Description

Technical Field

[0001] The utility model relates to the technical field of bridge hanging basket construction, in particular to an improved bridge construction hanging basket. Background Art

[0002] The bridge basket is the main equipment in cantilever construction. It can be divided into four types according to the structural form: truss type, cable-stayed type, steel type and mixed type. No matter which type it is, it will move forward after completing the construction of this section of the bridge deck. Due to the inherent forward-leaning structure of the bridge basket itself, it has a tendency to tilt forward and fall after it is separated from the fixation (it must be separated from the fixation to move). In order to further reduce the probability of this forward tilting and falling during the movement, technical personnel in this field have improved it and proposed an improved bridge construction basket.

DETAILED DESCRIPTION

[0019] In order to make the purpose, technical solution and advantages of the embodiments of the present utility model clearer, the technical solution in the embodiments of the present utility model will be clearly and completely described below in conjunction with the accompanying drawings in the embodiments of the present utility model.

[0020] The present application provides an improved bridge construction hanging basket, which is mainly used to further reduce the probability of the bridge hanging basket tipping forward and falling during movement, and provides the following technical solutions. Figure 1-Figure 4 Make a detailed description:

[0021] An improved bridge construction hanging basket comprises a track 1, a main truss 2, a hanging basket 3, and a traveling wheel 4, wherein the specific connection method of the track 1, the main truss 2, the hanging basket 3, and the traveling wheel 4 belongs to the prior art, and other detailed structures should also be included, which will not be elaborated in detail here. The main improved part is that it also includes a counterweight box 5 fixedly installed at the tail end of the main truss 2, and a telescopic arm 6 is pivotally connected to the top side of the counterweight box 5. The telescopic arm 6 is adjustable in length and is axially connected to a rail car 7 at one end away from the counterweight box 5. The rail car 7 can travel along the track 1 and can be changed from a rotating connection to a fixed connection with the telescopic arm 6. During specific operation: when the bridge hanging basket cancels the fixation between it and the track 1 and moves forward (the track 1 here is fixed on the bridge deck), the overall structure obviously has a tendency for one end of the hanging basket 3 to fall down (please refer to Figure 1 ), the present application can make the main truss 2 longer as a whole by setting the telescopic arm 6 (the telescopic arm 6 is unfolded into Figure 2), which is equivalent to increasing the lever arm (regarding the main truss 2, the basket 3, and the telescopic arm 6 as a lever), which can reduce the probability of the bridge basket tilting forward. At the same time, the rail car 7 is buckled on the track 1, which further strengthens the connection between the bridge basket and the track 1 and reduces the risk of the bridge basket tilting forward (in the prior art, the track 1 is installed on the bridge in sections. Such a design can increase the connection with a longer track 1, thereby reducing the risk of the bridge basket tilting forward).

[0022] like Figure 3 As shown, in order to further optimize the technical solution, the counterweight box 5 includes a metal box 501 which is hollow inside and fixed to the main truss 2, and a pull rod 502 which is fixed to the top of the metal box 501 and one end of which is fixed to the main truss 2. The other end of the pull rod 502 is rotatably connected to the telescopic arm 6. The provision of the pull rod 502 can increase the connection strength between the telescopic arm 6 and the main truss 2, and a water inlet is provided at the top side of the metal box 501 and a water drain port is provided at the bottom side of the metal box 501. Water is added to the metal box 501 through the water inlet to increase its weight, thereby increasing the counterweight and reducing the risk of overall forward tilting. The water drain port can be provided to release water when it is not needed.

[0023] like Figure 3 , Figure 4 As shown, the specific structure of the telescopic arm 6 is: it includes a sleeve rod 601 rotatably connected to the end of the pull rod 502, and an inner rod 602 that cannot be dislodged is slidably arranged in the sleeve rod 601 (a raised hanging platform is arranged at the tail of the inner rod 602, so it cannot be dislodged from the sleeve rod 601, see the attached Figure 4 ), the extended end of the inner rod 602 is rotatably connected to the rail car 7, and also includes a limiting mechanism 603 that limits the relative sliding of the sleeve rod 601 and the inner rod 602, wherein the limiting mechanism 603 includes a first through hole 6031 and a second through hole 6032 constructed on the sleeve rod 601 and a threaded hole constructed on the inner rod 602, and a hand screw 6033 that penetrates the first through hole 6031 or the second through hole 6032 is connected to the threaded hole. When the inner rod 602 and the sleeve rod 601 need to slide relative to each other, the hand screw 6033 is pulled out. The screw rod 6033 is used to release the restriction between the inner rod 602 and the sleeve rod 601. When the position of the first through hole 6031 or the second through hole 6032 is reached (that is, when the threaded hole is aligned with the first through hole 6031 or the second through hole 6032), the hand screw rod is screwed on to complete the relative restriction between the extended or shortened inner rod 602 and the sleeve rod 601, wherein the purpose of the extension is to provide a longer force arm, and the purpose of the shortening is to allow the inner rod 602 to be retracted to avoid affecting the placement of other workpieces during construction.

[0024] like Figure 3As shown, the specific structure of the rail vehicle 7 is as follows: it includes a seat plate 701, a U-shaped rotating portion 702 is constructed on the seat plate 701, the inner rod 602 extends into the U-shaped rotating portion 702 and is rotatably connected to the inner rod 602 through an axle rod, and the two realize a rotatable connection mode. At the same time, in order to realize the two in a fixed mode, a limiting hole 8 is correspondingly constructed on the U-shaped rotating portion 702 and the inner rod 602, and a limiting rod 9 is inserted into the limiting hole 8 to limit the relative rotation of the inner rod 602 and the U-shaped rotating portion 702. By inserting the limiting inner rod 602 into the limiting hole 8, the inner rod 602 and the U-shaped rotating portion 702 can be limited and cannot rotate. In order to enable the rail vehicle 7 to be subsequently installed or removed, four matrix-distributed slide grooves 703 are constructed on the seat plate 701, and a slider 704 is slidably arranged in the slide groove 703. A roller 705 is rotatably installed on the side of the slider 704, and the roller 705 can roll in the track 1. It also includes an adjusting mechanism 706, which is used to control the position of the slider 704 in the length direction of the slide groove 703. The adjusting mechanism 706 makes the slider 704 slide in the slide groove 703 and then drives the roller 705 to be stuck on the side of the track 1 or away from the side of the track 1 to achieve the installation of the roller 705 of the rail car 7. At the same time, the adjusting mechanism 706 specifically includes a plurality of support plates 7061 fixed on the top of the seat plate 701, and a bidirectional screw rod 7062 with a thread passing through the slider 704 is rotatably installed on the support plate 7061. The end of the bidirectional screw rod 7062 is constructed in a hexagonal shape. By rotating the bidirectional screw rod 7062, the two sliders 704 can be moved closer to or away from each other to drive the rolling movement.
