Problems solved by technology
[0002] At present, the working condition of the boom of the crane is very heavy, and it often bears changing dynamic loads. The general boom shell structure is mainly composed of a U-shaped steel plate formed by cold pressing at the upper end and a load-bearing steel plate fixed at the bottom. The overall shell is in the shape of an I type, there is no other fixing structure, when the built-in parts need to be fixed, other special tools need to be used, which is time-consuming and labor-intensive

Embodiment Construction
[0011] Such as figure 1 It is a schematic diagram of the structure of the present invention. A boom shell of a crane includes a shell main body 1 and a load-bearing steel plate 2. The load-bearing steel plate 2 is fixed below the shell main body 1. The shell main body 1 is formed by welding two steel sheets 3. The steel sheet 3 There are arc-shaped openings at the upper end, and two pieces are combined together to form a card slot 4, and the outer ends of the concave arc surface in the middle of the steel sheet 3 are all provided with screw holes 5. The welding of the load-bearing steel plate and the steel sheet at the lower end solves the problem of arching of the crane arm. The plug-in bolt connection method is adopted, the installation is extremely simple, convenient and fast, no special tools are required for the installation work, and the four-point symmetrical connection has high safety performance. At the same time, the card slot on the top meets the needs of the suspe...

The invention relates to the technical field of crane suspension arms, in particular to a crane suspension arm shell. The suspension arm shell includes a shell main body and a load steel plate. The load steel plate is fixed below the shell main body. The shell main body is formed by welding two steel sheets, the upper ends of which are both equipped with an arc opening, and the two sheets can combine to form a blocking slot. The outer ends of recessed arc surfaces at the middle of the steel sheets are respectively provided with a fastening hole. The shell main body is an axisymmetric structural body. The width of two lateral sides of the load steel plate is greater than the width of an opening at the lower end of the shell main body. All parts of the suspension arm shell are sprayed with an anti-rust coating on surfaces. The crane suspension arm shell adopts a plug-in type bolt connection mode, and is extremely simple, convenient and rapid to mount. The mounting work has no need for any special tool. The shell is in four-point symmetric connection, and has very high safety performance. At the same time, the blocking slot at the top meets the suspension demands of plant buildings.
Description
technical field [0001] The invention relates to the technical field of crane booms, in particular to a crane boom casing. Background technique [0002] At present, the working condition of the boom of the crane is very heavy, and it often bears changing dynamic loads. The general boom shell structure is mainly composed of a U-shaped steel plate formed by cold pressing at the upper end and a load-bearing steel plate fixed at the bottom. The overall shell is in the shape of an I type, there is no other fixing structure, when the built-in parts need to be fixed, other special tools need to be used, which is time-consuming and labor-intensive. Contents of the invention [0003] In order to overcome the deficiencies of the prior art, the invention provides a boom shell of a crane. [0004] The technical solution adopted by the present invention to solve the technical problem is: a boom shell of a crane, including a shell main body and a load-bearing steel plate, the load-be...
