Installation and commissioning of automatic sports car protection device

1. Read the manual and the working schematic diagram carefully before use.

2. Before installation, check whether the equipment is in good condition and whether the models and specifications are consistent. Then install according to the schematic diagram of installation on site, and the specific installation size will be determined according to the actual situation on site.

2.1 Electrical installation: The control box for inclined shaft sports car protection device, the mine safety infrared sensor and the mine flameproof reversible vacuum electromagnetic starter can be installed on the roadway wall or placed in the opening hole of the roadway wall to avoid water immersion. At the same time, the transmitting and receiving parts of the mine intrinsically safe infrared sensor should be aligned. The mine intrinsically safe position sensor should be installed on the winch to confirm the state of the winch and whether the bar is opened or closed in place. The connection method of electrical products is shown in the circuit connection diagram of sports car protection device

2.2 Refer to the general drawing of sports car protection device for mechanical installation

(1) buffer foundation 1500(length)X1000 (width)X1000 (depth) is filled with cement and gravel and the anchor bolts are buried according to the size.

(2) When the buffer is assembled, the wire rope shall be compressed. According to the weight of tandem cars, about 6 ~ 10m is reserved for the tail rope. Buffer structure principle see buffer general diagram

(3) The width of the car bar shall be determined according to the needs of the site and shall be limited to the maximum width of the car material. The wire rope is embedded into the shaped tube steel to fix the blocking state.

(4) Suspension link should be divided evenly between the three wire ropes, the top one should be about 15cm from the top edge of the vehicle and the bottom one should be about 10cm above the frame.

(5) with a 6 x37 + FC - Φ 8 mm cable is a head of wear to the actuator of the wheel in a groove on the card, and wire rope on the rope wheel clockwise or counterclockwise tightly coiled in 3 to 5 times and pull rope head, will be fixed in the channel steel rope head through the side of the pulley, and hook clamp to rack up by credit card on the bottom of a pipe steel. Another 6 x37 + FC - Φ 8 mm steel wire on one end and a 6 x37 + FC - Φ 8 mm wire rope take appropriate location, with wire rope card merger in mind, on the other side through the fixed in another channel steel side of the pulley, and the corresponding hook clamp to rack up by credit card on the bottom of a pipe steel. Put a 6 x37 + FC - Φ 26 mm wire rope can be folded in half through the finalize the design after the pipe steel, in turn formed three wire rope, junction with rope card pin down, and the wire connector smooth processing.

(6) When the hoisting rope of the car bar is running up and down, it should be flexible and smooth without any obstructing phenomenon.

(7) The block group is a key block part in the protective blocking device of sports car. The quality of steel wire rope, installation quality, installation distance and tail rope length are the key factors. Therefore, it should be treated with caution, strengthen inspection, inspection and maintenance at normal times, and timely deal with problems found.

3. After the installation of the inclined shaft sports car protection device, it shall be debuggable and run, and tested item by item according to its working principle and functions of each mating device. The installation and operation of each mating device shall be checked one by one. After the acceptance of the device, the operator shall be trained in operation, which shall include basic operation requirements, matters needing attention in use and troubleshooting methods.

Precautions for fully automatic sports car protection device

1. The connection of all devices in the inclined shaft sports car protection device should be correct, and the device configuration should not be changed;

2. The specification, model and parameters of components and components of the intrinsically safe circuit and circuits related to intrinsically safe circuit shall not be changed during equipment maintenance;

3. Live maintenance is strictly prohibited;

4. Those who are not familiar with the device are strictly prohibited to operate the device.

Maintenance and maintenance of automatic sports car protective device

1. Pay attention to the daily maintenance of the device and carry out regular overhaul;

2. The surface of the intrinsically safe infrared sensor used for mining should be kept clean to ensure the effective monitoring of the car.

3. Regular inspection should be conducted on the mechanical moving components such as wire rope, winch for retracting and releasing, and bar for blocking, to ensure that the device should be sensitive in starting, flexible in rotation, and in place for recovery, and no loosening of the fixed parts.
