Description
Technical field
The utility model belongs to Mechanical parking system technical field, and in particular to a kind of parking systems equilibrant force suspension centre
Structure.
Background technique
Suspension centre be lifting equipment in key component, design whether be rationally directly related to lifting equipment itself service life and
Safety when lifting；For the lifting equipments such as intelligent three-dimensional parking apparatus in lifting heavy, often design comparison is reasonable and steady
Fixed suspension centre structure, good suspension centre structure can make equipment in lifting, have many advantages, such as stress equalization, reduce lifting impact force.
Suspension centre is typically designed in the various lifting equipments such as stereo garage can only design a fixed sunpender, and sunpender one end is fixed on liter
It drops equipment or rises on weight, the other end is fixed on chain or wirerope.Lifting equipment lifting suspension centre is set at present
Meter often only uses simple pull rod, when lifting equipment is more ropes or multichain in structure, such simple pull rod meeting
Unbalance stress, and unbalance stress will lead to the wherein service life of certain root rope or chain and reduce significantly, work in three-dimensional parking device
Easily occur danger in the process, be easy to injure operator or damage equipment, vehicle.
Utility model content
In order to solve existing parking systems lifting equipment suspension centre in more ropes or multichain, rope or chain can be because of stress
Unevenness, so cause wherein certain root rope or service life of chain substantially reduce, be broken the technical problem that accident occurs, the utility model mentions
For a kind of parking systems equilibrant force suspension centre structure.
The technical solution of the utility model is:
A kind of parking systems equilibrant force suspension centre structure, is characterized in that including sunpender, suspension centre connecting plate, two
A touching bar, two suspension centre connectors, limit switch and limit switch mounting plate；The sunpender upper end and suspension centre connecting plate lower end are cut with scissors
Connect, the downrod lower end be for suspension centre structure to be mounted on the interconnecting piece on lifting device, suspension centre connecting plate upper end with
Suspension centre connector is hinged, and limit switches mounting plate is also fixedly mounted on the sunpender, and the limit switch is fixedly installed in limit
On switch installation board, touching bar is installed on the suspension centre connecting plate, the swing rod of limit switch is exactly among two touching bars；
Described two suspension centre upper end of joint are all connected with chain or wirerope.
Further, the interconnecting piece of the sunpender is threaded rod, and the interconnecting piece further includes locking nut, split pin and two
Suspension centre structure connect with lifting device by the cooperation of threaded rod, locking nut and load-bearing nut, is fixed by a load-bearing nut；
The split pin is located at the bottom of sunpender threaded rod, prevents lower section load-bearing nut when working long hours and not overhauling for a long time
It loosens and falls the engineering accidents such as cause casualties.
Further, the sunpender upper end and suspension centre connecting plate lower end are hinged by the first pin shaft, and suspension centre connecting plate can be around
First pin shaft is freely rotated in articulated position.
Further, suspension centre connecting plate upper end and suspension centre connector are hinged by the second pin shaft, and suspension centre connector can be around the
Two pin shafts are freely rotated in articulated position.
Further, the suspension centre connecting plate is small top and big bottom up-side down triangle plate, enables suspension centre connecting plate
Preferably it is connect with sunpender and suspension centre connector.
Further, it is contemplated that disconnected between the sunpender top and lower thread bar changeover portion to avoid stress from concentrating
Face area is gradually reduced, and increases the intensity of sunpender, is avoided reducing its intensity because cross-sectional area is mutated, is avoided its fracture, endanger
Danger.
Further, the wirerope uses more rope structures.It, can will rope point if every side is all made of two or more when restricting
At two groups, by each group of suspension centre dovetail connector with side respectively, it can also set multiple for the suspension centre connector, according to phase
Same mode is hinged on suspension centre connecting plate, is formed and is similar to tree-like structure.
In lifting device, driving or traction wheel drive, then or sprocket wheel pressure driving are generally forced by reel.It sets
Meter Standard General is that reel or traction wheel diameter are 40 times or more of wirerope diameter, in the design, is generally used more small straight
The resultant force lifting heavy of diameter rope, so reel or traction sheave diameter dimension can decline to a great extent, and reduce cost.
For using chain lifting, first, chain is one section of section composition, is occurred when being driven with sprocket engagement more
For side shape effect to generate noise and impact, the bigger polygon effect of chain pitch the bright existing；Second, it is important in design standard
Sprocket wheel must not be less than 17 teeth, with guarantee engagement when guarantee that enough teeth are engaged with chain.
The required torque T=F*D in driving, wherein F is load, and D is reel, traction sheave and sprocket diameter, it follows that
Torque needed for D is bigger is bigger；Torque provided by host is bigger, and main engine power will be bigger, and main shaft also will accordingly increase.
Coarse pitch chain is bound to so that sprocket diameter is larger, just may require that main engine power is higher, main shaft is bigger.
In conclusion from reasonable stress and reducing the angle of cost, minor diameter can be all used in the lifting device of heavy duty
More rope structures.
Compared with prior art, the advantages of the utility model:
1, the utility model is used between suspension centre connecting plate and sunpender by installing a suspension centre connecting plate on fixed derrick
Articulated structure, suspension centre connecting plate can be freely rotated around the first pin shaft being mounted in articulated position；It is hinged above suspension centre connecting plate
Two suspension centre connectors, suspension centre connector can be freely rotated around the second pin shaft being mounted in articulated position, and chain is connected to suspension centre
On connector, so that overall mechanism is flexible structure, rope stress equalization, the service life extension of chain or wirerope itself；
2, the utility model is using two suspension centre connectors and setting touching bar and limit switch so that certain side rope or
When person's chain breaks, the rope or chain of the other side hold lifting device, and touching bar, which touches limit switch, keeps equipment out of service, more
Add safe and reliable；
3, the utility model uses more rope structures, in same lifting heavy, promotes rope used compared to single rope structure
Diameter is small, convenient engineering installation；The size meeting when designing the key components such as corresponding traction sheave, chain hoist wheel of the hoisting rope of minor diameter
Reduce to reduce equipment cost；Especially when driving using chain hoist wheel, coarse pitch chain polygon effect is more obvious,
Noise is larger, and identical lifting condition, reduces using fine pith chain polygon effect, and noise is lower；
4, the utility model structure is simple, low in cost, and effect is prominent, has a extensive future.

Specific embodiment
Four same suspension centres can be generally used when promoting lifting device；Each suspension centre is arranged one group of the utility model；
Each suspension centre stress is roughly the same, can use biggish power as calculated value when calculating.Generally in each suspension centre of occasion of heavy duty
Two or two or more ropes can be designed to lift by crane, this is mainly in view of with the small rope of diameter and chain in design traction
When wheel, reel, sprocket wheel, when relative to using the single wire or chain that are relatively large in diameter, it is greatly decreased with size, noise
The advantages that attenuating, difficulty of processing reduce and project installation difficulty lowers.So heavily loaded rubber tyre gantry crane design is at more diameters
Lesser rope or chain are the reasonable design schemes of comparison.
It elaborates below in conjunction with attached drawing to the utility model.
