Description

Technical Field

[0001] The utility model relates to the technical field of production of concrete track concrete slabs, in particular to a track slab round hole trimming tool. Background Art

[0002] The concrete track concrete slab is about 0.288 meters thick, 1.2 meters wide and 2.72 meters long. Its concrete strength is C60, which is about twice the strength of ordinary concrete products. This type of track concrete slab weighs about 2.5 tons. During the production process, due to factors such as transportation, vibration, high-temperature steam curing, acid and alkali corrosion of seals, deformation, etc., the holes and ends of the track concrete slabs that come into contact with the track concrete slab tooling will inevitably leak. Because the production cost of a track concrete slab is high, it cannot be scrapped because of some defects, especially some holes with a large dimensional tolerance range. Therefore, it is very meaningful to make a tooling that can repair the holes of the track concrete slab.

[0003] Currently, the water drill cutters on the market are all cylindrical in shape. The cutter and guide rod are made into one piece and have specific specifications. The cutting edge cannot be replaced. Once the cutter is worn, it can only be replaced as a whole. Not only is the cost of use high, it is also not suitable for cutting high-strength concrete such as track concrete slabs. Summary of the invention

[0004] The utility model aims to provide a track plate circular hole trimming tool to solve the above-mentioned defects caused by the prior art.

[0005] The track plate circular hole trimming tool comprises an equipment base, a bracket is arranged directly above the equipment base, a lifting mechanism is arranged on the outer side of the bracket, the lifting mechanism dynamically adjusts the height of the trimming tool according to the height of the track concrete plate, and improves the flexibility of vertical trimming of the track concrete plate, one side of the bracket is bolted to a side support arm, one side of the side support arm is provided with a trimming mechanism, the trimming mechanism trims the circular holes on the surface of the track concrete plate, and its components are disassembled and replaced according to the trimming requirements.

[0006] Preferably, the lifting mechanism includes a side guide seat, a spur gear, a gear, a side positioning seat and an electric cylinder. The side guide seat is arranged through the outside of the bracket, the internal shaft of the side guide seat is connected with a gear, a spur gear is welded on one side of the bracket, one end of the outer side of the side guide seat is connected to the side positioning seat, the bottom end of the side positioning seat is connected to the output end of the electric cylinder, and the electric cylinder is installed on one side of the equipment base.

[0007] Preferably, the side positioning seat is meshingly connected with one side of the spur gear bar via a gear disposed inside.

[0010] Preferably, the side guide seat is connected to the output end of the electric cylinder via a side positioning seat connected to one side.

[0011] Compared with the prior art, the utility model has the following advantages:

[0012] 1. The cutter disc of the guide rod is made into an inverted cone shape. The inverted cone shape is conducive to the grinding block to smoothly cut into the hole with a small amount of cutting when working. There is a gap between the grinding blocks, which is conducive to chip removal; the number of diamond grinding blocks is increased to 8, which increases the cutting edge and reduces the wear of the tool; the diamond grinding block is fixed on the guide disc with bolts, and the grinding block is easy to replace after wear.

[0013] 2. The inverted cone shape is conducive to the smooth cutting into the hole with a small amount of cutting when the grinding block is working.
