Abstract
The invention discloses a vertical shock absorber structure with a lifting function. The vertical shock absorber structure with the lifting function comprises a lifting ring seat assembly, wherein a connection rod is installed on the lower part of the lifting ring seat assembly, a downward telescopic dustproof cover is installed on the outer circumferential surface of the connection rod, guide seat assemblies of two groups of adjustment valves which are symmetrically arranged are installed on the connection rod located at the lower end of the telescopic dustproof cover, a piston assembly is installed at the bottom of the connection rod, steps are arranged on the connection rod located on the upper part of the piston assembly, and a stopper is fixed at each step through a steel cable baffle ring; and each guide seat assembly structurally comprises a guide seat fixed on the connection rod through a sealing device, an adjustment hole is formed in each guide seat, an adjustment seat is installed in each adjustment hole through an O-shaped sealing ring, an adjustment nut is installed at the top of each adjustment seat, a spring seat is arranged at the bottom of each adjustment seat, an adjustment spring is installed in each spring seat, a valve element is further installed at the bottom of each adjustment hole, and an oil return tube is further comprised, and connected with an oil return hole of the corresponding guide seat. The vertical shock absorber structure with the lifting function plays a role of protecting a shock absorber.
Description
Technical field
The present invention relates to absorber technical field, especially a kind of vertical damper structure with hoisting function.
Background technique
At present, vibration damper is widely used, according to the needs of client, in a lot of application, needs to adopt the vibration damper having hoisting function and require.
Vibration damper of the prior art does not have hoisting function, lift by crane time, vibration damper is stretched, piston assembly due to be subject to hoisting weight produce active force can damage.
Summary of the invention
The applicant, for the shortcoming in above-mentioned existing production technology, provides a kind of vertical damper structure with hoisting function rational in infrastructure, thus improves operational safety, protection piston assembly.
The technical solution adopted in the present invention is as follows:
A kind of vertical damper structure with hoisting function, comprise rings seat assembly, the bottom installing connecting rods of described rings seat assembly, the outer peripheral surface of described connecting rod installs downward Telescopic dustproof cover, the connecting rod being positioned at Telescopic dustproof cover lower end is provided with the guide holder assembly of symmetrically arranged two groups of modulating valve, piston assembly is installed in the bottom of described connecting rod, and the connecting rod being positioned at piston assembly top is provided with step, and described step place is fixed with backstop by Steel Cable Baffle Ring; The structure of described guide holder assembly is: comprise the guide holder be fixed on by seal arrangement on connecting rod, adjustment hole is had in described guide holder, by O-ring seals, adjustment seat is installed in described adjustment hole, adjusting nut is installed at the top of described adjustment seat, the bottom being positioned at adjustment seat is provided with spring seat, and install Regulation spring in described spring seat, the bottom being positioned at adjustment hole is also provided with spool, also comprise return tube, described return tube connects the spill port of guide holder.
Beneficial effect of the present invention is as follows:
Compact structure of the present invention, rationally; the connecting rod of piston assembly upper end is installed hoisting stopper device; when lifting by crane; vibration damper is stretched to maximum; owing to adding stop device; avoid the impact of the active force that piston assembly produces because of hoisting weight and damage, serving the effect of protection vibration damper.
The present invention adopts two guide holder assembly, good damping result, and operational safety is good, meet the usage requirement of different application occasion, can be applicable to the application of various different nonlinear dampling feature request, when reaching certain effect power, the modulating valve in two guide holder can also play the effect of off-load.Use flexibility is good.
Accompanying drawing explanation
Fig. 1 is structural representation of the present invention.
Fig. 2 is the partial enlarged drawing in A portion in Fig. 1.
Wherein: 1, rings seat assembly; 2, Telescopic dustproof cover; 3, connecting rod; 4, guide holder; 5, adjustment hole; 6, adjusting nut; 7, adjustment seat; 8, O-ring seals; 9, spring seat; 10, spool; 11, return tube; 12, backstop; 13, Steel Cable Baffle Ring; 14, piston assembly.
Embodiment
Below in conjunction with accompanying drawing, the specific embodiment of the present invention is described.
As depicted in figs. 1 and 2, the vertical damper structure with hoisting function of the present embodiment, comprise rings seat assembly 1, the bottom installing connecting rods 3 of rings seat assembly 1, the outer peripheral surface of connecting rod 3 is installed downward Telescopic dustproof cover 2, the connecting rod 3 being positioned at Telescopic dustproof cover 2 lower end is provided with the guide holder assembly of symmetrically arranged two groups of modulating valve, piston assembly 14 is installed in the bottom of connecting rod 3, the connecting rod 3 being positioned at piston assembly 14 top is provided with step, and step place is fixed with backstop 12 by Steel Cable Baffle Ring 13; The structure of guide holder assembly is: comprise the guide holder 4 be fixed on by seal arrangement on connecting rod 3, adjustment hole 5 is had in guide holder 4, by O-ring seals 8, adjustment seat 7 is installed in adjustment hole 5, adjusting nut 6 is installed at the top of adjustment seat 7, the bottom being positioned at adjustment seat 7 is provided with spring seat 9, and install Regulation spring in spring seat 9, the bottom being positioned at adjustment hole 5 is also provided with spool 10, also comprise return tube 11, return tube 11 connects the spill port of guide holder 4.
When lifting operation, along with the effect of parts gravity of slinging, under the effect of stop device, vibration damper can be stretched to maximum, and bear certain active force, if do not have hoisting stopper or hoisting stopper to lose efficacy, so just likely can damage vibration damper inner body, cause vibration damper the performance failure even generation of oil leakage phenomenon.
More than describing is explanation of the invention, and be not the restriction to invention, limited range of the present invention, see claim, within protection scope of the present invention, can do any type of amendment.
