Abstract

The utility model discloses a cable support arm, comprising a long arm and a short arm. One end of the long arm and one end of the short arm are vertically connected in an L shape. The long arm possesses a rectangular bolt hole which is coaxially arranged with the long arm. According to the utility model, the distance between the cable support and a wall can be adjusted at will, and even when a wall is not consistent in height, the cable support is kept vertical through the adjustment of a bolt fixing device. In addition, no holes is required at the bottom surface of the cable support, the connection of the cable support and the arm is realized through the connection holes at two ends of the cable support, and the usage is easy to achieve.

Description

A kind of cable testing bridge trailing arm

Technical field

The utility model relates to cable testing bridge, particularly a kind of cable testing bridge trailing arm.

Background technique

In the existing technology, the crane span structure trailing arm that uses in the cable testing bridge installation process all is to make according to fixed dimension in advance, and is highly fixing.When laying crane span structure, run into rugged metope through regular meeting, because crane span structure trailing arm height is nonconforming, need to make again a trailing arm that meets requirement for height usually then and there.So, be very much waste of manpower and material resources, increase cost, and can not satisfy the needs of a large amount of installment works in job site, working efficiency is low.In addition, crane span structure trailing arm of the prior art all is fixing crane span structure from the crane span structure bottom surface, connects the required bolt hole of trailing arm because the crane span structure bottom surface reserves, crane span structure bottom surface punching in installation process, just both are connected with bolt then, and working efficiency is not high.

Summary of the invention

In order to solve the problems of the technologies described above, the utility model provides a kind of cable testing bridge trailing arm, can leave the wall distance by the can regulate crane span structure, and simple in structure, convenient easy-to-use.

The utility model is realized through following technological scheme:

Said crane span structure trailing arm has long-armed and galianconism, a long-armed end and L-shaped vertical connection of galianconism one end.Said long-armed, galianconism is respectively equipped with bolt hole.

The further improved technological scheme of the utility model is that said bolt hole is a rectangle, is coaxially set with long-armed.

The utility model compared with prior art has following obvious advantage:

One, the crane span structure of can regulating arbitrarily of the utility model leaves the wall distance, runs into rugged body of wall, also can keep crane span structure level or vertical through the fixed position of regulating bolt.

Two, the utility model does not need in crane span structure bottom surface punching, can directly utilize the attachment hole at crane span structure two ends to realize and being connected of trailing arm, and is simple and easy to do.

Embodiment

As shown in Figure 1, a kind of cable testing bridge trailing arm, crane span structure trailing arm 1 have long-armed 2 with galianconism 3, long-armed 2 one ends and L-shaped vertical connection of galianconism 3 one ends.Be respectively equipped with

bolt hole

21,31 on said long-armed 2, the galianconism 3.Said bolt hole 21 is a rectangle, and long-armed 2 is coaxially set.For attractive in appearance, rectangle bolt hole 21 two ends can be semicircle.

As shown in Figure 2; During cabling crane span structure 4, two trailing arms 1 place cable testing bridge 4 both sides, near cable testing bridge 4; Use bolt 5 that galianconism 3 is fixed on metope 6; Adjust the position of cable testing bridge 4, long-armed 2 bolt hole of crane span structure attachment hole 41 and trailing arm 1 is aimed at, trailing arm 1 is connected fixing with crane span structure 4 with bolt 5.

If actual demand also can be in any local punching of crane span structure both sides, as be connected fixing the use with trailing arm.

Claims

1. cable testing bridge trailing arm, it is characterized in that: said crane span structure trailing arm (1) has long-armed (2) and galianconism (3), long-armed (2) one ends and L-shaped vertical connection of galianconism (3) one ends; Be respectively equipped with bolt hole (21,31) on said long-armed (2), the galianconism (3).

2. a kind of cable testing bridge trailing arm according to claim 1 is characterized in that: said bolt hole (21) is a rectangle, is coaxially set with long-armed (2).
