Description

Technical Field

[0001] This utility model relates to the field of vibration equipment technology, and in particular to a high-efficiency concrete vibration equipment for road and bridge construction. Background Technology

[0002] As is well known, in road and bridge construction, the strength, density, and durability of concrete structures are core elements for ensuring project quality, and concrete vibration is a crucial process that determines these properties. After concrete is poured, defects such as air bubbles and voids may exist inside. If effective vibration is not performed, it will lead to a decrease in structural strength and a decline in impermeability, and in severe cases, it may cause engineering defects, affecting the service life of roads and bridges and traffic safety. Currently, commonly used concrete vibration equipment in road and bridge construction mainly includes immersion vibrators, plate vibrators, and attached vibrators. Among them, immersion vibrators are widely used in concrete vibration operations in different parts such as beams, piers, and pavements due to their flexible operation and wide applicability. Their working principle is mostly based on the centrifugal force generated by the rotation of an eccentric block driven by a motor, which causes the vibrator to vibrate at high frequency, thereby expelling air bubbles in the concrete and making the concrete dense and bonded.

[0003] However, traditional high-efficiency concrete vibrating equipment used in road and bridge construction is usually designed as a single bar, which has a limited vibration range. For large-area and thick concrete pouring areas, it is necessary to move the vibrator multiple times to complete the vibration operation. This not only takes a long time, but may also lead to uneven concrete density due to overlapping or omissions in vibration. Therefore, technical improvements are urgently needed. Utility Model Content

[0004] The purpose of this utility model is to address the shortcomings of existing technologies by proposing a high-efficiency concrete vibrating device for road and bridge construction. When in use, this high-efficiency concrete vibrating device for road and bridge construction uses a main rod to hinge multiple support rods and is equipped with multiple sets of vibrators to effectively improve vibration efficiency. Furthermore, with the help of a servo motor, screw, and hinge rod, multiple sets of support rods can be unfolded to further expand the single vibration range, allowing the vibrators to adapt to different construction areas.

[0005] To achieve the above objectives, the present invention provides the following technical solution: A high-efficiency concrete vibrating device for road and bridge construction includes a grip, a main rod fixedly connected to the middle of the lower surface of the grip, multiple support rods hinged to the upper end of the outer wall of the main rod, a storage groove opened at the upper end of the outer wall of the main rod, a servo motor fixedly connected to the middle of the top surface of the storage groove, a screw fixedly connected to the output end of the servo motor, a threaded sleeve block threadedly connected to the outer wall of the screw, and multiple hinged rods hinged to the outer wall of the threaded sleeve block. Vibrating rods are fixedly connected to the lower ends of the main rod and the support rod. A rotary motor is fixedly connected to the middle of the inner top surface of the vibrating rod. A rotating roller is fixedly connected to the output end of the rotary motor. A protrusion is fixedly connected to the outer wall of the rotating roller.

[0006] Compared with existing high-efficiency concrete vibrating equipment for road and bridge construction, this high-efficiency concrete vibrating equipment for road and bridge construction effectively improves vibration efficiency by hinged multiple support rods to the main rod and equipped with multiple sets of vibrators. Furthermore, with the help of servo motors, screws, and hinged rods, multiple sets of support rods can be unfolded to further expand the single vibration range, allowing the vibrators to adapt to different construction areas.

[0007] Furthermore, a removable battery compartment is provided at the upper end of the grip; The above technical solution, with its detachable design, facilitates battery replacement and charging, effectively ensuring the continuous working time of the equipment.

[0008] Furthermore, the threaded sleeve is slidably connected to the inner wall of the storage groove; The above technical solution facilitates the movement of the hinge rod by using a threaded sleeve block.

[0009] Furthermore, the outer walls of the hinge rods are all hinged to the upper ends of the outer walls of the support rods; The above technical solution allows the hinged rod to be easily pushed to extend or retract the support rod.

[0010] Furthermore, a wear-resistant alloy layer is fixedly connected to the outer wall of the vibrating rod, and the thickness of the wear-resistant alloy layer is 2-5mm; By using the above technical solution, the wear resistance of the outer wall of the vibrator is enhanced. Since the vibrator needs to be in continuous contact and friction with hard concrete when vibrating concrete, the wear-resistant alloy layer can effectively reduce the wear of the vibrator, extend its service life, and reduce the maintenance cost and replacement frequency of the equipment.

[0011] Furthermore, a control button is provided on one side of the grip, and the control button is electrically connected to the servo motor and the rotary motor respectively; The above technical solution allows for easy control of the servo motor and rotary motor switches via control buttons.

[0012] Furthermore, the protrusion abuts against the inner wall of the vibrating rod; Through the above technical solution, the protrusions continuously contact and exert force on the inner wall of the vibrator, converting the rotational motion into high-frequency vibration of the vibrator. This ensures efficient and direct vibration transmission, enabling the vibrator to generate sufficient compaction force, effectively expelling air bubbles from the concrete, improving the density of the concrete, and guaranteeing the compaction effect.

[0018] Compared with existing high-efficiency concrete vibrating equipment for road and bridge construction, this high-efficiency concrete vibrating equipment for road and bridge construction uses multiple support rods 13 hinged to the main rod 12 and multiple sets of vibrating rods 3 to effectively improve the vibration efficiency. Furthermore, with the help of servo motor 21, screw 22 and hinge rod 24, multiple sets of support rods 13 can be unfolded to further expand the single vibration range, so that the vibrating rods 3 can adapt to different construction areas.

[0019] A removable battery compartment 11 is provided at the upper end of the grip 1; The detachable design facilitates battery replacement and charging, effectively ensuring the device's continuous working time.

[0021] The outer walls of the hinge rods 24 are all hinged to the upper ends of the outer walls of the support rods 13. The hinge rod 24 facilitates the expansion or contraction of the support rod 13.

[0022] The outer wall of the vibrator 3 is fixedly connected with a wear-resistant alloy layer, and the thickness of the wear-resistant alloy layer is 2-5mm; By enhancing the wear resistance of the outer wall of the vibrator 3, the wear-resistant alloy layer can effectively reduce the wear of the vibrator 3, extend its service life, and reduce the maintenance cost and replacement frequency of the equipment, since the vibrator 3 needs to be in continuous contact and friction with hard concrete when vibrating concrete.

At the same time, the rotary motor 31 drives the rotating roller 32 and the protrusion 33 to rotate. Since the protrusion 33 abuts against the inner wall of the vibrator 3, a contact force is continuously generated during the rotation, converting the rotational motion into high-frequency vibration of the vibrator 3. The vibrator 3 at the lower end of the main rod 12 and the support rod 13 work together to vibrate the concrete.
