Description

Technical Field

[0001] The present invention relates to the technical field of construction engineering, and particularly relates to a concrete pouring device for the side wall of a cable trench. Background Art

[0002] ‌In the field of building construction, as the degree of urban building intelligence is getting higher and higher, more and more cables need to be laid. For the convenience of maintenance, most cables are concentrated in the cable trench for wiring. Since the cable trench is located below the ground, it will be invaded by groundwater. Therefore, the waterproof requirement for the cable trench is relatively high, and concrete pouring is required. Generally, the side walls of the cable trench are all in the form of thin-walled structures, and it is difficult to pour concrete, resulting in low efficiency.

[0003] In the prior art, the patent with the application number CN202510369595.6 discloses a concrete rapid pouring device and construction method for a thin-walled side wall, which can pour the side wall of the cable trench. Its disadvantages are as follows: the lower part of its hopper is always in an open state and cannot control the opening and closing by itself, which is easy to cause accumulation; and during the pouring process, as the concrete liquid level below gradually rises, it is impossible to adjust the height of the hopper. Summary of the Invention

[0004] Aiming at the defects in the prior art, the present invention provides a concrete pouring device for the side wall of a cable trench to solve the problems that the pouring device in the prior art cannot control the opening and closing of the hopper by itself and adjust the height of the hopper.

[0005] A concrete pouring device for the side wall of a cable trench provided by the present invention includes a mobile vehicle frame, and a first lifting part is arranged on the mobile vehicle frame, and: A hopper, which is installed at the moving end of the first lifting part. A plurality of slurry outlet holes are opened on the bottom surface of the hopper, and a second lifting part is arranged at the top of the hopper; A grouting pipe, which corresponds to the slurry outlet holes one by one and is slidably located in the slurry outlet holes. The top end of the grouting pipe is connected to the moving end of the second lifting part through a pull rope.

[0006] It can be seen from the above technical solutions that in the present invention, the second lifting part pulls the grouting pipe to rise through the pull rope. When the pull rope is relaxed, the grouting pipe descends under the action of gravity. The grouting pipe can release the concrete at different depths in the hopper through lifting. When the top end of the grouting pipe is higher than the concrete liquid level, the grouting stops; During the grouting process, the first lifting part drives the hopper to lift and lower, which can change the position of the bottom end of the hopper to adapt to different pouring heights, and has a wider range of use.

[0007] Further, the first lifting part includes a first driving part, a plurality of guide columns and guide ears; A plurality of the guide posts are vertically arranged on the top of the movable vehicle frame. Guide ears corresponding to the guide posts one by one are fixedly arranged on the side wall of the hopper. The guide ears are slidably sleeved on the outer peripheral wall of the guide posts. The first driving part is arranged on the top of the movable vehicle frame. The first driving part is in power connection with the hopper and is used to drive the hopper to lift and lower.

[0008] The beneficial effect is that the guide posts guide the movable vehicle frame, making the lifting and lowering of the movable vehicle frame smooth and without deviation.

[0009] Further, the first driving part includes two support columns respectively fixed on both sides of the movable vehicle frame. Rotating arms are hinged on the support columns. Traction grooves are respectively arranged at one ends of the two rotating arms close to the hopper. Traction rods are fixedly arranged on the side walls of the hopper facing the traction grooves. The traction rods are slidably located in the traction grooves. One ends of the two rotating arms far from the hopper are fixedly connected through a connecting column; A telescopic element is also hinged on the movable vehicle frame. A sleeve is fixedly arranged at the moving end of the telescopic element. The sleeve is sleeved on the connecting column.

[0010] The beneficial effect is that rotating arms are arranged on both sides of the hopper, and the force-bearing structure is balanced, which is better for pushing the hopper to lift and lower. The telescopic element drives the rotating arm based on the lever principle, which can significantly reduce the power required to push the hopper, thereby reducing power consumption.

[0011] Further, the second lifting part includes a portal frame, a sliding plate, a sliding groove and a second driving part; The portal frame is fixedly arranged on the top of the hopper. Sliding grooves are respectively arranged on the inner walls of the two opposite sides of the portal frame. The length direction of the sliding grooves points to the slurry outlet hole. Both ends of the sliding plate are slidably located in the sliding grooves. One end of the pull rope is arranged on the sliding plate, and the other end is fixed on the grouting pipe; The second driving part is arranged on the portal frame. The second driving part is in power connection with the sliding plate and is used to drive the sliding plate to slide.

[0012] The beneficial effect is that the sliding grooves guide the sliding plate, making the sliding direction of the sliding plate face the slurry outlet hole to avoid deviation.

[0013] Further, the second driving part includes a motor and a threaded rod; The threaded rod is rotatably installed on the portal frame. The axis of the threaded rod is parallel to the sliding groove. The sliding plate is sleeved on the threaded rod and is in threaded connection with the threaded rod. A motor is fixedly arranged on the portal frame. The output shaft of the motor is fixedly connected with the threaded rod.

[0014] The beneficial effect is that the thread angle of the threaded rod has a self-locking effect. When the motor does not work, the sliding plate will not slide up and down by itself due to the shaking of the movable vehicle frame.

[0015] Further, a plurality of push columns are detachably connected to one end of the skateboard facing the grouting pipe. The push columns correspond to the slurry outlet holes one by one. One end of the pull rope is fixedly connected to the push column, and the other end is fixedly connected to the grouting pipe.

[0016] The beneficial effects are as follows: The push column moves with the skateboard. If the grouting pipe gets stuck when sliding down, the push column can push it to continue descending; the push column can be detachably replaced with different lengths to change the limit stroke of the descent of the grouting pipe.

[0017] Further, a scraper is fixedly installed on the bottom surface of the mobile vehicle frame through a permanent magnet. The scraper is located below the slurry outlet hole. Scraper holes corresponding to the slurry outlet holes one by one are formed on the scraper. The scraper holes are larger than the slurry outlet holes. The lower end of the grouting pipe passes through the scraper holes.

[0018] The beneficial effects are as follows: By removing the scraper and holding it to move up and down, the outer peripheral wall of the grouting pipe can be cleaned. The structure is simple and easy to use. BRIEF DESCRIPTION OF THE DRAWINGS

DETAILED DESCRIPTION OF THE EMBODIMENTS

[0022] The embodiments of the technical solution of the present invention will be described in detail below with reference to the accompanying drawings. The following embodiments are only used to more clearly illustrate the technical solution of the present invention, so they are only examples and cannot be used to limit the protection scope of the present invention.

[0023] Embodiment 1 As Figures 1 to 4 shown, a concrete pouring device for the side wall of a cable trench includes a moving vehicle frame 1, a first lifting part 2 is arranged on the moving vehicle frame 1, and: A hopper 3 is installed at the moving end of the first lifting part 2. A plurality of slurry outlet holes 4 are opened on the bottom surface of the hopper 3, and a second lifting part 5 is arranged at the top of the hopper 3; A grouting pipe 6, the grouting pipe 6 corresponds to the slurry outlet hole 4 one by one and is slidably located in the slurry outlet hole 4. The top end of the grouting pipe 6 is connected to the moving end of the second lifting part 5 through a pulling rope 7.

[0024] In this embodiment, when the formwork is erected on the side wall of the cable trench and concrete needs to be poured, the moving vehicle frame 1 is driven above the cable trench. In the initial state, the bottom end of the grouting pipe 6 extends out of the slurry outlet hole 4 and is aligned with the cable trench. The second lifting part 5 is at a high position. The top end of the grouting pipe 6 is pulled by the pulling rope 7 to be higher than the liquid level of the concrete slurry in the hopper 3, and the concrete slurry in the hopper 3 will not flow out; When the second lifting part 5 descends a certain distance and the pulling rope 7 is relaxed, the grouting pipe 6 descends under the action of gravity until the pulling rope 7 is straightened again. During this process, if the top end of the grouting pipe 6 is lower than the concrete liquid level in the hopper 3, the concrete slurry will flow into the grouting pipe 6 from the top end, flow out from the bottom end of the grouting pipe 6, and finally flow into the cable trench for concrete pouring; Due to reasons such as precipitation, the concrete slurry at different depths in the hopper 3 has slight differences. By adjusting the top end of the grouting pipe 6 to stay at different depths in the hopper 3 through the second lifting part 5, the concrete at different depths in the hopper 3 can be released, and the selection is more diverse.

[0025] Specifically, the falling height of the concrete during pouring should not exceed two meters. If the drop is too large, the concrete will segregate, affecting the strength of the finished product. Therefore, the bottom end of the grouting pipe 6 needs to extend into the cable trench; When a certain amount of concrete is poured, the concrete in the cable trench gradually fills up and will submerge the bottom end of the grouting pipe 6, resulting in the slurry being unable to flow out normally. Therefore, the bottom end of the grouting pipe 6 needs to continuously rise and always be above the concrete liquid level in the cable trench; During the pouring process, as the liquid level in the hopper 3 drops, the first lifting part 2 is activated to drive the hopper 3 to rise. At the same time, the second lifting part 5 descends, the pulling rope 7 is relaxed, and the grouting pipe 6 descends under the action of gravity. The descending speed of the grouting pipe 6 is less than the rising speed of the hopper 3, and the top end of the grouting pipe 6 is always below the liquid level of the hopper 3, achieving the effect that the bottom end of the grouting pipe 6 rises relative to the cable trench while the concrete pouring is not interrupted.

[0026] In addition, in this solution, there are multiple grouting pipes 6, which are arranged in sequence along the advancing direction of the moving vehicle frame 1. The moving vehicle frame 1 moves forward a distance equal to its own length each time it pours. However, the length of the cable trench is usually not an integer multiple of the length of the moving vehicle frame 1 itself. Therefore, when the moving vehicle frame 1 moves to one end of the cable trench, the remaining area to be poured is usually less than the length of the moving vehicle frame 1 itself, and some of the grouting pipes 6 are located outside the cable trench; At this time, the second lifting part 5 descends, the pulling rope 7 is relaxed, and the grouting pipe 6 located outside the cable trench is blocked by the ground and cannot descend, achieving the effect of automatically closing the grouting pipe 6. Since the pulling rope 7 is a flexible structure, it will not block the descent of the second lifting part 5. Therefore, the grouting pipe 6 located inside the cable trench can still normally descend under the action of gravity to connect the concrete slurry in the hopper 3 for pouring.

[0027] Embodiment 2 As Figures 2 to 4 shown, preferably, on the basis of Embodiment 1, the first lifting part 2 includes a first driving part, a plurality of guide columns 201 and guide ears 202; A plurality of the guide columns 201 are vertically arranged on the top of the moving vehicle frame 1. Guide ears 202 corresponding to the guide columns 201 one by one are fixedly arranged on the side wall of the hopper 3. The guide ears 202 are slidably sleeved on the outer peripheral wall of the guide columns 201. The first driving part is arranged on the top of the moving vehicle frame 1, and the first driving part is power-connected to the hopper 3 to drive the hopper 3 to lift and lower.

[0028] As Figures 2 to 4 shown, the first driving part includes two support columns 203 respectively fixed on both sides of the moving vehicle frame 1. Rotating arms 204 are hinged on the support columns 203. Traction grooves 205 are formed at one ends of the two rotating arms 204 close to the hopper 3. Traction rods 206 are fixedly arranged on the side walls of the hopper 3 facing the traction grooves 205. The traction rods 206 are slidably located in the traction grooves 205. One ends of the two rotating arms 204 far from the hopper 3 are fixedly connected by a connecting column 207; A telescopic element 208 is also hingedly arranged on the moving vehicle frame 1. A sleeve 209 is fixedly arranged at the moving end of the telescopic element 208. The sleeve 209 is sleeved on the connecting column 207.

[0029] AsFigures 2 to 4 As shown, the second lifting part 5 includes a gantry 501, a sliding plate 502, a sliding groove 503 and a second driving part; The gantry 501 is fixedly arranged on the top of the hopper 3. Sliding grooves 503 are formed on the inner walls of the opposite sides of the gantry 501. The length direction of the sliding groove 503 points to the slurry outlet hole 4. Both ends of the sliding plate 502 are slidably located in the sliding groove 503. One end of the pulling rope 7 is arranged on the sliding plate 502, and the other end is fixed to the grouting pipe 6; The second driving part is arranged on the gantry 501. The second driving part is power-connected to the sliding plate 502 for driving the sliding plate 502 to slide; As Figures 2 to 4 shown, the second driving part includes a motor 504 and a threaded rod 505; The threaded rod 505 is rotatably installed on the gantry 501. The axis of the threaded rod 505 is parallel to the sliding groove 503. The sliding plate 502 is sleeved on the threaded rod 505 and is threadedly connected to the threaded rod 505. A motor 504 is fixedly arranged on the gantry 501, and the output shaft of the motor 504 is fixedly connected to the threaded rod 505.

[0030] In this embodiment, when the telescopic element 208 expands and contracts, it drives the sleeve 209 to move up and down. The connecting column 207 rotates inside the sleeve 209. The sleeve 209 drives the connecting column 207 to move up and down. One end of the connecting column 207 drives the rotating arm 204 to swing, and the other end of the rotating arm 204 drives the traction rod 206 to move up and down. The traction rod 206 drives the hopper 3 to move up and down along the guide post 201; The telescopic element 208 drives the rotating arm 204 to swing based on the lever principle, which can significantly reduce the power required to push the fully loaded hopper 3, thereby reducing power consumption.

[0031] Specifically, the motor 504 drives the threaded rod 505 to rotate, and the threaded rod 505 drives the sliding plate 502 to rotate. Since both ends of the sliding plate 502 are restricted by the sliding groove 503, the rotational motion is converted into a linear motion, and the sliding plate 502 slides up and down along the sliding groove 503, driving the pulling rope 7 to be straightened or relaxed; The thread angle of the threaded rod 505 has a self-locking effect. When the motor 504 is not working, the sliding plate 502 will not slide up and down by itself due to the shaking of the moving vehicle frame 1.

[0032] On the basis of this embodiment, the telescopic element 208 can be any device with a telescopic function such as a hydraulic cylinder, a pneumatic cylinder or an electric telescopic rod.

[0033] Embodiment 3 As Figures 1 to 3As shown, preferably, on the basis of Embodiments 1-2, one end of the sliding plate 502 facing the grouting pipe 6 is detachably connected with a plurality of pushing columns 506. The pushing columns 506 correspond to the slurry outlet holes 4 one by one. One end of the pulling rope 7 is fixedly connected with the pushing column 506, and the other end is fixedly connected with the grouting pipe 6.

[0034] In this embodiment, in the initial state, the bottom end of the grouting pipe 6 extends out of the slurry outlet hole 4 and aligns with the cable trench. After the sliding plate 502 descends to a certain extent, the pulling rope 7 is relaxed, and the grouting pipe 6 descends under the action of gravity. If the descent of the grouting pipe 6 gets stuck, the sliding plate 502 is started to descend a certain distance again. The pushing column 506 contacts the top surface of the grouting pipe 6 to push the grouting pipe 6 to continue descending. After reaching the predetermined position, the sliding plate 502 ascends again to tighten the pulling rope 7.

[0035] On the basis of this embodiment, the detachable connection between the pushing column 506 and the sliding plate 502 is a threaded connection or a snap connection, which is convenient for disassembly and replacement. If the length of the pulling rope 7 remains unchanged, by replacing the pushing columns 506 with different lengths, the limit stroke of the descent of the grouting pipe 6 can be changed.

[0036] Embodiment 4 As Figure 5 shown, preferably, on the basis of Embodiments 1-3, the bottom surface of the moving vehicle frame 1 is fixedly installed with a scraping plate 9 through a permanent magnet 8. The scraping plate 9 is located below the slurry outlet hole 4. The scraping plate 9 is provided with scraping plate holes 10 corresponding to the slurry outlet holes 4 one by one. The scraping plate holes 10 are larger than the slurry outlet holes 4, and the lower end of the grouting pipe 6 passes through the scraping plate holes 10.

[0037] In this embodiment, in the pouring working state, the scraping plate 9 is fixedly adsorbed on the bottom surface of the moving vehicle frame 1. The scraping plate holes 10 correspond to the slurry outlet holes 4, and the scraping plate holes 10 are slightly larger than the slurry outlet holes 4. The grouting pipe 6 can easily pass through the scraping plate holes 10. After the pouring is completed, the moving vehicle frame 1 is hoisted. The sliding plate 502 descends to the lowest position, and the grouting pipe 6 descends to the lowest position. The top end of the grouting pipe 6 is flush with the inner bottom surface of the hopper 3. Then, the hopper 3 is rinsed, and the waste liquid flows out through the grouting pipe 6. The staff removes the scraping plate 9 and holds it to move up and down. The inner wall of the scraping plate hole 10 collides and scrapes with the outer wall of the grouting pipe 6 to clean the concrete on the outer wall of the grouting pipe 6, completing the cleaning work.

[0038] The above embodiments are only used to illustrate the technical solutions of the present invention, rather than to limit it; although the present invention has been described in detail with reference to the foregoing embodiments, those of ordinary skill in the art should understand that: they can still modify the technical solutions recorded in the foregoing embodiments, or perform equivalent replacements on some or all of the technical features; and these modifications or replacements do not cause the essence of the corresponding technical solutions to deviate from the scope of the technical solutions of the various embodiments of the present invention, and they should all be covered within the scope of the claims and the specification of the present invention.
