Description

Technical Field

[0001] The utility model belongs to the technical field of power line construction equipment, and specifically relates to a multifunctional wire hydraulic crimping device. Background Art

[0002] The aforementioned wire hydraulic crimping device is also commonly referred to as a wire hydraulic crimping machine, which is composed of a power source and a hydraulic clamp. The function of the power source is to ensure the operation of the hydraulic clamp, and the hydraulic clamp plays the role of reliably crimping the connecting sleeve between two adjacent wire ends to connect the wires. Because as is known in the industry, during the construction of overhead lines (overhead open wires), it is necessary to connect the end of the previous wire (usually steel-core aluminum stranded wire, the same below) that is about to be exhausted and withdrawn from the wire coil with the starting end of the wire withdrawn from another (i.e., the next) wire coil, and the connection method is usually achieved by using both steel core sleeve and aluminum sleeve. Specifically, first remove the aluminum stranded wire of the length required by the specification from the end of the previous wire and the starting end of the next wire, but retain the steel core wire (i.e., steel stranded wire, the same below), and then crimp the steel sleeve outside the steel core wire, and then crimp the aluminum sleeve between the beginning and end of the aluminum stranded wire and press the middle of the aluminum sleeve with the steel sleeve at the same time, so as to ensure the connection reliability at the joint. There is another situation: although overhead wires have the advantages of low cost, strong mobility and easy maintenance, they are easily affected by natural factors such as strong winds, lightning strikes, ice and snow, hail, freezing, dirt and the like, and line breakage is inevitable, so they need to be repaired in time. During the repair process, it is also necessary to use the aforementioned wire hydraulic crimping device and carry out construction in the same manner as described above.

[0003] Since the wire hydraulic crimping machine in the prior art is only composed of a power source and a hydraulic pliers, more specifically, the power source only provides working power to the hydraulic pliers as an actuator, so that the hydraulic pliers can crimp the aforementioned steel casing and aluminum casing. Typical examples of this structure include the "threaded steel sleeve cold extruder" recommended by CN2263558Y, the "hydraulic wire crimping pliers with overload protection function" introduced in CN100421315C, the "hydraulic wire crimping machine" disclosed in CN2742641Y, and the "hydraulic oil circulation filter mechanism of the wire hydraulic crimping machine" disclosed in CN102011768A, etc.

[0004] However, the removal of the aluminum strands at the ends of the conductors and / or the cutting of the aluminum strands and steel core wires as needed (for example, the redundant conductors need to be cut after the entire line is completed) require the use of separately equipped tools such as hydraulic shears. Since there is no structural correlation between tools such as hydraulic shears and the conductor hydraulic crimping machine, on the one hand, there are many types of power construction tools and they are scattered, which brings certain troubles to daily maintenance work, such as easy loss or forgetting to bring them due to distraction; on the other hand, due to the structural design of the hydraulic shears themselves, it is difficult to reliably control the conductors during the cutting process, resulting in irregular incisions; on the other hand, the operation is relatively cumbersome. Based on the above factors, it is of positive significance to explore the design of the conductor hydraulic crimping machine, which only has the single function of crimping the casing in the existing technology, and can not only cut the aluminum strands of the conductor together with the steel strands as needed, but also cut only the aluminum strands outside the steel core wire as needed. The technical solution to be introduced below is produced in this context. Utility Model Content

[0056] Please combine Figures 1 to 5When it is necessary to cut off the damaged aluminum strands of the overhead wire without damaging the central steel core wire, i.e., the steel strands, that is, to implement a half-cut operation of only cutting off the aluminum strands, the second operating handle 156 mentioned above is activated, and the construction personnel pull the second operating handle 156 to the left, and the half-cut hydraulic cylinder inlet and return pipe matching interface 153 discharges oil, and the hydraulic oil passes through the half-cut hydraulic cylinder inlet and return pipe 31111, the half-cut hydraulic cylinder inlet and return pipe interface 3111, the half-cut hydraulic cylinder inlet and return hole 3112 and the bottom of the half-cut hydraulic cylinder cylinder piston 3151 in turn, so that the half-cut hydraulic cylinder cylinder piston 3151 moves upward, and the half-cut hydraulic cylinder cylinder 315 overcomes the reaction force (reaction force) of the cylinder column reset spring 313 and moves upward, driving the half-cut moving knife 332 upward, so that the half-cut moving knife 332 enters the cutting state of the aluminum strands under the coordinated action of the half-cut static knife 331. After cutting, when the operator moves the second operating handle 156 to the middle gear (i.e. neutral), the half-cut hydraulic cylinder column 315 is moved downward (reset) under the restoring force of the cylinder column reset spring 313. At this time, the hydraulic oil below the half-cut hydraulic cylinder column piston 3151 flows in the reverse process through the half-cut hydraulic cylinder oil inlet and return hole 3112, the half-cut hydraulic cylinder oil inlet and return pipe interface 3111, the half-cut hydraulic cylinder oil inlet and return pipeline 31111 and the half-cut hydraulic cylinder oil inlet and return pipe matching interface 153 until it returns to the hydraulic oil tank 13.

[0058] Please combine Figures 1 to 2 as well as Figures 6 to 8When it is necessary to implement circumferential cutting of the overhead wire, that is, to cut off all the wires, that is, to cut off the aluminum stranded wire and the steel core wire together, when the power source 1 is in working condition, the construction personnel pull the second operating handle 156 to the right, and the oil inlet and return pipe fitting interface 154 of the circumferential cutting hydraulic oil cylinder discharges oil, and the hydraulic oil passes through the circumferential cutting hydraulic oil cylinder oil inlet and return pipe 41111, the circumferential cutting hydraulic oil cylinder oil inlet and return pipe interface 4111, the circumferential cutting hydraulic oil cylinder oil inlet and return hole 4112 and the bottom of the circumferential cutting hydraulic oil cylinder cylinder piston 4151 in sequence, so that the circumferential cutting hydraulic oil cylinder cylinder piston 4151 moves upward, and the circumferential cutting hydraulic oil cylinder cylinder column 415 overcomes the reaction force (reaction force) of the cylinder column return spring 413 and moves upward, driving the circumferential cutting movable knife 432 to move upward, so that the circumferential cutting movable knife 432 enters the wire cutting (also called "cutting") state under the coordinated action of the circumferential cutting static knife 431. After cutting off, when the operator moves the second operating handle 156 to the middle gear (i.e. neutral), the circular cutting hydraulic cylinder column 415 is moved downward (reset) under the restoring force of the aforementioned cylinder column reset spring 413. At this time, the hydraulic oil located below the aforementioned circular cutting hydraulic cylinder column piston 4151 flows in the reverse process through the circular cutting hydraulic cylinder oil inlet and return hole 4112, the circular cutting hydraulic cylinder oil inlet and return pipe interface 4111, the circular cutting hydraulic cylinder oil inlet and return pipeline 41111 and the circular cutting hydraulic cylinder oil inlet and return pipe matching interface 154 until it returns to the hydraulic oil tank 13.

[0059] Before implementing the aforementioned cutting of the wire, first remove the aforementioned left pin shaft 427 and / or right pin shaft 428, introduce (pull) the wire into between the circumferential cutting static knife 431 and the circumferential cutting movable knife 432, and preferably use a limiting component such as a clamp to limit the wire on both sides to avoid the aluminum strands of the wire from spreading out at the incision site, and then return the aforementioned left pin shaft 427 and / or right pin shaft 428.
