The transmission of many suspension centre two dimensions is from row's rope combined type loop wheel machine
Technical field
The utility model belongs to the stage machinery field, and the transmission of especially a kind of many suspension centre two dimensions is from row's rope combined type loop wheel machine.
Background technology
The flybar machine is arenas, conference centre, performs in a radio or TV programme the essential equipment in performance places such as the Room, music hall, is the carrier of light of stage, setting stage property, stage curtain.Existing topping winch mainly is made up of brake snub motor and cylinder, on cylinder, is wound with many suspension centres steel rope, and this many suspension centres steel rope connects suspension rod or other elevator stage equipment of stage curtain through the deflection sheave of loop wheel machine top.At present, the cylinder of topping winch only is rotated action, and does not carry out horizontal displacement in operational process, is easy to generate the steel rope superposition phenomenon thus, influences steel rope row rope on the cylinder.The reel of existing loop wheel machine is to lean on the deflection sheave group of machine top to arrange rope, need the deflection sheave group be installed at (about 3 meters) on the certain altitude, and the cornerite of pulley and steel rope is reasonable in the time of just can remaining on the cylinder rotation.It is thus clear that existing flybar machine not only needs bigger installing space, but also girder steel and the building girder that need set up deflection sheave have increased the weight of stage steel structure, thereby have increased the building structure cost.In fact, existing many arenas all can not satisfy the requirement of setting height(from bottom), and flybar can't be installed, and therefore the urgent need development is a kind of can be under the condition of insufficient space, and row's rope is realized the equipment of flybar function voluntarily.

The specific embodiment
Through specific embodiment the utility model is done further to detail below, following examples are descriptive, are not determinate, can not limit the protection domain of the utility model with this.
A kind of many suspension centre two dimension transmission rope arranging automatically combined type loop wheel machines comprise bearing 11, frame 15, brake snub motor 1, row's rope drum 3, and the bearing symmetry is packed in the bottom of frame, and the brake snub motor output shaft drives the rotation of row's rope drum.
The innovation part of the utility model is: the two ends of arranging rope drum are rotatably installed in left support wallboard 2 and right the support between the wallboard 8, and it is fixing to be positioned at the pull bar 7 of arranging the rope drum outside through symmetry between the two support wallboards.On pull bar, arrange to be equipped with and press rope clip 6.Reductor braking motor supports the wallboard fixed installation with a left side.Row's rope drum two ends are installed in through bearing 20 and support on the wallboard, between bearing and the support wallboard bearing gland 19 are installed and carry out axial location.Support on the sliding thick stick 10 that the wallboard bottom is slidingly mounted on the symmetry installation of upper rack two ends institute.Vertically install a moving substrate 9 in frame with respect to the other end of brake snub motor; Level installs the horizontal screw bolt 17 that installs into drum on this moving substrate; This screw rod matches with the nut 21 that install in the place, cylinder side plate 18 axle center of row's rope drum end, and screw rod is identical with row's rope drum pitch.On row's rope drum lower framework, deflection sheave group 13 is installed.Row's rope drum is the 4-7 suspension centre, and said deflection sheave group comprises a corresponding 4-7 deflection sheave.Row's rope drum is 5 suspension centres in the present embodiment, and the deflection sheave group comprises corresponding 5 deflection sheavies that are provided with.
Outside face at row's rope drum is equipped with the rope creep protection device; This rope creep protection device is made up of the rope creep protection pinch roller 4 of corresponding each suspension centre of a row and the electrode 5 of corresponding each rope creep protection pinch roller bottom, and row's rope creep protection pinch roller and electrode are installed between the two support wallboards through installation shaft separately is transversely arranged respectively.
In deflection sheave group bottom broken rope protector is installed all, this broken rope protector is made up of one group of electrode 14 of corresponding each deflection sheave group, and this group of electrode is packed on the frame.
Bearing is provided with insulation sleeve, and concrete structure is: each bearing of frame bottom constitutes by upper pedestal 22 and symmetrical lower base 24, and upper pedestal is installed between the symmetrical lower base through bearing pin, is set with insulation sleeve 23 between upper pedestal and symmetrical lower base and the bearing pin.Bearing can directly be stuck on I-beam section 12 guide rails, and is easy to connect.Play vibrations insulation and electric insulating between machine and the stage grid top steel structure simultaneously.
On the output shaft of brake snub motor, install and be furnished with encoder interfaces and can realize computer controlled.Counting machine 16 is installed on the deceleration output shaft of brake snub motor, and this counting machine is a mechanical counter, and this counting machine can be realized Stroke Control.
The principle of work of the utility model is:
The rotation of brake snub motor-driven row rope drum because the nut of row's rope drum one end matches with standing screw, is supported wallboard parallel motion on the sliding thick stick of upper rack thereby order about two.Because screw rod is identical with row's rope drum pitch, can realize that steel rope is positioned at and be equal to the horizontal displacement of arrange rope drum on row's rope drum, thereby the row certainly of realization loop wheel machine restricts.Because screw rod is arranged at the inside of row's rope drum, effectively reduced the whole shared installing space of loop wheel machine, structure is more compact.
The principle of work of rope creep protection device is: when steel rope gets loose; Its with relative position on the slack rope pinch roller installed contact; The original electric insulating state of slack rope pinch roller is broken; The electrode of slack rope pinch roller bottom is connected, thereby shuts down and report to the police through controller, and prompting stops equipment and overhauls.
The principle of work of broken rope protector is same as the rope creep protection device, and steel rope breaks off the back and contact with the electrode of deflection sheave group bottom, breaks original electric insulating state, thereby through the controller shutdown and report to the police, points out equipment is stopped and overhauling.
