Description

Technical Field

[0001] This utility model relates to a bottom moving mechanism of equipment, and more particularly to a moving lifting universal mechanism. Background Technology

[0002] The base is a crucial component of many production equipment, typically used to directly contact the ground or foundation and transfer the equipment's support force to the ground. Traditional bases are usually fixed to the ground with floor nails to secure the base and equipment. However, most production workshop floors are painted, and using screws to fix equipment to the ground often fails to meet 5S and 6S management standards. Therefore, our company designed a large-platform base. The large platform increases friction with the ground, allowing the equipment's own weight to reliably fix its position. However, the large platform is not easy to move, and the equipment is very heavy. If the equipment's position needs to be adjusted later, it requires multiple people working together, which is time-consuming and labor-intensive. Utility Model Content

[0003] This utility model provides a mobile lifting universal mechanism to solve the above-mentioned technical problems. This utility model is achieved through the following technical solution:

[0004] The mobile lifting omnidirectional mechanism provided in this application includes a chassis, a guide column, a pressure plate, an adjustment device, and at least three omnidirectional wheels. The bottom end of the guide column is connected to the chassis, the pressure plate is located above the chassis, and the pressure plate can move up and down along the guide column. The omnidirectional wheels are mounted on the pressure plate. The chassis has clearance holes corresponding to the positions of the omnidirectional wheels for the omnidirectional wheels to pass through. The adjustment device is used to adjust the height of the pressure plate and can drive the pressure plate to switch between a first position and a second position. When the pressure plate is in the first position, the bottom of the omnidirectional wheel is higher than the bottom surface of the chassis, and when the pressure plate is in the second position, the bottom of the omnidirectional wheel is lower than the bottom surface of the chassis.

[0005] The regulating device can be a manual regulating device or an automatic regulating device, and the automatic regulating device can be an electric regulating device, a hydraulic regulating device, or a pneumatic regulating device.

[0006] Optionally, the adjusting device includes an adjusting nut for applying a downward force to the pressure plate and a first spring for applying an upward force to the pressure plate, the first spring being installed between the pressure plate and the chassis; the outer surface of the guide post has an external thread that matches the adjusting nut, the adjusting nut being threadedly connected to the guide post, and the adjusting nut being located above the pressure plate; the first spring may or may not be fitted over the guide post.

[0007] Preferably, the adjusting nut is provided with a wrench hole.

[0008] Preferably, the guide post is connected to the center of the chassis, the guide post passes through the center hole of the pressure plate and is clearance-fitted with it, and the casters are evenly arranged on the same circumference around the center hole of the pressure plate.

[0009] Furthermore, multiple support rods are installed on the chassis, and the pressure plate has support rod through holes corresponding to the support rods. The lower end of the support rod is connected to the chassis, and the upper end of the support rod is installed in the corresponding support rod through hole with clearance fit.

[0010] Optionally, a second spring is fitted around the support rod, with the upper end of the second spring connected to the pressure plate and the lower end of the second spring being either a free end or connected to the chassis.

[0011] Preferably, the plurality of support rods are evenly arranged on the same circumference around the center of the pressure plate.

[0012] Optionally, the casters are foldable and mounted on a rotatable wheel frame. The wheel frame is rotatably connected to the pressure plate via a horizontally set shaft. Each caster is provided with a wheel frame pressure plate on the pressure plate, which is used to prevent the wheel frame from flipping upward.

[0013] The wheel frame pressure plate is rotatably connected to the pressure plate via a vertical shaft. Rotating the wheel frame pressure plate allows it to switch between a first position and a second position. When the wheel frame pressure plate is in the first position, it can block the wheel frame from above, thus preventing the wheel frame from flipping upwards. When the wheel frame pressure plate is in the second position, it is offset from the wheel frame, allowing the wheel frame to flip upwards.

[0014] Furthermore, the guide post has an insertion hole in the center.

[0015] Compared with the prior art, this application has at least the following beneficial effects:

[0016] 1. This application utilizes the large contact area between the chassis and the ground to increase friction, and the equipment's own weight is used to fix the position. This not only eliminates the need for screw fixing and meets the 5S management standard, but also makes it less likely for the chassis to slip on the ground, resulting in good stability and safe use. This application also adds height-adjustable casters, which allow switching between fixed and movable modes by adjusting the height of the casters, making it easy to fix or move.

[0017] 2. With the adjustment device of this application, multiple casters can be lowered and raised synchronously with just one operation by one operator. Only one operator is needed to move the equipment, which saves time and effort and is easy to operate. Attached Figure Description

[0028] In the description of this utility model, it should also be noted that, unless otherwise explicitly specified and limited, the terms "set," "install," "connect," and "link" should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral connection; 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; and they can refer to the internal connection of two components. Those skilled in the art can understand the specific meaning of the above terms in this utility model based on the specific circumstances.

[0029] like Figures 1-3 As shown, the movable lifting omnidirectional mechanism disclosed in this embodiment includes a chassis, guide column 2, pressure plate 3, adjustment device, and at least three omnidirectional wheels 6. The chassis 1 has a flat bottom surface for large-area contact with the ground or foundation. The bottom end of the guide column 2 is connected to the chassis 1, and the pressure plate 3 is located above the chassis 1, and the pressure plate 3 can move up and down along the guide column 2.

[0030] The casters 6 are mounted on the pressure plate 3, and the chassis 1 has clearance holes 11 for each caster 6 to pass through. Of course, all casters 6 are at the same height.

[0031] The adjustment device is used to adjust the height of the pressure plate 3, which can drive the pressure plate 3 to switch between the first position and the second position. When the pressure plate 3 is in the first position, the bottom 61 of the universal wheel 6 is higher than the bottom surface of the chassis 1. When the pressure plate 3 is in the second position, the bottom 61 of the universal wheel 6 is lower than the bottom surface of the chassis 1.

[0032] In the initial state, the pressure plate 3 is in the first position. At this time, the bottom surface of the chassis 1 is in contact with the ground or foundation, and the bottom 61 of the caster wheel 6 is higher than the bottom surface of the chassis 1, so it is not in contact with the ground. The moving and lifting universal mechanism is fixed to the ground steadily.

[0033] Then, the pressure plate 3 can be driven downward to the second position by the adjustment device. The pressure plate 3 simultaneously drives the casters 6 to move down from the corresponding clearance holes 11 on the chassis 1, so that the bottom of each caster 6 is lower than the bottom surface of the chassis 1. At this time, the casters 6 replace the chassis 1 in contact with the ground or foundation, and the chassis 1 is lifted off the ground under the action of the reaction force. The friction between the chassis 1 and the ground is released, and at the same time, multiple casters 6 are in contact with the ground. At this time, the entire mechanism and the main body of the equipment on the mechanism can be moved very easily. After the casters 6 are used to move the moving lifting universal mechanism and the main body of the equipment installed on it to the predetermined position, the pressure plate 3 is driven upward by the adjustment device, which then drives the casters 6 to rise up and leave the ground. At the same time, the chassis 1 is put back into contact with the ground under the action of the reaction force, thus fixing the equipment in the new position.

[0034] It is worth noting that the adjustment device can be either manual or automatic. For example, ... Figures 1-3 As shown, the adjustment device is a manual adjustment device, which includes an adjustment nut 4 and a first spring 5. The first spring 5 is installed between the pressure plate 3 and the chassis 1. Under the action of the first spring 5, the pressure plate 3 tends to move upward away from the chassis 1.

[0035] The guide post 2 has an external thread that matches the adjusting nut 4 on its outer surface. The adjusting nut 4 is threadedly connected to the guide post 2 and is located above the pressure plate 3. When the adjusting nut 4 is turned downwards, it moves downwards, and the pressure plate 3, under the downward pressure of the adjusting nut 4, overcomes the elastic force of the first spring 5 and moves downwards. This causes the caster 6 to move down from the corresponding clearance hole 11 on the chassis 1 until the wheel bottom 61 is below the bottom surface of the chassis 1. At this time, the caster 6 replaces the chassis 1 in contact with the ground or foundation. Similarly, when the adjusting nut 4 is turned upwards, it moves upwards, and the pressure plate 3 is lifted upwards by the first spring 5 until it leaves the ground. The chassis 1 also re-contacts the ground under the reaction force. To facilitate turning the adjusting nut 4, a wrench hole 41 is provided on the adjusting nut 4; preferably, the wrench hole 41 is radially arranged.

[0036] In other embodiments, the adjusting device is an automatic adjusting device mounted on the guide column 2. This automatic adjusting device can move the pressure plate 3 up and down. The automatic adjusting device can be an electric adjusting device, a hydraulic adjusting device, or a pneumatic adjusting device. The electric adjusting device can be an electric push rod, with its output connected to the pressure plate 3; the hydraulic adjusting device can be a hydraulic cylinder; and the pneumatic adjusting device can be a pneumatic cylinder, with its output connected to the pressure plate 3. Preferably, a first spring 5 is also installed between the pressure plate 3 and the chassis 1. When the automatic adjusting device releases force, the pressure plate 3 returns to its initial position under the action of the first spring 5.

[0037] To make the mobile lifting universal mechanism more stable, the guide column 2 is connected to the center of the chassis 1. The guide column 2 passes through the center hole of the pressure plate 3 and is fitted with it with clearance. The universal wheels 6 are evenly arranged on the same circumference around the center hole of the pressure plate 3.

[0038] To further improve the stability of the pressure plate 3 during vertical movement, multiple support rods 7 are installed on the chassis 1. The pressure plate 3 has corresponding support rod through holes for each of the support rods 7. The lower end of each support rod 7 is connected to the chassis 1, and the upper end of each support rod 7 is fitted into the corresponding support rod through hole on the pressure plate 3 with a clearance fit. The multiple support rods 7 provide a certain guiding effect for the pressure plate 3 and prevent the pressure plate 3 from rotating relative to the guide post 2, ensuring that the caster wheel 6 is always directly above the corresponding clearance hole 11 on the chassis 1.

[0039] It is worth noting that the first spring 5 can be fitted onto the guide post 2, such as... Figure 1 As shown; several first springs 5 ​​can also be evenly arranged around the guide post 2.

[0040] In some embodiments, a first spring 5 is sleeved on the guide post 2, and several second springs 71 are also provided between the pressure plate 3 and the chassis 1. The second springs 71 are evenly arranged on the same circumference around the first spring 5. Preferably, the number of second springs 71 is the same as that of the support rod 7, and each second spring 71 is sleeved on the outside of the support rod 7. The upper end of the second spring 71 is connected to the pressure plate 3, and the lower end of the second spring 71 is a free end or connected to the chassis 1. When the pressure plate 3 moves downward, the second springs 71 can play a role in buffering and vibration reduction.

[0041] It is worth noting that the number of casters 6 should be set reasonably according to needs, and setting 3 can basically meet the needs of smooth movement. Figure 1 In the center, there are four casters 6, and correspondingly four clearance holes 11. As a priority, there are also four support rods 7, which are evenly arranged on the same circumference around the guide post 2.

[0042] The shapes of the chassis 1 and the clearance hole 11 are reasonably set according to the needs; preferably, the chassis 1 is a circular disc and the clearance hole 11 is a circular hole.

[0043] To facilitate connection with the equipment, the guide post 2 has a central insertion hole; for example Figure 5 As shown, the lower end of the support column 8 of the equipment can be inserted into the guide column 2.

[0044] To prevent the operator's feet from touching the caster wheel 6 during operation, such as... Figure 6 As shown, in some embodiments of this utility model, the caster wheel 6 is foldable. Specifically, the caster wheel 6 is mounted on a flip-up wheel frame 62, which is rotatably connected to the pressure plate 3 via a horizontally arranged shaft 63. By flipping the caster wheel 6 upwards around the shaft 63, the caster wheel 6 can be folded up. Simultaneously, when the pressure plate 3 is moved downwards to the second position, to prevent the caster wheel 6 from folding during movement, a wheel frame pressure plate 81 is also provided on the pressure plate 3 for each caster wheel 6. The wheel frame pressure plate 81 is used to block the wheel frame 62 from flipping upwards. The wheel frame pressure plate 81 is rotatably connected to the pressure plate 3 via a vertical shaft 82. Rotating the wheel frame pressure plate 81 allows it to switch between the first and second positions. When the wheel frame pressure plate 81 is in the first position, it blocks the wheel frame 62, thus preventing the wheel frame 62 from flipping upwards. Please refer to [link to relevant documentation]. Figure 6At this point, the wheel frame pressure plate 81 is in the first position; when the wheel frame pressure plate 81 is in the second position, the wheel frame pressure plate 81 is offset from the wheel frame 62, and the wheel frame 62 can be flipped upwards. Furthermore, a vertical set bolt 83 is installed on the wheel frame pressure plate 81. When the wheel frame pressure plate 81 is in the first position, the lower end of the set bolt 83 holds the wheel frame 62 in place, preventing it from folding. This application utilizes the large contact area between the chassis and the ground to increase friction, reliably fixing the position using the equipment's own weight. Moreover, slippage between the chassis and the ground is unlikely, resulting in good stability and safe use. Simultaneously, only one operator is needed to move the entire device, saving time and effort, and making operation convenient.

[0045] The above are merely preferred embodiments of this utility model and are not intended to limit the scope of this utility model. Various modifications and variations can be made to this utility model by those skilled in the art. Any modifications, equivalent substitutions, or improvements made within the spirit and principles of this utility model should be included within the protection scope of this utility model.
