Description

Technical Field

[0001] This invention relates to the field of pipe splicing equipment technology, specifically a PVC pipe splicing device. Background Technology

[0002] PVC pipes, short for polyvinyl chloride pipes, have good tensile and compressive strength, can withstand certain pressure and tension, and have a smooth inner wall, resulting in low resistance to fluid flow. They also have excellent acid, alkali, and corrosion resistance, are unaffected by moisture and soil pH, and maintain stable performance in various harsh chemical environments. No anti-corrosion treatment is required during pipe laying. They are widely used in water supply pipes, drainage pipes, electrical conduits, cable conduits, and other applications, and hold a significant market share in the construction, municipal engineering, agricultural irrigation, and some industrial transportation sectors.

[0003] Some PVC pipes used in municipal engineering and agricultural irrigation projects are quite large. When connecting them, it is necessary to manually push the two pipes together. Because the pipes are large in size and heavy, this method is not only inefficient, but also labor-intensive, resulting in excessively long connection time and low overall project efficiency.

[0011] Preferably, the outer wall polishing assembly includes a first rotating disk connected to the output shaft, the first rotating disk having an outer wall polishing block and an outer wall wiping cotton embedded therein, and the first rotating disk having a chamfering cutter corresponding to the outer edge of the pipe.

[0012] Preferably, the inner wall polishing assembly includes a second rotating disk connected to the output shaft, and the second rotating disk has an inner wall polishing block and an inner wall wiping cotton embedded therein, which are in contact with the inner wall of the pipe.

[0015] (III) Beneficial Effects Compared with the prior art, the present invention provides a PVC pipe splicing device, which has the following advantages: 1. By setting up a first horizontal moving component and a clamping component, during use, the excavator uses the connecting component to lift the frame and places the clamping components on both sides of the pipe. The two clamping components are distributed on the sides of the pipes that need to be connected. Then, the third hydraulic cylinder works to drive the first clamping arm and the second clamping arm inward, so that the first clamping arm and the second clamping arm drive the self-expanding clamping block to fit against the outer wall of the pipe through the clamping plate and clamp the pipe. Then, the excavator uses the pipe to lift it off the ground. Then, the first horizontal moving component uses the hinge seat to drive the clamping component connected to it to move horizontally, so that the two clamping components move closer to each other, and the clamped pipes also move horizontally accordingly, realizing the purpose of automatically splicing and connecting the pipes without manual operation and intervention, which greatly improves work efficiency.

[0016] 2. By setting a self-tensioning clamping block, the self-tensioning clamping block is mainly composed of a wedge block that slides with the clamping plate. When the clamping component is pulled inward towards the center, the wedge block cannot move on its own because it is in contact with the outer wall of the pipe. The clamping plate will apply force to the wedge block by moving. At this time, after the wedge block is subjected to force, it will move inward by its own inclined surface, thereby squeezing the pipe and making it fit more tightly with the pipe. The return spring can use its own elasticity to drive the wedge block to return to its original position after the clamping work is completed.

[0017] 3. By setting up a grinding component, which is located below the second and third horizontal moving components, it can move horizontally in the X and Y axes. It is mainly driven by the second rotary oil cylinder and speed increaser. It can be connected to the original hydraulic system of the excavator. It is equipped with grinding and tightening components for the outer wall of the pipe and grinding components for the inner wall of the pipe. It can grind the inner and outer walls of the pipes that need to be connected, so as to remove the oxide layer and dirt of the pipes, increase the tightness of the pipes after connection, and the pipe connection is completed automatically without manual intervention.

Detailed Implementation

[0020] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0021] Please see Figure 1-11 A PVC pipe splicing device includes a frame 1, a connecting component 2 connected to an excavator boom on the frame 1, a slide rail 8 on the frame 1, a first horizontal moving component 3 on the slide rail 8, a hinge seat 10 under both the frame 1 and the first horizontal moving component 3, a clamping component 5 on the side of the hinge seat 10, a self-expanding clamping block 6 that fits against the pipe on the end face of the clamping component 5, the clamping component 5 includes a first clamping arm 501 and a second clamping arm 503 rotatably connected to the hinge seat 10, a third hydraulic cylinder 502 hinged to the side of the first clamping arm 501 and the second clamping arm 503, and a clamping plate 504 connected to the self-expanding clamping block 6 at the bottom of both the first clamping arm 501 and the second clamping arm 503, and a fixing pin 505 connected to the self-expanding clamping block 6 on the clamping plate 504. like Figure 3As shown, by setting the first horizontal moving component 3 and the clamping component 5, when in use, the excavator uses the connecting component 2 to lift the frame 1 and places the clamping component 5 on both sides of the pipe. The two clamping components 5 are distributed on the sides of the pipes that need to be connected. Then, the third hydraulic cylinder 502 works to drive the first clamping arm 501 and the second clamping arm 503 inward, so that the first clamping arm 501 and the second clamping arm 503 drive the self-expanding clamping block 6 to fit against the outer wall of the pipe through the clamping plate 504 and clamp the pipe. Then, the excavator lifts the pipe off the ground. Then, the first horizontal moving component 3 uses the hinge seat 10 to drive the clamping component 5 connected to it to move horizontally, so that the two clamping components 5 move closer to each other, and the clamped pipes move horizontally accordingly, realizing the purpose of automatically splicing and connecting the pipes without manual operation and intervention, which greatly improves work efficiency. In addition, when installing pipes, two sets of clamping components 5 can be used to clamp the same pipe and an excavator can be used to put it into a pre-dug pipe trench. Then, another pipe can be placed in the same way. This can also be used for pre-placement of pipes, further reducing the labor intensity of manual labor. Moreover, this method eliminates the need for manual labor to enter the pipe trench, reducing the risk of manual work.

[0022] The self-tensioning clamping block 6 includes a wedge block 601 that is horizontally slidably connected to the clamping plate 504. The side of the wedge block 601 is set as an arc surface that fits against the outer wall of the pipe, and anti-slip stripes 602 are provided in the arc surface. A sliding pin 603 is provided on the wedge block 601, and a return spring 604 is provided on the sliding pin 603. The other end of the return spring 604 is connected to the fixed pin 505. like Figure 4 As shown, by setting a self-tensioning clamping block 6, the self-tensioning clamping block 6 is mainly composed of a wedge block 601 that slides with the clamping plate 504. When the clamping component 5 is pulled inward towards the center, the wedge block 601 cannot move because it is attached to the outer wall of the pipe. The clamping plate 504 will apply force to the wedge block 601 by moving. At this time, after the wedge block 601 is subjected to force, it will move inward by its own inclined surface, thereby squeezing the pipe and making it fit more tightly with the pipe. The return spring 604 can use its own elasticity to drive the wedge block 601 to return to its original position after the clamping work is completed. The clamping force is proportional to the force when the pipe is connected.

[0023] The connecting component 2 includes a connecting frame 201 mounted on the frame 1, a connecting plate 202 rotatably mounted on the connecting frame 201, a first rotary cylinder 203 that is connected to the connecting frame 201 in a transmission manner on the connecting plate 202, and a connecting pin 204 that is connected to the excavator boom on one side of the connecting plate 202. like Figure 2As shown, by setting a first rotary cylinder 203 and a connecting pin 204, two connecting pins 204 are provided, and their size and specifications comply with industry excavator requirements. Furthermore, it can be connected to an excavator equipped with a quick connector, so that the excavator only needs to connect the equipment when pipe connection is required. The first rotary cylinder 203 can be driven by the excavator's original hydraulic system to adjust the direction of the frame 1, making it more convenient to use.

[0024] The first horizontal moving component 3 includes a first sliding frame 301, a first sliding seat 302 that slides with the slide rail 8 under the first sliding frame 301, a first front hinge plate 303 on the side of the first sliding frame 301, a first hydraulic cylinder 304 inside the first front hinge plate 303, and a first rear hinge plate 305 connected to the frame 1 at the tail end of the first hydraulic cylinder 304. like Figure 3 As shown, by setting a first sliding frame 301, which is mounted on the slide rail 8 via a first slide block 302, it can move horizontally under the drive of the first hydraulic cylinder 304. This allows the clamping component 5 to be used to connect the pipe. Furthermore, by setting the first sliding frame 301 at the top, the first slide block 302 is under pressure, making the movement more stable and increasing its load-bearing capacity without changing the specifications of the first slide block 302.

[0025] The slide rail 8 is provided with a second horizontal moving part 4, and a third horizontal moving part 9 is provided below the second horizontal moving part 4. The side of the third horizontal moving part 9 is provided with a grinding part 7 for processing the inner and outer surfaces of the pipe. The grinding part 7 includes a speed increaser 701 connected to the third horizontal moving part. The input end of the speed increaser 701 is provided with a second rotary cylinder 702, and the output end of the speed increaser 701 is provided with an output shaft 705 that passes through both sides. The two ends of the output shaft 705 are provided with an outer wall grinding assembly 703 and an inner wall grinding assembly 704. like Figure 5 As shown, by setting up a grinding component 7, which is located under the second horizontal moving component 4 and the third horizontal moving component 9, it can move horizontally in the X and Y axes. It is mainly driven by the second rotary oil cylinder 702 and speed-changing machine 701. It can be connected to the original hydraulic system of the excavator. On both sides, there are outer wall grinding components 703 and inner wall grinding components 704 for the pipe. It can perform grinding work on the inner and outer walls of the pipes that need to be connected, so as to remove the oxide layer and dirt of the pipes, increase the tightness of the pipes after connection, and complete the work automatically without manual intervention.

[0026] The second horizontal moving component 4 includes a second sliding frame 401, a second sliding seat 402 that slides with the slide rail 8 under the second sliding frame 401, a second front hinge plate 403 on the side of the second sliding frame 401, a second hydraulic cylinder 404 inside the second front hinge plate 403, and a second rear hinge plate 405 connected to the frame 1 at the tail end of the second hydraulic cylinder 404. like Figure 5 and Figure 6 As shown, by setting a second sliding frame 401 and a second sliding seat 402, the second sliding frame 401 is connected to the slide rail 8 via the second sliding seat 402 at the bottom, so that the third horizontal moving part 9 and the grinding part 7 can move horizontally, so that the grinding part 7 can be fitted and inserted into the pipe, and the pipe does not need to be moved when grinding is performed.

[0027] The third horizontal moving component 9 includes a suspension frame 901 connected to the speed increaser 701. The suspension frame 901 is provided with rollers 902 hanging on both sides of the second sliding frame 401. The side of the suspension frame 901 is provided with a fourth hydraulic cylinder 903. The tail end of the fourth hydraulic cylinder 903 is provided with a support plate 904 connected to the second sliding frame 401. like Figure 5 and Figure 7 As shown, by setting a fourth hydraulic cylinder 903 and a roller 902, the roller 902 is suspended on both sides of the second sliding frame 401. The grinding component 7 can be supported by the suspension frame 901, while the fourth hydraulic cylinder 903 can drive the suspension frame 901 to move horizontally. When grinding, the grinding component 7 is aligned with the pipe. When the pipe is connected, the grinding component 7 is moved away.

[0028] The outer wall grinding assembly 703 includes a first rotating disk 7031 connected to the output shaft 705. The first rotating disk 7031 is fitted with an outer wall grinding block 7032 and an outer wall wiping cotton 7033 that are in contact with the outer wall of the pipe. The first rotating disk 7031 is provided with a chamfering cutter 7034 that corresponds to the position of the outer edge of the pipe. like Figure 8 As shown, by setting the outer wall grinding block 7032 and the outer wall wiping cotton 7033, the first rotating disk 7031 can be rotated quickly by the output shaft 705, and drive the outer wall grinding block 7032 to grind the outer wall of the pipe, so as to remove the oxide layer and surface dirt of the outer wall of the pipe. At the same time, the outer wall wiping cotton 7033 on the other side wipes away the powder generated by grinding, so as to avoid a large amount of powder affecting the adhesion of the adhesive. The chamfering cutter 7034 set on the first rotating disk 7031 can chamfer the pipe end, making the pipe insertion smoother and avoiding the problem that the pipe edge is too sharp and easily scratches the inner wall of the pipe to the other pipe.

[0029] The inner wall polishing assembly 704 includes a second rotating disk 7041 connected to the output shaft 705, and an inner wall polishing block 7042 and an inner wall wiping cotton 7043 that are in contact with the inner wall of the pipe are embedded in the second rotating disk 7041. like Figure 9 As shown, by setting the inner wall grinding block 7042 and the inner wall wiping cotton 7043, the first rotating disk 7031 can be rotated quickly by the output shaft 705, and drive the inner wall grinding block 7042 to grind the inner wall of the pipe, so as to remove the oxide layer and surface dirt of the inner wall of the pipe. At the same time, the inner wall wiping cotton 7043 on the other side wipes away the powder generated by grinding, so as to avoid a large amount of powder affecting the adhesion of the adhesive. It should also be noted that large PVC pipes are pre-expanded at one end during production, so the pipes can be directly connected during installation without the need for pipe fittings. In addition, existing mature technology allows for the pre-installation of sealing rings in the pipes at the factory, thus eliminating the need for installing sealing rings.

[0030] The inner wall grinding assembly 704 is equipped with an adhesive application component 11. The adhesive application component 11 includes a fixing plate 1101 connected to the inner wall of the second rotating disk 7041 and a storage battery 1105. The fixing plate 1101 is equipped with an electromagnetic telescopic rod 1102 electrically connected to the storage battery 1105. The electromagnetic telescopic rod 1102 is equipped with a fixing frame 1103. The side of the fixing frame 1103 is equipped with an adhesive application wheel set 1104 that fits against the inner wall of the pipe. like Figure 10 As shown, by setting up an electromagnetic telescopic rod 1102 and a storage battery 1105, the electromagnetic telescopic rod 1102 can extend and retract by generating magnetism when the electromagnet is energized. When it is necessary to apply glue, the glue application wheel assembly 1104 is moved outward to fit against the inner wall of the pipe. The glue application is achieved by using the movement of the second rotating disk 7041. The storage battery 1105 can supply power to the electromagnetic telescopic rod 1102. Furthermore, a remote control unit is set up to simplify the laying of wired circuits and ensure that it does not affect the operation of the second rotating disk 7041.

[0031] The glue-applying wheel assembly 1104 includes a glue storage hopper 11041 connected to a fixed frame 1103, a rotating glue roller 11042 rotatably mounted on the glue storage hopper 11041, and a threaded fixing groove 1143 connected to a glue tank at the bottom of the glue storage hopper 11041. like Figure 11As shown, a glue storage hopper 11041 is provided, on which a rotating glue roller 11042 is rotatably mounted. The bottom of the hopper is connected to a glue tank via a threaded fixing groove 1143. When the hopper 11041 is inverted, glue from the glue tank flows into the hopper and contacts the rotating glue roller 11042. As the rotating glue roller 11042 rotates, it applies glue to the inner wall of the pipe. After the rotating glue roller 11042 is in contact with the inner wall of the pipe, it rotates on its own along with the rotation of the second rotating disk 7041. When the hopper 11041 is upright, excess glue flows into the glue tank. This achieves automatic feeding while simultaneously allowing the rotating glue roller 11042 to apply glue, and also prevents the glue from solidifying due to prolonged contact with the outside environment.

[0032] Working principle: The clamping component 5 is placed on both sides of the pipe to be connected. Then, the third hydraulic cylinder 502 drives the clamping plate 504 to rotate through the first clamping arm 501 and the second clamping arm 503, so that the clamping plate 504 clamps the pipe with the self-tensioning clamping block 6. Then, the pipe is lifted to a certain height. Then, the third horizontal moving component 9 aligns the grinding component 7 with the pipe. With the cooperation of the second horizontal moving component 4, the grinding component 7 grinds the inner and outer walls of the pipe to be connected. Then, PVC pipe special glue is applied to the inside of the pipe. Then, the grinding component 7 is removed. The first horizontal moving component 3 uses the clamping component 5 to drive the pipe at one end to move, so that the pipes are connected, realizing the purpose of automatic grinding, glue application and connection of PVC pipe.

[0033] The above are merely specific embodiments of the present invention, but the technical features of the present invention are not limited thereto. Any simple changes, equivalent substitutions, or modifications made based on the present invention to solve essentially the same technical problems and achieve essentially the same technical effects are all covered within the protection scope of the present invention.
