Abstract
The invention discloses a heavy fan-shaped access door device of a torque rolling machine, which is arranged on an upper machine case and a lower machine case, wherein a wear-resisting lining plate is arranged in the upper machine case, a top loose bolt is arranged at the lower part of an access door, and an upper hoop and a lower hoop are integrated with the access door by fixed bolts and are arranged on a door hinged shaft by a fastening bolt. The fastening bolt is loosened, the top loose bolts are tightened downwards, and then the access door is lifted upwards axially on the door hinged shaft; the fastening bolt is locked, and the upper hoop and the lower hoop on the access door tightly hold the door hinged shaft; and the top loose bolts are unscrewed upwards, and the access door is suspended. Although the heavy fan-shaped access door device is large and heavy, the access door can be opened easily without hoisting equipment, and the operation is very convenient and rapid.
Description
Technical field
The invention belongs to vertical grinder access door structure, be specially a kind of fan-shaped access door device of heavy type of torch roller mill.
Background technology
Existing vertical grinder access door has the similar access doors such as individual layer light door, sandwiched door; Wherein, 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, need lifting appliance during unlatching, there is the problem that maintenance of opening the door is inconvenient.
Summary of the invention
For the deficiencies in the prior art, the invention provides a kind of fan-shaped access door device of heavy type of torch roller mill, solve the problem in above-mentioned background technology.
Technical problem solved by the invention realizes by the following technical solutions:
A kind of fan-shaped access door device of heavy type of torch roller mill, be arranged on upper case and lower case, in upper case, abrasion-proof backing block is installed, described access door bottom is provided with the loose bolt in top, upper anchor ear and lower anchor ear form an entirety by set bolt and access door, and upper anchor ear and lower anchor ear are arranged on 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 door hinge axle; Bolt is held in locking tightly, holds the upper anchor ear on access door and lower anchor ear tightly door hinge axle; Upwards unscrew the loose bolt in top, access door is hanged.
The two ends of described door hinge axle arrange upper bearing (metal) and lower bearing respectively, and the top chock of upper bearing (metal), by being above bolted on the cover of upper case, is bolted on lower case under the step of lower bearing passes through.
Compared with prior art, beneficial effect of the present invention: although the present invention's door is very heavy very large, do not need crane gear just easily can open access door, fast very convenient.
Accompanying drawing explanation
Fig. 1 is that master of the present invention looks partial sectional view.
Fig. 2 is the B-B sectional view of Fig. 1.
Fig. 3 is top view of the present invention.
In figure: on 1 cover, 2, on bolt, 3 top chocks, 4 upper bearing (metal)s, 5 door hinge axles, 6, anchor ear, 7 access doors, 8 upper cases, the 9 loose bolts in top, 10 times anchor ears, 11 lower bearings, 12 times bolts, 13 steps, 14 lower cases, 15 abrasion-proof backing blocks, 16 hold bolt, 17 set bolts tightly.
Detailed description of the invention
Reaching object to make technological means of the present invention, creation characteristic, workflow, using method and effect is easy to understand, setting forth the present invention further below.
As Figure 1-3, a kind of fan-shaped access door device of heavy type of torch roller mill, be arranged on upper case 8 and lower case 14, not only large but also thick abrasion-proof backing block 15 is installed in upper case 8, described access door 7 bottom is provided with the loose bolt 9 in top, upper anchor ear 6 and lower anchor ear 10 form an entirety by set bolt 17 and access door 7, and upper anchor ear 6 and lower anchor ear 10 are arranged on 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 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 upper bearing (metal) 4 and lower bearing 11 respectively, and the top chock 3 of upper bearing (metal) 4 is fixed on the cover 1 of upper case 8 by upper bolt 2, and the step 13 of lower bearing 11 is fixed on lower case 14 by lower bolt 12; Therefore not only bearing capacity is large for door hinge axle 5, and rotates flexibly.
Door opening process is: that first unloads heavy fan-shaped access door holds bolt 16 tightly, be rotated down the top pine bolt 9 being arranged on access door 7 bottom and arranging again a little, access door 7 is lifted top pine, and then locking holds bolt 16 tightly, by the upper anchor ear 6 on access door 7 and lower anchor ear 10 banding door hinge axle 5; Upwards unscrew the loose bolt 9 in top again, allow access door hang, then just can easily open access door 7,
More than show and describe general principle of the present invention, principal character and advantage of the present invention.The technical staff of the industry should understand; the present invention is not restricted to the described embodiments; what describe in above-described embodiment and description just illustrates principle of the present invention; without departing from the spirit and scope of the present invention; the present invention also has various changes and modifications, and these changes and improvements all fall in the claimed scope of the invention.Claimed scope of the present invention is defined by appending claims and equivalent thereof.
