Description

Technical Field

[0001] This utility model belongs to the field of concrete conveying technology, and in particular relates to a concrete conveying device. Background Technology

[0002] Belt conveyors can quickly transport concrete from the batching plant or concrete trucks to the pouring site, reducing waiting time during transportation, ensuring the quality of concrete pouring, and improving construction efficiency. Furthermore, belt conveyors can be flexibly deployed according to the terrain and construction requirements of the site, adapting to different construction conditions, and enabling long-distance transportation, thus reducing the cost of manpower and other transportation equipment.

[0003] In the existing technology, some belt conveyors use inclined belts to transport concrete to higher places. Although the inclined belt can increase the transport height of the concrete, the connection between the inclined belt and the horizontal belt is not good, which can easily lead to concrete spillage. Moreover, the horizontal transport distance of belt conveyors is mostly fixed and cannot be adjusted according to the actual construction conditions.

[0004] Therefore, designing a concrete conveying device that can flexibly adjust the concrete transport distance, or that can smoothly transition concrete from inclined transport to horizontal transport, is of great significance for concrete transportation. Utility Model Content

Those skilled in the art can understand the specific meaning of the above terms in this utility model based on the specific circumstances.

[0043] As attached Figures 1-3 As shown in an illustrative embodiment of the concrete conveying device of this utility model, the concrete conveying device includes a truss 4, a first belt assembly 1, a second belt assembly 2, a third belt assembly 3, and a drive assembly; the truss 4 is arranged horizontally; a hopper 9 is provided at one end of the length direction of the truss 4, the hopper 9 has a feed inlet on its circumference and a discharge outlet at its bottom; the first belt assembly 1 is inclined upwards for conveying concrete upwards; the upper end of the first belt assembly 1 is located at the feed inlet; the second belt assembly 2 is arranged horizontally and is installed on the truss 4; one end of the second belt assembly 2 is located below the discharge outlet, and the other end of the second belt assembly 2 is arranged away from the hopper 9 for conveying concrete away from the hopper 9; the third belt assembly 3 is arranged in the same direction as the second belt assembly 2 and is located below the second belt assembly 2; the third belt assembly 3 is placed on the truss 4; the drive assembly is used to drive the third belt assembly 3 to reciprocate linearly along the setting direction of the third belt assembly 3 to adjust the horizontal conveying distance of the concrete.

[0044] The aforementioned concrete conveying device achieves upward conveying of concrete by setting a first belt assembly 1 at an upward angle, thereby increasing the conveying height of the concrete; it achieves horizontal conveying of concrete by setting a second belt assembly 2 horizontally; it achieves horizontal conveying of concrete by setting a third belt assembly 3 in the same direction as the second belt assembly 2, and a drive assembly drives the third belt assembly 3 to reciprocate linearly along its setting direction, thereby adjusting the horizontal conveying distance of the concrete; and it achieves a smooth transition of concrete between the first belt assembly 1 and the second belt assembly 2 by setting a hopper 9 on the truss 4, with the upper end of the first belt assembly 1 located at the inlet of the hopper 9 and the second belt assembly 2 located below the outlet of the hopper 9.

[0045] like Figure 2 As shown, the hopper 9 is rotatably connected to the truss 4. The hopper 9 rotates in the vertical direction so that the orientation of the feed inlet can be adjusted, thereby allowing the first belt assembly 1 to be placed in a position according to the working conditions of the construction site, making it easier for the concrete conveying device to adapt to various sites.

[0046] like Figure 1 As shown, a movable wheel 11 is installed at the lower end of the first belt assembly 1. The movable wheel 11 is in contact with the ground and is used to drive the lower end of the first belt assembly 1 to move. When the hopper 9 rotates, the position of the first belt assembly 1 also changes with the position of the feed inlet. The movable wheel 11 installed at the lower end of the first belt assembly 1 facilitates the movement of the first belt assembly 1.

[0047] like Figure 2 As shown, the first belt assembly 1 includes a first mounting frame 14, a first rotating roller 13, a first idler roller 12, a first belt, and a first motor. The first mounting frame 14 is inclined upward. The first rotating roller 13 and the first idler roller 12 are mounted on the first mounting frame 14. The first rotating roller 13 drives the first belt to rotate, and the first idler roller 12 supports the rotation of the first belt. The first rotating roller 13 and the first idler roller 12 are arranged along the setting direction of the first belt assembly 1. The first belt is wrapped around the outer periphery of the first rotating roller 13 and the first idler roller 12. The inner surface of the first belt is in contact with the outer peripheral wall of the first rotating roller 13 and the first idler roller 12. The first motor drives the first rotating roller 13 to rotate, so that the first rotating roller 13 drives the first belt to rotate.

[0048] It should be noted that when the first belt conveys concrete, the concrete will exert pressure on the first belt, causing the first belt to bend downwards. This will not only affect the conveying of the first belt, but also easily damage the first belt. By setting the first idler 12, the first idler 12 supports the first belt, ensuring the reliability of the rotation of the first belt.

[0049] It should also be noted that there are usually two first rollers 13, which are respectively located at the two ends of the first belt. The first motor drives one of the first rollers 13 to rotate, and the other first roller 13 is used to support the first belt and change the rotation direction of the first belt. There are multiple first idlers 12, which are arranged along the setting direction of the first belt assembly 1 and located between the two first rollers 13.

[0050] It should also be noted that the upper end of the first belt is located at the feed inlet, and the lower end of the first belt is located at the concrete transport vehicle 7, which is used to transfer the concrete transported in the concrete transport vehicle 7 to the hopper 9.

[0051] In addition, it should be noted that the movable wheel 11 is located at the lower end of the first mounting frame 14, and the movable wheel 11 is located on the side of the first mounting frame 14 away from the concrete transport vehicle 7.

[0052] like Figure 2 and Figure 3 As shown, the second belt assembly 2 includes a second mounting frame 24, a second rotating roller 21, a second idler roller 22, a second belt 23, and a second motor. The second mounting frame 24 is arranged in a horizontal direction. The second rotating roller 21 and the second idler roller 22 are mounted on the second mounting frame 24 and arranged in the direction of the second belt assembly 2. The second belt 23 is wound around the outer periphery of the second rotating roller 21 and the second idler roller 22, and the inner surface of the second belt 23 is in contact with the outer periphery of the second rotating roller 21 and the second idler roller 22. The second rotating roller 21 is used to drive the second belt 23 to rotate, the second idler roller 22 is used to support the rotation of the second belt 23, and the second motor drives the second rotating roller 21 to rotate so that the second rotating roller 21 drives the second belt 23 to rotate.

[0053] It should be noted that when the second belt 23 conveys concrete, the concrete will exert pressure on the second belt 23, causing the second belt 23 to bend downwards. This will not only affect the conveying of the second belt 23, but also easily damage the second belt 23. By setting the second idler 22, the second idler 22 supports the second belt 23, ensuring the reliability of the rotation of the second belt 23.

[0054] It should also be noted that there are usually two second rollers 21, which are respectively located at the two ends of the second belt 23. The second motor drives one of the second rollers 21 to rotate, and the other second roller 21 is used to support the second belt 23 and change the rotation direction of the second belt 23. There are multiple second idlers 22, which are arranged along the setting direction of the second belt assembly 2, and the multiple second idlers 22 are located between the two second rollers 21.

[0055] like Figure 3As shown, the second mounting bracket 24 is also equipped with a tension roller 25, which is located below the second belt 23. The second belt 23 is arranged to pass around the tension roller 25, and the outer surface of the second belt 23 is in contact with the top peripheral wall of the tension roller 25. The tension roller 25 is used to tension the second belt 23. It should be noted that when the second belt 23 passes through the tension roller 25, the tension roller 25 can also clean the concrete residue on the surface of the second belt 23.

[0056] It should be noted that the first mounting frame 14 is also equipped with a tension roller 25, which is located below the first belt. The first belt passes around the tension roller 25, and the outer surface of the first belt is in contact with the top peripheral wall of the tension roller 25. The tension roller 25 is used to tension the first belt. It should also be noted that when the first belt passes through the tension roller 25, the tension roller 25 can also clean the concrete residue on the surface of the first belt.

[0057] The third belt assembly 3 and the second belt assembly 2 are set independently to facilitate the disassembly and maintenance of the third belt assembly 3 or the second belt assembly 2.

[0058] like Figure 1 As shown, the end of the third belt assembly 3 away from the hopper 9 is provided with a discharge cylinder 8, which is used to guide the concrete to fall. Since the position of the third belt assembly 3 changes under the action of the drive assembly, the position of the discharge cylinder 8 also changes. In order to prevent the truss 4 from interfering with the operation of the discharge cylinder 8, in this application, the truss 4 is designed as a frame structure so that the discharge cylinder 8 can pass through the truss 4.

[0059] In some embodiments, the truss 4 has a cavity inside, which is arranged along the direction of the truss 4; the top of the truss 4 has an opening; and the truss 4 has a U-shaped frame structure.

[0060] like Figure 2 and Figure 3 As shown, the third belt assembly 3 includes a third mounting frame 32, a third rotating roller 31, a third idler roller 33, a third belt 34, and a third motor; the third mounting frame 32 is arranged in a horizontal direction; the third rotating roller 31 and the third idler roller 33 are mounted on the third mounting frame 32 and arranged in the direction of the third belt assembly 3; the third belt 34 is wound around the outer periphery of the third rotating roller 31 and the third idler roller 33, and the inner surface of the third belt 34 is in contact with the outer peripheral wall of the third rotating roller 31 and the third idler roller 33; the third rotating roller 31 is used to drive the third belt 34 to rotate, the third idler roller 33 is used to support the rotation of the third belt 34, and the third motor drives the third rotating roller 31 to rotate, thereby driving the third belt 34 to rotate.

[0061] It should be noted that the feed cylinder 8 is installed on the third mounting frame 32 and located at the end of the third belt 34 away from the hopper 9.

[0062] When the third belt 34 conveys concrete, the concrete will exert pressure on the third belt 34. By setting the third idler 33, the third idler 33 supports the third belt 34, ensuring the reliability of the rotation of the third belt 34.

[0063] It should also be noted that there are usually two third rollers 31, which are located at the two ends of the third belt 34 respectively. The third motor drives one of the third rollers 31 to rotate. The third roller 31 is used to support the third belt 34 and change the rotation direction of the third belt 34. There are multiple third rollers 33, which are arranged along the setting direction of the third belt assembly 3 and are located between the two third rollers 31.

[0064] like Figure 3 As shown, the third mounting bracket 32 ​​is also equipped with a tension roller 25, which is located below the third belt 34. The third belt 34 is arranged to pass around the tension roller 25, and the outer surface of the third belt 34 is in contact with the top peripheral wall of the tension roller 25. The tension roller 25 is used to tension the third belt 34. It should be noted that when the third belt 34 passes through the tension roller 25, the tension roller 25 can also clean the concrete residue on the surface of the third belt 34.

[0065] like Figure 4 As shown, the drive assembly includes a drive wheel 35 and a drive motor 36. The drive wheel 35 is mounted on the bottom of the third mounting bracket 32 ​​and is used to drive the third mounting bracket 32 ​​to move horizontally. The drive motor 36 is used to drive the drive wheel 35 to rotate.

[0066] It should be noted that there are multiple drive wheels 35, which are arranged along the direction of the third mounting bracket 32.

[0067] For ease of description, in this embodiment, the movement of the third belt assembly 3 away from the hopper 9 driven by the drive assembly is referred to as the extension of the third belt assembly 3, and the movement of the third belt assembly 3 towards the hopper 9 driven by the drive assembly is referred to as the contraction of the third belt assembly 3.

[0068] It should be noted that at least part of the third belt 34 is located directly below the second belt 23 so that the concrete on the second belt 23 falls onto the third belt 34 under the action of gravity. If there is a gap in the horizontal direction between the second belt 23 and the third belt 34, the concrete on the second belt 23 can easily fall into the gap, resulting in concrete waste.

[0069] In some embodiments, the truss 4 is provided with a limiting member to limit the extension distance of the third mounting bracket 32 ​​and prevent a gap in the horizontal direction between the second belt 23 and the third belt 34.

[0070] In some embodiments, the length of the second belt 23 is 10m, the effective length of the third belt 34 is 8m, and the maximum distance that the concrete conveying device can convey concrete in the horizontal direction is 18m.

[0071] like Figure 5 As shown, the concrete conveying device also includes a workbench 6, which is used to fix the truss 4 to increase the stability and reliability of the second belt assembly 2 and the third belt assembly 3.

[0072] In some embodiments, such as Figure 1 As shown, the bottom of the truss 4 is provided with two connecting parts, which are arranged along the length of the truss 4; the workbench 6 is connected to the telescopic rod 61, and the fixed end of the telescopic rod 61 is installed on the workbench 6; the connecting part near the hopper 9 is rotatably connected to the top of the workbench 6, and the other connecting part is rotatably connected to the telescopic end of the telescopic rod 61.

[0073] like Figure 5 As shown, the workbench 6 is connected to a rotating shaft 62. The workbench 6 rotates vertically via the rotating shaft 62 to drive the truss 4 and the first belt assembly 1, the second belt assembly 2 and the third belt assembly 3 to rotate, thereby adjusting the direction of concrete transport and increasing the working space and flexibility of the concrete conveying device so that it can adapt to various environments.

[0074] like Figure 5 As shown, the workbench 6 is equipped with a counterweight 64. The counterweight 64 is used to increase the weight of the workbench 6, ensure the stability of the third belt assembly 3 during movement, and avoid instability of the center of gravity of the concrete conveying device due to the elongation of the third belt assembly 3.

[0075] In some embodiments, the counterweight weighs 5t.

[0076] like Figure 5 As shown, the workbench 6 is equipped with a control box 63, which is used to control the operation of the first motor, the second motor, the third motor and the drive motor 36.

[0077] In some embodiments, the control panel of the control box 63 is as follows: Figure 6 As shown, the operation panel is common knowledge in this field and will not be described in detail.

[0078] like Figure 1 and Figure 7 As shown, the concrete conveying device also includes a chassis 5, which is used to mount the workbench 6; the chassis 5 is connected to a lifting assembly 52, which is used to raise or lower the height of the chassis 5 in the vertical direction.

[0079] In some embodiments, the lifting assembly 52 is a hydraulic cylinder that extends and retracts in a vertical direction. By extending and retracting the hydraulic cylinder, the height of the chassis 5 is adjusted, thereby adjusting the height of the first belt assembly 1 and the second belt assembly 2, so that the concrete conveying device can better adapt to the height of the component to meet the requirements of concrete pouring.

[0080] In this embodiment, four lifting components 52 are provided to increase the stability of the entire chassis 5.

[0081] like Figure 7 As shown, the chassis 5 is equipped with a traveling wheel 51, which is located at the bottom of the chassis 5 and is used to drive the chassis 5 to move.

[0082] In some embodiments, the chassis 5 is modified from the chassis 5 of a 25t crane, which retains the hydraulic system, support cylinders and outriggers, ensuring the stability and safety of the concrete conveying device.

[0083] It should be noted that in practical applications, the first belt, the second belt 23, and the third belt 34 should be kept at the same frequency as much as possible in order to reduce belt wear caused by speed difference.

[0084] The working principle of the above-mentioned concrete conveying device is as follows: The concrete transport vehicle 7 transports concrete to the designated location. The first motor drives the first rotating roller 13 to rotate, causing the first belt to convey the concrete transported by the concrete transport vehicle 7 upward to the hopper 9. The concrete conveyed by the first belt enters the hopper 9 through the inlet and falls onto the second belt 23 under the action of gravity. The second motor drives the second rotating roller 21 to rotate, and the second belt 23 conveys the concrete falling onto the second belt 23 in a direction away from the hopper 9. When the distance that the concrete needs to be conveyed is long, the length of the second belt 23 cannot meet the horizontal conveying requirements of the concrete. The drive motor 36 drives the drive wheel 35 to rotate, causing the drive wheel 35 to drive the second belt 21 to rotate. The three mounting brackets 32 move away from the hopper 9, causing the third belt 34 to extend beyond the second belt 23, and positioning the end of the third belt 34 away from the hopper 9 above the designated position. When the concrete on the second belt 23 is transported to the end of the second belt 23 away from the hopper 9, the concrete will fall onto the third belt 34 under gravity. The third motor drives the third roller 31 to rotate, causing the third belt 34 to continue conveying concrete away from the hopper 9 until the concrete is transported above the designated position. After the concrete is transported above the designated position by the third belt 34, it falls into the discharge cylinder 8 under gravity. The concrete falls to the designated position under the constraint or guidance of the discharge cylinder 8.

[0085] The aforementioned concrete conveying device can not only transport concrete vertically, but also horizontally, and the horizontal conveying distance can be adjusted; moreover, during the conveying process, the concrete transitions smoothly from the vertical to the horizontal direction.

[0086] Finally, it should be noted that the various embodiments in this specification are described in a progressive manner, with each embodiment focusing on the differences from other embodiments. The same or similar parts between the various embodiments can be referred to each other.

[0087] The above embodiments are only used to illustrate the technical solution of this utility model and not to limit it; although the utility model has been described in detail with reference to preferred embodiments, those skilled in the art should understand that modifications can still be made to the specific implementation of this utility model or equivalent substitutions can be made to some technical features without departing from the spirit of the technical solution of this utility model, and all such modifications and substitutions should be covered within the scope of the technical solution claimed by this utility model.
