Description

Technical Field

[0001] The utility model relates to the technical field of semi-fluid processing equipment, in particular to a leveling device. Background Technique

[0002] Precast concrete components refer to components fabricated in factories or prefabrication sites. Through pre-design and prefabrication, they have certain strength and predetermined dimensions. They are mainly composed of materials such as cement, aggregates, fly ash, and concrete additives, and are fabricated through processes such as vibration, pressing, and steam curing.

[0003] Currently, when preparing precast concrete components, concrete needs to be poured into a mold, and then the mold is vibrated by a vibrator to make the surface of the concrete flat.

[0004] A leveling device for precast concrete components with the publication number of CN211682664U in the prior art includes a frame and a track. The frame is slidably connected to the track and is placed on the side of the mold away from the fixed mold table. A guide rail is provided on the frame along the direction of the track connection. An installation plate is slidably provided on the guide rail, and a sliding mechanism is provided on the installation plate to drive the installation plate to slide along the length direction of the guide rail; a driving mechanism is provided on the installation plate, and a leveling component is provided on one side of the driving mechanism. The leveling component includes an outer housing and blades. The mold is placed on the fixed mold table, and the frame is driven by a traveling mechanism to move to the fixed mold table. After the leveling component is attached to the surface of the mold by driving a lifting rod by a motor, the rotating shaft is driven to rotate to drive the blades to rotate, and the surface of the mold is first rotated and stirred and leveled by the rotation of the blades.

[0005] This leveling device utilizes the vibration generated when the blades rotate to break up the void bubbles in the mold. However, in actual operation, the vibration effect generated when the blades rotate is limited, and it is difficult to transmit the vibration to the bottom layer of the concrete, making it difficult for the bottom layer of the concrete to be evenly dispersed, and the bubbles in the bottom layer of the concrete are also not easily discharged, affecting the compactness of the entire precast concrete component.

[0029] A transverse movement component is installed at the top of the frame 1. A first lifting component and a second lifting component are fixedly installed at the bottom of the movable end of the transverse movement component.

A sliding seat 3 is threadedly sleeved on the outer surface of the lead screw 4. Two guide rods 5 are fixedly connected together between the inner walls on both sides of the frame 1. The guide rods 5 penetrate through the sliding seat 3 and are slidably connected thereto. The motor 6 drives the lead screw 4 to rotate. The lead screw 4 drives the sliding seat 3 to move along the guide rods 5, so as to drive the first lifting component and the second lifting component to move.

[0030] The movable end of the first lifting assembly is fixedly installed with a screeding ruler 9. The first lifting assembly includes a first mounting frame 22, and the first mounting frame 22 is fixedly installed at the bottom of the sliding seat 3.

[0032] Working principle: First, place the mold 7 on the frame 1, and then the four pushing cylinders 14 operate. The pushing cylinders 14 drive the movable plate 11 to move closer to the frame 1 side, thereby driving the positioning plate 10 to move towards the frame 1 side until the four positioning plates 10 cooperate to complete the positioning of the mold 7. Then pour the concrete slurry into the mold 7. Next, the second cylinder 16 operates, and the second cylinder 16 pushes the cross bar 13 to descend. The cross bar 13 can drive the vibrating rod 2 to rise and fall through the shock absorbers 18 and the connecting plates 21 until the vibrating rod 2 is inserted into the concrete slurry. Then the motor 6 drives the lead screw 4 to rotate, and the lead screw 4 drives the sliding seat 3 to move to one side. The sliding seat 3 drives the first lifting assembly and the second lifting assembly to move to one side. The second lifting assembly drives the vibrating rod 2 to move slowly to one side through various components. After moving a certain distance, the first cylinder 23 operates, and the first cylinder 23 drives the screeding ruler 9 to descend to a set height through the connecting frame 8, so that the concrete slurry has a screeding effect during the transverse movement. When the vibrating rod 2 moves to the other end of the mold 7, the second lifting assembly controls it to be slowly withdrawn, and then the transverse movement assembly continues to drive the screeding ruler 9 to move to a set position through various components.
