Description

Technical Field

[0001] This utility model relates to the field of gas pipeline maintenance technology, and in particular to a support tool for supporting the gas branch pipe in front of the gas meter during maintenance. Background Technology

[0002] In the existing process of repairing the branch pipes before the indoor gas meter, gas industry workers commonly use traditional tools such as adjustable wrenches and pipe wrenches.

[0003] When there are many indoor gas branch pipe elbows installed, two sets of tools are often needed to prevent the elbows from loosening during maintenance. One set of pipe wrenches is used for fixing and supporting, and is clamped onto the first set of threaded external pipe fittings in front of the part to be repaired. The other set of pipe wrenches or wrenches is fixed on the part to be repaired to apply force, thereby avoiding the force being transmitted to parts that do not need to be repaired or replaced, which could cause the threads to loosen and leak gas, increasing the amount of maintenance and maintenance time.

[0004] The above-described work process reveals the following shortcomings in actual operation. First, using two tools simultaneously requires adjusting the pipe wrench to the appropriate opening size. This necessitates a high degree of precision and skill to minimize the risk of tool slippage or loss, placing significant demands on the operator's skill level. Second, since most operators are right-handed, if the repair scenario requires the left hand to operate the pipe wrench for fixing the pipe fitting while the right hand operates the wrench for turning, and the tool slips due to an unsuitable opening size, adjusting with the left hand is often time-consuming and laborious. Switching back to the right hand for adjustment requires removing the other tool, significantly prolonging the operation time.

[0005] Therefore, how to quickly eliminate safety hazards during the maintenance of gas meter pipelines, ensure customer gas safety, reduce the risk of slippage and detachment, improve work efficiency, and be more user-friendly for the operator's non-dominant hand has become a technical problem that urgently needs to be solved by those skilled in the art. Utility Model Content

[0006] In view of the above-mentioned deficiencies of the prior art, this utility model provides a support tool for holding the gas branch pipe in front of the gas meter during maintenance. The purpose is to quickly eliminate safety hazards during the maintenance of the gas pipeline in front of the gas meter, ensure the gas safety of customers, reduce the risk of slippage and fall, improve work efficiency, and be more friendly to the operator's non-dominant hand.

[0007] To achieve the above objectives, this utility model discloses a support tool for holding the gas branch pipe in front of the gas meter during maintenance, including a clamp-type clamp.

[0008] The clamp-type fixture includes three arc-shaped blades arranged around the axis of the gas branch pipe to be clamped;

[0009] The sum of the central angles of the three arc-shaped blades is no greater than 360 degrees and no less than 210 degrees. They are connected in a hinged manner, and the concave surfaces facing the gas branch pipe to be clamped are provided with anti-slip patterns or anti-slip layers.

[0010] The two hinged rotation axes of the three arc-shaped blades are parallel to the axis of the gas branch pipe to be clamped.

[0011] Of the three arc-shaped leaf pieces that are connected in sequence by hinges, the two end leaf pieces located at both ends are driven by a push rod hinge mechanism to rotate relative to the middle leaf piece located between the two end leaf pieces.

[0012] Preferably, the outer side of the middle leaf facing away from the gas branch pipe to be clamped is provided with a handle;

[0013] The handle is a strip-shaped rod, with its length direction perpendicular to the axis of the gas branch pipe to be clamped, and the push rod hinge mechanism is provided on the side perpendicular to the axis of the gas branch pipe to be clamped.

[0014] The push-rod hinge mechanism includes a C-shaped elastic element that is connected to the handle in a sliding pair;

[0015] The center of the C-shaped elastic element is connected to the handle in a sliding joint, allowing it to reciprocate along the length of the handle. Both ends are connected to the outer surfaces of the two end plates facing away from the gas branch pipe to be clamped in a rotary joint.

[0016] More preferably, the side of the handle perpendicular to the axis of the gas branch pipe to be clamped includes a groove extending along the length direction.

[0017] The slide groove is equipped with a slider connected in a movable pair;

[0018] The slider has two or more slots along the length of the handle that can engage the C-shaped elastic element.

[0019] More preferably, the C-shaped elastic element is made of spring steel.

[0020] More preferably, the handle is provided with a weight-reducing groove.

[0021] Preferably, the central angle corresponding to the intermediate page is not greater than 180 degrees and not less than 150 degrees; the central angle corresponding to each end page is not greater than 90 degrees and not less than 60 degrees.

[0022] Preferably, both of the ends of the blades that can be closed are provided with flanges extending outward in the normal direction of the gas branch pipe to be clamped; the two flanges are fastened together by detachable fasteners.

[0023] More preferably, the fastener is a bolt or a C-clamp.

[0024] The beneficial effects of this utility model are:

[0025] The application of this utility model can quickly eliminate safety hazards in the maintenance of gas meter pipelines, ensure the gas safety of customers, reduce the risk of slippage and detachment, improve work efficiency, and is more friendly to the operator's non-dominant hand.

[0026] This invention not only improves the efficiency of repairing the branch pipe before the indoor gas meter and quickly eliminates safety hazards, but also reduces the workload of workers, replacing traditional tools to quickly clamp the branch pipe before the indoor gas meter, providing practitioners with a new repair method.

[0027] The application of this utility model can reduce the labor intensity of replacing the branch pipe before the indoor gas meter and improve the efficiency of repairing the branch pipe before the indoor gas meter.

[0028] This invention can be well and efficiently matched with standard DN20 diameter pipes for clamping, avoiding the drawbacks of traditional tools that require frequent adjustment of the jaw opening size, thus saving time.

[0029] This invention can reduce the need for operators to use their non-dominant hand for fine operations.

[0030] This invention can adapt to the needs of different gas usage locations and can work well in various conditions such as rusted, dirty, greasy, and dusty pipes, reducing the operational risks caused by slippage and tool drop.

[0037] Example

[0038] like Figures 1 to 5 As shown, a support tool for holding the gas branch pipe in front of the gas meter during maintenance includes a clamp-type clamp 1;

[0039] The clamp-type fixture 1 includes three arc-shaped blades 11 arranged around the axis of the gas branch pipe 9 to be clamped;

[0040] The sum of the central angles of the three arc-shaped blades 11 is not greater than 360 degrees and not less than 210 degrees. They are connected in a hinged manner and the concave surfaces facing the gas branch pipe 9 to be clamped are provided with anti-slip patterns or anti-slip layers 12.

[0041] The two hinged rotation axes of the three arc-shaped blades 11 are parallel to the axis of the gas branch pipe 9 to be clamped.

[0042] Of the three arc-shaped leaf pieces 11 connected in sequence by hinges, the two end leaf pieces located at both ends are driven by the push rod hinge mechanism 3 to rotate relative to the middle leaf piece located between the two end leaf pieces.

[0043] In some embodiments, a handle 2 is provided on the outer side of the middle leaf facing away from the gas branch pipe 9 to be clamped;

[0044] The handle 2 is a strip-shaped rod, with its length direction perpendicular to the axis of the gas branch pipe 9 to be clamped, and a push rod hinge mechanism 3 is provided on the side perpendicular to the axis of the gas branch pipe 9 to be clamped.

[0045] The push-rod hinge mechanism 3 includes a C-shaped elastic element 31 that is connected to the handle 2 in a sliding joint;

[0046] The center of the C-shaped elastic element 31 is connected to the handle 2 in a sliding joint, and can move back and forth along the length of the handle 2. Its two ends are respectively connected to the outer side of the two end plates facing away from the gas branch pipe 9 to be clamped in a rotary joint.

[0047] In some embodiments, the side of the handle 2 perpendicular to the axis of the gas branch pipe 9 to be clamped includes a groove 21 extending along the length direction.

[0048] The slide groove 21 is provided with a slider 22 connected to it in a sliding pair;

[0049] The slider 22 has two or more slots 23 along the length of the handle 2 that can engage the C-shaped elastic element 31.

[0050] In some embodiments, the C-shaped elastic element 31 is made of spring steel.

[0051] In some embodiments, the handle 2 is provided with a weight-reducing groove 24.

[0052] In some embodiments, the central angle corresponding to the middle page is not greater than 180 degrees and not less than 150 degrees; the central angle corresponding to each end page is not greater than 90 degrees and not less than 60 degrees.

[0053] In some embodiments, the sides of the two end flaps that can be closed are provided with flanges 13 extending outward in the normal direction of the gas branch pipe 9 to be clamped; the two flanges 13 are fastened together by detachable fasteners.

[0054] In some embodiments, the fastener is a bolt or a C-clamp.

[0055] In practical applications, the clamp-type fixture 1 is made of CRV chromium vanadium steel commonly used in tools. The inner radius is approximately the standard outer diameter (26.9mm) of a DN20 pipe fitting (selecting the galvanized steel fitting with the highest usage ratio), which can be well matched with the outer diameter of the gas branch pipe 9 to be clamped, i.e., the DN20 pipe branch pipe in front of the gas meter.

[0056] like Figure 1 As shown, the concave surfaces of the three arc-shaped blades 11 facing the gas branch pipe 9 to be clamped are all provided with anti-slip patterns or anti-slip layers 12.

[0057] Anti-slip patterns are usually vertical triangular horizontal stripes that increase friction to improve bite performance.

[0058] The handle 2 is 250mm long and is made of aluminum alloy or aluminum-magnesium alloy to reduce weight. It is connected to the clamp 1 via a threaded connection.

[0059] The C-shaped elastic element 31 ensures that the force exerted by the operator when using support tools and maintenance tools during maintenance can cancel each other out, ensuring that the normal pipeline is not affected by external forces.

[0060] In practical use, the specific usage method is as follows: Figure 5 As shown, if a leak is found in the valve before the indoor gas meter or the last set of DN20 threaded pipe fittings before the branch meter, repair work is required.

[0061] After applying this utility model, the operator can place this utility model against the section of pipe in front of the gas branch pipe 9 to be clamped with one hand. At this time, the clamping clamp 1 tool is in the open state. When the gas branch pipe 9 to be clamped is pushed into the clamping clamp 1, the connecting rod hinge mechanism 3 can be pushed to make the C-shaped elastic element 31 clamp the clamping clamp 1 tightly.

[0062] After the gas branch pipe 9 to be clamped is secured in this utility model, the operator uses pipe wrenches, wrenches, and other corresponding tools with their other hand to repair the corresponding pipe fittings, valves, etc.

[0063] Through the aforementioned technical means, the application of this utility model can replace traditional tools without requiring adjustment of the opening size. Whether disassembling or tightening pipe fittings, the clamping support tool can adapt to corresponding pulling or pushing forces, fixing pipe fittings that do not require maintenance and preventing force transmission.

[0064] The preferred embodiments of this utility model have been described in detail above. It should be understood that those skilled in the art can make numerous modifications and variations based on the concept of this utility model without creative effort. Therefore, all technical solutions that can be obtained by those skilled in the art based on the concept of this utility model through logical analysis, reasoning, or limited experimentation on the basis of existing technology should be within the scope of protection defined by the claims.
