Description

Technical Field

[0001] This invention relates to the field of conductor rail installation, specifically to a conductor rail support auxiliary construction device and a construction method for conductor rail installation. Background Technology

[0002] In industrial engineering, high-voltage heavy-duty rigid conductor rails are the power supply system for heavy-duty, large-tonnage overhead cranes. The main installation method involves welding the steel brackets of the conductor rail to the stiffening plates of the crane beam, installing high-voltage porcelain insulators on the brackets, and then installing the heavy-duty rigid conductor rail. The difficulty in construction lies in the need for high-altitude work tens of meters above the ground. Because the installation of the conductor rail requires precise positioning, the positioning requirements must be met when installing the conductor rail brackets. However, due to the heavy weight of the conductor rail brackets, a single person cannot complete the installation independently. Therefore, two workers are required to stand in the suspended platform simultaneously. One worker must lift the conductor rail bracket by hand and position it on the side of the crane beam. In addition to positioning the conductor rail bracket on the crane beam, the installation end of the conductor rail bracket also needs to be horizontally positioned. After the conductor rail bracket is positioned, another construction worker is needed to weld the fixed end of the conductor rail bracket to the crane beam. Since the conductor rail bracket has a certain weight, the construction worker will get tired from lifting the conductor rail bracket for a long time, which will cause positioning errors and affect the installation quality of the conductor rail. Summary of the Invention

[0003] In view of the shortcomings of the prior art, the technical problem to be solved by the present invention is: an auxiliary construction device for sliding contact line supports that improves the installation and positioning accuracy of the sliding contact line supports and reduces the workload of construction personnel.

[0004] To solve the above-mentioned technical problems, the present invention adopts the following technical solution:

[0005] A sliding contact line support auxiliary construction device includes a cage. Vertically extending suspension rods are fixedly connected to the left and right ends of the front side of the cage. Two vertically spaced suspension rollers capable of rolling in the left-right direction are installed at vertical intervals on the front side of each suspension rod. An adjusting sleeve is horizontally installed at the upper end of each suspension rod, extending in the front-back direction. The upper end of the suspension rod is fixedly connected to the sleeve body of the adjusting sleeve. A supporting crossbar, aligned with the center line, is installed inside the adjusting sleeve, capable of sliding along its length. Both ends of the rod extend out of the adjusting sleeve. A limiting thread is provided on the rear end of the supporting crossbar extending forward along its length. A limiting nut, threaded with the limiting thread, is provided on the supporting crossbar behind the adjusting sleeve. The limiting nut abuts against the rear end of the adjusting sleeve to limit its movement. A rail connecting slide is provided below the supporting crossbar in front of the adjusting sleeve. The top of the rail connecting slide is fixedly connected to the supporting crossbar. The supporting crossbar is located between the rail connecting slide and the adjusting sleeve. The body is fitted with a supporting horizontal tube that is fixedly connected to it. A supporting vertical tube extending downwards in the vertical direction is fixedly connected to the lower side of the supporting horizontal tube. The extended center line of the supporting vertical tube intersects with the extended center line of the supporting horizontal tube. A limiting protrusion is formed on the inner wall of the supporting vertical tube, extending from one end of the supporting vertical tube to the other along its length. A supporting vertical rod is provided below the supporting vertical tube along the center line. A limiting groove is provided on the upper end of the supporting vertical rod extending downwards along its length. The upper end of the supporting vertical rod is inserted into... The supporting vertical tube is inserted into the limiting groove, and the supporting vertical rod can slide along the length of the supporting vertical tube. The limiting protrusion can slide along the length of the limiting groove. The upper end of the supporting vertical rod is provided with a supporting thread extending downward along its length. The supporting vertical rod outside the supporting vertical tube is provided with a supporting nut that is threaded with the supporting thread. The supporting nut abuts against the lower end of the supporting vertical tube. The lower end of the supporting vertical rod is horizontally installed with a supporting roller that can roll in the left and right directions.

[0006] Two vertically oriented slide rails, facing each other in the left-right direction, are fixedly connected to the inner bottom surface of the cage by fixing bolts. The projections of the two slide rails in the front-back direction are located inside the projections of the two suspension rods in the front-back direction. A slide block is installed between the two slide rails, and the slide block is slidably connected to the slide rails on both sides to allow it to slide vertically. A lifting seat is installed between the tops of the two slide rails, and the lifting seat is fixedly connected to the slide rails on both sides. A slide block lifting device is installed on the lifting seat, which acts on the slide block to drive it to slide vertically. Two rods extending in the front-back direction are spaced apart vertically on the slide block. The horizontal sliding rods can slide and engage with the slide block in the front-back direction. The front ends of the two horizontal sliding rods are provided with vertically extending mounting rods. The two horizontal sliding rods are fixedly connected to the mounting rods respectively. On the front side of the mounting rods, two mounting crossbars extending forward in the front-back direction are fixedly connected at intervals in the vertical direction. The slide block is also equipped with an elastic tensioning device. One end of the elastic tensioning device is fixedly connected to the slide block, and the other end is detachably connected to the horizontal sliding rods to provide spring force for the horizontal sliding rods to move forward. The front side of the cage has a notch that allows the mounting rods and the sliding contact line bracket to be installed to extend out of the cage.

[0007] In this invention, when in use, first install two support crossbars, which are spaced apart along the extension direction of the rails at the top of the traveling beam. Align the rail connecting slides on the support crossbars with the rails at the top of the traveling beam, place the support rollers on the outside of the rails, install the rail connecting slides to slide them onto the rails, adjust the support nuts, and then adjust the extension length of the support vertical rods below the support nuts to ensure that the support rollers abut against the top surface of the traveling beam located outside the rails. The end of the support crossbar facing the outside of the traveling beam extends horizontally outward from the traveling beam, and the centerline of the support crossbar is perpendicular to the extension direction of the rails.

[0008] Next, install the hoist cage and lower it to the outer side of the trolley beam, with the front side of the hoist cage facing the direction of the trolley beam. The adjusting sleeves at the upper ends of the two suspension rods correspond to the two support crossbars respectively. Slide the adjusting sleeves onto the corresponding support crossbars. Move the hoist cage towards the side of the trolley beam, and make the two suspension rollers on the suspension rods abut against the upper and lower flanges of the trolley beam respectively. Slide the limiting nut, which is threaded with the limiting thread, onto the support crossbar behind the adjusting sleeve. The limiting nut abuts against the rear end of the adjusting sleeve to limit the adjustment sleeve.

[0009] Then, the construction workers entered the hoist cage. The operator pushed the support crossbars on top of the crane beam, causing the track connecting slide to move on the rails, moving the hoist cage to the installation position of the sliding contact line bracket. The construction workers then activated the slide lifting device to raise the slide, lifting the two installation crossbars above the crane beam. The operator then fixed the installation end of the sliding contact line bracket to the two installation crossbars on the crane beam using bolts. Simultaneously, the operator adjusted the level of the sliding contact line bracket to complete its horizontal positioning. After the operator had adjusted and fixed the sliding contact line bracket, the construction workers activated the slide lifting device to lower the slide, lowering the sliding contact line bracket... Once inside the hoisting cage, the construction workers push the horizontal slide bar forward, propelling the conductor rail bracket towards the trolley beam. The height of the conductor rail bracket is adjusted using the sliding seat lifting device. After the conductor rail bracket is vertically positioned, the end of the elastic tensioning device furthest from the sliding seat is fixed to the horizontal slide bar, thus pressing the fixed end of the conductor rail bracket against the side of the trolley beam. The construction workers then weld the fixed end of the conductor rail bracket to the trolley beam, remove the bolts connecting the conductor rail bracket to the installation crossbar, and disconnect the elastic tensioning device from the horizontal slide bar. Finally, the horizontal slide bar is pulled backward, causing the installation crossbar to move back into the hoisting cage.

[0010] As an optimization, the slide lifting device includes a lifting stepper motor fixed on a lifting base. A motor shaft extends vertically from the bottom of the lifting stepper motor. The lifting base has a vertically oriented motor shaft hole corresponding to the position of the motor shaft, allowing the motor shaft to enter. A lifting screw is positioned below the motor shaft along its center line. The upper end of the motor shaft and the lifting screw are connected in a driving connection. The diameter of the motor shaft hole is larger than both the diameter of the motor shaft and the outer diameter of the lifting screw. The lifting screw passes through the slide and is threaded into it. The lower end of the lifting screw is rotatably connected to the inner bottom surface of the cage. The stepper motor allows for precise control of the slide's lifting and lowering, facilitating vertical positioning of the sliding contact line bracket.

[0011] As an optimization, the slide block is vertically threaded with a lifting threaded hole corresponding to the position of the lifting screw. The lifting screw includes multiple spliced ​​screws, with extension rods extending outward from both ends of each spliced ​​screw along its centerline. The diameter of the extension rods is smaller than the outer diameter of the spliced ​​screw. The multiple spliced ​​screws are fixedly connected together along the centerline through their end extension rods. The sum of the lengths of two extension rods is less than the length of the lifting threaded hole. Because the lifting height is relatively high, the corresponding length of the lifting screw is relatively long. However, long-distance screws are more difficult to manufacture. Therefore, the entire lifting screw is spliced, with the ends of the spliced ​​screws concentrically connected. Furthermore, the sum of the lengths of two extension rods is less than the length of the lifting tube. This ensures that adjacent spliced ​​screws always maintain thread engagement with the lifting tube, without affecting the overall use.

[0012] As an optimization, the elastic tensioning device includes a vertically arranged tensioning rod located between the two horizontal sliding rods. Both ends of the tensioning rod are fixedly connected to the two horizontal sliding rods. A tensioning sliding hole is provided on the tensioning rod along a direction parallel to the center line of the horizontal sliding rods. A tensioning sliding groove is formed on the upper wall of the tensioning sliding hole along a direction parallel to the center line of the tensioning sliding hole. The tensioning sliding groove is a through groove. A tensioning crossbar, capable of slidingly engaging with the tensioning sliding hole along its center line, is inserted into the tensioning sliding hole. A tensioning strip is formed on the crossbar, extending from one end to the other along the length of the crossbar. The tensioning strip extends into the tensioning sliding groove and... The tensioning crossbar is capable of sliding along the length of the tensioning groove. Multiple tensioning positioning holes are evenly spaced along its length, extending along a plane perpendicular to the center lines of the two horizontal sliding rods. A tensioning fixing hole is provided on the tensioning vertical rod at a position corresponding to the tensioning sliding hole, extending along a plane perpendicular to the center lines of the two horizontal sliding rods. A tensioning positioning pin is inserted into the tensioning fixing hole, allowing it to pass through the corresponding tensioning positioning hole to position and fix the tensioning crossbar. A tensioning spring is provided at one end of the tensioning crossbar facing the slide block, with both ends of the spring fixedly connected to the tensioning crossbar and the slide block, respectively. When the slide block is raised to facilitate horizontal positioning of the conductor rail bracket by the operator, the tensioning crossbar and tensioning vertical bar are not locked by tensioning positioning pins. This facilitates positioning for the operator. After positioning, when welding the conductor rail bracket to the trolley beam, the positions of the conductor rail bracket and the trolley beam need to be stabilized. The operator can then pull the tensioning crossbar backward, stretching the tensioning spring. By aligning the corresponding tensioning positioning holes and tensioning fixing holes on the tensioning crossbar, the operator inserts the tensioning positioning pins to lock the tensioning crossbar and tensioning vertical bar. The return spring force generated by the tensioning spring then pulls the horizontal slide bar towards the trolley beam, thus stabilizing the conductor rail bracket on the trolley beam and facilitating welding and fixing by the operator.

[0013] A construction method for installing a heavy-duty rigid conductor rail, using the aforementioned conductor rail support auxiliary construction device, includes the following steps:

[0014] (1) Install two support crossbars. The support crossbars are spaced apart along the extension direction of the rails at the top of the trolley beam. The rail connecting slide on the support crossbar is aligned with the rail at the top of the trolley beam. The support roller is placed on the outside of the rail. The rail connecting slide is installed and slidably connected to the rail. The support nut is adjusted, and then the extension length of the support vertical bar below the support nut is adjusted to ensure that the support roller abuts against the top surface of the trolley beam located outside the rail. The end of the support crossbar facing the outside of the trolley beam extends horizontally outward from the trolley beam, and the center line of the support crossbar is perpendicular to the extension direction of the rail.

[0015] (2) Install the hoist cage and lower it to the outer side of the trolley beam. The front side of the hoist cage faces the direction of the trolley beam. The adjusting sleeves at the upper ends of the two suspension rods correspond to the two support crossbars respectively. Put the adjusting sleeves onto the corresponding support crossbars respectively. Move the hoist cage to the direction of the trolley beam. Make the two suspension rollers on the suspension rods abut against the upper and lower wing sides of the trolley beam respectively. Put the limiting nut that is threaded with the limiting thread on the support crossbar behind the adjusting sleeve. The limiting nut abuts against the rear end of the adjusting sleeve to limit the adjusting sleeve.

[0016] (3) Construction personnel enter the hoist cage. The operator pushes the support crossbar on the top of the crane beam to move the rail connecting slide on the rail, moving the hoist cage to the installation position of the sliding contact line bracket. The construction personnel start the slide lifting device to drive the slide to rise, raising the two installation crossbars above the crane beam. The operator fixes the installation end of the sliding contact line bracket to the two installation crossbars on the crane beam with bolts. At the same time, the operator adjusts the level of the sliding contact line bracket to complete the horizontal positioning of the sliding contact line bracket. After the operator adjusts and fixes the sliding contact line bracket, the construction personnel start the slide lifting device to drive the slide to descend, bringing the sliding contact line bracket into the hoist cage. The construction personnel push the horizontal slide bar forward to move the sliding contact line bracket. Pushing towards the trolley beam, the height of the sliding contact line bracket is adjusted using the sliding seat lifting device. After the sliding contact line bracket is vertically positioned, the end of the elastic tensioning device away from the sliding seat is fixed to the horizontal sliding rod, so that the fixed end of the sliding contact line bracket is pressed against the side of the trolley beam. The construction workers weld the fixed end of the sliding contact line bracket to the trolley beam, remove the bolt connection between the sliding contact line bracket and the installation crossbar, remove the connection between the elastic tensioning device and the horizontal sliding rod, and then pull the horizontal sliding rod backward to move the installation crossbar back into the cage. The operators continue to push the support crossbar to move the rail connecting sliding seat on the rail, install the next sliding contact line bracket, until all sliding contact line brackets are installed.

[0017] (4) Install high-voltage insulators sequentially on the sliding contact line support;

[0018] (5) Place all the sliding contact lines on the mounting end of the sliding contact line bracket in sequence along the extension direction of the rail. After all the sliding contact lines are placed, place the sliding contact line clip on the top of the high voltage insulator.

[0019] (6) Position and adjust the high voltage insulator, adjust the horizontal and vertical deviations of the sliding contact line, fix the high voltage insulator on the sliding contact line bracket after adjustment, and connect all adjacent sliding contact lines.

[0020] During construction, only one worker is needed inside the hoist cage. The operator, positioned on the top surface of the trolley beam, first moves and adjusts the hoist cage to the installation position. Then, the installation vertical rod is raised above the trolley beam to facilitate the operator's horizontal positioning and pre-fixing of the sliding contact line bracket onto the installation crossbar. Due to the ample operating space and minimal interference on the trolley beam, the operator can easily adjust the horizontal level of the sliding contact line bracket. After adjustment, the installation vertical rod is lowered, and its vertical position is adjusted according to the distance between the installation end on the sliding contact line and the top surface of the rail. After vertical positioning, the horizontal sliding rod is pushed forward, causing the sliding contact line bracket to move towards the trolley beam and abut against the side of the trolley beam. At the installation location; after the conductor rail bracket is positioned, the construction personnel operate the elastic tensioning device on the horizontal sliding rod. This provides elastic force to ensure the conductor rail bracket is firmly pressed against the side of the crane beam, eliminating the need for additional construction personnel to continuously lift the conductor rail bracket by hand, thus saving labor costs. The conductor rail bracket is also firmly positioned, and the construction personnel inside the cage only need to weld the conductor rail bracket. This avoids deviations in the installation positioning of the conductor rail bracket caused by human factors, and also avoids the situation where adjacent conductor rails are not on the same plane when subsequently installed on the conductor rail bracket, thereby improving construction efficiency and installation quality.

[0021] Compared with existing technologies, this invention is simple to operate, which can not only reduce labor costs, but also reduce the workload of construction workers, and improve the positioning accuracy of the conductor rail bracket and the installation quality of the conductor rail.

[0031] A construction method for installing a heavy-duty rigid conductor rail, using the aforementioned conductor rail support auxiliary construction device, includes the following steps:

[0032] (1) Install two support crossbars 5. The support crossbars 5 are spaced apart along the extension direction of the rail at the top of the traveling beam. The rail connecting slide 7 on the support crossbar 5 is aligned with the rail at the top of the traveling beam. The support roller 12 is placed on the outside of the rail.

The end of the support crossbar 5 facing the outside of the traveling beam extends horizontally outward from the traveling beam, and the center line direction of the support crossbar 5 is perpendicular to the extension direction of the rail.

[0033] (2) Install the cage 1 and lower the cage 1 to the outer side of the traveling beam. The front side of the cage 1 faces the direction of the traveling beam. The adjusting sleeves 4 at the upper end of the two suspension rods 2 correspond to the two support crossbars 5 respectively. Put the adjusting sleeves 4 onto the corresponding support crossbars 5 respectively. Move the cage 1 so that the cage 1 moves towards the side of the traveling beam. And make the two suspension rollers 3 on the suspension rods 2 abut against the upper wing plate side and the lower wing plate side of the traveling beam respectively. Put the limiting nut 6 that is threaded with the limiting thread on the rod body of the support crossbar 5 located behind the adjusting sleeve 4.

[0034] (3) Construction personnel enter the hoist cage 1. The operator pushes the support crossbar 5 on the top of the crane beam to move the rail connecting slide 7 on the rail, moving the hoist cage 1 to the installation position of the sliding contact line bracket. The construction personnel start the slide lifting device 16 to drive the slide 14 to rise, raising the two installation crossbars 19 to above the crane beam. The operator fixes the installation end of the sliding contact line bracket to the two installation crossbars 19 on the crane beam with bolts. At the same time, the operator adjusts the level of the sliding contact line bracket to complete the horizontal positioning of the sliding contact line bracket. After the operator adjusts and fixes the sliding contact line bracket, the construction personnel start the slide lifting device 16 to drive the slide to descend, bringing the sliding contact line bracket into the hoist cage 1. The construction personnel push the horizontal slide bar 17 forward to move the sliding contact line bracket. Pushing towards the trolley beam, the height of the sliding contact line bracket is adjusted by the sliding seat lifting device 16. After the sliding contact line bracket is vertically positioned, the end of the elastic tensioning device away from the sliding seat 14 is fixed to the horizontal sliding rod 17, so that the fixed end of the sliding contact line bracket is pressed against the side of the trolley beam. The construction personnel weld the fixed end of the sliding contact line bracket to the trolley beam, remove the bolt connection between the sliding contact line bracket and the installation crossbar 19, remove the connection between the elastic tensioning device and the horizontal sliding rod 17, and then pull the horizontal sliding rod 17 backward to move the installation crossbar 19 back into the cage 1.
