Description

Technical Field

[0001] This utility model belongs to the technical field of elevator traction machines, and particularly relates to an elevator traction machine with an adjustable installation position. Background Technology

[0002] A patent titled "An Elevator Traction Device" (application number CN202222820594.3) is disclosed in the existing Chinese patent database. This device includes a motor, a traction sheave, a brake, a support base, and an encoder. The motor is connected to the support base and includes a drive shaft with a first end and a second end that are relatively far apart. The first end of the drive shaft is connected to the traction sheave, and the second end is connected to the brake. The traction sheave is connected to the support base, which has space to accommodate the traction sheave. The side of the support base away from the motor is opposite to the guide rail and maintains a gap with the guide rail. The encoder is located on the side of the motor away from the support base. The elevator traction device provided by this invention has the traction sheave connected within the space of the support base. The traction sheave and the brake are respectively installed on both sides of the motor. The side of the support base away from the motor is opposite to the guide rail and maintains a gap with the guide rail. Both the brake and the encoder are located away from the traction sheave, avoiding interference with the guide rail. Furthermore, the brake and encoder are easy to maintain and install, resulting in low maintenance costs.

[0003] In the prior art, the position of the elevator traction machine is difficult to adjust during installation, resulting in low accuracy of the installation position. This makes it difficult for the steel wire rope to maintain a reasonable pretension during elevator operation. Therefore, this paper aims to propose an elevator traction machine with an adjustable installation position. The installation position of the traction machine can be adjusted by driving the reducer, so that the elevator steel wire rope can always maintain a reasonable pretension during operation. Utility Model Content

[0004] The technical problem to be solved by this utility model is how to adjust the longitudinal installation position of the traction machine. In order to solve the above technical problem, this utility model provides an elevator traction machine with an adjustable installation position.

[0005] To achieve the above objectives, this utility model is implemented through the following technical solution:

[0006] An elevator traction machine with adjustable installation position includes a traction machine body and a mounting frame, including a suspended guide frame. The mounting frame is slidably connected to the guide frame. The upper end of the mounting frame is provided with a mounting surface connected to the traction machine body. The cross-section of the guide frame is U-shaped. A flange is fixedly connected to one end of the guide frame. A reducer is fixedly installed on the outer surface of the flange. A hinge seat is fixedly installed at the other end of the guide frame. A lead screw is provided in the guide frame between the hinge seat and the flange. A lead screw nut seat is sleeved on the lead screw. A horizontal waist-shaped groove is opened on the side of the guide frame. A first pin is fixedly inserted into the side of the lead screw nut seat. The free end of the first pin passes through the waist-shaped groove and is inserted into the corresponding side of the mounting frame.

[0007] Compared with the prior art, the beneficial effects of this utility model are as follows: due to the cooperative arrangement between the mounting frame and the guide frame, the installation position of the traction machine body is adjustable, avoiding the phenomenon of the wire rope being too tight or too loose due to the position of the traction machine. This ensures that the wire rope can always maintain a reasonable pretension during operation. By adjusting the position of the traction machine, the actual tension length of the wire rope can be precisely controlled, so that its pretension completely matches the design value. This device is suitable for industrial production and has strong practicality.

[0008] As a preferred embodiment, a set of guide rails is integrally provided on both the upper and lower surfaces of the guide frame. The length direction of the guide rails is consistent with the length direction of the lead screw. Second pins are inserted into both sides of the mounting frame. Rollers are sleeved on the second pins located between the mounting frame and the guide frame. Each roller is rotatably connected to the corresponding guide rail.

[0009] As a preferred option, limit baffles are integrally welded onto the guide frames located at both free ends of the guide rail.

[0010] As a preferred embodiment, the mounting bracket includes a sliding connection portion that is slidably sleeved outside the guide frame, and the cross-section of the sliding connection portion is arranged in a "U" shape.

[0011] As a preferred embodiment, an mounting block is integrally welded onto the inner wall of the guide frame on the inner side of the hinge seat, and the four corners of the hinge seat are fixedly connected to the mounting block by bolts.

[0012] As a preferred embodiment, the guide frame includes fixed pads, with both ends of the guide frame placed on the corresponding pads and welded in place. Attached Figure Description

Detailed Implementation

[0018] The technical solution of this application will be further described below with reference to the accompanying drawings and embodiments.

[0019] like Figure 1-3 As shown, an elevator traction machine with adjustable installation position includes a traction machine body 1 and a mounting frame 2. It includes a suspended guide frame 3, on which the mounting frame 2 is slidably connected. The upper end of the mounting frame 2 has a mounting surface 201 connected to the traction machine body 1. The guide frame 3 has a U-shaped cross-section. One end of the guide frame 3 is fixedly connected to a flange 4, and a reducer 5 is fixedly installed on the outer surface of the flange 4. The other end of the guide frame 3 is fixedly installed with a hinge seat 6. A lead screw 7 is installed inside the guide frame 3 between the hinge seat 6 and the flange 4. Both ends of the lead screw 7 are connected to the hinge seat 6 and the flange 4 respectively via bearings. A lead screw nut seat 8 is sleeved on the lead screw 7. A horizontal waist-shaped groove 9 is opened on the side of the guide frame 3. A first pin 10 is fixedly inserted into the side of the lead screw nut seat 8. The free end of the first pin 10 passes through the waist-shaped groove 9 and is inserted into the corresponding side of the mounting frame 2. A set of guide rails 11 is integrally formed on both the upper and lower surfaces of the guide frame 3. The length direction of the guide rails 11 is consistent with the length direction of the lead screw 7. Second pins 12 are inserted into both sides of the mounting frame 2. Rollers 13 are sleeved on the second pins 12 located between the mounting frame 2 and the guide frame 3. Each roller 13 is rotatably connected to the corresponding guide rail 11. Limiting baffles 14 are integrally welded to the guide frame 3 at both free ends of the guide rails 11. The limiting baffles 14 prevent the mounting frame 2 from sliding out of the guide rails 11, thus improving the safety of the device. The mounting frame 2 includes a sliding connection part 202 that is slidably sleeved on the outside of the guide frame 3. The cross-section of the sliding connection part 202 is U-shaped. Mounting blocks 15 are integrally welded to the inner wall of the guide frame 3 inside the hinge seat 6. The four corners of the hinge seat 6 are fixedly connected to the mounting blocks 15 by bolts. It includes a fixed pad 16, and the two ends of the guide frame 3 are placed on the corresponding pad 16 and welded and fixed.

[0020] In operation, the operator controls the reducer 5. When the reducer 5 drives the lead screw 7 to rotate, causing the lead screw nut seat 8 to move to the left, the mounting bracket 2 moves synchronously to the left along with the lead screw nut seat 8. Figure 4 As shown, the traction sheave on the traction machine body 1 will compress the wire rope, causing it to become overly tight. Prolonged overtightness will keep the wire rope under high stress, accelerating fatigue. When the reducer 5 drives the lead screw 7 to rotate, causing the lead screw nut seat 8 to move to the right, the mounting bracket 2 moves synchronously to the right along with the lead screw nut seat 8. Figure 4 As shown, the traction sheave on the traction machine body 1 will move away from the wire rope, causing the wire rope to become slack. The slack wire rope is prone to slipping on the groove of the traction sheave body when the elevator starts / brakes, reducing the traction efficiency.
