Description
Technical field
The utility model relates to the safeguard protection facility, specifically a kind of catching device simple in structure, easy to operate, safe in utilization.
Background technology
As everyone knows, along with rapid development of social economy, the propelling day by day of process is built in urbanization, and building industry obtains development at full speed, and derrick crane is used more and more general, and the general tower crane of selecting is as main vertical transport instrument in skyscraper.But tower crane personnel falling accident often takes place during practice is produced, according to incompletely statistics data show etesian tower crane accident have over one hundred more than.Wherein owing to the staff does not have the fall event that the safeguard protection facility takes place to occupy considerable ratio when tower crane is with maintenance up and down.
Summary of the invention
The purpose of the utility model is the deficiency that overcomes above-mentioned prior art, provide a kind of easy to operate, safe in utilization, solve the tower crane staff up and down during tower crane, the catching device of accidental falling or landing appears.
The utility model can reach through following measure:
A kind of catching device comprises mounting bracket, cylinder, motor, is wound with steel wire rope on the cylinder; An end that it is characterized in that cylinder is provided with power transmission shaft, and power transmission shaft is connected with motor, and the other end of cylinder is provided with braked wheel; Braked wheel is provided with cam, ratchet and brake axle, and power transmission shaft and brake axle are rack-mount through bearing respectively, and arc pendulum rod is hinged through bearing pin and support; Arc pendulum rod one end is provided with roller; The other end is provided with ratchet, and roller links to each other through the spring adjustment screw that governor spring and support are provided with, and roller contacts with cam under the effect of governor spring.
The described steel wire rope of the utility model end is provided with safety belt, to improve security performance.
The described support of the utility model is provided with baffle plate, to reach the purpose of the anti-foreign matter of rain-proof dust-proof.
The described cylinder of the utility model both sides are provided with baffle ring, to realize steel wire rope conductor rope, the effect of retaining rope, are to be unlikely to the snarling rope when making progress for personnel during stall electric motor recovery steel wire rope, and ward off rope device forbids that steel wire rope jumps out cylinder.
When the utility model uses it is installed on the tower crane frame through support, motor is charged always or switch control is arranged when tower crane is started working, and is upper and lower or when going out the maintenance tower crane as the staff; Be with safety belt,, accelerated with the braked wheel overhead cam rotational frequency that cylinder is fixed together when personnel slip or other reasons when causing drum rotation speed to overflow; The roller whipping amplitude that drives arc pendulum rod one end strengthens, and the ratchet of the arc pendulum rod other end gets in the ratchet on the braked wheel, stops braked wheel to rotate; And then prevent cylinder to rotate, after the PERSONNEL RECOVERY is normal, and to the segment distance of walking in the other direction that falls; The roller of arc pendulum rod one end moves along the cam extrados; Under the governor spring effect, ratchet breaks away from the ratchet on the braked wheel, recovers normal.Spring adjustment screw and governor spring can cylinder rotary speed, the speed of just regulating personnel descending, personnel's torque motor rollback steel wire rope and evenly be entangled in steel wire rope on the cylinder upwards or when returning through guide rope device.When personnel arrive the tower crane bottom down, can be entangled in safety belt on the fixture or breakaway torque motor power supply, prevent to reclaim rope.This device is applicable to that any vertical operation needs the place of anti-falling protection.
Description of drawings
Fig. 1 is a kind of structural representation of the present invention.
Fig. 2 is that the A of Fig. 1 is to zoomed-in view.
The specific embodiment
Below in conjunction with accompanying drawing the present invention is further described.
As shown in the figure, a kind of catching device comprises mounting bracket 1, cylinder 2, motor 3; Be wound with steel wire rope 4 on the cylinder 2, an end of cylinder 2 is provided with power transmission shaft 5, and power transmission shaft 5 is connected with motor 3; Motor 3 adopts torque motor and is connected with support 1 through pole 6, and the other end of cylinder 2 is provided with braked wheel 7, and braked wheel 7 is provided with cam 8, ratchet 9 and brake axle 10; Power transmission shaft 5 is installed on the support 1 through bearing respectively with brake axle 10, and the structure of above-mentioned each part and the interconnected relationship between them are identical with prior art, and this does not give unnecessary details; Arc pendulum rod 11 is hinged through bearing pin and support 1, and arc pendulum rod 11 1 ends are provided with roller 12, and the other end is provided with ratchet 13; Roller 12 links to each other through the spring adjustment screw 15 that governor spring 14 and support 1 are provided with, and roller 12 contacts with cam 8 under the effect of governor spring 14, and the described steel wire rope of the utility model end is provided with safety belt 17; To improve security performance, described support 1 is provided with baffle plate, to reach the purpose of the anti-foreign matter of rain-proof dust-proof; In addition, the described cylinder of the utility model 2 both sides are provided with baffle ring 16, to realize steel wire rope conductor rope, the effect of retaining rope; Be to be unlikely to the snarling rope when making progress for personnel during stall electric motor recovery steel wire rope, ward off rope device forbids that steel wire rope jumps out cylinder.
