[0025] The utility model will be further described below in combination with the drawings and embodiments.

[0026] First embodiment

[0027] Please see Figure 1 , Figure 2 , Figure 3 Among them, Figure 1 a structure schematic view of a first embodiment of the adjustable and lockable track fixing device provided by the utility model; Figure 2 for Figure 1 a structure schematic view of the upper cover plate from another perspective; Figure 3 for Figure 1 the bottom base from another perspective. An adjustable and lockable track fixing device comprises an upper cover plate 1, the bottom of the upper cover plate 1 is provided with a recess 14, the top of the recess 14 is provided with an adjusting groove 13, the top of the recess 14 is also provided with a mounting groove 11, and the top of the mounting groove 11 is provided with a through groove 12.

[0028] A base 2 is arranged at the bottom of the upper cover plate 1, the inside of the base 2 is provided with an open slot 22, and the top of the base 2 is fixedly connected with a wedge block 21.

[0029] A bucket bolt 3 is arranged, the screw cap of the bucket bolt 3 is clamped to the inner side of the open slot 22, the screw rod of the bucket bolt 3 is arranged on the inner side of the through groove 12, the outer side of the screw rod of the bucket bolt 3 is provided with a lock washer 31, and the outer side of the screw rod of the bucket bolt 3 is also threadedly connected with a nut 32.

[0030] When the upper cover plate 1 is sliding, the wedge block 21 slides on the inner side of the adjusting groove 12.

[0031] The through slot 12 is elongated, which makes it convenient for the user to adjust the position of the upper cover 1.

[0032] The wedge 21 is disposed on the inner side of the adjustment groove 13, and the wedge 21 and the adjustment groove 13 are adapted to each other.

[0033] The bottom of the anti-loosening gasket 31 abuts against the top of the upper cover plate 1.

[0034] Anti-loosening washer 31 is a mechanical part used in mechanical connections to prevent fasteners such as bolts and nuts from loosening. It is usually installed between the bolt head or nut and the connected parts. By providing additional friction or other anti-loosening mechanisms, it ensures that the fasteners can remain tight under the action of external forces such as vibration and impact, thereby ensuring the safety and stability of mechanical equipment.

[0035] The bottom of the nut 32 abuts against the top of the anti-loosening washer 31.

[0036] The internal threads of nut 32 are compatible with the external threads of bucket bolt 3.

[0037] One side of the base 2 is attached to one side of the inner side of the groove 14.

[0038] The working principle of the adjustable and lockable track fixing device provided by this utility model is as follows:

[0039] During installation, the base 2 is welded to both sides of the track on the track beam to ensure that the base is installed firmly and in the correct position. Then, the nut of the bucket bolt 3 is moved to the inner side of the opening slot 22 until the nut of the bucket bolt 3 and the opening slot 22 are engaged. Then, the upper cover plate 1 is placed on top of the base 2, and the top of the bucket bolt 3 passes through the through slot 12. At the same time, the wedge 21 is engaged with the inner side of the adjusting slot 13. Then, the anti-loosening washer 31 is placed on the outer side of the bucket bolt 3. Then, the nut 32 is threaded onto the outer side of the bucket bolt 3. The user can then move the upper cover plate 1 to adjust the position of the screen plate 1. At this time, the bucket bolt 3 will slide on the inner side of the through slot 12, and the wedge 21 will slide on the inner side of the adjusting slot 13. Then, the nut 32 is rotated again to make the anti-loosening washer 31 press against the top of the upper cover plate 1.

[0040] Compared with related technologies, the adjustable and lockable track fixing device provided by this utility model has the following advantages:

[0041] The upper cover plate 1, base 2, bucket bolt 3, and nut 32 work together to form a cohesive structure. During installation, simply insert a single bucket bolt 3 into the inner side of the opening slot 22, then place the upper cover plate 1 on top of the base 2, ensuring the top of the bucket bolt 3 passes through the through slot 12. Finally, place a single anti-loosening washer 31 and nut 32 on the outer side of the bucket bolt 3. Compared to traditional rail clamps with separate adjusting pins, this reduces damage to the base shoulder caused by the adjusting pin under stress and prevents the adjusting pin from automatically dislodging. It also significantly shortens installation and disassembly time. This not only improves the working performance of the rail clamp and reduces the frequency of rail clamp maintenance during crane use, but also increases construction efficiency and reduces labor costs.

[0042] The working principle of the adjustable and lockable track fixing device provided by this utility model is as follows:

[0043] When in use, after the operator moves the upper cover plate 1 to the appropriate position, the upper cover plate 1 is moved downward, so that the wedge strip 4 can be inserted into the inner side of the wedge groove 5, which can limit the movement between the upper cover plate 1 and the base 2.

[0044] Compared with related technologies, the adjustable and lockable track fixing device provided by this utility model has the following advantages:

[0045] By using wedge-shaped strips 4 and wedge-shaped grooves 5 in combination, after the base 2 and the upper cover plate 1 are installed, the upper cover plate 1 and the base 2 can be limited to prevent movement and increase the stability after installation.

[0046] The above description is merely an embodiment of this utility model and does not limit the patent scope of this utility model. Any equivalent structural or procedural transformations made based on the content of this utility model specification and drawings, or direct or indirect applications in other related technical fields, are similarly included within the patent protection scope of this utility model.
