Description

Technical Field

[0001] This utility model relates to the field of hoisting equipment technology, and in particular to a building wall hoisting equipment. Background Technology

[0002] When hoisting building walls, the main equipment used is hoisting equipment. Building wall hoisting equipment refers to mechanical equipment specifically designed for the efficient and precise hoisting and installation of prefabricated wall components during construction. Commonly used hoisting tools include hooks, lifting rings, lifting plates, slings, wire ropes, chains, and lifting suction cups. Currently, hoisting structures often use lifting rings directly connected to pull rings at the top of the wall via wire ropes or chains, or symmetrically spaced through-holes on the upper side of the wall to connect to lifting lugs symmetrically fixed at the top center of the lifting plate. In the construction of prefabricated buildings, hoisting devices are used to lift the wall above pre-embedded reinforcing bars. The angle of the wall is then adjusted so that the pre-drilled holes on the wall align with the reinforcing bars, and the wall is lowered so that the reinforcing bars are precisely inserted into the pre-drilled holes.

[0003] However, in the implementation of existing wall hoisting devices, because the embedded steel bars and the wall are relatively high, the wall is prone to swaying when hoisted above the embedded steel bars. When aligning the reserved holes on the wall with the steel bars, it is necessary to manually hold the wall and adjust its deflection angle and horizontal position to align the reserved holes on the bottom of the wall with the reserved steel bars on the floor slab. At this time, it is difficult for the workers below to observe the alignment of the steel bars with the reserved holes, making calibration very difficult. Manual adjustment is time-consuming, labor-intensive, and dangerous, requiring multiple people to cooperate, which increases labor costs. The alignment and positioning operation is very troublesome, affecting installation efficiency and safety. Utility Model Content

[0004] In order to overcome the shortcomings of the existing technology, the purpose of this utility model is to provide a building wall hoisting device that can more conveniently position the reserved holes on the bottom surface of the wall and the pre-embedded steel bars on the floor slab.

[0005] The objective of this utility model is achieved through the following technical solution:

[0006] A building wall hoisting device, characterized in that it comprises:

[0007] A hanging board, used to suspend the wall to be moved and connected;

[0008] A lifting drive mechanism, comprising a base and an output section, wherein the base is mounted on the suspended plate and the output section is connected to the base;

[0009] A positioning robotic arm is hinged to and supported by the output unit, and is capable of horizontally swinging relative to the output unit; the positioning robotic arm is provided with a guide hole for inserting a positioning reinforcing bar.

[0010] Furthermore, a positioning claw disk is provided at one end of the positioning robotic arm away from the output part. The positioning claw disk has multiple positioning claws, which are arranged sequentially around the circumference of the positioning claw disk and form the guide hole.

[0011] Furthermore, the positioning claw is movably connected to the positioning claw disk so that it can move radially along the positioning claw disk to grip or release the positioning steel bar.

[0012] Furthermore, the positioning robotic arm is equipped with a first motor, which is connected to the positioning claw via a transmission assembly.

[0013] Furthermore, the robotic arm includes a support base and a sliding base. The support base is hinged to and supported by the output unit. The support base has a horizontal extension cavity. The sliding base is slidably connected to the support base so that it can retract into the horizontal extension cavity of the support base or slide out of the horizontal extension cavity to the outside of the support base. The first motor is mounted on the sliding base.

[0014] Furthermore, the sliding seat is equipped with a second motor, and the support seat is provided with a rack. The second motor is connected to the rack via gears to drive the sliding seat to slide relative to the support seat.

[0015] Furthermore, the support base is provided with a guide block, and the sliding base is provided with a guide groove. The guide groove extends along the extension direction of the sliding base, and the guide block and the guide groove are movably engaged.

[0016] Furthermore, the output section is connected to a sphere, and the support base is provided with a spherical groove that is spherically hinged to the sphere; the inner cavity of the support base is connected to the spherical groove, and the support base is pivotally connected to a knob, which is connected to a driving helical gear located in the inner cavity of the support base and a driven helical gear located in the inner cavity of the support base; the driven helical gear is connected to a rotary rod, and the rotary rod is threadedly fitted with a horizontal clamping rod, which can squeeze the sphere or release the squeeze on the sphere.

[0017] Furthermore, the hanging platform is equipped with a horizontal drive mechanism, and the output of the horizontal drive mechanism is connected to the seat body in a transmission manner.

[0018] Furthermore, the suspended platform is provided with multiple lifting lugs, which are used to connect to bolts that pass through the wall; multiple steel cables are connected to the top of the suspended platform, and the tops of the multiple steel cables are connected together and connected to a lifting ring.

[0019] Compared with the prior art, the beneficial effects of this utility model are as follows:

[0020] 1. The hanging platform is used to suspend the wall to be moved and connected, so that the wall has a stable load-bearing foundation during hoisting and subsequent precise positioning.

[0021] 2. The lifting drive mechanism includes a base and an output section. The base is mounted on the hanging plate, and the output section is connected to the base, so that the positioning robotic arm can be precisely adjusted in the vertical direction.

[0023] 4. The positioning robotic arm is equipped with a guide hole for inserting positioning steel bars; this allows the positioning robotic arm to achieve initial alignment with the positioning steel bars and guides the reserved hole at the bottom of the wall to accurately insert the steel bars into the pre-embedded steel bars on the floor slab, greatly improving the insertion accuracy and construction efficiency, and significantly reducing the need for manual adjustment and the difficulty of operation.

[0033] Unless otherwise defined, all technical and scientific terms used herein have the same meaning as commonly understood by one of ordinary skill in the art to which this invention pertains. The terminology used herein in the specification of the invention is for the purpose of describing particular embodiments only and is not intended to be limiting of the invention. The term "and / or" as used herein includes any and all combinations of one or more of the associated listed items.

[0034] See Figures 1-6 The present invention relates to a building wall hoisting device, comprising: a hoisting plate 1, a lifting drive mechanism 7, and a positioning robotic arm 2.

[0035] The hanging plate 1 is used to suspend the wall 10 to be moved and connected;

[0036] The lifting drive mechanism 7 includes a base 9 and an output part 71. The base 9 is mounted on the hanging plate 1, and the output part 71 is connected to the base 9.

[0037] The positioning robotic arm 2 is hinged to the output part 71 and supported by the output part 71, and can swing horizontally relative to the output part 71; the positioning robotic arm 2 is provided with a guide hole for the insertion of the positioning steel bar 14.

[0038] During operation, the operator first fixes the wall 10 to be installed onto the hanging plate 1, and installs two detachable positioning steel bars 14, which are shorter than the pre-embedded steel bars, onto the floor slab. Then, the lifting drive mechanism 7 is activated to lower the positioning robotic arm 2 to the area below the wall 10. By adjusting the joint posture of the positioning robotic arm 2, the guide hole of the positioning robotic arm 2 is precisely aligned with the reserved hole 101 on the bottom surface of the wall 10. After the wall 10 is hoisted to a position above the positioning steel bars 14, the lifting drive mechanism 7 is activated again to lower the positioning robotic arm 2 until the positioning steel bars 14 are aligned with the internal space of the guide hole. At this point, the hanging plate 1 can be lifted to lower the wall 10, so that the reserved hole 101 at the bottom of the wall 10 can be precisely inserted into the pre-embedded steel bars on the floor slab. The lifting drive mechanism 7 is then activated again to raise and retract the positioning robotic arm 2, allowing the wall 10 to descend until it is flush with the floor slab, completing the hoisting of the wall 10.

[0039] The hanging plate 1 is used to suspend the wall 10 to be moved and connected, so that the wall 10 has a stable load-bearing foundation during hoisting and subsequent precise positioning.

[0040] The lifting drive mechanism 7 includes a base 9 and an output part 71. The base 9 is mounted on the hanging plate 1, and the output part 71 is connected to the base 9, so that the positioning robotic arm 2 can be precisely adjusted in the vertical direction.

[0041] The positioning robotic arm 2 is hinged to the output unit 71 and supported by the output unit 71, and can swing horizontally relative to the output unit 71; this allows the positioning robotic arm 2 to adaptively adjust the horizontal rotation angle, achieving flexible control of multi-degree-of-freedom posture; at the same time, the hinge isolates the lifting motion from the arm swing, making the linear drive of the first telescopic device independent of the positioning robotic arm 2, reducing the control coupling complexity of the multi-degree-of-freedom system, and ensuring the rationality of the motion.

[0042] The positioning robotic arm 2 is equipped with a guide hole for inserting the positioning steel bar 14. This allows the positioning robotic arm 2 to achieve initial alignment with the positioning steel bar 14 and guides the reserved hole 101 at the bottom of the wall 10 to accurately insert into the pre-embedded steel bar on the floor slab, greatly improving the insertion accuracy and construction efficiency, and significantly reducing the need for manual adjustment and the difficulty of operation.

[0043] In this embodiment, preferably, a positioning claw disk 5 is provided at one end of the positioning robotic arm 2 away from the output part 71. The positioning claw disk 5 has multiple positioning claws 6, which are arranged sequentially around the circumference of the positioning claw disk 5 and form the guide hole. During operation, the multiple positioning claws 6 evenly distributed around the circumference of the positioning claw disk 5 together form the guide hole, forming a rigid physical guide channel. During the hoisting and lowering of the wall 10, the reserved hole 101 at the bottom of the wall 10 can be connected to the pre-embedded steel bar through the positioning steel bar 14. At the same time, the positioning claw disk 5 is initially aligned with the wall 10 through the guide hole and the reserved hole 101 at the bottom of the wall 10.

[0044] In this embodiment, preferably, the positioning claw 6 is movably connected to the positioning claw disk 5 so as to move radially along the positioning claw disk 5 to clamp or release the positioning steel bar 14; the circumferentially distributed positioning claws 6 constitute a synchronously adjustable group of positioning claws 6. Because the positioning claws 6 can move radially within the positioning claw disk 5, the positioning claw disk 5 can adapt to steel bars of different diameters, and the positioning accuracy is further improved by compensating for positioning errors through synchronous radial clamping. Simultaneously, the positioning robotic arms 2 symmetrically arranged on both sides of the hanging plate 1, after having a concentric clamping function, can achieve stable two-point positioning during operation.

[0045] In this embodiment, preferably, the radial inner end face of the positioning claw 6 may be provided with an elastic roller 61; the elastic roller 61 is preferably made of elastic materials such as rubber or polyurethane. The radial compressibility of the elastic roller 61 allows the positioning claw 6 group to automatically compensate for the position deviation of the reinforcing bar when synchronously radially clamping the pre-embedded reinforcing bar; at the same time, after the positioning reinforcing bar 14 is aligned with the internal space of the guide hole and the lifting plate 1 is lowered, the elastic roller 61 can convert the sliding friction between the claw and the reinforcing bar into rolling friction, which can prevent the reinforcing bar from directly scratching the metal claw, reduce the impact load on the joint of the robotic arm, and extend the service life of the equipment.

[0046] In this embodiment, preferably, the positioning robotic arm 2 is equipped with a first motor 404, which is connected to the positioning claw 6 via a transmission assembly. The transmission assembly is located inside the positioning claw disk 5 and includes a small bevel gear 401 and a transmission disk. One side of the transmission disk is a large bevel gear 401 that meshes with the small bevel gear 401, and the other side is a flat thread. The positioning claw 6 has a flat thread on the side that fits against the positioning chuck, which meshes with the threaded surface of the transmission disk. During operation, the first motor 404 drives the small bevel gear 401 to rotate, thereby driving the rotation of the transmission disk, ultimately realizing the radial movement of the positioning claw 6. By setting the first motor 404, the positioning claw 6 achieves automated clamping control of the positioning steel bar 14, reducing the need for manual adjustment.

[0047] In this embodiment, preferably, the robotic arm includes a support base 3 and a sliding base 4. The support base 3 is hinged to and supported by the output part 71, and the support base 3 has a horizontal extension cavity. The sliding base 4 is slidably connected to the support base 3, so that it can retract into the horizontal extension cavity of the support base 3 or slide out of the horizontal extension cavity to the outside of the support base 3. The first motor 404 is mounted on the sliding base 4. During operation, the sliding base 4 can slide and extend along the horizontal extension cavity of the support base 3, thereby increasing the horizontal movement freedom of the positioning robotic arm 2 and enabling the end-effector positioning claw 5 to have a wide range of position adjustment capabilities. The sliding base 4 also carries the first motor 404, ensuring that the clamping system of the positioning claw 5 moves synchronously with the extension and retraction, improving the flexibility of positioning the rebar. Preferably, the sliding seat 4 has a claw plate shell 41 at one end away from the support seat 3. The claw plate shell 41 has a cavity that can accommodate the positioning claw plate 5. The claw plate shell 41 has a slot for the positioning claw 6 to move radially. The claw plate and the claw plate shell 41 have through holes 51 that are the same size and shape as the guide hole. The claw plate shell 41 provides a precise assembly space for the positioning claw plate 5, and the cavity depth matches the thickness of the claw plate. At the same time, the chuck shell encloses the positioning claw plate 5, which can isolate external pollutants such as concrete debris and dust from entering during operation, ensuring that the positioning claw plate 5 can operate stably in the harsh environment of the construction site.

[0048] In this embodiment, preferably, the sliding seat 4 is equipped with a second motor 403, and the support seat 3 is provided with a rack 402. The second motor 403 is connected to the rack 402 via a gear 401 to drive the sliding seat 4 to slide relative to the support seat 3. Preferably, the second motor 403 is a servo motor. The gear 401 and rack 402 transmission, in conjunction with the servo motor control, ensures no slippage during the extension and retraction process. The gear 401 and rack 402 transmission enables fine adjustment of the claw plate position, thereby adapting to the positioning requirements of rebars at different distances and significantly improving operational convenience. During operation, the operator can control the extension and retraction of the sliding seat 4 by rotating the motor forward and backward, further improving the coaxial positioning between the guide hole of the positioning chuck on the positioning robotic arm 2 and the reserved hole 101 on the wall 10.

[0049] In this embodiment, preferably, the support base 3 is provided with a guide block 311, and the sliding base 4 is provided with a guide groove 411. The guide groove 411 extends along the extension direction of the sliding base 4, and the guide block 311 is movably engaged with the guide groove 411. The guide block 311 of the support base 3 is embedded in the guide groove 411 of the sliding base 4 to form a sliding pair. During operation, the sliding base 4 is constrained to slide only along the horizontal extension direction of the guide groove 411, eliminating the risk of swaying and ensuring the stability of the positioning claw disk 5 during horizontal movement.

[0050] In this embodiment, preferably, the output part 71 is connected to a sphere, and the support base 3 is provided with a spherical groove 321 that is spherically hinged to the sphere; the inner cavity 31 of the support base 3 is connected to the spherical groove 321; preferably, the support base 3 is provided with a cover 32, and the spherical groove 321 that is hinged to the sphere of the output part 71 is located on the cover 32. The hinge design between the sphere of the output part 71 and the spherical groove 321 adopts the spherical pair characteristics to further optimize the degree of freedom control of the positioning robot arm 2; the cover 32 is fixedly connected to the support base 3 to close the inner cavity 31 of the base, which can effectively protect the internal transmission components from the influence of pollutants at the construction site.

[0051] In this embodiment, preferably, the support base 3 is pivotally connected to a knob 305, which is connected to a driving helical gear 301401401 located in the inner cavity 31 of the base and a driven helical gear 302401401 located in the inner cavity 31 of the base; the driven helical gear 302401401 is connected to a rotary rod 303, one end of the rotary rod 303 is used to connect to the driven helical gear 302401401, and the end of the rotary rod 303 away from the driven helical gear 302401401 has an internal threaded hole, and a horizontal clamping rod 304 is threadedly sleeved on the rotary rod 303. The end of the horizontal clamping rod 304 away from the threaded rotating rod 303 is a smooth rod section. The smooth rod section of the horizontal clamping rod 304 can be used to compress the ball or release the compression of the ball. The support base 3 is fixedly installed with a helical gear 401 fixing plate and a rotating rod 303 fixing plate. The smooth rod section is provided with an axial keyway. The fixing hole of the rotating rod 303 fixing plate is provided with a flat key 308 that slides with the keyway. After the flat key 308 is embedded in the keyway, during operation, the rigid contact between the side wall of the keyway and the flat key 308 forms a circumferential constraint, which converts the rotational motion of the threaded push rod into axial linear displacement. In use, the operator adjusts the joints of the positioning robotic arm 2 to a suitable position, and after the guide hole of the positioning claw disk 5 is coaxially positioned with the reserved hole 101 at the bottom of the wall 10, the operator can turn the knob 305 to drive the driven helical gear 302401401 meshing with it through the rotation of the active helical gear 301401401, thereby driving the rotary rod 303 to rotate. Through the cooperation of the threaded pair and the flat key 308 and the keyway, the horizontal clamping rod 304 moves linearly along its axis. Based on the linear movement of the horizontal clamping rod 304, it can axially press the ball head of the ball head push rod, and achieve the locking function of the ball head through the pre-tightening force, thereby completing the joint locking of the positioning robotic arm 2 and finally achieving the initial alignment of the positioning robotic arm 2.

[0052] In this embodiment, preferably, the hanging plate 1 is equipped with a horizontal drive mechanism 8, and the output part 71 of the horizontal drive mechanism 8 is connected to the base 9 in a transmission connection. In use, the operator can drive the base 9 on both sides of the hanging plate 1 to reciprocate and extend through the horizontal drive mechanism 8, so as to flexibly adjust the overall length of the hanging plate 1 to meet the hoisting requirements of walls 10 of different sizes. At the same time, by adjusting the position of the positioning robotic arm 2, the through hole 51 of the positioning claw disk 5 can be further precisely aligned with the reserved hole 101 at the bottom of the wall 10, and the positioning robotic arm 2 can be more easily retrieved after positioning.

[0053] In this embodiment, preferably, the lifting plate 1 is provided with multiple lifting lugs 11, which are used to connect the screw rods 102 that pass through the wall 10. In use, the operator first aligns the fixing nuts 103 with both sides of the perforation at the top of the wall 10, then aligns the symmetrically positioned lifting lugs 11 at the center of the lifting plate 1 with the perforation at the top of the wall 10. Next, the screw rods 102 are passed sequentially through the lifting lugs 11, the perforation, and the fixing nuts 103 between them. Then, the fixing nuts 103 on both sides of the perforation are tightened, and fixing nuts 103 are symmetrically added to both ends of the screw rods 102 to lock the lifting lugs 11 in place, thus achieving a secure fixation between the lifting lugs 11 and the wall 10. Multiple steel cables are connected to the top of the lifting plate 1, and the tops of these steel cables are interconnected and connected to a lifting ring 13. Preferably, the steel cables are located on the four right-angled sides of the top of the lifting plate 1, which ensures that the lifting plate 1 is subjected to uniform force during use, thereby ensuring the balance and safety of the lifting process.
