Description

Technical Field

[0001] This invention relates to the field of electrical distribution box installation technology, specifically an auxiliary device for installing a distribution box in a manhole. Background Technology

[0002] Distribution boxes, as metal cabinets that house switching equipment, measuring instruments, protective electrical appliances, and auxiliary equipment installed according to electrical wiring requirements, are characterized by their small size, easy installation, special technical performance, fixed location, unique configuration functions, lack of site restrictions, widespread application, stable and reliable operation, high space utilization, small footprint, and environmental benefits. Distribution cabinets can be classified according to their structural features and uses into fixed panel switch cabinets, protective switch cabinets, drawer-type switch cabinets, and power and lighting distribution control boxes. Distribution boxes can rationally distribute electrical energy, facilitate circuit opening and closing operations, provide a high level of safety protection, and intuitively display the circuit's continuity status.

[0003] Originally, a manhole referred to a tubular, vertically installed underground water supply and drainage facility used for water intake or groundwater protection. With the continuous improvement of building standards and the increasing demands of residents, high-rise residential buildings have a large number of electrical devices on each floor. These devices need to form various electrical systems, making distribution boxes, an essential component of these systems, widely used. By connecting various cables and electrical equipment through distribution boxes for power transmission and control, electrical manholes or vertical shafts are formed in building construction, the most common being distribution boxes or distribution rooms.

[0004] The existing distribution boxes used in the manholes require lifting them to the installation height and drilling holes to locate them. However, the distribution boxes are heavy and the space inside the manholes is narrow, which makes it difficult for construction workers to locate and drill the boxes. This also results in low safety and is time-consuming and labor-intensive. Summary of the Invention

[0005] To overcome the shortcomings of existing methods that involve lifting the distribution box to the installation position for positioning and installation in pipe wells, such as limitations imposed by the weight of the distribution box itself and the space inside the pipe well, making it difficult for construction personnel to position and drill holes, resulting in low safety and being time-consuming and labor-intensive, this application provides an auxiliary device for installing distribution boxes in pipe wells. By placing a coarse height adjustment component inside the pipe well and placing the distribution box on top of the support platform on the fine height adjustment component, the device uses existing control methods to control the scissor bracket, coarsely adjusting the height of the fine height adjustment component located at the top of the top plate, and operating jacks to slowly raise the support platform at the top of the top plate, thereby raising the distribution box to the precise installation position. This process uses coarse and fine adjustments to control the height of the distribution box inside the pipe well, providing strong controllability and helping to reduce the pressure and difficulty of installing distribution boxes inside pipe wells.

[0006] The technical solution adopted by the embodiments of this application to solve its technical problem is:

[0007] An auxiliary device for installing a distribution box in a manhole includes a height fine adjustment component, a height coarse adjustment component, and a leveling component. The height fine adjustment component is used to support the distribution box to be installed.

[0008] The coarse height adjustment component is located at the bottom of the fine height adjustment component;

[0009] The leveling component is located at the bottom of the coarse height adjustment component;

[0010] The coarse height adjustment component and the fine height adjustment component work together to control the movement of the distribution box mounted on top of the fine height adjustment component from bottom to top. The leveling component controls the tilt of the distribution box on top of the fine height adjustment component from the bottom of the fine height adjustment component and the coarse height adjustment component.

[0011] In one possible implementation, the height coarse adjustment component includes a scissor bracket with a top plate mounted on its top and a bottom plate mounted on its bottom. One side of the scissor bracket moves closer to or further away from the top and bottom plates to control the distance between the top and bottom plates.

[0012] In one possible implementation, the height adjustment component includes a lateral movable portion and a longitudinal movable portion, the longitudinal movable portion controlling the height of the lateral movable portion, and the lateral movable portion controlling the distance between the distribution box and the well installation position.

[0013] In one possible implementation, the lateral movable part includes a support platform, with storage grooves machined at the bottom of both ends of the support platform. Multiple support pulleys are fixedly connected to the top inner wall of the storage grooves. The longitudinal movable part includes a support platform, with support bars welded to both ends of the top of the support platform. A jack is located at the center of the bottom of the support platform. Two lifting rods are welded to both sides of the bottom of the support platform. The jacks are assembled to the top of the top plate. The support bars have a right-angled trapezoidal cross-section. The top inner wall of the support pulleys is an inclined plane parallel to the top of the support bars. The bottom ends of the multiple support pulleys are respectively supported on the tops of the two support bars. The four lifting rods are slidably connected to the inside of the top plate and movably connected to the inside of the scissor bracket.

[0014] In one possible implementation, the top of the bearing platform is welded to both sides with a first stop bar and a second stop bar. Each of the two second stop bars has a limiting groove machined in the middle. Both sides of the top of the support platform are welded to a stop block. The two second stop bars are located inside the two first stop bars. The second stop bar and the first stop bar on one side are respectively located on both sides of the support bar. The bearing platform is movably connected to the top of the two stop blocks and cooperates with the two stop blocks through the two limiting grooves on the two second stop bars at the bottom of its two sides to limit the movement distance of the bearing platform on the top of the support platform.

[0015] In one possible implementation, a fixed seat is welded to the top center of one side of the support platform. An adjusting screw is internally threaded onto the fixed seat. One end of the adjusting screw is provided with a slide, and the other end of the adjusting screw is assembled with a fixed control arm. Multiple rollers are provided at both ends of one side of the slide. A limiting groove is machined on the other side of the slide. A storage groove is machined at the center of one side of the bearing platform. A buckle is machined on the inner wall of one side of the storage groove. Multiple rollers are supported on the inner wall of one side of the storage groove, allowing the slide to slide up and down inside the buckle. The adjusting screw is located on one side of the narrow end of the top support bar of the support platform, and one end of it is supported on the inner wall of one side of the limiting groove.

[0016] In one possible implementation, two parallel limiting strips are machined on the top of both ends of the bearing platform. A straightening plate is hinged to the top of one side of the bearing platform, and an overlapping plate is welded to the top of one side of the straightening plate. The straightening plate and the storage groove are located on the same side of the bearing platform. The bottom of one side of the overlapping plate rests on the top of the slide, and the straightening plate is stored inside the bearing platform.

[0017] In one possible implementation, the leveling assembly includes a frame, a movable plate hinged to the top of one side of the frame, a support seat hinged to the inside of the other side of the frame, a connecting seat hinged to the side of the movable plate away from its hinge point with the frame, a leveling screw threadedly connected to the inside of the connecting seat, a movable control arm plugged into the top of the leveling screw, casters for moving the frame on the ground at the four corners of the bottom of the frame, a top of the movable plate assembled to the bottom of the base plate, a bottom end plugged into the support seat and rotating within it, and a movable control arm sliding within the leveling screw.

[0018] In one possible implementation, limit pins are movably connected to the interior of both sides of the frame, and the top surface of the limit pins is machined with a pad and a control rod, the pad and the control rod being perpendicular to each other.

[0019] In one possible implementation, slides are machined inside both sides of the movable plate, and the two pads are respectively overlapped on the top of both sides of the base plate. When the movable plate rotates about its hinge point with the frame, it moves outside the two limit pins through the two slides machined inside it.

[0020] The beneficial effects of this application are as follows:

[0021] Firstly, in this solution, the coarse height adjustment component is placed inside the manhole using a leveling component, and the distribution box is placed on top of the support platform on the fine height adjustment component. The existing control method is used to control the scissor bracket, coarsely adjusting the height of the fine height adjustment component located at the top of the roof plate, and operating jacks to slowly raise the support platform at the top of the roof plate, thereby raising the distribution box to the precise installation position. This process uses coarse and fine adjustment to control the height of the distribution box inside the manhole, which is highly controllable and helps to reduce the pressure and difficulty of constructing the distribution box inside the manhole.

[0022] Secondly, in this solution, by adjusting the threaded connection between the adjusting screw and the fixed seat, the adjusting screw moves away from the slide. With the weight of the bearing platform itself, the support pulley rolls along the inclined plane at the top of the support bar. When the bearing platform moves to one side, it also moves to the bottom. With the slide at one end of the adjusting screw supporting the overlapping plate, the straightening plate rotates and tilts around its hinge with the bearing platform. The position of the distribution box is corrected by the straightening plate, which is simple and convenient.

[0023] Thirdly, in this solution, the threaded connection between the adjusting screw and the fixed seat is adjusted so that one end of the adjusting screw applies pressure to the slide block inside the limiting groove, causing the slide block to push the bearing platform to move to one side on the top of the support platform. With the cooperation of the support pulley and the inclined surface of the support bar, the bearing platform moves the distribution box closer to the installation position of the distribution box inside the pipe well. This makes it easier to calibrate the drilling angle at all times when drilling inside the pipe well, which helps to improve drilling accuracy and increase the efficiency of distribution box assembly.

[0024] Fourth, in this solution, by adjusting the threaded connection between the leveling screw and the connecting seat, the end of the leveling screw inserted inside the support seat can rotate. When the control connecting seat and the support seat are far apart, the movable plate can rotate around its hinge point with the frame and tilt. Thus, when the frame is on an inclined ground, the height fine adjustment component and the height coarse adjustment component are in a horizontal state, which facilitates the vertical rise of the distribution box inside the manhole, thereby ensuring safety.

[0039] The technical solution in this application embodiment is to solve the problems mentioned in the background art, and the overall idea is as follows:

[0040] Example 1:

[0041] This embodiment describes the specific structure of an auxiliary device for installing a well distribution box. See details below. Figure 1 , Figure 2 and Figure 9 As shown, it includes a height fine-adjustment component 1 for supporting the distribution box to be installed, a height coarse-adjustment component 2 set at the bottom of the height fine-adjustment component 1, and a leveling component 3 set at the bottom of the height coarse-adjustment component 2. The height coarse-adjustment component 2 includes a scissor bracket 202, a top plate 201 is assembled on the top of the scissor bracket 202, and a bottom plate 203 is assembled and connected to the bottom of the scissor bracket 202. The height fine-adjustment component 1 includes a horizontal movable part and a vertical movable part. The horizontal movable part includes a bearing platform 101, and the vertical movable part includes a support platform 104. A jack 120 is set at the center of the bottom of the support platform 104.

[0042] Among them, the height coarse adjustment component 2 adopts existing technology and controls one side of the scissor bracket 202 to move closer or further away from the other side between the top plate 201 and the bottom plate 203 in the form of a hydraulic cylinder, thereby controlling the distance between the top plate 201 and the bottom plate 203, so as to achieve the effect of raising the height fine adjustment component 1 and lowering the height fine adjustment component 1.

[0043] At the same time, such as Figure 9 As shown, the jack 120 is assembled and connected to the top of the top plate 201. When the jack 120 is used to control the support platform 104 to drive the bearing platform 101 to move to the top, the distribution box mounted on the top of the bearing platform 101 can be raised, so that the longitudinal moving part controls the height of the lateral moving part. This makes it easier for the coarse height adjustment component 2 and the fine height adjustment component 1 to cooperate in controlling the distribution box mounted on the top of the fine height adjustment component 1 to move from the bottom to the top, so that the distribution box is accurately raised to the target installation position.

[0044] Secondly, in order to control the movement path of the support platform 104 when it is lifted by the jack 120, such as Figure 9As shown, two lifting slide rods 119 are welded to both sides of the bottom of the support platform 104, so that all four lifting slide rods 119 are slidably connected to the inside of the top plate 201, and all four lifting slide rods 119 are movably connected to the inside of the scissor bracket 202, so as to avoid interfering with the movement of the scissor bracket 202.

[0045] By adopting the above technical solution:

[0046] The above design places the coarse height adjustment component 2 inside the manhole and the distribution box on top of the support platform 101 on the fine height adjustment component 1. The distance between the two sides of the scissor bracket 202 is controlled by the existing control method, thereby controlling the distance between the top plate 201 and the bottom plate 203. The fine height adjustment component 1 is raised to the approximate height inside the manhole, and the jack 120 is operated to slowly raise the support platform 104 on top of the top plate 201, thereby raising the distribution box on top of the support platform 101 to the actual installation position. This process is highly controllable and accurate, which helps to reduce the pressure and difficulty of the construction of the distribution box in the manhole, thereby improving construction efficiency.

[0047] Example 2:

[0048] Based on Embodiment 1, this embodiment describes the specific structure of the bearing platform 101 and the support platform 104, such as... Figure 1 , Figures 6 to 11 Support bars 110 are welded to both ends of the top of the support platform 104, and storage grooves 118 are machined at the bottom of both ends of the bearing platform 101. Multiple support pulleys 107 are fixedly connected to the top inner wall of the storage grooves 118.

[0049] Among them, such as Figure 5 As shown, the cross-section of the support bar 110 is a right trapezoid, and as... Figure 9 As shown, the top inner wall of the support pulley 107 is an inclined surface parallel to the top of the support bar 110. The bottom ends of the multiple support pulleys 107 are respectively supported on the top of the two support bars 110. When the control platform 101 moves on the top of the two support bars 110, the support platform 101 in the transverse movable part can control the distance between the distribution box and the installation position of the pipe well. At the same time, with the guidance of the inclined surface at the top of the support bar 110, the support platform 101 can be raised to facilitate the installation of the distribution box near the installation position of the pipe well from the top to the bottom.

[0050] like Figure 5 and Figure 10 As shown, the top of the bearing platform 101 is welded to both sides with a first stop bar 106 and a second stop bar 109. The middle of the two second stop bars 109 is machined with a limit groove 122. The top of the support platform 104 is welded to both sides with a stop block 121.

[0051] Among them, the two second stop bars 109 are located inside the two first stop bars 106, while the second stop bar 109 and the first stop bar 106 located on one side are respectively located on both sides of the support bar 110, which can restrict the bearing platform 101 from moving along the long side of the support platform 104, ensuring that the bearing platform 101 can only move along the short side at the top of the support platform 104.

[0052] Meanwhile, the carrying platform 101 is movably connected to the top of the two stops 121, and cooperates with the two stops 121 through the two limiting slots 122 on the two second stops 109 on both sides of its bottom, which can limit the movement distance of the carrying platform 101 on the top of the support platform 104 and prevent the carrying platform 101 from slipping off the top of the support platform 104 when it moves along the support platform 104.

[0053] like Figures 5 to 8 As shown, a fixed seat 105 is welded to the top center of one side of the support platform 104. An adjusting screw 115 is internally threaded to the fixed seat 105. A slide 112 is provided at one end of the adjusting screw 115, and a fixed control arm 117 is assembled to the other end of the adjusting screw 115. Multiple rollers 116 are provided at both ends of one side of the slide 112. A storage groove 108 is machined at the center of one side of the bearing platform 101. The adjusting screw 115 is located on one side of the narrow end of the top support bar 110 of the support platform 104.

[0054] In this way, by controlling the fixed control arm 117 at one end of the adjusting screw 115 to adjust the threaded connection between the adjusting screw 115 and the fixed seat 105, the slide 112 can be pushed to apply pressure to the bearing platform 101. When the multiple rollers 116 on the slide 112 roll on one side of the inner wall of the receiving groove 108, the bearing platform 101 can move upward along the top slope of the support bar 110 on the top of the support platform 104, and at the same time move to one side to move closer to the well installation position, so as to gradually confirm whether there is a deviation in the opening position when opening the well installation position.

[0055] Meanwhile, in order to ensure that the multiple rollers 116 on one side of the slide 112 can stably contact the inner wall of one side of the storage slot 108, such as Figure 6 As shown, a limiting groove 114 is machined on the other side of the slide 112, and a buckle 113 is machined on the inner wall of one side of the storage groove 108. By supporting the slide 112 on the inner wall of one side of the storage groove 108 with multiple rollers 116, the slide 112 slides up and down inside the buckle 113. One end of the adjusting screw 115 is supported on the inner wall of one side of the limiting groove 114, which restricts the slide 112 from moving to the bottom inside the buckle 113 without the pressure of the adjusting screw 115.

[0056] Secondly, in order to control the position of the distribution box on top of the support platform 101, so that the edge of the distribution box is parallel to the long side of the support platform 101, such as... Figure 5 As shown, two parallel limiting strips 102 are machined on the top of both ends of the bearing platform 101. A straightening plate 103 is hinged to the top of one side of the bearing platform 101, and an overlapping plate 111 is welded to the top of one side of the straightening plate 103. By setting the straightening plate 103 and the storage groove 108 on the same side of the bearing platform 101, so that they are stored inside the bearing platform 101, and the bottom of the overlapping plate 111 rests on the top of the slide block 112, the straightening plate 103 can be flipped up by rotating around its hinge point with the bearing platform 101 after the bearing platform 101 moves down along the slope of the support strip 110 via the support pulley 107.

[0057] At the same time, by making the edges of the distribution box fit into the surface of the straightening plate 103, the distribution box can be positioned so that the long side of the distribution box is parallel to the long side of the support platform 101. This makes it easier to refer to the angle between the support platform 101 and the installation position of the manhole, thereby determining the angle between the distribution box and the target installation position.

[0058] By adopting the above technical solution:

[0059] The above design adjusts the threaded connection between the adjusting screw 115 and the fixed seat 105, causing the adjusting screw 115 to move away from the slide 112. With the weight of the bearing platform 101 itself, the support pulley 107 rolls along the inclined plane at the top of the support bar 110, causing the bearing platform 101 to move away from the installation position of the distribution box. This causes the bearing platform 101 to move towards the bottom. The slide 112 at one end of the adjusting screw 115 supports the overlapping plate 111, causing the straightening plate 103 to rotate and tilt around its hinge with the bearing platform 101. The surface of the straightening plate 103 fits against the edges of the distribution box, thereby correcting the position of the distribution box.

[0060] Simultaneously, the distribution box mounted on the top of the bearing platform 101 is raised to the installation position inside the manhole using the height fine adjustment component 1 and the height coarse adjustment component 2. By adjusting the threaded connection between the adjusting screw 115 and the fixed seat 105, one end of the adjusting screw 115 applies pressure to the slide 112 inside the limiting circular groove 114, causing the slide 112 to push the bearing platform 101 to move to one side on the top of the support platform 104. With the help of the inclined surface of the support pulley 107 and the support bar 110, the bearing platform 101 moves the distribution box closer to the installation position of the distribution box inside the manhole, which is convenient for calibrating the drilling angle at all times when drilling inside the manhole.

[0061] In addition, when drilling is completed on the inner wall of the well for the installation of the distribution box, it is only necessary to control the bearing platform 101 on the top of the support platform 104 to move the distribution box closer to the installation position. After the distribution box is fixed in the target position, it is only necessary to release the bearing platform 101 on the top of the support platform 104 to reset it, which is simple and convenient.

[0062] Example 3:

[0063] Based on Embodiments 1 and 2, this embodiment describes the specific structure of the leveling component 3, such as... Figures 1 to 4 As shown, the leveling component 3, which controls the tilt of the top distribution box of the height fine adjustment component 1 at the bottom of the height fine adjustment component 1 and the height coarse adjustment component 2, includes a frame 302. A movable plate 301 is hinged to the top of one side of the frame 302. The top of the movable plate 301 is assembled to the bottom of the base plate 203. A support seat 309 is hinged to the inside of the other side of the frame 302. A connecting seat 310 is hinged to the inside of the movable plate 301 on the side away from its hinge point with the frame 302. A leveling screw 307 is threaded to the inside of the connecting seat 310. A movable control arm 308 is plugged into the top of the leveling screw 307.

[0064] The bottom end of the leveling screw 307 is plugged into the inside of the support base 309. By controlling the movable control arm 308 to adjust the threaded connection between the leveling screw 307 and the connecting seat 310, the bottom end of the leveling screw 307 can rotate inside the support base 309. This allows the support base 309 to rotate inside the frame 302. When the connecting seat 310 rotates inside the movable plate 301, the movable plate 301 is controlled to rotate around the hinge point on the top of the frame 302. Thus, when the frame 302 is placed on a plane and is in an inclined state, the movable plate 301 is controlled to drive the coarse height adjustment component 2 and the fine height adjustment component 1 to a horizontal state.

[0065] Meanwhile, by allowing the movable control arm 308 to slide inside the leveling screw 307, it is convenient to control the rotation of the leveling screw 307 inside the connecting seat 310 while ensuring the basic length of the movable control arm 308.

[0066] Secondly, by installing casters at the four corners of the bottom of the frame 302, the frame 302 can move the height fine adjustment component 1 and the height coarse adjustment component 2 on the ground, which makes it convenient to use this application to move the distribution box.

[0067] Meanwhile, limit pins 304 are movably connected to the interior of both sides of the frame 302. The top surface of the limit pin 304 is machined with a pad 305 and a control rod 306. The pad 305 and the control rod 306 are perpendicular to each other. The interior of both sides of the movable plate 301 is machined with a slide rail 303. By having the two pads 305 overlap the top of both sides of the base plate 203, the limit pins 304 can be suspended inside the interior of both sides of the frame 302. When the control rod 306 is used to rotate the limit pins 304 and the pads 305 are disengaged from the top of the base plate 203, the limit pins 304 can fall and contact the ground. With the help of the rough ground, the stability of the four casters after locking can be increased.

[0068] Furthermore, when the movable plate 301 rotates about its hinge point with the frame 302, the movable plate 301 can move outside the two limit pins 304 by means of two slides 303 machined inside it.

[0069] By adopting the above technical solution:

[0070] The above design controls the rotation of the leveling screw 307 via the movable control arm 308, adjusting the threaded connection between the leveling screw 307 and the connecting seat 310. This causes the end of the leveling screw 307 inserted inside the support seat 309 to rotate, applying pressure to the support seat 309 and controlling the connecting seat 310 and the support seat 309 to move away from each other. This allows the movable plate 301 to rotate around its hinge point with the frame 302, thereby tilting the top of the movable plate 301 using the height fine adjustment component 1 and the height coarse adjustment component 2. This ensures that when the frame 302 is on an inclined surface, the height fine adjustment component 1 and the height coarse adjustment component 2 are kept in a horizontal position, thus guaranteeing the safety of the distribution box rising inside the manhole.

[0071] Specifically, when using the auxiliary device for installing the distribution box in this manhole:

[0072] Positioning and installation auxiliary device: Use the four casters at the bottom of the frame 302 to move the device to the bottom of the manhole and lock the casters. Rotate the limit pin 304 through the control rod 306 to disengage the bottom of the pad 305 from the top of the base plate 203, so that the bottom end of the limit pin 304 is supported on the ground.

[0073] Meanwhile, when the frame 302 is on an inclined ground, the leveling screw 307 is rotated by the movable control arm 308, and the threaded connection between the leveling screw 307 and the connecting seat 310 is adjusted so that the bottom end of the leveling screw 307 applies pressure to the support seat 309, increasing the distance between the connecting seat 310 and the support seat 309. This allows the movable plate 301 to rotate around its hinge point with the frame 302 and tilt, so that both the height fine adjustment component 1 and the height coarse adjustment component 2 are in a vertical state.

[0074] Erect the distribution box and correct its position: Erect the distribution box between the two limit bars 102 at the top of the support platform 101, adjust the threaded connection between the adjusting screw 115 and the fixed seat 105, so that the adjusting screw 115 moves away from the slide 112. With the help of the weight of the support platform 101 itself, the support pulley 107 rolls along the inclined surface at the top of the support bar 110. When the support platform 101 moves to the bottom, the slide 112 at one end of the adjusting screw 115 supports the overlapping plate 111, so that the straightening plate 103 rotates and tilts around its hinge with the support platform 101, ensuring that the long edge of the bottom of the distribution box is in contact with the surface of the straightening plate 103.

[0075] Raise the distribution box inside the manhole: Use the existing control method to control the distance between the two sides of the scissor bracket 202, thereby controlling the distance between the top plate 201 and the bottom plate 203. Raise the top height fine adjustment component 1 inside the manhole to the approximate height, and operate the jack 120 to slowly raise the support platform 104 on the top of the top plate 201, raising the distribution box on the top of the bearing platform 101 to the actual installation position.

[0076] Controlling the distance between the distribution box and the installation position of the manhole, and determining the drilling position: Adjusting the threaded connection between the adjusting screw 115 and the fixed seat 105, so that one end of the adjusting screw 115 applies pressure to the slide 112 inside the limiting groove 114, causing the slide 112 to push the bearing platform 101 to move to one side on the top of the support platform 104. With the help of the inclined surface of the support pulley 107 and the support bar 110, the bearing platform 101 moves the distribution box closer to the installation position of the distribution box in the manhole, confirming the drilling position, and determining the drilling accuracy by repeating this step.

[0077] Finally, it should be noted that the above embodiments are merely examples for clearly illustrating the present invention and are not intended to limit the implementation. Those skilled in the art will recognize that other variations or modifications can be made based on the above description. It is neither necessary nor possible to exhaustively list all possible implementations. However, obvious variations or modifications derived therefrom are still within the scope of protection of this invention.
