Description

Technical Field

[0001] This application relates to the field of tunnel construction technology, and in particular to a variable-diameter fully hydraulic concrete lining steel formwork trolley. Background Technology

[0002] Tunnel lining construction is a crucial step in tunnel construction, and the concrete lining steel formwork trolley is a key piece of equipment used for concrete lining in tunnel construction. It is mainly used for overall or partial concrete lining construction in tunnel engineering, and its core functions include formwork positioning, concrete support, and forming control. As tunnel engineering develops towards more complex geological conditions and larger cross-sections, the requirements for the adaptability of lining equipment are becoming increasingly stringent.

[0003] The diversity of actual engineering needs leads to variations in the dimensions of tunnel cross sections. Traditional concrete lining steel formwork trolleys adjust the diameter by adding or removing formwork segments. However, this segmented assembly adjustment method suffers from long construction interruptions and high labor costs. Therefore, an improvement has been made to a variable-diameter, fully hydraulic concrete lining steel formwork trolley. Utility Model Content

[0004] To address the shortcomings of existing technologies, this application provides a variable-diameter fully hydraulic concrete lining steel formwork trolley, which overcomes the deficiencies of existing technologies and aims to solve the problems of long construction interruption time and high labor costs associated with traditional concrete lining steel formwork trolleys that adjust diameter by adding or removing formwork segments.

[0005] To achieve the above objectives, this application provides the following technical solution: a variable-diameter fully hydraulic concrete lining steel formwork trolley, comprising a guide rail, a support frame above the guide rail, a lifting mechanism fixedly installed at the bottom of the support frame, a traveling mechanism fixedly installed at the bottom of the support frame outside the lifting mechanism, the support frame being slidably connected to the guide rail via the traveling mechanism, a vertical cylinder fixedly installed at the top of the support frame, a top template fixedly connected to the upper end of the vertical cylinder, side templates symmetrically arranged on both sides of the top template, and several mounting seats fixedly connected to the outer walls of both sides of the support frame, with lateral cylinders rotatably connected inside each of the mounting seats, the other end of each lateral cylinder being movably connected to the side template.

[0006] By adopting the above technical solution, the support frame is fixedly connected to the top template through a vertical hydraulic cylinder, and the side template is installed through the mounting base and the lateral hydraulic cylinder. That is, when facing tunnels of different sizes, the steel formwork trolley can adjust its height by driving the top template to move vertically up and down through the vertical hydraulic cylinder, and adjust its span by pushing the side template through the lateral hydraulic cylinder. This allows the steel formwork trolley to adapt to different tunnel cross-sectional dimensions without disassembling the template. The steel formwork trolley integrates a walking mechanism and a lifting mechanism through the support frame. The walking mechanism allows the steel formwork trolley to move freely, and the lifting mechanism allows for precise leveling.

[0007] As a preferred technical solution of this application, irrigation holes are provided through the outer surfaces of both the top template and the side template.

[0008] By adopting the above technical solution, the irrigation hole provides an irrigation path for the concrete irrigation pipe.

[0009] As a preferred technical solution of this application, the lifting mechanism includes a jack fixedly installed at the bottom of the support frame, a support block fixedly connected to the lower end of the jack, and a reinforcing block fixedly connected between the outer wall of the jack and the bottom of the support frame.

[0010] By adopting the above technical solution, the jack serves as the core lifting power source, driving the support block to move downwards and contact the guide rail, thereby lifting the support frame as a whole and achieving precise height adjustment of the steel mold trolley. The reinforcing block is used to strengthen the connection rigidity between the jack and the support frame, playing a role in reinforcement and support.

[0011] As a preferred technical solution of this application, the walking mechanism includes a drive box fixedly installed at the bottom of the support frame. Two rotating shafts are rotatably connected inside the drive box. A walking wheel is fixedly sleeved on the outer wall of each of the two rotating shafts. A transmission wheel is fixedly sleeved on the outer wall of the rotating shaft on one side of the walking wheel. A transmission belt is provided between the two transmission wheels. One end of one of the rotating shafts is fixedly connected to a transmission wheel two on the outside of the drive box. A transmission wheel three is provided above the transmission wheel two. A transmission belt two is provided between the transmission wheel three and the transmission wheel two. A drive motor for driving the transmission wheel three to rotate is provided above the drive box.

[0012] By adopting the above technical solution, the drive motor drives the transmission wheel three to rotate, and then the transmission effect between the transmission wheel three, the transmission wheel two and the transmission belt two is used to transmit the power to the rotating shaft that is fixedly connected to the transmission wheel two. The two rotating shafts are rigidly linked through the transmission wheel one and the transmission belt one, ensuring that the two traveling wheels rotate at the same speed and achieve synchronous rotation.

[0013] As a preferred technical solution of this application, a fixing seat is fixedly installed on the top of the drive box, and the top of the fixing seat is in contact with the bottom of the drive motor.

[0014] By adopting the above technical solution, the drive motor is limited and installed using a fixed base, which prevents the drive motor from shaking during operation and ensures the working stability of the drive motor.

[0015] As a preferred technical solution of this application, a protective cover is fixedly installed on the outer wall of the drive box by fixing screws, and the protective cover covers the transmission wheel three, transmission wheel two and transmission belt two inside it.

[0016] By adopting the above technical solution, the transmission wheel three, transmission wheel two, and transmission belt two are covered by a protective cover, which plays a role in isolation and protection.

[0017] As a preferred technical solution of this application, the front and rear outer walls of the support frame are symmetrically connected to a manned platform, and a staircase is fixedly connected to one side of the manned platform.

[0018] By adopting the above technical solution, it is easier for staff to climb onto the support frame.

[0019] Compared with the prior art, the beneficial effects of this utility model are as follows: In this invention, the support frame is fixedly connected to the top template via a vertical hydraulic cylinder, and the side template is installed via a mounting base and a lateral hydraulic cylinder. That is, when facing tunnels of different sizes, the steel formwork trolley can adjust its height by driving the top template vertically up and down via the vertical hydraulic cylinder, and adjust its span by pushing the side template via the lateral hydraulic cylinder. This allows the steel formwork trolley to adapt to different tunnel cross-sectional dimensions without disassembling the template. The steel formwork trolley integrates a walking mechanism and a lifting mechanism via the support frame, allowing the steel formwork trolley to move freely via the walking mechanism and to achieve precise leveling via the lifting mechanism.

[0024] like Figure 1 - Figure 4 As shown, this embodiment provides a variable-diameter fully hydraulic concrete lining steel formwork trolley, including a guide rail 1, a support frame 2 above the guide rail 1, a lifting mechanism 3 fixedly installed at the bottom of the support frame 2, and a traveling mechanism 4 fixedly installed at the bottom of the support frame 2 outside the lifting mechanism 3. The support frame 2 is slidably connected to the guide rail 1 through the traveling mechanism 4. A vertical cylinder 5 is fixedly installed at the top of the support frame 2, and a top template 6 is fixedly connected to the upper end of the vertical cylinder 5. Side templates 7 are symmetrically arranged on both sides of the top template 6. Several mounting seats 9 are fixedly connected to the outer walls of both sides of the support frame 2, and lateral cylinders 10 are rotatably connected inside the several mounting seats 9. The other end of the support frame 2 is movably connected to the side template 7. In use, the support frame 2 is fixedly connected to the top template 6 via the vertical cylinder 5. The side template 7 is installed via the mounting seat 9 and the side cylinder 10. That is, when facing tunnels of different sizes, the steel formwork trolley can adjust the height by driving the top template 6 vertically up and down via the vertical cylinder 5, and adjust the span by pushing the side template 7 via the side cylinder 10. This allows the steel formwork trolley to adapt to different tunnel cross-sectional dimensions without disassembling the template. The steel formwork trolley integrates the walking mechanism 4 and the lifting mechanism 3 via the support frame 2. The walking mechanism 4 enables the steel formwork trolley to move freely, and the lifting mechanism 3 enables precise leveling.

[0025] In this embodiment, as Figure 1 As shown, irrigation holes 8 are provided through the outer surfaces of the top formwork 6 and the side formwork 7. In use, the irrigation holes 8 provide an irrigation path for the concrete irrigation pipe.

[0026] In this embodiment, as Figure 2As shown, the lifting mechanism 3 includes a jack 31 fixedly installed at the bottom of the support frame 2. A support block 32 is fixedly connected to the lower end of the jack 31. A reinforcing block 33 is fixedly connected between the outer wall of the jack 31 and the bottom of the support frame 2. In use, the jack 31 serves as the core lifting power source, driving the support block 32 to move downward and contact the guide rail 1, thereby lifting the support frame 2 as a whole and achieving precise adjustment of the height of the steel mold trolley. The reinforcing block 33 is used to strengthen the connection rigidity between the jack 31 and the support frame 2, and plays a role in reinforcing the support.

[0027] In this embodiment, as Figure 1 , 3 As shown in Figure 4, the walking mechanism 4 includes a drive box 41 fixedly installed at the bottom of the support frame 2. Two rotating shafts 42 are rotatably connected inside the drive box 41. A walking wheel 43 is fixedly sleeved on the outer wall of each of the two rotating shafts 42. A transmission wheel 44 is fixedly sleeved on one side of the rotating shaft 42 near the walking wheel 43. A transmission belt 45 is provided between the two transmission wheels 44. One end of one of the rotating shafts 42 is fixedly connected to a transmission wheel 46 on the outside of the drive box 41. A transmission wheel 48 is positioned above the transmission wheel 46. The transmission wheel 48 and... A transmission belt 49 is provided between the two transmission wheels 46. A drive motor 47 is provided above the drive box 41 to drive the transmission wheel 48 to rotate. In use, the drive motor 47 drives the transmission wheel 48 to rotate. Then, the transmission effect between the transmission wheel 48, the two transmission wheels 46 and the transmission belt 49 is used to transmit power to the rotating shaft 42 which is fixedly connected to the transmission wheel 46. The two rotating shafts 42 are rigidly linked through the transmission wheel 44 and the transmission belt 45 to ensure that the two traveling wheels 43 rotate at the same speed and achieve synchronous rotation.

[0028] In this embodiment, as Figure 3 As shown, a mounting base 410 is fixedly installed on the top of the drive box 41. The top of the mounting base 410 fits against the bottom of the drive motor 47. During use, the mounting base 410 limits the installation of the drive motor 47 to prevent the drive motor 47 from shaking during operation and to ensure the working stability of the drive motor 47.

[0029] In this embodiment, as Figure 3 and 4 As shown, a protective cover 411 is fixedly installed on the outer wall of the drive box 41 by fixing screws. The protective cover 411 covers the transmission wheel 48, transmission wheel 46 and transmission belt 49 inside it. In use, the protective cover 411 covers the transmission wheel 48, transmission wheel 46 and transmission belt 49 to provide isolation and protection.

[0030] In this embodiment, as Figure 1As shown, the front and rear outer walls of the support frame 2 are symmetrically connected to the manned platform 11, and a staircase 12 is fixedly connected to one side of the manned platform 11, so that it is convenient for staff to climb onto the support frame 2 when in use.

[0031] The working principle of this utility model is as follows: When using the variable-diameter fully hydraulic concrete lining steel formwork trolley of this application, the walking mechanism 4 is started, and the drive motor 47 drives the transmission wheel 48 to rotate. Then, the transmission effect between the transmission wheel 48, the transmission wheel 46, and the transmission belt 49 is used to transmit power to the rotating shaft 42. The rotating shaft 42 drives the walking wheel 43 to rotate, and the steel formwork trolley is driven into the tunnel along the guide rail 1. After reaching the designated position, the lifting mechanism 3 is started, and the jack 31 drives the support block 32 to move downward and contact the guide rail 1, lifting the support frame 2 as a whole, so as to achieve precise height adjustment of the steel formwork trolley. Then, the vertical cylinder 5 is started to drive the top formwork 6 to move vertically up and down to adjust the height. The side cylinder 10 pushes the side formwork 7 to adjust the span, so as to adapt to the tunnel cross-section size and facilitate subsequent irrigation construction.
