Description

Technical Field

[0001] This invention relates to the field of building construction technology, and in particular to a building construction platform frame for uneven ground. Background Technology

[0002] Construction is a production activity carried out by people using various building materials and machinery according to specific design blueprints within a certain space and time to build various types of building products. Among these activities, construction platforms play a crucial role, enabling workers to safely perform work at heights. However, the ground at construction sites is often uneven, which can easily lead to instability when placing the platform. For example, some legs may not make uniform contact with the ground, causing the platform to sway or tilt. This not only increases the difficulty of construction but may also endanger worker safety.

[0003] The existing technology suffers from the following problems: In practical applications, existing construction platform frames face stability threats due to uneven ground surfaces. This unevenness often results in insufficient contact between the platform frame's support mechanism and the ground, reducing the contact area and thus affecting the overall structural stability. This lack of stability not only increases the risks during construction but is particularly evident during platform frame height adjustments. Due to the lack of an effective height restriction mechanism, the lifting mechanism may experience partial structural instability during height adjustments, increasing the risk of the platform frame accidentally falling and posing a serious threat to the safety of workers. Summary of the Invention

[0004] The technical problem to be solved by the present invention is to provide a construction platform frame for uneven ground, which solves the problem of insufficient stability of existing construction platforms on uneven ground, as well as the safety risks of the lifting mechanism when adjusting the height.

[0005] The technical solution adopted by this invention to solve its technical problem is as follows: A construction platform frame for uneven ground is provided, comprising a support mechanism, a moving mechanism, and a lifting mechanism. A support mechanism is installed at each of the four corners of the bottom of the moving mechanism, and a lifting mechanism is installed at the top of the moving mechanism. A construction platform is fixedly installed on the top of the lifting mechanism. The support mechanism includes a drive motor, a bevel gear, a guide frame, and legs. The drive motor is vertically installed at the center of the bottom of the moving mechanism. Four guide frames are fixedly installed around the drive motor at the bottom of the moving mechanism. A threaded extension support plate is slidably installed inside each guide frame. A bevel gear is installed on the output end of the drive motor. Four bevel gear screws are circumferentially meshed around the outer side of the bevel gear. One end of each bevel gear screw is threadedly connected to the threaded extension support plate. An adjusting screw is threadedly connected to the end of the threaded extension support plate away from the drive motor. The adjusting screw is vertically arranged, and a ball head is installed at the lower end of the adjusting screw. A spherical groove that mates with the ball head is opened in the middle of the upper end of the legs.

[0006] As a supplement to the technical solution described in this invention, the cross-section of the threaded sleeve extension support plate is rectangular, and the guide frame is a rectangular frame structure that cooperates with the threaded sleeve extension support plate.

[0007] As a supplement to the technical solution described in this invention, the support leg includes a triangular bracket, a ball joint, and a support plate. A ball joint is vertically installed at each of the three corners at the lower end of the triangular bracket, and the ball head at the lower end of the ball joint is movably sleeved with the support plate.

[0008] As a supplement to the technical solution described in this invention, the lifting mechanism includes side guide plates, lifting support frames, and a second drive motor. A side guide plate is installed on both the front and rear sides of the upper end of the moving mechanism and on both the front and rear sides of the lower end of the construction platform. A scissor-type support assembly is installed between every two adjacent side guide plates. Each scissor-type support assembly consists of two vertically connected lifting support frames. The lifting support frame has an X-shaped structure and consists of cross-arranged fixed arms and movable arms. The middle part of the fixed arm is hinged to the middle part of the movable arm. The fixed arms at both ends of the scissor-type support assembly are rotatably connected to the corresponding side guide plates. The movable arms at both ends of the scissor-type support assembly are laterally slidably connected to the corresponding side guide plates. Two horizontal plates are installed side-by-side between the middle parts of the two scissor-type support assemblies. A control device is installed between the two horizontal plates to control the relative movement of the two horizontal plates.

[0009] As a supplement to the technical solution described in this invention, the control device includes a second drive motor, a transmission screw, and a screw sleeve. The second drive motor is fixedly installed in the middle of the left horizontal plate. The output end of the second drive motor passes through the left horizontal plate and is connected to the transmission screw. A screw sleeve is threaded onto the transmission screw and is fixed in the middle of the right horizontal plate.

[0010] As a supplement to the technical solution described in this invention, each side guide plate is provided with a horizontal track groove, and the movable arms at both ends of the scissor bracket assembly are provided with pulleys that slide back and forth along the corresponding track grooves.

[0011] As a supplement to the technical solution described in this invention, both upper side guide plates are provided with guide grooves, which are located directly below the track groove. A slider is slidably connected in the guide groove, and an arc-shaped limiting block is installed at the upper end of the slider. The arc-shaped limiting block overlaps with the right side of the pulley. A bevel gear screw is internally threaded to the lower part of the slider. The bevel gear screw is horizontally arranged. An adjusting bevel gear rod is rotatably connected to the right side of the two upper side guide plates. The adjusting bevel gear rod is vertically arranged, and the bevel gear at the bottom of the adjusting bevel gear rod meshes with the bevel gear on the right side of the bevel gear screw.

[0012] Beneficial effects: This invention relates to a construction platform frame for uneven ground, which has the following advantages:

[0013] 1.

[0023] The present invention will be further illustrated below with reference to specific embodiments. It should be understood that these embodiments are for illustrative purposes only and are not intended to limit the scope of the invention. Furthermore, it should be understood that after reading the teachings of this invention, those skilled in the art can make various alterations or modifications to the invention, and these equivalent forms also fall within the scope defined by the appended claims.

[0024] Embodiments of the present invention relate to a construction platform frame for uneven ground, such as... Figure 1-6 As shown, the system includes a supporting mechanism 1, a moving mechanism 2, and a lifting mechanism 3. A supporting mechanism 1 is installed at each of the four corners of the bottom of the moving mechanism 2. A lifting mechanism 3 is installed at the top of the moving mechanism 2, and a construction platform 4 is fixedly installed on the top of the lifting mechanism 3. Figure 2 As shown, the supporting mechanism 1 includes a drive motor 11, a bevel gear 12, a guide frame 14, and a support leg. The drive motor 11 is vertically mounted at the center of the bottom of the moving mechanism 2. Four guide frames 14 are fixedly mounted around the drive motor 11 at the bottom of the moving mechanism 2. A threaded sleeve extension support plate 15 is slidably mounted inside each guide frame 14. A bevel gear 12 is mounted on the output end of the drive motor 11. Four bevel gear screws 13 are circumferentially meshed around the outer side of the bevel gear 12. One end of each bevel gear screw 13 is threadedly connected to the threaded sleeve extension support plate 15. An adjusting screw 16 is threadedly connected to the end of the threaded sleeve extension support plate 15 away from the drive motor 11. The adjusting screw 16 is vertically arranged, and a ball head 17 is mounted at the lower end of the adjusting screw 16. Figure 3 As shown, a spherical groove is provided in the middle of the upper end of the support leg to cooperate with the ball head 17, and the outer wall of the ball head 17 is movably connected with the inner wall of the spherical groove.

[0025] The drive motor 11 drives the bevel gear 12 to rotate, so that the bevel gear 12 drives the four bevel gear screws 13 to rotate simultaneously, causing the four screw sleeve extension support plates 15 to extend or retract, thereby achieving the purpose of controlling the screw sleeve extension support plates 15.

[0026] like Figure 2 As shown, a guide frame 14 is movably sleeved on the outer wall of the threaded sleeve extension support plate 15. The upper surface of the guide frame 14 is fixedly installed on the bottom of the moving mechanism 2. The cross-section of the threaded sleeve extension support plate 15 is rectangular, and the guide frame 14 is a rectangular frame structure that cooperates with the threaded sleeve extension support plate 15. Through the cooperation between the inner wall of the guide frame 14 and the outer wall of the threaded sleeve extension support plate 15, the two can slide relative to each other, thereby improving the stability of the movement of the threaded sleeve extension support plate 15.

[0027] like Figure 3 As shown, the support includes a triangular bracket 18, a ball joint rod 19, and a support plate 110. A ball joint rod 19 is vertically installed at each of the three corners at the lower end of the triangular bracket 18. The ball joint rod 19 is movably connected to the support plate 110 at its lower end. The movable connection between the ball joint rod 19 and the support plate 110 allows for better contact between the bottom of the three support plates 110 at the bottom of the triangular bracket 18 and the ground, avoiding the problem of the bottom being suspended.

[0028] like Figure 4 , Figure 5 and Figure 6 As shown, the lifting mechanism 3 includes a side guide plate 31, a lifting support frame 32, and a drive motor 34. A side guide plate 31 is installed on both the front and rear sides of the upper end of the moving mechanism 2 and on both the front and rear sides of the lower end of the construction platform 4. A scissor-type support assembly is installed between every two adjacent side guide plates 31. Each scissor-type support assembly consists of two vertically connected lifting support frames 32. The lifting support frame 32 has an X-shaped structure and is composed of a fixed arm 321 and a movable arm 322 arranged in a cross configuration. The middle part of the fixed arm 321 is hinged to the middle part of the movable arm 322. The fixed arms 321 at both ends of the scissor-type support assembly are rotatably connected to the corresponding side guide plate 31. The movable arms 322 at both ends of the scissor-type support assembly are laterally slidably connected to the corresponding side guide plate 31. Two horizontal plates 33 are installed side-by-side between the middle parts of the two scissor-type support assemblies. A control device is installed between the two horizontal plates 33 to control the relative movement of the two horizontal plates 33.

[0029] The control device includes a second drive motor 34, a transmission screw 35, and a screw sleeve 36. The second drive motor 34 is fixedly installed in the middle of the left horizontal plate 33. The output end of the second drive motor 34 passes through the left horizontal plate 33 and is connected to the transmission screw 35. The transmission screw 35 is threadedly connected to the screw sleeve 36, which is fixed in the middle of the right horizontal plate 33.

[0030] Driven by the second drive motor 34, the transmission screw 35 rotates, and the threaded connection between the transmission screw 35 and the screw sleeve 36 controls the distance between the two horizontal plates 33, thereby controlling the scissor bracket assembly and adjusting the height of the construction platform 4 for better height control. When the distance between the two horizontal plates 33 increases, the height of the construction platform 4 decreases; when the distance between the two horizontal plates 33 decreases, the height of the construction platform 4 increases.

[0031] like Figure 5 As shown, each side guide plate 31 has a horizontally formed track groove 38. The movable arms 322 at both ends of the scissor bracket assembly are equipped with pulleys 37 that slide back and forth along the corresponding track groove 38. The inner wall of the track groove 38 is slidably connected to the outer wall of the pulley 37. The sliding connection between the pulley 37 and the track groove 38 allows for better control of the lifting support frame 32.

[0032] Both upper side guide plates 31 are provided with guide grooves 312, which are located directly below the track groove 38. A slider 311 is slidably connected in the guide groove 312. An arc-shaped limiting block 310 is installed on the upper end of the slider 311. The arc-shaped limiting block 310 overlaps with the right side of the pulley 37. A bevel gear screw 313 is internally threaded to the lower part of the slider 311. The bevel gear screw 313 is arranged horizontally. The right side of the two upper side guide plates 31 is rotatably connected to an adjusting bevel gear rod 39. The adjusting bevel gear rod 39 is arranged vertically. The bevel gear at the bottom of the adjusting bevel gear rod 39 meshes with the bevel gear on the right side of the bevel gear screw 313. By controlling the position of the arc-shaped limiting block 310, the position of the pulley 37 can be limited. The position of the pulley 37 can be controlled at the top of the construction platform 4 to prevent the construction platform 4 from suddenly falling.

[0033] The present invention uses the supporting mechanism 1 to facilitate the support of the four corners of the bottom of the construction platform frame, thereby improving the stability of the bottom of the construction platform frame. At the same time, the components at the top of the lifting mechanism 3 are used to limit one side of the top of the lifting support frame 32, thereby preventing the construction platform 4 from suddenly falling.

[0034] Working Principle: First, the construction platform frame is moved to a suitable position. Driven by the drive motor 11, the bevel gear 12 rotates, causing the four bevel gear screws 13 to rotate. This, in turn, drives the four threaded extension support plates 15 through a threaded connection. Guided by the guide frame 14, the threaded extension support plates 15 are pushed out of the inner cavity of the guide frame 14, pushing the adjusting screw 16 to a suitable position. Then, rotating the adjusting screw 16 pushes the ball head 17 downwards through the threaded connection, moving the triangular bracket 18 to a suitable position. This allows the bottom of the support plate 110 to connect with the uneven ground. Simultaneously, the movable connection between the ball head rod 19 and the support plate 110 improves the contact area between the bottom of the support mechanism 1 and the ground, thereby enhancing the construction efficiency. The stability of the platform frame bottom is ensured, and then the drive motor 34 drives the transmission screw 35 to rotate. The transmission screw 35 and the screw sleeve 36, through the threaded connection, control the distance between the two horizontal plates 33, thereby controlling the height of the construction platform 4. When the height of the construction platform 4 is moved to the appropriate position, the worker can stand on the construction platform 4 and rotate the two front and rear adjusting bevel gear rods 39. The meshing action between the adjusting bevel gear rods 39 and the bevel gear screw 313 drives the bevel gear screw 313 to rotate. The threaded connection between the bevel gear screw 313 and the slider 311 controls the position of the slider 311. This allows the arc-shaped limit block 310 to block the right side of the outer wall of the pulley 37, thereby limiting the pulley 37 and preventing the construction platform frame from suddenly falling during operation.

[0035] In the description of this invention, it should be understood that the orientation or positional relationship indicated by directional terms such as "front, back, up, down, left, right", "horizontal, vertical, horizontal" and "top, bottom" is generally based on the orientation or positional relationship shown in the accompanying drawings, and is only for the convenience of describing this invention and simplifying the description. Unless otherwise stated, these directional terms do not indicate or imply that the device or element referred to must have a specific orientation or be constructed and operated in a specific orientation, and therefore should not be construed as a limitation on the scope of protection of this invention; the directional terms "inner" and "outer" refer to the inner and outer contours relative to the outline of each component itself.

[0036] For ease of description, spatial relative terms such as "above," "on top of," "on the upper surface of," "above," etc., are used herein to describe the spatial positional relationship of a device or feature as shown in the figures to other devices or features. It should be understood that spatial relative terms are intended to encompass different orientations in use or operation beyond the orientation of the device as described in the figures. For example, if the device in the figures were inverted, a device described as "above" or "on top of" other devices or structures would subsequently be positioned as "below" or "under" other devices or structures. Thus, the exemplary term "above" can include both "above" and "below." The device may also be positioned in other different ways (rotated 90 degrees or in other orientations), and the spatial relative descriptions used herein will be interpreted accordingly.

[0037] Furthermore, it should be noted that the use of terms such as "first" and "second" to define components is merely for the purpose of distinguishing the corresponding components. Unless otherwise stated, the above terms have no special meaning and therefore should not be construed as limiting the scope of protection of this invention.

[0038] The above provides a detailed description of a construction platform frame for uneven ground provided in this application. Specific examples have been used to illustrate the principles and implementation methods of this application. The description of the above embodiments is only for the purpose of helping to understand the method and core ideas of this application. At the same time, for those skilled in the art, there will be changes in the specific implementation methods and application scope based on the ideas of this application. Therefore, the content of this specification should not be construed as a limitation of this application.
