[0030] The improved small prefabricated component handling device comprises: a trolley 1;

[0031] A mounting frame 2, the bottom of which is fixed to the top of the trolley 1, and a connecting rope 3 is provided at the bottom of the mounting frame 2;

[0032] A clamping jaw assembly 4, which is arranged at the bottom end of the connecting rope 3, and includes a supporting plate 41, two mounting blocks 42, two rotating shafts 411, two clamping plates 43, two first inclined blocks 44, two second inclined blocks 45, a mounting seat 46, a sliding block 47, two fixing plates 48, two round protrusions 49, two limiting structures 412, two friction sleeves 413 and a hanger 410;

[0033] The two mounting blocks 42 are respectively fixedly connected to the two sides of the support plate 41, the two rotating shafts 411 are respectively rotatably connected to the two mounting blocks 42, the two clamping plates 43 are respectively fixed to the two rotating shafts 411, the two first inclined blocks 44 are respectively fixedly connected to the two clamping plates 43, the two second inclined blocks 45 are respectively fixedly connected to the two clamping plates 43, the mounting seat 46 is fixedly connected to the top of the support plate 41, the sliding block 47 is slidably connected to the inside of the mounting seat 46, the two fixed plates 48 are respectively fixedly connected to the two sides of the sliding block 47, the two round protrusions 49 are respectively fixedly connected to the front of the two fixed plates 48, the two limiting structures 412 are both installed on the front of the support plate 41, and are respectively located on one side of the two rotating shafts 411, the two friction sleeves 413 are respectively fixed to the two rotating shafts 411, the hanger 410 is fixedly connected to the top of the sliding block 47, and the hanger 410 is arranged at the bottom end of the connecting rope 3;

[0034] The first inclined block 44 is located on the top of the second inclined block 45 , and the round protrusion 49 is located between the first inclined block 44 and the second inclined block 45 .

[0035] The length of the connecting rope 3 can be selected according to actual needs, and the weight of the sliding block 47 can be selected according to actual needs to ensure that it can fall stably by its own gravity.

[0036] The distance between the first inclined block 44 and the second inclined block 45 is 1.1-1.5 times the diameter of the round protrusion 49, which ensures that the round protrusion 49 has sufficient movement space in the middle and is not prone to getting stuck.

[0037] The limiting structure 412 includes a fixing block 4121, a fastening bolt 4122 and a friction block 4123. The fixing block 4121 is fixed on the support plate 41. The fastening bolt 4122 passes through the fixing block 4121 and is threadedly connected to the fixing block 4121. The friction block 4123 is rotatably connected to one end of the fastening bolt 4122.

[0038] By manually rotating the fastening bolt 4122 , the friction block 4123 can be moved toward the friction sleeve 413 until the two are in contact, thereby limiting the rotation shaft 411 , fixing the rotation shaft and preventing it from rotating, thereby ensuring the stability of the clamping of the clamping plate 43 .

[0039] Preferably, the friction block 4123 can be slidably connected to the support plate 41 .

[0041] Push rods 5 are fixedly connected to the front and rear sides of the left side of the trolley 1.

[0042] The working principle of the improved small prefabricated component handling device provided by the utility model is as follows:

[0043] When in use, the support plate 41 is firstly set on the top of the prefabricated component, and the two clamping plates 43 are on both sides of the prefabricated component. Then, the right side of the trolley is tilted upward, so that the mounting frame 2 is tilted upward, driving the connecting rope 3 to be pulled upward and tightened. At this time, the hanger 410 will move upward, so that the sliding block 47 moves upward, driving the fixing plates 48 on both sides to move upward, and then the two round protrusions 49 are lifted upward, providing an upward thrust to the two first inclined blocks 44, and the clamping plate 43 is rotatably connected to the mounting block 42, so that the first inclined block 44 will not move upward but swing to one side in an arc shape, so that the clamping plate 43 clamps the prefabricated component and then carries it;

[0044] Similarly, after the transportation is completed, the right side of the trolley falls, causing the connecting rope 3 to loosen. At this time, the sliding block 47 falls due to gravity, causing the fixed plate 48 to move downward, thereby causing the round protrusion 49 to slide downward, providing a downward thrust to each second inclined block 45 next year, thereby causing the clamping plate 43 to swing in the opposite direction to loosen the prefabricated component.

[0045] Compared with the related art, the improved small prefabricated component handling device provided by the utility model has the following beneficial effects:

[0046] By tilting the right side of the trolley upward, the mounting frame 2 is tilted upward, driving the connecting rope 3 to be pulled upward and tightened. At this time, the hanger 410 will move upward, causing the sliding block 47 to move upward, driving the fixed plates 48 on both sides to move upward, and then causing the two round protrusions 49 to lift upward, providing an upward thrust to the two first inclined blocks 44, and the clamping plate 43 is rotatably connected to the mounting block 42, so that the first inclined block 44 will not move upward but swing to one side in an arc shape, so that the clamping plate 43 clamps the prefabricated component and then carries it. The operation is convenient and quick, which can facilitate the staff to carry it and improve the carrying efficiency. The clamping force of the clamping plate 43 increases with the increase of the gravity of the prefabricated component. The heavier the prefabricated component, the higher the clamping force, and the more stable it is to use.

[0050] The convex tooth structure 6 can improve the clamping stability of the clamping plate 43, the bottom bracket 7 can support the prefabricated component, and the triangular inclined surface structure can facilitate the bottom bracket 7 to be inserted into the bottom of the prefabricated component.

[0051] The device further comprises four support frames 8 , and the support frames 8 are installed on the support plate 41 .

At this time, the support frame 8 can be taken out from the front to the front, so that the plug-in block 11 is separated from the latch 10, and the support frame 8 can be completely disassembled. Similarly, the installation can be completed by reversing the steps.

[0054] The plug block 11 is provided with a plug hole matched with the plug pin 10 .

[0055] Compared with the related art, the improved small prefabricated component handling device provided by the utility model has the following beneficial effects:

[0056] The provision of the convex tooth structure 6 can increase the clamping force with the prefabricated component, and the provision of the bottom support 7 can support the bottom of the prefabricated component to prevent it from slipping during transportation.
