TECHNICAL FIELD
[0001] The utility model relates to a subway cement segment production equipment, especially a subway cement segment troweling structure. BACKGROUND
[0002] The subway cement segment is the concrete material built in the subway tunnel, the subway cement segment is arc-shaped, and one unit of the subway tunnel is generally composed of six subway cement segments. SUMMARY
[0003] The utility model provides a subway cement segment troweling structure that is small in size, good in troweling effect and high in flexibility, solves the technical problems of large size, unsatisfactory troweling effect and insufficient flexibility in the troweling equipment in the prior art.
[0004] The above technical problems of the utility model are solved through the following technical scheme: a subway cement segment troweling structure, which comprises a fixing frame fixed on a truss, a driving structure is installed on the fixing frame, the driving structure is connected with an oscillating structure, the oscillating structure is connected with a floating trowel through a connecting structure, and the floating trowel oscillates under the driving of the oscillating structure.
[0005] Preferably, the driving structure is a speed reducer motor, the oscillating structure is a worm and gear structure, and the output shaft of the speed reducer motor serves as the worm part in the oscillating structure.
[0006] As preferred, the connecting structure comprises two synchronously swinging connecting rods on both sides of the driving structure, and the connecting rods are connected with the floating trowel through connecting seats.
[0007] As preferred, the end of the connecting rod is provided with a supporting seat, and the supporting seat is fixed on the connecting rod fixing frame. The connecting rod is supported through the supporting seat, so as to ensure the stability of the transmission of the connecting rod.
[0008] As preferred, the connecting seat comprises an L-shaped connecting plate, a stand is arranged below the L-shaped connecting plate, and one end of the stand is connected with the floating trowel. The L-shaped connecting plate connects the horizontal connecting rod with the vertical stand, so that the connecting plate and the stand can swing synchronously.
[0009] As preferred, the stand is a telescopic rod structure, a spring is sleeved on the stand, and one end of the spring abuts against the floating trowel. In use, the spring abuts against the subway cement segment, so that the floating trowel is always in contact with the subway cement segment during the troweling process, thereby ensuring the troweling effect.
[0010] As preferred, the floating trowel is a U-shaped section steel. The U-shaped section steel forms two blocking surfaces on the front and back sides, so that the troweled concrete can be blocked from turning upward when the floating trowel trowels from both sides of the subway cement segment, thereby affecting the troweling effect of the floating trowel.
[0011] As preferred, the fixing frame comprises a motor fixing frame and a connecting rod fixing frame, the motor fixing frame is fixed on the truss, and the connecting rod fixing frame is fixed with the motor fixing frame.
[0012] As preferred, the length of the floating trowel is not less than the length of the subway cement segment to be treated, and the width of the floating trowel is 1 / 40-1 / 20 of the arc surface of the subway cement segment to be treated. The floating trowel has small volume and good flexibility, and the troweling uniformity is good.
[0013] Therefore, the troweling structure of the subway cement segment has the following advantages: the floating trowel with small volume is used for troweling operation, and has good flexibility; the floating trowel is driven to swing according to the troweling direction through the swinging structure, so that the floating trowel is suitable for subway cement segments with various radii and sizes, and has wide application range. The floating trowel is pressed on the surface of the subway cement segment through the spring, so that the troweling effect is good, and the quality stability is high. BRIEF DESCRIPTION OF DRAWINGS

[0018] The technical scheme of the utility model will be further specifically explained below by examples in combination with the drawings.
[0019] Embodiment:
[0020] As Figure 1 and 2 and 3, a subway cement segment finishing structure, comprising a fixed frame fixed on a truss 12, the fixed frame comprising a vertical motor fixed frame 1 and a horizontal connecting rod fixed frame 4. The lower part of the motor fixed frame 1 is connected with the connecting rod fixed frame 4 through a door-shaped frame 2 by means of bolts.
[0021] A reduction motor 3 is installed on the motor fixed frame 1, the reduction motor is connected with a worm and gear structure, the output shaft of the reduction motor is used as a worm part in the swing structure, the worm and gear structure is connected with two connecting rods 5, one end of the two connecting rods 5 is connected with the worm and gear structure, the other end of the connecting rod 5 is supported through a support seat 6. The connecting rod 5 extending out of the support seat is connected with an L-shaped connecting plate 7, a stand column 9 is installed below the L-shaped connecting plate 7, the stand column 9 is a telescopic rod structure. The other end of the stand column 9 is fixed with a floating trowel 10, a spring 8 is sleeved on the stand column 9, and the end of the spring 8 abuts against the floating trowel 10. The floating trowel 10 is made of U-shaped section steel.
[0022] As Figure 4 shown, the finishing structure is installed on the truss 12, and a driving structure moving in up-down, left-right, front-back and other directions is installed on the truss 12. The length of the floating trowel 10 is not less than the length of the subway cement segment 11 to be processed, and the width of the floating trowel 10 is 1 / 30 of the arc surface of the subway cement segment 11 to be processed. The driving structure on the truss drives the motor fixed frame to move from the left to the right to finish the subway cement segment, the reduction motor drives the worm and gear to rotate, so that the floating trowel is tilted at an angle and adheres to the surface of the subway cement segment, at the same time, the spring keeps the floating trowel pressed on the surface of the subway cement segment to finish the surface and ensure the finishing effect. After finishing the surface from the left to the vertex of the arc surface of the subway cement segment, the truss driving structure drives the motor fixed frame to move to the right surface of the subway cement segment, so that the floating trowel moves from the right to the left, the reduction motor drives the worm and gear to rotate again, so that the floating trowel rotates again and adheres to the surface of the subway cement segment again, and moves from the right side to the vertex of the arc surface of the subway cement segment to finish the surface on the right side.
