Stop pin 44 can be locked in locking circle body 41 and baffle plate 3 on pipe link 1, and then can weigh 5 degree of freedom on the length direction of pipe link 1 by baffle plate 3 limiting balances.
As preferably or alternatively embodiment of one, one end that stop pin 44 is arranged in the two ends outside knock hole 42 and locking through hole 43 is provided with the anticreep pin being detachably fixedly connected with stop pin 44, and in two ends, the radial dimension of the other end is greater than the internal diameter size that locks through hole 43.
The said structure not only installation exercise of stop pin 44 is comparatively simple, and can effectively avoid stop pin 44 to deviate from from locking through hole 43.
Certainly, stop pin 44 can be also interference fit with knock hole 42 and locking through hole 43.Or every one end that stop pin 44 is arranged in knock hole 42 and the two ends of locking outside through hole 43 is all detachably fixedly connected with the technical scheme of anticreep pin and also can avoids stop pin 44 to deviate from from knock hole 42 and locking through hole 43.
As preferably or alternatively embodiment of one, pipe link 1 is circular rod member, and its circumferential exterior surface is also fixedly installed sliding rail 11, the inwall of the inwall of the described installation through hole of baffle plate 3 and locking circle body 41 is provided with guide groove, sliding rail 11 is embedded in guide groove, and the length direction of sliding rail 11 is consistent with the length direction of pipe link 1.
Sliding rail 11 can limit baffle plate 3 and the relative position of pipe link 1 in the rotation direction of pipe link 1 with the fit structure that guide groove forms.When locking latch pin 44, the fit structure that can form by sliding rail 11 and guide groove in pipe link 1 rotation process does not drive baffle plate 3 and locking circle body 41 rotate.
As preferably or alternatively embodiment of one, in the part that counterbalanced weight 5 and baffle plate 3 connect, be also provided with latched position mark 55 and unlocked position mark 56, on baffle plate 3, be provided with position arrow 31.
In the circumferential direction of pipe link 1, baffle plate 3 turns to position arrow 31 while making position that fixture block 2 aligns with draw-in groove 51 with pipe link 1 and points to latched position mark 55.
In the circumferential direction of pipe link 1, baffle plate 3 with pipe link 1 turn to make position that fixture block 2 aligns with draw-in groove 51 away from position time position arrow 31 point to unlocked position mark 56.
The position arrow 31 arranging on baffle plate 3 has indicative function to baffle plate 3, pipe link 1 and the position of fixture block 2 in the rotation direction of pipe link 1.Identify 56 separately and position relationship between position arrow 31 by observation latched position mark 55 and unlocked position, operating personal can be judged the position relationship between fixture block 2 and draw-in groove 51, and then is conducive to fast counterbalanced weight 5 and fixture block 2 be put in place safely.
As preferably or alternatively embodiment of one, one end that pipe link 1 deviates from counterbalanced weight 5 is also fixedly connected with connecting panel 12, on connecting panel 12, is provided with and articulates through hole.
Can use the device of steel cable, a suspension hook or similar suspension hook to articulate mutually with articulating through hole, thereby realize the lifting operation to pipe link 1 and counterbalanced weight 5.
As preferably or alternatively embodiment of one, the number of counterbalanced weight 5 is at least two, and two adjacent counterbalanceds weight 5 connect each other, and the number of the locking through hole 43 arranging on pipe link 1 is identical with the number of counterbalanced weight 5.On the length direction of pipe link 1, baffle plate 3 is pressed in counterbalanced weight 5 on a counterbalanced weight 5 away from fixture block 2.
In change the utility model, the position of latching device 4 on the length direction of pipe link 1 can lift the counterbalanced weight 5 of various combination.The number of locking through hole 43 can be set according to the length of the weight of the needed counterbalanced weight 5 of reality and pipe link 1, no matter on pipe link 1, be plugged with several counterbalanceds weight 5, baffle plate 3 is pressed in counterbalanced weight 5 away from a counterbalanced weight 5 of fixture block 2 time, the knock hole 42 of locking circle body 41 always aligns with the locking through hole 43 arranging on a pipe link 1, with locking latch pin 44.
As preferably or alternatively embodiment of one, in two counterbalanceds weight 5 that connect, on a counterbalanced weight 5, be provided with at least one stop bit projection 57, stop bit projection 57 is protruded towards the direction that deviates from fixture block 2, and each stop bit projection 57 be embedded in another counterbalanceds weight 5 of this counterbalanced weight 5 butts on stop bit groove in.
Stop bit projection 57 can avoid two counterbalanceds weight 5 that connect, in the rotation direction of pipe link 1, relative displacement occurs with the fit structure of stop bit groove.
The optimal technical scheme of concentrating explanation the utility model to provide below in conjunction with Fig. 1～Fig. 5:
Pipe link 1 upper end connecting panel 12 articulate through hole in order to connecting shackle, the middle through-hole 50 that when use, the fixture block of lower end of the present utility model 2 is inserted into counterbalanced weight 5 to leg-of-mutton fixture block (being called for short: corner block) 2 bottom surfaces flush (the position arrow 31 of baffle plate 3 points to unlocked position mark 56 UNLOCK marks) with counterbalanced weight 5 bottom surfaces, center, then pipe link 1 is risen to along 60 ° of its circumferential left-hand revolutions and along its length can not move till (it is that LOCK identifies that the position arrow 31 of baffle plate 3 points to latched position mark 55).Now, suspender is locked by the draw-in groove 51 between leg-of-mutton fixture block 2 and counterbalanced weight 5, avoids radial motion, and then fixing and locking device 4 is to prevent moving axially of counterbalanced weight 5.Unloading process is completely contrary.
As shown in Figure 1, the upper end of pipe link 1 is welded with connecting panel (be specially slab) with circular hole 12, a leg-of-mutton fixture block 2 of lower end welding, middle latching device 4 can be on pipe link 1 crank motion, fix by stop pin 44 and anticreep pin.In the time that latching device 4 is fixed at first (position shown in Fig. 1), can lift a counterbalanced weight 5, in the time that latching device 4 is fixed on second point, can lift two counterbalanceds weight 5.
As shown in Figure 2, when the utility model is placed into the middle through-hole 50 of counterbalanced weight 5, it is that UNLOCK mark and both shape directions are consistent that the position arrow 31 of baffle plate 3 points to unlocked position mark 56, triangle fixture block 2 flushes with counterbalanced weight 5 bottom surfaces, center, be rotatably connected 160 °, bar and upwards mention, now latching device 4 can move axially on center link, and it is UNLOCK mark that the position arrow 31 of baffle plate 3 points to unlocked position mark 56.
In Fig. 3, illustrated that triangle fixture block 2 does not enter the state in counterbalanced weight 5 bottom surface middle through-holes draw-in groove 51 around, illustrated that triangle fixture block 2 has entered in counterbalanced weight 5 bottom surface middle through-holes draw-in groove 51 around in Fig. 4, fixture block 2 is in limited state; Now, latching device 4 locked flapper 3 simultaneously, it is LOCK mark that the position arrow 31 of baffle plate 3 points to latched position mark 55.
