Description

Pipeline maintenance device capable of vertical and turning operation

technical field

The utility model relates to a transport lifting device, in particular to a pipeline maintenance device such as a flue.

Background technique

At present, the converter flue maintenance equipment (also known as the flue maintenance device) in my country's steel mills generally uses the form of a mobile trolley. That is, through the hook of the trolley hoist, two connecting plates with holes are installed on the hook, and the bolts are connected with the working cage and control the lifting of the cage. The staff stood in the cage to check and maintain the converter flue. However, this solution has the following problems:

1. The category of equipment is special, there are no domestic products, and no similar equipment can be found in the classification of special equipment, that is, the uncertainty of centralized management;

2. The equipment structure is complex, occupying a large space and self-heavy, correspondingly higher requirements for the plant structure, and the comprehensive investment cost is also high;

3. The safety of the equipment is relatively poor, mainly manifested in the fact that there is only one pair of steel wire ropes connected to the working cage (the hanging point of the cage is one point); when the steel wire rope is raised and lowered, the steel wire rope will generate relative friction with the flue structure at the corner of the flue, and the working The horizontal stability of the hanging cage is also poor, which poses a great threat to the safety of the staff.

Contents of the invention

The purpose of the utility model is to provide a pipeline overhaul device that can run vertically and in a turn, can run vertically and in a turn along the pipe wall, has a simple and reasonable structure, and is easy to operate.

In order to achieve the above purpose, the pipeline maintenance device of the utility model that can operate vertically and in a turn is placed in the maintenance pipeline; it includes a working platform, which is a hanging basket structure, connected by a bottom plate and several support frames; two The lifting mechanism is separately arranged on the support frame on both sides of the work platform, including the hoist, fixed on the support frame on the side of the work platform, and the upper traveling trolley through the wire rope; the upper limit plate, fixed on the work platform hanging basket support frame The upper part; the travel switch is set on the upper limit plate; the anti-tilt lock is fixed on the upper part of the support frame of the working platform hanging basket, and the safety wire rope passes through the anti-tilt lock; It includes hoisting device and motor, which are collected inside and connected to the hoist through steel wire ropes; at least two support wheels are respectively connected to the support frames on both sides of the work platform through a telescopic bracket; at least two guide wheels are respectively passed through a The telescopic support is connected to the supporting frames on the other two sides of the working platform.

In addition, casters are provided under the bottom plate of the working platform.

The corner of the flue is equipped with a supporting rod for the wire rope.

The beneficial effects of the utility model,

In the utility model, telescopic support wheels and guide wheels are installed on the support frames on both sides of the work platform, so that the work platform can be operated vertically and in a turn, and the work can be performed according to the shape of the pipeline.

Description of drawings

Fig. 2 is the side view of Fig. 1;

Fig. 3 is a schematic diagram of the use state of the utility model.

Detailed ways

Referring to Fig. 1 and Fig. 2, the pipeline maintenance device capable of vertical and turning operation of the present utility model is placed in the maintenance pipeline 9; it includes a working platform 1, which is a hanging basket structure, composed of a bottom plate 11 and several support frames 12 , 12' connected; two hoisting mechanisms 2, 2' are respectively located on the support frame 12, 12' on both sides of the work platform 1, including, respectively, the hoist 21, 21 ', which is fixed on the side of the work platform 1 The support frame 12, 12' is connected to the outside through the working wire rope 10; the upper limit plate 22, 22' is fixed on the upper end of the support frame 12, 12' on the side of the work platform; the travel switch 23, 23' is set on the upper limit On the bit plate 22, 22'; anti-tilt lock 24, 24', fixed on the support frame 12, 12' on the side of the work platform, and the safety wire rope 13, 13' passes through the anti-tilt lock 24, 24'; Two rope receiving mechanisms 3, 3' are respectively arranged on both sides of the work platform 1, respectively including hoisting devices 31, 31' and motors 32, 32', connected to the outside through a steel wire rope 10; two support wheels 4, 4', respectively Connect to the support frame 12, 12' on both sides of the work platform through a telescopic bracket 5, 5'; 2 guide wheels 6, 6' are respectively connected to the other two sides of the work platform through a telescopic bracket 7, 7' On the support frame 12, 12'; under the bottom plate 11 of the working platform 1, there are casters 8, 8'.

When the center of gravity composed of the maintenance personnel, the operating platform and the tools is within the plane range composed of the three points of the operating platform lifting point and the support wheel, the operating platform is always in a horizontal state, which ensures the horizontal stability of the operating platform. Within the plane range composed of points, the cage can only rotate in one direction around the axis formed by the lifting wire ropes on both sides of the work platform, which improves the stability of the cage accordingly; a power-off manual hoist is added (the operator and maintenance personnel are equipped with a life rope).

Referring to Fig. 3, when the working platform 1 reaches the corner of the flue 9, the steel wire rope 10 of the hanging basket will rely on the supporting rod 91 installed at the corner of the flue, so that the steel rope 10 does not directly contact the inner wall of the flue 9 (by the seamless steel pipe through which the cooling water passes). Composition) rub against each other. Working platform 1 is in the inclined section of flue 9, and adjusting the length of supporting wheels 4, 4' can make working platform 1 basically maintain horizontal state work at this position, and also guarantee the safety of maintenance personnel.
