Detailed Description

The present application is described in further detail below with reference to figures 1-4.

The embodiment of the application discloses cooling tower with cat ladder subassembly. Referring to fig. 1, a cooling tower with cat ladder subassembly, including the tower body 1, locate the fan 2 of tower body 1 upper end, locate interior maintenance platform 3 in the tower body 1, locate the last maintenance platform 4 of tower body 1 upper end, locate the cooling module in the tower body 1. The position of the tower body 1 corresponding to the cooling module is provided with a ventilation groove 5.

In order to maintain the cooling tower conveniently, a first maintenance opening 6 leading to the inner maintenance platform 3 is formed in the side wall of the tower body 1, and a second maintenance opening 7 leading to the upper maintenance platform 4 is formed in the upper end of the tower body 1. And the first maintenance opening 6 and the second maintenance opening 7 are both provided with maintenance doors 8. The tower 1 is provided with a first ladder 9 for an operator to enter the first service opening 6 from the ground. Inside the tower 1 there is a second ladder stand 10 for an operator to enter the second maintenance opening 7 from the internal maintenance platform 3. The first ladder stand 9 and the second ladder stand 10 are both arranged obliquely. The tower 1 is provided with a third ladder 11 for an operator to climb directly from the ground to the upper service platform 4.

When using, the first cat ladder 9 of accessible climbs in interior maintenance platform 3, then walks to second cat ladder 10 department again, climbs to last maintenance platform 4 through second cat ladder 10 on, and the segmentation climbing is safe more easily. Of course, a skilled climber may also climb directly onto the upper service platform 4 using the third ladder 11. The cooling tower can be adapted to various maintenance persons.

In particular, the first ladder 9 comprises two fixed bars 12, a ladder unit 13 and reinforcing bars 14. Two fixed rods 12 are arranged along the vertical direction and are respectively positioned at two sides of the first maintenance opening 6. The fixing rod 12 is fixedly arranged on the outer wall of the cooling tower. The ladder unit 13 is located between two fixing bars 12. Both sides of the upper end of the ladder climbing unit 13 are in threaded connection with adjusting screws 15, and the adjusting screws 15 penetrate through the corresponding fixing rods 12 and are rotatably connected to the fixing rods 12. One end of the adjusting screw rod 15 is connected with an adjusting nut 16 in a threaded manner. The ladder unit 13 is rotatably coupled to the fixing rod 12 by an adjusting screw 15. The angle of the ladder climbing unit 13 relative to the cooling tower can be adjusted according to actual requirements, so that the climbing requirements of different maintainers are met. At the same time, the resistance when the ladder unit 13 is rotated with respect to the fixing rod 12 can be adjusted by screwing the adjusting nut 16, so that the ladder unit 13 can be rotated with respect to the fixing rod 12 and also can be stabilized at an artificially adjusted angle with respect to the fixing rod 12.

A reinforcing rod 14 is arranged between each fixing rod 12 and the ladder climbing unit 13, and a plurality of reinforcing rods 14 are arranged along the length direction of the fixing rods 12. The holding tank 17 is opened on one side of the fixed rod 12 departing from the tower body 1. One end of the reinforcing rod 14 is embedded in the accommodating groove 17 and is slidably connected to the accommodating groove 17, and the other end of the reinforcing rod 14 is rotatably connected to the side wall of the ladder climbing unit 13. The lateral wall of accommodation groove 17 both sides has seted up spout 18, and sliding connection has slider 19 in the spout 18. The reinforcing rod 14 is embedded in the accommodating groove 17, and both sides of one end are provided with a rotating shaft 20, one rotating shaft 20 corresponds to one sliding block 19, and the rotating shaft 20 is rotatably connected in the corresponding sliding block 19. Thereby pivotally connecting the reinforcing bar 14 to the fixing bar 12 and slidably connecting the reinforcing bar 14.

The reinforcing rods 14 serve to reinforce the structural strength between the ladder unit 13 and the fixed rod 12 when the ladder unit 13 is deployed, making the first ladder 9 more stable. When the ladder stand unit 13 needs to be stored, the ladder stand unit 13 is pushed inwards, the reinforcing rod 14 is embedded into the accommodating groove 17 in a rotating mode relative to the ladder stand unit 13, the sliding block 19 slides in the sliding groove 18 to achieve motion compensation, and the storage of the first ladder stand 9 is completed.

In order to make the ladder unit 13 more stable in use, a locking element for locking is provided between the fixing rod 12 and the reinforcement rod 14. The locking member comprises a magnet 21. Magnet 21 is connected in the spout 18 that slides, is equipped with mounting bolt 22 on magnet 21, and mounting bolt 22 passes magnet 21 and mounting nut 23 is equipped with one end of mounting bolt 22. By tightening the mounting nut 23, the mounting bolt 22 and the mounting nut 23 clamp the fixing rod 12, and the magnet 21 is fixed to the fixing rod 12. When the first ladder 9 is unfolded until the first ladder unit 13 is inclined to the utmost, the magnet 21 attracts the slider 19, so that the first ladder unit 13 is more stably positioned at the adjusted angle. Meanwhile, the outward expansion limit position of the ladder climbing unit 13 can be adjusted by adjusting the position of the magnet 21 relative to the fixed rod 12, and the operation is convenient.

In order to facilitate the storage of the first ladder 9, a spring 24 is provided between the slider 19 and the end of the runner 18 remote from the magnet 21. When the slider 19 is attracted by the magnet 21, i.e. the ladder unit 13 is in a state of extreme outward deployment, the spring 24 is in a stretched state, tending to pull the slider 19 away from the magnet 21. When the first ladder stand 9 needs to be stored, the ladder stand unit 13 is pushed inwards, and when the slide block 19 leaves the magnet 21, the slide block 19 is more quickly separated from the magnet 21 under the action of the spring 24, so that the resistance which needs to be overcome when the ladder stand unit 13 rotates inwards is reduced.

The above embodiments are preferred embodiments of the present application, and the protection scope of the present application is not limited by the above embodiments, so: all equivalent changes made according to the structure, shape and principle of the present application shall be covered by the protection scope of the present application.
