Description

Technical Field

[0001] The utility model relates to the technical field of gas pipeline installation, in particular to an electric fusion sleeve installation device. Background Art

[0002] There are many common gas PE pipes and electric fusion sleeve models on the market. The matching degree between the two is not exactly the same, resulting in size mismatches in some pipes when installing electric fusion sleeves, causing the sleeve to be very tight when installed on the pipe. The current practice is to use a rubber hammer to knock on the side of the electric fusion sleeve to install the electric fusion sleeve on the pipe.

[0003] Problems with the current approach:

[0004] 1. If the rubber hammer hits the fusion sleeve with too small a surface, the side of the fusion sleeve will be deformed, damaging the sleeve and affecting its quality.

[0005] 2. Only one point can be struck at a time, and the force cannot be evenly distributed around the sleeve, which will cause the sleeve to tilt in the diagonal direction of the strike, causing the contact surface between the sleeve and the pipe to tilt, affecting the welding quality;

[0006] 3. Improper striking (the contact surface between the hammer and the fusion sleeve is only 1 cm), which may cause damage to the pipeline and operators when it slips;

[0007] 4. When the installation resistance of the electric fusion sleeve is too large, the electric fuse with exposed wires inside the sleeve may be damaged or squeezed together, causing a short circuit or open circuit and damaging the electric fusion sleeve. Utility Model Content

[0029] The following will be combined with the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the embodiments described are only part of the embodiments of the present invention, not all of the embodiments. In the absence of conflict, the embodiments in this application and the features in the embodiments can be combined with each other. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative work are within the scope of protection of the present invention.

[0030] It should be noted that if the embodiments of the present invention involve directional indications (such as up, down, left, right, front, back, etc.), the directional indications are only used to explain the relative position relationship, movement status, etc. between the components in a certain specific posture. If the specific posture changes, the directional indications will also change accordingly.

[0031] Reference Figure 1-Figure 4 As shown, an electric fusion sleeve installation device is installed to connect two pipes, where the two pipes are assumed to be pipe A and pipe B, including:

[0032] Fixed frame 1;

[0033] The collar 2 is mounted on the fixing frame 1 and sleeved on the pipe A;

[0034] The pushing component 3 is clamped on the pipe A and is used to push the movement of the electric fusion sleeve;

[0035] The clamping assembly 5 is provided on one side of the fixing frame 1 and is used to fix the pipe B on the other side;

[0036] The telescopic component 4 is provided between the fixing frame 1 and the clamping component 5 and is used to adjust the distance between the clamping component 5 and the fixing frame 1;

[0037] When installing the electric fusion sleeve, first completely put the electric fusion sleeve on the pipe A. This is a whole end face and can be installed by tapping with a rubber hammer. After installation, put the ring 2 on the pipe A at the rear end of the electric fusion sleeve and move the position of the clamping component 5 through the telescopic component 4 so that the clamping component 5 can clamp and fix the pipe B. Then, push the electric fusion sleeve through the pushing component 3 so that the electric fusion sleeve moves half a body position to the middle of the two pipes.

[0038] In one embodiment, the collar 2 includes a first limiting plate 21 and a second limiting plate 22 in a semicircular shape. One end of the first limiting plate 21 is rotatably connected to the second limiting plate 22 via a fixed rotating shaft 23. A positioning block 24 is provided at the other end of the first limiting plate 21. The second limiting plate 22 is clamped on the positioning block 24. A locking rod 25 is provided on one side of the positioning block 24. The positioning block 24 is fixedly connected to the second limiting plate 22 via the locking rod 25.

[0039] The collar 2 itself can be opened for easy installation and removal. During installation, the two limit plates are placed on the pipe A, and then the positioning block 24 is inserted into the second limit plate 22, and finally fixed by the locking rod 25.

[0040] In one embodiment, the pushing assembly 3 includes multiple groups of hydraulic cylinders 31. These hydraulic cylinders 31 are distributed in a circular array on the inner side of the collar 2. The output ends of the hydraulic cylinders 31 are connected to push plates 32. The push plates 32 are tightly attached to the electrofusion sleeve. The bottoms of the hydraulic cylinders 31 are tightly attached to the pipe A via rubber pads 33.

[0041] After the hydraulic cylinder 31 is tightly attached to the pipe A, the push plate 32 can be pushed by the hydraulic cylinder 31. The push plate 32 is also distributed in a circular array on the electrofusion sleeve, so that the force on the electrofusion sleeve is more uniform. Here, the synchronous movement of all hydraulic cylinders 31 can be achieved by using synchronization valves, electro-hydraulic servo valves to control synchronization, series hydraulic synchronization, flow control synchronization and other methods.

[0042] In one embodiment, a mounting bracket 34 is provided on the hydraulic cylinder 31, a rotating block 35 is rotatably provided on the mounting bracket 34, a first threaded rod 36 is provided on the rotating block 35, and the first threaded rod 36 is threadedly connected to the collar 2;

[0043] Since the sizes of pipes vary, during installation, a lifting device may be provided to enable the hydraulic cylinder 31 to be in close contact with the pipe A. That is, by rotating the first threaded rod 36, the hydraulic cylinder 31 may be driven downward, thereby allowing the hydraulic cylinder 31 to be in close contact with the pipe A and also clamping and fixing the pipe A.

[0044] In one embodiment, the telescopic assembly 4 includes a fixed sleeve 41 fixed to the fixed frame 1, a telescopic rod 42 is slidably arranged in the fixed sleeve 41, and the clamping assembly 5 is fixed to one end of the telescopic rod 42. A limit groove is defined in the side wall of the fixed sleeve 41, and a groove is defined at the end of the telescopic rod 42 away from the clamping assembly 5. A limit spring 44 is disposed in the groove, and a limit rod 43 is disposed at one end of the limit spring 44.

[0045] After installing the pushing component 3, in order to align the two pipes, the telescopic component 4 can be used to push the clamping component 5, so that the clamping component 5 is moved to the pipe B, and then the pipe B is fixed and clamped by the clamping component 5, which can be regarded as a support for the pipe B.

[0046] In one embodiment, the clamping assembly 5 includes a base plate 51 connected to the telescopic rod 42, a bidirectional threaded rod 52 is rotatably provided in the base plate 51, and vertical plates 53 are provided at both ends of the base plate 51. The two vertical plates 53 are respectively sleeved on the two ends of the bidirectional threaded rod 52. A movable plate 54 is fixedly provided on the top of the vertical plate 53, and a clamping plate 55 is provided on the inner side of the movable plate 54. A second threaded rod 56 is rotatably provided on one side of the clamping plate 55, and the second threaded rod 56 is threadedly connected to the movable plate 54.

[0047] First, rotate the two-way threaded rod 52 at the bottom to make the two vertical plates 53 approach each other, and then rotate the second threaded rod 56 to move the two clamping plates 55 inward and clamp them on pipe B to fix and support pipe B, keep pipe B aligned with pipe A, and facilitate the movement of the electric fusion sleeve.

[0048] It will be apparent to those skilled in the art that the present invention is not limited to the details of the exemplary embodiments described above, and that the present invention can be implemented in other specific forms without departing from the spirit or essential features of the present invention. Therefore, the embodiments should be considered in all respects as illustrative and non-restrictive, and the scope of the present invention is defined by the appended claims rather than the foregoing description, and it is intended that all variations that come within the meaning and range of equivalents of the claims be embraced within the present invention.
