DETAILED DESCRIPTION

The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

As shown in FIGS. 1 to 4 , this embodiment provides a medium-voltage overhead line pole-mounted cable quick access box, which includes an access box body 1 and an adjustable mechanism 2 .

The access box 1 is an existing device, and the electrical components and wiring settings inside the access box 1 are not described in detail here. The upper end of the access box 1 is provided with a plurality of quick-connect plugs for connecting the wiring of the access box 1.

The adjustable mechanism 2 includes a sliding part 3, a connecting part 4 and a driving part 5; the sliding part 3 is slidably connected in the sliding groove 11 on the medium voltage overhead line pole; as shown in Figures 1-2, one side of the sliding part 3 is installed in the access box 1 through the connecting part 4, and the driving part 5 is installed on the other side of the sliding part 3. As shown in Figures 2-4, the output end of the driving part 5 is engaged with the tooth groove 12 on the medium voltage overhead line pole, and is used to drive the access box 1 to move up and down along the medium voltage overhead line pole. Among them, the driving part 5 cooperates with the tooth groove 12 on the medium voltage overhead line pole, and the driving part 5 drives the sliding part 3 to slide up and down in the sliding groove 11 on the medium voltage overhead line pole, and the sliding part 3 is connected to the access box 1 through the connecting part 4. When the sliding part 3 moves vertically, it synchronously drives the entire access box 1 to move vertically, thereby achieving the effect of changing the up and down movement of the access box 1, which is convenient for the staff to change the current position height of the access box 1 according to the actual situation.

In order to improve the sliding efficiency of the sliding part 3, as shown in Figures 1 and 2, in this embodiment, the sliding part 3 includes a connecting shell 31; the connecting shell 31 is a U-shaped shell, and an inner convex block 311 matching the sliding groove 11 is formed on the connecting shell 31, and two extension plates 312 are formed at the end of the connecting shell 31, and the driving part 5 is arranged between the two extension plates 312. Among them, the connecting shell 31 adopts a U-shaped shell, and the inner convex block 311 is arranged, which is used for sliding connection in the sliding groove 11, so that the sliding efficiency of the entire connecting shell 31 can be improved, and a guiding effect can be formed; secondly, two extension plates 312 are formed at the end of the connecting shell 31, which is convenient for installing the driving part 5 in the extension plate 312.

To facilitate the installation of the connection shell 31 and the access box 1, as shown in Figures 1 and 2, in this embodiment, two rows of fixing blocks 32 are provided on one side of the connection shell 31 and the connection part 4, and first through holes 321 are provided on the fixing blocks 32. The fixing rods 33 can be inserted between the upper and lower fixing blocks 32 through the first through holes 321, and the fixing blocks 32 and the connection part 4 are detachably connected through the fixing rods 33. The connection part 4 includes a connection plate 41 and a loading block 42; one side of the loading block 42 is fixedly connected to the back of the access box 1, and the other side is fixedly connected to the connection plate 41, and a plurality of second through holes 411 cooperating with the first through holes 321 are provided on the connection plate 41, and the connection plate 41 is an arc-shaped plate body that can fit the outer surface of the connection shell 31.

The connecting plate 41 is an arc-shaped plate, and is provided with a second through hole 411 that matches the first through hole 321, so that the detachable effect can be achieved, and installation and removal are very convenient. After the connecting plate 41 is attached to the outer surface of the connecting shell 31, it is located between the upper fixed block 32 and the lower fixed block 32. The fixing rod 33 passes through the first through hole 321 of the upper fixed block 32, the second through hole 411 on the connecting plate 41, and the first through hole 321 on the lower fixed block 32 in sequence, so as to achieve the purpose of installing the access box 1 on one side of the sliding part 3 through the connecting part 4. In this way, when the connecting shell 31 slides up and down on the column, the entire access box 1 can be synchronously driven to slide up and down.

In order to improve the driving efficiency of the driving unit 5, as shown in Figures 2, 3 and 4, in this embodiment, the driving unit 5 includes a motor 51, a worm 52 and a worm wheel 53; the output end of the motor 51 is connected to the worm 52, the worm 52 is rotatably mounted between the two extension plates 312, the lower end of the worm 52 is meshed with the worm wheel 53, and the worm wheel 53 is meshed with the tooth groove 12 set on the medium voltage overhead line pole. A support frame 54 is fixed to the outer side of the two extension plates 312, and the motor 51 is installed on the support frame 54; a limit plate 511 is fixed between the two extension plates 312, the worm 52 is rotatably mounted on the limit plate 511, and passes through the limit plate 511; the worm wheel 53 is rotatably connected between the two extension plates 312 through the shaft 531.

The motor 51 drives the worm 52 to rotate, and the worm 52 drives the worm wheel 53 to operate. The worm wheel 53 engages with the tooth groove 12 set on the medium-voltage overhead line pole, thereby driving the entire connection shell 31 to slide upward, thereby achieving the effect of changing the height of the access box 1. It should be noted that the tooth profile shape in the tooth groove 12 in this embodiment must be able to match the tooth shape of the worm wheel 53 when it is manufactured. A support frame 54 is set on the outside of the two extension plates 312 to carry the motor 51, which ensures the stability of the motor 51 during operation and facilitates later maintenance.

The working principle of the medium voltage overhead line pole cable quick access box is as follows:

As shown in Figures 1 to 4, when the height of the access box 1 needs to be adjusted, the motor 51 is started, the motor 51 drives the worm 52 to rotate, and the worm 52 drives the worm wheel 53 to rotate between the two extension plates 312. Since the outer side of the worm wheel 53 is meshed with the tooth groove 12 set on the medium-voltage overhead line pole, it can drive the entire connection shell 31 to move vertically upward on the medium-voltage overhead line pole along the arrangement direction of the tooth groove 12. Since a sliding groove 11 is provided on the medium-voltage overhead line pole, and an inner protrusion 311 is provided on the inner wall of the connection shell 31, the cooperation between the inner protrusion 311 and the sliding groove 11 can effectively improve the movement of the entire connection shell 31 on the medium-voltage overhead line pole to form a guide, and when the connection shell 31 is in an upward movement, it synchronously drives the access box 1 to move upward. On the contrary, when it is necessary to lower the height of the access box 1 later, it is only necessary to drive the motor 51 to rotate in the reverse direction to drive the connecting shell 31 to move downward, thereby lowering the height of the access box 1; the medium-voltage overhead line pole cable quick access box is easy to operate, and the height of the access box 1 can be adjusted according to actual conditions, thereby greatly improving the working efficiency of the access box 1.

Although embodiments of the present invention have been shown and described, it will be appreciated by those skilled in the art that various changes, modifications, substitutions and variations may be made to the embodiments without departing from the principles and spirit of the present invention, and that the scope of the present invention is defined by the appended claims and their equivalents.
