Description

Technical Field

[0001] The invention relates to the technical field of rail detection, and in particular to a rail detection construction line type detection device. Background Art

[0002] With the continuous development of my country's railway industry, the speed of trains has been greatly improved. In order to ensure the safety, stability and comfort of train operation, extremely high requirements must be placed on the linear shape of the rails during the line laying process.

[0003] A railway line is composed of several rails connected together by fasteners and switch sleepers to form a whole. In this process, some auxiliary testing equipment is needed to cooperate with on-site construction and laying, so that the rails can be laid according to the design drawings and relevant testing standards. Therefore, this kind of testing equipment requires high accuracy on the one hand and easy use and carrying on the other.

[0004] In previous actual construction, the straightness or circular arc is usually detected by pulling a wire rope. This detection method fully meets the requirements of easy use and portability. However, due to the lack of selection of appropriate reference and reliable positioning device when fixing, the positioning is not accurate enough. In addition, during outdoor construction, due to the selection of wire rope material and stretching distance, it cannot be tightened under the influence of natural wind, forming a large arc, resulting in large deviation in the detection results, affecting the quality and efficiency of railway line laying. Summary of the invention

[0005] The purpose of the present invention is to provide a rail detection construction line type detection device to solve the above-mentioned defects caused by the prior art.

[0006] A rail detection construction line type detection device comprises a clamping mechanism and a detection mechanism, wherein:

[0007] The clamping mechanism is provided with a pair of positioning blocks and clamping blocks, which are positioned on the top surface of the rail head of the rail through the positioning blocks, and clamped on the bottom surface of the rail head and the side surface of the rail waist through the clamping blocks;

[0008] The detection mechanism is provided with a pair and is correspondingly arranged on two clamping mechanisms. The detection mechanism includes a winding wheel and a measuring tape. The measuring tape is wound between the winding wheels on the two detection mechanisms. The taut measuring tape is used as a measurement reference, and the linear shape of the rail is determined based on the distance between the rail and the measuring tape.

[0009] Preferably, the clamping mechanism further includes a mounting frame, a mounting frame and a threaded rod. The mounting frame has a "冂" - shaped structure.

A pair of mounting grooves are symmetrically distributed on the upper part of the mounting frame left and right. The positioning block is connected to the lower side of the mounting frame, and a positioning groove matching the top surface of the rail head of the rail is provided on the bottom surface of the positioning block. There are a pair of clamping blocks which are symmetrically distributed left and right. The clamping block has a parallelogram structure and is connected to the end of the mounting frame through two pairs of hinge bars. The threaded rod is rotatably connected to the center of the mounting frame, and a lifting block is threadedly connected to the threaded rod. Two steel wires are symmetrically connected to the left and right sides of the lifting block. A pair of fixed pulleys I are connected to the left and right sides of the mounting frame. A pair of fixed pulleys II are symmetrically connected to the left and right sides of the positioning block. The steel wires on the same side pass through the mounting groove, the fixed pulley I and the fixed pulley II and are connected to the outside of the clamping block.

[0010] Preferably, the winding wheel is rotatably connected to the lower part of the mounting frame through a winding shaft. One end of the measuring tape is wound on the winding wheel. A pair of "Y" - shaped brake plates are symmetrically distributed on the left and right sides of the winding wheel. A pair of guide pins are vertically connected to the outside of the brake plate. The guide pins are slidably connected to the side surface of the mounting frame, and a compression spring is sleeved on the guide pins. A right - angled triangular sliding block is connected to the lower part of the inner side of the brake plate, and an "工" - shaped straight guide rail is centrally connected to the inclined surface of the sliding block. A right - angled trapezoidal pressing block is provided below the winding wheel. "T" - shaped guide grooves are symmetrically distributed on the left and right inclined surfaces of the pressing block, and the straight guide rails on the same side are slidably connected to the guide grooves. An arc - shaped pressing groove is centrally provided on the top surface of the pressing block.

[0011] Preferably, the top end of the threaded rod is coaxially connected with a handwheel I.

[0012] Preferably, both ends of the winding shaft are coaxially connected with handwheels II.

[0013] Preferably, friction rings are coaxially adhered to the left and right sides of the winding wheel, and friction strips are adhered to the upper part of the inner side of the brake plate.

[0014] Compared with the prior art, the present invention has the following advantages:

[0015] The line - type detection device in the present invention has the characteristics of convenient loading and unloading, high - efficiency detection and accurate detection. During actual detection, first, the two clamping mechanisms are respectively clamped at both ends of the rail to be measured. Then, the measuring tapes in the two detection mechanisms are in a taut state, and the distances between the measuring ropes on the two winding wheels and the top surface of the rail head of the rail are made equal.

[0027] In order to make the technical means, creative features, objectives and effects achieved by the present invention easy to understand, the present invention is further explained below in conjunction with specific implementation methods.

[0028] like Figures 1 to 7 As shown, a rail inspection construction line type detection device includes a clamping mechanism 10 and a detection mechanism 20, wherein:

[0029] The clamping mechanism 10 is provided with a pair of positioning blocks 103 and clamping blocks 104. The positioning blocks 103 are positioned on the top surface of the rail head of the rail 30, and the clamping blocks 104 are clamped on the bottom surface of the rail head and the side surface of the rail waist of the rail 30.

[0030] The detection mechanism 20 is provided with a pair and correspondingly arranged on the two clamping mechanisms 10. The detection mechanism 20 includes a winding wheel 202 and a measuring tape 203. The measuring tape 203 is wound between the winding wheels 202 on the two detection mechanisms 20. With the tightened measuring tape 203 as the measurement reference, the line type of the rail 30 is determined according to the distance between the rail 30 and the measuring tape 203.

[0031] In this embodiment, the clamping mechanism 10 further includes a mounting frame 101, a mounting frame 102 and a threaded rod 106. The mounting frame 101 has a "冂"-shaped structure. The mounting frame 102 has a "日"-shaped structure and is connected to the middle of the mounting frame 101. A pair of mounting grooves 102a are symmetrically distributed on the upper part of the mounting frame 102. The positioning block 103 is connected to the lower side of the mounting frame 102, and a positioning groove 103a matching the top surface of the rail head of the rail 30 is provided on the bottom surface of the positioning block 103. There are a pair of clamping blocks 104, which are symmetrically distributed left and right. The clamping block 104 has a parallelogram structure and is connected to the end of the mounting frame 101 through two pairs of hinge bars 105. The threaded rod 106 is rotatably connected to the center of the mounting frame 101, and a lifting block 107 is threadedly connected to the threaded rod 106. Two steel wire ropes 108 are symmetrically connected to the left and right sides of the lifting block 107. A pair of first fixed pulleys 109 are connected to the left and right sides of the mounting frame 101. A pair of second fixed pulleys 110 are symmetrically connected to the left and right sides of the positioning block 103. The steel wire ropes 108 on the same side pass through the mounting groove 102a, the first fixed pulley 109 and the second fixed pulley 110 and are connected to the outside of the clamping block 104. When clamping, the positioning block 103 is positioned on the top surface of the rail head of the rail 30, and then the threaded rod 106 is rotated clockwise to drive the lifting block 107 to move upward, and the left and right two steel wire ropes 108 are pulled upward, so that the left and right two clamping blocks 104 move toward each other, and then the left and right two clamping blocks 104 are clamped to the bottom surface of the rail head and the side surface of the rail waist of the rail 30. When unloading, the threaded rod 106 is rotated counterclockwise to drive the lifting block 107 to move downward, and the left and right two steel wire ropes 108 are released upward, so that the left and right two clamping blocks 104 move in the opposite direction, and then the left and right two clamping blocks 104 are separated from the contact with the bottom surface of the rail head and the side surface of the rail waist of the rail 30, and then the positioning block 103 is separated from the contact with the top surface of the rail head of the rail 30.

[0032] In this embodiment, the winding wheel 202 is rotatably connected to the lower part of the mounting frame 102 through the winding shaft 201, and one end of the measuring tape 203 is wound on the winding wheel 202. A pair of "Y"-shaped brake plates 206 are symmetrically distributed on the left and right sides of the winding wheel 202. A pair of guide pins 208 are vertically connected to the outer sides of the brake plates 206. The guide pins 208 are slidably connected to the side of the mounting frame 102, and a compression spring 209 is mounted on the guide pins 208. The brake plates 206 are symmetrically arranged on the left and right sides of the winding wheel 202. A right-angled triangle sliding block 210 is connected to the lower inner side of the plate 206, and an "I"-shaped straight guide rail 211 is connected in the center of the inclined surface of the sliding block 210. A right-angled trapezoidal pressing block 212 is provided below the winding wheel 202, and "T"-shaped guide rail grooves 212a are symmetrically distributed on the left and right inclined surfaces of the pressing block 212, and the straight guide rail 211 on the same side is slidably connected to the guide rail groove 212a, and an arc-shaped pressing groove 212b is provided in the center of the top surface of the pressing block 212. Pressing the pressing block 212 downward can push the left and right sliding blocks 210 to move in opposite directions, thereby driving the left and right brake plates 206 to break contact with the left and right sides of the winding wheel 202, and then rotating the winding shaft 201 to release the measuring tape 203 on the winding wheel 202 or tighten the measuring tape 203. When the pressure on the pressing block 212 is removed, under the action of the compression spring 209, the left and right sliding blocks 210 move toward each other, thereby driving the left and right brake plates 206 to clamp on the left and right sides of the winding wheel 202 to limit the winding wheel 202 from continuing to rotate.

[0033] In this embodiment, the top end of the threaded rod 106 is coaxially connected with a hand wheel 111. The hand wheel 111 is used to facilitate the rotation of the threaded rod 106.

[0034] In this embodiment, both ends of the winding shaft 201 are coaxially connected with a second hand wheel 204. The second hand wheel 204 is used to facilitate the rotation of the winding shaft 201.

[0035] In this embodiment, friction rings 205 are coaxially bonded to the left and right sides of the winding wheel 202, and friction strips 207 are bonded to the inner side of the brake plate 206. The frictional contact between the friction ring 205 and the friction strip 207 can increase the friction resistance between the winding wheel 202 and the brake plate 206.

[0036] The working principle of this rail inspection construction line detection device:

[0037] First, the two clamping mechanisms 10 are respectively clamped on the two ends of the rail 30 to be tested, and then the measuring tapes 203 in the two detection mechanisms 20 are in a taut state, and the distances between the measuring ropes 203 on the two winding wheels 202 and the top surface of the rail head of the rail 30 are made equal. Finally, the straight line is used as the measurement reference, and the distance between the measuring tape 203 and the top surface of the rail head of the rail 30 is detected with a ruler to determine the linear shape of the rail.

[0038] Therefore, the embodiments disclosed above are only illustrative in all aspects and are not exclusive. All changes within the scope of the present invention or within the scope equivalent to the present invention are included in the present invention.
