Detailed Description

As shown in fig. 1 and 5, the simple concrete pavement slab bar planting drilling electric drill support comprises a support 1, wherein the support 1 is formed by welding long-side angle steel and short-side angle steel, and a support leg 1.1 is installed at the bottom of the support 1. The adjustable running mechanisms 2 are arranged at the front and the back of the lower end of the support 1, the adjustable running mechanisms 2 are folded upwards when rotating holes, and are unfolded downwards to be positioned when needing to run. And screw mechanism 3 is installed to support 1 upper end, and screw mechanism 3 includes the threaded rod 3.1 of rotatable installation in the middle of support 1 through the bearing assembly, and threaded rod 3.1 passes through servo motor 3.2 drive and rotates, and both ends are fixed with guide arm 3.3 about support 1. The left and right through holes of the mounting frame 4 freely penetrate through the guide rods 3.3, and the middle part of the mounting frame 4 is in threaded connection with the threaded rods 3.1. During operation, can start servo motor 3.2, servo motor 3.2 drives threaded rod 3.1 and rotates, and threaded rod 3.1 can drive mounting bracket 4 back-and-forth movement at the pivoted in-process.

As shown in fig. 2, the mounting frame 4 includes a front mounting seat 4.1 and a rear mounting seat 4.2, through holes are drilled in the left and right of the front mounting seat 4.1, threaded holes are formed in the middle of the front mounting seat, through holes are drilled in the left and right of the rear mounting seat 4.2, and rectangular through holes are formed in the middle of the rear mounting seat. The front mounting seat 4.1 and the rear mounting seat 4.2 are fixedly welded with the connecting plate 4.3. The left and right sides of the front mounting seat 4.1 and the rear mounting seat 4.2 freely penetrate through the guide rod 3.3, and the front mounting seat 4.1 is in threaded connection with the threaded rod 3.1. When the servo motor 3.2 is activated, the threaded rod 3.1 rotates and the mounting 4 moves back and forth with it.

A screw rod 4.4 is fixed on the front mounting seat 4.1 and the rear mounting seat 4.2, a pressing plate 4.5 freely penetrates through the screw rod 4.4, and the upper end of the pressing plate 4.5 is limited by a nut 4.6. The front mounting seat 4.1 and the pressing plate 4.5 are matched to fix the drill bit of the electric drill, and the rear mounting seat 4.2 and the pressing plate 4.5 at the rear end are matched to fix the holding handle of the electric drill. This ensures that the drill is securely mounted on the mounting frame 4.

As shown in fig. 3, the adjustable walking mechanism 2 includes a rotating shaft 2.1 rotatably mounted between two legs 1.1 of the support 1 through a bearing assembly, a pair of universal wheel assemblies 2.2 are mounted on the rotating shaft 2.1, a through hole 2.3 is provided at one end or two ends of the rotating shaft 2.1 along the horizontal and vertical directions, and a limiting rod 2.4 passes through a hole on the leg 1.1 and extends into the horizontal or vertical through hole 2.3 of the rotating shaft 2.1.

In fig. 3, the universal wheel assembly 2.2 is in a lifted state, when the universal wheel assembly needs to be transferred, the limiting rod 2.4 can be drawn out, the universal wheel assembly 2.2 rotates downwards 180 degrees, the universal wheel of the universal wheel assembly 2.2 is in contact with the ground, the supporting leg 1.1 is lifted off the ground, at the moment, the limiting rod 2.4 horizontally penetrates through the hole in the supporting leg 1.1 again, and the other end of the limiting rod 2.4 extends into the through hole 2.3 for limiting again.

The height of the drill bit is matched with the height of the contact surface of the new concrete and the old concrete after the drilling machine 5 is installed. Thus, the drilling can be directly carried out without adjusting the height.

The working principle and the process are as follows: the pressing plate 4.5 and the nut 4.6 are taken down in advance, the drilling machine 5 is inverted, wherein the electric drill holds the handle and is placed between the two screw rods 4.4 of the rear mounting seat 4.2 in an inverted mode and locked by the pressing plate 4.5 and the nut 4.6. An aluminum head of a machine body behind a drill rod chuck of the electric drill is inversely placed between two screw rods 4.4 of the front mounting seat 4.1 and is locked by a pressing plate 4.5 and a nut 4.6. The servo motor 3.2 is started, the drilling machine 5 is started, and the drill bit can punch along the contact surface of new and old cement concrete in the advancing process, so that the pull rod steel bar can be conveniently implanted subsequently. When the device is transferred after drilling is completed, the adjustable travelling mechanism 2 can be opened downwards to move forwards in a direct rolling manner, so that time and labor are saved.
