[0002] A chemical reagent transport vehicle is a vehicle specially used to transport chemical reagents. It usually has a special structure and design to ensure the safety and stability of chemical reagents during transportation. However, in some special cases, chemical reagent transport vehicles need to be specially modified after leaving the factory before they can be used. The modification process generally involves welding work on the transport vehicle. The body of the transport vehicle itself is relatively tall, and the workers can only perform welding work by climbing ladders, etc., which makes the entire welding process very inconvenient. Summary of the invention

[0008] By adopting the above scheme, during the process of transport vehicle modification, the staff selects a suitable operating table according to the welding position on the transport vehicle, and then stands on the operating table. Then, the driving component 1 and the driving component 2 respectively adjust the horizontal position and the vertical height of the operating table so that the operating table can adapt to the position of the welding point, thereby facilitating people's modification welding of the transport vehicle. After one welding point is completed, the staff can quickly adjust to the next welding position through the driving component 1 and the driving component 2, making the entire welding process more convenient and quick.

[0014] By adopting the above solution, the motor drives gear 1 and gear 2 to rotate through the driving rod, gear 1 drives platform 1 to move, and gear 2 drives platform 2 to move, thereby realizing the telescopic function of the operating part.

[0015] Furthermore, a mounting groove is provided on the platform, and the driving rod, the gear 1 and the gear 2 are located in the mounting groove.

[0016] By adopting the above solution, the space occupied by the driving rod, gear one and gear two is reduced, and the volume of the operating table is reduced.

[0017] Furthermore, a layout groove 1 is provided on the lower surface of the table top 1, the rack 1 is installed in the layout groove 1, and the table top 1 is in contact with the table body; a layout groove 2 is provided on the lower surface of the table top 2, the rack 2 is installed in the layout groove 2, and the table top 2 is in contact with the table top 1.

[0018] By adopting the above solution, the volume of the operating table is saved on the one hand, and at the same time, the contact surface between the table body and the first table plate, and between the first table plate and the second table plate is larger, so that the operating table is more stable.

[0019] Furthermore, the inner wall of the arrangement groove 1 and the rack 1 are provided with a plurality of elastic members 1, and under the action of the elastic members 1, the rack 1 is meshed with the gear 1;

[0020] A plurality of elastic members are provided between the inner wall of the second arrangement groove and the second rack and the second table plate, and the second rack is disengaged from the second gear under the action of the second elastic members;

[0021] A guide slope and a guide plane are arranged on the upper surface of the second rack, the guide slope is lower on the side facing the parking space, and higher on the side away from the parking space, an adjustment rod is arranged above the second rack, one end of the adjustment rod is fixedly connected to the track, and an adjustment protrusion is fixedly connected to the other end of the adjustment rod, the adjustment protrusion abuts against the end of the guide slope away from the track, and when the adjustment protrusion moves to the end of the guide slope away from the parking space, the second rack meshes with the second gear;

[0022] A transition point is provided on one side of the slide rail away from the track, and when the second platform moves to the transition point, the adjustment protrusion moves to the end of the guide slope facing the track;

[0023] A mounting seat is fixedly connected to the inner wall of the arrangement groove 1 above the rack 1, a mounting protrusion is provided on one side of the mounting seat, an electromagnet is fixedly connected to the upper surface of the mounting protrusion, a connecting seat is fixedly connected to the upper surface of the rack 1, a connecting protrusion is fixedly connected to one side of the connecting seat, and the connecting protrusion is located above the electromagnet. When the electromagnet is powered on, the connecting protrusion is adsorbed and fixed to make the rack 1 mesh with the gear. When the electromagnet is powered off, the rack 1 is disengaged from the gear 1. A control switch is provided on one end of the table 1 facing the track. When the table 1 and the table 2 are in an overlapping state, the table 1 abuts against the control switch to power the electromagnet.

[0024] By adopting the above scheme, when the telescopic part needs to be extended, the driving motor is started to drive the driving rod to rotate. At this time, the platform two is in a pressed state with respect to the control switch, and the electromagnet is in a power supply state. Under the action of the electromagnet, it meshes with gear one, and the driving rod drives the platform one and the platform two to move toward the parking space through gear one. During the movement, the adjusting protrusion gradually moves along the guide inclined surface. In this process, the adjusting protrusion gradually presses the guide inclined surface downward, and when the platform one moves to the transition point, the adjusting protrusion moves to the end of the guide inclined surface away from the parking space, then enters the guide plane and continues to move.

[0025] When the telescopic part needs to be retracted, the driving motor starts and drives the driving rod to reverse. At this time, the platform two moves in the direction away from the parking space. When the adjusting protrusion moves to the end of the guide slope away from the parking space, the platform two presses the control switch. At this time, the electromagnet is powered, and the rack one meshes with the gear one under the action of the electromagnet. At this time, the platform one continues to move in the direction away from the parking space to make the telescopic part shrink to the initial position. In this way, the alternating telescopic function of the platform one and the platform two is realized by a motor variable.

[0026] Furthermore, the rack 1 includes a base portion 1 and a working portion 1, and an elastic member 3 is fixedly connected between the base portion 1 and the working portion 1.

[0027] By adopting the above scheme, when rack 1 moves downward under the action of elastic member 1 and engages with gear 1, elastic member 3 can play a buffering role, that is, when rack 1 and gear 1 initially contact, if rack 1 and gear 1 are not aligned, rack 1 can have a margin for upward movement.

[0029] By adopting the above scheme, the elastic member 4 can play a buffering role in the process of rack 2 moving downward and meshing with gear 2, that is, when rack 2 and gear 2 initially contact, if rack 2 and gear 2 are not aligned, rack 2 can have two margins for upward movement. After rack 2 and gear 1 are aligned, rack 2 meshes with gear 2, so that rack 2 and gear 2 can mesh more smoothly.

[0030] Furthermore, when the telescopic members on the two operating platforms move toward the parking space to a limit length, the two telescopic members abut against each other.

[0031] By adopting the above solution, when the staff needs to transfer from the welding point on one side of the transport vehicle to the welding point on the other side, the staff can transfer from the operating table on one side to the operating table on the other side without going down to the ground, saving time and effort and improving work efficiency.

[0033] S1. Vehicle size measurement

[0034] Measure the length, width and height of the vehicle to be modified to ensure that the vehicle to be modified meets the requirements of the displacement tooling;

[0035] S2. Parking

[0037] S3. Determine the welding point

[0038] Determine the welding points of the vehicle and the welding sequence of each welding point;

[0039] S4. Operating table position adjustment

[0040] Move the operating table to the first welding point;

[0041] S5. Go up to the operating table and weld each point in turn

[0042] The staff climbs onto the operating table and welds the first welding point first. After the welding of the first welding point is completed, the operating table is adjusted to accommodate the second welding point by adjusting the horizontal position and vertical height of the operating table and the extension length of the telescopic part through drive components one and two, and the welding of each point is carried out in sequence.

After one welding point is completed, the staff can quickly adjust to the next welding position through the driving assembly 1 and the driving assembly 2, making the whole welding process more convenient and quick. When the staff needs to transfer from the welding point on one side of the transport vehicle to the welding point on the other side, the staff can transfer from the operating table on one side to the operating table on the other side without going down to the ground, saving time and effort and improving work efficiency.

When the electromagnet 711 is powered off, the rack 4 is disengaged from the gear 3252. A control switch 8 is provided at one end of the table 321 facing the track 25. When the table 321 and the table 2 322 are in an overlapping state, the table 321 abuts against the control switch 8 to power the electromagnet 711.

[0075] When the telescopic member 32 needs to be extended, the driving motor 3254 is started to drive the driving rod 3251 to rotate. At this time, the platform 2 322 is in a pressed state with respect to the control switch 8, and the electromagnet 711 is in a powered state. Under the action of the electromagnet 711, it meshes with the gear 1 3252. The driving rod 3251 drives the platform 1 321 and the platform 2 322 to move toward the parking space 11 through the gear 1 3252. During the movement, the adjusting protrusion 61 gradually moves along the guiding inclined surface 512.

At this time, the rack 1 4 is released from the gear 1 3252 under the action of the elastic member 1 3213, and the platform 1 321 continues to move alone in the direction toward the parking space 11.

[0076] When the telescopic member 32 needs to be retracted, the driving motor 3254 is started to drive the driving rod 3251 to reverse. At this time, the platform 322 moves in the direction away from the parking space 11. When the adjusting protrusion 61 moves to the end of the guide slope 512 away from the parking space 11, the platform 322 forms a press on the control switch 8. At this time, the electromagnet 711 is powered, and the rack 4 engages with the gear 3252 under the action of the electromagnet 711. At this time, the platform 321 continues to move in the direction away from the parking space 11 to make the telescopic member 32 shrink to the initial position. In this way, the alternating telescopic function of the platform 1 321 and the platform 2 322 is realized by a motor variable.

[0077] Furthermore, the rack 4 includes a base part 41 and a working part 42, the rack is located on the working part 42, an elastic member 43 is fixedly connected between the base part 41 and the working part 42, and the elastic member 43 is generally a spring. A guide groove 413 is vertically opened at the bottom of the base part 41, and a guide column 421 is fixedly connected to the corresponding working part, and the guide column is slidably connected to the guide groove 413.

[0078] In the process of rack-4 moving downward and meshing with gear-3252 under the action of elastic member-3213, elastic member-343 can play a buffering role, that is, when rack-4 and gear-3252 are initially in contact, if rack-4 and gear-3252 are not aligned, rack-4 can have a margin for upward movement. After rack-4 and gear-3252 are aligned, rack-4 meshes with gear-3252, so that rack-4 and gear-3252 can mesh more smoothly. In addition, the cooperation of guide column-421 and guide groove-413 can make the connection between base part-41 and working part-42 more stable. At the same time, when rack-4 and gear-3252 are fully meshed together, the margin for upward movement of working part-42 is less than the depth of the tooth groove of gear-3252, thereby preventing gear-3252 from being separated from rack-4 during the movement of table-321.

[0079] The rack 2 5 includes a base part 2 51 and a working part 2 52. The rack is located on the working part 2 52. An elastic member 4 53 is fixedly connected between the base part 2 51 and the working part 2 52. The elastic member 4 53 is generally a spring. A guide groove 2 513 is vertically opened at the bottom of the base part 2 51. A guide column 2 521 is fixedly connected to the corresponding working part. The guide column 2 521 is slidably connected to the guide groove 2 513. The guide slope 512 is located at the base part 2 51.

[0080] In the process of the rack 25 moving downward and meshing with the gear 2 3253, the elastic member 4 53 can play a buffering role, that is, when the rack 25 and the gear 2 3253 are initially in contact, if the rack 25 and the gear 2 3253 are not aligned, the rack 25 can have two margins for upward movement. After the rack 25 is aligned with the gear 1 3252, the rack 25 meshes with the gear 2 3253, so that the rack 25 and the gear 2 3253 can be meshed together more smoothly. In addition, the cooperation of the guide column 2 521 and the guide groove 2 513 can make the connection between the base part 2 51 and the working part 2 52 more stable. At the same time, when the rack 25 and the gear 2 3253 are fully meshed together, the margin for the upward movement of the working part 2 52 is less than the depth of the tooth groove of the gear 2 3253, thereby preventing the gear 2 3253 from being separated from the rack 2 5 during the movement of the table 2 322.

[0081] The implementation principle of the present application is as follows: the staff can drive the vehicle to the parking space 11 through the driving slope 12 to stop, and then according to the position of the welding point, the operating platform 3 is moved to the position, and the height of the operating platform 3 is lowered to make it convenient for the staff to board the operating platform 3. After the staff board the operating platform 3, the operating platform 3 is raised to a suitable height and the length of the operating platform 3 is adjusted. After the operating platform 3 is adjusted to a suitable position, the staff starts welding. When a welding point is completed, the staff can quickly adjust to the next welding position through the drive component 1 25 and the drive component 2 26, making the entire welding process more convenient and quick. When the staff needs to transfer from the welding point on one side of the transport vehicle to the welding point on the other side, the staff can transfer from the operating platform 3 on one side to the operating platform 3 on the other side without going down to the ground, saving time and effort and improving work efficiency.

[0082] A chemical liquid transport vehicle welding process based on a welding displacement tool comprises the following steps:

[0083] S1. Vehicle size measurement

[0084] Measure the length, width and height of the vehicle to be modified to ensure that the vehicle to be modified meets the requirements of the displacement tooling;

[0085] S2. Parking

[0086] Park the vehicle to be modified on the parking space of the base via the driving ramp

[0087] S3. Determine the welding point

[0088] Determine the welding points of the vehicle and the welding sequence of each welding point;

[0089] S4. Operating table position adjustment

[0090] Move the operating table 3 to the first welding point;

[0091] S5. Go up to the operating table and weld each point in turn

[0092] The staff climbs onto the operating platform 3 and first welds the first welding point. After the welding of the first welding point is completed, the driving component 1 25 and the driving component 2 26 are used to adjust the horizontal position and the vertical height of the operating platform 3, as well as the extension length of the telescopic member 32 so that the operating platform 3 can adapt to the second welding point, and the welding of each point is carried out in sequence.
