Description
Technical field
The present invention relates to mining supports apparatus field, specially a kind of supporting is simple, efficiently extension forestope.
Background technology
At present, forestope is particularly important in mining industry operation process, and its stability is for subsequent production and constructor
Member's safety has large effect, past, and staff adds the strings such as sleeper in fact to consolidate forestope, complex operation by suspension ring
And waste time and energy, and in operation, easily there is safety problem.
The content of the invention
In order to solve the above technical problems, the present invention provides a kind of extension forestope.
The present invention is achieved through the following technical solutions：A kind of extension forestope, including pillar；The pillar upper end is fixed
There is horizontally disposed sleeve；Support beam is set with the sleeve；The front end of the support beam is provided with slide opening；It is sliding in the slide opening
It is dynamic that slide bar is installed；The front end of the slide bar is hinged with connecting rod；The connecting rod front end is provided with hinge hole, the support beam rear end
It is provided with hinge hole；In use, the support beam rear end in an extension forestope and the connecting rod in another extension forestope
Front end is hinged.
It is further：The pillar is hydraulic prop.
Two screw holes are provided with the sleeve, screw hole is arranged on the sidepiece of sleeve；Telescopic screw is provided with hole
Trip bolt I.
The front end of the support beam is provided with two screw holes, and screw hole is arranged on the sidepiece of support beam；Support beam screw
Trip bolt II is installed on hole.
The groove of elongated connection slide opening is provided with the downside of the front end of the support beam；The slide bar is fixed with sliding pin, sliding pin
In groove.
Compared with prior art, the beneficial effects of the invention are as follows：Extension forestope can be connected with each other, and not influenceed each other
Between supporting, and simple to operate, supporting is quick, and security and stability are greatly improved, and improves production efficiency, real
Now keep the safety in production.

Embodiment
It is the specific embodiment of the present invention below, in conjunction with accompanying drawing, the present invention will be further described.
As depicted in figs. 1 and 2, a kind of extension forestope, the upper end of pillar 1 are fixed with horizontally disposed sleeve 2；Sleeve 2
In be set with support beam 3；Two screw holes are provided with sleeve 2, screw hole is arranged on the sidepiece of sleeve；On the screw hole of sleeve 2
The 2-1 of trip bolt I is installed, the 2-1 of trip bolt I is used for sleeve 2 and positioning.
The front end of support beam 3 is provided with slide opening 8；Slide bar 4 is slidably fitted with slide opening 8；The front end of support beam 3 is provided with two
Screw hole, screw hole are arranged on the sidepiece of support beam 3；The 3-1 of trip bolt II, trip bolt are installed on the screw hole of support beam 3
II 3-1 is used to position slide bar 4 and support beam 3.The groove 7 of elongated connection slide opening 8 is provided with the downside of the front end of support beam 3；It is sliding
Bar 4 is fixed with sliding pin 6, and sliding pin 6 is located in groove 7, and sliding pin 6 one can prevent slide bar 4 from sliding, and two can place slide bar 4
Rotate.
The front end of slide bar 4 is hinged with connecting rod 5；The front end of connecting rod 5 is provided with hinge hole, and the rear end of support beam 3 is also provided with hinge hole；Such as
Fig. 2, in use, the rear end of support beam 3 in an extension forestope is cut with scissors with the front end of connecting rod 5 in another extension forestope
Connect, be easy to multiple extension forestope quick supportings.
