However, it will be appreciated by those of ordinary skill in the art that numerous technical details are set forth in various embodiments of the present application in order to provide a better understanding of the present application. However, the technical means claimed in the present application can be realized by various changes and modifications of the following embodiments.

Referring to fig. 1 to 5, some embodiments of the present application provide an elevator trailing cable testing device, including: a first pulley 110, a second pulley 120, a first timing belt 130, a first fixing member 140, a second fixing member 150, a third fixing member 160, and a fourth fixing member 170; the first belt pulley 110 and the second belt pulley 120 are in transmission connection with a first synchronous belt 130; the first synchronous belt 130 is divided into a first section 131, a second section 132, a third section 133 and a fourth section 134 which are sequentially connected end to end, the first section 131 is fixed with the first fixing piece 140, the second section 132 is attached to the outer wheel surface of the first belt wheel 110, the third section 133 is fixed with the second fixing piece 150, and the fourth section 134 is attached to the outer wheel surface of the second belt wheel 120; the first fixing member 140, the second fixing member 150, the third fixing member 160 and the fourth fixing member 170 are used for fixing the end of the elevator traveling cable, the third fixing member 160 is located on the side of the first section 131 far away from the third section 133, and the fourth fixing member 170 is located on the side of the third section 133 far away from the first section 131.

After one end of a part of the cable is fixed to the first fixing member 140 and the other end of the part of the cable is fixed to the third fixing member 160, and one end of the other part of the cable is fixed to the second fixing member 150 and the other end of the other part of the cable is fixed to the fourth fixing member 170, the end of the cable fixed to the first fixing member 140 and the end of the cable fixed to the second fixing member 150 can reciprocate by the forward and reverse rotation of the first pulley 110 and the second pulley 120, and the situation of the cable when the cable is used can be simulated.

The forward and reverse rotation of the first pulley 110 and the second pulley 120 is that the first pulley 110 and the second pulley 120 rotate forward and then rotate reversely to circulate the motion. When the first pulley 110 and the second pulley 120 rotate in the forward and reverse directions, the first pulley 110 can be driven by a driving actuator (such as a motor) to rotate in the forward and reverse directions, so that the first synchronous belt 130 drives the second pulley 120 to rotate in the forward and reverse directions.

In addition, when the first pulley 110 and the second pulley 120 rotate in the forward and reverse directions, the first pulley 110 and the second pulley 120 simultaneously drive the end of the cable fixed on the first fixing member 140 and the end of the cable fixed on the second fixing member 150 to move back and forth, and the first section 131 is fixed with the first fixing member 140, the second section 132 is attached to the outer wheel surface of the first pulley 110, the third section 133 is fixed with the second fixing member 150, and the fourth section 134 is attached to the outer wheel surface of the second pulley 120, so the second section 132 and the fourth section 134 are distributed on two sides of the first pulley 110 and the second pulley 120, and the driving actuator is uniformly stressed when the first pulley 110 is driven to move.

Specifically, in one embodiment, when the first pulley 110 rotates forward, the second segment 132 moves in a direction close to the first pulley 110 and away from the second pulley 120, and at the same time, the fourth segment 134 moves in a direction close to the second pulley 120 and away from the first pulley 110; when the first pulley 110 is rotated forward such that the second segment 132 is adjacent to the position of the first pulley 110 or the fourth segment 134 is adjacent to the position of the second pulley 120, the first pulley 110 starts to rotate in reverse; when the first pulley 110 is reversed, the second segment 132 moves in a direction away from the first pulley 110 and closer to the second pulley 120, and at this time, the fourth segment 134 moves in a direction away from the second pulley 120 and closer to the first pulley 110; when the first pulley 110 rotates in reverse such that the second segment 132 is adjacent to the second pulley 120 or the fourth segment 134 is adjacent to the first pulley 110, the first pulley 110 starts to rotate in forward again. Therefore, the condition of the elevator traveling cable in use can be well simulated.

With continued reference to fig. 1-5, in some embodiments, the elevator trailing cable testing apparatus further comprises: a third pulley 180, a fourth pulley 190, a second timing belt 200, a first connecting shaft 210, and a second connecting shaft 220; the first pulley 110, the second pulley 120, the third pulley 180, and the fourth pulley 190 are all the same size; the first pulley 110 and the third pulley 180 are both coaxially disposed and fixed with the first connecting shaft 210; the second pulley 120 and the fourth pulley 190 are coaxially disposed and fixed with the second connecting shaft 220; the third belt wheel 180 and the fourth belt wheel 190 are in transmission connection with a second synchronous belt 200; the first fixing member 140 is a first fixing rod, an extending direction of the first fixing rod (i.e., the first fixing member 140) is axially parallel to the first connecting shaft 210, one end of the first fixing rod is fixed on the first section 131, and the other end of the first fixing rod is fixed on the second synchronous belt 200, the first fixing rod is sequentially provided with a plurality of first fixing positions 141 in the extending direction, and each first fixing position 141 is used for fixing one end of one elevator traveling cable; the second fixing member 150 is a second fixing rod, an extending direction of the second fixing rod (i.e., the second fixing member 150) is axially parallel to the first connecting shaft 210, one end of the second fixing rod is fixed on the third section 133, and the other end of the second fixing rod is fixed on the second synchronous belt 200, the second fixing rod is sequentially provided with a plurality of second fixing positions 151 in the extending direction, and each second fixing position 151 is used for fixing one end of one elevator traveling cable.

Thus, the two timing belts (i.e., the first timing belt 130 and the second timing belt 200) are used to drive the first fixing element 140 and the second fixing element 150 to reciprocate, so as to improve the stability of the first fixing element 140 and the second fixing element 150 during movement.

Referring to fig. 1 to 5, in some embodiments, the third fixing member 160 includes a plurality of third fixing locations 161 having the same number as the first fixing locations 141, and the plurality of third fixing locations 161 correspond to the plurality of first fixing locations 141 one-to-one, where a position of each third fixing location 161 is adjustable, so that a distance between the third fixing location 161 and the corresponding first fixing location 141 in a preset direction is adjustable, and the preset direction is perpendicular to a plane where the first connecting shaft 210 and the second connecting shaft 220 are located. Wherein, the first fixing position 141 and the third fixing position 161 corresponding to each other are respectively used for fixing two ends of one elevator traveling cable.

Because the bending radii of the elevator trailing cables of different sizes and/or configurations are different, different bending radii of the elevator trailing cables can be accommodated by adjusting the positions of the third fixing locations 161 when the bending radii of the elevator trailing cables having ends suspended on the first fixing member 140 are different.

In some embodiments, the elevator trailing cable testing apparatus further comprises: the first guide rail (not shown in the figure) and a plurality of first sliding blocks (not shown in the figure) with the same number as the third fixing positions 161 are arranged on the first guide rail, the extending direction of the first guide rail is axially vertical to the first connecting shaft 210, the plurality of first sliding blocks are all slidably arranged on the first guide rail, the plurality of first sliding blocks are in one-to-one correspondence with the plurality of third fixing positions 161, and the first sliding blocks are fixed with the corresponding third fixing positions 161.

In this way, when the position of the third fixing station 161 needs to be adjusted, so as to adjust the distance between the third fixing station 161 and the corresponding first fixing station 141 in the preset direction, the first slider corresponding to the third fixing station 161 can slide on the first guide rail.

Referring to fig. 1-5, in further embodiments, an elevator trailing cable testing apparatus further comprises: the extending directions of the second guide rails 230 are all vertical to the axial direction of the first connecting shaft 210, the second slide blocks 240 are in one-to-one correspondence with the second guide rails 230, the second slide blocks 240 are slidably arranged on the second guide rails 230 corresponding to the second guide rails, the second slide blocks 240 are in one-to-one correspondence with the third fixing positions 161, and the second slide blocks 240 are fixed with the third fixing positions 161 corresponding to the second slide blocks 240.

Thus, when the position of the third fixing portion 161 needs to be adjusted, so as to adjust the distance between the third fixing portion 161 and the corresponding first fixing portion 141 in the preset direction, the second slider 240 corresponding to the third fixing portion 161 can slide on the second guide rail 230 corresponding to the second slider 240.

Referring to fig. 1 to 5, in some embodiments, the fourth fixing element 170 includes a plurality of fourth fixing locations 171 having the same number as the second fixing locations 151, and the plurality of fourth fixing locations 171 correspond to the plurality of second fixing locations 151 in a one-to-one manner, where a position of each fourth fixing location 171 is adjustable, so that an interval between the fourth fixing location 171 and the corresponding second fixing location 151 in a preset direction is adjustable. Wherein, the second fixing position 151 and the fourth fixing position 171 corresponding to each other are respectively used for fixing two ends of an elevator traveling cable.

Since the bending radii of the elevator trailing cables of different sizes and/or configurations are different, when the bending radii of the elevator trailing cables having ends suspended on the second fixing member 150 are different, the positions of the fourth fixing locations 171 can be adjusted to accommodate the different bending radii of the elevator trailing cables.

It should be noted that the specific embodiment for adjusting the position of the fourth fixing portion 171 in the present application may be the same as the embodiment for adjusting the position of the third fixing portion 161 in the foregoing embodiment, and is not described herein again.
