Background technology
At present China's high-voltage motor development is very fast, and the corresponding backwardness of the starting device that matches with it, the liquid soft start is the soft start of a kind of current collection machine, soft stop, light-load energy saving and multi-protective function are in novel motor control assembly together.Electrohydraulic box is one of core of this device, and liquid resistance starting (moving, fixed) pole plate is installed in the case, realizes the soft start of high-voltage high-power motor in the main engine starting process by the distance between the control break pole plate.Be provided with in the case that liquid level is excessively low, liquid temperature is crossed high protective device, only normal in casing serviceable condition (comprising liquid temperature, liquid level) output, moving fixed plate position is suitable, and main frame just can carry out start-up function.Be this performance to electrohydraulic box, it is very important that material, production technology, quality requirement seem.
In recent years, the electrohydraulic box of the liquid soft starter device that the most enterprises of China produce, all be with plastic plate welding, bonding or be made with fiberglass hand formulating method, not only quality can't guarantee, and be difficult to realize standardization, large-scale production, especially the fragility of fiberglass is obvious, and the stretch-proof extrusion performance is poor, easily cracking or damaged and be difficult to repair; And the electrohydraulic box of making of plastic plate welding, adhering method, its junction stress is difficult to eliminate, with the weld seam that expands with heat and contract with cold, cemented side seam inevitably box deformation, cracking can appear, then cause leakage, electric leakage, electric motor starting equipment can't be worked, not only cause the pollution of environment also directly to affect the usage safety performance of electrohydraulic box.
Summary of the invention
The purpose of this utility model is exactly for existing technique, the existing above-mentioned deficiency of technology, and provides a kind of bulk strength high, and can high voltage withstanding, high temperature resistant, corrosion resistant rotational molding one-shot forming electrohydraulic box.
Technical solution of the present utility model is: a kind of rotational molding one-shot forming electrohydraulic box, comprise casing, and it is characterized in that: described casing is one-time formed integral type casing; This casing is provided with the in-flanges reinforcement along one week of case mouth, in the casing side groove type reinforcement is set; Between the side and side of casing, be arc chord angle between side and the bottom surface.
Be provided with one-time formed fixed plate boss carriage in described tank floor in the technical solution of the present utility model.
Groove type reinforcement described in the technical solution of the present utility model is the 6 roads reinforcements vertical with the in-flanges reinforcement, minute is located at two of casings relatively and on the larger side.
Boss carriage described in the technical solution of the present utility model is that 4 roads are two row, the symmetrical boss carriage of two rows, forms electric liquid passage between this 4 road boss carriage.
The utility model is owing to adopt one-time formed integral type casing, and be provided with the in-flanges reinforcement along one week of casing case mouth, in the casing side groove type reinforcement is set, between the side of casing and side, between side and the bottom surface, adopt arc chord angle to be connected, thereby can avoid plastic plate welding, bonding and handwork defective that hand is stuck with paste the fiberglass electrohydraulic box fully, thoroughly avoided the caused tension intensity of welding cemented side seam not enough, easy strain cracking, cause leakage, electric leakage to cause security incident, cause soft-start device to work.The utility model is owing to be provided with one-time formed fixed plate boss carriage in tank floor, thereby need not secondary welding, and both strengthened the bottom half support strength, also make fixed plate installation location more firm, the electric liquid passage that 4 road boss tray chambers arrange makes the battery lead plate heat radiation more balanced.The utility model has not only highlighted good looking appearance; inherent quality is good, security performance is high; and effectively simplify manufacture craft; reduced labor strength; improved production efficiency; also reduce to greatest extent simultaneously the materials of electrohydraulic box, reduced production costs, be suitable for mass, large-scale production.The utility model is mainly used in can high voltage withstanding, high temperature resistant, corrosion resistant electrohydraulic box.
Description of drawings
Fig. 1 is the main apparent direction structural representation of a kind of embodiment of the utility model.
Fig. 2 is the left apparent direction sectional structure schematic diagram of structure shown in Figure 1.
Fig. 3 be structure shown in Figure 1 overlook the direction structure schematic diagram.
Among the figure: casing 1, case mouth periphery in-flanges reinforcement 2, casing lateral grooves reinforcement 3, bottom half is moving, fixed plate boss carriage 4, electric liquid passage 5, arc chord angle 6.
Embodiment
As shown in Figure 1 to Figure 3.Electrohydraulic box casing 1 is to adopt macromolecule polymeric material (polythene PE, polypropylene PP) structure, by the Rotational Molding one-shot forming.During making polythene PE or polypropylene PP powdered plastic are joined in the electrohydraulic box mould, then by heating mould and make it along orthogonal two axles continuous rotation in the situation of different rotating speeds, powder in the mould under the effect of gravity and heat progressively evenly melting adhere on the mould inner wall, thereby form the box shape of hollow, then make product through cooling and demolding.
In case mouth periphery in-flanges reinforcement 2 structures, form an overall structure with casing 1 four sides, the case mouth torsional deformation of having avoided secondary welding to cause, the defective such as case lid and case mouth are poorly sealed, the evenness that has improved the case mouth has increased the support strength of case mouth.
Be provided with 6 road groove reinforcements 3 in 1 liang of large side of casing, make and increased the ventilation and heat space between chest, not only can control the contraction distortion on casing 1 large plane, also improved the bulk strength of casing 1, can reduce on former casing materials basis simultaneously the materials amount of 10%-15%, reduce production cost.
Be provided with 4 road fixed plate boss carriages 4 in the electrohydraulic box bottom, with the bottom surface be that an integral body need not secondary welding, both strengthened the bottom half support strength, it is more firm also to make fixed plate that the location is installed, the electric liquid passage 5 that 4 road boss tray chambers arrange makes the battery lead plate heat radiation more balanced.
Between the side of casing 1 and side, between side and the bottom surface, be connected for arc chord angle 6, adopted the design of the orthodrome angle of cut, overcome the drawback of large flat square structure, be more suitable for the moulding of rotational molding process, it is more even that material is distributed in die cavity, the product wall thickness is consistent, has avoided the existence of plastic plate welding, gluing stress, has reduced the electrohydraulic box distortion.
The one-time formed electrohydraulic box of the utility model rotational molding has obvious advantage: at first, the casing good integrity, the solderless seam, casing is difficult for producing distortion, long service life without residual stress; The second, from material property, have good mechanical property, electrical insulation capability, high temperature (can be at 80-110
0C) indeformable under the operational environment, non-leakage, corrosion-resistant, ageing resistace is used more safe and reliable; The 3rd; adopt the one-time formed electrohydraulic box of rotational molding, overcome the weak point with plastic plate welding, gluing, fiberglass manual pasting forming process fully, replace the labour intensity that manual work mode reduces the workman; enhance productivity, can realize standardization, large-scale production.
