Description

Technical Field

[0001] This invention relates to the field of grounding angle steel construction technology, specifically to a construction device for grounding angle steel of roadbed contact network foundation. Background Technology

[0002] According to the integrated grounding system network of railway engineering, the bottom of the contact network foundation piles in domestic roadbeds is generally equipped with an integrated grounding system of grounding angle steel. The angle steel needs to be driven in during the construction of the contact network foundation piles. In traditional construction methods, the grounding angle steel at the bottom of the contact network foundation piles is driven manually or by large machinery (such as using an excavator arm to forcibly drive it). Due to the difference in the bearing capacity of the foundation, the position, depth, angle, and integrity of the grounding angle steel itself cannot be guaranteed when driving it manually, which reduces the construction efficiency of the grounding angle steel and leads to unsatisfactory construction quality. When using large machinery, the grounding angle steel is often easily damaged and bent, losing its design function. Moreover, the construction of large machinery requires a lot of investment, and the relocation of machinery is inconvenient, which greatly affects the grounding effect and shortens the service life of the grounding angle steel.

[0003] As can be seen from the above, the existing methods of using manual labor and large machinery reduce the construction efficiency and effectiveness of grounding angle steel.

[0004] Therefore, there is a need to provide a construction device for the grounding angle steel of the roadbed contact network foundation, which aims to solve the above problems. Summary of the Invention

[0042] Example 2

[0043] like Figure 1 , Figure 2 , Figure 5 , Figure 6 , Figure 7 , Figure 8 and Figure 9As shown, in a preferred embodiment of the present invention, the reciprocating assembly 9 includes a fixed frame 901, a first spring 902, a movable frame 903, a fixed seat 904, a fixed plate 905, a guide rod 906, a motor 907, a rotating disk 908, and a protruding rod 909. The fixed frame 901 is fixedly connected to the top of the telescopic top frame 4. One end of the first spring 902 is fixedly connected to the outer surface of the fixed frame 901, and the other end of the first spring 902 is fixedly connected to the inside of the movable frame 903. The movable frame 903 is laterally movably connected to the fixed frame 901. The fixed seat 904 is fixedly connected to the middle of the movable frame 903 by bolts. The fixed plate 905 is fixedly connected to the top of the fixed base 904. Guide rods 906 for guiding are provided on both sides of the fixed plate 905. The motor 907 is fixedly connected to the outside of the fixed plate 905 and is electrically connected to the external power supply of the equipment. The rotating disk 908 is fixedly connected to the inside of the output end of the motor 907 and rotates on the inside of the fixed plate 905. The protruding rod 909 is fixedly connected to the inner edge of the rotating disk 908. The diameter of the rotation arc of the protruding rod 909 is the same as the length of the guide rod 906. The rotation of the protruding rod 909 can drive the reciprocating frame 1001 to move up and down.

[0044] The auxiliary component 10 includes a reciprocating frame 1001, a connecting rod 1002, an auxiliary cylinder 1003, a limiting groove 1004, a second spring 1005, and a limiting block 1006. The two ends of the reciprocating frame 1001 are vertically movably connected to the guide rod 906. A slot adapted to a protruding rod 909 is provided in the middle of the reciprocating frame 1001. The rotation of the protruding rod 909 drives the reciprocating frame 1001 to move up and down. The protruding rod 909 is movably connected inside the reciprocating frame 1001. The connecting rod 1002 is hinged to the reciprocating frame 1001. Inside 001, the inner end of the connecting rod 1002 is hinged to the outer side of the auxiliary cylinder 1003. The limiting groove 1004 is opened inside the auxiliary cylinder 1003. One end of the second spring 1005 is fixedly connected to the inside of the limiting groove 1004. The other end of the second spring 1005 is fixedly connected to the outer wall of the limiting block 1006. The top of the limiting block 1006 is hinged to the inside of the limiting groove 1004. The limiting block 1006 is set to a downward tilt of 45 degrees, which can limit the hollow tube 1101.

[0045] Example 3

[0046] like Figures 1 to 7 As shown, in a preferred embodiment of the present invention, the guide assembly 8 includes a folding frame 801 and a guide ring 802. The outer end of the folding frame 801 is hinged to the inside of the telescopic top frame 4, and the inner end of the folding frame 801 is hinged to the outer wall of the guide ring 802.

[0047] The hammering assembly 11 includes a hollow tube 1101, a hammer head 1102, and a buffer pad 1103. The hollow tube 1101 is movably connected inside the auxiliary cylinder 1003. A threaded joint structure is provided at the end of the hollow tube 1101. After the hollow tube 1101 is connected by bolts, the hammering length of the hollow tube 1101 can be extended. The hammer head 1102 is fixedly connected to the bottom of the hollow tube 1101. The hammer head 1102 is made of hollow high-density cast steel. The buffer pad 1103 is fixedly connected to the bottom of the hammer head 1102. The buffer pad 1103 is made of rubber and plays a buffering role to prevent damage to the grounding angle steel.

[0048] Working principle: In the initial state, both the telescopic base frame 1 and the telescopic top frame 4 are in the retracted state, so that the protective net 7 is in the folded state, the folded ground anchor 3 and the folded handle 6 are in the retracted state, the telescopic top frame 4 drives the fixed frame 901 to be in the innermost position relative to the movable frame 903, the first spring 902 is in the relaxed extended state, the connecting rod 1002 is in the retracted state in the inward direction, and at the same time the second spring 1005 is in the relaxed extended state, the second spring 1005 causes the limiting block 1006 to be in the outward tilted state.

[0049] During operation, the ground is leveled, holes are drilled at the locations where grounding angle steel needs to be installed, and then the device is unfolded so that the telescopic base frame 1 and telescopic top frame 4 extend. The protective net 7 unfolds under the extension of the telescopic base frame 1 and telescopic top frame 4, thus protecting the interior of the equipment and preventing the risk of debris from escaping during the installation of the grounding angle steel, thereby reducing the risk of accidents. It also prevents debris or other objects outside the equipment from affecting the installation of the grounding angle steel, improving safety during construction. The extension of the telescopic base frame 1 and telescopic top frame 4 causes the folding frame 801 to unfold, driving the guide ring 802 to move outwards, and the telescopic top frame 4 drives the fixed... The fixed frame 901 moves outward inside the movable frame 903 and compresses the first spring 902, unfolding the folded ground anchor 3 to a horizontal position with the ground. At the same time, the device is leveled by observing the horizontal positioning instrument 5 to prevent tilting when driving the grounding angle steel, thereby improving the accuracy of driving the grounding angle steel into the correct position and improving the accuracy of driving the grounding angle steel. At this time, the ground anchor nail is driven onto the folded ground anchor 3, and the device is fixed by the ground anchor nail and the folded ground anchor 3. The grounding angle steel is placed in the drilled hole, and then the hollow tube 1101 passes through the auxiliary cylinder 1003 and abuts against the top of the abutting angle steel through the guide ring 802.

[0050] Because motor 907 is electrically connected to the external power supply of the equipment, after motor 907 is powered on, it drives rotating disk 908 to rotate. Rotating disk 908 drives reciprocating frame 1001 to move up and down on guide rod 906 via protruding rod 909. Reciprocating frame 1001 drives auxiliary cylinder 1003 to move up and down via connecting rod 1002. When auxiliary cylinder 1003 moves downward, the limiting block 1006 moves downward relative to hollow tube 1101 under the limiting action of limiting groove 1004. During the downward movement of hollow tube 1101, it can maintain stability through guide ring 802, ensuring the stability of buffer pad 1103 when striking grounding angle steel, preventing skew during the installation of grounding angle steel, and improving the accuracy of grounding angle steel installation. When hollow tube 1101 moves downward, it drives buffer pad 1103 to strike grounding angle steel through hammer head 1102, thereby achieving... To achieve the effect of automatically installing grounding angle steel, the problem of unsatisfactory angle and depth when manually installing grounding angle steel is reduced, improving the construction efficiency of grounding angle steel, and ensuring the quality after construction, when the rotating disk 908 drives the convex rod 909 to rotate upward, the convex rod 909 drives the reciprocating frame 1001 to move upward, and through the connecting rod 1002, it drives the auxiliary cylinder 1003 to move upward. At this time, because the limiting block 1006 is tilted downward, it cannot drive the hollow tube 1101 to move upward through the limiting block 1006, so that the buffer pad 1103 always abuts against the top of the grounding angle steel, which facilitates the effect of multiple strikes on the grounding angle steel. Under the abutment action of the buffer pad 1103, the impact of the hammer 1102 can be buffered, preventing the hammer 1102 from damaging the grounding angle steel, thereby preventing the deformation of the grounding angle steel during the striking process and improving the safety of construction.

[0051] It should be noted that the components in this application are all general standard parts or parts known to those skilled in the art, which effectively solves the problem of reduced construction efficiency and effectiveness of grounding angle steel by existing manual labor and large machinery.
