Description

Technical Field

[0001] The utility model relates to the field of machinery, in particular to a guide component. Background Art

[0002] Most of the existing guide heads are equipped with limit rollers, which are used to make the guide heads roll along the side walls (cylinder walls, pipe walls, etc.) to reduce resistance. However, for annular pipes, especially large curved pipes, it is difficult to ensure that the pipes are completely regular in the horizontal and vertical directions during processing. If there are limit rollers in only one direction, either the upper or lower direction, unpredictable vibrations will occur, affecting the stability of the mechanical movement of the equipment. If rollers arranged front and back are set up both above and below, the upper roller (or lower roller) in front and the lower roller (or upper roller) in the rear will be overstressed in the up and down fluctuation area of ​​the pipe (irregular pipe), while the other two rollers will be suspended. In this way, not only will unpredictable vibrations occur, affecting the stability of the mechanical movement of the equipment, but also the running resistance will be caused by excessive force, consuming too much energy, and the pipe and rollers will be damaged due to excessive force. Utility Model Content

[0003] The purpose of the utility model is to provide a wall-adhering rolling guide component to solve the above technical problems.

[0004] The technical problem solved by the present invention can be achieved by adopting the following technical solutions:

[0008] The guide head has a width in the front-rear direction of movement, and the guide head is provided with limit rollers at the front and rear respectively;

[0009] The front part of the guide head is provided with an elastic mechanism providing a downward elastic force, which is called a front elastic mechanism;

[0010] The rear portion of the guide head is provided with an elastic mechanism that provides a downward elastic force, which is called a rear elastic mechanism.

[0011] The utility model uses forces including elastic force to press the rail or pipe at all times on one side of the limiting roller of the guide head, thereby ensuring that the guide head fits the trajectory of the rail or pipe during movement, thereby improving the phenomenon of torsion jamming at the position where the rail or pipe is twisted in the upper and lower directions.

[0012] There is no limit roller below the guide head to limit the upward and downward movement of the guide head. In conventional designs, in order to make the guide head fit the track or pipeline, limit rollers or guide wheels arranged front and back are often set in both the upper and lower directions. However, because the guide head has a width, it is easy to cause twisting and jamming. The utility model eliminates the limit roller in one direction, which can further improve the phenomenon of twisting and jamming in the twisted position of the track or pipeline in the upper and lower directions.

[0013] Preferably, the elastic mechanism is a spring mechanism, a magnetic mechanism, a hydraulic mechanism or a pneumatic mechanism.

The utility model extends the structure of the transmission arm through the structural member, and sets the pressure point directly above the limit roller, so that the force is applied more directly and the capacity loss is reduced; at the same time, the intermediate links of the transmission are reduced, so that the mechanical feedback is faster and more accurate.

[0015] Further preferably, there are two structural members, namely a front structural member and a rear structural member; one force-applying end of the front structural member is connected to the transmission arm, and the other force-applying end extends to the upper part of the position of the guide head relatively to the front of the middle part; one force-applying end of the rear structural member is connected to the transmission arm, and the other force-applying end extends to the upper part of the position of the guide head relatively to the rear of the middle part;

[0016] The force-applying ends of the two structural members extending above the guide head are respectively connected to at least one of the elastic mechanisms. The utility model is provided with structural members and elastic mechanisms at the front and rear positions of the guide head, respectively, so that the front and rear positions can be adjusted respectively, and finally the limiting roller can ensure precise fit with the track or pipeline during movement at a faster speed.

[0017] Further preferably, the structural member includes a bottom plate extending in the direction of the transmission arm, the bottom plate is connected to the transmission arm, the bottom plate is connected to a top plate extending in the direction of the transmission arm through a side plate located above, the top plate is provided with an extension plate extending in the direction of the limiting roller, the extension plate is connected to the elastic mechanism; the bottom plate is used as the force-applying end of the structural member connected to the transmission arm, and the extension plate is used as the connection end of the structural member connected to the elastic mechanism. The utility model optimizes the structure of the structural member, which is not only more stable, but also can deliver the elastic mechanism to the top of the limiting roller by using the structural member, which has the advantages of simple structure and higher stability compared with other connection methods.

[0018] Preferably, the extension plate is provided with an opening extending from top to bottom, a sleeve is fixed in the opening, a screw is threadedly connected to the sleeve, and a compression spring is connected to the lower part of the screw. The present invention uses a compression spring instead of a tension spring, which has been shown in experiments to have a more lasting elastic force, helps to maintain elastic stability and controllability, improves the batch consistency of the equipment, and prolongs the service life. In addition, the utility model is additionally provided with a sleeve and a screw, which can be used to adjust the degree of compression of the compression spring against the guide head, thereby adjusting the magnitude of the elastic force.

[0019] Preferably, the upper parts of the front side wall and the rear side wall of the guide head are respectively fixed with limit roller supports, the limit roller supports are provided with limit rollers, and the bottom of the compression spring abuts against the limit roller supports, so that the force application position of the elastic force is closer to the limit rollers.

[0020] Preferably, each of the two ends of the transmission arm is connected to a guide head, so that the transmission arm is evenly stressed and the guide head rolls more smoothly in and along the annular pipe.

[0021] Preferably, an elastic gasket is provided between the elastic mechanism and the guide head, so as to prevent the elastic mechanism from bumping against the guide head and ensure the service life of the guide head. BRIEF DESCRIPTION OF THE DRAWINGS
