Description

Technical Field

[0001] The utility model relates to the technical field of construction equipment, in particular to a concrete chute device. Background Art

[0002] At present, the concrete pouring methods at the construction site generally include using a pump truck, a ground pump, self-flow, or splicing a chute on site. For some small amounts of concrete, for economic reasons, a chute is mostly made on site for concrete pouring. However, for the on-site spliced chute, the current common method is to set up a framework with steel pipe scaffolds, then use plywood as the base on the framework, add wooden strips on both sides of the plywood with nails, and at the same time tie the plywood to the steel pipe scaffolds with iron wires. This chute is not only heavy and inconvenient to move, but also requires a lot of manpower for splicing, which is not only time-consuming and laborious, but also has a high cost. Content of the Utility Model

[0003] The utility model provides a concrete chute device, which adopts a combined structure, is convenient for quick lap joint installation, and can be quickly recycled and reused to solve the problems in the background art.

[0008] Advantages of this solution:

[0009] This solution invents a concrete chute device. This chute device adopts a combination of corrugated pipes and a support frame body, and the materials used are simple and easily available. The corrugated pipe is supported by the support frame body, and the concrete is conveyed by the corrugated pipe. No additional power system is required.

[0014] The following further describes the present utility model in conjunction with the drawings and embodiments:

[0015] Reference numerals in the embodiment: support frame body 1, corrugated pipe 2, inspection port 2a, diversion port 2b, U-shaped guiding groove 31, support rod 32, connecting hanging rope 33, hanging rope 4, discharge chute 5, arc fixing ring 11, support hollow pipe 12, adjustment hole 12a, adjustment hollow pipe 13, fixing hole 13a, connecting plate 14, support foot 15.

[0016] As Figure 1 、 Figure 2 and Figure 3 shown, the present utility model discloses a concrete chute device, including a support frame body 1 and a corrugated pipe 2. As Figure 1The illustrated embodiment adopts a series combination of four support frames 1 and two corrugated pipes 2 to achieve the ability to extend the concrete chute, thereby realizing the long-distance transportation of concrete. The specific quantity actually used on-site needs to be determined according to the specific construction site.

[0017] This solution takes Figure 2 the illustration as an example to explain the specific structure and usage method of the concrete chute device. The support frame 1 includes three support feet 15 from bottom to top. The three support feet 15 are jointly connected to a connection disk 14, and all three support feet 15 are hinged to the support plate to facilitate the square collection and support angle adjustment of the three support feet 15. Of course, the three support feet 15 are evenly distributed along the disk surface direction of the connection disk 14 to achieve force balance. The three support feet 15 and the connection disk 14 form a tripod, and the support feet 15 can also adopt threaded telescopic rods to achieve the height and stability adjustment of the tripod.

[0018] In this solution, the height adjustment of the support feet 15 is not the only way to adjust the height of the corrugated pipe 2. The support height of the corrugated pipe 2 mainly relies on other structures for adjustment. As Figure 3 shown, a regulating hollow pipe 13 is fixedly connected to the middle of the connection disk. A support hollow pipe 12 is also slidably connected coaxially up and down inside the regulating hollow pipe 13. Fixing holes 13a are formed on the pipe wall of the regulating hollow pipe 13, and regulating holes 12a are formed on the closing flash of the support hollow pipe 12. The fixing holes 13a and the regulating holes 12a cooperate and are axially fixed through connection fixing pins. The relative positions of the regulating hollow pipe 13 and the support hollow pipe 12 are locked by using the connection fixing pins, thereby realizing the adjustment of the height of the support corrugated pipe 2. The top end of the support hollow pipe 12 is fixedly connected with an arc-shaped fixing ring 11, and the inner diameter of the arc-shaped fixing ring 11 is larger than the outer diameter of the corrugated pipe 2. During installation, the corrugated pipe 2 can be directly placed into the arc-shaped fixing ring 11 from top to bottom.

[0019] Currently, concrete is transported by mixer trucks. Specifically in this solution, one end of the corrugated pipe 2 is cut axially to form a diversion port 2b, and an inspection port 2a is formed in the middle of the corrugated pipe 2. Concrete enters the corrugated pipe 2 through the diversion port 2b, and inspections and cleaning can be carried out through the inspection port 2a during the transportation process. Since the overall stiffness of the corrugated pipe 2 may decrease after cutting the diversion port 2b, in order to prevent the diversion port 2b of the corrugated pipe 2 from being damaged too quickly, a hanging rope 4 is further provided at the diversion port 2b of the corrugated pipe 2, and hooks are fixedly connected to both ends of the hanging rope 4. When the corrugated pipe 2 transports concrete, the two hooks of the hanging rope 4 can be hung on the frame of the mixer truck to prevent the diversion port 2b of the corrugated pipe 2 from suffering fatigue damage.

[0020] It should be noted that if the corrugated pipe 2 is to be reused, it is necessary to flush the corrugated pipe 2 before the concrete initial sets after the concrete transportation is completed. However, the discharge end of the corrugated pipe 2 is aligned with the pouring site. If it is directly flushed, the flushing water will erode the concrete at the pouring site. Therefore, this solution also involves a flushing diversion structure.

[0021] As Figure 2 shown, the flushing diversion structure includes a U-shaped diversion groove 31, a support rod 32, and a connecting hanging rope 33. Both ends of the connecting hanging rope 33 are fixedly connected to the middle of the U-shaped diversion groove 31, and one end of the support rod 32 is hinged to the bottom of the U-shaped diversion groove 31. After the concrete pouring is completed, first install this flushing diversion structure. The water flushed out of the corrugated pipe 2 will flow reversely along the U-shaped diversion groove 31 to the outside of the concrete pouring area, thus realizing rapid flushing of the corrugated pipe 2 and not affecting the concrete pouring quality.

[0022] The specific installation method of this solution is relatively simple. The diversion port 2b of the corrugated pipe 2 is aligned with the discharge chute 5 of the mixer truck, and then the other end of the corrugated pipe 2 is aligned with the concrete pouring site. Support the corrugated pipe 2 by setting a number of support frames 1 and make the diversion port 2b of the corrugated pipe 2 higher than the discharge end of the corrugated pipe 2. If there is a pipe blockage or other situation during the concrete transportation process, the corrugated pipe 2 can be quickly dredged by cleaning the inspection port 2a of the corrugated pipe 2. After the concrete pouring is completed, immediately install the flushing diversion structure and clean the corrugated pipe 2.

[0023] The concrete chute device of this solution has a simple structure, is easy to use, has a high reuse rate, high turnover, and short installation and disassembly time, and is very suitable for use in various construction sites.

[0024] The above are only the preferred embodiments of the present invention and are not intended to limit the present invention. Any modifications, equivalent replacements, and improvements made within the spirit and principle of the present invention shall be included in the protection scope of the present invention.
