Description

Technical Field

[0001] The utility model relates to the technical field related to elevators, in particular to a movable remote-controlled maintenance elevator. Background Art

[0002] With the continuous improvement of the level of industrialization, the application of various equipment in production and life is becoming more and more popular. Scissor lifts, as lifting mechanical equipment, are widely used in various aerial work projects. Its scissor-type mechanical structure makes the lifting platform have higher stability, a wide working platform and a higher carrying capacity, making the aerial work range larger and suitable for multiple people to work at the same time.

[0003] The utility model patent with announcement number CN212151512U discloses a fixed scissors-type lift, which belongs to the technical field related to the manufacture of auxiliary equipment for aerial work. It solves the problem in the prior art that the traditional scissors-type lift only relies on a single-layer scissors-type mechanism to provide vertical support for the lifting platform. However, when there is a large load on the lifting platform, the scissors-type structure is over-stressed, and the lifting platform lacking sufficient support is very prone to swaying accidents. The single scissors-type structure is also very prone to deformation and fracture accidents, posing a serious safety threat. The base includes a base, one end of the base is provided with two lower guide grooves, and lower guide blocks are slidably installed in the two lower guide grooves. The two lower guide blocks are pin-connected to two primary support rods on the other end of the base, and the upper ends of the two primary support rods are pin-connected to secondary support rods. Telescopic side panels are vertically welded at both ends of the base, and sliding grooves are correspondingly provided on the two telescopic side panels. A lifting platform is horizontally arranged between the two telescopic side panels. The utility model cross-arranges a primary support rod and a secondary support rod that are rotatably connected between the lifting platform on the base, and arranges a side beam, a middle beam and a cross beam between the primary support rod and the secondary support rod to facilitate the connection of a hydraulic cylinder arranged on the base. The primary support rod and the secondary support rod are pulled and supported by a retractable hydraulic rod, so as to drive the lifting platform to slide smoothly in the vertical direction between the two side panels, thereby realizing smooth lifting.

[0004] However, the above patent still has shortcomings: the patent adopts a scissor-type telescopic rod for lifting, which causes one side of the elevator to be suspended while the lifting frame is rising, thereby reducing the pressure resistance of the suspended side of the elevator, which is prone to safety accidents.

[0026] like Figure 4 As shown, the telescopic mechanism 14 includes: a fixed rod 15 is arranged between the two second linkage rods 9, and the two ends of the fixed rod 15 are respectively fixedly connected to the second linkage rod 9, and a hydraulic cylinder 16 is arranged on one side of the fixed rod 15, and the telescopic end of the hydraulic cylinder 16 is fixedly connected to a collar 17, and the collar 17 is sleeved on the outer surface of the fixed rod 15; a first connecting block 18 is fixedly connected to the side of the hydraulic cylinder 16 away from the collar 17, and a rotating shaft 19 is fixedly connected to the inside of the first connecting block 18, and the outer surfaces of both ends of the rotating shaft 19 are rotatably connected to the second connecting blocks 20, and the bottoms of the second connecting blocks 20 are connected to the connecting The rod 21 is fixedly connected, and both ends of the connecting rod 21 are fixedly connected to the bottom frame 1.

The remote control mechanism has the function of controlling the telescopic end of the hydraulic cylinder 16 to extend and retract by a remote controller. The remote control mechanism adopts the existing structure and will not be described in detail. The telescopic end of the hydraulic cylinder 16 extends outward while pushing the fixed rod 15 through the collar 17. At the same time, the hydraulic cylinder 16 drives the first connecting block 18 to rotate inside the two second connecting blocks 20 with the rotating shaft 19 as the center, so that the fixed rod 15 drives the second linkage rod 9 to rotate with the second fixed frame 5 as the center.

[0027] like Figure 3 As shown, two auxiliary rods 22 are arranged between the first linkage rod 8 and the third linkage rod 10. The two ends of the two auxiliary rods 22 are rotatably connected to the first linkage rod 8 and the third linkage rod 10 respectively. The first linkage rod 8 can be pulled by the auxiliary rod 22 to rotate with the first fixed frame 4 as the center while the second linkage rod 9 rotates, and the elevator can perform vertical lifting and lowering movements to avoid tilting or shaking.

[0032] The user can enter the top frame 2 and then close the box door 24 on one side of the guardrail 23, which improves the safety performance of the elevator, reduces the probability of workers falling when performing high-altitude operations on the elevator, and thus improves practicality.
