Description

Technical Field

[0001] The utility model relates to the technical field of coal mine machinery manufacturing, in particular to a tool for quickly measuring the hole distance of a rack rail of a scraper conveyor. Background Art

[0002] In the accompanying scraper conveyor, the rack rail installed in the central trough is one of the main components for the conveyor's coal mining operations. The dimensional accuracy of the machined holes must be high, which is one of the factors that directly affects the proper functioning of the coal mining machine. After actual machining, the operator generally uses a vernier caliper to measure the rack rail hole spacing. This is done by measuring the diameters of the two holes, then measuring the inner diameter of the holes, and calculating the true center distance of the rack rail hole spacing. After machining, the rack rail is usually subject to random inspection and testing. Currently, the main method used is vernier calipers, which are inefficient. When the hole spacing exceeds 1000mm, a large vernier caliper must be carried, which is inefficient and time-consuming. Summary of the Invention

[0026] The following will be combined with the accompanying drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the embodiments described are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0027] In the description of the present invention, it should be understood that the terms "upper", "middle", "outer", "inner", "lower" and the like indicating directions or positional relationships are only for the convenience of describing the present invention and simplifying the description, and do not indicate or imply that the components or elements referred to must have a specific direction, be constructed and operated in a specific direction, and therefore should not be understood as limiting the present invention.

[0028] Please see Figures 1 to 8The present invention provides a tool for quickly measuring the hole spacing of a scraper conveyor rack rail, comprising a sliding ruler 02, a fixed ruler 03, a locking rod 07, and a positioning column 01. Two bosses 10 are symmetrically provided on either side of one end of the fixed ruler 03. The two bosses 10 and the front face of the fixed ruler 03 form a groove 20. A first connecting hole 08 is opened and closed at the other end of the fixed ruler 03. The sliding ruler 02 slides in the groove 20 along the length of the fixed ruler 03. A second connecting hole 09 is provided at the end of the sliding ruler 02 away from the first connecting hole 08. A scale value is provided on the front face of the sliding ruler 02. A first pressure plate 04 and a second pressure plate 05 are provided above the sliding ruler 02, correspondingly mounted on the two bosses 10, to prevent the sliding ruler 02 from separating from the fixed ruler 03. A locking rod 07 is mounted on the boss 10. The end of the locking rod 07 can extend into the groove 20 and abut against the side of the sliding ruler 02 to prevent the sliding ruler 02 from sliding relative to the fixed ruler 03. The positioning column 01 is installed in the first connecting hole 08 and the second connecting hole 09 respectively.

[0029] During use, the sliding ruler 02 is slid outward along the length of the fixed ruler 03 to extend the sliding ruler 02 outward. The positioning posts 01 are then inserted into the two corresponding holes of the rack. The sliding ruler 02 and the fixed ruler 03 are adjusted to be stable. The sliding ruler 02 and the fixed ruler 03 are then fixed with the locking rod 07 to prevent relative sliding. At this time, the scale indicated on the scale at the end of the boss 10 away from the first connecting hole 08 is the measured value of the hole spacing. The integer and decimal parts of the reading are added together to obtain the actual measured value of the rack hole spacing center distance. Throughout the use process, it is convenient to use, saves detection time, and has a simple measurement process. It can meet the measurement requirements of 13 types of racks, including rack hole spacing (589 to 1000) mm and hole diameter (52 to 78) mm.

[0030] In one embodiment, a spring 06 is disposed on the inner wall of the groove 20. This spring 06 contacts the end of a locking rod 07, allowing the end of the locking rod 07 to press the spring 06 against the side of the sliding ruler 02. When the end of the locking rod 07 presses the spring 06 against the side of the sliding ruler 02, the sliding ruler 02 and the fixed ruler 03 cannot slide relative to each other. To move the sliding ruler 02, simply loosen the locking rod 07, releasing the spring 06 from its tight fit with the side of the sliding ruler 02. This allows the sliding ruler 02 and the fixed ruler 03 to slide relative to each other, thereby adjusting the distance between the two positioning posts 01.

[0031] Specifically, a stopper 61 is provided at each end of the spring 06, giving the spring 06 an overall "concave" shape. The inner wall of the stopper 61 abuts against the outer wall of the two ends of the boss 10. The stopper 61 can confine the spring 06 within the groove 20, preventing the spring 06 from moving in the longitudinal direction of the fixed ruler 03.

[0032] Specifically, the reed 06 is positioned and attached to the side of the sliding ruler 02 by a screw installed on the side of the boss 10 opposite to the reed 06. It should be noted that when the screw is used to position the reed 06, the reed 06 only needs to be in contact with the side of the sliding ruler 02.

[0033] In one embodiment, there are two locking rods 07 , and the two locking rods 07 are respectively installed on the two bosses 10 in a threaded connection manner.

[0034] In one embodiment, the first pressing plate 04 and the second pressing plate 05 are correspondingly mounted on the two bosses 10 by screws to facilitate installation and removal.

[0035] In one embodiment, positioning pins 01 are threadedly mounted in first and second connection holes 08 and 09, respectively. When measuring hole pitch, different positioning pins 01 can be replaced based on the rack hole diameter. The rack hole pitch measurement range is 580-1000 mm, making it suitable for measuring the hole pitch of various rack types.

[0036] The above disclosure is only a preferred embodiment of the present invention, and it is certainly not intended to limit the scope of the rights of the present invention. A person skilled in the art can understand that all or part of the processes of the above embodiment and equivalent changes made in accordance with the claims of the present invention are still within the scope of the present invention.
