Description

Technical Field

[0001] The invention relates to the technical field of highway construction detection, in particular to a highway construction detection method. Background Art

[0002] During highway construction, it is necessary to test the consistency and setting time of the cement to be used. Generally, a concrete testing instrument is required. During the testing process, the upper end of the lifting rod of the instrument is set smoothly. When an operation error occurs and the bolts are not tightened immediately, if the grip on the lifting rod is loosened, the lifting rod will fall directly, which may cause the test needle to directly hit the object below, causing damage to the test needle. Moreover, after the upper end of the lifting rod is set smoothly, it is not stable enough when held in the hand, and a greater grip force is required to effectively operate the lifting rod. The operation is time-consuming and labor-intensive. Patent documents have been available to improve this.

[0003] For example, Chinese patent CN220019597U, a cement setting time detection device, belongs to the technical field of cement setting time detection, includes a base, a bracket is provided on the base, and a detection seat is installed on the upper end of the bracket, a lifting rod is provided on the detection seat, and a test needle is fixed at the lower end of the lifting rod. Through the anti-skid structure, the friction between the glass plate and the glass plate can be increased during the detection, ensuring that the glass plate can be stably placed on the base, and a spring is provided in the anti-skid structure, which can sink into the threaded sleeve with the buffer plate and other structures, and will not affect the normal placement of the glass plate and other structures. The control structure is installed on the threaded joint at the upper end of the lifting rod, which is convenient for the staff to operate the lifting rod. At the same time, the control structure can also play a limiting effect. When the lifting rod is accidentally released, the lifting rod will be limited by the control structure when it descends, thereby preventing the lower end test needle from directly hitting the object below, thereby protecting the test needle.

[0004] Although the equipment in the above documents can effectively prevent the test needle from accidentally hitting an object, it still does not bring enough good improvements in actual use, such as:

[0005] During highway construction, it is usually necessary to pre-test the concrete used. The testing method is to take a sample of the concrete and place it under the test needle, then let go and use the force of the fall to allow the test needle to naturally penetrate the inside of the sample. However, this type of experiment needs to be timed and repeated many times to obtain accurate values. After each test, not only does the test needle need to be reset, but the angle of the sample also needs to be adjusted to avoid the test needle falling in the same position when puncturing from the bottom. The entire process requires manual operation by the staff, which is too cumbersome to use and requires staff to watch on one side in real time.

[0006] Therefore, cement testing equipment for highway construction that is easy to operate and efficient is now designed to solve such defects. Summary of the invention

Beneficial Effects

[0022] The present invention provides a detection method for highway construction. Compared with the existing technology, it has the following beneficial effects:

[0023] (1) The highway construction detection method combines the basic adjustment mechanism and the lifting and puncturing mechanism. The two mechanisms can be set to perform timed lifting and lowering according to the preset electric telescopic rod, and the limit distance of each lifting and lowering can be achieved by the sliding rod and the arc-shaped support block to release and dock the concave plate, so that the descending and puncturing test can be automatically and continuously carried out. After each descent and ascent, the meshing of the arc-shaped tooth plate and the gear cylinder can be used to drive the worm wheel and the sample to rotate, thereby adjusting the position of the sample to avoid puncturing at the same position, which not only ensures the accuracy of the experimental data, but also facilitates the operation.

[0024] (2) The detection method for highway construction is to connect a square frame to the bottom end of the lifting rod, and install an arc-shaped support block on the inner side of the square frame, and use it in conjunction with a pressure frame, a blocking plate and an arc-shaped support block. The arrangement of these structures can make the arc-shaped support block flip over by squeezing the arc-shaped support block and the pressure frame after the lifting rod pulls the square frame up to the limit position, so that the initial setting detection needle descends for puncture, and after the lifting rod descends, the arc-shaped support block can be flipped upward to re-support the concave plate, so as to facilitate the next detection.

[0025] (3) The highway construction detection method comprises the following steps: a storage frame is installed on the inner side of a cylindrical tube by sliding a vertical slide tube, and an arc-shaped tooth plate is used in combination with a gear tube and a worm wheel. The arrangement of these structures enables the pressure frame to press the storage frame each time the square frame descends, so that the arc-shaped tooth plate drives the gear tube to rotate when ascending, and the worm drives the worm wheel and the sample at the bottom to rotate by the transmission of a pulley, thereby adjusting the puncture position and improving the accuracy of the detection data.

[0026] (4) The inspection method for highway construction is to install a toothed ring meshing with a half-toothed rod on the surface of the cylindrical tube. The arrangement of these two structures can rotate in two directions while being pushed by the load-bearing slides on both sides, so that the final setting inspection needle and the initial setting inspection needle can actively enter the inspection position according to different inspection items, which is convenient for the staff to use.

[0027] (5) The highway construction inspection method is to arrange a pressure plate and a limit plug plate at the bottom of the load-bearing slide plate and use them in combination with a positioning slot. After the sample is placed, the limit plug plate can be pressed into the inner side of the positioning slot by the weight of the sample itself, thereby limiting the load-bearing slide plate and ensuring stability during the inspection process.

DETAILED DESCRIPTION

[0042] The technical solutions in the embodiments of the present invention will be described clearly and completely below in conjunction with the accompanying drawings in the embodiments of the present invention.

[0043] See also Figure 1-13 The present invention provides a technical solution: a detection method for highway construction, which specifically comprises the following steps:

[0044] S1. Selection and installation of initial setting and final setting samples: When in use, according to the initial setting time test and the final setting time test of the sample, the corresponding load-bearing slide 104 in the basic adjustment mechanism 1 is pushed toward the inner side of the detection groove 102, and the sample is placed on the top of the annular placement plate 107 after the pushing is completed. Specifically, according to the initial setting time test and the final setting time test of the sample, the corresponding load-bearing slide 104 in the basic adjustment mechanism 1 is pushed toward the inner side of the detection groove 102. If the initial setting time of the sample is to be tested, the left load-bearing slide 104 is pushed, and if the final setting time of the sample is to be tested, the right load-bearing slide 104 is pushed. When the load-bearing slide 104 is pushed to the middle of the inner side of the detection groove 102, the sample that has completed the curing is placed on the top of the annular placement plate 107;

[0045] S2, structural docking to fix the sample: when the load-bearing slide 104 enters the inner side of the detection groove 102, the docking block 117 docks with the concave block 116, and then the sample is placed on the top of the annular placement plate 107, and the weight is used to press down and fix the limit. Specifically, when the load-bearing slide 104 is pushed into the inner side of the detection groove 102, the docking block 117 at the bottom enters the inner side of the concave block 116 and completes the docking, and then the sample is placed on the top of the annular placement plate 107. The weight of the sample presses the annular placement plate 107, the magnetic column 106 and the bearing ring sleeve 111 to descend at the same time. The descent of the annular placement plate 107 stores the sample to the inner side of the groove. The descent of the bearing ring sleeve 111 presses the pressure plate 112 to descend and inserts the limit plug plate 113 into the inner side of the positioning slot 125. At this time, the entire load-bearing slide 104 is limited and fixed;

[0046] S3, needle model selection: while the load-bearing slide 104 on one side is pushed, the engagement of the half-toothed rod 119 and the toothed ring 218 in the lifting and puncturing mechanism 2 will drive the cylindrical tube 201 to rotate and rotate the corresponding final coagulation detection needle 208 or initial coagulation detection needle 209 to the front. Specifically, when performing the initial coagulation time test, the load-bearing slide 104 on the left side is pushed into the inner side of the detection groove 102. During the pushing process, the load-bearing slide 104 will use the half-toothed rod 119 to engage the toothed ring 218, thereby driving the cylindrical tube 201 to rotate ninety degrees and rotating the initial coagulation detection needle 209 to the top of the sample. In addition, the concave plate 206 is also rotated under the drive of the arc-shaped slider 205 and is still in contact with the arc-shaped support block 211. At this time, the selection of the initial coagulation detection needle 209 and the final coagulation detection needle 208 is completed, and the S4 step can be transferred at any time.

[0047] S4, press down sample test: start the electric telescopic rod 202, use the lifting rod 203 and the arc-shaped support block 211 to pull the concave plate 206, the final coagulation detection needle 208 and the initial coagulation detection needle 209 to rise, and finally unlock them through the mortgage of the arc-shaped support block 224, so that the final coagulation detection needle 208 and the initial coagulation detection needle 209 naturally descend for penetration detection. Specifically, when the test is to be carried out, start the electric telescopic rod 202, and the electric telescopic rod 202 pulls the square frame 210 up through the lifting rod 203. Since the arc-shaped support block 211 is held against the limit plate 216, the arc-shaped support block 211 is locked. The concave plate 206 cannot be turned down, so it is supported and raised together with the arc-shaped slider 205. After the concave plate 206 rises, the two right-angle rods 207 will be used to drive the final setting detection needle 208 and the initial setting detection needle 209 to rise together. After the arc-shaped support block 211 pulls the concave plate 206 to rise to a preset height, the arc-shaped stop block 224 will be inserted into the inner side of the pressure frame 217 and squeeze the pressure frame 217. After the pressure frame 217 is squeezed, the sliding action of the sliding sleeve rod 214 drives the blocking plate 216 to move backward until the blocking plate 216 and the arc-shaped support block 211 are completely The arc support block 211 loses its limit and is turned downward under the weight of the concave plate 206. The turning of the arc support block 211 causes the concave plate 206 to separate from it. After the concave plate 206 separates from the arc support block 211, it drives the final coagulation detection needle 208 and the initial coagulation detection needle 209 to fall vertically under the limit of the arc slider 205 until the initial coagulation detection needle 209 is inserted into the inner side of the sample. At this time, the inserted data is recorded and observed, and then the electric telescopic rod 202 drives the lifting rod 203 and the square frame 210 to descend to the bottom. The arc-shaped abutment block 224 falls off, and the blocking plate 216 is reset under the elastic force of the third spring 215 and limits the arc-shaped support block 211 so that it cannot flip downward, until the arc-shaped support block 211 descends and contacts the concave plate 206, is abutted by the concave plate 206 and flips upward, and as it continues to descend, the arc-shaped support block 211 is re-positioned under the concave plate 206 to support it, and the electric telescopic rod 202 rises again after descending to the bottom limit position. At this time, the arc-shaped support block 211 supports the concave plate 206 and drives the final coagulation detection needle 208 and the initial coagulation detection needle 209 to rise and reset synchronously;

[0048] S5. Sample rotation adjustment: When the electric telescopic rod 202 pulls up the concave plate 206, the final coagulation detection needle 208 and the initial coagulation detection needle 209 again, the arc-shaped tooth plate 221 is used to drive the sample to rotate and adjust the next penetration position. Specifically, when the electric telescopic rod 202 descends to the limit position, the pressure frame 217 also presses the storage frame 220 to descend in the limit position of the vertical slide cylinder 219. Since the teeth of the arc-shaped tooth plate 221 are arc-shaped, they will not mesh with the gear cylinder 126. The fifth spring 223 pushes the vertical slide cylinder 219 and the storage frame 220 to rise again. At this time, the arc-shaped toothed plate 221 protrudes under the elastic force of the fourth spring 222 and meshes with the gear cylinder 126, and drives the gear cylinder 126 to rotate during the rising process. Since there is no tooth on the upper part of the surface of the arc-shaped toothed plate 221, the initial coagulation detection needle 209 or the final coagulation detection needle 208 will be separated from the sample before falling behind. The rotation of the gear cylinder 126 will also drive the worm 121 to rotate through the transmission of the pulley 122 and the belt 123. Since the worm 121 is meshed with the worm wheel 115, the rotation of the worm 121 also drives the worm wheel 115 to rotate. Under the docking of the concave block 116 and the docking block 117, the circular bottom plate 114, the limiting cylinder 108, the bearing ring sleeve 111, the magnetic column 106, and the annular placement plate 107 are also driven to rotate. The rotation of the annular placement plate 107 drives the sample to rotate a certain distance to ensure The next time the initial coagulation detection needle 209 falls, it will not puncture at the same position. After the worm gear 115 rotates one circle to reset, the tested sample is directly picked up from the top of the annular placement plate 107. At this time, the pressure plate 112 drives the limiting plug plate 113 to rise and disengage from the positioning slot 125 under the pulling force of the first spring 127. At this time, the load-bearing slide 104 is no longer limited, and the load-bearing slide 104 is directly pushed to leave the detection groove 102. At the same time, the cylindrical tube 201 is rotated in the opposite direction by ninety degrees again under the action of the half-tooth rod 119 to reset.
