Abstract
The utility model relates to an electric block with a limit protective device. The electric block with the limit protective device comprises a motor, a transmission mechanism, a roll, a steel wire rope and a hanging hook, the transmission mechanism is connected with the motor, the roll is connected with the transmission mechanism, the steel wire rope is arranged below the roll, the hanging hook is connected with the steel wire rope, a limit switch is arranged below the roll, the limit switch is connected with the transmission mechanism through a wire lead, and a hanging ring is arranged on the steel wire rope below the limit switch. When in use, the limit protective device is started and the hanging hook lifts, if the hanging hook is contacted with the hang ring, the limit switch controls the transmission mechanism to stop motion, so that the roll is effectively protected and not damaged easily. Secondly, a limit switch device is arranged on the position of 200 millimeters below the roll, so that sufficient hanging space can be provided, and at the same time the roll can be effectively protected from being damage of the hanging hook.
Description
Technical field
The utility model relates to mechanical field, is specifically related to a kind of fender guard that uses at electric block, particularly a kind of electric block with limiting and protecting device.
Background technology
Electric block is called for short hoist ceiling crane, is a kind of small-sized weight-lifting equipment.Most electric blocks use button to follow manipulation on ground by the people, or also can handle or adopt wired distance control in driver's cab.Electric block generally is installed in single-beam crane, crane in bridge type, and transfer crane is on the overhang crane.Transform a little, can also be used as winch.Therefore, it is to raise labour efficiency, the indispensable machinery of improving working conditions.The component part of electric block has: motor, transmission device, reel and sprocket wheel.Application: promote, pull, load and unload weight, the oil tank face-down bonding, such as installation and the movement of various big-and-middle-sized concretes, steel structure and mechanical equipment, be applicable to the mechanical equipment that the civil construction project of building and installation company, factories and miness and bridge construction, electric power, boats and ships, Automobile manufacturing, building, highway, bridge, metallurgy, mine, side slope tunnel, hoistway are administered the infrastructural projects such as protection.
Electric block is when hoisting heavy, owing to being subject to the impact of the factors such as distance and sight line, in the process of lifting heavy, suspension hook is too top, easily squeezes bad reel, causes equipment not move.
Therefore, produce a kind of simple in structure, easy to operate, high efficiency, long service life has the electric block with limiting and protecting device of certain protective role to steel rope, have wide market outlook.
Summary of the invention
For the deficiencies in the prior art, the utility model provides a kind of simple in structure, easy to operate, high efficiency, long service life, steel rope is had the electric block with limiting and protecting device of certain protective role.
The technical solution of the utility model is such realization: a kind of electric block with limiting and protecting device; comprise motor, with the interconnective transmission device of motor, the reel that is connected with transmission device, the steel rope that is arranged on reel below, the suspension hook that is connected with steel rope; described reel below is provided with limit switch; limit switch is connected with transmission device by wire, and the steel rope below limit switch is provided with hoisting ring.
Described limit switch is arranged on 200 millimeters places, reel below.
The utlity model has following good effect: at first this product structure is simple, comprise motor, with the interconnective transmission device of motor, the reel that is connected with transmission device, be arranged on the steel rope of reel below, the suspension hook that is connected with steel rope, described reel below is provided with limit switch, limit switch is connected with transmission device by wire, steel rope below limit switch is provided with hoisting ring, in use, open this device, suspension hook is in the process that rises, in case run into hoisting ring, limit switch will be controlled the transmission device stop motion, and actv. has been protected reel, is not easy to make reel to receive destruction; Secondly, this product limit switch is arranged on 200 millimeters places, reel below, and sufficient lifting space can be provided, and can protect reel to avoid the destruction of suspension hook by actv. again.
Description of drawings
Fig. 1 is structural representation of the present utility model.
The specific embodiment
As shown in Figure 1; a kind of electric block with limiting and protecting device; comprise motor 1, with motor 1 interconnective transmission device 2, the reel 3 that is connected with transmission device 2, be arranged on the steel rope 7 of reel 3 belows, the suspension hook 8 that is connected with steel rope 7; described reel 3 belows are provided with limit switch 5; limit switch 5 is connected with transmission device 2 by wire, and the steel rope 7 below limit switch 5 is provided with hoisting ring 6.
Described limit switch 5 is arranged on 200 millimeters places, reel 3 belows.
This product in use; below distance reel 3, locate to fixedly mount a limit switch 5 for 200 millimeters; the power lead of the contactless switch on the bont was connected on the normal battle of limit switch 5, and the other end of limit switch is mixed hoisting ring 6, and this hoisting ring 6 is fixed on the steel rope 7 of limit switch below; in the process that after suspension hook 8 is opened, rises; run into hoisting ring 6, limit switch 5 actions pass to the contactless switch that control is risen with signal; thereby the effect of protection reel 3 is played in outage.
Claims (2)
1. electric block with limiting and protecting device; comprise motor (1), with the interconnective transmission device of motor (1) (2), the reel (3) that is connected with transmission device (2), the steel rope (7) that is arranged on reel (3) below, the suspension hook (8) that is connected with steel rope (7); it is characterized in that: described reel (3) below is provided with limit switch (5); limit switch (5) is connected with transmission device (2) by wire, and the steel rope (7) in limit switch (5) below is provided with hoisting ring (6).
