When welding the left and right side panels of the dump truck compartment, auxiliary support mechanisms are needed to assist in supporting the side panels and reinforcing ribs, so as to facilitate the later stable welding of the compartment side panels. The patent name disclosed in the prior art with the announcement number "CN221231868U" is "an auxiliary device for welding a car bottom plate", which discloses a clamping structure including a group of mounting plates installed in the middle of the connecting plate, a fixing block 1 connected to the top of the mounting plate, a torsion rod running through the fixing block 1 and the mounting plate, and fixing blocks 2 arranged at both ends of the torsion rod. The telescopic plate is connected to the fixing plate below by bolts, a protrusion is arranged at the top of the weight rod, and a groove is arranged at a corresponding position inside the fixing plate. The bottom plate 1 and the bottom plate 2 are placed between the connecting plates. After placement, the upper weight rod is manually pulled downward, and the lower weight rod is extended upward. After the position is set, the weight rod is twisted, and the protrusion on the rod is engaged with the groove inside the fixing plate to fix the position, and the two weight rods are pressed against each other to press the bottom plate 1, the bottom plate 2 and the car plate tightly together for easy welding. The patent name disclosed in the prior art with the announcement number "CN113500334A" is "A large electric drive mine car cabin floor welding auxiliary device", which discloses the use of a hoist to lift the cabin floor of a large electric drive mining dump truck to the top of a welding platform, install a bead-type positioning seat at the positioning point of the welding platform directly opposite the arc surface of the cabin floor, install the connector on the welding platform at the positioning point of the arc surface of the cabin floor, the cabin floor is lowered, and the circular body of the bead-type positioning seat contacts the arc surface of the cabin floor to realize the positioning of the cabin floor and the welding platform, place the cabin floor on the welding platform, and the adjusting device is installed between the support frame and the base.

The extrusion block squeezes the air storage bag, so that the gas in the air storage bag enters the air storage cavity through the connecting pipe, thereby causing the self-propelled protective plate in the air storage cavity to move upward and exert a thrust on the upper surface of the bottom auxiliary support plate, thereby increasing the supporting force on the upper surface of the bottom auxiliary support plate and avoiding welding stress that causes the upper surface of the bottom auxiliary support plate and the side panel of the car body to be concave and deformed.

[0017] When the pressure sensor in the deformation monitoring component detects a certain pressure value, it means that the car side panel and the reinforcing rib plate are sunken and the extrusion frame moves downward. At this time, the pressure sensor can transmit this signal to the central processing module installed on the side of the bottom auxiliary support plate. The central processing module can control the alarm to sound an alarm to remind the staff to handle it.

[0022] See also Figure 1-Figure 11 , the present invention provides the following technical solutions: Embodiment 1: The auxiliary support mechanism for welding the carriage of a mining dump truck in this embodiment can improve the overall auxiliary support strength and the stability of the support fixation, and avoid the welding stress causing the upper surface of the bottom auxiliary support plate 2 and the carriage side plate 14 to be concave and deformed. For the specific structure, refer to the attached Figure 1-Figure 5As shown, it includes an auxiliary folding plate 1, and the interior of the front and rear sides of the auxiliary folding plate 1 are both installed with a bottom auxiliary support plate 2 in an "L" shape structure through a folding storage mechanism; the upper surface of the auxiliary folding plate 1 and the upper surface of the horizontal surface of the bottom auxiliary support plate 2 are placed with a car body side panel 14, and the car body side panel 14 is placed with a reinforcing rib 141; the upper surface of the horizontal surface of the bottom auxiliary support plate 2 is connected with a side auxiliary support plate 3; the interior of the vertical surface of the bottom auxiliary support plate 2 is connected to the adjustment plate 4 through an electric push rod 8, and extrusion blocks 5 are installed at equal intervals below the adjustment plate 4; a connecting plate 6 is installed on the inner side of the extrusion block 5, and a self-aligning extrusion mechanism 7 for fixing the reinforcing rib 141 is fixed below the connecting plate 6; a deformation monitoring component is installed on the inner side of the self-aligning extrusion mechanism 7; the horizontal surface of the bottom auxiliary support plate 2 is installed with a self-pushing protective plate 11 for increasing the supporting force.

[0023] A moving block 301 is installed on the bottom surface of the side auxiliary support plate 3, and the bottom of the moving block 301 passes through the groove opened in the bottom auxiliary support plate 2. The bottom surface groove of the bottom auxiliary support plate 2 on the rear side of the auxiliary folding plate 1 is symmetrically installed with two first connecting threaded rods 9, and the rear end of the first connecting threaded rod 9 passes through the rear side surface of the rear bottom auxiliary support plate 2. The bottom surface groove of the bottom auxiliary support plate 2 on the front side of the auxiliary folding plate 1 is symmetrically installed with two second connecting threaded rods 10. The outer sides of the second connecting threaded rod 10 and the first connecting threaded rod 9 are both threadedly connected with the moving block 301, and the thread direction of the outer side of the second connecting threaded rod 10 is opposite to the thread direction of the outer side of the first connecting threaded rod 9.

[0024] A docking groove 91 is provided inside one end of the first connecting threaded rod 9 close to the second connecting threaded rod 10, and a docking block 1001 is installed on the outer side of one end of the second connecting threaded rod 10 close to the first connecting threaded rod 9. The docking block 1001 and the docking groove 91 are both arranged in a rectangular shape, and the docking block 1001 and the docking groove 91 are arranged in a concave-convex manner. The first connecting threaded rod 9 and the second connecting threaded rod 10 are used in combination to drive the two side auxiliary support plates 3 to move toward each other, and an air storage airbag 13 is installed in a groove inside the vertical surface of the bottom auxiliary support plate 2, and a connecting pipe 131 with an "L"-shaped structure is installed below the air storage airbag 13, and an air storage cavity 12 is provided inside the horizontal surface of the bottom auxiliary support plate 2, and a self-propelled protective plate 11 is fitted in the air storage cavity 12, and the lower surface of the self-propelled protective plate 11 is connected to the interior of the bottom auxiliary support plate 2 through a reset spring 111, and the end of the connecting pipe 131 away from the air storage airbag 13 passes through the bottom auxiliary support plate 2 and is inserted into the air storage cavity 12.

[0025] First, move the entire auxiliary support mechanism into the working area. After reaching the working area, place the car side panel 14 on the upper surface of the auxiliary folding plate 1 and the two bottom auxiliary support plates 2. Manually rotate the rear ends of the two first connecting threaded rods 9. When the first connecting threaded rod 9 rotates, the second connecting threaded rod 10 is driven to rotate through the concave-convex cooperation between the docking groove 91 and the docking block 1001. When the first connecting threaded rod 9 and the second connecting threaded rod 10 rotate, the outer threaded movable block 301 is driven to move inward by the rotation. At this time, the movable block 301 drives the upper side auxiliary support plate 3 to move inward, so that the two groups of side auxiliary support plates 3 squeeze and fix the front and rear sides of the car side panel 14.

[0026] Next, the reinforcing rib 141 is placed on the car side panel 14, and then the reinforcing rib 141 is moved so that the reinforcing rib 141 is below the self-aligning extrusion mechanism 7 at the corresponding position, and then the electric push rod 8 is started, and the output end of the electric push rod 8 drives the adjustment plate 4 to move downward, and the adjustment plate 4 drives the extrusion block 5 and the connecting plate 6 to move downward, and at this time the connecting plate 6 drives the self-aligning extrusion mechanism 7 to move downward, and since the left and right sides of the self-aligning extrusion mechanism 7 are both inclined, the self-aligning extrusion mechanism 7 can apply an inward extrusion force to the left and right sides of the reinforcing rib 141, so that the reinforcing rib 141 can be automatically corrected to avoid the inclined placement of the reinforcing rib 141, so that the reinforcing rib 141 is placed vertically with the front and rear sides of the car side panel 14, and at the same time, the self-aligning extrusion mechanism 7 can apply a downward pressure to the reinforcing rib 141, so as to facilitate the car side panel 1 4 is clamped and fixed, and at the same time, the extrusion block 5 can squeeze the air storage bag 13 when it moves downward, so that the gas in the air storage bag 13 enters the air storage cavity 12 at the corresponding position through the connecting pipe 131. At this time, the self-propelled protective plate 11 in the air storage cavity 12 automatically moves upward, so that the self-propelled protective plate 11 applies an upward supporting force to the upper surface of the auxiliary folding plate 1, and then welding work can be carried out. If a relatively high-power welding equipment is used for welding, due to the large welding current, a large welding stress may be generated. At this time, the cooperation of the self-propelled protective plate 11 and the self-aligning extrusion mechanism 7 can well resist these stresses, avoid the welding stress and cause the upper surface of the bottom auxiliary support plate 2 and the car body side plate 14 to be concave and deformed, so that the entire auxiliary support mechanism can well support the car body side plate 14 and the reinforcing rib plate 141, so as to facilitate welding operations.

[0027] Embodiment 2: The auxiliary support mechanism for welding the mining dump truck compartment in this embodiment can monitor the concave deformation on the basis of embodiment 1, so as to facilitate timely discovery at a later stage. For the specific structure, refer to the attached Figure 6-Figure 7As shown, the deformation monitoring component includes an extrusion frame 71 installed on the inner side below the self-aligning extrusion mechanism 7, a lifting control column 72 is fixed on the upper middle part of the extrusion frame 71, and the upper part of the lifting control column 72 is inserted into the groove opened in the self-aligning extrusion mechanism 7; a connecting spring 73 is installed inside the upper part of the groove opened in the self-aligning extrusion mechanism 7, and a lifting control column 72 is installed below the connecting spring 73; a cross bar 75 is fixed inside the lower part of the groove opened in the self-aligning extrusion mechanism 7; a through slot 74 is opened inside the lifting control column 72, and a cross bar 75 is arranged through the inside of the through slot 74; a pressure sensor 76 is installed inside the upper part of the through slot 74, and a cross bar 75 is arranged below the pressure sensor 76, the left and right sides of the self-aligning extrusion mechanism 7 and the extrusion frame 71 are arranged in an inclined shape, and the middle parts of the self-aligning extrusion mechanism 7 and the extrusion frame 71 are arranged in a horizontal shape; the extrusion frame 71 and the self-aligning extrusion mechanism 7 constitute a lifting structure.

[0028] When the self-aligning extrusion mechanism 7 moves downward, it will drive the extrusion frame 71 to move downward together. When the extrusion frame 71 drops to contact the reinforcing rib 141, the self-aligning extrusion mechanism 7 continues to move downward, which will cause the lifting control column 72 above the extrusion frame 71 to move upward. At this time, the connecting spring 73 is squeezed and stored. When the bottom auxiliary support plate 2 and the car side plate 14 are partially depressed downward due to welding stress, the car side plate 14 drives the reinforcing rib 141 to move downward. At this time, the storage force of the connecting spring 73 will drive the extrusion frame 71 and the lifting control column 72 to move upward. The control column 72 moves downward together. At this time, the cross bar 75 will apply a pressure to the pressure sensor 76 in the lifting control column 72. When the pressure sensor 76 detects a certain pressure value, it means that the car side panel 14 and the reinforcing rib 141 are recessed downward, causing the extrusion frame 71 to move downward. At this time, the pressure sensor 76 transmits this signal to the central processing module installed on the side of the bottom auxiliary support plate 2. The central processing module can control the alarm installed on the side of the bottom auxiliary support plate 2 to sound an alarm, and then the staff can hear the alarm and rush to stop the welding work in time.

[0029] Embodiment 3: The auxiliary support mechanism for welding the carriage of a mining dump truck in this embodiment can be folded in half and stored when not in use, which can reduce the occupied area of ​​the entire auxiliary support mechanism and facilitate the subsequent carrying and transportation operations. For the specific structure, refer to the attached Figure 8 -Attached Fig.11 As shown, the folding storage mechanism includes two rotating rods 102 installed in the auxiliary folding plate 1. The auxiliary folding plate 1 is arranged in an inverted "U" shape. The inner walls on the left and right sides of the auxiliary folding plate 1 are symmetrically provided with two groups of limiting slide grooves 101. The left and right ends of the rotating rod 102 are inserted into the limiting slide grooves 101. A rotating block 103 is installed on the outer side of the rotating rod 102. The outer side of the rotating block 103 is connected to one side of the bottom auxiliary support plate 2.

[0030] On the basis of Example 1, when the entire auxiliary support mechanism is used up and needs to be moved or transported, the staff manually pulls the two bottom auxiliary support plates 2 outward, and the two bottom auxiliary support plates 2 drive the rotating blocks 103 and the rotating rods 102 at the corresponding positions to move outward. At this time, the rotating rods 102 slide in the limiting slide grooves 101, and at the same time, the first connecting threaded rod 9 under the bottom auxiliary support plate 2 on the rear side of the auxiliary folding plate 1 is separated from the second connecting threaded rod 10 under the bottom auxiliary support plate 2 on the front side of the auxiliary folding plate 1. At this time, the docking block 1001 is separated from the docking groove 91, and then the two bottom auxiliary support plates 2 are manually rotated. At this time, the two bottom auxiliary support plates 2 and the rotating block 103 rotate with the rotating rod 102 as the center. At this time, the two bottom auxiliary support plates 2 are placed vertically, thereby reducing the overall occupied area of ​​the entire auxiliary support mechanism, which is convenient for carrying and transporting the auxiliary support mechanism.

[0031] Although the present invention has been described in detail with reference to the aforementioned embodiments, it is still possible for those skilled in the art to modify the technical solutions described in the aforementioned embodiments, or to make equivalent substitutions for some of the technical features therein. Any modifications, equivalent substitutions, improvements, etc. made within the spirit and principles of the present invention should be included in the protection scope of the present invention.
