Specific embodiment
It should be noted that in the absence of conflict, the features in the embodiments and the embodiments of the present application can phase
Mutually combination.The present invention will be described in detail below with reference to the accompanying drawings and embodiments.
Fig. 1-Fig. 7 is shown according to some embodiments of the present invention.
As shown in Figure 1, a kind of semi-automatic towing pin with the levelling regulatory function of bolt, comprising: support 5, control stick are total
At, second connecting rod 8, towing pin 9, wherein support 5 is mounted by means of bolts on the top of vehicle frame 16 of tractor, and towing pin 9 is inserted
It connects in the traction seat 15 of 16 tail portion of vehicle frame, control rod assembly is mounted on support 5.
Specifically, control rod assembly includes sequentially connected control stick 2, flanger bearing bush 10, first connecting rod 4 and second
Connecting rod 8,2 bottom of control stick are fixedly connected with flanger bearing bush 10, and one end of first connecting rod 4 is also fixedly connected with flanger bearing bush 10,
And first connecting rod 4 and control stick 2 are in a certain angle, wherein flanger bearing bush 10 is rotatablely connected by pin shaft and support 5；So that whole
A control rod assembly can turn an angle around the pin shaft on support 5
Wherein, the top of control stick 2 is provided with handle 1, and operator is facilitated to hold control stick 2, improves operational comfort；It turns over
The setting of side axis set 10 enables pin shaft to rotate freely and wear-resisting.The first connecting rod 4 is Z-shaped, so that operating stick is relative to driving
It sails seat and occupies side arrangement.
Specifically, the other end of the first connecting rod 4 is flexibly connected with second connecting rod 8 by pin shaft 7, split pin, traction
Pin 9 is equally flexibly connected by pin shaft 7, split pin with second connecting rod 8, and control rod assembly rotation drives second connecting rod 8 and traction
Pin 9 moves up and down, and towing pin 9 is made to pass through clearance fit with the traction seat 15 being assemblied on vehicle frame 16, reaches about 9 towing pin fortune
Dynamic effect.To which by operating mechanism, people may be implemented can take off the purpose of towing pin on seat.
In one embodiment, as shown in figure 5, the bottom front of control stick 2 is provided with limited block 11, it is arranged on limited block 11
Have leveling bolt 12, after control stick 2 turns an angle, leveling bolt 12 can resist support 5, prevent control stick 2 continue to
Lower rotation, to can control 2 control run of control stick by 12 length of leveling bolt, the raised position for reaching towing pin 9 can
Control prevents towing pin from deviating from when being promoted and can not carry out return.The leveling bolt 12 of 2 lower section of control stick can be according to practical dress
Limit height is adjusted with situation, operates smooth unobstructive effect to reach hook abjection or mounting.
In one embodiment, as shown in Figure 1, being provided with tension spring 3 on support 5, connect in the middle part of one end of tension spring 3 and control stick 2
It connects, the other end is connect with the support plate 6 on support 5, and when control stick 2 needs return, operator unclamps control stick 2, passes through drawing
The stretching action of spring 3 can pull control rod assembly back to rotate, and towing pin 9 is made to be returned to the effect of original state in time；Increase
Add tension spring 3, can be effectively prevented towing pin 9 have return not in time with return is not in place happens.
In one embodiment, as shown in Figure 1, setting limit handle 14, limit handle 14 are in L font, limit on support 5
One end of handle 14 and support 5 are rotatablely connected, and limit handle upper portion can turn on the upside of first connecting rod, when towing pin 9 is located at
When in traction seat 15, control rod assembly turns to initial position, the i.e. the smallest position of angle of first connecting rod 4 and horizontal plane, this
When, by rotary limiting handle 14, first connecting rod, the rotation of limitation control rod assembly and towing pin can be pressed in by limiting handle 14
It falls off from traction seat.
When operator needs to pull up towing pin, the unrestricted position hand of control rod assembly can just be made by only stirring limit handle
Handle limitation, and then ability manipulation bar rotation, driver's maloperation, which can be effectively prevented, causes towing pin to be deviate from, further
The safety and reliability of hoisting mechanism.
In one embodiment, as shown in fig. 7, increasing guide sleeve 13 on the top plate of traction seat 15, guide sleeve 13 and traction
Pin 9 matches, and guarantees the hole that can be aligned on traction seat 15 when 9 return of towing pin.
The course of work of the levelling regulating mechanism of bolt of the invention is as follows:
When suspension vehicle needs to be articulated in tractor chassis, the handle 1 that operator holds on control stick 2 is moved downward,
Control stick 2 rotates around support 5 and first connecting rod is driven to tilt upwards, and then second connecting rod 8 and towing pin 9 is driven up to move,
The tiger's jaw of traction seat 15 is exposed, the hook on suspension vehicle is facilitated to be inserted into traction seat 15；It is led when operator adjusts
The position for drawing vehicle, when keeping the hook for hanging vehicle opposite with the position of traction seat 15, operator unclamps again control stick 2, and control stick 2 exists
Under the stretching action of tension spring 3, towing pin 9 is made to be returned to original state in time, is inserted into traction seat 15.To realize will hook with
The effect that traction seat 15 links together.Towing pin is taken off and filled to realize that people can be operated on seat by mechanism
On.
When suspension vehicle needs to remove from tractor, i.e., hook is detached from traction seat, and operator equally holds on control stick 2
Handle 1 move downward, control stick 2 is rotated around support 5, and first connecting rod is driven to tilt upwards, and then drive 8 He of second connecting rod
Towing pin 9 up moves, and extracts towing pin 9 from the circular hole of hook out, and then deviate from hook can from traction seat；Work as extension
Hook is completed from taking off in traction seat, and operator unclamps again control stick 2, and control stick makes towing pin 9 under the stretching action of tension spring 3
It is returned to original state in time.
Compared with prior art, the present invention has the further advantage that
1, by the way that guide sleeve is arranged on the top plate of traction seat and leveling structure is arranged in control stick, control stick is rotated and is gone
Cheng Jinhang limit prevents Semi-automatic bolt promotion is not in place from causing hook abjection difficulty or excessively promotion that bolt is caused to can not be successfully
Return.By increasing returning pull-spring, realize that towing pin automatically resets.
2, by increasing limit handle on control stick, when being operated, stirring limit handle could manipulation
Bar prevents driver's maloperation from towing pin being caused to be deviate from, the safety and reliability of further hoisting mechanism.
The foregoing is only a preferred embodiment of the present invention, is not intended to restrict the invention, for the skill of this field
For art personnel, the invention may be variously modified and varied.All within the spirits and principles of the present invention, made any to repair
Change, equivalent replacement, improvement etc., should all be included in the protection scope of the present invention.
