Drop bar side face is hinged with support rod, and the support rod is withstood in card slot far from one end of hinged place, and the support plate upper surface is set
There are multiple springs, the spring top is equipped with auxiliary support plate.
Further, the support rod is equipped with telescopic spring device far from one end of hinged place.
Further, the auxiliary support plate is supporting mesh.
Further, the bottom of the hinged place of two support plates is equipped with set casing, and the set casing and support plate are logical
Bolt is crossed to be fixedly connected.
The prior art is compared, the utility model has the beneficial effects that:
The original state of the device is the folded state in M type, after being put into tunnel, two bottom plates are mobile to both sides,
Make device in п type, bearing height is then adjusted by the hydraulic lifting arm of two sides, until the spring at top is all by Auxiliary support
Until plate is squeezed and deformed, then by support rod top to card slot, suspension device is provided with, when as temporary support device,
The folding device be can be convenient into movement at M type, while the combination of the auxiliary support plate and spring at the top of support plate, it can be to lane
More comprehensive supporting effect is played on out-of-flatness surface at the top of road, guarantees the firm of tunnel top palisades, guarantees staff's
Safety.

Specific embodiment
The present invention will be further illustrated below in conjunction with specific embodiments.It should be understood that these embodiments are merely to illustrate this
Utility model rather than limitation the scope of the utility model.In addition, it should also be understood that, in the content for having read the utility model instruction
Later, those skilled in the art can make various changes or modifications the utility model, and such equivalent forms equally fall within this Shen
It please limited range.
Described in the utility model is a kind of coal mine driving suspension device, and main structure includes bottom plate 1, and the bottom plate 1 has two
It is a and arranged symmetrically, weight can be installed on bottom plate 1 additional to increase the stability of device, be respectively fixed on the bottom plate 1 hydraulic
Elevating lever 2, two hydraulic lifting arms 2 can be gone up and down simultaneously, and can reduce the labor intensity of worker with remote control, reduce danger
It is dangerous, link block 3 is respectively fixed at the top of the hydraulic lifting arm 2,3 side of link block has been respectively articulated with support plate 4, branch
The width of fagging 4 can be more relatively wide, improves the stability of supporting, and two 4 opposite sides of support plate are arranged, and described in two
Support plate 4 is hinged, realizes device foldable, is moved easily, 4 bottom surface of support plate is respectively equipped with card slot 5, the hydraulic liter
Drop bar 2 has been hinged at support rod 6, and the support rod 6 is withstood in card slot 5 far from one end of hinged place, improves support plate 4 and supports
Stability, 4 upper surface of support plate be equipped with multiple springs 7,7 top of spring be equipped with auxiliary support plate 8, support plate 4
It can choose flexible material, by multiple independent auxiliary support plates 8, the concave point at the top of tunnel can be supported, it can be with
Supporting comprehensively more is carried out to the top of tunnel out-of-flatness.
Since the length of support rod 6 is fixed, for some higher or shorter tunnel top, support rod 6 cannot
It is withstood in card slot 5 well, the support rod 6 is equipped with telescopic spring device far from one end of hinged place, and telescopic spring device can
