Description
Technical field:
The utility model relates to the hydraulic support technical field, is specifically related to split back timber unsplit bedplate four posts and supports hydraulic chock.
Background technology:
Existing hydraulic support all things considered mainly comprises two big types: suspension moving hydraulic support, comprehensive mining hydraulic bracket.Suspended type hydraulic support has advantages such as volume is little, in light weight, easy transportation and installation, flexible movements, but owing to is connected the overall operation face through joist between back timber and the back timber and fuses, has promptly increased the complexity of structure, and top board is required height, poor stability; Because column directly acts on base plate, base plate is required height again, be prone to prick at the end, pushing and sliding move the frame inconvenience.Fully mechanized mining supporter has overcome the above-mentioned shortcoming of integral top beam combined suspension moving support, but have that volume is big, weight is big, the transportation difficult installation, to defectives such as mine laneway requirement height, cost height.Therefore in the actual use of mine, particularly press for a kind of novel support apparatus that has above-mentioned two kinds of hydraulic support advantages simultaneously in medium and small girdle colliery.
The utility model content:
The purpose of the utility model provides split back timber unsplit bedplate four posts and supports hydraulic chock; It is simple in structure, in light weight, good stability, to roof and floor require low, particularly excellent its of aboveground dismounting easy transportation and installation down is that the support colliery that is not easy to for a short time to go into the well for the well that middle small mine is not transformed is very strong, brought into play its unique advantage for 1 meter following Bracket in Thin Coal Seam especially.
In order to solve the existing problem of background technology; The utility model is to adopt following technical scheme: it comprises back timber assembly 1, left back timber 2, right back timber 3, column 4, base 5, tail boom 6, small rod 7, big connecting rod 8, bearing pin 9, big bearing pin 10, right beam fixed head 11, left beam fixed head 12, the solid frame 13 of column U type, column baffle plate 14, column limiting plate 15, passes jack 16, slide rail 17, transfers the frame jack 18 and the end to transfer beam 19; The left end of back timber assembly 1 is provided with left back timber 2; The right-hand member of back timber assembly 1 is provided with right back timber 3; Four root posts 4 are hinged with left back timber 2 and right back timber 3 respectively, and four root posts 4 are hinged with base 5, and the rear end of left back timber 2 and right back timber 3 is provided with tail boom 6 respectively; Between a left side back timber 2 and the right back timber 3 through small rod 7, big connecting rod 8, bearing pin 9 and greatly bearing pin 10 be connected; Left side back timber 2 is connected with left beam fixed head 12, and right back timber 3 is connected with right beam fixed head 11, and base 5 is provided with the solid frame 13 of column U type; Be respectively arranged with column baffle plate 14 and column limiting plate 15 in the solid frame 13 of column U type; And the centre of base 5 is provided with passes jack 16, and a side of base 5 is provided with slide rail 17, and its opposite side is provided with end accent beam 19 and transfers frame jack 18.
The utility model is got its chief, is gone its shortage to cantilever support and fully mechanized mining supporter pluses and minuses separately, has characteristics such as simple in structure, in light weight, good stability,, easy transportation and installation low to the roof and floor requirement, flexible movements, cost are low.

The specific embodiment:
With reference to Fig. 1-Fig. 4; This specific embodiment adopts following technical scheme: it comprises back timber assembly 1, left back timber 2, right back timber 3, column 4, base 5, tail boom 6, small rod 7, big connecting rod 8, bearing pin 9, big bearing pin 10, right beam fixed head 11, left beam fixed head 12, the solid frame 13 of column U type, column baffle plate 14, column limiting plate 15, passes jack 16, slide rail 17, transfers the frame jack 18 and the end to transfer beam 19; The left end of back timber assembly 1 is provided with left back timber 2, and it is hinged with left back timber 2 and right back timber 3 respectively that the right-hand member of back timber assembly 1 is provided with right back timber 3, four root posts 4; And four root posts 4 are hinged with base 5; The rear end of left side back timber 2 and right back timber 3 is provided with tail boom 6 respectively, between left back timber 2 and the right back timber 3 through small rod 7, big connecting rod 8, bearing pin 9 and greatly bearing pin 10 be connected, left back timber 2 is connected with left beam fixed head 12; Right back timber 3 is connected with right beam fixed head 11; Base 5 is provided with the solid frame 13 of column U type, be respectively arranged with column baffle plate 14 and column limiting plate 15 in the solid frame 13 of column U type, and the centre of base 5 is provided with passing jack 16; One side of base 5 is provided with slide rail 17, and its opposite side is provided with end accent beam 19 and transfers frame jack 18.
Described left back timber 2, right back timber 3 and base 5 are a case structure respectively, are the main pressure-containing members of support, and the pressure that left back timber 2, right back timber 3 bear from top board leans on four root posts 4 to support, and power is delivered on the base 5 the most at last.During work column 4 stretch out drive left back timber 2, right back timber 3 moves upward; The column support skews and plays the effect of crux property when preventing going up and down under the effect of the solid frame 13 of the column U type on base 5 and column baffle plate 14, column limiting plate 15, is raised to the back, position at back timber and makes support contact each protuberance of top board stably through small rod 7, big connecting rod 8 and bearing pin 9, big bearing pin 10 mutual rotations.Simultaneously afterbody is equipped with tail boom 6 and prevents to fall the coal bar and pour in support behind back timber.Side at base 5 is equipped with slide rail 17, and its opposite side is equipped with the end accent beam 19 of transferring frame, and its effect is to prevent to be hinged through handling the distance of transferring frame jack 18 to stretch out and regaining between the adjustment support.Thereby this specific embodiment has guaranteed the roof supporting that support is stable in sum; In the centre of base 5 a passing jack 16 being installed links to each other with scratch board conveyor; Handle to pass jack 16 after producing coal and make the transporter step pitch of advancing when blowing out; Fall and pass under the jack 16 retracting force effects step pitch of drive support reach behind the frame again and accomplished a circulation, so efficient, safe repeatedly completion coal mining task.
This specific embodiment is got its chief, is gone its shortage to cantilever support and fully mechanized mining supporter pluses and minuses separately, has characteristics such as easy to use simple in structure, in light weight; Be convenient to the aboveground transportation of dismounting down, special centering small mine and girdle coal-mining method provide a kind of brand-new support apparatus.
