[0020] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.
[0021] This utility model provides, for example Figure 1-3The steel frame support beam shown includes a crossbeam body 1, which is used to support and install tunnel pipes. Grooves 2 are provided on both sides of the crossbeam body 1 so that the crossbeam body 1 maintains an I-shaped configuration.
[0022] Both ends of the main body 1 of the crossbeam are provided with installation mechanisms 3, which are used to fix the main body 1 of the crossbeam and facilitate the installation and disassembly of the main body 1 of the crossbeam.
[0023] The installation mechanism 3 includes a steel frame plate 31. The outer wall of the other side of the steel frame plate 31 is attached to the rock wall of the tunnel for installing the main body of the crossbeam 1. Two steel frame plates 31 are respectively set at both ends of the main body of the crossbeam 1. One end of the main body of the crossbeam 1 is attached to the outer wall of one side of the steel frame plate 31. A support plate 32 is fixedly connected to one side of the steel frame plate 31. The support plate 32 is used to support and install one end of the main body of the crossbeam 1. The upper surface of the support plate 32 is attached to the lower surface of one end of the main body of the crossbeam 1. The steel frame plate 31 is equidistantly slidably interlocked in a rectangular array. Multiple anchor bolts 33 are connected. By opening fixing holes in the rock wall of the tunnel to install the anchor bolts 33, the other end of the anchor bolt 33 is fixedly installed in the inner cavity of the fixing hole. The steel frame plate 31 is fixedly installed on the side wall of the tunnel by multiple anchor bolts 33 to ensure the stability of the steel frame plate 31. One end of the anchor bolt 33 is threadedly connected to a nut 34. The nut 34 is at one end of the anchor bolt 33. By rotating the nut 34, it is threadedly connected to one end of the anchor bolt 33. One end of the nut 34 presses and fixes the elastic washer 5 and one side of the steel frame plate 31.
[0024] Positioning mechanisms 4 are provided at both ends of the main body 1 of the crossbeam, which are used to facilitate the quick and easy installation of the main body 1 of the crossbeam and to make it easy to fix the main body 1 of the crossbeam to the steel frame plate 31.
[0025] The positioning mechanism 4 includes a mounting groove 41, which is located at the middle of the bottom of one end of the crossbeam body 1. The mounting groove 41 is used to connect the mounting block 42. The mounting block 42 is fixedly connected to the middle of one side of the steel frame plate 31. The mounting block 42 is slidably inserted into the inner cavity of the mounting groove 41. The outer wall of the mounting block 42 is in contact with the inner wall of the mounting groove 41. By moving the crossbeam body 1 between the two steel frame plates 31, the mounting groove 41 and the mounting block 42 are aligned. Then, the crossbeam body 1 is moved downward to slide the mounting block 42 into the inner cavity of the mounting groove 41, ensuring that the fixing rod 43 is aligned with the mounting hole and the positioning rod 45 is aligned with the through hole.
[0026] A fixing rod 43 is fixedly connected to the upper surface of the mounting block 42. The top of the outer wall of the fixing rod 43 is provided with an external thread. The top of the inner wall of the mounting groove 41 is provided with a mounting hole. The inner cavity of the mounting hole is slidably inserted into the fixing rod 43. When the mounting block 42 is slidably inserted into the inner cavity of the mounting groove 41, it drives the fixing rod 43 to slide into the inner cavity of the mounting hole. The top thread of the fixing rod 43 is connected to a nut 44. By rotating the top of the fixing rod 43 to tighten the nut 44, the bottom end of the nut 44 presses and fixes the upper surface of one end of the crossbeam body 1, thus fixing one end of the crossbeam body 1 to the steel frame plate 31.
[0027] Positioning rods 45 are fixedly connected to the middle of the lower surface of both ends of the crossbeam body 1. The positioning rods 45 move together with the crossbeam body 1. The support plate 32 has through holes. The inner cavity of the through holes is slidably inserted into the positioning rods 45. As one end of the crossbeam body 1 moves, the positioning rods 45 slide into the inner cavity of the through holes, connecting one end of the crossbeam body 1 to the support plate 32, thus limiting and fixing one end of the crossbeam body 1.
[0028] An elastic washer 5 is provided on one side of nut 34. The middle part of the elastic washer 5 is slidably inserted into one end of anchor rod 33. One end of nut 34 is in contact with one side of elastic washer 5. By rotating and tightening nut 34, one end of nut 34 is squeezed and deformed against elastic washer 5, which improves the stability of nut 34 and prevents nut 34 from loosening.
[0029] A reinforcing block 6 is fixedly connected to the bottom of one side of the outer wall of the steel frame plate 31. The reinforcing block 6 is inclined and its top is fixedly connected to the lower surface of the support plate 32. The reinforcing block 6 is used to connect the support plate 32 and the steel frame plate 31 to improve the stability of the support plate 32.
[0030] Finally, it should be noted that the above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
