Abstract
The utility model relates to an improved structure of a track walking type hydraulic support for borehole room and pillar type mining and pillar mining working surface in the coal industry for solving the problems that the track walking type hydraulic support eliminates barriers such as caving cinderpelt, the people is saved and self-rescued by creeping when the support is pressed and the support is overhauled conveniently. A coal plough plate and a rear support are respectively articulated with the front and rear part of a hydraulic support base, and the coal plough plate, the hydraulic support bas and a hydraulic jack are mutually articulated, and the rear support, the hydraulic support base and the hydraulic jack are mutually articulated. If the barriers such as caving cinderpelt exist in front of the track walking type hydraulic support, the coal plough plate can be extended for eliminating the barrier; an ear plate is arranged at the front end of the coal plough plate for large-area caving, when the track walking type hydraulic support is pressed so as not to escape, the support can escape by virtue of external force by the ear plate; meanwhile, the coal plough plate and the rear support act on at the same time for leading the track walking type hydraulic support to be wholly lifted for conveniently leading the people to be self-rescued by creeping through the support or the support to be overhauled.
Description
Technical field

Background technology
At present, known hydraulic support is made up of back timber, caving shield, column, front-rear linkage, base and thrust gear etc., is the mechanization support apparatus that is used for the longwell fully-mechanized mining.The research of caterpillar track travelling hydraulic support and the concrete existing pertinent literature report both at home and abroad of using, but introduce the application of caterpillar track travelling hydraulic support in actual coal work mostly in the pertinent literature both at home and abroad, and need are removed support the place ahead inbreak bastard coal in actual coal work, directly top large tracts of land inbreak, support is pressed in the time of can not escaping voluntarily, need to escape by external force, base is absorbed in base plate and need climbs nest and save oneself, when changing creeper tread and overhaul of the equipments, need that the hydraulic support complete machine such as is propped at problem and solve very difficult.
The utility model content
The purpose of this utility model is to provide a kind of improvement structure of caterpillar track travelling hydraulic support, being used to solve caterpillar track travelling hydraulic support removes obstacles such as emitting the coal breakage skin, is rescued, climbs that nest is saved oneself and problem such as easy access when being pressed, can realize that caterpillar track travelling hydraulic support removes roadblock, escape, climb that nest is saved oneself and convenient maintenance function by part external force.
The technical solution of the utility model is:
A kind of improvement structure of caterpillar track travelling hydraulic support has hydraulic support foundation, and the front and back of hydraulic support foundation are hinged with coal-ploughing board respectively, the back is supported.
The improvement structure of described caterpillar track travelling hydraulic support, it is characterized in that: be respectively equipped with connection otic placode I before and after the hydraulic support foundation, connect otic placode II, hydraulic support foundation is hinged by connecting otic placode I and coal-ploughing board, and hydraulic support foundation supports hinged by connecting otic placode II with the back.
The improvement structure of described caterpillar track travelling hydraulic support, it is characterized in that: hydraulic jack I is housed on the coal-ploughing board, the back is supported hydraulic jack II is housed, and with to be connected otic placode I hinged, hydraulic jack II is passed through in the back support and to be connected otic placode II hinged by hydraulic jack I for coal-ploughing board.
The improvement structure of described caterpillar track travelling hydraulic support is characterized in that: coal-ploughing board is provided with traction ear seat.
The beneficial effects of the utility model are:

The specific embodiment
As shown in Figure 1, the structural representation that is connected with the caterpillar track travelling hydraulic support base is supported in the utility model coal-ploughing board and back.Caterpillar track travelling hydraulic support mainly comprises: hydraulic jack I1, traction ear seat 2, coal-ploughing board 3, hydraulic support foundation 4, back support 5 and hydraulic jack II6, connection otic placode I7, connection otic placode II8, coal-ploughing board 3, back support 5 are articulated in the front and back of hydraulic support foundation 4 respectively, and concrete structure is as follows:
The utility model is realized the support of coal-ploughing board 3 and back support 5 and is lifted action by stretching of HYDRAULIC CONTROL SYSTEM hydraulic jack (hydraulic jack I1, hydraulic jack II6).
As shown in Figure 2, caterpillar track travelling hydraulic support is climbed nest and is saved oneself and overhaul schematic diagram.Need climb nest and save oneself and maybe need to change creeper tread and when overhauling when caterpillar track travelling hydraulic support is absorbed in base plate, can make coal-ploughing board 3, back support 5 by hydraulic jack I1, hydraulic jack II6 effect stretches out simultaneously, caterpillar track travelling hydraulic support integral body is lifted, so that carry out inspection operation.
Schematic diagram when as shown in Figure 3, caterpillar track travelling hydraulic support is rescued by pressure.Directly top large tracts of land inbreak, caterpillar track travelling hydraulic support is pressed in the time of can not escaping voluntarily, can escape by the traction ear seat 2 on the external force traction coal-ploughing board.
As shown in Figure 4, the coal-ploughing board schematic diagram of removing obstacles.When obstacle such as the coal breakage of emitting skin is arranged on the caterpillar track travelling hydraulic support travel direction, adjust coal-ploughing board 3, ensure moving ahead smoothly of caterpillar track travelling hydraulic support to suitable attitude rid.
