Description

Technical Field

[0001] This invention relates to the field of scaffolding technology, and more particularly to an adjustable-height construction scaffolding. Background Technology

[0002] In the fields of building construction, equipment installation, and high-altitude operations, adjustable-height support devices such as scaffolding and work platforms are important tools to ensure construction efficiency and safety.

[0003] Traditional support devices rely heavily on bolt tightening, pin positioning, or multi-stage telescopic sleeves for height adjustment. This process is cumbersome and makes precise height control difficult. For example, some devices require simultaneous adjustment of multiple support legs, resulting in complex and time-consuming operations. Devices using telescopic sleeves have adjustment ranges limited by the length of the sleeve segments, failing to meet the needs of non-standard height operations. Currently, most support devices lack independent safety protection structures separate from the adjustment mechanism. When adjustment components such as threaded rods or connecting rods fail due to wear from long-term use or accidental impact, the support legs may suddenly separate, causing the installation platform to fall. For instance, some devices rely solely on the locking force of the adjustment mechanism to maintain height, lacking redundant safety design. Devices using safety belts or ropes for auxiliary fixation have insufficient connection strength between their protective structures and the support legs, failing to effectively prevent support leg separation in emergencies. Summary of the Invention

[0004] The purpose of this invention is to address the problems existing in the prior art by proposing an adjustable-height building scaffold that can be easily adjusted in height and prevents the legs from separating after the adjustment components fail.

[0005] The technical solution of the present invention: an adjustable-height construction scaffold, comprising, The mounting assembly includes two vertical rods, multiple horizontal rods connecting the vertical rods, and a plate disposed on the vertical rods and horizontal rods, wherein the vertical rods are provided with snap-fit ​​grooves; Two outrigger assemblies, each outrigger assembly including a connecting rod, a first support leg disposed on the connecting rod, a second support leg rotatably connected to the connecting rod via a connecting shaft, and a reinforcing rod connecting the first support leg and the second support leg, wherein the connecting rod is snapped into the snap-fit ​​groove; The support assembly includes a connecting rod rotatably connected to the reinforcing rod and the lifting plate at both ends, and a guide frame rotatably connected to the connecting rod, wherein the lifting plate is slidably disposed on the guide frame; The adjustment assembly includes a threaded rod rotatably mounted on the guide frame and a handle connected to the threaded rod. The threaded rod is threadedly connected to the lifting plate for driving the lifting plate to move along the guide frame; and... Protective components.

[0006] Preferably, the guide frame includes a connecting sleeve rotatably connected to the connecting rod, a guide rail disposed on the connecting sleeve, and a support rod fixed to the guide rail, the lifting plate being slidably disposed on the guide rail, and the threaded rod being rotatably disposed on the support rod.

[0007] Preferably, the adjustment assembly further includes a support sleeve, the upper end of which has an arc-shaped structure and abuts against the connecting rod, and the lower end is rotatably connected to the upper end of the threaded rod.

[0008] Preferably, the protective assembly includes a connecting cable disposed on the reinforcing rod, a chain connected to the connecting cable, an open cable, and a locking buckle, wherein the chain is detachably connected to the open cable via the locking buckle.

[0009] Preferably, in the protective assembly, the two connecting cables are respectively disposed on the reinforcing rods of the two outrigger assemblies, one end of the chain is fixedly connected to one of the connecting cables, the open cable is disposed on the other connecting cable, and the locking buckle is used to lock the connection between the open cable and the chain.

[0010] Preferably, the first support leg is fixedly mounted on the connecting rod, and the second support leg is rotatably connected to the connecting rod via the connecting shaft to adjust the angle between the first support leg and the second support leg. The angle is negatively correlated with the height of the connecting rod.

[0011] Preferably, the arc-shaped structure of the support sleeve fits against the outer circumferential surface of the connecting rod, the lower end of the support sleeve is provided with a bearing, and the upper end of the threaded rod is rotatably connected to the support sleeve through the bearing.

[0012] Compared with the prior art, the present invention has the following beneficial technical effects: In this invention, the mounting component is secured to two support leg components, which support the mounting component. By adjusting the tilt angle of support leg one and support leg two on the support leg components, the height of the connecting rod can be adjusted, thereby achieving height adjustment. This allows the mounting component to adjust its height. The support components support support leg one and support leg two, and the adjustment component drives the support components to move, thereby adjusting the angle between support leg one and support leg two. The smaller the angle, the higher the height of the connecting rod, and the greater the angle. After the height of the connecting rod is adjusted, a protective component is used to prevent support leg one and support leg two from separating due to accidents, thus facilitating the sudden fall of the mounting component.

[0013] The mounting components include vertical bars, horizontal bars, and a plate. There are two vertical bars and multiple horizontal bars for connecting the two vertical bars. The plate is mounted on the vertical bars and horizontal bars. The vertical bars are provided with snap-fit ​​grooves that can snap onto the connecting bars.

[0014] The outrigger assembly includes a connecting rod, two support legs (first type) mounted on the connecting rod, two connecting shafts mounted on the connecting rod, a second support leg (second type) rotatably mounted on the connecting shafts, and two reinforcing rods respectively mounted on the first and second support legs. This allows the second support leg to rotate with the connecting rod via the connecting shafts, while the first support leg is mounted on the connecting rod, thus changing the angle between the first and second support legs. This allows for adjustment of the height of the connecting rod, which can be engaged in a locking groove. The two outrigger assemblies provide stable support for the installation assembly, allowing a person to stand on the installation assembly for construction work.

[0015] The support assembly includes two connecting rods, one end of which is rotatably mounted on a reinforcing rod. A guide frame is rotatably mounted on the mounting assembly, and a lifting plate is slidably mounted on the guide frame. The connecting rods are rotatably mounted on the lifting plate. An adjustment assembly drives the lifting plate to move up and down, which in turn moves the connecting rods, thereby moving support legs one and two, allowing adjustment of the angle between support legs one and two, and thus adjusting the height of the connecting rod. The guide frame includes a connecting sleeve, a guide rail, and a support rod. Two connecting sleeves and guide rails are rotatably mounted on the connecting rod for connecting the rod. The guide rail is mounted on the connecting sleeve, and the support rod is mounted on the guide rail. The lifting plate is slidably mounted on the guide rail. The guide rail supports and guides the lifting plate, and the support rod is used to mount the adjustment assembly.

[0016] The adjustment assembly includes a threaded rod, a handle, and a support sleeve. The threaded rod rotates on the support rod and can be threadedly connected to the lifting plate, thereby driving the lifting plate to move up and down. The handle is located at the lower end of the threaded rod, so as to facilitate the rotation of the threaded rod. The support sleeve is rotatably connected to the upper end of the threaded rod. The upper part of the support sleeve has an arc-shaped structure. The support sleeve abuts against the connecting rod, so as to be locked on the connecting rod and support the threaded rod.

[0017] The protective assembly includes connecting cables, a chain, an open cable, and a locking buckle. Two connecting cables are respectively mounted on two reinforcing rods. One end of the chain is connected to one of the connecting cables, and the open cable is mounted on the other. When the locking buckle is opened, the open cable engages with the chain. Closing the locking buckle then connects the chain to the connecting cables via the open cable. This protective assembly provides limiting support between the two reinforcing rods. If the support or adjustment assembly is damaged or fails, the chain will support the two reinforcing rods, preventing support leg one and support leg two from separating, thus ensuring stability and preventing falls.

[0025] like Figure 1-6 As shown, the present invention proposes an adjustable-height construction scaffold, comprising, The mounting assembly 1 includes two vertical rods 101, multiple horizontal rods 102 connecting the vertical rods 101, and a plate 103 disposed on the vertical rods 101 and the horizontal rods 102. The vertical rods 101 are provided with snap-fit ​​grooves 1011. Two outrigger assemblies 2, each outrigger assembly 2 includes a connecting rod 201, a first support leg 202 disposed on the connecting rod 201, a second support leg 203 rotatably connected to the connecting rod 201 via a connecting shaft 204, and a reinforcing rod 205 connecting the first support leg 202 and the second support leg 203, the connecting rod 201 being snapped into a snap-fit ​​groove 1011; The support assembly 3 includes a connecting rod 301 that is rotatably connected to the reinforcing rod 205 and the lifting plate 302 at both ends, and a guide frame 303 that is rotatably connected to the connecting rod 201. The lifting plate 302 is slidably mounted on the guide frame 303. Adjustment assembly 4 includes a threaded rod 401 rotatably mounted on the guide frame 303, and a handle 402 connected to the threaded rod 401. The threaded rod 401 is threadedly connected to the lifting plate 302 for driving the lifting plate 302 to move along the guide frame 303; and... Protective component 5.

[0026] Furthermore, the guide frame 303 includes a connecting sleeve 3031 rotatably connected to the connecting rod 201, a guide rail 3032 disposed on the connecting sleeve 3031, and a support rod 3033 fixed to the guide rail 3032. The lifting plate 302 is slidably disposed on the guide rail 3032, and the threaded rod 401 is rotatably disposed on the support rod 3033.

[0027] Furthermore, the adjustment component 4 also includes a support sleeve 403, the upper end of which has an arc-shaped structure and abuts against the connecting rod 201, and the lower end is rotatably connected to the upper end of the threaded rod 401.

[0028] Furthermore, support leg one 202 is fixedly mounted on connecting rod 201, and support leg two 203 is rotatably connected to connecting rod 201 via connecting shaft 204, so as to adjust the included angle between support leg one 202 and support leg two 203. The included angle is negatively correlated with the height of connecting rod 201.

[0029] Furthermore, the arc-shaped structure of the support sleeve 403 fits against the outer circumferential surface of the connecting rod 201, and the lower end of the support sleeve 403 is provided with a bearing, and the upper end of the threaded rod 401 is rotatably connected to the support sleeve 403 through the bearing.

[0030] In this embodiment, the mounting component 1 is attached to two support leg components 2, which support the mounting component 1. By adjusting the tilt angle of the first support leg 202 and the second support leg 203 on the support leg component 2, the height of the connecting rod 201 can be adjusted, thereby achieving height adjustment and driving the mounting component 1 to adjust its height. The support component 3 supports the first support leg 202 and the second support leg 203, and the adjustment component 4 drives the support component 3 to move, thereby adjusting the included angle between the first support leg 202 and the second support leg 203. The smaller the angle, the higher the height of the connecting rod 201, and vice versa. After the height of the connecting rod 201 is adjusted, the protective component 5 is used to protect it from accidental separation of the first support leg 202 and the second support leg 203, thus facilitating the sudden fall of the mounting component 1.

[0031] Mounting assembly 1 includes a vertical rod 101, a horizontal rod 102, and a plate 103. There are two vertical rods 101, and multiple horizontal rods 102 are provided for connecting the two vertical rods 101. The plate 103 is provided on the vertical rods 101 and the horizontal rods 102. The vertical rods 101 are provided with snap-fit ​​grooves 1011, which can snap onto the connecting rod 201.

[0032] The outrigger assembly 2 includes a connecting rod 201, two support legs 202 mounted on the connecting rod 201, two connecting shafts 204 mounted on the connecting rod 201, a second support leg 203 rotatably mounted on the connecting shafts 204, and two reinforcing rods 205 mounted on the first support leg 202 and the second support leg 203 respectively. This allows the second support leg 203 to rotate with the connecting rod 201 via the connecting shafts 204, while the first support leg 202 is mounted on the connecting rod 201. This allows the angle between the first support leg 202 and the second support leg 203 to change, thereby adjusting the height of the connecting rod 201. The connecting rod 201 can be locked in the locking groove 1011. The two outrigger assemblies 2 provide stable support for the installation assembly 1, allowing a person to stand on the installation assembly 1 for construction work.

[0033] Support assembly 3 includes two connecting rods 301, one end of which is rotatably mounted on reinforcing rod 205. A guide frame 303 is rotatably mounted on mounting assembly 1, and a lifting plate 302 is slidably mounted on the guide frame 303. Connecting rods 301 are rotatably mounted on the lifting plate 302. The lifting plate 302 is driven to move up and down by adjusting assembly 4. The lifting plate 302 drives the connecting rods 301 to move, thereby moving support leg one 202 and support leg two 203, thus adjusting the angle between support leg one 202 and support leg two 203. The height of the connecting rod 201 can be adjusted; the guide frame 303 includes a connecting sleeve 3031, a guide rail 3032, and a support rod 3033; the connecting sleeve 3031 and the guide rail 3032 are both rotatably mounted on the connecting rod 201 for connecting the connecting rod 201, the guide rail 3032 is mounted on the connecting sleeve 3031, the support rod 3033 is mounted on the guide rail 3032, the lifting plate 302 is slidably mounted on the guide rail 3032, the guide rail 3032 is used to support and guide the lifting plate 302, and the support rod 3033 is used to install the adjustment component 4.

[0034] The adjusting assembly 4 includes a threaded rod 401, a handle 402, and a support sleeve 403. The threaded rod 401 rotates on the support rod 3033 and can be threadedly connected to the lifting plate 302, thereby driving the lifting plate 302 to move up and down. The handle 402 is located at the lower end of the threaded rod 401, so that the threaded rod 401 can be rotated easily. The support sleeve 403 is rotatably connected to the upper end of the threaded rod 401. The upper part of the support sleeve 403 has an arc-shaped structure. The support sleeve 403 abuts against the connecting rod 201, so that it can be locked on the connecting rod 201 and support the threaded rod 401.

[0035] Rotating the handle 402 of the adjusting assembly 4 drives the threaded rod 401 to rotate. The threaded engagement between the threaded rod 401 and the lifting plate 302 allows for precise control of the lifting plate 302's displacement. This, in turn, allows for synchronous adjustment of the angle between support leg 1 202 and support leg 203 via the connecting rod 301. This design establishes a linear relationship between angle change and height adjustment. The smaller the angle, the higher the connecting rod 201. Operators can quickly grasp the adjustment accuracy through intuitive angle feedback, avoiding the tedious process of repeated adjustments required by traditional devices and improving construction efficiency by more than 30%.

[0036] Stepless continuous adjustment: The cooperation between the threaded rod 401 and the guide rail 3032 enables stepless height adjustment, breaking through the limitations of traditional segmented adjustment of the sleeve. It can adapt to any height requirement within the range of 0.5m to 2.5m, and is especially suitable for work scenarios with non-standard floor heights. Example 2

[0037] like Figure 1-6As shown, the present invention proposes an adjustable height building scaffold. Compared with Embodiment 1, the protective component 5 in this embodiment includes a connecting cable 501 disposed on the reinforcing rod 205, a chain 502 connected to the connecting cable 501, an open cable 503 and a locking buckle 504. The chain 502 is detachably connected to the open cable 503 through the locking buckle 504.

[0038] Furthermore, in the protective component 5, two connecting cables 501 are respectively set on the reinforcing rods 205 of the two outrigger components 2, one end of the chain 502 is fixedly connected to one of the connecting cables 501, the open cable 503 is set on the other connecting cable 501, and the locking buckle 504 is used to lock the connection between the open cable 503 and the chain 502.

[0039] In this embodiment, the protective component 5 includes a connecting cable 501, a chain 502, an open cable 503, and a locking buckle 504. The two connecting cables 501 are respectively mounted on the two reinforcing rods 205. One end of the chain 502 is connected to one of the connecting cables 501, and the open cable 503 is mounted on the other connecting cable 501. When the locking buckle 504 is opened, the open cable 503 can be inserted into the chain 502. When the locking buckle 504 is closed, the chain 502 is connected to the connecting cable 501 through the open cable 503. The two reinforcing rods 205 are limited and supported by the protective component 5. When the support component 3 or the adjustment component 4 is damaged or fails, the chain 502 can support the two reinforcing rods 205 to prevent the support leg 1 202 and the support leg 2 203 from separating, thereby ensuring stability and preventing a fall.

[0040] The embodiments of the present invention have been described in detail above with reference to the accompanying drawings. However, the present invention is not limited thereto. Various changes can be made within the scope of knowledge possessed by those skilled in the art without departing from the spirit of the present invention.
