Abstract

The utility model relates to a colliery is combined in pit and is adopted working face crossheading scraper blade elevating conveyor field, specifically is a tight chain's of flexible tail crossheading scraper blade elevating conveyor, including simple and easy aircraft nose transmission portion, middle part section, flexible tail. The traditional crossheading scraper elevating conveyor is tightly linked by a telescopic machine head, the telescopic machine head consists of a machine head frame, a rear groove body and a transmission device, and the telescopic machine head is complex in structure, difficult to machine and high in cost. The telescopic machine head is positioned at the bridge section, and under the action of the unbalanced weight of the transmission device, the telescopic lap joint part of the machine head frame and the rear groove body is subjected to unbalanced torsion, so that the clamping resistance is large during telescopic operation, and even the clamping phenomenon is caused; and the lapping part of the headstock middle plate and the rear groove body middle plate is uneven, and the scraping and clamping damage of the scraper can be caused in serious conditions. The utility model discloses the fine above-mentioned problem of having avoided of crossheading scraper blade elevating conveyor of the tight chain of flexible tail, through the tight chain of flexible tail that is located the section of falling to the ground, the operation is more convenient safe and reliable, simple and easy aircraft nose transmission reduction in production cost moreover.

Description

Crossheading scraper elevating conveyor of tail chain tightening of telescopic conveyor

Technical Field

The utility model relates to a colliery is combined in pit and is adopted working face crossheading scraper blade elevating conveyor field, specifically is a tight chain's of flexible tail crossheading scraper blade elevating conveyor.

Background

In the underground fully mechanized coal mining face of a coal mine, a crossheading scraper elevating conveyor is fixed on a belt self-moving tail in an overlapping mode and takes charge of the transferring task of coal. The traditional crossheading scraper elevating conveyor is tightly linked by a telescopic machine head, the telescopic machine head consists of a machine head frame, a rear groove body and a transmission device, and the machine head is complex in structure, difficult to machine and high in cost. The telescopic machine head is lapped on the belt self-moving machine tail, under the action of the weight bias of the transmission device, the machine head frame and the telescopic lapping part of the rear groove body are biased to twist, so that the clamping resistance is large during telescopic operation, even the phenomenon of clamping is dead, and the machine head cannot be pulled back when the cylinder is retracted; meanwhile, the lapping part of the headstock middle plate and the rear groove body middle plate is uneven, and the scraping and clamping damage of the scraper can be caused in serious cases. These are the urgent problems to be solved for the construction of safe high-yield high-efficiency mines.

Disclosure of Invention

In view of this, the utility model aims at providing a crossheading scraper blade elevating conveyor of tight chain of flexible tail, including simple and easy aircraft nose drive division, middle part section, flexible tail. The simple machine head cancels a telescopic structure used in the prior art, is of an integral welding structure, and has compact and simple structure and light weight. The flexible tail is located the section of falling to the ground, through being located the flexible tight chain of adjustable shelf of tail frame inside, the more convenient safe and reliable of operation.

The utility model adopts the technical proposal that: a crossheading scraper elevating conveyor for tensioning a chain at the tail of a telescopic conveyor comprises a simple head transmission part 1, a middle section 2 and a telescopic conveyor tail 3; the simple machine head transmission part 1 consists of a simple machine head frame 11 and a transmission device 12; the simple headstock 11 is of an integral welding structure, a fixing pin B is welded on a bottom plate, and the simple headstock is fixedly connected with a belt self-moving tail A through the fixing pin B.

Further, the telescopic tail 3 is composed of a tail frame 31, an oil cylinder 32 and a movable frame 33; the movable frame 33 is built in the tail frame 31, and one end of the oil cylinder 32 is connected with the tail frame 31, and the other end is connected with the movable frame 33.

The utility model relates to a crossheading scraper blade elevating conveyor of tight chain of flexible tail, design benefit. The simple machine head has the advantages of compact and simple structure, light weight and low cost. Through the flexible tight chain of adjustable shelf that is located tail frame inside, the simple operation safe and reliable more. The design can effectively reduce the failure rate of equipment, prolong the service life of the equipment, reduce the labor load of workers and improve the mining and transportation efficiency of a mine.

The technical solution of the present invention will be described in detail with reference to the accompanying drawings and the detailed description.

Description of the drawings:

FIG. 1 is a schematic structural view of a crossheading scraper elevating conveyor of the tail chain tensioner of the telescopic conveyor of the present invention;

FIG. 2 is a schematic view of the simple head transmission part of the present invention;

FIG. 3 is a schematic structural view of a conventional elevating conveyor telescopic head;

FIG. 4 is a schematic view of the structure of the tail of the telescopic machine of the present invention;

in the figure: 1 simple head transmission part, 11 simple head frame, 12 transmission device, 2 middle section, 3 telescopic tail, 31 tail frame, 32 oil cylinder and 33 movable frame

The specific implementation mode is as follows:

the following detailed description of the embodiments of the present invention is made with reference to the accompanying drawings:

as shown in fig. 1, 2 and 3, the crossheading scraper elevating conveyor of the tail chain tightening of the telescopic conveyor of the present invention comprises a simple head transmission part 1, a middle section 2 and a telescopic conveyor tail 3; the simple machine head transmission part 1 consists of a simple machine head frame 11 and a transmission device 12; the simple headstock 11 cancels the traditional telescopic structure, is an integral welding structure, can not stretch out and draw back, and the bottom plate welding has fixed pin B, through fixed pin B and belt from moving tail A fixed hookup.

In addition, the telescopic tail 3 consists of a tail frame 31, an oil cylinder 32 and a movable frame 33; the movable frame 33 is built in the tail frame 31, and one end of the oil cylinder 32 is connected with the tail frame 31, and the other end is connected with the movable frame 33. The stretching of the movable frame 33 in the tail frame 31 can be controlled by the stretching of the oil cylinder 32, and the tightness of the scraper chain can be further controlled. The extension and contraction of the movable frame 33 in the tail frame 31 does not affect the matching relationship with the outside.
