Description

Technical Field

[0001] The utility model relates to the technical field of cable laying, in particular to an anti-slip structure of a cable trench metal bridge. Background Art

[0002] The cable trench is an underground pipeline used for laying and replacing power or telecommunication cable facilities. It is also a protective structure for the laid cable facilities. It is usually a trough-shaped structure opened on the ground. When laying cables, it is necessary to install a bridge frame on both sides of the trench wall and use a cover plate to block the trench top to facilitate the movement of people. Since the cable trench will become a drainage trough on rainy days, the cover plate is not only washed by rainwater, but also trampled by people walking for a long time, which will eventually cause the cover plate to slide on the trench top and lose the ability to close the cable trench. The existing anti-slip structure seals the cover plate at the trench top, but the sealed cable trench cannot be opened, which greatly affects the work of maintaining the cables. Therefore, a bridge anti-slip structure that does not affect the opening and closing of the cover plate is needed.

[0003] Chinese patent CN216699408U discloses a buckle-type three-way cable bridge, including a straight-through slot plate and a lower-through slot plate. A reserved opening is provided at the bottom of the straight-through slot plate and a lower-through slot plate is provided outside the reserved opening. A cover plate is provided at the top of the straight-through slot plate. The top edge of the straight-through slot plate is buckled and connected with the bottom edge of the cover plate. Both sides of the top of the straight-through slot plate are provided with protrusions. The inner side of the bottom end of the cover plate is provided with a slot, and the protrusions are clamped in the slot. The cover plate of this scheme has an anti-slip structure after buckling, which can effectively prevent the cover plate from sliding horizontally. The connection between the lower slot part and the straight-through slot part of the bridge has a stable structure, which is not easy to deform and is suitable for wide promotion and use.

[0004] There are still several points for improvement in the above scheme: the installation of the cover plate is relatively complicated, which affects the installation efficiency; the sliding cover plate will be stuck in the straight-through groove after being stepped on and walked on by people for a long time, and the cable trench cannot be opened.

DETAILED DESCRIPTION

[0024] In order to further understand the features, technical means, specific objectives and functions of the present invention, the present invention is further described in detail below in conjunction with the accompanying drawings and specific implementation methods.

[0025] See also Figure 1 to Figure 6As shown, an anti-slip structure of a cable trench metal bridge frame includes a bracket 1 and a cover plate 9 installed on the bracket 1 for closing the cable trench, a shell 2 to prevent the cover plate 9 from sliding, an interface 7 for conveniently opening and closing the cover plate 9, and a cross bar 8 for supporting the cover plate 9. The shell 2 includes a first base 3, a buckle 4 for convenient installation and removal of the cover plate 9, a contact plate 5 for strengthening the connection between the buckle 4 and the shell 2, and an engaging hole 6 for preventing the buckle 4 from sliding and displacement. The bracket 1 has two parts respectively installed on the trench walls on both sides of the cable trench, the shell 2 is installed on the top of the bracket 1 on one side, and the interface 7 is installed on the top of the bracket 1 on the other side. One end of the cross bar 8 is rotatably installed on the buckle 4, and the other end is held up by the interface 7. The cover plate 9 is installed on the upper surface of the cross bar 8 and closes the cable trench. The first base 3 is at the bottom of the shell 2 and is installed on the upper surface of the bracket 1. The buckle 4 is embedded in the shell 2, the contact plate 5 is installed on both sides of the buckle 4 and connected to the shell 2, and the engaging hole 6 array is arranged on the surface of the shell 2.

[0026] The anti-slip structure uses the bracket 1 to install the cover plate 9 to control the switch of the cable trench, and supports the cross bar 8 through the shell 2 and the interface 7 to prevent the cover plate 9 from sliding with the bracket 1. The first base 3 is used to strengthen the connection strength between the shell 2 and the bracket 1. The buckle 4 is engaged with the shell 2 to facilitate the installation and removal of the cross bar 8 from the shell 2, thereby ensuring the quick loading and unloading of the cover plate 9. The contact plate 5 provides elasticity for the buckle 4 and strengthens the friction between the buckle 4 and the shell 2 to further prevent the cover plate 9 from sliding. The engaging hole 6 is used to adjust the height of the buckle 4 in the shell 2, thereby adjusting the distance between the cover plate 9 and the bracket 1, and at the same time changing the inclination angle between the cover plate 9 and the ground, so as to facilitate the drainage of rainwater into the cable trench and avoid the accumulation of rainwater on the upper surface of the cover plate 9.

[0027] See also Figure 2 to Figure 4 As shown, the buckle 4 is provided with a groove 41, a first spring 42 and a first telescopic rod 43. The groove 41 is located at the top of the buckle 4 and is connected to one end of the cross bar 8. The first telescopic rod 43 is installed between the buckle 4 and the contact plate 5. The first spring 42 surrounds the outside of the first telescopic rod 43.

[0028] The groove 41 is used to position the installation cross bar 8, and the first spring 42 forms an elastic contact between the buckle 4 and the shell 2. When the buckle 4 is installed in the shell 2, the first spring 42 is compressed and squeezes the contact plate 5, so that the contact plate 5 and the shell 2 are firmly connected. The first telescopic rod 43 is used to prevent the first spring 42 from falling off the buckle 4.

[0029] See also Figure 3 and Figure 4 As shown, the contact plate 5 is provided with a button 51, a barb 52 and a slide groove 53. The barb 52 is installed below the contact side of the contact plate 5 and the shell 2. The slide groove 53 is arranged on the shell 2 and is located on both sides of the barb 52. The button 51 is installed on the contact plate 5 and is located in the slide groove 53.

[0030] The button 51 is used to facilitate squeezing the contact plate 5 from the outside of the shell 2. The hook 52 has the same size as the fitting hole 6. The slide groove 53 is used to limit the movement range of the button 51. When the button 51 is not subjected to force, the first spring 42 squeezes the contact plate 5 so that the hook 52 is embedded in the fitting hole 6, thereby improving the connection strength between the two. When the button 51 is subjected to force, the contact plate 5 squeezes the first spring 42 so that the hook 52 is disengaged from the fitting hole 6, thereby facilitating disassembly.

[0031] See also Figure 1 to Figure 5 As shown, the interface 7 is provided with a second base 71, a positioning platform 72, a movable frame 73 and an interlocking groove 74, the first base 3 is installed at the bottom of the interface 7 and is on the upper surface of the bracket 1, the positioning platform 72 has two respectively installed on both sides of the upper surface of the interface 7, and the interlocking groove 74 is provided on the movable frame 73.

[0032] The second base 71 is used to strengthen the connection strength between the interface 7 and the bracket 1, the positioning platform 72 is used to install the movable frame 73, and the engaging groove 74 is used to support one end of the cross bar 8. Since people walking on the cover plate 9 will squeeze the interface 7 and the shell 2 and cause wear, the elastic contact between the movable frame 73 and the positioning platform 72 is used to reduce the extrusion wear and increase the service life.

[0033] See also Figure 5 As shown, a through slot 721 and a second spring 722 are formed on the positioning platform 72 . The through slot 721 is located in the upper surface of the positioning platform 72 . The second spring 722 is installed in the through slot 721 and contacts the bottom of the movable frame 73 .

[0034] The through slot 721 is used to limit the moving range of the movable frame 73 , and the second spring 722 enables elastic contact to be formed between the movable frame 73 and the positioning platform 72 , which is beneficial to reduce wear.

[0035] See also Figure 2 to Figure 6 As shown, a columnar joint 81, a rotating shaft 82 and a reinforcing plate 83 are provided on the cross bar 8. The columnar joint 81 is installed at one end of the cross bar 8 and is located in the interface 7. The rotating shaft 82 is installed at the other end of the cross bar 8 and is located in the buckle 4. The reinforcing plate 83 is installed on the upper surface of the cross bar 8 and contacts with the cover plate 9.

[0036] The shaft 82 is fixedly installed in the groove 41 on the buckle 4, and the cross bar 8 drives the cover plate 9 to rotate with the shaft 82 as the rotation center. When the cover plate 9 closes the cable trench, the columnar joint 81 contacts the fitting groove 74 on the interface 7, so that the interface 7 and the shell 2 support the cross bar 8 and thus support the cover plate 9. The reinforcing plate 83 is used to increase the contact area between the cross bar 8 and the cover plate 9 to reduce the pressure transmitted from the cover plate 9.

[0037] See also Figure 1 to Figure 6As shown, the cover plate 9 is provided with anti-slip patterns 91 , empty grooves 92 and pull plates 93 . The anti-slip patterns 91 are provided on the upper surface of the cover plate 9 , the empty grooves 92 are provided on one side of the connection between the cover plate 9 and the shell 2 , and the pull plates 93 are installed in the empty grooves 92 .

[0038] The anti-slip grooves 91 are used to increase the friction between people and the upper surface of the cover plate 9 to prevent people from slipping. The empty grooves 92 are used to install the pull plate 93 and remove the obstruction and restriction of the shell 2 when the cover plate 9 rotates. The pull plate 93 is used to maintain the integrity of the cover plate 9 when closing the cable trench.

[0039] See also Figure 6 As shown, a limit plate 931, a second telescopic rod 932 and a pulling groove 933 are provided on the pulling plate 93. The limit plate 931 is installed on one side of the pulling plate 93 and is located inside the cover plate 9. The second telescopic rod 932 is installed on the limit plate 931 and is connected to the cover plate 9. The pulling groove 933 is provided on the upper surface of the pulling plate 93.

[0040] The limit plate 931 always moves inside the cover plate 9 through the second telescopic rod 932 to prevent the pull plate 93 from falling off the cover plate 9. When the cover plate 9 is rotated, the pull plate 93 must be sent back into the cover plate 9 from the empty slot 92 to prevent the pull plate 93 from colliding with the shell 2 and being damaged. When the cover plate 9 is dropped, the pull plate 93 is pulled out again to prevent people from tripping over the empty slot 92.

[0041] The above embodiments only express one or several implementation methods of the present invention, and the description is relatively specific and detailed, but it cannot be understood as limiting the scope of the present invention. It should be pointed out that for ordinary technicians in this field, several modifications and improvements can be made without departing from the concept of the present invention, which all belong to the protection scope of the present invention.
