Description

Technical Field

[0001] This utility model belongs to the technical field of spacer installation for power transmission conductors, and specifically relates to a fixing mechanism for installing spacers in double-split power transmission conductors. Background Technology

[0002] The spacer fixing mechanism for double-split transmission lines is used to install robots to transport and suspend spacers on two transmission lines. Then, the spacers are locked to the transmission lines by pins, which can prevent external influences from affecting the two double-split transmission lines during operation and maintain a certain distance at all times.

[0003] Chinese invention patent application No. 202310049473.X, entitled "A Six-Wheel Drive Robot for Installing Spacer Bars on Double-Split Transmission Lines," includes a loading platform, a walking mechanism, a storage mechanism, a conveying mechanism, and an installation mechanism. The installation mechanism includes a support arm, an installation hook, and a fastening module (i.e., a fixing mechanism). The fastening module includes a push rod motor, a fixed shaft, a rolling bearing, a fixed seat, and a pin storage device. After the spacer bar is placed on two double-split transmission lines with the cooperation of the conveying mechanism and the installation hook, the rolling bearing extends under the drive of the push rod motor to press the hook of the spacer bar onto the main structure of the spacer bar. Then, the pin storage device moves inward along the linear guide rail (its pin hole aligns with the pin hole of the spacer bar). Finally, the triangular push plate pushes the pin outward under the drive of the micro screw motor until the pin is inserted into the pin hole (the triangular telescopic block of the pin unfolds).

[0004] When this fixing mechanism is in operation, there is a problem that the outer openable hook is pressed firmly onto the main structure of the spacer bar by the bearing alone. During the process of inserting the pin into the pin hole, relative displacement can easily occur between the spacer bar and the transmission line. That is, the spacer bar may move away from the pin along the transmission line under the thrust of the pin, which affects the normal and smooth insertion of the pin. In order to solve the above problems, it is necessary to develop a fixing mechanism for installing spacer bars of double-split transmission lines. Utility Model Content

[0005] The purpose of this invention is to overcome the shortcomings of the prior art and provide a fixing mechanism for installing spacer bars of double-split transmission lines that has a better temporary limiting effect on spacer bars and a more normal and smoother insertion of pins.

[0006] The purpose of this utility model is achieved as follows: A fixing mechanism for installing spacer bars of a double-split transmission line includes a carrying platform and two pairs of vertical support columns symmetrically located on both sides of the carrying platform. A lifting beam that can move up and down is erected between each pair of vertical support columns. The lifting beam is provided with a hook clamping part and a pin part located on one side of the hook clamping part. The hook clamping part is installed on the lifting beam through a clamp base. The upper end of the clamp base is provided with two meshing gears A. The two gears A are respectively symmetrically connected to two L-shaped clamping rods with the clamping direction facing inward through two gear shafts. A servo motor is installed on the clamp base. The output shaft of the servo motor is connected to a gear B. The gear B is meshed with one of the gears A. The lower end of the clamp base is provided with a push rod motor. The push rod of the push rod motor is located below the central axis of the two gears A and is inclined upward.

[0007] Preferably, a worm gear motor with its working shaft facing upward is located inside one of the vertical support columns on the loading platform. The working shaft of the worm gear motor is connected to a lead screw A via a coupling. The upper end of the lead screw A is rotatably connected to the inner side of the corresponding vertical support column. A lead screw B, symmetrically arranged with the lead screw A, is rotatably connected to the inner side of the other vertical support column on the same side. Flange-type ball nuts A and B are respectively fitted on the lead screw A and the lead screw B. The two ends of the lifting beam are movably connected to the lead screw A and the lead screw B via the flange-type ball nuts A and the flange-type ball nuts B, respectively.

[0008] Preferably, the upper end of the lead screw A is rotatably connected to the inner side of the vertical support column on the corresponding side through a bearing and bearing seat A, and the upper and lower ends of the lead screw B are rotatably connected to the inner side of the vertical support column on the corresponding side through two bearings and bearing seat B, respectively.

[0009] Preferably, the gear shaft is rotatably connected to the fixture base via at least one hole shaft connection structure.

[0010] Preferably, the push rod of the push rod motor has a pressure rod vertically provided at the outer end of the push rod.

[0011] Preferably, the hook clamping parts and the pin parts on the two lifting beams are symmetrically arranged.

[0012] Preferably, the pin portion is connected to one side of the clamp base via a pin base.

[0013] Preferably, the cross-section of the lifting beam is square or rectangular, and the lower part of the clamp base is provided with a corresponding square or rectangular hole. The clamp base is tightly fitted onto the lifting beam through the corresponding square or rectangular hole.

[0014] Preferably, the lower end of the pin base is provided with an L-shaped slot that matches the lifting beam. After the clamp base is tightly fitted onto the lifting beam, the pin base is tightly secured onto the lifting beam through its corresponding L-shaped slot.

[0015] Due to the adoption of the above technical solutions, the beneficial effects of this utility model are as follows: Based on the existing structure, this utility model improves the original fixed rear crossbeam into a lifting crossbeam and adds a hook clamping part. This allows the spacer bar to be laterally clamped by the hook clamping part during the insertion of the pin into the pin hole, effectively preventing relative displacement between the spacer bar and the power transmission line. Combined with the original push rod's compression limit, the two work together to provide a better temporary limiting effect on the spacer bar, thus making the insertion of the pin into the pin hole more normal and smooth. In summary, this utility model has the advantages of better temporary limiting effect on the spacer bar and more normal and smooth pin insertion. Attached Figure Description

[0024] The technical solution of this utility model will be further described in detail below with reference to the accompanying drawings.

[0025] like Figure 1 , Figure 2 , Figure 3 , Figure 4 , Figure 5 and Figure 6 As shown, this utility model provides a fixing mechanism for installing spacer bars of double-split transmission lines, including a loading platform 1 and two pairs of vertical support columns 2 symmetrically located on both sides of the loading platform 1. A lifting beam 3 that can move up and down is provided between each pair of vertical support columns 2. The lifting beam 3 is provided with a hook clamping part 4 and a pin part 5 located on one side of the hook clamping part 4. The hook clamping part 4 is installed on the lifting beam 3 through a clamp base 41. The upper end of the clamp base 41 is provided with two meshing gears A42. The two gears A42 are symmetrically connected to two L-shaped clamping rods 43 with the clamping direction facing inward through two gear shafts 48. A servo motor 46 is installed on the clamp base 41. The output shaft of the servo motor 46 is connected to a gear B45. The gear B45 is meshed with one of the gears A42. The lower end of the clamp base 41 is provided with a push rod motor 47. The push rod 471 of the push rod motor 47 is located below the central axis of the two gears A42 and is inclined upward.

[0026] Specifically, when the servo motor 46 is activated, it drives the gear B45 to rotate. The gear B45 drives the two gears A42 to rotate in opposite directions, which in turn drives the two L-shaped clamping rods 43 to rotate in opposite directions via the two gear shafts 48. That is, they simultaneously clamp inward or open outward, thereby achieving the clamping and release of the main structure of the spacer bar. The initial position of the two L-shaped clamping rods 43 is the open state.

[0027] On the loading platform 1, a worm gear motor 8 with its working shaft facing upward is located inside one of the vertical support columns 2. The working shaft of the worm gear motor 8 is connected to a lead screw A10 via a coupling 9. The upper end of the lead screw A10 is rotatably connected to the inner side of the corresponding vertical support column 2. On the same side, a lead screw B12 is rotatably connected to the inner side of the other vertical support column 2, which is symmetrically arranged with the lead screw A10. Flange-type ball nuts A11 and B13 are respectively fitted on the lead screw A10 and lead screw B12. The two ends of the lifting beam 3 are movably connected to the lead screw A10 and lead screw B12 via flange-type ball nuts A11 and flange-type ball nuts B13.

[0028] Specifically, two flange-type ball nuts are detachably and fixedly connected to the lower ends of the two lead screws at both ends of the lifting beam 3 via their own flanges. During operation, driven by the worm gear motor 8, the lead screw A10 rotates, and the flange-type ball nut A11 that cooperates with it converts the rotational motion of the lead screw A10 into linear motion, thereby driving the lifting beam 3 to move up and down along the lead screw A10. At the same time, the lead screw B12 and the flange-type ball nut B on the corresponding side follow and cooperate to make corresponding movements, and together stably push the lifting beam 3 to complete the up and down movement.

[0029] The upper end of lead screw A10 is rotatably connected to the inner side of the vertical support column 2 on the corresponding side through bearing and bearing seat A6. The upper and lower ends of lead screw B12 are rotatably connected to the inner side of the vertical support column 2 on the corresponding side through two bearings and bearing seat B7 respectively. Through the flexible rotation of the bearings, the rotation of the two lead screws can be made smoother and easier.

[0030] The gear shaft 48 is rotatably connected to the fixture base 41 through at least one hole shaft connection structure. The upper end of the gear shaft 48 is coaxially connected to the gear A42. The middle and lower ends of the gear shaft 48 are rotatably connected to the fixture base 1 through the hole shaft connection structure, wherein the hole shaft connection structure adopts the prior art.

[0031] The outer end of the push rod 471 of the push rod motor 47 is provided with a pressure rod 44, which is used to increase the contact area with the spacer hook and improve the squeezing effect.

[0032] To better accommodate the symmetrical structure used for the spacer bars, the hook clamping parts 4 and the pin parts 5 on the two lifting beams 3 are symmetrically arranged.

[0033] Specifically, the pin part 5 includes a pin base 51 and a pin inserter 52. The pin base 51 replaces the original linear guide rail. After the improvement, the pin part 5 is aligned with the insertion position between the pin and the pin hole by the up and down movement of the lifting beam 3. The pin inserter 52 is equivalent to the original pin storage device and adopts the original structure.

[0034] The pin part 5 is connected to one side of the clamp base 41 via the pin base 51. In order to facilitate installation on the lifting beam 3, the pin base 51 and the clamp base 41 can adopt an integral structure. In this way, the hook clamping part 4 and the pin part 5 can be installed on the lifting beam 3 as an integral structure, which is very convenient. Moreover, the positions of the two are relatively fixed, which is conducive to the work of inserting the pin into the pin hole.

[0035] To better determine and ensure the installation position of the fixing mechanism and the lifting beam 3, the cross-section of the lifting beam 3 is preferably a square or rectangular structure with sharp edges and corners. The lower part of the clamp base 41 is provided with a corresponding square or rectangular hole. Thus, the clamp base 41 can be tightly fitted onto the lifting beam 3 through its corresponding square or rectangular hole. After installation, the relative position between the two is fixed, which is beneficial to the stability and reliability of the subsequent installation of the spacer.

[0036] Correspondingly, the lower end of the pin base 51 is provided with an L-shaped slot that matches the lifting beam 3. Thus, after the clamp base 41 is tightly fitted onto the lifting beam 3, the pin base 41 can be tightly secured onto the lifting beam 3 through its corresponding L-shaped slot, which is beneficial to the installation and working stability of this fixing mechanism.

[0037] In specific implementation, this fixing mechanism is applicable to a six-wheel drive robot for installing spacer bars of double-split power transmission conductors, as described in application number 202310049473.X. Its worm gear motor 8, servo motor 46, push rod motor 47, and miniature lead screw motor of pin inserter 52 are respectively connected to the control system of the six-wheel drive robot and are controlled as a whole by the control system to complete the corresponding pin insertion work.

[0038] After the above installation is completed, this utility model can be put into use. After the spacer bar is placed on the two double-split transmission lines by the six-wheel drive robot, the robot control system controls the worm gear motor 8 to start working, driving the lifting beam 3 to rise to the working position where the pin aligns with the pin hole through lead screw A10 and lead screw B12. At this time, the worm gear motor 8 stops working. Then, the robot control system controls the servo motor 46 to start working, driving the two L-shaped clamping rods 43 to rotate inward by a certain angle through gear B45 and two gears A12. The two L-shaped clamping rods 43 clamp the spacer bar laterally. At this time, the servo motor 46 stops working. Then, the robot control system controls the push rod motor 47 to start working, pushing the pressure rod 44 inward. Once the hook of the spacer bar is inserted into place and close to the main structure of the spacer bar, the push rod motor 47 stops working. Finally, the robot control system controls the pin inserter 52 to start working, driving the pin to slowly insert into the pin hole of the spacer bar until the triangular telescopic block of the pin pops out, locking and securing the spacer bar. At this point, the pin inserter 52 stops working, and the pin insertion into the pin hole of this fixing mechanism is completed. Next, the robot control system sequentially controls the pin inserter 52 to work in reverse and reset, the push rod motor 47 to work in reverse and reset, the servo motor 46 to work in reverse and reset, and the worm gear motor 8 to work in reverse and reset. At this point, the work of this fixing mechanism is completed, and the robot can continue with subsequent work.

[0039] The above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
