Detailed Description

The following detailed description of the present invention is given for the purpose of better understanding technical solutions of the present invention by those skilled in the art, and the present description is only exemplary and explanatory and should not be construed as limiting the scope of the present invention in any way.

Referring to fig. 2 to 8, in a specific embodiment, a protective cage anti-entry safety device for a cooling tower comprises a protective cage 1 and a ladder stand 2, wherein a door mechanism 5 is arranged at the lower port of the protective cage 1; the door mechanism 5 comprises two door bodies 7 which are arranged on a cage hoop 6 and can be opened in a turnover way; a lock 9 is arranged between the two door bodies 7.

Wherein the lock 9 can be a padlock; the two door bodies 7 are respectively arranged at two sides of the cage hoop 6, and after being opened, the protective cage 1 is convenient for workers to enter and climb along the ladder stand 2.

As shown in fig. 5, in order to facilitate locking, further optimization is performed on the basis of the above embodiment: the door body 7 is provided with a lock hole 4 for hanging a lock 9.

As shown in fig. 6-7, further optimization is performed on the basis of the above-mentioned embodiments: the ladder stand 2 is arranged at the lower end of the protective cage 1 and can be lifted up and down; the door mechanism 5 is arranged at the lower end of the ladder stand 2. After the ladder stand 2 descends, the door mechanism 5 just leaves the lower port of the protective cage 1, and workers can enter the protective cage along the ladder stand 2; after the ladder stand 2 ascends, the door mechanism 5 just plugs up the lower port of the protective cage 1, so that non-workers are prevented from protecting the cage. In order to prevent the protective cage from being opened due to the fault of the crawling ladder 2, the protective cage can climb the cooling tower through the protective cage by opening two door bodies on the door mechanism 5.

Further optimization is carried out on the basis of the embodiment: slide rails 14 are arranged on two sides of the protective cage 1; the ladder 2 is arranged on a slide rail 14.

In order to enable the positioning and fixing of the lifting ladder 2 after the lifting ladder is lifted, the following optimization is further carried out on the basis of the embodiment: and a lock 9 is arranged between the cage hoop 6 and the lower port of the protective cage 1.

The utility model has the specific working principle that:

the door mechanism 5 is arranged at the lowest port of the upper tower ladder 2, and the door mechanism 5 consists of an outer-

layer cage hoop

6, 2 door bodies, 2 pin shafts and 1 padlock. Wherein the pin shaft can be a half-tooth bolt.

Half tooth bolt passes behind the rotatory hole in the location of the round pin axle fixed orifices on the cage hoop and the door body, fixes the round pin axle on the cage hoop through 2 nuts, supports simultaneously and spacing door body, and half tooth bolt has tooth's part to be used for screwing up 2 nuts, and the rotation of the door body is realized to the rotatory hole in the cooperation location of the part that does not have tooth, can realize the locking of the door body after the padlock in addition.

The 2 door bodies are arranged to prevent the single door body from being overlarge in size, so that potential safety hazards after the door body is unlocked by tower-climbing personnel are avoided, the material strength requirement of the single door body can be reduced, and the material cost is reduced; meanwhile, the cage hoop deformation caused by the device can be counteracted by the symmetrical arrangement.

4 door body fixing plates are welded on the cage hoop, pin shaft fixing holes are formed in the door body fixing plates, the welding distance between the two fixing plates is required to be larger than the width of a positioning supporting plate of the door body and the thickness of a nut, and a proper gap is reserved properly so as to rotate the door body, so that the door body is opened and closed;

the door body comprises outer protective frame, guard plate and location backup pad.

The outer protective frame is provided with a padlock hole so that a padlock can pass through the padlock holes of the 2 door bodies and then the door bodies are locked;

the number of the protection plates is determined according to the size of the cage hoop, so that the gap of the door body meets the safety standard;

the positioning support plate is provided with a positioning rotating hole, the pin shaft penetrates through the hole and then is fixed on the cage hoop, and a proper gap is reserved between the positioning bolt hole and the pin shaft so that the door body can be flexibly rotated.

After the padlock is opened, the door body freely droops under the action of gravity, and then, a maintainer can enter the protective cage to climb up the tower body for maintenance.
