Description

Technical Field

[0001] This utility model relates to the technical field of down-the-hole impactor test benches, specifically a simple test bench for assembling down-the-hole impactors. Background Technology

[0002] Down-the-hole hammers are a component of down-the-hole drills and are considered working devices of the drill. They are widely used in drilling operations in metallurgy, coal mining, chemical industry, building materials mining, as well as in water conservancy, hydropower, highway, railway, national defense, and construction projects. They are suitable for dry drilling, mixed ventilation and water drilling, and wet drilling operations with water inflow into the blast hole. They are reliable in performance and are currently the ideal equipment for drilling blast holes. Down-the-hole hammers require assembly before use.

[0003] Existing down-the-hole hammers lack effective testing and treatment after assembly, which leads to potential problems if the assembled down-the-hole hammers are used directly. To address this, we provide a simple testing workbench for assembling down-the-hole hammers. Utility Model Content

[0004] The purpose of this utility model is to provide a simple test workbench for assembling down-the-hole impactors, so as to solve the problem mentioned in the background art that existing down-the-hole impactors lack effective testing and processing after assembly, which leads to the potential danger of directly using the assembled down-the-hole impactors.

[0005] To achieve the above objectives, the present invention provides the following technical solution: a simple test workbench for assembling a downhole impactor, comprising a workbench, a test frame and two vertical support plates welded to the upper end of the workbench, a crossbeam platform welded between the two vertical support plates, a hydraulic cylinder on the top of the crossbeam platform, and an electric push rod welded to the front end face of the test frame.

[0006] Also includes:

[0007] The lifting platform is positioned between the test frame and the crossbeam platform, and a drive motor is installed at the upper end of the lifting platform. A linkage frame plate is installed outside the drive motor, and the linkage frame plate and the lifting platform are an integral structure.

[0008] A support plate is set inside the test frame, and a connecting rod is welded to the upper end of the support plate. A linkage top block is welded to the upper end of the connecting rod, and the linkage top block is welded to the piston rod of the electric push rod.

[0009] A drive shaft is welded onto the output shaft of the drive motor, and a second receiving plate is provided at the lower end of the drive shaft. The second receiving plate and the drive shaft are an integral structure, and a magnet is embedded inside the second receiving plate.

[0010] The first receiving plate is fixedly mounted on the lower end of the second receiving plate by screws, and the lower end of the second receiving plate is provided with a connector, which is an integral part of the second receiving plate.

[0011] Preferably, guide grooves are provided on the inner walls of both vertical frame plates, and connecting sliders are movably arranged inside the two guide grooves. Both connecting sliders are integral with the lifting platform plate.

[0012] Preferably, both connecting sliders are provided with rollers inside, and the connecting sliders are connected to the guide groove through the rollers in rolling contact.

[0013] Preferably, a central through hole is provided at the center of the lifting platform, and a bearing seat is welded inside the central through hole. The output shaft of the drive motor is movably connected to the lifting platform through the bearing seat.

[0014] Preferably, the connector has a threaded groove inside, which is connected to the location of the magnet block.

[0015] Preferably, one end of the hydraulic cylinder piston rod is welded to the top of the linkage frame plate.

[0016] Compared with the prior art, the beneficial effects of this utility model are:

[0017] 1. This utility model involves stacking soil at the actual drilling location on a support plate, then driving a down-the-hole impactor to rotate via a drive motor, and simultaneously adjusting the lifting platform via a hydraulic cylinder and the support plate via an electric push rod. This allows the down-the-hole impactor to simulate drilling into the stacked soil during rotation, observing its stability and identifying potential hazards. Once the test is passed, the qualified down-the-hole impactor can be used for actual drilling operations. This overcomes the problem of existing down-the-hole impactors lacking effective testing after assembly, leading to potential hazards when used directly.

[0018] 2. By installing the assembled down-the-hole impactor onto the connector, the threaded joint of the down-the-hole impactor is connected to the threaded groove inside the connector. After the connection is completed, the first and second plates are fixedly connected by bolts, so that the threaded down-the-hole impactor is attracted and connected by the magnet, which further improves the stability of the down-the-hole impactor after assembly and testing.

[0024] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments.

[0025] Please see Figure 1-4 An embodiment of this utility model is provided: a simple test workbench for assembling a downhole impactor, including a workbench 1, a test frame 3 and two vertical support plates 2 welded to the upper end of the workbench 1, a crossbeam platform 6 welded between the two vertical support plates 2, a hydraulic cylinder 7 provided on the top of the crossbeam platform 6, and an electric push rod 4 welded to the front end face of the test frame 3.

[0026] Also includes:

[0027] The lifting platform 8 is positioned between the test frame 3 and the crossbeam platform 6, and a drive motor 10 is installed at the upper end of the lifting platform 8. A linkage frame plate 9 is installed outside the drive motor 10, and the linkage frame plate 9 and the lifting platform 8 are an integral structure.

[0028] The support plate 18 is set inside the test frame 3, and a connecting rod 17 is welded to the upper end of the support plate 18. A linkage top block 5 is welded to the upper end of the connecting rod 17, and the linkage top block 5 is welded to the piston rod of the electric push rod 4.

[0029] The drive shaft 21 is welded onto the output shaft of the drive motor 10, and a second receiving plate 20 is provided at the lower end of the drive shaft 21. The second receiving plate 20 and the drive shaft 21 are an integral structure, and a magnet block 23 is embedded inside the second receiving plate 20.

[0030] The first receiving plate 19 is fixedly mounted on the lower end of the second receiving plate 20 by screws, and the lower end of the second receiving plate 20 is provided with a connector 11, which is an integral structure with the second receiving plate 20.

[0031] In use, soil from the actual drilling location is piled on the support plate. Then, the drive motor rotates the down-the-hole impactor, and the hydraulic cylinder raises and lowers the lifting platform. Simultaneously, the electric push rod raises and lowers the support plate, allowing the down-the-hole impactor to simulate a down-the-hole drilling test on the piled-up soil during rotation. The stability of the down-the-hole impactor is observed during the test, thus eliminating potential problems. After passing the test, the qualified down-the-hole impactor is used for actual down-the-hole drilling work.

[0032] Please see Figure 2 Guide grooves 12 are provided on the inner walls of the two vertical frame plates 2. Connecting sliders 13 are movably installed inside the two guide grooves 12. The two connecting sliders 13 are integrated with the lifting platform plate 8. The guide grooves 12 provided on the inner walls of the two vertical frame plates 2 serve to assist the lifting platform plate 8 in guiding its movement.

[0033] Please see Figure 2 Both connecting sliders 13 are equipped with rollers 14 inside. The connecting sliders 13 are connected to the guide grooves 12 through the rollers 14. The rollers 14 inside both connecting sliders 13 play a role in assisting the guiding movement of the connecting sliders 13.

[0034] Please see Figure 1 and Figure 2 A central through hole 15 is provided at the center of the lifting platform plate 8. A bearing seat 16 is welded inside the central through hole 15. The output shaft of the drive motor 10 is movably connected to the lifting platform plate 8 through the bearing seat 16. The central through hole 15 provided at the center of the lifting platform plate 8 facilitates the extension of the output shaft of the drive motor 10.

[0035] Please see Figure 4 The connector 11 has a threaded groove 22 inside, which is connected to the location of the magnet block 23. The threaded groove 22 inside the connector 11 facilitates the corresponding connection of the threaded joint of the downhole impactor.

[0036] Please see Figure 1 One end of the piston rod of the hydraulic cylinder 7 is welded to the top of the linkage frame plate 9.

[0037] Working principle: During use, the assembled down-the-hole (DH) impactor is installed onto the connector 11, so that the threaded joint of the DH impactor corresponds to the threaded connection groove 22 inside the connector 11. After the connection is completed, the first plate 19 and the second plate 20 are fixedly connected by bolts, so that the threaded DH impactor is attracted and connected by the magnet 23, which further improves the stability of the DH impactor after assembly and testing. Soil from the actual drilling location is piled on the support plate 18. Then, the drive motor 10 drives the DH impactor to rotate, and the hydraulic cylinder 7 drives the lifting platform 8 to adjust its height. At the same time, the electric push rod 4 drives the support plate 18 to adjust its height. Thus, the DH impactor simulates a down-the-hole drilling test on the piled-up soil during the rotation process. The stability of the DH impactor is observed during the test, thereby eliminating potential hidden dangers during the test. After the test is passed, the qualified DH impactor is used for actual down-the-hole drilling work, completing the use of the simple test workbench for DH impactor assembly.
