Description

Technical Field

[0001] The utility model relates to a large wheel platform disassembly tool and belongs to the field of automobile quick maintenance. Background Art

[0002] A tire is a ring-shaped elastic rubber product installed on the wheel of a vehicle or machine. It is usually made of wear-resistant rubber material and installed on a metal rim. The tire consists of four main parts: the cord layer, the bead, the buffer layer, and the tread. The performance of the tire basically depends on these four parts.

[0003] The outer diameter of tires for small vehicles is generally between 35.56CM and 50.8CM, the outer diameter of medium-sized tires is generally 60CM, and the outer diameter of large tires is 100CM. The wheels and outer tires of large tires generally weigh 25-40 kilograms.

[0004] The main steps of removing a large tire from a truck are: using a pneumatic cannon to remove all the nuts or bolts on the tire, and using left and right hands to shake the tire to remove it from the car's drive shaft. Since the tire weighs at least 25 kilograms, and some even weigh 40 kilograms, it cannot be lifted by one person alone. On the contrary, when reinstalling the tire on the car's drive wheel, manpower is needed to lift it again and realign it with the bolt installation position. Fine-tuning is required in this process. It is already quite strenuous for one person to support the tire, and fine-tuning is even more difficult.

[0005] Therefore, the utility model provides a disassembly tool capable of adjusting the height during the disassembly of a large vehicle tire. Utility Model Content

[0006] In view of this, the purpose of the utility model is to provide a disassembly tool capable of adjusting the height during the disassembly of a large vehicle tire.

[0007] The utility model is achieved in this way:

[0008] A large wheel platform disassembly tool comprises an arc-shaped bracket for accommodating a large tire;

[0009] A hydraulic cylinder, a moving wheel and a bottom plate, wherein a plurality of moving wheels are fixed at the four corners of the bottom surface of the bottom plate, a hydraulic cylinder is vertically installed at one end of the bottom plate, and an output end at the top of the hydraulic cylinder is mechanically fixed to the bottom end of the arc-shaped bracket;

[0010] The hydraulic cylinder drives the arc-shaped bracket to move up and down in the vertical direction.

[0011] As a further improvement, the arc-shaped bracket comprises a main body, and the main body is composed of two arc-shaped side plates vertically fixed on the arc edge of the arc-shaped bottom plate;

[0012] The accommodation cavity is the space between the two curved side panels to accommodate large tires.

[0013] As a further improvement, the free end edge of the arc-shaped side plate curls inwardly into a semicircular portion.

[0014] As a further improvement, both ends of the arc-shaped bracket are covered with silicone sleeves.

[0015] As a further improvement, the arc-shaped bracket is made of stainless steel.

[0016] As a further improvement, the diameter of the circle where the arc-shaped bottom plate of the arc-shaped bracket is located is larger than the diameter of the large tire.

[0017] As a further improvement, a plurality of rollers are arranged inside the accommodating cavity of the arc-shaped bracket, and the rollers include a plurality of fixed shafts installed between two arc-shaped side plates, and a hollow sleeve is sleeved on the fixed shaft.

[0018] As a further improvement, the cross-sectional diameter of the hollow sleeve is larger than the diameter of the fixed shaft.

[0019] As a further improvement, a buffer bracket is vertically fixed to the other horizontal end of the bottom plate through a bracket.

[0020] As a further improvement, one end of the buffer bracket is movably tangent to the arc bracket, and the height h between the other end and the bottom surface is 3-7 cm.

[0021] The beneficial effects of the utility model are:

[0033] Reference Figure 1-Figure 5 As shown, this embodiment provides a specific implementation method for a large wheel platform disassembly tool, including an arc-shaped bracket 10 for accommodating a large tire;

[0034] A hydraulic cylinder 20, a moving wheel 50 and a bottom plate 60, wherein a plurality of moving wheels 50 are fixed at the four corners of the bottom surface of the bottom plate 60, a hydraulic cylinder 20 is vertically installed at one end of the bottom plate 60, and an output end at the top of the hydraulic cylinder 20 is mechanically fixed to the bottom end of the arc-shaped bracket 10;

[0035] The hydraulic cylinder 20 drives the arc-shaped bracket 10 to move up and down in the vertical direction.

[0036] The hydraulic cylinder 20 described here is a foot-operated hydraulic cylinder, which is commonly used in beauty beds and medical beds. The height of the arc bracket 10 can be adjusted by stepping on it. When stepping down, it can be raised by 5cm at a time, with four gears in total. The foot pedal is lifted by the toes, and the foot pad can be moved back to the bottom.

[0037] In one specific embodiment, a half-moon-shaped push opening 40 is formed on the edge of the bottom plate 60 of the arc-shaped bracket 10 .

[0038] When the utility model removes a tire, a plurality of moving wheels 50 are installed at the bottom of the bottom plate 60, and the entire tooling can be moved horizontally to the bottom of the tire of the truck that needs to be removed. The arc bracket 10 is adjusted to move upward by the hydraulic cylinder 20 until the arc bracket 10 fits with the bottom surface of the truck tire. After the tire is removed, the hydraulic cylinder 20 is used to lower the arc bracket 10 in the reverse direction, and there is no need to lift it manually, which is extremely convenient to operate.

[0039] On the contrary, when installing the tire, place the large tire on the arc bracket 10 to move the entire tooling horizontally to the side of the drive shaft of the truck where it needs to be installed, and adjust the arc bracket 10 to move upward through the hydraulic cylinder 20 until the large tire of the arc bracket 10 is on the same horizontal line as the drive shaft, align the foot with the push opening 40, and push the bracket forward so that the large tire fits perfectly with the drive shaft. It is more labor-saving to push with the foot.

[0040] The arc-shaped bracket 10 comprises a main body 101, and the main body 101 is composed of two arc-shaped side plates 111 vertically fixed on the arc edge of the arc-shaped bottom plate 112;

[0041] The accommodating chamber 102, the space between the two arc-shaped side plates 111, is used to place a large tire.

[0042] Furthermore, the free end edge of the arc-shaped side panel curls inwardly into a semicircular portion 705, and silicone sleeves 704 are provided at both ends of the arc-shaped bracket 10. The arc-shaped bracket 10 is made of stainless steel material with high hardness. If the thickness is relatively thin, it is easy to cut human hands during use. The inward curling design and silicone sleeve wrapping are adopted to reduce the frequency of safety accidents.

[0043] Furthermore, the diameter of the circle where the arc-shaped bottom plate 112 of the arc-shaped bracket 10 is located is larger than the diameter of the large tire, so that the arc-shaped bracket has an arc and can place the large tire without allowing the large tire to be embedded inside.

[0044] Furthermore, a plurality of rollers are arranged inside the accommodating cavity 102 of the arc-shaped bracket 10. The rollers include a plurality of fixed shafts 702 installed between two arc-shaped side plates 111, and a hollow sleeve 701 is sleeved on the fixed shaft 702, so that the large tire can be placed on the arc-shaped bracket and rotated left and right to achieve fine adjustment, so that the mounting hole on the large tire and the mounting hole of the vehicle drive shaft can maintain the same position.

[0045] Furthermore, the cross-sectional diameter of the hollow sleeve 701 is larger than the diameter of the fixed shaft 702. The hollow sleeve 701 can rotate on the fixed shaft 702. When fine-tuning, moving left and right is more labor-saving, making the adjustment easier.

[0046] A buffer bracket 70 is vertically fixed to the other horizontal end of the bottom plate 60 through a bracket 30. The buffer bracket is a smooth arc-shaped bracket, which can be used for buffering to facilitate large tires to roll from the arc-shaped bracket 10 to the ground.

[0047] Further, one end of the buffer bracket 70 is tangent to the arc bracket 10, that is, one end of the buffer bracket 70 is in movably contact with the arc bracket 10, and the end is inclined downward. When the arc bracket 10 drops to the lowest point, it is completely tangent to the buffer bracket 70, and the connection is stable, which is convenient for the rolling of large tires.

[0048] Furthermore, the height h of the other end of the buffer bracket 70 from the ground is 3-7 cm. During the process of moving the tooling, no motion interference problem will occur. It is only 3-7 cm from the ground. During the process of reassembling the large tire, the large tire can also be rolled up directly and rolled along the buffer bracket 70 toward the arc bracket 10.

[0049] The above description is only the preferred implementation of the utility model, and is not intended to limit the utility model. For those skilled in the art, the utility model can have various modifications and changes. Any modification, equivalent replacement, improvement, etc. made within the spirit and principle of the utility model shall be included in the protection scope of the utility model.
