Description

Technical Field

[0001] This utility model relates to the field of maintenance trolley technology, specifically a chemical maintenance equipment trolley. Background Technology

[0002] Chemical maintenance equipment trolleys are specialized tool carts used in chemical production environments for transporting, inspecting, and maintaining equipment. These trolleys are typically designed and manufactured according to the specific needs and working environment of chemical sites to ensure that work efficiency is effectively improved, personnel safety is guaranteed, and equipment damage is reduced during maintenance.

[0003] Compared to traditional trolleys, chemical trolleys, taking into account the weight and size of chemical equipment, typically have a higher load-bearing capacity and larger storage space. Furthermore, considering the hazardous nature of chemical equipment, the design of these trolleys should prioritize ease of use for maintenance personnel. Currently, most trolleys used by maintenance workers in chemical plants for placing and moving maintenance tools are traditional trolleys. These trolleys have a simple structure and an unreasonable allocation of internal storage space, leading to disorganized storage of chemical products or equipment. Additionally, the fixed maintenance platform prevents adjustments to the equipment's angle during maintenance, adding to the workload of maintenance personnel. Utility Model Content

[0004] The purpose of this utility model is to provide a chemical maintenance equipment trolley to solve the problems mentioned in the background art.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a chemical maintenance equipment trolley, including a chassis, a storage box fixedly connected to the upper part of the chassis, several sets of limiting plates fixedly connected to both sides inside the storage box, an isolation plate slidably connected between the limiting plates, a rotating cylinder fixedly connected to the upper middle part of the storage box, a rotating platform rotatably connected inside the rotating cylinder, a locking gear fixedly connected to the lower part of the rotating platform, a gear groove cooperating with the locking gear fixedly connected to the lower interior of the rotating cylinder, a shielding ring fixedly connected to the upper part of the rotating cylinder, and a maintenance platform fixedly connected to the upper part of the rotating platform through the shielding ring.

[0019] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0020] Please see Figure 1-4 This utility model provides a technical solution: a chemical maintenance equipment trolley, including a base plate 1, a storage box 2 fixedly welded to the upper part of the base plate 1, several sets of limiting plates 3 fixedly welded to both sides inside the storage box 2, and partition plates 4 slidably installed between the limiting plates 3. By inserting multiple sets of partition plates 4 between different layers of limiting plates 3 as needed, the storage box 2 is divided into spaces of different heights, facilitating the storage of equipment of different sizes according to needs. A rotating cylinder 5 is fixedly welded to the upper middle part of the storage box 2, and a rotating platform 6 is rotatably installed inside the rotating cylinder 5. A locking gear 18 is fixedly welded to the lower part of the rotating platform 6. The lower side of the cylinder 5 is fixedly welded with a gear groove 20 that matches the locking gear 18. The locking gear 18 at the bottom of the rotating platform 6 can rotate arbitrarily along the upper part of the inner side of the rotating cylinder 5. The locking gear 18 is inserted into the gear groove 20 at the bottom of the rotating cylinder 5, thereby locking the rotating platform 6. The upper part of the rotating cylinder 5 is fixedly welded with a shielding ring 19 to prevent the locking gear 18 from disengaging from the rotating cylinder 5 when it rises. The upper part of the rotating platform 6 is fixedly welded with a maintenance platform 7 through the shielding ring 19. The maintenance equipment is placed on the maintenance platform 7 for maintenance. At the same time, the rotating platform 6 can drive the maintenance platform 7 to rotate arbitrarily, which is convenient for maintenance from different angles.

[0021] The storage box 2 has several sets of connecting holes 8 on one side, which are located between the limiting plates 3. A locking rod 9 is slidably installed inside the connecting holes 8 and one side of the isolation plate 4. A connecting rod 10 is fixedly welded to the other end of the locking rod 9. A third screw 11 is threaded onto the upper side of the connecting rod 10. The tail of the third screw 11 is rotatably connected to the outer wall of the storage box 2. By rotating the third screw 11, the connecting rod 10 is moved, causing the locking rod 9 to be inserted into one side of the isolation plate 4 through the connecting holes 8, thus locking the isolation plate 4. Connecting plates 12 are fixedly welded to both sides of the upper part of the storage box 2. A rotating shaft 13 is rotatably mounted between the middle of the shaft and the floor 1. A door 14 is fixedly welded to the outside of the rotating shaft 13. A connecting piece 15 is fixedly welded to the upper part of the rotating shaft 13 through the connecting plate 12. A first screw 16 is threaded on one side of the connecting piece 15. First positioning holes 17 are provided on both sides of the upper part of the connecting plate 12 to engage with the first screw 16. The rotating shaft 13 drives the door 14 to rotate. When the door 14 rotates to the closed or fully open position, the first screw 16 connects to the first positioning holes 17 to fix the opening and closing position of the door 14, preventing the door 14 from rotating arbitrarily. The maintenance platform 7 has sliding baffles 24 installed on both sides. By moving the baffles 24 up and down along the platform 7, the baffles 24 can be extended or retracted according to maintenance needs. When extended, the baffles 24 prevent small parts from slipping off the platform 7; when retracted, the baffles 24 prevent their protrusion from interfering with normal maintenance. Two sets of second positioning holes 26 are provided on the outer side of the baffles 24. Second screws 25, which mate with the second positioning holes 26, are threaded onto both sides of the platform 7. By rotating the second screws 25, different second positioning holes 26 are connected, thereby adjusting the position of the baffles 24. The rotating cylinder 5 is locked in place; a mounting plate 21 is fixedly welded to one side, and a fourth screw 22 is threadedly connected inside the mounting plate 21. A rubber pad 23 is rotatably mounted on the upper part of the fourth screw 22. By rotating the fourth screw 22, the rubber pad 23 lifts the inspection platform 7, making it easy to lift the inspection platform 7 and disengage the locking gear 18 from the gear groove 20; four sets of wheels 28 are threadedly installed on the lower part of the chassis 1, which can drive the equipment to move freely. The wheels 28 have a locking structure, and their self-locking structure ensures the stability of the equipment when it is parked; a handrail 27 is fixedly welded to one side of the upper part of the chassis 1, which facilitates the movement of the equipment.

[0022] Working principle: When in use, this utility model divides the storage box 2 into spaces of different heights by inserting multiple sets of isolation plates 4 between different layers of restriction plates 3 as needed. This facilitates the storage of equipment of different sizes according to requirements. The equipment to be repaired is placed on the repair platform 7. By rotating the fourth screw 22, the rubber pad 23 lifts the repair platform 7, making it easy to lift the repair platform 7 and disengage the locking gear 18 from the gear groove 20. The locking gear 18 at the bottom of the rotating platform 6 can rotate arbitrarily along the upper inner side of the rotating cylinder 5, allowing the rotating platform 6 to drive the repair platform 7 to rotate arbitrarily, facilitating maintenance from different angles. The locking gear 18 is inserted into the gear groove 20 at the bottom of the rotating cylinder 5, thereby locking the rotating platform 6.
