Detailed Implementation

[0012] To make the above-mentioned objectives, features and advantages of this utility model more apparent and understandable, the specific embodiments of this utility model will be described in detail below with reference to the accompanying drawings.

[0013] It should be noted that in the description of this utility model, "upper," "lower," "top," "bottom," and orientation or positional relationship are based on the appendix. Figure 1The orientations or positional relationships shown are for the convenience of describing this utility model and simplifying the description, and are not intended to indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limitations on this utility model.

[0014] In one embodiment, such as Figure 1 and Figure 2 As shown, the portable downhole cable clamping device of this embodiment includes: Base 100 is used to support cables and lugs. Specifically, base 100 is a rectangular corrosion-resistant plate.

[0015] A U-shaped bracket 200 is vertically mounted on the top of the base 100. The top of the U-shaped bracket 200 is fixedly connected to the base 100. An internal threaded hole is provided in the middle of the bottom of the U-shaped bracket, and the axis of the internal threaded hole is perpendicular to the base 100.

[0016] The crimping screw 300 is used to contact the wire lug and apply pressure to the wire lug. It is set perpendicular to the base 100 and threaded into the fixing nut. During the tightening process, the crimping screw 300 moves downward relative to the internal threaded hole, applying pressure to the wire lug on the base 100, so that the wire lug is tightly connected to the cable conductor to complete the crimping operation.

[0017] The base 100 is provided with a U-shaped groove 400 for limiting the cable and lug. Specifically, the U-shaped groove 400 is located directly below the internal threaded hole, and its length is less than the width of the base 100. During wire crimping, the cable and lug are placed in the U-shaped groove 400, and the end located in the middle of the base 100 can abut against the lug.

[0018] If you try to insert the loose conductors directly without any treatment, it will not only be difficult, but also may cause serious safety hazards such as loose connection, increased contact resistance, and local overheating because some conductor wires are bent outside the insertion tube.

[0019] To address the aforementioned problems, in this embodiment, a conductor combing assembly 110 is provided on the top of the base 100. The conductor combing assembly 110 includes a base 120 and a pressure plate 130 of the same shape and size. Figure 3As shown, the top of the base 120 has a first semi-frustum groove 140 and a second semi-frustum groove 150 extending through it, and the bottom of the pressure plate 130 also has a first semi-frustum groove 140 and a second semi-frustum groove 150 extending through it. The base 120 is fixedly connected to the base 100, and the pressure plate 130 is disposed on the top of the base 120. The first semi-frustum groove 140 of the base 120 and the pressure plate 130 combine to form a first conical hole 160, and the second semi-frustum groove 150 of the base 120 and the pressure plate 130 combine to form a second conical hole 170. The axes of the first conical hole 160 and the second conical hole 170 are both parallel to the center line of the U-shaped groove 400. The base 120 and the pressure plate 130 are equivalent to a set of molds to realize the upper and lower pressing of the cable conductor.

[0020] The top radius of the first conical hole 160 is smaller than the top radius of the second conical hole 170, and different conical holes are suitable for wires of different sizes.

[0021] The pressure plate 130 is hinged to the base 120 by at least one hinge 180. The two ends of the hinge 180 are fixedly connected to the base 120 and the side wall of the pressure plate 130 that is parallel to the center line of the U-shaped groove 400, respectively.

[0022] During operation, first lift the pressure plate 130, then place the scattered cable conductors into a semi-conical groove of the base 100 according to their size selection, and lower the pressure plate 130 so that the cable conductors pass through the conical hole formed by the semi-conical groove. During the passage, the messy conductor wires will be forcibly gathered and aligned.

[0023] The portable underground cable pressing device of this embodiment has a simple structure, is easy to hold and carry, and is very suitable for use in the confined spaces of underground mines. It requires no cumbersome preparation work and offers high cable pressing efficiency in mines. In one embodiment, a rotating handle 500 for rotating the crimping screw 300 is also provided. The rotating handle 500 includes a connecting rod 510 and a rotating rod 520. The connecting rod 510 is arranged parallel to the base 100 and fixedly connected to the end of the crimping screw 300 away from the base 100. The rotating rod 520 is arranged perpendicular to the base 100 and fixedly connected to the end of the connecting rod 510 away from the crimping screw 300. A handle 700 is provided on a horizontal side wall of the base 100 to facilitate the handling of the entire device.

[0024] Turning the handle 500 makes it easy to rotate the wire clamping screw, allowing workers to apply pressure to the wire lug more effectively.

[0025] The working process of the portable downhole cable crimping device in this embodiment is as follows: Place the cable lug to be crimped into the U-shaped groove 400 of the base 100; insert the cable conductor with the insulation removed into the insertion tube of the cable lug; the operator holds the device steady with one hand and rotates the handle 500 clockwise with the other hand to drive the crimping screw 300 to move downward and gradually contact and press the insertion tube of the cable lug, causing it to deform and thus tightly and firmly bond with the cable conductor; after the crimping operation is completed, rotate the handle 500 counterclockwise to make the crimping screw 300 rise and reset, and take out the crimped cable.

[0026] The above-described embodiments are merely illustrative of several implementations of this utility model, and while the descriptions are relatively specific and detailed, they should not be construed as limiting the scope of this utility model patent. It should be noted that those skilled in the art can make various modifications and improvements without departing from the concept of this utility model, and these all fall within the protection scope of this utility model. Therefore, the protection scope of this utility model should be determined by the appended claims.
