Description

Technical Field

[0001] This invention relates to the field of flaw detection equipment for wheelsets in railway locomotive pits, and particularly to a locking mechanism for a transfer device of flaw detection equipment for railway locomotive pits. Background Technology

[0002] Wheel flaw detection is a crucial part of the daily maintenance and repair of locomotives. This process is usually carried out in a dedicated maintenance pit to ensure the accuracy and comprehensiveness of the inspection. However, when a flaw detection operation is completed and it is necessary to move the flaw detection equipment to another maintenance pit to continue other operations, a key issue arises: how to move these delicate and relatively bulky devices safely and efficiently.

[0003] To solve this problem, a special transfer device is usually used. This transfer device is ingeniously designed to accommodate flaw detection equipment of different sizes and weights, ensuring its stability and safety during the transfer process. However, relying solely on the transfer device itself is not enough to completely guarantee the absolute safety of the equipment. If the equipment is not properly secured and locked on the transfer device during the transfer process, it is very likely to be displaced or slipped due to vibration, bumps, or human error.

[0004] If the equipment shifts or slides, the consequences will be disastrous. First, the equipment may be damaged by colliding with the edge of the trench or other hard objects. This will not only affect the effectiveness of subsequent flaw detection operations, but may also lead to high maintenance costs and longer downtime. More seriously, if the equipment slips and hits workers in the trench, it may cause personal injury or death, resulting in irreparable losses and legal liabilities for the company. Summary of the Invention

[0005] This invention provides a locking mechanism for a transfer device of railway locomotive trench flaw detection equipment, which solves the problem mentioned in the background art that if the railway locomotive trench flaw detection equipment is not properly fixed and locked on the transfer device during the transfer process, it is very likely to be displaced or slipped due to vibration, bumps or human error.

[0006] This invention provides a locking mechanism for a transfer device of flaw detection equipment in a railway locomotive trench, comprising:

[0007] A docking base is installed on a transfer device. A load base is snapped onto the docking base, and the load base is connected to the bottom of the railway locomotive trench flaw detection equipment.

[0008] An electric locking device is provided at the position of the docking base corresponding to the position of the load base, and a locking pin is provided on the electric locking device. A fixing hole is provided at the position of the load base corresponding to the position of the locking pin.

[0009] A sensor is mounted on the docking base and is electrically connected to the electric locking device;

[0010] The load base is fixedly connected to the bottom of the railway locomotive trench flaw detection equipment. When the flaw detection equipment needs to be placed on the transfer device, the sensor on the docking structure of the transfer device will detect the docking status between the load base and the docking structure. When the load base reaches the docking zero position, it contacts the sensor. At this time, the electric locking device is activated, pushing out the locking pin and inserting it through the load base, thereby fixing the flaw detection equipment to the transfer device, and then transferring the equipment.

[0011] The two sets of docking bases can clamp the load base. When the load base is engaged between the two sets of docking bases, the docking bases have a certain range of correction for the lateral offset of the load base, allowing the load to be more accurately and conveniently combined with the docking fixing device.

[0012] Both sets of docking bases have beveled surfaces on the upper end faces of the side walls that are close to each other.

[0013] The beveled design maximizes the opening size at the upper end of the two sets of docking bases, making it easier for the load base to be inserted into the middle position of the two sets of docking bases, allowing the load to be more accurately and conveniently combined with the docking and fixing device.

[0014] Both sets of docking bases are provided with matching load support blocks on the same side wall, and both sets of load support blocks are provided with threaded holes.

[0015] The two sets of docking bases have matching threaded holes at the positions of the threaded holes on the load support blocks. The fixing bolts pass through the threaded holes and are screwed into the threaded holes on the docking bases. The load support blocks are fixed to the two side walls of the docking bases by the fixing bolts.

[0016] When the load base is inserted into the middle position of the two sets of docking bases, the load base has a large weight, so the spring and fixing pin alone cannot support the load for a long time. However, this structure can effectively support the weight of the load base, making it the main load-bearing point in the transfer device.

[0017] The sensor is fixedly installed at the center of the two sets of docking bases.

[0018] The two sets of docking bases are provided with through holes at the positions corresponding to the electric locking devices.

[0019] A matching locking pin is fixedly installed at the output end of the electric locking device at the position corresponding to the through hole.

[0020] The locking pin is inserted into the through hole at one end away from the electric locking device, and the size of the locking pin matches the size of the through hole.

[0021] When the load base is inserted into the middle position of the two sets of docking bases, the docking groove on the lower end face of the load base will engage with the docking block.

[0022] When the lower end face of the load base comes into contact with the sensor, the sensor sends a signal. At this time, the electric locking device receives the signal and pushes out the locking pin. One end of the locking pin passes through the through hole and is inserted into the interior of the load base, so that the load base is completely fixed and prevents the load base from moving.

[0023] A matching pressure spring is fixedly installed at the center position of the two sets of docking bases, corresponding to the position of the sensor.

[0024] The pressure spring is sleeved on the outside of the sensor, and a matching mating block is fixedly provided on the upper end face of the pressure spring.

[0025] When the load base moves downward, it will compress the pressure spring through the docking block. When there are some errors in the docking of the load base, the pressure spring can provide some compensation. In addition, when the load base docks, there will be a certain impact force between the load base and the docking device. The pressure spring can reduce the impact force on the equipment.

[0026] The load base has a docking groove at the position corresponding to the docking block.

[0027] When the load base is inserted into the middle position of the two sets of docking bases, the docking groove opened on the lower end face of the load base will engage with the docking block. Through the cooperation of the docking block, the vertical sliding and displacement of the equipment is prevented.

[0028] The docking block has a clearance hole at the position corresponding to the sensor, and the size of the clearance hole matches the size of the sensor.

[0029] When the load base moves downward, it will compress the pressure spring through the docking block. When the pressure spring is compressed, the pressure spring moves downward relative to the sensor. At this time, the sensor, with the cooperation of the clearance hole, extends to the top of the docking block, so that the load base can contact it. When there are some errors in the docking of the load base, the pressure spring can provide some compensation. Furthermore, when the load base docks, there will be a certain impact force between the load base and the docking device. The pressure spring can reduce the impact force on the equipment.

[0030] The height of the sensor is matched with the height of the load support block.

[0031] When the load base moves downward, it will compress the pressure spring through the docking block. When the pressure spring is compressed, the pressure spring moves downward relative to the sensor. At this time, the sensor, with the cooperation of the clearance hole, extends to the top of the docking block, so that the load base can contact it.

[0032] When the lower end face of the load base comes into contact with the sensor, the sensor sends a signal. At this time, the electric locking device receives the signal and pushes out the locking pin. One end of the locking pin passes through the through hole and is inserted into the interior of the load base, so that the load base is completely fixed and prevents the load base from moving.

[0033] Furthermore, when the lower end face of the load base contacts the sensor, the lower end face of the load base also contacts the load support block. The load support block effectively supports the weight of the load base and is the main load-bearing point in the transfer device.

[0034] Compared with the prior art, the advantages of the present invention are as follows:

[0035] The load base can be directly inserted between the two sets of docking bases to fix the railway locomotive trench flaw detection equipment and restrict its horizontal and vertical movement.

[0036] The load base is inserted between two sets of docking bases to fix the railway locomotive trench flaw detection equipment. Then, the load base is fixed by using a sensor and an electric locking pin.

[0037] When the flaw detection equipment is ready to be transported, the positioning device on the equipment is used to align the equipment with the locking mechanism. Then, the locking mechanism on the transport device begins to dock with the bottom of the flaw detection equipment. The bottom of the flaw detection equipment has a corresponding notch. When the flaw detection equipment docks, the docking block in the locking structure first connects with the bottom slot. Then, the spring inside the docking device is compressed. At this time, the impact force of the equipment is reduced. When the spring is compressed to a certain extent, the sensor will sense that the equipment has docked in place. At this time, the locking pin in the structure extends to fix the flaw detection equipment. The docking and locking of the transport device is completed, and the transport of the flaw detection equipment begins.

[0038] This docking and fixing device uses a combination of mechanical adaptive technology and electronic induction technology to achieve fixing and locking. It utilizes the mechanical locking structure and spring performance, combined with sensors and various electronic control technologies, resulting in higher stability and reliability.

[0052] This invention provides a locking mechanism for a transfer device of flaw detection equipment in a railway locomotive trench, comprising:

[0053] A docking base 1 is installed on a transfer device, and a load base 8 is snapped onto the docking base 1. The load base 8 is connected to the bottom of the railway locomotive trench flaw detection equipment.

[0054] An electric locking device 2 is provided at the position of the docking base 1 corresponding to the load base 8, and a locking pin 4 is provided on the electric locking device 2. The load base 8 is provided with a fixing hole at the position of the locking pin 4 for locking the load base 8.

[0055] Sensor 6 is mounted on docking base 1 and is electrically connected to electric locking device 2.

[0056] The load base 8 is fixedly connected to the bottom of the flaw detection equipment. When the flaw detection equipment needs to be placed on the transfer device, the load base 8 is snapped onto the docking base 1, thereby fixing the flaw detection equipment to the transfer device, and then the equipment is transferred.

[0057] The two sets of docking bases 1 can clamp the load base 8. When the load base 8 is inserted between the two sets of docking bases 1, the docking base 1 has a certain range of correction for the lateral offset of the load base 8, so that the load base 8 can be more accurately and conveniently combined with the docking structure.

[0058] The upper surface of the side wall of the two sets of docking bases 1 that are close to each other is provided with a beveled surface 12;

[0059] The beveled surface 12 maximizes the opening size at the upper end of the two sets of docking bases 1, making it easier for the load base 8 to be inserted into the middle position of the two sets of docking bases 1, and allowing the load base 8 to be more accurately and conveniently combined with the docking structure.

[0060] Both sets of docking bases 1 are provided with matching load support blocks 7 on the same side wall, and both sets of load support blocks 7 are provided with threaded holes 9.

[0061] The two sets of docking bases 1 have matching threaded holes at the positions of the threaded holes 9 on the corresponding load support blocks 7 on the side walls. The fixing bolts pass through the threaded holes 9 and are screwed into the threaded holes on the docking bases 1. The load support blocks 7 are fixed to the two side walls of the docking bases 1 by the fixing bolts.

[0062] When the load base 8 is inserted into the middle position of the two sets of docking bases 1, the load base 8 has a large weight, so the pressure spring 5 and locking pin 4 alone cannot support the load base 8 for a long time. However, this structure can effectively support the weight of the load base 8, so this structure is the main load-bearing point in the transfer device.

[0063] Sensor 6 is fixedly installed at the center of the two sets of docking bases 1;

[0064] Two sets of docking bases 1 are provided with through holes 10 at the positions of the corresponding electric locking devices 2;

[0065] A matching locking pin 4 is fixedly installed at the corresponding through hole 10 position of the output end of the electric locking device 2;

[0066] The end of the locking pin 4 away from the electric locking device 2 is inserted into the interior of the through hole 10, and the size of the locking pin 4 matches the internal size of the through hole 10.

[0067] When the load base 8 is inserted into the middle position of the two sets of docking bases 1, the docking groove 13 opened on the lower end face of the load base 8 will be snapped onto the docking block 3.

[0068] When the lower end face of the load base 8 comes into contact with the sensor 6, the sensor 6 sends a signal. At this time, the electric locking device 2 receives the signal and pushes out the locking pin 4. One end of the locking pin 4 passes through the through hole 10 and is inserted into the interior of the load base 8, so that the load base 8 is completely fixed and prevents the load base 8 from moving.

[0069] A matching pressure spring 5 is fixedly installed at the center position of the two sets of docking bases 1, corresponding to the position of the sensor 6;

[0070] The pressure spring 5 is sleeved on the outside of the sensor 6, and a matching mating block 3 is fixedly provided on the upper end face of the pressure spring 5;

[0071] When the load base 8 moves downward, it will compress the pressure spring 5 through the docking block 3. When there are some errors in the docking of the load base 8, the pressure spring 5 can provide some compensation. In addition, when the load base 8 docks, there will be a certain impact force between the load base 8 and the docking device. The pressure spring 5 can reduce the impact force of the equipment.

[0072] A docking groove 13 is provided at the position of the corresponding docking block 3 of the load base 8;

[0073] When the load base 8 is inserted into the middle position of the two sets of docking bases 1, the docking groove 13 opened on the lower end face of the load base 8 will be engaged with the docking block 3. Through the cooperation of the docking block 3, the vertical sliding and displacement of the equipment is prevented.

[0074] A clearance hole 11 is provided at the position of the corresponding sensor 6 in the docking block 3, and the size of the clearance hole 11 matches the size of the sensor 6;

[0075] When the load base 8 moves downward, it will compress the pressure spring 5 through the docking block 3. When the pressure spring 5 is compressed, the pressure spring 5 moves downward relative to the sensor 6. At this time, the sensor extends above the docking block 3 with the cooperation of the clearance hole 11, so that the load base 8 can contact it. When there are some errors in the docking of the load base 8, the pressure spring 5 can provide some compensation. When the load base 8 docks, there will be a certain impact force between the load base 8 and the docking device. The pressure spring 5 can reduce the impact force of the equipment.

[0076] The height of sensor 6 is matched with the height of load support block 7;

[0077] When the load base 8 moves downward, it will compress the pressure spring 5 through the docking block 3. When the pressure spring 5 is compressed, the pressure spring 5 moves downward relative to the sensor 6. At this time, the sensor extends above the docking block 3 with the cooperation of the clearance hole 11, so that the load base 8 can contact it.

[0078] When the lower end face of the load base 8 contacts the sensor 6, the sensor 6 sends a signal. At this time, the electric locking device 2 receives the signal and pushes out the locking pin 4. One end of the locking pin 4 passes through the through hole 10 and is inserted into the interior of the load base 8, so that the load base 8 is completely fixed and prevents the load base 8 from moving.

[0079] Furthermore, when the lower end face of the load base 8 contacts the sensor 6, the lower end face of the load base 8 also contacts the load support block 7. The load support block 7 effectively supports the weight of the load base 8 and is the main load-bearing point in the transfer device.

[0080] Example 1

[0081] like Figures 1-5 As shown, a locking mechanism for a railway locomotive trench flaw detection equipment transfer device includes:

[0082] The docking base 1 is installed on the transfer device, and a load base 8 is snapped onto the docking base 1. The load base 8 is connected to the bottom of the railway locomotive trench flaw detection equipment.

[0083] The load base 8 is fixedly connected to the bottom of the flaw detection equipment. When the flaw detection equipment needs to be placed on the transfer device, the load base 8 is snapped onto the docking base 1, thereby fixing the flaw detection equipment to the transfer device, and then the equipment is transferred.

[0084] Example 2

[0085] like Figures 1-5 As shown, a locking mechanism for a railway locomotive trench flaw detection equipment transfer device includes:

[0086] A docking base 1 is installed on a transfer device, and a load base 8 is snapped onto the docking base 1. The load base 8 is connected to the bottom of the railway locomotive trench flaw detection equipment.

[0087] An electric locking device 2 is provided at the position of the docking base 1 corresponding to the load base 8, and a locking pin 4 is provided on the electric locking device 2. The load base 8 is provided with a fixing hole at the position of the locking pin 4 for locking the load base 8.

[0088] Sensor 6 is mounted on docking base 1 and is electrically connected to electric locking device 2.

[0089] The load base 8 is fixedly connected to the bottom of the flaw detection equipment. When the flaw detection equipment needs to be placed on the transfer device, the load base 8 is snapped onto the docking base 1. Then, the load base 8 is sensed by the sensor 6. After the load base 8 is sensed, the electric locking device 2 is activated, pushing out the locking pin 4. The end of the locking pin 4 is inserted into the inside of the fixing hole to complete the fixation of the load base 8, thereby fixing the flaw detection equipment to the transfer device.

[0090] Example 3

[0091] like Figures 1-5 As shown, there are two sets of docking bases 1. The two sets of docking bases 1 can clamp the load base 8. When the load base 8 is engaged between the two sets of docking bases 1, the docking base 1 has a certain range of correction for the lateral offset of the load base 8, so that the load can be more accurately and conveniently combined with the docking structure.

[0092] Both sets of docking bases 1 have beveled surfaces 12 on the upper end of the side wall of the side that are close to each other.

[0093] The beveled surface 12 maximizes the opening size at the upper end of the two sets of docking bases 1, making it easier for the load base 8 to be inserted into the middle position of the two sets of docking bases 1, and allowing the load base 8 to be more accurately and conveniently combined with the docking structure.

[0094] Example 4

[0095] like Figures 1-5 As shown, both sets of docking bases 1 are provided with matching load support blocks 7 on the same side wall, and both sets of load support blocks 7 are provided with threaded holes 9.

[0096] The two sets of docking bases 1 have matching threaded holes at the positions of the threaded holes 9 on the corresponding load support blocks 7 on their side walls. The fixing bolts pass through the threaded holes 9 and are screwed into the threaded holes on the docking bases 1. The load support blocks 7 are fixed to the two side walls of the docking bases 1 by the fixing bolts.

[0097] When the load base 8 is inserted into the middle position of the two sets of docking bases 1, the load base 8 has a large weight, so the pressure spring 5 and locking pin 4 alone cannot support the load base 8 for a long time. However, this structure can effectively support the weight of the load base 8, so this structure is the main load-bearing point in the transfer device.

[0098] Example 5

[0099] like Figures 1-5 As shown, sensor 6 is fixedly installed at the center of the two docking bases 1.

[0100] Two sets of docking bases 1 are provided with through holes 10 at the positions of the corresponding electric locking devices 2.

[0101] A matching locking pin 4 is fixedly installed at the corresponding through hole 10 position of the output end of the electric locking device 2;

[0102] The end of the locking pin 4 away from the electric locking device 2 is inserted into the interior of the through hole 10, and the size of the locking pin 4 matches the internal size of the through hole 10.

[0103] When the load base 8 is inserted into the middle position of the two sets of docking bases 1, the docking groove 13 opened on the lower end face of the load base 8 will be snapped onto the docking block 3.

[0104] When the lower end face of the load base 8 comes into contact with the sensor 6, the sensor 6 sends a signal. At this time, the electric locking device 2 receives the signal and pushes out the locking pin 4. One end of the locking pin 4 passes through the through hole 10 and is inserted into the interior of the load base 8, so that the load base 8 is completely fixed and prevents the load base 8 from moving.

[0105] Example 6

[0106] like Figures 1-5 As shown, a matching pressure spring 5 is fixedly installed at the center position of the two sets of docking bases 1 corresponding to the position of the sensor 6.

[0107] The pressure spring 5 is sleeved on the outside of the sensor 6, and a matching mating block 3 is fixedly installed on the upper end face of the pressure spring 5.

[0108] When the load base 8 moves downward, it will compress the pressure spring 5 through the docking block 3. When there are some errors in the docking of the load base 8, the pressure spring 5 can provide some compensation. In addition, when the load base 8 docks, there will be a certain impact force between the load base 8 and the docking device. The pressure spring 5 can reduce the impact force of the equipment.

[0109] Example 7

[0110] like Figures 1-5 As shown, a docking groove 13 is provided at the position of the corresponding docking block 3 of the load base 8.

[0111] When the load base 8 is inserted into the middle position of the two sets of docking bases 1, the docking groove 13 opened on the lower end face of the load base 8 will be engaged with the docking block 3. Through the cooperation of the docking block 3, the vertical sliding and displacement of the equipment is prevented.

[0112] A clearance hole 11 is provided at the position of the corresponding sensor 6 in the docking block 3, and the size of the clearance hole 11 matches the size of the sensor 6.

[0113] When the load base 8 moves downward, it will compress the pressure spring 5 through the docking block 3. When the pressure spring 5 is compressed, the pressure spring 5 moves downward relative to the sensor 6. At this time, the sensor extends above the docking block 3 with the cooperation of the clearance hole 11, so that the load base 8 can contact it. When there are some errors in the docking of the load base 8, the pressure spring 5 can provide some compensation. When the load base 8 docks, there will be a certain impact force between the load base 8 and the docking device. The pressure spring 5 can reduce the impact force of the equipment.

[0114] Example 8

[0115] like Figures 1-5 As shown, the height of sensor 6 matches the height of load support block 7.

[0116] When the load base 8 moves downward, it will compress the pressure spring 5 through the docking block 3. When the pressure spring 5 is compressed, the pressure spring 5 moves downward relative to the sensor 6. At this time, the sensor extends above the docking block 3 with the cooperation of the clearance hole 11, so that the load base 8 can contact it.

[0117] When the lower end face of the load base 8 comes into contact with the sensor 6, the sensor 6 sends a signal. At this time, the electric locking device 2 receives the signal and pushes out the locking pin 4. One end of the locking pin 4 passes through the through hole 10 and is inserted into the interior of the load base 8, so that the load base 8 is completely fixed and prevents the load base 8 from moving.

[0118] Furthermore, when the lower end face of the load base 8 contacts the sensor 6, the lower end face of the load base 8 also contacts the load support block 7. The load support block 7 effectively supports the weight of the load base 8 and is the main load-bearing point in the transfer device.

[0119] When the flaw detection equipment needs to be moved to the trench to perform flaw detection work on the wheelsets of other locomotives, the flaw detection equipment is parked on the track. The transfer device runs to the bottom of the flaw detection equipment, and the flaw detection equipment lands on the bearing surface of the transfer device. When the sensor 6 on the transfer device senses the load base 8, it is aligned. Then the electric locking device 2 receives the signal and pushes out the locking pin 4. One end of the locking pin 4 passes through the through hole 10 and is inserted into the interior of the load base 8, so that the load base 8 is completely fixed and prevented from moving. Then the flaw detection equipment is transferred to the target trench position. The locking structure of the transfer device releases the flaw detection equipment, and the flaw detection equipment begins flaw detection in the trench.

[0120] This mechanism is suitable for large-scale fixed moving equipment with heavy loads. It can effectively reduce the impact and displacement forces on metal. The size of the structure can be changed according to the applicable scenario, and appropriate materials can be selected according to the environment. This structure is currently made of steel.

[0121] This docking device is used for the transfer and fixing of railway flaw detection equipment. The two fixing methods can be used separately or in combination. It can be improved according to factors such as the size of the transfer equipment and has a wide range of applications.

[0122] Although the invention has been described with reference to preferred embodiments, various modifications can be made and components can be replaced with equivalents without departing from the scope of the invention. In particular, the technical features mentioned in the various embodiments can be combined in any manner as long as there is no structural conflict. The invention is not limited to the specific embodiments disclosed herein, but includes all technical solutions falling within the scope of the claims.
