Embodiment 1
[0040] Embodiment 1 of the present invention relates to a rotating floating ladder roller device for a storage tank with a floating roof.
[0041] Such as 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 .
[0042] 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.
[0043] 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.
[0044] 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.
[0045] The floating ladder supporting mechanism 6 is located above the roller mechanism 3 and is connec...
Embodiment 2
[0059] 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.
[0060] Such as 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.
[0061] This design method can solve the following technical problems:
[0062] 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.
[0063] This embodiment 2 solves the problem of fracture and shedding of the surface explosion-proof wrapping layer 3.2 throug...
Embodiment 3
[0076] Such as Figure 4 As shown, this embodiment 3 has described a kind of installation method of the rotating floating ladder roller device in the floating roof storage tank as in the above embodiment 1 or the above embodiment 2, which adopts the following technical scheme:
[0077] The installation method of the rotating floating ladder roller device of the floating roof storage tank includes the following steps:
[0078] s1. Place the roller mechanism 3 above the track 7, and install the two rollers 3.1 on one of the tracks 7 respectively;
[0079] s2. The floating ladder support mechanism 6 is fixedly installed on the roller mechanism 3;
[0080] 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 mounting method of a rotating floating ladder roller device of a floating roof storage tank. The device adopted in the mounting method comprises a roller mechanism, a floating ladder support mechanism and a rotating floating ladder. The roller mechanism comprises a roller wheel shaft and two roller wheels arranged at the end portions of the roller wheel shaft. The floating ladder support mechanism comprises a support rod, a support plate and a support plate shaft. The lower end of the support rod is fixedly mounted on the roller wheel shaft. The upper end of the support rod is fixedly mounted at the bottom of the support plate. The support plate shaft is vertically arranged in the middle position of the upper surface of the support plate. The rotating floating ladder comprises a floating ladder base. A floating ladder shaft sleeve arranged on the support plate shaft in a sleeving manner is arranged on the floating ladder base. The mounting method comprises thesteps that the mounting of the roller mechanism, the floating ladder support mechanism and the rotating floating ladder is sequentially achieved. By the adoption of the mounting method of the rotating floating ladder roller device of the floating roof storage tank, the torque between a track and the floating ladder is eliminated, the abrasion of anti-explosion wrapping layers on the surfaces of the roller wheels caused by the deflection of the track is reduced, and the out-of-the-track of the floating ladder can also be prevented.
Description
technical field [0001] The invention belongs to the technical field of oil and gas storage and transportation, and relates to an installation method of a rotating floating ladder roller device for a floating roof storage tank. 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 rota...
