The brake is an important part in a crane lifting system, the brake is a device with functions of decelerating, stopping or keeping a stopped state of a moving part (or a moving machine), and the like, and is a mechanical part for stopping or decelerating the moving part in the machine, and a brake block pin shaft is used for supporting a brake block in a braking process. Fig. 1 shows a schematic structural diagram of a brake block pin of a lifting brake, referring to fig. 1, the brake block pin 12 'includes a pin body 121' and annular pin fixing grooves 122 'disposed on two sides of a sidewall of the pin body 121'. Specifically, the pin body 121 ' may be, for example, a cylinder, and pin fixing grooves 122 ' are formed in the radial direction on the side wall near both ends of the cylinder, so that when the brake block is mounted on the brake arm by using the brake block pin 12 ', the ends of the fixing bolts are inserted into the pin fixing grooves 122 ' by rotating the fixing bolts provided on the brake arm, thereby limiting the axial transmission of the brake block pin 12 '. When the brake block pin shaft 12 ' is braked, the brake block pin shaft 12 ' is subjected to the action of transverse shear stress, and the brake block pin shaft is easy to break at the root of the pin shaft fixing groove 123 ', so that the hoisting safety of a casting crane is influenced.
Based on this, the utility model discloses reform transform brake block round pin axle 12, fig. 3 and fig. 4 show the schematic structure of two kinds of different embodiments of brake block round pin axle 12 after the improvement respectively, and brake block round pin axle 12 after the improvement can be applied to for example in the play to rise stopper 110 of hoist 100 for realize brake block 13 even with being connected of brake arm 11, wherein, fig. 2 shows the structure block diagram that plays to rise stopper 110 and hoist 100.
Referring to fig. 2, the hoisting brake 110 may be, for example, a main hoisting brake 110 of the crane 100, which is disposed on a crane 100 body of the crane 100 and is used for stopping or decelerating a drum 120 of the crane 100. Referring to fig. 2, the lifting brake 110 includes a brake pad pin 12, a brake pad 13 and a brake disc 14; the brake block 13 is mounted on the brake arm 11 through the brake block pin shaft 12; the brake disc 14 is disposed on a side of the brake block 13 away from the brake arm 11.
In an alternative embodiment, the lifting brake 110 may be composed of a pair of brake arms 11, a brake disc 14, and a pair of brake blocks 13 respectively disposed on the brake arms 11, wherein each brake block 13 is located between one brake arm 11 and the brake disc 14, and the brake arms 11 and the brake blocks 13 are connected by a brake block pin 12 of fig. 3 and 4 to be described later; the brake disc 14 is connected to the winding drum 120 of the crane 100 body through a rotating shaft. Thus, the distance between the brake pads 13 and the brake disc 14 is controlled by opening and closing the pair of brake arms 11, and braking is performed by friction between the brake pads 13 and the brake disc 14.
The brake shoe pin 12 of the present invention will be described with reference to fig. 3 and 4.
Referring to fig. 3, in the first embodiment, the brake shoe pin 12 includes a pin body 121, and a pin fixing hole 122 is formed on one side of a sidewall surface of the pin body 121. Specifically, the pin body 121 may be, for example, a cylinder, a pin fixing hole 122 is formed in a side wall near one side end of the cylinder, the pin fixing hole 122 extends in a radial direction of the pin body 121, and a diameter of the pin fixing hole 122 needs to be larger than a diameter of a fixing bolt to be described later, so that the end of the fixing bolt can be inserted into the pin fixing hole. When the brake block 13 is mounted on the brake arm 11 by using the brake block pin shaft 12, the position of the brake block pin shaft 12 is adjusted to align the pin shaft fixing hole 122 of the brake block pin shaft 12 with the end part of the fixing bolt arranged on the brake arm 11, so that the end part of the fixing bolt can be inserted into the pin shaft fixing hole 122 by rotating the fixing bolt, the axial fixing of the brake block pin shaft 12 is realized, and the axial movement of the brake block pin shaft 12 during braking is prevented. For example, the pin fixing hole 122 may be a circular hole, or may be a hole having another shape such as a square hole, as long as the fixing bolt can be inserted. The round hole is adopted to replace the pin shaft fixing groove 122' shown in fig. 1, and the design can effectively improve the mechanical strength of the brake block pin shaft 12, thereby reducing or avoiding the brake block pin shaft 12 of the main lifting brake 110 of the crane 100 from being easily broken and eliminating the safety risk of falling of the brake failure hanging object.
Referring to fig. 3, in this embodiment, since the pin fixing groove 122' shown in fig. 1 is replaced with a circular hole, the brake shoe pin 12 can be inserted into the pin fixing hole 122 only by rotating to a proper angle, so as to axially fix the brake shoe pin 12. For this purpose, a small hole is drilled in the middle of the sidewall of the pin body 121, and the small hole serves as a pin adjustment hole 123, and for example, a screwdriver or the like may be inserted into the pin adjustment hole 123 to rotate the brake pad pin 12, so that the pin fixing hole 122 of the brake pad pin 12 is aligned with the end of the fixing bolt provided on the brake arm 11, and thus the axial fixation of the brake pad pin 12 may be achieved by rotating the fixing bolt to insert the end of the fixing bolt into the pin fixing hole 122. As an example, a connection line between the pin fixing hole 122 and the pin adjusting hole 123 is parallel to an axial direction of the pin body 121, thereby facilitating adjustment of the position of the pin fixing hole 122. For example, the pin shaft adjustment hole 123 may be a circular hole, or may be a hole having another shape for facilitating insertion of a tool such as a screwdriver.
In this embodiment, the diameter of the pin fixing hole 122 is larger than the diameter of the pin adjusting hole 123, for example, in order to prevent the mechanical strength of the entire brake shoe pin 12 from being damaged as much as possible. It is understood that the diameter of the pin fixing hole 122 may be smaller than or equal to the diameter of the pin adjusting hole 123.
It should be noted that, in an alternative embodiment, the pin body 121 may not be provided with the pin adjustment hole 123, but the brake shoe pin 12 may be rotated by other methods, for example, a square structure may be provided at an end of the brake shoe pin 12, and a tool such as a wrench is used to rotate the brake shoe pin 12.
Fig. 4 shows a structure diagram of a second embodiment of the brake pad pin 12 of the present invention, which is compared with the first embodiment, except that the two sides of the sidewall surface of the pin body 121 are respectively provided with the pin fixing holes 122, the other structures are basically the same as the first embodiment, and therefore are not described herein. Specifically, in this embodiment, the pin fixing holes 122 on both sides of the sidewall surface of the pin body 121 are symmetrically disposed.
In conclusion, by using the lifting brake and the crane of the utility model, the hole (pin shaft fixing hole) is used for replacing the groove structure of the existing brake block pin shaft, the easy breakage of the brake block pin shaft of the main lifting brake of the crane can be reduced, and the safety risk of falling of the failed hoisted object of the brake is eliminated; by utilizing the lifting brake and the crane of the utility model, the pin shaft adjusting hole is arranged in the middle of the surface of the side wall of the brake block pin shaft, so that the position of the pin shaft fixing hole can be adjusted conveniently when the brake block pin shaft is installed, and the pin shaft fixing hole is aligned with the fixing bolt of the brake block pin shaft; the utility model discloses a play to rise stopper and hoist is rational in infrastructure, the dependable performance.
