Abstract
The utility model relates to the technical fields of removal and installation of coalmine under pit crusher hammerhead, which is a crusher hammerhead hydraulic removal device. Coalmine under pit crusher hammerhead often uses the way of over fit between hammerhead and hammer, but it is very difficult during removal and installation. The utility model uses hydraulic force of coalmine under pit pump station, and the removal device comprises single flexible double function hydraulic cylinder and connection part. The connection part comprises a upper thread sleeve, a connection rod, a fixing shaft, a rotary thread sleeve, a pivot, a split pit, a flat joint, a thread joint, a lengthening rod and the lower thread sleeve; the upper thread sleeve of the connection part and the cylinder tube of the hydraulic cylinder are connected, the lower thread sleeve and the rotary thread sleeve are connected, the connection part is fixed on the hammer by the rotary thread sleeve, the hammerhead is removed and installed by stretching and retracting piston rod of the hydraulic cylinder. The utility model is suitable for removing and installing crusher hammerhead at coalmine under pit.
Description
Affiliated technical field
What the utility model related to grinder hammerhead under the coal mine removes and installs technical field, specifically a kind of grinder hammerhead hydraulic dismounting device.
Background technology
Grinder hammerhead requires to install firmly under the coal mine, does not allow to become flexible and come off under the effect of long-term intense impact counter-force, requires simultaneously can easier dismantle in the subsurface environment of colliery, change and install.In order to satisfy working condition requirement, adopt the mode of tup and hammer body interference fit to solve usually.In the subsurface environment of colliery, remove and install very problem such as difficulty with regard to having brought like this.
Summary of the invention
The purpose of this utility model provides a kind of grinder hammerhead hydraulic dismounting device, and this device can adapt to narrow rugged environment under the coal mine, utilizes the hydraulic coupling of pumping plant under the coal mine, can dismantle easily, replacing and breaker mounting tup.
The technical solution of the utility model is: adopt the list double acting hydraulic cylinder that stretches, a coupling assembly is arranged below this hydraulic cylinder, and coupling assembly is made up of last thread bush, connecting rod, fixed axis, rotation thread bush, bearing pin, split pin, plain adapter, nipple, extension bar and following thread bush; The cylinder barrel that coupling assembly is used thread bush and hydraulic cylinder links, and fixed axis stretches out perpendicular to the hydraulic cylinder axis direction and to both sides, and following thread bush and rotation thread bush link, and the rotation thread bush is used for coupling assembly is fixed on the hammer body; Fixed axis and last thread bush, down thread bush is welded into an integral body, links by both sides connecting rod and split pin and bearing pin, constitutes a rectangular frame; Connecting rod can slide on bearing pin and fixed axis, and to several stations should be arranged; One end and the hydraulic cylinder piston rod of extension bar link with screw thread, and the other end of extension bar 10 links with plain adapter 8 or nipple 9 usefulness screw threads respectively when dismounting or installation tup.
The beneficial effects of the utility model are: made full use of the condition that supplies to have hydraulic coupling under the coal mine, compact conformation adapts to narrow rugged environment under the coal mine.Having solved because of cooperating tightly makes grinder hammerhead remove and install the very problem of difficulty in the subsurface environment of colliery.

The specific embodiment
Adopt the list double acting hydraulic cylinder that stretches, a coupling assembly is arranged below this hydraulic cylinder, and coupling assembly is made up of last thread bush 2, connecting rod 3, fixed axis 4, rotation thread bush 5, bearing pin 6 split pins 7, plain adapter 8, nipple 9, extension bar 10 and following thread bush 11; The cylinder barrel that coupling assembly is used thread bush 2 and hydraulic cylinder 1 links, and fixed axis 4 stretches out perpendicular to the hydraulic cylinder axis direction and to both sides, and following thread bush 11 and rotation thread bush 5 link, and rotation thread bush 5 is used for coupling assembly is fixed on the hammer body 12; Fixed axis 4 is welded into an integral body with last thread bush 2, following thread bush 11, links with bearing pin 6 by both sides connecting rod 3 and split pin 7, constitutes a rectangular frame; Connecting rod 3 can slide on bearing pin 6 and fixed axis 4, and to 4 stations should be arranged, to satisfy the tup at dismounting diverse location place.One end and the hydraulic cylinder piston rod of extension bar 10 link with screw thread, and the other end of extension bar 10 and plain adapter 8 or nipple 9 usefulness screw threads link, and be respectively applied for the dismounting tup and tup is installed.
During use, concrete operations are as follows:
Fixedly attaching/detaching apparatus to hammer body
At first dismantle relevant bolt, pressing plate of fixed hammer etc.
Attaching/detaching apparatus is enclosed within the hammer body top of desire dismounting tup, adjust the position of slide link 3, make it be close to the hammer body both sides, allow bearing pin 6 enter in the groove of hammer body, following thread bush 11 is put on the platform on hammer body top, rotation thread bush 5 promotes attaching/detaching apparatus gradually, is securely locked on the hammer body up to attaching/detaching apparatus.
2. dismounting tup
3. installation tup
Keep the piston rod of hydraulic cylinder to stretch out state, plain adapter 8 is laid down, change nipple 9, tup 13 is installed on the nipple, slowly regain the piston rod of hydraulic cylinder, just tup 13 tractions can be advanced the installing hole of hammer body 12.Finish the installation of tup.
