Description

Technical Field

[0001] The invention relates to the technical field of drainage pipe construction, and in particular to an elevated bridge pavement water supply and drainage construction operation device and a construction method. Background Art

[0002] The installation of drainage pipes of viaducts is a key link in their water supply and drainage construction. First, grooves need to be dug on the surface of the viaduct and several drainage holes need to be set at the bottom of the grooves to facilitate the installation of vertical drainage pipes. The drainage holes must penetrate to the bottom of the viaduct, and then horizontal drainage pipes are installed to connect the vertical drainage pipes. The horizontal drainage pipes are exposed at the bottom of the viaduct. Through the vertical drainage pipes, rainwater on the surface is collected in the horizontal drainage pipes, thereby achieving effective drainage of the surface of the viaduct.

[0003] However, since the viaduct itself is usually a certain distance from the ground, the existing technology mostly uses a crane suspension method to install drainage pipes. Specifically, the installation process requires operators to be suspended in the air to operate, and operators are required to cooperate in transferring the drainage pipes on the bridge deck. Not only does it require a large number of operators to participate in the construction, but the operation is also more troublesome. In addition, the above-mentioned high-altitude transfer pipes also have certain risks. For example, the drainage pipes are easily collided with the installers during the suspension below, and there is always a risk of the installation workers falling when transferring the water pipes above.

[0004] In the prior art, a Chinese patent for a method for water supply and drainage construction on an elevated bridge pavement (publication number CN116497918B) is proposed to solve the above-mentioned technical problems. The technical solution disclosed in the patent document is as follows: "A pipe transport trolley is used to transport and unload pipes. Under the coordinated action of the clamping mechanism and the rotating jacking mechanism, adjacent water pipe units are connected on an inclined receiving platform. At the same time, the unloading operation can be completed by the self-gravity of the water pipe units under the forward movement of the pipe transport trolley. There is no need for construction workers to climb to a high place to install the pipes, which improves the safety of construction, simplifies the installation steps of drainage pipes, and further improves the installation efficiency of drainage pipes." However, this solution will bring some problems in actual operation:

[0005] Since tunnels for installing drainage pipes need to be excavated directly on the bridge deck, and concrete needs to be backfilled after the pipes are laid, the operation process is complicated and the operation volume is large. In addition, it is necessary to wait for the new concrete to solidify after backfilling, which makes the construction efficiency low and the construction period long. Digging ditches on the bridge deck will damage the elevated structure and affect the structural strength of the viaduct. The pipes are buried inside the road surface, which makes subsequent cleaning and maintenance operations inconvenient. The location of the pipes is difficult to withstand long-term loads. Summary of the invention

[0006] The purpose of the present invention is to provide an elevated bridge pavement water supply and drainage construction device and construction method to solve the problem that the prior art installation process requires operators to be suspended in the air to operate, and the operator needs to cooperate on the bridge deck to transfer the drainage pipe operation, which is troublesome and poses a safety hazard.

[0007] A device for water supply and drainage construction of elevated bridge pavement comprises an elevated bridge body, a self-propelled vehicle and a drainage pipe, and also comprises: a pipeline robot; a clamp fixedly mounted on the side wall of the elevated bridge body and used for installing the drainage pipe; two guide ropes are arranged in parallel, one end of the pipeline robot is fixedly connected to a traction block; a feeding component is mounted on the top of the self-propelled vehicle and used for delivering the drainage pipe to the installation position; the feeding component comprises a mounting frame fixedly connected to the top of the self-propelled vehicle, the guide rope is an elastic structure, the two ends of the guide rope are respectively fixedly connected to the traction block and the material discharge rail, both sides of the mounting frame are fixedly connected to slide rails, and the outer sides of the two slide rails are symmetrically slidable There are two slides that are dynamically connected, and fixing parts are fixedly connected between the adjacent sides of the slides. The loading component also includes a discharge rail, and four positioning plates are fixedly connected to the bottom of the discharge rail, and the discharge rail is fixed to the slide through the positioning plates; the control component is arranged on the side of the mounting frame close to the slide rail, and is used to control the slide to slide on the slide rail, and the two slides on the same slide rail slide in the center; the correction component is arranged at the bottom of the self-propelled vehicle, and is used to control the driving trajectory of the self-propelled vehicle; the docking component is arranged on the top of the self-propelled vehicle, and is used to adjust the angle of the drainage pipe delivered to the installation position, and push the drainage pipe to dock with the installed pipe.

[0008] By adopting the above technical scheme, two groups of slide plates are set to fix the discharge rail, and each group slides in a centrally-aligned manner, and the movement directions of the two groups of slide plates are relatively opposite, that is, when the slide plate located at the bottom moves to the side close to each other, the discharge rail can be fixed from the bottom, and the slide plate located at the top is at the relatively farthest distance at this time, so that the drain pipe can be placed from the top. After the drain pipe is placed, it is limited by the slide plate (and the fixing part) below and will not slide down, so that it is inserted into the outside of the discharge rail; further, the upper end of the discharge rail can be fixed by moving the slide plate located at the top to the side close to each other until the discharge rail is clamped, and correspondingly, the slide plate located at the bottom releases the discharge rail, so that the drain pipe can slide down along the guide rope to realize feeding.

[0009] A further improvement of the technical solution of the present invention is that: the control component includes an air pump fixedly mounted on one side of a mounting frame, a valve body is fixedly connected to the middle part of the mounting frame, a valve core is rotatably connected between the inner walls of the valve body, and two L-shaped valve holes are provided on the valve core; four air cylinders are fixedly connected to one side of the mounting frame close to the slide rail, piston plates are slidably connected between the inner walls of the four air cylinders, a push rod is fixedly connected to one side of the piston plate, and the ends of the four push rods away from the piston plate correspond to the four slide plates one by one and are fixedly connected, four pipe joints are equidistantly arranged around the outside of the valve body, one of the pipe joints is connected to the air pump, and an air intake pipe is fixedly connected to the pipe joints in relative positions, and every two air cylinders are connected to a pipe joint through a pipe; the diameter of the air intake pipe is smaller than the diameter of the pipe connecting the air pump and the pipe joint; a first spring is sleeved on the outside of each slide rail and between the slides.

[0010] By adopting the above technical scheme, the two slides are driven to move by utilizing air pump to draw air, and an air intake pipe with a smaller diameter is provided as an air intake channel for resetting. During the switching process of the fixed point, the valve core is controlled to rotate until the air pump is connected to the corresponding air cylinder. Under the action of the air pump, the two slides are quickly slid to the side close to each other and fix the discharge rail. On the other side, since the diameter of the air intake pipe is smaller than the pipe between the air pump and the valve body, the speed at which the gas enters the air cylinder from the air intake pipe is lower than the speed at which the air pump draws air on the other side. The discharge rail can be fixed by the fixing part on the other side before the fixing part at the fixed point releases the discharge rail, and the time difference allows the discharge rail to be fixed with less deflection to avoid jamming or inadequate fixation.

[0011] A further improvement of the technical solution of the present invention is that: a control cabinet is fixedly connected to the side of the mounting frame away from the valve body, a fixing plate is fixedly connected between the inner walls of the control cabinet, the central axis of the valve core passes through the mounting frame and the fixing plate and is fixedly connected to a rocker arm, a sliding rod is slidably connected between the two sides of the control cabinet, a connecting column is fixedly connected to the outer side of the sliding rod, a tension spring is fixedly connected between the connecting column and the end of the rocker arm away from the fixing plate, and a limiting buckle is symmetrically fixedly connected to one side of the fixing plate; an operating handle is fixedly connected between the two ends of the sliding rod.

[0012] By adopting the above technical solution, a rocker arm and a tension spring are set, and the operating handle is pushed tilted to make the slide bar move along the pushing direction, thereby driving the rocker arm to swing through the tension spring. Before the rocker arm flips over the central position of the fixed plate, it will be hindered by the elastic force of the tension spring and the pushing will be hindered, thereby avoiding switching due to misoperation. However, after the rocker arm flips over the central position of the fixed plate, the rocker arm will assist the rocker arm to move quickly under the action of the tension spring until the rocker arm contacts the limit buckle. This process will make the switching process proceed quickly.

[0013] A further improvement of the technical solution of the present invention is that the docking component includes a lifting structure fixedly connected to the top of the self-propelled vehicle, the bottom of the lifting structure is fixedly connected to a lifting platform, the lifting structure is used to control the movement of the lifting platform, the top of the lifting platform is fixedly connected to an electric telescopic rod, the movable end of the electric telescopic rod is fixedly connected to a push plate, one side of the push plate is fixedly connected to a guide frame, the inner side of the guide frame is symmetrically rotatably connected to two pulleys, a guide roller is fixedly connected between the sides of the two pulleys that are close to each other, and the guide roller is set as a roller-shaped structure with a central radius larger than the end radius.

[0014] By adopting the above technical solution, the lifting platform is lowered by controlling the operation of the lifting structure. During the process, the pulley will press the guide rope downward until the lower end of the guide rope is pressed to a horizontal state (relying on the stretchable characteristics of the guide rope). At this time, the sliding drain pipe is aligned with the installed drain pipe, and then the electric telescopic rod is controlled to drive the push plate to move toward the drain pipe, so that the inner pipe head of the unfixed drain pipe is inserted into the sleeve head.

[0015] A further improvement of the technical solution of the present invention is that: the clamp includes an L-shaped plate, one side of the L-shaped plate is fixedly connected with a plurality of U-shaped buckles, one side of the U-shaped buckle is provided with a bayonet, and the L-shaped plate is also provided with a plurality of mounting holes, and the L-shaped plate is installed on the side of the viaduct body by bolts and mounting holes; L-shaped buckles are symmetrically fixedly connected on both sides of the drainage pipe, an end of the L-shaped buckle away from the drainage pipe is provided with a movable seam, and two barbs are fixedly connected to the outer end of the L-shaped buckle close to the movable seam, and one end of the barb is set as an arc surface.

[0016] By adopting the above technical solution, when installing the drain pipe, the drain pipe is kept in a horizontal state, and the drain pipe is pushed back in the horizontal direction so that the L-shaped buckles on both sides of the drain pipe are inserted along the U-shaped buckles. Specifically, during the insertion process, the end of the L-shaped buckle with the barb is deformed toward the movable gap under the mutual squeezing action of the arc surface and the U-shaped buckle, so that the L-shaped buckle can continue to be inserted, and continue to be inserted until the barb moves to the bayonet position. At this time, the inner side of the L-shaped buckle is in contact with the U-shaped buckle, thereby realizing the rapid installation of the drain pipe and the clamp.

[0017] A further improvement of the technical solution of the present invention is that: one end of the drain pipe is fixedly connected to an inner pipe head, the end of the drain pipe away from the inner pipe head is fixedly connected to a sleeve head, a slot is provided on the inner side of the sleeve head, and a sealing strip is fixedly connected to the inside of the inner pipe head; grooves are provided around the inner pipe head, an elastic sheet is connected to the inside of the groove, and the elastic sheet is used in conjunction with the slot; a chamfer is provided at the outer end of the inner pipe head, and a chamfer is provided at the inner end of the sleeve head.

[0018] By adopting the above technical solution, the inner pipe head of the unfixed drain pipe is inserted into the sleeve head. During the process, each spring piece is squeezed and deformed, so that the drain pipe can be smoothly inserted until the spring piece is stuck in the slot and fixed; when the above-mentioned engagement is completed, the drain pipe and the corresponding clamp are clamped together, and the sealing strip is squeezed, thereby completing the subsequent installation of the drain pipe.

[0019] A further improvement of the technical solution of the present invention is that: a traction block is fixedly connected to one end of the pipeline robot, one end of the guide rope is fixedly connected to the traction block, the end of the guide rope away from the traction block is fixedly connected to the discharge rail, slide grooves are provided on both sides of the traction block, a pad is slidably connected between the inner walls of the slide groove, a second spring is fixedly connected between the pad and the inner wall of the slide groove, a clamping block is fixedly connected to the side of the pad away from the second spring, and one side of the clamping block has an inclined surface.

[0020] By adopting the above technical solution, during the insertion process of the inner pipe head, the traction block and the pipeline robot will be pushed to move, and during the movement of the traction block, the clamping block will move toward the center until it is disengaged from the clamping groove, so that the pipeline robot can be disengaged from the fixed drainage pipe when the two sections of the drainage pipe are connected. The pipeline robot moves forward under the action of the rebound force of the guide rope, and the subsequent movement of the self-propelled vehicle will cause the pipeline robot to be stuck in the fixed drainage pipe.

[0021] A further improvement of the technical solution of the present invention is that the correction component includes two side plates, both side plates are fixedly connected to one side of the bottom of the self-propelled vehicle, one side of the side plate is slidably connected to a pressure rod, one end of the pressure rod is fixedly connected to a limiting block, the end of the pressure rod away from the limiting block extends to the other side of the side plate and is rotatably connected to a roller, a third spring is sleeved on the outer side of the pressure rod, an induction plate is fixedly connected to the bottom of the self-propelled vehicle, an infrared sensor is fixedly installed on the side of the limiting block away from the pressure rod, and a counterweight block is arranged on the top of the self-propelled vehicle.

[0022] By adopting the above technical solution and setting a deviation correction component, during the normal movement of the self-propelled vehicle, the guardrail is kept to produce the same degree of squeezing on the two rollers, and the compression degree of the third spring is the same, so that the feedback of the infrared sensor is the same. The signal is analyzed and processed by the controller on the self-propelled vehicle. When the self-propelled vehicle is deflected relative to the side guardrail of the elevated bridge body, the rollers of the guardrail on one side will be more squeezed, and the corresponding limit block and infrared sensor will be pushed to produce more displacement. The distance between the two infrared sensors and the sensing sheet will be different, so it is determined that the self-propelled vehicle is deflected relative to the path, and the path is adjusted through the controller.

[0023] The present invention also provides a method for water supply and drainage construction of an elevated bridge pavement:

[0024] S1. Install clamps at equal intervals on the flanks of the viaduct body, install a drainage pipe on the clamp at the head end, prepare a self-propelled vehicle and a pipeline robot, and place the pipeline robot into the installed drainage pipe;

[0025] Specifically, the distance between the farthest ends of the two parallel guide ropes is equal to the distance between the two opposite sides of the inner wall of the drain pipe, so that the two corners of the drain pipe slide along the guide ropes during the sliding process, and no deflection occurs, so as to facilitate alignment. The guide rope is an elastic rope with retractable properties, and the tension received by the drain pipe during the sliding process is small, and the guide rope will not be stretched excessively.

[0026] S2. Control the self-propelled vehicle to travel along the extension path of the viaduct body, and control the driving trajectory of the self-propelled vehicle through the deviation correction component to prevent the self-propelled vehicle from deviating. Each driving distance is the length of a single section of the drainage pipe. After completing a single driving, the drainage pipe is placed through the loading component. The pipeline robot and the loading component are connected by two parallel guide cables. The placed drainage pipe slides along the guide cables until it contacts the previously installed drainage pipe;

[0027] Specifically, the placement and installation of the drainage pipe do not require operators to suspend the installation, thereby avoiding the situation where the pipe hits or hits the operator, and improving the safety of the construction.

[0028] S3. Adjust the lower end of the guide rope to a horizontal state through the docking component so that the drain pipe placed in step S2 is directly opposite to the installed drain pipe. Then use the docking component to push the drain pipe into the installed drain pipe until the docking is completed. The pipeline robot detaches from the pipeline and moves to the newly installed drain pipe. At the same time, the drain pipe and the clamp are self-lockingly fixed.

[0029] By pressing down the middle part of the guide rope near the lower end, the guide rope is stretched until the lower end is in a horizontal state. At this time, the drainage pipe on the guide rope will become horizontal and aligned with the installed pipe, thereby facilitating socket installation.

[0030] S4. Repeat steps S2 and S3 to sequentially lay out drainage pipes along the main body of the viaduct.

[0031] S5. Connect the laid drainage pipes to the drainage holes reserved on the main body of the viaduct through the water inlet pipes, install the outlet pipes on the main piers of the viaduct and lead them down to the ground, and connect the drainage pipes close to the piers with the outlet pipes.

[0032] Due to the adoption of the above technical solution, the present invention has the following technical advances compared with the prior art:

[0033] 1. The present invention provides an elevated bridge pavement water supply and drainage construction device and construction method, which transmits the pipeline by setting an inclined guide rope, and bends the guide rope at the center near the lower end when the pipeline is transmitted to the target position, so that the guide rope is in a horizontal state, so that the uninstalled drainage pipe is aligned with the installed drainage pipe, so that the placement and installation of the drainage pipe do not require the operator to suspend the installation, thereby avoiding the situation where the pipeline hits or hits the operator, and improving the safety of construction.

[0034] 2. The present invention provides two groups of slide plates for fixing the discharge rail, each group of slides moves in a centrally aligned manner, and the movement directions of the two groups of slide plates are relatively opposite, that is, when the slide plate located at the bottom moves toward the side close to each other, the discharge rail can be fixed from the bottom, and the slide plate located at the top is at the relatively farthest distance at this time, so that the drain pipe can be placed from the top, and after the drain pipe is placed in, it is limited by the slide plate at the bottom and will not slide down, so that it is temporarily inserted on the discharge rail; further, the upper end of the discharge rail can be fixed by moving the slide plate located at the top toward the side close to each other until the discharge rail is clamped, and correspondingly, the slide plate at the bottom releases the discharge rail, so that the drain pipe can slide down along the guide rope to realize feeding.

[0035] 3. The present invention forms a fool-proof structure by arranging a rocker arm and a tension spring. Specifically, during operation, the operating handle is pushed by tilting to make the slide bar move along the pushing direction, thereby driving the rocker arm to swing through the tension spring. Before the rocker arm turns over the central position of the fixed plate, the elastic force of the tension spring will hinder the pushing, thereby avoiding switching due to misoperation. However, after the rocker arm turns over the central position of the fixed plate, the rocker arm will assist the rocker arm to move quickly under the action of the tension spring until the rocker arm contacts the limit buckle. This process will enable the switching process to proceed quickly, thereby avoiding misoperation and achieving quick action when operation is required.

[0036] 4. The present invention provides a quick-insert clamp and a matching drain pipe. When the drain pipe is installed, the drain pipe is kept in a horizontal state, and the drain pipe is pushed back in the horizontal direction so that the L-shaped buckles on both sides of the drain pipe are inserted along the U-shaped buckles. Specifically, during the insertion process, one end of the L-shaped buckle with a barb is deformed toward the movable gap under the mutual squeezing action of the arc surface and the U-shaped buckle, so that the L-shaped buckle can continue to be inserted until the barb moves to the bayonet position. At this time, the inner side of the L-shaped buckle is in contact with the U-shaped buckle, thereby realizing the rapid installation of the drain pipe and the clamp.

[0037] 5. The present invention provides a pipeline robot that can automatically disengage after the pipeline socket is in place. During the actual installation process, the insertion of the inner pipe head will push the traction block and the pipeline robot to move, and during the movement of the traction block, the clamping block will move toward the center until it is disengaged from the clamping groove, so that the pipeline robot can be disengaged from the fixed drainage pipe when the two sections of the drainage pipe are connected. The pipeline robot moves forward under the action of the rebound force of the guide rope, and the subsequent movement of the self-propelled vehicle will cause the pipeline robot to be stuck in the fixed drainage pipe.

[0038] 6. The present invention sets a deviation correction component to maintain the same degree of squeezing of the guardrail on the two rollers and the same degree of compression of the third spring during the normal movement of the self-propelled vehicle, so that the feedback of the infrared sensor is the same. The signal is analyzed and processed by the controller on the self-propelled vehicle. When the self-propelled vehicle is tilted relative to the side guardrail of the elevated bridge body, the rollers of the guardrail on one side will be more squeezed, and the corresponding limit blocks and infrared sensors will be pushed to produce more displacement. The distance between the two infrared sensors and the sensing sheets will be different, so it is determined that the relative path of the self-propelled vehicle is deviated, and the path is adjusted through the controller.

[0060] The present invention is further described in detail below in conjunction with embodiments:

[0061] Example 1

[0062] like Figure 1 , Figure 2 and Figure 5 As shown, a water supply and drainage construction device for an elevated bridge road surface comprises an elevated bridge body 1, a self-propelled vehicle 2 and a drainage pipe 3, and also comprises: a pipeline robot 26; a clamp 4, fixedly mounted on the side wall of the elevated bridge body 1, for installing the drainage pipe 3; two guide cables 31 are arranged in parallel, one end of the pipeline robot 26 is fixedly connected to a traction block 27; a feeding component, mounted on the top of the self-propelled vehicle 2, for delivering the drainage pipe 3 to the installation position; the feeding component comprises a mounting frame 5 fixedly connected to the top of the self-propelled vehicle 2, the guide cable 31 is an elastic structure, the two ends of the guide cable 31 are respectively fixedly connected to the traction block 27 and the material discharge rail 9, both sides of the mounting frame 5 are fixedly connected to slide rails 6, and the outer sides of the two slide rails 6 are There are two slide plates 7 symmetrically slidably connected, and fixing parts 8 are fixedly connected between the adjacent sides of the slide plates 7. The loading component also includes a discharge rail 9, and four positioning plates 10 are fixedly connected to the bottom of the discharge rail 9. The discharge rail 9 is fixed with the slide plate 7 through the positioning plates 10; the control component is arranged on the side of the mounting frame 5 close to the slide rail 6, and is used to control the slide plate 7 to slide on the slide rail 6, and the two slide plates 7 located on the same slide rail 6 slide in alignment; the correction component is arranged at the bottom of the self-propelled vehicle 2, and is used to control the driving trajectory of the self-propelled vehicle 2; the docking component is arranged on the top of the self-propelled vehicle 2, and is used to adjust the angle of the drain pipe 3 delivered to the installation position, and push the drain pipe 3 to dock with the installed pipe.

[0063] In order to facilitate the delivery of the drainage pipe 3 from the viaduct body 1 to the installation position, a guide rope 31 is set as a track and gravity is used to deliver the drainage pipe 3. However, since the guide rope 31 needs to pass through the drainage pipe 3, if the upper end of the guide rope 31 is directly fixed to the installation frame 5, there will inevitably be an obstruction on the feeding track, making it impossible to complete the delivery of the drainage pipe 3.

[0064] In this embodiment, two groups of slide plates 7 are provided for fixing the discharge rail 9, and each group of slide plates 7 is centered and movable, and the movable directions of the two groups of slide plates 7 are relatively opposite, that is, when the slide plate 7 located at the bottom moves toward the side close to each other, the discharge rail 9 can be fixed from the bottom, and the slide plate 7 located at the top is at the farthest distance, so that the drain pipe 3 can be placed from the top. After the drain pipe 3 is placed, it is limited by the slide plate 7 (and the fixing member 8) at the bottom and will not slide down, so that it is temporarily inserted on the discharge rail 9;

[0065] Furthermore, the upper end of the discharge rail 9 can be fixed by moving the upper slide 7 toward the adjacent side until the discharge rail 9 is clamped. Correspondingly, the lower slide 7 releases the discharge rail 9, so that the drain pipe 3 can slide downward along the guide rope 31 to realize feeding.

[0066] like Fig.10 , Fig.12 , Fig.16 and Fig.18 As shown, preferably, the control component includes an air pump 11 fixedly mounted on one side of the mounting frame 5, a valve body 12 is fixedly connected to the middle position of one side of the mounting frame 5, a valve core 25 is rotatably connected between the inner walls of the valve body 12, and two L-shaped valve holes are provided on the valve core 25; four air cylinders 15 are fixedly connected to one side of the mounting frame 5 close to the slide rail 6, a piston plate 16 is slidably connected between the inner walls of the four air cylinders 15, a push rod 17 is fixedly connected to one side of the piston plate 16, and the four push rods 17 are away from the piston plate 16. One end corresponds to four slides 7 one by one and is fixedly connected. Four pipe joints 13 are equidistantly arranged around the outside of the valve body 12, one of which is connected to the air pump 11, and an air intake pipe 24 is fixedly connected to the pipe joint 13 at a relative position. Every two air cylinders 15 are connected to one pipe joint 13 through a pipe; the diameter of the air intake pipe 24 is smaller than the diameter of the pipe connecting the air pump 11 and the pipe joint 13; a first spring 14 is sleeved on the outside of each slide rail 6 and between the slides 7.

[0067] In order to meet the requirements of the guide rope 31 for transferring the drain pipe 3 and fixing the upper end, two fixing points are set for the discharge rail 9. By switching the two fixing points, the discharge rail 9 can be fixed to allow the drain pipe 3 to pass. However, during the switching process of the two fixing points, if the fixing and release of the discharge rail 9 are carried out simultaneously, the discharge rail 9 will be switched to another fixing point for fixing in the case of excessive loosening, which makes it difficult to align the fixing member 8 with the positioning plate 10 to complete the positioning, and the discharge rail 9 is likely to fall off during the loosening and fixing process.

[0068] In this embodiment, the two slides 7 are driven to move by means of air pumping by the air pump 11, and an air intake pipe 24 with a smaller diameter is provided as an air intake passage for resetting. During the switching process of the fixed point, the valve core 25 is controlled to rotate to connect with the air pump 11 and the corresponding air cylinder 15. Under the action of the air pump 11, the two slides 7 quickly slide to the side close to each other and fix the discharge rail 9. On the other side, since the diameter of the air intake pipe 24 is smaller than the pipeline between the air pump 11 and the valve body 12, the speed at which the gas enters the air cylinder 15 from the air intake pipe 24 is lower than the speed at which the air pump 11 on the other side draws air. The discharge rail 9 can be fixed by the fixing part 8 on the other side before the fixing part 8 at the fixed point releases the discharge rail 9, and the time difference allows the discharge rail 9 to be fixed with less deflection to avoid jamming or inadequate fixation.

[0069] like Fig. 9 , Fig.10 and Fig.18 As shown, preferably, a control cabinet 18 is fixedly connected to the side of the mounting frame 5 away from the valve body 12, a fixing plate is fixedly connected between the inner walls of the control cabinet 18, the central axis of the valve core 25 passes through the mounting frame 5 and the fixing plate and is fixedly connected to a rocker arm 19, a slide rod 20 is slidably connected between the two sides of the control cabinet 18, a connecting column 21 is fixedly connected to the outer side of the slide rod 20, a tension spring 22 is fixedly connected between the connecting column 21 and the end of the rocker arm 19 away from the fixing plate, and a limit buckle is symmetrically fixedly connected to one side of the fixing plate; an operating handle 23 is fixedly connected between the two ends of the slide rod 20.

[0070] In the process of placing the drain pipe 3 using the discharge rail 9, the switch can be quickly performed when there is a switching demand, and there should be resistance to hinder the switching when there is no switching demand, so as to avoid misoperation or incorrect switching of the fixed point due to vibration and other reasons;

[0071] In this embodiment, by providing a rocker arm 19 and a tension spring 22, the operating handle 23 is pushed tilted to make the slide bar 20 move along the pushing direction, thereby driving the rocker arm 19 to swing through the tension spring 22. Before the rocker arm 19 flips over the central position of the fixed plate, it will be hindered from being pushed by the elastic force of the tension spring 22, thereby avoiding switching due to misoperation. However, after the rocker arm 19 flips over the central position of the fixed plate, the tension spring 22 will assist the rocker arm 19 to move quickly until the rocker arm 19 contacts the limit buckle. This process will enable the switching process to proceed quickly.

[0072] Example 2

[0073] like Figure 2 , Figure 5 and Fig.15 As shown, on the basis of Example 1, the present invention provides a technical solution: preferably, the docking component includes a lifting structure 50 fixedly connected to the top of the self-propelled vehicle 2, the bottom of the lifting structure 50 is fixedly connected to a lifting platform 51, the lifting structure 50 is used to control the movement of the lifting platform 51, the top of the lifting platform 51 is fixedly connected to an electric telescopic rod 52, the movable end of the electric telescopic rod 52 is fixedly connected to a push plate 53, one side of the push plate 53 is fixedly connected to a guide frame 54, the inner side of the guide frame 54 is symmetrically rotatably connected to two pulleys 55, a guide roller 56 is fixedly connected between the two pulleys 55 on the adjacent sides, and the guide roller 56 is set as a roller-shaped structure with a central radius larger than the end radius.

[0074] In this embodiment, the lifting platform 51 is lowered by controlling the operation of the lifting structure 50. During this process, the pulley 55 presses the guide rope 31 downward until the lower end of the guide rope 31 is pressed to a horizontal state (due to the stretchable characteristics of the guide rope 31). At this time, the sliding drain pipe 3 is aligned with the installed drain pipe 3, and then the electric telescopic rod 52 is controlled to work to drive the push plate 53 to move toward the drain pipe 3, so that the inner pipe head 33 of the unfixed drain pipe 3 is inserted into the sleeve head 32.

[0075] Among them, the hoisting structure 50 can control the lifting platform 51 to rise and fall in the vertical direction when working, and when not in use, the lifting platform 51 can be moved closer to the self-propelled vehicle 2 when it is higher than the side guardrail of the viaduct body 1, so as to facilitate transportation.

[0076] Example 3

[0077] like Figure 8 , Fig.11 and Fig.14 As shown, on the basis of Example 2, the present invention provides a technical solution: preferably, the clamp 4 includes an L-shaped plate 40, one side of the L-shaped plate 40 is fixedly connected with a plurality of U-shaped buckles 41, one side of the U-shaped buckle 41 is provided with a bayonet 42, and the L-shaped plate 40 is also provided with a plurality of mounting holes, and the L-shaped plate 40 is mounted on the side of the viaduct body 1 by bolts and mounting holes; L-shaped buckles 37 are symmetrically fixedly connected on both sides of the drain pipe 3, and a movable seam 38 is provided at one end of the L-shaped buckle 37 away from the drain pipe 3, and two barbs 39 are fixedly connected to the outer end of the L-shaped buckle 37 close to the movable seam 38, and one end of the barb 39 is set as an arc surface.

[0078] In this embodiment, when the drain pipe 3 is installed, the drain pipe 3 is kept in a horizontal state, and the drain pipe 3 is pushed back in the horizontal direction so that the L-shaped buckles 37 located on both sides of the drain pipe 3 are inserted along the U-shaped buckle 41. Specifically, during the insertion process, the end of the L-shaped buckle 37 with the barb 39 is deformed toward the movable seam 38 under the mutual squeezing action of the arc surface and the U-shaped buckle 41, so that the L-shaped buckle 37 can continue to be inserted, and continue to be inserted until the barb 39 moves to the position of the bayonet 42. At this time, the inner side of the L-shaped buckle 37 is in contact with the U-shaped buckle 41, so that the drain pipe 3 and the clamp 4 can be quickly installed.

[0079] Example 4

[0080] like Figure 8 and Fig.14As shown, on the basis of Example 3, the present invention provides a technical solution: preferably, one end of the drain pipe 3 is fixedly connected with an inner pipe head 33, and the end of the drain pipe 3 away from the inner pipe head 33 is fixedly connected with a sleeve head 32, a groove 57 is provided on the inner side of the sleeve head 32, and a sealing strip 36 is fixedly connected to the inside of the inner pipe head 33; grooves 34 are provided around the inner pipe head 33, and an elastic sheet 35 is connected to the inside of the groove 34, and the elastic sheet 35 is used in conjunction with the groove 57; the outer end of the inner pipe head 33 is provided with a chamfer, and the inner end of the sleeve head 32 is provided with a chamfer.

[0081] In this embodiment, when the inner pipe head 33 of the unfixed drain pipe 3 is inserted into the sleeve head 32, each spring piece is squeezed and deformed during the process, so that the drain pipe 3 can be smoothly inserted until the spring piece is snapped into the slot 57 to complete the fixation; when the above-mentioned snapping is completed, the drain pipe 3 and the corresponding clamp 4 are snapped together, and the sealing strip 36 is squeezed, thereby completing the subsequent installation of the drain pipe 3.

[0082] Preferably, the elastic sheet 35 is bonded to the inner wall of the groove 34 by a high-temperature hot-melt adhesive. When disassembly is required, the connection between the drain pipes 3 can be detached by melting the high-temperature hot-melt adhesive at high temperature.

[0083] like Figure 8 and Fig.13 As shown, preferably, one end of the pipeline robot 26 is fixedly connected to a traction block 27, one end of a guide rope 31 is fixedly connected to the traction block 27, the end of the guide rope 31 away from the traction block 27 is fixedly connected to the discharge rail 9, and slide grooves 28 are provided on both sides of the traction block 27, and a pad is slidably connected between the inner walls of the slide groove 28, a second spring 30 is fixedly connected between the pad and the inner wall of the slide groove 28, and a clamping block 29 is fixedly connected to the side of the pad away from the second spring 30, and one side of the clamping block 29 has an inclined surface.

[0084] In this embodiment, during the insertion process of the inner pipe head 33, the traction block 27 and the pipeline robot 26 are pushed to move, and during the movement of the traction block 27, the clamping block 29 is moved toward the center until it is disengaged from the clamping groove 57, so that the pipeline robot 26 can be disengaged from the fixed drainage pipe 3 when the two sections of the drainage pipe 3 are connected. The pipeline robot 26 moves forward under the rebound force of the guide rope 31, and the subsequent movement of the self-propelled vehicle 2 will cause the pipeline robot 26 to be clamped into the fixed drainage pipe 3.

[0085] like Figure 4 and Figure 7As shown, preferably, the correction component includes two side plates 43, both of which are fixedly connected to one side of the bottom of the self-propelled vehicle 2, one side of the side plate 43 is slidably connected to a pressure rod 44, one end of the pressure rod 44 is fixedly connected to a limiting block, one end of the pressure rod 44 away from the limiting block extends to the other side of the side plate 43 and is rotatably connected to a roller 45, a third spring 48 is sleeved on the outer side of the pressure rod 44, an induction plate 46 is fixedly connected to the bottom of the self-propelled vehicle 2, an infrared sensor 47 is fixedly installed on the side of the limiting block away from the pressure rod 44, a counterweight block 49 is arranged on the top of the self-propelled vehicle 2, and the pressure rod 44 is a square rod.

[0086] In order to ensure that the downwardly descending drainage pipe 3 can face the installed drainage pipe as much as possible and avoid the device from colliding with the side guardrail of the viaduct body 1, the self-propelled vehicle 2 should be kept as parallel as possible to both sides of the viaduct body 1;

[0087] In this embodiment, by setting a correction component, during the normal movement of the self-propelled vehicle 2, the guardrail is kept to produce the same degree of squeezing on the two rollers 45, and the compression degree of the third spring 48 is the same, so that the feedback of the infrared sensor 47 is the same. The signal is analyzed and processed by the controller on the self-propelled vehicle 2. When the self-propelled vehicle 2 is deflected relative to the side guardrail of the elevated bridge body 1, the roller 45 of the guardrail on one side will be more squeezed, and the corresponding limit block and infrared sensor 47 will be pushed to produce more displacement. The distance between the two infrared sensors 47 and the sensing sheet 46 is different, so it is determined that the self-propelled vehicle 2 is deflected relative to the path, and the path is adjusted through the controller.

[0088] The present invention also provides a method for water supply and drainage construction of an elevated bridge pavement, comprising the following steps:

[0089] S1. Install clamps 4 at equal distances on the flanks of the viaduct body 1, install the drainage pipe 3 on the clamps 4 at the head end, prepare the self-propelled vehicle 2 and the pipeline robot 26, and place the pipeline robot 26 into the installed drainage pipe 3;

[0090] Specifically, the distance between the farthest ends of the two parallel guide ropes 31 is equal to the distance between the two opposite sides of the inner wall of the drain pipe 3, so that the two corners of the drain pipe 3 slide along the guide ropes 31 during the sliding process, and will not deflect, so as to facilitate alignment. The guide rope 31 is a retractable elastic rope, and the tension received by the drain pipe 3 during the sliding process is small, and the guide rope 31 will not be stretched too much.

[0091] S2, control the self-propelled vehicle 2 to travel along the extension path of the viaduct body 1, and control the driving trajectory of the self-propelled vehicle 2 through the deviation correction component to prevent the self-propelled vehicle 2 from deviating. Each driving distance is the length of a single section of the drainage pipe 3. After completing a single driving, the drainage pipe 3 is placed through the loading component. The pipeline robot 26 is connected to the loading component through two parallel guide ropes 31. The placed drainage pipe 3 slides along the guide rope 31 until it contacts the drainage pipe 3 installed in the previous section;

[0092] Specifically, the placement and installation of the drainage pipe 3 do not require the operator to suspend the installation, thereby avoiding the situation where the pipe hits or hits the operator, and improving the safety of the construction.

[0093] S3, adjust the lower end of the guide rope 31 to a horizontal state through the docking component, so that the drain pipe 3 placed in step S2 is directly opposite to the installed drain pipe 3, and then use the docking component to push the drain pipe 3 into the installed drain pipe 3 until the docking is completed, and the pipeline robot 26 is separated from the pipeline and moves to the newly installed drain pipe 3, and at the same time, the drain pipe 3 and the clamp 4 are self-lockingly fixed;

[0094] By pressing down the middle part of the guide rope 31 near the lower end, the guide rope 31 is stretched until the lower end is in a horizontal state. At this time, the drainage pipe 3 on the guide rope 31 will become horizontal and align with the installed pipe, thereby facilitating socket installation.

[0095] S4, repeating steps S2 and S3, and laying out drainage pipes 3 in sequence along the viaduct body 1.

[0096] S5. Connect the laid drainage pipe 3 to the drainage hole reserved on the viaduct body 1 through the water inlet pipe, install the outlet pipe on the pier of the viaduct body 1 and lead it down to the ground, and connect the drainage pipe 3 close to the pier with the outlet pipe.

[0097] The working principle of the elevated bridge pavement water supply and drainage construction operation device and construction method is described in detail below.

[0098] like Figure 1-Figure 19As shown, clamps 4 are installed equidistantly on the flanks of the viaduct body 1, and the self-propelled vehicle 2, the pipeline robot 26 and the drainage pipe 3 to be installed are prepared; the mounting frame 5 is configured as an extendable and foldable structure, including a screw and a telescopic rod, and when in use, the movable part can be pushed out toward the flank of the self-propelled vehicle 2 by twisting the screw until it extends out of the viaduct; the drainage pipe 3 is installed on the clamp 4 located at the head end position, the drainage pipe 3 is a square pipe and is specially designed with the clamp 4, the travel direction of the self-propelled vehicle 2 is defined as the front, the side of the drainage pipe 3 with the sleeve head 32 faces forward, and the drainage pipe 3 has an inner insert pipe One side of the head 33 faces backwards. During installation, the drain pipe 3 is kept in a horizontal state, and the drain pipe 3 is pushed back in the horizontal direction so that the L-shaped buckles 37 located on both sides of the drain pipe 3 are inserted along the U-shaped buckle 41. Specifically, during the insertion process, one end of the L-shaped buckle 37 with the barb 39 is deformed toward the movable seam 38 under the mutual squeezing action of the arc surface and the U-shaped buckle 41, so that the L-shaped buckle 37 can continue to be inserted, and the insertion is continued until the barb 39 moves to the position of the bayonet 42. At this time, the inner side of the L-shaped buckle 37 is in contact with the U-shaped buckle 41, and the installation of the first drain pipe 3 is completed at this time;

[0099] Put the pipeline robot 26 into the first installed drain pipe 3: the pipeline robot 26 has two sets of running wheels, each set has four wheels, and the running wheels are installed with the frame of the pipeline robot 26 through a retractable elastic structure. The four running wheels of each set roll along the four inner corners of the drain pipe 3, and the two opposite surfaces of the traction block 27 in the horizontal direction are in contact with the inside of the drain pipe 3. When it is put in, the inclined surfaces on one side of the clamping blocks 29 on both sides and the sleeve head 32 squeeze each other, so that the clamping block 29 squeezes the second spring 30 and automatically retracts into the inside of the slide groove 28, so that the traction block 27 can be smoothly put into the drain pipe 3 until the clamping block 29 is opposite to the clamping groove 57. At this time, the clamping block 29 pops out into the clamping groove 57 under the elastic force of the second spring 30, and the insertion stops. When the operator hears the collision sound between the clamping block 29 and the clamping groove 57, it means that the clamping is in place. At this time, the traction block 27 cannot be pulled forward by the guide rope 31 to make the pipeline robot 26 walk, and the placement of the pipeline robot 26 is completed;

[0100] The self-propelled vehicle 2 is controlled to travel along the extension path of the viaduct body 1, and each travel distance is the length of a single section of the drainage pipe 3. The self-propelled vehicle 2 is controlled to travel until the guide cable 31 is in an inclined and straightened state but not stretched. After completing a single travel, the drainage pipe 3 is put into the feeder component: before the mounting frame 5 is extended and unfolded, the slide bar 20 is moved by operating the handle 23 (a strip groove is provided on the slide bar 20 to limit it to sliding in the axial direction), so that the swing rod 19 is driven to swing through the tension spring 22, and the valve core 25 is driven to rotate until one end of the valve hole is directly opposite to the pipe joint 13 located below, as shown in FIG. Fig.10 and Fig.12d shown, at this time, the other end of the L-shaped valve hole is connected to the air pump 11 through c, and the air pump 11 is controlled to work to draw a vacuum, so that negative pressure can be obtained inside the air cylinder 15 connected to d, so that the corresponding piston plate 16 moves to the side away from the push rod 17, and drives the corresponding two slide plates 7 to move to the side close to each other, until the fixing member 8 and the positioning plate 10 are squeezed. The fixing member 8 is T-shaped, and the positioning plate 10 has a slot. When squeezed, the fixing member 8 can be inserted into the slot to fix the discharge rail 9. In this state, correspondingly, a and b are connected through another valve hole, so that the two air cylinders 15 located above are connected to the external environment through the air inlet pipe 24. At this time, since the upper piston plate 16 does not have the internal air pressure restriction of the air cylinder 15, the corresponding slide plate 7 will be pushed to the relatively farthest distance under the elastic force of the first spring 14; refer to Figure 2 , insert the drain pipe 3 to be installed on the discharge rail 9 with the side with the inner pipe head 33 facing downward, so that the discharge rail 9 passes through the drain pipe 3. At this time, the drain pipe 3 will not fall downward under the limit of the fixing member 8 below;

[0101] The unloading rail 9 and the mounting frame 5 are tied together by a tether to ensure that they will not fall. Before the air pump 11 supplies air, the unloading rail 9 is not fixed by the fixing member 8, so the operator needs to manually assist in fixing it;

[0102] After placement is completed, the operating handle 23 is pushed upward by tilting to make the slide bar 20 move in the pushing direction, thereby driving the swing rod 19 to swing through the tension spring 22. Before the swing rod 19 turns over the central position of the fixed plate, it will be hindered from being pushed by the elastic force of the tension spring 22. However, after the swing rod 19 turns over the central position of the fixed plate, the swing rod 19 will assist the swing rod 19 to move quickly under the action of the tension spring 22 until the swing rod 19 contacts the limit buckle. At this time, the swing rod 19 swings 90°, and correspondingly, the valve core 25 rotates 90°, so that the air pump 11 is connected to b through c. In this state, the air pump 11 will The two air cylinders 15 at the top are evacuated, and drive the two slide plates 7 to quickly move toward the central position until they clamp the discharge rail 9; at the same time, the valve core 25 rotates to connect a with d, and the two air cylinders 15 at the bottom are connected to the external environment through the air inlet pipe 24. The diameter of the air inlet pipe 24 is smaller than the pipe between c and the air pump 11, so the speed of gas entering is lower than the speed of air extraction by the air pump 11 on the other side, and the discharge rail 9 can be fixed by the upper fixing piece 8 before the lower fixing piece 8 releases the discharge rail 9. The subsequent switching process is to complete the fixing of the discharge rail 9 on the other side before releasing the fixing of the discharge rail 9;

[0103] Reference Figure 3 After the above operation is completed, the fixing member 8 below loses the fixation to the discharge rail 9, and at the same time, the bottom of the drain pipe 3 is lost, and the drain pipe 3 slides along the guide rope 31 until it contacts the installed drain pipe 3; refer to Figure 4, by controlling the work of the hoisting structure 50, the lifting platform 51 is lowered, and the pulley 55 presses the guide rope 31 downwards until the lower end of the guide rope 31 is pressed to a horizontal state (relying on the stretchable characteristics of the guide rope 31). At this time, the sliding drain pipe 3 is aligned with the installed drain pipe 3, and then the electric telescopic rod 52 is controlled to work to drive the push plate 53 to move in the direction of the drain pipe 3, so that the inner pipe head 33 of the unfixed drain pipe 3 is inserted into the sleeve head 32. During the process, each spring piece is squeezed and deformed, so that the drain pipe 3 can be smoothly inserted until the spring piece is stuck in the slot 57 to complete the fixation; when the above-mentioned engagement is completed, the drain pipe 3 is clamped with the corresponding clamp 4, and the sealing strip 36 is squeezed, so that the subsequent installation of the drain pipe 3 is completed;

[0104] During the insertion of the inner pipe head 33, the traction block 27 and the pipeline robot 26 will be pushed to move, and the clamping block 29 will move toward the center during the movement of the traction block 27 until it is disengaged from the clamping groove 57, so that the pipeline robot 26 can be disengaged from the fixed drainage pipe 3 when the two sections of the drainage pipe 3 are connected. The pipeline robot 26 moves forward under the rebound force of the guide rope 31, and the subsequent movement of the self-propelled vehicle 2 will cause the pipeline robot 26 to be stuck in the fixed drainage pipe 3; repeat the operation to complete the installation of the horizontal drainage pipe 3, wherein the drainage pipe 3 includes multiple models with upper pipe openings, lower pipe openings or straight pipes. The drainage pipe 3 is laid out in sequence along the viaduct body 1; the laid drainage pipe 3 is connected to the drainage hole reserved on the viaduct through a pipeline, and the water pipe is led out to the ground under the drainage pipe 3 near the pier of the viaduct body 1.

[0105] The above generally describes the present invention in detail, but it is obvious to a person skilled in the art that some modifications or improvements can be made to the present invention. Therefore, modifications or improvements that do not depart from the spirit of the present invention are within the scope of protection of the present invention.
