Description

Technical Field

[0001] This invention relates to the field of quay crane technology, specifically to a quay crane gate boarding system and a quay crane having the same. Background Technology

[0002] Access to quay cranes (hereinafter referred to as quay cranes) is mainly achieved through two methods: elevators and portal ladder platforms. Typically, both methods are arranged on the same column of the quay crane portal frame on either the land or sea side, facilitating access for terminal personnel for maintenance or operation. Traditional quay crane access is primarily arranged on vertical columns or by adding elevator auxiliary support pipes, allowing the elevator to move vertically up and down along the centerline of the column (or elevator auxiliary support pipe).

[0003] However, due to the complex and varied requirements of quay crane equipment at the current docks, more and more quay crane columns are being used at an angle. In order to meet boarding requirements, additional elevator columns have been added to the design as elevator support and guidance devices. The addition of elevator columns has made the design more complex and increased manufacturing costs. Summary of the Invention

[0004] In view of this, the present invention provides a quay crane gate boarding system and a quay crane having the same, which has a simple and stable structure and effectively reduces manufacturing costs.

[0005] To solve the above-mentioned technical problems, the present invention adopts the following technical solution:

[0006] According to a first aspect of the present invention, a quay crane gate boarding system includes a gate frame comprising an upper crossbeam, a lower crossbeam, and inclined columns connecting the corresponding ends of the upper and lower crossbeams. The inclined columns are inclined from bottom to top towards the land side. The quay crane gate boarding system is used for mounting on the inclined columns of the gate frame. The quay crane gate boarding system includes:

[0007] An elevator assembly for vertical connection to the outside of the inclined column, the centerline of the elevator assembly being located on the land side of the centerline of the lower crossbeam at the bottom of the inclined column and on the sea side of the centerline of the upper crossbeam at the top of the inclined column.

[0008] A boarding platform, which is connected to the upper end of the inclined column, is located on the land side of the inclined column.

[0009] One end of the boarding platform is close to the elevator assembly, and the other end extends into the inside of the inclined column.

[0010] Furthermore, the elevator component includes:

[0011] An elevator track is vertically installed on one side of the inclined column, and the center line of the elevator track is located on the land side of the center line of the lower crossbeam at the bottom of the inclined column and on the sea side of the center line of the upper crossbeam at the top of the inclined column.

[0012] Multiple elevator brackets are connected sequentially on the elevator track, and the elevator track is connected to the inclined column through the elevator brackets;

[0013] An elevator car is movably mounted on the elevator track.

[0014] Furthermore, the elevator bracket includes:

[0015] A structural support frame, one end of which is used to connect to the inclined column;

[0016] An elevator track support frame, one end of which is connected to the structural support frame and the other end of which is connected to the elevator track.

[0017] Furthermore, the structural support frame includes a first connecting beam and a connecting plate connected to one end of the first connecting beam, wherein the first connecting beam is detachably connected to the inclined column through the connecting plate.

[0018] Furthermore, the elevator track support frame includes:

[0019] A pair of second connecting beams, one end of which is connected to the side of the first connecting beam;

[0020] A fixed crossbeam is provided, one side of which is connected to the other end of a pair of second connecting beams, and the other side is connected to the elevator track.

[0021] Furthermore, the boarding platform includes:

[0022] A platform support frame, which is used to connect to the inclined column;

[0023] The platform body is mounted on the platform support and is arranged along the route from the outer side of the elevator car's projection position to the land side of the inclined column and then to the inner side of the inclined column.

[0024] Furthermore, the platform support includes four supports, two of which are respectively used to connect to the inner and outer sides of the inclined column, and the other two are used to connect to the land side of the inclined column. The platform body is mounted on the four platform supports.

[0025] Furthermore, the boarding platform also includes a grid panel, which is laid on the platform body.

[0026] Furthermore, the boarding platform also includes a suspension beam, one end of which is connected to the inner side of the platform body near the inclined column, and the other end is used to connect to the bottom of the upper crossbeam.

[0027] A quay bridge according to a second aspect of the present invention includes:

[0028] A door frame, the door frame including an upper crossbeam, a lower crossbeam, and inclined columns connecting the corresponding ends of the upper crossbeam and the lower crossbeam;

[0029] A quay crane gate boarding system, wherein the quay crane gate boarding system is installed on the inclined column, and the quay crane gate boarding system is any of the quay crane gate boarding systems of the first aspect described above;

[0030] A driver's cab platform system, which is installed at the bottom of the upper crossbeam.

[0031] The above-described technical solution of the present invention has at least one of the following beneficial effects:

[0032] According to an embodiment of the present invention, the quay crane gate boarding system has two advantages. First, the elevator components and inclined columns are connected and installed in an alternating manner, which is stable and reliable. This ensures that the elevator components can operate vertically without the need for additional support structures (such as elevator auxiliary support pipes or columns) between the elevator components and the inclined columns. The structure is simple and effectively reduces manufacturing costs. Second, the boarding platform is located on the land side of the inclined columns. Based on the structure of the elevator components and inclined columns being connected in an alternating manner, the manufacturing cost of the support structure is effectively reduced compared to the original sea-side design.

[0044] To make the objectives, technical solutions, and advantages of the embodiments of the present invention clearer, the technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some, not all, of the embodiments of the present invention. All other embodiments obtained by those skilled in the art based on the described embodiments of the present invention are within the scope of protection of the present invention.

Terms such as "upper," "lower," "left," and "right" are used only to indicate relative positional relationships; when the absolute position of the described object changes, the relative positional relationship also changes accordingly.

[0046] The following section will first combine the appendix. Figure 1-2 Describe the door frame in detail.

[0047] like Figure 1 , Figure 2 As shown, the door frame includes an upper horizontal beam 1, a lower horizontal beam 2, and diagonal columns 3 connecting the upper and lower ends of the upper horizontal beam 1 and the lower horizontal beam 2, respectively. Specifically, as shown... Figure 1 As shown, Figure 1The left side of the central inclined column 3 is the land side, and the right side of the inclined column 3 is the sea side. The inclined column 3 is inclined towards the land side from bottom to top.

[0048] Below, in conjunction with the appendix Figure 1-7 A detailed description of the quay crane gate boarding system according to an embodiment of the present invention.

[0049] According to an embodiment of the first aspect of the present invention, a quay crane gate boarding system, such as Figure 1 , Figure 2 and Figure 3 As shown, the quay crane gate frame boarding system is used to install on the inclined column 3 of the gate frame. The quay crane gate frame boarding system may include: elevator assembly 100 and boarding platform 200.

[0050] The elevator assembly 100 is vertically connected to the outside of the inclined column 3. The center line of the elevator assembly 100 is located on the land side of the side center line of the lower crossbeam 2 at the bottom of the inclined column 3 and on the sea side of the side center line of the upper crossbeam 1 at the top of the inclined column 3.

[0051] The boarding platform 200 is used to connect to the upper end of the inclined column 3, and the boarding platform 200 is located on the land side of the inclined column 3.

[0052] One end of the boarding platform 200 is close to the elevator component 100, and the other end extends into the inside of the inclined column 3.

[0053] Specifically, according to the quay crane gate boarding system of the present invention, the elevator assembly 100 is vertically connected to the outside of the inclined column 3 on the gate frame. The center line 140 of the elevator assembly is located on the land side of the lower crossbeam side center line 21 of the lower crossbeam 2 and on the sea side of the upper crossbeam side center line 11 of the upper crossbeam 1. This makes the elevator assembly 100 staggered vertically when installed and connected to the inclined column 3, which is structurally stable and ensures that the elevator assembly 100 runs vertically. At the same time, it does not require the installation of additional support structures (such as elevator auxiliary support pipes or columns) between the elevator assembly 100 and the inclined column 3. The structure is simple and effectively reduces manufacturing costs.

[0054] When setting up the boarding platform 200 on the inclined column 3, the staggered structure of the elevator assembly 100 and the inclined column 3 is utilized. That is, the upper elevator assembly 100 is on the seaward side, and the inclined column 3 is on the landward side. The boarding platform 200 is set on the landward side of the inclined column 3, with one end close to the elevator assembly 100 to receive workers exiting the elevator assembly 100, and the other end extending into the inside of the inclined column 3, so that workers can reach the work area inside the inclined column 3 through the boarding platform 200. This changes the existing method of setting the boarding platform on the seaward side and reaching the work area by going around the elevator from the outside of the door frame, and avoids the installation of a relatively long reinforcing support structure, improving safety while reducing manufacturing costs.

[0055] In some embodiments, such as Figure 1 and Figure 4 As shown, the elevator assembly 100 may include: an elevator track 110, multiple elevator supports 120, and an elevator car 130.

[0056] The elevator track 110 is vertically installed on one side of the inclined column 3. The center line of the elevator track 110 is located on the land side of the side center line of the lower crossbeam 2 at the bottom of the inclined column 3 and on the sea side of the side center line of the upper crossbeam 1 at the top of the inclined column 3.

[0057] Multiple elevator brackets 120 are connected sequentially on the elevator track 110, and the elevator track 110 is connected to the inclined column 3 through the elevator brackets 120.

[0058] The elevator car 130 is movably mounted on the elevator track 110.

[0059] In other words, in the elevator assembly 100, the elevator track 110 is vertically connected to the outside of the inclined column 3. The center line of the elevator track 110, which is also the center line 140 of the elevator assembly, is located on the land side of the center line 21 of the lower crossbeam and on the sea side of the center line 11 of the upper crossbeam. This allows the upper and lower sides of the elevator track 110 to be connected to the inclined column 3 through the elevator bracket 120, which is simple and stable. This allows the elevator car 130 to run stably on the elevator track 110.

[0060] In some embodiments, such as Figure 3 and Figure 5 As shown, the elevator support 120 may include a structural support frame 121 and an elevator track support frame 122.

[0061] One end of the structural support frame 121 is used to connect the inclined column 3.

[0062] One end of the elevator track support frame 122 is connected to the structural support frame 121, and the other end is connected to the elevator track 110.

[0063] In other words, the elevator support 120 consists of two parts: a structural support frame 121 and an elevator track support frame 122. The structure is simple, which facilitates a reliable connection between the elevator track 110 and the inclined column 3.

[0064] In some embodiments, such as Figure 6 and Figure 7 As shown, the structural support frame 121 may include a first connecting beam 1211 and a connecting plate 1212 connected to one end of the first connecting beam 1211. The first connecting beam 1211 is detachably connected to the inclined column 3 through the connecting plate 1212.

[0065] Therefore, the first connecting beam 1211 is detachably connected to the inclined column 3 via the connecting plate 1212, which is convenient, reliable, and has low maintenance costs.

[0066] In some embodiments, such as Figure 5 , Figure 6 and Figure 7 As shown, the elevator track support frame 122 may include: a pair of second connecting beams 1221 and a fixed crossbeam 1222.

[0067] One end of a pair of second connecting beams 1221 is connected to the side of the first connecting beam 1211.

[0068] The connection position of a pair of second connecting beams 1221 on the side of the first connecting beam 1211 is adjustable relative to the connecting plate 1212, thereby accommodating different distances between the elevator track 110 and the inclined column 3.

[0069] One side of the fixed crossbeam 1222 is connected to the other end of a pair of second connecting beams 1221, and the other side is connected to the elevator track.

[0070] The elevator track 110 can be reliably connected and fixed by the fixed crossbeam 1222.

[0071] In some embodiments, such as Figure 3 As shown, the boarding platform 200 may include: a platform support 210 and a platform body 220.

[0072] The platform support 210 is used to connect to the inclined column 3.

[0073] The platform body 220 is mounted on the platform support 210, and the platform body 220 is set along the route from the outer side of the projection position of the elevator car 130 to the land side of the inclined column 3 and then to the inner side of the inclined column 3.

[0074] In other words, one end of the platform support 210 is connected to the inclined column 3 and extends towards the land side of the inclined column 3, and then the platform body 220 is installed on the platform support 210. Compared with installing the platform support 210 on the sea side of the inclined column 3, the platform body 220 is set up with shorter material length and higher safety.

[0075] In some embodiments, such as Figure 3 As shown, the platform support 210 may include four, two of which are connected to the inner and outer sides of the inclined column 3 respectively, and the other two are connected to the land side of the inclined column 3. The platform body 220 is mounted on the four platform supports 210. This makes the structure of the boarding platform 200 more stable.

[0076] In some embodiments, such as Figure 3As shown, the boarding platform 200 may also include a grid panel 230, which is laid on the platform body 220.

[0077] Therefore, the grating plate 230 has high strength and light structure. Setting the grating plate 230 on the platform body 220 makes the platform body 220 more durable and easier to install and disassemble.

[0078] In some embodiments, such as Figure 2 , Figure 3 As shown, the boarding platform 200 may also include a suspension beam 240, one end of which is connected to the inner side of the platform body 220 near the inclined column 3, and the other end is used to connect to the bottom of the upper crossbeam 1.

[0079] In other words, a hanging beam 240 is installed at one end of the platform body 220 extending inward toward the inclined column 3 to further enhance the stability of the platform body 220 structure.

[0080] In addition, such as Figure 1 As shown, the boarding system of the quay crane gate frame according to an embodiment of the present invention may further include a ladder 300, which is used to install on the outside of the inclined column 3 to ensure normal boarding operations when the elevator assembly 100 is damaged or under maintenance.

[0081] The quay bridge according to a second aspect of the present invention will now be described in detail.

[0082] According to a second aspect of the present invention, such as a quay bridge Figure 2 As shown, it may include: door frame, quay crane door frame boarding system and driver's cab platform system 4.

[0083] The door frame includes an upper horizontal beam 1, a lower horizontal beam 2, and inclined columns 3 connecting the corresponding ends of the upper horizontal beam 1 and the lower horizontal beam 2.

[0084] The quay crane gate boarding system is installed on the inclined column 3. The quay crane gate boarding system is the quay crane gate boarding system of any embodiment of the first aspect described above.

[0085] The driver's cab platform system 4 is installed at the bottom of the upper crossbeam 1.

[0086] Specifically, the quay crane has installed the aforementioned quay crane door frame boarding system on the inclined column 3 for boarding operations. Compared with the existing design, it simplifies the structure while ensuring stable elevator operation, high safety performance, and low manufacturing cost.

[0087] The above description represents the preferred embodiments of the present invention. It should be noted that those skilled in the art can make various improvements and modifications without departing from the principles of the present invention, and these improvements and modifications should also be considered within the scope of protection of the present invention.
