Description

Technical Field

[0001] The utility model relates to the technical field of engineering equipment, in particular to a stirring device for bridge construction. Background Art

[0002] In the field of construction engineering, the emergence of cement mixing devices is to meet the ever-increasing requirements for cement mixing efficiency and quality. With the continuous development of the modern construction industry, all kinds of construction projects require a reliable material foundation. Cement mixing devices have greatly improved the speed and uniformity of cement mixing. They are widely used in many fields such as housing construction, roads and bridges, and water conservancy projects. In housing construction, they can mix concrete for pouring walls, floor slabs and other structures; in road construction, they can provide high-quality cement-stabilized gravel and other materials for paving roads; in water conservancy projects, they mix concrete for the construction of hydraulic structures such as dams and sluices.

[0003] In the specific field of bridge construction, traditional mixing devices often have problems such as uneven mixing and low efficiency, making it difficult to meet the demand for high-quality concrete. Against this background, flat-top mixing devices came into being. Their unique design structure gives them obvious advantages in bridge construction, ensuring more uniform mixing of concrete and improving the strength and durability of concrete. During the construction of bridge piers, bridge decks and other parts, flat-top mixing devices can provide high-quality concrete for the project, ensuring the safety and service life of the bridge structure. At the same time, their stable performance and efficient mixing capacity also speed up the progress of bridge construction and reduce project costs.

[0004] However, the existing equipment still has certain shortcomings. The transmission belt of this equipment is dangerous when used and may cause personal injury when running at high speed. At present, the protective cover is installed with bolts for protection, but it is difficult to disassemble, which is not conducive to the repair of transmission belt failures, increases the maintenance time cost and may damage components. Frequent disassembly and installation will also cause the bolts to loosen and reduce the protection effect. How to ensure safety and improve the convenience of disassembly of the protective cover is an urgent problem to be solved. Utility Model Content

[0005] Based on this, the purpose of the present invention is to provide a mixing device for bridge construction to solve the technical problems mentioned in the above background technology.

[0006] To achieve the above-mentioned object, the present invention provides the following technical solution: a mixing device for bridge construction, comprising a mixing equipment body and a support frame, an engine being fixedly mounted on the front outer wall of the support frame, a protective assembly being mounted on the outer wall of the support frame near the position of the engine, and support assemblies being fixedly mounted on the outer sides of both sides of the support frame;

[0007] The protective assembly includes multiple groups of connecting blocks welded to the outer wall of the supporting frame, and the outer wall of each group of the connecting blocks is provided with a through groove, and the inner wall of the through groove is slidably sleeved with a clamping rod, the outer wall of the clamping rod is fixedly connected to the limiting ring, and the outer wall of the clamping rod is sleeved with a spring, and the two ends of the spring are respectively fixed to the outer wall of the side where the connecting block and the limiting ring are close to each other, and a protective cover is movably installed in the middle position of the multiple groups of the connecting blocks.

[0008] By adopting the above technical solution, the card slot on the protective cover is first aligned with the card rod and pressed. At this time, multiple card rods are squeezed and retracted at the same time. At the same time, the spring is squeezed to prepare for the card rod to reset. When the card rod moves to the corresponding card slot, the spring drives the card rod to rebound and insert into the corresponding card slot, thereby realizing the rapid fixation of the protective cover. When disassembling, you only need to pinch the pinch block and do the opposite of the above operation, then first lift one side of the protective cover, and then the other side and repeat this process to achieve the rapid disassembly of the protective cover.

[0009] Furthermore, one end of the clamping rod close to the protective cover is sharp, and the other end of the clamping rod is fixedly connected to a pinch.

[0010] By adopting the above technical solution, the sharp end of the card rod cooperates with the card slot and can be squeezed inward when the protective cover is installed. When it is aligned with the card slot, it automatically pops out and is inserted into the card slot for fixation, thereby realizing rapid fixation of the protective cover. Pinch quickly to facilitate pulling the card rod outward to contact the limit. After pulling out the two groups of card rods on one side of the protective cover from the card slot to release the limit, it is necessary to lift one side of the protective cover, and then lift the other side to complete the disassembly.

[0011] Furthermore, the sharp end of the clamping rod extends into the interior of the protective cover, and a clamping groove is provided at the contact position between the protective cover and the clamping rod.

[0012] By adopting the above technical solution, the card slot matching the card rod can facilitate the insertion of the card rod to limit and fix the protective cover.

[0013] Furthermore, the support assembly includes a lifting cylinder fixedly connected to the outer walls of the support frame. The interior of each group of the lifting cylinders is fixedly connected to a connecting seat. The inner center position of the lifting cylinder is rotatably connected to a threaded rod, and the outer wall of the threaded rod is rotatably connected to the connecting seat.

[0014] By adopting the above technical solution, the connecting seat can provide a reinforcing support for the threaded rod, thereby preventing the threaded rod from deviating and causing the lifting legs to get stuck.

[0015] Furthermore, the lifting cylinder has a lifting foot slidingly sleeved inside, and the lifting foot is threadedly connected to the threaded rod. A thread groove of matching size is provided at the contact point between the lifting foot and the threaded rod, and a pad is fixedly connected to the outer wall of the bottom end of the lifting foot.

[0016] By adopting the above technical solution, the pad can increase the contact area with the ground, increase friction, and improve the stability of equipment use.

[0017] Furthermore, a second bevel gear is fixedly connected to the axial center position of the top end of the threaded rod, and a rotating rod is rotatably connected to the outer walls of the two groups of lifting cylinders.

[0018] By adopting the above technical solution, the rotation of the rotating rod drives the two sets of second bevel gears to synchronously engage with the first bevel gear and the threaded rod, and then synchronously drives the two sets of lifting legs to perform lifting operations, thereby improving operating efficiency.

[0019] Furthermore, the outer wall of the rotating rod is located inside the two sets of lifting cylinders and is symmetrically fixedly connected to the first bevel gear, and the first bevel gear is meshed with the second bevel gear. One end of the rotating rod is fixedly connected to the hexagonal nut sleeve.

[0020] By adopting the above technical solution, the hexagonal nut sleeve can facilitate the rotation of the rotating rod while reducing the occupied space.

[0021] In summary, the present invention has the following beneficial effects:

[0022] The utility model first aligns the slot on the protective cover with the card rod and presses it, so that the card rod is squeezed and retracted. When the card rod moves into the corresponding slot, the spring drives the card rod to rebound and insert into the corresponding slot, so as to achieve rapid fixation of the protective cover. When disassembling, it is only necessary to pinch the pinching block and perform the above operation in reverse, and then gradually lift the two sides of the protective cover to achieve rapid disassembly of the protective cover. Then, the rotating rod is rotated, and the first bevel gear and the second bevel gear are engaged to simultaneously drive the two sets of threaded rods to rotate, thereby simultaneously driving the two sets of lifting legs to rise and fall synchronously, thereby increasing the lifting speed of the lifting legs.

[0029] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. The embodiments described below with reference to the drawings are exemplary and are only used to explain the present invention, and cannot be understood as limiting the present invention.

[0030] The following describes an embodiment of the present invention based on its overall structure.

[0031] A mixing device for bridge construction, such as Figure 1 - Figure 5 As shown, it includes a mixing equipment body 1 and a support frame 11. An engine 12 is fixedly mounted on the front outer wall of the support frame 11. A protective component 2 is mounted on the outer wall of the support frame 11 near the engine 12. Support components 3 are fixedly mounted on both sides of the support frame 11.

[0032] The protective component 2 includes multiple groups of connecting blocks 21 welded to the outer wall of the support frame 11. The outer wall of each group of connecting blocks 21 is provided with a through groove 211. The inner wall of the through groove 211 is slidably sleeved with a clamping rod 22. The outer wall of the clamping rod 22 is fixedly connected to a limiting ring. The outer wall of the clamping rod 22 is sleeved with a spring 23. The two ends of the spring 23 are respectively fixed to the outer wall of the side close to the connecting block 21 and the limiting ring. A protective cover 24 is movably installed in the middle position of the multiple groups of connecting blocks 21.

[0033] By first holding the protective cover 24 and aligning the slots 241 with the multiple card rods 22 and pressing them, the multiple card rods 22 are squeezed and retracted at the same time, and the springs 23 are squeezed to prepare for the reset of the card rods 22. When the card rods 22 move into the corresponding slots 241, the springs 23 drive the card rods 22 to rebound and insert into the corresponding slots 241, thereby quickly fixing the protective cover 24. When disassembling, you only need to pinch the pinching block and do the opposite of the above operation, then first lift one side of the protective cover 24, and then the other side, and repeat this process to achieve quick disassembly of the protective cover 24.

[0034] See also Figure 2 - Figure 4The end of the card rod 22 close to the protective cover 24 is sharp, and the other end of the card rod 22 is fixedly connected with a pinch 221. By setting the above structure, the utility model can cooperate with the card slot 241 to be squeezed and retracted when the protective cover 24 is installed. When it is aligned with the card slot 241, it automatically pops out and inserts into the card slot 241 for fixation, thereby realizing rapid fixation of the protective cover 24. The pinch 221 can facilitate the card rod 22 to be pulled outward to contact the limit. After the multiple groups of two groups of card rods 22 on one side of the protective cover 24 are pulled out of the card slot 241 to release the limit, it is necessary to lift one side of the protective cover 24, and then lift the other side to complete the disassembly.

[0035] See also Figure 2 - Figure 4 The sharp end of the card rod 22 extends to the inside of the protective cover 24, and a card slot 241 is provided at the contact position between the protective cover 24 and the card rod 22. By setting the above structure, the card slot 241 matching the card rod 22 can facilitate the insertion of the card rod 22 to limit and fix the protective cover 24.

[0036] See also Figure 5 The support assembly 3 includes a lifting cylinder 31 fixedly connected to the outer walls of the support frame 11. The interior of each group of lifting cylinders 31 is fixedly connected to a connecting seat 311. The inner center position of the lifting cylinder 31 is rotatably connected to a threaded rod 34, and the outer wall of the threaded rod 34 is rotatably connected to the connecting seat 311. By setting the above structure, the utility model can strengthen the support of the threaded rod 34 and prevent the threaded rod 34 from deviating and causing the lifting leg 32 to get stuck.

[0037] See also Figure 5 The lifting cylinder 31 has a lifting foot 32 which is slidably sleeved inside, and the lifting foot 32 is threadedly connected to the threaded rod 34. A threaded groove 321 of matching size is provided at the contact point between the lifting foot 32 and the threaded rod 34. The outer wall of the bottom end of the lifting foot 32 is fixedly connected to a pad 322. By setting the above structure, the pad 322 can increase the contact area with the ground, increase friction, and improve the stability of the equipment.

[0038] See also Figure 5 The second bevel gear 341 is fixedly connected to the top axial position of the threaded rod 34, and the outer walls of the two sets of lifting cylinders 31 are rotatably connected with the rotating rod 33. By setting the above structure, the utility model drives the two sets of second bevel gears 341 to synchronously engage the first bevel gear 331 and the threaded rod 34 through the rotation of the rotating rod 33, and then synchronously drives the two sets of lifting legs 32 to perform lifting operations, thereby improving operating efficiency.
