Abstract
The utility model belongs to the power system equipment maintenance and repair field and relates to a 10kV earthing drill rod pulling device. The 10kV earthing drill rod pulling device is composed of a transmission device (1), a fixing device (2) and a supporting device (3), wherein the transmission device is of a lead screw structure. According to the 10kV earthing drill rod pulling device of the utility model, by means of lead screw principles, an arm of force is rotated so that the insertion and pulling out of an earthing drill rod can be driven, and therefore, the 10kV earthing drill rod pulling device is advantageous in simple operation, and time-saving and labor-saving properties, and can greatly reduce the labor intensity of an operator and improve work efficiency; and a stabilizing pad is additionally arranged at the bottom of the supporting device, and therefore, equipment can be stabilized, and at the same time, a supporting frame can be prevented from being inserted into the ground because that the supporting frame is stressed. The 10kV earthing drill rod pulling device of the utility model is further advantageous in convenient installation and low cost, and is suitable for being popularized and applied to a whole power system and related fields.
Description
Technical field
the utility model relates to power system device maintenance field, relates in particular to a kind of 10kV ground connection hammer drill driver-extractor.
Background technology
when traditional earth rod is constructed in the winter time or runs into harder soil, often because self insufficient strength of earth rod, causing earth rod pounding in underground process, is not to pound motionlessly, causes exactly earth rod bending, damage.In installation provision, explicitly call for earth electrode to be forbidden to be less than 0.6m in the subsurface degree of depth, even if pound reluctantly into underground, reach safety requirement, remove in earth connection process in the end of job, the phenomenon that earth rod also often has the difficulty of taking out and cannot take out, incurs loss through delay electric power feeding time.
The portable earth connection of traditional 10kV and 0.4kV, ground connection hammer drill buried depth require be 0.6 meter, generally with hammer pound into, when dismounting, manually pull out.Soft and the non-ice period in soil property, remove than being easier to, and in the frozen soil layer in hard soil property, aggregate structure and winter, manually be just difficult to pull out with hand, after beaing with hammer left and right, be also not easy to pull out, scene abandons ground connection hammer drill phenomenon and happens occasionally, and What is more, for the convenient ground connection hammer drill of removing, adopt the way violating the regulations that reduces ground connection hammer drill buried depth.Because ground connection hammer drill length is generally in 800mm left and right, " T " structure, utilizes lever principle, while adopting two crowbars to sled, and the bad grasp of two lateral balances, the road clearance is little, causes stroke inadequate, and effect is also undesirable.Adopt spiral ground connection hammer drill, while running into aggregate structure soil property, the degree of depth is entered not go, and adopts common hammer drill, as long as overstriking just can be pounded into ground, key is to remove difficulty.
Utility model content
In order to solve above-mentioned deficiency of the prior art, the utility model provides a kind of 10kV ground connection hammer drill driver-extractor, and object is to make a kind of instrument that facilitates the plug of ground connection hammer drill, the plug of ground connection hammer drill is conveniently reached save time, labour-saving object.
The utility model is achieved through the following technical solutions:
10kV ground connection hammer drill driver-extractor, is made up of transmission device, fixture, bracing or strutting arrangement, and described transmission device is screw structure.
Described bracing or strutting arrangement top is fixedly connected with the circular metal plate of centre-drilling hole, metal sleeve is vertically fixed through centre bore and circular metal plate, leading screw vertically penetrates in metal sleeve, leading screw top disposes transmission nut, on transmission nut, weld handle, leading screw lower end is fixedly connected with fixture, and fixture is connected and fixed ground connection hammer drill.
Described fixture structure is: hold-down nut is fixed on turn-screw lower end, two iron plates of nut below transverse weld, and the boring of iron plate vertical direction penetrates two screws, and two link upper ends are respectively through two screws active link iron plate.
Described bracing or strutting arrangement is tripod structure.
Described support means bottom portion adds stable pad.
A little of the present utility model and beneficial effect is: the utility model is by leading screw principle, rotary arm drives the plug of ground connection hammer drill, simple to operate, time saving and energy saving, greatly alleviate operating personnel's labour intensity, increased operating efficiency, support means bottom portion installs stable pad additional, and stabilizing equipment prevents that bracing frame is because of stressed insertion ground simultaneously.The utility model is easy for installation and cheap, is applicable to whole electric power system and association area and applies.
Brief description of the drawings
Fig. 1 is the utility model structural representation;
In figure: 1, transmission device, 2, fixture, 3, fixture, 4, leading screw, 5, transmission nut, 6, circular metal plate, 7, metal sleeve, 8, handle, 9, hold-down nut, 10, metallic plate, 11, link, 12, stable pad, 13, ground connection hammer drill.
Embodiment
embodiment:
As shown in Figure 1: structure is made up of three parts:
1, bracing or strutting arrangement 1: adopt the reinforcing bar of M18 to do triangle supporting leg, lower end adds stable pad 12, prevents from inserting ground.
2, fixture 2: hold-down nut 9 is welded on turn-screw 4 lower ends, two iron plates 10 of transverse weld below nut, iron plate 10 vertical direction borings penetrate two screws, for two links 11 are fixed, direction is adjustable, and leading screw 4 transmission nut 5 above welds a handle 8, is rotated
3, running part 3: with 4 one of the leading screws of diameter 25mm, join two nuts, upper end is welded on the round iron plate 6 that 4mm is thick, and in the middle of iron plate,, after boring, the metallic sheath 7 that internal diameter is slightly larger than to 25mm is welded in hole, and leading screw 4 is through the metallic sheath in iron plate.
When use, driver-extractor is placed on to ground connection hammer drill 13 tops, square nut on adjusting screw, allows the link of below tangle ground connection hammer drill, with the nut of hand rotational lead screw top, leading screw is moved upward, supporting leg is subject to reaction force and tightly presses on the ground, and ground connection hammer drill, under the pulling of leading screw, starts to move up, thereby built on stilts, extracts hammer drill.
Present case is applied in Dandong, Dandong, implemented to use by Chang'an power supply station of power supply branch of Donggang City, after long-time application, income effect than anticipation in good, ground connection hammer drill is without vertical ground, with certain angle, or run into stone etc. and produced bending, all equally can pull out, and firmly little, can rotate once a personal hand, winter freezing after, carried out again frozen soil experiment, effect is the same, and leading screw also need not be oversize, 800mm left and right is just passable, whole equipment 2.5KG, convenient in carrying, 500 yuan of whole costs.
