In addition, those skilled in the art can combine and combine different embodiments or examples described in this specification and features of different embodiments or examples without contradiction.

[0039] With the development of cableway transportation technology, cable cars or ropeways, as a means of transportation that moves vertically and horizontally, have broad application prospects in scenic spots, mining or material transportation.

[0040] Existing cableway structures typically utilize a suspended steel wire rope to support and pull a sling. A grip 10 is typically connected to the wire rope, fixedly connected to the rope. As the rope moves, it drives the grip 10 with it. The main shaft 11 of the grip 10 extends horizontally, perpendicular to the wire rope, and is located on one side of the rope. To ensure that the grip 10 and the sling connected to it (e.g., a cable car car or basket) can smoothly pass over the supporting frame, guide wheels, and steering wheels that support the wire rope, the main shaft 11 of the grip 10 typically extends only along one side of the wire rope's radial direction (i.e., it typically extends eccentrically relative to the wire rope). This allows the sling to be attached to the main shaft 11, creating an eccentric connection with the wire rope.

[0041] Specifically, refer to Figure 1 and Figure 2 As shown, Figure 1 This is a schematic diagram of the explosion structure of the rope gripper and the boom sleeve in the related art. Figure 2 It is a cross-sectional view of the cooperation between the main shaft of the rope gripper and the boom sleeve in the related art.

[0042] Reference Figure 1 As shown, in the related art, one side of the rope gripper 10 has an inner gripper and an outer gripper (not shown in the figure), and the rope gripper 10 is fixed to the wire rope through the cooperation of the inner gripper and the outer gripper. A horizontally extending main shaft 11 is provided on the other side of the rope gripper 10.

[0043] Reference Figure 1 and Figure 2 As shown, the sling (not shown in the figure) generally has a sling 20. In the related art, a sling sleeve 21 is usually welded on the sling 20, wherein a sliding bearing 22 is provided in the sling sleeve 21. Figure 1 As shown, in the related art, the main shaft 11 of the rope grip 10 passes through the boom sleeve 21, and a locking member 40 is provided at the end of the boom sleeve 21 away from the rope grip 10, so as to limit the boom sleeve 21 and the main shaft 11 of the rope grip 10 to be connected together, thereby realizing the connection between the rope grip 10 and the sling.

[0044] It can be understood that when the wire rope drives the sling through the rope grip 10 to move, acceleration and deceleration are inevitable. The sling is suspended in the air and will swing more significantly and more times due to inertia. In the related art, two flat gaskets 50 (generally referred to as flat friction plates in the prior art) are set at both ends of the boom sleeve 21 along the axial direction. The flat gaskets 50 are in contact with the end face of the boom sleeve 21, thereby increasing the friction resistance encountered by the boom sleeve 21 during rotation and reducing the swing of the boom sleeve 21.

[0045] However, referring to Figure 2 As shown, the sling is suspended on the main shaft 11, and the sling's weight line is eccentric with the axis of the wire rope. This means that the sling's weight line exerts downward pressure on the main shaft 11 vertically and on one side of the wire rope axis, i.e., an eccentric force. This causes the axis of the main shaft 11 to deviate relative to the horizontal plane of the wire rope center. Furthermore, the axis of the boom sleeve 21 also deviates relative to the horizontal plane of the wire rope center. In other words, due to the eccentric force, the axis of the boom sleeve 21 and the axis of the main shaft 11 of the grip 10 cannot be parallel to the horizontal plane of the wire rope center. Furthermore, because the boom sleeve 21 and the main shaft 11 of the grip 10 use a clearance fit, the eccentric force prevents the axes of the main shaft 11 of the grip 10 and the boom sleeve 21 from remaining parallel. This means that the axes of the main shaft 11 and the boom sleeve 21 form a certain angle.

[0046] Reference Figure 2 As shown in the actual application environment, Figure 2 In the contact area shown at A and C, the inner wall of the boom sleeve 21 and the main shaft 11 of the cable grip 10 will squeeze each other. Figure 2In the contact areas shown at B and D, due to the axial angle between the boom sleeve 21 and the main shaft 11, there is a certain gap between the inner circumference of the boom sleeve 21 and the main shaft 11 of the rope grip 10, resulting in uneven contact between the inner circumference of the boom sleeve 21 and the main shaft 11. The wear is severe in the extrusion area of ​​the diagonal contact, while there is almost no extrusion at the other diagonal position, which leads to uneven wear on the axial surface and end surface of the boom sleeve 21. As the cableway hoist is used for a longer time, abnormal noise, vibration and other phenomena will occur, which will seriously affect the stability and safety of the hoist operation.

[0047] Continue to refer to Figure 2 As shown, under the action of the gravity of the sling, the axis of the main shaft 11 is at a certain angle relative to the axis of the boom sleeve 21 (deflected at a certain angle relative to the horizontal direction); at this time, the contact between the end face of the boom sleeve 21 and the plane gasket is transformed from surface contact to point-line contact; for example, referring to Figure 2 As shown, in Figure 2 In the contact area between E and F, the contact area between the end face of the boom sleeve 21 and the flat gasket will be reduced, and a certain gap will be generated. The pressure between the end face of the boom sleeve 21 and the flat gasket will also be reduced. Figure 2 In the contact areas at G and H, the mutual squeezing force between the end face of the boom sleeve 21 and the plane gasket 50 increases, and at G and H, the contact area between the end face of the boom sleeve 21 and the plane gasket 50 also decreases, resulting in the conversion of the plane friction pair between the end face of the boom sleeve 21 and the plane gasket 50 into a high-pair kinematic pair with point-line contact.

[0048] Understandably, Figure 2 Pressure concentration will occur in the contact area between G and H, which will cause the flat gasket 50 to break and fall due to uneven force, seriously affecting the safety of the cableway.

[0049] Figure 3 : is a schematic diagram of the exploded structure of the cableway sling connection device provided by an embodiment of the present invention, Figure 4 It is a schematic diagram of the exploded structure of the coordination of the boom sleeve, the first gasket and the second gasket in the cableway sling connection device provided by an embodiment of the present invention.

[0050] Regarding the technical problems existing in related technologies, refer to Figure 3 and Figure 4 As shown, an embodiment of the present invention provides a cableway sling connection device, including: a rope gripper 100 and a sling sleeve 201.

[0051] Specifically, in the embodiment of the present invention, the rope grip 100 may be a fixed rope grip or a detachable rope grip. In the embodiment of the present invention, a detachable rope grip is used as a specific example for illustration.

[0052] The end of the rope gripper 100 body close to the wire rope has an inner gripper and an outer gripper (not shown in the figure). Through the cooperation of the inner gripper and the outer gripper, the rope gripper 100 and the wire rope can be fixedly connected. Figure 3 As shown, the other end of the gripper 100 has a main shaft 101 extending in the horizontal direction, wherein Figure 2 As shown, the main shaft 101 is inserted into the boom sleeve 201, thereby realizing the connection between the rope grip 100 and the spreader (not shown in the figure). Specifically, the boom sleeve 201 is connected to the boom, and the boom is connected to the spreader.

[0053] In an optional embodiment of the present invention, the boom sleeve 201 is formed by welding a sleeve to the end of the boom 200 near the grip 100, and disposing a sliding bearing 22 within the boom sleeve 201. The sliding bearing 22 is disposed within the boom sleeve 201. Specifically, the sliding bearing 22 and the boom sleeve 201 are fixedly connected by an interference fit, thereby limiting relative movement between the sliding bearing 22 and the boom sleeve 201.

[0054] In another optional example of the present invention, a first curved surface 2011 is provided on the end face of the boom sleeve 201. The first curved surface 2011 can be a concave surface. Specifically, the end face of the sleeve is concave inward to form the first curved surface 2011. The first curved surface 2011 can be formed integrally with the boom sleeve 201, such as by integrally forming the first curved surface 2011 on the end face of the boom sleeve 201 by casting or pouring.

[0055] In another optional example of the present invention, the first curved surface 2011 can also be obtained by secondary processing on a machine tool after the boom sleeve 201 is manufactured, for example, by removing a portion of the end surface of the boom sleeve 201 by a milling machine or a grinder.

[0056] In some other optional examples of the present invention, the first arc-shaped surface 2011 may also be a convex surface, and the specific formation method is similar to the above and will not be repeated.

[0057] In an optional embodiment of the present invention, as shown in FIG3 , the cableway sling connection device further includes a first washer 300 , and the first washer 300 is sleeved on the main shaft 101 of the cable grip 100 .

[0058] Specifically, refer to Figure 3 and Figure 4As shown, in the embodiment of the present invention, a first gasket 300 is provided at each of the two axial ends of the boom sleeve 201. That is to say, in the embodiment of the present invention, two first gaskets 300 are provided, one of the two first gaskets 300 is provided at one end of the boom sleeve 201, and the other of the two first gaskets 300 is provided at the other end of the boom sleeve 201.

[0059] In the embodiment of the present invention, referring to Figure 4 As shown, the first gasket 300 has a second curved surface 301 on the side facing the boom sleeve 201, and the second curved surface 301 matches the first curved surface 2011 on the end face of the boom sleeve 201. In other words, the shapes of the first curved surface 2011 and the second curved surface 301 are suitable for making the end face of the boom sleeve 201 fit together with the first gasket 300.

[0060] It can be understood that when the first curved surface 2011 is set as an inner concave surface, the second curved surface 301 is a matching outer convex surface, and when the first curved surface 2011 is set as an outer convex surface, the second curved surface 301 is a matching inner concave surface; it should be noted here that the second curved surface 301 is similar to the first curved surface 2011, and can be a spherical surface, a cylindrical surface or an arc surface.

[0061] In an optional embodiment of the present invention, the second curved surface 301 can be formed together with the first gasket 300, for example, by casting or pouring; in another optional example of the present invention, the second curved surface 301 can also be obtained by secondary processing on a machine tool after the first gasket 300 is manufactured, for example, by removing a portion of the end face of the boom sleeve 201 by a milling machine or a grinder.

[0062] In an optional embodiment of the present invention, continue to refer to Figure 3 As shown, the cableway sling connection device further includes a locking member 400 , which is sleeved on the main shaft 101 of the rope gripper 100 and is located on the side of the first washer 300 away from the wire rope and facing away from the boom sleeve 201 .

[0063] Specifically, refer to Figure 3 As shown, in this embodiment of the present invention, the locking member 400 is located on the side of the boom sleeve 201 away from the cable grip 100. In some specific examples, the locking member 400 can be a locking bolt or a disc spring locking assembly, which is not limited in this embodiment of the present invention.

[0064] Reference Figure 3As shown, through the cooperation between the locking member 400 and the shoulder 102 of the rope gripper, the movement of the first gasket 300 and the boom sleeve 201 along the main shaft 101 of the rope gripper 100 can be limited, so that the first gasket 300 and the boom sleeve 201 can be in close contact with each other and axial pressure can be provided to the two, thereby generating friction between the boom sleeve 201 and the first gasket 300, which can hinder the axial rotation of the boom sleeve 201, reduce the swing angle of the sling and reduce the number of swings of the sling.

[0065] Specifically, in the embodiment of the present invention, the main shaft 101 of the rope grip 100 extends in the horizontal direction and passes through the first washer 300, the boom sleeve 201, the first washer 300, the locking piece 400 and the balance wheel 600 in the direction away from the main body of the rope grip 100. The first washer 300 and the boom sleeve 201 are locked by the locking piece 400 and the rope grip shoulder 102 and fit tightly together. When the boom sleeve 201 is affected by the eccentric force and the axis of the boom sleeve 201 deviates relative to the axis of the rope grip 100, the boom sleeve 201 The end face of the first curved surface 2011, that is, the first curved surface 2011 will be offset. Since the second curved surface 301 adapted to the first curved surface 2011 is a curved surface, the first curved surface 2011, that is, the end face of the boom sleeve 201 can rotate along the curved surface (referring to the figure, it can be understood that the first curved surface 2011 rotates around the x-axis). There will be no gap between the first curved surface 2011 and the second curved surface 301, and the effective contact area between the two will not change significantly, thereby maintaining the low pair of the first gasket 300 and the end face of the boom sleeve 201.

[0066] The present invention provides a cableway sling connection device, which comprises the following steps: setting the end surface of a boom sleeve 201 as a first curved surface 2011, and arranging first gaskets 300 at both ends of the boom sleeve 201; the first gasket 300 is sleeved on the main shaft 101 of the cable grip 100; the side of the first gasket 300 facing the boom sleeve 201 is set as a second curved surface 301, and the second curved surface 301 matches the first curved surface 2011; thus, after the boom sleeve 201 and the main shaft 101 of the cable grip 100 are locked by a locking member 400 arranged on the side of the first gasket 300 facing away from the boom sleeve 201; the first gasket 300 and the end surface of the boom sleeve 201 contact each other through the first curved surface 2011 and the second curved surface 301; thus, after the boom sleeve 201 and the main shaft 101 of the cable grip 100 are locked, the first gasket 300 and the end surface of the boom sleeve 201 are in contact with ... After the grip 100 and the sling (such as the car or basket of a cable car) are installed on the wire rope, the main shaft 101 of the grip 100 is slightly deflected under the action of the gravity of the sling. When the axis of the main shaft 101 and the axis of the boom sleeve 201 are not in a straight line (which can also be called deflected by a certain angle or not collinear), the end face of the boom sleeve 201 always maintains surface contact with the first gasket 300 through the first curved surface 2011 and the second curved surface 301. Compared with the related art, the kinematic pair between the end face of the boom sleeve 201 and the flat gasket 50 is converted from a high pair to a low pair, thereby reducing local wear between the boom sleeve 201 and the first gasket 300, effectively protecting the first gasket 300 from damage, and improving the safety of the cableway.

[0067] Figure 5 This is a structural schematic diagram of a first gasket in a cableway sling connection device provided by an embodiment of the present invention; Figure 6 yes Figure 5 Main view along direction A.

[0068] Based on the above embodiments, Figure 4 、 Figure 5 and Figure 6 As shown, in an optional embodiment of the present invention, the first curved surface 2011 is a concave spherical surface, and the second curved surface 301 matching it is a convex spherical surface; the formation method of the concave spherical surface and the convex spherical surface can refer to the formation method of the first curved surface 2011, and will not be repeated here.

[0069] In the embodiment of the invention, the first arc surface 2011 is set as a concave spherical surface, and the second arc surface 301 is set as a convex spherical surface, so that the first arc surface 2011 and the second arc surface 301 can be Figure 3 or Figure 4The x-axis, y-axis, or z-axis in the embodiment is used as the rotation axis for relative rotation. Furthermore, the effective contact area between the first curved surface 2011 and the second curved surface 301 does not change before and after the rotation. This ensures that even when the end face of the boom sleeve 201 deflects, the frictional effect between the boom sleeve 201 and the first gasket 300 remains unchanged. This ensures uniform transmission of friction between the boom sleeve 201 and the first gasket 300, reduces wear at the extrusion point, and improves the safety of the cableway sling connection device. Furthermore, compared to existing technologies, the contact area between the first gasket 300 and the end face of the boom sleeve 201 is increased, preventing the first gasket 300 from breaking due to localized pressure concentration.

[0070] Figure 7 1 is a structural diagram of a first gasket in a cableway sling connection device provided by an embodiment of the present invention. Figure 8 The first gasket along the cableway sling connection device provided by the embodiment of the present invention Figure 7 Main view in direction B.

[0071] On the basis of the above embodiments, in an optional embodiment of the present invention, the first arc surface 2011 may be an inner concave cylindrical surface, and the second arc surface 301 matched therewith may be an outer convex cylindrical surface. Figure 7 As shown, the thickness of the first gasket 300 on both sides along the vertical direction is smaller than the thickness in the middle. The middle portion of the first gasket 300 facing the boom sleeve 201 is convex to form an outward convex cylindrical surface. The formation of the inward concave cylindrical surface and the outward convex cylindrical surface can be referred to the formation of the first curved surface 2011 and will not be repeated here.

[0072] In an embodiment of the present invention, by setting the second curved surface 301 as an outward convex cylindrical surface, the thickness of the first gasket 300 on both sides along the vertical direction is made smaller than the thickness in the middle. In this way, the relative rotation of the first gasket 300 and the boom sleeve 201 around the z-axis and y-axis in the figure can be limited, so that the first gasket 300 and the boom sleeve 201 move in the circumferential direction in the same manner. Compared with the prior art, the wear of the first gasket 300 and the boom sleeve 201 caused by the relative rotation around the z-axis and y-axis in the figure is avoided.

[0073] On the basis of the above embodiments, in an optional embodiment of the present invention, as Figure 4 As shown, a limiting boss 2012 is provided on at least one of the first gasket 300 and the boom sleeve 201 , and a limiting groove 3011 is provided correspondingly on at least the other one of the first gasket 300 and the boom sleeve 201 .

[0074] It can be understood that when the first gasket 300 is in contact with the boom sleeve 201 , the limiting boss 2012 is inserted into the limiting groove 3011 to limit the circumferential rotation of the first gasket 300 and the boom sleeve 201 .

[0075] That is to say, referring to Figure 4 As shown, the limiting boss 2012 is provided in the limiting groove 3011, thereby limiting the relative rotation of the first gasket 300 and the suspension rod sleeve 201 around the y-axis. In the embodiment of the present invention, referring to Figure 4 As shown, the limiting boss 2012 is provided on the end surface of the suspension rod sleeve 201, and the limiting groove 3011 is provided on the side of the first gasket 300 facing the sleeve as a specific example for illustration.

[0076] It is understandable that in some optional examples of the embodiments of the present invention, the first gasket 300 may also have both a limiting boss 2012 and a limiting groove 3011, and the limiting groove 3011 and the limiting boss 2012 can be correspondingly provided on the boom sleeve 201.

[0077] In an embodiment of the present invention, the limiting boss 2012 can be formed integrally with the first gasket 300 or the boom sleeve 201, for example, by casting or pouring. The limiting boss 2012 can also be welded to the first gasket 300 or the boom sleeve 201 by welding after manufacturing is completed; the formation method of the limiting groove 3011 is similar to the first curved surface 2011, and can be formed integrally with the first gasket 300 or the boom sleeve 201 by casting, or can be obtained by removing a part of the end face of the first gasket 300 or the boom sleeve 201 by machine tool processing. It should be noted here that the limiting boss 2012 can also be obtained by processing the manufactured first gasket 300 or boom sleeve 201 on a machine tool, removing a part of the first gasket 300 or the boom sleeve 201, so that the limiting boss 2012 protrudes from the plane of the end face of the first gasket 300 or the boom sleeve 201.

[0078] In an embodiment of the present invention, a limiting boss 2012 is provided on at least one of the first gasket 300 or the boom sleeve 201, and a limiting groove 3011 is provided on at least the other of the first gasket 300 and the boom sleeve 201. In this way, when the first gasket 300 is in contact with the boom sleeve 201, the circumferential rotation of the first gasket 300 and the boom sleeve 201 can be limited by the cooperation between the limiting boss 2012 and the limiting groove 3011. In other words, the relative circumferential rotation of the first gasket 300 and the boom sleeve 201 is limited, so that the circumferential movement of the first gasket 300 and the boom sleeve 201 is consistent. Compared with the prior art, the wear of the first gasket 300 and the boom sleeve 201 due to inconsistent circumferential rotation is avoided, and the durability of the first gasket 300 and the boom sleeve 201 is improved.

[0079] In an optional example of an embodiment of the present invention, refer to Figure 4As shown, the limiting boss is arranged on the end surface of the suspension rod sleeve, and the limiting groove is arranged on the side of the first gasket facing the sleeve.

[0080] In the embodiment of the present invention, a limiting boss is provided on the end face of the boom sleeve, and a limiting groove is provided on the side of the first gasket facing the sleeve; in this way, the limiting boss and the limiting groove cooperate in the axial direction of the boom sleeve, thereby effectively reducing the space required for the boom sleeve and the first gasket to be occupied in the radial direction, and facilitating the assembly of the first gasket and the boom sleeve. Based on the above embodiments, in the optional embodiment of the present invention, continue to refer to Figure 4 As shown, there can be multiple limiting bosses 2012, and the multiple limiting bosses 2012 are arranged at intervals along the circumference of the boom sleeve 201.

[0081] It can be understood that the multiple limiting bosses 2012 can be on one of the end faces of the first gasket 300 or the boom sleeve 201, and correspondingly, the multiple limiting grooves 3011 are on the other one; the first gasket 300 can also have both limiting bosses 2012 and limiting grooves 3011, and correspondingly, the limiting grooves 3011 and limiting bosses 2012 can be set on the boom sleeve 201.

[0082] It should be noted that the spacing arrangement of the limiting bosses 2012 and the limiting grooves 3011 can be uniform or uneven. Figure 4 As shown, two limiting bosses 2012 are provided on the end surface of the boom sleeve 201 as a specific example for illustration.

[0083] In an embodiment of the present invention, a plurality of limiting bosses 2012 are arranged circumferentially at intervals along the boom sleeve 201. Thus, through the cooperation of the plurality of limiting bosses 2012 and the limiting grooves 3011, the first gasket 300 and the boom sleeve 201 can be prevented from relative rotation in the circumferential direction, thereby avoiding wear between the two due to relative rotation in the circumferential direction, improving the durability of the first gasket 300 and the boom sleeve 201, and saving the cost of use.

[0084] On the basis of the above embodiments, in the optional embodiment of the present invention, referring to Figure 3 and Figure 4 As shown, the cableway sling connection device further includes a second gasket 500 , which is passed through the main shaft 101 of the rope grip 100 and is arranged on a side of the first gasket 300 facing away from the boom sleeve 201 .

[0085] It can be understood that there is a second gasket 500 on each side of the two first gaskets 300 facing away from the boom sleeve 201 , and the second gasket 500 is in contact with the first gasket 300 .

[0086] Continue to refer to Figure 3 As shown, specifically, on the side of the boom sleeve 201 facing away from the cable grip 100, the second gasket 500 is located between the first gasket 300 and the locking member 400, and on the side of the boom sleeve 201 close to the cable grip 100, the second gasket 500 is located between the first gasket 300 and the cable grip shoulder 102.

[0087] Specifically, the second gasket 500 may refer to the plane friction plate in the prior art, which will not be described in detail in the embodiment of the present invention.

[0088] In an optional example of the present invention, referring to Figure 3 As shown, the main shaft 101 of the cable grip 100 extends along the side away from the main body of the cable grip 100 and passes through the second gasket 500, the first gasket 300, the boom sleeve 201, the first gasket 300, the second gasket 500, the locking member 400 and the balance wheel 600 in sequence. Through the action of the locking member 400 and the cable grip shoulder 102, the cable grip 100 provides a locking force so that the first gasket 300, the second gasket 500 and the boom sleeve 201 fit tightly together. Together, the contact surface between the first gasket 300 and the boom sleeve 201 is an arcuate surface, namely the first arcuate surface 2011 and the second arcuate surface 301. The first arcuate surface 2011 and the second arcuate surface 301 are matching spherical surfaces. The first arcuate surface 2011 and the second arcuate surface 301 are provided with corresponding limiting bosses 2012 and limiting grooves 3011. The side of the first gasket 300 facing away from the boom sleeve 201 is tightly fitted with the second gasket 500.

[0089] When the end face of the boom sleeve 201 deviates due to the influence of the eccentric force, the end face of the boom sleeve 201 can be around the end face of the boom sleeve 201 due to the fit between the first curved surface 2011 and the second curved surface 301. Figure 3 , it is easy to understand that although the end face of the boom sleeve 201 and the side of the first gasket 300 facing the boom sleeve 201 have rotated relative to each other, since the contact surfaces of the two are arc-shaped surfaces, the uniform transmission of the friction pair between the end face of the boom sleeve 201 and the first gasket 300 will not be changed; at the same time, because of the design of the limiting boss 2012 and the limiting groove 3011, the end face of the boom sleeve 201 and the first gasket 300 are limited. Figure 3 The rotation around the y-axis and z-axis reduces unnecessary wear between the two. It is understandable that the boom sleeve 201 and the first washer 300 do not rotate relative to each other in the circumferential direction. Circumferential relative rotation only occurs between the first washer 300 and the second washer 500. Therefore, wear primarily occurs between the first washer 300 and the second washer 500, protecting the end face of the boom sleeve 201.

[0090] In an embodiment of the present invention, a second gasket 500 is provided on the side of the first gasket 300 facing away from the boom sleeve 201. In this way, friction is generated between the first gasket 300 and the second gasket 500 due to contact between the two. This friction is further transmitted to the boom sleeve 201 through the first gasket 300 as resistance. Since the contact surface between the first gasket 300 and the boom sleeve 201 is an arc-shaped surface, the uniform transmission of the friction pair between the end face of the boom sleeve 201 and the first gasket 300 will not be changed, and the uniform transmission of the friction pair between the first gasket 300 and the second gasket 500 will not be changed. When the sling accelerates or decelerates, the swing amplitude of the sling is reduced and the number of swings of the sling is reduced, thereby improving the safety and stability of the cableway sling connection device.

[0091] Based on the above embodiments, in an optional embodiment of the present invention, one of the first gasket 300 and the second gasket 500 is provided with a receiving groove 302, and at least a portion of the other of the first gasket 300 and the second gasket 500 is embedded in the receiving groove 302. In this embodiment of the present invention, the receiving groove 302 is provided on the side of the first gasket 300 facing away from the boom sleeve 201.

[0092] Specifically, refer to Figure 4 As shown, the first gasket 300 has a circular receiving groove 302 on the side facing the second gasket 500, and the receiving groove 302 is suitable for allowing the second gasket 500 to be embedded in the first gasket 300. In other words, the first gasket 300 can form a semi-enclosed structure to wrap the second gasket 500. When the locking member 400 cooperates with the cable grip shoulder 102 to generate a locking force, the locking force can cause the second gasket 500 to be embedded in the receiving groove 302 of the first gasket 300; in an optional example of the present invention, it can be set The hardness of the second gasket 500 is less than that of the first gasket 300. It is easy to understand that when wear occurs between the second gasket 500 and the first gasket 300, the wear occurs first on the second gasket 500. As the usage time increases, when the second gasket 500 breaks due to wear, due to the presence of the locking piece 400 and the accommodating groove 302 on the first gasket 300, the second gasket 500 will not fall off, and the second gasket 500 can continue to generate friction with the first gasket 300 and continue to play its role.

[0093] In the embodiment of the present invention, a receiving groove 302 is provided on one of the first gasket 300 and the second gasket 500, and at least a portion of the other gasket is embedded in the receiving groove 302. In this way, when one of the gaskets in the receiving groove 302 is broken, the broken gasket is located in the receiving groove 302 of the other gasket, thereby preventing the broken gasket from falling, thereby improving the safety of the cableway sling connection device.

[0094] An embodiment of the present invention further provides a cable car, comprising the cableway hoist connection device described in any optional example of the aforementioned embodiments of the present invention.
