[0034] The manual transport trailer 2 comprises a frame plate 21, both inner sides of the frame plate 21 are rotatably provided with a tooth chain 22, a plurality of roller units 23 are rotatably arranged on the frame plate 21, both sides of the roller units 23 are drivingly connected with the tooth chain 22, steel baffle plates 24 are fixedly arranged on the front and rear sides of the frame plate 21, locking pieces 25 are fixedly arranged on the steel baffle plates 24, positioning holes 251 are formed in the locking pieces 25, the T-shaped quick-release pin 3 can be arranged in the positioning holes 251, and a buffer baffle 26 is fixedly arranged at one end of the frame plate 21 away from the locking pieces 25.

[0035] It should be explained that the present application is applicable to various types of small and medium-sized prefabricated components with a width not greater than 1.2 m and a length not greater than 2 m.

[0036] Based on the above technical scheme, when the transport vehicle arrives to unload, the movable hook 15 is connected with the transport vehicle and the angle of the movable hook 15 is adjusted, the locking pin 14 is inserted to fix the conveying channel 11 with the transport vehicle, the height of the lifting adjustable support frame 12 is adjusted to determine the slope of the conveying channel 11, the operator moves the manual transport trailer 2, then aligns the pin hole with the positioning hole 251, and inserts the T-shaped quick-release pin 3 into the pin hole to fix the conveying device 1 and the manual transport trailer 2, releases the small and medium-sized prefabricated components, the prefabricated components move along the conveying channel 11 to the roller units 23, at the same time, the roller units 23 at the tail of the vehicle unload the impact force of the prefabricated components and transmit the impact force to the roller units 23 at the head of the vehicle through the tooth chain 22, and finally the prefabricated components are intercepted by the buffer baffle 26.

[0037] On the basis of the above technical scheme, the conveying device 1 and the manual transport trailer 2 are connected with the transport vehicle through the movable hook 15, which can effectively ensure the close fit of the device and the transport vehicle, and the adjustable support frame 12 is used to adjust the slope angle of the conveying channel 11, which ensures the safety and reliability of the conveying channel 11 during unloading; the tail of the manual transport trailer 2 is connected with the conveying device 1 through the T-shaped quick-release pin 3, the frame plate 21 is provided with the roller units 23, and the buffer baffle 26 is arranged at the head of the vehicle, the prefabricated components transmitted from the conveying device 1 are unloaded to the manual transport trailer 2 through the roller units 23, the roller units 23 cooperate with the tooth chain 22 to gradually buffer the stress of the prefabricated components transmitted from the conveying device 1 to the roller units 23 at the head of the vehicle, unload the impact force, and finally intercept the prefabricated components with large impact force through the buffer baffle 26, preventing the prefabricated components from directly rolling off the conveying belt to the ground and causing property loss and directly acting the impact force on the head of the manual transport trailer 2.

[0038] In a possible implementation, the lower ends of the adjustable support frames 12 are fixedly provided with anti-skid pads 13.

The rollers 231 at the axial outer sides of the bearings 232 are fixedly provided with locking teeth 234. The impact force generated by the prefabricated components transmitted from the conveying device 1 can directly act on the rubber layers 233. The rubber layers 233 have a certain deceleration effect on the prefabricated components. Meanwhile, the impact force is decomposed into horizontal forces, which move in the horizontal direction, so that the roller units 23 rotate.

[0043] In a possible implementation, the locking teeth 234 are in transmission connection with the tooth chains 22. That is, the impact force generated by the prefabricated components transmitted from the conveying device 1 directly acts on the rubber layers 233. The roller unit 23 at the tail rotates preferentially. The locking teeth 234 of the roller unit 23 also rotate preferentially, so that the tooth chains 22 rotate. The tooth chains 22 use the rotating force to drive the plurality of roller units 23 to rotate. That is, the roller unit 23 at the tail gradually buffers and unloads the stress to the roller unit 23 at the head.

[0044] In a possible implementation manner, the buffer baffle 26 comprises a base plate 261 fixedly arranged with the vehicle frame plate 21, and a plurality of rubber buffer pads 262 are uniformly fixedly arranged on the base plate 261, so that the prefabricated component with a large impact force is finally intercepted by the rubber buffer pad 262, thereby avoiding the prefabricated component from directly impacting on the base plate 261, and further protecting the prefabricated component from collision damage.

[0045] In a possible implementation manner, the rubber buffer pad 262 is arranged at an inclination angle of 45° with respect to the surface wall of the base plate 261, and the rubber buffer pad 262 is made of rubber material, and the rubber buffer pad 262 can intercept the prefabricated component after being angularly raised, thereby avoiding the prefabricated component from directly rolling off the manual transport trailer 2 and being damaged.

[0046] Working principle:

[0047] When the transport vehicle arrives to unload, the movable hook 15 is first connected with the transport vehicle and the angle of the movable hook 15 is adjusted, the locking pin 14 is inserted to fix the conveying channel 11 with the transport vehicle, the height of the lifting adjustable support frame 12 is adjusted to determine the slope of the conveying channel 11, the operator moves the manual transport trailer 2 through the handle frame 28, so that the vehicle frame plate 21 at the tail is arranged on the L-shaped connecting plate 16, then the pin hole is aligned with the positioning hole 251, the T-shaped quick release pin 3 is inserted into the pin hole to fix the conveying device 1 and the manual transport trailer 2, the small and medium-sized prefabricated components are released, the prefabricated components move along the conveying channel 11 to the roller unit 23, at the same time, the roller unit 23 at the tail unloads the impact force of the prefabricated components and transmits the impact force to the roller unit 23 at the head through the toothed chain 22, and finally the prefabricated components are intercepted by the buffer baffle 26.

[0048] The above embodiments are only used to illustrate the technical solutions of the present application, but not limit the present application. The present application is not limited to the exact structure described above and shown in the drawings, and the specific implementation of the present application should not be limited to the above description.
