Description

Technical Field

[0001] This utility model relates to the field of fall protection equipment technology, and in particular to a device for preventing electric hoists from falling from heights. Background Technology

[0002] Among numerous enterprises and repair shops, electric hoists, as small lifting equipment, are widely used for critical tasks such as hoisting raw materials due to their flexibility, light weight, and ease of operation. However, their use presents many safety hazards, especially older electric hoists, which often have significant design flaws, lacking fall protection devices on the trolley beam and travel motor. Although newer electric hoists have been equipped with fall protection devices on the trolley beam in recent years, protective measures for the travel motor remain lacking. In actual working scenarios, continuous operation leads to loose screws, equipment aging, and increased gear clearance. Coupled with improper operation by some personnel (such as pulling or lifting at an angle), these factors combine to create a significant risk of electric hoists falling from heights during use. An accident in such a case would result in serious personal injury and substantial economic losses. Utility Model Content

[0003] The purpose of this utility model is to provide a device to prevent electric hoists from falling from heights, so as to solve the problems mentioned in the background art.

[0004] To achieve the above objectives, the technical solution adopted by this utility model is as follows: A device for preventing electric hoists from falling from heights includes an anti-detachment device installed at the connection between the original main beam and the travel motor slot. The anti-detachment device includes two channel steels and a connecting rod, which are connected by bolts and buffer washers.

[0005] The two channel steels are installed in the original beam and the travel motor slot.

[0006] The connecting rod is made of high-strength steel.

[0007] The mounting base for the walking motor is equipped with a hydraulic damping buffer and a mechanical ratchet locking mechanism.

[0008] The response time of the hydraulic damping buffer is less than 50ms.

[0009] In summary, due to the adoption of the above technical solution, the beneficial effects of this utility model are: This invention combines mechanical reinforcement with a dynamic buffer safety protection system, breaking through the traditional single protection mode. Its application reduces the overall risk of electric hoists falling from heights by 95%. Double channel steel and high-strength connecting rods form a rigid support frame. The channel steel and main structure are connected using bolts and buffer washers, significantly reducing the wear rate of critical structures, beams, and the travel motor slots. Simultaneously, key bolt nodes are visualized, avoiding "blind inspection" in traditional maintenance, reducing ineffective disassembly and inspection, shortening downtime, extending equipment maintenance cycles, reducing annual maintenance costs, and improving overall production efficiency. Furthermore, it reduces metal debris pollution caused by equipment failure, aligning with the company's sustainable development goals. Attached Figure Description

[0014] To make the objectives, technical solutions, and advantages of the embodiments of this utility model clearer, the technical solutions of the embodiments of this utility model will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this utility model, and not all embodiments. The components of the embodiments of this utility model described and shown in the accompanying drawings can generally be arranged and designed in various different configurations.

[0015] Therefore, the following detailed description of the embodiments of the present invention provided in the accompanying drawings is not intended to limit the scope of the claimed invention, but merely to illustrate selected embodiments of the invention. All other embodiments obtained by those skilled in the art based on the embodiments of the present invention without inventive effort are within the scope of protection of the present invention.

[0016] like Figure 1-4As shown, this utility model provides a device to prevent electric hoists from falling from heights, comprising the following: Two channel steels measuring 220mm×100mm×40mm are designed and installed within the existing main beam and the travel motor slot, and connected by a high-strength steel connecting rod to form a stable anti-detachment device, dispersing load-bearing stress and preventing localized fractures due to metal fatigue. This innovative design effectively avoids electric hoist falls caused by equipment structural defects, equipment aging, or improper operation, achieving a dual improvement in production efficiency and safety. Simultaneously, a hydraulic damping buffer (response time <50ms) and a mechanical ratchet locking mechanism are installed at the travel motor mounting base, forming a "soft landing + hard locking" dual guarantee, ensuring an 80% reduction in fall impact force. Furthermore, the channel steel and the main structure are connected using bolts and buffer washers to avoid frictional wear, extend service life, and reduce fall impact force by 20%. The channel steel and connecting rod use a quick-release structure with bolts and buffer washers, facilitating regular inspection and replacement; key bolt nodes are visualized, simplifying maintenance procedures and reducing downtime. The hydraulic damping buffer and mechanical ratchet locking mechanism are both ready-made products that can be purchased directly from the market. The bolts are headless bolts, which, together with nuts and buffer washers, can intuitively show the connection status, extend the bolt life, and reduce the need for frequent maintenance caused by loosening and corrosion.

[0017] One of our company's workshops implemented a significant technical improvement to the safety features of its CD1-1-18 model 2T electric hoist. This improvement significantly enhanced the stability of the equipment's operation, reducing the overall risk of the electric hoist falling from heights by 95%, and also significantly reduced maintenance time costs for on-site personnel. This innovative measure not only improved the hoist's operational reliability but also provided a robust safety measure for material handling in the workshop, reducing the risk of employee injury due to accidents.
