DETAILED DESCRIPTION
[0016] like Figure 1-Figure 15 As shown, the present invention provides a support device for a rope-driven liftable bogie, including a universal wheel 10, a base 20, a fixed column assembly 30, a movable wheel assembly 40, a movable column assembly 50, a handle 60, a wheel fixing seat 70, a worm gear transmission assembly 80, and a steel wire rope 90.
[0017] The base 20 is used for installing and fixing the column assembly 30 and the universal wheel 10 .
[0018] The fixed column component 30 is welded from profiles, and is provided with bolt holes for installing a fixed guide wheel component 1 31, a mounting seat for installing a fixed pulley 32 is welded thereto, a wire rope fixing seat 35 for installing a wire rope 90 is provided, a fixed column fixing seat 36 and a worm gear transmission component fixing seat 37 are welded at the bottom, and a fixed guide wheel component 2 33 and a worm gear transmission component 80 are respectively fixed to the fixed column component 30 by bolts.
[0019] The fixed guide wheel component 1 31 is composed of a first pulley 311, a fixed shaft 312, a bearing 313, a bearing cover 314, a fastening bolt 315, and a spacer 316; the fixed guide wheel component 2 33 is composed of a second pulley 331, a fixed shaft 332, a bearing 333, a spacer 334, a bearing cover 335, a fastening bolt 536, a shaft retaining ring 337, and a fixed seat 338.
[0020] The moving wheel assembly 40 is composed of a moving wheel 401 , a fixed shaft 402 , a bearing 403 , a bearing cover 404 , and a fastening bolt 405 .
[0021] The movable column assembly 50 is composed of an outer movable column assembly 510, an inner movable column assembly 520, and a movable guide wheel assembly 530; the outer movable column assembly 510 is welded by profiles, and is welded with a mounting seat 511 for mounting a wheel fixing seat 70, an inner movable column mounting seat 512, and a movable wheel assembly mounting seat 513, and is equipped with a handle 60 for pushing the entire device to move, and the movable wheel assembly 40 is fixed to the movable wheel assembly mounting seat 513. The inner movable column assembly 520 is welded by profiles, and includes an inner movable column fixing seat 521, a groove 522, and a movable pulley fixing seat 523, which is fixed to the outer movable column assembly 510 by bolts; the movable guide wheel assembly 530 is composed of a third pulley 531, a fixed shaft 532, a bearing 533, a spacer 534, a bearing pressure cover 535, a shaft retaining ring 536, a fastening bolt 537, and a fixing seat 538.
[0022] The wheel fixing seat 70 is composed of a profiling block 701 , a baffle 702 , and a bottom plate 703 . The baffle 702 and the profiling block 701 are welded to the bottom plate 703 .
[0023] The worm gear transmission component 80 is composed of seat bearings 801, 805, a worm 802, a worm wheel 803, a winding wheel 804, a driven shaft 806, a housing 807, a baffle 808, and a driving hand wheel 809. The winding wheel 804 and the worm wheel 803 are fixed to the driven shaft 806 by a key connection, and the driving hand wheel 809 is installed on the worm 802.
[0024] Furthermore, one end of the wire rope 90 is fixed to the wire rope fixing seat 35, and the other end is fixed to the winding wheel 804. The wire rope 90 starts from the wire rope fixing seat 35, passes through the movable guide wheel assembly 530, the fixed guide wheel assembly 1 31, the movable guide wheel assembly 530, the fixed pulley 32, the fixed guide wheel assembly 2 33, and the winding wheel 804 in sequence. The winding of the wire rope 90 between the movable pulley 530, the fixed guide wheel assembly 1 31, and the fixed pulley 32 can achieve a labor-saving effect.
[0025] Furthermore, a height scale 34 is installed on the fixed column assembly 30 for setting the lifting height of the supporting device.
[0026] Furthermore, the manually operated driving hand wheel 809 can be replaced with an electric motor drive.
[0027] When in use, first push the four rope-driven lifting bogie support devices to the specified position through the handle 60, fix them by adjusting the universal wheel 10, and manually operate the driving hand wheel 809 to adjust the four support devices to the same height respectively; then place the bogie assembly 100 on the support device. When placing the bogie assembly, it is necessary to ensure that the tread of the bogie wheel is in contact with the contour block 701 of the wheel fixing seat 70 and the wheel rim is effectively limited by the baffle 702; secondly, manually operate the driving hand wheel 809 for the four support devices at the same time. Under the drive of the driving hand wheel 809, the worm gear 100 is lifted and lowered. Rod 802 drives worm wheel 803 to transmit, worm wheel 803 drives winding wheel 804 to rotate, thereby driving the winding of wire rope 90. As wire rope 90 is wound on winding wheel 804, wire rope 90 will drive inner movable column assembly 520 to rise under the action of fixed guide wheel assembly 2 33, fixed pulley 32, movable guide wheel assembly 530, and fixed guide wheel assembly 1 31, thereby completing the lifting and lowering of supporting bogie assembly 100. Since the driving mechanism adopts worm gear transmission, and since worm gear transmission has self-locking property, the supporting device can be automatically locked when it rises to any position, which has strong safety. On the contrary, when the supporting device descends, the driving hand wheel 809 can be manually operated to rotate the driving hand wheel 809 in the opposite direction of the supporting device when it rises, and the supporting device will automatically descend to any position and automatically lock under the action of the deadweight of bogie assembly 100.
[0028] The above are only specific embodiments of the present invention, but the protection scope of the present invention is not limited thereto. Any changes or substitutions that can be easily thought of by a person skilled in the art within the technical scope disclosed by the present invention should be included in the protection scope of the present invention. Therefore, the protection scope of the present invention should be based on the protection scope of the claims.
