Abstract
The invention discloses a self-balancing hanger. The self-balancing hanger comprises a hanger body, four supporting feet, four lifting lugs, balance sensors, two motors, two gear boxes, a bracket, two screw rods and two nuts, wherein the four supporting feet are fixed on the periphery of the lower side of the hanger body; the four lifting lugs are uniformly distributed on the upper side of the hanger body; the balance sensors are arranged at the two ends of the bracket; the two screw rods are horizontally arranged on the bracket and are driven through the gear boxes; the gear boxes are driven through the motors; the nuts are arranged on the screw rods and are connected with the screw rods through threads. By adopting the structure, the self-balancing hanger has a simple structure, is low in cost, and can automatically control the center of gravity, so as to improve the safety of the hanger.
Description
Technical field
The present invention relates to a kind of suspender, particularly a kind of self-balance sling.
Background technology
Suspender is the device of suspender weight in elevator machinery, and hanging and getting the most frequently used suspender of work piece is suspension hook, and other also have suspension ring, hoisting suction cup, clamp and pallet fork etc., are widely used in hoisting and hanging industry.But suspender gets some longer weights such as section bar series products hanging, this kind of product length is longer, easily occur to break away and tilt in the process of lifting, thus change center-of-gravity position, suspender is made and then to tilt finally easily to cause weight landing to cause contingency, potential safety hazard is very large, therefore need a kind of can for this type of weight adjust that suspender center-of-gravity position avoids weight to break away at any time can the suspender of self-equalizing center of gravity.
The open book notification number 103754750A of Chinese patent, publication date 2014-04-30 discloses a kind of suspender, comprise lattice suspension bracket, described lattice suspension bracket comprises two parallel relative crossbeams and at least two vertical racks and is located at support beam on crossbeam, described crossbeam is provided with at least two chain slings, and described support beam is provided with at least one pair of hook.The suspender of this suspender can the multiple crystallizer of handling or dummy bar head simultaneously, adopts suspender of the present invention to reduce labor strength, simplifies more changing jobs of crystallizer and dummy bar head, shortens online replacing construction, enhance productivity.But this suspender cannot regulate center of gravity, thus can not ensure the centre of gravity adjustment of lifting, easy run-off the straight and landing, safety is not high.
Summary of the invention
Technical matters to be solved by this invention is to provide a kind of self-balance sling that automatically can adjust center-of-gravity position.
For solving the problems of the technologies described above, the technical solution adopted in the present invention is:
A kind of self-balance sling, comprise suspender main body, it is characterized in that: it also comprises four legs, four hangers, balance sensor, two motors, two gears case, support, two screw rods and two nuts, described leg is vertically arranged and upper end is fixed on the downside of suspender main body, four legs are evenly distributed on surrounding on the downside of suspender main body, support is fixed in the middle of on the downside of suspender main body, described two balance sensors are symmetricly set on support two ends, described two screw rods to be horizontally set on inside support and to be parallel to each other, screw rod two ends are rotated and to be arranged in support on the sidewall of two ends, a screw rod one end is connected with a gear case and is driven by gear case, another root screw rod one end is connected with another gear case and is driven by gear case, described two gears case are driven by the motor of correspondence respectively, described two nuts are separately positioned on a screw rod in two screw rods and nut is connected with screw flight, described two nut horizontal directions are symmetricly set on both sides in support.
Further, described four hangers to be fixed on suspender main body upper side and four rectangular distributions of hanger, and described four hangers all arrange along rectangle diagonal line and arrange with rectangular centre point symmetry.
Further, described motor is stepping motor.
Further, the suspension hook support for connecting shackle is evenly distributed with on the downside of described suspender main body.
The present invention compared with prior art, have the following advantages and effect: self-balance sling structure is simple, with low cost, the degree of balance of suspender in hoisting process is detected by balance sensor, when the center of gravity generation deflection of suspender time, control motor-driven gear case thus control nut to slide thus the center of gravity again controlling suspender, make it balance, achieve self-equalizing like this, improve the safety of suspender.
Accompanying drawing explanation
Fig. 1 is the schematic diagram of self-balance sling of the present invention.
Fig. 2 is the upward view of self-balance sling of the present invention.
Detailed description of the invention
Below in conjunction with accompanying drawing, also by embodiment, the present invention is described in further detail, and following examples are explanation of the invention and the present invention is not limited to following examples.
As shown in the figure, self-balance sling of the present invention comprises suspender main body 1, it also comprises four legs 2, four hangers 3, balance sensor 4, two motors 5, two gears case 6, support 7, two screw rods 8 and two nuts 9, leg 2 vertically arranges and upper end is fixed on the downside of suspender main body 1, four legs 2 are evenly distributed on surrounding on the downside of suspender main body 1, support 7 is fixed in the middle of on the downside of suspender main body 1, two balance sensors 4 are symmetricly set on support 7 two ends, two screw rods 8 to be horizontally set on inside support 7 and to be parallel to each other, screw rod 8 two ends are rotated and to be arranged in support 7 on the sidewall of two ends, screw rod 8 one end is connected with a gear case 6 and is driven by gear case 6, another root screw rod 8 one end is connected with another gear case 6 and is driven by gear case 6, two gears case 6 are driven by the motor 5 of correspondence respectively, two nuts 9 are separately positioned on a screw rod 8 in two screw rods 8 and nut 9 is threaded with screw rod 8, two nut 9 horizontal directions are symmetricly set on both sides in support 7.By such structure, self-balance sling of the present invention carries out Real-Time Monitoring by the degree of balance of balance sensor 4 pairs of suspenders, when suspender is in hoisting process when run-off the straight, balance sensor 4 monitor tilt signals and feed back to motor 5 by motor 5 pinion case 6 thus control nut 9 slide along screw rod 8, thus by the weight compensating of nut 8, the centre of gravity adjustment of suspender is gone back, ensure the balance of whole suspender.
Four hangers 3 to be fixed on suspender main body 1 upper side and four rectangular distributions of hanger 3, four hangers 3 all arrange along rectangle diagonal line and arrange with rectangular centre point symmetry, by such setting, ensure that 4 hangers are when lifting, the final Impact direction of messenger wire can be pooled to suspender point midway, thus ensure that center of gravity is in suspender central authorities, with easily controlling.Motor 5 is stepping motor, adopt stepping motor can convenient and accurately to nut 9 slip position and distance control.Be evenly distributed with the suspension hook support 10 for connecting shackle on the downside of suspender main body 1, can be lifted needs hanging belt weight by suspension hook support 10.
Above content described in this specification sheets is only casehistory made for the present invention.Those skilled in the art can make various amendment or supplement or adopt similar mode to substitute to described specific embodiment; only otherwise depart from the content of specification sheets of the present invention or surmount this scope as defined in the claims, protection scope of the present invention all should be belonged to.
