Description

Technical Field

[0001] The utility model relates to an elevator speed governor wire rope, in particular to a marine elevator speed governor wire rope protection device. Background Art

[0002] Since large ships are taller and have a larger space inside, they are usually equipped with a corresponding number of floors and floor heights based on the actual use scenarios of the ship. In order to facilitate the crew and passengers to travel between floors, a certain number of elevators will be installed on board to facilitate passengers and crew to go up and down the stairs. As ships travel in rivers, lakes, and seas, especially in the sea, they will be impacted by waves and shake to varying degrees. During the shaking process, the ship elevator and its various components will shake accordingly, especially the wire rope of the speed limiter, which will swing back and forth and come out of the groove, affecting the normal use of the elevator. Therefore, the existing technology has the problem that the wire rope of the speed limiter is prone to swinging and coming out of the groove. Utility Model Content

[0003] The purpose of the utility model is to provide a speed governor wire rope protection device for a marine elevator. The utility model has the characteristics of reducing the swing and groove-out phenomena of the speed governor wire rope.

DETAILED DESCRIPTION

[0014] The present invention is further described below in conjunction with the accompanying drawings and embodiments, but they are not intended to limit the present invention.

[0015] Embodiment 1. A marine elevator speed limiter wire rope protection device, comprising: Figure 1-4 As shown, it includes a connecting angle steel 1 fixed to the side wall of the shaft, an A bracket 2 is provided on the connecting angle steel 1, an anti-swing part 3 is provided on the A bracket 2, and the speed limiter wire rope passes through the anti-swing part 3; the anti-swing part 3 includes a swing part body 301 of a C-shaped structure, and an upper telescopic roller group 302 and a lower telescopic roller group 303 are respectively provided at the upper and lower ends of the swing part body 301, and the upper telescopic roller group 302 and the lower telescopic roller group 303 are respectively located on both sides of the wire rope.

[0016] The upper telescopic roller group 302 and the lower telescopic roller group 303 both include a telescopic rod 304 fixed on the swing member body 301, the telescopic rod 304 is provided with a spring 305, the end of the telescopic rod 304 is provided with a B bracket 306, the B bracket 306 is provided with a connecting shaft 307, and the connecting shaft 307 is provided with a roller 308.

[0017] The diameter of the middle portion of the roller 308 is smaller than the diameters of the two ends.

[0018] The B bracket 306 includes a first bracket 361 and a second bracket 362 that slide against each other; the first bracket 361 is provided with a long waist-shaped hole 363, and the second bracket 362 is provided with two sliding studs 364 that match the long waist-shaped hole 363, and the sliding studs 364 are provided with fastening nuts 365.

[0019] The middle diameter of the roller is smaller than the diameters at both ends, so that the roller can limit the wire rope and prevent large-scale forward and backward shaking when it occurs.

[0020] The B bracket is composed of a first bracket and a second bracket that are slidably connected. The bracket with adjusted length is fastened by a fastening nut and a sliding stud, so that it can be flexibly adjusted according to the actual installation distance to meet the actual installation requirements.

[0021] B. Bracket adjustment process: Extend the first bracket and the second bracket outward, then tighten the fastening nut to the sliding stud to achieve the final fixation of the first bracket and the second bracket. Two sliding studs are provided to prevent the first and second brackets from rotating.

[0022] The working process of the upper telescopic roller group: in the initial state, the telescopic rod is in an extended state under the action of the spring force, and is located on one side of the central wire rope. The wire rope is in contact with the middle of the roller. When the wire rope moves up and down, it will cause the roller to roll accordingly; when left and right shaking occurs, the spring will be compressed to reduce the impact of the left and right shaking of the ship on the wire rope.

[0023] The installation process of the utility model is as follows: first, the connecting angle steel, the A bracket and the anti-swing part are assembled and fixed together on site (they can be fixed by welding, the connecting angle steel and the anti-swing part are respectively located at the two ends of the A bracket, and then the upper telescopic roller group and the lower telescopic roller group are fixed to the upper and lower ends of the anti-swing part), and then the protective device is fixed to the side wall surface of the shaft corresponding to the speed limiter by bolts, and then the speed limiter wire rope passes through the anti-swing part, so that the anti-swing part can protect the speed limiter wire rope, and when shaking forward, backward, left and right occurs, the upper telescopic roller group and the lower telescopic roller group are protected, effectively preventing the wire rope from swinging too much and preventing it from getting out of the groove.

[0024] Embodiment 2. The difference between this embodiment and embodiment 1 is that an adjusting spring sleeved on the connecting shaft is provided between the front and rear sides of the roller and the B bracket, and limit plates are provided on both sides of the middle part of the roller, and a cavity corresponding to the steel wire rope is provided between the two limit plates. The steel wire rope is located between the two limit plates. When it swings back and forth, it will drive the roller to move back and forth, compress the adjusting spring at the corresponding position, reduce the amplitude of the forward and backward swing, and play an effective protective role.
