Embodiment 1

[0046] Embodiment 1: An elevator equipped with a safety circuit detection system and a manual rescue device (see figure 1 figure 2 image 3 Figure 4 ), including: including traction machine 17, traction wheel 5, worm gear mechanism 20, synchronous mechanism and manual rescue device.

[0047] The traction machine is arranged on the installation platform 3 at the top of the elevator shaft. The traction machine in this embodiment adopts a servo motor, and the servo motor can accurately control the speed. Connection to mains via main safety contactor contacts. One end output of the traction machine is coaxially connected with the traction wheel through a coupling 18 . The other side of the traction sheave is connected with the worm gear mechanism through a coupling. A traction rope is wound around the traction sheave, one end of the traction rope is connected to the car after passing around the diverting pulley, and the other end of the traction rope is connected to the cou...

Embodiment 2

[0053] Embodiment 2: An elevator equipped with a safety loop detection system and a manual rescue device. The difference from Embodiment 1 is that a linkage rod 29 is used between the two worms to achieve linkage (see Figure 5 ), the worm gears of the two worm gears are on the same plane, the two worms are coaxially arranged, and the two worms are connected by a linkage rod. Manual driving device comprises driving rope and the driving wheel 28 that links to each other with worm screw, and driving rope cooperates with driving wheel, and driving rope stretches in the car. When rescue is needed, the passenger in the car pulls the driving rope, the driving rope drives the driving wheel to rotate, the driving wheel drives the two worms to rotate synchronously, and finally drives the two drums to rotate synchronously and release the traction rope. Refer to Example 1 for all the other structures.

[0054] In all the above embodiments, the traction machine is connected to the power ...

Embodiment 4

[0062] In this embodiment, several sub-control systems are also configured, each sub-control system is correspondingly connected with several switch detection modules, the input end of each sub-control system is directly connected with the switch detection module, and the output end of the sub-control system is connected The host control system is connected, and the remaining parts are the same as the above-mentioned embodiment.

Abstract

The invention relates to an elevator provided with a safety loop detecting system and a manual rescuing device. The elevator overcomes the defects in the prior art. According to the key points of thetechnology, the elevator comprises the manual rescuing device. The end portion of a traction rope is wound around the manual rescuing device. When rescuing is needed, the wound traction rope can be released to achieve the elevator level. The safety loop detecting system comprises a safety loop and a plurality of switch detecting modules, wherein the safety loop comprises main switches, a pluralityof limiting switches and a plurality of safety switches, a power source is connected with a main safety contact coil through the safety loop, and each switch detecting module corresponds to one mainswitch, one limiting switch or one safety switch. The output ends of the switch detecting modules are in communicating connection with a host control system through a safety bus. The first detecting ends of the switch detecting modules are connected with movable contacts of the main switches, the limiting switches or the safety switches. The second detecting ends of the switch detecting modules are connected with static contacts of the main switches, the limiting switches or the safety switches.

Description

technical field [0001] The invention relates to a traction device, in particular to an elevator equipped with a safety circuit detection system and a manual rescue device. Background technique [0002] In high-rise buildings, in order to adapt to the needs of height changes, lifting devices are a necessary supporting equipment, such as elevators, which can bring great convenience to users. [0003] An elevator is a vertical elevator powered by a motor, also known as a vertical elevator. The vertical elevator is equipped with a box-shaped gondola, which is used for multi-storey buildings to take people or carry goods. From the earliest first-step safety elevator to the modern automatic control elevator, although it has been developed for hundreds of years, most of the elevators are driven by a traction drive mechanism, including a traction machine set on the top of the hoistway. The traction machine is connected to the traction wheel, and there is a traction rope on the tra...
