-dumping device. Utility Model Content

[0005] In order to make up for the deficiencies of the prior art and solve at least one problem raised in the background art, an anti-dumping device for a forklift is proposed.

[0006] The technical solution adopted by the present invention to solve its technical problems is: the anti-dumping device of a forklift described in the present invention comprises a forklift body; the end of the forklift body is connected to a gantry; the middle of the gantry is connected to a sling; the bottom of the forklift body is fixedly connected to a first fixed plate; the side wall of the first fixed plate is fixedly connected to a first electric push cylinder; the end of the first electric push cylinder is fixedly connected to a second fixed rod; the bottom of the second fixed rod is rotatably connected to a pair of universal wheels; this step drives the second fixed rod and the universal wheel to move to the bottom of the container when the container is lifted so as to support it from the bottom, so as to reduce the situation where the forklift body tips forward during driving due to the high height and heavy weight of the container, so as to increase the safety and stability of the stacking.

[0007] Preferably, a third fixed plate is fixed to the top of the gantry; a second electric push cylinder is fixed to the bottom of the third fixed plate; and a fourth fixed plate is fixed to the end of the second electric push cylinder. This step limits the height of the container stacking by setting the second electric push cylinder to push the fourth fixed plate to a specified position, thereby controlling the height within a safe range, so as to reduce the situation where the forklift body may tip over due to the lifting of the container too high by the sling, thereby improving the safety of stacking containers.

[0008] Preferably, a plurality of sliding holes are opened in the middle of the fourth fixing plate; a damping spring is slidably connected in the sliding hole; in this step, by arranging the damping spring, the container can contact the top of the container when it approaches the fourth fixing plate, and shrink to produce a buffering effect, thereby reducing the damage caused by the impact caused by direct contact between the top of the container and the fourth fixing plate.

[0009] Preferably, a suction cup is fixed to the end of the damping spring; the suction cup is located at the bottom end of the damping spring; this step allows the suction cup to be adsorbed on the top of the container, which can play a fixing role when the container is stacked, thereby improving the position stability of the container when it is moved.

[0010] Preferably, a pair of protective covers are detachably mounted on the top of the fourth fixed plate; the protective covers can cover the damping spring; in this step, the damping spring can be protected by setting the protective covers to cover the damping spring from the top of the fourth fixed plate, so as to reduce the corrosion of the damping spring caused by dust and moisture in the air, resulting in reduced function.

[0011] Preferably, a counterweight box is fixedly connected to the end of the forklift body; a plurality of counterweight blocks are provided on the inner side wall of the counterweight box; this step can increase the weight of the tail of the forklift body by arranging the counterweight box and the counterweight blocks, and when the forklift body is traveling, the counterweight box and the counterweight blocks exert downward pressure on the tail of the forklift body to increase the stability of the forklift body and reduce the possibility of the forklift body tipping over during stacking.

[0012] The beneficial effects of the utility model are as follows:

[0013] 1. The utility model discloses an anti-tip device for a stacker, which is equipped with a first electric push cylinder to drive a second fixed rod and a universal wheel to move to the bottom of the container when the container is lifted, so as to provide support from the bottom. This can reduce the possibility that the stacker body may tip forward when driving due to the height and weight of the container, thereby increasing the safety and stability of the stacking.

[0014] 2. The utility model discloses an anti-dumping device for a stacker, which limits the height of container stacking by setting a second electric push cylinder to push the fourth fixed plate to a specified position, thereby controlling the height within a safe range, so as to reduce the possibility of the stacker body tipping over due to the container being lifted too high by the sling, thereby improving the safety of container stacking.

DETAILED DESCRIPTION

[0022] The following will be combined with the accompanying 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.

[0023] Specific examples are given below.

[0024] like Figures 1 to 3 As shown, an anti-dumping device for a stacker described in an embodiment of the present invention comprises a stacker body 1; a gantry 11 is connected to the end of the stacker body 1; a sling 12 is connected to the middle of the gantry 11; a first fixing plate 13 is fixedly connected to the bottom of the stacker body 1; a first electric push cylinder 14 is fixedly connected to the side wall of the first fixing plate 13; a second fixing rod 15 is fixedly connected to the end of the first electric push cylinder 14; a pair of universal wheels 16 are rotatably connected to the bottom of the second fixing rod 15; when working, when stacking containers, the stacker body 1 is opened to a suitable position, the gantry 11 is raised, and then the sling 12 is started to lift the container The container is lifted, and then the first electric push cylinder 14 is started to drive the second fixed rod 15 and the universal wheel 16 to move forward until the universal wheel 16 moves to the bottom of the container. When the stacker body 1 is traveling, the universal wheel 16 can be driven to move together. At this time, the stacker body 1 drives the container to the stacking position. This step is achieved by setting the first electric push cylinder 14 to drive the second fixed rod 15 and the universal wheel 16 to move to the bottom of the container when the container is lifted, so as to support it from the bottom, so as to reduce the situation where the stacker body 1 tipping forward when traveling due to the high height and heavy weight of the container, so as to increase the safety and stability of the stacking.

[0025] like Figure 2 As shown, the top of the gantry 11 is fixed with a third fixed plate 2; the bottom of the third fixed plate 2 is fixed with a second electric push cylinder 21; the end of the second electric push cylinder 21 is fixed with a fourth fixed plate 22; during operation, when the gantry 11 is raised, the second electric push cylinder 21 can be started to push downward, which can push the fourth fixed plate 22 downward and move the fourth fixed plate 22 to a specified position to limit the height of the container stacking. This step limits the height of the container stacking by setting the second electric push cylinder 21 to push the fourth fixed plate 22 to the specified position, thereby controlling the height within a safe range, so as to reduce the situation where the forklift body 1 may tip over due to the sling 12 lifting the container too high, so as to improve the safety when stacking the container.

[0026] like Figure 2 As shown, a plurality of sliding holes 3 are provided in the middle of the fourth fixing plate 22; a damping spring 31 is slidably connected in the sliding hole 3; during operation, when the sling 12 lifts the container and moves it upward, the top of the container will contact the end of the damping spring 31 when it approaches the fourth fixing plate 22. At this time, the top of the container will push the damping spring 31 upward to cause the damping spring 31 to contract and generate a buffering force. In this step, by setting the damping spring 31, the container can contact the top of the container when it approaches the fourth fixing plate 22, and contract to generate a buffering effect, thereby reducing the damage caused by the impact caused by direct contact between the top of the container and the fourth fixing plate 22.

[0027] like Figure 2 As shown, the end of the damping spring 31 is fixedly connected to a suction cup 4; the suction cup 4 is located at the bottom end of the damping spring 31; during operation, when the top of the container approaches the end of the damping spring 31, the suction cup 4 will contact the top of the container and be adsorbed at a position on the top that can fix the container. This step is to set the suction cup 4 to be adsorbed on the top of the container, which can play a fixing role when the container is stacked, thereby improving the position stability of the container during movement.

[0028] like Figure 2 As shown, a pair of protective covers 5 are detachably installed on the top of the fourth fixed plate 22; the protective covers 5 can cover the damping spring 31; during operation, the protective covers 5 are installed on the top of the fourth fixed plate 22 when stacking work is performed so that the protective covers 5 cover the damping spring 31. When the damping spring 31 needs to be maintained, the protective covers 5 can be removed. In this step, the damping spring 31 can be protected by setting the protective covers 5 to cover the damping spring 31 from the top of the fourth fixed plate 22, so as to reduce the corrosion of the damping spring 31 caused by dust and moisture in the air, resulting in a weakening of its function.

[0029] A counterweight box 6 is fixedly connected to the end of the stacker body 1; a plurality of counterweight blocks 61 are provided on the inner side wall of the counterweight box 6; during operation, the counterweight box 6 and the counterweight blocks 61 will press the stacker body 1 downward at the rear end of the stacker body 1 during stacking work. This step can increase the weight of the rear end of the stacker body 1 by providing the counterweight box 6 and the counterweight blocks 61. When the stacker body 1 is traveling, the counterweight box 6 and the counterweight blocks 61 exert downward pressure on the rear end of the stacker body 1 to increase the stability of the stacker body 1 and reduce the possibility of the stacker body 1 tipping over during stacking.

[0030] like Figure 2 As shown, the side wall is fixed with a rubber pad 7; during operation, when the spreader 12 lifts the container, the side wall of the container will contact the rubber pad 7. This step, by providing the rubber pad 7, can reduce the friction between the side wall of the container and the spreader 12 when the spreader 12 lifts the container, thereby reducing the possibility of damage.

[0031] Working principle: When working, when stacking containers, after the stacker body 1 is opened to the appropriate position, the gantry 11 is raised and the spreader 12 is started to lift the container, and then the first electric push cylinder 14 is started to drive the second fixed rod 15 and the universal wheel 16 to move forward until the universal wheel 16 moves to the bottom of the container. When the stacker body 1 is moving, the universal wheel 16 can be driven to move together. At this time, the stacker body 1 drives the container to the stacking position. When the gantry 11 is raised, the second electric push cylinder 21 can be started to push downward, which can push the fourth fixed plate 22 to move downward and move the fourth fixed plate 22 to the specified position to limit the height of the container stacking. When the spreader 12 lifts the container and moves it upward, the container When the top approaches the fourth fixed plate 22, it will contact the end of the damping spring 31. At this time, the top of the container will push the damping spring 31 upward to contract the damping spring 31 and generate a buffering force. When the top of the container approaches the end of the damping spring 31, the suction cup 4 will contact the top of the container and be adsorbed at the position on the top where the container can be fixed. When stacking, the protective cover 5 is installed on the top of the fourth fixed plate 22 so that the protective cover 5 covers the damping spring 31. When the damping spring 31 needs to be maintained, the protective cover 5 can be removed. When stacking, the counterweight box 6 and the counterweight block 61 will press the forklift body 1 downward at the tail of the forklift body 1. When the sling 12 lifts the container, the side wall of the container will contact the rubber pad 7.
