DETAILED DESCRIPTION
[0023] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.
[0024] The utility model provides Figure 1-3 The car platform structure of an industrial heavy-duty freight elevator shown in the figure comprises a car platform body 6 and a car 4 installed on the upper end of the car platform body 6;
[0025] A main fixing frame 9 is provided on the front side of the car bottom body 6;
[0026] Auxiliary fixing frames 3 are arranged on the front side of the car bottom body 6 and on the left and right sides of the main fixing frame 9 respectively;
[0027] An upper fixed frame 1 is provided on the upper side of the car 4. When the goods need to be transferred by the freight elevator, the goods can be moved to the upper side of the car bottom body 6. Inside the car 4, after the goods are piled up on the upper side of the car bottom body 6, the driving rope on the upper side of the upper fixed frame 1 will lift the car 4 up or down to complete the transfer of the goods.
[0028] The lower end outer wall of the car bottom body 6 is equidistantly provided with a plurality of return springs 12 to maintain the balance of the car bottom body 6. When heavy goods are placed at the upper corner of the car bottom body 6, causing the car bottom body 6 to tilt, the lower return spring 12 will contract. After the gravity peak has passed, the return spring 12 will gradually reset and lift up the tilted car bottom body 6 to maintain the balance of the car bottom body 6.
[0029] like Figure 2 and Figure 4 As shown, a bottom plate 7 is fixedly connected between the lower end outer walls of the plurality of return springs 12 to limit the installation position of the return spring 12, a plurality of fixed blocks 11 are equidistantly fixedly connected to the lower end outer wall of the car bottom body 6, an upper fixed sleeve 18 is fixedly connected to the lower end outer walls of the plurality of fixed blocks 11, and a plurality of lower fixed sleeves 19 are equidistantly fixedly connected to the upper end outer wall of the bottom plate 7 to limit the installation position of the return spring 12.
[0030] The upper fixing sleeve 18 and the lower fixing sleeve 19 limit the movable space of the return spring 12 , and the fixing block 11 and the bottom plate 7 increase the stability of the return spring 12 during installation.
[0031] like Figure 2 and Figure 3As shown, a plurality of balls 13 are equidistantly arranged inside the lower end outer wall of the car bottom body 6, and a limiting sleeve 14 is arranged on the lower side of the plurality of balls 13 to limit the position of the balls 13, and a sliding rod 15 is fixedly connected to the lower end outer wall of the plurality of limiting sleeves 14, and a sliding sleeve 17 is sleeved on the lower side of the plurality of sliding rods 15 to limit the position of the sliding rod 15, and a fixing spring 16 is fixedly connected to the lower end outer wall of the plurality of sliding rods 15, and the ball 13 can rotate clockwise and counterclockwise by 360 degrees under the restriction of the limiting sleeve 14.
[0032] When the car bottom body 6 is tilted, the ball 13 will roll inside the limiting sleeve 14 following the tilted car bottom body 6 to adapt to the tilted car bottom body 6, and when stacking goods on the upper side of the car bottom body 6, the ball 13 will move downward and cause the slide bar 15 to press the fixed spring 16 downward for buffering, thereby reducing the impact force when loading goods.
[0033] like Figure 1 As shown, the upper outer wall of the car 4 is fixedly connected to the car roof 2, the lower outer wall of the main fixed frame 9 is fixedly connected to the main I-beam 10, the lower outer wall of the auxiliary fixed frame 3 is fixedly connected to the auxiliary I-beam 8, and a connecting rod 5 is fixedly connected between the main fixed frame 9 and the auxiliary I-beam 8.
[0034] The lower side of the car bottom body 6 is connected and lifted by the main I-beam 10 and the auxiliary I-beam 8 , and the connection tightness between the main fixed frame 9 and the auxiliary fixed frame 3 is increased by the connecting rod 5 .
[0035] The implementation principle of this embodiment is as follows: when it is necessary to transfer goods through the freight elevator, the goods can be moved to the upper side of the car bottom body 6, inside the car 4, and after the goods are piled on the upper side of the car bottom body 6, the driving rope on the upper side of the upper fixed frame 1 will lift the car 4 up or down to complete the transfer of goods. When heavier goods are placed in the corners on the upper side of the car bottom body 6, causing the car bottom body 6 to tilt, the lower side return spring 12 will contract. After waiting for the gravity peak to pass, the return spring 12 will gradually reset to lift the tilted car bottom body 6 to maintain the balance of the car bottom body 6.
[0036] Finally, it should be noted that the above is only a preferred embodiment of the present invention and is not intended to limit the present invention. Although the present invention has been described in detail with reference to the aforementioned embodiments, those skilled in the art can still modify the technical solutions described in the aforementioned embodiments or make equivalent substitutions for some of the technical features therein. Any modifications, equivalent substitutions, improvements, etc. made within the spirit and principles of the present invention should be included in the protection scope of the present invention.
