Description

Technical Field

[0001] This utility model relates to the technical field of rock drill testing equipment, specifically a rock drill testing platform capable of sensing distance by pulling a rope. Background Technology

[0002] The rock drilling rig test equipment is a platform specifically designed to simulate actual working environments and test the performance of rock drilling rigs. The rock drilling rig test equipment includes a steel structure support, an installation platform, a guide frame, quick connectors, a gearbox, brake calipers, a brake disc, linear guides, bearing seats, a torque sensor, a dynamometer, a hydraulic cylinder, a rope sensor, a fence, and a control system.

[0003] A rock drill impact and operation test platform, belonging to the field of engineering machinery technology, is disclosed in publication number CN218511992U. This rock drill impact and operation test platform includes a base with shock-absorbing components. The base includes a rock drill base, a running base, and a rock drill base. The rock drill base is equipped with a shock absorber. The rock drill base is connected to the running base, with one end of the running base connected to the rock drill base and the other end connected to the rock drill base. This invention enhances the overall seismic resistance of the test platform by incorporating shock-absorbing components in the base, reducing both vibration and noise. Furthermore, the shock absorber in the rock drill base enhances its shock absorption effect, reducing vibration during testing, preventing frequent bolt breakage, and also reducing noise.

[0004] When conducting dynamometer tests on rock drills, the dynamometer equipment and the rock drill itself need to be moved on the test bench. During the test, the advancing speed of the rock drill needs to be measured. However, existing test benches use rulers or sensors to measure the advancing distance of the rock drill. This method is not very intuitive, and the distance data can only be measured when the sensor is in its designated position. This requires strict control over the installation position and number of sensors. It is necessary to determine the exact location of the sensors and how many to install to make direct measurements of the moving test equipment. As a result, the entire measurement process is not very intuitive, and the measurement accuracy for a constantly moving rock drill is poor.

[0005] Therefore, those skilled in the art have provided a rock drill test bench capable of sensing distance by pulling a rope to solve the problems mentioned in the background art. Utility Model Content

[0006] The purpose of this invention is to provide a rock drill test bench capable of sensing distance with a pull rope, in order to solve the problem mentioned in the background art that existing rock drill test benches are not conducive to measuring the distance of rock drill test equipment in motion during the testing process.

[0007] To achieve the above objectives, this utility model provides the following technical solution:

[0008] A test bench for a rock drill capable of sensing distance via a pull rope includes: a test bench, a grid plate fixedly mounted on the upper surface of the test bench by screws, a grating mounted on the surface of the grid plate, an installation platform slidably mounted above the test bench, a positioning seat fixedly mounted on the left side of the test bench, an anti-collision rubber seat fixedly mounted on the surface of the positioning seat, a support seat one fixedly mounted on the left side of the anti-collision rubber seat, a support seat two mounted on the left side of the support seat one, a wire roller rotatably connected to the inner side of the support seat two, a coil spring plate mounted on one side of the wire roller, a guide wire groove fixedly mounted on the inner side of the support seat one, a guide wire hole seat through the interior of the anti-collision rubber seat, and a pull rope wound around the surface of the wire roller.

[0009] As a further improvement of this utility model: the pull rope on the roller passes through the inside of the guide wire hole seat through the guide wire groove, and the moving end of the pull rope is fixedly connected to a marking seat.

[0010] As a further improvement of this utility model: a hanging ring is connected to the surface of the marking base, and a hook is fixedly connected to the left side surface of the mounting platform.

[0011] As a further embodiment of this utility model: the marking base is connected to the hook on the left side of the mounting platform by a hanging ring, and the mounting platform is connected to the roller by a pull rope.

[0012] As a further embodiment of this utility model: the grid plate is fixedly connected to the test bench, and several grid plates are evenly distributed along the test bench, with the spacing between the gratings on the surface of the grid plate remaining consistent.

[0013] As a further embodiment of this utility model: the roller is connected to one end of the spring plate assembly inside the spring plate, and the roller and the second support base are rotating.

[0014] Compared with the prior art, the beneficial effects of this utility model are:

[0015] An installation platform is slidably mounted on the test bench. A pull rope is connected to the back of the installation platform, and the other end of the pull rope is wound onto a roller. The roller and the spring disc form a rotatable connection. When the installation platform moves forward along the test bench, it pulls the pull rope forward. A marker is installed at the end of the pull rope connected to the installation platform. The roller and the spring disc interact with each other. Utilizing the elastic potential energy of the spring inside the spring disc, the rotation of the roller has a certain resistance. Combined with the movement of the installation platform, the pull rope is tightened. Every time the installation platform moves forward by one grid plate, the grating on the grid plate will be sensed. The spacing between the gratings is the same, so each time a set of gratings is passed, it can be marked and sensed, which is conducive to calculating the moving distance. Furthermore, pulling the pull rope makes it more intuitive. At the same time, the sensing of the gratings is conducive to real-time distance sensing of the installation platform in a continuously moving state. After the test ends, the elastic potential energy stored in the spring inside the spring disc is released, pulling the installation platform back to the starting test end.

[0021] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0022] Please see Figures 1-4This utility model provides a test bench for a rock drill capable of sensing distance using a pull-rope system. The test bench 1 has a grid plate 2 fixedly mounted on its upper surface by screws. A grating 16 is mounted on the surface of the grid plate 2. The grating 16 is an existing device, and using a grating for distance measurement is also prior art, as illustrated in Chinese Patent Publication No. CN221077569U. The principle of grating 16 distance measurement is a mature technology, and will not be discussed in detail here. However, grating distance measurement alone is not the complete improvement of the technical solution of this application, but only one aspect of the technical solution. Part of it is a direct reference to mature technology. An installation platform 3 is slidably installed above the test bench 1. A positioning seat 4 is fixedly installed on the left side of the test bench 1. An anti-collision rubber seat 9 is fixedly installed on the surface of the positioning seat 4. A support seat 11 is fixedly installed on the left side of the anti-collision rubber seat 9. A support seat 2 12 is installed on the left side of the support seat 11. A wire roller 13 is rotatably connected to the inner side of the support seat 2 12. A coil spring plate 14 is installed on one side of the wire roller 13. One end of the coil spring plate assembly inside the coil spring plate 14 is connected to the wire roller 13. The wire roller 13 and the support seat 2 12 are rotating.

[0023] Specifically, the pull rope 8 wound on the wire roller 13 passes through the guide wire groove 15 and enters the guide wire hole seat 10, and then passes through the guide wire hole seat 10 and the anti-collision rubber seat 9. After passing through, it connects to the marker seat 6. The marker seat 6 is connected to the mounting platform 3 through the hook 5 and the hanging ring 7. During the movement of the mounting platform 3, the pull rope 8 will be pulled. After the pull rope 8 is pulled, the wire roller 13 at the other end of the pull rope 8 will rotate. During the rotation, the coil spring inside the coil spring plate 14 will be pulled, thereby causing the coil spring to store elastic potential energy. The elastic potential energy is used to increase the rotational resistance of the wire roller 13 and the rebound reset. In this way, the pull rope 8 can be tightened. At the same time, after the test is completed, the elastic potential energy of the coil spring is released, and the mounting platform 3 will automatically pull back to the starting position of the test, improving the convenience of the test process.

[0024] A guide groove 15 is fixedly installed on the inner side of the support base 11, a guide hole seat 10 is installed through the inside of the anti-collision rubber seat 9, and a pull rope 8 is wound on the surface of the roller 13.

[0025] The pull rope 8 on the wire roller 13 passes through the guide wire groove 15 and is inserted into the inside of the guide wire hole seat 10. The moving end of the pull rope 8 is fixedly connected to the mark seat 6. The surface of the mark seat 6 is connected to the hanging ring 7. The left side surface of the mounting platform 3 is fixedly connected to the hook 5. The mark seat 6 is hooked to the hook 5 on the left side of the mounting platform 3 through the hanging ring 7. The mounting platform 3 is connected to the wire roller 13 through the pull rope 8. The grid plate 2 is fixedly connected to the test bench 1. Several grid plates 2 are evenly distributed along the test bench 1. The spacing between the gratings 16 on the surface of the grid plate 2 is consistent.

[0026] Specifically, one end of the pull rope 8 is connected to the marker seat 6. The marker seat 6 is connected to the hook 5 on the mounting platform 3 via the hanging ring 7, thereby connecting the pull rope 8 to one side of the mounting platform 3. When the mounting platform 3 slides forward along the test bench 1, it pulls the pull rope 8. During the movement of the mounting platform 3, whenever the platform moves forward a distance of one grid plate 2, the grating 16 on the grid plate 2 will sense this movement. Since the spacing between the gratings 16 is equidistant, whenever the mounting platform 3 passes a set of gratings 16, these gratings 16 will be sensed in sequence, thus providing an accurate mark for calculating the movement distance. This enhances the intuitiveness of the movement distance. Moreover, through the sensing function of the gratings 16, the position of the mounting platform 3 in the continuous movement state can be accurately measured in real time. This real-time distance sensing mechanism, combined with the use of the pull rope 8, makes the measurement of the mounting platform 3 by the test equipment more efficient and accurate.

[0027] The working principle of this utility model is as follows:

[0028] When using this utility model, firstly, the rock drill is fixed on the mounting platform 3. The mounting platform 3 moves above the test bench 1. During the movement, the mounting platform 3 pulls the pull rope 8, which is connected to the marker seat 6 through the guide groove 15 and the guide hole seat 10. The marker seat 6 is connected to the hook 5 on the mounting platform 3 through the hanging ring 7, thereby connecting the pull rope 8 to one side of the mounting platform 3. As the mounting platform 3 moves, each time it passes the grating 16 on the grid plate 2, the grating 16 will sense this movement. When the mounting platform 3 passes a set of gratings 16, these gratings... All 16 will be sensed sequentially, providing a precise marker for calculating the moving distance, thus calculating the distance the installation platform 3 has moved. At the same time, due to the connection between the wire roller 13 and the spring plate assembly inside the spring plate 14, the spring plate will store elastic potential energy during the pulling process of the pull rope 8. When the test is over, the elastic potential energy of the spring plate is released, driving the wire roller 13 to rotate, thereby retracting the pull rope 8, so that the installation platform 3 automatically returns to the starting position of the test, preparing for the next test. The whole process realizes the accurate measurement of the moving distance of the rock drill, improving the convenience and efficiency of the test.

[0029] The above description is only a preferred embodiment of the present utility model, but the protection scope of the present utility model is not limited thereto. Any equivalent substitutions or changes made by those skilled in the art within the technical scope disclosed in the present utility model, based on the technical solution and the inventive concept of the present utility model, should be included within the protection scope of the present utility model.
