Description

Technical Field

[0001] The utility model relates to the field of construction scaffolds, in particular to a construction scaffold for engineering construction. Background Technique

[0002] During the construction process, construction scaffolds are required to facilitate construction. Sometimes, construction workers need to work at different height positions. Working under the conditions of no foothold or no leaning point has a relatively high risk coefficient. Therefore, it is necessary to properly establish a firm foothold before construction can be carried out. At this time, a construction scaffold is needed. The existing construction scaffold used in engineering construction, such as a construction scaffold for engineering construction with the publication number CN219952601U, includes an equipment box body. An elevating platform is arranged above the equipment box body. A positioning card slot is opened inside the elevating platform. A positioning slider is slidably connected inside the positioning card slot. An extending platform is fixedly connected above the positioning slider. A positioning sliding groove is opened on the surface of the elevating platform. A support rod is slidably connected inside the positioning sliding groove. The upper part of the support rod is fixedly connected to the extending platform. Universal wheels are rotatably connected below the equipment box body. A limiting sliding groove is opened above the equipment box body.

[0003] When the above-mentioned construction scaffold is in use, when the construction width is not enough, the extending platforms on both sides are pulled outwards to extend the working platform, achieving the purpose of increasing the width of the working platform. However, there are no guardrails installed at the top of the elevating platform and the extending platform, resulting in a low safety factor. In addition, when using the extending platform, it needs to be manually pulled outwards, consuming the physical strength of workers. Therefore, we propose a construction scaffold for engineering construction. Content of the Utility Model

[0004] The purpose of the utility model is to provide a construction scaffold for engineering construction, including a working platform. Two groups of extension plates are slidably connected in the sliding grooves opened inside the working platform. A group of screw rods I are respectively threadedly connected to the inner sides of the two groups of extension plates. The two groups of screw rods I are respectively fixedly connected to the two driving ends of a double-shaft motor. Two rows of fixing seats I are fixedly installed at the top of the working platform. A plurality of groups of guard rods I are installed through the inner sides of the fixing seats I. Two groups of guard rods II are slidably arranged inside the guard rods I. The ends of the guard rods II far away from the guard rods I are fixedly connected to fixing seats II. There are four groups of fixing seats II. Two groups of fixing seats II are respectively fixedly connected to the outer walls of the two groups of extension plates. A guard door that can be opened and closed is hingedly installed between the two groups of fixing seats II fixedly connected to the same group of extension plates. Two groups of lifting components are fixedly connected to the bottom of the working platform.

[0005] Preferably: The two groups of screw rods I are respectively rotatably connected to a group of stabilizing plates through bearings. The two groups of stabilizing plates are both fixedly installed in the sliding grooves. The double-shaft motor is fixedly installed in the sliding grooves.

[0006] Preferably, two guiding rods I are respectively and slidably connected to the inner sides of the two extension plates. One end of each guiding rod I is fixedly connected to a stabilizing plate, and the other end of each guiding rod I is fixedly connected to the inner wall of the sliding groove.

[0007] Preferably, the lifting assembly includes two lifting rods. The lower ends of the two lifting rods are respectively and slidably connected to the inner cavities of the lifting sleeves. A screw rod II is respectively and threadedly connected to the inner sides of the lifting rods. The screw rod II is rotatably connected to a limiting plate through a bearing, and the limiting plate is fixedly connected to the inner wall of the lifting sleeve. The two lifting sleeves are rotatably connected to a rotating shaft through bearings. One end of each of the two ends of the rotating shaft is fixedly connected to a helical gear I. The two helical gears I are respectively engaged with a helical gear II, and the two helical gears II are respectively fixedly installed at the bottom ends of the two screw rods II.

[0008] Preferably, the tops of the lifting rods are fixedly connected to a workbench, and the lifting sleeves are fixedly installed on the top end of the base.

[0009] Preferably, a universal wheel with a brake pad is installed at each of the four corners of the bottom of the base.

[0010] Preferably, a gear I is fixedly sleeved on the outer walls of the two rotating shafts, and the two gears I are engaged with a chain. A gear II is fixedly sleeved on the outer wall of one of the rotating shafts, and the gear II is engaged with a gear III. The gear III is fixedly connected to the driving end of a motor, and the motor is fixedly installed on the top end of the base.

[0011] Compared with the prior art, the beneficial effects of the present utility model are as follows:

[0012] 1. During the use of the present utility model, when it is found that the width of the workbench is insufficient, starting the double-shaft motor will drive the two screw rods I to rotate simultaneously. The rotation of the two screw rods I will drive the two extension plates to slide outwards along the sliding groove, thereby facilitating the work of workers without the need for manual pulling of the extension plates.

[0013] 2. During the process of the extension plates sliding outwards along the sliding groove, the fixing seat II is driven to move. The movement of the fixing seat II drives the protective rod II to slide outwards along the inner cavity of the protective rod I. Thus, through the protective rod II, the protective rod I and the protective door, the workers can be protected to prevent them from falling when working above the workbench or the extension plates; and when adjusting the lengths of the workbench and the extension plates, the protective rod I and the protective rod I can be adjusted in length accordingly.

[0014] 3. When the present utility model is in use, starting the motor will drive the gear III to rotate. The rotation of the gear III will drive the gear II to rotate. The rotation of the gear II drives the two rotating shafts to rotate simultaneously through the transmission of the gear I and the chain. The rotation of the rotating shaft drives the helical gear I to rotate. The rotation of the helical gear I drives the helical gear II to rotate. The rotation of the helical gear II drives the screw rod II to rotate. The rotation of the screw rod II drives the lifting rod to move up and down along the lifting sleeve, thereby adjusting the height of the workbench. Brief Description of the Drawings
