Description

Technical Field

[0001] The invention belongs to the technical field of mine wire rope insertion, and in particular relates to a mine wire rope hole expander. Background Art

[0002] The wire rope hole expander is a tool for inserting hook heads of underground wire ropes. The existing wire rope hole expanders have a simple structure and only use a sharp solid pin as a hole expander to expand the hole. In addition, for safety reasons, underground wire ropes are often made of thicker wire ropes woven from multiple strands of thinner wire ropes, which are relatively dense. Usually, one end of the wire rope is passed through the hook head at the rear end of the winch, and then the wire rope is folded back, and then the sharp solid pin is inserted into the gap on the wire rope, and it is swung back and forth with force to expand the insertion of the wire rope. The gap is enlarged, and the folded back wire rope end is inserted into the enlarged gap and tightened, and the hole is enlarged at multiple positions on the wire rope and the wire rope end is wound in the enlarged gap to prevent the wire rope from being separated from the hook head, so as to ensure the tightness of the connection between the wire rope and the hook head; hole enlargement is difficult, and two workers are often required to carry out hole enlargement, which makes hole enlargement and rope insertion on the wire rope time-consuming and labor-intensive, and rope insertion is relatively frequent underground, so a hole enlarger that can quickly enlarge the hole and save time and labor is needed to solve the above problems. Summary of the invention

[0003] The purpose of the present invention is to provide a mine wire rope hole expander to solve the problems of difficulty, time and labor in hole insertion and hole expansion during the process of wire rope insertion in the mine.

[0004] The present invention adopts the following technical scheme: a mine wire rope hole expander, comprising: a horizontally arranged sliding plate, one side of the sliding plate is connected to a lifting mechanism, and the other side is connected to a vertically arranged rope inserting cone; the rope inserting cone has a conical tip, and two movable plates are symmetrically arranged on both sides of the rope inserting cone near the tip, and the inner sides of the two movable plates are connected to a hole-supporting mechanism; the rope inserting cone is used to pierce the wire rope to form a hole under the lifting action of the lifting mechanism;

[0005] The cam is an angular movement, a dovetailed shape, and a bottom end of the dovetailed shape is attached to the cam, the dovetailed shape being attached to a camshaft and being rotatable therein.

[0006] The threaded rod is used to move downward and drive the slider and the two pressure rods to move downward in turn, so that the X-shaped hinge assembly is compressed and the mounting block and the movable plate are pushed to both sides to achieve the expansion of the socket.

[0007] Furthermore, a fixing plate is provided below the tip of the rope insertion cone, and a puncture hole coaxial with the rope insertion cone is provided on the fixing plate. The puncture hole is a through hole or a blind hole. The fixing plate is used for placing the wire rope to be punctured; the puncture hole is used for providing downward space for the rope insertion cone during puncture.

[0008] Furthermore, limit rods are horizontally arranged on the upper ends of the two movable plates, and the limit rods are used to fix the position of the steel wire rope after the rope insertion cone pierces the steel wire rope.

[0009] Furthermore, the upper end of the threaded rod extends out of the rope inserting cone and is provided with a turntable.

[0010] The beneficial effects of the present invention are as follows: driven by the lifting action of the lifting mechanism, the wire rope is pierced through the rope cone to form a hole, so that the wire rope is stuck at the lower end of the limit rod and is located on the outside of the movable plate, which is convenient for the hole-supporting mechanism to expand the hole; the slider moves downward and drives the X-shaped hinge assembly to be compressed through the two pressure rods, so that the distance between the two ends of the X-shaped hinge assembly and the hinge point becomes larger, thereby driving the two movable plates to move outward through the two mounting blocks to expand the hole of the wire rope, so as to facilitate manual rope insertion; only one staff member is needed to complete the rope insertion work, the hole can be inserted and expanded quickly, and the labor intensity of the staff is reduced, which can conveniently solve the problems of difficult, time-consuming and labor-intensive rope insertion in the process of rope insertion in mines, and the operation is simple and suitable for popularization.

[0020] The hole-supporting mechanism 5 includes a threaded rod 502 vertically penetrating the rope-inserting cone 8, and a slider 506 is connected to the lower end of the threaded rod 502. The threaded rod 502 is rotated so that the threaded rod 502 moves toward the inside of the rope-inserting cone 8 while rotating, driving the slider 506 to move downward. A mounting plate 504 is also fixedly arranged in the rope-inserting cone 8, and a slide groove is vertically opened on the mounting plate 504, and the slide groove is used for the slider 506 to move up and down therein; two pressure rods 507 and an X-shaped hinge assembly 501 are arranged in sequence in the rope-inserting cone 8 and below the slider 506; the X-shaped hinge assembly 501 includes two cross-hinged mounting plates 504. Rod, the two pressure rods 507 are inverted V-shaped, and have two upper and lower endpoints on the left and right sides respectively, and the hinge point B and the hinge point D are arranged in another connecting groove 509; one end of the two pressure rods 507 are hinged to the slider 506, and the other ends are respectively hinged to the two rods, and are close to the two endpoints located above; the left and right sides of the X-shaped hinge assembly 501 are respectively provided with mounting blocks 508, and the two mounting blocks 508 are respectively connected to the two movable plates 7, and the two mounting blocks 508 are vertically provided with connecting grooves 509, and each connecting groove 509 is used for the two endpoints on the same side of the X-shaped hinge assembly 501 to move up and down therein.

[0021] like Figure 4 , is a schematic diagram of the structure of the hole-supporting mechanism 5 when supporting a hole. At this time, the hole-supporting mechanism 5 drives the two movable plates 7 to move outward to a limit distance.

[0022] like Figure 5 , is a schematic diagram of the structure of the hole-supporting mechanism 5 when it is contracted, and the left and right sides thereof respectively have two upper and lower endpoints, which are hinge points A, hinge points B, hinge points C and hinge points D, respectively. The hinge points A and C are arranged in one of the connection grooves 509, and the hinge points B and D are arranged in the other connection groove 509;

[0023] The threaded rod 502 is used to move downward and in turn drive the slider 506 and the two pressure rods 507 to move downward, so that the X-shaped hinge assembly 501 is compressed, and pushes the mounting block 508 and the movable plate 7 to both sides to achieve the expansion of the hole. The slider 506 moves downward to drive the X-shaped hinge assembly 501 to be compressed through the two pressure rods 507, so that the distance between the two ends of the X-shaped hinge assembly 501 and the hinge point becomes larger, thereby driving the two movable plates 7 to move outward through the two mounting blocks 508 to expand the hole of the wire rope.

[0024] A fixing plate 1 is provided below the tip of the rope inserting cone 8, and a puncture hole 6 coaxial with the rope inserting cone 8 is provided on the fixing plate 1. The puncture hole 6 is a through hole or a blind hole. The fixing plate 1 is used for placing the steel wire rope to be punctured; the puncture hole 6 is used for providing a downward space for the rope inserting cone 8 during puncture, so that the puncture of the steel wire rope is more convenient.

[0025] A limit rod 503 is horizontally arranged at the upper end of the two movable plates 7 to fix the position of the wire rope after the rope insertion cone 8 pierces the wire rope. The limit rod 503 is used to fix the position of the wire rope so that the wire rope sleeved on the rope insertion cone 8 is outside the two movable plates 7, which is convenient for supporting the wire rope.

[0026] The upper end of the threaded rod 502 extends out of the rope inserting cone 8 and is provided with a turntable 505 , so as to achieve a labor-saving effect by increasing the torque of the threaded rod 502 .

[0027] The working principle of the present invention is as follows: when connecting the pull ring at the rear end of the winch, firstly, the fixing plate 1 is fixedly installed on the ground by the fixing bolts 8, the steel wire rope is placed on the fixing plate 1 and is above the puncture hole 6, and then one end of the steel wire rope is passed through the pull ring and folded back, and the staff fixes the steel wire rope by using hands or feet;

[0028] The lifting mechanism 3 is pressed downward, and the lifting mechanism 3 drives the rope insertion cone 8 to descend. When the conical tip of the rope insertion cone 8 is inserted into the gap on the wire rope, the lifting mechanism 3 is continuously pressed downward until the wire rope is at the lower end of the limit rod 503, and the wire rope is sleeved between the two movable plates 7. The turntable 505 is rotated, and the turntable 505 rotates and is threadedly connected with the top wall of the rope insertion cone 8, so that the threaded rod 502 rotates and moves downward, driving the slider 506 to move downward. The slider 506 moves downward and drives the X-shaped hinge assembly 501 to be compressed through the two pressure rods 507, so that The distance between the two ends of the X-shaped hinge assembly 501 and the hinge point becomes larger, so that the two movable plates 7 are driven to move outward through the two mounting blocks 508 to expand the sockets on the wire rope, and then the turntable 505 is rotated in the opposite direction to make the two movable plates 7 slide inward and disengage from the wire rope. Then the lifting mechanism 3 is used, and the staff manually passes one end of the wire rope passing through the pull ring through the expanded socket for weaving. Then the above operation is repeated to expand multiple sockets on the wire rope, and all the ends of the wire rope passing through the pull ring are inserted into and woven into the expanded sockets.

[0029] Driven by the lifting action of the lifting mechanism of the present invention, the wire rope is pierced through the rope cone to form a hole, so that the wire rope is stuck at the lower end of the limit rod and is located on the outside of the movable plate, which is convenient for the hole-supporting mechanism to expand the hole; the slider 506 moves downward and drives the X-shaped hinge assembly 501 to be compressed through the two pressure rods 507, so that the distance between the two ends of the X-shaped hinge assembly 501 and the hinge point becomes larger, thereby driving the two movable plates 7 to move outward through the two mounting blocks 508 to expand the hole of the wire rope, so as to facilitate manual rope insertion; the puncture hole 6 is used to provide downward space for the rope insertion cone 8 during puncture; the limit rod 503 is used to fix the position of the wire rope, so that the wire rope sleeved on the rope insertion cone 8 is outside the two movable plates 7, which is convenient for supporting the wire rope; it can conveniently solve the problems of difficulty, time and labor in rope insertion in the mine, simple operation, and suitable for promotion.
