Description

Technical Field

[0001] This utility model relates to the field of auxiliary maintenance technology for electrical equipment, specifically an auxiliary maintenance device for electrical equipment in thermal power plants. Background Technology

[0002] Thermal power plants contain a large number of electrical devices. The normal and safe operation of these devices directly affects the power plant's ability to generate electricity. Therefore, when these devices malfunction, they need to be repaired promptly. Since most of these devices are connected to the entire working circuit via cables, maintenance personnel must carry repair tools to the faulty device. Currently, maintenance workers carry these tools in backpacks or large toolboxes. However, since different devices often require many different tools, carrying these tools in backpacks or toolboxes makes them heavy and difficult for maintenance personnel to move around in. Furthermore, the limited capacity of backpacks or toolboxes means that only a small number of tools can be carried. As a result, maintenance personnel often find that they are missing the necessary tools upon arrival at the repair site, forcing them to return to the tool storage location to retrieve them. This significantly impacts maintenance efficiency and increases the workload of maintenance personnel. Utility Model Content

[0003] The purpose of this invention is to provide an auxiliary maintenance device for electrical equipment in thermal power plants to solve the problems mentioned in the background art.

[0004] To achieve the above objectives, this utility model provides the following technical solution: an auxiliary maintenance device for electrical equipment in a thermal power plant, comprising a carriage body, an installation cavity on the top of the carriage body, a pull rod rotatably connected to the outer side of the carriage body, a baffle fixedly connected to the left side of the carriage body, the pull rod being able to press against the top surface of the baffle when rotated to a horizontal position, two first placement baskets symmetrically slidably connected between the inner side walls of the carriage body, two second placement baskets symmetrically connected to the installation cavity, a lifting assembly for lifting the two first placement baskets upwards respectively connected inside the carriage body, a moving assembly for moving the two second placement baskets from the installation cavity to the left and right sides outside the carriage body respectively connected to the carriage body, and a limiting assembly connected to the carriage body for limiting and fixing the two second placement baskets at the installation cavity.

[0005] Preferably, the moving assembly includes two pairs of vertical cavities symmetrically formed on the bottom wall of the mounting cavity. Two rotating arms are symmetrically connected between the front and rear inner walls of the two pairs of vertical cavities via a damping shaft. Two pairs of T-shaped sliders are symmetrically hinged to the tops of the two rotating arms. Two pairs of T-shaped grooves are symmetrically formed at the bottoms of the two second placement baskets. The two pairs of sliders are symmetrically slidably connected within the two grooves. Two sets of guide wheels are symmetrically rotatably connected to the front and rear inner walls of the mounting cavity. The bottoms of the two second placement baskets can slide along the tops of the two sets of guide wheels. The advantage of this arrangement is that by using the two sets of guide wheels to pull the two second placement baskets in opposite directions until the sliders abut against the inner walls of the grooves, continuing to pull the second placement baskets will cause the rotating arms to swing away from the vehicle body until the rotating arms are in a horizontal position. At this point, the second placement baskets can be easily moved to the outside of the vehicle body, exposing the first placement basket for easy access by maintenance personnel to the repair tools inside, thus improving the speed of tool retrieval and placement, and consequently enhancing the convenience and efficiency of maintenance work.

[0006] Preferably, the moving component further includes rectangular cavities symmetrically formed on the top of the two pairs of sliders. Rollers are rotatably connected between the front and rear inner walls of the two pairs of rectangular cavities. The axis of the rollers is parallel to the axis of the guide wheel. The advantage of this arrangement is that the second placement basket can move more smoothly left and right along the guide wheel, thereby saving the physical effort of maintenance personnel when moving the second placement basket and effectively improving the convenience and practicality of the auxiliary maintenance device.

[0007] Preferably, the lifting assembly includes two pairs of push rods symmetrically fixedly connected to the adjacent sides of two pairs of rotating arms. The adjacent ends of the two pairs of push rods pass through the two pairs of vertical cavities and extend into the interior of the vehicle body. The bottoms of the two first placement baskets are respectively pressed against the top surfaces of the two pairs of push rods. The two pairs of push rods are distributed in an inverted V-shape. The advantage of this arrangement is that after a second placement basket is moved from the mounting cavity to the outside of the vehicle body, the two rotating arms will drive the two push rods to swing and lift the first placement basket under the second placement basket upwards, thereby facilitating maintenance personnel to take and put in maintenance tools from the first placement basket and further improving the convenience of maintenance personnel in inspection and repair.

[0008] Preferably, the limiting component includes two limiting grooves symmetrically formed on the bottom wall of the mounting cavity. The inner bottom walls of the two limiting grooves respectively penetrate two pairs of vertical cavities and extend to the lower side of the inner bottom wall of the vertical cavities. Two first limiting plates are symmetrically and movably inserted into the two pairs of limiting grooves. The length of the first limiting plates is greater than the distance between the outermost inner walls of each pair of vertical cavities. Two second limiting plates are symmetrically and fixedly connected to the top of the two first limiting plates. The two second limiting plates are symmetrically and movably inserted into the two limiting grooves. The length of the second limiting plates is less than the distance between the innermost adjacent inner walls of each pair of two vertical cavities. Two rectangular grooves are symmetrically formed on the left and right sides of the carriage body. The innermost adjacent inner walls of the two rectangular grooves penetrate the left and right side walls of the carriage body and are respectively connected to the two limiting grooves. Iron rectangular blocks are symmetrically and slidably connected in the two rectangular grooves. The two rectangular blocks are symmetrically and fixedly connected to the outermost sides of the two first limiting plates. Two magnetic blocks are symmetrically fixedly connected to the left and right sides of the carriage body. After the two rectangular blocks move upward a certain distance, they can be attracted to the two magnetic blocks. The limiting component also includes an iron horizontal plate fixedly connected to the middle of the bottom wall of the mounting cavity. Two magnetic plates are symmetrically fixedly connected to the adjacent sides of the two second placement baskets. The two magnetic plates can be attracted to the left and right sides of the horizontal plate respectively. The advantage of this setting is that when the second placement basket is moved from outside the carriage body to the mounting cavity, the magnetic plates on the sides of the second placement basket will be attracted to the sides of the horizontal plate. At the same time, the rectangular blocks are pushed upward, causing the first limiting plate and the second limiting plate to move upward to the highest point. At this time, the rectangular blocks are attracted and fixed to the magnetic blocks. In this way, the two second placement baskets can be limited, preventing the second placement baskets from sliding from inside the mounting cavity to outside the carriage body during the movement of the carriage body. This ensures that the tools inside the second placement baskets will not fall out, improving the reliability and practicality of the auxiliary maintenance device.

[0009] By adopting the above technical solution, convenient carrying and retrieval of electrical equipment maintenance tools have been achieved.

[0010] Compared with the prior art, the beneficial effects of this utility model are: this auxiliary maintenance device for electrical equipment in thermal power plants, The device is equipped with a carriage body, two first placement baskets, two second placement baskets, a lifting component, and a moving component. This allows maintenance personnel to easily and effortlessly move various necessary maintenance tools by pulling the carriage body, thus saving their physical strength. It also allows all necessary tools to be carried at once, avoiding the need to make multiple trips to retrieve missing tools during maintenance, effectively saving maintenance time and improving efficiency. Maintenance personnel can directly access tools from the two second placement baskets. When tools need to be retrieved from the first placement baskets, the moving component can move the two second placement baskets from the mounting cavity to the left and right sides of the carriage body, exposing the two first placement baskets inside the carriage body. The lifting component then lifts the two first placement baskets upwards, making it easy for personnel to retrieve maintenance tools from both baskets, improving the convenience and reliability of the device.

[0013] 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.

[0014] Please see Figure 1-7 This utility model provides a technical solution: an auxiliary maintenance device for electrical equipment in a thermal power plant, including a carriage 1. The top of the carriage 1 has an installation cavity 11. A pull rod 12 is rotatably connected to the outer side of the carriage 1. A baffle 13 is fixedly connected to the left side of the carriage 1. When the pull rod 12 is rotated to a horizontal position, it can press against the top surface of the baffle 13. Two pairs of universal wheels 14 are symmetrically installed at the bottom of the carriage 1. Two first placement baskets 2 are symmetrically slidably connected between the inner side walls of the carriage 1. Two second placement baskets 3 are symmetrically connected to the installation cavity 11. A lifting component 4 is connected inside the carriage 1 to lift the two first placement baskets 2 upwards respectively. A moving component 5 is also connected to the carriage 1 to move the two second placement baskets 3 from the installation cavity 11 to the left and right sides outside the carriage 1 respectively. A limiting component 6 is connected to the carriage 1 to limit and fix the two second placement baskets 3 at the installation cavity 11.

[0015] refer to Figure 1 , Figure 2 , Figure 3 , Figure 4 and Figure 7 The moving component 5 includes two pairs of vertical cavities 51 symmetrically opened on the bottom wall of the mounting cavity 11. The front and rear inner walls of the two pairs of vertical cavities 51 are symmetrically connected by two rotating arms 52 through a damping pivot. The top ends of the two rotating arms 52 are symmetrically hinged with two pairs of T-shaped sliders 53. The bottom of the two second placement baskets 3 are symmetrically opened with two pairs of T-shaped grooves 54. The two pairs of sliders 53 are symmetrically slidably connected in the two pairs of grooves 54. The front and rear inner walls of the mounting cavity 11 are symmetrically rotatably connected with two sets of guide wheels 55. The bottoms of the two second placement baskets 3 can slide along the top of the two sets of guide wheels 55 respectively.

[0016] Specifically, by using two sets of guide wheels 55 to pull the two second placement baskets 3 in opposite directions until the slider 53 contacts the inner wall of the slide groove 54, pulling the second placement baskets 3 further will cause the rotating arm 52 to swing away from the carriage body 1 until the rotating arm 52 is in a horizontal position. At this point, the second placement baskets 3 can be easily moved to the outside of the carriage body 1, thereby exposing the first placement basket 2 so that maintenance personnel can easily access the maintenance tools inside the first placement basket 2, improving the speed of accessing and placing maintenance tools, and thus improving the convenience and efficiency of maintenance work.

[0017] refer to Figure 3 , Figure 5 and Figure 7 The moving component 5 also includes rectangular cavities symmetrically opened on the top of two pairs of sliders 53. Rollers 56 are rotatably connected between the front and rear inner walls of the two pairs of rectangular cavities. The axis of the rollers 56 is parallel to the axis of the guide wheel 55.

[0018] Specifically, this allows the second placement basket 3 to move more smoothly along the guide wheel 55, thereby saving maintenance personnel the physical effort required to move the second placement basket 3 and effectively improving the convenience and practicality of the auxiliary maintenance device.

[0019] refer to Figure 2 and Figure 5 The lifting assembly 4 includes two pairs of top rods 41 symmetrically fixedly connected to the sides of two pairs of rotating arms 52 that are close to each other. The ends of the two pairs of top rods 41 that are close to each other pass through the two pairs of vertical cavities 51 and extend into the interior of the carriage body 1. The bottoms of the two first placement baskets 2 are respectively pressed against the top surfaces of the two pairs of top rods 41. The two pairs of top rods 41 are distributed in an inverted V-shape.

[0020] Specifically, after a second placement basket 3 is moved from the mounting cavity 11 to the outside of the carriage body 1, the two rotating arms 52 will drive the two push rods 41 to swing and lift the first placement basket 2 on the lower side of the second placement basket 3 upward, so that maintenance personnel can easily take and put maintenance tools from the first placement basket 2, further improving the convenience of maintenance personnel in inspection.

[0021] refer to Figures 1-7The limiting component 6 includes two limiting grooves 61 symmetrically formed on the bottom wall of the mounting cavity 11. The inner bottom walls of the two limiting grooves 61 respectively penetrate two pairs of vertical cavities 51 and extend to the lower side of the inner bottom wall of the vertical cavities 51. Two first limiting plates 62 are symmetrically and movably inserted into the two pairs of limiting grooves 61. The length of the first limiting plates 62 is greater than the distance between the two pairs of vertical cavities 51 away from the inner sidewall. Two second limiting plates 63 are symmetrically and fixedly connected to the top of the two first limiting plates 62. The two second limiting plates 63 are symmetrically and movably inserted into the two limiting grooves 61. The length of the second limiting plates 63 is less than the distance between the two pairs of vertical cavities 51 near the inner sidewall. Two rectangular grooves 64 are symmetrically formed on the left and right sides of the carriage body 1. The inner walls of the two rectangular slots 64, which are close to each other, penetrate the left and right side walls of the carriage body 1 and are connected to the two limiting slots 61 respectively. The two rectangular slots 64 are symmetrically slidably connected to iron rectangular blocks 65. The two rectangular blocks 65 are symmetrically fixedly connected to the two first limiting plates 62 on the opposite sides. The two rectangular blocks 66 are symmetrically fixedly connected to the left and right sides of the carriage body 1. After the two rectangular blocks 65 move upward a certain distance, they can be attracted to the two magnetic blocks 66. The limiting component 6 also includes an iron horizontal plate 67 fixedly connected to the middle position of the bottom wall of the mounting cavity 11. The two second placement baskets 3 are symmetrically fixedly connected to the opposite sides. The two magnetic plates 68 can be attracted to the left and right sides of the horizontal plate 67 respectively.

[0022] Specifically, when the second placement basket 3 is moved from outside the carriage 1 to the mounting cavity 11, the magnetic plate 68 on the side of the second placement basket 3 will be attracted to the side of the horizontal plate 67. At the same time, the rectangular block 65 is pushed upward, causing the first limiting plate 62 and the second limiting plate 63 to move upward to the highest point. At this time, the rectangular block 65 and the magnetic block 66 are attracted and fixed. In this way, the two second placement baskets 3 can be limited, preventing the second placement basket 3 from sliding from inside the mounting cavity 11 to outside the carriage 1 during the movement of the carriage 1. This ensures that the tools inside the second placement basket 3 will not fall out, thus improving the reliability and practicality of the auxiliary maintenance device.
