Problems solved by technology
However, when adjusting the height of the existing lifting bracket, at least two people need to apply force at the same time to adjust the position between the upper column and the lower column. The labor intensity is relatively high, and the adjustment efficiency is low. It is easy to slide down quickly, the height adjustment is unstable, and there are safety hazards, which may even lead to irreversible consequences

Embodiment Construction
[0026] In order to explain the overall concept of the present invention more clearly, the following will be described in detail by way of examples in conjunction with the accompanying drawings.
[0027] In describing the present invention, it is to be understood that the terms "center", "upper", "lower", "front", "rear", "left", "right", "vertical", "horizontal", The orientation or positional relationship indicated by "top", "bottom", "inner", "outer", "axial", "radial" and "circumferential" are based on the orientation or positional relationship shown in the drawings, only It is for the convenience of describing the present invention and simplifying the description, but does not indicate or imply that the referred device or element must have a specific orientation, be constructed and operated in a specific orientation, and thus should not be construed as limiting the present invention.
[0028] In addition, the terms "first" and "second" are used for descriptive purposes only...

The invention discloses a portable gantry hoisting device. The portable gantry hoisting device comprises a main beam, stand column assemblies and a height adjusting assembly, wherein each stand columnassembly comprises a lower support and an upper stand column which is arranged on the lower support and vertically extends upwards; the upper ends of the upper stand columns are connected with the ends of the main beam; the two stand column assemblies support the two ends of the main beam correspondingly; the height adjusting assembly is arranged on the lower supports and connected with the lowerends of the upper stand columns; the height adjusting assembly has a first state and a second state; and the height adjusting assembly operated to be in the first state can drive the upper stand columns to do one-way ascending motion relative to the lower supports in the vertical direction, the height adjusting assembly operated to be in the second state can drive the upper stand columns to do one-way segmented descending motion relative to the lower supports in the vertical direction, and accordingly the height of the main beam is adjusted. According to the portable gantry hoisting device, through switching of the height adjusting assembly between the first state and the second state, rapid ascending and segmented stable descending of the upper stand columns are achieved, and the adjusting stability and the safety coefficient are effectively improved.
Description
technical field [0001] The invention belongs to the technical field of hoisting machinery equipment, and in particular relates to a portable gantry hoisting device. Background technique [0002] Lifting brackets are part of lifting machinery and equipment, widely used in industrial production in all walks of life, and different types of lifting brackets are used in different working environments. During use, in order to adapt to different working heights, it is often necessary to adjust the height of the lifting bracket. Most of the existing lifting brackets are divided into an upper column and a lower column. Adjustment holes are provided on the upper column, and the relative position between the upper column and the lower column is fixed by a locking member, so as to realize the height adjustment of the lifting bracket. However, when adjusting the height of the existing lifting bracket, at least two people need to apply force at the same time to adjust the position betwee...
