Description

Technical Field

[0001] This utility model relates to the technical field of bridge-type sand suction machine, specifically to a bridge-type sand suction machine with a sand suction pump lifting and lowering function. Background Technology

[0002] A bridge-type sand suction machine with sand suction pump lifting and lowering function is usually designed for the removal of sand or other sediments in underwater engineering. This type of equipment is often used for dredging operations in water bodies such as rivers, lakes, and ports. Its key feature is that it can accurately control the sand suction depth in the water body and has lifting and lowering function to adapt to the needs of different water depths and working environments.

[0003] According to a public announcement (publication number: CN120037700A), a bridge-type sand suction machine with sand suction pump lifting and lowering function includes a traveling beam and a sand suction pump. Two sets of symmetrically arranged fixed plates are fixedly installed at the bottom of the traveling beam, and a movable plate that moves laterally at the bottom of the traveling beam is arranged between the two fixed plates. Two first electric push rods are fixedly installed at the bottom of the two movable plates respectively. The bottom of the two first electric push rods are fixedly installed together with a mounting frame. Two symmetrically arranged sliding grooves are opened on the mounting frame.

[0004] The coordination between the aforementioned components, such as the traveling beam and the sand suction pump, makes it difficult to ensure that the bridge-type sand suction machine can adapt to different aquatic environments, resulting in an inability to guarantee efficient operation at different water depths, which needs to be improved. Utility Model Content

[0005] This utility model proposes a bridge-type sand suction machine with sand suction pump lifting and lowering function.

[0006] The technical solution of this utility model is as follows: A bridge-type sand suction machine with a sand suction pump lifting and lowering function includes a bridge-type sand suction machine. A base plate is provided on the top of the bridge-type sand suction machine. A lifting and lowering assembly is provided on the top of the bridge-type sand suction machine. The lifting and lowering assembly includes a rectangular groove, which is opened at the bottom of the bridge-type sand suction machine. A sand suction pump is fixedly connected to the top of the base plate. A sand suction pipe passes through the side of the sand suction pump. A support frame is fixedly connected to the top of the bridge-type sand suction machine. A motor is fixedly connected to the inner wall of the support frame. A gear is fixedly connected to the output shaft of the motor. A rack is slidably connected to the inner wall of the support frame. A connecting rod is fixedly connected to the side of the rack. The end of the connecting rod away from the rack is fixedly connected to the bottom of the base plate.

[0007] The rack and gear mesh with each other, and the top of the support frame has a slot located on the displacement trajectory of the rack. This design is beneficial for the rack to move when the gear rotates.

[0008] The bottom of the bridge-type sand suction machine is equipped with pulleys, and a limit rod is fixedly connected to the side of the rack. The end of the limit rod away from the rack is slidably connected to the inner wall of the support frame. The design of the limit rod helps to restrict the movement trajectory of the rack and prevent the rack from deviating from its movement trajectory.

[0009] The support frame and connecting rods are provided in two symmetrical configurations along the vertical central axis of the bridge-type sand suction machine. The two connecting rods facilitate the stable movement of the base plate and the sand suction pump.

[0010] The bridge-type sand suction machine is equipped with an anti-clogging and jamming component on its side. The anti-clogging and jamming component includes a telescopic extrusion rod, one end of which is fixedly connected to the side of a connecting rod. A round rod is fixedly connected to the side of the bridge-type sand suction machine, and a bracket is fixedly connected to one end of the round rod. A turntable is rotatably connected to the inner wall of the bracket. An inclined rod is fixedly connected to the circumference of the turntable, and a striking rod is fixedly connected to the top of the inclined rod. The striking rod strikes the outer wall of the sand suction pipe, reducing the possibility of blockage.

[0011] The inclined rod is located on the displacement trajectory of the telescopic extrusion rod, and the striking rod is located at the bottom of the sand suction pipe. This design is beneficial because the inclined rod can be directly squeezed when the telescopic extrusion rod moves.

[0012] The sand suction tube is located on the displacement trajectory of the striking rod, and the telescopic squeezing rod is located on the side of the sand suction tube. This design is beneficial for striking the surface of the sand suction tube when the striking rod moves, causing it to vibrate.

[0013] A short rod is fixedly connected to the bottom of the bracket, and a spring is fixedly connected to the top of the short rod. The end of the spring away from the short rod is fixedly connected to the bottom of the inclined rod. The design of the spring is conducive to the inclined rod automatically returning to its original position when it is not compressed.

[0014] The working principle and beneficial effects of this utility model are as follows:

[0015] 1. This utility model achieves precise adjustment of the vertical position of the sand suction pump through the mutual cooperation between components such as rack, motor, gear, and connecting rod inside the lifting assembly. This is achieved by driving the gear, rack, and connecting rod with the motor. This allows the bridge-type sand suction machine to adapt to different water environments and bottom conditions, ensuring efficient operation at different water depths. The long suction pipe design ensures that the sand suction pump can effectively suck up the sediment at the bottom, reducing the distance between the sand suction pump and the sediment at the bottom and improving the sand suction effect. At the same time, the long suction pipe also increases the flexibility of the system and can better adapt to complex underwater environments.

[0016] 2. This utility model utilizes the interplay between components such as the striking rod and telescopic squeezing rod within the anti-clogging and jamming assembly. The striking rod strikes the outer wall of the sand suction pipe, effectively reducing blockage. This vibration loosens sediment or foreign objects within the pipe, preventing blockage and ensuring the normal operation of the sand suction pump. Regularly vibrating and cleaning the pipe wall prevents excessive accumulation of sand and sediment, reducing equipment wear and blockage and extending the service life of the sand suction machine.

[0017] Of course, any product implementing this utility model does not necessarily need to achieve all of the advantages described above at the same time. Attached Figure Description

[0025] The technical solutions of this utility model will be clearly and completely described below with reference to the embodiments of this utility model. Obviously, the described embodiments are only some embodiments of this utility model, and not all embodiments. Based on the embodiments of this utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the scope of protection of this utility model.

[0026] Example 1

[0027] like Figures 1-5 As shown, this embodiment proposes a bridge-type sand suction machine with a sand suction pump lifting and lowering function, including a bridge-type sand suction machine 1. A base plate 2 is provided on the top of the bridge-type sand suction machine 1. A lifting and lowering assembly 3 is provided on the top of the bridge-type sand suction machine 1. The lifting and lowering assembly 3 includes a rectangular groove 31, which is opened at the bottom of the bridge-type sand suction machine 1. A sand suction pump 33 is fixedly connected to the top of the base plate 2. A sand suction pipe 34 passes through the side of the sand suction pump 33. A support frame 35 is fixedly connected to the top of the bridge-type sand suction machine 1. A motor 36 is fixedly connected to the inner wall of the support frame 35. A gear 37 is fixedly connected to the output shaft of the motor 36. A rack 38 is slidably connected to the inner wall of the support frame 35. A connecting rod 39 is fixedly connected to the side of the rack 38. The end of the connecting rod 39 away from the rack 38 is fixedly connected to the bottom of the base plate 2.

[0028] The rack 38 and the gear 37 mesh with each other. The top of the support frame 35 has a slot 311, which is located on the displacement trajectory of the rack 38. This design is beneficial to drive the rack 38 to move when the gear 37 rotates.

[0029] The bottom of the bridge-type sand suction machine 1 is equipped with a pulley 312, and a limit rod 310 is fixedly connected to the side of the rack 38. The end of the limit rod 310 away from the rack 38 is slidably connected to the inner wall of the support frame 35. The design of the limit rod 310 is conducive to limiting the movement trajectory of the rack 38 and preventing deviation of the movement trajectory of the rack 38.

[0030] There are two support frames 35 and two connecting rods 39, which are symmetrical to each other along the vertical central axis of the bridge-type sand suction machine 1. The two connecting rods 39 are conducive to the stable movement of the base plate 2 and the sand suction pump 33.

[0031] In this embodiment, the sand suction pump 33 is located at the top of the bridge-type sand suction machine 1. When the position of the sand suction pump 33 needs to be adjusted, the motor 36 is started. The rotation of the motor 36 drives the gear 37 to rotate. The gear 37 and the rack 38 mesh with each other. The rotation of the gear 37 drives the rack 38 to move. The movement of the rack 38 drives the connecting rod 39 to move, causing the connecting rod 39 to slide on the side of the bridge-type sand suction machine 1. The rectangular groove 31 is located on the movement trajectory of the connecting rod 39. When the motor 36 rotates forward, it drives the gear 37 to rotate forward, causing the rack 38 to move upward. The upward movement of the rack 38 drives the connecting rod 39 to move upward. The upward movement of the connecting rod 39 drives the base plate 2, the sand suction pump 33, and the sand suction pipe 34 to move upward, adjusting the position of the sand suction pump 33. When downward adjustment is needed, the motor 36 is started, causing the motor 36 to rotate in reverse. The reverse rotation of the motor 36 drives the gear 37 to rotate in reverse, causing the gear 37 to drive the rack 38 to move downward. Moving bar 38 downwards will cause connecting rod 39 to move downwards, allowing the originally rising bottom plate 2 and sand suction pump 33 to move downwards. However, sand suction pump 33 will always remain at the top of bridge sand suction machine 1 and will not detach from it. The sand suction pipe 34 is designed to be relatively long for easy sand suction. Sand suction pump 33 can be adjusted according to changes in water depth and bottom conditions. Through the mechanism of motor 36 driving gear 37, rack 38 and connecting rod 39, the vertical position of sand suction pump 33 can be precisely adjusted. This allows bridge sand suction machine 1 to adapt to different water environments and bottom conditions, ensuring efficient operation at different water depths. The long design of sand suction pipe 34 ensures that sand suction pump 33 can effectively suck up bottom sediment, reducing the distance between sand suction pump 33 and bottom sediment, improving sand suction effect. At the same time, the long sand suction pipe 34 also increases the flexibility of the system and can better adapt to complex underwater environments.

[0032] Example 2

[0033] like Figures 1-5 As shown, based on the same concept as in Embodiment 1 above, the bridge-type sand suction machine 1 is provided with an anti-clogging and jamming component 4 on its side. The anti-clogging and jamming component 4 includes a telescopic extrusion rod 41. One end of the telescopic extrusion rod 41 is fixedly connected to the side of the connecting rod 39. A round rod 42 is fixedly connected to the side of the bridge-type sand suction machine 1. One end of the round rod 42 is fixedly connected to a bracket 43. A turntable 44 is rotatably connected to the inner wall of the bracket 43. An inclined rod 45 is fixedly connected to the circumference of the turntable 44. A striking rod 46 is fixedly connected to the top of the inclined rod 45. The striking rod 46 strikes the outer wall of the sand suction pipe 34 to reduce the possibility of blockage of the sand suction pipe 34.

[0034] The inclined rod 45 is located on the displacement trajectory of the telescopic extrusion rod 41, and the striking rod 46 is located at the bottom of the sand suction pipe 34. This design is beneficial to the fact that the inclined rod 45 can be directly extruded when the telescopic extrusion rod 41 moves.

[0035] The suction pipe 34 is located on the displacement trajectory of the striking rod 46, and the telescopic extrusion rod 41 is located on the side of the suction pipe 34. This design is beneficial to strike the surface of the suction pipe 34 when the striking rod 46 moves, so that it vibrates.

[0036] A short rod 47 is fixedly connected to the bottom of the bracket 43, and a spring 48 is fixedly connected to the top of the short rod 47. The end of the spring 48 away from the short rod 47 is fixedly connected to the bottom of the inclined rod 45. The design of the spring 48 is conducive to the automatic reset of the inclined rod 45 when it is not compressed.

[0037] In this embodiment, the upward movement of the connecting rod 39 causes the telescopic extrusion rod 41 to move upward. The telescopic extrusion rod 41 is electrically operated. When it moves upward, it presses against the inclined rod 45, which is located on the trajectory of the telescopic extrusion rod 41. The telescopic extrusion rod 41 presses the inclined rod 45 upward, causing the turntable 44 to rotate upward. This rotation of the turntable 44 then causes the striking rod 46 to move upward. The striking rod 46 is located on the trajectory of the suction pipe 34. When the striking rod 46 moves upward, it strikes the outer wall of the suction pipe 34, impacting the suction pipe. The vibration of the sand suction pipe 34 reduces the possibility of blockage. When it is not necessary to knock to prevent blockage, the telescopic squeezing rod 41 can be retracted to prevent it from continuously squeezing the inclined rod 45 and affecting the up and down movement of the connecting rod 39. By knocking the outer wall of the sand suction pipe 34 with the knocking rod 46, the blockage of the sand suction pipe 34 can be effectively reduced. This vibration can loosen the sediment or foreign objects in the pipe, thereby preventing the blockage of the sand suction pipe 34 and maintaining the normal operation of the sand suction pump 33. By regularly vibrating and cleaning the pipe wall, excessive accumulation of sand and sediment can be prevented, thereby reducing the wear and blockage of the equipment and extending the service life of the sand suction machine.

[0038] The above are merely preferred embodiments of the present utility model and are not intended to limit the present utility model. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model shall be included within the protection scope of the present utility model.
