Abstract
A kind of underground equipment rivet riveting device, comprise screw mandrel, the two ends of described screw mandrel are provided with reverse screw thread, the middle part of described screw mandrel is radially provided with multiple connecting hole inserted for handle, described screw mandrel is installed with a nut respectively on the screw thread at two ends, the described nut of wherein one end is fixed with rivet cover, other end nut is fixed with gripper shoe, described rivet cover is provided with the rivet hole matched with rivet size, described screw mandrel rotarily drives two nuts along screw axis to moving in the opposite direction, thus drives rivet cover and gripper shoe tensioning or unclamp.The utility model has handling ease, and use simple, with low cost, effect stability, the features such as applied range, can be used for the field that any rivet need carry out rivet hot.
Description
Technical field
The utility model relates to a kind of underground equipment rivet riveting device.
Background technology
A kind of a kind of handle based on lever principle is used during the rivet joint rivet hot of current underground equipment, by pressing down the afterburning support rivet of handle with workman, but because the strength pressing down handle needs is larger, the strength of different workmans is inconsistent, make afterburning unstable, rivet is caused well not hold out against, owing to also there will be the phenomenon of shrinkage after rivet, if there is the problem of excesssive gap after rivet does not hold out against and easily makes rivet with the medium of centre, thus making the quality of riveted joint very unstable, rework rate is high.
Utility model content
The purpose of this utility model is to overcome the deficiency of prior art and provides a kind of handling ease, uses simple, with low cost, the underground equipment rivet riveting device of effect stability.
The purpose of this utility model is achieved by following technical proposals:
A kind of underground equipment rivet riveting device, comprise screw mandrel, the two ends of described screw mandrel are provided with reverse screw thread, the middle part of described screw mandrel is radially provided with multiple connecting hole inserted for handle, the two ends of described screw mandrel are installed with a nut respectively, the described nut of wherein one end is fixed with rivet cover, other end nut is fixed with gripper shoe, described rivet cover is provided with the rivet hole matched with rivet size, described gripper shoe is installed on support portion, described screw mandrel rotarily drive two nuts along screw mandrel axially-movable and two nuts move in the opposite direction, thus drive rivet cover and gripper shoe tensioning or unclamp.
The shape of described gripper shoe and the shape size of support portion match.
Connecting hole on described screw mandrel is provided with two.
Described screw mandrel two ends are respectively equipped with forward trapezoidal thread and reverse trapezoidal thread.
Owing to adopting such scheme, this device is by the right-and-left threaded structure of screw mandrel, thus during the screw mandrel made rotation, drive the rivet cover on nut and gripper shoe motion, gripper shoe is supported on support portion, the rivet hole of rivet cover is placed on rivet, make gripper shoe and rivet cover outwards push up pressure by the rotation of screw mandrel simultaneously, reach the object of rivet, due in the process of riveted joint also with pretightning force thus the gap existed with intermediate medium after well eliminating rivet, pass through rotatable handle at rotary screw, make to have an effect stable, and this device due to structure simple, narrow space work can also be entered, a lot of rivet that we do not beat in the past, also can process now.
In sum, the present invention has handling ease, and use simple, with low cost, effect stability, the features such as applied range, can be used for the field that any rivet need carry out rivet hot.
Accompanying drawing explanation
Fig. 1 is structural representation of the present utility model.
Detailed description of the invention
Below in conjunction with accompanying drawing, the detailed description of the invention of underground equipment rivet riveting device is described.
As shown in Figure 1, a kind of underground equipment rivet riveting device, comprise screw mandrel 3, the two ends of described screw mandrel 3 are provided with reverse screw thread, the middle part of described screw mandrel 3 is radially provided with multiple connecting hole inserted for handle, described screw mandrel is installed with a nut respectively on the screw thread at two ends, the described nut 4 of wherein one end is fixed with rivet cover 5, other end nut 2 is fixed with gripper shoe 1, described rivet cover 5 is provided with the rivet hole matched with rivet size, described screw mandrel 3 rotarily drives two nuts along screw axis to moving in the opposite direction, thus drive rivet cover 5 and gripper shoe 1 tensioning or unclamp.The described shape of gripper shoe 1 and the shape size of support portion match, and are installed on support portion, the underground equipment that support portion refers to need the parts of riveting opposite face place of rivet place, can be the rigid elements such as brace summer, support bar or guide rail.Connecting hole on described screw mandrel 3 is provided with two.The screw thread at described screw mandrel two ends is respectively forward trapezoidal thread and reverse trapezoidal thread.
During work, because screw mandrel 3 two ends are just, anti-silk, after rivet hole put into by rivet, rotary screw 3, rivet cover 5 withstands the bottom of rivet, then handle is inserted in the connecting hole of screw mandrel, by rotatable handle screw mandrel 3, make the outwards motion simultaneously of support portion 1 and rivet cover 5, thus by rivet at needs position, owing to applying active force by rotary screw to rivet, after ensureing that screw mandrel is tightened, rivet cover is enough to the pressure of rivet, the rivet arrangement be up to like this is compact, and this device can also enter narrow space work, a lot of rivet that we do not beat in the past, also can process now.
The above, be only this novel concrete case study on implementation and illustrate, can not limit rights protection scope of the present utility model with this.All equivalences done according to the utility model application claims and description change and amendment, all in the scope of the utility model protection.
