Description

Technical Field

[0001] This utility model relates to the field of building technology, and in particular to an integrated tower crane counterweight boom slewing assembly. Background Technology

[0002] The jacking of a tower crane refers to raising the lower support of the slewing assembly relative to the tower body to a certain height, then moving the standard section below the lower support and fixing the standard section to the lower support and the tower body.

[0003] The existing integrated tower crane counterweight slewing assembly has poor guiding performance during the docking process. When docking the lower support with the standard section, it often requires repeated manual adjustments, which not only increases the workload of operators but also leads to low docking efficiency and prolongs the installation or maintenance time of the tower crane. Moreover, misalignment and other issues are prone to occur during docking, affecting the accuracy and stability of subsequent connections. Utility Model Content

[0004] To solve the above-mentioned technical problems, this utility model provides an integrated tower crane counterweight boom slewing assembly.

[0005] This utility model is achieved by the following technical solution: an integrated tower crane balance boom slewing assembly, including a lower support, a standard section is inserted and connected to the bottom of the lower support, guide mechanisms are provided on the left and right sides of the lower support, and insertion mechanisms are provided at the front and rear ends of the lower support.

[0006] The guiding mechanism includes a connecting rod, a spring fixedly connected inside the connecting rod, a telescopic rod fixedly connected to one end of the spring, a guide rod fixedly connected to the bottom of the telescopic rod, support frames fixedly connected to both sides of the standard section, and a guide cone fixedly connected to the top of the support frame.

[0007] The above technical solution features a hollow guide cone with a larger top and smaller bottom. A support frame is fixed to both sides of the standard section, its top connected to the guide cone, providing support and fixation to ensure the guide cone's stable position during docking and its proper guiding function. A spring is located inside the connecting rod, with one end fixedly connected to the connecting rod and the other end fixedly connected to the telescopic rod. During the guiding process, when the telescopic rod retracts, the spring is compressed and generates elastic force, causing the guide rod to tightly conform to the inner wall of the guide cone, ensuring guiding accuracy. Simultaneously, it assists the telescopic rod in resetting upon completion of docking or when separation is required.

[0008] As a further improvement to the above solution, two connecting rods are provided, located on the left and right sides of the lower support, with one end of each connecting rod fixedly connected to one side of the lower support.

[0009] As a further improvement to the above solution, the inner wall of the connecting rod is slidably connected to the surface of the telescopic rod, and the guide rod is inserted into the guide cone.

[0010] As a further improvement to the above solution, the insertion mechanism includes a fixed cone, and a fixed cylinder is inserted and connected to the surface of the fixed cone.

[0011] As a further improvement to the above scheme, the number of fixed cones is set to four, the fixed cones are located at the front and rear ends of the standard section, and one end of the fixed cone is fixedly connected to the front and rear ends of the standard section.

[0012] With the above technical solution, the fixed cone is located at the front and rear ends of the standard section and is fixedly connected to the standard section. During docking, it is inserted into the fixed cylinder. Through the cooperation with the fixed cylinder, the lower support and the standard section are fixed from the front and rear directions, which enhances the firmness of the connection between the two.

[0013] As a further improvement to the above solution, the surface of the fixed cylinder is fixedly connected to the front and rear ends of the lower support.

[0014] As a further improvement to the above scheme, the number of fixed cylinders is set to correspond to the number of fixed cones.

[0015] Through the above technical solution, the surface of the fixed cylinder is fixedly connected to the front and rear ends of the lower support, and the number of cylinders corresponds to that of the fixed cones, for insertion into the fixed cones. It provides an insertion channel and fixed position for the fixed cones, and works with the fixed cones to achieve a firm connection between the lower support and the standard section, restricting the relative movement between the two.

[0016] Compared with the prior art, the beneficial effects of this utility model are as follows:

[0017] This invention utilizes a guide rod and a guide cone. The guide rod, in conjunction with a telescopic rod and a spring, is inserted into the hollow structure of the guide cone, which is wider at the top and narrower at the bottom, to achieve initial guidance and positioning. The sliding connection between the connecting rod and the telescopic rod ensures a smooth guiding process. This provides precise initial guidance for the docking of the lower support and the standard section, making the docking process smoother, reducing adjustment time during docking, and greatly improving docking efficiency.

[0018] This utility model, by setting a fixed cone and a fixed cylinder, first inserts the bottom of the lower support and the standard section, and then the fixed cones at the front and rear ends of the standard section are precisely inserted into the corresponding fixed cylinders at the front and rear ends of the lower support, thus completing the firm connection between the lower support and the standard section. This enhances the stability and firmness of the connection between the lower support and the standard section, and ensures the reliable operation of the slewing assembly during the working process.

[0026] The present invention will be further described below with reference to the accompanying drawings and specific embodiments. It should be noted that, without conflict, the various embodiments or technical features described below can be arbitrarily combined to form new embodiments.

[0027] Example:

[0028] Please combine Figure 1-5 An integrated tower crane counterweight slewing assembly according to this embodiment includes a lower support 1, a standard section 2 is inserted and connected to the bottom of the lower support 1, guide mechanisms 3 are provided on the left and right sides of the lower support 1, and insertion mechanisms 4 are provided at the front and rear ends of the lower support 1.

[0029] The guiding mechanism 3 includes a connecting rod 31, with a spring 32 fixedly connected inside the connecting rod 31. One end of the spring 32 is fixedly connected to a telescopic rod 33, and the bottom of the telescopic rod 34 is fixedly connected to a guide rod 34. Support frames 35 are fixedly connected to both sides of the standard section 2, and a guide cone 36 is fixedly connected to the top of the support frame 35. When the lower support 1 and the standard section 2 begin to align, the guide rod 34 first contacts the larger opening at the top of the guide cone 36. Due to the special design of the guide cone 36—large at the top, small at the bottom, and hollow—it generates a guiding force that converges towards the center on the guide rod 34. At this time, the spring 32 is in its natural state, and part of the telescopic rod 33 extends out of the connecting rod 31. As the lower support 1 approaches the standard section 2, the guide rod 34 gradually moves downward along the inner wall of the guide cone 36. The squeezing force generated by the inner wall of the guide cone 36 on the guide rod 34 is transmitted to the telescopic rod 33, causing the telescopic rod 33 to contract inward towards the connecting rod 31, while simultaneously compressing the spring 32. When spring 32 is compressed, it generates a reverse elastic force. This elastic force acts on the telescopic rod 33, ensuring that the guide rod 34 remains tightly fitted against the inner wall of the guide cone 36. This guarantees the accuracy of the guiding process and prevents deviation caused by the guide rod 34 detaching from the inner wall of the guide cone 36. Meanwhile, the inner wall of the connecting rod 31 maintains a sliding connection with the surface of the telescopic rod 33, allowing for smooth movement within the connecting rod 31. This ensures that the guide rod 34 can smoothly and gradually penetrate the structure of the guide cone 36, ultimately achieving initial guiding and positioning when the lower support 1 aligns with the standard section 2.

[0030] There are two connecting rods 31, which are located on the left and right sides of the lower support 1. One end of each connecting rod 31 is fixedly connected to one side of the lower support 1.

[0031] The inner wall of the connecting rod 31 is slidably connected to the surface of the telescopic rod 33, and the guide rod 34 is inserted into the guide cone 36.

[0032] The insertion mechanism 4 includes a fixed cone 41, and a fixed cylinder 42 is inserted and connected to the surface of the fixed cone 41. Then, the bottom of the lower support 1 and the standard section 2 are inserted first. After that, the fixed cones 41 at the front and rear ends of the standard section 2 are precisely inserted into the corresponding fixed cylinders 42 at the front and rear ends of the lower support 1, thus completing the firm connection between the lower support 1 and the standard section 2, thereby realizing the stable assembly and operation of the entire rotary assembly.

[0033] There are four fixed cones 41. The fixed cones 41 are located at the front and rear ends of the standard section 2, and one end of the fixed cone 41 is fixedly connected to the front and rear ends of the standard section 2.

[0034] The surface of the fixed cylinder 42 is fixedly connected to the front and rear ends of the lower support 1.

[0035] The number of fixed cylinders 42 corresponds to the number of fixed cones 41.

[0036] The implementation principle of an integrated tower crane counterweight slewing assembly in this embodiment is as follows: When the lower support 1 and the standard section 2 begin to connect, the guide rod 34 first contacts the larger opening at the top of the guide cone 36. Due to the special design of the guide cone 36—large at the top, small at the bottom, and hollow—it generates a guiding force that converges towards the center on the guide rod 34. At this time, the spring 32 is in its natural state, and the telescopic rod 33 partially extends out of the connecting rod 31. As the lower support 1 approaches the standard section 2, the guide rod 34 gradually moves downward along the inner wall of the guide cone 36. The squeezing force generated by the inner wall of the guide cone 36 on the guide rod 34 is transmitted to the telescopic rod 33, causing the telescopic rod 33 to contract inward toward the connecting rod 31, while simultaneously compressing the spring 32. When the spring 32 is compressed, it generates a reverse elastic force. This elastic force acts on the telescopic rod 33, ensuring that the guide rod 34 always fits tightly against the inner wall of the guide cone 36, guaranteeing the accuracy of the guiding process and preventing deviation caused by the guide rod 34 detaching from the inner wall of the guide cone 36. The inner wall of the connecting rod 31 maintains a sliding connection with the surface of the telescopic rod 33, allowing for smooth movement within the connecting rod 31. This ensures that the guide rod 34 can gradually penetrate deeper along the structure of the guide cone 36, ultimately achieving initial guidance and positioning when the lower support 1 and the standard section 2 are docked. Subsequently, the bottom of the lower support 1 and the standard section 2 are first inserted together. Then, the fixing cones 41 at the front and rear ends of the standard section 2 are precisely inserted into the corresponding fixing cylinders 42 at the front and rear ends of the lower support 1, completing the firm connection between the lower support 1 and the standard section 2, thereby achieving stable assembly and operation of the entire rotary assembly.

[0037] The above embodiments are merely preferred embodiments of this utility model and should not be construed as limiting the scope of protection of this utility model. Any non-substantial changes and substitutions made by those skilled in the art based on this utility model shall fall within the scope of protection claimed by this utility model.
