Embodiment 1

[0038] Embodiment 1 of the present invention relates to a rotating floating ladder roller device for a storage tank with a floating roof.

[0039] like Figure 1 to Figure 3 As shown, the rotating floating ladder roller device of the floating roof storage tank includes a roller mechanism 3 , a floating ladder supporting mechanism 6 and a rotating floating ladder 1 . A pedestrian step board 2 is provided on the rotating floating ladder 1 .

[0040] The roller mechanism 3 includes a roller shaft 4 and two rollers mounted on the end of the roller shaft 4, such as the roller 3.1.

[0041] During rotating floating ladder 1 operation, roller shaft 4 does not rotate, and two rollers 3.1 move back and forth along following track 7.

[0042] Wherein, the roller mechanism 3 is located above the track 7, and the two rollers 3.1 are installed on one of the tracks 7 respectively.

[0043] The floating ladder supporting mechanism 6 is located above the roller mechanism 3 and is connected...

Embodiment 2

[0057] Embodiment 2 of the present invention also relates to a floating-roof storage tank rotating ladder roller device. Except for the following technical features of the floating ladder roller device in Embodiment 2, which are different from the above-mentioned Embodiment 1, other technical features can be referred to Example 1 above.

[0058] like Figures 1 to 3 As shown, the explosion-proof wrapping layer 3.2 in this embodiment 2 is composed of multiple arc-shaped wrapping layers.

[0059] This design method can solve the following technical problems:

[0060] If a whole explosion-proof coating layer 3.2 is fixed on the roller 3.1, the explosion-proof coating layer 3.2 bears the weight of the entire rotating floating ladder 1. Because the material of the explosion-proof coating layer is highly brittle, it is prone to fracture during rolling.

[0061] This embodiment 2 solves the problem of fracture and shedding of the surface explosion-proof wrapping layer 3.2 through t...

Embodiment 3

[0074] This embodiment 3 relates to an installation method of the floating roof storage tank rotating ladder roller device as in the above embodiment 1 or the above embodiment 2, which adopts the following technical scheme:

[0075] The installation method of the rotating floating ladder roller device of the floating roof storage tank includes the following steps:

[0076] s1. Place the roller mechanism 3 above the track 7, and install the two rollers 3.1 on one of the tracks 7 respectively;

[0077] s2. The floating ladder support mechanism 6 is fixedly installed on the roller mechanism 3;

[0078] s3. Install the rotating floating ladder 1 on the supporting mechanism 6 of the floating ladder, wherein the shaft sleeve 5.1 of the floating ladder is sleeved on the supporting plate shaft 6.2.

Abstract

The invention discloses a rotating floating ladder roller device for a storage tank with a floating roof. The device includes a roller mechanism, a floating ladder support mechanism and a rotating floating ladder; the roller mechanism includes a roller shaft and two rollers installed at the end of the roller shaft; the floating ladder support mechanism includes a support rod, a supporting plate and a supporting plate shaft; The lower end of the support rod is fixedly installed on the roller shaft, and the upper end of the support rod is fixedly installed on the bottom of the supporting plate; the supporting plate shaft is vertically arranged in the middle of the upper surface of the supporting plate; There is a floating ladder shaft sleeve sleeved on the supporting plate shaft. The invention eliminates the torque between the track and the floating ladder, reduces the abrasion of the anti-explosion wrapping layer on the surface of the roller caused by the deflection of the track, and can also prevent the floating ladder from derailing.

Description

technical field [0001] The invention belongs to the technical field of oil and gas storage and transportation, and relates to a rotating floating ladder roller device for a storage tank with a floating roof. Background technique [0002] At present, a rotating floating ladder is provided between the floating roof and the tank wall of the storage tank to facilitate the passage of personnel and equipment during inspection and maintenance of the floating roof storage tank. Usually, there are railings and handrails on both sides of the rotating floating ladder. The top of the rotating floating ladder is fixed on the operating platform at the top of the tank wall, and the bottom of the rotating floating ladder is equipped with rollers, which are placed above the track on the surface of the floating roof just below the rotating floating ladder. [0003] When the floating roof is raised and lowered, the rotating floating ladder runs along the track, and the rotating floating ladde...
