Background
The large-scale port crane comprises a shore container crane, a loading and unloading bridge, a portal crane and the like. These cranes typically have a high hoisting height, a large boom length, and a large operating class for frequent and rapid loading and unloading of cargo from large cargo vessels. In order to meet the requirements, the large-scale port crane is designed into special equipment with a complex structure, a large windward area and a high gravity center. Most of large ports and wharfs in China are distributed at seaside, and the southeast coast is an area where typhoons and strong gusts frequently occur, which brings serious potential safety hazards to the normal use of the equipment. In order to prevent the large-scale crane in the port from tipping over under typhoons and strong gusts, the national standard GB/T6067.1-2010 part 1 of the safety code of hoisting machinery: the general rules clearly require that the crane needs measures for preventing typhoon and gust.
The typhoon prevention device mainly comprises an iron shoe, an anchorage, a windproof guy cable, a windproof pull ring and the like, the measures belong to fixed facilities and are operated purely manually, the design meets the requirements, and the performance is not easy to change after the field installation and debugging of the equipment are finished. The gust prevention device mainly comprises an anti-climbing device, a rail clamping device, a rail jacking device, a wheel side brake, an electric iron shoe and the like, and has various forms, and the devices are usually automatically controlled to realize a closed (working) state by utilizing hydraulic pressure or an electromagnetic valve during hoisting operation; on the contrary, when the cart moves, the open state is achieved. Because port loading and unloading work is frequent, the cart often moves, and this kind of prevent gust device is often opened and closed, and most prevent gust device probably because of the braking device open and close not in place, braking part wearing and tearing and mechanical part warp scheduling problem cause the inefficacy, seriously influence the safe operation of equipment. For this reason, it is necessary to use a detection device to verify the validity of the anti-gust device in use.
At present detection device uses more adopts the pneumatic cylinder to promote cart side end to calculate its anti-wind anti-skidding ability through the pressure that promotes constantly, if: the invention has patent publication numbers of: CN109085006A, one end of which is fixed on a rail stop and the other end of which acts on the end face of the metal structure at one side of the cart by utilizing a hydraulic cylinder with a lifting function, and a pressure sensor is arranged in the middle of the hydraulic cylinder. The hydraulic pump provides pressure to move the hydraulic cylinder forward, once the hydraulic cylinder is pushed, the pressure sensor is used for recording the thrust at the moment, and the wind-resistant and skid-resistant capacity of the crane is further calculated. The device can only test the condition that only one crane is arranged on the running track, and cannot measure more than two cranes. In addition, because the stroke of the hydraulic cylinder is short, when a plurality of trolleys exist on the walking part of a complex crane, the trolley can only act on one trolley, the trolley is hinged with the upper metal structure, and the wind-proof and skid-resistant capability of the whole crane cannot be accurately reflected when only one trolley is pushed.
The invention has patent publication numbers of: CN109052175A artificially circular telegram to cart driving motor, when utilizing motor output torque to reach simulation wind force moment, the hoist whether takes place to remove judges whether accords with the requirement of preventing wind and skid. The invention shows that the comprehensive wind-resistant and skid-resistant capability of the brake with the wheel driving motor and various wind-resistant devices can be measured. In fact, the wind resistance of the wheel motor brake is to prevent the wheel from rolling friction and only sliding friction in typhoons or strong gusts, while the method requires the motor to overcome the resistance of the motor brake, which is related to the brake spring adjustment. Therefore, the torque output by part of the detection method is used for resisting the brake, is not the wind-resistant and skid-resistant capacity of the hoisting equipment, and has detection deviation.
The invention has patent publication numbers of: CN106226107B, utilize components such as wire rope, assembly pulley and push rod to constitute traction system, realize dragging, drawing the hoist to its atress condition is measured, obtains the anti-wind antiskid ability of hoist. Although the method can realize the wind-resistant and skid-resistant capability test of the whole crane, the mechanism spans two rails, and has larger height and length; a fixed pulley block is additionally arranged at one end of the cart, a plurality of pulley blocks are used, and a steel wire rope is complicated to wind, which brings inconvenience to the test.
