[0025] Furthermore, each set of first ear plates 30 includes two first ear plates 30 respectively located on both sides of the cone rod 50 , and each set of second ear plates 40 includes two second ear plates 40 respectively located on both sides of the cone rod 50 .

[0026] An embodiment of the present application provides a railway roadbed grouting reinforcement device. During its actual use, when grouting is required, the railway roadbed grouting reinforcement device is placed at the crack, the cone rod 50 is swung to a vertical state, the locking piece 60 is inserted into the third through hole 52 and the second through hole 41, the position of the cone rod 50 is locked, and the cone rod 50 is inserted into the ground, and then the grouting pipe 20 is inserted into the socket 11 for grouting.

[0027] After the grouting is completed, the grouting pipe 20 is pulled out from the socket 11, the support plate 10 is lifted up, and the cone rod 50 is lifted off the ground. The locking piece 60 is pulled out, and the cone rod 50 is swung to a horizontal state for storage.

[0028] Compared with the prior art, the railway roadbed grouting reinforcement device provided in this embodiment has the following characteristics: after grouting is completed, the grouting pipe 20 is pulled out from the insertion hole 11, the support plate 10 is lifted up, and the cone rod 50 is separated from the ground. After the locking piece 60 is pulled out, the cone rod 50 is swung to a horizontal state for storage, and the locking piece 60 is inserted into the third through hole 52 and the first through hole 31 to lock the position of the cone rod 50, thereby avoiding injuries to workers during transportation and eliminating safety hazards.

[0029] In a possible implementation, the support plate 10 is formed as follows: Figures 1 to 3 The structure shown, see Figures 1 to 3 The support plate 10 is provided with four groups of avoidance grooves 13 corresponding to the first ear plates 30 one by one. The avoidance grooves 13 extend to the outer peripheral edge of the support plate 10, and the positioning plate 51 can enter the avoidance grooves 13 under the drive of the cone rod 50.

[0030] Specifically, the avoidance groove 13 is provided to avoid the positioning plate 51, so that when the cone rod 50 swings toward the vertical state, it enters the avoidance groove 13 to avoid interference with the support plate 10, and when the cone rod 50 swings to the vertical state, the bottom wall of the avoidance groove 13 just abuts against the positioning plate 51, thereby limiting the positioning plate 51 and avoiding the cone rod 50 from swinging transition.

[0031] In a possible implementation, the locking member 60 is configured as follows: Figure 1 and Figure 3 The structure shown, see Figure 1 and Figure 3 One end of the locking member 60 is provided with a limiting platform 61 protruding toward the periphery.

[0032] Specifically, the limiting platform 61 is used to contact and cooperate with the outer side wall of the first ear plate 30 or the second ear plate 40 to limit the locking member 60 to prevent it from falling off due to the plug-in transition.

[0033] In some embodiments, see Figure 1 、 Figure 3 and Figure 4 A limiting cap 70 is sleeved on one end of the locking member 60 away from the limiting platform 61 , and a magnet 71 for adsorbing the locking member 60 is provided on the inner bottom wall of the limiting cap 70 .

[0034] Specifically, the limiting cap 70 can contact and cooperate with the outer wall of the first ear plate 30 or the second ear plate 40, and through the adsorption of the magnet 71 and the locking piece 60, the limiting cap 70 is stably mounted on the outer periphery of the locking piece 60. Through the cooperation of the limiting platform 61 and the limiting cap 70, the locking piece 60 is prevented from falling out of the third through hole 52 and the first through hole 31 or the third through hole 52 and the second through hole 41 due to accidental vibration, thereby improving the locking stability and also improving the stability of the installation and disassembly of the locking piece 60 and the limiting cap 70.

[0035] In a possible implementation, the support plate 10 is formed as follows: Figure 1 The structure shown, see Figure 1 The top of the support plate 10 is connected to two clamping members 80 for sliding in the horizontal direction. The two clamping members 80 are arranged opposite to each other and are respectively located on both sides of the grouting pipe 20. The two clamping members 80 can move toward each other to clamp the grouting pipe 20.

[0036] Specifically, the two clamping members 80 are used to clamp the grouting pipe 20 from both sides, thereby preventing the grouting pipe 20 from moving up and down, and improving the stability of use.

[0037] In some embodiments, see Figure 1 The top of the support plate 10 is connected to the mounting plate 14, and the clamping member 80 includes a sliding rod 81, an arc plate 82 and an elastic member 83. The sliding rod 81 passes through the mounting plate 14 horizontally along the radial direction of the support plate 10 and is slidably connected to the mounting plate 14; the arc plate 82 is connected to one end of the sliding rod 81 close to the grouting pipe 20, and is used to abut against the outer peripheral wall of the grouting pipe 20; the elastic member 83 is sleeved on the outer periphery of the sliding rod 81 and is located between the arc plate 82 and the mounting plate 14. One end of the elastic member 83 is connected to the arc plate 82 and the other end is connected to the mounting plate 14, and is used to elastically push the arc plate 82.

[0038] Specifically, when the grouting pipe 20 needs to be installed, the two sliding rods 81 are pulled in opposite directions, the arc plate 82 compresses the elastic part 83, and the grouting pipe 20 is inserted into the socket 11. After being inserted to a predetermined depth, the two sliding rods 81 are released. Under the push of the elastic part 83, the two arc plates 82 move toward each other and abut against the outer wall of the grouting pipe 20, thereby clamping the grouting pipe 20, avoiding the up and down movement of the grouting pipe 20, and improving the stability of use.

[0039] In a possible implementation, the grouting pipe 20 is Figures 1 to 3 The structure shown, see Figures 1 to 3 A positioning groove 21 extending in the up-down direction is provided on the outer peripheral wall of the grouting pipe 20 , and a positioning block 12 slidingly matched with the positioning groove 21 is provided on the inner peripheral wall of the insertion hole 11 .

[0040] Specifically, through the mutual limitation of the positioning block 12 and the positioning groove 21, the grouting pipe 20 can only move up and down in the socket 11, thereby avoiding the rotation of the grouting pipe 20 and improving the circumferential stability of the grouting pipe 20.

[0041] The above are only preferred embodiments of the present invention and are not intended to limit the present invention. Any modifications, equivalent replacements and improvements made within the spirit and principles of the present invention should be included in the scope of protection of the present invention.
