小型混凝土攪拌機的輪胎常常接觸地面,而且經常受到很大的壓力,因此對輪胎有著很嚴格的要求,而且攪拌機在使用一段時間之后一定要及時替換輪胎。替換輪胎有必要通過的一步是拆開輪胎。那么我們應該如何拆開呢?
The tires of small concrete mixer often contact with the ground and are often subject to great pressure, so there are very strict requirements for tires, and the mixer must replace the tires in time after using for a period of time. One of the necessary steps to replace a tire is to take the tire apart. So how do we take it apart?
一、拆卸輪胎時,應在清潔、平整、枯燥、堅硬且無油污的空中上停止,以避免沙土、雜物等落到外胎內壁或粘附于內胎外表損壞內胎,并避免油污粘附于輪胎上腐蝕輪胎。
1、 When removing the tire, it should be stopped in a clean, flat, dry, hard and oil free air to avoid sand, debris, etc. falling on the inner wall of the outer tube or adhering to the outer surface of the inner tube, damaging the inner tube, and preventing the oil stain from adhering to the tire and corroding the tire.
二、拆卸小型混凝土攪拌機輪胎應由有實踐經歷的人員操作或指導,切不可亂敲亂打,以免使輪圈產生銳邊、凹痕、龜裂等缺陷,并要堅持輪圈的清潔,避免銹蝕損壞。
2、 The removal of small concrete mixer tires should be operated or guided by experienced personnel. It is not allowed to knock and hit randomly, so as to avoid sharp edges, dents, cracks and other defects on the wheel rim. The wheel rim should be kept clean to avoid corrosion damage.
三、只能運用專用工具和撬棒停止拆裝,停止運用螺絲刀之類的鋒利工具。
3、 Only use special tools and crowbars to stop disassembly and assembly, and stop using sharp tools such as screwdrivers.
四、拆卸辦法。放掉輪胎中的空氣,應用氣門帽將氣門芯擰出,打下氣門嘴固定螺母,用雙腳踩踏或用錘子重擊外胎側面,使輪胎的胎圈脫離輪圈邊緣進入輪輞中部凹槽內,將氣門嘴推進輪圈內。在氣門嘴左近將撬棒插入胎緣輪輞之間,將胎緣撬起,同時在撬胎棒的對面用力緊縮外胎胎壁,使外胎盡量移向輪輞中部凹槽內,行將撬出的部位盡量放松。
4、 Disassembly method. Let off the air in the tire, screw out the valve core with the valve cap, screw down the valve fixing nut, step on the side of the outer tire with both feet or hit the side of the outer tire with a hammer to make the tire bead separate from the rim edge and enter into the groove in the middle of the rim, and push the valve into the rim. Insert the crowbar between the bead rims at the left side of the valve, pry up the tire bead, and at the same time, tighten the tire wall of the outer tire on the opposite side of the tire prying bar, so that the outer tire moves to the groove in the middle of the rim as far as possible, and the part to be pried out shall be relaxed as far as possible.
五、假如小型混凝土攪拌機輪胎運用日久,外胎銹死在輞圈內而不容易取下時,能夠將輪胎平放在潔凈的空中上,用撬棒在胎口與輞圈之間撬開一定間隙,在輞圈與外胎的分離部倒些肥皂水或清水,并用鐵錘沿l輪圈外側稍加錘擊,使水在振動的過程中從縫隙處滲入生銹面,待浸透后,外胎便容易拆下來。
5、 If the tire of small concrete mixer is used for a long time and the tire rust is dead in the rim and it is not easy to take it off, the tire can be placed flat in the clean air, pry a certain gap between the tire bead and the rim with a crowbar, pour some soapy water or water into the separation part of the rim and the tire, and hammer slightly along the outer side of the L wheel rim with a hammer, so that the water can penetrate into the gap during vibration The rusty surface will be easily removed after soaking.
小型混凝土攪拌機輪胎連接著很多配件,需要在拆卸的過程中不僅要注意方法,而且還要注意拆卸的過程。在整個拆卸過程中記得將拆下來的零件統一放好。
The tire of small concrete mixer is connected with many accessories. It is necessary to pay attention not only to the method but also to the disassembly process. In the whole process of disassembly, remember to put the removed parts in a unified way.
