Description

Technical Field

[0001] The utility model belongs to the technical field of cantilever bucket wheel stacker and reclaimer systems, in particular to a cantilever bucket wheel stacker and reclaimer driving platform protection device. Background Art

[0002] Bucket wheel stacker reclaimer is suitable for long material yards. It is a large-scale bulk material loading and unloading equipment with high efficiency and continuous operation. It is mainly used in coal and ore storage yards in industries such as power, metallurgy, coal, building materials and chemicals. Bucket wheel stacker reclaimer has the characteristics of large turning radius, high production efficiency, low energy consumption and high environmental protection. Due to the different ground conveying system processes, arm bucket wheel stacker reclaimer can be designed into different tail car models.

[0003] The cantilever bucket wheel stacker and reclaimer is mainly composed of bucket wheel mechanism, cantilever belt conveyor, upper metal structure, turntable, portal seat, slewing mechanism, tail car, auxiliary structure, track system, lubrication system and control room.

[0004] Due to the particularity of the material stacking type, during the cantilever bucket wheel stacker and reclaimer's material reclaiming process, the bucket wheel driving platform (i.e., the control room) cannot observe the entire surrounding environment due to its field of vision. Therefore, the surrounding area and guardrails are often squeezed and deformed by the materials, and even the bucket wheel driving platform is damaged, causing damage to the cantilever bucket wheel stacker and reclaimer, while also reducing the efficiency of the cantilever bucket wheel stacker and reclaimer.

[0008] Moreover, the protection platform includes a cylinder, a guardrail, a terminal mechanical stopper and a basic stop block, wherein the cylinder is installed at the bottom of the bucket wheel driving platform, and the output end of the cylinder is connected to the guardrail. The guardrail is used to displace the bucket wheel driving platform when it is squeezed by materials during the material picking process. At the same time, the cylinder slows down the movement speed of the bucket wheel driving platform, thereby preventing the bucket wheel driving platform from being squeezed by materials during the material picking process and deforming. A terminal mechanical stopper is installed on the side of the output end of the cylinder close to the guardrail.

[0009] Moreover, a basic stop block is installed on the side of the bottom of the protective platform. The basic stop block is used to cooperate with the terminal mechanical stopper to limit the movement of the guardrail to prevent the movement of the guardrail from damaging the bucket wheel drive platform and the cylinder.

[0010] Moreover, the guardrail is in an arc shape, and the arc-shaped guardrail can protect the left side, right side and rear of the bucket wheel driving platform all year round, while preventing the guardrails on the adjacent two sides from colliding with each other.

[0011] Moreover, the protection platform also includes an infrared anti-collision travel switch, wherein the infrared anti-collision travel switch is arranged on the cylinder housing, the infrared anti-collision travel switch is arranged toward the guardrail, the internal passage of the infrared anti-collision travel switch is installed on the power supply circuit of the bucket wheel driving platform, and the internal switch is a normally closed switch.

[0012] The advantages and positive effects of the utility model are:

[0017] The utility model is further described in detail below with reference to the accompanying drawings.

[0018] A cantilever bucket wheel stacker and reclaimer driving platform protection device, such as Figure 1As shown, it is installed on the bucket wheel driving platform 2, and in front of the bucket wheel driving platform is the bucket wheel machine cantilever 1, including a protective platform 5, wherein the protective platform is arranged on the left side, right side and rear of the bucket wheel driving platform to prevent the bucket wheel driving platform from being squeezed and deformed by the materials during the material taking process.

[0019] The protection platform includes a cylinder 3, a guardrail 4, a terminal mechanical stopper 6 and a basic stop block 7, wherein the cylinder is installed at the bottom of the bucket wheel driving platform, and the output end of the cylinder is connected to the guardrail. The guardrail is used to displace the bucket wheel driving platform when it is squeezed by materials during the material picking process. At the same time, the cylinder slows down the movement speed of the bucket wheel driving platform, thereby preventing the bucket wheel driving platform from being squeezed by materials during the material picking process and deforming. A terminal mechanical stopper is installed on the side of the output end of the cylinder close to the guardrail.

[0020] A basic stop block is installed on the side of the bottom of the protective platform. The basic stop block is used to cooperate with the terminal mechanical stopper to limit the movement of the guardrail to prevent the movement of the guardrail from damaging the bucket wheel drive platform and the cylinder.

[0021] The guardrail is in an arc shape, which can protect the left side, right side and rear of the bucket wheel drive platform all year round, while preventing the guardrails on the adjacent sides from colliding with each other.

[0022] The protection platform also includes an infrared anti-collision travel switch 8, wherein the infrared anti-collision travel switch is arranged on the cylinder housing, the infrared anti-collision travel switch is arranged toward the guardrail, the internal passage of the infrared anti-collision travel switch is installed on the power circuit of the bucket wheel driving platform, and the internal switch is a normally closed switch.

[0023] The working principle of the utility model is:

[0024] The three sides of the bucket wheel driving platform of the bucket wheel excavator are respectively arranged with protective platforms. When the bucket wheel excavator is retrieving materials, the driving platform will move with the left and right swing of the cantilever. During this process, once the guardrail is squeezed by the higher material, the guardrail will shrink inward along the corresponding force direction to prevent the equipment from being deformed by force. When the squeezing force disappears, the guardrail will return to its original position under the push of the cylinder.

[0025] At the same time, once the cylinder's inward contraction stroke reaches the distance set by the infrared anti-collision stroke switch, the infrared anti-collision stroke switch cuts off the power supply of the bucket wheel drive platform, and the bucket wheel drive platform stops moving. When the cylinder contracts beyond the limit stroke, the terminal mechanical stopper installed on the cylinder collides with the basic stopper installed on the drive platform, forcing the cylinder to stop contracting, thereby protecting the cylinder.

[0026] It should be emphasized that the embodiments described in the present invention are illustrative rather than restrictive. Therefore, the present invention includes but is not limited to the embodiments described in the specific implementation manner. Any other implementation manners derived by those skilled in the art based on the technical solution of the present invention also fall within the scope of protection of the present invention.
