DETAILED DESCRIPTION

[0019] The present invention will be further described in detail below with reference to the accompanying drawings and through examples. The following examples are provided to explain the present invention, but the present invention is not limited to the following examples.

[0020] Example

[0021] See also Figures 1 to 5 The rail clamp wheel adjustment device of this embodiment includes a base 1, an adjustment device 2 and a sliding body 3. The adjustment device 2 is rotatably installed at the center position of the base 1. The adjustment device 2 is installed through the base 1.

The sliding bodies 3 are symmetrically installed on both sides of the base body 1, and the track clamping wheels 4 are respectively installed on the upper parts of the two sliding bodies 3.

[0023] In this embodiment, cylindrical slide bars 13 are arranged at the four corners of the base 1, a partition plate is provided inside the base 1 to divide the base 1 into a first partition layer 14 and a second partition layer 15, a through hole with a keyway is provided at the center of the base 1, and a friction bump 12 is provided at the middle position of the outer side of the base 1.

[0024] In this embodiment, a slide bar 26 is disposed on the inner side of the first dividing layer 14 and the second dividing layer 15, and a hollow space is provided between the two dividing layers.

[0025] The adjusting device 2 in this embodiment is configured as a rocker arm type, which is formed by connecting a rotating rod 23 with an adjusting arm 21. The rotating rod 23 is provided with two threaded surfaces 230 and two key platforms 231. The threaded surface 230 is provided with a locking nut 22, and the locking nut 22 is connected with the threaded surface 230 in a cooperative manner.

[0026] The connecting rod mechanism in this embodiment is composed of a rotating member 24, a connecting rod 25, and a slider 27. A through hole with a keyway is provided in the middle of the rotating member 24, and hinge holes are symmetrically provided at both ends. The connecting rod 25 is symmetrically connected to the hinge holes of the rotating member 24, and the slider 27 is hinged to the other end of the connecting rod 25.

[0027] The slider 27 in this embodiment is an I-shaped structure, and the slide bar 26 and the slider 25 are slidably matched.

[0028] The base 1 in this embodiment is an assembly, which is formed by a welded internal main frame and base plates 11 at both ends being threadedly connected. The connection between the main frame and the base plate 11 divides the interior of the base 1 into parts, namely, a partition layer 14, a hollow layer, and a partition layer 2 15, wherein the partition layer 14 and the partition layer 15 have the same width, and connecting rod mechanisms are respectively arranged in the two partition layers, and the connecting rod mechanisms are installed and rotated based on the rotating member 24.

[0029] A through hole with a keyway is provided at the center position of the rotating member 24 in this embodiment, and connecting rods 23 are hinged at both ends of the rotating member 24. A slider 27 is hinged at the other end of the connecting rod 23. The cross-section of the slider 27 is I-shaped, and a slide bar 26 is fixedly installed on the inner side of the base plate 11 and the main frame. The groove of the slider 27 is engaged with the slide bar 26, and the slider 27 is slidably connected to the slide bar 26. Slide bars 13 are provided at the four corners of the base body 1, and two sliding bodies 3 are symmetrically installed with the vertical center plane of the base body 1 as a reference.

[0030] The sliding body 3 in this embodiment includes a sliding box 31, a push rod 32 and a sliding groove 33. The main structure of the sliding body 3 is the sliding box 31. The sliding box 31 is set as a hollow box structure with one side exposed, and sliding grooves 33 are set at the four corners inside the sliding box 31. The sliding groove 33 is slidably connected to the sliding rod 13 on the base 1. Two push rods 32 are set at the middle position inside the sliding box 31. One end of the push rod 32 is fixedly connected to the bottom end of the sliding box 31, and the other end is fixedly connected to the hinged slider 27.

[0031] The adjusting device 2 in this embodiment includes an adjusting arm 21, a locking nut 22 and a rotating rod 23. The adjusting device 2 is in the form of a crank, one end of which is connected to the adjusting arm 21 through an arc transition, and the other side away from the adjusting arm 21 is provided with a rotating rod 23. Two threaded surfaces 230 and two key platforms 231 are provided on the rotating rod 23. Two locking nuts 22 are also matched at the two threaded surfaces 230. Friction protrusions 12 with through holes are provided on the end surfaces of the two substrates 11. The diameter of the through hole here is larger than the diameter of the rotating rod 23 plus the distance of the key platform 231. The friction protrusion 12 is used to lock with the locking nut 22. The through hole provided on the partition at the center position of the base 1 is a hole with a keyway. This facilitates the adjustment device 2 to pass from one end of the base 1 to the other end, and also facilitates the key cooperation between the rotating rod 23 and the rotating member 24, so that the rotating member 24 can rotate under the rotation of the adjustment arm 21 and the rotating rod 23, thereby driving the connecting rod 23 to swing, and driving the slider 27 to slide based on the slide bar 26. Since one end of the slider 27 is connected to the push rod 32, the sliding of the slider 27 will push the push rod 32 to move. The displacement of the push rod 32 will drive the slide boxes 31 at both ends of the base 1 to slide synchronously inward and outward based on the sliding cooperation between the slide bar 13 and the slide groove 33. The track clamping wheels 4 are respectively installed on the upper part of the two sliding bodies 3, and the center distance of the track clamping wheels 4 will change with the synchronous displacement of the slide box 31.

[0032] The two track clamping wheels 4 in this embodiment clamp the side surfaces of the guide rail 5 and are distributed on both sides of the guide rail 5 for rolling operation. This requires that the track clamping wheels 4 have a certain degree of pressure fit on the side surfaces of the guide rail 5 to ensure the rolling friction force required for the track clamping wheels 4 to operate on the guide rail 5; in actual applications: 1) When the track clamping wheels 4 are loose and need to be adjusted by the machine: slightly loosen the locking nut 22 on the side surface of the end plate; rotate the adjusting arm 21 to retract the sliding body 3. At this time, the center distance between the two track clamping wheels 4 will become smaller. After adjusting to the appropriate force, tighten the locking nuts 22 on both sides of the base plate 11, limit the adjusting arm 21, and prevent the adjusting device 2 from loosening; 2) When the track clamping wheels 4 are installed too tightly and the track clamping wheels 4 do not operate smoothly: also loosen the locking nut 22 first and then adjust. The adjustment direction is exactly opposite to the above, and the remaining steps are the same as above.
