DETAILED DESCRIPTION

[0018] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0019] When implementing: Figure 1-4 As shown, a hoist pulley guide rail structure capable of reducing shaking comprises: a guide rail body 1, a traveling mechanism 101 is arranged on the surface of the guide rail body 1, and an electric hoist 2 is arranged at the bottom of the traveling mechanism 101; an auxiliary mechanism 3, the auxiliary mechanism 3 comprises a mounting frame 31 fixedly connected to the surface of the traveling mechanism 101, and a limiting component 32 is fixedly connected to the lower end of the mounting frame 31; wherein, the limiting component 32 comprises a connecting plate 321 fixedly connected to the surface of the mounting frame 31, a through slot 325 is provided on the top of the connecting plate 321, and a chain of the electric hoist 2 passes through the through slot 325.

[0020] like Figure 1 , Figure 2 , Figure 3 and Figure 4 As shown, two symmetrically distributed mounting plates 322 are fixedly connected to the top of the connecting plate 321, two symmetrically distributed slide plates 324 are arranged between the two mounting plates 322, and the opposite sides of the two slide plates 324 are rotatably connected with guide wheels 328, and the surface of the guide wheels 328 is in contact with the chain of the electric hoist 2.

[0021] The surface of the slide plate 324 is fixedly connected with two symmetrically distributed connecting shafts 329, the other end of the connecting shaft 329 passes through the adjacent mounting plate 322, the surface of the mounting plate 322 is fixedly connected with two symmetrically distributed mounting blocks 323, and a spring 3210 is fixedly connected between the connecting shaft 329 and the adjacent mounting block 323;

[0022] The swing range of the chain is limited under the action of the through slot 325, and at the same time, the slide plate 324 can drive the two guide wheels 328 to be in close contact with the chain of the electric hoist 2 under the action of the spring 3210, thereby ensuring that their position will not swing too much.

[0023] like Figure 1 , Figure 2 , Figure 3 and Figure 4As shown, the inner wall of the connecting plate 321 is slidably connected with two slide bars 3211, the opposite ends of the two slide bars 3211 are penetrated into the interior of the through groove 325 and fixedly connected with a trigger block 3214, the surface of the slide bar 3211 is fixedly connected with two symmetrically distributed guide plates 3212, the guide plates 3212 are slidably connected with the inner wall of the connecting plate 321, the top of the connecting plate 321 is rotatably connected with two symmetrically distributed gears 326, the top of the slide bar 3211 is fixedly connected with a second rack 3213, the second rack 3213 is meshedly connected with the adjacent gear 326, the bottom of the slide plate 324 is fixedly connected with a first rack 327, the first rack 327 is transmission-connected with the adjacent gear 326;

[0024] When the chain shakes, it will slide along the inner wall of the through groove 325, reducing the range of the shaking and limiting the direction of the shaking. When the chain shakes, it can squeeze the trigger block 3214 to push the slide bar 3211 to move. In this process, it can drive the second rack 3213 to move synchronously, and then drive the adjacent first rack 327 to move in the opposite direction through the gear 326, so as to achieve the effect of pushing the chain in the opposite direction of the shaking, so as to achieve the function of reducing the shaking.

[0025] When the utility model is in use, the swinging range of the chain is limited under the action of the through groove 325, and at the same time, under the action of the spring 3210, the slide plate 324 can drive the two guide wheels 328 to be close to the chain of the electric hoist 2, thereby ensuring that their positions will not produce too much swing. When swinging occurs, the chain will slide along the inner wall of the through groove 325, reducing the range of the swing and limiting the direction of the swing. When the chain swings, the trigger block 3214 can be squeezed to push the slide bar 3211 to move.
