Description

Technical Field

[0001] The present invention relates to the field of lifting technology, and in particular to a lifting device and method for power grid infrastructure construction. Background Art

[0002] Offshore platform-based observation stations are important infrastructure for implementing marine hydrological and meteorological observations, and can automatically obtain marine environmental observation data. These data include elements such as marine meteorology and marine hydrology. In addition, they can also monitor marine ecology. Offshore platform-based observation stations play an irreplaceable role in marine scientific research, disaster warning, environmental protection and resource management, and are an important part of the modern marine observation system. During the construction of offshore platform-based observation stations, power grid infrastructure construction is required, including the construction and transformation of power generation, transmission, substation, distribution and power facilities to meet the use of monitoring equipment and other power equipment of offshore platform-based observation stations, thereby ensuring the normal operation of offshore platform-based observation stations. During the construction of power grid infrastructure, lifting devices can be used to lift large equipment, materials and components, reducing the time and physical exertion of manual handling, thereby speeding up the construction progress.

[0003] Publication number CN118495369A discloses a lifting buffer device for power grid infrastructure construction, which solves the technical problem that the infrastructure facilities in the power grid infrastructure construction have no buffering function when being lifted, which easily causes damage to the facilities and affects the use of the facilities during the lifting process. It has the technical effect of being able to buffer the facilities during the lifting process, prevent damage, protect them intact, and facilitate installation.

[0004] Based on the existing technology, there are the following problems:

[0005] Although the above application documents can buffer the hoisted facilities and reduce the damage to the facilities during the hoisting process, the existing offshore platform-based observation station hoisting device is used for power grid infrastructure construction. Due to the strong winds and waves at sea, the stability of the hoisting device is affected, thereby affecting the lifting and landing position of the hoisting device and affecting the lifting efficiency. In addition, since the hoisting device is usually lifted by a cable, it is easily affected by the sea breeze and shakes, or even falls, which can easily damage the power grid infrastructure equipment. At the same time, there are certain safety hazards, which affect the construction of the power grid infrastructure and thus affect the construction of the offshore platform-based observation station. There are certain shortcomings. In order to solve the above problems, a hoisting device and method for power grid infrastructure construction are proposed. Summary of the invention

[0034] S1: placing the power grid infrastructure to be hoisted in the hanging basket, and then lifting the hanging basket to move the power grid infrastructure to the designated location;

[0035] S2: During the lifting process, when the hanging basket shakes greatly, the hanging basket is lifted to the highest position, and then the hanging basket is clamped and fixed by the cooperation of the first limiting mechanism and the second limiting mechanism, and the hanging basket is further fixed by the cooperation of the buckle mechanism and the auxiliary components to limit the violent shaking of the hanging basket.

[0036] The present invention provides a lifting device and method for power grid infrastructure construction. Compared with the prior art, it has the following beneficial effects:

[0037] 1. The present invention facilitates clamping and limiting the hanging basket after the hanging basket shakes violently through the cooperation of the first limiting mechanism and the second limiting mechanism to improve the stability of the hanging basket. After the hanging basket is limited by the first limiting mechanism and the second limiting mechanism, the buckle mechanism and the auxiliary mechanism cooperate to avoid lateral movement of the hanging basket after limiting, thereby further improving the stability. After the hanging basket is clamped and limited, the third limiting mechanism and the first lifting mechanism can still adjust the height of the hanging basket, so as to move the hanging basket and the power grid infrastructure in the hanging basket to the specified position, thereby facilitating the construction of an offshore platform-based observation station.

[0038] 2. The present invention cooperates with the first limiting mechanism and the second limiting mechanism. After the hanging basket shakes, the second lifting mechanism moves the hanging basket up to the highest position. At this time, the inner concave part of the limiting seat is located at the engaging position after the limiting arm rotates. Then, the limiting arm of the first limiting mechanism is driven by the driving mechanism to be embedded in the inner concave part of the limiting seat to clamp and fix the limiting seat, thereby limiting the hanging basket and reducing its shaking.

[0039] By making the first contact surface and the second contact surface contact the third contact surface and the fourth contact surface respectively, the stability of the engagement between the limit arm and the limit seat is improved, and the limit arm and the limit seat are prevented from being separated, so as to facilitate multiple limit uses;

[0040] By making the sides of the limiting seat away from each other to be concave, the distance between the concave part of the limiting seat and the two frames is greater than the width of the limiting arm, so that the limiting arm can smoothly enter the concave part of the limiting seat.

[0041] 3. The present invention cooperates with the snap mechanism and the auxiliary components to limit the lateral movement of the hanging basket after the first limiting mechanism and the second limiting mechanism cooperate to limit the hanging basket, thereby further improving the stability of the hanging basket, and conveniently monitoring the degree of squeezing of the shell by the hydraulic rod through the pressure sensor to avoid the situation where the position of the limiting arm entering the limiting seat is not at the center, that is, the blank space on both sides of the limiting arm is different, and the hydraulic rod can limit the limiting seat from both sides of the limiting arm.

[0042] 4. The present invention cooperates with the first lifting mechanism and the third limiting mechanism, so that after the first limiting mechanism and the second limiting mechanism limit the hanging basket, the hanging basket can be controlled to move down to a certain height, so as to place the hanging basket at a designated position for power grid infrastructure construction. When moving, the positioning rod and the positioning hole cooperate to avoid connecting the second connecting seat only through the cable of the first lifting mechanism, thereby improving the stability of the movement of the hanging basket.

[0064] 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. 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 creative work are within the scope of protection of the present invention.

[0065] Example 1: Please refer to Figure 1 , Figure 2 , Figure 4 , Figure 5 , Figure 6 , Figure 7 and Figure 8 A lifting device for power grid infrastructure construction includes a pulley mechanism 1 arranged outside a crane arm. The pulley mechanism 1 usually moves horizontally along the crane arm of the crane tower to adjust the horizontal position of the hanging basket 7.

It also includes a first connecting seat 2 arranged at the bottom of the pulley mechanism 1, a second connecting seat 5 arranged at the bottom of the first connecting seat 2, and a hanging basket 7 arranged at the bottom of the second connecting seat 5. The second connecting seat 5 is provided with a first limiting mechanism 6 for clamping the hanging basket 7 on both sides. A connecting assembly 9 is provided at the top of the hanging basket 7. The connecting assembly 9 is provided with a second limiting mechanism 8 cooperating with the first limiting mechanism 6 on both sides to limit the shaking of the hanging basket 7. The first limiting mechanism 6 includes:

[0066] The limiting arms 61 are rotatably arranged on both sides of the second connecting seat 5 and are arranged at intervals. A driving mechanism 11 for driving the limiting arms 61 to rotate is arranged on the top of the second connecting seat 5. The bottom of the limiting arm 61 is designed to be bent, and a first contact surface 62 and a second contact surface 63 are arranged at the bent portion of the bottom of the limiting arm 61. A buckle mechanism 64 is arranged on the side away from each other of the two limiting arms 61 on the same side of the second connecting seat 5.

[0067] The second limiting mechanism 8 comprises:

[0068] The limiting seat 81 is arranged on both sides of the connecting component 9. The sides of the limiting seat 81 that are away from each other are designed to be concave to form a third contact surface 84 and a fourth contact surface 83 that respectively abut against the first contact surface 62 and the second contact surface 63, so that the limiting arm 61 clamps and fixes the limiting seat 81, and the inner side of the limiting seat 81 is provided with an auxiliary mechanism 85 that cooperates with the snap mechanism 64.

[0069] In the specific implementation, when the hanging basket 7 shakes violently during the lifting process by the first lifting mechanism 4, the first winch of the first lifting mechanism 4 is completely reeled in to make the base plate 91 close to the second connecting seat 5, and then, the limiting arm 61 is driven to rotate by the driving mechanism 11 to make the bending part at the bottom of the limiting arm 61 embedded in the limiting seat 81, that is, the first contact surface 62 and the second contact surface 63 are respectively in contact with and pressed against the third contact surface 84 and the fourth contact surface 83, so that the limiting arm 61 clamps and fixes the limiting seat 81, thereby limiting the hanging basket 7, avoiding the hanging basket 7 being connected only by the cable of the second lifting mechanism 10, and improving the stability of the hanging basket 7.

[0070] By making the sides of the limiting seat 81 away from each other concave, the distance between the concave part of the limiting seat 81 and the two frames 82 is greater than the width of the limiting arm 61, so that the limiting arm 61 can smoothly enter the concave part of the limiting seat 81.

[0071] See also Figure 5 , the buckle mechanism 64 comprises:

[0072] The hydraulic rod 642 is fixed on the bottom side wall of the limit arm 61, and the side wall of the telescopic axis of the hydraulic rod 642 is fixedly sleeved with a limit piece, the side wall of the limit piece is fixedly provided with a guide rod 641 that penetrates the limit arm 61, and the side wall of the limit arm 61 is opened with a guide hole for sleeved with the guide rod 641, and the telescopic axis of the hydraulic rod 642 drives the guide rod 641 to move along the guide hole to limit the movement of the telescopic axis of the hydraulic rod 642.

[0073] See also Figure 1 , Fig. 9 , Fig.10 , Fig.11 and Fig.12 , the second limiting mechanism 8 also includes:

[0074] The frame 82 is fixedly arranged on both sides of the inner concave part of the limiting seat 81, so that a cavity 86 is formed between the frame 82 and the inner concave part of the limiting seat 81, and the auxiliary mechanism 85 is in the cavity 86. The auxiliary mechanism 85 includes:

[0075] The mounting seat 852 is fixedly arranged on the inner side of the limiting seat 81 and is located in the cavity 86. A pressure sensor 854 is fixedly arranged on the side of the mounting seat 852 close to the limiting arm 61. A shell 851 extending to the outside of the limiting seat 81 is sleeved on the side wall of the mounting seat 852. The shell 851 is sleeved on the outer side of the pressure sensor 854. A stop plate 856 is fixedly arranged on the side of the shell 851 close to the limiting arm 61.

[0076] The limiting ring 853 is fixed on the inner side of the limiting seat 81 , and the inner wall of the limiting ring 853 is sleeved on the outer wall of the shell 851 . The inner wall diameter of the limiting ring 853 is smaller than the side wall diameter of the abutment plate 856 to limit the movement of the shell 851 .

[0077] The auxiliary mechanism 85 also includes:

[0078] The first movable through grooves 857 are formed on the side wall of the mounting seat 852 and arranged in a circular array with the center point of the mounting seat 852, and the first movable through grooves 857 extend to the outside of the limiting seat 81;

[0079] The second movable groove 855 is opened on the side wall of the shell 851 and is arranged in a circular array with the center point of the shell 851. The second movable groove 855 and the first movable groove 857 are arranged alternately so that the side wall of the shell 851 is arranged in the first movable groove 857, so that the shell 851 moves along the first movable groove 857.

[0080] In a specific implementation, after the limit arm 61 is embedded in the concave part of the limit seat 81, the telescopic rod of the hydraulic rod 642 points to the frame 82, and then the hydraulic rod 642 is started to extend the telescopic shaft of the hydraulic rod 642, and the abutment plate 856 and the shell 851 are squeezed, so that the shell 851 squeezes the pressure sensor 854. When the pressure sensor 854 reaches the specified pressure information, the extension of the hydraulic rod 642 is stopped, so as to limit the limit seat 81, and prevent the limit seat 81 from moving laterally on the side wall of the limit arm 61, thereby preventing the hanging basket 7 from moving laterally, so as to improve the stability of the hanging basket 7;

[0081] The pressure sensor 854 is used to monitor the degree of compression of the housing 851 by the hydraulic rod 642, so as to prevent the limit arm 61 from entering the limit seat 81 at a position that is not at the center, that is, the empty spaces on both sides of the limit arm 61 are different. The hydraulic rod 642 can limit the limit seat 81 from both sides of the limit arm 61 to prevent the limit seat 81 from moving sideways.

[0082] By setting the limit ring 853 to limit the moving position of the housing 851, it is prevented that the hydraulic rod 642 causes excessive pressure on the housing 851 and the pressure sensor 854 when shaking violently, thereby avoiding damage to the pressure sensor 854, and facilitating the long-term use of the pressure sensor 854;

[0083] The first movable through slot 857 and the second movable through slot 855 facilitate the stable movement of the housing 851 along the first movable through slot 857 , which is convenient for practical use.

[0099] The limiting block 34 is fixedly disposed on the top of the positioning rod 32 , and the side wall diameter of the limiting block 34 is larger than the inner wall diameter of the positioning hole, so as to limit the positioning rod 32 from being separated from the positioning hole.

[0100] In the specific implementation, after the limiting arm 61 clamps and fixes the limiting seat 81, the hanging basket 7 is limited. In order to facilitate the lifting of the power grid infrastructure in the hanging basket 7 to the specified position, the second connecting seat 5 is driven to descend by the first lifting mechanism 4, so that the second connecting seat 5 and the hanging basket 7 are placed at the specified position. When the second connecting seat 5 descends, the second ear plate 31 and the positioning rod 32 are driven to move, so that the positioning rod 32 moves through the positioning hole at the top of the first ear plate 33, thereby limiting the descent of the second connecting seat 5 and the hanging basket 7, avoiding the second connecting seat 5 being connected only by the cable of the first lifting mechanism 4, and improving the stability of the movement of the hanging basket 7;

[0101] Through the cooperation of the first limiting mechanism 6 and the second limiting mechanism 8, when the hanging basket 7 shakes violently, the hanging basket 7 is raised to the highest position and the limiting seat 81 is clamped and fixed, so as to limit the hanging basket 7 and reduce the shaking degree of the hanging basket 7. After the hanging basket 7 is limited by the first lifting mechanism 4 and the third limiting mechanism 3, the hanging basket 7 can be controlled to move down to a certain height, and when moving, the stability of the movement of the hanging basket 7 is improved through the cooperation of the positioning rod 32 and the positioning hole, so as to facilitate the placement of the hanging basket 7 at the designated position for the convenience of power grid infrastructure construction;

[0102] By providing the first ear plate 33 and the second ear plate 31, it is convenient to position the positioning rod 32 on both sides of the boom, so as to prevent the movement of the positioning rod 32 from affecting the normal use of the boom, and to facilitate the installation of the positioning rod 32 of a specified length, so as to set the length of the positioning rod 32 according to actual conditions, so as to facilitate the first lifting mechanism 4 to stably move the hanging basket 7 downward by a specified distance;

[0103] The positioning rod 32 is limited by the limiting block 34 to prevent the positioning rod 32 from being separated from the positioning hole, thereby self-locking the lifting of the first lifting mechanism 4 to prevent falling.

[0104] The first lifting mechanism 4 comprises:

[0105] The first hoist is fixed at the bottom of the first connecting seat 2 , and a first hook is fixed at the bottom of the cable of the first hoist. The first hook is connected to the lifting ear at the top of the second connecting seat 5 to lift the second connecting seat 5 .

[0106] During specific implementation, the first hook at the bottom of the cable is connected to the lifting lug at the top of the second connecting seat 5, so as to facilitate the lifting of the second connecting seat 5 by the first winch.

[0107] A second lifting mechanism 10 for lifting the hanging basket 7 is provided at the bottom of the second connecting seat 5. The second lifting mechanism 10 includes:

[0108] The second hoist is fixedly arranged at the bottom of the second connecting seat 5 , and a second hook is fixedly arranged at the bottom of the cable of the second hoist. The second hook is connected to the lifting ear at the top of the base plate 91 to lift the hanging basket 7 .

[0109] In specific implementation, the second hook at the bottom of the cable is connected to the lifting lug at the top of the base plate 91, so that the base plate 91 and the hanging basket 7 can be lifted by the first hoist.

[0110] The electronic devices such as the first winch and pressure sensor 854 of the present invention are connected to the controller and the external power supply through wires for practical control and use. The hydraulic structures such as the hydraulic rod 642 of the present invention are connected to the external hydraulic system through oil circuits for practical control and use. The above are all prior arts and will not be elaborated here.

[0111] The embodiment of the present invention further provides a method for using a lifting device for power grid infrastructure construction, using a lifting device for power grid infrastructure construction, the method comprising the following steps:

[0112] S1: placing the power grid infrastructure to be hoisted in the hanging basket 7, and then hoisting the hanging basket 7 by the second hoisting mechanism 10 to move the power grid infrastructure to a designated location;

[0113] S2: During the hoisting process, when the hanging basket 7 shakes greatly due to the influence of sea breeze, the hanging basket 7 is hoisted to the highest position, that is, the position where the second hoist reels the cable to the maximum extent, and then the hanging basket 7 is clamped and fixed by the cooperation of the first limiting mechanism 6 and the second limiting mechanism 8, and the hanging basket 7 is further fixed by the cooperation of the buckle mechanism 64 and the auxiliary component to limit the violent shaking of the hanging basket 7;

[0114] In order to ensure stable lifting in the presence of sea breeze, the first lifting mechanism 4 cooperates with the third limiting mechanism 3 to allow the hanging basket 7 to stably descend a certain distance, thereby facilitating the lifting of power grid infrastructure and facilitating the construction of offshore platform-based observation stations.
