The upper portion of the heading machine support leg is provided with an upper hinge shaft hole, and the lower portion of the heading machine support leg is provided with a ground plate. The left side and the right side on the top of the ground plate are provided with upright plates which are perpendicular to the ground plate. Semi-circular lower grooves with axes on the same straight line are arranged on the upper edges of the upright plates. The upper edges of the left upright plate and the right upright plate are provided with glands which are respectively connected with the left upright plate and the right upright plate through screw rods. The glands are provided with semi-circular upper grooves which are matched with the semi-circular lower grooves on the upper edges of the left upright plate and the right upright plate. After the glands are connected with the upper edges of the upright plates through the screw rods, the upper grooves and the lower grooves are combined to form round lower hinge shaft holes. Hinge shafts are disposed in the left lower hinge shaft hole and the right lower hinge shaft hole. According to the heading machine support leg, a lower hinge shaft seat is provided with the upright plates provided with the semi-circular lower grooves and the glands provided with the semi-circular upper grooves which are matched with the semi-circular lower grooves, and after the upright plates and the glands are connected through the screw rods, the upper grooves and the lower grooves are combined to form the round lower hinge shaft holes. Therefore, when a heading machine is in use and a hydraulic cylinder sometimes needs to be dismounted for repair at the time of failure, a hinge shaft can be easily taken out of a hinge shaft hole.

In the prior art; The hinged axle bed of development machine supporting leg lower end has and arranged on left and right sides and the vertical riser in subsides floor on paste the floor; Hinged axis hole is down arranged respectively on the left and right riser, and the axis of left and right hinged axis hole down is on same straight line, and the axis of left and right hinged axis hole down is vertical with the length direction of supporting leg; The axis of left and right hinged axis hole down is parallel with the subsides floor, and left and right have jointed shaft on the hinged axis hole down.The jointed shaft of this development machine supporting leg is to be installed in the hinged axis hole relative on the riser by fit clearance; Development machine in use; Hydraulic cylinder breaks down sometimes and need disassemble repairing, when hydraulic cylinder is descended in the supporting leg dismounting, will take out jointed shaft from hinged axle bed, because an end of hydraulic cylinder is to be hinged on down in the jointed shaft; Jointed shaft is to be installed in the following hinged axis hole relative on the hinged axle bed by fit clearance, and is pretty troublesome from descending to take out jointed shaft in the hinged axis hole.
Summary of the invention
The purpose of the utility model is in order to overcome above-mentioned deficiency, proposes a kind of development machine supporting leg that jointed shaft is taken out in the hinged axis hole at an easy rate.
The utility model is realized with following method.
The development machine supporting leg is the bending arm, and the hinged axis hole of going up is arranged at the top of supporting leg, and the subsides floor is arranged at the bottom of supporting leg; Below the subsides floor lug tooth is arranged; Above the subsides floor hinged axle bed is arranged, hinged axle bed has the vertical riser of and arranged on left and right sides and subsides floor on paste the floor, and the top of left and right riser has semicircle low groove respectively; The axis of left and right low groove semicircle is on same straight line; The axis of left and right low groove semicircle is vertical with the length direction of supporting leg, and the axis of left and right low groove semicircle is parallel with the subsides floor, and the useful screw rod in the top of left and right riser is connected in the gland on the left and right riser; The semicircle upper groove that matches with the semicircle low groove of left and right riser top is arranged on the gland; After gland was connected in the top of riser with screw rod, upper and lower groove was merged into circular hinged axis hole down, and left and right have jointed shaft in the hinged axis hole down.
The following hinged axle bed of the utility model has riser with semicircle low groove and the gland with the semicircle upper groove that matches; Riser links to each other afterwards with riser and gland with screw rod, and upper and lower groove is merged into circular hinged axis hole down; Development machine in use; Hydraulic cylinder breaks down sometimes and need disassemble when repairing, and jointed shaft is taken out in hinged axis hole at an easy rate.
Below in conjunction with accompanying drawing, the utility model is done explanation further.
