Description

Technical Field

[0001] This invention belongs to the technical field of pipeline transportation equipment, and relates to an underground pipeline lifting device and an underground pipeline lifting method. Background Technology

[0002] To meet the technical requirements of mine ventilation, dust removal, and backfilling, a large number of pipelines are often laid out underground. Therefore, ensuring the safety and quality of underground pipeline design and installation has become a crucial aspect of normal mine production. Due to limited underground space, the transportation and storage of pipelines become a burden on normal mine production. Furthermore, traditional methods for pipeline installation, such as manual chain hoists or manual segmented lifting, are slow, require a large number of workers, and, because the pipelines are located inside underground roadways, existing lifting equipment is too large to access, making on-site pipeline installation extremely difficult. Therefore, a new device with underground transportation and pipeline lifting capabilities needs to be developed to address the problems of underground pipeline transportation and installation. Summary of the Invention

[0003] The purpose of this invention is to provide a downhole pipeline lifting device that solves the problems of slow installation speed and large number of construction operators in the prior art when using manual chain hoisting or manual segmented lifting.

[0004] Another object of the present invention is to provide a method for lifting downhole pipelines.

[0005] The technical solution adopted in this invention is an underground pipeline hoisting device, including a transport mechanism. Two hoisting mechanisms are arranged side by side on one side of the upper surface of the transport mechanism. A storage mechanism is also arranged on the upper surface of the transport mechanism corresponding to the positions of the two hoisting mechanisms. The storage mechanism stores the pipeline to be hoisted. A pipeline outlet is arranged on the side of the storage mechanism near the hoisting mechanism. A pipeline receiving mechanism is arranged on the side of the hoisting mechanism near the pipeline outlet. The two pipeline receiving mechanisms are respectively located on both sides of the pipeline outlet.

[0006] The invention is further characterized in that,

[0007] The upper surface of the transport mechanism is also equipped with a platform mounted on a mounting frame. The platform is located at either end of the two lifting mechanisms that are opposite to each other. A ladder is installed between the platform and the upper surface of the transport mechanism, and a guardrail is also installed on the platform.

[0008] The transport mechanism includes a rectangular transport plate, two lifting mechanisms on one side of the upper surface of the transport plate, a storage mechanism on the upper surface of the transport plate and corresponding to the two lifting mechanisms, at least four casters evenly distributed on the lower surface of the transport plate, and a connected groove provided on the transport plate at the position corresponding to the two pipe mounting mechanisms, with the lower end of the pipe mounting mechanism located in the groove.

[0009] The storage mechanism includes a box, the bottom of which slopes downward from the side away from the pipe mounting mechanism to the side closer to the pipe mounting mechanism. The pipe outlet is located at the lower end of the side wall of the box near the pipe mounting mechanism. The side of the box with the pipe outlet is aligned with the side of the groove away from the lifting mechanism. The pipe mounting mechanism is provided with a pipe inlet.

[0010] The lifting mechanism includes two frames arranged side by side on one side of the transport plate. A chain drive mechanism is set on the side of the frame near the pipe outlet. The pipe mounting mechanism is fixed on the drive chain of the chain drive mechanism, and the chain drive mechanism drives the pipe mounting mechanism to move up and down.

[0011] The chain drive mechanism includes drive sprockets fixed to the upper and lower ends of the frame via rotating shafts, a drive chain connected to the two drive sprockets, a pipe mounting mechanism fixed to the drive chain, and the output shaft of a drive motor fixedly connected to the rotating shaft of the drive sprocket at the lower end of the frame.

[0012] The pipe mounting mechanism includes a mounting plate fixed on the transmission chain. A vertical hollow waist-shaped structure is fixed on the other side of the mounting plate. The groove is adapted to the shape of the lower end of the hollow waist-shaped structure. The pipe inlet is set at the middle position on the side of the hollow waist-shaped structure away from the mounting plate. When the pipe mounting mechanism moves on the transmission chain to the position corresponding to the pipe outlet, the pipe inlet and pipe outlet are set accordingly.

[0013] An electric telescopic rod is also fixed on the mounting plate. The telescopic end of the electric telescopic rod extends vertically into the hollow waist-shaped structure from the top. The telescopic end of the electric telescopic rod is connected to a clamping head, which matches the shape of the outer wall of the pipe.

[0014] A guide plate is provided at the lower end of the pipe outlet. When the pipe mounting mechanism moves on the transmission chain to a position corresponding to the pipe outlet, the other side of the guide plate is aligned with the lower part of the pipe inlet.

[0015] An electric slide gate is installed on the box at the outlet of the pipe; the casters are electric wheels; it also includes a controller, which is connected to the electric wheels, electric slide gate, drive motor and electric telescopic rod via cables. The controller is also connected to a remote control via wireless transmission.

[0016] A gravity sensor is also installed at the lower end of the pipe outlet, and the gravity sensor is connected to the controller via a cable.

[0017] The second technical solution adopted in this invention is a downhole pipeline hoisting method, which uses the aforementioned downhole pipeline hoisting device and is implemented according to the following steps:

[0018] The steps involve transporting the transportation equipment to the pipeline installation location;

[0019] The steps are as follows: control the drive motor to drive the chain transmission mechanism to rotate, ensuring that the pipe mounting mechanism of the lifting mechanism moves on the transmission chain to the position corresponding to the pipe outlet. Open the electric slide gate, and the pipe rolls down the slope from the pipe outlet under the action of gravity, passes through the guide plate, and enters the pipe mounting mechanism from the pipe inlet. Start the electric telescopic rod, and the clamping head clamps the pipe between the bottom inner surface of the pipe mounting mechanism. Then start the chain transmission mechanism to drive the pipe along the transmission chain to the required installation position.

[0020] The steps are as follows: the electric telescopic pole is activated and retracted; workers enter the platform and connect the pipes; after the connection is completed, the moving transport mechanism continues to install the next section of pipe, and so on, until the entire pipe installation is completed.

[0021] The beneficial effects of this invention are:

[0022] This invention, through the arrangement of a transportation mechanism, a lifting mechanism, and a storage mechanism, enables the transportation and lifting of pipelines underground. It is easy to install and solves the problems of slow installation speed and large number of construction operators in the prior art, which rely on manual chain hoisting or manual segmented lifting. It greatly reduces manual labor and is small in size, making it suitable for environments with limited space underground. Attached Figure Description

[0029] The present invention will now be described in detail with reference to the accompanying drawings and specific embodiments.

[0030] Example 1

[0031] The underground pipeline hoisting device of the present invention has the following structure: Figure 1-2 As shown, the system includes a transport mechanism 1. Two lifting mechanisms 3 are arranged side by side on one side of the upper surface of the transport mechanism 1. A storage mechanism 2 is also provided on the upper surface of the transport mechanism 1 at the position corresponding to the two lifting mechanisms 3. The storage mechanism 2 stores the pipes 15 to be lifted. A pipe outlet 16 is provided on the side of the storage mechanism 2 near the lifting mechanism 3. A pipe receiving mechanism 11 is provided on the side of the lifting mechanism 3 near the pipe outlet 16. The two pipe receiving mechanisms 11 are respectively located on both sides of the pipe outlet 16.

[0032] The upper surface of the transport mechanism 1 is also equipped with a platform 14 via a mounting frame 4. The platform 14 is located at either end of the two lifting mechanisms 3 that are opposite to each other. A ladder 13 is provided between the platform 14 and the upper surface of the transport mechanism 1. A guardrail is also installed on the platform 14.

[0033] The transport mechanism 1 includes a transport plate 5 configured as a cuboid, two lifting mechanisms 3 disposed on one side of the upper surface of the transport plate 5, a storage mechanism 2 disposed on the upper surface of the transport plate 5 and corresponding to the two lifting mechanisms 3, at least four casters 6 evenly disposed on the lower surface of the transport plate 5, and a communicating groove 17 disposed on the transport plate 5 at the position corresponding to the two pipe mounting mechanisms 11, with the lower end of the pipe mounting mechanism 11 located in the groove 17.

[0034] The storage mechanism 2 includes a box 7. The bottom of the box 7 slopes downward from the side away from the pipe support mechanism 11 to the side near the pipe support mechanism 11. The pipe outlet 16 is located at the lower end of the side wall of the box 7 near the pipe support mechanism 11. The side of the box 7 where the pipe outlet 16 is located is aligned with the side of the groove 17 away from the lifting mechanism 3. The pipe support mechanism 11 is provided with a pipe inlet 18.

[0035] like Figure 3 As shown, the lifting mechanism 3 includes two frames 10 arranged side by side on one side of the transport plate 5. A chain drive mechanism 12 is provided on the side of the frame 10 near the pipe outlet 16. The pipe support mechanism 11 is fixed on the drive chain of the chain drive mechanism 12. The chain drive mechanism 12 drives the pipe support mechanism 11 to move up and down.

[0036] The chain drive mechanism 12 includes a drive sprocket 20 fixed to the upper and lower ends of the frame 10 via a rotating shaft 22. A drive chain 21 is connected to the two drive sprockets. The pipe support mechanism 11 is fixed to the drive chain 21. The output shaft of the drive motor 23 is fixedly connected to the rotating shaft 22 of the drive sprocket 20 at the lower end of the frame 10.

[0037] like Figure 4 As shown, the pipe mounting mechanism 11 includes a mounting plate fixed on the transmission chain 21. A vertical hollow waist-shaped structure 26 is fixed on the other side of the mounting plate. The groove 17 is adapted to the shape of the lower end of the hollow waist-shaped structure 26. The pipe inlet 18 is located at the middle position on the side of the hollow waist-shaped structure 26 away from the mounting plate. When the pipe mounting mechanism 11 moves on the transmission chain 21 to the position corresponding to the pipe outlet 16, the pipe inlet 18 and the pipe outlet 16 are set accordingly.

[0038] An electric telescopic rod 27 is also fixed on the mounting plate. The telescopic end of the electric telescopic rod 27 extends vertically into the hollow waist-shaped structure 26 from the top. The telescopic end of the electric telescopic rod 27 is connected to a clamping head 28, which matches the shape of the outer wall of the pipe 15.

[0039] A guide plate 24 is provided at the lower end of the pipe outlet 16. When the pipe mounting mechanism 11 moves on the transmission chain 21 to a position corresponding to the pipe outlet 16, the other side of the guide plate 24 is aligned with the lower part of the pipe inlet 18.

[0040] An electric slide gate 8 is installed on the housing 7 at the outlet 16 of the pipe; the casters 6 are electric wheels; such as Figure 5 As shown, it also includes a controller 19, which is connected to the electric wheel, the electric sliding door 8, the drive motor 23 and the electric telescopic rod 27 via cables.

[0041] A gravity sensor 9 is also installed at the lower end of the pipe outlet 16, and the gravity sensor 9 is connected to the controller 19 via a cable.

[0042] The working principle of this embodiment is as follows:

[0043] The pipe 15 is transported through the well shaft to the bottom of the well and loaded into the storage mechanism 2 and then transported to the pipe installation position. The controller controls the casters 6 to rotate, and the entire lifting mechanism is transported to the pipe installation position.

[0044] The drive motor 23 drives the chain transmission mechanism 12 to rotate, ensuring that the pipe mounting mechanism 11 of the lifting mechanism 3 moves on the transmission chain 21 to the position corresponding to the pipe outlet 16. The electric slide gate 8 is opened, and the pipe 15 rolls down the slope from the pipe outlet 16 under the action of gravity, passes through the guide plate 24, and enters the pipe mounting mechanism 11 from the pipe inlet 18. The electric telescopic rod 27 is activated, and the clamping head 28 clamps the pipe 15 between the bottom inner surface of the pipe mounting mechanism 11. Then, the chain transmission mechanism 12 is activated to drive the pipe 15 along the transmission chain to the required installation position.

[0045] When a pipe 15 enters the pipe mounting mechanism 11, the controller collects gravity information from the gravity sensor and sets a delay time or advance time based on the actual situation, and controls the electric slide gate 8 to close, so that the next pipe falls down.

[0046] The electric telescopic pole 27 is activated and retracted. Workers enter platform 14 and connect the pipes. After the connection is completed, the moving transport mechanism continues to install the next section of pipe. This process is repeated until the entire pipe installation is completed.

[0047] Example 2

[0048] Based on Embodiment 1, the controller 19 is also connected to a remote control 25 via wireless transmission, and the remote control 25 controls the movement of the electric wheel, the electric sliding door 8, the drive motor 23 and the electric telescopic rod 27.

[0049] Example 3

[0050] Based on Embodiment 1, an installation groove 29 is provided on the upper surface of the transport plate 5 at the position where the transmission sprocket 20 at the lower end of the frame 10 is installed.

[0051] Example 4

[0052] The method for hoisting downhole pipelines, using the downhole pipeline hoisting device in Example 2, is implemented according to the following steps:

[0053] Step 1: Transport the pipe 15 through the well shaft to the bottom of the well and load it into the storage mechanism 2 for transport to the pipe installation location. Control the casters 6 to rotate using the remote control 25 to transport the entire lifting mechanism to the pipe installation location.

[0054] Step 2: Control the drive motor 23 to drive the chain transmission mechanism 12 to rotate, ensuring that the pipe mounting mechanism 11 of the lifting mechanism 3 moves on the transmission chain 21 to the position corresponding to the pipe outlet 16. Open the electric slide gate 8. Under the action of gravity, the pipe 15 rolls down the slope from the pipe outlet 16, passes through the guide plate 24, and enters the pipe mounting mechanism 11 from the pipe inlet 18. Start the electric telescopic rod 27. The clamping head 28 clamps the pipe 15 between the bottom inner surface of the pipe mounting mechanism 11 and the clamping head 28 downward. Then start the chain transmission mechanism 12 to drive the pipe 15 along the transmission chain to the required installation position.

[0055] When a pipe 15 enters the pipe mounting mechanism 11, the controller collects gravity information from the gravity sensor and sets a delay time or advance time based on the actual situation, and controls the electric slide gate 8 to close, so that the next pipe falls down.

[0056] Step 3: Start the electric telescopic pole 27 to retract, and the staff enters the platform 14 to connect the pipes. After the connection is completed, continue to move the transport mechanism to install the next section of pipe. Repeat this process until the entire pipe installation is completed.
