DETAILED DESCRIPTION

[0017] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0018] See also Figures 1 to 3 The utility model provides a technical solution: a longitudinal wet joint bottom mold erecting device, including a cross beam A1, a cross beam B2 is arranged on one side of the cross beam A1, a gap 3 is provided between the cross beam B2 and the cross beam A1, a bottom mold erecting mechanism is arranged at the bottom end of the gap 3, and a mounting docking mechanism is arranged on the surfaces of the cross beams A1 and B2. The bottom mold erecting mechanism includes: a bottom mold assembly, which is arranged at the bottom end of the gap 3; a locking assembly, which is arranged inside the bottom mold assembly; and a limit assembly, which is arranged on both sides of the bottom mold assembly.

[0019] In this embodiment, preferably, the bottom mold assembly includes a bottom mold 100 arranged at the bottom end of the gap 3 and a limiting top plate 101 arranged at the top end of the bottom mold 100 and passing through the inside of the gap 3.

[0020] In this embodiment, preferably, guide grooves 200 are provided at the bottom ends of the beams A1 and B2, and guide blocks 201 are symmetrically fixed to the top of the bottom mold 100, which are snap-connected with the guide grooves 200 to facilitate the bottom mold 100 to fit with the bottom ends of the beams.

[0021] In this embodiment, preferably, the locking assembly includes a through hole 300 symmetrically fixed at the top of the limiting top plate 101 and an adjusting screw 301 symmetrically fixed at the top of the bottom mold 100 and passing through the gap 3. The adjusting screw 301 is slidably connected to the through hole 300, and a butterfly nut 302 screwed together with the adjusting screw 301 is provided at the top of the limiting top plate 101, so that the position of the limiting top plate 101 can be adjusted.

[0022] In this embodiment, preferably, the limiting assembly includes built-in grooves 400 symmetrically opened on both sides of the limiting top plate 101 and a limiting block 401 arranged inside the built-in groove 400, and a built-in spring 402 is connected between the limiting block 401 and the built-in groove 400, which can drive the limiting block 401 to reset and bounce up.

[0023] In this embodiment, preferably, the inner wall of the built-in groove 400 is symmetrically provided with a slide groove 500 and sliders 501 symmetrically fixed on both sides of the limit block 401, and the sliders 501 are slidably connected to the slide groove 500, so as to play a guiding role when the limit block 401 moves.

[0024] In this embodiment, preferably, the installation docking mechanism includes a docking groove 600 provided on the surface of the beam A1 and the beam B2 and a docking block 601 symmetrically fixed inside the docking groove 600, which can play a guiding role when the beams are connected.

[0025] The working principle and use process of the utility model are as follows: when the bottom mold 100 and the gap 3 need to be installed and erected, the limiting top plate 101 is first embedded into the inside of the gap 3 from the bottom end, and the limiting block 401 is squeezed with the inner wall of the bottom end of the gap 3. The limiting block 401 is squeezed by the external force to shrink the built-in spring 402 into the inside of the built-in groove 400, and at the same time drives the slider 501 to slide inside the slide groove 500 to play a moving guide role, so that the limiting top plate 101 can pass through the inside of the gap 3. At this time, the limiting block 401 is reset and popped out from the inside of the built-in groove 400 under the action of the built-in spring 402, so that the built-in spring 402 on the left side fits with the top of the beam B2, and the right side is pressed against the inner wall of the gap 3. The built-in spring 402 on the side fits with the top of the beam A1, and at the same time, the top of the bottom mold 100 fits with the bottom ends of the beams A1 and B2, and drives the guide block 201 to embed into the inside of the guide groove 200 to play a docking guide role, and then tighten the butterfly nut 302 to make it rotate on the surface of the adjusting screw 301, and push the limiting top plate 101 to slide on the surface of the adjusting screw 301 through the through hole 300, so that the bottom end of the limiting block 401 can fit tightly with the top of the beam A1 and the beam B2, which plays the role of setting up the bottom mold 100. When it is necessary to connect the beam A1 to other beams, it can play a docking guide role with the docking groove 600 and the docking block 601.
