Abstract
The utility model discloses an inner suspending combined holding rod, which comprises a rod body, a lifting device, a girdle ring and a suspending base. The inner suspending combined holding rod is characterized in that the rod body is composed of a main rod body 2 and an auxiliary rod body 4, the main rod body 2 and the auxiliary rod body 4 are connected through a cross hinged device 3, and the girdle ring 6 is located on the top of the auxiliary rod body. The main rod body of the combined holding rod can respectively rotate around an X axis and a Y axis on the hinged portion for about 20 degrees, dip angles with four surfaces of a steel tower can be adjusted arbitrarily, which is convenient for lifting tower materials, the holding rod forced condition is improved, the holding rod bending deformation and stress are eliminated, the holding rod is prevented from twisting horizontally and can lift heavier objects, and the manufacture cost and the whole weight of the holding rod are lowered.
Description
Technical field
The lifting device of the utility model belongs to Forming framework when establishing high-voltage transmission line towers erection tower material relates to a kind of inner suspension formula pole, be specifically related to be a kind of be inner suspension compound type pole.
Background technology
Inner suspended holding pole is meant that pole places the iron tower structure centre to be suspended state.Existing single lever-type inner suspended holding pole is made up of the lifting appliance 1 on a body of rod 13, body of rod top, the girdle ring 6 and the suspension base 5 of middle and lower part, as shown in Figure 7.In group tower process, earlier pole integral body is mentioned, the insertion of the bottom of pole has been organized in the upright tower section, the insertion portion of pole is the 1/3 dark of pole bottom-to-top-height, what expose 2/3 is the real work height of pole, the suspension base of pole is connected with the main material of organizing four jiaos on upright iron tower well with the support steel cable, the girdle ring of pole is connected with the main material of four jiaos on iron tower with backguy in the iron tower upper surface of having organized, top with pole is connected by the main material of four jiaos on backguy and iron tower or with ground-surface earth anchor again, at last pole is adjusted to vertical state, just can be played the tower crane material then.
The body of rod of pole when playing the tower crane material except being subjected to center pressure that deadweight of tower material and pole top backguy vertical component produced, the moment of flexure that horizontal component of force produced in addition, like this, the pole body of rod is press-bending combined deformation in the suffered distortion in girdle ring junction.Therefore, mainly there is the defective of following several respects in existing this single lever-type inner suspended holding pole: 1. the sectional area of whole pole, main material and auxilliary material specification must be consistent, otherwise the body of rod is just lost from pole girdle ring position, so its manufacturing cost is higher easily; 2. hoisting weight is little; 3. the pole own wt is too big, is unfavorable for constructing operation.
The utility model content
The purpose of this utility model is to overcome above-mentioned deficiency of the prior art, proposes a kind of inner suspension compound type pole.
The technical scheme that realizes above-mentioned purpose is: inner suspension compound type pole, the lifting appliance, girdle ring and the suspension base that comprise the body of rod, body of rod top, the described body of rod is made up of a main rod body and the secondary body of rod, the lower end of described main rod body is connected by a cross articulated mounting with the upper end of the secondary body of rod, described girdle ring is positioned at the top of the secondary body of rod of described articulated mounting below, and described suspension base is positioned at the bottom of the described secondary body of rod.
The advantage of the utility model inner suspension compound type pole has 1. main rod body can rotate about 20 ° angle respectively around X-axis, Y-axis in the hinged place, and can regulate the inclination angle of pole and four faces of iron tower arbitrarily, is convenient to lift by crane the tower material of four faces of iron tower; 2. improved the pole force-bearing situation, the secondary body of rod only bears the pressurized on its top, has eliminated flexural deformation and the stress of pole at its girdle ring place, can lift by crane heavier object; 3. the cross section of the secondary body of rod and material can reduce the manufacturing cost and the overall weight of pole less than main rod body; 4. when playing the tower crane material, the pole axis is overlapped all the time, the impossible horizontal torsion of pole with pole center of effort.
Description of drawings
Fig. 1 is the scheme drawing of making of an embodiment of the utility model;
Fig. 2 is the installation and the working state schematic representation of the utility model compound type pole;
Fig. 3 is the front view of cross articulated mounting among Fig. 1;
Fig. 4 is a cross articulated mounting lateral plan;
Fig. 5 is a cross articulated mounting birds-eye view;
Fig. 6 is the hinged front view of a kind of rigidity of Fig. 3 cross articulated mounting;
Fig. 7 is the organigram of a kind of single lever-type inner suspended holding pole of the prior art.
Among the figure: 1. lifting appliance, 2. main rod body, 3. cross articulated mounting, the 4. secondary body of rod, 5. suspension base, 6. girdle ring, 7. support steel cable, 8. girdle ring backguy, 9. articulated bracket, 10. tower material, 11. adjust rope, 12. lifting ropes, 13. bodies of rod.
The specific embodiment
Below in conjunction with accompanying drawing the utility model is further described.
As depicted in figs. 1 and 2, the utility model inner suspension compound type pole is the suspension base 5 by the lifting appliance 1 on a main rod body 2, the secondary body of rod 4, main rod body top, the girdle ring 6 on secondary body of rod top, secondary body of rod bottom, and cross articulated mounting 3 compositions that connect the main rod body and the secondary body of rod.
The erection procedure of the utility model inner suspension compound type pole is the same with the single lever-type inner suspended holding pole.Owing to adopted cross articulated mounting 3 (as Fig. 3, Fig. 4, shown in Figure 5), main pole 2 can rotate about 20 ° angle respectively around X-axis, Y-axis in the hinged place, therefore, by adjusting pole top backguy, can regulate the inclination angle of main rod body 2 and four faces of iron tower arbitrarily, the tower material of four faces of more convenient lifting iron tower.
As Fig. 6, shown in Figure 7, four angles of cross articulated mounting are provided with four rigidity articulated brackets 9, when pole needs whole setting and whole the lifting, lock four jiaos articulated bracket, make to form between the main rod body 2 and the secondary body of rod 4 and be rigidly connected the setting of the pole that promptly is convenient to operation and lifting.
Claims (2)
1. inner suspension compound type pole, the lifting appliance, girdle ring and the suspension base that comprise the body of rod, body of rod top, it is characterized in that: the described body of rod is made up of a main rod body (2) and the secondary body of rod (4), the lower end of described main rod body is connected by a cross articulated mounting (3) with the upper end of the secondary body of rod, described girdle ring (6) is positioned at the top of the secondary body of rod of described articulated mounting below, and described suspension base (5) is positioned at the bottom of the described secondary body of rod.
