Background technology
Our usually alleged all operations on horizontal surface of hoisting crane at present, the operation of promptly non-ramp is even the gradient slightly generally also is no more than 5 ° the gradient.As the need heavy work of hanging oneself in the ramp of great slope, existing hoisting crane will because of himself unbalance can not operation.
Summary of the invention
Along with the development of building cause and the variety of construction operating mode, need on the ramp, the situation of hoisting operation day by day increase, for example need on the steel braced arch, lifting set a roof beam in place, or need on the ramp, play heavy equipment etc., and existing hoisting crane can not satisfy the job requirements of this type of operating mode.Therefore in order to solve the problem of the heavy work of can not hanging oneself in the ramp that has the hoisting crane existence now, the utility model proposes double-deck chassis structure and hoisting crane levelling gear technical scheme, solve the existing unbalance problem of hoisting crane ramp lift heavy self, thereby realize that this hoisting crane can be at 50 ° with the hang oneself target of heavy work of internal ramp.
The utility model can be on the ramp hoisting crane technical scheme of lift heavy as follows:
1. can be on the ramp hoisting crane of lift heavy, comprise tackling system, the double bottom disc mechanism, levelling gear, rope traction running mechanism and anchoring mechanism, it is characterized in that the double bottom disc mechanism is by top bottom-disc (1), low bottom-disc (2) is formed, tackling system (3) is installed on the top bottom-disc (1), low bottom-disc (2) is equipped with away driving wheel (4), traction displacement node (5) and anchoring mechanism (6), the front portion of top bottom-disc (1) and low bottom-disc (2) is connected with rotation hinge (7), and a pair of spiral levelling gear (8) is equipped with at the rear portion of top bottom-disc (1) and low bottom-disc (2) makes top bottom-disc keep horizontality.
2. can be on the ramp hoisting crane of lift heavy, it is characterized in that described a pair of spiral levelling gear (8) is made up of screw rod (9), big gear wheel (11) and motor (12), the bottom of screw rod (9) is connected with low bottom-disc (2) with hinge (10), screw rod (9) and top and the big gear wheel (11) that is installed in top bottom-disc (1) are connected, big gear wheel (11) at motor (12) but left rotation and right rotation under driving, drive top bottom-disc (1) and connect hinge (7) rotation around upper and lower chassis, make top bottom-disc (1) maintenance level.
3. can be on the ramp hoisting crane of lift heavy, it is characterized in that drawing anchor (13) before the described anchoring mechanism (6) that is installed in low bottom-disc (2) comprises anterior top (14) and post-tensioning anchor (15).
The utility model hoisting crane levelling gear is simple and direct flexibly, and control is convenient, and is practical, and safeguards simple.The hoisting crane top bottom-disc can change with foundation slope and keep horizontality, has solved hoisting crane self unbalance problem during lift heavy on the ramp, and the section assembling that successfully is used for steel arch bridge sets up, and its technology and economic effects are fairly obvious.

Specific embodiments
The utility model tackling system is in normal working, the traction displacement node (5) of hoisting crane low bottom-disc (2) is subjected to rope traction, walking wheel (4) by low bottom-disc (2) is at the ramp superior displacement, in shifting process, constantly top bottom-disc is carried out horizontal adjustment by spiral levelling gear (8), keep top bottom-disc (1) to be in visual derection level as far as possible, i.e. positive and negative rotation by motor (12) passes motion to big gear wheel (11), drive top bottom-disc (1) by worm drive then and connect axle (2) rotation, make top bottom-disc (1) maintenance level around last low bottom-disc.
After hoisting crane arrives the operation position,, make away driving wheel unsettled, finish anterior grappling and rear portion grappling, unclamp haulage cable with manual anterior top (14), a top, oil top, with level indicator, accurately finish the horizontal adjustment of top bottom-disc (1) after, carry out hoisting operation.After finishing hoisting operation, unclamp anterior top (14) and post-tensioning anchor (15), the tensioning haulage cable draws anchor (13) before unclamping then.
Example 1:
When building certain steel arch bridge, flat segments and arch dam intersection at steel arch bridge, the hoisting crane erect-position is on flat segments, at first set up first, second internode (the arch dam gradient is 35 °) of steel arch bridge, hoisting crane reach climbing then, be the traction displacement node (5) of rope traction hoisting crane low bottom-disc (2), by walking wheel (4) at the ramp superior displacement.In shifting process, drive big gear wheel (11) rotation by motor (12), the worm drive of big gear wheel drive top bottom-disc (1) around last low bottom-disc connection hinge (2) rotation then, make top bottom-disc (1) maintenance level, when hoisting crane was advanced to first internode of arch bridge, the angle of last low bottom-disc reached 35 °.
After hoisting crane is advanced between first segment,, make walking wheel (4) unsettled with anterior top (14) of manual jack stand, draw anchor (13) and post-tensioning anchor (15) before fixing, unclamp haulage cable, accurately adjust again, make top bottom-disc (1) maintenance level, promptly carry out hoisting operation.After installing the steel arched girder of a sections, top (14) and post-tensioning anchor (15) before unclamping, the tensioning haulage cable draws anchor (13) before unclamping then.Sections of traveling forward again.A sections is installed like this, and the sections that advances is finished the whole process of setting a roof beam in place.
