Description

Technical Field

[0001] The present invention relates to the technical field of manhole cover positioning and installation, and particularly relates to an intelligent positioning device for road manhole cover installation in engineering construction and a positioning method thereof. Background Art

[0002] At present, various pipelines for communication and sewage discharge and pipeline inspection wells need to be set during road paving. When laying pipelines, pipeline inspection wells need to be built in cooperation with the road. When laying the road surface cushion layer and the surface layer, due to the influence of the pipeline inspection wells, it is difficult for the road roller to construct around the well body. The area around the wellhead cannot be compacted simultaneously with the road surface. The area around the wellhead needs to be treated by manual ramming, resulting in insufficient compaction density of the soil layer around the wellhead and unable to meet the engineering quality requirements. During the extrusion of vehicles, there are differences in elastic expansion and contraction, which are likely to cause cracks around the road well. The wellhead is not pressure-resistant and will mostly collapse after a long time. To solve the above drawbacks, the best construction plan is to roll and form the cushion layers above the wellhead at one time to avoid multiple fillings. However, after the cushion layer above the wellhead is rolled, it is difficult to accurately locate the installation position of the manhole cover, resulting in difficulties in installing the manhole cover later.

[0003] Therefore, we have designed an intelligent positioning device for road manhole cover installation in engineering construction and a positioning method thereof to solve the above problems. Summary of the Invention

[0004] The purpose of the present invention is to solve the drawbacks in the prior art that the manhole covers around urban road surfaces are easily damaged and collapsed under conventional construction conditions, and it is impossible to accurately locate the position of the manhole cover after the road surface and each cushion layer are paved integrally at one time. An intelligent positioning device for road manhole cover installation in engineering construction and a positioning method thereof are proposed. The purpose is to optimize the construction process of urban road manhole cover installation, accurately and intelligently locate the position of the manhole cover, and realize the one-time overall laying and compaction of the road surface and each cushion layer to improve the defect that the road surface around the manhole cover on the urban road is easily damaged and collapsed.

The automatic drilling machine is fixedly installed on the upper end surface of the moving plate. The bearing plate is installed on the lower end surface of the device collar. The ejecting mechanism is fixedly installed on the upper end surface of the bearing plate, and the output end of the ejecting mechanism is fixedly installed on the lower end surface of the moving plate.

[0009] Further, both the moving plate and the bearing plate are circular plate structures. The fixing plate is a ring structure with a circular area dug in the middle. The outer circumferential surface of the fixing plate is fixed to the device collar through four support arms. The centers of the fixing plate, the moving plate and the bearing plate are located on the same axis direction. The fixing plate and the device collar are located on the same plane.

[0013] A positioning method for an intelligent positioning device for installing road inspection wells in engineering construction, the positioning method comprising the following steps:

[0014] S1. Pipe well masonry: Lay pipes in the excavated trench, and build a pipe inspection well at the planned point of the pipe laying line;

[0015] S2. Equipment assembly: Install the sealing plate on the upper end of the pipe inspection well, install the ejection mechanism on the upper end surface of the bearing plate, sleeved the moving plate on the restraining rod, install the output end of the ejection mechanism on the lower end surface of the moving plate, then install the automatic drilling machine on the upper end surface of the moving plate, and install the limit nut on the top of the restraining rod. Install the mounting cantilever of the bearing frame on the hanging ear of the sealing plate through the first bolt, so that the drill bit of the automatic drilling machine is aligned with the drilling groove of the sealing plate;

[0016] S3. Equipment debugging: After completing the setting and assembly in step S2, start the automatic drilling machine and the ejection mechanism successively through the remote control starting device, debug the working performance of the ejection mechanism and the automatic drilling machine, and check the power storage. After the equipment debugging is completed, install the sealing plate on the upper end surface of the pipe inspection well, and embed the wooden plug into the drilling groove of the sealing plate;

[0017] S4. Cushion laying and positioning cutting: Lay the road surface cushion above the sealing plate and the pipe inspection well and compact the cushion with a roller. Start the automatic drilling machine through the remote control starting device. When the automatic drilling machine drives the drill bit to rotate, then start the ejection mechanism. The output end of the ejection mechanism jacks up the moving plate, and the drill bit drills the wooden plug in the drilling groove and the road surface on the sealing plate. After the drill bit penetrates the sealing plate, the drilling groove guides the drilling direction of the drill bit. When the drill bit drills out of the road surface, take the position of the drill bit as the center and the radius of the sealing plate as the radius to divide the cutting area, and use a road surface cutting machine to cut the cutting area from top to bottom until it reaches the sealing plate;

[0018] S5. Manhole cover positioning: After removing the road surface layer and the sealing plate where the cutting area is located from the upper end of the pipe inspection well, complete the positioning work for the installation of the manhole cover.

[0020] After the drill bit exposes the upper surface of the cushion, further start the ejection mechanism so that the limit sleeve abuts against the lower surface of the sealing plate. Insert the insertion pin shaft into the hanging hole on the drill bit, and after sleeving the rotating shaft with the lifting hanging rope at both ends of the insertion pin shaft, install the second bolt to restrain and fix the rotating shaft. Hang the lifting hook of the lifting equipment on the lifting hanging rope, lift the lifting hanging rope upward to lift the drill bit, and lift the road surface, the sealing plate and the intelligent positioning device where the cutting area is located to expose the pipe inspection well, and complete the positioning work for the installation of the manhole cover.

[0021] Further, in S4, the speed at which the output end of the ejection mechanism jacks up the moving plate is 0.5 - 1.5 mm / s, the thrust of the ejection mechanism is 10 - 200 kg, and the stroke is 1 - 100 cm.

[0022] Compared with the prior art, the beneficial effects of the present invention are as follows:

[0023] By using the positioning method of the intelligent positioning device for road manhole cover installation in engineering construction proposed by the present invention, when the intelligent positioning device is installed on the inspection wellhead of the pipeline, during the laying of the roadbed cushion, there is no need to consider the influence of the pipeline inspection well on the cushion laying. After the cushion above and around the pipeline inspection well is uniformly laid and compacted, by using this intelligent positioning device and its positioning method, the wellhead position can be accurately located, laying a foundation for the subsequent manhole cover installation. At the same time, it effectively solves the defects in the existing construction technology that mechanical equipment such as rollers cannot compact the top and surrounding cushion and road surface of the pipeline inspection well simultaneously, resulting in insufficient compaction density of the cushion around the pipeline inspection well, and cracks, poor pressure resistance, and easy collapse are likely to occur around the road manhole cover.

Detailed implementation manners

[0031] The technical solutions in the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments.

[0032] Nowadays, cities are developing better and better, and municipal construction is becoming more and more important. Urban roads are the carriers of various underground pipeline infrastructure. Their particularity determines their complexity. Various municipal inspection wells are often the weak links of road quality and also the parts that are difficult to handle. Concave "navels", cracks and damages often appear at the positions of manhole covers on urban roads, which greatly affect driving safety, accelerate the damage of the road surface, and are also prone to traffic safety accidents. The main reason for the above problems is that the connection between the manhole cover of the urban road pipeline well and the road surface is not tight and flat. In the existing construction technology, when laying pipelines in municipal engineering, pipeline inspection wells need to be built in cooperation with the pipelines. When laying the roadbed cushion and surface layer, due to the influence of the pipeline inspection well, it is difficult for the road roller to construct around the well body. The area around the wellhead cannot be compacted at the same time as the road surface. The area around the wellhead needs to be treated by manual ramming, resulting in insufficient compaction density of the soil layer around the wellhead and unable to meet the engineering quality requirements. Laying around multiple wellheads multiple times will have the following disadvantages: Since it is difficult for the road roller to construct around the well body and the soil layer around the well body cannot be compacted at the same time as the road surface, the compaction density of the soil layer around the well body is insufficient and cannot meet the engineering quality requirements. During the extrusion of vehicles, there are differences in elastic expansion and contraction, which are prone to cracks around the road well. The wellhead is not pressure-resistant and will mostly collapse after a long time. If the cushions above and around the pipeline inspection well can be used as a whole with each cushion, laid and compacted at one time, and then the compacted cushions above the manhole cover are cut and removed to expose the installation points of the manhole cover, and then the manhole cover is installed, avoiding excavation and filling and secondary compaction of the road surface around the manhole cover during the installation of the manhole cover, it can well solve the problem that the road surface around the manhole cover is easily damaged and collapsed.

[0033] Embodiment 1:

[0034] This embodiment is used for paving road surfaces. Before the cushion layer is paved, the upper part of the pipeline inspection wellhead is closed by a sealing plate. After the integral paving of the cushion layer above the pipeline inspection wellhead, the pipeline inspection well is pressed under the road surface cushion layer, and it is impossible to accurately locate the position of the manhole cover. Therefore, an intelligent positioning device for installing road manhole covers in engineering construction is proposed. As shown in Figure 2 and Figure 4 shown, the intelligent positioning device 30 includes a sealing plate 31, a bearing frame 34, an automatic drilling machine 35 and an ejection mechanism 36. The sealing plate 31 is placed on the upper end surface of the pipeline inspection well 10. A drilling groove 311 is provided in the middle of the sealing plate 31, and a wooden plug is embedded in the drilling groove 311. The bearing frame 34 is installed on the lower side of the sealing plate 31. The automatic drilling machine 35 and the ejection mechanism 36 are both installed on the bearing frame 34. A drill bit 33 is installed at the output end of the automatic drilling machine 35. The drill bit 33 is perpendicular to the sealing plate 31 and points to the drilling groove 311. A restraint rod 346 is provided on the bearing frame 34. The lower end of the automatic drilling machine 35 is installed at the output end of the ejection mechanism 36, and the ejection mechanism 36 drives the automatic drilling machine 35 to move up and down along the restraint rod 346.

[0035] As shown in Figure 4 and Figure 5 shown, it should be noted that the sealing plate 31 is a circular plate structure made of steel plate. The diameter of the sealing plate 31 is the same as the outer diameter of the pipeline inspection well 10. Hanging ears 32 are evenly arranged around the center of the sealing plate 31. The bearing frame 34 is installed on the hanging ears 32. The drilling groove 311 is located at the center of the sealing plate 31. The drilling groove 311 is the drilling guiding point for the drill bit 33 at the output end of the automatic drilling machine 35 during drilling.

[0036] It is worth mentioning that the bearing frame 34 includes an installation cantilever 341, a device collar 342, a fixing plate 343, a moving plate 344 and a bearing plate 345. The installation cantilever 341 is used to install the bearing frame 34 on the sealing plate 31. Specifically, the upper end of the installation cantilever 341 is fixedly installed on the hanging ear 32 through a first bolt 312. The lower end of the installation cantilever 341 is sleeved on the device collar 342. The device collar 342 is a circular ring structure with a hollow middle. The fixing plate 343 is fixedly arranged in the hollow area in the middle of the device collar 342. The restraint rod 346 is installed on the fixing plate 343, and the restraint rod 346 is evenly arranged around the center of the fixing plate 343. A moving plate 344 is arranged at the upper end of the fixing plate 343. Through holes are opened at the positions of the moving plate 344 corresponding to the restraint rod 346, and the moving plate 344 is slidably arranged on the restraint rod 346 through the through holes. The automatic drilling machine 35 is fixedly installed on the upper end surface of the moving plate 344. The bearing plate 345 is installed on the lower end surface of the device collar 342. The ejection mechanism 36 is fixedly installed on the upper end surface of the bearing plate 345, and the output end of the ejection mechanism 36 is fixedly installed on the lower end surface of the moving plate 344.

[0037] In this embodiment, as shown inFigure 5 As shown in the figure, both the moving plate 344 and the bearing plate 345 are circular plate-like structures. To facilitate the free telescoping of the output end of the ejection mechanism 36, the fixed plate 343 is an annular structure with a circular area dug in the middle. The outer circumferential surface of the fixed plate 343 is fixed to the device collar 342 through four support arms. The centers of the fixed plate 343, the moving plate 344, and the bearing plate 345 are located on the same axis direction. The fixed plate 343 and the device collar 342 are located on the same plane. The output end of the ejection mechanism 36 passes through the hollow part of the fixed plate 343. To make the force of the ejection mechanism 36 on the moving plate 344 perpendicular to the plane where the moving plate 344 is located, it is necessary to ensure that the output end of the ejection mechanism 36 is fixedly installed at the center position of the middle of the moving plate 344, and the output end is perpendicular to the moving plate 344.

[0038] As a limiting function for the movement of the automatic drilling machine 35, to prevent the automatic drilling machine 35 installed on the moving plate 344 from detaching from the restraining rod 346, a limiting nut 347 for restricting the further upward movement of the moving plate 344 is threadedly connected to the upper end of the restraining rod 346. When the moving plate 344 moves to the limiting nut 347, the limiting nut 347 can prevent the moving plate 344 from moving further upward, thereby realizing the limiting function for the moving plate 344.

[0039] It is worth noting that as Figure 3 and Figure 6 shown, considering the problem of removing the road surface part above the pipeline inspection well 10 and the intelligent positioning device 30 after the drill bit 33 drills out the road surface cushion layer, in this embodiment, a lifting hole 331 is opened at the upper end of the drill bit 33. A limiting sleeve 336 is fixedly arranged at a position near the output end of the automatic drilling machine 35 at the lower end of the drill bit 33. The limiting sleeve 336 is a circular structure, and its diameter is larger than the diameter of the drilling groove 311. An insertion pin shaft 333 is passed through the lifting hole 331. Rotating shafts 334 are sleeved at both ends of the insertion pin shaft 333, and threaded lines are arranged at both ends of the insertion pin shaft 333 and second bolts 335 are installed. A lifting hanging rope 332 for lifting the drill bit 33 is fixedly connected to the rotating shaft 334. The lifting hanging rope 332 can adopt a steel wire rope.

[0040] In this embodiment, the ejection mechanism 36 is an institution with a free-telescoping output end. The ejection mechanism 36 can adopt any one of a hydraulic push rod, an electric lead screw, and an electric cylinder. Both the ejection mechanism 36 and the automatic drilling machine 35 are powered by a battery power supply method, and both are equipped with a remote control starting device. Through the remote control starting device, the start and stop of the ejection mechanism 36 and the automatic drilling machine 35 can be remotely controlled over a long distance. The remote start and stop control of the motor equipment is a technology that can be achieved in the prior art, and will not be described in detail in this embodiment.

[0041] The intelligent positioning device for installing road inspection wells in engineering construction proposed in this embodiment is installed on the sealing plate 31 at the upper end of the pipeline inspection well 10 through the bearing frame 34. The intelligent positioning device 30 includes an ejection mechanism 36 and an automatic drilling machine 35. The ejection mechanism 36 is used to apply a pressing force to the automatic drilling machine 35, so that the drill bit 33 on the automatic drilling machine 35 can generate a squeezing force on the road surface, thereby realizing the drilling operation on the road surface cushion layer laid in the area where the inspection well is located, determining the accurate position of the area where the inspection well is located, and cutting the area where the inspection well is located, providing a prerequisite for the subsequent installation of the inspection well.

[0042] Embodiment 2:

[0043] This embodiment introduces the positioning method of the intelligent positioning device for installing road inspection wells in Embodiment 1, solves the problem of being unable to accurately locate the installation position of the inspection well after the completion of the laying of the road surface cushion layer, realizes the optimization of the construction technology of urban road laying and inspection well installation, and improves the problem of easy damage and collapse around the inspection wells on the urban road surface. The positioning method includes the following steps:

[0044] S1. Pipe well masonry: Lay pipelines in the excavated trench, and build a pipeline inspection well 10 at the planned point position of the pipeline laying line.

[0045] S2. Equipment assembly: As Figure 1 shown, install the sealing plate 31 on the upper end of the pipeline inspection well 10, install the ejection mechanism 36 on the upper end surface of the bearing plate 345, sleeved the moving plate 344 on the restraining rod 346, install the output end of the ejection mechanism 36 on the lower end surface of the moving plate 344, then install the automatic drilling machine 35 on the upper end surface of the moving plate 344, and install the limit nut 347 on the top of the restraining rod 346. Install the installation cantilever 341 of the bearing frame 34 on the hanging ear 32 of the sealing plate 31 through the first bolt 312, so that the drill bit 33 of the automatic drilling machine 35 is aligned with the drilling groove 311 of the sealing plate 31.

[0046] S3. Equipment debugging: After completing the setting and assembly in Step S2, start the automatic drilling machine 35 and the ejection mechanism 36 respectively and successively through the remote control starting device, debug the working performance of the ejection mechanism 36 and the automatic drilling machine 35, and check the power storage capacity. After the equipment debugging is completed, install the sealing plate 31 on the upper end surface of the pipeline inspection well 10, and embed a wooden plug into the drilling groove 311 of the sealing plate 31.

[0047] S4. Cushion layer laying, positioning and cutting: As Figure 2As shown, a roadbed cushion is laid and compacted above the sealing plate 31 and the pipeline inspection well 10. Through the remote control starting device, the automatic drilling machine 35 is started. After the drill bit 33 of the automatic drilling machine 35 starts to rotate, the ejecting mechanism 36 is started. The output end of the ejecting mechanism 36 jacks up the moving plate 344. The drill bit 33 drills the wooden plug in the drilling groove 311 and the road surface on the sealing plate 31. After the drill bit 33 drills through the sealing plate 31, the drilling groove 311 guides the drilling direction of the drill bit 33. When the drill bit 33 drills out of the road surface, with the position of the drill bit 33 as the center and the radius of the sealing plate 31 as the radius, a cutting area 20 is demarcated. The road surface cutting machine is used to cut the cutting area 20 from top to bottom until reaching the sealing plate 31. In this step, to ensure that the ejecting mechanism 36 does not generate excessive jacking force on the drill bit 33 of the automatic drilling machine 35 and damage the structure of the drill bit 33, through a large number of experimental studies, the following safety data ranges are obtained: the speed at which the output end of the ejecting mechanism 36 jacks up the moving plate 344 is 0.5 - 1.5 mm / s, the thrust of the ejecting mechanism 36 is 10 - 200 kg, and the output end stroke is 1 - 100 cm. In the actual controlled drilling operation, the on-site staff can slowly and repeatedly control the moving plate 344 to drive the automatic drilling machine 35 to move up and down.

[0048] S5. Manhole cover positioning: As Figure 4 and Figure 6 shown, after the positioning cutting is completed, after removing the road surface layer where the cutting area 20 is located and the sealing plate 31 from the upper end of the pipeline inspection well 10, the specific removal steps are as follows: After the drill bit 33 drills through and exposes the roadbed cushion, further start the ejecting mechanism 36 to make the limit sleeve 336 abut against the lower surface of the sealing plate 31, then close the ejecting mechanism 36. Insert the insertion pin shaft 333 into the hanging hole 331 on the drill bit 33, and after sleeving the rotating shaft 334 with the lifting hanging rope 332 on both ends of the insertion pin shaft 333, install the second bolt 335 to restrain and fix the rotating shaft 334. Hang the lifting hook of the lifting equipment on the lifting hanging rope 332, lift the lifting hanging rope 332 upward to lift the drill bit 33, and lift the roadbed cushion, the sealing plate 31 and the intelligent positioning device 30 where the cutting area 20 is located, exposing the pipeline inspection well 10, thereby completing the positioning work for the installation of the manhole cover.

[0049] Through the above intelligent positioning method for the installation position of the manhole cover, when laying the road surface, there is no need to consider the influence of pipelines and pipeline wellheads on the laying of the cushion layer. The cushion layer above and around the wellhead can be laid and compacted in one go. By using this intelligent positioning device and its positioning method, the position of the wellhead can be accurately determined, providing feasibility for optimizing the existing road surface laying process, effectively solving the disadvantages in the prior art that it is difficult to construct around the well body by road roller machinery, the cushion layer above and around the wellhead cannot be compacted simultaneously with the cushion layer in other areas of the road surface in the same horizontal plane, and cracks and collapses are likely to occur around the road well, enabling each cushion layer of the road surface to maintain the same compaction density, improving the construction quality and compressive performance of the road surface around the manhole cover.

[0050] The above is only a preferred specific embodiment of the present invention, but the protection scope of the present invention is not limited thereto. Any person skilled in the art within the technical scope disclosed by the present invention, according to the technical solution and inventive concept of the present invention, makes equivalent substitutions or changes, and should be covered by the protection scope of the present invention.
