Safety bar assembly 1 mainly comprises anti-drop rod 6, rebound 7, otic placode 8, anti-drop rod 6 is installed with above rebound 7, usually anti-drop rod 6 is arranged on the centre of rebound 7, below rebound 7, is installed with the both sides that 2 otic placodes be parallel to each other, 8,2 otic placodes 8 are positioned at anti-drop rod.Anti-drop rod 6, otic placode 8 and rebound 7 are fixedly connected with and adopt welding process to be connected.

The otic placode 8 of safety bar assembly 1 is corresponding with the ear seat 10 of lifting assembly 2, connected by bearing pin 4, bearing pin 4 is provided with torque spring 3, in the termination, two ends of torque spring 3, one end is limited to the base 11 of lifting assembly 2, and the other end is limited to the rebound 7 of safety bar assembly 1.The end radial direction of bearing pin 4 is provided with spring cotter 5 by bearing pin 4 axial limiting; Anti-drop rod 6 in safety bar assembly 1 and gib head 20 contact outside lifting suspension hook plate 9 in assembly 2, safety bar assembly 1 one restoring forces are given under the effect of torque spring 3, make anti-drop rod 6 tightly can touch the suspension hook of suspension hook plate 9, anti-drop rod 6 and suspension hook form a closed loop.Be provided with, the upper end of anti-drop rod 6 higher than suspension hook plate 9, should be convenient to hoisting rope and enter in suspension hook.When the external force acting on anti-drop rod 6 upper end can overcome the resistance of torque spring 3, anti-drop rod 6 is swung for axle with bearing pin 4, the closed loop between anti-drop rod 6 and suspension hook is opened.

See accompanying drawing 2.Application the utility model implements lifting operation, should be fixedly mounted on lifting object 19 by the high-altitude safe suspension hook of terrestrial operation on ground.Base plate 11 of the present utility model there is bolt hole, by bolt 17, base plate 11 is fixedly connected with the connecting panel 18 of lifting object 19.

See accompanying drawing 3,4.Application the utility model implements lifting operation, and the Current Collector Sleave used mainly comprises suspension ring 13, hoisting rope 12, hauling rope 15 etc., and suspension ring 13 can be mounted on the hook of weight-lifting equipment; Suspension ring 13 are connected with 2 hoisting ropes 12, and need the hoisting rope 12 mounted with suspension hook of the present utility model to be ring-type, ring-type hoisting rope 12 is connected with hauling rope 15, and the quantity of usual hauling rope 15 is 2.Hauling rope 15 is handled by surface personnel, and 2 hauling ropes 15, centered by hoisting rope 12, open certain angle to both sides.

Embodiment 1

Tail walking beam 14 dismantles from beam pumper by application the utility model, and concrete job step is as follows:

First, by workman, hoisting rope 12 one end of Current Collector Sleave is articulated on the suspension ring of tail walking beam 14 front end; The hook mounting suspension ring 13 of lifting appliance;

Then, operation lifting appliance, ground staff handles hauling rope 15, the other end of hoisting rope 12 is entangled the upper end of anti-drop rod 6; Continue to handle hauling rope 15 and apply downward pulling force to hoisting rope 12, hoisting rope 12 pulls anti-drop rod 6 with bearing pin 4 for axis rotation, and compression torque spring 3 rotates, and occurs gap between anti-drop rod 6 and suspension hook, the suspension hook that hoisting rope 12 enters suspension hook plate 9 downwards along anti-drop rod 6 is inner, realizes mounting; Unclamp hauling rope 15, under the effect of torque spring 3, anti-drop rod 6 return, anti-drop rod 6 recovers closed loop with the suspension hook of suspension hook plate 9, and hoisting rope 12 can not be deviate from from the suspension hook of suspension hook plate 9;

Afterwards, remove the connection of tail walking beam 14 and walking beam 16, tail walking beam 14 can remove by operation lifting appliance.

Embodiment 2

Tail walking beam 14 is installed to walking beam 16 afterbody of beam pumper by application the utility model, and concrete job step is as follows:

First, mounted by the suspension ring of hoisting rope 12 one end of Current Collector Sleave and tail walking beam 14 front end, the other end being provided with hauling rope 15 is articulated on the hook of suspension hook plate 9; The hook mounting suspension ring 13 of lifting appliance;

Then, tail walking beam 14 is sling by operation lifting appliance, is connected by the afterbody of the front end of tail walking beam 14 with walking beam on pumping units 16;

Afterwards, ground staff handles hauling rope 15, oblique below to hoisting rope 12 applies pulling force, pull anti-drop rod 6 backward, safety bar assembly 1 compresses torque spring 3 and rotates, and occurs gap between safety bar 1 and suspension hook plate 9, when the anglec of rotation is enough large (as shown in phantom in Figure 1), hoisting rope 12 skids off along the suspension hook of anti-drop rod 6 from suspension hook plate 9, realizes the unhook of hoisting rope 12;

Finally, by workman, hoisting rope 12 one end hanging over tail walking beam 14 front end is unloaded, complete lifting operation.

The high-altitude safe suspension hook of the utility model terrestrial operation has rational in infrastructure, simple, is realizing upper air installing simple operation, safe and reliable, and rope enters automatic blocking after hook, and rope such as not easily to break off relations at the feature.The utility model is not limited only to the lifting operation of tail walking beam in beam pumper involved in embodiment, is also applicable to the dismounting of other similar upper air installing things, installation exercise.

It should be noted that above-described embodiment is example and unrestricted the present invention, those skilled in the art can design a lot of alternate embodiment and not depart from the right of this patent.
