[0023] In order to make the purpose and technical solution of the utility model clearly and completely described, and the advantages more clearly understood, the embodiments of the utility model are further described in detail in conjunction with the accompanying drawings. It should be understood that the specific embodiments described here are part of the embodiments of the utility model, not all of the embodiments, and are only used to explain the embodiments of the utility model, and are not used to limit the embodiments of 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] Embodiment 1

[0025] See also Figure 1-Figure 5 The utility model provides a technical solution: a large gantry crane with a wind and rainproof structure, the large gantry crane comprising: a frame 1, a base 2 is installed at the bottom of the frame 1, a roller 3 is installed at the bottom of the base 2, a plurality of symmetrically placed deep grooves 5 are opened at the bottom of the base 2, a support assembly 6 is installed inside the deep groove 5, and a storage box 4 is installed on the top of the frame 1;

[0026] When in use, the frame 1 of the crane moves on the track through the rollers 3 under the base 2. When encountering strong winds, the crane is prevented from shaking. The stability of the crane is enhanced by the support assembly 6 at the bottom of the base 2. By increasing the gripping area of ​​the base 2, the rollers 3 are prevented from slipping, thereby improving the stability of the crane. At the same time, by using the rainproof cloth 20 in the storage box 4, the entire crane can be covered when it rains heavily to prevent the crane from being eroded by rain water.

[0027] Embodiment 2

[0028] On the basis of the first embodiment, in order to facilitate the movement of the bottom plate 7 and the specific support of the crane by the support assembly 6, the support assembly 6 includes a bottom plate 7, the bottom plate 7 is located on the side wall of the deep groove 5 and is placed flush with the side wall of the base 2, the side wall of the bottom plate 7 is installed with a support rod 8, the support rod 8 is located inside the deep groove 5, and a connecting rod 9 is installed between the support rods 8. The connecting rod 9 can flexibly connect multiple support rods 8 together to facilitate the synchronous movement of the bottom plate 7 on the same side. The center of the outer surface of the connecting rod 9 is installed with a rotating shaft 11, and the rotating shaft 11 facilitates the movable clamping rod 10 to move to the outside of the deep groove 5 and be fixed on the base 2 When the side wall of the base 2 is rotated, the connecting rod 9 is driven to rotate so that the several supporting rods 8 and the bottom plate 7 are synchronously rotated and supported on the ground. The outer surface of the rotating shaft 11 is installed with a movable clamping rod 10, and the upper end of the movable clamping rod 10 is penetrated and installed with a screw rod 13. The lower end of the movable clamping rod 10 is penetrated and installed with a limit rod 12. The limit rod 12 prevents the movable clamping rod 10 from rotating and moving along the outer surface of the screw rod 13 when the screw rod 13 rotates. Both ends of the limit rod 12 and the screw rod 13 are installed with a limit shaft 14, which is located inside the base 2. The limit rod 12 and the screw rod 13 are placed in parallel and fixed inside the deep groove 5.

[0029] When in use, the screw rod 13 in the deep groove 5 on the left and right sides of the base 2 drives the movable clamping rod 10 to move under the action of the limit rod 12, and then drives the connecting rod 9 and the support rod 8 to move, so that the bottom plate 7 can be moved out from the side wall of the base 2. When the movable clamping rod 10 moves to the side wall of the base 2, the rotating shaft 11 drives the connecting rod 9 to rotate, thereby driving the support rod 8 and the bottom plate 7 to rotate, so that the bottom plate 7 rotates to the ground, which facilitates the movement of the bottom plate 7. Through multiple bottom plates 7, the base 2 is evenly supported on both sides, the gripping area of ​​the base 2 is increased, the roller 3 is prevented from slipping, and the stability of the crane is improved.

[0030] Embodiment 3

[0031] On the basis of the second embodiment, in order to facilitate the storage and release of the rainproof cloth 20 and prevent the heavy rain from corroding the crane, a storage slot 15 is opened inside the storage box 4, and driving motors 16 are installed at both ends of the storage slot 15. A gear 17 is installed at the output end of the driving motor 16, and a gear 2 18 is installed on the teeth of the gear 17. A winding drum 19 is installed through the center of the gear 2 18. The winding drum 19 is placed parallel to the inside of the storage box 4, and a rainproof cloth 20 is installed on the outer surface of the winding drum 19. The outer end of the rainproof cloth 20 passes through the notch of the storage slot 15;

[0032] When in use, when it rains, the driving motors 16 at both ends drive the gear 17 to rotate, and the gear 17 drives the gear 2 18 to rotate through the tooth engagement, thereby driving the winding drum 19 on both sides to rotate. When the winding drum 19 rotates, the release of the rainproof cloth 20 can be controlled. The rainproof cloth 20 can cover the crane, thereby preventing the crane from being corroded by heavy rain. When it is not raining, the rainproof cloth 20 can be retracted into the inside of the winding drum 19.

[0033] In actual use, the frame 1 of the crane moves on the track through the rollers 3 under the base 2. When encountering strong winds, the crane is prevented from shaking, and the stability of the crane is enhanced by the support assembly 6 at the bottom of the base 2. When the support assembly 6 is in use, the screw rods 13 in the deep grooves 5 on the left and right sides of the base 2 drive the movable clamping rod 10 to move under the action of the limit rod 12, and then drive the connecting rod 9 and the support rod 8 to move, so that the bottom plate 7 can be moved out from the side wall of the base 2. When the movable clamping rod 10 moves to the side wall of the base 2, the rotating shaft 11 drives the connecting rod 9 to rotate, thereby driving the support rod 8 and the bottom plate 7 to rotate, so that The bottom plate 7 is rotated to the ground to facilitate the movement of the bottom plate 7. Multiple bottom plates 7 are evenly supported on both sides of the base 2 to increase the gripping area of ​​the base 2, prevent the roller 3 from slipping, and improve the stability of the crane. When it rains, the driving motors 16 at both ends drive the gear 17 to rotate, and the gear 17 drives the gear 2 18 to rotate through the tooth engagement, thereby driving the winding drum 19 on both sides to rotate. When the winding drum 19 rotates, the release of the rainproof cloth 20 can be controlled. The rainproof cloth 20 can cover the crane, thereby preventing the crane from being corroded by heavy rain. When it is not raining, the rainproof cloth 20 can be retracted into the inside of the reel 19.

[0034] Although embodiments of the present invention have been shown and described, it will be appreciated by those skilled in the art that various changes, modifications, substitutions and variations may be made to the embodiments without departing from the principles and spirit of the present invention, and that the scope of the present invention is defined by the appended claims and their equivalents.
