Description

Technical Field

[0001] The invention relates to the technical field of railway locomotive trench wheel pair flaw detection equipment, in particular to a locking mechanism of a railway locomotive trench flaw detection equipment transfer device. Background Art

[0002] Wheel flaw detection is a crucial link in the routine maintenance and overhaul of locomotives. This process is usually carried out in a special overhaul trench to ensure the accuracy and comprehensiveness of the detection. However, when a flaw detection operation is completed, if the flaw detection equipment needs to be moved to another overhaul trench to continue other operations, this involves a key issue: how to move these precise and relatively bulky equipment safely and efficiently.

[0003] In order to solve this problem, a special transfer device is usually used. This transfer device is cleverly designed to accommodate flaw detection equipment of different sizes and weights to ensure 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. During the transfer process, if the equipment is not properly fixed and locked on the transfer device, it is very likely to be displaced or slipped due to vibration, bumps or human error.

[0004] Once the equipment is displaced 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, which will not only affect the subsequent NDT results, but may also lead to high maintenance costs and longer downtime. More seriously, if the equipment slides and hits the workers in the trench, it may cause casualties, causing irreparable losses and legal liabilities to the company. Summary of the invention

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

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

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

[0008] An electric locker is arranged at a position of the docking base corresponding to the load base, and a locking pin is arranged on the electric locker, and a fixing hole is opened at a position of the load base corresponding to the locking pin;

[0009] A sensor is arranged on the docking base, and the sensor is electrically connected to the electric locker;

[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 of 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 locker is started, and the locking pin is pushed out and inserted into the load base, thereby fixing the flaw detection equipment to the transfer device, and then the transfer equipment is carried out.

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

[0012] The upper end surfaces of the side walls of the two groups of docking bases that are close to each other are both provided with chamfered surfaces;

[0013] The setting of the beveled surface increases the opening size of the upper ends of the two sets of docking bases as much as possible, 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 fixture.

[0014] The side walls on the same side of the two groups of docking bases are both provided with matching load support blocks, and threaded holes are opened on the two groups of load support blocks.

[0015] Matching threaded holes are provided on the side walls of the two groups of docking bases at positions corresponding to the threaded holes on the load support blocks. 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 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 the fixing pin alone cannot support the load for a long time, but this structure can effectively support the weight of the load base, so this structure is the main load-bearing point in the transfer device.

[0017] The sensor is fixedly arranged at the center position of the two groups of docking bases.

[0018] Through holes are provided at positions of the two groups of docking bases corresponding to the electric lockers.

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

[0020] One end of the locking pin away from the electric locker is inserted into the interior of the through hole, and the size of the locking pin matches the internal size of the through hole.

[0021] When the load base is inserted into the middle position of the two groups of docking bases, the docking groove arranged on the lower end surface of the load base will be connected to the docking block.

[0022] When the lower end surface of the load base contacts the sensor, the sensor sends a signal. At this time, the electric locker 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 to prevent the load base from moving.

[0023] Matching pressure springs are fixedly arranged at the central positions of the two groups of docking bases corresponding to the positions of the sensors.

[0024] The pressure spring is sleeved on the outside of the sensor, and a matching docking block is fixedly arranged on the upper end surface of the pressure spring.

[0025] When the load base moves downward, the pressure spring will be compressed through the docking block. When some errors occur in the docking of the load base, the pressure spring can provide certain compensation. When the load base is docked, there will be a certain impact force between the load base and the docking device. The pressure spring can reduce the impact force of the equipment.

[0026] A docking groove is provided at a position of the load base 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 provided on the lower end surface of the load base will be snapped onto the docking block, and the cooperation of the docking block prevents the device from sliding and deflecting in the vertical direction.

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

[0029] When the load base moves downward, the pressure spring will be compressed 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 give way hole, extends to the top of the docking block so that the load base can contact it. When some errors occur in the docking of the load base, the pressure spring can give certain compensation. When the load base is docked, there will be a certain impact force between the load base and the docking device. The pressure spring can reduce the impact force of the equipment.

[0030] The height of the sensor matches the height of the load supporting block.

[0031] When the load base moves downward, the pressure spring will be compressed 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 surface of the load base contacts the sensor, the sensor sends a signal. At this time, the electric locker 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 to prevent the load base from moving.

[0033] When the lower end surface of the load base contacts the sensor, the lower end surface of the load base also contacts the load support block, and the weight of the load base is effectively supported by the load support block, which is the main load-bearing point in the transfer device.

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

[0035] The load base can be directly plugged between two sets of docking bases to fix the railway locomotive trench flaw detection equipment and limit 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, and then the load base is fixed by using a sensor plus an electric locking pin.

[0037] When the flaw detection equipment is ready for transportation, the positioning device on the equipment is used to align the equipment with the locking mechanism, and then the locking mechanism on the transfer device starts to dock with the bottom of the flaw detection equipment. There is a corresponding notch at the bottom of the flaw detection equipment. When the flaw detection equipment is docked, the docking block in the locking structure is first connected with the bottom card slot, and then the spring inside the docking device will be compressed. At this time, the impact force of the equipment will be weakened. When the spring is compressed to a certain extent, the sensor will sense that the equipment has been 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 transfer device is completed, and the flaw detection equipment begins to be transported;

[0038] The docking and fixing device adopts a combination of mechanical adaptive technology and electric control sensing technology to achieve fixed locking. It uses the performance of mechanical locking structure and spring, and combines sensors and electric control technologies to achieve higher stability and reliability.

[0056] The load base 8 is fixedly connected to the bottom of the flaw detection device. When the flaw detection device needs to be placed on the transfer device, the load base 8 is clamped on the docking base 1 to fix the flaw detection device to the transfer device, and then the transfer device is carried out.

[0057] The setting of two sets of docking bases 1 can clamp the load base 8.

[0058] The upper end surfaces of the side walls of the two sets of docking bases 1 that are close to each other are both provided with chamfered surfaces 12;

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

The fixing bolts pass through the threaded holes 9 and are screwed into the threaded holes provided on the docking base 1. The load support blocks 7 are fixed to the side walls of the docking base 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, since the load base 8 has a large weight, the pressure spring 5 and the locking pin 4 alone cannot support the load base 8 for a long time, but 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.

[0067] When the load base 8 is inserted into the middle position of the two sets of docking bases 1, the docking groove 13 provided on the lower end surface of the load base 8 will be connected to the docking block 3;

[0068] When the lower end surface of the load base 8 contacts the sensor 6, the sensor 6 sends a signal. At this time, the electric locker 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 to prevent the load base 8 from moving.

[0071] When the load base 8 moves downward, the pressure spring 5 will be compressed through the docking block 3. When some errors occur in the docking of the load base 8, the pressure spring 5 can provide certain compensation. When the load base 8 is docked, 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 load base 8 corresponding to the docking block 3;

[0075] When the load base 8 moves downward, the pressure spring 5 will be compressed through the docking block 3. When the pressure spring 5 is compressed, the pressure spring 5 moves downward relative to the sensor 6.

[0090] Embodiment 3

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

[0092] The upper end surfaces of the side walls of the two sets of docking bases 1 that are close to each other are both provided with chamfered surfaces 12 .

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

[0097] When the load base 8 is inserted into the middle position of the two sets of docking bases 1, since the load base 8 has a large weight, the pressure spring 5 and the locking pin 4 alone cannot support the load base 8 for a long time, but 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.

[0103] When the load base 8 is inserted into the middle position of the two sets of docking bases 1 , the docking groove 13 provided on the lower end surface of the load base 8 will be snap-connected to the docking block 3 .

[0104] When the lower end surface of the load base 8 contacts the sensor 6, the sensor 6 sends a signal. At this time, the electric locker 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 to prevent the load base 8 from moving.

[0105] Embodiment 6

[0106] like Figure 1-Figure 5 As shown, matching pressure springs 5 ​​are fixedly arranged at the positions of the sensors 6 at the center positions of the two groups of docking bases 1 .

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

[0108] When the load base 8 moves downward, the pressure spring 5 will be compressed through the docking block 3. When some errors occur in the docking of the load base 8, the pressure spring 5 can provide certain compensation. When the load base 8 is docked, 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] Embodiment 7

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

[0111] When the load base 8 is inserted into the middle position of the two docking bases 1, the docking groove 13 provided on the lower end surface of the load base 8 will be snapped onto the docking block 3, and the docking block 3 cooperates to prevent the device from sliding and deflecting in the vertical direction.

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

[0113] When the load base 8 moves downward, the pressure spring 5 will be compressed 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, with the cooperation of the clearance hole 11, extends to the top of the docking block 3, so that the load base 8 can contact it, and when some errors occur in the docking of the load base 8, the pressure spring 5 can give certain compensation, and when the load base 8 is docked, the load base 8 and the docking device will have a certain impact force, and the pressure spring 5 can reduce the impact force of the equipment.

[0114] Embodiment 8

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

[0116] When the load base 8 moves downward, the pressure spring 5 will be compressed 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, with the cooperation of the clearance hole 11, extends to the top of the docking block 3, so that the load base 8 can contact it.

[0117] When the lower end surface of the load base 8 contacts the sensor 6, the sensor 6 sends a signal. At this time, the electric locker 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 to prevent the load base 8 from moving.

[0118] When the lower end surface of the load base 8 contacts the sensor 6, the lower end surface of the load base 8 also contacts the load support block 7. The weight of the load base 8 is effectively supported by the load support block 7, which is the main load-bearing point in the transfer device.

[0119] When the flaw detection equipment needs to be turned to the ditch to perform flaw detection operations on other locomotive wheels, 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 carrying surface of the transfer device. When the sensor 6 on the transfer device senses the load base 8, it is aligned in place, and then the electric locker 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 to prevent the load base 8 from moving. Then the flaw detection equipment is transported to the target ditch position, and the locking structure of the transfer device releases the flaw detection equipment, and the flaw detection equipment arrives at the ditch to start flaw detection.

[0120] This mechanism is suitable for large load-fixed sports equipment and can effectively reduce the impact force and offset force of metal. The size of the structure can be changed according to the applicable scenario, and the appropriate material can be selected according to the environment. This structure is currently made of steel.

[0121] The docking device is used for the transportation and fixation of railway flaw detection equipment. The two fixing methods can be disassembled and used separately or combined. It can be improved according to factors such as the size of the transportation equipment and has a wide range of application scenarios.
