[0026] See also Figures 1 to 4 In the utility model, the auxiliary support and positioning device for the gas engineering pipeline includes a support plate 100, a support mechanism 200, an adjustment component 300 and a limit mechanism 400.

[0027] The supporting mechanism 200 includes a first supporting arm 201 and a second supporting arm 202 arranged above the support plate 100, and a connecting shaft 203 is hingedly installed between the first supporting arm 201 and the second supporting arm 202 and cross-arranged to form an "X" shape. The first supporting arm 201 and the second supporting arm 202 are used to support the outer diameter of the gas pipeline; the adjusting mechanism is arranged on the top of the support plate 100 and is used to adjust the angle between the first supporting arm 201 and the second supporting arm 202 to adapt to gas pipelines of different sizes; the limiting mechanism 400 is provided in two groups and is respectively connected to the first supporting arm 201 and the second supporting arm 202, and the two groups of limiting mechanisms 400 can rotate around the first supporting arm 201 and the second supporting arm 202 respectively to press and limit the supported gas pipeline.

[0028] In this embodiment, preferably, the support mechanism 200 further includes a slide rail 204 fixedly connected to the front and rear sides of the top of the support plate 100, and the bottom ends of the first support arm 201 and the second support arm 202 are both hingedly mounted with a slide seat 205, and the slide seat 205 can be slidably arranged above the corresponding slide rail 204;

[0029] Specifically, when the adjustment assembly 300 moves the connecting shaft 203 up and down, the slide seat 205 at the bottom of the first support arm 201 and the second support arm 202 can slide along the slide rail 204, thereby changing the angle between the first support arm 201 and the second support arm 202 to adapt to supporting gas pipelines of different sizes.

[0030] In this embodiment, preferably, the adjustment assembly 300 includes a bidirectional screw 301 rotatably arranged above the support plate 100, two moving blocks 302 spaced apart along the length direction of the bidirectional screw 301 are threadedly connected on the outer wall of the bidirectional screw 301, a connecting piece 303 is fixedly sleeved on the outer wall of the connecting shaft 203, and a connecting rod 304 is hingedly installed between the tops of the two moving blocks 302 and the connecting piece 303;

[0031] Specifically, when the bidirectional screw 301 rotates, the two moving blocks 302 move relative to or away from each other through thread transmission, and then the connecting piece 303 is pushed by the connecting rod 304 to move the connecting shaft 203 upward or downward.

[0032] In this embodiment, preferably, the two groups of limiting mechanisms 400 both include connecting arms 401, and the two connecting arms 401 are respectively fixedly connected to the top ends of the first support arm 201 and the second support arm 202, and the front side of each connecting arm 401 is fixedly connected to a connecting plate 402, and the front side of each connecting arm 401 is rotatably provided with a rotating arm 403 through an axle pin, and the front side of the rotating arm 403 is provided with a round tooth groove 404, and the inner side of the connecting plate 402 is provided with a gear 405 that can be inserted into the round tooth groove 404 and meshed with the round tooth groove 404, and the front side of the gear 405 is fixedly connected to a sliding rod 406 that penetrates the connecting plate 402, and a spring 407 that is sleeved on the outside of the sliding rod 406 is fixedly connected between the front side of the gear 405 and the connecting plate 402;

[0033] Specifically, when limiting the position of the gas pipeline placed between the first support arm 201 and the second support arm 202, the sliding rod 406 is pulled to separate the gear 405 and the round tooth groove 404 and squeeze the spring 407, so that the rotating arm 403 can be rotated to a certain angle, and by loosening the sliding rod 406, the elastic force of the spring 407 pushes the gear 405 to return to the round tooth groove 404 and mesh with the round tooth groove 404, thereby limiting the rotating arm 403 so that it cannot rotate.

[0034] In this embodiment, preferably, the front end of the slide bar 406 is fixedly connected with a lever 408 penetrating the slide bar 406, and the cross section of the slide bar 406 is a cross-shaped structure;

[0035] Specifically, the slide bar 406 can be easily pulled by the lever 408, and the slide bar 406 with a cross-shaped cross section can only move forward and backward, so that the gear 405 will not have a tendency to rotate in the circumferential direction.

[0037] Specifically, after the gas pipeline is supported and positioned, if the gas pipeline needs to be rotated, the gas pipeline rolls between the supporting roller 206 and the limiting roller 409 to reduce the friction resistance of the gas pipeline and facilitate workers to roll the gas pipeline.

[0039] Specifically, the rotation of the bidirectional screw rod 301 can be conveniently adjusted by the hand crank 305 .

[0040] The working principle and use process of this utility model:

[0041] According to the different diameters of the gas pipeline, it is necessary to adjust the angle between the first support arm 201 and the second support arm 202. The bidirectional screw 301 is controlled to rotate by the hand crank 305 to drive the two moving blocks 302 to move relative to or away from each other. The moving block 302 pushes the connecting piece 303 through the connecting rod 304 to move the connecting shaft 203 upward or downward. The movement of the connecting shaft 203 causes the slide seat 205 at the bottom of the first support arm 201 and the second support arm 202 to slide along the slide rail 204, thereby changing the angle between the first support arm 201 and the second support arm 202 to adapt to supporting gas pipelines of different sizes, thereby supporting pipelines of different diameters, and effectively expanding the scope of application.

[0042] After the gas pipeline is placed between the first support arm 201 and the second support arm 202, the gear 405 is pulled out of the circular tooth groove 404 by pulling the sliding rod 406 through the lever 408, and the rotating arm 403 is rotated to make the limiting roller 409 at its upper end contact the gas pipeline. The lever 408 is released to make the gear 405 reset and engage into the circular tooth groove 404 under the elastic force of the spring 407, so that the rotating arm 403 can be limited and made to fit on the gas pipeline to avoid the pipeline falling when adjusting the gas pipeline.

[0043] The electronic components and modules used in the content of this utility model can all be parts that are commonly used in the market and can realize the specific functions in this case, and the specific models and sizes can be selected and adjusted according to actual needs. The electronic components and modules are all connected to an external power supply and a control switch for use. Their specific circuit connection methods and methods of use are commonly used public technologies and will not be elaborated on here.

[0044] The above is only a preferred specific implementation of the utility model; however, the protection scope of the utility model is not limited thereto. Any technician familiar with the technical field can make equivalent replacements or changes according to the technical solution and improved ideas of the utility model within the technical scope disclosed by the utility model, which should be included in the protection scope of the utility model.
