Description

Technical Field

[0001] This utility model relates to the field of concrete chute technology, specifically a telescopic assembled concrete chute. Background Technology

[0002] With the development of wind resources in plains reaching saturation, wind power construction in my country is gradually shifting to mountainous and high-altitude areas. Mountain wind farms are characterized by high wind speeds and strong turbulence, which are conducive to power generation. However, the terrain is complex, material transportation is difficult, and construction conditions are harsh. Currently, concrete chutes are commonly used as connections to facilitate the transportation of concrete to the required location in complex mountainous terrain.

[0003] When using existing concrete chutes, conventional chutes are large in size, making transportation and installation inconvenient. Moreover, the length of conventional chutes is not easy to match and adjust according to the environment. When concrete mixer trucks are restricted by roads, chutes sometimes cannot adapt to complex mountainous terrain. Large-volume continuous concrete construction is highly dependent on pump trucks. Utility Model Content

[0004] The purpose of this utility model is to provide a telescopic assembled concrete chute to solve the problems mentioned in the background art, such as the large volume of conventional concrete chutes, which makes transportation and installation inconvenient, the difficulty in adjusting the length of conventional chutes to match the environment, the difficulty of adapting chutes to complex mountainous terrain when concrete mixer trucks are restricted by roads, and the high dependence of large-volume continuous concrete construction on pump trucks.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a retractable assembled concrete chute, including a transmission chute, which is composed of multiple single chutes spliced ​​together. Each single chute is a cylindrical structure with one end diameter larger than the other end diameter. The connecting ends of adjacent single chutes are matched. A chute assembly and fixing assembly is installed between two adjacent single chutes to fix them relatively. The chute assembly and fixing assembly includes a limiting member, which is fixed to the single chute. The limiting members of adjacent single chutes are connected. A vibrator is installed on the periphery of the single chute located in the middle of the transmission chute.

[0006] Preferably, in the direction from the ash inlet to the ash outlet of the conveying chute, the diameter of each single chute of the conveying chute increases sequentially and is fitted around the periphery of the previous single chute.

[0007] Preferably, the chute assembly and fixing assembly further includes side connectors and support rods. The two sets of limiting members are combined and installed on the periphery of the single chute. The side connectors are provided on the side of the limiting members away from the single chute. The side connectors on the two sets of limiting members of the chute assembly and fixing assembly connecting adjacent single chutes are connected by support rods.

[0008] Preferably, a reference positioning mark line is provided on the surface of the single chute, and two sets of combined limiting members are installed in the positioning mark line area of ​​the single chute, where the outer diameter of the single chute matches the inner diameter of the limiting member.

[0009] Preferably, the side connectors on one set of limiting members of the same chute assembly and fixing component are provided with grooves, and the side connectors on the other set of limiting members are provided with through holes. One end of the support rod is threaded to the side connector with the through hole, and the other end corresponds to the groove position of the side connector.

[0010] Preferably, the limiting member includes a semi-ring, a washer, and a connecting protrusion. The semi-rings of the two sets of limiting members are combined and fitted around the periphery of the single chute to form a complete ring. The semi-rings of the two sets of limiting members are connected to each other by screws through the connecting protrusions set above and below. A washer is provided on the side of the semi-ring close to the surface of the single chute.

[0011] Preferably, the single chute located at the ash outlet end of the conveying chute is connected to an ash discharge direction adjustment component. The ash discharge direction adjustment component includes a support base, an ash discharge chute, and a rubber sleeve. The ash outlet of the single chute is connected to the rubber sleeve, and the ash outlet of the rubber sleeve is connected to the ash discharge chute. The ash discharge chute is mounted on a rotatable support base.

[0012] Compared with the prior art, the beneficial effects of this utility model are:

[0013] 1. This utility model, through the setting of single chutes, allows for an adjustable number of spliced ​​single chutes, thereby changing the actual length of the installed transfer chute. Connected between the concrete mixer truck and the construction site, it can adapt to complex mountainous terrain conditions, is not easily restricted by roads, and effectively solves the problem of high dependence on pump trucks in continuous construction of large volumes of concrete. In the non-use state, each single chute of the transfer chute retracts, and the single chutes can be embedded together from the inside to the outside in order of increasing diameter. The retractable transfer chute facilitates transportation and storage.

[0014] 2. This utility model, through the setting of the chute assembly and fixing component, ensures that since both sets of limiting parts of the same chute assembly and fixing component are fixed to their respective single chutes, after the support rods are adjusted, the two single chutes can always be connected in this state, keeping the overlapping parts of the two single chutes completely in contact. During construction, adjacent single chutes are connected in this way, which can reduce the influence of the concrete flow direction on the single chute, keep the sections of the single chute from moving easily, keep the overall length of the transmission chute unchanged, make the concrete pass through it more smoothly, and reduce the amount of concrete remaining in the gap between the two single chutes.

[0023] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0024] One embodiment provided by this utility model: as follows Figure 1 As shown, a retractable assembled concrete chute includes a conveying chute 1, a chute assembly and fixing assembly 2, and an ash discharge direction adjustment assembly 3.

[0025] like Figure 1 and Figure 2As shown, the transfer chute 1 is composed of multiple individual chutes 11 spliced ​​together. Each individual chute 11 is a cylindrical structure with one end diameter larger than the other. The connecting ends of adjacent individual chutes 11 are matched. Following the direction from the ash inlet to the ash outlet of the transfer chute 1, the diameter of each individual chute 11 of the transfer chute 1 increases sequentially and fits around the periphery of the preceding individual chute 11. The number of individual chutes 11 spliced ​​together is adjustable, thereby changing the actual length of the completed transfer chute 1. Connected between the concrete mixer truck and the construction site, it can adapt to complex mountainous terrain conditions, is not easily restricted by roads, and effectively solves the problem of high dependence on pump trucks in continuous large-volume concrete construction. In the non-use state, each individual chute 11 of the transfer chute 1 retracts, and the individual chutes 11 can be fitted together sequentially from the innermost to the outermost part, from the smallest to the largest diameter. The retractable transfer chute 1 facilitates transportation and storage.

[0026] like Figure 3 As shown, vibrators 4 are installed around the periphery of a single chute 11 located in the middle of the conveying chute 1. The vibrators 4 are connected to the single chute 11 by connecting straps 41. The number of vibrators 4 can be selected according to the length of the conveying chute 1. At the position near the middle of the conveying chute 1, the vibration effect generated by the vibrators 4 on the conveying chute 1 can reduce aggregate segregation during long-distance concrete conveying.

[0027] like Figure 4 As shown, a chute assembly and fixing component 2 is installed between two adjacent single chutes 11 to fix the two single chutes 11 relative to each other. The chute assembly and fixing component 2 includes a limiting member 21, a side connecting member 22, and a support rod member 23.

[0028] like Figure 5 and Figure 6 As shown, when the limiting member 21 is fixed to the single chute 11, two sets of limiting members 21 are combined and connected to be installed on the periphery of the single chute 11. The limiting member 21 includes a semi-ring 211, a gasket 212, and a connecting protrusion 213. The semi-rings 211 of the two sets of limiting members 21 are combined and fitted around the periphery of the single chute 11 to form a complete ring. The semi-rings 211 of the two sets of limiting members 21 are connected to each other by screws through the connecting protrusions 213 set above and below. A gasket 212 is provided on the side of the semi-ring 211 closest to the surface of the single chute 11. The gasket 212 increases the contact area between the limiting member 21 and the single chute 11, as well as the connection method between the two sets of semi-rings 211, improving the stability of the fixed connection between the limiting member 21 and the single chute 11, and making it less likely that the limiting member 21 will slide onto the side with the smaller diameter on the surface of the single chute 11 during construction.

[0029] like Figure 4 , Figure 5 and Figure 6As shown, a side connector 22 is provided on the side of the limiting member 21 away from the single chute 11. The side connectors 22 on the two sets of limiting members 21 that connect adjacent single chute 11 are connected by a support rod 23. The side connectors 22 on one set of limiting members 21 of the same chute assembly and fixing assembly 2 are provided with a groove 221, and the side connectors 22 on the other set of limiting members 21 are provided with a through hole 222. One end of the support rod 23 is threaded to the side connector 22 with the through hole 222, and the other end corresponds to the groove 221 of the side connector 22. Since both sets of limiting members 21 of the same chute assembly and fixing component 2 are fixed to their respective single chute 11, adjusting the support rod 23 can change the distance between the side connecting members 22 of the two sets of limiting members 21. During the installation of the single chute 11, the length of the support rod 23 left between the side connecting members 22 of the two sets of limiting members 21 is increased, so that the overlapping part between the two single chute 11 is reduced. When the overlapping part of the two single chute 11 is completely fitted, the adjustment of the support rod 23 is stopped. After adjustment, one end of the support rod 23 is restricted at the groove 221, so that the distance between the two sets of limiting members 21 remains unchanged. In addition, the limiting members 21 are fixedly connected to the single chute 11, so that the two single chute 11 can always maintain the connection state at this time, and keep the overlapping parts of the two single chute 11 completely in contact. During construction, adjacent single chute 11 are connected in this way, which can reduce the influence of the concrete flow direction on the single chute 11, keep the sections of the single chute 11 from moving, keep the overall length of the transmission chute 1 unchanged, make the concrete pass through it more smoothly, and reduce the amount of concrete remaining in the gap between the two single chute 11.

[0030] The side connector 22 is connected to the limiting member 21 at a slightly inclined angle. The distribution of the through hole 222 and the groove 221 of the side connector 22 and the distribution direction of the support rod 23 are parallel to the inclined direction of the transmission chute 1, thereby ensuring the normal adjustment of the support rod 23 between the small-diameter single chute 11 and the large-diameter single chute 11.

[0031] The side connectors 22 are symmetrically arranged on the left and right sides of the two connected single chutes 11, and the support rods 23 are also arranged corresponding to the side connectors 22 on the corresponding sides. The symmetrical arrangement makes the connection between the two single chutes 11 more stable and less prone to movement.

[0032] like Figure 1 and Figure 4As shown, to ensure that the limiting component 21 matches the corresponding single chute 11 and is installed stably, the specifications of the limiting component 21 installed on each single chute 11 are different. Since the outer diameter of the single chute 11 varies at different positions, reference positioning marks 111 are set on the surface of the single chute 11. Two sets of combined limiting components 21 are installed in the area of ​​the positioning marks 111 on the single chute 11, where the outer diameter of the single chute 11 matches the inner diameter of the limiting component 21. This guides the installation position of the limiting component 21 to avoid deviations. The positioning marks 111 are evenly distributed at both ends. Each single chute 11 can serve as either the end or the middle of the transfer chute 1.

[0033] like Figure 5 and Figure 6 As shown, the connecting protrusion 213 above the semi-ring 211 has a hole for connecting the semi-rings 211 together. The connecting protrusion 213 above the semi-ring 211 has two holes, one for connecting the semi-rings 211 together and the other for connecting to the mountain below. The concrete increases gravity during transportation in the conveying chute 1. The mountain supports the conveying chute 1, improves the stability of the conveying chute 1, makes it less prone to deformation, and maintains a good transportation slope.

[0034] like Figure 7 As shown, a single chute 11 located at the ash outlet end of the conveying chute 1 is connected to an ash discharge direction adjustment assembly 3. The ash discharge direction adjustment assembly 3 includes a support base 31, a motor 32, an ash discharge chute 33, and a rubber sleeve 34. The ash outlet of the single chute 11 is connected to the rubber sleeve 34, which is fitted around the end of the single chute 11 by an elastic ring 341. The ash outlet of the rubber sleeve 34 is connected to the inner side of the ash discharge chute 33 to prevent ash from getting stuck. The ash discharge chute 33 is mounted on a rotatable support base 31. The body of the drive motor 32 is fixed to the ground, and its output end is connected to the support base 31. The support base 31 has components that can adjust and fix the ash discharge chute 33, ensuring that the ash discharge chute 33 can rotate stably with the drive of the motor 32. When concrete is transported from the inlet of the conveying chute 1 to the outlet, it then enters the discharge chute 33 through the rubber sleeve 34. The rubber sleeve 34 is made of flexible material. At the same time as the concrete is discharged, the direction of the discharge end of the discharge chute 33 is driven by the motor 32, which can flexibly control the concrete to be poured at the required construction position. At the same time, the discharge chute 33 and the conveying chute 1 can have any angle in the vertical direction, which can adapt to the conveying chute 1 with different inclinations.

[0035] The above are merely embodiments of this utility model, and common knowledge regarding specific structures and characteristics in the solutions has not been described in detail here. It will be apparent to those skilled in the art that this utility model is not limited to the details of the above exemplary embodiments, and that it can be implemented in other specific forms without departing from the spirit or essential characteristics of this utility model. Therefore, the embodiments should be considered exemplary and non-limiting in all respects, and the scope of this utility model is defined by the appended claims rather than the foregoing description. Therefore, it is intended that all variations falling within the meaning and scope of equivalents of the claims be included within this utility model. No reference numerals in the claims should be construed as limiting the scope of the claims.
