Convenient-to-use energy-saving type hoisting portal frame

Abstract

The invention discloses a convenient-to-use energy-saving type hoisting portal frame which comprises a top plate, a upport frame and a support plate, wherein the top plate is fixedly arranged above the support frame on two sides; a lifting motor is fixedly arranged in the middle of the lower surface of the top plate; a lifting rope is connected with the lower part of the lifting motor; a guardrailis connected with the lower part of the lifting rope; a netty bottom plate is arranged below the guardrail; the support plate is arranged below the netty bottom plate; and movable plates are arrangedin two I-shaped grooves in front of and at the back of the support plate. According to the convenient-to-use energy-saving type hoisting portal frame, the movable plates are arranged on the support plate and are fixed on the support plate through long screws; and when conveyed cargoes are fewer, the movable plates can be dismantled, so that weight of the support plate is reduced, energy is saved,and the corresponding conveying cost is reduced; the netty bottom plate is arranged on the support plate and the conveyed cargoes on the support plate can be placed in grids on the netty bottom plate, so that the conveyed cargoes are unlikely to slide off even if the support plate shakes, the protectiveness is higher and the convenient-to-use energy-saving type hoisting portal frame is suitable for popularization.

Description

technical field [0001] The invention relates to the technical field of building construction equipment, in particular to an energy-saving lifting gantry that is easy to use. Background technique [0002] The gantry is a new type of small lifting gantry developed according to the daily production needs of medium and small factories (companies) for handling equipment, warehouse import and export, lifting and maintenance of heavy equipment and material transportation. The image is like a dragon column, hence the name. It is suitable for making molds, auto repair factories, mines, civil construction sites and occasions that require lifting. It is commonly used in building construction as material transportation and construction personnel's upper and lower use to realize lifting mechanization. It can reduce manpower, reduce production and operation costs, and improve work efficiency, but it still has the following disadvantages in actual use: [0003] 1. The support plate of t...

AI Technical Summary

Problems solved by technology

[0003] 1. The support plate of the gantry is often fixed and integrated. If there are few equipment and other objects to be transported at one time, the support plate occupies most of the weight, which will cause waste of energy and increase the transportation cost;

[0004] 2. Due to the heavy support plate in the gantry frame, the support plate of the gantry frame may be unstable and shake when moving on the gantry. Possibility of falling, prone to safety accidents, low safety;

[0005] 3. When the support plate of the gantry shakes, the transported objects placed on the support plate are prone to shaking, and the transported objects are easily damaged when they touch each other or collide with the guardrail on the support plate, and the protection is low
