DETAILED DESCRIPTION

[0031] The technical solutions in the embodiments of the present application will be described clearly and completely below with reference to the drawings in the embodiments of the present application. Obviously, the described embodiments are only some of the embodiments of the present application, but not all the embodiments. Based on the embodiments in the present application, all other embodiments obtained by those skilled in the art without creative work fall within the scope of protection of the present application.

[0032] As Figure 1As shown, in the construction of the inverted siphon, first, the excavation and treatment of the foundation pit 200 are carried out, then the pouring of the abutment 300 and the buttress 400 and the laying of the inverted siphon pipe 500 are carried out, and finally, the pouring of the foundation pit 200 is carried out. When pouring the foundation pit 200, due to the relatively thick inverted siphon pipe 500, and the heavy hose when pumping concrete by the pump truck 100, the staff cannot stretch the hose below the inverted siphon pipe 500, making it difficult to discharge the concrete below the inverted siphon pipe 500, which can only be handled subsequently by the staff. Based on this, the following technical scheme is proposed.

[0033] Referring to the drawings Figures 1-9 A high-long-distance concrete conveying device for inverted siphon construction, comprising two groups of conveying units 1, the conveying unit 1 comprising a self-walking frame 2, the self-walking frame 2 being used to move along the concrete pouring route, a mounting plate 21 being fixedly installed on the self-walking frame 2, a fixed frame 3 being fixedly installed on the mounting plate 21, a mudguard 4 being slidingly installed on the fixed frame 3, the lower end of the mudguard 4 being located at the bottom of the fixed frame 3, a driving assembly 5 being installed on the fixed frame 3, the driving assembly 5 being used to drive the mudguard 4 to move along the length direction of the fixed frame 3, a spray pipe 6 being fixedly installed at the bottom of the self-walking frame 2, the discharge opening of the spray pipe 6 facing the mudguard 4, the concrete being sprayed out of the discharge opening of the spray pipe 6 and hitting the surface of the mudguard 4.

[0034] As Figure 1 shown in the above technical scheme, the concrete conveying device further comprises a pump truck 100, the pump truck 100 being used to convey concrete to the spray pipes 6 on the two conveying units 1 through the shunt pipe 9, one side of the spray pipe 6 being provided with an air inlet 61, the air inlet 61 being connected with an air flow sprayer.

[0035] It should be noted that when conveying concrete, the concrete is discharged from the discharge opening of the spray pipe 6, the air flow sprayer sprays compressed air, the compressed air carries the concrete and sprays it out quickly, hitting the surface of the mudguard 4.

[0036] As Figures 5-9 shown in the above technical scheme, the driving assembly 5 comprises a power component one 51, a driving rod one 52 and a driving rod two 53, the power component one 51 being installed at one end of the fixed frame 3 close to the self-walking frame 2, one end of the driving rod one 52 being installed at the output end of the power component one 51, so that the power component one 51 drives the driving rod one 52 to swing, one end of the driving rod two 53 being installed at the upper end of the mudguard 4, the mutually close ends of the driving rod one 52 and the driving rod two 53 being hinged.

[0037] Furthermore, the drive assembly 5 also includes a first connector 54 and a second connector 55. The first connector 54 is fixedly installed at the output end of the first power component 51, and the end of the first drive rod 52 is fixedly installed at the bottom end of the first connector 54. The output shaft of the first power component 51 is perpendicular to the axis of the first drive rod 52. The second connector 55 is rotatably installed at the upper end of the mudguard 4. One end of the second drive rod 53 is fixedly installed at the upper end of the second connector 55, and the axis of the second drive rod 53 is perpendicular to the rotation axis of the second connector 55.

[0038] It should be noted that the power component 51 is a geared motor. The output shaft of the power component 51 is parallel to the rotation axis of the connecting piece 55. The power component 51 drives the drive rod 52 to rotate through the connecting piece 54. The drive rod 52 drives the mudguard 4 to slide on the fixed frame 3 through the drive rod 53 and the connecting piece 54, thereby changing the position of the mudguard 4 on the fixed frame 3.

[0039] In the above technical solution, the self-propelled frame 2 is equipped with a motor and traveling wheels, and the traveling wheels are driven to move by the motor.

[0040] In this embodiment, the specific implementation method is as follows: during construction, such as Figure 1 As shown, the device is placed in a suitable position and moved by the self-propelled frame 2. When pouring concrete, the drive assembly 5 first moves the mudguard 4 to the farthest position, which is the middle of the pit 200. Then, the pump truck 100 supplies concrete to the nozzle 6. The concrete is sprayed from the outlet of the nozzle 6 onto the mudguard 4, hitting the surface of the mudguard 4. The concrete then falls down and into the middle of the pit 200. During the concrete conveying process, the drive assembly 5 slowly moves the mudguard 4 towards the edge of the pit 200, so that the concrete is gradually poured from the middle of the pit 200 to the edge. When the mudguard 4 moves to the position closest to the edge of the pit 200, the self-propelled frame 2 moves the conveying unit 1 forward a certain distance, and the drive assembly 5 moves the mudguard 4 back to the middle of the pit 200. The above pouring process is repeated.

[0041] The above technical solution delivers concrete into the bottom of the inverted siphon 500 by concrete spraying. By setting a mudguard 4, the concrete spray hits the surface of the mudguard 4 and then falls down to control the concrete pouring position. The drive component 5 drives the mudguard 4 to move back and forth, thereby realizing the concrete pouring function from the middle to the edge of the foundation pit 200. Compared with the existing technology, it is no longer necessary to manually hold the hose and extend it under the inverted siphon 500 to achieve pouring.

[0042] Refer to the instruction manual appendix Figures 1-9The fixed frame 3 comprises two side support frames 31 arranged side by side, one end of each of the two side support frames 31 is fixedly installed on the mounting plate 21, and the side of each of the two side support frames 31 close to each other is fixedly installed with an inner support plate 32, the upper end of the mudguard 4 is arranged between the two inner support plates 32, and the two sides of the upper end of the mudguard 4 are respectively arranged in abutment with the side walls of the two inner support plates 32.

[0043] It should be noted that the two sides of the mudguard 4 are limited by the two inner support plates 32, so that the mudguard 4 can move along the length direction of the inner support plate 32.

[0044] During the concrete pouring process, the length of the fixed frame 3 cannot be extended to the middle of the foundation pit 200 due to the obstruction of the pier 400, so as to avoid collision with the pier 400, but at this time, the mudguard 4 cannot be moved to the middle of the foundation pit 200, in order to make the concrete in the middle of the foundation pit 200 not be affected by the existence of the pier 400 during pouring, specifically, the end of the fixed frame 3 away from the self-propelled frame 2 is provided with a range increasing assembly 7, the range increasing assembly 7 comprises a front plate 71, both ends of the front plate 71 are fixedly installed with guide rods 73, one end of each of the two guide rods 73 away from the front plate 71 is fixedly installed with a sliding block 75, the two sliding blocks 75 are respectively slidably arranged in the inner part of the side support frame 31, the outer side of the guide rod 73 is sleeved with an elastic component 74, and both ends of the elastic component 74 are respectively in pressure combination with the sliding block 75 and the end of the front plate 71.

[0045] Further, both ends of the front plate 71 close to the side of the mudguard 4 are provided with two clamping plates 72, the two clamping plates 72 are arranged in opposite positions and one end of each of the two clamping plates 72 is fixedly connected with the front plate 71, the two clamping plates 72 are respectively located on the upper surface and the lower surface of the inner support plate 32, and the side wall of the clamping plate 72 coincides with the side wall of the inner support plate 32.

[0046] In the above technical solution, the range increasing assembly 7 is arranged to increase the stroke of the mudguard 4, in the initial state, the front plate 71 is in abutment with the inner support plate 32, and the two clamping plates 72 are in abutment with the inner support plate 32, so that the mudguard 4 is in abutment with the inner support plate 32. Figure 6As shown, the range extender 7 is attached to the end of the side support frame 31. When it does not encounter the support pier 400, the drive component 5 drives the mudguard 4 to move forward. When the mudguard 4 contacts the front plate 71, it continues to move and pushes the front plate 71 forward. At this time, the upper end of the mudguard 4 is located between the clamping plates 72 on both sides of the front plate 71, ensuring that the mudguard 4 can only move along the length direction of the fixed frame 3. The two clamping plates 72 set above and below slide on the upper and lower surfaces of the inner support plate 32 respectively to improve the stability of the front plate 71 when it moves. By extending the front plate 71, the travel of the mudguard 4 is lengthened, so that the mudguard 4 can move to the middle of the pit 200 and pour concrete at the middle position of the pit 200. When encountering the support 400 during concrete pouring, simply use the drive assembly 5 to drive the mudguard 4 forward, so that the mudguard 4 moves to the end of the support 400. From this position, concrete can be poured towards the edge of the pit 200. The area occupied by the support 400 does not need to be poured.

[0047] Refer to the instruction manual appendix Figures 1-7 and Figure 9 Two sets of conveying units 1 are set up so that both sides of the foundation pit 200 can be poured at the same time. An avoidance component 8 is set between the two conveying units 1. The purpose is to connect the two conveying units 1 to improve stability and to avoid the support 400. Specifically, the avoidance component 8 includes two arc-shaped pipes 81. The two arc-shaped pipes 81 are respectively fixedly installed at the close ends of the fixing frames 3 of the two conveying units 1. A second power component 83 is installed on each of the two fixing frames 3. The same arc-shaped connector 82 is slidably arranged inside the two arc-shaped pipes 81. The two second power components 83 are used to drive the arc-shaped connector 82 to slide inside the arc-shaped pipes 81.

[0048] Furthermore, gears 84 are fixedly installed at the output ends of both power components 83, and several gear teeth 821 are opened on the outer side of the arc-shaped connector 82. The side wall of the arc-shaped tube 81 has an opening, and the gears 84 mesh with the gear teeth 821 at the opening position.

[0049] like Figure 2As shown, under normal circumstances, the arc-shaped connector 82 is located inside both arc-shaped pipes 81, and the two arc-shaped pipes 81 are respectively fixed on the fixing frame 3 of the two conveying units 1. Thus, the two conveying units 1 are connected and supported by the arc-shaped connector 82. When pouring concrete, the opening of the arc-shaped connector 82 faces the side of the support 400. When encountering the support 400, and during the movement, when the support 400 is located in the middle of the arc-shaped connector 82, the power component 83 drives the arc-shaped connector 82 to move inside the two arc-shaped pipes 81 through the meshing of the gear 84 and the gear tooth 821. After one end of the arc-shaped connector 82 enters the interior of one of the arc-shaped pipes 81, the other end of the arc-shaped connector 82 moves out from the other end of this arc-shaped pipe 81, as shown. Figure 2 As shown, this allows the arc-shaped connector 82 to rotate to the front of the support 400. After the concrete at the support 400 is poured, the arc-shaped connector 82 is rotated back by the second power component 83, so that the opening of the arc-shaped connector 82 faces the next support 400. The second power component 83 is a motor.

[0050] Refer to the instruction manual appendix Figures 1-2 The conveying unit 1 also includes a track 20, which is arranged along the length of the slope 201 and is used to support the self-propelled frame 2, thereby allowing the self-propelled frame 2 to move on the track 20.

[0051] It should be noted that during use, the track 20 is installed on the slope 201. By setting the track 20, the stability of the self-propelled frame 2 can be improved, so that the length direction of the fixed frame 3 can always be consistent with the width direction of the pit 200.

[0052] This concrete conveying device is suitable for pouring concrete in the foundation pit during the construction of an inverted siphon, and is especially suitable for pouring concrete on the steep slope of a long and high foundation pit where it is inconvenient for personnel to stand.

[0053] In conclusion, the above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present invention should be included within the protection scope of the present invention.
