DETAILED DESCRIPTION
[0024] The following will be combined with the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments of the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.
[0025] Example 1: Figure 1~Figure 5 As shown, this embodiment proposes a railway through-ground wire protection pipe clamp, including a clamp body 1, an upper support plate 3 and a lower support plate 4, the upper support plate 3 is installed on the outer wall of one side of the clamp body 1, the lower support plate 4 is installed on the outer wall of the clamp body 1 away from the upper support plate 3, a movable cavity 9 is arranged inside the upper support plate 3, a turntable 15 is movably installed on the bottom end of the movable cavity 9, a rotating shaft 10 is welded at the center position of the turntable 15, a transmission block 11 is installed on the outer wall of the rotating shaft 10, one end of the lower support plate 4 is connected to a first telescopic rod 7, the outer wall of the first telescopic rod 7 is movably installed with a first clamp 5, the end of the first telescopic rod 7 away from the lower support plate 4 is fixedly installed on the bottom end of the upper support plate 3, a second clamp 6 is arranged on the side of the lower support plate 4 close to the first clamp 5, a second telescopic rod 19 is installed on the outer wall of the first clamp 5 away from the spring 8, and the other end of the second telescopic rod 19 is connected to the outer wall of the upper support plate 3.
[0026] In this embodiment, the outer wall of the upper support plate 3 is provided with positioning holes 13 at equal intervals. The positioning holes 13 penetrate the outer wall of the fixture body 1 , and positioning pins 18 are movably installed on the inner wall of the positioning holes 13 .
[0027] In this embodiment, a clamping groove 14 is provided on the outer wall of the first clamp 5 close to the active cavity 9 , and the width of the clamping groove 14 is the same as that of the transmission block 11 .
[0028] In this embodiment, a slide groove 2 is provided on the side wall of the upper support plate 3 , and a rocker 12 is welded to the outer wall of the turntable 15 , and one end of the rocker 12 passes through the slide groove 2 to the outer wall of the upper support plate 3 .
[0029] Specific as Figure 1 , Figure 4 and Figure 5 As shown, when using this structure, the protective tube is inserted from the center position of the clamp body 1 so that it is located at the center position of the first clamp 5 and the second clamp 6, and the rocker 12 is manually pulled downward to rotate. The rotation of the rocker 12 drives the transmission block 11 to rotate, so that the transmission block 11 rotates to the slot 14 to squeeze the first clamp 5. Due to the limiting effect of the limiting slot 16 and the limiting block 17 on the first clamp 5, the first clamp 5 moves along the first telescopic rod 7 to one side of the second clamp 6, and forms a clamping structure with the second clamp 6 to fix the protective tube, and the positioning pin 18 is inserted into the positioning hole 13. The rocker 12 is limited by the positioning pin 18 to prevent it from resetting, thereby keeping the clamping structure stable.
[0030] Embodiment 2: A spring 8 is installed on the outer wall of the first telescopic rod 7 , and one end of the spring 8 away from the lower support plate 4 is welded to the outer wall of the first fixture 5 .
[0031] In this embodiment, the first clamp 5 and the second clamp 6 are arc-shaped, and rubber rings are arranged on the outer walls of the first clamp 5 and the second clamp 6 at equal intervals.
[0032] In this embodiment, the cross section of the fixture body 1 is rectangular, and a rectangular through hole is provided at the center of the fixture body 1 .
[0033] In this embodiment, the outer walls of both sides of the fixture body 1 are provided with limiting grooves 16, and the first fixture 5 is symmetrically installed with limiting blocks 17 on the outer wall of one side of the fixture body 1, and the limiting grooves 16 and the limiting blocks 17 match each other.
[0034] Specific as Figure 1 , Figure 2 and Figure 3As shown, when the structure is used, when the first clamp 5 and the second clamp 6 clamp the protective tube, the protective tube will vibrate due to external influences and the pressure generated by the inner wall of the protective tube. The telescopic property of the first telescopic rod 7 and the elastic force of the spring 8 enable the protective tube to have a shock-absorbing effect during the clamping. At the same time, the arc-shaped rubber rings arranged on the outer walls of the first clamp 5 and the second clamp 6 can protect the outer wall of the protective tube during the clamping and shock-absorbing process to avoid damage to the outer wall of the protective tube due to vibration.
[0035] Working principle: When fixing the protective tube, one end of the protective tube is inserted into the rectangular through hole of the fixture body 1 so that its outer wall is located at the center of the first fixture 5 and the second fixture 6. The rocker 12 is manually pulled to drive the turntable 15 to rotate, and the turntable 15 is used to drive the transmission block 11 to rotate, so that the outer wall of the transmission block 11 touches the groove 14 set on the outer wall of the first fixture 5. Due to the limiting effect of the limiting groove 16 and the limiting block 17 on the first fixture 5, the first fixture 5 moves laterally along the trajectory of the limiting groove 16 in the direction of the second fixture 6. When the first fixture 5 moves, the second telescopic rod 19 is stretched and the first telescopic rod 7 is compressed, so that the first fixture 5 and the second fixture 6 are moved. The spacing is reduced to clamp the outer walls of both sides of the protective tube, and the positioning pin 18 is inserted into the position of the fixed rocker 12 through the positioning hole 13 to prevent the rocker 12 from resetting. At the same time, when the protective tube is fixed, the protective tube will vibrate due to the influence of the external environment and the pressure of the inner wall of the pipeline. The spring 8 is compressed on both sides of the first clamp 5 to cause the spring 8 to deform and generate elastic force. The vibration is reduced by the elasticity of the first telescopic rod 7 and the second telescopic rod 19 and the elastic force of the spring 8. At the same time, the arc-shaped rubber rings arranged on the outer walls of the first clamp 5 and the second clamp 6 will protect the outer wall of the protective tube. This structure is not only simple in structure and convenient for clamping and fixing the protective tube, but also can reduce the wear of the protective tube caused by vibration.
[0036] The above are only preferred embodiments of the present invention and are not intended to limit the present invention. Any modifications, equivalent substitutions, improvements, etc. made within the spirit and principles of the present invention should be included in the protection scope of the present invention.
