Description

Pole-climbing chair

The utility model relates to a kind of instrument of climbing cement pole, says it is a kind of Pole-climbing chair definitely.

Cement pole is used to install electric wiring or telephone wire.At present, climbing instrument commonly used is a climb plank, this plate is connected with rope, also is provided with hook on the rope, during climbing, hand-held rope surrounds cement pole, with hook hook jail rope, the people steps on onboard, again with another climb plank as described above method hang on the bar, constantly be used alternatingly a secondary climb plank, the operator just can climb up masthead and carry out work.This climb plank is simple in structure, but troublesome poeration is very hard, and the speed of ascending a height is slow, danger is also big.

The purpose of this utility model is to provide a kind of and saves labour, quick, easy to operate and safe Pole-climbing chair.

For achieving the above object, Pole-climbing chair of the present utility model comprises an elevating lever, fixedly connected with handle in its upper end, the lower end is flexibly connected by pin and following snap ring ring seat, the lower end of pedaling bar is also flexibly connected by pin and ring seat, two are provided with foot-operated depression bar middle part and are movably connected on the bolt of pedaling the bar upper end, and this bolt also passes the slotted eye of elevating lever; Depression bar flexibly connects by strut and the top tube that is located on the elevating lever again, is with the snap ring cross-arm on the elevating lever of tube top, top, also is provided with seat on the cross-arm; Upper and lower snap ring is formed by connecting by sleeve pipe and CONTEN STEEL OVAL NECK TRACK BOLTS by two semicircular ring.

Be provided with spring on the elevating lever between said handle and the cross-arm, this spring also is provided with the spring strut that is shorter than spring outward.

In the ring of said upper and lower snap ring, be provided with latch.

Because technique scheme has adopted two snap rings up and down, and following snap ring ring seat and elevating lever flexibly connect, last snap ring and seat are installed on the cross-arm, cross-arm is enclosed within the elevating lever, adopted the structure of pushing up tube and depression bar, strut, pedaling bar again, therefore, just can reach the purpose of stepping on bar as long as be used alternatingly two snap rings.When climbing bar, pedal depression bar and standing, following snap ring tilts to be held on the cement pole, the top tube is seated on the seat when lifting cross-arm to worker's crotch portion, and last snap ring tilts to be held on the cement pole portable handle, following snap ring rises, and just climbs up masthead so repeatedly very soon, the work of also can standing of can sitting down.During lower beam, the jog handle lands snap ring automatically, and pin is stepped on strut makes top tube toward rising, and gently shakes handle, last snap ring together with the seat landing to a top, top, alternate operation, Pole-climbing chair just can drop to ground.This Pole-climbing chair saves labour, quick, simple to operate and safety and comfort.

Below in conjunction with the drawings and specific embodiments the utility model is described in further detail.

Fig. 1 is the structural representation of the utility model Pole-climbing chair.

As seen from Figure 1, Pole-climbing chair of the present utility model comprises an elevating lever 1, fixedlys connected with handle 2 in its top, and the ring seat of lower end and snap ring 3 flexibly connects by pin, and the lower end of pedaling bar 4 also flexibly connects by pin with ring seat.Foot-operated 5 are located at an end of depression bar 6, also are provided with grapple 7 on foot-operated 5 so that use during landing.The middle part of two depression bars 6 is movably connected on the bolt 8 of pedaling bar 4 upper ends, bolt 8 passes the slotted eye 9 on the elevating lever 1 again, make elevating lever 1 and pedal bar 4 and be connected, depression bar 6 flexibly connects by strut 10 and the top tube 11 that is located on the elevating lever 1 again, and each connecting portion can be connected firmly with pin or bolt.Last snap ring 12 is fixedly mounted on an end of cross-arm 13, and seat 14 is fixedly mounted on the other end of cross-arm 13, and seat 14 has a circle backrest, to increase security and comfortableness.Have hole 15 on the cross-arm 13, and be enclosed within on the elevating lever 1, and place the top of top tube 11 by this hole 15.Last snap ring 12 and following snap ring 3 are formed by two semicircular ring, fixedly connected with sleeve pipe 16 in the two ends of a semicircular ring, sleeve pipe 16 is passed at the two ends of another semicircular ring, and connect into a domain by CONTEN STEEL OVAL NECK TRACK BOLTS 17, be provided with anti-skidding latch 18 in the ring, perhaps ring is gone up the parcel rubber layer to increase frictional force.For snap ring is risen automatically, on the elevating lever 1 between cross-arm 13 and the handle 2, also be provided with spring 19, also be provided with the spring strut 20 that is shorter than spring outside the spring 19, spring strut 20 is provided with bayonet lock 21, and cross-arm 13 is provided with pin hole 22, and the bayonet lock locating slot is arranged in the hole.

When climbing bar, unclamp CONTEN STEEL OVAL NECK TRACK BOLTS 17 earlier, upper and lower two snap rings are enclosed within on the cement pole, the screw 17 of screwing on again, and keep snap ring and cement pole that certain interval is arranged.The worker is sitting on the seat 14, ride 5 with pedal, both hands buttress cement pole and stand, at this moment, pedaling bar 4 is subjected to human body gravity to make down snap ring 3 become certain angle of inclination with cement pole, latch 18 tightly is stuck on the cement pole, and simultaneously, top tube 11 makes on the cross-arm 13 under the promotion of depression bar 6 and strut 10 and moves, spring 19 is compressed, just be seated on the seat 14 when cross-arm 13 moves to worker's crotch portion, body weight makes snap ring 12 become certain angle of inclination with cement pole, and latch 18 is stuck on the cement pole tightly.Compressed spring 19 acts on the handle 2, promotes elevating lever 1 and makes down snap ring 3 become 90 to spend with cement pole, and rise not having under the frictional resistance.So repeatable operation just can very fast arrival working position.During lower beam, with spring 19 compressions, in the pin hole 22 that the bayonet lock 21 of spring strut 20 inserts on the cross-arm 13, rotation spring strut 20 is held in the bayonet lock locating slot it, light handle 2 makes down snap ring 3 become 90 degree with cement pole, following snap ring 3 and elevating lever 1 be landing automatically just, handle 2 hangs over the top of spring strut 20, and pin steps on foot-operated 5 and grapple 7 is hooked on the strut 10, or directly steps down on the strut 10, top tube 11 can be toward rising, body weight falls within down on the snap ring 3, gently shakes handle 2, and last snap ring 12 and seat 14 drop to the top of top tube 11 automatically, shift center of gravity gravity by turns, Pole-climbing chair just can drop to ground.
