Abstract

The utility model discloses a portable working table on pole, which is mainly used for alleviating the labor intensity of operation on pole in electric power or communication lines. The portable working table is composed of a platform, a strut angle, a clamping head, a hinge and a screw bolt, wherein, the platform is supported by the strut angle and is in 90DEG with a telegraph pole; the strut angle is supported and clamped on the telegraph pole. The other end of the platform is mutually connected with the convex position of the clamping head; one end of the clamping head is mutually connected with the hinge through the screw bolt; the other end is mutually connected with a fastening screw bolt; the hinge and the fastening screw bolt are clamped by a lock clamp. The whole device and the telegraph pole are combined into one body. Persons standing on the platform to operate has the characteristics of labor saving, rapidity, etc.

Description

Portable working table on pole

The utility model relates to a kind of portable operation post that the electric pole work high above the ground is used that is used for, and belongs to the aid of electric power or communication line operation.

For these years, during line maintenance worker novel ladder, only depend on two climbers to support human weight.During operation, fasten safety belt after, need pin to step down on the climbers sideling health and work, health is the imbalance accident that just can meet accident slightly.Occur lift for this reason, needed both feet pedal ladder during operation, operation on bar, because ladder and electric pole still have certain gradient, so the person is still worked under unbalanced state, and the people need lie prone on ladder, not only required great effort but also inconvenience.Also have a kind of nonvolatil operation post, fixed installation one operation post props up during use on the bar, and just the spare time is putting, and this operation post investment is big, heavy impracticable, is not subjected to the welcome of operating worker.In addition, Chinese patent CN87214086U discloses a kind of " operation chair on the portable bar ", its scheme is to fix a joint pin or a cover with bar section parallel axes coplane on operation bar section, with a steel pipe is support bar, peace one seat cushion on the support bar, and the operator can be sitting in the operation of carrying out certain limit on the seat cushion, this operation chair can reduce labor intensity, but its project organization is unreasonable, especially can not satisfy the needs of standing at work, and using has limitation.

The purpose of this utility model is to overcome above-mentioned weak point of the prior art, and a kind of reasonable in design, practicality, easy accessibility, safe and reliable are provided, operation post on the portable bar easy for operation.

The purpose of this utility model is achieved in that it comprises electric pole, bolt.Fixedly chain, dop, hinge, pintle hook lock constitute by platform, support angle, support angle for it.One end of platform is fixedlyed connected with support angle by bolt, and the other end is fixedlyed connected with dop, the bottom of platform by support angle fixedly chain be connected with support angle, support angle props up on electric pole.One end of hinge is connected with dop, and the other end of dop is fixed by fastening bolt, and fastening bolt and hinge are fixed by pintle hook lock, and dop is fastened on the electric pole.

The purpose of this utility model can also reach by following measure: its platform and electric pole are 90 ° of placements.

The utlity model has following advantage compared to existing technology:

1, reasonable in design owing to designed job platform, work laborsaving, make things convenient for, on bar, avoided sideling body to work and alleviated labour intensity greatly.

2, in light weight, easy to carry, the user of service can carry or free-hand carrying with bicycle.

3, cost is low, is about 1/3 of aluminium ladder, can reduce production costs greatly.

4, long service life is longer more than 2 times than ladder.

5, accommodation is extensive, be particularly useful for electric power, telecommunications industry cement pole, wooden stick, institute puts no matter thick bar, the thin arbitrary height either direction of bar can both be followed one's inclinations.If cooperate the supporting use of Minnesota Mining and Manufacturing Company's novel cable tool for connecting handy especially.

The drawing explanation of accompanying drawing:

Fig. 1 is the utility model overall structure schematic diagram.

Fig. 2 is the utility model dop structural representation.

Embodiment describes the utility model in detail below in conjunction with (accompanying drawing).

Among the figure, electric pole (1), dop (2), hinge (3), pintle hook lock (4), fastening bolt (5), platform (6), support angle be chain (7), support angle (8) fixedly.

The utility model is a critical piece with platform (6), dop (2), hinge (3), support angle (8), is equipped with bolt.Dop (2) be "

" shape, be the link of platform (6) and electric pole (1), adopt steel plate, its end is connected with bolt with hinge (3), and its boss is connected by bolted with platform (6), and the other end and fastening bolt (5) are fastenedly connected.Fastening bolt (5), hinge (3) block by pintle hook lock (4), and the effect of hinge (3) is that dop (2) is fixed on the electric pole (1).The effect of fastening bolt (5) is that dop (2), hinge (3) together are fastened on the electric pole (1).Platform (6) is a fastening durable flat board, bear pressure greater than 200kg, be 90 ° of placements with electric pole (1), direction, position can be adjusted arbitrarily, and its two ends are equipped with bolt hole, and the bottom is supported with support angle (8), one end of support angle (8) also is provided with bolt hole, bolt therefrom passes, and platform (2) and support angle (8) is fastening, the other end of platform (6) and dop (2) boss bolted.The other end of support angle (8) props up and is stuck on the electric pole (1), support angle (8) adopts steel pipe, and its 1/3 place is provided with a crossbeam, and the middle part of crossbeam is fixed with a collar, support angle fixedly chain (7) passes from ring, and the spike fixedly bottom usefulness pin of the top of chain (7) and platform (2) is fastening.For making the utility model sturdy and durable, support angle fixedly chain (7), hinge (3) adopts welded chain, and pintle hook lock (4), fastening bolt (5) adopt steel-casting.

Using method of the present utility model is: during work high above the ground, platform (2) is anchored on the electric pole (1) by said procedure with support angle (8), dop (2), hinge (3), pintle hook lock (4), fastening bolt (5), make itself and electric pole (1) be one, the people stands on platform (2) and goes up operation, time spent not, each parts is pulled down, and then realized goal of the invention.
