Abstract
A large-drop-height vertical concrete delivery descent control device comprises a feeding pipe and a discharging pipe, wherein the feeding pipe and the discharging pipe are oppositely connected, a side protective plate is welded and fixed between two pipes, a feeding port is formed in the upper end of the feeding pipe, a discharging port is formed in the lower end of the discharging pipe, a feeding reducer pipe is fixedly welded on the inner wall of the feeding pipe, side wall reinforcing ribs are fixedly welded on the side wall of the discharging pipe, and a buffer base plate is arranged at the bottom of the feeding pipe. The feeding reducer pipe is fixedly welded on the inner wall of the feeding pipe, so that the pipe diameter is decreased, and the concrete descending speed is reduced. Longitudinal and transverse reinforcing ribs on the base plate block concrete materials and enable the concrete materials to stay on the base plate within a short period of time, continuous blanking enables concrete on the base plate to be hit, and follow-up descending concrete is buffered and then impacts the right side pipe wall, the moving direction of the concrete is changed through multiple-time buffering, the concrete collides, extrudes and finally is mixed in a buffer, the speed is reduced, aggregate separation is reduced, and the concrete peaceability is improved.
Description
Technical field
The utility model relates to a kind of novel used in vertical transportation of concrete device, and being specifically related to a kind of large drop is a kind of used in vertical transportation of concrete descending lifeline.
Background technology
The design and construction of descending lifeline is the important step of used in vertical transportation of concrete.My-Box descending lifeline, the negative pressure elephant trunks etc. of adopting in the large drop concrete construction of vertical drop more than 20m at present more.Various devices have its applicable advantage above, also have the shortcoming that self is difficult to overcome, and in the situation that on the applicable slope of negative pressure elephant trunk, storehouse face is larger, arrange, restricted to vertical transport; My-Box is developed by Japanese Qian Tian Co., Ltd., and technology is more ripe, can effectively prevent Segregation, improve workability, but weight is larger, each about 300kg, and complex structure, and maintenance difficult, expensive, cost is higher.
Summary of the invention
The purpose of this utility model be to provide a kind of with low cost, keep in repair easy large drop concrete vertical conveying descent control device, this descending lifeline can reach the flow velocity that reduces concrete vertical drop, guarantees the object of concrete workability.
The purpose of this utility model is achieved through the following technical solutions: a kind of concrete vertical conveying descent control device, comprise feed pipe and discharge nozzle, feed pipe is connected relatively with discharge nozzle, staggering in center, between two pipes, is welded with side guard board, and feed pipe upper end offers charging aperture, discharge nozzle lower end offers discharging opening, the fixing welding of inwall charging reducer pipe at feed pipe is fixedly welded with sidewall reinforcing muscle on discharge nozzle sidewall, in feed pipe bottom, is provided with buffering base plate.
On described buffering base plate, be welded with cross reinforcing and the waling of horizontal and longitudinal cross arrangement.
Discharge nozzle upper end offers cover plate-door.
Described charging reducer pipe is screw-thread steel, is fixed on feed pipe inwall between homogeneous phase.
The large drop concrete vertical conveying descent control device that the utility model provides, by be provided with the structure of charging reducer pipe at feed pipe inwall, diminishes pipe diameter, has reduced concrete falling speed; On base plate, be welded with longitudinally and cross reinforcing has stopped concrete material, the concrete material short time is rested on base plate, continuing blanking will impact on the concrete of base plate, after the concrete of follow-up decline is cushioned, impact discharge nozzle right side tube wall, right side tube wall is also welded with reinforcing bar to alleviate the wearing and tearing of right side tube wall.Concrete, through the buffering of the feed pipe left side mouth of pipe, left-side bottom and discharge nozzle right side tube wall, changes the direction of motion, and concrete aggregate downthrust in snubber finally mixes again, and Speed Reduction, has reduced the separation of aggregate, has improved concrete workability.Discharge nozzle upper end offers cover plate-door, the processing while being convenient to concrete material accumulation occurs.

The specific embodiment
Structure of the present utility model is as Figure 1-5: a kind of concrete vertical conveying descent control device, descending lifeline comprises feed pipe 1 and discharge nozzle 2, feed pipe 1 is connected relatively with discharge nozzle 2, staggering in center, is welded with side guard board 3 between two pipes, and feed pipe 1 upper end offers charging aperture 4, discharge nozzle 2 lower ends offer discharging opening 5, the fixing welding of inwall charging reducer pipe 6 at feed pipe 1 is fixedly welded with sidewall reinforcing muscle 7 on discharge nozzle 2 sidewalls, is provided with buffering base plate 8 in feed pipe 1 bottom.On described buffering base plate 8, be welded with cross reinforcing 10 and waling 11 that the employing screw-thread steel of horizontal and longitudinal cross arrangement is made.Discharge nozzle 2 upper ends offer cover plate-door 9.Described charging reducer pipe is screw-thread steel, is fixed on feed pipe inwall between homogeneous phase.
The new novel manufacturing process of this practicality is as follows: feed pipe 1 and discharge nozzle 2 adopt Φ 219mm, the common steel tube of wall thickness 6mm is made, first two 75cm are long, the steel pipe of diameter of phi 219mm respectively gas cutting becomes " 7 " font, in pipe, be welded with indented bars as charging reducer pipe 6 and sidewall reinforcing muscle 7, two pipes connect relatively, stagger in center, then with the thick common A3 steel plate of two 10mm, as the backplate of both sides, connect and weld, it is side guard board 3, due to the base plate 8 load maximum that withstands shocks, therefore base plate adopts the hardness that 20mm is thick high, the good high manganese steel sheet firm welding of anti-wear performance, on it, be welded and fixed cross reinforcing 10 and the waling 11 of alternate cross arrangement.
Operating principle of the present utility model is as shown in Figure 6: concrete material enters into descending lifeline by charging aperture, owing to being provided with the structure of charging reducer pipe at feed pipe 1 inwall, pipe diameter is diminished, reduced concrete falling speed, the concrete material declining drops on base plate 8, on base plate 8, the cross reinforcing 10 of welding and waling 11 can produce barrier effect to concrete material, the concrete material short time is rested on base plate 8, continuing blanking will impact on the concrete of base plate 8, after being cushioned, the concrete of follow-up decline impacts the right side tube wall of discharge nozzle 2, right side tube wall is also welded with reinforcing bar and makes sidewall reinforcing muscle 7, to alleviate the wearing and tearing of right side tube wall.Concrete is through the buffering of the feed pipe 1 left side mouth of pipe, left-side bottom and discharge nozzle 2 right side tube walls, change the direction of motion, concrete aggregate downthrust in snubber finally mixes again, Speed Reduction, reduce the separation of aggregate, improved concrete workability.Discharge nozzle 2 upper ends offer cover plate-door 9, the processing while being convenient to concrete material accumulation occurs.
