Technical field
The utility model relates to a kind of spanner, specifically is a kind of hand electric wrest fixing spanner.
Background technology
Along with the fast development of high-speed railway, the safe operation of railway contact line becomes an important topic.Because the bolt of living surely on the contact net on clamp and the dropper line is loosening easily in train high-speed cruising process, thereby makes the locomotive contact produce electric spark, the life-span of having reduced circuit and locomotive contact.If screw thread comes off and the locomotive collision in the locomotive high-speed cruising, then can produce serious consequence.At present, main dependence manually tights a bolt and edits with torque spanner then in operation process, inefficiency and can not guarantee installation quality.Adopting this spanner, can effectively guarantee thread connection quality, increase work efficiency, is the bolted ideal tools of railway contact line.
The utility model content
In order to overcome the shortcoming that above-mentioned prior art exists, the purpose of this utility model is to provide a kind of hand electric wrest fixing spanner of the quality of not only can having increased work efficiency but also can guarantee to be threaded.
For addressing the above problem, the utility model is by the following technical solutions: this hand electric wrest fixing spanner, comprise spanner, wrench body, described wrench body comprises a pair of intermeshing bevel gear, one of them bevel gear is connected with the output of a planet reducing gear is coaxial, and the input of described planetary gear speed reducing mechanism connects a direct current brush motor; Another bevel gear is connected with described spanner is coaxial; Described bevel gear, planetary gear speed reducing mechanism, brush direct current motor all are arranged in the shell, also comprise the strain-type torque sensor, and the setting of described strain-type torque sensor is connected in the enclosure and with shell, and the rear end of described shell is provided with handle; The outer surface of handle is provided with a guidance panel, and this guidance panel is provided with action button and display screen; Also comprise SCM Based control module and battery; Described brush direct current motor, strain-type torque sensor, guidance panel are electrically connected with control module respectively.
As further technical scheme of the present utility model:
In this hand electric wrest fixing spanner, described bevel gear is a spiral bevel gear.
In this hand electric wrest fixing spanner, described control module and described battery are located in the insulation shell, and control module is connected with described brush direct current motor, guidance panel, strain-type torque sensor by an external cable.
In this hand electric wrest fixing spanner, described battery is the explosion-proof lithium battery group of rechargeable type.
The beneficial effects of the utility model are: it is to rotate by the control brush direct current motor, drives the planetary gear speed reducing mechanism spiral bevel gear, finally tights a bolt.Moment is to transmit signals to control module by the strain-type torque sensor, stops automatically after moment reaches, and moment is shown.The power supply of spanner is by the rechargeable type lithium battery power supply.Be applicable to field work.This spanner efficient height, the precision height, volume is little, in light weight, flexible to operation, can improve the contact net quality of connection, and operating efficiency reduces labour intensity, is applicable to the operation that is threaded of railway contact line.
Description of drawings
Below in conjunction with drawings and Examples the utility model is described further:
Fig. 1 is the structural representation of the utility model embodiment,
Among the figure: 1 bevel gear; 2 strain-type torque sensors; 3 planetary gear speed reducing mechanisms; 4 brush direct current motors; 5 guidance panels; 6 handles; 7 cables; 8 control modules; 9 batteries; 10 spanners, 11 shells.
The specific embodiment
As shown in Figure 1, this hand electric wrest fixing spanner comprises spanner 10, wrench body, and described wrench body comprises a pair of intermeshing bevel gear 1, is used for the moment commutation, makes more convenient operation.
This bevel gear 1 is selected spiral bevel gear for use, i.e. spiral bevel gear, and its stable drive, noise is little, and bearing capacity is big.One of them bevel gear is connected with the output of a planet reducing gear 3 is coaxial, and the input of planetary gear speed reducing mechanism 3 connects a direct current brush motor 4; Another bevel gear and 10 coaxial connections of spanner.The planetary gear speed reducing mechanism volume is little, efficient is high; The big moment of brush direct current motor, and moment and rotary speed property are good.
Described bevel gear 1, planetary gear speed reducing mechanism 3, brush direct current motor 4 all are arranged in the shell.
One strain-type torque sensor 2 also is set in the shell 11, and strain-type torque sensor 2 directly is connected with shell 11, has reduced other links, makes the spanner volume little, in light weight.Strain-type torque sensor 2 is with the built-in output of signal amplification circuit 4-20mA signal.Adopt strain-type torque sensor precision height, cost low.
The rear end of shell 11 is provided with handle 6, and the outer surface of handle 6 is provided with a guidance panel 5, and this guidance panel 5 is provided with action button and display screen.Guidance panel is simple, and easily operation only needs the push button, and spanner is just started working, reach quit work automatically after the torque setting value and point out whether qualified.Display screen can show moment, qualified indication, battery alarm, overcurrent protection etc.
This hand electric wrest fixing spanner also comprises SCM Based control module 8 and battery 9.Strain-type torque sensor 2 is electrically connected with control module, the torque signals that strain-type torque sensor 2 collects to control module 8 transmission.Control module 8 adopts the high-performance single-chip microcomputer as data processing core, built-in 12 A/D, and the data after the collection are done digital filtering by software, to guarantee the authenticity of data.Control module 8 is connected with brush direct current motor 4 by the drive motors element, and the drive motors element adopts dc solid-state relay, has reduced noise, has improved service life.Guidance panel 5 also is connected with control module.The control module that single-chip microcomputer is formed, volume is little, applying flexible, cost are low.
