Description

Technical Field

[0001] This invention relates to the field of steel component docking construction technology, and in particular to a steel structure docking device for steel structure construction. Background Technology

[0002] Steel components mainly refer to combined structural members formed by welding or mechanical connection of steel plates, angle steel, channel steel, and other profiles. They belong to the field of industrial products, are mainly used to bear and transmit loads, and are characterized by light weight, high degree of industrialization, and quick construction.

[0003] The core materials for steel components include hot-rolled H-beams and cold-formed steel, and are suitable for construction projects such as high-rise buildings, large-span factories, bridges, and rail transit.

[0004] During the construction of steel components, to extend the length of the steel components, the docking of multiple steel structures is mainly achieved by personnel relying on their work experience and using tools. The tools used for docking are primarily positioning devices. However, during the docking process, these are easily affected by positional deviations, the weight of the steel components themselves, and the different types of steel components to be docked. Using a single docking clamp for overall operation is complex, time-consuming, and labor-intensive. Furthermore, a steel structure docking device for steel structure construction (publication number CN119244021A) utilizes the principle that when a rope is pulled under tension, it drives a movable hook to move, which in turn moves the corresponding clamping rod and clamping plate to clamp and fix steel structures of different shapes. It also uses the intermeshing of a worm gear and helical teeth to allow the rotating drive rod to change the angle of the fixed ring, thereby adjusting the angle of the steel structure to achieve precise docking. However, this method also suffers from the aforementioned problems. Therefore, how to provide a steel structure docking device for steel structure construction is a problem that urgently needs to be solved by those skilled in the art. Summary of the Invention

[0005] One objective of this invention is to provide a steel structure docking device for steel structure construction, in order to solve the problems that existing auxiliary tools for docking steel components are easily affected by positional deviation, the large weight of the steel components themselves, and the different types of steel components to be docked, and that the overall operation of using a single docking clamp is relatively complicated, time-consuming and labor-intensive.

[0006] According to an embodiment of the present invention, a steel structure docking device for steel structure construction includes a docking device base. A fixed docking bracket is provided on the top of one end of the docking device base, and a movable docking bracket is provided on the top of the end of the docking device base away from the fixed docking bracket. Positioning components are assembled and connected to the top of both the fixed docking bracket and the movable docking bracket.

The two ends of the connecting arc plate are respectively assembled and fixed to two inner lining rings. A first hydraulic push rod is hinged between the side surface of the connecting arc plate away from the inner lining ring and the outer side of the positioning support ring.

[0009] Preferably, the component mounting assembly includes a mounting tube, and a support plate is integrally formed at the bottom of the end of the mounting tube away from the positioning assembly. The bottom of the support plate has a second movable groove, and a support frame is provided on the outside of the support plate. A limiting slide is slidably connected to the inside of the support frame, and a pin is pinned to the inside of the limiting slide. The support frame is U-shaped, and one end is assembled and fixed to a fixed docking bracket or a movable docking bracket. A first movable groove is provided inside the support frame, and the support plate is slidably connected inside the first movable groove. The support plate is slidably connected to the inside of the limiting slide, and the pin passes through the inside of the second movable groove to limit the range of movement of the support plate from bottom to top.

[0010] Preferably, the interior of the erecting long pipe is provided with a positioning slot, which is composed of a right-angled triangular prism slot at the bottom and a semi-cylindrical slot at the top, and the right-angled triangular prism slot and the semi-cylindrical slot at the top are connected; the surface of the H-beam is in contact with the inner wall of the right-angled triangular prism slot, and the inner wall of the right-angled triangular prism slot is tangent to the outer surface of the circular steel component.

[0011] Preferably, guide strips are integrally formed on both long sides of the bottom of the movable docking bracket, and universal wheels are assembled and connected to the bottom of both ends of the guide strips. Two positioning grooves parallel to the long sides are opened inside the docking device base, and two guide slots are opened at the end of the docking device base away from the fixed docking bracket. The two guide slots are respectively connected to the ends of the two positioning grooves away from the fixed docking bracket. The two guide strips are slidably connected inside the two positioning grooves, and the two universal wheels at the bottom of the guide strips are rotatably connected inside the same positioning groove.

[0012] Preferably, the second hydraulic push rod is internally assembled with a first connector at the end near the fixed docking bracket, and internally assembled with a second connector at the end near the movable docking bracket; the bottom of the movable docking bracket is provided with a second storage slot on the side near the fixed docking bracket, and the bottom of the second hydraulic push rod at the end away from the fixed docking bracket extends into the interior of the second storage slot.

[0013] Preferably, the second connector includes a connecting corner block, one end of which is integrally formed with a fan-shaped disk; the first connector includes a connecting strip block, one end of which is integrally formed with a disc; the docking device base has a second limiting groove at the top near the fixed docking bracket, and the movable docking bracket has a first limiting groove at the bottom; the fan-shaped disk is movably connected inside the first limiting groove, and the disc is rotatably connected inside the second limiting groove.

[0014] Preferably, the top of the docking device base has two operating slots, both of which are connected to the interior of the first storage slot, and the two operating slots are located at the end of the first storage slot near the fixed docking bracket.

[0016] The beneficial effects of this invention are: 0. This invention passes a circular steel component through the interior of a long support pipe. A first hydraulic push rod controls the inner lining ring to rotate relative to the positioning support ring. Pressure is applied to the circular rod through a guide slot, causing the circular rod to drive an L-shaped slide block to move towards the center of the inner lining ring within the guide frame. This allows the positioning slider, assembled to the L-shaped slide block towards the center of the inner lining ring, to clamp the circular steel component. Additionally, an H-shaped steel component passes through the interior of the long support pipe, supported by the inner wall of the pipe. A limiting slide is controlled to drive a support plate to slide within the first movable groove, allowing the end of the long support pipe away from the support plate to extend into the inner lining ring, thus clamping and fixing the long support pipe. This invention can meet the docking requirements of two circular steel components of different diameters, as well as steel components with a similar H-shaped shape. It solves the problems of steel component docking auxiliary tools being easily affected by positional offsets, the large weight of the steel components themselves, and the different types of steel components to be docked, while using a single docking fixture is complex, time-consuming, and labor-intensive. 1. When adjusting the threaded connection between the threaded rod and the fixed docking bracket, the threaded rod tends to extend or retract from the inside of the fixed docking bracket towards the bottom. This helps to correct the deviation when the two positioning components are aligned, ensuring that the two positioning components are in an aligned state, thereby meeting the docking requirements of the steel components. 2. This invention utilizes the universal wheels at the bottom of the guide strip to guide one end of the guide strip into the interior of the positioning strip groove through the guide slot. Then, by rotating the second hydraulic push rod inside the first receiving slot, the first connecting member rotates inside the docking device base, causing the second connecting member at the end of the second hydraulic push rod away from the first connecting member to rotate. This causes the fan-shaped disc on the second connecting member to cut into the first limiting slot at the bottom of the movable docking bracket, which helps to restrict the movable docking bracket from moving back, forth, left, and right on the top of the docking device base without external force.

Detailed Implementation

[0020] The present invention will now be described in further detail with reference to the accompanying drawings. These drawings are simplified schematic diagrams, illustrating only the basic structure of the invention, and therefore only show the components relevant to the invention.

[0021] Example 1: The technical solution in this application embodiment addresses the problem that the aforementioned steel component docking auxiliary tools are easily affected by positional offsets, the large weight of the steel components themselves, and the different types of steel components to be docked, while using a single docking fixture results in complex overall operation that is time-consuming and labor-intensive. The general approach is as follows: To address the problems existing in the prior art, the present invention provides a schematic diagram of a steel structure docking device for steel structure construction, with reference to... Figures 1 to 6 , Figure 10 The device includes a docking device base 4, a fixed docking bracket 7 is provided on the top of one end of the docking device base 4, a movable docking bracket 2 is provided on the top of the end of the docking device base 4 away from the fixed docking bracket 7, a positioning component 1 is assembled and connected to the top of both the fixed docking bracket 7 and the movable docking bracket 2, a component mounting component 9 is provided on the opposite side of the movable docking bracket 2 and the fixed docking bracket 7, and a first storage slot 3 is opened on the top of the end of the docking device base 4 away from the fixed docking bracket 7, and a second hydraulic push rod 6 is provided inside the first storage slot 3. Both positioning components 1 include a positioning support ring 102. The inner rings 101 are rotatably connected to the inside of both sides of the positioning support ring 102. Three guide frames 103 are integrally formed on the opposite side surface of the two inner rings 101. L-shaped slide blocks 105 are slidably connected inside the three guide frames 103. A positioning slider 104 is assembled and connected to the end of the L-shaped slide block 105 near the center of the inner ring 101. A round rod 106 is integrally formed at the end of the L-shaped slide block 105 away from the positioning slider 104. Three guide slots 11 with equal spacing and surrounding the center are opened inside both sides of the positioning support ring 102. The positioning support ring 102 has an I-shaped cross section. Three guide frames 103 are arranged at equal intervals around the center of the inner lining ring 101. The round rod 106 and the positioning slider 104 are located on both sides of the guide frame 103. The three round rods 106 are slidably connected to the inside of the three guide slots 11. When the steel component is assisted by the component erection assembly 9 and passed through the inner side of the inner lining ring 101, the inner lining ring 101 is controlled to rotate relative to the positioning support ring 102. The guide slots 11 apply pressure to the round rod 106, causing the round rod 106 to drive the L-shaped slide 105 to move toward the center of the inner lining ring 101. The round tube steel component can be clamped inside the positioning support ring 102 by using six positioning sliders 104 in groups of three. This helps to ensure that the steel component clamped and fixed by the two positioning assemblies 1 is in a coaxial state. At the same time, the second hydraulic push rod 6 controls the movable docking bracket 2 to move closer to the side of the fixed docking bracket 7, so that the steel components dock between the two positioning components 1, thereby supporting the docking parts to fix the two steel components together. Secondly, to facilitate control of the rotation of the inner liner ring 101 relative to the positioning support ring 102 inside it, such as... Figure 3 and Figure 5 As shown, the positioning support ring 102 has three arc-shaped slots 12 inside. Each of the three arc-shaped slots 12 has a connecting arc plate 108 on its inner side. The two ends of the connecting arc plate 108 are respectively assembled and fixed to the two inner lining rings 101. The side surface of the connecting arc plate 108 away from the inner lining ring 101 is hinged to the outer side of the positioning support ring 102 with a first hydraulic push rod 107. By assembling and fixing the two ends of the connecting arc plate 108 to the two inner lining rings 101 respectively, the two inner lining rings 101 can be assembled and fixed on the inner side of the positioning support ring 102, ensuring that the two inner lining rings 101 are in a synchronous moving state. Meanwhile, when the first hydraulic push rod 107 is between the inner liner ring 101 and the positioning support ring 102, and controls the inner liner ring 101 to rotate relative to the positioning support ring 102, the guide groove 11 machined inside the positioning support ring 102 can be used to cooperate with the round rod 106 on the L-shaped slide block 105 to control the sliding state of the L-shaped slide block 105 inside the guide frame 103 without manual control. The component erection assembly 9 includes an erection tube 901. The bottom of the erection tube 901 away from the positioning assembly 1 is integrally formed with a support plate 902. The bottom of the support plate 902 is provided with a second movable groove 14. The support plate 902 is provided with a support frame 903 on the outside. The inner side of the support frame 903 is slidably connected to a limiting slide 904. The inner side of the limiting slide 904 is pin-connected to a pin block 905. The interior of the long pipe 901 is provided with a positioning slot, which is composed of a right-angled triangular prism slot at the bottom and a semi-cylindrical slot at the top. The right-angled triangular prism slot and the semi-cylindrical slot at the top are connected. The support frame 903 is U-shaped, with one end fixed to the fixed docking bracket 7 or the movable docking bracket 2. The support frame 903 has a first movable groove 13 inside, and the support plate 902 is slidably connected inside the first movable groove 13. By slidably connecting the support plate 902 to the inside of the limiting slide 904, the pin block 905 passes through the inside of the second movable groove 14, restricting the range of movement of the support plate 902 from bottom to top. When the circular steel component 15 passes through the interior of the supporting long pipe 901... The inner wall of the right-angled triangular prism groove is tangent to the outer surface of the circular steel component 15. When the inner lining ring 101 rotates relative to the positioning support ring 102, the guide slot 11 applies pressure to the round rod 106, causing the round rod 106 to drive the L-shaped slide 105 to move toward the center of the inner lining ring 101. When the positioning slider 104, which is assembled to the L-shaped slide 105 toward the center of the inner lining ring 101, clamps the circular steel component 15, the circular steel component 15 moves upward inside the supporting long tube 901 and remains coaxial with the inner lining ring 101. Meanwhile, when the H-beam 16 is passed through the interior of the erecting tube 901, the surface of the H-beam 16 is in contact with the inner wall of the right-angled triangular prism groove. The control limiting slide 904 drives the support plate 902 to slide inside the first movable slot 13, so that the end of the erecting tube 901 away from the support plate 902 extends into the inner side of the inner lining ring 101. When the inner lining ring 101 rotates relative to the positioning support ring 102, the guide slot 11 applies pressure to the round rod 106, so that the round rod 106 drives the L-shaped slide 105 to move toward the center of the inner lining ring 101. At this time, the erecting tube 901 can be clamped and fixed, and the support plate 902 slides to the top outside the pin block 905 through the second movable slot 14. At this time, since the erecting tubes 901 on the two component erecting assemblies 9 are in a coaxial state, the H-beam 16 inside the erecting tube 901 can be kept in an aligned state. In some examples, the four corners of the bottom of the fixed docking bracket 7 are movably connected to the limit rods 8, and the fixed docking bracket 7 is internally threaded with threaded rods 17. In this process, by threading the bottom of the limiting rod 8 into the interior of the docking device base 4, and using the bottom of the threaded rod 17 to support the top surface of the docking device base 4, when adjusting the threaded connection between the threaded rod 17 and the fixed docking bracket 7, the threaded rod 17 tends to extend or retract from the interior of the fixed docking bracket 7 to the bottom, so that the fixed docking bracket 7 can be positioned up and down outside the four limiting rods 8, which is beneficial for adjusting the deviation according to the actual alignment of the two positioning components 1. In this embodiment, by passing the circular steel component 15 through the interior of the erected long pipe 901, the first hydraulic push rod 107 controls the inner lining ring 101 to rotate relative to the positioning support ring 102 on the inner side. The guide slot 11 applies pressure to the circular rod 106, causing the circular rod 106 to drive the L-shaped slide block 105 to move towards the center of the inner lining ring 101 inside the guide frame 103. This causes the positioning slider 104, which is assembled to the L-shaped slide block 105 towards the center of the inner lining ring 101, to clamp the circular steel component 15. In this state, the circular steel components 15 on the inner side of the inner lining ring 101 at the two positioning components 1 are in a coaxial state. When the second hydraulic push rod 6 controls the movable docking bracket 2 to move closer to the fixed docking bracket 7, the two circular steel components 15 can be docked and fixed by means of docking devices, without being limited by whether the diameters of the two circular steel components 15 are the same. Meanwhile, by passing the H-beam 16 through the interior of the erecting long tube 901 and supporting it with the inner wall of the erecting long tube 901, the limiting slide 904 drives the supporting plate 902 to slide inside the first movable groove 13, allowing one end of the erecting long tube 901 away from the supporting plate 902 to extend into the inner side of the inner lining ring 101. When the inner lining ring 101 rotates relative to the positioning support ring 102, and the guide slot 11 applies pressure to the round rod 106, causing the round rod 106 to drive the L-shaped slide 105 to move toward the center of the inner lining ring 101, the erecting long tube 901 can be clamped and fixed, and the supporting plate 902 can slide to the top outside the pin block 905 through the second movable groove 14, so that the erecting long tubes 901 on the two component erecting assemblies 9 are in a coaxial state. For the H-beam 16 inside the erecting long tube 901, it can be kept in an aligned state, which is convenient for steel components with similar H-beam 16 shapes to be connected. In addition, in order to ensure that the two positioning components 1 can be aligned, when adjusting the threaded connection between the threaded rod 17 and the fixed docking bracket 7, the threaded rod 17 tends to extend or retract from the inside of the fixed docking bracket 7 towards the bottom, which helps to correct the deviation when the two positioning components 1 are aligned.

[0022] Example 2: Based on Example 1, this application's embodiment describes the basic structure configuration state when the movable docking bracket 2 and the fixed docking bracket 7 are close to each other. The overall concept is as follows: like Figure 1 , Figure 2 , Figures 6 to 10 As shown, guide strips 20 are integrally formed on the two long sides of the bottom of the movable docking bracket 2. Universal wheels 19 are assembled and connected to the bottom of both ends of the guide strips 20. Two positioning grooves 5 parallel to the long sides are opened inside the docking device base 4. Two guide slots 11 are opened at the end of the docking device base 4 away from the fixed docking bracket 7. A second storage slot 21 is opened at the bottom of the movable docking bracket 2 on the side close to the fixed docking bracket 7. The second hydraulic push rod 6 is internally assembled with a first connecting piece 18 near the fixed docking bracket 7. The second hydraulic push rod 6 is internally assembled with a second connecting piece 22 near the movable docking bracket 2. The second connecting piece 22 includes a connecting corner block 222, and one end of the connecting corner block 222 is integrally formed with a fan-shaped disk 221. The first connecting piece 18 includes a connecting strip 182, and one end of the connecting strip 182 is integrally formed with a disc 181. The docking device base 4 is provided with a second limiting groove 24 at the top near the fixed docking bracket 7, and the movable docking bracket 2 is provided with a first limiting groove 23 at the bottom. In this configuration, the two guide slots 11 are connected to the ends of the two positioning slots 5 away from the fixed docking bracket 7, and the two guide bars 20 are slidably connected inside the two positioning slots 5. When the movable docking bracket 2 moves in the horizontal plane, the two universal wheels 19 at the bottom of the guide bar 20 are slidably connected inside the same positioning slot 5. Based on the guidance of the guide slots 11 to the guide bars 20, the guide bars 20 can be quickly slid into the interior of the positioning slots 5, so that the movable docking bracket 2 is positioned by the docking device base 4 and its movement in the horizontal plane is restricted. Secondly, by extending the bottom of the second hydraulic push rod 6 away from the fixed docking bracket 7 into the interior of the second receiving slot 21, while keeping the disc 181 rotatably connected inside the second limiting slot 24, the second hydraulic push rod 6 can be controlled to rotate inside the first receiving slot 3, so that the fan-shaped disc 221 is movably connected inside the first limiting slot 23, completing the connection work between the second connector 22 and the bottom of the movable docking bracket 2, thereby allowing the second hydraulic push rod 6 to control the movable docking bracket 2 to move on the top of the docking device base 4, guided by the guide bar 20 and the positioning groove 5; Furthermore, to facilitate control of the rotation of the second hydraulic push rod 6 inside the first receiving slot 3, such as... Figure 9 As shown, the top of the docking device base 4 has two operating slots 10. Both operating slots 10 are connected to the inside of the first storage slot 3. The two operating slots 10 are located at the end of the first storage slot 3 near the fixed docking bracket 7. When the second hydraulic push rod 6 is rotated inside the first storage slot 3, the first connecting member 18 rotates inside the docking device base 4, and drives the second connecting member 22 at the end of the second hydraulic push rod 6 away from the first connecting member 18 to rotate. This causes the fan-shaped disk 221 on the second connecting member 22 to cut into the first limiting slot 23 at the bottom of the movable docking bracket 2, restricting the movable docking bracket 2 from moving at the top of the docking device base 4 without external force.

[0023] In this embodiment, by placing the second hydraulic push rod 6 inside the first receiving slot 3, and placing the first connecting piece 18 at one end of the second hydraulic push rod 6 inside the second limiting slot 24 and keeping it movable, when the movable docking bracket 2 is controlled to move on the ground, the universal wheel 19 at the bottom of the guide strip 20 guides one end of the guide strip 20 into the positioning slot 5 through the guide slot 11. Then, by rotating the second hydraulic push rod 6 inside the first receiving slot 3, the first connecting piece 18 rotates inside the docking device base 4, driving the second connecting piece 22 at the end of the second hydraulic push rod 6 away from the first connecting piece 18 to rotate, so that the fan-shaped disk 221 on the second connecting piece 22 cuts into the first limiting slot 23 at the bottom of the movable docking bracket 2, which helps to restrict the movable docking bracket 2 from moving back, forth, left, and right on the top of the docking device base 4 without external force.

[0024] Specifically, when using this device to perform operations: First, the second hydraulic push rod 6 is installed inside the first receiving slot 3, so that the first connecting piece 18 at one end of the second hydraulic push rod 6 is placed inside the second limiting slot 24 and remains in a movable state. Subsequently, with the help of four casters 19, the guide bar 20 at the bottom of the movable docking bracket 2 is guided by the guide slot 11 and slid into the interior of the positioning slot 5, and cooperates with it to restrict the movable docking bracket 2 from moving back and forth on the top of the docking device base 4. At the same time, the second hydraulic push rod 6 is rotated inside the first storage slot 3, causing the first connector 18 to rotate inside the docking device base 4, which in turn drives the second connector 22 at the end of the second hydraulic push rod 6 away from the first connector 18 to rotate, causing the fan-shaped disk 221 on the second connector 22 to cut into the first limiting slot 23 at the bottom of the movable docking bracket 2, thus restricting the movable docking bracket 2 from moving left and right at the top of the second hydraulic push rod 6. Next, based on the docking work of the circular steel component 15: The circular steel component 15 is passed through the interior of the erected long pipe 901. The inner lining ring 101 is rotated relative to the positioning support ring 102 by the first hydraulic push rod 107. The circular rod 106 is pressed by the guide slot 11, so that the circular rod 106 drives the L-shaped slide block 105 to move towards the center of the inner lining ring 101 inside the guide frame 103. This causes the positioning slider 104, which is assembled to the L-shaped slide block 105 towards the center of the inner lining ring 101, to clamp the circular steel component 15. In this state, the circular steel members 15 inside the inner lining ring 101 of the two positioning components 1 are in a coaxial state. When the second hydraulic push rod 6 controls the movable docking bracket 2 to move closer to the fixed docking bracket 7, the two circular steel members 15 can be docked and fixed with the help of the docking device (the connector of the existing steel member). The docking work between the two circular steel members 15 can be carried out quickly without being restricted by whether the diameters of the two circular steel members 15 are the same. Based on the connection work of steel components with a shape similar to H-beam 16: The control limit slider 904 drives the support plate 902 to slide inside the first movable groove 13, so that the end of the support tube 901 away from the support plate 902 extends into the inner side of the inner lining ring 101, and the H-beam 16 passes through the inside of the support tube 901 and is supported by the inner wall of the support tube 901. When the inner lining ring 101 rotates relative to the positioning support ring 102, the guide slot 11 applies pressure to the round rod 106, so that the round rod 106 drives the L-shaped slide 105 to move toward the center of the inner lining ring 101. This can clamp and fix the support tube 901, and make the support plate 902 slide to the top outside the pin block 905 through the second movable groove 14. In this state, based on the coaxial state of the erection tubes 901 on the two component erection assemblies 9, the H-beams 16 inside the erection tubes 901 can be kept aligned (the specifications of the two H-beams 16 are the same), and the docking work of steel components with similar shapes to H-beams 16 can be carried out.
