Description

Technical Field

[0001] This invention relates to the field of steel structure construction technology, specifically to an on-site high-altitude splicing and disassembly operation platform for steel columns. Background Technology

[0002] In steel structure construction, factors such as component weight and transportation need to be considered. For steel columns with large individual component weight and long length, they need to be disassembled. During the installation process, the steel column interfaces are connected at high altitudes, and an operating platform that is easy for construction personnel to operate is set up at the interface.

[0003] In existing technologies, when assembling the operating platform, bolts or wire binding are commonly used. Such assembly methods cannot guarantee the strength of the steel frame assembly, posing safety hazards to construction workers. Furthermore, when using bolted connections, the bolts need to be removed one by one when disassembling the operating platform, and when using wire connections, the wire is usually cut directly, resulting in unnecessary waste of time and materials. Therefore, a steel column on-site high-altitude splicing and easy-to-disassemble operating platform is needed to solve the above problems. Summary of the Invention

[0004] The purpose of this invention is to provide an easy-to-assemble and disassemble operating platform for high-altitude on-site splicing of steel columns, so as to solve the problems mentioned in the background art.

[0005] To solve the above-mentioned technical problems, the present invention is achieved through the following technical solution:

[0006] This invention relates to a high-altitude, easily detachable operating platform for steel column assembly, comprising a frame, a support plate, a railing, and a tray. The support plate consists of eight sections, each with a square sleeve fixedly installed on both sides of its upper surface away from the frame center. The railing is positioned above the support plate, with a crossbar fixedly connected to one end of the railing near the support plate, and connecting legs fixedly connected to both sides of the railing near the support plate. The connecting legs are fitted inside the square sleeves. The tray is positioned below the support plate. The platform also includes: a connecting assembly comprising a shaped block and a knob; the shaped block is positioned at the connection point of every two adjacent support plates, with a threaded cylinder fixedly connected to its upper surface; the knob is positioned directly above the threaded cylinder; a fixing mechanism comprising a fixing component including a first connecting rod, a second connecting rod, and a third connecting rod; the fixing component is positioned at the center of the side of each support plate away from the frame center; and a clamping support mechanism comprising several arc-shaped plates evenly distributed around the tray below the support plate.

[0007] Furthermore, the bearing plate has the same irregular grooves at both ends on the side away from the center of the frame. The irregular grooves on two adjacent bearing plates share a common round hole. The square sleeve and the connecting leg share the same stepped slot. The square sleeves on the same bearing plate are connected together by a vertical plate. The vertical plate is symmetrically fixedly connected to two U-shaped grooves on the side away from the center of the frame. The opposite side walls of the U-shaped grooves are provided with sliding grooves.

[0008] Furthermore, two mounting plates are symmetrically fixedly connected to the lower surface of the support plate away from the center of the frame. A dovetail-shaped slider is fixedly connected between the side of the mounting plates that are close to each other and the lower surface of the support plate. Two sliding blocks are symmetrically arranged on the side of the mounting plates that are close to each other. A dovetail groove is opened on the upper surface of the sliding block. The sliding block is slidably mounted on the dovetail-shaped slider through the dovetail groove. A circular groove is opened on the side of the sliding block that is close to each other. An installation groove is opened on the side wall of the sliding block away from the center of the frame. A tension spring is fixedly connected between the mounting plate and the sliding block.

Circular shafts are symmetrically fixedly connected to both sides of the mounting column. A shock-absorbing plate is fixedly connected to the lower surface of the mounting column.

[0009] Furthermore, two sets of oppositely oriented locking teeth are symmetrically fixedly connected to the side wall of the crossbar away from the center of the frame. A limiting sleeve is slidably provided on the crossbar. Two identical upper and lower protrusions are fixedly connected to the side of the limiting sleeve away from the center of the frame. Several protrusions are fixedly connected to the inner wall of the limiting sleeve near the locking teeth. Sufficient gaps are left between the inner wall of the limiting sleeve away from the protrusions and the side wall of the crossbar. Eight pairs of uprights are evenly fixedly connected to the upper surface of the support plate. A lifting groove is fixedly connected to the end of the uprights away from the support plate.

[0010] Furthermore, the irregularly shaped block is fitted into two adjacent irregularly shaped grooves on two adjacent bearing plates. The threaded cylinder passes through the circular hole and extends to the top of the bearing plate. A compression spring is fixedly connected to the upper surface of the threaded cylinder. A threaded sleeve is fixedly connected to the end of the compression spring away from the threaded cylinder. A horizontal plate is fixedly connected to the side wall of the threaded sleeve. A guide groove is provided on the horizontal plate.

[0011] Furthermore, a bolt is fixedly connected to the lower surface of the knob, and the bolt is threaded into the inside of the threaded sleeve. A pair of rings are provided between the knob and the threaded sleeve, and the rings are fitted onto the bolts. Two connecting plates are fixedly connected to the side walls of the two rings. Both ends of the connecting plates are rotatably connected to the same pair of steering plates. The upper and lower steering plates on the same side are rotatably connected to the connecting plate, and the two steering plates are rotatably connected to the two ends of the connecting plate. A triangular plate is fixedly connected to the side of the connecting plate away from the bolt, and the triangular plate is fitted into the stepped groove.

[0012] Furthermore, the first, second, and third connecting rods are all provided with the same mounting holes, and insert rods are installed on the first, second, and third connecting rods through the mounting holes. Each of the first, second, and third connecting rods consists of two rotating rods, and the first, second, and third connecting rods are rotatably connected to the insert rods. The end of the first connecting rod away from the insert rod is rotatably connected to the inside of the protrusion plate. The end of the second connecting rod away from the insert rod is fixedly connected to a sliding column, which is slidably connected to the inside of the sliding groove. The end of the third connecting rod away from the insert rod is rotatably connected to the inside of the mounting groove.

[0013] Furthermore, a set of arc-shaped blocks are fixedly connected to the middle of the outer sidewall of the arc-shaped plate. A rotating plate is rotatably connected inside the arc-shaped blocks. A long groove is opened inside the rotating plate. Both sides of the rotating plate away from the arc-shaped blocks are fixedly connected to mating columns, which are fitted and installed inside the circular groove.

[0014] Furthermore, a sliding rod is slidably arranged inside the long groove, and a first rotating rod is fixedly connected to both ends of the sliding rod. A T-shaped groove is opened on the side of the first rotating rod that is close to each other, and a locking post is fixedly connected to the end of the first rotating rod that is away from the sliding rod and the side that is far away from each other. The first rotating rod is installed inside the lifting groove through the cooperation of the locking post.

[0015] Furthermore, a pair of second rotating rods are rotatably connected inside the first rotating rod, and a T-shaped slider is fixedly connected to the side of the second rotating rod that is far away from each other. The T-shaped slider is slidably disposed inside the T-shaped groove, and the end of the second rotating rod that is far away from the first rotating rod is rotatably connected to a round shaft.

[0016] The present invention has the following beneficial effects:

[0017] (1) By setting up a connecting mechanism, rotating the knob will cause the bolt to move towards the side closer to the threaded cylinder. At this time, the knob pushes the ring to move synchronously, thereby causing the steering plate to rotate and push the triangular plate into the cavity of the connecting leg and the square sleeve. Then the bolt and the threaded cylinder cooperate. At this time, the ring located below just contacts the threaded sleeve. The ring will push the threaded sleeve to move down synchronously, and then the triangular plate will enter the lower end of the stepped groove, limiting the triangular plate to prevent it from falling off. The triangular plate can also strengthen the connection between the two adjacent sets of bearing plates and the fence. At the same time, the bolt will pull the threaded cylinder and the irregular block and the irregular groove to fit tightly, vertically clamping the fence and the bearing plate to ensure the stability of the connection.

[0018] (2) By setting up a fixing mechanism, the present invention allows the insertion rod to cooperate with the first connecting rod, the second connecting rod and the third connecting rod, and controls and pulls the limiting sleeve closer to each other. At this time, the included angle between the first connecting rods decreases, and the second connecting rod and the third connecting rod move synchronously, thereby allowing the two sliding blocks to move closer to each other, thereby achieving clamping of the mating column, which facilitates the installation of the clamping support mechanism. The characteristic of the tension spring contraction will pull the sliding blocks away from each other, thereby increasing the included angle between the first connecting rod, the second connecting rod and the third connecting rod, causing the insertion rod to move towards the side closer to the center of the frame, pushing the limiting sleeve to move. The locking teeth and the convex teeth cooperate to limit the limiting sleeve, and at the same time have a pushing effect on the crossbar and even the fence, preventing the fence connection from being unstable and causing the fence to tilt and fall.

[0019] (3) By setting up a clamping support mechanism, the present invention controls the operation platform to fall, the lifting groove will push the clamping column and the first rotating rod to move, thereby driving the movement of the clamping support mechanism. The arc plate moves towards the side closer to the steel structure column to clamp the steel structure column, and at the same time, it can support the bearing plate in the opposite direction to increase its rigidity and reduce the safety hazards of workers during operation.

[0020] Of course, any product implementing this invention does not necessarily need to achieve all of the advantages described above at the same time. Attached Figure Description

Several protrusions 213 are fixedly connected to the inner wall of the limiting sleeve 211 near the locking teeth 2101. Sufficient gap is left between the inner wall of the limiting sleeve 211 away from the protrusions 213 and the side wall of the crossbar 21. Eight pairs of uprights 31 are evenly fixedly connected around the upper surface of the support plate 3. A lifting groove 32 is fixedly connected to the end of the upright 31 away from the support plate 3. The purpose of this arrangement is to facilitate the limiting sleeve 211 to be limited, prevent the first connecting rod 61 from rotating, and facilitate the support of the railing 2.

[0038] The irregular block 4 is installed in two adjacent irregular grooves 101 on two adjacent support plates 1. The threaded cylinder 41 passes through the round hole 102 and extends to the top of the support plate 1. A compression spring 42 is fixedly connected to the upper surface of the threaded cylinder 41. A threaded sleeve 43 is fixedly connected to the end of the compression spring 42 away from the threaded cylinder 41. A horizontal plate 431 is fixedly connected to the side wall of the threaded sleeve 43. A guide groove 432 is provided on the horizontal plate 431. The purpose of this arrangement is to facilitate the use of the control knob to control the movement of the triangular plate 541 and to tighten the irregular block 4.

[0039] A bolt 51 is fixedly connected to the lower surface of the knob 5. The bolt 51 is threaded into the inside of the threaded sleeve 43. A pair of rings 52 are provided between the knob 5 and the threaded sleeve 43. The rings 52 are fitted onto the bolt 51. Two connecting plates 521 are fixedly connected to the side walls of the two rings 52. Both ends of the connecting plates 521 are rotatably connected to a pair of identical turning plates 53. The purpose of this arrangement is to facilitate the use of the turning plates 53 to push the triangular plate 541 into the stepped slot 111. The two turning plates 53 on the same side are rotatably connected to a connecting plate 54. The two turning plates 53 are rotatably connected to the two ends of the connecting plate 54. A triangular plate 541 is fixedly connected to the side of the connecting plate 54 away from the bolt 51. The triangular plate 541 is fitted into the stepped slot 111. The purpose of this arrangement is to facilitate the use of the triangular plate 541 to enter the stepped slot 111 to fix the fence 2 and the square sleeve 11.

[0040] The first connecting rod 61, the second connecting rod 62, and the third connecting rod 63 all have the same mounting hole 64, and the first connecting rod 61, the second connecting rod 62, and the third connecting rod 63 are fitted with the insertion rod 65 through the mounting hole 64.

The end of the first connecting rod 61 away from the insertion rod 65 is rotatably connected to the inside of the protrusion plate 212. The end of the second connecting rod 62 away from the insertion rod 65 is fixedly connected to a sliding column 621, which is slidably connected inside the sliding groove 122. The purpose of this arrangement is to protect the insertion rod 65 and prevent it from deforming due to excessive load caused by the insertion rod 65 being too long. The end of the third connecting rod 63 away from the insertion rod 65 is rotatably connected inside the mounting groove 143. The purpose of this arrangement is to facilitate the control of the rotation of the third connecting rod 63 by using the connection of the insertion rod 65.

[0041] A set of arc-shaped blocks 701 are fixedly connected to the middle of the outer sidewall of the arc-shaped plate 7. The purpose of this arrangement is to facilitate the use of the arc of the arc-shaped plate 701 and the steel column to ensure the stability of the clamping. A rotating plate 71 is rotatably connected inside the arc-shaped block 701. The rotating plate 71 has a long groove 711 inside. Both sides of the rotating plate 71 away from the arc-shaped block 701 are fixedly connected to the mating column 712. The mating column 712 is installed in the circular groove 142. The purpose of this arrangement is to facilitate the installation of the first rotating rod 721 and to facilitate the disassembly of the rotating plate 71.

[0042] A slide rod 72 is slidably installed inside the long groove 711. Both ends of the slide rod 72 are fixedly connected to a first rotating rod 721. A T-shaped groove 722 is opened on the side of the first rotating rod 721 that is close to each other. A locking post 723 is fixedly connected to the end of the first rotating rod 721 that is away from the slide rod 72 and the side that is far away from each other. The first rotating rod 721 is installed inside the lifting groove 32 through the locking post 723. The purpose of this arrangement is to facilitate the movement of the first rotating rod 721 by squeezing the support plate 3 during installation.

[0043] A pair of second rotating rods 73 are rotatably connected inside the first rotating rod 721. A T-shaped slider 731 is fixedly connected to the side of the second rotating rods 73 that is away from each other. The T-shaped slider 731 is slidably disposed inside the T-shaped groove 722. The end of the second rotating rod 73 that is away from the first rotating rod 721 is rotatably connected to the round shaft 161. The purpose of this arrangement is to facilitate the rotation of the rotating plate 71 by the contraction and rotation of the first rotating rod 721 and the second rotating rod 73.

[0044] In use, the operating platform body needs to be assembled first. First, the eight sets of bearing plates 1 and the fence 2 are assembled by connecting legs 22 and square sleeves 11. Then, the irregular block 4 is installed inside the irregular groove 101, and the triangular block 541 is installed on the upper end of the stepped slot 111. Then, the knob 5 is rotated. Due to the setting of the knob 5 and the threaded sleeve 43, the bolt 51 will move towards the side closer to the threaded sleeve 41. At this time, the knob 5 pushes the ring 52 to move synchronously, which in turn causes the steering plate 53 to rotate, pushing the triangular plate 541 into the cavity of the connecting legs 22 and the square sleeve 11. Then, the bolt 51 continues to move downward until it engages with the threaded sleeve 41. At this point, the lower ring 52 just contacts the threaded sleeve 43. Then, the bolt 51 moves down, and the ring 52 pushes the threaded sleeve 43 to move down synchronously. Then, the triangular plate 541 enters the lower end of the stepped groove 111, which limits the triangular plate 541 to prevent it from falling off. The triangular plate 541 can also strengthen the connection between the two adjacent sets of bearing plates 1 and the fence 2. At the same time, the bolt 51 will pull the threaded sleeve 41 and the irregular block 4 to engage tightly with the irregular groove 101, vertically clamping the fence 2 and the bearing plate 1 to ensure the stability of their connection.

[0045] Then, the limiting sleeve 211 is separated, and the first connecting rod 61, the second connecting rod 62, and the third connecting rod 63 are engaged. The insert rod 65 is then inserted into the mounting hole 64. At this point, due to the action of the tension spring 15, the sliding blocks 14 are pulled apart, facilitating the engagement of the mating post 712 on the rotating plate 71 into the circular groove 142. Afterward, the limiting sleeve 211 can be controlled and pulled closer together. This reduces the angle between the first connecting rods 61, while the second connecting rod 62 and the third connecting rod 63 move synchronously, causing the two sliding blocks 14 to move closer together. This clamps the mating post 712, facilitating the clamping support mechanism. After installation, the limiting sleeve can be loosened. Due to the contraction of the tension spring 15, the sliding block 14 will be pulled away from each other, thereby increasing the angle between the first connecting rod 61, the second connecting rod 62 and the third connecting rod 63, causing the insertion rod 65 to move towards the center of the frame. Furthermore, through the setting of the limiting sleeve 211, the internal gap of the limiting sleeve 211 and the cooperation with the crossbar 21 can be manually controlled. When the tension spring 15 contracts and drives the fixing mechanism to move, the locking tooth 2101 and the protruding tooth 213 cooperate to limit the limiting sleeve 211, and at the same time have a pushing effect on the crossbar 21 and even the fence 2, preventing the fence 2 from being unstable and causing the fence 2 to tilt and fall.

[0046] Finally, when the clamping support mechanism is installed, the operating platform can be combined with the steel structure column. First, the support plate 3 is correctly placed on top of the steel structure column. Then, the operating platform is hoisted so that the clamping column 723 cooperates with the lifting groove 32. The operating platform is controlled to fall, and the lifting groove 32 will push the clamping column 723 and the first rotating rod 721 to move. At this time, the second rotating rod 73 retracts into the first rotating rod 721. At the same time, the first rotating rod 721 and the second rotating rod 73 rotate simultaneously. The sliding rod 72 slides inside the long groove 711, which can drive the rotating rod 71 to rotate. At this time, the arc plate 7 moves towards the side closer to the steel structure column to clamp the steel structure column. At the same time, it can support the bearing plate 1 in the opposite direction, increasing its rigidity and reducing the safety hazards for workers during operation.
