DETAILED DESCRIPTION

[0021] The present invention will be further described below in conjunction with the accompanying drawings and specific embodiments.

[0022] like Figure 1-3As shown, a steep slope pipeline installation device includes a steep slope 1 and a pipeline installation vehicle 2. A track 11 is arranged on the steep slope 1 along the slope direction. The track 11 is fixed with expansion screws and is detachable. The track 11 can be recycled, which is energy-saving and environmentally friendly with low cost. Wheel brackets 21 are respectively installed on the four corners on the front and rear sides of the bottom of the pipeline installation vehicle 2. Wheels 22 are installed on the wheel brackets 21. The pipeline installation vehicle 2 is movably installed on the track 11 through the wheels 22. The width of the wheels 22 is less than the width of the track 11 by 20 cm. A pipeline bracket 23 for placing the pipeline 4 is provided on the pipeline installation vehicle 2. Four pipeline brackets 23 are evenly distributed along the length direction of the pipeline installation vehicle 2. The pipeline bracket 23 is semicircular and compatible with the pipeline 4. The pipeline bracket 23 is provided with an anti-skid pad or a sponge pad on the contact surface with the pipeline 4. In this embodiment, a sponge pad is preferably used. The sponge pad is used to prevent the pipeline 4 from being worn when placed on the pipeline bracket 23. A winch 3 is installed on the steep slope 1 at an oblique position above the pipeline installation vehicle 2. The winch 3 is a fixed single-drum slow winch. The load capacity of the winch 3 is three times the load weight. The bottom of the winch 3 is fixed to the steep slope 1 with expansion screws and anchor bars. The winch 3 includes a first rope 31, which is connected to the pipeline installation vehicle 2. The winch 3 controls the pipeline installation vehicle 2 to move up and down along the steep slope 1 on the track 11.

[0023] When the pipeline is installed by using this device, the pipeline 4 is placed on the pipeline installation vehicle 2, and the other pipeline 41 is installed on the steep slope 1 and is located diagonally below the pipeline installation vehicle 2. The winch 3 controls the pipeline installation vehicle 2 to move diagonally downward along the steep slope 1 toward the other pipeline 41. By utilizing the dead weight of the pipeline 4 and the pipeline installation vehicle 2 and the gravity acceleration on the steep slope 1, the socket of the pipeline 4 can be inserted into the socket of the other pipeline 41 to achieve installation between the pipelines.

[0024] In order to ensure the safety of construction, an emergency locking device 5 is fixed on the steep slope 1 at a position obliquely above the pipeline installation vehicle 2 and adjacent to the winch 3. Figure 4 As shown, the emergency locking device 5 includes a second rope 51, a belt drum 52, a ratchet mechanism 53, a control mechanism 54, an inertia disk 55 and a sensitive mechanism 56. The load weight of the emergency locking device 5 is ten times the load weight. The second rope 51 of the emergency locking device 5 is connected to the pipeline installation vehicle 2. When the second rope 51 encounters an emergency situation such as the pipeline installation vehicle 2 derailing, the first rope 31 of the winch 3 breaking, etc., the inertia disk 55 will trigger the sensitive mechanism 56, and the ratchet mechanism 53 will lock the second rope 51. The second rope 51 is used to lock the pipeline installation vehicle 2 to prevent the pipeline installation vehicle 2 from colliding with the construction personnel, thereby ensuring construction safety.

[0025] During construction, there may be a situation where the positions of the sockets and sockets between the pipes 4 do not correspond. In order to ensure smooth docking between the pipes 4, it is necessary to adjust the positions of the sockets of the pipes 4 up and down and left and right. Therefore, the device is also provided with an adjustment mechanism, including height position adjustment and left and right position adjustment. The specific structure is as follows:

[0026] Height position adjustment: The pipe installation vehicle 2 and the wheel bracket 21 are connected together by a jack 24. One end of the jack 24 is connected to the bottom of the pipe installation vehicle 2, and the other end is connected to the wheel bracket 21. The height of the pipe installation vehicle 2 is adjusted by lifting the jack 24, thereby adjusting the height position of the socket of the pipe 4.

[0027] Left and right position adjustment: The front bottom of the pipe installation vehicle 2 is connected to the jack 24 so as to be movable horizontally left and right through a sliding wheel, and the rear bottom of the pipe installation vehicle 2 is connected to the jack 24 so as to be rotatable through a bearing. A fixed beam 25 is installed between the front and rear wheel brackets 21. A spur rack 29 is fixed to the front bottom of the pipe installation vehicle 2 along its width direction. A gear bracket 26 is fixed to the fixed beam 25 at the position of the spur rack 29. The gear bracket 26 is installed with a connected operating turntable 27 and a gear set 28. The gear set 28 is meshed with the spur rack 29. The operating turntable 27 has a locking structure. The operating turntable 27 can be rotated only when the operating turntable 27 is released. When the operating turntable 27 is rotated, the gear set 28 rotates accordingly. When the gear set 28 rotates, the front side of the pipe installation vehicle 2 is horizontally displaced left and right, and the rear side rotates, thereby adjusting the left and right position of the socket of the pipe 4.

[0028] The use of the above device for pipeline installation has the following advantages:

[0029] 1. Strong adaptability. It can adapt to the installation of pipelines 4 on various steep slopes 1, especially the installation of glass fiber reinforced plastic sand-filled pipes and ductile iron pipes. The width of the pipeline installation vehicle 2 can be changed to adapt to the installation of glass fiber reinforced plastic sand-filled pipes and ductile iron pipes of any diameter.

[0030] Second, the installation speed is fast. Except that manpower is required to fix the pipeline 4 to the pipeline installation vehicle 2 at the beginning, the rest of the process only requires adjusting the winch 3, the jack 24 and the operating turntable 27, and utilizing the deadweight of the pipeline 4 and the pipeline installation vehicle 2 and the gravity acceleration on the steep slope 1, without any external force or a small amount of external force, the spigot can be inserted into the socket to complete the installation of the pipeline 4.

[0031] 3. Less pipe wear. During the installation process, the pipe 4 will not collide or rub against other objects except when it is hung on the pipe installation vehicle 2 and fixed, thus avoiding pipe wear caused by multiple collisions and frictions. At the same time, a sponge pad is installed on the pipe bracket 23, which can effectively reduce pipe wear.

[0032] 4. High safety. Generally, the installation of large-volume glass fiber reinforced plastic sand-filled pipes and ductile iron pipes requires a lot of manpower, hand chain hoists, and various simple gantry frames for installation, which poses great safety hazards. However, this device can greatly reduce manual operations, and is equipped with an emergency locking device 5, which greatly guarantees the construction safety of construction workers.

[0033] The above embodiments are only used to illustrate the present invention and are not intended to limit the present invention in any form. Any person with ordinary knowledge in the technical field may make equivalent embodiments that are partially changed or modified by the technical contents disclosed in the present invention without departing from the scope of the technical features of the present invention, and the equivalent embodiments that do not depart from the technical features of the present invention are still within the scope of the technical features of the present invention.
