Description

Technical Field

[0001] The utility model belongs to the technical field of welding and cutting tools, in particular to a fixing clamp for valve maintenance. Background Art

[0002] Valves need to be regularly inspected and maintained after daily work, and they need to be repaired when they are damaged. The valve repair requires cutting and welding. The damaged part is cut off with a cutting machine, and then the new accessories are welded to the original damaged part with a welding machine. One of the most common auxiliary tools for cutting and welding in valve repair is the fixing fixture, which can be used to position and clamp the valve to avoid position displacement during welding and cutting.

[0003] A Chinese patent application (or patent) with announcement number CN220093580U discloses a positioning device for valve welding, including a mounting shell, a mounting seat is fixed to the bottom of the mounting shell, a mounting hole is opened on the top of the mounting shell, and a quick positioning device is installed on the inner bottom wall of the mounting shell; the device is provided with a quick positioning device, when positioning the valve welding, the valve is placed in the corresponding positioning seat, and then the positioning sleeve is loosened to allow the valve to be inserted into the positioning groove corresponding to the positioning sleeve and the positioning seat, the positioning operation is simple, and the purpose of quick installation and positioning is achieved, and when taking and carrying the device, only the handle plate needs to be held to carry and move it, and it is relatively easy to use; the device is provided with a stabilizing device, the support frame on the top of the limit pad can drive the support frame and the support sleeve to move at the same time, and the support sleeve can be fitted on the outside of the corresponding welding positioning part, which plays a role of auxiliary reinforcement and improves the stability of the valve welding positioning.

[0004] The above-mentioned positioning device for valve welding has positioning grooves on the outer sides of the positioning seat and the positioning sleeve in its quick positioning device. The positioning grooves are semicircular in structure and are used to clamp the valves. However, valves of different specifications and types have different valve bodies, and the notch of the semicircular positioning groove is not adjustable, so it can only be adapted to valves of specific specifications and types, thus having a narrow application range. In addition, a quick positioning device for clamping the valve is provided on its mounting shell, and a stabilizing device for auxiliary support is provided at the front end of the quick positioning device. When cutting or welding the valve clamped therein, more sparks will be generated, and some of the sparks will directly impact the outer wall of the positioning device, thus having an adverse effect on the positioning device. To this end, we provide a fixing fixture for valve maintenance to solve the above-mentioned problems. Utility Model Content

DETAILED DESCRIPTION

[0026] 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.

[0027] Example 1

[0028] See also Figure 1-4 The utility model is a fixing fixture for valve maintenance, including a base 1 and support plates 2 arranged at both ends thereof, and a fixing component 3 is also installed on the support plate 2. The fixing component 3 can be inserted into the valve port at both ends of the valve and abut against the inner wall of the valve port through an abutment 303.

[0029] Specifically, support plates 2 are fixedly installed at both ends of the base 1, and threaded sleeves 201 are embedded in the support plates 2. The support plates 2 are threadedly connected to the studs 301 in the fixing assembly 3 through the threaded sleeves 201. An air pump box 302 is installed at the end of the stud 301, and an abutment 303 is installed on the outer wall of the air pump box 302, wherein the abutment 303 includes a pneumatic rod 303a installed on the outer wall of the air pump box 302, and the axial end of the pneumatic rod 303a is threadedly connected to an abutment block 303c.

[0030] Furthermore, mounting grooves 101 for mounting the support plate 2 are provided on the upper side walls at both ends of the base 1, a turntable 301a is installed on one side axial end of the stud 301, and a mounting hole 301b is provided on the other side axial end of the stud 301, the stud 301 is connected to the connecting column 302b through the mounting hole 301b, and the end of the connecting column 302b is welded to the air pump box 302, an air pump is arranged inside the air pump box 302, and the air pump is connected to the pneumatic rod 303a through an air pipe, and at the same time, side holes 302a are provided on the outer walls of the four sides of the air pump box 302, and the side holes 302a are threadedly connected to the rod frame 303b, and the pneumatic rod 303a is clamped inside the rod frame 303b, and at the same time, an anti-slip pad 303d is bonded to the outer wall of the abutment block 303c.

[0031] The operation process of this embodiment is as follows: when in use, align the valve port of the valve to be repaired with the abutment 303, and then hold the turntable 301a and rotate it, so that the abutment 303 on the end of the stud 301 extends into the valve port on one side of the valve, and the fixing component 3 on the other side of the base 1 is operated reciprocally so that the abutment 303 on the two fixing components 3 are inserted into the valve port of the valve, and then the pneumatic rod 303a on the abutment 303 is started. At this time, the pneumatic rod 303a extends out, and the abutment block 303c on the shaft end thereof abuts against the inner wall of the valve port of the valve through the anti-slip pad 303d, thereby completing the fixation of the valve.

[0032] Example 2

[0033] See also Figure 5 On the basis of Example 1, a blocking plate 4 is further provided. Through the absorption component 5 on the rear side wall of the blocking plate 4, negative pressure can be generated on the wind groove 402 in the blocking plate 4, thereby achieving the effect of directional absorption of sparks generated when cutting or welding the valve.

[0034] Specifically, a wind slot 402 is opened on the blocking plate 4, and a metal mesh 403 is embedded in the wind slot 402. The rear side wall of the wind slot 402 is detachably fixedly connected to the absorption plate 501 in the absorption component 5, and the other end of the absorption plate 501 is connected to the air outlet of the negative pressure fan 503 through the connecting pipe 502.

[0036] The operation process of this embodiment is as follows: when in use, the negative pressure fan 503 works, and it can input the negative pressure into the absorption plate 501 through the connecting pipe 502. Since the absorption plate 501 opens toward the wind slot 402, suction is formed at the position of the wind slot 402, thereby absorbing the sparks generated during cutting or welding.
