AI Technical Summary
The maintenance or replacement of existing mining saw blades is time-consuming and labor-intensive, requiring the disassembly of large protective covers, which is cumbersome and inconvenient.
The system employs a protective alarm unit, which includes a first fixed post, a second fixed post, a protective wire, and a sensor. The sensor detects vibration of the protective wire and triggers an alarm, simplifying the saw blade maintenance or replacement process.
The saw blade can be quickly maintained or replaced without removing the protective cover, improving maintenance efficiency. It also features a safety warning function, accurate sensor detection, and better safety.

TECHNICAL FIELD
[0001] The utility model relates to mine mechanical equipment technical field, especially a kind of new mine sawing machine. BACKGROUND
[0002] Mine sawing machine is a kind of heavy machinery equipment for cutting, mining or crushing in mine, and mine saw is used to cut ore into small pieces suitable for extraction or processing, and can also be used for mining in quarry or rock mining field, which can effectively cut, crush or separate rock. The existing mine saw usually uses motor as driving source, and the power generated is transmitted to the saw blade through the transmission shaft to drive it to rotate quickly. When the saw blade rotates, it cuts, crushes or separates ore, rock and other materials through the teeth on the saw blade. The mine sawing machine is usually equipped with a control system, and the operator can start and stop the sawing machine, adjust the speed of the saw blade and the cutting parameters through the control panel or computer interface to meet different working requirements. In actual use, the saw blade is fixedly installed on the sawing machine, and a protective cover connected with the machine body is arranged on the outer side of the saw blade. When the saw blade needs to be replaced or maintained, the protective cover needs to be removed first. Since the mine sawing machine is a large equipment, the entire protective cover is too large to be removed and installed with the help of a hoisting vehicle, which makes the maintenance or replacement of the saw blade time-consuming and labor-intensive. SUMMARY
[0003] Therefore, in view of the above problems, the utility model provides a new mine sawing machine with simple and reasonable structure, convenient and fast saw blade maintenance or replacement.
[0004] To solve this technical problem, the utility model adopts the following scheme: a new mine sawing machine, including machine body and saw blade and control system arranged on the machine body, further comprising at least one set of protective alarm unit, each set of protective alarm unit comprises first fixed column, second fixed column, protective line, sensor and alarm, the first fixed column and the second fixed column are respectively arranged on the same side of the machine body where the saw blade is installed, and the first fixed column and the second fixed column are located on the left and right parts of the machine body, the protective line is arranged on the first fixed column and the second fixed column at both ends, and at least one end of the protective line is detachably connected with the first fixed column or the second fixed column, the middle part of the protective line spans the outer side of the saw blade, the sensor is arranged on one end of the protective line to detect whether the protective line shakes in real time and sends the detection information to the control system of the machine body, and the alarm is connected with the output end of the control system to alarm the shaking of the protective line.
[0005] Further improvement includes at least two sets of protective alarm units, each set of protective alarm unit is arranged in parallel on the machine body with an interval, and the middle part of the protective line of each set of protective alarm unit spans the outer side of the saw blade.
[0006] Further improvement, the protective line is any one of steel cable, iron cable, iron wire, steel wire, nylon rope, synthetic fiber rope.
[0007] Further improvement, the sensor is a pull rope displacement sensor.
[0008] By adopting the foregoing technical scheme, the saw blade can be maintained or replaced only by dismounting the detachable end of the protective line of each group of protective alarm units, the structure is simple and reasonable, the saw blade is convenient and fast to maintain or replace, after replacement or maintenance, the protective line can be installed again, the detachable protective line and the first fixing column or the second fixing column are convenient to dismount, the protective cover does not need to be hoisted and operated, the protective alarm unit can also play a safety warning protection role, the safety protection performance is better through the multiple groups of anti-skid alarm units arranged across the outer side of the saw blade, the sensor is a pull rope displacement sensor, the detection is more accurate, the safety protection effect is better, and the utility model can be widely applied. BRIEF DESCRIPTION OF DRAWINGS
[0009] Figure 1 is the front structure schematic diagram of the utility model embodiment. DETAILED DESCRIPTION
[0010] The utility model will be further explained in connection with the drawings and specific embodiments.
[0011] REFERENCE Figure 1 Preferably, the novel mine saw machine of the utility model, including body 1 and being located on body 1 saw blade 2, control system and two groups of protective alarm units, each group of protective alarm units all includes first fixed column 31, second fixed column 32, protective line 33, sensor 34 and alarm, the protective line 33 is steel cable, and the sensor 34 is pull rope displacement sensor, first fixed column 31 and second fixed column 32 are located on the same side of body 1 installation saw blade 2 respectively and first fixed column 31 and second fixed column 32 are located on the left part and right part of body 1, the both ends of protective line 33 are located on first fixed column 31 and second fixed column 32 respectively, one end of protective line 33 is detachably connected with first fixed column 31 and the other end of protective line 33 is fixedly connected with second fixed column 32, the middle part of protective line 33 is across the outer side of saw blade 2, sensor 34 is located on one end of protective line 33 and detects whether protective line 33 shakes in real time and sends detection information to the control system of body 1, and the alarm is connected with the output end of control system and alarms when detecting that protective line 33 shakes, and two groups of protective alarm units are arranged in parallel on body 1 with interval.
[0012] The number of groups of the protection alarm units in the above embodiments can be set according to the size of the machine body and different requirements, each group of the protection alarm units is arranged in parallel on the machine body in an up-down interval, and the protection line of each group of the protection alarm units is across the outside of the saw blade. The protection line can also be any one of a wire rope, a wire, a steel wire, a nylon rope, and a synthetic fiber rope. The sensor can also be a conventional displacement sensor or a vibration sensor for detection. The use of the pull rope displacement sensor is to detect the protection line more accurately.
