Description

TECHNICAL FIELD

[0001] The utility model relates to heavy -duty truck tire renovation technical device field, and mainly relates to heavy -duty truck tire renovation device, especially a heavy -duty truck tire renovation and press together device. BACKGROUND

[0002] The heavy -duty truck of mine is usually worse because its working environment, and the road surface of working site is mostly gravel, and various sharp substances such as iron nails, iron sheet etc. can cause great harm to the tire, so the tire of heavy -duty truck is generally damaged. Thus, the easily damaged tire of heavy -duty truck is damaged because its volume is relatively large and material is much, thus, if the old tire of heavy -duty truck can be used as the condition of renovation, it will be generally used for renovation, but because the tire of heavy -duty truck is relatively large, in the process of renovating heavy -duty truck, it is not only large in volume, but also heavy, and general workers are difficult to move. Thus, in the process of renovation, the press processing device is the main tool for workers, and the press device of the existing tire renovation tool is difficult to meet the use of heavy -duty truck tire renovation device. In order to control the use cost of mine truck tire, the old mine truck tire is renovated and reused, which is the best way to reduce the use cost of heavy -duty truck, and also achieves recycling and environmental protection.

[0003] Such as Chinese patent announcement CN219191361U, the disclosed invention name is "waste tire press together device", and the specific content is that the utility model relates to the field of tire renovation technology, and particularly relates to a waste tire press together device, which comprises a fixed frame, a fixed seat is fixedly connected to the inner side of the bottom end surface of the fixed frame, a fixed sleeve is fixedly connected to one side of the fixed seat, a hydraulic push rod one is fixedly connected to the inner side of the top end surface of the fixed frame, the other end of the hydraulic push rod one is fixedly connected with a movable sleeve, an adjusting motor is fixedly connected to the inner side of the top end surface of the fixed frame, the main shaft of the adjusting motor is fixedly connected with an adjusting screw through a shaft coupling, a screw rod sleeve is spirally connected to the outer side of the adjusting screw, a press sleeve is fixedly connected to one side of the screw rod sleeve, and a limiting sleeve is fixedly connected to one side of the press sleeve. Advantage: the utility model has the advantages of simple and convenient adjustment during use, high efficiency and high stability during press, and can meet the use requirements of people, and is worth promoting and using.

[0004] For example, Chinese Patent Application Publication No. CN 107283888 A, entitled "Tread Splicing Device for Front and Rear Extruded Treads of Tires for Tire Retreading", discloses a tread splicing device for front and rear extruded treads of tires for tire retreading, comprising a base and a rack, the rack being arranged above the base, a rolling device being arranged above the rack, a tire lifting device being arranged at the left end of the base, the rolling device comprising a cylinder one, a pressing roller support frame and a pressing roller, the telescopic rod of the cylinder one being connected to the middle position of the pressing roller support frame, a pressing roller being arranged at the front of the pressing roller support frame, and two pressing rollers being arranged at the rear position; a tire support rolling device being arranged at the right side of the rack, the tire support rolling device comprising a motor and a tire support device, the tire support device comprising a rolling shaft and an expansion drum, the expansion drum being sleeved on the rolling shaft, and the rolling shaft being connected to the driving shaft of the motor. The pressing roller at the front of the pressing roller support frame is used for extruding the middle position of the tread, and the pressing rollers at the rear are used for extruding the edge position of the tread, so as to ensure the splicing density of the tread and the tire, speed up the removal of bubbles between the tread and the tire, and improve the work efficiency.

[0005] For example, Chinese Patent Publication No. CN210026926U discloses a tire pressing device, which comprises a base plate and a vertical plate fixed on one side of the upper end surface of the base plate, a cylinder fixed on the inner wall of the vertical plate, a sliding block fixed on the piston rod of the cylinder, and a roller rotatably connected to the end of the sliding block away from the cylinder; a cylindrical structure boss is arranged on the upper end surface of the base plate, the boss is used for being inserted into a bearing mounting groove on the lower end surface of the hub, the outer diameter of the boss is smaller than the inner diameter of the bearing mounting groove, the bearing mounting groove and the boss are rotatably connected after the hub is placed on the base plate, an insertion pin with an outer diameter smaller than the cylindrical structure of the boss is integrally formed on the upper end surface of the boss, the insertion pin is coaxially arranged with the boss, and the insertion pin is used for being inserted into a shaft hole in the hub, the outer diameter of the insertion pin is smaller than the inner diameter of the shaft hole. The utility model can facilitate the assembly of the outer tire and the hub, improve the assembly efficiency of the outer tire and the hub, and reduce the labor intensity of the workers.

[0006] From the above-mentioned patent application disclosed technical solutions, it can be seen that a large number of devices for retreading various old tires appear, and there are many different types, among which the main one is to use a simple pressing device. Since the diameter of the truck tire is relatively large and the weight is relatively heavy, it is difficult to move it to the corresponding pressing device by manpower, and the existing retreading tire pressing or pressing device is usually arranged separately. Therefore, it is difficult to operate the pressing of large old tires, which brings inconvenience to the retreading and pressing of truck tires.

[0007] Therefore, how to provide a truck tire retreading and pressing device; in particular, for the mine truck tire of large diameter, how to carry out the special retreading and pressing device, or the structure of the pressing device is not reasonable, thereby causing the retreaded tire after pressing to enter the next process without pressing or not passing through the pressing, so that the quality of the retreaded tire is unqualified, thereby failing to meet the service life requirement.

The tire positioning part includes a lifting positioning motor 8 and a positioning tray 9. The positioning tray 9 is connected to the output shaft of the lifting positioning motor 8 and corresponds to the lower pressing roller 5 and the upper pressing roller 7 in the vertical direction.

[0029] As shown in Figures 2-3 The tire moving and hanging unit can move and hang the retreading tire that needs to be pressed. The tire moving and hanging unit includes a tire pressing and moving frame base 12, a longitudinal adjusting module 14, a transverse adjusting module 15, a mounting frame column 16, and a mounting frame assembly 17. The longitudinal adjusting module 14 and the transverse adjusting module 15 are arranged at corresponding positions on the tire pressing and moving frame base. One end of the mounting frame column 16 is fixedly connected to the tire pressing and moving frame base, and the other end is provided with the mounting frame assembly 17. The retreading tire 13 is adjusted to a corresponding position on the pressing device through the mounting frame assembly 17, so that the upper pressing roller 7 and the lower pressing roller 5 on the pressing device can press and compact the retreading tire 13 in the circumferential direction.

[0030] The width of the upper pressing roller 7 of the upper rolling pressing part corresponds to the tire width of the outer wall surface of the retreaded tire 13 in contact with the ground, and the width of the lower pressing roller 5 of the movable rolling pressing part in contact with the inner cavity of the retreaded tire 13 corresponds to the width of the inner cavity of the retreaded tire 13 for accommodating the inner tire.
