Embodiment 1

[0032] see figure 1 , figure 2 and image 3 , a liftable lifting device, including a base frame 1, a telescopic tube assembly and a motor 2 are vertically arranged on the base frame 1, the motor 2 is connected with a reel 3, the motor 2 can be directly connected with the reel 3, or can be connected through a reducer. A steel wire rope 4 is wound on the reel 3, and a baffle plate is provided at both ends of the reel 3 respectively. The baffle plate is disc-shaped and its diameter is larger than the outer diameter of the reel 3. Under the action of the two stoppers, the steel wire rope 4 is not easily wound to the outside of the drum 3 and can be stably wound on the drum 3 .

[0033] The telescoping tube assembly includes an outer tube 5 and at least one inner tube. An outer tube opening 501 is arranged on the tube wall of the outer tube 5. The length direction of the outer tube opening 501 is along the height direction of the outer tube 5. The upper end of the outer tube op...

Embodiment 2

[0043] The difference between this embodiment and embodiment one has the following two points: one is that the wheels 9 provided on the underframe 1 of the present embodiment are arranged on one side of the underframe 1, and there are two. The invention tilts toward the side where the wheels 9 are arranged, and then moves through the two wheels 9. Although it is inconvenient to move in this way, when not moving, the underframe 1 directly contacts the supporting ground, the contact area is large, and the support is more stable; It is equipped with a wireless control structure, through which the extension and shortening of the telescopic tube assembly can be remotely controlled, making it safer to use.

Embodiment 3

[0045] see Figure 10 , The difference between this embodiment and Embodiment 1 is that a reducer is provided between the motor 2 and the reel 3, and a foot-operated brake device 15 is installed on the reducer, and the foot-operated brake device 15 is an emergency stop device, when sudden situations such as the lifting plate 803 slipping suddenly occur, the foot-operated braking device 15 can be stepped on for emergency braking to reach the effect of the steel wire rope 4 on the braking drum 3 .

Abstract

The invention discloses a lifting type lifting device which comprises a bottom frame, a telescopic pipe assembly and a motor are vertically arranged on the bottom frame, the motor is connected with a winding drum, and a steel wire rope is wound on the winding drum; the telescopic pipe assembly comprises an outer pipe and at least one inner pipe, an outer pipe opening is formed in the pipe wall of the outer pipe, the length direction of the outer pipe opening is in the height direction of the outer pipe, the upper end of the outer pipe opening extends to the upper end of the outer pipe, an outer pipe mounting frame is arranged at the upper end of the outer pipe, and pulleys are arranged on the outer pipe mounting frame; and a lifting assembly is inserted into the upper end of the inner pipe on the innermost side, and the lifting assembly is used for placing a lifted object. The lifting type lifting device has the advantages of being small in size, convenient to carry and convenient to use, and also has the advantages of reducing labor intensity and being safe to use when used for auxiliary installation of objects such as a roller shutter door needing to be installed at a high position.

Description

technical field [0001] The invention relates to the field of lifting devices, in particular to a liftable lifting device. Background technique [0002] When installing the rolling door, it is necessary to install the rolled rolling door to the top of the door frame. Due to the heavy weight of the rolling door, manual lifting is not only labor-intensive but also dangerous. When the existing lifting device is used to assist in the installation of the rolling door, the labor intensity when installing the rolling door can be reduced, but it is necessary to use a sling to fasten the rolling door firmly, the operation is complicated, and the use is not convenient enough. The problem of inconvenient portability. For this reason, the applicant has proposed a liftable lifting device, which has the advantages of small size, easy to carry, easy to use, and reduced labor intensity. Contents of the invention [0003] The object of the present invention is to provide a liftable liftin...
