In which, for a more detailed description of the structure thereof, a description will be given of the counterweight assembly 1 including a counterweight rotating shaft 101 at a furnace body fixing position and a rotating arm 102 rotatably connected to the counterweight rotating shaft 101, the rotating arm 102 being rotatable about the counterweight rotating shaft 101.

As shown in fig. 1-4, another more detailed embodiment of a split type traction roller counterweight cylinder opening device is described below, and the split type traction roller counterweight cylinder opening device comprises a counterweight assembly 1, a switching assembly 2 and a driving assembly 3, wherein the driving assembly 3 pushes the switching assembly 2 to move, so that the counterweight assembly 1 is driven to rotate to automatically open the counterweight 103 of the split type traction roller. The counterweight assembly 1 includes a counterweight rotating shaft 101 at a furnace body fixing position and a rotating arm 102 rotatably connected to the counterweight rotating shaft 101, the rotating arm 102 being rotatable about the counterweight rotating shaft 101.

In use, the nut 1042 is rotated to a position far away from the counterweight 103, then the counterweight 103 is moved to a required position, and the nut 1042 is rotated to enable the nut 1042 to be extruded to the left side and the right side of the counterweight 103, so that the counterweight 103 is fixed. The driving arm 1021 and the driven arm 1022 are connected to form an L shape, the counterweight rotating shaft 101 is rotationally connected to the corner position of the L shape, the driving arm 1021 and the driven arm 1022 are integrally formed, the counterweight rotating shaft 101 is taken as a fulcrum, and when the driving arm 1021 rotates around the counterweight rotating shaft 101, the driven arm 1022 also rotates around the counterweight rotating shaft 101, so that the counterweight 103 can be opened in a moving manner. In order to realize rotation of the driving arm 1021, in this embodiment, the driving assembly 3 pushes the switching assembly 2 to drive the driving arm 1021 to rotate, the switching assembly 2 includes a switching arm 201 and a contact seat 202, one end of the switching arm 201 is connected with the driving arm 1021, and the other end is connected with the contact seat 202, so that the switching assembly 2 and the rotating arm 102 are connected into a whole to perform synchronous movement. The contact base 202 and the driving arm 1021 are located at different positions in the transverse space, and although the contact base 202 and the driving arm 1021 move synchronously, the contact base 202 guides the driving assembly 3 to other positions, and enough space is provided for installing the driving assembly 3 to drive the contact base 202 to move, and the driving arm 1021 is driven to rotate through the switching arm 201. The driving assembly 3 comprises a base 301, an air cylinder 302, a support 303 and a roller 304, wherein the fixed end of the air cylinder 302 is arranged on the base 301, the telescopic end of the air cylinder 302 is connected with the support 303, the roller 304 is arranged on the support 303 through a pin shaft 305, the roller 304 can rotate on the support 303, the air cylinder 302 can drive the support 303 to move along the extending direction of the telescopic end of the air cylinder 302 when being extended, and the roller 304 rolls on the surface of a contacted component without being blocked. When the cylinder 302 is extended, the roller 304 contacts the contact seat 202, and the movement track of the roller 304 has a movement component perpendicular to the contact seat 202, the movement component perpendicular to the contact seat 202 of the roller 304 causes the movement of the contact seat 202, and the movement of the contact seat 202 drives the driving arm 1021 to rotate, so that the driven arm 1022 also rotates, thereby achieving the purpose of opening the counterweight 103.

In some embodiments, the mounting surface of the base 301 for mounting the air cylinder 302 is inclined relative to the bottom surface of the base 301, and an angle is formed between the extension direction of the air cylinder 302 and the contact base 202, so that when the air cylinder 302 extends, a movement component perpendicular to the contact base 202 and a movement component parallel to the contact base 202 can generate a movement component perpendicular to the contact base 202, the movement component perpendicular to the contact base 202 can drive the contact base 202 to move, and the movement component parallel to the contact base 202 can cause the roller 304 to roll on the surface of the contact base 202, namely, the relative position of the telescopic end head of the air cylinder 302 and the contact base 202 is changed, but due to the existence of the roller 304, sliding friction is changed into rolling friction, so that friction is reduced, and blocking is prevented. The included angle between the extension direction of the cylinder 302 and the driving arm 1021 is an obtuse angle, and the included angle between the extension direction of the cylinder 302 and the driving arm 1021 is continuously reduced due to the fact that the angle of the driving arm 1021 is continuously changed in the moving process, and the included angle between the extension direction of the cylinder and the driving arm 1021 is an obtuse angle, so that the included angle change allowance is reserved.

In some embodiments, when the cylinder 302 is in the retracted state, the roller 304 is separated from the contact base 202, and when the contact base 202 is in the vertical state, i.e., when the cylinder 302 is in the retracted state, the roller 304 is completely separated from the contact base 202, and the driving assembly 3 does not affect the normal operation of the counterweight 103. As for the extension length of the cylinder 302 in operation, it is possible to design in advance so as to be able to push the opening weight 103 to the destination position.

In some embodiments, the water cooling jacket 306 is installed outside the cylinder 302, so the cylinder 302 has lower operating requirements and longer service life.

Thus, various embodiments of the present disclosure have been described in detail. In order to avoid obscuring the concepts of the present disclosure, some details known in the art are not described. How to implement the solutions disclosed herein will be fully apparent to those skilled in the art from the above description.

Although some specific embodiments of the present disclosure have been described in detail by way of example, it should be understood by those skilled in the art that the above examples are for illustration only and are not intended to limit the scope of the present disclosure. It will be understood by those skilled in the art that the foregoing embodiments may be modified and equivalents substituted for elements thereof without departing from the scope and spirit of the disclosure.
