Description
Technical field
The utility model relates to electric block, particularly relates to a kind of brake equipment of electric block driving system.
Background technology
In order to prevent that electric block was when lifting heavy articles, uncontrollable lifted weight thing quickens tenesmus, therefore designed the safety device of electric block, it is the driving system brake equipment of electric block, as China Patent No. CN200920091992.8, patent name is " a kind of electric block sure brake ", this scheme is by sensor installation in gear case, and sensor obtains signal by detecting the gear ring number of teeth, passes to drawing magnetism, drawing magnetism upwards spurs steel rope, the afterbody of steel rope direct pull ratchet, ratchet head into ratchet and block ratchet, and ratchet stops operating, ratchet inner ring brake hoop and reel produce friction, impose restrictions on reel and be rotated further, thereby reach the purpose of safety arrestment, the shortcoming of its technical scheme is: one, adopt the sensor signal, complex structure, the productive costs height, two, adopt magnet pulling steel rope, intermediary agency is many, action stability is poor, and three, make, trouble is installed.
Summary of the invention
The purpose of this utility model is in order to overcome the shortcoming of prior art, to provide a kind of ratchet to contact all the time with ratchet, do not need intermediate drive spare, braking the reliability height, and is simple in structure, the electric block driving system brake equipment that productive costs is low.
The technical scheme of the utility model electric block driving system brake equipment is: comprise chain-wheel box, one end mounting teeth roller box of chain-wheel box, sprocket spindle is installed in the chain-wheel box, the gear main shaft is installed in the gear case, one of sprocket spindle links to each other with motor shaft, on the other end of sprocket spindle big gear wheel is installed, big gear wheel is meshed with gear main shaft in the gear case, it is characterized in that being equipped with on the described gear main shaft the dull and stereotyped and brake transmission gear of brake, the brake transmission gear contacts with sprocket spindle, dull and stereotyped and the installation brake ratchet between the transmission gear that brakes in brake, described brake ratchet comprises the gear teeth, forms teeth groove between each gear teeth, in gear case, be equipped with set pin, the brake ratchet is installed on the set pin, is equipped with torsion spring under the brake ratchet, the brake ratchet contacts with the gear teeth of brake ratchet.
Electric block driving system brake equipment of the present utility model, dull and stereotyped and the brake transmission gear of brake is installed on the gear main shaft, be equipped with the brake ratchet between brake flat board and the brake transmission gear, in gear case, install and fix pin, the brake ratchet is installed on the set pin, during normal operation, the brake ratchet contacts with the gear teeth cw of brake ratchet, the ratchet that promptly brakes slides along the inclined-plane of the brake ratchet gear teeth, the brake ratchet remains circumscribed with the outer ring of brake ratchet, but when hanging object overweight uncontrollable and when tenesmus, the driving system reversing, driving the brake ratchet rotates counterclockwise, the ratchet that brakes this moment contacts with facing directly of the brake ratchet gear teeth, snap in the teeth groove of respectively taking turns between cog, brake ratchet chucking is stopped operating, the dull and stereotyped upwards jack-up of brake simultaneously, brake ratchet and brake flat board and brake transmission gear are tightened mutually, the brake ratchet drives the brake flat board and the brake transmission gear stops operating, the brake transmission gear drives sprocket spindle and stops operating, make the lifting chain stop tenesmus, thereby avoided contingencies such as the personal injury that may cause and article breaking-up.This programme ratchet and ratchet be direct contact all the time, need not centre part, and the reliable in action height has improved the safety in utilization of electric block, and is simultaneously simple in structure, installs very conveniently, and productive costs is low.
Electric block driving system brake equipment of the present utility model is installed friction lining between described brake ratchet and the brake flat board, and friction lining has been arranged, and chucking is more firm between brake ratchet and the brake flat board.Between described brake ratchet and the brake transmission gear wear plate is installed, wear plate has been arranged, the brake ratchet is more reliable with brake transmission gear chucking.
