[0026] The embodiments of the utility model are described in detail below in combination with the drawings, but the utility model can be implemented in multiple different ways limited and covered by the following.
[0027] Please refer to Figures 1-5 The utility model provides a technical scheme: a multifunctional hoisting tool, including gravity center adjusting device, frame 1 and hoisting head, frame 1 is C-shaped, gravity center adjusting device includes hanging beam 2 fixed on the upper end of frame 1, a plurality of hoisting holes 21 are arranged on hanging beam 2 along the horizontal direction and are spaced apart, and counterweight 22 is arranged on hanging beam 2 along the arrangement direction of hoisting hole 21 and is slidably arranged, hoisting head includes fixed part 3 installed on the lower end of frame 1 and movable part in rotation with fixed part 3, and movable part is used for installing workpiece.
[0028] In operation, first, the workpiece is installed on the movable part, then the lifting device is inserted into the lifting hole 21 of the lifting beam 2, the overall multifunctional lifting tool is lifted together with the workpiece, before lifting, the lifting hole 21 at different positions can be selected according to the shape and size of the workpiece, after lifting, if the workpiece does not reach the required angle for installation, the counterweight 22 can be slid to change the center of gravity of the overall multifunctional lifting tool to adjust the angle of the workpiece, to ensure the stability of the workpiece during lifting or to make the workpiece more convenient to install. Some workpieces, such as tubular workpieces, need to be assembled in the lifting state, and during assembly, the part of the workpiece used for assembly needs to be aligned with the installation position. Since the movable part is rotatably arranged on the fixed part 3, the workpiece can be rotated synchronously with the movable part when the workpiece is installed on the movable part, so as to realize rotation in the lifting state and make the workpiece rotate to the appropriate position, facilitating subsequent installation of the workpiece in the lifting state.
[0029] The device can realize large-span center of gravity adjustment through different lifting holes 21, and can also realize fine stepless center of gravity adjustment through the counterweight 22, so as to better control the angle of the workpiece. Meanwhile, the workpiece is installed on the movable part, and the movable part is rotatably arranged on the fixed part 3, so that the rotation of the workpiece can be realized in the lifting state, which facilitates subsequent installation of the workpiece to the assembly position in the lifting state, making the lifting process of the workpiece safer and the subsequent installation more convenient.
[0030] Specifically, as shown in Figure 1 , the surface of the lifting beam 2 is provided with a sliding groove 23 penetrating the lifting beam 2, the length direction of the sliding groove 23 is the same as the arrangement direction of the lifting holes 21, the counterweight 22 includes a connecting rod and first and second parts with the same weight, the connecting rod passes through the first part, the sliding groove 23 and the second part in sequence to arrange the first and second parts on both sides of the lifting beam 2, maintaining the balance of both sides of the lifting beam 2.
[0031] Specifically, as shown in Figure 4 , the side of the movable part facing the fixed part 3 is provided with a sleeve, a plurality of bearings are fixedly arranged in the sleeve, and the side of the fixed part 3 facing the movable part is provided with a boss fixedly connected with the inner ring of the bearing to realize the rotary connection of the fixed part 3 and the movable part.
[0032] Specifically, Figure 1 , a first example of the movable part is shown, in this example, the movable part includes a mounting disc 41, a plurality of mounting holes are arranged on the mounting disc 41 at equal intervals in the circumferential direction with the rotation axis of the movable part as the center, which is suitable for workpieces with flanges, and the workpiece can be fastened with bolts after the flange of the workpiece is attached to the mounting disc 41, which is more convenient to install and more stable and safe after installation.
[0033] Specifically,Figure 3 Another example of a movable portion is shown. In this example, the movable portion includes a mounting tube 42 and positioning rods 43. A plurality of positioning rods 43 are provided. The plurality of positioning rods 43 are penetrated through the wall of the mounting tube 42, and the length direction of the positioning rods 43 is perpendicular to the rotation axis of the movable portion.
[0034] The positioning rod 43 is threadedly engaged with the mounting tube 42, or an adjustment mechanism is provided in the mounting tube 42 for adjusting the positioning rod 43 to the position of the rotating axis of the movable part. In the actual lifting process, it is impossible for the workpiece to have a flange. In this case, the mounting tube 42 can be inserted into the inner cavity of the workpiece. If the positioning rod 43 is threadedly engaged with the mounting tube 42, the positioning rod 43 can be directly rotated to abut against the inner cavity of the workpiece to achieve fixation of the workpiece. If an adjustment mechanism is provided in the mounting tube 42, the positioning rod 43 can be controlled by the adjustment mechanism to move and abut against the inner cavity of the workpiece to achieve fixation of the workpiece.
[0035] When the positioning rod 43 is threadedly engaged with the mounting tube 42, the positioning rod 43 can abut the workpiece from the inside of the workpiece, or the workpiece can be placed into the mounting tube 42 so that the positioning rod 43 abuts the outer surface of the workpiece to fix the workpiece, which has a wider range of applications;
[0036] When the position of the positioning rod 43 is controlled by the adjustment mechanism, the workpiece can only be fixed by the positioning rod 43 abutting against the inner wall of the workpiece;
[0037] Specifically, such as Figure 5 As shown, the adjustment mechanism includes an adjustment rod 44 threadedly engaged in the mounting tube 42 and a protrusion rotatably arranged at one end of the adjustment rod with the axis of the adjustment rod 44 as the rotation axis. A swing arm 45 is hinged on the protrusion, and the end of the swing arm 45 away from the adjustment rod 44 is rotatably connected to the positioning rod 43. By rotating the adjustment rod 44, the adjustment rod 44 is moved along its axial direction, driving the boss to move synchronously. When the end of the swing arm 45 connected to the boss approaches the positioning rod 43, the positioning rod 43 will extend outward away from the inner cavity of the mounting tube 42, and when the end of the swing arm 45 connected to the boss is away from the positioning rod 43, the positioning rod 43 will be retracted into the inner cavity of the mounting tube 42, thereby achieving the effect of controlling the movement of the positioning rod 43 to fix the workpiece on the mounting tube 42.
[0038] Specifically, a number of positioning rods 43 are arranged on the mounting tube 42 at equal intervals around the rotating axis of the movable part. When the workpiece is fixed by the positioning rods 43, the workpiece can be centered so that the axis of the workpiece coincides with the rotating axis of the movable part. In this way, when the workpiece is subsequently rotated, the position of the workpiece can be guaranteed not to change. When the workpiece is subsequently connected to the equipment or other assembly parts, the workpiece can be directly rotated so that the workpiece rotates around its own axis, and the position of the workpiece will not change, thereby preventing the need to adjust the position of the workpiece after rotating the workpiece.
[0039] In some examples, a limiting device for limiting the rotation of the movable part is provided between the fixed part 3 and the movable part. The limiting device includes a screw rod 51 and a nut 52. A circular hole for accommodating the screw rod 51 is provided on the side of the fixed part 3 facing the movable part. One end of the screw rod 51 is inserted into the circular hole, and the other end abuts against the movable part. The nut 52 is threadedly engaged with the screw rod 51. Figure 2 As shown, by rotating the nut 52, the position of the nut 52 on the screw rod 51 is controlled, and the end of the screw rod 51 away from the nut 52 will abut against the end face of the movable part, and the nut 52 will abut against the end face of the fixed part 3. By moving the nut 52 away from the contact side of the screw rod 51 and the movable end, the friction force of the contact surface between the nut 52 and the fixed part 3 is increased, and at the same time, the friction force of the contact surface between the screw rod 51 and the movable part is increased, so as to achieve relative fixation of the movable part and the fixed part 3, ensure that the movable part does not rotate during the lifting process, and ensure the stability of the workpiece during the lifting process.
[0040] Specifically, a rubber pad 46 is fixedly provided on one end of the positioning rod 43 that is in contact with the workpiece to prevent the positioning rod 43 from damaging the workpiece and ensure the safety of the workpiece.
[0041] like Figure 1 As shown, the fixing portion 3 and the frame 1 are connected by bolts to realize the replacement of the lifting head. Different lifting heads are replaced according to different workpieces.
[0042] like Figure 1 As shown, the frame 1 consists of two parallel horizontal bars and a vertical bar connecting the two horizontal bars. The lifting beam 2 is fixed to the end of one of the horizontal bars away from the vertical bar, and the lifting head is fixed to the end of the other horizontal bar away from the vertical bar. In this way, the workpiece can be sent into the space with obstructions above through the frame 1, solving the problem that the workpiece inside the structure cannot be directly lifted.
[0043] The above are merely preferred embodiments of the present invention and are not intended to limit the present invention. Those skilled in the art will readily appreciate that the present invention is susceptible to various modifications and variations. Any modifications, equivalent substitutions, or improvements made within the spirit and principles of the present invention shall be included within the scope of protection of the present invention.
