Description

Technical Field

[0001] This utility model relates to the field of lifting platform technology, and in particular to a movable lifting platform. Background Technology

[0002] Lifting platforms are used for lifting and raising heavy objects. Scissor lifts are typically used for loading and unloading trucks, raising goods to the same height as the truck bed to facilitate pushing or pushing them in or out. Lifts replace manual labor and can carry very heavy items for transport, making them particularly important in cargo transportation.

[0003] In the prior art, application CN202220320796.9 provides a movable scissor lift platform, including a fixed base and a wheel device. The wheel device is rotatably installed at the bottom of the fixed base. The wheel device includes a wheel base plate rotatably installed on both sides of the bottom of the fixed base. A load-bearing bracket is rotatably installed on one side of the wheel base plate, and a moving wheel is rotatably installed at the bottom of the load-bearing bracket via a load-bearing shaft.

[0004] In the aforementioned lifting platforms, the scissor lift uses a two-sided support method to lift and lower goods. This means that the other two sides of the goods are not supported, resulting in uneven force distribution on the goods. This can easily cause instability during lifting and lowering, posing a significant safety risk. Utility Model Content

[0005] The purpose of this invention is to address the shortcomings of existing technologies by proposing a movable lifting platform.

[0006] To achieve the above objectives, the present invention adopts the following technical solution:

[0007] A movable lifting platform includes a base, with rollers installed at the four corners of the lower surface of the base, a push rod fixed to the upper surface of the base, a lifting plate arranged above the base, an anti-slip pad fixed in the middle of the upper surface of the lifting plate, and railings evenly fixed to the sides of the upper surface of the lifting plate. A transmission mechanism and a lifting mechanism are provided between the lifting plate and the base.

[0008] Using the above technical solution, an anti-slip pad is fixed in the middle of the upper surface of the lifting platform, and railings are evenly fixed on the sides of the upper surface of the lifting platform to prevent goods from slipping.

[0009] Preferably, the transmission mechanism includes a protective cover, which is fixedly connected to the base. A motor is fixed to the inner wall of the protective cover, and an output shaft is installed at the output end of the motor. A first bevel gear is fixed at the end of the output shaft.

[0010] Preferably, the first bevel gear is meshed with four second bevel gears, the four second bevel gears are coaxially fixed with a drive shaft, and the drive shaft is movably connected to the base. The other end of the drive shaft is fixed with a third bevel gear, and the third bevel gear is meshed with a fourth bevel gear.

[0011] Using the above technical solution, the motor drives multiple transmission shafts to rotate simultaneously through the output shaft, the first bevel gear, and the second bevel gear. A third bevel gear is coaxially fixed at the other end of the transmission shaft. The third bevel gear meshes with a fourth bevel gear fixed on the threaded rod, so that the four lifting mechanisms operate simultaneously.

[0012] Preferably, the lifting mechanism includes a threaded rod, which is movably connected to the base and coaxially fixedly connected to the fourth bevel gear. The threads on both sides of the threaded rod are in opposite directions, and two sliders are symmetrically threaded to the outer side of the threaded rod. Both sliders are provided with a first guide rail, which is fixedly connected to the base. A first shaft barrel is movably mounted on both sliders.

[0013] Preferably, a shear bar is movably installed on the outer side of the first shaft barrel, and the shear bar is symmetrically distributed between the base and the lifting plate. A second shaft barrel is movably installed at the middle position of the shear bar, and a second guide rail is slidably connected to the top of the shear bar.

[0014] Using the above technical solution, after the threaded rod rotates, multiple sets of shear bars provide force to the lifting plate. The four sides of the lower surface of the lifting plate are simultaneously subjected to an upward force, which lifts the lifting plate and the goods, ensuring that the goods are lifted and lowered smoothly.

[0015] This utility model has the following beneficial effects:

[0016] The transmission mechanism drives multiple lifting mechanisms, which are evenly distributed on the four sides of the bottom surface of the lifting platform. When goods are placed on the lifting platform, the multiple lifting mechanisms work together to lift the platform and the goods, ensuring that the goods are lifted and lowered smoothly. An anti-slip pad is fixed in the middle of the upper surface of the lifting platform to reduce the chance of the goods slipping. Attached Figure Description
