Abstract
The utility model belongs to the technical field of mining survey, in particular relates to a 360-degree reflective drop hammer. The 360-degree reflective drop hammer is characterized by comprising a suspension wire rope, a drop hammer body connected to the bottom end of the suspension cotton rope and a reflective layer pasted on the external surface of the drop hammer body, wherein the reflective layer is a piece of white opaque reflective sticker. The 360-degree reflective drop hammer has the advantages of relieving shortage of mining survey crew, enabling the survey to be finished precisely, rapidly and quickly, not only enabling following works to be connected organically, but also reducing labor intensity of survey crew and ensuring personal safety.
Description
Technical field
The utility model belongs to the technical field of mine surveying, especially relates to a kind of 360 ° of reflective sash weights.
Background technology
The daily measurement operation of underground mines is affected by environment, mining technology link, manufacturing schedule, needs the task that fulfils assignment rapidly, accurately and quickly when the operation of operating area.At first determine known lead point frame station during testing, then hang sash weight at known lead point (backsight), tested point (forward sight) is measured after setting up prism leveling centering.If the down-hole control survey, tested point is tracerse point, simultaneously hangs sash weight in forward and backward viewpoint, sets up prism, measures after the leveling centering; If measure the smashed parts, hang sash weight, set up prism at backsight, forward sight is set up prism and is carried out testing.
During concrete observation, the measurement observer seeks plumb line and the prism that hangs in the observation visor, and measurement race chi personnel must play lamp at forward and backward viewpoint place and illuminate, and the observer measures a round trip after finding target, and error is changed the station testing in allowed band; If error exceeds allowed band, carry out many round trips and measure, until precision reaches standard, just can change the station, carry out successively until the measurement task is finished, so during underground survey, run the chi personnel and wear back and forth rib at front-and rear-view, the workload of running the chi personnel is large, expends time in also longer; Forward sight Environmental security coefficient is uncertain, and there is hidden danger in personal safety.
Summary of the invention
The purpose of this utility model provides a kind of 360 ° of reflective sash weights, and the daily measurement operation of underground mines is oversimplified, and saves human and material resources, guarantees the testing precision under the security measurement, improves measuring speed, ensures and drives carrying out smoothly of postorder work.
The purpose of this utility model realizes by following technical proposals:
360 ° of reflective sash weights of the present utility model is characterized in that by the messenger wire rope, the sash weight that is connected of messenger wire rope bottom therewith, and the reflector layer that sticks on this sash weight outside surface forms, and described reflector layer is the reflective paster of White-opalescent.
Described sash weight is the assembly of vertical cylindrical body and cone, and described messenger wire rope is connected with described vertical cylindrical body center, and described cone tip is the lowermost end of described sash weight.
Advantage of the present utility model:
1) the utility model need not arrange tripod and prism in forward and backward apparent place, saves the time of centering leveling, saves man-hour, has improved precision;
2) the utility model need not remove respectively to illuminate vertical line and prism for twice at forward and backward viewpoint survey crew, saves survey crew labour intensity;
3) the utility model is because reflective plumb bob is easy to find, and survey crew illuminates at the frame station and gets final product, and has improved the survey crew safety coefficient;
4) the utility model total powerstation aiming plumb bob point and the plumb bob face of cylinder only transfer the perpendicular dish of total powerstation final motion screw to get final product, and have improved measuring speed.
Description of drawings
Fig. 1 is structural representation of the present utility model.
Fig. 2 is using method schematic diagram of the present utility model.
Embodiment
Below in conjunction with description of drawings embodiment of the present utility model.
As shown in Figure 1,360 ° of reflective sash weights of the present utility model is characterized in that by messenger wire rope 1, the sash weight 2 that is connected of messenger wire rope 1 bottom therewith, and the reflector layer 3 that sticks on these sash weight 2 outside surfaces forms, and described reflector layer 3 is the reflective paster of White-opalescent.
Described sash weight is the assembly of vertical cylindrical body and cone, and described messenger wire rope is connected with described vertical cylindrical body center, and described cone tip is the lowermost end of described sash weight.
As shown in Figure 2: be to adopt the using method of 360 ° of reflective sash weights to be:
When 1) measuring, the survey station point sets up total powerstation 5, the centering leveling, and after the start, input survey station dot information, it is plumb bob radius 20mm that the prism correction is set,
2) hang respectively 360 ° of reflective sash weights at the place ahead, the rear of survey station point, it is good that the air position of these 360 ° of reflective sash weights is that total powerstation can be considered,
3) operating personnel's 4 usefulness electric torchs are sighted 360 ° of visual reflective sash weights of rear, the most advanced and sophisticated point of total powerstation 5 aiming sash weight bottoms, and the telescope height of adjusting on the total powerstation is fair mutually with the position, the face of cylinder on the sash weight, and namely checking backsight is coordinate,
4) 6 of operating personnel's 4 usefulness torch are sighted 360 ° of visual reflective plumb bobs of the place ahead, the most advanced and sophisticated point of total powerstation 5 aiming sash weight bottoms, and the telescope height of adjusting on the total powerstation is fair mutually with the position, the face of cylinder on the sash weight, can measure the tracerse point coordinate.
Claims (2)
1. 360 ° of reflective sash weights is characterized in that by the messenger wire rope, the sash weight that is connected of messenger wire rope bottom therewith, and the reflector layer that sticks on this sash weight outside surface forms, and described reflector layer is the reflective paster of White-opalescent.
2. 360 ° of reflective sash weights according to claim 1, it is characterized in that described sash weight is the assembly of vertical cylindrical body and cone, described messenger wire rope is connected with described vertical cylindrical body center, and described cone tip is the lowermost end of described sash weight.
