Abstract
The application discloses a travelling crane fastener which comprises a gear stator, an oil cylinder, and a spring set, wherein a plurality of tooth spaces are arranged on one side of the gear stator, a fixing screw is arranged in the center of the gear stator, an outer tube is arranged on the oil cylinder, the outer tube is internally provided with a main shaft core and a piston, a piston sleeve is arranged on the outer side of the main shaft core, a cylinder cover is arranged on an opening of the outer tube, the main shaft core penetrates into the center of the gear stator after penetrating through the cylinder cover, and is combined with the fixing screw, the spring set is provided with an inner spring and an outer spring, the outer spring is arranged on the outer side of the inner spring in a penetrating manner, the spring set is arranged in the outer tube and sleeved on the outer side of the main shaft core. Therefore, the brake effect is good, an accident caused by the shaking of a crane jib during travelling can be avoided, and the safety is high.
Description
Technical field
The present invention relates to the lock of driving a vehicle, relate in particular to a kind of column of movable crane and driving lock of arm of being applicable to.
Background technology
Traditional arm fixed sturcture utilizes hydraulic motor to drive and makes screw rod gear driven miniature gears, drive big gear wheel by miniature gears again, cause braking, such braking effect can be because contact be many, so allow arm still can cause safe effect bad by double swerve under steam.
Summary of the invention
The object of the invention is to be to provide a kind of driving lock, good braking effect, can avoid arm to rock under steam and cause accident, safe.
According to an aspect of the present invention, provide a kind of driving lock, comprise gear fixed plate, oil hydraulic cylinder and spring assembly, gear fixed plate one side is provided with plural teeth groove, and central authorities are provided with check screw; Oil hydraulic cylinder has outer tube, and this outer tube inside is provided with main core and piston, and piston bush is located at main core outside, and the opening part of outer tube is provided with cylinder cap, and this main core penetrates the central authorities of gear fixed plate after passing this cylinder cap, and is combined with check screw; Spring assembly has inner spring and outer spring, and this outer spring is located in this interior bullet spring outside, and spring assembly is arranged at the inside of outer tube, and is set in main core outside.
In some embodiments: gear fixed plate is square block structure.
In some embodiments: between the opening of outer tube and cylinder cap, be also provided with pad.
In some embodiments: the outer tube side of oil hydraulic cylinder is provided with oil inlet port.
The present invention is simple in structure, easy to use, and good braking effect can be avoided arm to rock under steam and cause accident, safe.
Accompanying drawing explanation
Fig. 1 is the structural representation of a kind of lock of driving a vehicle of the present invention.
The specific embodiment
Below in conjunction with accompanying drawing explanation, the present invention is described in further detail.
As shown in Figure 1, a kind of driving lock, comprises gear fixed plate 11, oil hydraulic cylinder 12 and spring assembly 13.Gear fixed plate 11 1 sides are provided with plural teeth groove 111, and central authorities are provided with check screw 112.Oil hydraulic cylinder 12 has outer tube 121, outer tube 121 inside are provided with main core 122 and piston 123, piston 123 is sheathed on main core 122 outsides, the opening part of outer tube 121 is provided with cylinder cap 124, main core 122 passes the central authorities that penetrate gear fixed plate 11 after cylinder cap 124, and with check screw 112 combinations, with pinion fixed plate 11 be 360 degree rotate.Spring assembly 13 has inner spring 131 and outer spring 132.Outer spring 132 is located in inner spring 131 outsides, and spring assembly 13 is arranged at the inside of outer tube 121, and is set in main core 122 outsides.
Gear fixed plate 11 is square block structure, between the opening of outer tube 121 and cylinder cap 124, is further provided with pad 125.The side of the outer tube 121 of oil hydraulic cylinder 12 is provided with oil inlet port 1211.
When assembling, inner spring 131, outer spring 132, piston 123 and cylinder cap 124 are sequentially located in outer tube 121, the top of cylinder cap 124 protrudes from outside outer tube 121,122 of main cores penetrate the central authorities of cylinder cap 124, piston 123, outer spring 132 and inner spring 131, and be positioned at outer tube 121, and the front end of main core 122 stretches out outside outer tube 121, and be placed through gear fixed plate 11, and be locked on check screw 112, overall assembling can be completed.
In sum, the present invention is simple in structure, easy to use, and good braking effect can be avoided arm to rock under steam and cause accident, safe.
The above is only one embodiment of the present invention; it should be pointed out that to those skilled in the art, without departing from the concept of the premise of the invention; can also make some similar distortion and improvement, within these also should be considered as protection scope of the present invention.
