Abstract
The utility model relates to tunnel construction devices, in particular to an auxiliary tool for tunnel lighting construction, which solves the problem of poor line drawing quality, large error and complex operation when installation height is measured by levels and theodolites in prior art. The tool comprises a vertical aluminum alloy running ruler and a horizontal aluminum alloy running ruler. A first level ruler is fixed to the lower end of the vertical aluminum alloy running ruler. A positioning block is movably mounted on the vertical aluminum alloy running ruler via screw bolts. One end of the horizontal aluminum alloy running ruler is placed on the positioning block, while the other end thereof is fixedly equipped with a second level ruler. The tool of the present utility model has the advantages of simple structure, reasonable design, low manufacture cost, easy operation, low error and higher line drawing quality and can be widely used in tunnel lighting construction of highways and railroads.
Description
Technical field
The utility model relates to the constructing tunnel device, is specially a kind of tunnel illumination engineering construction aid.
Background technology
In railway, highway tunnel illumination construction, the setting height(from bottom) of Cable hanger and light fixture all is to be benchmark with the rail level, and is not level, along with rail level has certain gradient.Usually in construction, to use spirit-leveling instrument and transit and cooperatively interact and measure, need to calculate a plurality of absolute altitudes, the conversion instrument position of not stopping, it is second-rate not only to locate setting-out, and error is big, and complex operation, wastes time and energy instrument use cost height.
Summary of the invention
The utility model is in order to solve in the existing tunnel illuminating engineering work progress, adopt spirit-leveling instrument and transit to cooperate to come the measuring equipment setting height(from bottom), there are problems such as setting-out is of poor quality, error big, complex operation, a kind of tunnel illumination engineering construction aid is provided.
The utility model is to adopt following technical scheme to realize: tunnel illumination engineering construction aid, comprise vertical aluminium alloy guiding ruler and horizontal aluminium alloy guiding ruler, vertically aluminium alloy guiding ruler hypomere is fixed with first surveyor's staff, vertically is movably installed with positioning wedged block by bolt on the aluminium alloy guiding ruler; Horizontal aluminium alloy guiding ruler one end is placed on the positioning wedged block, is fixed with second surveyor's staff on the other end.Described aluminium alloy guiding ruler and surveyor's staff are existing known products, and its structure and principle of work are well known to those of ordinary skill in the art.
Adopt structural design of the present utility model, positioning wedged block can be up and down on vertical aluminium alloy guiding ruler, highly determine the positioning wedged block position as required, utilize first surveyor's staff on the vertical aluminium alloy guiding ruler to guarantee that it is in vertical position simultaneously, then horizontal aluminium alloy guiding ruler one end is placed on the positioning wedged block, the other end is near a side of tunnel wall, utilize second surveyor's staff on the horizontal aluminium alloy guiding ruler to guarantee that it is horizontal, so just made lengthening right angle surveyor's staff, the position that horizontal aluminium alloy guiding ruler is pressed close to tunnel wall is the setting height(from bottom) of equipment.
Compared with prior art, the utility model is simple in structure, and is reasonable in design, and cost of manufacture is low, and simple to operate, and error is little, improved the setting-out quality greatly, can be widely used in railway, the highway tunnel illumination construction.
Description of drawings
Fig. 1 is a structural representation of the present utility model;
Among the figure: the vertical aluminium alloy guiding ruler of 1-; The horizontal aluminium alloy guiding ruler of 2-; 3-first surveyor's staff; The 4-bolt; The 5-positioning wedged block; 6-second surveyor's staff; The 7-tunnel wall.
Embodiment
Tunnel illumination engineering construction aid as shown in Figure 1, comprises vertical aluminium alloy guiding ruler 1 and horizontal aluminium alloy guiding ruler 2, and vertically aluminium alloy guiding ruler 1 hypomere is fixed with first surveyor's staff 3, allows level meter in position that the eye level can observe; Vertically be movably installed with positioning wedged block 5 by bolt 4 on the aluminium alloy guiding ruler 1; Horizontal aluminium alloy guiding ruler 2 one ends are placed on the positioning wedged block 5, are fixed with second surveyor's staff 6 on the other end.
Vertical aluminium alloy guiding ruler one end is positioned over the (end that surveyor's staff is arranged on the rail level, be convenient to people's observation), utilize first fixing above the guiding ruler surveyor's staff to make it perpendicular to rail level, mark needs measuring height h on guiding ruler, positioning wedged block is adjusted to the h height, then horizontal aluminium alloy guiding ruler one end is placed on the positioning wedged block, utilize second surveyor's staff above the horizontal aluminium alloy guiding ruler, regulate horizontal aluminium alloy guiding ruler other end height up and down, it is horizontal, the position of so horizontal aluminium alloy guiding ruler on tunnel wall is exactly the measuring position, carries out mark and gets final product.
