DETAILED DESCRIPTION

[0028] In order to make the technical problems, technical solutions and beneficial effects to be solved by the present invention more clearly understood, the present invention is further described in detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are only used to explain the present invention and are not intended to limit the present invention.

[0029] like Figure 1-7 As shown, a fixing device for a single-slit telescopic assembly includes a support member and a limiting assembly. Two sets of limiting assemblies are arranged at intervals along the long side direction of the support member and are both located on the top of the support member. A bolt assembly 5 is used between the two sets of limiting assemblies to limit the position of multiple single-slit telescopic assemblies 1.

[0030] The single-slit telescopic assembly 1 includes a steel section 101 and a stainless steel belt 102 . The two steel sections 101 are respectively arranged on both sides of the long side of the stainless steel belt 102 . The steel sections 101 are fastened to the limiting assembly via the bolt assembly 5 .

[0031] Example 1

[0032] like Figure 1-5 As shown, specifically, the support member is an I-beam 2 7, and the limiting assembly includes an I-beam 2, an angle steel 3, a reinforcing round steel 4 and a wire rope clamp 6. The four corners of the I-beam 2 are welded with an angle steel 3, and multiple I-beams 2 are overlapped together in the vertical direction through the angle steel 3, and the I-beam 2 at the bottom is welded to the top of the I-beam 2 7.

[0033] Specifically, the spacing between the two I-beams 2 arranged on the top of the I-beam 2 7 is determined according to the seam width required for delivery of the single-slit telescopic assembly 1, which plays a role in lateral constraint on the single-slit telescopic assembly.

[0034] The two sets of limit assemblies are provided with openings on the opposite walls of the I-beam 102, and the bolt assembly 5 passes through the openings and is locked and connected with the section steel 101;

[0035] A through hole 1 is provided in the middle of the I-beam 1 2 at the top, and a through hole 2 is provided on both sides of the top of the I-beam 2 7. The two through holes 2 are respectively hung with a wire rope clamp 6, and hooks are respectively provided at both ends of the reinforcing round steel 4. After the reinforcing round steel 4 passes through the through hole 1, it is hung together with the two wire rope clamps 6.

[0036] Specifically, one side wall of each I-beam 2 is provided with two openings.

[0037] Specifically, a dovetail groove is formed on the side of the steel section 101 away from the stainless steel strip 102;

[0038] The bolt assembly 5 includes a bolt body 501 and a trapezoidal nut 502. The trapezoidal nut 502 is nested in the dovetail groove. The bolt body 501 passes through the I-beam 2 and is threadedly fastened to the trapezoidal nut 502.

[0039] The usage process of this embodiment is as follows:

[0040] First, place the horizontal I-beam 2 as a base, and weld two I-beams 1 to the top of the I-beam 2. The spacing between them is determined according to the seam width required for the single-slit telescopic assembly, which serves as a lateral constraint for the single-slit telescopic assembly.

[0041] Then, four sections of angle steel 3 are welded and fixed to the four corners of the I-section of the I-beam. The sides of the I-beams 2 facing each other in the two sets of limiting assemblies are provided with openings for installing bolt bodies 501. The bolt bodies 501 penetrate the I-beam 2 and are threadedly fastened together with the trapezoidal nuts 502 nested in the dovetail grooves of the section steel 101, thereby achieving locking and limiting of the single-slit telescopic assembly. Multiple I-beams 2 in each set of limiting assemblies are overlapped, and the angle steel 3 limits the multiple I-beams 2, making it easy to stack multiple I-beams 2 together.

[0042] Finally, use the reinforcing round steel 4 and the wire rope clamp 6 to firmly fix the stacked I-beams 2.

[0043] Example 2

[0044] like Figure 6-7 As shown, the support member is a channel steel 2 8, and the limiting assembly includes an angle steel 2 9 and a pressure plate 10. Two angle steels 29 are welded to the top of the channel steel 2 8 in the vertical direction. An opening is provided on the wall of the angle steel 2 9. The bolt assembly 5 passes through the opening and is locked with the steel section 101 of the single-slit telescopic assembly 1. The top of the angle steel 2 9 passes through the pressure plate 10 and is clamped together.

[0045] Specifically, the spacing between the two angle steels 9 provided on the top of the support member is determined according to the seam width required for delivery of the single-slit telescopic assembly, and serves to laterally constrain the single-slit telescopic assembly.

[0046] A limiting protrusion 11 for clamping and connecting with the pressing plate 10 is provided on the top of the angle steel 9.

[0047] The angle steel 2 9 is provided with a plurality of openings in the vertical direction for installing the bolt assembly 5 , and the bolt assembly 5 is used to limit the positions of the multiple rows of single-slit telescopic assemblies 1 .

[0048] Specifically, the fixing device uses channel steel as the support member, and there is a gap at the bottom of the channel steel to facilitate overall lifting; the support member can also be a bottom plate. If the bottom plate is used as the support member, the bottom support is more stable and the cost is lower.

[0049] Specifically, the pressing plate 10 protects the upper exposed surface of the single-slit telescopic assembly from being damaged.

[0050] Specifically, the support member can also be a steel plate, square steel, H-shaped steel, etc. The angle steel frame can also be replaced by a steel plate, T-shaped steel, etc. The bolts can be arranged in a single row, double row, or multiple rows.

[0051] The usage process of this embodiment is as follows:

[0052] First, two angle steels 29 are vertically clamped and fixed on top of the buckled channel steel 28. The spacing between the two angle steels 29 is determined according to the seam width required for delivery of the single-slit telescopic assembly, and plays a role in lateral restraint of the single-slit telescopic assembly. The channel steel 28 can be replaced by a bottom plate.

[0053] Then, the opposite surfaces of the two opposing angle steels 9 are provided with openings for installing the bolt assembly 5, which is used to limit the position of the single-slit telescopic assembly;

[0054] Finally, the pressing plate 10 is used to be fixed on the upper portion of the angle steel 2 9 and to protect the upper exposed surface of the single-slit telescopic assembly from being damaged.
