Problems solved by technology

[0003] The lifting speed of the current lifting device is often determined by the driving equipment. For example, the Chinese patent application number is 201520903475.1, which discloses a rapid lifting device for road and bridge construction tools. Areas, in order to improve work efficiency, often need high-power drive equipment, the cost is high, and the general drive equipment has a fixed lifting speed, which is not practical enough and needs to be optimized

Embodiment 1

[0024]Such asFigure 1-4 The bridge construction lifting device, including a base 1, and a fixed column 4 and a rotary electric machine 16 are fixed to the upper end of the base 1, and the fastening sheet 8 is fixedly mounted, and the fixing plate 8 is on one side. A plurality of first pullers 9 are mounted, and the first pulley 9 is mounted, and a lifting mechanism 10 is mounted above the sling 11, and the lifting mechanism 10 is disposed within the fixed column 24, the rotary electric machine. 16 The output is fixed to the shaft 14, the outer sleeve of the rotating shaft 14 with a fixed disk 15 thereof, and the sling 11 is connected to the fixed disk 15, and the other end is connected to the hanging basket 13, when the rotating motor 16 rotates When the fixing plate 15 is rotated, it is contracted or elongated with a hanging rope 11. When shrinkage, the hanging basket 13 of the other end of the hanging rope 11 will be lifted in the article in the hanging basket 13, and when the ite...

Embodiment 2

[0028]This example is further optimized on the basis of Example 1, such asFigure 5-7As shown, the first tapered gear 2 is rotated from the rotating shaft 14, the rotating shaft 14 is mounted from one end of the rotary electric machine 16 to control the clutch mechanism of the first tapered gear 2, i.e., by providing a clutch mechanism to the first cone. Whether the shaped gear 2 is fixed to the rotating shaft 14 to control the lifting speed according to the usage, more practical efficient.

[0029]Further, the clutch mechanism includes a telescopic motor 29 that is fixedly mounted on the rotating shaft 14, and the output of the telescopic motor 29 is fixedly mounted, and the sleeve 28 is set outside the rotary shaft 14. And slide it with it, in order to facilitate the installation of the clutch mechanism, the limit slot 23 in which the clutch mechanism is mounted in the fixed column 4, and the first tapered gear 2 is opened, and the positioning groove 25 is provided. The slider 25 is m...

Abstract

The invention relates to a lifting device for bridge construction, belonging to the technical field of bridge equipment, comprising a base, a fixed column and a rotating motor are installed on the upper end of the base, a fixed plate is installed on the upper end of the fixed column, and a plurality of first pulleys are installed on one side of the bottom of the fixed plate , a sling is installed above the first pulley, a lifting mechanism is installed above the sling, a rotating shaft is installed at the output end of the rotating motor, and a fixed plate is installed outside the rotating shaft, one end of the sling is connected with the fixed plate, the other end is connected with the hanging basket, One end runs through the fixed column and is connected with the lifting mechanism; the present invention adjusts the distance between the second pulley and the first pulley synchronously during the process of shrinking and extending the suspension rope by setting the lifting mechanism, thereby realizing the lifting speed. The adjustment improves the working efficiency, and the working state of the clutch mechanism and the lifting mechanism is set to control, so as to control the lifting speed according to the usage situation, with strong selectivity, more practical and convenient.

Description

Technical field[0001]The present invention relates to the technical field of bridge equipment, and is specifically a bridge construction lifting device.Background technique[0002]Bridge, generally finger hosted in the sea of ​​rivers and lakes, making the vehicle pedestrian such as a structure. In order to adapt to the transportation industry of modern high-speed development, the bridge is also attracted to enabling more convenient buildings across the mountain, bad geology or satisfying other transportation needs. The bridge needs to be delivered to the construction site in construction construction, and as the change in construction is often necessary to use the corresponding lifting device.[0003]The current improvement device is often decided to drive equipment, such as China Patent Application No. 201520903475.1 Publicly enhanced road bridge construction tool rapid lifting device, which transports road bridge construction to high-level construction by rapidly hoisting the motor. ...
