[0024] like Figures 1 to 3 As shown, this embodiment provides a crane-type rail trolley, including a left base 1, a right base 2, wheel seats 3, and bottom wheels 4. A connecting frame 11 is provided on the left base 1, and a mounting frame 21 is provided on the right base 2. The left base 1 and the right base 2 are combined to form a trolley base. The connecting frame 11 is embedded in the mounting frame 21 to adjust the length of the trolley base, and the connecting frame 11 is restricted from detaching from the mounting frame 21 by a limiting member 5. Wheel seats 3 are provided at the bottom of both the left base 1 and the right base 2, and rotatable bottom wheels 4 are installed on the wheel seats 3. Extension arms 6 are also provided at the side ends of the left base 1 and the right base 2. Support members 61 are installed on the extension arms 6, and buffer members 62 are attached to the support members 61.

[0025] The connecting bracket 11 on the left base 1 can be equipped with at least two connecting rods 73, and the mounting brackets 21 on the right base 2 are equipped with a corresponding number of mounting brackets. Two extension arms 6 are provided on the side end of the left base 1, each extension arm 6 is equipped with an adjustable support 61, and a buffer 62 is provided on the support 61 for support and cushioning. The length of the trolley base formed by the combination of the left base 1 and the right base 2 can be adjusted by the overlap length of the connecting bracket 11 and the mounting bracket 21, indirectly adjusting the overall length of the trolley base. Several hole structures 8 for connecting with the limiting members 5 are provided on the connecting bracket 11 and the mounting bracket 21.

[0026] Furthermore, multiple extension arms 6 are provided, and the extension arms 6 are nested into the side openings of the left base 1 and the right base 2. The extension arms 6 are connected to the left base 1 and the right base 2 through limiting members 5.

[0027] Furthermore, the limiting component 5 is a screw.

[0028] Furthermore, the buffer 62 is a rubber pad.

[0029] Furthermore, the support member 61 includes a threaded rod 611 and a support plate 612. The threaded rod 611 is welded to the support plate 612, and the threaded rod 611 is threadedly connected to the extension arm 6. In use, the support height of the support plate 612 can be adjusted by rotating it.

[0030] Furthermore, the bottom of the right base 2 is provided with several mounting holes 211 and connecting holes 212. An auxiliary component 7 is installed on the mounting hole 211. The auxiliary component 7 can perform double limiting and cooperate with the limiting component 5 to prevent the connecting frame 11 from separating from the mounting frame 21.

[0031] Furthermore, a locking component 111 is installed on the right side of the connecting frame 11 via a hinge rod. The locking component 111 has a groove 112 and a first oblique opening 113 on its side. The groove 112 engages with the locking head 722 at the top of the locking post 72. Alternatively, the locking component 111 can be installed without a hinge rod.

After the engaging column 72 is installed in place, its left end is in contact with the limiting rod 77. The engaging column 72 can only rotate to the right with the rod body 73 as the rotation base point on the mounting base 71. Since the engaging column 72 and the mounting base 71 are locked on the mounting frame 21 by the reinforcing piece 75 and the connecting rod 76, after the engaging component 111 and the engaging column 72 are engaged, the limiting rod 77 restricts the connecting frame 11 from moving to the left, that is, it prevents the connecting frame 11 from separating from the mounting frame 21.

[0034] Furthermore, a locking head 722 is provided at the top of the locking post 72, and a second oblique opening 723 is provided at the side end of the locking head 722.

[0035] In use, the overall length of the crane rail trolley can be adjusted by adjusting the connection frame 11 and the mounting frame 21, and the overall length of the crane rail trolley can be adjusted by adjusting the extension length of the extension arm 6.
