Description

Technical Field

[0001] The utility model belongs to the technical field of railway freight cars using levers for storage and transportation, and in particular relates to a lever error-proof storage and transportation device universal for multiple models. Background Art

[0002] The levers used in railway vehicles are divided into multiple models according to the type of vehicle and the loading scheme. The main identification basis of each model is the different hole spacings between adjacent holes on the lever. The hole spacing values ​​between some models are close, which is easy to mix and make mistakes. During processing, manufacturing, testing and maintenance, production units need to take effective measures to control and avoid mixing. However, according to past experience, problems are also prone to occur in the storage and transportation links, resulting in the wrong installation of vehicle lever models, such as lever model identification errors that are difficult to detect in time, or different models mixed and misused.

[0003] At present, two methods are usually used to distinguish different models in storage and transportation: one is to manually use measuring tools such as tape measures for re-measurement and identification, and the levers are stacked on forklift material pallets or trolleys for transportation; there are the following defects: during manual re-measurement, omissions or mismeasurements may occur due to the instability of manual operations, and there are no isolation or anti-dumping measures for levers of different models during transportation, which may cause the levers that have been sorted to be mixed again.

[0004] Secondly, after the levers are transported, levers of different models are placed on specified racks for storage. The racks are welded with columns that match the hole spacing, and the levers are put on the columns in sequence to prevent mistakes. However, there are the following defects: the levers must be transported when they are placed on the storage racks from the transport equipment, and the operation process is cumbersome. When placing or removing the levers, each pin hole must pass through the column, and the levers must be transported along the column, which increases the difficulty of transportation. The models and quantities of inventory levers are usually constantly changing. When the fluctuations are large, it is difficult to ensure that the storage space is fully utilized because the applicable storage model on the rack cannot change accordingly. Utility Model Content

[0005] The utility model aims to provide a lever error-proof storage and transportation device that is universal for multiple models, integrating storage and transportation to prevent lever models from being mixed up, and solving the problems of the existing manual distance measurement method for lever model identification causing misdetection, possible mixing during transportation, and the use of storage racks to set up columns that are consistent with lever locating pin holes causing difficulty in transportation and the inability to flexibly adjust storage space.

[0006] To this end, the technical solution adopted by the utility model is: a lever anti-error storage and transportation device that is universal for multiple models, including a supporting frame and anti-error pallets that are detachably arranged on the supporting frame at left and right intervals, the supporting frame as a whole presents a square frame structure, and the bottom of the left and right side beams extend downward to form supporting feet, and the top corners of the left and right side beams are provided with lifting ears, and the front and rear side beams of the supporting frame are horizontally welded with limiting nuts corresponding to the left and right edges of the anti-error pallet, and the limiting nuts are equipped with pallet clamping bolts that can pass through the limiting nuts and tighten the edges of the anti-error pallet, thereby installing the anti-error pallet on the supporting frame, and column mounting tubes with internal threads are welded at front and rear intervals on the upper surface of the anti-error pallet, and the column mounting tubes are all equipped with columns, and when multiple railway truck levers of the same specification are stacked up and down on the anti-error pallet, the locating pin holes of the railway truck levers correspond to the column mounting tubes up and down, and the bottom of the column can pass through the corresponding locating pin holes of the railway truck levers and be inserted into the column mounting tube.

[0007] As a preferred embodiment of the above scheme, four anti-error support plates are used, and the bottom of the column is provided with an external thread that matches the thread of the column installation tube, which is convenient for installation and disassembly of the column and simple to operate.

[0008] It is further preferred that the side end of the clamping block at the top of the support plate clamping bolt can extend into the edge of the anti-error support plate, so as to press the anti-error support plate, and the structural design is reasonable.

[0009] Further preferably, the top of the clamping block of the support plate clamping bolt is a convex arc structure to avoid collision and wear with the railway freight car lever.

[0010] Further preferably, a reinforcing cross beam is provided at the front middle of the supporting chassis to ensure the stability of the structure and reasonable design.

[0011] Beneficial effects of the utility model:

[0012] (1) Compared with the existing method of manually measuring the distance to identify the lever model and using a storage rack to set up a column consistent with the lever positioning pin hole to divide and number the levers, this solution uses a liftable lever error-proof storage and transportation device to achieve the multi-functional integration of preventing mixing and transport storage, assist in confirming the lever model, divide the levers of different models into different areas, and reduce the risk of wrong installation of lever models; realize the integration of error prevention, transportation, and storage functions to reduce handling; the concept is novel, and transportation can be achieved through common equipment such as cranes and forklifts through the lifting ears and support plate structure, which makes transportation convenient and fast, and the design idea is ingenious.

[0013] (2) The anti-mistake pallet can be flexibly disassembled and assembled on the supporting frame, so that the required model of the anti-mistake pallet can be selected according to needs, and the stacked railway truck levers of the required model can be checked through the paired columns. If the lever model is inconsistent with the corresponding pallet model, it cannot be placed. If the models of the stacked levers are inconsistent, the column cannot pass through the locating pin hole on the lever and dock with the locating pin. After the column is installed, it can prevent mixing and dumping. It is flexible to operate and is suitable for the classified storage and transportation of multiple models of railway truck levers.

[0014] (3) Since the anti-mistake pallet is pressed on the supporting frame by the pallet clamping bolts, if it is necessary to replace it with a lever of another type according to storage needs, it is only necessary to loosen the pallet clamping bolts and flexibly replace the anti-mistake pallet, so that the classified storage of railway freight car levers of different specifications can be quickly realized to meet different storage needs and flexibly and efficiently use the storage space.

[0015] In summary, it has the advantages of realizing integrated error-proof transportation and storage functions, preventing mixed stacking, preventing dumping, and making flexible and efficient use of storage space. BRIEF DESCRIPTION OF THE DRAWINGS

[0018] The present invention will be further described below by way of embodiments and in conjunction with the accompanying drawings:

[0019] Combination Figure 1 — Figure 2 As shown, a lever error-proofing storage and transportation device that is universal in multiple models is composed of a supporting base frame 1 and error-proofing pallets 2 that are detachably arranged on the supporting base frame 1 at left and right intervals.

[0020] The supporting frame 1 is in a square frame structure as a whole, and the bottoms of the left and right side beams extend downward to form supporting feet 11, and the top corners of the left and right side beams are provided with lifting ears 12.

[0021] A reinforcing cross beam 13 is provided at the front middle of the supporting frame 1 .

[0022] The front and rear side beams of the supporting frame 1 are horizontally welded with limiting nuts 14 corresponding to the left and right edges of the anti-mistake support plate 2 .

[0023] The limiting nut 14 is equipped with a support plate clamping bolt 5 which can pass through the limiting nut 14 and then clamp the edge of the anti-error support plate 2 , thereby installing the anti-error support plate 2 on the supporting base frame 1 .

[0024] The side end of the clamping block at the top of the support plate clamping bolt 5 can extend into the edge of the anti-error support plate 2, thereby being able to press the anti-error support plate 2.

[0025] The top of the clamping block of the support plate clamping bolt 5 is a convex arc structure.

[0026] Preferably, four error-proofing pallets 2 are used.

[0027] The upper surface of the error-proofing support plate 2 is welded with column mounting cylinders 21 with internal threads at intervals at the front and rear.

[0028] The column mounting cylinders 21 are each equipped with a column 3 .

[0029] The bottom of the column 3 is provided with an external thread that matches the thread of the column mounting tube 21.

[0030] When multiple railway truck levers 4 of the same specification are stacked up and down at corresponding positions on the anti-mistake support plate 2, the positioning pin holes of the railway truck levers 4 correspond to the column mounting tubes 21 up and down, and the bottom of the column 3 can pass through the corresponding positioning pin holes of the railway truck levers 4 and then be inserted into the column mounting tube 21.

[0031] First, store the lever in an unloaded state; the locating pin hole of the railway truck lever 4 is aligned with the column mounting tube 21 of the anti-mistake pallet 2, and the column mounting tube 21 passes through the locating pin hole of the railway truck lever 4 to achieve preliminary positioning. If it cannot pass through, it means that there is a deviation in the spacing size of the locating pin holes of the railway truck lever 4, and the specifications of the railway truck lever 4 should be rechecked.

[0032] Then place the column 3; when there are multiple railway truck levers 4 stacked on the anti-error pallet 2, use the column 3 to insert it into the positioning pin hole of the railway truck lever 4, and the bottom end of the column 3 can pass through each lever in turn and be fixed to the anti-error pallet 2 by threaded connection, which means that the hole distance size of each lever is consistent.

[0033] After installation is completed, the device is transported by lever; the lifting lug 12 on the supporting frame 1 is hung with a sling and then lifted by a crane for transportation, or the entire device is lifted by a forklift for transportation.

[0034] Finally, if it is necessary to replace the applicable lever specifications; rotate the pallet clamping bolt 5 so that the error-proofing pallet 2 can be removed from the supporting base frame 1; after replacing other types of error-proofing pallets 2 and placing them on the supporting base frame 1, rotate the pallet clamping bolt 5 to press the rotating error-proofing pallet 2 on the supporting base frame 1 to complete the replacement.
