Description

The invention relates to mining and can be used for mechanization of blasting when loading wells with loose and emulsion explosives.

A device is known for loading holes and boreholes with loose explosives (AS No. 841439, published May 27, 2004), including a charger, a charging hose, a feeding mechanism for a charging hose into a hole and a device for controlling the distance from the end of the charging hose to the front of the generated charge connected by means of a command device with a charging hose feed mechanism, moreover, the control device is made in the form of an ultrasonic locator containing an emitter - receiver - ultrasound transducer mounted on the end of the charging hose azvukovyh signals, an ultrasonic generator power with the device, the set interval of ultrasonic signals, and a circulator alternately switching emitter - receiver - transmitter generator and amplifier sequencer.

The disadvantage of this invention is the design complexity, as well as a low pressure force when feeding the hose, limiting the length of the feed hose.

A device is known for supplying a charging hose to a well (a.s. of the Russian Federation No. 1558137, publ. 20.01.1996), including a pair of feed rollers on the shafts, a device for rotating the rollers with a main for supplying compressed air to it, a device for rotating the rollers is made in the form pneumatic chambers, evenly spaced around the circumference of the rollers, and pneumatic distributors for the sequential supply of compressed air to groups of pneumatic chambers, located opposite to each other on the parts of the circumferences of the rollers at the beginning of the quarters of these circles, starting from the diametrical line passing through the axes of both rollers, and the discharge of compressed air from them after leaving these sections.

The disadvantage of this invention is the design complexity, low speed, as well as low pressure force when applying the hose, limiting the length of the feed hose.

A device is known for supplying a charging hose to a well (a.s. USSR No. 335355, 1982), comprising a cylinder with a piston, a control member and pneumatic grippers.

The disadvantage of this device is the deformation of the charging hose in the air grips, the use of an additional spacer device for securing the feeder in the mine, a lot of weight, the inability to charge in the ascending wells with a height of more than 20 m.

A device is known for supplying a charging hose to a well (Drukovany M.F. et al. Mechanization of blasting operations. - M .: Nedra, 1984, p. 194, Fig. 97.), including a spacer column, a gripping unit and a drive mechanism.

The disadvantage of this is the deformation of the charging hose in the squeezing rollers of the gripping unit, the impossibility of uniformly lowering the hose during charging of explosive wells, the installation of a spacer column in the dimensions of the mine, and the inability to charge rising wells more than 20 m deep.

A device for feeding a charging hose into a well, adopted as a prototype (patent RU No. 2091580, publ. 09/27/1997). The inventive device for supplying a charging hose contains a plug with a slot for passing through it a cable (for example, a nylon cord), the ends of which are connected to the charging hose and drum. The latter is mounted on an axis in the cutout of the end part from one end of the spacer pipe located at the wellhead at the second end. An air motor with a gearbox and an air supply hose on which the crane is mounted is connected to the cheek of the shaped cut-out of the spacer pipe. A spacer pipe with a cable tensioning mechanism attached to it is installed at the wellhead by pulling the rods with the lever of the shaped wedge in the pipe cut.

The disadvantage of this invention is the low pressure force when feeding the hose, limiting the length of the feed hose.

The technical result of the claimed invention is to increase the pressure head when feeding a charging hose and the possibility of feeding a longer hose.

The technical result is achieved by the fact that in the device for supplying the charging hose to the well, comprising a housing with fasteners and hose guides, a gripping unit and a hydraulic drive mechanism mounted on a pipe-shaped spacer, according to the invention, the gripping unit is made in the form of two symmetrically arranged endless chains with pads fixed on them, equipped with semicircular recesses and serrated notches, the drive mechanism is made in the form of pairs of drive and driven sprockets equipped with a tension bubbled bars, and the expander member is a regulated clamping plugs with supporting strips and elastic members installed within a space formed by an endless chain drive and driven sprockets symmetrically with respect to the tubular spacer element.

The technical result is also achieved by the fact that the carrier frame of the device is mounted on the frame of the carrier device using quick-release latches.

A device for supplying a charging hose to a well comprises a housing 1 of a device for supplying a charging hose to a well, made collapsible, for example, on a bolted connection. The housing 1 is equipped with fastenings 2 of the device for supplying the charging hose into the well to the supporting frame 4, connected, for example, by quick-release clamps. In the lower part, the housing 1 is provided with a protective casing 3 of the housing 1. The device comprises a supporting frame 4, which is rigidly fixed to the carrier device (for example, an underground mixing and charging machine), for example, using a welded or bolted connection. On the sides of the inlet and outlet of the charging hose from the housing 1, guides 5 of the charging hose are installed, for example, in the form of pipe segments with stiffeners with an inner diameter larger than the diameter of the charging hose. In the upper part of the housing 1 are hydraulic actuators 6, connected by a shaft to the drive sprockets 7. The drive sprockets 7 of the drive mechanism are mounted to rotate in the housing 1. Also, driven sprockets 8 of the drive mechanism are mounted to rotate inside the housing 1. The endless chains 9 are installed with the possibility of movement on the leading 7 and driven 8 sprockets. On the outer side of the endless chains 9, pads 10 are rigidly fixed with semicircular recesses and serrated notches in each (conditionally not shown). Inside the housing 1, tension rods 11 for driven sprockets 8, support bars 12 of adjustable clamping forks 14 are installed. In the inner space formed by endless chains 9, elastic elements 13 are installed to regulate the thrust in adjustable clamping forks 14. For serviceability, a viewing cover is provided in the housing 1 15, as well as slots 16 for access to the elastic elements 13.

A device for supplying a charging hose to the well operates as follows. The charging hose is pushed into the capture unit, made in the form of two symmetrically arranged endless chains 9 with pads 10 fixed on them with semicircular recesses and serrated notches in each. Due to the presence of semicircular recesses and serrated notches on them on the pads 10, the maximum contact surface of the pads 10 with the outer surface of the charging hose without its deformation is provided. The movement of the charging hose is carried out by switching on the opposite side of the drive mechanism in the form of a hydraulic actuator 6, which drives a pair of leading 7 and driven 8 sprockets. Hydraulic energy is obtained from an external source, for example, from a mixing and charging machine. By supplying the driven sprockets 8 with tension rods 11, the required tension of the endless chain 9 with no slippage is guaranteed to ensure a high feed force. The spacer element is made in the form of adjustable clamping forks 14, mounted symmetrically with respect to the tube-shaped spacer between the leading 7 and driven 8 sprockets, inside the space of endless chains 9. Adjustable clamping forks 14 with support plates 12 and elastic elements 13 allow you to adjust the pressure force of the pads 10 to the surface charging hose, which makes it possible to give a greater pressure force. To carry out repairs and adjust the mechanism, you can remove the inspection cover 15 or use lockable slots 16 to access the elastic elements 13.

The use of a device for supplying a charging hose to a well provides the following advantages:

- increase pressure head when feeding the charging hose;

- the possibility of feeding a hose of a greater length;

- improving the reliability of the nozzle design;

- simplification of the design of the device.
