[0046] In the following description, only certain exemplary embodiments are briefly described. As those skilled in the art will recognize, the described embodiments can be modified in various ways without departing from the spirit or scope of this application. Therefore, the drawings and description are considered to be exemplary in nature and not restrictive.

[0047] See Figures 1-4 This invention illustrates a preferred embodiment of a lifting device with a function for storing casters. The lifting device with the function for storing casters is used for lifting electromechanical equipment and includes:

[0048] Base 1, base 1 has a receiving cavity 11;

[0049] Lifting plate 2 is provided in the storage cavity 11 and can be moved up and down.

[0050] The caster wheel 3 is movably mounted on the lifting plate 2. The caster wheel 3 has a first state and a second state. In the first state, the caster wheel 3 is located inside the storage cavity 11, so that the caster wheel 3 is separated from the ground while the bottom surface of the base 1 can contact the ground. In the second state, the caster wheel 3 is located outside the base 1, so that the caster wheel 3 is in contact with the ground while the bottom surface of the base 1 is separated from the ground.

[0051] The first lifting drive mechanism 4 is mounted on the base 1. The output end of the first lifting drive mechanism 4 is connected to the lifting plate 2, and the lifting plate 2 can move up and down with the output end of the first lifting drive mechanism 4.

[0052] The lifting device of this utility model has a storage cavity 11 on the base 1, a lifting plate 2 that can be moved up and down in the storage cavity 11, casters 3 that can be movably mounted on the lifting plate 2, and the output end of the first lifting drive mechanism 4 connected to the lifting plate 2. When the lifting device needs to be moved, the casters 3 are kept in a second state, that is, the casters 3 are located outside the base 1, so that the casters 3 are in contact with the ground and the bottom surface of the base 1 is separated from the ground, making it convenient to move the lifting device. When the lifting device does not need to be moved, the lifting plate 2 is driven upward by the first lifting drive mechanism 4 until the casters 3 are housed in the storage cavity 11, that is, the casters 3 are switched to the first state, so that the casters 3 are separated from the ground and the bottom surface of the base 1 is in contact with the ground. This can effectively prevent the lifting device from shaking during the lifting of electromechanical equipment, resulting in higher stability, facilitating stable lifting of electromechanical equipment, and making the installation of electromechanical equipment more convenient.

[0053] See Figure 2 and Figure 3 In one embodiment, the lifting device with the function of accommodating casters further includes:

[0054] The first guide mechanism 5 connects the base 1 and the lifting plate 2. The first guide mechanism 5 is used to guide the movement of the lifting plate 2, so that the lifting plate 2 moves up and down more smoothly and stably.

[0055] See Figure 2 and Figure 3 In one embodiment, the first guide mechanism 5 includes:

[0056] Movable sleeve 51, the lower end of movable sleeve 51 is connected to lifting plate 2, and the upper end of movable sleeve 51 extends toward the top wall of storage cavity 11; and

[0057] The guide rod 52 has its lower end movably inserted into the center hole of the movable sleeve 51, and its upper end connected to the top wall of the receiving cavity 11, i.e., the guide rod 52 is connected to the base 1. Thus, when the lifting plate 2 moves upward under the drive of the first lifting mechanism 4, the movable sleeve 51 moves upward along the guide rod 52. Conversely, when the lifting plate 2 moves downward under the drive of the first lifting mechanism 4, the movable sleeve 51 moves downward along the guide rod 52, providing excellent guiding function. This design is simple, practical, and low-cost, reducing the cost of the lifting device.

[0058] See Figures 2-3 In one embodiment, there are two sets of first guide mechanisms 5, which are arranged at intervals along the length of the lifting plate 2 to make the movement of the lifting plate 2 smoother and more stable.

[0059] Of course, in other embodiments, the first guide mechanism 5 may include:

[0060] Guide rail, the guide rail is mounted on the base 1 and extends along the moving direction of the lifting plate 2; and

[0061] The slider is movably mounted on the guide rail and connected to the lifting plate 2. Thus, when the lifting plate 2 is driven upward by the first lifting drive mechanism 4, the slider moves upward along the guide rail. When the lifting plate 2 is driven downward by the first lifting drive mechanism 4, the slider moves downward along the guide rail, thus achieving the same effect of guiding the movement of the lifting plate 2.

[0062] See Figures 1-3 In one embodiment, the first lifting drive mechanism 4 includes:

[0063] First driver 41;

[0064] The first screw 42 is rotatably mounted on the base 1. The first screw 42 is arranged in a horizontal direction and is connected to the output end of the first driver 41. The first screw 42 can rotate with the output end of the first driver 41.

[0065] The second screw 43 is rotatably mounted on the base 1. The second screw 43 is arranged in a horizontal direction and is connected to the first screw 42. The thread direction of the second screw 43 is opposite to that of the first screw 42.

[0066] The first nut 44 is sleeved on the first screw 42 and can move as the first screw 42 rotates;

[0067] The second nut 45 is sleeved on the second screw 43 and can move as the second screw 43 rotates;

[0068] The first connecting rod 46, the upper end of which is pivotally connected to the first nut 44, and the lower end of which is pivotally connected to the lifting plate 2; and

[0069] The second connecting rod 47 has its upper end pivotally connected to the first nut 44 and its lower end pivotally connected to the lifting plate 2. Thus, when the lifting device needs to be moved, the first driver 41 drives the first screw 42 and the second screw 43 to rotate. The rotation of the first screw 42 causes the first nut 44 to move closer to the second nut 45, and the rotation of the second screw 43 causes the second nut 45 to move closer to the first nut 44. This brings the first nut 44 and the second nut 45 closer together, causing the lower ends of the first connecting rod 46 and the second connecting rod 47 to move downwards, thereby moving the lifting plate 2 downwards and bringing the caster wheels 3 into contact with the ground. When the lifting device does not need to be moved, the first driver 41 drives... The first screw 42 and the second screw 43 rotate. The rotation of the first screw 42 causes the first nut 44 to move away from the second nut 45. The rotation of the second screw 43 causes the second nut 45 to move away from the first nut 44. This causes the first nut 44 and the second nut 45 to move away from each other, thereby driving the lower end of the first connecting rod 46 and the lower end of the second connecting rod 47 to move upward. This causes the lifting plate 2 to move upward, so that the caster wheel 3 is separated from the ground while the base is in contact with the ground. This first lifting drive mechanism 4 has a simple structure, high transmission stability, strong load capacity, and a compact structure, and does not occupy too much space.

[0070] See Figures 2-3 In one embodiment, the first lifting drive mechanism 4 further includes:

[0071] The first bearing 48 is fixed on the base 1;

[0072] The first rotating shaft 49 is located between the first driver 41 and the first screw 42. The first rotating shaft 49 connects the first driver 41 and the first screw 42. The first rotating shaft 49 passes through the center hole of the first bearing 48. The inner ring of the first bearing 48 can rotate with the first rotating shaft 49.

[0073] The second bearing 410 is fixed on the base 1;

[0074] The second rotating shaft 420 is connected to the second screw 43. The second rotating shaft 420 passes through the center hole of the second bearing 410, and the inner ring of the second bearing 410 can rotate with the second screw. The first bearing 48 and the second bearing 410 can support the first screw 42 and the second screw 43, making the rotation of the first screw 42 and the second screw 43 more stable and smooth, ensuring that the first screw 42 and the second screw 43 can operate normally. Secondly, the first bearing 48 and the second bearing 410 can also reduce friction and wear, protect the base 1, the first screw 42 and the second screw 43, and extend the service life of the lifting device.

[0075] In one embodiment, the first rotating shaft 49 and the first screw 42 are integrally formed so that the first rotating shaft 49 and the first screw 42 are connected without connectors, which simplifies the structure and improves the connection strength between the first rotating shaft 49 and the first screw 42.

[0076] In one embodiment, the second rotating shaft 420 and the second screw 43 are integrally formed so that the second rotating shaft 420 and the second screw 43 are connected without connectors, which simplifies the structure and improves the connection strength between the second rotating shaft 420 and the second screw 43.

[0077] For convenient connection between the first connecting rod 46, the second connecting rod 47 and the base 1, see [reference needed]. Figure 2 and Figure 3 In one embodiment, the top surface of the lifting plate 2 is provided with a first connecting seat 6;

[0078] The lower ends of the first connecting rod 46 and the second connecting rod 47 are both provided with the first connecting seat 6, and the lower ends of the first connecting rod, the second connecting rod 47, and the first connecting seat 6 are pivotally connected together by the first pivot member.

[0079] See Figures 2-3 In one embodiment, to facilitate the connection of the first connecting rod 46 and the first nut 44, the first nut 44 is provided with a second connecting seat, and the first connecting rod 46 and the second connecting seat are pivotally connected together by a second pivot member.

[0080] See Figures 2-3 In one embodiment, to facilitate the connection of the second connecting rod 47 and the second nut 45, the second nut 45 is provided with a third connecting seat, and the second connecting rod 47 and the third connecting seat are pivotally connected together by a third pivot member.

[0081] See Figures 1-3 In one embodiment, the first driver 41 includes a motor, the motor body is connected to the base 1, and the output end of the motor is connected to the first screw 42. That is, the rotation of the first screw 42 and the second screw 43 is controlled by electric means. In other words, the operation can be controlled by operating the switch to start and stop the motor, which is simpler and more convenient, and can save manpower.

[0082] Of course, in other embodiments, the first driver 41 can also be a manual turntable, which can drive the first screw 42 and the second screw 43 to rotate by manually turning the turntable.

[0083] In one embodiment, the first screw 42, the second screw 43, the first nut 44, the second nut 45, the first connecting rod 46, and the second connecting rod 47 are all located inside the storage cavity 11, which can improve the space utilization of the storage cavity 11. At the same time, it can also simplify the external structure of the lifting device, making the lifting device more concise and beautiful.

[0084] Of course, in other embodiments, the first lifting drive mechanism 4 may include:

[0085] The motor is mounted on base 1;

[0086] A gear, fitted onto the output shaft of the motor, can rotate with the output shaft of the motor; and

[0087] A rack is provided along the moving direction of the lifting plate 2. The rack meshes with a gear and is connected to the lifting plate 2. Thus, the gear is driven to rotate by the motor, and the rotation of the gear drives the rack to move, thereby moving the lifting plate 2.

[0088] Of course, in other embodiments, a lead screw can be used instead of the gear, and a nut can be used instead of the rack.

[0089] See Figures 1-2 In one embodiment, the lifting device with the function of accommodating casters further includes:

[0090] The second lifting drive mechanism 7 is mounted on the base 1;

[0091] The worktable 8 is connected to the output end of the second lifting drive mechanism 7. The worktable 8 can move up and down with the output end of the second lifting drive mechanism 7, and is used to support the electromechanical equipment. In this way, by operating the second lifting drive mechanism 7, the worktable 8 can be moved to move the electromechanical equipment to the required height position.

[0092] See Figures 1-2 In one embodiment, the second lifting drive mechanism 7 includes an electric push rod, the body of which is connected to the base 1, and the output end of which is connected to the worktable 8. The electric push rod can precisely control the thrust and speed, achieving accurate positioning and motion control. Secondly, the electric push rod does not require the use of any liquids or gases, eliminating the problem of hydraulic oil or gas leaks and reducing environmental pollution. Furthermore, electric push rods typically employ long-life motors and lead screw technology, resulting in relatively low maintenance costs and reducing the cost of the lifting device. Additionally, the electric push rod has a simple structure, making installation and maintenance very convenient.

[0093] Of course, in other embodiments, the second lifting drive mechanism 7 may also include a cylinder or a hydraulic cylinder, a motor, a gear and a rack, or a motor, a lead screw and a nut.

[0094] See Figures 1-2 as well as Figure 4 In one embodiment, the lifting device with the function of accommodating casters further includes:

[0095] The third lifting drive mechanism 9 is located on the worktable 8;

[0096] Clamping plate 10 is located above the worktable 8. Clamping plate 10 is connected to the output end of the third lifting drive mechanism 9. Clamping plate 10 can move up and down with the output end of the third lifting drive mechanism 9. Clamping plate 10 is used to abut against the electromechanical equipment located on the worktable 8, so as to clamp the electromechanical equipment together with the worktable 8, play a positioning role, and make the electromechanical equipment reliably placed on the worktable 8, prevent the electromechanical equipment from falling off the worktable 8 at will, and improve the lifting safety of the electromechanical equipment.

[0097] See Figures 1-2 as well as Figure 4 In one embodiment, the third lifting drive mechanism 9 includes: a second driver 91;

[0098] The third screw 92 is connected to the output terminal of the second driver 91, and the third screw 92 can rotate with the output terminal of the second driver 91; and

[0099] A solenoid 93 is fitted onto the third screw 92 and can move as the third screw 92 rotates. The solenoid 93 is connected to the clamping plate 10. Thus, by operating the second driver 91, the output end of the second driver 91 rotates, driving the third screw 92 to rotate. The rotation of the third screw 92 drives the solenoid 93 to move, thereby moving the clamping plate 10 up and down, enabling the clamping plate 10 to clamp or release the electromechanical equipment. The structure is simple, practical, and low-cost, reducing the cost of the lifting device.

[0100] See Figures 1-2 as well as Figure 4 In one embodiment, the second driver 91 includes a manual turntable. By manually turning the turntable, the third screw 92 can be driven to rotate, thereby enabling the clamping plate 10 to move up and down. The manual turntable has a simple structure and low cost, which can reduce the cost of the lifting device.

[0101] Of course, in other embodiments, the second driver 91 may also include a motor or other rotary driver.

[0102] See Figures 1-2 as well as Figure 4In one embodiment, the third lifting drive mechanism 9 further includes:

[0103] The third bearing 94 is fixed on the worktable 8;

[0104] The third screw 92 is equipped with a third rotating shaft, through which the center hole of the third bearing 94 is passed. The inner ring of the third bearing 94 can rotate with the third rotating shaft. The third bearing serves to support the third screw 92, making its rotation more stable and smooth, ensuring its normal operation. Furthermore, the third bearing 94 also reduces friction and wear, protecting the base 1 and the third screw 92, and extending the service life of the lifting device.

[0105] Of course, in other embodiments, the third lifting drive mechanism 9 may also include:

[0106] The motor is located on the worktable 8;

[0107] A gear, fitted onto the output shaft of the motor, can rotate with the output shaft of the motor; and

[0108] A rack is provided along the moving direction of the clamping plate 10. The rack meshes with a gear and is connected to the clamping plate 10. Thus, the gear is driven to rotate by a motor, and the rotation of the gear drives the rack to move, thereby moving the clamping plate 10.

[0109] Of course, in other embodiments, a lead screw can be used instead of the gear, and a nut can be used instead of the rack.

[0110] See Figures 1-2 as well as Figure 4 In one embodiment, the lifting device with the function of accommodating casters further includes:

[0111] The second guide mechanism 20 connects the worktable 8 and the clamping plate 10. The second guide mechanism 20 is used to guide the movement of the clamping plate 10, so that the clamping plate 10 moves up and down more smoothly and stably.

[0112] See Figures 1-2 as well as Figure 4 In one embodiment, the second guide mechanism 20 includes:

[0113] Guide sleeve 201, the lower end of guide sleeve 201 is connected to worktable 8, and the upper end of guide sleeve 201 extends toward clamping plate 10; and

[0114] The movable rod 202 has its lower end movably inserted into the center hole of the guide sleeve 201, and its upper end is connected to the clamping plate 10. Thus, when the clamping plate 10 moves upward under the drive of the third lifting mechanism 9, the movable rod 202 moves upward along the guide sleeve 201. Conversely, when the clamping plate 10 moves downward under the drive of the third lifting mechanism 9, the movable rod 202 moves downward along the guide sleeve 201, providing excellent guiding function. This design is simple, practical, and low-cost, reducing the cost of the lifting device.

[0115] See Figures 1-2 as well as Figure 4 In one embodiment, there are two sets of second guide mechanisms 20, which are arranged at intervals along the length of the clamping plate 10 to make the movement of the clamping plate 10 smoother and more stable.

[0116] Of course, in other embodiments, the second guide mechanism 20 may include:

[0117] Guide rails are mounted on the worktable 8 and extend along the moving direction of the clamping plate 10; and

[0118] The slider is movably mounted on the guide rail and connected to the clamping plate 10. Thus, when the clamping plate 10 is driven upward by the third lifting drive mechanism 9, the slider moves upward along the guide rail. When the clamping plate 10 is driven downward by the third lifting drive mechanism 9, the slider moves downward along the guide rail, thus enabling the clamping plate 10 to be moved and guided.
