RU87210U1 - EXCHANGE EXECUTIVE BODY OF THE MINING SHOCK-CHIPING ACTION - Google Patents

Abstract

The utility model relates to the mining industry, namely, to the mechanical destruction of the rock massif in a selective way during mining and conducting mining operations underground. The executive body of the impact-shearing action consists of a carrier body, which includes a base, a gear case, a gear cover with a sealing device, a bearing assembly, a sleeve in which splines, a key, or another are made, depending on the design of the output shaft of the boom of the executive body. On the axle box of the output shaft of the boom of the executive body, the central sun gear with a removable sealing ring is rigidly installed. The carrier is mounted on the output shaft of the boom of the executive body. The pinion shafts of the satellites are installed in the axleboxes of the bearing units and at one end are engaged with the central sun gear, cutting crowns with cutters are installed on the other end with the help of the sleeve. When the executive body of the combine is turned on, the carrier rotates with the speed of the output shaft n1, the pinion shaft of the satellite gearing with the sun gear drives the cutting crowns with the speed n1 * i (where i is the gear ratio), the speed of the meeting of the cutter with the face is the sum of the speed drove and the speed of the cutting crown, with each cutter of the cutting crown meeting the face once per revolution of the cutting crown, is introduced into the face and out of contact with it, breaking off a piece of rock depending on the feed rate executive body for slaughter.

Description

The utility model relates to the mining industry, namely, to the mechanical destruction of the rock massif in a selective way during mining and conducting mining operations underground.

Known executive body of a tunneling machine, consisting of an arrow, on the output shaft of which an executive body of a crown type is installed. The disadvantage of this executive body is that during operation, the cutters are in contact with the rock mass at a length equal to half the circumference of the executive body, as a result of which they quickly wear out, especially on rocks with a strength above average (f more than 4 according to Prof. Protodyakonov) , also there is a strong dust formation and the exit of a large number of bayonet. When conducting cleaning operations, a screw type working body is widely used, which has the same disadvantages, since the destruction of the rock mass occurs according to the same cutting pattern.

The purpose of the utility model is to increase the efficiency of destruction of a rock mass in a selective way, to reduce dust emission.

The executive body of a shearer of impact-shearing action consists of a central sun gear rigidly mounted on the axle box of the output shaft, the carrier body is worn on the output shaft. The carrier consists of a base on which the axle boxes of the bearing units and the gear housing of the gear carrier with the central sun gear are rigidly located. In the axle boxes of the bearing units, the pinion shaft of the satellite is mounted, which are meshed with the central sun gear. Cutting crowns are installed on the ends of the pinion shaft.

The utility model is illustrated in figure 1, which shows the Executive body shock-shearing action tunneling machine.

The executive body of the impact-shearing action consists of a carrier body, which includes a base 3, a gear housing 4, a gear cover 5 with a sealing device, three axle boxes of a bearing assembly 6, a sleeve 7 in which splines, a key, or another are made, depending on the design the output shaft of the boom of the executive body 2. On the axle box of the output shaft of the boom of the executive body 1, the central sun gear 10 with a removable sealing ring 11 is rigidly mounted. The carrier is mounted on the output shaft of the boom and additionally body 2. The pinion shaft 9 mounted in satellites axlebox bearing units 6 and at one end are in engagement with the central sun gear 10, the other end through a bushing 12 mounted with cutting koronki8 incisors.

When the executive body of the combine is turned on, the carrier rotates with the speed of the output shaft n1, the pinion shaft of the satellite gearing with the sun gear drives the cutting crowns with the speed n1 * i (where i is the gear ratio), the speed of the meeting of the cutter with the face is the sum of the speed drove and the speed of the cutting crown, with each cutter of the cutting crown meeting the face once per revolution of the cutting crown, is introduced into the face and out of contact with it, breaking off a piece of rock depending on the feed rate executive body for slaughter.
