Description

Technical Field

[0001] This utility model relates to the field of water conservancy construction technology, and in particular to a hoist for water conservancy construction. Background Technology

[0002] Water conservancy construction is an engineering construction process that takes water conservancy projects (such as reservoirs, irrigation areas, and dikes) as its objects and comprehensively utilizes civil engineering technology, water resource management methods, and intelligent means to achieve functions such as flood control, irrigation, water supply, and power generation.

[0003] In water conservancy construction, it is necessary to excavate foundation pits. Due to the presence of water systems around some foundation pits, water may accumulate inside the pits. Therefore, water pumps are needed to remove the water. Traditionally, water pumps are manually lowered into the foundation pits. However, the depth of the foundation pits varies, and manual entry poses certain dangers. Based on this, a hydraulic construction hoist is proposed. By setting up a lifting mechanism, it can replace manual labor to lower water pumps into the foundation pits for water pumping operations. Utility Model Content

[0004] The purpose of this utility model is to overcome the shortcomings of the prior art and provide a hoist for water conservancy construction, which effectively solves the deficiencies of the prior art.

[0005] To achieve the above objectives, one embodiment of this utility model provides a hydraulic construction hoist, including a transport platform. A hydraulic cylinder is rotatably mounted on the center of the top surface of the transport platform. A support frame is rotatably mounted on one end of the transport platform. A connecting rod is fixedly mounted on one side of the end of the support frame, and one end of the connecting rod is rotatably connected to the output end of the hydraulic cylinder. Two first guide rails and two second guide rails arranged in parallel are mounted on one side of the support frame, and a moving platform is slidably mounted on all four of them. A water pump is fixedly mounted on one side of the moving platform.

[0006] Preferably, in any of the above schemes, multiple counterweights and containers are installed on the side of the transport platform away from the top surface of the support frame. In this scheme, the counterweights facilitate the balancing of the weight of the support frame, improving the overall stability and safety, while the containers provide a storage function, making it convenient to store hoses, etc., and to connect the hoses to pump out seepage water inside the pit.

[0007] Preferably, in any of the above embodiments, the support frame is hollowed out in the middle, and both corners of one end of the support frame are rotatably connected to one side of the top surface of the transport platform by pins. Baffles are installed at the ends of the support frame near the first and second guide rails. In this embodiment, the hollow design of the support frame can reduce its relative weight while ensuring its structural strength. It is convenient for the support frame to rotate at a certain angle under the action of the hydraulic cylinder, so that the water pump can enter the water and facilitate the drainage of seepage water inside the foundation pit. The baffles can limit the movement position of the moving platform and prevent the moving platform from sliding out of the first and second guide rails.

[0008] Preferably, in any of the above embodiments, sprockets are rotatably connected to the middle of both ends of the support frame, and chains are meshed together on the outer walls of both. A reduction motor is fixedly connected to one side of the top of the support frame, and its output end is fixedly connected to a sprocket. The middle of the chain is fixedly connected to the end of the moving platform. This embodiment facilitates the operation of the reduction motor by powering it on, driving one sprocket to rotate, and completing the traction of the moving platform by the meshing of the chain with the two sprockets. This facilitates the movement of the moving platform along the length of the first guide rail, adjusting the placement height of the water pump, and keeping the water pump inlet as far away as possible from the mud and sand at the bottom of the pit, thus facilitating the pumping out of accumulated water.

[0009] Preferably, in any of the above solutions, two connecting collars are installed in the middle of the side of the moving platform, and the two collars are clamped to the outer wall of the water pump. In this solution, both connecting collars adopt a semi-ring design and are fixedly connected to each other by fasteners to fix the water pump. One end of the moving platform is fixedly connected to the chain, and the chain drives the moving platform to move, which facilitates the height adjustment of the moving platform and the water pump.

[0010] Preferably, in any of the above solutions, rollers are rotatably mounted at each of the four corners of the mobile platform, and the four rollers are respectively installed inside the two first guide rails and the two second guide rails. By using this solution, the four corners of the mobile platform can be positioned between the first guide rails and the second guide rails, and the rollers are rotatably mounted inside the first guide rails and the second guide rails, thereby limiting the installation position of the mobile platform.

[0011] This utility model has the following advantages:

[0012] 1. This type of hydraulic construction hoist, by setting up a transport platform and a support frame, with the support frame driven by a hydraulic cylinder to rotate relative to the transport platform, facilitates the control of one end of the support frame to rotate into the interior of the foundation pit. By setting up two first guide rails and a second guide rail, it is easy to push the moving platform and water pump along the length of the first guide rail. When the support frame is in a horizontal state, the moving platform is positioned at the end of the support frame away from the transport platform. After the support frame rotates into the foundation pit, the water pump enters the water, thereby avoiding the need for manual entry into the foundation pit and preventing dangerous situations. The overall structure is simple and effectively solves the problems existing in the prior art.

[0013] 2. This type of hydraulic construction hoist is equipped with two sprockets, a chain, and a reduction motor. The output end of the reduction motor is fixedly connected to one of the sprockets, and the chain is fixedly connected to one side of the moving platform. When the reduction motor is powered on, the sprockets rotate, causing the moving platform to move along the first and second guide rails. This facilitates the adjustment of the placement height of the water pump in the foundation pit, prevents the water pump from sucking in mud and sand, and ensures smooth drainage.

Detailed Implementation

[0019] The present invention will be further described below with reference to the accompanying drawings, but the scope of protection of the present invention is not limited to the following description.

[0020] like Figures 1 to 4As shown, a hydraulic construction hoist includes a transport platform 1. A hydraulic cylinder 4 is rotatably mounted on the center of the top surface of the transport platform 1. A support frame 11 is rotatably mounted on one end of the transport platform 1. A connecting rod 13 is fixedly mounted on one side of the end of the support frame 11, and one end of the connecting rod is rotatably connected to the output end of the hydraulic cylinder 4. Two first guide rails 5 and two second guide rails 10 arranged in parallel are mounted on one side of the support frame 11. A moving platform 9 is slidably mounted on all four of them. A water pump 7 is fixedly mounted on one side of the moving platform 9. The moving platform 9 has a hollow design, which can reduce its relative weight while ensuring its structural strength. The first guide rails 5 and the second guide rails 10 are placed in parallel, and their sides are fixedly connected to the support frame 11 by bolts.

[0021] Multiple counterweights 2 and a container 3 are installed on the side of the transport platform 1 away from the top surface of the support frame 11. As an optional technical solution of this utility model, the counterweights 2 are used to balance the weight of the support frame 11, thereby improving the overall stability and safety. The container 3 provides a holding function, making it convenient to store hoses and other materials, and to connect hoses to pump out seepage water inside the pit.

[0022] The support frame 11 is hollow in the middle. The two corners of one end of the support frame 11 are rotatably connected to one side of the top surface of the transport platform 1 by pins. The ends of the support frame 11 near the first guide rail 5 and the second guide rail 10 are equipped with baffles. As an optional technical solution of this utility model, the hollow design of the support frame 11 can reduce its relative weight while ensuring its structural strength. It is convenient for the support frame 11 to rotate at a certain angle under the action of the hydraulic cylinder 4, so that the water pump 7 can enter the water and facilitate the drainage of seepage water inside the foundation pit. The baffles can limit the movement position of the moving platform 9 and prevent the moving platform 9 from sliding out of the first guide rail 5 and the second guide rail 10.

[0023] Both ends of the support frame 11 are rotatably connected to the middle of a sprocket 14, and the outer walls of both are meshed with a chain 6. A reduction motor 12 is fixedly connected to one side of the top of the support frame 11, and its output end is fixedly connected to a sprocket 14. The middle of the chain 6 is fixedly connected to the end of the moving platform 9. As an optional technical solution of this utility model, this facilitates the operation of the reduction motor 12 when it is powered on, driving one sprocket 14 to rotate. The chain 6 meshes with the two sprockets 14 to complete the traction of the moving platform 9, which facilitates the movement of the moving platform 9 along the length of the first guide rail 5. The placement height of the water pump 7 is adjusted so that the inlet of the water pump 7 is as far away from the mud and sand at the bottom of the pit as possible, which facilitates the pumping out of the accumulated water.

[0024] Two connecting collars 8 are installed in the middle of the side of the moving platform 9. The two collars are clamped to the outer wall of the water pump 7. As an optional technical solution of this utility model, both connecting collars 8 adopt a semi-ring design and are fixedly connected to each other by fasteners to fix the water pump 7. One end of the moving platform 9 is fixedly connected to the chain 6, and the chain 6 drives the moving platform 9 to move, which facilitates the height adjustment of the moving platform 9 and the water pump 7.

[0025] Rollers 15 are rotatably mounted at each of the four corners of the movable stage 9, and the four rollers are respectively installed inside the two first guide rails 5 and the two second guide rails 10. As an optional technical solution of this utility model, this makes it easier to position the four corners of the movable stage 9 between the first guide rails 5 and the second guide rails 10, and the rollers 15 are rolled inside the first guide rails 5 and the second guide rails 10, thereby limiting the installation position of the movable stage 9.

[0026] The following steps are required when using this type of hydraulic construction hoist:

[0027] 1) When in use, the transport platform 1 moves to one side of the pit, and at the same time, the hydraulic cylinder 4 shortens its movement, so that one end of the support frame 11 enters the interior of the pit.

[0028] 2) When the geared motor 12 is powered on, it drives the moving frame 9 and the geared motor 12 to rise to a certain height;

[0029] 3) Power on water pump 7 and run it to drain the foundation pit.

[0030] In summary, during operation, by setting up a transport platform 1 and a support frame 11, the support frame 11 is driven by a hydraulic cylinder 4 to rotate relative to the transport platform 1. This facilitates the control of one end of the support frame 11 to rotate into the pit. By setting up two first guide rails 5 and a second guide rail 10, it is easy to push the moving platform 9 and the water pump 7 along the length of the first guide rail 5. When the support frame 11 is in a horizontal state, the moving platform 9 is positioned at the end of the support frame 11 away from the transport platform 1. After the support frame 11 rotates into the pit, the water pump 7 enters the water, thereby avoiding... This design eliminates the need for manual entry into the pit, preventing potential hazards. Its simple overall structure effectively solves problems inherent in existing technologies. By incorporating two sprockets 14, a chain 6, and a reduction motor 12, with the output of the reduction motor 12 fixedly connected to one of the sprockets 14 and the chain 6 fixedly connected to one side of the moving platform 9, the reduction motor 12, when energized, causes the sprockets 14 to rotate. This, in turn, moves the moving platform 9 along the first guide rail 5 and the second guide rail 10, facilitating adjustment of the water pump 7's placement height within the pit and preventing the pump from sucking in mud and sand, thus ensuring smooth drainage.

[0031] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
