Technical Field
[0001] This utility model relates to the field of mechanical equipment, and in particular to a traction pulley lift. Background Technology
[0002] A traction pulley scissor lift is a device that uses a pulley system and traction device to achieve lifting functions. It is commonly used in industries such as construction, mining, ports, and warehousing for transporting goods or lifting personnel. Its basic principle is that the traction system (usually an electric motor or other power source) drives the steel cable or wire rope, which transmits power through the pulley system, thereby enabling the lifting platform or cargo rack to be raised or lowered.
[0003] In order to save costs, existing traction pulley lifts usually have two load-bearing bars fixed on their lifting platform to place goods. However, since the positions of the two load-bearing bars cannot be changed, workers cannot stably place goods of different sizes, resulting in low flexibility.
[0004] Therefore, it is necessary to provide a new traction pulley lift to solve the above-mentioned technical problems. Utility Model Content
[0005] To solve the above-mentioned technical problems, this utility model provides a traction pulley lift, which solves the problem that workers cannot stably place goods of different sizes and has low flexibility because the positions of the two load-bearing bars on the lift cannot be changed.
[0006] The traction pulley lifting machine provided by this utility model includes a machine body, on which a lifting platform is slidably arranged. A through groove is opened on the surface of the lifting platform, and two movable seats are slidably arranged inside the through groove. A load-bearing rod is fixed on one side of the movable seat.
[0007] A double-ended lead screw is movably installed inside the through groove. The two ends of the double-ended lead screw pass through the two movable seats respectively, and the double-ended lead screw is threadedly connected to the movable seats.
[0008] In a preferred embodiment, the surface of the double-ended lead screw is galvanized.
[0009] In a preferred embodiment, one end of the double-ended lead screw passes through the lifting platform and is equipped with a crank.
[0010] In a preferred embodiment, an adjustment seat is movably provided on one side of the lifting platform, a column is fixed on the adjustment seat, and a lifting seat is provided above the adjustment seat, with the column penetrating through the lifting seat;
[0011] The surface of the column is provided with multiple sliding grooves, and the lifting seat is slidably connected to the sliding grooves;
[0012] A pressure plate is fixed to one side of the lifting seat via a connecting rod. A pressure spring is sleeved on the column. One end of the pressure spring is fixed to the adjusting seat, and the other end of the pressure spring is fixed to the lifting seat.
[0013] In a preferred embodiment, a stop block is installed at the top of the column, and a handle is installed on the clamping plate.
[0014] In a preferred embodiment, a bracket is installed on one side of the bottom of the machine body, and casters are movably mounted on the bracket.
[0015] The beneficial effects of this utility model are:
[0016] 1. When using this elevator, depending on the size of the goods to be transported, the operator can turn the crank to drive the double-sided screw to rotate. Under the transmission action of the double-sided screw, the two moving seats will move closer or further apart along the through groove, changing the distance between the two load-bearing rods, thus facilitating the placement of goods of different sizes and greatly improving the flexibility of this elevator.
[0017] 2. After placing the heavy object, the worker can move the pressure plate to a position level with the load-bearing rod by turning the handle. Finally, the worker can release the handle, and under the action of the pressure spring, the pressure plate will slide down the slide groove to the surface of the heavy object, improving the stability of the heavy object during transportation.
