The specific embodiment
Describe below with reference to the accompanying drawings and in conjunction with the embodiments the utility model in detail.Need to prove, in the situation that do not conflict, embodiment and the feature among the embodiment among the application can make up mutually.
To shown in Figure 10, according to first embodiment of the present utility model, provide a kind of connecting device such as Fig. 8, comprised two attaching partss 10 and be used for clamping the locating part 20 of two attaching partss 10.
Two attaching partss 10 are oppositely arranged, and the two ends of each attaching parts 10 are provided with the connecting bore 11 that connects bearing pin be used to wearing, and one of them connects the otic placode that bearing pin is used for hinged crane arm 40, and another connects bearing pin and is used for hinged amplitude draw-bar 30.
Locating part 20 comprises the first limiting section 21, the first limiting section 21 is positioning plate, this positioning plate comprises the first plate body 212, the second plate body 213 and the 3rd plate body 214, wherein the first plate body 212 and the second plate body 213 are oppositely arranged, the 3rd plate body 214 is connected between the first end of the first end of the first plate body 212 and the second plate body 213, makes the position-limited trough 211 that is formed for clamping two attaching partss 10 between the first plate body 212, the second plate body 213 and the 3rd plate body 214.Position-limited trough 211 has clamping space, and two attaching partss 10 are fixed in this clamping space.
Here the effect of locating part 20 is the relative distance for two attaching partss 10 of restriction, and is inside and outside mobile to prevent that two attaching partss 10 from occuring, and causes its unbalance stress.
For fear of the otic placode interference of locating part 20 with crane arm 40, the degree of depth of position-limited trough 211 will adapt with the path of motion of crane arm 40.
Here the first limiting section 21 is not limited to platy structure, can be block structure also, as long as have the groove that can clamp two attaching partss 10.
In the present embodiment, the first limiting section 21 has two, and two the first limiting sections 21 are oppositely arranged.Certainly, the quantity of the first limiting section 21 is not limited to two here, should arrange according to actual needs.
Because attaching parts 10 is the platy structure of steel matter, and the material of the first limiting section 21 is different from the material of attaching parts 10, if attaching parts 10 and the first limiting section 21 direct weld togethers can be reduced the structural strength of attaching parts 10, so the second limiting section 22 of steel matter need to be set between the first limiting section 21 and attaching parts 10, with the first limiting section 21 and the second limiting section 22 weld togethers, and with the second limiting section 22 and attaching parts 10 weld togethers, the first limiting section 21 is captiveed joint with attaching parts 10 by the second limiting section 22, thereby avoid attaching parts 10 and the first limiting section 21 direct solder togethers and destroy the performance of attaching parts 10.
And, adopt this structure, can be at the scene distance between according to actual needs the attaching parts 10, select suitable locating part 20, thereby can improve the comformability that connecting device connects amplitude draw-bar 30 and crane arm 40.
In the present embodiment, the second limiting section 22 comprises two column structures, the second end weld together of the periphery wall of a column structure and the first plate body 212, the periphery wall of another column structure is captiveed joint with the second end of the second plate body 213, the end face of two column structures all with 10 welding of corresponding attaching parts.
Here the quantity of column structure is not limited to two, should arrange according to actual needs.Column structure also is not limited to be arranged on the end of the first plate body 212 or the second plate body 213, is connected as long as can be respectively be connected with attaching parts with the first limiting section 21.
Attaching parts 10 also has and a plurality of column structures a plurality of knock holees one to one, can limit the position of each column structure on attaching parts 10 before welding, makes welding effect better.
According to second unshowned embodiment of the present utility model, a kind of connecting device is provided, comprise two attaching partss 10 and be used for to clamp the locating part 20 of two attaching partss 10.Here locating part 20 is list structure, captives joint with two attaching partss 10 respectively in the two ends of this list structure, the effect that changes to play the distance that prevents two attaching partss 10.
Preferably, the fixed form of locating part 20 and two attaching partss 10 is welding.In order to prevent between locating part 20 and two attaching partss 10 causing affecting weld strength because material is different, can between locating part 20 and two attaching partss 10, be welded with the member identical with attaching parts 10 materials, to increase the firm intensity of welding.
Preferably, locating part 20 is column structure or platy structure.
According to another embodiment of the present utility model, a kind of arm tower crane is provided, comprise amplitude draw-bar 30, crane arm 40 and be connected to amplitude draw-bar and the otic placode of crane arm between connecting device, this connecting device is aforementioned any connecting device.
Two kinds of the regular structure of the otic placode of crane arm 40 and irregular structures, when otic placode is regular texture, owing to not needing to consider the interference between otic placode and the locating part 20, so locating part 20 can adopt second list structure among the embodiment, the connecting device integral structure is simple like this, and assembling is than being easier to.
When otic placode is regular texture, owing to needing the interference between consideration otic placode and the locating part 20, so locating part 20 needs to adopt the structure with position-limited trough 211 among first embodiment, can avoid like this interference between the member, makes arm tower crane work more smooth and easy.
From above description, can find out, the utility model the above embodiments have realized following technique effect: by limit the relative distance between two attaching partss with locating part, the otic placode of attaching parts and crane arm is clamped, can prevent that the gap between attaching parts and the otic placode from changing, make connection more safe and reliable, increased the connection safety of amplitude draw-bar and crane arm.And this locating part is simple in structure, so that the connecting device integral installation is convenient.
The above is preferred embodiment of the present utility model only, is not limited to the utility model, and for a person skilled in the art, the utility model can have various modifications and variations.All within spirit of the present utility model and principle, any modification of doing, be equal to replacement, improvement etc., all should be included within the protection domain of the present utility model.
