Abstract
A cable-suspended device for falling prevention on a transmission tower is formed by a clamping mechanism fixed on the tower and a damper; the damper comprises a sleeve which can be vertically and fixedly connected on the clamping mechanism and a hoisting ring capable of performing lengthways displacement relative to the sleeve and used for being fixedly connected with the cable. The damper is arranged in the device, the cable is fixedly connected to the ring-shaped hook of the damper, a cable locking device is sleeved on the cable and the other end of the cable locking device is tied to the waist of a climbing person through a rope, and a spring is arranged in the sleeve of the damper, so that when the person accidentally falls, the elasticity of the spring ensures that a buffering force generated by the cable can avoid the serious hurt to the waist of the person in case of sudden falling.
Description
Technical field:
The utility model relates to and is used for anti-fall rope suspension arrangement on a kind of electric force pole tower.
Background technology:
In sending the high-altitude work progress of electric overhead transmission line shaft tower; the capital relates to workmen's safeguard protection; the staff usually was free-hand climbing shaft tower and following shaft tower in the past; there is not effective safety prevention measure; in case accidentally drop or step on cunning; hardly imaginable serious consequence will take place; cable wire of suspention above shaft tower is also arranged in the prior art; when the staff climbs the rope Locking device of an end bolt at waist is enclosed within on the cable wire; when in case falling accident takes place; rope Locking device is locked on the cable wire immediately; can play a protective role to the staff; but because cable wire is rigid the connection with shaft tower, cable wire did not have cushion effect when the staff fell, and therefore easy waist to the staff causes bigger injury.
The utility model content:
For overcoming the defective of prior art; the purpose of this utility model is to provide a kind of anti-fall rope suspension arrangement that is used for that forever is installed on the shaft tower; when the dangerous situation that the generation personnel fall; can make the cable wire stroke of one section buffering of operation downwards; staff's waist is played the effect of protection; this device has the safety coefficient height, characteristics with low cost, easy to use.
The utility model technical solution problem adopts following technical scheme:
Be used for anti-fall rope suspension arrangement on the electric force pole tower, described suspension apparatus is made of the clamping device and a buffer that can be fixed on the shaft tower, and described buffer comprises the sleeve that vertically connects firmly on clamping device and can form with the suspension ring that are used to connect firmly cable wire of the vertical relative displacement of sleeve.
Design feature of the present utility model also is:
The vertical rod of described suspension ring is positioned at sleeve, and socket one spring in the vertical rod sets firmly a spring pedestal in the bottom of sleeve, and vertical rod top thread segment is connected with the nut that can make the spring top base.
Described clamping device comprises first steel plate of " L " shape that the sleeve with buffer connects firmly and is second steel plate of " L " shape that the level stack is provided with first steel plate, the correspondence position of first steel plate and second steel plate offers the waist hole, and by the fastening bolt that interts in the waist hole first steel plate and second steel plate is linked together.
The top that is positioned at described nut in described vertical rod radially offers pin hole, is plugged with to prevent that nut breaks away from the latch of vertical rod in pin hole.
Compared with the prior art, the beneficial effects of the utility model are embodied in:
1, the utility model is by being provided with a buffer, cable wire connects firmly on the annular hook of buffer, rope Locking device is socketed on the cable wire, the other end of rope Locking device is by the waist of rope bolt the climbing personnel, in the sleeve of buffer, be provided with spring, when dangerous situation that the generation personnel fall, by the elastic force effect of spring, can make cable wire produce the strength of a buffering, when avoiding falling suddenly waist be caused serious injury because of personnel.
2, the utility model top of being positioned at described nut in vertical rod radially offers pin hole, patches pin in the pin hole interpolation, can prevent effectively that further nut breaks away from from vertical rod, for climbing personnel's personal safety further provides guarantee.
3, the utility model is the permanent anti-falling facility that is fixed on the shaft tower, needn't snap or holes shaft tower, therefore can not produce new potential safety hazard to shaft tower; The utility model is simple in structure, and is flexible to operation, and the staff easily grasps use, has very large safe value, and installs easily, has versatility.
Description of drawings:
Fig. 1 is a structural representation of the present utility model.
Figure 1A is that the A-A of buffer is to cutaway view Amplified image.
Fig. 2 is the structural representation of the utility model second embodiment.
Number in the figure: 1 clamping device, 11 first steel plates, 12 second steel plates, 13 waist holes, 14 fastening bolts, 2 buffers, 21 sleeves, 22 suspension ring, 23 vertical rods, 24 springs, 25 spring pedestals, 26 nuts, 27 latches, 3 cable wires, 4 " U " shape bolt.
Below pass through the specific embodiment, and the utility model is described in further detail in conjunction with the accompanying drawings.
The specific embodiment,
Non-limiting examples is as described below:
Embodiment 1: referring to Fig. 1, Figure 1A, be used for anti-fall rope suspension arrangement on the electric force pole tower, suspension apparatus is installed on the angle steel of shaft tower cat ladder top, constitute by two parts, can be fixed on a clamping device 1 and a buffer 2 on the shaft tower, buffer 2 comprises the sleeve that vertically connects firmly on clamping device 1 21 and can form with the suspension ring 22 that are used to connect firmly cable wire 3 of the vertical relative displacement of sleeve.The vertical rod 23 of suspension ring 22 is positioned at sleeve 21, and socket one spring 24 in the vertical rod 23 sets firmly a spring pedestal 25 in the bottom of sleeve, and vertical rod top thread segment is connected with the nut 26 that can make the spring top base.Nut 26 breaks away from from vertical rod 23 in order to prevent of long duration, the top that is positioned at described nut in vertical rod 23 radially offers pin hole, in pin hole, be plugged with latch 27, can prevent effectively that nut 26 breaks away from vertical rod 23, thereby further ensured climbing personnel's personal safety.
During use; this device is installed on the angle steel of the shaft tower above the cat ladder; during installation; unclamp fastening bolt 14 earlier; second steel plate 12 takes off from first steel plate 11; first steel plate is fastened on the angle steel of shaft tower; again second steel plate 12 is fastened on the opposite side of angle steel; can be fixed on the shaft tower by this device by fastening bolt 14 lockings, cable wire 3 connects firmly on the suspension ring 22 of annular, and the climbing personnel are enclosed within rope Locking device known in the art on the cable wire 3; the rope Locking device other end passes through the rope bolt on waist; when dangerous situation that the generation personnel fall, the rope Locking device auto lock is on cable wire 3, and at this moment cable wire is subjected to a rapid downward power; spring is compressed; play the effect of buffering, avoided causing serious injury to waist, the staff is had good protective effect because of human body falls suddenly.
