Description

[0003] Flaring is a common processing technology for such pipes, the purpose of which is to facilitate the connection of other pipes or accessories and ensure the convenience and sealing of installation; flaring is to put the power pipe on the support rod, limit the outside of the power pipe, then use the heating equipment to heat the power pipe, and then move the flaring drill to the flaring position of the power pipe to perform the flaring operation, and then use the water pipe located above the power pipe to spray water to cool the flared part.

[0027] In order to make the above-mentioned objects, features and advantages of the present invention more obvious and easy to understand, the specific embodiments of the present invention are described in detail below in conjunction with the accompanying drawings. In the following description, many specific details are set forth to facilitate a full understanding of the present invention. However, the present invention can be implemented in many other ways different from those described below, and those skilled in the art can make similar improvements without violating the connotation of the present invention. Therefore, the present invention is not limited to the specific embodiments disclosed below.

[0028] See also Figure 1 , Figure 2 and Figure 4 A BWFRP power pipe flaring processing device comprises a fixing seat 1 with a circular through hole in the middle, the fixing seat 1 is fixedly connected to the working ground, a telescopic inner support rod 2 for inner support of the power pipe is arranged on the left side of the fixing seat 1, the fixed end of the telescopic inner support rod 2 is fixedly connected to an external device, and a flaring drill 3 for flaring the power pipe is arranged on the right side of the fixing seat 1, and the rear side of the flaring drill 3 is fixedly connected to a moving push plate 6 through a fixing rod; a fixed ring tube 4 is sleeved on the outer side of the telescopic inner support rod 2, and the fixed ring tube 4 is fixed by a support frame Connected to the working ground, a plurality of water leakage holes are opened on the lower side of the fixed ring tube 4. Since the water leakage holes are small, they are not shown in the attached drawings. When the water leakage holes are used for subsequent cooling operations, the sprayed cold water can be discharged from the fixed ring tube 4 in time, and the excess water can also flow out from the left and right sides of the fixed ring tube 4. A spray assembly 41 is arranged on the inner side of the fixed ring tube 4, and a resisting assembly 42 is symmetrically arranged on the outer wall of the fixed ring tube 4; a pressure maintaining assembly 5 is symmetrically arranged on the outer side of the expanding drill bit 3 and corresponds to the position of the spray assembly 41, and is used to maintain the pressure of the expanded power pipe.

[0029] During operation, the power pipe is sleeved on the telescopic inner support rod 2, and the movable push plate 6 is pushed to drive the flaring drill bit 3 to move. The flaring drill bit 3 flares the power pipe sleeved on the telescopic inner support rod 2. After the flaring is completed, the resisting component 42 is opened to start the cooling work, and the flaring drill bit 3 and the pressure maintaining component 5 are correspondingly withdrawn, and the resisting component 42 is allowed to continue the cooling operation.

[0030] See also Figure 1 and Figure 2 A fixed limit rod 11 is fixedly connected to the right side of the fixed seat 1, and the fixed limit rod 11 penetrates and slides on the movable push plate 6. A hydraulic electric push rod is connected to the right side of the movable push plate 6, which is not shown in the figure.

[0031] When it is necessary to push the expanding drill bit 3 into the electric power pipe on the telescopic inner support rod 2, start the hydraulic electric push rod on the rear side of the movable push plate 6, and the hydraulic electric push rod pushes the movable push plate 6 to move along the fixed limit rod 11 in the direction close to the fixed seat 1 until it drives the expanding drill bit 3 to be pushed into the electric power pipe, pushes the telescopic inner support rod 2 to the left and performs the expanding operation on the electric power pipe.

[0032] See also Figure 1 and Figure 2 A trumpet-shaped inlet is provided on the right side of the fixed ring tube 4, and an inclined groove is provided on the left side of the corresponding semi-arc pressure-maintaining plate 54. The diameter of the inner wall on the left side of the fixed ring tube 4 is equal to the diameter of the outer wall of the circle formed by the two semi-arc pressure-maintaining plates 54.

[0033] When the semi-arc pressure-maintaining plate 54 enters the inner side of the fixed ring tube 4, the left side of the semi-arc pressure-maintaining plate 54 contacts the inner wall of the fixed ring tube 4, and the upper and lower semi-arc pressure-maintaining plates 54 will approach each other, and the first spring 57 will be gradually compressed until the upper and lower semi-arc pressure-maintaining plates 54 form a complete circle, and the inner wall of the semi-arc pressure-maintaining plate 54 will be completely fitted against the outer wall of the expanded power tube to perform the pressure-maintaining operation.

[0034] See also Figure 2 , Figure 4 and Figure 5 The spray assembly 41 includes two inner ring wall grooves 411 opened on the inner wall of the fixed ring tube 4, a sliding groove 412 is opened between the two inner ring wall grooves 411, and an annular water pipe 413 is rotatably connected in the inner ring wall grooves 411. A docking water pipe 414 is fixedly connected between the two annular water pipes 413, and the docking water pipe 414 slides in the sliding groove 412. A plurality of spray heads are evenly arranged on the inner ring wall of the annular water pipe 413 in the circumferential direction, and a receiving groove connected to one of the inner ring wall grooves 411 is opened on the rear side of the outer side wall of the telescopic inner support rod 2, and a flexible soft water pipe 415 is fixedly connected to the rear side of the corresponding annular water pipe 413. The flexible soft water pipe 415 passes through the receiving groove and is connected to the water tank 416 on the rear side, and an avoidance groove is opened on the outer side wall of the telescopic inner support rod 2 corresponding to the position of one of the annular water pipes 413, and an intermittent rotating assembly 417 is arranged in the avoidance groove.

[0035] See also Figure 2 and Figure 3 The intermittent rotating component 417 includes a fixed support plate 4171 fixedly connected to one of the annular water pipes 413, a tension spring fixedly connected between the fixed support plate 4171 and the accommodating groove, a toggle plate 4172 is contacted and connected to the rear side of the fixed support plate 4171, the toggle plate 4172 is fixedly connected to the left side of the rotating circular plate 4173 near the edge, the rear side of the rotating circular plate 4173 is fixedly connected to the output end of the motor, and the motor is fixedly connected to the outer wall of the telescopic inner support rod 2 through a motor seat.

[0036] Under the action of the tension spring, the fixed support plate 4171 is initially located in the middle of the receiving groove. When the expanded power pipe needs to be cooled, the motor is turned on, and the motor drives the rotating circular plate 4173 to rotate. The rotating circular plate 4173 drives the toggle plate 4172 to intermittently contact the fixed support plate 4171, which will reciprocate and push the fixed support plate 4171 to move back and forth in the receiving groove, and synchronously drive the annular water pipe 413 to rotate. The two annular water pipes 413 can reciprocate in the inner annular wall groove 411 under the connection of the docking water pipe 414, and the sprinkler head on the annular water pipe 413 reciprocates to rotate the power pipe. The tube performs cooling operation, the rotating annular water pipe 413 can increase the spraying range of the sprinkler head and enhance the cooling effect. Let me reiterate that the length of the flexible water pipe 415 is sufficient to adapt to the range of rotation of the annular water pipe 413, and the parts where the flexible water pipe 415 is connected to the water tank 416 and the annular water pipe 413 are rigidly connected. When the annular water pipe 413 is pulled, the normal water flow of the annular water pipe 413 will not be affected. The docking water pipe 414 can serve as a medium for water flow while connecting the two annular water pipes 413, so that the sprinkler heads on the two annular water pipes 413 can perform spraying operations at the same time.

[0037] See also Figure 1 and Figure 7 The resisting assembly 42 includes an L-shaped bracket 421 which is symmetrically fixedly connected to the outer wall of the telescopic inner support rod 2 at the front and rear ends, and a long gear 422 is rotatably connected between the L-shaped brackets 421. The right side of the long gear 422 is meshed with a vertical rack 423 near the front side. The front and rear sides of the vertical rack 423 are provided with limited vertical grooves 424, and a limited connecting rod 425 is slidably connected in the limited vertical groove 424. The other end of the limited connecting rod 425 is fixedly connected to the L-shaped bracket 421, and a rebound spring 426 is fixedly connected between the limited connecting rod 425 and the limited vertical groove 424. A baffle 427 is fixedly connected to the bottom end of the vertical rack 423, and a limited height plate 428 is fixedly connected to the top end of the vertical rack 423. A connecting groove is provided on the right side of the vertical rack 423, and a connecting rod 429 is slidably connected in the connecting groove. The other end of the connecting rod 429 is fixedly connected to the left side of the fixed seat 1.

[0038] When the long gear 422 rotates, it will engage the vertical rack 423 and move downward. The vertical rack 423 descends along the limit connecting rods 425 on the front and rear sides under the limit of the limit connecting rod 425. At the same time, the rebound spring 426 is in a stretched state, and the baffle 427 will move down to the right opening of the fixed ring tube 4 under the movement of the vertical rack 423. At this time, the lower side of the top of the height limiting plate 428 contacts the long gear 422, and the vertical rack 423 no longer moves downward. During the downward movement of the baffle 427, it plays a role of limiting and blocking the pressure maintaining component 5 on the right.

[0039] See also Figure 2 and Figure 6 The pressure-maintaining assembly 5 includes a fixed strut 51 fixed to the right side of the flaring drill bit 3, a fixed block 52 is fixedly connected to the top of the fixed strut 51, a connecting slide rod 53 is fixedly connected to the bottom of the fixed block 52, the connecting slide rod 53 is slidably connected to the left and right in the transverse groove provided in the semi-arc pressure-maintaining plate 54, a sliding groove 55 is provided between the front and rear transverse grooves on the semi-arc pressure-maintaining plate 54, the fixed strut 51 passes through the sliding groove 55, a moving arc block 56 is sleeved on the fixed strut 51, and the moving arc block 56 slides in the sliding groove 55, a first spring 57 is fixedly connected between the flaring drill bit 3 and the moving arc block 56, and a second spring 58 is fixedly connected between the sliding groove 55 and the moving arc block 56.

[0040] See also Figure 4 and Figure 6 The inner wall of the semi-arc pressure-maintaining plate 54 is provided with two paving grooves 551, and a pressure-maintaining strip 552 is elastically connected in the paving groove 551. The pressure-maintaining strip 552 corresponds to the shape of the expanded opening of the power pipe and has a certain elasticity so as to be more suitable for the pressure-maintaining operation of the power pipe.

[0041] Continue reading Figure 6 A push bar 521 is fixedly connected to the front side of the fixed block 52, and the push bar 521 is located on the rear side of the vertical rack 423. A gear 522 is integrally formed on the side of the push bar 521 away from the sliding groove 55, and a side of the push bar 521 close to the fixed block 52 is a straight plate structure.

[0042] When the flaring drill bit 3 moves to the left, the fixed block 52 will be driven to move to the left synchronously, and the pushing bar 521 on the left side of the fixed block 52 will mesh with the rear part of the long gear 422, driving the long gear 422 to rotate. When the left side of the semi-arc pressure-maintaining plate 54 passes through the circular through hole on the fixed seat 1, the long gear 422 meshes with the vertical rack 423 and moves downward. The baffle 427 at the bottom end of the vertical rack 423 will block the left side of the semi-arc pressure-maintaining plate 54, and the moving arc block 56 on the fixed support rod 51 moves in the sliding groove 55. The second spring 58 in the sliding groove 55 will be in a compressed state. At the same time, the flaring drill bit 3 continues to move to the left until it enters the power pipe for During the expansion operation, when the expansion operation of the electric pipe is completed, the long gear 422 is no longer meshed with the gear teeth 522 at the upper end of the push bar 521, and the long gear 422 is located at the straight plate part of the push bar 521. At this time, the vertical rack 423 will rebound to its original position under the action of the rebound spring 426, and the baffle 427 will move up synchronously and no longer block the left side of the semi-arc pressure maintaining plate 54. The semi-arc pressure maintaining plate 54 will move to the left under the action of the second spring 58, and correspondingly, the semi-arc pressure maintaining plate 54 will enter the fixed ring tube 4, and the upper and lower semi-arc pressure maintaining plates 54 will approach each other in the fixed ring tube 4 until a complete circle is formed, and the semi-arc pressure maintaining plate 54 will perform pressure maintaining operation on the expanded electric pipe.

[0043] Working principle: The electric power pipe to be expanded is sleeved on the telescopic inner support rod 2, and the electric power pipe is heated by an external heating device. After heating to the required temperature, the heating device is removed, and the hydraulic electric push rod on the rear side of the movable push plate 6 is started at the same time. The hydraulic electric push rod pushes the movable push plate 6 to move along the fixed limit rod 11 toward the fixed seat 1 until the expanding drill bit 3 is driven into the electric power pipe, and the telescopic inner support rod 2 is pushed to the left to expand the electric power pipe. During the expansion operation, the semi-arc pressure maintaining plate 54 will be blocked by the resisting component 42 on the right side of the fixed ring tube 4. On the other hand, when the flaring drill bit 3 completes the flaring operation, the long gear 422 and the gear tooth 522 will no longer mesh, and correspondingly, the baffle 427 will no longer block the semi-arc pressure maintaining plate 54. The semi-arc pressure maintaining plate 54 moves to the inner wall of the fixed ring tube 4 under the action of the second spring 58, and the semi-arc pressure maintaining plate 54 maintains the pressure on the expanded power pipe. At the same time, the spray assembly 41 is started to cool down the semi-arc pressure maintaining plate 54. At the same time, the flaring drill bit 3 and the pressure maintaining assembly 5 are withdrawn, and the spray assembly 41 continues to spray and cool down the expanded part of the power pipe to complete the final flaring operation.
