Description

Technical Field

[0001] This application relates to the field of counterbalance arm technology, and more specifically, to a counterbalance arm tie rod connector. Background Technology

[0002] Tower cranes are crucial and common large-scale vertical conveying equipment on construction sites. Depending on the luffing mechanism, tower cranes can be divided into two types: horizontal luffing tower cranes and luffing jib tower cranes. The structure of a horizontal luffing tower crane typically includes a tower body, a slewing support mounted on top of the tower body, and a tower top mounted on the slewing support. The tower top is where the jib, counterweight jib, and lifting mechanism are installed.

[0003] In existing technologies, connectors are mostly fixed with bolts, which is troublesome and time-consuming when workers need to perform regular maintenance or installation.

[0004] Therefore, a balance arm tie rod connector is provided. Utility Model Content

[0005] To address the shortcomings of existing technologies, this utility model provides a balance arm tie rod connector, solving the problems mentioned in the background section. To achieve the above objectives, this utility model is implemented through the following technical solution: A balance arm tie rod connector includes a first connector and a second connector. An installation assembly is mounted on the first and second connectors. The installation assembly includes a first mounting cylinder, which is fixedly connected to the right side of the first connector. An L-shaped groove is formed on the outer side of the first mounting cylinder. A spring is installed inside the first mounting cylinder, and a disc is slidably connected inside the first mounting cylinder. A second mounting cylinder is fixedly connected to the left side of the second connector. A hydraulic cylinder is fixedly connected inside the second mounting cylinder. One end of the hydraulic cylinder is slidably connected to a force-bearing rod via a piston, and the other end of the hydraulic cylinder is slidably connected to a pressure rod via a piston. A fixing rod is fixedly connected to the extended end of the pressure rod.

[0006] Preferably, the disk is located on the motion trajectory of the force-bearing rod.

[0007] Preferably, the interior of the second mounting cylinder has a circular groove for the movement of the fixing rod.

[0008] Preferably, the diameter of the first mounting cylinder is larger than the diameter of the second mounting cylinder.

[0009] Preferably, the first connector and the second connector are equipped with reinforcement components for secondary fixation of the first connector and the second connector.

[0010] Preferably, the reinforcement component includes a first fixing plate, which is fixedly connected to the outside of the second mounting cylinder. A spring rod is elastically connected to the side of the first fixing plate. A second fixing plate is fixedly connected to the outside of the first mounting cylinder. A through groove is provided on the second fixing plate. A support plate is fixedly connected to the top of the first mounting cylinder. A miniature electric telescopic rod is fixedly connected through the inside of the support plate. A compression plate is slidably connected to the outside of the first mounting cylinder.

[0011] Preferably, there are two sets of spring rods and two sets of through slots.

[0012] The advantages of this application are:

[0013] I. This application sets up a first mounting cylinder and a second mounting cylinder, so that the second mounting cylinder is close to the first mounting cylinder. The force rod is subjected to the squeezing force, which can push out the pressure rod, and then push out the fixing rod, so that the fixing rod can be engaged and fixed with the L-shaped slot. This solves the problem mentioned in the background art that the connectors are mostly fixed by bolts, which is troublesome and time-consuming when workers need to perform regular maintenance or installation.

[0014] Second, by setting a fixed plate, this application allows the two sets of spring rods to be elastically compressed, and then rotated to enter the interior of the two sets of through slots, thereby solving the problem in the background art that the first connector and the second connector may detach under accidental circumstances, and therefore require further reinforcement.

[0022] To enable those skilled in the art to better understand the present application, the technical solutions in the embodiments of the present application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are merely some, not all, of the embodiments of the present application. All other embodiments obtained by those skilled in the art based on the embodiments of the present application without creative effort should fall within the scope of protection of the present application.

[0023] It should be noted that, unless otherwise specified, the embodiments and features described in this application can be combined with each other. This application will now be described in detail with reference to the accompanying drawings and embodiments.

[0024] Example 1

[0025] See Figures 1-4 This embodiment provides a balance arm tie rod connector, including a first connector 1 and a second connector 2. An installation assembly 3 is mounted on the first connector 1 and the second connector 2. The installation assembly 3 includes a first mounting cylinder 301, which is fixedly connected to the right side of the first connector 1. An L-shaped groove 309 is provided on the outer side of the first mounting cylinder 301. A spring 303 is installed inside the first mounting cylinder 301, and a disc 302 is slidably connected inside the first mounting cylinder 301. A second mounting rod is fixedly connected to the left side of the second connector 2. The second mounting cylinder 304 has a hydraulic cylinder 306 fixedly connected inside. One end of the hydraulic cylinder 306 is slidably connected to a force rod 307 via a piston, and the other end of the hydraulic cylinder 306 is slidably connected to a pressure rod 308 via a piston. The extended end of the pressure rod 308 is fixedly connected to a fixing rod 305. The disc 302 is located on the movement trajectory of the force rod 307. The second mounting cylinder 304 has a circular slot for the movement of the fixing rod 305. The diameter of the first mounting cylinder 301 is larger than the diameter of the second mounting cylinder 304.

[0026] In practical use, the above-mentioned device first moves the second connecting member 2 towards the second mounting cylinder 304 towards the first mounting cylinder 301. At this time, the force rod 307 is squeezed by the disc 302, and the spring 303 is also elastically compressed. When the force rod 307 is squeezed, the liquid pressure inside the hydraulic cylinder 306 increases, which pushes out the pressure rod 308. When the pressure rod 308 is pushed out, it can drive the fixing rod 305 out. When the fixing rod 305 is pushed out, it continues to move towards the inside of the first mounting cylinder 301 and then rotates, so that the fixing rod 305 is engaged and fixed with the L-shaped slot 309. This solves the problem that in the prior art, most connecting members are fixed by bolts, which is troublesome and time-consuming when workers need to perform regular maintenance or installation.

[0027] Example 2

[0028] See Figures 1-4 Based on Embodiment 1, the first connector 1 and the second connector 2 are equipped with a reinforcement component 4 for secondary fixation of the first connector 1 and the second connector 2. The reinforcement component 4 includes a first fixing plate 401, which is fixedly connected to the outside of the second mounting cylinder 304. A spring rod 402 is elastically connected to the side of the first fixing plate 401. A second fixing plate 403 is fixedly connected to the outside of the first mounting cylinder 301. A through groove 405 is provided on the second fixing plate 403. A support plate 407 is fixedly connected to the top of the first mounting cylinder 301. A miniature electric telescopic rod 406 is fixedly connected through the inside of the support plate 407. A compression plate 404 is slidably connected to the outside of the first mounting cylinder 301. Two sets of spring rods 402 and two sets of through grooves 405 are provided.

[0029] In practical use, when the second mounting cylinder 304 approaches the first mounting cylinder 301, the first fixing plate 401 drives the two sets of spring rods 402 to press against the second fixing plate 403. When the second mounting cylinder 304 rotates, the first fixing plate 401 drives the two sets of spring rods 402 to insert into the through groove 405. When disassembling, the switch of the micro electric telescopic rod 406 is activated, causing the telescopic end of the micro electric telescopic rod 406 to move the pressing plate 404, which allows the spring rods 402 to detach from the second fixing plate 403. This solves the problem that the first connecting piece 1 and the second connecting piece 2 may detach under accidental circumstances, thus requiring further reinforcement.

[0030] The above description is only a preferred embodiment of the present utility model, but the protection scope of the present utility model is not limited thereto. Any equivalent substitutions or changes made by those skilled in the art within the technical scope disclosed in the present utility model, based on the technical solution and the inventive concept of the present utility model, should be included within the protection scope of the present utility model.
