The main platform is provided with a telescopic groove, the first connecting tube is slidably connected in the telescopic groove, the second connecting tube is slidably connected in the first connecting tube, the main rod is slidably connected in the second connecting tube, and the main rod fixes the telescopic platform.

[0007] By adopting the above technical solution, the vertical driving structure tends to make the lifting platform slide vertically. When welding the storage tank, the worker stands on the lifting platform to raise the worker to the required height, and then the horizontal driving mechanism moves the telescopic platform away from the main platform, which is convenient for adjusting the welding position. When the telescopic platform slides away from the main platform, the main rod slides out of the second connecting tube, the second connecting tube slides out of the first connecting tube, and the first connecting tube slides out of the telescopic groove, making the telescopic platform easy to slide. The welding of the present application solution moves to the operating platform, which is easy to operate and has a simple structure, greatly improving the welding convenience of workers.

[0008] Optionally, the horizontal driving mechanism includes two groups of supporting guard frames and two groups of electric push rods, the telescopic platform is fixed at the bottom of the supporting guard frames, the electric push rods are fixed on the supporting guard frames, the telescopic axes of the electric push rods face one side of the main platform, the two electric push rods are located on the left and right sides of the telescopic platform, a fixed frame is fixed on the main platform, the telescopic ends of the two electric push rods are fixed to the fixed frame, and the pushing direction of the electric push rods is the same as the moving direction of the telescopic platform;

[0010] By adopting the above technical solution, the support frame supports the electric push rod on the left and right sides of the telescopic platform, and the telescopic axis of the electric push rod faces the main platform. When the worker is on the telescopic platform, the electric push rod can be used as a handrail to prevent the worker from falling from both sides of the platform. The first fixing member, the second fixing member and the third fixing member enable the telescopic slot, the first connecting pipe, the second connecting pipe and the main rod to slide against each other constantly, but they cannot be separated from each other.

[0011] Optionally, the first fixing member includes a first fixing cylinder, a first fixing pin and a first fixing spring, the first fixing cylinder is fixed to the main platform, the first fixing pin is slidably connected to the first fixing cylinder, the first fixing spring drives the first fixing pin to press against the first connecting tube, the first connecting tube is provided with a first pin hole for inserting the first fixing pin at one end away from the telescopic platform, and the first fixing pin is provided with a first chamfered surface for abutting against an orifice of the first pin hole at a side close to the telescopic platform.

[0012] By adopting the above technical solution, when the first fixing pin makes the first connecting tube slide away from the main stage and is about to leave the telescopic slot, the first fixing pin is inserted into the first pin hole, so that the first connecting tube cannot slide away from the main stage, thereby limiting the first connecting tube from leaving the telescopic slot. When the first connecting tube wants to retract into the telescopic slot, the opening of the first pin hole abuts against the first chamfered surface, so that the first plug pin is pushed up, and the first connecting tube can be retracted at this time.

[0016] The moving assembly also includes a reduction box and a moving motor. The reduction box is fixed to the base. The input end of the reduction box is connected to the motor shaft of the moving motor. The input end of the reduction box is connected to the main shaft.

[0017] By adopting the above technical solution, the mobile motor drives the main shaft to rotate, thereby driving the mobile wheel to rotate, the track is limited in the bottom groove, and the mobile wheel is supported on the track, so as to move the base. The modified wall slide rail has good load-bearing capacity and is not afraid of dust and debris affecting the sliding of the base. The base is easy to move, and the moving direction of the base is horizontal to the body platform, and the moving directions of the two are perpendicular. Combined with the vertical movement of the lifting platform, it is convenient for workers on the telescopic platform to adjust their positions.

[0018] Optionally, it also includes a protection component arranged at the end of the telescopic platform away from the main platform, the protection component includes a protection vertical plate and a protection drive structure for driving the protection vertical plate to rise and fall, the top surface of the end of the telescopic platform away from the main platform is provided with a vertical groove, the protection vertical plate is slidably connected in the vertical groove, and the protection vertical plate is located between two electric push rods; it also includes a control box and an induction switch electrically connected to the control box, after the induction switch senses that the lifting platform has risen, the control box controls the protection drive structure to drive the protection vertical plate to rise; when the induction switch senses that the lifting platform is at the lowest position, the control box controls the protection drive structure to drive the protection vertical plate to descend.

[0019] By adopting the above technical solution, when the lifting platform is at a high place, the induction switch senses that the lifting platform is rising, and the control box controls the protection drive structure to drive the protection vertical plate to rise, and the worker is limited between the protection vertical plate and the two electric push rods, thereby improving the safety of the operation. When the induction switch senses that the lifting platform is at the lowest position, the control box controls the protection drive structure to drive the protection vertical plate to descend, so that a gap appears at the protection vertical plate, which is convenient for workers to extend and retract the platform up and down.

[0020] Optionally, a storage assembly is provided on the protective vertical plate, and the storage assembly includes a storage plate and two hinged rods provided on both sides of the top of the storage plate;

[0021] One end of the hinged rod is hinged to the side end surface of the protective vertical plate, and the side wall of the hinged rod is provided with an adjustment slot, and the length direction of the adjustment slot is the same as the length direction of the hinged rod;

[0023] By adopting the above technical solution, when the storage plate rises, due to gravity, the storage plate flips away from the protective vertical plate to an inclined state and is pulled by the hinged rod, so that a storage space is formed between the storage plate and the protective vertical plate, and welding tools can be placed in the storage space. Otherwise, workers need to squat and place the tools on the telescopic platform, which is more troublesome. When the protective vertical plate descends, the notch of the vertical groove abuts against the outer wall of the storage plate, so that the storage plate rotates to a vertical state. At this time, the hinged rod is also in a vertical state, and the storage plate and the hinged rod can pass through the vertical groove. The top of the storage plate is limited in the vertical groove so that the vertical groove will not expand. When the protective vertical plate slides up, the storage plate will not hinder the sliding of the protective vertical plate.

[0024] Optionally, when the protective vertical plate slides to a point where its top is lower than the top surface of the telescopic platform or the top surface of the protective vertical plate is flush with the top surface of the telescopic platform, the storage plate and the hinged rod are located in the lower direction of the telescopic platform, and the hinge point of the hinged rod and the protective vertical plate is higher than the hinge point of the hinged rod and the storage plate; the accommodating groove and the storage plate are arranged on the side of the protective vertical plate away from the main platform, and two abutment blocks are arranged at the bottom of the telescopic platform, and when the hinged rod slides up and approaches the abutment block, the end of the abutment block abuts against the top surface of the hinged rod to drive the hinged rod to rotate downward to a vertical position, and when the hinged rod rotates downward to a vertical position, the storage plate is stored in the accommodating groove.

[0025] By adopting the above technical solution, the storage board is set on the outside of the protective vertical board. When the storage board is in the unfolded state, the top of the storage board protrudes out of the end of the telescopic platform away from the main platform, so that when the storage board is in the lowered state, the storage board can serve as a step for workers to step on and climb onto the telescopic platform, making it convenient to climb onto the telescopic platform. The setting of the abutment block allows the protective vertical board to slide up, and the abutment block abuts the hinged rod to limit the hinged rod in a vertical state. At this time, the storage board is also in a vertical state, and the placement board is stored in the receiving groove, which facilitates the protective vertical board to rise through the vertical groove. When the hinged rod is separated from the abutment block, the storage board is unfolded, which facilitates the placement of items.

[0026] Optionally, a weight-reducing groove is provided at the bottom of the telescopic platform, the abutment block is provided in the weight-reducing groove, and two abutment blocks abut against two ends of the protective vertical plate.

[0027] By adopting the above solution, the weight-reducing groove reduces the weight of the telescopic platform and reduces the burden on the telescopic structure. The abutment block abuts against both ends of the protective vertical plate, increasing the area of ​​the vertical surface contacted by the protective vertical plate, thereby limiting the direction of the protective vertical plate and improving the sliding stability of the protective vertical plate.

[0028] Optionally, the protection drive structure includes a protection motor, a protection screw, a protection gear and a protection rack. Both ends of the protection screw are rotatably connected to the bottom of the telescopic platform. The protection gear coaxially fixes the protection screw. The protection motor drives the protection screw to rotate. The length direction of the protection rack is vertical.

[0029] By adopting the above technical solution, the protection motor drives the protection screw to rotate, thereby driving the protection gear to rotate, and the protection gear drives the protection rack to rise and fall, thereby realizing the lifting and lowering of the protection vertical plate. The setting of the weight reduction groove facilitates the installation of the protection gear and the protection screw.

When the protective vertical plate 71 passes through the vertical groove 421, the storage plate 91 is stored in the receiving groove 94.

[0067] Reference Figure 8 An anti-drop-off plate 95 is fixed to the top surface of the protective vertical plate 71. The outer diameter of the anti-drop-off plate 95 is larger than the outer diameter of the top end of the protective vertical plate 71. An anti-drop-off groove 96 for accommodating the anti-drop-off plate 95 is circumferentially opened at the top of the vertical groove 421 to prevent the protective vertical plate 71 from easily falling off the vertical groove 421. When the anti-drop-off plate 95 is located in the anti-drop-off groove 96, the top surface of the anti-drop-off plate 95 is flush with the top surface of the telescopic platform 42.

[0068] Reference Figure 7 , Figure 8 When the storage plate 91 slides until the top of the storage plate 91 is lower than the top surface of the telescopic platform 42 or the top surface of the storage plate 91 is flush with the top surface of the telescopic platform 42, the storage plate 91 and the hinged rod 92 are completely located below the telescopic platform 42, and the hinged part of the hinged rod 92 and the protective vertical plate 71 is higher than the hinged part of the hinged rod 92 and the storage plate 91.

[0069] Reference Figure 7 The receiving groove 94 and the storage plate 91 are located on the side of the protective vertical plate 71 away from the main platform 41. Two abutment blocks 97 are fixed at the bottom of the telescopic platform 42. When the protective vertical plate 71 slides up, the hinged rod 92 slides up and approaches the abutment block 97. The end of the abutment block 97 abuts the top surface of the hinged rod 92 to drive the hinged rod 92 to rotate downward to the vertical direction. When the hinged rod 92 rotates downward to the vertical direction, the storage plate 91 is stored in the receiving groove 94, which facilitates the sliding of the protective vertical plate 71 in the vertical groove 421. The end of the abutment block 97 used to abut the hinged rod 92 is chamfered, so that the hinged rod 92 is easy to turn and not easily stuck.

[0070] Reference Figure 7The two abutting blocks 97 abut against the side walls of the protective vertical plate 71. Due to the provision of the weight-reducing groove 422, the inner wall area of ​​the vertical groove 421 is small, and the abutting blocks 97 abut against the side walls of the protective vertical plate 71, thereby increasing the contact area of ​​the protective vertical plate 71 and stabilizing the sliding.

[0071] The implementation principle of a welding mobile operation platform in the embodiment of the present application is that when in use, the mobile motor 25 drives the screw to rotate and drives the mobile wheel 22 to rotate, so that the base 1 slides on the ground. The winder 51 controls the vertical movement of the lifting platform 4 by winding and releasing the wire. Two electric push rods 432 drive the telescopic platform 42 to move horizontally. When the worker is on the telescopic platform 42, he carries a remote control and gives the control box 8 through the remote control button. The control box 8 drives the telescopic platform 42 to move in the horizontal and vertical directions, which is convenient for adjusting the welding position and making welding convenient.

[0072] When climbing onto the telescopic platform 42, the placement plate is located below the telescopic platform 42, and the placement plate is used as a step for workers to step on, so as to facilitate climbing onto the telescopic platform 42. When the telescopic platform 42 rises, the induction switch 81 senses that the telescopic platform 42 has risen, and the control box 8 controls the protection motor 721 to start, and transmits through the protection gear 723 and the protection rack 724, so that the protection vertical plate 71 slides up. When sliding up, the abutment block 97 abuts against the hinged rod 92 and rotates to the vertical direction. At this time, the placement plate is stored in the receiving groove 94, and the protection vertical plate 71 slides up conveniently. After the hinged rod 92 is separated from the abutment block 97, the placement plate rotates in the direction away from the protection vertical plate 71, forming a placement space, which is convenient for workers to prevent items.

[0073] The above are all preferred embodiments of the present application, and the protection scope of the present application is not limited thereto. Therefore, any equivalent changes made according to the structure, shape, and principle of the present application should be included in the protection scope of the present application.
