Abstract
The utility model provides a crane clamp transmission case, which adopts a split combined structure, wherein a left case body and a right case body are fixed on a clamp body, and a front case body is connected on the left case body and the right case body through bolts; a bottom plate is laid at the bottom of a clamp body web plate, and an asbestos heat insulation layer is filled between the web plate and the bottom plate; a middle heat insulation plate is arranged between the motor box and the right box body, and two sides of the middle heat insulation plate are supported on the clamp body web plate and are fixed through a stop arranged at the front part. The utility model discloses convenient and fast and weight reduction are dismantled to the transmission case, can greatly use manpower sparingly and time, guarantee to overhaul operation personnel safety, have solved the problem that pincers body internal plant temperature is too high, have prolonged the life of each part, have improved the crane operation rate, can effectively reduce the spare parts cost.
Description
Technical Field
The utility model belongs to handling equipment field especially relates to a handling for slab crane clamp transmission case.
Background
The slab clamp crane is mainly used for clamping slab operation through the clamp lifting appliance, and the clamp lifting appliance clamp body controls the clamp to open and close through the internal transmission mechanism. The bottom of the box body of the pliers body is only made of a layer of steel plate with the thickness of 3mm, the temperature of the clamped plate blank is more than 800 ℃, and the distance from the clamped plate blank to the web plate of the pliers body is only 1.2 m, so that the internal temperature of the pliers body is overhigh, the performance of a lubricating system of each part is relatively reduced, and each part is frequently damaged. In addition, when the internal transmission mechanism of the clamp body is in fault, the box body needs to be disassembled every time, the box body is designed into a sectional type structure with 2 sections, the specification of each section is 1470 x 800 x 400mm, the weight is about 70kg, the box body is fixed by 7M 12 bolts, the bolts need to be disassembled during disassembly, 4 persons are required to lift up simultaneously, time and labor are wasted, the overhaul time of equipment is prolonged, the safety cannot be fully guaranteed, and the normal operation of a crane is influenced.
Disclosure of Invention
The utility model provides a can solve and clamp the transmission case and dismantle hard problem consuming time, shorten the maintenance activity duration, guarantee maintenance operation personnel safety improves the crane clamp transmission case of crane operation rate.
Therefore, the utility model discloses the technical solution who takes does:
a crane clamp transmission case comprises a left case body, a front case body, a right case body, a motor case, an asbestos heat-insulating layer, a middle heat-insulating plate and a stop; the transmission case adopts a split combined structure, the left case body and the right case body are horizontally fixed on the clamp body, and the front case body is connected to the left case body and the right case body through bolts; an angle steel frame is welded at the bottom of a clamp body web plate, a bottom plate is laid at the bottom of the angle steel frame, and an asbestos heat insulation layer is filled between the web plate and the bottom plate; a middle heat insulation plate is arranged at a coupling part between the motor box and the right box body, and two sides of the middle heat insulation plate are loaded on the clamp body web plate and are fixed through a stop arranged at the front part.
The utility model has the advantages that:
the utility model discloses the transmission case need not wholly dismantle the box, only need dismantle the front box can, very convenient and weight reduction can greatly use manpower sparingly and time, guarantee maintenance operation personnel safety; because the heat insulation layer is additionally arranged on the box body, the problem of overhigh temperature of equipment inside the clamp body caused by design defects is solved, the service life of each part is prolonged, the operation rate of the crane is improved, and the cost of spare parts can be effectively reduced.
Drawings
FIG. 1 is a crane clamp gearbox assembly view;
FIG. 2 is a schematic view of a crane clamp gearbox configuration;
fig. 3 is a left side schematic view of a crane tong gear box.
In the figure: the heat insulation box comprises a left box body 1, a front box body 2, a right box body 3, a motor box 4, a middle heat insulation plate 5, a bolt 6, an angle steel stopper 7, a web plate 8, an asbestos heat insulation layer 9, a bottom plate 10 and a clamp body 11.
Detailed Description
The utility model discloses crane clamp transmission case includes left box 1, preceding box 2, right box 3, motor case 4, middle heat insulating board 5, angle steel backstop 7 and asbestos insulating layer 9. The transmission case adopts a split combined structure, the left case body 1 and the right case body 3 are horizontally fixed on the clamp body 11, and the front case body 2 is connected on the left case body 1 and the right case body 3 through bolts 6. An angle steel frame is welded at the bottom of the clamp body web plate 8, a bottom plate 10 is laid at the bottom of the angle steel frame, and an asbestos heat insulation layer 9 is filled between the web plate 8 and the bottom plate 10. The middle heat insulation plate 5 is arranged at the coupling part between the motor box 4 and the right box body 3, and two sides of the middle heat insulation plate 5 are loaded on the clamp body web plate 8 and fixed through an angle steel backstop 7 arranged at the front part.
The transmission case is connected with the bolts 6 by adopting a split combined structure, and when the transmission case needs to be disassembled, only 1-2 persons need to disassemble the front case body 2, so that the transmission case is very convenient and the weight is reduced. The asbestos heat insulation layer 9 is filled between the web plate 8 and the bottom plate 10, so that the heat insulation effect of the web plate 8 can be enhanced, and the high-temperature phenomenon caused by baking in the clamp body is reduced. The middle heat insulation plate 5 is placed at the position of the coupler between the motor box 4 and the right box body 3, when the tong arm fails or is powered off, the middle heat insulation plate 5 can be lifted upwards and taken out, the operation space of the pipe wrench is reserved, the pipe wrench is used for repeatedly turning the transmission shaft, the tong body 11 can be opened emergently, the middle heat insulation plate 5 is reset after the operation is finished, and the operation is very quick and convenient.
