Abstract
The utility model discloses a gantry type hydraulic jacking device, relating to hoisting machinery and solving the problems of a clamping jack jacking device that the section is adverse to the working at heights and base sections have short service life. The gantry type hydraulic jacking device comprises a jacking support frame and multiple gantry base sections connected with the jacking support frame, and is characterized in that a hydraulic elongator is arranged on the jacking support frame, the hydraulic elongator is connected with a steel strand, the other end of the steel strand is connected with a lifting eye of the hydraulic elongator, gantry base section lifting eyes are arranged on the lower parts of the gantry base sections, and the hydraulic elongator lifting eye is connected with the gantry base section lifting eyes. The gantry type hydraulic jacking device has the advantages of simple structure, light weight, low manufacture cost, and stable and rapid jacking motion.
Description
Technical field
The utility model relates to elevator machinery, particularly the jacking apparatus of gantry type hydraulic hanging equipment.
Background technology
The gantry type hydraulic lifting apparatus is mainly by mast structure, cable wind rope, slinging beam, bont, form from installation system and control system.As shown in Figure 1, what generally use now from installation system is a kind of clamping jack jacking apparatus, and existing jacking apparatus comprises: jacking bracing frame 1, and with jacking bracing frame 1 bonded assembly more piece door frame base section 3.It is to adopt to clamp the square steel that jack 7 clamps door frame base section 3, through clamping the stroke action of jack, reaches jacking, the installation of whole door frame base section.The shortcoming of prior art: the one, the cross section of door frame base section is the square-section, because the wind area of square-section is bigger, is unfavorable for aloft work; The 2nd, the clamping jack clamps repeatedly and loosens base section square steel surface, makes the lost of life of base section.The 3rd, the surface special processing of base section square steel, expense increases.
Summary of the invention
The purpose of the utility model is exactly the shortcoming to prior art, and a kind of gantry type hydraulic jacking device is provided, and solves the existing jacking apparatus that adopts the clamping jack, because the door frame base section is the square-section, is unfavorable for aloft work; Clamp the square steel surface repeatedly owing to clamp jack, influence base section service life; The surface special processing of base section square steel, the problem that expense increases.
The utility model is realized through following technical scheme:
A kind of gantry type hydraulic jacking device; Comprise: the jacking bracing frame, and with jacking bracing frame bonded assembly more piece door frame base section, it is characterized in that: on said jacking bracing frame, tensioning jack is installed; Said tensioning jack is connected with steel strand; The other end of said steel strand is connected with the tensioning jack hanger, is provided with door frame base section hanger in the said door frame base section of every joint bottom, and said tensioning jack hanger is connected with said door frame base section hanger.
The utility model compared with prior art owing to adopt tensioning jack to substitute the clamping jack, through the folding and unfolding steel strand of tensioning jack, reaches jacking, the installation of door frame base section.The utlity model has simple in structure, in light weight, low cost of manufacture, jacking stable action, fast speed advantage.
Description of drawings
Fig. 1 is the prior art constructions scheme drawing;
Fig. 2 is the structural representation of the utility model.
The utility model is further described through embodiment below in conjunction with accompanying drawing.
The specific embodiment
As shown in Figure 2, a kind of gantry type hydraulic jacking device comprises: jacking bracing frame 1, and with jacking bracing frame 1 bonded assembly more piece door frame base section 3; Tensioning jack 2 is installed on said jacking bracing frame 1; Said tensioning jack 2 is connected with steel strand 5; The other end of said steel strand 5 is connected with tensioning jack hanger 4; Be provided with door frame base section hanger 6 in the said door frame base section of every joint 3 bottoms, said tensioning jack hanger 4 is connected with said door frame base section hanger 6.
The working process of the utility model:
The first step after jacking bracing frame 1 and 3 installations of door frame base section, is fixed in tensioning jack 2 on the jacking bracing frame 1 and connects steel strand 5 and tensioning jack hanger 4;
In second step, tensioning jack hanger 4 is connected with door frame base section hanger 6;
The 3rd step, tensioning jack 2 actions, steel strand 5 move up with tensioning jack hanger 4, and drive door frame base section hanger 6 moves up with door frame base section 3 and reaches the jacking purpose.
