Description

Technical Field

[0001] This utility model belongs to the field of generator room technology, specifically relating to a foldable cable tray for a mobile diesel generator room. Background Technology

[0002] In the power supply sector, mobile diesel generator rooms serve as crucial equipment for emergency power supply, field operations, and large-scale engineering construction, playing a vital role in ensuring continuous power output. With the increasing demand for power capacity from industrial production and infrastructure construction, the output power of mobile diesel generator rooms has been continuously increasing. Currently, the output power of mainstream equipment is generally stable in the range of 500–1200 kW, which can meet the power supply needs of high-load power consumption scenarios. To further enhance power supply capacity to adapt to larger-scale power consumption scenarios, multiple mobile diesel generator rooms are often operated in parallel in practical applications. Due to the large output power of a single generator room, and the need for power aggregation and transmission via cables after parallel operation, the diameter of the cables connecting the generator room and external power equipment increases significantly, resulting in a substantial increase in the overall weight of the cables. This places higher demands on the load-bearing capacity of the cable trays used to support and fix the cables. These trays must not only possess sufficient structural strength to withstand the weight of the thick cables but also ensure stability and reliability during long-term use, preventing cable displacement or damage due to insufficient tray load-bearing capacity, thereby affecting the safety of power transmission.

[0003] In existing technologies, the output cable trays of mobile diesel generator rooms generally adopt a fixed structure design that is directly welded to the end of the generator room. Although this design can meet the basic requirements for cable support, it has obvious defects in the equipment transportation process: on the one hand, the welded fixed trays will extend outwards, occupying additional transportation space, which will significantly reduce the loading efficiency of the transportation vehicle, increase transportation costs, and waste transportation resources; on the other hand, after the cable trays of some generator room models are welded, the overall equipment length exceeds the standard length limit of conventional transportation vehicles, requiring special transportation methods or additional disassembly, which increases the difficulty and cost of transportation. Therefore, it is necessary to improve the design to address the above problems. Utility Model Content

[0004] The technical problem solved by this utility model is to provide a foldable cable tray for mobile diesel generator rooms. By hinged to the frame at the electrical control end of the mobile diesel generator room and setting hinged support components to support or lock the frame when unfolded or folded, the tray achieves stable support in use and space compression in transportation. This solves the problems of large transportation space occupation, low loading efficiency, high transportation cost and length exceeding limits that exist in fixed welded cable trays used in mobile diesel generator rooms. The foldable design structure takes into account both cable support reliability and transportation convenience. It does not require special transportation methods or additional disassembly, reduces transportation difficulty, improves the loading efficiency of transportation vehicles, and reduces transportation costs.

[0005] The technical solution adopted by this utility model is as follows: a foldable cable tray for a mobile diesel generator room, including a frame. The frame is located at the electrical control end of the mobile diesel generator room, and the inner side of the frame is hinged to the electrical control end of the mobile diesel generator room. A hinge support is installed below the hinge position between the mobile diesel generator room and the frame. When the frame is unfolded for use, the support part of the hinge support is detachably connected to the bottom of the frame. When the frame is in the transportation state, the frame is deconnected from the support part of the hinge support and rotated to connect with the locking part of the hinge support, thereby realizing the folding of the frame.

[0006] Among them, the frame is fixed with a support lug 1 on both ends of the bottom surface of the long side facing the mobile diesel generator room. The corner column corresponding to the position of the electrical control terminal of the mobile diesel generator room is fixed with a double lug seat 1 corresponding to the position of the support lug 1. The double lug seat 1 and the support lug 1 with the lug plate inserted in the double lug seat 1 are hinged by a pin.

[0007] Furthermore, the hinged support includes a slotted double-ear seat and a diagonal tie rod. The slotted double-ear seat is fixed to a corner post at the corresponding position of the electrical control terminal of the mobile diesel generator room. One end of the diagonal tie rod is fixed with a single-ear seat, and the other end of the diagonal tie rod is fixed with a double-ear seat. The ear plate of the single-ear seat is inserted into the double-ear plate at the lower end of the slotted double-ear seat, and the double-ear plate at the lower end of the slotted double-ear seat and the ear plate of the single-ear seat are hinged by a pin. When the frame is unfolded and in use, it is fixed to the frame... The second support lug on the bottom surface of the support end is connected to the second double lug seat by a pin, so that the diagonal tie rod supports the unfolded frame. When the frame is transported, the pin is pulled out to release the hinge state between the second support lug and the second double lug seat, and the frame is rotated so that the second support lug is connected to the double lug plate at the upper end of the slotted double lug seat by a pin, so as to lock the frame in the transport state. When the second support lug is connected to the double lug plate at the upper end of the slotted double lug seat, the downward-facing diagonal tie rod is rotated to position the mobile diesel generator room electrical control terminal.

[0008] Furthermore, the single ear seat has a T-shaped plate structure with the large end fixed to the end of the diagonal tie rod and the small end being semi-circular. When the second support ear is connected to the double ear plate at the upper end of the slotted double ear seat, the lower end of the diagonal tie rod abuts against the corner column of the electrical control terminal of the mobile diesel generator room, and the inner side wall of the lower end of the frame abuts against the large end boss of the single ear seat, thereby realizing the swing positioning of the diagonal tie rod.

[0009] Furthermore, the frame includes a bottom frame and a side frame with a length not greater than the width of the mobile diesel generator room. The bottom frame is a frame composed of multiple longitudinal bars and horizontal bars evenly distributed between adjacent longitudinal bars. The side frame is a frame composed of a longitudinal beam and multiple pillars evenly distributed on the bottom surface of the longitudinal beam. The lower ends of the pillars in the side frame are welded and fixed to the outer edge of the upper surface of the bottom frame.

[0010] Advantages of this utility model compared to the prior art: 1. This technical solution adopts a detachable and foldable connection structure between the hinged support and the frame hinged to the electrical control end of the mobile diesel generator room. In the transportation state, the frame can be folded close to the outer wall of the mobile diesel generator room, which greatly reduces the outward extension of the bracket, avoids occupying extra transportation space, improves the loading efficiency of the transportation vehicle, and reduces transportation costs. 2. The overall length of the folded equipment can be controlled within the length limit of conventional transportation vehicles, eliminating the need for special transportation methods or additional disassembly, thus reducing transportation difficulty; 3. When the frame of this technical solution is unfolded and used, it is connected to the frame by diagonal bracing rods through a detachable hinge to form a stable triangular support structure. Combined with the frame design of the frame itself, which is composed of longitudinal bars, transverse bars and support columns, it can effectively bear the load of large-diameter and heavy cables, avoid cable displacement or damage, and ensure the safety of power transmission. 4. The connection between the frame and the hinged support in this technical solution is achieved by a pin. The opening and closing can be switched by inserting and removing the pin. The operation is simple and does not require complicated tools, making it easy to operate quickly on site. 5. Under the premise that the upper end of the slotted double-ear seat is connected to the second support ear, this technical solution adopts a T-shaped plate-like single-ear seat that abuts against the corner column of the mobile diesel generator room's electrical control end and the frame, which can double limit the diagonal tie rod to avoid shaking during transportation and ensure structural stability; no additional complex locking parts are required, simplifying the design, reducing wear and maintenance costs, and improving the convenience and safety of folding transportation.

[0015] Foldable cable trays for mobile diesel generator rooms, such as Figure 1-5As shown, the device includes a frame 1, which is located at the electrical control terminal of a mobile diesel generator room 2. The inner side of the frame 1 is hinged to the electrical control terminal of the mobile diesel generator room 2. A hinge support is installed below the hinge position between the mobile diesel generator room 2 and the frame 1. When the frame 1 is unfolded for use, the support part of the hinge support (i.e., the double ear seat 9 at the end of the diagonal tie rod 6) is detachably connected to the bottom of the frame 1. When the frame 1 is in the transport state, the frame 1 is disconnected from the support part of the hinge support and rotated to connect with the locking part of the hinge support (i.e., the double ear plate at the upper end of the slotted double ear seat 5), thereby realizing the folding of the frame 1. In the above structure, by hinged frame 1 at the electrical control end of the mobile diesel generator room 2 and setting hinged support components to support or lock frame 1 when unfolded or folded, the stable support of the bracket in the use state and the space compression in the transportation state are realized. This solves the problems of large transportation space occupation, low loading efficiency, high transportation cost and length exceeding limit that exist in the mobile diesel generator room 2 using fixed welded cable brackets. The foldable design structure takes into account the reliability of cable support and the convenience of transportation. It does not require special transportation methods or additional disassembly, reduces transportation difficulty, improves the loading efficiency of transportation vehicles, and reduces transportation costs.

[0016] The hinge structure of the frame 1 at the electrical control end of the mobile diesel generator room 2 is as follows: The frame 1 has a support lug 3 fixed on the bottom surface of both ends of the long side facing the mobile diesel generator room 2. The corner post at the corresponding position of the electrical control end of the mobile diesel generator room 2 has a double lug seat 4 corresponding to the position of the support lug 3. The double lug seat 4 and the support lug 3, which is inserted into the lug seat 4, are hinged by a pin.

[0017] The specific structure of the frame 1 is as follows: The frame 1 includes a bottom frame 1-1 and a side frame 1-2 with a length not greater than the width of the mobile diesel generator room 2. The bottom frame 1-1 is a frame composed of multiple longitudinal bars and horizontal bars evenly distributed between adjacent longitudinal bars. The side frame 1-2 is a frame composed of a longitudinal beam and multiple pillars evenly distributed on the bottom surface of the longitudinal beam. The lower ends of the pillars in the side frame 1-2 are welded and fixed to the outer edge of the upper surface of the bottom frame 1-1.

[0018] The specific structure of the hinged support is as follows: The hinged support includes a slotted double-ear seat 5 and a diagonal tie rod 6. The slotted double-ear seat 5 is fixed to the corner post at the corresponding position of the electrical control terminal of the mobile diesel generator room 2. One end of the diagonal tie rod 6 is fixed with a single-ear seat 8, and the other end of the diagonal tie rod 6 is fixed with a double-ear seat 9. The ear plate of the single-ear seat 8 is inserted into the double-ear plate at the lower end of the slotted double-ear seat 5, and the double-ear plate at the lower end of the slotted double-ear seat 5 and the ear plate of the single-ear seat 8 are hinged by a pin. The frame 1 is in the unfolded use state. The second support lug 7, fixed to the bottom surface of the corresponding end of the frame 1, is connected to the second double lug seat 9 by a pin, so that the diagonal tie rod 6 supports the unfolded frame 1. When the frame 1 is transported, the pin is pulled out to release the hinge between the second support lug 7 and the second double lug seat 9, and the frame 1 is rotated so that the second support lug 7 is connected to the double lug plate at the upper end of the slotted double lug seat 5 by a pin, so as to lock the frame 1 in the transport state. When the second support lug 7 is connected to the double lug plate at the upper end of the slotted double lug seat 5, the downward-facing diagonal tie rod 6 is rotated to position the mobile diesel generator. The electrical control terminal of the generator room 2; In the above structure, a detachable folding connection structure is adopted between the hinged support and the frame 1 hinged to the electrical control terminal of the mobile diesel generator room 2. In the transportation state, the frame 1 can be folded close to the outer wall of the mobile diesel generator room 2, which greatly reduces the outward extension of the bracket, avoids occupying extra transportation space, improves the loading efficiency of the transportation vehicle, and reduces transportation costs. After folding, the overall length of the equipment can be controlled within the length limit standard of conventional transportation vehicles, without the need for special transportation methods or additional disassembly, reducing transportation difficulty. When the frame 1 is unfolded for use, it is connected to the frame 1 by the detachable hinge through the diagonal tie rod 6 to form a stable triangular support structure. Combined with the frame design of the frame 1 itself, which is composed of longitudinal bars, transverse bars and pillars, it can effectively bear the load of large-diameter and heavy-weight cables, avoid cable displacement or damage, and ensure the safety of power transmission. The connection between the frame 1 and the hinged support is realized by the pin. The unfolding and folding can be switched by inserting and pulling the pin. The operation steps are simple and do not require complicated tools, which facilitates quick on-site operation.

[0019] The swing positioning structure of the diagonal brace 6, which is not connected to the frame 1, is as follows: The single ear seat 8 is a T-shaped plate structure with the large end fixed to the end of the diagonal brace 6 and the small end being semi-circular. When the second support ear 7 is connected to the double ear plate at the upper end of the slotted double ear seat 5, the lower end of the diagonal brace 6 abuts against the corner post of the electrical control end of the mobile diesel generator room 2, and the inner side wall of the lower end of the frame 1 abuts against the large end protrusion of the single ear seat 8, thereby realizing the swing positioning of the diagonal brace 6. In the above structure, under the premise that the upper end of the slotted double ear seat 5 is connected to the second support ear 7, the T-shaped plate structure of the single ear seat 8, together with the corner post of the electrical control end of the mobile diesel generator room 2 and the frame 1, can double limit the diagonal brace 6, avoid shaking during transportation, and ensure structural stability. No additional complex locking components are required, simplifying the design, reducing wear and maintenance costs, and improving the convenience and safety of folding and transportation.

[0020] Working principle To deploy the equipment: Rotate the frame 1 outward around the hinge axis of the support lug 3 and the double lug seat 4 until the frame 1 is horizontal (or at a preset angle that meets the cable support requirements); then, rotate the diagonal tie rod 6 so that the double lug seat 9 at the end of the diagonal tie rod 6 is aligned with the support lug 7 at the bottom of the frame 1, and insert the pin to complete the connection. At this time, the diagonal tie rod 6 provides stable support for the frame 1, the bottom frame 1-1 of the frame 1 can carry the cable, and the side frame 1-2 can prevent the cable from slipping off the side.

[0021] Folding and transporting state: Pull out the pin connecting the second support lug 7 and the second double lug seat 9 to release the support of the diagonal tie rod 6 on the frame 1; rotate the frame 1 inward until the frame 1 is close to the outer wall of the electrical control end of the mobile diesel generator room 2; at this time, align the second support lug 7 of the frame 1 with the double lug plate at the upper end of the slotted double lug seat 5, and insert the pin to lock the frame 1; at the same time, rotate the diagonal tie rod 6 until its lower end abuts against the corner post of the electrical control end of the mobile diesel generator room 2, and the inner side wall of the lower end of the frame 1 abuts against the large end boss of the single lug seat 8 to achieve reliable positioning of the diagonal tie rod 6, prevent the diagonal tie rod 6 from shaking during transportation, and complete the overall folding.
