Technical Field

[0001] This utility model relates to the field of electric hoist technology, and in particular to an online replacement device for an electric hoist using a ring track. Background Technology

[0002] In circular rail conveying scenarios, electric hoists are the core actuators for material handling and transmission, widely used in the production processes of industrial equipment such as shot blasting and spraying. They are often used in a coordinated manner by multiple hoists to complete continuous material conveying tasks. Their operation relies on the guide rail structure of the circular rail for movement. During long-term, high-frequency use, they are prone to failure due to factors such as mechanical wear and load fluctuations. At present, multi-set electric hoists are widely used in ring track conveying, especially in shot blasting and spraying equipment. However, electric hoists are bound to malfunction after long-term use. Whenever one set of electric hoists malfunctions, the line must be stopped for repairs before production can resume, which increases maintenance costs. Therefore, an online replacement device for electric hoists in ring tracks is proposed. Utility Model Content

The rail-changing carriage has two rotating shafts passing through both ends, and V-shaped rollers are mounted at both ends of the rotating shafts. The V-shaped rollers... The slotted section is secured to the angle steel guide rail; the front and rear rails are fixed at the bottom of the rail-changing vehicle frame respectively, and the front and rear rails are fixed by bolts.

[0006] In a preferred embodiment of the online rail-changing device for an electric hoist provided by this utility model, the positions of the front and rear rails on the rail-changing frame are controlled by the stroke of the cylinder.

[0007] In a preferred embodiment of the online track-changing device for electric hoists provided by this utility model, the V-groove of the V-shaped roller cooperates with the angle steel guide rail to prevent the track-changing vehicle frame from derailing due to shaking or uneven driving force.

[0015] To enable those skilled in the art to better understand the present invention, the technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort should fall within the protection scope of the present invention. Example

[0016] An online track-changing device using an electric hoist, characterized in that it comprises: a connecting fixed beam 1, a front limiter 2, an angle steel guide rail 3, an upper fixer 4, a guide rail support beam 5, V-shaped rollers 6, a track-changing carriage 7, a front rail 8, a rotating shaft 9, a cylinder 10, a cylinder tailstock 11, a rear rail 12, a rear limiter 13, and a conveying guide rail 14; the two ends of the connecting fixed beam 1 are respectively welded to the two ends of the guide rail support beam 5, and the front limiter 2 is welded to the upper two sides of the connecting fixed beam 1; one angle steel is welded to the upper part of the guide rail support beam 5, and another angle steel is fixed to the guide rail support beam 5 in the opposite direction by the upper fixer 4 and is symmetrical with the lower angle steel, together forming the angle steel guide rail 3; the track-changing carriage 7 is passed through by two rotating shafts 9 at both ends, and V-shaped rollers 6 are respectively installed at both ends of the rotating shafts 9, and the V-shaped grooves of the V-shaped rollers 6 are engaged at the angle steel guide rail 3; the track-changing carriage 7... The front rail 8 and rear rail 12 are fixed at the bottom front and rear respectively, and are fixed by bolts. Shims are placed between the front rail 8, rear rail 12 and the rail-changing frame 7. Cylinders 10 are mounted on both sides of one end of the rail-changing frame 7. The tail of the cylinder 10 is fixed by a cylinder tailstock 11 welded to the guide rail support beam 5. The guide rail support beam 5 has a rear limiter 13 on each side of the cylinder 10. The position of the front rail 8 and rear rail 12 on the rail-changing frame 7 is controlled by the stroke of the cylinder 10. The V-groove of the V-shaped roller 6 cooperates with the angle steel guide rail 3 to prevent the rail-changing frame 7 from derailing due to shaking or uneven driving force. The connecting fixing beam 1 works in conjunction with the front limiter 2. The cylinder 10 is used to drive the rail-changing frame 7 to move, thereby adjusting and aligning the positions of the front rail 8, rear rail 12 and the conveying guide rail 14. The upper fixing device 4... This is used to fix the angle steels arranged in opposite directions onto the guide rail support beam 5, so that the two angle steels are symmetrically arranged and together form the angle steel guide rail 3.

[0017] Preferably, the connecting fixed beam 1 and the guide rail support beam 5 are welded to form a stable frame, providing reliable structural support for the entire rail changing system and preventing shaking caused by the passage of the electric hoist or rail changing operation; the angle steel guide rail 3 is composed of two symmetrically arranged angle steels, which, together with the V-groove of the V-shaped roller 6, can precisely limit the movement trajectory of the rail changing frame 7, effectively preventing the rail changing frame 7 from derailing due to shaking or uneven driving force. At the same time, the rotating shaft 9 provides a stable installation base for the V-shaped roller 6, ensuring smooth rotation of the roller during the rail changing process, further improving the stability and safety of the system operation.

[0018] Preferably, the cylinder 10 serves as a driving component, enabling the rail-changing frame 7 to move flexibly. Combined with the fixing effect of the cylinder tailstock 11, this ensures stable transmission of the driving force from the cylinder 10. The front limiter 2 and the rear limiter 13 can respectively fine-tune the positions of the front rail 8 and the rear rail 12 when the cylinder 10 extends and retracts. Simultaneously, the shims between the front rail 8, the rear rail 12, and the rail-changing frame 7 can adjust the height of the rails. This dual adjustment mechanism ensures precise alignment of the front rail 8, the rear rail 12, and the conveying guide rail 14, preventing obstruction of the electric hoist's passage due to misalignment. This allows for smooth replacement of faulty electric hoists and smooth passage of normal electric hoists.

[0019] Preferably, the upper fixing device 4 can firmly fix the opposite angle steel to the guide rail support beam 5, forming the angle steel guide rail 3 without complex modifications to the guide rail support beam 5, simplifying the installation process; the front rail 8 and rear rail 12 are fixed to the rail changing frame 7 with bolts, making disassembly and assembly convenient and facilitating later maintenance or replacement. The design of these parts allows the system to be modified for equipment that has already undergone rail changing, significantly reducing the overall modification cost. At the same time, it eliminates the need to remanufacture complex guide rail structures, reducing guide rail compatibility problems caused by manufacturing errors and improving the applicability of the system in different ring rail scenarios.

[0020] The online replacement device for electric hoists on a ring track provided by this utility model operates as follows: Relying on the stable frame formed by the connecting fixed beam 1 and the guide rail support beam 5, and using the angle steel guide rail 3 as the moving guide base for the track replacement frame 7, the faulty electric hoist is replaced online through the drive of the cylinder 10 and the coordination of limit adjustment. When a set of electric hoists on the ring track malfunctions, the faulty hoist will enter the system area in the unloaded section of the ring track along the conveying guide rail 14; at this time, the cylinder 10 is started, and its tail is fixed by the cylinder tail seat 11 to ensure stable driving force, driving the track replacement frame 7 to move along the angle steel guide rail 3 through the V-shaped rollers 6 on the two end rotating shafts 9—the cooperation between the V-shaped groove of the V-shaped roller 6 and the angle steel guide rail 3 can prevent the track replacement frame 7 from shaking or derailing. During the extension of cylinder 10, the position of rear rail 12 can be finely adjusted by adjusting the front limiter 2, making rear rail 12 flush with the conveying guide rail 14. When cylinder 10 retracts, the position of front rail 8 can be finely adjusted by adjusting the rear limiter 13 on the side of rear rail 12. At the same time, the shims between front rail 8, rear rail 12 and rail changing frame 7 can adjust the height of the rails, ensuring that front rail 8, rear rail 12 and conveying guide rail 14 are vertically flush. After the rails are precisely aligned, the faulty electric hoist can smoothly enter front rail 8 or rear rail 12 to detach from the main ring rail, realizing online replacement and maintenance, while the remaining normal electric hoists can continue to operate along the original conveying guide rail 14, avoiding production line downtime.
