During transfer, the vehicle seat 10 is pulled using a strap. After the structural member top support installation and transfer trolley moves into place, it can be horizontally moved or rotated in-situ using the universal wheels, and then the first lifting device 40, the second lifting device 50, and the third lifting device 60 are lifted and lowered simultaneously, or one or two of them are lifted and lowered, to adjust the height of the load platform 30 or the angle of the load platform 30, ensuring that the interfaces of the structural members are aligned and installed.

[0045] In the structural member top support installation and transfer trolley of the present utility model, due to having wheels, three lifting devices, and the special connection methods between the three lifting devices and the vehicle seat 10 and the load platform 30, the load platform 30 has a large movement amount in five degrees of freedom directions, facilitating the five-degree-of-freedom adjustment of the structural member on the load platform 30, realizing the adjustment of the height and angle of the structural member, and facilitating the installation and disassembly of the structural member. Moreover, due to having the load platform 30, it can be installed from bottom to top, which can solve the installation and disassembly problems of structural members that cannot be hoisted and installed, achieving the effect of facilitating the installation and disassembly of structural members and being beneficial to improving the installation and disassembly efficiency.

[0046] In some embodiments of the present utility model, such asFigure 3 and Figure 4 As shown in Figure 4 , both the first universal hinge structure and the third universal hinge structure include a first connecting seat 71, a first rotating shaft 72, and a second rotating shaft 73. The first connecting seat 71 is fixedly installed on the seat 10. The first rotating shaft 72 is rotatably installed on the first connecting seat 71. The second rotating shaft 73 is rotatably installed on the first rotating shaft 72, and the axis of the second rotating shaft 73 is in the same plane as the axis of the first rotating shaft 72. The lifting device is fixedly or rotatably installed on the second rotating shaft 73. In some alternative embodiments of the present invention, the second rotating shaft 73 is fixedly installed on the first rotating shaft 72, and the axis of the second rotating shaft 73 is in the same plane as the axis of the first rotating shaft 72. The lifting device is rotatably installed on the second rotating shaft 73. In some embodiments of the present invention, both the first universal hinge structure and the third universal hinge structure are Hooke joints, such as cross-axis type Hooke joints.

[0047] In some embodiments of the present invention, such as Figure 5As shown, the first rotating shaft 72 includes a first pin shaft 721 and a second pin shaft 722 that are coaxially arranged and fixedly connected. Both the first universal hinge structure and the third universal hinge structure further include a connecting block 74 and a stepped screw 75. The connecting block 74 is provided with a first through hole, a second through hole, and a stepped screw hole. Among them, the first through hole, the second through hole, and the stepped screw hole are orthogonally arranged in pairs. The second rotating shaft 73, the first pin shaft 721, and the second pin shaft 722 cooperate with each other inside the connecting block 74 by means of a wedge structure and are fastened to the connecting block 74 by the stepped screw 75. Specifically: The second rotating shaft 73 is a cylindrical structure, and two symmetrically arranged grooves are cut in the middle of the cylinder: an upper groove and a lower groove; among them, a hole for the first pin shaft 721 is provided on the spacer plate between the upper groove and the lower groove. Further, one end of the first pin shaft 721 is a cylindrical structure, and the other end is a flat first rectangular cantilever, and a hole for the second pin shaft 722 is provided on the first rectangular cantilever; one end of the second pin shaft 722 is a cylindrical structure, and the other end is a flat second rectangular cantilever, and a hole for a third pin shaft is provided on the second rectangular cantilever. During assembly, the first rectangular cantilever is nested and installed in the upper groove of the second rotating shaft 73, the second rectangular cantilever is nested and installed in the lower groove of the second rotating shaft 73, and the holes of the first pin shaft 721, the holes of the second pin shaft 722, the holes of the third pin shaft, and the stepped screw hole are coaxial. The stepped screw 75 is threadedly connected to the stepped screw hole and passes through the holes of the first pin shaft 721, the holes of the second pin shaft 722, and the holes of the third pin shaft. The connecting block 74 is an equilateral quadrangular prism structure, and an arc chamfer is cut on the equilateral quadrangular prism structure to increase the movement range and prevent structural interference. The force between the seat 10 and the loading platform 30 is mainly transmitted through the connecting block 74, thereby enhancing the overall structural stiffness of the first universal hinge structure and the third universal hinge structure. The forces in all directions acting on the corresponding second lifting device 50 or the third lifting device 60 are transmitted to the first connecting seat 71 through the connecting block 74; the forces in all directions acting on the first connecting seat 71 are transmitted to the corresponding second lifting device 50 or the third lifting device 60 through the connecting block 74; the force transmission link is short and the structural stiffness is high, which is suitable for occasions that need to bear a large transmission torque or lateral force.

[0048] In some embodiments of the present invention, the axis of the first rotating shaft 72 is arranged parallel to the horizontal axis, and the horizontal axis extends in the front-rear direction. By such an arrangement, the adjustment of the angle of the loading platform 30 is more accurate and the docking is more convenient.

[0049] In some embodiments of the present invention, both the second universal hinge structure 51 and the fourth universal hinge structure 61 are spherical hinges.

[0050] In some embodiments of the present invention, such as Figures 2 to 4As shown, the first lifting device 40, the second lifting device 50, and the third lifting device 60 all include a second connecting seat 81 and a lifting screw 82. The second connecting seat 81 has a lifting cylinder, and a thread is provided inside the lifting cylinder. The lifting screw 82 extends into the lifting cylinder and is threadedly connected to the lifting cylinder. The relative rotation of the lifting screw 82 with respect to the lifting cylinder can achieve extension and ascent or retraction and descent.

[0051] In some embodiments of the present utility model, the structural member top support installation transfer trolley further includes a first top plate 43, a second top plate 53, and a third top plate 63. The first top plate 43 is fixedly connected to the lower side of the load platform 30. A rotating cylinder is provided on the lower side of the first top plate 43. The upper end of the lifting screw 82 of the first lifting device 40 is inserted into the rotating cylinder 41 and is rotatably connected to the rotating cylinder 41, so that the upper end of the first lifting device 40 is rotatably mounted on the load platform 30 around the vertical axis. The second top plate 53 is fixedly connected to the lower side of the load platform 30. A ball hinge groove is provided at the upper end of the lifting screw 82 of the second lifting device 50, and the corresponding ball hinge is fixedly connected to the lower side of the second top plate 53, and the ball hinge is installed in the ball hinge groove. The third top plate 63 is fixedly connected to the lower side of the load platform 30. A ball hinge groove is provided at the upper end of the lifting screw 82 of the third lifting device 60, and the corresponding ball hinge is fixedly connected to the lower side of the third top plate 63, and the ball hinge is installed in the ball hinge groove. When the first lifting device 40 is lifted or lowered, since the rotating cylinder and the lifting screw 82 are rotatably connected, the rotating cylinder does not hinder the rotation of the lifting screw 82, and at the same time, the rotation will also rotate relative to the vehicle seat 10, realizing adjustment actions of the load platform 30 such as the left and right swing of the rear end of the load platform 30. Similarly, the design of the ball hinge groove and the ball hinge also does not hinder the rotation of the lifting screw 82 and at the same time realizes its own function.

[0052] That is to say, in the structural member top support installation transfer trolley of the embodiments of the present utility model, the lifting devices all include the lifting screw 82. The setting of the ball hinge and the rotating cylinder enables the lifting screw 82 not to consider the influence of the load platform 30 on the rotation of the screw when extending and retracting, that is, there is no need to provide a special connecting device between the lifting screw 82 and the load platform 30 for allowing the lifting screw 82 to rotate. That is, the setting of the ball hinge and the rotating cylinder does not affect the rotation of the lifting screw 82, and at the same time realizes the function of convenient disassembly and installation of the structural member, making use of the structural characteristics with one object serving two purposes and fully utilizing the structural features, which can simplify the structure and make the structure simple and compact.

[0053] In some alternative embodiments of the present utility model, the corresponding ball hinge is fixedly connected to the upper end of the lifting screw 82 of the second lifting device 50, a ball hinge groove is provided on the lower side of the second top plate 53, and the ball hinge is installed in the ball hinge groove. The corresponding ball hinge is fixedly connected to the upper end of the lifting screw 82 of the third lifting device 60, a ball hinge groove is provided on the lower side of the third top plate 63, and the ball hinge is installed in the ball hinge groove.

[0054] In some embodiments of the present utility model, a turning arm 83 is provided on the lifting screw rod 82, and the turning arm 83 is horizontally arranged. The turning arm 83 can also be referred to as a handle and is used for manual rotation to achieve lifting. In some alternative embodiments of the present utility model, a motor and a transmission mechanism are installed on the second connecting seat 81, and the motor drives the lifting screw rod 82 to rotate through the transmission mechanism.

[0055] In some embodiments of the present utility model, as Figure 6 shown, the universal wheel device 20 includes a wheel frame 21, wheels 22, a first brake pad 23, a second brake pad 24, and a spring 25. The wheel frame 21 is rotatably mounted on the seat 10 about a vertical axis. The wheels 22 are rotatably mounted on the wheel frame 21 about a horizontal axis. The first brake pad 23 is arranged on the front side of the wheel, and the first brake pad 23 is rotatably mounted on the wheel frame 21 through a first connecting frame 26. The second brake pad 24 is arranged on the rear side of the wheel, and the second brake pad 24 is rotatably mounted on the wheel frame 21 through a second connecting frame 27. The spring 25 is arranged between the first connecting frame 26 and the second connecting frame 27. When both the first brake pad 23 and the second brake pad 24 are in contact with the wheel 22, the spring 25 is in a stretched state, urging the brake pads to press tightly against the wheel 22 for braking. When both the first brake pad 23 and the second brake pad 24 rotate upward and are disengaged from the wheel 22 to be in a non-braking state, the spring 25 is in a stretched state, keeping the first brake pad 23 and the second brake pad 24 in their current positions to prevent contact with the wheel 22 and prevent interference with the transfer of the transfer trolley supported by the structural member.

[0056] In some embodiments of the present utility model, as Figure 6As shown in the figure, the first connecting bracket 26 is rotatably mounted on the wheel bracket 21 through the third rotating shaft 28, and the second connecting bracket 27 is rotatably mounted on the wheel bracket 21 through the fourth rotating shaft 29. The third rotating shaft 28 is located below the fourth rotating shaft 29. Since the third rotating shaft 28 is located below the fourth rotating shaft 29, after the first connecting bracket 26 rotates upward to the non-braking state, the spring 25 can be in a stretched state. At this time, the spring 25 passes through the position between the third rotating shaft 28 and the fourth rotating shaft 29, so that the second brake pad 24 can always be in the braking state. When in use, the second brake pad 24 can be rotated downward for braking first. When further braking is required, the first brake pad 23 is rotated downward for braking. When releasing the brake, the second brake pad 24 can be rotated upward. After the second brake pad 24 rotates upward to the preset position and the spring 25 moves to the position passing through the position between the third rotating shaft 28 and the fourth rotating shaft 29, it will drive the first brake pad 23 to rotate upward to release the brake. That is, when releasing the brake, it is not necessary to act on both brake pads. If partial braking is to be released, the first brake pad 23 can be rotated upward to release the braking of the first brake pad 23, and the second brake pad 24 can continue to maintain the braking state. The diversification of braking is significantly improved, and different braking methods can be selected according to different structural component road conditions. The structure is simple and the operation is convenient. Further, a limiting device for limiting the maximum upward rotation positions of the first connecting bracket 26 and the second connecting bracket 27 is further provided on the wheel bracket 21.

[0057] The structural member top support installation transfer trolley according to the embodiment of the present invention has the capabilities of walking and positioning, can realize the short-distance transfer of structural members, that is, can realize the transfer of structural members and the like indoors, can also transport the structural members to the working position, and perform the adjustment of angle and height. There is a large margin in all directions, so that the structural members can realize five-degree-of-freedom movement, can meet the self-bottom-up installation of various types of structural members, that is, can perform auxiliary installation, can solve the installation and disassembly problems of structural members that cannot be hoisted and installed, and achieve the effect of facilitating the installation and disassembly of structural members, which is beneficial to improving the installation and disassembly efficiency. The walking adopts a wheeled structure with universal wheels. The wheels can include soft protective layers such as nylon and rubber, or softer materials such as nylon and rubber are selected for paving on the walking road surface of the wheels to avoid scratches and indentations caused by the movement of the structural member top support installation transfer trolley.

[0058] At this point, those skilled in the art should recognize that although many exemplary embodiments of the present invention have been shown and described in detail herein, still, without departing from the spirit and scope of the present invention, many other variations or modifications that conform to the principles of the present invention can be directly determined or derived from the content disclosed in the present invention.
