Description
Technical Field
[0001] This application relates to the field of water supply and drainage construction technology, and in particular to a construction device and method for water supply and drainage engineering in building construction. Background Technology
[0002] Currently, water supply and drainage are indispensable in the construction process. They are mainly used for transporting and distributing industrial water and domestic drinking water, as well as collecting, transporting and discharging industrial wastewater, domestic water and rainwater.
[0003] In related technologies, the pipes of building water supply and drainage systems are usually spliced together from several pipes. During construction, trenches are usually excavated first, and then the pipes to be installed are hoisted into the trench using hoisting equipment such as cranes. Then, the pipes to be installed are moved by the hoisting equipment with the help of the personnel, so that the spigot end of the pipe to be installed is inserted into the socket end of the already installed pipe. After the splicing is completed, the trench is backfilled to complete the laying of the water pipe network.
[0004] Regarding the aforementioned technologies, the pipes themselves are quite heavy. Currently, when splicing pipes, a large amount of manpower is usually required to move and splice them, resulting in low pipe laying efficiency. Therefore, there is room for improvement. Summary of the Invention
[0005] To improve the efficiency of pipeline laying, this invention provides a construction device and method for building water supply and drainage engineering.
[0006] The present invention provides a construction device for water supply and drainage engineering in building construction, which adopts the following technical solution:
[0007] A construction device for water supply and drainage engineering in building construction includes a forward advancing device and a clamping device. The forward advancing device is connected to a lifting assembly that drives the clamping device to rise and fall. The clamping device includes a driving component, a clamping assembly, and a linkage assembly. The driving component and the clamping assembly are both connected to the lifting assembly. The clamping assembly is connected to the driving component. At least two sets of clamping assemblies are provided. Each pair of adjacent clamping assemblies is connected to a linkage assembly to achieve synchronous movement of at least two clamping assemblies. The clamping assembly closest to the installed pipe is connected to a positioning device for locating the position of the installed pipe. A control device that drives the positioning device to move closer to the pipe is provided between the positioning device and the clamping assembly. The control device is connected to the clamping assembly and is connected to a pushing device that pushes the pipe to be installed to move.
[0008] By adopting the above technical solution, during pipeline construction in drainage projects, the construction device is erected above the trench. The lifting assembly is activated, bringing the clamping assembly closer to the pipe to be installed. The drive mechanism is then activated, and through a linkage component, at least two sets of clamping assemblies move synchronously, clamping the pipe to be installed. While the clamping device is holding the pipe, it drives the control device. The positioning device positions the already installed pipe. After positioning, the pushing device is activated, pushing the pipe to be installed closer to the already installed pipe until they are joined, improving pipe joining efficiency. The forward movement device drives the clamping assembly, positioning device, and pushing device along the length of the trench, completing the pipe laying and further improving laying efficiency.
[0009] Preferably, the lifting assembly includes a hydraulic cylinder and a lifting plate. The hydraulic cylinder is connected to the forward device, the lifting plate is connected to the hydraulic cylinder, and the driving component is fixedly connected to the lifting plate. The clamping assembly includes a bidirectional lead screw, a first slider, a second slider, a first clamping plate, and a second clamping plate. The lifting plate has a first groove matching the first slider and a second groove matching the second slider. The length directions of the first groove and the second groove are parallel to the length direction of the bidirectional lead screw. The bidirectional lead screw passes through the first groove and the second groove. One end of the bidirectional lead screw is rotatably connected to the lifting plate, and the other end of the bidirectional lead screw passes through the lifting plate and is connected to the driving component.
[0010] The first slider is located in the first groove, and the second slider is located in the second groove. Both the first slider and the second slider are sleeved on the bidirectional lead screw. The first slider and the second slider are threadedly connected to the bidirectional lead screw. The first clamping plate is connected to the first slider, and the second clamping plate is connected to the second slider, so as to realize that the first clamping plate and the second clamping plate move closer or further away from each other.
[0011] By adopting the above technical solution, the hydraulic cylinder is activated, which drives the lifting plate to move vertically. When the clamping component needs to clamp the pipe, the driving component drives the bidirectional lead screw to rotate. While the bidirectional lead screw is rotating, it drives the first slider and the second slider to move closer to each other or further away from each other. The first slider drives the first clamping plate to move, and the second slider drives the second clamping plate to move. Therefore, the first clamping plate and the second clamping plate move closer to each other or further away from each other. When the first clamping plate and the second clamping plate move closer to each other, they clamp the pipe to be installed. When the first clamping plate and the second clamping plate move further away from each other, they release the pipe.
[0012] Preferably, the sidewalls of the first clamping plate and the second clamping plate that are close to each other are rotatably connected with ball bearings.
[0013] By adopting the above technical solution, when the pipe to be installed is moved by the pushing device, the ball bearings reduce the wear between the pipe to be installed and the first clamping plate and the second clamping plate, thereby increasing the service life of the first clamping plate and the second clamping plate.
[0014] Preferably, the positioning device includes positioning plates, at least two of which are provided. The positioning plates are respectively connected to the first clamping plate or the second clamping plate, and the at least two positioning plates are respectively located on both sides of the installed pipe, and the positioning plates abut against the side wall of the installed pipe.
[0015] By adopting the above technical solution, when the first clamping plate and the second clamping plate approach each other to clamp the pipe, the first clamping plate and the second clamping plate both drive the positioning plate to move. When the first clamping plate and the second clamping plate clamp the pipe, the two positioning plates just abut against the pipe, accurately positioning the installed pipe.
[0016] Preferably, the positioning device further includes a positioning block, and the control device is provided in two sets, with the two sets of control devices respectively corresponding to the first slider and the second slider. The control device is connected to the corresponding first slider or second slider, and the control device includes a connecting rod, a fixing rod, a fixing block, and a second control rod. The connecting rod is connected to the corresponding first slider or second slider, the length direction of the fixing rod is parallel to the length direction of the groove, the fixing rod is connected to the connecting rod, the fixing block is fixedly connected to the fixing rod, and the fixing block is located at the end of the fixing rod near the installed pipe. One end of the second control rod is rotatably connected to the fixing block, and the positioning block is rotatably connected to both second control rods.
[0017] By adopting the above technical solution, when the first slider and the second slider approach each other, the first slider or the second slider drives the connecting rod to move, the connecting rod drives the fixed rod to move, the two fixed rods approach each other, the fixed rod drives the fixed block to move, the two fixed blocks approach each other, the fixed block drives the second control rod to move, and the ends of the two second control rods approaching the fixed blocks approach each other, the other ends of the second control rods drive the positioning block to move downwards until the first clamping plate and the second clamping plate clamp the pipe, at which point the positioning block abuts against the installed pipe. When the first slider and the second slider move away from each other, the two fixed rods move away from each other, the two fixed blocks move away from each other, and the first control rod drives the positioning block to move upwards, away from the installed pipe.
[0018] Preferably, the control device further includes a sliding block and a first control rod. The sliding block is sleeved on the corresponding fixed rod and slidably connected to the fixed rod. One end of the first control rod is rotatably connected to the sliding block, and both first control rods are connected to the pushing device.
[0019] By adopting the above technical solution, when the first slider and the second slider approach each other, the fixed rod drives the sliding block to move. When the two sliding blocks approach each other, the sliding block drives the first control rod to move. When one end of the two first control rods approaches the sliding block, the other end of the first control rod drives the pushing device to move. When the first clamping plate and the second clamping plate clamp the pipe, the pushing device has moved to a height that can push the pipe to be installed.
[0020] Preferably, the pushing device includes a push rod and a driving assembly. The push rod is connected to the driving assembly, which drives the push rod to push the pipe to be installed closer to the installed pipe. The push rod is rotatably connected to both of the first control rods, and the driving assembly is connected to the lifting plate.
[0021] By adopting the above technical solution, the second control rod drives the push rod to move. When the first clamping plate and the second clamping plate clamp the pipe, the push rod has moved to a height that can push the pipe to be installed. Then the drive assembly is activated, and the drive assembly drives the push rod to push the pipe to be installed close to the installed pipe until the pipe to be installed is spliced with the installed pipe.
[0022] Preferably, the drive assembly includes a second motor, a drive screw, a drive block, and a telescopic rod. The second motor is connected to the lifting plate. The lifting plate has a third sliding groove that matches the drive block. The length direction of the third sliding groove is parallel to the length direction of the groove. The drive screw is disposed in the third sliding groove. The length direction of the drive screw is parallel to the length direction of the third sliding groove. One end of the drive screw is rotatably connected to the lifting plate, and the other end passes through the lifting plate and is fixedly connected to the second motor. The drive block is sleeved on the drive screw and threadedly connected to the drive screw. One end of the telescopic rod is fixedly connected to the drive block, and the other end is fixedly connected to the push rod.
[0023] By adopting the above technical solution, the second motor is started, which drives the drive screw to rotate. The drive screw drives the drive block to move along the drive screw, the drive block drives the telescopic rod to move, the telescopic rod drives the push rod to move, and the push rod pushes the pipe to be installed. The third groove restricts the sliding direction of the drive block.
[0024] Preferably, the forward movement device includes a fixed plate, support legs, and rollers. Multiple support legs are provided, and the support legs are located on both sides of the groove length direction. The top end of the support leg is fixedly connected to the fixed plate, and the bottom end is fixedly connected to the roller.
[0025] By adopting the above technical solution, once a pipe is installed or during pipe splicing, the fixing plate can be pushed and the rollers can move along the length of the trench.
[0026] This invention also provides a construction method for a building construction water supply and drainage engineering construction device, including the following steps:
[0027] S1. Construction preparation: Excavate a trench in the construction area for the pipeline to be buried, and then place the pipeline to be installed on the ground on one side of the trench.
[0028] S2. Place the first section of pipe: hoist the first section of pipe into the trench using hoisting equipment;
[0029] S3. Placement of construction equipment: Use hoisting equipment to erect the construction equipment on the trench, with the support legs located on both sides of the trench length.
[0030] S4. Pipe splicing: Place the pipes to be installed in the trench in sequence, start the lifting assembly to lower the lifting plate, and clamp the pipes by the clamping device. At this time, the control device drives the positioning device to position the previous installed pipe, and at the same time drives the pushing device to approach the pipe to be installed. After the positioning device determines the position of the pipe to be installed, the pushing device is started. The pushing device pushes the pipe until the pipe to be installed is spliced with the installed pipe.
[0031] S5. Assembly complete: Push the roller to roll and repeat step S4 until all pipes are assembled.
[0032] By adopting the above technical solution, after the trench is dug, the pipes to be installed are placed in the trench in sequence, and then the first pipe is installed. The construction device is then set up on the trench, and the lifting assembly is activated. The lifting assembly moves the lifting plate up and down in the vertical direction, bringing the clamping device close to the pipe. The clamping device is then activated and clamps the pipe. At this time, the clamping device drives the control device to move, and the control device drives the positioning device and the pushing device to move simultaneously. The positioning device moves close to the installed pipe and positions the installed pipe. Then the pushing device pushes the pipe to be installed close to the installed pipe until the pipe to be installed is spliced with the installed pipe. The above operation is repeated until the entire pipeline is laid, which improves the efficiency of pipeline laying.
[0033] In summary, the present invention has the following beneficial effects:
[0034] During the construction of drainage pipelines, the construction equipment is erected above the trench. The lifting component is activated, which moves the clamping component closer to the pipeline to be installed. The drive component is then activated, and through the linkage component, at least two sets of clamping components move synchronously. When at least two sets of clamping components are clamping the pipeline to be installed, the clamping device drives the control device to move. The control device drives the positioning device and the pushing device to move and approach the pipeline. The positioning device positions the already installed pipeline. After the positioning device completes the positioning, the pushing device is activated, which pushes the pipeline to be installed closer to the already installed pipeline until the pipeline to be installed is spliced with the already installed pipeline, thus improving the pipeline splicing efficiency.

[0041] The present invention will be further described in detail below with reference to the accompanying drawings.
[0042] On the one hand, this application discloses a construction device for water supply and drainage engineering in building construction, referring to... Figure 1 and Figure 2The system includes a forward-moving device 1, a lifting assembly, a clamping device 4, a control device 7, a positioning device, and a pushing device 9. The forward-moving device 1 is mounted on the trench and is used to move the construction equipment. The lifting assembly is connected to the forward-moving device 1, and the clamping device 4 is connected to the lifting assembly. The lifting assembly is used to lift the clamping device 4, and the clamping device 4 is used to clamp the pipe to be installed. The control device 7 is located between the clamping device 4 and the positioning device, and is also located between the clamping device 4 and the pushing device 9. The control device 7 is connected to the positioning device, the clamping device 4, and the pushing device 9. The control device 7 is used to move the positioning device and the pushing device 9 closer to the pipe to be installed. The positioning device is used to position the already installed pipe. The pushing device 9 is connected to the lifting assembly and is used to push the pipe to be installed to join the already installed pipe. The positioning device can quickly position the already installed pipe, and then the pushing device 9 pushes the pipe to be installed to join the already installed pipe, improving the efficiency of pipe laying.
[0043] Reference Figure 2 The forward movement device 1 includes a fixed plate 11, support legs 12, and rollers 13. The fixed plate 11 is rectangular, and four support legs 12 are vertically arranged symmetrically on both sides of the trench length direction. The top of each support leg 12 is fixedly connected to the fixed plate 11, and the bottom is fixedly connected to the rollers 13. The four support legs 12 are located at the four corners of the fixed plate 11. When a pipe is installed or during pipe splicing, the fixed plate 11 can be pushed, and the rollers 13 can move along the length direction of the trench.
[0044] Reference Figure 2 A lifting assembly is fixedly connected to a fixed plate 11. The lifting assembly includes hydraulic cylinders 2 and a lifting plate 3. Four hydraulic cylinders 2 are fixedly connected and are fixedly connected to the top of the fixed plate 11. The drive shaft of the hydraulic cylinder 2 passes through the fixed plate 11 and is fixedly connected to the lifting plate 3. The lifting plate 3 is cuboid in shape, and the four hydraulic cylinders 2 are located at the four corners of the lifting plate 3. When the hydraulic cylinders 2 are activated, they drive the lifting plate 3 to move vertically.
[0045] Reference Figure 3 The clamping device 4 includes a driving component, a clamping assembly 42, and a linkage assembly 43. To achieve the same purpose, the driving component can be a hydraulic motor, a first motor 41, etc. In this embodiment, the first motor 41 is selected. A mounting plate is fixedly connected to the side wall of the lifting plate 3, and the first motor 41 is fixedly connected to the top of the mounting plate.
[0046] Reference Figure 3Two sets of clamping assemblies 42 are arranged along the length of the groove. One set of clamping assemblies 42 includes a bidirectional lead screw 421, a first slider 422, a second slider 423, a first connecting rod 424, a first clamping plate 425, a second connecting rod 426, and a second clamping plate 427. The length direction of the bidirectional lead screw 421 is perpendicular to the length direction of the groove. One end of the bidirectional lead screw 421 extends into the lifting plate 3, and the other end is fixedly connected to the first motor 41. When the clamping assembly 42 needs to clamp the pipe, the first motor 41 drives the bidirectional lead screw 421 to rotate.
[0047] Reference Figure 3 The lifting plate 3 has a first sliding groove 31 and a second sliding groove 32, the length directions of which are parallel to the length direction of the bidirectional lead screw 421. There are two first sliding grooves 31 and two second sliding grooves 32, forming a group of one first sliding groove 31 and one second sliding groove 32. Within the same group, the first sliding groove 31 and the second sliding groove 32 correspond to a set of clamping assemblies 42. A bidirectional lead screw 421 passes through both the first sliding groove 31 and the second sliding groove 32 within the same group, and is rotatably connected to the lifting plate 3.
[0048] Reference Figure 3 The first slider 422 and the second slider 423 are both sleeved on the bidirectional lead screw 421, and are threadedly connected to the bidirectional lead screw 421. The first slider 422 and the second slider 423 are symmetrically arranged on the bidirectional lead screw 421. The first slider 422 matches the first slide groove 31, and the second slider 423 matches the second slide groove 32. The first slider 422 and the second slider 423 slide against the lifting plate 3.
[0049] As the bidirectional lead screw 421 rotates, it causes the first slider 422 and the second slider 423 to move closer to or further away from each other. The first groove 31 restricts the sliding direction of the first slider 422, and the second slider 423 restricts the sliding direction of the second slider 423.
[0050] Reference Figure 3 The first connecting rod 424 is fixedly connected to the first slider 422, and the first clamping plate 425 is fixedly connected to the bottom end of the first connecting rod 424. The second connecting rod 426 is fixedly connected to the second slider 423, and the second clamping plate 427 is fixedly connected to the bottom end of the second connecting rod 426. Both the first clamping plate 425 and the second clamping plate 427 are arc-shaped plates, and their centers are close to each other. Multiple balls 5 are rotatably connected to the adjacent sidewalls of the first clamping plate 425 and the second clamping plate 427, and the balls 5 are evenly distributed on the first clamping plate 425 or the second clamping plate 427.
[0051] The first slider 422 drives the first clamping plate 425 to move, and the second slider 423 drives the second clamping plate 427 to move. Therefore, the first clamping plate 425 and the second clamping plate 427 move closer to each other or further apart. When the first clamping plate 425 and the second clamping plate 427 move closer together, they clamp the pipe to be installed. When the first clamping plate 425 and the second clamping plate 427 move further apart, they release the pipe. The ball bearing 5 facilitates the movement of the pipe to be installed.
[0052] Reference Figure 3 The linkage assembly 43 includes sprockets and a chain. There are two sprockets, each corresponding to one of the two bidirectional lead screws 421. The bidirectional lead screws 421 are fixedly connected to the sprockets. The chain is sleeved on the two sprockets and meshes with both sprockets. The linkage assembly 43 realizes the movement of the two bidirectional lead screws 421.
[0053] Reference Figure 3 and Figure 4 Two sets of control devices 7 are symmetrically arranged. One set of control devices 7 is connected to the first slider 422, and the other set of control devices 7 is connected to the second slider 423. The control device 7 includes a connecting rod 71, a fixing rod 72, a sliding block 73, a first control rod 74, a fixing block 75, and a second control rod 76. The connecting rod 71 is fixedly connected to either the first slider 422 or the second slider 423.

The positioning device includes a positioning plate 6 and a positioning block 8. Two positioning plates 6 are provided, each corresponding to a first clamping plate 425 and a second clamping plate 427 respectively. One end of each positioning plate 6 is fixedly connected to either the first clamping plate 425 or the second clamping plate 427. The adjacent sidewalls of the positioning plates 6 abut against the installed pipe, and the distance between the two positioning plates 6 is the same as the outer diameter of the installed pipe. The positioning block 8 is rotatably connected to both second control rods 76.
[0057] When the first clamping plate 425 and the second clamping plate 427 clamp the pipe, the two positioning plates 6 are in contact with the pipe, and the positioning block 8 is in contact with the installed pipe. The positioning plates 6 and the positioning block 8 provide multi-directional positioning for the pipe, which improves the accuracy of positioning.
[0058] Reference Figure 4 The pushing device 9 is located at the end of the lifting plate 3 away from the installed pipe. The pushing device 9 includes a push rod 91 and a drive assembly 92, and the push rod 91 is rotatably connected to both first control rods 74.
[0059] Reference Figure 4 The drive assembly 92 includes a second motor 921, a drive screw 922, a drive block 923, and a telescopic rod 924. The second motor 921 is fixedly connected to the lifting plate 3. A third sliding groove 33 is provided on the lifting plate 3, and the length direction of the third sliding groove 33 is parallel to the length direction of the groove. The drive screw 922 is disposed within the third sliding groove 33, and the length direction of the drive screw 922 is parallel to the length direction of the third sliding groove 33. One end of the drive screw 922 is rotatably connected to the lifting plate 3, and the other end passes through the lifting plate 3 and is fixedly connected to the second motor 921.
[0060] Reference Figure 4 The drive block 923 is sleeved on the drive screw 922 and threadedly connected to the drive screw 922. The third slide groove 33 matches the drive block 923, and the drive block 923 slides against the lifting plate 3. One end of the telescopic rod 924 is fixedly connected to the drive block 923, and the other end is fixedly connected to the push rod 91.
[0061] The second control lever 76 drives the push rod 91 to move. When the first clamping plate 425 and the second clamping plate 427 clamp the pipe, the push rod 91 has moved to a height that can push the pipe to be installed. Then the second motor 921 is started. The second motor 921 drives the drive screw 922 to rotate. The drive screw 922 drives the drive block 923 to move along the drive screw 922. The drive block 923 drives the telescopic rod 924 to move. The telescopic rod 924 drives the push rod 91 to move. The push rod 91 pushes the pipe to be installed.
[0062] The operating principle of this application is as follows: When splicing pipes, the construction device is set up on the trench, and the fixed plate 11 is pushed to move the device to a suitable position. The hydraulic cylinder 2 is activated, and the hydraulic cylinder 2 drives the lifting plate 3 to descend. The lifting plate 3 drives the clamping device 4, the positioning device, and the pushing device 9 to descend until the clamping device 4 clamps the pipe to be installed. The first motor 41 is activated, and the first motor 41 drives the bidirectional lead screw 421 to rotate. The bidirectional lead screw 421 drives the first slider 422 and the second slider 423 to move closer or further apart. The first slider 422 drives the first connecting rod 424 to move, and the second slider 423 drives the second connecting rod 426 to move. The first connecting rod 424 and the second connecting rod 426 move closer or further apart. The first connecting rod 424 drives the first clamping plate 425 to move, and the second connecting rod 426 drives the second clamping plate 427 to move. The first clamping plate 425 and the second clamping plate 427 move closer together to clamp the pipe to be installed.
[0063] When the first slider 422 and the second slider 423 move, they drive the connecting rod 71 to move. The connecting rod 71 drives the fixed rod 72 to move. The fixed rod 72 drives the sliding block 73 and the fixed block 75 to move. The sliding block 73 drives the first control rod 74 to move. The fixed block 75 drives the second control rod 76 to move. The two first control rods 74 move closer to each other, causing the push plate to move closer to the pipe to be installed. The two second control rods 76 move closer to each other, causing the positioning block 8 to move closer to the installed pipe. When the first clamping plate 425 and the second clamping plate 427 move, the positioning plate 6 moves. When the first clamping plate 425 and the second clamping plate 427 clamp the pipe to be installed, the positioning block 8 and the positioning plate 6 abut against the top of the installed pipe, and the push rod 91 descends to the position to push the pipe to be installed.
[0064] After the positioning block 8 and positioning plate 6 position the pipeline, the second motor 921 is started.
