Description

Technical Field

[0001] The invention relates to the technical field of laying water supply and drainage pipes, and specifically proposes a water supply and drainage pipe laying construction equipment. Background Art

[0002] Water supply and drainage pipes are an indispensable part of buildings and urban infrastructure. They are responsible for transporting clean water and discharging sewage. Water supply and drainage pipes are usually made of durable and non-corrosive materials, such as PVC, PE, etc. The connection between water supply and drainage pipes made of PVC or PE is made by plugging. One end of the water supply and drainage pipe has a large diameter and the other end has a small diameter.

[0003] Existing technology has also proposed a pipeline laying construction plan. The Chinese utility model patent with authorization announcement number CN211649272U discloses a water conservancy water supply pipeline connection device. This water conservancy water supply pipeline connection device can fix the water supply pipeline on the pipeline connection device through a connecting piece, thereby facilitating the operation of the water supply pipeline. Through the adjustment device and the support member, the water supply pipeline can be moved and fixedly connected, and at the same time, a large amount of manpower can be saved, thereby making it more convenient to connect the water supply pipeline.

[0004] However, when laying and connecting pipelines in this pipeline laying construction method, it is usually difficult to quickly and accurately align the joints of the two pipelines because the pipeline placed in the groove is not concentrically aligned with the installed and fixed pipeline after clamping, thereby reducing the efficiency of the pipeline laying construction; and when connecting two pipelines that need to be plug-in connected, due to the provision of sealing rings and other sealing parts between the two, the friction is large, which makes it difficult to fully insert the two pipelines into place at one time, reducing the quality and efficiency of the pipeline laying construction.

DETAILED DESCRIPTION

[0033] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0034] In order to enable those skilled in the art to better understand the scheme of the present invention, the present invention is further described in detail below in conjunction with the accompanying drawings and specific embodiments.

[0035] See also Figure 1 A water supply and drainage pipe laying construction equipment, comprising: two fixed frames 1, both ends of the fixed frames 1 are equipped with inverted support legs 2, the support legs 2 are connected to the existing mobile equipment, the tops of the two fixed frames 1 are jointly equipped with guide rail seats 3, and the guide rail seats 3 are equipped with clamping and laying feeding mechanisms 4, one of the fixed frames 1 is equipped with a clamping and positioning mechanism 5, and the other fixed frame 1 is equipped with a supporting mechanism 6, the clamping and laying feeding mechanism 4 and the clamping and positioning mechanism 5 clamp two pipes 7 respectively, wherein the pipe 7 clamped by the clamping and positioning mechanism 5 is the pipe 7 after laying and fixing, hereinafter collectively referred to as pipe one, and the pipe 7 clamped by the clamping and laying feeding mechanism 4 is pipe two, both pipe one and pipe two are stepped structures with a large diameter at one end and a small diameter at the other end, and the large diameter end of pipe two is sleeved on the small diameter end of pipe one during laying construction.

[0036] See also Figure 1 , Figure 2 , Figure 3 and Figure 5 The clamping and laying feeding mechanism 4 includes an inverted C-shaped frame 40 whose horizontal section is slidably connected to the top of the guide rail seat 3. The two vertical sections of the inverted C-shaped frame 40 have receiving grooves 41 on their opposite surfaces. A sliding seat 43 is installed between the two receiving grooves 41 through a sliding support group 42. A clamping group 44 for clamping the pipe 7 is installed at the bottom of the sliding seat 43. A top alignment secondary feeding group 45 is arranged between the sliding seat 43 and the fixed frame 1 on which the clamping alignment mechanism 5 is installed.

[0037] When the two fixing frames 1 move downward, the top alignment secondary feeding group 45 contacts the top of pipe one, and at the same time, the top alignment secondary feeding group 45 also limits the top of pipe two when the clamping group 44 clamps pipe two. Thereafter, the top alignment secondary feeding group 45 cooperates with the clamping group 44 to clamp and fix pipe two, and the top alignment secondary feeding group 45 contacts the top of the small diameter section of pipe two. The existing equipment lifts the other end of pipe two along with the clamping group 44. At this time, pipe two is aligned with pipe one under the contact and limiting action of the top alignment secondary feeding group 45.

[0038] See also Figure 3 The clamping group 44 includes two guide grooves 440 opened at the bottom of the sliding seat 43, and an arc-shaped clamping plate 441 is slidably connected to the guide groove 440. A two-way hydraulic cylinder 442 is installed between the two guide grooves 440. The two ends of the two-way hydraulic cylinder 442 are respectively fixedly connected to the two arc-shaped clamping plates 441, and the top alignment secondary feeding group 45 is located between the two arc-shaped clamping plates 441.

[0039] The two-way hydraulic cylinder 442 drives the two arc-shaped clamping plates 441 to move toward the side wall of the second pipe, and the two arc-shaped clamping plates 441 cooperate with the top-aligned secondary feed group 45 therebetween to clamp the second pipe, so that the top of the second pipe is on the same horizontal line as the top of the first pipe. At this time, the axes of the second pipe and the first pipe are on the same horizontal plane, and when the two arc-shaped clamping plates 441 clamp the second pipe, the sliding support group 42 cooperates with the sliding seat 43 to move along with the clamping of the second pipe by the arc-shaped clamping plates 441, so that the two arc-shaped clamping plates 441 only need to clamp and fix the second pipe, and there is no need to push the second pipe to move radially along the second pipe by the clamping force when clamping the second pipe, which improves the convenience of clamping the second pipe and avoids the damage of the second pipe due to the large clamping force when clamping the second pipe, thereby shortening the service life of the second pipe.

[0040] See also Figure 3 and Figure 5 The sliding support group 42 includes a push plate 421 slidably connected in the receiving groove 41, and the push plate 421 is connected to the receiving groove 41 through a push spring 420. Balls are installed at both ends of the sliding seat 43 arranged along its length direction, and the balls at both ends are in rolling contact with the two push plates 421 respectively. The upper and lower end surfaces of the sliding seat 43 located in the receiving groove 41 are rotatably installed with rotating support rollers 422.

[0041] When the two arc-shaped clamps 441 clamp pipe 2, if pipe 2 is not exactly located between the two arc-shaped clamps 441, then after one of the arc-shaped clamps 441 first fits against the side wall of pipe 2, the two-way hydraulic cylinder 1 442 continues to drive the two arc-shaped clamps 441 to move. Due to the weight of pipe 2 itself blocking the arc-shaped clamp 441 that first fits against it, the sliding seat 43 moves under the clamping interaction force between the arc-shaped clamps 441 and pipe 2. The sliding seat 43 continues to move after squeezing the corresponding push springs 420 and push plates 421 along the two receiving grooves 41, so that the two arc-shaped clamps 441 only need to clamp and fix pipe 2. During the movement of the sliding seat 43, the supporting roller 422 is rotated to reduce the friction between the sliding seat 43 and the receiving groove 41 and improve the smoothness of the movement of the sliding seat 43.

[0042] See also Figure 1 and Figure 3The clamping alignment mechanism 5 includes two clamping arc plates 50 connected to the fixed frame 1 and symmetrically arranged along the length direction thereof. A clamping driving group 51 is installed on the fixed frame 1 to drive the clamping arc plates 50 to clamp the pipe 7. The two clamping arc plates 50 are provided with an alignment guide group 52 that pushes the sliding seat 43 to move along the radial direction of the pipe 7 when the sliding seat 43 clamps the pipe 7. The alignment guide group 52 pushes the sliding seat 43 to drive the pipe 7 to move and cooperates with the top alignment secondary feeding group 45 to align the center of the two pipes 7.

[0043] After the clamping and laying feeding mechanism 4 clamps and fixes the pipe 2, the clamping driving group 51 drives the two clamping arc plates 50 to clamp the pipe 1. When the clamping and moving movement is performed, the clamping arc plates 50 drive the alignment guide group 52 to cooperate with the sliding support group 42, thereby pushing the sliding seat 43 and the clamping group 44 to drive the pipe 2 to move horizontally and radially along the pipe 2, so that the pipe 2 is concentric with the pipe under the cooperation of the clamping and laying feeding mechanism 4 and the clamping alignment mechanism 5, so that the large diameter section of the pipe 2 is accurately sleeved on the outer wall of the small diameter end of the pipe 1, thereby improving the accuracy and laying efficiency of the laying construction of the pipe 7. After the pipe 2 is clamped by the clamping and laying feeding mechanism 4, the suspended pipe 2 is pushed to move horizontally along the radial direction of the pipe 2 by the clamping alignment mechanism 5, thereby easily pushing the sliding seat 43 to drive the pipe 2 to move, thereby improving the convenience of alignment between the pipe 2 and the pipe.

[0044] Then the supporting mechanism 6 is started, and the supporting mechanism 6 supports the two sides of the second pipe close to the bottom of the outer wall, and at the same time, the supporting mechanism 6 contacts and limits the side of the alignment guide group 52 away from the clamping arc plate 50, so that the alignment guide group 52 can always guide the axial feeding of the second pipe when the clamping laying feed mechanism 4 drives the second pipe to move horizontally along the length direction of the guide rail seat 3. At the same time, the supporting mechanism 6 can also support the second pipe during the movement of the second pipe, further improving the stability and accuracy of the axial movement of the second pipe, and when the external driving source 1 (such as a one-way hydraulic cylinder) drives the inverted frame 40 to drive the sliding seat 43, the clamping group 44 and the second pipe to move a certain distance, so that the large diameter section of the second pipe is sleeved After being installed on pipe one, the external driving source one stops moving, and the clamping driving group 51 drives the two clamping arc plates 50 away from one side wall of the pipe, and the clamping group 44 away from the side wall of pipe two. At this time, the top alignment secondary feeding group 45 cooperates with the sliding seat 43 and the clamping group 44 to resist the transition from the small diameter to the large diameter section of pipe two, and pushes pipe two to feed toward pipe one again. Under the action of the multi-stage feeding force of clamping, conveying and resisting, the large diameter section of pipe two is inserted into the small diameter section of pipe one and accurately plugged into place, thereby realizing the integrated function of clamping, fixing, feeding and alignment plug-in during the laying construction of pipe 7, which not only improves the convenience and efficiency of laying pipe 7, but also enables pipe two and pipe one to be quickly plugged into place.

[0045] See also Figure 1 and Figure 2 The clamping drive group 51 includes a guide slot 510 which is opened on the fixed frame 1 and passes through the upper and lower parts and is symmetrically arranged along its length direction. The upper end of the clamping arc plate 50 slides through the guide slot 510 and is then installed with a limit seat 511. The bottom of the limit seat 511 is installed with a roller (not shown in the figure) which is rollingly connected to the top of the fixed frame 1. The limit seat 511 cooperates with the roller to support the clamping arc plate 50. A two-way hydraulic cylinder 2 (not shown in the figure) is fixedly installed between the guide rail seat 3 and the fixed frame 1. The two telescopic ends of the two-way hydraulic cylinder 2 are inserted into the corresponding guide slots 510 and are connected to the clamping arc plate 50. The two clamping arc plates 50 are driven by the two-way cylinder 2 to clamp the pipeline 1.

[0046] See also Figure 1 , Figure 3 and Figure 6 The top alignment secondary feeding group 45 includes a spring groove 450 opened at the bottom of the sliding seat 43, and a limiting groove is opened at the bottom of the fixed frame 1 connected to the clamping arc plate 50. The spring groove 450 and the limiting groove are slidably connected to a top alignment plate 451 with a "J"-shaped structure. The width of the spring groove 450 is greater than the width of the top alignment plate 451. When the sliding seat 43 moves, the top alignment plate 451 does not move along the radial direction of the pipeline 7. The large diameter section of the pipeline 2 is located between the two vertical sections of the protrusion of the top alignment plate 451. The bottoms of the horizontal sections at both ends of the top alignment plate 451 are located on the same plane, and the bottom of the horizontal section of the top alignment plate 451 is installed with uniformly arranged friction reducing Roller one, a retracting spring rod 452 is installed in the spring groove 450, and a connecting strip slidably connected to the top alignment plate 451 is installed on the retracting spring rod 452. When the sliding seat 43 drives the retracting spring rod 452 and the connecting strip to move radially along the pipeline 7, the connecting strip slides on the top alignment plate 451 and always elastically retracts the top alignment plate 451. A fixed plate 454 slidably mounted on the guide rail seat 3 is installed on the side of the inverted C-shaped frame 40 away from the clamping arc plate 50. A secondary feeding drive source for driving the sliding seat 43 to move along the width direction of the inverted C-shaped frame 40 is provided on the fixed plate 454. A push assembly matching the top alignment plate 451 is installed on the arc clamping plate 441.

[0047] See also Figure 1 and Fig. 9 The push assembly includes a push plate 460 installed on the side of the arc clamping plate 441 close to the clamping arc plate 50. A receiving groove 461 is provided on the side of the push plate 460 close to the pipe 7. A blocking bar 462 is slidably connected to the receiving groove 461. The blocking bar 462 is connected to the receiving groove 461 through a compression spring 463.

[0048] The top alignment plate 451 is located at the bottom of the horizontal section between the two clamping arc plates 50 and contacts the top of pipe one. When the two arc-shaped clamping plates 441 clamp pipe two, the arc-shaped clamping plates 441 drive the abutment plate 460 to move toward the outer wall of pipe two. When the baffle 462 contacts the side wall of pipe two, the baffle 462 squeezes the compression spring 463 under the resistance of pipe two and enters the accommodating groove 461. At the same time, the two arc-shaped clamping plates 441 clamp pipe two and make the top of the small diameter section of pipe two contact with the bottom of the horizontal section where the top alignment plate 451 is located between the two arc-shaped clamping plates 441, thereby making the top of pipe two and the top of pipe one located on the same horizontal line.

[0049] Afterwards, the clamping alignment mechanism 5 cooperates with the supporting mechanism 6 to align and guide the pipe 2, so that the pipe 2 is concentric with the pipe. Then, when the external driving source 1 (such as a one-way hydraulic cylinder) drives the inverted frame 40 to drive the sliding seat 43, the arc clamping plate 441 and the pipe 2 to move, the top alignment plate 451 moves with the pipe 2 driven by the sliding seat 43, and always keeps guiding the axial feeding movement of the pipe 2 until the first feeding of the pipe 2 is completed.

[0050] When the second pipe is fed for the second time, the second feeding driving source (such as a one-way hydraulic cylinder) is started to push the sliding seat 43 to move along the receiving groove 41 toward the first pipe. During the process in which the sliding seat 43 drives the top alignment plate 451, the arc clamping plate 441, the abutment plate 460 and the baffle 462 to move along the axial direction of the second pipe, when the vertical part of the top alignment plate 451 close to the large diameter of the second pipe collides with the transition between the small diameter and the large diameter of the second pipe, the sliding seat 43 continues to move, and the top alignment plate 451 is at the large diameter of the second pipe. Under the blocking effect, the retracting spring rod 452 is pulled to extend. When the blocking bar 462 contacts the transition between the small diameter and the large diameter of pipe 2, the top alignment plate 451 contacts the inner wall of the spring groove 450 close to the fixed plate 454, and then the secondary feed drive source continues to push the sliding seat 43 to move. At this time, pipe 2 is fed toward pipe 1 for the second time under the thrust of the vertical section of the top alignment plate 451 and the two blocking bars 462, so that pipe 2 is connected to pipe 1 in place under the action of the multi-stage feed force.

[0051] See also Figure 1 and Figure 7 The supporting mechanism 6 includes two displacement grooves 60 opened at the bottom of the fixed frame 1 and symmetrically arranged along its length direction. A support seat 61 with an L-shape and an inclined surface at the top of the horizontal section is installed on the displacement groove 60. A two-way hydraulic cylinder 62 is installed between the two displacement grooves 60. The two ends of the two-way hydraulic cylinder 62 are respectively inserted into the corresponding displacement grooves 60 and connected with the corresponding support seat 61. The inclined surface of the support seat 61 is rotatably connected with a supporting member 63; the supporting member 63 is an inclined receiving roller.

[0052] After pipe 2 is clamped and aligned, bidirectional cylinder 3 drives two support seats 61 and receiving rollers to move toward pipe 2 until the two receiving rollers contact the side walls of pipe 2, thereby supporting pipe 2, and when pipe 2 moves axially, the receiving rollers support pipe 2 and rotate, reducing the friction between pipe 2 and the receiving rollers when it moves, and also further improving the stability and accuracy of the axial movement of pipe 2.

[0053] See also Figure 1 , Figure 6 and Figure 8 The alignment guide group 52 includes a guide plate 520 slidably connected to the side of the clamping arc plate 50 away from the pipe 7, and the side wall of the clamping arc plate 50 is provided with a rectangular groove 521 slidably connected to the guide plate 520. A return spring 522 is installed between the rectangular groove 521 and the guide plate 520. The guide plate 520 extends to the side wall of the arc clamping plate 441 away from the pipe 7. The opposite surfaces of the two guide plates 520 are rotatably installed with two anti-friction rollers 523 evenly arranged along their length direction. A support component for supporting the guide plate 520 is arranged between the guide plate 520 and the inverted frame 40, and a locking component is arranged between the guide plate 520 and the support seat 61.

[0054] See also Figure 1 , Figure 3 and Figure 4 The support assembly includes an L-shaped hook plate 540 installed on the side of the inverted U-shaped frame 40 away from the clamping arc plate 50, and the horizontal sections of the two L-shaped hook plates 540 are both facing the pipeline 7. A receiving slide groove 541 is provided at the top of the horizontal section of the L-shaped hook plate 540, and a guide groove 542 extending along its length direction is provided at the bottom of the guide plate 520. A slider 543 is slidably connected in the guide groove 542, and the lower end of the slider 543 is slidably connected to the receiving slide groove 541.

[0055] See also Figure 1 , Figure 3 , Figure 4 and Figure 7 The locking assembly includes a blocking groove 530 opened on the end surface of the support seat 61 near the clamping arc plate 50, the end of the guide plate 520 extends into the blocking groove 530, and the bottom of the guide plate 520 is rotatably connected to a roller 531, and the roller 531 is located between the L-shaped hook plate 540 and the clamping arc plate 50.

[0056] When the clamping arc plate 50 clamps pipe one, the clamping arc plate 50 drives the guide plate 520 to move. At this time, the slider 543 at the lower end of the guide plate 520 slides along the receiving slide groove 541, and pushes the arc clamping plate 441 to drive the sliding seat 43 to move along the receiving groove 41, thereby concentrically aligning pipe two with pipe one, so that the large diameter section of pipe two can be accurately mounted on the outer wall of the small diameter end of pipe one. First, align the center of pipe two with pipe one, and then start the supporting mechanism 6 to support pipe two, thereby improving the accuracy of the support seat 61 driving the receiving roller to support the outer wall of pipe two and reducing the probability of collision damage.

[0057] When the support seat 61 moves thereafter, the blocking groove 530 contacts and supports the end of the guide plate 520, thereby achieving a stable support and guiding effect for the guide plate 520 under the support of the blocking groove 530 and the L-shaped hook plate 540, and during the subsequent movement of the inverted U-shaped frame 40, the L-shaped hook plate 540 always supports the bottom of the guide plate 520.

[0058] Before the first feeding of pipe 2 is completed, the L-shaped hook plate 540 contacts the roller 531 and drives the guide plate 520 to move toward the clamping arc plate 50 through the roller 531. The guide plate 520 moves out of the blocking groove 530 and pulls the reset spring 522 to extend. Then, the two-way hydraulic cylinder 1 442 and the clamping drive group 51 are started at the same time, so that the arc clamping plate 441 is separated from the side wall of pipe 2, and the clamping arc plate 50 is separated from one side wall of the pipe, so that the top alignment secondary feeding group 45 can push pipe 2 to perform secondary feeding movement.

[0059] After the pipeline 1 and the pipeline 2 are laid and connected, the supporting mechanism 6 is first separated from the pipeline 2, and the top alignment secondary feeding group 45 and the inverted C-shaped frame 40 are reset again, so that the two guide plates 520 move between the two blocking grooves 530 to facilitate the next construction.

[0060] During operation, in the first step, the pipe 2 is clamped and fixed by cooperating with the top alignment secondary feeding group 45 and the clamping group 44. The top alignment secondary feeding group 45 contacts the top of the small diameter section of the pipe 2. At this time, the pipe 2 is aligned with the top of the pipe 1 under the contact and limiting action of the top alignment secondary feeding group 45.

[0061] In the second step, the clamping drive group 51 drives the two clamping arc plates 50 to clamp the pipe 1. When the clamping arc plate 50 moves, it drives the alignment guide group 52 to cooperate with the sliding support group 42, thereby pushing the sliding seat 43 and the clamping group 44 to drive the pipe 2 to move along the horizontal radial direction of the pipe 2, so that the pipe 2 is concentric with the pipe under the cooperation of the clamping laying feed mechanism 4 and the clamping alignment mechanism 5, so that the large diameter section of the pipe 2 can be accurately mounted on the outer wall of the small diameter end of the pipe 1, thereby improving the accuracy and laying efficiency of the pipe 7 laying construction.

[0062] The third step is to start the supporting mechanism 6. The supporting mechanism 6 supports the two sides of the pipe 2 close to the bottom of the outer wall. At the same time, the supporting mechanism 6 limits the side of the alignment guide group 52 away from the clamping arc plate 50, so that the alignment guide group 52 can always guide the axial feed of the pipe 2. At the same time, the supporting mechanism 6 can also support the pipe 2 during the movement of the pipe 2, further improving the stability and accuracy of the axial movement of the pipe 2.

[0063] In the fourth step, an external driving source 1 (such as a one-way hydraulic cylinder) drives the inverted frame 40 to drive the sliding seat 43, the clamping group 44 and the pipe 2 to move a certain distance, so that the large diameter section of the pipe 2 is sleeved on the pipe 1, and then the external driving source 1 stops moving, and the clamping driving group 51 drives the two clamping arc plates 50 away from one side wall of the pipe, and the clamping group 44 away from the side wall of the pipe 2. At this time, the top alignment secondary feeding group 45 cooperates with the sliding seat 43 and the clamping group 44 to contact the transition from the small diameter to the large diameter section of the pipe 2, and pushes the pipe 2 to feed toward the pipe 1 again. Under the action of the multi-stage feeding force of clamping, conveying and pushing, the large diameter section of the pipe 2 is inserted into the small diameter section of the pipe 1 and accurately plugged into place, thereby realizing the integrated function of clamping, fixing, feeding and alignment plug-in during the laying of the pipe 7, which not only improves the convenience and efficiency of laying the pipe 7, but also enables the pipe 2 and the pipe 1 to be quickly plugged into place.
