Description

Technical Field

[0001] This utility model relates to the field of elevator technology, specifically an elevator with a safety protection device. Background Technology

[0002] Construction elevators are often called construction hoists, but the definition of construction hoists is broader. Construction platforms also belong to the construction hoist series. A simple construction elevator consists of several parts, including a car, drive mechanism, standard sections, wall attachments, chassis, railings, and electrical system. It is a commonly used construction equipment for carrying people and goods in construction.

[0003] Currently, in the use of elevators, due to their simple structure, the upper guardrails are fixed, making it inconvenient to adjust the height of the guardrails according to usage needs. This results in limited safety protection performance and reduced efficiency. In addition, existing elevators are designed for easy movement via a movable chassis at the bottom, making it difficult to fix them completely during construction. This leads to the risk of the elevator shifting during construction, making it inconvenient to use. Therefore, we propose an elevator with a safety protection device. Utility Model Content

[0016] Compared with the prior art, the beneficial effects of this utility model are:

[0017] 1. The elevator with safety protection device allows the first and second protective shells to slide vertically relative to each other. A second motor, in conjunction with a second lead screw, drives a second push plate to move a support rod vertically, thereby moving a second support sleeve. This allows the second protective shell to slide vertically with the support of the second support sleeve, adjusting the overall height of the guardrail. This makes it easy to adjust the height of the guardrail according to usage needs, resulting in high safety protection performance and improved efficiency of the elevator.

[0018] 2. The lifting platform with safety protection device drives the first lead screw to rotate through the first motor, which in turn drives the first push plate that restricts rotation to push the support sleeve downward in conjunction with the push rod. This causes the support sleeve to work with the foot pads to support the entire base, and the electric mobile chassis body to be suspended in the air, thus completing the fixation. This makes it easy to completely fix the lifting platform during construction, avoiding the risk of the lifting platform moving during construction, and making it easy to use.

[0037] In summary, the first protective shell 300 and the second protective shell 400 can slide up and down relative to each other. The second motor 340, in conjunction with the second lead screw 350, drives the second push plate 360 ​​to push the support rod 370 to move up and down, thereby pushing the second support sleeve 380 to move up and down. This allows the second protective shell 400 to slide up and down with the support of the second support sleeve 380, adjusting the overall height of the guardrail. This makes it easy for the elevator to adjust the height of the guardrail according to usage needs, resulting in high safety performance and improved efficiency of the elevator.

[0038] In summary, the first motor 150 drives the first lead screw 160 to rotate, which in turn drives the first push plate 170, which restricts rotation, to push the support sleeve 190 downward in conjunction with the push rod 180. This causes the support sleeve 190 to work with the foot pad 191 to support the base 100 and suspend the electric mobile chassis body 111 in the air, thus completing the fixation. This makes it easy to completely fix the elevator during construction, avoiding the risk of the elevator moving during construction and making it convenient to use.

[0039] In practical use, those skilled in the art first manually operate the control panel of the elevator to start the first motor 150. The first motor 150 drives the first lead screw 160 to rotate, which drives the first push plate 170, which restricts rotation, to cooperate with the push rod 180 to push the support sleeve 190 downward and move it out of the storage slot 120. The paper support sleeve 190, carrying the foot pad 191, contacts the ground and supports the base 100 in the opposite direction, causing the electric moving chassis body 111 to be suspended in the air. Then, the latch 430 is slid upward to open the door 420 and climb onto the first protective shell 300. Then, the door 420 is closed and the latch 430 is inserted back into the socket 410. Next, the control panel of the elevator is operated again to start the second motor 340. Then, the second motor 340 drives the second lead screw 350 to rotate, which drives the second push plate 360 ​​to cooperate with the support rod 370 to push the second support sleeve 380 and the second protective shell 400 upward until the second protective shell 400 reaches the specified height.
