Description

Technical Field

[0001] The invention relates to the technical field of urban water pipeline construction, and in particular to pressure-based assembled urban water pipeline construction erection auxiliary equipment. Background Art

[0002] Urban water pipelines are an indispensable part of the urban pipe network system, which can effectively guarantee the domestic water supply of urban residents. During the installation of water pipelines, independent pipes need to be spliced ​​and fixed. Therefore, it is necessary to use auxiliary installation devices during the construction process to support and support the pipes. However, the existing auxiliary installation devices for urban water pipeline construction still have some shortcomings.

[0003] For example, a protective auxiliary device for laying a natural gas pipeline with publication number CN201811122371.1 can effectively clamp the natural gas pipeline under the action of the movable clamp and the screw by setting a fixed clamp, fully preventing the swing of the natural gas pipeline from causing wear on its outer surface. By setting a second spring, it can effectively prevent the movable clamp and the fixed clamp from clamping the natural gas pipeline with excessive clamping force, thereby preventing the natural gas pipeline from being damaged. However, it still needs to manually adjust the screw during use to fix the pipeline.

[0004] Another example is the oil pipeline connection support device with publication number CN201910483344.5, which can clamp and fix oil pipelines of different diameters by cooperating with the pipeline bracket. After the two oil pipelines are clamped and fixed by two pipeline clamps and two pipeline brackets, the two pipeline clamps and the two pipeline brackets can be controlled by a control mechanism to dock and fix the two oil pipelines, so that the inner sides of the two oil pipelines are pressed together, which is convenient for sealing and fixing by sealing rings in subsequent processes. However, it only realizes the limited docking between the pipelines. During use, an external sealing connection device is still required to perform subsequent operations on the pipelines. It is cumbersome to use and has certain defects in use.

[0005] Therefore, we proposed a pressure-based assembled urban water pipeline construction erection auxiliary equipment to solve the above-mentioned problems. Summary of the invention

[0006] The purpose of the present invention is to provide a pressure-based assembled urban water pipeline construction erection auxiliary equipment to solve the problem raised by the above background technology that the erection auxiliary equipment for water pipeline construction on the market is inconvenient to automatically fix and transport the pipeline during use and is inconvenient to directly complete the sealing splicing during the pipeline docking process.

[0007] To achieve the above-mentioned purpose, the present invention provides the following technical solution: a pressure-based assembled urban water pipeline construction erection auxiliary equipment, comprising:

[0008] 2 sets of brackets, which support and transport the pipeline body through roller mechanisms arranged on the lower surface thereof, wherein a rack is arranged on the inner side of the bracket, and a lifting block is arranged on the upper end of the rack, and a gear is connected to the internal shaft of the bracket, and the pipeline body is placed above the lifting block;

[0009] 2 sets of clamps, axially connected to both sides of the bracket;

[0010] A bracket is integrally arranged on the outer side of the gear, an adjustment seat is arranged on the upper end of the bracket, and a slider is movably arranged on the inner side of the adjustment seat;

[0011] A first connecting sleeve, as a pipe connecting component, is arranged above the adjusting seat, the inner side shaft of the first connecting sleeve is connected with a movable block, the inner wall of the first connecting sleeve is embedded with a first airbag, and the outer wall of the first connecting sleeve is embedded with a second airbag;

[0012] A second connecting sleeve, also serving as a pipe connecting component, is arranged above another group of adjusting seats, a clamping groove is provided on the inner wall of the second connecting sleeve, and a third air bag is arranged inside the clamping groove;

[0013] A sealing airbag, as a sealing member, embedded and installed on the outer walls of the first connecting sleeve and the second connecting sleeve;

[0014] The magnetic block is slidably connected to the inner side of the lower end of the bracket, and the outer side of the lower end of the bracket is axially connected to a positioning plate for positioning.

[0015] Preferably, the rack and the bracket form a telescopic structure, and the rack is meshingly connected to the gear, and a first pull rope that plays a traction linkage role is connected between the shaft end of the gear and the clamp, and the clamp is an arc-shaped structure.

[0016] By adopting the above technical solution, the rack can be moved downward under the action of the pipeline's own gravity, so that the rack and the gear are meshed and connected, so that the gear drives the symmetrically distributed clamps to automatically clamp the pipeline through the first pull rope, thereby preventing the pipeline from falling during transportation.

[0017] Preferably, a reset spring providing reset elastic force is connected between the inner wall of the adjustment seat at the upper end of the bracket and the slider, and the two groups of sliders are respectively integrated with the first connecting sleeve and the second connecting sleeve, and the first connecting sleeve and the second connecting sleeve are both gap-matched with the pipeline body.

[0018] By adopting the above technical solution, when the bracket drives the first connecting sleeve and the second connecting sleeve to rotate, the elastic sliding of the first connecting sleeve and the second connecting sleeve can prevent the first connecting sleeve and the second connecting sleeve from colliding and getting stuck with the pipeline body, so that the first connecting sleeve and the second connecting sleeve are horizontally connected with the pipeline body.

[0019] Preferably, the movable block is evenly distributed on the inner side of the first connecting sleeve, and the first connecting sleeve and the second connecting sleeve form a nested structure, and the upper and lower surfaces of the movable block are arc-shaped structures that are perpendicular to each other, and a first torsion spring is connected between the movable block and the inner wall of the first connecting sleeve.

[0020] By adopting the above technical solution, the movable block can be made to rotate elastically under the impact of water flow. At the same time, the arc-shaped structure on the surface of the movable block can reduce the flow diameter of the first connecting sleeve, thereby increasing the water pressure at the movable block, so that the movable block can fit tightly against the first connecting sleeve and the second connecting sleeve.

[0021] Preferably, an arc-shaped positioning block is provided on the outer wall of the movable block, and the positioning block and the slot form a snap-fit ​​structure, and frosted blocks are evenly provided on the mating side surfaces of the positioning block and the first connecting sleeve and the second connecting sleeve.

[0022] By adopting the above technical solution, the rotating movable block can automatically snap the positioning block into the slot, and then use the water pressure to splice and self-lock the first connecting sleeve and the second connecting sleeve, and the movable block can be reset by stopping the water supply, which is convenient for the later disassembly and maintenance of the pipeline.

[0023] Preferably, the sealing airbag is connected to the first airbag and the third airbag respectively, and the first airbag is connected to the second airbag, and the second airbag is in a circular ring structure.

[0024] By adopting the above-mentioned technical solution, when the movable block rotates, the first airbag and the third airbag can be squeezed at the same time, so that the gas inside the two airbags enters the second airbag and the sealing airbag respectively, so that the second airbag and the sealing airbag automatically expand and deform, so that the second airbag and the sealing airbag can seal the pipeline body, the first connecting sleeve and the second connecting sleeve.

[0025] Preferably, the sealing airbag is in a hollow truncated cone structure, and the large-diameter end of the sealing airbag faces the first connecting sleeve and the second connecting sleeve.

[0026] By adopting the above technical solution, when the sealing airbag expands, a force toward the first connecting sleeve and the second connecting sleeve can be applied to the pipeline body, thereby further improving the installation stability of the pipeline body.

[0027] Preferably, the magnetic block and the bracket form a telescopic structure, and the magnetic poles of the magnetic blocks on the inner side of the adjacent bracket are opposite.

[0028] By adopting the above technical solution, when the two groups of brackets are close to each other to complete the docking of the first connecting sleeve and the second connecting sleeve, the two groups of magnetic blocks will slide and adsorb on each other, thereby realizing the splicing and assembly of the brackets.

[0029] Preferably, a second torsion spring providing a reset force is connected between the shaft end of the positioning plate and the bracket, and a conical thorn that can penetrate into the soil is provided on the lower surface of the positioning plate, and the shaft end of the positioning plate is connected to the magnetic block by a second pull rope.

[0030] By adopting the above technical solution, when adjacent brackets are spliced, the positioning plate can rotate synchronously under the magnetic force of the magnetic block, so that the positioning plate can automatically pierce the cone into the ground, thereby achieving positioning and fixing of the bracket.

[0031] Compared with the prior art, the beneficial effects of the present invention are as follows: the pressure-based assembled urban water pipeline construction erection auxiliary equipment can realize the transportation and splicing of pipelines by utilizing its split structure, and can utilize the water pressure during the water delivery process to perform high-seal splicing and self-locking on the pipe fittings, and can realize automatic positioning during the assembly process, thereby maintaining the support stability of the pipeline;

[0032] 1. A lifting block, a clamp and a bracket are provided. By hoisting and placing the pipeline to be erected on the lifting block, the lifting block can make the rack and the gear mesh and connect under the action of the gravity of the pipeline itself, thereby driving the clamp to automatically clamp the pipeline. At the same time, the brackets on the outside of the two groups of brackets will respectively drive the first connecting sleeve and the second connecting sleeve to automatically connect and assemble with the two ends of the pipeline, thereby facilitating the subsequent connection and erection of the pipeline;

[0033] 2. A bracket, a magnetic block and a positioning plate are provided. By moving the bracket, the pipeline can be moved and adjusted, so that two sets of adjacent pipelines can be spliced ​​together. At this time, the first connecting sleeve and the second connecting sleeve at one end of the adjacent pipeline can be sleeved and assembled. At the same time, the magnetic block will slide, fit and adsorb under the action of magnetic force, and then pull the positioning plate to rotate automatically, so as to realize the automatic positioning and fixation of the assembled bracket;

[0034] 3. A first connecting sleeve, a second connecting sleeve and a movable block are provided. When the pipeline is in use, the movable blocks evenly distributed on the inner side of the first connecting sleeve will rotate under the impact of water flow and make the positioning block automatically snap into the slot, thereby realizing the self-locking splicing of the first connecting sleeve and the second connecting sleeve. The water flow aperture at the movable block is reduced, resulting in increased water pressure, thereby avoiding the resetting of the movable block. At the same time, the second airbag and the sealing airbag can be expanded and deformed during the rotation of the movable block, thereby effectively improving the sealing between the pipeline body, the first connecting sleeve and the second connecting sleeve, and effectively improving the functionality and practicality of the device.

[0044] See also Figure 1-7 The present invention provides a technical solution: an assembled urban water pipeline construction auxiliary equipment based on pressure, including a bracket 1, a rack 2, a lifting block 3, a gear 4, a first pull rope 401, a clamp 5, a pipeline body 6, a bracket 7, an adjustment seat 8, a slider 9, a reset spring 901, a first connecting sleeve 10, a second connecting sleeve 11, a movable block 12, a positioning block 1201, a first torsion spring 1202, a frosting block 1203, a first airbag 13, a second airbag 14, a slot 15, a third airbag 16, a sealing airbag 17, a magnetic block 18, a positioning plate 19, a second pull rope 1901, a second torsion spring 1902 and a cone thorn 1903.

[0047] The bracket 7 is integrally arranged on the outer side of the gear 4, an adjustment seat 8 is arranged on the upper end of the bracket 7, and a slider 9 is movably arranged on the inner side of the adjustment seat 8;

[0048] A first connecting sleeve 10, as a pipe connecting component, is arranged above the adjusting seat 8, the inner side shaft of the first connecting sleeve 10 is connected with a movable block 12, and the inner wall of the first connecting sleeve 10 is embedded with a first airbag 13, and the outer wall of the first connecting sleeve 10 is embedded with a second airbag 14;

[0049] The second connecting sleeve 11, also serving as a pipe connecting component, is arranged above another set of adjusting seats 8. A slot 15 is provided on the inner wall of the second connecting sleeve 11, and a third air bag 16 is provided inside the slot 15.

[0050] The sealing airbag 17 is embedded and installed on the outer wall of the first connecting sleeve 10 and the second connecting sleeve 11 as a sealing member;

[0051] The magnetic block 18 is slidably connected to the inner side of the lower end of the bracket 1, and the outer side of the lower end of the bracket 1 is axially connected to a positioning plate 19 for positioning.

[0052] The rack 2 and the bracket 1 form a telescopic structure, and the rack 2 is meshed with the gear 4. A first pull rope 401 for traction linkage is connected between the shaft end of the gear 4 and the clamp 5, and the clamp 5 is an arc-shaped structure.

[0053] A reset spring 901 providing a reset elastic force is connected between the inner wall of the adjustment seat 8 at the upper end of the bracket 7 and the slider 9, and the two groups of sliders 9 are respectively integrated with the first connecting sleeve 10 and the second connecting sleeve 11. At the same time, the first connecting sleeve 10 and the second connecting sleeve 11 are both clearance-matched with the pipeline body 6.

[0054] like Figure 1 and Figure 4 As shown, the pipeline to be erected is hoisted and placed above the two groups of brackets 1, so that the two groups of brackets 1 support the two ends of the pipeline respectively. At this time, the lifting block 3 will drive the rack 2 and the bracket 1 to perform telescopic movement under the action of the pipeline's own gravity, so that the rack 2 and the gear 4 are meshed and connected, so that the clamp 5 is pulled to rotate by the first pull rope 401, thereby realizing automatic clamping of the pipeline. At the same time, the gear 4 will drive the bracket 7 and the adjustment seat 8 to rotate synchronously, so that the first connecting sleeve 10 and the second connecting sleeve 11 are automatically connected and assembled with the two ends of the pipeline through telescopic movement.

[0055] The movable block 12 is evenly distributed on the inner side of the first connecting sleeve 10, and the first connecting sleeve 10 and the second connecting sleeve 11 form a nested structure, and the upper and lower surfaces of the movable block 12 are arc-shaped structures that are perpendicular to each other. At the same time, a first torsion spring 1202 is connected between the movable block 12 and the inner wall of the first connecting sleeve 10.

[0056] The outer wall of the movable block 12 is provided with an arc-shaped positioning block 1201 , and the positioning block 1201 and the card slot 15 form a clamping structure, and the mating side surfaces of the positioning block 1201 and the first connecting sleeve 10 and the second connecting sleeve 11 are evenly provided with frosting blocks 1203 .

[0057] The sealing airbag 17 is connected to the first airbag 13 and the third airbag 16 respectively, and the first airbag 13 is connected to the second airbag 14, and the second airbag 14 is in a circular ring structure.

[0058] The sealing airbag 17 is in a hollow truncated cone structure, and the end of the sealing airbag 17 with a larger diameter faces the first connecting sleeve 10 and the second connecting sleeve 11 .

[0059] like Figure 2-3 and Figure 5-7As shown, when the pipeline system is in use, the movable block 12 will rotate under the impact of water flow, so that the movable block 12 drives the positioning block 1201 on its outside to automatically snap into the slot 15. Since the surface of the movable block 12 is an arc-shaped structure, the flow rate of water is accelerated when passing through its surface, thereby generating a large water pressure, so that the movable block 12 fits tightly between the first connecting sleeve 10 and the second connecting sleeve 11, thereby realizing self-locking and splicing of the first connecting sleeve 10 and the second connecting sleeve 11. At the same time, after the movable block 12 rotates, it will squeeze the first airbag 13 and the third airbag 16, thereby causing the second airbag 14 and the third airbag 16 to expand and deform. At this time, the second airbag 14 and the third airbag 16 can automatically and efficiently block and seal the joints between the pipeline body 6, the first connecting sleeve 10 and the second connecting sleeve 11, thereby effectively improving the connection sealing of the pipeline.

[0060] The magnetic block 18 and the bracket 1 form a telescopic structure, and the magnetic poles of the magnetic blocks 18 on the inner side of the adjacent brackets 1 are opposite.

[0061] A second torsion spring 1902 providing a reset force is connected between the axial end of the positioning plate 19 and the bracket 1, and a cone thorn 1903 that can penetrate into the soil is provided on the lower surface of the positioning plate 19, and the axial end of the positioning plate 19 is connected to the magnetic block 18 through a second pull rope 1901.

[0062] like Figure 1 As shown, when the two groups of brackets 1 are close to each other and spliced, the magnetic block 18 will slide along the bracket 1 under the action of magnetic force, so that the two groups of magnetic blocks 18 fit and adsorb each other. At the same time, during the sliding process of the magnetic block 18, the positioning plate 19 will be pulled by the second pull rope 1901 to rotate synchronously, so that the positioning plate 19 automatically inserts the outer cone thorn 1903 into the ground, thereby realizing the stable assembly and positioning of the bracket 1, thereby providing stable auxiliary support for the pipeline.

[0063] Working principle: When using the pressure-based assembled urban water pipeline construction erection auxiliary equipment, first, Figure 1-7As shown, the pipeline body 6 is hoisted and placed above the lifting block 3. At this time, the clamp 5 will automatically clamp it under the action of the gravity of the pipeline. At this time, the two groups of brackets 1 can support the two ends of the pipeline body 6. At the same time, the first connecting sleeve 10 and the second connecting sleeve 11 will be respectively connected with the two ends of the pipeline body 6. Then the bracket 1 is moved so that the first connecting sleeve 10 and the second connecting sleeve 11 on the outside of the two adjacent pipeline bodies 6 are connected and assembled. At this time, the two groups of magnetic blocks 18 slide and adsorb under the action of magnetic force, and then pull the positioning plate 19 to rotate to pierce the cone thorn 1903 into the ground, thereby fixing the bracket 1. When water is transported inside the pipeline, the movable block 12 will rotate so that the positioning block 1201 is stuck in the card slot 15, thereby realizing the self-locking and splicing of the first connecting sleeve 10 and the second connecting sleeve 11. At the same time, the second airbag 14 and the third airbag 16 will efficiently seal the joints between the pipeline body 6, the first connecting sleeve 10 and the second connecting sleeve 11, thereby completing a series of work.
