Technical Field

[0001] The utility model relates to the technical field of excavator driving cab frames, in particular to a cab frame structure for a mini-excavator. Background Art

[0002] With the development of the economic society, mini-excavators have been increasingly applied to small construction projects. To adapt to more working conditions and meet the environment with a low working height, it is required that the driving cab frame on the mini-excavator can be quickly disassembled and assembled.

[0003] The existing mini-excavator with a driving cab frame will make the overall height of the whole machine relatively high, and it is necessary to reduce the height to carry out operations. The traditional method is to remove the driving cab. However, the driving cab is integral. Once it is removed, there will only be a control device on the upper part of the whole machine, and there is no armrest and boarding grip on the front side, resulting in poor safety and convenience. Summary of the Utility Model

[0004] The purpose of the utility model is to solve the technical problems in the above background, and to propose a cab frame structure for a mini-excavator.

[0005] To achieve the above purpose, the utility model adopts the following technical scheme: A cab frame structure for a mini-excavator, including two lower cab frames. A first mounting plate is fixedly installed between the two lower cab frames. An upper cab frame is movably inserted between the two lower cab frames. A ceiling plate is fixedly installed between the inner walls on both sides of the upper cab frame. A second mounting plate is fixedly installed between the inner walls on both sides of the upper cab frame. A limiting device is provided on the outer wall surface of each of the two lower cab frames. The limiting device includes a sleeve, the sleeve is fixedly installed on the outer wall surface of the lower cab frame, a sliding rod is slidably connected inside the sleeve, and a vertical strip plate is fixedly installed on the surface of the sliding rod away from the sleeve. The settings of the sleeve and the sliding rod play a role in enabling the vertical strip plate to move smoothly.

[0006] Preferably, a spring is fixedly installed on the surface of the sleeve, and one end of the spring away from the sleeve is fixedly connected to the vertical strip plate. The setting of the spring plays a role in restricting the position of the vertical strip plate.

[0007] Preferably, a pull rod is fixedly installed on the surface of the vertical strip plate, a limiting rod is fixedly installed on the surface of the vertical strip plate away from the pull rod, and a limiting hole is provided on the outer wall surface of the upper cab frame. The settings of the limiting rod and the limiting hole play a role in limiting the upper cab frame inside the lower cab frame.

[0008] Preferably, an adjusting device is provided on the surface of the ceiling board. The adjusting device includes a notch opened on the surface of the ceiling board. A rotating shaft is rotatably connected between the inner walls on both sides of the notch, and a light-shielding board is fixedly installed on the outer wall surface of the rotating shaft. The setting of the rotating shaft enables the light-shielding board to rotate.

[0009] Preferably, a U-shaped plate is fixedly installed on the surface of the ceiling board. A threaded rod is rotatably connected between the inner walls at both ends of the U-shaped plate. A motor is fixedly installed on the surface of one end of the U-shaped plate, and the output end of the motor is fixedly connected to the threaded rod. The setting of the motor enables the threaded rod to rotate.

[0010] Preferably, a sliding rod is fixedly installed between the inner walls at both ends of the U-shaped plate. A movable plate is threadedly connected to the surface of the threaded rod.

The rack and the gear are meshed with each other. The setting of the rack enables the gear to rotate, and the setting of the gear enables the rotating shaft to rotate.

[0011] Compared with the prior art, the advantages and positive effects of the present utility model are as follows:

[0012] 1. In the present utility model, by providing a limiting device, when the device needs to be used, the entire device can be installed and fixed on the excavator by using the first mounting plate and the second mounting plate. Then, when the excavator is operating in a low space and the upper shed needs to be disassembled, first pull the pull rod. The movement of the pull rod drives the vertical strip board to move. The movement of the vertical strip board drives the sliding rod to move outward inside the sleeve and also drives the spring to stretch. At the same time, the movement of the vertical strip board also drives the limiting rod to move. The movement of the limiting rod causes it to move out of the inside of the limiting hole. The separation of the limiting rod and the limiting hole causes the upper shed and the lower shed to lose their limit. At this time, the upper shed can be pulled out from the inside of the lower shed to complete the disassembly operation between the upper shed and the lower shed. The lower shed remaining on the excavator can be used as a handrail for getting on the vehicle, which is convenient for the driver to get on the vehicle. In addition, it also plays a role in safety protection on both sides. Through the cooperation of the above structures, the device adopts an upper and lower split structure, and the upper part can be disassembled and assembled separately when actually needed, with the characteristics of convenient disassembly and assembly, safety and reliability.

[0013] 2. In the present utility model, by providing an adjusting device, when it is necessary to adjust the angle of the adjusting plate, first start the motor. The rotation of the motor drives the threaded rod to rotate. The rotation of the threaded rod drives the movable plate to move on the surface of the sliding rod. The movement of the movable plate on the surface of the sliding rod also drives the rack to move. The movement of the rack engages with the gear, thereby causing the gear to rotate. The rotation of the gear drives the rotating shaft to rotate. The rotation of the rotating shaft drives the light-shielding plate to rotate. When the light-shielding plate rotates to an appropriate angle, just turn off the motor. Through the cooperation of the above structure, the angle of the light-shielding plate can be adjusted, so that the light-shielding plate can better block light, further improving the practicability of the device.

[0026] In this embodiment: The settings of the sleeve 51 and the sliding rod 52 enable the vertical strip plate 53 to move smoothly.

[0027] Specifically, a spring 54 is fixedly installed on the surface of the sleeve 51, and one end of the spring 54 away from the sleeve 51 is fixedly connected to the vertical strip plate 53.

[0028] In this embodiment: The setting of the spring 54 restricts the position of the vertical strip plate 53.

[0029] Specifically, a pull rod 55 is fixedly installed on the surface of the vertical strip plate 53, a limiting rod 56 is fixedly installed on the end surface of the vertical strip plate 53 away from the pull rod 55, and a limiting hole 57 is opened on the outer wall surface of the upper shed frame 3. The settings of the limiting rod 56 and the limiting hole 57 limit the upper shed frame 3 inside the lower shed frame 1.

[0030] In this embodiment: An adjusting device 6 is provided on the surface of the ceiling panel 4. The adjusting device 6 includes a notch 601 which is opened on the surface of the ceiling panel 4. A rotating shaft 602 is rotatably connected between the inner walls on both sides of the notch 601, and a light-shielding plate 603 is fixedly installed on the outer wall surface of the rotating shaft 602. When the angle of the adjusting plate needs to be adjusted, first start the motor 606. The motor 606 drives the threaded rod 605 to rotate when it starts. The threaded rod 605 rotates to drive the movable plate 608 to move on the surface of the sliding rod 607. The movement of the movable plate 608 on the surface of the sliding rod 607 also drives the rack 609 to move. The rack 609 meshes with the gear 610, thereby causing the gear 610 to rotate. The rotation of the gear 610 drives the rotating shaft 602 to rotate, and the rotation of the rotating shaft 602 drives the light-shielding plate 603 to rotate. When the light-shielding plate 603 rotates to an appropriate angle, just turn off the motor 606. Through the cooperation of the above structure, the angle of the light-shielding plate 603 can be adjusted, so that the light-shielding plate 603 can better block light, further improving the practicality of the device.

[0031] Specifically, a U-shaped plate 604 is fixedly installed on the surface of the ceiling panel 4. A threaded rod 605 is rotatably connected between the inner walls at both ends of the U-shaped plate 604. A motor 606 is fixedly installed on the surface of one end of the U-shaped plate 604, and the output end of the motor 606 is fixedly connected to the threaded rod 605.

[0032] In this embodiment: The setting of the motor 606 has the effect of driving the threaded rod 605 to rotate.

[0033] Specifically, a sliding rod 607 is fixedly installed between the inner walls at both ends of the U-shaped plate 604. A movable plate 608 is threadedly connected to the surface of the threaded rod 605. A rack 609 is fixedly installed on the bottom surface of the movable plate 608. A gear 610 is fixedly installed on the outer wall surface of the rotating shaft 602, and the rack 609 and the gear 610 mesh with each other.

[0034] In this embodiment: The setting of the rack 609 has the effect of driving the gear 610 to rotate, and the setting of the gear 610 has the effect of driving the rotating shaft 602 to rotate.

[0035] Working principle: By setting the limit device 5, when the device needs to be used, the entire device can be installed and fixed on the excavator by using the first mounting plate 2 and the second mounting plate 7. Then, when the excavator is operating in a low space and the upper shed 3 needs to be disassembled, first pull the pull rod 55. The movement of the pull rod 55 drives the movement of the vertical strip plate 53. The movement of the vertical strip plate 53 drives the sliding rod 52 to move outward inside the sleeve 51 and at the same time drives the spring 54 to stretch. At the same time, the movement of the vertical strip plate 53 also drives the movement of the limit rod 56. The movement of the limit rod 56 causes it to move out of the inside of the limit hole 57. The separation of the limit rod 56 and the limit hole 57 causes the upper shed 3 and the lower shed 1 to lose the limit. At this time, the upper shed 3 can be pulled out from the inside of the lower shed 1 to complete the disassembly operation between the upper shed 3 and the lower shed 1. The lower shed 1 left on the excavator can be used as the handrail for getting on the vehicle, which is convenient for the driver to get on the vehicle and also plays a role in safety protection on both sides. Through the cooperation of the above structures, the device adopts an upper and lower split structure, and the upper part can be disassembled and assembled separately when actually needed, with the characteristics of convenient disassembly and assembly, safety and reliability. When the angle of the adjusting plate needs to be adjusted, first start the motor 606. The start of the motor 606 drives the rotation of the threaded rod 605. The rotation of the threaded rod 605 drives the movable plate 608 to move on the surface of the slide rod 607. The movement of the movable plate 608 on the surface of the slide rod 607 also drives the movement of the rack 609. The movement of the rack 609 meshes with the gear 610, and then the gear 610 rotates. The rotation of the gear 610 drives the rotation of the rotating shaft 602. The rotation of the rotating shaft 602 drives the rotation of the light-shielding plate 603. When the light-shielding plate 603 rotates to the appropriate angle, turn off the motor 606. Through the cooperation of the above structures, the angle of the light-shielding plate 603 can be adjusted, so that the light-shielding plate 603 can better block the light and further improve the practicability of the device.
