Abstract
Description
Technical Field
[0001] The utility model relates to the field of civil engineering detection, in particular to a single-rod crane beam track deviation detection device. Background Art
[0002] The crane beam is a load-bearing structure that supports the operation of the bridge crane. The track laid on the upper flange of the crane beam enables the crane to run back and forth on the crane beam. During the design and installation process of the track on the crane beam, the center of the track and the center of the crane beam web below the track need to be on the same straight line. However, the track will be offset due to the influence of construction and installation deviations and the long-term influence of the large horizontal force of the bridge crane after it is put into use. The eccentricity of the track will cause the track to gnaw, driving vibration, and generate a large bending moment outside the plane of the crane beam, thereby causing fatigue cracking of the upper flange of the crane beam. Therefore, track offset is a key inspection item in track construction and installation, daily operation and maintenance inspections, and special inspections of crane beams.
[0003] At present, steel tape measures are mainly used to measure the offset value of the track center. When using steel tape measures, it is difficult to ensure the alignment of the starting end and the relative parallelism of the distance to be measured and the tape measure, which leads to human errors in the measurement. In addition, this method also requires climbing over the guardrails of the crane beam to enter the driving area and measure at a high altitude. Not only do personnel need to wear safety protection devices to prevent falling from heights, but track stops also need to be installed on the track to prevent accidents such as crushing and casualties caused by untimely evacuation of personnel when the vehicle passes.
[0004] The method of measuring with a steel tape measure is not only less accurate, but also requires more safety protection tools and safety assistants. At the same time, due to the greater safety risks, the corresponding entry procedures and safety education processes are relatively cumbersome, and the inspection cost and inspection cycle will increase significantly. In addition, this method inevitably requires multiple people to work together. During the measurement process, due to the distance and angle of sight, there is a possibility of increasing measurement errors. Utility Model Content

[0022] In order to make the purpose, technical solution and advantages of the utility model clearer, the technical solution of the utility model will be clearly and completely described below in conjunction with the drawings in the utility model. Obviously, the described embodiments are part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.
[0023] In order to solve the above problems, it is considered to use a customized large vernier caliper to measure the track deviation. On this basis, although personnel can operate outside the guardrail to avoid entering the driving operation area, considering that it is applicable to tracks and crane beams of various sizes, not to mention the difficulty and cost of customization, the overall cross-section of the measuring ruler is large, which makes it difficult to carry during operation. At the same time, the grid space on the guardrail may not be able to support the normal passage of such a large measuring ruler. When encountering such a situation, it is inevitable that personnel will need to enter the driving operation area to perform measurement operations, which is not only time-consuming and labor-intensive, but also inconvenient to carry. In addition, this method still inevitably requires the collaborative operation of multiple people. At the same time, during the measurement process, due to the problems of line of sight distance and angle, the possibility of measurement errors will also increase. In this regard, the utility model provides a crane beam track deviation detection device that is safer, easier to operate and more accurate.
[0024] Combine the following Figure 1-Figure 3 The utility model describes a single-rod crane beam track deviation detection device. Figure 1 This is one of the structural schematic diagrams of the single-rod crane beam track deviation detection device provided by the utility model, such as Figure 1 As shown, the single-rod crane beam track deviation detection device provided by the utility model comprises:
[0025] A main ruler 4 and a secondary ruler 5, wherein the interior of the main ruler 4 is a cavity, and the secondary ruler 5 slides in and out in the cavity along one end of the main ruler 4 parallel to the main ruler 4, and a first measuring claw 6 is fixedly installed vertically downward on the other end of the main ruler 4; a scale for length measurement is provided on the upper surface of the secondary ruler 5, and a second measuring claw 7 is fixedly installed vertically downward on one end of the lower surface close to the first measuring claw 6; a long strip of sliding groove is provided at the lower part of the main ruler 4, and the second measuring claw 7 extends out of the sliding groove and slides along the sliding groove; when the secondary ruler 5 slides, the distance between the second measuring claw 7 and the first measuring claw 6 is equal to the scale value of the secondary ruler 5 just exposed from the main ruler 4.
[0026] For the convenience of description, the concept of up and down is added in the present invention. It should be noted that the up and down are relative concepts for the convenience of description in conjunction with the drawings, rather than limiting the structure, and the up and down positions may also be interchangeable.
[0027] In the present invention, the auxiliary ruler 5 is sleeved inside the main ruler 4, and the auxiliary ruler 5 can slide freely back and forth inside the main ruler 4. Figure 2 As shown, a long strip-shaped slot is provided at the lower part of the main ruler 4, and the second measuring claw 7 extends out of the slot and slides along the slot. Figure 3As shown, the first measuring claw 6 can accurately fix the starting end of the edge measurement of the upper flange 2 of the crane beam during the measurement process, and the second measuring claw 7 is used to locate the bottom edge position of the track 3. In order to facilitate the measurement personnel to read directly, the scale surface of the secondary ruler is processed with scale lines. When the secondary ruler 4 slides, the distance between the second measuring claw 7 and the first measuring claw 6 is equal to the scale value that just exposes the cavity. For example, when the measuring claws of the main ruler and the secondary ruler are in contact, the intersection line of the main ruler on the scale surface of the secondary ruler is exactly aligned with the zero scale line.
[0028] This device is used to detect the track deviation of crane beams. Its main feature is that it can be measured directly. On-site personnel can use this product to measure the track deviation outside the guardrail. There is no need for personnel to climb over the crane beam guardrail to enter the driving area to operate, and the measurement operation can even be completed with one hand.
[0029] The specific operation process is as follows: determine the position where the track deviation needs to be measured; pass one end of the main ruler 4 with the first measuring claw 6 through the gap in the guardrail grid and extend out of the edge of the crane beam upper flange 2; stretch the secondary ruler 5 sleeved in the main ruler 4 until the second measuring claw 7 of the secondary ruler is close to the bottom surface of the track 3; hook the main ruler measuring claw 6 on the edge of the crane beam upper flange 2 and fit the bottom surface of the main ruler 4 to the track surface; press the secondary ruler measuring claw 7 against the bottom edge of the track 3, adjust the main ruler surface (horizontal adjustment can be achieved through the level 9) to keep it in a horizontal state; the surveyor can directly read the scale scale Lc at the intersection of the main ruler 4 and the secondary ruler 5; calculate the offset value ΔL=Lc-(Le+L0) / 2 of the track 3 according to the plate width Le of the crane beam upper flange 2 and the bottom surface width L0 of the track 3; when ΔL=0, it means that the track has no eccentricity, when ΔL is a negative value, it means that the track is offset in the direction of the vehicle, and when ΔL is a positive value, it means that the track is offset in the direction of the vehicle.
[0030] The utility model of the crane beam track deviation detection device, through the telescopic sliding of the main scale and the auxiliary scale, combined with two measuring claws, is conducive to miniaturization of the cross-sectional dimensions of the measuring device, so that it can pass through most of the gaps in the guardrail grid, and personnel do not need to enter the vehicle operation area to operate, and the structure is simple and easy to process. In addition, the distance between the two measuring claws is equal to the scale value that just exposes the cavity, so that the reading can be directly read from the auxiliary scale to reduce the actual operation difficulty and the number of people to cooperate, and can be operated by a single person with one hand. The measuring claws are perpendicular to the main and auxiliary scales, which is convenient for close fitting to the part to be measured, thereby improving the measurement accuracy and reducing the measurement error. In summary, the device avoids the need for personnel to climb over the crane beam guardrail to enter the vehicle operation area for measurement, reduces the operational safety risk, reduces the actual operation difficulty, improves the detection efficiency, and also ensures the accuracy of the measurement.
[0031] In some embodiments, the main scale 4 and the secondary scale 5 are free and unconnected to each other.
[0032] In some embodiments, the main ruler 4 and the auxiliary ruler 5 are connected by a spring or a cylinder. On the one hand, the spring or cylinder connection during measurement facilitates the first measuring claw 6 and the second measuring claw 7 to be closely attached to the component to be measured. On the other hand, a certain clamping force is provided for the two measuring claws during the measurement process, which facilitates the measurement personnel to free one hand for recording data. On the other hand, when the measurement is completed, after the tester lets go, the auxiliary ruler 5 can quickly return to the cavity of the main ruler 4, which is convenient for storage.
[0033] In some embodiments, the main body of the main ruler 4 and the auxiliary ruler 5 are both square rods. The square rod shape referred to in the present invention is a structure with a rectangular cross section, that is, the main body of the main ruler 4 and the auxiliary ruler 5 is a structure with a rectangular cross section. Based on the square rod structure, it can firmly fit the surface of the object to be measured.
[0034] In some embodiments, the main body of the main ruler 4 and the first measuring claw 6 form an L-shaped structure, and the main body of the secondary ruler 5 and the second measuring claw 7 form an L-shaped structure.
[0035] The main ruler 4 is a square rod-shaped structure, and the first measuring claw 6 can also be a square rod-shaped structure, and the two are vertically combined and installed in an L shape. The auxiliary ruler 5 also adopts the same structure, and the main body and the second measuring claw 7 are vertically combined and installed in an L shape. Based on this structure, it is convenient for the user to hold one end of the main ruler 4 and the auxiliary ruler 5, and hook the measuring claw at the other end to fix the part to be measured, so as to combine the main ruler 4 and the auxiliary ruler 5 for measurement.
[0036] In some embodiments, a level 9 is installed on the upper surface of the main ruler 4. The level 9 facilitates the inspection personnel to keep the main ruler 4 and the auxiliary ruler 5 horizontal and vertical during the measurement process, thereby ensuring the accuracy of the measurement.
[0037] In some embodiments, the outer layer of the first measuring claw 6 is coated with insulating paint. Since a high-voltage sliding wire for supplying electricity for the crane operation is installed on the outer side of the crane beam 1, in order to prevent electric shock, the outer layer of the first measuring claw 6 is coated with insulating paint. The insulating paint avoids the risk of high-voltage electric shock that may be encountered during the measurement process, and ensures the safety of the measurement personnel.
[0038] In some embodiments, the main material of the main ruler 4 and the secondary ruler 5 includes aluminum alloy or stainless steel. In order to ensure the rigidity of the measuring device, the main body material is selected from aluminum alloy or stainless steel to avoid deformation and thus ensure measurement accuracy. Of course, the first measuring claw 6 and the second measuring claw 7 can also be made of the same material.
[0039] In some embodiments, when the distance between the first measuring claw 6 and the second measuring claw 7 is 0, the secondary ruler 7 extends out of the main ruler 6 by a preset distance. That is, when the two measuring claws are fitted together, the overall length of the secondary ruler 5 is longer than the main ruler 4, and the extended part is convenient for pulling out during measurement.
[0040] In some embodiments, the length range of the first measuring claw 6 includes 100 mm to 500 mm. The first measuring claw 6 is located in this length range, which can basically effectively cover the heights of different tracks to be measured.
[0041] In some embodiments, the length range of the main ruler and the secondary ruler includes 1 meter to 3 meters, and the range of the scale includes 0 meter to 2 meters. In some embodiments, the range of the scale includes 0 meter to 2 meters, and the measurement accuracy can be 1mm.
[0042] The device embodiments described above are merely illustrative, wherein the units described as separate components may or may not be physically separated. Some or all of the modules may be selected according to actual needs to achieve the purpose of the present embodiment. Those of ordinary skill in the art may understand and implement the present invention without creative effort.
[0043] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of the utility model, rather than to limit it. Although the utility model has been described in detail with reference to the aforementioned embodiments, those skilled in the art should understand that they can still modify the technical solutions described in the aforementioned embodiments, or make equivalent replacements for some of the technical features therein. However, these modifications or replacements do not deviate the essence of the corresponding technical solutions from the spirit and scope of the technical solutions of the various embodiments of the utility model.
