Description

Technical Field

[0001] The invention relates to the technical field of power iron towers, in particular to a hoisting device for installing a power iron tower. Background Art

[0002] Power towers, also known as transmission towers or high-voltage towers, are structures used to support high-voltage transmission lines. They play a vital role in the power system, ensuring the transmission of electricity from power stations to power-consuming areas. They are divided into many types according to different usage scenarios and usage requirements, such as self-supporting towers, guyed towers and single-tube towers. Among them, single-tube towers are widely used in urban distribution networks and landscape-sensitive areas due to their beauty, space saving, easy installation and maintenance.

[0003] A single-tube tower is usually formed by splicing multiple tower sections and is installed after being transported to the installation site. Currently, when installing a single-tube tower, the required base is first cast at the designated installation location, and then the lowest tower section is hoisted to the top of the designated location through external lifting equipment. The tower section is manually guided to dock with the base and fixed and locked. After that, the external lifting equipment hoists each tower section from bottom to top in turn. During the connection of two adjacent tower sections, the stairs on the tower section are manually climbed to the fixed tower section on the lower side to guide the two tower sections to dock. After docking, the two tower sections are manually fixed and locked, and the installation process of the single-tube tower is finally completed.

[0004] The above-mentioned installation process has the following problems: during the docking installation of two adjacent tower sections, after the upper tower section is lifted by external lifting equipment to the top of the fixed lower tower section, the two tower sections are mainly guided to dock by the staff located on the stairs of the lower tower section. The manual guidance accuracy is low. Secondly, the stairs on the tower section can only accommodate one staff member to climb up or stand, so the overall lifting efficiency is low, and the overall height of the single-tube tower is relatively high, so personnel are required to climb continuously for guidance and installation.

[0030] In order to make the above-mentioned objects, features and advantages of the present invention more obvious and easy to understand, the specific embodiments of the present invention are described in detail below in conjunction with the accompanying drawings. In the following description, many specific details are set forth to facilitate a full understanding of the present invention. However, the present invention can be implemented in many other ways different from those described herein, and those skilled in the art can make similar improvements without violating the connotation of the present invention, so the present invention is not limited by the specific embodiments disclosed below.

[0031] like Figure 1 and Figure 2As shown, a hoisting device for installing an electric tower comprises: two upper and lower moving frames 1, the two moving frames 1 are respectively arranged on two upper and lower adjacent tower sections, the moving frame 1 is a ring with an opening on the rear side, and a climbing unit 2 for climbing along the length direction of the tower section is arranged on the moving frame 1, the climbing unit 2 comprises a horizontal column 20, two groups of column groups symmetrically distributed on the left and right are slidably penetrated on the moving frame 1, the column group comprises a plurality of horizontal columns 20 distributed in the circumferential direction and with horizontal axes and pointing to the axes of the moving frame 1, the end faces of the horizontal columns 20 located on the inner side of the moving frame 1 are fixedly provided with U-shaped blocks 21 with openings facing the tower section, a climbing wheel 22 is arranged in the U-shaped block 21 through rotation of a rotating column, the rotating column is connected to an external motor, and the climbing unit 2 also comprises a locking group 23 for locking the climbing wheel 22.

[0032] like Figure 1 and Figure 2 As shown, a guiding mechanism 3 is commonly provided on the upper and lower moving frames 1, and the guiding mechanism 3 includes a plate frame 30. Four plate frames 30 distributed in a matrix are fixedly provided on the opposite back surfaces of the two moving frames 1, and guiding columns 300 with vertical axes are fixedly provided on the upper and lower end surfaces of the upper plate frame 30, and guiding cylinders 301 with vertical axes are fixedly provided on the upper and lower end surfaces of the lower plate frame 30, and the openings of the guiding cylinders 301 are chamfered.

[0033] like Figure 1 As shown, the guiding mechanism 3 also includes an auxiliary unit 4. The two mobile frames 1 are commonly provided with an auxiliary unit 4 for assisting the guiding process. The auxiliary unit 4 includes a clamping plate 40. The mobile frame 1 is provided with two groups of left-right symmetrical plate groups. The plate group includes two upper and lower distributed and arc-shaped clamping plates 40, and the inner arc surface of the clamping plate 40 faces the tower section.

[0034] When the upper tower section is hoisted to dock with the lower tower section, the guide column 300 is inserted into the corresponding guide tube 301 to limit and guide the docking process of the two.

[0035] During the installation of a power tower, the lowest tower section is first hoisted and moved to the installation base by external lifting equipment such as a crane, and the installation process of the tower section is manually guided. After the tower section is fixed on the installation base, the remaining tower sections are hoisted. That is, after the lowest tower section is in a fixed state, the remaining tower sections are hoisted.

[0036] During operation, the staff places the lower mobile frame 1 on the lower tower section. The opening area of ​​the mobile frame 1 is convenient for the staff to place the mobile frame 1 on the tower section, and the opening area of ​​the mobile frame 1 faces the stairs on the tower section. The external hoisting equipment works to lift the upper tower section and repeats the above operation, placing the upper mobile frame 1 on the upper tower section, and all the climbing wheels 22 on the same mobile frame 1 are locked through the locking group 23, and kept in close contact with the tower section, which is convenient for subsequent climbing operations. At the same time, through the above operation, the axis of the mobile frame 1 is made to be in line with the axis of the tower section, and the external motor works to rotate the climbing wheel 22, so that The mobile frame 1 moves synchronously, the mobile frame 1 of the upper tower section moves to its lower end, and the mobile frame 1 of the lower tower section moves to its upper end. Then, the external lifting equipment works to drive the upper tower section to move to the top of the lower tower section and then gradually moves downward. During the downward movement, the clamping plate 40 on the mobile frame 1 presses the tower section so that the axis of the tower section is colinear with the axis of the mobile frame 1. At the same time, the guide column 300 is gradually inserted into the guide cylinder 301, so that the upper and lower mobile frames 1 are opposite to each other, which indirectly aligns the two tower sections up and down, thereby realizing guided docking. After docking, the staff fixes the upper tower section by tightening the bolts.

[0037] Afterwards, the mobile frame 1 on the lower tower section is moved downward by the climbing unit 2 thereon, removed manually and installed again on the tower section to be hoisted, and the mobile frame 1 on the upper tower section is moved upward to the upper area of ​​the tower section by the climbing unit 2 thereon, and the above operations are repeated to complete the hoisting and guiding process of the subsequent tower sections.

[0038] like Figure 1 , Figure 2 , Figure 4 and Figure 5 As shown, the locking group 23 includes a spring 230, and a spring 230 mounted on the corresponding horizontal column 20 is fixedly arranged between the U-shaped block 21 and the corresponding moving frame 1. The outer arc surface of the moving frame 1 is symmetrically slidably arranged with an arc strip 231, and the end surface of the arc strip 231 facing the adjacent horizontal column 20 is fixedly provided with an L-shaped positioning block 232 corresponding to the horizontal column 20. The horizontal section of the positioning block 232 is chamfered near the end surface of the horizontal column 20, and a slot 233 is opened on the horizontal column 20. The direction of the slot 233 from the U-shaped block 21 to the arc strip 231 is a triangular section and a rectangular section, and the inclined surface of the triangular section of the slot 233 faces the corresponding positioning block 232.

[0039] During operation, in the process of moving the mobile frame 1 to surround the corresponding tower section, the tower section squeezes the climbing wheel 22 on the mobile frame 1, so that the climbing wheel 22 drives the U-shaped block 21 and the horizontal column 20 to move in the direction away from the axis of the mobile frame 1, and the spring 1 230 is compressed. At the same time, the elastic force generated by the compression deformation of the spring 1 230 makes the corresponding climbing wheel 22 close to the outer wall of the tower section. All the climbing wheels 22 on the same mobile frame 1 are close to the outer wall of the tower section at the same time, so that the axis of the mobile frame 1 is initially collinear with the axis of the tower section. Then, the arc bar 231 is manually rotated, and the arc bar 231 drives the positioning block 232 thereon to move synchronously, and the positioning The block 232 is gradually inserted into the slot 233. The blocking block 232 first contacts the inclined surface of the triangular section of the slot 233 and gradually squeezes the inner wall of the slot 233, so that the horizontal column 20 drives the corresponding climbing wheel 22 to press against the outer wall of the tower section. Then the blocking block 232 moves into the rectangular section of the corresponding slot 233, completing the fixed locking of the horizontal column 20 and the climbing wheel 22, and then locking the moving frame 1 in the circumferential direction, which is convenient for the subsequent guiding process and the climbing process of the moving frame 1 in the axial direction of the tower section. The chamfered area of ​​the blocking block 232 makes it easy for the blocking block 232 to be inserted into the slot 233 and contact and cooperate with the inclined surface of the triangular section of the slot 233.

[0040] like Figure 1 , Figure 2 and Figure 3 As shown, the auxiliary unit 4 also includes a hinge bar 41, and the upper and lower end surfaces of the mobile frame 1 are hingedly provided with two left-right symmetrical hinge bars 41 hinged to the corresponding clamping plates 40. The mobile frame 1 is rotatably penetrated by a threaded rod 410 with two horizontal axes and pointing to the axis of the mobile frame 1. The threaded rod 410 is located between the two corresponding upper and lower hinge bars 41, and a rectangular block 411 is threadedly sleeved on the threaded rod 410. A driving bar 412 is hingedly installed between the rectangular block 411 and the corresponding hinge bar 41.

[0041] like Figure 1 and Figure 3 As shown, the auxiliary unit 4 also includes a gear 413, and the end face of the threaded rod 410 away from the rectangular block 411 is fixedly provided with a gear 413, and the outer arc surface of the mobile frame 1 is slidably provided with two left-right symmetrical and arc-shaped tooth plates 414 through the connecting block, and the tooth plates 414 are meshed with adjacent gears 413.

[0042] like Figure 1 , Figure 3 and Figure 6As shown, the auxiliary unit 4 also includes a vortex spring 415, and a vortex spring 415 located between the corresponding gear 413 and the mobile frame 1 is commonly provided between the mobile frame 1 and the threaded rod 410, and two left-right symmetrical support rope members 416 are fixedly provided on the opposite back surfaces of the two mobile frames 1 through a connecting block, and a rope 417 is commonly fixedly provided between the two tooth plates 414 on the same mobile frame 1, and the rope 417 passes through the two support rope members 416 on the same mobile frame 1, and arc-shaped push rope plates 418 are fixedly provided on the upper and lower end surfaces of the mobile frame 1 through a connecting frame, and the two push rope plates 418 on the same mobile frame 1 are symmetrical up and down and the inner arc surfaces are opposite to each other, and the connecting frames on the two mobile frames 1 are staggered left and right.

[0043] like Figure 6 and Figure 7 As shown, the front end surface of the connecting frame on the upper movable frame 1 is fixedly provided with a guide block 42 through a fixing block 1, and the front end surface of the connecting frame on the lower movable frame 1 is fixedly provided with a guide plate 420 through a fixing block 2. A guide groove 421 is opened on the guide plate 420, and the guide groove 421 passes through the upper and lower end surfaces of the corresponding guide plate 420. The guide groove 421 is, from left to right, an isosceles trapezoid with a small diameter section facing right and a rectangular section cooperating with the guide plate 420, and the upper and lower ends of the guide groove 421 are chamfered.

[0044] During operation, after the mobile frame 1 is locked on the corresponding tower section and moved to the specified position of the tower section, the external lifting equipment lifts the upper tower section to the top of the lower tower section and gradually moves it downward. During the downward movement, the position of the upper tower section is adjusted, and the guide block 42 is made to be opposite to the guide groove 421 up and down. As the upper tower section gradually moves downward, the guide block 42 is inserted into the guide groove 421 to complete the initial guidance, which is convenient for the lifting of the upper tower section and at the same time makes the push rope plate 418 on the connecting frame opposite to the relative rope 417 up and down. Secondly, the isosceles trapezoidal section on the guide groove 421 and the upper and lower chamfers of the guide groove 421 make it convenient for the guide block 42 to move into the guide groove 421 and cooperate with the rectangular section of the guide groove 421 to perform the guiding operation.

[0045] As the upper tower section gradually moves downward, the rope-pushing plate 418 on the mobile frame 1 approaches the rope 417 on the other mobile frame 1, and finally the rope-pushing plate 418 pushes the rope 417 on the other mobile frame 1. The rope 417 pulls the tooth plates 414 at both ends thereof and makes the corresponding two tooth plates 414 approach each other. During the movement of the tooth plates 414, the tooth plates 414 mesh with the corresponding gears 413, so that the gears 413 drive the threaded rod 410 to rotate. Through the threaded cooperation between the threaded rod 410 and the corresponding rectangular block 411, The rectangular block 411 is close to the tower section, and the rectangular block 411 drives the driving bar 412 thereon to move synchronously. The transmission of the driving bar 412 enables the hinged bar 41 to drive the clamping plate 40 thereon to move synchronously until the two clamping plates 40 corresponding to the same rectangular block 411 both clamp the corresponding tower section. The inner arc surfaces of the four clamping plates 40 on the mobile frame 1 simultaneously clamp the tower section, so that the axis of the mobile frame 1 is collinear with the axis of the corresponding tower section, completing the second limiting process of the tower section, and at the same time improving the stability of the mobile frame 1 during the docking process.

[0046] During the rotation of the above-mentioned gear 413, the vortex spring 415 is deformed. After the lifting process is completed, the rope pushing plate 418 stops pushing the corresponding rope 417. The elastic force generated by the deformation of the vortex spring 415 causes the gear 413 and the threaded rod 410 to reverse, so that the rectangular block 411 is reset and the tooth plate 414 is reset to the initial state, which is convenient for subsequent operations.

[0047] like Figure 1 and Figure 6 As shown, the guiding mechanism 3 also includes a docking column 31, and the end surface of the clamping plate 40 on the upper side of the mobile frame 1 away from the mobile frame 1 is fixedly provided with a docking column 31, and the clamping plate 40 on the lower side of the mobile frame 1 is provided with a docking groove 310 that cooperates with the docking column 31.

[0048] When the clamping plate 40 clamps the tower section and completes the locking of the moving frame 1, the axes of the upper and lower moving frames 1 are both in line with the corresponding tower sections, and preliminary guidance is performed through the cooperation of the guide block 42 and the guide groove 421, so that the clamping plates 40 on the two moving frames 1 are opposite to each other up and down. As the external lifting equipment continues to place the upper tower section from top to bottom, the upper tower section and the moving frame 1 thereon continue to move downward, and the docking column 31 on the moving frame 1 continues to move downward and is inserted into the docking groove 310 of the lower clamping plate 40 for secondary guidance and limiting, guiding the precise docking of the upper and lower tower sections. At the same time, through the above method, the upper and lower moving frames 1 are connected to each other through the clamping plate 40, and at the same time, the plug-in between the guide column 300 and the guide cylinder 301 is cooperated to form a stable frame to ensure the stability during the docking process of the tower sections.

[0049] like Figure 1 and Figure 2As shown, the guide mechanism 3 also includes a side plate 32. Two left-right symmetrical side plates 32 are fixedly provided on the opposite back surfaces of the two movable frames 1. A sliding column 320 with an axis extending from left to right is passed through the side plate 32 for left-right sliding. A fitting plate 322 is fixedly provided on the opposite surfaces of the two adjacent sliding columns 320 on the left and right.

[0050] like Figure 1 and Figure 2 As shown, guide plates 33 are fixedly provided on both end surfaces of the bonding plate 322, and the two guide plates 33 on the same bonding plate 322 are symmetrical to each other, and the two guide plates 33 opposite to each other on the left and right are symmetrical to each other. Taking the guide plate 33 on the left front side as an example, the guide plate 33 is composed of a rectangular section and an inclined section from left to right, and the inclined section is inclined forward from left to right.

[0051] like Figure 1 and Figure 2 As shown, the guiding mechanism 3 also includes a pushing frame 34, the pushing frame 34 is fixedly arranged on the rectangular block 411, the pushing frame 34 is fixedly arranged on the pushing frame 34, the pushing plate 340 is slidably sleeved on the adjacent sliding column 320, the sliding column 320 is fixedly sleeved with a mounting plate 341 located between the fitting plate 322 and the pushing plate 340, and a spring 2 342 sleeved on the sliding column 320 is fixedly arranged between the mounting plate 341 and the pushing plate 340.

[0052] During operation, in the process of installing the mobile frame 1 on the tower section, the mounting plate 341 is manually moved so that the mounting plate 341 drives the sliding column 320 and the bonding plate 322 away from the stairs of the tower section, and the spring 2 342 is compressed. Then the mobile frame 1 is moved and the climbing wheel 22 on the mobile frame 1 presses the tower section under the action of the spring 1 230, and the mounting plate 341 is released. The elastic force generated by the compression of the spring 2 342 causes the mounting plate 341 to drive the sliding column 320 and the bonding plate 322 close to the stairs. During the movement of the bonding plate 322, the bonding plate 322 drives the guide plate 33 thereon to move synchronously. The inclined section of the guide plate 33 first contacts the stairs, so that the rectangular sections of the corresponding two guide plates 33 can cooperate with each other in the subsequent process.

[0053] Then, in the process of driving the pressing plate 40 to press the tower section, the rectangular block 411 approaches the tower section, and the rectangular block 411 drives the pushing plate 340 to move synchronously through the pushing frame 34, and the pushing plate 340 compresses the corresponding spring 2 342. The elastic force generated by the deformation of the spring 2 342 makes the mounting plate 341 drive the fitting plate 322 to approach the stairs through the sliding column 320, and the guide plate 33 continues to move with the fitting plate 322, and the rectangular section of the guide plate 33 gradually contacts the stairs, and finally the fitting plate 322 is close to the stairs, and the two rectangular sections of the guide plates 33 are They cooperate with each other and press against the stairs. Taking the stair position of the corresponding tower section as a reference, the axis of the mobile frame 1 is made to be collinear with the axis of the corresponding tower section through the fitting of the two fitting plates 322, and the circumferential angle of the tower section is locked with the mobile frame 1. Therefore, in the subsequent process of guiding the two mobile frames 1 to dock up and down, the docking process of the two mobile frames 1 can be used as a transition, so that the axes of the two tower sections are not only collinear but also aligned up and down, which ensures the accuracy of the connection and installation process of the two tower sections and avoids the problem of the upper and lower tower sections not being aligned and affecting the subsequent installation.
