Description

Technical Field

[0001] This utility model relates to the field of rubber track technology, and in particular to a rubber track for an aerial work platform. Background Technology

[0002] Rubber tracks are a type of ring-shaped rubber belt made of rubber and metal or fiber skeleton materials. They are mainly used for the walking parts of tracked machinery or vehicles. The rubber tracks of aerial work platforms are usually used for high-altitude operations, mainly for the maintenance, installation, and cleaning of buildings such as buildings, hotels, and urban complexes, both indoors and outdoors. The rubber tracks play a key role in walking and supporting, enabling aerial work platforms to work stably in various complex terrains and environments.

[0003] To this end, patent CN221563266U discloses a rubber track, specifically relating to the field of rubber track technology. The track includes a rubber track body with multiple grooves at the top center. Each groove has metal teeth on both its front and rear sides. These metal teeth are arranged in a linear array on the top surface of the rubber track body. Multiple mounting cavities are formed inside the rubber track body, and each cavity contains a reinforcing rib. This invention uses reinforcing ribs, ring plates, support rods, and steel rings to provide pressure resistance within the rubber track body, thereby improving its pressure resistance and service life. Multiple first steel wires enhance the strength of the rubber track body, and the fixation of second steel wires to the first wires improves the connection between the metal teeth and the rubber track body. The use of multi-comb warp-knitted monofilament mesh as a wear-resistant layer improves the wear resistance and strength of the rubber track body surface.

[0004] The aforementioned rubber track uses a multi-comb warp-knitted monofilament mesh as a wear-resistant layer to improve the wear resistance and strength of the main surface of the rubber track. However, during the operation of the aerial work platform, the multi-comb warp-knitted monofilament mesh wear-resistant layer increases the friction between the main body of the rubber track and the building, which can cause significant damage to the contact surface between the main body of the rubber track and the building. Furthermore, the rubber track has poor shock resistance and insufficient grip, making it unsuitable for use. Utility Model Content

[0005] The purpose of this utility model is to provide a rubber track for aerial work platforms, in order to solve the defects of existing rubber tracks for aerial work platforms, which have poor shock resistance and grip.

[0006] To solve the above-mentioned technical problems, this utility model provides the following technical solution: a rubber track for an aerial work platform, comprising an outer rubber layer and an inner rubber layer;

[0007] An inner rubber layer is fixed to one side of the outer rubber layer. Anti-slip grooves are evenly provided on both sides of the outer wall of the outer rubber layer. A groove is provided at the middle position of the outer wall of the outer rubber layer. Connecting blocks are evenly fixed inside the groove, and through grooves are provided inside the outer rubber layer between adjacent connecting blocks.

[0008] Both sides of the outer wall of the inner rubber layer are chamfered, and a second reserved groove is evenly provided at the middle position of the outer wall of the inner rubber layer. A first reserved groove is provided inside the inner rubber layer on both sides of the second reserved groove, and teeth are fixed on the outer wall of the inner rubber layer between adjacent first reserved grooves.

[0009] The inner rubber layer is fixed with a transmission rib plate, and the outer rubber layer is evenly fixed with steel cords on both sides.

[0010] Preferably, the anti-slip grooves are in the shape of a "K" and are interconnected.

[0011] Preferably, the connecting blocks and through slots are distributed at equal intervals on the inner wall of the groove.

[0012] Preferably, the through groove is X-shaped and penetrates both the outer rubber layer and the inner rubber layer.

[0013] Preferably, the second reserved groove corresponds to the position of the through groove.

[0014] Preferably, the steel cord is located inside the outer rubber layer on the side close to the inner rubber layer.

[0015] Preferably, the steel cords are distributed at equal intervals on both sides inside the outer rubber layer.

[0016] The advantages of the rubber track for the aerial work platform provided by this utility model are as follows:

[0017] By incorporating anti-slip grooves, the "K"-shaped anti-slip grooves are distributed in a continuous manner on both sides of the outer wall of the outer rubber layer, providing excellent shock absorption in both longitudinal and lateral directions. This improves the shock resistance and anti-slip properties of the aerial work platform's rubber tracks, making the tracks have stronger grip, better anti-slip properties, and making driving the aerial work platform smoother and safer.

[0018] The track is equipped with transmission stiffeners, which are located inside the inner rubber layer and serve to engage, guide, and transmit power. The outer side of the transmission stiffeners uses steel cords as a skeleton layer to bear tension and transmit power. Attached Figure Description
