Description

Technical Field

[0001] This utility model relates to the field of grouting equipment technology, specifically to a grouting trolley. Background Technology

[0002] Post-tensioned precast box girders are a widely used concrete beam structure. Their core principle is to use the tensioning of prestressed steel strands to generate reverse pressure, thereby counteracting the tensile stress generated by the loads borne by the beam during its service life. This construction method effectively improves the crack resistance, stiffness, and durability of the beam, ensuring its stability and safety even under heavy loads. For post-tensioned precast box girder construction, corrugated metal pipes need to be embedded during concrete pouring to create channels in the concrete beam for the prestressed steel strands. After the concrete reaches its design strength, the prestressed steel strands are tensioned, and then the channels are grouted to seal them, ensuring a firm bond between the prestressed steel strands and the concrete box girder, forming a complete load-bearing system. Therefore, the quality of the grout not only affects the degree of bonding between the prestressed steel strands and the precast box girder, but also determines the isolation effect of the prestressed steel strands.

[0003] A grouting trolley is a construction device that integrates grout preparation and transportation. This equipment mainly includes a mixing and grouting system, a mixing and storage system, and a grouting system. The mixing and grouting system thoroughly mixes cement, water, and other additives to form a grout that meets construction requirements. The mixing and storage system temporarily stores the mixed grout and continuously mixes it to prevent stratification or solidification, thus ensuring a constant supply for grouting operations. The grouting system is responsible for transporting the grout into the ducts of the box girder to complete the grouting operation. To ensure grout quality and prevent large particles from entering the grout, a screen is installed at the feed point of the mixing and storage system to remove large particles, thus ensuring grout quality. For easy observation and cleaning of the screen, an external mounting method is used, where the screen is installed above the mixing and storage system. This allows the screened grout to fall directly into the mixing and storage system, facilitating observation of the screening effect and making cleaning the screen using a high-pressure water gun or special tools more convenient. However, cleaning the screen using a high-pressure water gun or other tools requires temporarily shutting off the slurry delivery to the mixing and storage system. If the cleaning process is too time-consuming, it can easily negatively impact the continuity and efficiency of the grouting operation. Furthermore, because the screen has a plate-like structure, slurry falling onto it is prone to splashing out, affecting the slurry delivery to the mixing and storage system and causing pollution to the surrounding area. Therefore, the grouting trolley has shortcomings. Improving the grouting trolley can reduce slurry splashing and minimize the impact of screen cleaning on slurry delivery, thereby improving overall construction efficiency and slurry quality, and ensuring the smooth progress of the project.

[0004] Furthermore, due to the plate-like structure of the screen, slurry falling onto the screen is not only prone to splashing out, but also easily slides off the edges of the screen, thus affecting the slurry's delivery to the mixing and storage system and its quality. The splashed slurry can also cause pollution to the surrounding area. Therefore, the grouting trolley has shortcomings. By improving the grouting trolley, slurry splashing can be reduced, and the impact of screen cleaning on slurry delivery can be minimized, thereby improving overall construction efficiency and slurry quality, and ensuring the smooth progress of the project. Summary of the Invention

[0005] In view of the shortcomings of the prior art, this utility model provides a grouting trolley that reduces slurry splashing and minimizes the impact of cleaning on slurry transportation, thereby overcoming the defects in the prior art.

A valve body is set at the bottom end of the grouting and mixing tank, and the grouting and mixing tank is connected to the grout storage and mixing tank through the valve body. A sieve box with an open top is set below the valve body, and the sieve box has several sieve holes. Two fixing plates are set on the top of the grout storage and mixing tank, and the two fixing plates respectively contact the outer walls of the two sides of the sieve box. The fixing plates are equipped with... There are two support plates, which are respectively installed on the outer walls of the two sides of the screen box. The two fixed plates are respectively provided with locking mechanisms. The locking mechanism includes a locking box with a top opening, a fixing block fitted inside the locking box, and a spring set below the fixing block. The spring is located inside the locking box, and its two ends are respectively connected to the bottom end of the fixing block and the bottom plate of the locking box. The fixed plate has a fixing hole, and the fixing block is fitted into the fixing hole. The inner cavity cross section of the fixing hole matches the shape cross section of the fixing block. The top of the fixing block protrudes from the fixing hole. The support plate is located between the top of the fixing block and the side wall of the slurry mixing tank.

[0007] Preferably, a pad made of elastic material is provided between the support plate and the fixed plate. The pad is installed on the bottom surface of the support plate, and both sides of the pad are in contact with the support plate and the fixed plate, respectively. A block made of elastic material is provided between the screen box and the side wall of the slurry mixing tank. The block is installed on the outer wall of the screen box and is in contact with the side wall of the slurry mixing tank. The side of the support plate away from the block is in contact with the fixed block. A discharge trough is provided at the top of the screen box. A guide plate is obliquely fitted inside the discharge trough. The top of the guide plate is installed on the screen box. The guide plate is located between the two fixed plates and is located on the side of the screen box away from the block.

[0008] Preferably, a round rod is provided above the support plate, and a reinforcing plate is provided at both ends of the round rod. The reinforcing plate is installed on the round rod, the bottom end of the reinforcing plate is installed on the support plate, and one side of the reinforcing plate is installed on the sieve box.

[0009] Preferably, the fixing block adopts a rectangular structure, the horizontal cross-sectional shape of the fixing block matches the horizontal cross-sectional shape of the inner cavity of the locking box, and a guide groove is inclinedly opened at the top of the fixing block, the height of the guide groove gradually increases along the direction away from the support plate.

[0010] Preferably, the bottom plate of the sieve box is designed to be inclined, and the bottom plate of the sieve box gradually decreases along the direction close to the fixed block, thus utilizing the inclined design of the bottom plate of the sieve box.

[0011] Preferably, the top of the slurry storage mixing tank and the slurry preparation mixing tank are respectively provided with a frame, and a stirring motor is provided on the frame. The stirring motor is mounted on the slurry storage mixing tank or the slurry preparation mixing tank through the frame. The drive end of the stirring motor is connected to a stirring shaft, which is located inside the slurry storage mixing tank or the slurry preparation mixing tank. One end of the fixing plate is installed on the top of the side wall of the slurry storage mixing tank, and the other end of the fixing plate is connected to the frame on which the slurry storage mixing tank is mounted.

[0012] Preferably, an auger conveyor is inclinedly arranged above the chassis, and a fixed frame is provided on the auger conveyor. The auger conveyor is mounted on the chassis through the fixed frame. The output end of the auger conveyor is located above the input end of the auger conveyor. The output end of the auger conveyor is connected to the inner cavity of the pulping and mixing tank. A hopper is provided on the input end of the auger conveyor, and the bottom end of the hopper is installed on the input end of the auger conveyor. The hopper is connected to the inner cavity of the auger conveyor.

[0013] The beneficial effects of this utility model are as follows: First, this utility model replaces the screen with a screen box that has an opening at the top. The side wall of the screen box blocks the splashing slurry, thereby reducing the splashing phenomenon. Two fixing plates set at the top of the slurry storage and mixing tank limit the two sides of the screen box. Then, two support plates set on the screen box are used to support the support plates with the fixing plates, so that the screen box is assembled between the two fixing plates. Therefore, when the screen box needs to be cleaned, it is replaced with the screen box assembled between the two fixing plates, which greatly reduces the impact of cleaning on the slurry transportation. Then, the removed screen box is cleaned so that it can be replaced and used again. Furthermore, this utility model constrains the fixing block through the locking box and spring, so that when the fixing block is squeezed by the support plate, the fixing block moves towards the bottom of the locking box, that is, the top of the fixing block moves into the fixing hole or the locking box. After the support plate moves between the fixing block and the side wall of the slurry mixing tank, the fixing block is released from the squeezing action and resets under the action of the spring, so as to restrict the support plate between the fixing block and the side wall of the slurry mixing tank, so as to quickly lock the screen box between the fixing block and the side wall of the slurry mixing tank, thereby meeting the needs of loading and unloading the screen box.

[0014] Secondly, this invention utilizes a pad on the support plate to cushion the support plate against the fixed plate, reducing the impact on the support plate. The pads also press the support plate and screen box between the slurry mixing tank and the fixed block, preventing the screen box from contacting the side wall of the mixing tank and thus avoiding blockage of the screen holes on one side of the screen box. A discharge chute at the top of the screen box, along with a guide plate inside, allows excess slurry to drain through the guide plate, preventing leakage from the top opening. Furthermore, a reinforcing plate strengthens the connection between the support plate and the screen box, improving the stability of the support plate. A round rod mounted on the reinforcing plate serves as a handle, allowing movement of the support plate and screen box.

[0015] Furthermore, this invention utilizes a guide groove at the top of the fixed block to guide the support plate placed between the top of the fixed block and the side wall of the slurry mixing tank. The bottom plate of the screen box is designed with an incline, gradually decreasing in elevation towards the fixed block. This not only buffers the impact of the slurry discharged from the valve body but also uses this impact to push the screen box against the side wall of the slurry mixing tank, reducing screen box sway and improving screening stability. Moreover, this invention uses a frame mounted on the slurry mixing tank or pulping mixing tank to mount the mixing motor. The mixing shaft mounted on the motor mixes the material filling the tank. A fixed plate is mounted between the side wall of the tank and the frame to prevent interference between mixing and slurry transport. An auger conveyor and hopper facilitate the transport of powder into the pulping mixing tank, making feeding more convenient. Attached Figure Description

The grout mixing tank 5 is mounted on the chassis 1 via the support 6. The grout in the grout storage and mixing tank 3 is discharged by the grouting pump 4, allowing the grout in the grout storage and mixing tank 3 to be transported into the ducts of the concrete beam. A valve body 7 is provided at the bottom of the pulping mixing tank 5, which is connected to the pulp storage mixing tank 3 through the valve body 7. Below the valve body 7 is a screen box 8 with an open top, and the screen box 8 has several screen holes 9 to screen out large particles of impurities, thereby improving the quality of the pulp. Two fixing plates 10 are provided at the top of the pulp storage mixing tank 3, both of which are mounted on the tank and contact the outer walls of the screen box 8 on both sides. Two support plates 11 are provided on the fixing plates 10, and are mounted on the outer walls of the screen box 8 on both sides, thus using the support plates 11 to assemble the screen box 8 between the two fixing plates 10, making cleaning and replacement of the screen box 8 more convenient. A locking mechanism is provided on each of the two fixing plates 10; the locking mechanism includes a locking box 12 with an open top, a fixing block 13 fitted inside the locking box 12, and a spring 14 located below the fixing block 13. The spring 14 is located inside the locking box 12. The two ends of 4 are respectively connected to the bottom end of the fixing block 13 and the bottom plate of the locking box 12. The fixing plate 10 has a fixing hole 15. The fixing block 13 is fitted into the fixing hole 15. The inner cavity cross section of the fixing hole 15 matches the shape cross section of the fixing block 13. The top of the fixing block 13 protrudes from the fixing hole 15. The support plate 11 is located between the top of the fixing block 13 and the side wall of the slurry mixing tank 3 to constrain the movement of the support plate 11 so as to lock the support plate 11 on the fixing plate 10.

[0021] In this embodiment, a pad 16 made of elastic material is provided between the support plate 11 and the fixed plate 10. The pad 16 is installed on the bottom surface of the support plate 11, and both sides of the pad 16 are in contact with the support plate 11 and the fixed plate 10, respectively, so that the fixed plate 10 provides cushioning for the support plate 11, thereby reducing the impact on the support plate 11. A pad 17 made of elastic material is provided between the screen box 8 and the side wall of the slurry mixing tank 3. The pad 17 is installed on the outer wall of the screen box 8 and is located between adjacent screen holes 10 to avoid affecting the screening. The pad 17 is in contact with the side wall of the slurry mixing tank 3, and the side of the support plate 11 away from the pad 17 is in contact with the fixed block 13, thereby using the... The pad 17 presses the support plate 11 and the screen box 8 between the slurry mixing tank 3 and the fixing block 13, and prevents the screen box 8 from contacting the side wall of the slurry mixing tank 3, that is, prevents the screen holes 9 on one side of the screen box 8 from being blocked by the side wall of the slurry mixing tank 3; the top of the screen box 8 is provided with a discharge groove 18, and a guide plate 19 is inclinedly installed in the discharge groove 18. The top of the guide plate 19 is installed on the screen box 8, and the guide plate 19 is located between the two fixing plates 10. The guide plate 19 is located on the side of the screen box 8 away from the pad 17, and the bottom end of the guide plate 19 is located above the inner cavity of the slurry mixing tank 3, so that when there is too much slurry in the screen box 8, the slurry is discharged through the guide plate 19, preventing the slurry from leaking out from the top opening of the screen box 8.

[0022] Please refer to it again. Figure 2 and 3 A round rod 20 is provided above the support plate 11, and a reinforcing plate 21 is provided at both ends of the round rod 20. The reinforcing plate 21 is installed on the round rod 20, the bottom end of the reinforcing plate 21 is installed on the support plate 11, and one side of the reinforcing plate 21 is installed on the sieve box 8. Thus, the reinforcing plate 21 is used to reinforce the connection between the support plate 11 and the sieve box 8, so as to improve the stability of the support plate 11 supporting the sieve box 8. The round rod 20 serves as a handle, and the support plate 11 and the sieve box 8 can be moved by holding the round rod 20.

[0023] Specifically, the fixing block 13 adopts a rectangular structure, and the horizontal cross-sectional shape of the fixing block 13 matches the horizontal cross-sectional shape of the inner cavity of the locking box 12 to avoid the fixing block 13 from rotating. The top of the fixing block 13 is provided with a guide groove 22 at an angle. The height of the guide groove 22 gradually increases along the direction away from the support plate 11 so that the support plate 11 can be placed between the top of the fixing block 13 and the side wall of the slurry mixing tank 3.

[0024] In this embodiment, the bottom plate of the screen box 8 is designed with an inclination. The bottom plate of the screen box 8 gradually decreases along the direction close to the fixing block 13. The inclination design of the bottom plate of the screen box 8 can buffer the impact force of the slurry discharged from the valve body 7 falling, and use the impact force to push the screen box 8 towards the side wall of the slurry storage and mixing tank 3 to reduce the shaking of the screen box 8 and improve the stability of screening.

[0025] Please refer to it again. Figure 1 and 2 The top of the slurry storage mixing tank 3 and the slurry mixing tank 5 are respectively provided with a frame 23. The frame 23 is equipped with a stirring motor 24. The stirring motor 24 is installed on the slurry storage mixing tank 3 or the slurry mixing tank 5 through the frame 23. The driving end of the stirring motor 24 is connected to a stirring shaft, which is located inside the slurry storage mixing tank 3 or the slurry mixing tank 5. By controlling the operation of the stirring motor 24, the stirring shaft is driven to rotate, thereby mixing the materials in the slurry storage mixing tank 3 or the slurry mixing tank 5. One end of the fixing plate 10 is installed on the top of the side wall of the slurry storage mixing tank 3, and the other end of the fixing plate 10 is connected to the frame 23 installed on the slurry storage mixing tank 3, so as to assemble the fixing plate 10 between the side wall of the slurry storage mixing tank 3 and the frame 23.

[0026] In this embodiment, an auger conveyor 25 is inclinedly arranged above the chassis 1. The auger conveyor 25 includes a pipe with openings at both ends, a conveying motor installed on the pipe, and a spiral blade installed on the conveying motor. The spiral blade is located inside the pipe. By controlling the operation of the conveying motor, the spiral blade is driven to rotate, thereby conveying the powder in the pipe. A fixing frame 26 is provided on the auger conveyor 25, and the auger conveyor 25 is installed on the chassis 1 through the fixing frame 26. The output end of the auger conveyor 25 is located above the input end of the auger conveyor 25 and is connected to the inner cavity of the pulping and mixing tank 5. A hopper 27 is provided on the input end of the auger conveyor 25. The bottom end of the hopper 27 is installed on the input end of the auger conveyor 25 and is connected to the inner cavity of the auger conveyor 25 so that the powder added to the hopper 27 can be conveyed into the pulping and mixing tank 5 by the auger conveyor 25. The number of screw conveyors 25 and hoppers 27 is several, so that various powders can be added into the pulping and mixing tank 5 respectively.

[0027] The instructions for using this product are as follows: Figures 1 to 4As shown, firstly, according to the required slurry proportions, the powder material previously placed in the hopper 27 is gradually conveyed to the slurry mixing tank 5 via the auger conveyor 25. Then, a pre-set amount of water and an appropriate amount of additives are added to the slurry mixing tank 5. By starting the stirring motor 24 mounted on the slurry mixing tank 5, the materials in the slurry mixing tank 5 are thoroughly stirred and mixed to prepare a slurry that meets the requirements. Secondly, by holding the round rod 20, the screen box 8 is placed between the two fixed plates 10, ensuring that the support plate 11 is securely mounted on the fixed plate 10 via the pad 1. By moving the support plate 11 between the fixed block 13 and the slurry storage mixing tank 3, the slurry output from the valve body 7 is conveyed to the slurry storage mixing tank 3 after being screened by the screen box 8. Next, by opening valve 7 and starting the mixing motor 24 installed on the grout storage mixing tank 3, the grout prepared in the mixing tank 5 is gradually transported into the grout storage mixing tank 3; and the grout transported into the grout storage mixing tank 3 is continuously stirred. Then, by controlling the grouting pump 4, the uniformly stirred grout in the grout storage mixing tank 3 is smoothly transported into the duct of the concrete box girder, ensuring that the grout is densely filled and achieving the expected construction effect.

[0028] In this embodiment, a screen box 8 with a top opening replaces the screen mesh. The side walls of the screen box 8 block splashing slurry, thereby reducing slurry splashing. Two fixing plates 10 set on the top of the slurry storage and mixing tank 3 limit the two sides of the screen box 8. Two support plates 11 set on the screen box 8 are supported by the fixing plates 10. The screen box 8 is assembled between the two fixing plates 10. When the screen box 8 needs to be cleaned, it is replaced with the screen box 8 assembled between the two fixing plates 10. This greatly reduces the impact of cleaning on slurry transportation. The removed screen box 8 is then cleaned for reuse. Furthermore, this utility model constrains the fixing block 13 by setting the locking box 12 and the spring 14, so that when the fixing block 13 is squeezed by the support plate 11, the fixing block 13 moves toward the bottom end of the locking box 12, that is, the top of the fixing block 13 moves into the fixing hole 15 or the locking box 12. After the support plate 11 moves between the fixing block 13 and the side wall of the slurry mixing tank 3, the fixing block 13 is released from the squeezing action and resets under the action of the spring 14, so as to restrict the support plate 11 between the fixing block 13 and the side wall of the slurry mixing tank 3, so as to quickly lock the screen box 8 between the fixing block 13 and the side wall of the slurry mixing tank 3, thereby meeting the loading and unloading needs of the screen box 8.

[0029] The embodiments described above are merely preferred embodiments of this utility model and are not intended to limit the scope of implementation of this utility model. Therefore, all equivalent changes or modifications made to the structure, features and principles described in the patent claims of this utility model should be included within the scope of the patent application of this utility model.
