Description

Technical Field

[0001] The invention belongs to the technical field of electrical installation, and relates to a large spare parts transportation method used in a complex space in an electrical room. Background Art

[0002] In modern industrial production, crane equipment, as an important lifting and transportation tool, is widely used in various production scenarios. The normal operation of its electrical room is crucial to ensure the stability and safety of the crane equipment. However, the crane electrical room usually has the characteristics of small space and complex internal structure, which puts high demands on the replacement and maintenance of its internal spare parts. Especially when large spare parts need to be replaced, due to the large size and heavy weight of spare parts, traditional transportation and installation methods are often difficult to adapt to complex spatial environments, resulting in low replacement efficiency, and may even affect production progress due to the inability to replace spare parts in time.

[0003] In the prior art, some relatively conventional methods are usually used for the transportation and installation of spare parts in the electrical room. For example, the spare parts are hoisted into the electrical room by an electric hoist, and then the spare parts are slid on the ground to the installation position using the rollers equipped on the spare parts themselves, or the spare parts are moved to the designated location by manual handling by construction workers. These methods can meet the needs in some cases, especially when the electrical room is relatively open, the ground is flat, and the spare parts are small in size and weight. However, with the large-scale and complex industrial equipment, the structural design and spare parts specifications of the crane electrical room are also constantly upgraded, which makes the limitations of traditional methods increasingly prominent.

[0004] Taking a specific case in actual production as an example, the main hook spare part that needs to be replaced in a certain crane electrical room weighs more than 300 kilograms and is large in size. However, the space inside the electrical room is narrow, there are raised structures on the ground, and the spare part itself is not equipped with rollers, so it cannot be transported by sliding on the ground. In addition, due to space limitations, the electrical room cannot accommodate too many construction workers, and manual transportation is not feasible due to the dual constraints of weight and space. In this case, the traditional experience of lifting by electric hoists and manual transportation is no longer applicable. Not only that, if the replacement of spare parts is not completed in time, the continued damage to the crane equipment may cause the production line to stagnate, causing significant economic losses to the company. Therefore, in order to solve the problem of large spare parts transportation in the complex space of the electrical room, there is an urgent need for a solution that can adapt to narrow spaces and complex structures and is easy to operate and labor-saving.

[0005] From a broader technical background, there are also some improved solutions in the existing technology for handling objects in narrow spaces. For example, in some industrial scenarios, small rail cars or pulley systems are used to move heavy objects on the ground, but these methods usually require the ground to be flat and free of obstacles, which obviously cannot adapt to the raised ground in the electrical room. In addition, there are some technologies that achieve the handling of heavy objects by adding robotic arms or automated equipment, but such equipment is often expensive and difficult to arrange and operate in small spaces such as electrical rooms. Other methods try to assist in handling by temporarily building simple support structures, but these structures are not stable enough, and the construction and disassembly process takes a long time, which cannot meet the needs of rapid replacement of spare parts.

[0006] In summary, the existing technologies generally have the following deficiencies when dealing with the problem of transporting large spare parts in complex spaces in electrical rooms: First, there is a lack of special transport means for narrow spaces and complex structures, resulting in low transport efficiency; second, traditional methods are highly dependent on the conditions of the spare parts themselves (such as whether they are equipped with rollers) and have poor adaptability; third, manual handling is limited by space and weight, making it difficult to achieve safe and efficient operation; fourth, although some improvement plans have certain effects, they are not universal due to high costs or complex operations. Therefore, how to achieve labor-saving, fast and successful transport and replacement of large spare parts in an environment with small spaces and complex structures such as electrical rooms has become a technical problem that technicians in this field need to solve urgently. In response to the above problems, developing a transport method that is simple to operate, highly adaptable and cost-controlled can not only improve the efficiency of spare parts replacement in electrical rooms, but also effectively reduce production risks caused by equipment failures, which has important practical value and economic significance. Summary of the invention

[0007] In view of this, in view of the above problems existing in the prior art, the purpose of the present invention is to provide a method for transporting large spare parts in complex spaces in electrical rooms, so as to solve the problems of low transport efficiency and difficult operation in narrow spaces and complex structures in traditional methods. Through the innovative design of the transport structure, the present invention can realize the labor-saving, fast and successful transport and replacement of large spare parts in environments with limited space and poor ground conditions such as the electrical room of a traveling crane, thereby avoiding the risk of affecting production due to the inability to repair equipment in time due to damage.

[0008] In order to achieve the above object, the present invention provides the following technical solutions:

[0009] A method for transferring large spare parts in a complex space in an electrical room comprises the following steps:

[0010] 1) Fix two I-beams on the top of the electrical room by welding to form a track for the movement of spare parts;

[0011] 2) The spare parts to be transported are fixed under two cable pulleys, each of which is placed on the two I-beam rails;

[0012] 3) The cable trolley moves on the track to drive the spare parts to be transported along the track to the corresponding installation position;

[0013] 4) After the spare parts are transported to the installation location, weld the lifting lugs on the I-beam rails at the installation location and install the hand chain hoist on the lifting lugs;

[0014] 5) By operating the hand hoist, the spare parts are gradually moved and placed on the installation feet to complete the replacement of the spare parts.

[0015] Furthermore, the spacing between the two I-beams is determined according to the width of the spare parts to be transported, and the length of the I-beam covers the distance from the spare parts entry position to the installation position in the electrical room to ensure the stability of the spare parts during transportation. The cable pulley is fixed to the spare parts by a rope or wire rope with adjustable length. The length of the rope or wire rope is adjusted according to the height of the electrical room and the distance between the bottom of the spare parts and the ground to avoid collision between the spare parts and the raised structure on the ground during transportation. The number of lifting ears is at least two, which are welded to the corresponding positions of the I-beam track respectively, and the rated load of the hand winch is greater than 1.5 times the weight of the spare parts to be transported to ensure safety and stability during lifting and lowering. In addition, the movement of the cable pulley can be achieved by manual pushing or installing an auxiliary traction device, which includes but is not limited to an electric winch or a pull rope system to further improve the transportation efficiency and operational convenience.

[0016] The present invention achieves convenient transportation and precise installation of large spare parts in a narrow space by setting a track system composed of two I-beams on the top of the electrical room, combined with the use of cable pulleys and hand winches. With this method, spare parts can be moved along the top track through cable pulleys, effectively avoiding obstacles such as ground protrusions, and solving the limitations of traditional ground sliding or manual handling methods. When the spare parts arrive at the installation location, the introduction of hand winches further simplifies the vertical positioning and installation process of the spare parts, ensuring labor-saving and efficient operation.

[0017] The beneficial effects of the present invention are:

[0018] 1. The top rail and cable pulley design avoids the limitation of ground conditions and is suitable for electrical room environments with uneven ground or raised structures;

[0019] 2. The operation process does not require a large number of construction workers, adapts to the operation requirements of narrow spaces, and reduces dependence on manpower;

[0020] 3. Combined with adjustable ropes and hand hoists, it ensures accurate positioning and rapid replacement of spare parts in complex spaces;

[0021] 4. Provides two moving modes: manual and auxiliary traction, which enhances the flexibility and practicality of the method;

[0022] 5. The overall solution has a simple structure, controllable costs, and strong promotion value.

[0023] Other advantages, objectives and features of the present invention will be described in the following description to some extent, and to some extent, will be obvious to those skilled in the art based on the following examination and study, or can be taught from the practice of the present invention. The objectives and other advantages of the present invention can be realized and obtained through the following description. BRIEF DESCRIPTION OF THE DRAWINGS

[0032] See also Figures 1 to 3 , which is a method for transporting large spare parts in complex spaces in electrical rooms, comprising the following steps:

[0033] 1) Fix two I-beams on the top of the electrical room by welding to form a track for the spare parts to move;

[0034] 2) The spare parts to be transported are fixed under two cable pulleys, each of which is placed on the two I-beam rails;

[0035] 3) The cable trolley moves on the track to drive the spare parts to be transported along the track to the corresponding installation position;

[0036] 4) After the spare parts are transported to the installation location, weld the lifting lugs on the I-beam rails to be installed, and install the hand chain hoists on the lifting lugs;

[0037] 5) By operating the hand hoist, the spare parts are gradually moved and placed on the installation feet to complete the replacement of the spare parts.

[0038] In a spare parts replacement task in a certain vehicle electrical room, a large spare part 4 needs to be transported and installed. The large spare part 4 weighs about 320 kilograms and is 1.2 meters wide. The space inside the electrical room is small, and there is a raised structure 5 on the ground with a height of about 0.4 meters. Traditional ground sliding or manual transportation methods are not applicable. Using the method of the present invention, firstly, two I-beams 3 are installed as tracks on the top of the electrical room through welding fixing points 2. The track spacing is adjusted to 1.5 meters according to the width of the large spare part 4. The length of the I-beam 3 is 5 meters, covering the distance from the spare part entry position to the installation position to ensure the stability of transportation (see Figure 1 and Figure 2 ).

[0039] Then, the large spare part 4 is fixed to the bottom of two cable pulleys 1 by adjustable length steel wire ropes. Each cable pulley 1 is installed on two I-beam 3 rails. The length of the steel wire rope is adjusted to 1.2 meters, so that the bottom of the large spare part 4 is kept 0.3 meters away from the floor protrusion 5 of the electrical room to avoid collision during transportation. By manually pushing the cable pulley 1, the large spare part 4 moves smoothly along the I-beam 3 rail to the top of the installation position. The whole moving process is as follows: Figure 3 Step 3 in the process shown.

[0040] When the large spare part 4 arrives at the installation location, two lifting lugs are installed at the corresponding positions on the I-beam 3 rail by welding the fixing points 2, and a hand chain hoist with a rated load of 500 kg is mounted on the lifting lugs. The hand chain hoist is operated to slowly lower the large spare part 4 to the installation foot, adjust the position and fix it, and finally complete the replacement. The whole process only requires 2 construction workers and takes about 1 hour. The operation is labor-saving and efficient, avoiding the interference of the ground protrusion 5 on the transportation.

[0041] As an improved embodiment, if the transportation distance is long or the weight of the spare parts increases, an electric winch can be installed on the cable pulley 1 as an auxiliary traction device to achieve the movement of the large spare parts 4 through remote control operation, thereby further improving efficiency. Figure 1 and Figure 2 The matching structure of the cable pulley 1 and the I-beam 3 shown in the figure can flexibly adapt to different spare parts sizes and electrical room environments to ensure the stability and safety of transportation.

[0042] Finally, it should be noted that the above embodiments are only used to illustrate the technical solution of the present invention rather than to limit it. Although the present invention has been described in detail with reference to the preferred embodiments, those skilled in the art should understand that the technical solution of the present invention can be modified or replaced by equivalents without departing from the purpose and scope of the technical solution, which should be included in the scope of the claims of the present invention.
