Description

Technical Field

[0001] This application relates to the field of H-shaped steel column transportation technology, and specifically discloses an H-shaped steel column clamping structure. Background Technology

[0002] H-shaped steel columns are an economical and efficient profile with a more optimized cross-sectional area distribution and a more reasonable strength-to-weight ratio. They are named for their cross-section resembling the letter "H". Because all parts of an H-shaped steel column are arranged at right angles, it possesses advantages such as strong bending resistance in all directions, simple construction, cost savings, and lightweight structure, and has been widely used.

[0003] After the H-beams are welded and formed, they need to undergo end face grinding and warehousing. Currently, during the transportation of H-beams, ropes are mostly used to secure them to the vehicle body. Rope securing is not only cumbersome, time-consuming, and labor-intensive, but also increases the risk of the H-beams tilting or falling over during transportation, potentially leading to cracks or even breakage.

[0004] Some transport vehicles are equipped with clamps to hold H-shaped steel columns in place. While this provides a more effective fixation, the overall structure is bulky and the clamping process is complex, resulting in a long time required to secure the H-shaped steel columns. In view of this, this utility model provides an H-shaped steel column clamping structure to solve the above problems. Utility Model Content

[0005] The purpose of this utility model is to solve the problem that the traditional method of fixing H-shaped steel columns with ropes is cumbersome, time-consuming and labor-intensive during transportation.

[0006] To achieve the above objectives, the basic solution of this utility model provides an H-shaped steel column clamping structure, including a connecting seat and support platforms symmetrically arranged on both sides of the connecting seat. A first sliding cavity is provided on the upper surface of the support platform. The sliding cavity is vertically slidably connected to a slide seat that can accommodate the H-shaped steel column. Side plates are provided on the opposite sides of the support platform. The side plates are provided with a second sliding cavity that communicates with the first sliding cavity. A pressure plate that can fit against the side of the H-shaped steel column is horizontally slidably connected to the second sliding cavity. A bottom wedge is provided at the bottom of the pressure plate, located in the first sliding cavity. Several return springs are provided between the end of the bottom wedge and the side wall of the first sliding cavity. A top wedge is provided at the bottom of the slide seat that matches the bottom wedge.

[0007] The principle and effect of this basic scheme are as follows:

[0008] Compared with existing technologies, this utility model supports the H-shaped steel column by setting a sliding block, and the weight of the H-shaped steel column presses the sliding block downward. The mating surfaces of the top and bottom wedges drive the pressure plate to move, so that the pressure plate presses the H-shaped steel column tightly, thereby achieving the purpose of limiting and clamping the side of the H-shaped steel column. In this way, it clamps the H-shaped steel column with a smaller structure and portability, effectively solving the problem of cumbersome, time-consuming and labor-intensive operation of fixing with ropes during the transportation of traditional H-shaped steel columns.

[0009] Furthermore, several connecting posts are provided between the bottom of the slide block and the top wedge block. This facilitates the connection between the slide block and the top wedge block, and allows for the replacement of connecting posts of different lengths to meet the clamping requirements of H-beam columns of different models and specifications.

[0010] Furthermore, the second sliding cavity is located inside the side plate. Each side plate has several through holes on its adjacent sides. The pressure plate has several pressure columns near its sidewall that can pass through these through holes and fit against the surface of the H-shaped steel column. This method, by using multiple points to clamp the side of the H-shaped steel column, improves the limiting and clamping effect on the side of the H-shaped steel column, preventing relative slippage between the H-shaped steel column and the pressure plate.

[0011] Furthermore, the second sliding cavity is provided with several sleeves corresponding to the positions of the through holes, and the pressure column is slidably connected to the sleeves. This further positions the pressure column, not only preventing it from disengaging from the through holes, but also limiting and guiding its sliding.

[0012] Furthermore, a partition is provided inside the first sliding cavity, and the slide block is slidably connected between the partition and the inner wall of the first sliding cavity. The partition and the bottom of the first sliding cavity form a through groove. The pressure plate is L-shaped, with its vertical section slidably connected to the second sliding cavity horizontally, and its horizontal section slidably connected to the through groove. The partition can simultaneously limit and guide the sliding of both the slide block and the pressure plate.

[0013] Furthermore, the surface of the slide block is uniformly provided with several pads. The pads can improve the contact effect between the H-shaped steel column and the slide block, and prevent relative slippage between the H-shaped steel column and the slide block.

[0014] Furthermore, a reinforcing plate is provided between the top of the side plate and the end of the connecting seat. The reinforcing plate can improve the stability of the side plate. Attached Figure Description

[0018] To further illustrate the technical means and effects adopted by this utility model in order to achieve the intended utility model purpose, the following detailed description of the specific implementation methods, structure, features and effects of this utility model is provided in conjunction with the accompanying drawings and preferred embodiments.

[0019] The reference numerals in the accompanying drawings include: H-shaped steel column 1, connecting seat 2, support platform 3, pad block 4, side plate 5, reinforcing plate 6, slide block 7, connecting column 8, top wedge block 9, bottom wedge block 10, pressure plate 11, pressure column 12, sleeve 13, partition plate 14, and return spring 15.

[0020] An H-shaped steel column clamping structure, implemented as follows: Figure 1 and Figure 2 As shown: It includes a connecting seat 2, support platforms 3 symmetrically arranged on both sides of the connecting seat 2, side plates 5 respectively arranged on the opposite side of the support platform 3, and reinforcing rods respectively arranged between the top of the side plate 5 and the end of the connecting seat 2.

[0021] The connecting seat 2 is fixed to the vehicle body carrying the H-shaped steel column 1 by bolts. The upper surface of the support platform 3 is provided with a first sliding cavity, which is vertically slidably connected to a sliding seat 7 that can accommodate the H-shaped steel column 1. The side plate 5 is provided with a second sliding cavity that communicates with the first sliding cavity. The second sliding cavity is horizontally slidably connected to a pressure plate 11. Each side of the side plate 5 is provided with several through holes. The pressure plate 11 is provided with several pressure columns 12 near the side wall that can pass through the through holes and fit against the surface of the H-shaped steel column 1. The second sliding cavity is provided with several sleeves 13 corresponding to the positions of the through holes. The pressure columns 12 are slidably connected to the sleeves 13. The sleeves 13 can position the pressure columns 12, which can not only prevent the pressure columns 12 from separating from the through holes, but also limit and guide the sliding of the pressure columns 12.

[0022] A vertical partition 14 is provided inside the first sliding cavity. The two sides of the slide block 7 are respectively attached to the partition 14 and the inner wall of the first sliding cavity. Several pads 4 are evenly distributed on the surface of the slide block 7. A top wedge 9 is provided at the bottom of the slide block 7 through multiple connecting posts 8. The partition 14 and the bottom of the first sliding cavity form a through groove. The pressure plate 11 is L-shaped. The vertical section of the pressure plate 11 is horizontally slidably connected to the second sliding cavity. The horizontal section of the pressure plate 11 is slidably connected to the through groove. The horizontal section of the pressure plate 11 extends into the bottom of the top wedge 9 and is provided with a bottom wedge 10 that matches the top wedge 9. Several return springs 15 are provided between the end of the bottom wedge 10 and the side wall of the first sliding cavity. The side of the partition 14 cooperates with the side wall of the first sliding cavity to guide the movement of the slide block 7. The bottom of the partition 14 cooperates with the bottom of the first sliding cavity to guide the sliding of the pressure plate 11.

[0023] After the H-beam column 1 is placed on each pad 4, the weight of the H-beam column 1 presses down on the slide block 7. The mating surfaces of the top wedge block 9 and the bottom wedge block 10 drive the pressure plate 11 to move, so that the pressure plate 11 presses the H-beam column 1 tightly, thereby achieving the purpose of limiting and clamping the side of the H-beam column 1. During this process, the pressure column 12 presses against the side of the H-beam column 1, which can improve the limiting and clamping effect on the side of the H-beam column 1 and prevent relative slippage between the H-beam column 1 and the pressure plate 11. The pad 4 can improve the contact effect between the H-beam column 1 and the slide block 7 and prevent relative slippage between the H-beam column 1 and the slide block 7. When unloading the H-beam column 1, the H-beam column 1 is lifted upward by a jack or hydraulic lifting device, which can release the restriction of the pressure plate 11 on the H-beam column 1. At the same time, the return spring 15 drives the slide block 7 and the pressure plate 11 to return to their original positions.

[0024] Compared with the prior art, this embodiment can clamp the H-shaped steel column 1 with a smaller structure and portability, effectively solving the problem of cumbersome, time-consuming and labor-intensive operation of fixing with ropes during the transportation of traditional H-shaped steel columns 1.

[0025] 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 way. Although the present utility model has been disclosed above with reference to a preferred embodiment, it is not intended to limit the present utility model. Any person skilled in the art can make some modifications or alterations to the above-disclosed technical content to create equivalent embodiments without departing from the scope of the present utility model. Any indirect modifications, equivalent changes, and alterations made to the above embodiments based on the technical essence of the present utility model without departing from the scope of the present utility model shall still fall within the scope of the present utility model.
