Abstract
The utility model discloses a rear supporting arm of a cantilever type excavator, relating to the cantilever type excavator. The rear supporting arm mainly comprises a fixed disc, a rotary disc, a supporting lug, a hydraulic oil cylinder and a supporting body, wherein the fixed disc is arranged at the upper end of the rotating disc by a connecting shaft; the supporting lug is fixedly connected with the lower end surface of the rotating disc; a supporting sleeve arranged at the front end of the supporting body is connected with the lower end of the supporting lug, and an oil cylinder reinforcing sleeve arranged at the rear end of the supporting body is connected with the upper end of the supporting lug by the hydraulic oil cylinder. The supporting mechanism is arranged at the rear end of a comprehensive excavator, and when a slope is generated on the ground, an ejector rod is driven to act by the hydraulic oil cylinder, thus driving the supporting body to move downward, effectively preventing the whole slope and improving the stability of the whole machine; secondarily, the fixed disc is connected with a rack and the rotating disc is connected with the fixed disc by a rotating shaft, when the side edge in a coal seam is higher, the angle of the rotating disc is adjusted, and after the hydraulic oil cylinder acts, the side edge is supported by the supporting body, thus effectively preventing side slipping and guaranteeing the safety of operators of the coal seam.
Description
Technical field
The utility model relates to a kind of boom-type roadheader, specifically a kind of back support arm of boom-type roadheader.
Background technology
Boom-type roadheader is a kind of efficient heading equipment that integrates cutting, loading, transhipment etc., be widely used in fields such as traffic, tunnel, mining, compare with large-scale development machine, little, the lightweight characteristics of volume are arranged, be applicable to the operation of medium and small colliery, improve the mechanization level, development machine is when work, because the vibrations that produce are bigger, development machine supports unstable, easily slide, jeopardize equipment and personal safety, especially when the upward slope operation, easier generation, therefore need be when the development machine operation, a kind of parts that can the stable support development machine are provided.The support arm of conventional development machine only can up-down adjustment, yet the coal seam tends to occur the higher situation of side edge, thereby causes development machine the sideslip phenomenon to occur, and therefore conventional support arm occurs regulating ineffective, and the situation that jeopardizes personal safety occurs repeatedly.
The utility model content
The utility model wants the technical solution problem to provide a kind of back support arm of boom-type roadheader, supporting ﹠ stablizing not only, and can effectively prevent the generation of development machine sideslip phenomenon.
The utility model is for solving the problems of the technologies described above, the technical scheme that is provided is: a kind of back support arm of boom-type roadheader, mainly form by fixed disk, rolling disc, journal stirrup, hydraulic jack and supporter, fixed disk is arranged on the rolling disc upper end by connecting axle, journal stirrup is fixedlyed connected with the lower surface of rolling disc, the support set that the supporter front end is provided with is connected with the journal stirrup lower end, and the oil cylinder reinforcing sleeve that its rear end is provided with is connected with the journal stirrup upper end by hydraulic jack.
Support set described in the utility model is connected with bearing pin with journal stirrup.
Journal stirrup described in the utility model, its shape is del.
The beneficial effects of the utility model are: in the fully-mechanized digging machine rear end supporting mechanism is set, supporting mechanism is by being provided with fixed disk and rolling disc, and it is connected with the fully-mechanized digging machine body, when the slope appears in ground, drive the push rod action by hydraulic cylinder, move downward thereby drive supporter, effectively prevent whole slope, improve the stability of complete machine; Secondly, fixed disk is connected with frame, and rolling disc is connected with fixed disk by axis of rotation, when occurring side in the coal seam when higher, regulate the angle of rolling disc, after the hydraulic cylinder action, by support body supports work side, effectively prevent to break away, guaranteed coal seam staff's safety.
Description of drawings
Figure is a structural representation of the present utility model.
Mark among the figure: 1, fixed disk, 2, rolling disc, 3, journal stirrup, 4, hydraulic jack, 5, supporter, 6, connecting axle, 7, support set, 8, the oil cylinder reinforcing sleeve, 9, linking arm.
The specific embodiment
As shown in the figure, a kind of back support arm of boom-type roadheader, mainly by fixed disk 1, rolling disc 2, journal stirrup 3, hydraulic jack 4 and supporter 5 are formed, fixed disk 1 is arranged on rolling disc 2 upper surfaces by connecting axle 6, journal stirrup 3 is fixedlyed connected with the lower surface of rolling disc 2, the support set 7 that supporter 5 front ends are provided with is connected with journal stirrup 3 lower ends, the oil cylinder reinforcing sleeve 8 that the rear end is provided with is connected with journal stirrup 3 upper ends by hydraulic jack 4, it belongs to independently braced structures, can be arranged on the both sides of development machine rear end, fixedly connected with frame and get final product by being arranged on linking arm 9 on the fixed disk 1, can prevent effectively that both sides from sliding, guarantee the stability of complete machine.
Journal stirrup 3 described in the utility model, its shape is del.
In both sides, boom-type roadheader rear end this supporting mechanism is set respectively, supporting mechanism is by being provided with fixed disk and rolling disc, and it is connected with the fully-mechanized digging machine body, when the slope appears in ground, move by hydraulic jack, move downward thereby drive supporter, effectively prevent whole slope, improve the stability of complete machine; Secondly, fixed disk is connected with frame, rolling disc is connected with fixed disk by axis of rotation, when occurring side in the coal seam when higher, after regulating the angle of rolling disc, adopt pin that fixed disk and rolling disc are fixed, the hydraulic cylinder action side by support body supports, effectively prevent to break away, guaranteed coal seam staff's safety.
