[0024] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0025] Example 1

[0026] Please see Figures 1-4 As shown, an elevator dual-wheel traction machine includes a mounting plate 1;

[0027] The traction machine body 2 is fixedly mounted on the top of the mounting plate 1. An installation groove 3 is formed at the center of the traction machine body 2. A main shaft 5 is positioned between the centers of the left and right sides of the installation groove 3. Traction wheels 6 are positioned on both sides of the outer surface of the main shaft 5. An adjustment assembly 7 is provided between the traction wheels 6 and the main shaft 5. A limit assembly 8 is provided on the top of the traction machine body 2. During operation, the traction machine body 2 is first installed on the elevator using the mounting plate 1. After the installation is secure, the distance between the two traction wheels 6 is adjusted using the adjustment assembly 7 to accommodate the elevator. Then, the traction wheels 6 should also be adjusted... The operation of the limit component 8 limits the steel wire rope wound in the groove on the outer surface of the traction sheave 6. After the limit component 8 is activated, the steel wire rope can be pulled inside the elevator through the traction machine body 2. Therefore, the distance between the two traction sheaves 6 inside the traction machine body 2 can be adjusted by adjusting the component 7, making the traction machine adaptable to different elevators. This makes the traction machine convenient to use and highly practical. At the same time, the limit component 8 can cooperate with the adjustment of the traction sheave 6 and limit the steel wire rope wound on the outer surface of the traction sheave 6, thus making the traction machine perform well.

[0028] The mounting plate 1 has a through groove 4 that runs vertically through the center, and the inside of the through groove 4 corresponds to the traction sheave 6. During operation, the steel wire rope wound around the groove of the traction sheave 6 passes through the mounting plate 1 through the through groove 4.

[0029] The traction machine body 2 has limit grooves 804 on both its front and rear surfaces. A through-type guide groove 803 is formed at the center of the upper surface inside the limit groove 804. Limit plates 801 are slidably connected to the left and right sides inside the limit groove 804. A through-type threaded hole 805 is formed inside the limit plate 801, and a limit bolt 802 is threadedly connected inside the threaded hole 805. The top of the limit bolt 802 passes through the guide groove 803. During operation, the limit plate... 801 is placed on the outer surface of the traction sheave 6 to limit the wire rope. When the position of the traction sheave 6 is adjusted, the limiting bolt 802 is rotated to disengage it from the limiting plate 801. Then the limiting plate 801 is moved so that the limiting bolt 802 and the limiting plate 801 slide inside the limiting groove 804 inside the guide groove 803. After sliding to the position corresponding to the traction sheave 6, it stops. Then the limiting bolt 802 is rotated again to limit the position of the limiting plate 801, so that the limiting plate 801 remains in a stable position.

[0030] The two limiting plates 801 on the left and the two limiting plates 801 on the right are located in front of and behind the two traction wheels 6, respectively; during operation, the limiting plates 801 can limit the steel wire rope wound on the outer surface of the traction wheel 6.

[0031] The adjusting assembly 7 includes multiple evenly distributed grooves 701 formed on the outer surface of the main shaft 5. Multiple evenly distributed insertion holes 703 are formed on the side of each groove 701 near the center of the main shaft 5. A slider 702 is slidably connected inside the groove 701, and the side of the slider 702 away from the center of the main shaft 5 is fixedly connected to the inner wall of the traction wheel 6. A through hole 705 is formed at the center of the slider 702. Multiple evenly distributed inner grooves 710 are formed inside the traction wheel 6. A through groove 706 is formed on the side of each inner groove 710 near the center of the traction wheel 6. A rod 704 is slidably connected inside the through groove 706. One end of the rod 704, near the center of the traction sheave 6, passes through the through hole 705 and is inserted into the insertion hole 703. A spring 707 is sleeved on the outer surface of the rod 704 inside the through groove 706. One end of the spring 707, near the center of the traction sheave 6, is fixedly connected to the inner wall of the through groove 706. The other end of the spring 707, away from the center of the traction sheave 6, is fixedly connected to the outer surface of the rod 704. A plug block 708 is fixedly connected to the end of the rod 704 away from the center of the traction sheave 6. A limiting hole 711 is formed on the side of the inner groove 710 away from the center of the mounting groove 3. A pressing rod 709 is slidably connected inside the limiting hole 711, and the outer surface of the pressing rod 709 is located inside the inner groove 710 and fits against the outer surface of the insert block 708. A slot 712 is formed on the outer surface of the pressing rod 709. A through hole 713 is formed on the side of the inner groove 710 near the center of the mounting groove 3. A pull rod 714 is slidably connected inside the through hole 713, and one end of the pull rod 714 away from the center of the mounting groove 3 is fixedly connected to the end of the pressing rod 709. A second spring 715 is fitted inside the through hole 713 on the outer surface of the pull rod 714. One end of the second spring 715 away from the center of the mounting groove 3 is fixedly connected to the outer surface of the pull rod 714, and the other end of the second spring 715 near the center of the mounting groove 3 is fixedly connected to the inner wall of the through hole 713. A continuous groove 717 is formed on the side of the traction wheel 6 near the center of the mounting groove 3. A handle ring 718 is inserted into the groove 717, and the side of the handle ring 718 away from the center of the mounting groove 3 is fixedly connected to the end of the pull rod 714 near the center of the mounting groove 3.During operation, pulling the handle ring 718 causes the handle ring 718 to move the pull rod 714. After the pull rod 714 moves, it compresses the second spring 715, giving the second spring 715 a rebound force. Then, the movement of the pull rod 714 causes the compression rod 709 to move, making the slot 712 correspond to the insertion block 708. After the insertion block 708 corresponds to the slot 712, the rebound force of the previously compressed first spring 707 causes the insertion rod 704 and the insertion block 708 to move, so that the insertion block 708 is inserted into the slot 712. Immediately after the insertion block 708 and the insertion rod 704 move, the insertion rod 704 can be removed from the insertion hole 703 and disengaged. The slider 702 is limited, and the rebound force of the second spring 715, when compressed, is insufficient to compress the insert block 708 and the insert rod 704, and therefore will not compress the first spring 707. So, moving the handle ring 718 then moves the traction wheel 6 through the slider 702 sliding within the groove 701, limiting its movement. After adjusting to a suitable position, the insert rod 704 aligns with the other insertion hole 703. Then, squeezing the handle ring 718 causes the insert block 708 inside the slot 712 to move out, causing the insert rod 704 to insert into the insertion hole 703, limiting the position of the slider 702, thus ensuring the traction wheel 6 remains stable after adjustment.

[0032] The interior of the slot 712 and the outer surface of the insert 708 are both arc-shaped. The handle ring 718 has handle grooves 716 on the upper and lower sides of the side near the center of the mounting groove 3. During operation, the insert 708 is adapted to the slot 712, and it is convenient for the insert 708 to be inserted into and separated from the slot 712. The handle grooves 716 facilitate the movement of the handle ring 718.
