Description

Technical Field

[0001] The utility model belongs to the technical field of subway air-conditioning transportation, and more specifically, relates to a subway air-conditioning transportation tooling. Background Art

[0002] In modern urban rail transit, the subway has become an important public transportation tool due to its large capacity and high efficiency. Subway trains often run through city centers, with a high proportion of these routes being underground. Underground tunnels are relatively confined, making it difficult for subway trains to rely on tunnel ventilation for extended periods of time. Air circulation within subway trains relies on air conditioning units for ventilation and filtration. These units travel long distances and carry heavy loads, making them prone to failure and damage in hot weather. These units then need to be removed from the subway trains and transported back to the factory for repair and replacement.

[0003] Subway train air conditioning units are constructed of irregularly shaped stainless steel boxes. These units are heavy and bulky, making them difficult to stack for storage or transportation. Current transport operations require specialized transport jigs to effectively transfer these units. Existing transport jigs for subway train air conditioning units are often crudely designed and bulky, as they must accommodate their large size and weight. These bulky jigs occupy significant factory floor space when stored, resulting in significant waste of space resources. Utility Model Content

[0004] The purpose of the utility model is to provide a subway air-conditioning transport tooling, aiming to reduce the space occupied when the transport tooling is stored.

[0005] To achieve the above-mentioned purpose, the technical solution adopted by the present invention is to provide a subway air-conditioning transport tool, comprising:

[0006] The transport rack comprises a bottom frame, two long frames hinged on both sides of the bottom frame, and two short frames; the long frames can be rotated to a use state perpendicular to the bottom frame and a storage state parallel to the bottom frame; when the two long frames are in use, the two short frames are vertically inserted between the two long frames and abut against the bottom frame;

[0007] a hanger for fixing the subway air conditioner; when the two long frames are in use, the hanger is overlapped on the upper surfaces of the two long frames and is fixed to the two long frames by fasteners, so that the hanger and the transport frame form an internal space for accommodating the subway air conditioner; and

[0008] Two locking components are arranged on the bottom frame and correspond one to one with the short frames. The locking components are used to fix the short frames.

[0009] In one possible implementation, the locking assembly includes:

[0010] A double-headed screw is horizontally rotatably arranged on the bottom frame, and half of the threaded portion is a left-hand thread and the other half is a right-hand thread;

[0011] Two locking blocks are slidably disposed on the bottom frame and are threadedly connected to the left-hand thread and the right-hand thread respectively;

[0012] The lower surfaces of the two short frames are each provided with a first locking groove suitable for connecting with the locking block. When the short frame abuts against the bottom frame, the locking block can be inserted into the first locking groove to form upper and lower limit positions for the short frame.

[0013] In one possible implementation, a second locking groove suitable for connecting with the locking block is provided on one side of the two long frames close to each other. When the two long frames are in the storage state, the locking block can be inserted into the second locking groove to form upper and lower limits for the two long frames.

[0014] In a possible implementation, the locking assembly further includes a guide rod fixedly disposed on the bottom frame, wherein the guide rod is parallel to the double-headed screw and is slidably connected to the two locking blocks.

[0015] In a possible implementation, a rotating handle is fixedly provided on the circumferential surface of the double-headed screw, and the rotating handle extends from the lower surface of the bottom frame.

[0016] In a possible implementation, a flange is vertically fixedly provided on a side of the short frame close to the long frame, and a groove suitable for plugging with the flange is formed on a side of the long frame close to the short frame.

[0017] In a possible implementation, a positioning plate is fixedly provided on the upper surface of the long frame. When the hanger is overlapped on the long frame, the positioning plate abuts against the outer peripheral wall of the hanger to form a horizontal limit for the hanger.

[0018] In a possible implementation, the positioning plate has a guide slope; when the hanger is overlapped on the long frame from top to bottom, the hanger abuts against the guide slope and moves along the guide slope to align the hanger with the transport rack.

[0019] In one possible implementation, legs are fixedly provided on the lower surface of the bottom frame, and positioning pins are fixedly provided on the upper surface of the long frame. When the two long frames are in use, multiple transport racks are stacked up and down, and the positioning pins can be aligned and plugged into the legs.

[0020] In a possible implementation, the inner side of each of the two long frames is fixedly provided with a protective pad.

[0021] Compared with the prior art, the subway air conditioner transportation tool has the beneficial effects that when the transportation tool is not used, the short frame and the hanger can be separately disassembled and stacked for storage, the long frame can be rotated to a storage state of parallel adhesion with the bottom frame, and multiple transportation tools in the storage state can be closely arranged for storage, thereby saving a large amount of factory area.

DETAILED DESCRIPTION

[0029] 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.

[0030] See Figure 1 The utility model provides a subway air-conditioning transport tooling, which includes a transport frame 1, a hanger 2 and two locking components.

[0031] See Figure 1 、 Figure 2 and Figure 3 The transport rack 1 includes a base frame 11, two long frames 12 hinged on either side of the base frame 11, and two short frames 13. The long frames 12 can be rotated to a position perpendicular to the base frame 11 for use and rotated to a position parallel to the base frame 11 for storage. When the two long frames 12 are in use, the two short frames 13 are vertically inserted between the two long frames 12 and abut against the base frame 11.

[0032] When the transport jig is not in use, the short frame 13 is removed, and the long frame 12 is rotated to a storage state parallel to the base frame 11, so that the long frame 12 and the base frame 11 constitute a planar frame structure, which greatly reduces the occupied space of the transport jig as a whole. In the storage state, multiple transport jigs can be closely arranged and stored, which can save a lot of factory area compared to traditional large-scale fixed structure transport jigs. At the same time, multiple disassembled short frames 13 can also be closely arranged and stored, which greatly reduces the occupied space. When the transport jig is needed, the long frame 12 is rotated to a use state perpendicular to the base frame 11, and then the short frame 13 is vertically plugged between the two long frames 12 and abutted against the base frame 11, and the transport rack 1 can be quickly built. The construction method is simple to operate and does not require complicated tools and a large amount of manpower.

[0033] See Figure 1 Hanger 2 is used to secure the subway air conditioner. When the two long frames 12 are in use, hanger 2 overlaps the upper surfaces of the two long frames 12 and is secured to the two long frames 12 via fasteners, so that hanger 2 and transport rack 1 form an internal space for accommodating the subway air conditioner. Two locking assemblies are provided on the bottom frame 11, corresponding one-to-one with the short frames 13, and are used to secure the short frames 13.

[0034] When transporting the air conditioning unit, bolts are passed through the mounting holes on the air conditioning unit and the mounting holes on the hanger 2, and then nuts are connected to secure the hanger 2 to the air conditioning unit. The hanger 2, along with the air conditioning unit, is then lifted using a forklift or overhead crane and placed inside the transport rack 1, ensuring that there is no contact between the outer wall of the air conditioning unit and the inner wall of the transport rack 1. The hanger 2 is overlapped on the upper surface of the transport rack 1, and the hanger 2 and transport rack 1 are secured together with bolts and nuts to ensure that the hanger 2 does not move relative to the transport rack 1 during transportation.

[0035] In some embodiments, see Figure 4 The locking assembly includes a double-headed screw 31 and two locking blocks 32. The double-headed screw 31 is horizontally rotatably mounted on the bottom frame 11, with half of the threaded portion being left-handed and the other half being right-handed. The two locking blocks 32 are slidably mounted on the bottom frame 11 and are threadedly connected to the left-handed and right-handed threads, respectively. A first locking groove 131 is formed on the lower surface of each of the two short frames 13, which is suitable for connecting with the locking blocks 32. When the short frames 13 abut against the bottom frame 11, the locking blocks 32 can be inserted into the first locking groove 131 to form upper and lower limit limits for the short frames 13.

[0036] When the double-headed screw 31 is rotated, the two locking blocks 32 will move simultaneously in opposite or opposite directions due to the action of the threads. First, the position of the locking blocks 32 is adjusted so that after the short frame 13 abuts the bottom frame 11, the locking blocks 32 can be inserted into the first locking grooves 131 on the lower surface of the short frame 13. Then, the double-headed screw 31 is rotated so that the locking blocks 32 are engaged in the first locking grooves 131, thereby forming upper and lower limit stops for the short frame 13, achieving a secure locking of the short frame 13, effectively preventing the short frame 13 from shifting up and down due to vibration or other external forces during transportation, and enhancing the stability and reliability of the transport rack 1 structure.

[0037] Based on the above embodiments, please refer to Figure 3 The two long frames 12 are each provided with a second locking groove 121 suitable for connecting with the locking block 32 on one side close to each other. When the two long frames 12 are in the storage state, the locking block 32 can be inserted into the second locking groove 121 to form upper and lower limits for the two long frames 12.

[0038] The locking assembly not only locks the short frames 13 during transport, but also functions when the long frames 12 are in the stowed state. When the two long frames 12 are stowed, the locking blocks 32 engage the second locking slots 121 on the long frames 12, creating upper and lower position limits for the two long frames 12. When the transport tooling is stored, the long frames 12 can be easily secured by rotating the stud screws 31, preventing them from expanding or deforming during storage due to accidental collisions or other factors. This protects the structural integrity of the transport tooling, extends its service life, and further enhances the safety and stability of on-site storage.

[0039] In some embodiments, see Figure 4 The locking assembly further includes a guide rod 33 fixed to the base frame 11. The guide rod 33 is parallel to the stud screw 31 and is slidably connected to the two locking blocks 32. As the locking blocks 32 move with the rotation of the stud screw 31, the guide rod 33 provides a stable guide for the locking blocks 32, ensuring that the locking blocks 32 move smoothly in a straight line without deflection or skew.

[0040] In some embodiments, see Figure 4 A handle 34 is fixedly mounted on the circumferential surface of the double-ended screw 31, extending from the lower surface of the base frame 11. Positioning the handle 34 on the lower surface of the base frame 11 conceals it, reducing the possibility of accidental contact or misoperation. Furthermore, the handle 34 extending from the lower surface of the base frame 11 provides a convenient operation method for the operator. To lock or unlock the short frame 13 or the long frame 12, the operator simply pushes the handle 34 from under the base frame 11 to easily rotate the double-ended screw 31, thereby controlling the movement of the locking block 32.

[0041] In some embodiments, see Figure 5 A flange 132 is vertically fixedly provided on the side of the short frame 13 adjacent to the long frame 12, and a groove 124 is provided on the side of the long frame 12 adjacent to the short frame 13, adapted to engage with the flange 132. During assembly of the transport tooling, the cooperation between the flange 132 and the groove 124 guides the short frame 13 accurately into position between the two long frames 12, preventing the short frame 13 from shifting or tilting during insertion and ensuring the structural integrity of the transport rack 1. Furthermore, during transport, the tight fit between the flange 132 and the groove 124 can withstand certain lateral forces, preventing the short frame 13 from separating from the long frame 12 due to external forces, further enhancing the stability and reliability of the transport rack 1.

[0042] In some embodiments, see Figure 5 A positioning plate 123 is fixedly provided on the upper surface of the long frame 12. When the hanger 2 is overlapped on the long frame 12, the positioning plate 123 abuts against the outer wall of the hanger 2 to form a horizontal limit for the hanger 2.

[0043] When the subway air conditioner is secured to hanger 2 and placed on transport rack 1, positioning plate 123 prevents hanger 2 from shifting horizontally, ensuring the air conditioner unit remains in the preset position on transport rack 1, facilitating balance control and ensuring safety during transportation. Furthermore, the horizontal position limit of positioning plate 123 helps protect the air conditioner unit during transportation, preventing collision or friction between the air conditioner unit and components of transport rack 1 due to movement of hanger 2.

[0044] In some embodiments, see Figure 5 The positioning plate 123 has a guide slope 1231. When the hanger 2 is overlapped on the long frame 12 from top to bottom, the hanger 2 abuts against the guide slope 1231 and moves along the guide slope 1231 to align the hanger 2 with the transport frame 1.

[0045] When installing the hanger 2 on the transport rack 1, even if the operator makes some errors when placing the hanger 2, the guide slope 1231 can guide the hanger 2 to gradually adjust its position so that it can be accurately moved to the preset position of the transport rack 1. This guiding function improves the convenience and accuracy of the installation of the hanger 2, reduces the transportation safety hazards caused by improper installation of the hanger 2, and also reduces the operating skills required of the operator, thereby improving the ease of use of the transport tooling.

[0046] In some embodiments, see Figure 1 and 5 The lower surface of the bottom frame 11 is fixedly provided with support legs 111, and the upper surface of the long frame 12 is fixedly provided with positioning pins 122. When the two long frames 12 are in use, multiple transport racks 1 are stacked up and down, and the positioning pins 122 can be aligned and plugged with the support legs 111.

[0047] When transporting multiple air conditioning units, the transport jigs can be stacked, reducing the space required for transport and improving transport efficiency. Furthermore, the precise alignment of the locating pins 122 with the legs 111 ensures stacking stability, preventing the transport jigs from tipping over or shifting during stacking, thereby improving safety during storage and transportation.

[0048] In some embodiments, see Figure 1 The inner sides of the two long frames 12 are fixedly provided with protective pads 125. The protective pads 125 protect the air conditioning unit. When the air conditioning unit is placed in the transport rack 1, the protective pads 125 can prevent the air conditioning unit from accidentally contacting the transport rack 1 and causing scratches or collisions.

[0049] In summary, the utility model provides a subway air-conditioning transport tooling, which, compared with the prior art, is capable of detaching the short frame 13 and the hanger 2 separately for stacking and storage when the transport tooling is not in use, while the long frame 12 can be rotated to a storage state parallel to the bottom frame 11. Multiple transport tools in the storage state can be closely arranged and stored, saving a large amount of factory space. When the transport tooling is needed, the long frame 12 is rotated to a use state perpendicular to the bottom frame 11, the short frame 13 is vertically inserted between the two long frames 12 and abutted against the bottom frame 11, and then the short frame 13 is fixed using a locking assembly, and the transport rack 1 can be quickly erected.

[0050] 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.
