Description

Technical Field

[0001] The utility model relates to the field of lifts, in particular to a scissor lift. Background Art

[0002] Scissor lift is a widely used special equipment for aerial work. Its scissor-type mechanical structure makes the lifting platform have higher stability after lifting, a wide working platform and a higher carrying capacity, which makes the aerial work range larger and suitable for multiple people to work at the same time. It makes aerial work more efficient.

[0003] Scissor lifts are usually equipped with a mobile base, which is convenient for carrying around. A foldable four-corner positioning frame is also provided on the mobile base to fix the position of the equipment to prevent sliding during use.

[0004] When using a scissors lift, work is carried out after it is raised, but the working area is limited. If a short distance is to be moved left or right, it must be lowered, the four corner positioning frames must be folded, and the lifting platform is aligned with the bottom of the working position, and then the four corner positioning frames must be released again before continuing the work. This has a greater impact on work efficiency. For example, when installing hanging equipment, if the spatial span of the working area is slightly larger than the width of the lifting platform, repeated lifting and lowering are required, which is very time-consuming. Therefore, a scissors lift is proposed. Utility Model Content

[0005] The technical problem to be solved by the utility model is to overcome the defects of the prior art and provide a scissor lift which can perform a small range of left and right displacement after being raised, thereby increasing the working area, reducing the number of repeated lifting times, and improving work efficiency.

[0009] A driving motor is fixedly arranged on the left side of the left vertical plate, a threaded rod penetrating the left vertical plate is fixedly arranged on the output end of the driving motor, the other end of the threaded rod is rotatably connected to the right vertical plate, the external thread of the threaded rod is connected to a movable plate, the top of the movable plate is detachably provided with a bottom bracket, and the bottom bracket is used to support the lift body;

[0010] The protection platform is provided with an electromagnetic contactor, which is electrically connected to the drive motor and is used to control the switch of the drive motor and control the forward or reverse rotation of its output shaft.

[0011] As a preferred technical solution of the utility model, the front and back sides of the vertical plate are fixedly provided with positioning members, and the positioning members include a connecting plate, a threaded sleeve, an adjusting screw and a foot pad, wherein:

[0012] A connecting plate is fixed on the vertical plate;

[0013] A threaded sleeve is fixed to the end of the connecting plate away from the vertical plate;

[0014] An adjusting screw is inserted from the top of the threaded sleeve to the bottom of the threaded sleeve and is threadedly connected with the threaded sleeve;

[0015] The foot pad is rotatably arranged at the bottom of the adjusting screw.

[0016] As a preferred technical solution of the utility model, a slide groove is provided on the top of the horizontal plate, and a walking wheel extending into the slide groove is fixedly provided on the bottom of the movable plate.

[0017] As a preferred technical solution of the utility model, a slot is provided at the bottom of the base, and an insertion rod extending into the slot is fixedly provided at the top of the movable plate.
