Description
Technical field
This utility model relates to a kind of lightweight down-hole support frame, belongs to Underground Mine hydraulic support technical field.
Background technology
Hydraulic prop, as down-hole support apparatus, is widely used in tunnel and the stope infall of underground mining, provides safe space for fully-mechanized mining equipment and pedestrian, it is achieved mechanical coal mining.
Although hydraulic prop can play the effect of down-hole supporting, and use hydraulic prop carries out supporting and facilitates later maintenance and maintenance cost low, but, restriction due to himself structure, there is the biggest restriction in the setting load and the supporting intensity that cause hydraulic prop, it is impossible to enough meets the general working face of operating mode in the face of setting load and the demand of supporting intensity.Meanwhile, hydraulic prop in use, needs to be arranged side by side simultaneously and multiple roof is carried out supporting, so causes the work that early stage is installed and the later stage removes the most loaded down with trivial details.
In the fully-mechanized mining working that some operating modes are general, if using hydraulic prop to carry out supporting to need to face the problems referred to above, it is unfavorable for actual production, therefore, prior art is badly in need of to provide a kind of down-hole support frame that can adapt to the general fully-mechanized mining working of operating mode, the lightest and maintenance cost is low, disclosure satisfy that again down-hole supporting intensity requirement.
Utility model content
The purpose of this utility model is to provide a kind of down-hole support frame that disclosure satisfy that fully-mechanized mining working that operating mode is general.
For achieving the above object, the technical scheme of this utility model lightweight down-hole support frame is:
A kind of lightweight down-hole support frame, including base, supported by support post and quadric chain on base and have back timber, support post is provided with two groups along base time interval, and described quadric chain is between two groups of support posts, and the two ends up and down of support post are hinged with back timber, base respectively, quadric chain includes connecting rod, upper small end is hinged with back timber, and upper connecting rod is hinged with front rod, back link, and the lower end of front and rear connecting rods is hinged with base.
Described base is provided with the advancing jack that telescopic direction extends to front-rear direction, and one end of advancing jack is hinged with base, and the other end is hinged with the push rod that axis extends along the longitudinal direction.
Pan frontward end is arranged over for base upwards jack-up is lifted end jack in push rod, lifts that end jack is hinged with base and hinge axes extends in left-right direction.
Pan frontward end is installed with otic placode, described in lift end jack by otic placode hinged with base.
Often group support post all includes two columns, and two columns are between left and right every setting, and two groups of support posts form corner and support.
The beneficial effects of the utility model are: this utility model time interval between back timber and base is provided with two groups of support posts, before quadric chain is arranged on, between rear two groups of columns, when back timber adjusts inclination angle, using the junction point of quadric chain and back timber as fulcrum, back timber and quadric chain form seesaw structure, adjust the most from front to back or from rear to the front larger angle that is all capable of, simultaneously, before, back timber is supported by rear two groups of support posts and quadric chain simultaneously, make structure of the present utility model more stable, supporting intensity meets the demand of the typically complicated fully-mechanized mining working of operating mode.The advantages such as down-hole of the present utility model support frame is compared with face end support of the prior art, simple and light, and reliability is high, it is simple to operation, low cost of manufacture.For general fully-mechanized mining working, tip position simple in construction, the uncomplicated situation of geological conditions can replace the effect of hydraulic prop completely, make Roof relatively reliable.This light support frame simple in construction, uses and easy to maintenance, is arranged on coal mine down-hole tunnel and work surface junction, provides safe and reliable space for scratch board conveyor, pedestrian's walking and operation.

Fig. 3 is the structural representation of this utility model down-hole support frame embodiment 2.
Detailed description of the invention
Below in conjunction with the accompanying drawings embodiment of the present utility model is described further.
This utility model down-hole support frame is a kind of lightweight down-hole support frame, can adapt to the work requirements of the general fully-mechanized mining working of operating mode, can either meet down-hole supporting intensity requirement simple in construction again, and maintenance cost is low.
The embodiment 1 of lightweight down-hole support frame, as depicted in figs. 1 and 2, this down-hole support frame includes base 7, it is provided with back timber 1 by support post and quadric chain top on base 7, support post is provided with two groups along base time interval, it is respectively front column 2 and rear column 4, front column 2 and rear column 4 are scalable column, quadric chain is between front column 2 and rear column 4, quadric chain includes connecting rod 3, front rod 5 and back link 6, the upper end of upper connecting rod 3 is hinged with back timber 1, the upper end of front rod 5 and back link 6 is hinged with upper connecting rod 3, lower end is hinged with base 7.
Base 7 middle-grade is provided with advancing jack 10 that telescopic direction extends to front-rear direction and the push rod 9 that axis extends along the longitudinal direction, and the rear end of advancing jack 10 is hinged with base, and front end is hinged with the rear end of push rod 9.Base 7 front end is arranged over lifting end jack 8 in push rod, for upwards jack-up base；In the present embodiment, it is installed with otic placode on base 7, the upper end lifting end jack 8 is hinged with otic placode by jointed shaft, the lower end lifting end jack 8 is free end, when lifting end jack 8 and being in contraction state, lift end jack and be in hang, when push rod elapses forward when lifting the elongation of the end jack while, lift end jack to rotate around jointed shaft, when again shrinking, hang can be automatically returned to.
In the present embodiment, front column about 2 is arranged at intervals with two, and rear column about 4 is arranged at intervals with two, and two front columns, two rear columns form corner and support, and quadric chain is positioned at the center position that corner supports, and makes support more stable.Owing to the quadric chain of down-hole support frame is arranged between front column and rear column, when adjusting back timber inclination angle, seesaw structure is formed for fulcrum with the junction point of quadric chain with back timber, the high inclination-angle being so capable of former and later two directions of back timber adjusts, the topographic features complicated to adapt to mining coal seam.
The embodiment 2 of lightweight down-hole support frame, as it is shown on figure 3, the structure of this down-hole support frame is compared with the structure in embodiment 1, difference is: the quadric chain of this down-hole support frame is oppositely arranged.In the present embodiment, the lower end of quadric chain is hinged with base 7 ', in opposite direction with embodiment 1 of the folding direction of quadric chain.
