Description

Technical Field

[0001] The invention relates to the technical field of building construction, and more specifically to a high-long-distance concrete conveying device for inverted siphon construction. Background Art

[0002] An inverted siphon is a structure that needs to be built when the channel and the road or ditch are close in elevation and intersecting in plane, so that water can pass through the road surface or ditch. The inverted siphon structure is mainly composed of an inlet pipe, an outlet pipe and an inverted siphon connecting the two. It uses the gravity of the water flow to transport water through a specific pipe design. This structure can avoid construction difficulties caused by terrain height differences, reduce engineering costs and improve engineering efficiency.

[0003] The construction of inverted siphon includes foundation pit excavation, anchor pier and buttress construction. Anchor pier is a hydraulic structure set at the corner of the pipeline to prevent the pipeline from shifting. It is usually a reinforced concrete structure. The main function of the anchor pier is to fix the pressure pipeline and prevent it from shifting.

[0004] The concrete pouring of the anchor pier is completed in two pourings. The first pouring is to 30cm below the lowest stiffening ring at the bottom of the steel pipe, and the second pouring is to pour the remaining part after the steel pipe is installed and the steel bars are tied and welded. The pier is a structural support element, mainly used to support and stabilize the pipeline. The construction method of the pier is the same as the first construction method of the anchor pier, except that the pier has a support embedded part installed.

[0005] When installing the inverted siphon, it is usually installed from downstream to upstream. The pipe is fixed at the corner of the pipe with a pier. The pipe at this position cannot be adjusted. Therefore, in order to connect the downstream pipe, the pipe downstream of the pier has been installed on the pier when pouring the pier. In order to ensure the stability of the pier, the pier needs to be poured before the foundation pit is poured, that is, the foundation pit should be poured after the pipe is installed.

[0006] When pouring foundation pits, the concrete delivery device used is generally a pump truck. However, the outlet of the delivery pipe of the pump truck is a thick hose. When pouring, concrete is discharged from the hose. The hose is heavy and the workers cannot extend the hose under the inverted siphon, making it difficult for the concrete to be discharged under the inverted siphon. The workers can only handle it later, which is a lot of work. Summary of the invention

DETAILED DESCRIPTION

[0030] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0031] like Figure 1 As shown, during the inverted siphon construction, the foundation pit 200 is first excavated and processed, then the anchor pier 300 and the support pier 400 are poured and the inverted siphon pipe 500 is laid, and finally, the foundation pit 200 is poured. When pouring the foundation pit 200, since the inverted siphon pipe 500 is thick and the hose of the pump truck 100 is heavy when pumping concrete, the staff cannot extend the hose under the inverted siphon pipe 500, making it difficult to discharge the concrete under the inverted siphon pipe 500. The staff can only process it later. Based on this, the following technical solution is proposed.

[0032] Refer to the instruction manual Figure 1-Figure 9 A high-long-distance concrete conveying device for inverted siphon construction includes two groups of conveying units 1. The conveying unit 1 includes a self-propelled frame 2, which is used to move along the concrete pouring route. A mounting plate 21 is fixedly installed on the self-propelled frame 2, and a fixing frame 3 is fixedly installed on the mounting plate 21. A mudguard 4 is slidably installed on the fixing frame 3. The lower end of the mudguard 4 is located at the bottom of the fixing frame 3. A driving assembly 5 is installed on the fixing frame 3. The driving assembly 5 is used to drive the mudguard 4 to move along the length direction of the fixing frame 3. A nozzle 6 is fixedly installed at the bottom of the self-propelled frame 2, and the discharge port of the nozzle 6 faces the mudguard 4. When concrete is sprayed out from the discharge port of the nozzle 6, it hits the surface of the mudguard 4.

[0033] like Figure 1 As shown, in the above technical solution, the concrete conveying device also includes a pump truck 100, which is used to convey concrete to the nozzles 6 on the two conveying units 1 through the diversion pipe 9. An air inlet 61 is provided on one side of the nozzle 6, and the air inlet 61 is connected to the air flow injector.

[0034] It should be noted that when conveying concrete, the concrete is discharged from the discharge port of the nozzle 6 , and the airflow injector sprays compressed air, and the compressed air carries the concrete and sprays out quickly, hitting the surface of the fender 4 .

[0035] like Figure 5-Figure 9 As shown, in the above technical solution, the driving assembly 5 includes a power component 51, a driving rod 52 and a driving rod 53. The power component 51 is installed on one end of the fixed frame 3 close to the self-propelled frame 2, and one end of the driving rod 52 is installed on the output end of the power component 51, so that the power component 51 drives the driving rod 52 to swing, and one end of the driving rod 53 is installed on the upper end of the fender 4, and the ends of the driving rod 52 and the driving rod 53 close to each other are hinged.

[0036] Furthermore, the driving assembly 5 also includes a connecting member 54 and a connecting member 55, the connecting member 54 is fixedly installed on the output end of the power component 51, the end of the driving rod 52 is fixedly installed on the bottom end of the connecting member 54, the output shaft of the power component 51 is perpendicular to the axis of the driving rod 52, the connecting member 55 is rotatably installed on the upper end of the fender 4, one end of the driving rod 53 is fixedly installed on the upper end of the connecting member 55, and the axis of the driving rod 53 is perpendicular to the rotation axis of the connecting member 55.

[0037] It should be noted that the power component 51 is a reduction motor, and the output shaft of the power component 51 is arranged parallel to the rotation axis of the connecting member 55. The power component 51 drives the driving rod 52 to rotate through the connecting member 54, and the driving rod 52 drives the mudguard 4 to slide on the fixing frame 3 through the driving rod 53 and the connecting member 54, thereby changing the position of the mudguard 4 on the fixing frame 3.

[0038] In the above technical solution, a motor and running wheels are arranged on the self-propelled frame 2, and the running wheels are driven to move by the motor.

[0039] In this embodiment, the implementation method is as follows: during construction, Figure 1 As shown, the device is placed in an appropriate position and moved by the self-propelled frame 2. When pouring concrete, the fender 4 is first driven by the driving assembly 5 to move to the farthest position, which is the middle of the foundation pit 200. Then the pump truck 100 provides concrete to the nozzle 6, and the concrete is sprayed from the discharge port of the nozzle 6 to the fender 4, hitting the surface of the fender 4, and then the concrete will fall downward and then fall to the middle of the foundation pit 200. In the process of conveying concrete, the fender 4 is slowly driven by the driving assembly 5 to move toward the edge of the foundation pit 200, so that the concrete is gradually poured from the middle of the foundation pit 200 to the edge. When the fender 4 moves to the position closest to the edge of the foundation pit 200, the self-propelled frame 2 drives the conveying unit 1 to move forward a distance, and the driving assembly 5 drives the fender 4 to move to the middle position of the foundation pit 200, and the above pouring process is repeated.

[0040] The above technical solution transports concrete into the bottom of the inverted siphon 500 by concrete spraying. By setting the mudguard 4, the concrete spray is shot onto the surface of the mudguard 4 and then falls down to control the concrete pouring position. The mudguard 4 is driven to move back and forth by the driving component 5, thereby realizing the concrete pouring function from the middle to the edge of the foundation pit 200. Compared with the prior art, it is no longer necessary to manually hold a hose and extend it to the bottom of the inverted siphon 500 to achieve pouring.

[0041] Refer to the instruction manual Figure 1-Figure 9 The fixing frame 3 includes two side support frames 31 arranged side by side, one end of the two side support frames 31 are fixedly mounted on the mounting plate 21, and the sides of the two side support frames 31 close to each other are fixedly mounted on the inner support plate 32, the upper end of the fender 4 is arranged between the two inner support plates 32, and the two sides of the upper end of the fender 4 are respectively arranged to fit the side walls of the two inner support plates 32.

[0042] It should be noted that the two sides of the fender 4 are limited by the two inner support plates 32 , so that the fender 4 can move along the length direction of the inner support plates 32 .

[0043] During the concrete pouring process, due to the obstruction of the pier 400, the length of the fixed frame 3 cannot be extended to the middle of the foundation pit 200 to avoid collision with the pier 400. However, at this time, the fender 4 cannot be moved to the middle of the foundation pit 200. In order to prevent the concrete in the middle of the foundation pit 200 from being affected by the existence of the pier 400 during pouring, specifically, an extended-range component 7 is provided at one end of the fixed frame 3 away from the self-propelled frame 2. The extended-range component 7 includes a front plate 71, and guide rods 73 are fixedly installed at both ends of the front plate 71. Slide blocks 75 are fixedly installed at one end of the two guide rods 73 away from the front plate 71. The two slide blocks 75 are respectively slidably arranged inside the side support frame 31, and an elastic component 74 is sleeved on the outer side of the guide rod 73. The two ends of the elastic component 74 are respectively pressed against the slider 75 and the end of the side support frame 31.

[0044] Furthermore, two clamping plates 72 are provided at both ends of the front plate 71 close to the fender 4. The two clamping plates 72 are arranged opposite to each other up and down and one end of them is fixedly connected to 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 walls of the clamping plates 72 coincide with the side walls of the inner support plate 32.

[0045] In the above technical solution, the travel of the fender 4 is increased by setting the range-extending component 7. Figure 6 As shown, the range-extending component 7 is fitted with the end of the side support frame 31. When the pier 400 is not encountered, the mudguard 4 is driven to move forward by the driving component 5. When the mudguard 4 contacts the front plate 71 and continues to move, it will push the front plate 71 to extend 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 fixing frame 3. The two clamping plates 72 arranged up and down slide on the upper and lower surfaces of the inner support plate 32 respectively to improve the stability of the front plate 71 when moving. By extending the front plate 71, the moving stroke of the mudguard 4 is lengthened, so that the mudguard 4 can be moved to the middle of the foundation pit 200, and concrete is poured in the middle of the foundation pit 200. When encountering pier 400 during concrete pouring, it is only necessary to use the driving assembly 5 to drive the fender 4 forward to move the fender 4 to the end of the pier 400, and then pour concrete from this position toward the edge of the foundation pit 200. The position occupied by the pier 400 does not need to be poured.

[0046] Refer to the instruction manual Figure 1-Figure 7 and Fig. 9Two groups of conveying units 1 are set up, and 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. Its purpose is to connect the two conveying units 1 to improve stability, and to be able to avoid when encountering the pier 400. Specifically, the avoidance component 8 includes two arc tubes 81, and the two arc tubes 81 are respectively fixedly installed at one end of the fixed frames 3 of the two conveying units 1 that are close to each other. Power components 2 83 are installed on both fixed frames 3. The same arc connecting piece 82 is slidingly provided inside the two arc tubes 81. The two power components 2 83 are used to drive the arc connecting piece 82 to slide inside the arc tube 81.

[0047] Furthermore, gears 84 are fixedly mounted on the output ends of the two power components 83, a plurality of gear teeth 821 are provided on the outer side of the arc-shaped connecting member 82, and an opening is provided on the side wall of the arc-shaped tube 81, and the gears 84 mesh with the gear teeth 821 at the opening.

[0048] like Figure 2 As shown, under normal circumstances, the arc-shaped connecting member 82 is located inside the two arc-shaped tubes 81 at the same time, and the two arc-shaped tubes 81 are respectively fixed on the fixing frames 3 of the two conveying units 1, so that the two conveying units 1 are connected and supported by the arc-shaped connecting member 82. When pouring concrete, the opening of the arc-shaped connecting member 82 faces one side of the buttress 400. When encountering the buttress 400, and during the movement, when the buttress 400 is located in the middle of the arc-shaped connecting member 82, the power component 2 83 drives the arc-shaped connecting member 82 to move inside the two arc-shaped tubes 81 through the meshing of the gear 84 and the gear 821. After one end of the arc-shaped connecting member 82 enters the interior of one of the arc-shaped tubes 81, the other end of the arc-shaped connecting member 82 moves out from the other end of the arc-shaped tube 81, as shown in FIG. Figure 2 As shown, the arc-shaped connecting member 82 is rotated to the front of the pier 400. After the concrete at the position of the pier 400 is poured, the arc-shaped connecting member 82 is driven to rotate back by the second power component 83, that is, the opening of the arc-shaped connecting member 82 is directed toward the next pier 400. The second power component 83 is a motor.

[0049] Refer to the instruction manual Figure 1-Figure 2 The conveying unit 1 further includes a track 20 , which is arranged in the length direction of the slope 201 . The track 20 is used to carry the self-propelled frame 2 so that the self-propelled frame 2 moves on the track 20 .

[0050] It should be noted that, when in use, the track 20 is installed on the slope 201 . By setting the track 20 , the stability of the movement 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 foundation pit 200 .

[0051] The concrete conveying device is suitable for pouring foundation pits during inverted siphon construction, and is particularly suitable for pouring concrete on steep slopes of long-distance foundation pits where it is inconvenient for workers to stand during construction.

[0052] Finally: 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 in the protection scope of the present invention.
