DETAILED DESCRIPTION

[0027] The following will be combined with 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 of 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.

[0028] like Figure 1-Figure 6 As shown, a cable trough for laying underground pipelines includes a trough plate 1, two slide grooves 2 are provided on the bottom surface of the trough plate 1, a plurality of slide plates 3 are installed in the two slide grooves 2, a mounting groove 4 is provided on the upper surface of each slide plate 3, two mounting blocks 5 are slidably arranged in each mounting groove 4, an arc-shaped clamping plate 6 is fixedly installed on the upper surface of each mounting block 5, and the clamping surfaces of adjacent arc-shaped clamping plates 6 are arranged opposite to each other;

[0029] A bidirectional screw rod 7 is rotatably mounted between the inner walls of each mounting groove 4, and adjacent mounting blocks 5 are respectively threadedly arranged on both sides of the bidirectional screw rod 7;

[0030] A protective cover 22 is fixedly mounted on the upper surface of the slot plate 1 by means of fastening bolts 21. The slot plate 1 and the protective cover 22 cooperate to effectively protect the cable.

[0031] A first bevel gear 8 is sleeved on one side of the rod body of each bidirectional screw rod 7;

[0032] A horizontal plate 9 is fixedly mounted on one side of the upper surface of each slide plate 3 near the corresponding first bevel gear 8, and a rotating rod 10 is rotatably mounted on the lower surface of each horizontal plate 9. A second bevel gear 11 is sleeved on one side of the shaft of each rotating rod 10, and each second bevel gear 11 is respectively meshed with the corresponding first bevel gear 8;

[0033] The upper end of each rotating rod 10 passes through the corresponding transverse plate 9 and is fixedly mounted with a rotating wheel 12 .

[0034] The staff passes each cable through the adjacent arc-shaped clamping plates 6 respectively, and then rotates the rotating wheel 12 to drive the rotating rod 10 to rotate. Under the meshing action of the first bevel gear 8 and the second bevel gear 11, the bidirectional screw rod 7 rotates, and the rotating bidirectional screw rod 7 drives the adjacent arc-shaped clamping plates 6 to move relative to each other by screwing in the thread, so that the arc-shaped clamping plates 6 can clamp and limit cables of different diameters, thereby being able to meet the needs of various cables and reducing costs.

[0035] In another embodiment of the present invention, each slide plate 3 is slidably disposed in the corresponding slide groove 2 .

[0036] Each slide plate 3 has a moving groove 13 on both sides of its upper surface, and two moving blocks 14 are slidably arranged in each moving groove 13, and a push plate 15 is fixedly installed on the upper surface of each moving block 14;

[0037] Two moving rods 16 are fixedly installed between the two sides of the inner wall of each moving groove 13, and the adjacent moving blocks 14 are slidably arranged on the two sides of the corresponding moving rods 16, and the side of the adjacent moving blocks 14 away from each other is fixedly installed with a top plate 17;

[0038] Limiting grooves 18 are provided on both side surfaces of the inner walls of the two slide grooves 2 .

[0039] By sliding the slide plate 3 in the slide groove 2, the staff can move the arc clamping plate 6 along the slide groove 2, which is convenient for the staff to adjust the position of the arc clamping plate 6 according to the installation position of the cable. After the staff moves the push plate 15 to make the top plate 17 disengage from the limit groove 18, the staff can move the slide plate 3 to the outside of the slide groove 2, or install the slide plate 3 into the slide groove 2 and then move the push plate 15 in the opposite direction to make the top plate 17 move to the inside of the limit groove 18, which is convenient for the staff to adjust the number of arc clamping plates 6 according to the number of installed cables.

[0040] In another embodiment of the present invention, a rubber frame 19 is fixedly installed in each limiting groove 18 .

[0041] By setting the rubber frame 19, the top plate 17 is squeezed after entering the limiting groove 18, so that the rubber frame 19 is deformed, and the inner wall thereof is fitted with the top plate 17, so that the position of the arc clamping plate 6 is fixed, thereby preventing the cable from being deviated during operation, causing the internal material thereof to be squeezed and damaged, thereby causing damage to the cable.

[0042] In another embodiment of the present invention, a spring 20 is sleeved on the middle part of the shaft of each moving rod 16 .

[0043] By providing the spring 20 , the moving block 14 is not easy to move under the elastic force of the spring 20 , which further avoids the possibility of the cable being deviated during operation.

[0044] The working principle of a cable trough for laying underground pipelines:

[0045] When in use, the staff passes each cable through the adjacent arc-shaped clamps 6 respectively, and then rotates the rotating wheel 12 to drive the rotating rod 10 to rotate. Under the meshing action of the first bevel gear 8 and the second bevel gear 11, the bidirectional screw rod 7 rotates, and the rotating bidirectional screw rod 7 drives the adjacent arc-shaped clamps 6 to move relative to each other by screwing in the thread, so that the arc-shaped clamps 6 can clamp and limit cables of different diameters, thereby being able to meet the needs of various cables and reducing costs.

[0046] Obviously, the above embodiments of the present invention are merely examples for clearly illustrating the present invention, and are not limitations on the implementation methods of the present invention. For ordinary technicians in the relevant field, other different forms of changes or modifications can be made on the basis of the above description. It is impossible to list all the implementation methods here. All obvious changes or modifications derived from the technical solution of the present invention are still within the protection scope of the present invention.
