Abstract

The utility model discloses an acoustic-optic signalling device mounted on the top of a fish rod. The fastening nut of the top of a channel-like fishing bell clip is provided with a barrel body for accommodating button shape cells and a spherical shaped water-proof hood for buckling the opening part of the barrel body; a spring guide post is arranged on the upper part of the barrel body. Besides having the advantage of sound indication of the channel-like fishing bell clip without jumping and winding on a sea rod to delay rod lifting time, the acoustic-optic signalling device mounted on the top of the fish rod also has the function of showing light, and thus is particularly suitable for being used in fishing at night.

Description

Remote unload-limited unit for slag vehicle

The utility model relates to the railway slag vehicle and turns over slag automatic spacing control safety guard.

At present the railway slag vehicle that uses is in operation process, often occurs overturn that the position can not return, watt seat bearing grinds and seriously cause the leading screw string to move, do not bend, burn motor, Zang Dao even cause and climb over limit generation car body overthrow accident.

The purpose of this utility model is: provide a kind of railway slag vehicle simple to operate, that avoid Zang Dao and car body overthrow accident take place to turn over slag remote control limiting device.

The utility model by a fixed cover fix, the one end is with spring, the other end stretches out shell, the spacing drive link of the stressed outage plate that can telescopic band moves a step in end, the action of two steps outage switching plate, and limiting device contact, bolt of rear end plate, spacing diode, fixed orifice, teleswitch contact, cable hole are formed, its circuit connecting mode is: the output primary one end ground connection of voltage transformer T, the other end connects relay J ₁J ₂An end, J ₁The other end connect diode D ₁Negative pole, J ₂The other end connect diode D ₂Positive pole, D ₂Negative pole D ₁Positive pole and light-emitting diode D ₃Connect D ₃The other end connect diode D ₄Negative pole, diode D ₅Positive pole, D ₄Positive pole connect a contact of K switch, D ₅Negative pole connect the another one contact of K switch, the swing arm of K switch connects limit switch KK ₂An end, KK ₂The other end connect limit switch KK ₁An end, diode D ₆Positive pole, KK ₁The other end connect D ₆Negative pole, limit switch KK ₃An end, diode D ₇Negative pole, KK ₃The other end connect D ₇Positive pole, limit switch KK ₄An end, KK ₄Other end ground connection.

The utlity model has can remote servicing control, advantage such as easy and simple to handle, safe and reliable.

Fig. 1 is a structural representation of the present utility model;

Fig. 2 is an electrical schematic diagram of the present utility model.

Spacing drive link (1) is fixed in shell (12) inwall by fixed cover (3), one end is inserted in spring (2), is fixed on shell (12) sidewall, the other end be fixed in another sidewall of shell (12), its end protruding, be subjected to pressing after touch that stroke opens the outage plate (5) that moves a step for 10 millimeters, continue 8 millimeters startups of stroke, two step outage plates (4) and finish whole voltage limiting and electricity cutting, among Fig. 1: (6), limiting device contact; (8), spacing diode; (9), teleswitch contact; (10), fixed orifice; (7), bolt of rear end plate; (11), cable hole.Its circuit connects: the output primary one end ground connection of voltage transformer T, the other end connects relay J ₁J ₂An end, J ₁The other end connect diode D ₁Negative pole, J ₂The other end connect diode D ₂Positive pole, D ₁Positive pole and D ₂Negative pole and light-emitting diode D ₃Connect D ₃The other end connect diode D ₄Negative pole and diode D ₅Positive pole, D ₄Positive pole connect a contact of K switch, D ₅Negative pole connect the another one contact of K switch, the swing arm of K switch connects limit switch KK ₂One end, KK ₂The other end connect limit switch KK ₁An end and diode D ₆Positive pole, KK ₁The other end connect D ₆Negative pole, limit switch KK ₃An end and diode D ₇Negative pole, KK ₃The other end connect D ₇Positive pole and limit switch KK ₄An end, KK ₄Other end ground connection.

This device is fixed on two leading screw middle car body of slag vehicle, and the every side in car body both sides is provided with one.

During work, K switch and D ₄Connect D ₃Ruddiness, D ₂By D ₁Conducting J ₁Magnetic starter is connected in adhesive, and actuating current flows through the limiting device make and break contact and constitutes the loop with ground, and slag car inward direction rotates.Touch spacing drive link (1) when the slag car is turned to certain position, spacing drive link (1) regression backward opens the outage plate (5) that moves a step, diode D for 10 millimeters ₆Work makes D ₄D ₁Diode reverse by and stop the slag car and continue upset.In case diode D ₆Puncture the get out of hand effect slag car and continue upset, spacing drive link (1) then continues to retreat 8 millimeters and starts two steps outage plate (4), forces limit switch KK ₂Cut off working power, carry out and force safety guard-safeguard for the second time.

When K switch and D ₅During connection, D ₃Green glow, D ₁End and D ₂D ₆Conducting J ₂Adhesive work, the slag car are at this moment to backward rotation, and the working spring (2) on the spacing drive link (1) then recovers playback automatically.
