Abstract
Description
Technical Field
[0001] The utility model relates to construction machinery, in particular to a quick repair device for a sand and gravel filter screen. Background Art
[0002] During the construction of railways and highways, a large amount of sand and gravel is required. Crushed stone and sand are two main types of crushed stone used in road construction. Crushed stone is the backbone of various concretes. Generally speaking, gravel with a particle size of 2mm or more is called gravel, while sand with a particle size of 2.0-0.74mm is called sand. Sand is the main raw material for cement mortar, cement brown concrete, asphalt concrete, and asphalt sand. Sand can be obtained from natural mountain sand, river sand, etc. Artificial sand is of higher quality and less restricted by natural conditions, and is therefore increasingly widely used.
[0003] For sand and gravel with particle size requirements, they must be filtered through a wire mesh. The wire mesh is a wearing part. During operation, it is easy to break due to the wear and impact of the sand and gravel. After the wire breaks, a large leak is generated, which requires technical repair. In the existing technology, iron wire is generally used to reconnect. However, the wire mesh cannot be used for a long time after being reconnected with iron wire. Summary of the Invention
[0004] In view of the shortcomings of the existing technology, the utility model aims to provide a quick repair device for a sand and gravel filter screen to ensure the rapid repair of the steel wire mesh for filtering sand and gravel.
[0005] The technical solution adopted by the utility model is a quick repair device for a sand and gravel filter screen, comprising a pair of steel plates for connecting the damaged parts of the filter screen, wherein the length of the steel plates at both ends exceeds the broken length of the steel wire in the filter screen by 3-5 cm; the width of the steel plates at both ends exceeds the broken width of the steel wire by 3-5 cm;
[0006] Stamped through holes are respectively provided on both end surfaces of the steel plates, and the outer edge portions of the through holes are concave. Countersunk bolt assemblies for connecting the steel plates are respectively provided in the through holes of the pair of steel plates, and the heads of the countersunk bolts are adapted to the concave surfaces of the outer edge portions of the through holes.
[0007] Furthermore, in the pair of steel plates, steel nails for fixing the steel plates are provided on the lower surface edge of the steel plate above the filter screen. The steel nails are inserted into the mesh holes of the filter screen and are interference fit in the mesh holes.
[0008] Furthermore, leakage holes with a size and density comparable to those of the steel wire mesh holes are evenly arranged on the main body between the through holes at both ends of the steel plate.
[0009] By adopting the above technical solution, when a sand and gravel filter screen has a broken individual steel wire during use, the device can be used to quickly repair it, ensuring that the sand and gravel filter screen can continue to work. The device is easy to use, fast and specific, simple to manufacture, and low in cost. BRIEF DESCRIPTION OF THE DRAWINGS

[0016] The present invention will be further described below with reference to the accompanying drawings. Example 1
[0017] refer to Figure 1 、 Figure 2 A quick repair device for a sand and gravel filter includes a pair of steel plates 1 for connecting the damaged parts of the filter. Of course, the two steel plates 1 are of equal size, and the length of the steel plates 1 at both ends exceeds the broken length of the steel wire in the filter by 3-5 cm; the width of the steel plates at both ends exceeds the broken width of the steel wire by 3-5 cm, so that the two steel plates 1 can be fixed on the filter body around the damaged parts of the adjacent filters.
[0018] Stamped through holes 2 are respectively provided on both end faces of the steel plate 1, and the outer edge portion of the through hole 2 is concave. Countersunk bolt 3 assemblies for connecting the steel plates are respectively provided in the through holes of the pair of steel plates, and the head of the countersunk bolt 3 is adapted to the concave surface of the outer edge portion of the through hole, that is, the head of the countersunk bolt 3 is just located in the concave surface of the outer edge portion of the through hole 2; of course, the countersunk bolt 3 is equipped with a nut 4 to fix the two steel plates 1. Example 2
[0019] refer to Figure 1 — Figure 3The basic structure of Example 2 is the same as that of Example 1; the improvement is that a steel nail 6 for fixing the steel plate is provided on the lower surface edge of the steel plate above the filter screen in a pair of steel plates 1, and the steel nail 6 is inserted into the mesh of the filter screen. Of course, the steel nail 6 is the mesh around the edge of the damaged part of the filter screen and is interference fit in the mesh. In this way, it is convenient to quickly fix the steel plate 1 first and then quickly assemble the countersunk bolt assembly. Example 3
[0020] refer to Figure 1 — Figure 5 The basic structure of Example 3 is the same as that of Example 1 or Example 2; the improvement lies in that, for the relatively large steel plate 1 used to repair the broken holes of the steel wire in the filter screen, in order to prevent the repairing surface from affecting the sand leakage, leakage holes 5 of the same size as the steel wire mesh holes are evenly arranged on the main body between the through holes at both ends of the steel plate 1, and the density of the leakage holes arranged on the main body of the steel plate 1 is equivalent to the density of the steel wire mesh holes.
