Description

Technical Field

[0002] Power lines refer to facilities used to transmit and distribute electrical energy. They are an important part of the power system, used to connect power stations with substations, as well as the power network from substations to end users. Power lines are pre-installed. The installation of power lines is a highly professional job that needs to be carried out in strict accordance with national or regional electrical specifications and standards.

[0003] There are generally two types of power line installation: one is laying cables in trenches, and the other is laying cables on overhead lines. When installing power lines in trenches, it is generally necessary to install a bridge in the trench in advance to support and organize the cables. The trough bridge is the most common type of bridge. It consists of a mounting plate and multiple beams and looks like a ladder. This design facilitates air circulation and also facilitates the installation and maintenance of cables.

[0004] The existing installation of trough-type bridges is mostly done manually. During work, workers are required to position and straighten a single bridge in advance. After the positioning is completed, a bolt-on device is used to fix the mounting plate of the bridge to the inner wall of the groove. In this way, workers can only complete the installation of one bridge at a time. The installation of general power lines is a large project, which is undoubtedly not conducive to ensuring the overall progress of the bridge. The work efficiency needs to be improved. In addition, the positioning of the bridge is also completed by a single person, and it needs to be done one by one, which further affects the work efficiency.

[0042] During specific operation, the motor 413 is operated to control the downward screw rod 414 to rotate, and the downward screw rod 414 controls the moving seat 42 to move along the guide rod 412, and the four sets of bridge frames that have been locked are driven to be lowered into the groove through the moving seat 42.

[0043] See also Figure 4 , Figure 5 and Figure 6The locking assembly 44 includes a first bidirectional electric push rod 442 fixedly connected to the front and rear sides of the moving seat 42. The output ends of the first bidirectional electric push rods 442 on the front and rear sides are fixedly connected to a frame 444 through a connecting frame 443. A limited sliding shaft 446 is rotatably connected between the front and rear walls of the frame 444 and is fixedly connected to a guide rod 447. Two front and rear arch frames 448 are arranged in the frame 444. The front arch frame 448 is movably arranged in the frame 444. The rear arch frame 448 is fixedly connected to the frame 444 through a locking frame 46. A bidirectional screw sleeve 445 is rotatably connected inside the arch frame 448 and is fixedly connected to a sliding sleeve 449. The two groups of clamps 43 in the clamp group are symmetrically threaded on the bidirectional screw sleeve 445 and slidably connected to the sliding sleeve 449; the locking assembly 44 also includes an electric push rod 45 fixedly connected to the upper end of the rear arch frame 448, and the output end of the electric push rod 45 is fixedly connected to the front arch frame 448 in the same frame 444. The front and rear bidirectional screw sleeves 445 in the same frame 444 are commonly limited and slidably connected to the limiting sliding shaft 446, and the front and rear sliding sleeves 449 in the same frame 444 are commonly slidably connected to the guide rod 447, and the limiting sliding shafts 446 on the left and right sides are commonly provided with a linkage component 441 for controlling their synchronous operation.

[0044] See also Figure 4 and Figure 5 The linkage component 441 includes a bevel gear 1 4414 fixedly connected to the front extension end of the left and right limiting sliding shafts 446, the periphery of the bevel gear 1 4414 is meshedly connected with a bevel gear 2 4416, the center of the bevel gear 2 4416 is fixedly connected with a connecting sleeve 4415, the connecting sleeve 4415 is rotatably connected to a support plate 4417, the support plate 4417 is fixedly connected to the front end of the frame 444, the connecting sleeves 4415 on the left and right sides are commonly limited and slidably connected to the limiting sliding shaft 1 4413, the limiting sliding shaft 1 4413 is rotatably connected to the support frame 4411, the support frame 4411 is fixedly connected to the front end of the moving seat 42, one end of the limiting sliding shaft 1 4413 extends to the outside of the support frame 4411 and is fixedly connected to the output end of the motor 2 4412, and the motor 2 4412 is fixedly connected to the outside of the support frame 4411.

[0045] During specific operation, the limit sliding shaft 1 4413 is controlled to rotate by the operation of the motor 2 4412, and the two bevel gears 2 4416 are synchronously driven to rotate by the connecting sleeves 4415 on the left and right sides. The bevel gear 1 4414 is driven to rotate and control the limit sliding shaft 2 446 through the bevel gear 2 4416. The two-way screw sleeve 445 is controlled by the limit sliding shaft 2 446 to rotate and drive the two clamps 43 in the same clamping frame group to move in opposite directions, so as to lock the bridge frame crossbeam. By extending the first two-way electric push rod 442, the clamping frame group can be inserted into the front bridge frame. By shortening the first two-way electric push rod 442, it can be avoided that the clamping frame group interferes with the forward movement of the subsequent bridge frame. By controlling the front clamping frame group to move forward through the electric push rod 2 45, the front and rear bridge frames in the locked state can be separated to meet the specific bridge frame installation spacing requirements.

[0046] See also Figure 1 , Figure 2 , Figure 3 and Figure 7 The pushing assembly 51 includes a plurality of connecting plates 511 fixedly connected to the upper end of the mounting frame 3 symmetrically on the left and right sides, and a short rack 512 is fixedly connected to one end of the plurality of connecting plates 511 on the same side away from the mounting frame 3. A guide frame 514 is provided on the side of the short rack 512 away from the mounting frame 3. The guide frame 514 is fixedly connected to the inner wall of the frame 1 through a fixed plate. A long rack 516 is slidably embedded in the guide frame 514. The length of the short rack 512 corresponds to the width of the two bridge frames. The front ends of the short rack 512 and the long rack 516 are flush. The short rack 512 and the long rack 516 are meshed and connected to the lower gear 515 on the side close to each other. The lower gear 515 is connected by A one-way rotating bearing (which is prior art and will not be described in detail here) is installed on the rotating pin 517, and the two rotating pins 517 are connected to the fixed frame 518 by rotating together. The fixed frame 518 is fixedly connected to the inner wall of the frame 1 through a fixed seat. An upper gear 513 is arranged above the lower gear 515, and the upper gear 513 is fixedly connected to the rotating pin 517. The two upper gears 513 are meshed and connected. A support rod 519 is fixedly connected to the rear end of the long rack 516, and a mounting block 5110 is fixedly connected to the rear end of the support rod 519. An electric push rod four 5111 is fixedly connected to the mounting block 5110, and the output end of the electric push rod four 5111 is downward and fixedly connected to a push bar 5112.

[0047] During specific operation, the connecting plate 511 is driven forward to control the movement of the short rack 512 through the forward movement of the mounting frame 3, and the short rack 512 controls the rotation of the lower gear 515 meshing therewith, and the lower gear 515 is connected through a one-way rotating bearing. When the short rack 512 moves forward, the lower gear 515 can drive the rotating pin 517 to rotate, and vice versa, the rotating pin 517 cannot rotate. When the rotating pin 517 rotates, the lower gear 515 on the other side is controlled to rotate through the meshing of the two upper gears 513, thereby driving the long rack 516 to move synchronously, and the long rack 516 drives the push bar 5112 to move forward through the support rod 519 and the mounting block 5110, so that the mounting frame 3 moves forward and the push bar 5112 moves forward. Maintain synchronization and, through the linkage effect, keep the subsequent bridge frames able to be automatically supplemented. When the mounting frame 3 is reset and moved backward, the lower gear 515 reverses and will not drive the rotating pin 517 connected to it to rotate. The push bar 5112 remains in its original position. When the entire bridge frame is pushed, the push bar 5112 is manually pulled, and the long rack 516 is driven by the push bar 5112 to move. The lower gear 515 meshing with the long rack 516 also reverses and will not drive the rotating pin 517 connected to it to rotate. The short rack 512 remains in its original position, and the height of the push bar 5112 is controlled by the electric push rod four 5111 to avoid interference with the supplemented bridge frame when the push bar 5112 moves backward.

[0048] See also Figure 2 The horizontal wall and the vertical walls on both sides of the guide slot frame 54 are provided with mounting slots. A number of equally spaced rollers 541 are rotatably connected in the mounting slot of the horizontal wall, and a number of equally spaced rollers 542 are rotatably connected in the mounting slot of the vertical wall. The upper and lower edges of the mounting plates of the bridge frame are correspondingly slidably connected in the guide slot frames 54 on the upper and lower sides.

[0049] During specific operation, the roller 1 541 and the roller 2 542 are in rolling contact with the bridge frame, so as to ensure that the bridge frame can move forward smoothly.

[0050] See also Figure 4 The clamp frame 43 is detachably installed.

[0051] During specific operation, the clamp frame 43 is configured to be composed of an upper and lower part, the upper structure and the lower structure are detachably connected by bolts, the upper structure is installed in the arch frame 448, and the lower structure locks the bridge frame. The detachable structure can replace the lower structure that meets the installation requirements according to the thickness of the bridge frame's beams, and the locking requirements for different bridge frame beams can be met by changing the clamp groove type. Multiple clamp grooves are provided on a single lower structure, and a beam is locked in each clamp groove. The method of locking multiple beams can increase the contact points, and the multi-point locking method is used to ensure the installation verticality of the bridge frame.

[0052] See also Figure 1-Figure 8When in use: S1: The whole device is controlled to move along the groove through the traction device, and the driving wheels 112 roll on both sides of the groove. After moving to the installation position, the first bidirectional electric push rod 442 is extended to make the clamping frame group insert into the front bridge frame, and then the motor 2 4412 is operated to control the rotation of the limit sliding shaft 1 4413, and the connecting sleeves 4415 on the left and right sides synchronously drive the two bevel gears 2 4416 to rotate, and the bevel gear 1 4414 is driven by the bevel gear 2 4416 to rotate and control the rotation of the limit sliding shaft 2 446, and the bidirectional screw sleeve 445 is controlled by the limit sliding shaft 2 446 to drive the two clamping frames 43 in the same clamping frame group to move in opposite directions to lock the bridge frame crossbeam.

[0053] S2: The electric push rod 411 is used to control the installation frame 3 to move forward, and the front four bridge frames are moved out of the guide groove frame 54. Then, the motor 413 is used to control the rotation of the downward screw rod 414. The downward screw rod 414 controls the moving seat 42 to move along the guide rod 412. The four bridge frames are driven to be lowered into the groove after being locked by the moving seat 42. In the synchronous state, the forward movement of the installation frame 3 will also drive the connecting plate 511 to control the movement of the short rack 512. The short rack 512 controls the rotation of the lower gear 515 meshing with it. The lower gear 515 rotates in one direction. The lower gear 515 is connected with the short rack 512, and when it moves forward, it can drive the swivel pin 517 to rotate. Otherwise, the swivel pin 517 cannot rotate. When the swivel pin 517 rotates, the long rack 516 is controlled to move synchronously through the meshing of the two upper gears 513. The long rack 516 drives the push bar 5112 to move forward through the support rod 519 and the mounting block 5110. In this way, the forward movement of the mounting frame 3 and the forward movement of the push bar 5112 are kept synchronized, and the push bar 5112 pushes the subsequent bridge frame to the front, and the pushing distance is the same as the forward movement distance of the four groups of bridge frames in front.

[0054] S3: The above-mentioned four groups of positioned bridge frames remain in the lowered state, and the staff fixes each bridge frame on both sides of the groove in turn with bolts, then resets the clamping frame group, and then performs S2 again, continuously lowering the four groups of bridge frames into the groove. After all the bridge frames are pushed, the upper and lower guide groove frames 54 are expanded by controlling the second bidirectional electric push rod 53 to expand the distance, and the subsequent bridge frames are manually added to the guide groove frames 54, and it is ensured that the front four groups of bridge frames are in the position corresponding to the clamping frame group, and then the electric push rod 5111 controls the push bar 5112 to rise, and then manually pulls the push bar 5112, and the push bar 5112 drives the long rack 516 to move backward to the rear edge of the rearmost side bridge frame, and then the push bar 5112 is lowered to press the rear edge of the rearmost side bridge frame, and then S2 is performed.

For those skilled in the art, the present invention may have various modifications and variations.
