Description

Technical Field

[0001] This invention relates to the field of substation operation and maintenance technology, specifically to a mechanized leveling system and operation method for outdoor cable trench covers in substations. Background Technology

[0002] In substation construction, outdoor cable trenches are crucial infrastructure for laying and protecting cables. Cable trench covers, as a key component, must provide enclosed protection for the trench while offering a safe and flat working surface for personnel inspection and equipment maintenance. With the expansion of substation construction scale and the improvement of construction standards, higher requirements are placed on the quality of cable trench cover installation, including flatness, consistency, and construction efficiency. However, current practices still have certain shortcomings: Firstly, in the traditional installation of outdoor cable trench covers in substations, lateral shifts often occur after the covers are initially placed. Workers need to adjust their positions by prying with crowbars or pushing them by hand to ensure the flatness of the covers. Due to the large weight of the covers, it is laborious for a single person to operate them. Not only is the labor intensity high, but it is also difficult to unify the direction and force of manual force application. Manual adjustment relies on the experience of workers, and the error differences between different workers are significant. Covers in the same section often have uneven heights and uneven sides. Secondly, the design standards for cable trenches vary among different substations, resulting in a variety of cover widths, thicknesses, and side shapes. When faced with cover plates of different specifications, the construction team needs to prepare multiple sets of equipment, which not only increases equipment procurement and maintenance costs but also prolongs the construction cycle due to frequent debugging, thus hindering the improvement of construction efficiency. In addition, the outdoor construction environment of substations is complex. The surface and surrounding area of ​​cable trench covers are often littered with gravel, soil, concrete residue and other debris, which will affect the leveling of the covers. In traditional construction, a special person needs to be assigned to clean up the debris before the leveling work. This process is disconnected from the leveling work, which increases the manpower input. At the same time, it is not easy to see whether the cover is offset or how much it is offset, which leads to the need for rework and restricts the construction progress. Therefore, it is essential to design a mechanized leveling system and operating method for outdoor cable trench covers in substations. Summary of the Invention

[0003] The purpose of this invention is to provide a mechanized leveling system and operation method for outdoor cable trench covers in substations, in order to solve the problems mentioned in the background art, such as high labor intensity, poor accuracy and unstable error in traditional manual adjustment of covers, high cost and low efficiency due to insufficient equipment adaptability under different specifications of covers, and the disconnection of the pre-operation debris cleaning process and the lack of intuitive visual judgment of cover offset, which easily leads to rework.

[0004] To achieve the above objectives, the present invention provides the following technical solution: In the first aspect, a mechanized leveling system for outdoor cable trench covers in substations is provided, including a vehicle board and a control push rod fixedly connected to the vehicle board. The vehicle board is also equipped with wheels and roller clamps are provided on both sides of the vehicle board. The roller clamps include roller bodies. The roller clamp is mounted on the mounting plate, and the roller body is movably mounted on the mounting plate. The vehicle plate is provided with a slot, which provides space for the movement of the roller clamp and the mounting plate, avoids structural interference, and ensures the freedom of movement for left-right and up-down adjustment. The roller clamp and the mounting plate are both located at the slot position of the vehicle plate. A support frame is fixedly connected to the vehicle panel. The support frame has a sliding groove. The mounting plate is slidably connected to the sliding groove and can slide up and down on the support frame.

[0005] As a further technical solution of the present invention, the left and right movement of the roller body is achieved through the following structure: The system includes a lead screw assembly, which includes a first lead screw and a second lead screw rotatably connected to the mounting plate. The first lead screw and the second lead screw are arranged in parallel and have opposite thread directions. This opposite thread direction design allows the first clamp and the second clamp to move in opposite directions, thereby achieving bidirectional adjustment of the cover plate. The roller clamps set on both sides of the vehicle board include a first clamp and a second clamp. The first clamp is screwed onto a first lead screw and is in sliding engagement with the second lead screw. The second clamp is screwed onto the second lead screw and is in sliding engagement with the first lead screw. Both sides of the mounting plate are fixedly connected to drive motors, which are connected to the lead screw assembly through a transmission structure.

[0006] As a further technical solution of the present invention, the transmission structure includes a gear frame fixedly connected to the mounting plate and a gear set disposed on the gear frame; The gear set includes a first gear fixedly connected to the output shaft of the drive motor and a second gear fixedly connected to the lead screw assembly. The first gear meshes with the second gear, and the gear meshing transmission can stably transmit the power of the drive motor, ensure the smoothness of the lead screw assembly rotation, and improve the accuracy of the left and right adjustment of the roller clamp. The output shaft of the drive motor is rotatably connected to the gear carrier through the first gear, and one end of the lead screw assembly is rotatably connected to the gear carrier through the second gear.

[0007] As a further technical solution of the present invention, the roller clamp also includes a roller frame on which the roller body is rotatably mounted, a connecting seat fixedly connected to the roller frame, and a sliding seat connected to the lead screw assembly; A screw is screwed onto the sliding seat, and the connecting seat is fixedly connected to the screw. When the screw is rotated, the connecting seat drives the roller frame to rotate. The angle of the roller body can be adjusted according to the tilt angle of the cover plate side to make it fully fit with the side of the cover plate, ensuring the accurate direction of the thrust. The sliding seat is slidably connected to the mounting plate.

[0008] As a further technical solution of the present invention, the vertical sliding of the mounting plate is achieved through the following structure: It includes an electric push rod fixedly connected to the support frame. The output end of the electric push rod passes through the support frame and is fixedly connected to the mounting plate. The electric push rod pushes the mounting plate to slide in the slide groove. The slide groove provides guidance and limit for the mounting plate, ensuring the linearity of its up and down movement and ensuring the accuracy of the roller clamp contact height adjustment.

[0009] As a further technical solution of the present invention, it also includes a mud discharge plate disposed on the vehicle plate, the mud discharge plate being located at the front end in the direction of wheel travel. The mud discharge plate includes a collection plate located at the front end of the vehicle plate and an inclined plate located on the side of the vehicle plate. The collection plate and the inclined plate are integrally formed. The collection plate blocks large particles of debris, and the inclined plate guides the debris to the side of the vehicle plate, preventing debris from accumulating on the wheel path and ensuring the vehicle plate moves forward stably. It also includes a laser device installed on the vehicle panel. The laser emission direction of the laser device is consistent with the forward direction of the vehicle panel. The laser beam serves as a visual reference line, allowing staff to intuitively judge the offset of the cover, improving the accuracy and efficiency of the judgment, and assisting in precise adjustments.

[0010] Secondly, a mechanized leveling method for outdoor cable trench covers in substations is provided, including the following steps: S1: Multi-dimensional adjustment of the clamp; S1.1: Left and right position adjustment: Start the drive motors on both sides of the mounting plate, and drive the lead screw assembly to rotate through the transmission structure, so that the first clamp and the second clamp screwed into the lead screw assembly move left and right in opposite directions, and complete the left and right position adaptation of the roller clamp according to the position of the cable trench cover. S1.2: Angle and height adjustment: Rotate the screw on the sliding seat to drive the connecting seat to rotate, so that the roller frame with the roller body installed rotates synchronously with the connecting seat. Adjust the angle of the roller body so that the roller clamp fits and fits the side or edge of the cable trench cover. S1.3: Mounting plate height adjustment: Activate the electric push rod on the support frame to make the mounting plate slide up and down in the groove of the support frame, and adjust the contact height between the roller clamp and the cable trench cover. S2: Cleaning and Visual Preparation; S2.1: Using the mud discharge plate on the vehicle body, the mud and dirt at the front of the wheel in the direction of forward movement are cleaned by collecting the mud with the collection plate and guiding the mud with the inclined plate, so as to ensure that the road ahead of the wheel is flat. S2.2: Activate the laser device on the vehicle panel to align the laser emission direction with the vehicle panel's forward direction, providing visual guidance for a flat cover. S3: Mechanized leveling operation: Push the control lever to make the vehicle plate pass through the wheels, ride on the cable trench cover plate, and move forward along the cable trench cover plate. During the process, the cover plate is pushed towards the center line by the left and right movement of the roller clamps to complete the leveling of the cover plate. S4: Cyclic operation: Repeat S1 to S3 to perform mechanized leveling operations on the entire cable trench cover in sequence.

[0011] As a further technical solution of the present invention, in S1, the angle adjustment of the roller clamp is specifically as follows: the screw is threadedly connected to the sliding seat. When the screw is rotated, the roller frame and the connecting seat rotate with the screw. Moreover, through the thread design of the screw, the rotation state can be locked when the screw is not rotated, so that the tilt angle of the roller body is adjustable.

[0012] As a further technical solution of the present invention, in S1, the electric push rod is used to drive the mounting plate. Since the roller clamp is slidably connected to the mounting plate through the sliding seat, and the sliding seat is connected to the mounting plate through the screw assembly, the roller clamp moves up and down with the mounting plate; and the sliding groove designed in the support frame limits and guides the up and down movement of the mounting plate.

[0013] As a further technical solution of the present invention, in S2, the laser device is fixed to the vehicle panel, and when the vehicle panel moves, it emits a laser beam, enabling the workers to intuitively observe the positional displacement of the cable trench cover and assist in completing the leveling operation.

[0014] Compared with existing technologies, the beneficial effects of this mechanized leveling system and operation method for outdoor cable trench covers in substations are: When the cable trench cover is moved, the drive motor rotates the lead screw assembly, causing the first and second clamps screwed into the lead screw assembly to move left and right in opposite directions. This achieves left and right position matching of the roller clamps, which can be precisely adjusted according to the actual position of the cable trench cover, thereby stably pushing the cover towards the center line. This structure replaces manual adjustment with mechanized operation, which not only saves the trouble of moving the cover manually and makes the operation more labor-saving, but also ensures the flatness accuracy of the cover through the stability of mechanical transmission, solving the problem of cover deviation and difficulty in controlling errors when laying manually. Rotating the screw on the sliding seat drives the connecting seat to rotate, causing the roller frame with the roller body to rotate synchronously, thereby adjusting the angle of the roller body and ensuring that it fits snugly against the side or edge of the cable trench cover. Activating the electric push rod on the support frame allows the mounting plate to slide up and down within the groove of the support frame, adjusting the contact height between the roller clamp and the cable trench cover. This multi-dimensional adjustment design can adapt to cable trench covers of different thicknesses and side shapes, eliminating the need for frequent equipment replacements due to changes in cover specifications and improving the system's versatility. The mud-removal plates on the vehicle platform collect mud and dirt in the direction of the wheels' movement through a collection plate and a tilting plate, ensuring a smooth road surface and avoiding the tedious manual pre-cleaning of the road. This also prevents equipment instability caused by uneven road surfaces, which could reduce work efficiency or affect the leveling effect. The laser device on the vehicle platform emits a laser beam in the same direction as the vehicle platform's movement, allowing workers to visually observe the positional deviation of the cable trench cover. This provides clear visual guidance for the leveling operation, assisting in the precise completion of the leveling operation and significantly improving work efficiency and quality.

[0019] Please see the appendix Figure 5 The present invention provides an embodiment 2: a mechanized leveling operation method for outdoor cable trench covers in substations, comprising the following steps: S1: Multi-dimensional adjustment of the clamp; S1.1: Left and right position adjustment: Start the drive motors 4 on both sides of the mounting plate 3, and drive the lead screw assembly 30 to rotate through the transmission structure, so that the first clamp 201 and the second clamp 202 screwed into the lead screw assembly 30 move left and right in opposite directions, and complete the left and right position adaptation of the roller clamp 2 according to the position of the cable trench cover. S1.2: Angle and height adjustment: Rotate the screw 25 on the sliding seat 24 to drive the connecting seat 23 to rotate, so that the roller frame 22 with the roller body 21 installed rotates synchronously with the connecting seat 23. Adjust the angle of the roller body 21 so that the roller clamp 2 fits and fits the side or edge of the cable trench cover. The angle adjustment of the roller clamp 2 is as follows: the screw 25 is threadedly connected to the sliding seat 24. When the screw 25 is rotated, the roller frame 22 and the connecting seat 23 rotate with the screw 25. And through the thread design of the screw 25, the rotation state can be locked when the screw 25 is not rotated, so that the tilt angle of the roller body 21 is adjustable. S1.3: Height adjustment of mounting plate 3: Activate the electric push rod 132 on the support frame 13 to make the mounting plate 3 slide up and down in the slide groove 131 of the support frame 13, and adjust the contact height between the roller clamp 2 and the cable trench cover; the electric push rod 132 is used to drive the mounting plate 3. Since the roller clamp 2 is slidably connected to the mounting plate 3 through the sliding seat 24, and the sliding seat 24 is connected to the mounting plate 3 through the screw assembly 30, the roller clamp 2 moves up and down with the mounting plate 3; and the slide groove 131 designed in the support frame 13 limits and guides the up and down movement of the mounting plate 3; S2: Cleaning and Visual Preparation; S2.1: Using the mud discharge plate 7 on the vehicle plate 1, the mud and dirt at the front end of the wheel 12 in the forward direction are cleaned by collecting the mud with the collection plate 71 and guiding the mud with the inclined plate 72, so as to ensure that the road ahead of the wheel 12 is flat. S2.2: Activate the laser device 8 on the vehicle platform 1 so that the laser emission direction is consistent with the forward direction of the vehicle platform 1, providing a visual guide for the flatness of the cover; the laser device 8 is fixed on the vehicle platform 1, and emits a laser beam when the vehicle platform 1 moves, so that the staff can intuitively observe the positional displacement of the cable trench cover, and assist in completing the flattening operation.

S4: Cyclic operation: Repeat S1 to S3 to perform mechanized leveling operations on the entire cable trench cover in sequence.

[0020] In summary, this invention, when pushing the trolley plate 1 to move, drives the lead screw assembly 30 to rotate via the drive motor 4, causing the first clamp 201 and the second clamp 202, which are screwed into the lead screw assembly 30, to move left and right in opposite directions, thereby achieving left and right position adaptation of the roller clamp 2. This allows for precise adjustment according to the actual position of the cable trench cover, thus stably pushing the cover towards the center line. This structure replaces manual adjustment with mechanized operation, not only eliminating the tediousness of manually moving the cover and making operation more labor-saving, but also ensuring the flatness accuracy of the cover through the stability of mechanical transmission, solving the problem of easy deviation and difficulty in controlling errors when laying the cover manually. Rotating the screw 25 on the sliding seat 24 drives the connecting seat 23 to rotate, causing the roller frame 22, on which the roller body 21 is mounted, to rotate synchronously, thereby adjusting the angle of the roller body 21 and ensuring that it fits snugly against the side or edge of the cable trench cover. Activating the electric push rod 132 on the support frame 13 causes the mounting plate 3 to slide up and down within the groove 131 of the support frame 13, adjusting the contact height between the roller clamp 2 and the cable trench cover. This multi-dimensional adjustment design can adapt to cable trench covers of different thicknesses and side shapes, eliminating the need for frequent equipment replacements due to changes in cover specifications and improving the system's versatility. The mud discharge plate 7 on the vehicle platform 1 collects mud and dirt at the front of the wheel 12 in the forward direction through the collection plate 71 and the inclined plate 72, ensuring that the road ahead of the wheel 12 is flat. This avoids the tediousness of manually cleaning the road in advance and prevents the equipment from running unstable due to uneven road, which would reduce work efficiency or affect the leveling effect. The laser device 8 on the vehicle platform 1 emits a laser beam in the same direction as the vehicle platform 1, allowing the staff to intuitively observe the positional deviation of the cable trench cover. This provides a clear visual guide for the leveling operation, assists in accurately completing the leveling operation, and greatly improves work efficiency and quality.

S4: Cyclic operation: Repeat S1 to S3 to perform mechanized leveling operations on the entire cable trench cover in sequence.

8. The mechanized leveling operation method for outdoor cable trench covers in substations according to claim 7, characterized in that: In S1, the angle adjustment of the roller clamp (2) is specifically as follows: the screw (25) is threadedly connected to the sliding seat (24). When the screw (25) is rotated, the roller frame (22) and the connecting seat (23) rotate with the screw (25). Through the thread design of the screw (25), the rotation state can be locked when the screw (25) is not rotated, so that the tilt angle of the roller body (21) is adjustable.

9. The mechanized leveling operation method for outdoor cable trench covers in substations according to claim 7, characterized in that: In S1, the electric push rod (132) is used to drive the mounting plate (3). Since the roller clamp (2) is slidably connected to the mounting plate (3) through the sliding seat (24), and the sliding seat (24) is connected to the mounting plate (3) through the screw assembly (30), the roller clamp (2) moves up and down with the mounting plate (3). The slide groove (131) designed in the support frame (13) limits and guides the up and down movement of the mounting plate (3).

10. The mechanized leveling operation method for outdoor cable trench covers in substations according to claim 7, characterized in that: In S2, the laser device (8) is fixed on the vehicle plate (1). When the vehicle plate (1) moves, it emits a laser beam, which enables the staff to visually observe the positional displacement of the cable trench cover and assist in completing the leveling operation.
