Technical Field
[0001] This utility model relates to the field of gas emergency rescue engineering technology, and in particular to a pipeline support for a gas emergency rescue engineering vehicle. Background Technology
[0002] Gas pipelines are transportation systems made of materials such as steel and plastic pipes. They are mainly used to transport combustible gases such as natural gas and coal gas, and are an important part of urban infrastructure. When gas pipelines are damaged by external forces, they need to be supported by pipeline support brackets on gas emergency repair vehicles to facilitate repairs.
[0003] For example, Chinese patent document CN220980509U discloses a municipal pipeline support base, belonging to the field of pipeline support technology. It includes a base; two movable frames are slidably mounted on the base, and sliding plates are slidably mounted vertically within the movable frames; a connecting cylinder and a placement frame are sequentially fixedly connected upwards to the sliding plates; a rotating motor is mounted on the placement frame, and a rotating plate controlled by the rotating motor is located within the placement frame; a fixed frame is fixedly connected to the rotating frame, and a fixed half-cylinder is fixedly mounted within the fixed frame; a pressing half-cylinder corresponding to the fixed half-cylinder is slidably mounted vertically within the fixed frame. By using a rotating motor to control the rotation of the entire pipeline installation structure and to drive the fixing mechanism to rotate synchronously, the problem of inconvenience in supporting and fixing pipelines at different installation angles in existing technologies can be solved.
[0004] The clamping half-cylinder and the fixing half-cylinder of the above-mentioned pipe support are of fixed size. During use, they can only clamp and fix pipes of a specified size, and are not convenient for use on pipes of other sizes. Utility Model Content
[0005] The purpose of this utility model is to provide a pipeline support for a gas emergency rescue vehicle to solve the problems and defects mentioned in the background art.
[0006] To achieve the above objectives, this utility model provides the following technical solution: a gas emergency rescue vehicle pipeline support base, comprising a hollow base, a hollow column slidably installed on the inner side of the hollow base, the top end of the hollow column extending above the hollow base and fixedly installed with a housing, a gas pipeline placed on the top outer wall of the housing, clamping plates A and B provided on the top of the housing, and an electric push rod hinged to the outer wall of the hollow column, the free end of the electric push rod being fixedly installed to the bottom outer wall of the housing, a rotating structure installed on the housing, which, through clamping plates A, clamping plates B, and the rotating structure, is used to clamp and fix the gas pipeline to the top of the housing, and a lifting structure installed on the hollow base and the hollow column, which is used to adjust the height of the gas pipeline.
[0007] Preferably, the rotating structure includes a motor A, a bidirectional worm gear, a fixed shaft, and a worm wheel. The motor A is fixedly installed on one outer wall of the housing, and the bidirectional worm gear is rotatably installed on both inner walls of the housing. The output shaft of the motor A is fixedly installed at one end of the bidirectional worm gear. The fixed shaft is fixedly installed on the front and rear inner walls of the housing, and the worm wheel is rotatably installed on the outer wall of the fixed shaft. There are two fixed shafts and two worm wheels, which are arranged symmetrically on the left and right. Both worm wheels mesh with the bidirectional worm gear, so that clamping plate A and clamping plate B move synchronously in opposite directions. This allows for flexible clamping of gas pipes of different diameters without the need to replace adapter parts, thus expanding the compatibility range.
[0008] Preferably, the lifting structure includes a threaded rod, a motor B, a rotating shaft, a bevel gear A, a bevel gear B, and a rod plate. The rod plate is fixedly installed on the inner wall of the hollow base, the threaded rod is rotatably installed on the rod plate, the motor B is fixedly installed on one outer wall of the hollow base, the rotating shaft is rotatably installed on both inner walls of the hollow base, the bevel gear A is fixedly installed on the outer wall of the rotating shaft, and the bevel gear B is fixedly installed at the bottom end of the threaded rod. The bevel gear B meshes with the bevel gear A, which can precisely adjust the height of the gas pipeline. With the help of an electric push rod, the pipeline installation angle can be adjusted to meet the height and angle requirements in different emergency rescue scenarios, reducing the tediousness and error of manual adjustment.
[0009] Preferably, the top of the chassis has an opening for movement, and the bottom ends of clamping plates A and B pass through the opening and are fixedly installed to the outer walls of the two worm gears respectively.
[0010] Preferably, the bevel gear A meshes with the bevel gear B, and the transmission ratio between the bevel gear A and the bevel gear B is 1:1.
[0011] Preferably, both clamping plate A and clamping plate B are provided with cross grooves, and clamping plate A and clamping plate B are arranged in a cross manner.
[0012] Preferably, rubber pads are affixed to the top outer wall of the chassis and the adjacent side walls of clamping plate A and clamping plate B. This can prevent damage to the outer wall of the pipe during clamping, and also enhance friction to prevent the pipe from sliding, thus ensuring the stability and safety of the pipe fixation during emergency operations.
[0013] Compared with the prior art, the beneficial effects of this utility model are: The gas emergency repair vehicle's pipeline support base uses a rotating structure driven by motor A to rotate a bidirectional worm gear, which in turn drives two worm wheels to rotate in opposite directions. This causes the intersecting clamps A and B, with their cross grooves, to move synchronously in opposite directions, allowing for flexible clamping of gas pipelines of different diameters without the need to replace adapter parts, thus broadening its compatibility. Simultaneously, the lifting structure, using motor B, bevel gear transmission, and threaded rod, can precisely adjust the height of the gas pipeline. Combined with an electric push rod, the pipeline installation angle can be adjusted to meet the height and angle requirements of different emergency repair scenarios, reducing the tediousness and errors of manual adjustments.

[0017] Please see Figure 1-3 This utility model provides a technical solution: a gas emergency rescue engineering vehicle pipeline support base, including a hollow base 1, a hollow column 2 slidably installed on the inner side of the hollow base 1, the top of the hollow column 2 extending above the hollow base 1 and fixedly installed with a housing 3, a gas pipeline 4 placed on the top outer wall of the housing 3, and clamping plates A5 and B6 provided on the top of the housing 3, and also includes an electric push rod 11 hinged to the outer wall of the hollow column 2, the free end of the electric push rod 11 being fixedly installed to the bottom outer wall of the housing 3.

There are two fixed shafts 9 and two worm wheels 10, which are arranged symmetrically on the left and right. Both worm wheels 10 mesh with the bidirectional worm gear 8. When the motor A7 is started, the output shaft of the motor A7 drives the bidirectional worm gear 8 to rotate. The rotation of the bidirectional worm gear 8 drives the two worm wheels 10, clamping plates A5 and B6 to rotate in opposite directions. This allows for flexible clamping of gas pipes of different diameters without the need to replace adapter parts, thus expanding the range of compatibility.
[0019] Furthermore, the lifting structure includes a threaded rod 12, a motor B13, a rotating shaft 14, a bevel gear A15, a bevel gear B16, and a rod plate 17.

[0021] Furthermore, bevel gear A15 meshes with bevel gear B16, and the transmission ratio between bevel gear A15 and bevel gear B16 is 1:1.
[0022] Furthermore, both clamping plate A5 and clamping plate B6 are provided with cross grooves, and clamping plate A5 and clamping plate B6 are arranged in a cross manner.
[0023] Furthermore, rubber pads are affixed to the top outer wall of the chassis 3 and the adjacent side walls of clamping plates A5 and B6. This can prevent damage to the outer wall of the pipe during clamping, and also enhance friction to prevent the pipe from sliding, ensuring the stability and safety of the pipe fixation during emergency operations.
[0024] Working Principle: The device is installed on an engineering vehicle. When the gas pipeline needs replacement or maintenance, the gas pipeline 4 is placed on top of the casing 3, and driven to be positioned between clamping plates A5 and B6. The controller starts motor A7, whose output shaft drives a bidirectional worm gear 8 to rotate. The rotation of the bidirectional worm gear 8 drives the two worm wheels 10, clamping plates A5 and B6 to rotate in opposite directions, thus clamping and fixing the gas pipeline 4 to the top of the casing 3. The engineering vehicle then moves the gas pipeline to the designated area, and then the electric motor is started... The output shaft of motor B13 drives shaft 14 and bevel gear A15 to rotate. The rotation of bevel gear A15 drives bevel gear B16 and threaded rod 12 to rotate. The rotation of threaded rod 12 drives hollow column 2, housing 3 and gas pipeline 4 to rise, and moves gas pipeline 4 to the assembly position, so that gas pipeline 4 can be installed. By activating electric push rod 11, the output shaft of electric push rod 11 can push housing 3 up or down, and can drive housing 3 and gas pipeline 4 to tilt back and forth, and adjust the installation angle of gas pipeline 4.
