[0026] Referring to Figures 1-4 A lifting device for mechanical equipment installation, including the base 1 of four universal wheels are fixedly installed at bottom, four universal wheels ensure that the device is flexible on the ground or work platform. The vertical plate 2 is fixedly connected on the top of the base 1, and the vertical plate 2 provides a stable support frame for the installation of the whole device for subsequent components. The lifting plate 3 is arranged above the base 1, and the lifting plate 3 constitutes a stable and height-adjustable work platform, which provides great convenience for the installation and positioning of mechanical equipment. The sliding rod 4 is fixedly connected on the top of the base 1, and the cross rod 5 and the lifting lead screw 6 are rotatably connected on the top of the base 1 respectively, the lifting lead screw 6 is screw-connected with the lifting plate 3, the sliding rod 4 is vertically slidably connected with the lifting plate 3, and a pair of clamping plates 9 are arranged on the lifting plate 3; the lifting plate 3, the cross rod 5 and the lifting lead screw 6 jointly constitute a stable triangular support structure, which makes the lifting plate 3 bearing mechanical equipment more uniform in stress during lifting, thereby reducing the risk of mechanical equipment falling due to uneven stress and ensuring the stability and safety of equipment lifting process.
[0027] Also includes:
[0028] The first drive assembly is used to drive the lifting screw 6 to rotate;
[0029] The second drive assembly is used to drive the two clamping plates 9 to move synchronously or in opposite directions. The synchronous or opposite movement of the two clamping plates 9 is to adapt to different specifications and sizes of mechanical equipment and to clamp and fix them, so as to prevent the mechanical equipment from shaking or falling during lifting.
[0030] The first drive assembly includes a rotating shaft 17 rotatably connected to the vertical plate 2, one end of the rotating shaft 17 is fixedly connected with a worm gear 18, the vertical plate 2 is rotatably connected with a worm 19, the worm gear 18 and the worm 19 are engaged, and the transmission mode of the worm gear 18 and the worm 19 not only ensures the stable transmission of power, but also realizes the precise control of height. One end of the worm 19 is fixedly connected with a bevel gear three 20, and a bevel gear four 21 is fixedly sleeved on the lifting screw 6, and the bevel gear three 20 and the bevel gear four 21 are engaged. The engagement of the bevel gear three 20 and the bevel gear four 21 makes the rotation of the worm 19 transmitted to the lifting screw 6, and makes the lifting screw 6 rotate, so as to realize the lifting and falling of the lifting plate 3.
[0031] The vertical plate 2 is arranged in a concave shape, the concave side of the vertical plate 2 is the front surface, and the worm gear 18 and the worm 19 are arranged on the concave side of the vertical plate 2. This setting not only protects the transmission components from external interference, but also makes the whole structure more compact and beautiful.
[0032] The second drive assembly includes a rotating shaft 13 rotatably connected to the top of the base 1, a driving gear 14 is fixedly sleeved on the rotating shaft 13, a driven gear 15 is fixedly sleeved on the cross rod 5, and the driving gear 14 and the driven gear 15 are engaged. The rotation of the driving gear 14 drives the driven gear 15 to rotate, and the driven gear 15 drives the cross rod 5 to rotate.
[0033] The second drive assembly further includes a pair of connecting ears 7 fixedly connected to the top of the lifting plate 3, a same bidirectional screw 8 is rotatably connected to the opposite side walls of the two connecting ears 7, the bidirectional screw 8 is threadedly connected with the clamping plate 9, one end of the bidirectional screw 8 close to the cross rod 5 is fixedly connected with a bevel gear two 12, a bevel gear one 11 is fixedly sleeved on the cross rod 5, and the bevel gear one 11 and the bevel gear two 12 are engaged. It needs to be pointed out that the clamping plate 9 is horizontally slidably connected to the top of the lifting plate 3, which is to ensure that the two clamping plates 9 can move stably and horizontally along the axial direction of the bidirectional screw 8.
[0034] The top of the rotating rod 13 is fixedly connected with a first ratchet wheel 16, and the end of the rotating shaft 17, away from the worm wheel 18, is fixedly connected with a second ratchet wheel 23, so that the first ratchet wheel 16 and the second ratchet wheel 23 provide a convenient control mode for the operator. The base 1, the vertical plate 2 and the lifting plate 3 are all fixedly provided with protective covers 22. The protective covers 22 add a safety line to the device, effectively prevent the influence of dust on the gear transmission structure such as the bevel gear 11 and the bevel gear 12, thereby improving the service life of the structure and the accuracy of transmission.
[0035] The lifting plate 3 is rotatably connected with a rotating column 10, and the rotating column 10 is fixedly connected with the bevel gear 11. The arrangement ensures the stability of the bevel gear 11 when rotating and the bevel gear 12 when rotating driven by the bevel gear 11.
[0036] The rotating column 10 and the bevel gear 11 are both provided with cross ports 24 for vertical sliding of the cross rod 5. The arrangement of the cross ports 24 ensures that the vertical movement of the lifting plate 3 and the rotation of the cross rod 5 do not affect each other.
[0037] The utility model can be described by the following operation mode to illustrate its functional principle:

[0039] The rotating rod 13 in the driving assembly two drives the driving gear 14 to rotate, so the driven gear 15 also rotates because it is engaged with the driving gear 14. When the driven gear 15 rotates, it drives the cross rod 5 to rotate, and the cross rod 5 drives the bevel gear 11 to rotate, and the bevel gear 11 drives the bidirectional screw 8 to rotate, because the two clamping plates 9 are respectively threadedly connected with the bidirectional screw 8, so they will move synchronously, thereby clamping the mechanical equipment.
[0040] When the mechanical equipment is clamped and fixed stably, the rotating shaft 17 in the driving assembly one drives the worm wheel 18 to rotate, so the worm gear 19 also rotates because it is engaged with the worm wheel 18. At the same time, because the lifting screw 6 is fixedly provided with the bevel gear four 21, and the bevel gear three 20 and the bevel gear four 21 are engaged, so when the worm gear 19 rotates, it drives the lifting screw 6 to rotate. With the rotation of the lifting screw 6, the lifting plate 3, which is threadedly connected with the lifting screw 6, moves in the vertical direction. At this time, the height of the lifting plate 3 can be adjusted according to the needs to adapt to different working scenes.
[0041] The above merely describes a preferred embodiment of the present application, and the protection scope of the present application is not limited thereto, and any skilled person in the art, according to the technical scheme and the inventive concept of the present application, makes equivalent replacement or change within the technical range disclosed by the present application, which should be covered within the protection scope of the present application.
