Technical Field

[0001] This utility model belongs to the field of scaffolding technology, specifically relating to a scaffolding with adjustable height and angle. Background Technology

[0002] Scaffolding is an indispensable and important facility in building construction. It is a working platform erected to ensure the smooth progress of various construction processes, allowing workers to stand on the scaffolding to carry out construction at heights of the building.

[0003] Traditional scaffolding is usually temporary, assembled by using various scaffolding components to form a whole. The height of the assembled scaffolding is generally fixed. When the height of the top platform of the scaffolding needs to be adjusted, the operators need to add more scaffolding components to increase the height of the scaffolding. This operation is relatively troublesome and time-consuming, thus affecting the overall efficiency of the building.

[0004] Therefore, this utility model provides a scaffold with adjustable height and angle to solve the above problems. Utility Model Content

[0005] The purpose of this invention is to provide a scaffold with adjustable height and angle, which aims to solve the problem that the height of assembled scaffolds in the prior art is generally fixed. When the height of the top platform of the scaffold needs to be adjusted, the operator needs to add scaffold accessories to increase the height of the scaffold, which is more troublesome and time-consuming.

[0006] To achieve the above objectives, this utility model provides the following technical solution: an adjustable height and angle scaffold, comprising a base, with columns connected to the top surface at the four corners of the base, a through groove on the front surface of the column, bearings connected to the inner two ends of the groove, a screw connecting the two bearings, one end of the screw extending into the column and connected to the output end of a motor, and a slider threadedly connected to one end of the screw, connecting columns connected to the top surfaces of the slider extending out of the groove, a platform frame connected to the top surface of the connecting columns, a placement groove on the top surface of the platform frame, and a platform plate connected to the inner surface of the placement groove.

[0007] In order to drive the screw to rotate, as a preferred embodiment of the adjustable height and angle scaffolding of this utility model, the motor is located on the top surface of the slot opened at the front end of the bottom of the column, and the output end of the motor is fixedly connected to the screw.

[0008] In order to protect the operators on the platform, as a preferred embodiment of the adjustable height and angle scaffolding of this utility model, the top surface of the four corners of the platform frame is connected to the bottom surface of the guardrail.

[0009] To facilitate the movement and fixation of the scaffolding, as a preferred embodiment of this utility model of an adjustable scaffolding with adjustable height and angle, the bottom surface of the base is connected to four corners.

[0010] To achieve the desired change in the tilt angle of the platform board, as a preferred embodiment of this utility model of an adjustable height and angle scaffold, a rotating shaft is connected to the inner surface of the left side of the placement slot. One end of the rotating shaft is rotatably connected to a rotating block. A platform board is connected to the right side surface of the rotating block. A hinge seat is connected to the bottom surface of the platform board at the end away from the rotating block. One end of the hinge seat passes through a movable slot opened on the bottom surface of the placement slot. A mounting frame is connected to the bottom surface of the platform frame outside the movable slot. An electric push rod is connected to the bottom surface of the mounting frame.

[0011] In order to realize the driving hinge seat, as a preferred embodiment of the height and angle adjustable scaffold of this utility model, the movable end of the electric push rod passes through the mounting frame and is connected to the bottom surface of the movable end of the hinge seat.

[0012] Compared with the prior art, the beneficial effects of this utility model are:

[0013] This invention allows the motor to be started by a switch, which in turn drives the screw to rotate. This causes the slider on the screw to move the connecting column, thus changing the height of the platform frame. This adjusts the position and height of the platform plate on the platform frame, making it easier for operators to carry out construction at other heights, thereby bringing convenience to building construction.

[0014] This invention utilizes the cooperation of a rotating shaft, a rotating block, a hinge seat, and an electric push rod. By activating the electric push rod, the movable end of the electric push rod drives the rotating block on the platform plate to rotate on the rotating shaft through the hinge seat, thereby changing the tilt angle of the platform plate. In this way, when the scaffolding is placed on a slightly tilted site, the platform plate, which follows the tilt of the scaffolding, can be adjusted to a horizontal state, ensuring that the operators on the platform plate can stand stably.

[0021] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0022] Please see Figures 1-4 The present invention provides the following technical solution: a scaffold with adjustable height and angle, including a base 1, with columns 2 connected to the top surface of the four corners of the base 1, a through groove 3 opened on the front surface of the column 2, bearings 4 connected to the inner two ends of the groove 3, a screw 5 connected between the two bearings 4, one end of the screw 5 extending into the column 2 and connected to the output end of the motor 6, and a slider 7 threadedly connected to one end of the screw 5, a connecting column 8 connected to the top surface of the slider 7 extending out of the two ends of the groove 3, a platform frame 9 connected to the top surface of the connecting column 8, a placement groove 10 opened on the top surface of the platform frame 9, and a platform plate 11 connected to the inner surface of the placement groove 10.

[0023] Preferably, the motor 6 is located on the top surface of the slot opened at the front end of the bottom end of the column 2, and the output end of the motor 6 is fixedly connected to the screw 5.

[0024] In practical use, motor 6 can be electrically connected to an external power source via a control switch. By starting motor 6 with the switch, the output end of motor 6 can drive screw 5 to rotate. Screw 5 can be selected with high strength and high load-bearing capacity as needed.

[0025] Preferably, the top surfaces at all four corners of the platform frame 9 are connected to the bottom surface of the guardrail 12.

[0026] In practical use, the guardrail 12 set at the top of the platform frame 9 can protect the operators on the platform plate 11.

[0027] Preferably, the bottom surface of the base 1 at each of the four corners is connected to a self-locking roller 13.

[0028] In practical use, the self-locking rollers 13 at the bottom of the base 1 can easily move the scaffolding. By locking the brakes on the self-locking rollers 13, the position of the scaffolding can be fixed.

[0029] Preferably: a rotating shaft 14 is connected to the inner surface of the left side of the placement slot 10, and a rotating block 15 is rotatably connected to one end of the rotating shaft 14. A platform plate 11 is connected to the right side surface of the rotating block 15. A hinge seat 16 is connected to the bottom surface of the platform plate 11 at the end away from the rotating block 15. One end of the hinge seat 16 passes through the movable slot 17 opened on the bottom surface of the placement slot 10. A mounting bracket 19 is connected to the bottom surface of the platform frame 9 outside the movable slot 17. An electric push rod 18 is connected to the bottom surface of the mounting bracket 19.

[0030] In practical use, the electric push rod 18 is activated, and the movable end of the electric push rod 18 pushes the hinge seat 16 upward. In this way, the hinge seat 16 will drive the rotating block 15 on the platform plate 11 to rotate on the rotating shaft 14, so that the tilt angle of the platform plate 11 on the platform frame 9 will change. After the angle is adjusted, the horizontal state of the platform plate 11 can be adjusted. The size of the movable groove 17 can meet the movable range of the hinge seat 16, ensuring that the hinge seat 16 can be used normally.

[0031] Preferably, the movable end of the electric push rod 18 passes through the mounting bracket 19 and is connected to the bottom surface of the movable end of the hinge seat 16.

[0032] In practical use, the electric push rod 18 is also electrically connected to an external power source via a control switch. By activating the electric push rod 18 through the switch, the movable end of the electric push rod 18 can push the hinge seat 16 to move.

[0033] Working principle: When using this height- and angle-adjustable scaffolding, the self-locking rollers 13 at the bottom of the base 1 can move the scaffolding to the designated construction location. Locking the self-locking rollers 13 then fixes the scaffolding's position. The operator can then use tools to move to the platform 11 and stand, allowing for the adjustment of the construction height. When the operator needs to work at other heights, the motor 6 can be started by switching on it. The output of the motor 6 drives the screw 5 to rotate in the bearing 4, causing the slider 7 on the screw 5 to move along the groove 3. This movement of the slider 7, in turn, moves the platform frame 9 via the connecting column 8, thus changing the height of the platform 11 on the platform frame 9. By adjusting the height of the platform plate 11, operators on the platform plate 11 can perform construction at other heights, thus facilitating construction. Secondly, when the scaffolding is placed on a slightly inclined site, the platform plate 11 at the top of the scaffolding will also be slightly inclined. At this time, by activating the electric push rod 18, the movable end of the electric push rod 18 pushes the hinge seat 16 upward. This causes the hinge seat 16 to drive the rotating block 15 on the platform plate 11 to rotate on the rotating shaft 14, causing the tilt angle of the platform plate 11 on the platform frame 9 to change. After the angle is adjusted, the platform plate 11 can be placed in a horizontal state, allowing operators to stand stably on the platform plate 11.

[0034] Finally, it should be noted that the above description is merely a preferred embodiment of this utility model and is not intended to limit the utility model. Although the utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of this utility model should be included within the protection scope of this utility model.
