Abstract

A chain type steel wire rope type electric block comprises a motor, a brake, a speed reducer, a control part, a hanging mechanism, a limiting mechanism, a role wheel, a steel wire rope, a lifting hook assembly and a steel wire rope guiding mechanism, wherein the motor and the brake are designed integrally, and are fixedly connected with a right bracket in the hanging mechanism, the speed reducer is fixedly connected with a left bracket in the hanging mechanism, the rope wheel, the steel wire rope and the steel wire rope guiding mechanism are arranged between the left bracket and the right bracket in the hanging mechanism, the limiting mechanism is installed below the left bracket and the right bracket in the hanging mechanism, props against and is matched with the control part on the shell of the motor, the motor is controlled to rotate forwardly and backwardly, and the steel wire rope is forcibly arranged in the rope groove of the rope wheel by the steel wire rope guiding mechanism, is in friction matching with an inclined surface with the included angle alpha of two sides in the rope groove, and lifts an heavy object by depending on the friction force. The chain type steel wire rope type electric block has the following advantages: the length of the steel wire rope is not limited, and lifting hooks can be arranged at two ends of the steel wire rope simultaneously, thus realizing the lifting and descending of the heavy object synchronously.

Description

A kind of chain type steel-wire rope type electric block
Technical field
The utility model relates to the electric block in the lifting weight-lifting equipment, particularly a kind of chain type steel-wire rope type electric block.
Background technology
Steel-wire rope type electric block is a kind of general lifting weight-lifting equipment that uses, the steel-wire rope type electric block that occurs on market and the data mainly includes housing, be arranged on the reel of housing inboard, be wound in the steel rope on the reel, drive reel motor rotating retarder and upper limit device, what have also is provided with lower caging device, because it is fixing that steel rope is an end, when electric block promotes weight, constantly be wrapped in steel rope on the reel, restriction because of the reel structure size, length of steel wire rope also is restricted, the length of steel wire rope that wants to extend must strengthen reel structure or make the steel rope multiple wraps, the structure of steel-wire rope type electric block is strengthened, and manufacturing cost increases, and installs and uses also inconvenient.
Summary of the invention
The utility model has overcome the deficiency that prior art exists, and provides a kind of rope capacity unrestricted, compact conformation, low cost of manufacture, steel-wire rope type electric block easy to install.
For achieving the above object, the utility model adopts following technical scheme: a kind of chain type steel-wire rope type electric block, comprise motor, drg, retarder, function unit, hitch, stop gear, rope sheave, steel rope, hook assembly, the steel rope guiding mechanism, described motor and brake integrated design, and be fixedly connected with right support in the hitch, left socle in described retarder and the hitch is fixedly connected, described rope sheave, steel rope and steel rope guiding mechanism place between the left and right sides support of hitch, described stop gear is installed on the below of hitch, cooperate with the function unit conflict that is installed in motor housing, ending of control motor reversed, described steel rope is forced to place in the grooving of rope sheave by the steel rope guiding mechanism, and with grooving in the angle of both sides be that the bevel friction of α cooperates, rely on friction force to promote weight.
The beneficial effects of the utility model are, the utility model utilizes the bevel friction of both sides in the grooving of steel rope and rope sheave and the friction force that produces promotes weight, therefore length of steel wire rope is unrestricted, compact conformation, low cost of manufacture, easy to install, and can suspension hook be set simultaneously at the two ends of steel rope, realize the function of lifting synchronously and decline weight.
Below in conjunction with the drawings and specific embodiments the utility model is further described.
Description of drawings
Fig. 1 is the structural representation of the utility model specific embodiment;
Fig. 2 is the right elevation of the utility model specific embodiment;
Fig. 3 is the A-A cutaway view of the utility model specific embodiment;
Fig. 4 is the rope sheave structural representation of the utility model specific embodiment.
Among the figure 1, drg, 2, motor, 3, rope sheave, 4, hitch, 41, right support, 42, left socle, 5, steel rope guiding mechanism, 51, press rope wheel, 52, block, 53, track adjusting wheel, 54, fixed pulley, 6, retarder, 7, steel rope, 8, stop gear, 9, hook assembly, 10, function unit.
The specific embodiment
As shown in drawings, a kind of chain type steel-wire rope type electric block, comprise motor (2), drg (1), retarder (6), function unit (10), hitch (4), stop gear (8), rope sheave (3), steel rope (7), hook assembly (9), steel rope guiding mechanism (5), described motor (2) and drg (1) integrated design, and connect with fixed with right support (41) in the hitch (4), left socle (42) in described retarder (6) and the hitch (4) is fixedly connected, described rope sheave (3), steel rope (7) and steel rope guiding mechanism (5) place between the left socle (42) and right support (41) of hitch (4), described stop gear (8) is installed on the below of left socle (42) and right support (41) in the hitch (4), cooperate with function unit (10) conflict that is installed in motor (2) shell, the rotating of control motor (2), described steel rope (7) is by the press rope wheel (51) in the steel rope guiding mechanism (5), block (52), track adjusting wheel (53), fixed pulley (54) is forced to place in the grooving of rope sheave (3), and with grooving in the angle of both sides be that the bevel friction of α (10 °-20 ° for good) cooperates, rely on friction force to promote weight, its principle of work is: earlier the utility model is hung by hitch (4), and the hook assembly (9) and the weight that will promote coupled together, then handle function unit (10), lock torque is opened and lost to drg this moment (1), motor (2) high speed revolution, export by NGWN type epicyclic reduction gear (6) low speed, rope sheave (3) is slowly run, the angle that makes both sides in the grooving with rope sheave (3) is that the steel rope (7) that the bevel friction of α cooperates moves up and down, driving weight rises or descends, when weight rises or drops to limit, stop gear (8) work makes motor (2) drg (1) that stops the rotation and close produce lock torque and cause safety misadventure to prevent weight from gliding.Advantage of the present utility model is that the length of steel rope (7) is unrestricted, and hook assembly (9) can be set simultaneously at the two ends of steel rope (7), realizes the function of lifting synchronously and decline weight.
