One end of the sliding columns 66 extending out of the sliding sleeve 6 is further fixedly connected with a pressure rod 662, the lower side of the sliding sleeve 6 is further fixedly connected with a connecting ring 67, and the connecting ring 67 can be connected with a safety belt.
When the sliding sleeve is used, a worker firstly adopts two safety belts, one end of each safety belt is connected with the connecting ring 67 of the sliding sleeve 6, the other end of each safety belt is connected with the corresponding sliding sleeve, the sliding columns 66 can be driven to move towards the sliding sleeves 6 by pressing the pressure rods 662 towards the inside of the sliding sleeves 6 through fingers, so that the spline shafts 655 can be driven to move towards the direction away from the rotating columns 651 through the swinging of the connecting columns 661, and the spline shafts 655 can be separated from the spline grooves 654, at the moment, although the swinging plates 652 on one sides of the rotating columns 651 are kept in a horizontal state and inserted in the sliding grooves 62 under the normal state of the torsion spring, the rotating columns 651 can be forced to rotate, then the sliding sleeves 6 slide upwards along the upright columns 4, when the sliding sleeves 6 meet the positions of the supporting columns 3, the swinging plates 652 abut against the supporting columns 3, the swinging plates 652 can be allowed to move towards the positions through the rotating columns 651, so, the sliding of the sliding sleeve 6 is facilitated, and then, when the supporting column 3 passes through the sliding groove 62 of the sliding groove 62, the rotating column 651 drives the rotating plate to rotate to be horizontally inserted into the slot again through the action of the torsion spring 653; when the hands of the worker are separated from the sliding sleeve 6 to work or the hands of the worker fall off the sliding sleeve 6 due to accidents, the outer end of the sliding column 66 loses pressure, the push spring two 656 pushes the spline shaft 655 to be directly inserted into the spline groove 654 of the rotary column 651 through the push spring force, the rotary column 651 is locked, so that the rotary column 651 cannot rotate, and the swinging plate 652 is also fixed in the horizontal state in the slot because the swinging rod can be kept horizontally inserted into the sliding groove 62 by the torsion spring 653 under the normal state, when the spline shaft 655 is inserted into the spline groove 654 of the rotary column 651 and the rotary column 651 is locked, at this time, because the swinging plate 652 blocks the sliding groove 62, the supporting columns 3 cannot cross the sliding groove 62, the sliding sleeve 6 can only slide at the distance between the adjacent supporting columns 3 on the upright column 4, and further when the worker falls off the hands due to misoperation, the two sliding sleeves 6 directly lock the worker, so that the worker cannot,
referring back to fig. 2 and 3, the outer side of the sliding sleeve 6 is further fixedly connected with a hand guard plate 68, a holding groove 681 convenient for a user to wear the hand is arranged between the sliding sleeve 6 and the hand guard plate 68, and the hand guard plate 68 and the outer side of the sliding sleeve 6 are fixedly connected with an anti-slip layer. Still the rigid coupling has supplementary ring 69 on the sliding sleeve 6, is provided with connecting link 691 on the supplementary ring 69, and the connecting link hangs the knot with supplementary ring 69 to be connected, and the one end rigid coupling that connecting link 691 kept away from supplementary ring 69 is equipped with the lantern ring 692 that can locate the staff wrist portion. Before the staff climbing, the staff also can be according to the demand with the lantern ring 692 direct cover locate the wrist portion, then the hand is worn to establish and grips groove 681 and hold tightly in sliding sleeve 6, scrambles again, is connected with the staff wrist portion through go-between 67, can reduce the probability that the staff hand breaks away from sliding sleeve 6, in addition, adopts the skid resistant course can also increase the frictional force of staff hand and sliding sleeve 6, reduces the probability of skidding.
The implementation principle of the embodiment is as follows: when the sliding sleeve is used, a worker firstly adopts two safety belts, one end of each safety belt is connected with the connecting ring 67 of the sliding sleeve 6, the other end of each safety belt is connected with the connecting ring 67 of the sliding sleeve 6, when the worker climbs, the worker respectively holds the two sliding sleeves 6 by two hands, then the fingers tend to the inside of the sliding sleeves 6 to press one end of each sliding column 66 extending out of the sliding sleeves 6, so that the sliding columns 66 tend to move towards the inside of the sliding sleeves 6, the spline shaft 655 can be driven to move towards the direction away from the rotating column 651 through the swinging of the connecting column 661, the spline shaft 655 can be separated from the spline groove 654, at the moment, although the swinging plate 652 on one side of the rotating column 651 is kept to be horizontally inserted in the sliding groove 62 under the normal state of the torsion spring 653, the rotating column 651 can be rotated after being stressed, then the sliding sleeves 6 are upwards along the upright column 4, when, so that the supporting column 3 penetrates through the sliding groove 62 of the sliding sleeve 6, thereby facilitating the sliding of the sliding sleeve 6, then, when the supporting column 3 passes through the sliding groove 62 of the sliding groove 62, the rotating column 651 drives the rotating plate to rotate to the horizontal direction through the action of the torsion spring 653 to be inserted into the slot, after sliding to a proper distance, the pressing block 633 on the side wall of the sliding sleeve 6 is pressed by fingers, the first tooth block 631 is pushed to slide towards the upright post 4, thereby the first tooth block 631 is inserted into the first tooth groove 42 of the upright post 4, at this time, the upright post 4 and the sliding sleeve 6 are fixed with the first tooth groove 42 through the first tooth block 631, thereby preventing the sliding sleeve 6 from sliding, at this time, an operator can use the power of the sliding sleeve 6 to climb the pedal beam 2, when the pedal beam 2 of the worker is stable, the pressing block 633 is released, the first push spring 632 can drag the first tooth block 631 to be separated from the first tooth groove 42, the sliding sleeve, the staff can climb through pedal crossbeam 2 once more, can realize the staff from reciprocating up and down along the cat ladder if.
When the hands of the worker are separated from the sliding sleeve 6 to work or the hands of the worker fall off the sliding sleeve 6 due to accidents, the outer end of the sliding column 66 loses pressure, the push spring two 656 pushes the two spline shafts 655 to be directly inserted into the spline grooves 654 of the rotary column 651 through the force of the push spring, the rotary column 651 is locked, so that the rotary column 651 cannot rotate, and the swinging plate 652 is also fixed in the horizontal state in the slot because the swinging rod can be kept in the horizontal state to be inserted into the sliding groove 62 by the torsion spring 653 under the normal state, when the spline shafts 655 are inserted into the spline grooves 654 of the rotary column 651, the swinging plate 652 cannot cross the sliding groove 62, so that the sliding sleeve 6 can only slide at the distance between the adjacent supporting columns 3 on the upright column at the moment, and further when the worker falls off the hands due to misoperation, the two sliding sleeves 6 directly lock the worker, so that the worker cannot continuously fall down, the life safety of the working personnel is effectively protected.
The embodiments of the present invention are preferred embodiments of the present invention, and the scope of the present invention is not limited by these embodiments, so: all equivalent changes made according to the structure, shape and principle of the invention are covered by the protection scope of the invention.
