Description

Technical Field

[0001] This utility model relates to the technical field of rigid frame support devices, and in particular to a portal rigid frame support device with adaptive height adjustment. Background Technology

[0002] Portal frame lightweight building structures are characterized by simple stress distribution, clear force transmission path, quick component fabrication, easy factory processing, and short construction cycle. Therefore, they are widely used in industrial, commercial, and cultural and entertainment public facilities. As a common support device, portal frame supports can provide stable support.

[0003] In practical applications, the existing portal frame support devices have relatively complete structures and functions, which can meet basic usage requirements. However, the following problems still exist:

[0004] In actual use, the height of the portal frame needs to be adjusted according to the actual situation. The traditional adjustment method requires the use of hoisting equipment to limit the position after the adjustment is completed, and then other tools are used to drill holes and fix bolts, which makes the overall adjustment and fixing method cumbersome and inconvenient.

[0005] Therefore, this utility model provides a portal frame support device with adaptive height adjustment. Utility Model Content

[0006] The purpose of this invention is to overcome the shortcomings of the existing technology and provide an adaptive height-adjustable portal frame support device.

[0007] To achieve the above objectives, the present invention adopts the following technical solution: an adaptive height-adjustable portal frame support device, comprising a base plate, wherein a frame is fixedly connected to the top of the base plate; an adjustment limiting structure is provided on the inner walls of both sides of the frame, the adjustment limiting structure comprising sliding grooves formed on both sides of the frame, auxiliary sliding grooves formed on the inner walls of both sides of the sliding grooves, two rows of rectangular blocks are symmetrically fixedly connected to one side of the frame, and sliding blocks are slidably arranged on the inner walls of the sliding grooves; a disassembly limiting structure is provided on the top of the sliding blocks, the disassembly limiting structure comprising an adjustment frame, and a crossbar is fixedly connected to the top of the adjustment frame.

[0008] In a preferred embodiment, auxiliary sliders are fixedly connected to both sides of the outer surface of the sliding block. The auxiliary sliders are slidably disposed on the inner wall of the auxiliary groove. A U-shaped plate is fixedly connected to the bottom of the outer surface of the sliding block. A rotating rod is rotatably connected between the two sides of the inner wall of the U-shaped plate. A rotating block is fixedly connected to the outer surface of the rotating rod. A limit plate is fixedly connected to the outer surface of the rotating block. A torsion spring is sleeved on the outer surface of the rotating rod. The two ends of the torsion spring are fixedly connected to the outer surface of the U-shaped plate and the outer surface of the rotating block, respectively.

[0009] The technical effect of adopting the above-mentioned further solution is as follows: Under the action of the rotating rod and the rotating block, the limiting plate can be driven to rotate. Then, in conjunction with the rectangular stop, when the sliding block moves upward, the rectangular stop can block the limiting plate, causing the limiting plate to rotate. Then, when the limiting plate separates from the rectangular stop and the sliding block moves to the upper position, the limiting plate can be reset under the action of the torsion spring. Then, in conjunction with the rectangular stop, it will not rotate downward, thus providing auxiliary limiting for the sliding block and limiting the sliding block.

[0010] In a preferred embodiment, a rectangular frame is fixedly connected to the top of the outer surface of the sliding block, a rectangular block is engaged with the inner wall of the rectangular frame, the top of the rectangular block is fixedly connected to the bottom of the adjusting frame, a first screw hole is provided on one side of the rectangular frame, a second screw hole is provided on the inner wall of the rectangular block, and a threaded rod is threadedly connected to the inner walls of the first and second screw holes.

[0011] The technical effect of adopting the above-mentioned further solution is that, under the action of the rectangular card block and the rectangular card frame, the adjustment frame and the sliding block can be disassembled and assembled with assistance, and the adjustment frame can be disassembled and replaced according to actual usage needs.

[0012] In a preferred embodiment, an L-shaped plate is fixedly connected to one side of the outer surface of the adjustment frame, a threaded rod is threadedly connected to the inner wall of the L-shaped plate, a fixed round block is fixedly connected to one end of the threaded rod, and fixed round holes are provided on both sides of the frame.

[0013] The technical effect of adopting the above-mentioned further solution is that, under the action of the threaded rod, the fixed round block can be driven to move, which can then cooperate with the fixed round hole to provide auxiliary fixation and support for the adjustment frame and the frame body.

[0014] Compared with the prior art, the advantages and positive effects of this utility model are as follows:

[0015] By setting an adjustable limit structure, during the upward movement of the sliding block, the rectangular stop can block the limit plate, causing it to rotate. When it rotates to the appropriate position, the limit plate will reset. At this time, the sliding block will move upward a certain distance and be blocked by the rectangular stop, thus providing support. During this process, the sliding block only needs to move upward to complete the adjusted limit, without the need for manual fixation while maintaining the crane hoisting state. This makes the entire limiting and fixing process simple and convenient, and allows for adaptive height adjustment. By setting a disassembly and assembly limit structure, the adjustment frame can be disassembled and assembled under the action of the rectangular locking block and rectangular locking frame. At the same time, the adjustment frame can be auxiliaryly fixed and supported under the action of the fixing round block and fixing round hole. Attached Figure Description

[0024] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0025] like Figures 1-4 As shown, this embodiment provides a technical solution: an adaptive height-adjustable portal frame support device, including a base plate 1, with a frame 2 fixedly connected to the top of the base plate 1; adjustment limiting structures 3 are provided on the inner walls of both sides of the frame 2, the adjustment limiting structures 3 include sliding grooves 31 opened on both sides of the frame 2, auxiliary sliding grooves 32 are opened on the inner walls of both sides of the sliding grooves 31, two rows of rectangular blocks 33 are symmetrically fixedly connected to one side of the frame 2, and sliding blocks 34 are slidably arranged on the inner wall of the sliding grooves 31; a disassembly and assembly limiting structure 4 is provided on the top of the sliding blocks 34, the disassembly and assembly limiting structure 4 includes an adjusting frame 45, and a crossbeam 46 is fixedly connected to the top of the adjusting frame 45. By setting the adjustment limiting structure 3, the height can be adjusted during the upward movement of the sliding blocks 34. During the upward movement, the rectangular stop 33 can block the limiting plate 39, causing it to rotate. When it rotates to the appropriate position, the limiting plate 39 will reset. At this time, the sliding block 34 will be blocked by the rectangular stop 33 when it moves upward, thus providing support. During this process, the sliding block 34 only needs to move upward to complete the adjusted limit. There is no need to maintain the crane hoisting state for manual fixation, making the entire limiting and fixing process simple and convenient. The height can be adjusted adaptively. By setting the disassembly and assembly limiting structure 4, the adjusting frame 45 can be disassembled and assembled under the action of the rectangular card block 43 and the rectangular card frame 41. At the same time, the adjusting frame 45 can be assisted in fixing and supporting under the action of the fixing round block 49 and the fixing round hole 411.

[0026] Going a step further, such as Figure 2 and Figure 4As shown: Auxiliary sliders 35 are fixedly connected to both sides of the outer surface of the sliding block 34. The auxiliary sliders 35 are slidably disposed on the inner wall of the auxiliary groove 32. A U-shaped plate 36 is fixedly connected to the bottom of the outer surface of the sliding block 34. A rotating rod 37 is rotatably connected between the two sides of the inner wall of the U-shaped plate 36. A rotating block 38 is fixedly connected to the outer surface of the rotating rod 37. A limit plate 39 is fixedly connected to the outer surface of the rotating block 38. A torsion spring 310 is sleeved on the outer surface of the rotating rod 37. The two ends of the torsion spring 310 are fixedly connected to the outer surface of the U-shaped plate 36 and the outer surface of the rotating block 38, respectively. During rotation... Under the action of rod 37 and rotating block 38, the limiting plate 39 can be driven to rotate. In turn, it can cooperate with rectangular block 33 to block the limiting plate 39 when the sliding block 34 moves upward, causing the limiting plate 39 to rotate. Then, when the limiting plate 39 separates from the rectangular block 33 and the sliding block 34 moves to the upper position, the limiting plate 39 can be reset under the action of torsion spring 310. In turn, it can cooperate with rectangular block 33 to prevent it from rotating downward, thus providing auxiliary limiting for the sliding block 34 and limiting the sliding block 34.

[0027] The above solutions also have the problem that if the adjustment bracket 45 is bent and damaged, the entire unit needs to be replaced, increasing the cost of use. Figures 2-4 As shown: In this scheme, a rectangular frame 41 is fixedly connected to the top of the outer surface of the sliding block 34. A rectangular block 43 is snapped into the inner wall of the rectangular frame 41. The top of the rectangular block 43 is fixedly connected to the bottom of the adjusting frame 45. A first screw hole 42 is provided on one side of the rectangular frame 41. A second screw hole 44 is provided on the inner wall of the rectangular block 43. A threaded rod 410 is threadedly connected to the inner walls of the first screw hole 42 and the second screw hole 44. Under the action of the rectangular block 43 and the rectangular frame 41, the adjusting frame 45 and the sliding block 34 can be disassembled and assembled, and the adjusting frame 45 can be disassembled and replaced according to the actual use requirements.

[0028] The above solutions also have the problem that the adjusting bracket 45 is prone to bending under stress, and the rectangular stop block 33 is prone to breakage under large stress. Figures 2-4 As shown, an L-shaped plate 47 is fixedly connected to one side of the outer surface of the adjustment frame 45. A threaded rod 48 is threadedly connected to the inner wall of the L-shaped plate 47. A fixed round block 49 is fixedly connected to one end of the threaded rod 48. Fixed round holes 411 are provided on both sides of the frame 2. Under the action of the threaded rod 48, the fixed round block 49 can be driven to move, which can cooperate with the fixed round hole 411, thereby providing auxiliary fixation and support for the adjustment frame 45 and the frame 2.

[0029] Working principle:

[0030] like Figure 1-4 As shown:

[0031] In use: Use hoisting equipment or hydraulic telescopic equipment to lift the adjusting frame 45 upward. At this time, the sliding block 34 slides on the inner wall of the sliding groove 31, which can drive the auxiliary slider 35 to slide on the inner wall of the auxiliary sliding groove 32, which can drive the limit plate 39 to move.

[0032] When the limiting plate 39 abuts against the rectangular stop 33, it can drive the limiting plate 39 to rotate. When the sliding block 34 moves to the appropriate position, the limiting plate 39 can be reset under the action of the torsion spring 310, so that when the sliding block 34 moves downward, it can fit against the rectangular stop 33 and thus provide support.

[0033] At this time, rotate the threaded rod 48 so that the threaded rod 48 can drive the fixed round block 49 to fix with the fixed round hole 411;

[0034] When it is necessary to disassemble the adjustment bracket 45, the threaded clamp 410 is separated from the first screw hole 42 and the second screw hole 44, and the rectangular clamp 43 is separated from the rectangular clamp frame 41 to complete the disassembly.

[0035] The above description is merely a preferred embodiment of the present utility model and is not intended to limit the present utility model in any other way. Any person skilled in the art may make changes or modifications to the above-disclosed technical content to create equivalent embodiments for application in other fields. However, any simple modifications, equivalent changes, and modifications made to the above embodiments based on the technical essence of the present utility model without departing from the technical solution of the present utility model shall still fall within the protection scope of the technical solution of the present utility model.
