Description

Technical Field

[0001] The utility model relates to the technical field of lifting equipment, in particular to a cab applied to lifting equipment and a lifting equipment. Background Art

[0002] In the field of modern construction machinery, especially in outdoor working environments, operators often have to face harsh weather conditions. Among them, strong light caused by direct sunlight and reflection is one of the common challenges. Working in such an environment not only damages the operator's vision, affects normal operation, and poses safety hazards, but also long-term exposure to sunlight may cause damage to the eyes and skin by ultraviolet rays, thereby triggering a series of health problems. In addition, in hot weather, a large amount of heat will accumulate in the cab, resulting in heat accumulation in the cab, which affects the operating comfort of the driver. The driver will face greater operating pressure. Even if the power of the air conditioning system is increased, it cannot solve the thermal effect of direct sunlight on the skin.

[0003] To solve the above problems, a sunshade is generally installed in the cab to block light. However, as a mechanical component, the sunshade needs to be manually pulled and closed every time it is used for shading. The operation is cumbersome, and it is easy to fall off, be damaged or jam due to long-term sliding, resulting in incomplete shading. In addition, the sunshade can only block light but has no heat insulation effect, and has limited effect on solving the problem of heat accumulation in the cab. Therefore, in related technologies, sometimes the glass window of the cab is set as dimming glass to solve the problems of glare and heat accumulation in the cab by changing the transparency of the glass.

[0004] Generally speaking, the dimming glass on the cab is in a dark state when it is not powered on, and the light transmittance is the lowest at this time. As the voltage gradually increases, the light transmittance of the dimming glass gradually increases. That is to say, the dimming glass usually relies on electricity to adjust the transparency. If the equipment encounters a power system failure, the dimming glass may not be able to maintain its required transparent state, resulting in limited vision of the driver and inability to observe the external construction environment in time, posing a safety hazard. Summary of the Utility Model

Detailed implementation manners

[0030] To make the objectives, technical solutions and advantages of the present invention clearer, the technical solutions in the present invention will be clearly and completely described below with reference to the accompanying drawings in the present invention. Obviously, the described embodiments are some, but not all, of the embodiments of the present invention. All other embodiments obtained by those of ordinary skill in the art based on the embodiments in the present invention without creative efforts shall fall within the protection scope of the present invention.

[0031] To facilitate the understanding of the cab and lifting equipment to which the present invention is applied, its application background will be introduced first. The strong light brought by direct sunlight and reflection is one of the harsh environments that drivers often face. The strong light will not only damage the operator's vision and affect normal operation, but also cause a series of health problems. In addition, the strong light will also cause heat accumulation in the cockpit and affect the comfort of the driver's operation. Even if the power of the air conditioning system is increased, it cannot solve the heat impact of direct sunlight on the skin.

[0032] To solve the above problems, a sunshade is generally installed in the cockpit to block light. However, each time the sunshade is used to block light, it needs to be manually pulled and closed, which is cumbersome to operate. In addition, it is easy to fall off, be damaged or jam due to long-term sliding, resulting in incomplete shielding. Moreover, the sunshade can only block light and has no heat insulation effect, and has limited effect on solving the problem of heat accumulation in the cockpit. Therefore, in related technologies, sometimes the glass window of the cockpit is set as a dimming glass to solve the problems of glare and heat accumulation in the cockpit by changing the transparency of the glass.

[0033] Generally speaking, the dimming glass on the lifting equipment is in a dark state when it is not powered on. At this time, the light transmittance is the lowest. As the voltage gradually increases, the light transmittance of the dimming glass gradually increases. That is to say, the dimming glass usually relies on electricity to adjust its transparency. If the equipment encounters a power system failure, the dimming glass may not be able to maintain the required transparent state, resulting in limited vision for the driver and inability to observe the external construction environment in a timely manner, posing a safety hazard.

[0034] In view of the above problems, the present utility model provides a cab and a lifting equipment applied to the lifting equipment, which can effectively solve the problems of strong light stimulation and heat accumulation in the cab, and enable the driver to observe the external environment in a timely manner when the lifting equipment fails, reducing the safety hazard.

[0035] The following combines Figures 1 - 7 to describe the cab and the lifting equipment applied to the lifting equipment of the present utility model.

[0036] Referring to Figure 1 , a cab applied to a lifting equipment includes a cab body 10 and a first glass and a second glass connected to the cab body 10; wherein, the first glass is connected to the front end of the cab, and the second glass is connected to the side, top and / or rear of the cab, and the second glass is set as a dimming glass; the first glass includes a dimming area 110 located above and a non-dimming area 111 located below, the dimming area 110 is set as a dimming glass, the non-dimming area 111 is set as a non-dimming glass, and an insulating film is covered on the non-dimming glass.

[0037] In a specific application scenario, when working outdoors, the light transmittance of the dimming glass can be adjusted according to the light intensity. When the external strong light shines, by lowering the light transmittance of the dimming area 110 of the first glass, the influence of the strong light on the driver's vision can be reduced, ensuring safe operation; the non-dimming area 111 of the first glass is covered with an insulating film, which can reflect, absorb or block infrared and ultraviolet rays in the strong light, and at the same time lower the light transmittance of the second glass, which can reduce the problem of heat accumulation in the cab caused by strong light irradiation, and effectively solve the heat influence of direct sunlight on the skin, improving the comfort of the driver's operation. When the lifting equipment encounters a power system failure, the dimming area 110 of the first glass and the second glass will turn into a dark state due to power interruption, and the driver can observe the environment outside the cab from the non-dimming area 111 of the first glass, reducing the safety hazard.

[0038] In an embodiment of the present utility model, in order to facilitate the adjustment of light transmittance, the dimming glass adopts electro-controlled dimming glass. According to different working principles, electro-controlled dimming glass is roughly divided into several types, including electrochromic (EC), suspended particle device (SPD), and polymer dispersed liquid crystal (PDLC), etc. Both EC glass and SPD glass can achieve continuous adjustment of transparency, that is, continuous dimming from completely transparent to basically opaque (even when the light transmittance of EC / SPD glass is 1%, it is still in a transparent state, but just darker), while PDLC glass cannot achieve the adjustment of transparency and can only achieve the switching between transparent and opaque. Therefore, the dimming glass can adopt EC glass or SPD glass.

[0039] EC glass generally includes two layers of solid thin-film conductive layers as electrodes, one layer of solid ion storage layer for ion access, one layer of solid / liquid ion electrolyte layer as an ion conduction channel, one layer of solid / liquid electrochromic layer for color change reaction, and two layers of laminated glass. When powered on, the ions in the electrochromic layer come to the ion storage layer through the conduction channel to undergo redox reactions, and the color of the electrochromic layer or the ion storage layer changes. By controlling the voltage, the amount of ions entering can be controlled to achieve stepless change of light brightness. However, considering cost and manufacturing difficulty, existing EC films can be attached to the glass to replace EC glass to achieve the electrochromic function of the dimming glass.

[0040] SPD glass is composed of two layers of solid conductive materials as electrodes, one layer of solid thin-film particle storage, and two layers of laminated glass, with suspended particles coated on the particle storage layer. When powered off, the particles are randomly arranged in Brownian motion, and more than 99% of the light is absorbed, and it is in a dark state at this time. After power on, the arrangement of the suspended particles becomes a straight line, and the light can pass through. By controlling the voltage magnitude, the number of particle arrangements can be controlled to achieve stepless change of light brightness. Similarly, considering cost and manufacturing difficulty, existing SPD films can be attached to the glass to replace SPD glass to achieve the electrochromic function of the dimming glass.

[0041] The working parameters of the dimming glass, such as the minimum light transmittance, maximum light transmittance, maximum ultraviolet transmittance, minimum shading coefficient, working temperature, energy consumption, response time, etc., can be selected and configured according to actual needs. In this embodiment, the minimum light transmittance of the dimming glass is below 1%, the maximum light transmittance is above 50%, the maximum ultraviolet transmittance is above 99%, the minimum shading coefficient is below 0.2, the operating temperature is -20°C to 80°C, the energy consumption is below 3 W / m2, and the response speed. The response time from dark to bright is at most within 10 s, and the response time from bright to dark is at most within 30 s.

[0042] In addition, the PDLC's property of being able to switch between transparent and opaque can be utilized and combined with EC or SPD to adjust the transparency while also enabling switching between transparent and opaque, thus achieving the privacy isolation effect during downtime for rest.

[0043] Specifically, the EC glass or EC film constitutes the EC layer of the electrochromic glass, the SPD glass or SPD film constitutes the SPD layer of the electrochromic glass, and the PDLC glass or PDLC film constitutes the PDLC layer of the electrochromic glass. By combining and overlapping the PDLC layer with the EC layer or SPD layer, stepless adjustment of transparency and switching between transparent and opaque can be achieved simultaneously, enabling the dimming glass to not only block strong light and provide heat insulation but also offer privacy isolation during downtime for rest.

[0044] It should be noted here that the PDLC layer and the EC layer or SPD layer are separate functional layers, and the operation between different functional layers does not interfere with each other, thus enabling joint control between the PDLC layer and the EC layer or SPD layer.

[0045] The dimming glass can adopt the EC glass, SPD glass, PDLC + EC glass, or PDLC + SPD glass provided in the above embodiments.

[0046] In an embodiment of the present utility model, referring to Figure 3 , the first glass is connected to the front end of the cab body 10 to form the front windshield 11. The main function of the dimming area 110 is to block the sunlight directly shining from the front and avoid strong light from damaging the driver's vision. Parameters such as the position and area of the dimming area 110 can be configured according to actual needs, as long as its area meets the basic blocking requirements, that is, when the solar altitude angle is at least 30°, the operator's height is at least 160 mm, the seat is at the frontmost position of the track, and the seat is not in the reclined state (seat angle 100°), it can block the driver's face to prevent sunlight from dazzling.

[0047] The main function of the non-dimming area 111 is to facilitate the driver to obtain the view outside the vehicle when the power system of the lifting equipment fails. Specifically, the non-dimming glass in the non-dimming area 111 can adopt common laminated glass. The heat insulation film covered on the non-dimming glass can reflect, absorb, or block infrared and ultraviolet rays in strong light, achieving a heat insulation effect and effectively avoiding the heat impact brought by strong light incident on the cab through the non-dimming area 111. The heat insulation film can specifically adopt LOW-E coating or a metallized film such as silver coating.

[0048] In an embodiment of the present utility model, referring to Figures 1 to 4, the second glass includes side window glasses disposed on both sides of the cab body 10. According to different positions, the side window glasses are specifically divided into a left window glass 12 and a right window glass 13. For a lifting device, a door is generally provided on the left side of the cab. Therefore, the left window glass 12 can be further divided into a first left window glass 120 connected to the door and a second left window glass 121 not connected to the door. Of course, the arrangement of the side window glasses is not limited to the forms listed above, and side window glasses arranged in other forms are equally applicable.

[0049] Among them, at least one side window glass is provided with a louver 14. Through the louver 14, the driver can communicate with the outside inside the cab, improving the connectivity between the inside and the outside of the cab. When the power system of the lifting device fails, the driver can also obtain the side view of the lifting device through the louver 14, which is beneficial for the driver to more comprehensively know the environment outside the vehicle.

[0050] In an embodiment of the present utility model, the second glass further includes a top window glass 15 connected to the top of the cab body 10 and a rear window glass 16 connected to the rear end of the cab body 10, which is beneficial to improve the brightness inside the cab and the driver's field of view.

[0051] For the convenience of control, the cab further includes a controller. The controller is electrically connected to the dimming glass and is used to adjust the light transmittance of the dimming glass as a whole, individually, in groups or in sub-regions according to adjustment instructions. Specifically, the controller can be an electronic control unit (ECU) of the lifting device.

[0052] The above-mentioned overall adjustment refers to the overall regulation of all the dimming glasses on the cab.

[0053] The above-mentioned individual adjustment refers to individually adjusting the light transmittance of the front window glass, the first left window glass 120, the second left window glass 121, the right window glass 13, the top window glass 15 and the rear window glass 16 of the cab. In this way, it is beneficial to flexibly adjust the light transmittance of the dimming glasses at different positions according to different environments.

[0054] The above-mentioned group adjustment refers to that the dimming glasses at different positions can be grouped and controlled. For example, the left window + the right window, the left window + the rear window, the left window + the front window, the left window + the top window, two pieces of glass are in a group, or three pieces, four pieces of glass are in a group, and each group of glasses is regulated simultaneously during adjustment.

[0055] The above-mentioned sub-region control refers to that the same dimming glass can be divided into different regions, and different regions are individually regulated during adjustment.

[0056] The above control methods can be selected alternatively, or different control methods can be combined, and can be flexibly configured according to actual requirements. In this embodiment, the method of individually controlling each piece of dimming glass + overall controlling all dimming glasses is adopted.

[0057] In some alternative embodiments, there are multiple triggering methods for the control instructions, such as mechanical control keys 17, touch screen control keys 18, touch films 19, and sensors.

[0058] In an embodiment of the present invention, referring to Figures 4 to 7 , the cab further includes a mechanical control key 17 for triggering an adjustment instruction. The mechanical control key 17 is communicatively connected to the controller. The mechanical control key 17 can trigger an adjustment instruction, and the controller adjusts the light transmittance of the dimming glass according to the adjustment instruction.

[0059] Specifically, referring to Figure 5 , the mechanical control key 17 can adopt a rotary control key, which includes multiple knobs or buttons corresponding to the number of dimming glasses. As shown in the figure, the mechanical control key 17 includes seven knobs 7a, 7b, 7c, 7d, 7e, 7f, and 7g and one button 7h. Among them, 7a is used to adjust the transparency of the front window glass dimming area 110, 7b is used to adjust the transparency of the rear window glass 16, 7c is used to adjust the transparency of the top window glass 15, 7d is used to adjust the transparency of the right window glass 13, 7e is used to adjust the transparency of the first left window glass 120, 7f is used to adjust the transparency of the second left window glass 121, 7g is used to adjust the transparency of all dimming glasses simultaneously, and 7h is used to control the opening and closing of the voltage of all the dimming glasses in the vehicle.

[0060] Specifically, the above knobs can adopt encoder-type knobs with infinite rotation, which can realize stepless adjustment of the dimming glass.

[0061] In another embodiment of the present invention, the cab further includes a touch screen control key 18 for triggering an adjustment instruction. The touch screen control key 18 can adopt a slide bar or a touch key.

[0062] In a specific embodiment, referring to Figure 6 , the touch screen control key 18 includes eight slide bars 8a, 8b, 8c, 8d, 8e, 8f, and 8g. Among them, 8a is used to adjust the transparency of the front window glass dimming area 110, 8b is used to adjust the transparency of the rear window glass 16, 8c is used to adjust the transparency of the top window glass 15, 8d is used to adjust the transparency of the right window glass 13, 8e is used to adjust the transparency of the first left window glass 120, 8f is used to adjust the transparency of the second left window glass 121, and 8g is used to adjust the transparency of all dimming glasses simultaneously. By sliding different slide bars along a predetermined direction, stepless adjustment of the light transmittance of the corresponding dimming glass is realized.

[0063] In another embodiment of the present utility model, referring to Figure 7 , a touch film 19 is added to each piece of dimming glass. The touch film 19 can sense the pressure on the glass surface and the sliding direction. When the driver swipes upward, the touch film 19 senses the pressure command and transmits the signal to the controller, and the controller controls the voltage of the dimming glass to adjust the transparency of the dimming glass.

[0064] In another embodiment of the present utility model, the regulation command can also be triggered by a sensor.

[0065] In a specific embodiment, the sensor includes a facial light and shadow sensor 20; the facial light and shadow sensor 20 is communicatively connected to the controller and is used for collecting the light distribution on the driver's face, and the controller adjusts the light transmittance of the dimming glass at different positions according to the light distribution on the driver's face.

[0066] Specifically, the specific type, structure and working principle of the facial light and shadow sensor 20 can refer to the prior art and will not be elaborated in the embodiments of the present utility model. The facial light and shadow sensor 20 can be installed above the front end of the cab for collecting the light distribution on the driver's face. When the light on one side of the driver is stronger, the controller adjusts the light transmittance of the dimming glass at the corresponding position, thereby avoiding the influence of strong light on the driver.

[0067] In another specific embodiment, the sensor includes a light recognition sensor; the light recognition sensor is communicatively connected to the controller and is used for collecting the light intensity, and the controller adjusts the light transmittance of the dimming glass according to the light intensity.

[0068] Specifically, the specific type, structure and working principle of the light recognition sensor can refer to the prior art and will not be elaborated in the embodiments of the present utility model. The light recognition sensor can be installed outside the cab and above the front end of the cab for collecting the light intensity at an instantaneous moment, and combined with the controller, it automatically controls the sensitivity of the glass. The influencing factors of the light intensity include the change of the solar altitude angle, the change of the cloud cover amount, the change of the weather, the change of the cab position, etc.

[0069] In another embodiment of the present utility model, the sensor includes a vision / voice recognition sensor; the vision / voice recognition sensor is communicatively connected to the controller and is used for collecting the actions / voices of the driver, and the controller adjusts the light transmittance of the dimming glass according to the actions / voices of the driver.

[0070] Specifically, for the specific types, structures, and working principles of the vision / voice recognition sensors, reference can be made to the prior art, and no detailed description will be given in the embodiments of the present utility model. Among them, the vision recognition sensor can capture the driver's actions such as gestures, and the controller adjusts the light transmittance of the dimming glass according to the driver's actions; while the voice recognition sensor can recognize the driver's voice, and the controller adjusts the light transmittance of the dimming glass according to the voice commands issued by the driver.

[0071] It can be understood that the above-mentioned ways for triggering the adjustment command can be selected alternatively, or different ways can be combined and used, and specifically, it can be selected according to actual needs.

[0072] In an embodiment of the present utility model, an HUD (Optical Head-Up Display) projection area can also be provided on the front window glass. The HUD projection area is used to display the images projected by the HUD projection device, providing navigation instructions, vehicle speed, and other driving-related information for the driver.

[0073] It should be noted that for the specific structure and working principle of the HUD, reference can be made to the prior art, and no detailed description will be given in the embodiments of the present utility model.

[0074] It can be understood that, without contradiction, those skilled in the art can combine and combine the different embodiments or examples described in this specification and the features of different embodiments or examples.

[0075] The hoisting equipment provided by the present utility model will be described below. The hoisting equipment described below can be correspondingly referred to the cab applied to the hoisting equipment described above.

[0076] A hoisting equipment includes the cab applied to the hoisting equipment provided in any of the above embodiments.

[0077] The hoisting equipment includes, but is not limited to, mobile or non-mobile cranes such as wheeled cranes, tower cranes, and ring rail cranes.

[0078] With the cab for a lifting device and the lifting device provided by the present utility model, during outdoor operations, the light transmittance of the dimming glass can be adjusted according to the light intensity. When the outside is irradiated by strong light, by reducing the light transmittance of the first glass dimming area 110, the influence of the strong light on the driver's vision can be reduced, ensuring safe operations. The non-dimming area 111 of the first glass is covered with a heat-insulating film, which can reflect, absorb or block infrared and ultraviolet rays in the strong light. At the same time, reducing the light transmittance of the second glass can reduce the problem of heat accumulation in the cab caused by strong light irradiation, and effectively solve the thermal influence of direct sunlight on the skin, improving the comfort of the driver's operation. When the lifting device encounters a power system failure, the dimming area 110 of the first glass and the second glass will turn dark due to power interruption, and the driver can observe the environment outside the cab from the non-dimming area 111 of the first glass, reducing potential safety hazards.

[0079] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of the present utility model and are not intended to limit them. Although the present utility model has been described in detail with reference to the foregoing embodiments, those of ordinary skill in the art should understand that they can still modify the technical solutions described in the foregoing embodiments or perform equivalent replacements for some of the technical features.
