Drawings
FIG. 1 is a schematic diagram of the structure of the present utility model.
Fig. 2 is an enlarged partial cross-sectional view of the area a in fig. 1.
Marked in the figure as: the device comprises a 1-bottom mounting plate, a 2-side vertical plate, a 3-bottom mounting screw, a 4-upper mounting plate, a 5-upper mounting plate mounting screw, a 6-screw lifter, a 7-screw lifter mounting screw, an 8-special tooling press head, a 9-hand wheel, a 10-head mounting plate, a 41-screw wall hole and an 81-handrail.
Detailed Description
The utility model is further described below with reference to the accompanying drawings.
The manual press structure of the utility model is shown in fig. 1, and comprises a bottom mounting plate 1, an upper mounting plate 4, and a tread braking unit to be disassembled is placed on the bottom mounting plate. The bottom mounting plate 1, connect through the side riser 2 between the upper portion mounting plate 4, install screw lift 6 on the upper portion mounting plate 4, install screw lift 6 and be equipped with hand wheel 9, install screw lift 6 lower extreme and be head mounting plate 10, be connected with special frock pressure head 8 through special frock installation bolt subassembly below head mounting plate 10, special frock installation bolt subassembly includes four bolts.
The upper mounting plates 4 are connected with the side vertical plates 2 through upper mounting plate mounting screws 5, the number of the side vertical plates is two, and the number of the upper mounting plate mounting screws 5 on each side is 3; the bottom mounting plate 1 and the side vertical plates 2 are connected through the bottom mounting screws 3, the number of the side vertical plates is two, and the number of the bottom mounting screws 3 on each side is 3. The frame structure has the advantages of large operation space, clear visual field, convenient part compression and disassembly, simple structure, easy disassembly and assembly, and the plate structure can ensure enough strength and provide enough stability. Because the pressure applied by the press to the tread braking unit to be disassembled is in the vertical direction, the connection mode between the side vertical plate 2 and the bottom mounting plate 1 and the upper mounting plate 4 is just to ensure that the vertical direction can bear enough force, and the screw connection is a mode which is stable and convenient to disassemble. The pin shaft and the pin hole can be connected in a matched mode, the axis of the pin shaft is required to be kept horizontal and vertical to the force application direction of the pressure, and the structure has higher strength and poorer stability.
The center position of the upper mounting plate 4 is provided with a screw through-wall hole 41, so that a screw of the screw lifter 6 can penetrate through the upper mounting plate 4, and the screw can freely move up and down in the press frame. The screw rod lifter 6 is fastened on the upper mounting plate 4 at the periphery of the screw rod wall passing hole 41 through four screw rod lifter mounting screws 7, the screw rod downwards passes through the upper mounting plate, the lowest end is the head mounting plate 10, the special tooling press head 8 is connected below the head mounting plate 10, the special tooling press head 8 is further provided with an armrest 81, the operator can conveniently hold the screw rod lifter, and the stability of the overall structure is maintained by holding the armrest 81 when larger pressure is applied due to the fact that parts of the tread brake operator are irregular.
When the tread braking unit is disassembled, the hand wheel 9 is operated to rotate, so that the screw rod of the screw rod lifter 6 moves up and down, the special tool pressing head 8 is driven to move up and down, parts inside the tread braking unit are pressed and loosened, and the parts can be disassembled and assembled. The press parts are few, the structure is simple, stable and reliable, and all parts of the press are connected through screws, so that the parts of the press can be replaced quickly, and when the total maximum height of the press frame cannot meet the disassembly and installation height of the parts, the height of the upper mounting plate 4 can be adjusted by replacing the two side vertical plates 2, and the disassembly and installation of the parts with different heights can be completed. The replacement operation is very simple, and only the mounting screw connected with the serial number 2 side vertical plate needs to be detached.
The special tooling pressure heads 8 of different parts are connected with the head mounting plate 10 of the screw rod lifter through 4 special tooling mounting bolt assemblies. The parts with corresponding structures can be disassembled and installed by replacing the special tool press head 8. When the special press pressure head needs to be replaced, the replacement can be completed only by disassembling the special tool mounting bolt assembly.
The manual press for overhauling the subway tread braking unit can be applicable to more tread braking units as much as possible, so that the manufacturing cost of the tooling is saved, and the occupation of an overhauling field is reduced. The method can be widely applied to maintenance work of subway vehicles.
