Abstract
The invention discloses a lifting device for a furnace door service vehicle operation room and relates to furnace door service vehicles for coking plants. The technical problems that ball screw connection end sockets of existing lifting devices for furnace door service vehicle operation rooms are prone to rupture and gear motors of the existing lifting devices vibrate seriously are solved. The lifting device is characterized in that an output shaft of a gear motor is connected with the end socket of a ball screw through an elastic pin coupling; a rubber adjusting pad is additionally arranged between the gear motor and a reduction gear support; and the reduction gear support is welded to a cab base. The lifting device is used for the furnace door service vehicle using motor drive to achieve ascending and descending of the operation room and has the advantages that the lifting device is simple in structure and convenient to mount, the service life of the ball screw is long, and the operation stability of the furnace door service vehicle is good.
Description
Technical field
The present invention relates to the fire door servicer that coke-oven plant uses, particularly relate to the lifting dress of a kind of fire door servicer operating room
Put.
Background technology
At present, the fire door servicer that each coke-oven plant uses drives the in the majority of ball-screw with reducing motor.Reducing motor is
Hollow shaft structure, is inserted directly into reducing motor by the connection end of ball-screw, utilizes keying fixed, and this structure makes ball wire
Thick stick has three fixing points, for redundant structure when installing.The error of perpendicularity installed due to ball-screw so that ball-screw is even
Connect termination and produce bigger stress concentration with reducing motor hollow axle, cause connection end easy fracture；During in-site installation, owing to subtracting
The concentricity at speed motor hollow axle center and ball-screw center it cannot be guaranteed that, cause reducing motor to run vibrations ratio more serious.
Summary of the invention
It is an object of the invention to overcome the shortcoming of prior art, it is provided that the lifting dress of a kind of fire door servicer operating room
Putting, the ball-screw connection end easy fracture and the reducing motor vibrations that solve existing fire door servicer operating room lowering or hoisting gear are serious
Technical problem.
The present invention is achieved by the following technical solutions:
A kind of lowering or hoisting gear of fire door servicer operating room, including: reducing motor, the reducing motor ball wire driven
Thick stick, described ball-screw one end is fixed in upper support, and the other end is fixed in lower support, and described ball-screw is by upper
Ball-screw nut and lower ball-screw nut are separately fixed in the upper lower wall panels of operating room, and described upper support is welded on steel
On structure girder, described lower support is fixed on drivers' cab base；It is characterized in that: the output shaft of described reducing motor passes through
Elastic dowel pin shaft coupling links together with the termination of described ball-screw；Set up between described reducing motor and reductor bearing
Rubber adjusting pad, described reductor bearing is welded on described drivers' cab base.
The present invention compared with prior art, owing to utilizing elastic dowel pin shaft coupling to be connected to ball-screw by reducing motor
Together, elastic dowel pin shaft coupling have certain radially, axially, angular displacement compensation dosage and shock-absorbing capacity, effectively reduce rolling
The stress of ballscrew connection end is concentrated, thus the problem solving connection end easy fracture；Due at reducing motor and motor
Add rubber adjusting pad between support, reduce the vibrations of reducing motor, it is ensured that the even running of lowering or hoisting gear.
The present invention realizes the fire door servicer of operating room oscilaltion for utilizing motor to drive, and has simple in construction, peace
Dress is convenient, and ball-screw is long for service life, the advantage of fire door servicer good operation stability.
Accompanying drawing explanation
Fig. 1 is the structural representation (front view) of the present invention；
Fig. 2 is the mounting means schematic diagram of the present invention.
Detailed description of the invention
Below in conjunction with accompanying drawing, technical scheme is clearly and completely described, it is clear that described enforcement
Example is only a present invention part, and based on the embodiment in the present invention, those of ordinary skill in the art are not making creativeness
Other embodiments obtained under work premise, broadly fall into scope.
As shown in Figure 1, 2, the lowering or hoisting gear of a kind of fire door servicer operating room, including: reducing motor 1, by reducing motor 1
The ball-screw 3 driven, described ball-screw 3 one end is fixed in upper support 5, and the other end is fixed in lower support 6, institute
State ball-screw 3 and be separately fixed at the upper lower wall panels of operating room 12 by upper ball-screw nut 4 and lower ball-screw nut 8
On, described upper support 5 is welded on steel construction girder 10, and described lower support 6 is fixed on drivers' cab base 11；Described subtract
The output shaft of speed motor 1 is linked together by the termination of elastic dowel pin shaft coupling 2 with described ball-screw 3；The described electricity that slows down
Setting up rubber adjusting pad 9 between machine 1 and reductor bearing 7, described reductor bearing 7 is welded on described drivers' cab base 15.
Reducing motor 1 drives the positive and negative rotation of ball-screw 3 by elastic dowel pin shaft coupling 2, is fixed on operating room 12
Upper ball-screw nut 4 and lower ball-screw nut 8 move up and down along the rotation direction of ball-screw 3, thus realize operating room 12
Lifting, meet the use requirement of operator.
The present invention can be embodied as the spirit without deviating from invention or essence in a variety of forms, it should therefore be appreciated that on
State embodiment and be not limited to aforesaid details, and should explain widely in claim limited range, therefore fall into right
Change and remodeling in requirement or its equivalent scope all should be claim and contained.
