Description

Technical Field

[0001] The invention relates to the technical field of concrete pipe culvert construction, in particular to a concrete circular pipe culvert installation device. Background Art

[0002] Circular culvert is the most commonly used culvert structure type in rural roadbed drainage. It not only has good mechanical properties, but also has simple structure, convenient construction, short construction period and low cost. The most common circular culvert is reinforced concrete circular culvert. The circular culvert consists of two parts: the tunnel body and the tunnel opening. The tunnel body is the main body of the water passage, mainly composed of the tube body, foundation and joints. The tunnel opening is the connecting part of the tunnel body, roadbed and water flow. There are mainly two types of tunnel openings: the eight-shaped wall and the straight wall.

[0003] When installing the concrete circular culvert, after binding the concrete circular culvert with straps, the culvert is usually lifted up with a lifting device or an excavator and fixed with straps, and then placed into a deep trench excavated in advance. However, when docking the culverts, the lifting device swings with a large amplitude, and manual assistance is required each time the docking is performed, such as assisting the culvert to move to the docking position.

[0036] The lifting component 2 includes a C-shaped frame 21. The bottom wall of the C-shaped frame 21 is fixedly connected to the top wall of the workbench 1.

[0037] The support component 5 includes a fixed frame 51. The top wall of the fixed frame 51 is fixedly connected to the right side of the bottom wall of the lifting seat 26. A number of mounting grooves 52 are evenly formed on the outer wall of the fixed frame 51. Adjusting lead screws 54 are rotatably installed on the inner walls of the mounting grooves 52 in the middle. Limiting rods 53 are fixedly installed on the inner walls of the two mounting grooves 52 at the front and back. Slide seats 511 are screwed onto the outer walls of the adjusting lead screws 54.

A driving motor 58 is fixedly installed on the bottom wall of the fixed frame 51. A fixed clamping plate 57 is fixedly installed on the left side wall of the fixed frame 51.

[0038] In this implementation scheme, the lifting component 2 can lift the culvert placed in the medium-depth groove at different depths during work, and then clamp and fix the positions of the outer wall and the top of the inner wall of the culvert through the support component 5 to complete the installation and fixation of the culvert. When docking the culverts, the height of the culvert can also be adjusted by operating the lifting component 2 to match another culvert. The telescopic positioning rods 25 can limit the lifting seat 26 so that it can only move up and down and cannot swing left and right. At the same time, the mutual cooperation of the main lifting rope 23 and the auxiliary lifting ropes 24 can install and tow the lifting seat 26 at multiple positions, making it more stable during lifting.

[0039] Specifically, the workbench 1 is in a "hui" shape and is hollow in the middle. The top wall of the C-shaped frame 21 is hollow. The bottom ends of a number of auxiliary lifting ropes 24 are fixedly connected to the corresponding four-corner top walls of the lifting seat 26. The main lifting rope 23 and a number of auxiliary lifting ropes 24 are all made of high-strength steel ropes. The movable ends of a number of telescopic positioning rods 25 are fixedly connected to the top wall of the lifting seat 26. The bottom wall of the lifting seat 26 is fixedly connected to the top wall of the support component 5.

[0040] In this implementation scheme, the auxiliary lifting ropes 24 are fixedly connected to the corresponding four-corner top walls of the lifting seat 26, which has the effect of stably lifting the lifting seat 26. The hollow top walls of the workbench 1 and the C-shaped frame 21 facilitate the normal passage of the movable ends of the steel ropes.

[0041] Specifically, a plurality of mounting grooves 52 are uniformly arranged in sequence from front to back. The outer walls of the first sliding seat 511 and the second sliding seat 55 are both slidably connected to the inner walls of the corresponding mounting grooves 52. The right side wall of the movable clamping plate 56 is slidably connected to the left side wall of the fixed frame 51. The power shaft of the driving motor 58 passes through the fixed frame 51 through a bearing and is fixedly connected to the bottom end of the adjusting screw rod 54. The outer wall of the movable clamping plate 56 is fixedly connected to the clamping stability assembly 6. Arc-shaped surfaces 510 are provided on both adjacent sides of the fixed clamping plate 57 and the movable clamping plate 56. A dislocation groove 59 is provided on the right side of the bottom wall of the movable clamping plate 56.

[0042] In this implementation scheme, the outer walls of the first sliding seat 511 and the second sliding seat 55 are both slidably connected to the inner walls of the corresponding mounting grooves 52, which can prevent the first sliding seat 511 and the second sliding seat 55 from rotating when moving up and down. The movable clamping plate 56 can slide up and down along the side wall of the fixed frame 51. Arc-shaped surfaces 510 are provided on both adjacent sides of the fixed clamping plate 57 and the movable clamping plate 56, so that the positions of the arc-shaped surfaces 510 are in contact with the arc surface positions of the circular culvert.

[0043] Specifically, the clamping stability assembly 6 includes an electric push rod 66. The electric push rod 66 is located at the top of the movable clamping plate 56. Hinge seats 61 are fixedly installed on the front and rear walls of the movable clamping plate 56. Operating arms 62 are rotatably installed on the inner walls of the two hinge seats 61. The two operating arms 62 are arranged symmetrically in the front and rear. The top end of the operating arm 62 at the front is rotatably installed with the movable end of the electric push rod 66, and the top end of the operating arm 62 at the rear is rotatably installed with the fixed end of the electric push rod 66.

[0044] In this implementation scheme, the electric push rod 66 drives the operating arm 62 to rotate on the inner wall of the hinge seat 61 through the expansion and contraction of its movable end. When the operating arm 62 rotates, it will drive the arc-shaped clamp seat 63 to open or close.

[0045] Specifically, arc-shaped clamp seats 63 are fixedly installed at the bottom ends of the two operating arms 62. Buffer pads 64 are fixedly installed on the inner walls of the two arc-shaped clamp seats 63. Anti-slip pads 65 are fixedly installed on the inner walls of the two buffer pads 64.

[0046] In this implementation scheme, after the operating arm 62 drives the buffer pads 64 and the anti-slip pads 65 to close, it can clamp and fix circular culverts of different specifications, and perform secondary fixation on the culvert to prevent it from disengaging.

[0047] Specifically, the expansion assembly 3 includes two slide rail brackets 31. The two slide rail brackets 31 are arranged symmetrically in the front and rear. The adjacent sides of the two slide rail brackets 31 are both fixedly connected to the outer wall of the workbench 1. Electric slide rails 32 are installed on the inner walls of the two slide rail brackets 31. Electric slide seats 33 are slidably installed on the inner walls of a plurality of electric slide rails 32.

[0048] In this embodiment, with the mutual cooperation of the electric slide rail 32 and the electric slide seat 33, the sliding bracket 35 can be driven to extend outwards, thereby driving the support seat 34, the support column 36 and the moving component 4 to expand outwards, and when facing deep grooves of different widths, the adjustment and adaptation can be completed.

[0049] Specifically, the same sliding bracket 35 is fixedly installed on two electric slide seats 33 in the same orientation. On the left and right sides of the mutually remote sides of the two sliding brackets 35, support seats 34 are fixedly installed. On the bottom walls of a plurality of support seats 34, support columns 36 are fixedly installed. On the adjacent sides of two support columns 36 in the same orientation, connecting frames 37 are fixedly installed. The bottom ends of a plurality of support columns 36 are fixedly connected to the top ends of the corresponding moving components 4.

[0050] In this embodiment, the sliding bracket 35 slides outwards in the inner wall of the corresponding slide rail bracket 31, and drives the support seat 34, the support column 36 and the connecting frame 37 to move outwards. The moving component 4 also moves accordingly, and the expansion width of the whole device can be adjusted to improve the adaptability of the work.

[0051] Specifically, the moving component 4 includes a plurality of mounting cylinders 41. A plurality of mounting cylinders 41 are fixedly connected to the bottom ends of the corresponding support columns 36. On the outer walls of two mounting cylinders 41 on the same side, the same support frame 42 is fixedly installed.

[0052] In this embodiment, with the mutual cooperation of the support frame 42 and the mounting cylinder 41, when the moving component 4 moves along the ground, the connection stability is improved and the strength of the whole moving component 4 is increased.

[0053] Specifically, buffer members 43 are installed in the inner walls of a plurality of mounting cylinders 41. Buffer springs 44 are installed on the outer walls of a plurality of buffer members 43. Support rods 45 are fixedly installed at the bottom ends of a plurality of buffer members 43. Connection seats 46 are fixedly installed at the bottom ends of a plurality of support rods 45.

[0054] In this embodiment, with the mutual cooperation of the buffer member 43 and the buffer spring 44, when the support roller 410 passes through a bumpy road surface, the generated vibration will be buffered and energy-absorbed, improving the stability of the whole device during movement. The mutual cooperation of the support rod 45 and the connection seat 46 is mainly used for connecting the electric steering seat 47 and the support roller 410.

[0055] Specifically, electric steering seats 47 are rotatably installed on the bottom walls of a plurality of connection seats 46. L-shaped frames 48 are fixedly installed on the bottom walls of a plurality of electric steering seats 47. Servo motors 49 are fixedly installed on the inner walls of a plurality of L-shaped frames 48. The power shafts of a plurality of servo motors 49 are fixedly installed with support rollers 410 through bearings through the corresponding L-shaped frames 48.

[0056] In this embodiment, the electric steering seat 47 can adjust the rotation angle of the support roller 410. When encountering a curved deep groove, the support roller 410 can also move along its curved trajectory, improving the functionality of the entire device. The support roller 410 is driven to rotate by the servo motor 49, and the rotation speed of the support roller 410 can be controlled and adjusted. Especially during subsequent docking, when the support roller 410 rotates slowly, the overall accuracy during the docking of the culvert is improved, and it has a good usage effect during operation.

[0057] Working principle of this device: During operation, first, the electric hoist 22, electric slide rail 32, electric slide seat 33, electric steering seat 47, servo motor 49, drive motor 58, and electric push rod 66 are electrically connected through an external power source and a control box. When installing a concrete culvert, the culvert is first unloaded from the transport vehicle in sequence by an external lifting device and hoisted into the excavated deep groove. The placement method of the culverts is arranged one by one according to the docking sequence, and sufficient gaps are reserved between two culverts to facilitate the operation of the entire device for installing and docking the culverts.

[0058] First, adjust the expansion width of the entire device according to the width of the deep groove excavation. The electric steering seat 47 is controlled by the control box to rotate 90 degrees, thereby driving the servo motor 49 and the support roller 410 to rotate 90 degrees to adjust the steering angle of the wheels. Then, the electric slide seat 33 slides along the inner wall of the corresponding electric slide rail 32 on the slide rail bracket 31. When the electric slide seat 33 moves, it drives the sliding bracket 35 to slide outward along the inner wall of the slide rail bracket 31. When the sliding bracket 35 slides, it synchronously drives the support column 36 and the moving component 4 to expand forward and backward. When the moving component 4 expands, the servo motor 49 drives the support roller 410 to rotate along the ground, enabling the width of the entire device to be adjusted by the expansion component 3 to match the width of the deep groove excavation, facilitating the subsequent installation of the culvert. After the sliding bracket 35 and the electric slide seat 33 slide to the appropriate positions, the electric steering seat 47 drives the servo motor 49 and the support roller 410 to rotate 90 degrees again to return to the original position.

[0059] Start the electric hoist 22 to begin loosening the steel rope wound externally, thereby driving the lifting seat 27, the main lifting rope 23, and the auxiliary lifting rope 24 to move downward. When the main lifting rope 23 and the auxiliary lifting rope 24 move downward, they will synchronously drive the lifting seat 26 and the telescopic positioning rod 25 to move downward. The telescopic positioning rod 25 begins to extend downward. When the lifting seat 26 is moving, it will support the assembly 5 and the clamping and stabilizing assembly 6 to move downward into the deep groove. After the support assembly 5 descends into the deep groove, the outer edge height of the top of the culvert is exactly located between the moving clamping plate 56 and the fixed clamping plate 57. At the same time, the movable end of the electric push rod 66 contracts, thereby driving the operating arm 62 to rotate within the inner wall of the hinge seat 61. At the same time, the operating arm 62 drives the arc-shaped clamping seat 63 and the buffer pad 64 to expand and open. Then, start the servo motor 49 to drive the support roller 410 to rotate, thereby driving the moving assembly 4, the expansion assembly 3, the workbench 1, and the entire device to move. When the workbench 1 is moving, it drives the lifting assembly 2, the support assembly 5, and the clamping and stabilizing assembly 6 to move within the deep groove;

[0060] When the moving clamping plate 56 and the fixed clamping plate 57 approach the culvert to be installed, after the continuous rotation of the support roller 410, the fixed clamping plate 57 enters the inside of the culvert until the side wall of the fixing frame 51 is in contact with one end of the culvert. Start the driving motor 58 to drive the adjusting screw rod 54 to rotate. When the adjusting screw rod 54 is rotating, it will drive the sliding seat one 511 to slide downward along the outer wall of the adjusting screw rod 54 within the inner wall of the corresponding installation groove 52. The sliding seat one 511 synchronously drives the moving clamping plate 56 and the clamping and stabilizing assembly 6 to move downward. When the moving clamping plate 56 moves downward, it will drive the sliding seat two 55 to slide downward within the inner wall of the installation groove 52 along the corresponding limiting rod 53, so that the arc-shaped surface 510 parts of the moving clamping plate 56 and the fixed clamping plate 57 are in contact with the outer wall and the inner wall of the culvert. At the same time, the dislocation groove 59 is located at the protruding part outside the culvert. After the moving clamping plate 56 and the fixed clamping plate 57 clamp and fix the position of the top of the culvert;

[0061] Subsequently, the movable end of the electric push rod 66 extends outwards, driving the operating arm 62 to rotate within the inner wall of the hinge seat 61. When the operating arm 62 rotates, it drives the arc-shaped clamping seat 63 and the buffer pad 64 to close, enabling the buffer pad 64 and the anti-slip pad 65 to partially fit the outer wall of the culvert, providing secondary locking for the culvert to prevent insecure fixation. The support roller 410 is driven to rotate by the servo motor 49, driving the entire device and the clamped and fixed culvert to move within the deep groove. When the support roller 410 moves, it encounters a bumpy ground, driving the L-shaped frame 48 to act on the connecting seat 46 and the support rod 45 in the reverse direction. When the support rod 45 is stressed, it drives the buffer member 43 and the buffer spring 44 to buffer and absorb the vibration generated by the bump to prevent the culvert from shaking. Additionally, the telescopic positioning rod 25 can limit the lifting seat 26, preventing the culvert from shaking due to lateral sway during movement. After moving the culvert to the position where it awaits docking with the previously installed culvert;

[0062] The electric hoist 22 is used to loosen or retract the steel rope wound around the outside, driving the lifting seat 27, the main lifting rope 23, and the auxiliary lifting rope 24 to move. When the main lifting rope 23 and the auxiliary lifting rope 24 move, they synchronously drive the lifting seat 26 and the telescopic positioning rod 25 to move. The lifting assembly 2 adjusts the height of the support assembly 5, the clamping and stabilizing assembly 6, and the fixed culvert, making its height match that of the previously installed culvert.

[0063] After the heights and positions of the two culverts awaiting docking are the same, the servo motor 49 drives the support roller 410 to rotate slowly, driving the entire device and the fixed culvert to move slowly for docking and fixation, thus completing the installation operation of the culvert. The entire device can double-fix culverts of different diameters, adapting to the installation operations of culverts of different specifications. When moving, the fixed culvert always maintains a stable posture without significant sway. When the entire device moves on a bumpy road surface, it also buffers to prevent jolting and shaking. It can adjust the appropriate width position of the entire device for deep grooves of different widths, facilitating operations in different terrain environments. When docking, it can quickly adjust the height of the culvert in real-time, facilitating the docking work of the culvert.
