Description

Technical Field

[0001] This utility model belongs to the technical field of concrete conveying equipment, and specifically relates to a double-layer material receiving and 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, thus achieving efficient pouring on the construction site.

[0003] Typically, multiple tower cranes are deployed at 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 at the construction site. Therefore, one concrete supply point needs to supply concrete to multiple concrete feeding lines.

[0004] Meanwhile, there are also some small-volume concrete pouring needs at the construction site, such as the construction of supporting buildings around the main structure. In this case, there is no need to use a concrete delivery line to transport concrete; simply use dump trucks to load the concrete and transport it to the pouring point. If the concrete is transported from the concrete supply point to the concrete delivery line using a traditional concrete conveying structure, the concrete conveying structure is usually set up below the concrete supply point for receiving the material. However, in this case, the concrete supply point cannot be used to load dump trucks. Utility Model Content

[0005] This utility model provides a double-layer material receiving and conveying structure to solve the problem of difficulty in matching concrete supply points with multiple concrete delivery lines and dump truck loading.

[0006] To solve the above-mentioned technical problems, the technical solution adopted by this utility model is as follows:

[0007] A double-layer material receiving and conveying structure includes an upper conveying section and a lower conveying section. A supporting slide is provided near the concrete supply point. One end of the upper conveying section is slidably connected to the lower part of the supporting slide, and the other end overlaps the upper part of the lower conveying section. The upper conveying section can slide relative to the lower conveying section.

[0008] A mobile unloading trolley is slidably installed on the lower conveying section, and the mobile unloading trolley is used to transport the concrete material on the lower conveying section to the concrete feeding line.

[0009] Furthermore, multiple sets of fixed support frames are spaced apart below the lower conveying section, and the concrete feeding line is located below the lower conveying section, with the extension direction of the concrete feeding line perpendicular to the extension direction of the lower conveying section.

[0010] Furthermore, the upper conveying section includes an upper support truss, the lower conveying section includes a lower support truss, and belt conveyors for conveying concrete are installed on the upper support truss and the lower support truss.

[0011] Furthermore, an organic tail section is provided on the side of the upper support truss near the concrete supply point. The sliding limit of the organic tail section is located on the support slide and drives the upper conveying section to move relative to the lower conveying section.

[0012] The upper support truss is equipped with a machine head section on the side near the lower conveying section, which is used to smoothly convey concrete onto the lower conveying section.

[0013] Furthermore, the tail section is positioned at a higher height than the head section.

[0014] Furthermore, a sliding roller is provided at the bottom of the upper support truss near the head section, and the sliding roller moves along the upper crossbar of the lower support truss.

[0015] Furthermore, a discharge space is provided below the concrete supply point. The upper conveying section can move along the supporting slide until it is located below the concrete supply point outlet, or move along the supporting slide until the upper conveying section is completely removed from the discharge space.

[0016] Furthermore, multiple concrete feeding lines can be installed below the lower conveying section, and a recycling line for receiving residual concrete is installed below the discharge end of the lower conveying section.

[0017] Furthermore, the fixed support frame is a truss structure.

[0018] Furthermore, the supporting carriage includes two rows of spaced columns, with connecting crossbars between the two rows of columns, and sliding guide rails connected below several connecting crossbars, the sliding guide rails extending along the moving direction of the upper conveying section;

[0019] The tail section includes a drive roller, which is supported on the sliding guide rail and slides along the sliding guide rail.

[0020] The present invention can achieve the following beneficial effects:

[0021] 1. This application includes an upper conveying section and a lower conveying section. The upper conveying section can slide relative to the lower conveying section. When the upper conveying section slides below the concrete supply point, concrete can be transported to the lower conveying section. A mobile unloading trolley is installed on the lower conveying section, and the movement of the mobile unloading trolley enables the supply of concrete to multiple concrete delivery lines. When the upper conveying section slides below the concrete supply point and creates space, it provides space for dump trucks to load concrete. Thus, the material receiving and transporting structure of this application can achieve the connection and supply of concrete to a single concrete supply point, dump trucks, and multiple concrete delivery lines.

[0022] 2. This application provides multiple truss-structured fixed support frames below the lower conveying section, which can stably support the lower conveying section, the moving unloading trolley, and the downward pressure applied to the lower conveying section by the upper conveying section.

[0023] 3. A head section is installed and sliding rollers are installed around the head section to make the upper conveying section move more smoothly relative to the lower conveying section. The head section can transport the concrete output from the upper conveying section to the lower conveying section through a shorter path, reducing the impact force on the lower conveying section when the concrete falls to the lower conveying section and mitigating the segregation and splashing of concrete.

[0030] 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.

[0031] like Figure 1 and Figure 2 As shown, a double-layer material receiving and conveying structure includes an upper conveying section 1 and a lower conveying section 2. The upper conveying section 1 is set at a higher elevation than the lower conveying section 2, and a supporting slide 3 is installed near the concrete supply point 100. One end of the upper conveying section 1 is slidably connected to the supporting slide 3, and the other end overlaps the lower conveying section 2, allowing the upper conveying section 1 to slide relative to the lower conveying section 2. Concrete falls from the concrete supply point 100 to the upper conveying section 1, is transported through the upper conveying section 1 to the lower conveying section 2, and then transported through the lower conveying section 2 to the concrete feeding line 200. Multiple concrete feeding lines 200 are provided, and the extension direction of the concrete feeding lines 200 is perpendicular to the extension direction of the upper conveying section 1. All concrete feeding lines 200 are located below the lower conveying section 2.

[0032] Specifically, the upper conveying section 1 includes an upper support truss 11, and the lower conveying section 2 includes a lower support truss 21. Both the upper support truss 11 and the lower support truss 21 are equipped with belt conveyors for conveying concrete. Additionally, a mobile unloading trolley 5 is slidably mounted on the lower conveying section 2. The mobile unloading trolley 5 is mounted on the belt conveyor and can move along it. The concrete conveyor belt bypasses the mobile unloading trolley 5, delivering the concrete into it. The mobile unloading trolley 5 can deliver concrete from both sides to the concrete feeding line 200. The mobile unloading trolley 5 is an existing finished technology, and its specific structure will not be described in detail here.

[0033] Furthermore, a discharge space 6 is provided below the concrete supply point 100. The discharge space 6 is used for dump trucks 300 to enter, connect to the concrete discharge port to receive concrete, and then exit. This application achieves the clearance of the discharge space 6 by moving the upper conveying section 1, allowing the dump truck 300 to load concrete into the discharge space 6. During this stage, the upper conveying section 1 moves along the support slide 3 until the upper conveying section 1 is completely removed from the discharge space 6. Alternatively, the upper conveying section 1 can be moved to a position below the concrete supply point 100 to receive concrete. The concrete is then transported to the mobile discharge trolley 5 via the upper conveying section 1 and the lower conveying section 2. The mobile discharge trolley 5 then transports the concrete from the lower conveying section 2 to multiple concrete feeding lines 200.

[0034] Multiple sets of fixed support frames 4 are spaced apart below the lower conveying section 2. The fixed support frames 4 are steel truss structures, and multiple concrete feeding lines 200 can be arranged at intervals between adjacent sets of fixed support frames 4. By setting the fixed support frames 4 as truss structures, the support strength of the fixed support frames 4 can be enhanced, so as to more stably bear the weight of the upper lower conveying section 2, the mobile unloading trolley 5, and the downward pressure applied to the lower conveying section 2 by the upper conveying section 1.

[0035] Additionally, a recycling line 7 for receiving residual concrete is installed below the discharge end of the lower conveying section 2. Normally, the concrete transported on the lower conveying section 2 is transferred to a mobile unloading trolley 5, which then unloads it laterally onto the concrete feeding line 200. However, during unloading, concrete residue may remain on the conveyor belt. To prevent concrete from falling to the ground and contaminating the construction site when it reaches the discharge end of the lower conveying section 2, a recycling line 7 is installed at the discharge end of the lower conveying section 2. The recycling line 7 can transport the collected concrete to a centralized concrete recycling area or circulate it to the concrete supply point 100. The specific transportation path of the recycling line 7 can be designed reasonably according to the actual conditions of the construction site.

[0036] In a preferred embodiment, the upper conveying section 1 includes a tail section 13 and a head section 14. The tail section 13 is disposed on the side of the upper support truss 11 near the concrete supply point 100, and the head section 14 is disposed on the side of the upper support truss 11 near the lower conveying section 2. The tail section 13 is confined to the support slide 3, and a drive source is disposed within the tail section 13. The drive source drives the tail section 13 to move along the support slide 3, thereby realizing the movement of the upper conveying section 1 relative to the lower conveying section 2.

[0037] The shape of the head section 14 is rationally designed to create a concrete conveying ramp. This ramp allows the concrete to be smoothly conveyed to the lower conveying section 2, reducing the possibility of concrete splashing when it falls from the upper conveying section 1 to the lower conveying section 2. It also reduces the impact on the conveyor belt on the lower conveying section 2. The tail section 13 is set at a higher height than the head section 14. This allows for a more stable connection between the tail section 13 and the supporting carriage 3, and also creates a downward slope on the upper surface of the upper conveying section 1, which facilitates concrete transport.

[0038] A sliding roller 15 is provided at the bottom of the upper support truss 11 near the head section 14. The sliding roller 15 is arranged in two rows, allowing it to move along the two main crossbars above the lower support truss 21. By setting the sliding roller 15, the resistance to the movement of the upper conveying section 1 relative to the lower conveying section 2 can be reduced, resulting in a smaller and more labor-saving driving force for the upper conveying section 1.

[0039] Furthermore, the supporting slide 3 includes two rows of spaced columns 31, with connecting crossbars 32 between the two rows of columns 31. Several connecting crossbars 32 are connected to sliding guide rails 33 below them. Specifically, the sliding guide rails 33 can be I-beams, extending along the moving direction of the upper conveying section 1. The tail section 13 includes drive rollers 16, which are clamped to both sides of the web of the sliding guide rail 33 and supported on the lower flange of the sliding guide rail 33, thereby achieving installation limitation and enabling sliding along the sliding guide rail 33.

[0040] By setting up double rows of columns 31, the overall structural strength of the support slide 3 can be enhanced, and the supporting force on the upper conveying section 1 can be increased. At the same time, it can also provide installation space for the upper conveying section 1 and the lower conveying section 2 of this application, and provide driving space for the dump truck 300, preventing the support slide 3 from interfering with other structures.

[0041] 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.
