Abstract
The utility model relates to a two-way gyration ratchet lift strutting arrangement. The device is characterized in that a wheel frame is connected with an inner cylinder by a pin shaft, a supporting wheel is arranged in a front fork of the wheel frame, a screw is arranged in the inner cylinder, and the screw and the inner cylinder are arranged in an outer cylinder; the bearing is arranged on the screw rod and arranged on the convex ring, the upper cover is arranged at the end of the outer cylinder, and the ratchet wheel and the connecting plate are arranged on the screw rod and are pressed by the nut; the pawl is fixed on the shaft sleeve, the shaft sleeve and the rocker arm are respectively arranged on two ends of the pawl shaft, and the pawl shaft is fixed on the connecting plate. When the trailer is to be separated from the tractor, the rocker arm is lifted up and swings in a reciprocating manner within the range of 0-60 degrees, the pawl pushes the ratchet wheel to drive the screw rod to rotate, the inner cylinder descends, the supporting wheel arranged on the wheel frame is grounded, the trailer is stably supported, and the inner cylinder can rotate the supporting wheel to play a guiding role when the trailer moves. The utility model has simple structure and convenient use; the ratchet wheel can rotate in two directions, and the ascending and descending speeds of the supporting device are high; the parking and moving become light, labor and time are saved.
Description
Technical field
The utility model relates to a kind of liftable supporter, the bi-directional rotary ratchet liftable supporter that supports before specifically a kind of single-axle trailer.
Background technology
Single-axle trailer must could be realized parking, moving of trailer by bracing or strutting arrangement after breaking away from tractor truck.In the use of trailer, should have bracing or strutting arrangement and to use flexibly, to make things convenient for the characteristics requirement.This just requires bracing or strutting arrangement to have certain lifting and moves flexibly, carries out to adapt to parking with short-range manpower of trailer.Bracing or strutting arrangement should be able to have the lifting mechanism of height to satisfy trailer and park steadily when parking, and mobile trailer is flexible.
At present, the mode that the trailer support device that uses generally adopts rocking handle to drive worm drive realizes lifting, rocking arm must be around the whole circle revolution of screw axis during work; inconvenient operation when rocking arm is long; rocking arm short-term operation is got up and required great effort very much; the lifting mechanism that therefore existing bracing or strutting arrangement adopted is difficult to meet the human engineering requirement, and it is very inconvenient to use.
Summary of the invention
For overcoming the deficiency of existing bracing or strutting arrangement lifting mechanism, the invention provides a kind of bi-directional rotary ratchet liftable supporter.This installs flexible operation, light, can satisfy parking and movement requirement of trailer.
The purpose of this utility model is achieved in that
Mainly form by wheel carrier, inner core, urceolus, screw rod, ratchet, ratchet, axle sleeve, pawl axis and rocking arm.Wheel carrier is connected with bearing pin with inner core, is provided with hook on wheel carrier, is provided with one section screw thread in the endoporus of inner core, and screw rod is packed in the inner core, places in the urceolus, is provided with fixed connecting plate, geometrical clamp and stay hook on outer tube wall.Screw rod is provided with bulge loop, and bearing is contained in and places on the screw rod on the bulge loop, and loam cake is contained in the urceolus termination, and screw rod stretches out loam cake, and ratchet and connecting panel are contained on the screw rod, are compressed by nut.Ratchet is fixed on the axle sleeve, and axle sleeve and rocking arm are contained in respectively on two of pawl axis, and axle sleeve is rotatable on pawl axis, and pawl axis is fixed on the connecting panel, and ratchet is rotatable to commutate.
During use, when propping the trailer towing bar, rocking arm is lifted, rocking arm back and forth shakes in 0～60 ° of scope, ratchet promotes ratchet and drives the screw rod rotation, inner core is risen, wheel carrier is taken off, ratchet is turned over turn to another direction again, shaking the rocking arm inner core descends, be contained in the support wheel ground connection on the wheel carrier, make trailer support stable, rocking arm is regained and is stuck in the geometrical clamp; The rotatable support wheel of inner core play the guiding role when trailer moved.When removing the support of trailer towing bar, operating sequence in contrast.
The advantage that the utility model compared with prior art has is:
1. simple in structure, easy to use;
2. but adopt the structure of ratchet bi-directional rotary, the rising of bracing or strutting arrangement, step-down operation speed are fast;
The parking of trailer, move and become light, laborsaving saving time.
