Description

Technical Field

[0001] This utility model belongs to the technical field of concrete conveying equipment, and specifically relates to a support structure for a tower belt conveyor feeding line. 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] The concrete conveyor line needs to be raised as the dam is poured. Therefore, the concrete conveyor line needs to be constantly adjusted in angle during the pouring process to meet the pouring requirements at different heights. As the concrete conveyor line is raised, the height and angle between the conveyor line and the supporting structure below need to be adjusted. Therefore, a supporting structure is needed that can stably support the concrete conveyor line while also meeting the requirements for adjusting the height and angle of the concrete conveyor line. Utility Model Content

[0004] This utility model provides a support structure for a tower belt conveyor feeding line to solve the problem of adaptive adjustment of the height and angle of the concrete conveyor line.

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

[0006] A support structure for a tower conveyor feeding line includes multiple spaced columns and a feed line for conveying concrete, which is erected on the columns. Some of the columns are equipped with climbing frames, and the top surfaces of the climbing frames and some of the columns are equipped with rolling supports. Some of the columns are equipped with rotating supports. The feed line overlaps the rolling supports and the rotating supports, and the feed line slides relative to the rolling supports.

[0007] Furthermore, the rolling support includes a first base and a roller support plate, the roller support plate being rotatably connected to the first base, and the first base being installed on the top surface of the column or the climbing frame;

[0008] The feeding line includes a structural truss, the roller support plate is supported below the structural truss, and the sliding limit of the structural truss is located within the roller support plate.

[0009] Furthermore, the roller support plate includes a first row of rollers and a second row of rollers, both of which include a plurality of rollers arranged at intervals to support the structural truss.

[0010] Furthermore, a limiting annular groove is formed on the surface of the roller, the limiting annular groove is arranged circumferentially along the surface of the roller, and the lower chord of the structural truss is engaged in the limiting annular groove.

[0011] Furthermore, both the first wheel row and the second wheel row include a first support plate and a second support plate arranged in parallel at intervals. A plurality of rollers are installed between the first support plate and the second support plate, and the rollers are fixedly sleeved on the outside of the rollers and located between the first support plate and the second support plate.

[0012] Furthermore, the first base includes a supporting vertical cylinder and a supporting horizontal bar, the supporting horizontal bar is fixedly installed on the top of the supporting vertical cylinder, and the first wheel row and the second wheel row are symmetrically arranged on both sides of the supporting horizontal bar along the supporting vertical cylinder.

[0013] Furthermore, the rotating support includes a second base, which has the same structure as the first base. A first support and a second support are symmetrically arranged on the second base. Both the first support and the second support are rotatably connected to the second base. The feeding line overlaps and is confined between the first support and the second support.

[0014] Furthermore, both the first support and the second support include a support plate for contacting the structural truss, and the area of ​​the support plate in contact with the structural truss is formed with an L-shaped groove.

[0015] Furthermore, the surface of the L-shaped groove is provided with a spacer for isolating the feed line and the support plate surface.

[0016] Furthermore, the cross-sectional shapes of the limiting annular groove and the L-shaped groove are consistent, and they partially match the cross-sectional shape of the lower chord of the structural truss.

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

[0018] 1. A climbing frame is installed on the column. The lifting and lowering of the climbing frame can drive the feeding line to rise and fall. If the height of the two ends of multiple feeding lines changes, the relative angle between the feeding line and the column will also change. Rolling supports and rotating supports are set on the top surface of the climbing frame and the column, which can stably support the feeding line and meet the rotation and movement requirements of the feeding line.

[0019] 2. A limiting ring groove is set on the surface of the roller. The structural truss part of the feeding line is engaged in the limiting ring groove. The limiting ring groove can restrict the movement path of the feeding line and make the feeding line slide in the installation direction. Moreover, the setting of the roller reduces the sliding resistance of the feeding line relative to the rolling support.

[0020] 3. The rotating support includes a second base, and a first support and a second support are rotatably mounted on the second base; the rolling support includes a first base and a roller support plate, so that both the rotating support and the rolling support can meet the rotation requirements.

[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 Figures 1 to 6As shown, a support structure for a tower conveyor feeding line includes multiple spaced columns 1 and a feeding line 2 erected on the columns 1 for conveying concrete. Some columns 1 are equipped with climbing frames 3 that can climb along the columns 1. The climbing frames 3 climb and drive the height of some points on the feeding line 2 to rise, thereby adjusting the inclination and overall height of the feeding line 2 to meet the concrete transportation needs at different elevations.

[0032] To facilitate the smooth lifting of the feeding line 2, the feeding line 2 and the column 1 need to be rotated and slidably connected. Therefore, rolling supports 4 are installed on the top surface of the climbing frame 3 and part of the column 1, and rotating supports 5 are installed on the top surface of part of the column 1. The feeding line 2 overlaps on the rolling supports 4 and the rotating supports 5. The parts of the rolling supports 4 and the rotating supports 5 that are in contact with the feeding line 2 rotate relative to the column 1, and the feeding line 2 slides relative to the rolling supports 4 and also slides relative to the rotating supports 5.

[0033] Specifically, the rolling support 4 includes a first base 41 and a roller support plate. The roller support plate is rotatably connected to the first base 41, and the first base 41 is fixedly installed on the top surface of the column 1 or the climbing frame 3. The roller support plate includes a first wheel row 42 and a second wheel row 43. Both the first wheel row 42 and the second wheel row 43 include several rollers 44 arranged at intervals to support the feeding line 2. Using the rollers 44 to support the feeding line 2 can reduce the resistance to relative movement between the feeding line 2 and the rolling support 4, thereby meeting the displacement requirements during the height lifting process of the feeding line 2.

[0034] Furthermore, a limiting annular groove 441 is formed on the surface of the roller 44. The limiting annular groove 441 is arranged circumferentially along the surface of the roller 44. The feeding line 2 includes a structural truss 21, and the lower chord of the structural truss 21 is engaged in the limiting annular groove 441. By setting the limiting annular groove 441, the movement path of the feeding line 2 can be restricted, making it less prone to deviation during sliding and reducing movement resistance. Among them, the first wheel row 42 and the second wheel row 43 respectively support the two lower chords of the feeding line 2, thereby making the support of the rolling support 4 more stable and reliable.

[0035] Both the first row 42 and the second row 43 include a first support plate 421 and a second support plate 422 arranged in parallel at intervals. Several rollers 45 are installed between the first support plate 421 and the second support plate 422. Rollers 44 are fixedly sleeved on the outside of the rollers 45 and positioned between the first support plate 421 and the second support plate 422. Part of the rollers 44 protrudes from the surfaces of the first support plate 421 and the second support plate 422, thus providing support for the feed line 2. The arrangement of the first support plate 421 and the second support plate 422, along with the multiple rollers 45, enhances the load-bearing capacity of the rolling support 4, ensuring that the rolling support 4 remains structurally stable and reliable while supporting the upper feed line 2 and the concrete transported on it.

[0036] The first base 41 includes a supporting vertical cylinder 411 and a supporting horizontal bar 412. The supporting horizontal bar 412 is fixedly installed on the top of the supporting vertical cylinder 411, and the first wheel row 42 and the second wheel row 43 are symmetrically arranged on both sides of the supporting horizontal bar 412 along the supporting vertical cylinder 411. Most sections of the supporting vertical cylinder 411, which is installed on the rolling support 4 at the top of the column 1, is anchored inside the column 1. The supporting vertical cylinder 411 of the rolling support 4, which is installed on the climbing frame 3, passes through the climbing frame 3 and is anchored to the climbing frame 3.

[0037] The rotating support 5 includes a second base 51, which has the same structure as the first base 41. A first support 52 and a second support 53 are symmetrically arranged on the second base 51 along the supporting vertical cylinder 411. The first support 52 and the second support 53 are rotatably connected to the supporting horizontal bar 412 of the second base 51. The first support 52 and the second support 53 both include a support plate 54 for contacting the structural truss 21. The area where the support plate 54 contacts the structural truss 21 forms an L-shaped groove 541. The L-shaped grooves 541 on the first support 52 and the second support 53 are arranged opposite to each other. The feeding line 2 is connected between the first support 52 and the second support 53. The relative L-shaped grooves 541 can limit the movement of the structural truss 21, making it difficult for the structural truss 21 to detach from the rotating support 5 during movement.

[0038] It should be noted that both the first base 41 and the second base 51 have two design forms. Figure 5 The first design of the first base 41 and the second base 51 is shown. Figure 6 The second design of the first base 41 and the second base 51 is shown. The first design is used to install the rolling support 4 and the rotating support 5 on the top of the column 1 and the climbing frame 3, while the second design is used to install the rolling support 4 and the rotating support 5 inside the concrete pier column.

[0039] Furthermore, the surface of the L-shaped groove 541 is provided with a spacer 542 for isolating the feeding line 2 and the support plate 54. Since the feeding section may slide relative to the rotating support 5 during the installation process, the spacer 542 prevents the feeding line 2 and the support plate 54 from directly contacting each other, thereby reducing the sliding and wear between the feeding line 2 and the support plate 54.

[0040] It should be noted that the cross-sectional shapes of the limiting ring groove 441 and the L-shaped groove 541 are consistent and partially match the cross-sectional shape of the lower chord of the structural truss 21. When the lower chord of the structural truss 21 is inserted into the limiting ring groove 441 or the L-shaped groove, it can be precisely engaged, reducing the horizontal movement allowance of the structural truss 21.

[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.
