[0023] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0024] See also Figure 1-4 The utility model provides a technical solution: an auxiliary installation device for a flame arrester, comprising: a support plate 1; a positioning member 2 is symmetrically and liftably installed at both ends of the support plate 1, and a lifting rod 4 is fixedly connected to the side of the positioning member 2, and the lifting rod 4 penetrates the support plate 1 and is slidably connected to the support plate 1; a distance-adjusting plate 6 is symmetrically arranged above the support plate 1, and a driving part for driving the distance-adjusting plate 6 to move is arranged in the middle of the support plate 1, and a clamping and fixing plate 7 is arranged at the end of the clamping and fixing plate 7, and a clamping groove 16 is opened at the end of the clamping and fixing plate 7 for clamping and fixing the flame arrester; a supporting mechanism is arranged at the bottom of the support plate 1, and the supporting mechanism includes a supporting leg with adjustable length.

[0025] It should be noted that the utility model adjusts the spacing between the two clamping and fixing plates 7 according to the length of the flame arrester, and then fixes the position of the clamping and fixing plates 7 by means of 12 clamping and fixing plates 7, and then places the flame arrester in the middle of the two adjustable distance plates 6, and drives the two adjustable distance plates 6 to move toward the middle of the support plate 1 at the same time by means of the driving part, so that the flame arrester is clamped and fixed by means of the clamping and fixing plates 7, and the support assembly of the support plate 1 is matched according to the installation situation so that the support plate 1 is in a horizontal or vertical state, and the height of the support plate 1 is adjusted by means of the supporting legs, and the positioning member 2 is first brought into contact with the pipeline to be docked, so as to preliminarily position the flame arrester and the pipeline, and ensure that the axes of the two are on the plane, so as to facilitate the subsequent alignment and installation.

[0026] like Figure 1 , 4 As shown, lifting holes 3 are provided at both ends of the support plate 1, the positioning member 2 is slidably connected to the lifting holes 3, a return spring 5 is sleeved on the outside of the lifting rod 4 and between the positioning member 2 and the support plate 1, and the positioning member 2 and the clamping groove 16 are both V-shaped structures.

[0027] It should be noted that, in the utility model, the pipeline is embedded in the V-shaped structure and cooperates with the groove wall. Placing the pipeline in the V-shaped structure can realize the positioning of the pipeline in a specific position. The V-shaped structure provides a clear position and direction, so that the pipeline can be accurately installed and positioned at the desired position. The V-shaped structure allows the flame arrester to be clamped and fixed inside it to prevent the flame arrester from shaking or shifting during operation. Under the action of the reset spring 5, the positioning member 2 is under the elastic force of the reset spring 5. The height of the reset spring 5 is higher than the height of the distance adjusting plate 6. When installing the flame arrester, the positioning member 2 first contacts the outer wall of the docking pipeline, so as to achieve accurate positioning of the pipeline axis. The positioning member 2 can be effectively contacted with the pipeline in two directions, so that it is more convenient to determine the position of the axis, and the support plate 1 is pushed along the lifting rod 4, so that the positioning member 2 compresses the reset spring 5, so that the flame arrester is docked with the axis, which is convenient for installation.

[0028] like Figure 1 , 2 As shown in Figure 3, a movable slide groove 8 is opened in the middle of the support plate 1, and the driving part includes two movable sliders 15 symmetrically slidably arranged inside the movable slide groove 8. The middle part of the movable slide groove 8 is threadedly connected to the bidirectional screw rod 9, and the movable slider 15 is threadedly connected to the bidirectional screw rod 9. The movable slider 15 is fixedly connected to the corresponding distance adjusting plate 6, and both ends of the distance adjusting plate 6 are slidably connected to the limit rod 10, the clamping fixing plate 7 is fixedly connected to the limit rod 10, and the top of the distance adjusting plate 6 is threadedly connected with a positioning screw 17 for fixing the limit rod 10.

[0029] It should be noted that the bidirectional screw rod 9 of the utility model is also called a bidirectional screw rod with positive and negative teeth or a bidirectional ball screw, and its characteristic is that the threads at both ends of the screw rod are rotated in opposite directions, that is, one end is left-handed and the other end is right-handed. When the screw rod rotates, it can drive the two nuts to move in opposite directions at the same time, so that the distance adjustment plate 6 moves toward the middle by rotating the bidirectional screw rod 9, so as to clamp and fix the flame arrester, and make the axis of the flame arrester and the center line of the support plate 1 and the positioning member 2 in the same plane, so as to facilitate the matching and positioning of the flame arrester and the pipeline, and the position of the limit rod 10 is limited by the tightness of the positioning screw 17, so that it can be fixed for flame arresters of different lengths.

[0030] like Figure 3 , 4 As shown, the support leg includes a support screw sleeve 13 and a lifting threaded rod 12 threadedly connected to the inside of the support screw sleeve 13, the top of the lifting threaded rod 12 is threadedly connected to a connecting support seat 11, and the connecting support seat 11 is fixedly connected to the support plate 1. The support mechanism also includes a base plate 14, which is rotatably connected to the support screw sleeve 13, and a universal wheel is installed at the bottom of the base plate 14.

[0031] It should be noted that when the utility model needs to splice the flame arrester with the horizontal pipe, the lifting threaded rod 12 is threadedly connected to the four corners of the bottom of the support plate 1, and the lifting threaded rod 12 is rotated inside the support screw sleeve 13. Under the action of the thread, the height of the lifting threaded rod 12 is adjusted to adjust the height of the flame arrester. When the flame arrester needs to be installed vertically, the flame arrester is installed on the outside of the support plate 1, and the support plate 1 is installed vertically with the lifting threaded rod 12, such as Figure 3 , so that the flame arrester is in a vertical state, so that it can be spliced ​​and installed with the pipeline.

[0032] In the description of the present invention, it should be understood that the terms "coaxial", "bottom", "one end", "top", "middle", "the other end", "upper", "one side", "top", "inside", "front", "center", "both ends" and the like indicate orientations or positional relationships based on the orientations or positional relationships shown in the accompanying drawings, and are only for the convenience of describing the present invention and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, be constructed and operated in a specific orientation, and therefore should not be understood as a limitation on the present invention.

[0033] In addition, the terms "first", "second", "third" and "fourth" are used for descriptive purposes only and are not to be understood as indicating or implying relative importance or implicitly indicating the number of technical features indicated. Thus, the features defined as "first", "second", "third" and "fourth" may explicitly or implicitly include at least one of such features.
