Background technique

The motor maintenance and installation process requires hoisting machinery. Electric or manual hoists are traditionally used hoisting machinery. However, due to the limitations of the motor specification and the environment in which it is located, scaffolding or small cranes are mainly used on site at present. Setting up scaffolding on site is time-consuming, labor-intensive, low-efficiency, and high-cost, so small cranes are the most commonly used hoisting machinery.

The Chinese utility model patent whose authorized announcement number is CN 201751366 U and whose authorized announcement date is 2011.02.23 discloses a small crane, which includes a frame (that is, a base), a column, an oil cylinder (that is, a hydraulic support rod), a crane The lower end of the column is fixed on the base, the upper end of the column is connected to the boom, the end of the boom far away from the column is provided with a hook, the lower end of the hydraulic support rod is hinged on the column, and the upper end is hinged on the on the boom. The base of the small crane is composed of two beams and two longitudinal beams. between the two longitudinal beams, and then lift the motor through the hook. Since the distance between the two longitudinal beams is fixed, this small crane can only be applied to a specific type of motor, and its scope of application is limited.

Utility model content

The purpose of the utility model is to provide a crane with a wide application range.

In order to achieve the above object, the technical solution of the utility model is:

A crane includes a base, the base includes a crossbeam and a longitudinal beam connected to the crossbeam, and an adjustment structure for adjusting the distance between the longitudinal beams is arranged on the longitudinal beam and/or the crossbeam.

The adjustment structure of the above-mentioned crane with the adjustment structure on the beam and/or the longitudinal beam is a socket provided on the longitudinal beam, and the beam and the longitudinal beam are connected by plug-in.

The above-mentioned cranes provided with adjustment structures on the beams and/or longitudinal beams are single beams or composite beams.

The above-mentioned crossbeam and longitudinal beam are a single beam or a crane of a composite beam. The crossbeam is a composite beam, including two parallel crossbars and a connecting beam connected between the two crossbars.

The above-mentioned crane with the adjustment structure or the adjustment structure is a socket provided on the longitudinal beam, and the beam and the longitudinal beam are plug-in connected. The crane also includes a column assembly fixed on the beam. The top of the column assembly is connected with a boom, and the boom The other end away from the column assembly is provided with a hook, and the crane provided with the column assembly also includes a hydraulic support rod with one end hinged to the column assembly and the other end hinged to the boom.

The above-mentioned crossbeam and longitudinal beam are single beams or composite beams and the crossbeams are composite beams, and the crane comprising two mutually parallel crossbars and a connecting beam connected between the two crossbars also includes a column fixed on the crossbeams Assemblies, the crane provided with the column assembly also includes a hydraulic support rod with one end hinged to the column assembly and the other end hinged to the boom.

The crane above also includes a column assembly fixed on the beam, and the column assembly is a lifting column.

The above-mentioned column assembly is a crane for lifting the column. The column assembly includes a sleeve and a movable column. One of the sleeve and the movable column is connected to the beam, and the other is connected to the boom. Both the sleeve and the movable column are provided with There are pin holes for adjusting the height of the movable column, and limit pins are inserted in the through holes.

The beneficial effect of the utility model is that: since the longitudinal beam and/or the cross beam is provided with an adjustment structure for adjusting the distance between the two longitudinal beams, the distance between the two longitudinal beams can be adjusted conveniently through the adjustment structure. In this way, when using the crane, the most suitable longitudinal beam spacing can be adjusted according to the size of the object to be hoisted, so that the object to be hoisted can be placed between the two longitudinal beams to complete the hoisting operation and increase the scope of application of the crane.

Further, when the beam and the longitudinal beam are composite beams, the strength of the base of the crane can be increased and the service life of the crane can be extended.

Further, the crane also includes a hydraulic support rod whose one end is hinged to the column assembly and the other end is hinged to the boom, which can help complete the swing of the boom and facilitate the lifting operation.

Further, the column of the crane is a movable column, and the most suitable boom height can be adjusted according to the model size of the object to be hoisted to ensure the completion of the hoisting operation.

Detailed ways

Embodiment 1 of the crane, as shown in Figure 1, includes a base, the base includes a crossbeam 5 and two longitudinal beams 7 connected to the crossbeam 5 at intervals, and the bottom of the longitudinal beam 7 is provided with universal wheels 6 for convenient hoisting. machine movement. The crossbeam 5 is a composite beam, including two parallel crossbars and a connecting beam connected between the two crossbars to increase the strength of the base, and the longitudinal beam 7 is provided with an adjustment structure for adjusting the distance between the two longitudinal beams , in this embodiment, the adjustment structure is a socket opened on the longitudinal beam 7, and the crossbeam 5 and the longitudinal beam 7 are plug-in connections. The crane also includes a column assembly fixed on one of the crossbars of the combined beam. The column assembly includes a sleeve 3 fixed on the beam and a movable column 2 sleeved in the sleeve. The sleeve 3 and the movable column 2 Each is provided with a pin hole 4 for adjusting the height of the movable column, and a limit pin 8 is inserted in the pin hole 4 . The top of the movable column 2 is hinged with a boom 1 to facilitate the folding of the crane. The other end of the boom 1 away from the movable column is provided with a hook 10. The crane also includes one end hinged with the movable column 2 and the other end hinged with the boom 1. The hydraulic support rod 9.

The working principle of the crane is: when the crane needs to be used for hoisting operations, according to the model size and installation width of the motor, adjust the longitudinal beam to slide on the beam through the socket, so that the distance between the two longitudinal beams can be adjusted conveniently. The spacing between them enables the motor to be placed between two longitudinal beams. Then adjust the height of the movable column in the sleeve according to the installation height of the motor, and fix its position in the pin hole with a limit pin. Then push the crane to the side of the motor, place the motor between the two longitudinal beams, control the boom to swing up and down through the hydraulic support rod, lift the motor, then exit the crane, remove the motor for maintenance, and put it back on again after repairing its installed on.

Embodiment 2 of the crane is shown in FIG. 2 . The difference between this embodiment and Embodiment 1 is that the upright column is a fixed upright column whose height cannot be adjusted.

Embodiment 3 of the crane is shown in FIG. 3 . The difference between this embodiment and Embodiment 1 is that the longitudinal girder is a composite girder formed by connecting multiple longitudinal rods.

Embodiment 4 of the crane is shown in Figure 4. The difference between this embodiment and Embodiment 1 is that the beam is a single beam.

Embodiment 5 of the crane is shown in Figure 5. The difference between this embodiment and Embodiment 1 is that the crossbeam is a telescopic beam, and the length of the crossbeam is adjusted by pin holes and stop pins, thereby adjusting the spacing of the longitudinal beams.

In other embodiments: the sleeve of the column assembly can also be fixed on the boom, and the movable column can be fixed on the beam; the column assembly can also be connected by bolts.
