Description

Technical Field

[0001] The present invention relates to the technical field of construction equipment, and specifically relates to a device for collecting scattered concrete during the feeding process of a concrete pump truck. Background Art

[0002] During the construction process of a building project, concrete pouring is a very important and time-consuming process. Currently, ready-mixed concrete is mostly poured into molds such as columns, beams, and roof slabs by pumping. During the pouring process, it is necessary to transfer from one pouring area to another. There may be a gap between the two pouring areas, so the ready-mixed concrete will be scattered during the transfer, resulting in waste. In addition, the two pouring areas may not be adjacent. For example, the concrete for the columns to be poured and the concrete for the beams to be poured may be of different grades. Therefore, during the pouring process, the concrete for pouring the columns cannot be scattered into the molds of the beams. Preventing the ready-mixed concrete from scattering when the discharge port of the pumping truck moves horizontally not only avoids waste but also ensures quality. Therefore, it has become an urgent requirement to design a concrete collection device to prevent the ready-mixed concrete from scattering. Summary of the Invention

[0018] To make the technical solutions and beneficial effects of the present invention clearer, the following further elaborates on the embodiments of the present invention.

[0019] A device for collecting scattered concrete during the feeding process of a concrete pump truck mainly consists of an anti-scattering pipe 10 and an opening / closing baffle 20 inserted in the middle of the anti-scattering pipe 10. The upper end of the anti-scattering pipe 10 is connected to the end of the pump truck delivery pipe, and a clamping mechanism, a lapping mechanism or a hanging mechanism can be provided at the upper end of the anti-scattering pipe 100 to achieve the connection. An insertion joint 11 is provided in the middle of the anti-scattering pipe 10 for inserting or installing the opening / closing baffle 20. The function of the opening / closing baffle 20 is to prevent the ready-mixed concrete from being scattered by blocking the anti-scattering pipe 10, that is, to collect the ready-mixed concrete that is about to be scattered.

[0020] To achieve the insertion and blocking effects, the range of the radian of the insertion joint 11 is set to 180° < d ≤ 270°, where d is the radian of the insertion joint 11. When the radian is less than 180°, the opening / closing baffle 20 cannot be fully inserted into the insertion joint, so it cannot achieve complete blocking, and thus the collection effect of the scattered concrete cannot be achieved. If it is greater than 270°, the strength of the anti-scattering pipe 10 cannot meet the strength requirements, and it is easy to break or bend.

[0021] As Figure 2, Figure 3 As shown in the figure, the outer diameter of the large cut circle at the position of the opening and closing baffle 20 corresponding to the insertion joint 11 is greater than the outer diameter of the anti-scattering pipe 10, and the radius of the corresponding small cut circle is the same as the inner diameter of the anti-scattering pipe 10. At this time, after the opening and closing baffle 20 is inserted, the anti-scattering pipe 10 can be completely blocked.

[0022] In this embodiment, the anti-scattering pipe 10 is made of hot-dip galvanized steel pipe, and the length is set to 1000 mm. In the specific use process, the appropriate length can be selected according to the specific construction conditions, and the material can be selected according to actual needs, such as steel pipe, PVC pipe, etc. The upper end is connected to the hose of the pump truck delivery pipe by means of a clamp. In this embodiment, a 3 / 4 circumference slit is cut in the middle position of the anti-scattering pipe, that is, the radian of the insertion joint 11 is 270°. The width of the insertion joint 11 can be set according to actual needs. In this embodiment, the width of the insertion joint 11 is 3 mm, and the thickness of the opening and closing baffle 20 is 1 mm.

[0023] When the opening and closing baffle 20 is inserted and connected to the insertion joint 11 of the anti-scattering pipe 10, it can be inserted when it needs to be blocked. When it needs to discharge materials, it can be pulled out. At the same time, hanging holes or hooks can be set on the opening and closing baffle 20, and hooks can be set on the anti-scattering pipe 10, and it can be hung on the anti-scattering pipe 10 when it does not need to be blocked.

[0024] When the opening and closing baffle 20 is hinged to the insertion joint 11 of the anti-scattering pipe 10, as Figure 2 shown, the upper part of the opening and closing baffle 20 is provided with a hinged lug 22. The anti-scattering pipe 10 is provided with a hinged hanging ear 12 at the position corresponding to the hinged lug 22. The opening and closing baffle 20 and the anti-scattering pipe 10 are hinged by the hinged lug 22 and the hinged hanging ear 12. When the opening and closing baffle 20 is hinged to the insertion joint 11 of the anti-scattering pipe 10, the hinged lug 22 and the hinged hanging ear 12 need to be arranged close to the edge of the insertion joint 11. In this embodiment, as Figure 1 shown, the hinged lug 22 and the hinged hanging ear 12 are provided with overlapping through holes. The hinged hanging ear 12 is provided with two, and the hinged lug 22 is arranged between the two hinged hanging ears. A T-shaped pin is inserted into the through hole. The T-shaped pin can be removed at any time, and the use and maintenance are more convenient.

[0025] When the opening and closing baffle 20 is hinged to the insertion joint 11 of the anti-scattering pipe 10, in order to facilitate the operation of the opening and closing baffle 20, a handle 21 is provided on the upper part of the opening and closing baffle 20. As shown in the figure, the handle 21 can be in the shape of a strip-shaped grip, or can be set in a ring shape. The ring-shaped handle is directly connected to the opening and closing baffle 20 or connected by a strip-shaped plate. By setting the handle, the opening and closing baffle 20 can be conveniently opened and closed.

[0026] Preferably, the articulated lug 22 is disposed opposite to the handle 21, and in this case, the operation is more labor-saving. To improve safety, the edges of the tube at the lower end of the anti-scattering tube 10 are polished into rounded corners to prevent sharp corners from hurting people.

[0027] In summary, only the preferred embodiments of the present invention are described above, and are not intended to limit the scope of the present invention. Through the above description, relevant staff can make various changes and modifications without departing from the technical idea of the present invention. The technical scope of the present invention is not limited to the content of the specification. All equivalent changes and modifications in terms of the shape, structure, features and spirit described in the claims of the present invention shall be included within the scope of the claims of the present invention.
