DETAILED DESCRIPTION

[0032] Exemplary embodiments will be described in detail herein, examples of which are shown in the accompanying drawings. When the following description refers to the drawings, the same numbers in different drawings represent the same or similar elements unless otherwise indicated. The embodiments described in the following exemplary embodiments do not represent all embodiments consistent with the present disclosure. Instead, they are merely examples of devices consistent with some aspects of the present disclosure as detailed in the appended claims.

[0033] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0034] Embodiment 1:

[0035] like Figures 1 to 6 As shown, this embodiment proposes an electric equipment lifting device, including a crossbeam 1, a mounting frame 2, an anti-sway bar 3, a limiting mechanism 4 and a control component 5 arranged inside the crossbeam.

[0036] Among them, a cavity 6 is opened inside the crossbeam 1 used as a lifting and hoisting support, and a slider 8 is arranged at the bottom end of the cavity 6. In order to ensure that the control component 5 drives the slider 8 to move to both sides, a connecting plate 9 is installed on the lower side of the slider 8. A connecting hole 10 which is connected to the cavity 6 is opened on the lower side of the outside of the crossbeam 1. The lower end of the connecting plate 9 extends from the inside of the connecting hole 10 to the lower side of the outside of the crossbeam 1, and a mounting frame 2 is installed at the lower end of the connecting plate 9. A winding wheel 11 is arranged inside the mounting frame 2. The two ends of the winding wheel 11 are rotatably connected to the two sides inside the mounting frame 2 respectively, and can be rotated by a winding motor 18 installed on one side of the outside of the mounting frame 2 to retract and release the lifting rope 12 wound around the outside of the winding wheel 11.

[0037] A transverse anti-sway bar 3 is arranged at the lower part of the outside of the crossbeam 1, and a transverse sliding hole 13 is provided on the upper side of the anti-sway bar 3, and a connecting block 14 is arranged inside the sliding hole 13, and the connecting block 14 can slide to both sides inside the sliding hole 13, and the lower end of the lifting rope 12 passes from the upper side to the lower side of the connecting block 14, and the lifting rope 12 and the connecting block 14 are fixedly connected together, and the winding wheel 11 can drive the connecting block 14 to move up and down when the lifting rope 12 is wound and released, and rollers 15 are arranged on the upper and lower sides and both sides of the connecting block 14, and the anti-sway bar 3 is provided with sliding grooves 16 on the upper and lower sides, and the connecting block 14 is limited by the rollers 15 and the sliding grooves 16. The anti-sway bar 3 can be used to reduce the length of the free end of the lifting rope when lifting the power equipment, reduce the swing amplitude, and increase the stability when lifting the power equipment.

[0038] Limit blocks 401 are installed on both sides of the outside of the anti-sway bar 3, and support plates 7 are installed on both sides of the outside of the beam 1. There are walking wheels at the front and rear lower ends of both sides of the outside of the support plates 7, which are convenient for moving the power equipment after lifting. Limit holes 402 are opened on the support plates 7, which cooperate with the limit blocks 401 to form a limit mechanism 4, so that the anti-sway bar 3 can only move up and down along the inside of the limit holes 402 through the limit blocks 401, pulleys 19 are set on both sides of the front and rear lower ends of the slider 8, and two clamping plates 20 are set at the bottom end of the cavity 2 inside the beam 1. The clamping plates 20 ensure the stability of the slider 8 during movement, clamp the slider 8 in the middle position between the two clamping plates 20, and prevent the slider 8 from moving up.

[0039] Embodiment 2:

[0040] The solution in Example 1 is further introduced below in combination with a specific working method, as described below:

[0041] The slider 8 is driven to move to both sides by the control component 5 inside the cavity 6. A driving pulley 501 and a driven pulley 502 are respectively arranged on both sides of the top of the cavity 6. A servo motor 505 is installed on the side of the upper end of the outside of the beam 1 close to the driving pulley 501. The rotating shaft on the lower side of the servo motor 505 is fixed to the driving pulley 501. The driving pulley 501 is driven to rotate by the servo motor 505. Interlocking pulleys 503 are arranged on both sides of the upper end of the slider 8. The driving pulley 501 and a interlocking pulley 503 close to it form a group of movable pulleys, and the driven pulley 502 and another interlocking pulley 503 form a group of movable pulleys. The slider 8 is used to keep the distance between the two groups of movable pulleys unchanged.

[0042] The two groups of movable pulleys are connected by a cable 504, and the two ends of the cable 504 are respectively connected to the two sides inside the cavity 6. The cable 504 is sleeved on the side where the driving pulley 501 and the driven pulley 502 are away from each other, and the cable 504 is also sleeved on the side where the linkage pulley 503 is close to each other. When the driving pulley 501 rotates, the distance between the linkage pulley 503 and the driving pulley 501 in the same group will increase or decrease, and the length of the cable 504 is fixed and taut. At this time, the distance between the driven pulley 502 and the linkage pulley 503 in the same group will decrease or increase accordingly, thereby realizing the operation of moving and controlling the slider 8.

[0043] The electrical components appearing in this article are all connected to an external main controller and 220V AC power, and the main controller can be a conventional known device that controls a computer, etc. The specific implementation method of the present disclosure omits the detailed description of known functions and known components. To ensure the compatibility of the equipment, the operating methods used are consistent with the parameters of marketed equipment.

[0044] Although the embodiments of the present invention have been shown and described, it will be appreciated by those skilled in the art that various changes, modifications, substitutions and variations may be made to the embodiments without departing from the principles and spirit of the present invention, and that the scope of the present invention is defined by the appended claims and their equivalents.
