Description

Technical Field

[0001] This utility model relates to the field of pipeline thermal fusion connection technology, and in particular to an auxiliary fixing device for pipeline thermal fusion connection. Background Technology

[0002] Pipeline fusion is a technique that involves heating the pipe ends to a molten state and then applying pressure to connect them. It is mainly used in the processing of plastic pipes such as polyethylene (PE) and polypropylene (PP) and has advantages such as strong connection, good sealing, and quick construction.

[0003] During plumbing and electrical work, when connecting two water pipes, the plumber must simultaneously pick up both pipes and press the mating surfaces of the two plastic pipes tightly against a heating tool. The flat ends of the pipes are heated until they melt. After removing the heating tool, the two molten ends are pressed together and held under pressure until the joint cools, thus connecting the two pipe sections into a single unit. Because the pipe joint requires pressing the two molten ends together under pressure after fusion, the operator must apply continuous force during this process. If the force is not applied continuously, the two pipe ends will not fit completely together, creating a gap that becomes a leakage channel. Utility Model Content

[0004] To overcome the problem that operators need to apply continuous force when pressing the two molten ends together, otherwise the two pipe ends will not fit completely together, forming a gap that becomes a leakage channel.

[0005] The technical solution of this utility model is: an auxiliary fixing device for pipe hot-melt connection, including a working frame, with fixing mechanisms provided on both sides of the top of the working frame, and a pushing mechanism provided in the inner cavity of the working frame;

[0006] The fixing mechanism includes a support rod, a lower clamp is provided at the top of the support rod, the lower clamp is movably connected to an upper clamp via a hinge, and the lower clamp and the upper clamp are fixed together by bolts.

[0007] The pushing mechanism includes a motor, the output shaft of which is driven by a reducer, the output shaft of which is driven by a threaded rod, the surface of which is threaded with a threaded sleeve, and the top of the threaded sleeve is fixedly connected to the support rod on the right side.

[0008] Preferably, the lower clamp and the upper clamp are connected by a hinge. After opening the upper clamp, the pipe is placed on the lower clamp, and then the upper clamp is reset. The lower clamp and the upper clamp are fixed with bolts to secure the pipe. The centers of the lower clamp and the upper clamp on both sides are horizontal. Both pipes are fixed in this way. Then, the heat fusion device is placed between the two pipes, the motor is started, and the output shaft of the motor drives the output shaft of the reducer to rotate. In turn, the reducer drives the threaded rod to rotate, and the threaded sleeve drives the right-side fixing mechanism along with the fixed pipe to move to the left to receive the heat fusion. After the heat fusion is completed, the output shaft of the motor rotates in the opposite direction. After the heat fusion device is removed, the motor is started again, so that the fixing mechanism along with the fixed pipe moves to the left again until the fused ends of the two pipes are pressed together and held under pressure until the joint cools down.

[0009] Preferably, the support rod on the left is fixedly connected to the top of the work frame by bolts.

[0010] Preferably, a limiting sliding hole is provided on the right side of the top of the work frame, and the top of the right support rod extends to the outer surface of the limiting sliding hole and is slidably connected thereto.

[0011] Preferably, both the motor and the reducer are fixedly connected to the inner cavity of the work frame, and one end of the threaded rod is fixedly connected to the inner cavity of the work frame through a bearing seat.

[0012] Preferably, the top of the support rod is provided with a threaded hole, and the bottom of the lower clamp is fixedly connected with a screw rod, which is threadedly connected to the threaded hole.

[0013] Preferably, a limiting slide is provided at the bottom of the inner cavity of the work frame, and a limiting pulley is connected to the bottom of the threaded sleeve, and the limiting pulley slides with the inner cavity of the limiting slide.

[0014] Preferably, the device also includes a pressing mechanism, which includes a bracket fixedly connected to the top of the work frame, a side plate fixedly connected to one end of the bracket, an electric push rod fixedly connected to one side of the side plate, a sliding plate fixedly connected to the output end of the electric push rod, and a push plate fixedly connected to one side of the sliding plate by bolts. The sliding plate is sleeved on the surface of the bracket and slidably connected to it.

[0015] The beneficial effects of this utility model are as follows: the fixing mechanism can fix the pipe, and the pushing mechanism can drive the right fixing mechanism to move to the left during the hot melting operation. After the hot melting is completed, the pushing mechanism drives the right fixing mechanism to move to the right and take out the hot melting equipment. At this time, the pushing mechanism drives the right fixing mechanism and the pipe to move to the left to connect with the left pipe. The setting of the pushing mechanism can make the molten end faces of the two pipes close together and keep them under pressure until the joint cools down. Attached Figure Description

Detailed Implementation

[0023] The present invention will be further described below with reference to the accompanying drawings and embodiments.

[0024] Example 1

[0025] Please see Figure 1 , Figure 2 and Figure 3 This utility model provides an embodiment: an auxiliary fixing device for pipe hot-melt connection, including a working frame 1, fixing mechanisms 2 are provided on both sides of the top of the working frame 1, and a pushing mechanism 3 is provided in the inner cavity of the working frame 1;

[0026] The fixing mechanism 2 includes a support rod 201, a lower clamp 202 is provided on the top of the support rod 201, the lower clamp 202 is movably connected to the upper clamp 203 by a hinge, and the lower clamp 202 and the upper clamp 203 are fixed by bolts;

[0027] The driving mechanism 3 includes a motor 301, the output shaft of the motor 301 is driven to a reducer 302, the output shaft of the reducer 302 is driven to a threaded rod 304, the surface of the threaded rod 304 is threaded to a threaded sleeve 303, and the top of the threaded sleeve 303 is fixedly connected to the right support rod 201.

[0028] During operation, the lower clamp 202 and the upper clamp 203 are connected by a hinge. After opening the upper clamp 203, the pipe is placed on the lower clamp 202. Then, the upper clamp 203 is reset, and the lower clamp 202 and the upper clamp 203 are fixed with bolts to secure the pipe. The centers of the lower clamps 202 and the upper clamps 203 on both sides are horizontal. Both pipes are fixed in this way. Then, the heat fusion equipment is placed between the two pipes, and the motor 301 is started. The output shaft of the motor 301 drives the output shaft of the reducer 302 to rotate. The reducer 302 drives the threaded rod 304 to rotate, and the threaded sleeve 303 in turn drives the right-side fixing mechanism 2, along with the fixed pipe, to move to the left to receive the heat melt. After the heat melt is completed, the output shaft of the motor 301 rotates in the opposite direction. After the heat melt equipment is removed, the motor 301 is started, causing the fixing mechanism 2, along with the fixed pipe, to move to the left again. Pressure is slowly applied until the molten ends of the two pipes are pressed together. When the ends are pressed together, the motor 301 can be stopped to keep the right-side fixing mechanism 2 in position and maintain it under pressure until the joint cools down.

[0029] Example 2

[0030] Please see Figure 1 and Figure 2 The difference from Embodiment 1 is that the left support rod 201 is fixedly connected to the top of the work frame 1 by bolts.

[0031] A limiting slide hole 5 is provided on the right side of the top of the work frame 1, and the top of the right support rod 201 extends to the outer surface of the limiting slide hole 5 and is slidably connected to it.

[0032] Both the motor 301 and the reducer 302 are fixedly connected to the inner cavity of the work frame 1, and one end of the threaded rod 304 is fixedly connected to the inner cavity of the work frame 1 through a bearing seat.

[0033] The left support rod 201 is fixed to the top of the work frame 1 by bolts, which facilitates the disassembly of the support rod 201. By setting the limiting sliding hole 5, the support rod 201 can be limited by the limiting sliding hole 5 during the movement, ensuring that the movement trajectory of the support rod 201 can be kept without deviation. The motor 301 and the reducer 302 are set in the inner cavity of the work frame 1 for driving the threaded rod 304. The bearing seat is used to fix and support the threaded rod 304.

[0034] Example 3

[0035] Please see Figure 3 and Figure 4 The difference from Embodiment 1 is that the top of the support rod 201 is provided with a threaded hole 204, and the bottom of the lower clamp 202 is fixedly connected with a screw 205, which is threadedly connected to the threaded hole 204.

[0036] A limiting slide 6 is provided at the bottom of the inner cavity of the work frame 1, and a limiting pulley is connected to the bottom of the threaded sleeve 303, and the limiting pulley slides in the inner cavity of the limiting slide 6.

[0037] The threaded fixing method of the threaded hole 204 and the screw 205 allows for easy disassembly and assembly of the lower clamp 202 and the upper clamp 203, facilitating the replacement of lower clamps 202 and upper clamps 203 of different sizes for fixing pipes. The setting of the limiting slide 6 is used to limit the limiting pulley at the bottom of the threaded sleeve 303, ensuring that the left and right movement trajectory of the threaded sleeve 303 does not deviate.

[0038] Example 4

[0039] Please see Figure 5 The difference from Embodiment 1 is that it also includes a pushing mechanism 4. The pushing mechanism 4 includes a bracket 401 fixedly connected to the top of the work frame 1, a side plate 402 fixedly connected to one end of the bracket 401, an electric push rod 403 fixedly connected to one side of the side plate 402, a sliding plate 404 fixedly connected to the output end of the electric push rod 403, and a push plate 405 fixedly connected to one side of the sliding plate 404 by bolts. The sliding plate 404 is sleeved on the surface of the bracket 401 and slidably connected to it.

[0040] The push mechanism 4 can assist in fixing the pipe during fusion welding without using the push mechanism 3. After the pipe is placed on the lower clamp 202, the upper clamp 203 is not closed. The lower clamp 202 supports the pipe. The output shaft of the electric push rod 403 extends, driving the sliding plate 404 and the push plate 405 to move. The push plate 405 can connect with the pipe on the lower clamp 202. The width of the push plate 405 here needs to be greater than the pipe diameter. Therefore, it can be replaced by bolt removal and installation. The hot melt equipment is placed between the two pipes. The electric push rods 403 at both ends extend simultaneously to accept the hot melt. After the hot melt is completed, the hot melt equipment is removed. The electric push rod 403 is pushed again. The pressure needs to be applied slowly so that the pipe can maintain continuous pressure and bring the two fused end faces together. When the end faces are close together, the electric push rod 403 can be stopped. The extension length of the electric push rod 403 is maintained. The pressure is maintained until the joint cools down, so that the two pipe sections are connected into a whole.

[0041] The embodiments of the present invention have been described in detail above with reference to the accompanying drawings. However, the present invention is not limited to the above embodiments. Within the scope of knowledge possessed by those skilled in the art, various changes can be made without departing from the spirit of the present invention.
