Description

Safety device for internal construction of chimney

Technical Field

The utility model relates to an inside construction safety device of chimney for trade chimney inside constructions such as thermal power plant, chemical industry, metallurgy belong to high altitude construction safety device technical field.

Background

In the process of chimney anticorrosion construction, a special annular hanging basket for the chimney is generally adopted as a construction platform for operation, and the construction platform can move up and down at any time. The constructors on the platform (gondola) must wear safety belts as overhead workers. According to the requirement of safety regulations, safety belts cannot be directly fixed on hanging basket equipment and must be independent of the hanging basket equipment, so that a plurality of safety ropes are generally placed independently from a chimney top opening and then connected with safety belts on construction personnel through safety catches, the safety ropes are generally nylon safety ropes, one ends of the safety ropes are fixed on the chimney top opening, the other ends of the safety ropes are placed to the bottom of a chimney from the chimney top opening along the inner wall of the chimney, and each construction personnel on a hanging basket construction platform is provided with a corresponding safety catch and a corresponding safety rope.

Usually, the operators on the platform (hanging basket) are about ten people, so a corresponding number of safety ropes are required to be placed to connect safety belts on the operators.

Meanwhile, a hanging basket hanging mechanism and a lifting mechanism of the annular hanging basket special for the chimney need to be provided with more than twenty hanging basket special steel wire ropes as a bearing steel wire rope and a safety steel wire rope, and at the moment, safety ropes required by operating personnel are added, so that more than twenty steel wire ropes and more than ten nylon safety ropes are hung in the inner space of the chimney simultaneously.

Under the condition, the nylon safety rope is easy to be wound with a steel wire rope for a hanging basket due to the characteristics of the nylon safety rope, so that the construction efficiency is influenced, and potential safety hazards are caused. Meanwhile, too many nylon safety ropes are arranged, so that the construction cost is increased.

Therefore, it is necessary to design a safety device as a substitute for the fixed end of the safety belt and the safety rope, which can meet the safety coefficient requirement of the construction operator inside the chimney, avoid the winding of the steel wire rope, reduce the construction cost and increase the construction efficiency.

Disclosure of Invention

The to-be-solved technical problem of the utility model is: the utility model provides a chimney internal construction safety device, as the substituting means of inside constructor's of chimney safety belt stiff end and polyamide fibre safety rope, can satisfy the bearing requirement completely when reducing the configuration quantity of safety rope, effectively avoid wire rope for the hanging flower basket and operating personnel to twine with the safety rope each other.

In order to solve the technical problem, the technical scheme of the utility model a chimney inside construction safety device is provided, a serial communication port, including four wire rope, all be equipped with one on every wire rope and prevent inclining the safety lock, be equipped with one on every prevents inclining the safety lock and can the chucking wire rope swing arm, be equipped with horizontal wire rope's mounting hole at every lower extreme that prevents inclining the safety lock, horizontal wire rope passes the mounting hole and connects a plurality of safety locks of preventing inclining fixedly.

Preferably, the diameter of the steel wire rope is 8.6 mm.

Preferably, the diameter of the transverse steel wire rope is 8.6 mm.

Preferably, the steel wire rope passes through the anti-tipping safety lock.

Preferably, the transverse steel wire rope penetrates through a mounting hole in the lower portion of the anti-tilting safety lock to connect the anti-tilting safety locks into a circle, and finally the anti-tilting safety locks are butted through U-shaped buckles to form a closed loop.

The utility model discloses a wire rope, horizontal wire rope, prevent inclining the safety lock, interconnect, form the safety device that the round can reciprocate, as the stiff end of construction operation personnel safety belt on the hanging flower basket.

The utility model provides an inside construction safety device of chimney has following beneficial effect:

1. the application range is wide: the method can be used for the corrosion prevention construction of various chimneys with different diameters;

2. the device is safe and reliable: the steel wire rope (breaking force) and the safety lock (allowable impact force) for the hanging basket equipment are far higher than the nylon safety rope equipped by construction operators, and the safety coefficient is greatly improved;

3. simple and practical: the composition mode is simple, and the installation and the disassembly are easy;

4. reduce safety rope and set up quantity: the safety belt fixing requirements of more than ten constructors can be met only by placing four longitudinal safety ropes (steel wire ropes), and the influence (easy winding) of the excessive safety ropes on the steel wire ropes of the hanging basket is avoided.

Detailed Description

In order to make the present invention more comprehensible, preferred embodiments are described in detail below with reference to the accompanying drawings.

As shown in fig. 1 to 2, a safety device for chimney internal construction is characterized by comprising four steel wire ropes 1, each steel wire rope 1 is provided with an anti-tilt safety lock 2, each anti-tilt safety lock 2 is provided with a swing arm 5 capable of clamping the steel wire rope 1, the lower end of each anti-tilt safety lock 2 is provided with a mounting hole 4 of a transverse steel wire rope 3, the transverse steel wire ropes 3 penetrate through the mounting holes 4 to connect and fix the anti-tilt safety locks 2, the diameter of each steel wire rope 1 is 8.6mm, the diameter of each transverse steel wire rope 3 is 8.6mm, each steel wire rope 1 penetrates through the corresponding anti-tilt safety lock 2, the transverse steel wire ropes 3 penetrate through the mounting holes 4 in the lower portion of the corresponding anti-tilt safety locks 2 to connect the anti-tilt safety locks 2 into a circle, and finally the anti-tilt safety locks 2 are butted through U-shaped buckles to form a closed loop.

When the steel wire rope type chimney is used, as shown in figure 1, four steel wire ropes 1 are placed at the top opening of the chimney, the steel wire ropes 1 can be special steel wire ropes which are common in the market and are used for chimney construction annular hanging baskets, the diameter of each steel wire rope is 8.6mm, and the breaking tension is more than 70 kn.

Inserting a steel wire rope 1 into an anti-tilt safety lock 2, wherein the anti-tilt safety lock 2 is basically characterized in that: under the condition that swing arm 5 is not atress, the locking piece locking is on wire rope 1, when the hanging flower basket reciprocated, constructor lifted swing arm 5 and just can loosen the locking piece, the utility model discloses a prevent inclining formula safety lock can adopt the special prevent inclining formula safety lock of common LSB30 type hanging flower basket on the market, and it allows the impact force to be 30 KN.

As shown in figure 2, a transverse steel wire rope 3 passes through a mounting hole 4 (originally used on a basket frame) at the lower part of the safety locks 2, the four safety locks 2 are connected into a circle, and finally, a U-shaped buckle (M10) is used for butt joint to form a closed loop.

During construction, an operator on the hanging basket construction platform buckles the hook of the safety belt on the transverse steel wire rope 3. In the process of vertical displacement of the hanging basket, a constructor lifts the swing arm 5 to loosen the locking block, and the transverse steel wire rope 3 and the safety lock 2 simultaneously move vertically. After the hanging basket stops moving up and down, the operator loosens his hands, the swing arm resets, and the safety lock is locked.
