Description

Technical Field

[0001] The utility model belongs to the field of urban planning, and in particular relates to an underground pipe network pre-buried device for urban road construction. Background Art

[0002] The pre-buried underground pipe network for urban roads plays a vital role in urban planning and construction. This primarily involves the pre-buried stormwater and sewage pipes, which collect and discharge rainwater and sewage generated in cities, thereby protecting the environment and public health. Furthermore, the pre-buried underground pipe network also involves the pre-buried pipelines for water supply, drainage, gas, electricity, and other services. The rational layout and efficient operation of these pipelines are crucial for improving urban management efficiency, minimizing impacts on roads, and enhancing the quality of life for citizens.

[0003] When pre-buried underground pipe networks, pipes need to be laid underground according to the design plan, which requires work such as excavation, burial, and filling. When burying, the pipes need to be placed in a pit. However, some pipes are relatively large in size and weight. If the pipes are laid and placed manually, the labor intensity will be greatly increased. Therefore, a pre-buried underground pipe network device for urban road construction is proposed.

[0008] Furthermore, the lifting frame is slidably connected to the support frame in the vertical direction, and a rotatable first screw rod is provided on the support frame. The first screw rod passes through the lifting frame in the vertical direction and is threadedly connected thereto.

[0026] The following will be combined with the accompanying drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the embodiments described are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0027] like Figure 1 As shown, a pre-buried device for underground pipe networks in urban road construction includes a base 1. The lower end of the base 1 is provided with four universal wheels to facilitate the movement of the device, thereby realizing the transfer of pipes; and the universal wheels are provided with brakes to facilitate the displacement of the device.

[0028] Of course, the number of universal wheels at the lower end of the base 1 includes but is not limited to four. In some embodiments, the number of universal wheels can be more than four, as long as the base 1 can be stably supported and have displacement capability.

[0029] A rotatable turntable 2 is provided at the upper end of the base 1, a support frame 3 is fixed to the upper end of the turntable 2, a lifting frame 5 that can be raised and lowered is provided on the support frame 3, and two connecting plates 7 that can be synchronously slid and adjusted in opposite directions are provided on the lifting frame 5. A clamping assembly 8 is fixed to the lower end of each connecting plate 7. The two clamping assemblies 8 can clamp the pipe at the same time, and the distance between the two clamping assemblies 8 can be adjusted according to the length of the pipe, so as to improve the stability of the pipe clamping. In addition, by controlling the movement of the base 1, the steering of the turntable 2, and the raising and lowering of the lifting frame 5, the pipe can be laid in the excavated tunnel to achieve pre-embedding.

[0030] In this embodiment, a motor is provided at the lower end of the base 1 , and a driving shaft of the motor passes through the base 1 in a vertical direction and is fixed to the turntable 2 , thereby driving the turntable 2 to rotate.

[0031] In this embodiment, the lifting frame 5 is slidably connected to the support frame 3 in the vertical direction. The first screw rod 4 is rotatably connected to the support frame 3. The first screw rod 4 vertically penetrates the lifting frame 5 and is threadedly connected thereto. By providing a motor on the support frame 3 to drive the first screw rod 4 to rotate, the lifting and lowering movement of the lifting frame 5 can be achieved. In addition, in order to ensure that the height position of the lifting frame 5 remains stable after adjustment, the first screw rod 4 needs to have self-locking properties, that is, the thread lead angle of the first screw rod 4 is less than the equivalent friction angle.

[0032] Of course, the method of driving the lifting frame 5 to move up and down includes but is not limited to the first screw rod 4 and other structures in this embodiment. In some embodiments, the lifting frame 5 can also be directly driven to move up and down by setting linear driving components such as cylinders and hydraulic cylinders on the support frame 3.

[0033] In this embodiment, if Figure 2 and Figure 3 As shown, the lifting frame 5 is L-shaped, and a support plate 51 is fixed to the lower end of the lifting frame 5, and the two connecting plates 7 are slidably connected to the support plate 51; two first fixing plates 52 are provided on the support plate 51, and a second screw rod 6 is rotatably connected between the two first fixing plates 52, and the two ends of the second screw rod 6 are respectively provided with a first external thread 61 and a second external thread 62 with opposite rotation directions and equal pitches. The first external thread 61 and the second external thread 62 respectively pass through the two connecting plates 7 and are threadedly connected thereto. By providing a motor on one of the first fixing plates 52 to drive the second screw rod 6 to rotate, the two connecting plates 7 can be synchronously slid in opposite directions, thereby adjusting the distance between the two connecting plates 7 (and even the two clamping assemblies 8) to adapt to the stable clamping of pipes of different lengths;

[0034] Furthermore, in order to ensure that the distance between the two connecting plates 7 remains stable after adjustment, the second screw rod 6 needs to be self-locking, that is, the lead angles of the first external thread 61 and the second external thread 62 are both smaller than the equivalent friction angle.

[0035] Of course, the method of controlling the synchronous reverse sliding of the two connecting plates 7 includes but is not limited to the second screw rod 6 and other structures in this embodiment. In some embodiments, two cylinders can be set on the support plate 51 to drive the two connecting plates 7 to slide synchronously in reverse.

[0036] like Figure 4 As shown, the clamping assembly 8 includes a mounting plate 81 fixed to the lower end of the connecting plate 7. Two connecting blocks 82 that can slide synchronously in opposite directions are provided on the mounting plate 81. A V-shaped clamping block 83 is fixed to the lower end of each of the two connecting blocks 82. The two clamping blocks 83 can slide synchronously in opposite directions to clamp and fix pipes of different diameters.

[0037] In this embodiment, the two connecting blocks 82 are slidably connected to the mounting plate 81. The mounting plate 81 is provided with two second fixing plates 811. A third screw rod 84 is rotatably connected between the two second fixing plates 811. Figure 5 As shown, the ends of the third screw rod 84 are respectively provided with a third external thread 841 and a fourth external thread 842 with opposite rotation directions and equal pitches. The third external thread 841 and the fourth external thread 842 respectively penetrate the two connecting blocks 82 and are threadedly connected thereto. By providing a motor on one of the second fixing plates 811 to drive the third screw rod 84 to rotate, the two connecting blocks 82 can be synchronously slid in opposite directions, that is, the two V-shaped clamping blocks 83 can be driven to slide synchronously in opposite directions.

[0038] Furthermore, in order to ensure stable clamping of the pipe, the third screw rod 84 needs to have self-locking properties, that is, the thread lead angles of the third external thread 841 and the fourth external thread 842 are both smaller than the equivalent friction angle.

[0039] Furthermore, in this embodiment, a through hole is provided on the connecting plate 7 to make way for the third screw rod 84 .

[0040] Of course, the method of driving the two connecting blocks 82 to slide synchronously in opposite directions includes but is not limited to the third screw rod 84 and other structures in this embodiment. In some embodiments, two cylinders can be set on the mounting plate 81 to directly drive the two connecting blocks 82 to slide synchronously in opposite directions, thereby achieving clamping of the pipeline.

[0041] In addition, in this embodiment, a counterweight is provided on the upper end of the base 1 to ensure that the center of gravity of the device is located on the base 1, thereby preventing the device from tipping over due to the center of gravity shift when clamping the pipe.

[0042] Working principle:

[0043] Through setting four universal wheels at the lower end of the base 1, and setting the rotating disc 2 capable of rotating at the upper end of the base 1, the rotating disc 2 is fixed with the support frame 3, the support frame 3 is provided with the lifting frame 5 capable of lifting, the lifting frame 5 is provided with the two connecting plates 7 capable of synchronous reverse sliding adjustment, the lower end of the two connecting plates 7 is respectively fixed with one clamping assembly 8 to clamp the pipeline, through controlling the movement of the base 1, the steering of the rotating disc 2 and the lifting of the lifting frame 5, the pipeline can be laid in the excavated tunnel to realize pre-burying.
