Description

Technical Field

[0001] The utility model relates to the technical field of support equipment, in particular to a T-shaped steel belt fastening anchor with convenient installation. Background Technique

[0002] The T-shaped steel belt, also known as the roof steel belt, is a steel product cold-pressed from a strong alloy plate. Its shape is similar to the letter "T", and it has the characteristics of high strength and strong integrity. The T-shaped steel belt is widely used in the roadway working face cutting eye, chamber and other areas of the mine roadway support, especially suitable for dealing with unstable surrounding rock.

[0003] When the T-shaped steel belt is used as a support, it also needs to be combined with various fastening elements such as bolts and anchor cables to form a powerful support system. Specifically, when in use, the bolt or anchor cable passes through the hole of the T-shaped steel belt and is fixed in the bedrock or concrete through fastening devices (such as nuts, gaskets, etc.), so as to realize the effective support and fixation of the structure. Although the use of fastening devices such as nuts to connect the bolt and the T-shaped steel belt does ensure the firmness and stability of the installation, when facing the installation operation of multiple groups of bolts and T-shaped steel belts, the staff has to frequently use tools such as wrenches to perform cumbersome and repetitive nut tightening operations, which not only takes a long time, but also greatly tests the physical strength and endurance of the operators. In addition, the specific installation angle and other limiting conditions of the T-shaped steel belt further increase the complexity and difficulty of the operation, making the entire installation process time-consuming and laborious. In view of this, we propose a T-shaped steel belt fastening anchor with convenient installation. Content of the Utility Model

[0026] Next, the technical solutions in the embodiments of the present utility model will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present utility model. Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all the embodiments. All other embodiments obtained by those of ordinary skill in the art based on the embodiments of the present utility model without creative efforts shall fall within the protection scope of the present utility model.

[0027] This embodiment provides a technical solution:

[0028] Please refer to Figures 1-6As shown in the figure, a conveniently installed T-shaped steel belt fastening anchor includes a T-shaped steel belt 1. A plurality of connecting grooves 10 are formed on the front end face of the T-shaped steel belt 1. A support 11 is fixed to one side of each connecting groove 10, and a fixing hole 111 is formed in each support 11; fixing frames 12 are installed between adjacent supports 11 on the front end face of the T-shaped steel belt 1. A cavity 121 is formed at the center of the rear end face of the fixing frame 12, and sliding cavities 122 are formed on both the left and right sides of the cavity 121; two symmetrically arranged secondary bevel gears 13 are rotatably installed in the cavity 121, and a primary bevel gear 14 is meshed at the front side between the two secondary bevel gears 13; a lead screw 15 is coaxially key-connected to each secondary bevel gear 13, and the lead screw 15 penetrates into the sliding cavity 122; a sliding seat 16 is slidably installed in each sliding cavity 122. A strip-shaped groove 162 is formed in the sliding seat 16, and the end of the lead screw 15 penetrates into the strip-shaped groove 162 and is threadedly connected to the sliding seat 16; fixing rods 17 are fixed to the two opposite ends of the two sliding seats 16, and the ends of the fixing rods 17 are inserted into the corresponding fixing holes 111; anchor rods 2 are provided at the rear side of the T-shaped steel belt 1 directly behind the connecting grooves 10. Connecting blocks 20 are fixed to the front ends of the anchor rods 2. The connecting blocks 20 pass through the connecting grooves 10. A connecting hole 201 is formed in the connecting block 20, and the fixing rod 17 passes through the connecting hole 201.

[0029] In this embodiment, guiding grooves 123 are formed on both side walls of the sliding cavity 122. Guiding strips 161 are fixed to the outer walls on both sides of the sliding seat 16, and the guiding strips 161 are slidably connected to the guiding grooves 123. This design realizes the stable sliding of the sliding seat 16 in the sliding cavity 122, effectively reducing the shaking and deviation of the sliding seat 16 during movement, and improving the stability and precision of the overall structure.

[0030] In this embodiment, a screwing block 19 is rotatably installed at the center of the front end face of the fixing frame 12. The cross-sectional shape of the screwing block 19 is a regular hexagon, and a connecting shaft is coaxially key-connected between the screwing block 19 and the primary bevel gear 14. This design enables the screwing block 19 to efficiently transmit torque and drive the primary bevel gear 14 to rotate, improving the convenience of installation. The regular hexagon design facilitates rotation by a wrench or the like.

[0031] In this embodiment, the sliding seat 16 and the fixing rod 17 are of an integrally formed structure, and the cross-sectional shape of the sliding seat 16 is a rectangle. The integral formation enhances the strength and stiffness of the sliding seat 16 and the fixing rod 17. At the same time, the design of the sliding seat 16 with a rectangular cross-section is beneficial to bearing a greater load and improving its load-bearing capacity.

[0032] In this embodiment, a plurality of reinforcing blocks 18 are fixed at the connection between the fixing frame 12 and the T-shaped steel strip 1, and the cross-sectional shape of the reinforcing blocks 18 is triangular. The plurality of triangular reinforcing blocks 18 effectively disperse the stress concentration at the connection between the fixing frame 12 and the T-shaped steel strip 1, enhance the strength and stability of the connection structure. This design can resist greater tensile and shear forces, and extend the service life of the equipment.

[0033] In this embodiment, limiting edges 21 are installed at the top edges of the connection blocks 20, and the anchor bolts 2, the connection blocks 20 and the limiting edges 21 are integrally formed structures. The setting of the limiting edges 21 plays a role in limiting the connection blocks 20, which is beneficial for the fixing rods 17 to be inserted into the connection holes 201 accurately. At the same time, the integrally formed structure increases the connection strength of the anchor bolts 2, the connection blocks 20 and the limiting edges 21, and ensures the connection stability of the anchor bolts 2, the connection blocks 20 and the limiting edges 21.

[0034] In this embodiment, the T-shaped steel strip 1 is tightly welded to the fixing frame 12, and both the T-shaped steel strip 1 and the fixing frame 12 are formed by hot rolling in one step. The tight welding method ensures the tightness and reliability of the connection between the T-shaped steel strip 1 and the fixing frame 12, while the hot rolling in one step process increases the strength, plasticity and toughness of the T-shaped steel strip 1 and the fixing frame 12, enabling the T-shaped steel strip 1 and the fixing frame 12 to exert greater bending and shear resistance when bearing loads.

[0035] It can be understood that the thread winding directions of the two lead screws 15 in this embodiment are opposite. When the lead screws 15 rotate, they can drive the two sliding seats 16 on both sides to move synchronously relative to each other, which is beneficial for the fixing rods 17 on both sides to fix the connection blocks 20 on both sides at the same time.

[0036] It should be added that the size of the connection groove 10 in this embodiment is adapted to the size of the connection block 20. After the connection block 20 passes through the connection groove 10, the connection block 20 will not shake at the connection groove 10, thus ensuring the installation stability of the T-shaped steel strip 1.

[0037] During specific use, the user first drives multiple anchor bolts 2 into the bedrock at a fixed spacing. Subsequently, the user inserts the connection groove 10 on the T-shaped steel strip 1 into the connection block 20. Then, the user rotates the screwing block 19, and the screwing block 19 drives the main bevel gear 14 to rotate. Since the main bevel gear 14 meshes with the auxiliary bevel gears 13 on both sides, the auxiliary bevel gears 13 on both sides rotate synchronously and drive the lead screw 15 to rotate. At this time, the sliding seats 16 on both sides move relatively synchronously, and the sliding seats 16 drive the fixing rods 17 on both sides to move towards both sides at the same time. The fixing rods 17 pass through the connection holes 201 and the fixing holes 111 at the same time. When the end of the sliding seat 16 abuts against the connection block 20, the user stops rotating the screwing block 19. Repeat the above steps and rotate the screwing block 19 on the other side to connect and fix the T-shaped steel strip 1 to the multiple anchor bolts 2, and the installation of the T-shaped steel strip 1 is completed.

[0038] The above shows and describes the basic principles, main features and advantages of the present invention. Those skilled in the art should understand that the present invention is not limited by the above embodiments. The above embodiments and descriptions in the specification are only preferred examples of the present invention and are not used to limit the present invention.
