Description

Technical Field

[0001] This utility model relates to the field of transportation equipment technology, and in particular to a large-scale work platform transfer device. Background Technology

[0002] In factory workshops, industrial production equipment is often large in size and weight. During production line modifications and adjustments, this equipment needs to be moved, typically using large mobile cranes and trucks. However, this method is limited by factory space, and problems such as collisions and difficulties in positioning the equipment can easily occur during hoisting. Furthermore, the stability of hoisting is not high during the replacement and disassembly of large components, posing a certain degree of danger. To address this issue, Chinese patent application CN208150877U discloses a transfer device for repairing large equipment parts. This device includes a plate with wheels, on which jacks are mounted. A support plate is installed on the jacks, supporting the replacement parts. The jacks raise the support plate to the appropriate height for parts replacement, facilitating the changeover. The wheels on the plate allow for easy transfer of the parts.

[0003] Based on the existing technologies mentioned above, ropes are currently commonly used to secure transfer equipment. However, rope securing requires manual operation, the transfer platform is off the ground, and there is a risk of falls for personnel during operation. Furthermore, securing goods with ropes is cumbersome, time-consuming, and labor-intensive. Utility Model Content

[0004] The purpose of this invention is to solve the problem of cumbersome and dangerous fixed operations during the transfer of large equipment in the prior art.

[0005] To achieve the above objectives, the present invention adopts the following technical solution:

[0006] A large-scale work platform transfer device includes a frame with wheels, a plurality of hydraulic cylinders inside the frame, a mounting platform on the piston rod of each hydraulic cylinder, a triggering device below the mounting platform, the triggering device being located on the frame, a base on the triggering device, the bases being symmetrically arranged on the frame, a lifting rod inside the base, a roller at the bottom of the lifting rod being connected to the triggering device, the lifting rod being slidably connected to the base, a mounting plate on the lifting rod, a gripper on the mounting plate, the gripper being hinged to the mounting plate, a cylinder on the gripper, the piston rod of the cylinder being hinged to the gripper, and the cylinder being hinged to the mounting plate.

[0007] Preferably, the triggering device includes a cylinder body, a sliding cavity provided inside the cylinder body, the sliding cavity being a three-way type, a trigger plate provided on the sliding cavity, a first sliding rod provided at the bottom of the trigger plate, the first sliding rod being slidably connected to the sliding cavity, a second sliding rod symmetrically provided inside the sliding cavity, the second sliding rod being slidably connected to the sliding cavity, a spring sleeved on the second sliding rod, the spring being located inside the sliding cavity, a lifting block provided on the second sliding rod, the lifting block having a trapezoidal cross-section, the inclined surface of the lifting block being slidably connected to the roller.

[0008] Preferably, the mounting plate has a guide rod at its bottom, and the guide rod is slidably connected to the base.

[0009] Preferably, the gripper includes a lower gripper plate and an upper gripper plate, the lower gripper plate is hinged to the mounting plate, the upper gripper plate is hinged to the lower gripper plate, a torsion spring is provided between the upper gripper plate and the lower gripper plate, and the lower gripper plate is hinged to the piston rod of the cylinder.

[0010] Preferably, rubber pads are provided on the clamping surfaces of the upper clamping plate and the lower clamping plate.

[0011] Preferably, the base includes a bracket located on the frame, a cylinder is provided on the bracket, a lifting rod passes through the cylinder and is slidably connected to the cylinder, and an output port is provided on the cylinder and connected to the air inlet of the cylinder.

[0012] The beneficial effects proposed by this utility model are as follows:

[0013] The operator moves the frame under the goods to be transferred. Driven by an external oil pump, the piston rod of the hydraulic cylinder extends upward, moving the mounting platform closer to the goods. Once the mounting platform contacts and supports the goods, the piston rod retracts downward, lowering the mounting platform and gradually moving it closer to the triggering device. When the goods reach and fit against the triggering device, the triggering device activates. The triggering device, through the rollers, lifts the lifting rod upward, which moves the mounting plate upward towards the goods. Simultaneously, the grippers, under the action of the mounting plate, finally fit against the goods. After the grippers fit against the goods, the piston rod of the cylinder extends, clamping and securing the goods, completing the fixed clamping during goods transfer and achieving automatic fixed clamping. Conversely, when the goods are removed, the piston rod of the hydraulic cylinder simply lifts the mounting platform upward. As the goods gradually reduce the triggering pressure on the triggering device, the grippers release their clamping force. It enables automatic clamping and contact of goods, improves the efficiency of cargo transfer, and reduces the risk of accidents when operators climb heights to use ropes to secure goods.

[0022] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments.

[0023] Reference Figures 1 to 7This utility model discloses a large-scale work platform transfer device, comprising a frame 1 with wheels, a plurality of hydraulic cylinders 2 inside the frame 1, a mounting platform on the piston rod of each hydraulic cylinder 2, a triggering device below the mounting platform, the triggering device being located on the frame 1, a base 3 on the triggering device, the base 3 being symmetrically arranged on the frame 1, a lifting rod 4 inside the base 3, a roller 5 at the bottom of the lifting rod 4, the roller 5 being connected to the triggering device, the lifting rod 4 being slidably connected to the base 3, a mounting plate 6 on the lifting rod 4, a gripper on the mounting plate 6, the gripper being hinged to the mounting plate 6, a cylinder 7 on the gripper, the piston rod of the cylinder 7 being hinged to the gripper, and the cylinder 7 being hinged to the mounting plate 6.

[0024] Specifically, the operator moves the frame 1 under the goods to be transferred. Driven by an external oil pump, the piston rod of the hydraulic cylinder 2 extends upward, causing the mounting platform to move closer to the goods. Once the mounting platform contacts and supports the goods, the piston rod of the hydraulic cylinder 2 moves downward and retracts, causing the mounting platform to descend and gradually approach the triggering device. When the goods descend to the triggering device and come into contact with it, the triggering device is activated. The triggering device, through the roller 5, lifts the lifting rod 4 upward. The lifting rod 4 moves the mounting plate 6 upward and closer to the goods. Simultaneously, the grippers, under the action of the mounting plate 6, finally come into contact with the goods. After the grippers come into contact with the goods, the piston rod of the cylinder 7 extends to clamp and fix the goods in place, completing the fixed clamping of the goods during transfer and achieving automatic fixed clamping during the transfer process. Conversely, when the goods are removed, the piston rod of the hydraulic cylinder 2 simply lifts the mounting platform upward. As the goods gradually reduce the triggering pressure on the triggering device, the grippers release their clamping force on the goods. It enables automatic clamping and contact of goods, improves the efficiency of cargo transfer, and reduces the risk of accidents when operators climb heights to use ropes to secure goods.

[0025] Specifically, the triggering device includes a cylinder body 8, a sliding cavity 23 inside the cylinder body 8, the sliding cavity 23 being a three-way type, a trigger plate 9 on the sliding cavity 23, a first sliding rod 10 at the bottom of the trigger plate 9, the first sliding rod 10 being slidably connected to the sliding cavity 23, a second sliding rod 12 symmetrically arranged inside the sliding cavity 23, the second sliding rod 12 being slidably connected to the sliding cavity 23, a spring 11 sleeved on the second sliding rod 12, the spring 11 being located inside the sliding cavity 23, a lifting block 13 on the second sliding rod 12, the lifting block 13 having a trapezoidal cross-section, and the inclined surface of the lifting block 13 being slidably connected to the roller 5. The sliding cavity 23 is filled with liquid. The first sliding rod 10 and the second sliding rod 12 are piston rod structures. When the cargo applies pressure to the trigger plate 9, the trigger plate 9 moves downward under the sliding action of the first sliding rod 10. The first sliding rod 10 pushes the liquid in the sliding cavity 23. The liquid is pressured by the first sliding rod 10 and flows in the direction of the second sliding rod 12 in the sliding cavity 23, transmitting the pressure received by the first sliding rod 10 to the second sliding rod 12. At this time, the second sliding rod 12 extends outward from the cylinder 8, driving the lifting block 13 to slide in a sliding connection with the roller 5, realizing the lifting rod 4 sliding up and down. Since the cross-section of the lifting block 13 is trapezoidal, when the second sliding rod 12 extends outward, the lifting rod 4 slides upward. Conversely, when the cargo is unloaded, the loading platform gradually lifts the cargo. At this time, the pressure received on the trigger plate 9 gradually decreases, and the liquid thrust received by the second slide rod 12 also gradually decreases. The spring 11 is sleeved on the second slide rod 12, and one end of the spring 11 abuts against the inner wall of the slide cavity 23. Through the elastic force of the spring 11, the second slide rod 12 pushes the liquid towards the first slide rod 10. At this time, the liquid generates a thrust on the first slide rod 10, causing the trigger plate 9 to rise until the trigger plate 9 separates from the cargo, completing the reset of the trigger plate 9. This realizes an automatic operation structure that uses the pressure of the cargo to trigger the mounting plate 6 to drive the gripper to rise and fall.

[0026] Specifically, the mounting plate 6 is provided with guide rods 14 at its bottom, and the guide rods 14 are slidably connected to the base 3. During the lifting and lowering process of the mounting plate 6, the lifting rod 4 alone cannot keep the mounting plate 6 in a balanced state. During the lifting and lowering process, the mounting plate 6 will rotate and deviate about the lifting rod 4 as the axis. The guide rods 14 are evenly distributed at the bottom of the mounting plate 6, which can limit the circumferential rotation of the mounting plate 6 and improve the stability of the lifting and lowering process of the mounting plate 6.

[0027] Specifically, the gripper includes a lower clamping plate 15 and an upper clamping plate 16. The lower clamping plate 15 is hinged to the mounting plate 6, and the upper clamping plate 16 is hinged to the lower clamping plate 15. A torsion spring 17 is provided between the upper clamping plate 16 and the lower clamping plate 15. The lower clamping plate 15 is hinged to the piston rod of the cylinder 7. During the gripping process, the piston rod of the cylinder 7 extends, pushing the lower clamping plate 15 to rotate relative to the mounting plate 6 and move towards the cargo until it is pressed against the cargo. Simultaneously, the upper clamping plate 16 is driven by the lower clamping plate 15 to press against the cargo. During this process, due to the irregular surface of the cargo, differences in the gripping contact surface are formed. At this time, the upper clamping plate 16 forms an angle with the lower clamping plate 15 under the action of the torsion spring 17, so that the gripper can adapt to the irregular surface of the cargo and maintain stable gripping force.

[0028] Specifically, rubber pads 18 are provided on the clamping surfaces of the upper clamping plate 16 and the lower clamping plate 15. The rubber pads 18 are used to separate the jaws from the goods. Through the rubber pads 18, the surface wear of the goods caused by friction during the clamping process can be reduced. Since rubber has elasticity and plasticity, it can adapt to goods with irregular surfaces, increase the contact area between the jaws and the goods during clamping, and improve the stability of clamping the goods.

[0029] Specifically, the base 3 includes a bracket 19 located on the frame 1. A cylinder 20 is mounted on the bracket 19, and a lifting rod 4 passes through the cylinder 20, slidably connected to it. An output port 21 is provided on the cylinder 20, connected to the air inlet of the cylinder 7. Gas is stored in the cylinder 20. When the lifting rod 4 rises, it compresses the gas inside the cylinder 20. The gas is then input into the cylinder 7 through the output port 21, providing clamping force for the lower gripper and achieving automatic clamping. This also reduces the need for external air sources and simplifies the equipment structure.

[0030] The above description is only a preferred embodiment of the present utility model, but the protection scope of the present utility model is not limited thereto. Any equivalent substitutions or changes made by those skilled in the art within the technical scope disclosed in the present utility model, based on the technical solution and the inventive concept of the present utility model, should be included within the protection scope of the present utility model.
