Description

Technical Field

[0001] The utility model relates to the technical field of scissor-type lifting devices, in particular to a scissor-type lifting device with a stable structure. Background Art

[0002] Scissor lifts are widely used equipment for aerial work. However, existing scissor lifts are relatively short in width, resulting in some wobbling when raised. This lack of stability presents a safety hazard for operators working on the lifts. Summary of the Invention

[0003] The purpose of the utility model is to overcome the deficiencies of the prior art and provide a scissor-type lifting device with a stable structure to improve safety.

[0004] In order to achieve the above purpose, the utility model adopts the following technical solutions:

[0005] A scissor-type lifting device with a stabilizing structure includes a lifting body, which includes a top frame, a base and a scissor support frame. The base and the top frame are connected by a scissor support frame. The base is connected to a driver for driving the scissor support frame to lift. At least one side of the lifting body is provided with a stabilizing structure, which includes an upper cross arm, an upper stabilizing rod, a lower stabilizing rod and a lower cross arm. One end of the upper cross arm is fixedly connected to the side of the top frame, one end of the lower cross arm is fixedly connected to the side of the base, the upper end of the upper stabilizing rod is hinged to the other end of the upper cross arm by a pin shaft, the lower end of the upper stabilizing rod is hinged to the upper end of the lower stabilizing rod by a pin shaft, and the lower end of the lower stabilizing rod is hinged to the other end of the lower cross arm by a pin shaft. The stabilizing structure moves synchronously with the scissor support frame.

[0006] Furthermore, there are two stabilizing structures located on the same side of the lifting body. The two stabilizing structures are spaced apart from each other and are symmetrically arranged. The hinge point between the two stabilizing structures is located in the middle of the side surface of the lifting body.

[0007] Furthermore, the driver is an oil cylinder or a pneumatic cylinder.

[0008] Furthermore, the base is fixedly connected to the trolley.

[0009] Furthermore, stabilizing structures are provided on both sides of the lifting body.

[0010] Furthermore, one end of the upper cross arm is detachably fixedly connected to the side of the top frame, and one end of the lower cross arm is detachably fixedly connected to the side of the base; or, one end of the upper cross arm is welded and fixedly connected to the side of the top frame, and one end of the lower cross arm is welded and fixedly connected to the side of the base.

[0011] The utility model adopts the above technical solution and adds a stabilizing structure on at least one side of the lifting body. Since the stabilizing structure moves synchronously with the scissor support frame, the size of the lifting body in the width direction is increased and the strength of the mechanical structure is enhanced, thereby improving the stability of the lifting body and effectively ensuring the safety of the operators. BRIEF DESCRIPTION OF THE DRAWINGS

[0012] The present invention will be further described in detail below with reference to the accompanying drawings and specific embodiments:

[0013] Figure 1 It is a front view of the utility model;

[0014] Figure 2 It is a side view of the utility model;

[0015] Figure 3 This is a front view of the stable structure. DETAILED DESCRIPTION

[0016] like Figure 1-3 As shown, the utility model has a scissor-type lifting device with a stable structure, including a lifting body, which includes a top frame 1, a base 2 and a scissor-type support frame 3. The base 2 is connected to the top frame 1 through a scissor-type support frame. The base 2 is connected to a driver 4 for driving the scissor-type support frame 3 to rise and fall. The driver 4 can be an oil cylinder or a pneumatic cylinder.

[0017] The stabilizing structure 5 is provided on at least one side of the lifting body. This means that the stabilizing structure 5 can be provided on a single side of the lifting body or on both sides. In this embodiment, the stabilizing structure 5 is provided on both sides of the lifting body to maximize the stability of the lifting body.

[0018] Specifically, the stabilizing structure 5 includes an upper cross arm 51, an upper stabilizing rod 52, a lower stabilizing rod 53 and a lower cross arm 54. One end of the upper cross arm 51 is fixedly connected to the side of the top frame 1, and one end of the lower cross arm 54 is fixedly connected to the side of the base 2. The upper end of the upper stabilizing rod 52 and the other end of the upper cross arm 51 are hinged by a pin, the lower end of the upper stabilizing rod 52 and the upper end of the lower stabilizing rod 53 are hinged by a pin, and the lower end of the lower stabilizing rod 53 and the other end of the lower cross arm 54 are hinged by a pin. The stabilizing structure 5 moves synchronously with the scissors support frame 3.

[0019] Preferably, there are two stabilizing structures 5 located on the same side of the lifting body, the two stabilizing structures 5 are spaced apart from each other and are symmetrically arranged, and the hinge point between the two stabilizing structures 5 is located in the middle of the side of the lifting body (the opening directions of the two stabilizing structures 5 are opposite to each other).

[0020] In order to realize the movable function, the base 2 of the scissor-type lifting device of the present invention can be fixedly connected to the trolley.

[0021] In the present invention, a stabilizing structure 5 is added to at least one side of the lifting body. Since the stabilizing structure 5 moves synchronously with the scissor support frame 3, the size of the lifting body in the width direction is increased and the strength of the mechanical structure is enhanced, thereby improving the stability of the lifting body and effectively ensuring the safety of the operators.

[0022] In addition, it should be noted that the stabilizing structure in the present invention can be made into a detachable structure. Specifically, one end of the upper cross arm can be detachably fixedly connected to the side of the top frame, and one end of the lower cross arm can be detachably fixedly connected to the side of the base. The detachable connection structure can be a bolt and nut assembly or a clamping structure.

[0023] If the stabilizing structure is non-detachable, one end of the upper cross arm is fixedly connected to the side of the top frame by welding, and one end of the lower cross arm is fixedly connected to the side of the base by welding.

[0024] The above describes the specific implementation of the present invention, but those skilled in the art should understand that this is only an example. Those skilled in the art can make various changes or modifications to this implementation without departing from the principle and essence of the present invention, but these changes and modifications will fall within the scope of protection of the present invention.
