Abstract
The utility model provides a kind of tool ruler of surely spending hole range finding for feeder, and feeder is provided with two and surely spends hole, comprise blade and two one end can with the described bolt of surely spending hole and fixing, the other end of bolt is cylindrical abutting end; Blade is provided with slide rail, and slide rail is provided with slide block, and slide block is provided with the be slidably matched hole corresponding with the cylindrical abutting end of bolt, and blade one end is provided with a secure fit hole corresponding with the cylindrical abutting end of bolt.During measurement, first two bolts are spent on hole surely at two respectively and fix, then by the secure fit borehole jack of this tool ruler on a bolt, the be slidably matched hole of the other end on slide block can adjust position makes it coordinate with another bolt abutting end, the numerical value of scale corresponding on blade can be read, thus measure the centre distance that hole spent surely by feeder two accurately.
Description
Technical field
The utility model relates to a kind of belt weight coal conveyer weighing system, belongs to feeder technical field.
Background technology
Classical belt weight coal conveyer, given degree probe hole finishing on lathe of its belt conveyer scale is formed.In theory and design, we give tacit consent to two centre distance surely spending hole is constant definite values, and its numerical value equals theoretical value, and mismachining tolerance can be ignored.And in fact along with on market to constantly increasing of requiring of feeder weighing precision and level uneven in processing, the impact that mismachining tolerance weighing system precision causes has become a major influence factors.Therefore, the Accurate Measurement of degree of determining hole centre distance is just become to the important content ensureing weighing precision.Replaced the way of actual value can not continue to adopt by theoretical value in the past.For new requirement, we need have the value of a more high-precision requirement to set to its degree of determining hole centre distance before every platform feeder dispatches from the factory and participate in calculating into the computing system of weighing, ensure precision.
Utility model content
The technical problems to be solved in the utility model is to provide a kind of tool ruler of the given degree probe hole centre distance for measuring belt conveyer scale of coal feeder.
In order to solve the problems of the technologies described above, the technical solution of the utility model is to provide a kind of tool ruler of surely spending hole range finding for feeder, feeder is provided with two and surely spends hole, it is characterized in that: comprise blade and two one end can with the described bolt of surely spending hole and fixing, the other end of bolt is cylindrical abutting end; Blade is provided with slide rail, and slide rail is provided with slide block, and slide block is provided with the be slidably matched hole corresponding with the cylindrical abutting end of bolt, and blade one end is provided with a secure fit hole corresponding with the cylindrical abutting end of bolt.
Preferably, described slide block is provided with scale mark, and the blade outside slide rail is provided with the size scale of corresponding slide block.
During measurement, first two bolts are spent on hole surely at two respectively and fix, on the bolt of the secure fit borehole jack on the left side of the tool ruler one end then the utility model provided, the be slidably matched hole of the other end on slide block can adjust position makes the bolt position on itself and the right roughly the same, the hole that is slidably matched is inserted on the cylindrical fit end of bolt, such blade and slide block are just fixed by two bolts, its relative distance is also fixed, groove on final level range estimation slide block and the reading between the scale on blade can directly read numerical value accurately.
The device that the utility model provides overcomes the deficiencies in the prior art, can measure the centre distance that hole spent surely by feeder two accurately.
Accompanying drawing explanation
The tool ruler schematic diagram of surely spending hole range finding for feeder that Fig. 1 provides for the utility model;
What Fig. 2 provided for the utility model spends schematic diagram when the tool ruler of finding range in hole uses surely for feeder.
Embodiment
For making the utility model become apparent, hereby with a preferred embodiment, and accompanying drawing is coordinated to be described in detail below.
In order to measure the centre distance that two are spent hole surely, make two identical degree of determining hole bolts, one end of bolt can be fixed on degree of determining hole, and other one end of bolt is cylindrical abutting end, for coordinating with tool ruler.
Fig. 1 is tool ruler schematic diagram, described tool ruler of surely spending hole range finding for feeder comprises blade 2, blade 2 is provided with slide rail 3, slide rail 3 is provided with slide block 5, slide block 5 is provided with the be slidably matched hole corresponding with the cylindrical abutting end of bolt, with scale mark on slide block 5, the blade outside slide rail is provided with the size scale of corresponding slide block.Blade 2 one end is also provided with a secure fit hole corresponding with cylindrical abutting end.The cylindrical abutting end of bolt can insert this secure fit hole and tight cooperation, and equally, the cylindrical abutting end of bolt also can insert the hole that is slidably matched and carry out link cooperation.
What Fig. 2 provided for the utility model spends schematic diagram when the tool ruler of finding range in hole uses surely for feeder, during measurement, first two bolts 6 are spent on hole 8 surely at two respectively and fix, on the bolt of the secure fit borehole jack on the left side of tool ruler 7 one end then the utility model provided, the be slidably matched hole of the other end on slide block can adjust position makes the bolt position on itself and the right roughly the same, the hole that is slidably matched is inserted on the cylindrical fit end of bolt, such blade and slide block are just fixed by two bolts, its relative distance is also fixed, groove on final level range estimation slide block and the reading between the scale on blade can directly read numerical value accurately.
