Detailed Description
The present invention will be described in detail with reference to the accompanying drawings and specific embodiments.
The utility model provides a belt supporting tool for replacing carrier rollers, as shown in figures 1 and 2, comprising a fixed table 1, wherein a fixed clamping jaw 12 is arranged below the bottom of the fixed table 1, an oil tank 2 is arranged on the fixed table 1, a plunger cylinder 3 with an opening at the top end and extending upwards out of the oil tank 2 is arranged in the oil tank 2, a plunger 4 is arranged in the plunger cylinder 3 in a matching way, and a supporting rod 5 positioned above the plunger cylinder 3 is arranged at the top end of the plunger 4; one side of oil tank 2 is provided with pneumatic cylinder 6 on fixed station 1, pneumatic cylinder 6 fit in is provided with the hydraulic oil pole 10 that one end stretches out outward, hydraulic oil pole 10 is located the outer one end of pneumatic cylinder 6 and is connected with operating handle 11, the oil inlet and the oil-out of pneumatic cylinder 6 all are provided with one-way check valve 9, the oil inlet and the oil-out of pneumatic cylinder 6 communicate with oil tank 2 and plunger cylinder 3 through oil circuit pipeline respectively, oil drain hole 7 has still been seted up to plunger cylinder 3's bottom, be provided with the sealing plug 8 that one end stretches out outside oil tank 2 in the oil drain hole 7, the position that sealing plug 8 stretches out oil tank 2 rather than threaded connection.
The plunger 4 comprises a plunger barrel 41 and a plunger rod 42 coaxially connected in the plunger barrel by threads, the plunger cylinder 3 is in sliding fit with the plunger barrel 41, and the support rod 5 is horizontally fixed at the top end of the plunger rod 42. The support rod 5 comprises a support barrel 51 fixed at the top end of the plunger rod 42, and a width adjusting screw rod 52 is coaxially and threadedly connected in the support barrel 51.
When the device is used, the fixed jaw 12 is arranged above a support frame of a belt conveyor carrier roller, the operating handle 11 is pulled in a reciprocating mode, and the hydraulic cylinder 6 is under the action of external force, based on the Pascal law, namely the pressure intensity of each part of liquid is consistent, in a balanced system, the pressure exerted on a smaller piston is smaller, and the pressure exerted on a larger piston is larger, so that the liquid can be kept static, different pressures on different ends can be obtained through the transmission of the liquid, and the purpose of conversion can be achieved. In the process, hydraulic oil in the oil tank 2 enters the hydraulic cylinder 6 through an oil inlet with the one-way check valve 9, then enters the plunger cylinder 3 through an oil outlet with the one-way check valve 9 and lifts the plunger 4 and the supporting rod 5, the lifting height of the supporting rod 5 can be increased by adjusting the position of the plunger rod 42 in the plunger cylinder 41, and the plunger 4 runs upwards after obtaining a large lifting force, so that a belt is driven to move upwards together with the plunger 4. After the belt is jacked up, an operator can replace the carrier roller, after the carrier roller is replaced, the carrier roller is rotated to open the sealing plug 8, so that hydraulic oil in the plunger cylinder 3 flows back to the oil tank 2 through the oil drain hole 7, the oil pressure in the plunger cylinder 3 is reduced, and the plunger 4 falls.
