Description

Technical Field

[0001] This utility model belongs to the technical field of concrete conveying equipment, and specifically relates to a fixed feeding 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, a construction solution using tower cranes for concrete transportation exists. A tower crane typically consists of a concrete conveyor line and a tower crane. The concrete conveyor line can transport concrete over long distances from the concrete supply point to the tower crane.

[0003] Because the geological and topographical conditions of each project are different, the design height of the concrete supply point is also different, which in turn leads to different layouts of the concrete conveying line. Therefore, it is necessary to provide a concrete conveying line that can be adapted to different terrain conditions. Utility Model Content

[0004] This invention provides a fixed feeding and conveying section, enabling the concrete conveying line to be arranged to adapt to different terrains.

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

[0006] A fixed feeding conveyor section includes a conveyor line, and a support system for supporting the conveyor line is provided below the conveyor line. One end of the conveyor line is hinged to the support system, and the other end is slidably connected to the support system.

[0007] The support system includes multiple support seats disposed below the feed line, the feed line being confined within the support seats and capable of sliding relative to the support seats.

[0008] Furthermore, the supporting system includes a first side support and a second side support located on both sides, and one or more intermediate supports located between the first side support and the second side support.

[0009] Furthermore, a rolling support is provided at the top of the first side support, one end of the feed line is supported on the rolling support and can slide relative to the rolling support; the other end of the feed line is hinged to the second side support.

[0010] Furthermore, the first side support is a base pier or column, the second side support is a base pier or column, and the middle support is a base pier or column.

[0011] Furthermore, the support base includes a sliding support mounted on the top of the intermediate support, the sliding support supporting a portion of the conveyor line that rotates relative to the intermediate support.

[0012] Furthermore, the support base also includes a rolling support mounted on top of the intermediate support, the rolling support supporting a portion of the conveyor line to rotate relative to the intermediate support.

[0013] Furthermore, the material conveying line includes multiple truss units spliced ​​together in sequence, and the truss unit includes a standard truss and a non-standard truss for adjusting the length of the material conveying line.

[0014] Furthermore, the conveying line includes an inclined section with an elevation difference between its two ends, and rotating mounting points are provided at both ends of the inclined section.

[0015] Furthermore, at the rotational mounting point, adjacent truss units are either rotatably connected only by their upper chords or only by their lower chords.

[0016] Furthermore, the rolling support includes a plurality of rollers supporting the truss unit below, and the sliding support includes a limiting support plate supporting the truss unit below.

[0017] The present invention can achieve the following beneficial effects:

[0018] 1. One end of the material conveyor line of this application is hinged to the lower support system, and the other end is slidably connected to the support system. The middle section is supported by a support seat, and the material conveyor line can slide relative to the support seat. This allows the material conveyor line of this application to be fixed to the lower support system through the hinge point, and to flexibly adjust its position during assembly through the sliding connection with the support seat. When special deformation requirements occur during operation, there can also be deformation, so that the material conveyor line can adaptively adjust its position to meet stable support.

[0019] 2. Rolling supports are installed on inclined sections, making it easier for the conveyor line to slide relative to the rolling supports. This allows for quick assembly and stable support at different inclination angles, overcoming the drawback of fixed supports causing internal stress due to installation position deviation.

[0020] 3. Since the overall position of the conveyor line remains unchanged, a sliding support is installed so that the conveyor line can adaptably slide relative to the sliding support during installation to adjust its position. At the same time, overlapping the conveyor line with the sliding support also releases the internal stress at the sliding support. Attached Figure Description

[0030] 100. Concrete supply point. Detailed Implementation

[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] like Figures 1 to 6 As shown, a fixed feeding conveyor section includes a feeding line 1, and a support system 2 for supporting the feeding line 1 is provided below the feeding line 1. The feeding line mentioned in this application can be the entire feeding conveyor line, directly connected to the concrete supply point 100 and the tower crane, or it can be a section of the entire feeding conveyor line where the height is not raised.

[0033] One end of the conveyor line 1 is hinged to the support system 2, and the other end is slidably connected to the support system 2. The hinged connection enables the conveyor line to be connected to the support system 2, making it difficult for the conveyor line to detach from the support system 2. The other end is slidably connected to the support system 2, so that there is a relative sliding space between the conveyor line and the support system 2, which makes it easy for the conveyor line 1 to be arranged to adapt to different terrains.

[0034] The support system 2 includes multiple support seats 21 located below the conveyor line 1 to support it. The conveyor line 1 specifically comprises multiple truss units 11 assembled sequentially. Each truss unit 11 includes a standard truss 111 and a non-standard truss 112 for adjusting the length of the conveyor line 1. Depending on the specific assembly requirements of each project, the standard truss 111 and non-standard truss 112 are adaptively selected and combined to meet the needs of different lengths and inclination angles. The truss units 11 overlap and are confined to the support seats 21, thereby achieving stable support for the conveyor line 1 from the multiple support seats 21 and restricting the movement path of the conveyor line 1.

[0035] The support base 21 includes a first side support 22 and a second side support 23 located on both sides, and one or more intermediate supports 24 located between the first side support 22 and the second side support 23. The first side support 22 is a base pier 3 or a column 4, the second side support 23 is a base pier 3 or a column 4, and the intermediate support 24 is a base pier 3 or a column 4. The column 4 is suitable for situations with a high support height, specifically using a steel structure column for support; the base pier 3 is suitable for situations with a low support height, and supports the upper material conveyor line 1 by pouring concrete piers on the ground.

[0036] Typically, a rolling support 25 is provided at the top of the first side support 22. One end of the conveyor line 1 is supported on the rolling support 25, which allows for relative sliding of one end of the conveyor line 1. By setting one end of the conveyor line 1 as a flexible end, the conveyor line 1 can be adaptively adjusted in position according to the installation and subsequent operation conditions to meet deformation requirements.

[0037] In the first embodiment, a sliding support 26 is installed on the top of the central support 24. The sliding support 26 includes a base 261 and a limiting support plate 262 rotatably mounted on the base. The base is anchored within the central support 24, and the limiting support plate 262 abuts against the truss unit 11, with a partition layer provided on its surface. Because the sliding support 26 can rotate, the material conveyor line 1 can adaptively adjust its tilt angle according to the terrain. At this time, the limiting support plate 262 rotates adaptively to achieve stable support for the material conveyor line 1.

[0038] A partition is formed on the surface of the sliding support 26, preventing direct contact between the truss unit 11 and the sliding support 26. This reduces wear during relative sliding between the surfaces of the truss unit 11 and the sliding support 26, increasing their service life. In one embodiment, the partition is made of a porous compressible material. The partition increases the resistance to relative sliding between the truss unit 11 and the rotating support. Since the height of the conveyor line 1 does not need to be raised and its position is fixed, the sliding support 26 can provide more stable support for the conveyor line 1. During installation, the conveyor line 1 can also slide relative to the sliding support 26. This first embodiment is suitable for situations where the conveyor line 1 is relatively horizontal and the elevation difference between its various points is small. In this case, the conveyor line 1 bends less, and therefore, the amount of sliding of the conveyor line 1 relative to the sliding support 26 during installation is relatively small. In this case, the support 21 primarily serves to stabilize and support the conveyor line 1.

[0039] In the second embodiment, a rolling support 25 is installed on the top of the central support 24. The rolling support 25 includes a base 261 and a rolling strut 251 rotatably mounted on the base 261. The rolling strut 251 includes several rollers 252 that abut against the bottom of the truss unit 11. By abutting the material conveyor 1 with the rollers 252, the material conveyor 1 can slide more easily relative to the rolling support 25, and thus the position of the material conveyor 1 can be more easily adjusted when it is arranged. This embodiment is applicable to the case where there are multiple inclined sections 12 in the material conveyor 1. There is an elevation difference between the two ends of the inclined section 12, and a rotating mounting point 13 is provided at both ends of the inclined section 12. At the rotating mounting point 13, only the upper chords of two adjacent truss units 11 are rotatably connected, or only the lower chords are rotatably connected, thereby realizing the relative rotation of two adjacent truss units 11.

[0040] At this time, when installing the material conveyor line 1, first install the end that is hinged to the support system 2, and then assemble the truss unit 11 in sequence towards the side that is slidably connected to the support system 2. Since the truss unit 11 is slidably connected to the rolling support 25, the truss unit 11 can adaptively adjust its position, reducing the difficulty of assembly and positioning. At the same time, the rolling support plate 251 is rotatably connected to the foundation 261, so that the rolling support 25 can adaptively adjust its angle according to the inclination of the material conveyor line 1.

[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.
