Description

Technical Field

[0001] This utility model belongs to the technical field of concrete conveying equipment, and specifically relates to a concrete feeding device. Background Technology

[0002] With the continuous development of water conservancy projects, the volume and height of dams have gradually increased, and the amount of concrete poured has also increased significantly. The amount of concrete poured for some large dams can reach millions of cubic meters or even more.

[0003] Traditional concrete transportation and pouring methods are insufficient to meet the pouring requirements. Using concrete pump trucks requires frequent loading, unloading, and waiting during transportation, resulting in slow speeds that cannot meet the requirements of continuous and rapid dam pouring. Furthermore, during transportation, concrete is prone to segregation due to factors such as bumps and vibrations, leading to reduced uniformity and strength, which in turn affects the quality of dam pouring.

[0004] Meanwhile, conventional pouring methods require significant manpower and material resources during construction, resulting in complex construction organization and management difficulties. Due to low transportation efficiency, more transportation equipment and personnel are needed to transport the concrete, which not only increases construction costs but may also lead to chaos on the construction site, affecting construction progress and quality.

Detailed Implementation

[0032] To facilitate understanding of this application, a more complete description will be provided below with reference to the accompanying drawings, which illustrate embodiments of the present application. However, the present application can be implemented in many different forms and is not limited to the embodiments described herein. Rather, these embodiments are provided so that the disclosure of this application will be thorough and complete.

[0033] like Figure 1 and Figure 2 As shown, a concrete feeding device includes a feeding line 1, a tower crane 2, and a belt conveyor 4 arranged in sequence. One end of the feeding line 1 is located below the concrete supply point to receive the supplied concrete, and the other end is used to transport concrete to the rear end. The tower crane 2 includes a tower column 21 and a horizontal lifting arm 22. A climbing frame 3 is attached to the tower column 21 and can be raised and lowered along the tower column 21. The discharge end of the feeding line 1 is hinged to the climbing frame 3. The feeding line 1 and the belt conveyor 4 are respectively arranged on both sides of the tower crane 2. The concrete delivered by the feeding line 1 to the tower crane 2 is transferred to the belt conveyor 4 and precisely poured to the pouring point by the belt conveyor 4.

[0034] One end of the belt conveyor 4 is rotatably connected to the climbing frame 3 and can rotate around the climbing frame 3, while the other end is used to transport concrete to the pouring point. The belt conveyor 4 can adapt to the rise and fall of the climbing frame 3. The position of the belt conveyor 4 near the pouring end is connected to the horizontal lifting arm 22, thereby achieving stable installation of the belt conveyor 4.

[0035] In the first embodiment, the belt conveyor 4 is connected to the horizontal lifting arm 22. Specifically, a lifting hook 23 is slidably mounted on the horizontal lifting arm 22. The end of the lifting hook 23 away from the horizontal lifting arm 22 is connected to the belt conveyor 4. The tilt of the belt conveyor 4 can be adjusted by adjusting the height of the lifting hook 23. In the second embodiment, a tie cable 24 is also provided between the climbing frame 3 and the belt conveyor 4. A fixed pulley is provided on the climbing frame 3, and a winding device 5 for controlling the winding and unwinding of the tie cable 24 is provided below the fixed pulley. The winding device 5 can be a winch. One end of the tie cable 24 is connected to the belt conveyor 4, and the other end passes around the fixed pulley and is connected to the winding device 5. The tie cable 24 and the lifting hook 23 can stably tie the belt conveyor 4, thereby enabling the belt conveyor 4 to transport concrete more stably. In addition, by controlling the length of the tie cable 24 and the height of the lifting hook 23, the tilt of the belt conveyor 4 can be adjusted, thereby flexibly controlling the concrete pouring of the belt conveyor 4.

[0036] In the third embodiment, the conveyor belt 4 specifically includes an inner placing conveyor belt 41 and an outer placing conveyor belt 42. One end of the inner placing conveyor belt 41 is rotatably connected to the climbing frame 3 to receive concrete transmitted by the supply line 1, and the other end is rotatably connected to the outer placing conveyor belt 42 to deliver concrete to the outer placing conveyor belt 42. A lifting hook 23 on the horizontal lifting arm 22 is connected to the outer placing conveyor belt 42 to achieve the connection of the free end of the outer placing conveyor belt 42. A connecting cable 24 is provided between the climbing frame 3 and the inner placing conveyor belt 41. One end of the connecting cable 24 is connected to the climbing frame 3, and the other end is connected to the side of the inner placing conveyor belt 41 near the outer placing conveyor belt 42. By setting the inner placing conveyor belt 41 and the outer placing conveyor belt 42, two sections of conveyor belt 4 are spliced ​​together, which can increase the length of the conveyor belt 4, reduce the bending moment force borne by the weight of the conveyor belt 4 in the middle, and at the same time realize flexible pouring under various working conditions.

[0037] Furthermore, both the inner fabric conveyor belt 41 and the outer fabric conveyor belt 42 include a truss frame 44. The truss frame 44 is a truss structure, and a reinforcing fixing plate 45 is provided on the side of the truss frame 44 facing the ground. The reinforcing fixing plate 45 is located at the connection position between the inner fabric conveyor belt 41 and the tie cable 24, and at the connection position between the outer fabric conveyor belt 42 and the lifting hook 23. By providing the reinforcing fixing plate 45, the strength of the connection of the truss frame 44 can be enhanced, the possibility of deformation of the truss frame 44 due to concentrated tension can be reduced, and the structural stability of the inner fabric conveyor belt 41 and the outer fabric conveyor belt 42 can be ensured during use.

[0038] Based on the first, second, or third embodiment, the belt conveyor 4 further includes a transfer belt conveyor 43, which is installed inside the climbing frame 3 and serves as a transfer and transportation mechanism for concrete. The feed line 1 is connected to the top of the climbing frame 3, and the belt conveyor 4 is connected to the area near the bottom of the climbing frame 3. The transfer belt conveyor 43 receives the concrete conveyed by the feed line 1 and transports it to the belt conveyor 4. The transfer belt conveyor 43 eliminates the need for concrete to be directly poured from the discharge end of the feed line 1 onto the belt conveyor 4, reducing the risk of concrete segregation due to long-distance falls. It also mitigates the impact of falling concrete on the belt conveyor 4, thereby improving the quality of concrete transportation and extending the service life of the belt conveyor 4.

[0039] The feeding line 1 includes multiple conveying sections 12 and several support seats 11. Each conveying section 12 has at least two support seats 11 underneath, which support the conveying section 12 and adjust its installation height. When concrete is transported through the feeding line 1, the concrete passes through each conveying section 12 in sequence to reach the tower crane 2.

[0040] The support base 11 can be a column or a structural pier, and the height of each support base 11 can be different. For sections with low support height and no need for height adjustment, structural piers can be directly cast to support the material conveying section 12; for sections with high support height or height climbing requirements, the support base 11 is set as a column, and the column is a steel structure.

[0041] Among them, some support bases 11 are also equipped with climbing platforms 13 that can be raised and lowered along the support base 11. Usually, the climbing platform 13 is set on the column, and the material conveying section 12 is rotatably connected to the climbing platform 13. Thus, by adjusting the height of the climbing platform 13, the height of the material conveying section 12 can be adjusted. The angle between the material conveying section 12 and the climbing platform 13 can be adjusted adaptively, so that the height position of the material conveying section 12 can be adjusted according to the pouring height of the dam.

[0042] The above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
