Technical Field
[0001] This utility model relates to the field of transportation line technology, and in particular to a transfer elevator. Background Technology
[0002] In automated production lines, mobile lifting platforms are commonly used to transfer items between different devices. These mobile lifting platforms all have a lifting rack for carrying items. Most existing mobile lifting platforms are of fixed size, and their pallet-holding mechanisms cannot be stored, resulting in large equipment sizes. Furthermore, when not in operation, they are prone to collisions with other objects in the workshop, leading to damage. Utility Model Content
[0003] The purpose of this utility model is to provide a lifting platform for transfer, which aims to solve the technical problem that the mechanism for clamping the pallet in the prior art cannot be stored, resulting in a large size of the equipment.
[0004] To achieve the above objectives, this utility model provides a lifting platform for transfer, including a gantry frame and a platform. The gantry frame has a lifting position for raising and lowering the platform. Both sides of the gantry frame have clamping mechanisms and lifting parts for driving the platform. The clamping mechanism includes a rotary motor, a guide rail, and a conveyor belt. The rotary motor enables the guide rail to swing 90°. A slider is provided within the guide rail for connection with the conveyor belt. A pushing cylinder, a spring, and a first and second pushing blocks slidably connected within the slider are fixedly installed within the slider. The pushing cylinder is connected to the first pushing block, and one side of the second pushing block is connected to the spring, while the other side is connected to the conveyor belt. The first and second pushing blocks are in a pressing fit.
[0005] Preferably, the slider includes a mounting part and a guide part. The mounting part is used to mount the push cylinder. The guide part is provided with a first guide groove and a second guide groove that are perpendicular to each other. The first guide groove is slidably connected to the first push block, and the second guide groove is slidably connected to the second push block. The second guide groove is fixedly installed to one end of the spring on the side away from the conveyor belt.
[0006] Preferably, the second pusher has an inclined surface, which enables the first pusher to push the second pusher to move towards or away from the center of the platform.
[0007] Preferably, the first pusher block is provided with the inclined surface, and the two inclined surfaces are pressed together.
[0008] Preferably, the slider has a mounting groove on the side away from the guide rail that opens toward the center of the platform, the upper and lower ends of the conveyor roller of the conveyor belt are disposed on the upper and lower inner walls of the mounting groove, and the mounting groove is provided with a driving part for driving the conveyor roller.
[0009] Preferably, the two columns of the gantry frame are provided with baffles at a height corresponding to the clamping mechanism to block the pallet.
[0010] Preferably, each guide rail has at least two sets of sliders slidably connected within it, with a gap between adjacent sliders.
[0011] The above-mentioned technical solutions of the transfer elevator provided in this embodiment of the utility model have at least one of the following technical effects:
[0012] In use, the platform is raised to the top of the lifting position by the lifting unit. At this time, the top surface of the platform is flush with the top surface of the external conveyor line. The guide rail is driven by a rotary motor to swing to a horizontal position. The guide rail drives the slider to move towards the conveyor line. Finally, the slider drives the conveyor belt to both sides of the conveyor line. When the conveyor line brings the pallet, the cylinder pushes the first push block, which squeezes the second push block to push the conveyor belt towards the side of the pallet and into contact. The two sides of the pallet are clamped by the two conveyor belts. Then the conveyor belt is started to transport the pallet onto the platform. After the pallet enters the platform, the lifting unit lowers the platform so that the top surface of the pallet at the top of the platform is flush with the top surface of the conveyor line, ready to stack the next pallet. This cycle continues until the platform is lowered to the bottom of the lifting position, and then the pallet stack is transferred. In the non-use state, the guide rail is driven by a rotary motor to swing to a vertical position, which reduces the size of the equipment, makes it easier to store, and avoids collisions with other objects that could damage the equipment.

For example, they can refer to a fixed connection, a detachable connection, or an integral part; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium; they can refer to the internal communication of two components or the interaction between two components. Those skilled in the art can understand the specific meaning of the above terms in this embodiment of the invention according to the specific circumstances.
[0024] In one embodiment of this utility model, such as Figures 1-5As shown, a transfer lift is provided, including a gantry frame 1 and a platform 11. The gantry frame 1 is provided with a lifting position for lifting the platform 11. Both sides of the gantry frame 1 are provided with a clamping mechanism 2 and a lifting part 10 for driving the platform 11. The clamping mechanism 2 includes a rotary motor 21, a guide rail 22 and a conveyor belt 23. The rotary motor 21 is used to enable the guide rail 22 to swing 90°. A slider 3 is provided in the guide rail 22 for connecting with the conveyor belt 23. A push cylinder 30, a spring 301 and a first push block 31 and a second push block 32 are fixedly installed in the slider 3. The push cylinder 30 is connected to the first push block 31. One side of the second push block 32 is connected to the spring 301 and the other side is connected to the conveyor belt 23. The first push block 31 and the second push block 32 are in a pressing fit.
[0025] Furthermore, the slider 3 includes a mounting portion 302 and a guide portion 303. The mounting portion 302 is used to mount the push cylinder 30. The guide portion 303 is provided with a first guide groove 33 and a second guide groove 34 that are perpendicular to each other. The first guide groove 33 is slidably connected to the first push block 31, and the second guide groove 34 is slidably connected to the second push block 32. The second guide groove 34 is fixedly installed to one end of the spring 301 on the side away from the conveyor belt 23. The second push block is provided with an inclined surface, which is used to enable the first push block to push the second push block to move towards or away from the center of the platform 11. The first push block is provided with the inclined surface, and the two inclined surfaces are pressed together. Specifically, during use, the cylinder 30 pushes the first push block 31 to slide in the first guide groove 33 and squeeze the second push block 32. The second push block 32 pushes the conveyor belt to move closer to the platform 11, while the second push block 32 stretches the spring 301. After operation stops, the cylinder 30 drives the first push block 31 to slide in the first guide groove 33. Under the elastic contraction of the spring 301, the second push block 32 is pulled away from the platform 11, thus achieving the effect of recycling the conveyor belt 23.
[0026] Furthermore, the slider 3 has a mounting groove 4 on the side away from the guide rail 22, opening towards the center of the platform 11. The upper and lower ends of the conveyor roller of the conveyor belt 23 are disposed on the upper and lower inner walls of the mounting groove 4. The mounting groove 4 is provided with a drive unit for driving the conveyor roller. Specifically, by setting the mounting groove 4, the connection between the conveyor belt 23 and the second push block 32 can be better achieved. At the same time, the drive unit can be better installed on the mounting groove 4 so that the drive unit can drive the conveyor belt 23. In addition, the drive unit is a motor. The main body of the motor is installed on the mounting groove 4, and the output shaft of the motor passes through the mounting groove 4 and is connected to the conveyor roller of the conveyor belt 23 to achieve the driving effect.
[0027] Furthermore, the two columns of the gantry frame 1 are equipped with baffles 12 at a height corresponding to the clamping mechanism 2 to block the pallets. Specifically, the pallets on the transport line are conveyed towards the center of the platform 11 by the conveyor belt 23, so that one side of the pallet contacts the baffle 12, thereby achieving the effect of fixing the pallet stacking.
[0028] Furthermore, each guide rail 22 has at least two sets of sliders 3 slidably connected within it, with a gap between adjacent sliders 3. Specifically, by setting multiple sets of sliders 3 to maintain the balance of the guide rail 22 after installation, the conveyor belt 23 remains horizontal after extending out of the guide rail 22, achieving better performance.
[0029] Working principle: During use, the lifting unit 10 raises the platform 11 to the top of the lifting position. At this time, the top surface of the platform 11 is flush with the top surface of the external conveyor line. The rotary motor 21 drives the guide rail 22 to swing to a horizontal position. The guide rail 22 drives the slider 3 to move towards the conveyor line. Finally, the slider 3 drives the conveyor belt 23 to reach both sides of the conveyor line. When the conveyor line brings the pallet, the push cylinder 30 pushes the first push block 31, causing the first push block 31 to squeeze the second push block 32, so that the slider 3 pushes the conveyor belt 23 to approach and contact the side of the pallet. The pallet is held between two conveyor belts 23 on both sides. The conveyor belts 23 are then started to transport the pallet onto the platform 11. After the pallet enters the platform 11, the lifting unit 10 lowers the platform 11 so that the top surface of the pallet at the top of the platform 11 is flush with the top surface of the transport line, ready to stack the next pallet. This cycle continues until the platform 11 is lowered to the bottom of the lifting position, and then the pallet stack is transferred. In the non-use state, the guide rail 22 is driven by the rotary motor 21 to swing to the vertical position, which reduces the size of the equipment, makes it easy to store, and avoids collisions with other objects that could damage the equipment.

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.
