[0033] Please see Figures 1 to 8 , now a kind of temporary supporting device provided by the utility model is described.The temporary supporting device includes support cross beam 1, telescopic inner cylinder 2, fixed outer cylinder 3 and lifting driving part 4, and the bottom of support cross beam 1 is hinged to the top of telescopic inner cylinder 2;Telescopic inner cylinder 2 is arranged in the inside of fixed outer cylinder 3, and telescopic inner cylinder 2 and fixed outer cylinder 3 are slidingly matched;Lifting driving part 4 is arranged in the inside of telescopic inner cylinder 2, and the bottom end of lifting driving part 4 is connected to fixed outer cylinder 3, and the top end of lifting driving part 4 is connected to telescopic inner cylinder 2;Wherein, deflection angle limiting structure 5 is arranged between support cross beam 1 and telescopic inner cylinder 2, to limit the deflection angle of support cross beam 1 in preset range;Support cross beam 1 includes hinged plate 11 and support frame 12 connected to the both sides of hinged plate 11, and hinged plate 11 is hinged to telescopic inner cylinder 2.

[0034] Compared with the prior art, the temporary supporting device and the roof bolting machine are in the retracted state when the tunneling anchor integrated machine main machine is used for tunneling, anchor rod supporting operation is carried out after tunneling is completed, the temporary supporting device is extended upward at this time, and the temporary supporting effect is achieved; specifically, the telescopic inner cylinder 2 is pushed upward by the lifting driving part 4, so that the telescopic inner cylinder 2 and the supporting cross beam 1 are moved upward; after the supporting cross beam 1 contacts the tunnel roof, the supporting cross beam 1 can be self-adaptively deflected and the angle is automatically adjusted to increase the contact area of the supporting cross beam 1 and the tunnel roof, because the supporting cross beam 1 is hinged to the telescopic inner cylinder 2; the deflection angle of the supporting cross beam 1 is limited within a preset range by the deflection angle limiting structure 5 between the supporting cross beam 1 and the telescopic inner cylinder 2, so that the situation that the supporting effect is reduced due to the too large deflection angle of the supporting cross beam 1 is reduced.

[0035] As shown in Figures 1 to 8 The lifting driving part 4 includes a telescopic oil cylinder, the cylinder end of the telescopic oil cylinder is hinged to the fixed outer cylinder 3, and the piston rod end of the telescopic oil cylinder is hinged to the telescopic inner cylinder 2; the cylinder end of the telescopic oil cylinder has a first connecting part 41, and the first connecting part 41 has a pin hole; the side wall of the fixed outer cylinder 3 has a through hole aligned with the pin hole, and the fixed outer cylinder 3 is connected to the first connecting part 41 through a pin shaft 42; the piston rod end of the telescopic oil cylinder has a second connecting part 43, and the second connecting part 43 also has a pin hole; the telescopic inner cylinder 2 has a through hole aligned with the pin hole of the second connecting part 43, and the telescopic inner cylinder 2 is connected to the second connecting part 43 through the pin shaft 42.

[0036] Through the above setting, the piston rod end of the telescopic oil cylinder is relatively fixed to the telescopic inner cylinder 2, and the cylinder of the telescopic oil cylinder is relatively fixed to the fixed outer cylinder 3; when the telescopic oil cylinder pushes the telescopic inner cylinder 2 upward, the supporting cross beam 1 can be driven to move upward, and then the supporting cross beam 1 can conveniently temporarily support the tunnel roof.

[0037] As an example, the bottom end of the telescopic inner cylinder 2 has an avoiding groove 21 for avoiding the hinged position of the cylinder end of the telescopic oil cylinder; through the above setting, when the telescopic oil cylinder is retracted, the telescopic inner cylinder 2 slides into the fixed outer cylinder 3, and finally the bottom end of the telescopic inner cylinder 2 contacts the bottom end inside the fixed outer cylinder 3, and the avoiding groove 21 at the bottom end of the telescopic inner cylinder 2 can avoid the pin shaft 42.

[0038] It should be noted that the telescopic inner cylinder 2, the fixed outer cylinder 3 and the telescopic oil cylinder together constitute a lifting mechanism, and the above structure of the present application is small in size, simple in structure and convenient to operate; the inner and outer cylinders are rectangular steel pipe structures, and the fixed outer cylinder 3 can guide the telescopic inner cylinder 2 during lifting.

[0039] In some embodiments, as Figures 1 to 8As shown, the top of the telescopic inner cylinder 2 is connected with a hinged seat 22, the hinged seat 22 is provided with a ball head 23, the bottom of the support beam 1 is provided with a ball socket 13 connected with the ball head 23; the ball socket 13 is a groove capable of inserting the ball head 23 into the ball socket 13; the hinged seat 22 is fixed on the top of the telescopic inner cylinder 2 by bolts.

[0040] It should be noted that the telescopic inner cylinder 2 drives the hinged seat 22 and the support beam 1 fixed thereon to rise and fall under the pushing of the telescopic oil cylinder, thereby realizing the supporting effect; when the support beam 1 deflects, the support beam 1 can swing around the ball head 23 to adapt to the change of the angle of the roadway roof.

[0041] In some embodiments, as shown in Figures 1 to 8 As shown, the top of the support beam 1 is provided with a first adjusting through hole 14, the first adjusting through hole 14 is a stepped hole; the top of the telescopic inner cylinder 2 is provided with a second adjusting through hole 24 aligned with the first adjusting through hole 14; the deflection angle limiting structure 5 includes a bolt 51, a spring 52 and a nut 53; the threaded end of the bolt 51 can pass through the first adjusting through hole 14 and the second adjusting through hole 24; the nut of the bolt 51 is located in the stepped hole and abuts against the stepped surface; the spring 52 is sleeved on the outgoing end of the bolt 51; the nut 53 is threadedly connected with the bolt 51; the top end of the spring 52 abuts against the hinged seat 22, and the bottom end of the spring 52 abuts against the nut 53; wherein the diameters of the first adjusting through hole 14 and the second adjusting through hole 24 are both greater than the diameter of the bolt 51; the deflection angle limiting structure 5 further includes a spring seat 54, the spring seat 54 is insertedly connected with the spring 52, and the spring seat 54 is provided with a through hole for the bolt 51 to pass through; the nut 53 abuts against the bottom of the spring seat 54.

[0042] It should be noted that the hinged seat 22 and the support beam 1 are connected together by the spring 52, and the initial pre-tightening force of the spring 52 can keep the support beam 1 horizontal during the lifting process; the structure of the ball head 23 matched with the ball socket 13 between the support beam 1 and the hinged seat 22, during the process of contacting the roof, the roof applies an additional mechanical force to the support beam 1, the support beam 1 is adapted to deflect through the ball head 23 hinged structure, and can be self-adjusted according to the angle of the roof; during the process, the spring force of the spring 52 applied to the support beam 1 can ensure the reliable connection of the support beam 1 and the hinged seat 22.

[0043] Based on the same inventive concept, as shown in Figures 1 to 8 The application also provides a combined drilling and anchoring machine, which comprises a machine body 6 and two sets of temporary support devices, the front end of the machine body 6 is provided with a shovel plate component 61, the two sets of temporary support devices are located on the inner side of the shovel plate component 61, and the two sets of temporary support devices are respectively located at the positions on both sides of the shovel plate component 61; wherein the fixed outer cylinder 3 of the temporary support device is connected to the shovel plate component 61.
