[0015] Compared with existing technologies, this utility model has the following beneficial effects: 1. The portable steel space frame deviation detection tool of this utility model is directly tied to the circular tube structure of the steel space frame by straps and hoops. By adjusting the angle and length of the two telescopic rods, the weight pulls the two ropes vertically downwards along the two side walls of the circular tube. The position of the centerline of the circular tube can be determined by the midpoint of the line connecting the projection points of the two weight tips on the ground. By changing the length of the telescopic rods, multiple sampling points can be determined, thereby accurately finding the actual position of the centerline of the circular tube structure and accurately measuring the structural position deviation and installation position deviation of the steel space frame.

[0016] 2. The hammer in this utility model is equipped with a laser flashlight, which can project laser light from the tip to the ground.

[0017] 3. In this utility model, the other end of the pull rope is clamped by the first clamping block and the second clamping block and can be locked in the groove for limiting. The structure is simple and easy to maintain, and the length of the pull rope can be adjusted according to actual needs.

[0018] 4. One end of the telescopic rod in this utility model is equipped with a synchronous gear. When adjusting the rotation of one telescopic rod, the other telescopic rod can also rotate synchronously and be tightened by a second locking nut. The top of one of the second locking nuts is equipped with a sleeve and a knob. In order to save measurement and adjustment time during rapid measurement, one of the second locking nuts can be locked by turning the knob. At this time, the angles of the two telescopic rods can be locked at the same time, thereby shortening the adjustment time significantly.

[0019] 5. The bottom of the connecting seat in this utility model is provided with a detachable support block. When the hoop and strap are tied to the round tubular structure, the support block can be used to support the connecting seat to stabilize the telescopic rod. Attached Figure Description

[0030] The hoop 100 has a flat strip structure with a curved middle section. Both ends of the hoop 100 have strap through holes 130. The two ends of the strap 200 pass through the strap through holes 130 and are fitted with D-ring buckles 220. A snap fastener 210 is installed in the middle of the strap 200, allowing the middle section of the strap 200 to be disconnected or joined and its length adjusted. The hoop 100 can wrap around the upper part of the cylindrical structure and can be tightened by pulling the strap 200. The snap fastener 210 is a commonly used fastener part on the strap 200; its structure is only shown in the attached drawing to identify its type. The internal details and working principle of the snap fastener 210 will not be described in detail here. It is worth noting that the snap fastener 210 is only one optimal choice among the fastener parts for the strap 200. A fixing plate 110 is fixedly connected to the outside of the hoop 100. Through holes 120 are opened on both sides of the fixing plate 110. The axis of the through holes 120 is parallel to the axis of the hoop 100 after bending. One end of the connecting seat 300 is provided with an outwardly extending first stud 310. The diameter of the first stud 310 is the same as the diameter of the through hole 120 and passes through the through hole 120. An adjusting nut 320 and a first locking nut 330 are installed on the first stud 310. The fixing plate 110 is located between the adjusting nut 320 and the first locking nut 330.

At this time, the bottom of the support block 390 abuts against the top of the cylindrical structure.

[0031] There are two telescopic rods 400. One end of each telescopic rod 400 is integrally formed or welded to the outer circumference of the synchronizing gear 410. Two second studs 340 are provided at the other end of the connecting seat 300. The axis of the second studs 340 is perpendicular to the axis of the first stud 310. A pin shaft portion 341 is provided at the root of the second studs 340, and a threaded portion 342 is provided at the end of the second studs 340. A pin hole 411 matching the pin shaft portion 341 is provided in the middle of the synchronizing gear 410. The pin hole 411 is fitted onto the pin shaft portion 341. A second locking nut 350 and a washer 360 are installed on the threaded portion 342. The washer 360 is located between the second locking nut 350 and the synchronizing gear 410. Between gears 410, two synchronous gears 410 can mesh with each other, and the other end of the telescopic rod 400 can extend and retract outward. A first clamping block 420 is provided at the other end of the telescopic rod 400. A wire groove 430 is provided at the bottom of the first clamping block 420. The direction of the wire groove 430 is perpendicular to the direction of the telescopic rod 400. A second clamping block 440 is installed at the bottom of the first clamping block 420 by locking bolts 450. The pull rope 500 is clamped in the wire groove 430. One end of the pull rope 500 extends outward from the opposite side of the two first clamping blocks 420 and is fixedly connected to the counterweight 600, so that one end of the pull rope 500 hangs down naturally. A tip 610 is provided at the center of the bottom of the counterweight 600.

[0032] In addition, a laser flashlight is installed inside the hammer 600, with the irradiation end of the laser flashlight coinciding with the tip 610 and the irradiation direction facing downward.

[0033] Additionally, a sleeve 370 is welded to the top of one of the second locking nuts 350, and a knob 380 is welded to the top of the sleeve 370.

[0034] Next, the method of using a convenient steel space frame deviation detection tool in this embodiment will be described in detail so that those skilled in the art can better understand this utility model: In use, tie the hoop 100 and strap 200 to the horizontal cylindrical structure. First, retract the telescopic rod 400 and adjust the angle between the two telescopic rods 400 so that the distance between the two ropes 500 is less than the diameter of the cylindrical structure. Lower the two weights 600 so that the two ropes 500 hang naturally and are close to the side wall of the cylindrical structure. At this time, turn on the laser flashlight and project a laser point onto the ground. Connect the two laser points with a ruler and find the midpoint. You can then visually observe the positional relationship between the midpoint and the positioning line drawn on the ground. Then, extend the telescopic rod 400 and appropriately reduce the angle between the two telescopic rods 400. Measure the second point on the same structure using the same method to fit the actual centerline position and visually detect the deflection angle and overall deviation.

[0035] In summary, the portable steel space frame deviation detection tool in this embodiment is directly tied to the circular tube structural component of the steel space frame using straps 200 and hoops 100. By adjusting the angle and length of the two telescopic rods 400, the weights 600 pull the two ropes 500 vertically downwards along the two side walls of the circular tube. The midpoint of the line connecting the projection points of the tips 610 of the two weights 600 on the ground can be used to determine the position of the centerline of the circular tube. Furthermore, by changing the length of the telescopic rods 400, multiple sampling points can be determined, thereby accurately finding the actual position of the centerline of the circular tube structural component and accurately measuring the structural and installation position deviations of the steel space frame.
