Description

Technical Field

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

[0002] In municipal road, bridge, and building construction projects, common construction procedures include setting up trench formwork, pouring concrete, and removing formwork for curing. Examples include cable trenches in municipal road projects, concealed trenches under sidewalks in bridge projects, and drainage ditches in building construction projects.

[0003] In existing trench concrete pouring, concrete pump trucks (concrete boom pumps) are mostly used. However, since trench sidewalls are generally designed to be narrow, the width of the upper slab reserved for pouring is limited. When using concrete pump trucks to pour concrete, it is easy for material to fall out of the formwork, resulting in some waste of concrete material. At the same time, trenches are generally designed to be long and narrow, and concrete pump trucks need to be moved with the trench design position. During the movement, drivers and workers to assist in pouring and positioning are required, which consumes too much manpower and mechanical resources.

[0004] In conclusion, existing concrete pump trucks are not suitable for narrow trenches, which can easily lead to a waste of materials and human resources and reduce construction efficiency. Utility Model Content

[0005] To address the aforementioned problems in the prior art, this utility model provides a mobile trench concrete pouring device, which solves the problem that existing concrete pump trucks are inconvenient for pouring concrete in narrow trenches.

[0006] To achieve the above objectives, the technical solution adopted by this utility model is as follows:

[0007] A mobile trench concrete pouring device is provided, comprising two triangular angle steel frames arranged opposite each other. The tops of the two angle steel frames are fixedly connected by a crossbeam. A guide plate for guiding concrete flow into the trench template is fixed between the two opposite sides of the two angle steel frames. Universal wheels are provided on both sides of the bottom of each angle steel frame. The four universal wheels are arranged in pairs front and back. The two pairs of universal wheels are respectively rolled in two guide channels. The two guide channels are respectively fixed on the two inner sides of the trench template.

[0008] The beneficial effects of this solution are as follows: By manually pouring concrete onto the guide plates on both sides of the angle steel frame, the two guide plates direct the concrete into the cavity of the trench formwork. During this pouring process, the triangular structure of the angle steel frame not only provides stable support but also adapts to the narrow space of the trench formwork. The guide plates precisely guide the flow of concrete, reducing material spillage and waste. Furthermore, after a section of the trench formwork is poured, the angle steel frame can be easily moved along the trench formwork using casters and guide channels. The overall structure is lightweight, reducing manpower requirements, improving pouring efficiency, and shortening the construction cycle.

[0009] Furthermore, each angle steel frame includes a bottom angle steel, with both sides of the bottom angle steel fixed to the bottom ends of two side angle steels, and the top ends of the two side angle steels fixed to the crossbeam. The modular structure allows for flexible size adjustment to accommodate different groove widths.

[0010] Furthermore, the vertical edges of the two side angle steels located on opposite sides of the two angle steel frames are far apart from each other. This arrangement of the vertical edges of the two side angle steels on opposite sides facilitates the limiting of the flow guide plate.

[0011] Furthermore, the bottom angle steel is bolted or welded to the side angle steel. Bolted connections facilitate quick on-site assembly / disassembly, adapting to temporary construction needs; welded connections ensure structural strength for long-term use. Two options are provided to enhance the applicability of the device.

[0012] Furthermore, the bottom ends of both angle steel frames are fixedly connected by connecting beams. The connecting beams improve the stability of the device during movement and prevent displacement due to vibration.

[0013] Furthermore, both ends of the crossbeam are fixedly connected to the tops of two uprights, and the bottoms of both uprights are fixed to two bottom angle steels. The uprights form a three-dimensional support frame, distributing the force on the crossbeam and improving its load-bearing capacity.

[0014] Furthermore, the middle section of the crossbeam is fixedly connected to two connecting beams on each side by two supporting steel bars. The supporting steel bars form a triangular reinforcement structure to prevent the middle section of the crossbeam from sagging, while also supporting the drainage plate.

[0015] Furthermore, both guide channels are U-shaped. The U-shaped channels wrap around and limit the casters, preventing derailment. Additionally, U-shaped channels are readily available, reducing manufacturing costs.

[0016] Furthermore, the crossbeams, two uprights, and two connecting beams are all made of square steel. Standardized square steel is easy to procure, reducing manufacturing costs. Attached Figure Description

[0021] The specific embodiments of this utility model are described below to enable those skilled in the art to understand this utility model. However, it should be understood that this utility model is not limited to the scope of the specific embodiments. For those skilled in the art, as long as various changes are within the spirit and scope of this utility model as defined and determined by the appended claims, these changes are obvious. All utility model creations utilizing the concept of this utility model are within the scope of protection.

[0022] In the prior art, due to the narrow and elongated design of the trench formwork 8 and the excessive size of the concrete pump truck, it is inconvenient to position and move the concrete for pouring concrete in the narrow trench formwork 8. This not only results in high operating costs for manpower and equipment but also easily leads to concrete overflow and material waste. In order to overcome the problem that existing equipment is inconvenient for pouring concrete in narrow trenches, this embodiment provides a mobile trench concrete pouring device. Concrete is poured manually into the diversion plates 3 on both sides of the angle steel frame 1. The two diversion plates 3 can guide the concrete into the cavity of the trench formwork 8. During this pouring process, the triangular structure of the angle steel frame 1 not only provides stable support but also adapts to the narrow space of the trench formwork 8. The diversion plates 3 accurately guide the flow of concrete, reduce material overflow and waste, reduce construction costs, and improve construction efficiency.

[0023] refer to Figure 1 A mobile trench concrete pouring device includes two opposing angle steel frames 1, both of which are triangular in structure. The triangular angle steel frames 1 not only provide stable support but also adapt to the narrow space of the trench formwork 8.

[0024] Each angle steel frame 1 includes a bottom angle steel 12, with its two sides fixed to the bottom ends of two side angle steels 11 respectively. The top ends of the two side angle steels 11 are fixed to the crossbeam 2. The modular structure allows for flexible size adjustment to accommodate different trench widths. Furthermore, to facilitate the positioning of the drainage plate 3, the vertical edges of the two side angle steels 11 located on opposite sides of the two angle steel frames 1 are spaced far apart from each other.

[0025] The tops of the two angle steel frames 1 are fixedly connected by a crossbeam 2, and the bottom ends of the two angle steel frames 1 are fixedly connected by a connecting beam 6. The two ends of the crossbeam 2 are fixedly connected to the tops of two uprights 7, and the bottoms of the two uprights 7 are fixed to two bottom angle steels 12. The uprights 7 form a three-dimensional support frame, distributing the force on the crossbeam 2 and improving the load-bearing capacity.

[0026] In this embodiment, the crossbeam 2, the two uprights 7, and the two connecting beams 6 are all made of square steel. Standardized square steel is easy to procure, reducing manufacturing costs. In this embodiment, the fixing methods between the bottom angle steel 12, the side angle steel 11, the crossbeam 2, the two uprights 7, and the two connecting beams 6 include bolt connection or welding. Welding can be single-sided welding, double-sided welding, etc., and bolt connection can use hexagonal bolts or other types of bolts selected according to the chute length and component thickness.

[0027] A guide plate 3 for guiding concrete flow into the trench formwork 8 is fixed between the two opposing sides of the two angle steel frames 1.

[0028] Each angle steel frame 1 is equipped with casters 4 on both sides of its bottom. The four casters 4 are arranged in pairs, one in front of the other. The two pairs of casters 4 are respectively rolled within two guide channels 5, which are fixed to the two inner sides of the trench template 8. To reduce manufacturing costs, both guide channels 5 are U-shaped channels.

[0029] To further reinforce the entire device, refer to Figure 2 and Figure 3 The middle section of the crossbeam 2 is fixedly connected to two connecting beams 6 by two supporting steel bars 21 on each side. The supporting steel bars 21 form a triangular reinforcement structure to prevent the middle section of the crossbeam 2 from sagging, and also to support the diversion plate 3. In this embodiment, the number of supporting steel bars 21 can be adjusted according to the length of the chute. In addition, if the chute length is short, it is not necessary to set supporting steel bars 21, and the connecting beams 6 can also be omitted.

[0030] The method for creating and using this solution is as follows:

[0031] 1. Based on the width of the trench template 8, select the dimensions of the frame and reserve bolt holes on the bottom angle steel 12 and the side angle steel 11;

[0032] 2. Based on the selected dimensions, fix the connecting beam 6 at both ends of the side angle steel 11 by welding. The position of the connecting beam 6 should ensure that its outer side is close to the inner template of the trench.

[0033] 3. Weld uprights 7 to the middle of the bottom angle steel 12, and weld crossbeams 2 to the top of the uprights 7 on both sides, as the supporting structure of the angle steel frame 1;

[0034] 4. Weld one end of each of the four side angle steels 11 to the crossbeam 2, and the other end to the bottom angle steel 12;

[0035] 5. Lay the diversion plate 3 on the side angle steel 11 on both sides. With the construction tools in hand, the workers use hex bolts to fix the diversion plate 3 through the reserved space. Similarly, use hex bolts to fix the caster 4 to the bottom angle steel 12. Lock the direction of the wheels when using.

[0036] 6. Weld a supporting steel bar 21 between the crossbeam 2 and the connecting beam 6 to serve as the supporting structure for the top wooden board and the stable structure for the square steel frame. The number of steel bars can be appropriately set according to the actual required chute length on site.

[0037] 7. When setting up the trench formwork 8, reserve the groove position and fix the guide channel steel 5 according to the actual conditions to form the groove track for the chute to slide.

[0038] 8. Finally, the concrete can be poured manually from the top diversion plate 3. The concrete flows into the precision trench template 8 along the diversion plates 3 on both sides. After this section of the trench is poured, the chute tool can be pushed to the next section of the trench by manual assistance to carry out the next section of trench pouring process.

[0039] Although the specific embodiments of the utility model have been described in detail with reference to the accompanying drawings, this should not be construed as limiting the scope of protection of this patent. Various modifications and variations that can be made by those skilled in the art without inventive effort within the scope described in the claims still fall within the scope of protection of this patent.
