Technical Field

[0001] This utility model relates to the field of electrical construction equipment technology, and in particular to an electrical construction hoisting frame. Background Technology

[0002] During electrical construction, it is often necessary to hoist heavy electrical equipment such as electrical cabinets. The existing method is to install lifting rings on the top of the electrical cabinets and other electrical equipment. However, the top plate of the electrical cabinet often deforms and becomes detached, causing the product to fall and be damaged. Therefore, hoisting frames are often used in electrical construction.

[0003] A search revealed, for example, a utility model with publication number CN218231518U, which discloses an electrical construction hoisting frame, including a base plate. The top of the base plate is provided with two limiting protective plates. The base plate is internally provided with a drive assembly, which is connected to the two limiting protective plates. The drive assembly is used to drive the two limiting protective plates to move back and forth. This utility model requires the electrical equipment to be hoisted to be placed on the top of the base plate before hoisting. However, the existing electrical equipment is relatively heavy. Therefore, placing it on the top of the base plate or removing it from the top of the base plate requires manual lifting, which is inconvenient in daily operation and requires a lot of manpower.

[0004] In conclusion, developing an electrical construction hoisting frame that assists workers in suspending electrical equipment is a problem that urgently needs to be solved by those skilled in the art. Utility Model Content

Detailed Implementation

[0024] 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.

[0025] To enable those skilled in the art to better understand the present invention, the present invention will be further described in detail below with reference to the accompanying drawings and specific embodiments.

[0026] This utility model provides an electrical construction hoisting frame; please refer to the appendix to the instruction manual. Figure 1 With appendix Figure 2The electrical construction hoisting frame includes a hoisting frame 1, inside which electrical equipment is installed. A movable groove 101 is provided on the bottom surface of the inner cavity of the hoisting frame 1. A first threaded rod 103 and a sliding rod 102 are provided within the movable groove 101. The first threaded rod 103 and the sliding rod 102 are arranged parallel to each other. A conveying plate 106 is threadedly connected to the first threaded rod 103. Rotating the first threaded rod 103 moves the conveying plate 106. Furthermore, a sliding rod 102 is also installed within the conveying plate 106, which limits the direction of movement of the conveying plate 106. The bottom surface of the inner cavity of the hoisting frame 1 extends outward along the direction of the sliding rod 102. A transmission plate is provided at the end of the bottom surface of the inner cavity of the hoisting frame 1. The transmission plate can transport the electrical equipment onto the conveying plate 106. When the workers are hoisting the electrical equipment, they rotate the first threaded rod 103. Since the first threaded rod 103 is fixed in the movable groove 101 and its position is locked, the conveyor plate 106, which is threaded to the first threaded rod 103, moves outward along the slide rod 102 in a preset direction. After the conveyor plate 106 is connected to the transmission plate, the workers transfer the conveyor plate 106 onto the conveyor plate 106 through the transmission plate. The electrical equipment can move together with the conveyor plate 106. At this time, the first threaded rod 103 is rotated again to move the conveyor plate 106 closer to the inner cavity of the hoisting frame 1. After the conveyor plate 106 moves into the inner cavity of the hoisting frame 1, the assembly of the electrical equipment and the electrical construction hoisting frame is completed. The electrical equipment can then be hoisted to the target position together with the electrical construction hoisting frame.

[0027] Please refer to the instruction manual appendix. Figure 3 The conveyor plate 106 extends upwards on both sides, with the extension direction perpendicular to the conveyor plate 106. Two telescopic rods 1061 are installed on each of the extended portions on both sides. The extension direction of each telescopic rod 1061 points towards the inside of the conveyor plate 106, and the telescopic rods 1061 are perpendicular to the slide rod 102. The ends of the two telescopic rods 1061 on the same side are connected to a lower clamping plate 1062, which can fit against the side wall of the electrical equipment. A second threaded rod 1063 is provided between two adjacent telescopic rods 1061. The second threaded rod 1063 is parallel to the telescopic rod 1061, and one end of the second threaded rod 1063 is threaded. On the extension of the conveyor plate 106, the other end of the second threaded rod 1063 is engaged with the end face of the lower clamping plate 1062. Each second threaded rod 1063 can rotate within each lower clamping plate 1062. When the electrical equipment is placed on the conveyor plate 106, each second threaded rod 1063 is screwed on so that the second threaded rod 1063 abuts against the lower clamping plate 1062 and moves toward the inside of the conveyor plate 106. The lower clamping plates 1062 on both sides of the conveyor plate 106 clamp and fix the electrical equipment, ensuring that there is no relative sliding between the conveyor plate 106 and the electrical equipment or avoiding the electrical equipment from shifting when the conveyor plate 106 drives the electrical equipment to move.

[0028] Please refer to the instruction manual appendix. Figure 4Lifting holes 1011 are provided on both side walls of the hoisting frame 1. Lifting blocks 1013 are slidably connected to each lifting hole 1011, and electric actuators 1012 are fixedly connected to each lifting block 1013. The output end of the electric actuator 1012 passes through the lifting block 1013 and extends into the inner cavity of the hoisting frame 1. An upper clamping plate 1015 is connected to the output end of each electric actuator 1012. The electric actuator 1012 can push the upper clamping plate 1015 to move in a direction perpendicular to the sliding rod 102, allowing the upper clamping plate 1015 to abut against the side wall of the electrical equipment. Furthermore, a third threaded rod 1014 is provided on the top wall of the hoisting frame 1. The third threaded rod 1014 is oriented along the height direction of the hoisting frame 1, extends into the lifting hole 1011, and connects to the lifting block 1013. The third threaded rod 1014 is threadedly connected to the side wall of the hoisting frame 1. The third threaded rod 1014 can rotate relative to the lifting block 1013. Twisting the third threaded rod 1014 adjusts the length of the third threaded rod 1014 extending into the lifting hole 1011, thereby changing the position of the lifting block 1013 in the lifting hole 1011. This allows the upper clamping plate 1015 connected to the lifting block 1013 to abut against different positions of the electrical equipment. When the electrical equipment is placed on the conveyor plate 106, the lower end of the electrical equipment is clamped by each of the second threaded rods 1063. At the same time, the third threaded rod 1014 is twisted according to the height of the electrical equipment so that the lifting block 1013 connected to the third threaded rod 1014 corresponds to the top of the electrical equipment. At this time, the electric push rod 1012 inside the lifting block 1013 is activated. The electric push rod 1012 drives the upper clamping plate 1015 to abut against the electrical equipment, further fixing the electrical equipment in its setting state on the conveyor plate 106.

[0029] Please refer to the instruction manual appendix. Figure 5A connecting block 1021 is hinged to the side wall port of the hoisting frame 1, meaning the connecting block 1021 can rotate around the edge of the hoisting frame 1. A fixing rail 1022 is connected to the connecting block 1021, and the fixing rail 1022 can move together with the connecting block 1021. When the electrical equipment is placed into the hoisting frame 1, the fixing rail 1022 is rotated to allow the conveyor plate 106 to move the electrical equipment without obstruction. When the conveyor plate 106 transfers the electrical equipment into the hoisting frame 1, the fixing rail 1022 is closed to lock the electrical equipment inside the hoisting frame 1. It should be noted that a limiting hole 1023 is provided on the side of the hoisting frame 1 away from the connecting block 1021. A limiting block 1024 is also provided on the end face of the hoisting frame 1 corresponding to the limiting hole 1023. The limiting block 1024 is rotatably connected to the hoisting frame 1, and the limiting block 1024 is connected to the hoisting frame 1. The frame 1 is spaced out, meaning that when the fixed rail 1022 is closed, the limiting hole 1023 is closer to the lifting frame 1 than the limiting block 1024. Furthermore, the limiting block 1024 and the limiting hole 1023 are shaped to match, and the limiting block 1024 and the limiting hole 1023 are set at the same angle. The limiting block 1024 can fit into the limiting hole 1023 and pass through the limiting hole 1023. At this time, the fixed rail 1022 with the limiting hole 1023 can be opened smoothly. When the limiting block 1024 is rotated so that the limiting block 1024 and the limiting hole 1023 are set at a certain angle, the limiting block 1024 abuts against the outer end face of the limiting hole 1023, and the fixed rail 1022 cannot be opened. The electrical equipment is locked inside the lifting frame 1. Preferably, both the limiting block 1024 and the limiting hole 1023 can be rectangular.

[0030] Preferably, the bottom surface of the inner cavity of the hoisting frame 1 extends outward along the direction of the slide bar 102, and the thickness gradually decreases at the end of the extension to form an inclined surface. A transmission plate is provided on this inclined surface. The transmission plate includes several evenly arranged movable rollers 104. Each movable roller 104 can rotate around its own axis, so that the electrical equipment rolls and rubs against each movable roller 104. The electrical equipment can be more easily transported to the conveyor plate 106 that docks with the transmission plate. Each movable roller 104 is connected to a drive rotor. The drive rotor is started so that the movable roller 104 automatically transports the electrical equipment to the conveyor plate 106. A motor 105 is provided on the end face of the hoisting frame 1 away from the transmission plate. The output shaft of the motor 105 is connected to the first threaded rod 103. The motor 105 controls the movement of the conveyor plate 106, further reducing labor intensity.

[0031] Four lifting rings 2 are provided at the top of the lifting frame 1. Each lifting ring 2 is located at one of the four vertices of the lifting frame 1. The lifting equipment is connected to each lifting ring 2 to transport the lifting frame 1 and its internal electrical equipment to the target location. Furthermore, a handle is connected to one end of the second threaded rod 1063 and the third threaded rod 1014 that extends outward from the lifting frame 1. The handle can be easily turned to simplify the installation and fixing process of the electrical equipment.

[0032] In one embodiment of this application, the electrical equipment to be hoisted is placed at the end of the transmission plate. Then, the limiting block 1024 is screwed on so that the end face of the limiting block 1024 coincides with the limiting hole 1023, allowing the limiting block 1024 to pass smoothly through the limiting hole 1023. The fixing rail 1022 is rotated to open the hoisting frame 1. The handle connected to the first threaded rod 103 is rotated to push the conveying plate 106 out of the inner cavity of the hoisting frame 1 through the first threaded rod 103, so that the conveying plate 106 aligns with the transmission plate at the end of the bottom extension of the hoisting frame 1. At this time, the movable roller 104 of the conveying plate 106 is started to rotate, transferring the electrical equipment placed on the conveying plate 106 to the conveying plate 106. Then, the handle of the second threaded rod 1063 is screwed on so that the lower clamping plate 1062 connected to the second threaded rod clamps the electrical equipment. The side wall of the equipment is stabilized to ensure the electrical equipment is in a stable position. After the electrical equipment is fixed, the handle of the first threaded rod 103 is turned again, and the conveyor plate 106 transports the electrical equipment to the inside of the hoisting frame. According to the height of the electrical equipment, the handle of the third threaded rod 1014 is turned so that the lifting block 1013 corresponds to the upper end of the electrical equipment. The electric push rod 1012 inside the lifting block 1013 is activated so that the upper clamping plate 1015 connected to the electric push rod 1012 clamps the electrical equipment, ensuring that the electrical equipment does not swing during the hoisting process. The fixing railing 1022 is closed and the limiting block 1024 is turned. The electrical equipment and the hoisting frame 1 are assembled. The hoisting equipment is attached to the lifting ring 2 on the hoisting frame 1, and the hoisting equipment hoists the hoisting frame 1 and the electrical equipment together to the target position.

[0033] It should be noted that in this specification, relational terms such as first and second are used only to distinguish one entity from several other entities, and do not necessarily require or imply any such actual relationship or order between these entities.

[0034] This article uses specific examples to illustrate the principles and implementation methods of this utility model. The descriptions of the above embodiments are only for the purpose of helping to understand the method and core ideas of this utility model. It should be noted that for those skilled in the art, several improvements and modifications can be made to this utility model without departing from the principles of this utility model, and these improvements and modifications also fall within the protection scope of this utility model.
