[0024] The following will be combined with the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the embodiments described are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0025] Example 1

[0026] like Figures 1 to 3As shown, this embodiment proposes a concrete paving structure for road and bridge construction, including a symmetrically arranged frame 1 and connecting columns 3, the outer surface of the frame 1 is fixedly connected to a fixed bracket 2 and a power box 4, the outer surface of the frame 1 is rotatably connected to a stirring roller 5, a promotion structure 7 is provided between the end of the stirring roller 5 and the frame 1, and a locking structure 8 is provided between the connecting column 3 and the fixed bracket 2; the outer surface of the stirring roller 5 is fixedly connected to a stirring blade 6, the outer surface of the frame 1 is rotatably connected to a flattening roller 9, a synchronous motor is provided inside the power box 4, and a transmission belt 10 is wound around the output shaft of the synchronous motor and the outer surface of the flattening roller 9 through a pulley, a group of synchronous motors respectively drives a group of stirring rollers 5 or flattening rollers 9 to rotate, the transmission belt 10 for driving the stirring roller 5 to rotate is an elastic belt, the number of stirring blades 6 is two groups and they are symmetrically distributed, and the stirring blades 6 are a spiral structure.

[0027] The promoting structure 7 includes a fixed column 71 fixedly connected to the outer surface of the frame 1, and a card slot 72 is provided at the lower end of the fixed column 71. A push spring 73 is provided inside the card slot 72, and the lower end of the push spring 73 is connected to a sliding column 74. A connecting seat 75 is provided between the lower end of the sliding column 74 and one end of the stirring roller 5. A fixing plate 77 is fixedly connected to the outer surface of one side of the fixed column 71 near the upper end of the stirring roller 5, and a convex ball 76 is fixedly connected to the lower end of the fixing plate 77 on the outer surface of the stirring roller 5.

[0028] The fixing column 71 is fixed to the frame 1 by welding, and the sliding column 74 slides up and down inside the slot 72. The connecting seat 75 and the sliding column 74 are fixedly connected, and the end of the stirring roller 5 and the connecting seat 75 are rotatably connected by a bearing; the fixing plate 77 is fixed to the fixing column 71 by welding, and the number of convex balls 76 is several groups, and several groups of convex balls 76 are distributed in a ring array on the outer surface of the stirring roller 5; the pushing spring 73 is vertically arranged, and the upper and lower ends of the pushing spring 73 are fixedly connected to the fixing column 71 and the sliding column 74 respectively. The maximum outer diameter of the rotation of the convex ball 76 will interfere with the fixed plate 77, and the maximum interference distance is two-thirds of the radius of the convex ball 76. The vibration is generated in the process of rotating the stirring roller 5 by the convex ball 76 hitting the fixed plate 77.

[0029] In this embodiment, when in use, the frame 1 moves to one side, driving the entire structure to move together. The synchronous motor and the transmission belt 10 drive the stirring roller 5 and the flattening roller 9 to rotate respectively. First, the concrete is combed by the rotation of the stirring roller 5 together with the stirring blade 6. During the rotation of the stirring roller 5, the convex ball 76 will hit the fixed plate 77. Under the action of the sliding column 74, the fixed column 71 and the push spring 73, the connecting seat 75 can be moved up and down, generating a certain vibration. Therefore, the stirring roller 5 and the stirring blade 6 generate a certain vibration during the rotation, which can further cause the concrete to generate a certain vibration, ultimately making the paved concrete better and faster in molding, and improving the construction efficiency.

[0030] During the process of the mixing roller 5 rotating to comb and balance the concrete, the vibration effect can be increased, and the mixing roller 5 and the stirring blade 6 can vibrate up and down at the same time during the rotation, thereby accelerating the stabilization of the concrete, forming a horizontal effect more quickly, and promoting the paving effect of the concrete.

[0031] Example 2

[0032] like Figure 4 As shown, on the basis of Example 1, a locking structure 8 is further proposed, which includes a slide groove 81 opened on the outer surface of the fixed bracket 2, and a connecting hole 85 is opened on the outer surface of the fixed bracket 2 near the end. A reset spring 82 is arranged inside the slide groove 81, and one end of the reset spring 82 is connected to a movable column 83. The outer surface of the lower end of the fixed bracket 2 is fixedly connected to a limiting plate 84 near the connecting hole 85, and a locking hole 86 is opened on the outer surface of the connecting column 3.

[0033] The card hole 86 allows one end of the movable column 83 to pass through from the inside. The movable column 83 is a regular quadrangular prism structure. The movable column 83 is pushed by the return spring 82 to achieve one end of the movable column 83 fitting with the outer surface of the limit plate 84; the diameter of the connecting hole 85 matches the diameter of the connecting column 3, and the lower end of the fixed bracket 2 is connected and fixed to the frame 1 by bolts. The return spring 82 is arranged horizontally, and the elastic ends of the return spring 82 are fixedly connected to the movable column 83 and the fixed bracket 2 respectively.

[0034] In this embodiment, when connecting the connecting column 3 and the fixed bracket 2, the user can first grasp the movable column 83 and move it toward the side of the return spring 82 until the upper end of the movable column 83 is no longer in contact with the opening of the connecting hole 85. During this process, the return spring 82 will be compressed. Then, one end of the connecting column 3 is inserted downward corresponding to the position value of the connecting hole 85 until the position of the locking hole 86 corresponds to one end of the movable column 83. After that, the user leaves the movable column 83. Under the action of the return spring 82, the movable column 83 is pushed so that one end of the movable column 83 is pushed. Insert the movable post 83 into the inside of the clamping hole 86 until one end of the movable post 83 is in contact with the limit plate 84. During use, the connecting post 3 will pull the fixed bracket 2 to move horizontally. During the whole process, the connecting post 3 mainly pulls the fixed bracket 2 to operate. The movable post 83 is almost free of force. Under the action of the return spring 82, the connecting post 3 can be prevented from falling off from the fixed bracket 2. When it needs to be disassembled, it is only necessary to move the movable post 83 toward the return spring 82 again until the end is completely disengaged from the inside of the clamping hole 86. Then, move the connecting post 3 vertically upward to separate. It is extremely convenient and quick.

[0035] During use, the connection between the connecting column 3 and the fixed bracket 2 can be more convenient, and the stability of the connection between the fixed bracket 2 and the connecting column 3 can be maintained during movement, and the practical effect is strong.

[0036] The above are only preferred embodiments of the present invention and are not intended to limit the present invention. Any modifications, equivalent replacements, improvements, etc. made within the spirit and principles of the present invention should be included in the scope of protection of the present invention.
