[0014] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0015] Example 1:

[0016] Please see Figure 1-2 This utility model provides a technical solution: a balance beam that can quickly adjust the paving height, including a balance bar 1, mounting brackets 2 on the left and right sides of the rear side wall of the balance bar 1, four sets of sliding sleeves 6 sleeved on the outer wall of the balance bar 1, mounting blocks 7 on the front side wall of each of the four sets of sliding sleeves 6, and through holes 8 on the top of each of the four sets of mounting blocks 7. A hanger 3 is installed in the through hole 8, and an anti-slip layer 9 is provided on the inner side wall of the through hole 8. Under the action of the anti-slip layer 9, the friction between the hanger 3 and the through hole 8 can be increased, thereby improving the fixing effect of the hanger 3. A connecting bracket 5 is provided at one end of the hanger 3, and an ultrasonic probe 4 is provided on the top of the connecting bracket 5. A cavity 10 is opened inside the mounting block 7, and a fixing component 11 is provided inside the cavity 10.

[0017] Please see Figure 2The fixing component 11 includes a movable block 113 slidably connected within the cavity 10. Limiting grooves are formed on both the left and right sidewalls of the cavity 10. Limiting blocks matching the limiting grooves are also provided on the left and right sidewalls of the movable block 113. Under the action of the limiting grooves and limiting blocks, the movable block 113 moves more stably within the cavity 10. A movable rod 111 is provided on the rear sidewall of the movable block 113. A clamping plate 110 is provided within the through hole 8. One end of the movable rod 111 is connected to the outer sidewall of the clamping plate 110. A spring 112 is sleeved on the outer wall of the movable rod 111. One end of the spring 112 is connected to the rear sidewall of the cavity 10, and the other end is connected to the rear sidewall of the movable block 113. A pressing block 114 is movably connected to the front sidewall of the cavity 10. The side wall is provided with a guide groove, and the front side wall of the extrusion block 114 is provided with a guide block that matches the guide groove. Under the action of the guide groove and the guide block, the screw 115 drives the extrusion block 114 to move more stably. The right side wall of the extrusion block 114 is provided with a screw 115. One end of the screw 115 passes through the right side wall of the cavity 10 and is connected to the external adjustment knob 116. The extrusion block 114 and the movable block 113 are both set in the shape of a right trapezoid. Under the action of the guide groove and the guide block, the screw 115 drives the extrusion block 114 to move. The inclined surface of the extrusion block 114 can squeeze the inclined surface of the movable block 113. The movable block 113 squeezes the spring 112 and the movable rod 111. The movable rod 111 drives the clamping plate 110 to fix the hanging rod 3.

[0018] Working principle: The mounting frame 2 is fixed to the paver using fixing bolts. The sliding sleeve 6 can move on the balance bar 1, thereby driving the suspension rod 3 to move. The suspension rod 3 can drive the ultrasonic probe 4 to move. When the paving height needs to be adjusted, the operator pulls the suspension rod 3 upward. The suspension rod 3 drives the connecting frame 5 to move. The connecting frame 5 drives the ultrasonic probe 4 to move upward. When it reaches the appropriate position, the operator rotates the adjustment knob 116 to drive the screw 115 to rotate. Under the action of the guide groove and guide block, the screw 115 drives the extrusion block 114 to move. The inclined surface of the extrusion block 114 can extrude the inclined surface of the movable block 113. The movable block 113 extrudes the spring 112 and the movable rod 111. The movable rod 111 drives the clamping plate 110 to fix the suspension rod 3, thereby realizing the adjustment of the paving height.

[0019] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
