Embodiment Construction

[0013] Such as figure 1 and figure 2 As shown, the hydraulic chain tightening device of the side double chain chain plate machine provided by the present invention is characterized in that it includes a set of scrapers 2, and the section of the scrapers 2 is an I-shaped structure with steps. The two ends of the two chains 6 are connected by connecting rings 7, and each connecting ring 7 connects two chains 6 together. One block 1 is clamped on two of the scrapers 2 respectively, and two scrapers 2 are spaced between the two blocks 1 . A hydraulic pump 3 is connected between the connecting seats 1d of the two blocks 1 through a connecting pin, the hydraulic pump 3 is connected to the hydraulic lock 4 through the hose 8, and the hydraulic lock 4 is connected to the head and tail valve 5 through the hose 8.

[0014] combine Figure 4 As shown, the front end of the connecting ring 7 is a split ring 7a matched with the chain 6, a symmetrical connecting plate 7b is provided at t...

Abstract

The invention relates to a hydraulic chain tightening device for a mining edge double chain plate machine, which is characterized by comprising a group of scraping plates (2), wherein cross sections of the scraping plates (2) are in stepped I-shaped structures; the two ends of each scraping plate (2) are connected with chains (6) by connecting rings (7); two of the scraping plates (2) are connected with clamping blocks (1) in an upper matching manner respectively; at least one scraping plate (2) is arranged between the two clamping blocks (1) at an interval; a hydraulic pump (3) is articulated between the two clamping blocks (1), and connected with a hydraulic lock (4) by a hose (8); and the hydraulic lock (4) is connected with a head-tail valve (5) by the hose (8). The device has the advantages that chain scission or combination working of the chain plate machine is accomplished by long-distance fluid feed and the extension of the hydraulic pump, so that a process of the device is concise and efficient; the working safety is improved; the labor difficulty and the risk are reduced; and the operation safety of staff is guaranteed.

Description

technical field [0001] The invention relates to a coal mining machine, in particular to a hydraulic chain tightening device for a mine side double chain chain plate machine. Background technique [0002] At present, it is very common to use side double-chain chain conveyors to transport coal and gangue in the underground mining of coal mines in my country. In the process of using the chain conveyor, due to the needs of the work, the chain breaking or chain closing process of the chain conveyor is very frequent, and the process of chain breaking or chain closing must be carried out under the condition of the chain. The traditional method of breaking the chain and closing the chain is to lock one end of the chain on the chain presser on the head shell, then reverse the ignition, hold the connecting ring by hand and take it off or hang it on. This method relies on the chain tension state maintained by the momentary drive torque of the motor to operate by hand. If the movement ...
