Abstract
Description
Technical Field
[0001] This utility model belongs to the technical field of concrete conveying equipment, and specifically relates to a support column for a material supply line. Background Technology
[0002] The dam construction involves a large volume of concrete pouring, and traditional concrete pump trucks are insufficient to meet the pouring efficiency requirements. Currently, a construction solution using a tower crane for concrete transportation exists. A tower crane typically consists of a concrete conveyor line and a tower crane. The concrete conveyor line transports concrete over a long distance from the concrete supply point to the tower crane. The tower crane is equipped with a placing conveyor belt, which then transfers the concrete from the conveyor line to the placing conveyor belt for precise delivery to the pouring point.
[0003] The concrete conveyor line needs to stably support the continuous flow of concrete above. In addition, as the height of the dam increases, the concrete conveyor line also needs to be continuously raised. Therefore, a support column for the concrete conveyor line is needed. The support column can not only stably support the concrete conveyor line above, but also achieve height elevation to meet the long-term support requirements of the concrete conveyor line throughout the entire dam pouring process. Utility Model Content
[0004] This utility model provides a support column for a material supply line to solve the problem of stable support for concrete conveying lines.
[0005] To solve the above-mentioned technical problems, the technical solution adopted by this utility model is as follows:
[0006] A material supply line support column includes a column body, which may include a base section, a standard section, and a climbing section, or may include only a base section and a standard section.
[0007] The base section is used to connect to the concrete foundation; the standard section is provided with one or more sections for connecting to the base section; the climbing section includes one or more sections, the climbing section is located on the side of the standard section away from the base section, and a climbing platform capable of climbing along the climbing section is installed on the climbing section.
[0008] Furthermore, the sidewalls of the climbing section are symmetrically formed with two sets of climbing channels, and the climbing platform is connected to the climbing channels and climbs along the climbing channels.
[0009] Furthermore, the climbing channel includes two parallel and spaced climbing lugs, with a hollow connecting crossbar between the two climbing lugs.
[0010] Alternatively, the climbing channel may include a channel steel, the end face of which is welded to the side wall of the climbing section, and the connecting crossbar passes through and is fixed to the channel steel.
[0011] Furthermore, some of the standard sections include a reduced diameter section for connecting the climbing section and the standard section, and the diameter of the climbing section is not greater than the diameter of the standard section.
[0012] Furthermore, adjacent climbing sections are connected by flanges and high-strength bolts;

[0014] Adjacent standard sections are fixed by welding or connected by flanges and high-strength bolts;
[0015] The standard section and the base section are fixed by welding or connected by flanges and high-strength bolts.
[0016] Furthermore, the base section, the climbing section, and the standard section are all cylindrical;
[0017] The base section and the standard section are welded and fixed to one side of the inner or outer wall with a number of limiting keys at intervals, and the limiting keys extend out of the end faces of the base section and the standard section.
[0018] Furthermore, the limiting key extends from the sidewall of the end face of the base section and the standard section to form a guide surface.
[0019] Furthermore, the column also includes a non-standard section, which is disposed at the top of the column, and the structure of the non-standard section is consistent with the structure of the standard section or the climbing section.
[0020] Furthermore, a mounting expansion plate is provided on the side of the base section away from the standard section, and a plurality of shear keys are arranged around the mounting expansion plate and the side wall of the base section.

[0022] The present invention can achieve the following beneficial effects:
[0023] 1. The column is divided into multiple segments, which can gradually increase the height of the column as the dam is poured, thereby realizing the concrete supply throughout the entire life cycle of the dam pouring; at the same time, standard sections and climbing sections are set up, and the climbing sections realize the climbing platform to climb, thereby realizing the lifting of the concrete conveying line; the foundation section is designed to realize the stable connection between the column and the bottom foundation.
[0024] 2. The reduced diameter section can connect climbing sections and standard sections of different diameters, thereby reducing the diameter of the upper part of the column to reduce the weight of the column and allowing the diameter of each section of the column to be adjusted according to different load-bearing requirements.

[0035] 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.
[0036] Example 1
[0037] like Figure 1 and Figure 2 As shown, a material supply line support column includes a column body 1, which comprises a base section 11 and one or more standard sections 12 arranged sequentially from bottom to top. The base section 11 is used to connect to a concrete foundation; the standard sections 12 are connected to the top of the base section 11, and the top of one or more base sections 11 is used to support the concrete conveying line. Dividing the column body 1 into multiple sections facilitates the transportation of the support column, and the required support column can be assembled on site.
[0038] Both the base section 11 and the standard section 12 are cylindrical steel structures. The base section 11 and the standard section 12 are fixed together by welding or high-strength bolts. Adjacent standard sections 12 are fixed together by welding or by flanges and high-strength bolts. If welding is used for fixing, the standard section 12 cannot be removed later; if flanges and high-strength bolts are used for connection, the standard section 12 can be removed and reused later.
[0039] As the height of the support columns gradually increases during the dam's construction, and the anchoring points are only between foundation section 11 and the ground, the swaying force at the top of the support columns increases with their height. Therefore, as the support columns grow taller, concrete piers of a certain height are appropriately poured at the base, embedding the lower part of the support column within these piers, thus discarding the corresponding standard section 12 to ensure structural stability. Since the lower section of the support column, embedded in the concrete pier, cannot be recycled, it is fixed by welding, resulting in a faster, more convenient, and more economical installation.
[0040] For different support columns with varying load-bearing or height requirements, such as some support columns that do not need to be raised later but bear a large load, flanges and high-strength bolts are used to connect the standard sections 12 of the support column to facilitate disassembly and reuse later, while also increasing the connection strength.
[0041] In addition, the foundation section 11 is connected to the foundation base 4 formed by the pouring below. Multiple connecting anchor rods 41 are pre-embedded in the foundation base 4. One end of the connecting anchor rod 41 is anchored into the foundation base 4 and the underlying stratum, and the other end passes through the foundation base 4. An installation expansion plate 111 is provided on the side of the foundation section 11 away from the standard section 12. Several shear keys 112 are arranged around the installation expansion plate 111 and the side wall of the foundation section 11. The design of multiple shear keys 112 can increase the bending moment resistance of the bottom of the supporting column. Multiple through holes are opened on the installation expansion plate 111 corresponding to the multiple connecting anchor rods 41. When installing the foundation base 4, after passing the multiple connecting anchor rods 41 through the corresponding through holes, the high-strength nut is turned onto the connecting anchor rod 41 until it is tightly against the surface of the installation expansion plate 111, and the installation of the foundation base 4 is completed.
[0042] Example 2
[0043] Example 2 is based on Example 1, such as... Figure 3 and Figure 4 As shown, a climbing section 13 is also provided. The climbing section 13 is located on the side of the standard section 12 away from the base section 11. Depending on the total height requirement of the column, the climbing section 13 is provided with one or more sections. A climbing platform 2 that can climb along the climbing section 13 is installed on the climbing section 13. The concrete conveying line is lifted within the elevation range of one climbing section 13 by climbing the climbing platform 2.
[0044] Specifically, the sidewalls of the climbing section 13 are symmetrically formed with two sets of climbing channels. These channels support the climbing platform 2 and allow it to climb along them. In one embodiment, the climbing channel includes two parallel, spaced-apart climbing lugs 131. A connecting crossbar is spaced between the two lugs 131. This connecting crossbar provides a passage for workers to climb along the supporting column and also strengthens the overall strength of the two lugs 131, thus better supporting the climbing platform 2. It should be noted that the structure of the connecting crossbar is not limited; it can be a round steel pipe, square steel pipe, I-beam, channel steel, etc. Preferably, it is a steel pipe structure to provide attachment points for the climbing platform 2.
[0045] In another embodiment, the climbing channel includes a channel steel welded to the climbing section 13, and multiple connecting crossbars are fixed at intervals inside the channel steel. Both ends of the connecting crossbars pass through the web of the channel steel to provide attachment climbing points for the climbing platform 2. Designing the climbing channel as a channel steel structure can enhance the overall strength of the climbing channel.
[0046] The climbing section 13 is also cylindrical, and its diameter is not less than that of the standard section 12. In one embodiment, the climbing section 13 and the standard section 12 have the same diameter, and the climbing sections 13 are connected by flanges and high-strength bolts. The climbing section 13 and the standard section 12 are either welded together or connected by flanges and high-strength bolts. A connecting flange is fixed to the outer wall of the end face of the climbing section 13. The connection between two adjacent climbing sections 13 is achieved by aligning two connecting flanges and installing multiple high-strength bolts and nuts between the two connecting flanges.
[0047] In another embodiment, refer to Figure 5 The diameter of the climbing joint 13 is smaller than that of the standard joint 12. In this case, the top of the standard joint 12, which is connected to the climbing joint 13, is provided with a reduced-diameter section 121. One end of the reduced-diameter section 121 has the same diameter as the climbing joint 13, and the other end has the same diameter as the standard joint 12. The reduced-diameter section 121 allows for a stable connection between climbing joints 13 and standard joints 12 of different diameters. The reduced-diameter sections 121 of the climbing joint 13 and standard joint 12 are also connected by flanges and high-strength bolts.
[0048] Example 3
[0049] Example 3 is based on Example 1 or Example 2, such as... Figure 3 and Figure 5 As shown, a non-standard section 14 is also provided at the top of the main body. The length of the non-standard section 14 is different from the length of the standard section 12 or the length of the climbing section 13. It is used to adjust the overall height of the support column according to the actual situation of each support column, so as to match the support height of different points of the concrete conveying line. When the non-standard section 14 is connected to the standard section 12, the structure of the non-standard section 14 is the same as that of the standard section 12; when the non-standard section 14 is connected to the climbing section 13, the structure of the non-standard section 14 is the same as that of the climbing section 13.
[0050] It should be noted that, in the above embodiments, as Figure 6 As shown, each base section 11 and standard section 12 has several limiting keys 3 fixedly arranged around the inner or outer wall of one side for welding and fixing. The limiting keys 3 are partially welded to the inner or outer wall of the base section 11 and standard section 12, and partially extend beyond the end face of the base section 11 and standard section 12. The attached diagram only shows the case where they are welded to the inner wall. The area where the limiting keys 3 extend beyond the base section 11 and standard section 12 has a guide surface on its sidewall. Therefore, when installing the standard section 12 above the base section 11 or standard section 12, only the inner or outer wall of the upper standard section 12 needs to be abutted against the sidewall of the extended area of the multiple limiting keys 3 to achieve accurate positioning and hoisting of the upper standard section 12. The guide surface helps guide the lowering of the upper standard section 12, thus assisting in its alignment.
[0051] 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.
