Description

Technical Field

[0001] This utility model relates to the technical field of anti-slip devices, specifically an anti-slip device for a movable mold frame. Background Technology

[0002] A mobile formwork bridge-building machine is a construction machine that uses its own formwork and piers or abutments as supports to cast concrete on-site for bridges. Its main features include high-quality construction, simple operation, and low cost. Abroad, it is widely used in the construction of continuous beams for highway and railway bridges, and is considered a relatively advanced construction method. Domestically, it has begun to be used on expressways and dedicated railway passenger lines. The mobile formwork bridge-building machine mainly consists of: a leg mechanism, supporting trusses, inner and outer formwork, and a main beam lifting mechanism. It can complete a series of construction processes from moving the formwork to casting. For some special construction sections, there may be situations where the longitudinal slope is too large. For example, the longitudinal slope of the concrete box girder may change from the usual 2% to 3%. In this case, the horizontal component of the gravity of the moving formwork is large when it passes through the hole. Therefore, the sliding shoe may slide relative to the concrete box girder during the longitudinal movement of the main beam, which poses a safety hazard. According to the search, Chinese Patent No. CN105064220B discloses a moving formwork anti-slip device, which includes a pier, a concrete box girder set on the pier, and a main beam located on the upper end of the concrete box girder through the rear support leg and the auxiliary support leg. It also includes: a displacement detection device, installed on the auxiliary support leg and connected to the controller, used to detect whether the sliding shoe at the lower end of the auxiliary support leg slides relative to the concrete box girder when the moving formwork is in the longitudinal movement state; and a locking device, installed on the rear support leg and connected to the controller. When the moving formwork is in the longitudinal movement state, if the longitudinal slope of the concrete box girder is too large, causing the slipper to slide relative to the concrete box girder during the longitudinal movement of the main beam, the displacement detection device will send a signal, and the controller will control the locking device to act, locking the main beam relative to the concrete box girder. Although it can lock in time, it is not convenient to move along the concrete box girder, nor is it convenient to move the main beam forward, which can easily cause construction problems.

[0021] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0022] Example:

[0023] Please see Figure 1-5An anti-slip device for a movable formwork includes a pier 1, a concrete box girder 2 set on the pier 1, and a main beam 3 installed on the pier 1 via multiple support slides. It also includes at least four sets of moving mechanisms and at least four sets of locking mechanisms set on the support slides. At least two sets of moving mechanisms are used to drive the support slides to move on the concrete box girder 2, at least two other sets of moving mechanisms are used to drive the main beam 3 to move on the support slides, at least two sets of locking mechanisms are used to lock the support slides to the concrete box girder 2, and at least two other sets of locking mechanisms are used to lock the main beam 3 to the support slides.

[0024] Specifically, the moving mechanism includes a moving frame 5, on which multiple horizontally spaced moving rollers 8 are rotatably connected. The moving frame 5 is also equipped with a driving component to drive the moving rollers 8 to rotate. Grooves are provided on both sides of the concrete box girder 2 and the main beam 3. The multiple moving rollers 8 are all set in the grooves and in contact with the grooves. The driving component facilitates the rotation of the moving rollers 8, thereby enabling relative movement. If the lower moving mechanism is activated, the multiple moving rollers 8 on the lower side rotate in the grooves of the concrete box girder 2, thereby moving the support slide. If the upper moving mechanism is activated, the multiple moving rollers 8 on the upper side rotate in the grooves of the main beam 3, thereby enabling the main beam 3 to move relative to the support slide.

[0025] Specifically, the locking mechanism includes an anti-slip frame 6, on which multiple slide rods 10 are slidably fitted. Anti-slip racks 11 and fixed magnetic strips 12 are fixedly connected to both ends of the slide rods 10, respectively. A fixed rack 15 is provided in the groove, and the anti-slip rack 11 can mesh with the fixed rack 15. A spring 13 is sleeved on the slide rods 10, and both ends of the spring 13 are fixedly connected to the anti-slip rack 11 and the anti-slip frame 6, respectively. A locking device is embedded in the side of the anti-slip frame 6 near the fixed magnetic strip 12. An electromagnetic block 14, which is magnetically repelled by the fixed magnetic strip 12, is provided with power when there is relative movement. The electromagnetic block 14 pushes the fixed magnetic strip 12 outward, and the spring 13 is stretched, thereby disengaging the anti-slip rack 11 from the fixed rack 15. When locking is required, the electromagnetic block 14 is de-energized. Under the action of the spring 13's rebound force, the anti-slip rack 11 is pushed back to engage with the fixed rack 15, thereby preventing relative movement and locking.

[0026] Specifically, the supporting slide includes U-shaped slides 4 located on the left and right sides of the concrete box girder 2 and the main beam 3. The U-shaped slides 4 on both sides are fixedly connected by connecting frames 7. The moving frame 5 and the anti-slip frame 6 are both fixedly connected to the U-shaped slides 4 on the same side. The U-shaped slides 4 facilitate the limitation of the two sides of the concrete box girder 2 or the main beam 3 and facilitate relative movement. The moving frame 5 and the anti-slip frame 6 on the same side are both fixedly connected to the U-shaped slides 4. The connecting frame 7 facilitates the integral fixed connection of the moving mechanism and the locking mechanism on both sides.

[0027] Specifically, the driving component includes a mobile motor 9 fixedly mounted on the mobile frame 5. The mobile motor 9 is used to drive one of the mobile rollers 8 to rotate. Starting the mobile motor 9 facilitates the rotation of one of the mobile rollers 8. With the cooperation of the other multiple mobile rollers 8, relative movement can be started.

[0028] In use, the lower moving mechanism can drive the support slide and the main beam 3 to move forward on the concrete box girder 2. When it reaches the designated position, the support slide can be locked on the concrete box girder 2 by the locking mechanism at the bottom. Then the upper locking mechanism can be released, and the upper moving mechanism can be used to drive the movement. When it moves to a certain position, the main beam 3 can be locked on the support slide by the upper locking mechanism.
