Description

Technical Field

[0001] The utility model belongs to the technical field of electric lifting platforms, and particularly relates to an electric lift table with a safety guardrail. Background Technique

[0002] An electric lifting platform, namely an electric lift table, is a device widely used in occasions such as aerial work, cargo handling and loading and unloading. It realizes the lifting function through electric drive. According to different structures and uses, it can be divided into various types, such as mobile scissor lifts, self-propelled lift tables, articulated boom lift tables, etc. When in use, a guardrail needs to be fixed on the top of the electric lift table to prevent goods or workers from accidentally falling.

[0003] The existing electric lift tables are fixed to the guardrail by welding to increase the stability after the guardrail is fixed and improve its protection effect. However, the guardrail has the problem of being inconvenient to disassemble. Since the electric lift table occupies a large space during transportation and storage, the guardrail needs to be disassembled. When disassembling, workers need to use a cutting machine to cut the guardrail, and when in use, it needs to be welded again, which increases the work difficulty of the workers. Moreover, the strength of the guardrail becomes lower after multiple cutting and welding operations, increasing the danger of aerial work. Therefore, we provide an electric lift table with a safety guardrail to solve the above problems. Content of the Utility Model

[0004] The purpose of the utility model is to provide an electric lift table with a safety guardrail. Through the combined setting of a quick assembly and disassembly component and a pedal component, it solves the problem that the existing electric lift table with a safety guardrail does not have a quick assembly and disassembly function, and workers need to use a cutting machine to cut the guardrail when the electric lift table needs to be transported and stored.

[0005] To solve the above technical problems, the utility model is realized through the following technical solutions:

[0006] The utility model provides an electric lift table with a safety guardrail, which includes a lift table body, a quick assembly and disassembly component, and a pedal component. A guardrail body is arranged on the top of the lift table body, and positioning holes for cooperating with the guardrail body are respectively formed on the front side and the rear side of both sides of the top of the lift table body;

[0007] The quick assembly and disassembly component is arranged at the bottom of the lifting table body and includes a control box. Trapezoidal blocks are arranged on the front and rear sides of the inner cavity of the control box. A pull rod is fixedly connected to one side of each of the two trapezoidal blocks facing away from each other. The top of the pull rod penetrates through the top of the lifting table body and is movably connected to a first arc-shaped pull plate. The left side of the rear side of the inner cavity of the control box is movably connected to a screw rod. Threaded sleeves are threadedly connected to the front and rear sides of the surface of the screw rod. An extrusion block is fixedly connected to the top of the threaded sleeve. Long rod bolts are threadedly connected to the front and rear sides of the right side of the bottom of the lifting table body. The top of the long rod bolt is movably connected to a second arc-shaped pull plate;

[0008] The pedal component is arranged on the front and rear sides of the bottom of the guardrail body and includes a sliding sleeve. A baffle is fixedly connected to the top of the sliding sleeve. Fixed boxes are fixedly connected to the tops of the opposite sides of the two baffles. A clamping rod is arranged in the inner cavity of the fixed box. A spring is arranged between the two clamping rods. One side of each of the two clamping rods facing away from each other penetrates into the inner cavity of the guardrail body.

[0009] The present utility model is further arranged such that the front side of the screw rod penetrates through the control box and is fixedly connected to a knob, and the threads on the front and rear sides of the surface of the screw rod are opposite.

[0010] The present utility model is further arranged such that a chute is opened at the bottom of the control box. Sliders are slidably connected to the front and rear sides of the inner cavity of the chute. The top of the slider is fixedly connected to the threaded sleeve.

[0011] The present utility model is further arranged such that moving openings for cooperating with the pull rod are opened on the front and rear sides of the control box, and the top of the pull rod is movably connected to the first arc-shaped pull plate through a bearing.

[0012] The present utility model is further arranged such that positioning rods are fixedly connected to the front and rear sides of the top of the inner cavity of the control box, and the bottom of the positioning rod penetrates to the bottom of the pull rod.

[0013] The present utility model is further arranged such that limiting plates are fixedly connected to both sides of the spring, and one side of each of the two limiting plates facing away from each other is fixedly connected to the clamping rod.
