Description

Technical Field

[0001] The present invention relates to the technical field of municipal construction, and particularly to a construction device and a construction method for municipal drainage pipelines. Background Art

[0002] Municipal drainage pipelines are an important part of urban infrastructure, and their main function is to collect and discharge urban rainwater, sewage and other wastewater to ensure the cleanliness and hygiene of the urban environment. With the acceleration of the urbanization process, the continuous growth of the urban population and the continuous increase in water consumption, the construction demand for municipal drainage pipe networks is increasing day by day. Municipal drainage pipelines are usually buried underground, and efficient and accurate equipment and technical support are required during the construction process. In recent years, with the introduction of advanced technologies such as horizontal directional drilling rigs, the construction efficiency and quality of municipal drainage pipelines have been significantly improved. However, there is still much room for improvement in the automation level, operation convenience and construction efficiency of existing construction equipment.

[0003] However, a series of problems that need to be solved urgently have emerged in the actual application of the current technology. Taking the patent with the publication number CN116446792B as an example, this patent proposes a construction device and a construction method for municipal drainage pipelines. The core working principle is to stably and orderly transport the pipeline to the working position of the push-pull assembly through the loading rack, and to achieve the rapid movement of the pipeline through the cooperation of the storage box and the conveyor belt. However, the equipment structure of this patent is complex, involving the linkage of multiple mechanical components, such as a large number of gears, racks, conveyor belts, etc. This not only increases the manufacturing cost of the equipment, but also greatly improves the difficulty of later maintenance.

Detailed implementation manners

[0055] Next, the technical solutions in the embodiments of the present invention will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present invention.

[0056] To make the above objects, features, and advantages of the present invention more obvious and understandable, the present invention will be further described in detail below in conjunction with the accompanying drawings and specific implementation manners.

[0057] Referring to Figure 1-2 , the first aspect of the present invention provides a construction device for municipal drainage pipes, which mainly consists of a horizontal directional drill and a loading component.

[0058] The horizontal directional drill includes a fixed plate 1, a flipping plate 2, a sliding frame assembly 3, a supporting bracket 4, a pushing and pulling assembly 5, and a reset assembly 6. The fixed plate 1 is the basic support structure of the entire device. The flipping plate 2 is arranged on the upper surface of the fixed plate 1 in a flippable manner and can adjust the angle according to construction requirements. Specifically, one end of the flipping plate 2 along its length direction is hinged to the upper surface of the fixed plate 1, and one end of a telescopic rod is hinged to the lower surface of the flipping plate 2, and the other end of the telescopic rod is hinged to the upper surface of the fixed plate 1. The telescopic rod can be an electric push rod or a hydraulic push rod, etc. By changing the length of the telescopic rod, the angle adjustment process of the flipping plate 2 can be realized. The sliding frame assembly 3 is fixedly connected to the upper surface of the flipping plate 2. The supporting bracket 4 is used to support the drainage pipe, and the supporting bracket 4 is slidably connected to the sliding frame assembly 3 along a direction perpendicular to the flipping plate 2. The pushing and pulling assembly 5 clamps and drives the drainage pipe to move along the length direction of the flipping plate 2 in a releasable manner to respectively realize the processes of pipe drilling and pipe pulling back. During the process of the pushing and pulling assembly 5 driving the drainage pipe to move along the length direction of the flipping plate 2, the supporting bracket 4 can be driven to move closer to the flipping plate 2. The reset assembly 6 is used to drive the supporting bracket 4 to move away from the flipping plate 2.

[0059] The feeding assembly includes a storage box 7 and a feeding rack 9. The storage box 7 is fixedly connected to the flipping plate 2, preferably located obliquely above the supporting bracket 4, and is used to store the drainage pipes. An outlet 8 is arranged at its lower end. The feeding rack 9 is slidably connected to the sliding frame assembly 3 along the width direction of the flipping plate 2 and can open and close the outlet 8. The bottom plate of the storage box 7 is provided with a slope, and the slope is towards the outlet 8. The drainage pipes placed in the storage box 7 can slide to the outlet 8 under the action of gravity.

[0060] When the supporting bracket 4 reciprocates once along the direction of approaching and departing from the flipping plate 2, the reset assembly 6 can drive the feeding rack 9 to reciprocate once along the direction of departing from and approaching the supporting bracket 4. During this process, one of the drainage pipes in the storage box 7 can be synchronously transferred to the supporting bracket 4 through the outlet 8 and the feeding rack 9.

[0061] Refer to Figure 3 and Figure 7 As shown in [relevant figure numbers], the sliding frame assembly 3 is fixedly connected to the upper surface of the flipping plate 2 and includes a U-shaped frame 301 and two sliding frames 302 fixedly connected to both sides of the U-shaped frame 301. The U-shaped frame 301 is a channel steel structure, and its opening faces the flipping plate 2. The cross-section of the sliding frame 302 is a "7"-shaped structure, and the supporting bracket 4 is slidably connected between the upper ends of the two sliding frames 302.

[0062] The reset assembly 6 is installed in the U-shaped frame 301 and includes a sliding rail 601, a sliding block 602, a first connecting rod 604, a second connecting rod 605, and a first elastic member 606 which are arranged in one-to-one correspondence. Referring to Figure 5, the cross-section of the slide rail 601 along the direction perpendicular to the flipping plate 2 is an "I"-shaped structure, and it is fixedly connected to the top plate of the U-shaped frame 301 and the side wall away from the loading rack 9. Referring to Figure 6 , one end of the slider 602 away from the loading rack 9 is provided with a sliding port, the sliding port is slidably connected to the slide rail 601 along the direction perpendicular to the flipping plate 2, and an inclined surface 603 is provided on the side of the slider 602 adjacent to the loading rack 9. The first connecting rod 604 is arranged along the direction perpendicular to the flipping plate 2, and the slider 602 is fixedly connected to the supporting bracket 4 through the first connecting rod 604. Referring to Figure 8 , the second connecting rod 605 is arranged along the direction parallel to the flipping plate 2, one end of the second connecting rod 605 is slidably connected to the inclined surface 603, and the other end is fixedly connected to the loading rack 9. The first elastic member 606 is sleeved on the periphery of the second connecting rod 605 and is used to drive the second connecting rod 605 to move along the direction close to the inclined surface 603.

[0063] When the supporting bracket 4 moves towards the flipping plate 2, it can drive the slider 602 to move towards the flipping plate 2, thereby compressing the first elastic member 606, and driving the second connecting rod 605 and the loading rack 9 to move away from the supporting bracket 4; conversely, when the supporting bracket 4 moves away from the flipping plate 2, it can drive the slider 602 to move away from the flipping plate 2, and under the action of the first elastic member 606, the second connecting rod 605 drives the loading rack 9 to move towards the supporting bracket 4.

[0064] Referring to Figure 4 and Figure 8 , in order to improve the sliding effect between one end of the second connecting rod 605 and the inclined surface 603, a mounting plate 10 is fixedly connected to one end of the second connecting rod 605, a roller 11 is mounted on the mounting plate 10, and the roller 11 is in rolling connection with the inclined surface 603.

[0065] In addition, a plurality of positioning rings 12 corresponding to the second connecting rod 605 one by one are fixedly connected to the side wall of the U-shaped frame 301 close to the loading rack 9, the positioning rings 12 are fixedly arranged through the side wall of the U-shaped frame 301, and the second connecting rings are correspondingly movably arranged through the positioning rings 12 one by one. The first elastic member 606 is preferably a first compression spring, the first compression springs are correspondingly sleeved on the periphery of the second connecting rod 605, one end of the first compression spring is connected to the mounting plate 10, and the other end of the first compression spring is connected to the positioning ring 12.

[0066] In order to improve the stability of the U-shaped frame 301 during the movement along the direction perpendicular to the flipping plate 2, a plurality of sliding rods 608 are further fixedly connected to the lower surface of the U-shaped frame 301 of the present invention, and the sliding rods 608 are slidably connected to the U-shaped frame 301 along the direction perpendicular to the flipping plate 2.

[0067] Referring again to Figure 1-2, the push-pull assembly 5 includes a driving member 501, a driven member 502, a screw rod 505, and a driving motor 506. The driving member 501 is slidably connected to the upper end of the sliding frame 302 along the length direction of the flipping plate 2, and can clamp and drive the drainage pipe to move along the length direction of the flipping plate 2. The axial direction of the drainage pipe is parallel to the length direction of the flipping plate 2. The process of the drainage pipe moving along the length direction of the flipping plate 2 is the process of moving along its axial direction; the driven member 502 is adjacent to the hinged end of the flipping plate 2 and the fixed plate 1, and the driven member 502 is fixedly connected to the upper end of the sliding frame 302 for clamping the drainage pipe. Two mounting seats 503 and a motor support 504 are installed on the sliding frame 302 away from the loading rack 9. The screw rod 505 is rotatably connected between the two mounting seats 503. The screw rod 505 is arranged along the length direction of the flipping plate 2. The driving motor 506 is installed on the motor support 504, and the driving motor 506 is in transmission connection with the screw rod 505. The driving member 501 is fixedly connected with a connecting seat 507, and the screw rod 505 is threadedly connected with the connecting seat 507. The driving motor 506 drives the screw rod 505 to rotate, and can realize the process of the driving member 501 moving along the length direction of the flipping plate 2 along the length direction of the flipping plate 2.

[0068] In the present invention, the driving member 501 and the driven member 502 adopt the structures of the prior art, and the rotating sleeve and fixed sleeve structures in the patent document with the publication number CN112664135B and the name of the construction device and construction method for municipal drainage pipes can be referred to. In addition to both being able to clamp the drainage pipe, the driving member 501 can also drive the drainage pipe to rotate. On the one hand, when the driving member 501 and the driven member 502 respectively clamp different drainage pipes, the driving member 501 can clamp one drainage pipe to rotate, and the driven member 502 fixes the other drainage pipe, so as to realize the threaded connection effect between adjacent drainage pipes; on the other hand, when the drainage pipe is drilled or pulled back, only the driving member 501 drives the drainage pipe to rotate on its own axis. At the same time, by using the driving motor 506 to drive the screw rod 505 to rotate, the effect of driving the drainage pipe to move along its axial direction can be achieved.

[0069] The driving member 501 moves between a first position and a second position on the upper surface of the supporting bracket 4. At the first position, the supporting bracket 4 is embedded between the sliding frames 302, and the loading rack 9 opens the discharge port 8; at the second position, the upper end of the supporting bracket 4 protrudes from the sliding frame 302, and the loading rack 9 abuts against one side of the supporting bracket 4 to move the drainage pipe onto the supporting bracket 4. The first position is on the side of the second position close to the driven member 502. When the flipping plate 2 is inclined, the second position is above the first position, the driven member 502 is below the first position, and the driving member 501 slides between the first position and the second position.

[0070] Preferably, the support bracket 4 is provided with a smooth curved surface along its length direction, and the first position and the second position are both provided on the smooth curved surface. A circular arc surface is also arranged in the smooth curved surface, and the circular arc surface is used to hold the drainage pipe. Specifically, when the drainage pipe is placed on the support bracket 4, the driving member 501 clamps the drainage pipe during the sliding process at the second position, and when it slides to the first position, the drainage pipe is separated from the support bracket 4, and a through hole is provided on the passive member 502, and the drainage pipe can flexibly pass through the through hole to achieve drilling or back-dragging operations.

[0071] Reference Figure 8-11 The upper end of the loading rack 9 is provided with a blocking surface 901 and a sliding surface 902 connected in sequence. The blocking surface 901 is a plane structure, and is used to block the discharge port 8 when the support bracket 4 is in the second position. The sliding surface is a curved surface structure, and its cross section is a "J"-shaped structure. The sliding surface 902 is used to receive the drainage pipe when the support bracket 4 is in the first position. Specifically, the blocking surface 901 is located above the side of the sliding surface 902 away from the support bracket 4. The lower end of the storage box 7 is provided with the discharge port 8. When the driving member 501 is in the second position, the blocking surface 901 is opposite to the discharge port 8, and the discharge port 8 can be blocked. When the driving member 501 is in the first position, the sliding surface 902 is opposite to the discharge port 8, and one of the drainage pipes in the storage box 7 enters the sliding surface 902 through the discharge port 8.

[0072] A plurality of stoppers 14 are rotatably connected to one end of the lower sliding surface 902 near the support bracket 4, which is used to clamp the drainage pipe. A half gear 15 is fixedly connected to one end of the stopper 14, and the half gear 15 is rotatably connected to the loading rack 9. A blind hole is provided on the side wall of the loading rack 9, and a rack 17 is slidably connected in the blind hole. The rack 17 is meshed with the half gear 15 for transmission, and the rack 17 drives the stopper 14 to flip through the second elastic member 16. A groove 607 is provided on one side of the support bracket 4 near the loading rack 9, which corresponds to the rack 17 and the stopper 14 one by one.

[0073] Specifically, the second elastic member 16 is a second compression spring, one end of which is connected to the rack, and the other end of which is connected to the end wall of the blind hole. The elastic force of the second compression spring is less than that of the first compression spring. Under the action of the first compression spring, the rack can be completely embedded in the blind hole. That is, when the loading rack 9 and the supporting bracket 4 are in clearance, the rack, under the action of the second compression spring, a part of it protrudes from the loading rack 9, driving the stop block 14 to flip upward, and at this time, it can cooperate with the lower sliding surface to clamp the drainage pipe. At this time, the drainage pipe tends to rotate toward the stop block 14 and remains relatively still; when the groove 607 interacts with the rack, the rack 17 is gradually embedded in the blind hole, and the stop block 14 flips toward the supporting bracket 4. The drainage pipe lacks the obstruction of the stop block 14 and can slide into the supporting bracket 4 under the action of its own gravity component.

[0074] The beneficial effects of the present invention are as follows:

[0075] a. Through the cooperation of the reset component 6 and the push-pull component 5, the device realizes the automatic feeding and transfer of drainage pipes, ensures the stable transportation and installation of drainage pipes, reduces manual intervention, and improves construction efficiency.

[0076] b. The flip-up design of the flip plate 2 and the arc surface design of the support bracket 4 enable the device to adapt to construction requirements at different angles and terrains, improving the versatility of the device.

[0077] c. Through the cooperation of the drive motor 506 and the screw 505, the operation of the push-pull component 5 is simple and easy. Construction workers only need to control the motor to complete the laying work of drainage pipes, reducing the operation difficulty.

[0078] d. The transmission design of the stop block 14 and the rack 17 ensures the stability of the drainage pipe during transfer, avoiding the risk of pipe dropping or jamming, and improving the reliability of the device.

[0079] e. The present invention does not have a belt structure, and compared with the prior art, the number of gears and racks used is greatly reduced, the complexity of the device is reduced, and the manufacturing cost and maintenance difficulty are reduced.

[0080] On the other hand, the present invention provides a construction method for a construction device for municipal drainage pipes as described above, including the following steps:

[0081] Place the drainage pipe in the storage box 7, ensuring that the drainage pipes in the storage box 7 are neatly arranged for subsequent feeding.

[0082] Use the push-pull component 5 to drive the support bracket 4 to move towards the flip plate 2, causing the feeding rack 9 to move away from the support bracket 4, and open the discharge port 8, so that one drainage pipe in the storage box 7 moves to the feeding rack 9 through the discharge port 8.

[0083] Use the reset component 6 to drive the support bracket 4 to move away from the flip plate 2, causing the feeding rack 9 to move closer to the support bracket 4, and close the discharge port 8, so that the drainage pipe in the feeding rack 9 moves to the support bracket 4.

[0084] The push-pull component 5 clamps and drives the drainage pipe to move along the length of the flip plate 2 to complete the construction work.

[0085] Specifically, the screw rod 505 is driven to rotate by the driving motor 506, so as to drive the driving member 501 to slide along the upper surface of the sliding frame 302, that is, the driving member 501 can be moved between the first position and the second position. When the driving member 501 slides from the second position to the first position, it can drive the supporting frame 4 to move toward the flip plate 2, thereby driving the loading frame 9 to move away from the supporting frame 4. The blocking surface 901 of the loading frame 9 is gradually staggered with the discharge port 8 until the lower sliding surface 902 is opposite to the discharge port 8, so that one of the drainage pipes in the storage box 7 enters the lower sliding surface 902 through the discharge port 8. At this time, under the action of the second elastic member 16, a part of the rack 17 protrudes from the loading frame 9, and the stop block 14 flips upward, and the stop block 14 and the lower sliding surface 902 work together to clamp the drainage pipe.

[0086] The driving motor 506 is used to drive the screw 505 to rotate in the opposite direction, driving the driving member 501 to slide from the first position to the second position. Under the action of the first elastic member 606, the supporting frame 4 can be driven to move in the direction away from the flip plate 2, thereby driving the loading rack 9 to move in the direction close to the supporting frame 4. The lower sliding surface 902 of the loading rack 9 is gradually misaligned with the discharge port 8 until the blocking surface 901 is misaligned with the discharge port 8, thereby achieving the blocking of the discharge port 8. Synchronously, the rack 17 interacts with the groove 607, driving the rack 17 to be gradually embedded in the groove 607. At this time, the stop block 14 can be driven to flip downward, and the pipeline of the loading rack 9 lacks the obstruction of the stop block 14 and can slide into the supporting frame 4.
