Description

Technical Field

[0001] The utility model is applicable to the field of leveling and lifting devices, and provides a vehicle-mounted automatic leveling and lifting device that can match a variety of measuring equipment. Background Art

[0002] In recent years, with the continuous deepening of the modernization of my country's emergency management system and capabilities, relying on the advantages of the national system, the emergency preparedness capacity has been continuously improved, withstood many severe tests, and explored and accumulated many useful experiences and practices. However, my country is a country with frequent and repeated natural disasters. It is in a stage of rapid development of industrialization and urbanization, and production safety is still in a period of climbing over hurdles. In particular, the complexity of emergencies has increased, and an emergency often triggers a series of secondary and derivative events. Sudden natural disaster rescue often has very limited on-site rescue forces, so the early on-site survey and measurement is very important. Good surveying and mapping results can become a decision-making map for the front line of command, so that limited rescue resources can be used on the cutting edge!

[0003] Traditional vehicle-mounted measurement systems often face some applicability defects when performing 3D laser scanning or total station measurement. First, the existing vehicle-mounted systems do not provide lifting functions, and the inertial navigation systems provided by manufacturers can often only match their own equipment models, making it difficult to achieve compatibility. Ordinary lifting equipment cannot automatically level, resulting in the inability to maintain a stable working state on uneven terrain. Secondly, different lifting systems are required for different types of measurement equipment, which increases the complexity and cost of the equipment. Utility Model Content

[0004] In view of the above-mentioned defects, the purpose of the utility model is to provide a vehicle-mounted automatic leveling and lifting device that can match a variety of measuring equipment, in order to solve the problems raised in the background technology. The device includes a leveling device and a lifting device that can lift the leveling device; the leveling device includes a first platform installed on the lifting device, and a supporting platform is installed on the first platform through a universal joint; two or more lifting devices are installed on the first platform, and the output end of the lifting device is connected to the supporting platform through an articulated rod, and the output end of the lifting device drives the supporting platform to tilt by pushing and pulling the articulated rod.

[0005] Furthermore, the lifting device includes a platform base, a telescopic main rod is hinged on the top of the platform base, one end of a hydraulic lifting rod is hinged on one side of the telescopic main rod, and the other end of the hydraulic lifting rod is hinged on the platform base.

[0006] Furthermore, the lifting device includes a stepper motor and a guide shaft installed on the top of the first platform, a screw shaft is installed on the output end of the stepper motor, a screw shaft is threadedly connected to a screw slider, and a linear bearing is sleeved on the guide shaft; the screw slider and the linear bearing are connected by a connecting piece; and the two ends of the articulated rod are respectively connected to the supporting platform and the connecting piece.

[0007] Furthermore, the articulated rod includes a connecting rod in the middle and ball heads at both ends, and the two ball heads are respectively connected to the connecting piece and the supporting platform ball head.

[0008] Furthermore, a universal shaft is installed on the top of the first platform via a support column.

[0009] Furthermore, the connection relationship between the two groups of lifting devices and the support platform is: the installation points of the two groups of lifting devices on the support platform are defined as point X and point Y respectively, the installation point of the universal joint on the support platform is defined as point O, and the point O is connected with point X and point Y to form lines OX and OY respectively, then OX is perpendicular to OY.

[0010] Furthermore, the connecting piece is an L-shaped structure, the linear bearing and the screw slider are both installed on the long part of the connecting piece of the L-shaped structure, and one end of the hinged rod is hinged on the short part of the connecting piece of the L-shaped structure.

When the device is in action, the hydraulic lifting rod is controlled to extend, so that the telescopic main rod is lifted to be perpendicular to the platform base. Then the telescopic main rod is controlled to extend, and the leveling device is lifted to a specified height. When the car is in a tilted position, the leveling device on the top of the car has a certain height, and its tilt angle will be greatly increased. At this time, the leveling device is required to adjust the surveying instrument on the top to the horizontal plane.

At the same time, the device has a simple structure and effectively reduces the production cost. BRIEF DESCRIPTION OF THE DRAWINGS

[0022] See also Figure 1-3 The purpose of the utility model is to provide a vehicle-mounted automatic leveling and lifting device that can match a variety of measuring equipment, including a lifting device and a leveling device 2 installed on the top of the lifting device, and a surveying instrument is installed on the leveling device 2. The lifting device can lift the leveling device 2 to a certain height.

[0023] The lifting device includes a platform base 1 installed on the top of the vehicle. The platform base 1 is an aluminum frame structure that can be fixedly connected to the roof of the car and parallel to the roof of the car. The top of the platform base 1 is fixedly connected with an equipment box 01. The equipment box 01 is used to load equipment such as electrical equipment and power devices.

[0024] The top of the platform base 1 is fixedly connected to a main rod base 11, and the top of the main rod base 11 is fixedly connected to an articulated seat 12, and a telescopic main rod 14 is articulated to the articulated seat 12. The telescopic main rod 14 is a telescopic device such as a telescopic gas rod or an electric telescopic rod. A telescopic hydraulic lifting rod 13 is articulated to one side of the telescopic main rod 14, and one end of the hydraulic lifting rod 13 is articulated to the telescopic main rod 14, and the other end is articulated to the platform base 1. When the hydraulic lifting rod 13 is in a retracted state, the telescopic main rod 14 is correspondingly in a state parallel to the platform base 1; when the hydraulic lifting rod 13 is extended, the telescopic main rod 14 is gradually lifted until it is perpendicular to the platform base 1.

[0025] The leveling device 2 includes a first platform 21 fixedly connected to the end of the telescopic main rod 14 away from the platform base 1, and a fixing column 211 and a supporting column 231 are fixedly connected to the top of the first platform 21. A second platform 22 is fixedly connected to the top of the fixing column 211, and the supporting column 231 passes through the second platform 22 and a supporting platform 23 is installed on the top through a universal shaft 232.

[0026] Two or more lifting devices are fixedly connected to the first platform 21. The lifting devices include a stepper motor 31 fixedly connected to the top of the first platform 21 and a guide shaft 35 fixedly connected between the first platform 21 and the second platform 22. The output end of the stepper motor 31 is vertically upward and fixedly connected to a screw shaft 32. Specifically, one end of the screw shaft 32 away from the stepper motor 31 is rotatably connected to the bottom of the second platform 22, and the stepper motor 31 can drive the screw shaft 32 to rotate. The screw shaft 32 is threadedly connected to a screw slider 33, and a linear bearing 36 is slidably sleeved on the guide shaft 35; the linear bearing 36 can slide up and down on the guide shaft 35. A connector 34 is fixedly connected to the top of the screw slider 33 and the linear bearing 36, that is, the lifting device also includes a connector 34, and a linear bearing 36 and a screw slider 33 are fixedly connected to the bottom of the connector 34. Therefore, the guide shaft 35 cooperates with the linear bearing 36 to complete the guiding function, and the stepper motor 31 drives the screw shaft 32 to rotate to make the screw slider 33 rise and fall, thereby realizing that the stepper motor 31 provides power to drive the connecting member 34 to move up and down.

[0027] A hinge rod 37 is installed between the connecting member 34 and the support platform 23, and the hinge rod 37 includes a connecting rod 372 and a ball head 371 fixedly connected to both ends of the connecting rod 372. The ball heads 371 at both ends of the connecting rod 372 are respectively connected to the connecting member 34 and the support platform 23. The ball head connection method can ensure that the support platform 23 maintains an effective hinge relationship with the hinge rod 37 when tilting. In this embodiment, the top surface of the support platform 23 is a square structure, and the universal shaft 232 is installed at the center of the bottom of the support platform 23; at the same time, the connection point between the hinge rod 37 of one group of lifting devices and the support platform 23 is located at the midpoint of one side of the support platform 23, and the connection point between the hinge rod 37 of the other group of lifting devices and the support platform 23 is located at the midpoint of a side perpendicular to the above-mentioned side of the support platform 23. Specifically, the connection relationship between the two lifting devices and the support platform 23 is as follows: the installation points of the two lifting devices on the support platform 23 are defined as point X and point Y respectively, the installation point of the universal joint 232 on the support platform 23 is defined as point O, and point O is connected with point X and point Y to form lines OX and OY, then OX is perpendicular to OY.

[0028] Preferably, the connecting member 34 is an L-shaped structure, the linear bearing 36 and the screw slider 33 are fixedly connected to the long part of the connecting member 34 of the L-shaped structure, and one end of the hinged rod 37 is hinged to the short part of the connecting member 34 of the L-shaped structure.

[0029] Preferably, a controller 02 is fixedly connected to the top of the first platform 21 , and the stepper motor 31 is electrically connected to the controller 02 .

[0030] Preferably, a tilt sensor is fixedly connected to the bottom of the support platform 23 , and the tilt sensor is electrically connected to the controller 02 .

[0031] In actual use, the platform base 1 can be installed on the top of the car, and a surveying and mapping instrument is installed on the top of the leveling device 2, which is loaded on the car for surveying and mapping work. The operator can use a remote control device to control the automatic leveling device. When the device is in action, the hydraulic lifting rod 13 is controlled to extend, so that the telescopic main rod 14 is lifted to be perpendicular to the platform base 1. Then the telescopic main rod 14 is controlled to extend to lift the leveling device to a specified height. When the car is in a tilted position, the leveling device on the top of the car has a certain height, and its tilt angle will be greatly increased. At this time, the leveling device 2 needs to be activated to adjust the surveying and mapping instrument on the top to a horizontal plane. During the process, the support column 231 plays the role of supporting the universal shaft 232 and the support platform 23. The support platform 23 can perform universal rotation under the support of the universal shaft 232. The tilt sensor sends the detected tilt angle information to the controller 02. The controller 02 controls the two stepper motors 31 to move, and the screw shaft 32 rotates. Under the guidance of the guide shaft 35 and the linear bearing 36, the screw slider 33 can move up and down along the length direction of the screw shaft 36, so that the connecting member 34 can also move up and down. The connecting member 34 can drive the hinge rod 37 to move, and indirectly tilt the support platform 23. At this time, the relationship between the two sets of lifting devices is: the installation points of the two sets of lifting devices on the support platform 23 are defined as point X and point Y respectively, and the installation point of the universal shaft 232 on the support platform 23 is defined as point O. Point O is connected with point X and point Y respectively. Lines OX and OY are formed, and OX is perpendicular to OY. In this way, the support platform 23 can be controlled in the spatial coordinate system where it is located. The support platform 23 is leveled by the stepper motor 31. During the leveling process, the tilt sensor implements the transmission of the tilt angle, and the controller 02 automatically controls the stepper motor 31.

[0032] Therefore, when the device is used for three-dimensional laser scanning or total station measurement, it can not only provide lifting and lowering functions, but also automatically adjust the level to ensure that the surveying and mapping instrument maintains a stable working state in uneven terrain. At the same time, the device has a simple structure and effectively reduces the production cost.

[0033] Of course, the present invention may have many other embodiments. Without departing from the spirit and essence of the present invention, technicians familiar with the field may make various corresponding changes and deformations based on the present invention, but these corresponding changes and deformations should all fall within the scope of protection of the claims attached to the present invention.
