Embodiment
For technological means, creation characteristic that the present invention is realized, reach purpose and effect and be easy to understand and understand, below in conjunction with concrete diagram, further set forth the present invention.
Instance 1
Referring to Fig. 1, the steel body trolley 100 that relates among the present invention mainly is made up of with the copper conductor 102 that is placed in iron-based 101 tops the iron-based 101 of bottom.
The cross section of iron-based 101 is inverse-T-shaped, and its top is provided with swallow-tail form and settles piece 101a.
Improve above-mentioned rigid body trolley 100 performance in use; The present invention is parcel one deck insulating sleeve 200 in the outside of rigid body trolley 100; Parcel through insulating sleeve 200 makes that dust can't cover rigid body trolley 100 in the air, effectively guarantees the stability that rigid body trolley 100 uses; Because the buffer action of insulating sleeve 200 makes external object can't directly touch rigid body trolley 100, the fail safe that effectively improves rigid body trolley 100 makes it can be applicable to that some are prone to the occasion of contact simultaneously.For avoiding parcel and isolation owing to insulating sleeve 200; It can't be cooperated with current-collector; The present invention also offers at insulating sleeve 200 and is used for copper conductor top wiping face contacts power taking with the current-collector cooperation notch 2021a, has guaranteed the function of rigid body trolley 100 through this notch 2021a.
As shown in Figure 2, insulating sleeve 200 constitutes by the corresponding insulation material is one-body molded, comprises being used to wrap up the insulation crust 201 of rigid body trolley iron-based 101 and be set in insulating cover 202 two parts on the rigid body trolley copper conductor 102.
For guaranteeing that insulation crust 201 has certain intensity and protection, the shell thickness of this insulation crust 201 is consistent.
Moreover, being placed among the resettlement groove 201a for the ease of iron-based 101, this instance is provided with some protruding 201b in the bottom of resettlement groove 201a.The cross section of these protruding 201b is a circular arc, and along the bearing of trend setting of resettlement groove 201a bottom, protruding 201b evenly distributes on the Width of resettlement groove 201a bottom simultaneously.Through support and the guide effect of arc-shaped convex 201b, make iron-based 101 effectively to overcome and resettlement groove 201a inwall between resistance, be placed in fast among the resettlement groove 201a.
Referring to Fig. 2, be positioned at the insulating cover 202 on insulation crust 201 tops, be used for copper conductor 102 is formed protection.It is set on the copper conductor 102; Offering some copper conductor top wiping faces contact power taking with the current-collector cooperation notch 2021a that are used for the corresponding top of wiping face, copper conductor 102 top; And insulating cover 202 is through the support of self elastic force; Make the top of insulating cover 202 under the situation of no external force effect, not contact, thus copper conductor 102 is formed insulation protection with the wiping face at copper conductor 102 tops.
Thus, in this instance, insulating cover 202 mainly is made up of a protective bulkhead 2021, two supporting walls 2022 and two elastic walls 2023.
Wherein, protective bulkhead 2021 matches with copper conductor 102 top wiping faces, and copper conductor 102 top wiping faces are formed protection, offers some copper conductor top wiping faces that are used on it and cooperates the notch 2021a that contacts with current-collector.
Referring to Fig. 3, the rectangle notch of notch 2021a for offering along protective bulkhead 2021 Widths, the width of concrete length and copper conductor 102 matches; On the bearing of trend (being the bearing of trend of copper conductor 102) of protective bulkhead 2021, notch 2021a adopts the mode of equidistance to distribute.The protective bulkhead 2021 that forms thus not only can form insulation protections to copper conductor 102 top wiping faces, can guarantee that the stability and the current-collector that cooperate between copper conductor 102 top wiping faces and the current-collector can pick up enough electric weight simultaneously again.
Two supporting walls 2022 are used to support protective bulkhead 2021, and it is symmetricly set on the both sides of protective bulkhead 2021.For forming support effect well, two supporting walls 2022 join with protective bulkhead 2021 to both sides respectively at an angle, and concrete angle can be decided according to actual conditions, specifically can be 120 °, 145 ° etc.
Two elastic walls 2023 are respectively applied for and connect two supporting walls 2022 and insulation crust 201; Elastic wall 2023 can produce elastic force upwards to the supporting walls 2022 that joins with it simultaneously; Make supporting walls 2022 under the effect of this power, form support upwards, make protective bulkhead 2021 under the situation that does not have downward external force effect, remain the state that does not contact copper conductor top wiping face protective bulkhead 2021.
For making elastic wall 2023 have lasting and stable elastic force, the elastic wall 2023 in this instance mainly comprises the first arcwall 2023a, linking arm 2023b and the second arcwall 2023c.
The end of the first arcwall 2023a and the free end of supporting walls 2022 join, and the bending direction of first arcwall is towards the insulating cover outside, and the arc opening level of its formation upwards.
Linking arm 2023b horizontal direction is provided with, and the other end of the one of which end and the first arcwall 2023a joins, and the end of the other end of linking arm 2023b and the second arcwall 2023c joins.
The other end of the second arcwall 2023c joins as the link and the insulation crust 201 of insulating cover, and the bending direction of the second arcwall 2023c is inboard towards insulating cover.
The elastic wall 2023 that forms thus realizes producing lasting and stable elastic force through the cooperation between the arcwall.
The consistency of thickness of the first arcwall 2023a, the second arcwall 2023c and linking arm 2023b in the scheme of above-mentioned elastic wall 2023 can further improve the effect of elastic wall 2023 like this.
In practical application, the length of the radian of the first arcwall 2023a and second arcwall 2023c size and linking arm 2023b can be decided according to actual conditions.
Shown in Figure 4 for adopting such scheme to form dust-protection type safety rigid body trolley; Directly assign into rigid body trolley correspondence in the insulating sleeve in use; This moment the insulation crust iron-base partially that wraps the rigid body trolley tightly in the insulating sleeve, the insulating cover in the insulating sleeve then is enclosed within on the copper conductor of rigid body trolley.This moment, the elastic force that elastic wall produces in the insulating cover remained at protective bulkhead the state that does not contact copper conductor top wiping face when not being used with current-collector.
Because rigid body trolley safety is in the insulating sleeve, dust can't be covered on the rigid body trolley at all, makes it have good dustproof effect.
In use; The energising of rigid body trolley; Current-collector is placed on the rigid body trolley, and current-collector will produce downward power to protective bulkhead this moment, and overcome the elastic force of elastic wall; Make protective bulkhead move down and contact that current-collector will contact with copper conductor top wiping face through the notch on the protective bulkhead and pick up electric weight this moment with copper conductor top wiping face on the rigid body trolley.The size of notch and distributed quantity can guarantee that current-collector picks up enough electric weight when contacting with the rigid body trolley.
When current-collector when trolley moves, along its moving direction constantly with the protective bulkhead in the insulating cover on the copper conductor to pressing down, and contact with copper conductor top wiping face.Break away from the part of current-collector pressure in the protective bulkhead, under the effect of elastic wall elastic force, will return to the state that does not contact copper conductor top wiping face.
Thus, the rigid body trolley of energising has only the part that contacts with current-collector just to join with the external world, and remainder all is in the insulation protection of insulating sleeve, safety very.
