Description

Technical Field

[0001] This utility model relates to the field of safety lifting equipment technology, and in particular to a safety lifting device for municipal construction. Background Technology

[0002] In the field of municipal construction, from road and bridge construction to the installation of urban lighting facilities, many operational stages require workers to operate at different heights. Safety lifting devices, as key equipment to ensure smooth construction progress and personnel safety, directly impact the effectiveness of the construction project.

[0003] Traditional lifting devices often employ simple mechanical structures, which are prone to malfunction due to wear and tear and aging of components during long-term, high-intensity use. For example, the drive chain may break, or the hydraulic system may leak. If these situations occur, the lifting platform is highly likely to fall unexpectedly. An unexpected fall not only seriously threatens the lives of construction workers but also forces the construction process to stop, causing delays and increasing additional manpower and material costs. Therefore, we have proposed a safety lifting device for municipal construction to solve the above problems. Utility Model Content

[0004] The purpose of this utility model is to provide a safety lifting device for municipal construction, which effectively protects the safety of construction personnel and prevents the lifting platform from falling accidentally through a reliable anti-fall mechanism and a stable drive system, thereby improving the safety performance of the lifting platform.

[0005] The above-mentioned technical objective of this utility model is achieved through the following technical solution: a safety lifting device for municipal construction, comprising a base, four guide rods mounted on the top of the base in a rectangular shape, a fixed plate fixedly mounted on the top of two corresponding guide rods, a drive plate slidably mounted on the two corresponding guide rods, a lifting platform fixedly mounted between the two drive plates, a guardrail mounted on the top of the lifting platform, an anti-fall mechanism provided between the lifting platform and the fixed plate, a threaded rod rotatably mounted on the bottom of the fixed plate, and the drive plate threadedly sleeved on the threaded rod, the anti-fall mechanism comprising a movable plate, an anti-fall plate and a reinforcing rib, two movable plates slidably mounted on the top of the lifting platform, an anti-fall plate adapted to the fixed plate fixedly mounted on the side of the movable plates that are far apart from each other, a reinforcing rib fixedly mounted on the top of the anti-fall plate, and the top of the reinforcing rib fixedly mounted on the corresponding movable plate.

[0006] By adopting the above technical solutions, through reliable anti-fall mechanisms and stable drive systems, the safety of construction personnel can be effectively guaranteed, and the accidental fall of the lifting platform can be avoided, thereby improving the safety performance of the lifting platform.

[0007] A further feature of this invention is that two rectangular seats are fixedly installed on the top of the lifting platform, and the two rectangular seats are located between two movable plates. The rectangular seats are provided with a pushing mechanism for moving the movable plates. The pushing mechanism includes a threaded hole, a drive screw, and a handle. The threaded hole is opened on the rectangular seat, and the drive screw is threadedly installed inside the threaded hole. One end of the drive screw is rotatably installed on the movable plate, and the other end of the drive screw is fixedly installed with a handle.

[0008] By adopting the above technical solution, construction workers can easily control the movement of the moving plate precisely by turning the handle and using the threaded transmission, thereby flexibly adjusting the position of the fall arrestor. The operation is simple and efficient, greatly improving the convenience of activating the fall arrestor function.

[0009] A further feature of this invention is that a rotating groove is provided on one side of the movable plate, an annular groove is provided on the inner wall of the rotating groove, an annular seat is fixedly installed on the drive screw, and the annular seat is rotatably connected to the annular groove.

[0010] By adopting the above technical solution, the connection structure is more stable and smooth during the rotation of the drive screw and the translation of the moving plate, avoiding jamming or damage between the drive screw and the moving plate due to relative movement, and effectively extending the service life of the push mechanism.

[0011] A further feature of this invention is that the top of the lifting platform is provided with a movable groove, and the movable plate is slidably connected to the corresponding movable groove. The same limiting rod is fixedly installed on the inner walls of both sides of the movable groove. A limiting hole is provided on the movable plate, and the limiting hole is slidably sleeved on the corresponding limiting rod.

[0012] By adopting the above technical solution, the moving plate can always maintain a straight trajectory during the movement process without deviation or shaking, ensuring the accuracy of the fall arrestor's movement and further improving the stability and reliability of the fall arrestor mechanism.

[0013] A further feature of this invention is that: two support seats are fixedly installed on the top of the base, and the same stabilizing plate is fixedly installed on the top of the two support seats; a driving mechanism connected to a threaded rod is provided at the bottom of the stabilizing plate; a dual-axis motor is fixedly installed at the bottom of the stabilizing plate; a driving bevel gear is fixedly installed on each of the two output shafts of the dual-axis motor; a driven bevel gear is fixedly installed at the bottom end of the threaded rod; and the driving bevel gear meshes with the corresponding driven bevel gear.

[0014] By adopting the above technical solution, the dual-axis motor can drive two threaded rods to rotate synchronously, providing a stable and balanced driving force for the lifting platform, ensuring smooth lifting and effectively preventing tilting or jamming of the platform during the lifting process.

[0015] A further feature of this invention is that: a rotating hole is provided on the stabilizing plate, and the threaded rod is rotatably connected to the corresponding rotating hole; multiple rollers are installed at the bottom of the base, and the rollers are lockable casters.

[0016] By adopting the above technical solution, the threaded rod rotates smoothly in the rotating hole, reducing rotational friction resistance. Combined with the lockable casters, the device can be flexibly turned when moved to the construction site, and can be quickly locked after reaching the designated position, enhancing the adaptability and ease of operation of the device in different construction sites.

[0017] The beneficial effects of this utility model are:

[0018] (1) After the base is moved to the designated position, when the construction personnel stand on the lifting platform, the dual-axis motor is started. The dual-axis motor can drive the drive bevel gear to rotate through the output shaft. The drive bevel gear can drive the threaded rod to rotate through the driven bevel gear. The threaded rod can drive the drive plate and the lifting platform to move upward, thereby achieving the purpose of lifting the construction personnel.

[0019] (2) When the lifting platform moves to the highest point, the personnel standing on the lifting platform can turn the handle and drive screw. Under the action of the screw, the drive screw can rotate and move at the same time. The drive screw can move the moving plate, and the moving plate can move the anti-fall plate above the fixed plate. The two anti-fall plates can prevent the lifting platform from falling accidentally, which can improve the safety performance of the lifting platform. Attached Figure Description
