Example 4
The embodiment is a further improvement on the basis of embodiment 3, and the improved lifting platform is structurally shown in fig. 6 and 7.
In the process that the platform rises from bottom to top, the scissor-type lifting platform in the prior art often needs larger power to lift the platform during primary lifting, the force required by lifting is gradually reduced along with the lifting of the platform, when the traditional hydraulic cylinder is used for providing power for the platform, a larger power motor and a larger-size hydraulic cylinder are often needed, and meanwhile, the lifting speed of the whole platform is not uniform during the lifting process. In order to change the above situation, the embodiment provides a lifting platform, which includes a base 1-2, a platform 1-1, a worm screw lifter 1-3, and a scissor type lifting device; the scissor type lifting device is arranged between the base 1-2 and the platform 1-1, the screw rod 1-4 of the turbine screw rod lifter 1-3 moves vertically, and the turbine screw rod lifter 1-3 is positioned around the platform 1-1.
When the platform lifting device is used, when the platform 1-1 is not lifted, the screw rod 1-4 of the worm gear screw rod lifter 1-3 is in contact with the base 1-2, when the platform 1-1 is lifted, the driving shaft of the worm gear screw rod lifter 1-3 drives the nut matched with the screw rod 1-4 to rotate, so that the screw rod 1-4 is displaced in the vertical direction, the platform 1-1 is supported by the screw rod 1-4 to be lifted, and then the platform 1-1 is continuously lifted by using the scissor type lifting device. The embodiment uses a worm gear screw lifter 1-3 to assist the scissor type lifting device, thereby reducing the requirements on the hydraulic cylinder. The length of a screw rod 1-4 of the turbine screw rod lifter 1-3 is smaller than the highest lifting distance of the scissor type lifting device. The reason for setting the length of the screw rod in this way is on the one hand energy saving. In the initial stage of lifting, the force required by lifting by using the scissor type lifting device is larger than the force required by using the turbine screw rod lifting machine 1-3, so that the turbine screw rod lifting machine 1-3 is used for lifting for a certain distance, and the scissor type lifting device can normally work, and at this time, the turbine screw rod lifting machine 1-3 does no work if continuing to work. Meanwhile, if only the worm screw lifter 1-3 is used, the vertical screw 1-4 cannot keep the platform 1-1 stable, and the screw 1-4 deforms. On the other hand, the problem that the screw rods 1-4 are easy to bend due to too long screw rods 1-4 can be avoided, and the service lives of the screw rods 1-4 are guaranteed.
Preferably, the scissor type lifting device comprises double scissor arms 1-5; the double-scissor-fork arm 1-5 comprises a first connection inflection point 1-8, a gearbox 1-6 is arranged on the first connection inflection point 1-8, and the gearbox 1-6 is further connected with a driving screw rod 1-7 of the scissor type lifting device.
The double-scissor-arm 1-5 connection is formed by matching two cross-shaped scissor arms, the connection point of the two cross-shaped scissor arms is a connection inflection point, one end of a driving screw 1-7 of the scissor type lifting device is fixedly connected with a first connection inflection point 1-8, the driving screw 1-7 of the scissor type lifting device is driven by force to pull the first connection inflection point 1-8, and a platform 1-1 connected with the scissor type lifting device is lifted, and the mode of controlling the driving screw 1-7 of the scissor type lifting device is various, can be controlled by a hydraulic cylinder and can also be controlled by a motor.
Preferably, the double-scissor arm 1-5 further comprises a second connection inflection point 1-9, the second connection inflection point 1-9 is fixedly connected with a buffer nut 1-10, and the buffer nut 1-10 is sleeved on a rod body of a driving screw 1-7 of the scissor type lifting device and is in sliding connection with the rod body of the driving screw 1-7 of the scissor type lifting device. The buffer nuts 1-10 have the following functions: in the initial lifting stage, the worm gear lead screw lifter and the scissor type lifting device work simultaneously, but the lifting rates of the worm gear lead screw lifter and the scissor type lifting device are different, and in the initial stage, the lifting rate of the scissor fork arm is greater than the lifting rate of a lead screw of the worm gear lead screw lifter, so that the scissor fork mechanism is provided with the buffer nuts 1-10 to adjust the lifting rates of the worm gear lead screw lifter and the scissor type lifting device.
The above description is only a preferred embodiment of the present invention, and is not intended to limit the scope of the present invention.
