Description

Technical Field

[0001] This utility model relates to the technical field of tower crane connectors, specifically a modular tower crane connector. Background Technology

[0002] Tower crane connectors are key components used to connect the various parts of a tower crane.

[0003] Chinese Patent No. 201520306295.5 discloses a forming connector for a tower crane. The forming connector includes a tooling frame (1), with single ear plates (2) welded to the upper end faces of the four corners of the tooling frame (1). The single ear plates (2) are provided with pins (3) and positioning sleeves (4). Positioning pins (5) are set at the upper center of the four corners of the tooling frame (1). Double ear plates (6) are welded to the lower end faces of the four corners of the tooling frame (1). The double ear plates (6) are also provided with pins and positioning sleeves.

[0004] This invention has poor shock absorption, and vibration is unavoidable during use, affecting the stability of the tower crane. Utility Model Content

[0005] The purpose of this invention is to provide a modular tower crane connector to solve the problems raised in the prior art.

[0006] To achieve the above objectives, this utility model provides the following technical solution: a modular tower crane connector, comprising a connector and a connecting bracket; the connector consists of a mounting plate and a mounting cylinder, a shock-absorbing mechanism is installed between the mounting plates, a limiting mechanism is installed at the middle position between the mounting plates, the mounting cylinder is installed on one side of the mounting plate, slots are provided around the upper end of the mounting cylinder, one end of the connecting bracket is inserted into the mounting cylinder, a baffle is welded to the upper side of the connecting bracket, a threaded rod is welded around one end of the connecting bracket, the threaded rod is embedded in the slot, and a nut is rotatably installed on the outer side of the threaded rod.

[0007] Preferably, a triangular stake is provided between the mounting cylinder and the mounting plate, and the triangular stake is welded to the outside of the mounting cylinder and one side of the mounting plate.

[0008] Preferably, the upper end of the slot is tapered, with the larger diameter end facing upwards.

[0009] Preferably, the damping mechanism consists of a damping spring and a damper, with the upper and lower ends of the damper installed between the mounting plates, and the damping spring installed between the mounting plates on the outside of the damper.

[0010] Preferably, a protective sleeve is provided between the mounting plates, and the protective sleeve is attached between the mounting plates by adhesive.

[0011] Preferably, the limiting mechanism consists of a lower limiting rod and a sliding groove. The sliding groove is installed on the upper side of the mounting plate at the bottom of the connector, and the limiting rod is installed on the bottom of the mounting plate at the upper end of the connector. The bottom end of the limiting rod is slidably installed inside the sliding groove.

[0012] Compared with the prior art, the beneficial effects of this utility model are:

[0013] 1. The vibration damping mechanism installed between the mounting plates can effectively absorb and buffer the vibrations generated during the operation of the tower crane. When the tower crane is subjected to vibration impact, the vibration damping mechanism takes effect first, reducing the impact of vibration on the overall structure of the connecting parts; at the same time, the limiting mechanism at the middle position between the mounting plates can limit the relative displacement between the mounting plates, ensuring the stability of the connecting parts structure;

[0014] 2. During the insertion of the threaded rod on the connecting bracket into the slot, the larger diameter of the slot makes it easier to align with the slot, reducing installation difficulty and improving installation efficiency. Simultaneously, as the threaded rod gradually inserts into the slot, the smaller diameter allows for a tighter fit between the threaded rod and the slot, further enhancing the reliability of the connection between the connecting bracket and the mounting cylinder, ensuring that the connection points of the modular tower crane will not easily loosen during operation.

[0015] 3. When the tower crane vibrates, the dampers, installed between the upper and lower ends of the mounting plate, can quickly dissipate vibration energy and suppress the rapid transmission and amplification of vibration. The damping springs installed on the outside of the dampers absorb part of the vibration energy through their own elastic deformation, converting mechanical energy into elastic potential energy, thus playing a role in buffering and damping. The two work together to effectively reduce the impact of tower crane vibration on connecting parts and other components, reduce wear caused by vibration, and extend the service life of the modular tower crane.

[0016] 4. When the mounting plate is subjected to external force, the limiting rod slides in the slide groove. Through the cooperation between the limiting rod and the slide groove, the movement of the mounting plate is restricted within a certain range, avoiding excessive displacement or misalignment of the mounting plate, thereby ensuring the stability of the connecting structure and enabling the various components of the modular tower crane to work normally and collaboratively.

[0023] 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 of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0024] Please see Figure 1 , Figure 2 , Figure 3 , Figure 4 In this embodiment of the utility model, a modular tower crane connector includes a connector 1 and a connecting bracket 8. The connector 1 consists of a mounting plate 2 and a mounting cylinder 5. A shock-absorbing mechanism 16 is installed between the mounting plates 2, and a limiting mechanism 4 is installed in the middle between the mounting plates 2. The mounting cylinder 5 is installed on one side of the mounting plate 2, and slots 6 are provided around the upper end of the mounting cylinder 5. One end of the connecting bracket 8 is inserted into the mounting cylinder 5, and a baffle 9 is welded to the upper side of the connecting bracket 8. A threaded rod 10 is welded around one end of the connecting bracket 8, and the threaded rod 10 is embedded in the slot 6. A nut is rotatably installed on the outside of the threaded rod 10. A triangular stake 3 is provided between the mounting cylinder 5 and the mounting plate 2. The triangular stake 3 is welded to the outside of the mounting cylinder 5 and one side of the mounting plate 2. When the tower crane is subjected to lateral, longitudinal, or oblique forces, the triangular stake 3 can effectively disperse and transmit these forces, preventing loosening or deformation between the mounting cylinder 5 and the mounting plate 2, ensuring the stability of the overall structure of the connector 1, and thus improving the safety of the modular tower crane operation.

[0025] The upper end of slot 6 is tapered, with the larger diameter end facing upwards. During insertion of the threaded rod 10 on the connecting bracket 8 into slot 6, the larger diameter of the upper end of slot 6 makes alignment easier, reducing installation difficulty and improving efficiency. Simultaneously, as the threaded rod 10 gradually inserts into slot 6, the decreasing diameter ensures a tighter fit between the threaded rod 10 and slot 6, further enhancing the reliability of the connection between the connecting bracket 8 and the mounting cylinder 5, ensuring that the connection will not easily loosen during operation of the modular tower crane.

[0026] The vibration damping mechanism 16 consists of a damping spring 14 and a damper 15. The upper and lower ends of the damper 15 are installed between the mounting plates 2, while the damping spring 14 is installed between the mounting plates 2 on the outside of the damper 15. When the tower crane vibrates, the damper 15, installed between the upper and lower ends of the mounting plates 2, can quickly dissipate the vibration energy and suppress the rapid transmission and amplification of the vibration. The damping spring 14, installed on the outside of the damper 15, absorbs part of the vibration energy through its own elastic deformation, converting mechanical energy into elastic potential energy, thus playing a role in buffering and damping. The two work together to effectively reduce the impact of tower crane vibration on the connecting parts 1 and other components, reduce wear caused by vibration, and extend the service life of the modular tower crane.

[0027] A protective sleeve 7 is provided between the mounting plates 2. The protective sleeve 7 is attached between the mounting plates 2 with adhesive. The protective sleeve 7 is provided to protect the shock absorption mechanism 16 and the limiting mechanism 4, so as to prevent external dust and moisture from corroding the shock absorption mechanism 16 and the limiting mechanism 4 during use, and to extend the service life of the shock absorption mechanism 16 and the limiting mechanism 4.

[0028] The limiting mechanism 4 consists of a lower limiting rod 13 and a sliding groove 12. The sliding groove 12 is installed on the upper side of the mounting plate 2 at the bottom of the connector 1, and the limiting rod 13 is installed on the bottom of the mounting plate 2 at the upper end of the connector 1. The bottom end of the limiting rod 13 is slidably installed inside the sliding groove 12. When the mounting plate 2 is subjected to external force, the limiting rod 13 slides in the sliding groove 12. Through the cooperation of the limiting rod 13 and the sliding groove 12, the movement of the mounting plate 2 is restricted within a certain range, so as to avoid excessive displacement or misalignment of the mounting plate 2, thereby ensuring the stability of the connector 1 structure and enabling the various components of the modular tower crane to work normally and collaboratively.

[0029] The working principle and usage process of this utility model: During operation, the tower crane will be subjected to various complex external forces, such as the tension when lifting heavy objects and wind force. The shock absorption mechanism 16 installed between the mounting plates 2 can effectively absorb and buffer the vibration generated during the operation of the tower crane. When the tower crane is subjected to vibration impact, the shock absorption mechanism 16 will take effect first to reduce the impact of vibration on the overall structure of the connecting part 1; at the same time, the limiting mechanism 4 in the middle position between the mounting plates 2 can limit the relative displacement between the mounting plates 2, ensuring the stability of the connecting part 1 structure. The mounting cylinder 5 is installed on one side of the mounting plate 2, and the slots 6 around its upper end cooperate with the connecting bracket 8. One end of the connecting bracket 8 is inserted into the mounting cylinder 5. The baffle 9 can increase the contact area between the bracket and the mounting cylinder 5. After the threaded rod 10 is embedded in the slot 6, the connecting bracket 8 is firmly fixed in the mounting cylinder 5 by rotating the nut, realizing the reliable connection between the connecting part 1 and the connecting bracket 8, and ensuring the stable connection and coordinated operation between the various components of the modular tower crane.

[0030] Finally, it should be noted that the above are merely preferred embodiments of this utility model and are not intended to limit the utility model. Although the utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features.
