[0044] Firstly, the auxiliary tooling for disassembling the traveling mechanism of the trolley of the shore crane according to an embodiment of the present invention will be described in detail below with reference to the accompanying drawings.

[0045] According to the embodiment of the present invention, the auxiliary tooling for disassembling the trolley traveling mechanism of the quay crane is as follows: Figure 1 , 2 As shown, it may include: a pulley limiting mechanism 100 and a guide rail mechanism 200.

[0046] The pulley limiting mechanism 100 is used to be installed on the bottom surface of the lower crossbeam of the crane.

[0047] The guide rail mechanism 200 is movably connected to the pulley limiting mechanism 100, and the guide rail mechanism 200 is used to be installed on the trolley traveling mechanism, so that the trolley traveling mechanism can slide as a whole relative to the lower crossbeam of the crane for replacement and maintenance.

[0048] Specifically, according to the disassembly auxiliary tooling of the trolley traveling mechanism of the quay crane according to the embodiment of the present invention, a pulley limiting mechanism 100 is installed on the bottom surface of the lower crossbeam of the crane, and a guide rail mechanism 200 is installed on the trolley traveling mechanism, and the guide rail mechanism 200 is movably connected to the pulley limiting mechanism 100, so that the trolley traveling mechanism is movably connected to the lower part of the lower crossbeam of the crane through the disassembly auxiliary tooling, so that the trolley traveling mechanism as a whole can slide out from under the lower crossbeam of the crane for replacement, maintenance or modification. The disassembly auxiliary tooling has a simple structure, is easy to disassemble and assemble, can be reused and has high safety.

[0049] In some embodiments, Figure 1 , 3 As shown, the pulley limiting mechanism 100 may include: a limiting mechanism and a roller mechanism.

[0050] The limiting mechanism may include a first mounting seat 120, which is in the shape of a "door", and the top edge of the first mounting seat 120 is used to be detachably connected to the bottom surface of the lower crossbeam of the crane.

[0051] The roller mechanism is installed on one side of the inner portion of the first mounting seat 120 .

[0052] The guide rail mechanism 200 is disposed in the first mounting seat 120 and movably connected to the roller mechanism.

[0053] Specifically, the pulley limiting mechanism 100 includes a limiting mechanism and a roller mechanism. The limiting mechanism is a "door"-shaped first mounting seat 120. The top edge of the first mounting seat 120 is used to connect to the bottom surface of the lower crossbeam of the crane. The roller mechanism is installed on the inner side of the first mounting seat 120. Thus, the guide rail mechanism 200 is inserted into the first mounting seat 120 and movably connected to the roller mechanism, so that the guide rail mechanism 200 can slide reliably and stably relative to the pulley limiting mechanism 100.

[0054] In some embodiments, Figure 3 As shown, the limiting mechanism may further include a first fixing block 110 , which is used to be installed on the bottom surface of the lower crossbeam of the crane, and the first mounting seat 120 is detachably connected to the bottom surface of the lower crossbeam of the crane through the first fixing block 110 .

[0055] That is to say, by arranging the first fixing block 110 on the bottom surface of the lower beam of the crane to transitionally connect the first mounting seat 120 and the bottom surface of the lower beam of the crane, the connection is reliable and the disassembly and assembly are convenient, and the loss of the lower beam of the crane can also be reduced.

[0056] In some embodiments, Figure 3 As shown, the roller mechanism may include: a second mounting seat 130 and a roller 140 .

[0057] The second mounting seat 130 is mounted on one side of the interior of the first mounting seat 120 .

[0058] The roller 140 is rotatably mounted on the second mounting seat 130 in a horizontal direction, and the guide rail mechanism is disposed in the first mounting seat 120 and movably connected to the roller 140 .

[0059] That is to say, the second mounting seat 130 is installed on one side of the interior of the first mounting seat 120, and a roller 140 that can rotate horizontally is installed on the second mounting seat 130. The guide rail mechanism 200 passes through the interior of the first mounting seat 120 and contacts the roller 140 that can rotate horizontally, so that the guide rail mechanism 200 can slide reliably and stably relative to the pulley limiting mechanism 100. The structure is simple, the replacement and maintenance are convenient, and the production cost is low.

[0060] In some embodiments, Figure 3 As shown, the second mounting seat 130 is block-shaped, and one side of the second mounting seat 130 can be detachably connected to the inner side of the first mounting seat 120. A roller groove 131 is opened on the second mounting seat 130 toward the inside of the first mounting seat 120. A roller shaft 150 is passed through the roller groove 131 in the vertical direction, and the roller 140 is sleeved on the roller shaft 150.

[0061] Therefore, the roller mechanism has a simple structure, is convenient to disassemble and install, and is easy to replace and maintain.

[0062] In addition, an opening is provided at the end of the roller shaft 150 , and a clamping plate 160 is inserted into the opening, thereby facilitating the disassembly and installation of the roller shaft 150 .

[0063] In some embodiments, Figure 3 As shown, a side wall of the first mounting seat 120 away from the roller mechanism is shorter than another side wall of the first mounting seat 120 .

[0064] like Figure 2 , 3 As shown, the guide rail mechanism 200 may include: a plurality of second fixing blocks 210 and a guide rail body 220 .

[0065] Among them, a plurality of second fixing blocks 210 are used to be installed at intervals on the trolley traveling mechanism 500 and are located below a side wall of the first mounting seat 120 away from the roller mechanism.

[0066] The guide rail body 220 has an arched cross section. The guide rail body 220 is disposed in the first mounting seat 120 , and one outer side wall thereof is detachably connected to the plurality of second fixing blocks 210 in sequence, while the other outer side wall contacts the roller 140 .

[0067] Specifically, a side wall of the first mounting seat 120 away from the roller mechanism is shorter than the other side wall of the first mounting seat 120, and space can be left below the other side wall of the first mounting seat 120 for the second fixing block 210, and then the guide rail body 220 is arranged in the first mounting seat 120, one side of the guide rail body 220 is exposed and connected to the second fixing block 210, and the other side contacts the roller 140. The structure is simple and easy to implement.

[0068] In some embodiments, Figure 2 , 3 As shown, the guide rail mechanism 200 may further include a plurality of support blocks 230 , which are arranged relative to the second fixed block 210 and are sequentially installed on the trolley travel mechanism, and the support blocks 230 are connected to the bottom foot of the other outer side wall of the guide rail body 220 .

[0069] Specifically, a plurality of support blocks 230 are arranged on the other side relative to the second fixed block 210, and the support blocks 230 are connected to the base of the other outer wall of the guide rail body 220 to support and fix the guide rail body 220 together with the second fixed block 210, so as to prevent the guide rail body 220 from deformation and improve the service life of the guide rail body 220.

[0070] In some embodiments, Figure 2 , 3 As shown, the guide rail mechanism 200 may further include a plurality of adjustment blocks 240 , one end of the adjustment block 240 is connected to an outer side wall of the guide rail body 220 , and the other end is detachably connected to the second fixing block 210 .

[0071] That is to say, an adjustment block 240 is connected between an outer wall of the guide rail body 220 and the second fixed block 210 to adjust the position distance of the guide rail body 220 in the first mounting seat 120 relative to the roller 140 and the inner wall of the first mounting seat 120, so that the sliding of the guide rail body 220 relative to the pulley limiting mechanism 100 is more stable and reliable.

[0072] In addition, a reinforcing plate 250 may be connected to the bottom opening of the guide rail body 220 to enhance the structural strength of the guide rail body 220 .

[0073] In some embodiments, Figure 1 As shown, the disassembly auxiliary tooling may further include a support mechanism 300 , which is used to connect the end of the guide rail body 220 extending out of the trolley traveling mechanism 500 at one end and connect the end of the trolley traveling mechanism 500 at the other end.

[0074] That is, the end of the guide rail body 220 extending out of the trolley traveling mechanism 500 and the end of the trolley traveling mechanism 500 are connected through the supporting mechanism 300 to support the tail of the guide rail body 220 to prevent deformation.

[0075] In some embodiments, Figure 2 As shown, the support mechanism 300 may include: a first ear plate 310 , a second ear plate 320 and a support rod 330 .

[0076] The first ear plate 310 is used to be installed on the end of the guide rail body 220 extending out of the trolley traveling mechanism 500 .

[0077] The second ear plate 320 is used for being installed on the end of the trolley traveling mechanism 500 .

[0078] One end of the support rod 330 is connected to the first ear plate 310 , and the other end is connected to the second ear plate 320 .

[0079] That is to say, by respectively installing the first ear plate 310 and the second ear plate 320 on the end of the guide rail body 220 extending out of the trolley traveling mechanism 500 and the end of the trolley traveling mechanism 500, and connecting the support rod 330 therebetween, support can be achieved for the end of the guide rail body 220 extending out of the trolley traveling mechanism 500.

[0080] Next, combine Figure 4-Figure 5 The present invention describes the disassembly of the trolley traveling mechanism of the quay crane by using the auxiliary tooling for disassembly of the trolley traveling mechanism of the quay crane according to the embodiment of the present invention.

[0081] Figure 4 A schematic diagram showing the installation of the auxiliary tooling for disassembling the traveling mechanism of the trolley of the quay crane according to the embodiment of the present invention; Figure 5 A schematic diagram of the auxiliary tooling for disassembling the trolley traveling mechanism of a quay crane according to an embodiment of the present invention is shown when the trolley traveling mechanism is disassembled.

[0082] First, if Figure 4 As shown, the bottom of the lower crossbeam 400 of the crane is connected to a trolley traveling mechanism 500. When the trolley traveling mechanism 500 at the bottom needs to be replaced and repaired, a pulley limiting mechanism 100 is installed at the bottom of the lower crossbeam 400 of the crane, and a guide rail mechanism 200 is installed at the top of the trolley traveling mechanism 500. The overall sliding of the trolley traveling mechanism 500 relative to the lower crossbeam 400 of the crane is achieved through the movable connection between the pulley limiting mechanism 100 and the guide rail mechanism 200.

[0083] After slip, Figure 5 As shown, after the trolley traveling mechanism 500 has cleared the bottom position of the lower crossbeam 400 of the crane, the trolley traveling mechanism 500 is finally lifted and removed as a whole by the lifting device 600, so that the trolley traveling mechanism 500 can be maintained and replaced, which is convenient, fast and safe.

[0084] The above is a preferred embodiment of the present invention. It should be pointed out that for ordinary technicians in this technical field, several improvements and modifications can be made without departing from the principles of the present invention. These improvements and modifications should also be regarded as the scope of protection of the present invention.
