In the following description, the description of the known structure and technology is omitted to avoid unnecessary confusion of the concept of the utility model.

[0028] First reference Figure 1 ,according to Figure 1 It can be seen that in the conventional technology, both sides of the leveling guide wheel 5 on the gas tank are hinged with vertically arranged brackets 51, and the bottom end of the bracket 51 is connected to the gas tank through a support 52. At the same time, in order to make the support 52 and the gas tank more firmly fixed, a plurality of screws can be welded at the position of the gas tank corresponding to the support 52, and then a plurality of threaded holes corresponding to the plurality of screws are opened on the support 52 (not shown in the figure), the screws on the gas tank are passed through the corresponding threaded holes, and nuts are threadedly connected to the screws, so that the support 52 and the gas tank can be firmly connected together through the cooperation of the nut and the screw.

[0029] When the leveling guide wheel 5 of the gas tank needs to be replaced, the utility model is first used to lift the wire rope upward, so that the leveling guide wheel 5 can be replaced without stopping the tank. Figure 2 ,according to Figure 2 It can be known that the utility model includes a base plate 3 on which a height adjustment mechanism 2 is vertically arranged, a first guide wheel 1 is arranged at the top of the height adjustment mechanism 2, and a second guide wheel 4 that can move up and down is arranged above the first guide wheel 1.

[0030] The height adjustment mechanism 2 of the present invention can be further referred to in the specific setting. Figure 2 ,according to Figure 2 It can be seen that the height adjustment mechanism 2 includes a threaded rod 21 vertically fixed on the bottom plate 3, a vertically arranged adjustment rod 23 is arranged above the threaded rod 21, and a cavity 231 for accommodating the threaded rod 21 is opened inside the adjustment rod 23; Figure 2 A connecting mechanism 22 for connecting the threaded rod 21 and the adjusting rod 23 is provided between the threaded rod 21 and the adjusting rod 23. The connecting mechanism 22 includes a first nut 221 fixedly connected to the bottom end of the adjusting rod 23. A second nut 223 is connected to the bottom of the first nut 221 through a bearing 222. The first nut 221 is fixedly connected to the outer ring of the bearing 222, and the second nut 223 is fixedly connected to the inner ring of the bearing 222 and is threadedly connected to the threaded rod 21.

[0031] The second guide wheel 4 in the utility model can be referred to in the specific setting Figure 3 ,according to Figure 3It can be seen that the two sides of the second guide wheel 4 are hinged to the first support plate 41 through the first rotating shaft 45, the top ends of the two first support plates 41 are fixedly connected to the same horizontal first connecting plate 42, and the upper part of the first connecting plate 42 is connected to an L-shaped plate 44 through a vertical telescopic rod 43. Specifically, the horizontal part of the L-shaped plate 44 is fixedly connected to the top end of the telescopic rod 43, and the vertical part of the L-shaped plate 44 is fixedly connected to the outer wall of the adjusting rod 23 of the height adjustment mechanism 2. At the same time, the telescopic rod 43 in the utility model can select a rod body with a telescopic function such as a spring rod commonly used in the prior art.

[0032] The first guide wheel 1 in the utility model can continue to refer to the specific setting Figure 3 ,according to Figure 3 It can be known that the two sides of the first guide wheel 1 are hinged to the second support plate 11 through the second rotating shaft 12 , and the bottom ends of the two first support plates 41 are fixedly connected to the top of the adjustment rod 23 .

[0033] The working principle of the gas tank guide wheel replacement device of this embodiment is as follows: when the utility model is used, the base plate 3 of the utility model is first placed on the support 52, and then the second nut 223 is rotated by a wrench, and another staff member holds the adjusting rod 23 to prevent the adjusting rod 23 from rotating. When the second nut 223 is rotated, the adjusting rod 23 can be moved upward along the threaded rod 21 until the wire rope is aligned between the first guide wheel 1 and the second guide wheel 4, and then the second guide wheel 4 is moved upward, and the utility model is moved until the wire rope and the first guide wheel 1 and the second guide wheel 4 are located in the same vertical plane; then the second nut 223 is continued to be rotated, and the position of the adjusting rod 23 is adjusted until the wire rope is in contact with the first guide wheel 1. At this time, the second guide wheel 4 is in contact with the wire rope at the same time under the action of the telescopic rod 43, and the wire rope is clamped by the first guide wheel 1 and the second guide wheel 4.

[0034] Then move the utility model and insert the base plate 3 between the two brackets 51. In order to make the utility model more firmly fixed on the support 52, a through hole (not shown in the figure) matching the screw can be opened at the position corresponding to the screw of the gas tank on the base plate 3. When the base plate 3 is placed on the support 52 and inserted between the two brackets 51, the screw is inserted into the through hole on the base plate 3 at the same time, and then the nut is screwed in, so that the base plate 3 and the support 52 are fixedly connected together.

[0035] Then continue to rotate the second nut 223 to move the first guide wheel 1 upward, thereby lifting the wire rope upward, making it convenient to replace the leveling guide wheel 5. At the same time, since the wire rope is clamped by the first guide wheel 1 and the second guide wheel 4, it can prevent the wire rope from detaching from the first guide wheel 1 during sliding.

[0036] At the same time, a support rod (not shown in the figure) is hinged on the bottom plate 3 in the utility model. When the utility model is not in use, the support rod is in a horizontal state and fits with the bottom plate 3. When the utility model is used, after adjusting the position of the first guide wheel 1, the support rod can be rotated so that one end of the support rod contacts the lower end surface of the bearing 222. At this time, a triangle is formed between the support rod, the bottom plate 3, and the threaded rod 21, which can provide support force for the bearing 222 and the components above the bearing 222.

[0037] At the same time, in order to prevent the steel wire rope from jumping up and down and pushing the second guide wheel 4 upward, when the utility model is used, after the positions of the first guide wheel 1 and the second guide wheel 4 are adjusted, the first support plate 41 and the second support plate 11 can be fixedly connected together through the second connecting plate (not shown in the figure), thereby temporarily fixing the first guide wheel 1 and the second guide wheel 4 as a whole, preventing the steel wire rope from jumping up and down and pushing the second guide wheel 4 upward.

[0038] When the second connecting plate is connected to the first supporting plate 41 and the second supporting plate 11 , they can be connected together by nuts and bolts that cooperate with each other.

[0039] In the above embodiment, the utility model provides a gas tank guide wheel replacement device, which can conveniently connect the utility model to the leveling guide wheel support, thereby facilitating the fixation of the utility model and facilitating the use of the utility model; at the same time, the height adjustment mechanism set in the utility model can conveniently adjust the height of the first guide wheel and the second guide wheel in the vertical direction until the first guide wheel contacts the wire rope and lifts the wire rope upward. At this time, the wire rope is separated from the leveling guide wheel, thereby facilitating the replacement of the leveling guide wheel.

[0040] The above-described embodiments are merely descriptions of preferred implementations of the present invention, and are not intended to limit the concept and scope of the present invention. Without departing from the design concept of the present invention, various modifications and improvements made by ordinary personnel in the field to the technical solution of the present invention should fall within the protection scope of the present invention, and the technical contents of the present invention for protection have been fully recorded in the claims.
