Description

Technical Field

[0001] This utility model relates to the field of steel reinforcement laying technology; specifically, this utility model relates to a steel reinforcement laying device for tunnel lining construction. Background Technology

[0002] The tunnel rebar laying trolley is a special trolley used for rebar laying operations. It is easy to use and greatly improves the efficiency of rebar laying. In tunnel construction projects, waterproof and circumferential rebars need to be laid along the inner wall of the tunnel before concrete pouring. This requires operators to stand on the trolley to lay and tie the rebars. During the construction process, the labor intensity of workers is high, the construction quality cannot be guaranteed, and the rebars are also prone to puncturing the waterproof membrane, resulting in low construction quality.

[0003] Existing technology CN202221570982.4 provides an automatic rebar laying trolley, relating to the field of rebar laying technology. This automatic rebar laying trolley includes: a support plate; at least two support columns evenly distributed along its width are fixedly installed at both ends of the bottom of the support plate; a base plate is fixedly installed at the bottom end of multiple support columns on the same side; track wheels for driving the device along a track are installed at the bottom end of the base plate; side station plates are fixedly installed on the side of the two sets of support columns on the bottom sides of the support plate that are far apart from each other; at least two arc-shaped support frames evenly distributed along their length are installed on the top of the support plate; fixing blocks are fixedly installed between the two ends of each arc-shaped support frame and the two side station plates; at least two clamping components for pressing the rebar against the tunnel arc-shaped wall are installed on the side of the arc-shaped support frame away from the support plate. This improves the laying quality of the device, and the device can lay multiple rebars simultaneously, thus improving the laying efficiency.

[0004] However, in the above-mentioned technology, the tightening component needs to be operated multiple times separately when laying the steel bars, which increases the labor intensity of steel bar laying. Utility Model Content

[0020] The technical solutions in the embodiments of this utility model will be clearly and completely described below. Obviously, the described embodiments are only some embodiments of this utility model, and not all embodiments. Based on the embodiments of this utility model, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of this utility model.

[0021] like Figures 1 to 3 As shown, a typical embodiment of the present invention provides a steel bar laying device for tunnel lining construction, including: a laying trolley 1, a hydraulic cylinder 2 and a placement sleeve 3; the hydraulic cylinder 2 is fixedly installed inside the laying trolley 1, the output end of the hydraulic cylinder 2 penetrates through the top surface of the laying trolley, and the output end of the hydraulic cylinder 2 is provided with a placement sleeve 3, which is designed in an arc shape, and the steel bar can be placed into the placement sleeve 3.

[0022] When in use, the reinforcing bar is placed in the placement sleeve 3. The arc-shaped placement sleeve 3 can support the arc-shaped reinforcing bar. The hydraulic cylinder 2 is activated, which makes the placement sleeve 3 move the reinforcing bar towards the top of the tunnel, so that the reinforcing bar contacts the inner wall of the tunnel and is stably installed on the inner wall of the tunnel.

[0023] There are two placement sleeves 3, and a rotating rod 4 is rotatably installed at the bottom of each of the two placement sleeves 3. The bottom ends of the two rotating rods 4 are rotatably connected to each other, and the bottom end of the rotating rod 4 is connected to the output end of the oil cylinder 2.

[0024] When the two placement sleeves 3 move upward, the rotating rod 4 moves upward. When the reinforcing bar contacts the inner wall of the tunnel, the rotating rod 4 rotates, allowing the placement sleeves 3 to move to both sides of the reinforcing bar and enabling the reinforcing bar to contact the inner wall of the tunnel more stably.

[0025] Wheel frames 3-1 are slidably installed on both sides of the placement sleeve 3, and rollers 3-2 are rotatably installed on both sides of the wheel frame 3-1, so that the wheel frame 3-1 can contact the reinforcing bar.

[0026] When the roller 3-2 is not in contact with the inner wall of the tunnel, the wheel frame 3-1 can restrict the two sides of the steel bar to prevent the steel bar from falling out of the placement sleeve 3, making the steel bar more stable when it rises. At the same time, when the roller 3-2 is in contact with the inner wall of the tunnel, the roller 3-2 can make it easier for the placement sleeve 3 to move towards the two sides of the steel bar.

[0027] Meanwhile, a limiting block is fixedly installed on the wheel frame 3-1, and a limiting groove is opened on the placement sleeve 3. The limiting block is slidably installed in the limiting groove, which can effectively prevent the wheel frame 3-1 from deflecting from the placement sleeve 3.

[0028] A rotating seat 3-3 is fixedly installed at the bottom of the placement sleeve 3, and a rotating rod 4 is rotatably installed on the rotating seat 3-3. A rotating ring 3-4 is rotatably installed at the bottom of the wheel frame 3-1, and the rotating ring 3-4 is sleeved on the rotating seat 3-3.

[0029] When roller 3-2 contacts the inner wall of the tunnel, cylinder 2 continues to move upward, which can cause wheel frame 3-1 and placement sleeve 3 to shift, so that when the steel bar contacts the inner wall of the tunnel, it can effectively prevent the steel bar from falling off the wheel frame 3-1.

[0030] A first spring 3-5 is fixedly installed on the swivel 3-4, and the top end of the first spring 3-5 is fixedly installed inside the wheel frame 3-1.

[0031] When the wheel frame 3-1 moves, the first spring 3-5 is compressed, allowing the wheel frame 3-1 to move. When the first spring 3-5 is no longer under force, the first spring 3-5 returns to its original position, which can position the wheel frame 3-1 at the top and prevent the steel bar from falling off the placement sleeve 3.

[0032] A mounting bracket 3-6 is fixedly installed on one side of the two adjacent placement sleeves 3. An inclined block 3-8 is slidably installed inside the mounting bracket 3-6, and the inclined block 3-8 can contact the bottom end of the wheel frame 3-1.

[0033] A sliding block 3-9 is fixedly installed on the outer wall of the inclined block 3-8. A groove 3-7 is provided on the mounting bracket 3-6. The sliding block 3-9 is slidably installed in the groove 3-7. A second spring 3-91 is fixedly installed between the groove 3-7 and the sliding block 3-9.

[0034] When the two placement sleeves 3 come into contact, the end faces of the two inclined blocks 3-8 come into contact, causing the inclined blocks 3-8 and the placement sleeves 3 to shift. The end face of the inclined block 3-8 comes into contact with the bottom surface of the wheel frame 3-1, locking the wheel frame 3-1 and allowing the placement sleeves 3 to support the steel bars more stably.

[0035] At the same time, when the inclined block 3-8 moves, it can stretch the second spring 3-91. When the second spring 3-91 is not under force, it can reset the inclined block 3-8, so that the inclined block 3-8 is in the farthest state, which makes it easier for the two inclined blocks 3-8 to contact.

[0036] The placement sleeve 3 is provided in multiple sets, and a moving block 5 is provided between two adjacent sets of placement sleeve 3. A stabilizing rod 5-1 is rotatably installed at both ends of the moving block 5. The top end of the stabilizing rod 5-1 contacts the rotating rod 4, and a torsion spring is provided at the bottom end of the stabilizing rod 5-1. The moving block 5 is fixedly connected to the output end of the oil cylinder 2.

[0037] When the hydraulic cylinder 2 is activated, the hydraulic cylinder 2 drives the moving block 5 to move upward, and the moving block 5 drives the rotating rod 4 to move upward. When the wheel frame 3-1 is not in contact with the inner wall of the tunnel, the stabilizing rod 5-1 remains in contact with the rotating rod 4, which allows the steel bar to remain stable when moving upward. When the wheel frame 3-1 contacts the inner wall of the tunnel, the rotating rod 4 rotates and presses down the stabilizing rod 5-1, so that the rotating rod 4 remains stable when rotating, and the steel bar can remain in contact with the inner wall of the tunnel.

[0038] The technical scope of this utility model is not limited to the contents of the above description. Those skilled in the art can make various modifications and variations to the above embodiments without departing from the technical concept of this utility model, and all such modifications and variations should fall within the scope of this utility model.
