Description

Side holding type anti-creep device

Technical Field

The utility model relates to a large-scale bank rail-mounted equipment prevent wind protection equipment technical field, especially relate to a side formula anti-creep device of holding tightly.

Background

Large equipment such as a shore bridge crane, a gantry crane and a gantry crane of a port generally operates in open air on the coast, in recent years, severe climates such as coastal typhoons, hurricanes and the like frequently occur, and in addition, the port equipment has large windward area and high equipment height, so that the equipment can bear great wind load in the severe climates. When the anti-slip force of the equipment along the track direction is not enough to resist the wind load, the equipment can accelerate and slide along the wind load direction on the track until the equipment collides with the limit baffle plate close to the equipment or arranged at the end of the track, so that the equipment is damaged, even overturns and other serious safety accidents occur. In order to prevent such accidents, the harbour site administration sets out that all shore-side working facilities must be equipped with safe and reliable wind-resistant and skid-resistant devices. The wind-proof and anti-skid devices adopted in the prior harbors mainly have three types: the anchoring type windproof and antiskid device, the pressing rail and top rail type windproof and antiskid device and the clamping rail type windproof and antiskid device.

The anchoring type wind-proof and skid-resistant device has the working principle that the anchoring device is used for fixing the equipment bolt anchor at a specified position, namely, the equipment is connected with the ground through an anchoring inserting plate, a wind-proof inhaul cable and the like so as to limit the movement of the equipment. The device has the advantages of simple structure, safety and reliability, and has the defects that the anchoring points can be only arranged at a plurality of positions along the track of the equipment, when strong wind comes, the equipment needs to be moved to the positions near the anchoring points and then fastened and anchored, the operation is complicated and inconvenient, and the equipment is difficult to be stopped and anchored in time particularly when sudden storm occurs.

The working principle of the windproof and antiskid device such as the pressure rail and the top rail is that partial self-weight of equipment is converted to act on the rail top by other auxiliary equipment, so that the friction force generated between the equipment and the top surface of the rail is increased to resist wind power. The device has the advantages of simple structure and convenient operation; the disadvantage is that only the dead weight of the equipment part can be used to increase the friction force. The device has a good anti-skid effect on common strong wind, but when the device is subjected to extreme weather, the acting wind force is far larger than the maximum friction force which can be generated by the device, and the use safety is not high.

The working principle of the rail clamping type windproof and antiskid device is that the rail clamping device is used for actively clamping two sides of the head of the rail, and wind force is resisted through friction force generated by clamping. The device has the advantages that a larger clamping force can be actively provided; the disadvantage is that the size and the arrangement space of the equipment limit, the generated active clamping force is limited, and the device is only suitable for the general strong wind condition, and the use safety is not high when the device is exposed to extreme weather.

The three types of windproof and antiskid devices are widely applied to various types of shore equipment at present, but when the equipment is attacked by extreme weather, accidents that the equipment is blown by wind, slides, collides, damages and even overturns and falls into the sea due to insufficient windproof capability or action failure of the device design often occur, the accidents not only influence the normal production operation of a port area, but also cause great property loss to the port area. At present, a safe and reliable wind-proof anti-skid device is needed for large ports and wharfs to solve the problem that equipment slips along a rail when suffering from extreme weather and tips over under the action of inertia force.
