Description

Technical Field

[0001] The invention relates to the technical field of traction wheels, in particular to an anti-skid traction device for a steel wire rope on an elevator traction wheel. Background Art

[0002] The traction sheave is the rope sheave on the traction machine, also called the traction rope sheave or driving rope sheave. It is the device for transmitting traction power of the elevator. It transmits power by the friction between the traction wire rope and the rope groove on the traction wheel rim. Therefore, the traction sheave must bear the total weight of the elevator car, load and counterweight.

[0003] In the prior art, a patent document with publication number CN210710271 U discloses an anti-slip traction wheel for an elevator, comprising a wheel disc, a retaining ring, a rim A, a rim B and a rim C, wherein two retaining rings are symmetrically limited on the inner sides of the left and right ends of the wheel disc, and rim A, rim B and rim C are arranged between the two retaining rings from left to right in sequence, the left end of the rim A is fixedly connected to one of the retaining rings by a plurality of screws and nuts, and the right end of the rim C is fixedly connected to the other retaining ring by a plurality of screws and nuts.

[0004] The above-mentioned traction wheel makes reasonable improvements to the structure of the existing traction wheel, so that the severely worn rim can be replaced without replacing the entire traction wheel, which not only reduces the production cost but also facilitates maintenance personnel to grasp the degree of wear of the rim. However, when the above-mentioned traction wheel is working, it is not convenient to effectively improve the anti-skid traction effect of the wire rope on the traction wheel through the reciprocating tensioning, multi-effect and multi-point traction methods of the wire rope. Based on this, the present invention provides an anti-skid traction device for wire rope on an elevator traction wheel to solve the problems raised in the above-mentioned background technology. Summary of the invention

[0005] The present invention aims at the technical problems existing in the prior art and provides an anti-skid traction device for wire rope on an elevator traction sheave to solve the problem that when the existing traction sheave is working, it is not convenient to effectively improve the anti-skid traction effect of the wire rope on the traction sheave through the reciprocating tensioning, multi-effect and multi-point traction methods of the wire rope.

[0006] The technical solution of the present invention to solve the above technical problems is as follows: an anti-slip traction device for a steel wire rope on an elevator traction wheel, comprising a fixing frame, and also comprising:

[0007] The traction wheel is rotatably connected to the fixed frame, the fixed frame is provided with a transmission module, the traction wheel is driven by the transmission module, the transmission module is transmission-connected with an inner bevel gear ring, and a group of steel wire ropes are provided on the outer side of the traction wheel;

[0008] A group of traction modules distributed in a circumferential array and installed in the traction wheel, each of the traction modules includes an active slider and a driven slider slidably connected to the traction wheel, a traction wheel is rotatably connected between the active slider and the driven slider, and a guide module linked to the inner bevel gear ring is installed on the active slider;

[0009] The reciprocating expansion mechanism is used to elastically change the layout position of the active slider on the traction wheel and reciprocately change the friction between the traction wheel and the wire rope;

[0010] Two symmetrically arranged tensioning frames, the inner walls of the two tensioning frames are rotatably connected with tensioning wheels;

[0011] The reciprocating tensioning component is used to reciprocately change the distance between the two tensioning frames.

[0012] The beneficial effects of the present invention are:

[0013] 1. In the present invention, when the traction operation is in progress, the worm motor outputs the rotation speed at the set power. After the worm motor outputs the rotation speed, the traction wheel and the traction wheel revolve at the set speed on the one hand, and the traction wheel spins at the set speed on the other hand, and the rotation speed and rotation direction of the traction wheel and the traction wheel are the same. Through the synchronous multi-point multi-power traction structure setting of the traction wheel and the traction wheel for the wire rope, on the one hand, the traction force on the wire rope can be effectively increased, and on the other hand, the friction contact area and friction strength between the wire rope and the traction wheel and the traction wheel can be effectively increased, thereby effectively improving the anti-slip effect of the wire rope.

[0014] 2. In the present invention, when the worm motor outputs the speed, the upper gear shaft is driven. After the upper gear shaft is driven, the transmission connection setting between the semi-transmission gear and the first gear plate and the setting of the first elastic pressure member enable the active pressure frame to reciprocate within the set stroke. When the active pressure frame moves back and forth within the set stroke, the positions of the elastic pressure frame and the inner pressure ring are reciprocated. After the position of the inner pressure ring is reciprocated, the position of the active slider on the traction wheel is reciprocated through the setting of the connecting frame, and the distance between the active slider and the axis of the traction wheel is reciprocated. By increasing the distance between the active slider and the traction wheel, the friction between the traction wheel and the wire rope is reciprocated and increased, thereby effectively improving the anti-skid effect between the traction wheel and the wire rope, thereby improving the stability of the wire rope during operation.

[0015] 3. In the present invention, after the worm motor outputs the rotation speed, the semi-transmission bevel gear and the second elastic pressure member are set so that the lower gear shaft can reciprocate and reverse within the set stroke. After the lower gear shaft reciprocates and reverses within the set period, the distance between the two tensioning frames is reciprocated, and then the friction between the tensioning wheel and the wire rope is reciprocated. The reciprocating change of the friction between the tensioning wheel and the wire rope effectively improves the anti-skid effect between the traction wheel and the wire rope.

[0016] 4. In the present invention, when the worm motor is working, the pump body works periodically for a specified period. During the working period of the pump body, the oil distribution pipe delivers asphalt oil to the surface of the wire rope, thereby increasing the friction between the wire rope and the tensioning wheel, the traction wheel and the guide wheel through external force.

[0017] Based on the above technical solution, the present invention can also be improved as follows.

[0018] Furthermore, the transmission module includes a worm motor fixed on a fixed frame and an inner rotating shaft arranged at the axis position of the traction large wheel, an outer rotating shaft is rotatably sleeved on the inner rotating shaft, the outer rotating shaft is fixedly connected to the inner bevel gear ring, an active bevel gear is fixedly installed on the output shaft end of the worm motor, a first bevel gear is installed on both the outer rotating shaft and the inner bevel gear ring, and the two first bevel gears are respectively arranged on both sides of the active bevel gear.

[0019] The beneficial effect of adopting the above further scheme is that when the traction operation is carried out, the worm motor outputs the speed at the set power. After the worm motor outputs the speed, the traction large wheel and the traction small wheel revolve at the set speed on the one hand, and the traction small wheel spins at the set speed on the other hand, and the speed and rotation direction of the traction large wheel and the traction small wheel are the same;

[0020] By setting up a synchronous multi-point and multi-power traction structure for the wire rope through the traction large wheel and the traction small wheel, on the one hand, the traction force on the wire rope can be effectively increased, and on the other hand, the friction contact area and friction strength between the wire rope and the traction large wheel and the traction small wheel can be effectively increased, thereby effectively improving the anti-slip effect of the wire rope.

[0021] Furthermore, the guide module includes a hollow shaft rotatably connected to the active slider and a solid shaft rotatably connected to the traction large wheel. The bottom end of the solid shaft is fixedly installed with a linkage bevel gear that is transmission-connected to the inner bevel gear ring. The interior of the hollow shaft is fixedly provided with an axis groove that is open at both ends and is slidably connected to the solid shaft. Differential bevel gears are installed on the hollow shaft and the traction small wheel, and the two differential bevel gears are meshed with each other.

[0022] Furthermore, the cross sections of the shaft groove and the solid shaft are both regular polygons, and the axis of the solid shaft is perpendicular to the axis of the traction large wheel.

[0023] The beneficial effect of adopting the above further scheme is that when the wire rope is being pulled, the solid shaft is driven by the inner bevel gear ring. After the solid shaft is driven by the inner bevel gear ring, the traction wheel can spin at a set speed. Through the regular polygonal cross-section of the shaft groove and the solid shaft, the hollow shaft can continuously drive the solid shaft during the change of the position of the active slider.

[0024] Furthermore, the reciprocating expansion support mechanism includes an active pressure frame, an elastic pressure frame, an inner pressure ring and an upper gear shaft rotatably connected to the fixed frame, the top end of the upper gear shaft is fixedly installed with an upper bevel tooth, the upper bevel tooth is transmission-connected to the active bevel gear on the inner rotating shaft, a group of guide rods are installed on the active pressure frame, each of the guide rods is slidably connected to the fixed frame, a group of first elastic pressure members are installed between the active pressure frame and the elastic pressure frame, the inner pressure ring is rotationally connected to the elastic pressure frame, a connecting frame is hinged on the inner pressure ring and at a position corresponding to each active slider, each of the connecting frame is hinged to an active slider at a corresponding position, a semi-transmission gear is fixedly installed on the bottom end of the upper gear shaft, and a first tooth plate transmission-connected to the semi-transmission gear is fixedly installed on the side of the active pressure frame.

[0025] The beneficial effect of adopting the above further solution is that when the worm motor outputs the speed, the upper gear shaft is driven, and after the upper gear shaft is driven, the transmission connection setting between the semi-transmission gear and the first gear plate and the setting of the first elastic pressure member enable the active pressure frame to reciprocate within the set stroke;

[0026] When the active pressure frame reciprocates within the set stroke, the positions of the elastic pressure frame and the inner pressure ring are reciprocated. After the position of the inner pressure ring is reciprocated, the position of the active slider on the traction wheel is reciprocated and the distance between the active slider and the axis of the traction wheel is reciprocated through the setting of the connecting frame.

[0027] By increasing the distance between the active slider and the traction wheel, the friction between the traction wheel and the wire rope is reciprocatedly increased, thereby effectively improving the anti-skid effect between the traction wheel and the wire rope, thereby improving the stability of the wire rope during operation.

[0028] Furthermore, the reciprocating tensioning component includes two boosting frames and a lower gear shaft rotatably connected to a fixed frame, the lower gear shaft is driven by an upper gear shaft, a reciprocating gear is installed on the lower gear shaft, a group of second elastic pressure members are installed on each of the two tensioning frames, the two groups of the second elastic pressure members are respectively connected to the two boosting frames, second tooth plates are installed on the surfaces of the two boosting frames, the two second tooth plates are both connected to the reciprocating gear in driving connection, and the two second tooth plates are respectively arranged on both sides of the reciprocating gear.

[0029] Furthermore, the inner wall of the fixed frame is rotatably connected to a horizontal axis, and the horizontal axis and the upper gear shaft are both equipped with linked bevel gears, the two linked bevel gears are meshed with each other, a semi-transmission bevel gear is fixedly installed on the horizontal axis, and a second bevel gear meshing with the semi-transmission bevel gear is fixedly installed on the top of the lower gear shaft.

[0030] The beneficial effect of adopting the above further scheme is that after the worm motor outputs the speed, the semi-transmission bevel gear and the second elastic pressure member are set so that the lower gear shaft can reciprocate forward and reverse within the set stroke. After the lower gear shaft reciprocates forward and reverse within the set period, the distance between the two tensioning frames is reciprocated, and then the friction between the tensioning wheel and the wire rope is reciprocated. Through the reciprocating change of the friction between the tensioning wheel and the wire rope, the anti-slip effect between the traction wheel and the wire rope is effectively improved.

[0031] Furthermore, it also includes two guide wheels which are symmetrically arranged and rotatably connected to the fixed frame. Rope grooves are arranged on the guide wheels, the traction wheel and the tensioning wheel corresponding to the position of each steel wire rope, and friction patterns are evenly distributed on the rope grooves.

[0032] Furthermore, it also includes an oil tank arranged on the fixed frame, the interior of the oil tank is filled with asphalt oil, an oil distribution pipe is installed on the fixed frame and at a position corresponding to the top of the traction large wheel, a nozzle is installed on the bottom surface of the oil distribution pipe and at a position corresponding to each wire rope, the oil tank has a built-in pump body, and the oil outlet port of the pump body is connected to the oil distribution pipe through the pump oil pipe.

[0033] The beneficial effect of adopting the above further scheme is that when the worm motor is working, the pump body works periodically for a specified period.

[0049] The principles and features of the present invention are described below in conjunction with the accompanying drawings. The examples given are only used to explain the present invention and are not used to limit the scope of the present invention.

[0050] The present invention provides the following preferred embodiments

[0051] like Figure 1-9 As shown, an anti-skid traction device for steel wire rope on an elevator traction sheave includes a fixing frame 1 and further includes:

[0052] The traction wheel 2 is rotatably connected to the fixed frame 1. The fixed frame 1 is provided with a transmission module. The traction wheel 2 is driven by the transmission module. The transmission module is transmission-connected with an inner bevel gear ring 3. A group of steel wire ropes 4 are provided on the outer side of the traction wheel 2.

[0053] The transmission module includes a worm motor 10 fixed on a fixed frame 1 and an inner rotating shaft 11 arranged at the axis position of the traction large wheel 2, an outer rotating shaft 12 is rotatably sleeved on the inner rotating shaft 11, and the outer rotating shaft 12 is fixedly connected to the inner bevel gear ring 3;

[0054] An active bevel gear is fixedly mounted on the output shaft end of the worm motor 10 , and first bevel gears are mounted on both the outer rotating shaft 12 and the inner bevel gear ring 3 , and two first bevel gears are respectively arranged on both sides of the active bevel gear.

[0055] When the traction operation is in progress, the worm motor 10 outputs the speed at the set power. After the worm motor 10 outputs the speed, the traction wheel 2 and the traction wheel 7 revolve at the set speed on the one hand, and the traction wheel 7 spins at the set speed on the other hand, and the speed and rotation direction of the traction wheel 2 and the traction wheel 7 are the same;

[0056] By setting up the synchronous multi-point multi-power traction structure of the traction wheel 2 and the traction wheel 7 for the wire rope 4, on the one hand, the traction force on the wire rope 4 can be effectively improved, and on the other hand, the friction contact area and friction strength between the wire rope 4 and the traction wheel 2 and the traction wheel 7 can be effectively improved, thereby effectively improving the anti-slip effect of the wire rope 4.

[0057] A group of traction modules distributed in a circular array and installed in the traction wheel 2;

[0058] Each traction module includes an active slider 5 and a driven slider 6 slidably connected to the traction wheel 2, a traction wheel 7 is rotatably connected between the active slider 5 and the driven slider 6, and a guide module linked to the inner bevel gear ring 3 is installed on the active slider 5;

[0059] The guide module includes a hollow shaft 13 rotatably connected to the active slider 5 and a solid shaft 14 rotatably connected to the traction wheel 2;

[0060] The bottom end of the solid shaft 14 is fixedly installed with a linkage bevel gear that is transmission-connected to the inner bevel gear ring 3. The interior of the hollow shaft 13 is fixedly provided with an axis groove with openings at both ends and slidingly connected to the solid shaft 14. Differential bevel gears are installed on the hollow shaft 13 and the traction wheel 7, and the two differential bevel gears are meshed with each other.

[0061] The cross sections of the shaft groove and the solid shaft 14 are both regular polygons, and the axis of the solid shaft 14 is perpendicular to the axis of the traction wheel 2.

[0062] When the wire rope 4 is being pulled, the solid shaft 14 is driven by the inner bevel gear ring 3. After the solid shaft 14 is driven by the inner bevel gear ring 3, the traction wheel 7 can spin at a set speed. Through the shaft groove and the regular polygonal cross section of the solid shaft 14, the hollow shaft 13 can continuously drive the solid shaft 14 during the process of the active slider 5 changing its position.

[0063] The reciprocating expansion and support mechanism is used to elastically change the layout position of the active slider 5 on the traction large wheel 2 and reciprocately change the friction between the traction small wheel 7 and the wire rope 4;

[0064] The reciprocating expansion support mechanism includes an active pressure frame 15, an elastic pressure frame 16, an inner pressure ring 17 and an upper gear shaft 18 rotatably connected to the fixed frame 1, the top of the upper gear shaft 18 is fixedly installed with an upper bevel gear, and the upper bevel gear is transmission-connected to the active bevel gear on the inner rotating shaft 11, a group of guide rods 19 are installed on the active pressure frame 15, each guide rod 19 is slidingly connected to the fixed frame 1, a group of first elastic pressure members 20 are installed between the active pressure frame 15 and the elastic pressure frame 16, the inner pressure ring 17 is rotationally connected to the elastic pressure frame 16, a connecting frame 21 is hinged on the inner pressure ring 17 and at the position corresponding to each active slider 5, each connecting frame 21 is hinged to an active slider 5 at the corresponding position, a semi-transmission gear 22 is fixedly installed on the bottom end of the upper gear shaft 18, and a first tooth plate 23 transmission-connected to the semi-transmission gear 22 is fixedly installed on the side of the active pressure frame 15.

[0065] When the worm motor 10 outputs the speed, the upper gear shaft 18 is driven. After the upper gear shaft 18 is driven, the driving connection between the semi-transmission gear 22 and the first gear plate 23 and the first elastic pressure member 20 enable the active pressure frame 15 to reciprocate within the set stroke.

[0066] When the active pressure frame 15 reciprocates within the set stroke, the positions of the elastic pressure frame 16 and the inner pressure ring 17 are reciprocated. After the position of the inner pressure ring 17 is reciprocated, the position of the active slider 5 on the traction wheel 2 is reciprocated and the distance between the active slider 5 and the axis of the traction wheel 2 is reciprocated through the setting of the connecting frame 21.

[0067] By increasing the distance between the active slider 5 and the traction wheel 2, the friction between the traction wheel 7 and the wire rope 4 is reciprocatingly increased, thereby effectively improving the anti-skid effect between the traction wheel 7 and the wire rope 4, thereby improving the stability of the wire rope 4 during operation.

[0068] Two symmetrically arranged tensioning frames 8, inner walls of the two tensioning frames 8 are rotatably connected with tensioning wheels 9;

[0069] Two tensioning frames 8 are respectively arranged on both sides of the traction wheel 2;

[0070] The reciprocating tensioning component is used to reciprocately change the distance between the two tensioning frames 8.

[0071] The reciprocating tensioning component includes two boosting frames 24 and a lower gear shaft 25 rotatably connected to the fixed frame 1. The lower gear shaft 25 is driven by the upper gear shaft 18. A reciprocating gear 26 is installed on the lower gear shaft 25. A group of second elastic pressure members 27 are installed on the two tensioning frames 8. The two groups of second elastic pressure members 27 are respectively connected to the two boosting frames 24. Second tooth plates 28 are installed on the surfaces of the two boosting frames 24. The two second tooth plates 28 are both connected to the reciprocating gear 26 in transmission connection. The two second tooth plates 28 are respectively arranged on both sides of the reciprocating gear 26.

[0072] The inner wall of the fixed frame 1 is rotatably connected with a transverse shaft 29, and linkage bevel gears are installed on the transverse shaft 29 and the upper gear shaft 18. The two linkage bevel gears are meshed with each other. A semi-transmission bevel gear 30 is fixedly installed on the transverse shaft 29, and a second bevel gear meshing with the semi-transmission bevel gear 30 is fixedly installed on the top of the lower gear shaft 25.

[0073] After the worm motor 10 outputs the speed, the semi-transmission bevel gear 30 and the second elastic pressure member 27 are set so that the lower gear shaft 25 can reciprocate and reverse within the set stroke. After the lower gear shaft 25 reciprocates and reverses within the set period, the distance between the two tensioning frames 8 is reciprocated, and then the friction force between the tensioning wheel 9 and the wire rope 4 is reciprocated. The reciprocating change of the friction force between the tensioning wheel 9 and the wire rope 4 effectively improves the anti-skid effect between the traction wheel 7 and the wire rope 4.

[0074] It also includes two guide wheels 31 symmetrically arranged and rotatably connected to the fixed frame 1. Rope grooves are arranged on the guide wheels 31, the traction wheel 7 and the tension wheel 9 at positions corresponding to each wire rope 4, and friction patterns are evenly distributed on the rope grooves.

[0075] Two guide wheels 31 are respectively arranged on both sides of the tensioning frame 8;

[0076] It also includes an oil tank 32 arranged on the fixed frame 1, the interior of the oil tank 32 is filled with asphalt oil, an oil distribution pipe 33 is installed on the fixed frame 1 and corresponds to the position directly above the traction large wheel 2, and a nozzle is installed on the bottom surface of the oil distribution pipe 33 and at the position corresponding to each wire rope 4. The oil tank 32 has a built-in pump body, and the oil outlet port of the pump body is connected to the oil distribution pipe 33 through the pump oil pipe.

[0077] When the worm motor 10 is working, the pump body works periodically for a specified period. During the working cycle of the pump body, the oil distribution pipe 33 delivers asphalt oil to the surface of the wire rope 4, thereby increasing the friction between the wire rope 4 and the tensioning wheel 9, the traction wheel 7 and the guide wheel 31 through external force.

[0078] A visual acquisition probe 34 facing the steel wire rope 4 is installed on the oil distribution pipe 33 and at the position corresponding to each steel wire rope 4. An audio acquisition sensor 35 is installed on the oil distribution pipe 33. A single-chip computer 36 is installed at the bottom of the fixed frame 1. The visual acquisition probe 34 and the audio acquisition sensor 35 are both data-connected to the single-chip computer 36.

[0079] When in use, a plurality of visual acquisition probes 34 are provided to achieve visual detection of the wear of the wire rope 4;

[0080] By setting the audio collection sensor 35, the running state and running stability of the wire rope 4 are detected by audio collection and audio detection;
