Abstract
The utility model relates to a novel front canopy guiding block of a hydraulic support, which overcomes the defects that the existing hydraulic support guiding block is easy to damage and can't be repeatedly used, thereby causing a huge waste. The novel guiding block of the hydraulic support front canopy includes a guiding block main body, and a bolt hole is arranged on the guiding main body. The novel front canopy guiding block of the hydraulic support is characterized in that a groove is formed in the guiding block main body, and the bolt hole is arranged in the groove. The novel guiding block of the hydraulic support front canopy reduces the maintenance workload of the hydraulic support, dispenses with the workload required for replacing the front canopy on the coal mining working surface, improves the safety performance, improves the economic benefits, reduces the safety hazard of the replacement of the front canopy, and is applicable to all sorts of hydraulic supports.
Description
Technical field
The utility model relates to a kind of new type hydraulic bearer forestope guide pad.
Background technology
After work plane uses ZDB2400-06-12A type hydraulic support for low coal seam---spillplate---ramp plate to unite the technology of coalingging in enormous quantities since 2006; Through use at several work planes; In use find; The forestope of hydraulic support is uneven owing to top board, the forestope unbalance stress.Blow out on the coal-face and collapse, the flexible speed of forestope is inconsistent, and it is disconnected to cause the set bolt of forestope guide pad to be sheared, or bolt to expose screw thread impaired, cause set bolt to lay down.Causing part to damage forestope can't repair, or slices off the set bolt of forestope guide pad with gas cutting, is destructive maintenance, causes the guide pad of forestope to reuse, and causes significant wastage.
The utility model content
The technical problem that the utility model will solve is the above-mentioned defective that how to overcome prior art, and a kind of new type hydraulic bearer forestope guide pad is provided.
For solving the problems of the technologies described above, this new type hydraulic bearer forestope guide pad comprises the guide pad body, and this guide pad body is provided with bolt hole, it is characterized in that: this guide pad body has groove, and said bolt hole just is arranged in this groove.So design, during use, bolt is in the protection of groove, and is unsuitable impaired.
As optimization, said groove is a square groove, and its width equals the inscribed circle diameter of adapted nut, the stud bolt hole degree of depth that its degree of depth is run through greater than the length and the adapted screw rod of adapted screw rod poor.After the adapted screw rod was installed, screw rod did not expose.So design, disconnected even the one side bolt is sheared, only need gently a up top screw rod, can easily take off guide pad.Guide pad can continue to use through behind the process and remould like this; On the other hand, nut is stuck in the groove, matching board hand in addition, and easy accessibility, screw rod does not expose on the other hand, is difficult for impairedly, is convenient to demounting bolt.
This new type hydraulic bearer forestope guide pad has reduced the support maintenance load, has solved the workload of changing forestope on the coal-face, has improved security performance, has improved economic benefit.Reduce the potential safety hazard of changing forestope, be applicable to various hydraulic supports.
Description of drawings
Below in conjunction with accompanying drawing this new type hydraulic bearer forestope guide pad is described further:
Fig. 1 is the plan structure sketch map of this new type hydraulic bearer forestope guide pad;
Fig. 2 is that the A-A of this new type hydraulic bearer forestope guide pad is to generalized section.
Dotted line is represented adapted bolt, support among the figure, among the figure: 1 for the guide pad body, 2 for bolt hole, 3 for groove, a be that the width of square groove, the degree of depth that s is square groove, the inscribed circle diameter that d is the adapted nut, length, the g that L is the adapted screw rod are the stud bolt hole degree of depth that the adapted screw rod is run through.
The specific embodiment
Embodiment one: like Fig. 1, shown in 2, this new type hydraulic bearer forestope guide pad comprises guide pad body 1, and this guide pad body 1 is provided with bolt hole 2, it is characterized in that: this guide pad body has groove 3, and said bolt hole 2 just is arranged in this groove 3.
Said groove 3 is a square groove, and its width a equals the inscribed circle diameter d of adapted nut, and the stud bolt hole degree of depth g's that its degree of depth s is run through greater than the length L and the adapted screw rod of adapted screw rod is poor.Be a=d, s＞L-g.
Claims (2)
1. a new type hydraulic bearer forestope guide pad comprises the guide pad body, and this guide pad body is provided with bolt hole, it is characterized in that: this guide pad body has groove, and said bolt hole just is arranged in this groove.
2. new type hydraulic bearer forestope guide pad as claimed in claim 1; It is characterized in that: said groove is a square groove; Its width equals the inscribed circle diameter of adapted nut, the stud bolt hole degree of depth that its degree of depth is run through greater than the length and the adapted screw rod of adapted screw rod poor.
