Detailed description of the invention
Core of the present invention is to provide a kind of chassis assembly, and the connection that this chassis assembly can realize chassis and door case is reliable; Another core of the present invention is to provide a kind of high-altitude operation platform comprising above-mentioned chassis assembly.
In order to make those skilled in the art understand the present invention program better, below in conjunction with the drawings and specific embodiments, the present invention is described in further detail.
Please refer to Fig. 2 to Fig. 6.Fig. 2 is the structural representation of high and medium job platform of the present invention, Fig. 3 is the structural representation of the door case in Fig. 2, Fig. 4 is the structural representation on the chassis in Fig. 2, and Fig. 5 is the partial enlarged drawing of stay bearing plate and positioning plate in Fig. 4, and Fig. 6 is the schematic diagram that in Fig. 2, chassis and door case are connected.
A kind of chassis assembly provided by the invention, comprises chassis 10 and door case 20; Chassis 10 and door case 20 are connected to form chassis assembly by the two place's hinges up and down on vertical direction; Thus door case 20 with hinge place for axle center, to the lateral direction half-twist on chassis, can realize the action that door case 20 is opened.
Each hinge place on chassis 10, is provided with stay bearing plate 102 and positioning plate 103; Stay bearing plate 102 is arranged at the position near outside on chassis 10; And positioning plate 103 is arranged at the position near inner side on chassis 10; Meanwhile, at each hinge place of door case 20, journal stirrup 201 is provided with.
The connection mode at each hinge place is, journal stirrup 201 on door case 20 and the stay bearing plate 102 on chassis 10 and positioning plate 103 grafting, that is, journal stirrup 201 is put in the space between stay bearing plate 102 and positioning plate 103, in the space that the action radius of journal stirrup 201 is remained between stay bearing plate 102 and positioning plate 103; In addition, after grafting, journal stirrup 201, stay bearing plate 102 and positioning plate 103 three have can make anchor fitting carry out spacing hole.This means, we can use anchor fitting the three after grafting to be fixed, and make the connection at hinge place keep reliable, thus reach a case 20 and the object of the connection on chassis 10, form chassis assembly; And the action that a case 20 is opened can be realized.
The benefit of such setting is, at each hinge place, has stay bearing plate 102 and positioning plate 103 two boards to coordinate with journal stirrup 201; The Main Function that stay bearing plate 102 pairs of journal stirrups 201 play supports, and namely supports the gravity of a case 20; And the Main Function that positioning plate 103 plays carries out spacing to journal stirrup 201, thus achieve the position-limiting action of opposite house case 20.
Can find out, be arranged on the stay bearing plate 102 on chassis 10 and positioning plate 103, its objective is and the total force acting on each hinge place decomposed on two blocks of different plates, be i.e. stay bearing plate 102 and positioning plate 103.Two boards is made all to assume responsibility for component little compared with total force separately like this; Simultaneously, anchor fitting is utilized journal stirrup 201, stay bearing plate 102 to be fixedly connected with positioning plate 103 three, because above-mentioned three has been in the fixing state of relative position, therefore the application force from three that is subject to of anchor fitting is less, thus can realize connecting failure-free object.
In addition, after journal stirrup 201, stay bearing plate 102 and positioning plate 103 three grafting, on above-mentioned three, all can arrange one diameter is identical and the center of circle is in the round tube hole on same vertical line, and anchor fitting is set to the bearing pin 30 that can match with round tube hole.
Here, refer to after journal stirrup 201, stay bearing plate 102 and positioning plate 103 three grafting, fix three with bearing pin 30, guarantee after being fixedly connected with, the unlatching of a case 20 can be realized, and chassis 10 is reliable with the connection of door case 20.
Meanwhile, for the mode utilizing bearing pin 30 to fix journal stirrup 201, stay bearing plate 102 and positioning plate 103 three, we can also arrange plain cushion 301 and spring cotter 302 in the lower end of bearing pin 30.
Obviously, the object arranging plain cushion 301 and spring cotter 302 in the lower end of bearing pin 30 is, in order to make the fixation of bearing pin 30 more reliable, utilize the rubbing effect of plain cushion 301 and spring cotter 302, increase the friction force of bearing pin 30 and journal stirrup 201, stay bearing plate 102 and positioning plate 103 three, bearing pin 30 is not easily come off from above-mentioned three, thus it is reliable to ensure that chassis 10 is connected with door case 20.
Similar, we can also utilize bolt that the journal stirrup 201 after grafting, stay bearing plate 102 and positioning plate 103 are fixed connection; Meanwhile, spring washer and nut can also be set in bolt lower end.
The object of such setting and effect all with above to utilize bearing pin 30 to be fixedly connected with similar, repeat no more herein.
In addition, for the stay bearing plate 102 be arranged on chassis 10 and positioning plate 103; Distance between stay bearing plate 102 and positioning plate 103 is set to identical with the thickness of the journal stirrup 201 on door case 20.
Here, if the thickness of journal stirrup 201 just equals the distance between stay bearing plate 102 and positioning plate 103, then journal stirrup 201 puts in after between stay bearing plate 102 and positioning plate 103, journal stirrup 201 and stay bearing plate 102, all fit between journal stirrup 201 and positioning plate 103 closely, there is no unnecessary space, journal stirrup 201 can not be caused to teetertotter between stay bearing plate 102 and positioning plate 103, anchor fitting can coordinate with three closely, thus realizes chassis 10 and be connected with the reliable of door case 20.
In addition, the length of stay bearing plate 102 is set to the length being greater than positioning plate 103 by us.
By finding out above, stay bearing plate 102 and positioning plate 103, their respective effects are different, and the size of the application force that they are born separately is also not quite similar; Stay bearing plate 102 is mainly used in the gravity bearing a case 20, and the application force thus acting on himself is comparatively large, and positioning plate 103 mainly plays position-limiting action, and the application force be subject to is less.
Therefore, by the length that the length of bearing the larger stay bearing plate of application force 102 is arranged, what the length of bearing the less positioning plate of application force 103 arranged is short; This mode is their length of size decision that make use of application force suffered by two boards self; Meanwhile, the set-up mode that one is long and the other is short is also conducive to two boards and is welded on chassis 10.
In addition, for the thickness of stay bearing plate 102 with positioning plate 103, the thickness of the ratio positioning plate 103 that the thickness of stay bearing plate 102 can be arranged is thick.By mentioned earlier, from the angle that two boards is stressed, the application force that the application force that stay bearing plate 102 bears bears than positioning plate 103 is large; Therefore, the thickness of stay bearing plate 102 is greater than the thickness of positioning plate 103, is the intensity in order to make the intensity of stay bearing plate 102 be greater than positioning plate 103; Can make like this journal stirrup 201, stay bearing plate 102 and positioning plate 103 three by pin or bolt fixing after, realize chassis 10 and be connected with the reliable of door case 20.
In addition, also can the thickness of stay bearing plate 102 and positioning plate 103 be set to identical.
This set simplifies the procedure of processing of two boards; Under ensureing that stay bearing plate 102 thickness with both positioning plates 103 can meet the prerequisite of strength demand in use procedure, make both thickness identical, avoid the difference of the processing mode brought due to two kinds of different-thickness, facilitate the course of processing.
