Technical Field

[0001] This utility model relates to the field of lifting machinery, specifically to a special safety protection device for preventing falls from single-girder electric hoists. Background Technology

[0002] The single-girder electric hoist fall protection device is a safety protection device used on electric hoist lifting equipment to prevent the load from accidentally falling and ensure the safety of operators. This device mainly monitors the operation of the electric hoist in real time through mechanical or electrical means. In the event of any abnormality, such as a broken wire rope or a loose hook, it can promptly activate the protection mechanism to prevent the load from falling.

[0003] According to the published specification of the electric hoist for a calcium carbide furnace with a single beam and nylon insulated roller (publication number: CN 213569296 U), it includes a connecting housing. Connecting ear plates are fixedly connected to the upper left and right sides of the connecting housing. Rollers are connected to the upper front and rear sides of the inner cavity of the connecting ear plates through bearings. A rotating roller is connected to the lower part of the inner cavity of the connecting housing through a connecting shaft. A spiral reinforcing plate is fixedly connected to the outer side of the rotating roller. An insulating sleeve is fixedly sleeved on the outer side of the rotating shaft roller.

[0004] The aforementioned method, which relies on the interaction between components such as the housing and rollers, is insufficient to prevent the electric hoist from suddenly falling. This increases the threat to operators and the surrounding environment, leading to a higher risk of injury, and requires improvement. Utility Model Content

[0005] This utility model proposes a special safety protection device for preventing single-girder electric hoists from falling, which solves the problem that the special safety protection devices for preventing single-girder electric hoists from falling in related technologies cannot prevent the electric hoist from falling suddenly.

[0007] Optionally, a housing is fixedly connected to the side of the frame, and a suspension rod is fixedly connected to the inner wall of the housing. The protective rope is in contact with the suspension rod, and the design of the housing facilitates wrapping one end of the protective rope around the suspension rod.

[0008] Optionally, two protective ropes, outer shells, and suspension rods are provided, and they are symmetrical to each other along the vertical central axis of the frame. The provision of two protective ropes helps to improve the stability of the electric hoist and prevent the electric hoist from tilting during use.

[0009] Optionally, the weight of the U-shaped lifting ring is set to three tons, and the interior of the welded seat and single beam includes steel bars with a diameter of 8 mm. This high-quality material design helps to improve the stability of the protection.

[0010] Optionally, a protective assembly is provided on the side of the frame. The protective assembly includes a support rod, one end of which is fixedly connected to the side of the frame and a motor. A horizontal plate is fixedly connected to the side of the frame, and a rotating rod is rotatably connected to the top of the horizontal plate. The output shaft of the motor is fixedly connected to one end of the rotating rod, and a protective cover is fixedly connected to the circumferential surface of the rotating rod. The protective cover partially covers the protective rope, the outer shell, and the U-shaped lifting ring for protection.

[0011] Optionally, the outer shell, U-shaped lifting ring, and protective rope are located on the displacement trajectory of the protective cover, and a switch is provided on the outer wall of the motor. The switch is designed to facilitate direct control of the motor.

[0012] Optionally, two support rods, motors, and protective covers are provided, and they are symmetrical to each other along the vertical central axis of the frame.

[0028] Example 1

[0029] Reference Figures 1-5 This is the first embodiment of the present invention, which proposes a special safety protection device for preventing falls of a single-beam electric hoist. The device includes a single beam 1, a welding seat 2 at the bottom of the single beam 1, and a safety protection device 3 at the top of the single beam 1. The safety protection device 3 includes a trolley drive wheel 31, the side of which is located on the side of the single beam 1. A trolley driven wheel 32 is located on the side of the single beam 1. A suspension shaft 33 is located at the bottom of the single beam 1. An electric hoist 34 is located on the side of the single beam 1. A frame 35 is located at the top of the single beam 1. A U-shaped lifting ring 36 is fixedly connected to the side of the frame 35. A protective rope 37 is located at one end of the U-shaped lifting ring 36. The end of the protective rope 37 away from the U-shaped lifting ring 36 is located on the side of the electric hoist 34.

[0030] A housing 39 is fixedly connected to the side of the frame 35. A suspension rod 38 is fixedly connected to the inner wall of the housing 39. A protective rope 37 is in contact with the suspension rod 38. The design of the housing 39 is conducive to wrapping one end of the protective rope 37 around the suspension rod 38.

[0031] There are two protective ropes 37, outer shell 39, and suspension rods 38, which are symmetrical to each other along the vertical central axis of the frame 35. The presence of two protective ropes 37 helps to improve the stability of the electric hoist 34 and prevents the electric hoist 34 from tilting during use.

[0032] The weight of the U-shaped lifting ring 36 is set at three tons. The interior of the welded seat 2 and the single beam 1 includes steel bars with a diameter of 8 mm. This high-quality material design helps to improve the stability of the protection.

[0033] In this embodiment, a welding seat 2 is first welded to the side of the suspension shaft 33 seat of the electric hoist 34 in a direction perpendicular to the suspension shaft 33. A fixing frame for the single-beam protection rope 37 of the electric hoist is then welded onto the welding seat 2, using 12mm diameter steel bars. An 8mm diameter steel wire rope is then used to tie the frame 35 of the protection rope 37 every 10cm with No. 14 iron wire. Both ends of the steel wire rope (made into rope knots according to the total length) are connected to the protection rope 37 using three-ton U-shaped lifting rings 36. The protection rope 37, like a safety belt, crosses the single beam 1 and moves with the hoist trolley. In case the hoist trolley's main or driven wheel derails or the suspension shaft 33 breaks, the electric hoist... In the event of a fall accident involving the electric hoist 34, the safety rope will hold the electric hoist 34 in place to prevent it from hitting the ground and injuring people. When the electric hoist 34 experiences a malfunction such as derailment of the main or driven wheels or breakage of the suspension shaft 33, the safety rope 37 can prevent the electric hoist 34 from falling suddenly, reducing the threat to operators and the surrounding environment. The safety rope 37 acts like a safety belt, effectively preventing the equipment from falling violently and reducing the risk of injury. By fixing the electric hoist 34 to the single beam 1, the safety rope 37 increases the stability of the equipment. When a sudden malfunction occurs, the free fall of the electric hoist 34 is stopped, reducing the damage to the equipment and thus extending its service life.

[0034] Example 2

[0035] Reference Figures 1-5 This is the second embodiment of the present invention. The difference between this embodiment and the first embodiment is that a protective component 4 is provided on the side of the frame 35. The protective component 4 includes a support rod 41. One end of the support rod 41 is fixedly connected to the side of the frame 35, and a motor 42 is fixedly connected to one end of the support rod 41. A horizontal plate 43 is fixedly connected to the side of the frame 35. A rotating rod 44 is rotatably connected to the top of the horizontal plate 43. The output shaft of the motor 42 is fixedly connected to one end of the rotating rod 44. A protective cover 45 is fixedly connected to the circumferential surface of the rotating rod 44. The protective cover 45 partially covers the protective rope 37, the outer shell 39, and the U-shaped lifting ring 36 for protection.

[0036] The outer casing 39, the U-shaped lifting ring 36, and the protective rope 37 are located on the displacement trajectory of the protective cover 45. A switch 46 is provided on the outer wall of the motor 42. The design of the switch 46 makes it convenient to directly control the motor 42.

[0037] There are two support rods 41, motors 42, and protective covers 45, which are symmetrical to each other along the vertical central axis of the frame 35. The two protective covers 45 can protect the protective ropes 37 on both sides at the same time, preventing them from being disturbed by the outside world during operation.

[0038] The protective cover 45 is located on the side of the frame 35, and the end of the protective rope 37 away from the U-shaped lifting ring 36 passes through the top of the outer shell 39. This design protects the protective rope 37 from the outer shell 39.

[0039] Compared to Embodiment 1, further, pressing switch 46 starts motor 42, causing motor 42 to rotate forward, which in turn drives rotating rod 44 to rotate forward at the top of horizontal plate 43. The rotation of rotating rod 44 in turn drives protective cover 45 to rotate forward, causing protective cover 45 to rotate towards the side closer to protective rope 37, covering the connection between protective rope 37 and U-shaped lifting ring 36, protecting protective rope 37 and preventing damage caused by interference at the work site. In the working environment, protective rope 37 is often exposed and easily affected by collisions and friction from external objects, which may lead to wear or damage. The cover 45 can effectively avoid external interference, protect protective rope 37 from damage, and ensure that it plays its due safety role. Protective rope 37 is a key component to prevent electric hoist 34 from falling. If protective rope 37 is damaged, the protective function may fail, increasing safety hazards. The design of protective cover 45 ensures that protective rope 37 is fully protected, avoiding accidental damage, thereby improving the overall safety during the operation.
