[0017] The technical scheme in the embodiments of the utility model is described clearly and completely in conjunction with the drawings, and obviously, the described embodiments are only part of the embodiments of the utility model, not all.

[0018] Embodiment 1

[0019] As Figure 1 The utility model discloses constitute parts few, simple structure, easy processing, the distance of connecting piece and base is adjusted through screw rod and rotating nut, is applicable to the fault maintenance of vertical installation big stroke heavy load electric cylinder, convenient operation, the stroke of trouble is in 400mm~3040mm range all can use, and the scope of application is wide, through the utility model support big stroke heavy load electric cylinder, avoid its falling in the maintenance process, improve the safety of maintenance process.

[0020] Embodiment 2

[0021] As Figure 2As shown, the utility model includes a connector 1, a base 5, and two sets of symmetrically arranged support and adjustment assemblies 2. Each set of support and adjustment assemblies 3 includes two screws 3 (upper screw 31, lower screw 32) and a rotating nut 4. The two screws 3 are left-handed and right-handed respectively. The connector 1 is composed of two symmetrical parts, each of which is provided with a hole corresponding to the electric cylinder push rod. The two parts can be fastened to the push rod of the electric cylinder by bolts. The connector 1 is fixedly connected to the upper screw 31, the lower screw 32, and the base 5. The upper screw 31 and the lower screw 32 are connected by the rotating nut 4. By rotating the rotating nut 4, the connection length of the rotating nut 4 with the upper screw 31 and the lower screw 32 is changed at the same time, thereby realizing rapid adjustment of the distance between the connector 1 and the base 5. It is suitable for electric cylinder push rods with a stroke of 600 to 940 mm when a fault occurs.

[0022] Example 3

[0023] like Figure 3 As shown, the structure of Example 3 differs from Example 2 only in that the lower end of the lower screw rod 32 is fixedly connected to the base 5 via the supporting square steel 6. The supporting square steel 6, as a component of the support adjustment assembly 2, uses standard square steel components, which not only increases the adjustment height of the utility model but also saves costs. It is suitable for electric cylinder push rod strokes of 900 to 1240 mm in the event of a fault.

[0024] Example 4

[0025] like Figure 4 As shown, the difference between the structure of Example 4 and Example 3 is that a reinforcement member 7 is horizontally installed on the supporting square steel 6 to increase the supporting strength of the utility model, and is suitable for electric cylinder push rod strokes of 1200 to 2140 mm when a fault occurs.

[0026] Example 5

[0027] like Figure 5 As shown, the structure of Example 5 differs from Example 4 only in that an extension 8 of the supporting square steel 6 is connected to the bottom of the supporting square steel, and is fixedly connected to the base 5 at the lower end of the extension 8. The extension 8 and the supporting square steel 6 have the same specifications, which further increases the support height of the utility model and is suitable for electric cylinder push rod strokes of 2100 to 3040 mm in the event of a fault. After removing the extension 8 and reinforcement 7, this structure becomes Example 3.

[0028] The fixing connection mode between the novel parts all adopts flange connection, and then is fixed with bolts through the same plug-in structure. It is easy to assemble and disassemble, and the necessary parts can be combined according to the fault situation, with good compatibility.

[0029] In use, according to the extension length of the electric cylinder push rod in the fault, the structure of the application is selected, the base 5 is placed, the length of the upper screw rod 31 or the upper screw rod 31 and the lower screw rod 32 extending the rotating nut 4 is adjusted until the top end of the connecting piece 1 is in contact with the lower end surface of the cylinder barrel of the electric cylinder, the connecting bolt of the two parts of the connecting piece 1 is fixed, the electric cylinder push rod is clamped by the connecting piece 1, and the supporting process is completed.
