The utility model discloses a lifting column which comprises a column body, wherein a cable rope pulley is arranged in the middle of the column body, a semicircular arc clamping groove is formed in the surface of the cable rope pulley, an arc-shaped buckle is further arranged above the cable rope pulley, the arc-shaped buckle is fixed with the column body through a support, and the vertical height of the arc-shaped buckle and the support is adjustable. After the cable is wound, the arc buckle can be downwards regulated, the arc buckle and the semicircular arc clamping groove form a round buckle, and the cable is buckled in the round buckle, so that a stress point at the top can be prevented from being separated from the arc clamping groove when the cable swings, and the whole cable can be prevented from being separated from the clamping groove in the swinging process as long as the top is prevented from being separated from the arc clamping groove, and the cable is prevented from being difficult to pull out in a gap between the hanging head and the cable pulley after being separated.

Description

Lifting column

Technical Field

The utility model relates to the technical field of hoisting mechanical parts, in particular to a hoisting column.

Background

The lifting column is used for fixing a cable of a lifting device and is arranged at the bottom of a lifting head, but in the high-altitude lifting process, the cable cannot swing easily due to the reasons of swing, wind power and the like, so that the cable is separated from a cable pulley and is clamped in a gap between the cable pulley and the lifting head, and the cable is pulled by a heavy object and is woven by steel wires, so that the cable is difficult to pull out.

Disclosure of Invention

The utility model aims to provide a lifting column for solving the technical problems in the background technology.

The technical scheme of the utility model is as follows:

the utility model provides a lift by crane post, includes the cylinder, has the cable rope sheave at cylinder mid-mounting, and the semicircle draw-in groove has been seted up on the surface of cable rope sheave, still is provided with the arc buckle above the cable rope sheave, the arc buckle passes through the support to be fixed with the cylinder, and the arc buckle is adjustable with the vertical height of support.

Further, the fixed screw holes are formed in the two sides of the arc-shaped buckle, adjusting screws are arranged at the tops of the supports, and the adjusting screws penetrate into the fixed screw holes to be matched with nuts to fix the lug plates with the supports.

Further, both sides of the cable wheel are provided with flanges A, the support consists of a flange B and a rod seat fixed at the top of the flange B, the middle part of the flange B is provided with a shaft hole, and the flanges A and B are fastened through bolts.

Further, a bridge plate is arranged between the arc-shaped buckle and the lug plate for connection.

Further, both sides of the flange B and the rod seat are in arc transition.

Further, the bridge plate is connected to the upper portion of the arc-shaped buckle, and the bottom end face and the top end face are in arc transition connection with the arc-shaped buckle.

The utility model has the advantages that:

after the cable is wound, the arc buckle can be downwards regulated, the arc buckle and the semicircular arc clamping groove form a round buckle, and the cable is buckled in the round buckle, so that a stress point at the top can be prevented from being separated from the arc clamping groove when the cable swings, and the whole cable can be prevented from being separated from the clamping groove in the swinging process as long as the top is prevented from being separated from the arc clamping groove, and the cable is prevented from being difficult to pull out in a gap between the hanging head and the cable pulley after being separated.

Drawings

FIG. 1 is a schematic perspective view of the present utility model;

fig. 2 is a front view of the present utility model.

In the figure: the cable pulley comprises a 1-column body, a 2-cable pulley, a 21-semicircular clamping groove, a 3-flange A, a 4-cambered buckle, a 41-bridge plate, a 42-lug plate, a 5-support, a 51-flange B, a 52-rod seat, a 6-adjusting screw, a 61-nut and a 7-bolt.

Detailed Description

The following describes the embodiments of the present utility model further with reference to the drawings. The description of these embodiments is provided to assist understanding of the present utility model, but is not intended to limit the present utility model. In addition, the technical features of the embodiments of the present utility model described below may be combined with each other as long as they do not collide with each other.

As shown in fig. 1-2:

the utility model provides a lifting column, includes cylinder 1, has cable rope sheave 2 at cylinder 1 mid-mounting, and semicircle draw-in groove 21 has been seted up on the surface of cable rope sheave 2, still is provided with arc buckle 4 in cable rope sheave 2 top, arc buckle 4 is fixed with cylinder 1 through support 5, and arc buckle 4 is adjustable with the vertical height of support 5.

According to the utility model, after the cable is wound, the arc-shaped buckle 4 can be downwards regulated, the arc-shaped buckle 4 and the semicircular clamping groove 21 form a round buckle, and the cable is buckled in the round buckle, so that a stress point at the top can be prevented from being separated from the circular clamping groove when the cable swings, and the whole cable can be prevented from being separated from the clamping groove in the swinging process as long as the top is prevented from being separated from the circular clamping groove, and the cable is prevented from being difficult to pull out in a gap between the hanging head and the cable wheel 2 after being separated.

In order to conveniently adjust arc buckle 4, arc buckle 4 both sides set up otic placode 42, all offered fixed screw on the otic placode 42, and support 5 top all is provided with adjusting screw 6, adjusting screw 6 penetrates fixed screw interior cooperation nut 61 and fixes otic placode 42 and support 5, and this kind of structure still does benefit to and dismantles arc buckle 4.

For the convenience of processing and installation etc., both sides of cable pulley 2 all are provided with flange A3, support 5 comprises flange B51 and the fixed pole seat 52 in flange B51 top, the shaft hole is seted up at flange B51 middle part, flange A3 and flange B51 pass through bolt 7 fastening, that is to say support 5 and cylinder 1 are the separation detachable, can process the back and assemble alone, because flange A3's setting makes arc buckle 4 both ends far away pole seat 52, can be provided with bridge 41 connection between arc buckle 4 and otic placode 42, flange B51 and pole seat 52 both sides all adopt arc transition, convenient processing.

Meanwhile, the bottom end of the buckle is relatively close to the cable wheel 2, so that the bridge plate 41 is connected to the upper portion of the arc buckle 4, the bottom end face and the top end face are in arc transition connection with the arc buckle 4, and the height of the rod seat 52 is properly increased.

The embodiments of the present utility model have been described in detail above with reference to the accompanying drawings, but the present utility model is not limited to the described embodiments.
