Specific implementation mode

[0025] Next, the technical solutions in the embodiments of the present utility model will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present utility model. Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all the embodiments. Based on the embodiments in the present utility model, all other embodiments obtained by those of ordinary skill in the art without making creative efforts belong to the scope of protection of the present utility model.

[0026] The present utility model provides a car top wheel assembly for an elevator as shown in Figures 1-5 which includes a fixed plate 1 and a fixed sleeve 5 installed on the upper side of the fixed plate 1;

[0027] A plurality of partitions 8 are arranged inside the fixed sleeve 5;

[0028] A rope 6 sleeved on the fixed sleeve 5 is arranged between the plurality of partitions 8;

[0029] A plurality of vertically through through holes 3 are opened inside the upper end outer wall of the fixed plate 1 to provide position limits for the up and down movement of the plurality of ropes 6. Under the combination of the fixed sleeve 5 and the partition 8, the winding position of the rope 6 is restricted. When the elevator car rises or falls, the rope 6 is guided by the fixed sleeve 5 to maintain a stable up and down movement track. When the rope 6 moves up and down, under the restriction of the through hole 3 in the fixed plate 1, it is ensured that the rope 6 can avoid large-amplitude shaking when moving up and down;

[0030] A separation box 10 is provided below the lower side of the through port 3. Inside the outer wall at the lower end of the separation box 10, a plurality of up-and-down open intercept ports 12 are provided to guide the moving positions of a plurality of ropes 6. Guide blocks 11 are fixedly connected to both the upper and lower sides of the plurality of intercept ports 12 to intercept the lubricating paste on the ropes 6. During the up-and-down movement of the ropes 6, the ropes 6 will be secondarily position-limited from the intercept ports 12 in the separation box 10. And during the up-and-down movement of the ropes 6, the upper guide blocks 11 can intercept the pre-coated lubricating paste on the ropes 6, reducing the adhesion of the lubricating paste on the surface of the ropes 6, thereby reducing the contaminated area of dust on the surface of the ropes 6, and guiding the intercepted lubricating paste into the interior of the separation box 10. And when the ropes 6 rise, the impurities attached to the surface of the ropes 6 during the rising process can be scraped off by the lower guide blocks 11, reducing the subsequent impurity adhesion of the ropes 6. And during the rising process of the ropes 6, they will secondarily contact the lubricating paste intercepted by the upper guide blocks 11 and reattach to the ropes 6, so that when the ropes 6 are wound on the fixed sleeve 5, they can still maintain a lubricated state, avoiding the occurrence of jamming during the winding process.

[0031] As Figure 4 and Figure 5 shown, an installation plate 15 is provided on the right side of the separation box 10 to fill the right opening of the separation box 10. A clamping block 13 that penetrates rightward into the interior of the installation plate 15 is fixedly connected to the outer wall at the right end of the separation box 10 to preliminarily limit the position of the installation plate 15. A fixing screw a14 that penetrates leftward into the interior of the separation box 10 is provided on the right side of the installation plate 15 to limit the position between the installation plate 15 and the separation box 10. A clamping groove for the clamping block 13 to be clamped is provided inside the installation plate 15, and threaded holes for the fixing screw a14 to be screwed are provided in both the clamping groove and the interior of the separation box 10.

[0032] During the use of the separation box 10, the opening on the right side of the separation box 10 can be filled by installing and fixing the installation plate 15. After the installation plate 15 is attached to the right opening position of the separation box 10, the clamping block 13 at the right end of the separation box 10 is inserted into the interior of the installation plate 15, and then the separation box 10 and the installation plate 15 are fixed by the fixing screw a14. The opening on the right side of the separation box 10 is convenient for subsequent maintenance personnel to clean the lubricating paste accumulated inside the separation box 10.

[0033] As Figure 4 and Figure 5 shown, a dust-proof cover 7 is provided on the upper side of the fixing plate 1 to sleeve the fixed sleeve 5 to block the falling dust. A plurality of connecting blocks 17 are fixedly connected to the lowermost sides of the outer walls at the left and right ends of the dust-proof cover 7. Fixing screws b16 that are screwed with the fixing plate 1 are provided on the upper outer walls of the plurality of connecting blocks 17 to limit the position of the dust-proof cover 7. The dust-proof cover 7 is transparent, and a plurality of guide blocks 11 are all inclined, and the upper and lower sides of the plurality of guide blocks 11 are symmetrical.

[0034] After the fixed sleeve 5 winds the rope 6 coated with the lubricating paste, the dust cover 7 can be sleeved on the fixed sleeve 5 to cover the fixed sleeve 5 and prevent dust from falling on the fixed sleeve 5. The connecting blocks 17 at the left and right ends of the dust cover 7 are attached to the fixed plate 1, and then the fixed plate 1 and the dust cover 7 are fixedly connected by fixing screws b16 to limit the position of the dust cover 7. The transparent dust cover 7 can intuitively show the state of the rope 6 inside the dust cover 7. The inclined guide block 11 is cylindrical and can be sleeved on the rope 6 to scrape off the lubricating paste and dust impurities on the rope 6.

[0035] As Figure 1 and Figure 2 shown, a fixing member a2 is fixedly connected to the outer wall of the upper end of the fixed plate 1 to pre-limit the installation position of the fixed sleeve 5. A fixing member b4 is fixedly connected to the outer wall of the upper end of the fixing member a2 to limit the position of the fixed sleeve 5. Positioning shafts 9 penetrating through the inside of the fixing member b4 are fixedly connected to the outer walls of the front and rear ends of the fixed sleeve 5 to limit the installation position of the fixed sleeve 5. The fixed plate 1, the fixing member a2, and the fixing member b4 are connected and fixed by fixing bolts.

[0036] When the fixed sleeve 5 is installed, through the mutual cooperation between the fixing member a2 and the fixing member b4, the fixed sleeve 5 is installed at an appropriate height and position. When the fixed sleeve 5 performs the winding and unwinding operations of the rope 6 driven by an external motor later, the positioning shaft 9 can drive the fixed sleeve 5 to perform the winding and unwinding operations.

[0037] The implementation principle of this embodiment is as follows: With the combination of the fixed sleeve 5 and the partition 8, the winding position of the rope 6 is restricted. When the elevator car rises or falls, the rope 6 moves up and down stably under the guidance of the fixed sleeve 5. When the rope 6 moves up and down, under the restriction of the through hole 3 in the fixed plate 1, the rope 6 can avoid large-amplitude shaking when moving up and down. During the up and down movement of the rope 6, the rope 6 will be secondarily position-restricted through the intercepting port 12 in the separation box 10. And during the up and down movement of the rope 6, the upper guide block 11 can intercept the lubricating paste pre-coated on the rope 6, reducing the adhesion of the lubricating paste on the surface of the rope 6, thereby reducing the contaminated area of dust on the surface of the rope 6, and guiding the intercepted lubricating paste into the separation box 10. And when the rope 6 rises, the impurities attached to the surface of the rope 6 during the rising process can be scraped off by the lower guide block 11, reducing the subsequent impurity adhesion of the rope 6. And during the rising process of the rope 6, the lubricating paste intercepted by the upper guide block 11 will come into secondary contact and reattach to the rope 6, so that the rope 6 can still maintain a lubricated state when wound on the fixed sleeve 5, avoiding jamming during the winding process.

[0038] Finally, it should be noted that the above are only the preferred embodiments of the present utility model and are not intended to limit the present utility model. Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments, or perform equivalent replacements for some of the technical features. Any modifications, equivalent replacements, improvements, etc. made within the spirit and principle of the present utility model shall be included within the protection scope of the present utility model.
