Description

Technical Field

[0001] This utility model relates to the field of steel structure storage technology, and in particular to a temporary steel structure support frame with adjustable height. Background Technology

[0002] Steel structures are structures made primarily of steel. They have advantages such as high strength, light weight, good seismic performance, short construction period, and recyclability, and are widely used in industrial and civil buildings, bridges, towers, masts, containers, and other fields.

[0003] In existing technologies, after steel structures are transported to the location where they need to be assembled, the unassembled steel structures need to be temporarily stacked. However, the lack of stable support and protection for the steel structures before assembly can affect the stability of the storage and pose significant safety hazards. Furthermore, conventional support frames are difficult to adjust their height according to usage requirements, making it difficult to meet the needs of use. Utility Model Content

[0004] The purpose of this utility model is to solve the problem that in the prior art, after steel structures are transported to the location where they need to be assembled, they need to be temporarily stacked before installation. However, the steel structures lack stable support and protection when they are not assembled, which affects the stability of the steel structures during storage and poses a significant safety hazard. Conventional support frames are difficult to adjust their height according to usage requirements and cannot meet the usage needs. Therefore, this utility model proposes an adjustable height temporary support frame for steel structures.

[0005] To achieve the above objectives, the present invention adopts the following technical solution:

[0006] An adjustable-height temporary steel structure support frame includes a first support plate and a second support plate. The first support plate is concave, and the second support plate is convex. The second support plate is slidably disposed in the concave part of the first support plate. Two support frames are fixedly connected to the side wall of the first support plate. A fixing plate is fixedly connected to the inner wall of the bottom end of the first support plate. A strip-shaped opening is formed in the inner wall of the fixing plate. A lead screw is rotatably connected to the inner wall of the strip-shaped opening on the fixing plate. A slider is threaded onto the wall of the lead screw. The slider is fixedly connected to the side wall of the second support plate. A connecting platform is fixedly connected to the top of the fixing plate. A motor is fixedly connected to the top of the connecting platform. The output shaft of the motor is fixedly connected to the top of the lead screw.

[0007] Preferably, the bottom inner wall of the support frame is provided with mounting holes.

[0008] Preferably, the support frame is configured as an L-shaped plate, and a reinforcing plate is fixedly connected to the inner wall of the support frame, the reinforcing plate being inclined.

[0009] Preferably, multiple anti-slip rubber strips are fixedly connected to the side walls of the first support plate and the second support plate, respectively.

[0010] Preferably, a guide slide is fixedly connected to the bottom of the second support plate, and a guide groove is provided on the inner wall of the bottom end of the first support plate, and the guide slide is slidably disposed on the inner wall of the guide groove.

[0011] Preferably, the guide slide plate has a strip-shaped opening on its side wall, and the guide slide plate is rotatably connected to multiple rollers located on the inner wall of the strip-shaped opening. The rollers are rolled on the inner wall of the guide groove.

[0012] Compared with the prior art, this utility model provides an adjustable-height temporary steel structure support frame, which has the following advantages:

[0013] 1. This height-adjustable temporary steel structure support frame uses the output shaft of a motor to drive a lead screw to rotate within a slot in the inner wall of a fixed plate. Since the lead screw is threadedly connected to a slider, and the slider is fixedly connected to the side wall of the second support plate, according to the principle of threaded transmission, when the lead screw rotates, the slider will move axially along the wall of the lead screw. The second support plate is convex and slidably disposed in the recess of the first support plate. The movement of the slider will cause the second support plate to slide smoothly up and down within the first support plate, thereby realizing the adjustment of the overall height of the support frame.

[0014] 2. This height-adjustable steel temporary support frame uses two L-shaped support frames for support and fixation. The mounting holes on the inner wall of the bottom can be used to fix the support frame to the ground or other support surface through bolts and other connectors to enhance stability. The inclined reinforcing plates on the inner wall of the support frame can enhance the structural strength of the support frame, distribute the force, improve its load-bearing capacity, and prevent the support frame from deforming under stress.

[0015] 3. The height-adjustable steel temporary support frame slides within the guide groove on the inner wall of the bottom of the first support plate via the guide slide plate at the bottom of the second support plate. The rollers in the strip-shaped opening on the side wall of the guide slide plate roll into contact with the inner wall of the guide groove, reducing sliding friction. Attached Figure Description

[0020] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments.

[0021] Reference Figure 1-3 An adjustable-height temporary steel structure support frame includes a first support plate 1 and a second support plate 2. The first support plate 1 is concave, and the second support plate 2 is convex. The second support plate 2 is slidably disposed in the concave part of the first support plate 1. Two support frames 3 are fixedly connected to the side wall of the first support plate 1. A fixing plate 4 is fixedly connected to the inner wall of the bottom end of the first support plate 1. A strip-shaped opening is opened on the inner wall of the fixing plate 4. A lead screw 7 is rotatably connected to the inner wall of the strip-shaped opening of the fixing plate 4. A slider 8 is threadedly connected to the wall of the lead screw 7. The slider 8 is fixedly connected to the side wall of the second support plate 2. A connecting platform 5 is fixedly connected to the top of the fixing plate 4. A motor 6 is fixedly connected to the top of the connecting platform 5. The output shaft of the motor 6 is fixedly connected to the top of the lead screw 7.

[0022] The bottom inner wall of the support frame 3 has an installation hole 9. The support frame 3 is set as an L-shaped plate. A reinforcing plate 10 is fixedly connected to the inner wall of the support frame 3. The reinforcing plate 10 is inclined. Multiple anti-slip rubber strips 11 are fixedly connected to the side walls of the first support plate 1 and the second support plate 2 respectively.

[0023] When the height of the support frame needs to be adjusted, the motor 6 at the top of the connecting platform 5 is started. The output shaft of the motor 6 drives the lead screw 7 to rotate in the slotted opening on the inner wall of the fixed plate 4. Since the lead screw 7 is threadedly connected to the slider 8, and the slider 8 is fixedly connected to the side wall of the second support plate 2, according to the principle of thread transmission, when the lead screw 7 rotates, the slider 8 will move axially on the rod wall of the lead screw 7. The second support plate 2 is set in a convex shape and is slidably set in the recess of the first support plate 1. The movement of the slider 8 will drive the second support plate 2 to slide smoothly up and down in the first support plate 1, thereby realizing the adjustment of the overall height of the support frame.

[0024] During the operation of the support frame, the two L-shaped support frames 3 play a supporting and fixing role. The mounting holes 9 on the inner wall of the bottom end can be used to fix the support frame to the ground or other supporting surface through bolts and other connecting parts to enhance stability. The reinforcing plate 10 inclined on the inner wall of the support frame 3 can enhance the structural strength of the support frame 3, distribute the force, improve its load-bearing capacity, and prevent the support frame 3 from deforming when under force.

[0025] Multiple anti-slip rubber strips 11 on the side walls of the first support plate 1 and the second support plate 2 increase the friction between the support and the object being supported, preventing the object from sliding on the support frame and ensuring the safety and stability of the support.

[0026] To reduce sliding friction, such as Figure 1-3 As shown, a guide slide plate 12 is fixedly connected to the bottom of the second support plate 2. A guide groove is provided on the inner wall of the bottom end of the first support plate 1. The guide slide plate 12 is slidably disposed on the inner wall of the guide groove. A strip-shaped opening is provided on the side wall of the guide slide plate 12. Multiple rollers 13 are rotatably connected to the inner wall of the strip-shaped opening of the guide slide plate 12. The rollers 13 are rotatably disposed on the inner wall of the guide groove.

[0027] The guide slide plate 12 at the bottom of the second support plate 2 slides in the guide groove on the inner wall of the bottom end of the first support plate 1. The roller 13 in the strip-shaped opening on the side wall of the guide slide plate 12 rolls and contacts the inner wall of the guide groove, reducing the sliding friction.

[0028] The above description is only a preferred embodiment of the present utility model, but the protection scope of the present utility model is not limited thereto. Any equivalent substitutions or changes made by those skilled in the art within the technical scope disclosed in the present utility model, based on the technical solution and the inventive concept of the present utility model, should be included within the protection scope of the present utility model.
