Background technology
Along with the continuous increase of China's ports container quantity, operating efficiency and the safety requirements of harbour facilities maintenance are more and more higher.Traditional bank bridge sling upper rack pulley spindle dismounting technique uses sledgehammer and copper rod directly to knock pulley spindle end, until got by pulley spindle.In view of sling upper rack pulley spindle to knock end space narrow and small, operate very difficult, and very easily damage pulley spindle edge again in the process of knocking, even likely occur the situation of injury to personnel.During pulley spindle detachable maintaining, maintenance personal drop into many, cost is high, inefficiency.The work of harbour machinery repair and maintenance urgently improves maintenance tool further, to adapt to actual production demand, shortens maintenance cycle.
Summary of the invention
The present invention is to overcome deficiency of the prior art, a kind of provision for disengagement of bank bridge sling upper rack pulley spindle is provided, can avoid using sledgehammer and copper rod directly to knock the clumsiness dismounting mode of pulley spindle, can operating efficiency be drastically increased, in turn enhance the security of repair and maintenance person works.
The present invention for achieving the above object, be achieved through the following technical solutions, a kind of provision for disengagement of bank bridge sling upper rack pulley spindle, it is characterized in that: comprise, lower semi-circular connecting plate, fastening bolt, locate puller bolt and move back axle bolt, on described, monoblock type loop connecting fixture is formed after lower semi-circular connecting plate fastens, on described, lower semi-circular connecting plate two side ends is provided with engaging lug, described engaging lug is provided with connecting hole, described connecting hole is connected with fastening bolt, on described, the sidewall of lower semi-circular connecting plate is arranged with location and holds out against screwed hole, described location holds out against on screwed hole and is bolted with location puller bolt, on described, lower semi-circular connecting plate and the perpendicular position of engaging lug horizontal line are respectively equipped with moves back axle bolt screw, the described axle bolt screw that moves back is bolted with and moves back axle bolt.
Described engaging lug is respectively equipped with 1-2 screwed hole.
Described location holds out against screwed hole, and to be separately positioned on monoblock type loop connecting fixture cross centre line be 45 ° of angular position, and it is four that location holds out against screwed hole quantity.
The axle bolt screwhole position that moves back of described upper and lower semicircle connecting plate is provided with reinforcement projection.
Connecting hole on described engaging lug is set to screwed hole and is spirally connected with fastening bolt on the left of it, and on the right side of engaging lug, connecting hole is the via hole that fastening bolt passes.
Beneficial effect: the present invention compared with prior art, use the provision for disengagement of bank bridge sling upper rack pulley spindle, both solved the difficulty that conventional method sledgehammer, copper rod directly knock pulley spindle dismounting, and drastically increased operating efficiency, in turn enhance the security of repair and maintenance person works.

Detailed description of the invention
Below in conjunction with preferred embodiment, to according to detailed description of the invention provided by the invention, details are as follows:
Embodiment
Refer to accompanying drawing, present embodiments provide a kind of provision for disengagement of bank bridge sling upper rack pulley spindle, comprise, lower semi-circular connecting plate 1, 2, fastening bolt 3, locate puller bolt 4 and move back axle bolt 5, on described, monoblock type loop connecting fixture is formed after lower semi-circular connecting plate fastens, on described, lower semi-circular connecting plate two side ends is provided with engaging lug 6, described engaging lug is provided with connecting hole, described connecting hole is connected with fastening bolt, connecting hole on described engaging lug is set to screwed hole and is spirally connected with fastening bolt on the left of it, on the right side of engaging lug, connecting hole is the via hole that fastening bolt passes, that is, link bolt hole tapping on the left of first circular connecting plate, right side link bolt hole is smooth without screw thread, and on the left of lower semi-circular connecting plate, link bolt hole is smooth without screw thread, right side link bolt hole tapping.Described engaging lug is respectively equipped with 1-2 screwed hole.The sidewall of described upper and lower semicircle connecting plate is arranged with location and holds out against screwed hole 7, described location holds out against on screwed hole and is bolted with location puller bolt 4, described location holds out against screwed hole, and to be separately positioned on monoblock type loop connecting fixture cross centre line be 45 ° of angular position, and it is four that location holds out against screwed hole quantity.Described upper and lower semicircle connecting plate and the perpendicular position of engaging lug horizontal line are respectively equipped with moves back axle bolt screw, described in move back axle bolt screw and be bolted with and move back axle bolt 5.The axle bolt screwhole position that moves back of described upper and lower semicircle connecting plate is provided with reinforcement projection 8, can strengthen the intensity of provision for disengagement.
Upper and lower semicircle connecting plate edge does chamfered, polishes smooth, to ensure to scratch pulley spindle.
The course of work
Refer to accompanying drawing 2, after bank bridge sling upper rack places ground, hoist rope is made to be slack rope state, pull down pulley spindle axle clamping plate and hubcap, pulley spindle 9 is made to be in not by pulley Action of Gravity Field state with little fork truck by withholding, with fastening bolt, upper semi-circle connecting plate and lower half circle connecting plate are fastened on pulley spindle, with location puller bolt by upper semi-circle connecting plate, lower half circle connecting plate and pulley spindle position and hold out against, prevent connecting plate and pulley spindle from producing relative sliding, withstand on bank bridge sling upper rack side plate (reinforcement gusset) with moving back axle bolt, axle bolt is moved back to screwing direction synchronous axial system with spanner, pulley spindle slowly will exit added and pulley axis hole, then with fork truck, pulley is hung out from sling upper rack, other three pulley spindles can by like manner dismantling.The provision for disengagement of bank bridge sling upper rack pulley spindle had both solved the difficulty that conventional method sledgehammer, copper rod directly knock pulley spindle dismounting, drastically increased operating efficiency, in turn enhanced the security of repair and maintenance person works.
