Detailed Description

The technical solutions in the embodiments of the present invention will be described clearly and completely with reference to the drawings in the embodiments of the present invention, and it is obvious that the described embodiments are only some embodiments of the present invention, not all embodiments. Based on the embodiments in the present invention, all other embodiments obtained by a person skilled in the art without creative efforts all belong to the protection scope of the present invention.

Referring to fig. 1-4, the present invention provides an embodiment:

a roof supports anchor rope tray, including the tray body 100, all spare parts used in this application are products that can be bought directly in the market, its principle and connection mode are the prior art that the technicians in this field is familiar with, therefore will not be described here again, the bottom end of the tray body 100 is fitted with the roof and supported the stock;

the rotation groove 113, the rotation groove 113 is seted up on the top of tray body 100, the inside movable mounting who rotates groove 113 has spherical pivot 110, the top of spherical pivot 110 is provided with top support plate 111, through the setting of above-mentioned structure, can effectively solve the anchor rod tray that discloses in the above-mentioned background art and the installation back of vertically stock can not be better dress in the back of the actual use in the oblique top tunnel, the problem that the intensity that the level shear stress made the stock support descends appears easily after the installation.

The top of top support plate 111 evenly is provided with a plurality of anti-skidding teeth 112, and the top of anti-skidding tooth 112 all is the spine form, and through the setting of above-mentioned structure, in the in-service use anti-skidding tooth 112 can install when tunnel top at top support plate 111, inserts in the soil at tunnel top, strengthens the frictional force between top support plate 111 and the tunnel top.

The material of the spherical rotating shaft 110 is carbon manganese steel, and through the use of the material, the load strength of the spherical rotating shaft 110 can be increased in actual use, so that the service life and the pressure resistance of the spherical rotating shaft 110 are better.

The sliding rod 114 is arranged at the bottom end of the tray body 100, the first sliding block 115 is arranged on the sliding rod 114 in a sliding mode, the first anchor rod mounting block 117 is arranged at the bottom end of the first sliding block 115, the second sliding block 116 is arranged on the sliding rod 114 in a sliding mode, the second anchor rod mounting block 118 is arranged at the bottom end of the second sliding block 116, two threaded rods 120 are arranged in front of and behind the second anchor rod mounting block 118 in a penetrating mode, through the arrangement of the structure, the first sliding block 115 and the second sliding block 116 can slide on the sliding rod 114 in actual use, so that the first anchor rod mounting block 117 and the second anchor rod mounting block 118 can adapt to and mount anchor rods with different diameters, meanwhile, after the anchor rods are mounted through the structure, the movement of the anchor rods can be limited, and connection between the anchor rods and the tray body 100 is strengthened.

One side fixed mounting of second stock installation piece 118 has two grooving 119, all fixed mounting have the connection rope 121 on the threaded rod 120, connect the rope 121 all to be connected with grooving 119, through the setting of above-mentioned structure, can avoid threaded rod 120 to lose in the in-service use.

The bottom end of the top support plate 111 is provided with the arch-shaped reinforcing block 122, the arch-shaped reinforcing block 122 is in an arc arch shape, the inside of the arch-shaped reinforcing block 122 is solid, and through the arrangement of the structure, in the practical use, the arch-shaped reinforcing block 122 is a new arch-shaped reinforcing block, so that the overall compressive strength of the spherical rotating shaft 110 can be enhanced.

The working principle is as follows: in practical use, when the tray body 100 needs to be installed on a pitched roof roadway, the top support plate 111 is installed on the pitched roof of the roadway through the fixing rod, the tray body 100 is rotated afterwards, the tray body 100 is made to be horizontal to the ground, then the anchor cable is placed at the bottom end of the sliding rod 114, the top end of the anchor cable is made to be tightly attached to the bottom end of the sliding rod 114, at this time, the first sliding block 115 and the second sliding block 116 slide on the sliding rod 114, the anchor cable is wrapped by the first anchor rod installation block 117 and the second anchor rod installation block 118, it needs to be noted that the anchor rod does not penetrate through the spherical rotating shaft 110, at this time, the threaded rod 120 on the second anchor rod installation block 118 is fixed on the first anchor rod installation block 117, the position of the anchor cable can be limited, after the installation, the spherical rotating shaft 110 and the top support plate 111 are stressed, because the structure of the spherical rotating shaft 110 is a spherical hinge structure, and the material of the spherical rotating shaft 110 is carbon manganese steel, the structural strength of the spherical rotating shaft 110 is large and uniform, the deformation at a certain position is not easy to be provided for the arched reinforcement block 122, and the service life of the tray is longer.

It will be evident to those skilled in the art that the invention is not limited to the details of the foregoing illustrative embodiments, and that the present invention may be embodied in other specific forms without departing from the spirit or essential attributes thereof. The present embodiments are therefore to be considered in all respects as illustrative and not restrictive, the scope of the invention being indicated by the appended claims rather than by the foregoing description, and all changes which come within the meaning and range of equivalency of the claims are therefore intended to be embraced therein. Any reference sign in a claim should not be construed as limiting the claim concerned.
