Examples

Referring to fig. 1 to 8, the present embodiment provides a novel bolting machine 1000, where the novel bolting machine 1000 includes: the self-adaptive nut adjusting mechanism comprises a machine body 300, a control device (not shown), a positioning device (not shown), a traveling device 200, a lifting device 400 and the self-adaptive nut adjusting mechanism 100. The control device, the positioning device, the traveling device 200, and the lifting device 400 are all installed on the machine body 300.

After the adjusting cylinder 130 is matched with the nut, the control driver drives the adjusting cylinder 130 to rotate, so that the nut is rotated. The direction of the driver driving the adjusting cylinder 130 to rotate is controlled, so that the nut can be screwed and unscrewed.

Wherein, in the using process, when the nut needs to be adjusted, the adjusting cylinder 130 of the self-adaptive nut adjusting mechanism 100 is matched with the nut. During the mating process, even if the nut is not completely aligned with the adjustment barrel 130, the adjustment barrel 130 can be quickly aligned with the nut and accurately mated due to the two-dimensional freedom of movement between the mounting platform 110 and the adjustment arm 120 and the ability of the adjustment barrel 130 to swing freely relative to the adjustment arm 120.

Through this design, self-adaptation nut adjustment mechanism 100 can carry out passive, self-adaptation formula position control according to the concrete position of nut to under the condition that the assurance nut in advance is not adjusted well with adjusting a barrel 130, adjust barrel 130 also can align and the accurate cooperation with the nut through the adaptability regulation of self-adaptation nut adjustment mechanism 100.

The structure is simple, and the use and the implementation are convenient.

In general, the novel bolt machine 1000 can effectively reduce the probability of blocking in the construction process, effectively ensure the continuity and smoothness of construction, and meanwhile, significantly reduce the mechanical loss of the adjusting part for adjusting the nut, and effectively prolong the service life. The structure is simplified, and the use and the implementation are more convenient.

In this embodiment, the adjusting cylinder 130 includes a cylinder body 131 and a connecting column 132 coaxially connected, the connecting column 132 is hinged to the adjusting arm 120 to allow the adjusting cylinder 130 to have a swinging freedom with respect to the adjusting arm 120, and an inner cavity of the cylinder body 131 is configured to fit a nut. Wherein, the outer diameter of the cylinder body 131 is larger than that of the connecting column 132. The cartridge body 131 and the connecting post 132 are connected by a floating joint. Through this design, further improved the adaptation effect of adjusting a section of thick bamboo 130, further reduced the dead probability of card.

Further, along the axial direction of the adjusting cylinder 130, the length of the inner cavity of the adjusting cylinder 130 is larger than the length of the screw cap. Optionally, the length of the inner cavity of the adjustment cylinder 130 is greater than or equal to 2 times the length of the nut in the axial direction of the adjustment cylinder 130. Further optionally, the length of the inner cavity of the adjustment cylinder 130 is greater than or equal to 3 times the length of the screw cap along the axial direction of the adjustment cylinder 130. But is not limited thereto. Through will adjusting a section of thick bamboo 130 extension, the length of the inner chamber of adjusting a section of thick bamboo 130 is greater than the nut in the time, has improved the cooperation intensity with the nut effectively to prevent that the nut from deviating from at the rotating in-process, improved equipment operation security.

The inner cavity of the cylinder body 131 of the adjusting cylinder 130 accommodates a spring 133, and the spring 133 is connected to an inner wall of the adjusting cylinder 130 on a side close to the adjusting arm 120. Optionally, naturally, the difference between the length of the inner cavity of the adjusting cylinder 130 and the length of the spring 133 along the axial direction of the adjusting cylinder 130 is smaller than the length of the nut. In this embodiment, the spring 133 extends to the mouth of the inner cavity of the adjustment barrel 130. With this design, when the adjustment cylinder 130 needs to be separated from the nut after the nut is adjusted, the spring 133 can effectively promote the separation of the two. Particularly, in the process of screwing the nut off the screw, the screwed nut can be smoothly ejected out of the adjusting cylinder 130 under the action of the spring 133, so that the nut is timely ejected, and the continuity of nut adjustment is guaranteed.

In the present embodiment, the adjusting cylinder 130 is disposed parallel to the mounting platform 110 relative to the swinging axis of the adjusting arm 120, and the adjusting cylinder 130 passes through the central axis of the adjusting arm 120 relative to the swinging axis of the adjusting arm 120. Specifically, the adjusting arm 120 slides with the mounting platform 110, and along the surface of the mounting platform 110, the adjusting arm 120 has a first sliding direction and a second sliding direction, and the adjusting arm 120 can slide in a reciprocating manner along the first sliding direction and the second sliding direction, respectively. The first sliding direction and the second sliding direction are perpendicular. The oscillation axis of the adjustment cylinder 130 with respect to the adjustment arm 120 is parallel to either the first sliding direction or the second sliding direction.

Further, the adjusting arm 120 is disposed below the mounting platform 110 and is disposed perpendicular to the mounting platform 110, and the adjusting cylinder 130 is disposed below the adjusting arm 120. In a natural state, the adjustment cylinder 130 naturally droops, and the adjustment arm 120 and the adjustment cylinder 130 are coaxially disposed.

It should be noted that, the actuator installed in the adjusting arm 120 for driving the adjusting cylinder 130 to rotate may be embedded in the adjusting arm 120, and the adjusting cylinder 130 may be directly hinged to the power output shaft of the actuator. Furthermore, the adjustment arm 120 may also be directly replaced by a drive. And is not limited thereto.

Further, the opening of the adjusting cylinder 130 may be smoothed. A guide surface 134 is provided at an opening of the adjusting cylinder 130, and the guide surface 134 is connected between an inner sidewall of the adjusting cylinder 130 and an end wall of the adjusting cylinder 130. The distance between the guide surface 134 and the central axis of the adjustment cylinder 130 decreases in the axial direction of the adjustment cylinder 130 and in the direction directed toward the inside of the adjustment cylinder 130. Through the design, in the process of matching the adjusting cylinder 130 and the nut, the guide surface 134 can effectively guide the nut, so that the nut accurately and smoothly enters the inner cavity of the adjusting cylinder 130, the adjusting cylinder 130 is matched with the nut quickly and accurately, and the mechanical loss of the adjusting cylinder 130 can be reduced.

In the present embodiment, the running gear 200 includes: a driving traveling mechanism 210 and a driven mechanism 220. The active traveling mechanism 210 is installed at the bottom of the body 300. The driving running mechanism 210 is used for matching with one side rail, and the driven mechanism 220 is used for matching with the other side rail. Wherein, the driving running gear 210 and the driven gear 220 are connected so that the driven gear 220 can follow the driving running gear 210.

In the using process, the novel bolt machine 1000 only needs the driving walking mechanism 210 to provide driving force, and the driven mechanism 220 is driven by the driving walking mechanism 210 to move along with the driving walking mechanism 210, so that the driving part is effectively simplified. In addition, because the driven mechanism 220 is arranged, and the driving travelling mechanism 210 and the driven mechanism 220 are respectively arranged on the rails at two sides, after the driving travelling mechanism 210 and the driven mechanism 220 are connected, a lever structure is formed in the width direction of the rails.

When the novel bolt machine 1000 works, even though the novel bolt machine 1000 has a tendency of 'bounce' phenomenon, the tendency of 'bounce' appears on one side where the driving walking mechanism 210 is located, and one side where the driven mechanism 220 is located can be regarded as a fulcrum, and the connecting structure of the driving walking mechanism 210 and the driven mechanism 220 provides a longer force arm for the driving walking mechanism 210, so that the probability of 'bounce' phenomenon on one side where the driving walking mechanism 210 is located is effectively reduced.

For a traditional bolt machine, in order to reduce the probability of occurrence of a 'bouncing' phenomenon as much as possible, the weight of the machine body is generally larger, which greatly increases the installation and transportation burden of the machine, and even a hoisting device is needed, so that the use is very inconvenient. The scheme design of this application has reduced the degree of dependence of novel bolt machine 1000 to self weight effectively, can subtract heavy great space of providing for equipment. Due to the moment arm structure of the driving walking mechanism 210 and the driven mechanism 220, even if the weight of the equipment is reduced, the phenomenon of 'bounce' can be effectively prevented.

The structure of the walking device 200 of the novel bolt machine 1000 is effectively simplified, the running stability can be effectively improved, the probability of occurrence of the phenomenon of 'bounce' is reduced, and the walking device has positive significance for reducing the whole weight of the novel bolt machine 1000 and improving the running safety of the novel bolt machine 1000.

In this embodiment, neither the driving traveling mechanism 210 nor the driven mechanism 220 is provided with a hugging wheel.

For the conventional bolt machine, in order to further reduce the probability of occurrence of the phenomenon of 'bounce', the weight of the machine body is relatively large, and the holding wheels are generally arranged to be matched with the rails. This makes the installation and removal process of the device more cumbersome.

The technical scheme of this application has adopted initiative running gear 210 and the arm of force structure of follower 220 two, has reduced the reliance of novel bolt machine 1000 to holding the wheel tightly.

Further, the driving traveling mechanism 210 and the driven mechanism 220 are detachably connected. The driven mechanism 220 comprises a walking wheel 221 and a connecting shaft 222, and the walking wheel 221 is connected with the driving walking mechanism 210 through the connecting shaft 222. The travelling wheels 221 and the active travelling mechanism 210 are detachably connected with the connecting shaft 222. Through the design, the whole mechanism of the walking device 200 is more modularized, and the installation, the disassembly and the transportation are more convenient.

In order to further improve the effect of the moment arm structure of both the driving traveling mechanism 210 and the driven mechanism 220, the connection shaft 222 is disposed perpendicular to the rail.

Further, the active traveling mechanism 210 includes a first engaging wheel 211 for engaging with an upper surface of the rail and a second engaging wheel 212 for engaging with both sides of the rail. This structure is more convenient for install, also can ensure the stability of novel bolt machine 1000 operation effectively. It is understood that the active traveling mechanism 210 further includes a driving member (not shown) for driving the first engaging wheel 211 and the second engaging wheel 212, which will not be described herein.

In other embodiments of the present invention, the driven mechanism 220 can be replaced by another driving traveling mechanism 210 with the body 300 installed. That is, the driven wheel of the driven mechanism 220 may be replaced with a structure of the driving traveling mechanism 210, so that the new bolting machine 1000 has a symmetrical structure. In this way, the bolts of the rails on both sides can be simultaneously handled. In addition, can also set up the novel bolt machine 1000 of multiunit along the track, make these novel bolt machines 1000 work simultaneously, just can handle multiunit bolt simultaneously. The arrangement of the new bolt driving machine 1000 may be various, but is not limited thereto.

To sum up, the embodiment of the utility model provides a novel bolt machine 1000 can reduce effectively and the dead probability of card appears in the work progress, has ensured the continuity and the smoothness nature of construction effectively, still is showing the mechanical loss who has reduced the regulation position that is used for adjusting the nut simultaneously, has prolonged life effectively. The structure is simplified, and the use and the implementation are more convenient.
