Abstract
The utility model discloses an antislip hook of a crane. The antislip hook of the crane comprises a speed measuring device, a motor and a reduction box. The speed measuring device is disposed on a connecting shaft for the motor and the reduction box. An auxiliary brake device is disposed on a low-speed shaft of the reduction box and comprises an electromagnetic sucker and a brake disk. The reduction box is provided with a reel, an incremental rotary encoder is disposed on the reel, and a controller disposed at the tail of the motor is connected to the incremental rotary encoder. The speed measuring device is disposed on the connecting shaft for the motor and the reduction box and is the rotary encoder, and accordingly the accuracy in speed measurement is improved and data exchange with a CPU (central processing unit) is facilitated. Safety of the crane with the antislip hook is improved greatly, normal slipping and stalled slipping of a hook during starting can be distinguished correctly, the antislip hook is simple in structure and convenient to use, safe operation of the crane can be guaranteed, and production accident rate can be lowered.
Description
Technical field
The utility model relates to a kind of anti-slide hook device, specifically relates to a kind of anti-slide hook device that is used for hoisting crane, belongs to mechanical field.
Background technology
At present, hoisting crane opens when hanging or weight descends in hoisting process slide hook phenomenon because of staring torque occurs in because of electric or overweight reason diminishes in the course of the work sometimes.Can damage lifting thing and equipment, also personal injury accident may take place.The control part of a lot of these type of devices is fairly simple, and when being difficult to pick out hoisting crane suspention startup, normal again situation about rising was protected the trace downslide after the suspension hook trace glided as stall condition.Most of motors are when starting because all there is such phenomenon in the factor of staring torque, if at the appointed time with stroke in, suspension hook recovers to rise, this is a kind of normal condition fully.
The utility model content
Deficiency to the prior art existence; The utility model technical matters to be solved is; A kind of crane gliding-proof hook device is provided, can correctly distinguishes normal downslide of suspension hook and stalled glide when starting, simple in structure; Easy to use, can guarantee the hoisting crane safe in operation, reduce the industrial accident incidence.
For solving the problems of the technologies described above; The technical scheme that the utility model is taked is that a kind of crane gliding-proof hook device comprises velocity measuring device; It also comprises motor and drop-gear box; Velocity measuring device is arranged on the adapter shaft of motor and drop-gear box, and the slow-speed shaft of drop-gear box is provided with additional brake gear, and additional brake gear comprises a magnetic chuck and a brake disk; Said drop-gear box is connected with reel, and reel is provided with an incremental rotary encoder, and incremental rotary encoder is connected in the controller of motor afterbody; Said controller comprises a speed signal circuit board for receiving, and the speed signal circuit board for receiving connects the signaling conversion circuit plate, and the signaling conversion circuit plate connects control desk, and control desk connects motor and magnetic chuck.
Optimize, above-mentioned crane gliding-proof hook device, its velocity measuring device are absolute value formula rotary encoder, velocity measuring device connection speed signal receiving circuit plate.
The utility model is provided with velocity measuring device on the adapter shaft of motor and drop-gear box, velocity measuring device adopts rotary encoder, has improved the accuracy of tachometry, and has been convenient to carry out data exchange with CPU; Adopt the crane safety property of the utility model to improve greatly, can correctly distinguish normal downslide of suspension hook and stalled glide when starting, simple in structure, easy to use, can guarantee the hoisting crane safe in operation, reduce the industrial accident incidence.
