[0034] To make the objectives, technical solutions, and advantages of the embodiments of this utility model clearer, the technical solutions in the embodiments of this utility model are described clearly and completely. Obviously, the described embodiments are only some embodiments of this utility model, not all embodiments. Based on the embodiments of this utility model, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of this utility model.

[0035] This application provides an installation structure for a drilling rig speed measuring device, which solves the problem that the contact wheel on existing drilling rig speed measuring devices tends to deviate from the contact surface after long-term use, thereby improving the speed measuring effect of the drilling rig speed measuring device.

[0036] The technical solution in this application is to solve the above-mentioned technical problems, and the general idea is as follows:

[0037] In the existing technology, a drilling rig is used in conjunction with a drilling rig speed measuring device to drill water curtain holes and record the drilling rate of the drill rod. However, after a long period of use, the contact wheel on the drilling rig speed measuring device is prone to deviating from the contact surface, so the speed measuring effect of the drilling rig speed measuring device is not good.

[0038] Research has found that, for example Figures 1-5 As shown, by setting up an installation structure, a hollow disc and a spring are installed on the installation structure. The elastic force generated by the spring relative to the outer surface of the hollow disc is used to control the drilling rig speed measuring device to always keep it in close contact with the machine body after installation. This ensures that the contact wheel on the drilling rig speed measuring device is in close contact with the contact surface on the machine body, making it easy for the contact wheel to slide in close contact with the contact surface, thus realizing the speed measurement of the drilling rig speed measuring device.

[0039] To better understand the above technical solutions, the following will provide a detailed explanation of the technical solutions in conjunction with the accompanying drawings and specific implementation methods.

[0040] Example:

[0041] like Figures 1-6 As shown, a mounting structure for a drilling rig speed measuring device is provided, wherein the drilling rig speed measuring device 35 is mounted on the body 1 via the mounting structure.

[0042] The installation structure includes a connecting block 3 and a mounting column 30. The drilling rig speed measuring device 35 includes a pulse converter and a contact wheel 36. The contact wheel 36 is rotatably connected to the pulse converter through a bearing and abuts against the contact surface 37 of the machine body 1.

[0043] The mounting column 30 and the drilling speed measuring device 35 are located at both ends of the connecting block 3 and fixed to the connecting block 3. The mounting column 30 is connected to the push block 20 that is slidably connected to the machine body 1 through the bracket 31.

[0044] The bracket 31 is fixedly connected to the push block 20 by bolts. The bracket 31 has a limit hole and a notch 311. The mounting post 30 is installed through the limit hole and fixed by fastening bolts through the fastening hole 312 and locking the notch 311.

[0045] A hollow disc 32 is installed on the mounting column 30, and a spring 4 is installed on the connecting block 3. The spring 4 surrounds the outer surface of the hollow disc 32, and the protruding end formed by the spring 4 under the action of the hollow disc 32 faces the machine body 1. The spring 4 is used to pull the contact wheel 36 on the drilling speed measuring device 35 to be tightly attached to the contact surface 37 on the machine body 1.

[0046] By setting up an installation structure, the drilling rig speed measuring device 35 can be installed. The entire installation process is convenient and efficient, and it is easy to disassemble and install the drilling rig speed measuring device 35. It is also convenient to replace and repair the pulse converter and contact wheel 36 on the drilling rig speed measuring device 35 in the future.

[0047] Meanwhile, when setting up the installation structure, a hollow disc 32 and a spring 4 are set on the installation structure. The elastic force generated by the spring 4 relative to the outer surface of the hollow disc 32 is used to control the drilling speed measuring device 35 to always keep it in close contact with the machine body 1 after installation. This allows the contact wheel 36 on the drilling speed measuring device 35 to be in close contact with the contact surface 37 on the machine body 1, making it easy for the contact wheel 36 to slide in close contact with the contact surface 37, thus realizing the speed measurement of the drilling speed measuring device 35.

[0048] Specifically, the hollow disc 32 is sleeved on the mounting post 30 and fixed to the mounting post 30 by multiple bolts passing through the corresponding threaded holes 321.

[0049] By setting the hollow disc 32 to be detachably connected to the mounting column 30, the installation of the hollow disc 32 can be facilitated, and the replacement of the hollow disc 32 can be facilitated. This allows for adjustment of the convex arc of the spring 4 surrounding the hollow disc 32, thereby adjusting the spring 4 to achieve the tightness between the contact wheel 36 and the contact surface 37, enhancing the stability of the contact wheel 36 when sliding along the contact surface 37, and ensuring the speed measurement accuracy of the drilling rig speed measuring device 35.

[0050] like Figures 1-2 as well as Figure 4 As shown, the connecting block 3 is equipped with a first limiting post 33 and a second limiting post 34. The two ends of the spring 4 are respectively sleeved on the first limiting post 33 and the second limiting post 34 and partially surround the outer surface of the hollow disc 32 to form a protrusion facing the body 1.

[0051] After being fitted, the two ends of the spring 4 are welded to the corresponding limiting post 1 33 and limiting post 2 34, respectively.

[0052] By setting limit post 1 33 and limit post 2 34, the spring 4 is initially fixed so that the spring 4 can be welded later, thereby improving the stability of the spring 4 during installation and use.

[0053] Specifically, both limit post 1 33 and limit post 2 34 are welded to the connecting block 3.

[0054] like Figure 1 as well as Figures 5-6 As shown, a drill rod propulsion assembly 2 is installed on the push block 20, and the drill rod on the drill rod propulsion assembly 2 slides with the machine body 1 through the push block 20;

[0055] The drill pipe propulsion assembly 2 is electrically connected to the pulse converter on the drilling rig speed measuring device 35 via a signal line 351.

[0056] The push block 20 is equipped with multiple wire clamps 381 on the side near the bracket 31. Each wire clamp 381 is fixed to the body 1 by a bolt passing through the corresponding threaded hole 38.

[0057] The signal line 351 is attached to the push block 20 via the corresponding wire clamp 381.

[0058] By setting multiple wire clamps 381 on the push block 20, the signal line 351 is bound by the wire clamps 381, which strengthens the stability of the electrical connection between the signal line 351 and the drill rod propulsion assembly 2 and the drill speed measuring device 35, and facilitates the speed measuring operation of the drill speed measuring device 35.

[0059] It should be noted that during application, wire clamps 381 can be installed on the connecting block 3 and the bracket 31 as needed, so that the signal line 351 can be fixed along the wiring direction of the drill rod propulsion assembly 2 and the drilling speed measuring device 35, and the drill rod and the drill rod propulsion device 2 can be detachably connected, so that the corresponding drill rod can be replaced as needed.

[0060] Specifically, the edge of the contact wheel 36 that contacts the contact surface 37 on the body 1 is patterned to increase the friction when the contact wheel 36 slides relative to the contact surface 37, thereby enhancing the stability of the contact wheel 36 during rotation.

[0061] During operation, the push block 20 moves forward or backward along the drilling direction of the machine body 1, driving the drill rod on the drill rod propulsion assembly 2 to move forward or backward, thereby realizing the drilling-related operations of the drilling machine.

[0062] When the push block 20 drives the drill rod forward or backward, the drilling speed measuring device 35, which is fixed to the push block 20 by the installation structure, moves forward with the push block 20 and moves backward with the push block 20.

[0063] When the drilling rig speed measuring device 35 moves forward or backward, the contact wheel 36 on the drilling rig speed measuring device 35 slides along the contact surface 37 on the machine body 1. Through the sliding of the contact wheel 36, the rotating wheel of the contact wheel 36 generates a pulse signal. Forward movement is pulse A and backward movement is pulse B. The pulse magnitude is related to the circumference of the contact wheel 36. After processing by a microcomputer, it is converted into the forward and backward speed, i.e., the drilling speed, and the pulse signal and related data are transmitted to the display terminal. The pulse converter speed measurement here is existing technology and will not be described in detail here.

[0064] When installing the drilling speed measuring device 35, the bracket 31 is first fixed to the push block 20 with bolts. Then, the connecting block 3, which is fixedly connected to the drilling speed measuring device 35 and the hollow disc 32, is inserted into the fastening hole 312 of the bracket 31 through the mounting column 30. The mounting column 30 is fixed by fastening bolts passing through the fastening hole 312 and locking notch 311, and the contact wheel 36 on the drilling speed measuring device 35 is in contact with the contact surface 37 of the machine body 1.

[0065] Before the connecting block 3 is installed on the bracket 31, the drilling speed measuring device 35 needs to be fixed to the connecting block 3, and the hollow disc 32 needs to be sleeved on the mounting column 30 and fixed to the mounting column 30 with multiple bolts. After the hollow disc 32 is installed, the spring 4 is passed through the hollow disc 32 on the side close to the machine body 1, and the two ends of the spring 4 are respectively sleeved on the corresponding limit post 1 33 and limit post 2 34, and the two ends of the spring 4 after being sleeved are welded to the connecting block 3, thus completing the preliminary preparation for the connecting block 3 to be installed on the bracket 31 through the mounting column 30.

[0066] The contact wheel 36 of the drilling speed measuring device 35 has good pressure resistance and wear resistance. At the same time, the bracket 31 of the drilling speed measuring device 35 uses the tension of the spring 4 to keep the wheel in close contact with the drilling platform. When the drilling rig drills or pulls out the drill rod, there will be no slippage, ensuring real-time recording of the drilling and rod retraction of the drilling rig.

[0067] In summary, compared with existing technologies, it has the following beneficial effects:

[0068] 1. By setting up an installation structure, the drilling rig speed measuring device 35 can be installed. The entire installation process is convenient and efficient, and it is easy to disassemble and install the drilling rig speed measuring device 35. It is also convenient to replace and repair the pulse converter and contact wheel 36 on the drilling rig speed measuring device 35 in the future.

[0069] Meanwhile, when setting up the installation structure, a hollow disc 32 and a spring 4 are set on the installation structure. The elastic force generated by the spring 4 relative to the outer surface of the hollow disc 32 is used to control the drilling speed measuring device 35 to always keep it in close contact with the machine body 1 after installation. This allows the contact wheel 36 on the drilling speed measuring device 35 to be in close contact with the contact surface 37 on the machine body 1, making it easy for the contact wheel 36 to slide in close contact with the contact surface 37, thus realizing the speed measurement of the drilling speed measuring device 35.

[0070] 2. By setting limit post 1 33 and limit post 2 34, the spring 4 is initially fixed so that the spring 4 can be welded later, thereby improving the stability of the spring 4 during installation and use.

[0071] 3. By setting multiple wire clamps 381 on the push block 20, the signal line 351 is bound by the wire clamps 381, which strengthens the stability of the electrical connection between the signal line 351 and the drill rod propulsion assembly 2 and the drill speed measuring device 35, and facilitates the speed measuring operation of the drill speed measuring device 35.
