Description

Technical Field

[0001] This utility model is designed for the field of rainwater ditch construction, specifically a simple folding pouring device for rainwater ditch. Background Technology

[0002] Currently, municipal stormwater drainage systems mostly use cast-in-place stormwater channels and various prefabricated pipes. However, stormwater channels come in various forms and sizes depending on the drainage volume. Existing construction methods and techniques cannot simultaneously pour the side walls on both sides, requiring pouring in sections and on each side, which poses certain safety hazards to construction workers. The existing stormwater channel wall thickness is mostly 20 to 30 centimeters. When pouring thin-walled concrete, backhoes and manual assistance are often used, which easily causes concrete spillage, resulting in waste, high pouring difficulty, and low efficiency. At the same time, due to the small amount of concrete poured, the appearance quality after pouring is poor, requiring a lot of manual labor for repairs. Utility Model Content

[0003] In view of the above situation and to overcome the defects of the existing technology, this utility model adopts a simple folding pouring device for rainwater channels, which solves the problems of low pouring efficiency and poor pouring quality of rainwater channels in the existing technology.

[0004] The technical solution is a simple foldable pouring device for rainwater channels, including two diversion plates on the left and right. The two diversion plates are hinged to each other at their adjacent ends. Each diversion plate has a horizontal bar with its axis placed horizontally on both the front and rear sides of its outer end. Each horizontal bar is rotatably connected to a U-shaped block with its opening facing downward. Each diversion plate has a horizontal groove in the front-to-back direction at the end near the hinge axis. Each horizontal groove is equipped with a scraper that can move up and down along the horizontal groove. After the scraper moves upward out of the horizontal groove, it can move left and right against the upper surface of the diversion plate.

[0005] The right end of the drainage plate on the left is fixed with a hinge shaft, and the front and rear sides of the left end of the drainage plate on the right are respectively fixed with support plates. The hinge shaft passes through the front and rear ends of the support plate and is rotatably connected to the support plate.

[0006] A first arc-shaped plate with a downward-facing semicircular shape is fixed between the two support plates. The first arc-shaped plate is coaxial with the hinge shaft and its right end is fixedly connected to the right side drain plate. A second arc-shaped plate with a downward-facing semicircular shape is fixed to the right end of the left side drain plate. The second arc-shaped plate is coaxial with the first arc-shaped plate and its inner diameter is equal to the outer diameter of the first arc-shaped plate.

[0007] The upper front and rear sides of the guide plate are respectively fixed with baffle plates. The baffle plates can prevent material from falling from the front and rear sides of the guide plate. A first sliding groove is opened on the inner side of each baffle plate along the length of the guide plate. A second sliding groove perpendicular to the first sliding groove is opened at the end of the first sliding groove near the scraper. A sliding rod is fixed at the front and rear ends of each scraper. The sliding rod can slide up and down in the second sliding groove. When the scraper extends out of the horizontal groove, the sliding rod can slide left and right along the first sliding groove.

[0008] The scraper has a U-shaped rod with its opening facing downwards fixed on both the front and rear sides of the upper end. The two vertical rods of the U-shaped rod are located on the front and rear sides of the corresponding side baffle plate.

[0009] The upper end face of the opening of the U-shaped block is provided with a roller, and the inner ends of the two U-shaped blocks on the front side are respectively connected by a bolt through the thread, and the bolt passes through the inner end face of the U-shaped block to the opening.

[0010] This utility model has the following advantages over the prior art:

[0011] 1. This utility model enables a single concrete pouring pipe to pour concrete on both sides simultaneously by hinged ends of two diversion plates and setting them in a herringbone shape above the side wall template of the rainwater channel, which greatly improves the pouring efficiency.

[0012] 2. By allowing the two diversion plates to rotate freely around the hinge axis and the U-shaped block to rotate around the crossbar, this device can adapt to the pouring of rainwater channels of different widths and avoid assembly errors caused by construction errors, thus greatly improving the practical performance of this device.

[0013] 3. By setting scrapers on the inner end of each diversion plate and restricting the movement direction of the scrapers through the first and second chute, the operator can quickly operate the scrapers with the U-shaped rod to scrape off the residual concrete material on the diversion plate and the baffle plate, ensuring the cyclic and reusable use of this device, and greatly improving the service life and economic benefits of this device.

[0019] The specific embodiments of this utility model will be further described in detail below with reference to the accompanying drawings.

[0020] Depend on Figures 1 to 5 The present invention includes two diversion plates 1, one on the left and one on the right, with the two diversion plates 1 hinged to each other at their adjacent ends. Each diversion plate 1 has a horizontal bar 2 fixed on its outer end on both the front and rear sides, with the horizontal axis placed in front and behind. Each horizontal bar 2 is rotatably connected to a U-shaped block 3 with its opening facing downward. Each diversion plate 1 has a horizontal groove 4 in the front and rear direction at the end near the hinge axis. Each horizontal groove 4 is provided with a scraper 5 that can move up and down along the horizontal groove 4. After the scraper 5 moves upward out of the horizontal groove 4, it can move left and right against the upper surface of the diversion plate 1.

[0021] The right end of the drainage plate 1 on the left is fixed with a hinge shaft 6, and the front and rear sides of the left end of the drainage plate 1 on the right are respectively fixed with support plates 7. The hinge shaft 6 passes through the front and rear ends of the support plate 7 and is rotatably connected to the support plate 7.

[0022] A first arc plate 8 with a downward-facing semicircular shape is fixed between the two support plates 7. The first arc plate 8 is coaxial with the hinge shaft and its right end is fixedly connected to the right side drain plate 1. A second arc plate 9 with a downward-facing semicircular shape is fixed to the right end of the left side drain plate 1. The second arc plate 9 is coaxial with the first arc plate 8 and its inner diameter is equal to the outer diameter of the first arc plate 8.

[0023] The upper end of the diversion plate 1 is fixed with baffle plates 10 on the front and rear sides respectively. The baffle plates 10 can prevent materials from falling from the front and rear sides of the diversion plate 1. Each baffle plate 10 has a first groove 11 opened on its inner side along the length of the diversion plate 1. A second groove 12 perpendicular to the first groove 11 is opened at the end of the first groove 11 near the scraper 5. Each scraper 5 has a sliding rod 13 fixed at its front and rear ends respectively. The sliding rod 13 can slide up and down in the second groove 12. When the scraper 5 extends out of the transverse groove 4, the sliding rod 13 can slide left and right along the first groove 11.

[0024] The scraper 5 has a U-shaped rod 14 with its opening facing downwards fixed on its front and rear sides. The two vertical rods of the U-shaped rod 14 are located on the front and rear sides of the baffle plate 10 on the corresponding sides.

[0025] A roller 15 is provided on the upper end face of the opening position of the U-shaped block 3. The inner ends of the two U-shaped blocks 3 on the front side are respectively connected by a bolt 16 through the thread. The bolt 16 passes through the inner end face of the U-shaped block 3 to the opening.

[0026] It is worth mentioning that the scraper 5 is wrapped with a rubber layer on the outside, and the rubber layer can fit tightly with the transverse groove 4, the diversion plate 1 and the baffle plate 10.

[0027] In use, this utility model first requires the construction of two layers of inner and outer concrete support formwork on both sides of the rainwater ditch, such as... Figure 5 As shown, the area between the inner and outer support templates is the sidewall of the rainwater channel. Then, two diversion plates 1 are erected in a V-shape on the two inner support templates from above, so that the opening on the lower side of the U-shaped block 3 is locked at the upper end of the inner support template. At this time, the roller 15 is in contact with the upper surface of the inner support template. The whole device can slide freely back and forth along the inner support template through the roller 15, which is convenient for adjusting the pouring position. After determining the pouring position, the inner support template is tightened by adjusting bolt 16 to fix the position of the front U-shaped block 3, thereby fixing the whole device to the inner template. Then, the concrete pouring pipe is aligned with the middle position of the two diversion plates 1 for pouring. The concrete is evenly discharged from the middle to the left and right sides by the diversion plate 1 until the concrete fills the template at this position. Then, the whole device is released from the limit by rotating the bolt 16 in the opposite direction and the whole device is pushed forward a certain distance. The above operation is repeated to pour the next section. This process can be repeated to achieve rapid pouring of the rainwater channel.

[0028] When concrete remains on the diversion plate 1 and the baffle plate 10 after a long period of pouring, the pouring operation is first suspended. Then, the scraper 5 is pulled upward by manually operating the U-shaped rod 14, so that the scraper 5 is disengaged from the transverse groove 4. At this time, the sliding rod 13 moves upward to the uppermost end along the second sliding groove 12. Then, the U-shaped rod 14 is pulled outward parallel to the diversion plate 1, so that the scraper 5 scrapes the material outward. At this time, the sliding rod 13 moves outward along the first sliding groove 11, which can scrape off the concrete material remaining on the diversion plate 1 and the baffle plate 10. After scraping, the scraper 5 can be reset by moving it in the opposite direction along the first sliding groove 11 and the second sliding groove 12 into the transverse groove 4. This not only blocks the transverse groove 4, but also facilitates the next scraping.

[0029] This invention, by hinged at the ends of two diversion plates 1 and arranged in a V-shape above the sidewall template of the rainwater channel, enables a single concrete pouring pipe to simultaneously pour concrete from both sides, greatly improving pouring efficiency. Furthermore, the two diversion plates 1 can rotate freely around the hinge axis, and the U-shaped block 3 can rotate around the crossbar 2, allowing the device to adapt to rainwater channel pouring of different widths and avoiding assembly errors caused by construction mistakes, thus greatly improving the device's practicality. By setting a scraper 5 on the inner end of each diversion plate 1 and restricting the movement direction of the scraper 5 through the first sliding groove 11 and the second sliding groove 12, the operator can quickly operate the scraper 5 via the U-shaped rod 14 to scrape off residual concrete material on the diversion plates 1 and the baffle plate 10, greatly extending the device's service life and ensuring its cyclic reusability.
