The technical scheme of the utility model is that:

A safety ladder used in a tower barrel comprises a climbing ladder, the climbing ladder comprises two holding rods fixedly connected to the inner side wall of the tower barrel, a plurality of pedals are arranged between the holding rods at equal intervals, the middle of each pedal is arranged to be concave, a -end fixing rod vertically and fixedly connected to the top of the tower barrel is arranged on the front side of the climbing ladder, a safety device capable of moving up and down along the direction of the fixing rod is arranged on the fixing rod, a through hole used for being matched with the fixing rod is formed in the safety device in a penetrating mode, a rope used for being connected to a human body is arranged on the outer side of the safety device, a plurality of tooth grooves are sequentially formed in the surface of the fixing rod from top to bottom, a gear is arranged in the safety device at the position corresponding to the tooth grooves, a forward and reverse motor is connected to the right side of the gear, the forward and reverse motor is fixedly connected to the safety device, a switch button corresponding to the forward and reverse motor is arranged outside the safety device, a storage battery and a storage battery used for supplying power to the forward and reverse motor are arranged in the safety device, a braking shaft is fixedly connected.

The number of turns of the self-locking spring is at least 12.

And a charging port corresponding to the storage battery and the standby storage battery is arranged on the outer side of the safety device.

The utility model has the advantages that:

before the utility model is used, only the rope on the safety device needs to be checked, which is more convenient and faster compared with the traditional check; when the climbing safety device is used, when an operator climbs, firstly, a rope on the safety device is connected to the operator, then the forward and reverse rotating motor is started, the safety device moves upwards in a matching way with a tooth groove on the fixed rod through the internal gear, the rotating directions of the gear and the brake shaft are opposite to the rotating direction of the self-locking spring, the self-locking spring is in a loosening state, and the resistance generated to the rotation of the gear is relatively small; when an operator slips carelessly, the safety device can be pulled down to cause the gear to rotate reversely rapidly, the rotating direction of the gear and the brake shaft is the same as the rotating direction of the self-locking spring, the self-locking spring can quickly hold the brake shaft tightly, large resistance is generated to the gear instantly, the gear stops rotating, and a timely braking effect is achieved; when operating personnel moved down, the positive and negative motor reversal of rotating drove the gear, and the gear direction of rotation is the same with the auto-lock spring rotation direction this moment, therefore the auto-lock spring has the speed reduction effect to the gear, makes operating personnel can walk downwards slowly then. The utility model discloses not only convenient to use, braking effect is good moreover, can effectively protect operating personnel's safety.

Detailed Description

To facilitate understanding by those skilled in the art, the structure of the present invention will now be described in further detail with reference to the following drawings:

1-3, A safety ladder for the interior of a tower barrel comprises a climbing ladder 1, the climbing ladder 1 comprises two support rods 2 fixedly connected to the inner side wall of the tower barrel, twelve pedals 3 are arranged between the support rods 2 at equal intervals, the middle of each pedal 3 is arranged in a concave shape, a fixing rod 4 with a end vertically and fixedly connected to the top of the tower barrel is arranged on the front side of the climbing ladder 1, a safety device 5 capable of moving up and down along the direction of the fixing rod 4 is mounted on the fixing rod 4, a through hole 7 used for matching with the fixing rod 4 is arranged on the safety device 5 in a penetrating mode, a rope 6 used for being connected to a human body is arranged on the outer side of the safety device 5, a plurality of tooth grooves 8 are sequentially arranged on the surface of the fixing rod 4 from top to bottom, a gear 9 is arranged in the safety device 5 in a position corresponding to the tooth grooves 8, a forward and reverse rotation motor 10 is connected to the right side of the gear 9, the forward and reverse rotation motor 10 is fixedly connected to the safety device 5, a switch button 11 corresponding to the forward and reverse rotation motor 10 is arranged on the outer portion of the safety device 5, a storage battery 12 and a spiral gear 13 used for supplying power to the forward and a spiral spring 15 are arranged in the safety device 5, and a self-locking spring 15 is connected to the.

The number of turns of the self-locking spring 14 is 15.

The outer side of the safety device 5 is provided with a charging port 16 corresponding to the storage battery 12 and the standby storage battery 13.

Before the utility model is used, only the rope 6 on the safety device 5 needs to be checked, which is more convenient and faster compared with the traditional check; when the climbing safety device is used, when an operator climbs, firstly, the rope 6 on the safety device 5 is connected to the operator, then the forward and reverse rotating motor 10 is started, the safety device 5 moves upwards through the matching of the internal gear 9 and the tooth groove 8 on the fixed rod 4, at the moment, the rotating direction of the gear 9 and the brake shaft 15 is opposite to the rotating direction of the self-locking spring 14, the self-locking spring 14 is in a loosening state, and the resistance generated to the rotation of the gear 9 is relatively small; when an operator slips accidentally, the safety device 5 is pulled down to cause the gear 9 to rotate reversely rapidly, the rotating directions of the gear 9 and the brake shaft 15 are the same as the rotating direction of the self-locking spring 14, the self-locking spring 14 can quickly hold the brake shaft 15 tightly, and large resistance is generated to the gear 9 instantaneously, so that the gear 9 stops rotating, and a timely braking effect is achieved; when an operator moves downwards, the forward and reverse rotating motor 10 rotates reversely to drive the gear 9, at the moment, the rotating direction of the gear 9 is the same as the rotating direction of the self-locking spring 14, and therefore the self-locking spring 14 has a speed reducing effect on the gear 9, and the operator can slowly move downwards.
