Detailed Description
The present invention will be described in detail with reference to the accompanying drawings.
As shown in fig. 1-3, the utility model discloses a two protection semi-rings 1, protection semi-ring 1 middle part all is equipped with the cross-section and is concave type block portion 101, and as shown in fig. 2, the recess and the 6 marginal gomphosis of cable shaft of block portion 101, protection semi-ring 1 both ends all are equipped with connecting plate 102, and as shown in fig. 2, connecting plate 102 is located the well head upside of cable shaft 6 to as shown in fig. 3, the connecting plate 102 that two protection semi-rings 1 correspond the side links to each other through bolt 3 and nut 4, and the cover is equipped with spacing spacer 2 that can open and shut on the bolt 3 between two protection semi-ring 1 correspondence side connecting plates 102, as shown in fig. 2 protection semi-ring 1 inboard and upper and lower marginal surface and block portion 101 surface all is equipped with elasticity inoxidizing coating 103, in this embodiment, elasticity inoxidizing coating 103 is formed by.
As shown in fig. 4 to 5, the spacing sleeve 2 includes two half spacing sleeves, one end of each of the two half spacing sleeves is hinged through a hinge shaft 201, and the other end of each of the two half spacing sleeves is provided with a fixing plate 202, when the spacing sleeve 2 is mounted on the bolt 3, in this embodiment, the fixing plates 202 of the two half spacing sleeves are connected through a spacing sleeve bolt and nut assembly 203, and the fixing plates 202 can also be designed to be fixedly connected through other structures such as a clamping groove and a clamping block as required.
As shown in fig. 2, the length L of the spacing spacer 21Equal to the length L of the side edge of the groove of the clamping part 1012After the limiting spacer 2 is dismounted, enough space for the protection semi-ring 1 to go in and out of the cable well 6 and move in the cable well 6 can be ensured, and when the limiting spacer 2 is mountedThe clamping parts 101 of the two protection semi-rings 1 can be ensured to abut against the edge of the cable well 6 without loosening, and the length L of the two sides of the well mouth of the cable well 6 can be ensured to be removed1Most of the edge outside the part is wrapped by the protection half ring 1, and the cable 5 can freely select different directions to enter the cable well 6. Because the well head size of the cable well 6 is the national standard size, the length of the spacing spacer 2 can also be standardized.
The utility model discloses a theory of operation does:
as shown in fig. 6, when underground cable laying is performed in the prior art, the cable 5 is inserted into the underground installation room from the cable well 6 and is inserted into the cable duct 7, and due to the heavy weight of the cable 5, an operator can only drag the cable 5 to move in the cable well 6, which may cause the insulating skin on the surface of the cable 5 to be damaged after the cable 5 is rubbed with the edge of the cable well 6 at a right angle.
The utility model discloses during the use, earlier put into cable shaft 6 with one side protection semi-ring 1 and with 6 side edge gomphosis of cable shaft, then put into cable shaft 6 with opposite side protection semi-ring 1, because two protection semi-rings 1 correspond 2 length L of spacing spacer sleeve between the side connecting plate 1021Equal to the length L of the side edge of the groove of the clamping part 1012In the absence of the spacing spacer 2, there is sufficient space (i.e. L) in the cable well 61Length space) for the other side protection half ring 1 to enter and move to be embedded with the other side edge of the cable well 6, then connecting the connecting plates 102 on the corresponding sides of the two protection half rings 1 with the nuts 4 through the bolts 3, opening and installing the two half distance sleeves of the spacing distance sleeve 2 on the bolts 3 between the two connecting plates 102, then closing the two half distance sleeves of the spacing distance sleeve 2, and fixedly connecting the fixing plates 202 of the two half distance sleeves, also because the length L of the spacing distance sleeve 21Equal to the length L of the side edge of the groove of the clamping part 1012After the limiting spacer 2 is installed, the clamping parts 101 of the two protection half rings 1 can abut against the edge of the cable well 6, and looseness cannot occur. When the cable 5 is pulled down, the cable 5 moves in the cable well 6, and the surface of the cable 5 is in contact with the elastic protection layer 103 on the protection half ring 1, so that the cable is not damaged.
