Abstract

The utility model belongs to the technical field of the installation of cable testing bridge in the building, concretely relates to T type long arm sleeve. The utility model discloses an installation crane span structure that can be quick safe, provide a T type long arm sleeve for fastening lead screw, including sleeve, flexible arm and rotatory handle, the sleeve is connected with flexible arm, and rotatory handle is connected in the end of flexible arm, the sleeve is hierarchic structure, and its path section is equipped with the external screw thread of being connected with the arm that stretches out and draws back, and it has interior hexagonal to open in the section of big footpath, still is equipped with the through -hole of installation lead screw in the sleeve. The lead screw top that utilizes the device will connect expansion bolts can directly be recycled rotatory handle and fasten expansion bolts after being gone into the hole, and whole operation process can be gone on in succession, and can accomplish alone, squeezes into the bolt with the light hammer downtheholely with traditional elder generation, and reuse open end wrench tighten the bolts's mode is compared, and installation time has saved half thely, and efficiency obviously improves, has saved time limit for a project and cost, need not practical stool, has reduced unsafe factor.

Description

A kind of T-shaped long-armed sleeve for fastening screw mandrel
Technical field
The utility model belongs to the mounting technique field of cable testing bridge in building, is specifically related to a kind of T-shaped long-armed sleeve.
Background technology
When laying building cable channel, first erection bridge is needed, often on roof, the suspension bracket of screw mandrel as crane span structure will be fixed with expansion bolt in installation process, conventional method first utilizes rig to hole on roof, then with hand hammer, expansion screw mandrel is squeezed in hole, finally utilize spanner tighten the screws to fix.The method at least needs two workmans to coordinate just to complete, and because of screw mandrel process, can only utilize open-end wrench tighten the screws, efficiency is low, and especially for skyscraper, the installation of crane span structure is comparatively large, often can only drive plan by setting up artificial quantity, adding cost; The method also needs workman's operation on stool, and danger coefficient is high; Simultaneously because screw mandrel is longer, easily screw mandrel being deflected when squeezing into cavity, causing unsightly.
Summary of the invention
The utility model, in order to can erection bridge fast and safely, provides a kind of T-shaped long-armed sleeve for fastening screw mandrel.
The utility model adopts following technical scheme:
For a T-shaped long-armed sleeve for fastening screw mandrel, comprise sleeve, telescopic arm and rotating handles, sleeve is connected with telescopic arm, and rotating handles is connected to the end of telescopic arm;
Described sleeve is hierarchic structure, and its path section is provided with the external screw thread be connected with telescopic arm, has interior hexagonal in the section of large footpath, is also provided with the through hole installing screw mandrel in sleeve.
The utility model has following beneficial effect:
1, workman to utilize long-armed sleeve described in the utility model can complete the installation of screw mandrel on ground fastening, without the need to practical stool, decrease unsafe factor;
2, after utilizing this device that the screw mandrel connecting expansion bolt is headed into hole, can directly recycle rotating handles expansion bolt is fastening, whole operation process can carry out continuously, and a people can complete, first squeezed in hole by bolt with hand hammer with traditional, then compare by the mode that open-end wrench tights a bolt, the set-up time saves half, efficiency significantly improves, and saves duration and cost;
3, the telescopic arm of this device can adjust length as required, can be applicable to the construction site of differing heights;
4, the utility model directly utilizes the interior hexagonal of sleeve to coordinate the fastening installation realizing screw mandrel with the nut of expansion bolt, stressed evenly, there will not be the phenomenon deflected by screw mandrel, install effect more attractive in appearance;
5, sleeve dimensions is various, according to selected expansion bolt size Selection, can be beneficial to and promote the use of.
Accompanying drawing explanation
Fig. 1 is structural representation of the present utility model;
Fig. 2 is the structural front view of sleeve;
Fig. 3 is the structure top view of sleeve;
Fig. 4 is the half sectional view of sleeve;
In figure: 1-expansion bolt, 2-screw mandrel, 3-sleeve, 4-telescopic arm, 5-rotating handles;
Hexagonal in 31-external screw thread, 32-through hole, 33-.
Detailed description of the invention
By reference to the accompanying drawings, detailed description of the invention of the present utility model is described further:
The T-shaped long-armed sleeve for fastening screw mandrel as shown in Figure 1, comprise sleeve 3, telescopic arm 4 and rotating handles 5, sleeve 3 is connected with telescopic arm 4, and rotating handles 5 is connected to the end of telescopic arm 4.
As shown in Figure 2,3, 4, described sleeve 3 is hierarchic structure, and its path section is provided with the external screw thread 31 be connected with telescopic arm 4, has interior hexagonal 33 in the section of large footpath, is also provided with the through hole 32 installing screw mandrel 2 in sleeve 3.
Telescopic arm 4 generally adopts the steel pipe of Φ about 20, and therefore, the size of the external screw thread 31 of sleeve 3 can be fixed, and can mate be connected with telescopic arm 4.And the size of interior hexagonal 33 is determined according to the nut external diameter of expansion bolt 1, the diameter of through hole 32 should be greater than the diameter of screw mandrel 2, so that install screw mandrel 2.
When erection bridge suspension rod, the model of screw mandrel 2 diameter installed first as required and selected expansion bolt 1, select suitable sleeve 3, then sleeve 3 is connected with telescopic arm 4, then the screw mandrel 2 termination being connected expansion bolt 1 directly puts into telescopic arm 4 through the through hole 32 of sleeve 3.Utilize telescopic arm 4 that the expansion bolt 1 exposed is headed into hole, then operate rotating handles 5 and expansion bolt 1 is tightened fixing.
