As shown in fig. 4 to 10, an anti-damage sports car structure of a cable hoisting system includes: the car body and a plurality of sports car pulleys 03 that rotate around the first major axis 032 that sets up fixedly with respect to the car body, sports car pulleys 03 periphery is provided with the recess 031 that holds bearing wire rope 02, and the degree of depth of recess 031 is greater than the diameter of bearing wire rope 02.
The anti-damage sports car structure further comprises reset wheel bodies which are arranged in one-to-one correspondence with the sports car pulleys 03 up and down, wherein each reset wheel body is arranged in a rotating way around a second long shaft 1 which is parallel to the first long shaft 032, and the second long shaft 1 is fixedly arranged relative to the car body; the reset wheel body comprises a supporting inner ring 2, a curved elastic metal sheet 3 and a limiting outer ring 4 which are arranged around a second long shaft 1: two supporting surfaces 21 symmetrically arranged in a V shape are arranged on the periphery of the supporting inner ring 2, the symmetrical surfaces of the two supporting surfaces 21 are perpendicular to the second long shaft 1, and the sharp corner ends of the V shape are relatively far away from the second long shaft 1; the curved elastic metal sheets 3 are of annular structures and correspond to the supporting surfaces 21 one by one, the cross sections of the curved elastic metal sheets 3 are of arch structures, one side of a bulge 31 of each arch structure is fixedly connected with the supporting surface 21, and two edges 32 on one side of each bulge are relatively far away from the supporting surface 21; and the distance between the edge 32 on the inner side of the curved elastic metal sheet 3 and the symmetry plane is smaller than the distance between the protrusion 31 and the symmetry plane, and the distance between the edge 32 on the outer side and the symmetry plane is larger than the distance between the protrusion 31 and the symmetry plane.
The limiting outer rings 4 are in one-to-one correspondence with the curved elastic metal sheets 3 and are arranged at intervals with the sports car pulleys 03, and comprise inner inclined surfaces 41 and outer reset surfaces 42, the two adjacent limiting outer rings 4 are symmetrically attached and fixed to form a ring body structure for coating the supporting inner ring 2 and the curved elastic metal sheets 3, the inner inclined surfaces 41 are attached to the two edges 32 of the corresponding concave side of the curved elastic metal sheets 3, no fixed connection relation exists between the attachment of the inner inclined surfaces 41 and the two edges 32, and the two outer reset surfaces 42 are positioned in the grooves 031 and used for blocking and supporting the bearing steel wire ropes 02; the outer reset surfaces 42 are of cambered surface structures, and after the two limiting outer rings 4 are symmetrically attached, the two outer reset surfaces 42 form a smooth concave structure; through the arrangement of the structural form, when the bearing wire rope 02 applies force to the limiting outer ring 4 on one side, the bearing wire rope can enter the concave structure through guiding of the cambered surface structure, so that the two limiting outer rings 4 can be stressed together quickly, and the service life of the structure is prolonged; the distance between the edge of the outer reset surface 42 opposite to the outer side of the symmetry surface and the inner wall of the groove 031 is smaller than the diameter of the load-bearing wire rope 02.
The invention provides the anti-damage sports car structure which can not only effectively block the bearing steel wire rope 02 which is deviated, but also assist the bearing steel wire rope 02 to reset; through the arrangement of the inner curved elastic metal sheet 3, when the inner curved elastic metal sheet receives the acting force from the bearing steel wire rope 02, the inner curved elastic metal sheet 3 can buffer and assist in resetting through proper deformation; the damage to the self and the bearing steel wire rope 02 caused by friction can be reduced by the rotation setting mode of the self; meanwhile, the resistance to the bearing steel wire rope 02 can be reduced through the advantages, so that the damage-preventing sports car structure can run smoothly.
The reset wheel body can be preloaded firstly and then connected with the fixedly arranged rotating shaft structure through the bearing, wherein the fixedly arranged rotating shaft structure provides a second long shaft 1 and can be a long shaft fixed through a vehicle body or a plurality of short shafts fixed through the vehicle body, and the reset wheel body is within the protection scope of the invention. Before preassembling, the support inner ring 2, the curved elastic metal sheet 3 and the limiting outer ring 4 are required to be machined, and then the curved elastic metal sheet 3 is fixedly installed relative to the support surface 21 of the support inner ring 2; after the installation is completed, the two limiting outer rings 4 are subjected to butt joint installation, so that the two inner inclined planes 41 at the two sides are respectively attached to the two side edges 32 of the curved elastic metal sheet 3, and finally the fixed connection of the two limiting outer rings 4 is completed. In the above process, the fixed connection of the limit outer ring 4 may be non-detachable, for example, by welding; in order to facilitate the replacement and adjustment of the components, the fixed connection of the limiting outer ring 4 is preferably detachable, specifically, the two limiting outer rings 4 are fixed by the connecting piece 5. The supporting inner ring 2 and the limiting outer ring 4 can be obtained through casting, and then a precise structure is obtained through machining.
In the working process, as shown in fig. 8, when the bearing wire rope 02 moves downwards relative to the left direction in the figure and deviates outwards from the groove 031 and contacts with the reset wheel body, the limit outer ring 4 of the reset wheel body inclines leftwards and deviates downwards, the inclination can enable the top of the curved elastic metal sheet 3 on the left side in the figure to deform in a certain range because of being extruded, the deformation can buffer the impact from the bearing wire rope 02, the elastic reset force is used for assisting the reset of the bearing wire rope 02, and in the process, the whole reset wheel body rolls relative to the bearing wire rope 02, so that the relative friction force between the two is small, and the damage to each part is controllable; in operation, the supporting inner ring 2 and the limiting outer ring 4 should avoid the process of collision, and the service life of the supporting inner ring and the limiting outer ring can be ensured by controlling the sizes of the positions of the structures, except for other limiting purposes.
The effect is consistent with the above when the load-bearing wire 02 moves downward with respect to the right direction in the drawing, and is deviated to the outside of the groove 031 and contacts the return wheel body. When the load-bearing steel wire rope 02 is not inclined and is vertically deflected downwards as shown in the figure, the limiting outer ring 4 of the reset wheel body can vertically move downwards, at this time, the tops of the curved surface elastic metal sheets 3 on two sides are deformed in a certain range due to being extruded, and the effect achieved by the deformation is the same as that in the description, and the description is omitted. In the above case, the distance between the inner edge 32 of the curved elastic metal sheet 3 and the symmetry plane is smaller than the distance between the protrusion 31 and the symmetry plane, and the distance between the outer edge 32 and the symmetry plane is larger than the distance between the protrusion 31 and the symmetry plane, so that when the curved elastic metal sheet 3 is extruded, the elastic opening of the open end can be obtained, rather than the displacement of the protrusion 31 caused by the dislocation of the curved elastic metal sheet relative to the supporting surface 21, thereby avoiding the installation problem.
In the above embodiment, when the reset wheel body receives the extrusion from any direction of the bearing steel wire rope 02, the flexible buffer characteristic of the reset wheel body due to the arrangement of the curved elastic metal sheet 3 can change the relation of hard collision with the bearing steel wire rope 02, which can effectively reduce the friction force generated between the reset wheel body and the bearing steel wire rope 02, thereby reducing the respective abrasion and reducing the influence degree on the running of the sports car structure.
In the implementation process, the required elastic restoring force and the elastic deformation range can be changed by the factors of the material, the size, the bending form and the like of the curved elastic metal sheet 3, and the corresponding support inner ring 2 and the corresponding limit outer ring 4 also need to be correspondingly changed in size when the size of the curved elastic metal sheet is changed; wherein the curved elastic metal sheet 3 can be obtained by means of stamping. When the reset wheel body rotates, the three parts can be ensured to synchronously rotate due to the relative friction force among the supporting inner ring 2, the curved elastic metal sheet 3 and the limiting outer ring 4.
For the above embodiment, the depth of the groove 031 is larger than the diameter of the load-bearing wire rope 02, the outer reset surface 42 is located in the groove 031, and it is also particularly critical that the distance between the outer reset surface 42 and the inner wall of the groove 031 is smaller than the diameter of the load-bearing wire rope 02, with respect to the edge of the outer side of the symmetry surface, so that the load-bearing wire rope 02 does not risk being deviated from the groove 031 by the above structure.
In order to protect the reset wheel, as a preferable embodiment, the limiting outer ring 4 is further provided with an annular limiting part 43, and the limiting part 43 is located in the groove 031 and is arranged around the second long shaft 1; when the position of the bearing wire rope 02 is correct, the limiting part 43 is arranged at intervals with the inner wall of the groove 031, and when the limiting outer ring 4 is deflected due to the deflection of the bearing wire rope 02, the limiting part 43 is attached to the inner wall of the groove 031 to limit the deflection of the limiting outer ring 4 to the maximum extent.
In the invention, the cross section size of the groove 031 can be properly increased, so that the set position of the limiting outer ring 4 can be effectively accommodated, and the curved elastic metal sheet 3 can be effectively prevented from being damaged due to excessive deformation by the arrangement of the limiting part 43. In practice, the stop 43 may be planar, as illustrated in fig. 8, in which case the stop 43 is preferably obtained directly by machining the stop collar 4; alternatively, preferably, the limiting portion 43 is an elastic ring structure and is fixedly connected to the limiting outer ring 4.
During specific implementation, the cross section of the limiting part 43 can be selected according to the needs, the damage to the sports car pulley 03 and the limiting outer ring 4 can be reduced in the collision process through the arrangement of the elastic structure, during specific installation, the fixed connection can be realized through a pasting mode, or the annular groove body is formed in the limiting outer ring 4, the limiting part 43 with the annular structure is locally embedded into the annular groove body to realize fixation, and due to the elasticity of the limiting part 43, the installation mode can realize fixation under the condition of no connecting piece 5 and is convenient to install.
As a preference in the above embodiment, when the position of the load-bearing wire rope 02 is correct, the outer resetting surface 42 is spaced from the load-bearing wire rope 02, in this way, a certain deviation of the load-bearing wire rope 02 can be allowed, and the running-car structure is helpful for the working smoothness of the running-car structure and the service life of the resetting wheel body can be prolonged under the condition of enough guarantee of the running-car structure.
In order to further ensure the technical effect in the above embodiment, after the two limiting outer rings 4 are symmetrically attached and fixed, a V-shaped included angle is formed between the two inner inclined surfaces 41, and the included angle is greater than or equal to 90 °. When the included angle is in a proper large range, the curved elastic metal sheet 3 can be effectively pressed instantly by a relatively gentle slope, so that the curved elastic metal sheet 3 generates enough elastic deformation to assist the reset of the bearing steel wire rope 02, and meanwhile, the impact on the connection position of the bulge 31 and the supporting surface 21 can be reduced, thereby ensuring the installation stability of the curved elastic metal sheet 3.
In the implementation process, the cross section of the curved elastic metal sheet 3 is in an axisymmetric pattern, and two edges of one side of the concave of the curved elastic metal sheet 3 are symmetrically arranged about the symmetry axis, so that the dimension control is easier to realize, and in this case, the symmetry plane penetrating through the bulge 31 is perpendicular to the supporting surface 21, so that the positioning and mounting difficulty of the curved elastic metal sheet 3 can be reduced.
As a preferable mode of the above embodiment, the limiting outer ring 4 further includes a protecting flange 44 connected to the inner edge of the inner inclined surface 41 and extending toward the second long shaft 1, and spaced from the supporting inner ring 2; the included angle between the inner side surface of the protection convex edge 44 relative to the symmetry plane and the inner inclined plane 41 is 120-150 degrees. As shown in fig. 8, by the arrangement of the protection flange 44, the gap between the limit outer ring 4 and the support inner ring 2 can be blocked to a certain extent, so as to realize protection, in addition, the deformation degree of the curved elastic metal sheet 3 can be limited by the included angle between the inner side surface and the inner inclined surface 41, specifically, when the curved elastic metal sheet 3 is deformed to a position where one side edge 32 abuts against the included angle, the deformation can be limited to avoid further deformation, so as to ensure the elastic resetting capability.
For the installation of the curved elastic metal sheet 3, it is preferable that the curved elastic metal sheet 3 is fixedly connected with the supporting surface 21 through the connecting piece 5. In this way, through holes can be first formed in the curved elastic metal sheet 3, and the curved elastic metal sheet is sleeved on the supporting surface 21 during installation to achieve attachment to the supporting surface 21, then holes are drilled in the supporting surface 21 according to the positions of the through holes, and finally the connecting piece 5 can be installed by drilling the completed holes, so that the fixed connection between the curved elastic metal sheet 3 and the supporting surface 21 is completed.

It will be understood by those skilled in the art that the present invention is not limited to the embodiments described above, and that the above embodiments and descriptions are merely illustrative of the principles of the present invention, and various changes and modifications may be made without departing from the spirit and scope of the invention, which is defined in the appended claims.
