Description

Technical Field

[0001] The utility model relates to the technical field of tower crane anti-collision, in particular to an anti-collision warning device for construction tower cranes. Background Art

[0002] Tower cranes are indispensable auxiliary devices on construction sites. To ensure that tower crane fleets do not collide accidentally during use, anti-collision warning devices are needed for prevention. Generally, the self-cost, installation and maintenance costs of anti-collision warning devices are relatively high, and they are easily corroded by external factors after installation, resulting in reduced sensitivity and shortened service life of the anti-collision warning devices, further increasing the maintenance cost.

[0003] After retrieval, the Chinese document with the publication number of CN220664704U discloses an anti-collision warning device for tower cranes in construction. It includes: an installation base. Fixing holes are arranged at positions near the front and rear ends of the right surface of the installation base. The left end of the fixing hole penetrates through the protective installation base. A separation box body is slidably connected inside the storage groove of the installation base. Signal receivers and signal transmitters are respectively fixedly connected to the front and rear inner walls of the separation box body. A separation baffle is fixedly connected inside the separation box body, and the separation baffle is located between the signal receiver and the signal transmitter. A telescopic sealing baffle is fixedly connected to the upper inner wall of the separation box body near the box opening. When the warning device is in use, the lower surface of the telescopic sealing baffle is in close contact with the lower inner wall of the separation box body. Through the above device, it is convenient to install the anti-collision warning device, and at the same time, it ensures that important components inside the warning device are not affected by external factors. When the device is in use, due to the lack of a stable support component, when the tower crane boom structure swings at high altitude, it is easily affected by strong wind output, and at the same time, the internal parts are easily shaken when the boom swings, thus threatening the service life. In view of the above problems, an anti-collision warning device for construction tower cranes is provided here. Summary of the Utility Model

[0004] In order to make up for the above deficiencies, the utility model provides an anti-collision warning device for construction tower cranes, aiming to improve the problem that the lack of buffer protection for the overall structure in the prior art leads to the lack of stable support for internal parts.

[0005] To achieve the above object, the utility model adopts the following technical scheme: an anti-collision warning device for construction tower cranes, including two positioning plates. Mounting plates are installed on both sides of the back ends of the positioning plates. A top plate is installed between the positioning plates after installation. Buffer mechanisms are installed at both ends of the top plate. The buffer mechanisms are slidably connected to the inner sides of the positioning plates. A box body is installed at the bottom end of the top plate.

[0006] The buffer mechanism includes a buffer block. A buffer spring is installed at the inner top end of the positioning plate where the buffer block extends. The top end of the buffer spring passes through the positioning plate and is installed with a positioning bolt.

[0007] As a further description of the above technical solution:

[0008] An inner box body is installed inside the box body. Support mechanisms are installed on both sides of the inner top end of the inner box body. The support mechanism includes a support bottom plate. Damping springs are installed around the top of the support bottom plate. A support top plate is installed on the top of the damping springs. A distance sensor is installed on the top of the support top plate. The detection end of the distance sensor passes through the front surface of the box body.

[0009] As a further description of the above technical solution:

[0010] Partition boards are installed between the inner box bodies, and the partition boards are located above the distance sensors. A signal transmission device is installed on the top of the partition boards. The distance sensor is electrically connected to the signal transmission device.

[0011] As a further description of the above technical solution:

[0012] Reinforcement mechanisms are arranged through the four sides of the box body. The reinforcement mechanism includes an arc-shaped abutting head. Spring rods are installed on both sides of the back end of the arc-shaped abutting head. One end of the spring rod is telescopically connected to a barrel sleeve. One end of the barrel sleeve passes through the box body and is installed with a limit block, and the limit block is screwed to the barrel sleeve through a thread and fixed on one side of the box body.

[0017] The utility model has the following beneficial effects:

[0018] In the present utility model, a buffer mechanism is provided to enable buffer protection for the top plate structure inside the positioning plate. Meanwhile, the positioning plate is connected to the box body structure. When the positioning plate experiences amplitude fluctuations during the swinging of the boom or during use, the top plate drives the buffer block to slide inside the positioning plate. The buffer block squeezes the buffer spring during the overshoot of the movement, and the buffer spring is used to reduce the amplitude, thereby providing safety protection for the sensor structure inside the box body. At the same time, the damping spring equipped with a damper structure in the support mechanism is used to stably support the distance sensor.

Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all the embodiments. Based on the embodiments in the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present utility model.

[0026] Refer to Figures 1-4, an embodiment provided by the present utility model: a building tower crane anti-collision warning device, including two positioning plates 1, mounting plates 2 are installed on both sides of the back end of the positioning plate 1, a top plate 3 is installed between the positioning plates 1, buffer mechanisms 4 are installed at both ends of the top plate 3, the buffer mechanisms 4 are slidably connected to the inner side surface of the positioning plate 1, and a box body 5 is installed at the bottom end of the top plate 3;

[0027] The buffer mechanism 4 includes a buffer block 401, the buffer block 401 extends to the inner top end of the positioning plate 1 and a buffer spring 402 is installed, and the top end of the buffer spring 402 penetrates through the positioning plate 401 and a positioning bolt 403 is installed.

[0028] An inner box body 6 is installed inside the box body 5, support mechanisms 7 are installed on both sides of the inner top end of the inner box body 6, the support mechanism 7 includes a support bottom plate 701, damping springs 702 are installed around the top of the support bottom plate 701, a support top plate 703 is installed at the top of the damping springs 702, a distance sensor 8 is installed at the top of the support top plate 703, and the detection end of the distance sensor 8 penetrates through the front surface of the box body 5.

[0029] Partition plates 15 are installed between the inner box bodies 6, and the partition plates 15 are located above the distance sensor 8, a signal transmission device 14 is installed at the top of the partition plates 15, and the distance sensor 8 is electrically connected to the signal transmission device 14.

[0030] Reinforcement mechanisms 9 are arranged through the four sides of the box body 5, the reinforcement mechanism 9 includes an arc-shaped abutting head 901, spring rods 902 are installed on both sides of the back end of the arc-shaped abutting head 901, one end of the spring rod 902 is telescopically connected with a barrel sleeve 903, one end of the barrel sleeve 903 penetrates through the box body 5 and a limit block 904 is installed, and the limit block 904 is threadedly screwed to the barrel sleeve 903 and fixed to one side of the box body 5.

[0031] An alarm signal lamp 10 is installed at the top of the box body 5, and the signal transmission device 14 is electrically connected to the tower crane room alarm system and the alarm signal lamp 10 respectively.

[0032] A double-layer partition net 11 is arranged at the bottom end of the box body 5, a bottom plate 12 is installed at the bottom of the double-layer partition net 11, and a plurality of air holes 13 are opened at the front end of the bottom plate 12.

[0033] Specifically, the overall structure of this application is installed at the tower crane boom through the positioning plate 1 and the mounting plate 2. The top plate 3 can be fixedly connected to the box body 5 structure through external bolts. A reinforcement mechanism 9 is installed between the inner box body 6 and the box body 5. When the boom is operating, when the inner box body 6 receives the sway amplitude, the force can be applied to the spring rod 902 through the arc-shaped low joint 901, causing the spring rod 902 to retract into the inner part of the barrel sleeve 903. Thus, the spring structure in the spring rod 902 absorbs the amplitude energy, thereby reducing the sway amplitude of the inner box body 6. The distance sensor 8 and the signal transmission device 14 can be stored in the inner box body 6. The distance between different booms is monitored in real time by the distance sensor 8, and the detected signal is transmitted to the tower crane room through the signal transmission device 14 for real-time monitoring, which is used to remind the staff to control the distance between different booms and play the role of anti-collision warning for tower crane operation. The alarm signal lamp 10 is used to start the alarm signal lamp 10 by the signal transmission device 14 immediately to remind other tower crane staff nearby to take emergency avoidance. The support mechanism 7 can provide a stable support for the distance sensor 8 during operation. The support bottom plate 701 and the support top plate 703 are connected by the damping spring 702 of the damper structure to achieve good shock absorption work. At the same time, through the bottom grid 11, the internal environment of the inner box body 6 can be convected with the external air, and the air is discharged through the ventilation holes 13 in the bottom plate 12 to achieve a heat dissipation effect.

[0034] Working principle: When in use, the positioning plate 1 and the mounting plate 2 are fixedly installed at the tower crane boom through external bolts. The distance sensor 8 is placed inside the inner box body 6 and is supported by the support top plate 703. The signal transmission device 14 is placed at the partition plate 15. The distance sensor 8 and the signal transmission device 14 are started. The distance between different tower crane booms can be monitored in real time by the distance sensor 8. The detected data is received by the signal transmission device 14 and transmitted to the tower crane room and the alarm signal lamp 10 respectively. When the safe distance is exceeded, the alarm signal lamp 10 structure will be started to emit a flashing light and an alarm sound to warn other tower crane staff nearby to take emergency avoidance. During the swinging process of the boom, the buffer spring is compressed by the buffer block 401, causing the top plate 3 and the box body 5 to reduce the sway amplitude, thereby avoiding damage to internal parts. At the same time, the buffer spring 402 is fixed inside the positioning plate 1 through the positioning bolt 403. The damping spring 702 provides a stable support for the top distance sensor 8 to further enhance the stability performance of the distance sensor 8. When the external box body 5 structure sways horizontally, it drives the inner box body 6 to move. The inner box body 6 applies force to the spring rod 902 through the arc-shaped low joints 901 on both sides, causing the spring rod 902 to expand and contract in the barrel sleeve 903. Using the spring buffer performance, the sway amplitude of the inner box body 6 is reduced, thereby ensuring the overall stability performance of the warning device.
