Description

Technical Field

[0001] The utility model relates to the technical field of use of a cable laying trolley in cable laying construction, in particular to a driving mechanism used on a cable laying trolley at an electric power construction site. Background Art

[0002] With the rapid development of power technology, power lines have been erected in various regions. During the construction of new lines and the reconstruction of old lines, rivers, mountains, and crossings of existing lines are often encountered. Under these natural conditions, large-scale machinery and construction personnel cannot directly complete the line installation in the traditional way of erecting power transmission lines. In general, drones or flying wire cars are used to lay out the lines. However, there are objective requirements such as no-fly zones during the drone laying process, and the corresponding laying work cannot be completed, which makes the work a bottleneck. Alternatively, if a flying wire car is used, operators are required to ride to complete the deployment of the traction rope and conductors. Since this work is an aerial operation, there are certain safety hazards.

[0003] In order to solve the above problems, technicians in relevant fields have proposed a wire-laying trolley to complete the deployment and recovery of traction ropes and conductors. The use of a wire-laying trolley can avoid the no-fly zone problem of traditional drones, solve the safety hazard problem of wire-laying trolleys, and improve construction efficiency. However, due to the different voltage levels of the installed power lines and the differences in the diameters of the wires used, the use of a wire-laying trolley with a uniform specification cannot meet the needs of power workers. At the same time, the running speed and operation mode of the wire-laying trolley on the traction rope and the wire also need to meet certain requirements to ensure its reliable and effective operation, and assist power construction personnel to complete the deployment and recovery of the wires and traction ropes with higher efficiency and quality.

[0046] like Figures 1 to 9 As shown, it shows the specific implementation of the utility model:

[0047] Example 1

[0048] The utility model discloses a driving mechanism for a wire pulling trolley at an electric power construction site, comprising a fixed-side synchronous belt mechanism 1, a movable-side synchronous belt mechanism 2, and a spacing adjustment mechanism 3. The fixed-side synchronous belt mechanism 1 is fixedly mounted on one side of the wire pulling trolley 4, the movable-side synchronous belt mechanism 2 is slidably mounted on the other side of the wire pulling trolley 4, and the spacing adjustment mechanism 3 is mounted on the lower surfaces of the fixed-side synchronous belt mechanism 1 and the movable-side synchronous belt mechanism 2, and is located on both sides of the frame 41 of the wire pulling trolley 4.

[0049] In this embodiment, Figure 1As shown, the driving mechanism controls the distance between the moving side synchronous belt mechanism 1 and the fixed side synchronous belt mechanism 2 through the spacing adjustment mechanism 3, so that the wire pulling trolley using the driving mechanism is suitable for traction ropes and conductors of different diameters, meeting the installation of lines of different voltage levels during the actual power line installation process, and has a wider range of applications.

[0050] The spacing adjustment mechanism 3 includes a first linear guide rail 31, a second linear guide rail 32, and a screw module 33. The first linear guide rail 31, the second linear guide rail 32, and the screw module 33 are installed on the inner side of the wire pulling trolley frame 41, and the screw module 33 is located in the middle position between the first linear guide rail 31 and the second linear guide rail 32.

[0051] The screw module 33 includes a screw fixing seat 331, a motor fixing seat 332, a screw motor 333, a screw 334, and a screw slide 335. The screw fixing seat 331 is fixedly mounted on the inner side of one side of the moving side synchronous belt mechanism 2 on the pulling trolley frame 41, and the motor fixing seat 332 is fixedly mounted on the inner side of one side of the fixed side synchronous belt mechanism 1 on the pulling trolley frame 41. The screw motor 333 is fixedly mounted on the motor fixing seat 332. The output shaft of the screw motor 333 is connected to one end of the screw 334, and the other end of the screw 334 is rotatably connected to the screw fixing seat 331. The screw slide 335 is provided with a connecting hole and is fixedly connected to the screw 334. One side of the screw slide 335 is fixedly connected to the track lower guard plate 16 of the moving side synchronous belt mechanism 2.

[0052] In this embodiment, Figure 1 、 Figure 2 As shown, the movement of the screw module 33 is used to realize the movement of the screw slide 335 on it, thereby moving the track lower guard plate 16 of the movable side synchronous belt mechanism 2 connected above the screw slide 335, driving the guide rail slider 314 on the first linear guide rail 31 and the second linear guide rail 32 on the lower surface of the track lower guard plate 16 to move on the guide rail 313, thereby realizing the adjustment of the distance between the movable side synchronous belt mechanism 2 and the fixed side synchronous belt mechanism 1. This driving method is reliable and effective.

[0053] In this embodiment, Figure 2As shown, after the screw motor 333 works, the screw 334 connected to the output end of the screw motor 333 rotates, so that the screw slide 335 fixedly mounted on the screw 334 moves along the rotation direction of the screw 334, thereby realizing the movement of its position. Since the screw slide 335 and the guide rail slider 314 are both connected under the crawler lower guard plate 16 of the moving side synchronous belt mechanism 2, when the position of the screw slide 335 changes, the distance between the moving side synchronous belt mechanism 2 and the fixed side synchronous belt mechanism 1 is adjusted, making it suitable for wires and traction ropes of different wire diameters. At the same time, the screw motor 333 is used for adjustment to avoid manual participation. The adjustment result is more accurate, greatly improving work efficiency.

[0054] Specifically, the first linear guide rail 31 and the second linear guide rail 32 have the same structure, including a first fixed block 311, a second fixed block 312, a guide rail 313, and a guide rail slider 314. The first fixed block 311 is fixedly installed on the inner side of one side of the pulling trolley frame 41, and the second fixed block 312 is fixedly installed on the inner side of the other side of the pulling trolley frame 41. One end of the guide rail 313 is installed on the first fixed block 311, and the other end is installed on the second fixed block 312. A sliding connection hole is provided in the middle of the guide rail slider 314, and the guide rail slider 314 is slidably connected to the guide rail 313 through the sliding connection hole. The upper surface of the guide rail slider 314 is fixedly connected to the lower track guard plate 16 of the moving side synchronous belt mechanism 2.

[0055] In this embodiment, Figure 2 As shown, the first fixed block 311 and the second fixed block 312 provide support for the guide rail 313, and the guide rail slider 314 can move on the guide rail 313. The first linear guide 31 and the second linear guide 32 are respectively located on both sides of the screw module 33. During the adjustment process of the screw module 33, the moving side synchronous belt mechanism 2 is driven to move, so that the entire moving side synchronous belt mechanism 2 moves as a whole, ensuring reliable and effective adjustment of the spacing.

[0056] Specifically, the fixed side synchronous belt mechanism 1 has the same structure as the movable side synchronous belt mechanism 2, including a main rotating shaft 11, a slave rotating shaft 12, a drive motor 13, a crawler 14, an upper crawler guard plate 15, and a lower crawler guard plate 16. The drive motor 13 is installed on the upper surface of the bottom plate of the wire pulling trolley 4, and a frame 41 is installed above the wire pulling trolley 4. The output shaft of the drive motor 13 is connected to the main rotating shaft 11, and the active rotating shaft 11 is located on one side of the upper surface of the frame 41. The slave rotating shaft 12 is located on the other side of the upper surface of the frame 41, and the slave rotating shaft 12 is rotatably connected to the upper surface of the frame 41. The crawler 14 is installed on the sides of the main rotating shaft 11 and the slave rotating shaft 12, wrapping the main rotating shaft 11 and the slave rotating shaft 12. The upper crawler guard plate 15 is installed on the upper surface of the main rotating shaft 11 and the slave rotating shaft 12, and the lower crawler guard plate 16 is installed on the lower surface of the main rotating shaft 11 and the slave rotating shaft 12.

[0057] In this embodiment, Figure 3 、 Figure 4 、 Figure 5 As shown, the fixed-side synchronous belt mechanism 1 and the movable-side synchronous belt mechanism 2 are driven by a crawler 14, which has a large contact area with the wire and traction rope on the pulling trolley 4, and can provide a stable driving force on the wire or traction line, ensuring the reliable and effective operation of the pulling trolley. The driving motor 13 drives the main rotating shaft 11 to rotate, thereby rotating the crawler 14 connecting the main rotating shaft 11 and the slave rotating shaft 12, and then rotating the slave rotating shaft 12, realizing the rotation of the fixed-side synchronous belt mechanism 1 and the movable-side synchronous belt mechanism 2, and the crawler upper guard plate 15 and the crawler lower guard plate 16 provide protection.

[0058] Specifically, the main rotating shaft 11 and the secondary rotating shaft 12 have the same diameter.

[0059] Specifically, the rotation directions of the drive motors 13 of the fixed-side synchronous belt mechanism 1 and the movable-side synchronous belt mechanism 2 are opposite.

[0060] In this embodiment, the rotation directions of the drive motors 13 of the fixed-side synchronous belt mechanism 1 and the movable-side synchronous belt mechanism 2 are opposite, and the two rotate in opposite directions, providing traction in the same direction to the wire or traction rope clamped between the two, causing it to move in one direction.

[0061] Example 2

[0062] On the basis of the above-mentioned embodiment 1, the tracks 14 of the above-mentioned fixed-side synchronous belt mechanism 1 and the movable-side synchronous belt mechanism 2 have a certain length, and a synchronous auxiliary wheel set 17 is installed in the middle position thereof, so that the contact surface between the conductor or traction rope and the track 14 is tightened, ensuring the traction force clamped on the conductor or traction rope, and ensuring its effective advancement.

[0063] Specifically, the fixed-side synchronous belt mechanism 1 and the movable-side synchronous belt mechanism 2 also include a synchronous auxiliary wheel group 17, which includes multiple auxiliary wheels 171. The diameter of the auxiliary wheel 171 is smaller than the diameter of the main rotating shaft 11 and the slave rotating shaft 12. The auxiliary wheel 171 is rotatably connected, and its bottom surface is slidably connected to the upper surface of the track lower guard plate 16, and its upper surface is slidably connected to the lower surface of the track upper guard plate 15.

[0064] Example 3

[0065] On the basis of the above-mentioned embodiments 1 and 2, in order to ensure that the distance between the movable side synchronous belt mechanism 2 and the fixed side synchronous belt mechanism 1 is accurately adjusted according to different wire diameters, embodiment 3 is specially proposed, which determines whether the conductor is effectively clamped by the traction rope through the pressure received by the pressure sensor 5.

[0066] Specifically, it also includes a pressure sensor 5 and a pressure contact plate 6. The pressure contact plate 6 is a T-shaped structure, and the bottom surface is fixedly connected to the surface of the screw slide 335. The pressure sensor 5 is arranged on the upper surface of the wire pulling trolley 4. The setting position of the pressure sensor 5 is on one side of the left and right movement path of the screw slide 335, which coincides with the movement path of the pressure contact plate 6.

[0067] In this embodiment, Figure 6 As shown, the pressure contact plate 6 is a T-shaped structure, and the bottom surface is fixedly connected to the surface of the screw slide 335. Since the setting position of the pressure sensor 5 is on one side of the left and right movement path of the screw slide 335, it coincides with the movement path of the pressure contact plate 6. The contact between the pressure contact plate 6 connected to the moving side synchronous belt mechanism 2 and the pressure sensor 5 is achieved through the movement of the screw slide 335. The pressure value of the pressure sensor 5 is used to judge whether the traction rope or wire on the pulling trolley 4 is in a tight state. The judgment is made by the pressure size in actual use, and the result is accurate and reliable, ensuring the reliable and effective operation of the pulling trolley.

[0068] Specifically, the pressure sensor 5 is arranged on one side of the moving side synchronous belt mechanism 2, and an adjustment hole 42 is provided on the bottom plate of the corresponding pulling trolley 4, and threaded fixing holes 43 are arranged at equal intervals on both sides of the adjustment hole 42. The pressure sensor 5 is installed on the bracket 51, and the bracket 51 is a "J"-shaped structure. Fixing holes 52 are provided on both sides of the bottom end of the bracket 51. The fixing holes 52 are adapted to the size of the threaded fixing holes 43, and bolts are used to pass through the fixing holes 52 to fix the position of the bracket 51 at the corresponding threaded fixing holes 43.

[0069] In this embodiment, Figure 7 、 Figure 8 、 Figure 9As shown, the bracket 51 is a cross-shaped structure, and the position of the sensor 5 is adjusted by fixing the fixing hole 52 on the bottom surface at different positions of the threaded fixing hole 43. As a result, the pressure on the pressure sensor 5 varies according to the position of the pressure contact plate 6 during movement. When a certain pressure condition is met, the wire or traction rope is subjected to effective traction in the moving side synchronous belt mechanism 2 and the fixed side synchronous belt mechanism 1, and moves forward according to the moving direction, thereby ensuring construction quality.

[0070] Example 4

[0071] On the basis of the above-mentioned embodiment 3, in order to make the distance adjustment more accurate, embodiment 4 is proposed.

[0072] Specifically, size scales are provided on both sides of the adjustment hole 42 .

[0073] In this embodiment, size scales are provided on both sides of the adjustment hole 42. The distance of the bracket 51 is adjusted by the size scales on both sides of the adjustment hole 42 according to the diameter of the power line conductor and the traction line, so as to adjust the position of the pressure sensor 5, thereby ensuring that the track 14 of the fixed side synchronous belt mechanism 1 and the movable side synchronous belt mechanism 2 provide sufficient traction force to the conductor or traction line, ensuring that the conductor is deployed, the traction rope is deployed and recovered.

However, the present invention is not limited to the above embodiments. Various changes can be made within the scope of knowledge possessed by ordinary technicians in this field without departing from the purpose of the present invention.
