Description

Technical Field

[0001] This invention relates to the field of support frame technology, and more particularly to a movable support frame. Background Technology

[0002] The statements herein provide only background information in relation to this invention and do not necessarily constitute prior art.

[0003] Temporary support frames are indispensable key equipment in many engineering fields, such as the assembly of large-span steel trusses in building construction, the segmented construction of ships, and bridge construction.

[0004] However, the support frames used in the existing technology for installation on the inter-layer trusses are usually fixed and need to be completely dismantled after each layer of trusses is installed and reassembled on the next layer, which is cumbersome and increases construction time. Summary of the Invention

[0005] The purpose of this invention is to address the aforementioned shortcomings by providing a movable support frame.

[0006] To solve the above-mentioned technical problems, the present invention adopts the following technical solution: a movable support frame, comprising a frame body fixed to the inter-layer truss, and further comprising: A climbing formwork frame, located on the outer side of the truss, is used to support the vertical climbing of the main body of the formwork frame; The removal mechanism is movably mounted on the climbing formwork and connected to the main body of the jig, and is used to remove the main body of the jig located in the inter-layer truss.

[0007] Furthermore, the main body of the frame includes a base plate fixed to the end face of the lower truss and a top block connected to the end face of the upper truss. Square vertical tubes are detachably installed at the four corners of the base plate, and inner square tubes are slidably installed on each square vertical tube. A connecting beam plate fixed to the four corners of the top block is installed at the top end of the inner square tube. The top block has a cross-shaped structure, and a spiral top support fixed to the base plate is installed at the center of the top block.

[0008] Furthermore, each of the two square risers is provided with two reinforcing rods on one side, and a connection point is provided at the center of the intersection of the two reinforcing rods. Each connection point is detachably connected to the spiral jack.

[0009] Furthermore, the removal mechanism includes an adjustment component installed relative to the climbing mold frame and at the correspondingly distributed connection point positions, and a moving block disposed at the inner end of the climbing mold frame. The adjustment component includes a first hydraulic cylinder and a second hydraulic cylinder. By sequentially adjusting the length and angle of the first hydraulic cylinder and the second hydraulic cylinder, the main body of the jig is moved out of the interlayer truss and into the climbing formwork.

[0010] Furthermore, each of the first and second hydraulic cylinders is provided with a corresponding rotating shaft at one end of the corresponding body of the tire frame. A motor a is provided on the rotating shaft located on the first hydraulic cylinder. An electromagnetic clutch is provided on the motor a at the position connected to the rotating shaft. A first support crossbar and a second support crossbar are arranged vertically on the moving block at the positions corresponding to the first and second hydraulic cylinders. A notch for separation is provided at the end of the first hydraulic cylinder corresponding to the first support crossbar.

[0011] Furthermore, the moving block is vertically slidably connected to the corresponding end face of the climbing mold frame, and a screw is vertically connected through the end face of the moving block, with a motor b for use at the bottom end of the screw.

[0012] Furthermore, the end faces of the square riser and the inner square tube are provided with multiple sets of equally spaced fixing screw holes, and each fixing screw hole is provided with a fastening bolt for fixed connection.

[0013] The beneficial effects of this invention are reflected in: This invention, due to the inclusion of a climbing formwork and a removal mechanism, allows the main body of the formwork located in the inter-layer truss to be removed, facilitating subsequent climbing of the formwork main body. This avoids the problem of repeated disassembly and assembly of traditional formwork, significantly improving construction efficiency and safety. It is suitable for construction in space-constrained or continuous truss structures. Furthermore, the formwork main body with variable height allows for adaptability adjustments based on the height of the inter-layer truss. After lowering the formwork main body to its lowest horizontal height, it facilitates removal of the formwork main body from the inter-layer truss at a fixed height, making operation convenient.

[0016] 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 a part of the embodiments of the present invention, and not all of them. Unless otherwise specified, the embodiments and features in the embodiments of this application can be combined with each other. 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.

[0017] Please see Figure 1-5 This invention discloses a movable support frame, comprising a frame body fixed to an inter-layer truss, and further comprising: Climbing formwork 1 is located on the outer side of the truss and is used to support the vertical climbing of the main body of the formwork. The removal mechanism 2 is movably mounted on the climbing formwork 1 and connected to the main body of the jig, and is used to remove the main body of the jig located in the inter-layer truss.

[0018] In practice, by using the lifting formwork 1, which is laid out and installed on the outside of the truss, and the removal mechanism 2, the main body of the jig located in the inter-layer truss can be removed. The jig body is then vertically lifted within the lifting formwork 1, allowing the jig body located in the lower truss to be lifted and moved to the upper inter-layer truss. This avoids the problem of repeated disassembly and assembly of traditional jigs, significantly improving construction efficiency and safety. It is suitable for construction of space-constrained or continuous trusses.

[0019] In one embodiment, the main body of the frame includes a base plate 3 fixed to the end face of the lower truss and a top block 4 connected to the end face of the upper truss. Square vertical tubes 5 are detachably mounted at the four corners of the base plate 3, and inner square tubes 6 are slidably mounted on each square vertical tube 5. A connecting beam plate 7, fixed to the four corners of the top block 4, is mounted at the top of each inner square tube 6. The top block 4 has a cross-shaped structure, and a spiral jacking device 8 fixed to the base plate 3 is mounted at the center of the top block 4. This design, using the combination of square vertical tubes 5 and inner square tubes 6 at the four corners of the base plate 3 and top block 4, allows the spiral jacking device 8, bolted to the base plate 3, to move the top block 4 upwards. This causes the top surface of the top block 4 to abut against the end face of the corresponding truss, and, supported by the connecting beam plate 7 welded to the end face of the top block 4, simultaneously moves the inner square tube 6 upwards relative to the square vertical tube 5. This allows the main body of the frame to be adjusted for suitability according to the height of the inter-layer truss.

[0020] In one embodiment, two reinforcing rods 9 are provided on one side of each pair of square risers 5, and a connection point is provided at the center of the intersection of the two reinforcing rods 9. Each connection point is detachably connected to the spiral jacking device 8. With this design, by welding two reinforcing rods 9 to one side of each pair of square risers 5 at an intersection, and by using a perforated mounting plate to detachably connect the connection point of the two reinforcing rods 9 to the spiral jacking device 8, the two reinforcing rods 9 are distributed in an "X" shape, which effectively improves the overall strength of the jig body. On the other hand, the modular structure allows for reuse and avoids the material waste of traditional jigs.

[0021] In one embodiment, the removal mechanism 2 includes an adjustment component 21 installed relative to the climbing mold frame 1 and at the correspondingly distributed connection point positions, and a moving block 22 disposed at the inner end of the climbing mold frame 1. The adjustment component 21 includes a first hydraulic cylinder 211 and a second hydraulic cylinder 212. By sequentially adjusting the length and angle of the first hydraulic cylinder 211 and the second hydraulic cylinder 212, the main body of the jig is moved out of the interlayer truss and into the climbing formwork 1. This design utilizes an adjustment assembly 21 installed at a connection point relative to the climbing formwork 1, and a vertically movable moving block 22 within the climbing formwork 1. The adjustment component 21 includes a first hydraulic cylinder 211 and a second hydraulic cylinder 212. In the initial state, the first hydraulic cylinder 211 and the second hydraulic cylinder 212 are connected to the moving block 22 to support the main body of the jig on the climbing mold frame 1 and fix the main body of the jig in the interlayer truss. In the moving state, the first hydraulic cylinder 211 and the second hydraulic cylinder 212 are adjusted in sequence to move the main body of the jig from the interlayer truss into the climbing mold frame 1. Then, under the action of the moving block 22, it moves vertically to the upper interlayer truss. The first hydraulic cylinder 211 and the second hydraulic cylinder 212 are adjusted again to move the main body of the jig into the corresponding interlayer truss for fixed support.

[0022] In one embodiment, the first hydraulic cylinder 211 and the second hydraulic cylinder 212 are each provided with a corresponding rotating shaft at one end of the corresponding body of the frame. A motor a23 is provided on the rotating shaft located on the first hydraulic cylinder 211. An electromagnetic clutch is provided on the motor a23 at the position connected to the rotating shaft. A first support crossbar 24 and a second support crossbar 25 are arranged vertically on the moving block 22 at the positions corresponding to the first hydraulic cylinder 211 and the second hydraulic cylinder 212. A notch for separation is provided at the end of the first hydraulic cylinder 211 corresponding to the first support crossbar 24. This design utilizes a rotating shaft mounted on one end of the first hydraulic cylinder 211 and the second hydraulic cylinder 212 near the main body of the frame, and a motor a23 mounted on the rotating shaft. First, the motor a23 is started, actively rotating the first hydraulic cylinder 211 upwards. This allows the first hydraulic cylinder 211 to separate from the first support crossbar 24 on the moving block 22 via a notch on its movable end. At this point, the second hydraulic cylinder 212 is telescopically adjusted, moving the main body of the frame located in the interlayer truss. Subsequently, under the action of the motor a23, the first hydraulic cylinder 211 is rotated downwards while simultaneously controlling the first hydraulic cylinder... The extension and retraction adjustment of the pressure cylinder 211 causes the first hydraulic cylinder 211 to engage with the first support crossbar 24 on the moving block 22, stabilizing the main body of the jig frame within the climbing mold frame 1 and connecting it with the moving block 22. At this time, the moving block 22 is moved along the height direction of the climbing mold frame 1 to the upper truss position. Then, the motor a23 and the first hydraulic cylinder 211 are operated in sequence to separate the first hydraulic cylinder 211 from the first support crossbar 24. Through the extension and retraction adjustment of the second hydraulic cylinder 212, the main body of the jig frame is moved into the corresponding interlayer truss, thus completing the climbing operation of the main body of the jig frame.

[0023] It should be noted that the electromagnetic clutch connected to the shaft of the motor a23 and the first hydraulic cylinder 211 is energized and engaged when the motor a23 actively rotates and drives the first hydraulic cylinder 211 to rotate, thereby attracting the friction plate to transmit torque; when the first hydraulic cylinder 211 is in the extension and retraction adjustment control, the electromagnetic clutch is de-energized and disengaged, the spring returns to its original position, and the power transmission is cut off.

[0024] To further explain, before using the removal mechanism 2 to move the main body of the jig out, climb, or move in, the spiral jack 8 on the jig main body will be controlled to lower the jack block 4, so that the jig main body leaves an operating gap in the corresponding interlayer truss, which facilitates the removal or movement of the jig main body.

[0025] In one embodiment, the moving block 22 is vertically slidably connected to the corresponding end face of the climbing mold frame 1. A screw 26 is vertically threaded through the end face of the moving block 22, and a motor b is connected to the bottom end of the screw 26. With this design, by using the moving block 22, which is limited and slidable by a slot on the end face of the climbing mold frame 1, and the screw 26, which is vertically slotted and threaded on the moving block 22, the motor b connected to the screw 26 is activated, causing the screw 26 to rotate. This allows the moving block 22, which is threaded on the screw 26, to move vertically in a straight line at the slotted position on the end face of the climbing mold frame 1, thus realizing the climbing operation of the mold frame body.

[0026] It should be noted that the moving block 22 in this application can be vertically slotted to accommodate two parallel twin-screw structures, and motors can be installed at each end of the twin-screw structures for matching use, resulting in higher transmission efficiency, stronger load-bearing capacity, and the twin screws can share the load.

[0027] In one embodiment, the end faces of both the square riser 5 and the inner square tube 6 are provided with multiple sets of equidistantly distributed fixing screw holes 10, and each fixing screw hole 10 is correspondingly provided with a fastening bolt 11 for fixed connection. With this design, the multiple sets of fixing screw holes 10 correspondingly machined on the square riser 5 and the inner square tube 6 are driven to move relative to each other under the action of the spiral support 8. At this time, the fastening bolts 11 are used to limit and lock the connection on the connected fixing screw holes 10, which further enhances the connection strength and stability of the square riser 5 and the inner square tube 6.

[0028] It should be noted that if the embodiments of the present invention involve directional indicators (such as up, down, left, right, front, back, etc.), the directional indicators are only used to explain the relative positional relationship and movement of the components in a certain specific posture (as shown in the figure). If the specific posture changes, the directional indicators will also change accordingly.

[0029] Furthermore, if the embodiments of this invention involve descriptions such as "first" or "second," these descriptions are for descriptive purposes only and should not be construed as indicating or implying their relative importance or implicitly specifying the number of technical features indicated. Therefore, a feature defined with "first" or "second" may explicitly or implicitly include at least one of those features. Additionally, the technical solutions of the various embodiments can be combined with each other, but this must be based on the ability of those skilled in the art to implement them. If the combination of technical solutions is contradictory or impossible to implement, it should be considered that such a combination of technical solutions does not exist and is not within the scope of protection claimed by this invention.

[0030] Additionally, "multiple" refers to two or more.

[0031] The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present invention should be included within the protection scope of the present invention.
