Abstract
The utility model relates to the technical field of hydraulic brackets for the underground mechanized mining of a coal mine, in particular to a telescopic beam of a hydraulic bracket. The telescopic beam of the hydraulic bracket comprises at least three steel plates, bent plates and ear plates, wherein the ear plates in pairs are vertically arranged below the front ends of the steel plates; two sets of ear plates are arranged below each steel plate; connecting holes are arranged on the ear plates; the bent plates are right angle-shaped; arc transitions are arranged at the corners of the bent plates; and the bent plates are connected above the front ends of the steel plates and at the front parts of the ear plates. The telescopic beam has the characteristics that the telesopic beam has a simple structure and small thickness and is convenient to operate and not easy to deform, etc.
Description
Technical field
The utility model relates to comprehensive mining hydraulic bracket technical field under a kind of coal mine, specifically a kind of extensible canopy of hydraulic support.
Background technology
Extensible canopy at the front end of hydraulic support back timber or front-axle beam, is used to prevent working face wall top top coal inbreak as a structure member of hydraulic support.During off working state, extensible canopy is positioned at the inside of back timber or front-axle beam.During work, extensible canopy stretches to rib under the effect of its jack, plays the immediate support effect in the coal mining process, is an important non-body junction member.Existing hydraulic support extensible canopy is welding box-shaped structure, and appearance and size is big, and it is big to take installing space, and the thickness of back timber is generally bigger, easy deformation in use, not only blocked portion but also maintenance difficult easily after the distortion.
Summary of the invention
In order to overcome above-mentioned defective, it is a kind of simple in structure, easy to operate that the utility model provides, and thickness is little, on-deformable hydraulic support extensible canopy.
The technical solution adopted in the utility model is: a kind of hydraulic support extensible canopy, described extensible canopy is a plank frame, comprise steel plate, bent plate and otic placode, two of described otic placodes are one group of below that is vertically set on the steel plate front end, and described steel plate is at least three, and every block plate below is provided with two groups of otic placodes, otic placode is provided with connecting hole, described bent plate be 90 the degree rectangular-shaped, corner is an arc transition, this bent plate is connected the top of steel plate front end and the front portion of otic placode.
The utility model extensible canopy is set to plank frame, and thickness is little, and is in light weight, not yielding in the use, and after the integral thickness of extensible canopy reduced, back timber thickness just can and then reduce, and minimum mining height can be reduced; It is for the ease of being connected with jack, bent plate being set in order to increase the intensity of extensible canopy, the impaired distortion of protection extensible canopy that otic placode is set.
Description of drawings
Fig. 1 is a schematic diagram of the present utility model.
The specific embodiment
Now in conjunction with the accompanying drawings the utility model is further described, Fig. 1 is a schematic diagram of the present utility model, mainly comprise steel plate 1, bent plate 2 and otic placode 3,3 two of described otic placodes are one group of below that is vertically set on steel plate 1 front end, described steel plate 1 is at least three, and present embodiment light plate 1 is three, and every block plate 1 below is provided with two groups of otic placodes 3, otic placode 3 is provided with connecting hole, and the effect of otic placode 3 is to be connected with jack for convenience.Described bent plate 2 is that 90 degree are rectangular-shaped, and the corner of bent plate 2 is the arc transition shape, and this bent plate 2 is connected the top of steel plate 1 front end and the front portion of otic placode 3, bent plate 2 can shoulder guard 1 and otic placode 3 impaired, can also improve the intensity of steel plate 1.
When the utility model used, front end was connected with jack by otic placode 3, and using method is identical with traditional extensible canopy.
The utlity model has simple in structure, easy to operate, characteristics such as thickness is little, and is not yielding.
