Description

Technical Field

[0001] The invention belongs to the technical field of sling deviation correction, and in particular relates to a guide wheel device with a sling deviation correction function. Background Art

[0002] Turbine rigid fast door is a series of door panels with multiple joints. The door rotates up and down with the reel above the door as the center. The drive motor for driving the door panel to rise and wind is located on the upper part of the door panel and drives the door panel through a chain. In order to reduce the load of the drive motor when the door panel rises, Figure 1 As shown, a sling shaft 01 for winding the sling 0 is coaxially arranged at both ends of the reel, and the movable end of the sling 0 is fixedly connected to one end of the spring 02 after being guided and tensioned by the guide wheel assembly 03, and the other end of the spring 02 is fixedly arranged at the bottom end of the door frame.

[0003] When the driving motor drives the door panel to descend and the reel rotates through the chain, the sling shaft 01 rotates accordingly, the sling 0 is wound and wound, and its movable end drives the spring 02 to stretch upward to store energy; when the driving motor drives the door panel to rise through the chain and the reel reverses its rotation, the sling shaft 01 reverses its rotation accordingly, the sling 0 unfolds, and at the same time, the energy stored in the spring 02 is finally transferred to the reel by pulling down the sling 0, thereby providing part of the power for the door panel to rise, thereby reducing the load-bearing burden of the driving motor when the door panel rises.

[0004] However, when the guide wheel assembly 03 guides the sling 0, under the action of friction, the sling will produce a certain offset on the guide wheel on the guide wheel assembly 03. This offset will cause the sling 0 to contact with the door frame components and wear. In severe cases, the sling 0 will break and the spring 02 may also be pulled out, causing the door body to be unable to operate.

[0083] Preferably, Figure 5 As shown, the first connecting end 211 and the second connecting end 212 are both provided with end stops 213 to prevent the first connecting end 211 from escaping from the first adjustment hole 11 and the second connecting end 212 from escaping from the first connecting hole 32 and the second adjustment hole 12 .

[0084] An annular groove 214 for mounting an end stop 213 is provided on both the first connecting end 211 and the second connecting end 212 , wherein the end stop 213 on the second connecting end 212 is not shown in the drawings.

[0085] Preferably, Figure 2 As shown, the first adjustment assembly includes an adjustment plate 3, an adjustment bolt 4, an adjustment nut 5, and a compression spring 6;

[0086] like Figure 4 As shown, the adjusting plate 3 is provided with a first connecting hole 32 and a second connecting hole 33 in sequence from front to back;

[0088] A third adjustment hole 151 is provided on the second side plate 15;

[0089] A fourth adjustment hole 131 is provided on the bottom plate 13;

[0090] The first connecting hole 32 cooperates with the second connecting end 212, the second connecting hole 33 is aligned with the third adjusting hole 151 and is assembled with a plug screw 7, wherein a nut 71 is provided at the screw end of the plug screw 7; the adjusting bolt 4 passes through the aligned fourth adjusting hole 131 and the third connecting hole 34 from bottom to top, the compression spring 6 is sleeved on the adjusting bolt 4 between the bottom plate 13 and the horizontal plate 31, and the adjusting nut 5 is assembled on the adjusting bolt 4 on the upper part of the horizontal plate 31.

[0091] The specific implementation of the guide wheel device with the sling deviation correction function in Example 1 is as follows:

[0092] In the present application, the adjusting plate 3 forms a lever structure with the driving screw 7 as the rotation fulcrum. When the adjusting nut 5 is tightened to press the horizontal plate 31, the front end of the adjusting plate 3 drives the second connecting end 212 to move upward around the driving screw 7, thereby causing the side of the guide wheel 2 close to the second connecting end 212 to move upward and be lifted; when the adjusting nut 5 is loosened, under the upward force of the compression spring 6, the horizontal plate 31 drives the rear end of the adjusting plate 3 to move upward around the driving screw 7, thereby prompting the second connecting end 212 to move downward, and realizing the downward movement of the side of the guide wheel 2 close to the second connecting end 212.

[0093] When using this application, if Figure 6 As shown, the guide wheel bracket 1 is fixed by connecting bolts 17 .

[0094] When the sling 0 deviates to the left, tighten the adjusting nut 5 and press down the horizontal plate 31, so that the front end of the adjusting plate 3 drives the second connecting end 212 to move upward along the second adjusting hole 12, so that the right side of the guide wheel 2 is raised. Figure 7 As shown; according to the rule that the belt runs high but not low, the sling 0 will gradually move to the right to correct the deviation. After the sling 0 returns to the middle position of the guide wheel 2, the guide wheel 2 is leveled by loosening the adjusting nut 5.

[0095] When the sling 0 deviates to the right, loosen the adjusting nut 5. Under the upward force of the compression spring 6, the horizontal plate 31 drives the rear end of the adjusting plate 3 to move upward around the plug screw 7, thereby causing the second connecting end 212 to move downward, so that the right side of the guide wheel 2 is lowered. Figure 8 As shown; according to the rule that the belt runs high but not low, the sling 0 will gradually move to the left to correct the deviation. After the sling 0 returns to the middle position of the guide wheel 2, the guide wheel 2 is leveled by tightening the adjusting nut 5.

[0096] Example 2:

[0097] like Figure 9As shown, a guide wheel device with a sling deviation correction function includes a guide wheel bracket 1 and a guide wheel 2 arranged on the guide wheel bracket 1;

[0098] The guide wheel 2 is internally coaxially rotated with the guide wheel shaft 21. Specifically, the guide wheel 2 and the guide wheel shaft 21 are rotated together via a bearing.

[0099] like Figure 11 As shown, the guide wheel bracket 1 is provided with a first adjustment hole 11 and a second adjustment hole 12; the second adjustment hole 12 is a strip-shaped hole, and the length direction of the second adjustment hole 12 is the vertical direction;

[0100] The first connecting end 211 of the guide wheel shaft 21 is matched with the first adjustment hole 11, and the second connecting end 212 of the guide wheel shaft 21 is matched with the second adjustment hole 12;

[0101] The guide wheel bracket 1 is provided with a first adjustment component for adjusting the height of the second connecting end 212 in the second adjustment hole 12 .

[0102] Preferably, Figure 11 As shown, the first adjustment hole 11 is a strip-shaped hole, and the length direction of the first adjustment hole 11 is the front-to-back direction;

[0103] The guide wheel bracket 1 is provided with a second adjustment component for adjusting the front and rear position of the first connecting end 211 in the first adjustment hole 11 .

[0104] Specifically, the center point of the second adjustment hole 12 is located on the central axis of the first adjustment hole 11 .

[0105] Specifically, the width of the first adjustment hole 11 is greater than the diameter of the first connection end 211.

[0106] The width of the second adjustment hole 12 is greater than the diameter of the second connecting end 212 .

[0107] Such a configuration is to adapt to changes in the height position of the second connection end 212 and the front-to-back position of the first connection end 211 .

[0108] Preferably, Figure 10 As shown, the first adjustment assembly includes a first adjustment plate 8 and a first adjustment screw 81;

[0109] The first adjustment plate 8 is matched with the second connection end 212 of the guide wheel shaft 21 through the first assembly hole;

[0110] The first adjustment plate 8 is hingedly connected to the guide wheel bracket 1 via a first hinge shaft 82;

[0111] The first adjusting screw 81 is threadedly engaged with the guide wheel bracket 1 and extends in the vertical direction. The top end of the first adjusting screw 81 contacts the first push plate 83 on the first adjusting plate 8 .

[0112] Specifically, the first assembly hole is located between the first hinge shaft 82 and the first push plate 83 .

[0113] Preferably, Figure 10 As shown, the second adjustment assembly includes a second adjustment plate 9 and a second adjustment screw 91;

[0114] The second adjustment plate 9 is matched with the first connecting end 211 of the guide wheel shaft 21 through the second assembly hole;

[0115] The second adjustment plate 9 is hingedly connected to the guide wheel bracket 1 via a second hinge shaft 92;

[0116] The second adjusting screw 91 is threadedly engaged with the guide wheel bracket 1 and extends in the front-to-back direction. The front end of the second adjusting screw 91 contacts the second push plate 93 on the second adjusting plate 9 .

[0117] Specifically, the second assembly hole is located between the second hinge shaft 92 and the second push plate 93 .

[0118] The specific implementation of the guide wheel device with the sling deviation correction function in Example 2 is as follows:

[0119] In the present application, the first adjustment plate 8 forms a lever structure with the first hinge shaft 82 as the rotation fulcrum. When the first adjustment screw 81 is rotated upward, the top end of the first adjustment screw 81 pushes the first push plate 83, causing the first adjustment plate 8 to rotate upward about the first hinge shaft 82, driving the second connecting end 212 to move upward, thereby causing the side of the guide wheel 2 near the second connecting end 212 to move upward and be raised. When the first adjustment screw 81 is rotated downward, the second connecting end 212 moves downward under the weight of the guide wheel 2 and the force of the sling 0, causing the side of the guide wheel 2 near the second connecting end 212 to move downward. Thus, the height adjustment of the side of the guide wheel 2 near the second connecting end 212 is achieved through the configuration of the first adjustment assembly.

[0120] In the present application, the second adjustment plate 9 forms a lever structure with the second hinge shaft 92 as the rotation fulcrum. When the second section screw 91 is rotated forward, the front end of the second adjustment screw 91 pushes the second push plate 93, causing the second adjustment plate 9 to rotate forward around the second hinge shaft 92, driving the first connection end 211 forward, thereby causing the side of the guide wheel 2 near the first connection end 211 to move forward. When the second adjustment screw 91 is rotated backward, under the action of the sling 0, the first connection end 211 moves backward, causing the side of the guide wheel 2 near the first connection end 211 to move backward. Thus, the front-to-back position of the guide wheel 2 near the first connection end 211 can be adjusted by setting the second adjustment assembly.

[0121] When using this application, if Figure 12 As shown, the guide wheel bracket 1 is fixed by the auxiliary connecting member 10, but the guide wheel device in Example 2 of the present application is not limited to the attached Figure 12 The rolling door structure in the.

[0122] When the sling 0 deviates to the left, rotate the first adjusting screw 81 downward and the second screw 91 forward to make the left side of the guide wheel 2 drop down and the right side of the guide wheel 2 move forward. According to the rule that the belt runs high but not low, the sling 0 will gradually move to the right and correct the deviation. After the sling 0 returns to the middle position of the guide wheel 2, adjust the guide wheel 2 to achieve horizontality.

[0123] When the sling 0 deviates to the right, rotate the first adjusting screw 81 upward and the second screw 91 backward to raise the left side of the guide wheel 2 and move the right side of the guide wheel 2 backward. According to the rule that the belt runs high but not low, the sling 0 will gradually move to the left and correct the deviation. After the sling 0 returns to the middle position of the guide wheel 2, adjust the guide wheel 2 to achieve horizontality.

[0124] Example 3:

[0125] Based on Example 1 or Example 2, the guide wheel 2 is a concave wheel structure, a flat wheel structure, or a cam structure. The guide wheel 2 in this application adopts a concave wheel structure, a flat wheel structure, or a cam structure, but is not limited to these three structures. Other structures that can achieve the guiding function are also acceptable.

[0126] like Figure 13 As shown, the concave wheel structure is thin in the middle and thick at both ends, and the generatrix of the outer side surface of the guide wheel 2 of the concave wheel structure is an arc structure.

[0127] like Figure 14 As shown, the outer side surface of the guide wheel 2 with a flat wheel structure is a cylindrical surface.

[0128] like Figure 15 As shown, the cam structure is thick in the middle and thin at both ends, and the generatrix of the outer side surface of the guide wheel 2 of the cam structure is an arc structure.

[0129] Among them, the correction function of the guide wheel with concave wheel structure and cam structure is better than that of the guide wheel with flat wheel structure.

[0130] Although the above describes the specific embodiments of the present invention in conjunction with the accompanying drawings, it is not a limitation of the present invention. Those skilled in the art should understand that various modifications or variations that can be made by those skilled in the art on the basis of the technical solution of the present invention without any creative work are still within the scope of protection of the present invention.
