Description

Technical Field

[0001] This utility model relates to the field of hydraulic leveling technology, specifically to a hydraulic automatic leveling support system. Background Technology

[0002] As factories become increasingly mechanized and intelligent, they use lifting equipment. Lifting equipment is generally used for products that are large and difficult to handle manually. In some processing plants, materials need to be transported from low to high places, which is troublesome to do manually. Using forklifts to place pallets for lifting may be limited by space constraints, as forklifts cannot enter the site or move flexibly.

[0003] A hydraulic lifting platform disclosed in Chinese invention patent application CN111017832B can intuitively determine the position of the lateral deviation of the projected light by using a cross scale and a circular indicator ring, thereby intuitively understanding the amount of lateral deviation that occurs when the work platform is raised. However, this invention can only measure and indicate the angle of lateral deviation, but cannot level the lifting platform.

[0004] Therefore, it is necessary to propose a hydraulic automatic leveling support system to solve the above problems. Utility Model Content

[0005] To address the shortcomings of existing technologies, this utility model provides a hydraulic automatic leveling support system, which solves the problems mentioned in the background section.

[0006] To achieve the above objectives, this utility model is implemented through the following technical solution: it includes a chassis, with hydraulic cylinders provided at each of the four corners of the chassis, a hydraulic oil tank provided on one side of the top of the chassis, and a solenoid valve group for controlling the hydraulic cylinders fixedly connected to the side wall of the hydraulic oil tank.

[0007] A switch box is fixedly connected to the top of the hydraulic oil tank. A balance cylinder and an alarm are installed on the top of the switch box. A laser emitter is fixedly connected to the inner top wall of the balance cylinder via a wire. A conductive ring is fixedly connected to the middle side wall of the laser emitter. Four conductive rods are fixedly connected to the bottom wall of the balance cylinder. An arc-shaped plate that cooperates with the conductive ring to conduct electricity is fixedly connected to the top of the conductive rod.

[0008] Optionally, the inner top wall of the hydraulic cylinder is connected to a hydraulic column via a pull-back spring, the bottom of the hydraulic column penetrates the bottom wall of the hydraulic cylinder, and the bottom of the hydraulic column is hinged to a support plate via a hinge ball joint.

[0009] Optionally, a laser receiver for controlling an alarm is fixedly connected to the center of the inner bottom wall of the balance cylinder. The laser receiver is a Jidian LS03-S05, and the alarm includes a buzzer and an alarm light.

[0010] Optionally, the four arc-shaped plates correspond to the positions of the four hydraulic cylinders, and the switch box is equipped with a switch for controlling the solenoid valve group.

[0011] Optionally, the chassis has two front wheels symmetrically arranged on the front side and two omnidirectional wheels symmetrically arranged on the rear side. A handle frame is fixedly connected to the top of the rear side of the chassis, a control switch is provided on the handle frame, and a battery box is installed in the middle of the handle frame.

[0012] Optionally, a lifting frame is provided at the top center of the chassis, and a lifting platform is provided at the top of the lifting frame.

[0013] This utility model provides a hydraulic automatic leveling support system, which has the following beneficial effects:

[0014] 1. This hydraulic automatic leveling support system, by setting up a balance cylinder, can level the chassis by adjusting the verticality of the laser emitter inside the balance cylinder when using hydraulic cylinders for support, thereby achieving the purpose of horizontal support for the chassis.

[0015] 2. This hydraulic automatic leveling support system, by setting up a laser transmitter, can use the laser of the laser transmitter and the laser receiver to work together. When the tilt angle is too large and the arc plate contacts the conductive ring, the laser receiver will not receive the laser and will trigger an alarm, thereby reminding the staff that the system is in the leveling process, thus achieving the purpose of avoiding danger when working on an inclined surface.

[0022] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments.

[0023] Please see Figures 1 to 5 The present invention provides a technical solution: a hydraulic automatic leveling support system, including a chassis 1, with hydraulic cylinders 2 installed at the four corners of the chassis 1, a hydraulic oil tank 4 installed on one side of the top of the chassis 1, and a solenoid valve group 11 for controlling the hydraulic cylinders 2 fixedly connected to the side wall of the hydraulic oil tank 4.

[0024] A switch box 10 is fixedly connected to the top of the hydraulic oil tank 4. A balance cylinder 14 and an alarm are installed on the top of the switch box 10. A laser emitter 16 is fixedly connected to the inner top wall of the balance cylinder 14 through a wire 15. A conductive ring 20 is fixedly connected to the middle side wall of the laser emitter 16. Four conductive rods 18 are fixedly connected to the bottom wall of the balance cylinder 14. An arc-shaped piece 19 that cooperates with the conductive ring 20 to conduct electricity is fixedly connected to the top of the conductive rod 18.

[0025] The inner top wall of the hydraulic cylinder 2 is connected to a hydraulic column 22 by a return spring 21. The bottom of the hydraulic column 22 penetrates the bottom wall of the hydraulic cylinder 2. The bottom of the hydraulic column 22 is hinged to a support plate 24 by a hinge ball 23.

[0026] The four arc-shaped plates 19 correspond to the positions of the four hydraulic cylinders 2, and the switch box 10 is equipped with a switch to control the solenoid valve group 11.

[0027] In this embodiment, after the chassis 1 moves to the designated position, the oil pump inside the hydraulic oil tank 4 pumps out hydraulic oil. By introducing hydraulic oil into the hydraulic cylinder 2, the hydraulic column 22 extends out. The chassis 1 is then lifted by the support plate 24 supporting it on the ground. During the lifting process, if the chassis 1 is tilted, the arc-shaped plate 19, which is mounted on the chassis 1, will also tilt. However, the laser emitter 16 is suspended and can remain vertical. The conductive ring 20 on the side of the laser emitter 16 will connect with the arc-shaped plate 19 for electrical conduction. Since the four arc-shaped plates 19 correspond to the four hydraulic cylinders 2, the hydraulic cylinder 2 with the lowest position corresponding to the arc-shaped plate 19 in contact with the conductive ring 20 can open the valve of the hydraulic cylinder 2, controlling the extension of the lowest hydraulic cylinder 2, thereby achieving the purpose of automatic leveling.

[0028] In this embodiment, an electrical signal is generated after the arc-shaped piece 19 and the conductive ring 20 are connected. After the electrical signal is transmitted to the amplifier, the corresponding solenoid valve is closed. Hydraulic oil is injected into the lower-positioned hydraulic cylinder 2 through the solenoid valve inside the solenoid valve group 11, so as to achieve the purpose of leveling the chassis 1.

[0029] Specifically, a laser receiver 17 for controlling the alarm is fixedly connected to the center of the inner bottom wall of the balance cylinder 14. The laser receiver 17 is a Jidian LS03-S05, and the alarm includes a buzzer 12 and an alarm light 13.

[0030] In this embodiment, when the chassis 1 is tilted, the laser emitted by the laser emitter 16 cannot be received by the laser receiver 17. The laser receiver 17 is in a closed state, which triggers the alarm. The buzzer 12 and the alarm light 13 indicate to the staff that the system is in a leveling state, thereby avoiding the danger of working on a tilt.

[0031] Specifically, two front wheels 9 are symmetrically arranged on the front side of the chassis 1, two omnidirectional wheels 3 are symmetrically arranged on the rear side of the chassis 1, a handle frame 6 is fixedly connected to the top of the rear side of the chassis 1, a control switch is provided on the handle frame 6, and a battery box 5 is installed in the middle of the handle frame 6.

[0032] Specifically, a lifting frame 7 is installed in the middle of the top of the chassis 1, and a lifting platform 8 is installed on the top of the lifting frame 7.

[0033] In this embodiment, the electrical appliances are powered by the battery inside the battery box 5. When the front wheel 9 and the swivel wheel 3 are on the ground, the entire unit can be moved by pushing and pulling the handle frame 6. The switch on the handle frame 6 controls the power supply to the electrical appliances.

[0034] All of the above-mentioned electronic components are commonly used electronic components in the prior art, and their connection methods and working principles are all existing technologies, which will not be described in detail in this application.

[0035] The above description is only a preferred embodiment of the present utility model, but the protection scope of the present utility model is not limited thereto. Any equivalent substitutions or changes made by those skilled in the art within the technical scope disclosed in the present utility model, based on the technical solution and the inventive concept of the present utility model, should be included within the protection scope of the present utility model.
