Background
A crawler-type traveling chassis is a common rotating chassis, and the chassis is widely applied to excavators, drilling machines and cranes. Typically, the slewing chassis is such that the slewing action between the superstructure and substructure is achieved by means of inner and outer gear rings and a drive motor, and for such structures, there are typically no additional locking means; the locking action is realized only by the friction force between the driving motor and the gear ring or the torque output by the motor, so that the loads of the driving motor and the gear ring are increased, the service lives of the driving motor and the gear ring are inevitably shortened for a long time, and the locking force cannot be ensured, so that the looseness is easily generated when the upper structure acts.
Disclosure of Invention
An object of the utility model is to overcome above-mentioned defect, provide a locking mechanism of additional between superstructure, the substructure on gyration chassis, it can be effectively to implement the locking action between superstructure, the substructure and do not influence gyration ring gear or CD-ROM drive motor.
In order to achieve the above object, the present invention is realized as follows:
the locking mechanism is arranged between the upper frame and the rotating mechanism or between the upper frame and the lower frame, and the locking mechanism realizes temporary fastening connection between the upper frame and the rotating mechanism or between fixed parts on the lower frame through clamping force, so that the aim of locking between the upper frame and the lower frame is fulfilled.
The rotary mechanism comprises an inner gear ring arranged on the lower frame and an outer gear ring arranged on the upper frame.
The locking mechanism for the rotary chassis comprises clamping arms and a fixing plate, the fixing plate is arranged on the lower frame or an inner gear ring of the rotary mechanism, the clamping arms are arranged on the upper frame, and the purpose of locking between the upper frame and the lower frame is achieved through clamping force of the clamping arms on the fixing plate.
The utility model provides a locking mechanism does not do any change to the rotation mechanism on the existing equipment, does not rely on the rotation mechanism on the existing equipment yet, so to the existing equipment on, can not increase any extra burden, on the contrary, through the stationary blade that sets up on rotation mechanism and the clamp force cooperation between the arm lock that sets up on upper portion frame, can realize the locking function on the optional position between upper portion automobile body and the lower part automobile body.
On the basis, the utility model provides a further disclosure is done to the arm lock to locking mechanism, and it is a simple structure, reliable, high-efficient and easy to maintain 'clip' structure:
the arm lock includes actuating mechanism, activity chuck and fixed chuck, and wherein, the activity chuck is connected through the pivot and with upper portion frame rotation, sets up fixed chuck at the side of activity chuck, fixed chuck passes through the bolt and the snap-on is on the upper portion frame, sets up actuating mechanism between activity chuck and fixed chuck, and under actuating mechanism's effect, the activity chuck rotates around the pivot to the realization and the fixed chuck between press from both sides tightly or loosen the action.
In the clamping arm, the driving mechanism comprises a pneumatic piston or a hydraulic piston, and two ends of the piston are respectively connected with the movable chuck and the fixed chuck.
To sum up, the utility model provides a but wide application is and have the locking mechanism of characteristics such as reliable, high-efficient and easy implementation on the gyration chassis.

Detailed Description
The invention is further illustrated by the following specific examples.
A locking mechanism for a rotary chassis comprises an upper frame, a lower frame and a rotary mechanism, wherein the upper frame and the lower frame are connected through the rotary mechanism, and the upper frame and the lower frame are enabled to do rotary motion in a horizontal plane under the action of the rotary mechanism; the locking mechanism is arranged between the upper frame and the swing mechanism or between the upper frame and the lower frame, and the locking mechanism realizes temporary fastening connection between the upper frame and the swing mechanism or a fixed part on the lower frame through clamping force, so that the aim of locking the upper frame and the lower frame is fulfilled.
The locking mechanism comprises a clamping arm and a fixing piece, wherein the fixing piece is arranged on the lower frame or an inner gear ring of the rotary mechanism, the clamping arm is arranged on the upper frame, and the purpose of locking between the upper frame and the lower frame is realized through the clamping force of the clamping arm on the fixing piece; the arm lock includes actuating mechanism, activity chuck and fixed chuck, and wherein, the activity chuck through the pivot and with upper portion frame rotation connection, set up fixed chuck at the side of activity chuck, fixed chuck passes through the bolt and the snap-on is on the upper portion frame, set up pneumatic piston or hydraulic piston as actuating mechanism and be connected with activity chuck, fixed chuck respectively between activity chuck and fixed chuck, under actuating mechanism's effect, the activity chuck rotates around the pivot to the realization with fixed chuck between press from both sides tightly or relax the action.
As shown in fig. 1 and 2, the locking mechanism has the following specific embodiments:
a fixed shaft 412 of the locking structure 41 is fixedly arranged on the frame 4, a clamp 411 and a clamp 415 are coaxially assembled on the fixed shaft 412, a clamping cylinder piston rod 413 is connected with the clamp 411, a clamping cylinder barrel 414 is connected with the clamp 415, and after the clamping cylinder piston rod 413 extends, the clamp 411 and the clamp 415 clamp a steel ring 52 on the crawler chassis 5, so that the vehicle body 4 and the crawler chassis 5 are locked. After the clamping cylinder piston rod 413 is retracted, the clamp 411 and the clamp 415 release the steel ring 52 on the crawler chassis 5, and the vehicle body 4 can rotate around the crawler chassis 5 through the slewing support 51.
