Description

Technical Field

[0001] This invention relates to the field of box girder engineering technology, and in particular to a trolley for tensioning and grouting. Background Technology

[0002] Currently, to ensure the reliability, safety, and service life of box girders, effective prestressing is crucial. The main quality risks of prestressed box girders stem from improper prestressing tensioning and a lack of effective grouting quality control. The establishment of effective prestressing directly affects the safety, reliability, and service life of the box girder. Prestressing construction consists of two steps: prestressing tensioning and duct grouting. First, the tensioning accuracy of the prestressing tendons is controlled using tensioning equipment; then, grout is applied into the ducts to encapsulate the prestressing tendons.

[0003] Both the tensioning and grouting of prestressed tendons are continuous processes, requiring equipment to operate at full load for extended periods. This can easily lead to overheating of the tensioning and grouting equipment. Furthermore, since both prestressed tendon tensioning and grouting are outdoor operations, workers frequently face high-temperature environments.

[0004] Regarding the aforementioned technologies, if the tensioning equipment and grouting equipment are continuously exposed to hot and humid environments, they are prone to burnout. Summary of the Invention

[0005] In order to improve the problem of easy burnout of tensioning and grouting equipment, this application provides a trolley for tensioning and grouting.

[0006] This application provides a tensioning and grouting trolley, which adopts the following technical solution: A trolley for tensioning and grouting includes a hollow base, a horizontal beam plate horizontally disposed above the hollow base, a vertical beam plate vertically disposed on the top of the hollow base, an arc-shaped plate fixed between the horizontal beam plate and the vertical beam plate, a tensioning component disposed at the bottom of the horizontal beam plate for tensioning the prestressing tendons of the box girder, and a grouting component disposed at the top of the hollow base for grouting the prestressing tendons of the box girder. The side wall of the vertical beam plate near the box girder is provided with a heat dissipation groove, and a condenser pipe is installed on the vertical beam plate through the heat dissipation groove.

[0007] By adopting the above technical solution, the condensate in the condenser pipe can dissipate heat for the grouting and tensioning equipment, while also providing coolness for the staff.

[0008] Optionally, the grouting component includes a cement tank located on top of the hollow base, a mixing tank rotatably mounted on top of the hollow base, an electronic weighing device rotatably mounted on top of the mixing tank, an auger conveyor connected between the electronic weighing device and the cement tank, and a storage box located inside the hollow base for storing slurry; the hollow plate and the storage box are connected by a corrugated hose.

[0009] By adopting the above technical solution, the auger conveyor transfers cement from the cement silo to the electronic weighing device. After the electronic weighing device weighs the cement to the appropriate weight, it is poured into the mixing tank, and then the appropriate water source is poured into the mixing tank. This can minimize the difference in the cement and water ratio each time.

[0010] Optionally, the mixing tank is provided with a water injection component, which includes a hollow disc rotatably mounted on the bottom of the mixing tank, a main shaft tube coaxially fixed to the hollow disc, and several branch shaft tubes fixed to the periphery of the main shaft tube; the part where the hollow disc is connected to the mixing tank is in communication, and the several branch shaft tubes are all connected to the main shaft tube, and several water spray nozzles are provided on the periphery of the branch shaft tubes.

[0011] By adopting the above technical solution, the water source of the water turbine motor flows to the main shaft pipe through the water pipe, and the water source in the main shaft pipe flows into the mixing tank through the branch shaft pipe, thereby achieving the effect of the water source being evenly mixed into the cement.

[0012] Optionally, the mixing tank is equipped with a mixing component for mixing water and cement. The mixing component includes several mixing rods that are horizontally fixed to the inner circumference of the mixing tank, and the several mixing rods are arranged interlaced with several split-shaft pipes.

[0013] By adopting the above technical solution, the stirring rod and the branch shaft pipe on the side of the main shaft pipe in the mixing tank move relative to each other to stir the water and cement, so that the water and cement are fully mixed.

[0014] Optionally, the top of the hollow base is provided with a driving component for driving the mixing tank to rotate. The driving component includes a water turbine motor located on the top of the hollow base, a gear ring coaxially fixed to the periphery of the mixing tank, and a gear coaxially fixed to the output shaft of the water turbine motor. The gear ring meshes with the gear, and a power component for driving the water turbine motor is provided inside the hollow base.

[0015] By adopting the above technical solution, the output shaft of the water turbine motor rotates through the power component, and the output shaft of the water turbine motor drives the gear to rotate, thereby achieving the effect of the gear driving the mixing tank to rotate through the gear ring meshing with it.

[0016] Optionally, the power component includes a water storage tank fixed to the bottom surface of the hollow base and a booster pump fixed to the inner wall of the hollow base; the inlet of the booster pump is connected to the water storage tank, the outlet of the booster pump is connected to the inlet of the water turbine motor, and the outlet of the water turbine motor is connected to the main shaft pipe through water pipes.

[0017] By adopting the above technical solution, the water storage tank uses a booster pump to inject water into the water turbine motor. The output shaft of the water turbine motor rotates under the action of water power, which drives the gear to rotate. The gear drives the mixing tank to rotate through the meshing gear ring. The water in the water turbine motor flows to the main shaft pipe through the water pipe, and the water in the main shaft pipe flows into the mixing tank through the branch shaft pipe, thereby achieving the effect of uniformly mixing the water into the cement.

[0018] Optionally, the hollow base is provided with a filling component for filling condensate into the condenser pipe. The filling component includes a condensation tank located on top of the water storage tank, a first conduit connecting the inlet of the condenser pipe to the condensation tank, and a second conduit connecting the outlet of the condenser pipe to the condensation tank. A condensate pump is installed around the first conduit. The condensation tank is connected to the top of the water storage tank. The panels around the condensation tank and at the bottom are provided with cavities and are connected. The condensation tank is connected to an existing condensate storage device.

[0019] By adopting the above technical solution, the condensate storage device injects condensate into the cavity of the condensation box through the filling port, thereby achieving the effect of cooling the water source inside the condensation box with condensate; the condensed water source is pressurized by the condensate pump and transmitted through the first conduit and injected into the condenser pipe; the condensate in the condenser pipe is transmitted back to the condensation box through the second conduit, so as to achieve a closed loop of condensate in the condenser pipe and the condensate in the condensation box.

[0020] Optionally, the storage tank is provided with a cleaning component for scraping off the adhered mud. The cleaning component includes several hydraulic sleeves disposed on opposite side walls of the storage tank, a hydraulic guide column passing through the hydraulic sleeves, a scraper fixed to the end of the hydraulic guide column located inside the storage tank, and a hydraulic piston fixed to the end of the hydraulic guide column located inside the hydraulic sleeves. The hollow base is provided with a hydraulic component for driving the hydraulic guide column to slide.

[0021] By adopting the above technical solution, the hydraulic component pushes the hydraulic piston inside the hydraulic sleeve, which in turn pushes the hydraulic guide column, thereby achieving the effect of the hydraulic guide column driving the scraper to clean the residual mud to the discharge port of the storage tank.

[0022] Optionally, the hydraulic components include a drive rod vertically fixed to the bottom of the storage tank, a condensing piston fixed to the end of the drive rod located inside the condensing tank, and a compression spring connecting the storage tank and the condensing tank; several hydraulic sleeves are connected to the condensing tank via corrugated hoses.

[0023] By adopting the above technical solution, the slurry inside the storage box is used to fill the channels of the prestressing tendons of the box girder. As the slurry decreases, the weight of the storage box decreases. The storage box rises continuously due to the action of the compression spring. The storage box drives the condensing piston to move vertically upward through the drive rod and squeezes the condensate in the condensing box, thereby achieving the effect of the condensate in the condensing box flowing to the hydraulic sleeve through the water pipe.

[0024] Optionally, the tensioning component includes several linear guide rails fixed to the bottom of the crossbeam plate, an electric hoist slidably installed at the bottom of the linear guide rails, and a through-hole jack hoisted at the bottom of the electric hoist.

[0025] By adopting the above technical solution, the electric hoist is started and drives the through-hole jack to move to the appropriate position of the box girder, thereby realizing the effect of the through-hole jack to tension the prestressing tendons of the box girder.

[0026] In summary, this application includes at least one of the following beneficial technical effects: 1. The water storage tank uses a booster pump to fill the water turbine motor with water. The output shaft of the water turbine motor rotates under the action of water power. The output shaft of the water turbine motor drives the gear to rotate. The gear drives the mixing tank to rotate through the meshing gear ring. The water source flows to the main shaft pipe through the water pipe. The water source in the main shaft pipe flows into the mixing tank through the branch shaft pipe, thereby achieving the effect of uniformly mixing the water source into the cement. 2. The condensate storage device injects condensate into the cavity of the condensation box through the filling port, thereby achieving the effect of cooling the water source inside the condensation box with the condensate; 3. As the mud decreases, the weight of the storage tank decreases. The storage tank rises continuously due to the action of the compression spring. The storage tank drives the condensing piston to move vertically upward through the drive rod and squeezes the condensate in the condensing tank. This achieves the effect of the condensate in the condensing tank flowing to the hydraulic sleeve through the water pipe. Attached Figure Description

[0041] Reference Figure 3 , Figure 6 and Figure 7A first conduit 39 connects the inlet of the condenser pipe 20 to the top of the condenser box 37, and a condensate pump 40 is installed around the first conduit 39. A second conduit 41 connects the outlet of the condenser pipe 20 to the top of the condensate pipe, and a one-way valve 42 is installed around the second conduit 41, allowing the condensate from the condenser pipe 20 to flow unidirectionally into the condenser box 37.

These four sliders 45 correspond one-to-one with four guide rods 44, and the guide rods 44 pass through their respective sliders 45, allowing the storage box 43 to slide along the length of the guide rods 44 within the hollow base 11. The hollow disk 32 is connected to the bottom of the storage box 43 via a corrugated flexible hose. A drive rod 46 is vertically fixed to the bottom of the storage box 43. The bottom end of the drive rod 46 passes through the condenser box 37 and is fixed with a condenser piston 47. The condenser piston 47 fits snugly against the side walls of the condenser box 37. A compression spring 48 connects the storage box 43 and the condenser box 37, and the compression spring 48 is sleeved around the drive rod 46.

[0042] Reference Figure 6 and Figure 8 Hydraulic sleeves 49 are fixed horizontally on both sides of the storage tank 43. Hydraulic guide posts 50 pass through each hydraulic sleeve 49 along its length. One end of the hydraulic guide post 50 passes through the storage tank 43 and is fixedly fitted with a scraper 51. The other end of the hydraulic guide post 50 is fixedly fitted with a hydraulic piston 52. The scraper 51 is in contact with the side walls of the storage tank 43, and the outer circumference of the hydraulic piston 52 is in contact with the inner circumference of the hydraulic sleeve 49. Both hydraulic sleeves 49 are connected to the condenser 37 via corrugated hoses. The junction of the corrugated hose and the hydraulic sleeve 49 is located on the side of the hydraulic piston 52 away from the hydraulic guide post 50.

[0043] The implementation principle of the tensioning and grouting trolley disclosed in this application embodiment is as follows: First, the electric hoist 17 is gradually brought closer to the box girder 53 by the linear guide rail 16. Then, the electric hoist 17 is started and drives the through-hole jack 18 to move to the appropriate position of the box girder 53. The through-hole jack 18 performs the operation of tensioning the prestressing tendons of the box girder 53.

[0044] While tensioning is underway, workers need to pour the prepared mud slurry into the mixing tank 23. The mud slurry in the mixing tank 23 is then poured into the storage tank 43 through a corrugated hose. This causes the storage tank 43 to slide and descend due to its increased weight, until the storage tank 43, driven by the drive rod 46, moves the condensing piston 47 to the bottom of the condensing tank 37. Simultaneously, while the existing water filling equipment pours water into the storage tank 27, the solenoid valve between the condensing tank 37 and the storage tank 27 opens, allowing water from the storage tank 27 to be poured into the condensing tank 37 through a water pipe. When both the condensing tank 37 and the storage tank 27 are full, the solenoid valve between them closes to minimize the backflow of condensate from the condensing tank 37 into the storage tank 27. At the same time, the existing condensate storage equipment pours condensate into the cavity of the condensing tank 37 through the filling port 38, thereby achieving the effect of cooling the water inside the condensing tank 37.

[0045] The condensed water is pressurized by the condensate pump 40 and transmitted through the first conduit 39 to the condenser pipe 20. The condensate in the condenser pipe 20 is then transmitted through the second conduit 41 back to the condenser box 37, thus forming a closed loop between the condenser pipe 20 and the condenser box 37. The condensate in the condenser pipe 20 not only dissipates heat for the grouting equipment but also provides coolness for the workers. The auger conveyor 26 starts, transferring cement from the cement tank 22 to the electronic weighing device 25. After the electronic weighing device 25 weighs the cement to the appropriate weight, it is poured into the mixing tank 23. At the same time, the water storage tank 27 is pressurized by the booster pump 36 to fill the water turbine motor 28. The output shaft of the water turbine motor 28 rotates under the action of water power, driving the gear 29 to rotate. The gear 29, through the meshing gear ring 30, drives the mixing tank 23 to rotate.

[0046] Water from the turbine motor 28 flows through a water pipe to the main shaft pipe 33, and water from the main shaft pipe 33 flows into the mixing tank 23 through the branch shaft pipe 34, thus achieving the effect of uniformly mixing the water into the cement. The stirring rod 35 in the mixing tank 23 and the branch shaft pipe 34 around the main shaft pipe 33 move relative to each other to stir the water and cement, so that the water and cement are fully mixed. The mixed slurry is injected into the storage tank 43 through a corrugated hose. The slurry inside the storage tank 43 is used to fill the channels of the prestressed tendons of the box girder 53. As the slurry decreases, the weight of the storage tank 43 decreases. The storage tank 43 rises continuously under the action of the compression spring 48. The storage tank 43 drives the condensing piston 47 to move vertically upward through the drive rod 46 and squeezes the condensate in the condensing tank 37. The condensate in the condensing tank 37 flows to the hydraulic sleeve 49 through the water pipe. The condensate inside the hydraulic sleeve 49 pushes the hydraulic guide column 50 through the hydraulic piston 52. The hydraulic guide column 50 drives the scraper 51 to clean the residual slurry to the discharge port of the storage tank 43.

[0047] The above are all preferred embodiments of this application, and are not intended to limit the scope of protection of this application. Therefore, all equivalent changes made in accordance with the structure, shape and principle of this application should be covered within the scope of protection of this application.
