Abstract
The utility model discloses an excavator pump chamber heat insulating board belongs to the excavator field. The key points of the technical scheme are as follows: the heat insulation plate comprises a heat insulation plate body, wherein a mounting opening is formed in the heat insulation plate body, and the heat insulation plate body comprises two heat insulation plate units which can be spliced in a separable mode. The utility model discloses pump chamber heat insulating board is two separable assemblings of thermal-insulated unit board, has promoted assembly efficiency, has reduced manufacturing cost, has increased thermal-insulated effect and leakproofness moreover.
Description
Technical Field
The utility model belongs to an excavator part, specifically speaking especially relates to an excavator pump chamber heat insulating board.
Background
The excavator pump chamber heat insulation plate is a structure for isolating an excavator engine chamber from a hydraulic pump chamber. The engine room mainly has the effects that heat flow of the engine room is led out through the engine hood, and heat exchange between the engine room and the hydraulic pump room is isolated to a certain extent, so that the problem of overheating of the hydraulic pump and accessories of the hydraulic pump is solved. The concrete structure of the prior art pump chamber heat insulation plate is shown in figure 1, which is composed of a plurality of heat insulation plate units, and the heat insulation plate units are fastened by bolts. The position where the hydraulic pump and its accessories pass is appropriately sealed with a seal strip.
The technical scheme of the existing pump chamber heat insulation plate can meet the arrangement requirements of the conventional power and hydraulic system of the excavator, and provides the functions of diversion, heat insulation and the like for the excavator. However, in the hybrid excavator, besides a hydraulic pump, a motor needs to be arranged in a pump chamber, and an output shaft of the engine is connected with a generator, which directly results in that the existing heat insulation plate structure cannot be installed; meanwhile, the existing heat insulation plate is formed by splicing a plurality of heat insulation plates, so that the splicing efficiency is low, the manufacturing cost is high, and the heat insulation and flow guide effects are poor.
SUMMERY OF THE UTILITY MODEL
The utility model aims at providing an excavator pump chamber heat insulating board to overcome among the prior art pump chamber heat insulating board can not satisfy the power of hybrid excavator and the defect of the thermal-insulated water conservancy diversion requirement between the pump chamber.
The utility model discloses an adopt following technical scheme to realize:
the excavator pump chamber heat insulation plate comprises a heat insulation plate body, wherein a mounting opening is formed in the heat insulation plate body, and the heat insulation plate body comprises two heat insulation plate units which can be spliced in a separable mode.
Furthermore, the surface of the heat insulation plate unit is fixedly provided with heat insulation cotton.
Further, the mounting opening is provided with a sealing strip.
Compared with the prior art, the beneficial effects of the utility model are that:
(1) the utility model discloses pump chamber heat insulating board is assembled by polylith heat insulating board unit through the bolt and is changed into two separable assemblings of thermal-insulated unit board, has promoted assembly efficiency, has reduced manufacturing cost.
(2) The utility model discloses the pump chamber heat insulating board is located between inboard aircraft bonnet frame and the outside aircraft bonnet frame, convenient dismantlement.
(3) The utility model discloses thermal-insulated cotton is pasted to pump chamber heat insulating board lateral surface, and it is sealed to use holistic sealing strip simultaneously, has increased thermal-insulated effect and leakproofness.
Drawings
FIG. 1 is a schematic diagram of a prior art pump chamber heat shield;
fig. 2 is a schematic structural diagram of the present invention;
fig. 3 is a usage state diagram of the present invention.
In the figure: 1. a heat insulation plate unit; 2. heat insulation cotton; 3. an installation port; 4. a sealing strip; 5. an upper frame; 6. a hydraulic pump; 7. an electric motor; 8. an outer hood frame; 9. a generator; 10. a pump chamber heat insulation plate; 11. an inner hood frame.
Detailed Description
The present invention will be further explained with reference to the accompanying drawings.
As shown in FIG. 2, the excavator pump chamber heat insulating board, including the heat insulating board body, be equipped with installing port 3 on the heat insulating board body, the heat insulating board body includes the heat insulating board unit 1 of two separable concatenations.
Furthermore, the surface of the heat insulation plate unit 1 is bonded with heat insulation cotton 2, and the heat insulation cotton 2 can obviously improve the heat insulation effect.
Furthermore, a sealing strip 4 is embedded in the mounting opening 3. The clearance between the pump chamber heat insulation plate 10 and the generator 9 is controlled uniformly, and the sealing strip 4 is embedded, so that the overall sealing effect is improved.
As shown in fig. 3, the pump chamber heat insulating plate 10 is mounted on the inner hood frame 11 by bolts, and is located entirely inside the hydraulic pump 6 and the motor 7 and above the upper frame 5. After the inner hood framework 11 is assembled, the pump chamber heat insulation plate 10 can be assembled, and then the outer hood framework 8 is assembled; when the pump chamber heat insulation plate 10 needs to be disassembled and replaced, the outer side hood framework 8 is disassembled firstly, and then the pump chamber heat insulation plate 10 is disassembled. Therefore, the problem that the heat insulation plate of the pump chamber of the hybrid excavator is difficult to disassemble and assemble is solved.
