Described rail hold-down mechanism is made up of the support rim be fixedly connected in described support plate, the U-shaped sliding sleeve being threaded bar and top board, U-shaped sliding sleeve is set on support rim and also can moves back and forth along the direction of support rim, threaded rod is fixedly connected with in the upper end of U-shaped sliding sleeve, the middle part of top board is provided with screwed hole and is connected on threaded rod by the screwed hole on it, under the state of borehole drill construction work, the end, two ends of top board is pressed on the rail that is positioned on two side positioning mechanisms, and has nut to be fixed by top board.
Further optimization, the end, two ends of described top board is provided with unworn liner.
Further optimization, the shape of the cross section of described support rim is T-shaped.
Further optimization, has gap between described location-plate and gripper shoe, and the vertical section of this T-shaped supporting pad is arranged in the gap of location-plate and gripper shoe, and the horizontal segment of T-shaped supporting pad is placed on the upper surface of location-plate and gripper shoe.
The invention has the beneficial effects as follows:
One, this device are by being arranged in the walking mechanism with detent mechanism and hold-down mechanism by rail, be on walking dolly, and be convenient to the larger rail of mobile weight, location and compress efficiency high, carry out the drilling of the rail in being moved by walking mechanism, production efficiency improves greatly.
Two, this device is provided with the walking mechanism of a band support plate, rail hold-down mechanism and the detent mechanism for locating placement rail being symmetricly set on rail hold-down mechanism both sides is fixed with in the upper surface of support plate, because walking dolly often moves once, can hole to two groups of rail, enhance productivity more than 50%.
Three, owing to being provided with T-shaped supporting pad in detent mechanism between location-plate and gripper shoe, the lower end of T-shaped supporting pad is placed in described chute also can take out; This structure has two benefits: one: can change different supporting pads to realize processing the rail of different model, improve the practicality of this device; Two, because the minor face of rail during boring impacts larger to whole supporting mechanism, therefore to support platform serious wear, and after arranging T-shaped supporting pad, vibratory impulse is transferred in location-plate and gripper shoe by this supporting pad, improve the service life of this device greatly.
