Abstract
The invention relates to a rear support mechanism of a continuous coal cutter. The rear support mechanism of the continuous coal cutter comprises a coal cutter body rack, rear support frame bodies, support oil cylinders and a pair of parallel conveyor lifting cylinders, wherein one end of each rear support frame body is hinged with the coal cutter body rack by a pin shaft; and two ends of the conveyor lifting cylinders are respectively hinged with a conveyor and the coal cutter body rack through pin shafts. The rear support mechanism of the continuous coal cutter is characterized in that a pair of parallel support oil cylinders and a pair of parallel rear support frame bodies are arranged in the rear support mechanism; the axle lines of the support oil cylinders are consistent with the trends of the axle lines of the conveyer lifting cylinders; and two ends of the support oil cylinders are respectively hinged with the coal cutter body rack and the rear support frame bodies through pin shafts.
Description
Technical field
The present invention relates to a kind of continuous miner rear support mechanism.
Background technology
Along with the continuous miner successful Application of mine at home, more and more mines adopt continuous miner to carry out tunnelling, continuous miner rear support Main Function is when the coal machine is worked, equipment is propped up, prevent that continuous miner is due to when cut hard coal or the dirt band, because the walking driving force is not enough, equipment is slided backward, in the time of also can alleviating due to cut simultaneously, high vibration causes the hidden danger of equipment fault.in the continuous miner rear support mechanism that uses at present, generally adopt single oil cylinder to support the rear support support body, they generally design according to U.S.'s JOY corporate structure, their rear support structure as depicted in figs. 1 and 2, as seen from the figure, in this rear support mechanism, a pair of transporter hoist cylinder 4 and a support cylinder 2 discharge side by side, wherein, transporter hoist cylinder 4 two ends are hinged by bearing pin and transporter 5 and coal-winning machine body frame 1 respectively, one end of rear support support body 3 also is hinged on coal-winning machine body frame 1 by bearing pin, their axis perpendicular intersects, be positioned on the same cross section of coal-winning machine body frame 1, because transporter hoist cylinder 4 is positioned at both sides, the pin joint of leaving support cylinder 2 for can only be between a pair of transporter hoist cylinder 4, due to the restriction that is subject to the installation site, cylinder body can not be accomplished very large, and a rear support support body 3 can only be set.This form of structure causes rear support, and during at cut high rigidity coal petrography, when needing rear support that supplemental support is provided, not only support force is not enough for a rear support support body 3, and stability is also poor, will inevitably affect the continuous miner normal operation when continuous miner.
Summary of the invention
The object of the invention is, the defects that exists on the continuous miner rear support mechanism structure for present use provides a kind of new continuous miner rear support mechanism.
the object of the present invention is achieved like this: a kind of continuous miner rear support mechanism, comprise coal-winning machine body frame, the rear support support body, support cylinder and a pair of transporter hoist cylinder arranged side by side, rear support support body one end is hinged on coal-winning machine body frame with bearing pin, the two ends of transporter hoist cylinder are hinged by bearing pin and transporter and coal-winning machine body frame respectively, it is characterized in that: in rear support mechanism, a pair of support cylinder arranged side by side and a pair of rear support support body arranged side by side are arranged, the axis of support cylinder is consistent with the axis trend of transporter hoist cylinder, the support cylinder two ends are hinged by bearing pin and coal-winning machine body frame and rear support support body respectively.
In the present invention: support cylinder one end is hinged by bearing pin and coal-winning machine body frame, and the other end is hinged by bearing pin and rear support support body middle part.
The invention has the advantages that: because the axis of support cylinder is consistent with the trend of transporter hoist cylinder axis, avoided the installation site that traditional rear support structure is kept for support cylinder fully.Owing to having adopted a pair of support cylinder arranged side by side and a pair of rear support support body arranged side by side, can make coal-winning machine obtain larger support force, have simultaneously better stability.Be positioned at the middle part of rear support support body due to a pin joint of support cylinder, can be when support cylinder has less telescopic variation, just can change the amplitude of variation between coal-winning machine body frame and the rear support support body strong point, improve the Operational Figure Of Merit of support cylinder.Avoided the installation site of transporter hoist cylinder due to the installation site of support cylinder, safeguarded convenient.

Fig. 1 is the structural representation that has rear support mechanism now.
Fig. 2 be in Fig. 1 A-A to the schematic diagram of plan structure.
Fig. 3 is embodiment of the present invention structural representation.
Fig. 4 be in Fig. 3 B-B to the schematic diagram of plan structure.
In figure: 1, coal-winning machine body support body, 2, support cylinder, 3, the rear support support body, 4, the transporter hoist cylinder, 5, transporter.
The specific embodiment
Fig. 3, Fig. 4 disclose the concrete structure of the embodiment of the present invention without limitation, below in conjunction with accompanying drawing, the present invention are done to describe further.
As seen from Figure 4, the present invention includes coal-winning machine body frame 1, rear support support body 3, a pair of support cylinder 2 arranged side by side and a pair of transporter hoist cylinder 4 arranged side by side, rear support support body 3 one ends are hinged on coal-winning machine body frame 1 with bearing pin, the two ends of transporter hoist cylinder 4 are hinged by bearing pin and transporter 5 and coal-winning machine body frame 1 respectively, the axis trend of the axis of support cylinder 2 and transporter hoist cylinder 4 is consistent, and support cylinder 2 two ends are hinged by bearing pin and coal-winning machine body frame 1 and rear support support body 3 respectively.In the present embodiment, the pin joint of support cylinder 2 and rear support support body 3 is positioned at the middle part of rear support support body 3.
