Description

Technical Field

[0001] The utility model relates to the technical field of ore position measurement of ore passes, and particularly relates to a deep ore pass ore position measurement device applied to underground mines. Background Art

[0002] At present, there are mainly two methods for measuring the ore position of deep ore passes. Method 1: Estimation by throwing stones and listening to the sound. According to the time from throwing a stone to the sound transmitted when the stone reaches the bottom, the length of the distance from the ore pass wellhead to the remaining ore position in the ore pass is estimated. Generally, it is estimated according to the algorithm of ten meters per second. Since everyone has a deviation in feeling when calculating the time, the measurement result is inaccurate.

[0003] Method 2: Tie a measuring hammer to a measuring rope, lower the measuring rope into the ore pass. Under the gravity of the measuring hammer, the measuring rope and the hammer free fall downward until they reach the remaining ore position in the ore pass and then stop. The measuring personnel pull the measuring rope upward to tighten it. When feeling the weight of the measuring hammer, check how many meters of the measuring rope have been released to judge the ore position of the remaining ore quantity in the ore pass. However, the staff releasing the rope cannot directly observe whether the hammer really lands on the ore of the remaining ore position in the ore pass, or when the measuring rope is pulled upward, the measuring rope has not been tightened, resulting in inaccurate measurement. Content of the Utility Model

[0004] In view of this, the purpose of the utility model is to provide a deep ore pass ore position measurement device applied to underground mines to solve the problem that in the prior art, the staff cannot judge whether the hammer really lands on the ore of the remaining ore position in the ore pass, resulting in inaccurate measurement.

[0005] The utility model is realized through the following technical solutions:

[0006] A deep ore pass ore position measurement device applied to underground mines includes a measuring rope. One end of the measuring rope is fixedly connected with a first hammer body. A second hammer body is connected to the first hammer body, and a traction component is installed between the second hammer body and the first hammer body.

[0007] Further, the traction component includes an elastic rope, and two ends of the elastic rope are respectively fixedly connected with the side walls of the first hammer body and the second hammer body.

[0008] Further, both the first hammer body and the second hammer body are hemispherical, and the plane of the first hammer body faces the plane of the second hammer body.

[0009] Further, a frame is installed at one end of the measuring rope away from the first hammer body. A roller is rotatably connected to the frame. One end of the measuring rope away from the first hammer body is fixedly connected with the side wall of the roller. A driving mechanism is installed on the frame, and the driving mechanism is used to drive the roller to rotate.

[0010] Further, the driving mechanism includes a driving motor, and an output shaft of the driving motor is fixedly connected to a side wall of one end of the drum.

[0011] Further, partition plates are fixedly connected to both ends of the drum, and the measuring rope is located between the two partition plates.

[0012] Further, sleeves are fixedly connected to four corners of the bottom surface of the frame. Slide rods are slidably connected in the four sleeves, and locking components are installed between the four slide rods and the corresponding sleeves. When the locking components are in the unlocked state, the slide rods can slide along their length directions in the corresponding sleeves.

[0013] Further, a notch is cut along the length direction of the sleeve at one end close to the slide rod, and an external thread is machined on the outer side wall; the locking component includes a nut sleeved on the slide rod, and the nut is threadedly connected to the sleeve.

[0014] Further, scale lines are drawn on the measuring rope.

[0015] The beneficial effects of the present utility model are as follows:

[0016] For the deep shaft ore level measuring device applied to underground mines, the staff grabs one end of the measuring rope far away from the first hammer, and freely drops the first hammer and the second hammer from the shaft opening of the shaft into the shaft. Under the action of their own gravity, the first hammer and the second hammer drive the measuring rope to move downward. Since the second hammer is located below the first hammer, the second hammer will first reach the remaining ore level in the shaft and make a sound. After the second hammer reaches the remaining ore level in the shaft, the first hammer hits the second hammer under the action of the traction component and makes a sound again. After the staff hears the two impact sounds, they pull the measuring rope up a certain distance, and after feeling the weight of the first hammer, they can confirm that the first hammer reaches the remaining ore level in the shaft. Mark the position where the measuring rope is flush with the shaft opening. After pulling out the measuring rope, measure the length between the first hammer and the marked position of the measuring rope with the help of an external measuring tool (such as a tape measure) to obtain the position of the remaining ore level in the shaft. Compared with the prior art, the staff can more accurately judge whether the first hammer lands on the ore at the remaining ore level in the shaft, making the measurement result more accurate.

[0029] Working principle and usage method: Step 1: The staff grabs the end of the measuring rope 1 far from the first hammer 2, and freely drops the first hammer 2 and the second hammer 3 into the shaft from the shaft opening. The first hammer 2 and the second hammer 3 drive the measuring rope 1 to move downward under their own gravity.

[0030] Step 2: Since the second hammer 3 is located below the first hammer 2, the second hammer 3 will first reach the remaining ore level in the shaft and make a sound. After the second hammer 3 reaches the remaining ore level in the shaft, the first hammer 2 hits the second hammer 3 under the action of the traction assembly and makes a sound again.

[0031] Step 3: After the staff hears the two impact sounds, pull the measuring rope 1 up a certain distance. After feeling the weight of the first hammer 2, it can be confirmed that the first hammer 2 reaches the remaining ore level in the shaft.

[0032] Step 4: Mark the position where the measuring rope 1 is flush with the shaft opening. After pulling out the measuring rope 1, measure the length between the first hammer 2 and the marked position of the measuring rope 1 with the help of an external measuring tool (such as a tape measure) to obtain the position of the remaining ore level in the shaft.
