Description

Technical Field

[0001] The utility model relates to the technical field of emergency shelters, in particular to a shelter lifting device. Background Technique

[0002] In recent years, natural disasters such as heavy rain, floods and debris flows have become more and more frequent. The amount of water accumulated in a short time by these natural disasters is often beyond the capacity of the existing urban supporting drainage systems. Therefore, with the frequent occurrence of these natural disasters, various emergency drainage equipment has emerged to solve the problems of life and property safety caused by such natural disasters to the greatest extent.

[0003] At present, the standards for measuring an emergency drainage and rescue vehicle are mostly evaluated by the drainage volume per hour and the drainage head that the whole vehicle can provide. This has led to the development of most emergency drainage vehicles developed by emergency equipment units in the market towards large flow and high head. However, the larger the drainage volume per hour of an emergency drainage vehicle, the more drainage units are equipped on this vehicle, and the greater the power of the supporting power device. The increase in vehicle devices will directly lead to a larger external volume of the equipped vehicle model. In fact, more than 50% of the flood control and drainage occasions occur in urban communities, streets, underground parking lots and other places. In these places, one or two drainage units on a large emergency drainage vehicle can usually meet the drainage of a single point in the above-mentioned occasions. This has led to the idle of most resources on a large drainage vehicle. Once a problem occurs in the power device of such a vehicle model, it will lead to the shutdown of the drainage units of the whole vehicle. In addition, such a large drainage and rescue vehicle cannot reach narrow height-limited areas such as communities and underground parking lots in the first place.

[0004] At present, various emergency drainage shelters have also emerged on the market. After retrieval, a Chinese patent with the authorization announcement number CN218778704U discloses a lifting mechanism and a shelter. The lifting mechanism includes a leg cylinder, a leg frame, an outer frame, an inner frame, and at least two flexible traction members. The cylinder body of the leg cylinder is fixed within the leg frame, and the piston rod is hinged to the top of the outer frame. The outer frame is sleeved with the leg frame, and the leg frame is sleeved with the inner frame. The leg frame and the outer frame, and the outer frame and the inner frame can slide relative to each other along the telescopic direction of the leg cylinder. One end of one of the flexible traction members is fixed to the lower end of the outer frame, and the other end bypasses the top of the leg frame and is connected to the top of the inner frame. One end of the other flexible traction member is fixed to the lower end of the outer frame, and the other end bypasses the bottom of the leg frame and is connected to the top of the inner frame. The control unit is communicatively connected to the lifting mechanism, and the control unit can control the stable lifting of the lifting mechanism. The control unit includes a distance sensor, an XY two-way horizontal sensor, a controller, and an oil cylinder control valve group. The distance sensor, the XY two-way horizontal sensor, and the controller are arranged inside the shelter body. The oil cylinder of each lifting mechanism is connected to an oil cylinder control valve group, and the distance sensor, the XY two-way horizontal sensor, and the oil cylinder control valve group are respectively communicatively connected to the controller.

[0005] The above patent has the following technical problems:

[0006] As the power source for the leg telescoping, the leg cylinder depends on a supporting hydraulic system (hydraulic oil pump, hydraulic oil pipe, hydraulic valve group, etc.), which increases the volume and space occupancy of the equipment to a certain extent. Utility Model Content

[0007] Therefore, it is necessary to provide a shelter lifting device to solve the problem that the legs of the existing shelter using leg cylinders and cooperating with a hydraulic system will occupy a large space.

[0008] To achieve the above object, the present embodiment provides a shelter lifting device, including a cabin body, a lifting device, and a controller. The lifting device includes at least two lifting units, and at least two of the lifting units are symmetrically arranged with respect to the cabin body. The lifting unit includes a moving mechanism, an electric leg, and an inclination sensor. The side wall of the cabin body is connected to the electric leg through the moving mechanism. The moving mechanism is used to move the electric leg outward or inward. The inclination sensor is provided on the electric leg. The moving mechanism, the electric leg, and the inclination sensor are respectively connected to the controller.

[0009] Further, the electric outrigger includes a motor and a motor circuit board. The motor is connected to the motor circuit board. The lifting unit further includes a Hall sensor. The Hall sensor includes a Hall element and a Hall circuit board. The Hall element is connected to the stator of the motor. The Hall element is used to detect the rotation angle and direction of the output shaft of the motor. The Hall element is connected to the Hall circuit board. The Hall circuit board of the Hall sensor is connected to the motor circuit board. The motor circuit board is connected to the controller.

[0010] Further, the moving mechanism includes a link assembly and an electric push rod. The side wall of the cabin is connected to the electric outrigger through the link assembly. The link assembly is connected to the electric push rod. The electric push rod is used to drive the link assembly to vary the amplitude, so that the cabin rises or falls.

[0011] Further, the link assembly includes a first link and a second link. One end of the first link is hinged to the side wall of the cabin, and the other end of the first link is hinged to the electric outrigger. One end of the second link is hinged to the side wall of the cabin, and the other end of the second link is hinged to the electric outrigger. The first link and the second link are arranged up and down. One end of the electric push rod is hinged to the side wall of the cabin, and the other end of the electric push rod is hinged to the other end of the first link. The electric outrigger, the first link, the second link, and the cabin form a quadrilateral structure.

[0012] Further, the electric outrigger is perpendicular to the horizontal plane.

[0013] Further, there are four lifting units, namely a first lifting unit, a second lifting unit, a third lifting unit, and a fourth lifting unit. The first lifting unit and the second lifting unit are symmetrically arranged on the left and right side walls of the front part of the cabin. The third lifting unit and the fourth lifting unit are symmetrically arranged on the left and right side walls of the rear part of the cabin.

[0014] Further, a power supply is also included. The power supply is arranged in the cabin. The moving mechanism, the electric outrigger, the inclination sensor, and the controller are respectively connected to the power supply.

[0015] Further, the power supply includes a generator and a storage battery. The generator is arranged in the cabin. The generator is connected to the storage battery and used to supply power to the storage battery. The moving mechanism, the electric outrigger, the inclination sensor, and the controller are respectively connected to the storage battery.

[0016] Further, a hand pump is also included. The hand pump is connected to the storage battery.

[0017] Further, it also includes a control panel which is arranged on the cabin body and connected to the controller.

[0018] Different from the prior art, the above technical solution has the following beneficial effects:

[0019] The electric outriggers replace the traditional hydraulic outriggers, which not only reduces the dependence on external energy sources (such as hydraulic oil), only needs to be connected to the power supply to work, greatly reduces the environmental impact and usage cost, at the same time reduces the occupied space of the overall equipment, and improves the convenience of installation and transportation.

[0020] An inclination sensor is provided on each electric outrigger, which is responsible for real-time monitoring of the inclination angle of the outrigger and transmitting the data to the controller. The controller quickly calculates the necessary adjustment plan based on these real-time data and commands the corresponding electric outrigger to extend or retract until the cabin body reaches a horizontal state. Compared with the traditional horizontal sensor that levels through a complex hydraulic feedback control system, the inclination sensor can achieve a faster and more accurate automatic leveling function, significantly improving the work efficiency.

[0052] Please refer to Figures 1 to 2 , this embodiment provides a cabin lifting device, including a cabin body 1, a lifting device and a controller 4. The lifting device includes at least two lifting units 2. The at least two lifting units 2 are symmetrically arranged with respect to the cabin body 1. The lifting unit 2 includes a moving mechanism 21, an electric support leg 22 and an inclination sensor 23. The side wall of the cabin body 1 is connected to the electric support leg 22 through the moving mechanism 21. The moving mechanism 21 is used to move the electric support leg 22 outward or inward. An inclination sensor 23 is provided on the electric support leg 22. The moving mechanism 21, the electric support leg 22 and the inclination sensor 23 are respectively connected to the controller 4.

[0053] The cabin body 1 can be designed as a rectangular frame structure, which is convenient for accommodating various devices (such as drainage devices) or materials. The lifting device is specially designed to include at least two symmetrically arranged lifting units 2 to ensure the balance and stability of the cabin body 1 during lifting.

[0054] The moving mechanism 21 can adopt the design of a motor-driven telescopic rod, which can flexibly control the extension or retraction of the electric support leg 22. The electric support leg 22 replaces the traditional hydraulic support leg, not only reducing the dependence on external energy (such as hydraulic oil), only requiring access to the power supply 3 to work, greatly reducing the environmental impact and usage cost, while reducing the occupied space of the overall equipment and improving the convenience of installation and transportation.

[0055] An inclination sensor 23 is provided on each electric support leg 22, which is responsible for real-time monitoring of the inclination angle of the support leg and transmitting the data to the controller 4. The controller 4 calculates the necessary adjustment plan quickly based on these real-time data and commands the corresponding electric support leg 22 to extend or retract until the cabin body 1 reaches a horizontal state. Compared with the traditional horizontal sensor that levels through a complex hydraulic feedback control system, the inclination sensor 23 can achieve a faster and more accurate automatic leveling function, significantly improving the work efficiency.

[0056] Please refer to Figures 1 to 2 , in this embodiment, the electric support leg 22 includes a motor 225, a motor circuit board, a gearbox 226, a lead screw, a telescopic tube and a fixed tube 227. The motor circuit board and the gearbox 226 can be provided inside the fixed tube 227. The motor 225 is connected to the motor circuit board. The motor 225 is connected to the lead screw through the gearbox 226. A nut is threadedly connected to the lead screw. The nut is connected to the inner wall of the fixed tube 227 through a linear slide rail. The nut is connected to the telescopic tube. One end of the telescopic tube away from the motor 225 is connected to a support leg arm 228. A foot pad for abutting against the ground is provided at the bottom of the support leg arm 228.

[0057] Please refer to Figure 3, in this embodiment, the lifting unit 2 further includes a Hall sensor. The Hall sensor includes a Hall element 24 and a Hall circuit board. The Hall element 24 is connected to the stator 2251 of the motor 225. The Hall element 24 is used to detect the rotation angle and direction of the output shaft of the motor 225. The Hall element 24 is connected to the Hall circuit board. The Hall sensor circuit board of the Hall sensor is connected to the controller 4. The controller 4 controls the telescopic speed and distance of the electric leg 22 by detecting the rotation angle and direction information of the output shaft of the motor 225 through the Hall sensor circuit board. The Hall sensor further includes a Hall code disk. The Hall code disk is connected to and coaxially arranged with the output shaft of the motor 225, and is connected to the Hall circuit board. It should be noted that an inclination sensor 23 and a Hall sensor are provided on each electric leg 22.

[0058] The motor 225 receives the control signal from the controller 4 through the motor circuit board. The motor circuit board is responsible for parsing the instructions sent by the controller 4 and converting these instructions into signals that the motor 225 can understand to drive the motor 225 to operate. The Hall sensor uses the Hall effect to measure the rotation angle and direction of the output shaft of the motor 225. When the motor 225 rotates, the Hall code disk also rotates accordingly. Different magnetic poles on the Hall code disk cause the Hall element 24 to generate different voltage signals. The signals detected by the Hall element 24 reflect the real-time rotation angle and direction of the output shaft of the motor 225, and these signals are transmitted to the controller 4 for parsing. The controller 4 dynamically adjusts the telescopic speed and distance of the electric leg 22 according to the rotation angle and direction information provided by the Hall sensor to ensure the accuracy and stability of the lifting process.

[0059] Please refer to Figures 1 to 2 , in this embodiment, the moving mechanism 21 includes a link assembly and an electric push rod 213. The side wall of the cabin 1 is connected to the electric leg 22 through the link assembly. The link assembly is connected to the electric push rod 213. The telescopic rod is used to drive the link assembly to change its amplitude so that the electric leg 22 moves outward or inward.

[0060] The link assembly connects the side wall of the cabin 1 and the electric leg 22, allowing the electric leg 22 to move to a suitable position. Subsequently, the electric leg 22 presses against the ground downward for telescopic movement. The multi-joint design of the link assembly effectively disperses the torque during the movement process, reduces the risk of excessive single-point stress, and increases the stability and durability of the entire lifting system. The electric push rod 213, as the core power source, converts its linear motion into the amplitude change motion of the link assembly, thereby pushing the electric leg 22 to move smoothly outward or inward along a predetermined trajectory. Compared with hydraulic or pneumatic systems, the electric push rod 213 reduces the risk of oil leakage or air leakage, simplifies the maintenance work, and also saves the space occupied by the equipment.

[0061] Please refer to Figures 1 to 2, in this embodiment, the link assembly includes a first link 211 and a second link 212. One end of the first link 211 is hinged to the side wall of the cabin 1, and the other end of the first link 211 is hinged to the electric leg 22. One end of the second link 212 is hinged to the side wall of the cabin 1, and the other end of the second link 212 is hinged to the electric leg 22. The first link 211 and the second link 212 are arranged vertically. One end of the electric push rod 213 is hinged to the side wall of the cabin 1, and the other end of the electric push rod 213 is hinged to the other end of the first link 211. The electric leg 22, the first link 211, the second link 212, and the cabin 1 form a quadrilateral structure.

[0062] After the control system issues an instruction, the electric push rod 213 starts, and through the linear pushing force, the first link 211 is moved along a predetermined path. Since the first link 211 and the second link 212 form a quadrilateral structure through the electric leg 22, the movement of the first link 211 will drive the second link 212 to change synchronously. The two work together to achieve smooth and synchronous extension or retraction of the electric leg 22.

[0063] Please refer to Figures 1 to 2 , in this embodiment, the electric leg 22 is perpendicular to the horizontal plane to ensure that the cabin 1 is in a stable posture.

[0064] Please refer to Figures 4 to 5 , in this embodiment, there are four lifting units 2, namely the first lifting unit, the second lifting unit, the third lifting unit, and the fourth lifting unit. The first lifting unit and the second lifting unit are symmetrically arranged on the left and right side walls of the front part of the cabin 1, and the third lifting unit and the fourth lifting unit are symmetrically arranged on the left and right side walls of the rear part of the cabin 1. The first lifting unit, the second lifting unit, the third lifting unit, and the fourth lifting unit are located at the four vertices of a virtual quadrilateral. The four-point symmetric layout ensures that the cabin 1 is evenly stressed during the lifting process. The independent operation ability of the four lifting units 2 allows the equipment to flexibly respond under different terrain conditions. Even if the ground is uneven in hardness or has a slope, it can achieve stable lifting through intelligent adjustment, expanding the application range. Among them, the electric leg of the first lifting unit is the first electric leg 221, the electric leg of the second lifting unit is the second electric leg 222, the electric leg of the third lifting unit is the third electric leg 223, and the electric leg of the fourth lifting unit is the fourth electric leg 224. In some embodiments, there are three, five, six, etc. lifting units.

[0065] Please refer to Figure 6, in this embodiment, the mobile cabin lifting device further includes a control panel 5, which is arranged on the cabin body 1 and connected to the controller 4. The control panel 5 is directly installed at an appropriate position on the cabin body 1, facilitating the operator to intuitively control and monitor various functions. The control panel 5 is connected to the controller 4 through wired or wireless communication methods, ensuring the immediate transmission and execution of operation instructions. As a human-machine interface, the control panel 5 integrates a display module and an input module. The display module can display the device status information in real time, such as the current telescopic state of the electric support legs, the levelness of the cabin body 1, the remaining power of the power supply 3 and other key parameters, enabling the operator to clearly understand the operation status of the device at a glance. The input module includes buttons, knobs or touch screens, etc., allowing the operator to input instructions as needed, such as telescoping the electric support legs 22, lifting the cabin body 1, adjusting the speed, etc. After being processed by the processor built into the control panel 5, these instructions are sent to the controller 4 in the form of digital signals, and the controller 4 then analyzes and executes the corresponding operations, such as adjusting the rotation speed of the motor 225 of the electric support legs 22, controlling the movement of the electric push rod 213, etc., to achieve precise control of the entire mobile cabin lifting device.

[0066] In this embodiment, the controller 4 can be an MCU (Microcontroller Unit), which is an integrated circuit chip that integrates key components such as a central processing unit (CPU), memory (RAM and ROM), and input / output (I / O) interfaces on one chip to form a complete microcomputer system.

[0067] Please refer to Figure 6 , in this embodiment, the mobile cabin lifting device further includes a power supply 3, which is arranged inside the cabin body 1. The moving mechanism 21, the electric support legs 22, the inclination sensor 23, the controller 4, the electric push rod 213, and the control panel 5 are respectively connected to the power supply 3. After the mobile cabin lifting device is started through the power supply 3 integrated in the cabin, the power supply 3 distributes the required electric energy to each working component, and the transmission of the power supply 3 is realized through cables. The power supply 3 inside the cabin can be used for the electric support legs 22. Compared with the traditional hydraulic system, it can reduce equipment redundancy, save space and cost, and improve energy utilization efficiency.

[0068] Please refer to Figure 6, in this embodiment, the power supply 3 includes a generator 31 and a storage battery 32. The generator 31 is arranged inside the cabin body 1. The generator 31 is connected to the storage battery 32 and is used to supply power to the storage battery 32. The moving mechanism 21, the electric support legs 22, the inclination sensor 23, the controller 4, and the control panel 5 are respectively connected to the storage battery 32. The generator 31 is placed inside the cabin body 1 and is connected to the storage battery 32, mainly responsible for charging the storage battery 32, ensuring that even in the case of no external power supply 3 being connected, the cabin lifting equipment can still rely on the storage battery 32 to maintain normal operation. The moving mechanism 21, the electric support legs 22, the inclination sensor 23, the controller 4, and the control panel 5 are all connected to the storage battery 32 to obtain the necessary electrical energy from here.

[0069] In this embodiment, the cabin lifting equipment further includes a drainage device. The drainage device includes a hand pump, and the hand pump is connected to the storage battery 32. The hand pump is driven by a built-in motor, and this motor is directly powered by the storage battery 32 inside the cabin. When drainage or water supply operations are required, the operator only needs to start the hand pump, and the storage battery 32 releases electrical energy to the motor of the hand pump, and the motor then drives the pump body to work, realizing the effective transportation of liquid substances. The immediate availability of the hand pump, especially in the case of power failure or emergency, can quickly drain accumulated water. In some embodiments, the drainage device can also be a large mobile pumping station driven by electricity.

[0070] In this embodiment, traditional hydraulic support legs cannot determine whether they are in contact with the ground and need to be observed by the human eye. This application uses electric support legs 22. When the electric support legs 22 have no load (that is, the electric support legs 22 are not extended and not in contact with the ground), the current of the motor is X. When the electric support legs 22 touch the ground, due to doing work to support the cabin body 1, the load becomes larger, and the motor current is Y. When the currents of the motors of all the electric support legs 22 are Y (the Y current is allowed to have differences), at this time X is less than Y, and thus it can be determined whether the support legs touch the ground through the motor circuit board.

[0071] In this embodiment, the inclination sensor can select the CK-IMJ-190 dual-axis inclination sensor.

[0072] For the convenience of readers' understanding, the leveling principle of the cabin lifting equipment is described here:

[0073] Assume that when the vertical angle of each support leg is Y0 and the horizontal direction is X0, the cabin is in a level state. The angles detected by the inclination sensors corresponding to the four electric support legs are X1, X2, X3, X4, and Y1, Y2, Y3, Y4 respectively.

[0074] When -X1 ≤ X0 ≤ X1, -Y1 ≤ Y0 ≤ Y1, -X2 ≤ X0 ≤ X2, -Y2 ≤ Y0 ≤ Y2, -X3 ≤ X0 ≤ X3, -Y3 ≤ Y0 ≤ Y3, the controller controls the extension speed and distance of the outriggers through the Hall sensors inside the electric outriggers, ensuring that the four electric outriggers extend at the same speed and distance simultaneously, and reaching a horizontal state at this time.

[0075] When X0 > X1, -Y1 ≤ Y0 ≤ Y1, -Y2 ≤ Y0 ≤ Y2, -Y3 ≤ Y0 ≤ Y3, -Y4 ≤ Y0 ≤ Y4, the extension speed of the first electric outrigger is increased and the extension distance is lengthened through the Hall sensor inside the first electric outrigger. At the same time, the extension speed of the opposite second electric outrigger can be adjusted to slow down and the extension distance can be shortened, so that -X1 ≤ X0 ≤ X1.
