Abstract
The invention relates to a crane for lifting lamps or a setting device of a studio and a stage. The crane comprises a gear motor and a steel wire rope coiling block which are mounted on a rack; the output end of the gear motor is connected to a main shaft of the steel wire rope coiling block. The crane further comprises a cable reel, a first transmission wheel, a second transmission wheel and a transmission belt; a centre shaft of the cable coiling block is fixedly connected to the rack; the first transmission shaft is mounted on a shaft of the steel wire rope coiling block; the second transmission wheel is mounted on the center shaft of the cable reel; the first transmission wheel and the second transmission wheel are connected through the transmission belt. With the adoption of the crane, the lifting and synchronous extending and contracting cables of the lamps or the setting device are integrally combined, thus the space for devices is reduced, and the mounting cost and difficulty in construction and device debugging are decreased; simultaneously, the surplus power of the gear motor is fully utilized, and as a result, the device manufacture cost and operation cost are saved.
Description
Technical field
The present invention relates to a kind of loop wheel machine for lifting studio, stage lamp or scenery device.
Background technology
Along with the needs of studio, the development of stage program, studio, stage technique and equipment to be had higher requirement, the equipment that studio, stage need to be installed is more and more.For the lifting of studio, stage lamp or scenery device, need to configure the loop wheel machine of hoisting lamp or scenery device fixed mount, carry out lift adjustment and the layout of light fixture or scenery device.Also need to configure electric power and the signal cable undinding and rewinding drum of light fixture or scenery device, to realize respectively the twisted and released of the cable of light fixture on stage simultaneously.This scheme need to configure loop wheel machine and twisted and released of the cable reel simultaneously, and therefore equipment occupation space is large, and studio, stage erected cost are high, and construction is complicated, equipment debugging difficulty is large.In addition, for twisted and released of the cable can be synchronizeed with loop wheel machine lifting, twisted and released of the cable reel must be equipped with synchronising torque motor.The market price of general existing every torque motor is more than 4000 yuan, relatively costly, has increased equipment user's acquisition cost, and traction and the competitive power of product are affected.Therefore, need a kind of space, cost is low, debugging difficulty is little single-lift hoisting equipment saved of development badly.
Summary of the invention
The technical problem to be solved in the present invention is to provide a kind of loop wheel machine with cable winder for studio, stage, to overcome the defect that studio, stage lamp or scenery device expense are high, construction is complicated, equipment debugging difficulty is large.
For realizing above-mentioned technical matters, the invention provides a kind of loop wheel machine with cable winder for studio, stage, for the loop wheel machine of studio, stage lamp or scenery device, comprise rack-mounted reducing motor and cable drum, the mouth of described reducing motor connects described cable drum main shaft, also comprise cable reel, the first power wheel, the second power wheel and driving band, the center shaft of described cable reel is fixedly connected in described frame, and described the first power wheel is installed on the axle of described cable drum; Described the second power wheel is installed on the center shaft of described cable reel; Between described the first power wheel, the second power wheel, be connected by described driving band.
The diameter ratio of described the first power wheel, the second power wheel, equates with the diameter ratio of cable drum, cable reel.
Preferably, described the first power wheel, the second power wheel are respectively belt pulley, and described driving band is belt.
Preferably, described the first power wheel, the second power wheel are respectively sprocket wheel, and described driving band is chain.
Preferred, the steel rope quantity of drawing hanging article on described cable drum is single or many.
Compared with prior art, the beneficial effect that the present invention has is: the cable winder that organically blended on the basis of existing loop wheel machine, reduce taking up room of equipment, and reduce erected cost and construction, equipment debugging difficulty.Meanwhile, utilize same reducing motor to drive cable drum and cable reel, realize twisted and released of the cable and lamp stand lifting is synchronous, take full advantage of the power more than needed of reducing motor, saved device fabrication cost and operation cost.
Brief description of the drawings
Fig. 1 is the loop wheel machine structural representation that the present invention carries cable winder.
In Fig. 1, the 1st, reducing motor, the 2nd, cable drum, the 3rd, small belt pulley--the first power wheel, the 4th, belt, the 5th, big belt pulley--the second power wheel, the 6th, cable reel, the 7th, frame.
Detailed description of the invention
Below in conjunction with detailed description of the invention, technical scheme of the present invention is further described in detail.
As shown in Figure 1, reducing motor 1 and cable drum 2 are arranged in frame 7, mouth connecting steel wire ropes reel 2 main shafts of reducing motor 1, the center shaft of cable reel 6 is fixedly connected in frame 1, the first power wheel--small belt pulley 3 is installed on the axle of cable drum 2, the second power wheel--big belt pulley 5 is installed on the center shaft of cable reel 6; Between small belt pulley 3, big belt pulley 5, be connected by belt 4.
Certainly, it will be understood by those skilled in the art that the first power wheel, the second power wheel can be also gear, connect by chain between two gears.But, because belt-driving has the flexible characteristic that can skid, can overcome steel rope and cable speed slightly when difference cable be easily tightened up the defect being even pulled off.Therefore adopting belt connecting steel wire ropes reel 2 and cable reel 6 is most preferred schemes.
For realizing synchronizeing of lifting lamp or scenery device and folding and unfolding cable, the linear velocity of steel rope and cable must be basic identical.For this reason, the diameter ratio between small belt pulley 3, big belt pulley 5, and diameter ratio between cable drum 1, cable reel 6 equates.
When device operation, reducing motor 1 drives cable drum 2 to rotate.Utilize reducing motor 1 to there is power more than needed, drive cable reel 6 synchronously to rotate by small belt pulley 3, belt 4, big belt pulley 5 transmissions.Meanwhile, utilize belt Flexible Transmission to have the characteristic of skidding, the motion that better realizes steel rope on cable drum is synchronizeed with the twisted and released of the cable on cable reel.Thereby, realized the lifting of light fixture or scenery device and the integral fusion of synchronous folding and unfolding cable.This scheme cable winder that organically blended on the basis of existing loop wheel machine, has reduced taking up room of equipment, has reduced erected cost and construction, equipment debugging difficulty.Meanwhile, utilize same reducing motor to drive cable drum and cable reel, realize twisted and released of the cable and lamp stand lifting is synchronous, take full advantage of the power more than needed of reducing motor, saved device fabrication cost and operation cost.
When device operation, reducing motor 1 drives cable drum 2 to rotate.From cable drum 2, can draw single wire rope or many steel ropes, be used for hanging multiple different light fixtures or scenery device.Be that this device had both been applicable to single-lift hoisting equipment, be applicable to again multiple spot loop wheel machine.
It should be noted last that, above detailed description of the invention is only unrestricted in order to technical scheme of the present invention to be described, although the present invention is had been described in detail with reference to preferred embodiment, those of ordinary skill in the art is to be understood that, can modify or be equal to replacement technical scheme of the present invention, and not departing from the spirit and scope of technical solution of the present invention, it all should be encompassed in the middle of claim scope of the present invention.
