[0028] 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.

[0029] Reference Figure 1 - Figure 2 , Figure 4 The utility model provides an embodiment: a novel formwork support device for highway bridge construction, including a cylinder 1. The cylinder 1 is a prior art, through which the height of the support assembly 3 can be controlled, and it can be implemented by technicians in this field. Since it is a prior art, it will not be described in detail in this case. The lower surface of the cylinder 1 is fixedly connected to a base 2, and the upper surface of the cylinder 1 is provided with a support assembly 3. The inner wall of the base 2 is provided with a rectangular groove 5, and the inner wall of the base 2 is provided with a moving assembly 4. The support assembly 3 includes a support shell 31, which is fixedly connected to the upper surface of the cylinder 1. The inner wall of the support shell 31 is slidably connected to an extension plate 32, and the connection distance between the extension plate 32 and the support shell 31 can be controlled to be adjusted at will, so as to achieve the purpose of adjusting the support surface and improve practicality. The lower surface of the support shell 31 is fixedly connected to a rectangular plate 33.

[0030] Reference Figure 1 , Figure 4 The moving component 4 includes a rotating rod 42, which is rotatably connected to the top of the inner wall of the base 2. A motor 41 is fixedly connected to the right surface of the rotating rod 42. The motor 41 is in the prior art and can be implemented by technicians in this field. Since it is a prior art, it will not be described in detail in this case. The motor 41 is fixedly connected to the right surface of the base 2, and an extrusion plate 43 is fixedly connected to the outer wall of the rotating rod 42. The inner wall of the bottom end of the extrusion plate 43 is rotatably connected to a roller 44. The roller 44 can reduce the friction when the extrusion plate 43 squeezes the connecting plate 46, thereby ensuring that the connecting plate 46 can be pushed to move smoothly.

[0031] Reference Figure 1 - Figure 2 The support assembly 3 also includes a concave block 37, which is fixedly connected to the bottom end of the right surface of the rectangular plate 33. The inner wall of the concave block 37 is hinged with a rectangular shell 34, and the inner wall of the rectangular shell 34 is slidably connected with a rectangular bar 35. The connection distance between the rectangular shell 34 and the rectangular bar 35 can be adjusted at will, and the connection distance between the support shell 31 and the extension plate 32 can be adjusted by adjusting the connection distance. The top of the rectangular bar 35 is hinged with a concave block 36, and the upper surface of the concave block 36 is fixedly connected to the right end of the lower surface of the extension plate 32.

[0032] Reference Figure 2- Figure 3 A plug rod 38 is slidably connected to the front surface of the rectangular shell 34, and a groove is opened on the front surface of the rectangular bar 35 in multiple groups. The plug rod 38 is adapted to the groove to ensure the stability of the connection. The rear surface of the plug rod 38 contacts the inner wall of the groove. A spring 39 is sleeved on the outer wall of the plug rod 38. The spring 39 always pulls the plug rod 38 backward through its own elasticity to ensure that when the plug rod 38 is not pulled, its rear surface always contacts the inner wall of the groove to ensure the stability of the connection. One end of the spring 39 is fixedly connected to the front surface of the rectangular shell 34, and the other end of the spring 39 is fixedly connected to the rear surface of the plug rod 38.

[0033] Reference Figure 1 , Figure 4 The inner wall of the rectangular groove 25 is elastically connected with the slide plate 45 through the spring 248. The spring 248 itself has a certain elasticity, and it always pulls the slide plate 45 upward through its own elasticity, ensuring that when the extrusion plate 43 releases the extrusion of the connecting plate 46, the spring 248 can pull the slide plate 45 to quickly return to the inner wall of the base 2 through its own elasticity. The right end of the slide plate 45 is slidably connected to the inner wall of the rectangular groove 25, one end of the spring 248 is fixedly connected to the inner wall of the rectangular groove 25, and the other end of the spring 248 is fixedly connected to the slide plate The upper surface of the right end of 45 and the lower surface of the skateboard 45 are provided with rollers, and the rollers can improve the flexibility of the device. The rear surface of the skateboard 45 is fixedly connected with a connecting plate 46, and a rectangular groove 47 is opened on the upper surface of the connecting plate 46. When the extrusion plate 43 squeezes the connecting plate 46 into the inner wall of the rectangular groove 47, when the connecting plate 46 keeps a vertical state, the front surface of the bottom end of the extrusion plate 43 will contact with the front end of the inner wall of the rectangular groove 47 to ensure the stability of the extrusion, and the roller 44 rolls on the inner wall of the rectangular groove 47.

[0034] Working principle: when in use, move the device to the position where support is required, start the cylinder 1 to raise the support assembly 3 to support the building. When the support area needs to be adjusted, pull the rod 38 forward to disengage the rod 38 from the inner wall of the groove. At the same time, the rod 38 will stretch the spring 1 39, and then adjust the connection distance between the rectangular shell 34 and the rectangular bar 35. During the adjustment process, the top end of the rectangular bar 35 will rotate with the concave block 1 36, and the bottom end of the rectangular shell 34 will rotate with the concave block 2 37. At the same time, the connection distance between the extension plate 32 and the support shell 31 will change, and the support area will also change accordingly. After the adjustment is completed, loosen the rod 38, and the spring 1 39 will pull the rod 38 in the direction of movement through its own elasticity, so that the rod 38 is inserted into the inner wall of the groove, so that the extension plate 32 can be supported and fixed, thereby improving stability.

[0035] When in use, the position of the device can be adjusted by the provided roller. When it needs to be parked, the motor 41 can be started, and the motor 41 drives the rotating rod 42 to rotate, and the rotating rod 42 drives the extrusion plate 43 to rotate. At this time, the roller 44 will roll on the inner wall of the rectangular groove 47 until it is separated from the inner wall of the rectangular groove 47. At the same time, the spring 48 will pull the slide plate 45 upward through its own elasticity, and the slide plate 45 will simultaneously drive the connecting plate 46 and the roller to move upward together, and the base 2 will fall under gravity and contact the ground. In this way, the process of parking the device can be completed. When it needs to be moved, the motor 41 is started to drive the rotating rod 42 to reverse, and the subsequent structural coordination method is the same as above.

[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.
