Description

Technical Field

[0001] The utility model relates to the field of mechanical equipment technology, in particular to a prying trolley push plate oil cylinder piston rod guard plate. Background Art

[0002] In mines and similar operating environments, skidding trolleys are crucial equipment for cleaning the jobsite, particularly removing debris such as scattered slag, waste rock, and other debris. This type of equipment typically utilizes a hydraulic system to drive its working mechanism, with the push plate cylinder, a crucial component, responsible for pushing the push plate to clear the material. However, in actual use, due to the limited width of the push plate, when encountering large volumes of slag or waste rock, these objects can easily slip off the edge of the push plate and directly impact the piston rod of the push plate cylinder, damaging the piston rod. Scratches or dents on the piston rod surface not only compromise the cylinder's internal seal, leading to oil leakage, but also accelerate aging and wear of internal components, shortening the cylinder's service life.

[0003] Furthermore, the working environment of a mining trolley is often harsh, with large amounts of dust, gravel, and other impurities present. These external factors can also contaminate the hydraulic cylinder, exacerbating its damage. A cylinder failure not only requires significant time and cost to repair or replace, but also severely impacts the trolley's operating efficiency, resulting in unnecessary financial losses for mining operations.

DETAILED DESCRIPTION

[0022] like Figure 1 As shown, a prying trolley push plate oil cylinder piston rod guard plate includes a support guard plate 1, a movable support point 2 and a self-locking hinge 3. The cylinder barrel 5 is connected to the trolley push plate 6 through the cylinder piston rod 4. The support guard plate 1 is arranged above the cylinder barrel 5. The support guard plate 1 is movably hinged to the trolley push plate 6 through the self-locking hinge 3. The end of the support guard plate 1 is provided with a movable support point 2 and abuts against the cylinder barrel 5.

[0023] During use of the device, by arranging a support guard plate 1 above the cylinder barrel 5 and the cylinder piston rod 4, it can effectively prevent falling rocks from directly hitting the cylinder piston rod 4 during the operation of the prying trolley, reduce unnecessary consumption, and reduce maintenance frequency and maintenance costs.

[0024] The preferred solution is Figure 2 As shown, the support guard plate 1 includes a sleeve plate 101 and a telescopic plate 102. The telescopic plate 102 is inserted into the sleeve plate 101 and is limited and telescopic along the sleeve plate 101. The end of the telescopic plate 102 is provided with a movable support point 2. The end of the sleeve plate 101 is movably hinged to the trolley push plate 6. The upper end surface of the sleeve plate 101 is provided with a threaded connection port 103. The fastening bolt 104 is threadedly connected to the threaded connection port 103 and locks the extension distance of the telescopic plate 102.

[0025] Before using the device, the telescopic plate 102 is pulled out according to the actual length of the cylinder barrel 5 and the cylinder piston rod 4 so that it can completely cover the cylinder piston rod 4. When the position of the telescopic plate 102 is adjusted into place, the fastening bolt 104 is tightened downward and made to abut against the telescopic plate 102, thereby fixing the extension distance of the telescopic plate 102.

[0026] The preferred solution is Figure 3As shown, the movable support point 2 includes a support plate 201, a rubber ball 202, a rotating shaft 203 and a threaded connector 204; the support plate 201 is fixedly connected to the inner wall of the support guard plate 1, a rubber ball 202 is provided inside the support plate 201 and is in rolling connection with the outer wall of the cylinder 5, the rotating shaft 203 is inserted at the axis of the rubber ball 202, and the rubber ball 202 rotates freely around the axis of the rotating shaft 203, and the threaded connector 204 passes through both sides of the support plate 201 and is threadedly connected to the end of the rotating shaft 203;

[0027] Since the rubber ball 202 is in rolling connection with the outer wall of the oil cylinder 5 , when the oil cylinder piston rod 4 drives the trolley push plate 6 to extend and retract, the end of the support guard plate 1 and the oil cylinder 5 maintain relative sliding, which will not affect the normal operation of the oil cylinder 5 .

[0028] The preferred solution is Figure 4 As shown, the self-locking hinge 3 includes a first connecting plate 301 and a second connecting plate 302. The first connecting plate 301 is detachably connected to the trolley push plate 6, and the second connecting plate 302 is detachably connected to the support guard plate 1. The sides of the first connecting plate 301 and the second connecting plate 302 are provided with connecting sleeves 303. The self-locking shaft 304 passes through the connecting sleeve 303 to movably connect the first connecting plate 301 and the second connecting plate 302.

[0029] The front half of the self-locking shaft 304 and the center hole of the connecting sleeve 303 are corresponding polygonal structures, and the rear half of the self-locking shaft 304 is a cylindrical structure. A handle 305 is provided at one end of the self-locking shaft 304, and a baffle 306 is provided at the other end of the self-locking shaft 304;

[0030] During use, when the opening and closing angles of the first connecting plate 301 and the second connecting plate 302 need to be adjusted, the self-locking shaft 304 is slid to the right so that the cylindrical section of the self-locking shaft 304 passes through the connecting sleeve 303. At this time, the first connecting plate 301 and the second connecting plate 302 can rotate freely around the axis of the self-locking shaft 304.

[0031] When the opening and closing angles of the first connecting plate 301 and the second connecting plate 302 are adjusted to the desired position, the self-locking shaft 304 is slid to the left so that the polygonal structure of the front half thereof is inserted into the polygonal hole corresponding to the connecting sleeve 303. At this time, the first connecting plate 301 and the second connecting plate 302 are locked and fixed by the self-locking shaft 304.

[0032] A handle is provided at the end of the self-locking shaft 304 to facilitate pulling it out, and a baffle 306 is provided at the other end of the self-locking shaft 304 to prevent it from falling out of the connecting sleeve 303.
