Abstract
The utility model relates to a sealing structure of the top end of a pole tower. The sealing structure of the top end of the pole tower comprises a pole tower body, a lower cover plate is arranged inside the top end of the pole tower body, a fixing nut is arranged on the upper side of the lower cover plate, an upper cover plate is arranged on the end surface of the top end of the pole tower boy, and the upper cover plate is fixed through a fixing bolt matched with the fixing nut. The sealing structure of the top end of the pole tower improves the bolt of a traditional connection structure into the inner portion of the pole tower body, thus the fixing bolt cannot conflict with the component outside the pole tower, packaging is further enabled to be more tight, the water leakage from the clearance between the upper cover plate and the top end surface of the pole tower body is avoided, and therefore the pole tower body is protected, and the strength and the service life of the pole tower body are improved.
Description
Technical field
The utility model belongs to the steel tower technical field, relate in particular to that a kind of hermetically-sealed construction that has solved existing shaft tower top exists with shaft tower on the hermetically-sealed construction on shaft tower top of other component collisions, encapsulation imprecision, the problem such as leak.
Background technology
Along with the input increasing of China to infrastructure in recent years, increasing shaft tower is set up.The tower body of shaft tower all adopts tubular structure, therefore the top of tower body all will seal, as shown in Figure 1, the hermetically-sealed construction on existing shaft tower top comprises shaft tower body 101, the top of shaft tower body 101 is provided with flange 102, on flange 102, by bolt 104 securing cover plates 103, bolt 104 is arranged on the outside of shaft tower body 101; Be arranged on like this outside of shaft tower body 101 due to bolt 104, so when practice of construction, bolt 104 tend to shaft tower body 101 on other component collisions, cause the bolt 104 can not holddown plate 103, cause rainwater from the gap of cover plate 103 and flange 102 to the interior infiltration of shaft tower body 101, the rainwater of infiltration can corrode shaft tower body 101, for a long time corrosion causes the strength decreased of shaft tower body 101, have a strong impact on the intensity of shaft tower body 101, existed very large safety.
Summary of the invention
The purpose of this utility model is in order to overcome the deficiencies in the prior art, and provide a kind of not can with shaft tower on the hermetically-sealed construction on other component collisions, tight, the watertight shaft tower of encapsulation top.
The purpose of this utility model is achieved in that the hermetically-sealed construction on a kind of shaft tower top, comprise the shaft tower body, the inside on described shaft tower body top is provided with lower cover, the upside of lower cover is provided with hold-down nut, be provided with upper cover plate on the end face of shaft tower body top, upper cover plate is fixed by the set bolt that matches with hold-down nut.
Described lower cover is fixed on inside, shaft tower body top and vertical with the axis of shaft tower body by the mode of welding.
The diameter of described upper cover plate is greater than or equal to the diameter of shaft tower body.
Be provided with waterproof pad between described upper cover plate and shaft tower body top end face.
The utlity model has following positive effect: the utility model is improved to the inside of shaft tower body with the bolt of traditional syndeton from the outside of shaft tower body, like this set bolt just not can with the component collisions of shaft tower body exterior, and then make encapsulation more tight; The diameter of upper cover plate is greater than or equal to the diameter of shaft tower body, avoided like this between upper cover plate and shaft tower body top end face to shaft tower body infiltration, and then protected the shaft tower body, improved intensity and the application life of shaft tower body; Between upper cover plate and shaft tower body top end face, waterproof pad is set, makes like this encapsulation tighter.

The specific embodiment
Below in conjunction with accompanying drawing, the utility model is described further:
Embodiment 1
As shown in Figure 2, the hermetically-sealed construction on a kind of shaft tower top, comprise shaft tower body 201, the inside on described shaft tower body 201 tops is provided with lower cover 202, the upside of lower cover 202 is provided with hold-down nut 203, be provided with upper cover plate 204 on shaft tower body 201 top end faces, upper cover plate 204 is fixing by the set bolt 205 that matches with hold-down nut 203.
The utility model is improved to the inside of shaft tower body with the bolt of traditional syndeton from the outside of shaft tower body, like this set bolt just not can with the component collisions of shaft tower body exterior, and then make encapsulation more tight; The diameter of upper cover plate is greater than or equal to the diameter of shaft tower body, avoided like this between upper cover plate and shaft tower body top end face to shaft tower body infiltration, and then protected the shaft tower body, improved intensity and the application life of shaft tower body.
Embodiment 2
As shown in Figure 2, the hermetically-sealed construction on a kind of shaft tower top, comprise shaft tower body 201, the inside on described shaft tower body 201 tops is provided with lower cover 202, the upside of lower cover 202 is provided with hold-down nut 203, be provided with upper cover plate 204 on shaft tower body 201 top end faces, upper cover plate 204 is fixing by the set bolt 205 that matches with hold-down nut 203.
It is inner and vertical with the axis of shaft tower body 201 that the mode of described lower cover 202 by welding is fixed on shaft tower body 201 tops.
The diameter of described upper cover plate 204 is greater than or equal to the diameter of shaft tower body 201.
Be provided with waterproof pad between described upper cover plate 204 and shaft tower body 201 top end faces.
The utility model is improved to the inside of shaft tower body with the bolt of traditional syndeton from the outside of shaft tower body, like this set bolt just not can with the component collisions of shaft tower body exterior, and then make encapsulation more tight; The diameter of upper cover plate is greater than or equal to the diameter of shaft tower body, avoided like this between upper cover plate and shaft tower body top end face to shaft tower body infiltration, and then protected the shaft tower body, improved intensity and the application life of shaft tower body; Between upper cover plate and shaft tower body top end face, waterproof pad is set, makes like this encapsulation tighter.
