Description

Technical Field

[0001] The utility model relates to the field of civil engineering detection, in particular to a 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 measurement method using a steel tape measure not only has low accuracy, 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 be greatly increased.

[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] Prior to this, in order to solve the problem of needing to climb over the guardrail of the crane beam to enter the driving operation area for measurement, it was 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 the suitability for various sizes of tracks and crane beams, 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 this regard, the present invention provides a more convenient and safe crane beam track deviation detection device.

[0024] Combine the following Figure 1-Figure 3 The utility model describes a crane beam track deviation detection device. Figure 1 It is a structural schematic diagram of the crane beam track deviation detection device provided by the utility model, such as Figure 1 As shown, the crane beam track deviation detection device provided by the utility model includes:

[0025] The main ruler 4 and the auxiliary ruler 5 are split structures, and the main bodies are both square rods; the upper surface of the main ruler 4 is provided with a scale 10 for length measurement, and a first measuring claw 6 is vertically fixedly installed at one end downward, and the inner surface of the first measuring claw 6 is flush with the zero scale line of the scale; the auxiliary ruler 5 has a second measuring claw 7 vertically fixedly installed at one end downward, and an auxiliary positioning plate 9 is vertically fixedly installed at the same end upward, and the outer surface of the second measuring claw 7 is flush with the outer surface of the auxiliary positioning plate 9, and both are perpendicular to the main body of the auxiliary ruler 5.

[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. The up and down positions can also be interchanged. In addition, the inner surface and outer surface of the measuring claw mentioned are relative to the user. When the user holds the other end of the main ruler or the auxiliary ruler, the measuring claw facing the gripping part is the inner surface, and the outer surface away from the gripping part is the outer surface.

[0027] The first measuring claw 6 is used to locate the position of the upper flange 2 of the crane beam, and the second measuring claw 7 is used to locate the bottom edge position of the track 3. In order to facilitate positioning and reading of the scale of the main scale 4, the auxiliary positioning plate 9 is designed to have a vertical surface and an outer surface of the second measuring claw 7 (used to be close to the bottom edge side of the track) on the same plane and is firmly connected to the second measuring claw 7.

[0028] The device is used for detecting the offset of the crane beam track. Direct measurement can be adopted. On-site personnel can measure the offset of the track 3 with the help of the device outside the guardrail, without the need for personnel to climb over the crane beam guardrail to enter the driving operation area for operation.

[0029] The specific operation process is as follows: determine the position where the track offset needs to be measured, and pass the end of the main ruler 4 with the first measuring claw 6 through the gap in the guardrail grid and extend it out to the edge of the crane beam upper flange 2. Hook the edge of the crane beam upper flange 2 with the first measuring claw 6 of the main ruler 4 and fit the bottom surface of the main ruler 4 to the track surface. Pass the end of the secondary ruler 5 with the second measuring claw 7 through the gap in the guardrail grid and press the second measuring claw 7 against the bottom edge of the track 3. Bring the main ruler 4 and the secondary ruler 5 close together and adjust the two scale surfaces (horizontal adjustment can be achieved through the level 8) to keep them in a horizontal state. The reader reads the scale surface scale Lc on the main ruler 4 according to the auxiliary positioning plate 9 at the upper end of the measuring claw of the secondary ruler 5, and reads the scale surface scale Lc according to the width Le of the crane beam upper flange plate and the width L of the track bottom surface. 0 Calculate the track deviation value ΔL = Lc-(Le+L 0) / 2. When ΔL=0, it means the track has no eccentricity; when ΔL is a negative value, it means the track is offset in the direction of the vehicle; and when ΔL is a positive value, it means the track is offset out of the direction of the vehicle.

[0030] The utility model of the crane beam track deviation detection device can realize the miniaturization of cross-sectional dimensions through the main scale and the auxiliary scale combined with two measuring claws for measurement, which is conducive to passing through most of the gaps in the guardrail grid. Personnel do not need to enter the vehicle operation area for operation, and the structure is simple and easy to process. In addition, based on the first measuring claw and the second measuring claw perpendicular to the main body, it is conducive to achieving a close fit with the track to be measured and the upper flange of the vehicle beam at the same time, so as to ensure the accuracy of the measurement. The auxiliary positioning plate is used for reading, which can solve the problem of measurement difficulties and measurement errors caused by the measurement starting point and the end point not being in the same horizontal plane, improves the measurement accuracy, and has high measurement efficiency, convenience and safety. In summary, the device avoids personnel climbing over the crane beam guardrail to enter the vehicle operation area for measurement, reduces the operational safety risk, improves the detection efficiency, and also ensures the accuracy of the measurement.

[0031] In some embodiments, the length of the first measuring claw 6 is greater than the length of the second measuring claw 7. Since the top surface of the track 3 and the upper flange 2 of the crane beam 1 are not at the same horizontal height, the utility model adopts a design in which the length of the first measuring claw 6 is greater than the second measuring claw 7, ensuring that the edge measurement start end of the upper flange 2 is accurately fixed during the measurement process. Based on this, the length of the first measuring claw 6 is greater than the second measuring claw 7, which solves the problem of measurement difficulties and measurement errors caused by the measurement start and end points not being in the same horizontal plane, thereby improving the measurement accuracy.

[0032] In some embodiments, the main ruler 4 and the auxiliary ruler 5 are both square rods, the main ruler 4 and the first measuring claw 6 form an L-shaped structure, and the auxiliary ruler 5 and the second measuring claw 7 form an L-shaped structure.

[0033] 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. Figure 2 and Figure 3 As shown, 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 together to form an L-shaped installation. The auxiliary ruler 5 also adopts the same structure, and the main body and the second measuring claw 7 are vertically combined together to form an L-shaped installation. 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.

[0034] In some embodiments, the first measuring claw 6 is a square rod with the same width as the main ruler 4, and the second measuring claw 7 is a square rod with the same width as the secondary ruler 5. Considering that the main ruler 4 and the secondary ruler 5 need to pass through obstacles such as the guardrail of the crane beam 1, the widths of the main ruler 4 and the secondary ruler 5 are consistent with their respective measuring claws, thereby avoiding problems such as being blocked when passing through obstacles.

[0035] In some embodiments, a level 8 is installed on the upper surface of the main ruler 4 and / or the secondary ruler 5. The level 8 facilitates the inspection personnel to keep the main ruler 4 and the secondary ruler 5 horizontal and vertical during the measurement process, thereby ensuring the accuracy of the measurement. Specifically, the level 8 can be installed on the main ruler 4, installed on the secondary ruler 5, or installed on both the main ruler 4 and the secondary ruler 5.

[0036] In some embodiments, the outer surface of the main scale 4 and / or the other end of the secondary scale 5 is covered with a hand-held insulating rubber sleeve 11. The insulating rubber sleeve 11 can be installed at the other end of the main scale 4 or the secondary scale 5, within the range of the operator's hand holding at the end of the main scale 4. Since a high-voltage sliding wire for supplying electricity for driving will be installed on the outside of the crane beam 1, in order to prevent electric shock, the insulating rubber sleeve 11 plays an insulating role, avoiding the risk of high-voltage electric shock that may be encountered during the measurement process, which can ensure the safety of the test personnel, and at the same time increase the anti-slip effect of the hand-held end, avoiding the risk of the device falling due to improper holding during the measurement process.

[0037] In some embodiments, the main material of the main ruler 4 and the auxiliary 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, the second measuring claw and the auxiliary positioning plate can also be made of the same material.

[0038] In some embodiments, the length range of the main ruler 4 and the secondary ruler 5 includes 1 meter-3 meters (m), that is, the overall length of the main ruler 4 and the secondary ruler 5 can be designed to be in the range of 1m-3m.

[0039] 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.

[0040] In some embodiments, the scale range includes 0 meters to 2 meters, that is, the measurement range can be set to 0-2 meters, and the measurement accuracy can be 1 mm.

[0041] 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.

[0042] 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.
