[0059] Please also read Figures 1 to 9, the hook lifting device provided by the present invention will now be described. The hook lifting device is applied to a railway vehicle, the vehicle body of the railway vehicle has an end beam 6, and a hook 7 is also provided on the vehicle body on the surface where the end beam 6 is located, and the hook lifting device includes an operating module 1, a hook lifting module 2 and a connecting rod assembly 3. The operating module 1 has an operating cross bar 11, and the operating cross bar 11 is arranged at the bottom of the end beam 6 along the width direction of the vehicle. The end of the operating cross bar 11 away from the hook 7 forms an operating end, and the other end forms a driving end. The operating cross bar 11 can rotate along its own axis on the end beam 6; the hook lifting module 2 is fixed above the end beam 6 corresponding to the hook 7, and the hook lifting module 2 has a hook lifting end connected to the hook opening device of the hook 7, and a driven end corresponding to the driving end; the connecting rod assembly 3 includes a first connecting rod 31, a connecting member 32 and a second connecting rod 31. The connecting rod 33, the first connecting rod 31 and the second connecting rod 33 are respectively distributed along the height direction of the vehicle body, and can swing in a vertical plane. One end of the first connecting rod 31 is fixedly connected to the driving end, and one end of the second connecting rod 33 is rotatably connected to the end beam 6. The two ends of the connecting member 32 are respectively hinged to the other ends of the first connecting rod 31 and the second connecting rod 33. The axis of the hinge shaft of the first connecting rod 31 and the connecting member 32 and the axis of the hinge shaft of the second connecting rod 33 and the connecting member 32 are both parallel to the operating cross bar 11.

[0060] It should be noted that the first connecting rod 31 and the connecting member 32, as well as the second connecting rod 33 and the connecting member 32, are rotatably connected via a round hole and round shaft cotter pin, which has a simple structure and is easy to disassemble, thus facilitating inspection and maintenance.

[0061] It should be noted that the hook lifting end is connected to the hook opening device of the coupler 7, and the hook opening device rises and the coupler 7 is opened.

[0062] It should be noted that the end beam 6 refers to the beam at the end of the railway vehicle underframe, and the coupler 7 is arranged on the end beam 6 .

[0063] It should be noted that, see Fig. 9 The railway vehicle is a rectangular structure, with the coupler and the end beam arranged on the side of the railway vehicle. The solid arrow indicates the length direction of the vehicle body, the hollow arrow indicates the width direction of the vehicle body, and the solid arrow indicates the height direction of the vehicle body.

[0064] In specific implementation, the connecting member 32 is a vertical rod, the driven end and the driving end are aligned in the up-down direction, and the two ends of the connecting member 32 are respectively hinged to the first connecting rod 31 and the second connecting rod 33. There are no complicated components and the cost is low.

[0065] Optional, see Figure 5 The connecting member 32 is an irregular rod body, and its two ends are respectively hinged to the first connecting rod 31 and the second connecting rod 33; the connecting rod 32 can also be a prismatic rod, as long as it is a rigid structure that can drive the first connecting rod 31 and the second connecting rod 33 to rotate synchronously.

[0066] It should be noted that, see Figure 3 There are multiple accessories on the end beam of the vehicle, refer to the shaded part in the figure. The space left for installing the hook device is very limited, and it is impossible to use the conventional method of connecting the hook chain with a driving rod.

[0067] It should be noted that the connection method between the first connecting rod 31 and the driving end of the operating cross rod 11 is coaxial clamping. A clamping hole is formed at the end of the first connecting rod 31. The clamping hole is a special-shaped hole. The driving end of the operating cross rod 11 is adapted to the clamping hole. The driving end passes through the clamping hole and is clamped with the clamping hole.

[0068] As another connection method between the first connecting rod 31 and the driving end of the operating cross bar 11 , the first connecting rod 31 and the operating cross bar 11 are fixed by welding.

[0069] Compared with the prior art, the hook lifting device provided by the present embodiment has a hook lifting module 2 installed above the end beam 6, an operating module 1 installed on the end beam 6, and a connecting rod assembly 3 used for transmission. The first connecting rod 31 and the second connecting rod 33 are longitudinally arranged so that the connecting member 32 leaves the plane where the end beam 6 is located. The first connecting rod 31 and the second connecting rod 33 cooperate to change the original planar linkage into a three-dimensional linkage, thereby avoiding interference of the components installed on the end beam 6 with the transmission of the connecting rod assembly 3. The operating module 1 and the hook lifting module 2 can be installed in the gap between the accessories, occupying a small space, and the transmission between the hook lifting module 2 and the operating module 1 is not limited by space. The present device has strong environmental adaptability, and the connecting components do not have complicated coordination, thereby reducing costs.

[0070] In some embodiments, see Figure 1 and Figure 3 The hook lifting module 2 includes two support seats 21, a rotating rod 22 and a hook lifting rod 23. The two support seats 21 correspond to the hooks 7 respectively and are fixed above the end beam 6; the rotating rod 22 is arranged along the width direction of the vehicle body and is hinged to the two support seats 21 respectively. One end of the rotating rod 22 close to the operating cross bar 11 passes through the support seat 21 and forms a driven end, which is fixedly connected to the second connecting rod 33; the hook lifting rod 23 extends longitudinally, one end of the hook lifting rod 23 is fixedly connected to the rotating rod 22, and the other end is connected to a chain 24, the bottom end of the chain 24 is connected to the hook opening device of the hook 7, and the chain 24 and the hook lifting rod 23 cooperate to form a hook lifting end.

[0071] During specific implementation, the two support bases 21 are integrated.

[0072] As an embodiment of the rotational connection between the second connecting rod 33 and the end beam 6, see Figure 1 The rotating rod 22 is rotatably connected to the support seat 21, the support seat 21 and the end beam 6 are fixedly connected, the second connecting rod 33 and the driven end are fixedly connected, and the second connecting rod 33 and the rotating rod 22 are fixedly connected.

[0073] It should be noted that the second connecting rod 33 and the driven end are connected in a coaxial clamping manner, and a clamping hole is formed at the end of the second connecting rod 33, and the driven end passes through the clamping hole and is clamped and matched with the clamping hole.

[0074] As another connection method between the second connecting rod 33 and the driven end, the second connecting rod 33 and the driven end are fixed by welding.

[0075] The hook lifting module 2 provided in this embodiment has a simple structure, no complex structure, and low manufacturing cost; only the support seat 21 is in contact with the upper end of the end beam, which occupies a small area and can adapt to limited space; through the rotation of the rotating rod 22, the hook lifting rod 23 is driven to make a circular arc motion around the axis of the rotating rod 22, so that the hook lifting end of the hook lifting rod 23 is lifted and lowered, and the chain 24 is driven to lift and lower, and finally the hook opening device of the coupler 7 is driven to lift and lower.

[0076] In some embodiments, see Figure 1 and Figure 3 The operation module 1 also includes a plurality of fixing seats 12, which are fixed on the end beam 6 at intervals along the lateral direction. Each fixing seat 12 has a jack that penetrates transversely. The operating crossbar 11 penetrates the plurality of jacks along a preset direction and rotates with the plurality of jacks. The plurality of fixing seats 12 provide installation positions for the operating crossbar 11. The plurality of jacks are coaxially arranged, which can guide the insertion direction of the operating crossbar 11 and ensure that the installed operating crossbar 11 is arranged in the horizontal direction. The fixing seats 12 are arranged at intervals, so that the operating crossbar 11 is away from the surface of the end beam 6, reducing the space occupied on the end beam. Only the fixing seats 12 are in contact with the end beam, avoiding interference of other components with the operating crossbar 11.

[0077] In some embodiments, see Figure 6 The end of the operating cross bar 11 away from the first connecting rod 31 is coaxially sleeved with a first gear 113, and the first gear 113 forms an operating end. A driving member 5 is provided on the end beam 6, and a second gear 51 is provided on the driving member 5. The axis of the rotating shaft of the second gear 51 is arranged along the width direction of the vehicle body, and a toothed chain 52 is sleeved on the second gear 51 and the first gear 113. The operating cross bar 11 is driven by the driving member 5 to realize rotation. The driving member 5 provides power to rotate the second gear 51. The toothed chain 52 is respectively engaged with the second gear 51 and the first gear 113 to realize the synchronous rotation of the second gear 51 and the first gear 113. The structure is simple, the automatic rotation of the operating cross bar 11 is realized, and the labor intensity is reduced. The staff can control the opening and closing of the driving member 5 in the operating room through wiring, which simplifies the operation and improves the efficiency.

[0078] In some embodiments, see Figure 1 and Figure 3The end of the operating cross bar 11 away from the coupler 7 is fixedly connected with a lifting rod 111, the lifting rod 111 is perpendicular to the operating cross bar 11, and the lifting rod 111 and the operating cross bar 11 form an operating end. As a way to manually operate the operating cross bar 11, the lifting rod 111 is connected to the operating cross bar 11, and the operating cross bar 11 is rotated by rotating the lifting rod 111, which is simple to operate and does not have a complex mechanical structure; the lifting rod 111 is connected to the operating cross bar 11, and does not occupy the space on the end surface of the end beam 6.

[0079] In some embodiments, see Figure 1 and Figure 2 The outer peripheral surface of the operating cross bar 11 is provided with an anti-jumping rod 112, which is perpendicular to the operating cross bar 11 and can swing in the up and down directions as the operating cross bar 11 rotates; the hook lifting device also includes an anti-jumping component 4, and the anti-jumping component 4 includes an anti-jumping seat 41, a cross bar 42 and a limiting rod 43. The anti-jumping seat 41 is fixed to the end beam 6 and corresponds to the operating end. The anti-jumping seat 41 has an anti-jumping space 411 for the anti-jumping rod 112 to pass through, and the side wall of the anti-jumping seat 41 is provided with a through opening 412 along the width direction of the vehicle body; the cross bar 42 passes through the opening 412 along the width direction of the vehicle body, and the cross bar 42 slides and rotates with the opening 412. The cross bar 42 has an anti-jumping state of extending into the anti-jumping space 411 and abutting against the lower surface of the anti-jumping rod 112, and the anti-jumping state of the cross bar 42 is in contact with the anti-jumping rod 112. 112 is misaligned so that the anti-jump rod 112 can swing normally in the up and down directions; the limiting rod 43 is perpendicular to each other and is arranged at the protruding end of the cross bar 42, and the anti-jump seat 41 is provided with a first limiting groove 413 and a second limiting groove 414 corresponding to the limiting rod 43, and the first limiting groove 413 and the second limiting groove 414 are arranged at intervals along the width direction of the vehicle body, and the limiting rod 43 can be engaged with the first limiting groove 413 or the second limiting groove 414.

[0080] It should be noted that during the hook lifting operation, the anti-jump rod 112 moves downward, and moves upward during resetting.

[0081] The anti-jump component 4 provided in this embodiment extends into the anti-jump space 411 through the cross bar 42, intercepts the anti-jump rod 112 above the cross bar 42, and prevents the anti-jump rod 112 from continuing to fall. The cross bar 42 and the top of the anti-jump space 411 cooperate to clamp the anti-jump rod 112, and the anti-jump rod 112 remains stationary. The anti-jump rod 112 is connected to the operating cross bar 11, and the operating cross bar 11 cannot rotate, so as to avoid the connection piece 32 falling under the influence of gravity in the anti-jump state, causing the operating cross bar 11 to rotate in the opposite direction, causing the entire device to sag and deform; the limit rod 43 is in the anti-jump state when the cross bar 42 is in the working anti-jump state. When in the jumping state, it can be engaged with the first limiting groove 413 to fix the cross bar 42, ensuring that the anti-jumping rod 112 is always intercepted above the cross bar 42. At the same time, the engaging and cooperating of the limiting rod 43 and the first limiting groove 413 can prevent the cross bar 42 from moving due to vibration during driving, resulting in the anti-jumping rod 112 and the cross bar 42 being misaligned, and the anti-jumping rod 112 returning abnormally; in the working state, the cross bar 42 and the second engaging groove 414 are engaged, and after the cross bar 42 is fixed, it always remains misaligned with the anti-jumping rod 111, thereby ensuring the normal operation of the hook.

[0082] It should be noted that the anti-jump seat 41 and the fixing seat 12 are installed at the bottom of the end beam 6 to adapt to the limited space on the end beam 6 as much as possible.

[0083] In some embodiments, see Figure 2 The anti-jump assembly 4 also includes a reset seat 44, which has a reset groove 441. The cross bar 42 passes through the reset groove 441 along the width direction of the vehicle body and extends into the anti-jump space 411. An elastic member 45 is provided in the reset groove 441 and is sleeved on the cross bar 42. One end of the elastic member 45 is connected to the side wall of the reset groove 441, and the other end is connected to the cross bar 42. The elastic member 45 is configured with a preload force to keep the cross bar 42 in an anti-jump state. When the cross bar 42 extends into the anti-jump space 411 to support the anti-jump bar 112, the limit rod 43 and the first limit groove 413 are engaged, and the elastic member 45 is in a relaxed state; when the hook lifting operation is required, the cross bar 42 is pulled outward along the width direction of the vehicle body, and the elastic member 45 is deformed, generating an elastic force that makes the cross bar 42 close to the anti-jump space 411. At this time, the limit rod 43 and the second limit groove 414 are engaged, and the elastic member 45 remains in a deformed state. When the staff takes the limit rod 43 out of the second limit groove 414, the elastic member 45 automatically resets, driving the cross bar 42 to extend into the anti-jump space, and the anti-jump rod 112 is clamped by the cross bar 42 and the anti-jump seat 41, ensuring that the operating cross bar 11 can maintain normal stillness and prevent the connecting member 32 from falling in the anti-jump state.

[0084] Optionally, the elastic member 45 is a spring, which has good deformation continuity and high strength, and meets the use requirements of the elastic member 45. Of course, the elastic member 45 can also be other components with good elasticity, such as a high-strength rubber sleeve. As long as it has high strength and a certain elasticity, it will not be listed here one by one.

[0085] In some embodiments, see Figure 2 The anti-jump seat 41 is also provided with an extension plate 46, which extends along the length direction of the vehicle body and is flush with the top of the anti-jump space 411; in the free state, the anti-jump rod 112 and the extension plate 46 are arranged in close contact. The anti-jump rod 112 and the lower surface of the extension plate 46 are in close contact. With the cooperation of the extension plate 46 and the cross bar 42, the anti-jump rod 112 is in a stationary state in the free state, which prevents the anti-jump rod 112 from continuously moving upward, and then the operating cross bar 11 will not continuously rotate, the first connecting rod 31 will not rotate downward, the connecting member 32 will not sag, and the entire device is in a positive position. The setting of the extension plate 46 can ensure that the connecting member 32 will not sag, thereby ensuring the use effect of the entire device.

[0086] In some embodiments, see Figure 7 , the operation module 1 has two groups, the connecting rod assembly 3 has two groups, and the two operation modules 1 and the two connecting rod assemblies 3 are symmetrically connected to the two sides of the hook lifting module 2. When two operation modules 1 are provided, the two operation modules 1 are connected to the hook lifting module 2 through the corresponding connecting rod assembly 3. During the specific operation, the staff can perform the hook lifting operation from both sides of the coupler 7, avoiding the safety hazard when the staff passes through the bottom of the coupler 7, and improving the safety during operation.

[0087] In some embodiments, see Figure 8 An extension rod 331 is provided at one end where the second connecting rod 33 is hinged with the connecting piece 32 and extends along the long axis direction of the second connecting rod 33. The extension rod 331 is coaxially arranged with the second connecting rod 33 and a lap groove 332 opening upward is provided on the extension rod 331. The hook module 2 includes two hook frames 25 and an I-shaped hook frame 26. The two hook frames 25 are respectively fixed to the end beams 6, and a matching rod is provided on the outer side of the hook frame 25. The matching rod is arranged along the width direction of the vehicle body, and the matching rod is fixedly connected to the second connecting rod 33, and the matching rod forms a driven end; the I-shaped hook frame 26 includes a first cross bar 261, a second cross bar 262 and a longitudinal bar 263 arranged therebetween, the first cross bar 261 is rotatably arranged on the inner side of the two hook frames 25 along the width direction of the vehicle body, the first cross bar 261 and the matching rod are arranged coaxially, the second cross bar 262 is arranged above the extension rod 331, and can overlap and cooperate with the overlapping groove 332, and one end of the longitudinal rod 263 connected to the second cross bar 262 extends along its own long axis direction and protrudes from the second cross bar 262, and the extended end of the longitudinal rod 263 forms a hook end.

[0088] It should be noted that the matching rod and the first cross bar 261 are coaxially arranged and do not interfere with each other.

[0089] This embodiment provides a hook lifting module 2, which is lifted by the connection member 32, driving the extension rod 331 to lift, and the second cross bar 262 cooperates with the overlap groove 332 of the extension rod 331, so that the second cross bar 262 rises with the extension rod 331, and when the second connecting rod 33 is provided on both sides, the lifting of any one of the two extension rods 331 can drive the second cross bar 262 to lift, so as to lift the hook end. The overlap of the second cross bar 262 and the overlap groove 332 enables the rotation of the single-side operation module 1 to drive the chain 24 to rotate, which is simple to cooperate, uncomplicated in structure, and shortens the maintenance time.

[0090] When the operation module 1 has two groups, there are the following three implementations:

[0091] The operating ends of the two operating modules 1 are both manually operated in cooperation with the operating cross bar 11 and the lifting rod 111 , and the staff can operate the lifting rod 111 on either side to perform the hook lifting operation.

[0092] The operating ends of the two operating modules 1 are both equipped with a driving member 5, and the operation is performed by synchronously rotating the first gear 113 and the second gear 51. The driving member 5 can be electrically connected to the control compartment. When one of the driving members 5 fails, the driving member 5 on the other side can still drive the hook lifting operation to proceed normally, thereby meeting the working requirements.

[0093] The operating end of one operating module 1 adopts a manual form in which an operating cross bar 11 and a lifting rod 111 cooperate. The operating end of the other operating module 1 adopts a driving member 5, and operates by synchronously rotating the first gear 113 and the second gear 51. This embodiment is manually and automatically integrated, and can be operated automatically by the driving member 51, and can also be operated by manually rotating the lifting rod 111. The second cross bar 262 overlaps with the overlapping groove 332, so that the movements of the operating modules 1 on both sides do not interfere with each other and do not affect each other, thereby increasing the convenience of the device.

[0094] The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. Any modifications, equivalent substitutions and improvements made within the spirit and principles of the present invention should be included in the protection scope of the present invention.
