Description

Technical Field

[0001] This application relates to the field of concrete pouring technology, and in particular to a hopper for hoisting and pouring concrete. Background Technology

[0002] During the construction of super high-rise buildings, cranes are typically used to lift hoppers filled with concrete to the construction height of the walls and columns, and then the discharge port at the bottom of the hopper is opened for concrete pouring.

[0003] In related technologies, such as Chinese patent document CN111706081A, a concrete crane hopper is disclosed. The hopper includes a lower truncated cone and an upper cylindrical body. The hopper support is composed of a frame base and columns erected around the base. A pair of semi-circular steel plates are spliced ​​together to form a circular sealing plate that closes the discharge port. On the outer circumference of the concrete hopper, a pair of mutually meshing and rotating sector teeth are respectively arranged on symmetrical sides. The symmetrical sides of the semi-circular steel plates are respectively welded with upwardly protruding longitudinal connecting rods. The top of the longitudinal connecting rods is fixedly connected to the sector teeth at the corresponding positions. One side of the semi-circular steel plate is the driving plate, and the other side is the driven plate. A connecting block is fixedly welded to the outer side of the driving plate. A steel pipe wrench is hinged to the bottom end of the frame base on the side where the connecting block is located. One end of the connecting rod is hinged to the steel pipe wrench, and the other end is hinged to the connecting block. When discharging material, release the steel pipe wrench from the buckle and pull it downwards. This will pull the longitudinal connecting rod through the connecting rod, and the meshing rotating sector tooth will cause the driven plate to separate from the driving plate, thus opening the hopper outlet.

[0004] Regarding the aforementioned technologies, during material discharge, concrete continuously flows out of the discharge port from the hopper. When it is necessary to urgently close the discharge port, due to the large quantity and weight of the concrete, the operator needs to exert considerable force to turn the steel pipe wrench upwards, making it difficult to close the discharge port in a timely manner. Summary of the Invention

[0005] To facilitate the timely closure of the hopper's outlet in case of emergencies, this application provides a hopper for hoisting and pouring concrete.

[0006] The technical solution for a concrete pouring hopper provided in this application is as follows:

[0007] A hopper for hoisting concrete pouring includes a hopper body and a steel pipe wrench hinged to the hopper body. A first drum is rotatably mounted on the side of the hopper body near the steel pipe wrench. A first connecting rope is wound on the first drum. The end of the first connecting rope away from the first drum is connected to the end of the steel pipe wrench away from the discharge port of the hopper body. The hopper body is provided with an operation button and a braking assembly for driving the first drum to rotate and winding the first connecting rope. The operation button is electrically connected to the braking assembly.

[0008] Preferably, the braking assembly includes a gear coaxially connected to the first drum, a rack slidably disposed on the hopper body, and a driving member disposed on the hopper body. The sliding direction of the rack is perpendicular to the rotation axis of the first drum. The rack is used to mesh with the gear. The driving member is electrically connected to an operation button. The driving member is used to drive the rack to slide and drive the gear to rotate.

[0009] Preferably, the driving component includes a cylinder mounted on the hopper body, the rack is connected to the piston rod of the cylinder, and the cylinder is electrically connected to an operation button.

[0010] Preferably, a contact switch is provided on the side of the hopper body near the steel pipe wrench. The contact switch is electrically connected to the cylinder. When the steel pipe wrench abuts against the contact switch, the discharge port of the hopper body is closed, and the contact switch drives the cylinder to stop working.

[0011] Preferably, a scraper ring is slidably disposed within the hopper body, the sliding direction of the scraper ring is parallel to the depth direction of the hopper body, the outer wall of the scraper ring abuts against the inner wall of the hopper body, and the hopper body is provided with an adjustment mechanism for adjusting the sliding of the scraper ring.

[0012] Preferably, the hopper body is provided with a retaining edge along the circumference, the retaining edge is located above the scraper ring, and the inner diameter of the retaining edge is equal to the inner diameter of the scraper ring.

[0013] Preferably, the adjusting mechanism includes a counterweight ball movably disposed on the baffle, a first spring disposed on the baffle, and a pushing assembly disposed on the hopper body. The baffle has a through hole for the counterweight ball to pass through, and the inner wall of the through hole is provided with an elastic pad. The scraper ring has a locking groove for engaging with the counterweight ball. The end of the first spring away from the baffle is connected to the scraper ring. The first spring is used to pull the scraper ring to slide away from the discharge port of the hopper body. The weight of the counterweight ball is greater than the pulling force of the first spring. The pushing assembly is used to push the counterweight ball through the through hole.

[0014] Preferably, the pushing assembly includes a push plate slidably disposed above the retaining edge, a second spring disposed on the retaining edge, and a pulling member disposed on the hopper body. The sliding direction of the push plate is parallel to the sliding direction of the scraper ring. The counterweight ball is located between the retaining edge and the push plate. The second spring is disposed between the push plate and the retaining edge. The pulling member is used to pull the push plate to slide towards the retaining edge.

[0015] Preferably, the hopper for hoisting concrete pouring also includes a pair of sector teeth hinged to the hopper body, with a connecting rod coaxially connected to the sector teeth. The connecting rod rotatably passes through the hopper body. The pulling member includes a second connecting rope wound around the connecting rod. The end of the second connecting rope away from the connecting rod slides through the side guard and connects to the push plate. When the sector teeth rotate to open the discharge port of the hopper body, the connecting rod retracts the second connecting rope.

[0016] Preferably, the counterweight ball is provided with a third connecting rope, the end of the third connecting rope away from the counterweight ball slides through the push plate, and the end of the third connecting rope outside the push plate is provided with a buckle.

[0017] In summary, this application includes the following beneficial technical effects:

[0018] During material discharge, the steel pipe wrench is turned downwards. At this time, the steel pipe wrench pulls the first connecting rope, which in turn pulls the first drum to rotate and unwind the first connecting rope. During the material discharge process, if there is an emergency such as a worker standing under the hopper body that requires immediate closure of the hopper body's outlet, the worker can immediately press the operation button. The operation button controls the braking component to work, which drives the first drum to rotate and wind up the first connecting rope. The first connecting rope pulls the steel pipe wrench upwards, closing the hopper body's outlet. This minimizes problems caused by slow worker reaction or difficulty in turning the steel pipe wrench, and helps to close the hopper body's outlet in a timely manner in emergency situations.

[0024] The following is in conjunction with the appendix Figure 1-4 This application will be described in further detail.

[0025] This application discloses a hopper for hoisting and pouring concrete. (See also...) Figure 1 The hopper for hoisting concrete pouring includes a hopper body 1, a steel pipe wrench 2 hinged to the hopper body 1, and a sector tooth 17 hinged to the hopper body 1. Two support plates 22 are fixed relative to each other on the side of the hopper body 1 near the steel pipe wrench 2. A first drum 3 is rotatably arranged between the two support plates 22. The rotation axis of the first drum 3 is perpendicular to the depth direction of the hopper body 1 and parallel to the hinge axis of the steel pipe wrench 2. The first drum 3 is located above the steel pipe wrench 2. A first connecting rope 4 is wound on the first drum 3. The end of the first connecting rope 4 away from the first drum 3 is fixedly connected to the end of the steel pipe wrench 2 away from the discharge port of the hopper body 1. An operation button 5 is installed on the side of the hopper body 1 near the first drum 3. A braking assembly 6 is provided on the hopper body 1 to drive the first drum 3 to rotate and wind the first connecting rope 4. The operation button 5 is electrically connected to the braking assembly 6.

[0026] When discharging material, turn the steel pipe wrench 2 downwards. At this time, the steel pipe wrench 2 pulls the first connecting rope 4, and the first connecting rope 4 pulls the first drum 3 to rotate and unwind the first connecting rope 4. During the discharging process, if there is an emergency such as a worker standing under the hopper body 1 and the discharge port of the hopper body 1 needs to be closed urgently, the worker can immediately press the operation button 5. The operation button 5 controls the braking component 6 to work. The braking component 6 drives the first drum 3 to rotate and wind up the first connecting rope 4. The first connecting rope 4 pulls the steel pipe wrench 2 upwards. The upward rotation of the steel pipe wrench 2 can drive the sealing plate to close the discharge port of the hopper body 1, thereby minimizing problems caused by the worker's slow reaction and difficulty in turning the steel pipe wrench 2. This helps to close the discharge port of the hopper body 1 in time in case of an emergency. At the same time, the discharge flow rate of the hopper body 1 can be adjusted and fixed by adjusting the length of the first connecting rope 4.

[0027] Reference Figure 1To facilitate the rotation of the first drum 3 to wind up the first connecting rope 4, the braking assembly 6 includes a gear 61, a rack 62, and a drive member 63. The gear 61 is coaxially fixedly connected to the first drum 3. The rack 62 is slidably disposed on the outer wall of the hopper body 1 near the gear 61. The sliding direction of the rack 62 is perpendicular to the rotation axis of the first drum 3 and parallel to the depth direction of the hopper body 1. The rack 62 is used to mesh with the gear 61. The drive member 63 is disposed on the hopper body 1 and is electrically connected to the operation button 5. The drive member 63 is used to drive the rack 62 to slide and drive the gear 61 to rotate.

[0028] Reference Figure 1 To facilitate the sliding of the rack 62, the driving component 63 includes a cylinder 631, which is fixedly mounted on the outer wall of the hopper body 1. The extension and retraction direction of the cylinder 631 is parallel to the sliding direction of the rack 62. The rack 62 is fixedly connected to the piston rod of the cylinder 631, and the cylinder 631 is electrically connected to the operation button 5. In other embodiments, the cylinder 631 can be replaced by an electric cylinder, hydraulic cylinder, etc.

[0029] When material needs to be discharged, gear 61 and rack 62 are disengaged, allowing the first drum 3 to rotate and unwind the first connecting rope 4. When the operation button 5 is pressed, cylinder 631 is activated, driving rack 62 to move closer to gear 61, causing rack 62 to mesh with gear 61. This drives gear 61 and the first drum 3 to rotate, allowing the first drum 3 to wind up the first connecting rope 4. The first connecting rope 4 then pulls the steel pipe wrench 2 upwards, enabling the steel pipe wrench 2 to rotate in a timely manner in case of emergencies, facilitating the sealing plate to close the discharge port of the hopper body 1.

[0030] Reference Figure 1 A contact switch 7 is fixedly installed on the side of the hopper body 1 near the steel pipe wrench 2 for contacting the steel pipe wrench 2. The contact switch 7 is located below the first drum 3 and is electrically connected to the cylinder 631. When the steel pipe wrench 2 contacts the contact switch 7, the discharge port of the hopper body 1 is closed, and the contact switch 7 drives the cylinder 631 to stop working. This facilitates the operation of the cylinder 631, prevents the rack 62 from excessively moving, and helps to pull the steel pipe wrench 2 to the required position.

[0031] Reference Figure 2 and Figure 3The upper section of the hopper body 1 is cylindrical, and the lower section is a frustum. A scraper ring 8 is slidably installed inside the hopper body 1. The scraper ring 8 is located within the cylinder of the upper section of the hopper body 1, and its sliding direction is parallel to the depth direction of the hopper body 1. The outer wall of the scraper ring 8 abuts against the inner wall of the hopper body 1. An adjustment mechanism for adjusting the sliding of the scraper ring 8 is provided inside the hopper body 1. A retaining edge 9 is fixedly installed circumferentially on the top wall of the hopper body 1. The retaining edge 9 is located above the scraper ring 8, and its inner diameter is smaller than the diameter of the upper section of the hopper body 1, but equal to the inner diameter of the scraper ring 8. When concrete is poured into the hopper body 1, it is less likely to fall onto the scraper ring 8 due to the protection of the retaining edge 9.

[0032] Reference Figure 2 Inside the hopper body 1, there are two guide rods 23 that are fixed relative to each other. The length direction of the guide rods 23 is parallel to the sliding direction of the scraper ring 8. The scraper ring 8 is slidably sleeved on the two guide rods 23, and the guide rods 23 are configured to guide the sliding of the scraper ring 8.

[0033] Reference Figure 2 and Figure 3 To facilitate the adjustment of the sliding of the scraper ring 8, the adjustment mechanism includes a counterweight ball 10, a first spring 11, and a pushing assembly. The counterweight balls 10 are symmetrically and movably arranged on both sides of the retaining edge 9. In other embodiments, the number of counterweight balls 10 can be set as needed. Both the inner and outer rings of the retaining edge 9 are fixed with baffles 24. The baffles 24 are located above the retaining edge 9 and are arranged along the circumference of the retaining edge 9. The counterweight balls 10 are located on the retaining edge 9 between the two baffles 24. The retaining edge 9 has through holes 12 for the counterweight balls 10 to pass through. The through holes 12 correspond one-to-one with the counterweight balls 10. The diameter of the through holes 12 is adapted to the diameter of the counterweight balls 10. An elastic pad 13 is bonded to the inner wall of the counterweight balls 10. In this embodiment, the pad 13 is a rubber layer. In other embodiments, the pad 13 can be replaced with a plastic layer or a silicone layer. This makes it difficult for the counterweight balls 10 to fall out of the through holes 12 without external force. A limiting ring 25 is fixed on the retaining edge 9. The limiting ring 25 corresponds one-to-one with the through hole 12. The diameter of the limiting ring 25 is larger than the diameter of the through hole 12. The through hole 12 is located inside the corresponding limiting ring 25. The height of the limiting ring 25 is smaller than the radius of the counterweight ball 10, so that the counterweight ball 10 is located inside the corresponding limiting ring 25. A locking groove 14 is provided on the scraper ring 8 for engaging with the counterweight ball 10. The locking groove 14 corresponds one-to-one with the counterweight ball 10. The locking groove 14 is located in the same position as the through hole 12. The depth of the locking groove 14 is greater than the radius of the counterweight ball 10, so that the counterweight ball 10 is not easily separated from the scraper ring 8 after entering the locking groove 14.

[0034] Reference Figure 2 and Figure 3The first spring 11 is movably sleeved on the guide rod 23. One end of the first spring 11 is fixed to the bottom wall of the side 9, and the other end is fixed to the top wall of the scraper ring 8. The first spring 11 is used to pull the scraper ring 8 to slide away from the discharge port of the hopper body 1. The weight of the counterweight ball 10 is greater than the pulling force of the first spring 11. The sum of the weights of the counterweight ball 10 and the scraper ring 8 is less than the sum of the pulling force of the first spring 11 and the supporting force of the concrete on the scraper ring 8. The pushing component is set on the hopper body 1. The pushing component is used to push the counterweight ball 10 through the corresponding through hole 12.

[0035] Reference Figure 2 and Figure 3 To facilitate pushing the counterweight ball 10 through the corresponding through hole 12, the pushing assembly includes a push plate 15, a second spring 16, and a pulling member. The push plate 15 is slidably disposed above the baffle 9, and the sliding direction of the push plate 15 is parallel to the sliding direction of the scraper ring 8. The push plate 15 is located between the two baffles 24 and is arranged along the circumference of the baffle 9. The counterweight ball 10 is located below the push plate 15. The second spring 16 is fixedly disposed between the baffle 9 and the push plate 15. Multiple second springs 16 are provided and are distributed at intervals along the circumference of the baffle 9. The extending direction of the second spring 16 is parallel to the sliding direction of the push plate 15.

[0036] Reference Figure 2 and Figure 4 A pair of sector teeth 17 are provided on opposite sides of the hopper body 1. Pulling members are provided on the hopper body 1. Pulling members are used to pull the push plate 15 to slide towards the sidewall 9. A connecting rod 18 is coaxially fixedly connected to the sector teeth 17. The connecting rod 18 is rotatably inserted through the hopper body 1. The rotation axis of the connecting rod 18 is parallel to the hinge axis of the steel pipe wrench 2. The connecting rod 18 is located below the guide rod 23.

[0037] See 3 and Figure 4 A second drum 26 is fixedly sleeved at one end of the connecting rod 18 inside the hopper body 1. The pulling component includes a second connecting rope 19, which is wound around the second drum 26. The end of the second connecting rope 19 away from the connecting rod 18 slides sequentially through the scraper ring 8 and the retaining edge 9 and connects to the bottom wall of the push plate 15. When the sector tooth 17 rotates to open the discharge port of the hopper body 1, the second drum 26 winds up the second connecting rope 19. Guide pulleys 27 are fixedly installed on the inner wall of the hopper body 1. The guide pulleys 27 correspond one-to-one with the second connecting ropes 19. The second connecting ropes 19 between the push plate 15 and the second drum 26 slide and overlap on the corresponding guide pulleys 27.

[0038] When the hopper body 1 is initially filled with concrete, the scraper ring 8 approaches the retaining edge 9 under the action of the first spring 11. The scraper ring 8 is located above the concrete, and the counterweight ball 10 is located above the corresponding through hole 12. The limiting ring 25 limits the counterweight ball 10. When the sector tooth 17 rotates and the sealing plate opens the outlet of the hopper body 1, the concrete in the hopper body 1 is gradually moved out for pouring. The sector tooth 17 drives the second drum 26 to rotate through the connecting rod 18 to wind up the second connecting rope 19. The second connecting rope 19 pulls the push plate 15 to slide towards the retaining edge 9, compressing the second spring 16. The push plate 15 presses against the through hole 12. The counterweight ball 10 is squeezed, causing it to fall through the through hole 12 into the corresponding locking groove 14 of the scraper ring 8. At this time, the weight of the scraper ring 8 increases, driving it to move downward. Since the outer wall of the scraper ring 8 abuts against the inner wall of the upper section of the hopper body 1, it can scrape off the concrete adhering to the inner wall of the hopper body 1, improving the discharge effect. When the scraper ring 8 moves down onto the concrete, since the sum of the weights of the counterweight ball 10 and the scraper ring 8 is less than the sum of the tension of the first spring 11 and the supporting force of the concrete on the scraper ring 8, the scraper ring 8 can gradually descend as the concrete is removed, ensuring that it does not sink into the concrete and ensuring the scraping effect.

[0039] Reference Figure 2 and Figure 3 A third connecting rope 20 is fixedly connected to the counterweight ball 10. The end of the third connecting rope 20 away from the counterweight ball 10 slides through the push plate 15. A buckle 21 is fixed to the end of the third connecting rope 20 outside the push plate 15.

[0040] After all the concrete has been removed, the sector tooth 17 rotates, causing the sealing plate to close the discharge port of the hopper body 1. At the same time, the connecting rod 18 drives the second drum 26 to rotate, and the second drum 26 unwinds the second connecting rope 19. At this time, the compressed second spring 16 pushes the push plate 15 to move away from the side 9 to reset. By pulling the buckle 21 located outside the push plate 15, the counterweight ball 10 can be lifted. At this time, the stretched first spring 11 pulls the scraper ring 8 upward to reset. Then the counterweight ball 10 passes through the through hole 12 and is located above the through hole 12 for easy use next time.

[0041] The implementation principle of this application embodiment is as follows: In the initial state, the buckle locks the steel pipe wrench 2, and the first drum 3 is rotated to make the first connecting rope 4 tensioned; when unloading, the buckle is opened and the steel pipe wrench 2 is rotated downward. At this time, the steel pipe wrench 2 pulls the first connecting rope 4, and the first connecting rope 4 pulls the first drum 3 to rotate and unwind the first connecting rope 4. During the unloading process, when there is an emergency such as a worker standing under the hopper body 1 and the discharge port of the hopper body 1 needs to be closed urgently, the worker immediately presses the operation button 5. The operation button 5 drives the cylinder 631 to work. The cylinder 631 drives the rack 62 to slide towards the gear 61, driving the gear 61 and the first drum 3 to rotate. When the first drum 3 rotates, it winds up the first connecting rope 4. The first connecting rope 4 immediately pulls the steel pipe wrench 2 upward, causing the steel pipe wrench 2 to drive the sealing plate to close the discharge port of the hopper body 1 until the steel pipe wrench 2 comes into contact with the contact switch 7. The contact switch 7 then drives the cylinder 631 to stop working, thus minimizing problems caused by slow reaction or difficulty in turning the steel pipe wrench 2. Then, the steel pipe wrench 2 can be locked with a buckle. Then, the operation button 5 is pressed, causing the cylinder 631 to drive the rack 62 to move in the opposite direction and disengage from the gear 61. This helps to close the discharge port of the hopper body 1 in a timely manner in case of an emergency. At the same time, the discharge flow rate of the hopper body 1 can also be adjusted and fixed.

[0042] It should be noted that the configuration of the hopper body 1, steel pipe wrench 2, sealing plate, fastener and sector tooth plate 17 mentioned in this application is the same as that in related technologies, and will not be described in detail here.

[0043] 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.
