Abstract

The utility model provides a pole erecting device which can be used when an electrician erects an electric pole. The pole erecting device is composed of a pedestal, a lifting rack, a mechanical hand, and a lifting screw. The lifting screw is used for supplying power to lifting the lifting rack with multiple layers, and then the end of the electric pole can be lifted to a certain height. The electric pole can be adjusted in proper position through the cooperation of ropes, and the work of erecting the pole can be completed. The pole erecting device has the advantages of simple structure, safe operation, convenient maintenance, labor saving, and high efficiency.

Description

Fastener

The utility model relates to a kind of vertical rod device, and a kind of specifically electrician erects the used vertical rod apparatus of electric pole.

Employed apparatus when the electrician erects electric pole at present, one is to use crane, and the 2nd, tie " people " font to fasten electric pole and carefully hold with two stocks, firmly with the electric pole pull-up, a kind of poling method personnel selection in back is many with manpower, and labour intensity is big, and safety factor is little.

The purpose of this utility model provides a kind of laborsaving standing device, and it can help safety of workers, finish the vertical rod task effortlessly.

The purpose of this utility model is achieved in that this standing device is made up of base, undercarriage, manipulator and jack.Base 1 is a strip steel part, lower floor's one end of the undercarriage 7 of layering and an end hinge of base 1, the other end 8 is limited in the slideway 5 of base by pivot pin 9, manipulator is by the top layer central authorities of pivot pin 9 hinges at undercarriage 7, the bottom of jack 10 is connected on the overhanging pin frame 6 of base 1, and the central authorities of lower floor of the termination of its push rod 11 and undercarriage 7 are by pivot pin 9 hinges.

Fig. 1 is the whole static front view of laborsaving standing device.

Fig. 2 is this standing device bottom working state schematic representation.

Fig. 3 is the sectional view along Figure 1A-A line.

Fig. 4 is the sectional view along Figure 1B-B line.

Fig. 5 is the sectional view along Fig. 1 C-C line.

Below in conjunction with these accompanying drawings concrete structure of the present utility model is described in detail.

As shown in Figure 1, the base 1 of this standing device is a strip steel part, and two isometric overhanging pin 2 are arranged at its two ends, overhanging pin 2 the outer end stabilize screw 3 is arranged, the inner has one to limit screw 4, in addition, on an end top of base 1 a shaped as frame slideway 5 is arranged.

Manipulator is made up of Y type bracing frame 15, arc holding claw 16, slide block 14 and connecting rod 13, two identical shaped arc holding claws 16 are by the two ends of pivot pin 17 hinges at Y type bracing frame 15, the slide block 14 that is supported by two isometric connecting rods 13 is enclosed within on the bar of Y type bracing frame 15, slide block 14 is parallel with base 1, and it is keeping Y type bracing frame 15 vertical with base 1.

Shown in Fig. 2,3, undercarriage 7 is layerings, every layer of girder steel that four identical shapes are arranged, these four girder steels are divided into two pairs again, whenever align replicate and close, with the corresponding hinge of girder steel of another layer, the spacing that 10～30cm is arranged between two pairs, the central authorities of every layer of girder steel are by pivot pin 9 hinges, an end hinge of an end of undercarriage lower floor and base 1, and the other end is limited in the slideway 5.

Fig. 1,4 illustrates the connection status of undercarriage top layer and manipulator, and the lower end hinge of the Y type bracing frame 15 of manipulator is in the top layer central authorities of undercarriage 7, and two connecting rods 13 are distinguished two terminations of hinges at the undercarriage top layer.

The slide block 14 that Fig. 5 illustrates manipulator is steel parts that are enclosed within on Y type bracing frame 15 bars, its two ends and two connecting rod 13 usefulness pivot pins 17 hinges, and by their its levels of support maintenance, slide block 14 is keeping the plumbness of bracing frame.

During vertical rod, at first with laborsaving standing device location, promptly pull out overhanging pin 2, adjust screw rod 3, again the thin end of electric pole is lifted on the holding claw 16 that is placed on manipulator, because the weight of electric pole self, holding claw is inwardly detained, tightly embrace electric pole, at this moment operate jack handle 12, push rod 11 is awarded power on the pivot pin 9 of central authorities of undercarriage lower floor, promote undercarriage to rising, undercarriage one end 8 is supported on slideway 5 inter-syncs by pivot pin 9 and slides inwards, every pair of steel disc intersection of every layer of girder steel of undercarriage is * shape, as shown in Figure 2, overhanging gradually along with jack bar 11, the contention that girder steel intersects is cumulative big, and undercarriage just rises gradually, because undercarriage is a multilayer, the multilayer girder steel * the shape stack, just electric pole one end can be elected enough height, operate the rope that ties up to the electric pole termination in advance this moment again, sets upright electric pole, reclaim undercarriage simultaneously, whole vertical rod work has just been finished.

The utility model is simple in structure, and handling safety is easy to maintenance, and is laborsaving, and is efficient, particularly suitable to the location that crane can't put in place.
