Abstract
The utility model relates to a novel push rod used for pushing a scraper conveyor and pulling a hydraulic bracket on a fully mechanized mining hydraulic bracket in coal mine underground, which comprises a box type rod body and an ear plate, wherein an upper cover plate, a lower cover plate and two side plates of the rod body constitute a box type structure, a stiffener board is arranged in the box, the front part of the lower cover plate is longer than the upper cover plate, the ear plate is arranged above the lower cover plate and at the front part of the upper cover plate, and the front end of the lower cover plate is vertically provided with a stop dog. The novel push rod has the characteristics of reasonable structure, stable performance and the like, and acts reliably.
Description
Technical field
The utility model relates to the novel pusher rod that is used on the comprehensive mining hydraulic bracket under a kind of coal mine pass drag conveyor and draws moving hydraulic support.
Background technology
Hydraulic support is one of visual plant of colliery fully-mechanized mining, and its work plane is the key equipment of exploitation continuously, for mechanical mining provides the necessary security working space.Along with the extensive use of hydraulic support in China mining area, the requirement that the reliability of hydraulic support and life-span have been proposed higher more science.And pusher rod is as an important component part of hydraulic support, and its service behaviour directly has influence on the operating efficiency and the reliability of hydraulic support.Existing hydraulic support pusher rod is welding box-shaped structure, and it is low that jack is passed the position, is not easy to the installation of jack, in the passing process, have from the horizontal by the component of an angle, and in the passing process, the frictional force that pusher rod is subjected to is bigger, has influenced the service behaviour of beetle haulage system.
Summary of the invention
The utility model provides a kind of rational in infrastructure in order to overcome above-mentioned defective, reliable in action, the novel pusher rod of stable performance.
The technical solution adopted in the utility model is: a kind of novel pusher rod, comprise the box-type body of rod and otic placode, described body of rod upper cover plate, lower cover and two side plates are formed box typed structure, be provided with the reinforcement gusset at box house, upper cover plate is longer than in the front portion of described lower cover, above lower cover, the front portion of upper cover plate is provided with otic placode, at the front end of lower cover block is set vertically.
The otic placode that the utility model will connect jack is set to the front portion of the pusher rod body of rod, so just makes to pass the some reach, and promptly the stress point position uprises, and has only horizontal component in the passing process, and the resistance of reducing friction improves effect, makes that to pass action more reliable; After the reach of jack link position, the installing space of jack on support strengthened, be convenient to I﹠M.
Description of drawings
Fig. 1 is a schematic diagram of the present utility model.
Fig. 2 is the vertical view of Fig. 1.
The specific embodiment
Now in conjunction with the accompanying drawings the utility model is further described, Fig. 1 and Fig. 2 have represented a kind of embodiment of the present utility model, mainly comprise the box-type body of rod and otic placode 3, described body of rod upper cover plate 1, lower cover 2 and two side plates 4 are formed box typed structure, be provided with reinforcement gusset 5 at box house, upper cover plate 1 is longer than in the front portion of described lower cover 2, above lower cover 2, the front portion of upper cover plate 1 is provided with otic placode 3, front end at lower cover 2 vertically is provided with block 6, and block 6 is used for playing the effect of guiding moving frame and pushing and sliding process.
The utility model is anterior to be connected with jack by otic placode 3, and the rear portion is connected with drag conveyor, thereby realizes moving the function of slipping and trying to stop people from fighting each other.Because the otic placode 3 that the utility model will connect jack is set to the front portion of the pusher rod body of rod, so just make and pass the some reach, promptly the stress point position uprises, and has only horizontal component in the passing process, the resistance of reducing friction improves effect, make pass move more reliable.Simultaneously, after the reach of jack link position, the installing space of jack on support strengthened, be convenient to I﹠M.
The utlity model has characteristics such as rational in infrastructure, reliable in action, stable performance.
