Description

TECHNICAL FIELD

[0001] The application belongs to the technical field of electric hoist, more specifically, relates to a stable electric hoist capable of preventing falling. BACKGROUND

[0002] In the field of high-altitude heavy lifting, traditional lifting equipment and technology have many safety hazards and stability problems, which seriously affect the safety and reliability of lifting operations.

[0003] Whole moving stability problem

[0004] When the traditional lifting equipment moves on the suspended support, it lacks effective stability mechanism. During the movement driven by the driving device, it is easy to shake or even lose balance, increasing the risk of falling. For example, only relying on the simple contact of the driving wheel with the support, when lifting heavy objects, the overall center of gravity of the equipment changes, it is difficult to maintain stable movement, once shaking occurs, it may cause the heavy object to fall, causing serious threat to the personnel and equipment below.

[0005] Rope extension and retraction stability problem

[0006] Rope shaking: during the retraction or extension of the rope, the traditional equipment lacks good rope stability structure. Under the action of gravity and inertia in the lifting process, the rope is easy to shake with large amplitude, which not only affects the accuracy of lifting, but also may cause the rope to collide and wear with other parts due to shaking, shorten the service life of the rope, and even cause the rope to break, causing heavy object falling accident.

[0007] Rope storage and stability: for the retracted rope, the traditional equipment usually lacks effective storage and stability measures. The rope is randomly stacked or simply stored, which may cause entanglement, knotting and other problems during reuse, affecting the normal extension and retraction of the rope, and unable to guarantee the stability of the rope during storage, increasing the safety hazards in the lifting process.

[0008] Pull hook and connection stability problem

[0009] Pull hook stability: the traditional pull hook lacks stability when lifting high-altitude heavy objects. The connection between the pull hook and the rope may not be stable enough, and under the action of the weight of the heavy object, the pull hook is easy to shake, deviate or even fall off, which cannot reliably hook the heavy object, causing the heavy object to fall accidentally.

[0010] Connection structure stability: the connection structure between the components of the lifting equipment is often not reasonably designed. For example, the main support frame and the pull hook main frame may be rigidly connected, which may cause hard damage between metal components during lifting due to the swing of the heavy object and the vibration of the equipment, reducing the strength and stability of the connection structure, increasing the risk of equipment failure and heavy object falling.
