Description

Technical Field

[0001] The utility model relates to the assembly of a roller, in particular to a roller rubber ring installation device, belonging to the technical field of machinery. Background Art

[0002] In coking production equipment, belt conveyors are used in many places. These belt conveyors need rollers of different lengths according to different models. The working environment of coke conveyor belts is relatively harsh, and the requirements for rollers to be resistant to high temperature and corrosion are still very high. Therefore, coking plants generally install teams specializing in assembling rollers. In the assembly of rollers, one of the main contents is to put rubber rings on the roller shafts. In coking enterprises, there are rollers of different lengths. For common 1.2m and 133mm diameter rollers, dozens of rubber rings need to be installed on the roller shafts, and the rubber rings and the roller shafts are tightly matched. At present, The method of installing rubber rings on the roller shaft is described in detail in the background technology of Chinese patent CN112192509B. The mechanical method requires large investment and is inflexible, and the manual method is labor-intensive. The patent also provides a buffer roller rubber ring pressing device and a method of using it, but this method requires replacing the support block according to different types of rollers. For larger rollers, such as the long rollers used in the coking plant, which weigh more than 30kg, it is very inconvenient to load and unload materials, and the equipment occupies a large area. Due to the large number of rubber rings and the tight fit between the rubber rings and the roller shafts, manual labor is still relatively laborious without mechanical assistance. Summary of the invention

[0003] The utility model aims to provide a rubber roller with a rubber ring device.

[0004] To achieve the purpose of the utility model, the following technical scheme is adopted: a roller rubber ring device, comprising a base, a guide column fixedly installed in the vertical direction on the base, a guide sleeve is provided on the guide column for sliding sleeve, a cross beam is fixedly connected to the guide sleeve, a cylindrical pressure head is fixedly provided on the end of the cross beam, the movable end of the electric hydraulic push rod is hinged on the cross beam, the electric hydraulic push rod is hinged on the hinge seat, the hinge seat is fixedly connected to the base, a limit rod is provided under the cross beam, the limit rod is fixedly connected to the bottom plate, the front end of the bottom plate is hinged to the base through a hinge axis in the horizontal left and right directions, and when the limit rod is in the vertical direction, the bottom plate is supported on the base and the limit rod is located below the cylindrical pressure head.

[0005] Furthermore, a movable limit plate is fixedly connected to the hinge seat, and a fixed limit plate is fixedly connected to the base. When the hinge shaft rotates to a set angle, the fixed limit plate interferes with the movable limit plate.

[0006] Furthermore, the roller rubber ring device also includes a sleeve member, which is hollow and can be sleeved on the limit rod. The upper end of the sleeve member has a radial flange.

[0007] Furthermore, a support frame is fixedly connected to the base, the upper end of the support frame is fixedly connected to the guide column, and the lower end is fixedly connected to the base, and a triangle is formed between the support frame, the guide column and the base.

[0008] The positive and beneficial technical effects of the utility model are: the device has a simple structure, is convenient for loading and unloading, and is easy to switch between rollers of different lengths. BRIEF DESCRIPTION OF THE DRAWINGS

[0014] In order to more fully explain the implementation of the utility model, implementation examples of the utility model are provided. These implementation examples are only for the purpose of illustrating the utility model and do not limit the scope of the utility model.

[0015] The present invention is further explained in detail in conjunction with the accompanying drawings, in which the marks are: 1: base; 2: guide column; 3: guide sleeve; 4: crossbeam; 5: hydraulic electric push rod; 6: articulated seat; 7: limit rod; 8: bottom plate; 9: articulated shaft; 10: support frame; 11: movable limit plate; 12: fixed limit plate; 13: sleeve member; 14: flange; 15: roller shaft; 16: rubber ring.

[0016] As shown in the accompanying drawings, a roller rubber ring installation device includes a base 1, a guide column 2 fixedly installed in the vertical direction on the base, a support frame 10 fixedly connected to the base, the upper end of the support frame is fixedly connected to the guide column, and the lower end is fixedly connected to the base, and a triangle is formed between the support frame, the guide column and the base, so that the triangular structure is very stable when in use.

[0017] A guide sleeve 3 is provided on the guide column 2 for sliding sleeve, a cross beam 4 is fixedly connected to the guide sleeve 3, a cylindrical pressure head 17 is fixedly provided at the end of the cross beam 4, a movable end of a hydraulic electric push rod 6 is hinged on the cross beam 4, the hydraulic electric push rod is hinged on the hinge seat 6, the hinge seat 6 is fixedly connected to the base 1, a limit rod 7 is provided below the cross beam 4, the limit rod 7 is fixedly connected to the bottom plate 8, the front end of the bottom plate 8 is hinged to the base 1 through a hinge shaft 9 in the horizontal left and right directions, a movable limit plate 11 is fixedly connected to the hinge seat, a fixed limit plate 12 is fixedly connected to the base, when the hinge shaft rotates to a set angle, the fixed limit plate interferes with the movable limit plate, in this embodiment, the upper end surface of the base is a horizontal plane, when the bottom plate is in a horizontal state, the movable limit plate faces upward, the fixed limit plate is fixedly connected to the bottom plate, the hinge shaft rotates no more than 90 degrees and the movable limit plate interferes with the fixed limit plate, at this time the limit rod is close to a horizontal state, which is convenient for loading and unloading the roller shaft and the roller. When the limiting rod 7 is in the vertical direction, the bottom plate is supported on the base, and the limiting rod is located below the cylindrical pressure head.

[0018] The roller rubber ring device also includes a sleeve 4, the length of which is smaller than the limit rod, and the sleeve is hollow and can be sleeved on the limit rod. The sleeve has a radial flange 15 near the upper end. The sleeve is used to assemble the short roller. When assembling the short roller, the sleeve is sleeved on the limit rod. After the roller shaft is sleeved on the limit rod, the lower end is limited by the flange (such as Figure 5 as shown) for easy assembly.

[0019] When the device is used to install the rubber ring on the roller shaft, first, the limit rod is flipped forward, and the movable limit plate is limited by the fixed limit plate. At this time, the limit rod is in a nearly horizontal upward inclined state, and then the center hole of the roller shaft is inserted into the limit rod, and then the roller shaft is flipped to drive the limit rod to flip to a vertical state. The bottom plate is supported on the base, and then the rubber ring is manually installed on the roller. After installing about 5 rubber rings, the hydraulic electric push rod is started downward, and the cylindrical pressure head presses the installed rubber ring down along the roller shaft, the hydraulic electric push rod is raised, and the rubber ring is continued to be installed. Repeat the above steps. After all the rubber rings are installed, the limit rod is flipped forward and the roller can be taken out.
