Abstract
The utility model discloses an anti-falling steering column in construction machinery. The anti-falling steering column comprises an orientation column and a pipe component, wherein a shifting fork is mounted at the tail end of the steering column; a connector is arranged at one end of the pipe component; a through hole perpendicular to a central axis of the connector is formed in the connector; hollow cylindrical bosses are formed on the outer walls of two ends of the through hole; the pipe component is inserted into the shifting fork and fixes the connector through a nut, a screw and the cylindrical bosses; and pins are mounted on the cylindrical bosses. According to the steering column, pins are added on the basis of a conventional nut fixing shifting fork and a connector, so that potential safety hazards caused by nut falling due to long time vibration and failure of a thread adhesive are effectively avoided, a nut and the pipe component can be connected reliably, and the safe and stable operation of a whole orientation machine is guaranteed.
Description
Technical field
The utility model relates to a kind of construction machinery and equipment slip-off preventing Steering gear, belongs to construction machinery and equipment safety method field.
Background technology
In traffic cost more and more higher today, the wheeled machine of construction machinery and equipment is favored by the user more and more, but because its service conditions is abominable, dust and greasy dirt have been full of, and for home-made machine, the problem that ubiquity vibrations are bigger, therefore, the intensity of its core-Steering gear be connected tightness and just require higher; In its connection structure, nut is its desirable design point by being threaded with the pipe assembly, leans on the friction force on plane to guarantee that nut can rotate arbitrarily and not withdraw from by a part of pipe assembly under the rotation of universal-joint.The assurance operating personal can be regulated the inclination angle, front and back of whole direction machine in order to best serviceability is arranged by handle like this.
Traditional fixing means is to coat screw thread glue in the thread surface of nut, slowly tightens again, moves the pipe assembly after dry 36 hours again under state of nature, and it is qualified that rotation does not have interference to be, but but has following problem:
1) screw thread glue is anaerobic adhesive, and its dry degree of depth can only guarantee under normal conditions below 10mm, but the degree of depth herein is about 30mm, and screw thread glue can not solidify fully under normal conditions, so can there be friction relatively in nut between them when rotating with the pipe assembly.
2) the working environment very severe of construction machinery and equipment, dust, greasy dirt have been full of, and vibrations are very big, though this Steering gear is outside body seal is arranged, can produce the gap under the situation of long-term vibration, dust will enter, nut can be increasing under the dust environment with the relative motion of pipe assembly, nut will withdraw from the pipe assembly, and this not only makes the front and back of direction machine regulate and goes wrong, and can occur that whole direction machine leans forward suddenly or the safety problem of hypsokinesis.
The utility model content
The purpose of this utility model is: a kind of construction machinery and equipment slip-off preventing Steering gear is provided, only fixes the problem that causes nut to come off easily by the nut that is coated with screw thread glue to solve traditional Steering gear.
The technical solution of the utility model:
A kind of construction machinery and equipment slip-off preventing Steering gear, comprise that end is equipped with the pipe assembly that the direction post of fork, an end are provided with connector, offer a through hole perpendicular to the connector axis on the described connector, the connector outer wall at these through hole two ends also is provided with the cylinder boss of hollow, and described pipe assembly inserts in the fork and by nut, screw rod and cylinder boss connector is fixed; On the described cylinder boss pin is installed.
Described pin is spring cotter.
Described direction post is provided with universal-joint with the junction of pipe assembly.
The beneficial effects of the utility model:
Compared with prior art, the construction machinery and equipment slip-off preventing Steering gear that the utility model provides, it has fixedly installed pin additional in the basis of fork and connector at traditional nut, efficiently solve because of long-term vibration and the screw thread glue potential safety hazard that the nut that causes comes off and produce that lost efficacy, make nut can reliably be connected with the pipe assembly, guaranteed the safe and stable operation of whole direction machine.
Description of drawings
Fig. 1 is structural representation of the present utility model;
Fig. 2 is dotted portion enlarged drawing among Fig. 1;
Among the figure: 1-direction post, the 2-universal-joint, the 3-fork, the 4-nut, the 5-pin, the 6-connector, 7-manages assembly, 8-cylinder boss.
The specific embodiment
Below in conjunction with accompanying drawing the technical solution of the utility model is described further, but that desired protection domain is not limited to is described;
As shown in Figure 1, 2, the construction machinery and equipment slip-off preventing Steering gear that the utility model provides, it comprises that end is equipped with the pipe assembly 7 that the direction post 1 of fork 3, an end are provided with connector 6, offer a through hole perpendicular to connector 6 axis on the described connector 6, connector 6 outer walls at these through hole two ends also are provided with the cylinder boss 8 of hollow, and described pipe assembly 7 inserts in the fork 3 and by nut 4, screw rod and cylinder boss 8 fixes connector 6; On the described cylinder boss 8 pin 5 is installed.
In order to prevent coming off and losing efficacy of pin 5, described pin 5 is spring cotter.
In order to realize the angular adjustment between direction post 1 and the pipe assembly 7, direction post 1 is provided with universal-joint 2 with the junction of pipe assembly 7.
