Description

Technical Field

[0001] This utility model belongs to the technical field of concrete conveying equipment, and specifically relates to a walking single-layer material conveying structure. Background Technology

[0002] Currently, there is a technology for transporting concrete using a tower crane belt conveyor. This technology involves adding a suspended belt conveyor system to a tower crane to form a combined system that integrates horizontal and vertical transportation. Concrete is transported from the concrete supply point to the tower crane via a series of overlapping feed lines. The suspended belt conveyor system then transports the concrete from the tower crane to the pouring point, thereby achieving efficient pouring on the construction site.

[0003] Typically, multiple tower cranes are deployed on a construction site, each equipped with a suspended belt conveyor system and a concrete feeding line. Due to the large volume of concrete produced by a single concrete mixing plant, the number of concrete supply points is usually less than the number of tower cranes deployed on the construction site. Therefore, how to achieve the goal of feeding a large number of concrete feeding lines with fewer concrete supply points is a problem that needs to be solved during construction. Utility Model Content

[0004] This utility model provides a mobile single-layer material conveying structure to solve the problem of mismatch between the number of concrete supply points and concrete delivery lines during the transportation of concrete using a tower conveyor.

[0005] To solve the above-mentioned technical problems, the technical solution adopted by this utility model is as follows: A mobile single-layer material conveying structure includes a material conveying section for conveying material to a concrete feeding line, wherein the extension direction of the concrete feeding line is perpendicular to the extension direction of the material conveying section. Several support blocks are spaced apart below the material conveying section. Each support block includes a roller support for supporting the material conveying section, and the material conveying section can slide relative to the roller support. The bottom of the material conveying section is also provided with drive wheels for driving the material conveying section to move horizontally. Furthermore, the drive wheels are located on the side of the material transport section closest to the concrete supply point.

[0006] Furthermore, the support pier closest to the concrete supply point is the first support pier, and the distance between the drive wheel and the first support pier is greater than the overall width of the multiple concrete feeding lines.

[0007] Furthermore, a loading space for dump trucks is provided below the concrete supply point, and the distance between the drive wheels and the first support pier is sufficient for the material transport section to move towards the concrete delivery line until the entire material transport section moves out of the loading space.

[0008] Furthermore, a sliding hanger is installed on the side of the material conveying section near the mixing plant, and a suspension cable is slidably installed on the sliding hanger, which is connected to the material conveying section; When the material transport section supplies concrete to the concrete delivery line, the connection point between the suspension cable and the material transport section is located between the first support pier and the drive wheel.

[0009] Furthermore, the material conveying section includes a supporting truss and a belt conveyor, the belt conveyor being installed on the supporting truss; The suspension cable is connected to the support truss, and the support truss is supported above the roller support.

[0010] Furthermore, support piers can also be installed between adjacent concrete feeding lines and on the side of the concrete feeding line away from the mixing plant.

[0011] Furthermore, when the material conveying section is a concrete feeding line closest to the concrete supply point, the location of the suspension cable is the first point. When the material transport section moves toward the concrete feeding line until it is completely removed from the loading space, the position of the suspension cable is the second position. The sliding hanger is installed within a range that includes at least the section between the first and second points.

[0012] Furthermore, the sliding hanger includes two rows of columns, with connecting crossbars between the two rows of columns, and sliding rails connected below several connecting crossbars, with the suspension cables slidably installed on the sliding rails.

[0013] Furthermore, the roller support includes two rows of spaced-apart support rollers, which are respectively supported under the two main crossbars of the support truss.

[0014] The present invention can achieve the following beneficial effects: 1. The material conveying structure of this application drives the material conveying section to move as a whole by driving the walking wheels. At the same time, several roller supports are set under the material conveying section to achieve stable support for the material conveying section, thereby meeting the feeding of multiple concrete feeding lines. This allows one material conveying section to feed multiple concrete feeding lines, solving the problem of mismatch between the number of concrete supply points and the number of concrete feeding lines.

[0015] 2. The loading space is set up so that the material transport section can slide out of the loading space as a whole, thereby allowing dump trucks to drive into the loading space for loading, and enabling the concrete supply point to provide concrete for more construction site pouring methods.

[0016] 3. Install a sliding hanger and install suspension cables on the sliding hanger. The suspension cables pull the material transport section upward to provide a connection between the material transport section suspended between the drive wheels and the support pier, thereby improving the overall structural stability of the material transport section.

[0019] 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.

[0020] like Figure 1 and Figure 2 As shown, a walking single-layer material conveying structure includes a material conveying section 1 for conveying material to a concrete feeding line 200. The material conveying section 1 receives material from a concrete supply point 100 and transports the concrete to multiple concrete feeding lines 200, wherein the extension direction of the concrete feeding line 200 is perpendicular to the extension direction of the material conveying section 1.

[0021] The material conveying section 1 includes a supporting truss 11 and a belt conveyor. The supporting truss 11 provides a stable mounting platform for the belt conveyor, which is used to transport concrete. Drive wheels 3 are installed at the bottom of the material conveying section 1, specifically mounted on the supporting truss 11, and positioned on the side of the material conveying section 1 closest to the concrete supply point 100. The drive wheels 3 drive the horizontal movement of the material conveying section 1 and control its position locking. The drive wheels 3 utilize existing commercial technology, allowing for the selection of appropriate devices based on power and load-bearing requirements.

[0022] Several support piers 2 are spaced apart below the material conveying section 1. The support piers 2 are located on the side of the drive wheels 3 facing the concrete delivery line 200. Each support pier 2 includes a pier base 21 and roller supports 22 mounted on the pier base 21 to support the material conveying section 1. The roller supports 22 include double rows of spaced support rollers, which are respectively supported under the two main crossbars of the support truss 11. This allows the roller supports 22 to both stably support the material conveying section 1 and slide relative to it to meet the movement requirements of the material conveying section 1.

[0023] By driving the walking wheels 3 and supporting the rollers 22, the overall position of the material conveying section 1 can be moved. The concrete feeding line 200 is located below the material conveying section 1. By moving the material conveying section 1, the outlet of the material conveying section 1 is aligned with each concrete feeding line 200, thereby realizing the concrete conveying of one material conveying section 1 to multiple concrete feeding lines 200.

[0024] The location of the support pier 2 is not limited to the area between the concrete delivery line 200 and the concrete supply point 100. The support pier 2 can also be set between adjacent concrete delivery lines 200 and on the side of the concrete delivery line 200 away from the mixing plant, so as to meet the stable support of the material transport section 1 in various position states.

[0025] It should be noted that the design length of the material conveying section 1 satisfies the following condition: when the material conveying section 1 supplies material to the concrete feeding line 200 furthest from the concrete supply point 100, the side of the material conveying section 1 closest to the concrete supply point 100 can still be located below the concrete supply point 100 and stably receive the concrete supplied by the concrete supply point 100.

[0026] The support pier 2 closest to the concrete supply point 100 is defined as the first support pier 23. The distance between the drive wheel 3 and the first support pier 23 is greater than the overall layout width of the multiple concrete feeding lines 200. Only in this way can the concrete supply from the material transport section 1 to each concrete feeding line 200 be achieved without interference between the drive wheel 3 and the first support pier 23.

[0027] In addition, a loading space 4 for dump trucks 300 to load materials is provided below the concrete supply point 100. The distance between the drive wheels 3 and the first support pier 23 is sufficient to allow the material transport section 1 to move towards the concrete delivery line 200 until the entire material transport section 1 is removed from the loading space 4. When small-volume concrete pouring is required at the construction site, dump trucks 300 are usually used to transport concrete to the construction site. At this time, the material transport section 1 can be moved out of the loading space 4, making it possible for the dump trucks 300 to receive materials at the concrete supply point 100. This allows the concrete supply point 100 to supply materials not only to multiple concrete delivery lines 200, but also to dump trucks 300.

[0028] Furthermore, a sliding hanger 5 is installed on the side of the material transport section 1 near the concrete supply point 100. The sliding hanger 5 includes two rows of columns 51, with connecting crossbars 52 between the two rows of columns 51. Several connecting crossbars 52 are connected to sliding rails 53 below, and suspension cables 6 are slidably installed on the sliding rails 53. By setting up two rows of columns 51, the structural strength of the sliding hanger 5 can be enhanced, and installation space can also be provided for the material transport section 1 of this application to prevent interference between the material transport section 1 and the sliding hanger 5 when the material transport section 1 moves.

[0029] A suspension cable 6 is slidably mounted on the sliding hanger 5. The suspension cable 6 is connected to the support truss 11. When the material conveying section 1 is supplied by the concrete feeding line 200, the connection point between the suspension cable 6 and the material conveying section 1 is located between the first support pier 23 and the drive wheel 3. If there are many concrete feeding lines 200, the length of the suspended section of the support truss 11 between the drive wheel 3 and the first support pier 23 will increase accordingly. By setting the suspension cable 6, an upward tension force is provided to the suspended section of the support truss 11 between the drive wheel 3 and the first support pier 23, so that the downward bending moment generated inside the support truss 11 can be reduced, thereby maintaining the force balance of the support truss 11 and reducing the possibility of deformation of the support truss 11.

[0030] Meanwhile, when the material transport section 1 supplies concrete to the concrete feeding line 200 closest to the concrete supply point 100, the location of the suspension cable 6 is the first point; when the feeding line moves towards the concrete feeding line 200 until it is completely removed from the loading space 4, the location of the suspension cable 6 is the second point; and the sliding gantry 5 is installed within a range that includes at least the section between the first and second points. This ensures that the suspension cable 6 can provide tension to the supporting truss 11 in any state of the material transport section 1.

[0031] This application provides support for the material transport section through support piers and roller supports, which provides strong support and can bear large and heavy material transport sections. Therefore, the walking single-layer material transport structure of this application is suitable for working conditions with a large amount of concrete transport.

[0032] 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.
