Description

Technical Field

[0001] The utility model belongs to the technical field of subway vehicle maintenance equipment, and more specifically, relates to a subway air conditioner disassembly and maintenance platform. Background Art

[0002] Subway air conditioning is an air conditioning system installed on subway trains to regulate the temperature, humidity, air flow and cleanliness inside the train. Its main purpose is to provide a comfortable environment for drivers and passengers, while also helping to protect electrical equipment and other facilities inside the train from harsh environments.

[0003] The fresh air units for subway air conditioners are located on both sides of the train's roof. When removing and installing the fresh air filters, maintenance and repair work requires workers to climb onto the train's roof. Although equipped with safety ropes, the units' location near the train's edge forces them to squat and lean over the roof to remove and install the filters, making the process inconvenient and potentially hazardous. Utility Model Content

[0004] The purpose of the utility model is to provide a subway air conditioner disassembly and maintenance platform, which is designed to facilitate staff to disassemble and assemble the fresh air filter on the subway air conditioner.

[0005] To achieve the above-mentioned purpose, the technical solution adopted by the present invention is to provide a subway air conditioner disassembly, assembly and maintenance platform, including:

[0006] A platform car is set on the outside of the train and moves along the train;

[0007] An operating platform is provided on the platform vehicle and is raised and lowered by a linear drive assembly, and is used to lift the operator to the working height;

[0008] A guardrail is fixedly arranged on the operating platform and encloses a space for accommodating the work of the staff;

[0009] A storage box is fixedly arranged on the operating platform, and a plurality of slots for accommodating fresh air filters are evenly distributed along the length of the storage box, so that the fresh air filters are suitable for vertical insertion into any of the slots; and

[0010] A plurality of ejection components are provided on the storage box and correspond one-to-one to the slots, and are used to eject the fresh air filter from the slots.

[0011] In one possible implementation, the ejection assembly includes:

[0012] An elastic ejector, located at the bottom of the slot, has elastic freedom of vertical movement and is used to push the fresh air filter upward to extend from the top of the slot;

[0013] an elastic locking member, located on a side of the elastic ejection member, having elastic freedom of lateral movement, and used for locking the position of the elastic ejection member;

[0014] a pressure rod, vertically slidably disposed on the storage box and abutting against the elastic locking member, for pushing the elastic locking member to move laterally and unlock the elastic ejecting member;

[0015] When the fresh air filter is inserted into the slot, the fresh air filter presses against the upper surface of the elastic ejection member, so that the elastic ejection member is compressed and the elastic locking member locks the elastic ejection member;

[0016] When the pressure rod moves downward, the elastic locking member unlocks the elastic ejecting member, so that the elastic ejecting member is released from compression and pushes the fresh air filter upward.

[0017] In a possible implementation, the elastic ejector includes:

[0018] A top block is vertically slidably disposed on the storage box and is located at the bottom of the slot;

[0019] The first elastic member is arranged between the storage box and the top block and is used to push the top block upward.

[0020] In a possible implementation, the elastic ejection member further includes a limiting rod fixedly provided on the lower surface of the ejection block, the limiting rod is slidably connected to the storage box, and the first elastic member is sleeved on the limiting rod.

[0021] In a possible implementation, the elastic locking member includes:

[0022] A locking block is arranged on the storage box for transverse sliding movement;

[0023] a second elastic member, disposed between the storage box and the locking block, and configured to push the locking block toward the top block;

[0024] Wherein, when the top block is retracted into the storage box and the first elastic member is compressed, the locking block is plugged into the top block.

[0025] In a possible implementation, the locking block has a guide slope at one end close to the top block. When the top block moves downward, the top block abuts against the guide slope and pushes the locking block to move laterally, so that the locking block avoids the top block.

[0026] In a possible implementation, the lower surface of the pressure rod has a push-up inclined surface. When the pressure rod moves downward, the push-up inclined surface abuts against the locking block and pushes the locking block to move laterally, so that the locking block is disengaged from the push block.

[0027] In one possible implementation, the linear drive assembly includes:

[0028] A guide rod, vertically fixed on the platform vehicle;

[0029] A sliding sleeve, which is arranged on the guide rod and fixed to the operating platform;

[0030] A screw rod is vertically rotatably arranged on the platform vehicle and is parallel to the guide rod;

[0031] A screw sleeve, threadably connected to the screw rod and fixed to the operating platform;

[0032] The motor is fixedly arranged on the platform vehicle, and the output end is fixed to the screw rod.

[0033] In one possible implementation, the guardrail includes:

[0034] A guardrail is fixedly arranged on the operating platform, and the guardrail has an opening for workers to get on and off the operating platform;

[0035] A guardrail door is hinged on the guardrail and is used to close the opening.

[0036] In a possible implementation, a protrusion is fixedly provided on the guardrail, a connecting lock piece is hinged on the guardrail door, and a rotation axis of the connecting lock piece and a rotation axis of the guardrail door are perpendicular to each other;

[0037] When the guardrail door closes the opening, the connecting lock piece is clamped on the protrusion to fix the guardrail door.

[0038] The utility model provides a subway air-conditioning disassembly and maintenance platform. Compared with the existing technology, the beneficial effect is that the platform vehicle is arranged on the outside of the train and can move along the train, and the operating platform can be accurately transported to the location of the fresh air device that needs maintenance, avoiding the situation where the staff walk on the roof or work on the edge of danger. The operating platform is raised and lowered by the linear drive assembly, which can smoothly lift the staff to the working height, reducing the risks brought by climbing, unstable standing, etc. when the staff works at height. The guardrail is fixed on the operating platform to enclose a space for accommodating the staff's work, which can prevent the staff from falling from the operating platform due to accidental slips, imbalance, etc. during the operation process, providing reliable protection for the staff and greatly improving the safety of the operation.

[0039] The storage box on the operating platform facilitates temporary storage of the fresh air filter during installation and removal. When removing the fresh air filter, workers can directly insert the removed fresh air filter into the slot, eliminating the need to search for a placement on the roof or damage the fresh air filter due to improper placement. When the fresh air filter needs to be installed, the ejector assembly ejects the fresh air filter from the slot for easy access, making the removal and installation process smoother, improving work efficiency, and reducing work time and labor intensity.

[0047] In order to make the technical problems, technical solutions and beneficial effects to be solved by the present invention more clearly understood, the present invention is further described in detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are only used to explain the present invention and are not intended to limit the present invention.

[0048] See Figure 1 and Figure 2 The utility model provides a subway air conditioner disassembly and maintenance platform, which includes a platform vehicle 1, an operating platform 2, a protective railing 3, a storage box 4, and a plurality of ejection components.

[0049] Among them, the platform car 1 is arranged on the outside of the train and moves along the train, so that the platform car 1 can be docked at the position corresponding to the fresh air device that needs maintenance, avoiding the staff from walking on the roof, and reducing the occurrence of dangerous situations such as slipping and stepping on air when walking on the roof. It should be understood that the platform car 1 is a prior art, and the platform car 1 has a structure for locking the wheels and supporting the body, so that the platform car 1 can ensure the stability of the position when the staff is working. The operating platform 2 is set on the platform car 1 by a linear drive assembly for lifting and lowering, and is used to lift the staff to the working height. The guardrail 3 is fixedly set on the operating platform 2 and encloses a space for accommodating the staff's operation. When the staff is working in this space, even if the body loses balance due to an accident, the guardrail 3 can effectively prevent the staff from falling from the operating platform 2, greatly improving the safety of the operation.

[0050] See Figure 1 and Figure 3 The storage box 4 is fixedly set on the operating platform 2, and a plurality of slots 41 for accommodating the fresh air filter 5 are evenly distributed on the storage box 4 along the length direction, so that the fresh air filter 5 is suitable for vertical insertion in any slot 41. When disassembling the fresh air filter 5, the staff can vertically insert the removed fresh air filter 5 into the slot 41 of the storage box 4 in turn, so that the storage of the fresh air filter 5 is orderly and space-saving. A plurality of ejection components are provided on the storage box 4, and correspond one-to-one to the slots 41, and are used to eject the fresh air filter 5 from the slot 41. When installing the fresh air filter 5, the corresponding ejection component can eject the fresh air filter 5 from the slot 41, and the staff does not need to bend over or take the fresh air filter 5 from other positions with great effort, which reduces the complexity and labor intensity of the operation and improves the work efficiency.

[0051] In some embodiments, see Figure 4The ejection assembly includes an elastic ejection member 61, an elastic locking member 62, and a pressure rod 63. The elastic ejection member 61 is located at the bottom of the slot 41 and has elastic freedom to move vertically, and is used to push the fresh air filter 5 upward and extend from the top of the slot 41. The elastic locking member 62 is located on the side of the elastic ejection member 61 and has elastic freedom to move laterally, and is used to lock the position of the elastic ejection member 61. The pressure rod 63 is vertically slidably arranged on the storage box 4 and abuts against the elastic locking member 62, and is used to push the elastic locking member 62 to move laterally and unlock the elastic ejection member 61.

[0052] When the fresh air filter 5 is inserted into the slot 41, the fresh air filter 5 presses against the upper surface of the elastic ejector 61, compressing the elastic ejector 61 and locking the elastic locking member 62. When the pressure rod 63 moves downward, the elastic locking member 62 unlocks the elastic ejector 61, releasing the compression of the elastic ejector 61 and pushing the fresh air filter 5 upward.

[0053] Specifically, when the fresh air filter 5 is inserted into the slot 41, the fresh air filter 5 presses down on the elastic ejector 61, causing the elastic ejector 61 to be vertically compressed. Simultaneously, the elastic locking member 62 locks the elastic ejector 61 under its elastic action, keeping the elastic ejector 61 in a compressed state, and the fresh air filter 5 is stably stored in the slot 41.

[0054] To access the fresh air filter 5, the operator presses the lever 63, which slides vertically downward. During this process, the lever 63 interacts with the elastic locking member 62, pushing it laterally and releasing the lock on the elastic ejector 61. At this point, the elastic ejector 61 moves upward under its own elastic force, ejecting the fresh air filter 5 from the top of the slot 41. This makes access to the fresh air filter 5 simple and convenient, eliminating the need for the operator to manually reach into the slot 41 to retrieve the filter.

[0055] In some embodiments, see Figure 4 The elastic ejector 61 includes a top block 611 and a first elastic member 612. The top block 611 is vertically slidably disposed on the storage box 4 and is located at the bottom of the slot 41. The first elastic member 612 is disposed between the storage box 4 and the top block 611 to push the top block 611 upward.

[0056] Specifically, when the fresh air filter 5 is inserted into the slot 41, the operator presses down on the fresh air filter 5, causing the top block 611 to move downward, overcoming the elastic force of the first elastic member 612, thereby compressing the first elastic member 612. When the fresh air filter 5 needs to be ejected, the elastic locking member 62 is unlocked, and the first elastic member 612 releases its elastic potential energy, pushing the top block 611 upward.

[0057] Based on the above embodiments, please refer to Figure 4 The elastic ejection member 61 further includes a limiting rod 613 fixedly arranged on the lower surface of the ejection block 611 . The limiting rod 613 is slidably connected to the storage box 4 , and the first elastic member 612 is sleeved on the limiting rod 613 .

[0058] Specifically, the limiting rod 613 guides the vertical movement of the top block 611, ensuring that the top block 611 does not deviate during its upward and downward movement. Simultaneously, the limiting rod 613 provides stable support for the first elastic member 612. During the extension and retraction of the first elastic member 612, the limiting rod 613 prevents the first elastic member 612 from twisting or lateral deformation due to uneven force, thereby ensuring the normal operation and service life of the first elastic member 612.

[0059] In some embodiments, see Figure 4 The elastic locking member 62 includes a locking block 621 and a second elastic member 622. The locking block 621 is laterally slidably mounted on the storage box 4. The second elastic member 622 is disposed between the storage box 4 and the locking block 621 and is configured to push the locking block 621 toward the top block 611. When the top block 611 is retracted into the storage box 4 and the first elastic member 612 is compressed, the locking block 621 is inserted into the top block 611.

[0060] Specifically, when the top block 611 presses down and compresses the first elastic member 612 after the fresh air filter 5 is inserted, the locking block 621 is inserted into the corresponding position on the top block 611 under the action of the second elastic member 622, thereby locking the top block 611. The elastic force ensures that the locking block 621 and the top block 611 are tightly matched, preventing the top block 611 from accidentally moving when it is not necessary to push out the fresh air filter 5. When unlocking is required, the locking block 621 is pushed by the pressure rod 63 to overcome the elastic force of the second elastic member 622 and move laterally, thereby disengaging from the top block 611 and achieving unlocking.

[0061] In some embodiments, see Figure 4 The end of the locking block 621 close to the top block 611 has a guiding inclined surface 6211. When the top block 611 moves downward, the top block 611 abuts against the guiding inclined surface 6211 and pushes the locking block 621 to move laterally, so that the locking block 621 avoids the top block 611.

[0062] When the top block 611 is pressed downward due to the insertion of the fresh air filter 5, it abuts against the guide bevel 6211. As the top block 611 continues to move downward, the locking block 621 moves laterally under the action of the guide bevel 6211, thus avoiding the top block 611 and allowing it to be smoothly pressed down and locked. The guide bevel 6211 facilitates smooth interaction between the locking block 621 and the top block 611, preventing malfunctions caused by direct collision or jamming between the two.

[0063] In some embodiments, see Figure 4 The lower surface of the pressure rod 63 has a pushing inclined surface 631. When the pressure rod 63 moves downward, the pushing inclined surface 631 abuts against the locking block 621 and pushes the locking block 621 to move horizontally, so that the locking block 621 is separated from the pushing block 611.

[0064] When the fresh air filter 5 needs to be removed, the operator presses the pressure rod 63, and the pressure rod 63 moves downward. At this time, the pushing inclined surface 631 will abut against the locking block 621. As the pressure rod 63 continues to move downward, the locking block 621 will move laterally through the interaction between the pushing inclined surface 631 and the locking block 621, thereby disengaging from the ejection block 611 and unlocking the elastic ejection member 61.

[0065] In some embodiments, see Figure 1 and Figure 2 The linear drive assembly includes a guide rod 71, a sliding sleeve 72, a screw 73, a screw sleeve 74 and a motor 75. Among them, the guide rod 71 is vertically fixed on the platform vehicle 1. The sliding sleeve 72 is slidably mounted on the guide rod 71 and is fixed to the operating platform 2. The screw 73 is vertically rotatable and arranged on the platform vehicle 1 and is parallel to the guide rod 71. The screw sleeve 74 is threadedly connected to the screw 73 and is fixed to the operating platform 2. The motor 75 is fixedly arranged on the platform vehicle 1, and the output end is fixed to the screw 73.

[0066] When the motor 75 is started, it drives the screw 73 to rotate, and the screw sleeve 74 is threaded on the screw 73, thereby driving the operating platform 2 to rise or fall along the guide rod 71, thereby raising the operating platform 2 to the desired working height. At the same time, due to the coordination between the screw 73 and the guide rod 71, the operating platform 2 can withstand large loads during the raising and lowering process, ensuring the safety of the workers and the working tools on the operating platform 2.

[0067] In some embodiments, see Figure 1 and Figure 5 The guardrail 3 includes a guardrail 31 and a guardrail door 32. The guardrail 31 is fixedly arranged on the operating platform 2, and the guardrail 31 has an opening for workers to go up and down the operating platform 2. The guardrail door 32 is hinged on the guardrail 31 for closing the opening.

[0068] The opening on the guardrail 31 makes it convenient for workers to enter and exit the operating platform 2, and the guardrail door 32 is hinged on the guardrail 31, so that after the workers enter the operating platform 2, they can close the guardrail door 32, so that the guardrail 3 forms a complete protective space to prevent the workers from falling from the opening due to accidents.

[0069] In some embodiments, see Figure 5A protrusion 33 is fixedly provided on the guardrail 31, and a connecting lock piece 34 is hinged on the guardrail door 32. The rotation axis of the connecting lock piece 34 is perpendicular to the rotation axis of the guardrail door 32. When the guardrail door 32 closes the opening, the connecting lock piece 34 is clamped on the protrusion 33 to fix the guardrail door 32.

[0070] When the guardrail door 32 closes the opening, the connecting lock piece 34 is rotated to engage with the protrusion 33, thereby firmly fixing the guardrail door 32 in the closed position, so that the guardrail 3 forms a complete protective space to prevent workers from accidentally falling from the opening.

[0071] The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. Any modifications, equivalent replacements and improvements made within the spirit and principles of the present invention should be included in the scope of protection of the present invention.
