Description

Connecting part of container corner piece

Technical field

The invention relates to a connecting member for connecting upper and lower containers to each other when stacking containers, and in particular to a connecting member for a container corner piece.

Background technique

When a large number of containers are transported by ship, the containers stacked on top of each other are connected by a container connecting member, so that the cargo is not collapsed when the hull is shaken (rolled, pitched).

The invention patent application with the publication number CN104603030A discloses a connecting member for connecting two upper and lower stacked containers on a ship. As shown in Fig. 1, the container connecting member has an upper connection for engaging a bottom corner piece of the upper container. a protruding portion 10, and a lower connecting protrusion 11 that engages a corner piece of the lower container, and an impact baffle 12 is provided between the upper connecting protrusion 10 and the lower connecting protrusion 11, and the upper connecting protrusion 10 has an impact baffle The upper shank 13 has a head 14 on its opposite side of the impingement baffle 12. It can be easily discerned in Fig. 1 that the head 14 protrudes from the shank 13 on both sides thereof, thereby also forming the

locking projections

15 and 16. The lower connecting projection has a connecting flange 22 disposed laterally in the longitudinal direction of the container and a vertical rear wall 21 disposed on the back side of the connecting flange 22 of the lower connecting projection 11 such that the connecting flange 22 is The distance b between the edge 25 and the rear wall 21 is less than or equal to the width of the upper open elongated hole of the top corner piece, and the lower connecting protrusion 11 has a groove 26 extending in the groove shape through the entire length of the lower connecting protrusion 11 in the groove shape. .

As such a container connecting device, there is an automatic container connecting device in which the upper connecting protrusion 10 is previously mounted on the corner piece C of the lower portion of the container (the structure of the corner piece is as shown in FIG. 2), and the container is stacked to If the container is lowered and aligned with the lower container when the container is lower, the lower connecting protrusion 11 is automatically combined with the elongated hole of the corner piece of the lower container to perform the connection between the containers; on the contrary, when the container is unloaded The connection can be automatically released by lifting the container.

When the upper projection 10 and the bottom corner piece C are connected, as shown in FIG. 3, the lock firstly extends the locking projection 16 from the elongated hole of the bottom corner piece C into the inside of the corner piece C, since the locking projection 16 The length of the locking portion 15 is greater than the length of the locking projection 15 , and the spacing between the first inner wall C1 of the corner piece and the elongated hole C0 ensures that the locking projection 16 does not interfere with the first inner wall surface C1 after being inserted therein, therefore, the first The spacing between the inner wall surface C1 and the elongated hole C0 forms a seating position, and the locking projection 15 can also smoothly enter the inside of the corner piece C. However, if the lock first engages the locking projection 15 from the elongated hole of the bottom corner piece C into the corner piece The inside of the C, the locking projection 15 is from either end of the elongated hole, for example, as shown in FIG. 4, toward one end of the first inner wall surface C1, although between the first inner wall surface C1 and the elongated hole C0 The spacing also forms a seating position for the locking projection 15, and the locking projection 16 is clearly exposed to the outside of the corner piece C, so that the locking projection 16 cannot enter the inside of the corner piece C through the elongated hole. As shown in FIG. 5, another way is that the aspect in which the locking protrusion 15 enters the elongated hole faces the second inner wall surface C2, and when the locking protrusion 15 enters, it will interfere with the second inner wall surface C2, also causing the locking. The projection 16 cannot enter the outside of the corner piece C through the elongated hole. Therefore, the upper connecting projection 10 has only one direction inserted into the corner piece C, and also because of this, in order to prevent the assembler from inserting the upper connecting protrusion 10 into the corner piece C due to the reverse mounting during assembly, the impact is caused. The side of the baffle 12 is provided with a mark FRONT (front side). When assembling, the operator can judge the unique insertion direction after recognizing the FRONT. However, if the stacking of the container is at night, the assembler cannot smoothly recognize the FRONT. In this way, it is undoubtedly more time-consuming during the assembly process. However, the time that the cargo ship stays at the port is calculated in terms of time. According to the applicant, a 10,000 TEU ship has a net ton of about 66,000 net tons. The cost of parking at the port for one hour is (container ship 0.15 yuan / net ton / hour): 66000X0.15 = 9900 yuan, after parking the port, there are many other miscellaneous fees, such as: electricity supply, water supply fee, crane fee, dock Workers’ wages, etc., are linked to the time the boat is docked. Large ships of 10,000 TEU or more will be affected by the tides. If they are not loaded and unloaded within the expected time, and they cannot leave the port after the ebb tide, then they need to wait for the next high tide time, about 12 hours, compared to the 10,000 TEU ship. Said, the light parking fee will be 118,800 yuan more. Therefore, the above-mentioned connecting protrusions are bound to cause an increase in transportation costs due to structural reasons. At the same time, it also increases the labor intensity of the operators, and the operation work will be more mistakes when working in fatigue.

Summary of the invention

detailed description

The technology and performance of the present invention will be further described below with reference to the accompanying drawings and specific embodiments.

1, 6 to 9, the connecting member of the container corner member of the present invention includes an upper connecting protrusion 10 that engages the bottom corner piece C of the upper container; and a lower connecting protrusion 11 that engages the corner piece of the lower container An impact baffle 12 is provided between the upper connecting protrusion 10 and the lower connecting protrusion 11 . The upper connecting projection 10 has a shank 13 above the impingement baffle 12, the shank 13 having a head 14 on its opposite side of the impingement baffle 12, the head 14 being provided on both sides thereof to protrude from the shank a first locking projection 15 and a second locking projection 16 of 13, the spacing between the free end of the first locking projection 15 and the second locking projection 16 is greater than the diagonal of the elongated hole in the corner piece The length H0, but less than the sum of the length H0 of the diagonal of the elongated hole on the corner piece and the distance H1 between the first side wall of the elongated hole and the first inner wall surface C1 of the corner piece C, and less than or equal to the bottom The length H0 of the diagonal of the elongated hole in the corner piece is the sum of the distance H2 between the second side wall of the elongated hole and the second inner wall surface C2 of the corner piece C.

The side surface 15a of the first locking projection 15 and the side surface 16a of the second locking projection 16 are both curved surfaces, and preferably, the side surface 15a of the first locking projection 15 and the side surface 16a of the second locking projection 16 are formed by an elliptical surface. The contour of the side surface 15a and the side surface 16a is an elliptical arc surface. Therefore, the contour formed by the head portion 14, the first locking projection portion 15, and the second locking projection portion 16 is similar to that of the mango when viewed in a plan view. The outer contour, the outer contour of this shape, reduces the interference when inserted into the elongated hole of the corner piece C, and can more smoothly enter the inside of the corner piece. The upper surface and the lower surface of the first locking protrusion 15 and the second locking protrusion 16 are both planar, that is, the first locking protrusion 15 and the second locking protrusion 16 are both flat bodies, except that the side surface 15a and The side surface 16a is an elliptical curved surface.

The free end of the first locking protrusion 15 is provided with a first inclined surface 15b for inserting or withdrawing the first locking protrusion into the elongated hole C0 of the corner piece C, and the free end of the second locking protrusion 16 The second inclined surface 16b for inserting or withdrawing the second locking protrusion 16 into the elongated hole C0 of the corner piece C is provided, preferably, the freedom of the first locking protrusion 15 Only a part of the end is used to set the first inclined surface 15b instead of all along the free end, and similarly, only a part of the free end of the second locking protrusion 16 is used to set the second inclined surface 16b. Since the first locking protrusion 15 or the second locking protrusion 16 enters the inside of the corner piece C from the elongated hole C0, it is first inclined to the axis of the bottom corner piece C, and after entering, the upper connecting protrusion 10 The axis is parallel to the axis of the corner piece C, and therefore, the first inclined surface 15b and the second inclined surface 16b are disposed. The advantages of this setup are:

2 to 4, the connecting member of the present invention is inserted into the corner piece C in the manner and direction shown in Fig. 4. As can be seen from Fig. 4, the distance at which the corner piece C can be inserted is: H0+ H1, or: H0+H2, removing the length H0 of the diagonal of the elongated hole, the spacing H2 between the second side wall of the elongated hole and the second inner wall surface C2, which is significantly smaller than the first side wall of the elongated hole and the first The distance H1 between the inner wall surfaces C1 can be seen by means of FIG. 3, and the upper insertion protrusion 10 can smoothly enter the inside of the corner piece C with the insertion distance of H0+H1, which will not be described here. Take the available insertion distance of H0+H2 as an example:

With the state of FIG. 4, when the first locking projection 15 first obliquely enters along the first apex angle of the elongated hole C0, when the first inclined surface 15b comes into contact with the central portion of the side wall surface of the elongated hole C0, At the other end, the top of the second locking protrusion 16 substantially corresponds to the second apex angle of the elongated hole CO (the second apex angle is opposite to the first apex angle of two pairs), with the first locking protrusion The portion 15 continues to enter the inside of the corner piece C, and the first locking protrusion 15 forms a snap fit with a portion of the inner surface of the corner piece C (when the entirety of the connecting member is still inclined), due to the second inclined surface In the presence of 16b, the second locking projection 16 smoothly escapes the interference of the second apex angle and enters the inside of the corner piece C. Therefore, the arrangement of the above two inclined faces can shorten the effective spacing between the first locking projection 15 and the second locking projection 16 when inserted into the inside of the corner piece, so that the first lock is thus After the protrusion 15 first enters the inside of the corner piece C, or after the second locking protrusion 16 first enters the inside of the corner piece C, the other locking protrusion also avoids the diagonal interference of the elongated hole C0 and enters to the end. The inside of the corner piece C.

One end of the first inclined surface 15b is tangent to the lower surface 15c of the first locking protrusion 15, and one end of the second inclined surface 16b is tangent to the upper surface 16c of the second locking protrusion 16, such that the first inclination The face 15b and the second inclined face 16b are not actually at or completely at the same height position, and such height positions may be in a staggered relationship, for example, the first inclined face 15b and the second inclined face 16b partially overlap in the height direction. For example, the other end of the first inclined surface 15b (the other end is the end opposite to the tangent end) is 15 mm from the shank 13 and the other end of the second inclined surface 16b (the other end is opposite to the tangent end) The end portion is 12 mm from the height of the handle portion 13. Preferably, the height position is The other end of the first inclined surface 15b (the other end is the end opposite to the tangent end) and the other end of the second inclined surface 16b (the other end is the end opposite to the tangent end), for example, The other end of one inclined surface 15b has a height of 15 mm from the shank portion 13, and the other end of the second inclined surface 16b is also 15 mm from the height of the shank portion 13. The first inclined surface 15b and the second inclined surface 16b are parallel to each other in the lateral positional relationship.

After the first locking projection 15 and the second locking projection 16 sequentially enter the inside of the corner piece C, the Applicant has found that during actual transportation, when the ship is rocked by an external force, the container is also brought with the connecting member. The overall lateral displacement causes a metal collision sound between the connecting member and the corner piece C. In the case of long-term collision, the handle is easily deformed or even broken. If the handle 13 is broken, the result is that the ship is externally affected. The non-vertical impact forces cause the stacked containers to collapse. To this end, a fixing protrusion 13a is provided on the side wall surface of the handle portion 13, and the fixing protrusion portion 13a is directly below the first locking protrusion portion 15, and the width of the fixing protrusion portion 13a is smaller than the width of the first locking protrusion portion 15, when After the upper connecting protrusion 10 enters the inside of the corner piece C, the fixing protrusion 13a corresponds to the hole wall surface C3 of the elongated hole C0, and the sum of the width of the fixing protrusion 13a and the width of the shank 13 is smaller than the elongated hole. The width. After the fixing projection 13a is added, as shown in FIG. 10, between the fixing projection 13a and the elongated hole wall surface, or on the side wall surface and the elongated hole wall surface of the shank opposite to the other side of the fixing projection 13a. There is still a gap between them, but the spacing is much smaller than the spacing between the shank and the wall surface of the prior art, so that when the container is laterally displaced, the displacement distance is shortened, and the displacement of the container Both speed and kinetic energy are limited, effectively reducing the impact force on the handle.

The handle portion 13 has a rhombic cross section. As shown in FIG. 8, at least a portion of the apex angle of the handle portion 13 near the free end of the second locking projection 16 is truncated to form an upper connection protrusion 10 to be withdrawn from the bottom. The face 13b for giving way when the corner piece has an elongated hole. This surface is an inclined surface formed by cutting at an apex angle in the axial direction of the shank portion 13. When the connecting member is pulled out from the corner piece 10, the face 13b can avoid the interference formed between the shank and the corner piece C, facilitating the smooth extraction of the connecting member from the corner piece 10.

The impact baffle 12 is provided with a notch 12a for indicating the direction in which the head is previously advanced before inserting the head 14 into the elongated hole of the corner piece. Since the presence of the notch is easy to observe directly, the assembler knows at a glance how to assemble the upper connecting projection 10 and the corner fitting C in a specific direction, unlike the connecting members of the prior art, on the side wall surface. The FRONT logo is set, and the assembler needs to find the logo to know that the connection protrusion 10 is inserted into the inside of the corner piece C in a specific direction. Therefore, the notch 12a has the advantages of time saving and economy, and in addition, after the gap is provided, there is an advantage of saving materials and reducing manufacturing costs.

The structure of the lower connecting protrusion 11 can be implemented like the shape and structure of FIGS. 6 to 8 in the present invention. It can also be implemented by a patent application as disclosed in the publication No. CN104603030A, and can also be implemented by a patent application as disclosed in the publication No. CN101027233A, which is not described herein again.

The above is only the embodiment of the present invention, and thus does not limit the scope of the patent of the present invention. Any equivalent structure or equivalent process transformation made by using the contents of the specification of the present invention, or directly or indirectly applied to other related technical fields, The same is true of the scope of patent protection of the present invention.
