Description

Technical Field

[0001] This utility model relates to the field of command and control cabins, and in particular to a liftable floor for command and control cabins. Background Technology

[0002] In fields such as emergency command, military dispatch, and disaster relief, command modules serve as mobile core command hubs, and the stability, load-bearing capacity, and spatial adaptability of their internal floor structure are crucial to command efficiency.

[0003] Currently, some liftable floor devices achieve their lifting function solely through a direct connection between the lift and the floor. This means they rely solely on the extension and retraction of the lift's output shaft to support and drive the floor. With only a single point or a few points connecting the lift to the floor, the floor is prone to shaking or even localized deformation when it is carrying equipment, personnel, or in a bumpy environment. This affects the safety of equipment operation and the stability of personnel handling. Furthermore, the lift's output shaft must simultaneously bear both driving and load-bearing functions, leading to accelerated mechanical wear due to prolonged high-load use. Therefore, a liftable floor for command and control cabins is proposed to address these issues. Utility Model Content

[0004] To overcome the above shortcomings, this utility model provides a liftable floor for a command cabin, which aims to solve the problem in the prior art that "the floor is directly supported and driven by a lift, and the lift simultaneously bears the driving and load-bearing functions, resulting in accelerated mechanical wear".

[0005] To achieve the above objectives, the present invention adopts the following technical solution: a liftable floor for a command cabin, comprising a main cabin, extension cabins slidably connected to the left and right sides of the main cabin, a floor provided on the lower inner wall of the main cabin, a reduction motor fixedly installed on the lower inner wall of the main cabin, a transmission rod fixedly installed on the output end of the reduction motor, a lift fixedly installed on both the front and rear sides of the transmission rod, the output shaft of the lift fixedly installed on the lower part of the floor through an auxiliary component, the lift fixedly installed on the inner wall of the main cabin, and a transmission component fixedly installed on the outer side of the output shaft of the lift;

[0006] The transmission assembly includes a connecting plate fixedly installed on the outside of the elevator output shaft. Transmission components are provided on the left and right sides of the connecting plate. A sliding groove is provided on the side of the transmission component near the connecting plate. The connecting plate is slidably connected to the inner wall of the sliding groove. An abutment is fixedly installed on the outside of the transmission component. A base is slidably connected to the lower part of the abutment. The base is fixedly installed on the inner wall of the main cabin.

[0007] As a further description of the above technical solution:

[0008] The transmission component is bent on the side near the connecting plate.

[0009] As a further description of the above technical solution:

[0010] The transmission components are provided in multiple sets, and adjacent sets of the transmission components are fixedly connected by connecting rods.

[0011] As a further description of the above technical solution:

[0012] The side of the abutment member away from the transmission member is set as an inclined surface.

[0013] As a further description of the above technical solution:

[0014] The upper part of the abutment abuts against the lower part of the floor.

[0015] As a further description of the above technical solution:

[0016] The auxiliary component includes a slide plate, which is fixedly connected to the top of the elevator output shaft. A connecting sleeve is slidably connected to the outside of the slide plate, and the upper part of the connecting sleeve is fixedly connected to the bottom of the floor.

[0017] As a further description of the above technical solution:

[0018] The floor is fixedly equipped with reinforcing ribs at the bottom.

[0019] This utility model has the following beneficial effects:

[0020] 1. In this utility model, the floor can be stably raised and lowered by the cooperation of the geared motor, transmission rod, and lifting mechanism. At the same time, the transmission components enable the lifting mechanism to provide multi-point support to the floor through the connecting plate, transmission components, and abutment components when driving the floor to rise and fall, thereby enhancing the stability and load-bearing capacity of the floor and reducing the operating pressure on the lifting mechanism.

[0021] 2. In this utility model, by using the auxiliary components and the transmission components in combination, when the floor is reset, the sliding plate slides on the inner wall of the connecting sleeve, so that when the output end of the elevator moves downward, it first drives the connecting plate to move, so that the abutment part is separated from the floor, and then drives the floor to move downward, so that the device runs smoothly.

[0028] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0029] Reference Figures 1-3 This utility model provides an embodiment of a liftable floor for a command cabin, comprising a main cabin 1, which serves as the main structure of the command cabin and provides the installation foundation and support for other components. Extension cabins 2 are slidably connected to the left and right sides of the main cabin 1, allowing for expansion of the cabin space and increasing the usable area of ​​the command cabin. A floor 3 is provided on the lower inner wall of the main cabin 1, serving as the load-bearing surface for personnel movement and equipment placement. A geared motor 4, consisting of a motor and a reducer, is fixedly installed on the lower inner wall of the main cabin 1, acting as a power source. It drives a transmission rod 5 to rotate via its output end, providing power for the lifting and lowering of the floor 3. The geared motor 4 outputs... A transmission rod 5 is fixedly installed at one end, connecting the output end of the geared motor 4 to the elevator 6, transmitting the power of the geared motor 4 to the elevator 6, so that the elevator 6 works synchronously. The elevator 6 is fixedly installed on both the front and rear sides of the transmission rod 5. It is a worm gear transmission and is driven by the transmission rod 5. Its output shaft is connected to the lower part of the floor 3 through the auxiliary component 9, directly driving the floor 3 to perform lifting and lowering movements. At the same time, the transmission component 7 installed on the outside of the output shaft can help improve the stability of the floor 3. The output shaft of the elevator 6 is fixedly installed on the lower part of the floor 3 through the auxiliary component 9. The elevator 6 is fixed to the inner wall of the main cabin 1. The transmission component 7 is fixedly installed on the outside of the output shaft of the elevator 6.

[0030] Reference Figures 2-4The transmission assembly 7 includes a connecting plate 71 fixedly installed on the outside of the output shaft of the elevator 6. When the elevator 6 is working, it drives the connecting plate 71 to move. Transmission components 72 are provided on the left and right sides of the connecting plate 71. When the connecting plate 71 moves, it can drive the transmission components 72 and the abutment components 75 to slide on the base 74. The side of the transmission component 72 near the connecting plate 71 has a groove 73, which provides guidance and space for the relative sliding between the connecting plate 71 and the transmission component 72. The connecting plate 71 is slidably connected to the inner wall of the groove 73. The abutment component 75 is fixedly installed on the outside of the transmission component 72, which provides support for the floor 3 after it rises. To enhance the stability of floor 3 during lifting, a base 74 is slidably connected to the lower part of the abutment 75, providing a sliding guide for the abutment 75. The base 74 is fixedly installed on the inner wall of the main cabin 1. The side of the transmission component 72 near the connecting plate 71 is bent. Multiple sets of transmission components 72 are provided, and adjacent sets of transmission components 72 are fixedly connected by a connecting rod, enabling synchronous movement. This provides more stable and uniform support for floor 3 during lifting, enhancing the overall transmission effect and structural stability of the transmission assembly 7. The side of the abutment 75 away from the transmission component 72 is set as an inclined surface, and the upper part of the abutment 75 abuts against the lower part of floor 3.

[0031] Reference Figures 2-4 The auxiliary component 9 includes a sliding plate 91, which is fixedly connected to the top of the output shaft of the elevator 6. The diameter of the sliding plate 91 is larger than the diameter of the output shaft of the elevator 6. A connecting sleeve 92 is slidably connected to the outside of the sliding plate 91. The upper part of the connecting sleeve 92 is fixedly connected to the bottom of the floor 3. The sliding plate 91 slides on the inner wall of the connecting sleeve 92. When the elevator 6 moves upward, the elevator 6 drives the sliding plate 91 to directly support the lower side of the floor 3. When the floor 3 descends, the elevator 6 first drives the sliding plate 91 to slide on the inner wall of the connecting sleeve 92. At this time, no downward pulling force is applied to the floor 3, and the floor 3 is supported by the abutment 75. At this time, the output shaft of the elevator 6 drives the connecting plate 71 to move downward, so that the abutment 75 first disengages from the floor 3. A reinforcing rib 8 is fixedly installed on the lower part of the floor 3, which can improve the structural strength and load-bearing capacity of the floor 3, prevent the floor 3 from deforming due to excessive force, and extend the service life of the floor 3.

[0032] Working principle: When in use, the geared motor 4 starts, and its output end drives the transmission rod 5 to rotate. The transmission rod 5 transmits power to the front and rear lifting platforms 6, driving the output shaft of the lifting platform 6 to extend upward. At this time, the slide plate 91 rises with the output shaft of the lifting platform 6 and slides against the inner wall of the connecting sleeve 92, causing the floor 3 to rise steadily.

[0033] At the same time, the connecting plate 71 on the outside of the output shaft of the elevator 6 moves upward with the output shaft. Since the connecting plate 71 is slidably connected in the groove 73 of the transmission component 72, it will push the transmission component 72 to move outward.

[0034] The transmission component 72 drives the abutment component 75 to slide along the base 74 until the upper part of the abutment component 75 abuts against the lower part of the floor 3, forming multi-point support and enhancing the load-bearing stability of the floor 3 after it rises.

[0035] When floor 3 descends, the reduction motor 4 rotates in reverse, driving the output shaft of the elevator 6 to retract downwards via the transmission rod 5. The output shaft of the elevator 6 first drives the connecting plate 71 to move downwards. Due to the bending structure of the transmission component 72 and the guiding effect of the slide groove 73, the connecting plate 71 pulls the transmission component 72 to move inwards, causing the abutment 75 to disengage from the lower part of floor 3 and release the support.

[0036] During this process, the slide plate 91 of the auxiliary component 9 slides downward within the connecting sleeve 92, without directly pulling the floor 3, ensuring that the abutment 75 disengages first before the floor 3 descends, thus avoiding structural interference. Once the abutment 75 has completely disengaged, the output shaft of the elevator 6 slides through the slide plate 91 to the bottom of the connecting sleeve 92, causing the floor 3 to descend smoothly until it returns to its initial position.

[0037] Finally, it should be noted that the above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
