Description

Technical Field

[0001] This utility model relates to wheels, and more particularly to a roller and a high-speed material cart. Background Technology

[0002] A high-speed material transport vehicle is a vehicle used during elevator installation and maintenance to transport elevator components (such as guide rails, car walls, control cabinets, etc.) along tracks to different floors in the hoistway.

[0003] Rollers are an important component of high-speed material handling vehicles, used to roll along tracks. However, rollers are noisy and have poor wear resistance, which can lead to a short service life. At the same time, sand, iron filings and other impurities can easily remain on the tracks, resulting in poor rolling stability of the rollers. Utility Model Content

[0004] Purpose of the utility model: The purpose of this utility model is to provide a roller that is not only quiet and wear-resistant, but also easy to clean impurities in the track; another purpose of this utility model is to provide a high-speed material cart.

[0005] Technical solution: A roller, comprising: An aluminum wheel hub with mounting holes, wherein the aluminum wheel hub has an annular dovetail groove on its outer side; An elastic ring with an annular dovetail tenon, wherein the annular dovetail tenon and the annular dovetail groove are cast and connected, and the elastic ring is cast and connected to the outside of the aluminum wheel hub. A plurality of waist-shaped through holes are spaced apart on the aluminum wheel hub, and the spacing between adjacent waist-shaped through holes is equal.

[0006] Optional, also includes: A plurality of axially extending grooves spaced apart outside the aluminum hub; A plurality of axially extending blocks spaced apart within the elastic ring; The axial extension groove and the axial extension block are connected by casting.

[0007] Optionally, the spacing between adjacent axial extension slots is equal, and the spacing between adjacent axial extension blocks is equal.

[0008] Optionally, it also includes a plurality of circular through holes spaced apart from the aluminum hub, the circular through holes being located between adjacent waist-shaped through holes.

[0009] Optionally, the spacing between adjacent circular through holes is equal.

[0010] Optionally, adhesive is applied to both the outer surface of the aluminum wheel hub and the inner surface of the annular dovetail groove. The annular dovetail tenon and the annular dovetail groove are bonded together by casting with adhesive. The elastic ring is bonded to the outer surface of the aluminum wheel hub by casting with adhesive.

[0011] Optionally, the elastic ring is provided with a chamfered portion on the outside.

[0012] A high-speed material handling vehicle, including a roller.

[0013] Beneficial effects: (1) During production, the aluminum hub with an annular dovetail groove is first placed in the casting mold, and then the melt is poured into the casting mold. After cooling, the melt forms an annular dovetail tenon in the annular dovetail groove and an elastic ring on the outside of the aluminum hub, thus completing the casting process. This makes it easier to ensure the strong connection between the aluminum hub and the elastic ring. At the same time, since the annular dovetail tenon and the annular dovetail groove are connected by casting, it is easier to prevent the aluminum hub and the elastic ring from moving axially and radially relative to each other, further ensuring the strong connection between the aluminum hub and the elastic ring. This allows the elastic ring to fully utilize its advantages of low noise and good wear resistance, which helps to increase the service life of the roller in this solution. (2) When the roller of this scheme rolls on the track, the side wall of the aluminum hub will act like a "scraper" to scrape away the sand, iron filings and other impurities remaining in the track and contain them in the waist-shaped through hole, which makes it easier to clean the impurities from the waist-shaped through hole later and ensures that the roller rolls smoothly.

[0017] Example 1 like Figures 1-6 This embodiment provides a roller, including: an aluminum hub 1 with mounting holes 13, and an annular dovetail groove 11 on the outside of the aluminum hub 1; an elastic ring 2 with an annular dovetail tenon 21, the annular dovetail tenon 21 and the annular dovetail groove 11 are cast and connected, and the elastic ring 2 is cast and connected to the outside of the aluminum hub 1; and a plurality of waist-shaped through holes 14 spaced apart on the aluminum hub 1, the spacing between adjacent waist-shaped through holes 14 being equal.

[0018] Specifically, mounting hole 13 is used to connect with a related stainless steel shaft, facilitating the rotation of the aluminum hub 1 by the related stainless steel shaft; the aluminum hub 1 is used to roll within a related track; during production, the aluminum hub 1 with an annular dovetail groove 11 is first placed in a casting mold, and then the melt is poured into the casting mold. After cooling, the melt forms an annular dovetail tenon 21 within the annular dovetail groove 11 and an elastic ring 2 outside the aluminum hub 1, thus completing the casting process. This ensures a strong connection between the aluminum hub 1 and the elastic ring 2. At the same time, since the annular dovetail tenon 21 and the annular dovetail groove 11 are connected by casting, it helps to prevent axial and radial relative movement between the aluminum hub 1 and the elastic ring 2, further ensuring a strong connection between the aluminum hub 1 and the elastic ring 2. This allows the elastic ring 2 to fully utilize its advantages of low noise and good wear resistance, thus increasing the service life of the roller in this solution. The material of the elastic ring 2 can be thermoplastic polyurethane elastomer (TPU), etc.

[0019] When the rollers of this design roll on the track, the sidewall of the aluminum hub 1 acts like a "scraper," scraping away residual sand, iron filings, and other impurities from the track and accommodating them within the waist-shaped through-hole 14. This facilitates subsequent cleaning of impurities through the waist-shaped through-hole 14, ensuring smooth rolling of the rollers. The waist-shaped through-hole 14 also reduces weight and the amount of metal material used. Furthermore, it enhances heat dissipation. Structurally, the waist-shaped through-hole 14 combines rigidity and elasticity. Under load, the ribs between the waist-shaped through-holes 14 undergo slight elastic deformation, which helps absorb minor impacts and vibrations from the track, providing a smoother rolling experience. Since the spacing between adjacent waist-shaped through-holes 14 is equal, their distribution is uniform, resulting in good structural uniformity of the aluminum hub 1. The number of waist-shaped through-holes 14 is not limited; it can be three, four, etc., but three is preferred.

[0020] Furthermore, such as Figures 5-6 It also includes: a plurality of axial extension grooves 12 spaced apart outside the aluminum hub 1; a plurality of axial extension blocks 22 spaced apart inside the elastic ring 2; wherein the axial extension grooves 12 and the axial extension blocks 22 are cast and connected.

[0021] Specifically, since the axial extension groove 12 and the axial extension block 22 are cast and connected, it is easy to prevent the aluminum hub 1 and the elastic ring 2 from rotating relative to each other in the circumference, and further ensures the good connection between the aluminum hub 1 and the elastic ring 2.

[0022] Furthermore, such as Figures 5-6 The spacing between adjacent axial extension grooves 12 is equal, and the spacing between adjacent axial extension blocks 22 is equal.

[0023] Specifically, the equal spacing facilitates the uniform distribution of the axial extension grooves 12 and axial extension blocks 22, thereby ensuring the structural uniformity of the aluminum hub 1 and the elastic ring 2.

[0024] Furthermore, such as Figures 1-3 It also includes a number of circular through holes 15 spaced apart on the aluminum hub 1, with the circular through holes 15 located between adjacent waist-shaped through holes 14.

[0025] Specifically, the circular through hole 15 is used to reduce weight and the amount of metal material used. Since the circular through hole 15 is located between adjacent waist-shaped through holes 14, it is easy to make the distribution of the circular through hole 15 and the waist-shaped through hole 14 uniform and prevent mutual interference. The number of circular through holes 15 is not limited, but it is necessary to ensure that the number of circular through holes 15 and the number of waist-shaped through holes 14 are equal. It can be three, four, etc., preferably three.

[0026] Furthermore, such as Figures 1-3 The spacing between adjacent circular through holes 15 is equal.

[0027] Specifically, equal spacing helps to ensure good uniformity in the distribution of the circular through holes 15.

[0028] Furthermore, such as Figures 1-6 Adhesive is applied to both the outer surface of the aluminum hub 1 and the inner surface of the annular dovetail groove 11. The annular dovetail tenon 21 and the annular dovetail groove 11 are bonded together by casting with adhesive. The elastic ring 2 is bonded to the outer surface of the aluminum hub 1 by casting with adhesive.

[0029] Specifically, the adhesive is used to further increase the connection strength between the aluminum hub 1 and the elastic ring 2, and the adhesive can be a Chemlock series adhesive.

[0030] Furthermore, such as Figures 1-4 The elastic ring 2 has a chamfered part 23 on its outside.

[0031] Specifically, the chamfered portion 23 facilitates a smoother transition outside the elastic ring 2, preventing stress concentration.

[0032] This embodiment also provides a high-speed material cart, including a roller as described in this embodiment.

[0033] The above embodiments only illustrate several implementation methods of this utility model, and their descriptions are relatively specific and detailed, but they should not be construed as limiting the scope of this utility model patent. It should be noted that those skilled in the art can make various modifications and improvements without departing from the concept of this utility model, and these all fall within the protection scope of this utility model. Therefore, the protection scope of this utility model patent should be determined by the appended claims.
