The crane beam holder 4 has a first clamping plate 8, a second clamping plate 9 and a third clamping plate 10 arranged in parallel, the second clamping plate 9 and the second clamping plate 10 are the same size, and the first clamping plate 8 is slightly shorter in length. A vertical connecting plate 12 is welded lengthwise between the second clamping plate 9 and the third clamping plate 10, and the height of the vertical connecting plate 12 is greater than the thickness of the crane beam so that the crane beam can be clamped between the second clamping plate 9 and the third clamping plate 10. The first clamping plate 8 and the second clamping plate 9 are concave plates. The first clamping plate 8 and the second clamping plate 9 are respectively provided with a notch and two symmetrical openings at corresponding positions on two sides of the vertical connecting plate 12. The bolt I14 passes through the holes on the first clamping plate 8 and the second clamping plate 9 and is fastened and combined together by a nut II15 for clamping the measuring scale 3. One side of the third clamping plate 10 corresponding to the notches of the first clamping plate and the second clamping plate is provided with an opening, and a hexagonal nut I11 horizontally placed at the position of the opening is fixed by welding to allow a screw I13 with a handle, one end of which is welded with the handle, to penetrate through so as to clamp the crane beam clamp 4 on the left crane beam 1.
Fig. 4 and 5 show a top view and a side view, respectively, of the caliper. The caliper device 5 is composed of a fourth clamping plate 16 and a fifth clamping plate 17 which are identical in structure, and holes are respectively formed in the positions corresponding to the two ends of the two clamping plates. A vertically-placed nut is welded on the fifth clamping plate 17 as a connecting piece 18 for connecting a hook of the chest expander 6, although other connecting structures (such as a ring structure and the like) can be used instead of the nut. The fourth clamping plate 16 and the fifth clamping plate 17 are combined together by means of bolts II 19 through corresponding openings and fastened with nuts III 20.
Fig. 6 and 7 show a side view and a top view, respectively, of the band handbrake clamp 7. The band hand brake holder 7 is composed of a holding part made of square tube steel 22, a hand brake 21 fixed above the square tube steel 22, and the like. A U-shaped opening is cut at one end along the length of the square tube steel 22 to ensure that the height of the opening is greater than the thickness of the crane beam. The bottom surface of the opening at the lower part is provided with an opening, a screw rod II 23 with a handle and a hand brake clamp 7 penetrates through the lower part of the corresponding position of the opening through a welding fixing nut IV 24, one end of the screw rod II is welded with the handle, and the hand brake clamp 7 is clamped on the crane beam.
The present invention measures the crane beam span by combining the measuring scale 3, the crane beam holder 4, the caliper 5, the tensioner 6 and the clamp with hand brake 7.
The measuring method of the crane beam span measuring combined device is implemented by the following steps:
step 1: the measuring tape 3 is clamped between the first clamping plate 8 and the second clamping plate 9 such that the zero point of the scale of the measuring tape 3 is aligned with the bottom of the recess of the first clamping plate 8 and the second clamping plate 9. In order to prevent the measuring tape 3 from being worn, a wear-resistant member such as rubber or a belt is added to the outside of the portion of the measuring tape 3 to be clamped. The left crane beam 1 is clamped between the second clamp 9 and the third clamp 10 with the first clamp 8 and the second clamp 9 on top and the third clamp 10 on bottom, the bottom of the recess in the first and second clamps being aligned with the outermost side of the left crane beam 1. The bolt 13 with handle is screwed through the hole on the third clamping plate 10, thereby clamping the left crane beam 1.
Step 2: the fourth clamping plate 16 and the fifth clamping plate 17 are clamped on the measuring scale at the position 100mm away from the designed span of the crane beam on the inner side of the right crane beam 2, and are fastened and clamped on the measuring scale 3 by a nut III 20 after a bolt II 19 passes through a hole on the clamping plates. Because the crane beam basically cannot be larger than 10cm according to the installation error of the column axis, the position of 100mm is selected, and the caliper 5 is prevented from being clamped at the reading position to influence data reading. Of course, where ranging is enabled, selection of a position greater than 100mm is allowed.
And step 3: the clamp with the hand brake 7 is clamped on the outer side of the right crane beam 2 through the U-shaped opening, and the right crane beam 2 is clamped through the threaded rod II with the handle 23, the threaded rod II penetrates through the nut IV 24 and the opening hole and is screwed tightly. The caliper 5, the spring exerciser 6 and the hand brake holder 7 are tightened on the same line by adjusting the hand brake cable of the hand brake 21 by hooking the hook at one end of the spring exerciser 6 to the nut on the caliper 5 (the nut is used as the connecting piece 18, and other connecting structures can be adopted as the connecting piece, such as a lifting lug, a pulling ring and the like), and the other end is connected to the hand brake cable of the hand brake 21.
And 4, step 4: the hand brake 21 is pulled to apply force, and the tension data displayed by the tension device 6 is gradually increased. And when the tension data displayed by the chest expander 6 is equal to the data of the force meter corresponding to the measuring scale, stopping pulling the hand brake 21, and reading the reading on the measuring scale 3, namely the actual span value of the crane beam.
The combined device can be installed on the ground in advance before the crane beam is installed or before the crane beam is installed before acceptance check, is convenient to manufacture and simple to operate, can be repeatedly used, and can also be used together by a plurality of tools, so that the installation and acceptance check speed is accelerated. The combined device and the measuring method can be used for measuring the span of the high-altitude crane beam and can also be used for measuring the distance between parallel objects on the ground.
The foregoing is only a preferred embodiment of the present invention. Various modifications and equivalent changes may be made by those skilled in the art without departing from the spirit and scope of the present invention, and such modifications and changes are intended to be included within the scope of the present invention.
