Description

Technical Field

[0001] The utility model belongs to the technical field of bridge construction, and in particular relates to a movable telescopic chute for a bridge deck system. Background Art

[0002] During the construction of retaining walls on bridge deck systems, chutes are used to pour concrete for the retaining walls. However, during the actual pouring process, the height of retaining walls on different bridge decks varies, requiring the height of the chute to be adjusted according to the actual construction conditions.

[0003] Chutes are disclosed in the prior art. For example, patent CN216305403U discloses a chute device for material pouring, which includes a chute body and a lifting mechanism. The chute body is tilted relative to the top of the ground and is used to convey materials. One end of the lifting mechanism is connected to the bottom side of the chute body, and the other end is used to contact the ground. The lifting mechanism is used to adjust the inclination angle between the chute body and the ground and / or adjust the height of the chute body from the ground. The chute device for material pouring disclosed in this patent uses a lifting mechanism connected to the chute body. During use, the lifting mechanism can be operated to adjust the inclination direction of the chute body or the height of the chute body from the ground.

[0004] It is undeniable that the chute device for material pouring disclosed in this patent can indeed achieve the above-mentioned effects, but it still has certain shortcomings: when adjusting with the help of the lifting assembly, it is necessary to adjust the adjustment assembly at multiple positions, and it is necessary to ensure that after the adjustment is completed, the universal wheels in the adjustment assembly are all in contact with the ground to avoid the chute body at the top from tilting. The entire adjustment process takes a long time. In addition, the lifting assembly mainly relies on a threaded shaft and an adjustment member to adjust the height or angle of the chute body, but its threaded shaft is exposed to the external environment. Especially when pouring concrete, the threaded shaft may adhere to concrete or other materials in the construction environment, causing the threaded shaft and the adjustment member to become stuck, and thus the function of the adjustment assembly cannot be realized.

[0005] The information disclosed in this background technology section is only intended to increase the understanding of the overall background of the present invention, and should not be regarded as an admission or any form of suggestion that the information constitutes the prior art already known to those skilled in the art.

Based on the embodiments of this utility model, all other embodiments obtained by those skilled in the art without making any creative efforts are within the scope of protection of this utility model.

[0034] Example

[0035] See attached Figure 1-4 , a movable telescopic chute for a bridge deck system, comprising:

[0036] The base frame 10 is rectangular and has self-locking universal wheels 11 installed at the bottom of the base frame 10. The self-locking universal wheels 11 can be used to easily move the entire device;

[0037] The telescopic member 20 is arranged on one side of the base frame 10, and the telescopic member 20 includes two first guide posts 21 symmetrically fixed to one end of the base frame 10, a first support frame 22 that slides and guides with the first guide posts 21, two second guide posts 23 symmetrically fixed to the other end of the base frame 10, a second support frame 24 that slides and guides with the second guide posts 23, and a limiting pin 25 for fixing the relative position between the first guide post 21 and the first support frame 22 and for fixing the relative position between the second guide post 23 and the second support frame 24; wherein, the second guide post 23 and the second support frame 24 are respectively provided with a plurality of first guide posts 21 and 22, and a plurality of second guide posts 23 and a plurality of second support frames 24. The height of the guide column 23 is higher than that of the first guide column 21; the first support frame 22 and the second support frame 24 have the same structure. The first support frame 22 includes two guide cylinders 221 symmetrically arranged and sleeved on the first guide column 21 at corresponding positions, a connecting rod 222 fixedly connecting the guide cylinders 221 at both ends, and two fixing plates 223 fixedly connecting the guide cylinders 221 at both ends and located above the connecting rod 222 and distributed in parallel with each other. It can be clearly seen from the accompanying drawings that the connecting rod 222 and the fixing plate 223 are located between the two guide cylinders 221;

[0038] A chute body 30 is fixedly connected at one end to the top of the first support frame 22 and at the other end to the top of the second support frame 24 in an inclined state. A plurality of reinforcing rods 31 are evenly arranged and fixed on the top of the chute body 30. The chute body 30 is located at one end of the first support frame 22 and is lower than the end of the second support frame 24.

[0039] An operating platform 40 is arranged on the other side of the basic frame 10, and the operating platform 40 includes four support columns 41 distributed in a rectangular shape and a support plate 42 fixed to the top of the four support columns 41; the bottom of the support column 41 is fixedly connected to the basic frame 10, and guardrails 43 are fixed on the outside and both ends of the support plate 42; a plurality of ladder rods 44 are welded between the two support columns 41 at one end of the operating platform 40 at intervals above and below; an entrance and exit 431 is left on the guardrail 43 located at one end of the ladder rod 44.

[0040] In this embodiment, the first guide column 21 and the second guide column 23 are provided with a plurality of clearance holes 211 that penetrate the column body along their radial direction, and the plurality of clearance holes 211 are distributed along the axial direction of the first guide column 21 and the second guide column 23; the guide cylinder 221 is provided with a limiting hole 2211 corresponding to the clearance hole 211, and the limiting pin 25 passes through the limiting hole 2211 and the clearance hole 211 at the corresponding position, so that the guide cylinder 221 can be limited to the first guide column 21 and the second guide column 23 respectively with the help of the limiting pin 25, thereby fixing the relative position between the first guide column 21 and the first support frame 22, and the relative position between the second guide column 23 and the second support frame 24. It should be supplemented here that in the actual construction process, a cotter pin is inserted at the end of the limiting pin 25.

[0041] In addition, in this embodiment, a connecting plate 32 is fixed to the bottom of each end of the chute body 30. The connecting plate 32 is inserted into the gap between the two fixing plates 223. Bolts are passed through the fixing plates 223 and the connecting plate 32, and then screwed into nuts to secure the connecting plate 32 and the fixing plates 223. This arrangement facilitates subsequent disassembly of the chute body 30 for cleaning, maintenance, or replacement.

[0042] During use, the worker uses the self-locking universal wheels 11 to move the entire device to the location to be constructed. Then, the height of the chute body 30 is adjusted according to the height of the retaining wall to be cast. Specifically, while maintaining the height of the chute body 30, all the limit pins 25 are removed, and the first support frame 22 and the second support frame 24 are moved up and down. Since the chute body 30 is fixedly connected to both the first support frame 22 and the second support frame 24, the chute body 30 will move up and down synchronously. Moreover, due to the presence of the chute body 30, the first support frame 22 and the second support frame 24 will also move synchronously, achieving synchronous adjustment of the first support frame 22 and the second support frame 24, which can not only improve adjustment efficiency but also ensure uniformity in height adjustment. After the chute body 30 reaches the appropriate height, the limit pin 25 is inserted through the limit hole 2211 and the corresponding clearance hole 211, thereby fixing the relative position between the first guide column 21 and the first support frame 22, and the relative position between the second guide column 23 and the second support frame 24, thereby achieving the height adjustment of the chute body 30. After the height of the chute body 30 is adjusted, the retaining wall can be cast.

[0043] During this adjustment process, the staff can use the ladder rod 44 to pass through the entrance and exit 431 to enter the support plate 42 of the operating platform 40, so as to clearly observe the relative position relationship between the retaining wall and the discharge port of the chute body 30, and facilitate the adjustment of the chute body 30 to the appropriate height and position. The safety of the staff at the top of the operating platform 40 can be ensured by the provided guardrail 43.
