In the specific setting, a bolt groove 505 is provided on the top of the trolley extension arm 501, and a protruding bolt corresponding to the position of the trolley extension arm bolt groove is provided on the lower side wall of the column base section 2, through which the counterweight is further fixed. trolley. the

The hoisting mechanism of the expansion joint 3 is set, and the hoisting mechanism includes: a winch shaft 601 with two winches, the winch shaft is mounted on the installation base 504 at the front end of the counterweight trolley boom 501 through bearings, behind the winch shaft The end is connected with a handwheel 603, and one end of the lifting braided sling 602 is fixedly connected to the winch shaft 601 between the two capstans, and the other end is fixedly connected to the braided sling fixing rod 302 at the bottom of the expansion joint 3, and the middle part of the braided sling 602 Go around on the fixed pulley provided on the upper part of the outer wall of the base section 2 of the self-supporting column. the

The double locking mechanism of the telescopic joint 3 is set, the first locking mechanism includes: a pawl seat 701 rigidly connected to the front end of the winch shaft 601 through a key, and two pawls 702 are symmetrically connected to the pawl seat through a pin shaft and a torsion spring On the installation base of the front end of the trolley arm, a ratchet brake seat 703 is connected by bolts, and the rear end face of the ratchet wheel 704 that cooperates with the two ratchets 702 is in contact with the base surface of the inner cavity of the ratchet brake seat 703. Form the ratchet pressure plate 705 in surface contact, the central hole of the ratchet pressure plate is threadedly connected with the brake handle 706 and locked by the lock nut 707, and the outer circumference of the ratchet pressure plate is threaded with the inner cavity side wall of the ratchet brake seat. the

The second locking mechanism includes: protruding ratchets 304 are fixed at equal intervals from top to bottom on one side of the telescopic joint 3, and ratchet mounting ears 202 are provided on the upper outer wall of the column base section 2, which are connected with the ratchets. The matching ratchet bar 203 is installed on the ratchet bar mounting ear 202 through a pin shaft and a torsion spring, and a part of the ratchet bar 203 extends from the square hole at the ratchet bar mounting ear of the column base section into the ratchet teeth of the column base section and the outer wall of the expansion joint. 304 form a fit. Every time the expansion joint protrudes 50mm, a ratchet lock is realized to ensure that the suspension of the expansion joint is stable during hoisting and personnel operations. the

The outer walls of the upper four sides of the column base section 2 are provided with deep groove ball bearings 201, and a part of each deep groove ball bearing extends into the inner cavity of the column base section, and the shaft of each deep groove ball bearing is fixed on the outer wall of the column base section in a lateral direction; Bearings 303 are also provided on the inner walls of the lower four sides of the section 3, and a part of each bearing 303 extends out of the telescopic section, and the shafts of each bearing are laterally fixed on the inner wall of the telescopic section. the

In a specific application, when it is necessary to lift the bucket basket at 4 o'clock, turn the hand wheel 603 in the forward direction, the hand wheel drives the winch shaft 601 to rotate and wind the sling 602, and the sling drives the expansion joint 3 to rise in the column base section 2, because the column base section The friction between 2 and telescopic joint 3 is rolling friction (the function of deep groove ball bearing 201 and bearing 303), so the lifting force does not need to be large. With the function of ratchet and pawl, the expansion joint can stay at any height. At this time, the ratchet pressure plate 705 and the brake handle 706 are locked together by the lock nut 707, and the ratchet pressure plate 705 is locked by the thread on its outer circumference. Tighten in the ratchet brake seat 703, the ratchet pressure plate 705 and the ratchet brake seat 703 lock the ratchet in the inner cavity of the ratchet brake seat 703 from the two end faces of the ratchet wheel 704, and the ratchet wheel 704 controls the ratchet seat 701 to only rotate in one direction , since the ratchet seat 701 is rigidly connected to the winch shaft 601, the hand wheel 603 can only rotate in the forward direction, ensuring that the telescopic joint 3 can stay at any height when it rises. In addition, since the ratchets 203 on the upper part of the column base block the ratchets 304 on the outer wall of the expansion joint, it is ensured that the expansion joint can only rise in one direction and cannot fall, which has played a double role in ensuring the safety of the operators. When the bucket basket needs to be lowered, the ratchet bar 203 first releases the limit of the ratchet 304, and then slightly reverses the brake handle 706. At this time, the ratchet pressure plate 705 also slightly withdraws from the ratchet brake seat 703, and the ratchet pressure plate 705 reduces the pressure on the ratchet 704, so the ratchet 704 can idle in the ratchet brake seat 703. Due to the effect of gravity, the bucket basket 4 and the telescopic joint 3 descend, driving the winch shaft 601 to reverse, and the winch shaft drives the ratchet seat and ratchet. Claws and ratchets drive the ratchet to rotate idly. When the telescopic joint needs to be stopped, the brake handle 706 only needs to be rotated forward to lock the ratchet in the ratchet brake seat. the
