The specific embodiment
Existing insulator is as shown in Fig. 6 ~ 7: the upper end of insulator 12 has columniform wiring cap 13, is symmetrically arranged with the touch block 16 of two evaginations on wiring cap.
The embodiment of insulator suspender is as shown in Fig. 1 ~ 8: comprise suspender body 4, the upper end of suspender body is fixed with the suspension ring 3 for being connected with corresponding lifting appliance, suspension ring are installed on suspender body by swivel nut 2, on suspender body, be provided with knock hole 20, knock hole in use rotational positioning is set on the wiring cap of insulator upper end, the below of suspender body is installed with symmetrically arranged two supporters 14, two supporters around the circumferential arrangement of knock hole in the periphery of knock hole, two supporters circumferentially between be provided with the circular gap 21 that length is greater than the axial length of touch block, between each supporter and suspender body, be provided with for corresponding wiring plug of tobacco fore-and-aft direction and rotate the endplay 22 screwing in, during use, supporter can be by rear to front rotation direction touch block.On suspender body and supporter, be provided with at each touch block and rotate and screw in the touch block stop gear that stops each touch block to screw out with the spacing cooperation of corresponding touch block after corresponding endplay in corresponding endplay, touch block stop gear comprises the stop block 15 being arranged in each endplay, on stop block, there is block direction forward, for the stopping surface coordinating with corresponding touch block rear end block, the upper end of stop block and suspender body are fixedly installed, lower end and the supporter of stop block are fixedly installed, thereby each stop block is respectively used to coordinate restriction supporter to continue to rotate forward with corresponding touch block rear end block, touch block stop gear also comprises the locking position limiting structure 1 with the corresponding setting of each touch block, locking position limiting structure comprises the mount pad 5 that is installed in suspender body upper end, in mount pad, be provided with the pilot hole that axis extends along the vertical direction, in pilot hole, slide-and-guide is coated with position-limited lever 7, position-limited lever has the locking position coordinating with corresponding touch block front end block away from mount pad motion and the solution lock-bit that gets out of the way corresponding touch block front end towards mount pad motion, on supporter, be provided with for supply the spacing hole of position-limited lever plug-in mounting when separating lock-bit at position-limited lever, the lower end of position-limited lever arranges external diameter and becomes gradually from the bottom to top large, and for the ball head structure 7-1 that leads and coordinate with spacing hole.On the hole wall of pilot hole, be provided with bearing pin chute, on position-limited lever, be radially coated with bearing pin 8, one end guiding of bearing pin is slided and is plugged in bearing pin chute, bearing pin chute comprises the vertical slot section 25 that bearing of trend extends along the vertical direction and is communicated with vertical slot section lower end and translot section 26 that bearing of trend circumferentially extends along pilot hole, translot section is provided with the positioning groove section 27 of extending upward away from one end of vertical slot section, is top-loaded with to bearing pin, position-limited lever and applies the retracing spring 6 of directive effect power upward between bearing pin and mount pad.The upper end of position-limited lever is provided with to position-limited lever and applies the handle 10 of directive effect power down, is provided with the push rod 11 coordinating with position-limited lever pushing tow on handle.In figure, part 9 represents the fixing lock screw of bearing pin.
In use, first the knock hole turning set of suspender body is loaded on the wiring cap of insulator upper end, now in the circular gap of the touch block on insulator between two supporters, rotate suspender body, touch block on insulator is screwed in the endplay between supporter and suspender body, until stop block only coordinates with a side block of touch block, then press down handle, hand propelled position-limited lever is moved down, now Xiao Zhou slides in the vertical slot section of bearing pin chute, after the lower end of position-limited lever is inserted in the spacing hole on supporter, rotary spacing bar, make pin slide to the translot section of bearing pin chute, application force lower bearing pin at retracing spring is finally positioned in the positioning groove section of bearing pin chute, position-limited lever is in locking position, now position-limited lever also coordinates with the opposite side block of touch block, touch block is located between position-limited lever and stop block, so just realized the bilateral restriction of butted line plate, insulator is blocked firmly, when corresponding lifting appliance lifting, supporter coordinates and insulator is sling with the bottom bracketing of touch block, knock hole coordinates with the location of wiring cap and has guaranteed that insulator deflection can not occur in handling process, rock.When needs insulator is separated with suspender, rotation pin is to the vertical slot section of bearing pin chute, and under the application force of retracing spring, bearing pin drives on position-limited lever and moves to solution lock-bit, and now position-limited lever gets out of the way touch block, and reversion supporter can be realized the separated of supporter and touch block.While having guaranteed that by clamping of butted line plate even lifting rope relaxes, insulator can not depart from suspender yet; Stop block and supporter, suspender body are wholely set, and the line plate block that can achieve a butt joint can also be realized the effect that increases supporter and suspender body construction intensity; The locking position limiting structure of position-limited lever, retracing spring formula can be realized the quick switching of locking and unlocking function.
In other embodiments of the invention: stop block and locking position limiting structure can also be replaced by limit shaft or a bolt that runs through supporter, suspender body and touch block; Retracing spring can also be mounted between position-limited lever and mount pad, and retracing spring can not established yet certainly, now can by the form of hand reset, realize the reset of position-limited lever, and when there is no retracing spring, bearing pin chute can only comprise a vertical slot section; Certainly supporter can also rotate and be arranged on suspender body; Stop block can also be fixedly arranged on separately on supporter or suspender body; Suspension ring can also be replaced by lifting hole(eyelet), suspension hook or other hoisting structure; The spacing hole installing for position-limited lever lower end guiding can not establish yet, and now only relies on the confining force of mount pad to keep position-limited lever, and ball head structure can also be replaced by conehead structure certainly; Positioning groove section can also not established, and pin can be limited in translot section.
