Description

(54) DEVICE FOR PRESSURE

SHUTTLE STAINTS

The invention relates to mine construction, in particular, to the sinking of shafts using forced immersion support.

A device for squeezing the supporting shafts of a shaft shaft is known, which includes an end cap, cantilever type stops rigidly embedded in the end cap, and power cylinders 1.

The disadvantage of such a device is the transfer of a large bending moment to the end cap, and since the concrete does not work well for bending, a large amount of metal is required to reinforce the end cap.

The closest to the technical aspect and the achieved result to the proposed is with a device for squeezing the supporting lining of the shaft shaft, including the end cap, pivotally attached to it stops and power cylinders 2.

In the known device, the moment is not transmitted to the head, but the head is tensioned, therefore the proportion of metal in the head is large, and this metal is not wrapped. In addition, the device is characterized by a high metal content of resistant structures.

The purpose of the invention is to reduce the metal consumption of the device.

The goal is achieved by the fact that the device, including its base, catcher, arrests and power cylinders hinged on it, is equipped with flexible elements that are missed under the end of the end cap, and supporting plates placed on the near-stem surface, with one ends of the flexible elements Zan with lugs, and opposite gestures 15 to attached to the base plates.

In Fig. 1, a device for pressing the drop support of a shaft shaft is shown, vertical section along the shaft axis; figure 2 - view A on

20 figure 1.

The device includes an end cap 1 with hinges mounted into it 2 fastening lugs 3, power cylinders 4, acting or not lowering

25 support 5. The stops 3 are connected with flexible elements G, missed under the half-collar 7 of the end cap 1 and bred by the other end on the near-shaft surface, where they are rigidly fixed to the base plates 6. The pipes 10 are laid at the bottom of the barrel 9 to accommodate flexible elements b. Installation of the device is carried out in the following sequence. In the pit 9, flexible elements 6 are placed, placing them in advance in pipes 10, the length of which is equal to the width of the sole 7 of the tip 1. The pipes I are placed radially relative to the center of the trunk within the sole 7 of the future tip 1. Some ends of the flexible elements 6 lead out behind the tip 1 on the circumferential surface along the slopes of the pit 9. Then the head 1 is constructed with the garnish 2 rigidly attached thereto. The stop 3 is connected to the hinge 2 by means of a finger 11, while the stop 3 is held in a horizontal position with a help of a sub 12, rigidly dunno with a head 1. The ends of the flexible elements 6, going inside the barrel, are attached to the stops 3 at the same distance from the head, as the point of application of the reactive force of the power cylinders 4. After the backfilling of the pit outside the head 1, a support is placed on the near-barrel surface Plate 8, which are rigidly connected to the free ends of the flexible electrotechtobs E. Then, the preloading of the flexible elements 6 is carried out. The device is ready for the downwelling support. The support 5 is crushed in the course of the installation, a succession of the installation of the next support of the next support and the pressing of this support. After finishing and penetration, the device is removed, the stops 3, plates 8 are removed and the flexible elements 6 are removed. The application of the invention significantly reduces the metal consumption of the device and reduces the consumption of non-turnable metal in comparison with the prototype. The invention of the device for crushing the roof support of a shaft shaft, comprising a head with a base hinged on it. Heads and power cylinders, characterized in that, in order to reduce metal consumption, it is equipped with flexible elements that are missed under the head of the head, and support plates, placed on the side and away from the end cap, with one end of the flexible elements being connected with stoppers, while the opposite ends are attached to the base plates.
