Abstract
The utility model relates to an overhead ground wire lifting mechanism which is safe and convenient to use. The overhead ground wire lifting mechanism comprises a support, wherein one end of the support is fixedly connected with a lead screw side suspension hanging piece, and the other end of the support is fixedly connected with a hook side suspension hanging piece; the middle part of the support is fixedly connected with a base, and the base is provided with a downward opening; a lead screw is installed below the lead screw side suspension hanging piece in a relatively rotary mode, the lower part of the lead screw is connected with a sleeve through screw threads, and a lifting hook is installed at the lower end of the sleeve; a wire spooler is connected with the lead screw through screw threads and is positioned above the sleeve, and the handle is installed on the wire spooler; and a hook is installed below the hook side suspension hanging piece in a relatively rotary mode. By adopting the overhead ground wire lifting mechanism, ground wires can be safely and conveniently lifted, the number of operators on a tower can be reduced, and the labor intensity of the operators is lightened.
Description
Technical field
The utility model relates to a kind of electric operating instrument, relates in particular to a kind of overhead ground wire lifter.
Background technology
Mostly transmission line is big span design in recent years; The immediate problem that brings thus is that vertical load increases; When the construction of carrying out overhead ground wire, upkeep operation; Need overhead ground wire put into earlier it to be risen by coaster behind coaster, the end-of-job again and winch to the ground wire suspension clamp, the operating personnel accomplishes on the whole process need 2-3 name tower.Because overhead ground wire holder part size is less, operating personnel's scope of activities is limited on the tower, is inconvenient to operate, and the increase of vertical load also makes the ground wire lifting operation have very big potential safety hazard in addition.
Summary of the invention
The purpose of the utility model provides a kind of safe in utilization, overhead ground wire lifter easily.
For realizing above-mentioned purpose, the technical scheme that the utility model adopts is:
A kind of overhead ground wire lifter comprises support, it is characterized in that: a support wherein end is fixedly connected with the leading screw side mounting and hangs sheet, and the support other end is fixedly connected with the hook side mounting and hangs sheet, and mid-stent is fixedly connected with base, and base has downward opening; The leading screw side mounting is hung and is rotatably installed with leading screw relatively below the sheet, and the leading screw lower thread is connected with sleeve, and the sleeve lower end is equipped with hoist hook, and the spooler that has been threaded on the leading screw, spooler are positioned at the sleeve top, and handle is installed on the spooler; The hook side mounting is hung and is rotatably installed with hook relatively below the sheet.Said support is a triangle.
Can make ground wire slinging work safety, the convenient completion by the utility model, can reduce operating personnel's on the tower number and alleviate operating personnel's labour intensity.
Description of drawings
Fig. 1 is the structural representation of the utility model.
In the accompanying drawing:
1, support; 2, sheet is hung in the leading screw side mounting; 3, leading screw; 4, spooler; 5, sleeve; 6, hoist hook; 7, handle; 8, base; 9, hook; 10, sheet is hung in the hook side mounting.
Embodiment
Below in conjunction with accompanying drawing and specific embodiment the utility model is further described:
A kind of overhead ground wire lifter, as shown in Figure 1, comprise support 1; Support 1 a wherein end is fixedly connected with the leading screw side mounting and hangs sheet 2; Support 1 other end is fixedly connected with the hook side mounting and hangs sheet 10, and support 1 middle part is fixedly connected with base 8, and base 8 has downward opening; The leading screw side mounting is hung and is rotatably installed with leading screw 3 relatively below the sheet 2, and leading screw 3 lower thread are connected with sleeve 5, and sleeve 5 lower ends are equipped with hoist hook 6, and the spooler 4 that has been threaded on the leading screw 3, spooler 4 are positioned at sleeve 5 tops, and handle 7 is installed on the spooler 4; The hook side mounting is hung and is rotatably installed with hook 9 below the sheet 10 relatively.In the present embodiment, said support 1 is a triangle.
Embodiment recited above describes the preferred implementation of the utility model; Be not that design and scope to the utility model limits; Under the prerequisite that does not break away from the utility model design concept, common engineers and technicians make the technical scheme of the utility model in this area various modification and improvement all should fall into the protection range of the utility model; The technology contents that the utility model is asked for protection all is documented in claims.
The utility model has utilized lever principle; Leg-of-mutton support plays leverage; Support one end is provided with through suspension and hangs the leading screw that sheet is connected with support; The support other end is to hang the hook that sheet is connected with support through suspension, is about bracket bottom edge lengths 1/3 place with the hook distance and is provided with the base that is connected with support, plays the effect of lever principle central bearing point.
The utility model can carry out using when overhead ground wire promotes operation on transmission line, can realize easily operation on the single shaft tower, has changed the operational method that traditional simple dependence operating personnel shoulder strength promotes ground wire.Personnel's operation had been both inconvenient on two towers, also had potential safety hazard, and the utility model has thoroughly solved this difficult problem, has successfully realized single easy manipulation, greatly the assurance of degree the fail safe of operation.
In the utility model, triangular supports and hook side mounting are hung sheet, base, leading screw side mounting and are hung being connected of sheet and adopt welding manner.
The concrete operation method that uses the utility model to promote ground wire is: base is fixed on overhead ground wire cross-arm top; Hook overhead ground wire through hook; Rotary handle descends hoist hook, hooks overhead ground wire and is positioned at a cross-arm opposite side side opposite with hook, and base becomes the fulcrum of lever; Thereby reverse rotation this moment handle rises hoist hook rises overhead ground wire, and overhead ground wire is mentioned.After related work is accomplished, overhead ground wire is put back in the overhead ground wire suspension clamp got final product again.
The utility model can be realized on the single tower easily operation, changed the simple in the past operational method that relies on the men hoisting overhead ground wire, has avoided the potential safety hazard that the common operation of personnel exists on two towers simultaneously.And simple in structure, easy for operation, reduced labour intensity, greatly improved the efficiency and the coefficient of safety of electric power line pole tower operation.
