Because the height of the rope head plate is much smaller than the height of the main unit 110, the rising height of the car 140 in the elevator shaft 100 can be effectively increased; further, the left rope head plate 300 is placed horizontally relative to the left rope head plate 300 is placed vertically. The distance between the left rope head plate 300 and the top of the elevator shaft 100 when the left rope head plate 300 is placed horizontally is greater than the distance between the left rope head plate 300 and the top of the elevator shaft 100 when the left rope head plate 300 is placed vertically. In this way, when installing the support frame 200, people can further shorten the distance between the support frame 200 and the top of the elevator shaft 100, thereby further increasing the rising space of the car 140 in the elevator shaft 100.

[0027] Furthermore, when the host 110 is positioned backward, the car 140 is raised and lowered in the elevator shaft 100 , and the car 140 does not contact the host 110 .

[0028] A machine base 160 for installing the main machine 110 and the right rope head plate 120 is provided on the inner wall of the elevator shaft 100, a first sheave 141 is provided on the car 140, a second sheave 210 is provided on the support frame 200, a third sheave 161 is provided on one side of the machine base 160, and a fourth sheave 131 is provided on the counterweight 130. The wire rope 150 passes through the first sheave 141, the second sheave 210, the third sheave 161, the main machine 110 and the fourth sheave 131 in sequence.

[0029] The left rope end plate 300 includes a rope end rod 310, one end of which is provided with a fixed head 320 for connecting the wire rope 150, and a spring 330 is provided on the rope end rod 310. The other end of the rope end rod 310 is connected to one end of the spring 330, and the other end of the spring 330 is connected to a spring plate 340, and the rope end rod 310 moves through the spring plate 340.

[0030] When the left rope end plate 300 is placed vertically, the rope end rod 310 is set vertically relative to the elevator shaft 100, the spring plate 340 is installed on the top of the support frame 200, the rope end rod 310 passes through the top of the support frame 200, and the fixed head 320 passes through the bottom of the support frame 200. In this way, the left rope end plate 300 can be placed vertically on the support frame 200. When the wire rope 150 applies tension to the rope end rod 310, one end of the spring 330 is connected to the rope end rod 310, and the other end of the spring 330 is connected to the spring plate 340, and the spring plate 340 is connected to the top of the support frame 200. In this way, the spring 330 will be compressed to absorb the tension exerted on the rope end rod 310.

[0031] When the left rope head plate 300 is placed horizontally, a fixing frame 400 is required to be provided on one side of the support frame 200, the fixing frame 400 includes two fixing plates 410 connected to the elevator shaft 100, and the two fixing plates 410 are connected by two connecting plates 420, the cross-section of the fixing plate 410 is L-shaped, the rope head rod 310 is arranged horizontally relative to the elevator shaft 100, the spring plate 340 is connected to one of the fixing plates 410, and the rope head rod 310 and the fixing plate 410 are perpendicular to each other in the horizontal plane, the rope head rod 310 passes through the fixing plate 410, an auxiliary wheel 430 is installed between the two connecting plates 420, the fixing plate 410 without the spring plate 340 is connected to the support frame 200, and the wire rope 15 needs to be installed during installation. 0 passes through the auxiliary wheel 430, the first rope pulley 141, the second rope pulley 210, the third rope pulley 161, the main machine 110 and the fourth rope pulley 131 in sequence, so that the left rope end plate 300 can be placed vertically on one side of the support frame 200; when in use, the auxiliary wheel 430 is away from the left rope end plate 300 side. When the wire rope 150 is pulled by the car 140, because the wire rope 150 passes around the auxiliary wheel 430, the wire rope 150 will apply the tension to the rope end rod 310. Because one end of the spring 330 is connected to the rope end rod 310, the other end of the spring 330 is connected to the spring plate 340, and the spring plate 340 is connected to the fixed plate 410, the spring 330 will be compressed to absorb the tension on the rope end rod 310.

[0032] Example 2

[0033] like Figure 4 — Figure 5 As shown, this embodiment is an improved structure when the left rope head plate 300 in the first embodiment is placed horizontally.

[0034] A safety component 500 is provided between the two connecting plates 420, and the safety component 500 is located between the left rope head plate 300 and the auxiliary wheel 430. The wire rope 150 passes through the safety component 500. A ball head 151 is provided on the wire rope 150, and the ball head 151 is located between the left rope head plate 300 and the safety component. When the wire rope 150 is subjected to a large tension and the wire rope 150 breaks directly from the fixed head 320, the ball head 151 will separate from the fixed head 320. At this time, the ball head 151 will enter the safety component 500 with the tension of the wire rope 150 and be stuck by the safety component 500. In this way, the car 140 can be effectively prevented from continuing to fall, thereby improving the safety of passengers riding in the car 140.

[0035] The safety assembly 500 includes a safety platform 510 connected to the connecting plate 420. The safety platform 510 is provided with a first channel 520 for the wire rope 150 to pass through. The safety platform 510 is provided with a pair of clamping members 530 for limiting the movement of the ball head 151. The two clamping members 530 are respectively located on both sides of the first channel 520. The clamping members 530 include a clamping block 531 movably mounted in the safety platform. The clamping block 531 is provided with a cylinder rod 533. The cylinder 532 is provided with a cylinder rod 533 and a clamping block 531. A limiting groove 534 for accommodating the clamping block 531 is provided in the safety platform 510. A hemispherical clamping groove 531a is provided on the end surface of each clamping block 531. A cover plate 540 is detachably connected to the safety platform 510. A second channel 541 corresponding to the first channel 520 is provided in the cover plate 540. The first channel 520 and the second channel 541 are both provided with a buffer block 550. Before use, people need to adjust the distance between the two clamping blocks 531 respectively through the two cylinders 532 so that the distance between the two clamping blocks 531 is less than the width of the channel and the distance between the two clamping blocks 531 is less than the diameter of the ball head 151. When the wire rope 150 breaks and the ball head 151 enters the safety component 500, the ball head 151 will move toward the auxiliary wheel 430 along the trajectory of the first channel 520 and the second channel 541. During this process, the buffer block 550 will buffer the ball head 151 to reduce the travel speed of the ball head 151. After that, the ball head 151 will hit the clamping member 530 and be embedded in the slot 531a of the clamping block 531. At this time, the clamping block 531 will be supported by the cylinder rod 533 and the inner wall of the limiting groove 534, so that the clamping block 531 will not move relative to the limiting groove 534, that is, the clamping block 531 can stably support the ball head 151 of the column.
