DETAILED DESCRIPTION

[0027] In order to enable those skilled in the art to better understand the solution of the present application, the technical solution in the embodiments of the present application will be clearly and completely described below in conjunction with the drawings in the embodiments of the present application. Obviously, the described embodiments are only part of the embodiments of the present application, not all of the embodiments. Based on the embodiments in the present application, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of this application.

[0028] The embodiment of the present application provides a linkage lifting device, which can solve the problem in the related art that the operation is cumbersome and the safety risk is high when the operator picks up the items.

[0029] See also Figures 1 to 4 , an embodiment of the present application provides a linkage lifting device, which includes: a working platform 1, a movable fence assembly 3, a material elevator 4 and a controller 5, wherein the working platform 1 is provided with a material conveying port; the movable fence assembly 3 includes a driving member fixed to the working platform 1 and a movable fence body 30 arranged at the material conveying port, the driving member is connected to the movable fence body 30, and is used to drive the movable fence body 30 to move relative to the working platform 1 to control the opening or closing of the material conveying port; the material elevator 4 is arranged on one side of the working platform 1; the controller 5 is connected to the driving member and the material elevator 4; wherein the movable fence body 30 and the material elevator 4 are configured as follows: when the movable fence body 30 moves relative to the working platform 1 to open the material conveying port, the material elevator 4 rises to a first position, and when the movable fence body 30 moves relative to the working platform 1 to close the material conveying port, the material elevator 4 descends to a second position, and the first position is higher than the second position.

[0030] In the present application, by setting a movable fence body 30 to cooperate with the controller 5 to control the driving member and the material elevator 4, it can be achieved that when the movable fence body 30 moves relative to the working platform 1 to open the material conveying port, the material elevator 4 rises to the first position, and when the movable fence body 30 moves relative to the working platform 1 to close the material conveying port, the material elevator 4 descends to the second position, thereby ensuring the safety of personnel on the aerial work platform 1 to the greatest extent and providing convenience for the operators to take and place parts.

[0031] Among them, the controller 5 is provided with a first button and a second button. When the first button is pressed, the movable fence body 30 moves relative to the working platform 1 to open the material conveying port, and the material elevator 4 rises to the first position; when the second button is pressed, the movable fence body 30 moves relative to the working platform 1 to close the material conveying port, and the material elevator 4 descends to the second position.

[0032] When the operator stands on the work platform 1 and needs parts, he presses the first button on the controller 5, and the material elevator 4 rises, and the materials on the material elevator 4 rise to the touchable range of the operator. At the same time, the movable fence body 30 moves automatically to open the material conveying port and provide the operator with a moving channel. When the parts in the material box are used up or the material box needs to be replaced, the operator presses the second button on the controller 5, and the material elevator 4 descends, and the material box on the material elevator 4 descends. At the same time, the movable fence body 30 moves automatically to close the material conveying port to form a fence to protect the safety of the operator.

[0033] It should be noted that, in this embodiment, the first position may refer to the position of the material elevator 4 when the top surface of the material elevator 4 is flush with the working platform 1; it may also be determined based on actual conditions. When the material elevator 4 rises to the first position, there is a first distance in the height direction between the top surface of the material platform and the working platform 1. The first distance may be adjusted manually to facilitate operators standing on the working platform 1 to take parts from the material box.

[0034] The second position can be the position of the material elevator 4 when it descends to its lowest point and cannot move further downward; it can also be the position of the material elevator 4 when it descends to a second distance from the ground, and the second distance can also be manually adjusted to facilitate operators to place parts on the material elevator 4 from the ground.

[0035] On the basis of the above-mentioned embodiment, in this embodiment, the movable fence assembly 3 further includes: a guide rail 31 , the guide rail 31 is fixed on the working platform 1 , and the movable fence body 30 is slidably connected to the guide rail 31 .

[0036] The movable fence body 30 can be set in a variety of ways:

[0037] In some possible embodiments, the guide rail 31 is vertically arranged; when the movable fence body 30 descends to the third position along the guide rail 31, the material elevator 4 rises to the first position, and when the movable fence body 30 rises to the fourth position along the guide rail 31, the material elevator 4 descends to the second position.

[0038] In this embodiment, since the guide rail 31 is vertically arranged, the movable fence body 30 can slide up and down along the guide rail 31.

[0039] When the movable fence body 30 is lowered to the third position, the material conveying port is opened, and the top of the movable fence body 30 can be flush with the top of the working platform 1 or lower than the top of the working platform 1, so as to facilitate the taking of parts on the material elevator 4. When the movable fence body 30 is raised to the fourth position, the material conveying port is closed, and the top of the movable fence body 30 is higher than the top of the working platform 1. The safety distance between the top of the movable fence body 30 and the top of the working platform 1 needs to be determined according to actual conditions.

[0040] In this embodiment, the length of the movable fence body 30 can be set to be the same as the length of the working platform 1;

[0041] Alternatively, the length of the movable fence body 30 is set to be smaller than the length of the working platform 1, and fixed fences 2 are fixedly connected on both sides of the working platform 1, and the material conveying port is set between the two fixed fences 2. That is to say, the movable fence body 30 is set between the two fixed fences 2, and the movable fence body 30 and the fixed fence 2 together constitute the enclosure on one side of the working platform 1. In this case, even if the movable fence body 30 is lowered to the third position to open the material conveying port, there is also a fixed fence 2 on one side of the working platform 1 as a safety protection structure to ensure the safety of the workers during operation. Therefore, in general, the setting method of setting the length of the movable fence body 30 to be smaller than the length of the working platform 1 and fixing the fixed fences 2 on both sides of the working platform 1 is the preferred setting method.

[0042] In other possible embodiments, the guide rail 31 is horizontally arranged on the working platform 1; when the movable fence body 30 moves along the guide rail 31 to open the material conveying port, the material elevator 4 rises to the first position, and when the movable fence body 30 moves along the guide rail 31 to close the material conveying port, the material elevator 4 descends to the second position.

[0043] Specifically, in this embodiment, in order to ensure the safety of the workers during operation, guide rails 31 are provided at both ends of one side of the work platform 1, and a movable fence body 30 is slidably connected to the corresponding guide rails 31. In this case, when the two movable fence bodies 30 move away from each other, the material conveying port is opened, and at the same time, the material elevator 4 rises to the first position; when the two movable fence bodies 30 move toward each other, the material conveying port is closed, and at the same time, the material elevator 4 descends to the second position.
