Description

A roller bed used for skid maintenance

technical field

The utility model belongs to the field of equipment maintenance, in particular to a roller bed used for skid maintenance. the

Background technique

At present, skids are used as supporting transfer equipment when many products are produced on the assembly line, especially in the automobile manufacturing industry. Then the skid is difficult to avoid being transferred or repaired during the production process. During the maintenance of the skid, the maintenance personnel need to transfer the skid to the maintenance area. In the prior art, the skid is used for maintenance work It is a flat roller bed. Since the slide bar of the skid needs to be corrected by means of the flat plane of the roller bed, the existing flat roller bed does not have rollers, and the skid is completely forced by manpower to push the skid into and out of the flat roller bed, which is labor-intensive. the

Contents of the invention

The utility model provides a roller bed for skid maintenance, which has the advantages of simple operation, time-saving and labor-saving, and the ability to load the skid into the roller bed by a single person. the

In order to achieve the above purpose, the technical solution adopted by the utility model is: a roller bed used for skid maintenance, including a platform and supporting feet, the platform is a frame, and the two frames of the frame are provided with There are several pairs of parallel and opposite grooves, rollers are arranged in the grooves, and the opposite pair of rollers are connected by rollers, and the rollers are fixed on the jacking device. the

The jacking device can control the rollers to rise or fall in the groove. When the skid needs to be loaded, the jacking device lifts the rollers out of the groove, and the skid can be easily pushed into the platform by a single person under the rolling action of the rollers. After the skid is in place, the scissor-type hydraulic jacking device, the rollers descend into the groove, and the plane of the platform can be used to correct the slide bar of the skid and other maintenance items. After the overhaul is completed, the lifting device lifts the rollers, the skid is separated from the platform plane, and the skid can be pushed out of the roller bed. the

The jacking device includes a base, a movable single-fork bracket arranged on the base, a lifting plate arranged on the movable single-fork bracket, and the lifting plate is connected to the base with a hydraulic device, and the rollers are fixed on the lifting plate in parallel superior. the

The hydraulic device pushes the lifting plate up, and at the same time, the expansion of the single-fork bracket can control the height of the lifting plate, and the lifting plate is connected with the roller to control the roller to protrude or sink into the groove. the

The hydraulic device includes a fuel tank, a hydraulic pump, a hydraulic cylinder, a throttle valve, and an overflow valve. The fuel tank communicates with the hydraulic pump, the hydraulic pump communicates with the hydraulic cylinder through the throttle valve, and the overflow valve is arranged between the fuel tank and the throttle. Between the flow valves, the overflow valve communicates with the oil tank; the hydraulic cylinder includes a cylinder body and a piston rod sleeved in the cylinder body, the cylinder body is connected to the base, and the piston rod is connected to the lifting plate. the

The throttle valve can control the speed of hydraulic oil flowing into the hydraulic cylinder, and then control the lifting speed of the piston rod of the hydraulic cylinder to push the lifting plate. The overflow valve installed on the hydraulic cylinder can control the pressure of the hydraulic cylinder. When the pressure exceeds the predetermined pressure, the overflow The valve opens and excess hydraulic oil returns to the tank, allowing a constant lift force on the skid as it is pushed into the roll bed. the

The number of the grooves is preferably 4 pairs, so the number of the rollers is correspondingly 4 pairs, so that the stability during the skid process is guaranteed while taking into account the economy of the entire roller bed. the

The utility model has the advantages of simple operation, time saving and labor saving, and a single person can easily push the skid into the roller bed, which reduces the labor intensity of the operators and improves the production efficiency. the

Description of drawings

Fig. 1 is a structural schematic diagram of the state in which the rollers protrude from the grooves in the roller bed used for skid maintenance of the present invention. the

Fig. 2 is a structural schematic diagram of the state that the rollers in the roller bed used for skid maintenance and maintenance of the utility model are submerged in grooves. the

Detailed ways

The utility model is described in detail below in conjunction with the accompanying drawings. the

As shown in Figures 1 and 2, the platform of the roller bed used for skid maintenance is a frame platform 1, which is fixed horizontally by eight support feet 2, and the two frames of the frame platform 1 are evenly equipped with four parallel and opposite sides. For the groove 101, the inner arm of the frame platform 1 is provided with a roller groove 102 vertically connected with the groove 101, and the two ends of the roller 31 extend horizontally from the roller groove 102 into the two opposite grooves 101 , the roller 3 is installed on both ends of the roller 31 in the groove 101 . The roller 31 is fixed on the lifting plate 43 of the lifting device 4 in the frame platform 1, the lifting plate 43 is fixed on the single fork support 42, the bottom of the single fork support 42 is connected with the base 41, and the base 41 is provided with an oil tank 441, Hydraulic pump 442, hydraulic cylinder 443, throttle valve 444, overflow valve 445, oil tank 441 communicates with hydraulic pump 442 with high pressure oil pipe, hydraulic pump 442 communicates with hydraulic cylinder 43 with high pressure oil pipe through throttle valve 444, overflow valve 445 Set on the hydraulic cylinder 443, the overflow valve 445 communicates with the oil tank 441 through a low-pressure oil pipe. the

The cylinder body of the hydraulic cylinder 443 is connected to the base (41), and the piston rod is connected to the lifting plate (43) to control the height of the lifting plate 43, thereby realizing that the roller 3 stretches out or sinks into the groove 101. When it is necessary to load the skid, The roller 31 on the lifting plate 43 rises in the roller groove 102, the roller 3 protrudes from the groove 101, and the skid can be easily pushed into the frame platform 1 by a single person under the rolling action of the roller 3, and the skid is in place Finally, the roller 3 descends into the groove 101, and the plane of the frame platform 1 can be used to correct the slide bar of the skid and complete other maintenance items. the

The throttle valve 444 can control the speed at which the hydraulic oil flows into the hydraulic cylinder 443, and then control the lifting speed of the lifting plate 43. The overflow valve 445 arranged on the hydraulic cylinder 443 can control the pressure of the hydraulic cylinder 443. When the pressure exceeds a predetermined pressure, the overflow The valve 445 is opened, and excess hydraulic oil flows back into the oil tank 441, so that the lifting force received by the skid during pushing into the roller bed is constant. the
