detailed description

The present invention will be further elucidated with reference to the specific drawings in order to facilitate the understanding of the technical means, the features of the invention, the objects and the advantages of the invention.

As shown in FIG. 1-5, a strong hanging and unhooking device for a brake car includes a hook device 1 and a hammer 3, wherein the lower end of the hook device 1 is provided with two claws 5, and the upper end of the hammer 3 is provided with a top end. For the tapered ram 2, the shape of the claw 5 matches the shape of the taper of the ram 2, and an umbrella guide 12 is provided at the lower portion of the shank 5 so that the ram 2 passes the umbrella guide 12 The taper head of the ejector pin 2 is conveniently inserted into the hook 5; the hook device 1 located at the upper portion of the hook 5 is provided with a wedge 4 rotatable about one end, and the wedge 4 snaps the top opening of the hook 5 The hook 5 is tightly closed; the rotatable end of the wedge 4 is connected to one end of the wire rope 13 via the guide pulley 9, and the other end of the wire rope 13 is fixed to the lower joint arm 8.

Wherein, a fixed pulley 10 is further disposed between the guiding pulley 9 and the lower joint arm 8, and the wire rope 13 passes through the fixed pulley 10 to avoid the tamper 3 moving up and down, and the length of the wire rope 13 is set according to actual process requirements, generally 10- 30 m; when the hook device 1 is raised by the set height, the wire rope 13 is tensioned, the rotatable end of the wedge 4 is pulled up, so that the wedge 4 is separated from the top opening of the claw 5, and the hammer 3 is lifted from the claw 5 by its own gravity. When the hook device 1 is lowered, the wire rope 13 is loosened, and the ram 2 is inserted into the claw 5 through the mushroom guide cover 12, and at this time, the wedge 4 is lowered by the gravity of the hook to engage the top opening of the claw 5, so that the claw 5 Close the taper of the ejector pin 3 to pull up the tamper 3.

Further, the hook 5 is further provided with a movable link 7 and a spring 6, one end of the spring 6 is connected with the top of the hook 5, and the other end is fixed on the rotating shaft of the movable link 7, and the two ends of the movable link 7 are respectively The two hooks 5 are fixedly connected to prevent the wedge 4 from falling into the opening of the upper portion of the hook 5 before the hook is lowered, so that the hook cannot be automatically hooked.

Further, by welding the nut 11 on the tamper 3, and then screwing the ejector pin 2 to the nut 11, when the ejector pin 2 is pulled up, the tamper 3 is pulled up by the nut 11, so that the ejector pin 2 can be easily removed. It is convenient to replace the corresponding ejector pins 2 according to different hooks 5.

Wherein, the bottom of the claw 5 is provided with a protrusion 14 which is in contact with the protrusion 14 when the claw 5 is closed, and an indented groove is formed on the inner and outer walls of the bottom of the claw 5, so that the ejector 2 is easy Hook and fall off.

Specifically, as shown in FIG. 2-3, when the hook device 1 is dropped to the upper end of the taper of the jack 2 on the hammer 3, the jack 2 is covered by the umbrella guide cover 12, and the hook device 1 continues to descend. During the process, the umbrella guide cover 12 guides the hook device 1 to move toward the center of the jack 2 along the taper direction of the taper of the jack 2, so that the taper of the jack 2 pushes the movable link 7 upward to drive the hook 5 The lower portion is gathered inward until the neck of the jack 2 is caught, at which time the hook 5 is opened upward, and since the wire rope on the wedge 4 is slack, the wedge 4 falls into the upper opening of the hook 5 to be the claw 5 Lock, complete the automatic hook of the tamper 3. After that, as shown in FIG. 4-5, when the hook device 1 raises and lifts the hammer 3 to the set height, the control wire rope 13 is tensioned, the movable end of the wedge 4 is pulled up, and the claw 5 is unlocked, and the hammer 3 is Automatically unhooking under the action of gravity, the hooking device 1 returns to the hook state as shown in FIG. 2; before the hooking device 1 is lowered to the automatic hook, the spring 6 presses the movable link 7 to support the lower portion of the claw 5 to remain open. In the state, the wedge 4 is prevented from falling into the opening in the upper portion of the hook 5 before the automatic hook, resulting in failure to automatically hook.

A strong twisting machine, comprising a platform and a lower arm 8, the lower arm 8 is arranged on the platform, the platform is a body of the strong twisting machine, and the lower arm 8 is provided with a strong brake automatic hanging and unhooking device, the strong The automatic hanging and unhooking device of the brake device comprises a hook device 1 and a hammer 3, wherein the lower end of the hook device 1 is provided with two claws 5, and the upper end of the hammer 3 is provided with a top rod 2 having a tapered top end, and the claw 5 The shape is matched with the shape of the taper of the jack 2, and an umbrella guide cover 12 is provided at a lower portion of the hook 5 so that the jack 2 is caught by the umbrella guide 12 when it is conveniently inserted into the claw 5 a taper head of 2; a hook device 1 located at an upper portion of the hook 5 is provided with a wedge 4 rotatable about one end, the wedge 4 snaps a top opening of the hook 5 to close the hook 5; the wedge 4 The rotatable end is connected to one end of the wire rope 13 via a guide pulley 9, and the other end of the wire rope 13 is fixed to the lower section arm 8. Wherein, a certain pulley 10 is further disposed between the guide pulley 9 and the lower joint arm 8, and the wire rope 13 passes through the fixed pulley 10 to avoid the hammer 3 moving up and down, and the length of the wire rope 13 is set according to actual process requirements, generally 10- 30 m; when the hook device 1 is raised by the set height, the wire rope 13 is tensioned, the rotatable end of the wedge 4 is pulled up, so that the wedge 4 is separated from the top opening of the claw 5, and the hammer 3 is lifted from the claw 5 by its own gravity. When the hook device 1 is lowered, the wire rope 13 is loosened, and the ram 2 is inserted into the claw 5 through the mushroom guide cover 12, and at this time, the wedge 4 is lowered by its own gravity to engage the top opening of the claw 5, so that the claw 5 Close the taper of the ejector pin 3 to pull up the tamper 3.
