Abstract
The utility model discloses a buffering device for a concrete sliding chute. Two ends of a buffering pipe are in welded connection with an upper flange and a lower flange respectively; and a U-shaped buffering section is arranged on the buffering pipe. By the arrangement of the U-shaped reducer pipes on the sliding chute every other 40 meters, the falling speed of concrete is buffered, so that concrete aggregate is effectively protected from separation; by the adoption of the structure that the diameter of the upper opening of the buffering pipe is smaller than the diameter of the lower opening of the buffering pipe, the blockage rate of the concrete in the buffering pipe can be effectively reduced; a hole is formed in a blocked pipe, so that the buffering pipe is dredged in case of blockage; and in virtue of the arrangement of the upper flange and the lower flange, the buffering pipe can be conveniently replaced after being worn out.
Description
Technical field
The utility model relates to a kind of concrete elephant trunk device, especially a kind of concrete elephant trunk buffering safeties.
Background technology
At present, usually adopt the elephant trunk delivering concrete during long inclined shaft underground chamber concreting, because inclined shaft is long and steep, concrete carries slide speed very fast downwards from the mouth of pipe, it is serious to cause concrete aggregate to separate, and workability is relatively poor, not only influences concrete pouring quality, and elephant trunk is easy to by concrete material worn outly, influences application life of elephant trunk.
Summary of the invention
Technical problem to be solved in the utility model provides a kind of concrete elephant trunk buffer, can prevent effectively that concrete aggregate from separating, and can prolong the application life of transmission and concrete transmission elephant trunk.
For solving the problems of the technologies described above, the technical scheme that the utility model adopted is: a kind of concrete elephant trunk buffer, and the separator tube two ends are welded to connect with upper flange and lower flange respectively, and described separator tube is provided with " U " shape breeze way.
" U " shape breeze way on the described separator tube is a horizontally set.
Described separator tube is a reducer pipe, and the diameter of separator tube upper opening is less than the diameter of lower openings.
Described separator tube is provided with plugging and handles the hole, and plugging is handled the hole and is provided with the processing blind patch.
Described processing blind patch is connected with separator tube by bolt.
Described plugging processing hole is positioned on the separator tube to be located gently near the top of " U " shape bottom.
A kind of concrete elephant trunk buffer that the utility model provides, by on elephant trunk every " U " of about 40 meters settings shape reducer pipe, cushioned concrete falling speed, thereby prevented that effectively concrete aggregate from separating; Owing to adopt the structure of the diameter of separator tube upper opening, can effectively reduce the probability that concrete stops up in separator tube less than the diameter of lower openings; The hole is handled in the plugging that is provided with, and is convenient to when occurring stopping up separator tube be dredged; Upper flange that is provided with and lower flange are convenient to change after the separator tube wearing and tearing.
Description of drawings
The utility model is described in further detail below in conjunction with drawings and Examples.
Fig. 1 is a structural representation of the present utility model.
Fig. 2 is the A-A view of Fig. 1.
The specific embodiment
In Fig. 1, Fig. 2, a kind of concrete elephant trunk buffer, separator tube 2 two ends are welded to connect with upper flange 1 and lower flange 3 respectively, are convenient to like this change after separator tube 2 damages, and described separator tube 2 is provided with " U " shape breeze way.
" U " shape breeze way on the described separator tube 2 is a horizontally set.
Described separator tube 2 is a reducer pipe, and the diameter of separator tube 2 upper openings is less than the diameter of lower openings, thereby can effectively reduce the probability that concrete stops up in separator tube.
Described separator tube 2 is provided with plugging and handles hole 4, and plugging is handled hole 4 and is provided with processing blind patch 5.
Described processing blind patch 5 is connected with separator tube 2 by bolt.
Described plugging processing hole 4 is positioned on the separator tube 2 locates the operation when being convenient to dredge so gently near the top of " U " shape bottom.
Using method of the present utility model is as follows:
1, (the elephant trunk external diameter that adapts with the utility model is diameter 219mm when long inclined shaft transmission and concrete transmission elephant trunk is installed, if use the elephant trunk of various outer diameter, then make and connect this device that bore is complementary), every about 40 meters, install this device additional, at elephant trunk lowermost end (being elephant trunk discharging opening place) this device is installed, has so just been finished the installation of long inclined shaft transmission and concrete transmission elephant trunk.
When 2, this device was connected with elephant trunk, lower openings was that the larger caliber section is positioned at the bottom, was connected firmly by bolt with adjacent reducing elephant trunk.
3, at concrete in course of conveying, if any concrete plugging phenomenon takes place, open this moment and handle blind patch 5, utilize the plugging that is provided with herein to handle hole 4 and carry out artificial treatment and get final product.
