Description

Technical Field

[0001] This utility model relates to the field of trolley technology, and in particular to a trolley used for tunnel lining repair. Background Technology

[0002] As is well known, tunnels, as a key component of infrastructure such as transportation and water conservancy, are subjected to long-term pressure from surrounding rock, vehicle loads, and groundwater erosion, making their lining structures prone to defects such as cracks, spalling, and water leakage. If these defects are not repaired in time, they may lead to a decrease in the strength of the lining structure and even cause safety accidents such as collapse. Therefore, tunnel lining repair is a core link in ensuring the safe operation of tunnels.

[0003] However, traditional tunnel lining repair trolleys are usually fixed in height and width, making it difficult to adapt to tunnel cross-sections of different diameters. For defects in different locations such as the tunnel arch and sidewalls, it is necessary to frequently move equipment or build multiple platforms, resulting in low work efficiency.

[0004] Therefore, those skilled in the art have provided a trolley for tunnel lining repair to solve the problems mentioned in the background art. Utility Model Content

[0005] The purpose of this utility model is to address the shortcomings of existing technologies by proposing a trolley for tunnel lining repair. When in use, the trolley uses electric push rods on both sides of the mounting plate to drive the side frame to rotate around the top frame, which can flexibly adjust the angle of the side frame and the working range to adapt to the repair needs of different locations such as the tunnel arch and sidewalls. The servo motor in the mounting box at the lower end of the main frame drives the screw to rotate, which in turn drives the threaded sleeve plate and lifting rod to rise and fall, so that the bottom plate supports the ground. With the help of wear-resistant pads to enhance friction, the structural stability during operation is greatly improved.

[0006] To achieve the above objectives, the present invention provides the following technical solution: A trolley for tunnel lining repair includes a main frame. A crossbeam is fixedly connected to the upper and lower ends of the inner wall of the main frame. A mounting plate is fixedly connected to the upper end of the lower crossbeam. Multiple electric push rods are hinged to both sides of the outer wall of the mounting plate. The output ends of the multiple electric push rods on both sides are hinged to side frames. A mounting box is fixedly connected to the lower end of the main frame. Each mounting box has a storage cavity inside. A servo motor is fixedly connected to the center of the top surface of each storage cavity. A screw is fixedly connected to the output end of each servo motor. A threaded sleeve is fitted onto the outer wall of each screw. Lifting rods are fixedly connected to the four corners at the lower end of the threaded sleeve. The lower ends of the lifting rods penetrate the storage cavity to the outside of the mounting box and are fixedly connected to a base plate.

[0007] Compared with existing tunnel lining repair trolleys, this tunnel lining repair trolley uses electric push rods on both sides of the mounting plate to drive the side frame to rotate around the top frame. The angle of the side frame and the working range can be flexibly adjusted to adapt to the repair needs of different locations such as the tunnel arch and sidewalls. The servo motor in the mounting box at the lower end of the main frame drives the screw to rotate, which drives the threaded sleeve plate and lifting rod to rise and fall, so that the bottom plate supports the ground. With the help of wear-resistant pads to enhance friction, the structural stability during operation is greatly improved.

[0008] Furthermore, a top frame is fixedly connected to the upper end of the main frame; The above technical solution provides a stable rotation support point for the side frame through the top frame, while also enhancing the rigidity of the overall trolley structure.

[0009] Furthermore, the upper ends of the side frames are rotatably connected to both ends of the top frame; The above technical solution allows the side frame to rotate flexibly around the top frame, thereby enabling precise adjustment of the side frame's tilt angle to meet the repair needs of different parts of the tunnel.

[0010] Furthermore, each of the main frame components is fixedly connected to a movable wheel at its lower end near the outer wall of the mounting box; The above technical solution provides the trolley with convenient mobility through the movable wheels, enabling the trolley to be easily moved between different working areas within the tunnel.

[0011] Furthermore, each of the threaded sleeve plates is slidably connected to a smoke sensor located at the front end of the other side of the top surface of the load box, which is also slidably connected to the inner wall of the storage cavity. The above technical solution facilitates the movement of the lifting rod and the base plate through the threaded sleeve.

[0012] Furthermore, wear-resistant pads are fixedly connected to the lower end of each base plate; The above technical solution effectively enhances the friction between the base plate and the ground by using wear-resistant pads, preventing the trolley from slipping due to stress during operation.

[0013] This utility model has the following beneficial effects: 1. This utility model proposes a trolley for tunnel lining repair. Compared with existing tunnel lining repair trolleys, this trolley uses electric push rods on both sides of the mounting plate to drive the side frame to rotate around the top frame. The angle of the side frame and the working range can be flexibly adjusted to adapt to the repair needs of different locations such as the tunnel arch and sidewalls. The servo motor in the mounting box at the lower end of the main frame drives the screw to rotate, which drives the threaded sleeve plate and lifting rod to rise and fall, so that the bottom plate supports the ground. With the help of wear-resistant pads to enhance friction, the structural stability during operation is greatly improved. Attached Figure Description

[0018] Compared with existing tunnel lining repair trolleys, this tunnel lining repair trolley uses electric push rods 21 on both sides of the mounting plate 2 to push the side frame 14 to rotate around the top frame 11. The angle and working range of the side frame 14 can be flexibly adjusted to adapt to the repair needs of different locations such as the tunnel arch and sidewalls. The servo motor 24 in the mounting box 22 at the lower end of the main frame 1 drives the screw 25 to rotate, which drives the threaded sleeve plate 26 and the lifting rod 27 to rise and fall, so that the bottom plate 28 supports the ground. With the help of wear-resistant pads to enhance friction, the structural stability during operation is greatly improved.

[0019] A top frame 11 is fixedly connected to the upper end of the main frame 1; The top frame 11 provides a stable rotation support point for the side frame 14, while also enhancing the rigidity of the overall trolley structure.

[0020] The upper ends of the side frames 14 are rotatably connected to both ends of the top frame 11; The side frame 14 can rotate flexibly around the top frame 11, thereby enabling precise adjustment of the tilt angle of the side frame 14 to meet the repair needs of different parts of the tunnel, such as the arch and sidewalls.
