[0020] Example: Figure 1-4 As shown, the present invention is a roller type elevator, including a lifting base 1, a lifting support platform 2 is installed on the lifting base 1, and the lifting support platform 2 is connected to the lifting rod of the lifting base 1, a positioning platform 3 is arranged in parallel on the lifting support platform 2, and the positioning platform 3 and the lifting support platform 2 are movably connected through a positioning rod 11, a guardrail box 4 is installed on the surface of the positioning platform 3, and a roller platform 5 is arranged at the bottom of the guardrail box 4, the roller platform 5 is movably arranged on the surface of the positioning platform 3, and the positioning platform 3 and the lifting support platform 2 are connected through a stabilizing device.

[0021] Among them, the stabilizing device includes a resistance rod 10, a support rod 12, a telescopic rod 14 and a movable sleeve 13. The movable sleeve 13 is movably mounted on the positioning rod 11. The two ends of the resistance rod 10 are movably arranged on the surfaces of the positioning platform 3 and the lifting support platform 2 respectively. The resistance rod 10 and the movable sleeve 13 are connected by the telescopic rod 14. The resistance rod 10 is arranged between the lifting support platform 2 and the positioning platform 3 so that the positioning platform 3 and the lifting support platform 2 are stably connected.

[0022] Among them, two positioning rods 11 are arranged on both sides of the positioning platform 3, and one end of the positioning rod 11 is movable through the lifting support platform 2 and is fixedly connected to the bottom of the positioning platform 3. The resistance rod 10 is arranged between the positioning rods 11, and the resistance rod 10 is connected to the movable sleeve 13 on the same side. The two resistance rods 10 are respectively rotatably connected with support rods 12, and the other end of the support rod 12 is rotatably connected to the bottom of the positioning platform 3. When the resistance rod 10 is connected, the support rod 12 increases stability.

[0023] Among them, sliding grooves are respectively provided on the side surfaces close to each other on the positioning platform 3 and the lifting support platform 2, and the two ends of the resistance rod 10 are respectively slidably connected in the sliding grooves. The resistance rod 10 includes a sub-rod and a mother rod. An opening is provided at one end of the mother rod, and the sub-rod is movably inserted into the mother rod through the opening and is connected to the bottom of the mother rod through a spring. The resistance rod 10 has the same structure as the telescopic rod 14. The resistance rod 10 and the telescopic rod 14 with elastic function can prevent the lifting base 1 from shaking due to the shaking of the guardrail box 4 after the elevator rises to a certain height.

[0024] The surface of the positioning rod 11 is movably wound with a tension spring, and the tension spring is respectively contained at the upper and lower ends of the movable sleeve 13. The positioning rod 11 plays a positioning role and also has a shock-absorbing role.

[0025] Among them, two moving grooves 15 are opened on the positioning platform 3, and the moving groove 15 is slidably connected with an elastic support 6, one end of the elastic support 6 is fixedly connected to the bottom of the roller platform 5, and the other end of the elastic support 6 is installed with a pulley 16, and the pulley 16 is slidably set in the moving groove 15. When the roller platform 5 moves, it can move according to the specified track.

[0026] Among them, one end of the positioning platform 3 is fixedly connected to two mounting plates 8, and a driving motor 9 is installed on the mounting plate 8. The output shaft of the driving motor 9 is fixedly connected to a silicone leather wheel, and the silicone leather rollers are respectively arranged at the bottom of the roller platform 5 and contact with the bottom of the roller platform 5. A rubber anti-slip strip 7 is installed at one end of the roller platform 5. When the roller platform 5 contacts the ground, it can be more stable and the friction is increased.

[0027] Among them, an opening is opened on one side of the guardrail box 4, and a box door 17 is installed at the opening to facilitate unloading through the roller platform 5.

[0028] Working principle: When using this device, when the lifting base 1 raises the lifting support platform 2 to a certain height, the driving motors 9 on both sides are started, so that the driving motors 9 drive the roller platform 5 to slide out of the bottom of the guardrail box 4, and then contact the layer board of the next floor, and directly and stably on the surface of the layer board, and the anti-slip strip 7 at the bottom plays an anti-slip role, and then the box door 17 is opened, and the goods to be transported can be directly transported to the designated floor through the roller platform 5, without the need for manual back and forth transportation, and the bottom is provided with a resistance rod 10 and a positioning rod 11 with elastic function, which can play an elastic supporting role between the positioning platform 3 and the lifting support platform 2. When the positioning platform 3 supports the resistance rod 10, the resistance rod 10 is separated by the two support rods 12 connected by rotation, and the resistance rod 10 slides in the slide groove, and then the support rod 12 supports the resistance rod 10, relieves the surface pressure, and plays a shock-absorbing and buffering effect.
