Detailed Description
The invention is further illustrated below with reference to the figures and examples.
As shown in fig. 1 to 5, an expandable platform includes a basic platform 1, where the basic platform 1 of the present application is a regular octagonal structure, or a regular polygonal structure with more than eight sides, so that the basic platform 1 is closer to a circular platform. As shown in fig. 1 to 3 and 5, a rectangular groove 1-1 symmetrical with respect to eight corners (the intersection point of every two adjacent sides of the base table 1 is called as a corner) of the base table 1 is provided. All be equipped with rotary table face I2 on each straight flange of basic mesa 1, rotary table face I2 is articulated fixedly with the straight flange of basic mesa 1, specifically, articulates fixedly rotary table face I2 and the straight flange of basic mesa 1 through round pin axle I7, and rotary table face I2 can rotate round pin axle I7. Each rectangular groove 1-1 is internally provided with a rotary table surface II 3, the rotary table surface II 3 is hinged and fixed with the rectangular groove 1-1, specifically, the rotary table surface II 3 is hinged and fixed with the rectangular groove 1-1 through a pin shaft II 8, and the rotary table surface II 3 can rotate around the pin shaft II 8. The rotary table surface I2 and the rotary table surface II 3 are both of symmetrical structures, and specifically, as shown in fig. 1 and fig. 3 to fig. 5, the table surface width of the rotary table surface I2 is gradually increased outwards from one side of the base table surface 1 (namely, the whole structure of the rotary table surface I2 is in an isosceles trapezoid shape, and the smaller end of the rotary table surface I2 is hinged and fixed with the base table surface 1). As shown in fig. 1 and 3 to 5, the inner table surface of the rotary table surface ii 3 close to the base table surface 1 is a rectangular table surface matched with the rectangular groove 1-1, and the inner table surface of the rotary table surface ii 3 is mainly used for realizing that the rotary table surface ii 3 is hinged and fixed with the base table surface 1 in the rectangular groove 1-1. The outer table top at one side, far away from the base table top 1, of the rotary table top II 3 is also a rectangular table top, and the width of the outer table top of the rotary table top II 3 is larger than that of the inner table top of the rotary table top II 3. The outer table surface of the rotary table surface II 3 and the inner table surface of the rotary table surface II 3 are in gradual transition from the middle table surface of the rotary table surface II 3 (namely the middle table surface of the rotary table surface II 3 is also in an isosceles trapezoid shape). The purpose of the outer surface of the rotary table II 3 not having the gradually increasing structure as the rotary table I2 is to prevent the rotary table II 3 from interfering with the rotary table I2 on both sides when it is folded (not unfolded). In order to prevent the interference phenomenon when two adjacent rotary table tops I2 are folded (not unfolded), chamfers or fillets are arranged on two sides of the end part of one side, far away from the base table top 1, of each rotary table top I2.
A sliding table 4 in a polygonal structure is arranged on one side of the base table top 1 (namely, the sliding table 4 is arranged on one side of the non-working surface of the base table top 1), a linear telescopic assembly is arranged between the sliding table 4 and the base table top 1 (the linear telescopic assembly is driven by an actuating mechanism which can provide linear motion, such as an oil cylinder and an electric cylinder), and the sliding table 4 is superposed with the symmetrical central axis of the base table top 1. The side of the sliding table 4 is provided with a connecting seat, and the non-working faces of the rotary table face I2 and the rotary table face II 3 are also provided with connecting seats. The corresponding connecting seats of the sliding table 4 are hinged and fixed with the corresponding connecting seats of the rotary table surface I2 through a connecting rod I5, and the corresponding connecting seats of the sliding table 4 are hinged and fixed with the corresponding connecting seats of the rotary table surface II 3 through a connecting rod II 6. As shown in fig. 1 and 2, when the linear telescopic assembly is in a contracted state, the rotary table surface i 2 and the rotary table surface ii 3 are both in an expanded state, the working surface of the rotary table surface i 2 and the working surface of the rotary table surface ii 3 are both flush with the working surface of the base table surface 1, and the expanded rotary table surface i 2 and the expanded rotary table surface ii 3 expand the approximately circular platform into an approximately circular platform with a larger area. As shown in fig. 3 to 5, when the linear expansion assembly is in the extended limit state (the limit state may be a distance that can be reached by the limit travel position of the linear expansion assembly or the linear expansion assembly can only move to the distance through the control element, i.e. stop motion is achieved), both the rotary table top i 2 and the rotary table top ii 3 are in the vertical state with respect to the base table top 1, and the linear expansion assembly extends out to retract the originally extended approximately circular platform into a smaller approximately circular platform (i.e. a state of retracting to the base table top 1).
Can set up fixed guardrail at basic mesa 1, rotatory mesa I2 sets up folding guardrail with rotatory mesa II 3 to security when improving the operation.
The device can expand the approximately circular platform into an approximately circular platform with a larger area, and can also retract the originally expanded approximately circular platform into a smaller approximately circular platform to complete the designated operation or function. Compared with the prior art, the device has the advantages of compact structure, few driving mechanisms, no steps and larger diameter of the expandable circle.
