Description
Technical field
The utility model technical field of engineering machinery more particularly to engineering mechanical instruments platform.
Background technique
For the engineering machinery in construction project, such as: loop wheel machine, excavator, piling machine, instrument desk view manipulation use
The needs of situation, must adjustment height or angle.The prior art uses the adjustment of instrument desk and relies on spiral shell in steering column middle position
The mode of line locking is fastened and fixed, and mechanism arrangement is complicated, and to material performance requirement height, machining accuracy requirement is high, and zero
Fatigue deformation easily occurs for component, and therefore, after long-time use, retaining mechanism effect is easy to fail.And it can not be when locking
Any angle and position are lockked, and can only be lockked in fixed angles and positions, very inconvenient.
Utility model content
The purpose of this utility model is that providing one to solve the deficiency of prior art described above instrument desk steering column
Kind engineering mechanical instruments platform steering column, steering operation is convenient, and locking effect is good.
The purpose of this utility model is realized by following technical solution: a kind of engineering mechanical instruments platform steering
Column, including pedestal, steering column are provided with outer stationary plates on the two sides of pedestal, shaft are fixed on outer stationary plates, steering column passes through
Shaft is connect with outer stationary plates, be provided on pedestal it is foot-operated, it is foot-operated on pedal spindle is installed, reset is provided on pedal spindle and is turned round
Spring, is fixed with cam on pedal spindle, the big end of cam driven driving lever, is equipped with shift lever axis on driving lever, shift lever axis is fixed on interior solid
On fixed board, by gas spring release valve rod compression, gas spring discharges valve rod and connects gas spring the small end of driving lever.
The utility model engineering mechanical instruments platform steering column, design science, rationally, simple structure, instrument desk is easy to adjust,
It is reliable and secure convenient for operating with, long service life.
The present invention will be further described with reference to the accompanying drawings and examples, the purpose of this utility model, advantage and spy
Point is explained by the non-limitative illustration of following preferred embodiments.
Detailed description of the invention
Fig. 1 is the utility model engineering mechanical instruments platform steering column schematic diagram one.
Fig. 2 is the utility model engineering mechanical instruments platform steering column schematic diagram two.
Fig. 3 is the utility model engineering mechanical instruments platform steering column schematic diagram three.
Specific embodiment
As shown in Figure 1, 2, 3, a kind of engineering mechanical instruments platform steering column, including pedestal 11, steering column 9, the two of pedestal 11
It is provided with outer stationary plates 12 on side, shaft 10 is fixed on outer stationary plates 12, steering column 9 is connected by shaft 10 and outer stationary plates 12
It connects, foot-operated 1 is provided on pedestal 11, pedal spindle 2 is installed on foot-operated 1, reduction torsion spring 4, pedal spindle 2 are provided on pedal spindle 2
On be fixed with cam 3, cam 3 drives the big end of driving lever 5, is equipped with shift lever axis 6 on driving lever 5, shift lever axis 6 is fixed on internal fixation plate
On 13, the small end of driving lever 5 compresses gas spring release valve rod 7, and gas spring discharges valve rod 7 and connects gas spring 8.
At work, driver is pressed down with right crus of diaphragm by foot-operated 1 staff, and foot-operated 1 drives pedal spindle 2 and is mounted on foot
The cam 3 stepped on axis 2 rotates clockwise together, and cam 3 pushes 5 big end of driving lever in rotary course, makes driving lever 5 around driving lever
Axis 6 rotates counterclockwise, and 5 small end of driving lever compresses gas spring release valve rod 7, to open 8 lock valve of gas spring, driver at this time
Steering column 9 can be pushed to carry out swing angle, when steering column 9 is pushed to it by driver operates comfortable position, unclamped
Right crus of diaphragm, when the reduction torsion spring 4 on pedal spindle 2 resets, band moving cam 3 and foot-operated 1 revolution, driving lever 5 lose the pressure of cam 3, dial
The power that 5 small end of bar acts on gas spring release valve rod 7 is eliminated, and gas spring discharges reset spring of the valve rod 7 inside gas spring 8 and makees
With lower reset, to lock gas spring 8, steering column 9 can not be swung, so that steering column be locked.
The steering column breaks previous steering column locking mode and relies on the mode of screw-threaded coupling in steering column middle position, and changes
For bottom adjusting, the working method locked by the coupling mechanism force of gas spring.It can be locked in fixed angles and positions when locking
Firmly, very convenient.
The above-mentioned embodiment enumerated is only to the utility model illustration, is not to limit made by the utility model
It is fixed.The utility model can also be implemented using other way, herein not redundant one by one.In every case equivalent replacement or equivalent is used
The technical solution formed is converted, the protection scope of the requires of the utility model is belonged to.
