Detailed Description
The technical solutions in the embodiments of the present invention will be clearly and completely described below with reference to the drawings in the embodiments of the present invention, and it is obvious that the described embodiments are only a part of the embodiments of the present invention, and not all of the embodiments. All other embodiments, which can be derived by a person skilled in the art from the embodiments given herein without making any creative effort, shall fall within the protection scope of the present invention.
Referring to fig. 1-8, the present invention provides a technical solution: a speed reduction motor 3 is fixed on the shell of the gear box 1, a transfer mechanism 2 is arranged in the gear box 1, and the transfer mechanism 2 is arranged in the middle of the gear box 1. Meanwhile, chain wheels are arranged at the transfer mechanism 2 and the reducing motor 3, the chain wheels of the transfer mechanism 2 and the reducing motor 3 realize transmission through a chain 4, and a chain tensioning mechanism is arranged outside the gear box 1 and used for tensioning the chain 4;
the transfer mechanism 2 is provided with two middle rotating shafts 5, the two middle rotating shafts 5 are connected through a two-way backstop 6, and when the gear motor 3 is started, the gear motor drives the two-way backstop 6 to realize active rotation. When the bidirectional backstop 6 is actuated, the backstop is locked, and the safety protection effect is achieved. Two middle rotating shafts 5 are arranged on the gear box 1 through bearings and sealing rings, chain wheels are arranged on the middle rotating shafts 5 on one side, and the chain wheels are arranged outside the gear box 1.
Emergent pivot 9 of manual work is installed on gear box 1 through bearing and sealing washer, and emergent pivot 9 of manual work sets up in the one side that is close to gear motor 3, and emergent pivot 9 of manual work passes through gear engagement transmission with a well pivot 5. The shaft end of the artificial emergency rotating shaft 9 is provided with an inner hexagonal hole 10, and the rotation of the artificial emergency rotating shaft 9 can be realized through a hexagonal crank.
The output shaft 7 is arranged on the gear box 1 through a bearing and a sealing ring, the output shaft 7 is arranged on one side far away from the speed reducing motor 3, the speed reducing motor 3 is prevented from influencing the normal output of power, synchronous belt wheels 8 are arranged at two ends of the output shaft 7, and the output shaft 7 and the other middle rotating shaft 5 are in meshing transmission through gears; the synchronous belt wheel 8 is connected with devices such as a lifter or a weight box, and the like, so that the power output is realized.
When the chain 4 is disconnected or the speed reducing motor 3 stops working suddenly, the elevator connected with the synchronous belt wheel 8 suddenly drops, the output shaft 7 drives the middle rotating shaft 5 connected with the output shaft to rotate reversely suddenly, and the bidirectional backstop 6 works passively, so that locking is realized. Therefore, the two middle rotating shafts 5 cannot rotate reversely, and the locking of the synchronous belt wheel 8 is ensured. Devices such as the lift will hover in the original place, and operating personnel can rotate artifical emergent pivot 9 by hand this moment, realizes driving two mesoscopic shafts 5 and rotate with the same direction, and output shaft 7 normally rotates like this, and synchronous pulley 8 can drive devices such as lifts and accomplishes follow-up lift.
In order to ensure normal transmission between the speed reduction motor 3 and the transfer mechanism 2, the chain tensioning mechanism is provided with a mounting seat 11, the mounting seat 11 is provided with a sliding groove 12, a sliding block 13 is arranged in the sliding groove 12, a tensioning wheel 14 is arranged on the sliding block 13, and the chain tensioning mechanism is meshed with the chain 4 in the vertical displacement process of the tensioning wheel 14, so that the tensioning degree of the chain 4 is adjusted. The chain tensioning mechanism further comprises a rotating threaded rod 15, the gear box 1 is provided with a pair of mounting plates 16, and the mounting plates 16 are respectively arranged on the upper side and the lower side of the mounting seat 11. The mounting plate 16 is provided with an opening, and the rotary threaded rod 15 is rotatably arranged in the opening; the rotating threaded rod 15 is in threaded fit with the sliding block 13, so that in the process of rotating the rotating threaded rod 15, the sliding block 13 can drive the tension wheel 14 to realize vertical displacement due to the directional limiting effect of the sliding groove 12 on the sliding block 13, and the tension on the chain 4 is completed.

In order to avoid the problem that the tensioning sheave 14 cannot act on the chain 4.
The working principle is as follows: when the gear box 1 is installed on the lifting mechanism, power output is completed through the synchronous belt wheel 8, so that the lifting mechanism is driven to move up and down. However, when the chain 4 is disconnected or the reduction motor 3 suddenly stops working, the output shaft 7 drives the middle rotating shaft 5 connected with the output shaft to suddenly rotate in the reverse direction, and the bidirectional backstop 6 passively works, so that locking is realized. At this time, the lifting mechanism is suspended, and if the standby speed reducing motor 17 can be adopted, the chain 4 and the standby speed reducing motor 17 are installed.
When electrical problem or 4 fracture scheduling problems of chain appear, operating personnel need make artifical emergent pivot 9 rotate through the hexagonal crank, and the power that the manual work provided just is equivalent to the power that the motor gave like this to the realization provides the effect of power for elevating system.
In the process of adjusting the tensioning degree of the chain 4, an operator only needs to screw the rotating threaded rod 15, so that the tensioning wheel 14 is displaced up and down, and the tensioning of the chain 4 is realized.
