DETAILED DESCRIPTION

[0016] The technical solution of the present utility model is further described below in conjunction with the accompanying drawings and embodiments.

[0017] like Figure 1~2As shown, the embodiment of the utility model proposes a hoist cylinder posture adjustment device for adjusting the angle of the hoist cylinder in the vertical direction, the hoist cylinder is hingedly installed on the cylinder base 1 through the support columns on both sides of the hoist cylinder, and the setting direction of the support columns is perpendicular to the rotation direction of the hoist cylinder, including a bracket 2, a short-axis hydraulic cylinder 3, a long-axis hydraulic cylinder 4, and a clamp 5. Two hinge seats 6 are arranged on the bracket 2, and the hinge seats 6 are respectively located on both sides of the hoist cylinder. The short-axis hydraulic cylinder 3 and the long-axis hydraulic cylinder 4 are respectively hinged on the hinge seats 6, and the clamp 5 includes two arc plates 7 and a plurality of bolts 9. Both ends of the two arc plates 7 are fixedly connected with a fixing plate 10, and a plurality of connecting holes are opened on the fixing plate 10. The bolts 9 are arranged in the connecting holes, which are used to enclose the two arc plates 7 on the hoist cylinder, and the short-axis hydraulic cylinder 3 and the long-axis hydraulic cylinder 4 are respectively hinged on the outer walls of the two arc plates 7.

[0018] The working principle is to erect the bracket 2 around the cylinder base 1, use two arc plates 7 to embrace the outer wall of the hoist cylinder, use bolts 9 to fix the arc plate 7 on the hoist cylinder, and then hinge the ends of the short-axis hydraulic cylinder 3 and the long-axis hydraulic cylinder 4 on the corresponding arc plates 7, extend the short-axis hydraulic cylinder 3, shorten the long-axis hydraulic cylinder 4, and apply force to the hoist cylinder in two directions at the same time, so as to push the hoist cylinder from an inclined state to a vertical state, and then perform maintenance operations on the hoist cylinder, and use the hydraulic cylinder to push stably instead of the hand winch to straighten the hoist cylinder. The straightening operation process of the hoist cylinder is more stable and safe, and the installation and disassembly of the clamp 5 is more convenient, thereby improving the maintenance efficiency.

[0019] More specifically, Figure 1~2 As shown, the middle parts of the two arc plates 7 are fixedly connected with parallel ear plates 11, and the ear plates 11 are arranged outside the arching direction of the arc plates 7. A hinge shaft 8 is fixedly arranged between the two ear plates 11, and the ends of the short-axis hydraulic cylinder 3 and the long-axis hydraulic cylinder 4 are respectively hinged on the hinge shafts 8 of the two arc plates 7. When in use, the corresponding arc plates 7 are first installed on the ends of the short-axis hydraulic cylinder 3 and the long-axis hydraulic cylinder 4, and when fixing the hoist cylinder, bolts 9 are used for fixing, which is convenient to use.

[0020] More specifically, Figure 1 , Figure 2As shown, the short-axis hydraulic cylinder 3 and the long-axis hydraulic cylinder 4 are respectively fixedly mounted with a clamp 12, and support plates 13 are symmetrically hinged on both sides of the clamp 12. The rotation direction of the support plate 13 is consistent with the rotation direction of the short-axis hydraulic cylinder 3 and the long-axis hydraulic cylinder 4. The support plate 13 adopts a double-bending shape, and the two ends of the support plate 13 are parallel. The opening of the hinge point between the support plate 13 and the clamp 12 can be larger than the size of the shaft. The other end of the support plate 13 is hinged with a sliding seat 14, which is fixedly connected to the bracket 2. The sliding seat 14 is slidably connected to the slide groove 15, and the slide groove 15 enables the sliding seat 14 to slide in the vertical direction. When the short-axis hydraulic cylinder 3 and the long-axis hydraulic cylinder 4 push the hoist cylinder to rotate, the movement of the short-axis hydraulic cylinder 3 and the long-axis hydraulic cylinder 4 drives the movement of the support plate 13, so that the sliding seat 14 at the bottom of the support plate 13 slides adaptively in the slide groove 15 to provide lateral support for the short-axis hydraulic cylinder 3 and the long-axis hydraulic cylinder 4, thereby avoiding the sway of the short-axis hydraulic cylinder 3 and the long-axis hydraulic cylinder 4 during articulated rotation, and improving the stability and safety of the hoist cylinder adjustment.

[0021] More specifically, Figure 2 As shown, a reinforcing plate 16 perpendicular to the axial direction of the arc plate 7 is fixedly connected between the fixing plate 10 and the arc plate 7, and between the ear plate 11 and the arc plate 7. The ear plate 11 and the reinforcing plate 16 are fixed by welding to increase the strength of the fixing plate 10 and the ear plate 11 on the arc plate 7.

[0022] More specifically, the arc plate 7 and the fixing plate 10 are integrally formed of steel plates, thereby increasing the strength of the arc plate 7 and the fixing plate 10 .

[0023] More specifically, Figure 2 As shown, a triangular-shaped tie rod 17 is fixedly connected to the bracket 2, and a screw is threadedly connected to the tie rod 17, and the tie rod 17 is used to be fixedly connected to the cylinder base 1. It is used to enhance the fixing effect of the bracket 2 to prevent the bracket 2 from moving and affecting the straightening operation of the gate hoist.

[0024] Finally, it should be noted that the above embodiments are only used to illustrate the technical solution of the utility model rather than to limit it. Although the utility model has been described in detail with reference to the preferred embodiments, ordinary technicians in the field should understand that the technical solution of the utility model can be modified or replaced by equivalents without departing from the purpose and scope of the technical solution of the utility model, which should be included in the scope of the claims of the utility model.
