[0026] The embodiments of the present invention are described in detail below, and examples of the embodiments are shown in the accompanying drawings. The embodiments described below with reference to the accompanying drawings are exemplary and intended to be used to explain the present invention, but cannot be understood as limiting the present invention.
[0027] The retreat slideway of the fully mechanized caving working face in the embodiment of the utility model comprises a plurality of U-shaped beams 1, two rails 2 and two deflection-blocking beams 3.
[0028] A plurality of U-shaped beams 1 are arranged at intervals, for example Figure 1 As shown, the U-shaped beam 1 is U-shaped as a whole, and there can be three U-shaped beams 1 in total, and the three U-shaped beams 1 can be arranged in parallel and spaced in the front-to-back direction. In some other embodiments, the U-shaped beams 1 can also be provided in four, five, six or other quantities.
[0029] Each U-shaped beam 1 includes a cross beam section 11, a first vertical beam section 12, and a second vertical beam section 13. The first vertical beam section 12 is arranged at one end of the cross beam section 11, and the second vertical beam section 13 is arranged at the other end of the cross beam section 11. Figure 1 As shown, the cross beam section 11 can extend in the left-right direction, the first vertical beam section 12 can be welded and fixed at the left end of the cross beam section 11 and extend upward, and the second vertical beam section 13 can be welded and fixed at the right end of the cross beam section 11 and extend upward.
[0030] like Figure 1 As shown, both rails 2 extend in the front-to-back direction, and both rails 2 are connected to the cross beam sections 11 of the multiple U-shaped beams 1 and are arranged at intervals in the extending direction of the cross beam sections 11. Specifically, both rails 2 can be fixed to the multiple cross beam sections 11 by bolts or other fasteners, and the two rails 2 can be arranged in parallel and at intervals in the left-right direction. When in use, the top surfaces of the two rails 2 can be supported on the bottom side of the working surface equipment such as the hydraulic support, and the working surface equipment can slide along the rails 2, thereby facilitating the withdrawal of the working surface equipment.
[0031] like Figure 1 As shown, multiple first vertical beam sections 12 can be arranged on the left side of the corresponding horizontal beam section 11, and multiple second vertical beam sections 13 can be arranged on the right side of the corresponding horizontal beam section 11. One deflection blocking beam 3 is connected to multiple first vertical beam sections 12, and another deflection blocking beam 3 is connected to multiple second vertical beam sections 13. In this way, the retraction slideway can be made into a groove-like structure as a whole. When the working surface equipment slides on the track 2, it can stop and limit the working surface equipment, thereby avoiding the situation where the working surface equipment laterally escapes from the retraction slideway, and ensuring the stability of use.
[0032] It should be noted that the connection between the U-shaped beam 1 and the deflection beam 3 of the retracting slideway of the embodiment of the utility model, and the connection between the crossbeam section 11 and the track 2 can be detachably installed and fixed by fasteners such as bolts, thereby facilitating transportation and on-site installation.
[0033] The disassembly and assembly of the retreat slideway of the comprehensive caving working face in the embodiment of the utility model is quick and convenient, and the stability is good. It can reduce the friction between the working face equipment such as the hydraulic support and the bottom plate, avoid the situation of digging the bottom, and improve the convenience of transporting the working face equipment.
[0034] In some embodiments, a plurality of first grooves 31 are provided on the deflection blocking beam 3 , and the first vertical beam section 12 or the second vertical beam section 13 is embedded and fixed in the corresponding first groove 31 of the deflection blocking beam 3 .
[0035] For example, Figure 1 and Figure 2 As shown, the number of first grooves 31 on the deflection beam 3 can be the same as the number of U-shaped beams 1, thereby, multiple first vertical beam sections 12 can be embedded in multiple first grooves 31 one by one, and the structural stability of the assembly of the deflection beam 3 and the U-shaped beam 1 can be enhanced by the stopping and limiting of the groove wall of the first groove 31.
[0036] In some embodiments, the deflection blocking beam 3 is disposed on the inner side of the first vertical beam section 12 or the second vertical beam section 13, and the plurality of first grooves 31 are disposed on the outer side of the deflection blocking beam 3. Figure 1 As shown, the two deflection-blocking beams 3 are both substantially located between the first vertical beam section 12 and the second vertical beam section 13. Thus, the deflection-blocking beam 3 can utilize the space between the first vertical beam section 12 and the second vertical beam section 13, so that avoidance can be formed between the two adjacent vertical beam sections, thereby reducing the situation where external components directly act on the deflection-blocking beam 3.
[0037] In some embodiments, the cross beam section 11 is provided with a second groove 111, and the bottom of the track 2 is embedded in the second groove 111. Figure 1 and Figure 3 As shown, the second groove 111 can be arranged at the top of the beam section 11, and the notch of the second groove 111 can be upward. When installing the rail 2, the rail 2 can be embedded in the second groove 111 of the beam section 11. By means of the blocking and limiting function of the groove wall of the second groove 111, the structural stability of the assembly of the rail 2 and the beam section 11 can be enhanced.
[0038] In some embodiments, the rail 2 is an I-beam, the second groove 111 is a T-slot, and a wing plate of the rail 2 fits into the T-slot. It should be noted that the I-beam includes a web and two wing plates, the two wing plates are arranged in parallel and spaced apart, and the web plate is connected between the two wing plates. During installation, a wing plate and part of the web plate of the rail 2 can be passed through the T-slot, thereby achieving position restriction of the rail 2 in the up and down directions, avoiding the rail 2 from falling out of the notch of the second groove 111, and further enhancing the stability and structural strength of the assembly.
[0039] In some embodiments, Figure 1As shown, the cross beam section 11, the first vertical beam section 12, the second vertical beam section 13, the track 2, and the deflection-blocking beam 3 are all I-beams. Thus, while ensuring the structural strength, it is also convenient to obtain materials on site.
[0040] In some embodiments, Figure 1 As shown, the webs of the first vertical beam section 12, the second vertical beam section 13, the track 2, and the deflection beam 3 are arranged vertically, and the web of the cross beam section 11 is arranged horizontally. As a result, the load-bearing direction of the webs of each beam is roughly consistent with the main load-bearing direction in actual use, thereby meeting the use needs of higher load-bearing.
[0041] In some embodiments, a reinforcing plate is provided at the connection between the cross beam section 11 and the first vertical beam section 12, and at the connection between the cross beam section 11 and the second vertical beam section 13. Figure 1 As shown, the reinforcing plate can be a triangular plate, which can be welded and fixed at the corner connection formed by the cross beam section 11 and the corresponding vertical beam section (the first vertical beam section 12 or the second vertical beam section 13). Each connection can be provided with two reinforcing plates, and the two reinforcing plates can be respectively arranged on the front and rear sides of the connection, thereby further improving the structural strength of the connection and ensuring the load-bearing use needs.
[0042] In some embodiments, the length of the cross beam section 11 in the left-right direction is 1.85m, the height of the first vertical beam section 12 and the second vertical beam section 13 are both 0.4m, the spacing between the two rails 2 in the left-right direction is 0.9m, and the length of the rails 2 and the deflection beam 3 in the front-back direction can both be 4m. Thus, the corresponding dimensions of the retraction slide can be adapted to the corresponding dimensions of the existing working surface equipment.
[0043] The retraction slides of the embodiments of the utility model are all mechanically connected, and are quick and convenient to disassemble and assemble. The positioning is enhanced by grooves, etc., and the overall stability is good. Secondly, it is safe and efficient to use, and can also reduce the left and right shaking of the bracket during use, and also play a role in reducing the friction between the bracket and the bottom plate, solving many unsafe factors caused by shoveling and transportation, optimizing the working environment, and can be reused. The retraction slides are all made of waste recycled materials, which are simple to process and manufacture, safe and efficient to retract, and have good on-site practicality. They can be widely promoted and applied in the process of winch retraction of brackets under complex conditions.
[0044] Although the above embodiments have been shown and described, it is to be understood that the above embodiments are illustrative and cannot be construed as limitations on the present invention. Changes, modifications, substitutions and variations of the above embodiments by those of ordinary skill in the art are all within the scope of protection of the present invention.
