Description

Technical Field

[0001] The present invention belongs to the field of construction machinery, and particularly relates to a tower crane support structure and a replacement method that facilitate the rapid replacement of a sealing ring. Background Art

[0002] Tower cranes are commonly used construction machinery on construction sites. Tower cranes can transport construction tools or building materials from one place to another. Mainly, the horizontal arm and the support column of the tower crane are rotatably arranged relative to each other, which can ensure the working radius of the tower crane.

[0003] As the construction period progresses, the tower crane can be stacked layer by layer. The sealing ring at the slewing bearing of the tower crane is easily damaged during operation. The installation structure of the tower crane slewing bearing seat can be referred to in the attached drawings of the specification Figure 1 and the attached drawings of the specification Figure 2 As shown. Due to long-term use, not only the quality of the sealing ring itself is damaged, but also there is a lot of wear due to long-term operation. If the sealing ring at the slewing bearing is damaged, it is very easy to cause oil leakage. The leaked oil will flow to the staircase of the tower crane, and it is very easy for people to slip when going up and down. For a tower crane operating at high altitude, slipping of people is a very high safety hazard. Therefore, the tower crane needs to be carefully maintained every time it is used or after use.

[0004] When a potential hazard of the sealing ring is found, the current practice is to directly replace it. However, for a very high tower crane, replacing the sealing ring requires removing each unit section of the tower crane one by one until the entire tower crane is completely removed. The entire replacement process takes 1 - 2 days, so the replacement efficiency is very low. Therefore, in order to improve the replacement efficiency of the sealing ring, a sealing ring replacement method different from the traditional one and a tower crane support structure that can replace the sealing ring are needed. Summary of the Invention

[0005] The purpose of the present invention is to address the above problems, and provide a tower crane support structure and a replacement method that facilitate the rapid replacement of a sealing ring, which can directly replace the sealing ring without dismantling the tower crane, thereby improving the replacement efficiency.

[0006] To achieve the above purpose, the technical solution adopted by the present invention is: a tower crane support structure that facilitates the rapid replacement of a sealing ring, including a first support and a second support that are rotatably arranged relative to each other. A gap is provided between the first support and the second support, and a sealing member is detachably filled in the gap.

[0007] It further includes a guiding component and a clamping component that facilitate filling the sealing member into the gap. The guiding component and the clamping component are relatively arranged on the first support and the second support on both sides of the gap.

[0008] One end of the seal is fixed to the clamping assembly. After the other end passes through the guiding assembly, it is pressed into the gap by the guiding assembly. When the first support and the second support rotate relative to each other, the seal is completely filled into the gap.

[0009] As a further improvement of the above technical solution, the guiding assembly includes a plurality of first guiding members arranged oppositely. A second guiding member is fixedly arranged on the lower side of the first guiding member. The first guiding member and the second guiding member are in contact with and guide the seal, and guide the seal into the gap.

[0010] As a further improvement of the above technical solution, a support member is movably connected between the plurality of first guiding members, and an adjusting mechanism for facilitating the adjustment of the distance is arranged between the first guiding members.

[0011] As a further improvement of the above technical solution, a pushing mechanism for arranging the seal is arranged on the first guiding member, which can drive the first guiding member and the second guiding member to move up and down.

[0012] The pushing mechanism includes an eccentric roller rotatably arranged on the first guiding member near the side extending into the gap, and also includes a pushing member located above the first guiding member and elastically pushing the first guiding member to move up and down.

[0013] As a further improvement of the above technical solution, the second guiding member includes a notch with an opening facing outwards on the side.

[0014] When conveying the seal, along the conveying direction, there is a tendency for the plurality of second guiding members to gradually shrink and squeeze the seal towards the middle.

[0015] As a further improvement of the above technical solution, the clamping assembly includes a sliding seat. A connecting slider moving along the diameter direction of the first support and the second support is slidably arranged on the sliding seat. A connecting groove for facilitating the mutual fixation with the seal is arranged on the connecting slider.

[0016] As a further improvement of the above technical solution, docking blocks are respectively arranged at both ends of the seal, and the docking blocks protrude upwards from the top surface of the seal.

[0017] A plurality of docking holes for facilitating the docking of the seal are arranged on the docking blocks, and a groove is arranged on the upper surface of the docking block protruding from the top surface of the seal.

[0018] As a further improvement to the above technical solution, a pushing assembly is further included, wherein the pushing assembly includes a roller that can roll in contact with the first support or the second support, a plurality of cams are fixedly mounted on the rotating shaft of the roller, and a push rod is disposed below the cam to contact the cam and push the seal downward into the gap. The method for replacing a sealing ring using a tower crane support structure that facilitates rapid replacement of the sealing ring is characterized by comprising the following steps:

[0019] 1) Arrange the sealing ring: insert the sealing member into the guide assembly, and clamp one end of the inserted sealing member and the clamping assembly together;

[0020] 2) Installation: Control the first support and the second support to rotate relative to each other, and the guide assembly and the clamping assembly follow the rotation of the first support and the second support, and gradually increase the distance between them, so as to guide the seal into the gap between the first support and the second support;

[0021] 3) Tighten and fix: Remove the two ends of the seal from the clamping assembly and the guide assembly respectively, and connect them together. Use bolts and other fasteners to fix the joints. After fixation, the seal becomes a ring, and the seal that is raised from the gap is inserted into the gap.

[0022] Beneficial effects of the present invention:

[0023] 1. The present invention provides a tower crane support structure and a replacement method that are convenient for quickly replacing a sealing ring. The sealing member is arranged into a strip shape and is filled with the assistance of a guide assembly and a clamping assembly. One end of the sealing member is fixed by the clamping assembly. The sealing member is guided between the guide assembly and the sealing member so that the sealing member can be inserted into the gap between the first support and the second support. During the rotation of the first support, the sealing member can be filled into the gap. Therefore, the sealing member can be quickly installed without disassembling the tower crane support column, thereby greatly improving the efficiency of sealing member replacement and reducing costs.

[0024] 2. When filling the seal, through the rolling contact between the eccentric roller and the top surface of the second support, the first guide member and the second guide member can be pushed by the pushing member to arrange the seal in an up and down manner. Then, when filling the seal, the seal arranged up and down can be straightened by the tension or self-generated deformation generated on the seal during the arrangement process, so that the last filled seal can be in a straight state, and the seal will not be deformed longer due to excessive pulling on the seal, resulting in subsequent failure to connect normally.

[0025] 3. The push assembly can automatically press the protruding part down into the gap after the seal is filled into the gap, which is convenient and quick. BRIEF DESCRIPTION OF THE DRAWINGS

Specific Embodiment

[0049] To enable those skilled in the art to better understand the technical solution of the present invention, the present invention will be described in detail below with reference to the accompanying drawings. The description in this part is only exemplary and explanatory, and should not have any restrictive effect on the protection scope of the present invention.

[0050] Embodiment 1:

[0051] As shown in the attached Figure 1-19 of the specification, it is Embodiment 1 of the present invention. As a specific embodiment of the present invention, the specific structure of the present invention is: a tower crane support structure and a replacement method for facilitating the quick replacement of the sealing ring, including a first support 10 and a second support 11 that are rotatably arranged with each other. Referring to the attached Figure 1 , 2 shown, the mounting seat connected to the top of the first support 10 is an inner support fixedly arranged with the cross arm of the tower crane, and the bottom of the second support 11 is an outer support fixedly arranged with the support column of the tower crane. The attached Figure 1Only the support part at the slewing position of the tower crane is shown, in which the second support 11 is fixed to the support column of the tower crane. When the cross arm swings, the first support 10 moves with the cross arm. A gap is provided between the first support 10 and the second support 11, and a sealing member 12 can be detachably filled in the gap. The sealing member 12 is an O-ring, which can be referred to in the attached Figure 5 , 6 shown, which is formed by directly butting the two ends;

[0052] It also includes a guiding component 13 and a clamping component 14 for facilitating the filling of the sealing member 12 into the gap. The guiding component 13 mainly wraps the sealing member 12 and guides the moving direction of the sealing member 12. The sealing member 12 passes through and is pressed into the gap under the guidance of the guiding component 13. The clamping component 14 mainly clamps and fixes one end of the sealing member 12. When the guiding component 13 moves, it is convenient for the sealing member 12 to continuously enter the guiding component 13. The guiding component 13 and the clamping component 14 are relatively arranged on the first support 10 and the second support 11 on both sides of the gap. Specifically, the guiding component 13 can be fixedly arranged on the first support 10, and the clamping component 14 can be fixedly arranged on the second support 11. Or the guiding component 13 can be fixedly arranged on the second support 11, and the clamping component 14 can be fixedly arranged on the first support 10. In this embodiment, it is selected to fixedly arrange the guiding component 13 on the first support 10 and the clamping component 14 on the second support 11. Such a setting is because during the rotation of the tower crane cross arm, by starting the motor fixed to the mounting seat of the first support 10, when the motor starts, the gear connected to its output shaft rotates. This gear meshes with the gear outside the second support 11, which can drive the first support 10 to rotate. Then, when the first support 10 rotates, it drives the guiding component 13 to rotate, enabling the sealing member 12 to continuously enter the guiding component 13 and be filled into the gap. When filling the sealing member 12, through the self-rotation of the tower crane, the sealing member 12 can be brought in, without the need to disassemble the entire tower crane, greatly accelerating the filling rate.

[0053] As shown in the attached Figure 11 , 12, as shown in FIGS. 13, 14, 15, 16, 17, 18, and 19, further optimized on the basis of the above embodiments: The guiding assembly 13 includes a plurality of first guiding members 131 arranged oppositely. The first guiding member 131 is a guiding piece with an arc-shaped guiding surface, and there are two symmetrically arranged first guiding members 131. A second guiding member 132 is fixedly arranged below the first guiding member 131. A part of the first guiding member 131 and the second guiding member 132 can extend into the gap between the first support 10 and the second support 11. Among them, there are also two symmetrically arranged second guiding members 132. A notch 1321 with an outward-facing side opening is provided on the second guiding member 132; when the two second guiding members 132 are symmetrically arranged for use, ensure that the notch 1321 faces the middle (refer to the arrangement method of the two second guiding members 132 in the attached drawings of the specification); as shown in the attached drawings of the specification, as another embodiment of the first guiding member 131 and the second guiding member 132, the docking block 121 and the second guiding member 132 are arranged as inclined flat plates; Figure 4 in the attached drawings of the specification; as shown in the attached drawings of the specification, Figure 19 , as another embodiment of the first guiding member 131 and the second guiding member 132, the docking block 121 and the second guiding member 132 are arranged as inclined flat plates;

[0054] The first guiding member 131 and the second guiding member 132 are in contact with the sealing member 12 to guide the sealing member 12. That is, when the sealing member 12 moves within the first guiding member 131 and the second guiding member 132, it can enter the gap between the first support 10 and the second support 11 along the shapes of the second guiding member 132 and the first guiding member 131, as shown in the attached drawings of the specification. Figure 12 As shown, when the first guiding member 131 and the second guiding member 132 move backward, the sealing member 12 fills down into the gap between the first support 10 and the second support 11.

[0055] When transporting the sealing member 12, along the transport direction, there is a tendency for the plurality of second guiding members 132 to gradually squeeze the sealing member 12 towards the middle (refer to the attached drawings of the specification), Figure 16 and 17 ). The second guiding member 132 not only has an arc surface that extends downward and obliquely, but also has as shown in the attached drawings of the specification, Figure 17As shown, when two second guide members 132 are arranged symmetrically, they have an inclination towards the middle position. In this way, the distance between the inlet ends of the two second guide members 132 is large, and the distance between the outlet ends is small. Therefore, when the two second guide members 132 are used symmetrically, the seal 12 entering the second guide members 132 can be squeezed and deformed towards the middle, and then can smoothly enter the gap between the first support 10 and the second support 11; A connecting piece with a "C" - shaped structure is fixedly arranged on the first guide member 131. A support member 133 is movably connected between the first guide members 131. The support member 133 is a support cylindrical rod. Two connecting seats are movably arranged on the support member 133. One of the connecting seats facing the outside is fixedly arranged with the support member 133, and the connecting seat located inside can slide and rotate relative to the support member 133, and the two connecting seats are fixedly arranged with the connecting piece. In this embodiment, a support seat is rotatably arranged at one end of the support member 133, and the support seat and the first support 10 are detachably arranged and are installed on the first support 10 during use. An adjusting mechanism for facilitating the adjustment of the distance between the two is arranged between the first guide members 131. In this embodiment, the adjusting mechanism includes a screw rod arranged between the two connecting seats. The screw rod is rotatably arranged with the outside connecting seat and is threadedly connected with the inside connecting seat. A knob for facilitating the rotation of the screw rod is arranged at the outer end of the screw rod. When the seal 12 needs to be installed on the first guide member 131 and the second guide member 132, the screw rod can be adjusted first to make the connecting seat move towards the support seat side, so as to open the gap between the two first guide members 131 and the two second guide members 132, facilitating the sleeving of the seal 12 on the second guide member 132 and the first guide member 131. Then, the screw rod is rotated to reduce the distance between the two first guide members 131 and the two second guide members 132, which can play a role in squeezing the seal 12 and facilitating its filling into the gap between the first support 10 and the second support 11.

[0056] A pushing mechanism for arranging the seal 12 is arranged on the first guide member 131, which can drive the first guide member 131 and the second guide member 132 to move up and down. The pushing mechanism includes an eccentric roller 134 rotatably arranged on the first guide member 131. The eccentric roller 134 is located on the first guide member 131 near the side extending into the gap between the first support 10 and the second support 11. In this embodiment, the eccentric roller 134 can be in contact with the surface of the second support 11. It also includes a pushing member 135 that elastically pushes the first guide member 131 to move up and down downward above the first guide member 131. In this embodiment, two pushing members 135 are symmetrically arranged. The pushing member 135 is specifically a lever that can be in contact with the connecting piece on the top surface of the first guide member 131 (refer to the attached Figure 11) The two toggle levers are fixedly connected by a rotating rod. The rotating rod passes through the support base connected to the support member 133 and is rotatably arranged with the support base. A hook is fixedly arranged at one end of the rotating rod. The hook is arranged at the end of the end passing through the support base. And a short cylindrical pin is arranged at the bottom of the support base. A spring is arranged between the cylindrical pin and the hook. The spring can pull the hook, so that the rotating rod drives the pushing member 135 to rotate, and further can ensure that the pushing member 135 is always in contact with the connecting piece;

[0057] When replacing the seal 12, the support base can be driven to rotate together by the first support 10, so that the eccentric roller 134 rolls on the top surface of the second support 11. Under the continuous downward elastic pressing of the pushing member 135, the first guide member 131 and the second guide member 132 can extend into one end of the interval between the first support 10 and the second support 11 and move in an oscillating manner. Furthermore, when filling the seal 12, the seal 12 can be filled in the interval in a wave-like form (as shown in the attached drawings of the specification) Figure 18 In this way, when filling, through the pulling force of the seal 12 and the self-deformation of the seal 12, the bent seal 12 can be overcome. Furthermore, the finally filled seal 12 is arranged in the interval in a straight manner, so that the seal 12 will not undergo large deformation during filling, ensuring that the seal 12 can exactly fill the interval and will not be too long due to the deformation of the seal 12. After filling is completed, the seal 12 can be manually arranged neatly.

[0058] As shown in the attached drawings of the specification Figure 3 、 4 、5, 6, on the basis of the above embodiments, further optimization is as follows: The clamping assembly 14 includes a sliding seat 141. In this embodiment, the sliding seat 141 is fixedly arranged on the top surface of the second support 11. A connecting slider 142 that moves along the diameter direction of the first support 10 and the second support 11 is slidably arranged on the sliding seat 141. A fastening bolt that is threadedly connected to the connecting slider 142 is arranged on the connecting slider 142. A connecting groove 143 that is convenient for fixing with the seal 12 is arranged on the connecting slider 142. When filling the seal 12, by fixing the end of the seal 12 in the connecting groove 143, one end of the seal 12 is fixed to the second support 11. After the first support 10 rotates one circle, the seal 12 can be arranged around the gap between the second support 11 and the first support 10 for one circle.

[0059] As shown in the attached drawings of the specification Figure 1 、 2, 7, 8, 9, as shown in the first support 10, based on the above embodiments, further optimized: the seal 12 is in an "I" - shaped structure. The upper horizontal structure can contact the first guide 131, and the lower horizontal structure can contact the second guide 132. Docking blocks 121 are respectively arranged at both ends of the seal 12, and the docking blocks 121 protrude upward from the top surface of the seal 12;

[0060] A number of docking holes 122 for facilitating the docking of the seal 12 are arranged on the docking blocks 121. After the seal 12 is arranged within the interval, bolts are passed through the docking holes 122 for fastening. A groove 123 is arranged on the upper surface of the docking block 121 protruding from the top surface of the seal 12. When the groove 123 can be filled into the interval, it is inserted into the connection groove 143 and fixed with the clamping assembly 14.

[0061] Embodiment 2:

[0062] As shown in the instruction manual appendix Figure 20 , 21 , 22, which is Embodiment 2 of the present application. This embodiment is a further improvement based on Embodiment 1: The present invention further includes a pressing assembly 15. The pressing assembly 15 includes rollers 151 that can roll and contact with the first support 10 or the second support 11. In this embodiment, the rollers 151 are in contact with the second support 11. A support platform for rotatably setting with the rollers 151 is arranged on the first support 10. A cavity is arranged inside the support platform. The rotating shaft of the roller 151 penetrates through the cavity. A number of cams 152 are fixedly arranged on the rotating shaft of the roller 151. A push rod 153 that contacts the cam 152 below and presses the seal 12 downward into the gap is arranged below the cam 152. A spring for pushing the push rod 153 to rebound upward is arranged below the push rod 153. The push rod 153 is slidably arranged with the support platform and penetrates through the cavity. When filling the seal 12, the first support 10 rotates relative to the second support 11, which can drive the rollers 151 to rotate, and then drive the cams 152 to rotate, thereby pushing the push rod 153 to move in the up - down direction. When the push rod 153 moves up and down, it can squeeze the filled seal 12 downward, and further squeeze the unfilled seal 12 downward to be filled.

[0063] A method for replacing the seal ring using a tower crane support structure that facilitates the quick replacement of the seal ring includes the following steps:

[0064] 1) Arranging the sealing ring: First, manually remove the damaged sealing ring from the gap between the first support 10 and the second support 11. By turning the screw, increase the gap between the first guide member 131 and the second guide member 132. Then, insert the sealing member 12 onto the first guide member 131 and the second guide member 132, and pull out the end of the sealing member 12. Insert the groove 123 into the connecting groove 143 to fix it. The pulled-out end of the sealing member 12 and the clamping assembly 14 are clamped together. The second guide member 132 and the first guide member 131 drive the sealing member 12 to extend into the gap, so that the eccentric roller 134 contacts the top surface of the second support 11. Prepare to install the sealing member 12.

[0065] 2) Installation: Control the electric starter on the mounting seat on the first support 10. After the motor is started, it drives the gear on the output shaft to rotate, thereby making the first support 10 and the second support 11 rotate relative to each other. The guide assembly 13 and the clamping assembly 14 follow the first support 10 and the second support 11 to rotate relative to each other, and gradually increase the distance between them. During the rotation of the first support 10, the eccentric roller 134 can be made to roll on the second support 11, thereby driving the first guide 131 and the second guide 132 to swing up and down, and arrange the seal 12 in the gap. After the first support 10 rotates one circle, the seal 12 can be introduced into the gap between the first support 10 and the second support 11.

[0066] 3) Tightening and fixing: After the first support 10 rotates one circle, the two ends of the seal 12 are removed from the clamping assembly 14 and the guide assembly 13 respectively, and connected together. The joints are fixed with fasteners such as bolts. The fixed seal 12 becomes annular, and the seal 12 that is raised from the gap is inserted into the gap. The seal 12 can be replaced without disassembling the tower crane support column.
