Abstract

The utility model discloses a portable type revolving chair for working on pole line mainly used for reducing electric power or the labor intensity in operating on the communication line. The utility model whose seat pad is arranged on a supporting rod connected with a tight loop by a hinge is fixed to the operation pole section by using the tight loop. The hinge axial line and the axial line of the supporting rod are coplanar and parallel, and the seat pad can rotate around the hinge point and bear gravity to meet the requirements of operation. The tight loop and the supporting rod are made of steel tubes, and which are the main parts of a portable type revolving chair for working on pole line. The utility model has the advantages of convenience for carrying, light weight, high strength, high safety.

Description

Portable type revolving chair for working on pole line

Operation swivel chair on the portable bar that the utility model relates to is the aid of a kind of electric power or communication line operation, is mainly used in to improve operations labor intensity on the long-time bar of operating personnel.

In the prior art, during line maintenance worker novel ladder, only depend on two climbers to support human weight, the operation of long period such as charged for replacement bar section and the intersegmental weld job of bar, labour intensity is all bigger, even might be because of the accident of meeting accident of being short of physical strength; Though can recover muscle power with three soles, effect is undesirable, nor just operation.

Task of the present utility model is to overcome existing above-mentioned deficiency in the prior art, and provides a kind of mounting or dismounting convenient, rotates operation swivel chair on flexible, the safe and reliable bar, to reach the purpose that alleviates operating personnel's labour intensity.

The utility model proposes of task is finished by following technical proposal, and the utility model is fixed a fixed joint pin or the cover with bar section parallel axes coplane of the outer rim of a tight loop on operation bar section.Get one section steel pipe as cramp bar, one seat cushion is installed on this cramp bar, and at fixed hinge sleeve of boom end or pin, after joint pin inserts hinge sleeve, seat cushion and cramp bar just can be done the swing of certain angle around pin joint, the operator can be sitting in and carry out operation in the certain limit on the seat cushion, alleviates labor intensity of operating personnel.

The utility model will be described in detail by embodiment.

Fig. 1 is an operation swivel chair schematic diagram on the utility model climbers formula fixed lever.

Fig. 2 is that the K of Fig. 1 is to view.

Fig. 3 is that the utility model is embraced operation swivel chair schematic diagram on the circle formula fixed lever.

Fig. 4 is that the R of Fig. 3 is to view.

Swivel chair on the climbers formula fixed lever as depicted in figs. 1 and 2 mainly is made up of the cramp bar 3 of climbers formula tight loop 1 and seated pad 2.Adopt hinge 4 to be connected the axis of this hinge 4 and rod axis coplane and parallel between tight loop 1 and the cramp bar 3.During operation, the maintainer carries upper boom with tight loop 1 and cramp bar 3, and for the effect that reaches in light weight, intensity is high, tight loop 1 and cramp bar 3 all adopt steel pipe to make.Tight loop 1 is installed on the bar, because be provided with the brake pad 5 that rubber or soft engineering plastics are made at openend, has increased the frictional force of contact surface, and tight loop 1 itself has rigidity preferably again, thereby as climbers, can support human weight reliably.But in the operating process, tight loop 1 needs to move the position sometimes, comes off in order to prevent it, at the two ends of tight loop 1 opening, two pins is installed or is bored two holes, and with an elastic 6 or spring 6 ' be connected with two pins or two holes, make it to form a closed circular.In order to improve the security reliability of swivel chair on the bar, cramp bar 3 should have certain restriction around the corner α that pin joint rotates, and also the rotary spacing pin can be set in case of necessity.

Swivel chair on armful circle formula fixed lever as shown in Figure 3 and Figure 4, be consolidated with two rocker bar bearings 8 on the outer rim of tight loop 7, the cramp bar 3 of the pad 2 of usheing to seat, its rod end is consolidated with a joint pin 9, between cramp bar 3 and the tight loop 7 for hinge is connected, so cramp bar 3 can be done the rotation of big corner β around pin joint.In order to adapt to the bar section operation in different bars footpath, tight loop 7 is provided with the girth governor motion 10 of joint form; Insert different connecting holes by pin 11, the girth of tight loop 7 is changed, treat that adjusting finishes, tighten milled screw 12 again, make tight loop 7 fixing.In order to increase the frictional force between tight loop 7 and the bar, be connected with fricting strip 13 at the inner edge of tight loop 7, this fricting strip 13 is generally also made with rubber or soft engineering plastics.

The utility model compared with prior art has following advantages: the utility model has alleviated on electric power or the communication line bar especially long period Job Operations personnel's labour intensity of operation effectively, simple in structure, carry and install all more convenient, and safe and reliable, have good social benefit.
