Description

Technical Field

[0001] The utility model relates to a positioning device, in particular to a steel bar welding positioning device for secondary lining construction of a mountain tunnel, belonging to the technical field related to secondary lining construction of a mountain tunnel. Background Art

[0002] The secondary lining construction of mountain tunnels is an important part of tunnel engineering. In the secondary lining construction of mountain tunnels, the secondary lining trolley is first moved to the designated position, and then the steel structure of the tunnel secondary lining is installed. Secondly, various embedded parts are installed according to the design requirements, and then concrete is poured by pumping or other methods. Finally, after the concrete reaches a certain strength, it is demolded and cured. At this stage, it is necessary to cast the secondary lining on the inner side of the initial support of the tunnel to further enhance the stability and durability of the tunnel.

[0003] The steel bar structure in the secondary lining construction of mountain tunnels is generally mesh-shaped. The mesh steel bar structure has the advantages of enhancing the integrity and rigidity of the secondary lining structure, enabling it to better resist external forces, and evenly distributing the load above the tunnel to the entire steel bar mesh, improving the bearing capacity of the structure, etc. However, when laying the steel bar structure, in order to ensure the stability of subsequent steel bar welding, iron wires are generally screwed at the vertical and horizontal intersections between multiple steel bars. However, a large number of steel bars are used in the construction of the secondary lining of mountain tunnels. It is time-consuming to screw the iron wires on the intersections one by one, and it increases the labor intensity of the workers, making the process before and after welding longer, indirectly increasing the welding time, and the iron wire cannot be recycled after use, resulting in a waste of resources. If the steel bars are not fixed, they need to be manually fixed in position during welding, affecting the overall construction efficiency.

[0029] The following will describe the implementation methods of the present application in detail with the help of accompanying drawings and examples, so that the implementation process of how the present application uses technical means to solve technical problems and achieve technical effects can be fully understood and implemented accordingly.

[0030] like Figure 1-Figure 8 As shown, the steel bar welding positioning device for secondary lining construction of mountain tunnel provided in this embodiment comprises

[0031] The clamping mechanism 1 includes two clamping mechanisms 1, and the two clamping mechanisms 1 are respectively used to clamp the No. 1 steel bar 2 and the No. 2 steel bar 200 placed perpendicular to each other. After clamping, the two clamping mechanisms 1 are fixed to each other, that is, the vertical relationship between the No. 1 steel bar 2 and the No. 2 steel bar 200 is stabilized by placing the two clamping mechanisms 1 at right angles.

[0032] The buckle mechanism 3 is used to release and fix the clamping state of the clamping mechanism 1 on the No. 1 steel bar 2 and the No. 2 steel bar 200. The buckle mechanism 3 is used to facilitate the clamping and releasing of the clamping mechanism 1 on the No. 1 steel bar 2 or the No. 2 steel bar 200.

[0033] A connecting arm No. 1 4 and a connecting arm No. 2 5 are respectively connected to the side walls of the two clamping mechanisms 1, and the connecting arm No. 1 4 and the connecting arm No. 2 5 are placed at right angles and are slidably connected to each other. The connecting arm No. 1 4 and the connecting arm No. 2 5 are placed at right angles to better fix the relative positions of the two clamping mechanisms 1, and to better adapt to the vertical relationship between the No. 1 steel bar 2 and the No. 2 steel bar 200.

[0034] The No. 1 threaded rod 12 is used to adjust the parallel distance between the No. 1 connecting arm 4 and the No. 2 connecting arm 5, and is better suitable for the height difference between the No. 1 steel bar 2 and the No. 2 steel bar 200.

[0035] One end of the No. 1 connecting arm 4 is fixedly connected to the sliding track 11, one end of the No. 2 connecting arm 5 is slidably connected to the sliding track 11, the No. 1 threaded rod 12 is threadedly connected to the sliding track 11, and one end of the No. 1 threaded rod 12 is rotatably connected to one end of the No. 2 connecting arm 5, a square frame 13 is fixedly connected to the lower end surface of the sliding track 11, and a No. 2 threaded rod 14 is threadedly connected to the square frame 13, and the No. 2 threaded rod 14 is used to support the connection between the No. 1 connecting arm 4 and the No. 2 connecting arm 5.

[0036] Further, such as Figure 2 as well as Figure 6 As shown, the clamping mechanism 1 includes a device box 100, a double-sided rack 101, a rotating gear 102, a connecting plate 103, a clamping plate 104 and a push rod 105. The double-sided rack 101 is slidably connected in the device box 100. There are two rotating gears 102 and both are rotatably connected to the device box 100. The two rotating gears 102 are respectively located on both sides of the double-sided rack 101 and mesh with the double-sided rack 101. One end of the connecting plate 103 is connected to the rotating gear 102. The clamping plate 104 is hinged on the other end of the connecting plate 103. The push rod 105 is fixedly connected to the lower end surface of the double-sided rack 101. The No. 1 steel bar 2 or the No. 2 steel bar 2 00 will squeeze and push the top rod 105. After being subjected to the force, the top rod 105 will drive the double-sided rack 101 to move upward in the device box 100, and then drive the two rotating gears 102 to rotate toward the double-sided rack 101. When the rotating gear 102 rotates, it will drive one end of the connecting plate 103 to rotate with the center point of the rotating gear 102 as the center of the circle, so that the clamping plate 104 moves synchronously with the connecting plate 103. After the two clamping plates 104 move synchronously toward the No. 1 steel bar 2 or the No. 2 steel bar 200, the No. 1 steel bar 2 or the No. 2 steel bar 200 is gradually clamped and fixed.

[0037] Among them, Figure 6 As shown, a No. 3 threaded rod 6 is threadedly connected to the device box 100, and the No. 3 threaded rod 6 is used to limit the sliding of the double-sided rack 101. When the double-sided rack 101 slides upward, under the action of the No. 3 threaded rod 6, the double-sided rack 101 is limited, so that the double-sided rack 101 will not slide upward unlimitedly, and it will also be convenient to deal with steel bars of different diameters.

[0038] Furthermore, Figure 1As shown, the snap mechanism 3 includes a ratchet bar 301 fixedly connected to the double-sided rack 101, a long groove 302 opened on the device box 100, a moving block 303 slidably connected to the long groove 302, a telescopic spring 305 fixedly connected to the long groove 302, and a pawl member 304 rotatably connected to the moving block 303, the telescopic spring 305 facilitates the resetting of the pawl member 304 after movement, the pawl member 304 is movably engaged with the ratchet bar 301, and the two ends of the telescopic spring 305 are respectively fixedly connected to the long groove 302 and the moving block 303, the double-sided rack 101 moves upward in the device box 100, and the ratchet bar 301 is driven to move synchronously during the movement, and the ratchet bar 301 moves upward in one direction under the action of the pawl member 304 during the movement.

[0039] Among them, Figure 5-Figure 8 As shown, the pawl member 304 is fixedly connected with the limiting groove 7 and the pushing spring 8, and one end of the pushing spring 8 is fixedly connected to the inner wall of the device box 100. The pushing spring 8 makes the engagement state between the pawl member 304 and the ratchet bar 301 more stable. A stop block 9 is fixedly connected to the inner wall of the device box 100, and the stop block 9 is in contact with the limiting groove 7. A pin 10 is movably engaged in the limiting groove 7. When the clamping mechanism 1 is no longer in use, only the pin 10 needs to be pulled out to pull the ratchet bar 301 downward, and during the movement, the teeth on the ratchet bar 301 will continuously squeeze and push the pawl member 304, and the pawl member 304 will not move away from the ratchet bar 301 under the action of the moving block 303.

[0040] like Figure 1-Figure 8As shown, the principle of the steel bar welding positioning device for the secondary lining construction of a mountain tunnel provided by this embodiment is as follows: when in use, the two clamping mechanisms 1 are clamped at appropriate positions with the No. 1 steel bar 2 and the No. 2 steel bar 200 respectively. During the clamping process, the No. 1 steel bar 2 or the No. 2 steel bar 200 will squeeze and push the top rod 105. After being subjected to the force, the top rod 105 will drive the double-sided rack 101 to move upward in the device box 100, and will drive the ratchet bar 301 to move synchronously during the movement. When the ratchet bar 301 moves, the ratchet bar 301 moves upward in one direction under the action of the pawl member 304. When the double-sided rack 101 moves, it will drive the two rotating gears 102 to rotate in the direction of the double-sided rack 101. While the rotating gear 102 rotates, Drive one end of the connecting plate 103 to rotate with the center point of the rotating gear 102 as the center, so that the clamping plate 104 moves synchronously with the connecting plate 103. After the two clamping plates 104 move synchronously toward the No. 1 steel bar 2 or the No. 2 steel bar 200, the No. 1 steel bar 2 or the No. 2 steel bar 200 is gradually clamped and fixed. Under the action of the No. 1 connecting arm 4 and the No. 2 connecting arm 5, the two clamping mechanisms 1 are arranged at right angles, so that the No. 1 steel bar 2 and the No. 2 steel bar 200 are arranged at right angles. If necessary, another structural device can be set up and connected to the other side of the intersection of the No. 1 steel bar 2 or the No. 2 steel bar 200. At this time, the intersection of the No. 1 steel bar 2 and the No. 2 steel bar 200 can be welded, and the device structure can be reused.
