It is connected to hydraulic cylinder, lower shake-changing arm has a boss；It is welded with stopping means, described stopping means are spacing by two in described frame
Mechanism Combination forms, and described position-limit mechanism includes limiting plate, and limiting plate is connected with position-arresting disk, and position-arresting disk passes through screw thread
It is connected with screw rod, described screw rod is fixed by locking nut；The center distance of described position-limit mechanism is less than the width of boss；
The top of described screw rod is connected with fixing base plate, oscillating bearing and jacking block, and described oscillating bearing passes through holding screw
It is fixed on screw tip with bearing baffle, fixed plate base plate and jacking block are threaded connection and are stuck in the both sides of oscillating bearing.
Further, it is bolted between described limiting plate and position-arresting disk.
Further, described screw rod is connected with handwheel.
Further, described handwheel is connected on screw rod, and handwheel includes the body with a through hole, connects around body
There is Handheld Division, screw rod is had one section of handwheel section being matched with hole size.
Beneficial effect using the technical solution of the utility model is：
1st, because of the characteristic of oscillating bearing, substantially can realize moment and pressure is born with larger contact surface, reduce local
Pressure, also reduces the vibration influence of equipment；
2nd, there are two jacking blocks, strengthen stability when rocking arm boss is contacted with jacking block well, avoid it well
The immense pressure that front moment point contact causes all brings serious hidden danger with shaking to the stability of equipment and safety；
3rd, the force stability of thrust articulated bearing is well a lot of compared with butterfly spring, good damping effect；
4th, installation, adjustment, maintenance, replacing are all very convenient.

Specific embodiment
Presently in connection with accompanying drawing, this utility model is described in further detail.These accompanying drawings are the schematic diagram of simplification,
Basic structure of the present utility model is only described in a schematic way, therefore it only shows the composition relevant with this utility model.
As shown in Figure 1, Figure 2 and Figure 3, a kind of stopping means of Vertical Mill, including frame 5, frame 5 are provided with bearing block 4,
On bearing block 4, upper rocker arm 3 and lower shake-changing arm 6 are connected respectively with pin by axle, upper rocker arm 3 is also associated with grinding roller 1, grinding roller 1 lower section peace
Dress mill 2, lower shake-changing arm 6 is also associated with hydraulic cylinder 8, lower shake-changing arm 6 has a boss 20；Stopping means 7 are welded with frame 5,
Stopping means 7 are combined by two position-limit mechanisms, and position-limit mechanism includes limiting plate 9, and limiting plate 9 is connected with position-arresting disk
10, position-arresting disk 10 is threaded connection screw rod 12, screw rod 12 passes through locking nut 13 to be fixed, and locking nut 13 is in screw rod 12
The position of standing screw 12 after the completion of position adjustments, and have certain locking effect；The center distance of two position-limit mechanisms is less than
The width of boss 20；The top of screw rod 12 is connected with fixing base plate 15, oscillating bearing 17 and jacking block 16, and the top of screw rod 12 connects
