Description

Technical Field

[0001] The present application relates to the technical field of shipping, and more particularly, to a lock head and a lock. Background Art

[0002] A lock is a type of "navigation structure". Due to the regulation of water flow, canalization of navigation, and limitations of terrain conditions and water surface slopes in natural rivers, a stepped longitudinal section must be formed to create a concentrated water surface drop. Therefore, special navigation structures must be used to allow ships to pass directly through the drop. The most commonly used modern navigation structure is a lock. The main body of a lock usually consists of an upper lock head, a lower lock head, and a lock chamber. According to the principle of communicating vessels, by opening and closing the filling and discharging valves, the water level in the lock chamber is regulated to achieve the stepped lifting of the ships in the lock chamber, overcoming the navigation difficulties caused by the water level drop in the waterway. However, in recent years, the trend of ship enlargement has become increasingly obvious, and in order to protect the propellers of ships, mud dragging facilities have been generally added to the bottoms of ships, further increasing the draft depth of the ships. As a result, when ships pass through the lock heads of existing locks, they often collide with the lock heads, causing damage to the lock heads under long-term collisions, greatly affecting the navigation safety and structural safety of the locks.

[0040] Embodiment

[0041] The embodiment of the present application provides a lock head 100, which can improve the problem that the lock head of the existing lock often collides with the bottom of the ship when the ship passes through the lock head, resulting in damage to the lock head under long-term collisions, and further greatly affecting the navigation safety and structural safety of the lock. The specific structure of the lock head 100 will be elaborated in detail below with reference to the accompanying drawings.

[0042] Combined with Figure 1 and Figure 2As shown in the figure, the lock head 100 includes a bottom slab 10, a gate 20 and two side piers 30. The bottom slab 10 extends along the first preset direction X. The side piers 30 extend along the second preset direction Y, and the two side piers 30 are respectively connected to both ends of the bottom slab 10 in the first preset direction X. The bottom slab 10 and the two side piers 30 enclose a gate chamber 40. The gate 20 is movably arranged on the side piers 30, and the gate 20 is used to open or close the gate chamber 40. Among them, a groove 11 is formed at the top of the bottom slab 10, and both ends of the groove 11 penetrate through both sides of the bottom slab 10 in the third preset direction Z respectively. The first preset direction X, the second preset direction Y and the third preset direction Z are perpendicular to each other in pairs.

[0043] The lock head 100 is provided with a bottom slab 10 and two side piers 30. The bottom slab 10 and the two side piers 30 enclose a gate chamber 40 for ships to pass through. The gate 20 arranged on the side piers 30 can open or close the gate chamber 40. By forming a groove 11 at the top of the bottom slab 10 and making both ends of the groove 11 penetrate through both sides of the bottom slab 10 in the third preset direction Z respectively, it is convenient for ships to pass through and prevent the ships from colliding with the bottom slab 10 of the lock head 100 when passing through the lock head 100. The lock head 100 with this structure avoids the phenomenon that ships with a draft depth exceeding the sill depth of the lock head 100 touch the bottom and collide when passing through the lock head 100, thus eliminating the hidden danger of damage to the bottom slab 10 under long-term collision, and further ensuring the navigation safety of ships and the structural safety of the lock head 100.

[0044] Among them, the bottom slab 10 and the two side piers 30 are of an integral structure, and the side piers 30 are of a concrete and steel structure.

[0045] In this embodiment, in combination Figure 1 and Figure 3 As shown in the figure, the bottom slab 10 includes a bottom slab body 12 and a reinforcing plate 13. An installation groove 121 is formed at the top of the bottom slab body 12, and the reinforcing plate 13 is laid on the bottom wall of the installation groove 121. The upper surface wall of the reinforcing plate 13 forms the bottom wall of the groove 11. By laying the reinforcing plate 13 on the bottom wall of the installation groove 121 of the bottom slab body 12 to form the bottom wall of the groove 11, the bottom slab body 12 is protected, the wear resistance of the bottom wall of the groove 11 is improved, and the service life of the bottom slab 10 is extended.

[0046] Among them, the bottom slab body 12 is of a concrete structure, and both ends of the bottom slab body 12 in the first preset direction X are integrally cast with the two side piers 30.

[0047] Exemplarily, the reinforcing plate 13 is a steel plate.

[0048] Furthermore, the bottom plate 10 includes two anchoring devices 14. The two anchoring devices 14 are respectively arranged on both sides of the reinforcing plate 13 in the first preset direction X. The anchoring device 14 is installed in the installation groove 121. The anchoring device 14 has an outer surface wall 141, and the outer surface wall 141 forms the groove side wall of the groove 11. Two groups of first steel bars 122 are embedded in the bottom plate body 12. The two groups of first steel bars 122 are respectively located on both sides of the groove 11 in the first preset direction X. The first steel bar 122 is connected to the reinforcing plate 13 through the anchoring device 14.

[0049] Anchoring devices 14 are arranged on both sides of the reinforcing plate 13 in the first preset direction X, and the anchoring device 14 has an outer surface wall 141 to form the groove side wall of the groove 11, thereby enhancing the wear resistance of the groove side wall of the groove 11. In addition, both sides of the reinforcing plate 13 are fixedly connected to the first steel bars 122 embedded in the bottom plate body 12 and located on both sides of the groove 11 through the corresponding anchoring devices 14, so that the reinforcing plate 13 and the first steel bars 122 form an integral structure, thereby increasing the structural strength of the bottom plate 10.

[0050] Wherein, each group of first steel bars 122 is multiple.

[0051] In some embodiments, the anchoring device 14 includes an anchor 142 and a pouring layer 143. The anchor 142 is arranged in the installation groove 121. Both the reinforcing plate 13 and the first steel bar 122 are fixedly connected to the anchor 142. The pouring layer 143 is poured on the outside of the anchor 142.

[0052] The anchoring device 14 is provided with an anchor 142 and a pouring layer 143. The reinforcing plate 13 is fixedly connected to the first steel bar 122 through the anchor 142, and is poured on the outside of the anchor 142 through the pouring layer 143, so that the anchor 142 is embedded in the pouring layer 143. The anchoring device 14 with this structure forms a stable anchoring system, thereby improving the reliability and stability among the reinforcing plate 13, the first steel bar 122 and the anchoring device 14.

[0053] Exemplarily, the material of the pouring layer 143 is epoxy mortar. The epoxy mortar is poured on the outside of the anchor 142 to fill the gap between the anchor 142 and the bottom plate body 12 and embed the anchor 142 in the pouring layer 143. In other embodiments, the pouring layer 143 can also be concrete.

[0054] Among them, in combination with Figure 2 , Figure 3 and Figure 4As shown, the anchor 142 includes a first connecting plate 1421 and a plurality of second connecting plates 1422 fixedly connected to the first connecting plate 1421. The first connecting plate 1421 is arranged in parallel with the reinforcing plate 13. One end of the first connecting plate 1421 in the first preset direction X is fixedly connected to one end of the reinforcing plate 13 in the first preset direction X. The first connecting plate 1421 has opposite first side 1421a and second side 1421b in the second preset direction Y. The plurality of second connecting plates 1422 are arranged at intervals along the third preset direction Z on the first side 1421a. The second connecting plates 1422 are perpendicular to the first connecting plate 1421, and the first steel bar 122 is fixedly connected to the second connecting plates 1422.

[0055] By fixedly connecting a plurality of second connecting plates 1422 to the first side 1421a of the first connecting plate 1421, the second connecting plates 1422 are perpendicular to the first connecting plate 1421, and the plurality of second connecting plates 1422 are arranged at intervals along the third preset direction Z, so that the first steel bar 122 can be connected to the second connecting plates 1422 of the anchor 142, and the reinforcing plate 13 can be connected to the first connecting plate 1421 of the anchor 142, thereby realizing the connection between the reinforcing plate 13 and the first steel bar 122 through the anchor 142. In addition, the anchor 142 with this structure has greater structural strength and higher stability.

[0056] Exemplarily, both the first connecting plate 1421 and the second connecting plates 1422 are steel plates, and the second connecting plates 1422 are welded to the first side 1421a of the first connecting plate 1421.

[0057] Exemplarily, the first steel bar 122 is fixedly connected to the second connecting plates 1422 by welding. In other embodiments, the first steel bar 122 can also be fixedly connected to the second connecting plates 1422 by bolt screwing.

[0058] It should be noted that, as shown in combination with Figure 3 and Figure 5 One end of the first connecting plate 1421 in the first preset direction X abuts against one end of the reinforcing plate 13 in the first preset direction X, and the first connecting plate 1421 is fixedly connected to the reinforcing plate 13 by welding with a weld seam. In other embodiments, the first connecting plate 1421 can also be fixedly connected to the reinforcing plate 13 by bolt screwing.

[0059] Furthermore, in combination with Figure 2 , Figure 3 and Figure 4As shown, the anchor 142 further includes a bent plate 1423 and a plurality of third connecting plates 1424. One end of the bent plate 1423 is fixedly connected to the second side 1421b, and the bent plate 1423 extends along the third preset direction Z. The plurality of third connecting plates 1424 are arranged at intervals along the third preset direction Z between the first connecting plate 1421 and the bent plate 1423, and both the first connecting plate 1421 and the bent plate 1423 are fixedly connected to the third connecting plates 1424.

[0060] By fixedly connecting the bent plate 1423 to the second side 1421b of the first connecting member, a tenon structure is formed at the bottom of the anchor 142, thereby ensuring the effective anchoring of the anchoring device 14 and increasing the connection reliability between the anchoring device 14 and the bottom plate body 12. In addition, the bent plate 1423 extends along the third preset direction Z, and a plurality of third connecting plates 1424 are arranged at intervals along the third preset direction Z between the bent plate 1423 and the first connecting plate 1421, thereby strengthening the connection strength between the bent plate 1423 and the first connecting plate 1421, and further increasing the structural strength of the anchor 142.

[0061] Exemplarily, both the bent plate 1423 and the third connecting plates 1424 are steel plates. The bent plate 1423 is welded to the second side 1421b of the first connecting plate 1421, and the third connecting plates 1424 are fixedly connected to the bent plate 1423 and the second side 1421b of the first connecting plate 1421 by welding.

[0062] It should be noted that, as Figure 4 shown, the bent plate 1423 can be an integral structure or a split structure. The bent plate 1423 can be formed by stamping a steel plate into a bent structure, or can be formed by welding two steel plates to each other. In this embodiment, the bent plate 1423 is an integral structure.

[0063] Optionally, as shown in combination with Figure 3 and Figure 5 shown, the reinforcing plate 13 and the anchor 142 are both arranged on the bottom wall of the installation groove 121, and both between the reinforcing plate 13 and the bottom wall of the installation groove 121 and between the anchor 142 and the bottom wall of the installation groove 121 are connected by an adhesive layer 15.

[0064] Among them, the adhesive layer 15 is a structural adhesive. Exemplarily, the structural adhesive can be one of epoxy resin structural adhesives, polyurethane structural adhesives, or anaerobic adhesive structural adhesives, etc.

[0065] In this embodiment, continuing to combine Figure 3 and Figure 5 shown, a second steel bar 16 is arranged in the bottom plate body 12. The second steel bar 16 extends along the second preset direction Y, and one end of the second steel bar 16 penetrates through the bottom wall of the installation groove 121 and is fixedly connected to the reinforcing plate 13.

[0066] A second steel bar 16 is further disposed in the bottom plate body 12, and the second steel bar 16 extends along the second preset direction Y. That is to say, the second steel bar 16 is implanted in the bottom plate body 12, and the second steel bar 16 is fixedly connected to the reinforcing plate 13, thereby further strengthening the structural stability between the reinforcing plate 13 and the bottom plate body 12 and improving the structural strength of the bottom plate 10.

[0067] Wherein, there are multiple second steel bars 16, and the multiple second steel bars 16 are arranged at intervals in the bottom plate body 12.

[0068] Furthermore, a plurality of through holes are formed in the reinforcing plate 13, and each second steel bar 16 is inserted into the corresponding through hole and welded to the reinforcing plate 13.

[0069] Exemplarily, after the second steel bar 16 penetrates into the through hole, it is fixedly connected to the reinforcing plate 13 by plug welding.

[0070] In summary, the construction process of the bottom plate 10 is as follows: Combining Figure 1 and Figure 3 as shown, first, an installation groove 121 is formed in the bottom plate body 12, and the first steel bar 122 embedded in the bottom plate body 12 is cut off so that the first steel bar 122 forms two groups of first steel bars 122 located on both sides of the installation groove 121. Then, second steel bars 16 are implanted at the position of the bottom plate body 12 corresponding to the installation groove 121, and structural adhesive is applied to the bottom wall of the installation groove 121. After that, the reinforcing plate 13 is bonded to the bottom wall of the installation groove 121 and each second steel bar 16 is inserted into the corresponding through hole on the reinforcing plate 13. At the same time, the anchor 142 is bonded to the bottom wall of the installation groove 121. After the reinforcing plate 13 is bonded to the bottom wall of the installation groove 121, the reinforcing plate 13 and the second steel bar 16 are fixedly connected by plug welding. Then, the anchors 142 arranged on both sides of the reinforcing plate 13 in the first preset direction X are welded to the reinforcing plate 13 and the corresponding first steel bars 122. Finally, the pouring layer 143 is poured outside the anchor 142, that is, epoxy mortar is poured outside the anchor 142 and the gap between the anchor 142 and the bottom wall body is filled.

[0071] In this embodiment, combining Figure 1 and Figure 6 , a protruding portion 21 matching the groove 11 is provided at the bottom of the gate 20. The protruding portion 21 is used to be inserted into the groove 11 to block the groove 11. By providing the protruding portion 21 matching the contour of the groove 11 at the bottom of the gate 20, the protruding portion 21 of the gate 20 can be inserted into the groove 11 when the gate 20 closes the cavity 40 to block the groove 11, thereby preventing water flow from leaking out of the groove 11. This structure is simple and convenient for transformation and implementation.

[0072] Exemplarily, the material of the gate 20 is steel.

[0073] Exemplarily, the protrusion 21 is fixedly connected to the bottom of the gate 20 by welding, so as to facilitate the transformation of the original gate 20 and reduce the manufacturing cost. In other embodiments, the protrusion 21 can also be connected to the bottom of the gate 20 by means of bolt screwing or the like.

[0074] Furthermore, in combination with Figure 6 、 Figure 7 and Figure 8 as shown, a water stop strip 22 is provided on the protrusion 21. When the protrusion 21 is inserted into the groove 11, the water stop strip 22 can seal the gaps between the protrusion 21 and the bottom wall and side wall of the groove 11, so as to improve the sealing performance between the protrusion 21 and the bottom wall and side wall of the groove 11.

[0075] Exemplarily, the material of the water stop strip 22 is rubber.

[0076] Exemplarily, the water stop strip 22 is connected to the protrusion 21 by means of bolt screwing.

[0077] Optionally, in combination with Figure 1 、 Figure 2 and Figure 9 as shown, the gate 20 is movably arranged on the side pier 30 along the second preset direction Y. Rollers 23 are arranged at both ends of the gate 20 in the first preset direction X. Guide inclined surfaces 41 for the corresponding rollers 23 to abut against are arranged on both opposite side walls of the gate cavity 40 in the first preset direction X.

That is to say, guide inclined surfaces 41 for the corresponding rollers 23 to abut against are arranged on both side piers 30. Thus, the two relatively arranged guide inclined surfaces 41 can play a guiding role on the gate 20 when the gate 20 moves relative to the side pier 30, reduce the crosstalk space of the gate 20 in the first preset direction X, so as to ensure that the protrusion 21 of the gate 20 can be accurately inserted into the groove 11, prevent the situation that the protrusion 21 of the gate 20 cannot be effectively positioned, and further realize the sealing effect on the groove 11.

[0079] Exemplarily, the guide inclined surface 41 is a wedge-shaped plate arranged on the side wall of the gate cavity 40. The wedge-shaped plate is bonded to the side wall of the gate cavity 40, and the wedge-shaped surface of the wedge-shaped plate forms the guide inclined surface 41 for the corresponding roller 23 to abut against.

[0080] Optionally, as shown in Figure 6As shown, two rollers 23 are provided at both ends of the gate 20 in the first preset direction X, and the two rollers 23 at one end of the gate 20 in the first preset direction X are arranged at intervals in the second preset direction Y.

[0081] In this embodiment, in combination with Figure 2 and Figure 9 As shown, the lock head 100 further includes a driving mechanism. The driving mechanism is installed above the gate 20 and is used to drive the gate 20 to move relative to the side pier 30 in the second preset direction Y. Guide grooves are provided on the two opposite side walls of the gate chamber 40 in the first preset direction X, and both ends of the gate 20 in the first preset direction X are movably inserted into the corresponding guide grooves respectively.

[0082] Exemplarily, the driving mechanism is a winch. The winch is provided above the gate 20, and the gate 20 is connected to the steel wire of the winch to drive the gate 20 to move through the winch.

[0083] In addition, the embodiment of the present application further provides a lock, including the above-mentioned lock head 100. The lock with such a lock head 100 can prevent a ship with a further increased draft from colliding with the lock head 100 when passing through the lock, thereby avoiding damage to the lock head 100 under long-term collision, and further improving the navigation safety and structural safety of the lock.

[0084] Among them, there are two lock heads 100, and the two lock heads 100 are arranged at intervals in the third preset direction Z, which are respectively the upper lock head and the lower lock head of the lock. The lock further includes a lock chamber extending in the third preset direction Z, and the upper lock head and the lower lock head are respectively provided at both ends of the lock chamber in the third preset direction Z.
