Description

Technical Field

[0001] The invention relates to the technical field of cable crimping, in particular to a cable crimping pliers for electric power engineering. Background Art

[0002] Cable crimping pliers are often used for cable crimping during emergency repairs and daily operations of power facility operation and maintenance. Existing crimping pliers need to be replaced with different crimping dies according to the diameter of the crimped cable during use. Faced with the complex and changeable on-site environment, replacing the crimping die greatly increases the on-site construction risk and reduces the implementation efficiency. It is impossible to meet the on-site requirements of using a pair of pliers to crimp multiple conventional wire diameters. When crimping cables with unconventional wire diameters, the cables are easily broken or seriously damaged during the crimping process. Therefore, it is necessary to design a crimping pliers to meet the needs of on-site construction.

[0003] At present, the existing cable crimping pliers for power engineering (patent publication number: CN112467493B) discloses a cable crimping pliers, including a main body, an opening is provided at the front end of the main body, a second clamp body is slidably connected to the inner side of the opening, a first clamp body is provided in the main body, one side of the first clamp body is connected to a hydraulic telescopic rod, and also includes a distance measuring device provided on the main body, a limiting device provided on the main body, a first guide box provided in the main body and a second guide box provided at the opening, one end of the first clamp body is fixed to the first guide box, and the other end of the first clamp body is slidably connected to the first guide box, one end of the second clamp body is fixed to the second guide box, and the other end of the second clamp body is slidably connected to the second guide box, one end of the first clamp body squeezes the other end of the second clamp body, and one end of the second clamp body squeezes the other end of the first clamp body; the distance measuring device and the limiting device are used in conjunction with each other.

[0004] However, during the implementation of the above technical solution, at least the following technical problems were found:

[0005] 1. Poor crimping effect and easy damage to the internal copper wire: When using existing cable crimping pliers, the two main pliers squeeze and deform the cable connector, so that the cable connector and the copper wire of the cable are crimped together. However, since the existing crimping head adopts the form of "surface" crimping (limited force range), only the original inner diameter of the cable connector is changed (that is, the inner diameter of the cable connector is reduced by squeezing, so that the connector clamps the copper wire, thereby increasing the friction between the two, and the copper wire is difficult to be pulled out of the cable connector). As a result, the connector and the copper wire form an interference fit. The bearing capacity of the interference fit is related to the pressing force, which makes it important to control the pressing force. If you are not careful, it will cause breakage or loose pressing. Secondly, in order to ensure the stability of the connection, the copper wire needs to be deformed to a certain extent, which leads to damage to the copper wire.

[0006] 2. Poor positioning effect: When using existing cable crimping pliers, manual control is mainly used to determine the start and stop of the device. However, since cables of different sizes require different crimping strengths, adaptive adjustments are required, resulting in the inability to use the same standard for crimping. Moreover, since emergency stop is not possible during crimping, it is easy to cause the cable or connector to be broken. Secondly, although there is also a distance meter to measure the distance to determine the crimping depth and control the start and stop of the device, multiple adjustments are required when setting the crimping depth. This is because when the pliers are crimped, the crimping point is covered by the structure of the device, so the crimping depth cannot be observed intuitively. For this reason, we propose a cable crimping pliers for power engineering. Summary of the Invention

[0007] (1) Technical problems solved

[0008] In view of the deficiencies of the existing technology, the present invention provides a cable crimping pliers for electric power engineering, which solves the technical problems of the existing cable crimping pliers in use, such as poor crimping effect, easy damage to internal copper wires and poor positioning effect.

[0009] (2) Technical solution

[0010] To achieve the above objectives, the present invention is implemented through the following technical solutions:

[0011] A cable crimping pliers for electric power engineering, comprising a main body for mounting a pliers body, and two pliers bodies mounted inside the main body, one of which is movable while the other is immovable. The movable pliers body is moved toward the other pliers body by a hydraulic telescopic rod, thereby compressing the joint between the two pliers bodies.

[0012] The main body has a first clamp body movably mounted therein and sliding inside the main body;

[0013] A second caliper body is mounted on the end of the main body and corresponds to the first caliper body in front and back; and

[0014] The caliper body components are respectively mounted on opposite sides of the first caliper body and the second caliper body, and the caliper body components inside the first caliper body and the caliper body components inside the second caliper body are staggered with each other so that when the two calipers are attached to each other, the caliper body components inside them will not collide;

[0015] The clamp assembly includes two L-shaped supports, which correspond to each other up and down. A crimping rope is connected between the ends of the two supports. When crimping, the crimping rope is wrapped around the outside of the joint.

[0016] A hydraulic telescopic rod is connected between the first clamp body and the main body, and the hydraulic telescopic rod is used to drive the first clamp body to move toward the second clamp body, and does not provide tension for the crimping rope, so that the crimping rope tightens the joint and squeezes and deforms the joint.

[0017] Preferably, there are three sets of pliers body components, two sets are installed in the first pliers body and one set is installed in the second pliers body. Therefore, when crimping, indentations can be made on both sides of the joint, and the positions of the indentations are staggered. Thus, when crimping, the cable inside the joint can be crimped into an "S" shape, thereby improving the fitting strength between the cable and the joint.

[0018] Among them, when the first pliers body and the second pliers body are fitted together, the pliers body component inside the second pliers body is located between the two pliers body components inside the first pliers body, so that the outer wall of the joint is deformed in different directions simultaneously, forming an "S" shape and improving the fitting property between the cable and the joint.

[0019] Preferably, openings are provided inside both the first pliers body and the second pliers body, and the two openings are arranged oppositely. Covers are installed on the side walls of the first pliers body and the side walls of the second pliers body.

[0020] Among them, the pliers body component is installed in the opening, which is convenient for providing enough space for the joint.

[0021] Preferably, the body is in a "C" shape, and limiting connecting rods are connected to both ends of the body.

[0022] Among them, sockets are provided at both ends of the second pliers body, and the second pliers body is connected to the limiting connecting rod through the sockets, thereby fixing the second pliers body to one end of the body and corresponding to the first pliers body.

[0023] Preferably, a rotating shaft is installed at the bending part of the support member, and the rotating shaft is movably connected to the inner wall of the cover, so that the support member can rotate when受力.

[0024] Among them, a traction spring is connected between the two crimping ropes corresponding up and down, and the traction spring and the crimping rope are respectively located at both ends of the support member. The traction spring is always in a contracted state and can pull the support member when the support member is not受力, so that the support member returns to its original state, which is convenient for the next use.

[0025] Preferably, the support member includes a fixed rod and a traction rod connected end to end, and the included angle between the fixed rod and the traction rod is less than 180°.

[0026] Among them, when the traction rod is in contact with the inner wall of the opening, the two support members corresponding up and down are in contact with each other, so that the crimping rope is wound around the outside of the joint, thereby changing the shape of the joint and reducing the inner diameter of the joint.

[0027] Preferably, a distance measuring component is installed at the top of the body, and the distance measuring component is used to detect the moving distance of the first pliers body, so as to avoid the joint being broken or damaged during crimping.

[0028] The distance measuring assembly includes a scale piece mounted on the top of the body, and a slide groove is provided on the top of the scale piece. The extension direction of the slide groove is consistent with the movement direction of the first clamp body, and scales are provided on both sides of the slide groove to display the distance moved by the first clamp body, that is, the crimping distance;

[0029] A blocking piece is installed on the top of the first clamp body, and the blocking piece is inserted into the sliding groove and can move synchronously with the first clamp body, thereby displaying the moving distance of the first clamp body.

[0030] Preferably, conductive rods are movably mounted on the inner walls of both sides of the chute, and insulating sheets are connected to the two conductive rods. A power supply is installed inside the body to supply power to the electrical appliances.

[0031] The distance between the two conductive rods is equal to the width of the blocking piece, so that when the blocking piece slides, the two conductive rods can be connected;

[0032] A collar is installed on the outside of each of the two conductive rods, and one of the collars, the power supply, the hydraulic telescopic rod and the other collar are connected in series through wires. Therefore, when the baffle is in contact with the two conductive rods, the battery can keep powering the hydraulic telescopic rod. When the baffle is not in contact with the conductive rods, a short circuit is formed between the conductive rods, and the hydraulic telescopic rod is in a power-off state and no longer extends, thereby controlling the depth of the crimping.

[0033] Preferably, one end of the conductive rod is connected to the insulating sheet, and the other end passes through the scale sheet and corresponds to the slot provided inside the body. Therefore, when the insulating sheet is slid, the conductive rod can be driven to move synchronously, thereby adjusting the position of the conductive rod (i.e., adjusting the crimping depth). When the blocking piece slides out of the conductive rod, the power can be cut off.

[0034] The collar is connected to the portion of the conductive rod that passes through the scale sheet, thereby transmitting the positive and negative poles of the power supply to the two conductive rods to form a switch.

[0035] Preferably, a sleeve is installed at the front end of the body, and a rangefinder is sleeved on the outside of the sleeve;

[0036] The detection end of the rangefinder corresponds to the baffle on the top of the first caliper body, so when the baffle moves, the rangefinder can detect the moving distance of the baffle, which is convenient for detecting whether it is pressed to the specified depth.

[0037] (3) Beneficial effects

[0038] 1. Since a hydraulic telescopic rod is used to drive the crimping rope to crimp the connector, the technical problem of poor crimping effect and easy damage to the internal copper wire in the existing cable crimping pliers is effectively solved. The surrounding crimping is realized, so that the force during crimping is uniform. At the same time, the cable can be crimped into an "S" shape, thereby improving the connection strength between the cable and the connector. Secondly, it is convenient to observe the crimping condition.

[0039] 2. Since a sliding conductive rod is used to adjust the crimping depth, the technical problem of poor positioning effect of existing cable crimping pliers during use is effectively solved, thereby achieving rapid adjustment and at the same time being able to perform emergency power off of the device to ensure the safety of crimping.

[0052] The embodiment of the present application provides a cable crimping pliers for electric power engineering, which effectively solves the technical problems of existing cable crimping pliers in terms of poor crimping effect, easy damage to internal copper wires and poor positioning effect when in use. When the cable crimping pliers for electric power engineering are used, a hydraulic telescopic rod is used to drive the crimping rope to crimp the joint, thereby realizing surround-type crimping, so that the force during crimping is uniform, and the cable can be crimped into an "S" shape, thereby improving the connection strength between the cable and the joint. Secondly, it is convenient to observe the crimping situation; a sliding conductive rod is used to adjust the crimping depth, thereby realizing quick adjustment, and the device can also be powered off in an emergency to ensure the safety of the crimping.

[0053] Example 1

[0054] The technical solution in the embodiment of the present application is to effectively solve the technical problems that the existing cable crimping pliers have poor crimping effect and are easy to damage the internal copper wire when in use. The overall idea is as follows:

[0055] In response to the problems existing in the prior art, the present invention provides a cable crimping pliers for electric power engineering, including a monitoring device. The cable crimping pliers include a main body 1 for mounting a pliers body, and two pliers bodies are mounted inside the main body 1, one of which is movable and the other is immovable. The movable pliers body is moved toward the other pliers body by a hydraulic telescopic rod 8, thereby squeezing a joint between the two pliers bodies.

[0056] The main body 1 has a first clamp body 2 movably mounted therein, which slides inside the main body 1;

[0057] The second caliper body 3 is mounted on the end of the main body 1 and corresponds to the first caliper body 2 in front and back; and

[0058] The caliper body components are respectively installed on the opposite sides of the first caliper body 2 and the second caliper body 3, and the caliper body components inside the first caliper body 2 and the caliper body components inside the second caliper body 3 are staggered with each other so that when the two calipers are attached to each other, the caliper body components inside them will not collide;

[0059] Among them, the pliers body assembly includes two "L"-shaped support members 21, and the two support members 21 correspond up and down. A crimping rope 22 is connected between the ends of the two support members 21. During crimping, the crimping rope 22 is wound around the outside of the joint.

[0060] A hydraulic telescopic rod 8 is connected between the first pliers body 2 and the body 1, and the hydraulic telescopic rod 8 is used to drive the first pliers body 2 to move towards the second pliers body 3, and provides a pulling force for the crimping rope 22, so that the crimping rope 22 tightens the joint and squeezes the joint into deformation.

[0061] In some examples, there are three groups of pliers body assemblies. Two groups are installed in the first pliers body 2 and one group is installed in the second pliers body 3. Therefore, during crimping, indentations can be made on both sides of the joint, and the positions of the indentations are staggered. Therefore, during crimping, the cable inside the joint can be crimped into an "S" shape, thereby improving the fitting strength between the cable and the joint.

[0062] Among them, when the first pliers body 2 and the second pliers body 3 are fitted, the pliers body assembly inside the second pliers body 3 is located between the two groups of pliers body assemblies inside the first pliers body 2, so that the outer wall of the joint is deformed in different directions at the same time, forming an "S" shape and improving the fitting between the cable and the joint.

[0063] In some examples, openings are provided inside both the first pliers body 2 and the second pliers body 3, and the two openings are arranged opposite to each other. Covers 25 are installed on the side walls of the first pliers body 2 and the side walls of the second pliers body 3.

[0064] Among them, the pliers body assembly is installed in the openings, which is convenient for providing enough space for the joint.

[0065] In some examples, the body 1 is in a "C" shape, and limiting connecting rods 7 are connected to both ends of the body 1.

[0066] Among them, sockets are provided at both ends of the second pliers body 3, and the second pliers body 3 is connected to the limiting connecting rods 7 through the sockets, thereby fixing the second pliers body 3 to one end of the body 1 and corresponding to the first pliers body 2.

[0067] In the specific implementation process: the joint is placed in the gap between the two pliers bodies, and the crimping ropes 22 are respectively located on both sides of the joint, as Figure 6As shown, the hydraulic telescopic rod 8 is then controlled to extend, pushing the first clamp body 2 toward the second clamp body 3. At this time, the crimping ropes 22 inside the two clamp bodies are in contact with the outside of the joint, and under the action of the hydraulic telescopic rod 8, the joint is squeezed, thereby deforming the joint. Since the crimping ropes 22 inside the two clamp bodies are intertwined with each other, they can be crimped into intertwined indentations on the outside of the joint during crimping, so that the joint and the cable inside it are crimped and deformed to form an "S" shape, thereby avoiding the force direction of the cable being consistent with the extension direction of the cable when the cable is subjected to force, thereby improving the stability of the connection between the joint and the cable; at the same time, joints of different sizes and shapes can be uniformly crimped, thereby improving the applicability of the device.

[0068] Example 2

[0069] Based on Example 1, the present embodiment aims to improve the fit between the crimping rope 22 and the joint and ensure uniform force. The overall idea is as follows:

[0070] A rotating shaft 24 is installed at the bend of the support member 21, and the rotating shaft 24 is movably connected to the inner wall of the cover plate 25, so that the support member 21 can rotate when subjected to force;

[0071] Among them, a traction spring 23 is connected between the two corresponding upper and lower support members 21, and the traction spring 23 and the crimping rope 22 are respectively located at the two ends of the support member 21. The traction spring 23 is always in a contracted state and can pull the support member 21 when the support member 21 is not under force, so that the support member 21 returns to its original state, which is convenient for next use.

[0072] In some examples, the support member 21 includes a fixed rod 211 and a traction rod 212 connected end to end, and the angle between the fixed rod 211 and the traction rod 212 is less than 180°;

[0073] When the traction rod 212 fits against the inner wall of the opening, the two upper and lower fixing rods 211 fit against each other, so that the crimping rope 22 is wrapped around the outside of the joint, thereby changing the shape of the joint and reducing the inner diameter of the joint.

[0074] In the specific implementation process, during crimping, the crimping rope 22 is subjected to the reaction force of the joint, causing the two support members 21 to shrink toward the joint direction. Figure 7 As shown, at this time, the crimping rope 22 is wrapped around the outside of the joint. Then, as the hydraulic telescopic rod 8 is extended, the crimping rope 22 cannot move, and thus shrinks, and an annular indentation is also formed on the outside of the joint, causing the joint to deform inward, fit with the cable inside, and deform synchronously to form an "S" shape.

[0075] After the crimping is completed, the support member 21 is no longer subjected to stress, and the traction spring 23 pulls the support member 21 so that the support member 21 returns to its original state, making it convenient for next use.

[0076] Example 3

[0077] Based on Example 1, the embodiment of the present application effectively solves the technical problem of poor positioning effect of existing cable crimping pliers during use. The overall idea is as follows:

[0078] A distance measuring component 5 is installed on the top of the main body 1, and the distance measuring component 5 is used to detect the moving distance of the first clamp body 2 to prevent the joint from being broken or damaged during crimping;

[0079] The distance measuring assembly 5 includes a scale piece 51 mounted on the top of the body 1, and a slide groove is provided on the top of the scale piece 51. The extension direction of the slide groove is consistent with the movement direction of the first clamp body 2, and scales are provided on both sides of the slide groove to display the distance moved by the first clamp body 2, that is, the crimping distance.

[0080] A blocking piece 52 is installed on the top of the first clamp body 2 , and the blocking piece 52 is inserted into the slide groove and can move synchronously with the first clamp body 2 , thereby displaying the moving distance of the first clamp body 2 .

[0081] In some examples, conductive rods 53 are movably mounted on the inner walls of both sides of the chute, and insulating sheets 54 are connected to the two conductive rods 53. A power supply is installed inside the body 1 to supply power to various electrical appliances.

[0082] The distance between the two conductive rods 53 is equal to the width of the baffle 52, so that when the baffle 52 slides, the two conductive rods 53 can be connected;

[0083] A ring 55 is installed on the outside of each of the two conductive rods 53, and one of the rings 55, the power supply, the hydraulic telescopic rod 8 and the other ring 55 are connected in series in sequence through wires. Therefore, when the baffle 52 is in contact with the two conductive rods 53, the battery can keep supplying power to the hydraulic telescopic rod 8. When the baffle 52 is not in contact with the conductive rod 53, a short circuit is formed between the conductive rods 53, and the hydraulic telescopic rod 8 is in a power-off state and no longer extends, thereby controlling the depth of the crimping.

[0084] In some examples, one end of the conductive rod 53 is connected to the insulating sheet 54, and the other end passes through the scale sheet 51 and corresponds to a slot provided inside the body 1. Therefore, when the insulating sheet 54 is slid, the conductive rod 53 can be driven to move synchronously, thereby adjusting the position of the conductive rod 53 (i.e., adjusting the crimping depth). When the blocking piece 52 slides out of the conductive rod 53, the power can be cut off.

[0085] The collar 55 is connected to the portion of the conductive rod 53 that passes through the scale plate 51 , thereby transmitting the positive and negative poles of the power supply to the two conductive rods 53 to form a switch.

[0086] During the specific implementation process, the insulating sheet 54 is first manually slid to move the conductive rod 53 to the end of the scale sheet 51, and then the hydraulic telescopic rod 8 is controlled to extend to crimp the joint. During crimping, the user observes the crimping depth of the joint through the gap between the clamp body components. When it reaches the required depth, the insulating sheet 54 is slid again to make the end of the conductive rod 53 just fit with the baffle 52. At this time, the crimping depth setting is completed;

[0087] During the next crimping, the hydraulic telescopic rod 8 is controlled to extend to crimp the joint. Since the baffle 52 and the first clamp body 2 move synchronously, when the baffle 52 moves out of the position between the two conductive rods 53, a short circuit is formed between the conductive rods 53, and the current cannot be transmitted to the hydraulic telescopic rod 8. The hydraulic telescopic rod 8 is in a power-off state and no longer extends, thereby controlling the crimping depth and performing timely power-off.

[0088] Example 4

[0089] Based on Example 1, this embodiment of the present application is a technical problem of measuring the crimping depth. The overall idea is as follows:

[0090] The front end of the body 1 is provided with a sleeve 6, and the outer portion of the sleeve 6 is provided with a rangefinder 4;

[0091] Among them, the detection end of the rangefinder 4 corresponds to the baffle 52 on the top of the first caliper body 2, so when the baffle 52 moves, the rangefinder 4 can detect the moving distance of the baffle 52, which is convenient for detecting whether it is pressed to the specified depth.

[0092] Finally, it should be noted that the above embodiments are merely examples for the purpose of illustrating the present invention and are not intended to limit the embodiments. Those skilled in the art will readily appreciate that other variations or modifications based on the above description are possible. It is not necessary and impossible to provide an exhaustive list of all embodiments. However, obvious variations or modifications arising therefrom remain within the scope of protection of the present invention.
