Description

Technical Field

[0001] The utility model belongs to the technical field of road rollers, and in particular relates to a heavy-tonnage roller rotating support device. Background Art

[0002] A vibratory roller is a type of engineering machinery that relies on its own gravity and vibration function to compact various types of construction and road construction materials. It is widely used in the construction of roads, railways, airports and other construction projects.

[0003] At present, vibratory rollers are mainly composed of rollers (i.e. steel wheels, pressure rollers), excitation mechanisms, vibration reduction systems, and traveling mechanisms. Among them, the rollers are the core components of the vibratory rollers. In the process of rolling and leveling the road surface, they will come into contact with sandy, semi-sticky, and sticky soils, roadbed stabilized soil, and asphalt concrete laid on the road surface. Moreover, due to the huge contact force between the rollers and the road surface materials, the roller surface will inevitably be sticky with fine sand, soil, or gravel and other debris. Therefore, after the use of the vibratory roller is completed, the operator needs to clean the roller surface in time to ensure the cleanliness of the roller surface and avoid affecting the road leveling effect. For example, Chinese patent CN202410500899.7 once provided a roller parts cleaning line and cleaning method for roller cleaning.

[0004] However, the steel wheel rotating mechanism used to support the roller in the above patent has certain defects during actual use: since the steel wheel rotating mechanism in the above patent itself does not have a lifting function, when the above steel wheel rotating mechanism is used to rotationally support the roller, the electric flat cart used to transport the roller needs to have a lifting function to ensure that the roller can be transferred between the electric flat cart and the steel wheel rotating mechanism; however, in the process of placing the roller on the electric flat cart, the roller is prone to violent collision with the support frame on the lower side or the components provided on the support frame due to the inconsistent heights of the roller groups provided on the support frames on both sides, especially when rotationally supporting heavy-tonnage rollers, which may even directly affect the service life of the roller or the steel wheel rotating mechanism in severe cases. Utility Model Content

[0005] The purpose of this utility model is to propose and design a heavy-tonnage roller rotating support device to address the problem that the roller and the roller rotating support device are prone to collision when in use in the existing roller rotating support device, and to enable it to overcome the above-mentioned problem and ensure that the heavy-tonnage roller can smoothly carry out rotation welding or internal iron filings cleaning, inner cavity cleaning and other processes.

[0006] In order to achieve the above-mentioned object, the technical solution provided by the present invention is as follows: a heavy-tonnage roller rotating support device, comprising a first support frame and a second support frame arranged in parallel, wherein the upper end of the first support frame and the upper end of the second support frame are each provided with two roller groups, and one roller group of the four roller groups is connected to a rotating drive mechanism; a support base is provided below the first support frame and the lower end of the second support frame, and a lifting cylinder is provided at the upper end of the support base, and the piston rod of the lifting cylinder extends from the upper end of the lifting cylinder and is fixedly connected to a connecting seat, and the connecting seat is fixedly connected to the corresponding support frame. At this time, since the first support frame and the second support frame in the present invention are liftable structures, when transferring the roller, the roller placed on the electric flat car can be directly lifted by the lifting action of the first support frame and the second support frame, so as to transfer the roller from the electric flat car to the roller group of the heavy-tonnage roller rotating support device, and during this process, the roller will not collide violently with the heavy-tonnage roller rotating support device due to uneven force.

[0007] Furthermore, the two roller groups provided at the upper end of support frame one are lower than the two roller groups provided at the upper end of support frame two, and a limiting mechanism is provided at the upper end of support frame one to constrain the position of the roller through the limiting mechanism to prevent the roller from slipping.

[0008] Furthermore, the limiting mechanism includes a mounting seat, the lower end of the mounting seat is fixedly mounted on the support frame, the upper end of the mounting seat is fixedly mounted with a support shaft, and the upper end of the support shaft is rotatably mounted with a limiting wheel, thereby limiting the position of the roller through contact between the limiting wheel and the end of the roller. At the same time, since the limiting wheel adopts a rotating structure, it will not hinder the normal rotation of the roller.

[0009] Furthermore, the roller group includes two fixed clamps arranged in parallel, the lower end of the fixed clamp is fixedly installed on the upper end of the corresponding support frame, the upper end of the fixed clamp is provided with at least one mounting groove, a rotating shaft is rotatably installed in the mounting groove through a bearing, and at least one roller is fixedly installed in the middle of the rotating shaft, and the roller is supported by the roller.

[0010] Furthermore, the outer surface of the roller is covered with an anti-skid cover, and the anti-skid cover can be made of anti-skid materials such as rubber to increase the friction between the roller and the roller.

[0011] Furthermore, the rotary drive mechanism includes a motor, which is installed on one side of the corresponding support frame through a motor support frame. The output shaft of the motor is connected to a driving sprocket, and the driving sprocket chain is connected to a driven sprocket. The driven sprocket is fixedly installed on the rotating shaft of the corresponding roller group, and drives the rotating shaft and rollers in the roller group to rotate.

[0012] It can be seen from the above technical solution that the utility model has the following advantages: since the utility model sets the support frame one and the support frame two as a liftable structure, compared with the existing method of lifting the roller by an electric flat car to achieve roller transfer, the structure of the utility model can ensure that both ends of the roller are always in a stressed state when transferring the roller, and the lower end of the roller is always constrained by a limiting mechanism, thereby fundamentally avoiding the situation where the roller collides violently due to uneven force during the transfer process, and ensuring that heavy-tonnage rollers can smoothly perform rotation welding or internal iron filings cleaning, inner cavity cleaning and other processes.

[0017] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the embodiments described are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0018] like Figure 1 、 Figure 2As shown, the present invention provides a heavy-tonnage roller rotary support device, which includes a parallel support frame 15 and a parallel support frame 4. Two roller groups are each provided at the upper ends of the parallel support frames 15 and 2. The roller groups include two parallel fixed plates 5, the lower ends of which are fixedly mounted to the upper ends of the corresponding support frames. The upper ends of the fixed plates 5 are provided with at least one mounting slot 7, within which a rotating shaft is rotatably mounted via a bearing. At least one roller 6 is fixedly mounted in the middle of the rotating shaft, and the roller is supported by the roller 6. Furthermore, the present invention further provides a rotation drive mechanism for connecting the end of the rotating shaft of one of the four roller groups, extending from the fixed plate 5. The rotary drive mechanism includes a motor 12, which is mounted on one side of the corresponding support frame through a motor support frame 13, and the output shaft of the motor 12 is connected to a driving sprocket 14, and the driving sprocket 14 is chain-driven with a driven sprocket 8, and the driven sprocket 8 is fixedly mounted on the rotating shaft of the corresponding roller group, so that the rotating shaft and the rollers in the roller group can rotate under the drive of the motor 12, thereby driving the roller to rotate in the corresponding direction. Moreover, as an advantage, the utility model can be provided with an anti-slip sleeve on the outer surface of the roller 6, and the anti-slip sleeve can be made of an anti-slip material such as rubber to increase the friction between the roller 6 and the roller.

[0019] A support base 1 is provided below each of the support frame 15 and the support frame 2 4. At least two lifting cylinders 2 are provided at the upper end of the support base 1. The piston rods of the lifting cylinders 2 extend from the upper ends of the lifting cylinders 2 and are fixedly connected to the connecting seats 3. The connecting seats 3 are welded and fixedly connected to the corresponding support frames. At this time, since the support frame 1 15 and the support frame 2 4 in the present invention are liftable structures, when transferring the roller from the electric flat car to the heavy-tonnage roller rotation support device, the support frame 1 15 and the support frame 2 4 can be first controlled to be at a lower height, and then the electric flat car can be controlled to move the roller to the top of the support frame 1 15 and the support frame 2 4 at a height higher than the four roller groups. Subsequently, the lifting cylinders 2 are controlled to control the support frame 1 15 and the support frame 2 4 to perform an upward movement, and the roller placed on the electric flat car is lifted until the roller is no longer in contact with the electric flat car, thereby completing the transfer of the roller from the electric flat car to the roller group of the heavy-tonnage roller rotation support device. Moreover, during this process, since both ends of the roller are always in contact with the corresponding roller group, the roller will not collide violently with the heavy-tonnage roller rotation support device due to uneven force. Conversely, when it is necessary to transfer the roller from the heavy-tonnage roller rotation support device to the electric flat car, it can first control the lifting cylinder 2 to control the support frame 1 15 and the support frame 2 4 to lower, and move the roller placed on the electric flat car downward until the middle of the roller contacts the electric flat car, thereby completing the transfer of the roller from the roller group of the heavy-tonnage roller rotation support device to the electric flat car.

[0020] In addition, as a preferred embodiment, the present invention can also make the two roller groups provided at the upper end of the support frame 15 lower than the two roller groups provided at the upper end of the support frame 2 4, that is, control the two roller groups provided at the upper end of the support frame 15 to be lower than the two roller groups provided at the upper end of the support frame 2 4 in the roller supporting state, or the height of the support frame 15 itself is lower than the height of the support frame 2 4 itself, and provide a limiting mechanism at the upper end of the support frame 15, so that it can not only ensure that the roller is in an inclined state, but also constrain the position of the roller through the limiting mechanism to prevent the roller from slipping. Specifically, the limiting mechanism includes a mounting seat 10, the lower end of the mounting seat 10 is fixedly mounted on the support frame 15, the upper end of the mounting seat 10 is fixedly mounted with a support shaft 11, the upper end of the support shaft 11 is rotatably mounted with a limiting wheel 9, and the position of the roller is limited by the contact between the limiting wheel 9 and the end of the roller. At the same time, since the limiting wheel 9 adopts a rotating structure, it will not hinder the normal rotation of the roller.
