Description

Technical Field

[0001] The utility model relates to the technical field of railway freight transportation, in particular to a wheel blocking device for railway crawler freight transportation in which vehicles and freight are coordinated. Background Art

[0002] When transporting crawler cargo by rail, it is necessary to stably fix the crawler cargo on the railway vehicle to prevent the crawler cargo from shifting when the railway vehicle is coupled or braked, thereby causing damage to the cargo or even personal danger. At present, the railway transportation of crawler cargo generally adopts methods such as pulling ropes, tire stops, special floors, and rivet reinforcement.

[0003] The strength of the pull rope is limited, and the force on each pull rope cannot be too large. Multiple pull ropes are needed to fix the goods. When the force is uneven, the pull rope is easy to break and damage the goods. Moreover, there are many types of pull ropes, and it is not easy to choose a suitable pull rope. It is also difficult to reinforce, the operation time is long, and the manpower and material costs invested are too high.

[0004] Tire chocks are more suitable for automobile transportation. They have a small contact area with the cargo and are mostly suitable for elastic rubber tires. If used for steel tracked freight transportation, the tire chocks and tracks will be damaged.

[0005] Special floor is generally made of plain carbon steel, with convex and concave grooves, and is more used in the transportation of rubber tire cargo, which can prevent the cargo from moving when transporting tire cargo. If it is used to transport crawler cargo, the steel crawler will collide and squeeze with this special vehicle floor, damaging the crawler and the vehicle floor, so this special vehicle floor is not suitable for transporting crawler cargo; special floor has high production cost, difficult installation, and consumes a lot of human resources.

[0006] When loading crawler cargo, rivets are placed between the crawler and the wooden floor of the railway vehicle. After loading, the crawler presses the rivets into the wooden floor to fix the cargo. This reinforcement is extremely harmful to the floor of the railway vehicle, the maintenance cost is too high, and the rivets are not easy to pull out from the wooden floor after unloading.

[0007] The above reinforcement solutions are relatively backward in technology, and most of them are more suitable for tire-type cargo, but not for track-type cargo. Even if the traction ropes and rivets can meet the needs of railway transportation of track-type cargo, it will cost a lot, waste a lot of manpower and material resources, and the operation is relatively complicated, which is not conducive to railway transportation of track-type cargo.

DETAILED DESCRIPTION

[0052] The following is a description of the preferred embodiments of the present invention in conjunction with the accompanying drawings. It should be understood that the following embodiments are provided only for the purpose of illustration and are not intended to limit the scope of the present invention. Those skilled in the art may make various modifications and substitutions to the present invention without departing from the purpose and spirit of the present invention.

[0053] A wheel chock device for railway tracked cargo transport with vehicle-cargo coordination first obtains the length, width and inclination angle of the lower surface of the track according to the specifications of the tracked cargo, and then determines the specific positions of four devices placed on the outer sides of both ends of the track contact surface and the appropriate angle of the wheel chock slope according to the length, width and the lower surface of the track and the size of the railway vehicle.

[0054] The utility model device comprises an oblique block structure, a top block component, a push rod component and a combined fixing pin unit.

[0055] The oblique baffle structure comprises a baffle body 1 , two rib plates 2 and a bottom plate 3 .

[0056] The block body 1 is made of steel plate, and a rounded corner structure is set on the top to avoid stress concentration. In order to make the wheel block device fit well with different types of crawlers, the inclined block structure is designed with inclined surfaces of different angles, which are 30° and 40° respectively. In order to reduce the width of the inclined block structure, a cutoff is set at a certain height at the bottom of the inclined surface. In order to keep the width of both sides consistent, the height setting is also different. The cutoff height of one end of the 30° inclined surface is about 85mm, and the cutoff height of one end of the 40° inclined surface is about 60mm.

[0057] When in use, the block body 1 is in direct contact with the track. The rib plate 2 is composed of a whole piece of steel plate, welded inside the block body 1, and has the same inclination angle as the block body 1 on the side. Three circular weight-reducing holes are set in the middle, of which the circular hole at the top in the middle has a larger diameter, and the circular holes at the bottom on both sides have a smaller diameter. The bottom plate 3 is composed of a whole piece of steel plate. Two circular weight-reducing holes and a rectangular long hole are set on the outer sides of the two rib plates 2 on the bottom plate 3. The circular weight-reducing holes have equal diameters and are located at both ends of the horizontal direction. The rectangular long hole is located in the middle, which is used to insert the oblique block combination fixing pin 13 to fix the wheel block device.

[0058] The top block comprises a top piece 4, a push rod sleeve 5 and a locking bolt 6. The push rod comprises a fixing plate 7 and a push rod 8.

[0059] The top piece is tightly attached to the end of the oblique block structure, and can transmit the longitudinal force of the oblique block structure. The push rod sleeve 5 is a hollow cylinder, one side of which is welded to the end of the top piece 4, and the other side is attached to the front end of the push rod 8. A round hole is opened on the top for inserting the anti-loosening bolt 6. The anti-loosening bolt 6 is located at the top of the push rod sleeve 5, attached to the push rod 8, and is used to fix the push rod 8 and the push rod sleeve 5 to limit the relative displacement between the two.

[0060] A circular hole is opened on the top of the fixing plate 7, and the diameter of the circular hole matches the diameter of the push rod 8. The push rod 8 can be inserted into the circular hole. Two rounded rectangular holes are opened on the floor of the fixing plate 7. The fixing plate assembly fixing pin 9 is used to fix the push rod assembly to the vehicle floor to prevent the fixing plate 7 from jumping up. Two bumps are provided at the bottom of the fixing plate 7 for connecting and fixing the fixing plate 7 to the vehicle floor. The push rod 8 is a steel cylinder, connecting the push rod sleeve 5 and the fixing plate 7. One end of the fixing plate 7 is provided with a hexagonal rod head, which can correspond to the nut.

[0061] The combined fixing pin unit includes two groups of oblique block combined fixing pins 13 and two groups of fixed plate combined fixing pins 9. The oblique block combined fixing pins 13 are similar in structure to the fixed plate combined fixing pins 9, and differ only in size.

[0062] The fixed plate assembly fixing pin 9 comprises a center pin 10, a spring 11 and a fixing pin 12. The oblique block assembly fixing pin 13 is also like this.

[0063] The fixing pin 12 is located in the middle of the fixing pin 9 of the fixing plate assembly, and is used to be inserted into the wheel chock device and the vehicle floor, and bears the main longitudinal force. The cylindrical size of the fixing pin 12 matches the size of the hole, and the pin top size of the fixing pin 12 is slightly larger than the cylindrical size of the fixing pin 12, which can prevent the fixing pin 12 from falling out of the hole. The maximum vertical dimension of the fixing pin 12 is the hole depth of the wheel chock device. The middle pin 10 is an I-shaped as a whole, with a handle at the upper end for easy operation, and the spring 11 is located between the middle pin 10 and the pin top of the fixing pin 12. When in use, the middle pin 10 is embedded in the bottom groove of the fixing pin 12 to prevent the vertical jump and circumferential rotation of the fixing pin 9 of the fixing plate assembly from occurring during movement.

[0064] When in use, the rectangular holes on both sides of the bottom plate 3 are aligned with the openings of the vehicle floor respectively. If there is a non-single alignment method, the alignment method in which the longitudinal center line of the oblique block structure is close to the longitudinal center line of the track and the longitudinal center line of the vehicle is selected.

[0065] Place a push rod assembly at the rear end of the oblique block structure: fit the top block 4 of the top block assembly to the rear end of the block body 1, and at a suitable position behind the top block 4, insert the fixed plate 7 protrusion of the push rod assembly into the hole of the vehicle floor, and fix the push rod 8 of the push rod assembly on the fixed plate 7. The anti-loosening bolt 6 is not tightened, and the push rod 8 can move forward and backward by rotation. Use a tool to rotate the rear end of the push rod 8 of the push rod assembly, so that the push rod 8 enters the push rod sleeve 5 and fits with the top piece 4, and pushes the fixed plate assembly fixing pin 9 and the oblique block assembly fixing pin 13. Fix the fixed plate 7 and the fixed plate assembly fixing pin 9, as well as the fixed plate 7 and the oblique block assembly fixing pin 13 in the groove of the push rod assembly and the corresponding position of the rectangular hole at the bottom of the oblique block. First, put the middle pin 10 through the hole, then rotate 90 degrees, and embed it into the bottom groove of the combination fixing pin 9 on the fixed plate 7.

[0066] Finally load two wheel chocks of crawler cargo rear end, and specific method is the same. At this moment, crawler cargo is firmly fixed on the railway vehicle by four wheel chocks.

[0067] Working principle: first calculate the blocking angle suitable for tracked cargo to select a suitable wheel blocking surface; press the top piece 4 against the end of the blocking body 1, adjust the position of the fixing plate 7 and the position of the push rod 8 in the push rod sleeve 5, and change the loading position of the device as a whole; after positioning is completed, tighten the anti-loosening bolt 6 to prevent the wheel blocking device from moving longitudinally, and screw in the fixing plate combination fixing pin 9 and the oblique block combination fixing pin 13 to complete the overall fixation.

[0068] The contents not described in detail in this specification belong to the prior art known to professional and technical personnel in this field.

[0069] Finally, it should be noted that the above description is only a preferred example of the utility model and is not intended to limit the utility model.
