Description

Technical Field

[0001] This utility model relates to the field of construction equipment technology, specifically to a lifting platform for civil engineering construction with a protective mechanism. Background Technology

[0002] A lifting platform is a type of lifting machinery used for vertically transporting people or goods. It also refers to equipment used for vertical transport in logistics systems such as factories and automated warehouses. Lifting platforms are often equipped with various horizontal conveying devices as connecting devices for conveyor lines at different heights. Workers usually accompany the lifting platform during its lifting and lowering, making its safety protection performance particularly important.

[0003] The existing conventional lifting platform structure does not have an effective protective mechanism on the top of the construction platform. During use, due to the occurrence of objects falling from heights at the construction site, the lack of a protective structure or the use of only ordinary protective plates cannot withstand the impact of falling objects, which undoubtedly increases the working risks for workers on the construction platform.

[0004] Therefore, there is an urgent need for a construction lifting platform with a protective mechanism to solve the problem of poor top protection of conventional lifting platform structures. Utility Model Content

[0005] This utility model addresses the shortcomings of existing technologies by providing a civil construction lifting platform with a protective mechanism to solve the problem of poor top protection in conventional lifting platform structures.

[0006] To achieve the above objectives, the present invention adopts the following technical solution:

[0007] A civil construction lifting platform with a protective mechanism is characterized by comprising a lifting drive mechanism, a lifting platform, and a three-dimensional protective mechanism. The lifting drive mechanism is used to connect and drive the lifting platform to move up and down. The lifting platform is provided with a three-dimensional protective mechanism, which includes fixed walls, rotating plates, irregularly shaped parts, reinforcing plates, and buffer dampers. The lifting platform has two oppositely arranged fixed walls, and a rotating plate is connected to the top opposite surfaces of the two fixed walls. The two rotating plates are used to jointly shield the top of the three-dimensional protective mechanism. The bottom end of each rotating plate is obliquely connected to an irregularly shaped part. The lower end of the irregularly shaped part is also connected to a reinforcing plate. The upper end of the reinforcing plate is connected to the upper end of the irregularly shaped part through a buffer damper. The reinforcing plate is also supported and connected to the corresponding fixed wall.

[0008] To optimize the above technical solution, the specific measures also include:

[0009] Furthermore, it also includes an adjusting support mechanism, wherein two extension blocks located on both sides of the fixed wall are fixedly connected to the top of the inner side wall of each fixed wall, and the two extension blocks on each fixed wall are hinged together with a movable block. The side of the movable block away from the fixed wall is used to connect the rotating plate. The reinforcing plate is supported and connected to the corresponding fixed wall through the adjusting support mechanism. The adjusting support mechanism is used to support and drive the rotating plate to rotate around the hinge point on the corresponding extension block.

[0010] Furthermore, the adjustment support mechanism includes a servo motor, a threaded rod, a lifting block, and a connecting rod. A set of servo motors is respectively provided on the top of the lifting platform and on the inner side of the two fixed walls. The output end of each servo motor is fixedly connected to a vertically arranged threaded rod. The upper end of the threaded rod is rotatably connected to the inner side wall of the corresponding fixed wall. A lifting block is threadedly connected to each threaded rod. The servo motor is used to drive the threaded rod to rotate and drive the lifting block to move up and down along the threaded rod. One end of the connecting rod is hinged to the lifting block, and the other end is hinged to the reinforcing plate.

[0011] Furthermore, each of the rotating plates is fitted with reinforced glass in the middle, and the surface of the reinforced glass is coated with an anti-ultraviolet coating.

[0012] Furthermore, a protective grid is fixedly connected to the rotating plate and above the tempered glass.

[0013] Furthermore, the two rotating plates are a left rotating plate and a right rotating plate, respectively. A pressure block is fixedly connected to the end of the left rotating plate near the right rotating plate, and a pressure groove is provided at the end of the right rotating plate near the left rotating plate for the pressure block to be inserted and engaged.

[0014] Furthermore, each of the fixed walls has a working window in the middle of its side wall.

[0015] Furthermore, protective fences are fixedly connected between the sides of the two fixed walls, and a passageway is reserved in the middle of one side of the protective fence.

[0016] Furthermore, it also includes an electric rotary table, with the top of the lifting platform equipped with an electric rotary table, and the three-dimensional protective mechanism is mounted on the electric rotary table. The electric rotary table is used to drive the three-dimensional protective mechanism to rotate.

[0017] Furthermore, the lifting drive mechanism includes a base, a hydraulic telescopic rod, a sliding block, an adjusting rod, and a sliding seat. The right end of the lifting platform is slidably connected to the vertically arranged sliding seat. The bottom end of the sliding seat is fixedly connected to the base, and the upper end of the base has a sliding groove. The hydraulic telescopic rod is installed inside the sliding groove. The output end of the hydraulic telescopic rod is fixedly connected to the sliding block. The top of the sliding block is hinged to the adjusting rod, and the top end of the adjusting rod is hinged to the bottom of the lifting platform. The hydraulic telescopic rod is used to drive the sliding block to move and drive the lifting platform to move up and down.

[0018] The beneficial effects of this utility model are:

[0019] This utility model, through the combined arrangement of a lifting platform and a three-dimensional protective mechanism, utilizes two rotating plates as a protective structure when top protection is required. The combination of irregularly shaped components, reinforcing plates, and buffer dampers forms a triangular area, enhancing structural stability. Simultaneously, the buffer dampers disperse the force on the rotating plates, increasing the structure's impact resistance. Furthermore, the combination of irregularly shaped components and reinforcing plates increases the rotating plates' compressive strength, effectively protecting workers below and solving the problem of inadequate top protection in conventional lifting platform structures.

[0020] This utility model, through the adjustment and matching of the support mechanism, allows the servo motor to be activated to drive the threaded rod to rotate when top protection is needed. This causes the lifting block to rise, which in turn moves the connecting rod. The connecting rod then drives the reinforcing plate to rotate around the extension block, thereby causing the two rotating plates, namely the left and right rotating plates, to rotate to their working positions in sequence. Simultaneously, the above operation is repeated in reverse to rotate the reinforcing plate and other structures to one side of the working window, preventing them from obstructing the handling of large goods and thus improving the practicality of the structure.

[0021] This invention also includes reinforced glass to provide supplemental lighting and sun protection for workers, as well as a protective grid to protect the reinforced glass. Attached Figure Description

Detailed Implementation

[0028] The present invention will now be described in detail with reference to the accompanying drawings.

[0029] As attached Figure 1 Appendix Figure 2 and attached Figure 5 As shown in the figure, a civil construction lifting platform with a protective mechanism according to an embodiment of the present invention includes a lifting drive mechanism, a lifting platform 1, and a three-dimensional protective mechanism 2. The lifting drive mechanism is used to connect and drive the lifting platform 1 to move up and down. The three-dimensional protective mechanism 2 is provided on the lifting platform 1. The three-dimensional protective mechanism 2 includes a fixed wall 201, a rotating plate, a shaped component 215, a reinforcing plate 208, and a buffer damper 216. The lifting platform 1 has two fixed walls 201 arranged opposite to each other. A rotating plate is connected to the top opposite face of the two fixed walls 201 respectively. The two rotating plates are used to jointly shield the top of the three-dimensional protective mechanism 2. The bottom end of each rotating plate is obliquely connected to the shaped component 215. The lower end of the shaped component 215 is also connected to the reinforcing plate 208. The upper end of the reinforcing plate 208 is connected to the shaped component 215 through the buffer damper 216. The reinforcing plate 208 is also supported and connected to the corresponding fixed wall 201.

[0030] This utility model, through the cooperative arrangement of the lifting platform 1 and the three-dimensional protective mechanism 2, allows for the use of two rotating plates as a protective structure when top protection is required. The combination of the irregularly shaped component 215, the reinforcing plate 208, and the buffer damper 216 forms a triangular area, making the structure more stable. Simultaneously, the buffer damper 216 disperses the force on the rotating plates, increasing the structure's impact resistance. Thus, the cooperation of the irregularly shaped component 215 and the reinforcing plate 208 increases the compressive strength of the rotating plates, enabling effective protection for workers below and solving the problem of poor top protection in conventional lifting platform structures.

[0031] In this design, the aforementioned irregularly shaped component 215 and the reinforcing plate 208 can be connected by two sets of buffer dampers 216 to increase the stability of the structure.

[0032] In a further embodiment based on the above, an adjusting support mechanism is also included. Two extension blocks 213 located on both sides of the inner wall of each fixed wall 201 are fixedly connected to the top of each fixed wall 201. The two extension blocks 213 on each fixed wall 201 are hinged together to a movable block 212. The side of the movable block 212 away from the fixed wall 201 is used to connect a rotating plate. The reinforcing plate 208 is supported and connected to the corresponding fixed wall 201 through the adjusting support mechanism. The adjusting support mechanism is used to support and drive the rotating plate to rotate around the hinge point on the corresponding extension block 213. The extension blocks 213 and the movable blocks 212 prevent the fixed wall 201 from obstructing the rotation of the movable block 212, thereby enabling the rotation of the two rotating plates.

[0033] In this embodiment, the two rotating plates mentioned above are a left rotating plate 205 and a right rotating plate 206. Specifically, the movable blocks 212 on the two fixed walls 201 are respectively fixedly connected to the left rotating plate 205 and the right rotating plate 206. The bottom ends of the left rotating plate 205 and the right rotating plate 206 are connected to irregular parts 215. The bottom end of the irregular parts 215 is connected to a reinforcing plate 208. The top end of the reinforcing plate 208 is equipped with a buffer damper 216, and the top end of the buffer damper 216 is fixedly connected to the top wall of the irregular parts 215.

[0034] As attached Figure 3 As shown, in a further embodiment based on the above, the adjustment support mechanism includes a servo motor 210, a threaded rod 209, a lifting block 211, and a connecting rod 207. A set of servo motors 210 is respectively provided on the top of the lifting platform 1 and on the inner side of the two fixed walls 201. The output end of each servo motor 210 is fixedly connected to a vertically arranged threaded rod 209. The upper end of the threaded rod 209 is rotatably connected to the inner side wall of the corresponding fixed wall 201. The threaded rod 209 is threadedly connected to a lifting block 211. The servo motor 210 is used to drive the threaded rod 209 to rotate and drive the lifting block 211 to move up and down along the threaded rod 209. One end of the connecting rod 207 is hinged to the lifting block 211, and the other end is hinged to the reinforcing plate 208.

[0035] In use, the servo motor 210 can be started to drive the threaded rod 209 to rotate, causing the lifting block 211 to rise and drive the connecting rod 207 to move. Then, the connecting rod 207 drives the reinforcing plate 208 to carry the corresponding rotating plate to rotate around the extension block 213. Specifically, the left rotating plate 205 and the right rotating plate 206 are rotated to the working position in sequence. In use, the above operation can also be repeated in reverse to rotate the reinforcing plate 208 to the side close to the fixed wall 201, which can prevent it from obstructing the handling of large goods, thereby improving the practicality of the structure.

[0036] In another specific embodiment based on the above, a reinforced glass 214 is installed in the middle of each rotating plate, and the surface of the reinforced glass 214 is coated with an anti-ultraviolet coating. Thus, the reinforced glass 214 can be used to provide supplemental lighting and sun protection for workers.

[0037] In a further embodiment based on the above, a protective grid 204 is fixedly connected to the rotating plate above the tempered glass 214. Thus, the tempered glass 214 can be protected by the protective grid 204.

[0038] As attached Figure 4 As shown, in another specific embodiment based on the above, the two rotating plates are a left rotating plate 205 and a right rotating plate 206. A pressure block is fixedly connected to the end of the left rotating plate 205 near the right rotating plate 206, and a pressure groove is provided on the end of the right rotating plate 206 near the left rotating plate 205 for the pressure block to be inserted and engaged. This facilitates the engagement and limiting of the two rotating plates, namely the left rotating plate 205 and the right rotating plate 206, and improves the stability of the structure.

[0039] In another specific embodiment based on the above, a working window 203 is provided in the middle of the side wall of each fixed wall 201. This facilitates observation and work by staff from multiple directions.

[0040] In another specific embodiment based on the above, a protective fence 202 is fixedly connected between the sides of the two fixed walls 201, and a passage groove is reserved in the middle of one side of the protective fence 202.

[0041] In another specific embodiment based on the above, an electric rotary table 3 is also included. The top of the lifting platform 1 is equipped with an electric rotary table 3, and a three-dimensional protective mechanism 2 is installed on the electric rotary table 3. The electric rotary table 3 is used to drive the three-dimensional protective mechanism 2 to rotate. In use, the electric rotary table 3 can be started to rotate, causing the workers on the lifting platform 1 to adjust their working angle and position, and the protective fence 202 described above can be used to protect the workers.

[0042] In this embodiment, the aforementioned structures such as the servo motor 210, the fixed wall 201, and the protective fence 202 can all be installed on the electric rotary table 3.

[0043] In another specific embodiment based on the above, the lifting drive mechanism includes a base 4, a hydraulic telescopic rod 5, a sliding block 6, an adjusting rod 7, and a sliding seat 8. The right end of the lifting platform 1 is slidably connected to the vertically arranged sliding seat 8. The bottom end of the sliding seat 8 is fixedly connected to the base 4. A groove is opened at the upper end of the base 4, and the hydraulic telescopic rod 5 is installed inside the groove. The output end of the hydraulic telescopic rod 5 is fixedly connected to the sliding block 6. The top of the sliding block 6 is hinged to the adjusting rod 7, and the top end of the adjusting rod 7 is hinged to the bottom of the lifting platform 1. The hydraulic telescopic rod 5 is used to drive the sliding block 6 to move and drive the lifting platform 1 to move up and down. In this way, the sliding seat 8 can realize the vertical sliding limit of the lifting platform 1, and the hydraulic telescopic rod 5 can drive the sliding block 6 and the adjusting rod 7 to move, so as to realize the lifting drive of the lifting platform 1.

[0044] One specific embodiment of this utility model is as follows:

[0045] When construction is required on structures such as office buildings, the base 4 is transported to the designated position. The hydraulic telescopic rod 5 is activated, causing the sliding block 6 to slide, which in turn moves the adjusting rod 7 and the lifting platform 1. The lifting platform 1 is then raised and lowered within the sliding seat 8 to the designated position, and the construction angle is adjusted with the assistance of the electric rotary table 3. Subsequently, the servo motor 210 is activated, causing the threaded rod 209 to rotate, which raises the lifting block 211 to move the connecting rod 207. The connecting rod 207 then drives the reinforcing plate 208 to rotate around the extension block 213, thereby causing the left rotating plate 205 and the right rotating plate 206 to rotate to the working position in sequence. The irregular part 215 forms a triangular area to make the structure more stable, and the buffer damper 216 disperses the force on the left rotating plate 205 and the right rotating plate 206, so that they are buffered when subjected to vibration. The protective grid 204 protects the tempered glass 214. The tempered glass 214 can also be used to supplement the lighting and protect the workers from the sun.

[0046] When it is necessary to move goods that are taller than the left rotating plate 205 and the right rotating plate 206, the above operation can be repeated in reverse so that the reinforcing plate 208 and other structures can rotate together to one side of the working window 203 to prevent them from obstructing the handling of large goods, thereby improving the practicality of this utility model.
