Description

Technical Field

[0001] This utility model relates to the field of road rollers, and in particular to a road roller stop structure. Background Technology

[0002] A road roller is a heavy-duty machine used for compacting materials such as soil, asphalt, and concrete. It is widely used in road construction, civil engineering, and building construction, primarily to increase the density and smoothness of the ground or road surface by applying pressure. The operation of a road roller consists of two parts: movement and compaction. Movement is typically achieved using a diesel engine mounted on the roller, which drives the rotation of the rear wheels. The compaction process is generally achieved through an eccentric structure mounted on the front wheels, with a separate drive mechanism for this part providing the rotational power.

[0003] The stopping structure of a road roller includes two aspects. The first is the braking of the entire road roller, which is generally achieved through a disc or drum brake structure, and there are relatively mature structures available at present. The second is the stopping of the eccentric structure. Currently, there are few designs for eccentric structure stopping structures, and the characteristics of the eccentric wheel are not considered. This makes it impossible to quickly reduce the speed, and the energy waste is also obvious. Utility Model Content

[0004] The main purpose of this utility model is to provide a stop structure for a road roller, which aims to solve the problem that there are few stop structures for eccentric structures in road rollers, and the characteristics of eccentric wheels are not considered, which makes it impossible to quickly reduce the speed while wasting energy.

[0005] To achieve the above objectives, this utility model provides a road roller stop structure, comprising: A cylindrical structure includes an outer cylinder and an inner cylinder coaxially connected inside the outer cylinder. A sealing plate is provided at both ends of the outer cylinder, and multiple shock absorbers are connected to the sealing plates at both ends of the inner cylinder. Two planar bearings are provided, each corresponding to one of the sealing plates. Each planar bearing includes an inner ring and an outer ring that are rotatably disposed with respect to each other. The outer ring is connected to the sealing plate, and the inner ring is connected to an external fixing structure. The motor is connected to an external fixed structure and fixed to one end of the cylindrical structure, specifically the inner ring. A stop is provided at the other end of the cylindrical structure and includes a telescopic rod and a second planar bearing. The second planar bearing is slidably installed on the inner wall of the inner cylinder along the length direction. The second planar bearing includes an inner ring and an outer ring that are rotatably arranged with each other. The telescopic rod is installed on the inner ring and its output end is connected to the outer ring. The vibrating part includes a plane bearing three connected to an external fixed structure and a central shaft passing through the cylindrical structure. The two ends of the central shaft are respectively connected to the motor and the plane bearing three. Multiple eccentric blocks and a transmission disc correspondingly arranged inside the inner ring two are fixed on the central shaft. The telescopic rod drives the second planar bearing to engage and disengage with the transmission disc, and the mass of the second inner ring is more than twice the total mass of the multiple eccentric blocks.

[0006] Furthermore, the transmission disc is fixed in the circumferential direction and elastically clamped in the length direction on the central shaft, wherein the transmission disc is compressed when it contacts the inner ring two.

[0007] Furthermore, a counterweight ring is symmetrically provided on the inner wall of the inner cylinder at one end of the cylindrical structure for the second planar bearing.

[0013] Furthermore, the outer wall of the second planar bearing is fitted with the inner wall of the inner cylinder in a spline configuration.

[0014] Furthermore, the telescopic rod can be driven by hydraulic pressure, pneumatic pressure, or an electric motor.

[0015] The roller stop structure provided by this utility model includes a second planar bearing slidably mounted on the inner wall of the inner cylinder along its length. A telescopic rod is mounted on the second inner ring, with its output end connected to the second outer ring. The telescopic rod's extension and retraction drive the second planar bearing to slide back and forth. A transmission disc and multiple eccentric blocks are mounted on the central shaft. The rotation of the eccentric blocks achieves a vibration effect. The transmission disc is correspondingly positioned on the inner side of the second inner ring. The telescopic rod drives the second planar bearing to engage with the transmission disc.

[0020] Reference Figures 1 to 5 In one embodiment of this utility model, a road roller stop structure includes: The cylindrical structure 100 includes an outer cylinder 110 and an inner cylinder 120 coaxially connected within the outer cylinder 110. A sealing plate 130 is provided at both ends of the outer cylinder 110, and multiple shock absorbers 140 are connected to the sealing plate 130 at both ends of the inner cylinder 120. Two planar bearings 200 are respectively provided for one of the sealing plates 130. Each planar bearing 200 includes an inner ring 210 and an outer ring 220 that are rotatably disposed with respect to each other. The outer ring 220 is connected to the sealing plate 130, and the inner ring 210 is connected to an external fixing structure. Motor 300 is connected to an external fixed structure and fixed to the inner ring 210 at one end of the cylindrical structure 100; A stop is provided at the other end of the cylindrical structure 100 and includes a telescopic rod 410 and a second planar bearing 500. The second planar bearing 500 is slidably mounted on the inner wall of the inner cylinder 120 along the length direction. The second planar bearing 500 includes an inner ring 510 and an outer ring 520 that are rotatably arranged with each other. The telescopic rod 410 is mounted on the inner ring 510 and its output end is connected to the outer ring 520. The vibrating part includes a plane bearing 610 connected to an external fixed structure and a central shaft 620 penetrating the cylindrical structure 100. The two ends of the central shaft 620 are respectively connected to the motor 300 and the plane bearing 610. A plurality of eccentric blocks 630 and a transmission disc 640 correspondingly arranged inside the inner ring 510 are fixed on the central shaft 620. The telescopic rod 410 drives the second planar bearing 500 to engage and disengage with the transmission disc 640, and the mass of the second inner ring 510 is more than twice the total mass of the multiple eccentric blocks 630.

[0021] In existing technologies, the stop mechanism for the eccentric structure of road rollers is rarely designed, and the characteristics of the eccentric wheel are not considered. As a result, it is impossible to quickly reduce the speed, and energy waste is also obvious.

[0022] The roller stop structure provided by this utility model includes a cylinder structure 100 comprising an outer cylinder 110 and an inner cylinder 120 coaxially connected within the outer cylinder 110. The outer cylinder 110 interacts with an external base surface, while the inner cylinder 120 provides structural strength. A sealing plate 130 is provided at each end of the outer cylinder 110. Multiple shock absorbers 140 are connected to the sealing plates 130 at each end of the inner cylinder 120. The sealing plates 130 rotate with the rotation of the cylinder structure 100, and the shock absorbers 140 work to achieve a damping effect. Different buffering and damping effects can be achieved by replacing and adjusting the shock absorbers 140.

[0023] Two planar bearings 200 are respectively disposed corresponding to one end plate 130. Each planar bearing 200 includes an inner ring 210 and an outer ring 220 that are rotatably arranged relative to each other. The bearing structure between the inner ring 210 and the outer ring 220 can be varied; for example, ball bearings can be provided between the inner ring 210 and the outer ring 220 to achieve smooth relative rotation. The outer ring 220 is connected to the end plate 130, thus supporting the end plate 130 while rotating. The inner ring 210 is connected to an external fixed structure, such as a wheel fixing arm 010, so that the planar bearings 200 can be supported. The rotation of the cylindrical structure 100 is achieved through the two planar bearings 200.

[0024] The motor 300 is connected to an external fixed structure and fixed to an inner ring 210 at one end of the cylindrical structure 100 along its length. For example, the base of the motor 300 is connected to the wheel fixing arm 010 and also to the inner ring 210 at that location. The motor 300 itself does not rotate, and the inner ring 210 at that location also does not rotate.

[0025] A stop is located at the other end of the cylindrical structure 100 along its length. The stop includes a telescopic rod 410 and a second flat bearing 500. The second flat bearing 500 is slidably mounted on the inner wall of the inner cylinder 120 along its length. The second flat bearing 500 includes an inner ring 510 and an outer ring 520 that are rotatably disposed relative to each other. The outer ring 520 can engage with the inner wall of the inner cylinder 120 via a spline or similar mechanism, thereby achieving smooth sliding. The telescopic rod 410 is mounted on the inner ring 510 and its output end is connected to the outer ring 520. The telescopic rod 410 can be driven by hydraulic or electric motor mechanisms. The telescopic rod 410's extension and retraction movement drives the second flat bearing 500 to slide reciprocally.

[0026] The vibrating unit includes a central shaft 620 and a surface bearing 610. The surface bearing 610 is fixed to an external fixing structure, such as a wheel fixing arm 010. One end of the central shaft 620 is connected to the output end of the motor 300, and the other end is connected to the surface bearing 610, thus enabling the central shaft 620 to drive the motor 300 to rotate. A transmission disc 640 and multiple eccentric blocks 630 are provided on the central shaft 620, and the vibration effect is achieved through the rotation of the eccentric blocks 630. The transmission disc 640 is correspondingly located inside the inner ring 510.

[0027] The telescopic rod 410 drives the second plane bearing 500 to reciprocate, thereby causing the inner ring 510 of the second plane bearing 500 to engage and disengage with the transmission disc 640. When the mass of the inner ring 510 is more than twice the total mass of the multiple eccentric blocks 630, the inner ring 510 operates similarly to a flywheel.

[0028] During operation, at the start of compaction, the telescopic rod 410 drives the second flat bearing 500 to separate from the transmission disc 640, and the motor 300 starts working. At this time, the second flat bearing 500 installed in the inner cylinder 120 does not participate in the operation of the roller, but only provides a counterweight effect. After the compaction is completed, the motor 300 stops working, and the telescopic rod 410 drives the second flat bearing 500 to engage with the transmission disc 640. At this time, the second inner ring 510 receives and stores the kinetic energy of the eccentric block 630 through the transmission disc 640. The mass of the second inner ring 510 is balanced in the circumferential direction, and the eccentric motion effect of the vibrating part is weakened. Therefore, the larger the mass of the second inner ring 510 relative to the eccentric block 630, the better the stopping effect. At the same time, the second inner ring 510 can act as a gyroscope, which improves the stability of the entire wheel. In some work processes, when the compaction work begins, if the internal ring 2 510 stores energy, the telescopic rod 410 first drives the plane bearing 2 500 to engage with the transmission disc 640 to transfer part of the kinetic energy to the eccentric block 630. Then, the telescopic rod 410 drives the plane bearing 2 500 to separate from the transmission disc 640, starting the operation of the motor 300.

[0029] In summary, the second planar bearing 500 is slidably mounted on the inner wall of the inner cylinder 120 along its length. The telescopic rod 410 is mounted on the second inner ring 510, and its output end is connected to the second outer ring 520. The telescopic rod 410 drives the second planar bearing 500 to slide back and forth. A transmission disc 640 and multiple eccentric blocks 630 are mounted on the central shaft 620. The rotation of the eccentric blocks 630 achieves a vibration effect. The transmission disc 640 is correspondingly positioned inside the second inner ring 510. The telescopic rod 410 drives the second planar bearing 500 to engage with the transmission disc 640. At this time, the second inner ring 510 receives and stores the kinetic energy of the eccentric blocks 630 through the transmission disc 640, achieving a stopping effect. Simultaneously, the second inner ring 510 functions as a gyroscope, thus improving the stability of the entire cylinder structure 100.

[0030] In one embodiment, the transmission disk 640 is fixed in the circumferential direction and elastically clamped in the longitudinal direction on the central shaft 620, wherein the transmission disk 640 is compressed when it contacts the inner ring 510.

[0031] In this embodiment, the movable arrangement of the transmission disc 640 in the length direction provides a clutch-like buffer structure for the contact process between the transmission disc 640 and the inner ring 510, resulting in a smoother engagement process. For example, one side of the transmission disc 640 is an elastic element, and the other side is a fixed ring.

[0032] Reference Figures 3 to 4 In one embodiment, a counterweight ring 122 is symmetrically provided on the inner wall of the inner cylinder 120 at one end of the cylindrical structure 100, where the planar bearing 500 is located.

[0033] In this embodiment, the counterweight ring 122, which is symmetrically arranged with respect to the second planar bearing 500, allows the mass of the cylindrical structure 100 to be uniform without requiring adjustment of the mass density of the second planar bearing 500. The counterweight ring 122 can be fixed to the inner cylinder 120 by welding or bolting.

[0034] Reference Figures 3 to 4 In one embodiment, a plurality of support plates 121 are provided around the outer wall of the inner cylinder 120, and the outer edge of the support plates 121 abuts against the inner wall of the outer cylinder 110.

[0035] In this embodiment, the support plate 121 provides support for the outer cylinder 110, thereby enhancing its structural strength. An elastic buffer structure can also be provided between the support plate 121 and the outer cylinder 110 to prevent damage to the outer cylinder 110 from the support plate 121.

[0036] In one embodiment, the number of telescopic rods 410 is two or four, and they are evenly distributed circumferentially on the planar bearing 500.

[0037] In this embodiment, the number of telescopic rods 410 is increased, thereby improving the stability of the movement of the second planar bearing 500.

[0038] In one embodiment, the output end of the telescopic rod 410 is connected to the outer ring 520 via an adapter frame, and the adapter frame and the outer ring 520 form multiple connection points in the circumferential direction.

[0039] In this embodiment, the adapter frame enables a telescopic rod 410 to stably push the outer ring 520.

[0040] In one embodiment, the eccentric block 630 is detachably mounted on the central shaft 620.

[0041] In this embodiment, different working conditions are met by replacing and adjusting the eccentric block 630. The eccentric block 630 can be connected to the central shaft 620 by bolts or the like.

[0042] In one embodiment, the inner cylinder 120 and the outer cylinder 110 are connected by welding.

[0043] In this embodiment, the inner cylinder 120 and the outer cylinder 110 are connected by welding, which provides structural stability and reduces the structural requirements on the outer cylinder 110. When maintenance is needed later, the welded structure can be removed.

[0044] In one embodiment, the outer wall of the second planar bearing 500 is fitted with the inner wall of the inner cylinder 120 in a spline configuration.

[0045] In this embodiment, the fit of the second planar bearing 500 is limited, so that the sliding process of the second planar bearing 500 is smoother. The specific spline fit size and model are designed and limited according to the actual use requirements.

[0046] In one embodiment, the telescopic rod 410 is driven by hydraulic pressure, pneumatic pressure, or an electric motor.

[0047] In this embodiment, several typical operating modes of the telescopic rod 410 are provided.

[0048] In summary, the roller stop structure provided by this utility model has a second planar bearing 500 slidably mounted on the inner wall of the inner cylinder 120 along its length. A telescopic rod 410 is mounted on the second inner ring 510, with its output end connected to the second outer ring 520. The telescopic rod 410 drives the second planar bearing 500 to slide back and forth. A transmission disc 640 and multiple eccentric blocks 630 are provided on the central shaft 620. The rotation of the eccentric blocks 630 achieves a vibration effect. The transmission disc 640 is correspondingly located on the inner side of the second inner ring 510. The telescopic rod 410 drives the second planar bearing 500 to engage with the transmission disc 640. At this time, the second inner ring 510 receives and stores the kinetic energy of the eccentric blocks 630 through the transmission disc 640, achieving a stop effect. Simultaneously, the second inner ring 510 acts as a gyroscope, improving the stability of the entire cylinder structure 100.
