Abstract
The utility model provides a water cooling circuit device for a bottom plate of an electric cabinet, which overcomes shortcomings of large metal cutting amount and long processing time of an existing water cooling circuit on a bottom plate of an electric cabinet of a coal mining machine. The deep-hole type water cooling circuit device is mainly characterized in that a plurality of rows of deep holes are drilled along the thickness direction of the bottom plate, axes of the deep holes are parallel to the surface of the bottom plate, pin plugs are welded and sealed at apertures of the deep holes, a communicating water channel is disposed between each two rows of adjacent deep holes so that the two rows of adjacent deep holes are communicated with each other, one of each two adjacent communicating water channels is disposed at the upper ends of the deep holes while the other one is arranged at the lower ends of the deep holes, and consequentially, all main cooling water channels are connected into a pulse-wave-shaped cooling water channel. The deep-hole type water cooling circuit device has the advantage of capability of substantially reducing welding and metal cutting amounts of a steel plate sealed water channel.
Description
Technical field
The utility model relates to the water cooling loop apparatus on the coal-winning machine electric cabinet base plate.
Background technology
Water cooling loop on the existing coal-winning machine electric cabinet base plate mills by T type rectangular channel, groove top steel plate solder up, and rectangular opening is stayed in the centre, forms the water system loop.The defective of this technology is that the metal cutting amount is big, long processing time; The 2nd, the whole loop of rectangular channel all needs the welding steel water shutoff, and to form water loop, welding capacity is big, can not guarantee after the welding that bulge test reaches a standard, and secondary welding influences electric cabinet manufacturing cycle and cost often greatly; The 3rd, rectangular channel is big because of relating to welding capacity, is subjected to huge welding stress during the base plate welding, needs to increase the destressing technical process, increases production process and cost, influences the electric cabinet production cycle.
Summary of the invention
For solving the problems of the technologies described above, the purpose of this utility model is to provide a kind of deep hole formula electric cabinet base plate water cooling loop apparatus.
The purpose of this utility model is achieved in that and is drilled with the plurality of rows deep hole as the cooling main channel on base plate thickness, the axis of this deep hole is parallel with the base plate face, stifled aperture and the sealing that is welded on deep hole of pin, between two adjacent row's deep holes, open the connection water channel, two adjacent row's deep holes are communicated with, upper end of adjacent connection water channel at deep hole, lower end at deep hole, all cooling main channel are connected into the impulse waveform cooling water channel, the method that processing is communicated with water channel is to open a section to be the groove of falling the convex shape on base plate, cover plate is embedded in the groove of upper strata and welding fixing, lower floor's groove forms and is communicated with water channel.Before using bulge test is carried out in the water channel loop, pressure 3MPa, pressurize 10 minutes must not seepage.
Compared with prior art, the beneficial effects of the utility model are:
A) by selecting the diameter of lengthening drill bit, can guarantee the area coverage and the empty diameter of section of water loop, guarantee the film-cooled heat of cooling water channel and the water yield by base plate, thereby guarantee normal cooling related electric components and parts.
B) according to position and the caloric value of coal-winning machine with electric components on the automatically controlled box plate, calculate the need cooling water inflow of each components and parts, determine the parameters such as position, pitch of holes and hole diameter of section of cooling water channel, form arrangement.
C) reduce the welding capacity in steel plate water shutoff road significantly, reduce the metal cutting amount that base plate adds man-hour significantly, shorten process time.
D) because of welding capacity is few, save and go the welding stress operation, reduce workpiece manufacture cost and cycle.
Description of drawings
Further specify the utility model below in conjunction with accompanying drawing.
Fig. 1 is a schematic diagram of the present utility model.
Fig. 2 is the vertical view of Fig. 1.
Fig. 3 is the A-A cutaway view of Fig. 2.
Fig. 4 is the B-B cutaway view of Fig. 1.
Embodiment
On the thickness of base plate 1, be drilled with the plurality of rows deep hole as cooling main channel 4, the axis of this deep hole is parallel with the base plate face, pin stifled 3 is welded on the aperture and the sealing of deep hole, between two adjacent row's deep holes, open and be communicated with water channel 2, two adjacent row's deep holes are communicated with, upper end of adjacent connection water channel at deep hole, lower end at deep hole, all cooling main channel 4 are connected into the impulse waveform cooling water channel, referring to Fig. 4, the method that processing is communicated with water channel is to open a section to be the groove of falling the convex shape on base plate, cover plate 5 is embedded in also to weld in the groove of upper strata fixes, and lower floor's groove forms and is communicated with water channel 2.Before using bulge test is carried out in the water channel loop, pressure 3MPa, pressurize 10 minutes must not seepage.
