Abstract
The utility model discloses a special crank for a handcart of a power system, which is provided with a crank body and a square fixed base, wherein a ratchet wheel and detent mechanism is arranged in one end of a rocker of the crank body; a ratchet wheel is fixedly connected with the rocker of the crank; the square fixed base is fixedly connected with a detent shaft and is vertical to the rocker of the crank; a positioning steel ball is arranged on the fixed base; an internal angle sleeve is sheathed on the fixed base; and a pit which is matched with the positioning steel ball is arranged in the internal angle sleeve. By means of the special crank for the handcart of the power system, the operations of different models of handcart switches and knife switches of various substations are completely satisfied.
Description
Technical field:
The utility model relates to a kind of electric power system handcart special-purpose cranking bar.
Background technology:
All the time, in each transformer station's grid switching operation because the model of wheelbarrow switch is varied, situ configuration the crank of multiple model, often need to carry the operating rocker handle of multiple model during the power transformation operation personnel operation, very easily occur leaking situations such as band or wrong band, have a strong impact on operating efficiency; Simultaneously traditional " Z-shaped " crank is because firmly unbalanced, and no anticreep measure often occurs on " Z-shaped " crank and takes off the situation of hurting sb.'s feelings, and directly influences operating personnel's personal safety.
Summary of the invention:
For overcoming the defective of prior art, the purpose of this utility model is to provide a kind of electric power system handcart special-purpose cranking bar, can adapt to the operation of various model handcarts and plug-in strip according to transformer station's execute-in-place needs, and is easy to carry, flexible operation safety.
The utility model technical solution problem adopts following technical scheme:
Electric power system handcart special-purpose cranking bar is provided with the crank body, in rocking bar one end of described crank body ratchet and pawl arrangement is set, and ratchet and crank rocking bar connect firmly; Connect firmly with pawl axis and the square firm banking vertical with the crank rocking bar is set, and described firm banking is provided with positioning ball, and the interior angle jacket casing is connected on the described firm banking, and is provided with the pit that mates with positioning ball in the interior angle sleeve.
Be socketed with anti-skid sleeve on the hand body of rod of described crank body.
Compared with the prior art, the beneficial effects of the utility model are embodied in:
1, this electric power system handcart special-purpose cranking bar, greatly the handled easily personnel carry.
2, this electric power system handcart special-purpose cranking bar satisfies the operation of the wheelbarrow switch and the plug-in strip of each transformer station's different model fully.
3, " Z-shaped " change " arc ", and the design of hand-held anti-skid sleeve, make more convenient operation, more laborsaving, and can not take off problem, guaranteed operating personnel's personal safety.
4, design has positioning ball on the firm banking of crank front end, guarantees to be connected firmly between crank and the sleeve.
5, ratchet can be regulated rotation direction by ratchet, and crank need not 360 ° of rotations and can finish the work like this.
Description of drawings:
Fig. 1 is a structural representation of the present utility model; Fig. 2 is the left view of Fig. 1; Fig. 3 is the schematic diagram of interior angle sleeve; Fig. 4 (a, b, c, d) is the left view of all kinds of interior angle sleeves.
Number in the figure: 1 crank body, 2 firm bankings, 3 positioning balls, 4 interior angle sleeves, 5 pits, the 6 hand bodies of rod, 7 anti-skid sleeves.
Below pass through embodiment, and the utility model is described in further detail in conjunction with the accompanying drawings.
Embodiment:
Embodiment: in conjunction with Fig. 1-4, the electric power system handcart special-purpose cranking bar of present embodiment is provided with crank body 1, in rocking bar one end of described crank body 1 ratchet and pawl arrangement is set, and ratchet and crank rocking bar connect firmly; Connect firmly with pawl axis and the square firm banking 2 vertical with the crank rocking bar is set, and described firm banking 2 is provided with positioning ball 3, and interior angle sleeve 4 is socketed on the described firm banking 2, and is provided with the pit 5 that mates with positioning ball 3 in the interior angle sleeve.
Be socketed with anti-skid sleeve 7 on the hand body of rod 6 of described crank body.
In specifically being provided with, the crank body is selected the high-quality stainless steel material for use.Movable interior angle sleeve, the sleeve that can change corresponding model at the handcart or the plug-in strip of different model, shown in Fig. 4 (a, b, c, d), a secondary crank is furnished with the interior angle sleeve of various models, satisfies the operation of on-the-spot various handcart or plug-in strip.
Crank " arc " design, hand body of rod stress equalization in operation, easy to use, handgrip part (being the hand body of rod) installs the plastics anti-skid sleeve additional, reduces the friction between hand and the crank, prevents from handle to occur taking off in the operation.
