Description

Technical Field

[0001] The utility model belongs to the technical field of safe protection of the bottom of a mine bin, and in particular relates to a safety protection platform for the bottom of a mine bin. Background Art

[0002] When inspecting the bottom of the ore bin, the ore bin needs to be emptied and personnel need to enter the ore bin to work. To ensure the safety of the inspection, the floating ore on the bin wall needs to be cleaned. This operation belongs to limited space operation and there are certain safety risks and hidden dangers. The traditional cleaning method is that every time 2m of ore is placed, personnel need to enter the ore bin to carry out cleaning work. In this process, the work intensity is high and the time is long. If a fixed protective device is set up, it is not convenient to dismantle and adjust it after the ore is placed and the cleaning work is completed, which affects the progress of the work. At the same time, there is a problem of excessive labor required. Utility Model Content

One end of the steel beam 32 is rotatably connected to the base 31.

[0015] A plurality of sleeves 13 are provided at the bottom of the support platform 1 , and a pointed inserting tube 4 is movably inserted in the sleeve 13 ; legs 12 are provided at the bottom around the support platform 1 ; and a spiral lifting rod 14 is connected to the bottom of the legs 12 .

[0016] The method of using the utility model comprises the following steps:

[0017] Step 1: Install the base 31 on the outer wall of the ore bin through anchor rods to fix the base 31 on the wall, rotate the support platform 1 as a whole to the ore bin opening through the rotation of the steel beam 32, and then slide the support platform 1 into the ore bin;

[0018] Step 2: Support the support platform 1 by using the legs 12, and adjust the support platform 1 to be stable and firm by adjusting the spiral lifting rods 14;

[0019] Step 3: Use the pointed cannula 4 to pass through the multiple casings 13 respectively, and drive the pointed cannula 4 into the ore pile to further stabilize the support platform 1. The operating personnel perform operations in the space below the support platform 1.

[0020] Embodiment 1,

[0021] The supporting platform 1 is an integrated component consisting of a platform frame 11, a support leg 12, a sleeve 13 and a spiral lifting rod 14. The slide rail mechanism 2 is composed of a slide rail 21 and a slideway 22. The rotating mechanism 3 is composed of a base 31 and a steel beam 32.

[0022] Before assembling the utility model, first cut the required various components according to the design size, and then assemble them to form the support platform 1, the slide rail mechanism 2 and the rotating mechanism 3. Among them, the platform frame 11 of the support platform 1 is made of 1mm thick color steel plate and 50mm channel steel. The main surface of the platform frame 11 is made of color steel plate, and the channel steel is used as the platform frame. The number of frames of the platform frame 11 is 4, and the number of through holes set on the outer channel steel is 5; the legs 12 and the sleeve 13 are made of steel pipes with a diameter of 50mm. The number of legs 12 set under the platform frame 11 is 4, and the height can be adjusted according to the size of the support leg 12 and the sleeve 13. According to actual needs, the legs 12 arranged under the platform frame 11 can be connected by folding but are not limited to this connection method. The spiral lifting rod 14 is connected to the legs 12 through threads using M30 nuts. The size of the spiral lifting rod 14 matches the inner diameter of the legs 12, and the number of spiral lifting rods 14 is consistent with the number of legs 12; the sleeve 13 is made of a steel pipe of a certain length, and the steel pipe has a circular hole. The sleeve 13 is connected to the lower channel steel of the platform frame 11 by bolts. The number of sleeves 13 arranged under the platform frame 11 is 5, which is consistent with the number of through holes set on the outer channel steel of the platform frame 11.

[0023] The slide rail 21 of the slide rail mechanism 2 is made of 80mm channel steel, and the slideway 22 is made of 100mm channel steel in a concave shape. The concave slideway 22 can effectively limit the slide rail 21. The outer diameter of the slide rail 21 matches the inner diameter of the slideway 22. The slide rail 21 is set at the bottom of the platform frame 11, and the slideway 22 is set on the steel beam 32 of the rotating mechanism 3. Both are connected by welding. The number of slide rails 21 and slideways 22 is the same, both 2.

[0024] The base 31 of the rotating mechanism 3 is made of two round steels with a diameter of 100 mm and a common steel plate with a thickness of 20 mm, and the base 31 is welded into a concave shape. The steel beam 32 is made of 100 mm square steel. One end of the steel beam 32 is rotatably connected to the concave part of the base 31, that is, between the two round steels.

[0025] During installation, you need to follow the steps below to carry out related work:

[0026] Step 1: Install the base 31 and steel beam 32 of the rotating mechanism 3, prefabricate 4 anchor rods at the installation point on the outer wall of the ore bin, pass the base 31 through the anchor rods, weld and fix it to the wall with the anchor rods, and then rotate the steel beam 32 to connect it between the two round steels of the base 31;

[0027] Step 2: Install the slideway 22 of the slide rail mechanism 2. The slideway 22 is set on the steel beam 32 of the rotating mechanism 3 and connected by welding. The distance between the two slideways 22 is not less than 800mm.

[0028] Step 3: Install the support platform 1 , first assemble the components of the support platform 1 , then weld the slide rail 21 to the bottom of the platform frame 11 , with the spacing being the same as that of the slideway 22 , and finally embed the slide rail 21 into the slideway 22 .

[0029] After the above steps, the installation is completed. When using, follow the steps below to carry out related operations:

[0030] Step 1: Rotate the support platform 1 as a whole to the ore bin opening through the rotating mechanism 3, and then slide the support platform 1 into the ore bin through the slide rail mechanism 2;

[0031] Step 2: Adjust the height of the legs 12 by adjusting the spiral lifting rods 14 to make the platform frame 11 support stable and firm;

[0032] Step 3: Use pointed cannulas 4 with a diameter of 30 mm to pass through the casing 13 respectively to support the overall support platform 1, and use a sledgehammer to drive the pointed cannulas 4 into the ore pile to strengthen the overall support strength of the support platform 1. The operators work in the space below the platform frame 11;

[0033] Step 4: After the cleaning operation is completed, the pointed cannula 4 is pulled out and the legs 12 are retracted, the support platform 1 is slid to its original position through the slide rail mechanism 2, and is rotated outside the ore bin through the steel beam 32 without affecting the normal ore discharge.
