[0023] The following detailed, non-limiting description of the present invention, in conjunction with preferred embodiments and accompanying drawings, is provided. Obviously, the described embodiments are merely some, not all, of the embodiments of the present 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.

[0024] Please see Figures 1-4 The present invention provides a technical solution: a bridge crane with a cab fall prevention system, comprising an installation beam 1, an upper fixing member 2, a lower fixing member 3, a connecting chain 4, and a car 5. The upper fixing member 2 is located at the bottom of the installation beam 1, the lower fixing member 3 is installed below the upper fixing member 2, one end of the connecting chain 4 is connected to the upper fixing member 2, the other end of the connecting chain 4 is connected to the lower fixing member 3, and the car 5 is located at the bottom of the lower fixing member 3.

[0025] The upper fixing component 2 includes an L-shaped plate 201, a first fastening nail 202, a second fastening nail 203, a triangular block 204, and an upper connecting hole 205. The first fastening nail 202 passes through the L-shaped plate 201 and is screwed to the mounting beam 1. The second fastening nail 203 is located on one side of the bottom of the L-shaped plate 201. The triangular block 204 is fixedly connected to the outside of the L-shaped plate 201. The upper connecting hole 205 is opened inside the triangular block 204. The triangular block 204 adopts full welding technology and beveling double-sided welding to ensure that the load-bearing capacity of the steel chain 401 is more than twice that of the upper fixing component with the self-weight of the cab, thus ensuring the strength of use.

[0026] The lower fixing component 3 includes a reinforcing beam 301, a mounting hole 302, a side plate 303, and a lower connecting hole 304. The mounting hole 302 is opened at one end of the reinforcing beam 301. The side plate 303 is fixedly connected to both sides of the reinforcing beam 301. The lower connecting hole 304 is opened inside the side plate 303. One end of the second fastening nail 203 passes through the L-shaped plate 201 and is screwed into the mounting hole 302. By connecting the L-shaped plate 201 and the reinforcing beam 301, the connection between the mounting beam 1 and the car 5 is strengthened, ensuring the safe use of the car 5. The bottom of the reinforcing beam 301 is fixedly connected to the top of the car 5, ensuring the stable connection between the car 5 and the mounting beam 1.

[0027] The connecting chain 4 includes a steel chain 401, a connecting pipe 402, and a clamping plate 403. The connecting pipe 402 is fixedly connected to both ends of the steel chain 401. The steel chain 401 passes through the upper connecting hole 205 and the lower connecting hole 304. By connecting the steel chain 401 to the upper connecting hole 205 and the lower connecting hole 304, and reinforcing it with the clamping plate 403, the triangular block 204 and the side plate 303 are connected. As a fall protection device for a fixed cab, the size of the clamping plate 403 is larger than the size of the upper connecting hole 205 and the lower connecting hole 304 for the effect of clamping and reinforcement, ensuring the firm use of the steel chain 401. The triangular block 204 and the side plate 303 are made of 20 mm steel plates to ensure the structural strength of the device.

[0028] The top of the car 5 is equipped with four side plates 303, totaling four suspension points. This allows for prediction of which side's fixing bolts will fail when the cab's fasteners fail, while also enabling the anti-fall device to bear the weight of the cab and prevent falls, thus improving the safety factor of the fixed cab of the bridge crane.

[0029] The car 5 and the mounting beam 1 are installed. The first fastening nail 202 and the second fastening nail 203 are connected to the mounting beam 1 and the L-shaped plate 201 respectively, so that the upper fixing part 2 is installed between the mounting beam 1 and the car 5. Then, the steel chain 401 passes through the triangular block 204 and the side plate 303 to connect the triangular block 204 and the side plate 303. The connection between the mounting beam 1 and the connecting chain 4 is ensured by the L-shaped plate 201 and the reinforcing beam 301. The steel chain 401 passes through the upper connecting hole 205 and the lower connecting hole 304 to prevent secondary falls and ensure the safety of the car 5.
