Description

Technical Field

[0001] The utility model relates to the technical field of gas pipelines, and particularly relates to a vertical gas pipeline supporting device. Background Art

[0002] The statements herein only provide the background art related to the utility model, and do not necessarily constitute the prior art.

[0003] High-rise buildings rely on gas risers to supply gas to each floor for use. Currently, most of the vertically installed gas risers are installed on the wall by tightening the pipe wall with pipe clamps (also called pipe codes, hose clamps), and rely on the tangential and transverse frictional forces between the pipe clamps and the pipe wall to fix the gas riser. Among them, the tangential frictional force (i.e., the frictional force in the vertical direction) bears the main vertical gravity of the gas riser, and the supporting capacity is insufficient, which easily causes the longitudinal displacement of the vertical gas riser, resulting in the dislocation of the pipe connection position between the riser and the horizontal pipe, and gas leakage. Therefore, a vertical gas pipeline supporting device is invented to avoid the longitudinal displacement of the riser, ensure the stable and safe connection of the gas riser and the pipeline, and reduce the risk of gas leakage.

Specific implementation manners

[0028] The following will further describe the present utility model in detail with reference to the drawings and embodiments. Obviously, the described embodiments are only a part of the embodiments of the utility model, rather than all the embodiments. Without conflict, the embodiments in the present application and the features in the embodiments can be combined with each other. All other embodiments obtained by those of ordinary skill in the art based on the embodiments of the utility model without creative efforts belong to the protection scope of the utility model.

[0029] See Figures 1 to 4 .

[0030] The present utility model discloses a vertical gas pipeline supporting device, which is arranged between two upper and lower gas pipelines. The supporting device includes:

[0031] Cone tube 1, including tube body 11 and conical block 12 fixed in the middle of the outer side of tube body 11. Conical block 12 is coaxial with tube body 11. Both ends of tube body 11 are respectively provided with connection heads for connecting with gas pipelines. The connection head corresponding to the larger diameter end of conical block 12 is connected with the upper gas pipeline;

[0032] Supporting block 2, which is internally provided with a tapered hole that matches the shape of conical block 12. Conical block 12 is embedded in the tapered hole. Both ends of cone tube 1 pass through the tapered hole. The supporting block 2 is used to cooperate with conical block 12 to prevent cone tube 1 from moving downward relative to supporting block 2.

[0033] In specific implementation, the conical pipe 1 is connected between the upper and lower gas pipelines with the larger-diameter end of the conical block 12 facing upward. The supporting block 2 is sleeved outside the conical pipe 1, and then the supporting block 2 can be fixed to the wall through a pipe clamp or other means (such as opening perforations for bolts on the supporting block 2). The gravity of the gas pipeline is transmitted to the supporting block 2 through the conical pipe 1 and then conducted to the wall. The supporting effect is good, which can effectively prevent the longitudinal displacement of the gas pipeline, ensure the stability and safety of the connection between the gas pipeline and the horizontal pipe, and reduce the risk of air leakage.

[0034] Among them, the setting of the conical block 12 makes the supporting force received by the conical pipe 1 more uniform, the stress area larger, and stress concentration does not occur. The gas pipeline will not be deflected or deformed due to uneven stress.

[0035] Preferably, the connector can be connected to the upper and lower gas pipelines by welding, or can be connected to the upper and lower gas pipelines by threaded connection.

[0036] In an embodiment, the conical block 12 and the pipe body 11 are integrally formed. With this design, compared with the later fixed form, integral forming can ensure the coaxiality of the conical block 12 and the pipe body 11, ensure the uniformity and consistency of the connection between the conical block 12 and the pipe body 11, and further ensure the uniformity and consistency of the force conducted to the pipe body 11, and the force on the pipe body 11 is more uniform.

[0037] In an embodiment, an annular tightening groove 21 is opened on the outer side of the supporting block 2, and the tightening groove 21 is used to provide a tightening position for the pipe clamp. In specific implementation, the staff sleeved the pipe clamp outside the tightening groove 21. The setting of the tightening groove 21 enables the supporting block 2 to be more firmly fixed to the wall by the pipe clamp.

[0038] In an embodiment, a limiting member 3 is provided at the end of the supporting block 2 corresponding to the larger-diameter end of the conical block 12, and the limiting member 3 can prevent the conical pipe 1 from separating from the supporting block 2.

[0039] In specific implementation, since this device needs to first pass the conical pipe 1 through the supporting block 2 and then connect the conical pipe 1 to the gas pipeline during use, if there is no setting of the limiting member 3, someone needs to specifically hold the supporting block 2 to prevent the supporting block 2 from falling downward. The setting of the limiting member 3 can well solve this problem and avoid the supporting block 2 from falling downward when the conical pipe 1 is connected to the gas pipeline.

[0040] It should be noted that the limiting component 3 is mainly used to prevent the supporting block 2 from falling downward when the device is installed. After the installation is completed, the limiting component 3 can be disengaged from the limiting of the conical tube 1, allowing the conical tube 1 to have a certain degree of freedom to move upward to match the thermal expansion and contraction effect of the conical tube 1. Of course, if there is a certain gap between the limiting component 3 and the conical tube 1 for the thermal expansion and contraction of the conical tube 1 after the installation of the supporting block 2 is completed, it is also possible not to disengage the limiting component 3 from the limiting of the conical tube 1.

[0041] In one embodiment, the limiting component 3 includes a plurality of blocks 31 fixedly arranged on the supporting block 2. A limiting rod 32 is slidably penetrated through each block 31. One end of the limiting rod 32 can extend towards the end of the conical block 12 and abut against the end face of the larger-diameter end of the conical block 12. One end of the limiting rod 32 can also move in a direction away from the conical block 12 to disengage from the abutment with the conical block 12.

[0042] It should be noted that there are many ways to fix the block 31 on the supporting block 2, such as welding, bolt connection, integral molding, etc.

[0043] In one embodiment, the gas pipeline is a threaded connection type gas pipeline, and the connector is a screw joint, which is screwed to the upper and lower threaded connection type gas pipelines through the screw joint.

[0044] In one embodiment, a ball 33 is arranged at the position where the limiting rod 32 abuts against the end face of the conical block 12. The limiting rod 32 is in rolling fit with the end face of the conical block 12 through the ball 33. With this design, when the conical tube 1 is connected to the gas pipeline, the supporting block 2 can not rotate synchronously with the conical tube 1, which is convenient for the operation of the staff and also convenient for the subsequent fixing operation of the supporting block 2.

[0045] In one embodiment, the limiting rod 32 is in a long strip shape, and a card slot 34 is formed on one side. A clamping plate 35 is penetrated through the side of the block 31 opposite to the card slot 34. The clamping plate 35 is used to be clamped with the card slot 34 to limit the limiting rod 32;

[0046] A first elastic member 36 is arranged between the clamping plate 35 and the block 31. The first elastic member 36 is used to push the clamping plate 35 to move towards the card slot 34 to limit the limiting rod 32. With this design, it can be avoided that the limiting rod 32 easily disengages from the abutment with the conical block 12.

[0047] Preferably, a push plate for pushing the limiting rod 32 to move is arranged at the end of the limiting rod 32 away from the ball 33; one end of the clamping plate 35 penetrates through the block 31 and is provided with a lifting handle 351 for lifting the clamping plate 35 to move the clamping plate 35 in a direction away from the card slot 34.

[0048] In one embodiment, a second elastic member 37 is provided between the limiting rod 32 and the block 31, and the second elastic member 37 is used to push the limiting rod 32 to move away from the cone tube 1. With this design, when the clamping plate 35 releases the constraint with the clamping groove 34, the second elastic member 37 helps to quickly move away from the cone tube 1 without manually pulling the limiting rod 32.

[0049] It can be understood that when the second elastic member 37 is in a compressed state, it cannot, conversely, release the limit between the clamping plate 35 and the clamping groove 34.

[0050] As for how the second elastic member 37 is arranged between the limiting rod 32 and the block 31, this belongs to the common knowledge of those skilled in the art. For example, a space for installing the second elastic member 37 can be opened in the block 31, and one side of the limiting rod 32 extends into this space, so that when the limiting rod 32 moves towards the cone tube 1, the second elastic member 37 can be compressed.

[0051] Preferably, the first elastic member 36 and the second elastic member 37 are both springs.

[0052] The above are only the preferred embodiments of the present utility model and are not intended to limit the present utility model. Any modifications, equivalent replacements, improvements, etc. made within the spirit and principle of the present utility model shall be included within the protection scope of the present utility model.

[0053] It should be noted that if the embodiments of the utility model involve directional indications (such as up and down), the directional indications are only used to explain the relative positional relationship and movement conditions between components in a specific posture (as shown in the drawings). If the specific posture changes, the directional indications will also change accordingly.

[0054] In addition, if the descriptions such as "first" and "second" are involved in the embodiments of the utility model, the descriptions of "first", "second", etc. are only for descriptive purposes and cannot be understood as indicating or implying their relative importance or implicitly indicating the quantity of the indicated technical features. Thus, the features defined with "first" and "second" may explicitly or implicitly include at least one such feature. In addition, "a plurality" means more than two. In addition, the technical solutions between various embodiments can be combined with each other, but it must be based on the fact that those skilled in the art can implement it. When the combination of technical solutions is contradictory or cannot be implemented, it should be considered that such a combination of technical solutions does not exist and is not within the protection scope required by the utility model.
