Description

Technical Field

[0001] The utility model relates to the field of rail transportation, in particular to a rail switching device used for rigid landfill operations. Background Art

[0002] Existing equipment used in hazardous waste landfill operations typically consists of single- or multi-span cranes, which can only operate on designated tracks and cannot flexibly cross tracks. Crossing tracks requires the use of a crane to maneuver the entire crane from its original track to a designated one, a time-consuming, labor-intensive, and inefficient process.

[0003] At present, the transfer device for hazardous waste landfill operations places hazardous waste near the loading area on the transfer conveying platform. First, the conveying platform is connected through the hook on the crane. The crane is started to slowly raise the conveying platform with hazardous waste and the conveying platform until the conveying platform is completely off the ground. After confirming that the conveying platform has been lifted smoothly, the crane is operated to rotate the conveying platform 90 degrees along the cross-type track and then transfer it to the transfer track. When the crane approaches the transfer destination, the operator accurately controls the movement of the crane so that the conveying platform is accurately aligned with the unloading position, and then operates the lifting mechanism to slowly lower the conveying platform until it lands smoothly. However, in order to ensure that the hazardous waste does not fall during the entire transfer process, the crane needs to rotate smoothly, which slows down the crane, resulting in low efficiency in transferring the conveying platform, which cannot meet the operational needs;

[0004] Therefore, it is necessary to design a track switching device that improves the above problems. Summary of the Invention

When the track 9 enters the clamping slot, the track 9 is clamped between the inner wall of the clamping slot and the clamping block 7 through the rotation of the clamping block 7.

[0032] A clamping drive structure is installed at the bottom of the transfer conveying platform 8, one end of the clamping drive structure is connected to the bottom of the transfer conveying platform 8, and the other end of the clamping drive structure is rotatably connected to the part of the clamping block 7 away from the clamping rail 9. The clamping drive structure is used to drive the clamping block 7 to rotate.

[0033] The clamping drive structure includes a first drive structure 3 and a linkage rod structure installed at the driving end of the first drive structure 3. The first drive structure 3 is connected to the bottom of the transfer conveying platform 8. The first drive structure 3 drives the clamping block 7 to rotate through the linkage rod structure through telescopic movement.

[0034] The linkage rod structure includes a U-shaped connecting member 4, the open end of the U-shaped connecting member 4 is rotatably connected to one end of the rail clamping rod 5, and the end of the U-shaped connecting member 4 opposite to its open end is connected to the driving end of the first driving structure 3; the other end of the rail clamping rod 5 is rotatably connected to the clamping block 7.

[0035] The first driving structure 3 is an electric cylinder or an electric telescopic rod.

[0036] The clamping block 7 is provided with an arc-shaped surface facing the slot, which is in line with the outer shape of the track 9 .

[0037] The rotating device includes a steering drive structure 10 installed at the bottom of the transfer conveying platform 8, and a first bevel gear 11 is installed at the output end of the steering drive structure 10;

[0038] A second bevel gear 12 is sleeved and installed on the mounting portion of the rail wheel.

[0039] The steering drive structure 10 is a motor.

[0040] The lifting part 1 is an electric cylinder or an electric telescopic rod;

[0041] Transfer operation process: In the specific implementation, there are 4 rotating devices installed in the middle of the bottom of the transfer conveying platform, such as Figure 3 As shown, the multiple tracks are arranged in a cross shape. The tracks are installed on shims. A gap is set between the crosses to leave space for the rotating track wheels, so that the track wheels can rotate 90 degrees and contact the tracks to move normally. During the track switching, the third drive members of the four rotating devices are controlled by the control system to move synchronously. The lifting part 1 installed at the bottom of the transfer conveying platform is lowered to make the inner side of the claw 6 fit with the outer side of the track. Then, the first drive structure 3 controls the lifting of the U-shaped connector 4 and the track clamping rod 5. The U-shaped connector 4 drives the track clamping rod 5 to lift upward at the same time. The clamping block 7 at the end of the track clamping rod 5 tightens the claw 6, thereby firmly locking the transfer conveying platform to the outside of the track 9. Then, with the contact position between the clamping claw 6 and the track 9 as the support point, the lifting part 1 is lifted, and then the track wheel installed at the bottom of the entire transfer and conveying platform is lifted off the track 9. Finally, the third driving member installed on the platform track wheel drives the rotating device to rotate, and the track wheel installed at the bottom of the rotating device is rotated 90 degrees. After the track wheel rotates, it gradually descends through the lifting part 1, so that the track wheel and the transfer track are completely fitted. Finally, the first driving structure 3 drives the U-shaped connector 4 and the track clamping rod 5 to descend, and the U-shaped connector 4 drives the track clamping rod 5 to move downward. The clamping block 7 at the end of the track clamping rod 5 releases the track 9, and the clamping claw 6 is released at the same time. Then the lifting part 1 continues to drive the first telescopic rod 2 to lift the clamping part upward to the shortest state. Each track transfer operation takes about 5 minutes, which saves dozens of times of time and cost compared to the traditional crane that uses a crane to transfer the transfer and conveying platform.

[0042] It is worth noting that the present application is provided with a clamping part, a lifting part and a rotating device, and the clamping part is driven to move by the lifting part 1 so that the bottom of the clamping part is clamped on the outside of the track 9. The first driving structure in the clamping driving structure drives the clamping block to rotate through the linkage rod structure through telescopic movement. The track is clamped between the inner wall of the slot and the clamping block through the rotation of the clamping block. After the track 9 is clamped, the track wheel at the bottom of the transfer conveying platform 8 is moved away from the track 9 through the clamping part, and the rotating device drives the track wheel relative to the transfer conveying platform The transfer conveying platform is rotated so that the transfer conveying platform can be transferred to the transfer track. After the track wheel rotates, the clamping part descends to make the track wheel fit with the transfer track, so that the transfer conveying platform is transferred to the transfer track. The first driving structure is controlled to make the clamping block release the track and then the clamping part is lifted by the lifting part to complete the transfer conveying platform. Compared with the traditional crane that uses a crane to transfer the transfer conveying platform, the transfer conveying platform does not need to slow down during the transfer, and the transfer conveying platform is transferred, thereby saving dozens of times the transfer time and improving the transfer efficiency of the transfer conveying platform 8.
