Description

Technical Field

[0001] The utility model relates to the technical field of concrete vibration, in particular to a concrete vibration device for building construction. Background Technique

[0002] Concrete vibration is a process of eliminating air bubbles and tamping concrete. When pouring concrete components with a concrete pouring machine, it is necessary to remove the air bubbles and tamp the concrete to make the concrete densely combined, eliminate phenomena such as honeycombing and pitting on the concrete surface, so as to improve its strength and ensure the quality of concrete components.

[0003] After retrieval, a concrete vibration device for building construction disclosed in a Chinese patent with the publication number CN213297180U includes a machine body. A motor is fixedly connected to the rear side wall of the inner cavity of the machine body. A rotating shaft is provided at the output end of the motor. An incomplete gear is fixedly sleeved on the outer surface of the rotating shaft. The incomplete gear meshes with a rack; when the incomplete gear meshes with the rack, the rack is driven to move downward, the second spring is compressed, the bottom of the counterweight loses the support of the rack and moves downward, and the first rack is stretched; when the incomplete gear does not mesh with the rack, the rack is driven to move upward under the reset action of the second spring. When the rack pushes the counterweight upward, the counterweight will also give the rack a downward force, so that the descending time of the rack is much less than the ascending time, so that the vibration head inserts quickly and pulls out slowly, so as to avoid leaving voids in the concrete and achieve a better vibration effect. The technical key point lies in: controlling the speed when the vibration head is pulled out.

[0004] The above solution solves the problem of the relatively fast pulling-out speed of the vibration head. However, in the actual use process, since two springs are used to control the rack to reset, when the rack moves upward, the first spring at the top will apply an upward pulling force to the rack, so that the upward reset speed of the rack is still relatively fast, affecting the vibration quality of the concrete.

[0005] Therefore, a new solution needs to be proposed to solve this problem. Content of the Utility Model

[0006] Aiming at the deficiencies and defects in the prior art that the moving-out speed of the vibration head from the concrete is relatively fast in the above-mentioned background technique.

[0007] The concrete vibrating device for building construction disclosed by the utility model includes a machine case. Two groups of rollers are fixedly connected to the bottom surface of the machine case. A square cylinder is fixedly connected to the inner bottom wall of the machine case. A piston plate is slidably connected to the inner wall of the square cylinder. A push block is slidably connected to the inner wall of the square cylinder. The bottom surface of the push block is fixedly connected to the upper surface of the piston plate. A push plate is fixedly connected to the upper surface of the push block. A rotary vibrating motor is fixedly connected to the bottom surface of the push plate. The output end of the rotary vibrating motor is fixedly connected to a connecting shaft. A through hole is formed in the inner bottom wall of the machine case. The bottom end of the connecting shaft penetrates through the through hole and extends below the through hole. A vibrating head is fixedly connected to the bottom end of the connecting shaft. A bearing is fixedly embedded in the inner side wall of the machine case. A driving motor is fixedly connected to the inner side wall of the machine case. The output end of the driving motor is fixedly connected to a connecting rod. The right end of the connecting rod is fixedly connected to the inner ring of the bearing. An eccentric wheel is fixedly connected to the outer surface of the connecting rod.

[0008] By adopting the above scheme, the eccentric wheel can push the push plate to move downward, so that the push block pushes the piston plate to move downward. The piston plate presses the gas inside the square cylinder and also pushes the rotary vibrating motor to move downward, so that the vibrating head moves downward and inserts into the concrete. As the eccentric wheel rotates, the push block moves upward by the thrust of the gas to reset the push plate, and then the vibrating head can be reset.

[0009] Optionally, two positioning rings are fixedly connected to the outer surface of the connecting rod. The left and right side surfaces of the eccentric wheel are respectively in contact with the mutually approaching side surfaces of the two positioning rings.

[0010] By adopting the above scheme, the eccentric wheel is positioned by the positioning rings, the stability of the eccentric wheel is increased, and the eccentric wheel is prevented from sliding.

[0011] Further, two groups of sliding rods are slidably connected to the inner wall of the push plate. The bottom end of each sliding rod is fixedly connected to the inner bottom wall of the machine case, and the top end of each sliding rod is fixedly connected to the inner top wall of the machine case.

[0012] By adopting the above scheme, the push plate can be guided by the sliding rods to prevent the sliding rods from tilting.

[0013] Further, a sealing ring is fixedly connected to the outer surface of the push block. The bottom surface of the sealing ring is in contact with the upper surface of the piston plate.

[0014] By adopting the above scheme, the sealing effect of the piston plate can be enhanced by the sealing ring, and the phenomenon of air leakage during the working process can be prevented.

[0015] Further, a group of ventilation openings are formed in both the front and back of the machine case, and a control panel is fixedly connected to the upper surface of the machine case.

[0016] By adopting the above solution, the air inside the device can be made to flow through the ventilation openings, preventing heat from accumulating inside the equipment.

[0017] Furthermore, two limiting plates are fixedly connected to the inner wall of the chassis, and both of the two limiting plates are located above the push plate.

[0018] By adopting the above solution, the push plate can be limited by the limiting plates to prevent the push plate from colliding with the driving motor.

[0019] Furthermore, a control handle is provided on the right side of the chassis, and the left side surface of the control handle is fixedly connected to the right side surface of the chassis.

[0020] By adopting the above solution, the control handle can facilitate the pushing of the device for movement and can also pull the device to adjust its direction.

[0021] Compared with the prior art, the beneficial effects of the present utility model are as follows:

[0022] 1. The present utility model can provide power to the connecting rod through the driving motor, enabling the connecting rod to control the rotation of the eccentric wheel. The rotation of the eccentric wheel can push the push plate to move up and down, and then the push plate can push the vibrating motor and the vibrating head downward, enabling the vibrating head to vibrate the concrete. At the same time, the air inside the square tube is squeezed by the push block and the piston plate, so that after the eccentric wheel pushes the push plate downward, the piston plate can control the push block and the push plate to slowly reset, thereby avoiding the vibrating head from moving out of the concrete too quickly and ensuring the vibrating effect on the concrete.

[0023] 2. The present utility model enables the device to move through the rollers, and the push plate can be guided by the sliding rod to ensure that the push plate remains stable during movement. The ventilation openings can allow air to enter the interior of the chassis, so that the heat inside the chassis can be discharged, avoiding the interior of the chassis from being in a high-temperature state for a long time.
