Description

Technical Field

[0001] This utility model belongs to the field of winch technology, and in particular relates to a folding cable winch. Background Technology

[0002] Geophysical exploration winches are widely used in engineering projects to lower cables and downhole instruments during logging operations. However, due to the complex environments of some geophysical exploration projects, traditional manual mechanical transmission winches are still used in most situations. In actual work, personnel have certain requirements for the height of the winch handle when collecting data, and there are also certain requirements for the height of the winch disc above the ground in complex ground conditions. Existing mechanical foot-tilting winches use screws and circlips for limiting and fixing the foot-tilting function, which is not easy to operate in low-light environments. Therefore, a cable winch that can quickly fix the foot-tilting mechanism is needed. Summary of the Invention

[0003] To solve the above-mentioned technical problems, this utility model provides a folding cable winch.

[0019] The technical solution of this utility model is further described below, but the scope of protection is not limited to what is described.

[0020] Example:

[0021] like Figures 1 to 4 As shown, a folding cable winch includes a winch and a locking structure. The locking structure includes a male buckle 7, a female buckle 8, and a fixed sliding piece 9. One end of the male buckle 7 is connected to a support leg 6 of the winch, and the other end is connected to one end of the female buckle 8. The other end of the female buckle 8 is connected to the support leg 6 of the winch. The fixed sliding piece 9 is slidably connected to the outer wall of the male buckle 7 and the female buckle 8. Both the male buckle 7 and the female buckle 8 are connected to the support leg 6 through an annular connecting part, allowing the male buckle 7 and the female buckle 8 to rotate around the support leg 6 along the axis of the annular connecting part, or to slide on the support leg 6.

[0022] Both male buckle 7 and female buckle 8 are made of flexible steel sheets, possessing a certain degree of flexibility. Through the cooperation of limit block 10 and support leg 6, support leg 6 can be positioned appropriately during winch operation. At this time, support leg 6 is located below the winch, providing support. Through the cooperation of the pin of male buckle 7 and the fixing hole of female buckle 8, the fixing slide 9 is moved to the connection point of male buckle 7 and female buckle 8 for fixation, preventing support leg 6 from tipping over due to the weight of the winch. During winch transportation, the fixing slide 9 is moved to male buckle 7 or female buckle 8, so that it is no longer located at the connection point of male buckle 7 and female buckle 8. Then, support leg 6 is flipped up, and through the cooperation of the pin of male buckle 7 and the other fixing hole of female buckle 8, the fixing slide 9 is moved to the connection point of male buckle 7 and female buckle 8 to lock support leg 6. At this time, support leg 6 is located above the winch, occupying less space. The center of gravity of the folding cable winch is lowered, preventing the folding cable winch from tipping over during transportation due to its high center of gravity.

[0023] The winch also includes a mounting flange 1, a drive shaft 2, a crank handle 3, a support column 11, a first gear 14, and a cable winding assembly. Two mounting flanges 1 are provided and connected by the support column 11. The support column 11 is hinged to the support leg 6. Both ends of the drive shaft 2 are connected to the mounting flange 1 through bearings. One end of the drive shaft 2 passes through the mounting flange 1 and is connected to the crank handle 3. The drive shaft 2 passes through the first gear 14 and is connected to the cable winding assembly.

[0024] The cable winding assembly includes a cable retainer 12 and a roller 13. The cable retainer 12 is disposed on both sides of the roller 13. The diameter of the cable retainer 12 is larger than the diameter of the roller 13 to prevent the cable from coming off from both sides of the roller 13. The drive shaft 2 passes through the cable retainer 12 and the roller 13 to form a connection.

[0025] A secondary shaft 4 is mounted on the mounting flange 1, and a second gear 5 is connected to the secondary shaft 4. The second gear 5 meshes with the first gear 14. The crank handle 3 can be detached and installed on the main shaft 2 and the secondary shaft 4 to switch the drive shaft. When the main shaft 2 drives the drum 13, the winding speed is fast, but more force is required to rotate the main shaft 2. When the secondary shaft 4 drives the drum 13 to wind up the wire, the second gear 5 meshes with the first gear 14, achieving a more labor-saving but slower winding speed. Different winding speeds are achieved by using gears with different numbers of teeth. The second gear 5 is made of metal, and the first gear 14 is made of nylon to reduce weight.

[0026] Four supports 11 are arranged in parallel. Two limiting blocks 10 are respectively installed on the two parallel supports 11 closest to the support leg 6. The limiting blocks 10 extend downward from the support 11 to limit the rotation angle of the support leg 6. In use, the support leg 6 is simply flipped to the position where it contacts the limiting block 10, which puts the winch into working condition. The size of the support leg 6 can be set in advance to ensure that the winch is at an optimal working height.

[0027] The fixed slide plate 9 is provided with a sliding groove 15, and the pin of the male buckle 7 can be placed in the sliding groove 15 to form a limit, preventing the pin of the male buckle 7 from coming out of the fixing hole of the female buckle 8. The size of the cavity on the fixed slide plate 9 through which the male buckle 7 and the female buckle 8 pass is larger than the size of the male buckle 7 and the female buckle 8 stacked, so that the fixed slide plate 9 can be placed at the connection of the male buckle 7 and the female buckle 8 stacked.

[0028] The cable retainer 12 is provided with several through holes 16 to reduce the overall weight.

[0029] When using this folding cable winch, one end of the cable is fixed on the drum 13, and then the crank 3 is turned to drive the drive shaft 2 to rotate. The drive shaft 2 drives the cable winding assembly to rotate, thereby realizing the winding or unwinding of the cable.
