Abstract
Description
Technical Field
[0001] This utility model relates to the technical field of roadway support devices, specifically to an inclined support unit bracket. Background Technology
[0002] my country's coal mines are primarily underground, requiring the excavation of numerous roadways. Roadway support is crucial for maintaining roadway access and surrounding rock stability, which is essential for coal mine construction and production. To improve support stability, multiple roadway support units are typically used within the roadway. Ideally, the roadway roof is almost flat, allowing for direct support and protection using traditional hydraulic cylinders paired with horizontal roof beams. However, due to the instability of the roadway roof, which is not always horizontal and often features angled sections, traditional horizontal roof beams cannot accommodate the inclined roof, leading to uneven stress on the roof and premature damage, potentially causing safety accidents. Utility Model Content
[0003] To overcome the above-mentioned defects, the purpose of this utility model is to provide an inclined support unit bracket, which can meet the support requirements of some irregular roadways, improve the service life of equipment, and ensure construction safety.
[0004] To achieve the above objectives, this utility model provides an inclined support unit bracket, comprising a top beam and a support base; the support base is provided with a support unit body, the support unit body including a first support column and a second support column; the top beam includes a welded and fixed top beam plate, a top beam main reinforcement, and a column cap, the column cap having an arc-shaped connecting surface in the middle, the piston rod ends of the first support column and the second support column being spherical and respectively abutting against the arc-shaped connecting surface; along the length direction of the top beam plate, the column cap is provided with a fixing pin hole, and a fixing pin for connecting the support unit body and the column cap is inserted into the fixing pin hole.
[0005] Preferably, both the first support column and the second support column are provided with a return port at their upper parts, and the position of the return port is consistent with the length direction of the fixing pin.
[0006] Preferably, the openings at both ends of the fixing pin hole are flared.
[0007] Preferably, the column cap is provided with column cap ear plates on both sides, and the column cap ear plates are perpendicular to the main reinforcement of the top beam.
[0008] Preferably, a limiting block is also fixedly provided on the inner side of the main reinforcement of the top beam, and the limiting block is used to limit the tilt angle of the upper plate of the top beam.
[0009] Preferably, the first support column and the second support column are fixed on both sides by limiting plates, and the side of the support base is also hinged with an auxiliary support plate. A limiting cylinder is provided on the outside of the limiting plate, and the two ends of the limiting cylinder are respectively hinged to the limiting plate and the auxiliary support plate.
[0010] The beneficial technical effects achieved by this utility model after adopting the above technical solution are as follows:
[0011] 1. Due to the installation of a support unit consisting of a first and second support column, the top beam includes a welded and fixed top beam plate, main reinforcement bars, and column caps. The column caps have an arc-shaped connecting surface in the center. The piston rods of both the first and second support columns are spherical at the ends and abut against the arc-shaped connecting surface. The two support columns allow for adjustment of the top beam angle, making it more suitable for roadways with a certain angle of inclination. This enhances its practicality, ensures more balanced stress on the top beam, and thus improves its service life.
[0012] 2. The traditional support unit body has been improved, especially by changing the position of the return fluid port at the top of the first and second support columns to ensure that the position of the return fluid port is consistent with the length direction of the fixing pin. This change in position increases the modification cost slightly, but it directly avoids motion interference problems during installation and use. Especially in partially inclined roadways, it prevents collisions with pipelines and valves due to changes in angle during tilting, thus improving equipment safety. Furthermore, it eliminates the need for some side plates used for connections, simplifying installation.
[0013] 3. The first and second support columns are respectively limited by limiting plates on both sides, and limiting cylinders are hinged to the outer sides of the limiting plates. An auxiliary support plate is hinged to the other end of the limiting cylinders. Through the limiting cylinders and the auxiliary support plate, while ensuring the angle of the first and second support columns, the auxiliary support plate can change their support angle, increase the contact area at the bottom, and enhance stability.

[0023] To make the objectives, technical solutions, and advantages of this utility model clearer, the present utility model will be further described in detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely for explaining the present utility model and are not intended to limit the present utility model.
[0024] See Figures 1-5 This utility model provides an inclined support unit bracket, including a top beam 1 and a support base 3; the support base 3 is provided with a support unit body 2, which includes a first support column 21 and a second support column 22; the support unit body 2 generally contains two support columns, namely the first support column 21 and the second support column 22, and the two support columns are of the same type and can be interchanged. According to actual testing, Figure 1 In the main structure, the adjustable range of the inclined angle α along the length of the top beam 1 is generally -10° to 10°, which can be achieved by adjusting the height of the first support column 21 or the second support column 22. The adjustable range of the inclined angle β along the width of the side top beam 1 is -5° to 5°, determined by the actual roadway location, and is also achieved by adjusting the height of the first support column 21 or the second support column 22.
[0025] The top beam 1 includes a welded and fixed top beam upper plate 11, top beam main reinforcement 12, and column cap 13. The column cap 13 has an arc-shaped connecting surface 132 in the middle. The piston rod ends of the first support column 21 and the second support column 22 are both spherical and abut against the arc-shaped connecting surface 132. Along the length of the top beam upper plate 11, the column cap 13 has a fixing pin hole 133, into which a fixing pin for connecting the support unit body 2 and the column cap 13 is inserted. The spherical piston rod ends of the first support column 21 and the second support column 22 are connected to the arc-shaped connecting surface 132, and then the fixing pin is inserted to achieve hinged fixation. Because the piston rod ends are both spherical, they can be horizontally tilted. Figure 1 It can also be tilted left or right. Figure 2 To prevent interference with the movement of the fixing pin (not shown in the figure) when it rotates horizontally (i.e., along the length of the fixing pin) at a certain angle, the openings at both ends of the fixing pin hole 133 are flared, and the insertion direction of the fixing pin is consistent with the length direction of the top beam plate 11.
[0026] The first support column 21 and the second support column 22 of this invention are both provided with a return port 211 at their upper parts, and the position of the return port 211 is consistent with the length direction of the fixing pin. The return port 211 is an essential connecting part of the first support column 21 and the second support column 22, used to control the height, and is usually matched with a valve. This invention makes a slight improvement to the traditional first support column 21 and the second support column 22, not only increasing the height of the ball head, but also ensuring that the position of the return port 211 is consistent with the length direction of the fixing pin. In this way, the pipes, valves and other auxiliary connecting parts installed will not interfere with the movement when the top beam 1 swings, which can further ensure the safety of the equipment.
[0027] The column cap 13 of this invention has column cap ear plates 131 on both sides, and the column cap ear plates 131 are perpendicular to the main reinforcement 12 of the top beam. The column cap ear plates 131 are used to increase the contact area and ensure the rigidity of the top beam 1.
[0028] The first support column 21 and the second support column 22 of this utility model are fixed on both sides by limiting plates 23. An auxiliary support plate 25 is also hinged to the side of the support base. A limiting cylinder 24 is provided on the outer side of the limiting plate 23. The two ends of the limiting cylinder 24 are respectively hinged to the limiting plate 23 and the auxiliary support plate 25. The auxiliary support plate 25 is used to increase the contact area. The auxiliary support plate 25, together with the limiting cylinder 24, is used to adjust the angle of the first support column 21 and the second support column 22.
[0029] The inner side of the main reinforcement 12 of the top beam of this utility model is also fixedly provided with a limiting block 121, which is used to limit the tilt angle of the upper plate 11 of the top beam. The limiting block 121 is used to limit the rotation angle. Generally, during installation, the column cap 13 is welded and fixed first, and then a plate is welded on the main reinforcement 12 of the top beam as the limiting block 121. This can limit the rotation angle and prevent it from being limited by the limiting block 121 when the angle is too large. The included angle β of the width direction will be limited to ensure the support safety of the roadway and prevent the upper plate 11 of the top beam from failing to connect to the roof due to excessive swing angle of the top beam 1.
[0030] Of course, there may be other embodiments of this utility model. Without departing from the spirit and essence of this utility model, those skilled in the art can make various corresponding changes and modifications based on this utility model, but these corresponding changes and modifications should all fall within the protection scope of the appended claims of this utility model.
