In which like parts are designated by like reference numerals. It should be noted that the terms "front," "back," "left," "right," "upper" and "lower" used in the following description refer to directions in the drawings, and the terms "bottom" and "top," "inner" and "outer" refer to directions toward and away from, respectively, the geometric center of a particular component.

The utility model provides a safety device of double-deck derrick of formula of climbing in elevator well trackless in turn, as shown in fig. 2, include with cage welded fastening's hollow lag 1 with arrange the gliding locking axle 11 of hollow lag 1 in, the one end of locking axle 11 can insert to arrange in the reservation mouth of elevator well inner wall. The welding of the one end that hollow lag 1 kept away from elevator well inner wall has fixed block 13 with its opening confined, is provided with drive locking axle 11 in the hollow lag 1 towards the spring 12 of elevator well inner wall removal mutually, the one end of spring 12 with pin the one end butt that the axle kept away from elevator well inner wall, its other end and fixed block 13 are close to the terminal surface butt of locking axle 11. Utilize spring 12 to exert towards the elasticity that elevator shaft way inner wall removed to locking axle 11, locking axle 11 can keep with the butt of elevator well inner wall when the cage removes, locking axle 11 can insert in the reservation mouth of elevator well inner wall automatically under the effect of the elasticity that spring 12 applyed when the cage removes, makes the displacement of cage can receive the restriction, can directly not drop to elevator well bottom, has reduced the emergence of constructor injured's the condition.

As shown in fig. 2, since the side wall of the lock shaft 11 has a small grippable area when the lock shaft 11 is pulled out of the prepared opening, the process of moving the lock shaft 11 is difficult. Therefore, the end of the locking shaft 11 close to the spring 12 is welded with the wire rope 14, the end surface of the fixed block 13 coaxially penetrates through the communication hole 131, and the wire rope 14 can penetrate through the communication hole 131. When the locking shaft 11 is moved, the locking shaft 11 is driven to move through the steel wire rope 14, and a point capable of directly applying force exists during the movement, so that the locking shaft 11 is more convenient to move.

As shown in fig. 2, since the movement of the wire rope 14 still needs to be manually restricted after the locking shaft 11 is pulled out from the prepared opening by the wire rope 14, the locking shaft 11 is not directly inserted into the prepared opening. Therefore hollow lag 1 outer joint has stopper 25, and the one end welding that locking axle 11 was kept away from to wire rope 14 has couple 15, when locking axle 11 extracts in the reservation mouth of elevator well inner wall, couple 15 can collude with stopper 25 and hold. The movement of the locking shaft 11 is limited by the matching of the hook 15 and the limiting block 25, so that the movement of the locking shaft 11 is not limited manually, and the use of the safety device is more convenient.

As shown in fig. 2, after the position of the hook 15 is limited by the limit block 25, the worker forgets to disconnect the hook 15 from the limit block 25 when moving the cage, and the safety device cannot play a role in preventing the cage from falling when the cage falls. Therefore, the hollow protecting sleeve 1 is connected with a driving mechanism 2 which enables the hook 15 and the limiting block 25 to be automatically separated, and the driving mechanism 2 comprises a driving wheel 21 which is rotatably connected with the hollow protecting sleeve 1, a driving rod 22 which is connected with the end face of the driving wheel 21, a connecting rod 23 which is rotatably connected with the outer wall of the hollow protecting sleeve 1 and a torsion spring 24 which enables the connecting rod 23 to keep horizontal. The lateral wall of the driving wheel 21 can be abutted against the inner wall of the elevator shaft and is positioned at one end of the hollow protection sleeve 1 far away from the fixed block 13. The driving rod 22 is arranged on the end face of the driving wheel 21 far away from the hollow protection sleeve 1, and the axis of the driving rod is not coincident with the axis of the driving wheel 21. The connecting rod 23 is arranged between the fixing block 13 and the driving wheel 21, the limiting block 25 is welded at one end of the connecting rod 23 far away from the driving wheel 21, and the upper end face and the lower end face of the connecting rod 23 protrude out of the upper end face and the lower end face of the connecting rod 23. The length of the connecting rod 23 is smaller than the distance of the axis of the driving wheel 21 arranged in one end of the connecting rod away from the driving wheel 21, and the side wall of the driving rod 22 can be abutted with the upper end face or the lower end face of the connecting rod 23. When cage rebound, collude couple 15 and hold in stopper 25 upper end, later drive wheel 21 when cage rises again and rotate, actuating lever 22 is kept away from stopper 25's one end to connecting rod 23 and is applyed ascending power, thereby make the drive block rebound make couple 15 and stopper 25 break away from the connection, collude couple 15 and stopper 25 lower extreme and hold when cage descends, actuating lever 22 can drive connecting rod 23 and keep away from the one end rebound of stopper 25 this moment, make couple 15 and stopper 25 break away from the connection, no longer need the manual work to make couple 15 and stopper 25 break away from the connection this moment, locking axle 11 can be automatic and well inner wall butt after cage removal one section distance, thereby make the guard action that plays that safety device can be stable.

As shown in fig. 2, since the position of the driving rod 22 cannot be controlled during the movement of the cage, when the hook 15 is hooked on the limiting block 25, the driving rod 22 directly moves the connecting rod 23 to rotate, so that the locking shaft 11 is directly inserted into the reserved opening. Therefore, a plurality of mounting holes 211 are formed in the circumferential direction of the end face of the driving wheel 21 far away from the hollow protective sleeve 1, and one end of the driving rod 22 can be inserted into the mounting holes 211. After the hook 15 is connected to the stopper 25, the driving rod 22 is inserted into the mounting hole 211 closest to the connecting rod 23, into the mounting hole 211 located above the connecting rod 23 when the cage is raised, and into the mounting hole 211 located below the connecting rod 23 when the cage is lowered, and at this time, the position of the driving rod 22 can be adjusted so that the hook 15 does not directly disengage from the stopper 25 when the driving wheel 21 rotates.

As shown in fig. 2, the driving wheel 21 is continuously rotated when the cage moves, which causes the driving rod 22 to be disengaged from the mounting hole 211. Therefore, the friction ring 212 is coaxially adhered to the mounting cavity, the friction ring 212 is made of rubber, and the inner wall of the friction ring can abut against the outer wall of the driving rod 22. The friction ring 212 increases the friction between the driving rod 22 and the driving wheel 21, so that the driving rod 22 is not easily disconnected from the driving wheel 21, and the driving mechanism 2 is stably used.

As shown in fig. 2, the inner wall of friction ring 212 has a diameter slightly smaller than the diameter of drive rod 22, since friction ring 212 increases the friction force with drive rod 22 by applying a force to drive rod 22 toward the axis of drive rod 22. Therefore, the wedge-shaped surface 213 is disposed at the opening of the inner wall of the friction ring 212 away from the driving wheel 21, and the area of the opening of the friction ring 212 away from the driving wheel 21 is increased by the wedge-shaped surface 213, so that the driving rod 22 can be easily inserted into the inner cavity of the friction ring 212.

As shown in fig. 2, the driving rod 22 and the connecting rod 23 are easily deformed because the driving rod 22 continuously collides with the connecting rod 23 during the movement of the cage. Therefore, the driving rod 22 is coaxially sleeved with the buffer sleeve 221, the buffer sleeve 221 is made of rubber, and the outer wall of the buffer sleeve can be abutted against the connecting rod 23. The buffer sleeve 221 reduces the impact force between the drive rod 22 and the connecting rod 23, so that the connecting rod 23 and the drive rod 22 are not easily deformed when in contact.

The working principle is as follows:

when the cage moves, the steel wire rope 14 is pulled to pull the locking shaft 11 out of the reserved opening, the hook 15 at the other end of the steel wire rope 14 is hooked with the limiting block, the hook 15 is hooked at the upper end or the lower end of the limiting block 25 according to the ascending or descending of the cage, then the driving rod 22 is inserted into the mounting hole 211 which is closest to the connecting rod 23, and the driving rod 22 is positioned at the upper end or the lower end of the connecting rod 23 according to the ascending or descending of the cage. Thereby later the cage removes and drives drive wheel 21 and rotate, keeps off after the cage removes the one end distance, actuating lever 22 drives connecting rod 23 and keeps away from the one end rotation of stopper 25, makes couple 15 and stopper 25 break away from the connection, the locking pole at this moment under the effect of the elasticity that spring 12 applyed with elevator well inner wall butt, later the cage continues to remove, insert in the reservation mouth when locking axle 11 aligns with the reservation mouth.
