Technical Field

The utility model relates to a lift platform field specifically is a stand lift platform.

Background

The lifting platform is a multifunctional hoisting loading and unloading mechanical device and can be divided into a fixed type and a movable type, wherein the movable type comprises a straight arm type, a crank arm type, a scissor fork type, a mast type and the like. The lifting platform is used as lifting equipment used in building and production and manufacturing, and is generally powered by a motor to carry the whole device to work. The most common lifting platform is a scissor-type lifting platform, and a motor drives a cross rod to move, so that the life of the lifting platform is realized. The common upright post lifting platform adopts a steel pipe and utilizes the transmission of a gear and a rack to convert the carrying motion into linear reciprocating motion, but the manufacture is inconvenient because the gear and the rack are adopted, and the unstable motion condition easily occurs when the rack moves upwards due to the limitation of the motion height.

SUMMERY OF THE UTILITY MODEL

An object of the utility model is to provide a stand lift platform to solve the problem that proposes among the above-mentioned background art.

In order to solve the technical problem, the utility model provides a following technical scheme: an upright column lifting platform comprises a base, wherein a hollow supporting tube is fixedly arranged at the upper end of the base, and a vertically arranged sliding groove is formed in the outer side of the supporting tube;

a screw rod is arranged in the supporting tube, the bottom of the screw rod extends into the base,

a motor is fixedly arranged in the base, and the output end of the motor is connected with the screw rod and used for driving the screw rod to rotate;

the elevating platform is further installed on the outer side of the supporting pipe, a sliding block matched with the sliding groove is fixedly arranged on the elevating platform, threads matched with the screw rod are formed in the inner side wall of the elevating platform, and the screw rod can drive the elevating platform to move up and down.

Preferably, a side door is arranged on the side surface of the lifting platform, and a stair is fixedly arranged right below the side door.

Preferably, the upper end of the base is also fixedly provided with a supporting column.

Preferably, the inner side of the base is fixedly provided with an inner box body, and the upper end of the base is provided with a counterweight port communicated with the inner box body.

Preferably, the upper end of the supporting tube is welded with a hanging ring.

Compared with the prior art, the beneficial effects of the utility model are that:

the utility model discloses a set up lead screw, stay tube, spout and elevating platform isotructure, have the lead screw to take the elevating platform motion, relatively more steady during the motion, adopt the transmission structure of screw thread moreover, can transmit bigger weight.

In addition, the lead screw is arranged in the supporting pipe, the overall height is not additionally increased, the supporting part is kept still in the upward movement process of the lifting platform, and compared with a mode that the rack moves upwards, the extending end of the rack is more and more in the upward movement process, so that the contact part between the rack and the whole device is less, and the unstable condition is easy to occur.

Detailed Description

The technical solutions in the embodiments of the present invention will be described clearly and completely with reference to the accompanying drawings in the embodiments of the present invention, and it is obvious that the described embodiments are only some embodiments of the present invention, not all embodiments. Based on the embodiments in the present invention, all other embodiments obtained by a person skilled in the art without creative work belong to the protection scope of the present invention.

Referring to fig. 1-2, the present embodiment provides an upright lifting platform, which includes a base 1, wherein the base 1 is made of metal material, and has a supporting function for the entire device, so that the device is more stable in use. The upper end fixed mounting of base 1 has hollow stay tube 8, and the internally mounted of stay tube 8 has lead screw 10, and the bottom of lead screw 10 stretches into the inside of base 1, and the inside fixed mounting of base 1 has motor 11, and motor 11's output and lead screw are connected, and motor 11 can take lead screw 10 to rotate, provides power for lead screw 10.

The inside of base 1 still installs supporting seat 2, and supporting seat 2 is located the bottom of lead screw 10 to with the bottom contact of lead screw 10, have the effect of support to lead screw 10.

The outer side of the supporting tube 8 is provided with a chute 7 which is vertically arranged;

the outer side of the supporting tube 8 is also provided with a lifting platform 6, a sliding block matched with the sliding groove 7 is fixedly arranged on the lifting platform 6, and the lifting platform 6 can slide up and down in the sliding groove 7.
