Description

Technical Field

[0001] This invention belongs to the field of clamp structures, specifically relating to a clamp connection device for fixing steel structures. Background Technology

[0002] In steel structure construction, the traditional connection method is mainly welding. Although welding is strong, it has problems such as high on-site construction difficulty, high technical requirements for operators, long construction period, and non-removable connection, as well as subsequent maintenance, which seriously affect the structural strength and construction efficiency.

[0003] Therefore, existing technologies use clamp structures to connect and install steel structures. However, these traditional clamp structures usually have the problem of not being universally applicable to steel sections of different diameters. Furthermore, during the bolt connection process of the clamp, due to long-term use, factors such as vibration, stress concentration, and corrosion may affect the bolt connection of the clamp, which may lead to breakage or loosening, resulting in connection failure and causing safety accidents or equipment malfunctions.

[0004] This application proposes a clamp connection device for fixing steel structures, which improves upon the aforementioned defects. Summary of the Invention

[0005] The technical problem to be solved by the present invention is to overcome the shortcomings of the prior art and provide a clamp connection device for fixing steel structures that can be installed on steel structures of different diameters and has an anti-fall-off function.

[0006] To solve the above-mentioned technical problems, the present invention adopts the following technical solution:

[0007] A clamp connection device for fixing steel structures includes a clamp structure and connecting units. Several connecting units are rotatably fitted on the outer wall of the clamp structure. The other end of each connecting unit can be connected to another set of clamp structures, thereby assembling several clamp structures.

[0008] In one specific implementation scheme, the clamp structure includes an upper buckle assembly, a lower buckle assembly, a steering seat, bolts, and an anti-detachment device. The lower buckle assembly is located at the bottom of the upper buckle assembly. The upper buckle assembly and the lower buckle assembly have the same structure and are fixed by bolts. The bolts are detachable. Steering seats are installed on the outer surfaces of both the upper buckle assembly and the lower buckle assembly. The steering seats are rotatably engaged with the connecting unit. An anti-detachment device is installed between the upper buckle assembly and the lower buckle assembly. The anti-detachment device is located between the two sets of bolts.

[0009] In one specific implementation scheme, the upper buckle assembly includes a rubber cover, an inner expansion plate, a connecting plate, an outer expansion plate, a side plate, and a connecting seat. Several inner expansion plates are connected to the outer side of the rubber cover. Both sides of the several inner expansion plates are rotatably engaged with connecting plates via rotating shafts. The other end of the several connecting plates is rotatably engaged with several outer expansion plates and side plates. The steering seat is fixed on the outer expansion plate. The two sets of side plates are located on the left and right outermost sides of the upper buckle assembly, with one side fixed to the rubber cover and the other side fixed to the connecting seat. The bolts and anti-detachment devices are both installed on the connecting seat.

[0010] In one specific implementation scheme, the connecting unit includes a first universal ball, a first rotating seat, a ball socket, a ball head, a second rotating seat, a second universal ball, and an outer cover. One end of the first universal ball is connected to the first rotating seat, and the other end of the first rotating seat is fixed with a ball socket. A ball head is rotatably fitted on the ball socket. The ball head is mounted on the second rotating seat. A second universal ball is mounted on the end of the second rotating seat away from the ball head. An outer cover is mounted on the first rotating seat and the second rotating seat.

[0011] In one specific feasible implementation, the first universal ball is embedded inside the steering seat on the clamp structure and rotates in cooperation with it, while the second universal ball rotates in cooperation with the steering seat on another set of clamp structures, enabling the two sets of clamp structures to be modularly assembled.

[0012] In one specific implementation, the anti-detachment device is installed between the upper buckle assembly and the lower buckle assembly.

[0013] In one specific implementation scheme, the anti-fall-off device includes a column, a fixing ring, an inner top device, and a sliding ring. The column is fixed on the upper buckle assembly, and the fixing ring is fixed on the column. The inner top device is rotatably fitted on the outer wall of the fixing ring through a bearing seat. The other end of the inner top device is rotatably fitted with the sliding ring. The sliding ring is installed on the column, and the column is installed between the upper buckle assembly and the lower buckle assembly.

[0014] In one specific implementation, the column is provided with a sliding groove and a locking groove.

[0015] In one specific implementation, the inner top device includes a first rotating rod, a second rotating rod, and a top rod, with the other end of the first rotating rod rotatably engaged with the second rotating rod, and a top rod fixed on the inner side of the second rotating rod.

[0016] In one specific implementation, an alarm unit is installed on the side wall of the connector on the upper buckle assembly, and the alarm unit is electrically connected to an external central control unit and a central control room.

[0017] In one specific implementation, the sliding ring includes protrusions, sliding rods, and limiting blocks. The inner wall of the sliding ring has an array of protrusions, which are spherical and movably engaged with the slots on the column. The top of the sliding ring is fixed with a plurality of sliding rods, which are slidably engaged with the sliding grooves. The top of the sliding rods is fixed with limiting blocks.

[0018] In one specific implementation, the length of the slide groove is greater than the length of the slide rod. When the sliding ring is installed on the column through the protrusion, the sliding ring is located below the lower buckle assembly, and the limiting block is located above the column, which is the initial position.

[0019] According to the above-mentioned technical solution, the clamp connection device for fixing steel structures of the present invention has the following beneficial effects:

[0020] (1) By modular design of clamp structure and connection unit, this invention can flexibly combine several clamp structures into various connection forms such as "T", "L", "cross", parallel docking, etc., which is highly versatile and can improve the installation efficiency of steel structure. Moreover, the multi-modal connection can combine steel structures in different connection directions into one, increasing the installation stability of steel structure.

[0021] (2) The present invention embeds the first and second universal balls on the connecting unit into the clamp structure and rotates with them. By rotating the two sets of rotating seats and universal balls, and the ball head located between the rotating seats, the connecting unit can be rotated in three stages, thereby adjusting the assembly angle of the two sets of clamp structures assembled with each other.

[0022] (3) By setting the clamp structure as an adjustable structure, the present invention can adjust the diameter of the upper buckle assembly and the lower buckle assembly by pulling outward several expansion plates, and by using several connecting plates connected to the expansion plates to move outward synchronously with the expansion plates, thereby driving several inner expansion plates connected to the other end and the rubber cover connected to the inner expansion plates to move outward synchronously and expand, thus making it suitable for the installation and fixing of steel structures of different diameters.

[0023] (4) The present invention provides an anti-loosening device on the clamp structure. When the bolt is loose, the sliding ring moves downward synchronously under the gravity of the steel structure, which will drive the sliding rod to move in the groove until the limiting block contacts the column and stops. The position of the lower buckle component is limited by the limiting block, which can prevent the lower buckle component from moving downward and increase the safety performance of the clamp structure.

Detailed Implementation

[0036] To make the technical means, creative features, objectives and effects of this invention easier to understand, the invention will be further described below in conjunction with specific embodiments.

[0037] Example 1: Please refer to Figures 1-5The specific embodiments of the present invention are as follows:

[0038] A clamp connection device for fixing steel structures includes a clamp structure 1 and a connecting unit 2. Several connecting units 2 are rotatably fitted on the outer wall of the clamp structure 1. The other end of each connecting unit 2 can be connected to another set of clamp structures 1, thereby assembling several clamp structures 1 to form a modular design for flexible assembly. The clamp structure 1 can be used to fix and install the steel structure.

[0039] Please see Figure 1-2 The clamp structure 1 includes an upper buckle assembly 11, a lower buckle assembly 12, a steering seat 13, bolts 14, and an anti-detachment device 15. The lower buckle assembly 12 is provided at the bottom of the upper buckle assembly 11. The upper buckle assembly 11 and the lower buckle assembly 12 have the same structure and are fixed by bolts 14. They can fit together to form a ring structure. The bolts 14 are detachable. Steering seats 13 are installed on the outer surfaces of both the upper buckle assembly 11 and the lower buckle assembly 12. The steering seats 13 are rotatably engaged with the connecting unit 2. An anti-detachment device 15 is installed between the upper buckle assembly 11 and the lower buckle assembly 12. The anti-detachment device 15 is located between the two sets of bolts 14.

[0040] Please see Figure 3 The upper buckle assembly 11 includes a rubber cover 111, an inner expansion plate 112, a connecting plate 113, an outer expansion plate 114, a side plate 115, and a connecting seat 116. Several inner expansion plates 112 are connected to the outer side of the rubber cover 111. Both sides of the several inner expansion plates 112 are rotatably engaged with the connecting plate 113 through a rotating shaft. The other end of the several connecting plates 113 is rotatably engaged with the several outer expansion plates 114 and the side plate 115. The steering seat 13 is fixed on the outer expansion plate 114. The two sets of side plates 115 are located on the left and right outermost sides of the upper buckle assembly 11, with one side fixed to the rubber cover 111 and the other side fixed to the connecting seat 116. Bolts 14 and anti-detachment devices 15 are both installed on the connecting seat 116.

[0041] Please see Figures 3-4 When it is necessary to fix steel structures of different diameters, by pulling outward several expansion plates 114, several connecting plates 113 connected to the expansion plates 114 can move outward synchronously with the expansion plates 114, thereby driving several inner expansion plates 112 connected to the other end and the rubber cover 111 connected to the inner expansion plates 112 to move outward synchronously and expand, thereby adjusting the diameter of the upper buckle assembly 11 and the lower buckle assembly 12, which is suitable for fixing steel structures of different diameters.

[0042] Please see Figures 3-4By utilizing the elasticity and stretchability of the rubber structure of the rubber cover 111, it can stretch and expand as the inner expansion plate 112 moves when the diameter of the upper buckle assembly 11 and the lower buckle assembly 12 is adjusted. Furthermore, when the rubber material is in contact with and fixed to the steel structure, it can avoid damage to the steel structure and increase the effect of buffering and shock absorption.

[0043] Please see Figure 5 The connecting unit 2 includes a first universal ball 21, a first rotating seat 22, a ball socket seat 23, a ball head 24, a second rotating seat 25, a second universal ball 26, and an outer cover 27. One end of the first universal ball 21 is connected to the first rotating seat 22, and the other end of the first rotating seat 22 is fixed with the ball socket seat 23. The ball head 24 is rotatably fitted on the ball socket seat 23. The ball head 24 is mounted on the second rotating seat 25, and the second universal ball 26 is mounted on the end of the second rotating seat 25 away from the ball head 24. The outer cover 27 is mounted on the first rotating seat 22 and the second rotating seat 25. The outer cover 27 can cover the ball socket seat 23 and the ball head 24 to prevent dust from entering.

[0044] Please see Figure 5 The first universal ball 21 is embedded in the steering seat 13 on the clamp structure 1 and rotates with it. The second universal ball 26 rotates with the steering seat 13 on another set of clamp structures 1. The two sets of clamp structures 1 can be modularly assembled. By rotating the two sets of rotating seats and universal balls, and the ball head located between the rotating seats, three-stage universal rotation can be performed, thereby adjusting the assembly angle of the two sets of clamp structures 1 assembled with each other. It can be flexibly combined into various connection forms such as "T-type", "L-type", "cross-type", and parallel docking.

[0045] Example 2: Please refer to Figures 6-10 The specific embodiments of the present invention are as follows:

[0046] Please see Figure 6 The anti-detachment device 15 is installed between the upper buckle assembly 11 and the lower buckle assembly 12, and can detect the closure degree of the clamp structure 1 in real time.

[0047] See Figures 6-7 The anti-fall-off device 15 includes a column 31, a fixing ring 32, an inner top device 33, and a sliding ring 34. The column 31 is fixed on the upper buckle assembly 11. The fixing ring 32 is fixed on the column 31. The inner top device 33 is rotatably fitted on the outer wall of the fixing ring 32 through a bearing seat. The other end of the inner top device 33 is rotatably fitted with the sliding ring 34. The sliding ring 34 is installed on the column 31. The column 31 is installed between the upper buckle assembly 11 and the lower buckle assembly 12.

[0048] Please see Figures 7-8 The column 31 is provided with a sliding groove 311 and a slot 312.

[0049] Please see Figures 7-8 The inner top device 33 includes a first rotating rod 331, a second rotating rod 332 and a top rod 333. The other end of the first rotating rod 331 is rotatably engaged with the second rotating rod 332, and the top rod 333 is fixed on the inner side of the second rotating rod 332.

[0050] Please see Figure 6 An alarm unit 151 is installed on the side wall of the connecting seat 116 on the upper buckle assembly 11. The alarm unit 151 can be electrically connected to the external central control unit and the central control room. When the top rod 333 on the inner top device 33 is pushed up, it will contact the alarm unit 151 and trigger the alarm unit 151 to operate, transmitting an electrical signal to the central control unit in the central control room to remind that the bolt 14 is loose.

[0051] Please see Figure 9 The sliding ring 34 includes a protrusion 341, a slide rod 342, and a limiting block 343. The inner wall of the sliding ring 34 has an array of protrusions 341, which are spherical and are movably engaged with the slots 312 on the column 31 to install the sliding ring 34 on the column 31. The top of the sliding ring 34 is fixed with a number of slide rods 342, which are slidably engaged with the slide grooves 311. The top of the slide rods 342 is fixed with a limiting block 343.

[0052] Please see Figures 7-9 The length of the groove 311 is greater than the length of the slide rod 342. When the sliding ring 34 is installed on the column 31 through the protrusion 341, the sliding ring 34 is located below the lower buckle assembly 12, and the limiting block 343 is located above the column 31, which is the initial position. When the bolt 14 loosens, the lower buckle assembly 12 will move downward under the action of the weight of the steel structure after losing the fixation of the bolt 14. This will squeeze the sliding ring 34 so that it is not fixed to the column 31, and cause it to move downward synchronously. As the sliding ring 34 moves downward, it will cause the slide rod 342 to move in the groove 311 until the limiting block 343 contacts the column 31 and stops. The limiting block 343 can limit the position of the lower buckle assembly 12 and prevent the lower buckle assembly 12 from moving downward.

[0053] Based on the above embodiments, the specific working principle is as follows:

[0054] During the installation of the steel structure, the upper fastening component 11 and the lower fastening component 12 on the clamp structure 1 are combined to install and fix the steel structure. The two sets of clamp structures 1 are connected and assembled by the connecting unit 2 located on the clamp structure 1. The first universal ball 21 is embedded in the steering seat 13 on one set of clamp structures 1, and the second universal ball 26 at the other end rotates and cooperates with the other set of clamp structures 1, so that the two sets of clamp structures 1 are modularly assembled. Through the two sets of rotating seats and universal balls on the connecting unit 2, and the ball head located between the rotating seats, the connecting unit 2 can be rotated in three stages to adjust the assembly angle of several sets of clamp structures 1 assembled with each other, and can be flexibly combined into various connection forms of steel structures, thereby improving the efficiency of steel structure assembly.

[0055] Furthermore, by pulling outward several expansion plates 114, several connecting plates 113 connected to the expansion plates 114 move outward synchronously with the expansion plates 114, thereby driving several inner expansion plates 112 connected to the other end and the rubber cover 111 connected to the inner expansion plates 112 to move outward synchronously and expand, thereby adjusting the diameter of the upper buckle assembly 11 and the lower buckle assembly 12, thus making it suitable for the installation and fixing of steel structures of different diameters;

[0056] When the bolt 14 on the clamp structure 1 becomes loose, the lower buckle assembly 12, having lost the fixation of the bolt 14, will move downward under the weight of the steel structure, pressing the sliding ring 34 below and causing it to detach from the column 31. As the sliding ring 34 moves downward, it will cause the sliding rod 342 to move within the sliding groove 311 until the limiting block 343 contacts the column 31 and stops. The limiting block 343 limits the position of the lower buckle assembly 12, preventing it from moving downward. As the sliding ring 34 moves downward, it will cause the second rotating rod 332 connected to it to rotate synchronously, thereby causing the top rod 333 on one side to push upward and contact the alarm unit 151, triggering the alarm unit 151 to operate and transmitting an electrical signal to the central control unit in the central control room, alerting that the bolt 14 is loose.

The power supply is also common knowledge in the art. Therefore, the present invention will not explain the control method and circuit connection in detail.
