Description

Technical Field

[0001] The present application belongs to the field of lifting machinery, and specifically relates to an introduction roller and a climbing device of a standard section. Background Art

[0002] The tower body of a tower crane is assembled from multiple standard sections. A tower crane generally increases or decreases the working height of the entire machine by adding or reducing standard sections through a climbing device. Specifically, it includes: lifting the standard section to the introduction platform, installing introduction rollers at the bottom of the standard section, and sliding the introduction rollers on the introduction beam to move the standard section from the introduction platform to the center of the tower body.

[0003] Patent CN202556037U-Tower crane standard section disassembly and assembly tool discloses an introduction roller suitable for bolt-connected standard sections. When in use, insert its connecting pin into the bolt sleeve hole at the bottom of the standard section, and rotate the connecting plate to insert the pressure-bearing boss under the cross bar at the bottom of the standard section. When disassembling, it is necessary to rotate the connecting plate back and forth toward the outside of the standard section so that the pressure-bearing boss is out of the cross bar at the bottom of the standard section, and then lift the connecting plate to remove the tower crane standard section disassembly and assembly tool. Then, for the tenon type standard section, since there is no above-mentioned bolt sleeve hole on the outside of the main chord of the standard section, the above-mentioned tower crane standard section disassembly and assembly tool cannot be used. In addition, after the standard section is introduced into the center of the tower body, the space between the standard section and the climbing device is compact; and when disassembling, it is necessary to rotate back and forth around the connecting pin, which easily causes the tower crane standard section disassembly and assembly tool to interfere with the climbing frame of the climbing device, resulting in difficulty in disassembly.

DETAILED DESCRIPTION

[0033] The specific implementation of the present application is described in detail below in conjunction with the accompanying drawings. It should be understood that the specific implementation described here is only used to illustrate and explain the present application, and is not used to limit the present application.

[0034] like Figures 1 to 3 As shown, a standard section introduction roller comprises:

[0035] The roller frame 1 is provided with an upper clamping plate 11 and a lower clamping plate 12 arranged in the vertical direction and fixed by a side plate 16, the lower clamping plate 12 can support the web 72 of the standard section 7, and the upper clamping plate 11 and the lower clamping plate 12 are formed with a first clamping port 13 individually or in combination, and the first clamping port 13 can clamp the main chord 71 of the standard section 7;

[0036] The rotating shaft 2 is fixed on the roller frame 1 and extends outward from the roller frame 1;

[0037] The roller 3 is sleeved on the rotating shaft 2 and is located outside the roller frame 1 .

[0038] In the present application, the introduction roller is clamped at the bottom of the standard section 7 to support and enable the standard section 7 to move in a preset direction. Among them, the lower clamping plate 12 abuts against the web 72 of the standard section 7 to support the standard section 7; the shape of the first bayonet 13 matches the outer contour of the main chord 71 of the standard section 7, firmly clamps the main chord 71 of the standard section 7 to limit the relative position of the introduction roller and the standard section 7; the roller 3 rotates freely on the rotating shaft 2 so that the standard section 7 can move in a preset direction. The way the first bayonet 13 is clamped with the main chord 71 has nothing to do with the specific structure of the standard section 7. It only needs to match the shape of the first bayonet 13 and the main chord 71. It can be applied to standard sections 7 of different connection types and has a wide range of uses. In addition, the installation and disassembly process only requires the introduction roller to be linearly moved relative to the standard section 7, without rotating back and forth, with low requirements for operating space, and can avoid interference with external devices. The disassembly and assembly are flexible and convenient.

[0039] Specifically, the upper clamping plate 11 abuts against one side of the main chord 71, and the lower clamping plate 12 abuts against the other side of the main chord 71, and the upper clamping plate 11 and the lower clamping plate 12 are combined to form a first clamping opening 13. That is, the clamping opening shape of the upper clamping plate 11 or the lower clamping plate 12 is half the shape of the first clamping opening 13. While realizing the high-low combination clamping, the upper clamping plate 11 and the lower clamping plate 12 reduce their own size and weight, making them easy to carry and convenient to disassemble and assemble, and also reducing the probability of interference between the roller frame 1 and the end of the standard section 7.

[0040] like Figure 4 , Figure 5 As shown, optionally, the upper clamping plate 11 and / or the lower clamping plate 12 abut against both sides of the main chord 71, and the upper clamping plate 11 and the lower clamping plate 12 are combined to form a first clamping port 13. That is, the clamping port shape of the upper clamping plate 11 or the lower clamping plate 12 is the shape of the entire first clamping port 13. The upper clamping plate 11 or the lower clamping plate 12 can clamp the main chord 71 alone, and the two are clamped in a high-low combination, further strengthening the clamping effect of the first clamping port 13.

[0041] Specifically, the roller frame 1 further includes a baffle 14 located between the upper clamping plate 11 and the lower clamping plate 12 . The baffle 14 and the lower clamping plate 12 are combined to form a second clamping opening 15 . The second clamping opening 15 can clamp the web 72 of the standard section 7 .

[0042] Furthermore, the clamping direction of the first clamping opening 13 is the same as the rolling direction of the roller 3 , and the clamping direction of the second clamping opening 15 is perpendicular to the rolling direction of the roller 3 and is located on the inner side of the roller frame 1 .

[0043] In the present application, when installing the introduction roller, it is first clamped on the web 72 of the standard section 7 from the outside of the standard section 7 through the second clamping hole 15 to prevent the introduction roller from falling; then the introduction roller is pushed along the web 72 and clamped on the main chord 71 of the standard section 7 through the first clamping hole 13. The clamping process of the introduction roller does not need to be carried all the time, which is labor-saving and convenient.

[0044] Specifically, the roller frame 1 further includes a reinforcing plate 17 , which is perpendicular to the side plate 16 and connected to the side plate 16 , the upper clamping plate 11 and the lower clamping plate 12 , respectively.

[0045] Specifically, the roller frame 1 further includes a handle 18 located on the surface of the upper clamping plate 11 , and the handle 18 is used to lift the introduction roller to facilitate the installation of the introduction roller.

[0046] In some embodiments, the roller carrier 1 is formed by welding the upper clamping plate 11, the lower clamping plate 12, the baffle plate 14, the side plate 16, the reinforcing plate 17, etc. to each other. The upper clamping plate 11, the side plate 16 and the lower clamping plate 12 form a "C" shape. The upper clamping plate 11 is located at the upper part of the "C" shape, the side plate 16 is located at the side of the "C" shape, and the lower clamping plate 12 is located at the lower part of the "C" shape. Two reinforcing plates 17 are located in the middle of the "C" shape and are arranged at a certain distance. Three surfaces of the reinforcing plate 17 are respectively connected to the upper clamping plate 11, the side plate 16 and the lower clamping plate 12 to play a reinforcing role. The upper clamping plate 11 and the lower clamping plate 12 are combined to form a first clamping opening 13 which is U-shaped in top view to adapt to the contour shape of the main chord 71. The baffle plate 14 is strip-shaped and is respectively arranged on the reinforcing plate 17 and extends to the right side of the "C" shape, parallel to the lower clamping plate 12. The handle 18 is in a "∩" shape and is welded on the upper surface of the upper clamping plate 11.

[0047] Specifically, the introduced roller further includes a pin 4 inserted between the lower clamping plate 12 and the web member 72 of the standard section 7. The pin 4 is used to limit the relative position between the introduced roller and the standard section 7.

[0048] Specifically, the introduced roller further includes a chain 5. One end of the chain 5 is connected to the roller carrier 1, and the other end is connected to the pin 4. The chain 5 is used to prevent the pin 4 from being lost or dropped.

[0049] In some embodiments, one end of the rotating shaft 2 passes through the side plate 16 of the rolling frame and is perpendicular to the clamping direction of the first clamping opening 13. One side of the roller 3 is provided with a flange and is installed on the rotating shaft 2 through a bearing. Its axial position is adjusted by a bushing sleeved on the rotating shaft 2, and axial fastening is completed by a fastener on the end face of the rotating shaft 2. The pin 4 can be inserted into the pin holes on the lower clamping plate 12 of the rolling frame and the web member 72 of the standard section 7. One end of the chain 5 is connected to the handle 18 of the roller carrier 1 through a spring hook, and the other end is connected to the end of the pin 4.

[0050] As Figure 6 、 Figure 8 shown, a climbing device 6 for a standard section includes an introduction platform 61, a guide rail 62 and the above-mentioned introduced roller; the guide rail 62 is arranged on the introduction platform 61; the roller carrier 1 is clamped on the bottom of the standard section 7; the roller 3 is located outside the standard section 7 and can roll on the guide rail 62.

[0051] In some embodiments, the climbing device 6 is installed on the outside of the tower body. The standard section 7 is hoisted from the ground and placed on the introduction platform 61 of the climbing device 6. After the introduced roller is installed, the standard section 7 moves integrally along the guide rail 62 through the rolling of the roller 3 and is introduced into the center of the tower body.

[0052] In some embodiments, an introduction roller is clamped at the bottom of each main chord 71 of the standard section 7, with a total of 4 introduction rollers. The first clamping port 13 of the introduction roller is clamped with the main chord 71 of the standard section 7, and the upper surface of the lower clamping plate 12 is in contact with the web 72 of the standard section 7 to hold up the standard section 7 when it is introduced. The second clamping port 15 of the introduction roller is clamped with the web 72 of the standard section 7 to prevent the introduction roller from being separated from the standard section 7 during installation. The web 72 of the standard section 7 is provided with a pin hole, and the pin 4 of the introduction roller passes through the pin hole on the web 72 and is inserted into the pin hole of the lower clamping plate 12, which plays a limiting role and prevents the introduction roller from moving.

[0053] like Figure 7 As shown, specifically, a limiting clamping plate 611 is provided on one side of the guide rail 62 on the introduction platform 61 , and the limiting clamping plate 611 is used to lock the rolling of the roller 3 .

[0054] In some embodiments, the limiting card plate 611 is a right-angle plate with a U-shaped card slot, and one side of the limiting card plate 611 is hinged on the introduction platform 61. After the limiting card plate 611 is flipped upward, the U-shaped card slot engages the roller 3 to lock the rolling of the roller 3; the limiting card plate 611 is unlocked after flipping downward.

[0055] In some embodiments, the specific process of using the climbing device 6 to introduce the standard section 7 is as follows:

[0056] The tower crane hoists the standard section 7 from the ground to above the introduction platform 61 of the climbing device 6 .

[0057] The operator enters the interior of the hoisted standard section 7, lifts the handle 18 of the introduction roller, and clamps the second bayonet 15 of the introduction roller from the outside of the standard section 7 to the belly rod 72 at the lower end of the standard section 7, as shown in FIG. Fig. 9 Then, the first bayonet 13 of the introduction roller is clamped on the main chord 71 of the standard section 7, as shown in FIG. Fig. 9 Finally, insert the pin 4 of the introduction roller into the pin holes on the web bar 72 of the standard section 7 and the lower clamping plate 12 to prevent the introduction roller from sliding or falling. Repeat this step until the introduction rollers are clamped on the four main chords 71 ​​of the standard section 7.

[0058] The hoisted standard section 7 is placed in place, and the position of the standard section 7 is adjusted so that the roller 3 of the introduction roller falls on the guide rails 62 on both sides of the introduction platform 61, and the roller 3 of the introduction roller is locked using the limiting clamping plate 611.

[0059] When the climbing frame of the climbing device 6 is lifted to a space where a standard section 7 can be introduced, the operator releases the limit clamp 611, and then pushes the standard section 7. The introduction rollers support the standard section 7 and roll it to the center of the tower along the guide rails 62 on both sides of the introduction platform 61 to introduce the standard section 7 into the center of the tower.
