Embodiment 1

[0018] see figure 1 As shown, the door machine locking type anti-skid shoes include an anti-skid shoe device, a moving device and a self-locking device. The anti-skid shoe device includes a steel rail 12 and a locking steel plate 5. The moving device includes a screw rod 8, and a positioning nut 6 is set in the middle of the screw rod 8. And the middle part of the screw rod 8 is connected with a fixed nut 1 near the side of the positioning nut 6, and the side of the outer part of the screw rod 8 near the fixed nut 1 is covered with a spring 2, and one end of the screw rod 8 is connected with a loosening baffle 9, and one end of the screw rod 8 is welded through the loosening baffle 9. There is a fixed baffle 10, and a cylindrical head 13 is welded on one side of the fixed baffle 10, and a clamping baffle 11 is connected inside the loosening baffle 9. The self-locking device includes two connecting plates 3, and both sides of the rail 12 are connected with The connecting plate ...

Embodiment 2

[0020] Additionally, according to figure 1 As shown, the difference between it and the above-mentioned embodiment is that the other end of the screw rod 8 is connected with a handwheel 7, and turning the handwheel 7 during work can drive the screw rod 8 to rotate, increasing the torque of the screw rod 8, making it easier to rotate the screw rod 8, and the rotation is more labor-saving. The connecting plate 3 bottoms are all connected to the rail 12 sides by bolts, and the connecting plate 3 is installed and fixed more stably, and it is more convenient to move during work. The outside of the locking steel plate 5 is set in a quarter arc shape, so that its outside can be fixedly engaged with the traveling wheels 4, and the wheels are more stable when locked. The cylindrical head 13 and the fixed baffle 10 are all arranged between the clamping baffle 11 and the loosening baffle 9. When the screw rod 8 is loosened, the fixed baffle 10 can pull out the loosening baffle 9 and the l...

Abstract

The invention discloses a locking type antiskid shoe of a portal crane. The locking type antiskid shoe comprises a fixing nut, a spring, connecting plates, a walking wheel, a locking steel plate, a locating nut, a hand wheel, a screw rod, a loosening baffle, a fixed baffle, a clamping baffle, a steel rail and a cylinder head. The antiskid shoe has the beneficial effects that the locking type antiskid shoe device of the portal crane is fixed to an equilibrium bogie, the trouble of demounting is saved, and the antiskid shoe is simple, easy to understand and convenient to operate; and the portable crane is good in antiskid effect, and the wind preventing and typhoon preventing requirement of the portal crane is met. Pure mechanical design is adopted, and the situation that electrical equipment is damaged to cause failing of the device is avoided. The antiskid shoe is used during equipment locating, the device abrasion phenomenon is avoided, and the antiskid shoe is safe, stable and convenient to use. Whether the nut at the joint is loose or not and is abraded or not should be checked at ordinary times. High-strength bolt connection is adopted in all the connecting manners, a self-locking nut must be adopted for fastening, and the part loosening phenomenon caused by vibration is avoided in the work process of the device; and the antiskid shoe is high in safety performance and longin service life.

Description

technical field [0001] The invention relates to a protective shoe, in particular to door machine locking anti-skid shoes, belonging to the field of door machine application. Background technique [0002] The braking performance of the traveling mechanism of the door crane under the jurisdiction of the Bulk Cargo Operation Department is poor. During the moving or use of the door crane, there are often phenomena such as lack of anti-skid shoes, deformation and damage, etc., and the original anti-skid shoes of the door machine are not made to standard, and the door is not completely plugged. The traveling wheel of the door crane shakes a lot during the operation, which leads to the increase of the gap between the traveling wheels of the door crane. In addition, during the anti-gust process of the door machine, there is a sliding phenomenon, which poses a serious safety hazard and fails to meet the requirements for wind and typhoon protection of the equipment. Contents of the ...
