Abstract
The utility model relates to a simple and manual lifting rod which is fixed with ground by a base plate and is used for supporting an inner-wall cylinder to move up and down inside. The inner-wall cylinder is used to mount measurement devices and can contact with the inner wall of an outer-wall cylinder in a rolling way through a pulley. A wire-winding box is arranged outside the outer-wall cylinder and connected with a pulley group in a rolling way through a traction rope. A fastening screw passes through the wall of the outer-wall cylinder and can be used for positioning and fastening the inner-wall cylinder and the outer-wall cylinder. The lifting rod solves the height differences between measurement points and the crown layer of trees. In the variable environment and according to the growth situation of trees, the lifting rod can be adjusted manually to reach the best effect for measuring environment, thereby keeping the measuring standard of the distance height of measurement points and the crown layer of trees, further improving the reliability of measured data, and totally solving the height differences between measurement points and the crown layer of trees. In addition, the lifting rod has the advantages of simple structure, low cost, high flexibility and simple operation.
Description
Technical field
The utility model relates to a kind of lifting mechanism that is used to carry measurement mechanism, specifically a kind of manual simplified lifting bar of adjusting the measurement point height.
Background technology
The lifting mechanism of carrying measurement mechanism has various ways, and is very extensive in industry purposes such as exploration, oil field, illuminating lamps, and oil pressure type, air-pressure type, power type etc. are arranged, and specifically comprises screw rod lifting bar, square lifting bar and trellis tower etc.The lifting bar parameter comprises height overall, wind loading rating, vertical bearing, unbalance loading, lifting time, beat requirement, weight and installation etc.
Lifting bar requires differently in scientific research to it, particularly in ecology environment research, at first will measure relevant fundamental, such as wind direction, wind speed, moisture conditions, solar radiation, gas concentration lwevel, humiture, air pressure etc.In the forestry ecological Studies, measure forest lower floor, the data on forest middle level and forest upper strata, when especially surveying the forest upper layer data, require measuring point to remain at the distance of about 2 meters of forest layer over top, but forest in the season of growth when almost per all in growth, if during 1 meter of the annual growth of forest, measuring point just must raise 1 meter, could keep distance with forest top layer measurement point, must raise about 2 meters in 2 years, if when building measuring staff altitude hold, will consider the diff-H problem of measuring point and woods layer in the month at 2-3, if the height of untimely rising measuring point, the precision of measurement will be affected.
According to the growing state of forest, every year in growth period, must promote measurement point 2-3 time, could satisfy the requirement for height of measurement point.And existing lifting mechanism complex structure, cost height, operation inconvenience.
The utility model content
At defectives such as the lifting rod structure complexity of the carrying measurement mechanism that exists in the present technology, cost height, the technical problems to be solved in the utility model provides a kind of simple in structure, easy to operate manual simplified lifting bar.
For solving the problems of the technologies described above, the technical solution adopted in the utility model is:
The manual simplified lifting bar of the utility model comprises:
The outer wall tube is fixed by base plate and ground, is used to support inwall tube portion's lifting moving within it;
The inwall tube, its top is used to install and measure device, by pulley and outer wall tube inwall rolling touch;
The spiral case is located at outer wall tube outside, and rolling with assembly pulley by hauling rope is connected;
Tighten up screw, be arranged on the barrel of outer wall tube, be used for the positioning and fastening between inwall tube and the outer wall tube.
Described pulley comprises two fixed pulleys that are fixedly arranged on outer wall tube top, is fixedly arranged on a plurality of movable pulleys of inwall drum outer wall and the fixed pulley that is fixedly arranged on inwall tube bottom; Described outer wall tube or inwall tube are that iron, aluminium, corrosion-resistant steel or alloy material are made; Described outer wall tube equates with inwall tube length degree.
The utlity model has following beneficial effect and advantage:
1. efficiently solve measurement point and forest canopy height difference problem.When the utility model is labeled gradient data in scientific research measurement forest, can be under the situation that measurement environment changes, as requested, growing state by forest, reach the optimum efficiency of measurement environment by manual regulation lifting bar height, highly reach measurement standard with the distance that keeps measurement point and forest layer, further improve the reliability of take off data, fundamentally solved measurement point and forest canopy height difference problem;
2. simple in structure, cost is low, and is easy to operate, alerting ability is strong.
