Technical Field
[0001] This utility model relates to the technical field of steel reinforcement cage placement device, specifically to an auxiliary device for placing steel reinforcement cages into the formwork of tunnel segments. Background Technology
[0002] Tunnel boring machine (TBM) segments are the main assembly components in TBM construction. They form the innermost barrier of the tunnel, resisting soil pressure, groundwater pressure, and other special loads. TBM segments are manufactured using TBM segment molds. Each TBM segment contains a steel reinforcement cage, which must be pre-transferred into the mold during the manufacturing process.
[0003] The existing technology has the following problems:
[0004] Currently, in auxiliary equipment for placing the steel reinforcement cage into the formwork of tunnel segments, a crane is used to lift the steel reinforcement cage and then place it into the mold. This method has several drawbacks. During operation, the crane is prone to swaying while lifting the steel reinforcement cage, requiring workers to constantly adjust its position to facilitate placement. This repeated adjustment is cumbersome and reduces the efficiency of steel reinforcement cage placement. Furthermore, the lack of a cleaning mechanism after use leaves concrete residue in the mold, requiring manual cleaning and increasing labor costs.
[0005] Therefore, we need an auxiliary device for inserting the steel reinforcement cage into the formwork of tunnel segments to solve the above problems. Utility Model Content
[0006] This utility model provides an auxiliary device for inserting the steel reinforcement skeleton of tunnel segment into the formwork, in order to solve the problems mentioned in the background art.
[0007] To solve the above-mentioned technical problems, the technical solution adopted by this utility model is as follows:
[0008] A shield tunnel segment reinforcement skeleton placement auxiliary device includes a base, a mold is fixedly connected to the upper surface of the base, two guide components are fixedly connected to the left and right sides of the upper surface of the base, guide plates are fixedly connected to the front and rear center of the upper surface of the mold, a liquid storage tank is fixedly connected to the front side of the upper surface of the base, and a rubber sealing plug is inserted through the center of the front of the liquid storage tank.
[0009] Both the left and right guide components include an L-shaped support base. The L-shaped support base has a T-shaped groove in the vertical direction. A T-shaped slider is slidably connected inside the T-shaped groove. A hydraulic cylinder is fixedly connected to the outer surface of the T-shaped slider. A plate is fixedly connected to the output end of the hydraulic cylinder.
[0010] A further improvement of this utility model is that: a motor is fixedly connected to the rear side of the upper surface of the T-shaped slider, a gear is fixedly connected to the output shaft of the motor, a rack is meshed with the outer surface of the gear, and the outer surface of the rack is fixedly connected to the inner side of the T-shaped groove.
[0011] A further improvement of this utility model is that the left and right guide components and the front and rear guide plates form a cross shape.
[0012] A further improvement of this utility model is that: a liquid outlet pipe is fixedly connected through the middle of the upper surface of the liquid storage tank, the outer surface of the liquid outlet pipe is fixedly connected through the interior of the front guide plate, and a pump body is fixedly connected to the lower end of the liquid outlet pipe.
[0013] A further improvement of this utility model is that a partition plate is fixedly connected to the lower surface of the pump body, and the outer surface of the partition plate is fixedly connected to the middle of the inner wall of the liquid storage tank.
[0014] A further improvement of this utility model is that the outer surface of the partition plate forms two cavities with the inner wall of the liquid storage tank.
[0015] A further improvement of this utility model is that: pipes are fixedly connected through the lower left and right sides of the liquid storage tank, the outer surfaces of the left and right pipes are fixedly connected through the interior of the mold, and an inlet pipe is fixedly connected through the right side of the upper surface of the liquid storage tank, with a valve provided on the outer surface of the inlet pipe.
[0016] A further improvement of this utility model is that: a connecting plate 1 is fixedly connected to the middle of the lower surface of the inner wall of the liquid storage tank, and connecting plates 2 are fixedly connected to the left and right sides of the connecting plate 1 in a mirror-like manner, and the connecting plate 1 and the connecting plate 2 are in a direct triangular block state.
[0017] Due to the adoption of the above technical solution, the technological progress achieved by this utility model compared to the prior art is as follows:
[0018] 1. This utility model provides an auxiliary device for inserting the steel reinforcement skeleton into the mold of a tunnel segment. After being lifted by a crane, the front and rear guide plates facilitate the obstruction of the steel reinforcement skeleton, preventing any possible back-and-forth swaying. Then, by starting the motor and cooperating with gears and racks, the hydraulic cylinder is activated, causing the hydraulic cylinder to contact and clamp the steel reinforcement skeleton. Then, the motor is turned off, and the crane slowly lowers the steel reinforcement skeleton. During the slow lowering process, the steel reinforcement skeleton will not move in position, thus possessing stability, and thus enters the mold. Due to the design of this structure, the steel reinforcement skeleton will not move in position after being lifted by the crane, eliminating the need for position adjustment of the steel reinforcement skeleton and facilitating its rapid entry into the mold.
[0019] 2. This utility model provides an auxiliary device for inserting the steel reinforcement skeleton of shield tunnel segments into the mold. After use, the cleaning fluid above the partition plate can be drawn through the liquid outlet pipe and sprayed into the inside of the mold through the pump body, thereby soaking and cleaning the inside of the mold. At this time, a sealing plug is set in the pipe, and the cleaning liquid is discharged into the area below the partition plate through the pipe. The cleaning fluid entering the area below the partition plate contains concrete residue, which flows into the connecting plate and accumulates, facilitating the subsequent cleaning effect and reducing the labor of workers.

[0025] To make the technical means, creative features, objectives and effects of this utility model easier to understand, the present utility model will be further described below in conjunction with specific embodiments.
[0026] Example 1: As Figures 1 to 4As shown, this utility model provides an auxiliary device for inserting the steel reinforcement skeleton of a tunnel lining segment, including a base 1. The base 1 facilitates the installation of a liquid storage tank 5, guide components 3, and a mold 2. The mold 2 is fixedly connected to the upper surface of the base 1, allowing the steel reinforcement skeleton to be placed inside. The mold 2 is sealed by a mold cover. Concrete is poured into the feed pipe in the mold cover and then into the mold 2. After the concrete solidifies, it forms a tunnel lining segment. Two guide components 3 are fixedly connected to the left and right sides of the upper surface of the base 1, and guide plates are fixedly connected to the center of the front and rear sides of the upper surface of the mold 2. 4. The coordinated use of guide plate 4 and guide component 3 ensures stability during the process of lifting the steel reinforcement skeleton into mold 2, facilitating rapid mold placement. A liquid storage tank 5 is fixedly connected to the front side of the upper surface of base 1. The liquid storage tank 5 facilitates the cleaning of concrete residue inside mold 2 after use. A rubber sealing plug 6 is inserted through the center of the front of the liquid storage tank 5. Pulling out the rubber sealing plug 6 allows the cleaning liquid and concrete residue to be discharged together. The cleaning liquid is a chemical softener, which facilitates the soaking, softening, and removal of hardened concrete that is bonded to mold 2, making cleaning easier.
[0027] Both left and right guide components 3 include L-shaped support seats 31. T-shaped grooves 32 are vertically formed in the L-shaped support seats 31, and T-shaped sliders 33 are slidably connected inside the T-shaped grooves 32. This structure allows the T-shaped sliders 33 to slide up and down. A hydraulic cylinder 34 is fixedly connected to the outer surface of the T-shaped sliders 33, and a plate 35 is fixedly connected to the output end of the hydraulic cylinder 34. Activation of the hydraulic cylinder 34 drives the plate 35 to push and clamp the steel reinforcement skeleton, ensuring the stability of the steel reinforcement skeleton and preventing lateral movement, thus facilitating subsequent mold placement. A motor 36 is fixedly connected to the rear side of the upper surface of the T-shaped sliders 33. Furthermore, the motor 36 is electrically powered by wires. The motor 36 is connected to a gear 37, and a rack 38 is meshed with the outer surface of the gear 37. The outer surface of the rack 38 is fixedly connected to the inner side of the T-shaped slide 32. This structure allows the T-shaped slider 33 to move upward. When it moves to the appropriate position, the hydraulic cylinder 34 is activated to clamp the steel reinforcement cage. Then the motor 36 is turned off. As the crane lowers the steel reinforcement cage, the T-shaped slider 33 also moves downward. The left and right guide components 3 and the front and rear guide plates 4 form a cross shape. The cross shape formed by the two provides stability when the steel reinforcement cage is placed into the mold, and will not cause the steel reinforcement cage to move in the front, back, left, or right.
[0028] Example 2: Figures 1 to 4As shown, a liquid outlet pipe 52 is fixedly connected through the middle of the upper surface of the liquid storage tank 5. The liquid outlet pipe 52 facilitates the delivery of cleaning fluid. The outer surface of the liquid outlet pipe 52 is fixedly connected through the interior of the front guide plate 4. In addition, the end face of the liquid outlet pipe 52 is horizontal with the surface of the front guide plate 4, which facilitates the insertion of the steel reinforcement frame and prevents obstruction. A pump body 51 is fixedly connected to the lower end of the liquid outlet pipe 52 and is electrically connected to the power supply via an electrical wire, which facilitates the start of the pump body 51 to draw cleaning fluid from the inner cavity above the partition plate 53. A partition plate 53 is fixedly connected to the lower surface of the pump body 51. The outer surface of the partition plate 53 is fixedly connected to the middle of the inner wall of the liquid storage tank 5. The upper and lower parts of the outer surface of the partition plate 53 and the inner wall of the liquid storage tank 5 form two cavities. To facilitate the separate storage of cleaning solutions before and after use, pipes 54 are fixedly connected to the lower left and right sides of the storage tank 5. The outer surfaces of the left and right pipes 54 are fixedly connected to the interior of the mold 2. The pipes 54 facilitate the flow of cleaning solution into the storage tank 5. Before cleaning, a sealing rubber is inserted into the pipes 54 to form a seal, preventing concrete from entering the mold 2 during use and preventing the cleaning solution from leaking out when the mold 2 is soaked after use. After soaking, the sealing rubber is removed, allowing the cleaning solution soaked in the mold 2 to flow into the storage tank 5 through the pipes 54. The upper right side of the storage tank 5 is fixedly connected to... The liquid inlet pipe 57 is connected, and a valve is provided on the outer surface of the liquid inlet pipe 57. This structure facilitates the addition of cleaning fluid to the liquid storage tank 5. A connecting plate 1 55 is fixedly connected to the middle of the lower surface of the inner wall of the liquid storage tank 5. A connecting plate 2 56 is fixedly connected to the left and right sides of the connecting plate 1 55. The connecting plate 1 55 and the connecting plate 2 56 are in a triangular block state. When the cleaning fluid soaked in the mold 2 flows into the inner cavity below the partition plate 53 through the pipe 54, it has a certain impact force after flowing out, which washes the concrete residue contained in the cleaning fluid into the two connecting plates 2 56 to accumulate and settle, which facilitates subsequent cleaning work. The setting of the connecting plate 1 55 also facilitates the discharge effect.
[0029] Working principle: In use, the steel reinforcement cage is first lifted by a crane, then placed directly above the mold 2, and slowly lowered. When the steel reinforcement cage is lowered to the appropriate position, the front and rear guide plates 4 contact the steel reinforcement cage. Then, the left and right motors 36 are started. Through the cooperation of gears 37 and racks 38, the T-shaped slider 33 moves upward and the hydraulic cylinder 34 is activated, so that the left and right hydraulic cylinders 34 and plates 35 clamp the steel reinforcement cage. Then, the motors 36 are turned off and the steel reinforcement cage is slowly lowered by the crane and enters the mold 2 to achieve a stable mold entry effect.
[0030] After use, the cleaning fluid in the storage tank 5 is drawn by the pump body 51 and the outlet pipe 52. The cleaning fluid is then soaked inside the mold 2 to facilitate the cleaning of residual concrete. After cleaning, the sealing rubber in the pipe 54 is pulled out so that the cleaning fluid flows into the storage tank 5 through the pipe 54 for easy collection.
[0031] The present invention has been described in detail above. However, modifications or improvements can be made to it, which will be obvious to those skilled in the art. Therefore, any modifications or improvements that do not depart from the spirit of the present invention are within the protection scope of the present invention.
