Technical Field

[0001] This utility model relates to the field of concrete unloading technology, and in particular to an unloading device for roller-compacted concrete used in the construction of a storage power station reservoir. Background Technology

[0002] Roller-compacted concrete dams are highly favored in the dam construction industry due to their simple dam structure and fast construction speed. With the continuous development of demand and technology, the height and volume of dams are increasing, and the requirements for construction period and safety are becoming more stringent. Continuous pouring during high-temperature seasons and periods is not uncommon. After the concrete leaves the mixing plant, it needs to be transported to the pouring site quickly. During transportation, aggregate segregation, grout leakage, and severe bleeding must be avoided. Transportation time should be minimized, the number of transfers reduced, and the generation of waste from the initial set concrete reduced.

[0003] However, existing roller-compacted concrete unloading devices lack a device for filtering the initial set concrete waste. If unfiltered concrete waste is used to produce concrete dams, the large-diameter aggregates in it will reduce the strength and durability of the dam body. Utility Model Content

[0004] Given that existing roller-compacted concrete unloading devices lack a device for filtering the initial set concrete waste, and that unfiltered concrete waste, if used to produce concrete dams, would reduce the strength and durability of the dam body due to the large-diameter aggregates, this utility model was proposed.

[0005] To solve the above-mentioned technical problems, this utility model provides the following technical solution: a discharge device for roller-compacted concrete in the construction of a pumped storage power station reservoir, comprising a discharge cylinder, a discharge trough extending through the inner wall of the middle end of the discharge cylinder, a filter plate inserted into the inner wall of the discharge cylinder at the lower end of the discharge trough, sliders at both ends of the filter plate, a sliding groove cooperating with the sliders on the inner wall of the discharge cylinder, a spring at the lower end of the sliders, two sets of symmetrical guide plates at the lower end of the inner wall of the discharge cylinder, a discharge port at the lower end of the discharge cylinder, a pusher plate on one side of the upper end of the filter plate, a push rod at one end of the pusher plate, and a cylinder on the outer wall of the discharge cylinder.

[0008] As a preferred embodiment of the unloading device for roller-compacted concrete used in the construction of a storage power station reservoir according to the present invention, wherein the guide plate is inclined from top to bottom toward the discharge port.

[0012] Compared with the prior art, the present invention has at least the following beneficial effects:

[0013] 1. In this utility model, the concrete at the top of the unloading cylinder falls onto the top of the filter plate through the discharge chute. Under the action of the concrete's gravity, the filter plate slides down the chute through the slider and compresses the spring. Under the reverse elastic force of the spring, the filter plate bounces up again. Thus, as the concrete continues to fall through the discharge chute, the filter plate vibrates up and down continuously, which accelerates the filtration rate of concrete waste.

Thus, the concrete at the top of the discharge cylinder can be filtered through the discharge chute. During this process, the motor rotates, which drives the bidirectional lead screw to rotate. The bidirectional lead screw drives the stirring rod to rotate. Stirring can slow down the initial setting rate of the concrete and reduce the generation of waste from the initial set concrete.

[0020] To make the above-mentioned objectives, features and advantages of this utility model more apparent and understandable, the specific embodiments of this utility model will be described in detail below with reference to the accompanying drawings.

[0021] Example 1

[0022] Reference Figure 1 and Figure 2 This is the first embodiment of the present invention, which provides a material unloading device for roller-compacted concrete in the construction of a storage power station reservoir. The device includes an unloading cylinder 1, a discharge trough 4 extending through the inner wall of the middle end of the unloading cylinder 1, a filter plate 5 inserted into the lower end of the discharge trough 4 on the inner wall of the unloading cylinder 1, sliders 6 at both ends of the filter plate 5, a sliding groove that cooperates with the sliders 6 on the inner wall of the unloading cylinder 1, a spring 7 at the lower end of the sliders 6, two sets of symmetrical guide plates 8 at the lower end of the inner wall of the unloading cylinder 1, a discharge port 9 at the lower end of the unloading cylinder 1, a pusher plate 10 on one side of the upper end of the filter plate 5, a push rod 11 at one end of the pusher plate 10, and a cylinder 12 on the outer wall of the unloading cylinder 1.

[0023] The upper and lower ends of the spring 7 are fixedly connected to the lower end of the slider 6 and the bottom end of the groove, respectively. Therefore, the filter plate 5 is set in a V shape. The pusher plate 10 and the upper surface of the filter plate 5 are in contact. The pusher rod 11 moves through the inner wall of the unloading cylinder 1. The extended end of the cylinder 12 is fixedly connected to the end of the pusher rod 11 away from the pusher plate 10. The outer wall of the unloading cylinder 1 is provided with a waste trough 13 at the end away from the pusher plate 10. The guide plate 8 is inclined from top to bottom towards the discharge port 9.

[0024] When concrete needs to be unloaded, the concrete at the top of the unloading cylinder 1 falls onto the top of the filter plate 5 through the discharge chute 4. Under the action of the concrete's gravity, the filter plate 5 slides down the chute through the slider 6 and compresses the spring 7. Under the reverse elastic force of the spring 7, the filter plate 5 bounces up again. Thus, as the concrete continues to fall through the discharge chute 4, the filter plate 5 vibrates up and down, accelerating the filtration rate of the concrete waste. The concrete filtered by the filter plate 5 is discharged from the unloading cylinder 1 through the discharge port 9 by the guide plate 8. The partially set concrete waste is intercepted at the top of the filter plate 5. After unloading, the filter plate 5 tends to stabilize. At this time, the cylinder 12 is activated to retract, and the push rod 11 pushes the pusher plate 10 to slide along the top of the filter plate 5, pushing the waste at the top of the filter plate 5 towards the waste chute 13. The waste is discharged from the unloading cylinder 1 through the waste chute 13, and the workers can process the waste discharged from the waste chute 13.

[0025] Example 2

[0026] Reference Figures 1-3 This is the second embodiment of the present invention. The difference between this embodiment and the first embodiment is that: a motor 2 is provided at the upper end of the unloading cylinder 1, and an adjustment component 3 is provided at the output end of the motor 2. The adjustment component 3 includes a bidirectional lead screw 31 provided at the output end of the motor 2. A protective plate 32 is fixedly provided on the upper side of the middle end of the unloading cylinder 1, and the bidirectional lead screw 31 moves through the protective plate 32.

[0027] The outer wall of the bidirectional lead screw 31 located in the inner cavity of the protective plate 32 is movably fitted with two sets of symmetrical ball screw sleeves 33. The outer wall of the bidirectional lead screw 31 located in the inner cavity of the protective plate 32 is provided with bidirectional threads that cooperate with the ball screw sleeves 33. The outer wall of the ball screw sleeves 33 is hinged with two sets of symmetrical adjusting rods 34. The outer walls of both ends of the protective plate 32 are movably inserted with two sets of symmetrical connecting rods 35. The end of the adjusting rod 34 away from the ball screw sleeve 33 is hinged to the connecting rod 35.

[0028] A sealing plate 36 is fixedly provided at the end of the connecting rod 35 away from the adjusting rod 34. The lower end face of the sealing plate 36 and the upper end face of the discharge chute 4 are on the same horizontal plane.

[0029] When concrete needs to be unloaded, the motor 2 is started to drive the bidirectional lead screw 31 to rotate. The bidirectional lead screw 31 drives the ball screw sleeve 33 to slide along the outer wall of the bidirectional lead screw 31. The two sets of ball screw sleeves 33 move away from each other. The ball screw sleeve 33 drives the adjusting rod 34 to rotate at a certain angle. The included angle between the adjusting rod 34 and the ball screw sleeve 33 decreases. The connecting rod 35 slides along the outer wall of the protective plate 32 and moves closer to each other. The sealing plate 36 gradually moves out from the upper end of the discharge chute 4. Thus, the concrete at the upper end of the unloading cylinder 1 can be filtered through the discharge chute 4. During this process, the motor 2 rotates to drive the bidirectional lead screw 31 to rotate. The bidirectional lead screw 31 drives the stirring rod to rotate. Stirring can slow down the initial setting rate of the concrete and reduce the generation of waste from the initial set concrete.

[0030] The remaining structure is the same as that in Example 1.
