A pulley frame and a working machine according to an embodiment of the present utility model are described below with reference to fig. 1 to 5. It should be understood that the following description is only illustrative of the embodiments of the utility model and is not intended to limit the utility model in any way.

An embodiment of the first aspect of the present utility model provides a pulley frame 700, as shown in fig. 1 to 5, which includes an auxiliary pulley frame 700, a base 900, and a main pulley frame 800. The auxiliary pulley frame 700 includes a first frame body 100 and a second frame body 200.

Wherein the first frame 100 is connected with the second frame 200. The first frame 100 is rotatable relative to the second frame 200 to switch between a folded position and an unfolded position. In the folded position, the first frame 100 is folded to one side of the second frame 200; in the unfolded position, the first frame 100 is unfolded to one end of the second frame 200.

In the pulley frame provided by the present utility model, the auxiliary pulley frame 700 includes the split type first and second frame bodies 100 and 200. One end of the first frame 100 is rotatably connected with one end of the second frame 200, so that the first frame 100 can be turned over relative to the second frame 200 and converted between a folded position and an unfolded position. When the working machine is required to perform the work, the first frame 100 is switched to the extended position, specifically, the first frame 100 is turned over and extended to the extension direction of the second frame 200, or the first frame 100 is turned over and extended to one end of the second frame 200. When the transfer work machine is required, the first frame 100 is converted to a folded position, specifically, the first frame 100 is turned over, folded and stored to one side of the second frame 200.

With this structural arrangement, the auxiliary pulley frame 700 is provided as a split structure including the first and second frame bodies 100 and 200, and allows the first frame body 100 to be rotatable with respect to the second frame body 200 to switch between the unfolded position and the folded position. When the construction work is required, the first frame body 100 is converted to the unfolded position to prevent interference with the power head when the auxiliary pulley frame 700 lowers the auxiliary materials. When it is desired to transport the work machine, the first frame 100 is converted to the collapsed position to reduce the transport height of the work machine. Further, the transportation difficulty is reduced, and the transportation cost is reduced.

In one embodiment of the present utility model, the first and second frames 100 and 200 are connected by a rotational connection.

The swivel connection comprises a first hinge body 302, a first hinge seat 301 and a connection pin 303. The first hinge body 302 is connected with the first frame body 100. The first hinge base 301 is connected to the second frame 200. A connecting pin 303 is inserted between the first hinge body 302 and the first hinge base 301.

For example, as shown in fig. 1 to 4, one end of the first frame 100 is a connection end, and one end of the second frame 200 is a connection mating end. The first hinge body 302 is connected to the first frame body 100 at a position near one side of the connection end in the folding direction of the first frame body 100. The first hinge base 301 is connected to the connection mating end of the second frame 200, and its size and installation position are adapted to those of the first hinge body 302. The first hinge base 301 is inserted into the first hinge body 302 and rotatably coupled thereto by a coupling pin 303. When the first frame 100 is in the folded position, a certain angle may be formed between the first frame 100 and the second frame 200, as shown in fig. 1 to 4. Alternatively, when the first frame 100 is in the folded position, the first frame 100 may be attached to and received in a side surface of the second frame 200, which is not shown in the drawings.

In one embodiment of the present utility model, the auxiliary pulley frame 700 further includes a first locking body 403.

The first locking body 403 is detachably connected between the first frame 100 and the second frame 200 to lock the first frame 100 in the unfolded position.

Further, in one embodiment of the present utility model, the first frame body 100 is provided with a second hinge body 402. The second frame 200 is provided with a second hinge seat 401. In the unfolded position, the first locking body 403 is connected between the second hinge body 402 and the second hinge seat 401.

For example, as shown in fig. 1 to 4, the second hinge body 402 is connected to the first frame body 100 at a position of one side of the connection end thereof, which is far from the folding direction of the first frame body 100. The second hinge seat 401 is connected to the connection mating end of the second frame 200, and its size and installation position are adapted to those of the second hinge body 402.

When construction work is required, as shown in fig. 1, the first frame 100 is turned to the unfolded position, the second hinge seat 401 is inserted into the second hinge body 402, and the first locking body 403 is inserted between the second hinge seat 401 and the second hinge body 402. Therefore, the first frame 100 is fixedly connected with the second frame 200, so that the first frame 100 is prevented from rotating during the construction operation, and the stability and safety of the construction operation are improved. When the work machine needs to be transported, the first locking body 403 is pulled out to restore the rotational displacement capability of the first frame 100. For example, the first locking body 403 includes a locking pin.

It should be noted here that the above-mentioned embodiment is only one embodiment of the present utility model, and should not be construed as limiting the present utility model in any way. For example, in other embodiments of the present utility model, the first locking body 403 may further include a locking hook. The first frame body 100 is provided with a shackle, and one end of the locking hook is connected with the second frame body 200. When the first frame 100 is shifted to the unfolded position, the other end of the locking hook can be hooked into the locking ring, so that the first frame 100 is fixedly connected with the second frame 200.

In one embodiment of the present utility model, the auxiliary pulley frame 700 further includes a second locking body 500.

The second locking body 500 is detachably connected between the first and second frames 100 and 200 to lock the first frame 100 in the folded position.

As shown in fig. 3, one end of the second locking body 500 is rotatably connected to the second hinge body 402, and the other end of the second locking body 500 is rotatably connected to the second hinge seat 401. For example, the second locking body 500 includes a connection rod. The connecting rod is a rod-shaped structure with a fixed length. Thereby, the connecting rod can lock and fix the first frame 100 in the folded position. The length of the connecting rod can be determined according to the folding requirement of the first frame 100.

Alternatively, the second locking body 500 may further include a telescopic rod. For example, as shown in fig. 4, the telescopic rod includes a hydraulic cylinder. One end of the hydraulic cylinder can be rotatably connected with the second hinge body 402, and the other end of the hydraulic cylinder can be rotatably connected with the second hinge seat 401.

When the first frame 100 needs to be switched to the extended position for operation, if a hydraulic cylinder is connected between the second hinge body 402 and the second hinge seat 401, the hydraulic cylinder has the function of locking the first frame 100 and enables the first frame 100 to be fixedly maintained in the extended position. Meanwhile, the center distance can be adjusted by adjusting the extension length of the piston rod of the hydraulic cylinder, so that the hoisting range is enlarged.

When the first frame 100 needs to be switched to the folded position, the hydraulic cylinder connected between the second hinge body 402 and the second hinge seat 401 also has the function of locking the first frame 100, so that the first frame 100 is fixedly maintained in the folded position. Meanwhile, the folding height of the first frame 100 can be adjusted by adjusting the extension length of the hydraulic cylinder piston rod, and further, the transport height of the working machine can be adjusted. In addition, the hydraulic cylinder can also provide a tilting driving force for the first frame body 100, so that the manual labor intensity can be reduced.

In still another embodiment of the present utility model, as shown in fig. 2, a third hinge base 601 is provided on the first frame 100. A fourth hinge seat 602 is provided on the second housing 200. In the folded position, one end of the second locking body 500 is connected to the third hinge seat 601, and the other end of the second locking body 500 is connected to the fourth hinge seat 602. When the second locking body 500 is a fixed-length connection rod, the first frame body 100 has a folded height. When the second locking body 500 is of a telescopic structure such as a hydraulic cylinder, the folding height of the first frame 100 can be flexibly adjusted.

In one embodiment of the present utility model, as shown in fig. 5, a main pulley frame 800 and an auxiliary pulley frame 700 are fixedly connected to a base 900, respectively. For example, main pulley frame 800 and auxiliary pulley frame 700 are welded to base 900, respectively.
