Description

Technical Field

[0001] This utility model relates to the field of concrete pouring technology, and more specifically, to a concrete pouring guide device. Background Technology

[0002] Currently, during concrete pouring, a flow guiding device is typically installed below the concrete outlet to direct the concrete to the desired location. This device usually consists of a grooved plate structure. For example, patent (publication number: CN221119239U) discloses a flow guiding device for concrete pouring, including a chute for conveying concrete and a base supporting the chute. The upper end of the base has a support cylinder, and a telescopic rod is inserted into the upper end of the support cylinder. The lower end of the chute is connected to a rotating rod, which is connected to the telescopic rod via a connecting sleeve. The rotating rod and the connecting sleeve rotate in a rotatable engagement. A locking mechanism that engages with the connecting sleeve is provided on the side wall of the rotating rod. This locking mechanism allows for angle adjustment and fixation of the chute, avoiding the tedious manual handling and adjustment. This not only saves manpower but also prevents concrete from sticking to clothing during handling. It is convenient to adjust, easy to use, time-saving, labor-saving, and improves work efficiency.

[0003] The above-mentioned device uses a chute to guide the concrete flow. However, in a high-temperature and dry environment, as the concrete is continuously poured into the chute, the loss of moisture from the concrete is accelerated, causing the concrete to stick to the contact surface of the chute, affecting the guiding effect and making it difficult to clean. Utility Model Content

[0004] In order to overcome the above-mentioned defects of the prior art, this utility model provides a concrete pouring guide device to solve the problem that in a high-temperature and dry environment, the continuous pouring of concrete into the chute will accelerate the loss of concrete moisture, causing the concrete to stick to the contact surface of the chute, affecting the guiding effect and making it inconvenient to clean.

[0005] To solve the above-mentioned technical problems, this utility model provides the following technical solution: a concrete pouring guide device, including a guide plate, mounting frames symmetrically fixedly installed on both sides of the guide plate in the width direction, an electric telescopic rod vertically fixedly installed on the mounting frame, a slide rail fixedly connected to the telescopic end of the electric telescopic rod, a concrete scraper slidably connected on the slide rail, the concrete scraper can slide along the inner side of the guide plate for scraping concrete, toothed plates fixedly installed on the opposite surfaces of the two mounting frames, a drive motor symmetrically fixedly installed on the concrete scraper, and a moving gear fixedly installed at the output end of the drive motor, the moving gear meshing with the toothed plate.

[0006] Preferably, the extension direction of the electric telescopic rod is perpendicular to the flow direction of the guide plate, and the guide plate, slide rail and toothed plate are parallel to each other, and the middle part of the concrete scraper is a U-shaped structure adapted to the guide plate.

[0007] Preferably, the width of the toothed plate is greater than the width of the movable gear, so that the movable gear can slide up and down along the width direction of the toothed plate when the electric telescopic rod extends or retracts.

[0008] Preferably, the assembly further includes a wetting component capable of wetting the guide plate. The wetting component includes two water storage tanks and a connecting hole. The two water storage tanks and the connecting hole are symmetrically arranged on the top surface of the concrete scraper. The top of each water storage tank is provided with a water inlet, which is connected to a water supply pipe. A water passage pipe is provided on the inner side of the concrete scraper. The water storage tank is connected to the water passage pipe through the connecting hole. Push blocks are slidably connected to both ends of the water passage pipe. Sealing pistons are fixedly connected to the opposite sides of each of the two push blocks. An L-shaped rod is fixedly connected to the end of each push block away from the sealing piston. A long groove is fixedly connected to the end of the L-shaped rod away from the push block. A pin is fixedly installed at the off-center of the moving gear. The pin can slide along the inner side of the long groove. A water-absorbing pad is provided on the side of the concrete scraper near the guide plate. The water-absorbing pad can absorb water in the water passage pipe and evenly wet the inner side of the guide plate.

[0009] Preferably, when the moving gear rotates, the push block can slide back and forth along the water pipe, and the sealing piston is made of rubber.

[0010] Preferably, the absorbent pad is configured as a U-shaped structure that fits the inner side of the guide plate, and the absorbent pad is made of sponge material.

[0011] Compared with the prior art, the beneficial effects of this utility model are:

[0012] This invention uses a moving gear that meshes and rotates along the toothed plate in the forward direction. As the guide plate guides the concrete, it also drives the two ends of the concrete scraper to slide along the slide rail. The middle part of the concrete scraper scrapes the concrete along the inner side of the guide plate. The scraping direction is consistent with the concrete guiding direction, which prevents the concrete from drying and hardening and sticking to the inner side of the guide plate due to moisture loss.

[0013] This invention uses a rotating gear to drive a pusher block to slide back and forth within the water pipe. During this process, the pusher block first slides away from the connection hole, allowing the water supply pipe to supply water into the water pipe through the inlet, storage tank, and connection hole. The absorbent pad absorbs the water, and when it becomes saturated, the excess water evenly wets the inner side of the guide plate. Then, the pusher block slides in the opposite direction, causing the sealing piston to squeeze the water in the water pipe, allowing the absorbent pad to expel more water, thus improving the wetting effect on the inner side of the guide plate. Using this structure, sufficient moisture can be maintained between the inner side of the guide plate and the concrete. Simultaneously, the wetted surface reduces friction between the concrete and the guide plate, making the concrete flow more easily and reducing accumulation. Attached Figure Description

Detailed Implementation

[0021] To make the technical problems, technical solutions and advantages of this utility model clearer, a detailed description will be given below in conjunction with the accompanying drawings and specific embodiments.

[0022] As attached Figure 1 To be continued Figure 5An embodiment of this utility model provides a concrete pouring guide device, including a guide plate 1. Mounting frames 2 are symmetrically fixedly installed on both sides of the guide plate 1 in the width direction. An electric telescopic rod 3 is vertically fixedly installed on the mounting frames 2. A slide rail 4 is fixedly connected to the telescopic end of the electric telescopic rod 3. A concrete scraper 5 is slidably connected to the slide rail 4. The concrete scraper 5 can slide along the inner side of the guide plate 1 to scrape the concrete. Toothed plates 6 are fixedly installed on the opposite surfaces of the two mounting frames 2. A drive motor 7 is symmetrically fixedly installed on the concrete scraper 5. A moving gear 8 is fixedly installed at the output end of each drive motor 7, and the moving gear 8 meshes with the toothed plate 6.

[0023] Preferably, the extension direction of the electric telescopic rod 3 is perpendicular to the flow direction of the guide plate 1, and the guide plate 1, the slide rail 4 and the toothed plate 6 are parallel to each other. The middle part of the concrete scraper 5 is a U-shaped structure that is compatible with the guide plate 1, thereby minimizing the resistance of the concrete scraper 5 to the flow of concrete.

[0024] Preferably, the width of the toothed plate 6 is greater than the width of the movable gear 8, so that when the electric telescopic rod 3 extends or retracts, the movable gear 8 can slide up and down along the width direction of the toothed plate 6.

[0025] Specifically, the moving gear 8 rotates in the forward direction along the toothed plate 6 and guides the concrete flow along the guide plate 1. At the same time, it drives the two ends of the concrete scraper 5 to slide along the slide rail 4. The middle part of the concrete scraper 5 scrapes the concrete along the inner side of the guide plate 1. The scraping direction is consistent with the concrete flow direction to prevent the concrete from drying and hardening and sticking to the inner side of the guide plate 1 due to moisture loss. After completing the above operation, the electric telescopic rod 3 retracts, driving the slide rail 4 and the concrete scraper 5 to move upward, so that the middle part of the concrete scraper 5 separates from the centrally flowing concrete. At the same time, the moving gear 8 moves upward along the toothed plate 6 and maintains a meshing state. Then, the moving gear 8 rotates in the reverse direction along the toothed plate 6, driving the concrete scraper 5 back to its original position for the next concrete scraping step. Furthermore, by scraping in one direction, the thickness of the concrete scraper 5 can reduce the resistance to concrete flow.

[0026] Preferably, it also includes a wetting component 9 capable of wetting the guide plate 1. The wetting component 9 includes two water storage tanks 91 and a connecting hole 94. The two water storage tanks 91 and the connecting hole 94 are symmetrically arranged on the top surface of the concrete scraper 5. The top of the water storage tank 91 is provided with a water inlet 92, which is connected to a water supply pipe. A water pipe 93 is opened on the inner side of the concrete scraper 5. The water storage tank 91 is connected to the water pipe 93 through the connecting hole 94. Push blocks 95 are slidably connected to both ends of the water pipe 93. A sealing piston 96 is fixedly connected to each side of the push block 95. An L-shaped rod 97 is fixedly connected to the end of the push block 95 away from the sealing piston 96. A long groove 98 is fixedly connected to the end of the L-shaped rod 97 away from the push block 95. A pin 99 is fixedly installed at the off-center of the moving gear 8. The pin 99 can slide along the inner side of the long groove 98. A water-absorbing pad 910 is provided on the side of the concrete scraper 5 near the guide plate 1. The water-absorbing pad 910 can absorb the water in the water pipe 93 and evenly wet the inner side of the guide plate 1.

[0027] Specifically, when the moving gear 8 rotates, the insert 99 can drive the long groove 98 to slide back and forth in a straight line, thereby causing the push block 95 to slide back and forth along the water pipe 93. During this process, the push block 95 first slides away from the connecting hole 94, so that the water supply pipe supplies water to the water pipe 93 through the water inlet 92, the water storage tank 91 and the connecting hole 94. The water is absorbed by the water absorption pad 910. When the water absorption pad 910 is saturated, the excess water evenly wets the inner side of the guide plate 1. Then, the push block 95 slides in the opposite direction, so that the sealing piston 96 squeezes the water in the water pipe 93, so that the water absorption pad 910 can squeeze out more water, thereby improving the wetting effect on the inner side of the guide plate 1.

[0028] Preferably, when the moving gear 8 rotates, the push block 95 can slide back and forth along the water pipe 93, and the sealing piston 96 is made of rubber to improve the sealing performance of the push block 95 between the water pipes 93.

[0029] Preferably, the absorbent pad 910 is configured as a U-shaped structure that fits the inner side of the guide plate 1, and the absorbent pad 910 is made of sponge material.

[0030] The working process of this utility model is as follows:

[0031] In use, first pour concrete into the guide plate 1 for guidance. Then start the drive motor 7, which drives the moving gear 8 to rotate in the forward direction along the toothed plate 6. As the guide plate 1 guides the concrete, the two ends of the concrete scraper 5 slide along the slide rail 4. The middle part of the concrete scraper 5 scrapes the concrete along the inner side of the guide plate 1 in the same direction as the concrete flow. After the concrete scraper 5 has scraped the guide plate 1 once, the electric telescopic rod 3 retracts, which moves the slide rail 4 and the concrete scraper 5 upward, separating the middle part of the concrete scraper 5 from the centrally flowing concrete. At the same time, the moving gear 8 moves upward along the toothed plate 6 and remains engaged. Then the moving gear 8 rotates in the reverse direction along the toothed plate 6, which moves the concrete scraper 5 back to its original position for the next concrete scraping. This process is repeated.

[0032] As the moving gear 8 rotates, the insert 99 drives the long groove 98 to slide back and forth in a straight line, thereby causing the push block 95 to slide back and forth along the water pipe 93. During this process, the push block 95 first slides away from the connecting hole 94, so that the water supply pipe supplies water to the water pipe 93 through the water inlet 92, the water storage tank 91 and the connecting hole 94. The water is absorbed by the water absorption pad 910. When the water absorption pad 910 is saturated, the excess water evenly wets the inner side of the guide plate 1. Then, the push block 95 slides in the opposite direction, so that the sealing piston 96 squeezes the water in the water pipe 93, so that the water absorption pad 910 can squeeze out more water, thereby improving the wetting effect on the inner side of the guide plate 1.
