The reason for failure of dynamic hoist mechanism and solutions:

調(diào)整卷揚機制動器的過程中時常遇到太緊放不開，或太松抱不住的狀況，那么這事什么原因引起的呢？又該怎樣進行解決呢？

Hoister brake adjustment process often encountered too tight or too loose put not to open, not hold status, so that what reason causes? And how to solve?

(1)制動輪的袖中心與間瓦中心相對誤差太大(不允許大于3毫米)。這是由于檢修后的減速器安裝有誤差，使制動輪的位置改紀造成一例閘瓦張得九一側(cè)闖瓦張不開。當(dāng)把制動輪校準在兩個閘瓦的中心時，這一故障就可消除。

(1) the brake wheel sleeve center and the relative error between tile center is too large (no more than 3 mm). This is because after the repair reducer installation error, so that the brake wheel position change caused by a brake shoe Ji Zhang Dejiu side into the tile does not open. When the brake wheel alignment in the two brake shoe centre, this failure can be eliminated.

(2)閘瓦與制動輪的中心線傾斜。當(dāng)卷揚機減速器和劃動杠桿系統(tǒng)(閘架)安裝位置不正確時，就會造成間瓦與制動輪局部接隊使閉瓦抱不緊制動輪。在這種情況下，調(diào)得緊一些就會出現(xiàn)閘瓦不能完全松離制動輪的現(xiàn)象，使制動輪受摩擦而產(chǎn)生高熱。要求閘瓦在松開時，閘瓦與制動輪的傾斜度或不平度不得超過制動輪寬度的千分之一。

(2) tilting center line brake shoes and brake wheel. When the device and paddling lever system of hoist reducer (gate frame) installation position is not correct, it will cause between the tile and the brake wheel connected with the local team closed tile holding not tighten wheel. In this case, adjustable tight shoes can not completely loose will appear from phenomenon of the brake wheel, brake wheel to generate heat by friction. Requirements in the brake shoe, brake shoe and brake wheel tilt or roughness must not exceed the width of the brake wheel 1/1000.

(3)由于制動器的各銷軸與軸孔磨損嚴重，增大了調(diào)動電磁鐵的無效行程(空行程)，而有效行程減小。

(3) the pin brake shaft and shaft hole wear, increase the invalid stroke to mobilize the electromagnet (stroke), and reduce the effective stroke.

(4)制動輪磨損后，在重新加工時造成誤差。

(4) the brake wheel wear, causing the error in the re processing.

(5)卷揚機由于調(diào)整不合理，制動電磁鐵行程太小。這種情況常發(fā)生在只調(diào)拉桿沒調(diào)立桿的緣故。

(5) for adjusting the unreasonable hoist, braking electromagnet travel too small. This situation often occurs in the only adjustable pull rod no adjustable pole.

(6)新?lián)Q的調(diào)節(jié)拉棟加工尺寸不正確。

(6) the new regulating tension building processing size is not correct.

(7)主彈簧未受力或調(diào)整螺絲(頂絲)調(diào)整不合適，使間瓦一例張得多，一例張得少。

(7) the main spring without force or adjusting screw (screw) adjustment doesn't fit, make a case between tile much Zhang, a case of a little.

(8)卷揚機制動電磁鐵牽引桿的上下連接極為剛性連執(zhí)牽引桿運動阻力太大，致使電磁鐵產(chǎn)生吸不起來或嘆。

(8) the windlass brake electromagnet traction rod up and down connection is very rigid. The traction rod motion resistance is too large, resulting in electromagnet suction is not up or sigh.
