Description
[ technical field ] A method for producing a semiconductor device
The utility model relates to an elasticity locking device of dolly combination formula chain block, dolly combination formula chain block are used for lifting by crane wind power generation equipment's lifting device belongs to dolly combination formula chain block's locking stop part technical field.
[ background of the invention ]
After the hoisting operation of the wind power generation equipment is finished, the trolley combined type ring chain hoist positioned in the fan cabin needs to be stopped and positioned at a fixed position to prevent the ring chain hoist from shaking.
The existing thread jacking device of the trolley combined type ring chain hoist comprises a locking block, a rubber block fixed on the top surface of the locking block and a locking rod in threaded connection with a connecting frame, wherein the locking rod extends out of the upper end of the connecting frame and is fixedly connected with the locking block, and the rubber block corresponds to the bottom surface of a track beam.
During locking operation, the locking rod is rotated clockwise to move upwards relative to the connecting frame, so that the rubber block is pushed to the bottom surface of the track beam, and the connecting frame, the trolley fixed on the connecting frame and the chain block fixed on the connecting frame are stopped at the bottom of the track beam together; when the locking is required to be released, the locking rod is rotated anticlockwise to move downwards relative to the connecting frame, so that the rubber block can be separated from the bottom surface of the track beam instantly, and the trolley device can restore to slide on the track beam.
Because the existing screw thread jacking device only depends on a locking mechanism of screw thread jacking force, once the screw thread is loosened, the locking is easy to lose efficacy, and after a gap is formed between the rubber block and the bottom surface of the track beam, the trolley combined type chain hoist is not still, so that the existing screw thread jacking device is necessary to be improved.
[ Utility model ] content
The utility model aims at providing an elasticity locking device of dolly combination formula ring chain calabash, this elasticity locking device's locking is fixed reliable, has overcome the screw thread that prior art screw thread top tight device exists and has easily become flexible the not enough of inefficacy.
Therefore, the utility model adopts the following technical scheme:
an elastic locking device of a trolley combined type ring chain hoist comprises a guide chain fixing frame, a bearing frame fixed at the upper end of the guide chain fixing frame and a locking rod in threaded connection with the guide chain fixing frame, wherein the bearing frame is provided with a vertical shaft, the upper end of the vertical shaft is sleeved with a locking block, and the top of the locking block is fixed with a rubber block; when the locking rod moves downwards, the locking block drives the rubber block to be pressed against the bottom surface of the track beam under the action of the restoring force of the compression spring.
The lever piece is connected with the guide chain fixing frame through the supporting shaft and the horizontal bushing.
The locking rod is fixed at the bottom end of the locking rod, so that the locking rod can rotate to apply force to the locking rod.
The utility model has the advantages of as follows and positive effect:
the locking device is locked on the bottom surface of the track beam by means of the elasticity of the compression spring, locking and stopping are stable and reliable, and the phenomenon that the trolley combined type chain hoist in a non-use state slides on the track beam to impact the wind power equipment due to the mechanical vibration of the wind power equipment and high altitude and high wind power and the adverse effect is generated on the trolley combined type chain hoist due to the mechanical vibration and the wind power vibration is avoided. The tight device in screw thread top with current structure relies on the check lock lever to rotate for the screw thread of link and drives the block rubber and contradict track roof beam and compare, has overcome the tight power in screw thread top and has easily been lost efficacy because of the screw thread is not hard up not enough.
