[0002] During the construction of the bridge deck system of the overpass bridge, in order to facilitate on-site construction, bamboo plywood is usually set below the welded wet joint steel bar 9 to catch the slag. When welding 1 to 2 meters, the bamboo plywood is moved to the next area to catch the slag by rope on the bamboo plywood. However, during the movement, because it needs to pass through the welded wet joint steel bar 9, the bamboo plywood often tilts and leaks slag or even falls onto the road below, which is very easy to cause safety accidents. Utility Model Content
[0003] In view of the problems existing in the prior art, the purpose of this utility model is to provide a mobile slag receiving device for wet joint construction.
[0004] To solve the above problems, the present invention adopts the following technical solution:

The track is arranged along the longitudinal direction of the beam, and both ends of the track are fixed to the shear reinforcement on the surface of the beam by the fixing rope, so that the track is suspended below the beam. There is a height difference between the two ends of the track. The slag receiving hopper is slidably connected to the track with its upper end facing upward. The lower pulley is located at the top of the higher end of the track, and the upper pulley is located on the surface of the beam. The traction ring is located on the side of the slag receiving hopper facing the lower pulley.

The two ends of the first U-shaped reinforcing bars are respectively inserted into the steel pipes at one end of the two square steel bars to fix the width between the square steel bars. The two first U-shaped reinforcing bars are respectively connected to the two ends of the two square steel bars. The lower pulley is arranged in the middle of one of the first U-shaped reinforcing bars. The bottom of the slag receiving hopper is slidably connected to the two square steel bars.
[0007] Preferably, the bottom of the slag receiving hopper is connected to a downward-facing U-bolt, the bottom of the square steel is fitted with a steel plate, the U-bolt surrounds the top and both sides of the square steel, and the two ends of the U-bolt pass through the steel plate and are fixed by nuts.

[0012] The beneficial effects of this utility model are:
[0013] Compared with existing technologies, the advantages of this utility model are:
[0014] This invention suspends the track below the beam using a fixed rope. When the slag hopper needs to be moved, the slag hopper can be pulled along the track by pulling the traction rope on the beam surface. Because there is a height difference between the two ends of the track, and the traction ring, upper pulley, lower pulley, and traction rope are all located at the higher end of the track, releasing the traction rope allows the slag hopper to slide down the track, achieving movement in the opposite direction. With the track fixedly suspended below the beam, the track remains stationary while the slag hopper moves, allowing it to slide smoothly back and forth along the track. This solves the problem of slag falling due to shaking or tilting during slag hopper movement. Attached Figure Description

Detailed Implementation
[0019] 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.
[0020] like Figures 1-3 As shown, this utility model provides a technical solution: a mobile slag receiving device for wet joint construction, including a track, a slag receiving hopper 5, a fixing rope 7, an upper pulley 11, a traction rope 12, a lower pulley 16, and a traction ring 18. The track is arranged along the longitudinal direction of the beam 6, and both ends of the track are fixed to the shear reinforcement 8 on the surface of the beam 6 by the fixing rope 7, so that the track is suspended below the beam 6. There is a height difference between the two ends of the track. The slag receiving hopper 5 is slidably connected to the track with its upper end facing upward. The lower pulley 16 is located at the top of the higher end of the track. The upper pulley 11 is located on the surface of the beam 6. The traction ring 18 is located on the side of the slag receiving hopper 5 facing the lower pulley 16. One end of the traction rope 12 is fixed to the traction ring 18, and the other end passes through the lower pulley 16 at the end of the track and the upper pulley 11 on the surface of the beam 6 and is then fixed to the shear reinforcement 8 on the surface of the beam 6.
[0021] This invention suspends the track below the beam 6 using a fixing rope 7. When the slag-receiving hopper 5 needs to be moved, the slag-receiving hopper 5 can be pulled along the track by pulling the traction rope 12 on the surface of the beam 6, moving the slag-receiving hopper 5 below the welding position of the wet joint reinforcement 9. The traction rope 12 can then be fixed to any shear reinforcement 8 on the surface of the beam 6. Due to the height difference between the two ends of the track, the initial position of the slag-receiving hopper 5 is set at the lower end of the track, while the traction ring 18, upper pulley 11, lower pulley 16, and traction rope 12 are all set at the higher end of the track. The traction rope 12 pulls the slag-receiving hopper 5 in an uphill state. Releasing the traction rope 12 allows the slag-receiving hopper 5 to slide down the track, achieving the reverse movement of the slag-receiving hopper 5.
[0022] The track of this utility model is fixedly suspended below the beam 6. When the slag hopper 5 is moved, the track remains stationary and the slag hopper 5 slides smoothly back and forth along the track, which solves the problem of welding slag falling off due to shaking or tilting when the slag hopper 5 is moved.
[0023] Furthermore, the track includes two parallel square steel bars 1 and two first U-shaped reinforcing bars 15. The square steel bars 1 are arranged along the longitudinal direction of the beam 6. The fixing rope 7 is connected to the end of the square steel bars 1. Steel pipes 14 are welded to both ends of the square steel bars 1. The two ends of the first U-shaped reinforcing bars 15 are respectively inserted into the steel pipes 14 at one end of the two square steel bars 1 to fix the width between the square steel bars 1. The two first U-shaped reinforcing bars 15 are respectively connected to the two ends of the two square steel bars 1. The lower pulley 16 is set in the middle of one of the first U-shaped reinforcing bars 15. The bottom of the slag receiving hopper 5 is slidably connected to the two square steel bars 1. This achieves double-track support for the slag receiving hopper 5, further avoiding the risk of the slag receiving hopper 5 tilting.
[0024] Furthermore, the bottom of the slag receiving hopper 5 is connected to a downward-facing U-bolt 4, the bottom of the square steel 1 is fitted with a steel plate 2, the U-bolt 4 surrounds the top and both sides of the square steel 1, and the two ends of the U-bolt 4 pass through the steel plate 2 and are fixed by nuts 3, thereby realizing the slag receiving hopper 5 slidingly connected to the track.
[0025] Furthermore, perforated steel plates 13 are welded to both ends of the square steel 1, and the two ends of the fixing rope 7 are respectively connected to the perforated steel plates 13 and the shear reinforcement 8 on the surface of the beam 6, thereby fixing the square steel 1 with the fixing rope 7.
[0026] Specifically, the height difference between the two ends of the track should ideally be 10cm.
[0027] Furthermore, a horizontally extending fixed steel bar 10 is provided through the center of the upper pulley 11. The fixed steel bar 10 serves as the pivot of the upper pulley 11. Both ends of the fixed steel bar 10 are fixed to the shear bars 8 on the surface of the beam 6, thereby achieving rotational support for the upper pulley 11. Specifically, both ends of the fixed steel bar 10 can be tied or welded to the shear bars 8 on the surface of the beam 6.
[0028] Furthermore, a second U-shaped steel bar 17 is provided at the top of the first U-shaped steel bar 15. The second U-shaped steel bar 17 is arranged downwards, with its two ends connected to the top of the first U-shaped steel bar 15. Its middle horizontal section is connected through the center of the lower pulley 16 as the pivot of the lower pulley 16, thereby realizing the rotational support of the lower pulley 16.
[0029] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
