Description

Technical Field

[0001] The invention belongs to the technical field of detachable flip side walls, and in particular relates to a detachable flip side wall for a railway shared flat car. Background Art

[0002] The function of the side walls of railway shared flat cars is to prevent the goods from falling to the sides of the road when transporting bagged bulk goods (such as ballast, ore, etc.). At present, the side walls used in shared flat cars are not flippable. The square columns are inserted into the column plugs at the bottom of the flat car and locked. The side walls are then connected to the square columns by longitudinal steel wires to fix the side walls to the edge of the flat car. However, this installation method cannot be flexibly flipped and disassembled. The side walls can only be removed by removing the steel wires or by lifting to load and unload the goods. The operation is time-consuming and labor-intensive, which increases the manpower and material costs of loading and unloading goods. In addition, since the side walls fixed by the steel wires are not firm enough, there are safety hazards during driving. Summary of the invention

[0003] The present invention aims to provide a detachable and flippable side wall for a railway shared flat car, which can be flexibly flipped open and the side wall disassembly operation is simple and quick, thereby solving the problem that the side walls currently used in shared flat cars cannot be flipped and are only fixed by longitudinal steel wires, resulting in time-consuming and labor-intensive loading and unloading of goods, and safety hazards caused by the steel wire fixation.

[0004] To this end, the technical solution adopted by the present invention is: a detachable and flippable side wall for a railway shared flat car, comprising a side wall main body, a flippable and detachable mechanism installed at intervals along the outer side of the side wall main body, and a mounting socket located on the flat car body, wherein the flippable and detachable mechanism corresponds to the mounting socket one by one up and down, and the flippable and detachable mechanism comprises an upper mounting side panel symmetrically fixed on the side wall main body front and back, and a movable locking block and a lower mounting assembly that are both centrally located between the upper mounting side panels, the top of the movable locking block is hingedly installed on the side wall main body, and the bottom of the lower mounting assembly is inserted into the mounting socket and fixed in upper and lower limit positions, the bottom end of the movable locking block is coaxially hinged with the bottom of the upper mounting side panel and the top of the lower mounting assembly to form an upper hinge, and the bottom end of the upper mounting side panel is hinged with the top of the lower mounting assembly to form a lower hinge corresponding to the upper hinge up and down, when the hinge relationship of the upper hinge is released, the lower end of the movable locking block is free and cannot provide side wall supporting force, and the side wall main body flips outward from an upward upright state along the lower hinge to open.

[0005] As a preferred embodiment of the above scheme, the lower mounting assembly is a front-to-back symmetrical structure as a whole, and the lower mounting assembly includes an upper hinged movable latch parallel to the upper and lower parts, a lower hinged fixed latch, a centrally arranged "H"-shaped lower mounting plate, a limit baffle fixedly installed on the outer side of the "H"-shaped lower mounting plate, and a latch sleeve fixedly installed on the outer side of the limit baffle. The top of the movable lock block is hinged to the side wall body, and the bottom end falls into the upper notch of the "H"-shaped lower mounting plate. The two ends of the upper hinged movable latch pass horizontally through the bottom end of the movable lock block, the side plate of the "H"-shaped lower mounting plate, the limit baffle, After the upper side panel is installed, it is locked by a cotter pin, so that the side wall body is kept in an upright state by locking the upper and lower ends of the movable locking block; the two ends of the lower hinged fixed pin are horizontally passed through the "H"-shaped lower mounting plate side panel, the limit baffle, the pin sleeve, and the upper mounting side panel in turn and are locked by the cotter pin. When the upper hinged movable pin is pulled out, the side wall body is flipped outward with the center line of the lower hinged fixed pin as the axis. The structure is interlocked, so that the side wall can be flexibly flipped. When it is necessary to load and unload goods, it is only necessary to flip and open the side wall. The operation is simple and quick, and it effectively saves manpower and material resources.

[0006] Further preferably, the bottom end of the limit baffle abuts against the mounting socket, and the bottom end of the "H"-shaped lower mounting plate is horizontally provided with a pin through hole and is equipped with a mounting fixing pin, so as to achieve upper and lower limit fixation after the "H"-shaped lower mounting plate is inserted into the mounting socket.

[0007] Further preferably, the side wall body includes a wall panel and a wall frame installed along an edge of the wall panel, and the structure is reasonably designed.

[0008] Further preferably, the upper and lower parallel wall frames are welded with vertical lock block mounting plates against the sides corresponding to the movable lock blocks, and the vertical lock block mounting plates are provided with hinged ear seats at intervals at the front and rear of the top of the movable lock block, and the hinge is achieved by inserting the rod through the top of the movable lock block and the hinged ear seat, thereby ensuring the stability of the hinge and the reasonable structural design.

[0009] It is further preferred that when the side wall body is in an upward upright locked state, the upper hinge exceeds the top hinge of the movable locking block, so that the upper and lower locked movable locking blocks tend to be inclined outward and downward, which is equivalent to making an angle between the movable locking block and the side wall body, thereby forming a triangular support, ensuring that the support is strong and the design is ingenious.

[0010] Further preferably, the upper mounting side panel is welded to the wall panel, and the top end abuts against the wall frame at the upper edge, and the bottom is provided with a notch that fits with the wall frame at the lower edge, thereby increasing the contact surface with the side wall body, ensuring the welding firmness, and the structural design is reasonable.

[0011] Further preferably, the mounting socket as a whole adopts a square column structure penetrating from top to bottom, and reinforcing ribs are provided on the front and rear sides of the mounting socket, so that the structure is stable.

[0012] Beneficial effects of the present invention:

[0013] (1) Compared with the side walls currently used in shared flat cars, which cannot be flipped over and are only fixed by longitudinal steel wires, this solution uses a flip-able detachable mechanism installed on the outside of the side wall body and inserted into the installation socket for fixation, thereby connecting the side wall body to the flat car body. When the side wall body needs to be removed, it is only necessary to pull the flip-able detachable mechanism out of the installation socket. The installation and removal of the side wall body is simple. The flip-able detachable mechanism is installed at intervals along the front and rear of the outside of the side wall body to ensure the stability of the installation of the side wall body, effectively eliminating the safety hazard of the side wall body falling off due to excessive shaking during driving. The structure is interlocking and the design is reasonable.

[0014] (2) The bottom end of the movable locking block is coaxially hinged with the bottom of the upper mounted side panel and the top of the lower mounted component to form an upper hinge. The bottom end of the upper mounted side panel is hinged with the top of the lower mounted component to form a lower hinge corresponding to the upper hinge. When the hinge relationship of the upper hinge exists, the upper and lower ends of the movable locking block are limited, thereby supporting the side wall body to maintain an upright state. However, when the hinge relationship of the upper hinge is released, the lower end of the movable locking block is free and cannot provide support for the side wall. The side wall body can be flipped open along the lower hinge. The design is novel and the hinge relationship at the lower end of the movable locking block is cleverly used to realize the two states of the side wall from upright to flipped open. The flipping operation of the side wall body is simple and convenient, which effectively saves the manpower and material resources required for unloading, reduces the unloading cost, and is highly practical.

[0015] In summary, the present invention has the advantages of high stability in the installation of the side wall body, elimination of the safety hazard of the side wall body falling off, simple flipping and disassembly operation, and saving of manpower and material resources.

[0019] The present invention will be further described below by way of embodiments and in conjunction with the accompanying drawings:

[0020] Combination Figure 1 — Figure 3 As shown, a detachable flip side wall for a railway shared flat car is composed of a side wall body 1, a flip and detachable mechanism 2 installed at intervals along the outer side of the side wall body 1, and a mounting socket 4 located on the flat car 3 body.

[0021] The flippable detachable mechanism 2 corresponds to the mounting socket 4 in one-to-one correspondence up and down.

[0022] The flippable disassembly mechanism 2 is composed of an upper mounting side plate 21 symmetrically fixed to the side wall body 1 , a movable locking block 22 and a lower mounting assembly 23 both centrally located between the upper mounting side plates 21 .

[0023] The side wall body 1 is composed of a wall panel 11 and a wall frame 12 installed along the edge of the wall panel.

[0024] A vertical locking block mounting plate 121 is welded to the side of the upper and lower parallel wall frame 12 corresponding to the movable locking block 22 .

[0025] The vertical locking block mounting plate 121 is provided with hinged ear seats 122 at intervals in front and back corresponding to the top of the movable locking block 22 , and is hinged by inserting a rod through the top of the movable locking block 22 and the hinged ear seat 122 .

[0026] When the side wall body 1 is in an upward upright locked state, the upper hinge portion exceeds the top hinge portion of the movable locking block 22, so that the movable locking block 22 locked up and down tends to be outwardly and downwardly inclined.

[0027] The upper mounting side plate 21 is welded to the wall plate 11 , and the top of the upper mounting side plate 21 abuts against the wall frame 12 at the upper edge, and the bottom is provided with a notch that fits with the wall frame 12 at the lower edge.

[0028] The top end of the movable locking block 22 is hingedly mounted on the side wall body 1 .

[0029] After the bottom of the lower mounting assembly 23 is inserted into the mounting socket 4, the upper and lower limit positions are fixed.

[0030] The bottom end of the movable locking block 22 is coaxially hinged with the bottom of the upper mounting side plate 21 and the top end of the lower mounting assembly 23 to form an upper hinge.

[0031] The bottom end of the upper mounting side plate 21 is hinged to the top of the lower mounting assembly 23 to form a lower hinge corresponding to the upper hinge.

[0032] When the hinged relationship at the upper hinge is released, the lower end of the movable locking block 22 is free and cannot provide support force for the side wall, and the side wall body 1 is flipped outward from the upward upright state along the lower hinge to open.

[0033] The lower mounting assembly 23 is a front-to-back symmetrical structure as a whole.

[0034] The lower mounting assembly 23 is composed of an upper hinged movable latch 235 parallel to each other, a lower hinged fixed latch 234, a centrally arranged "H"-shaped lower mounting plate 231, a limit baffle 232 fixedly mounted on the outside of the "H"-shaped lower mounting plate 231, and a latch sleeve 233 fixedly mounted on the outside of the limit baffle 232.

[0035] The top end of the movable locking block 22 is hinged to the side wall body 1 , and the bottom end falls into the upper notch of the “H”-shaped lower mounting plate 231 .

[0036] The two ends of the upper hinged movable pin 235 horizontally pass through the bottom end of the movable locking block 22, the side plate of the "H"-shaped lower mounting plate 231, the limit baffle 232, and the upper mounting side plate 21 in sequence and are locked by the cotter pin, thereby locking the upper and lower ends of the movable locking block 22 to keep the side wall body 1 in an upright state.

[0037] The two ends of the lower hinged fixed latch 234 horizontally pass through the side plate of the "H"-shaped lower mounting plate 231, the limit baffle 232, the latch sleeve 233, and the upper mounting side plate 21 in sequence and are locked by the cotter pin.

[0038] When the upper hinged movable latch 235 is pulled out, the side wall body 1 is turned outwardly with the center line of the lower hinged fixed latch 234 as the axis.

[0039] A pin hole 236 is horizontally arranged at the bottom end of the “H”-shaped lower mounting plate 231 , and is equipped with a mounting fixing pin, so that the “H”-shaped lower mounting plate 231 can be fixed at upper and lower limits after being inserted into the mounting socket 4 .

[0040] The bottom end of the limiting baffle 232 abuts against the mounting socket 4 .

[0041] The mounting socket 4 as a whole adopts a square column structure penetrating from top to bottom, and reinforcing rib plates 41 are provided at the front and rear sides of the mounting socket 4 .

[0042] When the side wall body 1 needs to be installed, the two ends of the lower hinged fixed pin 234 are horizontally passed through the "H"-shaped lower mounting plate 231, the limit baffle 232, the pin sleeve 233, and the upper mounting side plate 21 in sequence, and then locked by the split pin. Then, the lower end of the "H"-shaped lower mounting plate 231 of the flippable detachable mechanism 2 is inserted from top to bottom into the mounting socket 4, and then the fixed pin is horizontally passed through the pin through hole at the bottom of the "H"-shaped lower mounting plate 231, so that the side wall body 1 is installed on the shared flat car 3.

[0043] When the side wall body 1 needs to be unloaded, it is only necessary to pull out the fixing pin passing through the bottom end of the "H"-shaped lower mounting plate 231, and then pull out the "H"-shaped lower mounting plate 231 as a whole from the mounting socket 4, thereby separating the side wall body 1 from the flat car 3.

[0044] When the side wall body 1 needs to be erected to transport goods, the upper hinged movable pin 235 needs to be horizontally passed through the bottom end of the movable locking block 22, the "H"-shaped lower mounting plate 231, the limit baffle 232, and the upper mounting side plate 21 and then locked by the cotter pin, so that the movable locking block 22 supports the side wall body 1.

[0045] When the side wall body 1 needs to be lowered for unloading the goods, it is only necessary to pull out the upper hinged movable latch 235 to free the lower end of the movable locking block 22 , and then the side wall body 1 is turned outward along the lower hinged fixed latch 234 to open.
