Abstract
Claims
1. An asphalt paving grade control device, comprising: The system includes an elevation adjustment unit (1), an adjustment clamping unit (2), and a constraint clamp (3). The elevation adjustment unit (1) includes an upper plate (11), a vertical cylinder (12), an adjustment screw (13), and an elevation horizontal seat (16). The vertical cylinder (12) is fixed to the top of the upper plate (11). A fixing screw sleeve (14) is fixed to the top of the vertical cylinder (12). The adjustment screw (13) passes vertically through the fixing screw sleeve (14), and a locking nut (15) is fitted on the adjustment screw (13). The elevation horizontal seat (16) is fixedly connected to the top of the adjustment screw (13), and a slot (17) is opened on the top of the elevation horizontal seat (16). The constraint clamp (3) is set in the slot (17). The adjusting clamping unit (2) includes an L-shaped base plate (21), a screw sleeve (22), and a transverse screw (23). The L-shaped base plate (21) is symmetrically arranged on the left and right sides below the upper plate (11). The screw sleeve (22) is fixed to the top of the L-shaped base plate (21). The transverse screw (23) is installed on the bottom of the upper plate (11) through a shaft seat (24). The left and right sections of the transverse screw (23) are provided with external threads with opposite directions of rotation. Guide rods (25) are provided parallel on both sides of the transverse screw (23). The guide rods (25) are fixedly connected to the shaft seat (24). The screw sleeve (22) is threadedly connected to the transverse screw (23), and the screw sleeve (22) is also guided and sleeved on the guide rod (25).
2. The asphalt pavement paving elevation control device of claim 1, wherein The constraint clip (3) includes a clip (31) and a spring (32). An installation hole (33) is provided on the inner side wall of the slot (17). The clip (31) is elastically assembled into the installation hole (33) by the spring (32), and the outer end of the clip (31) extending out of the installation hole (33) is an arc surface.
3. The asphalt pavement paving elevation control device of claim 1, wherein, The screw sleeve (22) at the top of the L-shaped base plate (21) on the left is threaded to the external thread of the left section of the transverse screw (23), and the screw sleeve (22) at the top of the L-shaped base plate (21) on the right is threaded to the external thread of the right section of the transverse screw (23). When the transverse screw (23) rotates, it can drive the L-shaped base plates (21) on both sides to move inward or move away from each other in a synchronized manner.
4. The asphalt pavement paving elevation control device of claim 1, wherein, A rubber layer (4) is also fixed to the inner wall of the L-shaped base plate (21).
5. The asphalt paving grade control device of claim 1, wherein, The elevation horizontal base (16) is provided with positioning pointers (5) on both outer sides, and the top of the upper plate (11) is provided with marking lines (6) corresponding to the positioning pointers (5) in the horizontal direction.
