Description

Technical Field

[0001] The utility model relates to the technical field of bridge construction equipment, in particular to a laser roller leveling machine for a bridge deck concrete protective layer. Background Art

[0002] Bridge engineering is an important branch of civil engineering, which mainly studies the design, construction, maintenance and evaluation of bridges. Bridges are transportation facilities connecting two geographical areas and can cross rivers, canyons, roads or other obstacles. Bridge engineering involves multiple disciplines, including structural engineering, materials science, geology, geographic information systems and construction management. As an important part of transportation facilities, bridge decks have extremely high requirements on the flatness, levelness and strength of the ground.

[0003] A common construction method is to pour concrete after building the support, and then level the concrete to ensure the flatness of the bridge deck to avoid problems when it is put into use later. However, most existing bridge deck concrete protective layer construction uses vibrating beams and slurry leveling machines to pour concrete, and finally the surface is finished manually. Due to errors in multiple manual operations, poor flatness often occurs, forming puddles, and the longitudinal and transverse slopes of the bridge deck do not meet the design requirements.

[0004] In view of this, this application is hereby filed. Utility Model Content

[0028] The longitudinal section of the fixing frame 2 33 is a square ring, and fixing rods are welded on the front and rear inner walls thereof. The front and rear outer walls of the fixing frame 2 33 are fixedly connected to a horizontally arranged mounting plate 43 at one end close to the fixing frame 1 13. The front and rear outer walls of the fixing frame 1 13 are fixedly connected to a mounting plate 43 of the same structure at one end close to the fixing frame 2 33.

[0033] See also Figure 1-4 The utility model provides a technical solution: the bottom of the second fixing frame 33 is respectively close to both sides of the two ballast retaining walls 11 and is detachably connected to a bearing seat 1, a leveling roller 20 is installed in the bearing seat 1, a connecting piece 26 is fixedly connected to the center of one side wall of the leveling roller 20, a groove 1 is axially opened at the center of the side wall of the leveling roller 20 away from the connecting piece 26, a coaxially arranged connecting piece 1 25 is fixedly connected in the groove 1, and the leveling roller 20 is a hollow structure;

[0034] The second connector 26 is provided with a slot along the axial direction, and a plurality of limit blocks distributed in a ring array are provided on the outer arc wall of the first connector 25. The first connector 25 is adapted to the slot, and the second connector 26 is adapted to the first groove. When the first connector 25 is fully inserted into the second connector 26, the second connector 26 is also fully inserted into the first groove, and at the same time, the two adjacent leveling rollers 20 are tightly abutted.

[0035] The vibration mechanism in the leveling roller 20 includes an inner gear ring 21 fixedly connected to the inner wall of the leveling roller 20. The inner side of the inner gear ring 21 is meshed with two gears 22 distributed in a ring array. The two gears 22 are meshed with the same gear 2 23 on the side close to each other. The gear 2 23 is fixedly connected to the inner wall of the leveling roller 20. The gear 2 23 is coaxial with the leveling roller 20 and the inner gear ring 21.

[0036] The second gear 23 is axially fixedly connected to the first rotating shaft on one side wall near the interior of the leveling roller 20. The two first gears 22 are axially fixedly connected to the second rotating shaft on one side wall near the interior of the leveling roller 20. Two eccentric blocks 24 are fixedly connected to the outer arc wall of the second rotating shaft. The two eccentric blocks 24 are axially symmetrically arranged about the center of the interior of the leveling roller 20. The initial installation angles of the eccentric blocks 24 on the two second rotating shafts differ by 180 degrees.

[0037] An annular sliding groove 1 is provided at the center of an inner wall of the leveling roller 20 away from the gear 2 23, and a rotating part 27 is rotatably connected in the sliding groove 1. Two grooves 1 are symmetrically provided on the rotating part 27, and a bearing seat 2 is embedded in the groove 1. One end of the rotating shaft 2 away from the gear 1 22 is fixedly connected to the bearing seat 2, and the other end of the rotating shaft 1 away from the gear 2 23 is rotatably connected to the inner wall of the leveling roller 20.

[0038] It should be noted that when facing bridge deck leveling operations of different lengths, the leveling roller 20 and the second fixing frame 33 can be installed or removed to adapt to different construction environments. The first connecting piece 25 and the second connecting piece 26 facilitate the splicing of the leveling roller 20. In addition, the motor that drives the leveling roller 20 is located in the second fixing frame 33 away from the hydraulic rod 32. The bottom of the motor is fixedly connected to the second support plate, which is fixedly connected to the second fixing frame 33.

[0039] In a possible embodiment, a pulley is fixedly connected to the output end of the motor, and a pulley with the same structure is detachably connected to the side wall of the leveling roller 20. The same belt is sleeved in the wheel grooves of the two pulleys, and the pulleys do not contact the ballast retaining wall 11. In addition, due to the presence of the first connector 25 and the second connector 26, the transmission shaft of the pulley can also be set as a component with the same structure as the first connector 25. At the same time, a plurality of connecting holes are opened on the outer arc wall of the second connector 26, and bolts are used to fix the second connector 26 to the pulley to ensure reliable transmission.

[0041] When the leveling roller 20 rotates, the fixed connection between gear 2 23 and the leveling roller 20 and the inner gear ring 21 and the leveling roller 20 causes the three to rotate synchronously, thereby driving gear 1 22 to rotate around the orbit of the leveling roller 20 under the action of the inner gear ring 21, thereby driving shaft 2 to rotate, and then driving the eccentric block 24 to rotate to generate eccentric force. Since the rotation angles of the eccentric blocks 24 on the two shafts 2 differ by 180 degrees, only the force in the vertical direction is preserved during eccentric rotation, and the forces in other directions all cancel each other out.

[0042] Working principle:

[0043] The designed bridge deck elevation is input into the laser leveler 12, which sends out a signal. The laser receiver 40 installed on the equipment detects the signal and transmits it to the control system, which then adjusts the lifting and lowering of the hydraulic rod 32 on the walking wheel 31 to control the elevation of the leveling roller 20, thereby achieving precise control of the surface flatness and longitudinal slope of the concrete protective layer.
