Description

TECHNICAL FIELD

[0001] The present application relates to the technical field of joint fastening structure of high-speed rail bogie bolster, and particularly relates to a mounting and dismounting device suitable for a joint fastened on a high-speed rail bolster screw sleeve. BACKGROUND

[0002] A common joint fastening structure is used on the current high-speed rail bogie bolster, which fastens a steel screw sleeve with inner and outer threads on the bolster air vent first, and then fastens the air pipe joint on the bolster. The structure effectively protects the aluminum alloy structure of the bolster by using a steel transition screw sleeve, avoiding damage to the bolster caused by repeated dismounting of the joint. However, the disadvantage is that if the steel screw sleeve is not held firmly during dismounting of the joint, the screw sleeve can be loosened together, and if the loosened screw sleeve is reinstalled, it increases the risk of damage to the bolster and also violates the original intention of using a steel screw sleeve to avoid frequent fastening that causes damage to the bolster.

[0003] Currently, the method of dismounting the joint is to use a wrench to hold the steel screw sleeve during loosening of the joint, but this method has certain disadvantages. First, it cannot ensure that the screw sleeve is held firmly during dismounting of the joint, and second, the operator may not be able to detect slight rotation of the screw sleeve during operation.

[0004] Therefore, based on the above technical problems, there is an urgent need in the art for a mounting and dismounting device suitable for a joint fastened on a high-speed rail bolster screw sleeve. SUMMARY

[0012] The joint is above the steel nut, and the nut tightening wrench is arranged below the joint dismounting wrench according to the relative position of the steel nut and the joint.

[0013] Further, the driving structure comprises:

[0014] A handle; and

[0015] A double-thread stud connected below the handle;

[0034] In order to make the technical scheme of the embodiments of the present application or the prior art clearer, the accompanying drawings needed in the embodiments will be briefly introduced as follows. Obviously, the accompanying drawings in the following description only show some embodiments of the present application, and other drawings can also be obtained by those skilled in the art based on these drawings.

[0035] Referring to Figs. 1-2 as shown in the drawings;

[0036] The installation and dismounting device of the joint fastened on the high-speed rail sleeper beam screw sleeve in the embodiments of the present application comprises: a driving structure; and a screw sleeve tightening wrench 6 and a joint dismounting wrench 7 in transmission connection with the driving structure, and the screw sleeve tightening wrench 6 is matched with the steel screw sleeve 2, and the joint dismounting wrench 7 is matched with the joint 3.

[0037] The driving structure drives the screw sleeve tightening wrench 6 and the joint dismounting wrench 7 to rotate towards opposite directions and respectively applies opposite rotating forces to the steel screw sleeve 2 and the joint 3 through two connecting arms.

[0038] Specifically, the mounting and dismounting device for the joint 3 fastened on the high-speed rail sleeper beam screw sleeve comprises a screw sleeve tightening wrench 6 matched with the steel screw sleeve 2 mounted on the sleeper beam 1, and a joint dismounting wrench 7 matched with the joint 3 mounted on the steel screw sleeve 2; secondly, the driving structure capable of synchronously driving the screw sleeve tightening wrench 6 and the joint dismounting wrench 7 to rotate is designed, and since it is necessary to ensure that the steel screw sleeve 2 and the joint 3 rotate in opposite directions, the driving structure of the embodiment synchronously drives the screw sleeve tightening wrench 6 and the joint dismounting wrench 7 to rotate in opposite directions through two connecting arms, so that the steel screw sleeve 2 and the joint 3 are driven to rotate in opposite directions with the same torque, which can not only dismount the joint 3, but also ensure that the steel screw sleeve 2 is not loosened.

[0039] Based on the structure of the steel screw sleeve 2 and the joint 3 on the sleeper beam 1 in the prior art, the sleeper beam 1 of the embodiment is connected with the steel screw sleeve 2 through threads, and the steel screw sleeve 2 is connected with the joint 3 through internal threads;

[0040] The joint 3 is located above the steel screw sleeve 2, and the screw sleeve tightening wrench 6 is arranged below the joint dismounting wrench 7 according to the relative position of the steel screw sleeve 2 and the joint 3.

[0041] Preferably, the driving structure of the embodiment comprises a handle 4; and a double-threaded stud 5 connected below the handle 4;

[0042] The double-threaded stud 5 is divided into two threaded sections, and the threaded rotation directions of the two threaded sections are opposite.

[0043] In order to synchronously drive the two wrenches to rotate in opposite directions through the driving structure, the double-threaded stud 5 is adopted in the embodiment, that is, the threaded spiral direction of one section of the stud is opposite to that of the other section. Thus, the linear motion of the nut in different directions is realized through the opposite threaded direction matched with the nut, and finally the two wrenches are driven to rotate in different directions.

[0044] The two connecting arms of the embodiment are respectively a tightening wrench connecting arm 801 rotationally connected with the screw sleeve tightening wrench 6, and a dismounting wrench connecting arm 802 connected with the joint dismounting wrench 7;

[0045] The two threaded ends are respectively a first threaded section and a second threaded section;

[0046] The tightening wrench connecting arm 801 is threadedly connected with the first threaded section through a first nut 901, and the dismounting wrench connecting arm 802 is threadedly connected with the second threaded section through a second nut 902.

[0047] The screw direction of the inner thread of the first nut 901 and the inner thread of the second nut 902 is opposite. Based on the rotating direction of the steel sleeve 2 and the joint 3 and the direction needed to be rotated during the dismounting of the joint 3, the first threaded part is formed at the lower part of the double-threaded stud 5, and the second threaded part is formed at the upper part of the double-threaded stud 5;

[0048] The one end of the tightening wrench connecting arm 801 is hinged to the first nut 901, and the other end is hinged to the end of the sleeve tightening wrench 6;

[0049] The one end of the dismounting wrench connecting arm 802 is hinged to the second nut 902, and the other end is hinged to the end of the joint dismounting wrench 7.

[0050] During the work, the steel sleeve 2 is first tightened by the sleeve tightening wrench 6, and the joint 3 is tightened by the joint dismounting wrench 7. After the two wrenches are tightly fastened, the handle 4 is rotated. At this time, with the rotation of the double-threaded stud 5, the two nuts are farther and farther away due to the opposite rotation direction, thereby driving the two connecting arms to move, and the two wrenches are pushed in the opposite direction by the connecting arms, so that the joint 3 and the steel sleeve 2 are subjected to almost equal opposite torsion during the entire dismounting of the joint, and the torsion of the steel sleeve is almost zero. By this method, the loosening of the steel sleeve caused by the torsion during the dismounting of the joint can be avoided.

[0051] In the above technical solution, the installation and dismounting device provided by the application for the joint fastened on the high-speed rail sleeper beam sleeve has the following beneficial effects:

[0052] The installation and dismounting device of the application can overcome the dependence on personnel technical level and psychological quality caused by the method of relying on manpower and operator experience to ensure the tightening of the steel sleeve during the dismounting of the joint, and eliminate the possibility of loosening the steel sleeve during the dismounting of the joint.

[0053] The above only describes some exemplary embodiments of the application by way of illustration, and it is needless to say that those skilled in the art can modify the described embodiments in various ways without departing from the spirit and scope of the application. Therefore, the above figures and description are illustrative in nature and should not be understood as limiting the scope of protection of the claims of the application.
