Abstract
The utility model discloses an auxiliary brake apparatus for a span winch rotary mechanism, including an annular connecting steel plate, an auxiliary brake disc, a safety brake and a pumping station; the annular connecting steel plate is fixed on a tower pole under a winch platform by means of a countersink screw; the auxiliary brake disc is a circular ring structure which is assembled by a plurality of sections of steel plates; the auxiliary brake disc and the annular connecting steel plate are fixed to form an annular convexity through welding; the pumping station is arranged on top of the winch platform and the safety brake is fixedly arranged under the winch platform, thereby a brake clamp of the safety brake is corresponding to the annular convexity formed by the auxiliary brake disc. The utility model can effectively improve the brake performance of the span winch rotary mechanism on the basis of the prior art.
Description
Technical field
The utility model relates to the brake system in the hoisting crane, particularly a kind of complemental brake system of drum type brake span winch swing type mechanism.
Background technology
High pedestal jib crane is used in harbour, the water power building ground widely, hoisting crane utilization grab bucket, suspension hook, container spreader load and unload various goods, in traditional high pedestal jib crane, the swing type mechanism brake system is generally the fluid pressure type brake system or is the pneumatic brake system.The fluid pressure type brake system is carried out braking maneuver entirely by driver's stretcher acting by hydraulic ram, and the application force of brake pedal is quite big to driver's effect, and driver's of long duration labour intensity is just too big.Also having a kind of in addition is the pneumatic brake system, utilizes the work of compressed air-driven drg, and this brake system has stationarity poor, the characteristics that impulsive force is big.Meanwhile, traditional round cartridge type span winch tends to occur the ineffective situation of rotary braking.
The utility model content
The utility model provides a kind of complemental brake system of drum type brake span winch swing type mechanism, sets up the rotary braking performance that this device can effectively improve existing drum type brake span winch on the basis of original brake equipment.
The technical solution adopted in the utility model is: a kind of complemental brake system of drum type brake span winch swing type mechanism, this complemental brake system connects steel plate, auxiliary braking dish, sure brake, pumping plant by ring-type and forms, ring-type connects steel plate and is fixed on the king-post of board below with flathead screw, the auxiliary braking dish is the ring assembling structure that steel is made, and the ring-type that is welded in segmentation connects on the steel plate and forms annular projection, pumping plant and sure brake are divided into the board upper and lower, make the brake clip of sure brake can be corresponding with the annular projection that the auxiliary braking dish forms.
Wherein, described sure brake model is SH15-3, and the pumping plant that drives sure brake is CE8L-20; The high 200mm of described auxiliary braking dish, thickness is 30mm.
Described ring-type connects the cyclic structure of steel plate for being spliced into by the several piece steel plate, and its thickness is 10～12mm.
The beneficial effects of the utility model are: the deceleration and stopping performance that can effectively improve drum type brake span winch swing type mechanism on prior art.
Description of drawings
Fig. 1 is the utility model embodiment scheme drawing;
Fig. 2 is the A-A view of Fig. 1.
The specific embodiment
For the easier quilt of the utility model is understood, the utility model is done being described in more detail below in conjunction with the specific embodiment.
Consult Fig. 1, Fig. 2, a kind of complemental brake system of span winch swing type mechanism, this complemental brake system is made up of ring-type connection steel plate 3, auxiliary braking dish 2, sure brake 5, pumping plant 6, steel plate 3 usefulness flathead screws are fixed on the board 1 below king-post 4, the ring assembling structure that auxiliary braking dish 2 is made for steel, and be welded in ring-type and connect on the steel plate 3 and form annular projection, pumping plant 6 and sure brake 5 are divided into board 1 upper and lower, make the brake clip of sure brake 5 can be corresponding with the annular projection that auxiliary braking dish 2 forms.
Wherein, described auxiliary braking dish 2 is connected all circular ring structures for being spliced into by the several piece steel plate of steel plate 3 with ring-type.
Described span winch is MQ600B, and sure brake 5 models are SH15-3, and the pumping plant 6 that drives sure brake 5 is CE8L-20; The high 200mm of described auxiliary braking dish, thickness is 30mm; It is 10～12mm that ring-type connects steel plate 3 thickness.
The master cock of sure brake 5 is arranged in the driver's cab on the board 1, and the driver can operate complemental brake system as required, to reach the purpose of turning round brake in time, effectively.
