Therefore, when transporting building materials, because building materials are generally heavy goods such as steel bars, plates and concrete, if they are transported only by manpower, a large amount of manpower is required, and the labor force of the staff is large. Therefore, lifting equipment is needed to quickly transport the materials and send the materials to different heights.
[0003] When existing hoisting equipment is in operation, if a section of the connecting rope breaks, the rope on the other side of the hoisted cargo will be quickly tightened and impacted, which may easily cause the cargo to swing to the other side or the connecting rope on the other side to break.

[0004] Base comprises support, castor, and frame upper is provided with guide rail, and support and conveyer frames movable end contact site are provided with recoil spring or rubber cushion, and castor is arranged on the pin of base bottom four, to carry mobile handler location.
[0005] The materials for road and bridge construction that need to be hoisted are connected through four connecting ends formed by two connecting ropes. A hook is fixed on the connecting end of the connecting rope to facilitate the connection between the connecting end of the connecting rope and the supporting device of the bridge construction materials;
[0006] After hoisting, the road and bridge construction materials drive the connecting seat to compress the second spring under the action of gravity, so that the prism approaches the push block, and the prism pushes the push block in contact to rotate outward;
[0007] If the connected end of the connecting rope breaks, the pressure on the corresponding side of the wheel mounting seat and the guide wheel installed on the wheel mounting seat will be reduced, so that the push block and the wheel mounting seat will be pushed to rotate outward under the action of the spring piece, so that the guide wheel is pressed against the corresponding rubber wheel, compressing the connecting rope, increasing the resistance to pulling the connecting rope, and thus slowing down the movement speed of the road and bridge construction materials and the side of the connecting rope that is not broken.
[0008] Furthermore, the circular seat is a hollow structure, lubricating oil is placed in the circular seat, the bottom end of the circular seat passes through the floating ship and contacts the seawater, the internal cavity of the turning platform base is connected to the circular seat, the lubricating oil circulates between the circular seat and the turning platform base, and power is provided by the oil pump.
[0009] Furthermore, a circular hole is opened in the middle of the connecting seat, a connecting rod is installed in the circular hole, and the bottom end of the connecting rod is connected to a prism, and the prism is used for limiting.
[0010] Furthermore, a cross groove is provided on the bottom surface of the connecting seat, and a wheel mounting seat is rotatably installed in the four notches of the cross groove. An opening is provided on the outer end of the wheel mounting seat, and strip grooves are provided on the opposite side surfaces of the opening.

The four notches of the cross groove are all installed with rubber wheels, and the rubber wheels are located on the outside of the wheel mounting seat. The push block rotating outward pushes the wheel mounting seat close to the rubber wheel.
[0012] Furthermore, a prism is fixed to the bottom end of the connecting rod, a second spring is sleeved on the outside of the connecting rod, the top end of the connecting rod extends to the other side through the circular hole, the installed second spring pushes the prism away from the connecting seat, and the outer side of the prism pushes the push block to rotate outward.
[0013] Furthermore, a spring piece is installed on the inner side of the push block, and the spring piece is a C-shaped structure. The push block and the prism are connected through the spring piece.
[0014] Furthermore, the two ends of the connecting rope pass through two guide wheels distributed along the same straight line. After the installed connecting rope passes through the two guide wheels distributed along the same straight line, and the two ends of the connecting rope are fixed with materials for road and bridge construction, the connecting rope pulls the turntable mounting seat to a vertical state, thereby facilitating the movement of the connecting rope along the guide wheel after lifting, thereby achieving the same force at both ends of the connecting rope, and a limiting groove is opened on the surface of the guide wheel to prevent the connecting rope from deviating on the guide wheel surface.

[0017] 2. The connecting rope installed in the present invention passes through two guide wheels distributed along the same straight line. After the materials for road and bridge construction are fixed at both ends of the connecting rope, the connecting rope pulls the turntable mounting seat to a vertical state, so that after lifting, the connecting rope moves along the guide wheel, thereby achieving the same force at both ends of the connecting rope, and a limiting groove is provided on the surface of the guide wheel to prevent the connecting rope from deviating on the guide wheel surface.

[0031] The road and bridge construction materials that need to be hoisted are connected through the four connecting ends formed by two connecting ropes 18. The connecting ends of the connecting ropes 18 are fixed with hooks to facilitate the connection of the connecting ends of the connecting ropes 18 with the supporting device of the bridge construction materials;
[0032] After hoisting, the road and bridge construction materials drive the connecting seat 10 to compress the second spring 19 under the action of gravity, so that the prism 12 approaches the push block 16, and the prism 12 pushes the push block 16 to rotate outward;
[0033] If the connected end of the connecting rope 18 breaks, the pressure on the corresponding side of the runner mounting seat 14 and the guide wheel 15 installed on the runner mounting seat 14 will be reduced, so that under the action of the spring piece 17, the push block 16 and the runner mounting seat 14 will be pushed to rotate outward, so that the guide wheel 15 is pressed against the corresponding rubber wheel 13, pressing the connecting rope 18, increasing the resistance to pulling the connecting rope 18, and thus slowing down the movement speed of the road and bridge construction materials and the side of the connecting rope 18 that is not broken.
[0034] The circular seat 4 is a hollow structure, and lubricating oil is placed inside the circular seat 4. The bottom end of the circular seat 4 passes through the floating ship 1 and contacts the seawater. The internal cavity of the turning platform base 5 is connected to the circular seat 4. The lubricating oil circulates between the circular seat 4 and the turning platform base 5, and power is provided by the oil pump.
[0035] A circular hole 1003 is provided in the middle of the connecting seat 10 , and a connecting rod 11 is fitted in the circular hole 1003 . The bottom end of the connecting rod 11 is connected to a prism 12 , which is used for positioning.
[0036] A cross groove 1001 is provided on the bottom surface of the connecting seat 10, and a rotating wheel mounting seat 14 is rotatably installed in the four notches of the cross groove 1001. An opening is provided at the outer end of the rotating wheel mounting seat 14, and strip grooves 1401 are provided on the opposite side surfaces of the opening. A guide wheel 15 is provided in the opening, and the end of the guide wheel 15 is located in the corresponding strip groove 1401. A clamping block 1402 sliding along the strip groove 1401 is installed at the lower end of the strip groove 1401, and a first spring 1403 is installed between the clamping block 1402 and the bottom surface of the strip groove, and the connecting rope 18 passes through the guide wheel 15.
[0037] The bottom surface of the cross groove 1001 is provided with four articulated seats 1002 distributed along the cross shape, and a push block 16 is rotatably installed on the articulated seat 1002. The four notches of the cross groove 1001 are all installed with rubber wheels 13. The rubber wheels 13 are located on the outside of the rotating wheel mounting seat 14. The push block 16 rotating outward pushes the rotating wheel mounting seat 14 close to the rubber wheel 13.
[0038] A prism 12 is fixed to the bottom end of the connecting rod 11, and a second spring 19 is sleeved on the outside of the connecting rod 11. The top of the connecting rod 11 extends to the other side through the circular hole 1003. The installed second spring 19 pushes the prism 12 away from the connecting seat 10, and the outer side of the prism 12 pushes the push block 16 to rotate outward.
[0039] A spring piece 17 is installed on the inner side of the push block 16 . The spring piece 17 is a C-shaped structure. The push block 16 is connected to the prism 12 via the spring piece 17 .
[0040] The two ends of the connecting rope 18 pass through the two guide wheels 15 distributed along the same straight line. After the installed connecting rope 18 passes through the two guide wheels 15 distributed along the same straight line, and the materials for road and bridge construction are fixed at both ends of the connecting rope 18, the connecting rope 18 pulls the wheel mounting seat 14 to a vertical state, so that after lifting, the connecting rope 18 moves along the guide wheel 15, thereby achieving the same force at both ends of the connecting rope 18, and a limiting groove is opened on the surface of the guide wheel 15 to prevent the connecting rope 18 from offsetting on the surface of the guide wheel 15.
[0041] Working principle: During the operation, the materials for road and bridge construction that need to be hoisted are connected through four connecting ends formed by two connecting ropes 18. At least two connecting ropes 18 are installed on the connecting seat 10. The connecting ends of the connecting ropes 18 are fixed with hooks to facilitate the connection between the connecting ends of the connecting ropes 18 and the supporting device for the bridge construction materials.
[0042] After hoisting, the road and bridge construction materials drive the connecting seat 10 to compress the second spring 19 under the action of gravity, so that the prism 12 approaches the push block 16, and the prism 12 pushes the push block 16 to rotate outward;
[0043] The installed connecting rope 18 passes through two guide wheels 15 distributed along the same straight line. After the road and bridge construction materials are fixed at both ends of the connecting rope 18, the connecting rope 18 pulls the runner mounting seat 14 toward a vertical state, so that the connecting rope 18 can move along the guide wheels 15 after lifting and installation, thereby achieving equal force at both ends of the connecting rope 18. A limiting groove is provided on the surface of the guide wheels 15 to prevent the connecting rope 18 from deflecting on the surface of the guide wheels 15.
[0044] If the connected end of the connecting rope 18 breaks, the pressure on the corresponding side of the wheel mounting seat 14 and the guide wheel 15 installed on the wheel mounting seat 14 is reduced, so that the push block 16 and the wheel mounting seat 14 are pushed to rotate outward under the action of the spring piece 17, so that the guide wheel 15 is pressed against the corresponding rubber wheel 13, and the connecting rope 18 is compressed. The road and bridge construction materials and the unbroken side of the connecting rope 18 move downward under weightlessness and pull the connecting rope 18. Since the connecting rope 18 is pressed against the corresponding rubber wheel 13 through the guide wheel 15, the resistance to pulling the connecting rope 18 is increased, thereby slowing down the moving speed of the road and bridge construction materials and the unbroken side of the connecting rope 18, effectively reducing the swinging and floating of the road and bridge construction materials, ensuring the stability of the lifting of the road and bridge construction materials, and thus preventing the road and bridge construction materials from falling off.
