手拉葫芦维护方法

1.使用完毕应将葫芦清理干净并涂上防锈油脂，存放在干燥地方，防止手拉葫芦受潮生锈和腐蚀。

2.维护和检修应由较熟悉葫芦机构者进行，用煤油清洗葫芦机件，在齿轮和轴承部分，加黄油润滑，防止不懂本机性能原理者随意拆装。

3.葫芦经过清洗维修，应进行空载试验，确认工作正常，制动可靠时，才能交付使用。

4.制动器的摩擦表面必须保持干净。制动器部分应经常检查，防止制动失灵，发生重物自坠现象。

5.手拉葫芦的起重链轮左右轴承的滚柱，可用黄油粘附在已压装于起重链轮轴颈的轴承内圈上，再装入墙板的轴承外圈内。

6.手拉葫芦在安装制动装置部分时，注意棘轮齿槽与棘爪爪部啮合良好，弹簧对棘爪的控制应灵活可靠，装上手链轮后，顺时针旋转手链轮，就将棘轮、摩擦片压紧在制动器座上，逆时针旋转手链轮，棘轮与摩擦片间应留有空隙。

7.为了维护和拆卸方便，手链条其中一节系开口链(不允许焊死)。

8.在加油和使用手拉葫芦过程中，制动装置的摩擦面必须保持干净，并经常检查制动性有无，防止制动失灵引起重物自坠。

Maintenance Method 1. After use, the gourd should be cleaned and coated with antirust grease, stored in a dry place to prevent the hand gourd damp rust and corrosion. 2. Maintenance and repair should be carried out by those who are familiar with the machine. Kerosene should be used to clean the machine parts, and butter should be added to lubricate the gears and bearings. 3. After cleaning and maintenance of the gourd, should be carried out no-load test to confirm that the work is normal, reliable braking, to be delivered to use. Four. The friction surface of the brake must be kept clean. The brake part should be checked frequently to prevent brake failure and heavy object falling. 5. The Rollers of the left and right bearings of the lifting sprocket of the hand chain hoist can be adhered with butter to the bearing inner ring which has been pressed onto the bearing journal of the lifting sprocket, and then loaded into the bearing outer ring of the wall panel. 6. When installing the brake device of the hand chain hoist, pay attention to the good engagement between the ratchet tooth groove and the pawl part. The spring should be flexible and reliable to the control of the pawl. After installing the hand sprocket, turn the hand sprocket clockwise, on the ratchet, friction plate pressed in the brake seat, counter-clockwise rotation hand sprocket, Ratchet and friction plate should be left between the gap. Seven. For easy maintenance and disassembly, one section of the bracelet is an open chain (no welding is allowed) . 8. In the process of fueling and using the hand hoist, the friction surface of the brake must be kept clean, and always check the brake, to prevent brake failure caused by heavy weight self-fall.
