Description

Technical Field

[0001] This utility model belongs to the field of building decoration, and specifically relates to a building smooth lifting device. Background Art

[0002] Architectural decoration, short for architectural decoration and renovation engineering, involves the comprehensive treatment of the interior and exterior surfaces and spaces of buildings using decorative materials and ornaments. The aim is to protect the main structure of the building, optimize its physical performance and functionality, and enhance its aesthetics. This process not only focuses on improving the building's practicality but also on beautifying its appearance. For high-rise building wall construction, such as painting or drilling, high-altitude operations rely on lifting equipment. Traditional lifting equipment typically consists of a base frame and a liftable platform, connected by a lifting rod assembly with a built-in drive source, allowing for height adjustment and facilitating worker operation from the platform.

[0003] Chinese patent CN219259496U describes a construction hoist, which includes: a base, with wheels below the base, and a lifting mechanism connecting the base to a support platform. The support platform has fixed guardrails on its front and rear sides, and a pair of support plates on its left and right sides. The support plates have openings, and movable guardrails are slidably installed in the openings. A locking mechanism is provided between the upper end of the movable guardrail and the fixed guardrail.

[0004] However, while such equipment is equipped with a protective frame to ensure safety, this design increases the size and weight of the equipment, making transportation and carrying inconvenient.

[0005] Therefore, it is necessary to provide a building smooth lifting device to solve the problems mentioned in the background art. Utility Model Content

[0007] One end of the lifting mechanism is mounted on the base, and the other end is mounted on the lifting base plate. The lifting mechanism is used to adjust the height of the lifting base plate.

[0008] Two guardrails are symmetrically installed on both sides of the lifting base plate to provide safety protection; the adjustment mechanism is installed on the lifting base plate and connected to one end of the guardrail, and works with the lifting mechanism to expand and retract the guardrail.

[0009] Specifically, the adjustment mechanism includes: a linkage rod, two locking components, an electric telescopic rod, and two U-shaped locking rods;

[0010] One side of the linkage rod is rotatably connected to the guardrail, and the other side is fixed with the U-shaped locking rod at its end; the two locking components are fixed to the lifting base plate corresponding to the U-shaped locking rod, and are used to lock the U-shaped locking rod under specific conditions;

[0015] A compression spring, one end of which is fixed to the slider, and the other end of which is fixed to the lifting base plate;

[0016] The guide rope is connected at one end to the slider and at the other end to the slide cylinder.

[0017] As a further improvement of this utility model, a limiting block is provided on the slide cylinder, and the limiting block limits the rotation direction of the stop rod.

[0018] As a further improvement of this utility model, the lifting base plate includes: a bearing plate, two placement slots, a rotating shaft, and a guide rail;

[0019] The support plate is mounted on the lifting mechanism, and a guide rail is fixed at the bottom of the support plate. The slider is slidably mounted on the guide rail.

After the first support rod, the second support rod and the adjusting sleeve are stored, they will be completely placed in the placement groove 32 for protection to prevent damage during transportation and handling.

[0041] See Figures 1 to 6 As shown, a building smooth lifting device is characterized by comprising: a base 1, a lifting mechanism 2, a lifting base plate 3, two guardrails 4, and an adjusting mechanism 5.

[0042] One end of the lifting mechanism 2 is mounted on the base 1, and the other end is mounted on the lifting base plate 3. The lifting mechanism 2 is used to adjust the height of the lifting base plate 3.

[0043] Two guardrails 4 are symmetrically installed on both sides of the lifting base plate 3 to provide safety protection; the adjustment mechanism 5 is installed on the lifting base plate 3 and connected to one end of the guardrail 4, and works with the lifting mechanism 2 to expand and retract the guardrail 4;

[0044] Specifically, the adjustment mechanism 5 includes: a linkage rod 51, two locking components 52, an electric telescopic rod 53, and two U-shaped locking rods 54;

[0045] One side of the linkage rod 51 is rotatably connected to the guardrail 4, and the other side is fixed with the U-shaped locking rod 54 at its end; the two locking components 52 are fixed on the lifting base plate 3 corresponding to the U-shaped locking rod 54, and are used to lock the U-shaped locking rod 54 under specific conditions;

[0046] One end of the electric telescopic rod 53 is rotatably mounted on the lifting base plate 3, and the other end is rotatably connected to the U-shaped locking rod 54.

[0047] When high-altitude construction work is required, the lifting mechanism 2 adjusts the lifting platform 3 to the appropriate working height. When the lifting mechanism 2 raises the lifting platform 3 above the safe height, it simultaneously releases the locking component 52, activating the electric telescopic rod 53 to pull the U-shaped locking rod 54, thus placing the U-shaped locking rod 54 within the locking component 52. The locking component 52 then locks the U-shaped locking rod 54, and the electric telescopic rod 53 stops. Simultaneously, as the U-shaped locking rod 54 moves, the linkage rod 51 pulls the guardrail 4, causing it to unfold from within the lifting platform 3, providing safety protection for construction workers and preventing accidental falls.

[0048] When the lifting device is stored after the high-altitude operation is completed, the lifting mechanism 2 pushes the locking component 52 during the retraction process, thereby releasing the locking component 52 from restricting the U-shaped locking rod 54. That is, under the action of the guardrail 4, the U-shaped locking rod 54 is restored to its initial state through the linkage rod 51.

[0049] In summary, by linking the lifting mechanism 2, the adjusting mechanism 5, and the guardrail 4, the guardrail 4 can be quickly deployed and stored, which improves building safety while reducing the storage space required for the device.

[0050] like Figure 3 As shown, in a preferred embodiment, the locking component 52 includes:

[0051] The housing 521 is fixed on the lifting base plate 3, and a slide cylinder 524 is slidably provided on the side near the linkage rod 51, and a stop bar 525 is rotatably provided on the slide cylinder 524;

[0052] Slider 522 is slidably mounted on the lifting base plate 3;

[0053] The compression spring 523 has one end fixed to the slider 522 and the other end fixed to the lifting base plate 3;

[0054] The guide rope is connected at one end to the slider 522 and at the other end to the slide cylinder 524.

[0055] In a preferred embodiment, a limiting block is provided on the slide 524, and the limiting block limits the rotation direction of the stop 525.

[0056] When the lifting mechanism 2 moves to release the compression of the slider 522, the slide cylinder 524 slides downward relative to the housing 521 according to its own weight, while the stop rod 525 completes the blocking of the housing 521. At this time, the electric telescopic rod 53 pulls the U-shaped locking rod 54 to abut against the stop rod 525, and causes the stop rod 525 to rotate under pressure, so that the U-shaped locking rod 54 enters the housing 521.

[0057] A limiting block is provided in the slide cylinder 524 so that the stop bar 525 can only rotate in one direction. That is, when the U-shaped locking bar 54 enters the housing 521, the stop bar 525 can prevent the U-shaped locking bar 54 from leaving the housing 521, thereby maintaining the protective bar 4 in the unfolded state.

[0058] When the device is stored after the construction work is completed, the lifting mechanism 2 will push the slider 522, which will cause the slide cylinder 524 to slide upward relative to the housing 521 through the action of the guide rope. At the same time, the stop bar 525 will slide upward, so that the stop bar 525 will release the enclosure of the housing 521. After the enclosure is released, the U-shaped locking bar 54 will be released from the housing 521 under the action of the guardrail 4, thereby completing the storage operation of the guardrail 4.

[0059] like Figure 4 As shown, in a preferred embodiment, the lifting base plate 3 includes: a support plate 31, two placement slots 32, a rotating shaft 33, and a guide rail 34;

[0060] The support plate 31 is mounted on the lifting mechanism 2, and a guide rail 34 is fixed at the bottom of the support plate 31. The slider 522 is slidably mounted on the guide rail 34.

[0061] Two placement slots 32 are symmetrically opened on both sides of the support plate 31, and rotating shafts 33 are opened through the support plate 31 at both ends.

[0062] like Figure 5 As shown, the present invention also includes: the guardrail 4 includes: a first support rod 41 and a second support rod 43, which are symmetrically rotatably connected to the rotating shaft 33, wherein the second support rod 43 is also rotatably connected to the linkage rod 51; an adjusting baffle 42, which is rotatably mounted on the first support rod 41 and the second support rod 43 at both ends; and a torsion spring is provided at the connection between the second support rod 43 and the rotating shaft 33.

[0063] like Figure 6 As shown, in a preferred embodiment, the adjusting baffle 42 includes: a first rack 423, one end of which is rotatably mounted on the first support rod 41, and the other end of which is slidably mounted inside the sleeve 421; a second rack 424, one end of which is rotatably mounted on the second support rod 43, and the other end of which is slidably mounted inside the sleeve 421; a gear 422 is rotatably mounted inside the sleeve 421, and the gear 422 meshes with the first rack 423 and the second rack 424.

[0064] When the operation is carried out, when the linkage rod 51 pulls the second support rod 43, the second support rod 43 rotates around the rotating shaft 33. During the rotation of the second support rod 43, the second rack 424 moves. When the second rack 424 moves in the sleeve 421, the gear 424 rotates. The rotation of the gear 424 causes the first rack 423 to slide in the slide cylinder 421 in opposite directions to the second rack 424. The sliding of the second rack 424 and the lifting of the second support rod 43 cause the first support rod 41 to rotate synchronously. That is, when the U-shaped locking rod 54 is locked by the locking assembly 52, the first support rod 41, the second support rod 43 and the adjusting baffle 42 together form a protective structure, thereby providing safety protection.

[0065] It should be noted that during the unfolding process that causes the second support rod 43 to rotate, the torsion spring will simultaneously store force.

[0066] During storage, after the locking assembly 52 releases the U-shaped locking rod 54, the second support rod 43 rotates in the opposite direction under the torque provided by the torsion spring, so that the first support rod 41 rotates synchronously under the action of the adjusting sleeve 42. After the first support rod, the second support rod 43 and the adjusting sleeve 42 are stored, they will be completely placed in the placement groove 32 for protection, preventing damage during transportation and handling.

[0067] After the guardrail 4 is retracted, it is completely inside the placement slot 32; a handle 6 and a moving wheel are also provided on the base 1.

[0068] The above description is merely a specific embodiment of this utility model, but the protection scope of this utility model is not limited thereto. Any variations or substitutions that can be easily conceived by those skilled in the art within the technical scope disclosed in this utility model should be included within the protection scope of this utility model. Therefore, the protection scope of this utility model should be primarily defined by the scope of the claims.
