Abstract
The utility model discloses a rope release device is prevented to pulley, its characterized in that: contain bearing, weight, backup pad and location pin, the bearing housing is established at hoist pulley pivot both ends, and the weight comprises swing arm and balancing weight, and the vertical setting of swing arm is and the swing arm upper end is fixed at the bearing lower extreme, and the balancing weight is fixed at the swing arm lower extreme, and backup pad one end is fixed in the bearing side, and the location pin is on a parallel with the pivot setting of hoist pulley and the other end in the both sides backup pad is fixed respectively at location pin both ends, is obtuse angle fork setting between backup pad and the swing arm. The utility model discloses an oscillating structure for under the unexpected circumstances, wire rope also can the extrusion card circumstances of dying not appear with the pulley, avoids disconnected rope accident, life that the device has for a long time.
Description
Technical field
This utility model relates to a kind of anti-off rope device, particularly a kind of pulley anti-off rope device.
Background technology
Crane refers to many actions hoisting machinery of vertical-lift within the specific limits and horizontal carrying heavy goods.Also known as crane.Current domestic each big lifting Guangdong remy hair crane gear company limited cancellation lift heavy driving functions gradually.The work characteristics that crane gear has is to do intermittent exercise, and namely in a cycle of operation, the corresponding mechanism of the action such as feeding, migration, unloading is alternation, crane development commercially and use more and more extensive.
In the various single arm support crane of pitching luffing, the anti-off rope device of jib head fixed pulley generally has following form: 1. utilize the distance controlling between steel construction and pulley to stop de-rope；2. between steel construction, welding or bolt connect lever and stop de-rope etc..Owing to jib luffing angle when work and maintenance changes greatly, steel wire rope effectively cannot be protected by above anti-off rope device arbitrarily angled.Owing to above anti-off rope device is fixed, it is easy to occur that steel wire rope is stuck, cause rope-broken accident.
Utility model content
Technical problem to be solved in the utility model is to provide a kind of pulley anti-off rope device, and steel wire rope still can be formed good protection by it when crane luffing angle changes, it is to avoid de-rope.
For solving above-mentioned technical problem, this utility model be the technical scheme is that
A kind of pulley anti-off rope device, it is characterized in that: comprise bearing, weight, gripper shoe and location pin, described bearing holder (housing, cover) is located at whip-gin rotating shaft two ends, weight is made up of swing arm and balancing weight, swing arm is vertically arranged and swing arm upper end is fixed on bearing lower end, balancing weight is fixed on swing arm lower end, gripper shoe one end is fixed on bearing side, location pin is parallel to whip-gin rotating shaft and arranges and position pin two ends and be separately fixed at the other end of supported on both sides plate, diverges setting between gripper shoe and swing arm in obtuse angle.
Further, described gripper shoe is fan-shaped support plate.
Further, described location pin is two, is separately positioned on the two ends on fan-shaped support plate outer side edges edge.
Further, the sector corner dimension of described fan-shaped support plate is 30 ~ 45 °.
Further, between described gripper shoe and swing arm, angle is 100 ~ 120 °.
Further, described balancing weight is disc counterweight, and its weight is 300 ~ 1000g.
Further, described location pin is arranged on outside whip-gin and positions pin with pulley rotating shaft core distance slightly larger than pulley maximum radius.
Further, described location pin and pulley outermost edge spacing are 2 ~ 4mm.
This utility model compared with prior art, has the following advantages and effect: by the control of weight, keeps steady state, do not affected by luffing range of cantilever support in jib pitching amplitude changing process.Under the states such as Condition of Sudden Unloading, protection steel wire rope will not depart from the pulley groove of each pulley.Owing to adopting swinging structure so that under fortuitous event, steel wire rope occurs extruding stuck situation without with pulley, it is to avoid rope-broken accident, the service life that this device has for a long time.
Accompanying drawing explanation
