Description
Technical Field
[0001] This utility model relates to the technical field of on-site surveying devices for building cost estimation, and in particular to an on-site surveying device for building cost estimation. Background Technology
[0002] The basic contents of construction project surveying include engineering surveying, hydrogeological surveying, and engineering geological surveying. The surveying task is to ascertain the natural geological conditions of the construction site, such as topography, strata, soil lithology, geological structure, and hydrological conditions, and to make identification and comprehensive evaluation. This provides a scientific and reliable basis for the site selection, engineering design, and construction of the project. During construction, surveying equipment is needed to budget the cost of the construction site.
[0003] The inventors discovered during routine use of the surveying device that, when conducting surveys, the surveying instrument is usually placed directly on a support. However, if the support tilts, the surveying instrument may fall off the support, causing damage and thus affecting the survey process. Utility Model Content
[0004] The purpose of this utility model is to address the shortcomings of existing technologies by proposing a field surveying device for building cost estimation.
[0005] To achieve the above objectives, the present invention adopts the following technical solution: a site surveying device for construction cost estimation, comprising a surveying instrument, a support frame at the bottom of the surveying instrument, a support leg fixedly connected to the bottom of the support frame, a fixing device at the top of the support frame, an adjustment device inside the support leg, an operation panel on the side of the surveying instrument, the fixing device comprising a fixing frame fixedly connected to the top of the support frame, a fixing block fixedly connected to the bottom of the surveying instrument, a groove being formed on the surface of the fixing block, and a retaining ring fixedly connected inside the fixing frame.
[0006] The effect achieved by the above components is that, under the action of the retaining ring and the groove, the surveying instrument can be fixed on the surface of the bracket, thereby achieving the function of fixation. When the surveying instrument needs to be used, it is fixed on the surface of the bracket through the fixing device to conduct a survey of the construction site and then to provide a quotation.
[0007] Preferably, a magnetic plate is fixedly connected to the bottom of the fixing block, and an iron sheet is fixedly connected to the inner wall of the fixing frame.
[0008] The effect achieved by the above components is that, under the action of the magnetic plate and the iron sheet, the fixing block can be attracted to the inside of the fixing frame, thereby achieving the function of fixing.
[0009] Preferably, a locking rod is inserted into the side of the fixing frame, and one end of the locking rod is inserted into the interior of the fixing block.
[0010] The effect achieved by the above components is that, under the action of the locking rod, the fixing block is fixed inside the fixing frame, thereby achieving the function of fixing.
[0011] Preferably, a first spring is sleeved on the surface of the clamp rod, and the two ends of the first spring are respectively fixedly connected to one end of the clamp rod on the side of the fixing frame.
[0012] The aforementioned components achieve the following effects: Under the action of the first spring, the locking rod is inserted into the fixing block in a self-locking manner, thereby achieving a fixing effect. When it is necessary to survey the construction site, the bracket is supported in a suitable position, the fixing block is inserted into the fixing frame, and the surveying instrument can be fixed on the surface of the bracket under the action of the retaining ring and the groove, thereby achieving a fixing effect. Under the action of the magnetic plate and the iron sheet, the fixing block can be attracted into the fixing frame, thereby achieving a fixing effect. Under the action of the first spring, the locking rod is inserted into the fixing block in a self-locking manner, thereby achieving a fixing effect.
[0013] Preferably, the adjusting device includes a rectangular groove formed inside the support leg, a telescopic rod slidably connected inside the rectangular groove, a screw threadedly connected to the surface of the support leg, and a pressing plate rotatably connected to one end of the screw.
[0014] The effect achieved by the above components is that, under the action of the telescopic rod, the length of the support leg can be adjusted, thus making it suitable for surveying on slopes.
[0015] Preferably, a slide rod is fixedly connected to the surface of the extrusion plate, and the slide rod is slidably connected to the surface of the support leg.
[0016] The effect achieved by the above components is that, under the action of the slide bar, the extrusion plate does not rotate with the rotation of the screw when it extrudes the telescopic rod.
[0017] Preferably, a second spring is fixedly connected inside the rectangular groove, and a telescopic rod is fixedly connected to the other end of the second spring.
[0018] The effect achieved by the above components is that, under the action of the second spring, the telescopic rod can quickly extend from the inside of the rectangular slot.
[0019] Preferably, one end of the telescopic rod and one end of the support leg are respectively fixedly connected to a baffle.
[0020] The aforementioned components achieve the following effects: under the action of the baffle, the telescopic rod will not fully extend out of the rectangular slot, thus preventing the telescopic rod from slipping off. When the support leg needs to be adjusted, the screw is turned outward, causing the telescopic rod to be ejected by the second spring. Under the action of the baffle, the telescopic rod will not fully extend out of the rectangular slot, thus preventing the telescopic rod from slipping off. After it has ejected to the appropriate position, the screw is turned, causing the pressing plate to press smoothly onto the surface of the telescopic rod under the action of the sliding rod, thereby achieving the adjustment function.
[0021] Compared with the prior art, the advantages and positive effects of this utility model are as follows:
[0022] In this invention, by setting a fixing device, when it is necessary to survey a building site, the bracket is supported in a suitable position, and the fixing block is inserted into the inside of the fixing frame. Under the action of the retaining ring and the groove, the surveying instrument can be fixed on the surface of the bracket, thereby achieving the fixing function. Under the action of the magnetic plate and the iron sheet, the fixing block can be attracted into the inside of the fixing frame, thereby achieving the fixing function. Under the action of the first spring, the locking rod is inserted into the inside of the fixing block in a self-locking manner, thereby achieving the fixing function. This solves the problem that the surveying instrument slips off the bracket when the bracket tilts during the survey. Attached Figure Description

When the surveying instrument 1 needs to be used, it is fixed to the surface of the bracket 4 through the fixing device 2 to conduct a survey of the construction site and then to provide a quote. A magnetic plate 25 is fixedly connected to the bottom of the fixing block 21. An iron sheet is fixedly connected to the inner wall of the fixing frame 22. Under the action of the magnetic plate 25 and the iron sheet, the fixing block 21 can be attracted to the inside of the fixing frame 22, thus achieving the fixing function. A retaining rod 26 is inserted into the side of the fixing frame 22. One end of the retaining rod 26 is inserted into the inside of the fixing block 21. Under the action of the retaining rod 26, the fixing block... 21 is fixed inside the fixed frame 22, thus achieving the function of fixation. The surface of the clamping rod 26 is fitted with a first spring 27. The two ends of the first spring 27 are respectively fixedly connected to the side of the fixed frame 22 and one end of the clamping rod 26. Under the action of the first spring 27, the clamping rod 26 is inserted into the interior of the fixed block 21 in a self-locking manner, thus achieving the function of fixation. When it is necessary to conduct a site survey, the bracket 4 is supported in a suitable position, and the fixed block 21 is inserted into the interior of the fixed frame 22. Under the action of the retaining ring 24 and the groove 23, the surveying instrument 1 can be fixed on the surface of the bracket 4, thus achieving the function of fixation.
