Description

Technical Field

[0001] This invention relates to the field of hanging fence production technology, specifically to an automatic angle steel feeding rack for hanging fence production. Background Technology

[0002] Hanging fences, also known as suspended fences, are a type of suspended fence formed by hanging them from fixed points on the exterior facade or ceiling of a building. Compared to traditional post fences, hanging fences are more flexible and convenient to install and dismantle.

[0003] Generally, hanging fences are suspended high on the exterior wall of a building and require support from angle steel components with right-angled triangular structures. One right-angled side is attached to the exterior wall of the building, while the other right-angled side supports the work platform of the hanging fence. In order to facilitate disassembly and assembly, the angle steel is usually pre-produced and stored, and then transported to the site for direct assembly. Therefore, a material rack is needed to store the angle steel, and multiple angle steels are bundled together and fixed on the material rack for easy storage and transportation.

[0004] The shortcomings of existing angle steel feeding racks are as follows: After the angle steel used in existing hanging fences is manufactured, in order to prevent the workpieces from tipping over and swaying during transportation, multiple workpieces need to be manually tied and secured when placed on the feeding rack. The feeding rack cannot automatically limit and fix the placed workpieces, making the operation cumbersome and inconvenient, increasing the workload, and the manual binding and fixing is inefficient. In addition, when manually binding and fixing, multiple workpieces are usually fixed together at the same time, which can easily cause the workpieces to be squeezed during transportation, thus causing deformation and affecting subsequent use. Furthermore, when retrieving them later, since the workpieces are tied together, they need to be manually untied. And because multiple workpieces are fixed together, once untied, multiple workpieces will be scattered at the same time, making it impossible to select and use them as needed. Summary of the Invention

[0005] The purpose of this invention is to provide an automatic angle steel feeding rack for the production of hanging fences, so as to solve the technical problem that the existing angle steel feeding racks cannot automatically limit and fix the placed workpieces, and are not convenient to operate.

[0006] The technical problem to be solved by this invention can be achieved through the following technical solution:

[0007] An automatic angle steel feeding rack for hanging fence production includes a U-shaped support frame, on which a protective cover mechanism is provided, and further includes:

[0008] A scissor-type clamping mechanism is provided, wherein multiple sets of scissor-type clamping mechanisms are provided, and each set of scissor-type clamping mechanisms includes a first clamping rod and a second clamping rod. The first clamping rod and the corresponding second clamping rod are arranged crosswise. A first connecting crossbar is fixedly provided inside the U-shaped support frame, and the position where the first clamping rod and the corresponding second clamping rod intersect each other is rotatably connected to the first connecting crossbar. A clamping drive mechanism is provided on the rear side of the U-shaped support frame, and the clamping drive mechanism includes multiple horizontally distributed linkage sleeves.

Each set of flipping and pressing mechanisms is connected to the corresponding linkage sleeve.

[0010] As a further embodiment of the present invention: the clamping drive mechanism includes an electric telescopic rod, a linkage crossbar, and a magnetically detachable connector. Two sets of electric telescopic rods are provided and distributed on both sides of the U-shaped support frame. All power switches are electrically connected to the electric telescopic rods. The linkage crossbar is horizontally fixedly connected between the telescopic ends of the two electric telescopic rods.

[0011] As a further aspect of the present invention: each set of magnetically detachable connectors includes an electromagnet, a plug, and an iron block. The plug extends longitudinally through the linkage crossbar and is aligned with the linkage sleeve. The top of the linkage sleeve has a slot that mates with the corresponding plug. The iron block is fixedly connected to the top of the plug. A second connecting crossbar is fixedly arranged parallel to the top of the linkage crossbar. The electromagnet is fixedly connected to the second connecting crossbar and is aligned with the iron block. Each linkage sleeve is connected to the first connecting crossbar by an elastic sliding connector.

[0012] As a further embodiment of the present invention: the elastic sliding connector includes a connecting guide rail, the connecting guide rail is fixedly connected below the first connecting crossbar, and the connecting guide rail is aligned with the linkage sleeve. The bottom of the linkage sleeve is slidably connected to the connecting guide rail, and a limit spring is also provided between the bottom of the linkage sleeve and the connecting guide rail.

[0013] As a further embodiment of the present invention: each set of the flipping and pressing mechanism includes a traction mechanism, a guide sleeve, a lifting guide rod, a shaft frame, and a rotating pressure plate. The guide sleeve is fixedly connected below the first connecting crossbar. The lifting guide rod extends longitudinally through the guide sleeve. The top of the lifting guide rod is connected to the corresponding linkage sleeve through the traction mechanism. A hook rod is fixedly provided at the bottom of the lifting guide rod. The shaft frame is fixedly provided on one side of the corresponding V-shaped positioning groove. A connecting shaft is horizontally rotatably connected to the shaft frame, and a coil spring is connected between the connecting shaft and the shaft frame. One end of the connecting shaft is fixedly connected to the rotating pressure plate, and the other end is fixedly connected to a tilting plate. The hook rod is located at the bottom of the tilting plate. A thickened extrusion member is provided on the extrusion surface of the rotating pressure plate.

[0014] As a further embodiment of the present invention: the traction mechanism includes a traction steel wire and a fixed pulley. One end of the traction steel wire is fixedly connected to the linkage sleeve, and the other end is fixedly connected to the top of the corresponding lifting guide rod. The fixed pulley is rotatably disposed on the bottom side of the first connecting crossbar, and the fixed pulley cooperates with the traction steel wire.

[0015] As a further aspect of the present invention: the thickened extrusion part is a rubber sheet, and is fixedly connected to the extrusion surface of the rotating pressure plate by bolts.

[0016] As a further aspect of the present invention: the thickened extrusion component is an airbag, and an air pump connected to the airbag is fixedly installed inside the U-shaped support frame.

[0017] As a further embodiment of the present invention: the protective cover mechanism includes a top cover and a drive motor. The top cover is fitted onto the top of the U-shaped support frame, and one side of the top cover is rotatably connected to the U-shaped support frame. The drive motor is fixedly connected to the outer wall of one side of the U-shaped support frame, and the main shaft of the drive motor is coaxially connected to the rotating end of the top cover. A start button switch electrically connected to the drive motor is fixedly connected to the rear side of the U-shaped support frame. A compression spring is installed on the linkage crossbar, and the start button switch is laterally aligned with the compression spring.

[0018] As a further aspect of the present invention: the front and rear sides of the top cover are both connected with rubber curtains that cooperate with the U-shaped support frame.

[0019] The beneficial effects of this invention are:

[0020] 1. This invention uses a U-shaped support frame to support the angle steel components used for placing the hanging fence. Each angle steel component is positioned by a V-shaped positioning groove on one right-angled side and a scissor-type clamping mechanism on the other right-angled side. Once the U-shaped support frame is full of angle steel components, the power switch in each V-shaped positioning groove activates the circuit of the electric telescopic rod, causing all the linkage sleeves to move synchronously. Each linkage sleeve triggers the corresponding scissor-type clamping mechanism to clamp the components, achieving automatic clamping and fixing when the angle steel is full. This eliminates the need for manual bundling and packaging of the angle steel components, making operation convenient. Furthermore, the angle steel components are separated from each other, preventing deformation due to crowding.

[0021] 2. When the electric telescopic rod of the present invention drives all the linkage sleeves to move laterally, each linkage sleeve can be driven by the set traction steel wire to raise the corresponding lifting guide rod. The lifting guide rod then drives the rotating pressure plate distributed on one side of the V-shaped positioning groove to rotate in linkage with the hook rod, the inclined rocker plate and the connecting shaft. This allows the rotating pressure plate to limit the right angle side of the angle steel piece placed in the V-shaped positioning groove. The rotating pressure plate cooperates with the scissor-type clamping mechanism to effectively limit the entire angle steel piece in multiple directions, further ensuring the stability of the placed angle steel and facilitating transportation and use.

[0022] 3. When it is necessary to release all the angle steel limits, the present invention directly controls the electric telescopic rod to retract, driving all the linkage sleeves to reset, which allows the scissor-type clamping mechanism to open. At the same time, the rotating pressure plate rotates back to reset, making it easy to remove the angle steel. When it is necessary to remove a portion of the angle steel, the electromagnet at the corresponding position can be directly energized to generate magnetic force. In this way, the corresponding electromagnet attracts the set iron block, which drives the corresponding plug to rise. Since each linkage sleeve is fixed to the linkage crossbar by the plug, the limit is released after the corresponding linkage sleeve separates from the plug, and the elastic sliding connector rebounds to reset, thereby unlocking. The angle steel can be partially or completely unlocked and removed as needed.

[0023] 4. When the electric telescopic rod of the present invention extends and drives the linkage sleeve to move, it also acts on the set start button switch. The start button switch causes the drive motor to run, and the drive motor drives the opened top cover to flip over and cover the U-shaped support frame, realizing automatic sealing and facilitating protection during transportation.

[0035] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0036] like Figures 1-9As shown, an automatic angle steel feeding rack for the production of suspended fences is used to support the supporting angle steel parts 27 used for placing the suspended fences. Since the supporting angle steel parts 27 need to support and suspend the suspended fence on the outer wall of the building, such as when installing the suspended fence at a high position during the construction of a bridge pier, the supporting angle steel parts 27 need to be fixed to the outer wall of the bridge pier and support the main body of the suspended fence. Therefore, the supporting angle steel parts 27 are right-angled triangular structures, with one right-angled side attached to and fixed to the outer wall of the bridge pier, and the other right-angled side supporting the worktable of the suspended fence. After the supporting angle steel parts 27 are manufactured in the factory, they need to be placed and stored, so a feeding rack is required. The feeding rack specifically includes a U-shaped support frame 1. The bottom of the U-shaped support frame 1 is distributed with universal wheels with braking function, and a battery is also installed at the bottom. The U-shaped support frame 1 is equipped with a protective cover mechanism. After the supporting angle steel parts 27 are stacked inside the U-shaped support frame 1, the U-shaped support frame 1 is covered by the protective cover mechanism to facilitate protection during transportation.The feeding rack also includes a scissor-type clamping mechanism, a V-shaped positioning groove 5, and a flipping and pressing mechanism. Multiple sets of scissor-type clamping mechanisms are provided, laterally distributed in the upper space inside the U-shaped support frame 1. Each set of scissor-type clamping mechanisms includes a first clamping rod 15 and a second clamping rod 16. The first clamping rod 15 and the corresponding second clamping rod 16 are arranged crosswise, and a connecting pin 18 is rotatably provided at the intersection of the first clamping rod 15 and the corresponding second clamping rod 16. The first clamping rod 15 and the second clamping rod 16 can rotate around the connecting pin 18 respectively. A first connecting crossbar 8 is horizontally fixed in the upper space inside the support frame 1. The first clamping rod 15 and the second clamping rod 16 are rotatably connected to the first connecting crossbar 8 at their intersections via a connecting pivot pin 18. The connecting pivot pin 18 is fixed relative to the first connecting crossbar 8, facilitating the support of the first clamping rod 15 and the second clamping rod 16. A clamping drive mechanism is provided on the rear side of the U-shaped support frame 1, and the clamping drive mechanism includes multiple horizontally distributed linkage sleeves 13. One end of the first clamping rod 15 and the second clamping rod 16 cooperates to pass through the corresponding linkage sleeves. The moving sleeve 13, the other ends of the first clamping rod 15 and the second clamping rod 16 are clamping ends, and the first clamping rod 15 and the second clamping rod 16 can be respectively provided with a disc spring between them and the connecting pivot pin 18. The clamping ends of the first clamping rod 15 and the second clamping rod 16 are initially in an open state. The inner diameter of the moving sleeve 13 is smaller than the maximum width of the opening between the first clamping rod 15 and the second clamping rod 16. When the supporting angle steel piece 27 is placed in the U-shaped support frame 1, one right-angled side of the supporting angle steel piece 27 is horizontally supported at the bottom of the U-shaped support frame 1, and the other right-angled side is horizontally supported at the bottom of the U-shaped support frame 1. The corner edge rests between the clamping ends of the first clamping rod 15 and the second clamping rod 16 of one of the scissor-type clamping mechanisms. When the supporting angle steel 27 is mounted on all the scissor-type clamping mechanisms, the clamping drive mechanism is activated. The clamping drive mechanism drives all the linkage sleeves 13 to move laterally. During the lateral movement of the linkage sleeves 13, they squeeze and close the end through which the first clamping rod 15 and the second clamping rod 16 pass, so that the other ends of the first clamping rod 15 and the second clamping rod 16 move synchronously to achieve clamping, thereby clamping one right-angled edge of the supporting angle steel 27.

[0037] Multiple V-shaped positioning grooves 5 are provided and are laterally distributed on the inner bottom surface of the U-shaped support frame 1. The V-shaped positioning grooves 5 are used to hold the other right-angled side of the supporting angle steel piece 27, as shown in the figure below. Figure 6As shown, each V-shaped positioning groove 5 contains an energized switch 10, and all energized switches 10 are connected in series in the starting circuit of the clamping drive mechanism. That is, the clamping drive mechanism will only start when all energized switches 10 are closed. Thus, when all V-shaped positioning grooves 5 hold the supporting angle steel pieces 27, the clamping drive mechanism will automatically start. It should be noted that the energized switches 10 are elastic push-button switches to facilitate circuit closure under the pressure of the supporting angle steel pieces 27; pressing closes the circuit, releasing breaks it. Furthermore, for ease of pressure application, the energized switches 10 can be located at the bottom of the V-shaped positioning grooves 5. Each V-shaped positioning groove 5 corresponds to a scissor-type clamping mechanism, and multiple sets of flipping and pressing mechanisms are provided, arranged in pairs. On both sides of the V-shaped positioning groove 5, each set of flipping and pressing mechanisms is connected to the corresponding linkage sleeve 13. When the linkage sleeve 13 causes the corresponding scissor-type clamping mechanism to clamp one right-angle side of the supporting angle steel member 27, the corresponding flipping and pressing mechanism rotates and presses down on the supporting angle steel member 27 during the movement of the linkage sleeve 13, locking it into the other right-angle side in the corresponding V-shaped positioning groove 5. The flipping and pressing mechanism is also located inside the corner position of the two right-angle sides of the supporting angle steel member 27. In this way, the supporting angle steel member 27 cannot slide forward. At the same time, because it is clamped between the first clamping rod 15 and the second clamping rod 16, it cannot tilt backward. It is also restricted longitudinally by the flipping and pressing mechanism and cannot detach upward. At the same time, there is no mutual squeezing between adjacent supporting angle steel members 27, thus achieving protection.

[0038] In some specific implementation plans, combined with Figure 3 and Figure 5 As shown, the clamping drive mechanism includes an electric telescopic rod 14, a linkage crossbar 7, and a magnetic detachable connector. Two sets of electric telescopic rods 14 are provided and distributed on both sides of the U-shaped support frame 1, and are embedded inside the side plate. The telescopic ends of the electric telescopic rods 14 are horizontally rearward. All the power switches 10 are connected in series with the starting circuit of the electric telescopic rods 14. The linkage crossbar 7 is horizontally fixedly connected between the telescopic ends of the two electric telescopic rods 14. Multiple sets of magnetic detachable connectors are provided, and each linkage sleeve 13 is connected to the linkage crossbar 7 through the corresponding magnetic detachable connector.

[0039] Each set of magnetically detachable connectors includes an electromagnet 6, a plug 12, and an iron block 11. The plug 12 runs longitudinally through the linkage crossbar 7 and is aligned with the linkage sleeve 13. The top of the linkage sleeve 13 has a slot that matches the corresponding plug 12. The iron block 11 is fixedly connected to the top of the plug 12. The width of the iron block 11 is greater than the diameter of the plug 12. A second connecting crossbar 31 is fixedly installed parallel above the linkage crossbar 7. The electromagnet 6 is fixedly connected to the second connecting crossbar 31 and is aligned with the iron block 11. Each electromagnet 6 is equipped with a switch, that is, each electromagnet 6 is electrically connected to the battery pack through the corresponding switch. The switches can be distributed at the corresponding positions of the U-shaped support frame 1 as needed. Each linkage sleeve 13 is connected to the first connecting crossbar 8 by an elastic sliding connector.

[0040] Once the supporting angle steel pieces 27 are placed between each V-shaped positioning groove 5 and the corresponding scissor-type clamping mechanism, all the power switches 10 will be activated, causing the electric telescopic rod 14 to extend and move the linkage crossbar 7 backward. This, in turn, causes all the linkage sleeves 13 to move backward. Each linkage sleeve 13 causes the corresponding scissor-type clamping mechanism to clamp one right-angled side of the supporting angle steel piece 27, while the corresponding flipping and pressing mechanism presses down on the other right-angled side of the supporting angle steel piece 27. During this process, the linkage sleeves 13 cause the elastic sliding connector to generate a rebound force. When the required number of supports needs to be removed... When the supporting angle steel member 27 is supported, the corresponding number of electromagnets 6 are energized to generate magnetic force. Each energized electromagnet 6 attracts the corresponding iron block 11 to rise. The iron block 11 then drives the connected plug 12 to rise, and the plug 12 disengages from the linkage sleeve 13. This unlocks the connection between the linkage sleeve 13 and the linkage crossbar 7. Then, the linkage sleeve 13 resets under the rebound force of the corresponding elastic sliding connector, making it easy for the clamping ends of the corresponding first clamping rod 15 and second clamping rod 16 to be released. At the same time, the corresponding flipping and pressing mechanism also resets and disengages from the supporting angle steel member 27. This makes it easy to remove the supporting angle steel member 27 without having to unlock the limits at different positions separately.

[0041] In some specific implementation plans, such as Figure 6As shown, the elastic sliding connector includes a connecting guide rail 17, which is fixedly connected below the first connecting crossbar 8. The connecting guide rail 17 is aligned with the linkage sleeve 13 and is positioned in a front-to-back direction. The bottom of the linkage sleeve 13 is slidably connected to the connecting guide rail 17 via a slider. A compressible limiting spring 28 is also provided between the bottom of the linkage sleeve 13 and the connecting guide rail 17. Specifically, one end of the limiting spring 28 is fixedly connected to one end of the connecting guide rail 17, and the other end is fixedly connected to the slider at the bottom of the linkage sleeve 13. The slider is fixedly set relative to the linkage sleeve 13. When the linkage crossbar 7 drives the linkage sleeve 13 to slide, causing the first clamping rod 15 and the second clamping rod 16 to clamp the supporting angle steel piece 27, the linkage sleeve 13 slides along the connecting guide rail 17 and compresses the limiting spring 28. Thus, the limiting spring 28 generates a rebound force, which facilitates the sliding back and reset when the linkage sleeve 13 separates from the linkage crossbar 7.

[0042] In some specific implementation plans, combined with Figure 3 , Figure 4 , Figure 7 and Figure 8 As shown, each set of flipping and pressing mechanisms includes a traction mechanism, a guide sleeve 21, a lifting guide rod 22, a shaft frame 24, and a rotating pressure plate 9. The guide sleeve 21 is fixedly connected to the lower part of the first connecting crossbar 8 via a rod body. The lifting guide rod 22 extends longitudinally through the guide sleeve 21 and can slide up and down relative to the guide sleeve 21. The top of the lifting guide rod 22 is connected to the corresponding linkage sleeve 13 via the traction mechanism. A hook rod 30 is fixedly installed at the bottom of the lifting guide rod 22. The shaft frame 24 is fixedly installed on one side of the corresponding V-shaped positioning groove 5. A connecting shaft 25 is horizontally rotatably connected to the shaft frame 24, and a coil spring is connected between the connecting shaft 25 and the shaft frame 24. One end of the connecting shaft 25 is fixedly connected to the rotating pressure plate 9, and the other end is fixedly connected to the inclined rocker plate 29. The hook rod 30 is located at the bottom of the inclined rocker plate 29. It should be noted that the initial position of the rotating pressure plate 9 is in a vertical position, which has no effect on the placement of the supporting angle steel 27. A thickened extrusion part 23 is provided on the extrusion surface of the rotating pressure plate 9.

[0043] Among them, such as Figure 9 As shown, the traction mechanism includes a traction steel wire 20 and a fixed pulley 19. One end of the traction steel wire 20 is fixedly connected to the linkage sleeve 13, and the other end is fixedly connected to the top of the corresponding lifting guide rod 22. It should be noted that the lifting guide rod 22 is also configured with a horizontally bent end to facilitate connection with the traction steel wire 20. The fixed pulley 19 is rotatably set on the bottom side of the first connecting crossbar 8. The fixed pulley 19 rotates at a fixed point and cooperates with the traction steel wire 20.

[0044] When the linkage sleeve 13 moves laterally, it pulls the traction steel wire 20. The traction steel wire 20 then pulls the lifting guide rod 22 upward by the steering action of the fixed pulley 19. The lifting guide rod 22 slides upward along the guide sleeve 21 and rises. The lifting guide rod 22 then drives the hook rod 30 at the bottom to rise synchronously. Since the hook rod 30 is located at the bottom of the inclined plane 29, the hook rod 30 squeezes and pushes the inclined plane 29 to rotate. The inclined plane 29 then drives the rotating pressure plate 9 to rotate downward through the connecting shaft 25, so that the rotating pressure plate 9 can press against the supporting angle steel piece 27.

[0045] In some specific implementations, the thickened extrusion part 23 is a rubber sheet, which is fixedly connected to the extrusion surface of the rotating pressure plate 9 by bolts. The rubber sheet has different thicknesses, and the corresponding thickness of the rubber sheet can be replaced for use according to actual needs.

[0046] In some other specific implementations, the thickened extrusion member 23 is an airbag. An air pump connected to the airbag via a hose is fixedly installed inside the U-shaped support frame 1. When the rotating pressure plate 9 rotates, it cannot effectively contact the supporting angle steel member 27. The air pump inflates the airbag, making it expand, so that the extrusion action can be applied to the supporting angle steel member 27.

[0047] In some specific implementations, the protective cover mechanism includes a top cover 2 and a drive motor 3. The top cover 2 is fitted onto the top of the U-shaped support frame 1, and one side of the top cover 2 is rotatably connected to the U-shaped support frame 1 via a pivot. The drive motor 3 is fixedly connected to the outer wall of one side of the U-shaped support frame 1, and the main shaft of the drive motor 3 is coaxially connected to the rotating end of the top cover 2. A start button switch 26, which is electrically connected to the counterclockwise rotation control circuit of the drive motor 3, is fixedly connected to the rear side of the U-shaped support frame 1 via a mounting bracket. A compression spring 32 is installed on the linkage crossbar 7, and the start button switch 26 is laterally aligned with the compression spring 32. The drive motor 3 is also equipped with a control switch for controlling clockwise rotation. When it is necessary to place the support angle steel piece 27, the control switch controls the drive motor 3 to drive the top cover 2 to rotate clockwise and open, thereby facilitating the placement of the support angle steel piece 27. When the electric telescopic rod 14 drives the linkage sleeve 13 to move laterally through the linkage crossbar 7, so that the scissor-type clamping mechanism clamps, the compression spring 32 on the linkage crossbar 7 is activated. The spring 32 compresses the start button switch 26, causing the drive motor 3 to start and the top cover 2 to flip over and cover the U-shaped support frame 1 for protection. It should be noted that there are elastic switches distributed on the top of the two side plates of the U-shaped support frame 1. The elastic switches include a fixed conductor and a movable conductor. The movable conductor is connected to the fixed conductor by a spring, and the movable conductor and the fixed conductor are normally in contact and in a closed state. The movable conductor is lower than the fixed conductor and the two are laterally offset, with only their ends in contact, which facilitates energization. When the elastic switch is pressed, the movable conductor is compressed and detaches from the fixed conductor, thus breaking the circuit. When there is no external force, it is closed. This elastic switch is connected in series in the circuit connecting the start button switch 26 and the counterclockwise rotation control circuit of the drive motor 3. Once the top cover 2 flips over and covers the top of the U-shaped support frame 1, it is pressed against the elastic switch, causing the counterclockwise rotation control circuit to be disconnected, preventing the drive motor 3 from continuing to run and causing damage.

[0048] In some specific implementations, rubber curtains 4 are connected to both the front and rear sides of the top cover 2. The two rubber curtains 4 cover the front and rear openings of the U-shaped support frame 1, further enhancing protection. They are also easy to bend and lift up to check the internal situation.

[0049] To facilitate understanding of the embodiments of this solution by those skilled in the art, the working principle of this solution will now be briefly explained in conjunction with specific application scenarios:

[0050] After the support angle steel 27 is manufactured, one right-angled side of the support angle steel 27 is horizontally placed in the V-shaped positioning groove 5 at the bottom of the U-shaped support frame 1, and the other right-angled side rests between the first clamping rod 15 and the second clamping rod 16 of the corresponding scissor-type clamping mechanism. Then, multiple support angle steel 27s are placed in sequence.

[0051] After the supporting angle steel pieces 27 are placed between each V-shaped positioning groove 5 and the corresponding scissor-type clamping mechanism, all the power switches 10 will be activated. Since all the power switches 10 are connected in series with the starting circuit of the electric telescopic rod 14, the starting circuit of the electric telescopic rod 14 will be energized only when all the power switches 10 are pressed and closed. The electric telescopic rod 14 will then extend, thereby driving the linkage crossbar 7 to move backward. In this way, the linkage crossbar 7 will drive all the linkage sleeves 13 to move backward. During the lateral movement of each linkage sleeve 13, it will squeeze and close the end through which the corresponding first clamping rod 15 and second clamping rod 16 pass, so that the other ends of the first clamping rod 15 and second clamping rod 16 move synchronously to achieve clamping, thereby clamping the right-angle side of the supporting angle steel piece 27.

[0052] Furthermore, during the lateral movement of the linkage sleeve 13, it pulls the traction steel wire 20. The traction steel wire 20, relying on the steering action of the fixed pulley 19, pulls the lifting guide rod 22 upward. The lifting guide rod 22 then slides upward along the guide sleeve 21 and rises. The lifting guide rod 22 then drives the hook rod 30 at the bottom to rise synchronously. Since the hook rod 30 is located at the bottom of the inclined rocker plate 29, the hook rod 30 squeezes and pushes the inclined rocker plate 29 to rotate. The inclined rocker plate 29 then drives the rotating pressure plate 9 to rotate downward through the connecting shaft 25, thereby facilitating the rotating pressure plate 9 to press against the right-angled side of the supporting angle steel piece 27 located in the V-shaped positioning groove 5.

[0053] Furthermore, the rotating pressure plate 9 is located inside the corner of the two right-angled sides of the supporting angle steel member 27. As a result, the supporting angle steel member 27 cannot slide forward. At the same time, because it is clamped between the first clamping rod 15 and the second clamping rod 16, it cannot tilt backward. It is also restricted longitudinally by the rotating pressure plate 9 and cannot move upward to detach. Meanwhile, the adjacent supporting angle steel members 27 will not squeeze each other, thus achieving protection.

[0054] Furthermore, when the electric telescopic rod 14 drives the linkage sleeve 13 to move laterally through the linkage crossbar 7, so that the scissor-type clamping mechanism clamps, the compression spring 32 on the linkage crossbar 7 will press against the start button switch 26, causing the drive motor 3 to start and drive the top cover 2 to flip over and cover the U-shaped support frame 1 for protection, which is convenient for transportation.

[0055] When the corresponding number of supporting angle steel pieces 27 need to be removed, the corresponding number of electromagnets 6 are energized to generate magnetic force. Each energized electromagnet 6 attracts the corresponding iron block 11 to rise. The iron block 11 then drives the connected plug 12 to rise, and the plug 12 disengages from the linkage sleeve 13, thus unlocking the connection between the linkage sleeve 13 and the linkage crossbar 7. Then, the linkage sleeve 13 is reset under the rebound force of the corresponding elastic sliding connector, which facilitates the release of the clamping ends of the corresponding first clamping rod 15 and second clamping rod 16. At the same time, the corresponding rotating pressure plate 9 is also reset and disengaged from the supporting angle steel pieces 27 under the rebound force of the coil spring connected to the connecting shaft 25. This makes it convenient to remove the supporting angle steel pieces 27 without having to unlock the limits at different positions separately.

[0056] The foregoing has described several embodiments of the present invention in detail, but these embodiments are not limited thereto and should not be considered as limiting the scope of the invention. All equivalent variations and improvements made within the scope of the claims of this invention should still fall within the patent coverage of this invention.
