Description

Technical Field

[0001] The utility model belongs to the technical field of crane transportation, and particularly relates to a crane anti-seismic transportation frame device. Background Art

[0002] A crane refers to a multi-action lifting machine that vertically lifts and horizontally transports heavy objects within a certain range. A winch is a light and small lifting device that winds a wire rope or chain around a drum to lift or tow a heavy object. It is also called a hoist. A winch can vertically lift, horizontally or obliquely tow heavy objects. Winches are divided into three types: manual winches, electric winches, and hydraulic winches. The electric winch is the main type. It can be used alone or as a component in machinery such as lifting, road construction, and mine hoisting. Because of its simple operation, large rope winding capacity, and convenient relocation, it is widely used. As a type of crane, the winch is widely used at construction sites because of its small volume and easy transportation. However, when a crane is generally in use, it needs to be transported to the corresponding location by a transportation device, and a transportation frame is also required to cooperate on the transportation device to make it transported stably. However, some existing transportation frames often still have certain deficiencies when in use, so it needs to be improved.

[0003] In the Chinese patent with the publication number CN218464262U, a transportation frame is mentioned, which includes a bottom frame. Vertical rods are connected to both sides of the bottom frame, and a first cross beam and a second cross beam parallel to each other are installed on the vertical rods; a U-shaped support plate is installed on the side of the first cross beam facing the bottom frame, and a support block is placed inside the U-shaped support plate, and the support block is fixed to the U-shaped support plate by screws; on the side of the second cross beam facing the bottom frame, parallel inserted plates are installed, and the parallel inserted plates are inserted into both sides inside a U-shaped stopper, and the U-shaped stopper is fixed to the second cross beam by screws. In the structure of the utility model, by providing support and limit for the support block and the U-shaped stopper through the U-shaped support plate and the inserted plates respectively, while increasing the support strength of the support block and the U-shaped stopper, the stability of the workpiece placed on the transportation frame is increased, and it can be avoided that the support block and the U-shaped stopper are deformed under pressure and cannot be used. While increasing the service life of the support block and the U-shaped stopper, the overall use cost is reduced.

[0004] However, although the above technical solution can achieve the purpose of conveying objects when in use, the sizes and positions of the internal support blocks and U-shaped stoppers are relatively fixed when in use. At this time, it will make it difficult to convey some larger objects. Because the sizes of the support blocks and U-shaped stoppers are fixed and the internal support space is limited, objects larger than the internal support space are difficult to be stuck into the inside of the support blocks and U-shaped stoppers. As a result, some objects with larger or smaller volumes are difficult to be stably conveyed inside the transportation frame, so it has certain limitations when in use. Summary of the Utility Model

[0005] The purpose of the present utility model is to provide a seismic transportation frame device for a crane, so as to solve the problem that it is difficult to adjust according to the size of the object to be transported during the use of the transportation frame, resulting in a relatively single object being transported when transporting objects, as proposed in the above background technology.

[0023] Embodiment 1:

[0024] Please refer to Figure 1 、 Figure 2 、 Figure 3 and Figure 5 As shown, a seismic transport frame device for a crane includes a fixed bottom plate 1. A bearing frame 2 is fixedly connected to the top of the fixed bottom plate 1. Positioning frames 3 are fixedly connected to both sides of the top of the bearing frame 2.

Two connecting rods 18 are fixedly connected to the surface of the threaded sleeve 17. Through the setting of the threaded rod 16 and the threaded sleeve 17, the two connecting rods 18 can move downward. It should be noted that the end of the connecting rod 18 away from the threaded sleeve 17 is slidably connected to the inner side wall of the pressing plate 6, ensuring that the up and down movement of the threaded sleeve 17 plays a certain guiding and limiting role.

[0026] A second electric telescopic rod 20 is fixedly connected to the surface of the connecting rod 18. Vertical grooves 19 are formed at the top ends of both sides of the surface of the pressing plate 6. The output end of the second electric telescopic rod 20 is fixedly connected to a connecting block 21. Through the setting of the second electric telescopic rod 20, the connecting block 21 can move forward. It should be noted that the pressing plates 6 are grouped in pairs and have the same internal structure, and the directions in which every two second electric telescopic rods 20 face are opposite.

[0027] The bottom of the connecting block 21 is fixedly connected with a contraction cylinder 22. The inner top wall of the contraction cylinder 22 is fixedly connected with a first shock-absorbing spring. The bottom end of the first shock-absorbing spring is fixedly connected with a first damping block. The bottom of the first damping block is fixedly connected with a first extrusion rod 23. The bottom end of the first extrusion rod 23 is fixedly connected with a first extrusion cross plate 24.

Through the arrangement of the second extrusion rod 26 and the second extrusion cross plate 27, the second shock-absorbing spring and the second damping block can be extruded.

[0029] Embodiment Two:

[0030] Please refer to Figure 1 and Figure 4 As shown, eleven groups of first electric telescopic rods 10 are fixedly connected to the inner bottom wall of the fixed bottom plate 1. The output ends of the first electric telescopic rods 10 are fixedly connected with a lifting plate 11. Eight positioning brackets 12 are fixedly connected to the top of the lifting plate 11. A roller 13 is rotatably arranged inside the positioning bracket 12 through a rotating shaft. The bottom end of the inner side wall of the bearing frame 2 is fixedly connected with a cross beam 14. A number of through holes 15 are formed inside the cross beam 14, and the surface of the roller 13 penetrates through the inside of the through holes 15. Through the arrangement of the first electric telescopic rods 10, the lifting plate 11 can move upward by a certain distance. Through the arrangement of the positioning brackets 12, they can move upward together with the lifting plate 11, so that the roller 13 passes through the inside of the through holes 15. Through the arrangement of the roller 13, it is convenient to slightly move the crane when the bottom of the crane contacts the cross beam 14, facilitating the adjustment of the position.

[0031] Working principle of the utility model: The staff pre-fixes the fixed bottom plate 1 on the transportation equipment. Subsequently, the staff hoists the winch by a hoisting device, then moves it above the device and positions it between two adjacent pressing plates 6. Then, the staff can adjust the falling orientation according to the falling position of the winch until the bottom of the winch touches the cross beam 14. During this process, the staff can start the first electric telescopic rod 10. The output end of the first electric telescopic rod 10 drives the lifting plate 11 to rise. Subsequently, the lifting plate 11 drives the positioning bracket 12 to rise, so that the positioning bracket 12 drives the roller 13 to rise until it passes through the inside of the through hole 15. After the winch falls, it contacts the surface of the roller 13. At this time, the staff can finely adjust the position of the winch on the cross beam 14 through the roller 13. Then, the staff moves the two pressing plates 6 so that the second pressing cross plate 27 presses the front and back surfaces of the winch. When the pressing plate 6 moves, the sliding block 5 slides inside the sliding groove 4. Until the two second pressing cross plates 27 press the winch, at this time, the staff inserts the insertion rod 9 into the first positioning hole 8 inside the support cross plate 7 and the second positioning hole inside the sliding block 5, so that the two adjacent pressing plates 6 are fixed. Then, the staff can rotate the threaded rod 16. The rotation of the threaded rod 16 drives the threaded sleeve 17 to descend, so that the threaded sleeve 17 drives the connecting rod 18 to descend. Subsequently, the connecting rod 18 drives the second electric telescopic rod 20 to descend. During the descending process, the staff can control the second electric telescopic rod 20 to work, so that the two first pressing cross plates 24 facing each other in the adjacent two pressing plates 6 move forward. Finally, the staff continues to rotate the threaded rod 16, so that the threaded sleeve 17 descends, so that the bottom of the first pressing cross plate 24 contacts the top of the winch and presses it. In case of subsequent bumps and left-right shaking, the first shock-absorbing spring and the first damping block absorb the up-and-down vibrations, and the second shock-absorbing spring and the second damping block absorb the force of the front-and-back shaking, ensuring the stability of the winch inside the overall device. After the winch is stably placed, at this time, the staff can control the first electric telescopic rod 10 to retract, so that the roller 13 enters the inside of the fixed bottom plate 1 for storage, and the bottom of the winch fully contacts the cross beam 14.
