However, research on special facilities for deep pit operations in the power industry is still at a relatively backward level, and standardized equipment has not been used, resulting in frequent safety accidents and many suffocation and casualties. The cause of the accidents is largely due to the fact that a large number of construction workers rely on themselves to warn and take measures, but this protection mechanism is not safe and reliable, because when construction workers discover danger, it may be too late. Therefore, how to rely on equipment to actively and timely discover dangers and warn, and automatically take effective measures, and provide more safety functions to strengthen protection and reduce casualties, is an urgent and key research issue.

[0042] The maximum lifting height is 24m;

[0043] The rated lifting weight of the material is 50Kg;

[0044] The rated lifting weight for personnel is 75kg;

[0045] Gas detection objects: oxygen, carbon monoxide, hydrogen sulfide, combustible gas;

[0046] Gas content display mode: LED digital display;

[0047] Gas exceeding the limit and personnel safety alarm mode: sound and light alarm;

[0048] Alarm volume: ≥90 decibels;

[0049] Air supply volume: 4m 3 / min; air supply pressure is 885Pa; the maximum air supply depth can reach 25m.

[0050] The installation and use process of the present invention is:

[0051] First, assemble the foundation pit support 1 beside the pit mouth. The specific assembly steps are as follows:

[0052] The first step is to take out the four pillars 102 and the top bracket 101, first insert the top bracket connecting rod 109 of the top bracket 101 into the four pillars 102, and reliably connect them with a φ16 pin shaft;

[0053] The second step is to install the hanging points of the fall arrester and the ladder, take out the six beams (four middle beams 103, two bottom beams 105) and two support beams 108, and hang each hanging point on the middle beam 103 with the protective cover 115 according to the markings on the beams and support beams 108;

[0054] The third step is to install the crossbeams. The support beam connecting sleeve 114 on the support beam 108 is put on the two middle crossbeams 103 and reliably connected with a pin. The support beam 108 and the middle crossbeam 103 are marked with serial numbers. The same serial numbers can be used for assembly;

[0055] Finally, the legs 106 are inserted into the pillars 102 .

[0056] Then, move the foundation pit support 1 to the top of the foundation pit, adjust the size of the foundation pit support 1 to match the pile diameter, and anchor the four legs 106 with a steel chisel; fix the track 3 on the top support 101, and install the material lifting and shifting electric hoist 2 on the track 3; hang the control instrument box 4 on the foundation pit support 1; after the fan 5 and the air duct are connected and fixed, install the entire exhaust device on the fan installation plate; slowly hoist the exhaust duct and the detector into the foundation pit (it should be noted that in order to ensure the normal operation of the fan 5, the distance between the fan 5 outlet and the bottom of the foundation pit should be kept between 1 and 1.5 meters); connect the power cords of the main power supply, electric hoist, gas detector and fan 5 to the corresponding sockets according to the markings on the control instrument box 4 panel, and the control instrument box 4 and the foundation pit support 1 are reliably grounded with a grounding wire. Install the emergency lifting electric hoist 6 above the foundation pit support 1.

[0057] Start the generator, close the main power supply, electric hoist, protection, and air switches of the fan 5 on the control panel (the voltage used in the electrical system of the present invention is 220 volts, and anti-electric shock measures must be taken when using it. The gas detector will self-check after being powered on. After the self-check is completed, the carbon monoxide content, combustible gas content, hydrogen sulfide content, and oxygen content in the current environment will be displayed); press the "START" start button on the remote control of the material lifting and shifting electric hoist 2, run it at no load, check the lifting, shifting, and braking conditions, ensure that it works normally, and the limit switch is safe and effective, and start normal operation. The gas detector detects the carbon monoxide, combustible gas, hydrogen sulfide, and oxygen content in the foundation pit. When the content of the four gases does not meet the set value, the alarm device automatically alarms; install safety enclosures, and finally check that each hanging point 107, emergency rescue pulley, etc. are reliably installed; the operator urgently lifts the electric hoist 6 to ensure smooth operation. Construction work can begin after all parts have been tested and run well.

[0058] The material lifting and shifting electric hoist 2 is connected by ropes to realize the lifting and lowering of the material barrel 7 placed in the deep foundation pit. After the material barrel 7 reaches the pit mouth, it moves out of the foundation pit support 1 through the track 3. After the latch 704 on the barrel body 701 is pulled out, the barrel mouth will automatically turn downward, and the material can be automatically unloaded. After unloading, the material barrel 7 is shifted to the top of the pit mouth through the track 3, and then driven down to the bottom of the pit to load the material, and the reciprocating lifting realizes the loading and unloading of the material.
