Description

Technical Field

[0001] This utility model relates to the field of transportation equipment technology, and in particular to a telescopic boom transportation tool for a front-mounted crane. Background Technology

[0002] The reach stacker is a port machinery product, weighing 76 tons, measuring 11 meters long, 4.1 meters wide, and 4.7 meters high. Exporting the entire unit is limited by shipping schedules and port handling capacity. Transporting such large items requires time for permit applications and route planning, impacting the overall project schedule. Therefore, to ensure rapid shipment of the reach stacker, it needs to be disassembled. The 11-meter-long telescopic boom of the lifting system must be disassembled and shipped separately. The telescopic boom is mostly a hollow steel structure or an integrated hydraulic system; vibration and bumps during transport may cause deformation or damage to internal components, making separate transport impossible. Existing transportation methods present the following problems:

[0003] Fixed frame transportation: The telescopic arm is fixed to the transportation frame by welding or bolting. Custom-made tooling is required, and disassembly is complicated and has poor versatility.

[0004] Segmented transportation: The telescopic boom is disassembled into multiple segments for separate transportation, which requires frequent disassembly and reassembly of hydraulic pipelines and electrical wiring, posing a risk of secondary damage.

[0005] Simple support structure: temporary support made of wood or ordinary steel, which is not strong enough and can easily lead to deformation or surface wear of the telescopic arm.

[0006] One end of the telescopic boom has a mating part, and the other end is a hydraulic cylinder connection end. The end with the mating part is relatively rigid and is not easily damaged by repeated disassembly and assembly. Based on the common characteristics of telescopic booms, a highly versatile telescopic boom transport tool that can reduce disassembly damage is proposed. Utility Model Content

[0007] The purpose of this invention is to provide a telescopic boom transport fixture for a front-mounted crane, which solves the problems in the prior art, improves the structural strength and stability of the transport fixture, and optimizes the assembly and disassembly efficiency.

[0008] This utility model provides a telescopic boom transport fixture for a front-mounted crane, comprising:

[0009] A fixing mechanism for raising the mating part of the telescopic arm to a preset height includes a first support and a second support arranged in parallel, a connecting rod between the first support and the second support, and an mounting part provided on the first support for connecting with the mating part.

[0010] A guiding mechanism, one end of which is mounted on the carriage and the other end extends to the outside of the carriage; a fixing mechanism is detachably supported on the guiding mechanism and moves along a preset path with the guiding mechanism.

[0011] As described above, in a telescopic boom transport fixture for a front-end crane, preferably, the mounting component includes two mounting plates symmetrically arranged along the length direction of the first support. The mounting plates are provided with a first mounting hole and a plurality of second mounting holes. The plurality of second mounting holes are distributed in a ring at intervals around the outer periphery of the first mounting hole. Both the first mounting hole and the second mounting holes are engaged with the mating part.

[0012] In the telescopic boom transport fixture of the front-mounted crane described above, preferably, reinforcing ribs are provided on the opposing surfaces of the two mounting plates.

[0013] In the telescopic boom transport fixture of the front-end crane described above, preferably, the second support is symmetrically provided with support members connected to the first support on its side.

[0014] In the telescopic boom transport fixture of the front-end crane described above, preferably, guide plates are provided at both ends of the second support.

[0015] In the telescopic boom transport fixture of the front-end crane described above, preferably, the two sides of the guide plate are bent toward the second support to form a guide arc surface.

[0016] In the telescopic boom transport fixture described above, preferably, a shock-absorbing pad is provided on the contact surface of the telescopic boom facing the first support and the guide mechanism.

[0017] In the telescopic boom transport fixture of the front-end crane described above, preferably, the guiding mechanism includes two parallel guide rails.

[0018] In the telescopic boom transport fixture of the front-end crane described above, preferably, at least a portion of the guide rail is symmetrically fixed with limiting stops along its length.

[0019] Compared with the prior art, this utility model adopts a steel frame structure. One end of the telescopic arm is fixed to the fixed mechanism through the mounting component. The universal end of the fixed telescopic arm increases its versatility. One end of the guide mechanism extends to the outside of the carriage. After the telescopic arm is connected to the fixed mechanism, the fixed mechanism can be supported on the guide mechanism, and the other end of the telescopic arm is supported on the other end of the guide mechanism. The guide mechanism moves along a preset path, thereby driving the fixed mechanism and the telescopic arm to enter and exit the carriage. The telescopic arm does not need to be disassembled and can be put into the carriage as a whole, reducing disassembly and assembly damage. In addition, the fixed mechanism and the guide mechanism can limit the telescopic arm to prevent it from shaking in the carriage. Moreover, the contact area between the two and the telescopic arm is small, avoiding the wear caused by the disassembly and assembly of the existing support structure and the telescopic arm.

[0035] The embodiments described below with reference to the accompanying drawings are exemplary and are only used to explain the present invention, and should not be construed as limiting the present invention.

[0036] SeeFigure 4 As shown in Figure 6, the telescopic boom 50 of the front-end crane is relatively large, and is usually transported using methods such as segmented disassembly and assembly or fixed frame connection. Segmented disassembly and assembly may cause secondary damage to the telescopic boom 50, while fixed frame connection increases material consumption and lacks versatility. One end of the telescopic boom 50 has a mating part 51, and the other end is a hydraulic cylinder connection end. The end with the mating part 51 is relatively rigid and is not easily damaged by repeated disassembly and assembly. The mating part 51 has a detachable shaft pin 511. Therefore, this utility model provides a transport fixture for the telescopic boom 50 of the front-end crane, including a fixing mechanism 10 and a guiding mechanism 40, wherein:

[0037] See Figure 1 As shown, the fixing mechanism 10 includes a first support 11 and a second support 12 arranged in parallel. A connecting rod 13 is provided between the first support 11 and the second support 12. The fixing mechanism 10 is used to lift the mating part 51 of the telescopic arm 50 to a preset height. One end of the telescopic arm 50 with the mating part 51 is lower than the cylinder connection end of the telescopic arm 50. By setting the fixing mechanism 10 with a certain height, this end of the mating part 51 can be raised so that the two ends of the telescopic arm 50 reach the set relative height. The fixing mechanism 10 adopts a steel frame structure, which is welded from channel steel into an I-shaped structure to increase the support bending strength. An mounting part 20 is provided on the first support 11. The mounting part 20 is used to connect with the mating part 51.

[0038] See Figure 7 As shown in Figure 8, one end of the guide mechanism 40 is mounted on the carriage 60, and the other end of the guide mechanism 40 extends to the outside of the carriage 60. The guide mechanism 40 is not fixedly connected to the carriage 60, and is only partially placed inside the carriage 60. The part of the guide mechanism 40 extending to the outside of the carriage 60 is lifted by a forklift or other device and can serve as a moving track.

[0039] The fixing mechanism 10 is supported on the guide mechanism 40 and moves along a preset path with the guide mechanism 40. After fixing the mating part 51 to the mounting part 20, the fixing mechanism 10, together with the telescopic arm 50, is placed on the guide mechanism 40. The cylinder connection end of the telescopic arm 50 is positioned at the other end of the guide mechanism 40. The telescopic arm 50 and the guide mechanism 40 are fixed relative to each other. By pushing the guide mechanism 40 into the carriage 60, the telescopic arm 50 enters the carriage 60. The preset path is the path along which the guide mechanism moves into the carriage 60. The telescopic arm 50 does not need to be disassembled during transportation, achieving overall transportation. By selecting the telescopic arm 50 with the common feature of the mating part 51, it can fully cover mainstream port machinery models. For telescopic arms 50 with inconsistent dimensions at one end of the mating part 51, the dimensions of the fixing mechanism 10 can be changed to adapt them, thus making them suitable for a wider range of models.

[0040] In this embodiment, see Figure 1 -2 and Figure 4As shown, the mounting component 20 includes two mounting plates 21 symmetrically arranged along the length of the first support 11. Each mounting plate 21 has a first mounting hole 22 and several second mounting holes 23. The several second mounting holes 23 are annularly spaced around the outer periphery of the first mounting hole 22. Both the first mounting hole 22 and the second mounting hole 23 engage with the mating part 51. First, the pin 511 is removed from the mating part 51. The end of the telescopic arm 50 with the mating part 51 is placed between the two mounting plates 21. Then, the pin 511 is passed through the first mounting hole 22, and bolts are used to fix the second mounting hole 23, the mating part 51, and the pin 511. The mounting component 20 can connect the telescopic arm 50 to the fixing mechanism 10. The pin 511 integrated into the mating part 51 can also be used for positioning, and the pin 511 does not need to be disassembled, preventing part loss.

[0041] See Figure 1 -2 and Figure 4 As shown, reinforcing ribs 24 are provided on the opposing surfaces of the two mounting plates 21. The reinforcing ribs 24 are used to reinforce and fix the mounting plates 21, thereby increasing the overall rigidity and strength of the mounting plates 21 and improving their resistance to deformation.

[0042] See Figure 1 , 3 As shown, to increase the stability of the fixing mechanism 10, the second support 12 is symmetrically provided with support members 14 connected to the first support 11 on its side. The support member 14 includes a base plate 141 and an inclined plate 142. The base plate 141 is located on the side of the second support 12, one end of the inclined plate 142 is connected to the base plate 141, and the other end of the inclined plate 142 is connected to the first support 11. The support member 14 and the fixing mechanism 10 form a triangular structure, which increases the strength and stability of the fixing mechanism 10. The lower surfaces of the base plate 141 and the second support 12 are located on the same horizontal plane. The first support 11, the second support 12, and the support member 14 all adopt channel steel structure, which ensures the support strength while enhancing the load-bearing capacity of the structure in the horizontal and vertical directions.

[0043] Because the telescopic boom 50 is quite long, the guide mechanism 40 is pushed into the carriage 60 by a forklift to move it along a preset path. Slight deviation may occur during this movement. (See attached image.) Figure 1 , 3 As shown, guide plates 15 are provided on both sides of the second support 12. The guide plates 15 can correct the offset in time, ensuring that the telescopic boom 50 accurately enters the designated position inside the carriage 60, thus improving the accuracy and reliability of the operation.

[0044] See Figure 3As shown, the two sides of the guide plate 15 are bent towards the second support 12 to form a guide arc surface 151. The guide arc surface 151 can guide the guide mechanism 40 back to the correct direction when it deviates slightly. The arc surface design can reduce the frictional resistance between the guide plate 15 and the carriage 60. The guide arc surface 151 on both sides can play a guiding role when the telescopic arm 50 enters and exits the carriage 60.

[0045] In this embodiment, see Figure 4 As shown in Figure 6, a shock-absorbing pad 30 is provided on the contact surface of the telescopic arm 50 facing the first support 11 and the guide mechanism 40. The shock-absorbing pad 30 is made of an elastic material, such as polyurethane, or other pads with shock-absorbing effects, which is not limited here. The shock-absorbing pad 30 can reduce damage to the telescopic arm 50 and suppress the transmission of vibration during transportation. The shock-absorbing pad 30 can be set on multiple contact surfaces of the telescopic arm 50 to form a multi-point distributed fixation. Of course, in another embodiment, the shock-absorbing pad 30 can also be set at the corresponding position of the first support 11 or the guide rail 41, which is not limited here.

[0046] In this embodiment, see Figure 6 As shown in Figure 8, the guiding mechanism 40 includes two parallel guide rails 41. The two guide rails 41 are placed inside the carriage 60 at a certain distance. The guide rails 41 can be C-shaped channel steel structures, with the opening of the channel steel facing the carriage 60, which facilitates the subsequent removal of the guide rails 41 from the carriage 60. The fixing mechanism 10 is placed on the upper surface of the channel steel, and the opening of the channel steel of the second support 12 faces upward. The lower surface of the second support 12 is in contact with the upper surface of the guide rail 41, which facilitates the movement of the fixing mechanism 10 on the guide rails 41 when the position of the fixing mechanism 10 needs to be adjusted.

[0047] See Figure 6 As shown, at least a portion of the guide rail 41 is symmetrically fixed with limiting bars 42 along its length. The limiting bars 42 are located near the cylinder connection end. When the fixing mechanism 10 is placed on the guide rail 41, the cylinder connection end falls between the two limiting bars 42. The cylinder connection end is relatively weak, and the limiting bars 42 can limit and protect this end, and can fix the telescopic arm 50 relatively to the guide rail 41. During transportation, it plays a certain supporting and fixing role, preventing the telescopic arm 50 from moving. In addition, the contact surface between the telescopic arm 50 and the fixing mechanism 10 and the guide rail 41 is small. After the telescopic arm 50 enters the carriage 60, it can be reinforced by the existing reinforcement structure, without the need for customized special tooling for welding or bolt fixing, thus reducing the damage caused by disassembling or fixing the telescopic arm 50.

[0048] Based on the above embodiments, the usage process of this utility model is as follows:

[0049] Two guide rails 41 are placed inside the carriage 60 at a certain distance. The part of the guide rails 41 extending outside the carriage 60 is lifted by a forklift. The axle pin 511 of the mating part 51 is removed. The mating part 51 is placed between two mounting plates 21. The axle pin 511 passes through the mating part 51 and the first mounting hole 22. The mating part 51 is fixed to the mounting plate 21 by bolts and the second mounting hole 23. The fixed telescopic arm 50 and the fixing mechanism 10 are placed on the guide rails 41 by a lifting device. The hydraulic cylinder connection end is placed between two limit bars 42. The two guide rails 41 are pushed into the carriage 60 by a forklift, thereby sending the telescopic arm 50 into the carriage 60. Using this application can shorten the disassembly and assembly time by more than 50%, achieve a tooling reuse rate of 95%, increase container space utilization by 30%, reduce single transportation costs by 25%, and provide a support structure with a bending strength of ≥500MPa. It can withstand the turbulence of sea transport and the impact of hoisting, and has high reliability and flexible adaptability. By selecting the common features of the front crane telescopic boom 50 mating part 51, it can fully cover mainstream port machinery models.

[0050] The above description, based on the embodiments shown in the drawings, details the structure, features, and effects of this utility model. The above description is only a preferred embodiment of this utility model, but the scope of implementation of this utility model is not limited to what is shown in the drawings. Any changes made in accordance with the concept of this utility model, or modifications to equivalent embodiments, that do not exceed the spirit covered by the specification and drawings, shall be within the protection scope of this utility model.
