Description
Technical Field
The invention belongs to the technical field of electric clothes hangers, and particularly relates to an auxiliary line control mechanism of an electric lifting clothes hanger.
Background
The electric lifting type clothes hanger is intelligent furniture which can be equipped for many families, so that the inconvenience caused by manual lifting is avoided, and more additional functions are given to the clothes hanger.
In the electric lifting clothes hanger, the lifting of the clothes drying rod is realized by a lifting control device. The Chinese patent application with the publication number of CN108134484A discloses a clothes hanger driving motor, which comprises a shell and a driving mechanism, wherein the driving mechanism is arranged in the shell; the driving mechanism comprises a direct current motor, a rope winder and a circuit control module, wherein the rope winder is connected with the direct current motor through a worm gear and a worm; the rope winder is connected with an upper limiting mechanism, a lower limiting mechanism and a stop mechanism, an upper travel switch and a lower travel switch are arranged in the upper limiting mechanism and the lower limiting mechanism, a stop travel switch is arranged in the stop mechanism, and the circuit control module is electrically connected with the upper travel switch, the lower travel switch and the stop travel switch, receives on-off signals of the upper travel switch, the lower travel switch and the stop travel switch, and controls the on-off of the direct current motor.
The upper and lower limiting mechanisms also comprise a transmission gear which is connected with the worm gear and synchronously rotates along with the worm gear, and the transmission gear is meshed with the reduction gear set; the upper limiting ring and the lower limiting ring are coaxially arranged, and the lower limiting ring is provided with meshing teeth meshed with the reduction gear set; a lower limiting sheet is arranged between the upper limiting ring and the lower limiting ring, and the side wall of the upper limiting ring is provided with an upper limiting sheet; after the upper limit piece and the lower limit piece rotate synchronously, the contact piece of the upper travel switch and the contact piece of the lower travel switch can be respectively touched.
The upper and lower limiting mechanisms can only be used for controlling starting and stopping of the direct current motor, however, when the lifting pulling wire reaches the upper and lower limit positions, the lifting pulling wire loaded with the clothes hanger can always pull the rope winder, so that a large load is caused to the rope winder and the motor; and when the lifting pulling line is suddenly loosened (the lower end is blocked or the upper end is separated from the rope winder), the upper limiting mechanism and the lower limiting mechanism cannot send signals to the electric control mechanism in time to stop the motor, and the lifting pulling line is difficult to grasp in time, so that the clothes hanger is in danger of suddenly falling.
Disclosure of Invention
The invention aims to provide an auxiliary line control mechanism of an electric lifting clothes hanger, which can clamp and position a lifting pulling line after the lifting pulling line reaches a limit position or perform safety when the lifting pulling line suddenly extends out excessively.
In order to achieve the purpose, the technical scheme of the invention is as follows:
an auxiliary line control mechanism of an electric lifting clothes hanger comprises a swinging piece, one end of the swinging piece is hinged at a hinged point at one side of a lifting pulling line, a lateral touch switch is arranged on one side of the swinging piece, an elastic structure which enables the swinging piece to swing towards the lateral touch switch is connected to the swinging piece, the lifting traction wire penetrates through the swinging piece and exerts acting force for counteracting the swinging trend to the swinging piece when the lifting traction wire is in a normal state of tension, and when the lifting pulling wire is lower than the normal tightening state, the swinging piece swings towards the lateral touch switch and contacts with the lateral touch switch so as to generate a control signal, the lateral touch control switch is electrically connected with an electric control mechanism for controlling and driving the lifting traction line to move, and when the electric control mechanism receives a control signal generated by the lateral touch switch, the electric control mechanism controls the driving motor to stop working.
In the auxiliary line control mechanism, the swinging piece and the lateral touch switch are oppositely arranged, and the swinging piece has a tendency of swinging towards the lateral touch switch under the action of the elastic structure; however, since the lifting pulling wire is arranged on the swinging member in a penetrating manner, when the lifting pulling wire works normally and is in a tensed state, the lifting pulling wire can generate lateral pressure on the swinging member, the lateral pressure can counteract the swinging trend of the swinging member to the lateral touch switch, and the lateral touch switch is not triggered at the moment. When the lifting pulling line reaches the limit position and stops lifting or the line end is loosened (namely, the side pressure is lower than the normal state in a tightened state), the side pressure exerted on the swinging piece by the lifting pulling line disappears, the swinging piece swings towards the side touch switch under the action of the elastic structure, and the side touch switch is triggered; after the electric control mechanism receives a ground control signal sent by the lateral touch switch, the electric control mechanism immediately commands the driving motor to stop working and stops retracting the lifting pull wire; meanwhile, the swinging of the swinging piece can also clamp the lifting pulling line to prevent the lifting pulling line from lifting.
The auxiliary wire control mechanism can not only assist the upper limit switch and the lower limit switch to stop the driving motor in time when the lifting traction wire reaches the upper limit position and the lower limit position, but also clamp the lifting traction wire, and reduce the load pressure of the reel and the driving motor to a certain extent; and when the lifting pulling line is accidentally loosened, the driving motor can be stopped in time and the lifting pulling line can be clamped and positioned, so that the clothes hanger is prevented from falling suddenly.
In the auxiliary line control mechanism of the electric lifting clothes hanger, the swinging piece is arranged at a pulling line inlet and outlet of a main machine of the electric lifting clothes hanger, the swinging piece is hinged to the main machine, a hinged point is located at one side of the pulling line inlet and outlet, and the lateral touch switch is fixed on the main machine and located at the other side of the pulling line inlet and outlet.
In the auxiliary line control mechanism of the electric lifting clothes hanger, the elastic structure comprises a torsion spring arranged at a hinge point; or the elastic structure comprises a tension spring, one end of the tension spring is connected to one end of the swinging piece, and the other end of the tension spring is connected to the host machine.
In the auxiliary line control mechanism of the electric lifting clothes hanger, the swinging piece is provided with a line passing groove, and the lifting pulling line penetrates through the line passing groove.
In the auxiliary line control mechanism of the electric lifting clothes hanger, a rolling body is arranged on one side of the line passing groove, when the lifting pulling wire is in a normal state in a tight state, the lifting pulling wire passes through the line passing groove in a suspended mode and is in rolling contact with the rolling body, and when the swinging piece swings to be in contact with the lateral touch switch, the lifting pulling wire is in contact with the wall of the line passing groove. When the lifting traction line normally works in a normal state and is in a normally tightened state, the lifting traction line only contacts with the rolling body in a rolling manner, so that the lifting traction line can apply an acting force for offsetting the swinging trend of the swinging piece to the swinging piece, the lifting traction line can be protected, and the phenomenon that the service life of the lifting traction line is shortened due to excessive friction is avoided. When the lifting pulling line is lower than the normal state in a tightening state, the swinging of the swinging piece can lead the lifting pulling line to be contacted with the groove wall of the wire passing groove, thereby realizing the clamping and positioning of the lifting pulling line.
In the auxiliary line control mechanism of the electric lifting clothes hanger, the line passing groove is in a strip shape, and the extending direction of the line passing groove is consistent with the width direction of the pull line pulling inlet and outlet. Therefore, on one hand, enough space is provided for normal lifting of the lifting pulling and pulling line, on the other hand, the swinging distance of the swinging piece required for clamping the lifting pulling and pulling line is shortened, so that once the lifting pulling and pulling line is abnormal in work, the swinging piece can quickly respond to the lifting pulling and pulling line, and the lifting pulling and pulling line is clamped.
In the auxiliary line control mechanism of the electric lifting clothes hanger, the rolling bodies are cylindrical and are arranged in parallel with the line passing grooves. Thus, enough space can be further provided for normal lifting of the lifting pulling line.
When the lifting pulling wire is clamped and positioned, the lifting pulling wire is in a folded angle state at the swinging part and is respectively attached to the surface of the rolling body and the wall of the wire passing groove. However, the groove wall of the wire passing groove has edges and corners, so that the lifting pulling wire is worn. Therefore, in the auxiliary line control mechanism of the electric lifting clothes hanger, the middle part of one side of the line passing groove close to the rolling body is provided with a concave area, and the lifting pulling line is positioned in the concave area when the swinging piece swings to be in contact with the lateral touch switch. The sunken area enables the lifting pulling line not to contact with the edges and corners between the walls when the lifting pulling line contacts with the wire passing groove, and the lifting pulling line is prevented from being abraded.
The auxiliary line control mechanism of the electric lifting clothes hanger is characterized in that the swinging piece is L-shaped, one end of the swinging piece is hinged with the main machine through a hinge shaft, the other end of the swinging piece faces the lateral touch switch, and the touch point of the lateral touch switch is located on the arc track of the end.
In the auxiliary line control mechanism of the electric lifting clothes hanger, the lateral touch switch is a microswitch. The micro switch has high sensitivity and can quickly respond and generate a control signal.
Compared with the prior art, the invention has the beneficial effects that:
(1) in the auxiliary line control mechanism, the swinging piece and the lateral touch switch are oppositely arranged, and the swinging piece has a tendency of swinging towards the lateral touch switch under the action of the elastic structure; however, since the lifting pulling wire is arranged on the swinging member in a penetrating manner, when the lifting pulling wire works normally and is in a tensed state, the lifting pulling wire can generate lateral pressure on the swinging member, the lateral pressure can counteract the swinging trend of the swinging member to the lateral touch switch, and the lateral touch switch is not triggered at the moment. When the lifting pulling line reaches the limit position and stops lifting or the line end is loosened (namely, the side pressure is lower than the normal state in a tightened state), the side pressure exerted on the swinging piece by the lifting pulling line disappears, the swinging piece swings towards the side touch switch under the action of the elastic structure, and the side touch switch is triggered; after the electric control mechanism receives a ground control signal sent by the lateral touch switch, the electric control mechanism immediately commands the driving motor to stop working and stops retracting the lifting pull wire; meanwhile, the swinging of the swinging piece can also clamp the lifting pulling line to prevent the lifting pulling line from lifting.
(2) The auxiliary wire control mechanism can not only assist the upper limit switch and the lower limit switch to stop the driving motor in time when the lifting traction wire reaches the upper limit position and the lower limit position, but also clamp the lifting traction wire, and reduce the load pressure of the reel and the driving motor to a certain extent; and when the lifting pulling line is accidentally loosened, the driving motor can be stopped in time and the lifting pulling line can be clamped and positioned, so that the clothes hanger is prevented from falling suddenly.

In the installation mode that the box cover 12 of the main machine 1 is arranged at the lower part and the box body 11 is arranged at the upper part, the solid lubricating oil can be put into the oil storage tank 14.
As shown in fig. 4 and 5 and seen in fig. 3, the main body 1 is provided with a signal acquisition unit 6 connected with the electric control mechanism, and the signal acquisition unit 6 is used for acquiring the rotation number signal of the worm 21 and the rotation number signal of the winding wheel 3.
In this embodiment, the signal collecting unit 6 includes a first magnetic body (not shown in the figure) fixed on the worm 21 and a second magnetic body (not shown in the figure) fixed on any of the winding wheels 3, the worm 21 is formed with a first through hole 21a for mounting the first magnetic body, the winding wheel 3 is formed with a second through hole 32 for mounting the second magnetic body; the first magnetic body is arranged corresponding to the first hall sensing element 61 fixedly arranged on the host 1, the second magnetic body is arranged corresponding to the second hall sensing element 62 fixedly arranged on the host 1, and the first hall sensing element 61 and the second hall sensing element 62 are respectively connected with the electric control mechanism.
When at least one of the number of turns of the worm 21 and the number of turns of the winding wheel 3 reaches a preset value, the signal acquisition unit 6 sends a control signal to the electric control mechanism, and the electric control mechanism commands the driving motor 2 to stop working. The power shaft of the driving motor 2 and the winding wheel 3 are in linkage relation, the power shaft and the winding wheel rotate synchronously and are directly associated with the driving motor 2, so that signals acquired by the signal acquisition unit 6 can be fed back to the electric control mechanism in real time, and the electric control mechanism can also control the driving motor 2 timely and quickly.
Besides the signal acquisition unit 6 is adopted to control the driving motor 2, the braking mechanism 4 is also arranged as an auxiliary in the embodiment, so as to improve the control precision of the electric control mechanism to the driving motor 2.
As shown in fig. 2 and 3, the braking mechanism 4 includes an upper travel touch switch 41 and a lower travel touch switch 42 connected to the electric control mechanism, the upper travel touch switch 41 and the lower travel touch switch 42 are fixedly mounted on the box body 11 and are both located at the periphery of the trigger turntable 44, and an upper limit stopper 44a and a lower limit stopper 44b are disposed at the outer edge of the trigger turntable 44; the winding wheel 3 is connected with the trigger turntable 44 through the gear speed reducing structure 43 and can drive the trigger turntable 44 to rotate, and the upper limit stop 44a and the lower limit stop 44b can be respectively contacted with the upper travel touch switch 41 and the lower travel touch switch 42 after the trigger turntable 44 rotates for a set angle so as to respectively generate an upper travel signal and a lower travel signal.
As shown in fig. 7 and seen in conjunction with fig. 3, in the present embodiment, the gear reduction structure 43 includes a first small gear 43a rotating coaxially with the winding wheel 3, a ring gear 43b provided on the trigger rotary table 44, and a double gear 43c rotatably connected to the main body 1, the double gear 43c includes a large gear 43ca and a second small gear 43cb coaxially provided, the large gear 43ca is in meshing transmission with the first small gear 43a, and the second small gear 43cb is in meshing transmission with the ring gear 43 b.
The first small gear 43a rotating coaxially with the winding wheel 3 can realize the first reduction transmission, the large gear 43ca and the first small gear 43a meshed with each other can realize the second reduction transmission, and the second small gear 43cb and the gear ring 43b meshed with each other can realize the third reduction transmission, so that the rotation number of the trigger rotary plate 44 can be effectively controlled within one circle.
When the number of turns of the winding wheel 3 reaches a preset value (the trigger turntable 44 rotates by a set angle), an upper limit stopper 44a on the outer edge of the trigger turntable 44 just contacts with the upper stroke touch switch 41 to generate an upper stroke signal; or the lower limit stop 44b just contacts with the lower stroke touch switch 42 to generate a lower stroke signal; after the electric control mechanism receives the up stroke signal or the down stroke signal, the electric control mechanism commands the driving motor 2 to stop working.
The braking of the driving motor 2 caused by the signal acquisition unit 6 and the braking mechanism 4 is synchronous, and the braking are complementary, so that the functional stability of the electric control mechanism and the driving motor 2 can be improved.
As shown in fig. 2 and 3, a stroke setting structure 7 capable of adjusting the position of the upper limit stopper 44a on the circumference of the trigger dial 44 to change the upper stroke is further provided between the trigger dial 44 and the upper limit stopper 44 a. The position of the upper limit stopper 44a on the circumference of the trigger turntable 44 can be adjusted by using the stroke setting structure 7, so that the contact time between the upper limit stopper 44a and the upper stroke touch switch 41 is adjusted, and the stroke of the lifting pulling wire 100 can be adjusted in a user-defined manner.
In this embodiment, the stroke setting structure 7 includes an adjusting block 71 having an upper limit stop 44a, the adjusting block 71 has at least one first positioning hole 71a, the outer edge of the trigger turntable 44 has a plurality of second positioning holes 72 distributed in the circumferential direction, and the first positioning hole 71a and the second positioning holes 72 are fixedly connected by a fastener; and the lower limit stopper 44b is integrally connected to the trigger dial 44.
The first positioning hole 71a may be circular or circular as shown in fig. 2, and the circular first positioning hole 71a has a wider adjustable range and can adjust the position of the adjusting block 71 more precisely than the circular first positioning hole 71 a.
Of course, the lower limit stopper 44b may be configured to move along the outer edge of the trigger disk 44, and the upper limit stopper 44a may be configured to be integrated with the trigger disk 44; alternatively, the upper limit stopper 44a and the lower limit stopper 44b may be provided so as to be movable along the outer periphery of the trigger dial 44.
As shown in fig. 2 and 3, the surface of the trigger dial 44 is further provided with a stroke indication mark 73, and the adjusting block 71 is provided with a pointing part 71b, so that when the adjusting block 71 changes position, the pointing part 71b points to different positions of the stroke indication mark 73. Therefore, the user can conveniently and quickly adjust the position of the adjusting block 71 according to the specific application scene.
The signal acquisition unit 6 and the brake mechanism 4 can only control the stroke end point of the lifting traction line 100, but when the lifting traction line 100 reaches the upper and lower extreme positions, the lifting traction line 100 loaded with the clothes hanger can always pull the winding wheel 3, so that a large load is caused to the winding wheel 3 and the drive motor 2; and when the lifting pulling line 100 is suddenly loosened (the lower end is blocked or the upper end is separated from the winding wheel 3), the signal acquisition unit 6 and the brake mechanism 4 cannot send signals to the electric control mechanism in time to stop the driving motor 2, and the lifting pulling line 100 is difficult to grasp in time, so that the clothes hanger is in danger of suddenly falling.
Therefore, as shown in fig. 2 and 3 and fig. 4 and 5, the box 11 is provided with two guy wire entrances and exits 15 corresponding to the two winding wheels 3, respectively, and each guy wire entrance and exit 15 is provided with the auxiliary wire control mechanism 5 of the present embodiment.
In this embodiment, the auxiliary wire control mechanism 5 includes a swinging member 51, the swinging member 51 is L-shaped, and one end of the swinging member 51 is hinged to the box body 11 through a hinge shaft 52 to form a hinge point 50 located at one side of the pull-cord passageway 15; a lateral touch switch 53 is fixedly mounted on the box body 11 and located on the other side of the pull lead access opening 15, and a touch point 53a of the lateral touch switch 53 is located on an arc track of the end of the swinging member 51.
The swinging member 51 is provided with a wire passing groove 51a, and the lifting pulling wire 100 is inserted into the wire passing groove 51 a. As shown in fig. 2 and 3, the wire passage groove 51a is elongated and extends in the direction corresponding to the width direction of the pull lead doorway 15. The length of the wire passing groove 51a is equivalent to the width of the pulling line access 15, so that enough space can be provided for the normal retraction of the lifting pulling line 100; the width of the wire passing groove 51a is narrow, and when the swinging piece 51 swings, the lifting traction line 100 can be driven to deviate from the original running track only by swinging a small distance, so that the lifting traction line 100 is clamped and positioned.
As shown in fig. 2, the swinging member 51 is provided with an elastic structure 54 that makes the swinging member 51 swing toward the lateral touch switch 53, however, since the lifting and lowering pulling wire 100 is inserted into the swinging member 51, when the lifting and lowering pulling wire 100 is working normally and in a normal state of tension, the lifting and lowering pulling wire 100 generates a lateral pressure on the swinging member 51, the lateral pressure can counteract the swinging tendency of the swinging member 51 toward the lateral touch switch 53, and the lateral touch switch 53 is not triggered. When the lifting pulling line 100 reaches the limit position to stop lifting or the line end is loosened (i.e. lower than the normal state of tension), the lateral pressure exerted on the swinging member 51 by the lifting pulling line 100 disappears, the swinging member 51 swings towards the lateral touch switch 53 under the action of the elastic structure 54, and the lateral touch switch 53 is triggered; after receiving a control signal sent by the touch switch, the electric control mechanism immediately commands the driving motor 2 to stop working and stops retracting the lifting pull wire 100; meanwhile, the swinging of the swinging piece 51 can also clamp the lifting and pulling wire 100, so as to prevent the lifting and pulling wire 100 from lifting.
The lateral touch switch 53 selected in this embodiment is a microswitch, which has high sensitivity and can respond quickly to generate a control signal.
The elastic structure 54 used in this embodiment includes a tension spring 54a, one end of the tension spring 54a is connected to one end of the swing member 51, and the other end is connected to the box body 11.
As shown in fig. 5 and as seen in fig. 2 and 3, a cylindrical rolling body 55 is rotatably mounted on the swinging member 51 on the side facing the pull lead entrance 15, and the rolling body 55 is disposed in parallel with the wire passage groove 51 a. When the lifting traction line 100 is in a normal tightening state, the lifting traction line 100 is suspended to pass through the thread groove 51a and is in rolling contact with the rolling body 55, so that the lifting traction line 100 can apply an acting force for counteracting the swinging trend of the swinging piece 51 to the swinging piece 51, the lifting traction line 100 can be protected, and the service life is prevented from being shortened due to excessive friction of the lifting traction line 100; when the swinging member 51 swings to contact with the lateral touch switch 53, the lifting pulling wire 100 contacts with the wall of the wire passing groove 51a, so as to clamp and position the lifting pulling wire 100.
When the lifting and pulling wire 100 is clamped and positioned, the lifting and pulling wire 100 is in a folded angle state at the swinging piece 51, and the lifting and pulling wire 100 is respectively attached to the surface of the rolling body 55 and the groove wall of the wire passing groove 51 a. However, the lifting and pulling wire 100 is worn due to the angular edges between the groove walls of the wire passing groove 51 a. Therefore, as shown in fig. 2 and fig. 3, in the present embodiment, a recessed area 51b is provided in a middle portion of the wire passing groove 51a near the rolling body 55, and when the swinging member 51 swings to contact with the lateral touch switch 53, the lifting pulling wire 100 is located in the recessed area 51 b. The recessed area 51b prevents the lifting pulling wire 100 from contacting the corner between the walls when the lifting pulling wire 100 contacts the wire passing groove 51a, thereby preventing the lifting pulling wire 100 from being worn.
When the lifting traction line 100 needs to be put down, the driving motor 2 is started, the driving motor 2 drives the winding wheel 3 to rotate through the worm 21, the lifting traction line 100 is released, and the lifting traction line 100 goes down after passing through the traction line access 15 and the line passing groove 51 a; in the process, the signal acquisition unit 6 acquires a rotation number signal of the worm 21 and a rotation number signal of the winding wheel 3, and the trigger turntable 44 is driven by the winding wheel 3 to slowly rotate; when the number of turns of the worm 21 and the number of turns of the winding wheel 3 detected by the signal acquisition unit 6 are equal to the preset values, the lower limit stop 44b also contacts the lower travel touch switch 42, and the electric control mechanism receives control signals sent by the signal acquisition unit 6 and the lower travel touch switch 42 and orders the driving motor 2 to stop working.
When the lifting traction line 100 needs to be retracted, the driving motor 2 is started again, the worm 21 drives the winding wheel 3 to rotate reversely, the lifting traction line 100 is wound up, and the lifting traction line 100 goes upwards after penetrating through the traction line inlet/outlet 15 and the line passing groove 51 a; in the process, the signal acquisition unit 6 acquires a rotation number signal of the worm 21 and a rotation number signal of the winding wheel 3, and the trigger turntable 44 is driven by the winding wheel 3 to slowly rotate; when the number of turns of the worm 21 and the number of turns of the winding wheel 3 detected by the signal acquisition unit 6 are equal to the preset values, the upper limit stop 44a also contacts the upper travel touch switch 41, and the electric control mechanism receives control signals sent by the signal acquisition unit 6 and the upper travel touch switch 41 and orders the driving motor 2 to stop working.
The working principle of the auxiliary line control mechanism of the electric lifting clothes hanger in the embodiment is as follows:
in the whole lowering or retracting process of the lifting traction line 100, the lifting traction line 100 is in a normal state and is in a tight state, and the acting force exerted on the swinging piece 51 by the lifting traction line 100 enables the swinging piece 51 not to swing towards the lateral touch switch 53; when the lifting pulling wire 100 reaches the lower limit position or the upper limit position, the acting force exerted on the swinging piece 51 by the lifting pulling wire 100 disappears, the swinging piece 51 swings towards the lateral touch switch 53 under the driving of the tension spring 54a, when the swinging piece 51 contacts the touch point 53a of the lateral touch switch 53, the lateral touch switch 53 sends a control signal to the electric control mechanism, and after the electric control mechanism receives the control signal sent by the touch switch, the electric control mechanism immediately commands the driving motor 2 to stop working, and stops putting down or taking up the lifting pulling wire 100; meanwhile, after the swinging piece 51 swings in place, the lifting traction line 100 is also clamped, so that the lifting traction line 100 is prevented from lifting.
In the process of lowering the lifting and pulling line 100, if the lower part of the clothes hanger is blocked, and in the process of lowering or retracting the lifting and pulling line 100, if the end part of the lifting and pulling line 100 is loosened from the winding wheel 33 and rapidly lowered, the lifting and pulling line 100 can not keep in a tight state; at this time, the acting force exerted on the swinging member 51 by the lifting pulling wire 100 also disappears, the swinging member 51 swings towards the lateral touch switch 53 under the driving of the tension spring 54a, when the swinging member 51 contacts the touch point 53a of the lateral touch switch 53, the lateral touch switch 53 sends a control signal to the electric control mechanism, and the electric control mechanism immediately orders the driving motor 2 to stop working after receiving the control signal sent by the touch switch, and stops lowering or retracting the lifting pulling wire 100; meanwhile, after the swinging piece 51 swings in place, the lifting traction line 100 is also clamped, so that the lifting traction line 100 is prevented from continuously lifting.
