Description

Technical Field

[0001] This invention relates to the field of cableway system technology, and in particular to a device for detecting the anti-slip force of a detachment grip. Background Technology

[0002] The function of a detachable grip is to hold the wire rope securely during gondola operation, allowing the gondola to travel smoothly at high altitudes carrying passengers. It converts the spring force at the rear of the detachable grip or the torque of the internal torsion bar into a clamping force on the wire rope. The friction generated after clamping the wire rope secures the gondola to the rope, preventing it from slipping or detaching. The force that prevents the passenger-carrying equipment from slipping due to factors such as track gradient, equipment sway, and starting / braking inertia is called the anti-slip force. Anti-slip force is a crucial data point in cableway operation, closely linked to the safety of passengers, and is one of the essential items to check during inspection and maintenance. To ensure gondola safety, the detachable grip and rope must always be firmly attached; that is, the detachable grip must have a sufficiently large anti-slip force. Therefore, the detachable grip needs to undergo anti-slip force testing.

[0003] Existing anti-slip force testing devices for detachable grips are generally divided into two categories. The first type uses the tension of the wire rope to complete the anti-slip force test. However, this method is cumbersome to install, and if the distance between the detachable grip and the testing device is far, excessive system pressure needs to be released during measurement, resulting in a long measurement time. For cableway tensioning systems with complex lines and high stress, disassembly is difficult after measurement, further extending the measurement time. The second type uses a small manual hydraulic pump to pressurize and test the anti-slip force. The thrust generated by the manual pump on the jaws is converted into clamping force through a lever, and the pressure value displayed on the hydraulic gauge on the testing device is converted into the corresponding anti-slip force value. This method requires a high level of skill from the installer and operator. Improper operation often leads to problems such as the clamping block becoming completely jammed, the testing device being unable to be installed or removed, and insufficient oil in the manual pump cylinder.

[0004] Moreover, the two anti-slip force testing methods mentioned above are only applicable to cableway equipment designed by the same unit, and their measurement versatility is poor. Summary of the Invention

[0058] To make the objectives, technical solutions, and advantages of this invention clearer, the technical solutions of this invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some, not all, of the embodiments of this invention. All other embodiments obtained by those skilled in the art based on the embodiments of this invention without creative effort are within the scope of protection of this invention.

[0059] In the description of the embodiments of the present invention, it should be noted that the terms "center," "longitudinal," "lateral," "upper," "lower," "front," "rear," "left," "right," "vertical," "horizontal," "top," "bottom," "inner," and "outer," etc., indicate the orientation or positional relationship based on the orientation or positional relationship shown in the accompanying drawings. They are only for the convenience of describing the embodiments of the present invention and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limitations on the embodiments of the present invention. In addition, the terms "first," "second," and "third" are used for descriptive purposes only and should not be construed as indicating or implying relative importance.

[0060] The following is combined Figures 1 to 5 The present invention describes the anti-slip force detection device for the detachment gripper.

[0061] like Figure 1 As shown, the detachable gripper 1 is a schematic structure. The detachable gripper 1 has a guide wing 7 and a clamp 8, which are fixedly connected. The extension direction of the guide wing 7 is the same as the extension direction of the wire rope 2. The clamp 8 is used to clamp the wire rope 2.

[0062] The anti-slip force detection device for the detachment gripper provided in this embodiment of the invention includes a force measuring mechanism 3, a clamping and fixing mechanism 4, a connecting rod mechanism 5, and a pressure applying mechanism 6.

[0063] The force measuring mechanism 3 contacts the outer surface of the jaws of the clamping clamp 8, with the force measuring position close to the jaws for accurate measurement. The force measuring mechanism 3 is also used to collect and read the anti-slip force test data. The clamping and fixing mechanism 4 clamps the wire rope 2, forming a fixed measuring end. This mechanism provides a fixed measuring end that does not move during the anti-slip force test and ensures that the anti-slip force it can withstand is greater than the maximum anti-slip force of the clamping clamp. One end of the linkage mechanism 5 is connected to the force measuring mechanism 3, and the other end is connected to the clamping and fixing mechanism 4. The linkage mechanism 5 connects the force measuring mechanism 3 and the clamping and fixing mechanism 4 together, enabling axial positioning of the clamping and fixing mechanism 4. The pressurizing mechanism 6 can act on the force measuring mechanism 3. The pressurizing mechanism 6 is used to generate pressure and transmit the pressure to the force measuring mechanism 3. The force measuring mechanism 3 displays the pressure value given by the pressurizing mechanism 6. When the pressure value reaches the anti-slip force requirement set by the release gripper 1, the release gripper 1 and the wire rope 2 do not move relative to each other, which proves that the design of the release gripper 1 meets the requirements.

[0064] The anti-slip force testing device for detachable grips provided by this invention solves the problems of incompatibility of anti-slip force testing tools between detachable cableway equipment designed by different units installed in scenic areas and ski resorts, and the problem of operators being unfamiliar with the equipment during measurement, leading to the inability to resume operation. Moreover, the anti-slip force testing device provided by this invention does not require the detachable grip 1 to be removed from the gondola during use, thus avoiding safety hazards. In addition, by setting up the clamping and fixing mechanism 4, it is not necessary to use the platform as a fixed end for measurement, making the operation convenient and quick.

[0065] like Figure 2As shown, in a feasible embodiment of the present invention, the force measuring mechanism 3 includes a pair of clamping plates 31, a base plate 32, a pair of clamping claws 33, and a pair of force gauges 34. The pair of clamping plates 31 are arranged opposite to each other on both sides of the wire rope 2, and each clamping plate 31 has a first groove 311 for connecting the linkage mechanism 5 on its side. The tension generated by the linkage mechanism 5 is transmitted through the clamping plates 31, and the tension is transmitted to the force gauges 34 through the center of the clamping plates 31. The force gauges 34 are pressed to measure the anti-slip force data. Transmitting the tension through the center can reduce the required hydraulic cylinder tension by half and reduce the volume of the hydraulic cylinder. One end of the clamping claw 33 is in contact with the release gripper 1, and the top clamping claw is in contact with the outer surface of the release gripper jaw. A clamping shaft 37 is fixedly provided on the outer side of each clamping claw 33. The axis of the clamping shaft 37 is perpendicular to the axis of the wire rope, and the clamping shaft 37 is in contact with and limited by the clamping plate 31. The purpose of the clamping shaft 37 is twofold. Firstly, by fitting the clamping plate 31 against the clamping shaft 37, the clamping plate 31 is perpendicular to the wire rope. This ensures that when the pressure mechanism 6 transmits force, all the force is transferred to the force gauge 34. Conversely, if the clamping plate 31 is not perpendicular to the wire rope, the force gauge only receives a component of the force from the pressure mechanism 6. In other words, it saves the tension of the pressure mechanism 6, ensuring that the tension of the pressure mechanism 6 is always perpendicular to the force gauge 34 during measurement. Secondly, the clamping shaft 37 provides lateral positioning for the clamping and fixing mechanism 4. Since the initial lateral position of the clamping and fixing mechanism 4 is uncertain, its position can only be determined after the clamping plate 31 and the clamping shaft 37 are fitted together and connected to the first groove 311 via the linkage mechanism 5. The claw 33 not only ensures that the force gauge 34 is subjected to force parallel to the wire rope, but it can also be adjusted according to the shape of the outer clamp of the release gripper, ensuring suitability for measuring the anti-slip force of most release grippers. A pair of force gauges 34 are respectively set on the side of the jaws 33 near the release gripper 1; the force gauges 34 are used to collect and read the anti-slip force test data; the pair of force gauges 34 measure at the same time, the data are close, and they are compared with each other to form a data comparison, which can better reflect the force on both sides of the release gripper jaws, and when one of the force gauges 34 is damaged, it can be detected in time without affecting the measurement data results.

[0066] It should be noted that the inner surface of the jaws of the release gripper 1 refers to the contact surface between the gripper 8 of the release gripper 1 and the wire rope 2, while the outer surface of the jaws refers to the outer surface of the gripper 8 opposite to the inner surface of the jaws.

[0067] In one feasible embodiment of the present invention, the force gauge 34 can be detachably connected to the claw 33, and the force gauge 34 can also be detachably connected to the clamping plate 31. When the entire detachment grip anti-slip force detection device is working, the force gauge 34 is connected to the claw 33 or the clamping plate 31 to ensure that the clamping plate 31, the base plate 32, the claw 33, and the force gauge 34 are relatively fixed during operation and do not move relative to each other. When the entire detachment grip anti-slip force detection device is not working, the force gauge 34 can be disassembled and stored to prevent damage to the force gauge 34.

[0068] like Figure 2 As shown, in a specific connection, the card plate 31 can be installed and used through the connecting post 35. In order to ensure the effectiveness of the connection between the card plate 31 and the claw 33, a limit pin 36 is also provided perpendicular to the connecting post 35.

[0069] It should be noted that the force gauge 34 is usually housed inside a mounting housing to protect it from damage.

[0070] like Figure 3 As shown, in a feasible embodiment of the present invention, the clamping and fixing mechanism 4 includes a support frame 41, an upper clamping block 42, a lower clamping block 43, a handle 44, and a transmission assembly 45. The support frame 41 provides support for the upper clamping block 42 and the lower clamping block 43. The upper clamping block 42 is disposed on the support frame 41, and the bottom of the upper clamping block 42 has a semi-circular groove, that is, the bottom surface of the upper clamping block 42 is an arc-shaped surface, and the shape of the bottom surface of the upper clamping block 42 is adapted to the steel wire rope 2. The lower clamping block 43 is elliptically disposed on the support frame 41, and the top of the lower clamping block 43 has an arc-shaped groove, that is, the top surface of the lower clamping block 43 is an arc-shaped surface, and the shape of the top surface of the lower clamping block 43 is adapted to the steel wire rope. In other words, the upper clamping block 42 and the lower clamping block 43 together clamp the steel wire rope 2, and the shapes of the opposite surfaces of the upper clamping block 42 and the lower clamping block 43 to the steel wire rope 2 match the shape of the steel wire rope 2. The handle 44 is used to input the tightening force; the transmission component 45 is disposed between the handle 44 and the lower clamp 43, and the transmission component 45 is used to convert the shaking of the handle 44 into the lifting and lowering of the lower clamp 43.

[0071] In this embodiment of the invention, the wire rope 2 is fixed by mechanical clamping, which is different from the traditional bolt connection method. During the operation, a torque wrench is not used to directly tighten the bolt. Instead, the small torque at the handle 44 is converted into the required large torque by the transmission component 45 to complete the clamping or loosening of the measuring and fixing end and the wire rope 2.

[0072] like Figure 4 and Figure 5As shown, specifically, the transmission assembly 45 includes an input shaft 451, a multi-stage gear reducer 452, and an output gear bolt 453. The input shaft 451 is connected to the handle 44. The multi-stage gear reducer 452 has an input end and an output end, with the input end connected to the input shaft 451. The output gear bolt 453 is threadedly connected to the lower clamping block 43 and is also connected to the output end. By utilizing the multi-stage reduction and torque increase function of the multi-stage gear reducer 452, the large torque required to tighten the large-diameter bolt is converted into a small torque that can be achieved manually, thereby completing the clamping or loosening of the measuring fixed end and the wire rope 2.

[0073] Furthermore, the multi-stage gear reducer 452 is configured as a three-stage reduction gear with a transmission ratio greater than 19. The torque input from the handle 44 is transmitted to the output gear bolt 453 via the multi-stage gear transmission, completing the screwing in and out of the output gear bolt 453. The multi-stage gear reducer 452 may include rolling bearings, involute spur gears, and straight bevel gears. See the internal gear meshing diagram for details. Figure 4 .

[0074] like Figure 5 As shown, the multi-stage gear reducer 452 includes a first gear Z1, a second gear Z2, a third gear Z3, a fourth gear Z4, a fifth gear Z5, a sixth gear Z6, a seventh gear Z7, an eighth gear Z8, and a ninth gear Z9. The first gear Z1, second gear Z2, and third gear Z3 are all spur gears; the fourth gear Z4 and fifth gear Z5 are bevel gears; and the sixth gear Z6, seventh gear Z7, eighth gear Z8, and ninth gear Z9 are all cylindrical gears. The first gear Z1 is mounted on the output gear bolt 453. There can be two first gears Z1. The first gear Z1 meshes simultaneously with the second gear Z2, the second gear Z2 meshes with the third gear Z3, the fourth gear Z4 is coaxial with the third gear Z3, and the fifth gear Z5 meshes with the fourth gear Z4, thus achieving a change in the direction of power transmission. The sixth gear Z6 and the fifth gear Z5 are coaxial, and the diameter of the sixth gear Z6 is larger than the diameter of the fifth gear Z5. The sixth gear Z6 meshes with the seventh gear Z7, and the diameter of the seventh gear Z7 is smaller than the diameter of the sixth gear Z6. The eighth gear Z8 is coaxial with the seventh gear Z7, and the diameter of the eighth gear Z8 is larger than the diameter of the seventh gear Z7. The ninth gear Z9 is coaxial with the eighth gear Z8, and the diameter of the ninth gear Z9 is smaller than the diameter of the eighth gear Z8. The ninth gear Z9 is mounted on the input shaft 451 and is used to transmit power from the handle 44.

[0075] The input shaft 451 converts the small torque and high speed generated by manual operation at the handle 44 into a large torque and low speed through the multi-stage gear reducer 452, thus completing the clamping of the clamping and fixing mechanism 4. When in use, the multi-stage gear reducer 452 only transmits the torque from the input handle 44 to the two output gear bolts 453 at the output end via multi-stage gear transmission, completing the screwing in and out of the output gear bolts 453.

[0076] like Figure 3 As shown, in a feasible embodiment of the present invention, the upper clamping block 42 is detachably connected to the support frame 41. The support frame 41 is integrally formed and includes a first side plate 411, a second side plate 412, and a support plate 414. The first side plate 411 and the second side plate 412 are arranged opposite to each other, and there is a space between the first side plate 411 and the second side plate 412 to accommodate the upper clamping block 42 and the lower clamping block 43. The first side plate 411 and the second side plate 412 are provided with a first sliding groove 413 to facilitate the installation of the upper clamping block 42 and a second sliding groove 417 to facilitate the up and down movement of the lower clamping block 43. The first sliding groove 413 is L-shaped and includes a vertical sliding groove and a horizontal sliding groove, and the vertical sliding groove and the horizontal sliding groove are connected. The support plate 414 is disposed between the first side plate 411 and the second side plate 412, and the output gear bolt 453 passes through the support plate 414 and is threadedly connected to the lower clamping block 43.

[0077] like Figure 3 As shown, in a feasible embodiment of the present invention, the clamping and fixing mechanism 4 further includes a pair of spring positioning structures 46, which are respectively disposed on the first side plate 411 and the second side plate 412. The sides of the first side plate 411 and the second side plate 412 are provided with second grooves 416 for connecting the linkage mechanism 5. The spring positioning structures 46 can rise and fall with the installation of the upper clamping block 42 to realize the upper clamping block 42 being clamped with the first side plate 411 or the second side plate 412. The upper clamping block 42 has sliding rods 421 on both sides.

[0078] like Figure 3 As shown, specifically, a third sliding groove 415 is provided on both the first side plate 411 and the second side plate 412. The sliding rod 421 can slide up and down along the third sliding groove 415. The spring positioning structure 46 includes a connecting plate 461, an elastic element, a positioning pin 462, and a locking block 463. The connecting plate 461 is horizontally arranged in the first side plate 411. The top of the elastic element is connected to the connecting plate 461. The positioning pin 462 is connected to the other end of the elastic element. The locking block 463 is connected to the positioning pin 462. The positioning pin 462 and the locking block 463 can slide up and down in the third sliding groove 415, and the locking block 463 is used to lock and fix the upper clamping block 42 to the first side plate 411.

[0079] During the installation of the upper clamping block 42, as it slides down the first slide groove 413, it contacts the locking block 463 when moving from the vertical slide groove to the horizontal slide groove. The compression elastic element contracts, and the locking block 463 and the positioning pin 462 move upwards with the compression of the elastic element. The upper clamping block 42 continues to move horizontally within the horizontal slide groove to its end. At this point, the locking block 463 and the positioning pin 462 extend under the stretching action of the elastic element. The locking block 463 limits the sliding rod 421, and the sliding rod 421 is fixedly connected to the upper clamping block 42, thus achieving the locking and fixing of the upper clamping block 42. When the upper clamping block 42 is stationary, the locking block 463 remains within the horizontal slide groove.

[0080] It should be noted that during installation, simply slide the sliding rod 421 of the upper clamping block 42 into the inner side of the positioning pin 462 along the first slide groove 413 to complete the longitudinal positioning of the clamping and fixing mechanism 4. The bottom of the locking block 463 is set as an arc shape, and the side of the end near the horizontal slide groove is set as a plane; and the arc diameter of the locking block 463 is larger than the diameter of the sliding rod 421, and the contact method is arc surface contact. Therefore, there is no need to manually operate the positioning pin 462. When the upper clamping block 42 passes through the spring positioning structure 46, the positioning pin 462 can automatically spring up. After it is in place, the positioning pin 462 automatically resets and uses the plane side of the locking block 463 to lock the sliding rod 421, preventing the upper clamping block 42 from sliding or loosening during measurement. When disassembling the clamping and fixing mechanism 4, first operate the handle 44 to loosen the lower clamping block 43, and slide the positioning pin 462 upward while the sliding rod slides out along the first sliding groove 413, thereby realizing the disassembly of the upper clamping block 42 and the support frame 41, and thus completing the disassembly of the clamping and fixing mechanism 4.

[0081] The main motion modes of the clamping and fixing mechanism 4 are rotational and vertical motion. When the input handle 44 is manually cranked, the longitudinal rotation of the handle 44 is converted into the lateral rotation of the output gear bolt 453 after deceleration, reversal, and torque enhancement by the gear reducer. Through the threaded connection between the output gear bolt 453 and the support plate 414, the rotational motion of the output gear bolt 453 is converted into longitudinal movement, thus completing the clamping and loosening of the wire rope.

[0082] like Figure 1As shown, in a feasible embodiment of the present invention, the pressurizing mechanism 6 includes a hydraulic oil pump 61, a hydraulic cylinder 62, and a hydraulic rod 63. The hydraulic oil pump 61 provides power; the hydraulic cylinder 62 is connected to the hydraulic oil pump 61, and one end of the hydraulic cylinder 62 is connected to the clamping and fixing mechanism 4; one end of the hydraulic rod 63 is telescopically connected to the hydraulic cylinder 62, and the other end is connected to the force measuring mechanism 3. When the hydraulic oil pump 61 is manually operated, the hydraulic rod 63 shortens, generating a pulling force on the detachable cable gripper. The value displayed on the force gauge 34 is read. When the design value is reached, the pressurization is stopped, and the measurement is completed. If the detachable cable gripper 1 and the wire rope 2 do not slip, it proves that the production of the detachable cable gripper 1 meets the requirements.

[0083] The selection of the force measurement position is very important. An incorrect selection of the force measurement position will result in a discrepancy between the measured result and the actual tension borne by the jaws of the release gripper, resulting in inaccurate measurement data. The measurement position selected in this invention is on the surface of the jaws of the release gripper 1. This position can accurately reflect the anti-slip force value borne by the jaws.

[0084] When the hydraulic rod 63 retracts, it generates a pulling force on the outer clamp of the release sling. To prevent the measuring plane from tilting due to asymmetrical force distribution during measurement, a mounting bracket 52 is installed between the hydraulic rod 63 and the clamping plate 31. One end of the mounting bracket 52 is hinged to the hydraulic rod 63, and the other end is hooked to the clamping plate 31 to ensure that the measuring plane is always in close contact with the outer surface of the outer clamp. The linkage mechanism 5 converts the pulling force generated by the hydraulic cylinder 62 into simultaneous force distribution on both the upper and lower sides, with the force measuring position at the center of the clamping plate 31. This configuration ensures that the force measuring device does not tilt during measurement, the force direction is perpendicular to the measuring plane, and it also reduces the pulling force of the hydraulic cylinder 62, thereby reducing the size of the hydraulic cylinder and the overall weight.

[0085] The method of using the anti-slip force detection device for the detachment harness provided by this invention is as follows:

[0086] Stop the gondola 1m from the platform exit or in the middle of the support operating platform connected to the platform. Hold the force measuring mechanism 3 and clamp the claws 33 of the force measuring mechanism 3 on the front and back sides of the outer clamp of the detachment cable grabber, so that the force gauge 34 is in close contact with the small plane after the outer clamp and the wire rope are clamped.

[0087] Hold the clamping and fixing mechanism 4, with the lower clamping block 43 pressed against the bottom surface of the wire rope 2, and install the upper clamping block 42 along the first slide groove 413 onto the inner side of the locking block 463.

[0088] Hold the linkage mechanism 5 and connect one end of the linkage mechanism 5 to the groove of the clamping plate 31, and the other end to the groove above the clamping and fixing mechanism 4; adjust the position of the clamping and fixing mechanism 4 back and forth to ensure that the short shafts 51 at both ends of the linkage mechanism 5 are inserted into the grooves, and at the same time, the upper end of the clamping plate 31 of the linkage mechanism is in close contact with the cylindrical positioning block on the claw 33. At this time, the clamping plate 31 is perpendicular to the wire rope 2, and the clamping and fixing mechanism 4 and the linkage mechanism 5 are positioned.

[0089] Keep all mechanisms in place, and manually crank handle 44 to clamp the lower clamp 43 with the wire rope until it can no longer be cranked by hand. At this point, the clamping and fixing mechanism 4 is installed and the fixed end is formed.

[0090] Secure the front and rear mounting shafts of the pressurizing mechanism 6 to the grooves below the clamping plate 31, the first side plate 411, and the second side plate 412, respectively. Connect the small manual pump, close the pressure relief valve, and the mechanical device is installed. Begin testing.

[0091] When pressure is applied through the pressurizing mechanism 6, the hydraulic rod 63 moves towards the hydraulic cylinder 62. Since the force gauge 34 is in contact with the detachment gripper 1 and the clamping plate 31 is perpendicular to the wire rope 2, the tension is transmitted to the force gauge 34 when the hydraulic rod 63 retracts. If the reading of the force gauge 34 is greater than or equal to the design value of the anti-slip force of the detachment gripper 1, and the detachment gripper 1 has not undergone relative displacement with the wire rope 2, then it proves that the detachment gripper 1 meets the design requirements. Conversely, if the reading of the force gauge 34 is equal to or close to the design value of the anti-slip force of the detachment gripper 1, and the detachment gripper 1 has undergone relative displacement with the wire rope 2, then it proves that the detachment gripper 1 does not meet the design requirements.

[0092] The anti-slip force detection device for the detachment gripper provided by this invention is easy and quick to install, and each component can be equipped with a handle for easy handling. When using it, the operator can stand on the top of the gondola or the support operating platform to install each part with the jaws of the detachment gripper 1 and the wire rope 2, making the operation safer. When not in use, each component can be disassembled and stored, reducing the floor space occupied.
