Detailed description of the invention
Referring to figs. 1 through Fig. 5, a kind of walking dolly mechanism embodiment for extendable conveyor of the utility model is described further.
A kind of walking dolly mechanism for extendable conveyor, comprise several mutually nested frames 1, each frame 1 is installed with slide rail 3 and erecting frame 2 by bolt, erecting frame 2 on adjacent rack 1 all lays respectively at the both sides of slide rail 3, be fixedly connected on together on connecting rod by bolt between erecting frame 2, each erecting frame 2 offers a knock hole 21, a rotating shaft 4 is worn in knock hole 21, rotating shaft 4 is welded a connecting plate 5, one end that connecting plate 5 deviates from rotating shaft 4 is fixedly connected a fix shaft 6, fix shaft 6 is then installed with roller 7, roller 7 just can slide on slide rail 3, preferably between roller 7 and fix shaft 6, a self-lubricating bearing 10 is installed, such wearing and tearing that can reduce between roller 7 and fix shaft 6, extend the service life of roller 7, so just can be slided respectively in the both sides of slide rail 3 by two rollers 7 simultaneously, form a structure that slide rail 3 is clamped, increase the stability between slide rail 3 and roller 7, and then improve the stability of whole expansion box in telescopic process.
A regulating mechanism can be set respectively on the erecting frame 2 being positioned at slide rail 3 side, roller 7 is then directly enclosed within rotating shaft 4 by the erecting frame 2 of opposite side, as shown in Figure 2, regulating mechanism is conveniently roller 7, together with being used for ensureing that the roller 7 after installing to be connected to slide rail 3, joint mechanism comprises regulating plate 8, regulating plate 8 is upwards extended by connecting plate 5 and is formed, erecting frame 2 offers an adjustment hole 22, and adjustment hole 22 is positioned at the top of rotating shaft 4, adjustment hole 22 is threaded connection an adjust bar 9, together with adjust bar 9 is connected to regulating plate 8, when there is gap like this between the roller 7 after installing and slide rail 3, rotation adjusting lever 9, make adjust bar 9 one end precession towards regulating plate 8 under the effect of screw thread, and pushing regulating plate 8 forces roller 7 to be rotated down around rotating shaft 4, until together with roller 7 is connected to slide rail 3, thus the abutting that can realize between roller 7 and slide rail 3 by rotary regulating lever 9, facilitate the installation of roller 7, the position relationship between roller 7 and slide rail 3 is calculated without the need to going again in the process manufactured.
And together with the roller 7 that the roller 7 of slide rail 3 side only need be regulated can to realize both sides can be connected to slide rail 3, avoid roller 7 and occur the different high situation in the left and right sides, eliminate the situation occurring because two side wheel 7 height are uneven teetertottering, increase the stationarity of whole extendable conveyor.
Certainly, also the erecting frame 2 of both sides all can be arranged a regulating mechanism, as shown in Figure 5, also can reach same effect, not repeat herein.
In addition, adjustment hole 22 also can be arranged on the below of erecting frame 2, and now one end of adjust bar 9 can by the mode clamping connecting plate 5 of versatile spindle, and the other end is then through adjustment hole 22, pulling roller 7 and slide rail 3 to abut by outwards screwing out adjust bar 9, not repeating herein.
Consider that the pressure that adjust bar 9 is subject to when abutting with regulating plate 8 is excessive, long contact use can accelerate the wearing and tearing of adjust bar 9, thus there will be pit, the gap between roller 7 and slide rail 3 is caused to increase again, the abutting all the time between roller 7 and slide rail 3 can not be ensured, therefore a butt junction 91 can be fixedly connected with at adjust bar 9 near one end of regulating plate 8, and ensure that the sectional area of butt junction 91 is larger than the sectional area of adjust bar 9, this makes it possible to increase the area of contact between regulating plate 8 and adjust bar 9, reduce the pressure that adjust bar 9 is subject to regulating plate 8, lower the wearing and tearing of regulating plate 8 pairs of adjusts bar 9, while extending the service life of adjust bar 9, also the abutting all the time of roller 7 and slide rail 3 can be ensured further.
Certainly, a release handle 92 can also be set up at adjust bar 9 away from one end of regulating plate 8, like this in needs precession or when screwing out adjust bar 9, the rotation of adjust bar 9 can be facilitated; Also can set up one deck rubber layer 93 in butt junction 91, reduce regulating plate 8 further to the wearing and tearing abutting bar with this.
In addition, regulating plate 8 can also be arranged to trapezoidal structure, and ensure that regulating plate 8 is longer than the kidney-shaped limit 81 of opposite side away from the kidney-shaped limit 81 of adjust bar 9, the space that regulating plate 8 takies can be saved like this, effectively can ensure again the intensity of regulating plate 8, avoiding in the long-time process used, there is the situations such as fracture in regulating plate 8.
Preferably being that 50 ° of-80 ° of angle is arranged near the kidney-shaped limit 81 of adjust bar 9 and regulating plate, together with such regulating plate 8 can better be connected to adjust bar 9, be preferably 70 ° herein.
The above is only preferred implementation of the present utility model, protection domain of the present utility model be not only confined to above-described embodiment, and all technical schemes belonged under the utility model thinking all belong to protection domain of the present utility model.It should be pointed out that for those skilled in the art, do not departing from the some improvements and modifications under the utility model principle prerequisite, these improvements and modifications also should be considered as protection domain of the present utility model.
