Description

Technical Field

[0001] This utility model relates to the field of maintenance platforms, and in particular to a convenient maintenance support platform for nitrogen generators. Background Technology

[0002] A nitrogen generator is a device that uses air as raw material and separates oxygen and nitrogen using physical methods to obtain nitrogen gas. Long-term use of nitrogen generators may lead to damage, requiring maintenance of the nitrogen generator tank. Currently, most nitrogen generator tanks have curved bottom and top surfaces. For comprehensive inspection, it is sometimes necessary to move the entire tank out of the mounting frame. Existing products use a trolley with grippers to hold the tank from both sides, lift it, and move it onto the trolley for further inspection and maintenance. However, the inventor believes that existing gripper methods are not stable enough. Excessive gripping force can deform the tank, while insufficient force can cause it to fall and break. Therefore, the reliability of simple gripper methods for transferring nitrogen generator tanks is poor, making it difficult to meet the relocation requirements for maintenance and inspection.

Two sets of shovels are symmetrically mounted on the outer side of the movable seat. A fixed frame is fixedly connected to the outer side of the support trolley near its upper end. A guide groove is through the outer end of the fixed frame, and a rectangular rod is slidably inserted into the guide groove. Two sets of symmetrical bent rods are movably mounted on the bottom of the fixed frame on both sides of the rectangular rod. A threaded shaft extending into the inner cavity of the fixed frame is threadedly connected to the inner side of the support trolley, and the threaded shaft drives the rectangular rod and the bent rods on both sides to engage with the outer side of the nitrogen generator tank.

[0005] Preferably, the bottom of the support trolley is provided with a movable base, the bottom of the movable base is provided with omnidirectional wheels with foot brakes, and a push handle is fixedly connected to the outside of the support trolley.

[0010] Compared with the prior art, the present invention has the following beneficial effects;

[0011] This invention utilizes two sets of symmetrical shovels on the outer side of the bottom of a support trolley to connect with the arc-shaped surface of the bottom of a nitrogen generator tank commonly found in existing designs. Simultaneously, a gripper mechanism on the outer side of the upper end of the support trolley is used to limit and clamp the outer side of the nitrogen generator tank. Finally, the shovels are raised to a certain height and then moved to a maintenance position. Throughout the entire process, the nitrogen generator tank can be moved using only the support and limiting structure, effectively maintaining the relative stability of the tank during the transfer. This also effectively avoids the drawbacks of simply clamping and transferring in existing technologies, and has significant practical effects and improved portability, which is beneficial for maintenance work.

[0020] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments.

[0021] Reference Figure 1-4A convenient maintenance support platform for a nitrogen generator includes a support trolley 1 for transferring the nitrogen generator tank. The support trolley 1 has a slot 2 extending through its front. A through groove 3 communicating with the slot 2 is provided through the outer side of the support trolley 1. A movable seat 4 is longitudinally mounted on the outer side of the support trolley 1, sliding through the through groove 3 and extending into the inner cavity of the slot 2. Two sets of shovels 5 are symmetrically installed on the outer side of the movable seat 4. A fixed frame 6 is fixedly connected to the outer side of the support trolley 1 near its upper end. A guide groove 7 is provided through the outer end of the fixed frame 6, and a rectangular... The bottom of the rod 8 and the fixed frame 6 are provided with two sets of symmetrical bent rods 9 on both sides of the rectangular rod 8. The inner side of the support trolley 1 is threadedly connected to a threaded shaft 10 that extends into the inner cavity of the fixed frame 6. The threaded shaft 10 drives the rectangular rod 10 and the bent rods 9 on both sides to engage with the outside of the nitrogen generator. The inner end of the rectangular rod 8 is fixedly connected to a movable block 1001, and the movable block 1001 is rotatably connected to the threaded shaft 10. The two sides of the movable block 1001 are symmetrical inclined surfaces, and the movable block 1001 is in contact with the inner end of the bent rod 9 through the inclined surfaces on both sides.

[0022] It should be added that the two sets of shovels 5 have an inclined surface structure on the opposite side, and the shovels 5 slide in contact with the bottom of the nitrogen generating tank through the inclined surface of the mating surface.

[0023] Based on the above structural configuration, during use, the height of the two sets of shovels 5 at the bottom of the support trolley 1 is adjusted, and then the support trolley 1 is pushed forward so that the shovels 5 can be smoothly inserted into the bottom of the nitrogen generating tank and align with its bottom arc-shaped surface. The forward movement distance is adjusted to ensure that the bent rod 9 on the outside of the fixed frame 6 also aligns with the outside of the nitrogen generating tank. Then, the outer threaded shaft 10 rotates and threadedly pushes the movable block 1001 and the connected rectangular rod 8 outward along the guide groove 7. During the movement of the movable block 1001, the two... The inclined side of the tube contacts the inner end of the bent rod 9, thereby driving the bent rod 9 to rotate and adjust the angle. The outer ends of the rectangular rod 8 and the bent rod 9 are used to clamp the tube to the outside of the nitrogen generator. Then, the height of the shovel plate 5 is raised to lift the nitrogen generator. During this process, the two sets of shovel plates 5 support the bottom sides of the nitrogen generator, while the nitrogen generator is limited by the rectangular rod 8 and the two sets of bent rods 9. Therefore, the nitrogen generator will not slip off the device and can maintain relative stability, making it easy to transfer it to the maintenance location.

[0024] The support trolley 1 has a movable base at its bottom, and the movable base has casters with foot brakes at its bottom. A push handle is fixedly connected to the outside of the support trolley 1. After the nitrogen generator tank is clamped and fixed, the support trolley 1 can be pushed to move in conjunction with the casters at the bottom by pushing the handle, so as to facilitate the repositioning of the nitrogen generator tank and achieve fixation in conjunction with the foot brake.

[0025] The slot 2 has a threaded rod 201 rotatably connected to the inner wall, and the threaded rod 201 is threaded through the movable seat 4. The support trolley 1 has a drive shaft 202 rotatably connected to the outer side, and the inner end of the drive shaft 202 extends into the inner cavity of the slot 2. Both the inner end of the drive shaft 202 and the outer side of the threaded rod 201 are fixedly fitted with meshing bevel gears 203. After the nitrogen generating tank is locked and limited by the rectangular rod 10 and the bent rods 9 on both sides, the drive shaft 202 can drive the bevel gear 203 at the inner end to rotate and mesh with the bevel gear on the outer side of the threaded rod 202, thereby driving the threaded rod 202 to rotate. The threaded rod 202 drives the movable seat 4 to slide longitudinally along the through slot 3, lifting the nitrogen generating tank supported by the two sets of shovels 5 on the outer side of the movable seat 4, making it easy to transfer it away from the outside of the nitrogen generator.

[0026] The movable base 4 has a through-hole 401 connecting to the inner cavity on its outer side. The inner end of the shovel plate 5 is slidably disposed within the through-hole 401. Positioning holes 402 are provided at the upper ends of both the movable base 4 and the shovel plate 5, with multiple sets of these holes evenly distributed. A positioning pin 403 is provided at the upper end of the movable base 4, passing through the positioning holes 402 at the upper ends of both the movable base 4 and the shovel plate 5. Since the width and arc surface size of the bottom of different nitrogen generator tanks vary, the positions of the two sets of shovel plates 5 in the through-hole 401 on the outer side of the movable base 4 can be adjusted according to the specifications of the nitrogen generator tank. This position is approximate and does not need to be particularly precise, as they will still abut against the arc surface of the bottom of the nitrogen generator tank during subsequent lifting. After adjusting the position, the shovel plate 5 is positioned by inserting the positioning pin 403 through the positioning hole 402 at the upper end of the movable base 4 and then inserting it into the positioning hole 402 at the upper end of the shovel plate 5, thus facilitating stable use later.

[0027] Rubber turntables 902 are provided at the outer ends of both the bending rod 9 and the threaded shaft 10. The rubber turntables 902 are rotatably connected to the bending rod 9 and the threaded shaft 10, as well as to the bending rod 9 and the fixed frame 6, via rotating shafts 901. The rubber turntables 902 can movably contact the outer side of the nitrogen generator and compress and limit its movement. This compression force does not need to be too large, effectively reducing wear on the contact surface of the nitrogen generator.

[0028] The above embodiments are preferred embodiments of the present utility model, but the embodiments of the present utility model are not limited to the above embodiments. Any changes, modifications, substitutions, combinations, or simplifications made without departing from the spirit and principle of the present utility model shall be considered equivalent substitutions and shall be included within the protection scope of the present utility model.

[0029] In the description of this utility model, it should be understood that the terms indicating orientation or positional relationship are based on the orientation or positional relationship shown in the drawings, and are only for the convenience of describing this utility model and simplifying the description, and are not intended to indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation, and therefore should not be construed as a limitation of this utility model.
