Description

Technical Field

[0001] The utility model belongs to the technical field of building construction equipment, in particular to a civil engineering building pillar component. Background Art

[0002] The role of building pillars is to provide one or more stable support points for cast-in-place floors or cast-in-place surfaces. Most existing building pillars are supported by a support column with adjustable height. After adjusting the length of the support column, the top is tightly supported by the upper building.

[0003] For example, Chinese utility model CN219887672U discloses a civil engineering building support. When two sliders move toward each other, the angle between two connecting rods and corresponding movable blocks decreases, so that the two movable blocks drive the support rod to move upward, thereby increasing the support height of the support rod.

[0004] Furthermore, through the cooperation between the claw and the tooth groove of the tooth plate, the claw supports the tooth plate, and also supports the support rod, sharing the force on the connecting shaft of the connecting rod and the movable block. By rotating the screw, the screw drives the rack to move upward and mesh with the gear, and then the gear rotates, so that the claw rotates and disengages from the tooth plate, and the claw releases the restriction on the tooth plate.

[0005] However, in the above-mentioned prior art, since the support rod is subjected to a downward force, the tooth plate exerts a downward force on the claw, which causes the rotation of the claw to encounter great resistance when the contact claw restricts the tooth plate, making it more laborious and inconvenient to operate the screw, resulting in poor overall ease of use. Utility Model Content

[0006] The utility model aims to provide a civil engineering building pillar assembly, in which a limiting rod cooperating with a limiting rack is movably inserted through the side wall of a fixed cylinder, and a wedge block is used to squeeze and push the lever, so that the limiting rod is separated from the limiting rack, thereby solving the problem of poor overall convenience of use of existing building pillars.

[0007] In order to solve the above technical problems, the utility model is realized by the following technical solutions:

[0010] As a preferred technical solution of the utility model, a flat cut surface is provided on the upper side of the limit rod for cooperating with the lower surface of the limit rack through the flat cut surface.

[0011] As a preferred technical solution of the utility model, there are two limit racks, and the two limit racks are symmetrically arranged.

[0012] As a preferred technical solution of the utility model, the screw rod is rotatably connected with a U-shaped block, and two wedge-shaped blocks are respectively located at two ends of the U-shaped block, and are used to synchronously drive the two wedge-shaped blocks to move through the U-shaped block.

[0013] As a preferred technical solution of the utility model, a sleeve cooperating with the limiting insertion rod is fixedly connected to the side wall of the fixing cylinder, and is used to support the limiting insertion rod through the sleeve.

[0014] As a preferred technical solution of the utility model, the lifting mechanism includes a bidirectional screw and two sliding blocks cooperating with the bidirectional screw, and the two sliding blocks are respectively hinged to the support column through a connecting rod; wherein, one end of the bidirectional screw is fixedly connected to a worm gear, the base is rotatably connected to a worm meshing with the worm gear, and one end of the worm gear is fixedly connected to a hand wheel.

[0015] The utility model has the following beneficial effects:

[0016] The utility model uses a limit rod that cooperates with the limit rack and is movably inserted through the side wall of the fixed cylinder. The limit rack is formed into a sawtooth structure and the lower surface is a flat structure. The screw is rotated to drive the wedge block to move, so that the wedge block pushes the lever to separate the limit rod from the limit rack.

Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments.

[0032] Embodiment 1

[0033] See also Figures 1 to 3 As shown in Figures 6 and 7, the utility model is a civil engineering building pillar assembly, comprising a base 1, a fixed tube 2, a support column 3 sleeved in the fixed tube 2, and a lifting mechanism 5. The lifting mechanism 5 comprises a bidirectional screw 501 and two sliders 502 matched with the bidirectional screw 501. The bidirectional screw 501 is rotatably connected to the base 1 through a bearing seat, the sliders 502 and the bidirectional screw 501 are threadedly matched, and the two sliders 502 are respectively hinged to the support column 3 through a connecting rod 503; the side wall of the fixed tube 2 is provided with a strip-shaped avoidance notch for connecting the connecting rod 503 with the support column 3.

[0034] One end of the bidirectional screw 501 is fixedly connected to a worm gear 504, and the base 1 is rotatably connected to a worm 505 meshing with the worm gear 504, and one end of the worm gear 504 is fixedly connected to a hand-cranked wheel 506, which is used to rotate the worm 505 through the hand-cranked wheel 506, and use the worm gear 504 to drive the bidirectional screw 501 to move through two sliders 502, and use the connecting rod 503 to drive the support column 3 to rise and fall.

[0035] The worm wheel 504 and the worm 505 are used for transmission, so that the rotation of the bidirectional screw 501 is more labor-saving, and the hand wheel 506 is located directly above the base 1 at this time, which is easy to operate and avoids the situation of being affected by the ground during the rotation process.

[0036] like Figure 4 , 5 As shown in FIG. 7 , two mounting grooves 301 are provided on the circumferential surface of the support column 3. The mounting grooves 301 are arranged along the axial direction of the support column 3, and a limiting rack 302 is fixedly connected in the mounting grooves 301. The teeth of the limiting rack 302 are in a serrated structure, and the lower surface is a planar structure.

[0037] The side wall of the fixed cylinder 2 is provided with a through hole, and a limit rod 4 corresponding to the position of the limit rack 302 is inserted through the through hole. In addition, a sleeve 204 matching the limit rod 4 is welded to the side wall of the fixed cylinder 2, which is used to support the limit rod 4 through the sleeve 204.

[0038] One end of the limiting rod 4 is a wedge-shaped structure, which is used to be inserted into the installation groove 301 through the limiting rod 4 and cooperate with the limiting rack 302, that is, the limiting rod 4 is inserted between the teeth of two adjacent limiting racks 302 to limit the support column 3.

[0039] Among them, Figure 8 and 9 As shown, a flat cut surface 404 is provided on the upper side of the limiting plug rod 4, which is used to cooperate with the lower surface of the teeth of the limiting rack 302 through the flat cut surface 404, thereby increasing the contact area between the teeth of the limiting rack 302 and the limiting plug rod 4, reducing the mutual pressure, and improving the stability of the cooperation.

[0040] The limit rod 4 is fixedly connected to a radially arranged lever 403, one end of which is welded or threadedly connected to a guide rod 401, or the limit rod 4 and the guide rod 401 are an integrated stepped shaft structure. The guide rod 401 is sleeved with a spring 402.

[0041] The fixed cylinder 2 is welded with an annular plate 201, and the annular plate 201 is provided with a straight notch 202 that is clearance-matched with the lever 403, and the straight notch 202 is arranged parallel to the axial direction of the limiting plug rod 4. The annular plate 201 is welded or screwed with a stopper 203, and the stopper 203 is provided with a through hole that is matched with the guide rod 401. One end of the spring 402 abuts against the side of the stopper 203, and the other end pushes against the end face of the limiting plug rod 4, which is used to push the limiting plug rod 4 through the spring 402, so that the limiting plug rod 4 moves toward the fixed cylinder 2, so that the limiting plug rod 4 maintains a matching state with the limiting rack 302, and the limiting plug rod 4 is prevented from slipping off, so that the overall reliability of use is improved.

[0042] The annular plate 201 is welded or screwed with a fixing block, the fixing block is provided with a threaded hole and is threadedly connected with a screw rod 6, the screw rod 6 is rotatably connected with a wedge block 601, which is used to rotate through the screw rod 6 and drive the wedge block 601 to move through the axial movement of the screw rod 6, and the inclined portion of the wedge block 601 is used to squeeze the lever 403, thereby pulling the limit rod 4 to move axially through the lever 403, so that the limit rod 4 moves toward the outside of the fixed tube 2 and separates from the limit rack 302, and the support column 3 can be lowered at this time.

[0043] The support column 3 needs to be raised, and the wedge block 601 is moved by the screw rod 6, so that the wedge block 601 releases the pushing of the lever 403, and the limit rod 4 is axially pushed away by the spring 402. When the support column 3 is raised by the lifting mechanism 5, the inclined surface of the teeth of the limit rack 302 cooperates with the inclined surface of the wedge-shaped end of the limit rod 4, so that the limit rod 4 is lowered and pushed toward the outside of the fixed cylinder 2.

[0044] Moreover, after the limit rod 4 passes over the teeth, the limit rod 4 is reinserted between two adjacent teeth under the action of the spring 402, so that the support column 3 can only be raised but not lowered, reducing the process of manually inserting the limit rod 4, thereby greatly improving the overall convenience and reliability of use.

[0045] Embodiment 2

[0046] Based on the first embodiment, Figure 8 and 9 As shown, there are two mounting grooves 301 , which are symmetrically arranged relative to the support column 3 , so there are also two limiting racks 302 , which are symmetrically arranged.

[0047] The screw rod 6 is rotatably connected to a U-shaped block 602, and two wedge blocks 601 are respectively located at the two ends of the U-shaped block 602. The wedge block 601 and the U-shaped block 602 can be an integrated structure, or fixed by welding, so that the two wedge blocks 601 can be synchronously driven to move by the U-shaped block 602, that is, the positions of the two wedge blocks 601 can be adjusted by setting a screw rod 6, thereby further improving the convenience of use.
