Technical Field
[0001] This utility model relates to the field of secondary screen cabinet handling technology, and in particular to a labor-saving device for handling secondary screen cabinets. Background Technology
[0002] Secondary control cabinets are specialized cabinets used in power systems to install secondary equipment such as relay protection, automatic devices, and measurement and control equipment. They are an important component of the secondary system in substations or distribution rooms. Electrical connections between equipment are achieved through internal busbars. In smart substations, they undertake key functions such as data acquisition, status monitoring, and remote control. They are hub nodes connecting primary equipment and automation systems. Internally, they integrate modules such as microcomputer protection devices, measurement and control units, and switches, and are key support equipment for the safe operation of smart grids.
[0003] In the current process of moving secondary equipment cabinets, since cranes cannot be used for hoisting indoors, most of the time it is done manually. Although this method can complete the placement of the secondary equipment cabinets, it is time-consuming and laborious, and there is a risk of injury to the secondary equipment cabinets and the personnel involved in the moving process. In addition, most secondary equipment rooms currently use prefabricated cabin structures. Due to the relatively narrow space in the prefabricated cabins, it is not convenient for construction and handling, which increases the difficulty of construction in the prefabricated cabins.
[0004] Therefore, the aforementioned method of manual lifting is time-consuming and laborious, and carries the risk of injury to the secondary cabinets and lifting personnel during the lifting process. Furthermore, the limited space in the prefabricated cabin increases the difficulty of construction within the cabin. By setting up a composite base plate and a double-track system, efficient and labor-saving handling of the cabinets can be achieved. This method is suitable for handling secondary cabinets in prefabricated cabins and other environments, reducing the risk of damage to the secondary cabinets themselves and injury to lifting personnel during handling, and improving the efficiency of secondary cabinet handling. Utility Model Content
[0005] To overcome the problems of laborious and time-consuming manual lifting of secondary equipment cabinets, which poses a risk of injury to the cabinets and personnel, and the fact that most secondary equipment rooms currently use prefabricated cabin structures, which are relatively narrow and difficult to move during construction, thus increasing the difficulty of construction in prefabricated cabins.
[0006] The technical solution of this utility model is as follows: a labor-saving device for moving secondary cabinets, including a prefabricated cabin body and a support rail. A partition plate is welded and fixed at the center of the inner wall of the prefabricated cabin body. The partition plate and the prefabricated cabin body are an integrated structure. A cabin door is rotatably connected to the side of the prefabricated cabin body. The support rail is set at the bottom of the inner wall of the prefabricated cabin body. An auxiliary bracket is welded and fixed to the outer side of the support rail near the cabin door. An auxiliary roller is rotatably connected to the outer side of the auxiliary bracket.
[0007] Preferably, the hatches are symmetrically distributed on the prefabricated cabin body, and the support rails are evenly distributed on the bottom of the inner wall of the prefabricated cabin body.
[0008] Preferably, mounting ears are welded and fixed to the side of the support track. The mounting ears are symmetrically and alternately distributed on both sides of the support track. The mounting ears are located at the bottom of the inner wall of the prefabricated cabin body. The top surface of the mounting ears is provided with mounting holes. The inner wall of the mounting holes is connected to fixing bolts by threads. The mounting ears are threadedly connected and fixed to the bottom of the inner wall of the prefabricated cabin body by fixing bolts.
[0009] Preferably, the inner wall of the prefabricated cabin body is slidably connected to a composite base plate, the top surface of the composite base plate is connected and installed with a rubber anti-slip pad, and the bottom surface of the composite base plate is provided with positioning holes, which are symmetrically distributed on the composite base plate.
[0010] Preferably, a limiting track is welded and fixed to the bottom surface of the composite base plate. The limiting track is symmetrically distributed on the composite base plate. A roller bracket is welded and fixed to the outer side of the end of the limiting track away from the auxiliary roller. A support roller is rotatably connected to the outer side of the roller bracket. The support roller is in contact with the outer surface of the support track. The auxiliary roller is in contact with the outer surface of the limiting track.
[0011] Preferably, a rotating seat is welded and fixed to the bottom surface of the composite base plate near the auxiliary roller. The rotating seats are symmetrically distributed on the bottom surface of the composite base plate. A damping shaft is fixedly connected to the inner wall of the rotating seat. A rotating support is rotatably connected to the outer side of the damping shaft. An anti-slip foot is fixedly connected to the end of the rotating support.

[0013] The beneficial effects of this utility model are:
[0014] 1. After the composite base plate is fully pulled out, rotate the rotating support downwards to a vertical position so that the anti-slip feet are in contact with the ground, providing support for the composite base plate and ensuring the stability of the cabinet during handling. The symmetrically distributed limiting rails and support rails form a double-rail guide structure, and the support rollers and auxiliary rollers form a four-point contact to evenly distribute the weight of the composite base plate and cabinet. Furthermore, the rolling friction between the support rollers and auxiliary rollers and the limiting rails and support rails makes it easier to move the secondary cabinet into the prefabricated compartment.
[0015] 2. During the process of pushing the composite base plate, the limit pin will re-exit the positioning hole, and the bottom of the prefabricated compartment will push the rotating support to rotate upward to a horizontal position, so as not to affect the movement of the composite base plate, making it easy to smoothly transport the cabinet into the prefabricated compartment, until the limit pin is re-inserted into the positioning hole, to prevent the composite base plate from sliding due to external interference, which would affect the stability of the cabinet.

[0022] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.
[0023] Please see Figures 1-5This utility model provides an embodiment: a labor-saving device for moving secondary cabinets, including a prefabricated cabin body 1 and a support rail 4. A partition plate 2 is welded and fixed at the center of the inner wall of the prefabricated cabin body 1. The partition plate 2 and the prefabricated cabin body 1 are an integrated structure. A cabin door 3 is rotatably connected to the side of the prefabricated cabin body 1. The support rail 4 is set at the bottom of the inner wall of the prefabricated cabin body 1. An auxiliary bracket 5 is welded and fixed to the outer side of the support rail 4 near the cabin door 3. An auxiliary roller 6 is rotatably connected to the outer side of the auxiliary bracket 5.
[0024] The hatch 3 is symmetrically distributed on the prefabricated cabin body 1, and the support rails 4 are evenly distributed on the bottom of the inner wall of the prefabricated cabin body 1. During the secondary cabinet handling process, the sliding path is formed by the evenly distributed support rails 4. The weight of the cabinet is distributed to the support rollers 109 through the composite base plate 104, and then transferred to the bottom of the prefabricated cabin through the support rails 4 and auxiliary rollers 6.
[0025] Mounting ears 101 are welded and fixed to the side of the support rail 4. The mounting ears 101 are symmetrically and alternately distributed on both sides of the support rail 4. The mounting ears 101 are set at the bottom of the inner wall of the prefabricated cabin body 1. The top surface of the mounting ears 101 has mounting holes 102. The inner wall of the mounting holes 102 is connected to the fixing bolts 103 by threads. The mounting ears 101 are threadedly connected and fixed to the bottom of the inner wall of the prefabricated cabin body 1 by the fixing bolts 103. The staggered mounting ears 101 achieve detachable fixing of the support rail 4 by fixing bolts 103. By aligning the mounting holes 102 on the mounting ears 101 with the reserved holes at the bottom of the prefabricated cabin body 1, and then inserting the fixing bolts 103 and tightening them, the support rail 4 and the prefabricated cabin body 1 are installed and fixed.
[0026] The inner wall of the prefabricated cabin body 1 is slidably connected to a composite base plate 104. A rubber anti-slip pad 105 is installed on the top surface of the composite base plate 104. Positioning holes 106 are opened on the bottom surface of the composite base plate 104. The positioning holes 106 are symmetrically distributed on the composite base plate 104. The composite base plate 104 provides support to the secondary cabinet. The rubber anti-slip pad 105 increases the friction between the secondary cabinet and the composite base plate 104, ensuring the stability of the secondary cabinet.
[0027] A limiting track 107 is welded and fixed to the bottom surface of the composite base plate 104. The limiting track 107 is symmetrically distributed on the composite base plate 104. A roller bracket 108 is welded and fixed to the outer side of the limiting track 107 away from the auxiliary roller 6. A support roller 109 is rotatably connected to the outer side of the roller bracket 108. The support roller 109 is in contact with the outer surface of the support track 4. The auxiliary roller 6 is in contact with the outer surface of the limiting track 107. The symmetrically distributed limiting track 107 and support track 4 form a double-track guide structure. The support roller 109 and auxiliary roller 6 form a four-point contact, which evenly distributes the weight of the composite base plate 104 and the cabinet. Furthermore, through the rolling friction between the support roller 109 and auxiliary roller 6 and the limiting track 107 and support track 4, the secondary cabinet can be moved into the prefabricated compartment with less effort.
[0028] A rotating seat 110 is welded and fixed to the bottom surface of the composite base plate 104 near the auxiliary roller 6. The rotating seats 110 are symmetrically distributed on the bottom surface of the composite base plate 104. A damping rotating shaft 111 is fixedly connected to the inner wall of the rotating seat 110. A rotating support 112 is rotatably connected to the outer side of the damping rotating shaft 111. An anti-slip foot 113 is fixedly connected to the end of the rotating support 112. When the cabinet needs to be moved, after the composite base plate 104 is pulled outward, the rotating support 112 is rotated downward to a vertical position, so that the anti-slip foot 113 is in contact with the ground, providing support for the composite base plate 104 and ensuring that the cabinet is placed stably. When the composite base plate 104 with the cabinet is placed is pushed into the prefabricated compartment, the bottom of the prefabricated compartment will push the rotating support 112 upward to a horizontal position, so as not to affect the movement of the composite base plate 104, making it easy to move the cabinet into the prefabricated compartment smoothly.
[0029] A limiting seat 114 is welded and fixed to the bottom of the inner wall of the prefabricated cabin body 1. The limiting seat 114 is located near the auxiliary roller 6. A limiting spring 115 is fixedly connected to the bottom of the inner wall of the limiting seat 114. A limiting pin 116 is fixedly connected to the top of the limiting spring 115. The limiting pin 116 is slidably connected to the inner wall of the limiting seat 114. The limiting pin 116 is engaged with the positioning hole 106. The elastic force of the limiting spring 115 pushes the limiting pin 116 to engage with the positioning hole 106, thereby limiting the composite base plate 104.
[0030] Working principle: According to Figures 3-4 As shown, during operation, by aligning the mounting hole 102 on the mounting ear 101 with the reserved hole at the bottom of the prefabricated cabin body 1, and then inserting and tightening the fixing bolt 103, the support rail 4 is installed and fixed to the prefabricated cabin body 1. The composite base plate 104 is then transported into the prefabricated cabin, so that the auxiliary roller 6 and the support roller 109 abut against and fit against the limiting rail 107 and the support rail 4 respectively, and the limiting pin 116 is inserted into the positioning hole 106.
[0031] according to Figures 1-5 As shown, when the cabinet needs to be moved into the prefabricated compartment, the composite base plate 104 is pulled outward. Due to the arc-shaped structure of the head of the limiting pin 116, the composite base plate 104 will push the limiting pin 116 out of the positioning hole 106 when it moves, releasing the restriction of the composite base plate 104. Until the composite base plate 104 is completely pulled out, the limiting pin 116 is reinserted into the positioning hole 106 under the action of the limiting spring 115 to restrict the composite base plate 104 and prevent it from moving when the cabinet is moved onto the composite base plate 104.
[0032] according to Figures 2-5 As shown, after the composite base plate 104 is fully pulled out, the rotating support 112 is rotated downwards to a vertical position, so that the anti-slip feet 113 are in contact with the ground, providing support for the composite base plate 104 and ensuring the stability of the cabinet during transportation. The symmetrically distributed limiting rails 107 and supporting rails 4 form a double-rail guide structure, and the supporting rollers 109 and auxiliary rollers 6 form a four-point contact, which evenly distributes the weight of the composite base plate 104 and the cabinet. Furthermore, through the rolling friction between the supporting rollers 109 and auxiliary rollers 6 and the limiting rails 107 and supporting rails 4, the secondary cabinet can be transported into the prefabricated compartment with less effort.
[0033] according to Figures 2-5 As shown, during the subsequent pushing of the composite base plate 104, the limiting pin 116 will re-exit the positioning hole 106, and the bottom of the prefabricated compartment will push the rotating support 112 to rotate upward to a horizontal position, so as not to affect the movement of the composite base plate 104, making it easy to smoothly transport the cabinet into the prefabricated compartment, until the limiting pin 116 is re-inserted into the positioning hole 106, preventing the composite base plate 104 from sliding due to external interference, which would affect the stability of the cabinet.
