Abstract
The utility model relates to a locking device's speed reducer is opened with running -board, including frame and worm gear lift, the worm gear lift supports in the frame, the frame is just stretched out in the lift lead screw cross -under from top to bottom of worm gear lift in the frame at the bottom of, a cross -under ratchet on the worm of worm gear lift sets up the pawl of monogamy ratchet on the worm gear lift, be equipped with the shift fork on the pawl, still is equipped with the area on the worm gear lift and replys the rotatable rocking arm that resets, corresponds the shift fork of spring, connects the wire rope upper end on the rocking arm, and the wire rope lower extreme is connected and is set up pedal in the frame.
Description
Technical field
This utility model is related to a kind of reductor, and the reductor of locking device opened by specifically a kind of pedal.
Background technology
When traditional worm and gear elevator use need be opened, shut down, manually operate on guidance panel, there is artificial operation
Reaction, time error larger, lead to worm and gear elevator can not be accurately controlled in the position of required lifting, thus impact makes
Use performance.
Content of the invention
For the deficiencies in the prior art, this utility model provides a kind of structure simply, and people can be effectively shortened in simple operation
In the response time that work operates on guidance panel, reduce operating error, that improves lifting precision controlling opens locking with pedal
The reductor of device.
The technical solution adopted in the utility model is：The reductor of locking device opened by a kind of pedal, including frame
With worm and gear elevator, in frame, the elevating screw of worm and gear elevator is from top to bottom for worm and gear elevator support
Wear be connected in frame and stretch out frame ground it is characterised in that：Wear on the worm screw of described worm and gear elevator and connect a ratchet, worm gear
The ratchet of the corresponding ratchet of setting one in worm screw elevator, ratchet is provided with shift fork, worm and gear elevator is additionally provided with one and takes back
The multiple rotatable reset of spring, the rocking arm of corresponding shift fork, connecting steel wire ropes upper end on rocking arm, steel wire rope lower end connect setting is in frame
On foot-operated.
The worm screw external handle of described worm and gear elevator.
This utility model controls rocking arm using foot-operated through steel wire rope, makes ratchet clamping or the spine that gets loose by the corresponding shift fork of rocking arm
Wheel, thus meeting the shutdown of worm and gear elevator and starting requirement, simple operation, control accuracy is high.
Brief description
Fig. 1 is this utility model structural representation.
In figure：Frame 1, elevating screw 2, worm screw 3, ratchet 4, ratchet 5, shift fork 6, rocking arm 7, steel wire rope 8, ride 9.
Specific embodiment
It is described further below in conjunction with drawings and Examples.
Shown in Fig. 1：The reductor that locking device opened by a kind of pedal includes frame 1 and worm and gear elevator, snail
Worm and gear elevator support in frame 1, from top to bottom wear and be connected in frame 1 and stretch by the elevating screw 2 of worm and gear elevator
Go out frame ground, the worm screw 3 of worm and gear elevator is worn and connects a ratchet 4, the corresponding ratchet 4 of setting one in worm and gear elevator
Ratchet 5, ratchet 5 is provided with shift fork 6, and worm and gear elevator is additionally provided with the rotatable reset of a band returning spring, corresponding shift fork 6
Rocking arm 7, connecting steel wire ropes 8 upper end on rocking arm 7, steel wire rope 8 lower end connect setting in frame foot-operated 9.
On the basis of above-described embodiment, the worm screw of worm and gear elevator also can external handle, realize manual operation lifting.
