Description

Technical Field

[0001] The utility model relates to the technical field of pipeline installation protection, and particularly relates to a safety protection cover for chemical pipelines. Background Art

[0002] During the installation of chemical pipelines, in order to reduce the damage caused by the collision of chemical pipelines with surrounding equipment or terrain during installation, a protective cover is often sleeved outside the chemical pipelines to protect the chemical pipelines. Except for some seamless pipelines, most chemical pipeline installations require connecting multiple pipe bodies end to end to form a longer chemical pipeline.

[0003] When connecting multiple installations, the operator needs to align and connect multiple pipe bodies. Therefore, the position of the pipe bodies needs to be continuously adjusted. After alignment, the connection between two adjacent pipe bodies is welded to form a complete chemical pipeline from multiple pipe bodies. However, after the protective cover is sleeved on the pipe body, the combined volume of the pipe body and the protective cover is relatively large, and it takes more time to align the pipe bodies, which will increase the construction time of the operator. Summary of the Utility Model

[0004] In view of this, the purpose of the utility model is to provide a safety protection cover for chemical pipelines to solve the problem that after the protective cover is sleeved on the pipe body, the combined volume of the pipe body and the protective cover is relatively large, which is not convenient for the operator to align two adjacent pipe bodies and will increase the construction time of the operator.

[0033] Please refer to Figures 1-4 , the present utility model provides a technical solution: a safety protective cover for chemical pipelines, including two protective plates 1 in a semi-circular ring structure. The two ends of the two protective plates 1 are connected to form a ring structure. A base 2 is arranged between the lower parts of the two protective plates 1. The two sides of the base 2 are respectively hinged to the lower parts of the two protective plates 1. Two protruding parts 3 extending in a direction away from the protective plates 1 are respectively arranged on the upper parts of the two protective plates 1. One side of the two protruding parts 3 abuts against each other, and a chute 301 is arranged on the other side. The chute 301 penetrates through the end of the protruding part 3 along the length direction of the protruding part 3;

[0034] It also includes a positioning member. The two ends of the positioning member can be respectively inserted into the two chutes 301, and the positioning member can slide along the length direction of the chute 301.

[0035] Among them, the two protective plates 1, as movable parts, can present the following states under the cooperation of the positioning member and the chute 301:

[0036] State 1: When the two ends of the positioning member are not inserted into the chute 301, the two protruding parts 3 and the two protective plates 1 are not fixed by the positioning member and can respectively rotate around the hinge joint with the base 2 as the axis.

[0037] State 2: The two protective plates 1 and the two protruding parts 3 abut against each other respectively, and the two ends of the positioning member are inserted into the chute 301. In this state, the two protective plates 1 form a cover body that can be sleeved outside the pipe body through the base 2, the protruding parts 3 and the positioning member.

[0038] During specific use, first, adjust the states of the two protective plates 1 to State 1, causing the two protective plates 1 to unfold by rotating away from each other. The operator places the pipe body on the top surface of the base 2, and then adjusts the two protective plates 1 to State 2 to form a cover body sleeved on the outer wall of the pipe body.

[0039] The operator brings the opposite ends of the two cover bodies closer and judges whether they are aligned by whether the protruding parts 3 and the sliding grooves 301 on the two cover bodies can form a straight line. When the operator visually observes that the protruding parts 3 on the two cover bodies form a straight line, slide the positioning member on any one of the cover bodies in the direction towards the other cover body. If one end of the positioning member can pass through the sliding groove 301 on the other cover body, it means that the two sliding grooves 301 are aligned, that is, the two cover bodies and the pipe body are aligned.

[0040] Then, an additional positioning member can be added on the basis of the two positioning members, so that the positioning member is located between the two cover bodies, and the two ends of the positioning member are respectively located in the sliding grooves 301 on the two cover bodies, thereby fixing the aligned state of the two cover bodies and the pipe body to facilitate the operator to weld the connecting parts of the two pipe bodies.

[0041] When using the safety protective cover of the present utility model to protect the pipe body, while the pipe body can be protected by sleeving the cover body on the outer wall of the pipe body, the protruding parts 3 and the sliding grooves 301 can better guide the alignment of two adjacent pipe bodies, and the alignment state of the two pipe bodies is fixed by the positioning member.

[0042] In this embodiment: the positioning member includes a transverse section 4, two vertical sections 401 located on both sides of the transverse section 4, and two sliders 402. The transverse section 4 is located on the top surfaces of the two protruding parts 3. The vertical sections 401 are perpendicularly connected to the side surfaces of the transverse section 4. The two sliders 402 are respectively located on the opposite sides of the two vertical sections 401. The two sliders 402 extend in opposite directions, and the two sliders 402 can be slidably matched with the sliding grooves 301.

[0043] Among them, the transverse section 4, the two vertical sections 401, and the two sliders 402 form an integral positioning structure;

[0044] During the process of adjusting the states of the two protective plates 1 from State 1 to State 2, first, the operator closes the two protective plates 1 to make the two protruding parts abut against each other. Then, the operator inserts the positioning structure through one end of the two protruding parts into the sliding groove 301, so that the two sliders 402 are respectively located in the two sliding grooves 301. The two protective plates 1 are limited by the cooperation of the two vertical sections 401 and the transverse section 4, so that the two protective plates 1 cannot rotate, thereby keeping the two protective plates 1 in the state of State 2.

[0045] In this embodiment: a plug-in member is provided on the transverse section 4, the plug-in member is slidably engaged with the transverse section 4, and the plug-in member can slide along the height direction of the transverse section 4;

[0046] On the top surfaces of both of the protruding portions 3, a plurality of sets of insertion holes 302 for inserting the plug-in member are provided.

[0047] Among them, in the second state, the two baffles are squeezed by the inner tube body and tend to move away from each other, and then the protruding portion squeezes the two vertical sections 401, so that the transverse section 4 is stressed by the two protective plates 1.

[0048] During specific use, the plug-in member vertically penetrates the transverse section 4 and is inserted into the top surface of the protruding portion 3 to fix the fixing member and the protruding portion 3, thereby enhancing the fixing effect on the two baffles. At the same time, the plug-in member is inserted into the protruding portion 3 to share part of the stress borne by the transverse section 4.

[0049] In this embodiment: the plug-in member includes a fixing plate 5 located on the top surface of the transverse section 4 and two groups of insertion rods 501. The top surfaces of the two insertion rods 501 are fixedly connected to the bottom surface of the fixing plate 5, and through holes for the insertion rods 501 to pass through are provided on the top surface of the transverse section 4.

[0050] Among them, at both ends of the top surface of each protruding portion 3, a set of insertion holes 302 is provided. A set of insertion holes 302 includes at least two insertion holes arranged along the length direction of the protruding portion 3; the two groups of insertion rods 501 are arranged along the width direction of the fixing plate 5, and each group of insertion rods 501 includes at least two rod bodies respectively installed at both ends of the fixing plate 5;

[0051] The distance between the two insertion holes is equal to the distance between the two insertion rods 501.

[0052] Thus, the operator can insert the plug-in member into the four insertion holes 302 at one end of the two protruding portions 3 to fix the two protruding portions 3 and the two protective plates 1;

[0053] At the same time, the operator can move the two covers to make the ends of the two covers close together, and then insert the plug-in member into the four relatively close insertion holes 302 on the two covers to fix the two covers.

[0054] In this embodiment: an elastic connecting member 6 is provided between the fixing plate 5 and the transverse section 4, and both ends of the elastic connecting member 6 are respectively connected to the fixing plate 5 and the transverse section 4.

[0055] Among them, the elastic connecting member 6 is a tension spring, and both ends are respectively connected to the fixing plate 5 and the transverse section 4. In the natural state, the fixing plate 5 is always kept in a tendency to lean towards the transverse section 4, so that the insertion rod 501 is inserted into the insertion hole 302 and is not likely to fall off naturally.

[0056] In this embodiment: Connecting blocks 7 and connecting grooves 701 are respectively arranged at both ends of the base 2. Both the connecting blocks 7 and the connecting grooves 701 extend along the length direction of the base 2, and the length of the connecting blocks 7 is greater than that of the connecting grooves 701.

[0057] During specific use, when aligning the two covers, insert the connecting block 7 of one cover into the connecting groove 701 of the other cover to make the lower ends of the two covers aligned. At the same time, cooperate with the protruding parts 3, sliding grooves 301 and positioning parts on the two covers to align the upper ends of the two covers, so as to ensure the alignment between the two pipe bodies.

[0058] Among them, since the length of the connecting block 7 is greater than that of the connecting groove 701, after the connecting block 7 is inserted into the connecting groove 701, there is a certain interval space between the two covers, and the abutting ends of the two pipe bodies are located in the interval space, which is convenient for the operator to weld the abutting ends of the two pipe bodies.

[0059] In this embodiment: A plurality of moving wheels 8 are arranged on the top surface of the base 2, and the plurality of moving wheels 8 are evenly distributed along the length direction of the base 2.

[0060] When the two baffles are in the first state, the operator places the pipe body on the base 2. At this time, the bottom surface of the pipe body abuts against the top surfaces of the moving wheels 8. The operator can push one end of the pipe body to make the pipe body slide on the base 2 until the middle part of the pipe body is located on the base 2 to improve the balance state of the pipe body on the base 2;

[0061] After the pipe body is welded, directly move the cover to roll on the bottom surface of the pipe body through the moving wheels 8, and the cover can be gradually moved away from the pipe body, and then the cover is recycled.

[0062] In this embodiment: On the inner sides of the two protection plates 1, clamping members whose two clamping surfaces can move along the diameter direction of the pipe body are respectively arranged. The clamping members are located between the pipe body and the protection plates 1, and the opposite two surfaces of the clamping members abut against the pipe body and the protection plates 1 respectively.

[0063] During specific use, when the pipe body is located inside the cover, by adjusting the clamping surfaces of the clamping members to abut against the pipe body, the pipe body is not easy to shake inside the cover, thereby improving the stability of the cover.

[0064] In this embodiment: The clamping member includes a mounting plate. An air bag 901 is arranged on the surface of the mounting plate away from the protection plate 1. A valve 902 is arranged on the surface of the mounting plate away from the protection plate 1. One end of the valve 902 penetrates through the mounting plate and communicates with the inside of the air bag 901.

[0065] Among them, the valve 902 is a valve structure equipped with a handwheel, and the operator can open or close the valve 902 by rotating the handwheel;

[0066] During specific use, an operator can connect an external air pump or an inflatable piston to the valve 902, and input gas into the airbag 901 through the valve 902 to cause the airbag 901 to expand. When one side of the airbag 901 close to the pipe body abuts against the pipe body, the valve 902 is closed, and the pipe body is clamped by the frictional force between the airbag 901 and the pipe body. When the cover body needs to be recycled, the valve 902 is opened again to release the gas in the airbag 901. After the pipe body loses the clamping of the airbag 901, it is convenient for the cover body and the pipe body to be separated.

[0067] In this embodiment: an opening 101 is formed on the outer side surface of the protection plate 1, and the opening 101 penetrates through two opposite side surfaces in the middle of the protection plate 1;

[0068] The mounting plate includes two folding plates 9, and the two folding plates 9 are mounted at both ends of the side of the airbag 901 away from the pipeline.

[0069] Among them, the two folding plates 9 can present the following states according to whether the airbag 901 expands:

[0070] State 1: In the expanded state of the airbag 901, one side of the two folding plates 9 is supported by the airbag 901, so that the two folding plates 9 are both parallel to the airbag 901;

[0071] State 2: When the airbag 901 contracts, the two folding plates 9 lose the support of the airbag 901. Since the two folding plates 9 are only connected by the airbag 901, and the airbag 901 is made of a flexible material, the two folding plates 9 can move relative to each other until they gradually overlap.

[0072] During specific use, when installing the pipe body, the pipe body is located inside the cover body. The operator puts the folding plate 9 in the state 2 into the cover body through the opening 101, and makes the airbag 901 face the pipe body. Then the operator manually unfolds the two folding plates 9, and inflates the airbag 901 through an air pump or an inflatable piston to cause the airbag 901 to expand. As the airbag 901 expands, one side of the airbag 901 abuts against the pipe body, and the other side presses against the folding plate 9, so that the folding plate 9 abuts against the inner wall of the cover body, so as to ensure that the clamping member is stably located inside the cover body to clamp the pipe body;

[0073] When the cover body needs to be recycled, the operator releases the gas in the airbag 901 by opening the air valve. As the gas is released, the airbag 901 gradually contracts. At this time, the operator manually makes the two folding plates 9 gradually overlap. When the width is less than the opening 101, the clamping member is taken out.

[0074] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of the present utility model rather than to limit them. Although the present utility model has been described in detail with reference to the preferred embodiments, those of ordinary skill in the art should understand that the technical solutions of the present utility model can be modified or equivalently replaced without departing from the purpose and scope of the technical solutions of the present utility model, and they should all be covered within the scope of the claims of the present utility model.
