DETAILED DESCRIPTION

[0030] 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.

[0031] like Figure 1-12As shown, the utility model is a drilling rig winch drum with a replaceable rope groove plate, comprising a reusable drum body 1, a left baffle plate 2 of a first specification drum, a rope groove plate 3 of a first specification drum, a right baffle plate 4 of a first specification drum, a rope groove plate fixing bolt 5, left and right baffle fixing bolts 6, a left baffle plate 7 of a second specification drum, a rope groove plate 8 of a second specification drum and a right baffle plate 9 of a second specification drum.

[0032] The first specification drum left baffle plate 2, the first specification drum rope groove plate 3 and the first specification drum right baffle plate 4 are used together and are installed on the drum body 1 through the rope groove plate fixing bolts 5 and the left and right baffle fixing bolts 6 to form a winch drum of a specification, which is used for a drilling rig winch lifting operation with a wire rope diameter.

[0033] The left baffle plate 7 of the second specification drum, the rope groove plate 8 of the second specification drum, and the right baffle plate 9 of the second specification drum are used in combination and are installed on the drum body 1 through the rope groove plate fixing bolts 5 and the left and right baffle fixing bolts 6 to form another specification of winch drum, which is used to match the drilling rig winch lifting operation with another wire rope diameter.

[0034] In this embodiment, the bottom diameter D of the first specification drum rope groove plate 3 and the second specification drum rope groove plate 8 is the same. Because the diameters of the steel wire ropes they are equipped with are different, their rope groove radii R1 and R2 are different, the spacings C1 and C2 between adjacent rope grooves are different, the number of turns of the rope grooves is different, and the total lengths L1 and L2 are different.

[0035] In this embodiment, the first specification drum rope groove plate 3 and the second specification drum rope groove plate 8 are both split and divided into two parts. They are drilled with multiple bolt mounting holes at the same position. When installed, they are concentric with the threaded holes on the drum body 1 and are installed on the drum body 1 through the rope groove plate fixing bolts 5.

[0036] In this embodiment, the left baffle plate 2 of the first specification roller and the left baffle plate 7 of the second specification roller have the same shape, but different thicknesses B1 and B2. Both are split and divided into four parts. They have multiple bolt mounting holes drilled at the same position. When installed, they are concentric with the threaded holes on the left side plate of the roller body 1 and are installed on the roller body 1 through the left and right baffle fixing bolts 6.

[0037] In this embodiment, the right baffle plate 4 of the first specification roller and the right baffle plate 9 of the second specification roller have the same shape, but different thicknesses B1 and B2. Both are split and divided into four parts. They have multiple bolt mounting holes drilled at the same position. When installed, they are concentric with the threaded holes on the right side plate of the roller body 1 and are installed on the roller body 1 through the left and right baffle fixing bolts 6.

[0038] In this embodiment, the two thickness dimensions B1 of the left baffle plate 2 of the first specification drum and the right baffle plate 4 of the first specification drum plus the length L1 of the rope groove plate 3 of the first specification drum are equal to the opening dimension L of the drum body.

[0039] In this embodiment, the two thickness dimensions B2 of the left baffle plate 7 of the second specification drum and the right baffle plate 9 of the second specification drum plus the length L2 of the rope groove plate 8 of the second specification drum are equal to the opening dimension L of the drum body.

[0040] The opening size L of the drum body 1 remains unchanged. Since the rope groove radius and the rope groove pitch of the first specification drum rope groove plate 3 and the second specification drum rope groove plate 8 have different values, when the rope grooves are both integer circles, the length L1 of the first specification drum rope groove plate 3 and the length L2 of the second specification drum rope groove plate 8 are also different. By adjusting the thickness sizes B1 and B2 of the left and right baffles, after the drum rope groove plate and the left and right baffles are installed, the length of the drum rope groove plate plus the thickness of the left and right baffles are the same as the opening size of the drum body 1, thereby ensuring that rope groove plates of different specifications can be installed on the same drum body 1, and realizing the universality of the drum body for steel wire ropes of different specifications.

[0041] 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. In addition, the technical solution of the utility model is limited only by the scope of the claims.

[0042] Finally, it should be pointed out that the above embodiments are only representative examples of the present utility model. Obviously, the present utility model is not limited to the above embodiments, and there are many variations. Any simple modification, equivalent changes and modifications made to the above embodiments based on the technical essence of the present utility model shall be considered to belong to the protection scope of the present utility model.
