2) When the strut top crosspiece 10 passes over the supporting plate 8, the supporting plate 8 turns outwards under the action of the elasticity of the strut pull rod spring 19, the strut top 16 stops lifting and descends, the end part of the supporting plate 8 props against the strut top crosspiece 10, the strut clamping wedge 8-1 is inserted into a gap of the strut top crosspiece outer spring piece 10-1, the strut limiting plate 9 is clamped on the inner wall of the strut lower segment 1, and at the moment, the strut top 16 is supported on the strut lower segment 1 and is clamped and positioned;
3) When the strut upper joint 16 falls, the strut upper joint 16 is firstly lifted to the lever 27, one end of the lever 27 is lifted, the other end of the lever 27 presses down the locking button 25, the locking head 22 of the spring locking is downwards lifted, the reset plate 5 rotates inwards along the hinging point under the action of the elastic force of the reset plate spring 11, the reset plate 5 drives the support plate pull rod baffle 21 and the support plate pull rod 20 to pull the support plate 8 inwards until the end face of the support plate 8 is flush with the outer wall of the strut lower joint 1, and meanwhile, the reset wheel 2 at the bottom of the reset plate 5 is tilted outwards;
4) When the strut upper joint 16 is dropped, the strut upper joint crosspiece 10 pushes the reset wheel 2 back to the original position in the falling process of the strut upper joint 16, the reset plate 5 rotates along the hinge point and compresses the reset plate spring 11 to reset the lock hole 29, the lock chuck 22 retracts into the lock hole 29 under the action of the lock chuck spring 24 after the lock hole 29 is reset to lock the position of the reset plate 5, and meanwhile, the reset plate 5 pushes the support plate 8 out of the rectangular window through the support plate pull rod spring 19.
The specific operation is as follows:
when the upper strut section 16 is lifted upwards, the upper strut section cross brace 10 is lifted along with the upper strut section 16, and firstly the upper strut section cross brace 10 passes over the reset wheel 2 (before lifting, the reset wheel 2 is contracted at the inner side of the rectangular window of the lower strut section 1), the support plate shaft 4 and is propped against the back surface of the end plate of the U-shaped groove plate of the support plate 8, because the support plate 8 can rotate along the support plate shaft 4, the upper end of the support plate 8 has a support plate pull rod spring 19, and has a force which outwards pushes the upper strut section 16, but the force is small enough to push the upper strut section 16 lifted upwards, and the upper strut section cross brace 10 is pushed to rotate the support plate 8 along the shaft 4, and simultaneously compresses the support plate pull rod spring 19, so that the support plate pull rod 17, the support plate pull rod shaft 18 and the support plate pull rod 20 are closed towards the direction of the reset plate 5. The support plate pull rod 20 passes through the through hole on the reset plate 5 to move outwards and also abuts against the support plate pull rod baffle 21 to be far away from the reset plate 5, so that the support plate 8 is jacked into the rectangular window by the support column upper section transverse support 10, and the back surface of the end plate of the support plate 8 is flush with the outer wall of the support column lower section 1. The strut upper joint cross brace 10 continuously rises again and passes through the wedge-shaped support plate clamping wedge 8-1 on the support plate 8, at the moment, the support plate 8 outwards pops out under the elastic force of the support plate pull rod spring 19, at the moment, the strut upper joint 16 stops rising and descends, and the strut upper joint cross brace 10 also descends. Firstly, the upper head of the wedge-shaped support plate clamping wedge 8-1 on the support plate 8 firstly props up to the strut upper joint cross brace 10, and the strut upper joint cross brace 10 is fixedly provided with the strut upper joint cross piece outer spring piece 10-1 outside, and a sufficient gap is reserved between the strut upper joint cross piece outer spring piece and the strut upper joint cross brace, so that the support plate clamping wedge 8-1 is just inserted into a gap of the strut upper joint cross brace. The strut top 16 continues to descend down the strut clamp wedge 8-1, and the strut clamp wedge 8-1 also serves as a guide. After the prop upper section 16 is put down, the prop upper section cross brace 10 is just pressed on the U-shaped supporting end surface of the upper end of the supporting plate 8. At this time, the strut clamping wedge 8-1 ejects out the strut upper section crosspiece outer spring piece 10-1 (see fig. 3), firstly, the strut lower section 1 and the strut upper section crosspiece outer spring piece 10-1 are clamped together through the strut clamping wedge 8-1 and the strut limiting plate 9, secondly, the two sections of struts are square sleeved together and fixed in a clearance manner, and then the strut clamping wedge 8-1 is clamped between the strut upper section cross brace 10, so that the clearance is just added, and the clamping effect is also achieved. In addition, the invention is a supporting and clamping mechanism symmetrically arranged at two sides of the square sleeve, one side is provided with two supporting plate clamping wedges 8-1 positioning points, and two sides are provided with four clamping positioning points, so that the torsion between the upper section and the lower section of the support column can be well prevented.
When the work is completed and the upper section strut 16 needs to be dropped, the operation is performed in the following way: first, the upper joint 16 is lifted, the upper joint strut 10 is separated from the support plate 8, and after the upper joint strut leaves the support plate clamping wedge 8-1, the outer spring piece 10-1 of the upper joint strut springs back to the original position, so that the clamping function is released. The upper pillar section 16 continues to lift up, when the upper pillar section cross brace 10 is lifted up to the lever 27, the lever 27 rotates along the lever shaft 26, the other end of the lever 27 presses the locking button 25, simultaneously pushes the locking rod 23 downwards, compresses the locking spring 24, presses the locking head 22 out of the locking hole 29 to a certain extent, and then the locking fails. The reset plate spring 11 sleeved on the reset spring column 12 pushes the reset plate 5 to turn inwards by releasing energy, the locking rod 23 slides along the locking rod empty groove 28, when the reset plate 5 is pushed outwards by the reset plate spring 11, the Zhi Ban pull rod baffle 21 also moves along with the reset plate 5, the support plate pull rod baffle 21 pulls the support plate pull rod 20 to drive the support plate 8 to turn inwards to close to the rectangular window until the outer end surface of the support plate 8 is flush with the window of the lower support post section 1, and then the reset wheel 2 at the tail end of the reset plate 5 is just bent out of the lower support post section 1. Then the upper strut section 16 is downward, and the support plate 8 is flat with the lower strut section 1, so that the upper strut section cross brace 10 is not blocked by the support plate 8 when being downward, when the upper strut section cross brace 10 is downward to the reset wheel 2, the reset wheel 2 is pushed to rotate along the reset wheel shaft 3, the reset plate 5 is pushed to rotate along the reset plate shaft 7, the reset plate spring 11 is compressed at the upper end of the reset plate 5, when the reset wheel 2 is pressed to be flat with the lower strut section 1, the reset plate spring 11 is compressed at the upper end of the reset plate 5, at the moment, the lock clamp head 22 is exactly aligned with the lock hole 29, and the lock clamp head 22 is retracted into the lock hole 29 under the action of the lock clamp spring 24, so that the reset plate 5 is locked. And the supporting plate 8 is ejected out by the supporting plate pull rod spring 19 to restore the working initial state.
