Description

Technical Field

[0001] The utility model relates to the technical field of cable protection tubes, in particular to a cable protection tube with strong pressure resistance. Background Art

[0002] In the use of laying cables in coal mines, the traditional cable laying method usually adopts direct exposed laying. The consequence of exposed laying is that it is easy to cause safety accidents. It is not convenient to place in the narrow space of coal mines, and the cable itself is also easily damaged.

[0003] China's authorization announcement number CN210246276U discloses a cable laying for coal mines, which includes a buffer belt and a protective device. The protective device is connected to one side of the buffer belt by embedding. The protective device includes a cable and a double-strand wire trough. The double-strand wire trough is connected to the inner surface of the cable by embedding. The double-strand wire trough includes a protective cover, a shock-absorbing lock, and a wire trough bottom plate. The protective cover is connected to the upper surface of the wire trough bottom plate by snapping, and the shock-absorbing lock is connected to the upper surface of one end of the wire trough bottom plate by embedding. The beneficial effects of the utility model are: the protective device used for laying cables in coal mines can be installed simultaneously with the laying of cables, solving the safety problem of cables in coal mines. The protective device can bear a large pressure, further protecting the safety of the cable itself. The design of the protective cover and the shock-absorbing lock reduces the cost of installation and is very reliable to use. .

[0004] However, the device still has the following defects when in use: although the protective cover plays a role in absorbing pressure, since there is a groove for placing cables on the upper surface of the bottom plate of the cable trough, when a heavier vehicle passes over the device, the cable placement groove will bend and deform into the groove for placing cables after being stressed, and cannot withstand pressure, which can easily cause the protective cover to get stuck and unable to rebound, or even cause the protective cover to deform and detach from the bottom plate of the cable trough, exposing the cable. In response to the above defects: To this end, we propose a cable protection tube with strong pressure resistance. Utility Model Content

[0005] The utility model aims to provide a cable protection tube with strong pressure resistance to solve the problems raised in the above background technology.

[0006] In order to achieve the above purpose, the utility model adopts the following technical solutions:

[0007] A cable protection tube with strong pressure resistance comprises a protective cover, wherein a cable layered placement structure is arranged inside the protective cover, and self-assembly structures are arranged at both ends of the protective cover, the protective cover is composed of a base and an arc-shaped protective plate arranged above the base and engageable with the base, and a pressure-resistant component is arranged between the arc-shaped protective plate and the base, and the pressure-resistant component is composed of a pressure-resistant block and a honeycomb block.

[0008] Preferably, the lower surface of the anti-compression block is fixedly connected to the upper surface of the base, and the inner annular surface of the arc-shaped protective plate is provided with a slot for inserting the anti-compression block.

[0009] Preferably, the number of the anti-compression blocks and the number of the slots are both three, the three anti-compression blocks are equidistantly arranged on the upper surface of the base, and the three slots are equidistantly arranged on the inner annular surface of the arc-shaped protective plate.

[0010] Preferably, an arc-shaped groove is provided on the front side of the arc-shaped protective plate, and the honeycomb block is fixedly mounted on the inner wall of the arc-shaped groove.

[0011] Preferably, the cable layered placement structure includes an oblique support, the shape of the oblique support is set to be X-shaped, the number of the oblique supports is two, and the two oblique supports are respectively fixedly installed between two adjacent anti-compression blocks.

[0012] Preferably, the upper surfaces of the base and the arc-shaped protective plate are provided with mounting holes for external bolts to pass through.

[0013] Compared with the prior art, the utility model has the following advantages:

[0014] 1. The utility model provides a pressure-resistant component and an arc-shaped protective plate. When the protective cover is fixed to the ground, the base will be fixed together with the arc-shaped protective plate. When a vehicle passes over the arc-shaped protective plate, the arc-shaped protective plate has greater pressure resistance because it is arranged in an arc shape. At the same time, the honeycomb block will disperse the pressure to the entire arc-shaped protective plate. The pressure on the arc-shaped protective plate will be shared by the pressure-resistant block to the base. The base will transmit the pressure to the ground, thereby avoiding deformation and breaking of the arc-shaped protective plate, and effectively protecting the cables in the protective cover.

[0015] 2. The utility model sets an oblique support in an X-shape, so that cables can be placed in layers inside the oblique support to avoid cables piling up and affecting subsequent maintenance. At the same time, the oblique support can pull the anti-compression block, thereby improving the strength of the anti-compression block.

[0016] 3. The utility model sets a self-assembly structure to clamp the arc-shaped card plate on the protective cover into the arc-shaped card groove on another protective cover, so that the two protective covers can be fixed as a whole, so that the protective cover can be laid on the road surface according to the length of the road surface. On the one hand, fixing multiple protective covers as a whole can improve the overall strength, and on the other hand, it can reduce the connection gap between the two protective covers to prevent foreign matter from falling into the protective cover.

[0021] The technical solutions in the embodiments of the present invention will be described clearly and completely below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all of the embodiments.

[0022] In the description of the present invention, it should be understood that the terms "upper", "lower", "front", "back", "left", "right", "top", "bottom", "inside", "outside", etc., indicating directions or positional relationships, are based on the directions or positional relationships shown in the accompanying drawings, and are only for the convenience of describing the present invention and simplifying the description, rather than indicating or implying that the device or element referred to must have a specific direction, be constructed and operated in a specific direction, and therefore should not be understood as a limitation on the present invention.

[0023] Reference Figure 1-3 A cable protection tube with strong pressure resistance includes a protective cover, which is composed of a base 1 and an arc-shaped protective plate 2 arranged above the base 1 and can be engaged with the base 1. The upper surfaces of the base 1 and the arc-shaped protective plate 2 are both provided with mounting holes 6 for external bolts to pass through. After the arc-shaped protective plate 2 is placed on the base 1, the external bolts are then passed through the mounting holes 6, so that the arc-shaped protective plate 2 and the base 1 can be fixed as a whole. The external bolts are expansion bolts, and the embedded parts of the expansion bolts are embedded in the ground.

[0024] A pressure-resistant component is arranged between the arc-shaped protective plate 2 and the base 1, and the pressure-resistant component is composed of a pressure-resistant block 3 and a honeycomb block 4. An arc-shaped groove is provided on the front of the arc-shaped protective plate 2, and the honeycomb block 4 is fixedly installed on the inner wall of the arc-shaped groove. The lower surface of the pressure-resistant block 3 is fixedly connected to the upper surface of the base 1, and a slot for inserting the pressure-resistant block 3 is provided on the inner ring surface of the arc-shaped protective plate 2. The number of the pressure-resistant blocks 3 and the slots are both three. The three pressure-resistant blocks 3 are equidistantly arranged on the upper surface of the base 1, and the three slots are equidistantly arranged on the inner ring surface of the arc-shaped protective plate 2.

[0025] When the arc-shaped protective plate 2 is fixed to the base 1 as a whole, the anti-compression block 3 will be inserted into the slot. When the vehicle passes over the arc-shaped protective plate 2, since the arc-shaped protective plate 2 is arranged to be arc-shaped, it has greater pressure resistance. At the same time, the honeycomb block 4 will disperse the pressure to the entire arc-shaped protective plate 2. The pressure on the arc-shaped protective plate 2 will be shared by the base 1 through the anti-compression block 3. The base 1 will transmit the pressure to the ground, thereby avoiding deformation and breaking of the arc-shaped protective plate 2, and thus effectively protecting the cables in the protective cover.

[0026] A cable layered placement structure is provided inside the protective cover, and the cable layered placement structure includes an inclined support 5. The shape of the inclined support 5 is set to be X-shaped. There are two inclined supports 5, and the two inclined supports 5 are respectively fixedly installed between two adjacent anti-compression blocks 3. When the arc-shaped protective plate 2 is fixed to the base 1 as a whole, the cables can be placed in layers inside the inclined support 5 to avoid the cables from piling up and affecting subsequent maintenance. At the same time, the inclined support 5 can pull the anti-compression block 3, thereby improving the strength of the anti-compression block 3.

[0027] Self-assembly structures are provided at both ends of the protective cover, and the self-assembly structure includes an arc-shaped clamping plate 7 fixedly installed on the back of the arc-shaped protective plate 2, and the outer ring surface of the arc-shaped protective plate 2 is provided with an arc-shaped clamping groove 8 adapted to the arc-shaped clamping plate 7. The arc-shaped clamping plate 7 on the protective cover is clamped in the arc-shaped clamping groove 8 on another protective cover, so that the two protective covers can be fixed as one, so that multiple protective covers can be laid on the road surface according to the length of the road surface. On the one hand, fixing multiple protective covers as one can improve the overall strength, and on the other hand, it can reduce the connection gap between the two protective covers to prevent foreign objects from falling into the protective cover.

[0028] The above is only a preferred specific implementation manner of the present invention, but the protection scope of the present invention is not limited thereto. Any technician familiar with the technical field can make equivalent substitutions or changes within the technical scope disclosed by the present invention according to the technical solution and inventive concept of the present invention, which should be covered by the protection scope of the present invention.
