Abstract
The utility model relates to a cable shaft anti -falling device, including establishing the protection frame above the power cable in weight net and the well of preventing at the well head. The utility model discloses take the well head to prevent weight protection and well head below cable and prevent weighing down the mode that combines together of protecting, improve cable run's fail safe nature, avoided most pedestrians to weigh down the social dispute that the well incident arouses from this, ensured simultaneously that cable run's safe and reliable moves.
Description
Technical field
The utility model relates to a kind of falling proof device, is specifically related to a kind of cable shaft anti-fall device, for the fall arrest protection of cable shaft.
Background technology
In recent years, since, along with the enlarging of Changsha District and riseing of power load, the utilization rate of power cable rises year by year. At present, the main distribution network cable well of Changsha electric company jurisdiction has more than 10000, wherein often has every year hundreds of place cable manhole cover damage or loss, occasionally has pedestrian, bicycle, electric motor car pendant well event to occur. And because exist a large amount of cables to be positioned at the situation under well head, also occurred that well lid or foreign body fell in well, caused the situation of cable fault.
According to " 18 great anti-accident measures of electrical network of State Grid Corporation of China " 13.3.2.2 article of regulation: the cable under work well, should take the safeguard measure that prevents that dropped object from hitting. But how " 18 counter arranging " and undeclared this of other Regulations take anti-falling protection measure, at present the power industry of Changsha city is also there are no the application of such measure.
Through investigation, have at rain sewage well mouth the application of anti-drop net of installation, but this anti-drop net prevents that personnel from falling well while only considering manhole cover loss. And for electric power well, the personnel that not only will prevent fall well, also to protect the power cable of well head below.
Utility model content
The purpose of this utility model is to provide a kind of cable shaft anti-fall device, and the personnel that can prevent fall well, also can protect the power cable of well head below.
The technical solution of the utility model is: a kind of cable shaft anti-fall device, comprises and be located at the anti-drop net of well head and the protective frame of the interior power cable of well top.
Described cable protective frame comprises dismountable two parts: the base of support and below thereof, support comprises frame top.
Further, frame top is two top boards, and two top boards intersect formation one pinnacle. Preferably, two top boards and horizontal plane become identical angle, join at the horizontal center line place of support.
Further, described top board is PLASTIC LAMINATED.
Further, base is provided with installing hole, to be arranged on shaft bottom.
Further, be fixed with sleeve on base, the bottom column of support inserts in sleeve.
Further, sleeve is provided with buffer spring outward, and making has one section of buffer distance between bottom column and base. The base cross members of support is withstood in buffer spring upper end, and base is withstood in lower end.
For manhole cover damage or fall in well the potential safety hazard of bringing to operating power cable and pedestrian, the utility model is taked well head anti-falling protection (anti-drop net) and mode that below well head, cable anti-falling protection (cable protective frame) combines. Well head anti-falling protection part is durable, corrosion-resistant, it is stolen to be difficult for, and at least can be subject to an adult's weight. Well head below cable anti-falling protection part has certain anti-strike capability, possesses the power of letting out function, thereby improve anti-strike capability in alleviator weight.
Adopt fall arrest protection of the present utility model, the personnel that can not only prevent fall well, and can prevent that object pendant well from hitting cable and causing cable impaired, specifically:
1) when manhole cover damage or when disappearance, install the mode of anti-drop net by well head, can prevent that falling object from falling in well and injure cable by a crashing object, it is interior injured that the personnel of preventing crash into well;
2) in the time opening and cover well lid and accidentally make well lid slippage, by the mode of anti-strike stand (cable protective frame) is installed above cable, avoid well lid to fall in well, even or fall in well, be also unlikely to injure by a crashing object cable;
3), in addition in the time that anti-drop net lost efficacy, the power cable that also can prevent from being positioned under well head overwhelms;
4) this device also can prevent from directly trampling when workmen from passing in and out cable shaft cable.
Thereby improve the security reliability of cable run. Avoid thus most pedestrians to fall the Social Dispute that well event causes, ensured the safe and reliable operation of cable run simultaneously. In addition, this device also should be convenient to install, dismounting, and anti-strike gantry designs is knock-down two parts, the not impact personnel maintenance of going into the well.
Brief description of the drawings
Accompanying drawing 1 is the front view of the cable protective frame of a detailed description of the invention of the utility model;
The side view that accompanying drawing 2 is Fig. 1;
Accompanying drawing 3 is base vertical view in Fig. 1;
Wherein, PLASTIC LAMINATED 1, support 2, base 3, sleeve 4, buffer spring 5, bottom column 21, base cross members 22.
Detailed description of the invention
The utility model is realized Double falling-prevention by well head anti-drop net and cable protective frame, specifically:
1, cable protective frame
As shown in Fig. 1 ~ 3, cable protective frame entirety adopts dismountable two large divisions, and a part is that support 2(comprises frame top), another part is base 3. Support 2 adopts the angle steel of 40 × 40 × 5mm to be welded. Support 2 is in the load-bearing of welded top triangularity frame.
Support 2 tops adopt two thick PLASTIC LAMINATEDs 1 of 10mm to form, and two 30 degree oblique angles that PLASTIC LAMINATED 1 becomes with horizontal plane, join at center line, and the roof type high in the middle of forming, both sides are low, can produce certain buffering effect. PLASTIC LAMINATED 1 is fixed on support 2 tops by self-tapping screw, forms an entirety.
Welded sleeve 4 on the base 3 of stand, the bottom column 21 of support can insert in sleeve 4, and between bottom column 21 and base 3, without being fixedly connected with, support 2 and the PLASTIC LAMINATED 1 of device the first half can up be mentioned dismounting, the not impact personnel maintenance of going into the well.
The outer damping spring 5 that installs additional of sleeve 4, damping spring 5 is between frame bottom crossbeam 22 and base 3, not stressed when compressed at damping spring 5, support 2 and base 3 keep certain buffer distance, fall into reduce weight the impulsive force of bringing to device in well, further strengthened the protecting against shock ability on frame top. Base 3 is fixed on shaft bottom by setscrew.
2, well head anti-drop net
Anti-drop net is selected the nylon rope anti-drop net detecting by national correlation department, and mesh is 10 × 10cm. Nylon rope anti-drop net has high strength, corrosion resistant characteristic, and its value that is recycled is low, conventionally can not be stolen.
In the boring of cable shaft well head inwall, the reinforcing bar that is setscrew by 10 one end hook is evenly fixed on well head inwall, and hook gos deep into borehole wall length and is not less than 5cm, ensures to link up with and installs firmly, and it is upper that anti-drop net hangs over hook, and it is convenient to install and remove.
