Abstract
The utility model relates to a releasing alarm earth wire clip, which belongs to power transmission job safety tools, and solves the technical problem that the earth wire is connected with the ground at the working area when power cut operation, wherein, an earth terminal is composed of a hook head (1), a hook body (5), an earth terminal line (11) and an electric alarm (8); the lower end of the hook body (5) is 'H'-shaped and is hinged with the hook head by a hinged shaft; in the middle part, two corresponding semi-circle jaws (7) form a floating open jaws (6) to clamp the earth wire. The utility model has the advantages that the releasing alarm earth wire clip can be attached and detached freely; the load current is large; the electric shock hazard is alarmed; the safety of persons and devices is guaranteed when an earth wire is installed.
Description
The utility model belongs to the electric job safety instrument, particularly a kind of release type warning earthing clamp hook at the power transmission sequence construction operation of sending.
The earth clamp that uses on the electric power tool power transmission sequence at present is clamping plate type, the normal angle body that takes place becomes flexible, because the power transmission sequence spacing is bigger, the operating personnel is difficult for installing, is difficult to be installed on the lead, mostly is lodge with lead and connects, because ground wire and lead contact area are little, when short circuit takes place, cause the lead scaling loss, influence the person and device security.
The purpose of this utility model is to overcome above technical deficiency, and a kind of release type warning earthing clamp hook of safety work is provided.
Task of the present utility model is, release type alarm earthing clamp hook is by earth terminal, earth clamp is by the grab head, and the grab body is formed, and the ground connection end line of the ground wire connection holes on the grab body is by screw, at opening part electric alarms based on pattern recognition is installed, grab body lower end is that " H " type is hinged by jointed shaft with the grab head, and both sides articulate axis, extension spring, forms the open type jaw that floats at central part by two corresponding semicircle mismatch, clamp earth connection, the grab head is the circular arc gib head.There is electric alarms based on pattern recognition to send acoustic signal automatically, the user carried out Danger Electric shock risk report to the police.
Release type warning earthing clamp hitcher has following characteristics, and 1, earth connection is 25mm
2, 35mm
2Plastic sheath is the multiply annealed copper wire, installs single-phase earthing and three-phase shortcircuit ground connection respectively; 2, ground wire termination mounting or dismounting freely, gib head jaw grip force is 10～20kg, with the lead contact area be 8cm
2, it is big to bear electric current, contacts with lead firmly; 3, operation is efficient and convenient, can articulate, install suspension hook on lead and shaft tower; 4, increase has electric alarms based on pattern recognition, plays the protective effect of safety work.
Specify with embodiment below in conjunction with accompanying drawing
Fig. 1 shows release type alarm earthing clamp hook structure.
Fig. 2 shows release type alarm earthing clamp hook profile.
Fig. 3 shows release type alarm earthing clamp hook left view.
Fig. 4 shows folder coupler body profile.
Fig. 5 shows release type alarm earthing clamp hook left view.
Fig. 6 is shown with telegram and respects the device circuit theory diagrams.
1-grab head among the figure; The 2-extension spring; The 3-axis; The 4-jointed shaft; 5-grab body; The 6-open type jaw that floats; 7-half figure jaw; 8-has electric alarms based on pattern recognition; 9-ground wire connection holes; 10-connects screw; 11-ground connection end line.
Fig. 1 is a release type alarm earthing clamp hook structure, by earth terminal, the release type warning earthing clamp hook that earth clamp is formed, earth clamp is by grab head (1), grab body (5) is formed, the ground connection end line (11) of the ground wire connection holes (9) on grab body (5) is fixing by screw (10), at opening part electric alarms based on pattern recognition (8) is installed, grab body (5) lower end is that " H " type is hinged by jointed shaft (4) with grab head (1), both sides articulate axis (3), extension spring (2), form the open type jaw (6) that floats at central part by two corresponding semicircle jaws (7), clamping earth connection grab head (1) upper end is the circular arc gib head.
Have the sounder Y of electric alarms based on pattern recognition (8) to be made by the buzzing sheet, antenna F twines with the 0.35mm plastic coated wire, and an end is unsettled, and a termination is gone into field effect pipe V
2, power supply adopts direct current 3V lithium battery, self-test switch K
1With sensitivity selecting switch K
2All adopt sensitive switch, insert the pressing plate plastic pressure forming by lead.
Release type warning earthing clamp hook is by the high-strength aluminum alloy compression molding, and earth connection adopts 25mm
2, 35mm
2The multiply annealed copper wire applies the anti-frozen glue of protection, ground connection type behind employing SFBJD-220KV single-phase earthing type and the SFBJD-66KV three-phase shortcircuit.The earthing clamp hook by grab head (1), grab body (5), have electric alarms based on pattern recognition (8) three parts to form, press self-test switch K during use
1, sounder Y just sends acoustic signal, and to be considered as electric alarms based on pattern recognition (8) working properly, with self-test switch K
1Pull out back original position, press sensitivity selecting switch K
2Select working range.The grab both sides connect 2 tension springs (2), hang on the lead to get final product, and only need 20Kg left and right sides impulsive force to come off voluntarily during dismounting.Earth connection and shaft tower contact portion use the fixed by nut of φ 16 on the bolt of shaft tower.Under the 10KV line voltage distribution, when the user apart from the original position of the 1.3M of supply line or user under the 35KV line voltage distribution during apart from the original position of the 3.4M of supply line, there is electric alarms based on pattern recognition (8) to produce output signal, the warning electric current is less than 1uA, and sounder Y piezo is sent acoustic signal the user is carried out the Danger Electric shock risk warning.Guarantee the security reliability of ground connection according to " electric industry safety regulations ", avoid external impacts and come off.
The key property of release type warning earthing clamp hook
| Loaded current (A) | Vertical load (hold and put forth effort) KG | Lead is suitable for cross section mm 2 | Maximum contact wire glass mm 2 | Contact wire girth % | Stressed KG is installed | Stressed KG during dismounting | Warning device and lead degree throw are from m |
| 8000 | 50 | 95-300LCJQ | 1200 | ＞90 | ≥15 | ≤20 | 3.5-4.0 |
Release type warning earthing clamp hook has solved the technical problem of power failure operation at job site two ends hanging earthing conductor, earth connection installing, dismounting are conveniently, there is electric alarm device sounding reliable, guarantees the safety of installing earth connection, have practicality and promotional value the person and equipment.
