轉(zhuǎn)轍機(jī)是指用以可靠地轉(zhuǎn)換道岔位置,改變道岔開(kāi)通方向,鎖閉道岔尖軌,反映道岔位置的重要的信號(hào)基礎(chǔ)設(shè)備,它可以很好地保證行車安全,提高運(yùn)輸效率,改善行車人員的勞動(dòng)強(qiáng)度。
作用
(1)轉(zhuǎn)換道岔的位置,根據(jù)需要轉(zhuǎn)換至定位或反位;
(2)道岔轉(zhuǎn)至所需位置且密貼后,實(shí)現(xiàn)鎖閉,防止外力轉(zhuǎn)換道岔;
(3)正確地反映道岔的實(shí)際位置,道岔的尖軌密貼于基本軌后,給出相應(yīng)的表示;
(4)道岔被擠或因故處于“四開(kāi)"(兩側(cè)尖軌均不密貼)位置時(shí),及時(shí)給出報(bào)警及表示。
Switch machine refers to the important signal equipment used to reliably change the position of the switch, change the opening direction of the switch, lock the switch rail, and reflect the position of the switch.
Effect
(1)Switch the position of the switch to position or reverse as required;
(2)After the switch change to the required position, lock it, and avoid it being converted with the external force;
(3)It correctly reflects the actual position of the switch. The switch's pointed rail is closely attached to the basic rail, and corresponding representation is given.
(4)When the switch is crashed or is in the position of "four open" (two side rails are not closed tightly), the alarm and signal shall be given in time.
