Description

[0001] The invention belongs to the technical field of rail clamps, and in particular relates to a rail clamp that can be quickly disassembled and assembled and a disassembly and assembly method. Background Art

[0002] At present, my country's artificial side-assembled platforms are mainly used to be erected on the side of railway flatbed cars to ensure that the equipment on the railway flatbed cars can be loaded and unloaded along the side platform passages. In order to meet the stability of the platform during loading and unloading tasks, track clamps are usually installed on the platform legs, and the track clamps are connected and locked to the rails to ensure the overall stability of the platform.

[0003] However, the rail clamps installed on the legs of the side-assembled platform are often welded to the legs and cannot be disassembled. When performing loading and unloading tasks, if the railway flatbed car needs to move forward or backward, the assembled platform needs to be dismantled and re-erected after the flatbed car moves into place to ensure the equipment loading and unloading tasks. There is a problem of repeated erection, high labor intensity, and low loading and unloading efficiency. Summary of the invention

[0061] The structure of the support rod assembly 2 in this embodiment can adjust the length of the support rod assembly 2 simply by screwing the sleeve 2.1, which is simple and quick.

[0062] See attached Figure 2 and 4The connecting crossbeam 1 is a square beam, and one end of the connecting crossbeam 1 connected to the leg 40 is provided with an ear plate III1.1, and two parallel pin holes I are provided on the ear plate III1.1. The leg 40 is provided with an ear plate corresponding to the ear plate III1.1, and two opposite pin holes are provided; the pin A passes through a pin hole I on the ear plate III1.1 and a corresponding pin hole on the leg 40, and is used as a hinge point to realize the rotation of the connecting crossbeam 1 relative to the leg 40; the locking member is a pin B, and the pin B can be detachably passed through another pin hole I and a corresponding pin hole on the leg 40. Specifically, the ear plate III1.1 is a single ear plate, and the ear plate on the leg 40 is a double ear plate;

[0063] Furthermore, the axes of the pin holes I and the pin holes on the legs 40 are all in the vertical direction, which facilitates the horizontal rotation of the connecting beam 1, which is safer and more labor-saving;

[0064] A blind hole is arranged at one end of the connecting beam 1 connected to the connecting rod. The connecting rod is a threaded rod 3.1. One end of the threaded rod 3.1 extends into the blind hole and is welded to the connecting beam 1. Figure 5 The locking assembly includes two locking nuts 3.2; the two locking nuts 3.2 are both threadedly connected to the connecting rod, and the two locking nuts 3.2 are respectively located on both sides of the rail clamping assembly 4; the rail clamping assembly 4 is clamped by screwing the locking nuts 3.2 to limit the rotation of the rail clamping assembly 4 relative to the connecting rod; the clamping of the rail clamping assembly 4 is released by screwing the locking nuts 3.2, and the right rail clamping plate 4.2 and the left rail clamping plate 4.1 of the rail clamping assembly 4 can be moved along the axial direction of the connecting rod to release the clamping connection between the rail clamping assembly 4 and the rail 300, thereby realizing the axial rotation of the rail clamping assembly 4 along the connecting rod.

[0065] See attached Figure 6 , the inner side of the rail clamping assembly 4 is between the right rail clamping plate 4.2 and the left rail clamping plate 4.1, and the inner sides of the left rail clamping plate 4.1 and the right rail clamping plate 4.2 are connected to the connecting rod at one end (i.e. the inner upper end of the left rail clamping plate 4.1 and the right rail clamping plate 4.2) and are provided with a top block, and the other end (the inner lower end) is provided with an inwardly bent hook for clamping with the rail 300;

[0066] The rail clamping assembly 4 also includes a fixing screw 4.3. The left rail clamping plate 4.1 is provided with more than one through hole, and the right rail clamping plate 4.2 is provided with threaded holes with the same number as the through holes. The through holes and the threaded holes are opposite to each other. The fixing screw 4.3 includes a screw head and a screw. The screw head is located outside the through hole.

[0071] Step 3: thread a locking nut 3.2 onto the connecting rod, put the rail clamping assembly 4 onto the connecting rod, and then thread another locking nut 3.2 onto the connecting rod;

[0072] Step 4: Pin the ear plate of the adjusting screw rod Ⅰ2.2 in the strut assembly 2 to the ear plate Ⅰ1.2 on the connecting beam 1, and pin the ear plate of the adjusting screw rod Ⅱ2.3 in the strut assembly 2 to the ear plate Ⅱ4.2.1 of the right track clamping plate 4.2.

[0073] Embodiment 2:

[0074] Based on Example 1, this embodiment provides a method for quickly disassembling and assembling a rail clamp, including: an installation method and a disassembly method;

[0075] The installation method is:

[0076] First, place the left rail clamping plate 4.1 on the left side of the rail 300 and the right rail clamping plate 4.2 on the right side of the rail 300, and install the locking piece to limit the rotation of the connecting beam 1 relative to the supporting leg 40;

[0077] Then, the locking assembly is used to lock the right rail clamping plate 4.2 and the left rail clamping plate 4.1, so that the bottoms of the right rail clamping plate 4.2 and the left rail clamping plate 4.1 are matched and clamped on the rail 300; specifically, the locking nuts 3.2 are rotated to lock the right rail clamping plate 4.2 and the left rail clamping plate 4.1;

[0078] Then, adjust the fixing screw 4.3 so that the screw head of the fixing screw 4.3 abuts against the left rail clamping plate 4.1, thereby reinforcing the connection between the right rail clamping plate 4.2 and the lower part of the left rail clamping plate 4.1 and the rail 300;

[0079] Finally, the length of the strut assembly 2 is shortened until the connecting beam 1 and the rail clamp assembly 4 are fastened to enhance the stability of the rail clamp 100. Specifically, the sleeve 2.1 is screwed to move the adjusting screw rod I2.2 and the adjusting screw rod I2.2 toward each other to shorten the length of the strut assembly 2.

[0080] The disassembly method is:

[0081] First, lengthen the support rod assembly 2 and release the fastening of the rail clamp assembly 4 and the connecting beam 1;

[0082] Then, loosen the set screw 4.3 to release the locking assembly from locking the right rail clamping plate 4.2 and the left rail clamping plate 4.1, so that the right rail clamping plate 4.2 and the left rail clamping plate 4.1 can move away from each other along the connecting rod and detach from the rail 300;

[0083] Then, the right rail clamping plate 4.2 and the left rail clamping plate 4.1 are rotated so that the right rail clamping plate 4.2 and the left rail clamping plate 4.1 rotate along the axis of the connecting rod, and the right rail clamping plate 4.2 and the left rail clamping plate 4.1 are both located above the rail 300;

[0084] Finally, the locking piece is removed, and the rail clamp 100 is lifted so that the rail clamp 100 as a whole rotates around the hinge point connecting the cross beam 1 and the support leg 40 , so that the rail clamp 100 is located outside the wheel of the railway flatbed car 200 .

[0085] For details, see the attached Figure 7 , lift the rail clamp 100 so that the rail clamp 100 as a whole rotates around the hinge point connecting the cross beam 1 and the support leg 40 by more than 100 degrees, which can be 105 degrees.

[0086] In summary, the above are only preferred embodiments of the present invention and are not intended to limit the protection scope of the present invention.
