Specific implementation mode
Below in conjunction with the accompanying drawings, the utility model is described in detail.
In order to make the purpose of the utility model, technical solutions and advantages more clearly understood, below in conjunction with attached drawing and implementation
Example, the present invention will be further described in detail.It should be appreciated that specific embodiment described herein is only used to explain
The utility model is not used to limit the utility model.
The protective device that a kind of garbage crane of the utility model is grabbed bucket is carried out with reference to concrete structure and principle detailed
Explanation.
A kind of protective device of garbage crane grab bucket, as shown in Figure 1, Figure 2, Figure 3 shows, the protective device includes central tube 1,
The barrel outside of several spokes 2, protection ring 5 and cushion pad 6, the central tube 1 is provided with several faggings I 3, the guarantor
Retaining ring 5 is the ring-shaped structure concentric with central tube 1, and inside is provided with several faggings II 4, and the spoke 2 is located at center
Between cylinder 1 and protection ring 5, both ends offer groove I and groove II respectively, and are fixed on respectively by groove I and groove II
On fagging I 3 and fagging II 4, the cushion pad 6 is fixed on the outside of protection ring.
In the utility model protective device, central tube 1 is hollow cylinder-like structure, for the dynamic cunning in crane grab bucket
Wheel group transmits the load of grab bucket, bears the shock loading of the transmission of spoke 2, the flange face of the flange face and crane grab bucket of central tube 1
It is consistent, realizes the safety for ensureing original structure while installation.Spoke 2 transmits and disperses for fixing protection ring 5
The impact load that protection ring 5 is subject to；Protection ring 5 bears grab bucket and the impact in pool wall collision process for fixing cushion pad 6
Load；Cushion pad 6 works as a buffer, and reduces grab bucket and the shock loading in pool wall collision process, while rubber pad also rises actively
Protective effect, when grab bucket collides and scrapes with pool wall, cushion pad 6 is destroyed prior to rubbish pool wall, to protect pond
Wall, therefore the needs of cushion pad 6 inspect periodically replacement.In addition, better protecting effect in order to obtain, the extension of entire protective device
(i.e. cushion pad 6) should be more bigger than the extension that garbage crane is grabbed bucket when opening, and specifically, the length of spoke should ensure that 5 He of protection ring
The range that circumferentially covers of cushion pad 6 is more than the range that the beginning is opened in grab bucket.
Several faggings I 3 are provided on the outside of the barrel of central tube 1, the inside of protection ring 5 is provided with several faggings II 4,
Fagging I 3 and fagging II 4 be used for realizing the fixation to spoke 2, can by way of welding procedure with central tube 1 and protection ring 5
It is connected and fixed.The both ends of spoke 2 offer groove I and groove II respectively, and are fixed on fagging by groove I and groove II respectively
I 3 and fagging II 4 on.The structure that spoke one end opens up groove is as described in Figure 4, and the other end uses identical groove structure form, only
It is that the groove of the other end and the groove of diagram are vertically arranged in 90 degree, the depth of groove is determined according to calculating.Using spoke 2
Both ends open up groove, and fagging is welded in groove, can ensure that device satisfaction makes with the connectivity robustness between reinforcing member
With requiring.
Central tube 1, fagging I 3, spoke 2, fagging II 4 and protection ring 5 material be preferably low-alloy steel, and using weldering
The mode connect is fixedly connected, it is ensured that the integral strength and rigidity of protective device.Spiral shell is used between protection ring 5 and cushion pad 6
It tethers and connects, facilitate the replacement of cushion pad 6.
Further, the cushion pad 6 is rubber pad.Rubber pad can play the role of buffering well, reduce grab bucket and pond
Shock loading in wall collision process, while rubber material is wear-resisting, invulnerability is preferable, and ambient adaptability is strong, more meets rubbish
The operating environment requirement of crane handgrip.
Further, the protection ring 5 is C-shaped semicircular configuration.Using C-shaped semicircular configuration, protective device is increased
Protection domain, ensure that the stability of entire protective device structure, the convenient connection with cushion pad, at the same increase protective device with
The contact surface of concrete-pool-wall, reduces impact load.
Further, the spoke 2 is steel pipe.Spoke 2 uses seamless steel pipe, the rigidity and intensity of seamless steel pipe all directions equal
Preferably, the stability to protection ring 5 can be enhanced.
Further, the fagging I 3, fagging II 4, the number of spoke 2 are identical.In order to make the structure of entire protective device more
Add stabilization, generally using fagging I 3, fagging II 4,2 one-to-one form of spoke.
Further, the fagging I 3 is evenly distributed on the outside of the barrel of central tube 1, and the fagging II 4 is evenly distributed on guarantor
The inside of retaining ring 5.Equally distributed structure design can further increase the structural integrity of protective device.Further, institute
It is six to state fagging I 3, and fagging II 4 is six, and spoke 2 is six.The number that fagging I 3, fagging II 4 and spoke 2 are can root
It is selected and is set according to specific use demand, stablized entire protective device as long as can play, protection ring 5 is propped up
The purpose of support.Preferred six of the utility model, and using uniformly dividing otherwise, realizing whole device fastness
The weight for further decreasing device simultaneously, to which it is reduced to minimum to the lifting loading effect of garbage crane grab bucket.
Further, several bolts are provided on the flange face that the upper bottom surface of the central tube 1 circumferentially extends outside
Hole 7.For bolt hole 7 for realizing that the installation of protective device is fixed, the flange face and the flange face of crane grab bucket of central tube 1 keep one
It causes, protective device is fixed between crane running block and grab bucket ontology by bolt.
The utility model protective device is with grab bucket scheme of installation as shown in figure 5, specifically, in crane grab bucket ontology and moving
Install the utility model protective device between pulley blocks additional.Protective device is absolute construction, convenient to overhaul, dismounting and change；Protection dress
It sets and the structure for not destroying original grab bucket is connect using the bolt consistent with original structure between original grab bucket, do not influence original
The safety of structure；Protective device is installed in garbage crane grab bucket top, does not influence the operating status of garbage crane grab bucket；Protection
Device extension is more bigger than the extension that garbage crane is grabbed bucket when opening, and is no more than the safe distance of garbage crane grab bucket and pool wall, no
Influence the range of operation of garbage crane grab bucket；Protective device is light-weight, accounts for about the 1~2% of original lifting load, has little influence on
The lifting load of garbage crane grab bucket.
The above is only the preferred embodiment of the utility model only, is not intended to limit the utility model, all at this
All any modification, equivalent and improvement etc., should be included in the utility model made by within the spirit and principle of utility model
Protection domain within.
