Description

Technical Field

[0001] The utility model belongs to the technical field of bridge manufacturing auxiliary devices, and in particular relates to an anchor hole self-adaptive centrifugal roughening device. Background Art

[0002] my country's bridge manufacturing and erection technology is at the forefront of the world. Precast beams are needed to build bridges or viaducts. Precast beams are beam sections that are cast in advance in the factory according to construction needs. The precast beams are delivered to the construction site and then hoisted and spliced ​​into shape. Since precast beams are mass-produced in factories according to standard specifications, the shape, size, specifications, strength, etc. of precast beams can be well controlled. Bridges made with precast beams have good stability, and the efficiency of bridge erection is improved due to prefabrication in advance. Anchor holes are provided on the end faces of precast beams for connecting and fixing multiple sections of precast beams. When connecting precast beams, concrete needs to be poured into the anchor holes. Since precast beams are produced by molds, the inner wall of the anchor hole is relatively smooth. In order to improve the stability of the concrete connection, it is necessary to roughen the inner wall of the anchor hole during use, that is, use a sharp tool to cut several marks on the inner wall of the anchor hole so that the concrete can be more firmly connected and attached. The traditional roughening process relies on manpower to use a cutting machine to reach into the anchor hole for cutting and roughening, which consumes a lot of manpower, and the marks left by the roughening are messy and of varying depths, and sometimes even damage the prefabricated beams; some existing automatic roughening tools have fixed sizes, and anchor holes with slightly different calibers need to be replaced with different roughening heads, which is cumbersome to replace, consuming unnecessary time and manpower, and reducing work efficiency. In addition, both manual roughening and roughening with existing roughening equipment generate a large amount of smoke and debris, which pollutes the air around the working area, and debris splashes everywhere, all of which have an impact on the health of construction workers.

[0017] Insertion: The operator stands on the workbench, adjusts the horizontal position and height by moving the telescopic base, holds the installation operation bracket, aligns the chiseling head with the anchor hole on the precast beam and pushes it in until the limit ring reaches the bottom of the anchor hole; at this time, the centrifugal chiseling arm is retracted into the chiseling head under the action of the return spring;

[0019] Dust suction: During the chiseling step, the chiseling seat is located outside the anchor hole and has a diameter larger than the anchor hole. At this time, the dust-proof brush surrounds the outer periphery of the anchor hole. The smoke and dust generated during the chiseling process and the fallen particles are blocked by the dust-proof brush and will not spread and splash around. Start the industrial vacuum cleaner and suck out the smoke and dust covered by the dust-proof brush through the dust suction pipe and the dust suction through hole, so as to further prevent the overflow of fine smoke and dust particles and improve the working environment.

[0020] The technical solution of the utility model has the following beneficial effects:

[0021] 1. The utility model uses a centrifugal chiseling arm that can be thrown out by centrifugal force to chisel the anchor hole, so that the position where the chiseling roller contacts the anchor hole depends on the inner diameter and inclination of the anchor hole, so that the device can be applied to anchor holes with various inner diameters, thereby increasing the applicability of the device. There is no need to frequently replace the chiseling head, which reduces the manpower and time costs caused by the replacement.

[0022] 2. The dust-proof brush of the utility model can cover the periphery of the anchor hole, so that the smoke and debris generated during the chiseling process can be isolated, preventing air pollution around the working area and avoiding the splashing of the chiseled debris to injure the surrounding workers.

[0023] 3. The chiseling seat of the utility model is provided with a dust suction through hole, and smoke and dust can be sucked out from the dust suction through hole through an industrial vacuum cleaner and a dust suction pipe, so as to further avoid smoke and dust overflow and cause air pollution in the working area, thereby protecting the health of the operators.

[0024] 4. The mobile telescopic base of the utility model can move in the horizontal direction and can be raised and lowered in the vertical direction, so that the operator can easily move the chiseling head to the corresponding anchor hole position without manual walking and climbing, which is convenient for chiseling operations.

[0025] 5. The double-folding boom assembly and the balance suspension device of the utility model can ensure that the user can move the chiseling head in multiple directions, and can also balance the suspension installation of the operating bracket and the chiseling head, without the need for the user to lift the chiseling head, thereby reducing the user's work intensity.
