Description

TECHNICAL FIELD

[0001] The utility model relates to the technical field of welding, especially to a walking clutch adjusting mechanism and a welding trolley that can be matched with various curvature tracks. BACKGROUND

[0002] The rapid development of the domestic nuclear power construction industry leads to an increasing demand for various new and advanced welding technologies. Compared with traditional automobile ships, aerospace and other fields, although the application range of automatic welding has initially taken shape, but due to the use in prefabrication plants or production workshops, the nuclear power construction industry mainly uses in the nuclear island, so the automatic welding requires higher, and the carrying and installation need to be more convenient.

[0003] With the development of domestic automatic welding technology, domestic equipment has been gradually improved in terms of technical advancement, stability and reliability, but there are still great deficiencies. In the process of nuclear power site welding construction, a large number of track type welding trolleys are needed, and the existing automatic welding trolleys usually do not have a manual clutch device. When the trolley needs to be quickly moved to the other side after welding, the trolley needs to be directly disassembled and installed at another place, or the trolley speed needs to be increased to quickly reset the trolley, but the motor speed has an upper limit value, and it is impossible to infinitely increase the walking speed. Disassembling and reinstalling the trolley will increase the workload of welders, which is not conducive to the operation of the trolley.

[0004] At the same time, there are various sizes of pipes in the nuclear island, and the welding track needs to be frequently replaced to adapt to the welding of pipes of different sizes. However, due to the different curvatures of welding tracks of different specifications, the original driving mechanism cannot better adapt to the replaced welding track, and the height of the driving mechanism needs to be adjusted to ensure the stability of the transmission. The existing track type automatic welding trolley usually changes the connecting piece of the driving mechanism to achieve this effect, which further increases the workload of the site operators and prolongs the installation time, reducing the site construction efficiency.

[0047] Example

[0048] Reference Figures 1-5 This utility model provides a walking clutch adjustment mechanism, including a walking motor bracket 100, a drive motor assembly 200, and a manual clutch device 400;

[0049] The walking motor bracket 100 is used to connect with the welding trolley. The walking motor bracket 100 includes a first side plate 101 and a second side plate 102. The drive motor assembly 200 is disposed between the first side plate 101 and the second side plate 102.

[0050] Guide sliders 500 are provided on the side of the first side plate 101 and the second side plate 102 facing the drive motor assembly 200; guide rails 600 matching the guide sliders 500 are provided on the drive motor assembly 200.

[0051] An elongated hole 1011 is provided on the first side plate 101, and the elongated hole 1011 extends along a first direction; the manual clutch device 400 includes a limiting plug bolt 401, the limiting plug bolt 401 passes through the elongated hole 1011 and is connected to the drive motor assembly 200; the manual clutch device 400 is used to make the drive motor assembly 200 move up and down along the first direction.

[0052] The first direction is the length direction of the guide rail 600.

[0053] In some embodiments, the walking motor bracket 100 has a first side plate 101 and a second side plate 102 disposed opposite to each other, and a drive motor assembly 200 is disposed between the first side plate 101 and the second side plate 102; a guide slider 500 is provided on both the first side plate 101 and the second side plate 102, and a guide rail 600 is provided on the drive motor assembly 200; the guide rail 600 and the guide slider 500 cooperate to enable the drive motor assembly 200 to be raised and lowered precisely.

[0054] An elongated hole 1011 is provided on the first side plate 101, the length of which is not less than the lifting range of the drive motor assembly 200. The limit plug bolt 401 of the manual clutch device 400 passes through the elongated hole 1011 and is connected to the drive motor assembly 200. By operating the manual clutch device 400, the drive motor assembly 200 is raised or lowered relative to the travel motor bracket 100, thereby enabling the drive motor assembly 200 to engage or disengage with the gear ring on the welding track. When the welding carriage needs to move quickly on the welding track, the manual clutch device 400 disengages the drive motor assembly 200 from the welding track, allowing the welding carriage to move quickly on the welding track, improving the walking efficiency of the welding carriage and accelerating the reset of the welding carriage.

[0055] Reference Figure 3 and Figure 4 In an optional embodiment, the manual clutch device 400 includes a spindle sleeve 403 and a spindle 402, the spindle 402 being screwed into the spindle sleeve 403, and both the upper and lower ends of the spindle 402 extending out of the spindle sleeve 403.

[0056] A fixing sleeve 300 is provided on the first side plate 101, and the mandrel sleeve 403 passes through the fixing sleeve 300; a guide rail 301 is spirally provided on the fixing sleeve 300, and a limiting pin is provided on the mandrel sleeve 403, and the limiting pin is assembled in the guide rail 301.

[0057] In some embodiments, the fixing sleeve 300 is fixed to the first side plate 101, that is, the fixing sleeve 300 is fixed to the first side plate 101 and cannot move; the mandrel sleeve 403 is inserted into the fixing sleeve 300, and a guide rail 301 is provided on the side wall of the fixing sleeve 300. The limiting pin provided on the mandrel sleeve 403 is assembled in the guide rail 301; the limiting pin and the guide rail 301 cooperate to limit the lifting range of the mandrel sleeve 403; an upper groove is provided at the lowermost end of the guide rail 301. When the mandrel sleeve 403 is subjected to an upward force, the mandrel sleeve 403 moves into the upper groove. The upper groove prevents the mandrel sleeve 403 from moving along the guide rail 301. This ensures that under normal use, the drive motor assembly 200 and the traveling displacement gear 204 on the welding rail remain engaged.

[0058] When the mandrel sleeve 403 rotates 180°, the drive motor assembly 200 can be raised by 8mm, which separates the travel displacement gear 204 from the welded track gear ring, effectively reducing the overall height required for the equipment.

[0059] In an optional embodiment, a clutch handle 404 is provided at the upper end of the mandrel sleeve 403, and an adjustment knob 405 is sleeved at the upper end of the mandrel 402; a locking bolt 406 is provided at the upper end of the adjustment knob 405, and the locking bolt 406 passes through the adjustment knob and is screwed to the upper end of the mandrel 402.

[0060] In some embodiments, a clutch handle 404 is fixedly provided at the upper end of the mandrel sleeve 403, and an adjustment knob 405 is provided on the mandrel 402. The adjustment knob 405 is sleeved on the mandrel 402 and rotates synchronously with the mandrel 402.

[0061] The spindle 402 is screwed to the spindle sleeve 403. In order to prevent the spindle 402 from rotating relative to the spindle sleeve 403, a locking bolt 406 is screwed onto the spindle 402. The nut of the locking bolt 406 is located at the upper end of the adjustment rotation. The nut of the locking bolt 406 can apply pressure to the adjustment knob 405, so that the adjustment knob 405 and the clutch handle 404 are kept in contact. This ensures that the spindle 402 will not rotate, that is, the spindle 402 and the spindle sleeve 403 remain fixed during use.

[0062] In an optional embodiment, a lower stop 4011 is provided at the lower end of the mandrel 402, and the lower stop 4011 is connected to the limiting plug bolt 401.

[0063] A movable plate 4021 is provided at the lower end of the mandrel 402, and a movable cavity 40111 is provided inside the lower stop block 4011, with the movable plate 4021 located inside the movable cavity 40111.

[0064] A lower positioning groove is provided on the upper end face of the lower stop block 4011; an upper positioning groove is provided on one end of the mandrel sleeve 403 facing the lower stop block 4011.

[0065] A buffer spring 409 is sleeved on the spindle 402. One end of the buffer spring 409 is located in the upper positioning groove, and the other end is located in the lower positioning groove. The buffer spring 409 causes the lower stop block 4011 to have a tendency to move away from the spindle 402.

[0066] In some embodiments, a lower stop 4011 is provided at the lower end of the spindle 402, and the lower stop 4011 is connected to the limiting plug bolt 401. The movable plate 4021 provided at the lower end of the spindle 402 is located in the movable cavity 40111 of the lower stop 4011. One end of the buffer spring 409 abuts against the upper positioning groove on the spindle sleeve 403, and the other end abuts against the lower positioning groove of the lower stop 4011. The buffer spring 409 is in a compressed state, and the buffer spring 409 makes the lower stop 4011 always have a tendency to move away from the spindle 402.

[0067] In this way, the lower stop 4011 has a certain buffer in the axial direction of the spindle 402, and the buffer spring 409 can compensate for the transmission gap between the traveling displacement gear 204 and the gear ring of the welding track caused by machining or welding track deformation.

[0068] In an optional embodiment, the mandrel 402 is provided with a guide protrusion 408, and the guide protrusion 408 is located inside the mandrel sleeve 403;

[0069] A limiting screw 407 is provided inside the mandrel sleeve 403, and the limiting screw 407 is located at the upper end of the guide protrusion 408; the limiting screw 407 cooperates with the guide protrusion 408 to limit the range of upward movement of the mandrel 402.

[0070] In some embodiments, the travel clutch adjustment mechanism can be adapted to various types of welding rails. By loosening the locking bolt 406 and then rotating it, the mandrel 402 and the mandrel sleeve 403 can rotate relative to each other, allowing the mandrel 402 to rise and fall. This, in turn, causes the mandrel 402 to move the limit plug bolt 401 up and down, thereby adjusting the height of the drive motor assembly 200. This allows the travel shift gear 204 of the drive motor assembly 200 to mesh with the gear rings of welding rails of different specifications, greatly improving on-site construction efficiency and welding quality.

[0071] To further achieve rapid adjustment, a limiting set screw 407 is provided inside the mandrel sleeve 403, and a guide protrusion 408 is provided on the mandrel 402. The guide protrusion 408 matches the mandrel sleeve 403, enabling more precise relative movement between the mandrel 402 and the mandrel sleeve 403. The guide protrusion 408 can also collide with the limiting set screw 407, which restricts the upward movement range of the mandrel 402. When the limiting set screw 407 collides with the guide protrusion 408, the travel displacement gear 204 of the drive motor assembly 200 meshes with the gear ring of the standard welding track, thus enabling adjustment according to the specifications of the actual welding track and improving adjustment efficiency.

[0072] A mark is provided on the clutch handle 404. By rotating the adjustment knob 405, the indicator on the adjustment knob is made to point to the gear mark on the clutch handle 404, thereby quickly adjusting the position of the drive motor assembly 200 according to the specifications of the welding rail. The adjustment method is quantified, which facilitates on-site operation and improves work efficiency.

[0073] Reference Figure 5 In an optional embodiment, the drive motor assembly 200 further includes a first drive motor 201, a transmission worm gear 202, a transmission worm wheel 203, and a travel displacement gear 204.

[0074] One end of the transmission worm 202 is connected to the first drive motor 201. The transmission worm wheel 203 and the travel shift gear 204 are coaxially arranged and rotate synchronously. The transmission worm wheel 203 is connected to the transmission worm 202.

[0075] The traveling shift gear 204 is used to mesh with the gear ring of the welding track.

[0076] In some embodiments, a motor wiring port is provided on the first drive motor 201 to facilitate after-sales maintenance and customer-customized modifications; the first drive motor 201 causes the transmission worm gear 202 to rotate, the transmission worm gear 202 causes the transmission worm wheel 203 to rotate, and the transmission worm wheel 203 drives the walking displacement gear 204 to rotate synchronously; this driving method can achieve precise control of welding speed while reducing space size.

[0077] The manual clutch device 400 of the walking clutch adjustment mechanism provided by this utility model has a limit plug bolt 401 connected to the drive motor assembly 200. When it is necessary to separate the drive motor assembly 200 from the welding track, the manual clutch device 400 drives the drive motor assembly 200 to move upward, thus separating the drive motor assembly 200 from the welding track. After the drive motor assembly 200 is separated from the welding track, the welding carriage can move quickly on the welding track, realizing the rapid reset of the welding carriage and thus improving work efficiency.

[0078] Reference Figure 6 , Figure 7 and Figure 8 This utility model provides a welding trolley that can be matched with various curvature tracks, including a welding trolley body 700 and a walking clutch adjustment mechanism as described in any of the aforementioned embodiments.

[0079] In an optional embodiment, the welding carriage body 700 is provided with a drive hole, the walking motor bracket 100 is disposed on the upper end surface of the welding carriage body 700, and the drive motor assembly 200 is assembled in the drive hole.

[0080] In some embodiments, the walking motor bracket 100 is detachably fixed to the welding carriage body 700. Generally, the walking motor bracket 100 is fixed to the welding carriage body 700 by bolts. After loosening the connecting bolts, the walking clutch adjustment mechanism can be disassembled, which facilitates after-sales replacement during use and also facilitates modification to meet the customized needs of customers.

[0081] In an optional embodiment, a first wheel assembly 800 and a second wheel assembly 900 are provided on the lower end surface of the welding trolley body 700, and the drive motor assembly 200 is disposed between the first wheel assembly and the second wheel assembly 900; the first wheel assembly and the second wheel assembly 900 can cooperate to clamp on the welding track.

[0082] The first wheel assembly includes two first wheels. Each first wheel includes a first wheel frame 801, an assembly shaft 803, and a wheel body 802. The wheel body 802 is disposed on the assembly shaft 803, and the assembly shaft 803 is rotatably mounted on the first wheel frame 801. A fixing hole 804 is provided on the first wheel frame 801, and a fixing screw is installed in the fixing hole 804. The fixing screw abuts against the assembly shaft 803.

[0083] In some embodiments, a first wheel assembly 800 and a second wheel assembly 900 are provided on the lower end face of the welding carriage body 700. The first wheel assembly is fixedly mounted on the welding carriage body 700, and the second wheel assembly 900 can move relative to the first wheel assembly. In this way, the first wheel assembly and the second wheel assembly 900 clamp the welding track and facilitate the detachment of the welding carriage from the welding track.

[0084] In order to enable the first wheel assembly to match welding rails of multiple specifications, the wheel body 802 of the first wheel assembly is provided with an assembly shaft 803, which is rotatably mounted on the first wheel frame 801; the wheel body 802 can be inserted into the rail grooves on both sides of the welding rail, and the assembly shaft 803 is rotated to a suitable position; the fixing screw is rotated to make the fixing screw abut against the assembly shaft 803, thereby preventing the assembly shaft 803 from rotating and fixing the position of the wheel body 802.

[0085] To make the assembly shaft 803 more securely fixed to the first wheel frame 801, a number of fixing holes 804 are provided on the first wheel frame 801.

[0086] In an optional embodiment, the second wheel assembly 900 includes a sliding frame 903 and two second wheels. The second wheel includes a lower guide rail 901, an upper slider 902, and a second wheel frame 907. The lower guide rail 901 is disposed on the welding trolley body 700, and the upper slider 902 is slidably disposed on the lower guide rail 901.

[0087] The two ends of the sliding frame 903 are respectively connected to a second wheel frame 907. An adjusting shaft 904 is hinged on the sliding frame 903. One end of the adjusting shaft 904 is connected to an opening and closing handle 905. The opening and closing handle 905 is rotatably mounted on the welding trolley body 700. The opening and closing handle 905 is used to drive the sliding frame 903 to move towards the first wheel assembly.

[0088] A fixing pin 906 is provided on the opening and closing handle 905. The fixing pin 906 is used to connect with the first wheel frame 801 of the second wheel to fix the opening and closing handle 905.

[0089] The second wheel assembly 900 moves toward the first wheel assembly, and when the welding carriage needs to be disengaged from the welding guide rail, the second wheel assembly 900 moves away from the first wheel assembly.

[0090] The lower guide rail 901 of the second wheel of the second wheel assembly 900 is used to guide the upper slider 902 toward or away from the first wheel assembly; a second wheel frame 907 is provided on the upper slider 902.

[0091] In order for the second wheel assembly 900 to cooperate with the first wheel assembly to clamp the welding rail, the sliding frame 903 is provided with an opening and closing handle 905. One end of the opening and closing handle 905 is connected to the sliding frame 903, and the other end is provided with a fixing pin 906.

[0092] By rotating the opening and closing handle 905, the sliding frame 903 can be moved toward or away from the first wheel assembly; when the second wheel assembly 900 needs to be kept fixed, the fixing pin 906 on the opening and closing handle 905 is connected to the second wheel frame 907, thereby fixing the position of the opening and closing handle 905, so that the second wheel assembly 900 is kept in contact with the welding track.

[0093] In some embodiments, the fixing pin 906 is mounted on the second wheel frame 907, and a fixing hole is provided on the opening and closing handle 905. When the fixing pin 906 can pass through the fixing hole in one state and cannot pass through the fixing hole in another state, when the opening and closing handle 905 is fixed as needed, after the fixing pin 906 passes through the fixing hole, the fixing pin 906 is rotated so that the fixing pin 906 cannot pass through the fixing hole. This limits the movement of the opening and closing handle 905 and prevents the accompanying cable from accidentally opening the opening and closing handle 905 during the welding process, which could cause the welding carriage to fall off or other risks.

[0094] The adjusting shaft 904 on the sliding frame 903 is a bolt and nut structure.
