Description

Technical Field

[0001] The utility model relates to the technical field of connection structures, in particular to a connection structure of a crane steel structure component. Background Art

[0002] A crane is a mechanical device used to lift and move heavy objects. It is widely used in construction, manufacturing, logistics, ports, and other fields. The basic function of a crane is to move heavy objects from one location to another using a mechanical arm, ropes, or other means. The connections between the various components of a crane are generally assembled using a structure.

[0003] When assembling steel structures, bolts or pins are often used for connection. The existing method of fixing pins is generally to first insert the pin rod into the connection part of the steel structure and then insert the R-shaped pin into the pin hole in the pin rod for fixation. This split structure is prone to falling off due to the vibration force generated during use. During installation, the relatively small specifications of the R-shaped pin also increase the difficulty of workers in aligning and inserting it.

[0004] Therefore, it is necessary to provide a new crane steel structure component connection structure to solve the above technical problems. Utility Model Content

[0005] In order to solve the above technical problems, the utility model provides a crane steel structure component connection structure.

[0006] The crane steel structure component connection structure provided by the utility model comprises: a pin rod and a through rod, wherein the end of the pin rod is provided with a mounting groove, and the interior of the pin rod is provided with a mounting component for erecting the through rod;

[0007] The mounting assembly includes a support frame, which is arranged inside the pin rod. The support frame is provided with sliding plates that are symmetrically distributed and slidably connected. The opposite back surfaces of the two sliding plates are provided with fixedly connected through rods. The opposite ends of the two through rods extend to the outside of the pin rod, and a tension spring is provided between the sliding plates and the pin rod.

[0008] Preferably, a mounting groove is provided at the end of the pin rod, mounting compartments are provided on both sides of an inner wall of the mounting groove, and the inner wall of the mounting compartment is connected to the outer wall of the support frame.

[0009] Preferably, a through hole is provided in the interior of the installation groove at a position opposite to the through rod, and the inner wall of the through hole abuts against and is slidably connected to the outer wall of the through rod.

[0010] Preferably, a slope is provided on one end of the outer wall of the pin rod close to the mounting groove.

[0011] Preferably, a protruding rod and a gripping rod are provided on one side wall of the two sliding sheets away from the center of the pin rod, and the length of the gripping rod is greater than the length of the protruding rod.

[0012] Preferably, a fixedly connected fixing frame is set between the two installation bins, a fixedly connected threaded cylinder is provided inside the fixing frame, a threadedly connected limiting cylinder is sleeved inside the threaded cylinder, and the inner wall of the limiting cylinder is against the outer walls of the two protruding rods.

[0013] Preferably, one end of the tension spring is fixedly connected to the inner wall of the mounting groove, and the other end of the tension spring is fixedly connected to the outer wall of the sliding sheet.

[0014] Compared with the related art, the crane steel structure component connection structure provided by the utility model has the following beneficial effects:

[0015] 1. The utility model installs the through rod at the end of the pin rod through the installation component. Compared with the traditional fixing method of inserting an external R-shaped pin thread, this installation method has a more compact integrated structure and can reduce the phenomenon of the through rod used to prevent the pin rod from sliding and falling off from the pin rod, thereby improving the stability of the device when in use.

[0016] 2. The utility model movably inserts the through rod into the pin rod. Compared with the use of traditional R-type pins, when multiple disassembly and installation are performed in the later stage, the phenomenon of repeated swinging and breakage during repeated use can be reduced, thereby improving the cycle life of the device.

[0024] In order to make the purpose, technical solutions and advantages of the present invention more clearly understood, the present invention is further described in detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are only used to explain the present invention and are not intended to limit the present invention.

[0025] The specific implementation of the present invention is described in detail below with reference to specific embodiments.

[0026] See also Figures 1 to 5 The embodiment of the present invention provides a crane steel structure component connection structure, which includes: a pin rod 1 and a through rod 221. The end of the pin rod 1 is provided with a mounting groove 11, and the interior of the pin rod 1 is provided with a mounting component 2 for erecting the through rod 221.

[0027] In the embodiments of the present invention, please refer to Figures 1 to 5 The mounting assembly 2 includes a support frame 21, which is arranged in the pin rod 1. The support frame 21 is provided with sliding sheets 22 that are symmetrically distributed and slidably connected. The opposite back surfaces of the two sliding sheets 22 are provided with a fixedly connected through rod 221. The opposite ends of the two through rods 221 extend to the outside of the pin rod 1, and a tension spring 23 is provided between the sliding sheet 22 and the pin rod 1. A mounting groove 11 is provided at the end of the pin rod 1, and mounting bins 13 are provided on both sides of the inner wall of the mounting groove 11, and the inner wall of the mounting bin 13 is connected to the outer wall of the support frame 21. One end of the tension spring 23 is fixedly connected to the inner wall of the mounting groove 11, and the other end of the tension spring 23 is fixedly connected to the outer wall of the sliding sheet 22.

[0028] It should be noted that: the through rod 221 is installed on the end of the pin rod 1 through the installation component 2. Compared with the traditional fixing method of inserting an external R-shaped pin, this installation method has an excellent integrated structure. At the same time, compared with the transmission split structure, it can also reduce the phenomenon of the R-shaped pin loosening and falling. By movably inserting the through rod 221 into the pin rod 1, when multiple disassembly and installation are performed in the later stage, compared with the use of traditional R-shaped pins, the phenomenon of repeated swinging and breakage during repeated use can be reduced, thereby improving the cycle life of the device.

[0029] After the pin rod 1 is inserted and installed, the tension spring 23 can ensure that the through rod 221 always has the force to move outward, thereby reducing the phenomenon of the through rod 221 shrinking and falling off during use, thereby improving the stability of the device in later use.

[0030] In the embodiments of the present invention, please refer to Figures 1 to 5 A through hole 12 is provided inside the mounting groove 11 at a position opposite to the through rod 221 , and the inner wall of the through hole 12 abuts against and slides against the outer wall of the through rod 221 , and a slope 14 is provided on one end of the outer wall of the pin rod 1 close to the mounting groove 11 .

[0031] It should be noted that: by setting the through hole 12, the through rod 221 can be easily slid in the pin rod 1, thereby realizing the ejection or retraction movement of the through rod 221, and by providing a slope 14 on the outer wall of the pin rod 1, the slope 14 structure can reduce the specifications of the end of the pin rod 1, so that the end of the pin rod 1 can form a conical structure. Therefore, when installing the pin rod 1, when there is a certain misalignment in the docking of the required steel structure fork, the end of the pin rod 1 with a conical structure can also be stably inserted into the socket of the steel structure fork, and then the pin rod 1 can be completely penetrated and installed by hitting the pin rod 1, thereby improving the installation experience of the pin rod 1.

[0032] In the embodiments of the present invention, please refer to Figures 1 to 5 A protruding rod 24 and a gripping rod 25 are provided on one side wall of the two sliding pieces 22 away from the center of the pin rod 1, and the length of the gripping rod 25 is greater than the length of the protruding rod 24. A fixed frame 3 with the same fixed connection is set between the two mounting chambers 13, and a fixed threaded cylinder 31 is provided inside the fixing frame 3. A threaded limiting cylinder 32 is sleeved inside the threaded cylinder 31, and the inner wall of the limiting cylinder 32 is against the outer wall of the two protruding rods 24.

[0033] It should be noted that: through the setting of the limiting cylinder 32, when installing this device, the limiting cylinder 32 is screwed to the outside of the protruding rod 24 to abut against the outer wall of the protruding rod 24, thereby blocking the sliding piece 22, and then the through rod 221 on the sliding piece 22 can be retracted into the installation groove 11 in the pin rod 1, so that when the pin rod 1 is installed later, the through rod 221 can be prevented from obstructing the insertion path of the pin rod 1 during installation, making the insertion of the pin rod 1 smoother.

[0034] The working principle of the crane steel structure component connection structure provided by the utility model is as follows;

[0035] When using this connection structure, the staff can first connect the yokes that need to be connected in the crane steel structure assembly, then take out the pin rod 1 and insert it into the socket after the steel structure yoke is connected to achieve the penetration of the yoke;

[0036] Then, the staff can hold the gripping rods 25 at the ends of the two sliding pieces 22 to keep them moving relative to each other. During this process, the limiting cylinder 32 can be controlled to rotate inside the threaded cylinder 31 and move away from the through-rod 221 until the inner wall of the limiting cylinder 32 separates from the outer wall of the protruding rod 24. Then, the gripping force on the gripping rod 25 can be released.

[0037] At this time, the tension spring 23 on the outer wall of the sliding piece 22 will stretch the sliding piece 22 through its own force, so that the East China piece can drive the through rod 221 to move on the outer wall of the support frame 21 in a direction away from the center of the pin rod 1. At this time, the moving through rod 221 can pass through the through hole 12 from the inner wall of the pin rod 1 to the outside of the pin rod 1, thereby blocking the axial movement trajectory of the pin rod 1 after installation, thereby preventing the pin rod 1 from falling off from the yoke of the steel structure and achieving the connection of the steel structure;

[0038] When it is necessary to dismantle and separate the crane steel structure at a later time, the staff can first hold the gripping rod 25, so that it drives the through-rod 221 from the outer wall of the pin rod 1 to retract into the mounting groove 11 inside the pin rod 1 through the sliding piece 22, and at the same time control the limiting cylinder 32 to rotate in the opposite direction until the inner wall of the limiting cylinder 32 abuts against the outer wall of the protruding rod 24 at the end of the sliding piece 22, and the protruding rod 24 can complete the blocking of the sliding piece 22 away from the center of the pin rod 1. Then, the blocking of the through-rod 221 on the axial movement track of the pin rod 1 can be released, so that the pin rod 1 can be smoothly pulled out and disassembled from the yoke of the steel structure;

[0039] By adopting a movably installed method for storing the through rod 221 inside the pin rod 1, the phenomenon of the through rod 221 falling off and being lost during use can be reduced. At the same time, by movably inserting the through rod 221 into the pin rod 1, when it is disassembled and installed multiple times in the later stage, compared with the use of traditional R-type pins, the phenomenon of repeated swinging and breakage during repeated use can be reduced, thereby improving the cycle life of the device.

[0040] The above are merely embodiments of the present invention and are not intended to limit the patent scope of the present invention. Any equivalent structure or equivalent process transformation made using the contents of the present invention specification and drawings, or directly or indirectly applied in other related technical fields, are also included in the patent protection scope of the present invention.
