DETAILED DESCRIPTION

[0023] The technical scheme in the embodiments of the utility model will be described clearly and completely in combination with the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, rather than all the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by those skilled in the art without creative labor are involved in the protection scope of the utility model.

[0024] Embodiment one:

[0025] Reference Figures 1-6The anti-collision device for tower crane cluster operation comprises at least four mounting plates 1 in "L" shape structure, and each mounting plate 1 is provided with a buffer mechanism on one side, the buffer mechanism comprises a buffer plate 101, a first connecting rod 102, a second connecting rod 103, buffer blocks 104 rotatably connected with both ends of the first connecting rod 102 and the second connecting rod 103 respectively, a first elastic element 105 arranged between the adjacent two buffer blocks 104, the mounting plate 1 and the buffer plate 101 are provided with buffer grooves 106 on the opposite sides, each buffer block 104 is arranged in the corresponding buffer groove 106 and is slidably connected with the inner wall of the buffer groove 106, the first connecting rod 102 is rotatably connected with the second connecting rod 103, and each mounting plate 1 is further provided with an adjusting assembly for adjusting the distance between the adjacent two mounting plates 1.

[0026] In use, the buffer plate 101 should be ensured to be located on both sides of the hoisting arm, then the distance between the mounting plates 1 is adjusted to the appropriate size of the hoisting arm of the tower crane through the adjusting assembly, and finally the mounting plate 1 is fixed. If the hoisting arm of the tower crane is collided, the buffer plate 101 will be forced to press down first, the first connecting rod 102 and the second connecting rod 103 will rotate, at the same time, the two ends of the first connecting rod 102 and the second connecting rod 103 drive the two buffer blocks 104 on the buffer plate 101 and the mounting plate 1 to move in the direction away from each other at the same time, so as to stretch the first elastic element 105. Since the first elastic element 105 always has the ability to restore deformation, it can pull the two buffer blocks 104 in the direction close to each other, thereby effectively unloading the impact force generated by the collision of the hoisting arm, reducing the damage caused by the collision to the hoisting arm, and further reducing the maintenance cost.

[0027] Secondly, the alarm assembly can be arranged on the side surface of the mounting plate 1, the alarm assembly comprises a distance sensor 5 and a buzzer arranged in the cab of the tower crane, and the distance sensor 5 is electrically connected with the buzzer. When the hoisting arm is about to collide with the object, the distance sensor 5 will first perceive and send an electric signal to the buzzer to trigger the buzzer to issue an alarm to remind the driver.

[0028] Further, the guiding rod 107 is fixedly connected in each buffer groove 106, and each buffer block 104 is slidably connected with the guiding rod 107. The guiding rod 107 arranged enhances the stability and accuracy of the movement of the buffer block 104 in the buffer groove 106, so that the buffer block 104 can only slide in the direction of the guiding rod 107, avoiding the deviation of the buffer block 104 in the movement process.

[0029] Secondly, the second elastic member 108 is arranged on both sides of the buffer groove 106, one end of the second elastic member 108 is fixedly connected with the buffer block 104, the other end of the second elastic member 108 is fixedly connected with the side surface of the buffer groove 106, and the second elastic member 108 and the first elastic member 105 are sleeved on the outer surface of the guide rod 107. The second elastic member 108 arranged together with the first elastic member 105 can provide stronger buffering force when the buffer block 104 is impacted. When the buffer block 104 moves to one side, the second elastic member 108 on one side is compressed, and the first elastic member 105 is stretched, which can work together with the first elastic member 105 to further improve the buffering performance of the anti-collision device and effectively reduce the impact damage of the tower crane.

[0030] In the embodiment, the adjusting assembly comprises an adjusting block 3 arranged on one side of the mounting plate 1, a fixed screw rod 301, and a rotating block 302. The other side of the mounting plate 1 is provided with a mounting groove 303. The adjusting block 3 is slidably connected with the inner wall of the mounting groove 303. One side of the mounting groove 303 is provided with an adjusting groove 304. The width of the adjusting groove 304 is greater than the diameter of the fixed screw rod 301. The fixed screw rod 301 is threadedly connected with the side of the adjusting block 3 close to the adjusting groove 304. The rotating block 302 is fixedly connected with one side of the fixed screw rod 301. The side of the rotating block 302 is in abutment with the side surface of the mounting plate 1.

[0031] When the size needs to be adjusted, the operator rotates the rotating block 302 to make it away from the surface of the mounting plate 1. Since the diameter of the fixed screw rod 301 is smaller than the width of the adjusting groove 304, the operator can freely move the adjusting block 3 in the mounting groove 303. After adjusting to the appropriate position, the operator rotates the rotating block 302 to drive the fixed screw rod 301 to rotate, so that the fixed screw rod 301 is screwed into the adjusting block 3 until the side of the rotating block 302 is in contact with the surface of the mounting plate 1. The position of the adjusting block 3 is fixed by the principle of friction. In addition, in order to enhance the fixing effect, a gasket 306 is arranged between the rotating block 302 and the mounting plate 1. The gasket 306 increases the contact area between the two, thereby improving the friction and further enhancing the fixing effect.

[0032] The adjusting assembly in the embodiment uses the principle of friction to fix the mounting plate 1, so that it can be fixed at any position in the adjusting groove 304. It is a continuous adjusting mode, thereby further improving the applicability and versatility of the anti-collision device.

[0033] Secondly, the cross section of the rotating block 302 is designed in a hexagonal shape, and a hexagonal groove 305 is arranged on the side of the rotating block 302 away from the fixed screw rod 301. The cross section of the rotating block 302 is hexagonal, which facilitates the rotation of the rotating block 302 by using a wrench or the like, and improves the convenience of adjustment and operation efficiency. The arrangement of the hexagonal groove 305 further increases the contact area and fitting degree of the rotating block 302 and the tool such as an internal hexagonal wrench, so that the rotation is more stable and reliable, and the slipping phenomenon is less likely to occur.

[0034] In addition, sliding grooves 4 are arranged on both sides of the mounting plate 1, and fixed plates 401 are slidably connected in the sliding grooves 4. One side of the fixed plate 401 extends to the outside of the sliding groove 4, and a mounting hole 402 is arranged on the side of the fixed plate 401 away from the sliding groove 4. Limiting rods 403 are fixedly connected in the sliding grooves 4, and the fixed plate 401 is slidably connected with the limiting rods 403. The mounting hole 402 is arranged on the fixed plate 401, and the fixed plate 401 can move, so that the position of the mounting hole 402 can be freely changed in the sliding groove 4, and the mounting hole 402 can be adapted to the position of the mounting hole 402 on the hoist jib of different types of tower cranes, and the staff can conveniently fix the mounting plate 1 and the hoist jib.

[0035] Embodiment two:

[0036] On the basis of the embodiment, with reference to Figure 4 In order to improve the structural strength of the buffer mechanism, a damping assembly is further arranged between the buffer plate 101 and the mounting plate 1. The damping assembly includes a support cylinder 2, a damping rod 201, and a third elastic member 202. The support cylinder 2 and the damping rod 201 are fixedly connected with the mounting plate 1 and the buffer block 104 on the buffer plate 101, respectively. The damping rod 201 is slidably connected with the inside of the support cylinder 2, and the third elastic member 202 is arranged in the inside of the support cylinder 2, and one end of the third elastic member 202 is fixedly connected with the damping rod 201.

[0037] The support cylinder 2 and the damping rod 201 are arranged on the buffer block 104, respectively, so that the first connecting rod 102 and the second connecting rod 103 form a triangular structure with the support cylinder 2 and the damping rod 201, so as to improve the overall structural strength and ensure that it can withstand a large impact force without being damaged. When the buffer plate 101 is impacted, the first connecting rod 102 and the second connecting rod 103 will rotate, and at the same time, the two ends of the first connecting rod 102 and the second connecting rod 103 drive the two buffer blocks 104 on the buffer plate 101 and the mounting plate 1 to move away from each other. At this time, the buffer plate 101 will move towards the mounting plate 1, and drive the damping rod 201 to slide along the inner wall of the support cylinder 2, and at the same time, compress the third elastic member 202, so as to further reduce the impact force generated by the collision of the tower crane, and reduce the damage degree of the hoist jib.
