Abstract

The utility model discloses a stamping strain clamp comprising a suspension body, a pressing plate, and U-shaped bolts. The U-shaped bolt are buckled at the lower end of the front arm of the suspension body. The pressing plate penetrates from the opening ends of the U-shaped bolts and is pressed at the upper end of the front arm of the suspension body by nuts. On the basis of cooperation of the U-shaped bolts with a wire groove at the lower end of the front arm of the suspension body, a cable is supported and pressed in the wire groove of the front arm by the bottoms the opening ends of the U-shaped bolts, so that the installing requirement of the cable is met. The stamping strain clamp with the simple structure can be installed and repaired easily; the connecting strength meets the requirements of various using environments; the manufacturing process of all assemblies is simplified; the production cost is lowered; and the processing environment requirement is low. Moreover, the clamp has the high mechanical performance; the using reliability in the transmission line is enhanced; and objectives of energy reduction and loss reduction are achieved.

Description

A kind of punching press strain clamp

Technical field

The utility model relates to the transmission line technical field, especially relates to a kind of punching press strain clamp.

Background technology

The punching press strain clamp is mainly used in setting up of transmission line cable, especially externally the strength and stability that the comparatively complicated severe zone of terrain environment and climatic environment is used traditional punching press strain clamp to be set up electric wire is not easy to meet the requirement of installing, easily cause the destabilizing factor that affects safe operation, cause security risk, therefore urgently punching press strain clamp structure is optimized and improves to meet the requirement of security of operation.

The utility model content

In order to overcome above-mentioned existing technological deficiency, the purpose of this utility model is to provide a kind of bonding strength high, simple in structure and be easy to install, and meets the punching press strain clamp that is applicable to various environments for use.

In order to achieve the above object, the utility model is achieved through the following technical solutions: a kind of punching press strain clamp, by the body that dangles, pressing plate and U-bolt, formed, described U-bolt snaps onto the forearm lower end of the body that dangles, described pressing plate penetrates from U-bolt mouth end, and be pressed in the forearm upper end of the body that dangles by nut, utilize U-bolt to coordinate with the wire casing of the forearm lower end of the body that dangles, by U-bolt mouth bottom section, the cable top is pressed in the wire casing of forearm, meets the installation requirement that sets up cable.

As preferably, the described body that dangles, pressing plate and U-bolt adopt respectively structural carbon steel material processed, aluminium material and non-ferromagnetic material to make, be conducive to the alleviator total weight, do not form toroid after each assembled simultaneously, can not produce corona in defeated modified line road, the electricity greatly reduced in delivery circuit damages.

Compared with prior art, the beneficial effects of the utility model are:

1, simple in structure, be easy to I&M, bonding strength meets the requirement of various environments for use;

2, the simplified manufacturing process of assembly, reduced production cost, and processing environment requires low;

3, mechanical performance is high, has strengthened the reliability of using in the transmission line, more saving energy and decreasing loss.

The accompanying drawing explanation

The utility model will illustrate by example and with reference to the mode of accompanying drawing, wherein:

Fig. 1 is the utility model structural representation.

Mark in figure: the body 1 that dangles, pressing plate 2, U-bolt 3, forearm 1-2, cable 4.

Embodiment

Below in conjunction with accompanying drawing, the utility model is described in detail.

In order to make the purpose of this utility model, technical scheme and advantage clearer, below in conjunction with drawings and Examples, the utility model is further elaborated.Should be appreciated that specific embodiment described herein is only in order to explain the utility model, and be not used in restriction the utility model.

Embodiment 1, as shown in Figure 1, this device is a kind of punching press strain clamp, by the body 1 that dangles, pressing plate 2 and U-bolt 3 form, described U-bolt 3 snaps onto the forearm 1-2 lower end of the body 1 that dangles, described pressing plate 2 penetrates from 3 mouthfuls of ends of U-bolt, and be pressed in the forearm 1-2 upper end of the body 1 that dangles by nut, carry out cable while setting up, in advance each building block is assembled as above-mentioned mode, unclamp the nut be screwed on U-bolt 3 screw mandrels, now between the wire casing of U-bolt 3 and forearm 1-2, enough spaces are arranged, cable is from forearm 1-2 wire casing port, through U-bolt 3 openend bottom U-shaped mouths, pass, now tighten the nut on U-bolt 3 screw mandrels, pressing plate 2 is pressed on to the forearm 1-2 upper end of the body 1 that dangles, U-bolt 3 is with respect to the forearm 1-2 relative motion that makes progress, cable 4 is clamped in the wire casing of forearm 1-2, this device utilizes U-bolt 3 to coordinate with the wire casing of the forearm 1-2 lower end of the body 1 that dangles, by 3 mouthfuls of bottom sections of U-bolt, cable 4 tops are pressed in the wire casing of forearm 1-2, meet the installation requirement that sets up cable.

Embodiment 2, on the basis of embodiment 1, the described body 1 that dangles, pressing plate 2 and U-bolt 3 are carried out to decision design, dangle body 1, pressing plate 2 and U-bolt 3 adopts respectively structural carbon steel material processed, aluminium material and non-ferromagnetic material to make, be conducive to the alleviator total weight, do not form toroid after each assembled simultaneously, can not produce corona in defeated modified line road, the electricity greatly reduced in delivery circuit damages.

The foregoing is only preferred embodiment of the present utility model; not in order to limit the utility model; all any modifications of doing within spirit of the present utility model and principle, be equal to and replace and improvement etc., within all should being included in protection range of the present utility model.
