Description

Technical Field

[0001] The invention relates to the technical field of road engineering, and in particular to a non-destructive rapid repair machine and a construction process for an urban road inspection well. Background Art

[0002] With the rapid growth of my country's economic construction, the construction of road engineering infrastructure has developed rapidly in recent years. By the end of 2018, my country has built a total mileage of more than 1.2 million kilometers of urban roads, ranking among the top in the world. After years of rolling by vehicles, the inspection wells on municipal roads will have slight settlement, loose manhole covers, dents, abnormal noises and other defects, which need to be repaired. At present, the repair of municipal road inspection wells is done by manual milling, which is slow and causes damage to the road surface, increasing the maintenance cost. Since municipal roads need to be passed day and night, the long maintenance time has a great impact on everyone's passage, and the high maintenance cost makes the operation of urban roads difficult; therefore, it is very necessary to provide a non-destructive rapid repair machinery and construction process for urban road inspection wells with high repair efficiency and low maintenance cost. Summary of the invention

[0003] The purpose of the present invention is to overcome the deficiencies of the prior art and to provide a non-destructive rapid repair machine and construction process for urban road inspection wells with high repair efficiency and low maintenance cost.

[0004] The object of the present invention is achieved in this way: a non-destructive rapid repair machine for an urban road inspection well, which includes a power system and a walking system, the repair machine also includes a well cover disassembly system, a well ring disassembly system and a control system, the well cover disassembly system is composed of a well cover disassembly platform, a well cover disassembly arm, a pulling subsystem and a protection subsystem, the well cover disassembly platform is installed on a vehicle frame, the upper part of the well cover disassembly platform is connected to the well cover disassembly arm, the end of the well cover disassembly arm is provided with a protection subsystem, and a pulling subsystem is provided inside the protection subsystem; the well ring disassembly system is composed of a well ring The invention relates to a disassembly and assembly platform, a manhole ring disassembly and assembly arm, a disassembly and assembly frame, a sleeve, a sleeve cover, a bottom supporting subsystem, a supporting and protecting subsystem and a jacking subsystem. The manhole ring disassembly and assembly platform is installed on a vehicle frame, the manhole ring disassembly and assembly arm is installed on the manhole ring disassembly and assembly platform, a disassembly and assembly frame is arranged below the manhole ring disassembly and assembly arm, a sleeve cover is connected below the disassembly and assembly frame, the sleeve cover is welded to the sleeve, a bottom supporting subsystem is connected to the lower end of the sleeve, a slide groove is opened at the lower part of the sleeve, and the supporting and protecting subsystem is arranged in the slide groove through a supporting beam; the control system is composed of control elements, control software and operating switches.

[0005] The drawing subsystem is composed of a generator, a pulse rectifier, a rheostat, a pulse coil, and an electromagnet. The generator, pulse rectifier, and rheostat are arranged inside the vehicle frame. The electromagnet is installed on the manhole cover disassembly arm. The pulse coil is wound on the electromagnet. The electromagnet is in the shape of a trumpet, with a large head and a small tail. The protection subsystem is composed of a crossbeam, a vertical beam, a hydraulic cylinder, and a pressure plate. The crossbeam is arranged at the end of the manhole cover disassembly arm. The vertical beam is vertically welded to the crossbeam. A hydraulic cylinder is arranged in the middle of the crossbeam and the vertical beam. The length is adjusted by the hydraulic cylinder. The pressure plate is fixed at the lower end of the vertical beam. The electromagnet is arranged in the protection subsystem. The working principle of the drawing subsystem is: the engine drives the generator to work to generate current. The current is rectified by the pulse rectifier and passes through the pulse coil to make the electromagnet generate magnetism. The magnitude of the magnetic force can be adjusted by the rheostat. When removing the manhole cover, the electromagnet is brought into contact with the cast iron manhole cover, and the magnetic switch is turned on. The electromagnet generates magnetism and suction, and the cast iron manhole cover is pulled out of the manhole ring on the original ground under the action of the magnetic force; when installing the manhole cover, the electromagnet is first sucked to hold the cast iron manhole cover, and then the cast iron manhole cover is horizontally moved to the upper part of the manhole ring and placed in the manhole ring, and then the magnetic switch is turned off, the magnetism of the electromagnet disappears, and the electromagnet is removed. The working principle of the protection subsystem is: when removing the manhole cover, first lower the two ends of the vertical beam to the outside of the manhole ring, and adjust the length of the crossbeam through the hydraulic cylinder so that the pressure plate presses the upper edge of the manhole ring (the pressure plate cannot affect the manhole cover from being pulled out), and the manhole ring is fixed when the manhole cover is pulled out to prevent the manhole ring from moving up and tilting and protect the concrete around the manhole ring from being damaged.

[0006] The power system consists of an engine, a gearbox, a transfer case, a hydraulic motor, and a hydraulic pump. The engine power enters the transfer case after passing through the gearbox, and the transfer case drives the hydraulic motor and the hydraulic pump to provide power for the walking system, the manhole cover disassembly system, and the manhole ring disassembly system; the walking system consists of an engine, a gearbox, a transfer case, a differential, a drive axle, and tires. The engine power enters the transfer case after passing through the gearbox, and the transfer case power drives the differential and the drive axle to move.

[0007] The bottom supporting subsystem is composed of a main shaft, a circular gear, a flat gear, a casing, a supporting rod and a locking device. The upper end of the main shaft is connected to the well collar disassembly arm and passes through the disassembly frame, the sleeve cover and the support beam. The lower end of the main shaft is equipped with a circular gear through a spline. The number of the casing, the flat gear and the supporting rod are two and they are symmetrically distributed along the main shaft. The casing is fixed on the casing. The supporting rod passes through the casing and can slide horizontally along the casing. The outer end of the flat gear is connected to the supporting rod, and the inner end of the flat gear is meshed with the circular gear. The working principle of the bottom supporting subsystem is: the hydraulic pump drives the main shaft to rotate, and the main shaft drives the circular gear to rotate. Since the flat gear is meshed with the circular gear, when the circular gear rotates counterclockwise, the two flat gears move outward, and the flat gear drives the supporting rod to move outward along the casing, so that the supporting rod supports the bottom of the well collar. The rising of the supporting rod can pull the well collar out of the inspection well. When the circular gear rotates clockwise, the two flat gears move inward, and the flat gears drive the support rod to move inward along the casing, so that the support rod can be separated from the bottom of the well circle.

[0008] The locking device consists of a control disk, a tooth, a locking control pin, a locking spring, a locking sleeve, and a pull-wire switch. The control disk is installed on the main shaft through a spline. The control disk is located below the circular gear. The outer edge of the control disk is provided with a tooth. The locking sleeve is fixedly provided on the sleeve. The locking control pin and the locking spring are installed in the locking sleeve. The pull-wire switch is connected to the locking control pin and passes through the locking spring and the sleeve. The locking control pin can move left and right in the locking sleeve through the pull-wire switch. The working principle of the locking device: Release the pull-wire switch, the locking control pin engages with the tooth under the elastic force of the spring, and the locking control pin presses against the tooth, so that the control disk cannot rotate; tighten the pull-wire switch, at this time, the locking control pin is separated from the tooth, and the control disk can rotate freely.

[0009] The support and protection subsystem consists of a support beam, a semicircular protection plate, a connecting rod, a sliding hole, a spring, a wire rope, a guide wheel, a pin shaft, a pin shaft frame, a handle, a tooth plate, a tooth plate hole, teeth, a positioning pin, a positioning pin spring, a pin sleeve, a flat groove, and a pin groove. A sliding groove is opened in the lower part of the sleeve, and the support beam is located in the sliding groove and can slide up and down along the sliding groove. A vertical sliding hole is arranged on the outer side of the support beam. The upper end of the connecting rod passes through the sliding hole and can move inward and outward along the sliding hole. The lower end of the connecting rod is connected to a semicircular protection plate. The number of the semicircular protection plates is two to form a circumferential protection plate. The inner diameter of the circumferential protection plate is larger than the outer diameter of the well ring. The function of the circumferential protection plate is In order to avoid the concrete around the well ring from being damaged when the well ring is pulled out from the inspection well, the outer end of the spring is fixedly arranged on the top of the support beam, the inner end of the spring is connected to the connecting rod, the handle and the tooth plate are consolidated into an integrated structure, the handle and the tooth plate form a lever structure through a pin shaft, the pin shaft frame is installed on the sleeve, a tooth plate hole is provided on the tooth plate, one end of the steel wire rope is connected to the tooth plate hole, the other end of the steel wire rope is connected to the connecting rod, and the direction is changed through a guide wheel in the middle, the guide wheel is fixed on the support beam, the pin sleeve is fixed on the support beam, the locating pin and the locating pin spring are located in the pin sleeve, the pin sleeve is provided with a flat groove and a pin groove, the locating pin can move left and right in the flat groove of the pin sleeve and be positioned through the pin groove. Working principle of the support and protection subsystem (taking the right side as an example): When the support and protection subsystem needs to work, place the positioning pin in the pin slot, move the handle to rotate the tooth plate counterclockwise, and drive the wire rope inward through the guide wheel to change the direction of the tooth plate. The wire rope pulls the connecting rod and the semicircular protection plate inward. When the two semicircular protection plates form a circumferential protection plate, stop applying force to the handle and place the positioning pin in the flat slot. At this time, due to the engagement of the positioning pin and the tooth plate, the tooth plate is fixed, and the next step is to pull the well ring. After the well ring pulling work is completed, move the positioning pin to place the tail of the positioning pin in the pin slot. At this time, the tooth plate resumes free rotation, and the connecting rod and the semicircular protection plate move outward under the action of the spring elastic force, ending this work.
