Description

Technical Field

[0001] This invention relates to the field of bridge precast formwork maintenance, specifically to a multi-functional operating device suitable for variable cross-section highway T-beam formwork. Background Technology

[0002] Currently, under the national strategy of new urbanization, the upgrading of urban transportation infrastructure in my country is continuously advancing. To minimize the impact of bridge construction on the surrounding environment and traffic flow, urban bridge construction is developing towards fully prefabricated assembly structures and rapid construction technologies, incorporating advanced intelligent sensing and digital technologies. The production of fully prefabricated bridge components adopts a factory assembly line operation mode, using templates of the components to be prefabricated in the precast beam yard for mass production. Taking the commonly used T-beam component for highways as an example, after the T-beam is prefabricated, its template often has residual concrete and other debris, which needs to be ground and cleaned before the next T-beam can be produced. At present, grinding and cleaning are mainly done manually, but since the surface area of ​​the template is approximately 200m²... 2 The workload is huge.

[0003] To better ensure lateral stiffness and enhance bending resistance at both ends, the horseshoe-shaped section of highway T-beams is typically designed with narrower ribs in the middle and wider at the top and bottom, resulting in a non-uniform cross-section for the highway T-beam formwork. Existing technology cannot accommodate the grinding operations on the inner walls of highway T-beam formwork with variable cross-sections. Furthermore, T-beam ribs generally have several transverse diaphragms, creating partitions in the formwork at corresponding locations. Existing grinding rollers may become stuck in these partitions during the grinding process. Summary of the Invention

[0013] In one embodiment, the wire rope assembly includes a first steering wheel longitudinally disposed above the counterweight, a second steering wheel disposed on one side of the first steering wheel and parallel to the first steering wheel, a third steering wheel longitudinally disposed outside the first grinding roller, and a first wire rope, wherein the wheel surfaces of the first steering wheel, the second steering wheel, and the third steering wheel all face the first grinding roller.

[0014] In one embodiment, one end of the first wire rope is connected to the first outer end of the top straight plate, and the other end passes sequentially around the top of the third steering wheel, the top of the first steering wheel, the counterweight, and the top of the second steering wheel, and extends toward the bottom arc plate.

[0015] In one embodiment, the bottom arc plate includes an inner side facing the first grinding roller, and the wire rope assembly further includes a fourth steering wheel, which is longitudinally disposed on the inner side of the bottom arc plate, with the wheel surface of the fourth steering wheel facing the second inner end of the bottom arc plate.

[0019] By setting up electromagnetic devices and counterweights, the extension position of the upper sidewall grinding component can be flexibly controlled according to the movement path of the equipment truss within the T-beam formwork to adapt to changes in the cross-section of the highway T-beam formwork. This also prevents the upper sidewall grinding component from sinking into the T-beam formwork partition during grinding. By setting up a widened lower sidewall grinding component, the width of the inner sidewall of the T-beam formwork can be adapted to changes in the width of the inner sidewall, allowing for grinding work on the widened area at the bottom of the inner sidewall. The top and bottom grinding units can grind the top and bottom surfaces of the T-beam formwork and can rise and move away from the grinding area after grinding, facilitating subsequent maintenance work on the T-beam formwork.

Detailed Implementation

[0030] To enable those skilled in the art to better understand the present application, the technical solutions in the embodiments of the present application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present application, and not all embodiments. Based on the embodiments in the present application, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the scope of protection of the present application.

[0031] This application provides a multi-functional operating device suitable for variable cross-section highway T-beam formwork, which can solve the technical problem in the prior art that the cross-sectional shape of the T-beam formwork is not uniform, which makes the existing grinding equipment unable to adapt well and easy to get stuck in the partition of the T-beam formwork.

[0032] This application provides a multi-functional operating device suitable for formwork of variable cross-section highway T-beams. Figure 1 This is a front view of a multi-functional operating device for variable cross-section highway T-beam formwork according to this application. The multi-functional operating device for variable cross-section highway T-beam formwork according to this application includes an equipment truss 1. The equipment truss 1 is provided with a top and bottom grinding unit 9 that can be displaced along the longitudinal direction of the equipment truss 1, and side wall grinding units provided on both sides of the equipment truss 1. The side wall grinding unit includes an upper side wall grinding component 2 that extends or retracts with an arc motion trajectory, a widened lower side wall grinding component 201 located at the bottom of the upper side wall grinding component 2, and a traction unit 3 for controlling its own longitudinal displacement to adjust the moving position of the upper side wall grinding component 2 according to the walking process of the equipment truss 1 in the T-beam formwork 10.

[0033] In order to achieve full coverage of surface grinding of T-beam template 10, the equipment truss 1 also adopts a T-shaped cross-section structure along the longitudinal direction of T-beam template 10. During the grinding operation, the multi-functional operating equipment of T-beam template in this application travels back and forth inside T-beam template 10.

[0034] The sidewall grinding units are located on both sides of the equipment truss 1 and contact the two inner sidewalls of the T-beam template 10. The two upper sidewall grinding components 2 are movable, allowing them to move towards or away from the inner sidewalls of the equipment truss 1 in an arc-shaped trajectory. Simultaneously, the upper sidewall grinding components 2 cooperate with the traction unit 3 to stop the outward expansion movement when the equipment truss 1 reaches the partition of the T-beam template 10, preventing the upper sidewall grinding components 2 from getting stuck inside the partition. The lower sidewall grinding component 201 is fixed in position, only performing rotational grinding motion in place. The lower sidewall grinding component 201 is separate from the upper sidewall grinding components 2, and its width is greater than that of the upper sidewall grinding component 2, allowing it to accommodate the widened area at the bottom of the T-beam template 10. The lower sidewall grinding component 201 adopts a grinding roller form commonly used in the prior art, including a grinding motor, grinding roller, and other components, which will not be described in detail here.

[0035] Figure 2 This is a schematic diagram of the upper sidewall grinding component 2 in a multi-functional operating device for variable cross-section highway T-beam formwork according to this application. The upper sidewall grinding component 2 includes a first grinding kit 4 arranged longitudinally. The traction unit 3 includes a counterweight block 301 that can be longitudinally displaced and an electromagnetic device 302 that cooperates with the counterweight block 301. A wire rope assembly 5 is provided between the first grinding kit 4 and the counterweight block 301 to convert the longitudinal displacement traction force of the counterweight block 301 into a motion that drives the first grinding kit 4 to perform arc motion.

[0036] The traction unit 3 is mainly used to provide displacement power for the first grinding kit 4. In this application, the counterweight 301 in the traction unit 3 is connected to the first grinding kit 4 by a wire rope assembly 5. When the equipment truss 1 has not moved to the partition of the T-beam template 10, the electromagnetic device 302 is de-energized, and the counterweight 301 falls naturally. The wire rope assembly 5 converts the vertical gravity of the counterweight 301 when it falls into the horizontal traction force, so as to drive the first grinding kit 4 to expand outward towards the inner wall of the equipment truss 1, so that the first grinding kit 4 fits tightly against the inner wall of the T-beam template 10 to ensure the grinding effect. When the equipment truss 1 moves to the partition of the T-beam template 10, the electromagnetic device 302 is energized and attracts the counterweight 301. The first grinding kit 4 stays in the current position to prevent it from falling into the partition of the T-beam template 10. The electromagnetic device 302 can be installed on the body of the first grinding kit 4 or on the equipment truss 1. There is no specific limitation in this application. However, the adsorption range of the electromagnetic device 302 must cover the displacement distance of the counterweight 301 to ensure that the counterweight 301 can be adsorbed at any time.

[0037] The energization state of the electromagnetic device 302 is determined according to the travel distance of the equipment truss 1. That is, the closed-loop frequency of the electromagnetic device 302 being energized and de-energized is preset according to the distance between two adjacent partitions of the T-beam template 10 and the travel speed of the equipment truss 1. As an optional embodiment, a distance measuring sensor can also be set on the first grinding kit 4. When the equipment truss 1 travels to the partition of the T-beam template 10, the distance between the inner wall of the T-beam template 10 and the first grinding kit 4 increases, the electromagnetic device 302 is energized, the counterweight 301 stops descending, and the first grinding kit 4 remains in place. When the equipment truss 1 leaves the partition of the T-beam template 10, the distance between the inner wall of the T-beam template 10 and the first grinding kit 4 shortens, the electromagnetic device 302 is de-energized, and the first grinding kit 4 is in close contact with the inner wall of the T-beam template 10.

[0038] The top and bottom grinding unit 9 is used to grind the bottom of the T-beam template 10 and the upper surface of the top widening section. The top and bottom grinding unit 9 can move longitudinally so that after grinding, it can be removed from the bottom and top widening section of the T-beam template 10 to facilitate subsequent cleaning and maintenance operations.

[0039] Further details can be found here. Figure 1 The equipment truss 1 is equipped with a walking drive unit 6 located at the bottom of the equipment truss 1, a dust collection unit 7 located above the walking drive unit 6, and a spraying unit 8 located at the top of the equipment truss 1.

[0040] The walking drive unit 6 is mainly used to provide power for the movement of the equipment truss 1 within the T-beam template 10. It generally includes components such as a walking motor, track wheels, and a track sweeper. The dust collection unit 7 is mainly used to absorb the dust generated during the grinding process. It generally includes components such as a dust collection host and a nylon hose. The spraying unit 8 is mainly used to perform atomized spraying on the surface of the T-beam template 10. After the grinding operation is completed, the top and bottom grinding units 9 move upward and detach from the bottom and top widening part of the T-beam template 10. The spraying unit 8 then begins spraying. The spraying unit 8 generally includes components such as a spraying host, a spraying pipe, and nozzles. The walking drive unit 6, the dust collection unit 7, and the spraying unit 8 are all commonly used structures in the prior art and will not be described in detail here.

[0041] Furthermore, Figure 3 This is a schematic diagram of the top and bottom grinding unit 9 in a multi-functional operating device for variable cross-section highway T-beam formwork in this application. The top and bottom grinding unit 9 includes a lifting gantry 901 that is consistent with the outline of the equipment truss 1. The lifting gantry 901 includes a horizontal gantry 9011 and a vertical gantry 9012 located in the middle of the horizontal gantry 9011. The bottom of both sides of the horizontal gantry 9011 is provided with a second grinding kit 902 in the horizontal direction, and the bottom of the vertical gantry 9012 is provided with a third grinding kit 903 in the horizontal direction.

[0042] The lifting gantry 901 is also T-shaped and is set on the front of the equipment truss 1 to coincide with the equipment truss 1, and moves together within the T-beam template 10. It should be noted that the front of the equipment truss 1 refers to the outer surface of the T-shaped side of the equipment truss 1. The horizontal gantry 9011 in the lifting gantry 901 is located above the widened part at the top of the T-beam template 10. The lifting gantry 901 and the equipment truss 1 are longitudinally arranged with guide units between them. The guide units include, but are not limited to, the interaction between guide rails and sliders. The sliding lifting function is a commonly used technology, and will not be described in detail here.

[0043] Two second grinding kits 902 are symmetrically arranged laterally on both sides of the bottom of the horizontal gantry 9011, that is, horizontally and perpendicularly to the traveling direction of the equipment truss 1. During the grinding process, the second grinding kits 902 are always in contact with the upper surface of the widened part of the T-beam template 10 and perform grinding work on it. The third grinding kit 903 is also arranged laterally, horizontally and perpendicularly to the traveling direction of the equipment truss 1. During the grinding process, the third grinding kit 903 is always in contact with the bottom of the T-beam template 10 and performs grinding work on it. Both the second grinding kits 902 and the third grinding kit 903 adopt the grinding roller form commonly used in the prior art, including grinding motors, grinding rollers, housings, and other components, which will not be described in detail here.

[0044] Furthermore, Figure 4 This is a detailed view of the top structure of the first grinding kit 4 in a multi-functional operating device for variable cross-section highway T-beam formwork, as described in this application. Figure 5 This is a detailed view of the bottom structure of the first grinding kit 4 in a multi-functional operating device for variable cross-section highway T-beam formwork according to this application. The first grinding kit 4 includes a first grinding roller 401, a grinding roller shell 402 located inside the first grinding roller 401, a top straight plate 403 horizontally arranged on the top of the first grinding roller 401, and a bottom arc plate 404 horizontally arranged at the bottom of the first grinding roller 401.

[0045] In this technical field, grinding rollers and grinding roller shells are often used together. The grinding roller shell is usually located on the side away from the object to be ground in order to block the dust brought out by the grinding roller during grinding. The inner side of the first grinding roller 401 in this application also refers to the side of the first grinding roller 401 away from the inner wall of the T-beam template 10. The top straight plate 403 and the bottom arc plate 404 are fixedly connected to the top and bottom of the first grinding roller 401 respectively, and drive the first grinding roller 401 to perform arc-shaped movement by its own horizontal rotation.

[0046] Figure 6 This is a detailed structural diagram of the top straight plate 403 in a multifunctional operating device for variable cross-section highway T-beam formwork according to this application. The top straight plate 403 includes a first outer end 4031 and a first inner end 4032. The first inner end 4032 is rotatably connected to the equipment truss 1. The first outer end 4031 extends horizontally away from the equipment truss 1 and is fixedly connected to the top of the first grinding roller 401. A rotating shaft is provided at the connection between the first inner end 4032 of the top straight plate 403 and the equipment truss 1, so that the first outer end 4031 of the top straight plate 403 and the first grinding roller 401 move in an arc along the rotating shaft.

[0047] Figure 7This is a detailed structural diagram of the bottom arc plate 404 in a multifunctional operating device for variable cross-section highway T-beam formwork in this application. The bottom arc plate 404 includes a second outer end 4041 and a second inner end 4042. The second outer end 4041 is fixedly connected to the bottom of the first grinding roller 401. The bottom of the lower side wall grinding assembly 201 passes through the bend of the bottom arc plate 404.

[0048] like Figure 7 As shown, the bottom arc plate 404 is L-shaped. The bottom of the grinding roller in the lower side wall grinding assembly 201 passes through the middle bend of the bottom arc plate 404, so that the bottom arc plate 404 can rotate horizontally with the grinding roller in the lower side wall grinding assembly 201 as the center. The second outer end 4041 of the bottom arc plate 404 is fixedly connected to the bottom of the first grinding roller 401. When the bottom arc plate 404 rotates along the grinding roller in the lower side wall grinding assembly 201, the first grinding roller 401 also moves accordingly.

[0049] In this application, the counterweight 301 provides a power source for the movement of the top straight plate 403 and the bottom curved plate 404, while the wire rope assembly 5 provides steering and connection functions.

[0050] The following is a breakdown of the power process by which the wire rope assembly 5 drives the top straight plate 403 to expand outward:

[0051] See Figure 4 , Figure 6 Specifically, the wire rope assembly 5 includes a first steering wheel 501 longitudinally arranged above the counterweight 301, a second steering wheel 502 arranged on one side of the first steering wheel 501 and parallel to the first steering wheel 501, a third steering wheel 503 longitudinally arranged outside the first grinding roller 401, and a first wire rope 504. The wheel surfaces of the first steering wheel 501, the second steering wheel 502, and the third steering wheel 503 all face the first grinding roller 401.

[0052] The first steering wheel 501 is fixedly mounted on the equipment truss 1 and located directly above the counterweight block 301. The second steering wheel 502 is positioned in the same manner as the first steering wheel 501, and the second steering wheel 502 is located on the side of the first steering wheel 501 near the top straight plate 403. The third steering wheel 503 is located on the outside of the first grinding roller 401, where "outside" refers to the side of the first grinding roller 401 near the T-beam template 10.

[0053] One end of the first wire rope 504 is connected to the first outer end 4031 of the top straight plate 403, and the other end passes sequentially around the top of the third steering wheel 503, the top of the first steering wheel 501, the counterweight block 301, and the top of the second steering wheel 502, and extends toward the bottom arc plate 404.

[0054] When the equipment truss 1 has not moved to the partition of the T-beam template 10, the electromagnetic device 302 is de-energized and the counterweight 301 falls. At this time, the counterweight 301 drives the first steel wire rope 504 segment located between the first steering wheel 501 and the third steering wheel 503 to move away from the side wall of the T-beam template 10. The first steel wire rope 504 segment between the third steering wheel 503 and the first outer end 4031 of the top straight plate 403 moves towards the side wall of the T-beam template 10, and at the same time pulls the first outer end 4031 of the top straight plate 403 and the top of the first grinding roller 401.

[0055] Furthermore, the first wire rope 504 is connected to the top straight plate 403 and the bottom arc plate 404 at its two ends, respectively. While the first wire rope 504 drives the top straight plate 403 to expand outward, the bottom arc plate 404 also expands outward together. The following is a breakdown of the power process of the first wire rope 504 driving the bottom arc plate 404 to expand outward:

[0056] See Figure 5 , Figure 7 The bottom arc plate 404 includes an inner side facing the first grinding roller 401. The wire rope assembly 5 also includes a fourth steering wheel 505, which is longitudinally disposed on the inner side of the bottom arc plate 404, and the wheel surface of the fourth steering wheel 505 faces the second inner end 4042 of the bottom arc plate 404. One end of the first wire rope 504 extending toward the bottom arc plate 404 passes around the bottom of the fourth steering wheel 505 and finally connects to the second inner end 4042 of the bottom arc plate 404.

[0057] After passing over the top of the second steering wheel 502, the first wire rope 504 descends vertically and finally passes the fourth steering wheel 505, connecting to the second inner end 4042 of the bottom arc plate 404. When the counterweight 301 falls and the top straight plate 403 expands outward, the first wire rope 504 segment between the second steering wheel 502 and the fourth steering wheel 505 is in an upward state. Due to the steering of the fourth steering wheel 505, the first wire rope 504 segment between the fourth steering wheel 505 and the second inner end 4042 of the bottom arc plate 404 acts as a lateral force that pulls the second inner end 4042 of the bottom arc plate 404 toward the fourth steering wheel 505. Due to the L-shaped shape of the bottom arc plate 404, while the second inner end 4042 moves, the second outer end 4041 drives the bottom of the first grinding roller 401 to approach the inner wall of the T-beam template 10.

[0058] When the equipment truss 1 moves to the partition of the T-beam template 10, the electromagnetic device 302 is energized, the counterweight 301 is attracted to the electromagnetic device 302, the falling action of the counterweight 301 stops, and the outward expansion action of the first grinding roller 401 stops.

[0059] Further details can be found here. Figure 4 , Figure 5 A first electric telescopic rod 405 is provided on the top side of the grinding roller housing 402 away from the first grinding roller 401, and the telescopic end of the first electric telescopic rod 405 faces the grinding roller housing 402. A second steel wire rope 506 is provided between the grinding roller housing 402 and the telescopic end of the first electric telescopic rod 405. A second electric telescopic rod 406 is provided at the bottom of the grinding roller housing 402. The second electric telescopic rod 406 is located on the side of the grinding roller housing 402 away from the first grinding roller 401, and the telescopic end of the second electric telescopic rod 406 faces the fourth steering wheel 505. A fifth steering wheel 507 is horizontally provided between the second electric telescopic rod 406 and the fourth steering wheel 505. A third steel wire rope 508 is provided on the second electric telescopic rod 406, with one end connected to the telescopic end of the second electric telescopic rod 406 and the other end passing through the fifth steering wheel 507 and connected to the second outer end 4041 of the bottom arc plate 404.

[0060] The first electric telescopic rod 405 and the second electric telescopic rod 406 are mainly used to retract the first grinding kit 4. When the first grinding roller 401 is extended and approaches the inner wall of the T-beam template 10, the grinding roller housing 402 moves accordingly and pulls the first electric telescopic rod 405 out through the second wire rope 506. At the same time, the second outer end 4041 of the bottom arc plate 404 pulls out the telescopic end of the second electric telescopic rod 406 through the third wire rope 508. When the grinding work is finished and the first grinding kit 4 needs to be retracted, the first electric telescopic rod 405 automatically retracts, pulling the first grinding roller through the second wire rope 506. The top of 401, the grinding roller housing 402, and the first outer end 4031 of the top straight plate 403 move simultaneously away from the inner wall of the T-beam mold. The movement of the first outer end 4031 can pull the first steel wire rope 504 to pull up and reset the counterweight 301. At the same time, the telescopic end of the second electric telescopic rod 406 is retracted synchronously. The third steel wire rope 508, through the steering of the fifth steering wheel 507, converts the retraction force of the second electric telescopic rod 406 into a pulling force that pulls the second outer end 4041 of the bottom arc plate 404 away from the inner wall of the T-beam template 10. At this point, the first grinding kit 4 is retracted.

[0061] Figure 8 This is a schematic diagram showing the multi-functional operating equipment for variable cross-section highway T-beam formwork entering the T-beam formwork 10 state according to this application. The usage process of the multi-functional operating equipment for variable cross-section highway T-beam formwork in this application is as follows:

[0062] The walking drive unit 6 drives the multi-functional operating equipment body to move inside the T-beam template 10. The dust collection unit 7 starts to operate. The second grinding kit 902 and the third grinding kit 903 in the top and bottom grinding unit 9 grind the upper and bottom surfaces of the T-beam template 10. When the equipment truss 1 has not moved to the partition of the T-beam template 10, the electromagnetic device 302 is de-energized, the counterweight 301 falls, and the first grinding roller 401 is pulled out by the first steel wire rope 504 and closely adheres to the inner wall of the T-beam template 10. When the equipment truss 1 moves to the partition of the T-beam template 10, the electromagnetic device 302 is energized, the counterweight 301 is attracted to the electromagnetic device 302, and the first grinding roller 401 remains in place to avoid sinking into the partition of the T-beam template 10. After the grinding work is completed, the top and bottom grinding unit 9 rises, and the spraying unit 8 begins to perform atomized spraying on the surface of the T-beam template 10.
