[0014] The present invention provides a device for measuring the collapse and fracture zone of a mine goaf area. It has the following beneficial effects:

[0015] (1) This invention drives the roller by pushing the control box to move. The length of the crack zone can be measured by the distance the roller moves. At the same time, the motor rotates to drive the measuring rope to be paid out. The actual depth of the crack zone can be measured by measuring the length of the paid-out rope. The pad moves downward to support the equipment to prevent the center of gravity from shifting when the electric telescopic rod is extended, causing the equipment to tip over into the crack zone and affecting the measurement of the equipment. The arc plate moves downward to contact the roller and restrict the roller to prevent personnel from moving the equipment when measuring the depth, causing the equipment to shift. This may cause the measuring rope to get stuck between the crack zones and affect the measurement results of the measuring rope.

[0016] (2) The invention can prevent the measuring rope from being unevenly wound when it is wound up through the circular reciprocating motion. If the measuring rope is not evenly wound around the winding wheel, it may cause the measuring rope to become tangled or deformed when in use, and it will take time to untie the wound part, affecting work efficiency. By pushing the measuring rope by the push rod, it can prevent the measuring rope from getting stuck, causing the measuring rope to be unable to be effectively lowered, affecting the accuracy of the measurement result. By using the elastic force of the telescopic spring plate itself, the measuring rope is pushed together to prevent the measuring rope from being too loose when it is wound up, which may cause the measuring rope to be unable to be effectively wound up, affecting the winding effect.

[0017] (3) This invention uses the reciprocating motion of a brush to evenly lubricate the surface of the reciprocating screw, thereby preventing the reciprocating screw from rusting or being stuck by dust during long-term use during outdoor measurements, which would affect the winding of the equipment. At the same time, the connecting pipe to the inside of the oil storage tank will separate the sealing plate from the sealing ring, allowing the lubricating oil in the oil storage tank to be applied to the reciprocating screw through the connecting pipe and the brush. At the same time, it can prevent excessive lubrication from causing waste of resources. Quantitative lubrication can save resources and increase the service life. BRIEF DESCRIPTION OF THE DRAWINGS

The reciprocating motion of the brush 174 evenly lubricates the surface of the reciprocating screw rod 164 to prevent the reciprocating screw rod 164 from being lubricated for a long time during outdoor measurement. The connecting tube 173 will rust or be stuck by dust during use, which will affect the winding of the equipment. At the same time, the connecting tube 173 will contact the support rod 162 during movement, and the reverse force of the support rod 162 will push the connecting tube 173 to move into the oil storage tank 172. The movement of the connecting tube 173 into the oil storage tank 172 will drive the sealing slide 175 to move toward the oil inlet, and the oil inlet is sealed by the sealing slide 175. At the same time, the connecting tube 173 into the oil storage tank 172 will cause the sealing plate 178 to separate from the sealing ring 176, so that the lubricating oil in the oil storage tank 172 can be applied to the reciprocating screw 164 through the connecting tube 173 and the brush 174, and at the same time, it can prevent the waste of resources caused by excessive lubrication. Quantitative lubrication can save resources and increase the service life.
