Description
Technical field
The present invention relates to a kind of loop wheel machine, more particularly to a kind of slewing crane arm support rendezvous method flange aperture sealing structure.
Background technology
Loop wheel machine is the popular address of crane, is had widely in a series of heavy industry products such as ship, equipment, machinery, mould
Using.Loop wheel machine is made up of power set and support two parts.Power set are by motor, decelerator, clutch, brake, rope
The composition such as cylinder and steel wire rope.Motor is designed with the power-off i.e. mechanism of braking to be close to magnetic-type single-phase condenser motor;Motor also fills
There is thermoswitch, motor overheating can be prevented and burnt;Reductor is two-stage The gear deceleration, is fixed on motor;Clutch, brake
It is integrated with rope roll dress, but when clutch be in disengaged position, achievable rapid decrease, operational brake can control decrease speed
To avoid impacting.The circular hole that power set outer casing frontispiece is opened can be used to install hair-dryer, and user can be equipped with as needed
Hair-dryer carries out pressure cooling.The mobile jib and cursor composition that holder part is made up of screw rod, very heavy nut and vertical rod.Cursor
360 degree can be rotated on mobile jib, arm end be provided with travel switch with anti-operation failure or button failure and caused by lifted by crane position
Accident.Operation button starter realize motor positive and inverse can by wire rope roll around, decontrol, and lifted by crane by holder part pulley,
Object is transferred to complete lifting job.
At present, for slewing crane, docking generally use between its arm support be flange docking mode, it is and existing
Flange generally use be bolt directly through the connection for realizing two abutted flanges after mounting hole by nut check, and this
The type of attachment of sample can cause flange mounting hole sealing poor, the easy oxidation and rusting of bolt, and even resulting in bolt can not be from installation
Taken out in hole, influence the follow-up maintenance of arm support.
The content of the invention
The technical problem to be solved in the present invention is to provide a kind of slewing crane arm support rendezvous method flange aperture of good sealing effect
Sealing structure.
In order to solve the above technical problems, the technical scheme is that:A kind of slewing crane arm support rendezvous method flange aperture is close
Seal structure, its innovative point are:Including
The first abutted flange, the second abutted flange of a pair of mutual cooperations;
First abutted flange is distributed with circumferencial direction of the one end that the second abutted flange is in contact along the first abutted flange
There is a connection bump of several circular arrays distribution, the connection bump is by along from the first abutted flange to the second abutted flange
The cylindrical section and round platform section common combination set gradually forms, and the big one end of the round platform section bore is connected with cylindrical section, and circle
The bore at the platform section end is consistent with the bore of cylindrical section, and external thread structure is additionally provided with the surface of round platform section;
It is provided with several corresponding with connection bump on second abutted flange and holds the through hole that connection bump passes through, at first pair
Connection bump on acting flange by connecting lock nut connection through realizing the first abutted flange after the through hole on the second abutted flange
With the connection of the second abutted flange;
The connecting lock nut is a cylindrical structure, has a round platform section phase with the first abutted flange in one end of connecting lock nut
Corresponding groove, the inwall of the groove have a female thread structure being engaged with the external thread structure of round platform section.
Further, a gasket seal is additionally provided between the second abutted flange and connecting lock nut.
The advantage of the invention is that:In the present invention, by changing bolted mode between two traditional flanges,
The connected mode coordinated using connection bump, through hole and connecting lock nut three, eliminates the connection on one of abutted flange
Hole, corresponding sealing effectiveness also just improve, and by the connected mode between connecting lock nut and round platform section, reduce oxidation
The probability to get rusty, facilitate the maintenance of junior scholar.
By setting a gasket seal between the second abutted flange and connecting lock nut, between the two close is ensured that
Sealing property.
Brief description of the drawings
The present invention is further detailed explanation with reference to the accompanying drawings and detailed description.
Fig. 1 is the schematic diagram of the slewing crane arm support rendezvous method flange aperture sealing structure of the present invention.
Embodiment
The following examples can make professional and technical personnel that the present invention be more fully understood, but therefore not send out this
It is bright to be limited among described scope of embodiments.
A kind of slewing crane arm support rendezvous method flange aperture sealing structure as shown in Figure 1, including
The first abutted flange 1, the second abutted flange 2 of a pair of mutual cooperations.
In the first abutted flange 1 and circumferencial direction of the one end that the second abutted flange 2 is in contact along the first abutted flange 1
The connection bump of several circular array distributions is distributed with, the connection bump along from the first abutted flange 1 to the second by docking
The cylindrical section 3 and the common combination of round platform section 4 that flange 2 is set gradually form, and the big one end of the bore of round platform section 4 is connected with cylindrical section 3,
And the bore at the end of round platform section 4 is consistent with the bore of cylindrical section 3, external thread structure is additionally provided with the surface of round platform section 4.
It is provided with the second abutted flange 2 several corresponding with connection bump and holds the through hole 5 that connection bump passes through,
Connection bump on one abutted flange 1 by the connection of connecting lock nut 6 through realizing first after the through hole 5 on the second abutted flange 2
The connection of the abutted flange 2 of abutted flange 1 and second.
Connecting lock nut 6 is a cylindrical structure, one end of connecting lock nut 6 have one and first abutted flange 1 round platform
4 corresponding grooves 7 of section, the inwall of the groove 7 have a female thread structure being engaged with the external thread structure of round platform section 4.
A gasket seal is additionally provided between the second abutted flange 2 and connecting lock nut 6.By in the second abutted flange 2
One gasket seal is set between connecting lock nut 6, ensures that sealing property between the two.
By changing bolted mode between two traditional flanges, using connection bump, through hole 5 and connecting lock nut
The connected mode that 6 threes coordinate, eliminates the connecting hole on one of abutted flange, and corresponding sealing effectiveness is also just lifted
, and by the connected mode between connecting lock nut and round platform section, the probability of oxidation and rusting is reduced, facilitate the dimension of junior scholar
Shield.
