Abstract
Description
technical field
[0001] The invention belongs to the field of downhole equipment, in particular to a device for protecting a turnout connecting rod of a downhole switch. Background technique
[0002] The structural principle of the switch is: the right-angle turn can be rotated at a certain angle, so that one arm of the turn can be moved by a handle, and the other arm is combined with a spring with a certain tension. Under the action of spring tension, according to the principle that the right-angle turn will not stagnate in the middle position, a pull rod is hung on the arm with spring tension, that is, the turnout connecting rod, forming a right-angle turn with a certain traction force at both ends of the rotation angle. Provide power for turnout conversion.
[0003] Except for the installation and withdrawal of the fully mechanized mining face, the auxiliary transportation of a mine is carried by trackless rubber-tyred vehicles. Trackless rubber-tyred vehicles shuttle ba...
Examples
Embodiment 1
[0024] Use a length 500mm*width 350mm*thick δ20mm steel plate to make the connecting rod protective shell 1, open a connecting rod accommodation groove 5, and weld the gravity support rod 2 on its top, and then use a length 700mm*width 550mm*thick δ20mm steel plate to make the top Stress shell 3, and weld the gravity support rod 2, connecting rod protection shell 1 and top stress shell 3 together, lay the processed device on the turnout connecting rod 4, and fix the top stress shell 3 by bolts on the sleeper.
[0025] The market price of a pair of turnout connecting rods 4 is 300 yuan, and there are 6 pairs of turnout connecting rods 4 in the well bottom parking lot. If the present invention is not installed, 30 pairs of turnout connecting rods 4 will be damaged every month, and a pair of turnout connecting rods 4 will be replaced per person every day, and personnel will pay 230 yuan per day, saving 15,900 yuan per month in total.
