It also solves the problem that falling during the operation greatly endangers the personal safety of the operators, improves the safety of maintenance operations and reduces the cost of maintenance operations.

[0004] The utility model solves the technical problem by adopting the following technical scheme: a safety protection device for a herringbone ladder, which is provided with a herringbone ladder, characterized in that an anti-skid pad is installed at the foot of the herringbone ladder, the lower end of the step of the herringbone ladder is fixed by a step support frame, a limit bracket is provided on the herringbone ladder, a handrail and a guardrail are fixed around the herringbone ladder, an anti-skid pedal is installed at the upper end of the herringbone ladder, tripod legs are arranged around the herringbone ladder, the tripod legs can be adjusted in length, and the bottom end of the tripod legs is installed The tripod has anti-skid foot pads and a limit safety chain, the top of the tripod legs are connected through a tripod top frame, a tripod opening limiter and a tripod leg pin, the lower end of the tripod top frame is fixedly installed with a tripod lifting ring, and a pulley block is installed at the lower end of the tripod lifting ring. A self-locking winch and a winch handle are installed on one of the tripod legs, one end of the winch wire rope is connected to the self-locking winch, and the other end passes through the pulley block and is connected to the winch safety hook, and the lower end of the winch safety hook is connected to a five-point safety belt.

[0005] The beneficial effects of the utility model are that the safety risks caused by the difficulty of climbing are reduced and the work efficiency is improved by installing anti-skid pedals, anti-skid mats and pedal support frames, and the cooperation of triangular legs, self-locking winch, winch wire rope, pulley block and five-point safety belt ensures that the operators will not fall and the personal safety of the operators is guaranteed. BRIEF DESCRIPTION OF THE DRAWINGS

[0006] The present invention is further described below in conjunction with the accompanying drawings and embodiments.

[0007] Figure 1This is a schematic diagram of the structure of the utility model

[0008] In the figure, 1. a herringbone ladder, 2. anti-skid mat, 3. a herringbone ladder pedal, 4. pedal support frame, 5. limit bracket, 6. handrail, 7. guardrail, 8. anti-skid pedal, 9. tripod legs, 10. tripod anti-skid pads, 11. limit safety chain, 12. tripod top frame, 13. tripod opening limiter, 14. tripod leg pin, 15. tripod lifting ring, 16. self-locking winch, 17. winch handle, 18. winch wire rope, 19. pulley block, 20. winch safety hook, 21. five-point safety belt. DETAILED DESCRIPTION

[0009] like Figure 1 , a herringbone ladder 1 is provided, an anti-skid pad 2 is installed at the foot of the herringbone ladder 1, the lower end of the herringbone ladder pedal 3 is fixed by a pedal support frame 4, a limiting bracket 5 is provided on the herringbone ladder 1, a handrail 6 and a guardrail 7 are fixed around the herringbone ladder 1, an anti-skid pedal 8 is installed on the upper end of the herringbone ladder 1, and a tripod leg 9 is provided around the herringbone ladder 1. The tripod leg 9 can be adjusted in length, and a tripod anti-skid foot pad 10 and a limiting safety chain 11 are installed at the bottom of the tripod leg 9. The top of the tripod leg 9 is fixed by a tripod The tripod top frame 12, the tripod opening limiter 13 and the tripod leg pin 14 are connected, the tripod top frame 12 is fixedly installed at the lower end of the tripod ring 15, and the pulley block 19 is installed at the lower end of the tripod ring 15. A self-locking winch 16 and a winch handle 17 are installed on one of the tripod legs 9. One end of the winch wire rope 18 is connected to the self-locking winch 16, and the other end passes through the pulley block 19 and is connected to the winch safety hook 20. The lower end of the winch safety hook 20 is connected to the five-point safety belt 21.

[0010] When the utility model is used, the climbing operator moves the herringbone ladder 1 to the designated working place, opens the herringbone ladder 1 to the maximum limit position of the limit bracket 5, adjusts the height of the tripod legs 9 to meet the working requirements, and places the tripod legs 9 around the herringbone ladder 1. The tripod legs 9 play a stabilizing and limiting role under the cooperation of the tripod leg pins 14, the tripod top frame 12, the tripod anti-skid foot pads 10, the tripod opening limiter 13 and the limit safety chain 11. The climbing operator wears the five-point safety belt 21 and climbs step by step along the herringbone ladder pedal 3 to the anti-skid pedal 8. The pedal support frame 4 plays a role in the herringbone ladder pedal 3. The guardrail 7 and the handrail 6 play a supporting role. The anti-slip pad 2 of the herringbone ladder 1 contacts the ground under the action of gravity, generating a large friction force to prevent the herringbone ladder 1 from moving. The on-site supervisor adjusts the self-locking winch 16 through the winch handle 17 to drive the winch wire rope 18 according to the height position of the climbing operator. Through the pulley group 19 and the tripod ring 15, the winch safety hook 20 moves downward. The climbing operator connects the winch safety hook 20 with the five-point safety belt 21, which plays a good protective role when the climbing operator accidentally falls, solves the risk of falling during the climbing operation of the herringbone ladder 1, and eliminates the hidden dangers essentially.
