Abstract
The utility model relates to a steering mechanism for scissor -fork type aerial work platform, the control handle lower part turns to arm and elasticity cylindric lock fixed connection steering spindle the for with to turn to the arm articulated with round pin axle, turns to rocker and the fixed whole of welding into in steering spindle lower part, and steering connecting rod one end is with to turn to the rocker articulated, and the other end and directive wheel swing arm articulate. The utility model discloses the during operation, the operation personnel stimulate the control handle horizontal hunting forward, drive and turn to the corresponding horizontal hunting of rocker, and steering connecting rod promotes or pulling directive wheel turn right or left to realize left and right turning to. The utility model discloses an it is preceding in the center of rotation with steering connecting rod's pin joint to turn to the rocker, has realized the swing direction of control handle and the unanimity of the rotation direction of directive wheel. The utility model discloses simple structure, transmission power is direct, and the manipulation turns to in a flexible way light.
Description
Technical field
This utility model relates to a kind of steering mechanism for scissor aerial work platform.
Background technology
Scissor aerial work platform 9 (see Fig. 3) is relatively big due to deadweight, general from focusing on more than 1000Kg.Fig. 4 sees in the steering mechanism of tradition scissor aerial work platform 9, its control crank 1 bottom and steering arm 2 hinge, steering arm 2 is connected with elastic cylindrical pin is fixing with steering spindle 3, pitman arm 10 is fixing with steering spindle 3 bottom is welded into entirety, turn to push-pull bar 11 one end hinged with pitman arm 10, the other end is hinged with rocking arm 12, rocking arm 12 is arranged on the fixing hinge in the middle of the steeraxle of chassis, rocking arm 12 is hinged with short connecting rod 13 one end, short connecting rod 13 other end is hinged with the wheel swing arm of side deflecting roller and long connecting rod 14, long connecting rod 14 two ends are hinged with both sides deflecting roller swing arm, its structure is complicated.
When need to turn to, operator are pulled along control crank 1 and swing, and drive pitman arm 10 to swing accordingly, turn to push-pull bar 11 to pull or promote rocking arm 12 rotary oscillation; rocking arm pulls or promote short connecting rod, drive long connecting rod 14, make the most corresponding rotation of left and right turn 6.Because of control crank 1 steering arm to be passed through 2, pitman arm 10, turning to push-pull bar 11, rocking arm 12, short connecting rod 13, long connecting rod 14 and deflecting roller swing arm to handle deflecting roller 6 and turn to, transmission power friction motion transition loss is big, turn to relatively be stranded difficult and laborious.
Summary of the invention
The purpose of this utility model is for above-mentioned present situation, it is desirable to provide a kind of simple in construction, and transmission power is direct, handles and turns to the lightest steering mechanism for scissor aerial work platform.
The implementation of this utility model purpose is, steering mechanism for scissor aerial work platform, control crank bottom and steering arm hinge, steering arm is fixing with steering spindle elastic cylindrical pin to be connected, turn to rocker to fix with steering shaft lower portion and be welded into entirety, steering link one end is with to turn to rocker hinged, and the other end is hinged with deflecting roller swing arm.
During utility model works, operating personnel is pulled along control crank and swings, and drives and turns to rocker to swing accordingly, and steering link pushes or pull on deflecting roller left-right rotation, thus realizes left and right turning to.
Of the present utility model turn to the pin joint of rocker and steering link before center of rotation, it is achieved that the swaying direction of control crank is consistent with the rotation direction of deflecting roller.
This utility model simple in construction, transmission power is direct, and manipulation turns to the lightest.
Accompanying drawing explanation
Fig. 1 is this utility model structural representation,
Fig. 2 is the lateral structural representation of this utility model,
Fig. 3 is scissor aerial work platform structural representation,
Fig. 4 is steering mechanism's structural representation of tradition scissor aerial work platform.
Detailed description of the invention
This utility model is described in detail in detail with reference to the accompanying drawings.
With reference to Fig. 1,2, control crank 1 bottom of the present utility model and steering arm 2 hinge, steering arm 2 and steering spindle) it is connected with elastic cylindrical pin is fixing, turn to rocker 4 to fix with steering spindle 3 bottom and be welded into entirety, steering link 5 one end is with to turn to rocker 4 hinged, and the other end is hinged with deflecting roller 6 swing arm.
During utility model works, operating personnel is pulled along control crank 1 and swings, and drives and turns to rocker 4 to swing accordingly, and steering link 5 pushes or pull on deflecting roller 6 left-right rotation, thus realizes left and right turning to.
Of the present utility model turn to the pin joint of rocker 4 and steering link 5 before center of rotation, it is achieved that the swaying direction of control crank 1 is consistent with the rotation direction of deflecting roller 6.
This utility model simple in construction, transmission power is direct, and manipulation turns to more flexible light.
