Abstract
The utility model discloses a U-shaped bolt for a scraper. The U-shaped bolt for the scraper comprises a strip-shaped block, convex circular cones, screw rods and nuts; the strip-shaped block has a strip shape with a rectangular section; two symmetrically arranged grooves are formed in the bottom surface of the strip-shaped block and are arc; the two circular cones are arranged at the lower bottom surface of the strip-shaped block and are symmetrically arranged relative to the strip-shaped block; the screw rods are integrally arranged on the convex circular cones; the nuts are connected with threads at the lower half sections of the screw rods in a match mode; protruded edges are arranged at the upper ends of the nuts of which the lower ends are arc guide surfaces. The U-shaped bolt for the scraper has the beneficial effects that materials are saved during production, taking and placing can be conveniently performed, the screw rods can be more firmly connected by the convex circular cones and can not be damaged after long-term use. The contact surface during the connection is increased by the protruded edges, the guide surfaces achieve a guide action for the spanner, the connection is firmer and the service life is longer.
Description
Technical field
The utility model relates to the technical field, particularly a kind of scraper plate U-bolt being fixedly connected with bolt.
Background technique
People in daily life, be unable to do without with coal, coal can be used for generating, steam locomotive, building materials, boiler oil and metallurgy thermal coal, or coking coal, in life, use the place of coal ubiquitous, present people utilize carbon scraper to gather coal, therefore utilizing scraper plate scrapes the coal in the earth's crust to take out, present scraper plate connection all utilizes bolt to connect, during work, scraper plate is connected on chain, chain-driving scraper plate scraping coal, yet due to the firm scraping difficulty of coal, be easy to make the bolt connecting rupture or damage and can not use midway, so not only can cause the damage of scraper plate, more serious meeting causes carbon scraper to use.
Model utility content
For addressing the above problem, the purpose of this utility model be to provide a kind of simple in structure, be connected firmly, the scraper plate U-bolt of long service life.
For achieving the above object, the technical solution of the utility model:
A kind of scraper plate U-bolt, comprise bar blocks, dome platform, screw rod, nut, described bar blocks is the strip that cross section is rectangle, and bar blocks upper bottom surface has two symmetrically arranged grooves, and groove is curved, on bar blocks bottom surface, be provided with two dome platforms, the relative bar blocks of two dome platforms is symmetrical arranged, and on dome platform, has been wholely set screw rod, on screw rod lower semisection screw thread, is connected with nut, nut upper end is provided with outstanding edge, and lower end is circular arc guide surface.
As preferably, described bar blocks, dome platform and screw rod utilize cast iron integral type die cast.
As preferably, in described bar blocks, seamed edge and corner position are done circular arc and are processed.
Beneficial conditions of the present utility model is: when producing, both saved material, and the installation of conveniently taking, it is more firm that dome platform can make screw rod connect, permanent use can not damage, outstanding edge has increased the area of contact while connecting, guide surface is that spanner plays leading role, connect more firm, long service life.
Accompanying drawing explanation
Fig. 1 is plan view of the present utility model.
Fig. 2 is plan view of the present utility model.
Embodiment
As shown in Figure 1, 2, a kind of scraper plate U-bolt, comprise bar blocks 1, dome platform 3, screw rod 4, nut 6, the strip that described bar blocks 1 is rectangle for cross section, bar blocks 1 upper bottom surface has two symmetrically arranged grooves 2, groove 2 is curved, on bar blocks 1 bottom surface, be provided with two dome platforms 3, the relative bar blocks 1 of two dome platforms 3 is symmetrical arranged, on dome platform 3, be wholely set screw rod 4, on screw rod 4 lower semisection screw threads 5, be connected with nut 6, nut 6 upper ends are provided with outstanding along 7, and lower end is circular arc guide surface 8.Described bar blocks 1, dome platform 3 utilize cast iron integral type die cast with screw rod 4.In described bar blocks 1, seamed edge and corner position are done circular arc processing.Bar blocks 1 upper bottom surface of the present utility model has two symmetrically arranged grooves 2, when producing, both saved material, and the installation of conveniently taking, bar blocks 1 bottom surface utilizes dome platform 3 to be provided with screw rod 4, it is more firm that dome platform 3 can make screw rod 4 connect, permanent use can not damage, nut 6 upper ends are provided with outstanding along 7, lower end is circular arc guide surface 8, during connection, give prominence to the area of contact while having increased connection along 7, guide surface 8 plays leading role for spanner, nutting 6 is convenient, and can not scratch hand, two screw rods 4 together connect, connect more firm, long service life.
