Description

Technical Field

[0001] This invention relates to the field of wall cutting, and in particular to a device for cutting visible seams in subway side walls. Background Technology

[0002] With the continuous progress of society, more and more subways are being built to meet people's travel needs. The side walls of the subway are an important part of the subway tracks, and during the construction of the side walls, it is necessary to cut open seams on the surface for the installation of pipelines, etc.

[0003] Currently, cutting visible seams in subway side walls involves manually gripping a cutting machine to cut the side wall, which is inefficient. Alternatively, the cutting machine can be mounted on a liftable frame and moved to complete the cut, but this method can only cut side walls over a certain distance and cannot meet the needs of more construction scenarios. Summary of the Invention

[0004] To meet the needs of cutting operations in more construction scenarios, this application provides a subway side wall open joint cutting device.

[0005] This application provides a subway sidewall surface joint cutting device, which adopts the following technical solution:

[0006] A subway side wall surface joint cutting device includes a traveling vehicle, a lifting module mounted on the traveling vehicle, a mounting frame mounted on the lifting platform of the lifting module, an adjusting frame mounted on the mounting frame, and a cutting machine mounted at one end of the adjusting frame. The end of the adjusting frame away from the cutting machine is hinged to the mounting frame, and the mounting frame is equipped with an adjusting component for adjusting the rotational position of the adjusting frame. The bottom end of the lifting module is hinged to the traveling vehicle, and the traveling vehicle is equipped with a first driving component for driving the lifting module to rotate.

[0007] By adopting the above technical solution, when cutting is required, the traveling vehicle moves to the position to be cut, and then, according to the shape of the side wall, the angle of the lifting module is adjusted by the first drive component, and the rotation angle of the adjusting frame is adjusted by the adjusting component, so that the cutting direction of the cutting machine corresponds to the side wall; then the cutting machine is started, and the movement of the traveling vehicle and the lifting module drive the mounting frame to move, thereby driving the cutting machine to cut along the height direction of the side wall; the above structure can adjust the position of the cutting machine according to the angle of the side wall, which can meet the cutting construction in more construction scenarios; and the use of automated cutting improves the overall cutting efficiency.

[0008] Preferably, the adjusting assembly includes an adjusting screw, connecting rods, and sliding blocks. The adjusting screw has threads with opposite helical directions at both ends and is rotatably mounted on the mounting frame. The sliding blocks are slidably mounted on the adjusting frame along its length. Moving blocks are threaded onto both ends of the opposite threads of the adjusting screw. A pair of connecting rods are provided, with one end of each connecting rod hinged to one of the moving blocks and the other end of each connecting rod simultaneously hinged to the sliding blocks. The adjusting assembly also includes a second driving member for driving the adjusting screw to rotate.

[0009] By adopting the above technical solution, when the vehicle travels close to the side wall but cannot travel to a point where the cutting machine can directly cut the side wall due to the construction environment; and when the cutting plane of the side wall has a certain tilt angle; the second driving component can drive the adjusting screw to rotate, thereby driving the two connecting rods connected to the adjusting screw to move in opposite directions, thus driving the adjusting frame to rotate, thereby adjusting the cutting position or cutting angle of the cutting machine; in addition, the adjustment by adjusting the screw is more precise than other adjustment methods.

[0010] Preferably, the adjusting frame is equipped with an arc-shaped protective cover corresponding to the cutting machine. The arc-shaped protective cover has an arc-shaped groove inside, which extends along the arc direction of the arc-shaped protective cover. The arc-shaped protective cover is slidably installed in the arc-shaped groove. An opening is provided at one end of the top of the arc-shaped protective cover for the arc-shaped protective cover to slide out. The adjusting frame is equipped with a first driving component for driving the arc-shaped protective cover to slide.

[0011] By adopting the above technical solution, the arc-shaped protective cover can not only block the splashing of cutting fluid and debris, but also serve as a cutting guide. After the cutting is completed, the arc-shaped protective cover is driven out of the arc-shaped groove by the first driving component to cover the partially exposed cutting blade, reducing the risk of damage from contact with other objects or injury to personnel from contact with people.

[0012] Preferably, the first driving assembly includes a driving rack and a first elastic element. A sliding groove extending along the length of the adjusting frame is provided within the adjusting frame and on one side of the outer arc surface of the arc-shaped protective cover. The sliding groove extends beyond the top of the adjusting frame, and the driving rack is slidably mounted within the sliding groove. A connecting hole is provided on the side of the arc-shaped protective cover near the sliding groove, and the connecting hole connects to the sliding groove. The outer arc surface of the arc-shaped protective cover is provided with teeth, and the driving rack meshes with the teeth. The first elastic element is installed between the driving rack and the bottom end of the sliding groove. When the first elastic element is in a compressed state, the arc-shaped protective cover is located within the arc-shaped groove, and the top end of the driving rack is located at the top of the sliding groove. A limiting component for restricting the first elastic element from being in a compressed state is installed within the adjusting frame.

[0013] By adopting the above technical solution, after cutting, the constraint on the first elastic element is released by the limiting component. The elasticity of the first elastic element pushes the drive rack to slide. The drive rack can then drive the arc-shaped cover to slide out of the arc-shaped protective cover by cooperating with the tooth pattern, and the top of the drive rack extends out of the sliding groove. By pressing the drive rack that extends out of the sliding groove, the arc-shaped cover can be driven to slide in the opposite direction until the arc-shaped cover retracts into the arc-shaped protective cover. Finally, the driving rack is limited by the limiting component. This process drives the arc-shaped cover to slide with high stability and is easy to operate.

[0014] Preferably, the limiting component includes a locking rod and a third driving member. The adjusting frame has a moving groove communicating with the sliding groove. The moving groove extends in a direction perpendicular to the sliding groove. The locking rod is slidably installed in the moving groove. The locking rod has a through hole corresponding to the position of the driving rack for the driving rack to pass through. The side wall of the driving rack has a locking groove for the hole wall of the through hole to be engaged. The third driving member is used to drive the locking rod to slide.

[0015] By adopting the above technical solution, when it is necessary to loosen the restraint on the first elastic element, the third driving element drives the locking rod to slide until the hole wall of the perforation leaves the locking groove, thus completing the unlocking. This structure is simple and the locking position is stable.

[0016] Preferably, the third driving component includes a second elastic element and a push rod. The second elastic element is installed at the bottom of the locking rod and the moving groove. The moving groove is located at a position corresponding to the connecting rod, and one end of the moving groove near the connecting rod extends out of the adjusting frame. The locking groove is located on the side of the driving rack away from the connecting rod. When the second elastic element is in its natural state, the wall of the through hole is engaged in the locking groove. The push rod is installed on the connecting rod and at a position corresponding to the moving groove.

[0017] By adopting the above technical solution, after cutting, the adjusting screw drives one end of the two connecting rods connected to the adjusting screw to move away from each other, which drives the adjusting frame to rotate towards the mounting frame. At this time, the pushing rod can extend into the moving groove and push the locking rod, so that the hole wall of the perforation leaves the locking groove, thus unlocking. When the driving rack is pressed, the driving connecting rod changes, causing the pushing rod to leave the moving groove. At the same time, the second elastic element drives the locking rod to reset, causing the hole wall of the perforation to lock into the locking groove. The above process does not require an additional power source, reducing costs and achieving high synchronization.

[0018] Preferably, the first driving component is a cylinder, the cylinder is inclined, the cylinder is hinged to the vehicle, and the piston rod of the cylinder is hinged to the lifting module.

[0019] By adopting the above technical solution, the angle of the lifting module can be adjusted, thereby adjusting the cutting angle of the cutting machine.

[0020] Preferably, the mounting frame includes a fixed frame that is fixedly mounted on the lifting platform of the lifting module and a movable frame that is slidably mounted on the fixed frame in a horizontal direction. The adjusting frame is mounted on the movable frame, and the fixed frame is equipped with a second driving component for driving the movable frame to move.

[0021] By adopting the above technical solution, after the traveling vehicle moves to the cutting position, the moving frame can be driven to slide by the second drive component, thereby achieving fine adjustment of the cutting position of the cutting machine without adjusting the position of the entire traveling vehicle, thus improving the convenience of use.

[0022] Preferably, the second drive assembly includes a lead screw and a fourth drive member. The lead screw extends in the sliding direction of the movable frame and is rotatably mounted on the fixed frame. The movable frame is threaded onto the lead screw, and the fourth drive member is used to drive the lead screw to rotate.

[0023] By adopting the above technical solution, the fourth driving component drives the lead screw to rotate, thereby driving the moving frame to move. This structure has high driving stability.

[0024] Preferably, the vehicle is a tracked vehicle.

[0025] By adopting the above technical solution, it is possible to move around in muddy construction sites.

[0026] In summary, this application includes at least one of the following beneficial technical effects:

[0027] 1. When cutting is required, the traveling vehicle moves to the cutting position. Then, according to the shape of the side wall, the angle of the lifting module is adjusted by the first drive component, and the rotation angle of the adjusting frame is adjusted by the adjusting component, so that the cutting direction of the cutting machine corresponds to the side wall. Then, the cutting machine is started, and the movement of the traveling vehicle and the lifting module drive the mounting frame to move, thereby driving the cutting machine to cut along the height direction of the side wall. The above structure can adjust the position of the cutting machine according to the angle of the side wall, which can meet the cutting construction in more construction scenarios. Moreover, the use of automated cutting improves the overall cutting efficiency.

[0028] 2. After cutting, the constraint on the first elastic element is released by the limiting component. The elasticity of the first elastic element pushes the drive rack to slide. The drive rack can then drive the arc-shaped cover to slide out of the arc-shaped protective cover by engaging with the toothed teeth. The top of the drive rack extends out of the sliding groove. By pressing the drive rack that extends out of the sliding groove, the arc-shaped cover can be driven to slide in the opposite direction until the arc-shaped cover retracts into the arc-shaped protective cover. Finally, the driving rack is limited by the limiting component. This process drives the arc-shaped cover to slide with high stability and is easy to operate.

[0029] 3. After cutting, the adjusting screw drives one end of the two connecting rods connected to the adjusting screw to move away from each other, which drives the adjusting frame to rotate towards the mounting frame. At this time, the pushing rod can extend into the moving groove and push the locking rod, causing the hole wall of the perforation to leave the locking groove, thus unlocking. When the driving rack is pressed, the driving connecting rod changes, causing the pushing rod to leave the moving groove. The second elastic element drives the locking rod to reset, and at the same time, the hole wall of the perforation is locked into the locking groove. The above process does not require an additional power source, reducing costs and ensuring high synchronization. Attached Figure Description

[0038] The following is in conjunction with the appendix Figure 1-6 This application will be described in further detail.

[0039] This application discloses a device for cutting visible joints in subway side walls. (Refer to...) Figure 1 The subway side wall surface seam cutting equipment includes a traveling vehicle 1, a lifting module 2, a mounting frame 3, an adjusting frame 4, and a cutting machine 5. The traveling vehicle 1 is a tracked vehicle. The lifting module 2 is installed at the forward end of the traveling vehicle 1. One end of the lifting module 2 is hinged to the traveling vehicle 1, and the other end extends upward. The mounting frame 3 is fixedly installed on the lifting platform of the lifting module 2. One end of the adjusting frame 4 is hinged to the mounting frame 3, and the cutting machine 5 is installed at the other end of the adjusting frame 4. The mounting frame 3 is equipped with an adjusting component 6 for adjusting the rotation position of the adjusting frame 4, thereby driving the cutting machine 5 to move away from the lifting module 2, improving the convenience of cutting the side wall. The traveling vehicle 1 is equipped with a first driving component 11 for driving the lifting module 2 to rotate. The first driving component 11 is a cylinder. The cylinder is tilted and hinged to the traveling vehicle 1. The piston rod of the cylinder is hinged to the lifting module 2, thereby adjusting the cutting direction of the cutting machine 5.

[0040] Reference Figure 1The mounting frame 3 includes a fixed frame 31 and a movable frame 32. The fixed frame 31 is fixedly mounted on the lifting platform of the lifting module 2 and extends horizontally. The movable frame 32 is slidably mounted on the fixed frame 31 along its length. The adjusting frame 4 is mounted on the movable frame 32. The fixed frame 31 is equipped with a second drive assembly, which includes a lead screw 311 and a fourth drive member 312. The lead screw 311 extends in the sliding direction of the movable frame 32 and rotates to mount the mounting frame 3 on the fixed frame 31. The movable frame 32 is threaded onto the lead screw 311. The fourth drive member 312 is a motor and is fixedly mounted on the fixed frame 31. The output shaft of the fourth drive member 312 is fixedly mounted on the lead screw 311, thereby driving the lead screw 311 to rotate and the movable frame 32 to move, thus adjusting the position of the cutting machine 5 in the horizontal direction.

[0041] Reference Figure 1 , Figure 2 and Figure 3 The adjusting assembly 6 includes an adjusting screw 61, a connecting rod 62, a sliding block 63, and a second driving component 64. The adjusting screw 61 is rotatably mounted on the movable frame 32 and extends in the sliding direction of the movable frame 32. The two ends of the adjusting screw 61 are provided with threads in opposite directions. The sliding block 63 is slidably mounted on the adjusting frame 4 in the length direction of the adjusting frame 4. Moving blocks 65 are threadedly installed at both ends of the opposite threads of the adjusting screw 61. A pair of connecting rods 62 are provided, both of which are horizontally arranged, and one end of each connecting rod 62 is hinged to one of the two moving blocks 64. 5. The other ends of the two connecting rods 62 are simultaneously hinged to a connecting block, which is hinged to the sliding block 63. The hinge rod between the connecting rod 62 and the connecting block is vertical, while the hinge rod between the connecting block and the sliding block 63 is horizontal. The second driving component 64 is a motor, which is fixedly installed on the moving frame 32. The output shaft of the second driving component 64 is fixedly installed on the end of the adjusting screw 61. Thus, when the adjusting screw 61 is driven to rotate, the adjusting frame 4 can be driven to rotate, thereby adjusting the cutting machine 5 to move away from the moving frame 32, improving ease of use.

[0042] Reference Figure 4 and Figure 5 An arc-shaped protective cover 41 is installed on the adjusting frame 4 corresponding to the cutting machine 5 to block the splashing of cutting fluid and debris. An arc-shaped groove 411 is opened inside the arc-shaped protective cover 41, which extends along the arc direction of the arc-shaped protective cover 41. An arc-shaped shield 412 is slidably installed in the arc-shaped groove 411. An opening is opened at the top end of the arc-shaped protective cover 412 for sliding out. The adjusting frame 4 is equipped with a first driving component 7 for driving the arc-shaped shield 412 to slide out, so that after cutting is completed, the arc-shaped shield 412 is driven out to block the cutting blade of the cutting machine 5.

[0043] The first drive assembly 7 includes a drive rack 71 and a first elastic element 72. A sliding groove 42 is provided in the adjusting frame 4. The sliding groove 42 is located on the outer arc surface of the arc-shaped protective cover 41 and extends along the length of the adjusting frame 4, with its top end extending beyond the top of the adjusting frame 4. The drive rack 71 is slidably installed in the sliding groove 42. A connecting hole 413 is provided on the side of the arc-shaped protective cover 41 near the sliding groove 42. The connecting hole 413 is connected to the sliding groove 42. The outer arc surface of the arc-shaped protective cover 412 is provided with teeth along the circumference. The drive rack 71 meshes with the teeth. Therefore, when the drive rack 71 slides in the sliding groove 42, it can drive the arc-shaped protective cover 412 to slide.

[0044] The first elastic element 72 is a spring, which is fixedly installed between the bottom end of the drive rack 71 and the sliding groove 42. When the first elastic element 72 is in a compressed state, the arc-shaped cover 412 is in the arc-shaped groove 411, and the top end of the drive rack 71 is at the top of the sliding groove 42. The adjusting frame 4 is equipped with a limiting component 8 for limiting the first elastic element 72 to be in a compressed state. When the limiting component 8 releases the restraint on the first elastic element 72, the drive rack 71 slides and drives the arc-shaped cover 412 to slide out of the arc-shaped protective cover 41. At this time, the top end of the drive rack 71 extends out of the top of the adjusting frame 4. When it is necessary to drive the arc-shaped cover 412 back to the outside of the arc-shaped protective cover 41, the end of the drive rack 71 located outside the adjusting frame 4 can be pressed directly, and the first elastic element 72 can be restricted again by the limiting component 8.

[0045] Reference Figure 4 and Figure 6 The limiting component 8 includes a locking rod 81 and a third driving member. The adjusting frame 4 has a moving groove 43 connected to the sliding groove 42. The moving groove 43 extends in a direction perpendicular to the sliding groove 42. The locking rod 81 is slidably installed in the moving groove 43. A through hole 811 is provided on the locking rod 81 at the position corresponding to the driving rack 71. The driving rack 71 passes through the through hole 811 and is inserted into the locking rod 81. A locking groove 711 is provided on the side wall of the driving rack 71 at the position corresponding to the through hole 811. The hole wall of the through hole 811 is engaged in the locking hole. The third driving member is used to drive the locking rod 81 to slide, thereby driving the hole wall of the through hole 811 to engage or disengage from the locking hole, thereby limiting the first elastic member 72.

[0046] The third driving component includes a second elastic element 82 and a push rod 83. The second elastic element 82 is a spring and is fixedly installed on the locking rod 81 and the bottom of the moving groove 43. The moving groove 43 is opened at the position corresponding to the connecting rod 62, and the end of the moving groove 43 near the connecting rod 62 extends out of the adjusting frame 4. The locking groove 711 is opened on the side of the driving rack 71 away from the connecting rod 62. When the second elastic element 82 is in its natural state, the hole wall of the through hole 811 is inserted into the locking groove 711. The push rod 83 is fixedly installed on the connecting rod 62 and is located at the position corresponding to the moving groove 43. Therefore, when the cutting is completed and the adjusting frame 4 is rotated back, the push rod 83 can extend into the locking groove 711 to push the locking rod 81, so that the hole wall of the through hole 811 leaves the locking groove 711.

[0047] The implementation principle of a subway side wall open seam cutting device according to an embodiment of this application is as follows: In use, the adjusting frame 4 is initially moved to the corresponding position by the traveling vehicle 1, and then the second driving component 64 is activated to drive the adjusting screw 61 to rotate, causing the adjusting frame 4 to rotate towards the side wall; then the position of the moving frame 32 is adjusted by activating the fourth driving component 312 to achieve precise adjustment of the cutting position of the cutting machine 5 in the horizontal direction; then cutting is performed, and during the process, the lifting module 2 drives the cutting machine 5 to move and complete the cutting of the entire open seam; after the cutting is completed, the lifting module 2 is reset; then the second driving component 64 is activated to drive the adjusting screw 61 to rotate in the opposite direction, thereby pulling back the adjusting frame 4 until the pushing rod 83 extends into the moving groove 43, pushing the locking rod 81 to slide, unlocking the first elastic element 72, thereby causing the arc-shaped protective cover 412 to slide out of the arc-shaped protective cover 41, thereby blocking the cutting blade of the cutting machine 5.

[0048] The above are all preferred embodiments of this application, and are not intended to limit the scope of protection of this application. Therefore, all equivalent changes made in accordance with the structure, shape and principle of this application should be covered within the scope of protection of this application.
