Abstract
Description
Technical Field
[0001] This utility model relates to the technical field of bridge building machine equipment, and more specifically, to an automatic locking device for the movement of a bridge building machine. Background Technology
[0002] In existing technologies, bridge-building machines need to anchor the traveling beam to the existing bridge deck. The traveling beam is connected to the main beam of the hanging basket by a reverse roller to prevent the hanging basket from overturning during travel. During the travel of the hanging basket of the bridge-building machine, the traveling beam needs to be re-laid and anchored on the top surface of the already poured bridge, and then the old traveling beam is removed, so as to realize the relative movement between the main beam of the hanging basket and the traveling beam, and finally complete the travel process.
[0003] During the travel process, the rails and anchor bars of the traveling beam need to be repeatedly removed and installed manually. The construction process is primitive and cumbersome, which is not only time-consuming and labor-intensive, but also inefficient. In addition, the traveling wheels of the bridge-building machine cannot be braked and locked stably, which makes the bridge-building machine prone to slippage, affecting the stability and safety of the construction. Utility Model Content
[0004] The purpose of this invention is to provide an automatic locking device for the movement of a bridge-building machine that can automatically lock and has high stability.
[0005] To achieve the above objectives, the technical solution adopted by this utility model is as follows: An automatic locking device for the movement of a bridge-building machine includes a traveling mounting frame. Two integrally structured axles are fixedly mounted on the lower sides of the traveling mounting frame. Wheels are rotatably mounted on the axles via bearings. An accommodating opening is provided at the upper end of the traveling mounting frame, and a pushing cylinder is fixedly mounted at the bottom of the accommodating opening. A ring plate is fixedly mounted on the inner side wall of the bearing. A sliding cavity penetrating the two axles is opened at the lower end of the traveling mounting frame. A slide rail is fixedly mounted at the bottom of the slide cavity, and two sliders slide on the slide rail. The piston shaft of the pushing cylinder is movably inserted into the slide cavity. A locking element is slidably mounted on the upper part of the axle, and the lower end of the locking element is fixedly connected to the corresponding slider. The lower end of the piston shaft of the pushing cylinder is connected to the two sliders via a lifting pushing mechanism. The piston shaft of the pushing cylinder controls the movement of the two sliders on the slide rail via the lifting pushing mechanism.
[0006] Preferably, the locking component includes an arc-shaped brake plate, with a pull rod fixedly installed at the bottom of the arc-shaped brake plate, and the pull rod passes through the slide groove and is fixedly connected to the corresponding slider.
[0007] Preferably, the outer surface of the ring plate has multiple positioning grooves arranged in a axial annular array, and the arc-shaped brake plate has multiple protruding ribs fixedly installed on one side of the ring plate relative to its position. The protruding ribs are used to engage with the positioning grooves to fix the ring plate.
[0008] Preferably, the lifting side-push mechanism includes a U-shaped seat and two push rods. The two push rods are respectively hinged to both sides of the opening of the U-shaped seat, and the other push rod is hinged to the corresponding position slider. The upper end of the U-shaped seat is fixedly connected to the lower end of the piston shaft of the push cylinder.
[0009] Preferably, a sliding sleeve is fixedly installed at the lower end of the U-shaped seat, and a plug rod inserted into the sliding sleeve is fixedly installed on the slide rail.
[0010] Preferably, the cross-sections of the protruding ribs and the positioning grooves are both corresponding cone shapes.

[0022] See Figures 1-4 As shown, this utility model provides an automatic locking device for the movement of a bridge-building machine, including a traveling mounting frame 1. Two integrally structured wheel axles 3 are fixedly mounted on the lower sides of the traveling mounting frame 1. Wheels 2 are rotatably mounted on the wheel axles 3 via bearings. An accommodating opening 11 is provided at the upper end of the traveling mounting frame 1. A push-type hydraulic cylinder 6 is fixedly mounted at the bottom of the accommodating opening 11. A ring plate 21 is fixedly mounted on the inner side wall of the bearing. A sliding cavity 12 penetrating the two wheel axles 3 is provided at the lower end of the traveling mounting frame 1. A slide rail 7 is fixedly mounted at the bottom of the slide cavity 12. Two sliders 71 are slidably mounted on the slide rail 7. The piston shaft of the push-type hydraulic cylinder 6 is movably inserted into the slide cavity 12. A locking member 4 is slidably mounted on the upper part of the wheel axles 3. The lower end of the locking member 4 is fixedly connected to the corresponding slider 71. The lower end of the piston shaft of the push-type hydraulic cylinder 6 is connected to the two sliders 71 via a lifting push-type mechanism 5. The piston shaft of the push-type hydraulic cylinder 6 controls the movement of the two sliders 71 on the slide rail 7 via the lifting push-type mechanism 5.
[0023] In this embodiment, the locking member 4 includes an arc-shaped brake plate 41, and a pull rod 43 is fixedly installed at the bottom of the arc-shaped brake plate 41. The pull rod 43 passes through the slide groove 31 and is fixedly connected to the corresponding slider 71.
[0024] In this embodiment, the outer surface of the ring plate 21 is provided with a plurality of positioning grooves 22 in an axial annular array, and the arc-shaped brake plate 31 is fixedly installed with a plurality of protruding ribs 42 on one side of the ring plate 21. The protruding ribs 42 are used to engage with the positioning grooves 22 to fix the ring plate 21.
[0025] In this embodiment, the lifting side push mechanism 5 includes a U-shaped seat 51 and two push rods 52. The two push rods 52 are respectively movably hinged to both sides of the opening of the U-shaped seat 51. The other push rod 52 is movably hinged to the corresponding position slider 71. The upper end of the U-shaped seat 51 is fixedly connected to the lower end of the piston shaft of the push cylinder 6.
[0026] Furthermore, to ensure that the U-shaped seat 51 can move vertically stably, in this embodiment, a sliding sleeve 53 is fixedly installed at the lower end of the U-shaped seat 51, and a rod 54 inserted into the sliding sleeve 53 is fixedly installed on the slide rail 7.
[0027] Furthermore, in this embodiment, the cross-sections of the protruding rib 42 and the positioning groove 22 are both corresponding cones, which can improve the efficiency of the engagement between the protruding rib 42 and the positioning groove 22.
[0028] Furthermore, to facilitate the connection between the traveling mounting frame 1 and the main equipment of the bridge building machine, in this embodiment, bolt holes are provided at the four corners of the top of the traveling mounting frame 1, which can be connected to the main equipment of the bridge building machine through bolts.
[0029] Furthermore, to prevent the slider 71 from detaching from the slide rail 7, in this embodiment, the upper part of the slide rail 7 is provided with a T-shaped groove along the length direction, and the lower end of the slider 71 is provided with an integral T-shaped block, which is slidably disposed in the T-shaped groove.
[0030] The specific operating steps are as follows: When it is necessary to keep wheel 2 stably on the bridge, the push cylinder 6 can be opened. The piston shaft of the push cylinder 6 extends and can drive the push rod 52 to deflect downward through the U-shaped seat 51. The other end of the push rod 52 will push the slider 71 to move, so that the arc brake plate 41 fits against the ring plate 21. At the same time, the protruding rib 42 will be inserted into the positioning groove 22 to fix the ring half 21. At this time, the bearing rotation can be effectively prevented, thereby ensuring the stability of wheel 2.
