Description

Technical Field

[0001] The utility model relates to the technical field of hoisting tools, in particular to a hoisting tool for a field bridge trolley guard plate. Background Art

[0002] A container crane (also known as a tire-type container gantry crane, abbreviated as RTG) is a special lifting machine in container terminals and container yards, and plays an important role in container sorting and handling. In a container crane, a container crane trolley is an important device for lifting and moving containers. A travel track is set above the container crane, and a travel wheel that matches the travel track is set on the container crane trolley, which can move linearly along the track on the container crane.

[0003] In order to prevent objects or workers around the track from being drawn into the traveling wheels during the travel of the field bridge trolley and causing damage to the equipment and workers, the existing technology requires the installation of a field bridge trolley wheel guard in front of the traveling wheel, and some also require the installation of a transverse guide wheel in front of the field bridge trolley wheel guard. The field bridge trolley wheel guard is generally a thick steel plate with multiple groups of rivet holes symmetrically arranged on the surface. During installation, the rivet holes of the field bridge trolley wheel guard are aligned with the rivet holes at the corresponding positions on the field bridge trolley, and fastening bolts are used to pass through the rivet holes on the field bridge trolley wheel guard and the field bridge trolley for fastening.

[0004] However, the installation and replacement of the wheel guard of the yard crane trolley requires the use of lifting belts to tie the wheel guard of the yard crane trolley and then use a crane to lift it to the yard crane trolley frame platform. Then, it is manually lifted and placed vertically in front of the yard crane trolley, and then the fastening bolts are installed. The weight of the yard crane trolley can reach more than 200kg. On the one hand, if the early bundling is not firm during the crane lifting process, there is a risk of falling objects from high altitude. On the other hand, there are safety hazards of squeezing and smashing injuries to the operators during the lifting process. In addition, due to the narrow space on the yard crane trolley frame platform, it is difficult to ensure the safety of the standing position when multiple people are operating. The difficulty and risk of high-altitude operations are relatively large. Utility Model Content

[0005] In view of the problems that the existing technology for installing and replacing the wheel guard plates of the yard bridge trolley has the risks of falling objects from high altitude and injuries to operators, and the high difficulty of high-altitude operations, the utility model provides a wheel guard plate lifting tool for the yard bridge trolley. The utility model can be used in conjunction with a lifting device to directly lift the wheel guard plate of the yard bridge trolley to the installation position, and it will not get loose and fall during the lifting process; during the installation of the wheel guard plate of the yard bridge trolley, the operators do not need to lift the wheel guard plate of the yard bridge trolley, the risk of injury to operators is small, and the difficulty of high-altitude operations is low, so the safety of operators can be ensured during the replacement of the yard bridge trolley.

[0006] The utility model provides a hoisting tool for a quay crane trolley wheel guard plate, which comprises a horizontally arranged first cross beam. A lifting lug is arranged on the top surface of the first cross beam. Two first longitudinal beams are vertically connected to the bottom of the first cross beam. The distance between the two first longitudinal beams is the same as the distance between two equal-height bolt holes on the quay crane trolley wheel guard plate.

[0007] A second cross beam is horizontally connected to the bottom of each first longitudinal beam. The two second cross beams are both skew perpendicular to the first cross beam.

[0008] Two second longitudinal beams are vertically connected to the bottom of each second cross beam. The distance between the two second longitudinal beams connected to the same second cross beam is greater than the thickness of the quay crane trolley wheel guard plate.

[0009] A frame connection hole is arranged at the bottom of each second longitudinal beam. Two frame connection holes on the two second longitudinal beams connected to the same second cross beam form a group. There are two groups, a total of four frame connection holes on the quay crane trolley wheel guard plate. The opening direction of each frame connection hole is parallel to the second cross beam.

[0010] The hoisting tool also includes two pin shafts for passing through the frame connection holes. The length of each pin shaft is greater than the sum of the distance between the two second longitudinal beams connected to the same second cross beam and the thickness of the two second longitudinal beams.

[0011] Further, the pin shaft is an external hexagon bolt, and the hoisting tool also includes a nut corresponding to the specification of the external hexagon bolt.

[0012] Further, a lifting lug is arranged on the top surface of the first cross beam. The lifting lug is arranged at the center of the top surface of the first cross beam, and the opening direction of the lifting lug is perpendicular to the first cross beam.

[0013] In another embodiment of the utility model, two lifting lugs are arranged on the top surface of the first cross beam. The two lifting lugs are symmetrically arranged on the top surface of the first cross beam. The opening directions of the two lifting lugs are both perpendicular to the first cross beam. The two lifting lugs can cooperate with multiple hoisting tools such as hooks or cables to prevent the hoisting tool for the quay crane trolley wheel guard plate from shaking or tilting during hoisting.

[0014] Further, a first slide rail is arranged on the first cross beam. The first longitudinal beam is slidably connected to the first slide rail. By arranging the first slide rail, a sliding connection can be realized between the first cross beam and the two first longitudinal beams, and the distance between the two first longitudinal beams can be adjusted by sliding.

[0015] Further, a second slide rail is arranged on each second cross beam. The second longitudinal beam is slidably connected to the second slide rail. By arranging the second slide rail, a sliding connection can be realized between each second cross beam and the two second longitudinal beams connected thereto, and the distance between the two second longitudinal beams connected to the same second cross beam can be adjusted by sliding.

[0016] Further, the primary cross beam, secondary cross beam, primary longitudinal beam, secondary longitudinal beam, and lifting lugs are all made of stainless steel.

[0017] The beneficial effects of the present utility model are as follows:

[0018] 1. For the lifting tool for the field bridge trolley wheel guard plate provided by the present utility model, a pin shaft can be used to pass through the frame connection hole and the bolt hole of the field bridge trolley wheel guard plate, so as to firmly install the field bridge trolley wheel guard plate on the lifting tool for the field bridge trolley wheel guard plate. Then, a hoisting tool such as a crane can be directly used to lift the field bridge trolley wheel guard plate to the installation position, without the need for complex bundling and packaging of the field bridge trolley wheel guard plate. During the hoisting process, the field bridge trolley wheel guard plate will not loosen and fall, reducing the risk of falling objects from height.

[0019] 2. During the process of using the present utility model in cooperation with a hoisting tool to lift the field bridge trolley wheel guard plate, the field bridge trolley wheel guard plate always remains vertical under the action of gravity and does not need to be adjusted in direction. After the field bridge trolley wheel guard plate is lifted to the installation position, fixing bolts can be directly installed in the unoccupied bolt holes, and then the pin shaft is removed and the lifting tool for the field bridge trolley wheel guard plate is lifted away. Finally, fixing bolts are installed in the remaining bolt holes. During the process, the operator only needs to install bolts and remove the pin shaft, without the need to lift and carry the field bridge trolley wheel guard plate, and without the need for multiple people to perform complex operations, reducing the risk of injury to the operator and the difficulty of working at height, and ensuring the safety of the operator during the installation or replacement of the field bridge trolley wheel guard plate.
