Description

(5) DEVICE FOR FASTENING OF A CLEANING MACHINE.

one

The invention relates to mining, more specifically to mechanized fortifications for cleansing faces.

A device for mounting outcrops is known, including the overlapping of a shaft mechanized support section, pressure plates with brackets connected by a hinge, and power hydraulic cylinders mounted between the brackets adjacent to each other of the plates C1.

A disadvantage of this device is the complexity of the design and the lack of visual observation of the state of the slaughter, which reduces safe working conditions.

The closest to the proposed technical essence and the achieved result is a device for fastening the bottom of the excavation workout, including a visor connected pivotally with the overlapping of the support section, pressure plate attached to the shield

telescopic traverses with clamps and hydraulic jack C21.

A disadvantage of the known device is the lack of adaptability of the pressure plate to unevenness of the bottom.

The purpose of the invention is to improve the adaptability of the pressure plate to unevenness of the bottom.

This goal is achieved by

10 that the pressure plate is made in the form of a lattice of resilient transverse plates with grooves, elastic vertical elements installed in the grooves, and an elastic concave in the side of the bottom, located vertically in the middle of the shield, the pressure plate hinged to the visor, and the telescopic the traverses are hingedly attached to the overlap of the lining section with the possibility of longitudinal movement at the point of attachment,

FIG. Figure 1 shows the installation of the proposed device on a fur lined support section 39, side view; in fig. 2 is a view A of FIG. 1. The device for securing the bottom consists of a clamping shield 1, made in the form of a lattice of elastic vertical elements 2, inserted into the grooves 3 of elastic transverse plates 4 fixed with bolts 5- In the middle of the shield 1 the insert 6 is inserted concavely. The shield 1 is hinged to the top of the visor 7 with a sliding top 8 and is connected to the telescopic yoke 9 having an IQ lock and a longitudinal groove 11. The telescopic yoke 9 is connected to the hydrojack 12. The device operates as follows. When supplying the working fluid under pressure to the rod end of the hydraulic cylinder 12, the rod of the latter moves in and with the help of the crosspiece 9 and the groove 11 removes the shield 1 from the bottom and folds under the visor 7. After the excavation machine passes, the working liquid is fed into the piston cavity of the hydraulic cylinder 12, the rod of which extends and moving the yoke 9 with the groove 11 towards the bottom side, simultaneously pushing the top toward 8 with the visor 7, while the shield 1 is pressed against the bottom. The telescopic yoke 9 with the latch 10 and the longitudinal groove 11 allows you to adjust the shield pressing without sliding the top 8, sliding the section of the lining, and pushing the top to 8 with the visor 7 without using the pressure plate 1 and depending on the specific nature for these conditions and the places of occurrence of the extraction of coal or bare) {eni roofing. 14 This embodiment of the device for fixing outcrops at the bottom improves the operability of the mechanized roof in difficult geological conditions, reduces the amount of manual work on stripping the lava, increases the productivity of the cleaning complex and increases the safety of work. Claim device The device for fixing the bottom of the clearing generation, comprising a visor connected hingedly to the overlapping of the support section, a pressure plate, hinged to the shield telescopic traverses with clamps and a hydraulic jack, characterized in that, in order to improve the adaptability of the pressure shield to unevenness, the clamp is attached to an unevenness, the shield is made in the form of a lattice of elastic transverse plates with grooves, elastic vertical elements installed in the grooves, and an elastic concave in the side of the bottom plate located vertic in the middle of the shield, the clamping shield is hinged to the visor, and the telescopic traverses are hingedly attached to the overlap of the support section with the possibility of longitudinal movement at the attachment point.
