[0039] The present invention is further described in detail below through specific embodiments in conjunction with the accompanying drawings.
[0040] See also Figure 1 , Figure 2 and Figure 3 As shown, this embodiment provides a wire rope anti-slip device for a traction-type hoistway construction elevator, comprising a supporting platform frame 100, a cage 200, a counterweight 300, a traction motor 400, a traction wire rope 500 and an anti-slip assembly 600; the supporting platform frame 100 can be arranged in the hoistway, the traction motor 400 is arranged on the supporting platform frame 100, and the traction wire rope 500 is wound around the traction motor 400; one end of the traction wire rope 500 is connected to the cage 200, and the other end is connected to the counterweight 300; the anti-slip assembly 600 includes a tensioner 610 and a pressure sensor 620, the pressure sensor 620 is installed on the tensioner 610, the tensioner 610 is arranged on the supporting platform frame 100, and the traction wire rope 500 is wound around the tensioner 610.
[0041] Specifically, when workers use the cage 200, the traction motor 400 drives the traction wire rope 500 to move the cage 200 up and down. During the movement of the cage 200, the traction wire rope 500 is always in a taut state. At this time, the traction wire rope 500 will compress the pressure sensor 620 on the tensioner 610, so that the pressure sensor 620 can detect the pressure of the traction wire rope 500 on the tensioner 610 in real time. When the traction wire rope 500 slips off the guide wheel or other guide wheels, the pressure of the traction wire rope 500 on the tensioner 610 will change, so that the pressure sensor 620 can detect the abnormality of the traction wire rope 500, thereby alarming the staff.
[0042] A first guide wheel 120 is provided at the bottom of the supporting platform frame 100, and the traction wire rope 500 is wound around the first guide wheel 120, and the traction wire rope 500 passes through the first guide wheel 120 and is connected to the counterweight 300. A second guide wheel 140 is provided on the cage 200, and one end of the traction wire rope 500 is fixedly provided on the supporting platform frame 100, and the traction wire rope 500 can be wound around the second guide wheel 140. The traction motor 400 can drive the cage 200 to move between different floor doors 700.
[0043] Among them, both the first guide wheel 120 and the second guide wheel 140 are provided with an anti-slip plate 130 for preventing the pulling wire rope 500 from slipping off. Through the provision of the anti-slip plate 130, the pulling wire rope 500 is located in the wheel grooves of the first guide wheel 120 and the second guide wheel 140. When the pulling wire rope 500 shows signs of slipping off, that is, when the pulling wire rope 500 wants to slip off, the pulling wire rope 500 can abut against the anti-slip plate 130, and when the pulling wire rope 500 abuts against the anti-slip plate 130, the pulling wire rope 500 does not completely slip out of the wheel groove of the first guide wheel 120 or the second guide wheel 140, thereby effectively reducing the probability of the pulling wire rope 500 slipping off.
[0044] See also Figure 1 , Figure 2 and Figure 3 As shown, in an optional solution of this embodiment, a mounting seat 110 is provided on the supporting platform frame 100 , and the tensioning member 610 is installed on the mounting seat 110 .
[0045] Specifically, a mounting seat 110 is provided on the supporting platform frame 100, and a tensioning member 610 is installed on the mounting seat 110. The tensioning member 610 includes a tensioning wheel 611 and a rotating shaft 612; the tensioning wheel 611 is provided on the rotating shaft 612, and a pressure sensor 620 is provided between the tensioning wheel 611 and the rotating shaft 612. The rotating shaft 612 is installed on the mounting seat 110 by means of a U-bolt 613, and a bearing is provided between the rotating shaft 612 and the mounting seat 110. Through the above arrangement, the rotating shaft 612 can rotate freely on the mounting seat 110 along with the tensioning wheel 611.
[0046] In addition, the pressure sensor 620 is disposed between the tensioning wheel 611 and the rotating shaft 612, so that when the pulling wire rope 500 presses the tensioning wheel 611, the tensioning wheel 611 can press the pressure sensor 620, so that the pressure sensor 620 can monitor whether the pulling wire rope 500 slips.
[0047] It should be noted that there are multiple tension wheels 611 , all of which are disposed on the rotating shaft 612 , and a pressure sensor 620 is disposed between each tension wheel 611 and the rotating shaft 612 .
[0048] Finally, it should be noted that the above embodiments are only used to illustrate the technical solution of the utility model, rather than to limit it. Although the utility model has been described in detail with reference to the aforementioned embodiments, ordinary technicians in the field should understand that they can still modify the technical solutions recorded in the aforementioned embodiments, or replace some or all of the technical features therein with equivalents.
