Description

TECHNICAL FIELD

[0001] The present application relates to the technical field of self-locking hydraulic bolt crane anchoring base, and particularly relates to a self-locking hydraulic bolt crane anchoring base. BACKGROUND

[0002] The core principle of the hydraulic bolt crane anchoring base is to achieve accurate anchoring of the bolt and the base through hydraulic drive. When the crane stops working, especially in windy weather, the hydraulic system will start to push the bolt into the anchoring hole on the ground or the track, thereby fixing the crane to prevent it from sliding or overturning. The structural design combines a hydraulic cylinder and an anchoring seat. The output end of the hydraulic cylinder is provided with an oil baffle cover. When the oil baffle cover moves downward, the motor covers the anchoring column, and self-lubrication is achieved by using a compression spring and lubricating oil, thereby reducing wear and tear. Reinforcing ribs are arranged on both sides of the anchoring seat, and a limiting cone tip is arranged at the top of the anchoring column, which cooperates with the positioning groove of the piston to ensure the anchoring stability. This device is mainly applied to port bridges, gantry cranes and tower cranes, especially in coastal windy areas, and the anchoring force needs to be matched with the windward area and the design load of the crane. For example, the design of a single-track double-anchoring pit of a shore bridge can offset the torque, and the insertion depth of the anchoring column needs to exceed 150 mm to ensure safety.

[0003] The existing self-locking hydraulic bolt crane anchoring base sets a positioning hole at a specific point to cooperate with the bolt positioning, but the positioning position is relatively fixed, and the crane is relatively limited when moving, or the motor output shaft is fixed by the motor brake. Due to the large inertia of the cargo during the suspension process, this fixing method is easy to cause damage to the motor brake system.

The second sliding piece 14 is movably installed in the first sliding groove 13, and a pressing piece 17 is movably installed in the first sliding groove 13. A rubber pad 16 is fixedly installed on the end of the second sliding piece 14. A first inclined surface 18 is formed on the lower surface of the second sliding piece 14. A second inclined surface 19 is formed on the upper surface of the pressing piece 17. The pressing piece 17 is movably installed below the second sliding piece 14.

The second sliding groove 15 avoids the mutual interference between the second sliding piece 14 and the active column 22.

[0038] The fixing mechanism comprises a fixing piece 24 movably installed on the outer side of the first sliding piece 12, and the fixing piece 24 is movably installed on the outer side of the motor base 27.

The first sliding piece 12 is fixedly installed on the inner side of the motor base 27 through the threaded holes 25 and the screws 26. The moving wheels on the motor base 27 are clamped by the inclined surface of the inclined L-shaped plate 29, thereby preventing movement.

[0039] The elastic return mechanism comprises two spring fixing members 31 fixedly installed on the lower surface of the first sliding member 12, third springs 33 fixedly installed in the two spring fixing members 31, two inclined L-shaped plates 29 installed on the opposite surfaces of the spring fixing members 31, second convex grooves 30 respectively formed on the upper surfaces of the two inclined L-shaped plates 29, and second limiting plates 32 movably installed in each second convex groove 30 and fixedly installed on the lower surfaces of the spring fixing members 31. When the telescopic cylinder 3 is retracted backward, the abutting member 17 is reset upward, the third springs 33 in the two spring fixing members 31 drive the two inclined L-shaped plates 29 to move inward, and the inclined L-shaped plates 29 are reset. The second convex grooves 30 and the second limiting plates 32 limit the moving range of the inclined L-shaped plates 29.

[0040] Other components 36 are fixedly installed on the outer side of the motor base 27. The other components 36 of the crane are prior art, which will not be described in detail here.

[0041] In use, the fixing member 24 is placed on the outer side of the motor base 27, and the first sliding member 12 is fixed on the inner side of the motor base 27 through the threaded hole 25 and the bolt 26. When work is needed, the device is placed on the lower edge of the cross beam 35 of the support 34. When self-locking is needed, the telescopic cylinder 3 is telescoped forward, the fold-shaped guide 5 contacts the inclined plate 8, drives the inclined plate 8 to slide forward, and the inclined plate 8 drives the large L-shaped plate 9 to move inward. When the large L-shaped plate 9 moves inward, the second sliding member 14 fixedly installed on the inner side of the large L-shaped plate 9 moves inward. The first sliding groove 13 allows the second sliding member 14 to move in the first sliding member 12, so that the rubber pad 16 abuts against the surface of the I-shaped piece 1, and plays a certain braking role. At the same time, when the second sliding member 14 moves inward, the first inclined surface 18 also moves inward, the second inclined surface 19 attached to the first inclined surface 18 is stressed to drive the abutting member 17 to move downward, the abutting member 17 in the widened groove 28 is stressed to move downward, the auxiliary inclined surface 38 at the lower end of the abutting member 17 contacts the inclined surface above the two inclined L-shaped plates 29, the auxiliary inclined surface 38 separates the two inclined L-shaped plates 29 as the abutting member 17 moves downward, the main inclined surface 37 at the lower end of the abutting member 17 contacts the inclined surface above the two inclined L-shaped plates 29 as the abutting member 17 continues to move downward, the two inclined L-shaped plates 29 move outward to the outer side of the moving wheels of the motor base 27, and the moving wheels are clamped by the inclined surface below the inclined L-shaped plates 29. When the telescopic cylinder 3 is telescoped forward and backward, the first spring 7 drives the large L-shaped plate 9 to move outward, the large L-shaped plate 9 is reset, the second sliding member 14 moves outward, the second spring 23 sleeved on the outer side of the movable column 22 drives the movable column 22 to move upward and reset, thereby driving the first connecting plate 20 to move upward, the abutting member 17 is reset, and the third springs 33 in the two spring fixing members 31 drive the two inclined L-shaped plates 29 to move inward, so that the inclined L-shaped plates 29 are reset.
