Abstract
Description
Technical Field
[0001] This invention relates to the field of lifting and transport machinery technology, and in particular to a vibration reduction and anti-shaking mechanism for a solid waste grab bucket lateral transfer vehicle. Background Technology
[0002] In solid waste treatment, overhead cranes are key lifting equipment for material handling, stacking, and sorting. Existing solid waste grab overhead cranes typically consist of a crane body that runs laterally along an upper track, a lifting winch mechanism, multiple hanging steel cables, and a grab bucket connected to the bottom of the steel cables. Operators can wirelessly control the crane from the control room. During operation, the crane stops above the waste pool, and the lifting mechanism raises and lowers the grab bucket below by raising and lowering the steel cables, thereby achieving precise grabbing, lifting, and transfer of solid waste.
[0003] However, existing solid waste grab traverse vehicles have significant drawbacks during operation. Because the grab bucket is only connected to the main body of the tractor by a flexible long steel cable, and the suspension distance is relatively long, when the tractor starts to accelerate or brakes, the grab bucket, which is suspended in the air, is prone to violent lateral swinging and shaking under the huge inertia. Since the steel cable itself cannot provide lateral rigid restraint, this shaking is difficult to decay on its own in a short time. Therefore, in actual operation, the operator must be forced to wait for the grab bucket to be completely stable before proceeding to the next step of positioning, lowering to grab, or opening the bucket to unload materials. This not only generates a lot of ineffective waiting time and greatly reduces the processing efficiency of solid waste materials, but also poses safety hazards such as the grab bucket hitting the garbage pool wall and accelerating the fatigue wear of the steel cable. Summary of the Invention
[0004] The purpose of this invention is to solve the problems in the prior art mentioned above, and to propose a vibration reduction and anti-shaking mechanism for a solid waste grab bucket lateral transfer vehicle.

[0006] Preferably, the four corners of the bottom of the gantry are rotatably connected with rollers, and the top of the gantry is provided with a track adapted to the rollers.
[0007] Preferably, a fixed pulley is installed at the top of the gantry, and the steel cable extends through the fixed pulley to directly below the gantry.
[0008] Preferably, a plurality of support ropes are provided and symmetrically arranged on both sides of the moving direction of the vehicle. The top ends of the plurality of support ropes are respectively connected to the four corners of the bottom of the vehicle. The bottom end of the support rope is connected to a telescopic spring. A protective sleeve is fitted on the surface of the support rope and is fitted on the outside of the telescopic spring. The limiting frame is located in the middle of the steel cable, and a counterweight is installed at the center of the bottom end of the limiting frame.
[0009] Preferably, the bottom end of the limiting frame is provided with an annular groove, and an annular block is hinged inside the annular groove. The guide sleeve is fixedly connected to the bottom of the annular block, and the bottom end of the guide sleeve is configured as an outwardly expanding trumpet shape.
[0010] Preferably, a damping rod is installed at the bottom end of the limiting frame, and the damping rod is circumferentially distributed on the surface of the guide sleeve.
[0011] Preferably, the plunger pump is symmetrically installed at the top of the limiting frame, the oil outlet of the plunger pump is connected to a connecting hose, the lubricating felt is fixedly installed at the top of the limiting frame, and the lubricating felt and the guide sleeve are coaxially arranged and correspond one-to-one.
[0012] Preferably, a push rod is slidably connected inside the plunger pump, a buffer spring is connected between the push rod and the plunger pump, and a corrugated protective tube is connected to the surface of the plunger pump, with the corrugated protective tube disposed outside the push rod and the buffer spring.
[0013] Preferably, a clamping block is fitted onto the surface of the push rod at the end away from the plunger pump, and a steel wire is connected to the surface of the clamping block. The end of the steel wire away from the clamping block is connected to the surface of the support rope.
[0014] Preferably, the plunger pump is equipped with an oil inlet at its top, and an oil injection pipe is inserted into the inside of the oil inlet. The oil injection pipe is wound around the surface of the support rope, and the top of the oil injection pipe extends upward and is located at the bottom of the vehicle.
[0015] Compared with the prior art, the present invention provides a vibration reduction and anti-shaking mechanism for a solid waste grab bucket lateral transfer vehicle, which has the following beneficial effects: 1. The vibration reduction and anti-shaking mechanism of this solid waste grab bucket lateral transfer vehicle uses support ropes and counterweights to form a stable suspended damping base for the limiting frame in mid-air. Combined with a universal guide sleeve hinged to an annular groove and circumferentially distributed damping rods, when the vehicle accelerates or decelerates, causing severe lateral swaying of the grab bucket and steel cable, the guide sleeve tilts with the steel cable and forcefully compresses the outer damping rods. The rapid contraction of the damping rods dissipates the kinetic energy of the swaying steel cable. This design provides flexible yet strong lateral restraint to the suspended steel cable, forcing the swaying grab bucket to quickly attenuate its amplitude and return to a vertically stable state. This significantly reduces the time operators spend waiting for the grab bucket to stabilize, effectively improving the efficiency and safety of solid waste processing.
[0016] 2. The vibration reduction and anti-shaking mechanism of this solid waste grab bucket traverse vehicle utilizes the inertial fluctuations generated by the limiting frame during the crane's operation and anti-sway vibration reduction process to drive the support rope to pull the steel wire, thereby driving the push rod in the plunger pump to slide back and forth to pump oil, thus achieving lubrication of the steel cable. This design does not require additional electricity or complex electronic control drive devices, and also avoids the inconvenience of maintenance in high-altitude working environments. At the same time, it can convert the mechanical vibration of the crane into oil pumping power, so that the lubricating oil continuously wets the lubricating felt, automatically and evenly rubbing and lubricating the surface of the steel cable during lifting operations, effectively reducing the frictional resistance of the steel cable during operation and significantly extending the fatigue life of the steel cable.

[0019] The technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present invention. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments.
[0020] In the description of this invention, it should be understood that the terms "upper", "lower", "front", "rear", "left", "right", "top", "bottom", "inner", "outer", etc., indicate the orientation or positional relationship based on the orientation or positional relationship shown in the accompanying drawings. They are only for the convenience of describing this invention and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limitations on this invention.
[0021] Reference Figures 1-10The vibration reduction and anti-shaking mechanism of the solid waste grab bucket lateral movement vehicle includes a gantry frame 1, a trolley 2 mounted on the top of the gantry frame 1, rollers 21 rotatably connected to the four corners of the bottom of the trolley 2, a track adapted to the rollers 21 mounted on the top of the gantry frame 1 to facilitate the trolley 2's acceleration, deceleration and lateral movement along the track, a winding machine 31 mounted on the top of the trolley 2, a steel cable 32 connected to the surface of the winding machine 31, a fixed pulley 33 mounted on the top of the gantry frame 1, the steel cable 32 passing through the fixed pulley 33 and extending to directly below the trolley 2, the bottom end of the steel cable 32 connected to a grab bucket 34, and the bottom end of the trolley 2 connected to... A support rope 41 is connected to the bottom end of the support rope 41, and a limit frame 43 is connected to the bottom end of the limit frame 43. A guide sleeve 47 is provided at the bottom end of the limit frame 43. The guide sleeve 47 is fitted over the outside of the steel cable 32, so that the steel cable 32 passes through the inside of the guide sleeve 47 and is laterally constrained during the lifting and lowering process. A plunger pump 51 is installed at the top end of the limit frame 43, and a lubricating felt 53 is installed at the top end of the limit frame 43. The output end of the plunger pump 51 is connected to the inside of the lubricating felt 53. The lubricating felt 53 is fitted over the surface of the steel cable 32 so that the pumped lubricating oil can be directly applied to the surface of the up-and-down moving steel cable 32.
[0022] Reference Figures 3-6 Several support ropes 41 are symmetrically arranged on both sides of the moving direction of the gantry 2. The top ends of the support ropes 41 are respectively connected to the four corners of the bottom of the gantry 2. The support ropes 41 at the four corners, together with the counterweight 44 installed at the center of the bottom of the limiting frame 43, provide downward gravity, so that the limiting frame 43 can maintain a relatively stable suspension state in mid-air, thus acting as a stable damping base. The surface of the support ropes 41 is covered with a protective sleeve 42. The telescopic spring is connected between the support ropes 41 and the limiting frame 43. When the suspended limiting frame 43 fluctuates slightly due to impact or inertia, the telescopic spring can stretch and contract accordingly. The protective sleeve 42 is fitted on the outside of the telescopic spring. The limiting frame 43 is located in the middle of the steel cable 32. The counterweight 44 is installed at the center of the bottom of the limiting frame 43.
[0023] The bottom end of the limiting frame 43 is provided with an annular groove 45, and an annular block 46 is hinged inside the annular groove 45. Through this hinge structure, the guide sleeve 47 can tilt and swing in all directions following the deflection direction of the internal steel cable 32. The guide sleeve 47 is fixedly connected to the bottom of the annular block 46. The bottom end of the guide sleeve 47 is set as an outwardly expanding trumpet shape, which reduces the wear caused by the friction between the steel cable 32 and the inner wall of the guide sleeve 47 during tilting and swaying. A damping rod 48 is installed at the bottom end of the limiting frame 43. The damping rod 48 is circumferentially distributed on the surface of the guide sleeve 47. When the steel cable 32 tilts and drives the guide sleeve 47 to swing outward, the outer wall of the guide sleeve 47 will strongly squeeze the corresponding damping rod 48, so that the damping rod 48 will quickly undergo damping contraction after being compressed, thereby consuming the kinetic energy of the swing of the steel cable 32 and providing flexible constraint.
[0024] Reference Figures 6-10 The plunger pump 51 is symmetrically installed at the top of the limiting frame 43. The oil outlet end of the plunger pump 51 is connected to the connecting hose 52. The lubricating felt 53 is fixedly installed at the top of the limiting frame 43. The lubricating felt 53 and the guide sleeve 47 are coaxially arranged and correspond one to one. The other end of the connecting hose 52 is connected to the lubricating felt 53, so that the lubricating oil pumped out by the plunger pump 51 can fully flow into and wet the interior of the lubricating felt 53.
[0025] A push rod 54 is slidably connected inside the plunger pump 51. The push rod 54 slides back and forth within the plunger pump 51 to continuously perform the pumping action. A buffer spring 55 connects the push rod 54 and the plunger pump 51. When the push rod 54 is not pulled, the buffer spring 55 pushes the push rod 54 back to its original position by its own elastic force. A corrugated protective tube 56 is connected to the surface of the plunger pump 51. The corrugated protective tube 56 can prevent external oil contaminants from contacting the push rod 54 and obstructing its movement. The corrugated protective tube 56 is located outside the push rod 54 and the buffer spring 55. A clamping block 57 is sleeved on the surface of the push rod 54 away from the plunger pump 51. A steel wire 58 is connected to the surface of the clamping block 57. The end of the steel wire 58 away from the clamping block 57 is connected to... The surface of the support rope 41 allows the support rope 41 and the telescopic spring to simultaneously pull the steel wire 58 wrapped around it when the support rope 41 and the telescopic spring are displaced and deformed, thereby pulling the push rod 54 to slide outward against the elastic force of the buffer spring 55; the top of the plunger pump 51 is equipped with an oil inlet 59, and an oil injection pipe 510 is inserted into the inside of the oil inlet 59. The oil injection pipe 510 is wrapped around the surface of the support rope 41, and the top of the oil injection pipe 510 extends upward and is located at the bottom of the gantry 2. This pipeline layout allows the operator to easily inject oil into the oil injection pipe 510 extending to the bottom of the gantry 2 by simply standing on the top of the gantry 1 during shutdown, thereby replenishing lubricating oil into the plunger pump 51 in mid-air from a distance.
[0026] In this invention, when the solid waste grab bucket lateral movement vehicle accelerates, decelerates, or brakes suddenly, the grab bucket 34 at the bottom is prone to violently swinging the steel cable 32 due to its huge inertia. At this time, the limiting frame 43, under the combined action of the support ropes 41 at the four corners and the downward gravity of the counterweight 44, can maintain a relatively stable suspended state in mid-air, thus acting as a stable damping base. When the steel cable 32 tilts and sways, it will inevitably come into contact with and be squeezed against the inner wall of the guide sleeve 47 sleeved on its outside. Because the guide sleeve 47 is fixedly connected to the bottom of the annular block 46, and the annular block 46 is hinged inside the annular groove 45 at the bottom of the limiting frame 43, the guide sleeve 47 can tilt and swing in all directions following the deflection direction of the steel cable 32. During the outward swing of the guide sleeve 47, its outer wall will strongly squeeze the damping rod 48 distributed on its surface. After being compressed, the damping rod 48 will quickly contract and consume the kinetic energy of the swing of the steel cable 32, thereby providing a flexible and strong lateral constraint on the steel cable 32, forcing the swaying grab bucket 34 to quickly attenuate the amplitude and return to a vertically stable state, greatly reducing the ineffective time for the operator to wait for the grab bucket to stabilize, and effectively improving the efficiency of garbage grabbing.
[0027] During the operation and anti-sway vibration reduction of the trolley 2, the suspension limit frame 43 will experience slight fluctuations due to the impact of the steel cable 32 and its own inertia, thereby causing the telescopic spring connected to the bottom of the support rope 41 to stretch and contract. Simultaneously, as the support rope 41 deforms, it pulls on the steel wire 58 wrapped around its surface. The other end of the steel wire 58 is connected to the push rod 54 via the clamp 57. Therefore, when the steel wire 58 is pulled, it overcomes the elasticity of the buffer spring 55, pulling the push rod 54 back and forth within the plunger pump 51, causing the plunger pump 51 to continuously pump oil. At this time, the lubricating oil pumped from the outlet of the plunger pump 51 flows through the connecting hose 52 and fully wets the interior of the lubricating felt 53. Due to the connection between the lubricating felt 53 and the guide sleeve 47... The cable 32 is coaxially mounted on the surface of the steel cable 32. When the winding machine 31 winds up and unwinds the steel cable 32, driving the grab bucket 34 to move up and down, the surface of the moving steel cable 32 will continuously rub against the lubricating felt 53 soaked in lubricating oil, thereby achieving automatic lubrication of the surface of the steel cable 32. This process not only effectively reduces the wear caused by the friction between the steel cable 32 and the inner wall of the trumpet-shaped guide sleeve 47 when tilting and shaking, and extends the fatigue life of the steel cable 32, but also recovers the mechanical vibration of the crane during operation as the power for pumping oil. Self-lubrication maintenance can be achieved without additional power connection. During shutdown, the operator can stand on the top of the gantry 1 to inject oil into the oil injection pipe 510 extending to the bottom of the overhead crane 2, thereby adding lubricating oil to the inside of the plunger pump 51.

Any equivalent substitutions or modifications made by those skilled in the art within the scope of the technology disclosed in the present invention, based on the technical solution and inventive concept of the present invention, should be covered within the scope of protection of the present invention.
