摘  要

JHB—8型回柱絞車是一種有效的礦山輔助運(yùn)搬設(shè)備。該型絞車主要應(yīng)用于回柱放頂之用，同時(shí)也可用于上山、下山、平巷等綜采工作面設(shè)備的搬遷，比如液壓支架、溜槽等。此外，拉緊皮帶機(jī)機(jī)頭、運(yùn)料、調(diào)度車輛等工作都可以用這種絞車來完成。在港口、碼頭、建筑工地、工廠企業(yè)，這種絞車也可以發(fā)揮作用。
JHB—8型回柱絞車的傳動(dòng)系統(tǒng)采用兩級(jí)傳動(dòng)，包括蝸輪蝸桿齒輪傳動(dòng)、圓柱齒輪傳動(dòng)，在設(shè)計(jì)過程中采用承載能力大的圓弧蝸輪蝸桿；而且采用了開式齒輪傳動(dòng)，大大簡(jiǎn)化了機(jī)械部分的傳動(dòng)系統(tǒng)，便于安裝和拆卸，結(jié)構(gòu)布置緊湊、合理。
在設(shè)計(jì)過程采用錐面制動(dòng)端蓋實(shí)現(xiàn)了工作狀態(tài)和制動(dòng)狀態(tài)的互鎖。絞車起動(dòng)時(shí)動(dòng)載小，鋼絲繩受到的沖擊小。只需輕輕點(diǎn)動(dòng)電機(jī)控制按鈕，就可起動(dòng)電機(jī)，然后操作制動(dòng)的手柄，便可實(shí)現(xiàn)絞車的動(dòng)作。
設(shè)計(jì)中為使回柱絞車具有良好的防爆性能采用了防爆電動(dòng)機(jī)以及防爆磁力啟動(dòng)器和防爆按鈕開關(guān)。該絞車適用條件強(qiáng)、使用壽命長(zhǎng)。該絞車結(jié)構(gòu)緊湊，外形尺寸�。唤Y(jié)構(gòu)為近似對(duì)稱布置，外形美觀，成長(zhǎng)條形，底座呈雪橇狀；絞車重心低，底座剛性好，可安裝地錨，運(yùn)轉(zhuǎn)平穩(wěn)，安全可靠，安裝方便。

ABSTRACT

JHB—8 to prop pulling winch is an effective mine auxiliary equipment shipped to move. This type of winch mainly used to top-of-use, but also can be used to uphill, downhill, Pingxiang fully mechanized coal face, such as the relocation of equipment, such as hydraulic support, the chute, and so on. In addition, the belt-tighten the nose, and transport material, scheduling and other work vehicles can be used to complete the winch. At ports, terminals, construction sites, factories and enterprises, the winch can also play a role.
JHB—8 to prop pulling winch—drive system using two transmission, including worm worm gear drive, cylindrical gear transmission, in the process of designing a large carrying capacity of the arc Worm Gear, and adopted the open-gear transmission, greatly simplifies the Mechanical part of the drive system, easy to install and demolition, structural layout compact and reasonable.
In the design process using cone brake cover state and work to achieve a state of interlocking brake. Starting at the winch dynamic small, the impact on the rope. Just gently move the motor control button, we can start the electrical and operation of the brake handle, can be realized winch action.
Design for the prop pulling winch has a good performance by the explosion-proof electrical explosion-proof and explosion-proof magnetic starter button switch. The winch conditions apply strong and long life. The winch compact structure, shape, small size, structure similar to symmetrical layout, aesthetic appearance, growth Strip, a sled-shaped base; winch low center of gravity, rigid base, and can be installed to anchor, a smooth operation, safety and reliability, ease of installation.
