Embodiment Construction
[0018] A non-anchor point self-propelled crane sliding handling method for large components with limited hoisting conditions, the specific steps are as follows:
[0019] Step 1: First make a pair of herringbone carrying masts or portal masts.
[0020] The chevron handling mast stand as figure 1 , figure 2 As shown, it includes a pair of herringbone steel mast frames 1-1 arranged in the same direction, two side-by-side fixed pulleys installed on the top of each steel mast frame respectively, and the fixed pulleys respectively sleeved on the front fixed pulley 2a and the rear fixed pulley 2b. The front pull steel rope and the back pull steel rope are respectively connected to the drag hook 5 at the bottom of the front pull steel rope and the back pull steel rope. The length of the front pull steel rope is greater than the length of the back pull steel rope. The length of the steel rope can be adjusted.
[0021] The portal mast frame as image 3 , Figure 4 As shown, it inc...

The invention discloses a hoisting condition limited large component anchor-point-free self-push suspension sliding carrying method which comprises the steps that a pair of carrying mast racks is manufactured and is erected on the two sides of the front part and the rear part of a to-be-moved article, and pull hooks at the bottom ends of a front-pull steel rope and a rear-pull steel rope on the carrying mast racks are correspondingly hooked on hoisting points at the front part and the rear part of the to-be-moved object; the front-pull steel rope and the rear-pull steel rope are tightened, andthe front-pull steel rope and the rear-pull steel rope are locked after the to-be-moved object gets off the ground and is in a suspension state; then, the carrying mast racks are pulled in the direction opposite to the forward moving direction of the object, so that the object moves forward; when the object slowly falls back to the ground during forward movement, operators stop pulling the steelmast racks, and the front-pull steel rope and the rear-pull steel rope are released so that the object moves forward by a certain distance and then falls on the ground; and the operation is carried out in this way repeatedly till the object is carried in place. In low space where the hoisting operation height is limited or on a construction plant having no mechanical hoisting condition due to ground hardening, the heavy and large object can be carried in a time-saving and labor-saving manner with the adoption of the method.
Description
technical field [0001] The invention belongs to the technical field of methods for moving and transporting large components at building construction sites, in particular to the method for moving and transporting large components under conditions of limited height. Background technique [0002] In the installation and construction of heavy and large objects, it is necessary to use hoisting equipment to lift and carry these heavy and large components. However, in some places limited by the height of hoisting operations or when the ground hardening does not meet the conditions for the use of hoisting machinery, hoisting equipment cannot be used, and only manual handling can be relied on. Not only is the handling difficult, time-consuming and laborious, the operation efficiency is extremely low, and there are potential safety hazards. Contents of the invention [0003] The purpose of the present invention is to solve the deficiencies of the prior art and provide a method for t...
