Description

Technical Field

[0001] The present invention relates to the technical field of elevators, and particularly to a safety guardrail device for an elevator that is easy to assemble. Background Art

[0002] The scissor lift is a special equipment for high-altitude operations with a wide range of uses. Its scissor mechanical structure provides high stability for the lifting of the lift table. The wide working platform and high load-bearing capacity enable a larger range of high-altitude operations and are suitable for multiple people to work simultaneously. It makes the work more efficient and safer. There are many types of scissor lifts, mainly including: fixed scissor type, self-propelled scissor type, vehicle-mounted scissor type, and manually towed type.

[0003] In the prior art, the guardrail structures of fixed scissor lifts are divided into two types: one is a fixed type, that is, the guardrail is directly welded to the tabletop, which has the characteristics of good stability and high reliability, but the guardrail in this way is not detachable; the other is a detachable type, that is, the connection between the guardrail and the tabletop is realized through bolts. However, due to the use of bolts and nuts for fixation, the disassembly and assembly steps of the guardrail and the tabletop are too cumbersome, so the entire disassembly and assembly process is time-consuming and laborious, which has a certain impact on the subsequent work of the staff.

[0033] In this embodiment, the disassembled fixing bolt 22 can be stored by using the placement box 26, so as to avoid the fixing bolt 22 from being lost.

[0034] The working principle and use process of the present invention:

[0035] When in use, the staff first erects the front and rear transverse protective plates 12 from under the elevator pedal 1, and then erects the left longitudinal protective plate 13 from under the elevator pedal 1, so that the positioning plates 7 on the front and back of the left longitudinal connecting plate 5 are respectively inserted into the connecting grooves 6 opened inside the front and rear transverse connecting plates 4, so that the clamping block 10 at the bottom end of the first telescopic sleeve rod 9 is in contact with the top of the positioning plate 7, thereby completing the fixation of the positioning plate 7 and the connecting groove 6, and the front and back mounting plates 17 of the left longitudinal plug-in plate 16 are respectively inserted into the plug-in grooves 18 opened inside the front and rear transverse plug-in plates 15, when the plug-in interface 19 opened on the upper surface of the mounting plate 17 is opposite to the opening of the positioning groove 23, the fixing bolt 22 is placed in the positioning groove 23, and the fixing bolt 22 is pushed through the positioning groove 23 under the gravity factor. The slot 23 is inserted into the plug-in slot 18, and the bottom end of the fixing bolt 22 contacts the placement plate 21, pulling the movable plate 25 so that the movable plate 25 moves along the positioning slot 23, thereby causing the bottom of the movable plate 25 to collide with the top of the fixing bolt 22, so that the movable plate 25, the fixing bolt 22 and the mounting plate 17 form a fixed state, thereby completing the fixation of the mounting plate 17 and the plug-in slot 18, so that the front and rear transverse protection plates 12 and the left longitudinal protection plate 13 form a complete circular guardrail plate; at this time, the staff climbs onto the elevator pedal 1, and other staff members erect the right longitudinal protection plate 13 from the bottom of the elevator pedal 1, so that the positioning plates 7 on the front and back of the right longitudinal connecting plate 5 are respectively inserted into the connecting slots 6 opened in the front and rear transverse connecting plates 4, and the right longitudinal plug-in plate 16 The front and back mounting plates 17 are respectively inserted into the plug-in slots 18 provided inside the front and rear transverse plug-in plates 15, and the same operation is performed again, so that the circular guardrail plate is connected to the longitudinal protective plate 13 on the right side, thereby assembling a complete surrounding guardrail.

[0036] In summary, for the safety guardrail device for the elevator that is easy to assemble, by setting the bottom connection device 2, the protection device 11, and the top plug-in device 14, the automatic resilience of the springs on the first and second telescopic rods 20 is utilized to prompt the bottom connection device 2 and the top plug-in device 14 to drive the two transverse guard plates 12 and the two longitudinal guard plates 13 to fit together to form a complete guardrail. Moreover, the entire disassembly and assembly process only requires toggling the movable plate 25, which makes the disassembly and assembly steps of the guardrail and the tabletop more convenient and fast, saving time and effort in the whole disassembly and assembly process. By setting the movable shaft 3, the two transverse guard plates 12 and the two longitudinal guard plates 13 can be rotated under the elevator pedal 1, making the elevator pedal 1 become an unobstructed platform when not in use, further improving the practicality of the elevator. In addition, the two transverse guard plates 12 and the two longitudinal guard plates 13 can wrap and shield the internal structure of the elevator, improving the overall integrity of the structure and thus beautifying the appearance of the elevator.
