In addition, features defined as "first" or "second" may explicitly or implicitly include one or more such features, and are used to distinguish between the described features, without distinction of order or importance.

[0031] In the description of this utility model, it should be noted that, unless otherwise expressly specified or limited, the terms "mounted," "connected," and "connected" should be understood in a broad sense. For example, they can refer to fixed connections, detachable connections, or integral connections; mechanical connections, electrical connections; direct connections, indirect connections through an intermediate medium, and internal communication between two components. Those skilled in the art will understand the specific meanings of the above terms in this utility model based on the specific circumstances.

[0032] Below is the accompanying drawings Figures 1 to 5 The technical solution of the utility model is further illustrated through specific implementation methods.

[0033] like Figure 1-5 As shown, a mobile trolley for welding includes a traveling trolley 1, which is installed on an external track. A moving component 4 and a driving component are provided on the traveling trolley 1. The output end of the driving component is provided with a gear 5 that matches the track. The output end of the moving component 4 is connected to the driving component. The moving component 4 drives the driving component to move, and the movement of the driving component drives the gear 5 to move closer to or away from the track.

[0034] This solution drives the movement of the driving component through the setting of the moving component 4, so that the driving component drives the gear 5 to move closer to or away from the track, and the initial position of the gear 5 can be set away from the track, avoiding the interference of the gear 5 when the traveling trolley 1 is installed on the track. Therefore, the traveling trolley 1 can be directly installed on the track without the need for precise alignment of the gear 5 and the rack of the track. After the traveling trolley 1 is installed on the track, the gear 5 can be moved so that the gear 5 engages with the rack on the track.

[0035] It is worth noting that a rack is fixed on the track (not shown in the figure), and the rack is engaged with the gear 5. When the gear 5 rotates, the traveling trolley 1 is driven to move along the track by the cooperation between the gear 5 and the rack.

[0036] like Figure 1 、 2 As shown in Figure 5, it also includes a spacing adjustment component 3. Two sets of clamping wheel groups 2 are provided at the bottom end of the traveling trolley 1. The traveling trolley 1 is clamped on the track by the two sets of clamping wheel groups 2. The spacing adjustment component 3 is used to adjust the spacing between the two sets of clamping wheel groups 2 so that the two sets of clamping wheel groups 2 can loosen or clamp the track.

[0037] The spacing adjustment assembly 3 includes a threaded rod 31 and a guide rail pair 32;

[0038] The movable end of the guide rail pair 32 is connected to one of the clamping wheel sets 2, and the fixed end of the guide rail pair 32 is fixedly mounted on the bottom end of the traveling trolley 1;

[0039] One end of the threaded rod 31 is threadedly inserted into the movable end of the guide rail pair 32, and the other end of the threaded rod 31 passes through the traveling trolley 1 and extends to the outside to be hinged with a locking member 33. A positioning portion 331 is convexly provided on one side of the hinged end of the locking member 33 and the threaded rod 31. The surface of the positioning portion 331 on the side away from the locking member 33 is composed of interconnected planes and arc surfaces. When the locking member 33 is locked, the plane fits tightly against the outer wall of the traveling trolley 1.

[0040] Specifically, the track is clamped by two clamping wheel sets 2. When clamping the track, the clamping wheel sets 2 are in rolling contact with the track, so that the traveling trolley 1 can move stably along the track.

[0041] It is worth noting that by rotating the threaded rod 31 , the movable end of the guide rail pair 32 can be driven to move, thereby adjusting the distance between the two clamping wheel sets 2 to adapt to different models of tracks.

[0042] like Figure 5As shown, a positioning groove 15 is provided on the outer side wall of the traveling trolley 1 , and the positioning portion 331 is located in the positioning groove 15 . When the locking member 33 is locked, the plane fits tightly against the inner side wall of the positioning groove 15 .

[0043] like Figure 2 and 5 As shown, a first spring 34 is connected between the moving end of the guide rail pair 32 and the side wall of the traveling trolley 1 , and the first spring 34 is sleeved on the outside of the threaded rod 31 .

[0044] Specifically, when the trolley 1 needs to be separated from the track, the locking piece 33 is rotated so that the arc surface of the positioning portion 331 contacts the inner wall of the positioning groove 15. Then, under the action of the compressed first spring 34, the first spring 34 pushes the moving end of the guide rail pair 32 to move, and the moving end of the guide rail pair 32 drives the locking piece 33 connected to the threaded rod 31 to move, thereby rotating the locking piece 33 and causing one of the clamping wheel groups 2 to move away from the track until one of the clamping wheel groups 2 is reset. At this time, the two clamping wheel groups 2 no longer clamp the track, and the trolley 1 can be separated from the track.

[0045] It is worth noting that under the action of the first spring 34, when the locking member 33 is locked, the plane of the positioning portion 331 is always close to the inner wall of the positioning groove 15. At this time, the locking member 33 cannot rotate without the action of external force, so that the two clamping wheel groups 2 can stably clamp the track. When the clamping wheel group 2 needs to be no longer clamped on the track, the user only needs to slightly rotate the locking member 33 so that the arc surface of the positioning portion 331 contacts the inner wall of the positioning groove 15. The locking member 33 can be automatically driven to rotate under the action of the first spring 34, so that the clamping wheel group 2 is no longer clamped on the track. The operation is simple and quick.

[0046] Furthermore, in order to avoid interference between the gear 5 and the track when the traveling trolley 1 is separated from the track, the gear 5 can be driven away from the track by the moving component 4 so that the gear 5 is separated from the rack of the track.

[0047] like Figure 2 As shown, one end of the locking member 33 away from the threaded rod 31 is connected to the adsorption member 11 , and the adsorption member 11 is fixedly mounted on the outer side wall of the traveling trolley 1 .

[0048] Further, such as Figure 5 As shown, the adsorption member 11 is a magnet, and an adsorption portion 332 is protruded from the side wall of the locking member 33 at one end away from the threaded rod 31 , and the adsorption portion 332 is magnetically connected to the magnet.

[0049] Specifically, the adsorption member 11 is a magnet, which can facilitate the connection and separation of the locking member 33 and the adsorption member 11. The adsorption member 11 is set to fix the locking member 33 when the locking member 33 is locked, preventing the locking member 33 from rotating, thereby improving the stability of the device during operation.

[0050] It is worth noting that the positioning groove 15 can facilitate the rotation of the locking member 33 toward the adsorption member 11 , so that the adsorption portion 332 and the adsorption member 11 can be precisely docked.

[0051] like Figure 2 As shown, a first spring 34 is connected between the moving end of the guide rail pair 32 and the side wall of the traveling trolley 1 , and the first spring 34 is sleeved on the outside of the threaded rod 31 .

[0052] Specifically, by setting the first spring 34, when the locking member 33 is separated from the adsorption member 11, the first spring 34 drives the moving end of the guide rail pair 32 to move so that one of the clamping wheel groups 2 is reset, thereby automatically making the two clamping wheel groups 2 no longer clamp the track, and when not in use, the spacing between the two clamping wheel groups 2 is greater than the spacing between the tracks, and the user no longer needs to adjust the spacing between the two clamping wheel groups 2, thereby facilitating the installation of the walking trolley 1 on the track.

[0053] like Figure 2-3 As shown, the driving assembly includes a reducer 52, a groove 12 is provided at the top of the walking trolley 1, the reducer 52 is arranged in the groove 12, and a first through hole 121 is provided on the inner bottom wall of the groove 12. A transmission shaft 51 is installed at the output end of the reducer 52, and the diameter of the first through hole 121 is larger than the diameter of the transmission shaft 51. The transmission shaft 51 passes through the first through hole 121 and is coaxially connected to the gear 5.

[0054] Specifically, the gear 5 coaxially connected to the transmission shaft 51 is driven to rotate by the reducer 52, and the traveling trolley 1 is driven to move along the track under the action of the engagement between the gear 5 and the rack of the track.

[0055] Furthermore, the diameter of the first through hole 121 is larger than the diameter of the transmission shaft 51 , allowing the transmission shaft 51 to move within the first through hole 121 , thereby adjusting the position of the gear 5 through the moving component 4 .

[0056] like Figure 3-4 As shown, the moving assembly 4 includes a carrier 41, one end of which is rotatably mounted in the groove 12, and the reducer 52 is mounted on the top of the carrier 41. A second through hole 411 is formed on the carrier 41, and the diameter of the second through hole 411 is larger than the diameter of the transmission shaft 51. The transmission shaft 51 passes through the second through hole 411 and the first through hole 121 in sequence;

[0057] The other end of the carrier 41 is connected to a fixing rod 42, and the side wall of the walking trolley 1 is provided with a sliding hole 13 connected to the interior of the groove 12. The side wall of the walking trolley 1 is also provided with two positioning holes 14, and the two positioning holes 14 are connected through the sliding hole 13. One end of the fixing rod 42 passes through the sliding hole 13 and one of the positioning holes 14 and extends to the outside of the walking trolley 1, and one end of the fixing rod 42 is movably sleeved on the outside of the positioning sleeve 43, and the positioning sleeve 43 is movably inserted into one of the positioning holes 14.

[0058] Specifically, when the gear 5 needs to be away from the track, the positioning sleeve 43 is removed from one of the positioning holes 14, and then the fixing rod 42 is moved along the sliding hole 13, so that the fixing rod 42 moves from one of the positioning holes 14 to the other positioning hole 14. When moving the fixing rod 42, the fixing rod 42 drives the carrier 41 to rotate, and the carrier 41 drives the reducer 52 to rotate, thereby driving the transmission shaft 51 to move in the second through hole 411 and the first through hole 121, and the transmission shaft 51 drives the gear 5 away from the track. When the fixing rod 42 moves to the other positioning hole 14, the positioning sleeve 43 is moved so that the positioning sleeve 43 moves into the other positioning hole 14, thereby fixing the fixing rod 42 in the other fixing hole 14, so that the gear 5 is always away from the track, which is convenient for the user to operate when disassembling and assembling the walking trolley 1 and the track, making disassembly and assembly faster.

[0059] like Figure 4 As shown, one end of the fixing rod 42 is connected to a stopper 421 , the end of the positioning sleeve 43 is provided with a T-shaped hole 431 , a second spring 422 is connected between the stopper 421 and the T-shaped hole 431 , and the second spring 422 is sleeved on the outside of the fixing rod 42 .

[0060] Specifically, when the positioning sleeve 43 is inserted into the positioning hole 14 , the positioning sleeve 43 can be stably fixed in the positioning hole 14 through the second spring 422 between the stopper 421 and the T-shaped hole 431 .

[0061] like Figure 1 As shown, a cover plate is provided on the top of the traveling trolley 1 , and the cover plate is used to cover the groove 12 .

[0062] Specifically, the groove 12 is shielded by the provided cover plate, thereby protecting the driving component in the groove 12 .

[0063] The technical principles of the present invention have been described above with reference to specific embodiments. These descriptions are intended solely to illustrate the principles of the present invention and should not be construed in any way as limiting the scope of protection of the present invention. Based on the explanations herein, those skilled in the art will be able to devise other specific implementations of the present invention without inventive effort, and such implementations will fall within the scope of protection of the present invention.
