Description

Technical Field

[0001] The utility model relates to the technical field of tunnel concrete pouring equipment, in particular to a concrete buffer conveying device and system. Background Technique

[0002] At present, for the existing tunnel lining concrete pouring construction, its characteristics are deep tunnel burial depth, narrow space inside the tunnel, extra-long tunnels, etc. For concrete pouring, track transportation and trackless transportation are mostly used. Trackless transportation has high costs, large capital investment, and slow construction efficiency; track transportation is affected by the narrow space inside the tunnel. The rail-type concrete tank trucks need to pour back and forth, consuming a long time, with high labor costs and extremely low concrete transportation efficiency; using the method of setting up a chute well on the ground and discharging concrete through a chute pipe can realize the simultaneous transportation of concrete on the ground and underground, saving the concrete transportation time, not being affected by the narrow space inside the tunnel, and reducing the waiting time of concrete in the tank, improving the quality of concrete. However, most tunnel projects are underground with a large burial depth. When the concrete is discharged through the chute pipe, the falling speed is fast and the impact force is large, which may damage the concrete transportation equipment. To solve this problem, a buffer device for vertical concrete chute feeding disclosed in the Chinese patent document with the publication number CN218061491U reduces the speed of the concrete material flowing out of the pipe and the impact force of the concrete aggregate coming out of the pipe by setting a buffer on the inner wall of the chute pipe and setting a spiral deceleration pipe to change the flow direction of the concrete material multiple times, thereby reducing the splashing of the aggregate and reducing the construction risk of the construction personnel on the bin surface. However, the buffer device for vertical concrete chute feeding has the following deficiencies:

[0003] 1) The buffer conveying unit composed of a chute pipe and a spiral deceleration pipe has a complex structure and high cost;

[0004] 2) The space inside the chute pipe is limited, and it is not convenient to set a buffer;

[0005] 3) The buffer conveying unit composed of a chute pipe and a spiral deceleration pipe only serves as a buffer deceleration before concrete transportation, is difficult to extend, and has a poor buffer effect;

[0006] 4) Due to the complexity of the terrain and geology, there are often large differences in the depths of the chute wells at different locations above the same tunnel. A chute pipe can usually only be applicable to the concrete transportation work of a chute well with a specific depth, which limits its applicability. Content of the Utility Model

[0030] Embodiment 1:

[0031] Figure 1 and Figure 2 Fig. shows an embodiment of the concrete buffer conveying device of this embodiment. The concrete buffer conveying device of this embodiment includes a conveying unit 1. The conveying unit 1 includes a first pipe body 11 and a second pipe body 12. A first notch 111 is provided on the side wall at the bottom end of the first pipe body 11, and a second notch 121 is provided on the side wall at the top end of the second pipe body 12. The first notch 111 and the second notch 121 are aligned and communicated. Side sealing plates 13 are respectively provided between the two sides of the first notch 111 and the second notch 121. Sealing plates 14 are respectively provided at the bottom end of the first pipe body 11 and the top end of the second pipe body 12. The interiors of the first pipe body 11 and the second pipe body 12 are communicated to form a conveying channel 15 with one end for inlet and the other end for outlet. An inclined guiding assembly 2 is provided inside the bottom end of the first pipe body 11 for receiving the concrete falling from above and guiding the concrete into the second pipe body 12.

[0032] In the first aspect, this concrete buffer conveying device includes a conveying unit 1, which is mainly composed of a first pipe body 11 and a second pipe body 12. It has a simple structure and low manufacturing cost. In the second aspect, during the assembly process of the conveying unit 1, a first notch 111 can be opened on the bottom side wall of the first pipe body 11 and a second notch 121 can be opened on the top side wall of the second pipe body 12. Then, the inclined guiding component 2 can be installed inside the bottom end of the first pipe body 11. Next, the bottom end of the first pipe body 11 and the top end of the second pipe body 12 are butted so that the first notch 111 and the second notch 121 are aligned and communicated. Finally, both sides of the first notch 111 and the second notch 121 are connected by side sealing plates 13 respectively, and the bottom end of the first pipe body 11 and the top end of the second pipe body 12 are sealed by a sealing plate 14, so that the interiors of the first pipe body 11 and the second pipe body 12 are communicated to form a conveying channel 15 with one end for inlet and the other end for outlet. That is, the top port of the first pipe body 11 is the inlet of the conveying channel 15, and the bottom port of the second pipe body 12 is the outlet of the conveying channel 15. Compared with the prior art, after opening the notches, installing the inclined guiding component 2 is more convenient as it reduces the limitation of the space inside the chute. In the third aspect, the conveying unit 1 is convenient for lengthening and extending, improving the buffering effect and adaptability.

[0033] Further, in this embodiment, the inclined guiding component 2 includes a buffer plate 21, and the buffer plate 21 is inclined and arranged inside the first pipe body 11. The buffer plate 21 is used to receive the concrete falling from above and guide the concrete into the second pipe body 12. It can guide the concrete from the first pipe body 11 to the second pipe body 12, and at the same time reduce the impact force and speed of the concrete entering the second pipe body 12. It has a simple structure and is easy to manufacture.

[0034] Further, in this embodiment, the inclined guiding component 2 further includes an elastic support member 3. The elastic support member 3 is arranged on the sealing plate 14 at the bottom end of the first pipe body 11, and the buffer plate 21 is supported on the elastic support member 3. When the concrete falls onto the buffer plate 21, the buffer plate 21 undergoes a certain displacement, causing the elastic support member 3 to be compressed, thereby dissipating part of the energy generated by the falling of the concrete, reducing the impact force when the concrete is discharged, and being beneficial to extending the service life of the buffer plate 21. Preferably, the elastic support member 3 is a spring. The spring has a simple structure and reliable use. Of course, in other embodiments, the elastic support member 3 can also be components such as rubber pads, which will not be elaborated here.

[0035] Furthermore, in this embodiment, the top of the buffer plate 21 is hinged to the inner wall of the first tube body 11. When concrete falls onto the buffer plate 21, the buffer plate 21 undergoes a certain rotational displacement to compress the elastic support member 3. The hinged manner not only meets the requirement that the buffer plate 21 rotates downward under the impact of concrete, but also enables the buffer plate 21 to only swing up and down without causing horizontal shaking, thereby preventing the buffer plate 21 from colliding with the inner wall of the tube body. Of course, in other embodiments, the buffer plate 21 can be fixedly connected to the elastic support member 3 and hinged to the inner wall of the first tube body 11, so that the buffer plate 21 is prone to horizontal shaking.

[0036] Furthermore, in this embodiment, the first tube body 11 and the second tube body 12 are both straight.

[0037] Furthermore, in this embodiment, the central axis of the first tube body 11 is parallel to the central axis of the second tube body 12, which is convenient for alignment and assembly.

[0038] Furthermore, in this embodiment, the top end of the first tube body 11 and the bottom end of the second tube body 12 are respectively provided with a butt flange 4, which is convenient for splicing and lengthening.

[0039] Furthermore, in this embodiment, the first tube body 11 and the second tube body 12 are both steel tubes.

[0040] Embodiment 2:

[0041] Figure 3 An embodiment of the concrete buffer conveying system of this embodiment is shown. The concrete buffer conveying system of this embodiment includes the concrete buffer conveying device of the first embodiment. A plurality of conveying units 1 are provided, and each conveying unit 1 can be detachably connected to each other in sequence up and down.

[0042] Each conveying unit 1 can be disassembled and connected in turn up and down. According to the depth of the chute, a reasonable number of conveying units 1 can be flexibly selected to be connected together to carry out the transportation of concrete. It has good flexibility and can be applied to chutes of different depths, saving manufacturing costs.

[0043] The concrete buffer conveying system comprises a concrete buffer conveying device and has all the advantages of the concrete buffer conveying device.
