Description

Quick positioning pipe hoop for pumping concrete blocking pipe

Technical Field

The utility model belongs to the building engineering field, concretely relates to ferrule with stifled quick positioner of pipe.

Background

During the construction of super high rise concrete structure buildings, concrete is pumped to the construction floor, usually through long fixed pipes. If pipe blockage occurs in the pumping process, the traditional solution is to knock the pump pipe section by section and judge the position of the pipe blockage according to the change of sound. However, under the condition of large pumping height, the method of knocking section by section wastes time and labor, and the time for detaching the pipe for rescue is easy to delay; once the concrete in the pump pipe is initially set, all the pump pipes may be scrapped; the pump pipe is completely removed and reinstalled, so that the construction site is shut down, and not little economic loss is caused; for some construction projects needing to be poured once, the construction quality of the building can be affected even if pouring is interrupted, and the life and property safety of people is threatened.

SUMMERY OF THE UTILITY MODEL

In order to solve the problem of stifled pipe back choking point location difficulty of pump sending concrete, the utility model provides a pump sending concrete fixes a position the ferrule fast, and this ferrule can take place the interval at back fast instruction choking point place at stifled pipe, guides constructor to take remedial action. The technical scheme is as follows:

a pumping concrete pipe plugging quick positioning pipe hoop comprises a pipe hoop main body and is characterized in that a detection unit is led out of the pipe hoop main body and comprises a filter screen, a sleeve, a piston, a vent pipe, a one-way valve and a sleeve ring, the sleeve is fixed on the pipe hoop main body, two ends of the inner wall of the sleeve are provided with limiting devices, the filter screen is arranged between the inner cavity of the sleeve and the inner cavity of the pipe hoop main body, the piston is formed by connecting two cylinders with different diameters, the thick end of the piston is positioned in the sleeve, the diameter of the thick end is matched with the inner diameter of the sleeve, and the thin end extends out of the sleeve; the lantern ring is sleeved at the thin end of the piston, the thin end can retract into the piston when the piston moves inwards, and the lantern ring does not move along with the piston when the thin end of the piston moves inwards; the vent pipe is communicated with two points on a bus of the sleeve wall, the distance of which is greater than the length of the thick end of the piston, and a one-way valve is arranged in the vent pipe and only allows air to flow from one end far away from the pump pipe to one end close to the pump pipe.

The utility model has the advantages that:

(1) discharging concrete below the plugging point at the first time to prevent the concrete from initially setting in the pipe;

(2) the interval of the plugging point is quickly indicated, the inspection range is greatly reduced, the repairing time is shortened, and the probability of initial setting of the concrete above the plugging point in the pipe is reduced.

Drawings

Fig. 1 is a cross-sectional view of a detection unit of a pipe clamp according to an embodiment of the present invention.

In fig. 1, 1 is a filter screen, 2 is a sleeve, 3 is a piston, 4 is a vent pipe, 5 is a check valve, 6 is a lantern ring, 7 is a safety rope, and 8 is a pipe hoop main body wall.

Detailed Description

In order to clearly illustrate the technical features of the present solution, the present solution is described below by using a specific embodiment and with reference to the attached drawings.

In fig. 1, a filter screen 1 is disposed between the inner cavity of the pipe hoop body and the inner cavity of the sleeve to prevent aggregate in concrete from entering the detection unit. The sleeve 2 is fixed in the middle of the wall of the pipe hoop main body, the piston 3 can slide in the sleeve, and two ends of the inner cavity of the sleeve are provided with limiting devices for the piston 3. The vent pipe 4 is communicated with two points on the generatrix of the sleeve wall, the distance of which is greater than the length of the thick end of the piston, and a one-way valve 5 is arranged in the vent pipe 4 and only allows air to flow from one end far away from the pump pipe to one end close to the pump pipe. The lantern ring 6 is sleeved at the thin end of the piston, one end of the safety rope 7 is connected with the lantern ring 6, and the other end of the safety rope is connected with any other part of the pipe hoop so as to ensure safety.

During normal pumping, the piston 3 is positioned at one end, far away from the pump pipe, in the sleeve 2, the one-way valve 5 is in a closed state, and the lantern ring 6 is sleeved at the thin end of the piston.

When a pipe is blocked, the pump machine is operated to perform reverse pumping, negative pressure is firstly generated at the first pipe hoop below the blocking point, the one-way valve 5 is opened, and the piston 3 moves towards the pump pipe under the action of atmospheric pressure; when the thin end of the piston completely enters the sleeve 2, the lantern ring falls off, and constructors can observe that the plugging point is located in the interval between the pipe hoop with the falling lantern ring 6 and the first pipe hoop above the pipe hoop; when the thick end of the piston moves to a position between two points connected with the vent pipe 4, outside air rushes into the pump pipe to eliminate negative pressure, so that concrete below the pipe hoop can be discharged downwards; the pumping is recovered after the fault is eliminated, the one-way valve 5 is closed and the piston 3 is reset under the pumping pressure; the collar 6 is manually repositioned by the operator for the next use.

This embodiment is provided with a safety rope as a preferred embodiment. If a safety line is not used, a choke point can also be detected when the collar is dropped.
