Detailed description of the invention
Below in conjunction with the drawings and specific embodiments, the utility model is further illustrated.
As shown in Figure 1 to Figure 3, pull bar described in the utility model wears off structure with what connect bearing pin, comprises pull bar 1 and the connection bearing pin 2 for cylinder lever connecting rod 1; Also comprise and move shaft device 3, described in move shaft device 3 and comprise fixed mount 31, handwheel 32 and screw rod 33; Described fixed mount 31 is relative with the position of pull bar 1 fixing after installing; Described handwheel 32 is rotating to be arranged on fixed mount 31; One end of described screw rod 33 is fixedly connected with handwheel 32, screw rod 33 can be driven to rotate by rotating handwheel 32; Screw 4 is axially provided with, described screw 4 and above-mentioned screw rod 33 threaded engagement what connect bearing pin 2.
The effect wherein moving shaft device 3 is connection bearing pin 2 for convenience detach, and connecting bearing pin 2 can be hang the connection between 6 or the connection between pull bar 1 and gate lifting eye 7 for the connection between pull bar 1 and pull bar 1 or pull bar 1 and headstock gear.So-called fixed mount 31 is relative with the position of pull bar 1 fixing after installing, and its objective is: when rotating handwheel 32, allow screw rod 33 only rotate, and connect the movement that bearing pin 2 then occurs vertically, and then realization is to the dismounting of connection bearing pin 2.Its principle is as follows: because handwheel 32 and screw rod 33 are installed on fixed mount 31, and drives screw rod 33 to rotate by rotating handwheel 32; Again because screw rod 33 adopts threaded engagement with the screw 4 be connected on bearing pin 2; Therefore when rotating screw bolt 33, the screw rod 33 that can make be connected bearing pin 2 relative motion in the axial direction; And due to geometrical clamp 31 relatively pull bar 1 for fixing, therefore make screw rod 33 pairs of pull bars 1 can not relative movement, and then only have connect bearing pin 2 relatively pull bar 1 be moved, so just achieve the dismounting to connecting bearing pin 2.Certainly, when screw rod 33 rotates, connect bearing pin 2 can not with screw rod 33 synchronous axial system, otherwise owing to not relatively rotating between the two, its threaded engagement can not realize screw rod 33 and be connected bearing pin 2 relative movement effect in the axial direction; In general, the keyway that phase factor is set on connection bearing pin 2 is only needed can to have prevented from rotating.
Certainly, so-called fixed mount 31 is relative with the position of pull bar 1 fixing after installing; According to above-mentioned analysis, generally can fixed mount 31 be fixedly mounted on the wall corresponding with pull bar; Certainly, more preferably fixed mount 31 is directly fixedly mounted on pull bar 1.
Consider, usually when dismounting connects bearing pin 2, need connection bearing pin 2 to load completely in the pin shaft hole on pull bar 1 or take apart in pin shaft hole completely; Therefore the length of General Requirements screw rod 33 is not shorter than the length connecting bearing pin 2, and connecting bearing pin 2 so just may by complete dismounting.Certainly, in general, screw rod 33 can not be deep on pull bar 1 pin shaft hole in; Otherwise the disassemble and assemble work of pull bar 1 not only can be made more to bother, also can cause the dismounting inconvenience connecting bearing pin 2.
Why taking threaded engagement between screw 4 on connection bearing pin 2 and screw rod 33, is wish when rotating screw bolt 33, connects the relative screw rod 33 of bearing pin 2 and moves axially; Therefore in theory, screw 4 only needs one section and screw rod 33 threaded engagement, between the screw 4 of all the other area segments and screw rod 33, can matched in clearance be adopted.As screw 4 is set to the structure comprising thread segment 41 and smooth section 42, and thread segment 41 is positioned near handwheel 32 side; And thread segment 41 and screw rod 33 threaded engagement; And smooth section 42 and screw rod 33 matched in clearance.
Further, also can consider thread segment 41 to be arranged on one piece of mounting blocks 5; And smooth section 42 is arranged on connection bearing pin 2; And dismountable for mounting blocks 5 being arranged on is connected on bearing pin 2; Like this, convenient after the screw thread of thread segment 41 damages, change.As adopted screw mounting blocks 5 is installed to and connects after on bearing pin 2, once after screw thread damage in thread segment 41, not need to change whole connection bearing pin, only need to see that mounting blocks 5 wherein carries out changing; Convenient.
Certainly, the process connecting bearing pin 2 due to dismounting only needs can realize by rotating handwheel 32, and in order to avoid when dismounting connects bearing pin 2, the scope of activities connecting bearing pin 2 is limited, especially avoid connecting bearing pin 2 when mounted, excessive from screw rod 33 one end amount of penetrating, cause giving prominence to too much situation from the other end of pull bar 1.The structure of gland 34 can be set again, and gland 34 is directly installed on pull bar 1, make it hide the one end of pull bar being installed the pin shaft hole connecting bearing pin 2.Namely relative with screw rod 33 one end.Like this when connect bearing pin 2 penetrate stroke enough after, the restriction of gland 34 can be subject to, and the situation avoiding stroke excessive.
