Abstract
The utility model relate to an attention device for the locking state of a telescopic upper body of a derrick, belonging to the technical field of derricks. The attention device comprises an approach switch (5) and the like, when the derrick upper body (1) is fixed or can not extend in place, a red light (8) of an acousto-optical warning device turns on, and a green light (7) of the acousto-optical warning device turns off. When the upper body extends to a preset height, and a lock pin device (2) is in place and opens, the approach switch (5) provides an electric signal to a circuit system to control an intermediate relay (9) to be actuated, the green light (7) of the acousto-optical warning device turns on, and the red light (8) of the acousto-optical warning device turns off. The attention device can realize real-time monitoring on the stretching position of the derrick, and is convenient in operation, and accurate and safe.
Description
One, technical field:
The utility model is the flexible upper body of an a kind of derrick lock-out state alarming device, belongs to the derrick technical field.
Two, background technology:
Judged in the past the derrick upper body is stretched out when whether putting in place, the sound that often adopt perusal, sends when auxiliary tin derrick carrier block stretches out is again judged.The method of this observation often needs operating personnel that rich practice experience is arranged, and inaccurate dangerous.Original method can't satisfy the requirement that the actual use in oil field is arranged.
Three, summary of the invention:
The utility model is at the problem that can't accurately judge whether in the telescopic process of existing derrick upper body to put in place, has designed a kind of device whether derrick upper body latch gear puts in place that is used for accurately monitoring.This alarming device is applicable to the suit derrick of various models.The technical scheme that the utility model is taked is: the derrick alarming device that stretches, by forming near switch (5) etc., it is characterized in that anti-explosion terminal box (6) is fixed on the derrick carrier bar, be fixed on the anti-explosion terminal box (6) near switch (5), auxiliary reclay (9), acoustic-optic alarm green light (7), acoustic-optic alarm red light (8) are fixed on the position of being convenient to observe.
The utility model is like this work, and fixing or stretch out when not in place in derrick upper body (1), acoustic-optic alarm red light (8) is bright, and acoustic-optic alarm green light (7) goes out.Stretch out when the upper body and to arrive that predetermined altitude latch gear (2) puts in place and when opening, can offer signal of telecommunication of Circuits System near switch (5), the adhesive of control auxiliary reclay (9), acoustic-optic alarm green light (7) is bright, and acoustic-optic alarm red light (8) goes out.The utility model can be realized the real-time monitoring of derrick telescopic location, and is easy to operate, accurately safety.
Four, description of drawings:
Accompanying drawing 1 is the utility model scheme of installation
Accompanying drawing 2 is the local enlarged diagram of the utility model
Among the figure: 1, derrick upper body; 2, latch gear; 5, near switch; 6, anti-explosion terminal box; 7, acoustic-optic alarm green light; 8, acoustic-optic alarm red light; 9, auxiliary reclay.
Five, the specific embodiment:
Embodiment 1, a kind of novel derrick upper body stretching device that is used to monitor, by forming near switch (5) etc., anti-explosion terminal box (6) is fixed on the derrick carrier bar, be fixed on the anti-explosion terminal box (6) near switch (5), auxiliary reclay (9), acoustic-optic alarm green light (7), acoustic-optic alarm red light (8) are fixed on the position of being convenient to observe.
Claims (1)
1. the flexible upper body of derrick lock-out state alarming device, by forming near switch (5), it is characterized in that anti-explosion terminal box (6) is fixed on the derrick carrier bar, be fixed on the anti-explosion terminal box (6) near switch (5), auxiliary reclay (9), acoustic-optic alarm green light (7), acoustic-optic alarm red light (8) are fixed on the position of being convenient to observe.
