Description

Technical Field

[0001] The utility model relates to the technical field of oil cylinder fixing, in particular to a hoist oil cylinder clamp. Background Art

[0002] When overhauling the hoist oil cylinder in a non-vertical state in a basin power station, it is necessary to straighten the hoist oil cylinder for easy detection. Currently, a manual hoist is used as an adjustment tool, and a steel chain is used to tie the hoist oil cylinder. Then, manual hoists at multiple angles are used to pull the steel chain to straighten the hoist oil cylinder. Since the steel chain will slide during the straightening process of the hoist oil cylinder, it will scratch the outer wall of the hoist oil cylinder, resulting in poor safety and stability, increasing the overhaul cost of the hoist oil cylinder, prolonging the overhaul time, with complex operation and low overhaul efficiency.

Fixed plates are fixedly connected to both ends of the two arc-shaped plates. A number of connection holes are formed in the fixed plates, and the bolts are arranged in the connection holes for splicing the two arc-shaped plates into a circle. Parallel support plates are fixedly connected to the middle parts of the two arc-shaped plates, and the support plates are arranged on the outer sides of the arc-shaped plates in the arching direction. The hinge shaft is fixedly arranged between the two support plates.

[0016] The technical solutions in the present utility model will be further described below in conjunction with the drawings and embodiments.

[0017] As Figures 1-2 shown, an embodiment of the present utility model provides a fixture for a hoist cylinder, which adopts a double-lobe structure and includes two arc-shaped plates 1, a hinge shaft 2 and a plurality of bolts 3. Fixing plates 4 are fixedly connected to both ends of the two arc-shaped plates 1. A plurality of connection holes are formed in the fixing plates 4. The bolts 3 are arranged in the connection holes and are used to fit the two arc-shaped plates 1 into a circle to enclose the outer wall of the hoist cylinder. Parallel support plates 5 are fixedly connected to the middle parts of the two arc-shaped plates 1. The support plates 5 are arranged outside the arched direction of the arc-shaped plates 1. The hinge shaft 2 is fixedly arranged between the two support plates 5.

[0018] The working principle is that two arc-shaped plates 1 are used to clamp onto the outer wall of the hoist cylinder. Then, bolts 3 are passed through multiple connection holes on the fixing plates 4 to fix the two arc-shaped plates 1 on the outer wall of the hoist. Next, a hydraulic cylinder is hinged to the hinge shaft 2 in the middle of the support plate 5. The hydraulic cylinder is used to replace the manual chain hoist to straighten the hoist cylinder. The fixture will not slip during the straightening process, avoiding damage to the outer wall of the hoist cylinder. The straightening operation of the hoist cylinder is more stable and safe. The installation and disassembly of the fixture are more convenient, improving the maintenance efficiency.

[0019] More specifically, as Figures 1-2As shown, a backing plate 6 is fixedly connected to the outer wall of the arc-shaped plate 1. Threaded blind holes arranged along the axial direction are formed in the backing plate 6. A screw 7 is threadedly connected in the threaded blind hole. A friction plate 8 is sleeved on the screw 7, and the friction plate 8 is attached to the inner wall of the arc-shaped plate 1. The friction plate 8 is used to pad between the arc-shaped plate 1 and the opening and closing oil cylinder to reduce damage to the opening and closing oil cylinder and increase the fixing effect of the fixture on the opening and closing oil cylinder. The friction plate 8 can be made of plastic plate or hard rubber plate.

[0020] More specifically, as Figure 2 shown, baffles 9 vertically arranged are fixedly connected to both sides of the backing plate 6. The baffles 9 are used to prevent the screws 7 on the backing plate 6 from being knocked off.

[0021] More specifically, as Figure 2 shown, reinforcing plates 10 perpendicular to the axial direction of the arc-shaped plate 1 are fixedly connected between the fixing plate 4 and the arc-shaped plate 1, and between the support plate 5 and the arc-shaped plate 1. The support plate 5 and the reinforcing plates 10 are fixed by welding to increase the strength of the fixing plate 4 and the support plate 5 on the arc-shaped plate 1.

[0022] More specifically, the arc-shaped plate 1 and the fixing plate 4 are integrally formed of steel plate to increase the strength of the arc-shaped plate 1 and the fixing plate 4.

[0023] More specifically, as Figure 2 shown, a limiting plate 11 perpendicular to the axial direction of the arc-shaped plate 1 is fixedly connected between the support plates 5. The limiting plate 11 is arranged on the upper and lower end faces of the support plates 5. The limiting plate 11 can be used to limit the angle of the hydraulic cylinder hinged on the hinge shaft 2 to prevent the hydraulic cylinder from deviating too much and affecting the use of the fixture. At the same time, the limiting plate 11 can also increase the structural strength of the support plates 5.

[0024] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of the present invention rather than to limit them. Although the present invention has been described in detail with reference to the preferred embodiments, those of ordinary skill in the art should understand that the technical solutions of the present invention can be modified or equivalently replaced without departing from the spirit and scope of the technical solutions of the present invention, and they should all be covered by the scope of the claims of the present invention.
