Description
Technical field
The utility model relates to electric power overhaul field of tool, especially relates to a kind of rope ladder ground fixer with anti-thorn.
Background technology
In transmission line of electricity Ordinary Work and service work, often need to adopt rope ladder to carry out operation, rope ladder lower end is fixed, being convenient to operating personnel utilizes rope ladder to climb, if rope ladder lower end is fixed bad, work high above the ground personnel can swing on rope ladder, affect job safety.Existing software ground fixer is fixing unstable in use, is easily drawn out; During use, if rope ladder draw too tight, circuit is easily damaged in the process of maintenance; If the too pine that rope ladder draws, easily cause the staff on rope ladder to swing, there is potential safety hazard.
Utility model content
The purpose of this utility model is to provide a kind of rope ladder ground fixer, to solve because not firm caused security hidden trouble fixed by rope ladder.
For achieving the above object, the technical solution adopted in the utility model is:
With a rope ladder ground fixer for anti-thorn, comprise T-shaped intubate, thorn axle and inverted U buffer bar; Described T-shaped intubate comprises bracing frame and thorn pipe; The two ends of support frame as described above are provided with buffer bar through hole, and spinosity pipe through-hole is offered at middle part; The lower end of described thorn pipe is provided with inserts cone, and thorn pipe upper end is fixedly connected with bracing frame; Described thorn pipe is between described buffer bar through hole; It is inner that described thorn axle stretches into thorn pipe by thorn pipe through-hole, and the middle and upper part of thorn axle is connected with thorn gas thread, and thorn axle middle and lower part is hinged with anti-thorn, and the thorn pipe of anti-thorn corresponding position is provided with thorn mouth, and it is outside that anti-thorn stretches out thorn mouth; Described thorn axle upper end is welded with swing handle, and swing handle is positioned at above support frame as described above; Described two vertical bars are each passed through buffer bar through hole, and vertical bar bottom is fixed with catch, and the vertical bar between catch and bracing frame is arranged with spring; Described anti-thorn is receiving state when being less than 15 degree with the angle of thorn axle, is stationary state when angle is greater than 85 degree and is less than 90 degree.
As preferably, the cross bar of described buffer bar is provided with the collar.
As preferably, described thorn axle middle and lower part is hinged with two anti-thorns, two anti-thorn be positioned at thorn axle differing heights, the thorn pipe of corresponding position is equipped with thorn mouth, and it is outside that two anti-thorns all stretch out thorn mouth.
A kind of rope ladder ground fixer with anti-thorn of the present utility model has following advantage: described thorn pipe is between two buffer bar through holes of bracing frame, add the spacing between two springs, expand buffering lifting surface area, the pulling force of fixator can be made more moderate, make the use that rope ladder can be more reliable and stable; Described thorn axle lower end is hinged with anti-thorn; During receiving state, fixator is squeezed in earth by constructor, reduces because using anti-thorn to the extra resistance increased of thorn pipe; After thorn pipe is squeezed into earth certain depth, rotating swing handle can mention thorn axle, and makes instead to sting to open to stretch in earth, and playing firmly fixation, is now stationary state; After finishing using, reversely rotate swing handle, can pack up instead stinging, finally again fixator firmly being mentioned withdrawal.The utility model structure is simple, easy to use.
Accompanying drawing explanation
Fig. 1 is that the utility model has a structural representation instead stung;
Fig. 2 is that the utility model has two structural representations instead stung.
Detailed description of the invention
embodiment one
Below in conjunction with accompanying drawing, the utility model is described in further detail:
As shown in Figure 1, the utility model comprises T-shaped intubate, thorn axle 2 and inverted U buffer bar 5; T-shaped intubate comprises bracing frame 8 and thorn pipe 1; The two ends of bracing frame 8 are provided with buffer bar through hole 11, and spinosity pipe through-hole 13 is offered at middle part; The lower end of thorn pipe 1 is provided with slotting cone 4, and thorn pipe 1 upper end is fixedly connected with bracing frame 8; Thorn pipe 1 is between buffer bar through hole 11; It is inner that thorn axle 2 stretches into thorn pipe 1 by thorn pipe through-hole 13, and the middle and upper part of thorn axle 2 is threaded with thorn pipe 1, and thorn axle 2 middle and lower part is hinged with anti-thorn 3, and the thorn pipe 1 of anti-thorn 3 corresponding positions is provided with thorn mouth 12, and it is outside that anti-thorn 3 stretches out thorn mouth 12; Thorn axle 2 upper end is welded with swing handle 9, and swing handle 9 is positioned at above bracing frame 8; Two vertical bars are each passed through buffer bar through hole 11, and vertical bar bottom is fixed with catch 7, and the vertical bar between catch 7 and bracing frame 8 is arranged with spring 6; The cross bar of inverted U buffer bar 5 is provided with the collar 10; Anti-thorn 3 is less than or equal to 90 degree with the angle range of movement of thorn axle 2, and being receiving state when angle is less than 15 degree, is stationary state when angle is greater than 85 degree and is less than 90 degree.
In use, will terminate on the collar 10 under rope ladder, and when the utility model is receiving state, squeeze in earth with instruments such as sledgehammers by this device, anti-thorn 3 keeps parallel longitudinal with thorn pipe 1 under the effect of earth, and squeezes into certain degree of depth.Rotate swing handle 9 again, anti-thorn 3 will rotate with thorn axle 2, after rotating a fixing turn, because the anti-movable end stinging 3 is positioned at the outside of thorn mouth 12 all the time, along with the hinged end of anti-thorn 3 rises, under the position-limiting action on the movable end of anti-thorn 3 edge on thorn mouth 12, anti-thorn 3 opens and stretches in earth, make the angle of anti-thorn 3 and thorn axle 2 close to or reach 90 °, it is now stationary state, can play firmly fixation to rope ladder, and spring 6 can play cushioning effect, and the pulling force of fixator can be made moderate.After finishing using, swing handle 9 is rotated by contrary direction, anti-thorn 3 will rotate with thorn axle 2, along with the decline of anti-thorn 3 hinged end positions, anti-thorn 3 movable end can sting counter 3 and packs up under the position-limiting action on thorn mouth 12 times edges, get back to anti-thorn 3 receiving state or close to receiving state, then this device is firmly mentioned withdrawal.
embodiment two
As shown in Figure 2, with embodiment one unlike the middle and lower part of, thorn pipe 1 be hinged with two anti-thorn 3, two anti-thorn 3 be positioned at thorn axle 2 differing heights place, the thorn pipe 1 of corresponding position is equipped with thorn 12, two, mouth anti-thorn 3 all to stretch out thorn mouth 12 outside.After this device is squeezed into earth certain depth, rotate swing handle 9 thorn axle 2 to be mentioned, two are instead stung 3 and rotate together along with stinging axle 2, after rotating a fixing turn, the movable end instead stinging 3 due to two is positioned at the outside stinging mouth 12 all the time, the hinged end instead stinging 3 along with two rises, two are instead stung the movable end of 3 under the position-limiting action stinging edge on mouth 12, two are instead stung 3 and open and stretch in earth, make two anti-thorn 3 and thorn axle 2 angle all close to or reach 90 °, it is now stationary state, more firmly fixation can be played to rope ladder under two anti-thorn 3 effect simultaneously, and spring 6 plays cushioning effect, the pulling force of fixator can be made moderate, after finishing using, swing handle 9 is rotated by contrary direction, under the position-limiting action on thorn mouth 12 times edges, two are instead stung 3 and get back to receiving state, again this device is firmly mentioned withdrawal.
The utility model structure is simple; easy to use; the above is only detailed description of the invention of the present utility model; should be understood that; to those skilled in the art; under the prerequisite not departing from the utility model principle, can also make some improvements and modifications, these improvements and modifications also should be considered as within protection domain of the present utility model.
