Telescopic damper rod erecting device
Technical field
The utility model relates to a kind of telescopic damper rod erecting device that has the damper rod structure that is used to install, and belongs to machinery manufacturing technology field.
Background technology
In actual production and life, the capital often runs into device and the equipment that has telescopic damper rod structure as cylinder, hydraulic cylinder, vibration absorber, valve, door switch or the like, in 200 kilometers electric motor car groups productions, also damper rod to be installed on the driver's desk, because the retractility of damper rod is very strong, be difficult to fix, and also very strict to the requirement of installation dimension, increased installation difficulty.
Damper rod is to be in free state before installation, its length of stretching out is the longest, but need to install the product or the equipment of damper rod, the installation length of its regulation is to design as required to determine, the installation length that is to say damper rod is less than its drift, damper rod is its effect of competence exertion after installation, so when mounted, must damper rod will be compressed to required installation length by drift earlier.
At present aborning as when running into the installation of damper rod, need manually damper rod to be advanced a segment distance, what make damper rod shortens into the needed length of installation by drift, also need other personnel to be fixed to damper rod on the product or equipment that is mated by various securing members, because the retractility of damper rod is very strong, the artificial damper rod that advances is difficult to once to reach installation requirement, need repeatedly adjust, and, when the installation environment space is very narrow, as when the driver's desk of 200 kilometers electric motor car groups is installed, several people's operation in narrower space simultaneously causes installing very inconvenience, also can bring bigger difficulty to installation, product quality can not guarantee that working strength of workers also can be very high.
Summary of the invention
The utility model main purpose is to address the above problem and is not enough, provide a kind of simple in structure, can regulate the length of damper rod within the specific limits arbitrarily and make its fixing telescopic damper rod erecting device, it can guarantee the installation accuracy of damper rod, reduces labor strength.
For achieving the above object, the technical solution of the utility model is:
A kind of telescopic damper rod erecting device, comprise a stay pipe, and be used for the trimmer that clamping is mounted damper rod, and described trimmer respectively is provided with one at the two ends of described stay pipe, and wherein at least one end by retractor device and stay pipe is scalably movably connected.
Described retractor device comprises a threaded rod and a nut, nut is fixed on the end of described stay pipe, described threaded rod screws out from described nut, the two ends of the trimmer on described threaded rod respectively are provided with a locking nut that is used to lock trimmer, and an opening is set on described trimmer.
Content to sum up, telescopic damper rod erecting device provided by the utility model, cooperate with rotation between the nut by long threaded rod, can be like a cork the length of damper rod be adjusted to needed installation length by drift, and regulates the length of damper rod within the specific limits arbitrarily, and damper rod is remained on the installation length, thereby damper rod is in place, this apparatus structure is simple, and it can guarantee the installation accuracy of damper rod, reduces labor strength.
Description of drawings
Fig. 1 the utility model structural representation;
The structural representation of Fig. 2 the utility model trimmer.
As depicted in figs. 1 and 2, stay pipe 1, trimmer 2, retractor device 3, threaded rod 4, nut 5, locking nut 6, opening 7.
The specific embodiment
Below in conjunction with the accompanying drawing and the specific embodiment the utility model is described in further detail:
As depicted in figs. 1 and 2, a kind of telescopic damper rod erecting device, comprise a stay pipe 1, the clamping damper rod respectively is provided with one at the both ends of stay pipe 1 and is used for the trimmer 2 that clamping is mounted damper rod for convenience, trimmer 2 is provided with opening 7, when damper rod is installed, opening 7 is inserted into two ends of damper rod, play fixation, opening 7 is arranged to strip, can adjust the distance that needs retaining part flexibly.Regulating the clamping direction of trimmer 2 for convenience, all is to adopt the mode that flexibly connects between trimmer 2 and the stay pipe 1.
The utility model can be provided with telescopic mounting 3 by an end at stay pipe 1, also a retractor device 3 can respectively be set at the two ends of stay pipe 1.When only when an end of stay pipe 1 is provided with retractor device 3, can flexibly connect by connected modes such as bearing pins between the trimmer 2 of the other end and the stay pipe 1.
With the two ends at stay pipe 1 retractor device 3 being set respectively below is example, is described in detail as follows:
Retractor device 3 comprises a threaded rod 4 and a nut 5, nut 5 directly is weldingly fixed on the end of stay pipe 1, threaded rod 4 screws out from nut 5, rotation threaded rod 4 just can be regulated the length that threaded rod 4 stretches out from stay pipe 1, thereby the length of easy adjustment whole erection device, above-mentioned two trimmers 2 just are enclosed within on the threaded rod 4 respectively, and trimmer 2 can be done around threaded rod 4 and rotate in a circumferential direction.
For trimmer 2 being fixed on the optional position, a locking nut 6 that is used to lock trimmer 2 respectively is set at the two ends of trimmer 2, the rotation direction of two locking nuts 6 is opposite, like this when trimmer 2 arrives needed position, just can firmly fix the position of trimmer 2 by rotating two opposite locking nuts 6 of rotation direction.
Threaded rod 4 in two retractor devices 3 can be as shown in Figure 1, be arranged to one long, a weak point, a short end can directly replace with bolt, it is to the effect that 2 of trimmers play a fine setting and are locked, and another 4 long of threaded rod plays the effect of main adjusting length.
The process that damper rod is installed with the utility model is as follows: the installation length of at first determining damper rod according to damper rod installation site and designing requirement, by regulating threaded rod 4, make in its precession stay pipe 1, the length adjustment of this erecting device is arrived the approximate location of the installation length of damper rod, two ends that the opening 7 of trimmer 2 are inserted into damper rod are fixed then, regulate the locking nut 6 at trimmer 2 two ends, and then it is trimmer 2 is fixing, again by regulating threaded rod 4, make its precession or screw out stay pipe 1, and then the length of damper rod is carried out trace regulate, its length and installation length are consistent, at last damper rod is installed in the position of need installing and fixing after, trimmer 2 is extracted out from damper rod, just finished the installation of whole damper rod.
Adopt this mounting means, the installation length of damper rod is after determining, just the length of damper rod can be fixed by this erecting device, not change that can be random does not more need the adjustment of repeated multiple times, can guarantee the precision of installing, simultaneously, working strength of workers also can reduce greatly, when mounted, the people who only needs only a few, even only need a people just can finish whole installation exercise.
As mentioned above, given in conjunction with the accompanying drawings and embodiments scheme content can derive the similar techniques scheme.In every case be the content that does not break away from technical solutions of the utility model, to any simple modification, equivalent variations and modification that above embodiment did, all still belong in the scope of technical solutions of the utility model according to technical spirit of the present utility model.
