Description

Technical Field

[0001] The present invention relates to the technical field of isolating switches, and in particular to a hoisting and turning tool and an isolating switch. Background Art

[0002] With the rapid development of onshore photovoltaics in recent years, suitable sites for PV construction are becoming increasingly scarce. PV project construction in onshore areas faces certain limitations, while offshore areas offer vast expanses and excellent sunlight conditions, leading to increasing attention to the offshore photovoltaic industry. Currently, offshore photovoltaic construction follows the development model of onshore photovoltaics, employing a disassembled construction method. The construction of foundation PHC piles (prestressed high-strength concrete) is also largely done onshore, without precise positioning. Because they are primarily used in tidal flats and sea areas, PHC piles are relatively short, typically less than 15 meters. When hoisting PHC piles, ropes are typically tied at both ends. Once the pile is hoisted into position, a rope at the lower end is used to tilt the pile from a horizontal position to a vertical position.

[0003] However, when ropes are tied at both ends of the PHC pile, the friction between them is low during the pile turning process, which can easily cause the ropes to slip along the pile, affecting the construction process. Furthermore, every time a PHC pile is hoisted, workers must tie ropes at both ends, which is labor-intensive and reduces construction efficiency.

[0004] Therefore, how to reduce the labor intensity of construction workers and improve construction efficiency is a technical problem that those skilled in the art currently need to solve. Summary of the Invention

[0005] In view of this, an object of the present invention is to provide a lifting and turning tool to reduce the labor intensity of construction workers and improve construction efficiency.

[0006] In order to achieve the above object, the present invention provides the following technical solutions:

[0007] A lifting and turning tool, comprising

[0008] a first arm, wherein a first hanging member is provided on the first arm, and the first hanging member is located between two ends of the first arm;

[0009] a second arm, wherein a second hanging piece is provided on the second arm, and the second hanging piece is located between two ends of the second arm;

[0010] An intermediate jacking support, wherein the first end of the first holding arm is hingedly connected to the first end of the intermediate jacking support, the first end of the second holding arm is hingedly connected to the second end of the intermediate jacking support, and a clamping surface for clamping the outer side of the hoisted object is formed between the first holding arm, the second holding arm and the intermediate jacking support;

[0011] a first locking member, disposed at the second end of the first holding arm;

[0012] The second locking member is provided at the second end of the second arm, and the first locking member is used to lock with the second locking member.

[0013] Optionally, in the above-mentioned lifting and turning tool, the second locking member is a piston cylinder, and a locking hole is formed on the piston rod of the second locking member;

[0014] The first locking member includes a telescopic shaft. When the piston rod of the second locking member is extended, the locking hole can correspond to the telescopic shaft. The locking and unlocking of the first locking member and the second locking member are controlled by the telescopic action of the telescopic shaft.

[0015] Optionally, in the above-mentioned lifting and turning tool, the first locking member is a push rod motor.

[0016] Optionally, in the above-mentioned lifting and turning tool, a first fixing ear plate is provided at the second end of the first holding arm, and a fixing plate hole for the telescopic shaft to pass through is opened on the first fixing ear plate.

[0017] Optionally, in the above-mentioned lifting and turning tool, there are two first fixing ear plates arranged in parallel, and a fixing clamping groove for the piston rod of the second locking member to penetrate is formed between the two first fixing ear plates.

[0018] Optionally, in the above-mentioned lifting and turning tool, the second end of the second holding arm is provided with a second fixing ear plate for fixing the cylinder body of the second locking member.

[0019] Optionally, in the above-mentioned lifting and turning tool, a first limiting member is provided on the first holding arm, and a second limiting member is provided on the second holding arm. When the second end of the first holding arm and the second end of the second holding arm move away from each other to a preset distance, the first limiting member and the second limiting member offset each other, and the preset distance enables the hoisted object to enter the clamping surface.

[0020] Optionally, in the above-mentioned hoisting and turning tool, the first limiting member is an arc-shaped structure, with one end provided on the first holding arm and the other end provided with a first abutting base;

[0021] The second position-limiting member is an arc-shaped structure, and one end is provided on the second holding arm, and the other end is provided with a second abutting base for abutting against the first abutting base.

[0022] Optionally, in the above-mentioned lifting and turning tool, a rubber buffer pad is provided on the clamping surface.

[0023] Optionally, in the above-mentioned lifting and turning tool, the lifting rope assembly cooperating with the first lifting member and the second lifting member includes:

[0024] There are two first hanging ropes, wherein the first end of one of the first hanging ropes is connected to the first hanging member, and the first end of the other first hanging rope is connected to the second hanging member;

[0025] a hanging beam, to which the second ends of the two first hanging ropes are connected;

[0026] The second lifting rope is connected to the lifting beam and is used for lifting the lifting device.

[0027] Optionally, in the above-mentioned hoisting and turning tool, the hoisted part is a PHC pipe pile, and the clamping surface is an arc surface that cooperates with the PHC pipe pile.

[0028] Optionally, in the above-mentioned lifting and turning tool, when the first locking member and the second locking member are locked, a tensioning avoidance gap is provided between the second end of the first holding arm and the second end of the second holding arm.

[0029] The hoisting and turning tool provided by the present invention is an embracing structure with a contact area larger than that of the rope. The hoisting and turning tool has two states: an open state and a closed state. When it is necessary to hoist the hoisted part, the hoisting rope pulls the first hoisting part and the second hoisting part, and the hoisting and turning tool is lowered above the hoisted part so that the middle top support is placed on the hoisted part. Under the support of the hoisted part, as the hoisting rope continues to be lowered, the hoisting rope loses its tension, and the first arm and the second arm rotate under the action of gravity. The second end of the first arm and the second end of the second arm approach each other, so that the embracing surface fits on the hoisted part. Then, the first and second locking parts are used to lock the first and second arms, so that the first and second arms are in a closed state and hold the hoisted part tightly. The friction between the first and second arms and the hoisted part can meet the requirements of the hoisting part during the turning process.

[0030] After the hoisting and turning operations are completed, it is only necessary to unlock the first locking member and the second locking member, and the second end of the first arm and the second end of the second arm are in a free state. When the hoisting rope is lifted, the hoisting rope pulls the first hoisting member and the second hoisting member, driving the first arm and the second arm to rotate to an open state, and the hoisted member is separated from the first arm and the second arm through the opening between the second end of the first arm and the second end of the second arm. The present invention can also achieve the holding and separation of the hoisting and turning tool and the hoisted member through the lowering and lifting actions of the hoisting rope. Compared with the tying rope in the prior art, it has a larger contact area, which can avoid slipping during the hoisting and turning process and affecting the construction. At the same time, it reduces the labor intensity of the construction workers and improves the construction efficiency. BRIEF DESCRIPTION OF THE DRAWINGS

[0043] The core of the present invention is to provide a hoisting turning tool to reduce the labor intensity of construction workers and improve construction efficiency.

[0044] The following will clearly and completely describe the technical solutions in the embodiments of the present invention in conjunction with the accompanying drawings. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0045] like Figure 1-Figure 3 As shown, an embodiment of the present invention discloses a lifting and turning tool including a first holding arm 101 , a second holding arm 104 , an intermediate jacking 107 , a first locking member 117 and a second locking member 115 .

[0046] The first arm 101 is provided with a first hanging member 108, located between its two ends and connected to the hanging rope. The surface of the first arm 101 that contacts the suspended object 200 should conform to the outer surface of the suspended object 200 to achieve a larger contact area. For example, if the suspended object 200 is a PHC pile, the surface of the first arm 101 that contacts the suspended object 200 should be a circular arc surface that matches the PHC pile.

[0047] The second arm 104 is provided with a second hanging member 109, located between its two ends and connected to the hanging rope. The surface of the second arm 104 that contacts the suspended object 200 should conform to the outer surface of the suspended object 200 to achieve a larger contact area. For example, if the suspended object 200 is a PHC pile, the surface of the second arm 104 that contacts the suspended object 200 should be a circular arc surface that matches the PHC pile.

[0048] It should be noted that, since the PHC pile is a cylindrical tube, the first arm 101 and the second arm 104 can have the same structure and be arranged relative to each other, which helps to reduce the manufacturing cost and maintenance cost of the accessories.

[0049] The first end of the first cradle 101 is hinged to the first end of the intermediate jacking support 107 via a first hinge axis 103, and the first end of the second cradle 104 is hinged to the second end of the intermediate jacking support 107 via a second hinge axis 106. A clamping surface for clamping the outside of the suspended object 200 is formed between the first cradle 101, the second cradle 104, and the intermediate jacking support 107. The suspended object 200 is a PHC pile, and the clamping surface is a circular arc surface that mates with the PHC pile. In this embodiment, the addition of the intermediate jacking support 107 allows the first cradle 101 and the second cradle 104 to be arranged on either side of the intermediate jacking support 107. Furthermore, during the lifting process, the intermediate jacking support 107 does not deflect and remains horizontal, ensuring that it first contacts the suspended object 200. This is a prerequisite for the first cradle 101 and the second cradle 104 to automatically close.

[0050] The first locking member 117 is arranged at the second end of the first arm 101, and the second locking member 115 is arranged at the second end of the second arm 104. The first locking member 117 is used to lock with the second locking member 115, so that the hoisted member 200 will not detach from the opening between the second end of the first arm 101 and the second end of the second arm 104.

[0051] The hoisting turning tool provided by the present invention is a loop structure with a contact area larger than that of the rope. The hoisting turning tool has two states, one of which is an open state ( Figure 4 The one shown is the open state), one is the closed state ( Figure 2 When the hoisted part 200 needs to be hoisted, the hoisting rope pulls the first hoisting part 108 and the second hoisting part 109, and the hoisting turning tool is lowered above the hoisted part 200, so that the middle jacking support 107 is placed on the hoisted part 200 (as shown in FIG. Figure 4 As shown, supported by the suspended object 200, the ropes continue to descend, losing tension. Under the action of gravity, the first arm 101 and the second arm 104 rotate, and the second ends of the first arm 101 and the second arm 104 approach each other, so that the clasping surfaces contact the suspended object 200. The first and second locking members then lock the first and second arms 101 and 104, closing them and securing the suspended object 200. The friction between the first and second arms 101, 104, and the suspended object 200 is sufficient to ensure that the suspended object 200 can be turned over.

[0052] After the lifting and turning operations are completed, it is only necessary to unlock the first locking member 117 and the second locking member 115. The second end of the first arm 101 and the second end of the second arm 104 are in a free state. When the lifting rope is lifted, the lifting rope pulls the first hanging member 108 and the second hanging member 109, driving the first arm 101 and the second arm 104 to rotate to the open state, and the hoisted member 200 is detached from the first arm 101 and the second arm 104 through the opening between the second end of the first arm 101 and the second end of the second arm 104. The present invention can also realize the embrace and separation of the lifting and turning tool and the hoisted part 200 through the lowering and lifting actions of the lifting rope. Compared with the binding rope in the prior art, it has a larger contact area, which can avoid slipping during the lifting and turning process and affecting the construction. At the same time, since the lifting and turning tool can automatically close after being lowered to surround the hoisted part 200, and can automatically open by lifting after being unlocked to separate from the hoisted part 200, the labor intensity of the construction workers is reduced and the construction efficiency is improved.

[0053] In a specific embodiment of the present invention, the second locking member 115 is a piston cylinder, and the piston rod has a cylinder body and a piston rod. The cylinder body of the piston cylinder is fixed to the second end of the second arm 104, and the piston rod can be controlled to extend and retract. A locking hole is provided on the piston rod of the second locking member 115.

[0054] The first locking member 117 includes a telescopic shaft 1171. When the piston rod of the second locking member 115 is extended, the locking hole and the telescopic shaft 1171 align. The telescopic shaft's extension and retraction control the locking and unlocking of the first locking member 117 and the second locking member 115. The first locking member 117 can be a push rod motor, and the telescopic shaft 1171 is the push rod of the push rod motor.

[0055] When it is necessary to lift the hoisted object 200, the lifting rope pulls the first lifting member 108 and the second lifting member 109, so that the first holding arm 101 and the second holding arm 104 are in the open state, and the lifting turning tool is lowered above the hoisted object 200. As the lifting rope continues to be lowered, the lifting rope loses tension, and the first holding arm 101 and the second holding arm 104 rotate under the action of gravity. The second end of the first holding arm 101 and the second end of the second holding arm 104 approach each other, and then the piston rod of the second locking member 115 is extended to the locking hole of the piston rod and corresponds to the telescopic shaft 1171. The telescopic shaft 1171 of the first locking member 117 is controlled to extend and insert into the locking hole of the piston rod, so that the first locking member 117 is connected to the second locking member 115. Then the piston rod of the second locking member 115 is controlled to retract, which will cause the first holding arm 101 and the second holding arm 104 to hold the hoisted object 200 tightly.

[0056] After the lifting and turning operations are completed, first control the piston rod of the second locking member 115 to extend slightly to remove the clamping force of the first arm 101 and the second arm 104, then control the telescopic shaft 1171 of the first locking member 117 to withdraw from the locking hole of the piston rod, and then control the piston rod of the second locking member 115 to retract, so that the second end of the first arm 101 and the second end of the second arm 104 are in a free state. When the lifting rope is lifted, the lifting rope pulls the first lifting member 108 and the second lifting member 109, driving the first arm 101 and the second arm 104 to rotate to the open state, and the hoisted member 200 is separated from the first arm 101 and the second arm 104.

[0057] The hoisting and turning tool disclosed in the embodiment of the present invention can realize the horizontal hoisting and turning of PHC pipe piles, and almost no human assistance is required during the hoisting process. After the hoisting is in place, the buckle can be automatically removed, which can greatly reduce human operation and further improve construction efficiency. At the same time, the large-area encircling structure is adopted to ensure the contact area with the PHC pipe pile, which can protect the pile body of the PHC pipe pile to the greatest extent and improve the safety of the hoisting operation.

[0058] When the piston rod of the second locking member 115 retracts, it pulls the telescopic shaft 1171 of the first locking member 117. To prevent the piston rod from pulling the telescopic shaft 1171 over a large distance and damaging the first locking member 117, a first fixing lug 116 is provided at the second end of the first embracing arm 101 in this embodiment. The first fixing lug 116 has a fixing plate hole for the telescopic shaft 1171 to pass through.

[0059] When the first locking member 117 and the second locking member 115 need to be locked, the piston rod of the second locking member 115 is controlled to extend until the locking hole of the piston rod corresponds to the telescopic shaft 1171. Then, the telescopic shaft 1171 of the first locking member 117 is controlled to extend. The telescopic shaft 1171 is respectively inserted into the fixing plate hole and the locking hole of the piston rod, so that the first locking member 117 and the second locking member 115 are connected. Then, the piston rod of the second locking member 115 is controlled to retract. The piston rod pulls the telescopic shaft 1171. The telescopic shaft 1171 transmits force to the first cradle arm 101 through the first fixing lug plate 116, so that the first cradle arm 101 and the second cradle arm 104 can clamp the hoisted object 200. The first fixing lug plate 116 can limit the telescopic shaft 1171, preventing it from deflecting when subjected to force, thereby avoiding damage to the telescopic shaft 1171 due to tension.

[0060] Furthermore, two first fixing lugs 116 are arranged in parallel, and a fixing groove is formed between the two first fixing lugs 116 for the piston rod of the second locking member 115 to pass through. In this embodiment, by providing two first fixing lugs 116, after the piston rod of the second locking member 115 is extended, it can just extend between the two first fixing lugs 116. When the piston rod retracts, the telescopic shaft 1171 is supported on the two first fixing lugs 116, further protecting the first locking member 117.

[0061] The width of the retaining groove formed between the two first retaining lugs 116 is greater than the diameter of the piston rod of the second locking member 115, thereby facilitating insertion of the piston rod of the second locking member 115 into the retaining groove. Those skilled in the art will appreciate that the end of the retaining groove facing the second locking member 115 may be provided with a larger guide opening to further facilitate insertion of the piston rod of the second locking member 115. In other words, the end of the retaining groove facing the second locking member 115 may have a gradually flaring structure, with the opening gradually widening toward the second locking member 115.

[0062] In one embodiment of the present invention, a second fixing lug 114 is provided at the second end of the second arm 104 for securing the cylinder of the second locking member 115. The method for securing the second locking member 115 is not limited in this application, as long as the second locking member 115 can be mounted on the second arm 104 without affecting the extension and retraction of the piston rod.

[0063] When the lifting rope pulls the first lifting member 108 and the second lifting member 109, it will pull the first arm 101 to rotate along the first hinge axis 103, and pull the second arm 104 to rotate along the second hinge axis 106 until the first arm 101 and the second arm 104 interfere with each other, making the opening between the first arm 101 and the second arm 104 (that is, the distance between the second end of the first arm 101 and the second end of the second arm 104) too large.

[0064] To prevent the openings of the first and second embracing arms 101, 104 from being too large, in one embodiment of the present invention, a first stopper 102 is provided on the first embracing arm 101, and a second stopper 105 is provided on the second embracing arm 104. When the second ends of the first and second embracing arms 101, 104 move away from each other to a predetermined distance, the first and second stoppers 102, 105 collide. The predetermined distance allows the hoisted object 200 to enter the clamping surface. In this embodiment, the first and second stoppers 102, 105 restrict the openings of the first and second embracing arms 101, 104, allowing the hoisted object 200 to enter through the openings without causing the openings to become too large, which could affect construction efficiency.

[0065] Furthermore, the first stopper 102 is an arc-shaped structure, with one end disposed on the first arm 101 and the other end provided with a first abutting base. The second stopper 105 is an arc-shaped structure, with one end disposed on the second arm 104 and the other end provided with a second abutting base for contacting with the first abutting base. The first stopper 102 and the second stopper 105 can have the same structure and be arranged relative to each other, so that when the first arm 101 and the second arm 104 rotate relative to each other, the first stopper 102 and the second stopper 105 also rotate relative to each other. Designing the first stopper 102 and the second stopper 105 as an arc-shaped structure ensures that the first abutting base and the second abutting base are in surface contact when they rotate to abut each other, thereby ensuring stable limiting.

[0066] To prevent the hard structures of the first and second arms 101, 104 from colliding with the suspended object 200 when clamping it, potentially damaging it, a specific embodiment of the present invention provides rubber cushions 112 on the clamping surfaces. Specifically, rubber cushions 112 are installed on the surfaces of the first and second arms 101, 104, and intermediate supports 107 that contact the suspended object 200. This ensures that the local pressure at the lifting location meets the compressive strength requirements of the suspended object 200, preventing damage to the suspended object 200.

[0067] In a specific embodiment of the present invention, the suspension rope assembly cooperating with the first suspension member 108 and the second suspension member 109 includes a first suspension rope 113 , a second suspension rope 111 and a suspension beam 110 .

[0068] There are two first lifting ropes 113, one of which has its first end connected to the first hanging member 108, and the other has its first end connected to the second hanging member 109. The second ends of both first lifting ropes 113 are connected to the lifting beam 110, so that after the first locking member 117 and the second locking member 115 are locked, the two first lifting ropes 113 remain parallel and do not converge. The second lifting rope 111 is connected to the lifting beam 110 for use in lifting the lifting device.

[0069] Furthermore, when the first locking member 117 and the second locking member 115 are locked, there should be a tensioning avoidance gap between the second end of the first arm 101 and the second end of the second arm 104 to provide space for the piston rod of the second locking member 115 to retract.

[0070] like Figure 5 As shown, when hoisting the hoisted member 200, it is necessary to fix two lifting points of the hoisted member 200, one of which can use the hoisting turning tool 100 disclosed in this embodiment, and the other can use the tying rope 300. Of course, both lifting points of the hoisted member 200 can also be equipped with the hoisting turning tool 100.

[0071] like Figure 6 As shown, after the hoisted part 200 is hoisted to the target position, the tying rope 300 can be controlled to be lowered, and the hoisting and turning tool 100 can remain stationary. Even if the tying rope 300 slides relative to the hoisted part 200 due to low friction, the turning action will not be affected under the action of the hoisting and turning tool 100.

[0072] like Figure 7 As shown, when the suspended member 200 is in a vertical position, the hoisting turning tool 100 lowers the suspended member 200 to the target position and construction can be carried out. After the suspended member 200 is in a vertical position, the first hanging member 108 and the second hanging member 109 are located on the axis of the suspended member 200, so that when the suspended member 200 is in a vertical position, the first hanging member 108 and the second hanging member 109 are located on the vertical plane where the center of gravity of the suspended member 200 is located, thereby preventing the suspended member 200 from tilting.

[0073] It should be noted that the various embodiments in this specification are described in a progressive manner, and each embodiment focuses on the differences from other embodiments. The same and similar parts between the various embodiments can be referenced to each other.
