Description

Technical Field

[0001] This application relates to the field of railway transportation. Specifically, it relates to a cargo loading and unloading device suitable for railway transportation. Background Art

[0002] Activities that change the storage and support state of objects within the same geographical area, such as within a station, a factory, or a warehouse, are called loading and unloading. Sometimes, in specific situations, simply referring to loading or simply referring to handling also encompasses the complete meaning of loading and handling. In common usage, in the logistics field such as railway transportation, the overall activity of loading and handling is often referred to as cargo loading and unloading.

[0003] In the prior art, during the process of the crane clamping and transporting goods, if the pressure borne by the rotating rod for clamping the goods is too large, it may cause the mechanical structure of the rotating rod to be overloaded, resulting in problems such as deformation, cracks, or fractures. If the rotating rod bears too much pressure, it may cause instantaneous fracture or local damage, leading to the failure of the clamping device, resulting in the dropping of goods, equipment damage, or potential safety hazards for operators. Summary of the Invention

[0004] Aiming at the deficiencies of the prior art, the present invention provides a cargo loading and unloading device suitable for railway transportation, which solves the problems raised in the above background art.

[0005] To achieve the above object, the present application provides a cargo loading and unloading device suitable for railway transportation, including a fixing plate. A suspension rod is fixedly connected to the back of the fixing plate, and a crane is assembled at the bottom of the suspension rod; A hydraulic component is assembled on the front of the fixing plate. A plug rod is assembled on the front of the hydraulic component. A slide rail is assembled on the side of the fixing plate. A first rack is slidably connected to the outer wall of the slide rail. A rotating rod is rotatably connected to the front of the fixing plate through a bearing. A gear plate is fixedly sleeved on the outer wall of the rotating rod. A clamping jaw is assembled on the front of the gear plate. The first rack meshes with the gear plate. An electric telescopic rod is fixedly connected to the top of the fixing plate. A connecting rod is fixedly connected to the top of the electric telescopic rod. The end of the connecting rod away from the electric telescopic rod is fixedly connected to the back of the first rack. A lubricating device for lubricating the plug rod is assembled on the front of the fixing plate. An anti-slip device for improving the anti-slip performance of the goods is assembled inside the clamping jaw.

[0006] Preferably, the hydraulic component includes a first hydraulic chamber fixedly connected to the front of the fixing plate. A first hydraulic rod is slidably connected to one end of the piston inside the first hydraulic chamber. A first spring is movably sleeved on the outer wall of the first hydraulic rod. A second hydraulic rod is slidably connected to one end of the piston inside the first hydraulic chamber. The second hydraulic rod is fixedly connected to the front of the plug rod.

[0007] Preferably, two sliding grooves for the insertion rod are formed on the front surface of the gear plate. A stop block is fixedly connected to the bottom of the first hydraulic rod, and two ends of the first spring are respectively fixedly connected to the bottom of the first hydraulic chamber and the top of the stop block.

[0008] Preferably, the lubricating device includes a support plate fixedly connected to the front surface of the fixed plate. An oil tank is fixedly connected to the top of the support plate, and a peristaltic pump body is fixedly connected to the top of the support plate.

[0009] Preferably, a suction pipe is assembled on the side of the peristaltic pump body, and one end of the suction pipe far from the peristaltic pump body is fixedly connected to the side of the oil tank. A fuel injection pipe is assembled on the side of the peristaltic pump body.

[0010] Preferably, a second hydraulic chamber is fixedly connected to the top of the support plate. The second hydraulic chamber is fixedly connected to the side of the first hydraulic chamber and is internally communicated. A second rack is slidably connected to one end of the second hydraulic chamber by a piston. A circular gear is fixedly sleeved on the outer wall of the output end of the peristaltic pump body, and the second rack meshes with the circular gear.

[0011] Preferably, the anti-slip device includes a third hydraulic chamber fixedly connected to the top of the support plate. A third hydraulic rod is slidably connected to one end of the third hydraulic chamber. A fixing rod is assembled on the side of the third hydraulic rod, and the fixing rod is fixedly connected to the back of the second rack. A fourth hydraulic chamber is fixedly connected to the front surface of the inner wall of the clamping jaw. A fourth hydraulic rod is slidably connected to one end of the fourth hydraulic chamber by a piston. A second spring is fixedly connected to the top of the fourth hydraulic rod, and an anti-slip block is fixedly connected to the top of the second spring.

[0012] Preferably, a connecting hose is assembled on the side of the third hydraulic chamber, and one end of the connecting hose far from the third hydraulic chamber is fixedly connected to the side of the fourth hydraulic chamber.

[0013] The beneficial effects of the present application are as follows: 1. When the fixed plate is lowered by the suspension rod in the present application, the first hydraulic rod touches the ground and is squeezed, resulting in an increase in the pressure inside the first hydraulic chamber. This pressure change drives the second hydraulic rod to move forward, and then the insertion rod moves backward to release the locking of the gear plate. When the fixed plate rises, the first hydraulic rod is no longer squeezed by the ground, and the first spring drives the hydraulic rod to reset. The pressure inside the hydraulic chamber decreases, the second hydraulic rod moves forward, and the insertion rod is inserted into the sliding groove of the gear plate again to lock the gear plate.

[0014] Second, when the internal pressure of the first hydraulic chamber increases, the second hydraulic rod moves forward, and at the same time, the second rack also moves to the left. The movement of the second rack drives the circular gear to rotate, thereby driving the output end of the peristaltic pump to rotate. After the peristaltic pump body is started, it sucks lubricating oil from the lubricating oil tank through the suction pipe and sprays the lubricating oil onto the outer wall of the insertion rod through the spray pipe, realizing automatic lubrication of the insertion rod, reducing the friction between the insertion rod and the clamping jaw, and extending the service life of the equipment.

[0015] Third, when the second rack moves to the left, it drives the third hydraulic rod to move to the left through the fixed rod, increasing the internal pressure of the third hydraulic chamber and the connecting hose, and pushing the fourth hydraulic rod to rise. When the fourth hydraulic rod rises, it drives the anti-sliding block to rise through the second spring to fix the hook at the top of the goods. When the hook presses on the anti-sliding block, the elastic effect of the second spring ensures that the anti-sliding block can adapt to the pressure of the hook without affecting the rise of the fourth hydraulic rod. The telescopic function of the anti-sliding block can be dynamically adjusted according to the shape and size of the goods to ensure closer contact between the clamping jaw and the goods during the grasping process.

[0024] See Figures 1-6 , this embodiment provides a cargo handling device applicable to railway transportation, including a fixing plate 1, a suspension rod 5 fixedly connected to the back of the fixing plate 1, and a crane 6 assembled at the bottom of the suspension rod 5; The front of the fixed plate 1 is assembled with a hydraulic component. The front of the hydraulic component is assembled with a plug rod 25. The side of the fixed plate 1 is assembled with a slide rail 210. The outer wall of the slide rail 210 is slidably connected with a first rack 29. The front of the fixed plate 1 is rotatably connected with a rotating rod 26 through a bearing. A gear plate 27 is fixedly sleeved on the outer wall of the rotating rod 26. The front of the gear plate 27 is assembled with a clamping jaw 28. The first rack 29 meshes with the gear plate 27. The top of the fixed plate 1 is fixedly connected with an electric telescopic rod 211. The top of the electric telescopic rod 211 is fixedly connected with a connecting rod 212. One end of the connecting rod 212 away from the electric telescopic rod 211 is fixedly connected to the back of the first rack 29. The front of the fixed plate 1 is assembled with a lubricating device 3 for lubricating the plug rod 25. The inside of the clamping jaw 28 is assembled with an anti-slip device 4 for improving the anti-slip of the goods. Through the combination of components such as the hydraulic component, the slide rail 210, the first rack 29, the gear plate 27, and the clamping jaw 28, the functions of clamping, moving, and loading and unloading the goods are realized. The core lies in realizing the flexible movement of the clamping jaw 28 through hydraulic and mechanical transmission, and improving the reliability and safety of the equipment through the lubricating device 3 and the anti-slip device 4. The hydraulic component includes a first hydraulic chamber 21. The first hydraulic chamber 21 is fixedly connected to the front of the fixed plate 1. One end of the piston inside the first hydraulic chamber 21 is slidably connected with a first hydraulic rod 22. A first spring 23 is movably sleeved on the outer wall of the first hydraulic rod 22. One end of the piston inside the first hydraulic chamber 21 is slidably connected with a second hydraulic rod 24. The second hydraulic rod 24 is fixedly connected to the front of the plug rod 25. The first hydraulic rod 22 and the second hydraulic rod 24 are telescopic through the piston movement in the first hydraulic chamber 21, providing power for the plug rod 25 to enable it to insert into or withdraw from the jack of the gear plate 27. Two chutes for the plug rod 25 to slide are opened on the front of the gear plate 27. A stop block is fixedly connected to the bottom of the first hydraulic rod 22. Two ends of the first spring 23 are respectively fixedly connected to the bottom of the first hydraulic chamber 21 and the top of the stop block. The chutes on the gear plate 27 allow the plug rod 25 to fix the clamping jaw 28, ensuring that when the clamping jaw 28 clamps the goods, the rotating rod 26 of the gear plate 27 does not break. The stop block is fixed to the bottom of the first hydraulic rod 22, and the first spring 23 is connected between the bottom of the first hydraulic chamber 21 and the top of the stop block, ensuring the stable movement of the first hydraulic rod 22.

[0025] When the above-mentioned device is in specific use, the crane 6 lowers the fixed plate 1 through the boom 5. The fixed plate 1 drives the first hydraulic chamber 21 to descend, and the first hydraulic chamber 21 drives the first hydraulic rod 22 to descend. When the first hydraulic rod 22 touches the ground, the first hydraulic rod 22 is squeezed. When the first hydraulic rod 22 is squeezed, the internal pressure of the first hydraulic chamber 21 increases, driving the second hydraulic rod 24 to move forward. The second hydraulic rod 24 drives the insertion rod 25 to move backward, unlocking the gear plate 27. Then, the electric telescopic rod 211 is started. The electric telescopic rod 211 drives the connecting rod 212 to descend, and the connecting rod 212 drives the first rack 29 to descend. The first rack 29 slides on the outer wall of the slide rail 210. The descent of the first rack 29 drives the gear plate 27 to rotate, and the gear plate 27 drives the jaw 28 to rotate counterclockwise. The two jaws 28 clamp the hook at the top of the goods. Then, the boom 5 is started to drive the fixed plate 1 to rise. When the fixed plate 1 rises, it drives the first hydraulic chamber 21 to rise. The rise of the first hydraulic chamber 21 causes the first hydraulic rod 22 to no longer be squeezed by the floor. The first spring 23 drives the first hydraulic rod 22 to reset. The internal pressure of the first hydraulic chamber 21 decreases, driving the second hydraulic rod 24 to move forward. The second hydraulic rod 24 drives the insertion rod 25 to insert into the chute of the gear plate 27, realizing the locking of the gear plate 27. Embodiment

[0026] See Figures 3-4 , on the basis of Embodiment 1, the lubrication device 3 includes a support plate 31. The support plate 31 is fixedly connected to the front of the fixed plate 1. A lubricating oil tank 32 is fixedly connected to the top of the support plate 31, and a peristaltic pump body 33 is fixedly connected to the top of the support plate 31. Through the lubricating oil tank 32 and the peristaltic pump body 33, lubricating oil can be delivered to the parts that need lubrication, reducing the friction between the insertion rod 25 and the gear plate 27 and extending the service life of the device. The lubrication device 3 is integrated on the fixed plate 1, with a compact design, facilitating maintenance and operation. A suction pipe 34 is assembled on the side of the peristaltic pump body 33, and the end of the suction pipe 34 far from the peristaltic pump body 33 is fixedly connected to the side of the lubricating oil tank 32. A spray oil pipe 35 is assembled on the side of the peristaltic pump body 33. The suction pipe 34 extracts the lubricating oil from the lubricating oil tank 32, and the spray oil pipe 35 sprays the lubricating oil onto the surface of the insertion rod to achieve the lubrication function. The use of the peristaltic pump body 33 realizes the automatic delivery of lubricating oil, reducing the frequency of manual maintenance. A second hydraulic chamber 37 is fixedly connected to the top of the support plate 31. The second hydraulic chamber 37 is fixedly connected to the side of the first hydraulic chamber 21 and is internally connected.

Through the movement of the second hydraulic chamber 37 and the second rack 38, the circular gear 36 is driven to rotate, thereby realizing the automatic operation of the peristaltic pump body 33. The operation of the lubrication device 3 is linked with the hydraulic components to ensure that the peristaltic pump is automatically started when lubrication is required.

[0027] When the above-mentioned device is in specific use, when the pressure inside the first hydraulic chamber 21 increases and drives the second hydraulic rod 24 to move forward, it also drives the second rack 38 to move to the left. The second rack 38 drives the circular gear 36 to rotate, and the circular gear 36 drives the output end of the peristaltic pump body 33 to rotate. After the peristaltic pump body 33 is started, it drives the suction pipe 34 to suck lubricating oil from the lubricating oil tank 32 and spray it through the spray oil pipe 35 to spray lubricating oil on the outer wall of the insertion rod 25, improving the service life of the insertion rod 25. Embodiment

[0028] See Figures 1-7 , on the basis of Embodiment 1, the anti-slip device 4 includes a third hydraulic chamber 42, which is fixedly connected to the top of the support plate 31.

The top of the fourth hydraulic rod 46 is fixedly connected with a second spring 47, and the top of the second spring 47 is fixedly connected with an anti-slip block 48. Through the cooperation of the third hydraulic chamber, the third hydraulic rod 43, the fourth hydraulic chamber 45, and the fourth hydraulic rod 46, the anti-slip block 48 can automatically expand and contract according to the shape and size of the goods, improving the stability of grasping. At the same time, the second spring 47 also has buffering function, reducing the shaking of the goods during grasping and hoisting, and protecting the goods and the device. A connecting hose 41 is assembled on the side of the third hydraulic chamber 42. One end of the connecting hose 41 away from the third hydraulic chamber 42 is fixedly connected to the side of the fourth hydraulic chamber 45. The third hydraulic chamber 42 and the fourth hydraulic chamber 45 are connected through the connecting hose 41 to realize the coordinated operation of the hydraulic system, ensuring that the expansion and contraction action of the anti-slip block 48 is synchronized with the movement of the jaw.

[0029] When the above-mentioned device is in specific use, when the second rack 38 moves to the left, it drives the fixing rod 44 to move to the left. The fixing rod 44 drives the third hydraulic rod 43 to move to the left. When the third hydraulic rod 43 moves, the pressure inside the third hydraulic chamber 42, the connecting hose 41 increases, driving the fourth hydraulic rod 46 to rise. When the fourth hydraulic rod 46 rises, it drives the second spring 47 to rise. The second spring 47 drives the anti-slip block 48 to rise to fix the hook on the top of the goods. When the anti-slip block 48 pressed by the hook enables the second spring 47 to be elastic, it will not affect the rise of the fourth hydraulic rod 46.
