Description

Technical Field

[0001] This invention relates to the field of building construction, and in particular to a material lifting and stabilizing support mechanism for building construction. Background Technology

[0002] In the vertical material transportation operations of low-rise buildings (such as self-built houses, villas, and elevator installations in old residential areas), rooftop scaffolding in conjunction with winches and wire ropes is commonly used to lift materials such as cement, bricks, and mortar. This simple lifting equipment has a simple structure and low cost, but its stability when stopping at different floors for loading and unloading materials has long been a problem that has not been effectively solved.

[0003] In actual construction, when the support platform carrying materials is raised to the target floor and ready to unload, it often sways continuously due to factors such as the elastic elongation of the wire rope, the impact of the winch starting and stopping, wind force, and installation errors of the gantry. At this time, operators need to unload the materials from the swaying platform, which is not only labor-intensive and inefficient, but also poses safety hazards such as material tipping over, falling debris causing injury, and platform overturning. Especially when loading and unloading heavy materials (such as bags of cement or full buckets of mortar), operators cannot stabilize the platform with one hand and pick up the material with the other, often requiring multiple people or temporary supports, further reducing construction efficiency. Summary of the Invention

[0004] This invention discloses a material lifting and stabilizing support mechanism for construction, which aims to solve the technical problem that operators cannot stabilize the platform with one hand and pick up materials with the other, often requiring multiple people to cooperate or to use temporary supports, which further reduces construction efficiency.

[0005] To achieve the above objectives, the present invention adopts the following technical solution: A material lifting and stabilizing support mechanism for construction includes a hanger and further includes: a stabilizing mechanism mounted on a sub-frame via the support mechanism; an auxiliary positioning mechanism mounted on the support mechanism; and a pull rope movably wound around the hanger, with one end of the pull rope connected to an external winch and the other end fixedly connected to a support platform. The stabilizing mechanism includes: a cylindrical base fixedly connected to the bottom outer wall of the support platform; a bearing frame connected to the support mechanism; connecting rods symmetrically arranged and rotatably connected to the bearing frame via hinge shafts; gears meshing with each other and rotatably connected to the bearing frame, with a motor drivingly connected to one side outer wall of one of the gears; multiple synchronous pulleys fixedly connected to the top outer wall of each hinge shaft and gear, with synchronous belts simultaneously sleeved on corresponding two synchronous pulleys; a V-shaped clamping frame fixedly connected to the ends of two connecting rods; an arc-shaped groove fixedly connected to the bottom outer wall of the bearing frame; and an arc-shaped base frame movably engaged in two arc-shaped grooves, with the top of the arc-shaped base frame movably fitting against the bottom end of the connecting rod. Each of the arc-shaped base frames has a slider fixedly connected to its bottom outer wall, and each of the arc-shaped grooves has an arc-shaped through groove through its bottom inner wall, with each slider being movably engaged in the corresponding arc-shaped through groove.

[0006] With a stabilizing mechanism, the inner side of the V-shaped clamping frame is a V-shaped bevel. During the clamping of the cylindrical base, it automatically pushes the support platform to the center position, eliminating positional deviations caused by winch lifting deviations or rope swaying, significantly reducing the requirements for the positioning accuracy of the lifting system. After the V-shaped clamping frame clamps the cylindrical base, the winch can release the rope, allowing the load on the support platform to be entirely borne by the stabilizing mechanism, avoiding elastic swaying of the rope. Simultaneously, the arc-shaped base frame at the bottom of the connecting rod extends manually during clamping, providing auxiliary rigid support for the connecting rod and ensuring support stability during material loading and unloading.

[0007] In a preferred embodiment, the auxiliary positioning mechanism includes: a second snap-fit ​​groove, which is fixedly connected to the outer periphery of the lower screw tube; and a hinge seat, one end of which is movably snapped into the second snap-fit ​​groove, and the snap-fit ​​surface of the hinge seat is fixedly wrapped with a damping sleeve. The auxiliary positioning mechanism further includes: a second hinge shaft, rotatably connected to the hinge seat; an extension plate, fixedly connected to one side of the outer wall of the second hinge shaft; and a torsion spring, one end of which is connected to the bottom end of the hinge seat and the other end of which is connected to the second hinge shaft. The auxiliary positioning mechanism further includes: a pointer, fixedly connected to the top of the second hinge shaft; and an indicator, set on the top outer wall of the hinge seat.

[0008] Equipped with an auxiliary positioning mechanism, the entire support and stabilizing mechanism can be precisely positioned directly below the pull rope. This ensures that after the support platform is raised into place, the cylindrical base can accurately enter the clamping area of ​​the two V-shaped clamping frames, avoiding clamping failure or off-center loading problems caused by installation position deviations. This "what you see is what you get" indication method eliminates the need for professional measuring tools, allowing ordinary workers to quickly and accurately complete installation and positioning, lowering the construction threshold. It requires no complex sensors or electronic components, has low manufacturing costs, and is not easily damaged, making it suitable for harsh on-site environments.

[0009] In a preferred embodiment, the support mechanism includes: a U-shaped frame, which is movably snapped onto the sub-frame; multiple screw holes, which are simultaneously provided on one inner wall of the U-shaped frame, and each screw hole is movably engaged with a limit screw; and a support frame, which is fixedly connected to the top outer wall of the U-shaped frame. The support mechanism further includes: a snap-fit ​​groove, fixed to the top outer wall of the support frame; a square base, movably snapped into the snap-fit ​​groove; and two screw tubes, one of which has its bottom end fixedly connected to the top outer wall of the square base. The support mechanism further includes: a top plate, fixedly connected to the outer wall of the top end of another spiral tube; a double-ended screw, the two ends of which are respectively engaged in the two spiral tubes; and a sliding groove, provided on one inner wall of the U-shaped frame. The support mechanism further includes: a sliding frame, which is movably engaged in the sliding groove; multiple springs, which are simultaneously fixedly connected to the top outer wall of the sliding frame, and the other ends of the multiple springs are simultaneously fixed to the top inner wall of the sliding groove; and multiple rollers, which are simultaneously rotatably connected to the opposite inner walls of the sliding frame.

[0010] By incorporating a support mechanism and multiple rollers that roll in contact with the sub-frame surface, the entire stabilizing mechanism can move freely laterally along the sub-frame during initial installation. This allows operators to accurately position the equipment according to site conditions, eliminating the need for repeated lifting or moving and reducing installation labor intensity. Multiple lower limiting screws achieve horizontal clamping, while the upper double-ended screw and screw tube assembly achieve vertical clamping, forming a "lower clamp, upper push" bidirectional fixing mode. This effectively resists loads from all directions generated during material lifting and unloading, ensuring the stabilizing mechanism does not shift during use. As the double-ended screw pushes upwards against the inner wall of the sub-frame top, the downward reaction force on the U-shaped frame automatically compresses the spring, causing the rollers to retract, ultimately resulting in the inner wall of the U-shaped frame directly abutting against the sub-frame surface. This process eliminates installation gaps, achieves rigid contact, and avoids micro-movements caused by the presence of elastic elements.

[0011] As described above, a material lifting and stabilizing support mechanism for construction includes a hanger, and further includes: a stabilizing mechanism installed on a sub-frame via the support mechanism; an auxiliary positioning mechanism installed on the support mechanism; and a pull rope movably wound around the hanger, with one end of the pull rope connected to an external winch and the other end fixedly connected to a support platform. The stabilizing mechanism includes: a columnar base fixedly connected to the bottom outer wall of the support platform; a bearing frame connected to the support mechanism; and two connecting rods symmetrically arranged and rotatably connected to the bearing frame via hinge shafts. Two gears, meshing with each other and rotatably connected to a bearing bracket, are included. A motor is connected to one side of the outer wall of one of the gears. Multiple synchronous pulleys are fixedly connected to the top outer wall of each hinge shaft and gear, and synchronous belts are simultaneously fitted onto corresponding pairs of synchronous pulleys. Two V-shaped clamping frames are fixedly connected to the ends of two connecting rods. Two arc-shaped grooves are fixedly connected to the bottom outer wall of the bearing bracket. Two arc-shaped base frames are movably engaged within the two arc-shaped grooves, with the top of the arc-shaped base frames movably fitting against the bottom of the connecting rods. The material lifting and stabilizing support mechanism for construction materials provided by this invention has the technical effect of ensuring the stability of support during material loading and unloading.

[0018] The technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present invention. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments.

[0019] The material lifting and stabilizing support mechanism disclosed in this invention is mainly used in building construction scenarios.

[0020] Reference Figure 1 and Figure 2 A material lifting and stabilizing support mechanism for construction work includes a hanger 1 installed at a suitable position on the top of the building. A pull rope 2 is movably wound around the hanger 1, with one end connected to a ground winch and the other end fixedly connected to a support platform 3 for supporting materials. A columnar base 401 is fixedly connected to the outer wall of the bottom end of the support platform 3.

[0021] The stabilizing mechanism 4 is fixedly installed on the sub-frame of the target floor via the supporting mechanism 5. The bearing bracket 413 of the stabilizing mechanism 4 is fixedly connected to the supporting mechanism 5. Two connecting rods 403 are symmetrically arranged on the bearing bracket 413, and each connecting rod 403 is rotatably connected to the bearing bracket 413 via a hinge shaft 405. A V-shaped clamping bracket 402 is fixedly connected to the end of each of the two connecting rods 403. The clamping surfaces of the two V-shaped clamping brackets 402 are arranged opposite each other, and the clamping surfaces have a V-shaped inclined structure.

[0022] To achieve synchronous reverse movement of the two connecting rods 403, two meshing gears 410 are simultaneously rotatably connected to the bearing bracket 413, with one gear 410 being connected to the output end of the motor 412. A synchronous pulley 411 is fixedly connected to the top of each hinge shaft 405 and the top of each gear 410, and a synchronous belt 409 is simultaneously sleeved on the corresponding two synchronous pulleys 411.

[0023] When the motor 412 starts, the gear 410 directly connected to it rotates, driving another gear 410 to rotate synchronously in the opposite direction through meshing transmission; at the same time, the synchronous pulley 411 at the top of the gear 410 transmits power to the synchronous pulley 411 at the top of the hinge shaft 405 through the synchronous belt 409, thereby driving the two connecting rods 403 to rotate synchronously inward or outward around their respective hinge shafts 405.

[0024] Two arc-shaped grooves 406 are fixedly connected to the outer wall of the bottom end of the bearing bracket 413. An arc-shaped base frame 404 is movably engaged in each arc-shaped groove 406, and the top of the arc-shaped base frame 404 is movably attached to the bottom end of the corresponding connecting rod 403.

[0025] In the initial state, the two connecting rods 403 are in an outward-opening state, the two V-shaped clamps 402 are far apart from each other, and the arc-shaped base 404 is placed in the arc-shaped groove 406.

[0026] The winch drives the support platform 3 to rise via the pull rope 2. When the support platform 3 reaches the target floor, the external control system or manual triggering of the motor 412 causes the two connecting rods 403 to rotate inward synchronously. The two V-shaped clamps 402 then move inward synchronously, gradually approaching and contacting the cylindrical base 401 from both sides. During this process, the V-shaped ramp forces the cylindrical base 401 to automatically slide towards the central symmetrical plane of the two V-shaped clamps 402, achieving automatic centering and correction of the support platform 3.

[0027] After the two V-shaped clamping frames 402 initially clamp the cylindrical base 401, the operator manually pulls the arc-shaped base frame 404 outward along the arc-shaped groove 406, so that its top end abuts against the bottom end of the connecting rod 403, providing auxiliary rigid support for the connecting rod 403. Subsequently, the winch appropriately loosens the pull rope 2, and the gravity load of the support platform 3 is transferred to the V-shaped clamping frame 402 through the cylindrical base 401, and then to the building body through the connecting rod 403, hinge shaft 405, bearing frame 413 and support mechanism 5. At this time, the arc-shaped base frame 404 effectively shares the load of the connecting rod 403, reduces the bending deformation caused by the excessive cantilever, and significantly reduces the swaying and sinking amplitude of the support platform 3 during material loading and unloading.

[0028] After unloading, the operator manually pushes the arc-shaped base 404 back into the arc-shaped groove 406, then starts the motor 412 to rotate in the opposite direction, driving the two connecting rods 403 to rotate outward synchronously. The V-shaped clamp 402 disengages from the cylindrical base 401, and the lateral dimension of the stabilizing mechanism 4 is reduced, making it easier to disassemble and transfer.

[0029] Reference Figure 3 and Figure 4 In a preferred embodiment, the support mechanism 5 is used to install the stabilizing mechanism 4 onto the building sub-frame. The U-shaped frame 501 is movably snapped onto the lower edge of the sub-frame. A plurality of screw holes 508 are provided on one inner wall of the U-shaped frame 501, and a limiting screw 509 is movably engaged in each screw hole 508. A support frame 507 is fixedly connected to the outer wall of the top end of the U-shaped frame 501.

[0030] A snap-fit ​​groove 506 is fixed to the outer wall of the top of the support frame 507. The square base 502 is movably snapped into the snap-fit ​​groove 506. Of the two threaded tubes 503, the bottom end of the lower threaded tube 503 is fixedly connected to the outer wall of the top of the square base 502. A top plate 505 is fixedly connected to the outer wall of the top of the upper threaded tube 503. The two ends of the double-ended screw 504 are respectively engaged in the two threaded tubes 503, and the thread directions of the two ends of the double-ended screw 504 are opposite.

[0031] A slide groove 510 is provided on one inner wall of the U-shaped frame 501. The sliding frame 512 is movably engaged in the slide groove 510. One end of multiple springs 511 is fixedly connected to the outer wall of the top of the sliding frame 512, and the other end is fixedly connected to the inner wall of the top of the slide groove 510. Multiple rollers 513 are simultaneously rotatably connected to the inner walls of opposite sides of the sliding frame 512.

[0032] During installation, the operator attaches the U-shaped frame 501 to the lower edge of the sub-frame from top to bottom. Under the elastic force of the spring 511, the roller 513 is pushed outward, maintaining elastic rolling contact with the surface of the sub-frame, allowing the stabilizing mechanism 4 to move freely along the horizontal direction of the sub-frame.

[0033] Once the lateral position is adjusted to the correct position, the operator rotates multiple limit screws 509, and the ends of the limit screws 509 tightly abut against the side of the sub-frame, fixing the U-shaped frame 501 to the sub-frame in the horizontal direction.

[0034] Subsequently, the operator inserts the square base 502 into the snap-fit ​​groove 506, making the lower screw tube 503 detachably connected to the U-shaped frame 501. Rotating the double-ended screw 504 causes the two screw tubes 503 to move in opposite directions simultaneously due to the opposite thread directions at both ends, increasing their total length. The upper screw tube 503 then moves the top plate 505 upwards until the top plate 505 firmly abuts against the inner wall of the sub-frame top.

[0035] During this process, the U-shaped frame 501 is subjected to a downward reaction force, which is transmitted to the entire U-shaped frame 501 through the support frame 507, the snap-fit ​​groove 506, the square base 502, and the screw tube 503 below. The downward force is transmitted to the sliding frame 512, compressing the spring 511, causing the sliding frame 512 to drive the roller 513 to retract upward along the slide groove 510. After the spring 511 is fully compressed, the roller 513 is submerged in the slide groove 510, and the inner sidewall of the U-shaped frame 501 directly abuts against the surface of the lower edge of the sub-frame, achieving a bidirectional fixation of "bottom snap and top push".

[0036] Reference Figure 5 In a preferred embodiment, the auxiliary positioning mechanism 6 is used to ensure that the support mechanism 5 is precisely aligned with the position of the pull rope 2 during installation. The snap-fit ​​groove 601 is fixedly connected to the outer periphery of the lower screw tube 503. One end of the hinge seat 603 is movably snapped into the snap-fit ​​groove 601, and the snap-fit ​​surface of the hinge seat 603 is fixedly wrapped with a damping sleeve 602.

[0037] Hinge shaft 605 is rotatably connected within hinge base 603. Extension plate 606 is fixedly connected to the outer wall of one side of hinge shaft 605. One end of torsion spring 607 is connected to the bottom end of hinge base 603, and the other end is connected to hinge shaft 605, causing extension plate 606 to deflect outward in its natural state. Pointer 604 is fixedly connected to the top of hinge shaft 605, and mark 608 is set on the outer wall of the top of hinge base 603.

[0038] Before installation, the operator installs the hanger 1 on the top of the building, and the pull rope 2 hangs down after passing over the pulley on the hanger 1. The winch is started to keep the pull rope 2 taut and vertical. At this time, the position of the pull rope 2 is the ideal lifting trajectory line.

[0039] The operator attaches the U-shaped frame 501 to the sub-frame and uses the roller 513 to move the support mechanism 5 laterally to the vicinity of the pull rope 2. During this process, the extension plate 606 is kept deflected outward under the action of the torsion spring 607, and its end contacts the tensioned pull rope 2.

[0040] As the operator continues to move the support mechanism 5 laterally, the pull rope 2 applies a continuous lateral thrust to the extension plate 606, overcoming the elastic torque of the torsion spring 607, forcing the extension plate 606 to rotate inward around the second hinge shaft 605. The rotation of the extension plate 606 causes the second hinge shaft 605 to rotate synchronously, and the pointer 604 rotates accordingly.

[0041] The operator continuously moves the support mechanism 5 horizontally and observes the relative position of the pointer 604 and the mark 608. When the pointer 604 rotates to completely coincide with the mark 608, it indicates that the extension plate 606 has rotated to the preset target angle. At this time, the support mechanism 5 and the stabilizing mechanism 4 on it are directly below the pull rope 2, and the vertical projection line of the pull rope 2 coincides with the central axis of the cylindrical base 401.

[0042] The operator then tightens the limit screw 509 to fix the support mechanism 5 in the horizontal direction, and then rotates the double-headed screw 504 to make the top plate 505 press against the inner wall of the top of the sub-frame to complete the final fixation.

[0043] Since the auxiliary positioning mechanism 6 has ensured that the pull rope 2 is aligned with the center of the column base 401 during the installation process, when the support platform 3 rises to the floor, the column base 401 accurately enters the area between the two V-shaped clamps 402. When the V-shaped clamps 402 close, they can clamp the column base 401 evenly and symmetrically, achieving precise centering.

[0044] Working principle: Fix the hanger 1 to the top of the building. The pull rope 2 hangs down after passing over the hanger 1, with one end connected to a winch and the other end connected to the support platform 3. Start the winch to keep the pull rope 2 vertically taut; the position of the pull rope 2 at this point is the ideal trajectory line for material lifting. Secure the U-shaped frame 501 to the lower frame of the sub-frame of the target floor. Use the rollers 513 to move the entire support mechanism 5 laterally along the sub-frame.

[0045] During the translation process, the extension plate 606 of the auxiliary positioning mechanism 6 contacts the tensioned pull rope 2, and the pull rope 2 pushes the extension plate 606 to rotate inward. When the pointer 604 coincides with the mark 608, it indicates that the support mechanism 5 is directly below the pull rope 2, and the locking limit screw 509 completes the horizontal fixation. Then, the double-headed screw 504 is rotated, so that the top plate 505 presses upward against the inner wall of the top of the sub-frame, while the inner wall of the U-shaped frame 501 presses downward against the lower edge of the sub-frame, realizing a "bottom clamping and top pushing" bidirectional fixation.

[0046] The winch drives the support platform 3 to rise via the pull rope 2. When the support platform 3 reaches the target floor, the motor 412 is started. The motor 412 drives the two connecting rods 403 to rotate synchronously inward through the gear 410, the synchronous pulley 411, and the synchronous belt 409. The two V-shaped clamping frames 402 then close inward. The inner surface of the V-shaped clamping frame 402 is a V-shaped slope. During the clamping of the cylindrical base 401, even if the support platform 3 has a horizontal deviation, the V-shaped slope will force the cylindrical base 401 to automatically slide to the center position, realizing automatic centering and correction of the support platform 3.

[0047] After the V-shaped clamping frame 402 initially clamps the cylindrical base 401, the operator manually pulls the arc-shaped base frame 404 outward from the arc-shaped groove 406, so that its top end abuts against the bottom of the connecting rod 403, providing auxiliary rigid support for the connecting rod 403. Then, the winch appropriately loosens the pull rope 2, and the gravity load of the support platform 3 is transferred to the building body through the cylindrical base 401, V-shaped clamping frame 402, connecting rod 403, and bearing frame 413. At this time, the swaying and sinking of the support platform 3 are significantly reduced, and the operator can safely unload the material.

[0048] After unloading, the operator manually pushes the arc-shaped base frame 404 back into the arc-shaped groove 406, starts the motor 412 to rotate in the opposite direction, and the two connecting rods 403 open outwards simultaneously, causing the V-shaped clamping frame 402 to disengage from the cylindrical base 401. The winch re-tensions the pull rope 2 and lifts the support platform 3. The limit screw 509 and the double-ended screw 504 are released, and the entire support mechanism 5 is removed from the sub-frame and transferred to other floors for reuse.

[0049] The above description is only a preferred embodiment of the present invention, but the scope of protection of the present invention is not limited thereto. Any equivalent substitutions or modifications made by those skilled in the art within the scope of the technology disclosed in the present invention, based on the technical solution and inventive concept of the present invention, should be covered within the scope of protection of the present invention.
