[0028] Example

[0029] like Figures 1 to 4 As shown,

[0030] A pneumatic lifting roller bed comprises a roller bed 1. A plurality of support platforms 4 are installed on the front and rear sides of the bottom of the roller bed 1. The roller bed 1 is placed on a plurality of lower support brackets 2 below.

[0031] A lifting assembly 3 is provided below the roller bed 1. The lifting assembly 3 includes a linear push mechanism 11 mounted on a linear push mounting frame 12. The driving end of the linear push mechanism 11 is connected to the linear push rod 13 on the left. An adapter block 14 is mounted on the left side of the linear push rod 13. A rack 15 is mounted on the left side of the adapter block 14. The rack 15 is mounted on the right side of the adapter block 14 via a connecting rod 24. Bearing holders 18 are mounted on both the front and rear sides of the rack 15. A bearing seat 21 is mounted on the bearing holder 18. A rotating shaft 19 is mounted between the front and rear bearing seats 21. A gear 20 is mounted in the middle of the rotating shaft 19 to match the rack 15 below. A limit stopper 8 is mounted on the outside of the rack 15.

[0032] The front and rear sides of the rotating shaft 19 are connected to the first end of the rocker arm 22, and a rocker guide wheel 23 is installed at the second end of the rocker arm 22. A traveling frame 5 is installed at the bottom of the support platform 4. A traveling groove 25 distributed along the left and right directions is provided on the inner side of the traveling frame 5, and the rocker guide wheel 23 is located in the traveling groove 25.

[0033] A limit clamping mechanism 6 is installed on both sides of the roller bed 1. The limit clamping mechanism 6 is a toggle clamp. When the slide on the roller bed 1 is working at a station, in order to prevent the slide from deviating, a limit clamping mechanism 6 is added at both ends to limit the position of the slide.

[0034] A maintenance latch 7 is also installed between the rocker arm 22 and the support platform 4. When the cylinder needs maintenance, the roller bed needs to be raised to a high position. In order to prevent personal injury caused by the sudden drop of the roller bed due to gas failure, a maintenance latch 7 needs to be added to the side of the jacking mechanism.

[0035] An upper guide bracket 9 is installed at the bottom of the roller bed 1 on one side of the lower support bracket 2. An upper guide groove distributed along the vertical direction is installed in the upper guide bracket 9. An upper guide wheel 10 is installed on the lower support bracket 2 and is located in the upper guide groove.

[0036] A guide rail 17 distributed along the left-right direction is installed below the rack 15 , and the bottom of the rack 15 is connected to the guide rail 17 below through a slider 16 .

[0037] The linear driving mechanism 11 is a cylinder, and the linear driving rod 13 is a piston rod.

[0038] A cylinder (linear propulsion mechanism 11) is used to drive the gear 20 to rotate. The gear is installed on the rotating shaft 19. The gear 20 drives the rotating rocker arm 22. The rocker arm 22 drives the roller bed 1 to lift and lower. A maintenance pin 7 is added at the lifting position to prevent the roller bed from suddenly falling due to sudden air failure.

[0039] like Figure 1Initially, the roller bed is in the low position and the cylinder is retracted. After ventilation, the linear push rod 13 is pushed out. Because the cylinder's Y-shaped joint is connected to the adapter block 14 on the slide rail, the movement of the cylinder's Y-shaped joint drives the movement of the rack 15. The gear 20 cooperates with the rack 15, and the rack 15 drives the gear 20 to rotate.

[0040] like Figure 2 When the cylinder is pushed out, the rack 15 drives the gear 20 to rotate. The gear 20 is fixed on the rotating shaft 19. There is a bearing seat 21 at each end of the rotating shaft 19. The rotation of the gear 20 drives the rotating shaft 19 to rotate. The rotation of the rotating shaft 19 drives the rocker arms 22 at both ends to rotate. The lower end of the rocker arm 22 is provided with a rocker arm guide wheel 23. The rocker arm guide wheel 23 is stuck in the driving groove 25 of the jacking mechanism. When the rocker arm 22 rotates, the position of the rocker arm guide wheel 23 rises, and the jacking mechanism is lifted upward.

[0041] The working principle of the utility model is as follows: the movement of the cylinder piston rod is used to drive the rack to move on the guide rail, the gear and rack cooperate with each other, and the rack drives the rotation of the gear. The gear is installed on the rotating shaft, and the gear drives the rotating shaft to rotate. The rocker arm that raises and lowers the jacking mechanism is also installed on the rotating shaft. The rotation of the rotating shaft drives the rocker arm to rotate, thereby also driving the jacking and lowering of the jacking mechanism.

[0042] In the description of the present invention, it should be understood that the terms "center", "longitudinal", "lateral", "up", "down", "front", "back", "left", "right", "vertical", "horizontal", "top", "bottom", "inside", "outside" and the like indicate orientations or positional relationships based on the orientations or positional relationships shown in the accompanying drawings, and are only for the convenience of describing the present invention and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, be constructed and operated in a specific orientation, and therefore cannot be understood as limiting the present invention. In addition, the terms "first", "second", etc. are only used for descriptive purposes and cannot be understood as indicating or implying relative importance or implying the number of technical features indicated. Therefore, features defined as "first", "second", etc. may explicitly or implicitly include one or more of such features. In the description of the present invention, unless otherwise specified, "multiple" means two or more.

[0043] In the description of this utility model, it should be noted that, unless otherwise expressly specified or limited, the terms "mounted," "connected," and "connected" should be understood in a broad sense. For example, they may refer to fixed connections, detachable connections, or integral connections; mechanical connections, electrical connections, direct connections, indirect connections through an intermediate medium, and internal communication between two components. Those skilled in the art will understand the specific meanings of the above terms in this utility model based on specific circumstances.

[0044] The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. It should be pointed out that ordinary technicians in this technical field can make several improvements and modifications without departing from the technical principles of the present invention. These improvements and modifications should also be regarded as within the scope of protection of the present invention.
