[0028] As shown in the figure, Figure 2 and Figure 4 The sliding hoisting mechanism 400 includes a sliding rail 410, a sliding frame 420, a chain 430, a speed reducer assembly 440, and a hoist assembly 450, and the details are as follows:

[0029] The sliding rail 410 can be arranged on the upper frame 110 of the frame assembly 100 by welding, and the number of sliding rails 410 is two, and the two sliding rails 410 are arranged side by side on the upper frame 110 in the horizontal direction, and the sliding frame 420 is movably arranged on the sliding rail 410, and the movable direction of the sliding frame 420 is parallel to the length direction of the sliding rail 410.

[0030] As shown in the figure, Figure 2 and Figure 4As shown, in the embodiment, the slide rail 410 is provided with a roller groove 411, the length direction of the roller groove 411 is consistent with the length direction of the slide rail 410, the slide frame 420 is provided with a plurality of roller pairs 421, the roller pairs 421 are rollably arranged in the roller groove 411, and then the movement of the slide frame 420 relative to the slide rail 410 can be realized.

The slide rail 410 is provided with two roller grooves 411 arranged side by side, and the rollers rotatably arranged on the slide frame 420 are arranged in the roller grooves 411 of the slide rail 410. Specifically, the rollers located on the left side of the slide rail 410 are arranged in one roller groove 411, and the rollers located on the right side of the slide rail 410 are arranged in the other roller groove 411. As can be seen from the figure, four roller pairs 421 are provided in the embodiment, a total of sixteen rollers, and two slide rails 410, each of which is connected with eight rollers, four on the left side of the slide rail 410 and four on the right side of the slide rail 410.

[0031] As Figure 2 As shown, in some preferred embodiments, the upper frame 110 of the frame assembly 100 is provided with at least two stop blocks 111, and the at least two stop blocks 111 are arranged on both sides of the slide rail 410 in the length direction of the slide rail 410. When the slide frame 420 moves to the limit position, the stop block 111 can abut against the slide frame 420, thereby limiting the movement of the slide frame 420 and playing a limiting role.

[0032] In some preferred embodiments, the stop block 111 is provided with a travel switch (not indicated), which is used to monitor the sliding travel of the slide frame 420. The travel switch can be directly or indirectly electrically connected with the speed reducer assembly 440. When the travel switch senses that the slide frame 420 is about to approach the threshold position, the travel switch can directly or indirectly transmit a signal to the speed reducer assembly 440, so as to control the slide frame 420 to stop moving, thereby ensuring the safety of the overall structure.

[0033] As Figure 2As shown, two chain fixing supports are arranged at the two ends of the upper frame 110 respectively, and the two chain fixing supports are fixed on the upper frame 110 along the length direction of the slide rail 410, and the two ends of the chain 430 are fixedly connected with the two chain fixing supports respectively, and the length direction of the chain 430 is parallel to the length direction of the slide rail 410. Among them, the chain 430 is arranged through the sliding frame 420 along the length direction of the slide rail 410, which can ensure the stability of the sliding frame 420.

[0034] As shown in the figure, Figure 4 The reducer assembly 440 is fixedly arranged on the sliding frame 420, and the output end (gear) of the reducer assembly 440 is engaged with the chain 430. When the reducer assembly 440 works, the sliding frame 420 can move transversely along the length direction of the chain 430. In this embodiment, the reducer assembly 440 is configured as a reducer with a brake, which can ensure uniform speed during sliding and prevent the arch block 500 from shaking.

[0035] As shown in the figure, Figure 4 The hoist assembly 450 is arranged on the sliding frame 420, and the hoist assembly 450 is used for hoisting the arch block 500. The number of the hoist assembly 450 is multiple, and four hoist assemblies 450 are shown in this embodiment. The four hoist assemblies 450 can provide multiple hoisting point positions to ensure the stability of the arch block 500 during hoisting. The hoist assembly 450 includes a hoist 451 and a hook 452. The hoist 451 is arranged on the sliding frame 420, the hoist chain of the hoist 451 is connected with the hook 452, and the hook 452 is connected with the lifting rod on the top of the arch block 500. In this embodiment, the hoisting structure (i.e. the hoist assembly 450) is integrated on the transport device, which can save the time for transferring the arch block 500 from the external vehicle to the transport device, and can reduce the floor area and realize integration.

[0036] In this embodiment, the hoist 451 can realize large weight and large load hoisting, the hook 452 adopts spherical forging design, and is tightly engaged with the lifting rod on the top of the arch block 500 to prevent unhooking during hoisting. It has large load capacity, fast and safe and reliable installation.

[0037] One working principle of the arch block transport device of this embodiment is as follows:

[0038] The external vehicle transports the inverted arch block 500 to the designated position, and then the transport device of the present embodiment drives the walking mechanism 200 to walk to the vicinity of the external vehicle through the walking reduction mechanism. Then, the four telescopic legs 300 are first raised to make the front wheels 210 and the rear wheels 220 of the transport device leave the ground by a certain height, and the transport device is basically in a horizontal state. Then, the multiple lifting hooks 452 are fixed to the lifting rods on the top of the inverted arch block 500. The oil pump is used to drive the hoist 451 to slowly lift the inverted arch block 500 through the lifting chain, so that the inverted arch block 500 leaves the vehicle chassis by a certain height. Then, the vehicle drives away, the telescopic legs 300 are retracted, and the walking reduction mechanism starts to walk to the predetermined position.

[0039] If it is necessary to lower the inverted arch block 500, the telescopic legs 300 are extended, the output end of the reduction mechanism assembly 440 is engaged with the chain 430 to drive the sliding frame 420 and the inverted arch block 500 to move horizontally to a certain position. In this process, the stop block 111 can limit the movement stroke of the sliding frame 420, and the travel switch monitors the displacement stroke. When the inverted arch block 500 moves to a certain position, the reduction mechanism assembly 440 stops working. At this time, the hoist 451 starts to work to slowly lower the inverted arch block 500, and the transport work is completed.

[0040] The above is only a specific implementation of the present application, and those skilled in the art can clearly understand that, for the convenience and brevity of description, the specific working process of the above-described system, module and unit can refer to the corresponding process in the foregoing method embodiments, which will not be described here. It should be understood that the protection scope of the present application is not limited to this. Any person skilled in the art can easily think of various equivalent modifications or replacements within the technical range disclosed in the present application, and these modifications or replacements should be covered within the protection scope of the present application.
