When rising electric wire, safety clearance must be left between workmen and electric wire, but the safety clearance of the form of construction work is difficult to obtain
Ensure, therefore great potential safety hazard is caused to workmen.
The cross-arm of electric pole includes straight line cross-arm, buck arm and double cross-arms, and the patent No. 201520555258.8 is disclosed
Phase livewire work lifter special in a kind of 35kV and following multiloop（Such as Fig. 1）, the suspended structure in the lifter can only fit
For double cross-arms, applicability is small.
Cheese 500 in lifter disclosed in above-mentioned patent is located at the lower section of mounting bracket 600, and mounting bracket is carried on a shoulder pole in cross-arm 400
On.When electric wire is lifted, the lower section of mounting bracket 600 is located at due to cheese 500, during liter is hung, cross-arm 400 will necessarily for electric wire
Interfere the rising of electric wire, therefore electric wire can only be always positioned at cross-arm lower section.So when electric wire hangs and rises to below cross-arm, in addition it is also necessary to
By an insulating bar, first the electric wire is chosen to insulating bar, cross-arm is then bypassed by the insulating bar and electric wire is placed into cross-arm
Upper surface on, the operating process is cumbersome, and electric wire easily slides, and potential safety hazard is big.
Therefore, it is necessory to be improved to solve the deficiency of prior art to prior art.
The content of the invention：
The utility model is to provide the suspension in a kind of lifting device to solve the problems, such as above-mentioned prior art
Mechanism.
The technical scheme that the utility model is used has：A kind of hitch in lifting device, including support frame, folder
Plate, trip bolt, support bar and action bars, clamping plate described in two are plugged on the both sides of support frame, and clamping plate and support frame respectively
Between be formed with clamping chamber, trip bolt is threaded on support frame, and the bottom of trip bolt is connected on clamping plate, support
Bar and action bars are articulated with the lower surface of support frame.
Further, the both sides of support frame as described above extend and form the first double wall vertically downward, the ending vertical of clamping plate to
Lower bending simultaneously forms the second double wall, and the clamping chamber is formed between the first double wall and the second double wall.
Further, it is equipped with cone tooth on the inwall of first double wall and the second double wall.
Further, the center of support frame as described above is provided with through hole.
Further, the support bar is two poles, and friction pulley is provided with the bottom of support bar.
Further, the support bar and action bars are equipped with two, and two support bars are located between two action bars.
Further, the action bars is telescopic rod.
The utility model has the advantages that：
The utility model simple structure, is easy to operation, and good stability, applicability is wide, uses safety.
Brief description of the drawings：
Fig. 1 is the suspended structure figure of lifting device in background technology.
Fig. 2 is the front view of the utility model hitch.
Fig. 3 is the left view of the utility model hitch.
Fig. 4 is the application structure figure of the utility model hitch.
Specific embodiment：
The utility model is further described below in conjunction with the accompanying drawings.
As shown in Figures 2 and 3, the hitch in a kind of lifting device of the utility model, including support frame 21, clamping plate
22nd, trip bolt 23, support bar 4 and action bars 5, two clamping plates 22 are plugged on the both sides of support frame 21 respectively, and clamping plate 22 with
Clamping chamber 20 is formed between support frame 21, trip bolt 23 is threaded on support frame 21, and trip bolt 23 bottom
It is connected on clamping plate 22, and clamping plate 22 is fixed on support frame 21.Support bar 4 and action bars 5 are articulated with support frame 21
On lower surface.
The both sides of support frame 21 extend and form the first double wall 210, the end of clamping plate 22 vertically downward in the utility model
Bending vertically downward simultaneously forms the second double wall 220, and the clamping chamber 20 is formed between the first double wall 210 and the second double wall 220.
To increase the frictional force on the utility model hitch and electric wire tower bar between cross-arm, in the He of the first double wall 210
Cone tooth is equipped with the inwall of the second double wall 220.
For during preventing the rise and fall of lifting rope 12, suspension hook 13 occurs the swing along the axis direction of take-up reel 11, in branch
The center of support 21 is provided with the through hole 218 for wearing lifting rope 12.The through hole 218 can be prevented effectively in the generation of suspension hook 13
State swing.
For ease of the electric wire tower bar suitable for different tube diameters, the support bar 4 in the utility model is two poles.For ease of branch
Strut 4 is preferably connected on electric wire tower bar, and friction pulley 41 is provided with the bottom of support bar 4.
Support bar 4 and action bars 5 are equipped with two, and two support bars 4 are located between two action bars 5.Two action bars 5 are easy to
Operation, two support bar 4 increases the stability of the utility model hitch.Action bars 5 is telescopic rod, it is adaptable to different height
Cross bar.
With reference to Fig. 4, workmen is risen to by aerial lift device with insulated arm and treats operation electric pole side, and workmen is by operation
Be suspended on the utility model hitch on the cross-arm of electric wire tower bar by bar 5（This implementation process is by taking straight line cross-arm as an example）, pass through
The size that adjustment clamps chamber 20 is used to be applied to various sizes of cross-arm, and the friction pulley 41 of the bottom of support bar 4 is resisted against electric wire tower
On bar, good stability.
When using the utility model hitch, take-up reel 11 is fixed on the top of support frame 21, suspension hook 13 is passed through
Through hole 218 simultaneously stretches in issuing for support frame 21.The top of the cross-arm of electric wire tower bar is located at due to take-up reel 11, take-up reel 11 is hanging
Rise during electric wire, if cross bar interference electric wire rises, only need to thoroughly do away with the edge body of rod by one and pull electric wire so that electric wire deviates
The interference position of cross bar, then take-up reel 11 continue to hang liter electric wire and electric wire hung the top for rising to cross bar.If cross bar is not interfered
Electric wire rises, then take-up reel 11 directly can be lifted to cross-arm top electric wire.Electric wire is chosen from hanging by the above-mentioned insulation body of rod afterwards
Hook 13, you can realize placing electric wire on cross-arm.
Electric wire tower bar cross-arm be buck arm or double cross-arms when, only need to by the utility model lifting device place to
On one side of buck arm or double cross-arms, and cause that the friction pulley 41 of lifting device is resisted against on electric wire tower bar, you can real
The lifting of existing electric wire.
The above is only preferred embodiment of the present utility model, it is noted that for the common skill of the art
For art personnel, some improvement can also be made on the premise of the utility model principle is not departed from, these improvement also should be regarded as
Protection domain of the present utility model.
