For the lever 2 for driving push rod 3 to move, one end of lever 2 is hinged end, and the other end of lever 2 is mobilizable Free end, hinged end is hinged with the second end, and free end is connected with lockable mechanism.It should be noted that those skilled in the art All it should be understood that lever 2 should also include balance pivot 11.It is further to note that those skilled in the art should Being apparent from said apparatus needs to remove the cylinder body of checking cylinder before the use.
Comparing content is introduced with background technology, in technique scheme, the dismounting of locomotive brake cylinder piston release spring Device, using lever principle, significantly reduces the labor intensity of operator, while carrying out locking by using pin to lever Positioning so that release spring in compressive state when can keep stable, it is to avoid the spring that anthropic factor causes collapses the danger for Danger, so as to ensure safety of employees, improves job safety coefficient.In addition, after using the device, when changing spring operation Between relatively before shorten 3 hours, and easy to operate.
In particular embodiments, also include the guider 9 for preventing release spring 5 from bending when compressing, be oriented to Device 9 is set in the outside of release spring 5.There is bending during by arranging the guider and can place spring-compressed.Certainly It is understood that above-mentioned setting guider is only the preferred citing of the embodiment of the present invention, can also be and be not provided with leading To device, push rod is directly connected with the bottom of leading screw 4, and connected mode can be connected using screw thread, or people in the art The conventional connected mode that conveniently can dismantle of member.
In further embodiment, leather cup 8 and the guider of checking cylinder are slidably matched, and leather cup is located at first end Between portion and leading screw 4.It should be noted that those skilled in the art should be appreciated that leather cup is a part for checking cylinder, And generally leather cup is contacted with leading screw or is connected, and is moved with leading screw.Tight with the inwall of guider by above-mentioned leather cup It is slidably matched, first end abuts promotion leather cup motion with leather cup, and then leather cup promotes guide screw movement.By sliding with guider The dynamic leather cup for coordinating so that when the first end of push rod drives guide screw movement, more stable.Of course, it should be understood that may be used also In the way of the first end for being above-mentioned push rod is directly fixedly connected with leading screw.Only the embodiment of the present invention is preferably using above-mentioned The mode of leather cup is set.
In further technical scheme, guider 9 can be fixedly connected with brake cylinder head 7, the side being fixedly connected Formula can be the mode of seccotine bonding or threaded mode, and such as guider is that tubular, remaining brake cylinder head is fixed One end be provided with external screw thread, brake cylinder head to should external screw thread be provided with above-mentioned external screw thread coordinate tapped blind hole.Certainly It is understood that the above-mentioned mode being fixedly connected is only the preferred citing of the embodiment of the present invention, on-fixed is can also be The mode that the end face of the mode of connection, such as guider is abutted with brake cylinder head.
For locating rod and pin that above-mentioned lockable mechanism includes to be connected with free end, pin is used for entering locating rod Row locking is positioned.Can be specifically pin-and-hole to be provided with locating rod 12, the pin-and-hole is passed through by pin, and is fixed on relatively Locking positioning is carried out on the static object in face.It is appreciated of course that above-mentioned locating rod with the lockable mechanism of pin is only One kind of the embodiment of the present invention is preferably illustrated, and can also be other lockable mechanisms that those skilled in the art commonly use, such as thick stick The free end of bar is connected with bracing wire, is arranged at intervals with suspension ring in bracing wire, by suspension ring to be fixed on the hook of relative ground static On carry out locking positioning etc..
In specific implementation process, when being located in by the way of the pin-and-hole in locating rod 12 using pin 1, in pin-and-hole Wall is also provided with lines, can prevent coming off for pin 1 by lines.Lock can be increased further due to arranging lines Coefficient of friction on the contact surface of the pin-and-hole on position pin and locating rod, so as to avoid the potential safety hazard that coming off occurs in pin. It is appreciated of course that one kind that the mode of above-mentioned setting lines is only the embodiment of the present invention is preferably illustrated, can also be Make pitted skin or other can be in the way of increasing the coefficient of friction of contact surface.Above-mentioned locating rod 12 can adopt channel-section steel, or ability Other shaped steel that field technique personnel commonly use, as the rigidity of shaped steel is more stable so that device is not variable during life-time service Shape.
More specifically, above-mentioned lines is preferably dimensioned to be 0.3cm.Of course, it should be understood that above-mentioned 0.3cm is only this Inventive embodiments are preferably illustrated for one kind of texture size, can also be other sizes.
In further preferred embodiment, the movement travel allowed by the hinged end of lever 2 is made more than the maximum of release spring 5 Dynamic stroke.Larger by the ratio for arranging the movement travel of one end of lever drives pushrod movement, can achieve release spring pressure It is reduced to range.Due to release spring compression bigger, pin 6 is bigger with the gap of brake cylinder head, taking-up just more square Just.Will be understood be can also be mode that is identical with the maximum braking distance of release spring or being slightly less than, as long as can Departed from brake cylinder head with realizing pin 6, pin can take out.
Still more preferably in embodiment, the movement travel of the hinged end of above-mentioned lever is made than the maximum of release spring 5 The big 0.5cm of dynamic stroke.It is appreciated of course that the numerical value of above-mentioned 0.5cm is only a kind of preferable examples of the embodiment of the present invention , can also be other numerical value.
In addition, the embodiment of the present invention can provide a kind of method of locomotive brake cylinder piston release spring dismounting, including step Suddenly:
Step 1:Fixing brake cylinder head 7, after positioning, brake cylinder head will not be moved with the motion of leading screw or release spring;
Step 2:Release spring 5 is promoted using leverage and makes release spring 5 that compression motion is done, lever force is caused Lever drives pushrod movement, push rod promotes guide screw movement, and as release spring one end is by the backstop of brake cylinder head, the other end is with silk Thick stick is moved, and then release spring occurs compression motion;
Step 3:When release spring 5 is moved to pin 6 and is separated with brake cylinder head, locking positioning lever mechanism, make lever Keep under the state and take out pin 6;
Step 4:Release the locking to leverage to position and make release spring 5 recover to naturalness;
Step 5:The positioning action of the positioner 10 of unloading brake cylinder head 7, removes brake cylinder head 7, takes out release spring 5.
