Description

Technical Field

[0001] This patent relates to the field of engineering installation technology, and specifically to a special tool for mounting, lifting and placing a main engine. Background Art

[0002] During construction, the hoisting and installation of mainframes is one of the most critical tasks in the mid-term of a project. Each time, one mounting frame (2 tons) must be completed, meaning 20 mainframes must be hoisted. These high-value and heavy mainframes are difficult to hoist and install. In practice, the on-site construction environment is cramped and lacks space. Common hoists are incompatible with the on-site construction environment, posing safety risks and making it difficult to complete the hoisting and installation of the mainframes smoothly and quickly.

[0003] The existing installation technology has many shortcomings in actual operation, such as:

[0004] (1) The construction location is narrow and the general sling is too long, which does not meet the space requirements;

[0005] (2) The general spreader needs to be tilted when entering, which may cause safety accidents;

[0006] (3) General lifting equipment cannot maintain balance during lifting, and is prone to shaking in the air, damaging the main machine, and is prone to deformation, causing greater damage. Summary of the Invention

[0007] The purpose of the present invention is to provide a special tool for hoisting and placing the main machine in order to address the shortcomings of the original method in the prior art, which can effectively, quickly and safely hoist and place the main machine, is easy to enter and exit, does not require tilting the hoist, maintains stable hoisting, simplifies the work process and improves work efficiency.

[0008] The technical solution of the present invention is as follows: a special tool for mounting and lifting a main machine, comprising an I-shaped frame body, with a lifting lug fixed in the middle of a rectangular frame body; the I-shaped frame body is provided with a lifting lug, the lifting lug is connected to a steel wire rope, and the steel wire rope is connected to a special hook.

[0009] The rectangular frame body is provided with a permanent magnetic iron sheet.

[0010] There is a permanent magnetic iron sheet at each end of the rectangular frame body.

[0011] The material of the special tooling for mounting, lifting and placing the main engine is carbon steel.

[0012] The special tooling for mounting, lifting and placing the main machine is 2300mm long and 1080mm wide.

[0013] There is a lifting lug at each corner of the I-shaped frame body, each lifting lug is connected to a steel wire rope, and each steel wire rope is connected to a special hook.

[0014] During operation, a special hook is connected to the corresponding hole on the main frame, the main frame is lifted and moved horizontally to above the landing position. The main frame falls to the specified position, and the construction personnel take out the special hook 4 to fix the main frame.

[0015] The remarkable effects of the present invention are:

[0016] (1) The special tooling for hoisting and placing a host described in this patent can lift and place a host frame, making it easy to lift and place, and providing sufficient space for hoisting and placing;

[0017] (2) The special tooling for hoisting and placing the main engine described in this patent does not require any additional method to be placed in the door-shaped frame, which greatly reduces safety risks;

[0018] (3) The special tooling for hoisting and placing the main engine described in this patent is easy to operate. It only needs to be adjusted and then hoisted to the main engine frame. During the hoisting and placement, the frame is stable and the tooling structure is solid, which greatly improves work efficiency. BRIEF DESCRIPTION OF THE DRAWINGS

[0024] The following description sets forth many specific details to facilitate a thorough understanding of the present application. However, the present application can be implemented in many other ways than those described herein, and those skilled in the art can make similar generalizations without violating the scope of the present application. Therefore, the present application is not limited to the specific implementations disclosed below.

The singular forms "a", "the" and "the" used in one or more embodiments of the present application and the appended claims are also intended to include plural forms, unless the context clearly indicates otherwise. It should also be understood that the term "and / or" used in one or more embodiments of the present application refers to and includes any or all possible combinations of one or more associated listed items.

[0026] It should be understood that although the terms "first," "second," and the like may be used to describe various information in one or more embodiments of the present application, such information should not be limited to these terms. These terms are merely used to distinguish information of the same type from one another. For example, "first" may also be referred to as "second," and similarly, "second" may also be referred to as "first," without departing from the scope of one or more embodiments of the present application.

[0027] Special tooling for mounting and lifting the host, such as Figure 1 As shown, the I-shaped frame body (1) as the overall frame of the tooling is specially calculated to be slightly wider than the width of a mounting frame. A lifting lug (2) is fixed in the middle of the rectangular frame body (1) for use in crane lifting. Two permanent magnetic iron sheets (5) are fixed at both ends of the middle of the I-shaped frame body (1) for placing the steel wire rope so that it will not shake at will and damage the main machine. After calculation, four lifting lugs (6) are fixed below the four corners of the I-shaped frame body (1). Each of the four lifting lugs (6) is connected to a steel wire rope (3). The steel wire rope is connected to a special hook (4) to form the main body of the tooling for lifting and placing the main machine.

[0028] like Figure 2-4 The following are three views of the special tooling for hoisting and placing the main engine.

[0029] How to use

[0030] Transport the special tooling for the mainframe installation and hoisting to the designated location and stop;

[0031] The construction personnel lower the mainframe mounting frame and place the special tooling in place, and connect the special hooks (4) with the corresponding four holes on the mainframe mounting frame;

[0032] After the mainframe mounting frame and the special tooling for lifting and placing the mainframe are connected, the crane operator raises the crane and the mainframe mounting frame is lifted;

[0033] After the mainframe is hoisted to a certain height, it is moved horizontally to above the landing position, and the crane operator begins to land;
