Description

Technical Field

[0001] This application relates to the field of railway track construction technology, and in particular to a hopper for pouring concrete for subway track columns. Background Technology

[0002] During the construction of column-type inspection pits in subway depots, to ensure accurate track positioning and elevation, the tracks must be installed first, followed by the pouring of the supporting columns at the bottom of the tracks, with the top already fitted with rail anchor plates. Due to the small size of the columns, construction workers typically use shovels and other tools to pour concrete into the columns and then vibrate it to ensure compaction. However, during concrete pouring, the vibrator easily splashes concrete onto the rails, causing contamination and making cleaning difficult. Summary of the Invention

[0003] To reduce the possibility of the track being contaminated by concrete during the concrete pouring process, this application provides a concrete pouring hopper for subway track columns.

[0004] This application provides a casting hopper for subway track columns, which adopts the following technical solution:

[0005] A concrete pouring hopper for subway track columns includes a hopper for holding concrete, guide wheels for moving on the track are installed at the bottom of the hopper, a pouring assembly for pouring concrete into the column is provided on the hopper, and a vibrating assembly for vibrating the concrete is provided on the hopper. The vibrating assembly includes a vibrating rod that slides vertically in the hopper and a drive source for driving the vibrating rod. The vibrating rod is installed on the outer wall of the hopper, and a separator is provided on the vibrating rod. The separator can move into the column and isolate the concrete from the track.

[0006] By adopting the above technical solution, when the hopper moves from the track to above the column, and the pouring component and the vibrating component are aligned with different column positions, pouring and vibrating work can be carried out on different columns simultaneously, thereby improving the construction efficiency of column concrete; and when the vibrating rod is inserted into the column formwork to vibrate the concrete, the separator covers the concrete, reducing the probability of concrete splashing onto the track caused by the vibrating rod during vibration, thereby reducing the possibility of the rail being contaminated by concrete.

[0007] Preferably, the bottom wall of the hopper is provided with a discharge port, and the casting assembly includes a retractable folding tube that communicates with the discharge port. The end of the folding tube away from the hopper is connected to a casting pipe, which can extend into the column.

[0008] By adopting the above technical solution, the folded pipe can increase the range of concrete pouring in the hopper. By stretching the folded pipe, the pouring pipe can be lowered to the bottom of the column, thereby reducing the probability of concrete splashing onto the rails when the pouring pipe is too close to the rails, thus reducing the probability of rail contamination.

[0009] Preferably, the casting assembly further includes an on / off valve disposed at the discharge port, the on / off valve including a passage communicating with the discharge port and a baffle plate movably disposed within the on / off valve for opening and closing the passage.

[0010] By adopting the above technical solution, the barrier plate can block the passage, thereby controlling the start and stop of concrete pouring.

[0011] Preferably, a valve stem is rotatably connected inside the valve, the baffle plate is fixedly connected to the valve stem, one end of the valve stem is provided with a gear, the gear meshes with a rack, and one end of the rack protrudes through the outer wall of the valve.

[0012] By adopting the above technical solution, pulling the rack causes the valve stem to rotate, which in turn drives the baffle plate to rotate within the passage, thereby adjusting the size of the passage and controlling the pouring speed of concrete within the passage. This facilitates the pouring of columns by construction personnel and reduces the problems of concrete waste caused by excessively fast unloading speed and construction efficiency affected by excessively slow unloading speed.

[0013] Preferably, a limiting rod is provided on the opening and closing valve. The limiting rod slides inside the opening and closing valve and moves in a direction perpendicular to the movement direction of the rack. The limiting rod is used to be inserted into the adjacent teeth of the rack.

[0014] By adopting the above technical solution, the limiting rod is inserted into the adjacent teeth of the rack, thereby limiting the valve stem and reducing the possibility of the baffle plate rotating in the passage due to the impact of concrete on the baffle plate.

[0015] Preferably, the outer wall of the hopper is equipped with a receiving chamber, and the vibrating rod is located inside the receiving chamber and can move vertically within the receiving chamber.

[0016] By adopting the above technical solution, the receiving chamber plays a role in containing and protecting the vibrating rod. When the vibrating rod needs to be used, it is moved down into the column for vibration work. After the vibration is completed, the vibrating rod can be moved into the receiving chamber.

[0017] Preferably, the vibrating rod is connected to a traction rope at one end, and a drum is rotatably mounted on the top wall of the receiving chamber, with the end of the traction rope away from the vibrating rod passing through the top wall of the receiving chamber and wound around the drum.

[0018] By adopting the above technical solution, the drum can wind and unwind the traction rope, thereby lifting the vibrator and enabling it to move vertically. This eliminates the need for manual lifting and vibration of the vibrator, saving time and effort.

[0019] Preferably, the separator includes a geotextile wrapped around the outer wall of the vibrating rod, the geotextile being circular and the vibrating rod passing through the center of the geotextile, the geotextile partially wrapping the vibrating rod, and a locking ring fitted on the vibrating rod, the locking ring being movable and fixed on the vibrating rod.

[0020] By adopting the above technical solution, when the vibrator is lowered into the column, the geotextile acts as a barrier between the concrete and the track. When the vibrator is vibrating, the concrete splashed near the vibrator is blocked by the geotextile, reducing the possibility of concrete splashing onto the track. Furthermore, the locking ring can hold and lock the geotextile to the vibrator, facilitating the geotextile's entry through the column opening and reducing the possibility of residual concrete on the geotextile contaminating the track due to contact between the geotextile and the track.

[0021] Preferably, a cleaning cloth is fixed on the inner wall of the positioning ring.

[0022] By adopting the above technical solution, since one side of the geotextile is laid on the concrete surface, concrete slurry will remain on the side of the geotextile in contact with the concrete. During the process of the positioning ring moving on the vibrator and collecting the geotextile, the cleaning cloth will clean the geotextile, reducing the amount of residual concrete slurry on the geotextile. This reduces the possibility of concrete slurry from the geotextile dripping onto the track and contaminating it during the lifting of the vibrator.

[0023] In summary, this application includes at least one of the following beneficial technical effects:

[0024] 1. It can simultaneously perform pouring and vibration work on different columns, thereby improving the construction efficiency of column concrete; and when the vibrator is inserted into the column formwork to vibrate the concrete, the separator covers the concrete surface, reducing the probability of concrete splashing onto the track due to the vibrator's vibration work, thus reducing the possibility of the rail being contaminated by concrete.

[0025] 2. The folded pipe can increase the range of concrete pouring from the hopper. By stretching the folded pipe, the pouring pipe can be lowered to the bottom of the column, thereby reducing the probability of concrete splashing onto the rails when the pouring pipe is too close to the rails, thus reducing the probability of rail contamination.

[0026] 3. The rack and pinion cause the valve stem to rotate, which in turn drives the baffle plate to rotate within the passage, thereby adjusting the size of the passage and controlling the pouring speed of concrete within the passage. This facilitates the pouring of the column by construction personnel and reduces the problems of concrete waste caused by excessively fast unloading speed and the impact on construction efficiency caused by excessively slow unloading speed.

[0027] 4. The geotextile will block concrete splashes near the vibrator, reducing the possibility of concrete splashing onto the track. Furthermore, the locking ring can hold and lock the geotextile to the vibrator, facilitating the geotextile's entry through the column opening and reducing the possibility of residual concrete on the geotextile contaminating the track due to contact with the track.

[0028] 5. As the positioning ring moves along the vibrator and collects the geotextile, the cleaning cloth cleans the geotextile, reducing the amount of residual concrete slurry on it. This reduces the possibility of concrete slurry dripping from the geotextile onto the track and contaminating it during the lifting process of the vibrator. Attached Figure Description

[0036] The following is in conjunction with the appendix Figure 1-6 This application will be described in further detail.

[0037] This application discloses a casting hopper for subway track columns, referring to... Figure 1 The system includes a rectangular hopper 1. Several fixed seats are mounted on both sides of the bottom wall of the hopper 1. Guide wheels 11, which move on a track 8, are rotatably connected within the fixed seats. Brakes 12 are mounted on the fixed seats to press against the guide wheels 11 and limit their rotation. When the hopper 1 moves on the track 8 above the column 7, pressing the brakes 12 brakes the hopper 1, allowing it to remain stationary above the column 7, thus completing the pouring and vibration of the column 7. This reduces the likelihood of the hopper 1 slipping and affecting the pouring and vibration of the column 7.

[0038] Reference Figure 2 and Figure 3 The hopper 1 includes two sub-hoppers 13, each with an inverted pyramidal bottom. Each sub-hopper 13 has a discharge port 14 at its bottom. When the hopper moves, the two discharge ports 14 can be aligned with the columns 7 at the bottom of the two side rails 8. The two inverted pyramidal sub-hoppers 13 can completely discharge the concrete in the hopper 1, reducing the possibility that some concrete will solidify in the hopper due to difficulty in discharge.

[0039] Reference Figure 3 and Figure 4 The hopper 1 is equipped with a casting component 2. The casting component 2 includes an opening and closing valve 21 installed at the discharge port 14. The opening and closing valve 21 includes a valve body 211. A passage 218 communicating with the discharge port 14 is vertically provided inside the valve body 211. Two opposing cavities 212 are opened in the inner wall of the passage 218. A rubber pad 219 is fixedly connected in the cavity 212. The rubber pad 219 fills the cavity 212 and seals the cavity 212.

[0040] A valve stem 213 is installed inside the valve body 211, passing through the cavity 212 and inserted into the rubber pad 219, and is rotatably connected to the rubber pad 219. A baffle plate 214 is fixedly connected to the valve stem 213 located in the passage 218. The baffle plate 214 is circular and its diameter is equal to that of the passage 218. When the baffle plate 214 rotates to a certain angle in the passage, it can close the passage 218, thereby controlling the discharge from the discharge port 14. When the baffle plate 214 rotates to different angles with the bottom wall of the hopper 1, it can adjust the flow rate of the discharge from the discharge port 14, thereby facilitating the pouring of concrete by construction personnel and reducing the problems of concrete waste caused by excessively fast discharge speed and the impact on construction efficiency caused by excessively slow discharge speed.

[0041] Reference Figure 4A gear 215 is fixedly connected to the valve stem 213. The gear 215 is coaxially arranged with the valve stem 213, and a rack 216 meshes with the gear 215. One end of the rack 216 extends out of the valve body 211 and is connected to a handle. A limit hole is provided on the valve body 211, and threads are provided on the side wall of the limit hole. A limit rod 217 passes through the limit hole and is threaded to the side wall of the limit hole. One end of the limit rod 217 located inside the valve body 211 can be inserted into the adjacent tooth of the rack 216. When it is necessary to rotate the valve stem 213, rotating the limit rod 217 separates the limit rod 217 from the rack 216. Pulling the handle causes the rack 216 to move vertically, thereby driving the valve stem 213 to rotate. When the baffle plate 214 rotates to the predetermined angle, the rotating limit rod 217 causes the end of the limit rod 217 to abut against and be fixed with the rack 216, thereby limiting the valve stem 213 and reducing the occurrence of the baffle plate 214 rotating in the passage 218 due to the impact of concrete on the baffle plate 214.

[0042] Reference Figure 1 The opening and closing valve 21 has a folded pipe 22 fixed at the end away from the discharge port 14, which is connected to the passage 218. The folded pipe 22 is a corrugated pipe and can be extended and retracted. The end of the folded pipe 22 away from the opening and closing valve 21 is connected to the pouring pipe 23. The pouring pipe 23 is made of steel, which is convenient for construction personnel to operate and construct. When it is necessary to pour the column 7, the folded pipe 22 is stretched so that the pouring pipe 23 can be inserted into the column 7 template. After the column 7 is poured, the folded pipe 22 is folded back.

[0043] Reference Figure 1 and Figure 5 A receiving chamber 3 is installed on one outer wall of the hopper 1. The receiving chamber 3 is a rectangular box shape, and two partitions 31 are provided inside the receiving chamber 3, dividing the receiving chamber 3 into three receiving spaces. The receiving spaces on both sides are cylindrical with through bottom walls, and the receiving space in the middle is rectangular. The hopper 1 is equipped with a vibrating assembly 4, which includes a vibrating rod 41 capable of automatic vibration and a drive source 42 for driving the vibrating rod 41. The drive source 42 is a power supply and is placed in the receiving space in the middle position. There are two vibrating rods 41, which are placed in the receiving spaces on both sides respectively. Two connecting wires 43 are fixed on the drive source 42. The two connecting wires 43 pass through the two partitions 31 respectively and are electrically connected to the vibrating rods 41 on both sides. The specific structure of the vibrating rods 41 is an existing structure and will not be described in detail here.

[0044] Reference Figure 1 and Figure 5The vibrating rod 41 is connected to a traction rope 5 at its end. Two drums 51 are fixedly connected to the top plate of the receiving chamber 3. The two drums 51 are respectively set above the receiving spaces on both sides. A drive motor 53 is set between the axes of the two drums 51. A transmission rod 52 is connected to the end of each of the two drums 51, and the end of the transmission rod 52 away from the drum 51 is connected to the output end of the drive motor 53.

[0045] When the drive motor 53 starts, it drives the transmission rod 52 to rotate. By rotating the drive motor 53 in different directions, it drives the drum 51 to rotate, thereby winding and unwinding the traction rope 5, which allows the vibrator 41 to move vertically. After the concrete in the column 7 is poured, the hopper 1 moves so that the vibrating assembly 4 is above the poured column 7. The drive motor 53 rotates, causing the drum 51 to unwind the traction rope 5, so that the vibrator 41 is lowered vertically into the column 7 and vibrates the concrete in the column 7. After vibration, the drive motor 53 drives the drum 51 to wind up the traction rope 5, thereby lifting the vibrator 41 into the receiving chamber 3.

[0046] Reference Figure 5 and Figure 6 The vibrating rod 41 is equipped with a separator 6, which includes a circular geotextile 61. The vibrating rod 41 passes through the center of the geotextile 61 and is fixedly connected to the center of the geotextile 61. A locking ring 62 is fitted onto the vibrating rod 41. The locking ring 62 is a clamp, and a cleaning cloth 63 is fixedly connected to the inner wall of the clamp. The locking ring 62 is fitted over the geotextile 61 and can move along the vibrating rod 41, and is fixed by bolts. When the locking ring 62 moves onto the geotextile 61, it can roll up the geotextile 61, so that the geotextile 61 partially wraps the vibrating rod 41. After the locking ring 62 moves, it locks its position by rotating the bolts on it.

[0047] When the vibrator 41 is inserted into the formwork of column 7, the locking ring 62 is moved downwards to allow the geotextile 61 to spread out until it floats entirely on the concrete surface, at which point the locking ring 62 is fixed to the vibrator 41. During operation, the geotextile 61 isolates the concrete from the rails, reducing the possibility of concrete slurry splashing onto the rails during vibration, thus minimizing rail contamination. After vibration is complete, the locking ring 62 is moved upwards, allowing the geotextile 61 to rise until it completely encloses the vibrator 41. As the locking ring 62 moves, the cleaning cloth 63 performs preliminary cleaning of the concrete on the geotextile 61, reducing the amount of slurry adhering to it.

[0048] The implementation principle of this application embodiment is as follows: When the hopper 1 is filled with concrete, the hopper 1 moves on the track 8. When the hopper 1 moves above the column 7 on the track 8, the brake 12 is pressed to brake the hopper 1, so that the two pouring pipes 23 are respectively aligned with the columns 7 on both sides of the track 8. The folding pipe 22 is stretched so that the pouring pipe 23 is placed into the template of the column 7, and the limiting rod 217 is rotated to separate the limiting rod 217 from the rack 216. The handle is held and the rack 216 is pulled to drive the valve stem 213 to rotate. When the baffle plate 214 rotates to a predetermined angle, the limiting rod 217 is rotated so that the limiting rod 217 presses against the rack 216, so that the hopper 13 can pour concrete onto the column 7. After the pouring of the column 7 is completed, the baffle plate 214 closes the passage 218 and the folding pipe 22 is retracted and folded.

[0049] The hopper 1 is moved again so that the pouring pipe 23 aligns with the next set of columns 7. At the same time, the vibrating assembly 4 is moved to a position directly above the completed column 7. The above operation is repeated to complete the concrete pouring of the column 7. Simultaneously, the drive motor 53 rotates, causing the drum 51 to unwind the traction rope 5, allowing the vibrating rod 41 to be vertically lowered into the completed column 7. The bolts are loosened, and the locking ring 62 is moved to spread the geotextile 61 until it is evenly spread on the concrete surface. The locking ring 62 is then fixed to the vibrating rod 41, and the drive source 42 is turned on so that the vibrating rod 41 vibrates the concrete inside the column 7. The geotextile 61 can isolate the concrete from the rail, reducing the possibility of concrete slurry splashing onto the rail during the vibration process, thereby reducing the possibility of the rail being contaminated by concrete.

[0050] After vibration is completed, the drum 51 is driven to rotate, thereby winding up the traction rope 5 and lifting the vibrator 41 from the column 7 into the receiving chamber 3. Simultaneously, the locking ring 62 moves upward, causing the geotextile 61 to rise until it partially wraps around the vibrator 41 and is locked with bolts. During the movement of the locking ring 62, the cleaning cloth 63 can initially clean the concrete on the geotextile 61, reducing the amount of mud adhering to it. Then, the drive motor 53 drives the drum 51 to wind up the traction rope 5, thereby pulling the vibrator 41 into the receiving chamber 3.

[0051] The distance between the pouring component 2 and the vibrating component 4 is equal to the distance between two adjacent columns 7 on the same side, so that concrete can be poured and vibrated at the same time, thereby improving construction efficiency.

[0052] The above are all preferred embodiments of this application, and are not intended to limit the scope of protection of this application. Therefore, all equivalent changes made in accordance with the structure, shape and principle of this application should be covered within the scope of protection of this application.
