[0024] like Figures 1 to 6 As shown, this embodiment discloses a top beam installation support device, including a hydraulic support, a top supporting mechanism, and a side supporting mechanism. The hydraulic support is composed of a fixed pipe body 1 and a lifting column 2 which is sleeved in the fixed pipe body 1 and can be lifted and lowered under the action of hydraulic oil; the top supporting mechanism is connected to the lifting column 2, and the side supporting mechanism has two groups, and the two groups of side supporting mechanisms are symmetrically arranged on both sides of the top supporting mechanism;

[0025] The jacking mechanism includes a jacking sleeve 3 and a jacking member 4; the jacking sleeve 3 is in the shape of a cylindrical shell with an open bottom end, the inner diameter of the jacking sleeve 3 is adapted to the outer diameter of the top end of the lifting column 2, and the jacking sleeve 3 is sleeved on the outer side of the top end of the lifting column 2; the cross-section of the jacking member 4 is U-shaped, the jacking member 4 is horizontally arranged, and the top end of the jacking sleeve 3 is fixedly connected to the bottom end of the jacking member 4.

[0026] The top support sleeve is directly sleeved on the top of the lifting column. When different top support parts or side support parts need to be replaced, the top support sleeve can be removed and then the various parts can be replaced. The operation is simple, convenient and fast, which improves the maintenance efficiency of the entire device.

[0027] The side supporting mechanism includes an anti-roll strut 5 and a side supporting member 6. The anti-roll strut 5 is arranged in an inclined shape. The bottom end of the anti-roll strut 5 is pin-connected to the bottom end of the side wall of the top supporting sleeve 3, and the top end of the anti-roll strut 5 is pin-connected to the side supporting member 6. A telescopic component 7 is arranged between the middle part of the anti-roll strut 5 and the upper end of the side wall of the top supporting sleeve 3 and is connected through the telescopic component 7.

Under the structural design that the fourth fixing ear of the side support member is connected to the anti-roll support rod pin, when the side support member supports the arched top beam, the side support member can rotate according to the curvature of the contact surface of the arched top beam, so that the side support member can stably support the curved contact surface of the arched top beam, thereby improving the support stability of the entire device for the arched top beam.

[0032] like Figure 5As shown, when the top beam 12 of the portal structure is lifted, the telescopic assembly 7 is adjusted to control the anti-roll support rod 5 to rotate, so that the heights of the two side support members 6 and the top support member 4 are flush, and the upper end surfaces of the two side support members 6 and one top support member 4 are in contact with the horizontal lifting end surface of the top beam 12 of the portal structure, thereby ensuring the placement stability and lifting safety of the top beam 12 of the portal structure;

[0033] like Figure 6 As shown, when the arch structure top beam 13 is lifted, the telescopic assembly 7 is adjusted to control the anti-roll support rod 5 to rotate downward, so that the heights of the two side supports 6 are lower than the height of the top support member 4, and then the center position of the arch structure top beam 13 is placed on the top support member 4, and finally the telescopic assembly 7 is adjusted again to rotate the anti-roll support rod 5 upward until the upper end surface of the side support member 6 at the top of the anti-roll support rod 5 contacts the arc-shaped curved lifting end surface of the arch structure top beam 13, thereby realizing the support operation of the side support member 6 on the arch structure top beam 13, thereby ensuring the placement stability and lifting safety of the arch structure top beam 13.

[0035] The plurality of auxiliary support rods 11 are arranged corresponding to the plurality of support ears. The auxiliary support rods 11 are arranged in an inclined shape. The top ends of the auxiliary support rods 11 are connected to the support ear pins, and the bottom ends of the auxiliary support rods 11 abut against the ground.

[0036] The positioning assembly can stably place the hydraulic support in the working area and perform top beam support operations, avoiding tipping over during the hydraulic support lifting process, improving the convenience of placing the hydraulic support, and further improving the use effect of the utility model.

[0037] The utility model adopts the design of arranging a top supporting mechanism at the top of the lifting column and arranging side supporting mechanisms on both sides of the top supporting mechanism, so that when the top beam is supported, the top beam can be supported and lifted by the top supporting member and the two side supporting members at the same time, thereby achieving the installation support effect of the top beam;
