DETAILED DESCRIPTION

[0016] The embodiment of the present application discloses an electric hydraulic support device, which drives the movable sleeve 42 to move up and down through the reciprocating screw 41, so that the hinged rod 46 drives the rotating rod 45 to rotate around the fixed rod 44, so that the rotating rod 45 drives the fixed plate 47 and the plug plate 48 to extend and retract accordingly, thereby changing the length of the fixed plate 47 and the plug plate 48 to adapt to templates of different sizes.

[0017] In order to better understand the above technical solution, the above technical solution will be described in detail below in conjunction with the accompanying drawings and specific implementation methods.

[0018] Please refer to Figure 1 The present embodiment provides an electric hydraulic jacking device, including an electric hydraulic rod 10, a fixing seat 30 is fixedly provided on the top of the electric hydraulic rod 10, through grooves 50 are provided at both ends of the fixing seat 30, and a jacking adjustment mechanism 40 is provided inside the two through grooves 50, and a support assembly 20 is fixedly provided on the outer side of the electric hydraulic rod 10, and the support assembly 20 includes a vertical upright pole 21, a diagonal brace 22, and a castor 23, four vertical upright poles 21 are all fixedly provided on the outer side of the electric hydraulic rod 10, a plurality of diagonal braces 22 are staggered between the four vertical upright poles 21, and four castor braces 23 are respectively provided on the outer sides of the four vertical upright poles 21, and the structures of the vertical upright poles 21 and the diagonal brace 22 are strengthened by the diagonal braces 22 staggered between the four vertical upright poles 21, and the castor braces 23 on the outer side of the vertical upright poles 21 support the vertical upright poles 21, so that the vertical upright poles 21 support the electric hydraulic rod 10, so that the electric hydraulic rod 10 can stably support the template.

[0019] Please refer to Figure 1 , Figure 2 and Figure 3The top support adjustment mechanism 40 includes a reciprocating screw 41, a movable sleeve 42, a limit block 43, a fixed rod 44, a rotating rod 45, a hinged rod 46, a fixed plate 47, an insert plate 48, and a driving assembly 49. The four fixed rods 44 are respectively fixed on both sides of the middle of the two through grooves 50, and the two rotating rods 45 are respectively rotatably connected to the outer sides of the two fixed rods 44 inside the same through groove. The fixed plate 47 is hinged to the top of one of the rotating rods 45, and the insert plate 48 is hinged to the top of the other rotating rod 45, and the insert plate 48 is interlaced with the fixed plate 47. The reciprocating screw 41 is rotatably connected to the bottom of the through groove 50, the movable sleeve 42 is sleeved and threadedly connected to the outer side of the top of the reciprocating screw 41, and the two hinged rods 46 are interlaced and connected to one end of the two rotating rods 45 close to the movable sleeve 42, and the two hinged rods 46 are respectively connected to the movable sleeve 42. The two sides of the movable sleeve 42 are hinged, and the middle parts of the inner walls on both sides of the through groove 50 are provided with limit grooves 60. Two limit blocks 43 are respectively arranged on the front and back sides of the movable sleeve 42. The limit blocks 43 are slidably connected to the inside of the limit grooves 60. Through the sliding of the limit blocks 43 in the limit grooves 60, the movable sleeve 42 will not rotate with the reciprocating screw 41, so that the rotation of the reciprocating screw 41 can drive the movable sleeve 42 to move up and down, so that the two hinged rods 46 hinged on both sides of the movable sleeve 42 can drive the rotating rod 45 to rotate around the fixed rod 44 with the up and down movement of the movable sleeve 42, thereby changing the distance between the tops of the two rotating rods 45, so that the fixed plate 47 and the plug plate 48 are stretched and retracted accordingly, changing the contact area between the fixed plate 47 and the plug plate 48 and the template, supporting templates of different sizes, and also improving the stability of the template support.

[0020] Please refer to Figure 1 , Figure 2 and Figure 3 The driving assembly 49 for driving the two reciprocating screws 41 to rotate is arranged inside the fixed seat 30. The bottom of the fixed seat 30 is provided with a cavity 70. The driving assembly 49 includes a sprocket 491, a chain 492, and a driving motor 493. The two sprockets 491 are respectively fixedly arranged at one end of the two reciprocating screws 41 extending into the cavity 70. The chain 492 is meshed and connected to the outside of the two sprockets 491. The driving motor 493 is fixedly installed inside the fixed seat 30, and the output shaft of the driving motor 493 is fixedly connected to one of the sprockets 491. The rotation of the driving motor 493 inside the seat 30 drives a sprocket 491 to rotate, so that the sprocket 491 drives the chain 492 meshing with it on the outside to rotate, thereby driving another sprocket 491 to rotate, so that the two reciprocating screws 41 can rotate synchronously, so that the two fixed plates 47 and the plug plate 48 can be extended and retracted synchronously, and the extension and retraction of the plug plate 48 in the fixed plate 47 can also ensure that the fixed plate 47 and the plug plate 48 are always in a horizontal position, preventing the fixed plate 47 and the plug plate 48 from tilting, thereby affecting the support effect on the template.

[0021] This application can explain its functional principle through the following operation methods:

[0022] When in use, the driving motor 493 inside the fixing seat 30 is started, so that the output shaft of the driving motor 493 drives a sprocket 491 to rotate, so that the sprocket 491 drives the chain 492 meshing with it on the outside to rotate accordingly, and the chain 492 drives another sprocket 491 meshing with it to rotate accordingly, so that the two reciprocating screws 41 can rotate synchronously, and the rotation of the reciprocating screw 41 drives the movable sleeve 42 threadedly connected thereto to move up and down accordingly, and the limiting blocks 43 on the front and back sides of the movable sleeve 42 slide inside the limiting groove 60 to limit the movement of the movable sleeve 42 and prevent the movable sleeve 42 from rotating with the reciprocating screw 41. The up and down movement of the movable sleeve 42 causes the hinged rods 46 hinged on both sides to drive the rotating rods 45 interlaced with them. Rotating around the fixed rod 44 changes the distance between the tops of the two rotating rods 45, so that the fixed plate 47 and the plug plate 48 are extended and retracted accordingly, changing the overall length of the fixed plate 47 and the plug plate 48. Since the plug plate 48 is inserted into the fixed plate 47, the fixed plate 47 and the plug plate 48 remain horizontal, preventing the fixed plate 47 and the plug plate 48 from tilting, resulting in an inability to stably support the formwork. Then, the electric hydraulic rod 10 on the inner side of the four vertical uprights 21 is started, so that the electric hydraulic rod 10 drives the fixing seat 30 to move upward to a suitable position, so that the fixed plate 47 and the plug plate 48 can support the formwork. The extension and retraction of the fixed plate 47 and the plug plate 48 can change the contact area with the formwork, thereby stably supporting formworks of different sizes.

[0023] Obviously, those skilled in the art can make various changes and modifications to the present application without departing from the spirit and scope of the present application. Thus, if these modifications and variations of the present application fall within the scope of the claims of the present application and their equivalents, the present application is also intended to include these modifications and variations.

[0024] What has been described above is only a preferred specific implementation manner of the embodiments of the present application, but the protection scope of the present application is not limited thereto. Any technician familiar with the technical field can make equivalent substitutions or changes according to the technical scheme and concept of the present application within the technical scope disclosed in the present application, which should be covered by the protection scope of the present application.
