As shown in fig. 1 and 2, the cross beam 1 may be a hexahedron, and two opposite sides of the hexahedron are planes, and the two opposite sides are provided with through slots 11. The crossbeam 1 comprises at least two opposite planes, can make things convenient for the fixed of clamping assembly 2, make things convenient for clamping assembly 2 and girder steel 4's fixed, make things convenient for stock coupling assembling 3 and crossbeam 1's fixed to and be favorable to crossbeam 1 self balance. Of course, the cross beam 1 may have other shapes as long as two opposite planes are maintained.

Referring to fig. 3 and 4, the clamping assembly 2 includes two sets of clamping members 21, and the clamping members 21 include a first screw 211, a first nut 212, a lower clamping plate 213, and a second nut 214.

As shown in fig. 1, when the steel beam 4 is an i-beam, the upper cross plate 41 of the i-beam 4 is a portion to be clamped, and the profile of the clamping space is matched with the profile of the upper cross plate 41, so that the two lower clamping plates 213 can clamp the upper cross plate 41. Of course, the outline of the clamping space can be changed according to actual requirements, so that the device is wider in applicability, and can be suitable for quick connection of a walking steel beam such as H-shaped steel and the like and a hole roof anchor rod 6.

When the relative position between the steel beam 4 and the beam 1 needs to be adjusted, the first nuts 212 and the second nuts 214 are loosened, so that the two lower clamping plates 213 of the two groups of clamping pieces 21 move along the length direction of the steel beam 4 at the same time to drive the two groups of clamping pieces 21 to move along the length direction of the steel beam 4 at the same time, or the first screw rods 211 of the two groups of clamping pieces 21 move in the through grooves 11 at the same time to drive the two groups of clamping pieces 21 to move along the length direction perpendicular to the steel beam 4, and after the position of the steel beam 4 relative to the beam 1 is determined, the first nuts 212 and the second nuts 214 of the two groups of clamping pieces 21 are tightened, thereby realizing the movement of the beam 1 along the length direction of the steel beam 4 in fig. 1, namely, the movement of the beam 1 along the length direction perpendicular to the steel beam 4 in the X-axis direction in fig. 1. At this time, in order to achieve both the movement of the clamping member 21 on the steel beam 4 and the fixation of the clamping member 21 to the cross beam 1, the outer diameter of the first nut 212 needs to be larger than the width of the through groove 11 (i.e., the width of the through groove 11 in the Y-axis direction).

Referring to fig. 1, two anchor rod connecting assemblies 3 are respectively disposed at two sides of a steel beam 4. Referring to fig. 5 and 6, the anchor rod connection assembly 3 includes a sleeve group 31, a second screw rod 32, a third nut 33 and a fourth nut 34.

The lower end of the second screw 32 is sleeved with a third nut 33 and then passes through the through groove 11, and is sleeved with a fourth nut 34 so as to fix the sleeve group 31 with the cross beam 1. Specifically, after the positions of the anchor rod connecting assemblies 3 and the cross beam 1, that is, the positions of the anchor rods 6 and the steel beams 4 are determined, the third nuts 33 and the fourth nuts 34 of the two sets of anchor rod connecting assemblies 3 are screwed. Of course, in practice, the position of the anchor rod connecting assembly 3 on the beam 1 may be adjusted, specifically, when the relative position of the anchor rod connecting assembly 3 and the beam 1 needs to be adjusted, the third nut 33 and the fourth nut 34 are unscrewed, the second screw 32 slides to the required position along the through groove 11, and the third nut 33 and the fourth nut 34 are screwed, so that the anchor rod connecting assembly 3 moves along the length direction perpendicular to the steel beam 4, that is, the movement along the X-axis direction of fig. 1 is realized. At this time, in order to achieve both the movement of the anchor rod connection assembly 3 in the longitudinal direction perpendicular to the steel beam 4 and the fixation of the anchor rod connection assembly 3 to the cross beam 1, the outer diameters of the third nut 33 and the fourth nut 34 need to be larger than the width of the through groove 11 (i.e., the width of the through groove 11 in the Y-axis direction).

In addition, when the relative position of the second screw rod 32 and the anchor rod 6 needs to be adjusted, after the sleeve group 31 of the anchor rod connecting assembly 3 is fixed with the anchor rod 6, the third nut 33 and the fourth nut 34 of any group of anchor rod connecting assemblies 3 are screwed in the same direction at the same time, so that the second screw rod 32 of the anchor rod connecting assembly 3 moves relatively upwards or downwards, and the horizontal adjustment of the cross beam 1 can be realized; simultaneously, the third nuts 33 and the fourth nuts 34 of the two groups of anchor rod connecting assemblies 3 are screwed in the same direction, so that the second screws 32 of the two groups of anchor rod connecting assemblies 3 move upwards or downwards by the same distance relatively, the adjustment of the ground clearance of the cross beam 1 can be realized, and the cross beam 1 is fixed with the steel beam 4 through the clamping assembly 2, so that the ground clearance of the steel beam 4 can be adjusted in a small range, and further the height use requirement of the beam crane is realized. And after the horizontal and height adjustment of the cross beam 1 is finished, the third nut 33 and the fourth nut 34 of the anchor rod connecting assembly 3 are screwed, and the anchor rod connecting assembly 3 is fastened with the cross beam 1.

The device for quickly connecting the anchor rod and the steel beam during the installation of the beam crane provided by the embodiment of the invention comprises a cross beam 1, a clamping assembly 2 and two groups of anchor rod connecting assemblies 3.

The lower end of the first screw 211 passes through the through groove 11 and the lower clamping plate 213 and is sleeved with a second nut 214, and the upper end of the first screw is sleeved with a first nut 212 so as to fix the lower clamping plate 213 with the cross beam 1. The two groups of anchor rod connecting assemblies 3 are respectively arranged on two sides of the steel beam 4. The anchor rod connection assembly 3 includes a sleeve set 31, a second threaded rod 32, a third nut 33 and a fourth nut 34. The sleeve group 31 is disposed at the upper end of the second screw 32 and has axes parallel to each other for fixing the anchor rod 6. The lower end of the second screw 32 is sleeved with a third nut 33 and then passes through the through groove 11, and is sleeved with a fourth nut 34 so as to fix the sleeve group 31 with the cross beam 1. Because the anchor rod 6 is fixed with the sleeve group 31 of the anchor rod connecting assembly 3, the anchor rod connecting assembly 3 is fixed with the cross beam 1, and the cross beam 1 is fixed with the steel beam 4 through the clamping assembly 2, thereby realizing the rapid fixation of the anchor rod 6 and the steel beam 4. When the depth and the angle of the working surface of the tunnel top of an underground facility such as a tunnel, an underground tunnel and the like are changeable, and the length, the position and the azimuth of the anchor rod 6 are greatly different from the design, as the anchor rod connecting component 3 and the clamping component 2 can move along the through groove 11 of the cross beam 1 and the clamping component 2 can move along the length direction of the steel beam 4, the position change of the anchor rod connecting component 3 and the clamping component 2 relative to the steel beam 4 is realized, the position change of the anchor rod 6 relative to the steel beam 4 is realized, the anchor rod 6 can be positioned and fixed with the steel beam 4 quickly, the installation connection of the steel beam 4 and the anchor rod 6 is time-saving and labor-saving, and the installation connection of the steel beam 4 and the anchor rod 6 is easy to realize.
