Abstract
A kind of bolt mechanism, be made up of bearing pin, ball, spring and spring dynamics adjusting portion, the front side inner sleeve of described bearing pin has spring, and the upper end of spring connects ball, and the lower end of spring connects the spring dynamics adjusting portion for regulating ball height; The front side of described bearing pin is provided with perforate, described ball and perforate suitable.The utility model, by the dynamics of Regulation spring, makes ball be placed in above bearing pin, carries out the assembling of crane component part, thus ensure that crane component part assembling is faster, and easy accessibility, the component after dismounting not easily drop.
Description
Technical field
The utility model relates to hoist technical field, is particularly applied to a kind of bolt mechanism of wheel mounted crane.
Background technique
Wheel mounted crane is the swing arm revolving crane utilizing tyre type chassis to walk.It is the Full Rotary hoist of one jack machinism is arranged on the special chassis of scale-up version tire and wheel shaft composition, its superstructure and crawler crane are substantially identical, the stability of fuselage during in order to ensure installation exercise, hoist is provided with four telescopic supporting legs.Smooth ground can be carried out little initial weight lifting without supporting leg and hang thing low speed driving.Bolt mechanism is one of important spare part in wheel mounted crane assembly process, because bolt mechanism can play the effect of positioned zero parts.
Existing bolt mechanism mainly adopts following three kinds of structures: the first adopts the combination of straight pin 2 and bearing pin 1 to carry out component to be mounted with (see Fig. 1); The second adopts the combination of cotter pin 3 and bearing pin 1 to carry out component to be mounted with (see Fig. 2); The third adopts the combining form of β type spring pin 4 and bearing pin 1 to carry out component to be mounted with (see Fig. 3).But it is inconvenient that the defect that these three kinds of modes exist is bolt-dismounting, making crane component part not quick when assembling, waste time and energy, and the component after dismounting easily dropping.
Model utility content
It is the bolt mechanism overcoming the deficiencies in the prior art and provide a kind of easy accessibility that the utility model obtains object, make crane component part very quick when assembling, and the component after dismounting not easily drops.
The technological scheme that the utility model solves is: a kind of bolt mechanism, be made up of bearing pin, ball, spring and spring dynamics adjusting portion, the front side inner sleeve of described bearing pin has spring, and the upper end of spring connects ball, and the lower end of spring connects the spring dynamics adjusting portion for regulating ball height; The front side of described bearing pin is provided with perforate, described ball and perforate suitable.
Further, described spring dynamics adjusting portion is screw.
Further, the external thread diameter of described screw is identical with the external diameter of spring.
Further, described screw is sunk screw, socket head screw or round head bolt.
Further, described screw is made up of wing nut and bolt.
Further, described spring dynamics adjusting portion is plectane.
Further, described plectane is by welding manner and pinned connection.
Further, the diameter of described plectane is identical with the external diameter of spring.
The beneficial effects of the utility model:
(1) by the dynamics of screw Regulation spring, ball is made to be placed in above bearing pin, carry out the assembling of crane component part, thus ensure that crane component part assembling is faster, and turn on the dynamics of screw Regulation spring a little, ball is fallen in bearing pin bolt mechanism to be pulled down, very convenient, and the component after dismounting not easily drop;
(2) by the dynamics of welding plectane Regulation spring, ball is made to be placed in above bearing pin, carry out the assembling of crane component part, thus ensure that crane component part assembling is faster, by plectane is removed the adjustment that spring dynamics is carried out in welding, ball is fallen in bearing pin bolt mechanism to be pulled down, very convenient, and the component after dismounting not easily drop.

Embodiment
Embodiment 1
As shown in Figure 4: a kind of bolt mechanism, be made up of bearing pin 1, ball 5, spring 6 and spring dynamics adjusting portion, spring dynamics adjusting portion is screw 7; The front side inner sleeve of bearing pin 1 has spring 6, and the upper end of spring 6 connects ball 5, the lower end attachment screw 7 of spring 6; The external thread diameter of screw 7 is identical with the external diameter of spring 6, makes screw 7 can withstand spring 6 and is unlikely to produce dislocation.Screw 7 is socket head screw, and the front side of bearing pin 1 is provided with perforate, and ball 5 is suitable with perforate.
In the process of tightening screw 7, Compress Spring 6 is carried out by spanner, part or all making ball 5 is placed in above bearing pin 1 through perforate, carry out the assembling of crane component part, thus ensure that crane component part assembling is faster, and in the process of turning on screw 7 dynamics of Regulation spring 6, spring 6 is upheld, thus ball 5 is fallen in bearing pin 1 bolt mechanism can be pulled down, very convenient, and the component after dismounting not easily drop.
Embodiment 2
Be with the difference of embodiment 1, screw 7 is made up of wing nut and bolt.By with hand-screw pine or screw the dynamics that wing nut carrys out Regulation spring, carry out adjustment more convenient and quicker compared in embodiment 1 with spanner or screw-driver.
Because the present embodiment it will be appreciated by those skilled in the art that, so do not represent with other accompanying drawing again.
Embodiment 3
As shown in Figure 5: the difference of the present embodiment and embodiment 1 is, spring dynamics adjusting portion is plectane 8, and the diameter of plectane 8 is identical with the external diameter of spring 6, and make plectane 8 can withstand spring 6, plectane 8 is connected with bearing pin 1 by welding manner.
Compress Spring 6 is carried out by welding plectane 8, part or all making ball 5 is placed in above bearing pin 1, carry out the assembling of crane component part, thus ensure that crane component part assembling is faster, the adjustment of spring 6 dynamics is carried out by plectane 8 being removed welding, ball 5 is fallen in bearing pin 1 bolt mechanism to be pulled down, very convenient, and the component after dismounting not easily drop.
