Description

Technical Field

[0001] This utility model belongs to the field of building construction technology, and in particular relates to a tower crane safety protection device. Background Technology

[0002] Tower cranes, also known as tower hoists, are rotating cranes with their jibs mounted on a tall tower. They offer a large working space and are primarily used for the vertical and horizontal transport of materials and the installation of building components in construction. A tower crane consists of three main parts: the metal structure, the working mechanism, and the electrical system. The metal structure includes the tower, the jib, and the base. The working mechanism comprises four parts: hoisting, luffing, slewing, and traveling. The electrical system includes motors, controllers, distribution cabinets, connecting lines, signaling, and lighting devices. In the construction industry, whether it's residential construction, commercial building construction, or large infrastructure construction such as bridges, tower cranes are essential for transporting building materials such as steel bars, concrete, and precast components.

[0003] During operation, the hook and boom of a tower crane descend to the ground via a hoisting rope to lift items. The boom is prone to swaying during movement, especially in windy conditions. This can easily cause the boom to collide with surrounding buildings or workers, resulting in safety accidents, causing great harm, and damaging the equipment. Utility Model Content

[0026] To make the objectives, technical solutions, and advantages of this utility model clearer, the following detailed description is provided with reference to the accompanying drawings and preferred embodiments. However, it should be noted that many details listed in the specification are merely to provide the reader with a thorough understanding of one or more aspects of this utility model, and these aspects can be achieved even without these specific details.

[0027] like Figure 1-6As shown, a tower crane safety protection device includes a hook body 1, an installation mechanism 2, and a buffer mechanism 3. Two installation mechanisms 2 are provided, each detachably mounted on one of the two clamping plates 11 of the hook body 1. The buffer mechanisms 3 are respectively provided on each installation mechanism 2 and include a connecting cylinder 31, a buffer spring 32, a crash plate 33, and a buffer plate 34. The connecting cylinder 31 is hollow inside, with an opening at one end away from the clamping plate 11. Multiple connecting cylinders 31 are horizontally arranged front and back, respectively distributed in a rectangular pattern on the installation mechanism 2. The crash plate 33 is vertically arranged. The buffer spring 32 is horizontally arranged front and back, with one end fixedly connected to the inside of the connecting cylinder 31 and the other end fixedly connected to the side of the crash plate 33 near the clamping plate 11. The connecting cylinder 31 provides a fixed installation position for the buffer spring 32, allowing it to be installed in a... The buffer plate 32 extends and retracts in a stable direction. When the anti-collision plate 33 is subjected to a collision force, the connecting cylinder 31 can limit the deformation direction of the buffer spring 32, preventing the spring from being excessively twisted or displaced, thereby ensuring that the buffer mechanism 3 can function effectively. When the hook collides, the impact force compresses the buffer spring 32, storing the collision energy as elastic potential energy, preventing all the impact force from acting on the hook and other components, reducing the harm caused by the collision accident, and reducing the damage to the hook body 1. The buffer plate 34 is fixedly installed on the side of the anti-collision plate 33 away from the clamping plate 11. The buffer plate 34 is made of a material with certain elasticity or buffering properties. When in contact with the colliding object, it can deform to a certain extent, thereby absorbing part of the impact force. At the same time, the presence of the buffer plate 34 can also protect the anti-collision plate 33 and internal components such as the buffer spring 32.

[0028] The installation mechanism 2 includes an installation plate 21, connectors 22, snap-fit ​​components 23, and locking components 24. The installation plate 21 is vertically arranged with through openings 211 on both its left and right sides. The connectors 22 are horizontally arranged in the openings 211 and can slide within them. For hook body 1 clamping plates 11 of different lengths, the connectors 22 can slide within the openings 211 of the installation plate 21, allowing the connectors 22 on both sides to extend or shorten towards the sides of the installation plate 21, thus adapting to clamping plates 11 of different lengths and improving applicability. The snap-fit ​​components 23 are vertically arranged in the mounting plate 21. On the side of component 22 away from mounting plate 21, a vertically extending slot 231 is provided on the side facing mounting plate 21. The slot 231 engages with both sides of the clamping plate 11 of hook body 1, thereby fixing the installation mechanism 2 on the clamping plate 11. The locking component 24 is vertically arranged on the side of connector 22 away from clamping plate 11 and is fixedly connected to the side of connector 22 close to mounting plate 21. The two locking components 24 can lock each other. By locking the two locking components 24 together, the slot 231 of the engaging component 23 is securely locked on both sides of clamping plate 11, thereby locking the installation mechanism 2 on clamping plate 11.

[0029] In a further embodiment, the snap-fit ​​member 23 is provided with a buffer pad on the side away from the clamping plate 11 to reduce the damage to the installation mechanism 2 when the side of the hook body 1 is hit.

[0030] The connecting cylinders 31 are respectively fixed above and below the openings 211 on both sides of the mounting plate 21. Multiple connecting cylinders 31 and buffer springs 32 can effectively provide shock absorption and cushioning.

[0031] The mounting plate 21 has vertically positioned limiting rods 25 in the center of the openings 211 on both sides; the connector 22 has vertically penetrating grooves 221 on its top and bottom surfaces, through which the connector 22 is fitted onto the limiting rods 25. The limiting rods 25 are used to prevent the connector 22 from falling out of the openings 211.

[0032] In another embodiment, the top and bottom surfaces of the opening 211 of the mounting plate 21 are provided with grooves 212, and the top and bottom surfaces of the connector 22 are provided with sliders 222 that cooperate with the grooves 212. The connector 22 moves in the grooves 212 through the sliders 222, which can ensure the smooth sliding of the connector 22 and prevent the connector 22 from falling off.

[0033] The upper and lower ends of the locking member 24 extend out from the top and bottom surfaces of the anti-collision plate 33, respectively. Both the upper and lower parts of the locking member 24 have through-holes. The extended ends of the locking member 24 facilitate the connection and locking operation of two locking members 24.

[0034] It also includes bolts 26; the bolts 26 pass through the connecting holes of the two locking members 24 to connect the two locking members 24. By passing the bolts 26 through the connecting holes of the two locking members 24, the two locking members 24 can be securely connected to each other, ensuring the connection stability between the mounting mechanism 2 and the clamping plate 11.

[0035] The working principle of this utility model is as follows:

[0036] First, move the connector 22 to both sides of the mounting plate 21 so that the snap-fit ​​23 extends out of the clamping plate 11 to both sides. Then, move the connector 22 inward according to the length of the clamping plate 11 of the hook body 1 so that the snap-fit ​​groove 231 of the snap-fit ​​23 locks the clamping plate 11 to both sides. Finally, use bolts 26 to pass through the connecting holes at the upper and lower ends of the two locking parts 24 to lock the locking parts 24. At this time, the snap-fit ​​23 can be firmly locked on the clamping plate 11, and the installation is completed.

[0037] When the tower crane is carrying out hoisting operations, if a collision occurs, the buffer plate 34, anti-collision plate 33 and buffer spring 32 of the buffer mechanism 3 will provide shock absorption and buffering, reduce the severity of the collision accident and reduce damage to the hook body.

[0038] The above description is only a preferred embodiment of the present utility model. It should be noted that for those skilled in the art, several improvements and modifications can be made without departing from the principle of the present utility model, and these improvements and modifications should also be considered within the protection scope of the present utility model.
