Technical Field

[0001] The invention belongs to the technical field of municipal construction, in particular to a culvert transportation device for municipal construction. Background Art

[0002] In the construction of municipal engineering, the transportation and loading and unloading of culverts are important links. As a key component of urban drainage, water supply and other infrastructure construction, culverts are usually used in large quantities and in various specifications. Their quality and integrity play a decisive role in the long-term stable operation of the entire municipal engineering. Traditional culvert loading and unloading methods mostly rely on large-scale mechanical equipment such as cranes and forklifts. However, in some remote areas such as mountainous areas, the geographical environment is complex and transportation is inconvenient, making it difficult for large-scale mechanical equipment to enter the construction site.

[0003] On the one hand, the roads in these areas are narrow and rugged, and the mobility of cranes and forklifts is limited, making it difficult to smoothly reach the culvert loading and unloading sites. Even if some sections of the road are barely passable, their carrying capacity may not be able to meet the weight of large equipment, which is easy to cause damage to road infrastructure, further increasing the difficulty and cost of construction. On the other hand, during transportation, culverts are prone to displacement and collision due to inertia, affecting the quality of the culverts.

It should be understood that the specific embodiments described herein are only used to explain the present invention and are not intended to limit the present invention. The technical solutions of the present invention are described in detail below in conjunction with the embodiments and the accompanying drawings, but the scope of protection is not limited thereto.

[0018] See also Figures 1 to 9 This embodiment proposes a culvert transportation device for municipal construction, including: a vehicle body 1, a vehicle head 2 is fixedly connected to the right end of the vehicle body 1 to facilitate driving and controlling the device, wheels 3 are rotatably connected to the bottom of the vehicle body 1, and baffles 4 are fixedly connected to both sides of the top of the vehicle body 1 to prevent the culvert from accidentally falling during transportation.

[0019] A hydraulic press 10 is rotatably connected inside the vehicle body 1, and a fixed plate 9 is rotatably connected at the driving part of the hydraulic press 10. A loading and unloading plate 5 is fixedly connected to one side of the fixed plate 9. The loading and unloading plate 5 is rotatably connected to the end of the vehicle body 1 away from the front 2. A first support plate 8 is fixedly connected to the upper right side of the loading and unloading plate 5. A hydraulic buffer damper 11 is rotatably connected inside the vehicle body 1, and the driving part of the hydraulic buffer damper 11 is connected to one end of the loading and unloading plate 5. When it is necessary to load and unload the culvert, the loading and unloading plate 5 is driven by the hydraulic press 10 to be unfolded and flattened to provide support for the culvert; when it is necessary to transport, the loading and unloading plate 5 is driven by the hydraulic press 10 to be folded. When the loading and unloading plate 5 is upright and folded, the culvert in the vehicle body 1 can be limited and protected. At the same time, the first support plate 8 is flush with the bottom surface of the vehicle body 1, and with the cooperation of the hydraulic buffer damper 11, safer and more reliable loading and unloading can be achieved.

[0020] The first pressure plate 14 and the second pressure plate 34 are slidably connected to the top of the vehicle body 1; the second pressure plate 34 is close to the front 2 side, and the first pressure plate 14 is close to the rear side; a double-sided rack 21 is fixedly connected to the middle of the bottom of the first pressure plate 14 and the middle of the bottom of the second pressure plate 34, and the bottom of the double-sided rack 21 is fixedly connected to the first return spring 23, and the bottom of the first return spring 23 is fixedly connected to the inside of the vehicle body 1, and the two sides of the double-sided rack 21 are meshed with large gears 22, and the middle of the large gear 22 is fixedly connected with a first bevel gear 26, and the side of the first bevel gear 26 is meshed with a second bevel gear 27, and the middle of the second bevel gear 27 is fixedly connected with a reciprocating screw 19, and the two sides of the reciprocating screw 19 are threadedly connected with a clamping plate 7, and the clamping plate 7 is slidably connected to the top of the vehicle body 1; the first pressure plate 14 and the second pressure plate 34 are respectively provided with a clamping plate 7. The clamping plate 7 is connected to the transmission of a series of gears, bevel gears and reciprocating screws 19 through the double-sided rack 21, and can be automatically clamped according to the position of the culvert to ensure transportation safety.

[0021] A top column 28 is provided inside the vehicle body 1, and one side of the top column 28 is connected to the vehicle body 1 through a second return spring 30; when the top column 28 is upright, the top of the top column 28 contacts the bottom of the first pressure plate 14, which is used to support the first pressure plate 14. A linkage structure is connected between the second pressure plate 34 and the top column 28. The top column 28 not only supports the first pressure plate 14 during loading, but also adjusts its position to facilitate unloading through a linkage structure such as a lever associated with the second pressure plate 34 during the subsequent unloading process.

[0022] The linkage structure includes a first inclined plate 32, a second inclined plate 33, a lever 18 and a movable plate 29; the second pressure plate 34 is symmetrically rotatably connected to the second inclined plates 33 on both sides of the bottom, the other end of the second inclined plate 33 is hinged to one end of the lever 18, the other end of the lever 18 is hinged to the bottom end of the first inclined plate 32, the upper end of the first inclined plate 32 is hinged to one end of the movable plate 29, and the other end of the movable plate 29 is rotatably connected to the top of the corresponding top column 28; through this series of structures, the top column 28 can be driven to deflect, thereby releasing the support for the first pressure plate 14, creating conditions for the movement of the culvert on the first pressure plate 14 during subsequent unloading, and realizing the mechanical linkage between different components during loading and unloading.

[0023] A second support plate 17 is hinged at the lower middle of the lever 18, and the second support plate 17 is fixedly connected to the inside of the vehicle body 1. A limiting column 31 is hinged at the middle of the first inclined plate 32, and the limiting column 31 is fixedly connected to the inside of the vehicle body 1; the second support plate 17 and the limiting column 31 enable the movable plate 29 to move along a predetermined trajectory and amplitude when driving the top column 28 to deflect, thereby ensuring the reliability and accuracy of the entire linkage structure and preventing abnormal situations such as excessive deflection or jamming.

[0024] The first pressure plate 14 and the second pressure plate 34 are both provided with a cylinder 35 at the bottom, and the first pressure plate 14 and the second pressure plate 34 are both provided with a first button 20 on one side; the first button 20 on one side of the first pressure plate 14 is electrically connected to the cylinder 35 at the bottom of the first pressure plate 14; the first button 20 on one side of the second pressure plate 34 is electrically connected to the cylinder 35 at the bottom of the second pressure plate 34; when the first pressure plate 14 moves upward, it will touch the first button 20 on one side, so that the cylinder 35 under the first pressure plate 14 will be reset; similarly, when the second pressure plate 34 moves upward, it will touch the first button 20 on one side, so that the cylinder 35 under the second pressure plate 34 will be reset. After the unloading operation is completed, the equipment can automatically return to the initial or ready state for the next round of loading and unloading operations.

[0025] A first conveying device 6 and a second conveying device 15 are sequentially installed in the vehicle body 1 from the rear to the front 2. Both the first conveying device 6 and the second conveying device 15 are existing belt transmission mechanisms. The first pressure plate 14 is located between the first conveying device 6 and the second conveying device 15, and the second pressure plate 34 is located inside the second conveying device 15. A first motor 12 is fixedly connected to the vehicle body 1 near the rear. The driving part of the first motor 12 is fixedly connected to the driving shaft of the first conveying device 6. A second motor 16 is fixedly connected to the middle of the vehicle body 1. The driving part of the second motor 16 is fixedly connected to the driving shaft of the second conveying device 15. Rollers 13 are arranged in the middle of the first conveying device 6 and the second conveying device 15. During loading and unloading, the forward and reverse rotation of the first motor 12 and the second motor 16 combined with the operation of the first conveying device 6 and the second conveying device 15 provide power and guidance for the movement of the culvert in the vehicle body 1, and are key components for realizing the position adjustment of the culvert during the automatic loading and unloading and transportation of the culvert.

[0026] A second button 24 is fixedly connected inside the vehicle body 1. When the second pressure plate 34 moves downward, the top of the second button 24 can contact the second pressure plate 34. The second button 24 is electrically connected to the second motor 16. When the second button 24 is touched, the second motor 16 stops working. This ensures that the culvert stops conveying after being loaded to a suitable position, provides accurate timing control for subsequent clamping and fixing operations, and ensures the orderliness of the entire loading process. A third button 25 is fixedly connected inside the vehicle body 1. When the first pressure plate 14 moves downward, the top of the third button 25 can contact the first pressure plate 14. The third button 25 is electrically connected to the first motor 12. When the third button 25 is touched, the first motor 12 stops working, thereby controlling the operation of the first conveying device 6.

[0027] It should be noted that when the first pressure plate 14 and the second pressure plate 34 are raised to the maximum height, the transportation of the culvert will not be affected.

[0028] The working principle of the culvert transportation equipment for municipal construction provided by the present invention is as follows: When the culvert needs to be loaded and unloaded, the hydraulic press 10 is started, and the hydraulic press 10 drives the fixed plate 9 to move, thereby causing the loading and unloading plate 5 to rotate around the connection point with the vehicle body 1, so as to realize the deployment or folding of the loading and unloading plate 5, and the hydraulic buffer damper 11 plays a buffering role to prevent the loading and unloading plate 5 from moving too violently during the rotation process and causing impact on the culvert.

[0029] Load the first culvert: The first motor 12 and the second motor 16 are started, and the first culvert is first transmitted to the vehicle body 1 through the first transmission device 6; when the culvert passes through the first pressure plate 14, the top column 28 is in an upright state, and the first pressure plate 14 is supported by the top column 28, so as to facilitate the smooth passage of the first culvert; when the first culvert moves to the second pressure plate 34, the second pressure plate 34 moves downward under the action of the first culvert, and at this time, the double-sided rack 21 at the bottom of the second pressure plate 34 is driven to move, and the double-sided rack 21 drives the large gear 22 meshing with it to rotate, and the large gear 22 The first bevel gear 26 fixed in the middle rotates accordingly, and the first bevel gear 26 meshes with the second bevel gear 27 to rotate, and the reciprocating screw 19 in the middle of the second bevel gear 27 rotates accordingly, and the clamping plate 7 matched with the reciprocating screw 19 will make reciprocating linear motion along the reciprocating screw 19, so that the first culvert can be clamped, and the purpose of automatically fixing the first culvert is achieved to prevent the first culvert here from moving or colliding under inertia during transportation; and when the second pressure plate 34 moves, it contacts the second button 24, and the second motor 16 stops rotating.

[0030] When the second pressure plate 34 moves downward, the second inclined plate 33 moves downward, driving one end of the lever 18 to move downward, so that the other end of the lever 18 moves obliquely upward, and then drives the first inclined plate 32 to rotate, so that the movable plate 29 pushes the top column 28, so that the top column 28 is offset, and then the top column 28 leaves the first pressure plate 14, and the first pressure plate 14 resumes the relative active state with the vehicle body 1. When the second culvert moves to the first pressure plate 14, it can move smoothly into the vehicle body 1, which is convenient for loading the subsequent culvert; at the same time, the first pressure plate 14 moves downward under the pressure of the second culvert, and at this time it will drive the first pressure plate 14 to move downward. The double-sided rack 21 at the bottom of the plate 14 moves, and the double-sided rack 21 here drives the large gear 22 meshing with it to rotate, and the first bevel gear 26 fixed in the middle of the large gear 22 rotates accordingly, and the first bevel gear 26 meshes and drives the second bevel gear 27 to rotate, and the reciprocating screw 19 in the middle of the second bevel gear 27 rotates accordingly, and the clamping plate 7 matched with the reciprocating screw 19 will make reciprocating linear motion along the reciprocating screw 19, so that the second culvert can be clamped, thereby achieving the purpose of automatically fixing the second culvert; and when the first pressure plate 14 moves, it contacts the third button 25, and the first motor 12 stops rotating at this time.

[0031] Unloading from the first culvert at the rear: The cylinder 35 at the first pressure plate 14 is started, and the cylinder 35 at the first pressure plate 14 drives the first pressure plate 14 to move upward, so that the clamping plates 7 on both sides of the first pressure plate 14 are relatively separated; at the same time, the first motor 12 is started to drive the first conveying device 6 to operate in the reverse direction, so that the culvert on the first pressure plate 14 moves and is conveyed along the first conveying device 6, and finally the culvert is unloaded through the loading and unloading plate 5. During this process, the first pressure plate 14 has not yet contacted the first button 20 above; Subsequent culvert unloading: Start the cylinder 35 at the second pressure plate 34, and the cylinder 35 at the second pressure plate 34 drives the second pressure plate 34 to move upward, so that the second pressure plate 34 is lifted up; then the clamping plates 7 on both sides of the second pressure plate 34 are relatively separated; at the same time, under the action of the lever 18, the second inclined plate 33, the first inclined plate 32, the movable plate 29, the limit column 31 and the second reset spring 30, the top column 28 is reset to support the first pressure plate 14. At this time, the first pressure plate 14 contacts the first button 20 thereon, so that the cylinder 35 is reset, which is convenient for the subsequent unloading of the culvert and realizes the automatic loading and unloading of the culvert. The culvert can also be automatically loaded and unloaded in remote areas such as mountainous areas where it is inconvenient to use cranes and forklifts, saving costs.

It cannot be determined that the specific embodiments of the present invention are limited to this. For ordinary technicians in the technical field to which the present invention belongs, several simple deductions or substitutions can be made without departing from the present invention, which should be regarded as belonging to the present invention and the scope of patent protection determined by the submitted claims.
