Abstract
Description
Technical Field
[0001] The utility model belongs to the technical field of steel mesh welding, and specifically relates to an auxiliary welding bracket for underground mine support steel mesh. Background Art
[0002] Steel mesh is a square mesh steel product made of several transverse and longitudinal bars welded perpendicularly to each other. It is mainly used in beams, columns and floor slabs of houses, concrete pavements, bridge deck paving, tunnel linings, underground mine support and other fields. Steel mesh is usually welded in a factory by a steel mesh welding machine. The transverse and longitudinal bars are arranged at right angles to each other at a certain interval, and the welding machine performs high-resistance pressure welding on all intersections to form it.
[0003] However, such steel meshes generally have problems such as low welding reliability and low welding stability at the intersections of transverse and longitudinal reinforcements. For underground mine support, the structural strength of the steel mesh affects the support strength, stability and safety of the entire support structure. Therefore, before such steel meshes are used in underground mine support construction, the welding intersections of the steel meshes need to be reinforced by welding.
[0004] At present, for the reinforcement welding operation of underground mine support steel mesh, the steel meshes are usually reinforced and welded from top to bottom on the top of the steel mesh pile stacked in a horizontal state, which makes the welding intersections of the steel meshes on the lower layer too hidden, and due to limited operating space, only 1-2 steel meshes on the top layer can be welded each time, which leads to the problems of frequent handling of steel meshes, high labor intensity, time-consuming and labor-intensive, as well as high welding difficulty and low welding efficiency. Utility Model Content
[0005] In order to solve or partially solve the problems existing in the related technology, the utility model provides an auxiliary welding bracket for underground mine support steel mesh, which can push multiple steel meshes to the right to a state where the longitudinal reinforcements are sequentially staggered in the vertical plane, so that the welding intersections of the multiple steel meshes are fully exposed to facilitate reinforcement welding of multiple steel meshes at one time, reducing the labor intensity of carrying the steel meshes, saving time and effort, effectively reducing the difficulty of reinforcement welding, and effectively improving welding efficiency.
[0006] The present application provides an auxiliary welding bracket for underground support steel mesh for mines, including a support frame, a pad, a fixing rod, a sleeve, a push plate, and a universal wheel. The support frame is a rectangular frame structure, and pads are horizontally and symmetrically installed at the left and right ends of one side of the bottom of the support frame. The steel mesh to be welded is placed on the pad and tilted against the support frame.
[0007] A fixing rod is vertically installed at the bottom of the support frame, and a freely rotatable sleeve is mounted on the fixing rod. A push plate is horizontally installed on the outer wall of the sleeve, and a universal wheel is installed at the bottom of the outer end of the push plate. The push plate can swing in the horizontal plane between the two pads with the fixing rod as the center, and when the push plate is rotated to the right, the right side surface of the push plate can contact the part of any longitudinal reinforcement of the steel mesh that exceeds the lowest transverse reinforcement. When the push plate is rotated to the right to the maximum swing angle position, the right side surface of the push plate abuts against one of the longitudinal reinforcements of all the steel meshes.
[0008] Optionally, in one solution, the width of the pad is greater than the horizontal spacing between two adjacent longitudinal bars of the steel mesh, and the two pads are always in contact with the lower end of at least one longitudinal bar of the steel mesh respectively and simultaneously.
[0009] Optionally, in one solution, the horizontal height of the upper surface of the push plate is not higher than the horizontal height of the lower surface of the lowest transverse reinforcement of the steel mesh.
[0010] Optionally, in one solution, a positioning sleeve is vertically installed at a position where the outer end of the push plate does not contact the steel mesh, a positioning pin is provided in the positioning sleeve, and a pin groove matching the positioning pin is provided on the ground below the position where the push plate has a maximum swing angle.
[0011] Optionally, in one embodiment, a non-slip handle is provided at a position of the push plate located outside the positioning sleeve.
[0012] Beneficial effects of the utility model:
[0013] The utility model provides a rotatable pushing plate under the steel mesh to push the steel mesh, so that multiple steel meshes can be pushed to the right to a state where the longitudinal reinforcements are sequentially staggered in the vertical plane, so that the welding intersections of the transverse reinforcements and the longitudinal reinforcements of the multiple steel meshes are fully exposed, thereby facilitating the reinforcement welding operations on the welding intersections of multiple steel meshes at one time, and multiple steel meshes can be carried and welded at one time, which reduces the labor intensity of carrying the steel meshes, saves time and effort, effectively reduces the difficulty of reinforcement welding, and can effectively improve welding efficiency.

[0026] At present, for the reinforcement welding operation of the steel mesh 100 for underground mine support, the method of reinforcing and welding each steel mesh 100 from top to bottom is adopted. The welding intersections of the steel mesh 100 located in the lower layer are too hidden, and there are problems such as the need to frequently move the steel mesh 100, high labor intensity, time-consuming and labor-intensive, high welding difficulty and low welding efficiency.
[0027] In view of the above problems, the present application makes improvements and innovations and proposes the following embodiments.
[0028] In some embodiments, see Figure 1-Figure 5 ,in Figure 2 , Figure 3 Only the state of a part of the steel mesh 100 on the auxiliary welding bracket is shown, and an auxiliary welding bracket for underground support steel mesh for mining is provided, including a support frame 1, a pad 2, a fixing rod 3, a sleeve 4, a push plate 5, and a universal wheel 6. The support frame 1 is a rectangular frame structure, and the pads 2 are horizontally and symmetrically installed on the left and right ends of one side of the bottom of the support frame 1. The steel mesh 100 to be welded is placed on the pad 2 and tilted against the support frame 1. Specifically, when the push plate 5 is not rotated, all the steel meshes 100 are neatly placed on the pad 2 and tilted against the support frame 1 in a state where the transverse reinforcement 101 and the longitudinal reinforcement 102 are aligned respectively and the two adjacent longitudinal reinforcements 102 cross the push plate 5.
[0029] Among them, a fixing rod 3 is vertically installed at the bottom of the support frame 1, and a freely rotatable sleeve 4 is mounted on the fixing rod 3. A push plate 5 is horizontally installed on the outer wall of the sleeve 4, and a universal wheel 6 is installed at the bottom of the outer end of the push plate 5. The push plate 5 can swing in the horizontal plane between the two pads 2 with the fixing rod 3 as the center, and when the push plate 5 is rotated to the right, the right side surface of the push plate 5 can contact the part of any longitudinal reinforcement 102 of the steel mesh 100 that exceeds the lowest transverse reinforcement 101, so that the longitudinal reinforcement 102 of the steel mesh 100 that exceeds the lowest transverse reinforcement 101 is pushed to the right by rotating the push plate 5 to the right, so that each steel mesh 100 is pushed to the right in turn as the rightward rotation angle of the push plate 5 increases, so that each steel mesh 100 is in a state where the longitudinal reinforcement 102 is displaced in turn in the vertical plane, such as Figure 4 , Figure 5 As shown, the welding intersections of the transverse reinforcement 101 and the longitudinal reinforcement 102 of multiple steel meshes 100 can be fully exposed. When the push plate 5 rotates to the right to the maximum swing angle position, the right side surface of the push plate 5 abuts against one of the longitudinal reinforcements 102 of all the steel meshes 100. At this time, all the steel meshes 100 placed on the auxiliary welding bracket are pushed to the right in turn by the push plate 5, so that all the steel meshes 100 are in a state where the longitudinal reinforcements 102 are displaced in turn in the vertical plane.
[0030] In this way, by arranging a rotatable push plate 5 under the steel mesh 100, and by rotating the push plate 5 to the right, the steel mesh 100 to be welded is pushed to the right until the longitudinal reinforcement 102 is sequentially displaced in the vertical plane, so that the welding intersections of the transverse reinforcement 101 and the longitudinal reinforcement 102 of multiple steel meshes 100 are fully exposed, so that it is convenient for the staff to perform reinforcement welding operations on the welding intersections of multiple steel meshes 100 in batches at one time from the cavity formed by the intersection of the transverse reinforcement 101 and the longitudinal reinforcement 102, until the reinforcement welding of each welding intersection of a single batch of steel meshes 100 is completed, multiple steel meshes 100 can be transported and welded at one time, which reduces the labor intensity of transporting the steel mesh 100, saves time and effort, effectively reduces the difficulty of reinforcement welding, can effectively improve welding efficiency, and solves the problem caused by the existing reinforcement welding method that the welding intersections of the steel mesh 100 located in the lower layer are too hidden.
[0031] In this embodiment, by installing a universal wheel 6 at the bottom of the outer end of the push plate 5, on the one hand, the push plate 5 can be effectively supported to ensure that the push plate 5 remains horizontal, thereby ensuring that each steel mesh 100 can be accurately pushed, and on the other hand, the resistance during the rotation of the push plate 5 can be effectively reduced, so as to reduce the difficulty of pushing the push plate 5 and improve the convenience of operation. In specific applications, the push plate 5 and the fixed rod 3 can also be connected through a bearing to improve the smoothness of rotation between the push plate 5 and the fixed rod 3.
[0032] In some embodiments, see Figure 2, Figure 3 The width of the pad 2 is greater than the horizontal spacing between two adjacent longitudinal bars 102 of the steel mesh 100. The two pads 2 are always in contact with the lower end of at least one longitudinal bar 102 of the steel mesh 100 respectively, so as to ensure that when the push plate 5 is pushed to the right, the steel mesh 100 maintains a state in which at least one longitudinal bar 102 is in contact with the pad 2 at both ends, and ensures that the steel mesh 100 is always in a state of being stably supported by the two pads 2, so that all the steel meshes 100 can maintain balance, so as to avoid the situation in which some steel meshes 100 are tilted due to the separation of the longitudinal bars 102 from the pad 2, and further ensure that the steel mesh 100 is in a state in which the longitudinal bars 102 are displaced in sequence in the vertical plane, so as to facilitate the normal reinforcement welding operation.
[0033] In some embodiments, see Figure 3 The horizontal height of the upper surface of the push plate 5 is not higher than the horizontal height of the lower surface of the lowest transverse reinforcement 101 of the steel mesh 100, so as to ensure that the steel mesh 100 is always in a state of being supported only by the two pads 2, and avoid the steel mesh 100 tilting to the left or right due to the lowest transverse reinforcement 101 being pushed upward by the push plate 5, so as to facilitate all the steel meshes 100 to maintain balance, and then ensure that the steel mesh 100 is in a state where the longitudinal reinforcement 102 is sequentially displaced in the vertical plane; in addition, it can effectively prevent the push plate 5 from being pressed by the steel mesh 100, so as to facilitate the push plate 5 to rotate smoothly to push the steel mesh 100 to move right and displace.
[0034] In some embodiments, see Figure 1-Figure 3 A positioning sleeve 7 is vertically installed at the position where the outer end of the push plate 5 does not contact the steel mesh 100. A positioning pin 8 is arranged in the positioning sleeve 7. A pin groove matching the positioning pin 8 is provided on the ground below the maximum swing angle position of the push plate 5, so that when the push plate 5 is rotated to the right to the maximum swing angle position, the push plate 5 can be limited by inserting the positioning pin 8 into the pin groove to avoid damaging the state of the steel mesh 100 due to accidental touching of the push plate 5 during the reinforcement welding process and interfering with the welding operation, so as to ensure the normal progress of the reinforcement welding operation and ensure the welding efficiency and welding quality.
[0035] In some embodiments, see Figure 1-Figure 3 A non-slip handle 9 is provided at the position of the push plate 5 outside the positioning sleeve 7, so that the push plate 5 can be rotated and reset by the non-slip handle 9, which is convenient, safe and efficient to operate.
[0036] Finally, it should be noted that although the embodiments of the utility model have been shown and described above, it can be understood that the above embodiments are exemplary and cannot be understood as limitations on the utility model. Ordinary technicians in the field can make changes, modifications, substitutions and variations to the above embodiments within the scope of the utility model, which should all be included in the scope of protection of this application.
