Detailed implementation mode

[0030] Next, the technical solutions of the present utility model will be described clearly and completely in conjunction with the embodiments. Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all the embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those skilled in the art without creative efforts belong to the scope of protection of the present utility model.

[0031] As shown in the attached Figure 1 to the attached Figure 6 As shown: A special pulley for the inclined surface of a dam includes a bevel bracket 1, universal wheels 11, a top plate 2 and a railing 21. The bevel bracket 1 is in a frame structure, and an inclined surface is formed from the left side to the bottom end surface of the frame structure. Then, four universal wheels 11 are distributed on the inclined surface of the frame structure. The top plate 2 is in a plate structure and is fixedly arranged on the upper surface of the bevel bracket 1. The railing 21 is fixedly arranged at the outer extension of the top of the top plate 2. At the same time, a mounting plate 3 is fixedly arranged at the middle end of the lower surface of the bevel bracket 1, and the mounting plate 3 is arranged opposite to the inclined surface end of the bevel bracket 1. Then, a cylindrical column 31 is rotatably arranged obliquely along the right side direction between the upper surface and the lower surface of the mounting plate 3. The lower end of the column 31 extends towards the slope surface of the dam, and the upper end extends towards the upper right. Finally, a drive wheel 33 is arranged at the lower end of the column 31, and the drive wheel 33 is in contact with the slope surface of the dam. Subsequently, a connecting rod 34 is fixedly arranged at the center of the drive wheel 33, and one end of the connecting rod 34 is rotatably connected to the outer end surface of the column 31.

[0032] In the above structure, through the settings of the bevel bracket 1, the top plate 2 and the railing 21, a maintenance platform suitable for the slope of the dam can be formed among them, which facilitates the user to carry out maintenance operations on the slope of the dam. In addition, the design of the column 31 and the drive wheel 33 enables the movement of the entire vehicle body, especially when the vehicle body moves horizontally on the slope of the dam, the drive wheel 33 can be used to drive the vehicle body to move.

[0033] Further, corresponding lifting lugs 12 are provided on the left side of the top of the bevel bracket 1. During use, the steel wire rope is used to pass through the lifting lug 12. For example, the steel wire rope can be towed through and hooked on the lifting lug 12 by manpower or a truck crane. After being hooked, the specific position of the vehicle body can be adjusted by moving the manpower or the truck crane. That is, when the manpower or the truck crane travels forward, the entire vehicle body can be towed by the steel wire rope, and the movement of the vehicle body at the dam slope can be realized during towing.

[0034] Further, a rectangular accommodation space 32 is communicated between the lower surface and the interior of the column 31. One end of the connecting rod 34 extends through to the inner wall surface of the accommodation space 32. Then, a first transmission wheel 35 is fixedly arranged at the extended end of the connecting rod 34. This design enables the connecting rod 34 to drive the first transmission wheel 35 to move when rotating. At the same time, a motor 36 is arranged above the interior of the accommodation space 32, and a second transmission wheel 37 is arranged along the transmission shaft of the motor 36. Subsequently, a transmission belt 38 is adaptively arranged on the outer end faces of the first transmission wheel 35 and the second transmission wheel 37. This design enables the motor 36 to drive the connecting rod 34 to rotate through the transmission belt 38 and the transmission wheel after rotation, and thus the motor 36 can provide power for the movement of the driving wheel 33.

[0035] As Figures 1 to 5 shown, in this embodiment, a connecting shaft is arranged at the upper end of the top of the column 31. The extending direction of the connecting shaft is consistent with the length direction of the column 31, and a bevel gear 311 is arranged at the connecting shaft. At the same time, a cylindrical vertical groove 42 is penetrated between the upper surface and the lower surface of the top plate 2. The vertical groove 42 is arranged vertically, and an adjusting rod 4 is rotatably arranged in the vertical groove 42. Both ends of the adjusting rod 4 extend above and below the top plate 2 respectively. Then, a bevel gear ring 411 is fixedly arranged at the lower end of the adjusting rod 4, and the outer end face of the bevel gear ring 411 is meshed with the bevel gear 311.

[0036] In the above structure, through the arrangement of the bevel gear 311, the adjusting rod 4 and the bevel gear ring 411, the user can drive the column 31 to move by rotating the adjusting rod 4, and the angle of the vertical rod can be adjusted during the movement, so that the driving wheel 33 in the vertical direction can be adjusted to the horizontal state, which is convenient for driving the vehicle body to move in the horizontal direction after adjustment.

[0037] Further, a limiting groove 43 is circumferentially formed on the inner wall surface of the vertical groove 42, and the included angle in the limiting groove 43 is specifically 90°. Then, a limiting block 44 is also slidably arranged in the limiting groove 43 in a matching manner, and one end of the limiting block 44 is connected to the outer end surface of the adjusting rod 4. This design enables the adjusting rod 4 to drive the limiting block 44 to slide in the limiting groove 43 when rotating, and the rotation direction of the upright column 31 can be limited by the 90° included angle in the limiting groove 43 after sliding. For example, when it is necessary to switch the direction of the upright column 31, only need to slide the limiting block 44 to the inner side of the limiting groove 43, so that after movement, the driving wheel 33 can be adjusted to the vertical or horizontal state.

[0038] Further, a rotating handle 41 is arranged at the upper end of the adjusting rod 4, and a button switch 45 is arranged on the upper surface of the rotating handle 41, and the button switch 45 is electrically connected to the motor 36. This design allows the user to control the opening or closing of the motor 36 through the button switch 45. At the same time, a storage battery is also arranged on the bevel bracket 1, and the storage battery is electrically connected to the button switch 45 and the motor 36. This design enables the storage battery to supply power to these electrical devices.

[0039] Further, a support rod 46 is horizontally and fixedly arranged on the outer wall upper end of the adjusting rod 4, and a lead screw 47 is threadedly arranged between the upper surface and the lower surface of the support rod 46. At the same time, a first opening 48 and a second opening 49 corresponding to the lead screw 47 are respectively arranged at intervals on the upper surface of the top plate 2, and internal threads adapted to the lead screw 47 are arranged in both the first opening 48 and the second opening 49. This design enables the lower end of the lead screw 47 to face the first opening 48 when the adjusting rod 4 drives the lead screw 47 to rotate clockwise, so that the lower end of the lead screw 47 can be screwed into the first opening 48 for limiting and locking. Similarly, when the adjusting rod 4 drives the lead screw 47 to rotate counterclockwise, the lower end of the lead screw 47 can face the second opening, so that the lower end of the lead screw 47 can be screwed into the second opening 49 for limiting and locking. When the adjusting rod 4 is locked, the upright column 31 and the driving wheel 33 can also be locked, effectively preventing the problem of deviation of the driving wheel 33.

[0040] Finally, it should be noted that the above embodiments are only specific implementation manners of the present application, used to illustrate the technical solutions of the present application, rather than limiting it. The protection scope of the present application is not limited thereto. Although the present application has been described in detail with reference to the foregoing embodiments, those of ordinary skill in the art should understand that any person skilled in the art within the technical scope disclosed by the present application can still modify the technical solutions recorded in the foregoing embodiments, or can easily think of changes, or perform equivalent replacements on some of the technical features; and these modifications, changes or replacements do not make the essence of the corresponding technical solutions deviate from the spirit and scope of the technical solutions of the embodiments of the present application, and should all be covered within the protection scope of the present application. Therefore, the protection scope of the present application should be based on the protection scope of the claims.
