Abstract

The invention discloses a highly adaptive tower crane semi-flexibility reinforcing device. The highly adaptive tower crane semi-flexibility reinforcing device comprises a fixed base, support rods, sleeves, spring hydraulic rods, fixing rods, triangular slide blocks and porous plate blocks, wherein the fixed base and the support rods are in rigid connection; the support rods are connected with one another by virtue of porous sleeves by bolts; one ends of the spring hydraulic rods and the fixing rods are hinged with the sleeves by virtue of spherical hinges, and the other ends of the spring hydraulic rods and the fixing rods are hinged with the triangular slide blocks; the triangular slide blocks are clamped to the porous plate blocks by bolts. The highly adaption of the reinforcing device is realized by changing the relative position between the sleeves and the support rods and between the triangular slide blocks and the porous plate blocks; the semi-flexibility reinforcement is realized by symmetrical support of the spring hydraulic rods and the fixing rods. According to the invention, the torque and bending moment which are caused by too high tower body or excessive load can be balanced effectively; the vibration caused by dynamic load and wind load can be eliminated; the tower body stability is improved greatly; topple accidents are prevented.

Description

A kind of flexible bracing means of tower crane half of height adaptive
Technical field
The present invention relates to tower crane technical field, specifically a kind of flexible bracing means of tower crane half of height adaptive.
Background technology
Along with the fast development of China's economic construction, adhere to tower crane and apply more and more extensive.Tower crane is in lift heavy operation process, can bear a lot of moments of torsion and bending load, when load surpasses the tolerance range of tower body, especially some occasion does not possess in the situation of the condition of adhering to, tower body meeting run-off the straight, cause tower crane integral body topple over or rupture, cause a serious accident, jeopardize the safety of personal property.Therefore, need at stacker crane body place, install semiflexible bracing means additional, improve its stability and safety.
Summary of the invention:
The object of the present invention is to provide a kind of flexible bracing means of tower crane half of height adaptive, solve stability and the safety issue of tower crane in existing technology.
The technical solution used in the present invention is: a kind of flexible bracing means of tower crane half of height adaptive, comprise firm banking, cradling piece, sleeve with holes, spring hydraulic bar, fixed link, cam block and plate with holes, it is characterized in that, described firm banking and cradling piece are rigidly connected, between cradling piece and cradling piece, by sleeve bolt with holes, be connected, spring hydraulic bar and fixed link one end are articulated with sleeve by ball pivot, the other end is articulated with cam block by ball pivot, and cam block is clamped on plate with holes by bolt.By changing sleeve and cradling piece, the relative position of cam block and plate with holes, realizes the height adaptive of bracing means.By the symmetric support of spring hydraulic bar and fixed link, realize half flexible reinforcing.
Described spring hydraulic bar and fixed link are arranged symmetrically with, are staggeredly placed, mirror image distributes, flexible and the appropriate combination of rigidity, the suffered twisting tension and compression torque of balance tower body.
Described spring hydraulic bar is spaced apart 90 degree and is arranged symmetrically with.
90 °, described fixed link and spring hydraulic bar interval are staggeredly placed, and to take two rod axis place planes of stationary links be benchmark, and mirror image is distributed in plane below.
The outstanding technique effect of the present invention is:
1, by bracing means, extend the tower body arm of force, increase moment and improve stability of tower crane body.Semiflexible reinforcing neither can cause the excessive impulsive force producing because of rigid support, also can not cause the harmonic motion producing because of resilient mounting.
2, the damping of four every layer symmetrical spring hydraulic bars can be eliminated dynamic load and wind and carries the tower body vibration causing, reduces tiredly, prevents the generation of crackle.Every layer of staggered fixed link of settling, flexibility that can regulating spring hydraulic stem is flexible, realizes half flexible reinforcing, improves stability of tower crane body.
3, the self adaptation that cradling piece connects realization height by sleeve is fixed, stable connection.Cam block is connected with the bolt of plate with holes, can regulate suitable height and angle.Improved the comformability of this bracing means, transportation, the simplicity of installing.
Accompanying drawing explanation:
Fig. 1 is the structural representation of the tower crane half flexible bracing means of height adaptive of the present invention.
Fig. 2 is the understructure schematic diagram of the tower crane half flexible bracing means of height adaptive of the present invention.
Fig. 3 is the middle level structure connection diagram of the tower crane half flexible bracing means of height adaptive of the present invention.
Parts title and sequence number in figure: firm banking 1, sleeve 2, fixed link 3, cam block 4, plate 5 with holes, spring hydraulic bar 6, cradling piece 7, taper underframe 8, the first ball pivots 9, cam block 10, plate 11 with holes, bolt 12, sleeve 13, the second ball pivots 14, bolt 15, fixed link 16, spring hydraulic bar 17, stationary links 18.
The specific embodiment:
Below in conjunction with accompanying drawing, the invention will be further described.
As shown in Figure 2 and Figure 3, the flexible bracing means of tower crane half of height adaptive of the present invention, comprises firm banking 1, sleeve 2, fixed link 3, cam block 4, plate with holes 5, spring hydraulic bar 6, cradling piece 7, taper underframe 8, the first ball pivot 9, cam block 10, plate with holes 11, bolt 12, sleeve 13, the second ball pivot 14, bolt 15, fixed link 16, spring hydraulic bar 17 and stationary links 18.Concrete structure and connection mode are:
Described taper underframe 8 is fixed on ground, and the first ball pivot 9 is articulated with on cam block 10, and the other end is fixed in taper underframe 8.Spring hydraulic bar 17 is spaced apart 90 degree and is arranged symmetrically with.Plate 11 with holes is welded on tower body, and cam block 10 is clamped on plate 11 with holes by bolt 12.
As shown in Figure 3, described sleeve 13 is connected with upper carriage bar 7 by bolt 15.Pipe link 18 is fixed on sleeve 13.Fixed link 16 and spring hydraulic bar 17 one end are articulated with sleeve 13 by the second ball pivot 14, and the other end is articulated with cam block 10 by the first ball pivot 9.90 °, fixed link 16 and spring hydraulic bar 17 interval are staggeredly placed, and to take 18 liang of rod axis place planes of stationary links be benchmark, and mirror image is distributed in plane below.
The present invention is practical, install simple, can active balance tower body too high or the excessive moment of torsion causing of load and moment of flexure, and eliminate dynamic load and wind carries the vibration causing, greatly improve stability of tower crane body, prevent from toppling over the generation of accident.
