Description

Technical Field

[0001] This utility model relates to the field of mobile lifting work platform technology, and in particular to a reversing safety protection system for a mobile lifting work platform. Background Technology

[0002] The basic functions of a mobile lifting work platform include horizontal movement and vertical lifting. When moving horizontally, workers need to operate the control handle. Due to harsh construction site environments and frequent overlapping operations, workers may misoperate the handle, causing the equipment to move in the opposite direction, leading to accidents and injuries. Currently, mobile lifting work platforms manufactured do not have systematic safety features for the reversing function. Utility Model Content

[0003] To address the aforementioned problems, this utility model discloses a reversing safety protection system for a mobile lifting work platform.

[0004] The specific plan is as follows:

[0005] A reversing safety protection system for a mobile lifting work platform is characterized by comprising a mobile lifting work platform and an ECU, a forward solenoid valve, a reverse solenoid valve, and a control module installed on the mobile lifting work platform. The ECU is connected to the forward solenoid valve, the reverse solenoid valve, and the control module. The forward solenoid valve and the reverse solenoid valve control the forward and reverse movement of the mobile lifting work platform, respectively. The control module is used to control the on / off state of the circuits containing the forward and reverse solenoid valves.

[0006] Furthermore, the control module includes an operating handle, a front detection mechanism, and a rear detection mechanism. The operating handle is connected to the ECU, the front detection mechanism, and the rear detection mechanism, respectively. The front detection mechanism and the rear detection mechanism respectively identify whether the operating handle is mounted on the front and rear sides of the mobile lifting work platform. The ECU forms a circuit with the forward solenoid valve and the front detection mechanism, and the ECU forms a circuit with the reverse solenoid valve and the rear detection mechanism.

[0007] Furthermore, both the front detection mechanism and the rear detection mechanism are composed of an identification module and a switch connected in series. The identification module is used to detect whether the operating handle is in a specified position, including but not limited to four types of identification structural components: infrared, laser, radar, and mechanical.

[0008] Furthermore, the top surface of the mobile lifting work platform is provided with work railings along its edge, including a front railing, a rear railing, a left railing, and a right railing. The identification module of the front detection mechanism is located on the right front side of the mobile lifting work platform. When the two hook points of the operating handle are respectively hooked on the front railing and the right railing, the mobile lifting work platform can only move forward and cannot move backward. The identification module of the rear detection mechanism is located on the left rear side of the mobile lifting work platform. When the two hook points of the operating handle are respectively hooked on the rear railing and the left railing, the mobile lifting work platform can only move backward and cannot move forward.

[0009] Furthermore, the control module includes a foot pedal / manual handle, a front detection mechanism, and a rear detection mechanism, wherein the foot pedal / manual handle controls the on / off state of the circuits containing the forward solenoid valve and the backward solenoid valve, respectively.

[0010] Furthermore, the top surface of the mobile lifting work platform is provided with a work railing along the edge, wherein the foot pedal / manual handle is placed inside the work railing.

[0011] The beneficial effects of this utility model are as follows: This safety protection system has a simple structure and is easy to install. By switching the working circuit for the direction of movement on and off, it forcibly controls the movable direction of the equipment operating handle when it is mounted on different positions of the equipment or in different states of the mechanism. This prevents situations where the direction of movement is opposite to the actual required direction due to human negligence or misoperation. It also avoids collisions with facilities and personnel, preventing damage to facilities and personal injury. Attached Figure Description

[0014] The present invention will be further explained below with reference to the accompanying drawings and specific embodiments. It should be understood that the following specific embodiments are only used to illustrate the present invention and are not intended to limit the scope of the present invention.

[0015] This utility model provides a reversing safety protection system for a mobile lifting work platform, characterized in that it includes a mobile lifting work platform and an ECU, a forward solenoid valve, a reverse solenoid valve, and a control module installed on the mobile lifting work platform. The ECU is connected to the forward solenoid valve, the reverse solenoid valve, and the control module. The forward solenoid valve and the reverse solenoid valve control the forward and reverse movement of the mobile lifting work platform, respectively. The control module is used to control the on / off state of the circuits containing the forward and reverse solenoid valves. Example

[0016] like Figure 1 As shown, the control module of this embodiment includes an operating handle, a front detection mechanism, and a rear detection mechanism. The operating handle is connected to the ECU, the front detection mechanism, and the rear detection mechanism, respectively. The front detection mechanism and the rear detection mechanism respectively identify whether the operating handle is mounted on the front and rear sides of the mobile lifting work platform. The ECU forms a circuit with the forward solenoid valve and the front detection mechanism, and the ECU forms a circuit with the reverse solenoid valve and the rear detection mechanism.

[0017] In this embodiment, both the front detection mechanism and the rear detection mechanism are composed of an identification module and a switch connected in series. The identification module is used to detect whether the identification operation handle is in a specified position, including but not limited to four identification structural components: infrared, laser, radar and mechanical.

[0018] In this embodiment, the top surface of the mobile lifting work platform is equipped with guardrails along its edge, including a front guardrail, a rear guardrail, a left guardrail, and a right guardrail. The identification module of the front detection mechanism is located on the right front side of the mobile lifting work platform. When the two attachment points of the operating handle are respectively attached to the front and right guardrails, the mobile lifting work platform can only move forward and cannot move backward. The identification module of the rear detection mechanism is located on the left rear side of the mobile lifting work platform. When the two attachment points of the operating handle are respectively attached to the rear and left guardrails, the mobile lifting work platform can only move backward and cannot move forward. When the operating handle is attached to other parts of the guardrails, the mechanism cannot be triggered, and the moving action cannot be performed. This utility model uses existing electronic / mechanical components to design a new walking and moving working circuit, achieving this function by controlling the on / off state of the forward and backward circuits. Example

[0019] like Figure 2 As shown, the control module of this embodiment includes a foot pedal / manual handle, a front detection mechanism, and a rear detection mechanism. The foot pedal / manual handle controls the on / off state of the circuits containing the forward solenoid valve and the backward solenoid valve, respectively.

[0020] In this embodiment, the top surface of the mobile lifting work platform is equipped with a work railing along its edge, and the foot pedal / manual handle is placed inside the work railing. This utility model uses existing mechanical components to design a new walking and moving work circuit. By controlling the on / off state of the forward and backward circuits, when forward operation is required, the backward solenoid valve circuit is cut off, and the forward solenoid valve circuit is turned on; when backward operation is required, the forward solenoid valve circuit is cut off, and the backward solenoid valve circuit is turned on.

[0021] Furthermore, the application areas of this application include the fields of building engineering, municipal maintenance, industrial manufacturing, commercial services, and special industries. Building engineering applications include: high-altitude construction (exterior wall painting, glass curtain wall installation, steel structure welding); equipment installation (air conditioner outdoor units, ventilation ducts, fire protection facility commissioning); inspection and maintenance (factory roof repair, bridge bottom inspection).
