Description

Technical Field

[0001] The present application relates to the technical field of lubrication of a trolley for a bridge-type grab ship unloader, and in particular to an automatic lubrication system for a trolley assembly for a bridge-type grab ship unloader. Background Art

[0002] Among the equipment used for unloading bulk cargo at port terminals, the bridge grab ship unloader is the most commonly used type of ship unloading equipment; the ship unloader trolley is used to support the grab bucket and cargo, and runs on the arm in the main structure of the ship unloader to transfer the cargo from the cabin to the hopper in the middle of the ship unloader, and then transport the cargo to the rear yard through the belt conveyor under the hopper.

[0003] Among them, the trolley and the grab and cargo supported by the trolley are the active load of the ship unloader. In order to reduce the weight of the active load and reduce the weight of the supporting steel structure of the whole machine, a non-powered trolley is generally used.

[0004] As attached Figure 1 The trolley only supports the weight of the grab bucket and cargo, and transfers the weight to the arm structure of the ship unloader through the wheels at the four corners of the trolley. The lifting and lowering of the grab bucket and cargo, and the forward and backward movement of the trolley along the arm structure are all controlled by the movement of the four lifting wire ropes. The trolley is a purely mechanical component, and no electricity is supplied to the trolley. However, the trolley is equipped with rotating parts such as the redirecting pulley, running wheel, and anti-deviation horizontal wheel of the lifting wire rope. Each pulley, running wheel, horizontal wheel, etc. are supported on a fixed shaft through rolling bearings. During the unloading process, each component rotates continuously. Because there is no electricity supply on the trolley, it is impossible to set an electric-driven automatic lubrication device for each rotating part on the trolley. It is necessary to manually add grease to each lubrication point manually, which is labor-intensive and easily causes the redirecting pulley, trolley running wheel, and horizontal wheel bearings on the trolley to lack grease, resulting in easy damage to the bearings. Summary of the invention

[0005] In order to realize automatic lubrication of the trolley without electricity and reduce the burden of manual lubrication, the present application provides an automatic lubrication system for a trolley assembly for a bridge grab ship unloader.

[0006] The automatic lubrication system of a trolley assembly for a bridge-type grab ship unloader provided in the present application adopts the following technical solution: An automatic lubrication system for a trolley assembly for a bridge grab ship unloader comprises an oil distributor, the oil distributor is mounted on the trolley, the oil distributor is connected to a plurality of oil pipes, a plurality of the oil pipes are respectively connected to the lubrication points of the trolley, a first gear pump is mounted on the trolley, the oil outlet of the first gear pump is connected to the oil inlet of the oil distributor, the oil inlet of the first gear pump is connected to an oil storage tank, a driving member is arranged on the trolley, the trolley drives the driving member to operate while moving, and the driving member controls the first gear pump to extract lubricating oil from the oil storage tank to the oil distributor.

[0007] By adopting the above technical solution, when the trolley moves, the trolley controls the driving member to operate, and the driving member drives the first gear pump to extract the lubricating oil in the lubricating oil tank to the oil distributor. The oil distributor can adjust the grease injection amount of each lubrication point, so that each lubrication point of the trolley can be fully lubricated, and the grease injection time of each lubrication point is synchronized with the running time of the trolley, that is, it can ensure that the grease injection amount of each point meets the operation requirements and can also avoid the waste caused by excessive grease injection into the lubrication point; There is no need to set up an additional power drive device, and the lubricating oil in the oil storage barrel can meet the lubrication needs for a long time, reducing the labor intensity of personnel.

[0008] Optionally, the driving member includes a first pulley and a second pulley, the first pulley is coaxially fixed to one of the wheels of the trolley, the second pulley is connected to the first gear pump, and the first pulley and the second pulley form a transmission connection through a first transmission belt.

[0009] By adopting the above technical solution, the wheels of the trolley rotate when the trolley moves, the wheels of the trolley drive the first pulley to rotate, the first pulley drives the second pulley to rotate through the first transmission belt, thereby realizing the operation of the first gear pump, and realizing that the first gear pump is synchronously started to supply oil while the trolley moves.

[0010] Optionally, the oil outlet end of the first gear pump is connected to an oil distribution tank, and the oil outlet end of the oil distribution tank is connected to the oil inlet end of the oil distributor.

[0011] By adopting the above technical solution, the oil distribution tank can play a buffering role, making the oil pressure and flow in the lubrication system more stable. After the lubricating oil is transported to the oil distribution tank, it is then supplied to the oil distributor through the oil distribution tank. This setting can prevent the unstable lubricating oil supply caused by pressure fluctuations or uneven flow, thereby ensuring that each lubrication point obtains continuous and stable lubrication.

[0012] Optionally, two oil distributors are provided, and the two oil distributors are symmetrically arranged about the center line of the length direction of the trolley, and several oil pipes of the oil distributors are connected to the lubrication points of the walking wheels, pulleys and horizontal wheels on one side of the center line of the length direction of the trolley.

[0013] By adopting the above technical solution, by symmetrically arranging the oil distributors on both sides of the trolley, it can be ensured that the lubricating oil is evenly distributed to all parts that need lubrication. Each distributor is responsible for the lubrication of the parts on the corresponding side, avoiding the problem of uneven pressure or unbalanced distribution of lubricating oil that may be caused by a single distributor, thereby ensuring that each lubrication point is fully lubricated; The symmetrically arranged distributor design effectively reduces the length of the oil pipeline. Compared with arranging pipelines from a single central location to each lubrication point, this symmetrical design reduces the intersection and branching of pipelines, and reduces the complexity of pipeline installation and maintenance. In addition, the shorter pipeline path reduces the resistance to oil delivery and improves the efficiency of lubricant delivery.

[0014] Optionally, the first pulley is coaxially fixed on a traveling wheel of the trolley, and a second gear pump is installed on the trolley. The oil inlet end of the gear pump is connected to the oil storage tank. The traveling wheel of the trolley on which the first pulley is fixed is also provided with a connecting piece, and the connecting piece is connected to the second gear pump, and the second gear pump is connected to the oil distribution tank. When the trolley moves, the connecting piece is driven to operate, and the connecting piece controls the second gear pump to extract lubricating oil from the oil storage tank to the oil distribution tank.

[0015] By adopting the above technical solution, the second gear pump is controlled to operate through the linkage when the trolley moves, so that more grease can be extracted into the oil distribution tank each time it moves, and the rotation speed of the bidirectional gear pump will be low when the trolley moves at a low frequency or a slow speed, resulting in insufficient grease supply due to insufficient oil in the oil distribution tank. And such redundant design can prevent that when one of the gear pumps is damaged, the other gear pump can continue to supply oil, thereby further improving the lubrication effect and improving the stability of the lubrication system.

[0016] Optionally, the linkage member includes a linkage shaft, the linkage shaft is coaxially fixed on the walking wheel, the linkage shaft is coaxially fixed with a first transmission wheel, the second gear pump is connected to a second transmission wheel, and the first transmission wheel and the second transmission wheel are rotationally connected via a second transmission belt.

[0017] By adopting the above technical solution, when the walking wheel rotates, it drives the connecting shaft to rotate, the connecting shaft drives the first transmission wheel to rotate, and the first transmission wheel drives the second transmission wheel to rotate through the second transmission belt, so that the second gear pump and the first gear pump can simultaneously extract the oil in the oil storage tank into the oil distribution tank.

[0018] Optionally, the linkage shaft includes a first coupling shaft and a second coupling shaft, the first coupling shaft is coaxially fixed on the walking wheel, the second coupling shaft is connected to the first coupling shaft through a connecting assembly, the second coupling shaft is rotationally connected to the trolley, the first transmission wheel is coaxially fixed on the second coupling shaft, the trolley is provided with an energy storage assembly, and the second coupling shaft is connected to the energy storage assembly; When the trolley moves, the connecting assembly controls the second coupling shaft to connect with the first coupling shaft, and the travel wheel moves to control the first coupling shaft and the second coupling shaft to rotate simultaneously. At this time, the second coupling shaft controls the energy storage assembly to store energy; When the trolley brakes, the connecting component controls the second coupling shaft to be disconnected from the first coupling shaft, and the energy storage component releases energy to control the second coupling shaft to rotate independently.

[0019] By adopting the above technical solution, it is achieved that when the trolley is moving, the first gear pump and the second gear pump can operate simultaneously to extract oil into the oil distribution tank and store energy for the energy storage component; When the trolley is braked, the first coupling and the coupling are disconnected, and the energy storage component releases energy to drive the second gear pump to continue to operate independently, continuously supplying oil to the oil distribution tank, thereby ensuring that there is sufficient lubricating oil in the oil distribution tank and further improving the stability of the lubrication system.

[0020] Optionally, the energy storage assembly includes a winch wheel, which is coaxially fixed on the second coupling shaft. An energy storage sleeve is installed on the trolley, and a piston is slidingly sealed inside the energy storage sleeve. A traction rope is wrapped around the winch wheel, one end of the traction rope is fixed on the winch wheel, and the other end of the traction rope is connected to the piston.

[0021] By adopting the above technical solution, when the trolley is moving, the first coupling shaft drives the second coupling shaft to rotate, the second coupling shaft drives the winch wheel to reel in, and the traction rope pulls the piston to move. At this time, the internal air pressure of the energy storage sleeve is lower than the atmospheric pressure, and the energy storage sleeve is in an energy storage state; When the trolley stops, the connecting assembly controls the first coupling and the second coupling to disconnect. At this time, under the action of atmospheric pressure, the piston is pushed into the energy storage sleeve, thereby realizing the independent rotation of the second coupling and controlling the second gear pump to extract oil into the oil distribution tank.

[0022] Optionally, the connection assembly includes an electromagnetic clutch, the stator of the electromagnetic clutch is fixed on the first coupling shaft, the rotor of the electromagnetic clutch is fixed on the second coupling shaft, the electromagnetic clutch has a built-in battery module, a solar panel for charging the battery module is installed on the trolley, and the electromagnetic clutch is also provided with a microcontroller and a wireless signal receiver; When the ship unloader controls the trolley to move, the electromagnetic clutch receives a start signal through the wireless signal receiver, and the microcontroller controls the electromagnetic clutch to lock; When the ship unloader controls the trolley to brake, the electromagnetic clutch receives a disconnection signal through the wireless signal receiver, and the microcontroller controls the electromagnetic clutch to disconnect.

[0023] Optionally, a reduction shaft is rotatably connected to the trolley, the reduction shaft is arranged parallel to the second coupling shaft, a first transmission gear is coaxially fixed to the second coupling shaft, a second transmission gear is coaxially fixed to the reduction shaft, the first transmission gear is meshed with the second transmission gear, the size of the second transmission gear is larger than the size of the first transmission gear, the winch wheel is coaxially fixed to the reduction shaft, and when the trolley starts and moves from the track to the end of the track, the piston can just move from the starting position of energy storage in the energy storage sleeve to the ending position of energy storage.

[0024] By adopting the above technical solution, the number of revolutions of the winch wheel when the trolley completes a full stroke can be reduced, thereby appropriately reducing the length of the energy storage sleeve, thereby avoiding the situation where the second gear pump delivers too much lubricating oil due to the piston stroke being too long each time, and the first transmission gear and the second transmission gear form a deceleration, so that when atmospheric pressure acts on the piston, the piston can be reset stably and slowly, reducing the impact of the piston on the energy storage sleeve and improving the stability of the lubrication system.

[0025] In summary, the present application includes at least one of the following beneficial technical effects: 1. The driving member drives the first gear pump to extract the lubricating oil in the lubricating oil tank to the oil distributor. The oil distributor can adjust the grease injection amount of each lubrication point so that each lubrication point of the trolley can be fully lubricated and the grease injection time of each lubrication point is synchronized with the running time of the trolley, which can ensure that the grease injection amount of each point meets the operation requirements and avoid the waste caused by excessive grease injection into the lubrication point; 2. No additional power drive device is required, and the lubricating oil in the oil storage barrel can meet the lubrication needs for a long time, reducing the labor intensity of personnel; 3. The symmetrically arranged distributor design effectively reduces the length of the oil pipeline. Compared with arranging the pipeline from a single central location to each lubrication point, this symmetrical design reduces the intersection and branching of the pipeline, and reduces the complexity of pipeline installation and maintenance. In addition, the shorter pipeline path reduces the resistance to oil delivery and improves the efficiency of lubricant delivery; 4. When the trolley moves, the second gear pump is controlled by the linkage to pump more grease into the oil distribution tank each time it moves. When the trolley moves at a low frequency or a slow speed, the speed of the bidirectional gear pump will also be low, resulting in insufficient grease supply due to insufficient oil in the oil distribution tank. And such redundant design can prevent the other gear pump from continuing to supply oil when one gear pump is damaged, thereby further improving the lubrication effect and the stability of the lubrication system; 5. When the trolley is braking, the first coupling and the coupling are disconnected, and the energy storage component releases energy to drive the second gear pump to continue to operate independently, continuously supplying oil to the oil distribution tank, thereby ensuring that there is sufficient lubricating oil in the oil distribution tank and further improving the stability of the lubrication system.

DETAILED DESCRIPTION

[0032] The following is combined with Figure 1-5 This application is described in further detail.

[0033] Embodiment 1 of the present application discloses an automatic lubrication system for a trolley assembly for a bridge-type grab ship unloader.

[0034] like Figure 1 and Figure 2The automatic lubrication system of the trolley assembly for the bridge grab ship unloader includes two oil distributors 1, both of which are installed on the top of the trolley, and the two oil distributors 1 are symmetrically arranged about the center line of the length direction of the trolley, each of the oil distributors 1 has six oil outlets, and each of the oil outlets of the oil distributor 1 is connected to an oil pipe 11, and the six oil pipes 11 are respectively connected to the lubrication points of the two walking wheels 01, the two pulleys 02 and the two horizontal wheels 03 on the same side of the center line of the length direction of the trolley.

[0035] An oil distribution tank 2 is installed on one side of the top of the trolley, and the oil outlet end of the oil distribution tank 2 is connected to two oil pipes 11, and the two oil pipes 11 are respectively connected to the oil inlet ends of the two oil distributors 1. A first gear pump 3 is installed on the top of the trolley, and an oil storage tank 4 is installed on the top of the first gear pump 3, and the oil outlet end of the oil storage tank 4 is connected to the oil inlet end of the first gear pump 3.

[0036] A driving member 5 is commonly provided on the first gear pump 3 and the trolley traveling wheel 01 adjacent to the first gear pump 3. The driving member 5 comprises a first pulley 51 and a second pulley 52. ​​The first pulley 51 is coaxially fixed on the trolley traveling wheel 01, and the second pulley 52 is connected to the first gear pump 3. The first pulley 51 and the second pulley 52 are connected to each other through a first transmission belt 53. Both the first pulley 51 and the second pulley 52 are V-type pulleys, and the first transmission belt 53 is a V-type belt.

[0037] When the trolley moves, the traveling wheel 01 of the trolley rotates, and the traveling wheel 01 of the trolley drives the first pulley 51 to rotate. The first pulley 51 drives the second pulley 52 to rotate through the first transmission belt 53, thereby realizing the operation of the first gear pump 3, and realizing that the first gear pump 3 is synchronously started to supply oil while the trolley moves. The first gear pump 3 extracts the lubricating oil in the lubricating oil tank to the oil distributor 1. The oil distributor 1 can adjust the grease injection amount of each lubrication point, so that each lubrication point of the trolley can be fully lubricated, and the grease injection time of each lubrication point is synchronized with the running time of the trolley, that is, it can ensure that the grease injection amount of each point meets the operation requirements and can also avoid the waste caused by excessive grease injection into the lubrication point; There is no need to set up additional power drive devices, and the lubricating oil in the oil storage barrel can meet the lubrication needs for a long time, reducing the labor intensity of personnel; The oil distribution tank 2 can act as a buffer, making the oil pressure and flow in the lubrication system more stable. After the lubricating oil is delivered to the oil distribution tank 2, it is then supplied to the oil distributor 1 through the oil distribution tank 2. This setting can prevent the unstable lubricating oil supply caused by pressure fluctuations or uneven flow, thereby ensuring that each lubrication point obtains continuous and stable lubrication; At the same time, by symmetrically arranging the oil distributors 1 on both sides of the trolley, it can be ensured that the lubricating oil is evenly distributed to all parts that need lubrication. Each distributor is responsible for the lubrication of the parts on the corresponding side, avoiding the problem of uneven pressure or unbalanced distribution of lubricating oil that may be caused by a single distributor, thereby ensuring that each lubrication point is fully lubricated; The symmetrically arranged distributor design effectively reduces the length of the oil delivery pipe 11. Compared with arranging the pipeline from a single central position to each lubrication point, this symmetrical design reduces the intersection and branching of the pipeline, and reduces the complexity of pipeline installation and maintenance. In addition, the shorter pipeline path reduces the resistance to oil delivery and improves the efficiency of lubricant delivery.

The first transmission wheel 72 is coaxially fixed to the second coupling shaft 712, and the second gear pump 6 is connected to the second transmission wheel 73. The first transmission wheel 72 and the second transmission wheel 73 are connected to each other through a second transmission belt 74.

[0039] The connection assembly 8 includes an electromagnetic clutch 81, the stator of the electromagnetic clutch 81 is fixed on the first coupling shaft 711, the rotor of the electromagnetic clutch 81 is fixed on the second coupling shaft 712, the electromagnetic clutch 81 has a built-in battery module 82, a solar panel 83 for charging the battery module 82 is installed on the trolley, and a microcontroller 84 and a wireless signal receiver 85 are also provided on the electromagnetic clutch 81; When the ship unloader controls the trolley to move, the electromagnetic clutch 81 receives a start signal through the wireless signal receiver 85, and the microcontroller 84 controls the electromagnetic clutch 81 to lock; When the ship unloader controls the trolley to brake, the electromagnetic clutch 81 receives a disconnection signal through the wireless signal receiver 85, and the microcontroller 84 controls the electromagnetic clutch 81 to disconnect; The trolley is also provided with an energy storage component 9, which includes a reduction shaft 91, which is rotatably connected to the trolley, the reduction shaft 91 is arranged parallel to the second coupling shaft 712, a first transmission gear 92 is coaxially fixed on the second coupling shaft 712, a second transmission gear 93 is coaxially fixed on the reduction shaft 91, the gear of the second transmission gear 93 is larger than the size of the first transmission gear 92, a winch wheel 94 is coaxially fixed on the reduction shaft 91, an energy storage sleeve 95 is installed on the trolley, the energy storage sleeve 95 and the reduction shaft 91 are perpendicular to each other, a piston 96 is slidably sealed in the energy storage sleeve 95, a traction rope 97 is wound around the winch wheel 94, one end of the traction rope 97 is fixed on the winch wheel 94, and the other end of the traction rope 97 is connected to the piston 96, when the trolley starts to move from the track to the end of the track, the piston 96 can just move from the starting position of energy storage in the energy storage sleeve 95 to the ending position of energy storage.

[0040] When the trolley is moving, the electromagnetic clutch 81 is locked, the travel wheel 01, the first pulley 51, the first coupling shaft 711 and the second coupling shaft 712 rotate synchronously, the second coupling shaft 712 drives the first transmission wheel 72 to rotate, the first transmission wheel 72 drives the second transmission wheel 73 to rotate through the second transmission belt 74, and the second gear pump 6 is started, so that the second gear pump 6 and the first gear pump 3 simultaneously extract the oil in the oil storage tank 4 into the oil distribution tank 2; In addition, the second coupling shaft 712 drives the first transmission gear 92 to rotate, the first transmission gear 92 drives the second transmission gear 93 to rotate, the second transmission gear 93 drives the reduction shaft 91 to rotate, the reduction shaft 91 drives the winch wheel 94 to rotate, the winch wheel 94 is wound up, and the traction rope 97 pulls the piston 96 to move.

At this time, under the action of atmospheric pressure, the piston 96 is pushed into the energy storage sleeve 95, and the piston 96 pulls the traction rope 97 to drive the winch wheel 94 to unwind, and the winch wheel 94 drives the reduction shaft 91 to rotate, and the reduction shaft 91 drives the second transmission gear 93 to rotate, and the second transmission gear 93 drives the first transmission gear 92 to rotate, so that the first transmission gear 92 drives the second coupling shaft 712 to rotate alone, and controls the second gear pump 6 to extract oil into the oil distribution tank 2; Thereby, more grease can be extracted into the oil distribution tank 2 when the trolley is moving and braking, and the rotation speed of the bidirectional gear pump will be low when the trolley moves at a low frequency or a slow speed, and there is a situation where the oil tank in the oil distribution tank 2 is insufficient, resulting in insufficient grease supply; And such redundant design can prevent one gear pump from being damaged while the other gear pump can continue to supply oil, thereby further improving the lubrication effect and the stability of the lubrication system; Moreover, the design of the reduction shaft 91 can reduce the number of rotations of the winch wheel 94 when the trolley completes a full stroke, thereby appropriately reducing the length of the energy storage sleeve 95, thereby avoiding the situation where the piston 96 strokes too long each time, causing the second gear pump 6 to deliver too much lubricating oil, and the first transmission gear 92 and the second transmission gear 93 form a reduction gear, so that when atmospheric pressure acts on the piston 96, the piston 96 can be stably and slowly reset, reducing the impact of the piston 96 on the energy storage sleeve 95, and improving the stability of the lubrication system.
