In a better embodiment of the present utility model, retardation controller comprises a cylindrical housings, and the axis horizontal of described cylindrical housings arranges and is fixed in vertical transfer passage, is provided with the impeller around horizontal axis in described cylindrical housings; Be positioned in the cylindrical housings above impeller, be provided with the biased upper shed being positioned at side directly over wheel rotation axis; The cylindrical housings be positioned at below impeller is provided with under shed.
In a better embodiment of the present utility model, cylindrical housings is by the cross section shutoff of transfer passage, and the described upper shed in cylindrical housings and under shed form the dropping channel that concrete is passed.
In a better embodiment of the present utility model, be fixed with motor in one end of cylindrical housings, the rotating shaft of described motor and the coaxial of impeller and with impeller synchronous axial system; Described motor connects an energy consumption brake.
In a better embodiment of the present utility model, container containing is the bulk containers of bottom end closure, upper end open.
From the above mentioned, this slow descending device, by arranging bulk containers and retardation controller in vertical transfer passage, receives the safety problem of concrete transport vehicles, and ensures the concrete quality that high-altitude is carried downwards when guaranteeing the downward delivering concrete in high-altitude.
Accompanying drawing explanation
The following drawings is only intended to schematically illustrate the utility model and explain, does not limit scope of the present utility model.Wherein:
Fig. 1: be the structural representation of the utility model slow descending device.
Detailed description of the invention
In order to there be understanding clearly to technical characteristic of the present utility model, object and effect, now contrast accompanying drawing and detailed description of the invention of the present utility model is described.
As shown in Figure 1, the utility model provides the slow descending device 10 of the downward delivering concrete in a kind of high-altitude, and slow descending device arranges 10 in a vertical transfer passage 1, and concrete a is fallen by transfer passage 1, and the effect through slow descending device 10 makes its falling speed slow down.Slow descending device 10 comprises open topped and can accept a certain amount of concrete container containing 2, container containing 2 is fixedly installed in transfer passage 1, the concrete fallen can fall in this container containing 2, when filling concrete a in this container containing 2, the concrete overflowed can by the landing downwards of the space 3 between container containing 2 and transfer passage 1, and in present embodiment, container containing 2 adopts the bulk containers of bottom end closure, upper end open.Be positioned at the position of container containing 2 bottom certain distance in transfer passage 1, be provided with the retardation controller that concrete falling speed is slowed down.Concrete, this retardation controller comprises a cylindrical housings 4, and the axis horizontal of cylindrical housings 4 arranges and is fixed in vertical transfer passage 1, and namely the axis of cylindrical housings 4 is vertical with transfer passage 1.The impeller 5 around horizontal axis is provided with in cylindrical housings 4; Be positioned in the cylindrical housings 4 above impeller 5, be provided with the biased upper shed 41 being positioned at side directly over wheel rotation axis, this upper shed 41 departs from directly over wheel rotation axis and arranges, and impeller 5 can be made only to rotate towards a direction under the concrete effect in whereabouts; The cylindrical housings 4 be positioned at below impeller 5 is provided with under shed 42, and under shed 42 can be positioned at the below of upper shed 41 the same side, immediately below also can being located at or be located at the below of upper shed 41 opposite side.Wherein, cylindrical housings 4 is by the cross section shutoff of transfer passage 1, and the upper shed 41 in cylindrical housings 4 and under shed 42 form the dropping channel that concrete is passed.
Further, be fixed with motor 6 in one end of cylindrical housings 4, motor 6 is positioned at the outside of transfer passage 1, the rotating shaft of motor 6 and the coaxial of impeller 5 and with impeller 5 synchronous axial system; This motor 6 can connect the AC power of 380V, and motor 6 connects an energy consumption brake 7.Energy consumption brake 7 can adopt the energy consumption brake that in prior art, motor uses, in present embodiment, energy consumption brake 7 makes it brake by inputting a direct current to motor, and can by the rotating speed regulating its size of current to change motor, the rotating speed of synchronous adjustment impeller, thus control concrete flow velocity.
Slow descending device 10 of the present utility model operationally, first the concrete fluid fallen in transfer passage 1 falls in bulk containers 2, the concrete fallen again can be fallen on the concrete that first falls, speed will slow down, because concrete has very large buoyancy, also can slow down impact force, ensure that bulk containers 2 can not be damaged.After bulk containers filled by concrete, the concrete of spilling can by the space 3 between bulk containers 2 and transfer passage 1 with the downward landing of low speed.The concrete of downward landing can flow on the retardation controller of bottom, the upper shed 41 of concrete through cylindrical housings 4 side enters in cylindrical housings, impeller 5 rotates under the percussion of concrete gravity, impeller 5 drive motor 6 rotates, the rotating speed of motor 6 can be slowed down by the energy consumption brake 7 be connected with motor 6, thus slow down the rotating speed of impeller 5, the rotating speed of adjustable motor 6 simultaneously, thus control speed and the flow of concrete whereabouts, when motor 6 stops operating, impeller 5 also stops operating, and now concrete dropping channel is closed and stops falling.When whereabouts pathway closure overlong time blocks, motor 6 connects the AC power actuating motor of 380V, and motor 6 impeller 5 is rotated, and the concrete promoting to stagnate falls, and in turn ensure that and can not block while guarantee concrete amount.
According to the length of transfer passage 1, many this slow descending devices 10 of group can be set in transfer passage 1; By calculating, the distance of every 50 meters of drops arranges the safety that a set of slow descending device 10 just can ensure concrete quality and haulage vehicle.
From the above mentioned, this slow descending device, by arranging bulk containers and retardation controller in vertical transfer passage, receives the safety problem of concrete transport vehicles, and ensures the concrete quality that high-altitude is carried downwards when guaranteeing the downward delivering concrete in high-altitude.
The foregoing is only the schematic detailed description of the invention of the utility model, and be not used to limit scope of the present utility model.Any those skilled in the art, equivalent variations done under the prerequisite not departing from design of the present utility model and principle and amendment, all should belong to the scope of the utility model protection.
