Description

Technical Field

[0001] This utility model relates to the field of support frame technology, specifically a support frame for mine roadways. Background Technology

[0002] Mine roadways are important passages and sites for mining operations. Due to complex and variable geological conditions, roadways are often in a state of high stress and are prone to dangerous situations such as collapses and roof falls. Support frames can effectively maintain the stability of roadways and prevent excessive deformation or damage by providing necessary support and fixation.

[0003] In existing technologies, U-shaped steel supports are used to support the interior of mine roadways to prevent dangerous situations such as collapses and roof falls. The U-shaped steel supports are mainly composed of U-shaped beams and columns set at both ends of the U-shaped beams.

[0004] The internal space of mine roadways is not entirely uniform in shape and size, and there are certain height differences. However, the U-shaped beams and columns of traditional U-shaped steel supports have fixed shapes, resulting in fixed assembly positions. They cannot be adapted and adjusted according to the height of the internal space of the mine roadway, which leads to some anchoring points on the U-shaped beams not being anchored in place. Utility Model Content

[0005] The purpose of this utility model is to provide a support frame for mine roadways, which effectively solves the problems mentioned in the background art.

[0006] To achieve the above objectives, the present invention provides the following technical solution.

[0007] A support frame for mine roadways includes a support frame body, which is composed of a U-shaped beam and a pair of support columns, with the two support columns respectively located at both ends of the U-shaped beam.

[0008] Preferably, both ends of the U-shaped beam have vertical portions; the support column includes a U-shaped steel column A and a U-shaped steel column B, the U-shaped steel column A is slidably assembled inside the U-shaped steel column B, and the top end of the U-shaped steel column A is fixedly connected to the vertical portion of the U-shaped beam.

[0009] Preferably, the U-shaped steel column A is provided with a vertically extending long groove, and the U-shaped steel column B is provided with a through insertion hole; the support column also includes a fastening bolt and a fastening nut, the fastening bolt passing through the long groove and the insertion hole in sequence and then being screwed and tightened with the fastening nut.

Therefore, they should not be construed as limitations on the embodiments of this utility model.

[0029] In this embodiment of the invention, the terms "first" and "second" are used for descriptive purposes only and should not be construed as indicating or implying relative importance or implicitly specifying the number of indicated technical features. Therefore, a feature defined with "first" and "second" may explicitly or implicitly include one or more of that feature.

[0030] Please see Figures 1-5This utility model provides a support frame for mine roadways, comprising a U-shaped beam 1 and a pair of support columns 2. The two support columns 2 are located at both ends of the U-shaped beam 1. The U-shaped beam 1 and the two support columns 2 together form the support frame body 01. Both ends of the U-shaped beam 1 have vertical parts 11. The support columns 2 are composed of U-shaped steel columns A21, U-shaped steel columns B22, fastening bolts 23, and fastening nuts 231. The U-shaped steel columns A21 are slidably assembled inside the U-shaped steel columns B22. The top of the U-shaped steel columns A21 is fixed to the vertical parts 11. The bottom of the U-shaped steel columns B22 is fixed with a base 24. The U-shaped steel columns A21 are provided with vertically extending long grooves 21. 1. The U-shaped steel column B22 is provided with a through insertion hole 221. The fastening bolt 23 passes through the long slot 211 and the insertion hole 221 in sequence, and is then tightened by screwing on the fastening nut 231. By loosening the fastening nut 231, the fastening bolt 23 can move relative to the long slot 211, thereby allowing relative sliding adjustment of the U-shaped steel column A21 and the U-shaped steel column B22 to achieve adjustment of the overall height of the support frame. After adjustment, tightening the fastening nut 231, in conjunction with the fastening bolt 23, can secure the U-shaped steel column A21 and the U-shaped steel column B22, which helps to maintain the overall stability and height.

[0031] Specifically, the U-shaped steel column A21 can be welded to the vertical part 11.

[0032] The support frame provided by this utility model is designed in a split manner, consisting of two parts: a U-shaped steel column A21 and a U-shaped steel column B22. The U-shaped steel column A21 is slidably embedded in the U-shaped steel column B22, which gives the U-shaped steel column A21 and the U-shaped steel column B22 the ability to slide and adjust relative to each other. This makes it easy to adjust the height of the support frame according to the actual height in the roadway, so that each anchor point on the U-shaped beam 1 can be anchored in place, thereby improving the support effect.

[0033] In addition, by setting both ends of the U-shaped beam 1 to be vertical, and after fixing it to the U-shaped steel column A21, the support column 2 can be kept vertical as a whole, thereby ensuring that the support column 2 is subjected to force in the vertical direction and that the support column 2 can provide effective support, resulting in a reasonable structural layout.

[0034] In addition, bases 24 are installed at the bottom of both U-shaped steel columns B22. Anchor holes are provided at the four corners of the bases 24. The bases 24 facilitate the fixing of the bottom of the U-shaped steel column B22 to the ground in the roadway, further improving the stability of the support frame.

[0035] like Figure 2 and Figure 4As shown, the support frame for this mine roadway also includes a connecting arm 3. Adjacent U-shaped beams 1 are reinforced and connected by the connecting arm 3. By arranging the support frame bodies 01 in an array along the extension direction of the mine roadway and reinforcing the adjacent U-shaped beams 1 with the connecting arm 3, a canopy can be formed. Arranging several support frame bodies 01 in an array in the roadway and reinforcing and connecting each U-shaped beam 1 with the connecting arm 3, a canopy is formed in the roadway, which can effectively improve the support effect.

[0036] like Figure 4 As shown, both ends of the connecting arm 3 are symmetrically fixed with mounting feet 31, and each mounting foot 31 is fitted with a fixing bolt 32. The mounting feet 31 are fastened to the U-shaped beam 1 by the fixing bolts 32. When two adjacent connecting arms 3 are reinforced, they abut each other end to end to tighten the fixing bolts 32 onto the U-shaped beam 1, thus achieving the fastening of the mounting feet 31 and the fixed connection between the connecting arm 3 and the U-shaped beam 1. At the same time, the abutting of the ends of two adjacent connecting arms 3 ensures the integrity of the reinforcement connection.

[0037] like Figure 3 and Figure 4 As shown, the connecting arm 3 has a wire groove 301 that runs through both ends, which facilitates the insertion and storage of cables. The side of the connecting arm 3 has an inlet and outlet 302 that extends along its length and communicates with the wire groove 301, which facilitates the entry and exit of cables.

[0038] The lower surface of the connecting arm 3 has at least two protrusions 303, and each protrusion 303 is provided with a fastening screw hole 304, which is used to fix the lamp holder of the lamp.

[0039] By setting a cable groove 301 inside the connecting arm 3 and setting an inlet and outlet 302 on the side, it is convenient to store and lay cables. The protrusion 303 and fastening screw hole 304 on the lower surface of the connecting arm 3 provide an installation position for the lighting lamp. At the same time, the connecting arm 3 also serves as a reinforcing connector between the support frames, achieving multiple benefits and strong functionality.

[0040] It will be apparent to those skilled in the art that this invention is not limited to the details of the exemplary embodiments described above, and that it can be implemented in other specific forms without departing from the spirit or essential characteristics of this invention. Therefore, the embodiments should be considered illustrative and non-limiting in all respects, and the scope of this invention is defined by the appended claims rather than the foregoing description. Thus, it is intended that all variations falling within the meaning and scope of equivalents of the claims be included within this invention. No reference numerals in the claims should be construed as limiting the scope of the claims.
