Description

Technical Field

[0001] This invention belongs to the field of tunnel defect treatment technology, specifically relating to a displacement mechanism and method for equipment used in the structural inspection and repair of operating tunnels. Background Technology

[0002] In the field of railway tunnel inspection and repair, tunnel inspection platforms and tunnel defect treatment equipment are limited in function and cannot simultaneously offer the advantages of both mobile and fixed operation. Existing tunnel inspection equipment typically uses aerial work platforms with lifting columns fixed to railcars, lacking overall mobility and thus limiting their operational range, making them unsuitable for large-section double-track tunnels. Furthermore, tunnel defect treatment equipment still relies on manual on-site scaffolding to create a fixed work platform for workers to repair the entire tunnel section. This type of scaffolding is fixed, cannot be moved, and is time-consuming and labor-intensive, requiring dozens of workers 0.5-1 hour to complete. Designing and developing a rapid assembly mechanism for inspection / repair equipment that can adapt to the working conditions of operating railway tunnels would better meet future market demands. Summary of the Invention

[0003] The purpose of this invention is to provide a displacement mechanism for tunnel structure inspection and repair equipment, which enables the equipment mounted on it to change position within the tunnel, while taking into account the dual advantages of mobile and fixed operations. The mobile machinery has a large operating range and strong adaptability, while the fixed machinery has good stability.

[0004] The present invention adopts the following technical solution: a displacement mechanism for operating tunnel structure detection and repair equipment, comprising an upper module and a lower module arranged vertically, wherein the lower module can extend to its left or right outward to drive the upper module to move to its left or right outward;

[0005] The lower-level module includes: bottom connector, slide rail one, welded rail, slide rail assembly one, and slide rail assembly two, wherein:

[0006] The underlying connector is a horizontally arranged square frame;

[0007] The slide rail is a plurality of slide rails, each of which spans the left and right sides of the bottom connector. The plurality of slide rails are evenly spaced along the front and back direction of the bottom connector, and each slide rail is used to support the upper module.

[0008] The welding track spans the left and right sides of the bottom connector and is located near the front and rear ends, with two tracks at each end and spaced apart.

[0009] The slide rail assembly one and slide rail assembly two are located on the left and right sides of the bottom connecting member, and there are two of each. Each includes: slide rail legs, slide rails, rotary motors, and connecting plates, wherein:

[0010] The slide rail support leg is horizontally arranged, and its rear end is connected to the rotary motor. The rotary motor is used to drive the slide rail support leg to rotate with its rear end as a fixed point.

[0011] The slide rail is horizontally positioned within the welding track, with its left or right outer end connected to the top of the slide rail support leg.

[0012] Furthermore, a connecting plate is connected to the bottom outer end of the slide and along its entire length, and slide rail wheel sets are provided on the left and right sides of the connecting plate.

[0013] Furthermore, the connecting plate is connected to the driving device, which is a driving cylinder. Its piston rod is connected to the end of the connecting plate located at one end of the slide rail support leg through a plate body, and is used to drive the connecting plate to drive the slide rail to slide to the left or right outward.

[0014] Furthermore, in the middle of the bottom connector, and on its left and right sides, hydraulic motor one and hydraulic motor two are respectively provided to provide power for the upper module to move to the left and right.

[0015] Furthermore, there is one slide rail assembly one at the front and one at the back of the bottom connector, and at the same time, there is one slide rail assembly two at the front and one at the back of the bottom connector, which are arranged alternately with slide rail assembly one.

[0016] Furthermore, the upper module includes an upper connector, which is a horizontally arranged square frame structure and is the same size as the lower connector. Multiple crossbeams are arranged within the frame. On the lower wall of the crossbeam located in the middle of the upper connector, a rack is arranged through it along its left and right direction. The rack meshes with the gears of hydraulic motor one and hydraulic motor two.

[0017] Furthermore, multiple roller assemblies are provided on the left and right longitudinal beams of the upper connecting member, and on the lower wall of the longitudinal beams. The number of roller assemblies on one side of the longitudinal beam is the same as the number of slide rails. The distance between two adjacent roller assemblies on one side of the longitudinal beam is the same as the distance between two adjacent slide rails. Each roller assembly is used to roll within the corresponding slide rail.

[0018] Furthermore, roller assembly 2 and roller assembly 3 are respectively provided on the lower wall of the crossbeam corresponding to the positions of slide rail assembly 1 and slide rail assembly 2. Roller assembly 2 and roller assembly 3 are used to roll within slide rail assembly 1 and slide rail assembly 2.

[0019] Furthermore, horizontal hydraulic outrigger mounting plates are provided at both the front and rear ends near the upper connector, and the hydraulic outrigger mounting plates span the left and right longitudinal beams of the upper connector.

[0020] On each hydraulic outrigger mounting plate, there is a vertically downward, retractable hydraulic outrigger located on both the left and right sides;

[0021] Each of the hydraulic outrigger mounting plates has a mounting base located at its left and right edges.

[0022] This invention also discloses a displacement method for the displacement mechanism of the above-mentioned equipment for structural inspection and repair of operating tunnels, the displacement method being as follows:

[0023] When the displacement mechanism is located on the left line of the tunnel, the drive cylinder pushes the connecting plate, and the slide rail wheel assembly slides to the right and outward along the welded track, simultaneously driving the slide rail and slide rail support leg to slide outward to the right until it reaches the set position; the slide rail support leg rotates from horizontal to vertical under the action of the rotary motor and extends until its bottom end contacts the bottom surface of the tunnel; at the same time, the upper connecting member, driven by the hydraulic motor and rack, drives the roller assembly one, roller assembly two, and roller assembly three (4c) to slide to the right in the slide rail one, slide rail assembly one, and slide rail assembly two respectively until they reach the set position, and the hydraulic support leg extends downward and contacts the bottom surface of the tunnel; when the operation is completed, the upper connecting member slides to the left in the opposite direction until it is located on the lower connecting member; the slide rail assembly one slides to the left in the opposite direction until it returns to its original position;

[0024] When the displacement mechanism is located on the right line of the tunnel, the same operation as on the left line is used to slide the bottom connector to the left, thereby driving the upper module to slide to the left; and after the operation is completed, it slides to the right to reset.

[0025] The beneficial effects of this invention are: 1. By separating the positioning mechanism from the traditional equipment body and designing it independently, it provides a sliding rail that can move in both directions, allowing it to quickly move to the left or right work point according to site requirements. This optimizes the workflow and expands the work area. 2. The modular design of the positioning mechanism allows for the mounting and assembly of various testing / repair equipment. The corner fittings around the positioning mechanism enable rapid hoisting and locking connections with semi-trailers / rail flatbed trucks, making transportation extremely convenient.

[0032] The present invention will now be described in detail with reference to the accompanying drawings and specific embodiments.

[0033] The present invention provides a displacement mechanism for operating tunnel structure inspection and repair equipment. Its length is the same as that of a 20-foot / 40-foot container, which can be quickly hoisted. By engaging and locking the corner fittings on the four sides with the mushroom heads on the rail flatcar / semi-trailer, the tunnel structure inspection and repair equipment can be assembled and fixed on the mounting base 4f, forming an organic whole with the displacement mechanism for overall transportation.

[0034] This invention discloses a displacement mechanism for equipment used in the inspection and repair of tunnel structures, such as... Figure 1 As shown, it includes an upper module 4 and a lower module 3 arranged vertically. The lower module 3 can extend to its left or right outwards to drive the upper module 4 to move to its left or right outwards.

[0035] like Figure 2 and 4 As shown, the lower module 3 includes: a bottom connector 3f, a slide rail 3a, a welding rail 3f1, a slide rail assembly 3b, and a slide rail assembly 3c, wherein:

[0036] The bottom connector 3f is a horizontally set square frame;

[0037] There are multiple slide rails 3a, each of which spans the left and right sides of the bottom connector 3f. The multiple slide rails 3a are evenly spaced along the front and back direction of the bottom connector 3f, and each slide rail 3a is used to support the upper module 4.

[0038] Welding track 3f1 spans the left and right sides of the bottom connector 3f and is located near the front and rear ends, with two at each end and two spaced apart.

[0039] Slide rail assembly 1 (3b) and slide rail assembly 2 (3c) are located on the left and right sides of the bottom connector (3f), and there are two of each. Each assembly includes: slide rail support leg (3b1), slide rail (3b6), rotary motor (3b2), and connecting plate (3b5), wherein:

[0040] The slide rail support leg 3b1 is horizontally positioned, and its rear end is connected to the rotary motor 3b2. The rotary motor 3b2 is used to drive the slide rail support leg 3b1 to rotate with its rear end as a fixed point.

[0041] The slide rail 3b6 is horizontally set inside the welding rail 3f1, and its left or right outer end is connected to the top of the slide rail support leg 3b1.

[0042] A connecting plate 3b5 is connected to the bottom outer end of the slide 3b6 along its entire length, and slide rail wheel sets 3b3 are provided on the left and right sides of the connecting plate 3b5.

[0043] The connecting plate 3b5 is connected to the driving device, which is a driving cylinder 3b4. Its piston rod is connected to the end of the connecting plate 3b5 located at one end of the slide rail support leg 3b1 through a plate body, and is used to drive the connecting plate 3b5 to drive the slide rail 3b6 to slide to the left or right.

[0044] In the middle of the bottom connector 3f, and on its left and right sides, there are hydraulic motor 3d and hydraulic motor 3e respectively. Hydraulic motor 3d and hydraulic motor 3e are used to provide power for the upper module 4 to move to the left and right.

[0045] There is one slide rail assembly 3b at the front and one at the back along the bottom connector 3f. At the same time, there is one slide rail assembly 3c at the front and one at the back along the bottom connector 3f, and they are arranged alternately with slide rail assembly 3b.

[0046] like Figure 3 As shown, the upper module 4 includes an upper connector 4d, which is a horizontally arranged square frame structure and is the same size as the lower connector 3f. Multiple crossbeams are arranged inside the frame. On the lower wall of the crossbeam located in the middle of the upper connector 4d, a rack is arranged through it along its left and right direction. The rack is welded to the lower wall of the middle crossbeam and meshes with the gears of the hydraulic motor 3d and the hydraulic motor 3e.

[0047] Multiple roller assemblies 4a are installed on the left and right longitudinal beams of the upper connecting member 4d, and on the lower wall of the longitudinal beams. The number of roller assemblies 4a on one side of the longitudinal beam is the same as the number of slide rails 3a. The spacing between two adjacent roller assemblies 4a on one side of the longitudinal beam is the same as the spacing between two adjacent slide rails 3a. Each roller assembly 4a is installed in the corresponding slide rail 3a.

[0048] On the lower wall of the crossbeam corresponding to the positions of slide rail assembly 3b and slide rail assembly 3c, roller assembly 4b and roller assembly 4c are respectively provided. Roller assembly 4b and roller assembly 4c are used to slide within slide rail assembly 3b and slide rail assembly 3c.

[0049] A horizontal hydraulic outrigger mounting plate is provided at both the front and rear ends near the upper connector 4d. The hydraulic outrigger mounting plate spans the left and right longitudinal beams of the upper connector 4d. A vertically downward and retractable hydraulic outrigger 4e is welded to each hydraulic outrigger mounting plate on both the left and right sides. A mounting seat 4f is provided on each hydraulic outrigger mounting plate at its left and right edges.

[0050] The aforementioned upper connecting member 4d includes two longitudinal beams spaced apart on the left and right, with multiple transverse beams connecting the two longitudinal beams. The transverse beams are spaced apart along the length of the longitudinal beams, and the longitudinal beams and transverse beams are welded together to form a square frame. At the front and rear ends of the frame, and between the two transverse beams at the ends, multiple short longitudinal beams are connected to reinforce the square frame.

[0051] The displacement method of the displacement mechanism for the above-mentioned tunnel structure inspection and repair equipment is as follows: After transporting it to the location in tunnel 1 that needs inspection / repair via a rail flatcar 2, if the railcar is at this time... Figure 1At the left-hand position, under the action of the drive cylinder 3b4, the connecting plate 3b5 is pushed, and the slide rail wheel assembly 3b3 slides to the right and outward along the welding track 3f1. Simultaneously, the slide rail 3b6 and the slide rail support leg 3b1 slide outward to the right. The left-right length of the slide rail 3b6 can be set to 2.5m, but other distances are possible as needed. Subsequently, under the action of the rotary motor 3b2, the slide rail support leg 3b1 rotates 90° from a horizontal position to a vertical position and gradually extends until the bottom of the slide rail support leg 3b1 contacts the tunnel floor. A pressure sensor is installed on the slide rail support leg 3b1; when the sensor signal indicates pressure, it means that the slide rail support leg 3b1 has extended to its full position. At this point, driven by the hydraulic motor 3e and rack 4d4, the upper module 4 and the assembled testing and repair equipment move smoothly 2.5m to the right within the slide rail 3b6 of slide rail 3a, slide rail 3b, and slide rail 3c, respectively. Other distances may be used as needed. Once in position, the hydraulic outrigger 4e quickly extends and contacts the tunnel floor, working together with the slide rail 3b to support the entire upper module 4 and the assembled testing and repair equipment. A pressure sensor is installed on the hydraulic outrigger 4e; when the sensor signal indicates pressure, it means the hydraulic outrigger 4e has extended to its designated position. This completes one long-distance tunnel repositioning of the testing and repair equipment. When the operation is finished, all equipment and mechanisms can be restored to their initial transport state by reversing the sequence of actions.

[0052] When the railcar is Figure 1 When the slide rail assembly is in the right position, simply extend slide rail assembly 2 3c to the left. Slide rail assembly 2 3c and slide rail assembly 1 3b are structurally identical, and their subsequent actions are exactly the same, only in opposite directions. After slide rail assembly 2 3c is in position, the upper module 4 and the detection and repair equipment assembled on it move to the left under the drive mechanism composed of hydraulic motor 1 3d and rack 4d4. Hydraulic motor 1 3d and hydraulic motor 2 3e are completely identical, sharing the same rack 4d4, and their functions and subsequent actions are exactly the same, only in opposite directions.
