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.

Abstract

The invention discloses a device for protecting a turnout connecting rod of an underground switch device, wherein the device comprises a connecting rod protection shell, a gravity support rod, a top stress shell; the connecting rod protection shell is a rectangular shell with an opening at the bottom and has a hollow interior, the opening side of the connecting rod protection shell is used for being buckled on the upper side of a turnout connecting rod and is located between two tracks or on the side of any track. The gravity support rod is arranged vertically and is located on the top of theconnecting rod protection shell. The lower end of the gravity supporting rod is fixedly connected with the top of the connecting rod protection shell, the top stress shell is a rectangular shell withan opening in the bottom and has a hollow interior, the upper end of the gravity supporting rod is fixedly connected with the top of an inner cavity of the top stress shell, the top stress shell is used for being buckled outside the connecting rod protection shell and allowing an underground trackless rubber-tyred vehicle to pass through from the top, and thus the connecting rod protection shell and the turnout connecting rod which are positioned in the inner cavity are further protected; a smooth driving area is provided for the trackless rubber-tyred vehicle, and the situation that the trackless rubber-tyred vehicle rolls the turnout connecting rod, so that the turnout connecting rod is damaged, and normal use is affected is avoided.

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...
