Description

A kind of nut dismounting device
Technical field
The utility model relates to a kind of nuts to remove device.
Background technique
Pre-buried part bolt, bolt were embedded into concrete in the construction time in the concrete of hydroelectric power plant's water wheel chamber, after Phase is concrete curing, and bolt can not be replaced again.Due to humid environment, although bolt surface has smeared slushing oil, in spiral shell Bolt and nut connection screw thread gap can still generate corrosion, cause not using normally by under nut dismounting in maintenance using spanner Rust remover is difficult to go deep into inside gap, and practical application effect is poor, if cutting nut using angle grinder, easily causes bolt thread The damage of unrepairable.
Summary of the invention
Technical problem to be solved in the utility model is:Existing nut and bolt corrosion mentioned in the background art Afterwards, the technical issues of nut can not be dismantled normally.
In order to solve the above technical problems, the technical solution adopted in the utility model is:
A kind of nut dismounting device, including cutter head, hook members, sleeve, screw rod, handle and bar,
The one end of sleeve is arranged in hook members, and the one end of screw rod is arranged in bar, and screw portion is located at hub internal bore In and bar be located at except sleeve;Screw rod is connected with hub internal bore by screw thread pair;Cutter head is inserted into hub internal bore, cutter head and hook-type Component is located at the same end of sleeve;Handle is arranged on sleeve outer surface.
Blade is arranged in improvement to technical solutions of the utility model, cutter head one end, and the other end face is spherical surface.This is practical new The cutter head of lathe in the prior art can be used in type cutter head, and hardness is high, can effectively cut away corrosion back nut.
Improvement to technical solutions of the utility model, cutter head and hub internal bore are clearance fit.Cutter head and hub internal bore Clearance fit is effective to ensure that cutter head can be passed in and out smoothly under the promotion of screw rod.
Improvement to technical solutions of the utility model, handle are located at the interposition of length sleeve with sleeve weld and handle It sets, the axis of handle and the axis perpendicular of sleeve.Handle and sleeve vertical design are effectively guaranteed firmly uniform.
Improvement to technical solutions of the utility model, bar and screw rod weld, the axis of bar and the axis perpendicular of screw rod.Bar With screw rod vertical design, it is effectively guaranteed firmly uniform.
The utility model compared with prior art, the beneficial effect is that:
1, the nut of the utility model is removed device and is converted the power of lesser circumferencial direction to biggish by screw thread Radial force saves manpower.
2, the nut of the utility model removes device, suitable for handling the nut of different model specification.
3, the nut of the utility model removes device, effective protection bolt thread.
3, the nut of the utility model removes device, and hook members are provided with opening, install and use convenient for the device.
3, the nut of the utility model removes device, and device only needs manually can easily remove nut, is not necessarily to other power The energy, personnel's operating environment are preferable.
Detailed description of the invention
Fig. 1 is the structural schematic diagram that nut removes device.
Specific embodiment
Technical solutions of the utility model are described in detail below, but the protection scope of the utility model is not limited to The embodiment.
To keep the content of the utility model more obvious and easy to understand, done further below in conjunction with attached drawing 1 and specific embodiment Description.
In order to make the purpose of the utility model, technical solutions and advantages more clearly understood, below in conjunction with attached drawing and implementation Example, the present invention will be further described in detail.It should be appreciated that specific embodiment described herein is only to explain this Utility model is not used to limit the utility model.
Embodiment:
As shown in Figure 1, for the present embodiment nut remove device, including cutter head 1, hook members 2, sleeve 3, screw rod 4, Hand 5 and bar 6.
As shown in Figure 1, blade is arranged in 1 one end of cutter head, the other end face is spherical surface.Lathe in the prior art can be used in cutter head Cutter head, hardness is high, can effectively cut away corrosion back nut.
As shown in Figure 1, hook members 2 are provided with opening, installed and used convenient for the device;Sleeve 3 is arranged in hook members 2 One end, bar 6 are welded on the one end of screw rod 4, the axis of bar 6 and the axis perpendicular of screw rod 4.Bar 6 is vertical with screw rod 4 to be set Meter is effectively guaranteed firmly uniform.4 part of screw rod is located in 3 inner hole of sleeve and bar 6 is located at except sleeve 3;Screw rod 4 with 3 inner hole of sleeve is connected by screw thread pair;Cutter head 1 is inserted into 3 inner hole of sleeve, and cutter head 1 and 3 inner hole of sleeve are clearance fit.Cutter head 1 With the clearance fit of 3 inner hole of sleeve, it is effective to ensure that cutter head can be passed in and out smoothly under the promotion of screw rod.Cutter head 1 and hook-type Component 2 is located at the same end of sleeve 3;Handle 5 is welded on 3 outer surface of sleeve and handle 5 is located at the interposition of 3 length of sleeve It sets, the axis of handle 5 and the axis perpendicular of sleeve 3.Handle 5 and 3 vertical design of sleeve are effectively guaranteed firmly equal It is even.
The course of work of corrosion nut is removed using the present apparatus:
Cutter head 1 is arranged close to 2 side of hook members, screw rod 4 screws in the inner cavity screw hole of sleeve 3, by the nut of corrosion It is stuck between cutter head 1 and hook members 2, handle 5 of holding with a firm grip, swingle 6 makes screw rod 4 threadingly promote cutter head 1, and 1 hardness of cutter head is long-range In in nut, the constantly cutting pressed-in nut of cutter head 1.When finally cutting is close to bolt for cutter head 1, stops pressure, exits the device, Since nut unilateral side is finished by cutting substantially, easily nut need to can only be taken out with vice, bolt thread will not be by Damage.
This nut removes device and converts biggish radial force by screw thread for the power of lesser circumferencial direction, save Manpower;Suitable for handling the nut of different model specification;Effective protection bolt thread;Hook members are provided with opening, are convenient for the dress It sets and installs and uses;The present apparatus only needs manually can easily remove nut, is not necessarily to other power sources, and personnel's operating environment is preferable.
The parts not involved in the utility model is the same as those in the prior art or can be realized by using the prior art.
As described above, although the utility model has been indicated and described referring to specific preferred embodiment, it must not It is construed to the limitation to the utility model itself.In the spirit and scope for not departing from the utility model that appended claims define Under the premise of, it can various changes can be made in the form and details to it.
