Lifting traction device

Abstract

The invention discloses a lifting traction device. The lifting traction device comprises ropes and climbing devices, wherein one ends of the ropes are fixed above a target traction site, and the climbing devices are connected with a to-be-pulled target and climb along the ropes. The climbing devices comprise front locking assemblies, rear locking assemblies and driving mechanisms for driving the front locking assemblies and the rear locking assemblies to move relatively. When the driving mechanisms drive the front locking assemblies to make displacement upwards along the ropes, the rear locking assemblies are in a locked state. When the driving mechanisms drive the rear locking assemblies to make displacement upwards along the ropes, the front locking assemblies are in a locked state. Through the arrangement, the to-be-pulled target is connected to the climbing devices, and the climbing devices rise along the ropes to drive the to-be-pulled target to rise upwards. The lifting tractiondevice is simple in structure, small in size and convenient to carry and has the low requirement for working conditions, only one ends of the ropes need to be fixed above the target traction site, andapplicability is high.

Description

technical field [0001] The invention relates to the technical field of construction engineering, in particular to a lifting traction device. Background technique [0002] Certain lifting and traction equipment is required to transport personnel and materials between the aerial work platform and the ground as well as overhaul. This kind of lifting and traction equipment also needs to take into account the actual working environment, safety and other factors. The hoisting and traction equipment in the prior art, such as: cranes, hoisting machinery, cranes, etc., is inconvenient to carry due to its own shortcomings such as complex structure, large volume and weight, and can only be used in fixed workplaces. Moreover, the layout of the traction equipment and the towed object is single, the scope of application is small, and the corresponding construction requirements cannot be met when the working conditions are complicated. [0003] Therefore, how to solve the problem that the...
