Description
Technical Field
The utility model relates to a mining machinery equipment technical field, concretely relates to a structure that is used for locking adjustment sleeve to circular cone machine.
Background
The cone machine is widely used mining equipment, and a locking mechanism is generally arranged in the cone machine and used for locking the adjusting sleeve when the cone machine is screwed with the adjusting sleeve, so that the adjusting sleeve is prevented from rotating and loosening due to vibration when the cone machine works. The circular cone machine locking device who uses in the existing market generally is 6 external locking cylinders, and its theory of operation is: the locking cylinder is pressurized and loosened, decompressed and locked. In the absence of pressure, the locking cylinder is locked upwards, so that the adjusting sleeve and the support sleeve are screwed to one another. The locking cylinder is pressurized by manually operating an operating rod of the hydraulic station of the locking cylinder, and the locking pull rod slowly moves downwards after being pressurized. Because the locking cylinder is fixed with the adjusting cap through the bolt and is fixed with the adjusting sleeve through the locking cylinder pull rod and the nut, the locking pull rod moves downwards to drive the threads of the adjusting sleeve and the threads of the supporting sleeve to be loosened. The structure has the defect that the external locking cylinder is easily abraded or smashed by stones splashed from the outside in the using process, so that the dust protection of the shell of the locking cylinder is damaged, and the locking cylinder is damaged.
SUMMERY OF THE UTILITY MODEL
The to-be-solved technical problem of the utility model is to prior art's defect, provide a circular cone machine built-in locking structure who realizes that simple structure, protecting effect are good, locking jar device are difficult for impaired adoption locking jar device.
In order to solve the technical problem, the utility model adopts the following technical scheme: the utility model provides an adopt built-in locking structure of circular cone machine of locking jar device, including the host computer body, support cover, locking jar device, adjustment cover and roll mortar wall, support the cover and install on the host computer body, the adjustment cover with support set threaded connection, roll mortar wall and adjustment cover and be connected fixedly, its characterized in that: a locking ring is arranged above the supporting sleeve, the inner ring wall of the locking ring is provided with a thread matched with the external thread of the adjusting sleeve, and the locking ring surrounds the outer side of the thread part of the adjusting sleeve; a plurality of locking cylinder devices are fixed on the locking ring, locking mandrils of the locking cylinder devices extend downwards to support the supporting sleeve, and when the locking cylinder devices are in a pressure relief state, the threads of the locking ring and the threads of the adjusting sleeve are staggered by a distance and are not meshed under the use of gravity; the locking cylinder device is connected to the hydraulic station through an oil pipe, and the locking cylinder device is used for jacking the locking ring through pressurization, so that the threads of the locking ring are meshed with the threads of the adjusting sleeve, and a locking structure for adjusting the sleeve is formed.
Furthermore, a plurality of mounting holes are formed in the locking ring, the locking cylinder devices are embedded in the mounting holes and are transversely screwed into the locking ring from the outer side surface of the locking ring through screws to be connected and fixed with the locking cylinder devices, and the locking ejector rods of the locking cylinder devices just extend downwards to abut against the outwards extending circular ring platform of the supporting sleeve.
Furthermore, the top end of the adjusting sleeve is provided with a fixing ring which extends outwards, an adjusting cap is fixed on the fixing ring through a bolt, and the adjusting cap covers the locking cylinder device and the locking ring, so that the protection effect is better.
Preferably, there are 6-12 locking cylinder devices, for example 12, arranged on the locking ring along the same circumference, each locking cylinder device being vertically mounted and evenly distributed.
The hydraulic station of the locking cylinder pressurizes the locking cylinder to enable the locking ejector rod of the locking cylinder device to jack downwards and drive the locking ring to jack upwards, so that the thread pitch between the threads of the locking ring and the threads of the supporting sleeve changes, the threads of the locking ring and the threads of the adjusting sleeve are meshed and locked with each other, and the locking effect of the adjusting sleeve is achieved.
The utility model discloses easy bad to the external locking jar among the former locking structure of circular cone machine, and dustproof not good scheduling problem of effect, improve to built-in locking jar and locking ring cooperation, by the screw thread locking of locking jar jack-up locking ring and adjustment cover, not only can make the locking jar be difficult for pounding by a crashing object like this, the protection is better with dustproof effect, and it is more convenient that the adjustment cover is dismantled moreover to can improve the efficiency of production, maintenance, save cost of maintenance greatly.
