Description

Technical Field

[0001] This utility model belongs to the technical field of concrete conveying equipment, and specifically relates to a telescopic material receiving and conveying section. Background Technology

[0002] The dam construction involves a large volume of concrete pouring, and traditional concrete pump trucks are insufficient to meet the efficiency requirements of dam construction. Currently, equipment using tower cranes for concrete transport exists. A tower crane includes a tower crane and a conveyor line between the tower crane and the concrete supply point. The conveyor line transports the concrete to the tower crane, and then the tower crane and other structures further transport the concrete to the pouring point.

[0003] Typically, a receiving section is set up between the concrete supply point and the conveying line. This receiving section receives the concrete supplied by the concrete supply point and transports it to the conveying line. For conveying distances where multiple conveying lines need to be supplied simultaneously, setting up a separate receiving section for each conveying line results in low utilization and poor economic efficiency. Furthermore, the number of concrete supply points differs from the number of conveying lines, making it impossible to set up a receiving section for each conveying line. Utility Model Content

[0004] This invention provides a telescopic material receiving and conveying section to solve the problem of supplying concrete to multiple conveying lines over short distances.

[0005] To solve the above-mentioned technical problems, the technical solution adopted by this utility model is as follows:

[0006] A telescopic material receiving and conveying section includes an outer feeding section and an inner feeding section. The outer feeding section is sleeved outside the inner feeding section, and the inner feeding section can slide relative to the outer feeding section and be housed inside the outer feeding section.

[0007] The external feeding section is equipped with a first driving device for driving the external feeding section to move, and the internal feeding section is equipped with a second driving device for driving the internal feeding section to move.

[0008] Furthermore, the first driving device includes a first walking drive wheel installed at the end of the external feeding section away from the internal feeding section.

[0009] Furthermore, the second drive device includes a second travel drive wheel mounted on the side of the inner feeding section away from the outer feeding section.

[0010] Furthermore, a sliding guide frame is provided in the area near the material conveying line. The second driving device includes a driving crane slidably mounted on the sliding guide frame. The driving crane is connected to the side of the inner feeding section near the material conveying line and is used to drive the inner feeding section to move.

[0011] Furthermore, the sliding guide frame includes two rows of columns, with connecting crossbars between the two rows of columns, and sliding rails connected below several connecting crossbars.

[0012] The sliding rail is arranged along the moving direction of the inner feeding section, and the extending direction of the sliding rail is perpendicular to the extending direction of the conveying line.

[0013] Furthermore, multiple support blocks are spaced apart within the travel range of the external feeding section, and roller supports for supporting the external feeding section are installed on the support blocks.

[0014] Furthermore, a loading space for dump trucks is provided below the mixing tower, and the external feeding section can move towards the conveyor line until the external feeding section is completely removed from the loading space.

[0015] Furthermore, the horizontal distance between the second walking drive wheel and the discharge end of the inner feeding section is S1, and S1 is not less than the total arrangement width of the multiple conveying lines.

[0016] When the external feeding section moves out of the feeding space as a whole, and the second driving wheel comes into contact with the external feeding section, the discharge end of the internal feeding section is located on the side of the conveying line closer to the mixing tower.

[0017] Furthermore, all the support blocks are located outside the feeding space, and when the external feeding section moves out of the feeding space, the first walking drive wheel abuts against the support block closest to the feeding space.

[0018] Furthermore, the external feeding section includes an external support truss, and the internal feeding section includes an internal support truss. Both the external support truss and the internal support truss are equipped with belt conveyors for transporting concrete.

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

[0020] 1. This application achieves the sliding of the inner feeding section relative to the outer feeding section through the second driving device, thereby enabling the feeding of multiple conveying lines by the relative sliding of the inner feeding section while maintaining stable support through the interlocking of the outer feeding section and the inner feeding section; at the same time, the outer feeding section is equipped with a first driving device, which can drive the outer feeding section to slide relative to the inner feeding section to free up space below the concrete supply point, thereby enabling the concrete supply point to be used for dump truck loading.

[0021] 2. The installation of support piers and roller supports can stably support the area where the external feeding section and the internal feeding section are interlocked, thereby providing stable support for the external feeding section and the internal feeding section.

[0022] 3. The second drive unit has two design forms: a second traveling drive wheel and a drive crane. This allows for different arrangements to be selected based on the actual site conditions, in order to adapt to more complex working conditions on site. Attached Figure Description

[0031] 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.

[0032] Example 1

[0033] like Figures 1 to 4As shown, a telescopic material receiving and conveying section includes an outer feeding section 1 and an inner feeding section 2. The outer feeding section 1 is sleeved on the outer side of the inner feeding section 2, and the inner feeding section 2 can slide relative to the outer feeding section 1 and be fully or partially housed inside the outer feeding section 1. The outer feeding section 1 includes an outer support truss, and the inner feeding section 2 includes an inner support truss. Both the outer and inner support trusses are equipped with belt conveyors for transporting concrete. The concrete is transported from the concrete supply point 100 to the conveying line 200 via the belt conveyors. The outer support truss, sleeved on the inner support truss, provides support for the inner support truss and includes 53 sliding rails.

[0034] A first drive device for moving the external feeding section 1 is installed on the external feeding section 1, and a second drive device for moving the internal feeding section 2 is installed on the internal feeding section 2. Specifically, the first drive device includes a first travel drive wheel 3, which is installed on the side of the external feeding section 1 near the concrete supply point 100. It is used to drive the external feeding section 1 to move and lock its position. The structure of the first travel drive wheel 3 is based on a relatively mature existing manufacturing process, which will not be described in detail here.

[0035] The second drive device includes a second travel drive wheel 4, which is installed on the side of the inner feeding section 2 away from the outer feeding section 1. The section between the discharge end of the inner feeding section 2 facing the conveyor line 200 and the second travel drive wheel 4 is a cantilever section. The length S1 of the cantilever section is not less than the total arrangement width S2 of the multiple conveyor lines 200, so as to achieve feeding material to each conveyor line 200 without interfering with the second travel drive wheel 4 and the conveyor line 200.

[0036] Multiple support piers 7 are intermittently poured within the travel range of the external feeding section 1. The pouring elevation and pouring height of the support piers 7 are adjusted according to the actual transportation situation. Roller supports 71 for supporting the external feeding section 1 are installed on the support piers 7. By setting the roller supports 71, the stable support of the external feeding section 1 and the internal feeding section 2 can be met, while not hindering the external feeding section 1 from sliding relative to the roller supports 71.

[0037] In addition, a loading space 8 for dump trucks is provided below the concrete supply point 100. The area of ​​the loading space 8 must be large enough to allow dump trucks to park and drive out. The external feeding section 1 can move towards the conveyor line 200 until it completely leaves the loading space 8. The position of the second driving wheel 4 and the length of the external feeding section 1 and the internal feeding section 2 are such that when the external feeding section 1 moves out of the loading space 8 and the second driving wheel 4 comes into contact with the external feeding section 1, the discharge end of the internal feeding section 2 is located on the side of the conveyor line 200 closer to the mixing plant.

[0038] All support blocks 7 are set outside the feeding space 8. At the same time, the limit setting range of the support blocks 7 must at least meet the requirement that when the external feeding section 1 moves out of the feeding space 8, the first traveling drive wheel 3 abuts against the support block 7 closest to the feeding space 8.

[0039] When feeding materials to the conveying line 200, the first driving device can drive the external feeding section 1 to move below the concrete supply point 100, and then the second driving device can drive the internal feeding section 2 to move until the discharge end of the internal feeding section 2 moves above each conveying line 200, thereby realizing the feeding of multiple conveying lines 200.

[0040] When supplying concrete to dump trucks at the concrete supply point 100, the external feeding section 1 and the internal feeding section 2 can be driven to move simultaneously, ensuring that the second driving wheel 4 does not interfere with the conveying line 200. Simultaneously, the external feeding section 1 is completely moved out of the loading space 8, thus enabling loading of the dump trucks. This application's telescopic receiving and transporting section is suitable for situations where the number of conveying lines 200 is relatively small, for example, each telescopic receiving and transporting section only needs to correspond to two to three conveying lines 200 for loading, and where dump trucks can easily move to the concrete supply point 100 for receiving at the construction site.

[0041] Example 2

[0042] Reference Figure 3 and Figure 4 The difference between Embodiment 2 and Embodiment 1 is that a sliding guide rail frame 5 is provided in the area near the conveyor line 200, and the second driving device includes a drive crane 6 slidably mounted on the sliding guide rail frame 5. The drive crane 6 is connected to the side of the inner feeding section 2 near the conveyor line 200 and is used to suspend and drive the inner feeding section 2 to move. The drive crane 6 is existing technology, and a suitable load-bearing drive machine can be selected from the market according to the transportation volume requirements.

[0043] Specifically, the sliding guide frame 5 includes double rows of columns 51, with connecting crossbars 52 between the double rows of columns 51. Several connecting crossbars 52 are connected to sliding rails 53 below them. The sliding rails 53 can be in the shape of I-beams to accommodate the suspension and sliding of the drive crane 6. The sliding rails 53 are arranged along the moving direction of the inner feeding section 2, and the extending direction of the sliding rails 53 is perpendicular to the extending direction of the conveyor line 200. By setting up double rows of columns 51, installation space is provided for the material conveying section of this application, preventing interference between the material conveying section and the sliding guide frame 5 during movement.

[0044] Compared to Example 1, Example 2 allows for a wider range of support blocks 7 and roller supports 71. Since the outer feeding section 1 is fitted outside the inner feeding section 2, the support blocks 7 and roller supports 71 do not interfere with the movement of the inner feeding section 2. By setting a greater number of support blocks 7 and roller supports 71, more stable support can be achieved for the outer feeding section 1 and the inner feeding section 2.

[0045] 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.
