Technical Field
[0001] The utility model relates to the technical field of guide mechanisms, in particular to a fork lifting guide mechanism for a loading platform. Background Art
[0002] In logistics, warehousing and other industries, forks are widely used. The forks need to be lifted when in use. Therefore, a lifting mechanism is provided on the forks. The existing forks are installed on guide rails. When the forks fork goods, the lifting of the forks needs to be controlled, and the lifting needs to be assisted by the guide mechanism during the lifting process. The guide mechanism has a complex structure, and is cumbersome to install and maintain. In addition, chain jumping is prone to occur during the displacement of the forks, resulting in the forks being displaced intermittently, which can easily cause the forks on the forks to topple over due to inertia, and the toppled goods themselves will be damaged, and in serious cases, workers will be injured. In addition, the transmission connection part of the forks is exposed, affecting the overall aesthetics of the forks. Utility Model Content
[0003] The technical problem to be solved by the utility model is: in order to solve the problem that the existing fork is installed on the guide rail, it is necessary to control the lifting of the fork when the fork forks the goods, and the lifting needs to be assisted by the guide mechanism during the lifting process. The guide mechanism has a complex structure, which is cumbersome to install and maintain, and the chain jumping phenomenon is likely to occur during the displacement of the fork, resulting in the fork displacement being intermittent, which can easily cause the fork on the fork to tip over due to inertia, and the tipped goods themselves will be damaged, and in serious cases, it will cause injuries to the staff, and the transmission connection part of the fork is exposed to the outside, affecting the overall aesthetics of the fork. A loading platform fork lifting guide mechanism is now provided.
[0004] The technical solution adopted by the utility model to solve its technical problems is: a loading platform fork lifting guide mechanism, the fork is arranged on a guide rail, the fork is provided with a lifting mechanism for lifting it on the guide rail, a chain conveying mechanism is arranged between the guide rail and the fork, the chain conveying mechanism is used to control the fork to move back and forth on the guide rail, the guiding mechanism is arranged between the chain conveying mechanism and the fork, the guiding mechanism comprises a guide slide plate and a connecting seat, the guide slide plate is arranged on the fork, a guide groove is opened on the guide slide plate, a guide wheel is rotated and installed on the connecting seat, the guide wheel matches the guide groove, the guide wheel is rollingly installed in the guide groove, the connecting seat is transmission-connected to the chain conveying mechanism, and a limiting mechanism for preventing the chain conveying mechanism from jumping the chain is arranged on the connecting seat. Compared with the prior art, in this solution, the connecting seat and the guide slide are matched through guide wheels and guide grooves to achieve sliding guidance of the connecting seat and the guide slide. The structure is simple, easy to install and maintain, and also reduces the cost of use. At the same time, the limiting mechanism is used to prevent the chain conveying mechanism from jumping the chain, thereby ensuring that the fork displacement is stable and reliable.
[0005] In order to ensure that the connection seat slides stably and reliably, in some preferred embodiments, guide slides are provided on both sides of the connection seat. By providing guide slides on both sides of the connection seat, both sides of the connection seat slide synchronously, ensuring that the connection seat slides stably and reliably.
[0006] Since the cooperation between the guide wheel and the guide groove will also affect the smooth operation of the fork when it is lifted, in some preferred embodiments, the guide wheel is a bearing. The guide wheel is set as a bearing, which has high precision and cooperates with the guide groove, so that the fork runs more smoothly when it is lifted, and the bearing can be directly purchased, which is convenient for maintenance.
[0007] Since there are two, three or more forks, and the forks are arranged in parallel, in order to ensure that the lifting heights of the forks are consistent and there is no inconsistency in the lifting heights of the forks, some embodiments preferably further include a mounting frame, the forks are fixedly mounted on the mounting frame, and the guide slide is fixedly mounted on the mounting frame.

By installing the baffle on the mounting frame, and the baffle is located between two adjacent forks, the components below the mounting frame are shielded, which, on the one hand, ensures that the components inside the mounting frame are not exposed, which plays a role in aesthetics, and on the other hand, plays a role in safety protection for the components inside the mounting frame.
[0009] In order to ensure that the displacement of the fork on the guide rail is stable and reliable, in some preferred embodiments, a first wheel is installed on the mounting frame, and the first wheel is used to support the mounting frame and the upper surface of the guide rail. By installing the first wheel on the mounting frame, the first wheel is located on the upper surface of the fork, and the first wheel ensures that the displacement of the fork on the guide rail is stable and reliable, and avoids the phenomenon of collision between the mounting frame and the upper surface of the guide rail when the fork is cheap.
[0010] In order to ensure that the displacement of the fork on the guide rail is stable and reliable, in some preferred embodiments, a second wheel is installed on the mounting frame, and the second wheel is used to support the mounting frame and the side of the guide rail. By installing the second wheel on the mounting frame, the second wheel is located on the side of the fork, and the second wheel ensures that the displacement of the fork on the guide rail is stable and reliable, and avoids the phenomenon of collision between the mounting frame and the side of the guide rail when the fork is cheap.
[0011] In some preferred embodiments, both the first wheel and the second wheel are bearings.
[0012] In order to realize the limiting mechanism, some embodiments are preferred, wherein the limiting mechanism includes a limiting groove opened on the connecting seat, the limiting groove is arranged axially along the chain conveying mechanism, the limiting groove is used to limit the chain conveying mechanism, and the connecting seat is provided with a pin fixedly connected to the chain conveying mechanism, and the pin passes through the limiting groove.
[0013] The beneficial effects of the utility model are as follows: when the loading platform fork lifting guide mechanism of the utility model is in use, the connecting seat and the guide slide plate are matched through the guide wheel and the guide groove to realize the sliding guidance of the connecting seat and the guide slide plate. The structure is simple, easy to install and maintain, and the use cost is also reduced. At the same time, the limit mechanism is used to prevent the chain conveying mechanism from jumping the chain, thereby ensuring the stable and reliable displacement of the fork, avoiding the problem that the existing fork is installed on the guide rail, and when the fork forks the goods, it is necessary to control the lifting of the fork, and the guiding mechanism needs to be used for auxiliary lifting during the lifting process. The guiding mechanism has a complex structure, which is cumbersome to install and maintain, and the chain jumping phenomenon is likely to occur during the displacement of the fork, resulting in the fork moving intermittently, which can easily cause the fork on the fork to tip over due to inertia, and the tipped goods themselves will be damaged, and in serious cases, it will cause injuries to the staff, and the transmission connection part of the fork is exposed to the outside, affecting the overall aesthetics of the fork.
