Abstract
Description
Technical Field
[0001] This utility model relates to the field of construction ladder technology, specifically a construction ladder for building engineering with a protective structure. Background Technology
[0002] Construction projects refer to engineering entities formed through the construction of various buildings and their ancillary facilities, as well as the installation of supporting lines, pipelines, and equipment. These include factories, theaters, hotels, shops, schools, hospitals, and residences, which meet people's needs for production, living, learning, and public activities. During construction, construction ladders are needed to assist in work at higher locations.
[0003] As disclosed in announcement number CN 217652283 U, a construction ladder with a protective structure includes a base plate and a ladder. Handbrake wheels are installed at the bottom of the base plate near the four corners. The base plate is a hollow U-shaped plate structure. A fixing plate is rotatably installed on the front end face of the base plate through a pin. The left and right side walls of the fixing plate have round holes. This device does not have an adjustable auxiliary support mechanism and cannot be strengthened by engaging the fixing screws inside the auxiliary support rod with the first threaded hole. The stability of the construction ladder cannot be guaranteed, and personnel may fall due to insecure fixing. In addition, the construction ladder does not have a foldable mechanism for its retraction and storage. Conventional construction ladders occupy a large space, which is not conducive to the later bulk transportation. Utility Model Content
[0004] The purpose of this utility model is to provide a construction ladder for building engineering with a protective structure to solve the problems mentioned in the background art.
[0005] To achieve the above objectives, this utility model provides the following technical solution:
[0006] A construction ladder for building engineering with a protective structure includes a load-bearing plate. Protective support mechanisms are movably arranged on both sides of the load-bearing plate. Each protective support mechanism includes a groove, a movable support rod, a first threaded hole, an auxiliary support rod, a second threaded hole, and a fixing screw. Grooves are formed on both sides of the load-bearing plate, and several movable support rods are movably arranged on both sides of the grooves. Two first threaded holes are formed at the center of each groove. An auxiliary support rod is movably arranged on one side of each movable support rod. A second threaded hole is formed on the side of the auxiliary support rod away from the movable support rod. A fixing screw is movably arranged inside the second threaded hole, and one side of the fixing screw is movably connected to the first threaded hole.
[0007] Preferably, handrails are fixedly provided on both sides of the top of the support plate, which facilitates climbing by the user.
[0008] Preferably, the movable support rod is fixedly provided with several climbing poles on its side, which allow users to easily climb onto the support plate to perform operations.
[0009] Preferably, a base block is movably provided at the bottom end of the movable support rod, and connecting rods are provided on both sides of the bottom end of the movable support rod. The connecting rods are movably connected to the inner wall of the base block, and a connecting block is fixedly provided on the side of the base block. The base block and the connecting rod are movably connected to provide load-bearing support, and the connecting block can provide stable support.
[0010] Preferably, a base plate is fixedly provided at the bottom end of the base block, and several casters are fixedly provided on both sides of the bottom end of the base plate. Foot brakes are movably provided on the sides of the casters. The casters allow the device to be easily moved in all directions, saving time and effort. Users can use the foot brakes to control the movement speed of the casters.
[0011] Preferably, the base plate has threaded grooves on both sides inside, and a threaded post is movably arranged inside the threaded groove. A rotating handle is fixedly arranged at the top of the threaded post, and a pad is fixedly arranged at the bottom of the threaded post. Rotating the rotating handle allows the threaded post to move up and down inside the threaded groove. The pad provides stable support. This switchable fixing method greatly improves the applicability of the device.
[0012] Compared with the prior art, the beneficial effects of this utility model are:
[0013] 1. A construction ladder for building engineering with a protective structure. The device first uses casters to move the construction ladder to a designated location. Once at the designated location, workers can rotate the handle to move the threaded column up and down along the threaded groove. Then, a pad is used for stable support. The position of the movable support rod is manually adjusted so that its top and bottom ends are perpendicularly connected to the bearing plate and base block, respectively. After fixing the position, the position of the auxiliary support rod on the outside of the movable support rod is adjusted so that the second threaded hole on one side is aligned with the first threaded hole. Then, the fixing screw is rotated through its interior to fix the position of the movable support rod. Finally, workers can use the climbing pole to climb onto the bearing plate to work.
[0014] 2. A construction ladder for building engineering with a protective structure. The device has an adjustable auxiliary support mechanism. The ladder is reinforced by the engagement of the fixing screw inside the auxiliary support rod with the first threaded hole, which ensures the stability of the construction ladder to a certain extent and prevents personnel from falling due to the ladder being not securely fixed. In addition, the foldable construction ladder can be retracted and stored when not in use, reducing the space it occupies and facilitating bulk transportation in the future.
