[0026] In order to make the above-mentioned objects, features and advantages of the present invention more obvious and easy to understand, the specific embodiments of the present invention are described in detail below in conjunction with the accompanying drawings. In the following description, many specific details are set forth to facilitate a full understanding of the present invention. However, the present invention can be implemented in many other ways different from those described below, and those skilled in the art can make similar improvements without violating the connotation of the present invention, so the present invention is not limited by the specific embodiments disclosed below.

[0027] See also Figure 1 , an auxiliary device for power cable installation construction, comprising a base 1 provided with a fixed end 2 and a compensating and stabilizing mechanism 3, the fixed end 2 and the compensating and stabilizing mechanism 3 are symmetrically distributed on the left and right, and the symmetrically distributed fixed end 2 is located between the symmetrically distributed compensating and stabilizing mechanisms 3, wherein the left fixed end 2 clamps and fixes the cable on the left and reserves a certain amount at the right end of the cable for installing a joint, the right fixed end 2 clamps and fixes the cable on the right and reserves a certain amount at the left end of the cable for installing a joint, the left compensating and stabilizing mechanism 3 reserves and limits the position of the left cable, and the right compensating and stabilizing mechanism 3 reserves and limits the position of the right cable. During the work process, the cable is manually placed on the corresponding fixed end 2 and fixed, and then laid on the corresponding compensating and stabilizing mechanism 3 and fixed, and then the joint is installed. At this time, the cable is in a stable state under the fixation of the fixed end 2 and the compensating and stabilizing mechanism 3, which is convenient for the smooth installation of the joint. After the joint is installed, the compensating and stabilizing mechanism 3 releases the reserved The amount of cable, at the same time, the symmetrical fixed end 2 moves relatively, so that the left and right cables move relatively until the preliminary docking is completed. The preliminary docking here is the final connection when the joint is automatically buckled, that is, the fixed end 2 moves relatively to make the joint at the right end of the left cable and the joint at the left end of the right cable automatically align and buckle together, and when the joint is a threaded connection or other connection, the preliminary docking is to align the joint at the right end of the left cable with the joint at the left end of the right cable, so that it is convenient for manual operation to continue to fix the two joints together. The whole construction process can be completed smoothly by one person, which can effectively reduce labor costs and facilitate manual and quick completion of the installation of cable joints and cable connection work. Secondly, there is no need to manually fix the cable for a long time, which effectively reduces the labor intensity of manual work. At the same time, combined with the compensation stabilization mechanism 3 and the fixed end 2 to clamp and fix the cable, a stable and reliable construction environment is provided for the installation of the joint and the connection of the cable, which is conducive to fully improving the quality of the cable connection.

[0028] See also Figure 1The compensating and stabilizing mechanism 3 includes a supporting member 31 and a receiving seat 32 matched with the supporting member 31. The supporting member 31 includes a sliding member 311 and an arc-shaped limiting head 312. The receiving seat 32 includes a base 322 provided with an arc-shaped receiving area 321. The base 322 is fixedly installed on the base 1. The sliding member 311 is vertically slidably connected to the base 322. The arc-shaped limiting head 312 is fixedly connected to the sliding member 311 and faces the arc-shaped receiving area 321. When the cable is placed between the arc-shaped limiting head 312 and the arc-shaped receiving area 321, the sliding member 311 is moved downward, and the arc-shaped limiting head 312 moves accordingly and presses down the cable until the cable is clamped and fixed between the arc-shaped limiting head 312 and the arc-shaped receiving area 321. At this time, the arc-shaped limiting head 312 and the arc-shaped receiving area 321 are fixedly connected. The arc-shaped receiving area 321 is in an arc-shaped path state, and when the connector is installed, it is only necessary to move the sliding member 311 upward to release the arc-shaped limit head 312 from limiting the cable. As the fixed end 2 moves, the cable gradually returns to a straight state. During this process, the cable synchronously supplements the amount of cable required for the movement of the fixed end 2, so that there is no need to move the entire cable again during the initial docking of the cables, thereby fully improving the convenience and stability of the initial docking process of the cables, and thus helping to improve the efficiency and quality of the cable connection. Among them, the arc-shaped limit head 312 and the arc-shaped receiving area 321 are both provided with arc-shaped limit grooves 35, and the cable is limited and constrained by the arc-shaped limit grooves 35, so that the arc-shaped limit head 312 and the arc-shaped receiving area 321 can clamp and fix the cable.

[0029] See also Figure 1 , Figure 2 and Figure 4The fixed end 2 includes a sliding seat 23 provided with a first clamping head 21 and a second clamping head 22. The sliding seat 23 is connected to the base 1 by sliding left and right. The first clamping head 21 in the left fixed end 2 is located on the left side of the second clamping head 22, and the first clamping head 21 in the right fixed end 2 is located on the right side of the second clamping head 22. The second clamping head 22 and the first clamping head 21 clamp the cable synchronously, and in the process of relative sliding of the fixed end 2, the second clamping head 22 on the left slides to the right to correct the cable between it and the corresponding joint, and the accuracy of the corresponding joint position is improved by correcting the position state of the cable. Similarly, the second clamping head 22 on the right slides to the left to correct the cable between it and the corresponding joint, thereby improving the position of the corresponding joint and improving the accuracy, thereby improving the accuracy, thereby improving the accuracy, thereby improving the accuracy, thereby improving the accuracy, thereby improving the accuracy, thereby improving the accuracy, thereby improving the accuracy, thereby improving the accuracy, thereby improving the accuracy, thereby improving the accuracy, thereby improving the accuracy, thereby improving the accuracy, thereby improving the accuracy, thereby improving the accuracy, thereby improving the accuracy, thereby improving the accuracy, thereby improving the accuracy, thereby improving the accuracy, So that the two joints can complete the initial docking smoothly and stably, and the stability and reliability of the work of the present invention are effectively improved. An elastic member 25 is connected between the sliding seats 23 in the symmetrical fixed end 2, and an automatic fastening member is arranged between the sliding seat 23 and the corresponding base 322. The automatic fastening member fixes the left sliding seat 23 and the left base 322 together, and fixes the right sliding seat 23 and the right base 322 together. At this time, the elastic member 25 is in a state of elastic deformation. When the sliding member 311 moves up, the automatic fastening member releases the state of fixed connection between the sliding seat 23 and the corresponding base 322. At this time, the sliding seat 23, under the action of the elastic member 25 and the ability of the cable to recover its own deformation, automatically slides relative to each other until the initial docking is completed.

[0030] See also Figure 1 , Figure 2 and Figure 6 The sliding seat 23 is provided with an automatic control component 24, which automatically controls the second clamping head 22 to move and correct the cables in the corresponding area, wherein the first clamping head 21 includes a moving part 211 symmetrically arranged front and back, and the moving part 211 is fixedly connected with a limited clamping part 212, and the second clamping head 22 includes a moving part 221, and the moving part 221 is connected with a limited clamping part 222, and the moving part 221 is connected to the moving part 211 by sliding left and right. One 211 is connected to the sliding seat 23 in a forward and backward sliding manner. When the cable is placed between the symmetrical limit clamping parts 212, the front and rear symmetrical moving parts 211 move relatively synchronously, so that the limit clamping parts 212 and the limit clamping parts 222 both clamp and fix the cable synchronously. Then, in the process of the sliding seats 23 sliding against each other, the automatic control component 24 automatically controls the movement of the moving part 221, so that the limit clamping parts 222 move accordingly to correct the cables in the corresponding area, thereby ensuring the accuracy of the joint position.

[0031] See also Figure 1 , Figure 6 and Figure 7The automatic control component 24 includes a connecting member 242 provided with a docking hole 241, the docking holes 241 are symmetrically distributed on the connecting member 242, the connecting member 242 is slidably connected to the sliding seat 23, the moving member 221 is fixedly connected with a docking rod 243, the docking rod 243 corresponds to the docking hole 241 one by one, the sliding seat 23 is slidably connected with an automatic control member 244, and the automatic control member 244 is limitedly slidably connected to the receiving seat 32, such as Figure 7 As shown, the automatic control member 244 is connected to the receiving seat 32 for sliding movement left and right, and a limit member 246 is fixedly connected to the receiving seat 32, and the limit member 246 limits the sliding range of the automatic control member 244. A gear rack assembly 245 is provided between the automatic control member 244 and the connecting member 242, as shown in FIG. Figure 6 As shown, during the relative movement of the moving member 1 211, the moving member 221 moves accordingly and the docking rod 243 thereon is inserted into the corresponding docking hole 241. Then, during the relative sliding of the sliding seat 23, before the joint is about to complete the preliminary docking, the automatic control member 244 on the left sliding seat 23 stops moving under the limit of the upper limit member 246 on the receiving seat 32. At this time, as the left sliding seat 23 continues to slide, the corresponding connecting member 242 is driven to slide to the right through the corresponding gear rack assembly 245, thereby causing the moving member 221 on the left to slide to the right, and the automatic control member 244 on the left sliding seat 23 stops moving under the limit of the upper limit member 246 on the receiving seat 32. The limiting clamping member 222 slides to the right to correct the cables in the corresponding area. Similarly, the automatic control member 244 on the right sliding seat 23 stops sliding under the limit of the upper limiting member 246 on the right sliding seat 23, and drives the right connecting member 242 to slide to the left through the corresponding gear rack assembly 245, thereby making the limiting clamping member 222 on the right moving member 221 slide to the left to correct the cables in the corresponding area. The entire correction process and the preliminary docking process do not require manual participation, which effectively improves the efficiency and convenience of cable connection and reduces manual labor intensity.

[0032] See also Figure 1 , Figure 3 , Figure 4 and Figure 5A limited position fixing assembly 33 is provided between the sliding member 311 and the base 322. The limited position fixing assembly 33 includes a switching seat 333 provided with a first rack 331 and a second rack 332, a pawl 1 334 meshing with the first rack 331, and a pawl 2 335 meshing with the second rack 332. The switching seat 333 is slidably connected to the base 322 front and back. The first rack 331 and the second rack 332 are fixedly installed on the switching seat 333 in sequence from front to back. In the process of the sliding member 311 moving downward, the first rack 331 is meshed with the pawl 1 334, and the pawl 2 335 is staggered with the second rack 332 front and back. At this time, the sliding member 311 can only move downward but cannot move upward. The worker only needs to press the sliding member 311 to move it downward to quickly make the arc-shaped limit head 312 clamp and fix the cable, which effectively improves the convenience of cable connection construction. In the process of moving the sliding member 311 upward, it is only necessary to move the switching seat 333 forward first, so that the first rack 331 and the pawl 1 334 are staggered front and back, and the second rack 332 is engaged with the pawl 2 335. At this time, the sliding member 311 can only move upward but cannot move downward. The worker only needs to move the sliding member 311 upward to quickly release the clamping and fixing of the cable by the arc-shaped limit head 312, wherein a flexible layer is provided on the clamping and fixing surface of the arc-shaped limit head 312 to improve the stability and reliability of the cable clamping and fixing state.

The unified control part 34 uniformly controls the movement of the sliding part 311 to release the limiting fixation of the cable by the supporting part 31. When the switching seat 333 moves forward, the first rack 331 and the ratchet 1 334 are staggered front and back, and the second rack 332 and the ratchet 2 335 are engaged, the unified control part 34 is moved upward, and the sliding part 311 can be uniformly controlled to move upward, which further improves the convenience of use of the present invention. In the process of moving the unified control part 34 upward, the automatic buckle part is passed and the automatic buckle part is pressed to automatically release the fixed connection state between the sliding seat 23 and the corresponding base 322 without manual pressing.

The limit clamp 1 212 with a plate-like structure stably and reliably clamps and fixes the cable, while the bent structure can automatically center the cable. The limit clamp 222 with a columnar structure clamps and fixes the cable and centers it, while reducing the contact area with the cable, making it easy to move and correct the cable. A contact sleeve 223 is provided on the rotating sleeve of the limit clamp 222, and the contact sleeve 223 contacts the cable. During the correction process, the friction between the limit clamp 222 and the cable is further reduced, thereby improving the smoothness and stability of the correction work.

[0035] See also Figure 2 and Figure 6 , one of the linear limiting areas of the limiting clamping member 1 212 and the limiting clamping member 222 is longer than the other linear limiting area, such as Figure 6 As shown, both the limit clamp 1 212 and the limit clamp 222 include an upper straight limit area and a lower straight limit area. The upper straight limit area and the corresponding lower straight limit area are distributed in a V shape, and the length of the upper straight limit area is smaller than the length of the lower straight limit area, which is convenient for placing the cable between the symmetrical limit clamp 1 212 and the symmetrical limit clamp 2 222 from above, and the cable will not fall from below, which is conducive to quickly and stably clamping and fixing the cable.
