Description

Technical Field

[0001] The utility model belongs to the technical field of cranes, and in particular relates to a crane remote controller with dustproof effect. Background Art

[0002] As a large-scale handling equipment, a crane can move bundled materials by grabbing them in the horizontal and vertical directions. Gantry cranes, cranes and overhead cranes used in warehouses, docks and construction sites all belong to this category. A crane generally includes a crane frame, outriggers, a lifting trolley, a trolley traveling mechanism, a trolley traveling mechanism and a lifting mechanism. A remote control is required to operate the traveling motors on the trolley traveling mechanism and the trolley traveling mechanism, and a remote control is also required to operate the lifting mechanism. Therefore, the remote control is an important component of the crane. However, existing cranes are generally used outdoors and in dusty factory workshops. In the existing technology, the buttons on the crane remote control are exposed. During use, a lot of dust will adhere to the crane remote control over the years, blocking the gap between the remote control button and the remote control. Sometimes after pressing the remote control button, the dust blockage increases the friction, resulting in the button cannot be reset, causing the crane to keep pressing the remote control button instructions to move, and even causing safety accidents. Therefore, in order to prevent the crane remote control from dust, some staff members directly wrap the crane remote control with a plastic bag. Although the plastic bag has a certain dust-proof effect, it brings certain troubles to the staff in operating the remote control and may cause misoperation. Therefore, in the existing technology, the crane remote control has poor dust-proof effect and is still used. Utility Model Content

[0003] In order to solve the technical problem that the existing crane remote control has poor dust-proof effect and is inconvenient to use, the utility model provides a crane remote control with dust-proof effect, comprising a shell for placing the remote control body, the shell plays a protective role for the remote control body, the left end of the shell is detachably provided with a left cover plate, the left cover plate is fixed with an outlet pipe, the cables led out of the remote control body are led out from the outlet pipe, the right end of the shell is connected to a ventilation pipe, the ventilation pipe is provided with a filter element for filtering dust, and the right end of the ventilation pipe is detachably provided with a right cover plate, the right cover plate is provided with a plurality of ventilation holes, the left cover plate and the right cover plate both play a supporting and protective role, the top end of the shell is detachably fixed with an upper cover plate, the upper cover plate is provided with a key window, and the key window is provided with an elastic transparent plastic film, the transparent plastic film makes it easy to observe the key positions on the remote control body and at the same time makes it easy for staff to operate the keys on the remote control body.

[0004] Preferably, a vertically arranged connecting tube is provided at the left end of the upper cover plate, and a pressing airbag is also provided on the upper cover body. The pressing airbag is connected to the shell through the connecting tube. The setting of the pressing airbag facilitates the discharge of gas in the shell from the shell, which can reduce the temperature inside the shell.

[0005] Preferably, the filter element is made of filter cotton.

[0006] Preferably, the upper cover plate, the left cover plate and the right cover plate are all detachably fixed to the housing by fixing bolts.

[0007] Preferably, the shell, the left cover plate, the right cover plate and the upper cover plate are all made of soft PVC material.

[0008] The above solution has the following advantages:

[0009] The setting of the left cover, right cover and upper cover makes it easy to disassemble, replace or repair the remote control body inside the shell; the key window opened on the upper cover and the plastic film set in the key window make it easy for the staff to observe the keys on the remote control body through the window, and make it easy for the staff to accurately operate the keys on the remote control body; the setting of the ventilation pipe and the right cover can reduce the dust in the air from entering the shell; the setting of the press airbag makes it easy to discharge the gas in the shell from the shell, which can reduce the temperature inside the shell.

[0015] like Figure 1-4As shown, a dustproof crane remote control includes a housing 1 for housing the remote control body. The housing 1 protects the remote control body 6. A removable left cover 2 is attached to the left end of the housing 1. A cable outlet tube 21 is fixed to the left cover 2. Cables leading from the remote control body 6 are routed through the outlet tube 21. A vent 5 is connected to the right end of the housing 1. The vent 5 contains a filter element 51 for filtering dust. A removable right cover 3 is attached to the right end of the vent 5. The right cover 3 has several ventilation holes 31. Both the left and right covers 2 and 3 provide support and protection. A removable top cover 4 is attached to the top of the housing 1. A key window 41 is defined on the top cover 4. This key window 41 is covered with a resilient, transparent plastic film 42. This transparent plastic film 42 facilitates observation of the key positions on the remote control body 6 and facilitates operator control of the keys. A vertically arranged connecting tube 71 is provided at the left end of the upper cover plate 4, and a pressing airbag 7 is also provided on the upper cover body 4. The pressing airbag 7 is connected to the interior of the shell 1 through the connecting tube 71. The setting of the pressing airbag 7 facilitates the discharge of high-temperature gas in the shell 1 from the shell 1, which can reduce the temperature inside the shell 1.

[0016] Preferably, the filter element 51 is made of filter cotton.

[0017] Preferably, the upper cover plate 4 , the left cover plate 2 and the right cover plate 3 are all detachably fixed to the housing 1 by fixing bolts.

[0018] Preferably, the housing 1 , the left cover plate 2 , the right cover plate 3 and the upper cover plate 4 are all made of soft PVC material.

[0019] Usage process:

[0020] When the present invention is in use, first place the remote control body 6 in the shell 1, and then fix the left cover 2 and the upper cover 4 to the shell 1 respectively by fixing bolts, then place the filter element 51 on the vent pipe 5, fix the right cover 3 to the vent pipe 5 by fixing bolts, lead the cable on the remote control body 6 from the outlet pipe 21, and connect it to the crane control system. When the remote control body 6 generates a lot of heat in the shell 1, the staff presses the airbag 7 to discharge the gas in the shell 1 through the vent pipe 5, and the outside air enters the shell 1 through the vent hole 31 on the right cover 3. The filter element 51 filters out dust in the air to prevent dust from contaminating the remote control body 6. When the shell 1 needs to be cleaned, remove the left cover 2, the right cover 3 and the upper cover 4, and take out the remote control body 6.

[0021] In the description of the present invention, it should be understood that the terms "up", "down", "left", "right", "top", "bottom", "horizontal", "vertical", etc., indicating orientations or positional relationships, are based on the orientations or positional relationships shown in the accompanying drawings, and are only for the convenience of describing the present invention and simplifying the description, rather than indicating or implying that the device or element referred to must have a specific orientation, be constructed and operated in a specific orientation, and therefore cannot be understood as a limitation on the present invention.
