A tension rope pressing type rope climbing device comprises a guide wheel, a rope wheel, a pressing wheel, a power mechanism and a bottom plate and further comprises a tension rope pressing device. The tension rope pressing device comprises a lever obliquely spanning the two sides of the center of the rope wheel, a rope generates tension through the guide wheel, the tension is transmitted to the pressing wheel through the lever, and the pressing wheel compresses the rope in a rope groove under the torque of the lever. According to the tension rope pressing type rope climbing device, the tension of the rope is ingeniously utilized and transmitted to the pressing wheel through the guide wheel and the lever obliquely spanning the two sides of the center of the rope wheel, the pressure of thepressing rope can dynamically track the change of load gravity, the pressure is in a small magnitude during the light load, and therefore abrasion of the rope can be reduced; and the pressure is automatically increased during the heavy load, and the proportion of two force arms of the lever is properly set, so that enough rope pressing pressure can be obtained, and the rope climbing device is prevented from slipping. By means of the scheme, the structure of the rope climbing device is greatly simplified, and the rope climbing device has the remarkable advantage of being low in manufacturing cost.
一种张力压绳式爬绳器,其包括导轮、绳轮、压轮、动力机构以及底板,还包括一个张力压绳装置,该装置包括一个杠杆,它斜跨在绳轮中心的两侧,绳索通过导轮产生张力,张力通过杠杆传递给压轮,压轮受到杠杆的力矩压紧绳槽中的绳索。该爬绳器巧妙利用了绳索的张力,并通过导轮和斜跨在绳轮中心两侧的杠杆传递给压轮,压绳的压力能够动态跟踪负载重力的变化,当轻载时该压力处于较小量值,有利于降低绳索的磨损,当重载时该压力自动增大,适当设置杠杆两个力臂的比例,就能获得足够的压绳压力,避免爬绳器打滑。该方案还大大简化了爬绳器的结构,具有制造成本低的显著优势。
