Description

Technical Field

[0001] The utility model relates to the technical field of concrete construction, in particular to a UHPC concrete vibrating and leveling device. Background Art

[0002] UHPC concrete, short for ultra-high performance concrete, is a new type of cement-based composite material with ultra-high mechanical properties and durability, as well as good toughness, bonding properties, and impact and fatigue resistance. Wall panels in prefabricated buildings are sometimes constructed using this mix. When building wall panels, concrete is pre-placed inside a frame-shaped formwork, and then a vibrator is inserted into the concrete. The vibrator is driven by a motor to vibrate and compact the concrete.

[0003] During the actual construction process, workers control the insertion depth of the vibrator in the concrete based on their own experience. The vibration depth cannot accurately match the concrete pouring depth. Moreover, after the vibrator is inserted into the concrete, the vibrator is prone to deflection or tipping due to the vibration of the rod body itself, affecting the vibration effect. In addition, the heavy vibrator needs to be dragged manually, which is not conducive to convenient movement of the vibrator.

[0004] During the process of vibrating and compacting concrete with a vibrating rod, excess concrete will overflow from the top surface of the frame formwork. Workers usually use a scraper to directly scrape off the excess concrete on the surface of the wall panel. The scraped concrete is not convenient to collect and transport for reuse, and manually using a scraper to level the concrete is inefficient. Utility Model Content

[0005] In order to overcome the above-mentioned technical problems, the purpose of the utility model is to provide a UHPC concrete vibrating and leveling device, in which a carrier plate moves a movable plate horizontally, and the movable plate moves multiple vibrating rods longitudinally, so as to facilitate the vertical vibration and compaction of concrete in different areas, thereby improving the efficiency of concrete vibration and compaction. The feed support shell moves along the concrete surface to scrape off and collect excess concrete, and the shaft drives the propeller blades to rotate to transport the collected concrete in a direction, thereby improving the efficiency of concrete leveling and facilitating the collection of concrete.

[0006] The purpose of the utility model can be achieved through the following technical solutions:

[0007] A UHPC concrete vibrating and leveling device comprises a frame-shaped formwork, a carrier plate is provided on the top of the frame-shaped formwork, two supporting legs are fixed at both ends of the carrier plate, a vibrating mechanism is provided on the top of the carrier plate, the vibrating mechanism comprises a movable plate, a plurality of connecting pipes are evenly inserted and fixed on the bottom surface of the movable plate, a vibrating rod body is fixed on the bottom surface of the connecting pipe, both ends of the carrier plate are rotatably connected to a screw rod screwed together with the movable plate, a leveling mechanism is provided at the bottom of the carrier plate, the leveling mechanism comprises a feeding support shell, a sealing block is fixed at one end of the feeding support shell, a feeding assembly arranged inside the feeding support shell is rotatably connected to the middle part of the sealing block, a support ring 1 and a support ring 2 are respectively rotatably connected at both ends of the feeding support shell, and a motor 3 for driving the feeding support shell to rotate is fixed on the bottom surface of the carrier plate.

[0009] Furthermore, motors 1 for driving the corresponding screw rods to rotate are fixed at both ends of the bottom surface of the carrier plate, connecting blocks are fixed at both ends of the bottom surface of the carrier plate, and the support ring 1 and the support ring 2 are fixedly connected to the corresponding connecting blocks respectively.

[0010] Furthermore, a transmission ring is fixedly sleeved on one end of the feed support shell, an arc-shaped rack is fixed on the outside of the transmission ring, a support plate fixedly connected to motor three is fixed on the bottom surface of the carrier plate, and a gear meshing with the arc-shaped rack is fixed on the output end of motor three.

[0011] Furthermore, the feeding assembly includes a shaft rod rotatably plugged into the sealing block, a propeller blade is fixed to the outer side of the shaft rod, and a motor 2 for driving the shaft rod to rotate is fixed to one side of the sealing block.

[0012] Furthermore, a support tube fixedly connected to the sealing block is sleeved on the outer side of the second motor, the support tube is rotatably connected to the second support ring, and a long wedge-shaped block is fixed on one side of the open end of the feed support shell.

[0013] Furthermore, the bottom ends of the support legs are rotatably connected to rollers, wherein a chassis is fixed to the bottom ends of the two support legs, and a driving motor for driving the rollers at corresponding positions to roll is fixed inside the chassis.

[0014] Beneficial effects of the utility model:

[0015] 1. The motor drives the screw to rotate, so that the movable plate screwed with it moves down with multiple connecting pipes, and the connecting pipes move down with multiple vibrating rods and vertically insert them into the concrete, so as to prevent the vibrating rods from vibrating the concrete crookedly and affecting the vibration effect. Driven by the vibrating motor, the multiple vibrating rods vibrate and compact the concrete inside the concrete, and the depth to which the vibrating rods are inserted into the concrete is precisely driven by the screw, which is conducive to improving the efficiency of concrete vibration. In addition, the reverse rotation of the screw can move the vibrating rods up and away from the concrete, and then the vibrating rods can automatically move to different areas for vibration as the carrier plate moves, eliminating the need for manual dragging of the vibrating rods.

[0016] 2. The carrier plate drives the feeding support shell to move on the top surface of the frame formwork. The wedge-shaped block on the feeding support shell can move along the surface of the concrete to level the vibrated concrete. During the leveling process, the open end of the feeding support shell can store excess concrete. When the excess concrete needs to be transported out, the motor three drives the gear to rotate so that the transmission ring drives the feeding support shell to rotate 90 degrees, so that the collected concrete falls to the inner bottom of the feeding support shell. Then, the motor two drives the shaft to rotate so that the propeller blades rotate so that the excess concrete can be directionally transported along one end of the feeding support shell, thereby realizing automatic leveling of the concrete and collecting the excess concrete at the same time.
