Description

Technical Field

[0001] The utility model belongs to the technical field of traction machine structures, and in particular relates to a front-mounted traction machine encoder structure. Technical Background

[0002] An elevator traction machine is the elevator's power source, also known as the main unit. Its function is to transmit and transfer power to keep the elevator running. The traction machine consists of a base, stator windings, rotor assembly, brake, and encoder.

[0003] Traction machines can be divided into two types according to the installation method of the encoder: front-mounted and rear-mounted. Front-mounted means that the encoder is installed from the front of the traction machine, including but not limited to the maintenance and replacement of the encoder can be completed at the front of the traction machine; rear-mounted means that the encoder is installed from the rear of the traction machine, including but not limited to the maintenance and replacement of the encoder can be completed at the rear of the traction machine; currently, the installation methods of traction machines can be divided into two types: with a machine room and without a machine room. When installed without a machine room, the traction machine often encounters an installation method that requires the rear to be close to the wall. The remaining space behind the traction machine is very limited. If the rear-mounted encoder is still used, once the encoder fails or is damaged, maintenance and replacement will be very time-consuming and labor-intensive. At this time, the front-mounted encoder is particularly important. This patent provides a front-mounted traction machine encoder structure that can effectively solve this problem. Utility Model Content

[0004] The purpose of the utility model is to provide a front-mounted traction machine encoder structure to solve the problems in the prior art.

[0005] The utility model is realized through the following technical solution: a front-mounted traction machine encoder structure, the traction machine includes a machine base, a rotor, a traction wheel and a protective cover, and is characterized in that: the front-mounted traction machine encoder structure includes an encoder fixing frame and an encoder connecting block; the encoder fixing frame includes a frame body and an encoder seat matching the encoder, the frame body is connected to the machine base, and the frame body and the encoder seat are fixed together by bolts; the encoder connecting block is fixed in the center hole of the rotor and is fixedly connected to the rotating shaft of the encoder.

[0006] Furthermore, the encoder connecting block is installed in the center hole of the traction machine rotor in an interference fit manner, and a fixing hole matching the encoder rotating shaft is provided on the encoder connecting block.

[0007] Furthermore: the protective cover is arranged on the outside of the encoder fixing frame, and an opening for avoidance is provided on the protective cover.

[0008] Furthermore: the protective cover is provided with a wire outlet hole for the encoder.

[0009] The beneficial effect of this utility model is that by installing the encoder in front of the traction machine, it solves the problem of the encoder being installed behind the traction machine and close to the wall behind the traction machine, which makes it difficult to maintain and replace the encoder in the event of encoder failure or damage. This provides elevator maintenance personnel with a safer and more effective encoder maintenance and replacement solution, improving the safety and efficiency of elevator maintenance personnel during elevator maintenance operations.

[0017] The following is a further clear and complete description with reference to the accompanying drawings of the present invention.

[0018] like Figure 1-5 As shown, the utility model discloses a front-mounted traction machine encoder structure, the traction machine includes a machine base 1, a rotor 2, a traction wheel and a protective cover 6; the front-mounted traction machine encoder structure includes an encoder 3, an encoder fixing frame 5 and an encoder connecting block 7;

[0019] The encoder fixing frame 5 includes a frame body 51 and an encoder seat 52 that cooperates with the encoder. The frame body 51 is N-shaped, and its lower part is connected to the machine base by bolts. It always remains stationary in the working state. The encoder seat 52 is cylindrical, with a bottom at the rear end (close to the traction machine side) and an opening on the bottom plate for the rotating shaft to extend. The front end of the encoder seat is open and has a flange at the front end. The flange is fixed to the frame body 51 by bolts. The frame body 51 is also provided with an opening that cooperates with the encoder seat, so that the encoder 3 can be installed or removed from the opening.

[0020] The encoder connecting block is fixed in the central hole of the rotor, is coaxially matched with the rotor, and is fixedly connected to the rotating shaft of the encoder.

[0021] Preferably, the encoder connection block 3 is installed in the center hole of the traction machine rotor in an interference fit manner, and a fixing hole is provided on the encoder connection block to match the encoder rotating shaft. The encoder rotating shaft is inserted into the fixing hole and fixed by bolts.

[0022] Preferably, the protective cover is arranged on the outside of the encoder fixing frame 5, and an opening for avoidance is provided on the protective cover, which cooperates with the two sides of the N-shaped frame and fits as closely as possible without interfering with each other to ensure protection of the traction wheel.

[0023] Preferably, the protective cover is provided with an encoder wire outlet hole, and the encoder cable 4 is led out from the wire outlet hole.

[0024] The encoder of the present invention can be installed and disassembled directly from the front. During installation, the encoder is directly placed into the encoder seat through the opening on the frame, and the encoder shaft is inserted into the hole of the encoder connecting block. After installation, a bolt is passed through the inner hole of the encoder shaft and connected to the thread in the hole of the encoder connecting block to fix the shaft to the encoder connecting block. At the same time, the main body of the encoder is fixed to the frame with the bolt. The installation is completed, and the disassembly process can be reversed.

[0025] This new structure, by installing the encoder in front of the hoist, solves the problem of having the encoder behind the hoist and installed close to the wall behind the hoist, making encoder maintenance and replacement difficult in the event of encoder failure or damage. This provides elevator maintenance personnel with a safer and more effective encoder maintenance and replacement solution, improving the safety and efficiency of elevator maintenance operations.
