DETAILED DESCRIPTION

[0019] The technical solution of the utility model will be described clearly and completely below in conjunction with the accompanying drawings. Obviously, the described embodiments are part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments of the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0020] like Figure 1-2 As shown, a winch drum fixing device of the utility model is used to fix the winch drum body 6, including a seat plate 1, a vertical plate 2 and an ear plate 3. The seat plate 1 and the vertical plate 2 are fixedly arranged on the winch skid seat 7. One end of the ear plate 3 is rotatably arranged on the seat plate 1, and the other end is matched and connected with the vertical plate 1 or the drum body 6.

[0021] In this embodiment, the ear plate 3 includes two parallel side plates 31, and the middle parts of the two side plates 31 are connected by two connecting plates 32, and the connecting plates 32 are perpendicular to the side plates 31; after the side plates 31 and the connecting plates 32 are connected into a whole, a first opening groove 33 is formed at one end, and a second opening groove 34 is formed at the other end.

[0022] In this embodiment, the first opening groove 33 is rotatably connected to the seat plate 1 via the first connecting mechanism 4 .

[0023] In this embodiment, the first connection mechanism 4 includes a first pin shaft 41, a first safety pin 42 and a first washer 43. A through pin shaft hole is provided on the two side plates 31 of the first opening slot 33. After the first opening slot 33 is inserted into the seat plate 1, the limiting cap at one end of the first pin shaft 41 abuts against the outer side of the side plate 31 on one side, and the other end of the first pin shaft 41 passes through the pin shaft hole, so that the ear plate 3 and the seat plate 1 are rotatably connected together. A limiting hole is provided at the end of the first pin shaft 41, and the first safety pin 42 passes through the limiting hole to limit the position and prevent the first pin shaft 41 from jumping out. Both ends of the first pin shaft 41 are provided with a first washer 43 to prevent hard contact.

[0024] In this embodiment, the second opening slot 34 is connected to the vertical plate 2 via a second connecting mechanism 5 .

[0025] In this embodiment, the structure of the second connection mechanism 5 is similar to that of the first connection mechanism 4, including a second pin shaft 51, a second safety pin 52 and a second washer 53. A through pin shaft hole is provided on the two side plates 31 of the second opening slot 34. After the second opening slot 34 is inserted into the vertical plate 2, the limiting cap at one end of the second pin shaft 51 abuts against the outer side of the side plate 31 on one side, and the other end of the second pin shaft 51 passes through the pin shaft hole to connect the ear plate 3 and the vertical plate 2 together. A limiting hole is provided at the end of the second pin shaft 51, and the second safety pin 52 passes through the limiting hole to limit the position and prevent the second pin shaft 51 from jumping out. Second washers 53 are provided at both ends of the second pin shaft 51 to prevent hard contact.

[0026] like Figure 3 As shown, when the winch drum body 6 does not need to be fixed, the ear plate 3 of the fixing device is flipped to the side of the vertical plate 2 and the ear plate 3 is fixed by the second connecting mechanism 5 .

[0027] When the winch drum body 6 needs to be fixed, the ear plate 3 of the fixing device is flipped to the side of the drum body 6. A plurality of pin connecting holes 61 are drilled on the drum body 6. The drum body 6 is manually rotated to make the nearest pin connecting hole 61 on the drum body 6 concentric with the pin hole of the ear plate 3. The second pin 51, the second washer 53 and the second safety pin 52 are inserted to fix the drum body 6, thereby preventing the drum body 6 from rotating without brake fixation, thereby ensuring the safety of people and equipment.

[0028] It should be noted that the description of the above technical solutions is exemplary, and this specification can be embodied in different forms and should not be interpreted as being limited to the technical solutions set forth herein. On the contrary, providing these descriptions will make the disclosure of the utility model thorough and complete, and will fully convey the scope disclosed in this specification to those skilled in the art.
