Description

Technical Field

[0001] This invention relates to the field of belt replacement, and discloses a large-angle belt replacement device and process. Background Technology

[0002] The steep-angle belt conveyor is a new type of continuous conveying equipment. It features a large conveying capacity (1.5 to 2 times higher than other conveyors), strong versatility (basic components are the same as general-purpose belt conveyors), and a wide range of applications (suitable for conveying materials with a particle size not exceeding 550mm, such as crushed stone, limestone, coal, sand, clay, sintered sand powder, sawdust, and grain). Currently, existing enclosed steep-angle belt conveyor systems have a fixed inspection door and electric hoist at the top of the belt. When the steep-angle belt needs replacement, this fixed inspection door is opened, and the belt is lifted in and out with the help of the electric hoist and crane. However, due to the long length and large angle of the steep-angle belt, using the original lifting equipment to lift it from the top of the belt is not only difficult, requires more personnel, has a longer construction time, and higher maintenance costs, but also reduces production efficiency and may even affect normal production to some extent.

[0003] To address the aforementioned problem that the belt is positioned below the idler rollers by the operator's hands, making operation inconvenient, a large-angle belt replacement device and process are provided. Summary of the Invention

[0004] The purpose of this invention is to address the above-mentioned problems by providing a large-angle belt replacement device and process.

[0005] The objective of this invention is achieved as follows: a large-angle belt replacement device includes a large-angle belt and a crane body (1) located on one side of the large-angle belt. The crane body (1) includes a crane body (2), and the crane body (2) includes a steel cable (3). A connecting plate (4) is fixedly connected to the bottom of the steel cable (3). An adjustment mechanism is provided at the bottom of the connecting plate (4). Connecting blocks (5) are fixedly connected to both sides of the bottom of the adjustment mechanism. A rotating shaft (6) is rotatably connected to the opposite side of the two connecting blocks (5) through bearings. A limit mechanism is provided on one side of the rotating shaft (6).

[0006] The adjustment mechanism includes an electric slide rail (7) fixedly connected to the bottom of the connecting plate (4). Electric sliders (8) are slidably connected to the inner walls on both sides of the electric slide rail (7).

[0007] The limiting mechanism includes two symmetrically distributed limiting rods (9), and limiting ports (10) are opened on the opposite sides of the two connecting blocks (5). Several circularly arranged and evenly distributed limiting grooves (11) are opened on the opposite sides of the two rotating shafts (6). The inner walls of the limiting grooves (11) and the inner walls of the limiting ports (10) are in sliding fit with the limiting rods (9).

[0008] The limiting rod (9) is inclined, and the lower end of the limiting rod (9) faces the belt with a large inclination angle.

[0009] The surface of the rotating shaft (6) is provided with several evenly distributed rolling grooves (12), and the inner wall of the rolling grooves (12) is rotatably connected to rolling balls (13).

[0010] The bottom corner of the crane body (1) is fixedly connected to an installation block (14), and the bottom of the installation block (14) is rotatably connected to a rotating wheel (15) via a bearing.

[0011] A handle (16) is fixedly connected to one side of the crane body (1).

[0012] An electric telescopic rod (17) is fixedly connected to the top of the crane body (1), and a fixing plate (18) is fixedly connected to one end of the piston rod of the electric telescopic rod (17), and the fixing plate (18) is fixedly connected to the crane body (2).

[0013] The bottom of the fixed plate (18) and one side of the piston rod of the electric telescopic rod (17) are fixedly connected to the same support rod (19).

When the belt is inserted, the belt can extend in coordination with the rotation of the rotating shaft, which facilitates the installation of the belt. Therefore, it can achieve the effect of facilitating operation by workers. Attached Figure Description

When the belt is inserted, the belt can extend in coordination with the rotation of the rotating shaft, which facilitates the installation of the belt. Therefore, it achieves the effect of facilitating operation by workers.

[0024] In a preferred embodiment, the adjustment mechanism includes an electric slide rail fixedly connected to the bottom of the connecting plate, and electric sliders are slidably connected to the inner walls on both sides of the electric slide rail.

[0030] In a preferred embodiment, the surface of the rotating shaft is provided with a plurality of evenly distributed rolling grooves, and the inner wall of the rolling grooves is rotatably connected to rolling balls.

[0031] By adopting the above technical solution, the rolling ball can rotate within the rolling groove, which makes it easy for workers to control the feeding distance of the belt. That is, holding the belt will stop feeding it, and releasing it will allow the belt to slide down under the action of the rolling ball.

[0032] In a preferred embodiment, a mounting block is fixedly connected to the bottom corner of the crane body, and a rotating wheel is rotatably connected to the bottom of the mounting block via a bearing.

[0033] By adopting the above technical solution, the rotating wheels facilitate the movement of the crane body.

[0034] In a preferred embodiment, a handle is fixedly connected to one side of the crane body.

[0043] S3: New Belt Introduction: Cut off eight hoppers at the red line at the tail end. Use the crane body to guide the new belt and overlap it with the old belt. Cut the old belt at the tail end and let it hang down to the waste hopper. Manually start the belt to bring it in 5-meter increments. Install a winch on the east side of the waste hopper to pull out the old belt (in sync with the new belt introduction rhythm) until the new belt is completely introduced. Secure one clamp at the 1000 pressure pulley, remove the 630 return pulley, adjust the 630 driven pulley (spiral tensioning device) to the maximum position for vulcanization, and install and position another belt clamp.

[0047] In this invention, during use, the crane body is moved to the vicinity of the large-angle belt, and then the electric slide rail is activated. The electric slider causes the connecting block to move, and the movement of the connecting block makes the distance between the opposite sides of the two rotating shafts greater than the width of the belt. Then, the electric telescopic rod is activated, and the piston rod of the electric telescopic rod causes the rotating shaft to descend. When the rotating shaft is adjusted into the gap of the belt, the electric slide rail is activated again, at which point the electric slide rail can bring the two rotating shafts closer to each other. When the rotating shaft is below the belt, the electric telescopic rod is activated, at which point the rotating shaft can lift the belt. When the belt is inserted, the belt can extend in coordination with the rotation of the rotating shaft, which facilitates the installation of the belt. Therefore, it can achieve the effect of facilitating operation by workers.
