Description

Technical Field

[0001] The utility model relates to the technical field of highway bridge construction, and particularly relates to a precast T-beam concrete pouring operation platform. Background Art

[0002] During the process of precast T-beam concrete pouring for highway bridges, the concrete is transported by a concrete mixer truck to the pedestal to be poured. After being tested and qualified by testers, the concrete is poured into the pouring hopper. Usually, a gantry crane is used to lift the hopper into the bin for pouring. The operator directly steps on the top plate steel bars of the T-beam to discharge, vibrate, and finish the surface. In this way, it is inconvenient for the construction workers to operate, which easily causes the deformation of the top plate steel bars. Without an operation platform, it is inconvenient to finish the surface, and there are safety hazards for personnel to go up and down. At the same time, when the operator directly steps on the steel bars and concrete, it will pollute the concrete. In view of this, the present application provides a small movable precast T-beam concrete pouring operation platform. Content of the Utility Model

[0022] The technical solutions in the embodiments of the present invention are described clearly and completely below. Obviously, the described embodiments are only a part of the embodiments of the present invention, not all of them. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0023] like Figures 1 to 3 As shown, a prefabricated T-beam concrete pouring operation platform includes two support frames 1 arranged side by side, a platform 2 is arranged between the tops of the two support frames 1, ladders 3 are arranged on both sides of the platform 2, the bottom ends of the ladders 3 are connected to the support frames 1 on the same side, a pair of walking wheels 4 are installed on the front and rear sides of the bottom of the support frames 1, and a track groove 5 is opened in the middle of the circumferential surface of the walking wheel 4.

[0024] The operating platform is easy to move. The operator can walk up to the platform 2 via the ladder 3, and then perform operations such as pouring concrete, vibrating, finishing, and roughening on the platform 2. The construction is convenient, the operation is simple, and the safety hazard of personnel going up and down is reduced. At the same time, it avoids the operator stepping directly on the top plate steel bars during construction, causing deformation of the top plate steel bars, so that the construction quality of the top plate steel bars is effectively controlled.

[0025] In addition, a track groove 5 is provided on the running wheel 4, so that the running wheel 4 has two functions of running on the ground and running on the tracks on the ground on both sides of the prefabricated T-beam. Therefore, there is no need to separately provide wheels for running on the ground and wheels for running on the tracks.

[0026] Crossbeams 6 are arranged on both sides of the bottom of the support frame 1 , the travel wheels 4 are installed at the ends of the crossbeams 6 , and a wheel positioning structure for fixing the direction of the travel wheels 4 is arranged between the ends of the crossbeams 6 and the travel wheels 4 .

[0027] By setting up the wheel positioning structure, after the traveling wheel 4 moves onto the track, the traveling wheel 4 is fixed to keep the direction of the traveling wheel 4 parallel to the direction of the track, to prevent the traveling wheel 4 from rotating while walking on the track and causing it to leave the track, thereby ensuring the stability of the operating platform during construction operations.

[0028] The walking wheel 4 includes a wheel frame 4.1, a wheel body 4.2 and a mounting shaft 4.3. The wheel body 4.2 is installed at the bottom of the wheel frame 4.1, and the mounting shaft 4.3 is fixedly installed at the top of the wheel frame 4.1. The mounting shaft 4.3 is rotatably installed on the cross beam 6. The wheel positioning structure includes a positioning groove 7 and a positioning rod 8. The positioning rod 8 is arranged on the side of the cross beam 6 in a liftable manner. The positioning rod 8 is installed on the cross beam 6 in a liftable manner, and the walking wheel 4 is positioned in a state where its orientation is parallel to the length direction of the precast T-beam by inserting the positioning rod 8 into the positioning groove 7.

[0029] When the operation platform is walking on the ground, the positioning rod 8 is located above the positioning groove 7 in the height direction. At this time, the positioning rod 8 is in a separated state from the positioning groove 7. In this state, the walking wheel 4 is rotatably installed on the cross beam 6 through the mounting shaft 4.3, thereby facilitating the performance of the operation platform walking on the ground. When the walking wheel 4 moves onto the track, by inserting the positioning rod 8 into the positioning groove 7, the walking wheel 4 located on the track is fixed, improving the stability of the operation platform walking on the track.

[0030] One positioning groove 7 is provided on each side of the top of the wheel frame 4.1, and one positioning rod 8 is provided on each side of the cross beam 6. The two positioning rods 8 are connected by a slide plate 9. The slide plate 9 is in a "C" shape and is sleeved on the end of the cross beam 6. By controlling the up and down displacement of the slide plate 9 at the end of the cross beam 6, the insertion or extraction of the positioning rod 8 into or from the positioning groove 7 can be controlled.

[0031] Chute grooves 10 are provided on both sides of the cross beam 6. Sliding blocks 11 fixedly installed on the inner wall surfaces of both sides of the slide plate 9 are slidably arranged in the chute grooves 10. The cooperation between the sliding blocks 11 and the chute grooves 10 enables the slide plate 9 to slide stably on the cross beam 6, preventing the slide plate 9 from detaching from the cross beam 6. At the same time, the cooperation between the sliding blocks 11 and the chute grooves 10 maintains the stability of the slide plate 9 during the lifting movement of the slide plate 9, preventing the slide plate 9 from shifting.

[0032] An adjusting bolt 12 is threadedly connected to the slide plate 9, and both ends of the adjusting bolt 12 penetrate through the slide plate 9 and are rotatably installed on the cross beam 6. By rotating the adjusting bolt 12, the slide plate 9 makes a lifting movement, achieving the function of inserting or extracting the positioning rod 8 into or from the positioning groove 7.

[0033] A sliding sleeve 13 is fixedly installed on the cross beam 6. The sliding sleeve 13 is slidably sleeved on the bottom of the support frame 1. The top end of the sliding sleeve 13 is threadedly installed with an adjusting screw rod 14, and both ends of the adjusting screw rod 14 penetrate through the sliding sleeve 13 and are rotatably installed on both sides of the support frame 1. By rotating the adjusting screw rod 14, the displacement of the cross beam 6 in the width direction of the operation platform can be controlled, enabling the walking wheel 4 located on the outside to move to the middle position of the support frame 1 and align with the track. In this way, the support balance of the walking wheel 4 on the support frame 1 is improved. At the same time, the adjusting screw rod 14 can fix the position of the walking wheel 4 in real time.

[0034] When one of the running wheels 4 on the crossbeam 6 is located in the middle of the support frame 1 in the width direction, one end of the sliding sleeve 13 contacts the support frame 1. By using the force of the screw rod on the sliding sleeve 13, the sliding sleeve 13 cooperates with the support frame 1 to limit the running wheel 4 on both sides, further improving the stability and positioning effect of the running wheel 4.

[0035] The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. Any modifications, equivalent substitutions, improvements, etc. made within the spirit and principles of the present invention should be included in the protection scope of the present invention.
