[0003] Among them, when using a hanging hammer, the measuring observer needs to look for the hanging hammer line and prism in the observation mirror. The measuring ruler personnel must illuminate the front and rear view points. After the observer finds the target, he measures once. If the error is within the allowable range, he will change the station for measurement.
[0004] When the hanging hammer on the market is in use, the hammer cone tip is easily damaged by colliding with the ground and cannot be used, while the other parts of the hanging hammer are intact. If the entire hanging hammer is discarded and replaced with a new one, it will inevitably cause a waste of resources. Therefore, a new technical solution needs to be designed to solve the problem. A detachable protective cover can be installed on the bottom of the hanging hammer to protect the hanging hammer. Utility Model Content

[0021] See also Figure 1-3 The utility model provides a technical solution: a mining engineering surveying hammer, comprising a hammer 1, a cover 12 being detachably mounted on the bottom of the hammer 1, four groups of equally spaced docking holes 13 being opened on the top outer side of the cover 12, and a quick-install positioning mechanism being mounted on the hammer 1;
[0022] The quick-install positioning mechanism includes a slide groove 2 opened at one end of the outer bottom of the hammer 1, a slider 21 slidably installed in the slide groove 2, a stop pin 22 fixedly installed on one side of the slider 21, a spring 26 fixedly installed on the other side of the slider 21, three groups of equidistantly distributed sockets 23 opened on the outer bottom of the hammer 1 and a pin 24 inserted into each group of sockets 23, the other side of the spring 26 is fixedly installed on the inner wall of the slide groove 2, the two adjacent groups of docking holes 13 and the slide groove 2 are movably connected with the stop pin 22, and the two adjacent groups of docking holes 13 and the sockets 23 are movably connected with the pin 24.
[0023] In this technical solution, when the operator installs the outer cover 12, he can squeeze the stop pin 22 in the quick-install positioning mechanism, push the slider 21 in the slide 2, and squeeze the spring 26, so that the stop pin 22 is completely received in the inner wall of the slide 2, and wait for a group of docking holes 13 of the outer cover 12 to dock with the slide 2, and then release the stop pin 22 in the slide 2. The stop pin 22 can be automatically squeezed into the docking hole 13 by the spring 26 to support the outer cover 12. The operator inserts the pin 24 into the other three groups of corresponding docking holes 13 and the plug hole 23. Without the need for multiple operators, the outer cover 12 with a larger mass can be quickly installed at the bottom of the hammer 1 to protect the bottom of the hammer 1.
[0024] In some technical solutions, a wire hole 32 is opened in the middle of the connecting cover 3, and a hanging rope 33 is movably installed in the wire hole 32. A stopper 34 is fixedly installed at the bottom of the hanging rope 33. The cross-sectional area of the stopper 34 is larger than the cross-sectional area inside the wire hole 32, which facilitates the positioning of the hanging rope 33 inside the connecting cover 3.
[0025] In this technical solution, when the operator limits the block 34 at one end of the lifting rope 33 to the inner wall of the connecting cover 3, and passes the lifting rope 33 through the wire hole 32 in the middle of the connecting cover 3, and waits for the connecting cover 3 to be threadedly connected with the connecting head 11, the hanging hammer 1 can be hoisted and measured. In addition, the wire hole 32 and the connecting head 11 are distributed in the center position of the hanging hammer 1, which can ensure that the center of gravity of the hanging hammer 1 and the lifting rope 33 are on the same vertical line, further improving the measurement accuracy of the hanging hammer 1.
[0026] In some technical solutions, a connecting head 11 is fixedly installed on the top of the hammer 1, and a connecting cover 3 is installed on the top of the connecting head 11, so that the hammer 1 can be suspended. A threaded groove 31 is provided on the bottom side of the connecting cover 3, and the threaded groove 31 is threadedly connected to the outer wall of the connecting head 11, which facilitates the installation and disassembly of the connecting cover 3.
[0027] In this technical solution, after the operator has threadedly connected the threaded groove 31 inside the connecting cover 3 to the connecting head 11 , the connecting cover 3 can be firmly fixed on the top of the hanging hammer 1 , making it easier for the hanging rope 33 to hang the hanging hammer 1 .

[0029] In this technical solution, when the pin 24 is inserted into the inner wall of the two adjacent groups of sockets 23 and the docking hole 13, the magnetic tube 25 installed inside the socket 23 can adsorb the pin 24 to prevent the pin 24 from falling out of the socket 23.
[0030] When using a mining engineering surveying hammer, it should be noted that the utility model is a mining engineering surveying hammer, and each component is a universal standard part or a component known to technical personnel in this field. Its structure and principle can be known to technical personnel through technical manuals or through conventional experimental methods.
[0031] When in use, the operator can first install the outer cover 12 at the bottom of the hammer 1 before using the hammer 1 to protect the bottom of the hammer 1 to prevent the cone tip of the hammer 1 from colliding with the ground and causing damage and becoming unusable. At the same time, when the operator is installing the outer cover 12, he can squeeze the stop pin 22 in the quick-install positioning mechanism, push the slider 21 in the slide 2, and squeeze the spring 26 so that the stop pin 22 is completely received in the inner wall of the slide 2. After waiting for one group of docking holes 13 of the outer cover 12 to dock with the slide 2, release the stop pin 22 in the slide 2, and the stop pin 22 can be automatically squeezed into the docking hole 13 by the spring 26 to support the outer cover 12. The operator can put the other three groups of corresponding docking holes 13 and sockets 23 into the inner wall of the slide 2. By plugging in the upper pin 24, the larger outer cover 12 can be quickly installed at the bottom of the hammer 1 without the need for multiple operators to protect the bottom of the hammer 1. At the same time, a wire hole 32 is opened in the middle of the connecting cover 3, and a lifting rope 33 is movably installed in the wire hole 32. When the operator limits the block 34 at one end of the lifting rope 33 to the inner wall of the connecting cover 3, and passes the lifting rope 33 into the wire hole 32 in the middle of the connecting cover 3, and waits for the connecting cover 3 to be threadedly connected with the connecting head 11, the hammer 1 can be hoisted and measured. In combination with the wire hole 32 and the connecting head 11 being distributed at the center of the hammer 1, it can be ensured that the center of gravity of the hammer 1 and the lifting rope 33 are in the same vertical line, thereby further improving the measurement accuracy of the hammer 1.
