Description

Technical Field

[0001] This utility model relates to the field of jacking device technology, and in particular to a multifunctional jacking device for sand pillow slope repair construction. Background Technology

[0002] With the increasing emphasis on environmental protection by the country, a new technology for dam construction, which involves filling sand pillows underwater and then filling them with boulders, is gradually replacing the traditional method of riprap construction. This new technology accelerates the construction process and saves on investment. However, during waterway improvement, it is necessary to use the lifting device on the ship to drop sand pillows into the water.

[0003] The existing lifting platform is completely open. If a worker accidentally enters the lifting platform during lifting operations, they are very likely to lose their balance and fall into the sea, endangering their life.

[0004] To address these shortcomings, we proposed a multi-functional jacking device for sand pillow slope repair construction. Utility Model Content

[0005] The purpose of this invention is to overcome the shortcomings of the existing technology and provide a multifunctional jacking device for sand pillow slope repair construction.

[0012] This utility model has the following advantages:

[0013] (1) In this utility model, a projector and a receiver are installed on the upper surface of the lifting platform. During the lifting operation, the projector emits modulated infrared light, which is received by the receiver to form a protective net. When a worker enters the protective net, and the light is blocked by the worker, the receiver transmits the signal to the controller and controls the electric cylinder in the opposite direction to make the lifting platform fall back in time, preventing the worker from falling into the water due to instability. By setting a wireless transmission module inside the controller, the controller receives the control signal and controls the electric cylinder to work according to the received control signal, thereby realizing remote control of the lifting device, so that the operator can control it from a safe position away from the lifting platform.

[0014] (2) In this utility model, by setting an angle sensor and a weighing sensor, the tilt angle and load of the lifting platform are detected in real time, making the lifting device more automated and multifunctional. Attached Figure Description

[0025] like Figure 1-3As shown, a multifunctional jacking device for sand pillow slope repair construction includes a jacking platform 10. An electric cylinder 2 is fixed to the lower surface of the jacking platform 10 via a hinge. A fixing column 3 is provided on the lower surface of the jacking platform 10 and on one side of the electric cylinder 2. A mounting base 5 is fixed to the upper surface of the jacking platform 10, and multiple mounting bases 5 are provided. A projector 6 is fixed to the upper surface of one mounting base 5, and a receiver 7 for use with the projector 6 is provided on the upper surface of another mounting base 5. A loudspeaker 9 is provided on the upper surface of both the projector 6 and the receiver 7, and a buzzer 11 is provided on the side surface of both the projector 6 and the receiver 7. A controller 13 is provided on the side surface of the jacking platform 10, and a wireless transmission module is provided inside the controller 13.

[0026] In one embodiment, a projector 6 and a receiver 7 are installed on the upper surface of the lifting platform 10. During the lifting operation, the projector 6 emits modulated infrared light, which is received by the receiver 7, forming a protective net. When a worker enters the protective net and the light is blocked by the worker, the receiver 7 transmits a signal to the controller 13 and reverses the control of the electric cylinder 2, causing the lifting platform 10 to fall back in time, preventing the worker from falling into the water due to instability. At the same time, a wireless transmission module is installed inside the controller 13 to receive control signals. The controller 13 controls the electric cylinder 2 to work according to the received control signals, thereby realizing remote control of the lifting device, allowing the operator to control it from a safe position away from the lifting platform 10.

[0027] Specifically, the side surface of the lifting platform 10 is equipped with an angle sensor 4, and the lower surfaces of the electric cylinder 2 and the fixed column 3 are both welded with a load cell 1. The angle sensor 4 and the load cell 1 are both connected to the controller 13 through wires.

[0028] In one embodiment, by setting an angle sensor 4 and a load cell 1, the tilt angle and load of the lifting platform 10 are detected in real time, making the lifting device more automated and multifunctional.

[0029] Specifically, the upper surface of the lifting platform 10 is smooth.

[0030] In one embodiment, when the lifting platform 10 is tilted to a certain angle, the smooth surface reduces the friction between the sand pillow and the lifting platform 10, so that it can slide down the lifting platform 10 into the water.

[0031] Specifically, a fixed lifting lug is welded to the lower surface of the weighing sensor 1.

[0032] In one embodiment, the lifting device is secured to the ship using fixed lugs.

[0033] Specifically, the side surface of the lifting platform 10 is provided with protective pads 12.

[0034] In one embodiment, a protective pad 12 is provided to provide cushioning and protection, preventing workers from bumping into the side of the lifting platform 10 and causing damage.

[0035] Specifically, the side surface of the controller 13 is provided with control keys and status indicator lights 8.

[0036] In one embodiment, the control key is used to operate the controller 13 to control the lifting device, and the status indicator light 8 is used to display the working status of the lifting device.

[0037] The working process of this utility model is as follows: A projector 6 and a receiver 7 are installed on the upper surface of the lifting platform 10. During the lifting operation, the projector 6 emits modulated infrared light, which is received by the receiver 7, forming a protective net. When a worker enters the protective net, and the light is blocked by the worker, the receiver 7 transmits the signal to the controller 13 and controls the electric cylinder 2 in the opposite direction, causing the lifting platform 10 to fall back in time, preventing the worker from falling into the water due to instability. By installing a wireless transmission module inside the controller 13, the controller receives control signals and controls the electric cylinder 2 according to the received control signals, thereby realizing remote control of the lifting device. This allows the operator to control the device from a safe position away from the lifting platform 10. By installing an angle sensor 4 and a load cell 1, the tilt angle and load of the lifting platform 10 are detected in real time, making the lifting device more automated and multifunctional.

[0038] Although the present invention 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 invention should be included within the protection scope of the present invention.
