Description

Technical Field

[0001] The invention relates to the technical field of driver's cabs, in particular to a crane driver's cab which is easy to clean. Background Art

[0002] The driver's cab is an important part of the lifting and transportation machinery to ensure the driver's safe operation. It is widely used in various lifting and transportation machinery such as container cranes, ship unloaders, tire port gantry cranes, floating cranes, shore container gantry cranes, ship loaders, metallurgical bridge cranes, general bridge cranes and tower cranes;

[0003] Crane cabs, such as the above-mentioned tire port gantry cranes, usually have skylights, which can supplement the internal light during the day and make it easier for the driver to observe the lifting situation in the cab. However, this type of skylight structure is usually not easy to clean, and dust accumulates, affecting the use effect. Summary of the invention

[0004] The object of the present invention is to provide a crane cab that is easy to clean, so as to solve the problems raised in the above background technology.

[0005] To achieve the above-mentioned purpose, the present invention provides the following technical solutions: a crane cab that is easy to clean, comprising a skylight structure arranged on the top of the cab, the skylight structure comprising a transmission gear for driving the skylight to slide, the transmission gear is driven by a motor, a slide rail is arranged below the transmission gear, the slide rail is an arc-shaped structure, the transmission gear is located at the center of the slide rail, a slider is slidably connected to the slide rail, a transition gear is rotatably installed on the slider, a dust-sticking rubber roller is installed on one side of the transition gear and the transmission transition gear, a passive gear is installed on the end of the slide rail away from the flexible window, the passive gear is rotatably connected to the inner wall of the cab, and a dust-sticking paper roll is connected to the passive gear;

[0006] When the transmission gear rotates forward, the transmission gear pushes the transition gear to slide along the slide rail to one side of the skylight structure, and the dust-sticking rubber roller on the transition gear contacts the skylight. When the transition gear reaches the end of the slide rail, it stops, and the transition gear only rotates on its own to achieve dust-sticking of the dust-sticking rubber roller to the flexible window.

[0007] When the transmission gear rotates in the opposite direction, the transmission gear pushes the transition gear and slides along the slide rail toward the passive gear until it meshes with the passive gear. The sticky rubber roller and the sticky paper roll rotate in relative contact, and the dust on the sticky rubber roller is transferred to the sticky paper roll.

[0008] Preferably, stop blocks are installed at both ends of the slide rail.

[0009] Preferably, two groups of sticky rubber rollers and sticky paper rolls are provided, which are arranged at both ends of the flexible window.

[0010] Preferably, the passive gear is located at a position avoiding a vertical projection range of the flexible window.

[0011] Preferably, a flexible window is embedded in the skylight structure, the flexible window is a rotary structure, and transmission rollers are installed at both ends of the inner side of the flexible window;

[0012] The outer side of the transmission roller is fixedly connected with the transmission gear.

[0013] Compared with the prior art, the invention has the following beneficial effects: the invention removes dust from the skylight by setting a dust-sticking rubber roller and a dust-sticking paper roll. Specifically, the dust from the skylight is stuck down by the dust-sticking rubber roller, and then the dust is transferred by the dust-sticking paper roll. When in use, only the paper roll needs to be replaced manually.

[0014] In addition, the present application sets up a combination structure of three gears, which is actually similar to the function of a one-way clutch. In the dust sticking stage, the dust sticking rubber roller is transferred to one side to contact the skylight, and then transferred to the side of the dust sticking paper roll after the dust sticking stage. This design can save space, and the dust sticking paper roll and the dust sticking rubber roller will not block the view of the skylight under normal conditions. At the same time, the dust sticking paper roll and the dust sticking rubber roller are basically at the top position and will not occupy the vertical space in the driver's cab.

[0018] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0019] like Figure 1-3 As shown, the present invention provides a technical solution: comprising a skylight structure arranged on the top of a driver's cab 1, the skylight structure comprising a transmission gear for driving the skylight to slide, the transmission gear 3 is driven by a motor, a flexible window 1 is embedded in the skylight structure, the flexible window 1 is a rotary structure, and transmission rollers are installed at both ends of the inner side of the flexible window 1;

[0020] The outer side of the transmission roller is fixedly connected to the transmission gear 3 .

[0021] A slide rail 2 is arranged below the transmission gear 3. The slide groove in the slide rail 2 is an arc-shaped structure. The transmission gear 3 is located at the center of the slide rail 2. A slider is slidably connected to the slide rail 2. A transition gear 5 is rotatably installed on the slider. The transition gear 5 and the transmission gear 3 form an effect similar to a planetary gear.

[0022] In order to improve the stability of operation, stop blocks are installed at both ends of the slide rail 2. In some preferred embodiments, the stop blocks can be designed as electromagnets, and the slider can be adsorbed by the electromagnets. When the transition gear 5 reaches both ends, it is adsorbed by the electromagnets.

[0023] A dust-sticking rubber roller 51 is installed on one side of the transition gear 5 and the transmission transition gear 5, and a passive gear 4 is installed on the end of the slide rail 2 away from the flexible window 1. The passive gear 4 is rotatably connected to the inner wall of the driver's cab 1, and a dust-sticking paper roll 41 is connected to the passive gear 4;

[0024] When the transmission gear 3 rotates forward, the transmission gear 3 pushes the transition gear 5 to slide along the slide rail 2 to one side of the skylight structure, and the dust-sticking rubber roller 51 on the transition gear 5 contacts the skylight. When the transition gear 5 reaches the end of the slide rail 2, it stops, and the transition gear 5 only rotates on its own to achieve dust-sticking of the skylight by the dust-sticking rubber roller 51.

[0025] When the transmission gear 3 rotates in the opposite direction, the transmission gear 3 pushes the transition gear 5 and slides along the slide rail 2 toward the passive gear 4 until it meshes with the passive gear 4. The sticky rubber roller 51 and the sticky paper roll 41 rotate in relative contact, and the dust on the sticky rubber roller is transferred to the sticky paper roll 41.

[0026] There are two groups of dust-sticking rubber rollers and dust-sticking paper rolls, which are arranged at both ends of the flexible window 1. Both ends of each group are provided with the above-mentioned gear structure.

[0027] The specific work includes dust sticking steps and transfer steps:

[0028] In the initial stage, the transition gear 5 is meshed with the passive gear 4, that is, the sticky rubber roller 51 and the sticky paper roll 41 are located on the same side, and the passive gear 4 is located away from the vertical projection range of the flexible window 1 and will not block the view of the skylight.

[0029] Reference Figure 3 As shown:

[0030] In the dust sticking step, the transmission gear 3 rotates in the forward direction (i.e., counterclockwise in the figure), the transition gear 5 arrives at the other end along the slide rail 2, and then rotates on its own, and the dust sticking rubber roller 51 contacts the flexible window to stick dust;

[0031] Transfer step, after the flexible window has completed dust collection, the transmission gear rotates in the opposite direction, the transition gear 5 returns to the initial position and meshes with the passive gear 4, and continues to rotate to transfer the dust to the sticky paper roll. Considering the amount of dust collection, the radius of the sticky paper roll can be larger. In addition, several gears can be meshed between the passive gear 4 and the transition gear 5, so that a larger space can be reserved between the passive gear 4 and the transition gear 5 to install a sticky paper roll with a larger radius. Moreover, the meshing gear between the two gears can adjust the speed of rotation of the sticky paper roll by designing the number of teeth. In actual applications, it is found that the sticky paper roll is faster than the sticky rubber roller and has a better effect, and can be designed according to the actual dust situation.

[0032] Although embodiments of the present invention have been shown and described, it will be appreciated by those skilled in the art that various changes, modifications, substitutions and variations may be made to the embodiments without departing from the principles and spirit of the present invention, and that the scope of the present invention is defined by the appended claims and their equivalents.
