Description

Technical Field

[0001] This utility model belongs to the field of crane technology, and in particular relates to a crane anti-collision device. Background Technology

[0002] Cranes are multi-action lifting machines that vertically lift and horizontally move heavy objects within a certain range. They are also called overhead cranes, gantry cranes, or hoists. According to their structural form, cranes are mainly divided into light and small lifting equipment (such as electric hoists), bridge cranes, gantry cranes, boom cranes, and cable cranes.

[0003] During operation, the hook of an existing crane is prone to swaying due to its high suspension. During this swaying, it may collide with the crane shell or other objects, causing damage to the objects or the crane itself. To address this, we have developed a crane anti-collision device. Utility Model Content

[0004] The purpose of this utility model is to provide a crane anti-collision device, which releases kinetic energy by compressing a spring to buffer the impact of the hook and connecting block, preventing the connecting block or hook from directly impacting the crane shell or objects, thus preventing damage to the objects or the crane shell. This solves the problem that in the operation of existing cranes, the hook part is prone to swaying due to its high suspension, and during the swaying process, it may collide with the crane shell or other objects, resulting in damage to the objects or the crane.

[0005] To solve the above-mentioned technical problems, this utility model is achieved through the following technical solution:

[0006] This utility model is a crane anti-collision device, including an anti-collision mechanism and connecting plates. The anti-collision mechanism is provided with an installation mechanism on its inner side. There are four connecting plates in total. A slider is slidably connected to one end of each connecting plate that is far apart from the other. There are two sliders in total. A spring is fixedly connected to one side of the two sliders that are close to each other. A connecting rod is rotatably connected to the right side of each slider. By compressing the spring, the kinetic energy is released, which completes the impact buffering of the hook and connecting block, preventing the connecting block or hook from directly hitting the crane shell or the object, causing damage to the object or the crane shell.

[0007] Furthermore, an impact plate is rotatably connected to the right side of the connecting rod, and a damping rod is fixedly connected to the right side of the connecting plate. The end of the damping rod away from the connecting plate is fixedly connected to the end of the impact plate near the connecting rod. A locking block is fixedly connected to the end of the connecting plate away from the slider. The connecting plate is installed by pushing the locking block into the slot inside the connecting block.

[0008] Furthermore, the installation mechanism includes a connecting block, the outer surface of which contacts a connecting plate, a hook fixedly connected to the bottom of the connecting block, a rotating groove inside the connecting block, a baffle rotatably connected to the inner wall of the rotating groove, and a slot inside the connecting block.

[0009] Furthermore, the inner wall of the slot is adapted to the outer surface of the block, and a fixed slot is provided inside the rotating slot. There are two fixed slots in total. A movable slot is provided inside the baffle. A push plate is engaged with the inner wall of the fixed slot located on the front. The outer surface of the push plate is adapted to the inner wall of the movable slot. When the push plate is aligned with the fixed slot, it falls downward by its own weight and enters part of the fixed slot, so that the push plate occupies both the fixed slot and the movable slot at the same time, and limits the position of the baffle.

[0010] This utility model has the following beneficial effects:

[0011] 1. This utility model, by setting an impact plate, specifically, when the impact plate comes into contact with the object, it will simultaneously compress the damping rod and the connecting rod. When the connecting rod is compressed, it will move inward along the connecting plate and compress the spring to release kinetic energy, thus completing the impact buffering of the hook and the connecting block, preventing the connecting block or the hook from directly impacting the crane shell or the object, causing damage to the object or the crane shell.

[0012] 2. This utility model uses a push plate. Specifically, the push plate is pushed upwards to disengage from the fixed groove and fully enter the movable groove. Then, the push plate is pushed counterclockwise, and the rotation of the push plate causes the baffle to rotate, thereby releasing the baffle from pressing the locking block. Then, the connecting plate is pushed upwards to move the locking block out of the slot, completing the replacement of the connecting plate. The operation is simple and the replacement can be completed quickly.

[0013] Of course, any product implementing this utility model does not necessarily need to achieve all of the advantages described above at the same time. Attached Figure Description

[0022] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of the present utility model.

[0023] Please see Figures 1-5 As shown, this utility model is a crane anti-collision device, including an anti-collision mechanism 2 and a connecting plate 201. An installation mechanism 1 is provided inside the anti-collision mechanism 2. There are four connecting plates 201 in total. A slider 202 is slidably connected to one end of the connecting plates 201 that is far apart from each other. There are two sliders 202 in total. A spring 206 is fixedly connected to one side of the two sliders 202 that are close to each other. A connecting rod 203 is rotatably connected to the right side of the slider 202. When the impact plate 204 comes into contact with the object, it will simultaneously squeeze the damping rod 205 and the connecting rod 203. When the connecting rod 203 is squeezed, it will move inward along the connecting plate 201 and squeeze the spring 206 to release kinetic energy, thereby completing the impact buffering of the hook 102 and the connecting block 101, preventing the connecting block 101 or the hook 102 from directly hitting the crane shell or the object, causing damage to the object or the crane shell.

[0024] The right side of the connecting rod 203 is rotatably connected to the impact plate 204, and the right side of the connecting plate 201 is fixedly connected to the damping rod 205.

[0025] The end of the damping rod 205 away from the connecting plate 201 is fixedly connected to the end of the impact plate 204 near the connecting rod 203, and the end of the connecting plate 201 away from the slider 202 is fixedly connected to the locking block 207.

[0026] The installation mechanism 1 includes a connecting block 101, the outer surface of which is in contact with the connecting plate 201, and a hook 102 is fixedly connected to the bottom of the connecting block 101.

[0027] The connecting block 101 has a rotating groove 104 inside, and a baffle 103 is rotatably connected to the inner wall of the rotating groove 104. The connecting block 101 also has a slot 105 inside.

[0028] The inner wall of the slot 105 is adapted to the outer surface of the block 207, and the rotating slot 104 has a fixed slot 107 inside.

[0029] There are two fixed slots 107. The baffle 103 has a movable slot 108 inside. The inner wall of the fixed slot 107 on the front is engaged with a push plate 106. The outer surface of the push plate 106 is adapted to the inner wall of the movable slot 108. Pushing the push plate 106 upward causes it to disengage from the fixed slot 107 and fully enter the movable slot 108. Then, push the push plate 106 counterclockwise. The rotation of the push plate 106 causes the baffle 103 to rotate, so that the baffle 103 releases the pressure on the locking block 207. Then, push the connecting plate 201 upward, causing the locking block 207 to move out of the slot 105, thus completing the replacement of the connecting plate 201. The operation is simple and the replacement can be completed quickly.

[0030] A specific application of this embodiment is as follows: When the crane lifts an object, the hook 102 and the connecting block 101 will sway. When a collision occurs, the impact plate 204 will be the first to contact the object. When the impact plate 204 contacts the object, it will simultaneously compress the damping rod 205 and the connecting rod 203. When the connecting rod 203 is compressed, it will move inward along the connecting plate 201 and compress the spring 206 to buffer the impact between the hook 102 and the connecting block 101, preventing the connecting block 101 or the hook 102 from directly impacting the outside of the crane. When the connecting plate 201 needs to be replaced on the shell or item, first push the push plate 106 upward so that the push plate 106 disengages from the fixed groove 107 and fully enters the movable groove 108. Then push the push plate 106 counterclockwise. Then, the circumferential rotation of the push plate 106 drives the baffle 103 to rotate, so that the baffle 103 releases the pressure on the locking block 207. Then push the connecting plate 201 upward so that it drives the locking block 207 to move out of the locking groove 105, thus completing the replacement of the connecting plate 201. The operation is simple and the replacement can be completed quickly.
