Description

Rack elevator

Technical Field

The utility model belongs to the technical field of machinery and specifically relates to a rack lift is related to.

Background

Most of the conventional rack elevators in the market commonly use a single lifting gear, have single acting point, and easily wear the rack part on the lifting rod, so that the service life of the rack elevators is short, and the maintenance cost is high.

Another kind of rack lift commonly used sets up the promotion gear structure for both sides, and the promotion gear that needs to be located the both sides of rack symmetry rotates with fast simultaneously, and the precision and the degree of accuracy that need are very high, and though its atress is more even, its cost of manufacture is very high, and the error of a bit will lead to the promotion gear rotation inconsistent of rack both sides to lead to the rack both sides because of the uneven deformation of atress, even fracture.

Disclosure of Invention

The utility model aims to solve the problem that to the shortcoming among the above-mentioned prior art, put forward improvement scheme or alternative, especially a balanced effort, postpone rack elevator's life's improvement or alternative.

In order to solve the above problem, the utility model discloses a scheme as follows: a rack elevator comprising: the lifting mechanism comprises a gear box, a mounting frame and a lifting rod, wherein the gear box is mounted on the mounting frame and comprises a gear mounting part and a lifting rod mounting part, a climbing gear is arranged at the output end of the gear box, the lifting rod is arranged in the lifting rod mounting part, a rack is arranged on the lifting rod, and the climbing gear is meshed with the rack; the transmission wheel is arranged on the outer side of the gear box, and the transmission gear is arranged in the gear box and is connected with the transmission wheel through a transmission rod; the transmission gear is meshed with the climbing gear; the two climbing gears are symmetrically arranged at the upper and lower positions of the transmission gear; the gear box is provided with a mounting groove, a mounting hole and a mounting rod, the mounting hole and the mounting groove are symmetrically arranged, the climbing gear is arranged on the mounting rod, and the mounting rod penetrates through the mounting hole and is arranged in the mounting groove; and a packaging plate is arranged outside the mounting hole.

Further, according to above-mentioned design the rack lift, characterized in that, gear box and mounting bracket are the integrated into one piece structure.

Further, according to above-mentioned design scheme rack lift, its characterized in that, four angles of mounting bracket are equipped with the mounting hole respectively.

Further, according to the above design scheme, the rack elevator is characterized in that a slide rail is arranged on the inner wall of the lifting rod installation part, and the slide rail is matched with the lifting rod.

Further, according to the above design scheme, the rack elevator is characterized in that an oil injection port is formed in the gear box and used for injecting lubricating oil into the gear box.

The technical effects of the utility model are as follows: this application has adopted the transmission between two parties, and the gear that climbs from top to bottom has taken an effect jointly for there are two impetus with the rack simultaneously in the gear that climbs, and it is more even to let the rack atress, lets the rack can receive the effort at two points when rising or putting off the shelf, makes the lifter move more steadily in the slide rail, thereby reduces its wearing and tearing, delays its life. Two gear settings that climb are in the same one side of rack to by same drive gear provides power, thereby guaranteed that two gear rotational speeds that climb are unanimous, and because two gear settings that climb are in the same one side of rack, even if consequently, because the gear that climbs is become flexible, wearing and tearing etc. cause the error, can not cause the rack to warp, and is not high to the difficulty of manufacturing process.
