Technical field
The utility model is related to a kind of constructing devices in tunnel or underground engineering, more particularly to one kind being used for tunnel
Or the hoist engine of underground engineering drives inverted arch trestle.
Background technology
With the mechanization of drill+blast tunnel excavation construction operation, automation is promoted, and progress of excavating the moon has approached 400 and prolonged
Rice.And inverted arch lining construction progress seriously falls behind excavation construction, leading to safe cloth, this requires make away from exceeded influence construction safety
With the mobile inverted arch construction bridge more grown up, this trestle is longer than existing trestle, heavier, to the mobile mechanism of trestle
It puts forward higher requirements.
Current existing trestle driving mechanism is divided into 2 kinds：1, crawler type driving is rotated by crawler belt provides trestle walking power.
Such as, the crawler type walking mechanism based on trestle trolley disclosed in China Patent No. " 201521084497.6 ", publication date 2016-
06-29.2, in-wheel driving provides trestle walking power by tyre rotation.
Main problem is as follows existing for above-mentioned several existing trestles：1, above 2 kinds due to crawler belt or larger turn of diameter of tyres
Speed it is relatively low thus need to use large torque hydraulic motor driving or big retarding than retarder, lead to complicated integral structure, exist
The defect of field maintenance difficulty after the high ﹑ of the big ﹑ energy consumptions of Cheng Bengao ﹑ occupied spaces breaks down；2, when constructing tunnel, trestle cooperation is faced upward
Arch template using when trestle on also need the trolley that mobile inverted arch template is set, the driving mechanism of trestle that cannot double as trolley driving machine
Structure, thus also need to the driving device of a set of trolley movement.
Invention content
The purpose of the utility model is to overcome the above problems existing for existing trestle, provide a kind of hoist engine driving inverted arch
Trestle.The utility model is driven using hoist engine, which can drive movable trestle, can also drive be arranged on trestle it is small
Vehicle moves, and dual-use simplifies the driving device of existing trestle, cost-effective, while reducing trestle operation difficulty reduction work
People's labor intensity.
To achieve the above object, the technical solution adopted in the utility model is as follows：
A kind of pre-walking mechanism for being arranged on hoist engine driving inverted arch trestle, including trestle, front leg strut, rear walking mechanism and
Rear base, pre-walking mechanism include mobile supporting leg, mobile jacking cylinder and sliding slot, and mobile supporting leg passes through mobile jacking cylinder and cunning
Slot is slidably connected, it is characterised in that：Further include hoist engine, the sliding slot upper and lower ends are respectively arranged with one group of traveling wheel, upper end
One group of traveling wheel and trestle top surface on track coordinate, one group of traveling wheel and the track on trestle bottom surface of lower end coordinate, sliding
Slot is limited by upper and lower two groups of traveling wheels on trestle, and hoist engine is arranged in trestle rear end, the traction chain of hoist engine or traction
Steel cable is hinged on the chute.
The hoist engine is two groups, corresponds to two groups of pre-walking mechanisms respectively, and two groups of hoist engines are separately positioned on trestle both sides.
The traction chain or traction steel rope of cable movement locus of the trestle two side upper edge hoist engine are provided with guide wheel.
The sliding slot upper and lower ends have been respectively fixedly connected with walker, and there are two traveling wheels for setting on each walker.
The traction chain or traction steel rope of cable pass through the drive sprocket of hoist engine, pass through guide wheel, both ends respectively with before sliding slot
A closed loop chain is hingedly formed afterwards.
Using the utility model has the advantage of：
Two groups of elevator machine actuating devices of the utility model use the driving wheel of small diameter, in same trestle movement speed
When, there can be higher rotating speed, because of the retarder of hydraulic motor or high reduction ratio without huge discharge, save and be manufactured into
This；Hoist engine drives trestle movement by fixed pre-walking mechanism, and the movement of driving pre-walking mechanism, realizes one when fixing trestle
Machine is dual-purpose, and control system is simplified while having saved manufacturing cost, reduces the operation difficulty of worker；Total simply may be used
It leans on, is easy repair, favorably improves construction speed.
