Description

Technical Field

[0001] The utility model relates to a feeding device, in particular to a feeding device for bridge construction. Background Art

[0002] Bridge construction involves multiple key steps and precautions to ensure the structural safety and service life of the bridge; such as: foundation construction, deck construction, etc. Since the height of the bridge is relatively high, aerial work occupies most of the construction process.

[0003] During aerial work, a construction platform is usually set up in advance or work is carried out on the completed part of the bridge. Due to the limited bearing capacity of the construction platform and the unaccepted bridge, materials are stacked in a stockyard with a relatively low height, and the materials need to be transported to a construction area with a relatively high height when needed. Common feeding methods include crane hoisting and tower crane hoisting.

[0004] Since the length of the bridge is relatively long, when using the tower crane hoisting method for feeding, multiple tower cranes need to be purchased, which is not conducive to cost control; when using the crane hoisting method, after the materials are lifted, the materials will be inclined and still need to be corrected manually to complete the docking, which greatly reduces the construction efficiency.

[0034] Next, the technical solutions in the embodiments of the present invention will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments.

[0035] Please refer to Figures 1 to 6 , as an embodiment of the present invention, the material loading device for bridge construction includes a frame 1 and a plurality of telescopic sleeve columns 6 rotatably arranged on the frame 1. A telescopic column 7 is slidably fitted inside the telescopic sleeve column 6; a material platform 8 is rotatably arranged on a plurality of the telescopic columns 7;

[0036] A deflection mechanism is arranged on the frame 1, and the deflection mechanism can increase or decrease the included angle between the telescopic sleeve column 6 and the frame 1; so as to increase or decrease the distance between the material platform 8 and the frame 1;

[0037] A telescopic mechanism is arranged on the frame 1, and the telescopic mechanism can drive the telescopic column 7 to slide along the length direction of the telescopic sleeve column 6 when the deflection mechanism acts, so as to further increase the distance between the material platform 8 and the frame 1.

[0038] In this embodiment, first, the materials are transferred to the material platform 8, and the material platform 8 is moved from the stockpile to the construction area by moving the frame 1.

[0039] The telescopic sleeve column 6 is driven to rotate by a deflection mechanism to increase the angle between the telescopic sleeve column 6 and the vehicle frame 1, so as to increase the distance between the material table 8 and the vehicle frame 1, and make the material table 8 close to the construction area.

[0040] At the same time, the telescopic column 7 is driven to slide in and out of the telescopic sleeve column 6 by a telescopic mechanism to further increase the distance between the material table 8 and the vehicle frame 1, so that the material table 8 and the processing area are at the same horizontal height, which is convenient for unloading materials and docking with the processing part.

[0041] Through the mutual cooperation of the telescopic mechanism and the deflection mechanism, the material can be transferred from the stacking area with a relatively low horizontal height to the construction area with a relatively high height. And during the transfer process, the material always keeps parallel and close to the construction area, which is convenient for unloading and improves the accuracy of material docking.

[0042] As a further solution of the present utility model, a second rotating shaft 9 and two third rotating shafts 10 are rotatably installed on the vehicle frame 1; the second rotating shaft 9 is connected to the two third rotating shafts 10 respectively through belts; both ends of the third rotating shaft 10 are rotatably installed with the telescopic sleeve column 6, and the two telescopic sleeve columns 6 are fixedly connected through a connecting rod 601.

[0043] In this embodiment, when the deflection mechanism drives the telescopic sleeve column 6 to rotate on one third rotating shaft 10, at this time, the telescopic sleeve column 6 on this third rotating shaft 10 will act on the telescopic sleeve column 6 on the other third rotating shaft 10 through the material table 8 to make it rotate; and during the rotation process, the telescopic sleeve columns 6 on the two third rotating shafts 10 always remain relatively parallel, that is, the angles between the telescopic sleeve columns 6 on the two third rotating shafts 10 and the material table 8 are always the same; in the initial state, the material table 8 is parallel to the vehicle frame 1, so the material table 8 always remains parallel to the vehicle frame 1 during the operation of the deflection mechanism. Therefore, when transferring the material from the stockyard to directly below the construction bridge, only need to ensure that the vehicle frame 1 is parallel to the construction area of the construction bridge, and the material will always be parallel to the construction area during the rising process; which is convenient for unloading and improves the accuracy of material docking.

[0044] The connecting rod 601 can make the two telescopic sleeve columns 6 on the same third rotating shaft 10 rotate synchronously. When the second rotating shaft 9 rotates, it will drive the two third rotating shafts 10 to rotate through the belt, thereby indirectly driving the telescopic mechanism to act, so that the telescopic mechanism and the deflection mechanism can act synchronously to ensure that the material can be stably lifted to the construction area.

[0045] As a further solution of the present utility model, the deflection mechanism includes a motor 2 fixedly installed on the vehicle frame 1, and a first rotating shaft 3 fixedly connected to the output end of the motor 2 and rotatably connected to the vehicle frame 1; a screw rod column 301 is fixedly connected to the first rotating shaft 3, and an internally threaded sleeve 4 is threadedly connected to the screw rod column 301; a connecting rod 5 rotatably installed on the internally threaded sleeve 4 and rotatably connected to the connecting rod 601 is provided.

[0046] In this embodiment, in the initial state, there is a small included angle between the connecting rod 5 and the internally threaded sleeve 4. When the motor 2 rotates, it will drive the first rotating shaft 3 to rotate, thereby driving the screw rod column 301 to rotate. Through the threaded cooperation with the internally threaded sleeve 4, the internally threaded sleeve 4 gradually moves away from the motor 2, and the included angle between the connecting rod 5 and the internally threaded sleeve 4 will gradually increase during the moving-away process, and the included angle between the connecting rod 5 and the connecting rod 601 will also gradually increase, thereby pushing the telescopic sleeve column 6 to rotate on the third rotating shaft 10, and the included angle between the telescopic sleeve column 6 and the vehicle frame 1 will gradually increase; making the material table 8 approach the construction area.

[0047] As a further solution of the present utility model, a worm column 302 is fixedly installed at one end of the screw rod column 301 away from the motor 2, and a worm gear 901 meshing with the worm column 302 is fixedly installed on the second rotating shaft 9.

[0048] In this embodiment, the rotating screw rod column 301 will drive the worm column 302 to rotate, and drive the second rotating shaft 9 to rotate through the meshing action with the worm gear 901, thereby driving the third rotating shaft 10 to rotate to drive the telescopic mechanism to act; enabling the telescopic mechanism and the deflection mechanism to act synchronously to ensure that the material can be stably lifted to the construction area.

[0049] As a further solution of the present utility model, the telescopic mechanism includes a fourth rotating shaft 11 rotatably installed on the telescopic sleeve column 6, and the fourth rotating shaft 11 is connected to the third rotating shaft 10 through a belt; a gear 1101 is fixedly installed on the fourth rotating shaft 11; a tooth groove 701 meshing with the gear 1101 is provided on the telescopic column 7.

[0050] In this embodiment, when the third rotating shaft 10 rotates, it will drive the fourth rotating shaft 11 through the belt, thereby driving the gear 1101 to rotate. Through the meshing action between the gear 1101 and the tooth groove 701, the telescopic column 7 slides in and out of the telescopic sleeve column 6, thereby lifting the material table 8 to further increase the distance between the material table 8 and the vehicle frame 1, so that the material table 8 and the processing area are at the same horizontal height. To facilitate the unloading of materials and the docking with the processing part.

[0051] As a further solution of the present utility model, a guide rail is fixedly installed on the material table 8, and a slider is slidably fitted on the guide rail.

[0052] In this embodiment, the material is placed on the slider, and the slider slides on the guide rail to transfer the material from the material table 8, saving manpower and improving the construction efficiency at the same time.

[0053] As a further solution of the present utility model, wheels are rotatably installed on the vehicle frame 1, and the outer surface of the wheels has a relatively large coefficient of friction.

[0054] In this embodiment, since bridge construction is mostly carried out in areas with relatively rough terrain, the coefficient of friction of the wheels is increased to improve the stability during the feeding process, reduce the probability of vehicle slipping, and improve the construction safety.

[0055] The above embodiments are exemplary rather than restrictive. Therefore, without departing from the spirit or basic characteristics of the present utility model, all technical solutions that can implement the present utility model in other specific forms are included in the present utility model.
