Description

Technical Field

[0001] This invention relates to the field of continuous mobile gas supply equipment technology, and in particular to an automatic docking device for mobile gas supply. Background Technology

[0002] Natural gas is a mixture of various hydrocarbon compounds, with methane as its main component. Compared to traditional coal and oil, it produces less carbon dioxide and other pollutants during combustion, resulting in less environmental pollution. At the same time, natural gas has a high calorific value and high combustion efficiency, providing a stable and efficient energy supply for gas-using equipment. It is widely used in various gas-using equipment in industry, commerce, and residential life.

[0003] Currently, when supplying gas to gas-consuming equipment, for short-distance gas supply, flexible hoses are generally used as delivery pipelines to transport natural gas between the gas supply pipeline and the gas-consuming equipment. For gas supply to gas-consuming equipment that is constantly moving over long distances, multiple connection ports are generally installed on both the gas supply pipeline and the gas-consuming equipment. Extended connecting pipes are used to connect the gas supply pipeline ports and the gas-consuming equipment ports. The connection between the connecting pipes and the ports is completed manually. During the gas supply process, the connecting pipes and ports are continuously adjusted and connected to ensure the gas supply to the gas-consuming equipment.

[0004] However, the manual connection method of extending the connecting pipe to the interface requires operators to drag a long pipe to connect the main gas supply pipe and the gas-using equipment, and requires real-time monitoring by the operators. This not only increases the labor intensity of the operators, making them prone to errors due to fatigue during long-term operation, affecting the connection quality, but also easily leads to gas leakage due to wear or damage to the pipe during dragging. In addition, the low efficiency of manual pipe connection can also affect the continuous gas supply to the gas-using equipment. Summary of the Invention

[0005] This invention provides a mobile gas supply automatic docking device to solve the technical problems of high labor intensity and low efficiency in manual docking of pipes and interfaces in the prior art, which leads to poor docking quality and inability to continuously supply gas.

[0006] To solve the above problems, the mobile gas supply automatic docking device provided by the present invention adopts the following technical solution:

[0007] A mobile automatic gas supply docking device, comprising:

[0008] The track support frame is used to install below the main gas supply pipeline, and two parallel running tracks are installed on the track support frame.

[0009] The docking trolleys are multiple in number and are set on the travel track. Each docking trolley includes a support frame, on which an electric actuator, an automatic adjustment component, a travel motor, a docking component, and a controller are mounted.

[0010] The docking assembly includes a docking pipe and a connecting pipe connected to the docking pipe. The upper end of the docking pipe is connected to the electric actuator assembly, and its lower end passes through the automatic adjustment assembly. A docking pipe valve is provided on the docking pipe, and the connecting pipe is used to connect the docking pipe and the gas-using equipment.

[0011] The main gas supply pipeline is provided with multiple gas supply branch pipes arranged at intervals and extending vertically. The radial dimension of the gas supply branch pipe is larger than that of the connecting pipe, and its upper end has a flared opening to accommodate the connecting pipe. The gas supply branch pipe is provided with a branch pipe valve.

[0012] The electric actuator is used to control the up-and-down movement of the connecting pipe under the control of the controller; the automatic adjustment component is used to adjust the position of the connecting pipe; and the traveling motor is used to drive the support frame to move under the control of the controller.

[0013] The beneficial effects of the mobile gas supply automatic docking device provided by this invention are:

[0014] 1) By setting up a track support frame below the main gas supply pipeline, installing a traveling track on the track support frame, and setting up multiple docking trolleys on the track, vertically installed docking pipes for docking with the gas supply branch pipes of the main gas supply pipeline are installed on the support frame of the docking trolleys. Connecting pipes for connecting with gas-consuming equipment are connected to the docking pipes. At the same time, an electric actuator for driving the docking pipes to move up and down, a traveling motor for driving the support frame to move, an automatic adjustment component for adjusting the horizontal position of the docking pipes, and a controller connected to the electric actuator and the traveling motor are installed on the support frame. The controller controls the operation of the electric actuator and the traveling motor, thereby controlling the moving distance of the docking trolleys and controlling the docking pipes to dock with the gas supply branch pipes, so as to realize the gas supply to the gas-consuming equipment.

[0015] 2) When the gas-consuming equipment moves, the docking trolley moves synchronously with the gas-consuming equipment under the control of the controller. Multiple docking trolleys move alternately to continuously supply gas to the gas-consuming equipment, thereby ensuring the continuous operation of the gas-consuming equipment. No manual operation is required, and there is no need to use excessively long delivery pipelines, avoiding the situation where the pipeline is dragged during the movement. In addition, by using docking trolleys instead of manual labor, the docking trolleys will not become fatigued due to long working hours, thus avoiding the situation where poor docking quality is caused by fatigue.

[0016] Through the above-mentioned design, the present invention effectively solves the technical problems of high labor intensity and low efficiency in manual connection of pipes and interfaces in the prior art, resulting in poor connection quality and inability to continuously move and supply gas.

[0017] Furthermore, the support frame includes a horizontal support frame, with a downwardly extending vertical support member at each of the four corners of the horizontal support frame. The electric actuator is mounted on the horizontal support frame, the automatic adjustment component is mounted on the vertical support member, and the walking motor is mounted on the vertical support member.

[0018] Furthermore, the connecting pipe is a plug-in type connecting pipe, which includes a main connecting pipe and a fixing pipe fitted on the main connecting pipe, the fixing pipe being used for fixed installation on the automatic adjustment assembly.

[0019] Furthermore, the connecting pipe is installed on the upper part of the docking main pipe, and a return spring is fitted on the docking main pipe. The two ends of the return spring are fixedly connected to the connecting pipe and the fixed pipe respectively, so as to compress or stretch under the drive of the electric actuator, thereby causing the docking main pipe to descend or rise.

[0020] Furthermore, the electric actuator assembly includes an electric actuator, the output end of which is connected to the upper end of the docking main pipe.

[0021] Furthermore, both the electric actuator and the air supply pipe are equipped with positioners.

[0022] Furthermore, the automatic adjustment component is an automatic adjustment disc, which includes a main disc with a groove. Four adjustment discs corresponding to the four sides of the main disc are installed in the groove. The adjustment discs are connected to the main disc by adjustment springs so that when the docking main pipe is inserted into the air supply branch pipe, the position of the docking main pipe can be adjusted by adjusting the compression or extension of the springs.

[0023] Furthermore, each of the adjusting discs has a quarter-circle arc-shaped notch on the side opposite to the adjusting spring to match the fixing tube, so as to fix the fixing tube.

[0024] Furthermore, both the docking trolley and the gas supply pipe are equipped with gas leakage detection sensors. Attached Figure Description

[0032] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Those skilled in the art should understand that the embodiments described below are only some, not all, of the embodiments disclosed. All other embodiments obtained by those skilled in the art based on the embodiments of the present invention without creative effort are within the scope of protection of the present invention.

[0033] It should be noted that the main concept of the mobile gas supply automatic docking device provided by the present invention is as follows: by setting up a walking track along the extension direction of the main gas supply pipeline, and setting up multiple docking trolleys that can move automatically on the walking track, docking components that can move up and down are installed on the docking trolleys, and the docking pipe in the docking component is connected to the gas supply branch pipe set on the main gas supply pipeline. A connecting pipe is set on the docking pipe, and the other end of the connecting pipe is connected to the gas-using equipment. When the docking pipe moves down and connects with the gas supply branch pipe, the purpose of supplying gas to the gas-using equipment can be achieved; when the gas-using equipment moves, the continuous mobile gas supply to the gas-using equipment can be achieved by the alternating movement of multiple docking trolleys.

[0034] After introducing the basic principles of the present invention, various non-limiting embodiments of the present invention are described in detail below. Any number of elements in the accompanying drawings is for illustrative purposes only and not for limitation, and any naming is for distinction only and has no limiting meaning.

[0035] The principles and spirit of the present invention will be explained in detail below with reference to several representative embodiments.

[0036] Embodiment 1 of the mobile gas supply automatic docking device provided by the present invention:

[0037] like Figures 1 to 3 As shown, the mobile automatic gas supply docking device includes a track support frame 1 and docking trolleys. The track support frame 1 is installed below the main gas supply pipeline 2, and two parallel travel tracks 3 are provided on the track support frame 1. The extension direction of the travel tracks 3 is consistent with the extension direction of the main gas supply pipeline 2. There are two docking trolleys, which are arranged at intervals on the travel tracks 3.

[0038] Regarding the docking trolley: The docking trolley includes a support frame, on which are mounted an electric actuator, an automatic adjustment component, a travel motor 4, a docking component, and a controller. The controller is used to control the electric actuator to drive the docking component to move up and down, and to control the travel motor 4 to drive the support frame to move.

[0039] The structural components of the support frame are described below. The support frame includes a horizontal support frame 5, with a downward-extending vertical support member 6 at each of the four corners of the horizontal support frame 5. The electric actuator is mounted on the horizontal support frame 5, while the automatic adjustment component and the travel motor 4 are both mounted on the vertical support members 6. Each of the four vertical support members 6 has a travel wheel 7 at its bottom that matches the travel track 3, facilitating the movement of the docking trolley.

[0040] Specifically, the horizontal support frame 5 is a square frame, which includes two parallel first support members 8 and a second support member 9 perpendicular to the two first support members 8. The electric actuator is connected to the second support member 9 through a third support member 10 so that the electric actuator is mounted on the horizontal support frame 5.

[0041] Specifically, an I-beam 11 is welded onto the traveling track 3 and arranged along the entire length of the traveling track 3. The traveling wheel 7 is installed in the groove of the I-beam 11 and can move in the groove under the drive of the traveling motor 4.

[0042] Next, we will introduce the docking assembly. The docking assembly includes a connecting pipe and a connecting pipe 12 connected to the connecting pipe. The upper end of the connecting pipe is connected to the electric actuator, and its lower end passes through the automatic adjustment assembly. A connecting pipe valve 13 is provided on the connecting pipe, and the connecting pipe 12 is used to connect the connecting pipe and the gas-using equipment.

[0043] Specifically, the connector is a plug-in connector, which includes a main connector 14 and a fixing tube 15 fitted on the main connector 14. The fixing tube 15 is used for fixed installation on the automatic adjustment assembly.

[0044] Specifically, the connecting pipe 12 is installed on the upper part of the docking main pipe 14, and a return spring 16 is fitted on the docking main pipe 14. The two ends of the return spring 16 are fixedly connected to the connecting pipe 12 and the fixed pipe 15 respectively, so as to compress or stretch under the drive of the electric actuator, thereby causing the docking main pipe 14 to descend or rise.

[0045] Corresponding to the main gas supply pipe 14, a plurality of gas supply branch pipes 17 are arranged at intervals and extend vertically on the main gas supply pipe 2. The radial dimension of the gas supply branch pipe 17 is larger than that of the main gas supply pipe 14, and its upper end has a flared opening 19 for inserting the main gas supply pipe 14. A branch pipe valve 18 is provided on the gas supply branch pipe 17. Both the branch pipe valve 18 and the connecting pipe valve 13 are connected to the controller.

[0046] Next, the electric actuator assembly will be introduced. The electric actuator assembly includes an electric actuator 20, the output end of which is connected to the upper end of the docking main pipe 14. Positioners are installed on both the electric actuator 20 and the air supply branch pipe 17. The controller is connected to the positioner so that the docking trolley can be accurately positioned by the positioner to determine whether it is in a suitable air supply position.

[0047] Specifically, the electric actuator 20 is preset with a preset pressure value when the main pipe 14 is pressed. When the preset pressure value is reached when the main pipe 14 is connected to the gas supply branch pipe 17, the connecting pipe valve 13 and the branch pipe valve 18 are opened in sequence to supply gas to the gas-using equipment.

[0048] Finally, the automatic adjustment component is introduced. The automatic adjustment component is an automatic adjustment disc, which includes a main disc 21. The main disc 21 has a groove, and four adjustment discs 22 corresponding to the four sides of the main disc 21 are installed in the groove. The adjustment discs 22 are connected to the main disc 21 by adjustment springs 23, so that when the main pipe 14 is inserted into the air supply pipe 17, the horizontal position of the main pipe 14 can be adjusted by the compression or extension of the adjustment springs 23.

[0049] Specifically, the side of the adjusting disc 22 away from the adjusting spring 23 is provided with a quarter-circular arc-shaped notch that matches the fixing tube 15, so as to fix the fixing tube 15. Correspondingly, there is a circular opening at the corresponding position on the main disc 21, and the radius of the circular opening is larger than the radius of the arc-shaped notch.

[0050] Specifically, a fourth support member parallel to the first support member 8 is also provided on two adjacent vertical support members 6, and four connectors 24 are provided on the main plate 21. The main plate 21 is connected to the fourth support member through the connectors 24.

[0051] Specifically, connector 24 is a right-angled triangular pyramid.

[0052] Specifically, the first support member 8, the second support member 9, the third support member 10, the fourth support member, and the vertical support member 6 are all square steel pipes.

[0053] In addition, gas leak detection sensors 25 are installed on both the docking trolley and the docking branch pipe 17 to detect whether there is a natural gas leak. The gas leak detection sensors 25 are connected to the controller.

[0054] It should be noted that, Figure 4 This is an application diagram of the mobile automatic gas supply docking device provided by the present invention. The forward direction of the gas-using equipment is defined as moving from right to left. Figure 4 In the middle, the docking trolleys from right to left are docking trolley number 1 (26) and docking trolley number 2 (27), and the gas supply pipes from right to left are gas supply pipe number 1 (28), gas supply pipe number 2 (29), and gas supply pipe number 3 (30).

[0055] Furthermore, it should be noted that in this embodiment, the main gas supply pipeline, the track support frame, and the travel track all extend horizontally. In other embodiments, the main gas supply pipeline, the track support frame, and the travel track may also extend vertically. In this case, the positional relationship between the relevant structures on the travel track and the travel track is the same as the positional relationship between the relevant structures on the travel track and the travel track when the travel track extends horizontally, and will not be repeated here.

[0056] The working principle of the mobile gas supply automatic docking device provided by the present invention is as follows: the first docking trolley 26 and the second docking trolley 27 are respectively connected to the first gas supply branch pipe 28 and the second gas supply branch pipe 29.

[0057] When the gas-consuming equipment is running in a stationary state, docking trolley 26 No. 1 and docking trolley 27 simultaneously supply gas to the gas-consuming equipment;

[0058] As the gas-consuming equipment moves forward, the No. 1 docking trolley 26 maintains its gas supply to the equipment, and the branch valve 18 on the No. 2 gas supply branch pipe 29 is closed. Then, the docking main pipe 14 of the No. 2 docking trolley 27 disconnects from the No. 2 gas supply branch pipe 29 under the drive of the electric actuator 20. After disconnection, the travel motor 4 drives the No. 2 docking trolley 27 forward to the No. 3 gas supply branch pipe 31. When the controller receives a signal from the positioner indicating that the No. 2 docking trolley 27 is in a suitable gas supply position, the controller controls the electric actuator 20 to operate, driving the docking main pipe 14 of the No. 2 docking trolley 27 downwards until it is inserted into the No. 3 gas supply branch pipe. Within 30 seconds, during the insertion process, the automatic adjustment panel automatically adjusts the horizontal position of the fixed pipe 15 according to the position of the No. 3 gas supply branch pipe 30 to ensure that the docking main pipe 14 can be correctly docked with the No. 3 gas supply branch pipe 30. When the preset pressure value of the electric actuator 20 is reached, the docking pipe valve 13 and the gas supply valve 18 are opened in sequence under the control of the controller to supply gas to the gas-using equipment. Similarly, when the gas-using equipment continues to move forward, the No. 2 docking trolley 27 continues to supply gas to the gas-using equipment, and the No. 1 docking trolley 26 moves forward. The No. 1 docking trolley 26 and the No. 2 docking trolley 27 move forward alternately, thereby ensuring continuous gas supply to the moving gas-using equipment.

[0060] Its main difference from Example 1 is:

[0061] In Example 1, the number of docking trolleys is two.

[0062] In this embodiment, the number of docking trolleys is two or more.

[0063] Embodiment 3 of the mobile gas supply automatic docking device provided by the present invention:

[0064] Its main difference from Example 1 is:

[0065] In Example 1, the first support member, the second support member, the third support member, the fourth support member, and the vertical support member are all square steel pipes.

[0066] In this embodiment, the first support member, the second support member, the third support member, the fourth support member, and the vertical support member are angle steel, channel steel, I-beam steel, or H-beam steel.

[0067] Based on the above description in this specification, those skilled in the art will also understand that the following terms, such as "upper," "lower," "front," "rear," "left," "right," "width," "horizontal," "top," "bottom," "inner," and "outer," which indicate orientation or positional relationships, are based on the orientation or positional relationships shown in the accompanying drawings of this specification. They are only for the purpose of facilitating the explanation of the present invention and simplifying the description, and do not explicitly or implicitly suggest that the device or element involved must have the specific orientation, or be constructed and operated in a specific orientation. Therefore, the above-mentioned orientation or positional relationship terms should not be understood or interpreted as limitations on the present invention.
