Strong side guard plate is made up of upper guard board and lower backplate, and upper and lower backplate connects, and upper guard board is not less than described coal with the total height of lower backplate
The drop height of wall, roof of coal face height props up at large-mining-height working surface hydraulic pressure of the present utility model with head-room drop
Once add up transition at the reinforcement side guard plate of frame transition frame, therefore avoid conventional fully-mechanized mining working head, tail 15 frame
Gentle transition, decreases coal resources waste, due to without using gentle transition, therefore, it is possible to it is comprehensive to make this utility model reduce
Hydraulic support in mining face head, aircraft tail shelf stings frame risk.
Further, upper guard board of the present utility model is hinged with lower backplate so that lower backplate can swing by upper guard board relatively, has
It is beneficial to avoid hydraulic support to sting frame.
Further, hydraulic cylinder, hydraulic cylinder and liquid are set in the inner side (i.e. near described coal wall side) strengthening side guard plate
Pressure control system connects, and one end of hydraulic cylinder is hinged with lower backplate, the other end and upper guard board or the lower hinge of set cap, liquid
Upper and lower backplate can being played a supportive role of cylinder pressure so that the structure of backplate is more stable, additionally it is possible to the lower backplate of regulation is relative to upper
The swinging of backplate, prevents from pressing support to sting frame.
Further, the height of upper guard board of the present utility model is fixed, and lower backplate is detachable, the height of lower backplate
Height according to coal wall does adaptations so that the height strengthening side guard plate can adapt to differing heights coal wall so that this reality
Higher with the novel suitability.
This utility model improve fully-mechanized mining working coal recovery rate, solve that conventional hydraulic support exists to sting frame hidden
Suffer from, promote substantially in particular for large-mining-height working surface coal recovery rate.

[detailed description of the invention]
Come below in conjunction with the accompanying drawings this utility model is further described.
As shown in Figure 1 to Figure 3, large-mining-height working surface hydraulic support transition frame of the present utility model, including strengthening side guard plate
1, strengthen side guard plate 1 and be arranged on the head transition frame of fully-mechanized mining working and tail transition frame near coal wall side, strengthen side guard plate 1
Including upper guard board 1-1, the upper end of upper guard board 1-1 is fixing with the set cap 2 of transition frame to be connected, and the lower end of upper guard board 1-1 uses
Hinge has the total height drop height not less than described coal wall of lower backplate 1-2, upper guard board 1-1 and lower backplate 1-2, above protects
The height of plate 1-1 is fixed, and lower backplate 1-2 is detachable；The inner side strengthening side guard plate 1 is provided with hydraulic cylinder 3, hydraulic cylinder 3
Being connected with hydraulic control system, one end of hydraulic cylinder 3 is hinged with lower backplate 1-2, and the other end and upper guard board 1-1 be hinged or support top
The lower hinge of beam 2；The inner side of strong side guard plate 1 is additionally provided with reinforcement 4.
This utility model be by former fully-mechanized mining working head, tail transition frame by coal wall side side guard plate intensity enhancing, chi
Very little increasing, once added up roof of coal face height and head-room drop in new type hydraulic bearer transition frame
Cross, it is to avoid conventional fully-mechanized mining working head, tail 15 frame gentle transition, decrease coal resources waste, reduce to combine and adopt work
Make the hydraulic support in face head, aircraft tail shelf and sting frame risk.
The beneficial effects of the utility model are as follows:
Avoiding the potential safety hazard of manual operation, in prior art, coal-winning machine driver is in head, tail gentle transition process
In, it is desirable to coal machine driver constantly lower the height of upper cylinder, the amplitude of downward 2 degree, and it is big that operating process controls difficulty, often goes out
Existing hydraulic support stings frame problem.
Improve the coefficient of mining of coal, decrease the loss of coal resources:
Fully-mechanized mining working transition altitude is Hm, and transition length is Lm, and frame head and tail must transition.Equal at head, tail
Leave triangle transition region, head, tail the area of transition region for being S；
According to triangular form area formula S=1/2 × L × H, head, tail add up to area to be that 2S draws 5-2 coal 2S5-2=1/
2 × 26.5 × 1.1 × 2=29.15 square metre
Draw 5-2 coal 2S2-2=1/2 × 26.5 × 3.3 × 2=87.45 square metre
Coal reserves is P, pushes to adopt a length of D, and it is 1.32 that coal dissipates specific density；
P is drawn according to cubature formula P=D × 2S × 13.25-2=29.15 × 2000 × 1.32=76956 ton
Draw P2-2=87.45 × 2000 × 1.32=230868 ton
After transformation, this wasting of resources can be avoided, can efficient recovery 5-2 coal fully-mechanized mining working resource 76956 tons；Turn one's head
2-2 coal fully-mechanized mining working coal resources 230868 tons.
In prior art, due to difference in height, work surface head, tail need to make gentle transition, and mistake of the present utility model
After crossing frame transformation, work surface need not gentle transition, installs strengthen in head, crossing, tail work surface drop relatively great Liang lane
The transition frame of side guard plate, utilizes reinforcement side guard plate transition frame to carry out transition top board drop.
