Description

Technical Field

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

[0002] A scissor lift, also known as a scissor-lift platform, is a type of lifting and loading equipment widely used in industrial and commercial fields. Its core structure is the scissor lift (scissor boom), which raises and lowers the platform through the crisscrossing extension and retraction of multiple scissor lifts. During operation, a hydraulic system typically provides power to extend and retract the scissor lifts. As the scissor lifts, the platform rises; as it retracts, the platform lowers.

[0003] In actual use, the platform will be driven upward to a suitable position, and then the workpiece can be placed on the platform (at this time, the platform will drop a very small distance). After that, the workpiece can be processed. After processing is completed, the workpiece can be removed (at this time, the platform will rise a very small distance). Understandably, this will cause the lifting platform to be inaccurate in positioning and the workpiece to get stuck when entering and exiting. Utility Model Content

[0020] This utility model embodiment provides a lifting platform, such as Figure 1 , Figure 2 and Figure 3 As shown, it includes: The system comprises a base 1, a platform 2 mounted on the base 1, and a scissor fork 3 positioned between the platform 2 and the base 1. The base 1 is provided with a slide rail 12 extending in the left-right direction. The lower right end of the scissor fork 3 is connected to the base 1, and the upper left end is capable of sliding along the slide rail 12. The platform 2 is provided with a locking device 4. When the upper left end of the scissor fork 3 moves to a preset position to the right, the locking device 4 locks the upper left end of the scissor fork 3 in the preset position.

[0021] Here, when the upper left end of the scissor fork 3 slides to the right along the slide rail 12, the table 2 moves upward; when the upper left end of the scissor fork 3 slides to the left along the slide rail 12, the table 2 moves downward. When the upper left end of the scissor fork 3 is locked in the preset position, the table 2 cannot move up or down. This ensures precise positioning of the lifting platform and prevents jamming when workpieces enter or exit.

[0022] In this embodiment, as Figure 2 and Figure 3As shown, the locking device 4 includes: a fixing block 41 and a horizontal telescopic rod 42. A through hole is provided on the fixing block 41. The horizontal telescopic rod 42 extends in a left-right direction and passes through the through hole. The upper left end of the scissor fork 3 can drive the horizontal telescopic rod 42 to move to the left by moving to the right, and the upper left end of the scissor fork 3 can drive the horizontal telescopic rod 42 to move to the right by moving to the left. A vertical rod 43 is provided on the left side of the fixing block 41, and the lower end face of the vertical rod 43 is an inclined surface sloping upwards to the right. The left side of the horizontal telescopic rod 42... A protrusion 421 is provided at the end, and the right side of the protrusion 421 is a vertical plane; the vertical rod 43 and the horizontal telescopic rod 42 can be in a first state and a second state; the first state is that the lower end face of the vertical rod 43 abuts against the upper surface of the protrusion 421; the second state is that the left side face of the vertical rod 43 abuts against the right side face of the protrusion 421; when the vertical rod 43 and the horizontal telescopic rod 42 are in the first state, and the horizontal telescopic rod 42 moves to the left, finally, when the vertical rod 43 and the horizontal telescopic rod 42 are in the second state, and a part of the horizontal telescopic rod 42 is on the right side of the fixing block 41.

[0023] Here, the horizontal telescopic rod 42 can move left and right relative to the fixed block 41. The lower end face of the vertical rod 43 is an inclined plane that slopes upward to the right, making the transition from the first state to the second state smoother.

[0024] Initially, the vertical rod 43 and the horizontal telescopic rod 42 are in the first state. When the table 2 moves upward, the upper left end of the scissor fork 3 moves to the right, which drives the horizontal telescopic rod 42 to the left. At this time, the vertical rod 43 and the horizontal telescopic rod 42 are in the second state (at this time, the table moves upward to the appropriate position). It can be understood that since the right side of the protrusion 421 is a vertical plane, and the left side of the vertical rod 43 abuts against the right side of the protrusion 421, when a workpiece is placed on the table 2, due to the vertical rod 43... When the left side of 3 abuts against the right side of the protrusion 421, the table 2 cannot move downwards. At this time, because part of the horizontal telescopic rod 42 is on the right side of the fixed block 41, the table 2 can still rise a certain distance. When the workpiece is removed from the table 2, the table 2 can still rise a certain distance due to the elastic force. The upper end of the left side of the scissor fork 3 can drive the horizontal telescopic rod 42 to move a certain distance to the right when it moves to the left. However, if a workpiece is placed on the table 2, the table 2 can still return to the appropriate position.

[0025] In this embodiment, as Figure 2 and Figure 3 As shown, the protrusion 421 and the left end of the horizontal telescopic rod 42 are connected by a flexible member 424. In actual use, the protrusion 421 and the vertical rod 43 will collide, therefore, the flexible member 424 can greatly buffer the impact force.

[0026] In this embodiment, as Figure 2 and Figure 3 As shown, a first spring 431 is fitted onto the vertical rod 43, and the first spring 431 applies a downward force to the vertical rod 43. The first spring 431 applies a downward force to the vertical rod 43, thereby ensuring that the vertical rod 43 and the horizontal telescopic rod 42 are firmly in the second state.

[0027] In this embodiment, as Figure 2 and Figure 3 As shown, a second spring 422 is fitted on the horizontal telescopic rod 42, and the second spring 422 applies a force to the right to the horizontal telescopic rod 42.

[0028] In this embodiment, as Figure 2 and Figure 3 As shown, the protrusion 421 is conical, with the tip of the cone pointing to the left. This conical shape facilitates a smoother transition from the first state to the second state.

[0029] In this embodiment, as Figure 2 and Figure 3 As shown, the locking device 4 further includes a rotating shaft 441 and a rotating rod 442. The rotating shaft 441 is fixedly connected to the table surface 2. The rotating rod 442 can rotate around the rotating shaft 441. The first end of the rotating rod 442 is connected to the upper left end of the scissor fork 3, and the second end is connected to the right side of the horizontal telescopic rod 42. The first and second ends are two opposite ends of the rotating rod 442. Here, the rotating shaft 441 and the rotating rod 442 cooperate with each other so that the upper left end of the scissor fork 3 moving to the right can drive the horizontal telescopic rod 42 to the left, and the upper left end of the scissor fork 3 moving to the left can drive the horizontal telescopic rod 42 to the right. Here, the second end is connected to the horizontal telescopic rod 42 by a rod whose length can be changed.

[0030] The city is under construction, such as Figure 3 As shown, the rotating rod 442 is provided with a waist hole 4421. The length direction of the waist hole 4421 is the same as the extension direction of the rotating rod 442. The rotating shaft 441 is inserted into the waist hole 4421.

[0031] In this embodiment, as Figure 3 As shown, the distance between the first end and the pivot is greater than the distance between the second end and the pivot. In practice, the left-right movement of the upper left end of the scissor fork 3 is very large, and the distance between the first end and the pivot is greater than the distance between the second end and the pivot, thus reducing the left-right movement of the horizontal telescopic rod 42.

[0032] In this embodiment, as Figure 2 and Figure 3As shown, a stop 423 is provided at the right end of the horizontal telescopic rod 42, and the stop 423 cannot pass through the through hole.

[0033] It should be understood that although this specification describes embodiments, not every embodiment contains only one independent technical solution. This way of describing the specification is only for clarity. Those skilled in the art should regard the specification as a whole. The technical solutions in each embodiment can also be appropriately combined to form other embodiments that can be understood by those skilled in the art.

[0034] The detailed descriptions listed above are merely specific descriptions of feasible implementations of this utility model, and are not intended to limit the scope of protection of this utility model. All equivalent implementations or modifications made without departing from the spirit of this utility model should be included within the scope of protection of this utility model.
