Description

Technical Field

[0001] The utility model belongs to the technical field of tension cable tension layer locking, and relates to a tension cable tension layer locking tool. Background Art

[0002] In underground coal mine production, belt conveyors are responsible for the main work of coal transportation. In accordance with the relevant requirements of coal mine safety production, belt conveyors must be equipped with corresponding protection devices to ensure production safety. The belt protection device consists of a host computer, a sensor, an emergency stop switch, etc. The emergency stop switch is installed along the belt line, and the installation interval shall not be greater than 100 meters.

[0003] The emergency stop switch is equipped with an emergency stop button. The emergency stop switches along the line are connected in series through multi-core cables. The emergency stop switch and the multi-core cable are electrically connected in a quick plug-in form. A linkage mechanism is provided inside the emergency stop switch. When the quick-connect plug is pulled outward, the emergency stop button will be pressed in linkage. During the operation of the belt conveyor, when the inspection worker finds a fault along the belt, he can stop the conveyor quickly by pressing the nearest emergency stop switch along the line. When the inspection worker is far away from the emergency stop switch, he can pull the multi-core cable connected to the emergency stop switch to make the emergency stop button pressed in linkage to achieve a quick stop.

[0004] The emergency stop switch along the line is equipped with a detection and communication circuit, which is connected to the host computer through a multi-core cable. The host computer supplies power to the emergency stop switch along the line through the power line in the multi-core cable, and communicates data with the emergency stop switch through the signal line in the cable to obtain the working status of the emergency stop switch. Multi-core cables must have a wire pulling function while realizing electrical functions. In order to ensure that the internal wire core will not be stretched, deformed or broken when the cable is pulled to realize the wire pulling emergency stop function, a tensile layer composed of multiple tensile steel wires must be provided between the core layer and the outer sheath layer of the multi-core cable. The cable with a tensile function has quick cable plug connectors welded at both ends, and the tensile layer steel wire must be integrated and fixedly connected with the quick cable plug to increase the tensile strength of the cable.

[0005] The tension layer steel wire of the tension cable and the cable quick plug connector are generally hard-connected. That is, multiple strands of tension steel wire are placed outside the fixing groove of the quick plug, and the fastening copper clamp is placed outside the fixing groove, so that the tension steel wire is between the fixing groove and the copper clamp, and the copper clamp is pressed and fixed in the fixing groove of the quick plug through the locking tool, so that the tension steel wire and the quick plug are fastened as one.

[0006] The current locking tooling has the following main problems: the torque control is difficult, and multiple strands of tension steel wire are difficult to compress or easily broken; the copper clamp is easy to shift, so that it cannot be completely tightened in the fixing groove of the quick plug, which makes the outer circumference larger, making it difficult to insert the cable head sheath for subsequent processing; after the copper clamp is compressed, it deforms and sticks to the clamping tool and is difficult to separate. In view of the above problems, it is of great significance to design a cable tension layer locking tooling that can improve the locking effect of the tension steel wire and improve the convenience of operation. Summary of the invention

[0007] In view of this, the purpose of the utility model is to provide a tension layer locking tool for a tension cable that can solve the above-mentioned problem.

[0008] In order to achieve the above object, the utility model provides the following technical solutions:

[0009] A tension cable tension layer locking tooling, comprising a dynamic pressure sleeve, a static pressure sleeve and a power device applying a clamping force to the dynamic pressure sleeve, the dynamic pressure sleeve and the static pressure sleeve are respectively provided with a semicircular arc structure matching the copper clamp, the upper and lower ends of the semicircular arc structures of the dynamic pressure sleeve or the static pressure sleeve are respectively provided with vertical large clamping protrusions integrated therewith, and the upper and lower ends of the corresponding semicircular arc structure of the other compression sleeve are respectively provided with large clamping grooves matching the large clamping protrusions, the static pressure sleeve is vertically fixed to one end of a tooling base, the semicircular arc structure of the static pressure sleeve is arranged outward, the other end of the tooling base is fixed with a power device, the tooling base between the power device and the static pressure sleeve is provided with a dynamic pressure sleeve, the bottom end of the dynamic pressure sleeve is provided with a sliding block integrated therewith, and the corresponding tooling base is provided with a guide slideway corresponding thereto.

[0010] Furthermore, the groove width of the large pressing groove is greater than the width of the large pressing protrusion.

[0011] Furthermore, a vertical small clamping groove is provided in the middle of the large clamping protrusion, and a corresponding small clamping protrusion is provided in the middle of the large clamping groove so as to be integrated therewith.

[0012] Furthermore, the power device is a hydraulic pliers.

[0013] Furthermore, a knocking separation crown is provided on the top of the dynamic pressure sleeve and is integrated therewith for separating the dynamic pressure sleeve from the copper clamp.

[0014] Furthermore, the tooling base is fixed on the bottom plate.

[0015] The beneficial effects of the utility model are:

[0016] The utility model has a simple structure and is easy to operate, and can quickly fix the copper clamp in the fixing groove of the cable quick-connect plug;

[0017] The power device of the utility model adopts hydraulic pliers as the power source. The hydraulic pliers can be operated with one hand, have a simple structure and are easy to maintain; the handle has a small pressing torque, the piston ejection torque is large, and the force is applied evenly; the piston ejection speed and position are easy to control;

[0018] The utility model designs a guide slideway for the dynamic pressure sleeve. During the locking process of the copper clamp, the dynamic pressure sleeve can move along the guide slideway to maintain a fixed track under the push of the hydraulic jacking pipe, thereby ensuring that the copper clamp can be stressed positively and improving the crimping quality of the copper clamp.

[0019] The utility model designs a knocking separation crown for the dynamic pressure sleeve. After the crimping is completed, the dynamic pressure sleeve and the copper clamp that are squeezed and bonded together can be easily separated by lightly knocking the place with a hammer. The design of the knocking separation crown makes the separation work of the dynamic pressure sleeve and the copper clamp simple, changes the previous separation method that requires strong knocking of the dynamic pressure sleeve body, and reduces the cable quick-connect plug damage accidents caused by strong knocking to zero.

[0030] In the description of the present invention, it should be noted that, unless otherwise clearly specified and limited, the terms "installation", "connection" and "connection" should be understood in a broad sense, for example, it can be a fixed connection, a detachable connection, or an integral connection; it can be a mechanical connection or an electrical connection; it can be a direct connection, or it can be an indirect connection through an intermediate medium, or it can be the internal communication of two components. For ordinary technicians in this field, the specific meanings of the above terms in the present invention can be understood by specific circumstances.

[0031] The present invention will be described in detail below with reference to the accompanying drawings and in combination with embodiments.

[0032] As shown in the figure, a tension cable tension layer locking tool comprises a dynamic pressure sleeve 1, a static pressure sleeve 2 and a power device 3 for applying a pressing force to the dynamic pressure sleeve 1. The dynamic pressure sleeve 1 and the static pressure sleeve 2 are matched to lock the copper clamp 41 on the cable quick connector. The dynamic pressure sleeve 1 and the static pressure sleeve 2 are respectively provided with a semi-circular arc structure a matching the copper clamp 41. The upper and lower ends of one of the semi-circular arc structures a of the dynamic pressure sleeve 1 or the static pressure sleeve 2 are respectively provided with a vertical large pressing protrusion 11 integrated therewith, and the upper and lower ends of the semi-circular arc structure a of the corresponding other compression sleeve are respectively provided with a large pressing groove 21 matching the large pressing protrusion 11. Since the inner diameter of the copper clamp 41 is larger than the outer diameter of the groove on the cable quick connector, in order to facilitate the pressing of the copper clamp 41, the groove width of the large pressing groove 21 is greater than the width of the large pressing protrusion 11, so that the gap between the two is used to form the wrinkles of the copper clamp 41 after extrusion.

[0033] In order to facilitate the formation of wrinkles on the copper clamp 41, a vertical small pressing groove 111 is opened in the middle of the large pressing protrusion 11, and a corresponding small pressing protrusion 211 is arranged in the middle of the large pressing groove 21.

[0034] The static pressure sleeve 2 is vertically fixed to one end of the tooling base 5, and the semi-circular arc structure a of the static pressure sleeve 2 is arranged outward. A power device 3 is fixed to the other end of the tooling base 5. A dynamic pressure sleeve 1 is arranged on the tooling base 5 between the power device 3 and the static pressure sleeve 2, and the semi-circular arc structure a of the dynamic pressure sleeve 1 faces the semi-circular arc structure a of the static pressure sleeve 2. The bottom end of the dynamic pressure sleeve 1 is provided with a slider 13 integrated therewith, and the corresponding tooling base 5 is provided with a corresponding guide slideway. When the power device 3 pushes the dynamic pressure sleeve 1, the dynamic pressure sleeve 1 slides on the guide slideway and approaches the static pressure sleeve 2. During the locking process of the copper clamp 41, the dynamic pressure sleeve 1 can move along the guide slideway while maintaining a fixed trajectory under the push of the power device 3, thereby ensuring that the copper clamp 41 can be subjected to positive force and improving the crimping quality of the copper clamp 41.

[0035] The power device 3 can be a hydraulic pliers, a hydraulic cylinder, etc. The preferred power device 3 is a hydraulic pliers. The hydraulic pliers are fixed on the tooling base 5, and the piston push rod of the hydraulic pliers cooperates with the dynamic pressure sleeve 1. The hydraulic pliers are integrated hydraulic pliers. The working pressure of the hydraulic pliers is 8T, and the piston push rod stroke is 14mm. Compared with other electric or pneumatic tools, the advantages of using hydraulic pliers as a power source are: single-handed operation, simple structure, easy maintenance; small handle pressing torque, large piston ejection torque, uniform force; easy control of piston ejection speed and position.

[0036] Preferably, the top of the dynamic pressure sleeve 1 is provided with a knocking separation crown 12 integrated therewith. After the power device 3 compresses the dynamic pressure sleeve 1 and the static pressure sleeve 2, under the action of the pressing force, after the cable quick-connect plug 4 is removed, the dynamic pressure sleeve 1 will adhere to the copper clamp 41, so it is necessary to remove the dynamic pressure sleeve 1, and gently knock the knocking separation crown 12 to easily separate the dynamic pressure sleeve 1 and the copper clamp 41 that are squeezed and bonded together. The design of the knocking separation crown 12 makes the separation of the dynamic pressure sleeve 1 and the copper clamp 41 simple, changing the previous separation method that requires strong knocking of the dynamic pressure sleeve 1 body, and reducing the previous cable quick-connect plug 4 damage accidents caused by strong knocking to zero.

[0037] The tooling base 5 is fixed on the bottom plate 6 .

[0038] The working principle of this utility model:

[0039] Weld the core wire of the tension cable and the wire spring jack of the quick-connect plug firmly. Straighten the tension layer steel wire so that it is evenly distributed outside the quick connector fixing groove. Insert the copper clamp 41 into the quick connector fixing groove position so that the tension layer steel wire is clamped between the copper clamp 41 and the fixing groove. Place it between the static pressure sleeve 2 and the dynamic pressure sleeve 1 on the locking tooling.

[0040] Hold the cable and adjust the direction of the cable quick connector 4 so that the end face of the cable quick connector 4 is parallel to the end face of the compression sleeve; fine-tune the position of the copper clamp 41 by hand so that it is located directly above the fixed groove. Hold the cable and manually press the hydraulic pliers to slowly push out the piston push rod of the hydraulic pliers, and the dynamic pressure sleeve 1 corresponding to the piston push rod moves forward accordingly, gradually working with the static pressure sleeve 2 to act on the copper clamp 41, compressing and shrinking it, and finally the copper clamp 41 fastens the tensile layer steel wire to the fixed groove.

[0041] Unscrew the pressure relief screw of the hydraulic pliers, the piston push rod retreats, the dynamic pressure sleeve 1 is adhered to the copper clamp 41 due to compression and deformation, take out the crimped cable plug and the dynamic pressure sleeve 1 together, and use a hammer to knock the knocking crown on the dynamic pressure sleeve 1, and the dynamic pressure sleeve 1 can be easily separated from the shrunk copper clamp 41. At this point, the tension cable tension layer locking process is completed.

[0042] The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. Any modifications, equivalent substitutions, improvements, etc. made within the spirit and principles of the present invention should be included in the protection scope of the present invention.
