[0028] As recorded in the background art, traditional freight elevator machine rooms often adopt a relatively loose layout design to ensure the safe operation and convenient maintenance of equipment. However, this design method inevitably occupies a large building space, increases the construction cost, and also limits other usage functions of the building. Especially in some buildings with limited space, such as the renovation of old buildings, small commercial complexes, etc., the layout method of traditional freight elevator machine rooms often fails to meet the actual needs.
[0029] To solve this technical problem, the present utility model provides a compact elevator traction device.
[0030] Specifically, please refer to Figures 1 - 3 , the compact elevator traction device specifically includes:
[0031] A traction machine frame, a fixed pulley mounting channel steel 6, and a fixed pulley mounting backing plate 5;
[0032] Among them, the traction machine frame is composed of an upper layer frame 3 and a lower layer frame, and is arranged in a two-layer structure. A traction machine main body 4 is installed on the upper layer frame 3. A fixed pulley main body 7 is arranged between the fixed pulley mounting channel steel 6, the fixed pulley mounting backing plate 5, and the lower layer frame;
[0033] It further includes a rope socket mounting plate 8 and a rope socket assembly 9 arranged on the rope socket mounting plate 8. The rope socket mounting plate 8 is installed between the fixed pulley mounting channel steel 6 and the lower layer frame.
[0034] For the compact elevator traction device provided by the present utility model, in this application, through the two-layer arrangement of the traction machine frame, the traction machine main body 4 is installed on the upper layer frame 3, one side of the fixed pulley main body 7 is installed on the fixed pulley mounting channel steel 6, and the other side is installed on the lower layer frame through the fixed pulley mounting backing plate 5. The rope socket assembly 9 and the rope socket mounting plate 8 are installed on the fixed pulley mounting channel steel 6 and the lower layer frame. Through the height difference of the upper layer frame, the traction machine main body 4 is staggered from the fixed pulley main body 7 and the rope socket assembly 9 in height, ensuring the installation and operation space.
[0035] In order to enable those skilled in the art to better understand the solution of the present utility model, the technical solutions in the embodiments of the present utility model will be clearly and completely described below in conjunction with the accompanying drawings.
[0036] It should be noted that, without conflict, the embodiments in the present utility model and the features and technical solutions in the embodiments can be combined with each other.
[0037] It should be noted that similar reference numerals and letters indicate similar items in the following drawings. Therefore, once an item is defined in one drawing, it does not need to be further defined and explained in subsequent drawings.
[0038] Embodiment 1, please refer to Figures 1 - 3 , a compact elevator traction device, including a traction machine frame, a fixed pulley mounting channel steel 6, and a fixed pulley mounting backing plate 5;
[0039] Among them, the traction machine frame is composed of an upper layer frame 3 and a lower layer frame, and is arranged in a two-layer structure. A traction machine main body 4 is installed on the upper layer frame 3. A fixed pulley main body 7 is arranged between the fixed pulley mounting channel steel 6, the fixed pulley mounting backing plate 5, and the lower layer frame;
[0040] It further includes a rope socket mounting plate 8 and a rope socket assembly 9 provided on the rope socket mounting plate 8. The rope socket mounting plate 8 is mounted between the fixed pulley mounting channel steel 6 and the lower layer frame.
[0041] In this application, through the setting of two layers of the traction machine frame, the traction machine main body 4 is installed on the upper layer frame 3, one side of the fixed pulley main body 7 is installed on the fixed pulley mounting channel steel 6, and the other side is installed on the lower layer frame through the fixed pulley mounting cushion plate 5. The rope socket assembly 9 and the rope socket mounting plate 8 are installed on the fixed pulley mounting channel steel 6 and the lower layer frame. Through the height difference of the upper layer frame, the traction machine main body 4 is staggered from the fixed pulley main body 7 and the rope socket assembly 9 in height, ensuring the installation and operation space.
[0042] Furthermore, as Figures 1 - 3 shown, the lower layer frame includes a first lower layer frame 1 and a second lower layer frame 2 installed at the bottom of the upper layer frame 3. The first lower layer frame 1 is located between the second lower layer frame 2 and the fixed pulley mounting channel steel 6.
[0043] The first lower layer frame 1 and the second lower layer frame 2 are originally used to support the upper layer frame 3, but the first lower layer frame 1 also cooperates with the fixed pulley mounting channel steel 6 and the fixed pulley mounting cushion plate 5 to support the fixed pulley main body 7, and the first lower layer frame 1 also cooperates with the fixed pulley mounting channel steel 6 and the rope socket mounting plate 8 to support the rope socket assembly 9, making the occupied space small, the space utilization rate high, and the adaptability wide. This structure has great advantages in the dimensions occupied in width, depth, and height, and can adapt to more situations of extreme machine room sizes; it reduces material consumption and improves production efficiency. Through the mutual borrowing between components, the number of components is reduced, the utilization efficiency of components is improved, the usage amount of steel is reduced, the workload of workshop workers is reduced, and the production efficiency is improved; it is convenient for installation because the number of components of this structure is less than that of the same type of elevator, and the integration of components is high, reducing the workload of installation workers and improving work efficiency; in summary, this application has advantages such as wide adaptability, low cost, and convenient installation, making the product have high market competitiveness.
[0044] Refer to Figure 2 , Figure 2 The dotted line marked at A in is the path of the traction steel wire rope.
[0045] In Embodiment 2, the compact elevator traction device provided in Embodiment 1 is further optimized. Specifically, as Figure 2 shown, the fixed pulley mounting cushion plate 5 is installed on the top of the first lower layer frame 1, enabling the first lower layer frame 1 to support the fixed pulley mounting cushion plate 5.
[0046] Furthermore, as Figures 1 - 3As shown, a first connecting member is provided between the fixed pulley main body 7, the fixed pulley mounting backing plate 5 and the fixed pulley mounting channel steel 6. The first connecting member can support the fixed pulley main body 7 through the fixed pulley mounting backing plate 5 and the fixed pulley mounting channel steel 6.
[0047] Further, as Figures 1 - 3 shown, the first connecting member includes two first U-shaped clamps 702 respectively mounted on the fixed pulley mounting backing plate 5 and the fixed pulley mounting channel steel 6 by nuts. A first support shaft 701 is inserted and connected between the two first U-shaped clamps 702. The fixed pulley main body 7 is sleeved on the outer surface of the first support shaft 701 through a bearing, and the first U-shaped clamp 702 can fix the first support shaft 701.
[0048] Further, as Figure 2 shown, horizontal planes are provided at the bottoms of both ends of the first support shaft 701, and the horizontal planes are in contact with the fixed pulley mounting backing plate 5 and the fixed pulley mounting channel steel 6. The setting of the horizontal planes can cooperate with the fixed pulley mounting backing plate 5 and the fixed pulley mounting channel steel 6 to limit the first support shaft 701 and reduce the rotation and horizontal movement of the first support shaft 701.
[0049] Embodiment 3 further optimizes the compact elevator traction device provided in Embodiment 1 or 2. Specifically, as Figures 1 - 2 shown, two machine rest beams 10 are provided between the bottoms of the first lower frame 1, the second lower frame 2 and the fixed pulley mounting channel steel 6, and both machine rest beams are perpendicular to the first lower frame 1, the second lower frame 2 and the fixed pulley mounting channel steel 6.
[0050] Further, as Figures 1 - 2 shown, guide wheel brackets 11 are provided at the bottoms of both machine rest beams 10, a guide wheel main body 12 is provided between the two guide wheel brackets 11, and a second connecting member is provided between the guide wheel main body 12 and the two guide wheel brackets 11;
[0051] In this application, by stacking the heights of the double-layer frame, the machine rest beam 10 and the guide wheel bracket 11, the movement spaces of the traction steel wire rope and the fixed pulley main body 7 are staggered, improving the space utilization rate. And because the height distance between the traction wheel and the guide wheel main body 12 is relatively large, the wrap angle of the traction steel wire rope on the traction wheel is increased, increasing the traction force.
[0052] Further, as Figures 1 - 2 shown, the second connecting member includes two second U-shaped clamps 122 respectively provided on the two guide wheel brackets 11 by nuts. A second support shaft 121 is inserted and connected between the two second U-shaped clamps 122. The guide wheel main body 12 is sleeved on the outer surface of the second support shaft 121 through a bearing, and the second U-shaped clamp 122 can fix the second support shaft 121.
[0053] Further, as Figures 1 - 2 shown, horizontal planes are also provided at the tops of both ends of the second support shaft 121, and the horizontal planes are in contact with the bottoms of the guide wheel brackets 11. The arrangement of the horizontal planes can cooperate with the two guide wheel brackets 11 to limit the second support shaft 121, reducing the rotation and horizontal movement of the second support shaft 121.
