Description

TECHNICAL FIELD

[0001] The present application relates to the technical field of steel coil transportation, in particular to a train steel coil transportation seat frame hoisting device. BACKGROUND

[0002] The steel coil transported by train needs to be placed on the transportation seat frame, which is provided with a plurality of triangular frame bodies, referred to as positioning frames (marked as b in the drawing, refer to Figure 1 ), for positioning the steel coil.

[0003] For the stability and safety of hoisting, the steel coil transportation seat frame (hereinafter referred to as seat frame, marked as a in the drawing) is generally hoisted horizontally. The hoisted seat frame often collides with the center beam (marked as c in the drawing, refer to Figure 2 ) of the carriage (the distance between the center beams of the train carriage is about 2910 cm, the width of the steel coil seat frame is 2890 cm, only a difference of about 10 cm), and a special person is needed to assist in the operation in the carriage during loading and unloading to adjust the position of the seat frame so that the seat frame can be normally loaded and unloaded without colliding with the center beam of the train carriage. Therefore, the existing steel coil seat frame loading and unloading method has the problems of low safety and low efficiency. CONTENT OF THE UTILITY MODEL

[0004] The purpose of the present application is to improve the problem that the existing steel coil seat frame is easy to collide with the center beam of the train carriage during loading and unloading in the train carriage, and the safety and efficiency of the seat frame loading and unloading are low. The present application provides a train steel coil transportation seat frame hoisting device.

[0005] The train steel coil transportation seat frame hoisting device provided by the present application adopts the following technical scheme:

[0006] A train steel coil transportation seat frame hoisting device, comprising

[0007] a lifting appliance, the lifting appliance being at least two;

[0008] The lifting appliance comprises a connecting portion, an eccentric portion and a hook body;

[0009] The connecting portion is used for connecting with the chain of the crane;

[0010] The eccentric portion is fixedly arranged at the bottom of the connecting portion, and an eccentric groove is formed at one side;

[0011] The hook body is fixedly arranged at the bottom of the eccentric groove and is upwardly inclined, and the upper surface is used for hooking the positioning frame of the seat frame;

[0012] The different positioning frames hooked by the plurality of hook bodies are located on the same side of the center of the seat frame.

[0013] By adopting the technical scheme, the hoisting device hoists the plurality of positioning racks on the same side of the center of the seat frame through the plurality of hooks, and in the process of moving the seat frame upward, the seat frame is kept in an inclined state due to being hoisted eccentrically, thereby reducing the probability of collision with the carbody center sill. The inclined arrangement of the hook body can be more stably abutted with the positioning rack in the inclined state when hoisted, and the probability of unhooking is reduced, and the stability of hoisting the seat frame is improved. Since the seat frame is in an inclined state when hoisted, the distance between the seat frame and the inner wall of the carbody is increased, and manual adjustment of the position of the seat frame in the carbody is not required, and the safety and loading and unloading efficiency of the seat frame in the carbody are improved.

[0014] Optionally, the upper surface of the hook body is provided with a protrusion, which can be in close contact with the top of the lower surface of the positioning rack after the seat frame is hoisted.

[0015] By adopting the technical scheme, the protrusion on the upper surface of the hook body can effectively increase the contact area with the positioning rack of the seat frame, thereby improving the stability of hoisting the seat frame.

[0016] Optionally, a reinforcing block is fixed between the upper surface of the hook body and the eccentric part.

[0017] After the seat frame is hoisted, the positioning rack abuts against the reinforcing block and does not contact the eccentric groove.

[0018] By adopting the technical scheme, the reinforcing block not only improves the connection strength of the hook body and the eccentric part, but also reduces the contact between the positioning rack and the eccentric part, thereby improving the stability of hoisting the seat frame.

[0019] Optionally, a locking groove is formed at the top end of the upper surface of the hook body, and an eccentric locking block is rotatably connected in the locking groove, the eccentric locking block is in an "L" shape, the rotation axis is located in the middle of the eccentric locking block, and the two ends are respectively a contact end and an intercept end.

[0020] The contact end is closer to the eccentric part than the intercept end, and the intercept end makes the contact end extend out of the top of the locking groove through gravity.

[0021] When the positioning rack of the seat frame abuts against the upper surface of the hook body, the contact end is pressed back into the locking groove, and at this time, the intercept end is rotated above the contact end and opposite to the positioning rack.

[0022] By adopting the technical scheme, when the positioning rack abuts against the contact end, the contact end is rotated downward, and when the positioning rack abuts against the hook body, the intercept end is rotated upward, thereby reducing the probability of the positioning rack slipping off the hook body through the intercept end, and improving the safety of hoisting.

[0023] Optionally, when the contact end is not in abutment with the positioning rack, the contact end is in a horizontal state.

[0024] By adopting the technical scheme, the contact end is in a horizontal state in a natural state, can be more conveniently and stably abutted against the positioning frame, and continuously places the positioning frame on the hook body during the lifting of the lifting appliance.

[0025] Optionally, the connection part is located on the side of the lifting appliance gravity center away from the eccentric part.

[0026] By adopting the technical scheme, when the lifting appliance lifts the seat frame with the positioning frame, the inclined state of the seat frame does not cause the lifting appliance to excessively rotate, thereby improving the stability of the lifting appliance in lifting the seat frame with the positioning frame.

[0027] Optionally, the multiple positioning frames hooked by the hook bodies of the multiple lifting appliances are opposite on the seat frame.

[0028] By adopting the technical scheme, after the seat frame is lifted, the inclined state of the seat frame is more stable.

[0029] Optionally, the multiple lifting appliances are fixedly connected with the cross beam between the connection parts, so that the multiple lifting appliances form an integral whole.

[0030] By adopting the technical scheme, the cross beam can make the multiple lifting appliances form an integral whole, thereby further improving the stability of the lifting of the seat frame.

[0031] In summary, the present application has at least one of the following beneficial technical effects:

[0032] 1. The seat frame is lifted by the multiple lifting appliances from the positioning frame, because the hooked positioning frames are located on the same side of the center of the seat frame and are opposite, the lifted seat frame is in an inclined state, the distance between the seat frame and the car center sill is reduced, the probability of contact between the seat frame and the car center sill is reduced, and thus additional personnel is not needed to adjust the position of the seat frame in the car, thereby improving the safety and efficiency of the loading and unloading of the seat frame in the train car.

[0033] 2. The lifting appliance is lifted by the hook body and the positioning frame, after lifting, because the seat frame is in an inclined state, the positioning frame is also in an inclined state, the inclined setting of the hook body can effectively fit the lower surface of the positioning frame and improve the contact area with the positioning frame, thereby improving the stability of the lifting of the seat frame.

[0034] 3. When the seat frame is lifted, the positioning frame abuts against the contact end and drives the contact end to rotate downward, the contact end is driven by the gravity of the seat frame to rotate upward to a position opposite to the side wall of the positioning frame, thereby protecting the positioning frame from being detached, and improving the safety of the lifting of the seat frame.

DETAILED DESCRIPTION

[0042] The following will be described in detail in combination with the accompanying Figures 3-6 The present application will be further described in detail.

[0043] The present application discloses a train steel coil transportation seat frame hoisting device.

[0044] Embodiment 1

[0045] Reference Figure 3 and Figure 4 The train steel coil transportation seat frame hoisting device includes at least two hoists 1, two in this embodiment. The hoist 1 includes a connecting part 11, an eccentric part 12 and a hook body 13. The eccentric part 12 is fixedly arranged at the bottom end of the connecting part 11, and an eccentric groove 121 is formed on one side thereof. The hook body 13 is fixedly arranged at the bottom of the eccentric groove 121 and is inclined upward, and the upper surface of the hook body 13 is used to hook the positioning frame b of the seat frame a. The connecting part 11 is used to be connected with the chain of the crane, and the connection position of the connecting part 11 and the chain of the crane is located on the side of the center of gravity of the hoist 1 away from the eccentric part 12. When the hoist 1 is hoisted empty, the hook body 13 will rotate upward to approach the connection position of the chain of the crane and the connecting part 11.

[0046] The upper surface of the hook body 13 is convex, which can be in contact with the top of the lower surface of the positioning frame b after the seat frame a is lifted. The upper surface of the hook body 13 and the eccentric part 12 are fixedly provided with a reinforcing block 132. After the seat frame a is lifted, the positioning frame b is in contact with the reinforcing block 132 and does not contact the eccentric slot 121. The hook body 13 is provided with an eccentric locking block 2, which can reduce the probability of the positioning frame b being disengaged when the seat frame a is lifted.

[0047] The positioning frame b of the seat frame a is lifted by the hook body 13 of the two lifting devices 1. The lifting position is set so that the seat frame a is in an inclined state after being lifted, thereby increasing the distance between the two sides of the seat frame a and the car center beam c, and manual adjustment of the position of the seat frame a in the car is not required. The probability of collision between the seat frame a and the car center beam c is reduced, and the safety and efficiency of loading and unloading the seat frame a in the train car are improved. The relative arrangement of the lifted positioning frame b can further improve the stability of the seat frame a in the inclined state being lifted upward (the force is more stable). The inclined arrangement of the hook body 13 and the shape of the upper surface of the hook body 13 can make the top of the lower surface of the positioning frame b in contact with the upper surface of the hook body 13 after the seat frame a is lifted, increase the contact area with the positioning frame b, and further improve the stability of the lifting of the seat frame a. In addition, the arrangement of the reinforcing block 132 can not only improve the connectivity of the hook body 13 and the eccentric part 12, but also reduce the contact between the positioning frame b and the eccentric part 12, reduce the contact force between the positioning frame b and the eccentric part 12 to make the positioning frame b deflect, and further reduce the probability of the contact area between the positioning frame b and the hook body 13, thereby improving the stability of the position of the positioning frame b after being lifted. The chain connection point of the connecting part 11 can make the lifting device 1 in an approximately vertical state after the seat frame a is lifted, thereby reducing the inclination angle of the lifting device 1 after being lifted, and further improving the safety of loading and unloading the seat frame a. The eccentric locking block 2 can effectively limit the lifted positioning frame b and reduce the probability of disengagement.

[0048] Reference Figure 5 The top end of the upper surface of the hook body 13 is provided with a locking slot 131, and the eccentric block is rotatably connected in the locking slot 131. The eccentric locking block 2 is "L" shaped, and the rotation shaft is located in the middle of itself, and the two ends are respectively a contact end 21 and an intercepting end 22. The contact end 21 is closer to the eccentric part 12 than the intercepting end 22, and the intercepting end 22 makes the contact end 21 extend out of the top of the locking slot 131 by gravity. When the positioning frame b of the seat frame a is in contact with the upper surface of the hook body 13, the contact end 21 is pressed back into the locking slot 131, and at this time the intercepting end 22 is rotated above the contact end 21 and opposite to the positioning frame b. When the contact end 21 is not in contact with the positioning frame b, the eccentric locking block 2 will make the contact end 21 in a horizontal state by its own gravity.

[0049] The shape and weight distribution of the eccentric locking block 2 are arranged so that the contact end 21 is in a horizontal state when the eccentric locking block 2 is in a natural state, so as to facilitate abutting with the top of the lower surface of the positioning frame b. In the process of lifting the seat frame a by the positioning frame b, the contact end 21 is abutted with the lower surface of the positioning frame b and rotated, so that the positioning frame b is abutted with the hook body 13, and the hook body 13 is attached with the lower surface of the positioning frame b after the seat frame a is lifted. In the process of rotating the abutting end, the intercepting end 22 is also rotated upward, so that the intercepting end 22 is opposite to the positioning frame b. Before the seat frame a is put down, the positioning frame b will not be separated from the hook body 13 due to the intercepting effect of the intercepting end 22.

[0050] The implementation principle of the embodiment 1 of the present application is that the multiple lifting devices 1 on the equipment lift multiple positioning frames b on the same side and opposite to the center point of the seat frame a. In the process of moving upward through the positioning frame b, the hook body 13 is abutted with the contact end 21 and drives the intercepting end 22 to rotate upward, so as to realize the automatic locking of the positioning frame b on the hook body 13. After the seat frame a is lifted, the seat frame a is in an inclined state, at this time, the bottom of the positioning frame b is attached with the hook body 13, so as to improve the stability of lifting the seat frame a. Since the seat frame a is in an inclined state when being lifted, the distance between the two ends of the seat frame a and the car body center beam c is increased, so that additional personnel is not needed to adjust the position of the seat frame a in the car body, and the safety and efficiency of loading and unloading the seat frame a in the car body are improved.

[0051] Embodiment 2

[0052] Reference Figure 6 The difference between the embodiment 2 and the embodiment 1 of the present application is that the connecting parts 11 of the multiple lifting devices 1 are fixedly connected with the cross beam 3, so that the multiple lifting devices 1 form an integral whole.

[0053] The difference between the implementation principle of the embodiment 2 of the present application is that the cross beam 3 connects the multiple lifting devices 1 into an integral whole, so as to limit the position between the lifting devices 1, which can further improve the efficiency of lifting the seat frame a and reduce the time of adjusting the position of the lifting device 1.

[0054] The embodiments of the specific implementation mode are the preferred embodiments of the present application, but do not limit the protection scope of the present application, so that: any equivalent changes made according to the structure, shape, principle of the present application should be covered in the protection scope of the present application.
