Description

Technical Field

[0001] This invention belongs to the field of hydraulic hoisting equipment, and in particular relates to a formwork hoisting device for hydraulic engineering construction. Background Technology

[0002] When lifting large objects on land, large cranes are usually used. However, when the operation is near or in a river, large cranes used on land are difficult to deploy and use. The slope of the riverbank, the high water content and looseness of the soil make it difficult to effectively fix the crane, which can easily lead to rollover accidents during lifting.

[0003] While existing technologies for large offshore floating cranes and platforms can achieve high stability when lifting large objects due to their large surface area and weight, inland waterways have complex variations in width and depth, making it difficult for large floating cranes to enter easily. Therefore, the lifting of large formwork equipment in inland waterways usually requires extensive planning, limiting early design standards, and using multi-equipment coordination, which restricts the structural design of the facilities. At the same time, the probability of risk increases exponentially when multiple equipment work together. Summary of the Invention

[0004] The purpose of this invention is to provide a formwork hoisting device for water conservancy engineering construction, which aims to solve the problems mentioned in the background art.

[0005] The present invention is implemented as follows: a formwork hoisting device for water conservancy engineering construction includes a floating crane platform and a hoisting component installed on the floating crane platform. The formwork hoisting device also includes an extension component and a counterweight hopper installed at the bottom of the floating crane platform. The extension component is installed at the position between the floating platform and the counterweight hopper. The extension component includes a horizontally arranged basic connecting frame and an extension connecting frame hinged at both ends of the basic connecting frame. The length of the extended connecting frame is less than that of the floating platform, and the maximum hinge limit angle between the extended connecting frame and the basic connecting frame is 180 degrees. When the extended connecting frame and the basic connecting frame are at a flat angle, the floating platform and the counterweight hopper slide along the length direction of the extended component, and the sliding directions are opposite.

[0006] As a further embodiment of the present invention: both the basic connecting frame and the extended connecting frame are provided with a set of guide connecting rails in parallel; When the basic connecting frame and the extended connecting frame are at a flat angle, the guide connecting rails of the adjacent connecting frames are connected end to end. Guide columns are provided at the bottom of the floating platform and at the top of the counterweight hopper, and the guide columns are slidably connected to the guide connecting rail.

[0007] As a further aspect of the present invention: the hoisting assembly includes: A boom base is fixedly installed on one end surface of the floating platform. The boom base is inclined in a direction outside the plane of the floating platform. The boom base is provided with locking bolt holes. The boom is hinged to the boom base. The hinged end of the boom is also provided with a telescopic limiter. When the boom rotates to be consistent with the tilt direction of the boom base, the telescopic limiter engages with the locking bolt hole.

[0008] As a further embodiment of the present invention: the hoisting assembly further includes a tie arm disposed on the surface of the floating platform at the end away from the boom base; The arm is tilted, and the tilting direction is opposite to that of the boom base; The surface of the floating platform is also equipped with a hoisting power unit in the inclined direction of the boom. The hoisting power unit is used to drive and wind up the hoisting rope. The hoisting rope is slidably engaged with the boom and the hoisting pulleys at the top end of the boom, and is suspended above the water surface on the inclined side of the boom.

[0009] As a further aspect of the present invention, it also includes a boom control assembly, specifically comprising: The boom lifting mechanism is provided at both sides of the boom, and the boom lifting drive winch and support pulley are provided at both sides of the boom base; The support pulley is positioned at a height higher than the highest point of the lifting arm actuator during rotation. The lifting arm actuator is connected to the lifting arm drive winch via a sling, and the sling slides in conjunction with the support pulley.

[0010] As a further aspect of the present invention: a hinged connector is fixedly provided on one side of the extended connecting frame, and the hinged connector is hinged to the basic connecting frame at a position extending beyond the end of the extended connecting frame; An extension telescopic component is hinged to the other side of the extension connecting frame. The end of the extension telescopic component is hinged to the basic connecting frame, and both ends of the extension telescopic component are inclined in the same vertical plane.

[0011] As a further embodiment of the present invention: the counterweight bottom compartment is configured with a hollow structure; The counterweight silo is connected to the outside via a water pumping device, and the water pumping device is a bidirectional pumping structure. When the water capacity of the counterweight silo changes, the total weight and draft of the counterweight silo and the floating platform change.

[0012] This invention provides a formwork hoisting device for water conservancy engineering construction. The floating crane adopts a multi-section split structure. Through the setting of foldable extension components and floating crane platform and counterweight bottom chamber that slide along the extension components, it achieves low space occupation and small planar space occupation in the non-operation state.

Detailed Implementation

[0015] To make the objectives, technical solutions, and advantages of this invention clearer, the invention will be further described in detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative and not intended to limit the invention.

[0016] The specific implementation of the present invention will be described in detail below with reference to specific embodiments.

[0017] like Figures 1 to 3 As shown, a formwork hoisting device for water conservancy engineering construction is provided in one embodiment of the present invention, including a floating platform 1 and a hoisting component 4 installed on the floating platform 1. The formwork hoisting device also includes an extension component 3 and a counterweight hopper 2 installed at the bottom of the floating platform 1. The extension component 3 is installed at the position between the floating platform 1 and the counterweight hopper 2. The extension component 3 includes a horizontally arranged basic connecting frame 310 and an extension connecting frame 320 hinged at both ends of the basic connecting frame 310. The length of the extended connecting frame 320 is less than that of the floating platform 1, and the maximum hinge limit angle between the extended connecting frame 320 and the basic connecting frame 310 is 180 degrees. When the extended connecting frame 320 and the basic connecting frame 310 are at a flat angle, the floating platform 1 and the counterweight hopper 2 slide along the length direction of the extended component 3, and the sliding directions are opposite.

[0018] In this embodiment of the invention, a formwork hoisting device for hydraulic engineering construction is provided. The floating crane adopts a multi-section split structure. Through the setting of foldable extension components 3 and floating platform 1 and counterweight bottom 2 that slide along the extension components, low space occupation and small planar space occupation are achieved in the non-operation state. This enables the floating crane to have better river passage and facilitates its travel in rivers of different sizes to reach the corresponding hydraulic hoisting sites. It effectively solves the problems of difficulty in setting up large land hoisting equipment in rivers and riverbanks and the inability of large water hoisting equipment to reach hoisting points through complex river terrain.

[0019] In one embodiment of the present invention, the application scenario is the hoisting and lifting of hydraulic equipment and formwork in inland waterways, mainly for the hoisting of large equipment and formwork. While large lifting vehicles can typically be used for hoisting large objects on land, large land-based lifting vehicles are difficult to deploy and use in scenarios involving the hoisting of hydraulic equipment near or within waterways. The slope of the riverbank, the high water content and looseness of the soil all make it difficult to effectively secure the lifting vehicles, easily leading to rollover accidents during hoisting. Hoisting equipment in waterways is even more challenging. Furthermore, large floating cranes and floating platforms at sea... The platform, with its large water surface area and weight, can achieve high stability when lifting large objects. However, in inland waterways have complex width and depth variations, making it difficult for large floating crane vessels to navigate. The technical solution of this embodiment is to optimize and upgrade the structure of the floating crane vessel, making it suitable for more complex inland waterways. Specifically, it mainly uses a foldable structure to allow the floating crane vessel to have two states: a small area for general operation and a large area for high stability during lifting operations. Here, the floating crane vessel is configured as a multi-layered structure with an extension component 3 connecting the floating platform 1 and the counterweight hopper 2. In reality, it serves as the connecting frame for the floating crane vessel, comprising a basic connecting frame 310 and additional extended connecting frames 320. When the floating crane vessel travels in the river, the extended connecting frames 320 on both sides fold upwards. At this time, the floating platform 1 and the counterweight hopper 2 are aligned on the same horizontal projection plane, i.e., at the upper and lower sides of the basic connecting frame 310. This significantly reduces the horizontal area occupied by the floating crane vessel (the specific reduction depends on the ratio between the basic connecting frame 310 and the extended connecting frame 320), greatly increasing the river's passability. When reaching the work site, the extended connecting frames 320 are lowered, positioning them at the same water level as the basic connecting frame 310. In the horizontal position, the length of the connecting frame of the floating crane increases, and the horizontal area increases. At this time, the floating platform 1 and the counterweight tank 2 move to both sides respectively (specifically, the direction of movement of the floating platform 1 and the counterweight tank 2 is determined, that is, the counterweight tank 2 should be away from the end of the object being lifted), forming a longer lever effect to obtain a larger force distribution plane. Here, it is also specifically limited that the length of a single extension connecting frame 320 should be less than that of the floating platform 1. The purpose is to use the structure of the floating platform 1 and the structure of the counterweight tank 2 to compensate for the structural strength at the hinge points between the two ends of the basic connecting frame 310 and the extension connecting frame 320 when expanding the area.

[0020] like Figure 2 and Figure 3 As shown, in a preferred embodiment of the present invention, both the basic connecting frame 310 and the extended connecting frame 320 are provided with a set of guide connecting rails 311 in parallel. When the basic connecting frame 310 and the extended connecting frame 320 are at a flat angle, the guide connecting rails 311 of the adjacent connecting frames are connected end to end. The bottom of the floating platform 1 and the top of the counterweight hopper 2 are each provided with a guide column, which is slidably connected to the guide connecting rail 311.

[0021] In one embodiment of the present invention, the spatial relationship between the basic connecting frame 310 and the extended connecting frame 320 and the positional relationship of the structure are further defined, and it is explained how the floating platform 1 and the counterweight hopper 2 slide with the basic connecting frame 310 and the extended connecting frame 320 (in the horizontal state). Here, a long track sliding cooperation method is used for connection and limitation.

[0022] like Figure 1 , Figures 4 to 6 As shown, in another preferred embodiment of the present invention, the hoisting assembly 4 includes: A boom base 420 is fixedly installed on one end surface of the floating platform 1. The boom base 420 is inclined toward the direction outside the plane of the floating platform 1. The boom base 420 is provided with locking bolt holes. The boom 410 is hinged to the boom base 420. The hinge end of the boom 410 is also provided with a telescopic limiter 450. When the boom 410 rotates to be consistent with the tilt direction of the boom base 420, the telescopic limiter 450 engages with the locking bolt hole.

[0023] Furthermore, the hoisting assembly 4 also includes a pull arm 430 disposed on the surface of the floating platform 1 at the end away from the boom base 420; The pull arm 430 is inclined, and the inclination direction is opposite to that of the boom base 420; The surface of the floating platform 1 is also provided with a hoisting power unit 440 in the inclined direction of the boom 430. The hoisting power unit 440 is used to drive and reel in the hoisting rope. The hoisting rope is slidably engaged with the hoisting pulleys provided at the top end of the boom 430 and the boom 410, and is suspended above the water surface on the inclined side of the boom 410.

[0024] In one embodiment of the present invention, the specific structure of the hoisting component 4 is supplemented. In inland waterways, there may be bridge height restrictions. Therefore, the boom 410 here is still foldable to save space in the vertical direction. The hoisting structure here is consistent with the traditional floating crane, which adopts the cooperative structure of boom 410 and pull arm 430. Both are inclined outward to obtain a more stable load-bearing effect. In use, the boom 410 is rotated. When it reaches the predetermined position, the telescopic limiters 450 extend at both ends and cooperate with the locking bolt holes to lock (the boom base 420 is also provided with a fixed physical limit structure to ensure safety). At this time, the sling that passes around the top pulley of boom 410 and the top pulley of pull arm 430 and is finally wound in the hoisting power unit 440 is released. The template to be hoisted is fixed by various fixing methods such as winding or fixing ring equipment, thus completing the hoisting preparation work.

[0025] like Figures 4 to 6 As shown, in a preferred embodiment of the present invention, it further includes a boom control assembly 5, specifically comprising: Lifting boom actuating members 530 are provided at both sides of the boom 410, and lifting boom driving winches 510 and support pulleys 520 are provided at both sides of the boom base 420; The support pulley 520 is positioned at a height higher than the highest point of the lifting arm actuator 530 during its rotation. The lifting arm actuator 530 is connected to the lifting arm drive winch 510 via a sling, and the sling slides in conjunction with the support pulley 520.

[0026] In one embodiment of the present invention, a lifting and lowering control structure for the boom 410 is added, which can be regarded as a fixed small pulley lifting structure. The sling cooperates with the boom 410 through the raised support pulley 520, so that when the boom drives the winch 510 to rotate, the lifting angle of the boom 410 is controlled by changing the release length of the sling.

[0027] like Figure 3 As shown, in another preferred embodiment of the present invention, a hinged connector 321 is fixedly provided on one side of the extension connector 320, and the hinged connector 321 is hinged to the basic connector 310 at a position extending beyond the end of the extension connector 320. An extension telescopic member 330 is hinged to the other side of the extension connecting frame 320. The end of the extension telescopic member 330 is hinged to the basic connecting frame 310, and both ends of the extension telescopic member 330 are inclined in the same vertical plane.

[0028] Furthermore, the counterweight bottom compartment 2 is designed with a hollow structure; The counterweight silo 2 is connected to the outside via a water pumping device, and the water pumping device is a bidirectional water pumping structure. When the water capacity of the counterweight silo 2 changes, the total weight and draft of the counterweight silo 2 and the floating platform 1 change.

[0029] In one embodiment of the present invention, the specific connection structure between the extension connecting frame 320 and the basic connecting frame 310 is described, and the lifting and releasing control of the extension connecting frame 320 is achieved by setting a diffusion telescopic member 330 with two ends staggered in the vertical direction; additionally, the hollow counterweight bottom chamber 2 has its internal water volume controlled by a water pumping device, which can increase the stability of the floating crane vessel when fully loaded during hoisting, and reduce the draft of the floating crane vessel when unloaded during movement. The lower draft enables the floating crane vessel to have better maneuverability and reduces the probability of running aground in shallow riverbeds. At the same time, in order to maintain stability when half-loaded, the space in the counterweight bottom chamber 2 is divided by several vertically set semi-partition baffles to prevent the liquid flow impact from causing platform instability during movement.

[0030] The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. Any modifications, equivalent substitutions, and improvements made within the spirit and principles of the present invention should be included within the protection scope of the present invention.
