Abstract
The utility model discloses a handheld rotary type slow-descent control device and relates to the technical field of slow-descent rescuing tools for accidents occurring during electric transmission line working at heights. The device comprises a hook, a draw-bar ring, a rope, a speed slow-descent controller and a portable equipment bag, wherein the speed slow-descent controller comprises a shell body, two or more rope sheaves, a handle, a pressing plate and a control bolt, the rope sheaves are mounted on the upper portion of the interior of the shell body, the handle is movably connected to the lower portion of the interior of the shell body, the pressing plate is arranged on the side, close to the rope sheaves, of the handle, the control bolt is in coaxial connection with the handle, the rope is wound around the rope sheaves, and the hook, the draw-bar ring, the rope and the speed slow-descent controller are all placed in the portable equipment bag. The handheld rotary type slow-descent control device aims to solve the problem that according to a traditional rescuing method, the number of rescuing staff on a tower is large, rope drawing is hard to achieve, and the descent speed and position of the wounded are hard to control, and is suitable for being used for high-altitude rescuing when accidents such as personnel falling or electric shocks occur.
Description
Technical field
The utility model relate to a kind of from building or analog device use for taking people downstairs, relate to the slow rescue tool technical field of falling of transmission line high-altitude work accident.
Background technology
In ultra-high-tension power transmission line maintenance repair operation, because personnel's misoperation, equipment operation condition are not good, the reasons such as external environment influence, easily cause the personal injury accidents such as operating personnel's falling from high altitude, electric shock injure, junk is hurted sb.'s feelings.Wherein, falling from high altitude and electric shock injury accident often cause operating personnel to be suspended in high-altitude or are suspended on shaft tower, not only the wounded itself are caused compared with major injury, also bring very big inconvenience to rescue action simultaneously.The current rescue mode for personnel on tower, conventionally take rescue personnel to carry common rope and step on tower, arrive behind wounded position, rope knotting is tied up to it the wounded, by personnel, pull rope wounded's slow decreasing is rescued to ground, this mode needs on tower rescue personnel's quantity more, and pull rope and comparatively require great effort, the wounded are slow, and reduction of speed degree cannot effectively be controlled, and rescue program is numerous and diverse, time is tediously long, is unfavorable for bailout development.
Utility model content
For overcoming the drawback of traditional rescue mode, solve the rescue problem after work high above the ground personnel have an accident, the purpose of this utility model is to provide a kind of novel structure, it is ingenious to design, rescue in time, install easy to carry, performance safety reliable, convenient operation hold the rotary slow control device that falls.
The technical scheme in the invention for solving the above technical problem is:
Hold rotary delaying and fall a control device, it is characterized in that, comprise hook, draw-barring, rope, the slow drop controller of speed and portable general purpose bag; The slow drop controller of described speed comprises housing, rope sheave, handle, pressing plate, control bolt; Rope sheave is arranged on enclosure interior top, quantity be made as 2 and more than; Handle is movably connected in enclosure interior below, and pressing plate is located at handle by rope sheave side; Controlling bolt is coaxially connected with handle; Rope is wrapped on rope sheave, hook, draw-barring, the slow drop controller unification of speed that winds rope can be packed in portable general purpose bag at ordinary times, and convenient working personnel carry and handling instrument.
Described handle and clamp surface are equipped with Z-Correct bump mapping Z-correct, as surface knurling or roll threading, can effectively increase rope frictional force, make rope speed obtain better manual control.
Described rope sheave quantity is made as 4, on-the-spot use slow fall respond well.
Adopt the beneficial effect that technique scheme produces to be: it is more that the utility model has solved in traditional rescue mode on tower rescue number effectively, it is painstaking that personnel pull rope, the problems such as wounded's sinking speed and Position Control difficulty, and have that project organization is simple, rescue rapidly in time on tower, slow the falling of the wounded control effectively, install the advantages such as easy to carry, dependable performance, fitting operation are convenient, when being applicable to being applied in generation personnel and falling or get an electric shock the accidents such as injury, needs carry out in the operation of height rescue.
Accompanying drawing explanation
Below in conjunction with the drawings and specific embodiments, the utility model is described in further detail.
Fig. 1 is the slow drop controller of the speed in the utility model embodiment.
Fig. 2 is the hook in the utility model embodiment.
Fig. 3 is the coupling ring in the utility model embodiment.
Wherein: 1, housing, 2, rope sheave, 3, handle, 4, pressing plate, 5, control bolt, 6, hook, 7, coupling ring, 8, rope.
The specific embodiment
Embodiment 1(is shown in Fig. 1), in the present embodiment, link up with the flat hook of 6 employing list rope annulus, draw-barring 7 adopts single rope simple type circle hook, convenient and practical, rope 8 is the special-purpose rope of mountain-climbing, and softness is light, mechanical strength is high, wear-resistant, insulation can be good, and portable general purpose bag is common electrician's kit bag; In the slow drop controller of speed, rope sheave 2 quantity are made as 4, are wound around, friction effect is better; Rope 8 is wrapped on rope sheave 2 in advance, handle 3, pressing plate 4 surfaces are rolled thread all, handle 3 ends change arc bending upwards type into by straight formula, further strengthen friction dynamics, then hook 6, draw-barring 7, the slow drop controller of speed that winds rope 8 are contained in common electrician's kit bag in the lump.
During use, operating personnel hang over hook 6 on the firm member of shaft tower, rope 8 one end are fixed on hook 6, as the slow stressed suspension centre that falls the wounded, utilize draw-barring 7, the slow drop controller of speed is connected with wounded's safety belt, as the stressed node being connected between rope 8 and the wounded, frictional force effect by rope sheave 2 makes the stressed clamping of rope 8, then operating personnel hold handle 3 pressing plate 4 are pressed in rope sheave 2 grooves, pressing plate 4 and rope 8 are further compressed, then screw control bolt 5, compress rope 8.Because frictional force increases, the slow reduction of speed degree of rope 8 is controlled, the difference when pressing plate 4 positions like this, the frictional force that rope 8 is subject to is also by difference, and slow reduction of speed degree obtains manual control, and the wounded are from the slow ground that falls of shaft tower the most at last, only need 1-2 people, can realize the wounded's height rescue.
Because the utility model design has adopted technique scheme, effectively solved in traditional rescue mode on tower rescue number more, it is painstaking that personnel pull rope, the problems such as wounded's sinking speed and Position Control difficulty, and have that project organization is simple, rescue rapidly in time on tower, slow the falling of the wounded control effectively, install the advantages such as easy to carry, dependable performance, fitting operation are convenient, when being applicable to being applied in work high above the ground generation personnel and falling or get an electric shock the accidents such as injury, needs carry out in the operation of height rescue.
