Detailed Description

As shown in fig. 1 to 3, an automatic conveyor belt replacing machine for a steel slag magnetic separation production line comprises a base 1, wherein a pair of symmetrically distributed supports 2 is respectively arranged at two sides of the base 1, a driving shaft 3 is arranged between one pair of supports 2, a driven shaft 4 is arranged between the other pair of supports 2, the driving shaft 3 is used for winding an old belt 10, the driven shaft 4 is used for winding a new belt 9, and a first flat carrier roller 5 is further arranged on the base 1 between the two pairs of supports 2; one side of the driven shaft 4, which is far away from the driving shaft 3, is also provided with a pair of second flat carrier rollers 6 which are distributed up and down, and a tension wheel 7 is arranged above the second flat carrier rollers 6.

The drive shaft 3 is driven by a motor reducer 11. And two ends of the driving shaft 3 and two ends of the driven shaft 4 are fixed by bearing seats (including bearings). Vertical carrier rollers 8 are further arranged at two ends of the first flat carrier roller 5 in the length direction. The vertical carrier roller 8 is rotatably fixed by I-shaped steel (including a bearing). The second flat carrier roller 6 and the tension wheel 7 are arranged on the same vertical frame and are fixed by bearing blocks (including bearings).

The whole frame of the novel structure can be formed by welding H-shaped steel with the thickness of 400mm and 140mm, and can also be made into a split bolt connection type of an active part and a passive part, so that the movement is convenient; the design can meet the requirement of replacing the mining conveying belt with the thickness of below 800 mm; the driving shaft is made of a thick-walled seamless steel pipe with the diameter phi of 76mm by 8mm, and is fixed by a steel clamp, so that the driving shaft is convenient to disassemble and assemble; when the belt is replaced, the belt replacement is completed under the assistance of the tension wheel and two second flat carrier rollers additionally arranged at the belt replacement position, and the belt replacement is used as a belt guide function; when the belt is replaced, the equipment is hoisted to a replacement position, a new belt is placed on the driven shaft, and the joint is fixed with the old belt at the tensioning wheel; the old belt passes through the first flat supporting roller and is connected with the driving shaft, a starting button of the motor speed reducer is pressed, and the belt starts to be automatically replaced.

The method comprises the following specific steps:

1. and (4) overlapping the new adhesive tape head with the old adhesive tape, wherein the overlapped part must avoid the vulcanized joint of the old adhesive tape. The lap joint amount is controlled at 200mm, and 4M 10X 45 flat head bolts are used for connection and firm fixation, and the lap joint is chamfered.

2. Old belt with broken lap joint under 10m line

One end of an old belt under a 10-meter line is firstly lapped with the broken old belt, the lapping amount is controlled to be 200mm, the old belt and the broken old belt are connected by 4M 10 multiplied by 45 flat head bolts and are firmly fixed, and the lapping joint is chamfered; the other end is inserted and fixed on the hollow shaft of the driving shaft.

3. And after the internal inspection of the belt gallery is finished, starting a driving shaft motor of the automatic replacement belt conveyor, operating at the belt speed of less than or equal to 0.5m/s in forward rotation, starting to roll the old belt, and simultaneously driving the new belt to be on line. In the process, a special person is required to track and check the lap joint of the new and old adhesive tapes so as to prevent the lap joint from scraping the machine frame or cracking in the running process. When the lap joint is conveyed to the tensioning wheel, the head wheel and the tail wheel, a tracker needs to check at any time and timely inform ground personnel of the conveying condition.

4. And (3) after all the old belts are off-line and coiled, the new belts are on-line and connected to the tensioning wheel, the lap joints of the old belts are disconnected, the on-line new belt joints are lapped, a belt head wheel motor is started to convey the lap joints to the position of the vulcanization bonding belts in the belt gallery, and the vulcanization bonding belts are started.

The vulcanization bonding is completely standard process specifications, and comprises the procedures of belt cutting, rough stripping, polishing, glue paste brushing, bottom glue laying, arrangement, upper glue laying, vulcanizer assembling, pressurizing and heating, constant temperature and pressure, natural cooling and the like. The total length of the joint is 1200mm, the joint angle is 16.70, and a lap joint method is adopted. Firstly, stripping the upper and lower layers of covering glue of the adhesive tape by 20cm along a joint transition region; polishing by a straight polishing machine, and paying attention to the fact that a line layer cannot be polished; then brushing special adhesive cement on the polished surface, and paving bottom layer adhesive. The belts are lapped, and the vulcanizer is arranged by paying attention to the penetrating rod for arranging the vulcanization beam. In the key processes of pressing, cooling and the like, the joint is controlled to reach 150 +/-5 ℃ and the pressure is controlled to be 1.2-1.5 MPa. When the temperature reaches 150 ℃, the temperature is automatically preserved, the temperature is continuously maintained for 110min, and the pressure is kept constant. And after the constant temperature and the constant pressure are finished, the vulcanizer is removed after the joint temperature is naturally cooled to below 70 ℃.

And loosening the clips on the two sides of the old belt roll on the driving shaft of the automatic belt changer, hoisting the clips to a belt recovery area, drawing out the hollow shaft, and installing the hollow shaft on the main shaft of the automatic belt changer for next use.
