Abstract
The utility model relates to a mounting and dismounting grinding head device of a grinding mill, particularly a fluid single-cylinder rocking-bar type self-mounting-dismounting grinding head device. The utility model comprises a connecting bar, wherein one end of the connecting bar is hinged with the upper end of a rocking bar; the lower end of the rocking bar is hinged with the outer end of a piston of an oil cylinder; ear rings at the bottom of the oil cylinder are hinged with the outer end of a base; the center of the rocking bar is provided with a middle hole, and the rocking bar is also provided with a pin hole. When the grinding head needs mounting and dismounting, a rocking-bar mechanism driven by a single oil cylinder is mounted on the side surface of a rocking arm of a host machine; the rocking-bar mechanism using a hydraulic station of the grinding mill self as a power source makes the grinding head and the rocking arm respectively rotate according to the order of own rotating shafts through operating a direction valve and realizes the semi-automation of the grinding head entering and exiting the inner part of a machine shell; the whole mechanism is composed of a plurality of rod elements. The utility model has the advantages of simple structure and safe mounting and dismounting of the grinding head.
Description
Technical field
The utility model relates in the abrasive dust machinery a kind of from loading and unloading grinding head device, the especially bistrique of novel hydraulic-control vertical disc roller mill loading and unloading.
Background technology
The bistrique of all kinds of vertical disc grinding machines does not wait from the 500kg-1000kg that weighs, and the emery wheel on the bistrique is consumable accessory, and whole bistrique needs often to safeguard loading and unloading.Mostly be at present manually and finish handling operation by common hoisting machinery (as bottle gouard moved by hands, crane).Because condition restriction such as structure, weight, space, manual method are taken a lot of work, time-consuming, effort, efficient is low and potential safety hazard is bigger, machinery or personal injury often occur.
The utility model content
The utility model purpose is to provide a kind of can increase work efficiency, more safe and reliable hydraulic control single cylinder rocker-type loads and unloads grinding head device certainly.
To achieve these goals, the utility model adopts following technical scheme: a kind of hydraulic control single cylinder rocker-type is from loading and unloading grinding head device, comprise connecting rod, connecting rod one end and rocking bar upper end are hinged, the piston outer end of rocking bar lower end and oil cylinder is hinged, oil cylinder bottom earrings and base outer end are hinged, and rocking bar central authorities are provided with mesopore, also are provided with pin-and-hole on the rocking bar.
Described base outer end, middle part are hinged with support bar respectively, being hinged in addition of above-mentioned two support bars.
Described base is inner and flour mill is hinged, and the outer end is by the adjustment screw support fixation.
When needing the mounting or dismounting bistrique, in grinding machine rocking arm side, by the grinding machine body endplay device by hydraulic oil cylinder driving is installed, this mechanism utilizes the Hydraulic Station of grinding machine itself as power, reasonably cooperate by several rod members, can make bistrique automatic displacement in order, and pass in and out engine housing with the rocking arm that rotates, realize one the semi-automation of bistrique cargo handling process.
Effect of the present utility model is: during bistrique, need not join hoisting machinery in mounting or dismounting in addition,, can finish disassemble and assemble work easily as long as install this device, have simple and reliable, efficient is high, alleviate labor strength, characteristics that cost is low.

The specific embodiment
Embodiment: the hydraulic control single cylinder rocker-type shown in Fig. 1-4 is from loading and unloading grinding head device, this device is installed in flour mill rocking arm 14 outsides, pin on connecting rod 2 one ends and the bistrique 17 is 1 hinged, the other end and rocking bar 4 upper ends are hinged, piston rod 15 in rocking bar 4 lower ends and the piston cylinder is hinged, 8 end of piston cylinder earrings and base 9 outer ends are hinged, rocking bar 4 central authorities are provided with mesopore and cooperate with axis 5 on being fixed in rocking arm 14, also be provided with on the rocking bar 4 can with the pin-and-hole of rocking arm 14 pin joints.
Dismounting bistrique job order: extract the taper pin on the bistrique 17, operating hydraulically operated station hand-operated direction valve makes piston rod 15 overhanging, rocking bar 4 rotates around axis 5, connecting rod 2 pulling bistriques 17 rotate 50 degree around the bistrique rotating shaft, then realizing the affixed of rocking bars 4 and rocking arm 14 in the pin-and-hole 16 of pin 6 insertion rocking bars 4, unclamp the gap adjustment nut, the hand-operated direction valve commutation, the drive rocking bar 4 that contracts in the piston rod 15 is drawn out to removed position to bistrique 17 together with rocking arm 14 in body.After changing bistrique 17, the reversing valve operated piston rod 15 that makes is overhanging, together with rocking arm 14 bistrique 17 is pushed body, the gap adjustment of screwing on nut, pin 6 is extracted, reversing valve operated making in the piston rod 15 contracted, and rocking bar 4 rotates and by connecting rod 2 bistrique 17 returned back to the abrasive dust operating position, loads onto the bistrique taper pin and promptly finishes whole disassemble and assemble works.
Claims (3)
