Description

Technical Field

[0001] The invention discloses an anti-skid device for a pipe segment production line mold, relates to a mechanical device, in particular to an anti-skid device on an automatic production line for concrete pipe segments, and belongs to the field of mechanical engineering. Background Art

[0002] With the rapid development of urban subway transportation, the shield method is becoming increasingly popular in subway tunnel construction. Shield construction ultimately requires the assembly of segments to form a tunnel. The segments are responsible for resisting earth and water pressure, ensuring the tunnel remains open to traffic. Therefore, the quality of the shield segments directly determines the quality of tunnel construction and operational safety. Currently, many segment manufacturers utilize automated production lines, which offer high efficiency, guaranteed segment quality, and reduced labor intensity.

[0003] Automated production lines place segment molds on tracks, which are pushed and slid by hydraulic cylinders. Due to process requirements, the molds sometimes need to be fixed in a station. Due to the enormous thrust of the hydraulic cylinders and the large mass of the molds themselves, inertia often makes it difficult for the molds to stop in time. Furthermore, when the molds are stationary, wear and tear on the tracks and subsidence of the track foundation can cause the tracks to tilt, leading to secondary mold slippage. This poses a safety hazard and disrupts the normal operation of the production line. Summary of the Invention

[0004] The technical problem to be solved by the present invention is to provide an anti-slip device for the mold of an automatic concrete segment production line to address the mold slip problem caused by inertia and track sinking. The technical solution is as follows:

[0005] A slip-prevention device for a pipe segment production line mold includes a braking device and a power device. The key technology is that the braking device includes an outer shell, a connecting splint and a braking support block. The connecting splint is located inside the outer shell. The braking support block is installed on the connecting splint. The retaining shaft is installed on the outer shell. The power device includes an oil cylinder and a damping spring shock absorber connected to the oil cylinder. The damping spring shock absorber and the connecting splint are connected through a main rod.

[0006] A first travel switch and a second travel switch are installed on the main body rod, and a paddle is installed between the first travel switch and the second travel switch.

[0007] A touch hook and a third travel switch are installed on the production line guide device.

[0008] The shell is a concave structure with both left and right ends and an upper end being open.

[0009] The shell is installed in the production line groove through a supporting base.

[0010] One end of the brake support block is provided with 1 to 3 weight-reducing holes.

[0011] The brake support block is V-shaped, and a support plate is provided on the bottom surface of the other end of the brake support block relative to the weight-reducing hole.

[0012] The oil cylinder comprises an oil cylinder body and an oil cylinder piston. The oil cylinder body is mounted on an oil cylinder base. One end of the oil cylinder piston is connected to the oil cylinder body, and the other end is connected to a damping spring shock absorber.

[0013] The damping spring shock absorber comprises a damping body, a damping spring and a damping telescopic rod, the damping spring is sleeved on the damping telescopic rod, the damping body is connected to the oil cylinder body, and the damping telescopic rod is connected to the main body rod.

[0014] Compared with the prior art, the present invention has the following beneficial effects:

[0015] 1. This invention uses the production line's original motion to trigger a switch mechanism, causing the oil cylinder to push the main rod, driving the V-shaped brake support block to stop the mold's lower beam, preventing it from sliding. When the switch mechanism is triggered again, the oil cylinder retracts, placing the V-shaped brake support block horizontally, allowing the upper mold to pass smoothly. This completely eliminates the problem of mold slippage caused by inertia and uneven tracks, significantly reducing safety hazards and significantly improving production safety.

[0016] 2. The device has a simple structure, ingenious design, easy installation, can realize automatic control, high operation accuracy, convenient later maintenance, and low production and use costs. BRIEF DESCRIPTION OF THE DRAWINGS

[0020] See also Figures 1 to 3 A skid-proof device for a pipe segment production line mold includes a braking device and a power device. The key technology is that the braking device includes a shell 8, a connecting splint 12 and a braking support block 11.1. The connecting splint 12 is located in the shell 8. The braking support block 11.1 is installed on the connecting splint 12. A stop shaft 10 is installed above the middle part of the braking support block 11.1 on the shell 8. The power device includes an oil cylinder and a damping spring shock absorber connected to the oil cylinder. The damping spring shock absorber and the connecting splint 12 are connected through a main rod 4.

[0021] A first travel switch 5.1 and a second travel switch 5.2 are mounted on the main rod 4, and a paddle 6 is mounted between the first travel switch 5.1 and the second travel switch 5.2. The first travel switch 5.1 and the second travel switch 5.2 control the oil cylinder.

[0022] The touch hook 7 and the third travel switch 5.3 are installed on the original guide device 15 of the production line, and the third travel switch 5.3 controls the oil cylinder.

[0023] The housing 8 is a concave structure with both left and right ends and an upper end being open.

[0024] The housing 8 is installed in the production line groove through a supporting base 9.

[0025] The brake support block 11.1 is provided with a mounting hole at the lower end of the middle portion and is mounted on the connecting clamping plate 12 by means of mounting screws 14. One end of the brake support block 11.1 is provided with 1 to 3 weight-reducing holes 11.2.

[0026] The brake support block 11.1 is V-shaped, and a support plate 13 is provided on the bottom surface of the other end of the brake support block 11.1 opposite to the weight-reducing hole 11.2.

[0027] The oil cylinder comprises an oil cylinder body 2.1 and an oil cylinder piston 2.2. The oil cylinder body 2.1 is mounted on the oil cylinder base 1. One end of the oil cylinder piston 2.2 is connected to the oil cylinder body 2.1, and the other end is connected to the damping spring shock absorber.

[0028] The damping spring shock absorber comprises a damping body 3.1, a damping spring 3.2 and a damping telescopic rod 3.3. The damping spring 3.2 is sleeved on the damping telescopic rod 3.3. The damping body 3.1 is connected to the oil cylinder body 2.1, and the damping telescopic rod 3.3 is connected to the main rod 4.

[0029] The present invention works as follows:

[0030] 1. When in use, the device is installed in the groove of the production line, directly below the mold. When the movement of the automatic production line itself drives the touch hook 7 to trigger the third travel switch 5.3, the oil cylinder extends the cylinder piston 2.2, pushing the damping spring shock absorber forward, and the damping spring shock absorber drives the main rod 4. The main rod 4 drives the brake support block 11.1 forward through the connecting clamp 12. Since the right half of the brake support block 11.1 has two weight-reducing holes 11.2 and the left half has no holes, the mass of the left half is greater than the mass of the right half, causing it to automatically rotate counterclockwise around the screw 14 under the action of gravity. Therefore, after the brake support block 11.1 is pushed out, the left half will rotate downward to be fixed on the support plate 13, and the right half will tilt up and press against the crossbeam at the bottom of the mold to brake; when the paddle 6 triggers the second travel switch 5.2, the oil cylinder stops pushing;

[0031] 2. When the automatic production line makes a return motion and drives the touch hook 7 to trigger the third travel switch 5.3 again, the cylinder begins to retract the cylinder piston 2.2, and the cylinder piston 2.2 drives the main rod 4 to retract through the damping spring shock absorber. The main rod 4 drives the brake support block 11.1 to move backward through the connecting splint 12. When the paddle 6 triggers the first travel switch 5.1, the cylinder stops retracting; at this time, the brake support block 11.1 just moves to the position of the stop shaft 10, and the stop shaft 10 constrains it horizontally so that the upper mold can pass smoothly.

[0032] The damping spring shock absorber is fixed between the oil cylinder and the main rod. When the oil cylinder is pushed out, the force that can move the main rod is less than the minimum absorption value of the damping spring shock absorber, so the damping spring shock absorber will not expand or contract, so that the oil cylinder pushes the main rod to move through the damping spring shock absorber; when the oil cylinder stops pushing, the mold hits the V-shaped brake support block due to inertia or uneven track, the impact force is within the absorption range of the damping spring shock absorber, and the impact force will be completely absorbed by the damping spring shock absorber; when the oil cylinder is retracted, the damping spring shock absorber drives the main rod to retract.
