Utility model content
For the weak point existing in above-mentioned technology, the utility model provides one can reduce labor strength, steelframe lifting, the positioner of increasing work efficiency.
For achieving the above object, the utility model provides a kind of tunnel steelframe stand lifter, comprises steelframe pallet, fixed track deferent, lift rail deferent, pulley structure and slide fastener for jacking steelframe; The upper end of described fixed track deferent is provided with fixing hanger, and described fixing hanger below is provided with chute; Described lift rail deferent is contained in fixed track deferent, and vertically slides on can be in fixed track deferent, and the below of described lift rail deferent is provided with lifting hanger, and described lifting hanger is through chute; Described pulley structure is fixed on fixing hanger, and one end of described slide fastener is fixed on and promotes on hanger, and the other end is through pulley structure; Described steelframe pallet is fixed on the top of lift rail deferent; Described pulley structure is the Chain block with reverse check braking action.
Wherein, the end of described slide fastener is provided with hook, and described hook is provided with anticreep spring stop piece.
Wherein, the bottom of described fixed track deferent is provided with support baseboard.
Wherein, the bottom of described support baseboard is provided with many equally distributed taper inserted links.
The beneficial effects of the utility model are: the tunnel steelframe stand lifter that the utility model provides, and simple in structure, cost of production is low; Convenient to operation, be easy to grasp: steelframe is placed on to steelframe pallet, pulls slide fastener downwards, and then make to promote hanger upward sliding in chute, promote simultaneously hanger drive lift rail deferent in fixed track deferent on slide, reach the effect that promotes steelframe.
Compared to traditional pure handwork, the operating efficiency of the tunnel steelframe stand lifter that the utility model provides is higher, can significantly shorten the activity time of the artificial stand process in present mine excavation tunnel, when shortening activity time, also reduced workman for a long time in not forming the potential safety hazard existing under the exposed rock formation of preliminary bracing, in addition, also greatly reduce labour intensity, save operator's muscle power.
Particularly importantly, pulley structure of the present utility model is the Chain block with reverse check braking action, can realize the rising of steelframe, also can realize the decline of steelframe, facilitates steelframe location; And Chain block can accomplish to stop fixing, also improve the safety of equipment, prevent accident; Chain block is also a kind of work-saving device, can reduce labour intensity.

Detailed description of the invention
In order more clearly to explain the utility model, below in conjunction with accompanying drawing, the utility model is further described.
Refer to Fig. 1 and Fig. 2, the tunnel steelframe stand lifter that the utility model provides, comprises steelframe pallet 11, fixed track deferent 12, lift rail deferent 13, pulley structure 14 and slide fastener 15 for jacking steelframe; The upper end of fixed track deferent 12 is provided with fixing hanger 121, and fixing hanger 121 belows are provided with chute 122; Lift rail deferent 13 is contained in fixed track deferent 12, and can on fixed track deferent 12 is interior, vertically slide, and the below of lift rail deferent 13 is provided with and promotes hanger 131, promotes hanger 131 through chute 122; Pulley structure 14 is fixed on fixing hanger 121, and one end of slide fastener 15 is fixed on and promotes on hanger 131, and the other end is through pulley structure 14; Steelframe pallet 11 is fixed on the top of lift rail deferent 13; Pulley structure 14 is for having the Chain block of reverse check braking action.
In the present embodiment, pulley structure 14 is for having the Chain block of reverse check braking action.Chain block cry again chain block, jin do not fall, bottle gouard moved by hands, be a kind of Manual hoisting machinery simple, easy to carry that uses, also claim " ring-chain hoist " or " jack ".The operating principle of Chain block is: upwards when lifting heavy, drop clockwise manual-chain, hand sprocket rotation, when decline, drop counterclockwise and pull chain, Brake Block separates with brake block, ratchet is static under the effect of ratchet, five tooth major axis drive chain hoist wheel reverse direction operation, thereby steadily decline weight.
The tunnel steelframe stand lifter that the utility model provides, simple in structure, cost of production is low; Convenient to operation, be easy to grasp: steelframe is placed on to steelframe pallet 11, pulls slide fastener 15 downwards, and then make to promote hanger 131 at the interior upward sliding of chute 122, promote hanger 131 simultaneously and drive lift rail deferent 13 at the interior upward sliding of fixed track deferent 12, reach the effect that promotes steelframe.
