Description

Technical Field

[0001] This application relates to the technical field of distribution cabinets, and specifically relates to a fixing device for installing municipal distribution cabinets. Background Technique

[0002] A distribution cabinet (also known as a distribution box) is an important device for distributing electric energy in a power system. It is mainly used at the end of the power system and is responsible for safely and effectively distributing electric energy to each electrical equipment. Inside the distribution cabinet, it is usually composed of various components such as switchgear, measuring instruments, protective electrical appliances, and auxiliary equipment. These components work together to achieve the control, protection, and monitoring of the power system; When using a distribution cabinet, it is necessary to transport the distribution cabinet to various points in the city and then fix it to ensure the stable operation of the distribution cabinet; For example, the utility model patent with the publication number CN217769202U specifically discloses a quick installation and fixing structure for a distribution cabinet. When this patent is used, first, a support frame bar is clamped and installed in the support frame at the bottom end of the distribution cabinet, and then shock-absorbing components are set at both ends of the support frame bar. The lifting frame bar and the support frame bar are fixed by fixing screws, thus completing the installation. When in use, the vibration generated by the distribution cabinet squeezes the lifting frame bar to slide vertically in the bottom plate, thereby squeezing the support spring to deform and absorbing the excess vibration, so as to be able to fixedly install and support the distribution cabinet, ensure the stability during the installation of the distribution cabinet, improve the buffering effect, and facilitate quick disassembly and replacement; In the implementation process of the above patent, a large number of bolts are required to fix the distribution cabinet. Although this can increase the stability of the distribution cabinet, a large number of bolts require a long time for staff to install, and when disassembling, the bolts also need to be loosened. If the number of distribution cabinets is small, this operation will not increase much additional time. However, when a large number of distribution cabinets need to be configured in the municipal area, the tightening and loosening operations of the above bolts will consume a lot of time, thus delaying the progress of the work. Therefore, it is necessary to provide a fixing device for installing municipal distribution cabinets to solve the above problems.

[0003] It should be noted that the above information disclosed in this background technical section is only used to understand the background technology of the concept of this application, and therefore, it may include information that does not constitute prior art. Summary of the Invention

[0020] It should be noted that, without conflict, the embodiments in the present application and the features in the embodiments may be combined with each other. The present application will be described in detail below with reference to the drawings and in combination with the embodiments.

[0021] In order to enable those skilled in the art to better understand the solution of the present application, the technical solutions in the embodiments of the present application will be clearly and completely described below with reference to the drawings in the embodiments of the present application. Obviously, the described embodiments are only a part of the embodiments of the present application, rather than all the embodiments. Based on the embodiments in the present application, all other embodiments obtained by those of ordinary skill in the art without making creative efforts shall fall within the protection scope of the present application.

[0022] As Figure 1 - Figure 2 shown, the present application provides a municipal power distribution cabinet installation and fixing device, including a power distribution cabinet 1, which has a wheel body 11. Thus, the power distribution cabinet 1 can be moved to the position where it needs to be installed under the action of the wheel body 11; In order to fix the power distribution cabinet 1, the wheel body 11 can adopt a universal wheel with a self-locking function. Thus, through the self-locking function of the wheel body 11, the power distribution cabinet 1 can be initially fixed; In the present application, the height dimension of the power distribution cabinet 1 is relatively high. Therefore, only through the self-locking function of the wheel body 11, the stability of the power distribution cabinet 1 cannot be guaranteed. In order to further reinforce the power distribution cabinet 1, as Figure 3 shown, square grooves 12 are arranged on all four sides of the bottom of the power distribution cabinet 1. An overhanging mechanism 2 is installed in the square grooves 12. The overhanging mechanism 2 is used to extend the bottom of the power distribution cabinet 1 to the surroundings, so that auxiliary fixing devices can be added at the extended positions to improve the stress position of the bottom of the power distribution cabinet 1, thereby making the power distribution cabinet 1 fixed more stably; As Figure 3 - Figure 5As shown in the figure, the cantilever mechanism 2 includes a connection frame 21 fixedly installed inside the square groove 12. The connection frame 21 can be connected to the power distribution cabinet 1 as a whole by welding. At the same time, the inside of the connection frame 21 is hollow and forms an installation cavity (not shown in the figure). At the same time, a cantilever 22 is slidably arranged in the installation cavity. The cantilever 22 has a sliding end (not marked in the figure) that slidably cooperates with the installation cavity. Thus, by sliding the sliding end in the installation cavity, the cantilever 22 can be moved closer to or farther away from the power distribution cabinet 1. In this application, the position where the cantilever 22 is close to the power distribution cabinet 1 is defined as the storage position, and the position where the cantilever 22 is far from the power distribution cabinet 1 is defined as the fixed position. Therefore, the cantilever 22 can be stored, and when the power distribution cabinet 1 needs to be fixed, the fixing device can be installed on the cantilever 22. At this time, the cantilever 22 is in a position far from the power distribution cabinet 1, thereby making the fixing of the power distribution cabinet 1 more stable; At the same time, a limiting frame 211 is fixedly arranged at a position of the connection frame 21 far from the power distribution cabinet 1. The limiting frame 211 forms a reduced opening. At the same time, a limiting portion (not shown in the figure) is fixedly arranged at the sliding end. The limiting portion is adapted to be restricted by the limiting frame 211 to prevent the cantilever 22 from slipping out of the connection frame 21; As Figure 3 shown in the figure, a limiting mechanism 3 is arranged between the cantilever 22 and the power distribution cabinet 1. The limiting mechanism 3 is used to fix the cantilever 22 in the storage position. The limiting mechanism 3 includes a first hook 31 fixedly installed on the cantilever 22. At the same time, a second hook 33 is fixedly installed on the power distribution cabinet 1, and a chain 32 is installed on the second hook 33. Thus, when the cantilever 22 approaches the power distribution cabinet 1, the other end of the chain 32 can be hooked on the first hook 31 to fix the cantilever 22; It should be noted that when the cantilever 22 is in the fixed position, since a relatively heavy fixing device is installed on the cantilever 22, the cantilever 22 will not move randomly even when it is in a free state. Therefore, when the cantilever 22 is in this position, no additional fixing is required for the cantilever 22; At the same time, two sets of clamping seats 23 are installed on the cantilever 22. The two sets of clamping seats 23 are respectively arranged at both ends of the cantilever 22. A screw 24 is threadedly connected to the clamping seat 23. One end of the screw 24 is installed with a knob 25, and a pressing head 26 is fixedly installed at the other end of the screw 24. Thus, during installation, the knob 25 can be rotated to make the screw 24 approach the cantilever 22, and the cantilever 22 can be clamped through the pressing head 26, thereby fixing the two sets of clamping seats 23 on the cantilever 22; For connecting the fixing device, as Figure 2 - Figure 3 and Figure 5 - Figure 6As shown, a hanging mechanism 4 is installed on the cantilever 22. The hanging mechanism 4 includes a connecting arm 41 fixedly installed inside the clamp seat 23. Two sets of symmetric connecting beams 42 are fixedly installed between the two sets of connecting arms 41. There is a gap between the two sets of connecting beams 42, forming a limiting groove 43. At the same time, an installation gap is formed between the top surface of the connecting beam 42 and the bottom surface of the cantilever 22. A quick-release mechanism 5 is slidably arranged in the limiting groove 43. The quick-release mechanism 5 includes a quick-release cylinder 53. A matching block 54 is fixedly installed on the side of the quick-release cylinder 53. The bottom position of the matching block 54 is lower than the bottom position of the quick-release cylinder 53. And the matching block 54 is adapted to cooperate with the limiting groove 43, so that the quick-release cylinder 53 can be snapped into the limiting groove 43 through the matching block 54 and is located in the installation gap. At the same time, the connecting beam 42 consists of a high-position section 421 at both ends and a low-position section 422 in the middle. The low-position section 422 and the high-position section 421 are both horizontally arranged, and the two are transitioned by a smooth arc. Thus, the bottom surface of the quick-release cylinder 53 can be snapped into the connecting beam 42 from the high-position section 421 and pushed into the low-position section 422. Furthermore, the quick-release cylinder 53 can stably slide into the low-position section 422 and remain in the position of the low-position section 422. And the quick-release cylinder 53 has a through groove 56. A partition 55 is arranged inside the through groove 56, so that the through groove 56 is divided into an upper groove and a lower groove by the partition 55. As Figure 7 - Figure 8 shown, a first spring 52 is fixedly installed in the upper groove of the quick-release cylinder 53. The upper end of the first spring 52 is fixedly installed with a contact cover 51. Thus, during the process of pushing the quick-release cylinder 53 into the connecting beam 42, due to the action of the first spring 52, the contact cover 51 always contacts the bottom of the cantilever 22. Thus, through the action of the upper and lower bottom surfaces of the installation gap, the quick-release cylinder 53 can be clamped. And the first spring 52 is always in a compressed state after the quick-release cylinder 53 is installed, so that it can play a buffering role in the fixation of the power distribution cabinet 1. As Figure 7 - Figure 10 shown, an auxiliary mechanism 7 is installed in the lower groove of the quick-release cylinder 53. The auxiliary mechanism 7 has a connecting column 71 inserted into the lower groove. The connecting column 71 includes an upper connecting body 75 arranged at the upper end. The outer diameter of the upper connecting body 75 is smaller than the outer diameter of the connecting column 71 and forms a placement step. It should be noted that, as Figure 6 shown, an avoidance hole 423 is arranged between the two sets of connecting beams 42. The diameter of the avoidance hole 423 is smaller than the outer diameter of the quick-release cylinder 53 and larger than the inner diameter of the lower groove. Thus, the quick-release cylinder 53 can be lapped on the two sets of connecting beams 42 to maintain stability, and the upper connecting body 75 can be inserted into the lower groove through the avoidance hole 423. On both sides of the bottom of the quick-release cylinder 53, shrinkage grooves 531 are provided. A sliding column 58 is slidably installed in the shrinkage groove 531. It should be noted that one end of the sliding column 58 is fixedly installed with a sliding block 57. The bottom end of the sliding block 57 is provided with an inclined surface 571. At the same time, the upper end of the sliding column 58 is provided with a horizontal plane 572. When the connecting column 71 moves from bottom to top, the top of the upper connecting body 75 will first come into contact with the inclined surface 571; The mutually remote sides of the sliding columns 58 slide in the inner wall of the quick-release cylinder 53. A second spring 59 is sleeved on the surface of the sliding columns 58. The two ends of the second spring 59 are respectively fixedly connected to the sliding block 57 and the inner wall of the shrinkage groove 531. Thus, when the sliding block 57 is squeezed, it will slide into the shrinkage groove 531, and the second spring 59 is compressed. When the external force is removed, the sliding block 57 is reset under the action of the second spring 59. It should be noted that in the initial state, one end of the sliding block 57 is already outside the shrinkage groove 531, and a small part of the sliding block 57 is still located in the shrinkage groove 531. Thus, when the sliding block 57 moves, it will not come out of the shrinkage groove 531; As Figure 7 and Figure 9 shown, at the same time, a first ring 72 is fixedly installed on the top of the upper connecting body 75. The outer diameter of the first ring 72 is adapted to the inner diameter of the through groove 56. And a first arc 721 used in cooperation with the inclined surface 571 is provided on the first ring 72. The bottom of the first ring 72 is provided with a horizontal first contact surface, which is mainly used in cooperation with the horizontal plane 572; Continue to refer to Figure 9 , a second ring 73 is slidably installed on the surface of the upper connecting body 75. The outer diameter of the second ring 73 is the same as the outer diameter of the first ring 72. At the same time, a second arc 731 used in cooperation with the inclined surface 571 is provided on the second ring 73. And a second contact surface is provided on the upper part of the second ring 73, which is also horizontally arranged and is mainly used in cooperation with the first contact surface. In the initial state, due to the action of gravity, the second ring 73 freely falls onto the placement step. At this time, there is a certain distance between the second ring 73 and the first ring 72. When an external force acts, the second ring 73 is adapted to move upward. When the first contact surface and the second contact surface are mutually attached, at this time, the distance between the first ring 72 and the second ring 73 is the closest. And a third spring 74 is fixedly installed between the first ring 72 and the second ring 73. The third spring 74 is used to maintain the positions of the first ring 72 and the second ring 73 in the initial state. At the same time, a spring groove (not shown in the figure) is provided at the bottom of the first ring 72. Thus, the third spring 74 can be completely retracted into the spring groove, and the first ring 72 and the second ring 73 are attached; When the power distribution cabinet 1 is not reinforced, the connecting column 71 has not been installed in the quick-release cylinder 53 yet. At this time, personnel are required to install the connecting column 71. During installation, the staff only need to hold the connecting column 71 by hand and align the upper connecting body 75 with the quick-release cylinder 53 and then push it in. During the upward movement of the connecting column 71, the first ring 72 first contacts the inclined surface 571 and exerts a squeezing effect on it. The sliding block 57 retracts into the contraction groove 531 under the squeezing action of the first ring 72. When the first ring 72 completely enters the quick-release cylinder 53, the first ring 72 separates from the sliding block 57. At this time, under the action of the second spring 59, the sliding block 57 resets. After the staff push the first ring 72 into the quick-release cylinder 53, they can release the connecting column 71. Under the action of gravity, the connecting column 71 will move downward. Finally, the first contact surface contacts the horizontal plane 572, and the first ring 72 overlaps on the sliding column 58. At this time, even if the connecting column 71 is subjected to a downward force, due to the restriction of the horizontal plane 572 on the first contact surface, the first ring 72 will not come out of the quick-release cylinder 53. At this time, the lower half of the connecting column 71 protrudes from the quick-release cylinder 53, and the first contact surface contacts the horizontal plane 572; As Figure 2 - Figure 3 shown, a threaded hole (not shown in the figure) is provided at the bottom of the connecting column 71. A support mechanism 8 is installed inside the threaded hole. The support mechanism 8 is used to assist in supporting and fixing the power distribution cabinet 1. The support mechanism 8 includes a vertical rod 82 threadedly installed inside the threaded hole. A base 81 is fixedly installed at the bottom of the vertical rod 82. Thus, after the connecting column 71 is installed in the quick-release cylinder 53, by rotating the vertical rod 82, the base 81 can be made to contact and abut against the ground, thereby supporting and fixing the power distribution cabinet 1; At the same time, a nut 83 is threadedly installed at the upper end of the vertical rod 82. Thus, after the base 81 contacts the ground, the position of the vertical rod 82 can be fixed by the nut 83; And a weight 6 is sleeved on the lower end of the vertical rod 82. The weight 6 can be placed on the upper end of the base 81 to increase the weight of the base 81, thereby increasing the stability of the fixation of the power distribution cabinet 1. And because the weight 6 is relatively heavy, even if the cantilever 22 is in a free state, it will not move randomly; Furthermore, the base 81 can be set as a magnet, and the weight 6 is made of a magnetic material, thereby increasing the stability of the installation of the weight 6.

[0023] When the power distribution cabinet 1 needs to be moved, the connecting column 71 needs to be removed from the through groove 56. At this time, the staff only needs to push the second ring 73 upward through tools such as a center point. It should be noted that due to the setting of the second arc 731 and the inclined surface 571, the second ring 73 will also produce a squeezing effect on the sliding block 57 during the upward movement. The staff continuously pushes the second ring 73 upward, and the second contact surface fits with the first contact surface. At this time, the sliding block 57 is completely retracted into the contraction groove 531. After the second contact surface fits with the first contact surface, the staff still needs to continue to push the ejector pin. Under the action of the ejector pin, the second ring 73 abuts against the bottom of the first ring 72 and pushes the first ring 72 upward. At this time, the entire connecting column 71 moves upward until the upper connecting body 75 abuts against the lower end of the partition plate 55. During this process, the first ring 72 and the second ring 73 are connected as a whole and always press the sliding block 57 in the contraction groove 531; Under the action of gravity, the connecting column 71 moves downward and then disengages from the through groove 56, thereby realizing the disassembly of the connecting column 71.

[0024] The above are only the preferred embodiments of the present application and are not used to limit the present application. For those skilled in the art, the present application can have various changes and modifications. Any modification, equivalent replacement, improvement, etc. made within the spirit and principle of the present application shall be included in the protection scope of the present application.
