[0035] See also Figures 1 to 4 As shown, this embodiment provides a lifting and pitching upper mounting device, including a lifting mechanism 1, a pitching mechanism 2 and an upper mounting mechanism 3, wherein:

[0036] The lifting mechanism 1 includes a base 11 and a bearing platform 12. The base 11 is provided with a first driving member 13, which is used to drive the bearing platform 12 to rise or fall relative to the base 11.

[0037] The pitch mechanism 2 includes a pitch member 21 and a pitch bracket 22. The pitch bracket 22 is mounted on the supporting platform 12. The middle portion of the pitch member 21 is rotatably connected to the pitch bracket 22 via a first pin 24. A second driving member 23 is provided on the supporting platform 12. The driving end of the second driving member 23 is hingedly connected to a portion of the pitch member 21 located on one side of the first pin 24. The second driving member 23 is used to drive the pitch member 21 to rotate about the first pin 24.

[0038] The loading mechanism 3 is provided on the pitching member 21 and is used for driving the workpiece to be loaded to translate and flip.

[0039] Therefore, through the cooperation of the jacking mechanism 1, the pitching mechanism 2 and the loading mechanism 3, the function of lifting the workpiece to the target height to complete the loading is achieved, so as to cope with the working conditions such as uneven ground on site, high-altitude operation, limited loading space and angle, etc., reducing labor input, lowering construction difficulty and improving work efficiency.

[0040] Optionally, height measuring sensors 25 are respectively provided at both ends of the pitching member 21 , and the height measuring sensors 25 are connected to the second driving member 23 for signal transmission, so as to adjust the workpiece to a target height.

[0041] When adjusting the height of the workpiece, the lifting mechanism 1, the pitching mechanism 2 and the loading mechanism 3 are adjusted together. Especially when loading at a specific angle in a specific space, the lifting mechanism 1 determines the approximate height, the pitching mechanism 2 determines the pitching angle, and the loading mechanism 3 performs operations such as forward movement and flipping.

[0042] The first driving member 13 is preferably a scissors-type lift, which can provide vertical bearing capacity and be height-adjustable. The specific form of the first driving member 13 is not limited here; the second driving member 23 is preferably an electric push rod, and can also be a cylinder, electric cylinder, hydraulic cylinder, etc., which can provide a driving force for controlling the pitch angle of the pitch member 21. The specific form of the second driving member 23 is not limited here.

[0043] Specifically, the upper loading mechanism 3 includes a forward moving component 31, a flipping component 32 and a clamping component 33, wherein:

[0044] The forward moving assembly 31 includes a forward moving track 311, which is mounted on the pitching member 21 or directly serves as the pitching member 21 (the latter is used as an example in this embodiment to simplify the structure). A forward moving member 312 is slidably mounted on the forward moving track 311, and the forward moving member 312 is driven by a third driving member 313 to move along the forward moving track 311.

[0045] The flip assembly 32 includes a flip member 321 rotatably mounted on the forward moving member 312 , and the flip member 321 is driven by a fourth driving member 322 to rotate relative to the forward moving member 312 ;

[0046] The clamping assembly 33 is disposed on the flip member 321 and is used to fix or release the workpiece.

[0047] Therefore, through the cooperation of the forward moving component 31, the flipping component 32 and the clamping component 33, the workpiece can be moved forward, flipped, clamped and other actions can be achieved, meeting the requirements of stable transfer and accurate alignment during the loading process, greatly reducing labor input and improving loading efficiency.

[0048] In addition, the functional components of the upper mounting mechanism 3 can be increased or decreased according to the action requirements. For example, when only the forward movement function is required, the clamping component 33 can be directly installed on the forward movement component 312; for example, when the horizontal rotation function is also required, the rotation component can be installed on the flip component 321, and the clamping component 33 can be installed on the rotation component. No further structural expansion is done here.

[0049] Optionally, the forward rail 311 includes two C-shaped channel steels 3111 arranged in parallel, with the notches of the two C-shaped channel steels 3111 facing outward respectively. The forward member 312 is arranged above the forward rail 311, and the two sides of the forward member 312 are provided with limiting portions 3121 extending to the outside of the two C-shaped channel steels 3111. The limiting portions 3121 on each side are provided with limiting portions 314 that slide or roll in cooperation with the notches of the corresponding C-shaped channel steels 3111.

[0050] It should be noted that the structure in which the notches of the two C-shaped channel steels 3111 face outward and cooperate with the forward moving member 312 on the outside notches notches accurately guide the forward moving member 312 and form a reliable support. Compared with the structure on the market in which the notches face inward, the distance between the two C-shaped channel steels 3111 can be reduced while ensuring that the forward moving member 312 is sufficiently stable, thereby effectively controlling the volume of the forward moving rail 311.

[0051] Optionally, the limiting member 314 is preferably a roller bearing, the shaft of the roller bearing is installed on the limiting portion 3121, the wheel of the roller bearing is embedded in the groove of the C-shaped channel steel 3111 and rolls together, and at least two roller bearings are provided on the limiting portion 3121 to ensure that the limiting member 314 is only displaced along the length direction of the C-shaped channel steel 3111 and to reduce movement wear.

[0052] In addition to the rolling fit of roller bearing parts and C-shaped channel steel 3111, the limiter 314 can also adopt the sliding fit of slider parts and C-shaped channel steel 3111 to meet the requirements of reducing wear and ensuring displacement accuracy. The specific form of the limiter 314 is not limited here.

[0053] Furthermore, a notch 3112 is provided on the upper edge of the end of the C-shaped channel steel 3111. This notch 3112 facilitates the wheel portion of the roller bearing to enter and exit the notch of the C-shaped channel steel 3111, thereby improving the convenience of installation and maintenance of the stopper 314. Furthermore, since the notch 3112 is located on the upper edge of the notch of the C-shaped channel steel 3111, there is no need to worry about the wheel portion of the roller bearing falling out of the notch of the C-shaped channel steel 3111 during operation. Furthermore, a stopper 3113 is provided on the C-shaped channel steel 3111 to limit the travel of the forward moving member 312, ensuring that the forward moving member 312 operates within the appropriate travel range.

[0054] Optionally, a fixed base plate 3114 is provided between the two C-shaped channel steels 3111, and the fixed end of the third driving member 313 is installed on the fixed base plate 3114. The driving end of the third driving member 313 is connected to the forward moving member 312 to drive the forward moving member 312 to move along the length direction of the C-shaped channel steel 3111.

[0055] The third driving member 313 is preferably an electric push rod, and can also be a pneumatic cylinder, an electric cylinder, a hydraulic cylinder, etc., which can provide driving force along the length direction of the C-shaped channel steel 3111. The specific form of the third driving member 313 is not limited here.

[0056] Optionally, two forward moving members 312 are provided on the forward moving track 311 , and the two forward moving members 312 are respectively driven by a third driving member 313 to move in the same direction or in the opposite direction.

[0057] In particular, a pull-wire encoder is provided on the fixed base plate 3114, and the pull-wire end of the pull-wire encoder is fixed on the forward moving member 312. The pull-wire encoder is used to measure the moving distance of the forward moving member 312 in real time, thereby facilitating the monitoring of the displacement of each forward moving member 312. For the two forward moving members 312, under the action of the two third driving members 313, they can realize reverse, same speed or differential movement, or move in the same direction at a fixed distance to meet different loading needs.

[0058] Optionally, a mounting portion 3122 for mounting the flip member 321 is provided on the forward moving member 312, and the flip member 321 includes a beam 3211, and the middle portion of the beam 3211 is connected to the mounting portion 3122 via a second pin shaft 323, and the fixed end of the fourth driving member 322 is hinged to the mounting portion 3122, and the driving end of the fourth driving member 322 is hinged to the portion of the beam 3211 located on the side of the second pin shaft 323 to drive the flip member 321 to rotate around the second pin shaft 323, and support arms 3212 are symmetrically provided at both ends of the beam 3211, and the clamping assembly 33 is installed at the end of the support arm 3212.

[0059] The fourth driving member 322 is preferably an electric push rod, and can also be a pneumatic cylinder, an electric cylinder, a hydraulic cylinder, etc., which can provide a driving force for pushing and pulling the flip member 321 on one side. The specific form of the fourth driving member 322 is not limited here, and is not limited to installing the fourth driving member 322 on one side of the second pin shaft 323. The fourth driving member 322 can also be installed on both sides of the second pin shaft 323 to improve the balance stability of the flip member 321.

[0060] Furthermore, the angle of rotation of the flip member 321 around the second pin shaft 323 relative to the horizontal plane is -45° to 45°. Thanks to the outward-turned form of the slot, the forward track 311 can be made relatively narrow, so that the flip member 321 can have a larger rotation angle, so that the workpiece can be accurately placed in place during the installation process.

[0061] In particular, a first bracket is provided on the beam 3211, an absolute encoder is provided on the first bracket, a second bracket is provided on the mounting portion 3122, and the rotor of the absolute encoder is fixedly connected to the second bracket. The absolute encoder is used to measure the rotation angle of the flip part 321 in real time, thereby facilitating the monitoring of the rotation angle of each flip part 321 and ensuring that the workpiece reaches the target position accurately.

[0062] Optionally, the axial direction of the first pin shaft 24 is perpendicular to the axial direction of the second pin shaft 323 , that is, the pitching member 21 and the flipping member 321 rotate in different directions, so that the adjustment range of the workpiece position is maximized.

[0063] Optionally, the clamping assembly 33 includes an electric suction cup 331, which adsorbs the workpiece by generating electromagnetic force. Fixed baffles 332 are provided on the flip part 321 and on both sides of the electric suction cup 331. The fixed baffles 332 on both sides are used to limit the workpiece, facilitate accurate pre-clamping of the workpiece, and ensure the stability of the workpiece under electromagnetic force adsorption.

[0064] In summary, the lifting and pitching loading device can fully automate the process from loading and clamping the workpiece, lifting to a certain height, tilting to a certain angle, forward feeding, flipping and adjusting to assembly, reducing labor input, high operating efficiency, and with forward movement, flipping and clamping functions, meeting a variety of loading requirements.
