[0001] The invention relates to the technical field of tunnel engineering, in particular to a multifunctional shield tunnel repair vehicle. Background Art

[0002] The tunnel repair vehicle is a special vehicle used for tunnel repair and maintenance work. It includes a cab and a bracket connected to the rear end. The bracket is provided with a working platform. The working platform includes a main chassis, a steel structure installation mechanism and a climbing working mechanism.

[0003] When the tunnel repair vehicle is in use, it is necessary to drive the working platform to rise and fall to process different positions in the tunnel. The working platform is prone to shaking during the lifting and lowering, which affects the lifting and lowering stability of the working platform. At the same time, the working platform cannot always remain level during the lifting and lowering process. It is difficult for construction workers to maintain balance on an uneven work frame, and they are prone to slipping and falling, which is dangerous. Summary of the invention

[0004] The object of the present invention is to provide a multifunctional shield tunnel repair vehicle to solve the problems raised in the above-mentioned background technology.

[0005] To achieve the above-mentioned purpose, the present invention provides the following technical solutions: a multifunctional shield tunnel repair vehicle, comprising a repair vehicle body, a positioning guide rail is fixedly installed at the top center position of the repair vehicle body, two annular guide frames are horizontally mounted on the repair vehicle body, an annular limiting groove along the circumferential direction is opened on the annular guide frame, a frame composed of an arc-shaped assembly plate and a connecting assembly plate is movably sleeved on the annular guide frame, an arc-shaped positioning rod located in the annular limiting groove is fixedly installed on the inner wall of the connecting assembly plate, a rotating shaft is rotatably connected to the connecting assembly plate, and a The rotating plate is fixedly connected, a working frame is fixedly installed on the top of the rotating plate, an assembly base is vertically fixedly installed at the bottom center position of the rotating plate, a telescopic rod is horizontally slidably connected in the positioning guide rail, the piston rod of the telescopic rod is fixedly installed on the bottom of the assembly base, a sliding base is coaxially fixedly installed on the bottom of the telescopic rod, a positioning side groove is opened on the outer wall of the sliding base, and limiting strips corresponding to the positioning side grooves are arranged on both sides of the inner wall of the positioning guide rail, a driving assembly is fixedly installed on the arc-shaped assembly plate, and a gear meshing with the annular guide frame is arranged on the driving assembly.

[0006] Preferably, both ends of the positioning guide rail are provided with limiting end plates.

[0007] Preferably, a positioning rotating ball is rotatably connected to the bottom of the sliding base, a semicircular long groove is provided at the bottom of the inner wall of the positioning guide rail, the positioning rotating ball is located in the semicircular long groove, and the positioning rotating ball is slidably connected to the semicircular long groove.

[0008] Preferably, the rotating plate and the assembly base form a cross mounting frame.

[0009] Preferably, assembly frames are fixedly installed on both sides of the repair vehicle body, side accessory mounting plates are fixedly installed on both sides of the assembly frame, a vertical lifting column is vertically slidably connected in the assembly frame, an assembly top plate is fixedly installed on the top of the assembly top plate, and a counterweight placement rack is fixedly installed on the top of the assembly top plate.

[0010] Preferably, a mounting base plate is fixedly mounted on the bottom end of the vertical lifting column, and a non-slip base plate is fixedly mounted on the bottom of the mounting base plate.

[0011] Preferably, a screw rod is threadedly connected to the side accessory mounting plate, and the top end of the screw rod is supported at a position corresponding to the bottom of the assembly top plate.

[0012] Preferably, an assembly frame is movable sleeved on the connection assembly plate, an instrument mounting frame is fixedly mounted on the outer side of the assembly frame, and the assembly frame is fixedly mounted on the connection assembly plate by bolts.

[0013] Preferably, the assembly frame and the instrument mounting frame are an integrally formed structure.

[0014] Preferably, the assembly frame and the instrument mounting frame are arranged along a radial direction corresponding to the annular guide frame.

[0015] Compared with the prior art, the present invention has the following beneficial effects: 1. Install different components between the connecting assembly plates according to the repair needs. When more difficult repairs are required, workers are required to make detailed modifications to specific locations. When the work frame is at a lower position, workers stand at the corresponding position on the work frame, and drive the arc-shaped assembly plate and the connecting assembly plate structure up and down through the driving component to drive the rotating plate and the work frame structure to move upward. After the work frame moves to the appropriate position and height, the driving component stops working, and the arc-shaped assembly plate and the connecting assembly plate structure no longer move, thereby achieving the adjustment and fixation of the position of the work frame and the assembly base. Construction workers work on a horizontal work frame without having to worry about accidents such as slips and falls caused by the tilt of the work frame, providing them with a stable and reliable working environment. In a horizontal state, tools, materials and other items placed on the work frame are not easy to slide, avoiding damage to personnel and equipment below caused by falling items.

[0016] 2. When a relatively simple repair is required, the rotating shaft, rotating plate, and working frame structure are disassembled, and then the assembly frame and instrument mounting frame structure are installed between the connecting assembly plates. The instrument mounting frame installation and repair tool is moved through the arc-shaped assembly plate and the connecting assembly plate structure to achieve the change of the position of the assembly frame and the instrument mounting frame, which is suitable for relatively simple repairs.

[0017] 3. When the repair vehicle body reaches the position that needs to be repaired, it is necessary to stop the repair vehicle body to ensure stability during the repair process. By twisting the screw rod, the assembly base plate and the anti-slip base plate structure are driven to descend and rise, so as to achieve the fixation of the repair vehicle body after stopping.

[0028] In order to make the purpose, technical solution and advantages of the present invention clearer, the technical solution in the embodiment of the present invention will be clearly and completely described below in conjunction with the drawings in the embodiment of the present invention. Obviously, the described embodiment is a part of the embodiment of the present invention, not all the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0029] See also Figures 1 to 9The present invention provides a technical solution: a multifunctional shield tunnel repair vehicle, comprising a repair vehicle body 1, the repair vehicle body 1 is a trolley, and slides on a track corresponding to the bottom of the inner wall of the tunnel, and a pulley is arranged at the bottom of the repair vehicle body 1 for sliding the repair vehicle body 1 and the track in the tunnel, a positioning guide rail 2 is fixedly installed at the center position of the top of the repair vehicle body 1, and a corresponding groove is arranged in the positioning guide rail 2 for sliding the corresponding structure, so as to ensure that the telescopic rod 11 moves accordingly during the movement of the working frame 9, and two annular guide frames 3 are horizontally arranged on the repair vehicle body 1, and the annular guide frame 3 is a circular ring structure, and the part of the annular guide frame 3 corresponding to the repair vehicle body 1 is cut off, and the annular guide frame 3 is concentric with the tunnel to ensure that the working frame After 9 moves to the corresponding position, the working frame 9 corresponds to the position of the tunnel, and the annular guide frame 3 is provided with an annular limiting groove 301 along the circumferential direction, and the annular limiting groove 301 is arranged in the radial direction on both sides of the annular guide frame 3. The annular guide frame 3 is movably sleeved with a frame composed of an arc-shaped assembly plate 4 and a connecting assembly plate 5. The arc-shaped assembly plate 4 is an arc corresponding to the shape of the annular guide frame 3, and the arc angle corresponding to the arc-shaped assembly plate 4 is consistent with the angle of the annular guide frame 3. The two arc-shaped assembly plates 4 form a structure parallel to the annular guide frame 3. At the same time, the arc-shaped assembly plate 4 and the connecting assembly plate 5 form a frame structure corresponding to the shape of the annular guide frame 3, thereby ensuring that the structure composed of the arc-shaped assembly plate 4 and the connecting assembly plate 5 moves on the annular guide frame 3 and is moved by the arc positioning rod 6. The movement in the annular limit groove 301 ensures the stability of the arc-shaped assembly plate 4 and the connecting assembly plate 5 during the movement. An arc-shaped positioning rod 6 located in the annular limit groove 301 is fixedly installed on the inner wall of the connecting assembly plate 5. A rotating shaft 7 is rotatably connected to the connecting assembly plate 5. The relative rotation between the rotating shaft 7 and the arc-shaped assembly plate 4 ensures that when the arc-shaped assembly plate 4 and the connecting assembly plate 5 form a structure that moves, the rotating plate 8 will rotate around the rotating shaft 7, thereby ensuring that the working frame 9 is always in a vertical state, so that the staff can always work in a vertical state. The movement of the working frame 9 on the annular guide frame 3 ensures that the staff can perform maintenance and processing on the inner wall of the tunnel at different heights. A rotating plate 8 is set between the two rotating shafts 7 for fixing. The rotating plate 8 is connected, and grooves corresponding to the shape of the rotating shaft 7 are provided at both ends of the rotating plate 8 to ensure the rotation of the rotating plate 8 around the rotating shaft 7, so as to realize the rotating connection structure composed of the rotating shaft 7 and the rotating plate 8. A working frame 9 is fixedly installed on the top of the rotating plate 8, and an assembly base 10 is vertically fixedly installed at the bottom center of the rotating plate 8. The rotating plate 8 and the assembly base 10 form a cross mounting frame, and the assembly base 10 is fixedly installed at the bottom of the rotating plate 8, and the rotating plate 8 and the assembly base 10 form a cross-shaped frame, and the assembly base 10 is horizontally arranged, and a telescopic rod 11 is horizontally slidably connected in the positioning guide rail 2, and the piston rod of the telescopic rod 11 is fixedly installed at the bottom of the assembly base 10, and the piston rod of the assembly base 10 is vertically lifted and lowered to adapt to the lifting height of the assembly base 10.At the same time, the sliding base 12 at the bottom of the telescopic rod 11 will move on the positioning guide rail 2 to adapt to the lateral position of the working frame 9 on the annular guide frame 3. The bottom of the telescopic rod 11 is coaxially fixed with a sliding base 12. A positioning side groove 1201 is provided on the outer wall of the sliding base 12. The sliding base 12 slides on the limit bar 201 to ensure the sliding stability of the sliding base 12. Limit bars 201 corresponding to the positioning side grooves 1201 are provided on both sides of the inner wall of the positioning guide rail 2. A driving component 13 is fixedly installed on the arc assembly plate 4. The driving component 13 is provided with a gear meshing with the annular guide frame 3. The driving component 13 is a driving device. The driving component 13 is driven by a motor, a transmission gear box and a gear driven by the transmission gear box. Through the meshing of the gear with the annular guide frame 3, the structure composed of the arc assembly plate 4 and the connecting assembly plate 5 is reversely driven to move, thereby driving the corresponding structure to move.

[0030] Limiting end plates 14 are provided at both ends of the positioning guide rail 2 , and the limiting end plates 14 limit the movement of the sliding base 12 , thereby ensuring that the sliding base 12 will not fall off the positioning guide rail 2 .

[0031] The bottom of the sliding base 12 is rotatably connected to a positioning rotating ball 15, and a semicircular long groove 16 is provided at the bottom of the inner wall of the positioning guide rail 2. The positioning rotating ball 15 is located in the semicircular long groove 16, and the positioning rotating ball 15 is slidably connected to the semicircular long groove 16. By sliding the positioning rotating ball 15 in the semicircular long groove 16, the sliding resistance of the sliding base 12 in the positioning guide rail 2 is reduced, thereby improving the smoothness of movement of the structure composed of the telescopic rod 11 and the sliding base 12.

[0032] An assembly frame 17 is fixedly installed on both sides of the repair vehicle body 1, and side accessory mounting plates 18 are fixedly installed on both sides of the assembly frame 17. A vertical lifting column 19 is vertically slidably connected in the assembly frame 17, and an assembly top plate 20 is fixedly installed on the top of the vertical lifting column 19. A counterweight placement rack 21 is fixedly installed on the top of the assembly top plate 20. The vertical lifting column 19 moves up and down in the assembly frame 17, thereby driving the lower end of the vertical lifting column 19 to move. A corresponding groove is provided on the top of the counterweight placement rack 21, so that the weight of the counterweight placement rack 21 can be selected.

[0033] An assembly base plate 22 is fixedly installed at the bottom end of the vertical lifting column 19, and an anti-skid base plate 23 is fixedly installed at the bottom of the assembly base plate 22. The assembly base plate 22 and the anti-skid base plate 23 form a structure for the tunnel ground, thereby ensuring that after the repair vehicle body 1 moves to the specified position, the assembly base plate 22 and the anti-skid base plate 23 have a fixing effect on the repair vehicle body 1.

[0034] A screw rod 24 is threadedly connected to the side accessory mounting plate 18, and the top end of the screw rod 24 is supported at a position corresponding to the bottom of the assembly top plate 20. Through the rotation of the screw rod 24, the assembly top plate 20 and the counterweight placement frame 21 are driven to rise and fall, thereby driving the vertical lifting column 19 to rise and fall in the assembly frame 17, thereby realizing the lifting and lowering of the assembly bottom plate 22 and the anti-slip bottom plate 23.

[0035] An assembly frame 25 is provided on the connecting assembly plate 5 in a movable sleeve, and an instrument mounting frame 26 is fixedly installed on the outer side of the assembly frame 25, and the assembly frame 25 is fixedly installed on the connecting assembly plate 5 by bolts. The assembly frame 25 and the instrument mounting frame 26 can be assembled on the connecting assembly plate 5 according to selection. After the rotating shaft 7, the rotating plate 8, and the working frame 9 are disassembled, the assembly frame 25 and the instrument mounting frame 26 are installed on the connecting assembly plate 5. The assembly frame 25 is a frame structure, which is used to ensure that the assembly frame 25 and the connecting assembly plate 5 are assembled by bolts.

[0036] The assembly frame 25 and the instrument mounting frame 26 are an integrally formed structure, which improves the convenience of manufacturing the structure composed of the assembly frame 25 and the instrument mounting frame 26.

[0037] The assembly frame 25 and the instrument mounting frame 26 are arranged along the radial direction corresponding to the annular guide frame 3, ensuring that the repair structure installed on the instrument mounting frame 26 can be perpendicular to the tunnel surface, ensuring better repair.

[0038] Working principle: Step 1: Install different components between the connecting assembly plates 5 according to the repair needs. When a more difficult repair is required, workers are required to make detailed modifications to the specific positions. When the work frame 9 is at a lower position, the worker stands at the corresponding position on the work frame 9 and drives the corresponding gear to rotate through the driving component 13. Through the meshing of the gear and the teeth on the annular guide frame 3, the structure composed of the arc-shaped assembly plate 4 and the connecting assembly plate 5 is driven to move on the annular guide frame 3, driving the work frame 9 to a suitable height to ensure that the workers can work better. When the structure composed of the arc-shaped assembly plate 4 and the connecting assembly plate 5 is lifted or lowered, the structure composed of the rotating plate 8 and the work frame 9 is driven to move upward, and the rotating plate 8 and the work frame 9 are driven upward. When the structure composed of the plate 8 and the assembly base 10 moves upward, the piston rod of the telescopic rod 11 extends out to adapt to the rise of the structure composed of the rotating plate 8 and the assembly base 10. At the same time, the sliding base 12 at the bottom of the telescopic rod 11 will also slide in the positioning guide rail 2. When the sliding base 12 slides in the positioning guide rail 2, the positioning rotating ball 15 at the bottom of the sliding base 12 will slide in the semicircular long groove 16, and the limit bar 201 will also slide in the positioning side groove 1201. After the working frame 9 moves to a suitable position and height, the driving component 13 stops working, and the structure composed of the arc-shaped assembly plate 4 and the connecting assembly plate 5 no longer moves, thereby realizing the adjustment and fixation of the position of the working frame 9 and the assembly base 10.

[0039] Step 2: When a relatively simple repair is required, the structure composed of the rotating shaft 7, the rotating plate 8, and the working frame 9 is disassembled, and then the structure composed of the assembly frame 25 and the instrument mounting frame 26 is installed between the connecting assembly plates 5. After the assembly frame 25 is installed, the connection between the connecting assembly plate 5 and the assembly frame 25 is fixed by bolts, and the instrument mounting frame 26 is installed with a repair tool, and the position of the assembly frame 25 and the instrument mounting frame 26 is changed by moving the structure composed of the arc-shaped assembly plate 4 and the connecting assembly plate 5, so as to adapt to relatively simple repairs.

[0040] Step 3: When the repair vehicle body 1 reaches the position that needs to be repaired, the repair vehicle body 1 needs to be stopped to ensure stability during the repair process. By twisting the screw rod 24, the assembly frame 25 is threadedly moved on 28, so that the top of the screw rod 24 drops, and the assembly top plate 20 and the counterweight placement frame 21 form a structure that moves downward, thereby driving the vertical lifting column 19 to descend in the assembly frame 17, ensuring the descent of the assembly bottom plate 22 and the anti-skid bottom plate 23. After the assembly bottom plate 22 and the anti-skid bottom plate 23 form a structure that descends, the anti-skid bottom plate 23 contacts the tunnel ground, and the weight of the counterweight placement frame 21 is used to fix the repair vehicle body 1 after it stops. Rotating the screw rod 24 drives the counterweight placement frame 21 and the assembly top plate 20 to move upward, so that the repair vehicle body 1 can continue to move.
