Description

[Technical field]

[0001] The utility model belongs to the technical field of underground single-body support, and in particular relates to a column-beam interlocking mechanism with a single-body anti-collapse function. [Background technology]

[0002] The underground single support independent hydraulic support device plays a supporting role in the underground tunnel. Since the single body itself has no linking anti-falling device, the single body and the beam cannot be fixedly connected, but moved forward or re-supported as needed. However, if the single body and the beam are not fixed, there will be a risk of the single body falling, so the column-beam interlocking is required. Usually, the underground single support uses nylon networking ropes for column-beam interlocking, but the connection strength of nylon networking ropes is low, and it is easy to break after being squeezed. The construction is complicated and wastes materials. [Contents of the utility model]

[0003] The utility model aims to provide a column-beam interlocking mechanism with a single body anti-falling function, so as to solve the problems of low strength and complex construction of the existing column-beam interlocking mechanism.

[0004] The utility model adopts the following technical scheme: a column-beam interlocking mechanism with a single-body anti-falling function, comprising a vertically arranged single body, a crossbeam vertically arranged above the single body; the crossbeam comprises an upper side plate and a lower side plate, and a plurality of slots are arranged on both sides of the upper side plate and the lower side plate; the single body comprises a telescopic section located at the lower part and a fixed section located at the upper part, a top plate is arranged at the upper part of the fixed section, and four column claws are evenly distributed above the top plate; the column claws are used to be clamped in different slots, so that the single body and the crossbeam can be clamped at different positions;

[0005] A clamp is installed on the outer wall of the fixed section of the monomer;

[0006] One end of a chain is fixedly connected to the clamp, and the other end of the chain is connected to an S hook. The chain is used to pass through the monomer, go around the beam upward, and then return to the vicinity of the clamp; the S hook is used to connect the two ends of the chain.

[0007] Furthermore, the minimum size of the clamp is equal to the column diameter of the fixed section of the monomer.

[0008] Furthermore, the width of the crossbeam is 100 mm, the circumference of the crossbeam is 400 mm, and the length of the chain is 500 mm.

[0009] The beneficial effects of the utility model are as follows: a clamp is arranged at a fixed section at the top of the single body, the clamp is connected to a chain, the chain is wound around the crossbeam and then returns to the vicinity of the single body and is locked by an S hook. The structure is simple to process and easy to use, and it solves the problem of material waste, saves construction time, and increases the safety factor. When the single body is moved forward or re-supported, it does not affect the lifting and lowering of the single body, and disassembly and assembly are avoided.

[0015] The utility model is described in detail below with reference to the accompanying drawings and specific implementation modes.

[0016] The utility model provides a column-beam interlocking mechanism with a single body anti-falling function, such as Figure 1 As shown, it includes a vertically arranged monomer 1, and a crossbeam 2 is vertically arranged above the monomer 1; the crossbeam 2 includes an upper side plate 202 and a lower side plate 203, as shown in FIG. Figure 3 As shown, a plurality of slots 201 are provided on both sides of the upper side plate 202 and the lower side plate 203; Figure 2-1 and Figure 2-2 As shown, the monomer 1 includes a telescopic section 101 located at the bottom and a fixed section 102 located at the top, a top plate 103 is provided on the top of the fixed section 102, and four column claws 104 are evenly distributed above the top plate 103; the column claws 104 are used to be clamped in different clamping slots 102, so that the monomer 1 and the crossbeam 2 can be clamped at different positions;

[0017] A clamp 3 is installed on the outer wall of the fixed section 102 of the single body 1; one end of a chain 4 is fixedly connected to the clamp 3, and the other end of the chain 4 is connected to an S hook 5, and the chain 4 is used to pass through the single body 1, bypass the beam 2 upward, and then return to the vicinity of the clamp 3; the S hook 5 is used to connect the two ends of the chain 4 to realize the column-beam interlocking of the single body support.

[0018] In some embodiments, the minimum size of the clamp 4 is equal to the column diameter of the fixing section 102 of the monomer 1 to ensure the fit between the clamp and the monomer.

[0019] In some embodiments, based on the width of the beam 2 of 100 mm and the circumference of the beam 2 of 400 mm, the length of the chain 5 is determined to be 500 mm. The length of the chain should not be too long, otherwise the column-beam interlocking anti-collapse function will not be achieved.

[0020] The method of using the column-beam interlocking mechanism with the single body anti-falling function of the utility model is as follows: the chain 4 connected to the clamp 3 at the top of the single body 1 is placed backward under the cross beam 2, then bypassed from above the cross beam 2, and finally returned to the vicinity of the single body 1, and the S hook 5 is hung and locked in the eye of the chain 4, thus completing the detachable connection of the column and beam. If the single body needs to be moved forward or re-supported, the S buckle is unfastened, the chain is removed, and the single body can be moved.
