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.

立柱基节2的上部四边外壁设有深沟球轴承201,各深沟球轴承的一部分延伸入立柱基节的内腔,并且各深沟球轴承的轴横向固定在立柱基节的外壁;伸缩节3的下部四边内壁同样设有轴承303,各轴承303的一部分延伸出伸缩节的外部,并且各轴承的轴横向固定在伸缩节的内壁。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 laterally; 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.

具体应用中,当需要起升斗篮时,正向转动手轮603,手轮带动绞盘轴601转动并缠绕起升编织吊带602,吊带驱动伸缩节3在立柱基节2内上升,由于立柱基节2与伸缩节3之间的摩擦为滚动摩擦(深沟球轴承201与轴承303的作用),所以起升力并不需要多大,当伸缩节3上升至指定高度后,停止转动手轮603,由于棘轮、棘爪的作用,伸缩节可停留在任意高度,此时,棘轮压盘705与制动手柄706之间通过锁紧螺母707锁紧为一体,而棘轮压盘705通过其外圆周的螺纹拧紧在棘轮刹车座703内,棘轮压盘705与棘轮刹车座703从棘轮704的两个端面将棘轮锁死在棘轮刹车座703的内腔中,棘轮704控制棘爪座701只能单向转动,由于棘爪座701刚性连接在绞盘轴601上,因此手轮603只能正向转动,确保伸缩节3在上升时可停留在任意高度。另外,由于立柱基节上部的棘条203卡住伸缩节外壁的棘齿304,确保伸缩节只能单向上升,不可以下落,对作业人员的安全起到了双重保障的作用。当需要将斗篮下降时,首先解除棘条203对棘齿304的限位,然后稍微反向转动制动手柄706,此时棘轮压盘705也略微从棘轮刹车座703内退出一点,棘轮压盘705对棘轮704的压力减小,因此棘轮704可以在棘轮刹车座703内空转,由于重 力的作用,斗篮与伸缩节3下降,带动绞盘轴601反转,绞盘轴带动棘爪座和棘爪、棘爪带动棘轮空转,当需要将伸缩节停止时,只需正向转动制动手柄706,将棘轮锁死在棘轮刹车座内即可。In a specific application, when the bucket basket needs to be lifted, turn the handwheel 603 in the forward direction, the handwheel drives the winch shaft 601 to rotate and wind the lifting braided sling 602, and the sling drives the expansion joint 3 to rise in the column base section 2, because the column base The friction between the joint 2 and the expansion joint 3 is rolling friction (the effect of the deep groove ball bearing 201 and the bearing 303), so the lifting force does not need to be large. When the expansion joint 3 rises to the specified height, stop turning the handwheel 603, Due to the effect of the 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 outer circumference of the ratchet plate 705. The thread is tightened 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 pawl seat 701 to only one-way Rotate, because the pawl seat 701 is rigidly connected on the capstan shaft 601, so the handwheel 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 and the expansion joint 3 descend, driving the winch shaft 601 to reverse, and the winch shaft drives the ratchet seat and the ratchet 1. The ratchet drives 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.
