Description

Technical Field

[0001] The utility model relates to the technical field of rock drilling trolley testing, in particular to a drill rod axis-aligning auxiliary device for rock drilling trolley testing. Background Art

[0002] At present, when drilling rigs are tested at the factory, a rock load simulation test bench is usually used to simulate in real time the rotation and axial loads borne by the drill rod during the drilling process of the drilling rig, so as to evaluate the performance of the drill rod under different loads. However, in actual testing, the axis of the drill rod needs to be adjusted to a state where it basically coincides with the axis of the load cylinder. However, on-site testers usually use naked eye observation and then instruct the drilling rig driver to operate the boom to perform the docking operation between the drill rod and the rock load simulation test bench. However, due to the large degree of freedom of the boom and the relatively low accuracy of naked eye observation, the axis of the drill rod and the axis of the load cylinder are often misaligned. A certain angle is formed between the two arms, which applies lateral impact force to the test bench when the drill rod is subjected to impact test, thereby causing a large vibration of the entire rock load simulation test bench, which is prone to loosening of fasteners and severe wear of hydraulic pipelines. Long-term use will also seriously affect the service life of the rock load simulation test bench. In addition, various sensors and feedback controllers can be installed on the boom to achieve high-precision docking operation between the drill rod and the rock load simulation test bench by calculating the real-time posture information of the boom. However, this method is costly, difficult to operate, and requires modification of various types of drilling rigs, and has poor feasibility. Utility Model Content

[0005] As a further improvement of the above technical solution:

[0006] Furthermore, the mounting seat includes a mounting plate, a magnetic attraction portion arranged on the mounting plate and magnetically connected to the drilling assembly, and a sliding groove opened on the mounting plate and slidably matched with the moving part.

[0008] Furthermore, the drilling assembly includes a propulsion beam connected to the boom of the rock drilling trolley, a rock drill arranged on the propulsion beam, and a drill rod connected to the output end of the rock drill and arranged coaxially with the axis of the loading assembly. The end of the propulsion beam facing the rock drilling trolley is magnetically connected to the magnetic attraction part.

[0009] Further, the shape of the mounting plate is conformed to the shape of the end of the propulsion beam facing the drilling rig.

[0010] Furthermore, the guide assembly includes a plurality of drill supporting plates arranged at intervals on the rock load simulation test bench for guiding the drill rod, the drill supporting plates are provided with drill supporting holes coaxially arranged with the axis of the loading assembly, and the drill supporting plates and the drill supporting holes are arranged in one-to-one correspondence.

[0011] Furthermore, the loading assembly includes an axial load applying member for applying an axial load, a rotary load applying member abutting the output end of the axial load applying member for applying a rotary load to the drill rod, and a load buffer member arranged on the rotary load applying member for buffering the axial load applying member, and the axis of the axial load applying member and the axis of the rotary load applying member are coaxially arranged.

[0012] Furthermore, the axial load applying member is one of an oil cylinder, an air cylinder or an electric push rod.

[0013] Furthermore, the mounting seat includes a mounting plate, a connecting piece which penetrates the mounting plate and is threadedly connected to the drilling assembly and is used to assemble the mounting plate on the drilling assembly, and a sliding groove which is opened on the mounting plate and slidably cooperates with the moving piece.

[0014] Furthermore, a guide rail which is slidably matched with the loading assembly is arranged on the rock load simulation test bench.

[0015] The utility model has the following beneficial effects:

[0016] The utility model discloses a drilling rod axis auxiliary device for testing a rock drilling trolley. On a rock load simulation test bench where a loading assembly and a guide assembly are assembled in a test site, the axis auxiliary assembly is detachably connected to the drilling assembly through a mounting seat. A moving part is mounted through the mounting seat. The moving part moves relative to the mounting seat to be coaxially arranged with the drilling assembly. A traction rope and a positioning hammer are then mounted through the moving part. A reference line parallel to the axis of the loading assembly is set in the test site. Before the impact test begins, the driver drives the rock drilling trolley to make the front end of the drilling assembly pass through the guide hole of the guide assembly. Then, the driver ensures that the relative position of the front end of the drilling assembly remains unchanged. By observing the vertical position of the positioning hammer, the driver adjusts the vertical position of the tail end of the drilling assembly. Under the condition that the traction rope is ensured to be vertical, the lower end of the positioning hammer is brought into contact with the test site. Then, the driver observes the vertical position of the positioning hammer. Observe the horizontal position of the positioning hammer to adjust the horizontal position of the tail end of the drilling assembly so that the lower end of the positioning hammer contacts the reference line. Since the reference line and the axis of the loading assembly are parallel, the movable part and the drilling assembly are coaxially arranged, and since the length of the traction rope is equal to the vertical height of the axis of the loading assembly, the axes of the drilling assembly and the loading assembly can be coaxially arranged while ensuring that the traction rope is vertical and the positioning hammer is in contact with the reference line, thereby achieving high-precision docking. At this time, after removing the axis auxiliary assembly, subsequent testing work is carried out through the coordinated cooperation of the loading assembly and the drilling assembly. Compared with the prior art, while achieving high-precision docking of the drilling assembly and the loading assembly, the present scheme has a simple structure of the axis auxiliary assembly, is easy to operate, does not require improvement to the rock drilling rig, has good feasibility, is highly practical, and is suitable for wide promotion and application.
