Description
Technical field
The invention belongs to the building machinery field, be specifically related to can be applicable to the haulage cable equalizing structure that coliseum opens and closes roofing.
Background technology
The roofing of the coliseum of open and close type adopts rope traction to drag.Its roofing is spherical, and the walking track that adapts with it is an arch, thereby in roofing switching process, the deflection angle of haulage cable may all can change in all directions.Two pull of steel wire can be different inequality because of deflection angle, the pulling force difference, the roofing that wire rope drags just can not parallelly move, be on the arch track because of roofing again, uneven move is easy to cause that roofing is stuck on a certain orbital position, can't finish switching, even may cause associated mechanisms, such as the damage of wire rope, walking carriage etc.So require comprehensive balancer of wire rope of haulage cable design of roofing for this reason, make wire rope in distraction procedure, the angle of whichever direction changes, and can both keep stress equalization at any time, makes roofing parallel mobile, opens and closes normal.
Summary of the invention
The object of the present invention is to provide a kind ofly can according to circumstances change self-reacting mechanical device, can keep the comprehensive stress equalization of haulage cable constantly.
For reaching above purpose, solution of the present invention is:
A kind of comprehensive balancer that can be used for haulage cable, comprise bearing, connection bearing, switching guide, balance arm, cable wire enclosed socket, first bearing pin, second bearing pin, axis plate, connecting bearing is positioned on the bearing, its bearing is installed on the corresponding mechanism, connects between bearing and the balance arm to be connected by the guide of transferring.
Further: this switching guide is provided with two orthogonal but disjoint pin shaft holes, with two bearing pins other members that are connected, the pin shaft hole of its top and first bearing pin be connected the switching guide be connected bearing, the pin shaft hole that it is following and second bearing pin guide and the balance arm of transferring that be connected.
This connection bearing is provided with pin-and-hole and passes for first bearing pin.
The both sides of this balance arm can be connected with two cable wire enclosed sockets that are connected with wire rope by the mode symmetry of bearing pin or ball pivot.
This connection bearing and bearing pass through bolt.
Hinged between this first bearing pin and the switching guide by oscillating bearing.
The oscillating bearing both sides are carried out axial location with circlip for hole on the connection bearing.
This first bearing pin is provided with oilhole, and the straight forced filling oil cup is installed on it.
This bearing pin can be common bearing pin, also can be that lineoutofservice signal pull is measured pin.
The end of this first bearing pin, second bearing pin and bearing pin is fixed by the axis plate.
This axis plate passes through bolt.
Concrete, the bearing location and installation is in corresponding mechanism, connecting bearing uses the bolt location and installation on bearing, the switching guide is hinged on first bearing pin by oscillating bearing, the first bearing pin location and installation is connecting on the bearing, balance arm is hinged with switching guide lower end by second bearing pin again, the balance arm both sides are hinged by lineoutofservice signal pull measurement bearing pin and cable wire enclosed socket, one end of wire rope just is fixedly mounted on the cable wire enclosed socket, the end of all bearing pins all uses the axis integrated circuit board to live in the wire rope balancer of the present invention, in case bearing pin skids off.
Owing to adopted such scheme, the present invention has following characteristics: be a kind of comprehensive wire rope balancer, supporting capacity is big, simple in structure, cost is low, need not power supply, and it is reliable to only depend on mechanical system to connect, use lever principle and regulate voluntarily, make wire rope on three directions, can both realize stress equalization by both sides pull of steel wire difference.
Description of drawings

Fig. 2 is that schematic diagram is looked on the left side of the embodiment of the invention.
Number in the figure: (1) bearing; (2) axis plate; (3) balance arm; (4) second bearing pins; (6) switching guide; (8) first bearing pins; (9) connect bearing; (10) axle sleeve; (13) circlip for hole; (14) oscillating bearing; (15) cable wire enclosed socket; (16) lineoutofservice signal pull is measured pin; (17) bolt; (18) spring washer; (24) straight forced filling oil cup.
The specific embodiment
The present invention is further illustrated below in conjunction with the accompanying drawing illustrated embodiment.
As Fig. 2-shown in Figure 3, the installation direction of bearing 1 should be consistent with the direction of pull of haulage cable.With Bolt Connection the bearing 9 of connection is arranged on the bearing 1, connect on the bearing 9 and have pin-and-hole, first bearing pin, 8 two ends are connecting on the bearing 9 with axis plate 2 location and installation, switching has two mutual vertical but disjoint pin shaft holes on the guide 6, to accept first bearing pin 8 and second bearing pin 4, balance arm can be rotated around this two vertical axis, realize the wire rope stress equalization on this two direction.Switching guide 6 connects by oscillating bearing 14 with first bearing pin 8, and oscillating bearing 14 can rotate switching guide 6 around all directions.Inject lubrication oil by oilhole on first bearing pin 8 and straight forced filling oil cup 24 and realize the lubricated of oscillating bearing 14, also can adopt other lubricating system.
Balance arm 3 is hinged with switching guide 6 by second bearing pin 4, and second bearing pin, 4 two ends are fixed on the balance arm 3 with axis plate 2.Balance arm 3 both sides symmetries are equipped with two cable wire enclosed sockets 15 that are connected with wire rope, cable wire enclosed socket 15 connects with balance arm 3 usefulness bearing pins, this bearing pin can be that common bearing pin also can be that lineoutofservice signal pull is measured pin 16, in this example, be common bearing pin on one side, Yi Bian be that lineoutofservice signal pull is measured pin.
As shown in Figure 2, when left side lineoutofservice signal pull was bigger than the right lineoutofservice signal pull, balance arm 3 rotated counterclockwise around second bearing pin 4, loosen so left side wire rope has slightly, left side lineoutofservice signal pull reduces, and the right wire rope is tightened up, pulling force increases, and balance arm 3 rotates up to the both sides lineoutofservice signal pull and equates.
According to lever principle, when two wire rope were equal to second bearing pin, 4 distances, two wire rope are stressed to be equated.Suitably design two wire rope can make two lineoutofservice signal pulls proportional, to be suitable for the needs of different occasions to the distance of second bearing pin 4.Equal the twice of the right arm of force such as the left side arm of force, then the right lineoutofservice signal pull just can remain the twice of left side lineoutofservice signal pull.
When the stressed slip chart paper plane of wire rope, balance arm 3 and wire rope can rotate around first bearing pin 8.In addition, oscillating bearing 14 can be realized the omnibearing rotation of steel rope system, guarantees can both keep the both sides tension equalizer when wire rope is on all directions.
The present invention only relies on mechanical system, utilizes the balanced both sides of lever principle lineoutofservice signal pull, need not realize comprehensive equilibrium automatically by power supply, thereby the dependability height.This balance arm system bearing ability is big, not only is used for steel rope system, also can be used for the occasion that other needs symmetrical load.
The above-mentioned description to embodiment is can understand and apply the invention for ease of those skilled in the art.The person skilled in the art obviously can easily make various modifications to these embodiment, and needn't pass through performing creative labour being applied in the General Principle of this explanation among other embodiment.Therefore, the invention is not restricted to the embodiment here, those skilled in the art should be within protection scope of the present invention for improvement and modification that the present invention makes according to announcement of the present invention.
