Description

Technical Field

[0001] The utility model relates to the technical field of a traction machine winch for elevator emergency rescue, in particular to a large-load winch structure. Background Art

[0002] As market supervision requirements become increasingly stringent, car elevators have been eliminated; at this time, large-load elevators of 10 tons and 20 tons have officially entered the market. However, when the elevator stops due to a fault and the car is far away from the elevator leveling position, the trapped person cannot leave the car smoothly, and the passengers can be released after manual leveling. Use elevator winching for emergency rescue, put the winch wheel axle on the main engine winch axle hole, then press the brake release handle, release the brake device, and slowly turn the winch wheel to make the car go up or down. At present, when winching with a large load, due to the large rated load, when releasing the brake and winching, the main engine wheel torque is very large. When it is transmitted to the winch wheel axle, the manpower cannot press it back, causing the winch wheel to tilt, the contact surface of the two gears to be reduced, and the main engine gear is damaged during winching, and manual winching rescue fails. Utility Model Content

[0003] The utility model aims to overcome the technical problem that when the brake is released and the turning gear is turned, the main engine gear will give a huge radial force, which causes the turning gear shaft to tilt, and provide a large-load turning gear structure.

[0004] The technical solution of the utility model is as follows:

[0005] A large-load turning gear structure comprises a machine base, a traction machine, a traction wheel, a main machine gear, a fixed turning wheel, a turning gear shaft, a turning gear and a group of auxiliary gears, wherein the machine base is equipped with the traction machine, the traction wheel is coaxially fixed to the outside of the rotor of the traction machine, an integrally formed main machine gear is provided on the circumference of the outer circle of the rotor of the traction machine, the fixed turning wheel is rotatably inserted into the machine base through the turning gear shaft, the turning gear shaft is equipped with the turning gear, the main machine gear is meshed with one side of the turning gear, the group of auxiliary gears are rotatably inserted into the machine base through the rotating shaft, and the group of auxiliary gears are meshed with the other side of the turning gear.

[0006] Furthermore, brake release wrenches connected to the traction machine are installed on both sides of the machine base.

[0007] Furthermore, the machine base is provided with supporting force holes for inserting the disc axle and the rotating shaft.

[0008] Compared with the prior art, the beneficial effect of the utility model is that the utility model provides a large-load turning gear structure, which can be used to offset the radial force of the main gear during turning by adding a group of auxiliary gears on the other side of the turning gear, thereby ensuring the normal meshing of the main gear and the turning gear, achieving the turning close to the level floor, and allowing passengers to leave the car safely.

[0013] In order to make the purpose, technical solution and advantages of the utility model more clear, the utility model is further described in detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described here are only used to explain the utility model and are not used to limit the utility model.

[0014] In order to illustrate the technical solution of the present invention, specific embodiments are provided below for illustration.

[0015] Example

[0016] See also Figures 1 to 3 The present embodiment provides a large-load turning structure, including a machine base 1, a traction machine, a brake release wrench 2, a traction wheel 3, a main machine gear 4, a fixed turning wheel 5, a turning shaft 6, a turning gear 7 and a group of auxiliary gears 8. The traction machine is installed in the machine base 1, and brake release wrenches 2 connected to the traction machine are installed on both sides of the machine base 1. The turning is manually performed by the brake release wrench 2. The traction wheel 3 is coaxially fixed to the outer side of the rotor of the traction machine, and an integral main machine gear 4 is provided on the circumference of the outer circle of the rotor of the traction machine. The fixed turning wheel 5 is rotatably inserted into the machine base 1 through the turning shaft 6. The machine base 1 is provided with a supporting force hole for inserting the turning shaft 6. The turning shaft 6 is provided with a turning gear 7. The main machine gear 4 is meshed with one side of the turning gear 7. A group of auxiliary gears 8 are rotatably inserted into the machine base 1 through a rotating shaft 9. The machine base 1 is provided with a supporting force hole for inserting the rotating shaft 9. A group of auxiliary gears 8 are meshed with the other side of the turning gear 7.

[0017] Structural principle: The brake release wrench 2 is moved, and the traction wheel 3 and the main engine gear 4 are driven to rotate through the traction machine 3, thereby driving the turning gear 7 to rotate, so as to achieve the purpose of emergency rescue.

[0018] The purpose of adding a set of auxiliary gears 8 on the other side of the turning gear 7 of the large-load turning structure is to offset the radial force of the main gear 4 when turning the car, thereby ensuring the normal meshing of the main gear 4 and the turning gear 7, so as to achieve the leveling of the turning car and allow passengers to leave the car safely, thereby overcoming the technical problem that the main gear 4 will give a huge radial force when the brake is released and the turning car is turned, causing the turning shaft 6 to tilt.
