Description

Technical Field

[0001] This utility model belongs to the technical field of concrete conveying equipment, and specifically relates to a single-layer flexible material supply 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 mixing plant to the tower crane via a series of interconnected feeding 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 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] Currently, there are dedicated material supply lines for transporting and supplying concrete from concrete supply points to concrete material supply lines. If each concrete supply point needs to be supplied by four to five concrete material supply lines, each material supply line will need to connect to four to five concrete material supply lines for feeding. This is difficult to achieve using traditional material supply equipment, such as belt conveyors and screw conveyors. Utility Model Content

[0005] This utility model provides a single-layer flexible feeding structure to solve the problem that a single feeding line needs to feed multiple concrete feeding lines.

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

[0007] A single-layer flexible feeding structure includes a feeding line, one end of which is located on the side of the concrete supply point away from the concrete feeding line, and the other end of which is located on the side of the concrete feeding line away from the concrete supply point.

[0008] The concrete feeding lines are all located below the feed line, and the extension direction of the concrete feeding lines is perpendicular to the extension direction of the feed line. The feed line is equipped with a mobile unloading trolley for feeding the concrete feeding line. The mobile unloading trolley moves along the feed line and realizes multi-point unloading.

[0009] Furthermore, a fixed support frame is provided below the feeding line, with at least two fixed support frames respectively located near both ends of the feeding line.

[0010] Furthermore, the fixed support frame is a truss structure.

[0011] Furthermore, a support hanger is provided around the feeding line, and a suspension rope assembly is provided on the support hanger, which is connected to the feeding line.

[0012] Furthermore, one or more suspension rope assemblies are provided, and each suspension rope assembly is located between two fixed support frames on the outermost side of the feeding line.

[0013] Furthermore, the vertical distance between the feeding line and the ground is greater than the height of the dump truck.

[0014] Furthermore, a lifting pier is cast beneath each concrete feeding line, and the overall height of the concrete feeding line after it is installed above the lifting pier corresponds to the height of the dump truck.

[0015] Furthermore, a recycling bin for receiving residual concrete is provided below the discharge end of the feeding line.

[0016] Furthermore, the support frame includes two rows of columns, with connecting crossbars between the two rows of columns, and mounting rods connected below several connecting crossbars, with the suspension rope assembly mounted on the mounting rods.

[0017] Furthermore, the feeding line includes a support truss and a belt conveyor, the belt conveyor being mounted on the support truss;

[0018] The suspension rope assembly is connected to the support truss, the mobile unloading trolley is mounted on the belt conveyor, and the conveyor belt passes around the mobile unloading trolley.

[0019] The present invention can achieve the following beneficial effects:

[0020] 1. This application solves the problem of a single supply line supplying multiple concrete delivery lines by setting up a supply line that spans a concrete supply point and multiple concrete delivery lines, and by setting up a mobile unloading trolley on the supply line. The mobile unloading trolley can unload the concrete transported on the supply line at multiple points laterally, and then select to transport the concrete transported on the supply line to the corresponding concrete delivery line or dump truck as needed.

[0021] 2. Fixed support frames should be installed on at least both sides of the material supply line to ensure stable support of the material supply line and provide more space for the layout of the concrete delivery line and the movement of dump trucks.

[0022] 3. Install support hangers and install multiple suspension rope assemblies at intervals on the support hangers to provide multiple tie points for the feeding line, so that the section of the feeding line located between two adjacent fixed support frames can also be stably lifted, thereby maintaining the stability of the structure.

[0028] 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.

[0029] like Figure 1 As shown, a single-layer flexible material supply structure includes a material supply line 1. One end of the material supply line 1 is located on the side of the concrete supply point 100 away from the concrete feeding line 200, and the other end is located on the side of the concrete feeding line 200 away from the concrete supply point 100. All concrete feeding lines 200 are located below the material supply line 1, and the extension direction of the concrete feeding lines 200 is perpendicular to the extension direction of the material supply line 1. A mobile unloading trolley 2 is installed on the material supply line 1 to supply material to the concrete feeding lines 200. The mobile unloading trolley 2 moves along the material supply line 1, thereby achieving multi-point unloading.

[0030] Specifically, the feeding line 1 includes a supporting truss 11 and a belt conveyor. The belt conveyor is installed on the supporting truss 11, and the mobile unloading trolley 2 is installed on the belt conveyor. The conveyor belt for transporting concrete bypasses the mobile unloading trolley 2. The mobile unloading trolley 2 is existing technology and can output the concrete conveyed on the conveyor belt from both sides of the mobile unloading trolley 2, thereby realizing the feeding of multiple concrete feeding lines 200 below.

[0031] When setting up the concrete feeding line 200, a recycling bin 7 should be installed below the discharge end of the feeding line 1. For concrete that is not completely unloaded by the mobile unloading trolley 2, the remaining concrete can be transported into the recycling bin 7 when the feeding line 1 is transported to the end, so as to avoid concrete waste.

[0032] Furthermore, a fixed support frame 3 is installed below the feeding line 1. The fixed support frame 3 has a truss structure, which enhances its supporting strength. The number of fixed support frames 3 is adjusted according to the length of the feeding line 1; the longer the feeding line 1, the more fixed support frames 3 are required, but at least two fixed support frames 3 must be installed near both ends of the feeding line 1. The concrete feeding line 200 can be arranged between the two fixed support frames 3 located at both ends of the feeding line 1, and multiple lines can be arranged as needed.

[0033] In addition, by adjusting the installation position of the fixed support frame 3, a loading section for dump trucks 300 is reserved below the feeding line 1. The size of this loading section needs to be large enough for the dump truck 300 to enter, load the concrete dropped from the mobile unloading trolley 2, and then exit. By reserving the loading section, the feeding structure of this application can not only transport materials for multiple concrete feeding lines 200, but also for dump trucks 300.

[0034] It should be noted that the vertical distance between the feed line 1 and the ground is greater than the height of the dump truck 300, thus making it possible for the mobile unloading trolley 2 to feed the dump truck 300. Correspondingly, a lifting pier 6 is cast below each concrete feed line 200. The casting height of the lifting pier 6 is adaptively adjusted according to the terrain. The design of the lifting pier 6 is based on the principle that the overall height of the concrete feed line 200 after installation above the lifting pier 6 corresponds to the height of the dump truck 300. If there are special terrain conditions that allow the height of the dump truck 300 to correspond even without the casting of the lifting pier 6, then the lifting pier 6 can be omitted. By setting up the lifting pier 6 to raise the concrete feed line 200, the falling path of the concrete is shorter when the mobile unloading trolley 2 delivers material to the concrete feed line 200, reducing the impact force of the concrete on the concrete feed line 200.

[0035] A support hanger 4 is also provided around the feeding line 1. The support hanger 4 includes two rows of columns 41, with connecting crossbars 42 between the two rows of columns 41. Several mounting rods 43 are connected to the bottom of the connecting crossbars 42. By setting up two rows of columns 41, the structural strength of the support hanger 4 can be enhanced, and at the same time, installation space can be provided for the feeding line 1 of this application to prevent interference between the feeding line 1 and the support hanger 4 when it moves.

[0036] A suspension rope assembly 5 is installed on the support hanger 4. The suspension rope assembly 5 is mounted on the mounting rod 43 and connected to the support truss 11 for tying the support truss 11. If the arrangement density of the fixed support frames 3 is large, resulting in a long suspended section between two adjacent fixed support frames 3, the middle section of the suspended section will experience a large bending moment due to the structural weight and the concrete above. The suspension rope assembly 5 is used to balance the downward bending moment force borne by the support truss 11.

[0037] One or more suspension rope assemblies 5 are provided, and each suspension rope assembly 5 is located between the two fixed support frames 3 on the outermost side of the feeding line 1. In addition, at least one suspension rope assembly 5 is provided in the feeding section.

[0038] This application presents a single-layer flexible material supply structure suitable for construction conditions where the concrete delivery lines 200 are arranged along their entire length at a relatively high height, and where a large number of concrete delivery lines 200 are installed. Because the material supply line 1 is stationary and simultaneously supported and connected using fixed support frames 3 and support hangers 4, the structure exhibits high stability. This allows for the installation of larger material supply lines 1, increasing the concrete transport capacity and enabling the material supply line 1 to supply four to six concrete delivery lines 200.

[0039] 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.
