Description

Technical Field

[0001] The utility model relates to the technical field of engineering measurement, in particular to a measuring and setting-out device used for track engineering construction. Background Art

[0002] Engineering surveying and setting-out equipment is a kind of equipment used for setting-out and measuring in construction and engineering projects. It usually consists of measuring instruments, setting-out equipment and other auxiliary tools.

[0003] When carrying out engineering design, it is necessary to use measuring equipment to survey the regional conditions. The existing Chinese patent with the authorization announcement number CN216889470U discloses an engineering measurement and setting-out device. It includes a motor, a rotating rod, a winding drum and a reciprocating screw rod. The motor drives the connected sensor rod to rotate, and the rotating winding drum retracts the measuring rope. The movement of the reciprocating screw rod reduces the probability of the measuring rope being entangled and knotted.

[0004] The laying-out equipment is used to convert the measurement data into actual lines and marks on site. It is mainly used to draw lines or set marking points on the ground to guide construction and installation. The measurement of the construction area can ensure that the building or project is constructed and installed according to the design requirements. However, when surveying the rails, it is often necessary to determine the elevation of the rail center and the rail surface. Generally, a prism is used in conjunction with a ruler. However, in the process of measuring the ruler, when the ruler angle is not placed perpendicular to the rail, the ruler will deviate from the measurement position due to the inclination of the angle. Summary of the invention

[0005] The utility model aims to solve the technical problem that in the existing device, a prism is generally used in conjunction with a ruler, but during the ruler measurement process, when the ruler angle is not placed perpendicular to the rail, the ruler causes a deviation in the measuring position due to the inclination of the angle. A measuring and laying-out device for track engineering construction is provided.

[0006] In order to solve the above technical problems, the technical solution adopted by the utility model is: a measuring and setting-out device for track engineering construction, comprising a docking component arranged on the outside of a rail body, a splicing body arranged on the top of the docking component, a survey component threadedly connected to the top of the splicing body, and a prism installed on the top of the survey component;

[0008] The cross-section of the clamping block is an inverted U-shape, and a clamping assembly is further provided inside the clamping block cavity, wherein the clamping assembly includes a guide rail fixed to the inner side of the upper portion of the clamping block, and slide grooves are respectively provided at the bottom of the upper clamping blocks located on the left and right sides of the rail body, and adjusting screws are respectively installed in the clamping block cavities located above the guide rails and corresponding to the slide grooves, the adjusting screws are arranged parallel to the guide rails, the threads of the adjusting screws on both sides are rotated in opposite directions, and the ends of the adjusting screws on both sides respectively extend out of the adjacent side walls of the clamping blocks, and side baffles are respectively threadedly connected with sleeves on the adjusting screws on both sides, and the guide rails also pass through the side baffles, the side baffles are L-shaped, and the lower ends of the side baffles extend out of the slide grooves, and the lower ends of the side baffles on both sides are arranged facing each other for clamping the rail body.

[0009] Furthermore, as a preferred solution of the engineering measurement and layout device described in the utility model, the central axis of the positioning hole and the central axis of the clamping block are on the same straight line, and when the clamping block is placed on the rail body, the central axis of the positioning hole is consistent with the central axis of the rail body.

[0011] Working process and principle: Place the card block on the top of the rail body so that the inner section of the card block contacts the top of the rail body, and rotate the corresponding adjusting screw on the guide rail so that the corresponding side baffles of the adjusting screw move along the slide groove on the guide rail due to the influence of their own threads. When the adjusting screws on both sides of the card block rotate in the same direction, the distance between the side baffles on the same guide rail gradually decreases, and the position of the card block on the rail body is fixed by reducing the distance between the side baffles, thereby reducing the probability of loosening and falling off when the device is used. Put the pointed cone and the threaded column into the positioning hole so that the bottom of the pointed cone is flush with the inner section of the card block. At this time, the central axis of the pointed cone and the central axis of the rail body are on the same straight line, and the bottom height of the pointed cone is the same as the height of the rail body.

[0014] Compared with the prior art, the utility model has the following beneficial effects:

[0015] 1. By placing the pointed cone and the threaded column into the positioning hole, the bottom of the pointed cone is flush with the inner tangent surface of the block. At this time, the central axis of the pointed cone and the central axis of the rail body are on the same straight line, and the bottom height of the pointed cone is the same as the height of the rail body. The laser ranging line is emitted through the prism to obtain the center position and length elevation data of the rail body, thereby ensuring the angle when measuring the position and reducing the probability of error.

DETAILED DESCRIPTION

[0025] The present invention is further described below in conjunction with specific embodiments. Example 1

[0026] like Figure 1-4 As shown, a measuring and setting-out device for track engineering construction comprises a docking component 2 arranged on the outside of a rail body 1, a splicing body 3 is arranged on the top of the docking component 2, a survey component 4 is threadedly connected to the top of the splicing body 3, and a prism 5 is installed on the top of the survey component 4;

[0027] The docking component 2 includes a block 21, a positioning hole 22 is formed on the surface of the block 21, and the splicing body 3 includes a pointed cone 31, a threaded column 32 is fixedly installed on the top of the pointed cone 31, the pointed cone 31 is partially inserted into the bottom of the positioning hole 22, and the top of the threaded column 32 is threadedly connected to the survey component 4;

[0028] The cross section of the card block 21 is an inverted U shape, and a card assembly 23 is further provided inside the cavity of the card block 21. The card assembly 23 includes a guide rail 231 fixed to the inner side of the upper part of the card block 21. The bottom of the upper card block 21 located on the left and right sides of the rail body 1 is respectively provided with a slide groove 232. Adjustment screws 233 are also respectively installed in the cavity of the card block 21 located above the guide rail 231 and corresponding to the slide groove 232. The adjustment screws 233 are arranged parallel to the guide rail 231. The adjusting screws 233 have opposite thread rotation directions, and the ends of the adjusting screws 233 on both sides extend out of the adjacent side walls of the block 21 respectively. The adjusting screws 233 on both sides are respectively threadedly connected with side baffles 234, and the adjusting screws 233 and the side baffles 234 correspond one to one. The guide rail 231 also passes through the side baffles 234. The side baffles 234 are L-shaped, and the lower ends of the side baffles 234 extend out of the slide groove 232, and the lower ends of the side baffles 234 on both sides are arranged to face each other for clamping the rail body 1.

[0029] Furthermore, the central axis of the positioning hole 22 and the central axis of the clamping block 21 are on the same straight line. When the clamping block 21 is placed on the rail body 1, the central axis of the positioning hole 22 is consistent with the central axis of the rail body 1.

[0030] Furthermore, the cross section of the pointed cone 31 is triangular, and the bottom of the positioning hole 22 is on the same straight line as the height of the inner section of the block 21. When the pointed cone 31 is installed in the positioning hole 22, the bottom of the pointed cone 31 is just consistent with the height of the inner section of the block 21, and when the pointed cone 31 is placed in the positioning hole 22, the bottom height of the pointed cone 31 is the same as the height of the rail body. The central axis of the pointed cone is on the same straight line as the central axis of the rail body, and the bottom height of the pointed cone is the same as the height of the rail body, thereby ensuring the angle when measuring the position and reducing the probability of error.

[0031] Working process and principle: the block 21 is placed on the top of the rail body 1, so that the inner surface of the block 21 contacts the top of the rail body 1, and the corresponding adjusting screw 233 on the rotating guide rail 231 is used to make the corresponding side baffle 234 of the adjusting screw 233 move along the slide groove 232 on the guide rail 231 due to the influence of its own thread. When the adjusting screws 233 on both sides of the block 21 rotate in the same direction, the distance between the side baffles 234 on the same guide rail 231 gradually decreases, and the block 21 is moved by the reduction of the distance between the side baffles 234. The position of the device 21 on the rail body 1 is fixed to reduce the probability of loosening and falling off when the device is used, and the pointed cone 31 and the threaded column 32 are placed in the positioning hole 22 so that the bottom of the pointed cone 31 is flush with the inner tangent surface of the block 21. At this time, the central axis of the pointed cone 31 and the central axis of the rail body 1 are on the same straight line, and the bottom height of the pointed cone 31 is the same as the height of the rail body 1. The laser ranging line is emitted by the prism 5 to obtain the center position of the rail body 1 and the length elevation data, thereby ensuring the angle when measuring the position and reducing the probability of error.

This embodiment is different from the first embodiment in that: the survey component 4 includes a base 41, and the base 41 and the upper end of the threaded column 32 are adapted to each other and threadedly connected. The top of the threaded column 32 extends to the inner side of the base 41, and a base 43 is provided on the top of the base 41. The base 41 and the base 43 are movably connected by a height bolt 42; a sleeve column 44 is movably connected to the top of the base 43, and a tension bolt 45 is provided on the outer side of the sleeve column 44. One end of the tension bolt 45 extends to the inner side of the sleeve column 44. When the length of the tension bolt 45 in the sleeve column reaches the maximum value, the sleeve column is fixed to the top of the base; a protective frame 46 is fixedly installed on the other end of the sleeve column 44, and angle bolts 47 are provided on both sides of the protective frame 46. The prism 5 located on the inner side of the protective frame 46 is movably connected between the two angle bolts 47.

[0033] The base 41 and the threaded column 32 are adapted to each other, one end of the threaded column 32 extends to the inner side of the base 41, a height bolt 42 is provided on the outer side of the base 41, a base 43 is provided on the top of the base, the base 43 is movably connected to the top of the base 41 through the height bolt 42, a thread adapted to the threaded column is provided on the bottom of the base 41, one end of the height bolt 42 passes through the entire base 43, and when the rotation degree of the height bolt 42 is the same, the base and the base are arranged parallel to each other.

[0034] When the protection frame 46 rotates, the sleeve column 44 is the center of the circle, and when the prism 5 rotates, the angle bolt 47 is the center of the circle. The prism 5 can survey the center position and length elevation of the rail body by emitting a laser ranging line.

[0035] Furthermore, a plurality of height bolts 42 penetrate through the lower edge of the base 43, and thread grooves are provided on the upper surface of the base 41 corresponding to the height bolts 42, and the bottoms of the height bolts 42 are screwed into the corresponding thread grooves to achieve connection.

[0036] A support rod is sleeved inside the sleeve column 44 , and the bottom of the support rod is fixed to the base 43 . The end of the tension bolt 45 extends into the sleeve column 44 and abuts against the support rod to achieve fixation.

[0037] Or the sleeve column 44 can also be designed as a telescopic sleeve column 44.

[0038] During use, the base 41 is fixed above the block 21 by threaded connection between the thread in the base 41 and the threaded column 32, and the height bolt 42 is rotated to make the rotation degree of the height bolt 42 the same, so that the base 43 and the base 41 are always kept horizontal while adjusting the distance between the base 43 and the base 41. The tensioning bolt 45 is rotated to reduce the length of the tensioning bolt 45 in the sleeve column 44 and increase the extension length of the sleeve column 44, thereby increasing the distance between the prism 5 in the protective frame 46 and the ground, and the angle bolt 47 is rotated to make the prism 5 rotate within the limit of the protective frame 46 with the angle bolt 47 as the center, thereby realizing the adjustment of the survey range of the prism 5, so that the device can complete the survey of different types of rails.

[0039] The remaining structures are the same as those of Example 1.
