Description
Technical Field
The utility model relates to the technical field of railway equipment, in particular to a cab apron device.
Background
With the rapid development of the economy and the optimization and adjustment of the social industry structure in China, the railway piggyback transportation can meet the rapid and flexible cargo transportation demands. Piggyback transportation takes a highway truck, a semitrailer and a container as main transportation objects, and creates a new situation of multi-type intermodal piggyback transportation in China.
The conventional humpback transportation mode is that after a train arrives at a loading and unloading yard, the train is stopped within a specified position range by utilizing facilities such as iron shoes, and the ground equipment of the matched loading and unloading yard lifts a concave underframe in the middle of the train to a certain height, winds a middle rotating shaft and rotates a certain angle, so that the train is in a loading state. Because of the requirements of railway vehicle limit, the height difference between the bottom surface of the rail and the ground and the structural characteristics of the train, when the concave underframe in the middle of the train rotates to a loading state, the height difference between the bottom surface of the concave underframe and the platform of the bottom surface of the rail is approximately 1 meter.
Therefore, in the existing railway freight transportation site, how to overcome the height difference between the train and the platform and provide a reliable device for safe loading and unloading of the train, and ensuring that the loading and unloading of the train is linked smoothly becomes an important problem.
Disclosure of Invention
The utility model aims to provide a novel technical scheme of a cab apron device, and the structure of the cab apron device is improved to ensure that the loading and unloading connection of a train is smooth.
In an embodiment of the present utility model, there is provided a cab apron device for assisting in loading and unloading a piggyback carrier, the cab apron device connecting a floor and a rotated concave chassis in a height direction, characterized in that the cab apron device includes: the first plate group comprises a first transition plate, and one end of the first transition plate is connected with the ground; the second plate group comprises a second transition plate, the other end of the first transition plate is connected with the second transition plate, the first transition plate and the second transition plate are obliquely arranged on the ground, and the inclination angle of the first transition plate is larger than that of the second transition plate; and the support base is used for supporting the first plate group and the second plate group.
When loading and unloading humpback transportation, the cab apron device makes up the fall between the platform ground and the concave underframe, and the vehicle to be loaded and unloaded runs onto the rotated concave underframe through the cab apron device or runs out from the concave underframe to the platform ground through the cab apron device. When the vehicle to be loaded and unloaded enters the cab apron device from the ground, the vehicle to be loaded and unloaded is firstly contacted with the first transitional plate, and the gravity center of the vehicle to be loaded and unloaded is lower. Even if the inclination angle of the first transition plate is larger than that of the second transition plate, the gradient of the first transition plate is larger, so that climbing stability of the vehicle to be assembled and disassembled can be ensured; meanwhile, the gradient of the first transition plate is larger, so that the length of the first transition plate can be reduced, and the dimension of the transition plate device in the length direction can be saved.
When the vehicle to be loaded and unloaded climbs to the second transition plate, the center of gravity of the vehicle to be loaded and unloaded is further raised. The second transition plate has a smaller inclination angle and a slower gradient, and the vehicle to be loaded and unloaded can stably climb to the concave underframe.

Detailed Description
In order to better understand the aspects of the present utility model, the present utility model will be described in further detail with reference to the accompanying drawings and detailed description.
According to one embodiment of the present application, a cab apron device for a ground equipment-driven loading and unloading piggyback carrier in this embodiment is described with reference to fig. 1 to 9, and includes a first plate group, a second plate group, and a support base 11 for supporting the first plate group and the second plate group, where the first plate group and the second plate group are arranged along a direction in which a vehicle to be loaded and unloaded is driven into a concave chassis, i.e., the vehicle to be loaded and unloaded can pass through the first plate group and the second plate group in order and then reach the concave chassis (not shown in the figure) of a train. The first plate package comprises a first transition plate 1 and the second plate package comprises a second transition plate 4.
Specifically, as shown in fig. 1, the cab apron device is fixed to the ground and located at both ends of the concave underframe after the train rotates. The cab apron device is connected with the ground and the rotated concave bottom frame in the height direction. The supporting base 11 is a frame structure welded by sectional materials and comprises a plurality of supporting longitudinal beams which are arranged in parallel, and the first transition plate 1 and the second transition plate 4 are fixedly arranged at the top ends of the plurality of supporting longitudinal beams. The first transition plate 1 and the second transition plate 4 are steel materials. One end of the first transition plate 1 is connected with the ground, the other end is connected with the second transition plate 4, and the first transition plate 1 and the second transition plate 4 are obliquely arranged on the ground and form a slope. Wherein the second transition plate 4 is closer to the concave chassis.
When loading and unloading humpback transportation, the cab apron device makes up the fall between the platform ground and the concave underframe, and the vehicle to be loaded and unloaded runs onto the rotated concave underframe through the cab apron device or runs out from the concave underframe to the platform ground through the cab apron device. When the vehicle to be loaded and unloaded enters the cab apron device from the ground, the vehicle to be loaded and unloaded is firstly contacted with the first cab apron 1, and the center of gravity of the vehicle to be loaded and unloaded is lower. Even if the inclination angle of the first transition plate 1 is larger than that of the second transition plate 4, the gradient of the first transition plate 1 is larger, and the climbing stability of the vehicle to be assembled and disassembled can be ensured; meanwhile, the larger gradient of the first transition plate 1 can reduce the length of the first transition plate 1, and thus, the dimension of the transition plate device in the length direction can be reduced.
When the vehicle to be loaded and unloaded climbs up to the second transition plate 4, the center of gravity of the vehicle to be loaded and unloaded is further raised. The second transition plate 4 has a smaller inclination angle and a slower gradient, and thus, the vehicle to be loaded and unloaded can stably climb to the concave underframe.
Therefore, the cab apron device provided by the embodiment of the utility model can make up the height difference between the platform and the concave bottom frame. In addition, the inclination angle of the first transition plate 1 is larger than that of the second transition plate 4, so that the gradient of the first transition plate 1 is larger than that of the second transition plate 4, stable climbing of a vehicle can be ensured, and the size of the transition plate device in the length direction can be reduced.
In a particular embodiment, the support base 11 is provided with a connection for detachable connection with the platform floor. Thereby enabling easy replacement and repair of the support base 11.
Specifically, referring to fig. 1, 3 and 5, the ground connection seats 7 are provided at both sides of the support base 11 in the width direction, the connection members are the ground connection seats 7, and the ground connection seats 7 can be connected with the ground by screw.
Further, referring to fig. 1, a ground connection seat 7 is also provided at least one side of the support base 11 in the length direction, and the ground connection seat 7 can be screw-connected with the ground. The ground anchor connecting seat 7 is formed by welding a high-strength steel plate and a supporting base 11 and then is connected with a ground fixing part. Therefore, the supporting base 11 can be limited in the running direction of the vehicle to be assembled and disassembled, so that the connection strength between the supporting base 11 and the ground is increased, and the supporting base 11 is prevented from moving in the length direction.
In a specific embodiment, the guide beams 2 are provided on opposite sides in the width direction of the first transition plate 1, and the two guide beams 2 extend in the length direction of the first transition plate 1. And/or the two opposite sides of the second transition plate 4 in the width direction are provided with guide beams 2, and the two guide beams 2 extend along the length direction of the second transition plate 4.
When the vehicle runs on the cab apron device, the guide beam 2 positioned outside the tire limits the tire, so that the vehicle to be loaded and unloaded can be prevented from shifting and falling from the cab apron device in the running process of the vehicle on the cab apron device.
It will be appreciated that, as shown in fig. 1, 4 and 7, the guide beam 2 may be provided only on the first transition plate 1, or the guide beam 2 may be provided on both the first transition plate 1 and the second transition plate 4, so as to further guide the belt loading and unloading vehicle.
In one example, the end of the guide beam 2 that is disposed at the first transition plate 1 that is remote from the second transition plate 4 is provided with a rounded sealing plate to form a guide slope 12. As shown in fig. 7, the guiding inclined surface 12 is opened toward the side of the first transition plate 1 away from the second transition plate 4, and when the vehicle to be loaded or unloaded is driven into the first transition plate 1, the tire of the vehicle is gradually and limitedly fitted between the two guiding beams 2 under the action of the guiding inclined surface 12. Meanwhile, the guide inclined surface 12 is formed by a round corner sealing plate, so that the damage to the tyre to be assembled and disassembled is prevented.
Optionally, referring to fig. 7, a reinforcing plate 21 is fixedly provided in the guide beam 2 to increase the structural strength of the guide beam 2, thereby preventing the wheel from being pressed over the guide beam 2 to damage the guide beam 2.
Alternatively, referring to fig. 1, the outer portions of both sides in the width direction of the first transition plate 1 and the second transition plate 4 are provided with fences 3. I.e. on the outside of the guide beam 2 a rail 3 is provided. Because the vehicle to be loaded and unloaded belongs to semi-suspension operation on the cab apron device, the fence 3 can protect the vehicle in the width direction so as to prevent the vehicle from being overturned accidentally.
In an alternative embodiment, referring to fig. 1, the first transition plate 1 and the second transition plate 4 are provided with anti-slip ribs 9 along the width direction, and the anti-slip ribs 9 comprise convex surfaces which form an arc structure. The anti-slip rib 9 extends in the width direction and is located between the two guide beams 2. The anti-slip ribs 9 are provided at intervals in the longitudinal direction. The anti-slip bead 9 may be a round steel structure fixed on the surface of the first transition plate 1 and the second transition plate 4, which are in contact with the tire to be unloaded. Therefore, the skid of the vehicle to be assembled and disassembled can be prevented, and the damage to the tire is avoided.
In some embodiments of the present utility model, referring to fig. 8 and 9, a gap protection plate 5 is pivotally connected to an end of the second transition plate 4 remote from the first transition plate 1 to cover a gap between the second transition plate 4 and the concave chassis, which has sufficient supporting strength to ensure that the vehicle runs smoothly. The gap protection plate 5 is also provided with an anti-slip rib 9 to play a role in slip prevention. How to make the gap shield plate 5 have sufficient supporting strength is a common technical means for those skilled in the art, and will not be described herein.
Specifically, two rotating shaft seats 10 are fixed on the second transition plate 4, rotating shafts 8 are in limit fit in the rotating shaft seats 10, and the gap protection plates 5 are installed on the rotating shafts 8. The gap protection plate 5 thus provided can be unfolded when needed, and rotated and stored toward the bottom of the second transition plate 4 when not needed, thereby preventing interference with the concave chassis when rotating the concave chassis.
