[0002] Steel arch is a support measure for underground engineering reinforcement using bent I-beams. It can be combined with anchor rods, shotcrete and steel mesh to form a composite support arch, which is widely used in tunnels, subways, hydropower stations, underground caverns and other projects. During the production process of steel arch, the I-beam needs to be clamped. For example, a Chinese patent document with publication number CN216802309U discloses a steel arch I-beam and connecting plate welding positioner clamping device. The positioner clamping device can stably clamp the I-beam so that the I-beam will not be displaced when the positioner is rotated and displaced.

[0003] During the production of steel arch frames, the positioner needs to rotate and move back and forth to realize the loading and unloading of I-beams; and the distance between the two positioners clamping the I-beams needs to be adjustable to accommodate the clamping of I-beams of different sizes. At the same time, the adjustable spacing between the positioners can avoid the weld position of the I-beam, thereby preventing the welding operation of the I-beam from being affected by the positioner blocking the weld position of the I-beam.

[0004] However, there is no tooling in the prior art that can simultaneously satisfy the requirements of the positioner for rotational motion, forward and backward movement, and adjustable spacing. Utility Model Content

[0026] like Figure 1-4 As shown, this embodiment provides a positioner displacement tooling for tunnel steel arch production, including a base frame 1, the base frame 1 is slidably connected to two mobile platforms 2, the mobile platform 2 is slidably connected to a base 33, and the base 33 is rotatably connected to a positioner 3; the base 1 is provided with a first driving mechanism 14 and a movable first rack 12 and a second rack 13, the first driving mechanism 14 is drivingly connected to a gear meshing with both the first rack 12 and the second rack 13, the first rack 12 is fixedly connected to one of the mobile platforms 2, and the second rack 13 is fixedly connected to the other mobile platform 2.

[0027] Furthermore, the first rack 12 and the second rack 13 are arranged opposite to each other and parallel to each other, and the gear driven and connected by the first driving mechanism 14 is located between the first rack 12 and the second rack 13 .

[0028] The positioner displacement tooling provided in this embodiment of the present application drives the gear to rotate through the first driving mechanism 14. The gear rotation drives the first rack 12 and the second rack 13 to move closer to or away from each other, thereby making the two positioners 3 closer to or away from each other, thereby achieving the distance adjustment between the two positioners 3.

[0029] Specifically, Figure 1The side of the middle I-beam 4 facing the base frame 1 is a front view. When the first driving mechanism 14 rotates clockwise, the first rack 12 and the second rack 13 move toward the outside of the base frame 1. At this time, the two positioners 3 move away from each other and the distance between them becomes larger; when the first driving mechanism 14 rotates counterclockwise, the first rack 12 and the second rack 13 move toward the center of the base frame 1. At this time, the two positioners 3 move close to each other and the distance between them becomes smaller.

[0030] Exemplarily, the first driving mechanism 14 may be a motor and a reducer meshed with the motor, the motor drives the reducer to rotate, the reducer drives the gear to rotate, thereby driving the first rack 12 and the second rack 13 to move.

[0031] Furthermore, the first rack 12 and the second rack 13 are both fixedly connected to the mobile platform 2 via a connecting frame 15 .

[0032] Furthermore, a first guide rail 11 is provided on the base frame 1 , and the mobile platform 2 is slidably connected to the first guide rail 11 .

[0033] In this embodiment, when the first driving mechanism 14 drives the first rack 12 and the second rack 13 to move closer to or away from each other, the first rack 12 and the second rack 13 respectively drive the two mobile platforms 2 and the base 33 and the positioner 3 thereon to move closer to or away from each other through the connecting frame 15.

[0034] It should be noted that the internal structure of the positioner 3 provided in the present application is the same as the internal structure of a steel arch frame I-beam and connecting plate welding positioner clamping device disclosed in the Chinese patent document with publication number CN216802309U in the prior art, and the internal structure of the positioner 3 is not repeated here.

[0035] In some embodiments, the mobile platform 2 is provided with a second guide rail 21 , and the base 33 is slidably connected to the second guide rail 21 .

[0036] Furthermore, the base 33 is fixedly connected to a second driving mechanism 23, the second driving mechanism 23 is drivingly connected to a first gear 24, and the second driving mechanism 23 is used to drive the first gear 24 to rotate; the mobile platform 2 is provided with a third rack 22 parallel to the second guide rail 21, and the third rack 22 is meshed with the first gear 24.

[0037] In this embodiment, since the third rack 22 is meshed with the first gear 24, the second drive mechanism 23 drives the first gear 24 to rotate, so that the second drive mechanism 23, the base 33, and the positioner 3 can move along the second guide rail 21, and then the positioner 3 can move forward and backward, thereby realizing the loading and unloading of the I-beam 4. Exemplarily, the second drive mechanism 23 can be a motor.

[0038] In some embodiments, a rack portion 31 is provided on the periphery of the positioner 3, and the rack portion 31 has a plurality of teeth. The base 33 is fixedly connected to a third driving mechanism 34, and the third driving mechanism 34 is drivingly connected to a second gear 35. The third driving mechanism 34 is used to drive the second gear 35 to rotate, and the second gear 35 is meshed with the rack portion 31.

[0039] In this embodiment, since the second gear 35 is meshed with the rack portion 31 , the third driving mechanism 34 drives the second gear 35 to rotate, so that the rack portion 31 meshed with the second gear 35 rotates, thereby realizing the rotational movement of the positioner 3 .

[0040] Furthermore, the positioner 3 has a clamping portion 32 for clamping the I-beam 4. The I-beam 4 is clamped by the clamping portion 32 having an opening.

[0041] Furthermore, a plurality of rotatable roller shafts 36 are disposed in the base 33 , and the roller shafts 36 abut against an outer peripheral surface 39 of the positioner 3 .

[0042] In this embodiment, when the positioner 3 rotates, a plurality of supporting wheel shafts 36 abut against the outer peripheral surface 39 of the positioner 3, and can support the positioner 3, so that the positioner 3 can rotate more smoothly.

[0043] Furthermore, the base 33 is fixedly connected to a plurality of rotatable pressing wheels 37 via a connecting rod 38 , and the pressing wheels 37 abut against an inner circumferential surface 311 of the rack portion 31 .

[0044] In this embodiment, when the positioner 3 rotates, the plurality of pressure wheels 37 abut against the inner circumferential surface 311 of the rack portion 31 , and can press the positioner 3 , so that the positioner 3 rotates more smoothly.

[0045] Therefore, the present application fixes the positioner 3 by setting the pressure wheel 37 and the supporting wheel shaft 36 to prevent displacement of the positioner 3 when it rotates. The pressure wheel 37 and the supporting wheel shaft 36 press the positioner 3 together, so that the rack part 31 of the positioner 3 and the second gear 35 are tightly meshed together, while ensuring that the positioner 3 can rotate smoothly, the rack part 31 and the second gear 35 are prevented from being separated, so that the positioner 3 can rotate normally, ensuring the normal operation of the equipment.

[0046] When in use, the positioner displacement fixture is installed between the loading conveyor line and the unloading conveyor line of the I-beam 4. When the loading conveyor line receives materials, the second drive mechanism 23 drives the first gear 24 to rotate, so that the base 33 and the positioner 3 move along the second guide rail 21 to the loading conveyor line, and the clamping part 32 of the positioner 3 clamps the I-beam 4 on the loading conveyor line. The third drive mechanism 34 drives the positioner 3 to rotate, so that the positioner 3 rotates 90°, so that the opening of the clamping part 32 lifts the I-beam 4 upward. The second drive mechanism 23 drives the positioner 3 to move to the unloading conveyor line, and the third drive mechanism 34 drives the positioner 3 to rotate, so that the opening of the clamping part 32 faces the unloading conveyor line, opens the clamping part 32, and drops the I-beam 4 onto the unloading conveyor line to realize the unloading work.

[0047] The spacing between the two positioners 3 is adjustable, and the first drive mechanism 14 drives the first rack 12 and the second rack 13 to move closer to or farther from each other, thereby making the two positioners 3 move closer to or farther from each other, thereby achieving the spacing adjustment between the two positioners 3 to adapt to the clamping of I-beams of different sizes. At the same time, if there is a weld in the middle of the I-beam 4 and plate welding is required, the spacing between the two positioners 3 is adjusted by the first drive mechanism 14 to avoid the weld position of the I-beam 4, so as to avoid affecting the welding operation of the I-beam 4 due to the positioner 3 blocking the weld position of the I-beam 4.

[0048] The positioner displacement tooling provided in the present application can simultaneously satisfy the requirements of the positioner for rotational motion and forward and backward movement, and has adjustable spacing. It is stable in operation, safe and reliable, and has firm clamping, and can simultaneously satisfy the requirements of clamping, transportation and welding of I-beams.

To make the description concise, not all possible combinations of the technical features in the above embodiments are described. However, as long as there is no contradiction in the combination of these technical features, they should be considered to be within the scope of this specification.

It should be pointed out that for ordinary technicians in this field, several modifications and improvements can be made without departing from the concept of the utility model, which all belong to the protection scope of the utility model.
