During assembly, operators can only manually move parts for assembly, resulting in high labor intensity and low production efficiency. Existing simple hoists with I-beam structures all require installing rails on the factory building and then installing electric hoists. However, the existing old factory buildings do not have the installation conditions. Content of the Utility Model

[0003] The technical problem to be solved by the utility model is to provide a simple suspension structure with a relatively wide application range, which can significantly reduce the labor intensity of operators and significantly improve production efficiency.

[0004] The technical solution adopted to solve the above technical problem is: a simple suspension structure, which includes a support connection frame, a rotary connection mechanism, and a cantilever hanger with a slide rail. The cantilever hanger is arranged on the support base along the horizontal direction of the slide rail through the cooperation of the support connection frame and the rotary connection mechanism.

[0005] Furthermore, the support connection frame includes at least two groups of rigid clamps. Each group of rigid clamps is vertically clamped on the support base in sequence, and the connection end of the support connection frame is hinged to each group of rigid clamps through the rotary connection mechanism.

[0006] The preferred mode of the above solution is that each group of rigid clamps includes at least one back plate, two sets of tightening bolt pairs, and a connection sub-frame. The support connection frame also includes at least one group of support limiting members. Each connection sub-frame is respectively clamped on the support base through the corresponding back plate and tightening bolt pairs in an adaptable position. At least one support limiting member is respectively arranged between adjacent two connection sub-frames, and each connection sub-frame is respectively hinged to the rotary connection mechanism.

[0007] Furthermore, the back plate included in each group of rigid clamps is two, the tightening bolt pairs included in each group of rigid clamps are four sets, each connection sub-frame is respectively welded by a main back plate and a horizontal connecting plate. Each main back plate is respectively clamped on the support base in an adaptable position through four sets of tightening bolt pairs in the cooperation of the corresponding back plate. Each connection sub-frame is respectively hinged to the rotary connection mechanism through the corresponding horizontal connecting plate. Each support limiting member is composed of a square tube. The distance between adjacent two horizontal connecting plates is respectively limited by at least one square tube.

[0008] Preferably, the supporting connection frame includes two sets of rigid clamps, the rotary connection mechanism includes two sets of rotary hinge structures, and the upper and lower ends of the cantilever hanger along the vertical direction are respectively hinged to the corresponding horizontal connecting plates through a set of rotary hinge structures.

[0009] Furthermore, each set of rotary hinge structures respectively includes at least one mounting shaft and a set of tapered roller bearings. Bearing seats are respectively arranged at the upper and lower ends of the cantilever hanger along the vertical direction, and the tapered roller bearings arranged on the corresponding horizontal connecting plates through the mounting shafts are respectively located in the corresponding bearing seats.

[0010] Preferably, each set of rotary hinge structures also respectively includes a set of mounting plate groups, and each mounting shaft is fixedly installed on the corresponding horizontal connecting plate through the corresponding mounting plate group.

[0011] Furthermore, a damping washer is also padded between the bearing seat at the lower end of the cantilever hanger along the vertical direction and the mounting plate group.

[0012] Preferably, the cantilever hanger is a triangular welded truss formed by welding a horizontal I-beam, a vertical bearing installation rod, and at least one diagonal bracing rod. Bearing seats are respectively arranged at the upper and lower ends of the vertical bearing installation rod, and the slide rail is formed by the flange of the horizontal I-beam.

[0013] Furthermore, there are two diagonal bracing rods, and each diagonal bracing rod is composed of a square tube. The support foundation is a column at the corresponding position in the factory building or a column set at a predetermined position in the factory building.

[0014] The beneficial effect of the present utility model is that: the technical solution provided by this application adopts a simple suspension structure including a supporting connection frame, a rotary connection mechanism, and a cantilever hanger with a slide rail. Then, the cantilever hanger is arranged on the support foundation along the horizontal direction of the slide rail through the cooperation of the supporting connection frame and the rotary connection mechanism. In this way, when hoisting and assembling parts, only a manual or electric hoist needs to be installed on the slide rail of the cantilever hanger. Moreover, since the cantilever hanger is arranged on the support foundation through the rotary connection mechanism, the manual or electric hoist arranged on the slide rail can not only move along the length direction of the slide rail, but also rotate within a circular range with the length of the slide rail as the radius, increasing the hoisting range of the simple suspension structure of this application. Since the simple suspension structure of this application is used to hoist the parts to be assembled in cooperation with a manual or electric hoist, the technical problem that only manual lifting and assembly can be performed at positions where the traveling crane cannot reach in the prior art is solved. It can not only significantly reduce the labor intensity of operators and significantly improve production efficiency, but also significantly increase the usage range of the simple suspension structure of this application because the cantilever hanger of this application only requires a column or other foundations that can fixedly support the connection frame.

The technical solution provided in this application is a simple suspension structure including a support connection frame, a rotary connection mechanism, and a cantilever hanger with a slide rail. Then, the cantilever hanger is arranged on the support foundation along the horizontal direction with the slide rail extending through the cooperation of the support connection frame and the rotary connection mechanism. In this way, when lifting and assembling parts, only a manual or electric hoist needs to be installed on the slide rail of the cantilever hanger. Moreover, since the cantilever hanger is arranged on the support foundation through the rotary connection mechanism, the manual or electric hoist arranged on the slide rail can not only move along the length direction of the slide rail, but also rotate within a circular range with the length of the slide rail as the radius, increasing the lifting range of the simple suspension structure of this application. Since the simple suspension structure of this application is used in cooperation with a manual or electric hoist to lift the parts to be assembled, the technical problem in the prior art that when the position where the traveling crane cannot reach can only be manually carried and assembled is solved. It can not only significantly reduce the labor intensity of operators and significantly improve production efficiency, but also, since the cantilever hanger of this application only needs a column or other foundation that can fixedly support the connection frame, the use range of the simple suspension structure of this application can be significantly increased.

The support connection frame also includes at least one group of support limiting members 5. Each connecting sub-frame 4 is respectively clamped onto the support foundation 1 through the corresponding back plate 2 and the clamping bolt pairs 3 with adapted positions. At least one support limiting member 5 is arranged between adjacent two connecting sub-frames 4, and each connecting sub-frame 4 is respectively hinged to the rotary connection mechanism. Each set of rotary hinge structures respectively includes at least one mounting shaft 6 and a set of tapered roller bearings 7. Bearing seats 8 are respectively arranged at the upper and lower ends of the cantilever hanger vertically, and the tapered roller bearings 7 arranged on the corresponding horizontal connecting plates through the mounting shaft 6 are respectively located in the corresponding bearing seats 8.

[0020] A more specific structure is that each group of rigid hoops includes two back plates 2, each group of rigid hoops includes four sets of clamping bolt pairs 3, each connecting sub-frame 4 is formed by welding a main back plate and a horizontal connecting plate, and each main back plate is respectively clamped onto the support foundation 1 through four sets of clamping bolt pairs 3 in cooperation with the corresponding back plate 2 with adapted positions. Each connecting sub-frame 4 is respectively hinged to the rotary connection mechanism through the corresponding horizontal connecting plate. Each support limiting member 5 is formed by a square tube, and the distance between adjacent two horizontal connecting plates is respectively limited by at least one square tube. Each set of rotary hinge structures also respectively includes a group of mounting plate sets 9, and each mounting shaft 6 is fixedly installed on the corresponding horizontal connecting plate through the corresponding mounting plate set 9.
