Abstract

An anti-tilting chain lifting device comprises a support, an upper gear shaft arranged at the upper part of the support, a lower gear shaft arranged at the lower part of the support, and at least two gears which are connected in series on the upper gear shaft and the lower gear shaft, wherein the upper gear shaft or the lower gear shaft is driven by an external driving device; the bearing frame and the anti-tilting device which can move along with the chain are fixedly arranged on the lifting chain, so that the mobility of the chain is not influenced, and the stability of bearing articles is ensured.

Description

Anti-tilting chain lifting device

Technical Field

The utility model relates to a elevating gear, concretely relates to anti-tilt chain elevating gear.

Background

The chain is a common power transmission mechanism and is often used for lifting and transporting articles, but because the chain is a flexible structure, an article bearing frame fixed on the chain is easy to incline and rotate when bearing heavy objects, so that the articles slide off the bearing frame, and the articles are damaged or personnel are injured.

SUMMERY OF THE UTILITY MODEL

In view of the above, an object of the present invention is to provide an anti-tilting chain lifter that can effectively prevent the article fixed on the chain from tilting and rotating.

In order to solve the above problem, the utility model discloses a technical scheme is: the chain lifting device comprises a support, an upper gear shaft arranged on the upper portion of the support, a lower gear shaft arranged on the lower portion of the support, and at least two gears which are connected in series on the upper gear shaft and the lower gear shaft, wherein the upper gear shaft or the lower gear shaft is driven by an external driving device, the position of the upper gear shaft on the upper gear shaft is the same as the position of the lower gear shaft on the upper gear shaft in the axial direction, a chain is sleeved between the gears which are on the upper gear shaft and the lower gear shaft in the same axial direction, a bearing frame capable of moving along with the chain is fixedly arranged on the chains on the left side and the right side, and an anti-tilting device is further arranged on the frame bearing.

Further, the frame bearing frame is fixed on the side edge of the chain through a chain connecting plate.

Furthermore, the anti-tilting device comprises fixed angle steel arranged on the inner side of the chain and a bearing support plate with rollers, and the rollers are tightly attached to the outer side of the fixed angle steel and can roll on the outer side of the fixed angle steel.

Furthermore, the bearing frame is an angle steel erected on the chain, and the bottom surface of the inner side of the bearing frame is used for bearing articles.

Further, the external driving device is a stepping motor or a servo motor which can be controlled by a program.

The utility model has the advantages and characteristics that the bearing frame and the anti-tilting device which can move along with the chain are fixedly arranged on the lifting chain, thereby not influencing the activity of the chain and simultaneously ensuring the stability of bearing articles.

Detailed Description

The present invention will be further explained with reference to the accompanying drawings:

referring to fig. 1, 2 and 5, an anti-tilting chain lifting device includes a bracket 1, an upper gear shaft 2 mounted on an upper portion of the bracket 1, a lower gear shaft 3 mounted on a lower portion of the bracket 1, and at least two gears 4 serially connected to the upper gear shaft 2 and the lower gear shaft 3, wherein the upper gear shaft 2 or the lower gear shaft 3 is driven by an external driving device (e.g., a programmable stepping motor or a servo motor), the positions of the gears on the upper gear shaft 2 in the axial direction are the same as the positions of the gears on the lower gear shaft 3 in the axial direction, a chain 5 is sleeved between the gears on the upper gear shaft 2 and the lower gear shaft 3 in the axial direction, and a bearing frame 6 capable of moving along with the chain is fixedly arranged on the chains on the left and right sides.

Referring to fig. 2 to 4, the chain 5 itself is considered to be of a flexible structure. In order to prevent the carrier 6 from tilting and rotating when carrying the articles, which would cause the articles to slip off the carrier 6, the frame carrier 6 is also provided with an anti-roll device 7. Specifically, the anti-roll device 7 comprises a fixed angle iron 71 arranged on the inner side of the chain and a bearing support plate 73 with a roller 72, the roller 72 is tightly attached to the outer side of the fixed angle iron 71 and can roll on the outer side of the fixed angle iron 71, and the roller 72 can limit the tilting and the rotation of the bearing 6 and does not influence the movement of the bearing 6 along with the chain.

Bear frame 6 for erect the angle steel on the chain (only show the angle steel on right side in fig. 2, its opposite left side also is provided with the angle steel, both sides angle steel form the bearing frame together, see specifically fig. 6), its inboard bottom is used for bearing article, in order to prevent that frame bears frame 6 from hindering the operation of chain self, frame bears frame 6 and passes through chain connecting plate 51 and fix on the side of chain, and frame bears frame 6 and the positive certain distance that keeps of chain like this, guarantees that the chain has certain activity space and does not influence the operation of self.

In the description of the present invention, it should be noted that the terms "center", "upper", "lower", "left", "right", "vertical", "horizontal", "inner", "outer", and the like indicate orientations or positional relationships based on the orientations or positional relationships shown in the drawings, and are only for convenience of describing the present invention and simplifying the description, but do not indicate or imply that the device or element referred to must have a specific orientation, be constructed in a specific orientation, and be operated.
