Description

Technical Field

[0001] The utility model relates to the technical field of maintenance of subway trains, in particular to a special tool for checking the lateral stop clearance of subway electric passenger cars. Background Technique

[0002] The maintenance work of rail transit vehicles can timely detect and eliminate potential hazards and problems of the vehicles, ensure the safe operation of the vehicles, reduce potential accident hazards, and ensure the travel safety of passengers. At present, the traditional method for checking the lateral stop clearance is to actually measure the value of the lateral stop clearance using a steel straightedge or a tape measure, and then verify whether this value is within the specified range after obtaining the accurate value of the lateral stop clearance, so as to judge whether the lateral stop clearance meets the technical requirements.

[0003] However, there are many drawbacks in actual operation. First of all, since there are a large number of lateral stop clearances to be checked, the process of measuring and reading using a steel straightedge or a tape measure takes a long time, reducing the inspection efficiency. Secondly, usually the lateral stop is located at a position slightly above the middle of the bogie in the running gear system, and the operating space is very small. When the inspection personnel check under the vehicle, they need to extend the measuring tool into this narrow space for a certain distance to reach the position of the lateral stop clearance for measurement, which is very inconvenient to operate. Finally, due to the error in manual measurement, there is a certain misjudgment when verifying whether the measured data meets the technical requirements after obtaining the measurement data, which affects the inspection result and reduces the inspection accuracy. Content of the Utility Model

[0004] The purpose of the utility model is to provide a special tool for checking the lateral stop clearance of subway electric passenger cars. When checking the special tool for the lateral stop clearance, there is no process of directly measuring the lateral stop clearance using a measuring tool, nor is it necessary to verify the measurement data, so there is no possibility of misjudgment. And in order to facilitate the operation of the operator, a detachable extended handle is specially added to the special tool for checking the lateral stop clearance, so that the operator can use the special tool to quickly reach near the lateral stop clearance to be checked, so as to solve the problems raised in the above background technique.

[0005] To achieve the above purpose, the utility model provides the following technical solution: A special tool for checking the lateral stop clearance of subway electric passenger cars, including a special tool main body and a handle. A groove is opened at the bottom of the special tool main body, one end of the handle is inserted into the groove, and an adsorption mechanism for preventing the handle from separating from the special tool main body is arranged at the contact position between the handle and the groove. Digital marks and arrow marks are respectively arranged on two surfaces of the special tool.

[0006] Preferably, the adsorption mechanism includes a first neodymium iron boron magnet and a second neodymium iron boron magnet. The first neodymium iron boron magnet is arranged in the inner cavity of the groove. A clamping groove is formed at one end of the handle inserted into the groove. The second neodymium iron boron magnet is arranged in the clamping groove. The first neodymium iron boron magnet and the second neodymium iron boron magnet are magnetically adsorbed and connected to each other.

[0007] Preferably, one end of the handle away from the groove is thickened. A through hole is formed in the thickened end of the handle, and a pull rope is wound in the inner cavity of the through hole.

[0008] Preferably, the groove is hexagonal in shape, and the handle has the same shape as the groove.

[0009] Preferably, the edges of the special tool body are chamfered, and the width between opposite sides of the groove is set to 7 mm.

[0010] Compared with the prior art, the beneficial effects of the present utility model are as follows:

[0011] The present utility model provides a special tool for checking the lateral stop gap of a subway electric multiple unit. By designing a groove at the bottom of the special tool body and then cooperating with a detachable extended handle, after inserting the handle into the groove, the operator can operate while standing on the side of the car body underframe. There is no need to use traditional tools such as a steel straightedge or a tape measure to measure specific values. Just insert the special tool body into the lateral stop gap for inspection, which greatly reduces the inspection time and improves the inspection accuracy. Inserting the special tool body into the lateral stop gap through the handle avoids the operation of the operator in a narrow space, and improves the operation efficiency and safety of the operator.

[0012] The present utility model provides a special tool for checking the lateral stop gap of a subway electric multiple unit. By arranging an adsorption mechanism at the contact position between the handle and the groove, through the cooperation of the first neodymium iron boron magnet and the second neodymium iron boron magnet in the adsorption mechanism, when the handle is inserted into the groove, the strong suction force between the first neodymium iron boron magnet and the second neodymium iron boron magnet ensures that the special tool body will not disconnect from the handle when inserted into the lateral stop gap, thus preventing the situation of dropping.

Specific embodiments

[0020] Next, the technical solutions in the embodiments of the present utility model will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present utility model. Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all the embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative work shall fall within the protection scope of the present utility model.

[0021] The present utility model provides a special tool for checking the lateral stop gap of a subway electric passenger car as Figures 1 to 6 shown, which includes a main body 1 of the special tool and a handle 2. A groove 3 is opened at the bottom of the main body 1 of the special tool. One end of the handle 2 is inserted into the groove 3. An adsorption mechanism 4 for preventing the handle 2 from separating from the main body 1 of the special tool is provided at the contact position between the handle 2 and the groove 3. Digital marks 5 and arrow marks 6 are respectively provided on two of the surfaces of the special tool. The shape of the groove 3 is hexagonal, and the shape of the handle 2 is the same as that of the groove 3. By designing the groove 3 at the bottom of the main body 1 of the special tool and then cooperating with the detachable extended handle 2, after inserting the handle 2 into the groove 3, the operator can operate while standing on the side of the bottom of the vehicle, without directly inserting the main body 1 of the special tool into the lateral stop gap by hand. Insert the main body 1 of the special tool into the lateral stop gap through the handle 2, thereby avoiding the operation of the operator in a narrow space, improving the operation efficiency and safety of the operator, and the adsorption mechanism 4 provided at the connection between the special tool and the handle 2 can strengthen the firmness between the handle 2 and the main body 1 of the special tool, preventing the main body 1 of the special tool from falling, and the digital marks 5 marked on the main body 1 of the special tool are 12 mm and 18 mm respectively, and the arrow marks 6 are set at the same time, which can ensure that the operator confirms which side is 12 mm and which side is 18 mm before use to prevent the insertion direction from being wrong.

[0022] The adsorption mechanism 4 includes a first neodymium iron boron magnet 41 and a second neodymium iron boron magnet 42. The first neodymium iron boron magnet 41 is arranged in the inner cavity of the groove 3. A clamping groove 43 is formed at one end of the handle 2 inserted into the groove 3. The second neodymium iron boron magnet 42 is arranged in the clamping groove 43. The first neodymium iron boron magnet 41 and the second neodymium iron boron magnet 42 are magnetically adsorbed and connected. By arranging the adsorption mechanism 4 at the contact position between the handle 2 and the groove 3, through the cooperation of the first neodymium iron boron magnet 41 and the second neodymium iron boron magnet 42 in the adsorption mechanism 4, when the handle 2 is inserted into the groove 3, the strong suction force between the first neodymium iron boron magnet 41 and the second neodymium iron boron magnet 42 ensures that the special tool body 1 will not disconnect from the handle 2 when inserted into the lateral stop gap, thus preventing the situation of dropping.

[0023] One end of the handle 2 away from the groove 3 is thickened. A through hole 7 is formed in the thickened end of the handle 2. A pull rope 8 is wound in the inner cavity of the through hole 7. One end of the handle 2 is thickened. Through the thickening design, the holding feel can be improved and an anti-slip design can be realized to prevent the operator from inserting the end without the second neodymium iron boron magnet 42 into the groove 3.

[0024] The edges of the special tool body 1 are chamfered. Through the chamfering design, it is prevented that the hands of the operator are cut by the sharp edges during the operation of the special tool body 1. The width of the opposite sides of the groove 3 is set to 7 mm.

[0025] During specific use, the lengthened handle 2 is inserted into the groove 3. The operator can stand on the side of the vehicle bottom for operation. The special tool body 1 is inserted into the lateral stop gap through the handle 2. Therefore, there is no need to insert the above-mentioned body into the lateral stop gap by hand, which greatly reduces the inspection time, improves the inspection accuracy, and avoids the operation of the operator in a narrow space, improving the operation efficiency and safety of the operator. At the same time, during the process of inserting the special tool body 1, the operator can shell according to the digital signs 5 on the special tool body 1, which are 12 mm and 18 mm respectively, and cooperate with the arrow sign 6, so as to correctly insert the professional tool into the lateral stop gap to prevent the operator from inserting in the wrong direction. At the same time, an adsorption mechanism 4 is arranged at the connection between the handle 2 and the professional tool body. The strong suction force between the first neodymium iron boron magnet 41 and the second neodymium iron boron magnet 42 in the adsorption mechanism 4 ensures that the special tool body 1 will not disconnect from the handle 2 when inserted into the lateral stop gap, thus preventing the situation of dropping.
