Embodiment two:
on the basis of the first embodiment, as shown in fig. 1, 3, 4, 5, 6, 8, 9, 10, 11 and 12, the upper inclined blocks 403 in the linkage stabilizing component 4 are fixedly connected to the bottom ends of the rear mounting plates 203, the left and right ends of the stabilizing base 401 are fixedly connected to the rear ends of the two groups of bottom mounting plates 103 respectively, the main surface of the stabilizing base 401 is uniformly provided with a plurality of groups of upright pole sliding holes 402, the upper inclined blocks 403 with the bottom inclined forward and upward and the left and right sides inclined forward are fixedly connected to the middle position of the bottom ends of the rear mounting plates 203, the main bodies of the lower inclined blocks 404 with the top inclined backward and downward are provided with upright pole insertion holes 405 with fan-shaped structures at positions coaxial up and down with each group of upright pole sliding holes 402, the bottom of every group pole setting 406 is coaxial fixedly connected with lower limit circle 407, the bottom of every group lower limit circle 407 is all fixedly connected with has downward sharp angle structure's spliced pole 408, the pole setting slide hole 402 of array pole setting 406 from coaxial distribution in proper order upwards slides with pole setting jack 405, and the lower limit circle 407 of array is located firm base 401 bottom surface below, still cup joint outer top spring 410 in every group pole setting 406, the top joint of outer top spring 410 is fixed in the bottom surface of lower sloping block 404, the bottom joint of outer top spring 410 is fixed at the top surface of firm base 401, the bottom fixed connection of interior connecting spring 409 is at the top surface of lower limit circle 407, and the external diameter of interior connecting spring 409 is less than the aperture of pole setting 406, and the elasticity of interior connecting spring 409 is greater than the elasticity of outer top spring 410 far away.
Two groups of side guide plates 603 in the side guide assembly 6 are symmetrically fixed at the position where the top surface of the stable base 401 and the lower inclined block 404 do not interfere, inclined surfaces on the left side and the right side of the upper inclined block 403 are matched with side inclined blocks 601 in a sliding manner, the rear side of each group of side inclined blocks 601 is uniformly and transversely connected with a plurality of groups of side guide posts 602, the inner side surface of each side guide plate 603 is uniformly and transversely fixed with a plurality of groups of side sliding seats 604, each group of side guide posts 602 are respectively and slidably inserted to one side facing the side guide plate 603 from the corresponding side sliding seat 604, the outer end of each group of side guide posts 602 is connected with a side connecting spring 605, the outer end of each group of side connecting springs 605 is fixedly connected with a side connecting seat 606, and each group of side connecting seats 606 are fixedly connected to the inner side surface of the side guide plate 603.

And the plurality of groups of upright rods 406 which are inserted into the upright rod insertion holes 405 in a sliding way are also connected in upright rod sliding holes 402 formed in the main body of the stable base 401 in a sliding way, and the bottom surface of the lower inclined block 404 is fixedly connected with a lower limit ring 407 at the bottom end of the upright rods 406 through an inner connecting spring 409.
The upper sloping block 403 then moves up and down along the mounting plate 203, which drives the lower sloping block 404 and the upright 406, the larger the distance that the upper sloping block 403 then moves forward along the mounting plate 203, the larger the distance that the lower sloping block 404 moves downward along the upright 406, when the plunger 408 contacts with the operation surface, the downward movement of the lower sloping block 404 will be transferred to the plunger 408 through the inner connecting spring 409, so as to form gradually linearly increasing pressure on the plunger 408, and the larger the distance that the rear mounting plate 203 extends forward along the width of the rear mounting plate 203, the larger the pressure on the mounting surface by the plunger 408, that is, the farther the distance that the front mounting plate 205 extends relative to the main mounting plate 101, the larger the reverse supporting force from the mounting surface received by the rear mounting plate 203, thereby solving the problems that the extending distance of the front mounting plate 205 is too long and the support of the rear rotary cylinder 208 is unstable during the shipping process.
After the support of the mounting surface by the back-rotation cylinder 208 is completed, the back-rotation cylinder 208 in the back mounting plate 203 can be more stable in the process of carrying and rotating; and since the hooks 214 hung on the front lower ends of the wire ropes 213 themselves have a certain weight, the wire ropes 213 wound in the front rotating cylinder 212 and the rear rotating cylinder 208 do not have a rope disorder.
Meanwhile, the upper inclined block 403 can further drive the two groups of side inclined blocks 601 to synchronously move inwards and outwards in opposite directions through the inclined planes on the left side and the right side after the transverse forward and backward movement of the mounting plate 203, and the upper inclined block 403 can be guided in the transverse forward and backward movement process through the real-time elastic sliding fit between the two groups of elastically connected side inclined blocks 601 and the inclined planes on the left side and the right side of the upper inclined block 403.
And similarly, the distance that the upper inclined block 403 moves forward is also large, the larger the distance that the two sets of side inclined blocks 601 move outward is, the larger the elastic deformation of the side connecting springs 605 connected between the side guide posts 602 and the side guide plates 603 is, so that the larger the reverse supporting force of the side connecting springs 605 on the side guide plates 603 and the side inclined blocks 601 and the upper inclined block 403 is, the larger the distance that the upper inclined block 403 extends forward from the mounting plate 203 is, the larger the elastic extrusion force of the side inclined blocks 601 on the left side and the right side of the upper inclined block 403 is, and the stability of the rear rotary drum 208 in the transportation process can be improved again by matching with the linkage stabilizing assembly 4.
Then, the building material is hung in the hanging hook 214, the control box 5 starts the rotating motor 209 to drive the back rotating cylinder 208 to rotate, so that the steel cable 213 is driven to form a winding action on the outer wall of the back rotating cylinder 208, and meanwhile, the steel cable 213 forms a winding action on the outer wall of the front rotating cylinder 212, so that the building material hung in the hanging hook 214 can be stably carried.
