Abstract
The utility model discloses a heavy type fan-shaped access door device of a mill. The heavy type fan-shaped access door device is mounted on an upper chassis and a lower chassis, a wear-resistant lining plate is mounted in the upper chassis, jack loosening bolts are arranged at the lower part of an access door, upper hoops and lower hoops are integrated with the access door through fixing bolts, and the upper hoops and the lower hoops are mounted on a door hinge shaft through embracing bolts; the access door is axially and upward lifted from the door hinge shaft through loosening the embracing bolts and downward screwing the jack loosing bolts; the upper and lower hoops on the access door are enabled to tightly embrace the door hinge shaft through locking the embracing bolts; and the access door is suspended through upward screwing the jack loosing bolts. Although the heavy type fan-shaped access door device is very heavy and large, the access door can be easily opened without hoisting equipment, so that the heavy type fan-shaped access door device is very convenient and efficient.
Description
Technical field
The utility model belongs to vertical grinder access door structure, is specially a kind of heavy fan-shaped access door device of grinding machine.
Background technology
Existing vertical grinder access door has the similar access doors such as individual layer light door, sandwiched door; Wherein, the individual layer light door is easy to open, but is not rotary unlatching; Sandwiched door not only heavily but also thick is opened and is not easy, and needs lifting appliance during unlatching, has the inconvenient problem of maintenance of opening the door.
The utility model content
For the deficiencies in the prior art, the utility model provides a kind of heavy fan-shaped access door device of grinding machine, has solved the problem in the above-mentioned background technology.
The technical problem that the utility model solves realizes by the following technical solutions:
A kind of heavy fan-shaped access door device of grinding machine, be installed on upper case and the lower case, abrasion-proof backing block is installed in the upper case, described access door bottom is provided with the loose bolt in top, upper anchor ear and lower anchor ear form an integral body by set bolt and access door, and upper anchor ear and lower anchor ear are installed on the door hinge axle by holding bolt tightly; Unclamp and hold bolt tightly, tighten the loose bolt in top downwards, access door is axially upwards lifted on the door hinge axle; Bolt is held in locking tightly, holds the upper anchor ear on the access door and lower anchor ear tightly the door hinge axle; Upwards unscrew the loose bolt in top, access door is hanged.
The two ends of described door hinge axle arrange respectively upper bearing (metal) and lower bearing, the top chock of upper bearing (metal) by on be bolted on the cover of upper case, the step of lower bearing by under be bolted on the lower case.
Compared with prior art, the beneficial effects of the utility model: although the utility model door is very heavy very large, do not need crane gear just can easily open access door, very convenient quick.
Description of drawings
Fig. 1 is that master of the present utility model looks partial sectional view.
Fig. 2 is the B-B cutaway view of Fig. 1.
Fig. 3 is top view of the present utility model.
Among the figure: anchor ear, 7 access doors, 8 upper cases, 9 push up loose bolt on bolt, 3 top chocks, 4 upper bearing (metal)s, the 5 door hinge axles, 6 on 1 cover, 2,10 times anchor ears, 11 lower bearings, 12 times bolts, 13 steps, 14 lower cases, 15 abrasion-proof backing blocks, 16 are held bolt, 17 set bolts tightly.
The specific embodiment
In order to make technological means of the present utility model, creation characteristic, workflow, using method reach purpose and effect is easy to understand, below further set forth the utility model.
As Figure 1-3, a kind of heavy fan-shaped access door device of grinding machine, be installed on upper case 8 and the lower case 14, not only large but also thick abrasion-proof backing block 15 is installed in the upper case 8, described access door 7 bottoms are provided with the loose bolt 9 in top, upper anchor ear 6 and lower anchor ear 10 form an integral body by set bolt 17 and access door 7, and upper anchor ear 6 and lower anchor ear 10 are installed on the door hinge axle 5 by holding bolt 16 tightly; Unclamp and hold bolt 16 tightly, tighten the loose bolt 9 in top downwards, access door 7 is axially upwards lifted on door hinge axle 5; Bolt 16 is held in locking tightly, holds the upper anchor ear 6 on the access door 7 and lower anchor ear 10 tightly door hinge axle 5; Upwards unscrew the loose bolt 9 in top, access door 7 is hanged.
The two ends of described door hinge axle 5 arrange respectively upper bearing (metal) 4 and lower bearing 11, and the top chock 3 of upper bearing (metal) 4 is fixed on by upper bolt 2 on the cover 1 of upper case 8, and the step 13 of lower bearing 11 is fixed on the lower case 14 by lower bolt 12; Therefore not only bearing capacity is large for door hinge axle 5, and rotates flexibly.
The process of opening the door is: the fastening bolt that unloads first heavy fan-shaped access door, be rotated down a little again and be arranged on the top pine bolt 9 that access door 7 bottoms arrange, access door 7 is lifted the top pine, and then bolt 16 is held in locking tightly, with the upper anchor ear 6 on the access door 7 and lower anchor ear 10 banding door hinge axles 5; Upwards unscrew again the loose bolt 9 in top, allow access door hang, then just can easily open access door 7.
More than show and described basic principle of the present utility model, principal character and advantage of the present utility model.The technical staff of the industry should understand; the utility model is not restricted to the described embodiments; that describes in above-described embodiment and the specification just illustrates principle of the present utility model; under the prerequisite that does not break away from the utility model spirit and scope; the utility model also has various changes and modifications, and these changes and improvements all fall in claimed the utility model scope.Claimed scope of the present utility model is defined by appending claims and equivalent thereof.
