The concrete mixing box 20 is installed on the base 10, and the mixing box 30 is installed on the concrete mixing box 20. A connecting pipe 40 is connected between the mixing box 30 and the concrete mixing box 20, and a casting pipe 50 is installed on the side of the mixing box 30 away from the concrete mixing box 20. The specific structures of the base 10, the concrete mixing box 20 and the mixing box 30 are all prior arts and are not described in detail here. A horizontal support frame 60 is fixed to the side of the mixing box 30 close to the concrete mixing box 20, and a vertical fixing plate 70 is fixed to the end of the support frame 60 away from the mixing box 30. A connector assembly 80 is provided at the relative position of the fixing plate 70 and the concrete mixing box 20, so as to detachably connect the fixing plate 70 to the concrete mixing box 20.

By providing the fixing plate 70 and the connector assembly 80, the mixing box 30 and the concrete mixing box 20 can be detachably connected, which is convenient for transportation and storage of the grouting device.

[0037] Specifically, Figure 2 and Figure 3 As shown, the connector assembly 80 includes a connector post 81, a clamping block 82 and a push-pull rod 83. The connector post 81 passes through the fixing plate 70 and is inserted into the concrete mixing box 20. The clamping block 82 is arranged at one end of the connector post 81 close to the concrete mixing box 20. The push-pull rod 83 is arranged in the connector post 81 and abuts against the clamping block 82. It can move along the axial direction of the connector post 81, so that the clamping block 82 moves up and down perpendicular to the axial direction of the connector post 81 and engages or disengages with the concrete mixing box 20. In this embodiment, a through hole 71 is provided on the fixing plate 70, and a groove 21 is provided at a relative position of the concrete mixing box 20 and the through hole 71. The connector post 81 passes through the through hole 71 perpendicular to the fixing plate 70 and is inserted into the groove 21 of the concrete mixing box 20. A boss 811 is integrally provided at one end of the plug-in column 81 away from the concrete mixing box 20. When the plug-in column 81 is inserted into the concrete mixing box 20, the boss 811 contacts the side of the fixing plate 70 away from the concrete mixing box 20 to play a positioning role. A clamping block 82 is provided at one end of the plug-in column 81 close to the concrete mixing box 20, that is, the clamping block 82 is provided at one end of the plug-in column 81 inserted into the groove 21 of the concrete mixing box 20. The number of the clamping blocks 82 is not limited. Preferably, two symmetrically arranged clamping blocks 82 are provided on the plug-in column, which are respectively located on the upper and lower sides of the plug-in column 81. A clamping groove 22 is provided at a position of the groove 21 relative to the clamping block 82, and the clamping block 82 can be clamped with the clamping groove 22. A horizontal push-pull rod 83 is sleeved inside the plug-in column 81, and the upper and lower sides of the push-pull rod 83 are respectively in contact with the two clamping blocks 82. The push-pull rod 83 is loosely matched with the plug column 81 and can move along the axial direction of the plug column 81, so that the clamping block 82 moves up and down perpendicular to the axial direction of the plug column 81 to engage or disengage with the clamping groove 22. In order to facilitate the movement of the push-pull rod 83, a push-pull head 831 is fixed to the end of the push-pull rod 83 away from the concrete mixing box 20.

[0038] Specifically, an abutment block 84 is provided at one end of the push-pull rod 83 close to the concrete mixing box 20, and the abutment block 84 abuts against the clamping block 82. In this embodiment, an abutment block 84 is integrally provided at one end of the push-pull rod 83 inserted into the concrete mixing box 20, and the upper and lower sides of the abutment block 84 respectively abut against two clamping blocks 82. Moving the push-pull rod 83 can drive the abutment block 84 to move axially along the plug-in column 81, and the two clamping blocks 82 can move up and down perpendicular to the axial direction of the plug-in column 81 under the drive of the abutment block 84.

[0039] Specifically, the abutting block 84 is provided with an abutting inclined surface 841, and one end of the clamping block 82 close to the abutting block 84 is adapted to the abutting inclined surface 841. In this embodiment, the abutting inclined surfaces 841 are symmetrically provided on the upper and lower sides of the abutting block 84, and one end of the clamping block 82 close to the abutting block 84 is adapted to the abutting inclined surface 841 and can slide along the abutting inclined surface 841. When the abutting block 84 moves toward the concrete mixing box 20, the clamping block 82 can move away from the clamping groove 22 along the abutting inclined surface 841 and disengage from the clamping groove 22; when the abutting block 84 moves away from the concrete mixing box 20, the clamping block 82 can move toward the clamping groove 22 along the abutting inclined surface 841 and engage with the clamping groove 22.

[0040] Specifically, Figure 3 As shown, the connector column 81 is provided with a stepped hole 812, and the clamping block 82 passes through the stepped hole 812 and is clamped with the concrete mixing box 20. In this embodiment, the clamping block 82 includes an integrally arranged clamping portion 821 and an abutting portion 822, the clamping portion 821 is used to be clamped with the clamping groove 22, the abutting portion 822 is used to abut with the abutting block 84, and one end of the abutting portion 822 close to the abutting block 84 is adapted to the abutting inclined surface 841 and can slide along the abutting inclined surface 841. A stepped hole 812 is provided on the connector column 81 at a position opposite to the clamping block 82, and the clamping block 82 is clearance-matched with the stepped hole 812 and can move up and down along the stepped hole 812, and the stepped hole 812 serves as a limit for the clamping block 82.

[0041] Specifically, in order to enable the clamping block 82 to quickly disengage from the clamping groove 22, a first elastic member 85 is sleeved on the clamping block 82, and the first elastic member 85 abuts against the stepped hole 812. In this embodiment, the first elastic member 85 is specifically a spring, which is sleeved on the clamping portion 821 of the clamping block 82, with one end in contact with the abutting portion 822 and the other end abutting against the step of the stepped hole 812. When the abutting block 84 moves toward the concrete mixing box 20, the clamping block 82 can move away from the clamping groove 22 along the abutting inclined surface 841 under the elastic force of the first elastic member 85, and quickly disengage from the clamping groove 22.

[0042] Specifically, a second elastic member 86 is provided at one end of the connector column 81 close to the concrete mixing box 20, and the second elastic member 86 is connected to a side of the abutment block 84 away from the push-pull rod 83. In this embodiment, the second elastic member 86 is specifically a spring, which pushes the push-pull rod 83 to drive the abutment block 84 to move toward the concrete mixing box 20, and the first elastic member 85 rebounds to disengage the clamping block 82 from the clamping groove 22, and the second elastic member 86 is in a compressed state. When the push-pull rod 83 is released, the second elastic member 86 rebounds to move the abutment block 84 toward the fixing plate 70, and the clamping block 82 is quickly engaged with the clamping groove 22 driven by the abutment block 84.

[0043] Specifically, a positioning block 87 is provided in the connector column 81, and the push-pull rod 83 passes through the positioning block 87 and is provided with an abutment block 84. In this embodiment, in order to prevent the clamping block 82 from being separated from the abutment block 84, a positioning block 87 is fixed in the connector column 81, and the push-pull rod 83 passes through the positioning block 87 and is in clearance with the positioning block 87.

[0044] Specifically, the push-pull rod 83 is sleeved with a third elastic member 88, which is arranged on the side of the positioning block 87 away from the abutment block 84. In this embodiment, the third elastic member 88 is specifically a spring, which is sleeved on the push-pull rod 83, with one end abutting against the push-pull rod 83 and the other end abutting against the side of the positioning plate away from the abutment block 84.

At this time, the plug column 81 is inserted into the concrete mixing box 20 through the through hole 71, and the push-pull head 831 is released. The second elastic member 86 and the third elastic member 88 rebound, so that the abutment block 84 moves toward the fixed plate 70. Driven by the abutment block 84, the clamping block 82 moves away from the abutment block 84 along the abutment slope 841 and quickly engages with the clamping groove 22. At this time, the first elastic member 85 is in a compressed state. The mixing box 30 and the concrete mixing box 20 are detachably connected through the plug assembly 80.

[0048] Carry out grouting.

[0049] After grouting is completed, the push-pull head 831 is pushed, so that the push-pull rod 83 drives the abutment block 84 to move along the axial direction of the plug column 81, so that the second elastic member 86 and the third elastic member 88 are compressed, and the clamping block 82 moves toward the abutment block 84 along the abutment slope 841 under the elastic force of the first elastic member 85, enters the plug column 81, and disengages from the clamping groove 22. The entire plug assembly 80 is pulled out to separate the mixing box 30 and the concrete mixing box 20 for subsequent transportation and storage.
