Description

Technical Field

[0001] The invention belongs to the technical field of rail vehicle rescue, and in particular relates to a vehicle-mounted moving and lifting device for rail vehicle rescue. Background Art

[0002] In the existing technology of rail vehicles, the vehicle is generally equipped with a car frame and a crane position, and there is a re-railing position at the end. These structural parts are welded to the lower part of the chassis of the vehicle body, and its operating plane is parallel to the track plane. There are longitudinal and transverse stops at the points to prevent the car frame and crane equipment from sliding horizontally and longitudinally during operation. These structures are all considered to be used under normal working conditions during normal production, transportation, repair and maintenance, and can only be used based on specific car frame and crane tooling tools. For on-site rescue in special circumstances such as large derailment, lateral displacement, tilting, overturning, and body deformation of the vehicle caused by uncertain reasons such as collisions and natural disasters, including outdoor crane lifting and displacement, vehicle lateral displacement, pulling and resetting, and vehicle flipping and correction, the existing car frame and crane position will not have these functions because it only has an operating plane parallel to the track surface and requires a dedicated car frame and lifting tooling, and cannot meet the requirements of on-site rapid rescue. When this type of rescue occurs, the lifting plan is often discussed and studied on site or the entire vehicle body is wrapped and tied, etc., which is extremely low in professionalism, timeliness and safety. Summary of the invention

[0003] The present invention aims to solve the on-site rescue in special circumstances such as vehicle derailment, lateral displacement, tilting, overturning, and body deformation caused by uncertain reasons such as collision and natural disasters after an accident, including the problem of rapid rescue by outdoor crane lifting and displacement, vehicle lateral displacement and pulling reset, and vehicle flipping and straightening. The present invention provides a vehicle-mounted lifting and hoisting device for rail vehicle rescue, which can meet various operational requirements for changing the position and state of the vehicle under the above-mentioned rescue conditions. The operation is not based on specific tooling, and the needs for rapid rescue using wire ropes on site by cranes or engineering vehicles can be met. The device has the characteristics of high integration, easy use, and high safety, and can solve various requirements for vehicle position lifting and hoisting in on-site rescue, and ultimately achieve the purpose of rapid resumption of operation and shortening rescue time.

[0004] To achieve the above-mentioned purpose of the invention, the present invention provides a vehicle-mounted moving and lifting device for rail vehicle rescue, which is installed on the chassis side beams on both sides of the vehicle body, and the vehicle-mounted moving and lifting device includes an annular bearing body and a rotating pin shaft. Circular holes are processed on the side surfaces of the chassis side beams and the vertical support plates on the inner side thereof, and the annular bearing body is installed in the circular hole and fixedly connected with the side surfaces of the chassis side beams and the vertical support plates on the inner side thereof, and the internal full thread of the annular bearing body cooperates with the external thread of the rotating pin shaft; a front bearing hole for connecting a binding steel cable is provided near the outer end of the rotating pin shaft; an annular limit stop is provided on the inner side of the annular body near the outer end of the annular bearing body, and the inner diameter of the limit stop is smaller than the inner diameter of the annular bearing body, and the diameter of the stop surface at the outer end of the rotating pin shaft is larger than the inner diameter of the annular bearing body, and the inner end of the rotating pin shaft is detachably connected to the rear stop cover; when resetting, the rotating pin shaft is screwed inward, and its outer end stop surface is close to the limit stop; when opening, the rotating pin shaft is screwed outward, and the rear stop cover contacts the inner end of the annular bearing body.

[0005] Furthermore, a gap for installing an internal annular sealing strip is provided between the limit stop and the annular carrier. After the internal annular sealing strip is installed, the lower part protrudes outward in a semicircular shape, and the outermost side is flush with the outer side surface of the limit stop.

[0006] Furthermore, the outer side of the rotating pin shaft close to the front bearing hole is a smooth cylinder, and the diameter thereof is smaller than the inner diameter of the external thread.

[0007] Furthermore, the rotating pin shaft is provided with a rear bearing hole near the inner end thereof for connecting the binding steel cable during resetting, and the rear bearing hole is rotated out of the inner end of the annular bearing body during resetting.

[0008] Furthermore, the outer end surface of the rotating pin shaft is provided with concave four-corner holes for adjusting its working position, and the upper sides of the four-corner holes are provided with operation direction indicators.

[0009] The present invention can be used for on-site rescue in special circumstances such as vehicle derailment, lateral displacement, tilting, rollover, and body deformation caused by uncertain reasons such as collision and natural disasters after an accident, including various operational requirements for adjusting the position of the vehicle after lifting by an outdoor crane, lateral pulling and resetting of the vehicle, and flipping and straightening of the vehicle. The operation is not based on specific tooling, and can meet the needs of rapid rescue using a wire rope on site by a crane or an engineering vehicle. The present invention has the characteristics of high integration, convenience in use, and high safety, and can meet various requirements for vehicle position shifting and lifting in on-site rescue, ultimately achieving the purpose of rapid resumption of operation and shortening rescue time, and minimizing the impact of the accident.

[0030] In order to better understand the purpose, structure and function of the present invention, the following is a further detailed description of a vehicle-mounted lifting and moving device for rail vehicle rescue of the present invention in conjunction with the accompanying drawings.

[0031] Through completely independent research and development, a vehicle-mounted lifting device 1 for vehicle rescue is invented. The device is installed on the side beam 2 of the vehicle body chassis by welding, two on each side, and four per vehicle in total. In order to meet the double-end or single-end lifting that may occur in different rescue conditions, the device is arranged near the center of the bogie 3, see attached Figure 1 .

[0032] Under normal operating conditions during the life cycle of the vehicle, it is generally not necessary to activate the vehicle-mounted lifting device 1. In this state, the device is kept flush with the outer side 2 of the vehicle body chassis, does not affect the vehicle's operating limits, and has no effect on vehicle operation and maintenance. Figure 2 .

[0033] In order to provide sufficient strength, the vehicle-mounted lifting device 1 is installed in the chassis side beam circular hole 4 and the inner vertical support plate circular hole 5 on the outer side of the vehicle body chassis 2 by welding. The continuous weld 7 around the chassis side beam circular hole and the continuous weld 6 around the inner support plate circular hole are used for connection. The exposed part in contact with the vehicle body outer plate 8 is treated with appearance sealant 9, such as Figure 3 and Figure 4 .

[0034] The vehicle-mounted rescue lifting device 1 comprises an annular bearing body 11 and a rotating pin 12. The internal thread 111 of the annular bearing body and the external thread 127 of the rotating pin 12 are mechanically matched to transfer loads of various working conditions.

[0035] Through the concave four-corner hole 123 provided on the outer end surface of the rotating pin 12, the rotating pin 12 can be adjusted to two working positions in the annular carrier 11, namely, the opening and resetting positions of the lifting device 1. When the vehicle is in normal operation, the position mark 124 on the front of the lifting device 1 indicates the top, which is in the reset state. The outer surface of the rotating pin 12 is flush with the side of the vehicle body. The limit stop 112 of the annular carrier is in close contact with the front cover of the rotating pin under the action of the preload force, and the internal annular sealing strip 113 is compacted to achieve sealing. Figures 5 to 9 .

[0036] A front bearing hole 121 for connecting the binding steel cable 10 is provided near the outer end of the rotating pin 12. The outer side of the rotating pin 12 near the front bearing hole 121 is a smooth cylinder with a diameter smaller than the inner diameter of the external thread 127. A ring-shaped stopper 112 is provided on the inner side of the ring-shaped support body 11 near the outer end. The inner diameter of the stopper 112 is smaller than the inner diameter of the ring-shaped support body 11. A gap for installing an internal ring-shaped sealing strip is provided between the stopper 112 and the ring-shaped support body 11. After the internal ring-shaped sealing strip is installed, the lower part protrudes outward in a semicircular shape, and the outermost side is flush with the outer side of the stopper 112. The diameter of the stopper surface at the outer end of the rotating pin 12 is larger than the inner diameter of the ring-shaped support body, and the inner end of the rotating pin 12 is detachably connected to the rear stopper cover 126. A rear bearing hole 122 is provided near the inner end of the rotating pin 12.

[0037] In the reset position, the rotating pin 12 is screwed inward, and its outer end stop surface is close to the limit stop 112. When resetting, the rear bearing hole 122 is screwed out of the inner end of the annular bearing body 11, and the binding cable 10 is connected to the rear bearing hole 122 on the rotating pin 12, which can be used for binding during vehicle transportation. Fig.10 and Fig.11 .

[0038] When the lifting device 1 is turned on, the pin 12 is rotated according to the direction indication 125 of the operation, and the rotating pin 12 is rotated outward, so that the rear stop cover 126 and the annular carrier 11 contact each other, which is achieved by the precisely designed thread length and pitch of the rotating pin 12. At this time, the front bearing hole 121 of the rotating pin protrudes out of the annular carrier. Fig.12 and Fig.13 .

[0039] For the working condition that the rescue vehicle needs to be lifted by a crane, it is only necessary to open the four lifting devices 1 of the vehicle, connect the binding cable 10 to the front bearing hole 121 on the rotating pin 12, and use it as a cable or hook of a crane or engineering vehicle to lift upward without the need for special lifting equipment. The vehicle moves upward in the direction 20 shown in the figure. The application scenario is as follows Fig.14 and Fig.15 .

[0040] For the working condition that the rescue vehicle needs to move the vehicle sideways, it is only necessary to open the single-side lifting device 1, connect the binding cable 10 to the front bearing hole 121 on the rotating pin 12, and use it as a cable or hook of a crane or engineering vehicle for lateral lifting operation without the need for dedicated lifting equipment. The lateral movement direction 30 of the vehicle is shown in the figure. The application scenario is as follows Fig.16 and Fig.17 .

[0041] For rescue vehicles, it is necessary to straighten and reset the overturned vehicle on the dumping position surface 60. It is only necessary to open the upper side of the lifting device 1 and connect the binding cable 10 to the front bearing hole 121 on the rotating pin 12. The vehicle will be straightened after completing the movement of the vehicle rotating in the direction 50 under the pulling direction of the binding cable 40. It can be used as a cable or hook of a crane or engineering vehicle for lateral operation without the need for dedicated lifting equipment. Application scenarios such as Fig.18 and Fig.19 .

[0042] The entire technical route uses positive innovation in the entire process of two-dimensional design, three-dimensional design, calculation and experimental verification of relevant structural parts to meet the strength requirements of the equipment under various rescue scenarios and working conditions.
