Technical Field
[0001] This utility model belongs to the field of wrench technology and relates to wrenches for mechanical maintenance of mining equipment. Background Technology
[0002] Mining electrical equipment operates in harsh environments. When a fault occurs or the scheduled maintenance cycle is reached, the equipment enclosure must be opened for mechanical maintenance. Therefore, the locking mechanism that matches the equipment enclosure must be flexible and reliable. Most of the fastening of mining electrical equipment uses hexagonal wrenches with internal or external hexagonal structures, so hexagonal wrenches are widely used.
[0003] The drawbacks of existing hex wrenches are that they cannot easily replace hex heads of different specifications during use, and the torque cannot be adjusted during use, thus failing to achieve the effect of saving effort. To address this, we have designed a wrench for the mechanical maintenance of mining equipment. Summary of the Invention

[0006] In the aforementioned wrench for mechanical maintenance of mining equipment, a guide ring is provided between the insertion connecting sleeve and one end of the wrench cylinder, an oil storage cylinder section is installed inside the wrench cylinder section, and an oil outlet plate is provided at one end of the oil storage cylinder section, with the oil outlet plate corresponding to the guide ring.
[0007] In the aforementioned wrench for mechanical maintenance of mining equipment, a pressing head is installed at the other end of the oil storage cylinder section, and the pressing head is located at the other end of the wrench cylinder.
[0008] In the aforementioned wrench for mechanical maintenance of mining equipment, a through hole is provided at the top of the wrench cylinder, a torque arm is installed inside the through hole, a limit ball head is installed at one end of the torque arm, and an extension connecting rod is slidably installed at the other end of the torque arm.
[0009] In the aforementioned wrench for mechanical maintenance of mining equipment, the sliding distance of the extension link relative to the torque arm is two-thirds of the length of the torque arm.
[0010] In the aforementioned wrench used for mechanical maintenance of mining equipment, the surface of the wrench cylinder is provided with multiple weight-reducing holes.
[0011] Compared with existing technologies, the advantages of this utility model of a wrench for mechanical maintenance of mining equipment are as follows: By inserting the positioning connecting pin into the insertion connecting sleeve, the internal hexagonal wrench head is connected to the wrench cylinder. A bolt adjusting pin is installed on the side of the wrench cylinder, and a threaded connection hole is opened on the side of the positioning connecting pin. The other end of the bolt adjusting pin is connected to the threaded connection hole. The tightness of the bolt adjusting pin can be easily adjusted by adjusting the handle, thereby realizing the quick disassembly and installation and replacement of the internal hexagonal wrench head, which is very convenient. In addition, an extension connecting rod is slidably installed at the other end of the torque arm. The sliding distance of the extension connecting rod relative to the torque arm is two-thirds of the length of the torque arm, which makes it easy to increase the torque arm distance during use, thereby achieving the effect of saving effort, reducing the labor intensity during use, and ensuring the convenience of use.

[0016] The following are specific embodiments of the present invention, which are described in conjunction with the accompanying drawings. However, the present invention is not limited to these embodiments.
[0017] like Figure 1 , Figure 2 and Figure 3 As shown, this utility model relates to a wrench for mechanical maintenance of mining equipment;
[0018] Example 1: The wrench includes a wrench cylinder 1 and an internal hex head 2. One end of the wrench cylinder 1 is fitted with an insertion connecting sleeve 7, and one end of the internal hex head 2 is fitted with a positioning connecting post 8. The positioning connecting post 8 is inserted into the insertion connecting sleeve 7 so that the internal hex head 2 is connected to the wrench cylinder 1. A bolt adjusting post 11 is installed on the side of the wrench cylinder 1. One end of the bolt adjusting post 11 is fitted with an adjusting handle 10. A threaded connection hole 9 is opened on the side of the positioning connecting post 8, and the other end of the bolt adjusting post 11 is connected to the threaded connection hole 9.
[0019] In this embodiment, in order to achieve a lubrication effect on the internal hex wrench head 2, a guide ring 12 is provided between the insertion connecting sleeve 7 and one end of the wrench cylinder 1. An oil reservoir section 13 is installed inside the wrench cylinder 1.
