Description

Technical Field

[0001] The present invention relates to the technology of roller equipment, and particularly to a roller equipment with adjustable counterweight. Background Art

[0002] A roller, also known as a soil compactor, is a road construction equipment mainly used for compacting the surface layer of the road surface. It adopts mechanical or hydraulic drive, can concentrate force to compact the protruding parts, has a high compaction flatness, and is suitable for asphalt pavement compaction operations. In addition, rollers are divided into two categories: steel-wheel type and tire type. According to the classification of the roller wheels, the steel-wheel type and tire type can be further divided into single-axis single-wheel, double-axis double-wheel, double-axis three-wheel, and three-axis three-wheel, etc.

[0003] In a Chinese invention patent with the publication number of CN118065209A, a roller equipment with adjustable counterweight is disclosed. When this roller equipment with adjustable counterweight is in use, first, according to actual needs, the adjustment mechanism is used to appropriately increase the weight of the first liquid tank. Then, the driving mechanism is started to drive the first convex block to do circular motion. According to the working principle of the eccentric wheel, the connecting rod drives the third convex block to do up-and-down reciprocating motion in the second limiting frame. When the third convex block is at the highest point in the second limiting frame, the driving component will drive the second convex block to be at the lowest point in the first limiting frame, operating similar to the lever principle. Therefore, when the front pressing roller rolls half a circle and the center of gravity of the driving mechanism is directly above the circumference, the first connecting rod drives the first liquid tank to be at the lowest point directly below the circumference, thereby supplementing the force exerted on the ground by the downward center of gravity of the driving mechanism. In this way, it can be avoided that the gravity exerted by the traditional roller body itself on the ground plus the downward pressure caused by the rotational inertia after weight gain are simultaneously applied to the ground, preventing the loosening of the ground material, and also preventing damage to the equipment due to the front-heavy and rear-light situation of the roller body.

[0004] When the existing equipment is in use, the traditional roller with adjustable counterweight will increase the load of the roller after increasing the weight of the drum. Since the inertia when the eccentric hammer swings downward will cause the center of gravity to move downward, driving the additional weight downward will not only increase the compaction of the road surface but may also increase the vibration force of the roller. When the vibration of the roller is too large, it may cause the loosening of the road surface material, thus affecting the compaction effect. At the same time, when adjusting the counterweight, since the counterweight is close to the edge, it may cause the equipment to tilt or lose balance, increasing the risk of tipping over. And after the adjustment is completed, it is impossible to ensure the stability of the counterweight after movement, resulting in offset due to vibration. Therefore, a roller equipment with adjustable counterweight is developed. Summary of the Invention

[0039] In this solution, the drum 11 is connected to the main body 1 through a push rod. Then, when the main body 1 moves, the drum 11 is driven to rotate and press the ground.

[0040] At the same time, a device with power output such as a motor is provided on one side of the push rod and is connected to an external control device. When the motor is started, the vibration member 12 provided at its output end is synchronously driven to rotate, thereby compacting the ground.

A plurality of driving rods 23 are provided on the outer surface of the rotating plate 22, and the plurality of driving rods 23 are evenly distributed on the outer surface of the rotating plate 22.

[0042] In this embodiment, since the connection block 211 is connected to the drum 11, when the drum 11 rotates, the connection block 211 rotates synchronously with the drum 11.

[0043] When the rotating plate 22 rotates, the driving rods 23 rotatably installed on its outer surface are synchronously driven to move, thereby driving the driving blocks 24 provided on the driving rods 23 to move.

[0044] Further, a guide groove 25 corresponding to the driving rod 23 is provided at the end of the fixed plate 21 and located on the periphery of the rotating plate 22. A driving block 24 is slidably installed on the inner wall of each guide groove 25, and the end of the driving block 24 is rotatably connected to the end of the driving rod 23; a telescopic member 28 is provided between the two symmetrically arranged driving blocks 24, and the telescopic member 28 drives multiple groups of driving blocks 24 to move.

[0045] Specifically, the telescopic member 28 is a device with a telescopic function such as an electric telescopic rod and is connected to an external control device. At the same time, when the telescopic member 28 is started, the driving block 24 arranged at its output end is synchronously driven to move. Since the end of the driving block 24 is rotatably connected to the rotating plate 22, other driving rods 23 rotatably installed on the rotating plate 22 are driven to move. The cross-section of the driving rod 23 is L-shaped.

[0046] The driving block 24 is limited by the guide groove 25, so that when the driving block 24 is stressed, it moves along the trajectory defined by the guide groove 25, and at the same time, it is ensured that the driving block 24 is offset during movement, thus affecting the overall balance.

[0047] Further, an extension rod 26 is provided at the end of the driving block 24. The end of the extension rod 26 penetrates and extends to the outside of the fixed plate 21.

[0048] Specifically, when the driving block 24 moves, the extension rod 26 arranged at its end is synchronously driven to move, and the load-bearing rod 27 is limited by the adjustment groove 261 on the extension rod 26, and at the same time, a moving trajectory is provided for the load-bearing rod 27 to ensure that the load-bearing rod 27 is not interfered during movement, thus avoiding the overall loss of balance.

[0049] Further, a protective plate 13 is slidably installed on the outer surface of the extension rod 26; a docking block 29 is rotatably installed on the inner wall of the fixed plate 21. The end of the docking block 29 penetrates and extends to the outside of the fixed plate 21, and the end of the docking block 29 is connected to the vibrating member 12.

[0050] Specifically, movable grooves are provided at both ends of the extension rod 26, and the inner wall of the movable groove is rotatably connected to the outer surface of the protective plate 13. At the same time, the end of the protective plate 13 is slidably connected to the inner wall of the roller 11. By connecting the docking block 29 to the end of the vibrating member 12, the vibrating member 12 is not interfered when it rotates.

[0051] At the same time, the upper end of the protective plate 13 is a component with a telescopic function such as a telescopic rod, so that when the protective plate 13 moves, the load-bearing rod 27 is synchronously driven to move to ensure the overall balance.

[0052] Further, the locking component 3 is assembled on the inner wall of the drum 11. At the same time, the end of the locking component 3 is in contact with the load-bearing rod 27, and the load-bearing rod 27 is fixed by the locking component 3. The locking component 3 includes a movable plate 31. A plurality of support plates 32 are arranged at the end of the movable plate 31, and the plurality of support plates 32 are evenly distributed at the end of the movable plate 31. A bottom plate 33 is arranged at one end of the support plate 32 away from the movable plate 31. A plurality of limiting grooves 34 are formed at the end of the bottom plate 33, and the plurality of limiting grooves 34 are evenly distributed at the end of the bottom plate 33.

[0053] In this embodiment, the lower end of the bottom plate 33 is slidably connected to the outer surface of the extension rod 26. At the same time, the locking component 3 moves synchronously with the load-bearing rod 27.

[0054] Further, a power rod 35 is slidably installed on the inner wall of the limiting groove 34. An extrusion plate 36 is rotatably installed at the end of the power rod 35. The outer surface of the extrusion plate 36 is rotatably connected to the outer surface of the bottom plate 33.

[0055] A pressing block 37 is rotatably installed at the lower end of the extrusion plate 36. The end of the pressing block 37 is in contact with the outer surface of the protection plate 13. A power component 38 is arranged at the middle position of the end of the bottom plate 33. The output end of the power component 38 penetrates and extends to the other end of the bottom plate 33. An adjusting plate 39 is arranged at the output end of the power component 38. The outer surface of the adjusting plate 39 is rotatably connected to the end of the power rod 35.

[0056] Specifically, the power component 38 is a device with a telescopic function such as an electric telescopic rod and is connected to an external control device. At the same time, when the power component 38 is started, the adjusting plate 39 arranged at its output end is driven to move synchronously. When the adjusting plate 39 moves, the power rod 35 rotatably installed on its outer surface is driven to move.

[0057] The outer surface of the power rod 35 is slidably connected to the inner wall of the limiting groove 34. The power rod 35 is limited by the limiting groove 34 to ensure that the power rod 35 does not shake during operation.

[0058] When the power rod 35 moves, it drives the extrusion plate 36 to rotate around the connection with the bottom plate 33, thereby pushing the pressing block 37 to tightly press on the protection plate 13.

[0059] Further, a docking groove 393 is formed at the middle position of the end of the adjusting plate 39 away from the power component 38. The inner wall of the docking groove 393 is in contact with the end of the load-bearing rod 27.

[0060] Specifically, the load-bearing rod 27 is limited by the docking groove 393 to ensure that the load-bearing rod 27 moves with the entire locking component 3. At the same time, the load-bearing rod 27 is fixed to improve the stability of the load-bearing rod 27 during operation and avoid the drum 11 from losing balance during rotation.

[0061] Furthermore, a plurality of sliding grooves 391 are formed at the end of the adjusting plate 39, and the plurality of sliding grooves 391 are evenly distributed at the end of the adjusting plate 39. At the same time, a protective block 392 is slidably mounted on the inner wall of each sliding groove 391, and the end of the protective block 392 is attached to the outer surface of the load-bearing rod 27.

[0062] Specifically, elastic components such as springs are provided on the inner wall of the sliding groove 391. The protective block 392 is squeezed by the spring, so that the protective block 392 tightly presses on the load-bearing rod 27.

[0063] When the overall balance needs to be adjusted, the corresponding load-bearing rod 27 is locked by the locking assembly 3. At the same time, the pressing block 37 is driven to tightly press on the protective plate 13, and the extended rod 26 is used to drive the fixed locking assembly 3 to move, so as to synchronously drive the corresponding load-bearing rod 27 to move, so that the overall balance is always maintained.

[0064] The control device can select a single-chip microcomputer as the control terminal. In this embodiment, the single-chip microcomputer is a typical embedded microcontroller (Micro controller Unit), which is composed of an arithmetic unit, a controller, a memory, input and output devices, etc., and is equivalent to a microcomputer. Compared with the general-purpose microprocessor used in personal computers, it emphasizes more on self-supply (without external hardware) and cost savings. Its greatest advantage is its small size, which can be placed inside the instrument, but its storage capacity is small, the input and output interfaces are simple, and the function consumption is low.

[0065] Only some exemplary embodiments of the present invention have been described by way of illustration above. Without doubt, for those of ordinary skill in the art, the described embodiments can be modified in various different ways without departing from the spirit and scope of the present invention.
