Description

Technical Field

[0001] The invention belongs to the field of verticality detection, and in particular relates to a verticality detection tool for electric power engineering construction. Background Art

[0002] In the field of power engineering construction, it is crucial to ensure the verticality of the installation of various power equipment such as transformers and power cabinets. The accuracy of verticality is directly related to the safe and stable operation of the equipment and its long-term service life. Specifically, when the verticality of power equipment such as transformers or power cabinets does not meet the standards during installation, a series of serious problems will occur. First, the verticality deviation will cause the knife switch to fail to close properly, which will significantly reduce the contact area of ​​the conductive part and increase the contact resistance. After the equipment is officially put into operation, this poor contact phenomenon will cause local overheating, which will not only accelerate the aging process of the equipment, but may also cause safety accidents such as short circuits and fires, seriously threatening the stable operation of the power system.

[0003] Secondly, unqualified verticality will also cause the center of gravity of electrical equipment to shift. In the long run, this unbalanced state may lead to uneven stress distribution of the equipment structure, and in extreme cases, even cause the equipment to collapse, posing a great safety hazard to the surrounding environment and personnel. Therefore, during the installation of power equipment, accurate verticality testing of key components such as foundations and columns is an indispensable part of ensuring safe and efficient operation of the equipment.

[0004] However, the verticality detection method commonly used in the current power system is still relatively traditional, mainly relying on the combination of plumb line and steel ruler. Although this method is simple in principle, it has many shortcomings in actual operation. On the one hand, the plumb line needs enough time to stabilize in order to obtain accurate measurement results. This process is time-consuming, especially when the wind is strong or the external environment is unstable. The plumb line takes longer to stabilize, which seriously affects the construction efficiency. On the other hand, the plumb line method is easily affected by natural factors such as wind, resulting in limited measurement accuracy. It often requires multiple measurements and complex data calculations to reduce errors, which not only increases the workload, but also reduces the accuracy and reliability of the measurement. Summary of the invention

[0005] The purpose of the present invention is to overcome the deficiencies in the prior art and provide a verticality detection tool for power engineering construction to overcome the limitations of traditional detection methods, improve the efficiency of verticality detection of power equipment foundations and columns, reduce human errors, and ensure the installation quality of power equipment.

[0009] Furthermore, a plurality of support arms are provided on both sides of the trolley, threaded legs are threadedly connected to the ends of the support arms, the support arms are hinged to the trolley, and a level is provided on the top of the power box, and the level includes two mutually perpendicular level bubbles.

[0010] Furthermore, a plurality of first guide grooves are provided on the upper part of the cart, a first slide rail is provided on the lower part of the power box, and the first slide rail is slidably installed in the first guide groove; a first hydraulic cylinder is also installed on the upper part of the cart, and a piston rod of the first hydraulic cylinder is connected to one side of the power box.

[0011] Furthermore, a counterweight box is provided on one side of the power box, the counterweight box is installed on the first slide rail, and a counterweight block is placed inside the counterweight box.

[0012] Furthermore, the counterweight box is a water tank, a sand box, a heavy hammer or a concrete block.

[0013] Furthermore, a second guide groove is provided on the mounting seat, a second slide rail is slidably connected inside the second guide groove, a rack is fixedly connected to one side of the second slide rail, one end of the extension arm is rotatably connected to a gear, and the gear is meshed with the rack; a second hydraulic cylinder is provided on the back of the mounting seat, and a piston rod of the second hydraulic cylinder is connected to the upper end of the second slide rail.

[0014] Furthermore, a mounting plate is installed on one side of the rack, and a plurality of connecting rods are hinged on one side of the mounting plate, and the plurality of connecting rods are arranged parallel to the extension arm, and the other end of the connecting rod is hinged to the side plate, and the rack, the side plate and the plurality of connecting rods constitute a parallel connecting rod structure.

[0015] Furthermore, the extension arm and the connecting rod both adopt a hollow tubular structure, one end of the extension arm is movably connected to the first telescopic arm, one end of the connecting rod is movably connected to the second telescopic arm, and one end of the first telescopic arm and the second telescopic arm are both hinged to the side plate.

[0016] Furthermore, both ends of the center plate and the side plate are provided with a clamping seat, and the clamping seat includes a sleeve, and the sleeve is fixedly installed on the center plate or the side plate. Clamping plates are symmetrically provided on both sides of the sleeve, and the clamping plates on both sides are connected by springs. The spring is installed inside the sleeve, and the ruler is clamped between the two clamping plates.

[0017] The beneficial effects of the present invention are:

[0018] 1) The present invention provides side plates on both sides of the clamping frame so that three rulers can simultaneously and independently measure the verticality of the foundation or column of the power equipment. This multi-point measurement method not only significantly shortens the detection time of a single foundation or column wall, but also can more comprehensively evaluate the verticality of the foundation or column by comparing the readings of the three rulers, thereby improving the comprehensiveness and accuracy of the detection.

[0019] 2) A driving mechanism for driving the mounting seat to move up and down is set on the trolley. When it is necessary to detect the verticality of the equipment foundation or column wall at different heights, the motor is started, and the motor drives the screw to rotate, thereby driving the mounting seat and the clamping frame installed on one side of the mounting seat to move up or down along the portal frame, thereby realizing the measurement of the verticality of the foundation or column at different heights.

[0020] 3) Support arms and threaded legs for adjusting the level of the detection tool are set on both sides of the cart, which, together with the spirit level, provide convenience for the operator to adjust the level of the detection tool.

[0021] 4) When there is a wall skirt, skirting or other raised structure at the bottom of the equipment foundation or column wall, the piston rod of the first hydraulic cylinder extends to push the power box together with the portal frame and the clamping frame to the front of the cart. By rotating the threaded legs, the lower end surface of the power box is higher than the wall skirt, skirting and other raised structures. Through this operation, the operator can easily adjust the relative position of the detection tool and the wall to ensure the normal progress of the detection operation, thereby enhancing the adaptability and flexibility of the detection tool.

[0022] 5) A counterweight box is set on one side of the power box, and counterweight blocks are placed in the counterweight box to enhance the stability of the detection tool after it is pushed out.

[0023] 6) By setting a rack on one side of the mounting base and setting a gear meshing with the rack at one end of the extension arm, when the second hydraulic cylinder is extended or retracted, the rack is driven to move up and down, and the rack drives the gear at the end of the extension arm to rotate, thereby realizing the expansion and storage of the extension arm. This is not only convenient for the storage and transportation of the detection tools and saves space, but also can quickly adjust the distance between the three rulers according to the size of the foundation or column and the requirements of the detection points during the detection process, thereby realizing the precise adjustment of the distance between the detection points.

[0024] 7) A mounting plate is provided on one side of the rack, and a plurality of connecting rods are hinged on one side of the mounting plate, and the plurality of connecting rods are arranged parallel to the extension arm, and the other end of the connecting rod is hinged to the side plate. The rack, the side plate and the plurality of connecting rods constitute a parallel connecting rod structure, so that no matter what unfolding state the extension arm is in, the three rulers can remain parallel, thereby improving the accuracy and reliability of the detection.

[0025] 8) Both the extension arm and the connecting rod adopt a hollow tubular structure. One end of the extension arm is movably connected to the first telescopic arm, and one end of the connecting rod is movably connected to the second telescopic arm. The first telescopic arm and the second telescopic arm further widen the range of adjustment of the distance between the side plate and the center plate; in addition, in the conventional verticality detection mode, the first telescopic arm and the second telescopic arm maintain the same extension length contraction state, so that the three rulers remain parallel. In addition, when it is necessary to detect the flatness of the equipment foundation or the column wall, the connecting rod can be removed, and the length of the upper first telescopic arm and the lower first telescopic arm extending out of the extension arm can be adjusted, so that the rulers on the side plates on both sides are placed at an angle. The rulers placed at an angle on both sides cooperate with the rulers placed vertically on the center plate, and also realize the measurement of flatness, which improves the comprehensiveness of the detection.

[0026] 9) Clamp seats are provided at both ends of the center plate and the side plate, and the ruler can be detachably installed between the clamps on both sides of the sleeve, which is convenient for the quick installation and removal of the ruler. BRIEF DESCRIPTION OF THE DRAWINGS

DETAILED DESCRIPTION

[0035] The following will be combined with the attached Figure 1-Figure 7 , the technical solutions in the embodiments of the present invention are clearly and completely described. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of them. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0036] In the description of the present invention, it should be understood that the terms "longitudinal", "lateral", "up", "down", "front", "back", "left", "right", "vertical", "horizontal", "top", "bottom", "inside" and "outside" etc., indicating orientations or positional relationships, are based on the orientations or positional relationships shown in the accompanying drawings, and are only for the convenience of describing the present invention, and do not indicate or imply that the device or element referred to must have a specific orientation, be constructed and operated in a specific orientation, and therefore should not be understood as a limitation on the present invention.

[0037] like Figure 1 As shown, a verticality detection tool for power engineering construction includes a cart 1, a door frame 2 and a clamping frame 3. Figure 2 As shown, the lower part of the cart 1 is provided with casters to facilitate the movement of the detection tool; the door frame 2 is installed on the upper part of the cart 1, as shown in FIG. Figure 3 As shown, a mounting seat 25 is provided on one side of the door frame 2, and a clamping frame 3 is provided on one side of the mounting seat 25. Figure 5As shown, the clamping frame 3 includes a center plate 31, a plurality of support columns 311 are provided on one side of the center plate 31, and the support columns 311 are installed on the mounting seat 25. A plurality of extension arms 32 are provided on both sides of the center plate 31, and a side plate 34 is hinged at one end of the extension arm 32. A ruler 6 is installed on the center plate 31 and the side plates 34 on both sides.

[0038] The present invention firmly mounts the door frame 2 on the upper part of the cart 1, provides a stable support platform for the clamping frame 3, and configures a plurality of extension arms 32 on both sides of the center plate 31 of the clamping frame 3, and the ends of the extension arms 32 are connected to the side plates 34, so that three rulers (one on the center plate 31 and one on each of the side plates 34) can simultaneously and independently measure the verticality of the foundation or column wall. This multi-point measurement method not only significantly shortens the detection time of a single detection point, but also can more comprehensively evaluate the verticality status by comparing the readings of the three rulers, thereby improving the comprehensiveness and accuracy of the detection.

[0039] In addition, the traditional handheld ruler measurement method is easily affected by factors such as the operator's skill level, visual judgment and physical condition, resulting in certain errors in the measurement results. The present invention fixes the ruler 6 by the clamping frame 3, avoiding the instability and human error caused by hand-held operation, and ensuring the accuracy and consistency of the contact between the ruler and the foundation or column. At the same time, the simultaneous use of three rulers, through mutual verification, further reduces the error that may be generated by a single measurement point, and improves the accuracy and reliability of verticality detection.

[0040] like Figure 3 As shown, a power box 21 is provided on the upper part of the cart 1, a motor 22 is installed inside the power box 21, the portal frame 2 is installed on the upper part of the power box 21, a screw rod 23 is rotatably connected to the portal frame 2, the lower end of the screw rod 23 is connected to the motor 22 through a coupling, and one side of the mounting seat 25 is threadedly connected to the screw rod 23; guide rails 24 are provided on both sides of the portal frame 2, a slider is provided on one side of the mounting seat 25, and the slider is slidably mounted on the guide rails 24.

[0041] When it is necessary to detect the verticality of the foundation or column at different heights, start the motor 22, which drives the screw 23 to rotate, thereby driving the mounting seat 25 and the clamping frame 3 installed on one side of the mounting seat 25 to move upward or downward along the door frame 2, thereby realizing the measurement of the verticality at different heights.

[0042] like Figure 2As shown, a plurality of support arms 11 are provided on both sides of the trolley 1, and threaded legs 12 are threadedly connected to the ends of the support arms 11 for adjusting the horizontality of the detection tool. The support arms 11 are hinged to the trolley 1 for easy storage of the detection tool after use. A spirit level 29 is provided on the upper part of the power box 21, and the spirit level 29 includes two mutually perpendicular level bubbles, which can intuitively display the degree of inclination of the detection tool in the horizontal and vertical directions, providing an accurate adjustment basis for the operator.

[0044] When the bottom of the foundation or column wall has a wall skirt, skirting or other protruding structures, the piston rod of the first hydraulic cylinder 14 is extended to push the power box 21 together with the door frame 2 and the clamping frame 3 toward the front of the cart 1. By rotating the threaded support leg 12, the lower end surface of the power box 21 is made higher than the protruding structures such as the wall skirt and skirting. Through this operation, the operator can easily adjust the relative position of the detection tool and the wall to ensure the normal progress of the detection operation, thereby enhancing the adaptability and flexibility of the detection tool.

[0045] like Figure 1 , Figure 7 As shown, a counterweight box 5 is provided on one side of the power box 21, and the counterweight box 5 is installed on the first slide rail 28. A counterweight block 51 is placed inside the counterweight box 5 to enhance the stability of the detection tool after it is pushed out.

[0046] The counterweight box 5 is a water tank, a sand box, a heavy hammer or a concrete block.

[0048] When the second hydraulic cylinder 27 is extended or retracted, it drives the rack 35 to move up and down, and the rack 35 drives the gear 36 at the end of the extension arm 32 to rotate, thereby realizing the expansion and storage of the extension arm 32. This not only facilitates the storage and transportation of detection tools and saves space, but also can quickly adjust the distance between the three rulers according to the size of the foundation or column and the requirements of the detection points during the detection process, thereby realizing precise adjustment of the distance between the detection points.

The rack 35, the side plate 34 and the plurality of connecting rods 39 constitute a parallel connecting rod 39 structure, so that no matter what unfolding state the extension arm 32 is in, the three rulers can remain parallel, thereby improving the accuracy and reliability of the detection.

[0051] The first telescopic arm 33 and the second telescopic arm 391 further widen the range of distance adjustment between the side plate 34 and the center plate 31; in addition, in the conventional verticality detection mode, the first telescopic arm 33 and the second telescopic arm 391 maintain the same extended length retracted state, so that the three rulers remain parallel.

[0052] When it is necessary to detect the flatness of the foundation or column wall, the connecting rod 39 can be removed, and the length of the upper first telescopic arm 33 and the lower first telescopic arm 33 extending out of the extension arm 32 can be adjusted, so that the rulers 6 on the two side plates 34 are placed at an angle. The rulers placed at an angle on both sides cooperate with the ruler placed vertically on the center plate 31, and the flatness measurement is also realized, which improves the comprehensiveness of the detection.

[0053] like Figure 5 , Figure 6 As shown, both ends of the center plate 31 and the side plate 34 are provided with a clamping seat 4, and the clamping seat 4 includes a sleeve 41, and the sleeve 41 is fixedly installed on the center plate 31 or the side plate 34.
