Description

Technical Field

[0001] The utility model relates to the field of crane production equipment, in particular to an assembled walking mechanism protection device for crane production. Background Art

[0002] During the general assembly stage of port cranes, the walking mechanism is at the bottom of the whole machine. Due to a large amount of subsequent general assembly work and a long duration, dust, welding slag, paint, etc. are easily dropped onto the walking mechanism. After the general assembly is completed, the appearance of the walking mechanism is poor. Moreover, after the dust, welding slag, paint, etc. that fall on the walking mechanism adhere to the walking wheels, it will affect the stability of the walking wheels and the track during the combined movement. By shielding and protecting the walking mechanism during the general assembly operation, the shielding objects are often damaged by the strong wind by the sea, resulting in poor durability. At the same time, due to the poor weather resistance of the shielding objects, short-term damage is likely to occur.

[0003] A protective cover for the walking mechanism of a circular yard stacker-reclaimer is disclosed in a Chinese patent (Publication No.: CN 213201536 U), which includes a housing, wheels and a cover shell. One end of the housing is evenly and rotatably connected with wheels, and a cover shell is arranged outside the wheels. One side inside the cover shell is hinged with a first baffle door, and the other side inside the cover shell is hinged with a second baffle door. A clamping plate is welded at the middle position of one end of the first baffle door close to the second baffle door; when the stone particles at a high place fall, they will first fall on the baffle plate, and the buffer spring will buffer, reducing part of the impact force. It is a protective cover fixed to the walking mechanism, which moves and adjusts following a single walking mechanism, and is not convenient for disassembly, transfer and reuse. It is applicable to the use scenario during the long-term service of the crane. For the production stage of the crane, this kind of protective cover can only protect a single crane walking mechanism. Installing a permanent protective cover on each crane during continuous production will lead to an increase in production costs and production processes, and is not applicable to the use during crane production.

By disassembling and assembling some flexible cables, rapid disassembly, transfer and assembly use are realized, and the applicability is improved.

[0005] In order to achieve the above purpose, the following technical solutions are adopted:

[0006] An assembled walking mechanism protection device for crane production, comprising a protective cover. The protective cover is in the shape of a housing with an open bottom, and a through hole for the leg to pass through is provided at the top of the protective cover. In the moving direction of the walking mechanism, the protective cover is divided into two identical parts. Each part includes an end cloth and side cloths. The side cloths are respectively connected to both sides of the end cloth, and the end cloth extends from the top of the protective cover to the end of the protective cover.

[0027] In a typical embodiment of the present utility model, as Figures 1-4 shown, an assembled walking mechanism protection device for crane production is proposed.

[0028] Currently, the protection structure adopted by the walking mechanism 7 of port cranes is a structure fixed to the crane, which is inconvenient to be transferred between multiple cranes and is only applicable when the crane works at the port for a long time and is not applicable to the crane production scenario. Based on this, this embodiment provides an assembled walking mechanism protection device for crane production, which uses multiple flexible cloths spliced to form a shell-shaped protective cover 8, which can be disassembled and combined, so as to be easily applicable to different cranes for transfer.

[0029] As Figure 1 shown, the main structure of the assembled walking mechanism protection device for crane production is the protective cover 8. The protective cover 8 is in the shape of a shell with an open bottom, which is convenient to cover the walking mechanism 7 and leave necessary operating space. In order to facilitate disassembly, transfer and recombination for use, the protective cover 8 can be divided into two identical parts in the moving direction of the walking mechanism 7. Each part consists of an end cloth 1 and side cloths. The two parts respectively form a partial shell-shaped structure, so that the entire assembled walking mechanism protection device for crane production can be combined by splicing at the disassembly position, so as to form a complete coverage of the walking mechanism 7, and at the same time, it is also convenient for disassembly, installation and transportation.

[0030] Specifically, in order to facilitate the connection of the two parts of the protective cover 8, holes 9 can be provided at the edges of the splicing positions of the two parts of the protective cover 8, and flexible cables can be passed through the holes 9 at the edges to splice the two parts of the protective cover 8, ensuring the flexibility of the structure. A through hole for the support leg to pass through is reserved at the top of the protective cover 8 to ensure the normal use of the support leg during crane operation is not affected.

[0031] The disassembly and assembly of the traditional protection device are complex, time-consuming and laborious, affecting production efficiency. In this embodiment, by disassembling and assembling some flexible cables, the rapid disassembly and reassembly of the protective cover 8 can be realized, greatly improving the flexibility and applicability of the device.

[0032] As Figure 2 shown, each part of the protective cover 8 respectively includes an end cloth 1 and side cloths. The side cloths are respectively connected to both sides of the end cloth 1. The end cloth 1 extends from the top of the protective cover 8 to the end of the protective cover 8 to shield the top and one end; the end cloths 1 of the two parts are connected at the top of the protective cover 8 to make the top of the protective cover 8 fit together, and the side parts of the two parts are connected at the side of the protective cover 8 to make the side of the protective cover 8 fit together.

[0033] It should be noted that taking the Figure 3 posture as an example, the walking mechanism 7 moves in the left-right direction, and the end of the protective cover 8 is determined along the moving direction of the walking mechanism 7.Figure 3 The side of the protective cover 8 facing the direction shown is the side surface of the protective cover 8. It can be seen that the side surface of the protective cover 8 is approximately trapezoidal, as Figure 4 shown, the end face of the protective cover 8 is approximately rectangular.

[0034] The bottom opening design of the protective cover 8 allows the crane traveling mechanism 7 to cooperate with the bottom track. At the same time, the top and side surfaces form a closed protective structure, effectively preventing external pollutants from entering and reducing the adhesion of dust, welding slag, paint, etc. to the traveling mechanism 7 during final assembly. The protective cover 8 is divided into two symmetrical parts, and each part includes a piece of end cloth 1 and two side cloths. The end cloth 1 mainly covers the top and front and rear ends of the traveling mechanism 7, while the side cloths cover both sides of the traveling mechanism 7, simplifying the installation and disassembly process and ensuring comprehensive protection.

[0035] Flexible cables are usually made of high-strength, wear-resistant, and corrosion-resistant materials such as nylon ropes and polyester fiber ropes. They have good flexibility and tensile strength and can withstand the tension and deformation between the protective cloths. Uniformly distributed holes 9 are provided at the edges of the protective cloths, and the flexible cables are passed through the holes 9 and fixed by special buckles or knots. This connection method allows the flexible cables to be easily untied or retied when needed, thus enabling the quick disassembly and assembly of the protective cover 8.

[0036] The position and size of the through holes at the top of the protective cover 8 are precisely designed according to the actual dimensions and layout of the crane outriggers to ensure that the outriggers will not interfere with the protective cover 8 during the telescoping and rotating processes. Reinforcing materials or wear-resistant pads may also be provided at the edges of the through holes to prevent friction and wear between the outriggers and the protective cover 8.

[0037] For easy disassembly and assembly, each module of the protective cover 8 is marked and numbered to facilitate identification and positioning during the disassembly and assembly processes. This helps to reduce confusion and errors and improve the disassembly and assembly efficiency. The modular design, flexible end cloth 1, and side cloths enable the protective device to be easily loaded into a transportation tool after disassembly, reducing the requirements for transportation space and logistics costs. At the same time, the disassembled modules are also easier to store and manage, reducing the difficulty and cost of warehouse management.

[0038] As Figure 1 and Figure 3 shown, the side cloth is trapezoidal. In the moving direction of the traveling mechanism 7, the side cloth includes a terminal side cloth, a central side cloth, and a splicing cloth 6 connected in sequence. The splicing cloth 6 corresponding to one part of the protective cover 8 is connected to the central side cloth corresponding to the other part of the protective cover 8. The side cloth is composed of three sections: the terminal side cloth, the central side cloth, and the splicing cloth 6, which can better fit the side profile of the crane traveling mechanism 7, especially when the side surface of the traveling mechanism 7 is not a straight line but has a certain curvature. The splicing cloth 6 enables the two parts of the protective cover 8 to be closely connected on the side, reducing the gap between the protective cover 8 and the traveling mechanism 7 and enhancing the protective effect.

[0039] As Figure 2 shown, the end-side cloth includes a first end-side cloth 2 and a second end-side cloth 3, both of which are triangular and symmetrically distributed with respect to the connection line of the two parts of the protective cover 8. The structures of the first end-side cloth 2 and the second end-side cloth 3 are adapted to the shape of the side surface of the end of the traveling mechanism 7, making the protective cover 8 more neat and beautiful in appearance, and also facilitating alignment and positioning during installation and disassembly.

[0040] The center-side cloth includes a first center-side cloth 4 and a second center-side cloth 5, which are symmetrically distributed with respect to the connection line of the two parts of the protective cover 8. Similar to the end-side cloth, the center-side cloth can be adaptively cut according to the side shape of the traveling mechanism 7 to obtain a matching shape, improving the shielding and protection effect.

[0041] The splicing cloth 6 of one part of the protective cover 8 is connected to the side surface of the corresponding end face cloth 1 of the other part of the protective cover 8; the splicing cloth 6 is not only connected to the end face cloth 1 of the same part, but also connected to the side surface of the end face cloth 1 of the other part, forming an integral protective structure. This enhances the integrity and stability of the protective cover 8 and prevents the failure of protection caused by weak local connection.

[0042] Both sides of the end face cloth 1 extend to the side surface of the protective cover 8, and the edge of the end face cloth 1 is connected to the side cloth at the connection side of the side surface of the protective cover 8. Considering the connection requirements with the side cloth, both sides of the end face cloth 1 extend to the side surface of the protective cover 8 and are connected to the side cloth. This ensures a tight connection between the end face cloth 1 and the side cloth, prevents the appearance of gaps on the side surface of the protective cover 8, and improves the sealing performance and protection effect of the protective cover 8.

[0043] Holes 9 are respectively provided at the edges of the end face cloth 1 and the side cloth. The end face cloth 1 and the side cloth are spliced by passing a flexible cable through the holes 9. Establishing the connection between the end face cloth 1 and the side cloth with a flexible cable can facilitate the disassembly, installation and transportation of the protective cover 8, improve the disassembly and installation efficiency, and reduce the transportation cost. It can be understood that holes 9 are also provided at the edges of the first end-side cloth 2, the second end-side cloth 3, the first center-side cloth 4, the second center-side cloth 5, and the splicing cloth 6. Passing a flexible cable through the holes 9 can establish connections with other adjacent flexible cloths.

[0044] Rigid buckles are installed on the holes 9, and the flexible cable passes through the rigid buckles. This enhances the connection strength between the flexible cable and the holes 9 and prevents the flexible cable from falling off during use.

[0045] One end of the end face cloth 1 is provided with a slot. After the end face cloths 1 of the two parts of the protective cover 8 are connected, the corresponding slots are spliced to form a through hole for the leg of the crane to pass through.

[0046] The knife-coated fabric is selected as the material for the end face fabric 1 and the side fabric. The knife-coated fabric has characteristics such as high strength, wear resistance, and anti-aging, and is suitable for making the protective cover 8. The durability and service life of the protective cover 8 are improved.

[0047] The above are only the preferred embodiments of the present invention and are not intended to limit the present invention. For those skilled in the art, the present invention can have various changes and modifications. Any modifications, equivalent replacements, improvements, etc. made within the spirit and principle of the present invention shall be included within the protection scope of the present invention.
