Abstract
Description
Technical Field
[0001] This utility model relates to the field of construction scaffolding technology, and in particular to a construction scaffolding. Background Technology
[0002] Scaffolding is a working platform erected to ensure the smooth progress of various construction processes. During construction, scaffolding provides convenient working conditions for construction workers. For scaffolding that requires height adjustment, an elevated working platform needs to be installed on the scaffolding. There are strict limits on the load-bearing capacity of the elevated working platform. Overloading is strictly prohibited and should ideally be within the safety factor. Otherwise, if the working platform falls after being raised, it will threaten the lives of workers and cause property damage. However, existing scaffolding usually does not have overload warnings. For example, when applying paint to walls, construction workers with low safety awareness often load more materials in order to save time, leading to overloading and safety hazards. Utility Model Content
[0003] In view of the above-mentioned prior art, the present invention provides a construction scaffold, which mainly solves the above-mentioned technical problems.
[0004] To achieve the above objectives, the technical solution of this utility model embodiment is implemented as follows:
[0005] A construction scaffold includes an electric lifting assembly. The electric lifting assembly has a lifting plate, and the lifting plate has a plurality of first springs. One end of each first spring is connected to the lifting plate, and the other end of each first spring is connected to a pedal. The pedal is slidably connected to the lifting plate. The lifting plate has a proximity sensor disposed between the lifting plate and the pedal. The lifting plate has a guardrail and a safety door. The safety door is hinged to the guardrail, and the guardrail has an alarm light.
[0006] Furthermore, the electric lifting assembly includes a lower base plate, lifting connecting rods, and an upper base plate. The lifting plate is mounted on the upper base plate. Two sets of lifting connecting rods are provided, each set consisting of several hinged links. The lower front ends of both sets of lifting connecting rods are hinged to the upper part of the lower base plate, and the lower rear ends of both sets of lifting connecting rods are slidably connected to the upper part of the lower base plate. The two sets of lifting connecting rods together form a scissor mechanism. The lower front end of the upper base plate is hinged to the upper part of the lifting connecting rods, and the lower rear end of the upper base plate is slidably connected to the lifting connecting rods. The lifting connecting rods are equipped with a rotating shaft. The lower base plate is equipped with a motor with a brake. The output end of the motor with the brake is equipped with a lead screw, which is fitted with a nut. The nut is connected to the rotating shaft.
[0007] Furthermore, the lifting plate is provided with a guide block, the pedal is provided with a guide groove that cooperates with the guide block, and the guardrail is provided with a blocking block.
[0008] Furthermore, the lifting plate is provided with a positioning hole, and the first spring is installed in the positioning hole.
[0009] Furthermore, the guardrail is provided with a U-shaped block and a top block. A latch is slidably connected within the U-shaped block, and the latch passes through the top block. A second spring is fitted onto the latch, with one end of the second spring connected to the latch and the other end connected to the top block.

[0028] Example 1
[0029] See attached document Figure 1-8This application provides a construction scaffold, including an electric lifting assembly 1 for lifting. The electric lifting assembly 1 is remotely controlled for lifting. A lifting plate 2 is provided on the electric lifting assembly 1, and a plurality of first springs 3 are provided on the lifting plate 2. One end of each first spring 3 is fixedly connected to the lifting plate 2, and the other end is fixedly connected to a footboard 4. The footboard 4 serves as a working platform for construction workers. The footboard 4 is longitudinally slidably connected to the lifting plate 2, and the first springs 3 provide support. Initially, there is a certain distance between the footboard 4 and the lifting plate 2. When construction workers and building materials are on the footboard 4, and the total weight on the footboard 4 is not greater than the supporting force of the first springs 3, the first springs 3... The pedal 4 is supported to prevent it from falling. When the total weight on the pedal 4 exceeds the supporting force of the first spring 3 due to the increase in construction personnel and materials, the pedal 4 descends closer to the lifting plate 2. The greater the total weight on the pedal 4, the closer it descends to the lifting plate 2. A proximity sensor 5 is electrically mounted on the lifting plate 2 and electrically connected to the control board. The proximity sensor 5 is positioned between the lifting plate 2 and the pedal 4. When the pedal 4 bears weight, it descends closer to the lifting plate 2, causing the proximity sensor 5 to detect the pedal 4 and transmit a signal to the control board. The lifting platform 2 is equipped with a guardrail 6 and a safety door 7. The safety door 7 is hinged to the guardrail 6. The guardrail 6 is used to protect construction personnel from falling and to prevent construction tools and materials from falling. The safety door 7 is used for construction personnel to enter and exit the platform 4. The guardrail 6 is equipped with an alarm light 8, which is electrically connected to the control board. When the platform 4 is overloaded, the platform 4 descends and approaches the proximity sensor 5, causing the proximity sensor 5 to detect the platform 4. The proximity sensor 5 transmits a signal to the control board, which then issues an alarm command to the alarm light 8, causing the alarm light 8 to emit an overload alarm. During operation, the construction personnel carry a remote control for controlling the lifting of the electric lifting assembly 1 and open the safety door 7 to access the platform. Construction materials are placed on the pedal 4, and the electric lifting assembly 1 is raised using a remote control to position the construction platform for work. The electric lifting assembly 1 can move the platform into place according to the height of the work location, adapting to different heights and offering high efficiency. When the pedal 4 is overloaded, it compresses the first spring 3, causing it to descend and approach the proximity sensor 5. The proximity sensor 5 detects the pedal 4 and transmits a signal to the control board, which then issues an alarm command to the alarm light 8. The alarm light 8 emits an overload alarm to remind construction personnel, preventing accidents caused by overload, ensuring construction safety, and standardizing construction management. The first spring 3 also acts as a buffer.The design minimizes swaying during lifting and movement, reducing discomfort for construction workers and preventing material spillage. The structure is also well-designed.
[0030] Specifically, the electric lifting assembly 1 includes a lower base plate 9, lifting connecting rods 10, and an upper base plate 11. The lifting plate 2 is mounted on the upper base plate 11. Two sets of lifting connecting rods 10 are configured, each set consisting of several hinged links. The lower front ends of both sets of lifting connecting rods 10 are hinged to the upper part of the lower base plate 9, and the lower rear ends of both sets of lifting connecting rods 10 are slidably connected to the upper part of the lower base plate 9. The two sets of lifting connecting rods 10 together form a scissor mechanism. The lower front end of the upper base plate 11 is hinged to the upper part of the lifting connecting rods 10, and the lower rear end of the upper base plate 11 is slidably connected to the lifting connecting rods 10. The lifting connecting rods 10 are equipped with a rotating shaft 12, and the lower base plate 9 is equipped with a motor with a brake 13. The output end of the brake-equipped motor 13 is equipped with a lead screw 14, which is fitted with a nut 15. The nut 15 is connected to the rotating shaft 12. The brake-equipped motor 13 ensures braking in the event of sudden power outages or other emergencies, preventing the upper base plate 11 from falling rapidly and causing personal injury or property damage. During operation, the brake-equipped motor 13 drives the lead screw 14 to rotate, which in turn moves the nut 15 and the rotating shaft 12. The rotating shaft 12 is connected to the rear of the lower end of the lifting connecting rod 10. The forward movement of the rotating shaft 12 causes the rear of the lower end of the lifting connecting rod 10 to move towards the lower front, thus raising the upper base plate 11. Conversely, it lowers the upper base plate 11, achieving the lifting and lowering of the upper base plate 11. The structure is reasonable.
[0031] Specifically, the lifting plate 2 is provided with a guide block 16, and the pedal 4 is provided with a guide groove 17 that cooperates with the guide block 16 to guide the pedal 4, prevent shaking or jamming, and improve stability. The guardrail 6 is provided with a blocking block 18, which is located at the four corners to limit the pedal 4 to confirm its initial position. The blocking block 18 is also used to limit the safety door 7 internally, restricting the safety door 7 from being on the same side as the guardrail 6 after it is closed. The structure is simple.
[0032] Specifically, the lifting plate 2 is provided with positioning holes 19, and the number of positioning holes 19 corresponds one-to-one with the first spring 3. The first spring 3 is installed in the positioning holes 19 to guide the first spring 3 and improve stability.
[0033] Specifically, the guardrail 6 is provided with a U-shaped block 20 and a top block 21. A latch 22 is slidably connected inside the U-shaped block 20. The latch 22 is movably connected through the top block 21. A second spring 23 is sleeved on the latch 22. One end of the second spring 23 is connected to the latch 22, and the other end of the second spring 23 is connected to the top block 21. A ramp 24 is provided at the tail of the latch 22, and a handle 25 is provided at the head of the latch 22. When the door is closed or in normal condition, the second spring 23 pushes the latch 22 to extend a certain distance outside the guardrail 6, which is used to lock the safety door 7 after the door is closed, preventing the safety door 7 from opening automatically when not needed, so that personnel or materials can fall and injure people. When the door is closed, the safety door 7 moves inward along the ramp 24, squeezing the second spring 23 to retract. After the safety door 7 is in place, the second spring 23 pushes out the latch 22 to lock the safety door 7. The structure is simple.
[0034] Example 2
[0035] See attached document Figure 1-8 The difference between this embodiment and embodiment 1 is that the inner side of the guardrail 6 is provided with a tool storage rack 26 for storing construction tools, preventing tools from scattering and affecting construction, and the structure is reasonable.
[0036] Specifically, the lower base plate 9 is equipped with casters 27, which are installed under the lower base plate 9 for easy movement and transportation.
[0037] Specifically, the lower base plate 9 is also provided with a foot seat 28, which is threadedly connected to the lower base plate 9 for support, preventing the scaffold from running and affecting construction and safety during work.
[0038] Specifically, the pedal 4 is a patterned anti-slip iron plate, which serves to prevent slipping and deformation, thus ensuring its usability.
[0039] Specifically, the lifting plate 2 is provided with a clearance groove 29, and the proximity sensor 5 is installed in the clearance groove 29 to protect the proximity sensor 5 and prevent the pedal 4 from falling and damaging the proximity sensor 5. The structure is reasonable.

Any variations or substitutions that can be easily conceived by those skilled in the art within the technical scope disclosed in this utility model should be included within the protection scope of this utility model. The protection scope of this utility model should be determined by the protection scope of the stated claims.
