Description

Technical Field

[0001] This invention relates to the field of construction equipment technology, and in particular to an adjustable slope, highly stable climbing and attachment device. Background Technology

[0002] In the field of high-rise building construction, climbing scaffolding (referred to as "climbing formwork") has significantly reduced manpower and material consumption due to its advantages of being able to be used throughout the entire construction process after a single assembly, requiring no repeated disassembly and assembly, and not being limited by building height. Compared with traditional scaffolding, it has achieved a significant improvement in construction efficiency and cost control, and has become an indispensable key equipment in high-rise building construction. The stable operation and safety performance of climbing formwork depend on the reliable connection between the attachment device and the building structure. Among them, the inclined tension attachment frame, as the core component that provides the wall support and lifting bracket attachment position, directly determines the construction safety and applicability of the climbing formwork.

[0003] However, in the actual construction of high-rise buildings, traditional climbing formwork attachment devices generally suffer from insufficient adjustability due to factors such as building design requirements (e.g., building cross-sectional shrinkage, facade tilt) and construction errors. On the one hand, the connection position between the attachment device and the building structure is difficult to adjust flexibly according to changes in the building cross-section, resulting in the climbing formwork experiencing climbing obstruction and uneven stress at locations where the building shape changes. On the other hand, the tilt angle of traditional attachment devices is fixed and cannot adapt to building facades with different tilt angles. This not only limits the applicable range of the climbing formwork but may also cause stress concentration at the attachment points due to forced adaptation, leading to safety hazards. Summary of the Invention

[0004] The present invention aims to at least partially solve one of the problems existing in the prior art. To this end, the present invention proposes a climbing attachment device with adjustable slope, high stability and adaptability to changes in building cross-section.

[0011] In some embodiments, the synchronous locking mechanism includes a left pressure plate and a right pressure plate disposed on both sides of the two channel steels. A first bolt and a second bolt are respectively disposed on the left pressure plate. The first bolt passes through the first hinge shaft and the right pressure plate and is threaded to a first locking nut. The second bolt passes through the second hinge shaft and the right pressure plate and is threaded to a second locking nut. Horizontal through slots are provided on both sides of the two channel steels. Extension columns movable in the horizontal through slots are provided on both sides of the U-shaped seat. The left pressure plate and the right pressure plate can respectively press against the corresponding extension columns. The screw fixing block is provided with a screw hole for the positive and negative threaded screws to be threaded. The axis of the fourth hinge shaft is provided with a through hole communicating with the screw hole. Pressing columns are provided on the inner sides of the left pressure plate and the right pressure plate. The two pressing columns are respectively inserted into the corresponding through holes and pressed against the positive and negative threaded screws.

[0016] Compared with the prior art, the beneficial effects of the present invention are:

[0017] 1. This device, by setting an adjustment and control mechanism between the attachment device base and the sliding support, can flexibly control the back-and-forth sliding of the base relative to the sliding support. Combined with the inclined pull control mechanism between the support connecting plate and the base, the tilt angle of the support connecting plate can be precisely adjusted. This dual adjustment structure can effectively adapt to complex construction scenarios such as building section shrinkage and facade tilt, completely solving the problem of the climbing formwork being obstructed due to insufficient adjustment capacity of traditional attachment devices, and greatly expanding the application range of the climbing formwork.

[0018] 2. The device employs two sets of rolling trolleys symmetrically positioned at the front and rear ends of the base bottom. This ensures the stability of the base during sliding and enhances the overall load-bearing capacity of the structure. Simultaneously, the synchronous locking mechanism can lock the support connecting plate, sliding support, and adjustment control mechanism to the attachment device base, achieving coordinated fixation of each connecting component. This avoids the risk of uneven force distribution or loosening caused by independent locking, significantly improving the structural stability of the climbing frame during climbing and operation, and effectively reducing safety hazards.

[0027] The following detailed description provides various embodiments or examples for carrying out the present invention. Of course, these are merely embodiments or examples and are not intended to be limiting. Additionally, repeated reference numerals, such as repeated numbers and / or letters, may be used in different embodiments. These repetitions are for the purpose of simple and clear description of the invention and do not represent a specific relationship between the different embodiments and / or structures discussed.

[0028] like Figures 1-8 The adjustable slope high-stability climbing attachment device shown includes an attachment device base 1, on which rolling trolleys 2 and sliding supports 3 are respectively arranged. Two sets of rolling trolleys 2 are respectively fixed to the front and rear ends of the bottom of the attachment device base 1. The sliding supports 3 are fixed to the concrete surface 10. The attachment device base 1 can slide back and forth relative to the sliding supports 3. An adjustment control mechanism is also connected between the attachment device base 1 and the sliding supports 3. The adjustment control mechanism is used to control the back and forth sliding of the attachment device base 1 relative to the sliding supports 3. A support connecting plate 4 for connecting with the building climbing frame is hinged to the front end of the attachment device base 1. An inclined pull control mechanism is also connected between the support connecting plate 4 and the attachment device base 1. The inclined pull control mechanism is used to control the inclination angle between the support connecting plate 4 and the attachment device base 1. A synchronous locking mechanism is also provided on the attachment device base 1. The synchronous locking mechanism is used to synchronously lock the support connecting plate 4, the sliding supports 3 and the adjustment control mechanism on the attachment device base 1.

[0029] First, the sliding support 3 is firmly fixed to the building concrete surface 10 using anchor bolts and other connectors, serving as the load-bearing foundation for the entire device. The attachment device base 1 forms a rolling engagement with the sliding support 3 through two sets of rolling trolleys 2 at its front and rear ends, ensuring that the base can move smoothly along the sliding support and providing structural support for subsequent position adjustments. By controlling the adjustment control mechanism between the attachment device base 1 and the sliding support 3, the base is driven to slide precisely along the sliding support in the front and rear directions until it moves to a position that matches the connection requirements of the building climbing frame. This adapts to changes in building cross-section such as shrinkage, solving the adaptation problem caused by the fixed connection position of traditional devices. Using the support connecting plate 4 hinged at the front end of the attachment device base 1, the tilt angle of the support connecting plate is adjusted by controlling the diagonal pull control mechanism between the support connecting plate and the base, so that the connecting surface of the support connecting plate is completely fitted with the connecting end of the building climbing frame. This achieves adaptation to building facades with different tilt angles and avoids force deviations between the climbing frame and the attachment device. Once the position and tilt angle are adjusted to the correct positions, the synchronous locking mechanism on the attachment device base 1 simultaneously locks the support connecting plate 4, sliding support 3, and adjustment control mechanism onto the attachment device base, forming a rigid whole. This prevents relative displacement or loosening after adjustment and ensures that the attachment device maintains a stable load-bearing state during the climbing and operation of the scaffold. After the building climbing scaffold is fixedly connected to the support connecting plate 4, the device provides reliable attachment support for the climbing scaffold through its rigid locking structure. When the climbing scaffold needs to climb upwards, the synchronous locking mechanism is first unlocked, and the above position and tilt angle adjustment process is repeated. After adapting to the new building structure at the new height, the mechanism is locked again to ensure stable climbing of the scaffold throughout the entire process.

[0030] Thus, through the dual adjustment design of the adjustment control mechanism and the inclined control mechanism, the front and rear positions of the attachment device base 1 relative to the sliding support 3 are adjustable, and the connection angle of the support connecting plate 4 relative to the attachment device base 1 is flexibly adjustable. This can adapt to complex building forms such as building section shrinkage and facade inclination, and can also accommodate the adaptation requirements caused by construction errors. It completely solves the problems of climbing formwork being obstructed and unevenly stressed due to insufficient adjustment capacity of traditional attachment devices, and greatly expands the applicable scenarios of climbing formwork.

[0031] In this invention, the attachment device base 1 includes two channel steels 21 arranged symmetrically on the left and right, and a connecting pipe 22 connecting the two channel steels 21; thus, the two channel steels 21 serve as the core load-bearing beams of the base, and their channel-shaped structure can provide sufficient bending and torsional section modulus, and can stably bear the vertical load, horizontal load and overturning moment transmitted from the building climbing frame through the support connecting plate 4; the connecting pipe 22 is horizontally welded between the two channel steels 21, integrating the two independent channel steels into an integral frame structure, ensuring that the load is evenly transmitted between the two channel steels and avoiding the concentration of force on a single channel steel.

[0032] See Figure 1 , Figure 2 As shown, the lower end of the support connecting plate 4 is provided with a first hinge shaft 31. The first hinge shaft 31 is a hollow structure and is rotatably disposed within the two channel steels 21. The inclined pull control mechanism includes a connecting steel pipe 32. Both ends of the connecting steel pipe 32 are threadedly connected with pull rods 33. One of the two pull rods 33 is a positive thread and the other is a negative thread. The upper pull rod 33 is hinged to the upper end of the support connecting plate 4. The lower pull rod 33 is provided with a second hinge shaft 34. The second hinge shaft 34 is a hollow structure and is rotatably disposed within the two channel steels 21.

[0033] Thus, the lower end of the support connecting plate 4 is rotatably mounted within the two channel steels 21 via the first hinge shaft 31 of the hollow structure, forming a stable hinge fulcrum. This ensures that the support connecting plate can rotate flexibly around the first hinge shaft, providing a mechanical basis for tilt angle adjustment. In the inclined control mechanism, the lower end of the pull rod 33 is also rotatably mounted within the two channel steels 21 via the second hinge shaft 34 of the hollow structure, forming a symmetrical double-hinged support system with the first hinge shaft. This ensures a reliable connection between the inclined control mechanism and the base, and provides space for adaptive adjustment of the pull rod angle, avoiding jamming or stress concentration during adjustment.

[0034] The connecting steel pipe 32 of the inclined control mechanism is threaded at both ends with two pull rods 33 of positive and negative thread structures, forming a bidirectional adjusting screw assembly. When it is necessary to adjust the tilt angle of the support connecting plate 4, the connecting steel pipe 32 is rotated. Since the threads at both ends rotate in opposite directions, the two pull rods will simultaneously retract into the connecting steel pipe or extend outward, achieving precise extension and retraction of length. If it is necessary to increase the tilt angle of the support connecting plate, the connecting steel pipe is rotated to extend the pull rods. Through the pulling force of the upper pull rod on the upper end of the support connecting plate 4, the support connecting plate is driven to rotate counterclockwise around the first hinge axis. If it is necessary to decrease the tilt angle, the connecting steel pipe is rotated in the opposite direction to shorten the pull rods. Under the action of the climbing frame connection force or its own weight, the support connecting plate rotates clockwise around the first hinge axis until the angle is adapted to the building facade.

[0035] See Figure 2 , Figure 4 As shown, the sliding support 3 includes a U-shaped seat 41. Upper rollers 42 that roll on the channel steel 21 are provided on both the left and right sides of the upper end of the U-shaped seat 41. A fixing screw 43 fixed to the concrete surface 10 is provided at the bottom of the U-shaped seat 41. The fixing screw 43 fixes the U-shaped seat 41 with several nuts 44.

[0036] Thus, the U-shaped seat 41 of the sliding support 3 is connected to the building concrete surface 10 through the fixing screw 43 at the bottom. Several nuts 44 are used to lock the U-shaped seat in both directions (the nuts are respectively attached to the bottom of the U-shaped seat and one side of the concrete surface), firmly fixing the U-shaped seat and forming the load-bearing foundation of the entire device. The upper rollers 42 on the left and right sides of the upper end of the U-shaped seat 41 respectively roll in contact with the lower flanges of the two channel steels 21 of the attachment device base 1, so that the base and the U-shaped seat form a rolling engagement through the rollers. This not only realizes the support of the base, but also transfers the vertical and horizontal loads transmitted by the climbing frame to the concrete surface layer by layer through the rollers, U-shaped seat and fixing screw, ensuring that the load transfer path is clear and reliable.

[0037] When the adjustment and control mechanism drives the attachment device base 1 to slide back and forth relative to the sliding support 3, the two channel steels 21 roll along the upper rollers 42 on both sides of the U-shaped seat 41. The rolling friction of the rollers replaces the traditional sliding friction, which greatly reduces the frictional resistance when the base slides and avoids jamming or stuck phenomena. At the same time, the upper rollers symmetrically arranged on the left and right correspond one-to-one with the double channel steels 21 to ensure that the force is balanced during the sliding process of the base and the center of gravity is always kept in the center position, preventing the base from shifting or tilting, providing a stable positional basis for tilt angle adjustment, and avoiding the impact of sliding deviation on the tilt angle adaptation accuracy.

[0038] See Figure 2 , Figure 8 As shown, the adjustment and control mechanism includes a lead screw fixing tube 51. A third hinge shaft 52 is provided at one end of the lead screw fixing tube 51, and a positive and negative threaded lead screw 53 is threaded to the other end. The third hinge shaft 52 is hinged to the U-shaped seat 41. The other end of the positive and negative threaded lead screw 53 is threaded to a lead screw fixing block 54. A fourth hinge shaft 55 is provided on both the left and right sides of the lead screw fixing block 54. The fourth hinge shaft 55 is hinged to the two channel steels 21.

[0039] One end of the lead screw fixing tube 51 of the adjustment and control mechanism is hinged to the U-shaped seat 41 of the sliding support 3 through the third hinge shaft 52. It can only swing around the hinge shaft and cannot rotate actively, forming a fixed constraint end. The other end of the lead screw fixing tube 51 is tightly connected to the positive and negative threaded lead screw 53 through threads. The other end of the positive and negative threaded lead screw is also connected to the lead screw fixing block 54 through threads. The fourth hinge shafts 55 on the left and right sides of the lead screw fixing block are respectively hinged to the two channel steels 21 of the attachment device base 1.

[0040] Since the screw fixing tube 51 is hinged and fixed and cannot rotate, when the screw 53 is rotated, the positive and negative threads at both ends will generate relative threaded movement with the screw fixing tube 51 and the screw fixing block 54, respectively.

[0041] If the screw 53 is rotated clockwise, based on the thread direction design, the screw fixing tube 51 and the screw fixing block 54 will move away from each other along the screw axis. The screw fixing block 54 applies a backward thrust to the two channel steels 21 through the fourth hinge shaft 55, which drives the attachment device base 1 to roll smoothly backward along the upper roller 42 of the U-shaped seat 41.

[0042] If the forward and reverse threaded screw 53 is rotated counterclockwise, the screw fixing tube 51 and the screw fixing block 54 will move closer to each other along the screw axis. The screw fixing block 54 applies a forward pulling force to the channel steel 21 through the fourth hinge shaft 55, causing the base to roll forward along the roller.

[0043] When the base moves, the rolling trolley 2 at the bottom and the upper roller 42 of the U-shaped seat 41 form a double rolling engagement, which efficiently converts the driving force of the threaded transmission into the linear displacement of the base. The rolling friction greatly reduces the resistance to movement and avoids adjustment jamming.

[0044] In this invention, the synchronous locking mechanism includes a left pressure plate 61 and a right pressure plate 62 disposed on both sides of the two channel steels 21. A first bolt 63 and a second bolt 64 are respectively disposed on the left pressure plate 61. The first bolt 63 passes through a first hinge shaft 31 and the right pressure plate 62, and is threadedly connected to a first locking nut 65. The second bolt 64 passes through a second hinge shaft 34 and the right pressure plate 62, and is threadedly connected to a second locking nut 66. Horizontal through slots 67 are provided on both sides of the two channel steels 21. The U-shaped seat 41... Both sides of the device are provided with extension columns 68 that can move within the horizontal through groove 67. The left pressure plate 61 and the right pressure plate 62 can respectively press against the corresponding extension columns 68. The screw fixing block 54 is provided with a screw hole for the threaded connection of the positive and negative threaded screws 53. The axis of the fourth hinge shaft 55 is provided with a through hole 69 that communicates with the screw hole. The inner sides of the left pressure plate 61 and the right pressure plate 62 are provided with clamping columns 610. The two clamping columns 610 are respectively inserted into the corresponding through holes 69 and press against the positive and negative threaded screws 53.

[0045] Specifically, after the position of the attachment device base 1 and the tilt angle of the support connecting plate 4 are adjusted to the correct position, the locking operation begins. The first bolt 63 on the left pressure plate 61 is passed through the hollow structure of the first hinge shaft 31, then through the right pressure plate 62, and the first locking nut 65 is tightened. At the same time, the second bolt 64 is passed through the hollow structure of the second hinge shaft 34, then through the right pressure plate, and the second locking nut 66 is tightened. Through the locking force of the bolts and nuts, the left and right pressure plates are clamped together, which on the one hand firmly locks the first hinge shaft 31 and the second hinge shaft 34 into the two channel steels 21, restricting their rotational freedom and preventing the support connecting plate 4 and the inclined control mechanism from adjusting the tilt angle; on the other hand, during the clamping process, the inner sides of the left and right pressure plates are pressed against the side walls of the channel steels, simultaneously pressing against the extension columns 68 on both sides of the U-shaped seat 41, fixing the extension columns into the horizontal through groove 67 through friction, thereby locking the relative position of the attachment device base and the sliding support 3 and preventing the base from sliding back and forth.

[0046] While the left and right pressure plates clamp, the inner clamping pin 610 is simultaneously inserted into the through hole 69 of the fourth hinge shaft 55 until it presses against the surface of the positive and negative threaded rod 53. One end of the clamping pin 610 pressing against the surface of the positive and negative threaded rod 53 is fitted with rubber. Since the fourth hinge shaft is fixedly connected to the threaded rod fixing block 54, and the threaded rod fixing block engages with the positive and negative threaded rod via threads, the clamping force of the clamping pin on the positive and negative threaded rod restricts the rotational freedom of the threaded rod, preventing loosening of the threads due to vibration, external forces, etc., thereby locking the extension and retraction state of the adjustment control mechanism.

[0047] Furthermore, a third bolt 71 is provided at the rear end of both channel steels 21. A connecting pressure plate 72 is connected to the rear end of the left pressure plate 61 and the right pressure plate 62. A connecting groove 73 is provided on the connecting pressure plate 72 at intervals on the left and right sides. The rear ends of the left pressure plate 61 and the right pressure plate 62 can be inserted into the corresponding connecting groove 73. The third bolt 71 passes through the connecting pressure plate 72 and is threaded to a third locking nut 75. An avoidance through hole 74 is provided on the connecting pressure plate 72 for the positive and negative threaded rods 53 to pass through.

[0048] Specifically, the third bolt 71 pre-set at the rear end of the two channel steels 21 provides a fixed support point for the connecting pressure plate 72. The left and right spaced connecting grooves 73 on the connecting pressure plate are precisely matched with the rear ends of the left pressure plate 61 and the right pressure plate 62, ensuring that the rear ends of the left and right pressure plates can be smoothly inserted into the corresponding connecting grooves. The clearance through hole 74 on the connecting pressure plate corresponds to the installation position of the positive and negative threaded rod 53, which not only avoids spatial interference between the connecting pressure plate and the adjustment and control mechanism, but also ensures normal extension and retraction adjustment of the threaded rod, achieving seamless compatibility with the preceding structure.

[0049] During operation, the connecting groove 73 of the connecting pressure plate 72 is aligned with the rear ends of the left and right pressure plates and inserted. The third bolt 71 passes through the connecting pressure plate 72, and the third locking nut 75 is tightened. The locking force of the third bolt drives the connecting pressure plate to press towards the channel steel, thereby causing the rear ends of the left pressure plate 61 and the right pressure plate 62 to clamp towards the middle synchronously. This forms a "symmetrical locking" structure with the first bolt 63 and the second bolt 64 at the front end, extending the clamping force of the left and right pressure plates on the channel steel 21 from the front end to the rear end, forming a uniform clamping force along the entire length. The connecting pressure plate 72 is rigidly connected to the left and right pressure plates through the connecting groove 73, integrating the left and right pressure plates into a single frame, preventing warping or loosening of the pressure plates on one side due to uneven force. At the same time, the clearance through hole 74 provides room for the movement of the positive and negative threaded rod 53, ensuring that the rod can pass through normally in both the adjustment and locking states without affecting the function of the adjustment and control mechanism.

[0050] In this invention, a fixing plate 81 extending in the left-right direction is provided at the upper end of the U-shaped seat 41. Side plate seats 82 extending downward are provided on both the left and right sides of the fixing plate 81. A transverse groove 83 is provided on the inner side of both side plate seats 82. A clamping block 84 that can press against the left pressure plate 61 or the right pressure plate 62 slides in the transverse groove 83. A drive plate 85 is also provided at the upper end of the fixing plate 81. The upper end of the fixing screw 43 passes through the fixing plate 81 and the drive plate 85 respectively and is threadedly connected to a fourth locking nut 86. A transmission assembly is connected between the drive plate 85 and the clamping block 84. When the fourth locking nut 86 presses the drive plate 85, the clamping block 84 can be driven to move inward through the transmission assembly, thereby pressing the left pressure plate 61 or the right pressure plate 62.

[0051] Furthermore, the transmission assembly includes a transmission pressure plate 91 located at the lower end of the drive plate 85, a vertical groove 92 communicating with the transverse groove 83 at the upper end of the side plate seat 82, a first guide slope 93 at the lower side of the transmission pressure plate 91, a second guide slope 94 cooperating with the first guide slope 93 at one end of the clamping block 84 located in the transverse groove 83, and an upper clamping block 95 capable of clamping against the upper end of the channel steel 21 at the lower end of the drive plate 85.

[0052] Specifically, the fixed plate 81 at the upper end of the U-shaped seat 41 is rigidly connected to the left and right side plate seats 82 to form a stable support frame; the transverse groove 83 on the inner side of the side plate seat 82 allows the clamping block 84 to slide laterally, and the vertical groove 92 at the upper end is connected to the transverse groove to provide vertical movement space for the transmission pressure plate 91; the transmission pressure plate 91 at the lower end of the drive plate 85 and the clamping block 84 are respectively provided with a first guide slope 93 and a second guide slope 94 to ensure accurate power transmission; the upper clamping pressure block 95 at the lower end of the drive plate is precisely aligned with the upper end face of the channel steel 21, and the fixing screw 43 passes through the fixed plate and the drive plate in sequence and then cooperates with the fourth locking nut 86. The overall structure is seamlessly adapted to the preceding left pressure plate 61, right pressure plate 62, channel steel 21 and other components, without interfering with the adjustment and locking functions.

[0053] During operation, the drive plate 85 is initially positioned by the fixing screw 43, the transmission pressure plate 91 is located at the upper end of the vertical groove 92, the clamping block 84 is in the horizontal groove 83 and does not contact the left and right pressure plates, and the upper clamping block 95 does not contact the upper end of the channel steel. Then tighten the fourth locking nut 86, the drive plate 85 presses down vertically, and simultaneously drives the transmission pressure plate 91 to extend downward into the vertical groove 92, and the upper pressing block 95 moves closer to the upper end of the channel steel 21; the first guide slope 93 of the transmission pressure plate 91 contacts the second guide slope 94 of the pressing block 84 and generates relative sliding, using the slope principle to convert the vertical pressing force into a horizontal thrust, pushing the pressing block 84 to slide inward along the horizontal groove 83; the two pressing blocks 84 simultaneously press the left pressure plate 61 and the outer side of the right pressure plate 62, applying a lateral pressing force; at the same time, the upper pressing block 95 presses the upper end face of the channel steel 21, applying vertical pressure, and finally forming a double locking of "lateral pressing of the left and right pressure plates + vertical pressing of the channel steel", so that the left and right pressure plates are completely in contact with the channel steel, the extension column 68, and the pressing column 610.

[0054] Furthermore, a circular hole 100 is provided on the side of the clamping block 84 near the channel steel 21, and a spring 101 and a ball bearing 102 are sequentially arranged in the circular hole 100.

[0055] Therefore, when the device is in the position adjustment or tilt adjustment stage (without tightening the fourth locking nut 86), the synchronous locking mechanism is not fully clamped. At this time, under the preload of the spring 101, the ball 102 of the top clamping block 84 always abuts against the outer wall of the left and right pressure plates. When the adjustment control mechanism drives the attachment device base 1 to slide back and forth, the left and right pressure plates move synchronously with the channel steel 21. The ball 102 forms a rolling fit with the outer wall of the pressure plate, which transforms the traditional sliding friction into rolling friction, greatly reducing the resistance when the pressure plate moves, avoiding jamming or wear between the pressure plate and the top clamping block, and ensuring smooth sliding adjustment of the base.
