Description
Technical field
The utility model relates to a kind of pressing plate throwing and moves back device.
Background technology
The protection pressing plate is the more and frequent element that needs operation of transformer station's usage quantity; the operation that it usually need drop into or withdraw from along with the state of main equipment; the input of so-called protection pressing plate is meant with after in flakes its top and the bottom being communicated with, again the operation that top nut and lower nut are tightened.The withdrawing from of so-called protection pressing plate is meant unclamps its top nut and lower nut the operation that will open in flakes more earlier.Traditional mode of operation is directly to tighten or unclamp lower nut on it with hand, has following shortcoming: to need to drop into or withdraw from protection pressing plate quantity many because of each operation, so waste time and energy; The strength that the operator uses is different, the motionless phenomenon of pine when normal appearance protection pressing plate need withdraw from; The protection pressing plate is when dropping into, and two nuts all will be tightened up and down, leak nutting easily and cause loose contact.
The utility model content
The utility model purpose is to provide a kind of easy to operate pressing plate to throw and moves back device.
To achieve these goals, the utility model adopts following technical scheme: pressing plate is thrown and is moved back device, comprise housing, the upper and lower gear that is provided with travelling gear in the housing and is meshed with travelling gear respectively, the axle outer end of travelling gear is provided with turning handle, axle the inner of upper and lower gear is respectively equipped with upper and lower sleeve, distance between the upper and lower nut of distance between the upper and lower sleeve and pressing plate equates, upper and lower sleeve is provided with the little wedged hole of outer imperial palace, and a perisporium is provided with the raised tooth of extending along the hole depth direction in the hole.
Described upper and lower sleeve rear end is provided with quill shaft, and the outer section of quill shaft section diameter is greater than sleeve inner segment part, and the inner of the outer section part of quill shaft and the distance values between the housing are less than the numerical value of the precession degree of depth of the upper and lower nut of pressing plate; Square gear shaft endoporus is set in the gear shaft of upper and lower gear, and the quill shaft inner segment partly is provided with the square cylinder structure and is located in the gear shaft endoporus; The outer end of quill shaft inner segment part is provided with the adjusting nut, regulates the diameter of the cap body diameter of nut greater than the gear shaft endoporus; Between upper and lower sleeve and the last lower gear spring is set.
On the housing that is provided with upper and lower sleeve one side, be provided with support.
Described housing comprises header board and back plate, between header board and the back plate fixed support is set, and between header board and the back plate travelling gear is set, cogs and lower gear.
The utility model has following advantage: the protection pressing plate is thrown when moving back the device use easy to carry, and flexible operation is reliable, saves the operating time of dropping into or withdrawing from the protection pressing plate; Use the protection pressing plate to throw and move back device input protection pressing plate, compress the strength basically identical, do not exist different operators because of the different phenomenons that are difficult to become flexible of strength; After using the throwing of protection pressing plate to move back device input protection pressing plate, it contacts up and down well, and the electric loop performance is unaffected; Use the protection pressing plate to throw when moving back device, support and the protection screen plane contact, stablize nonvoluntary swing during operation.
The outer section of quill shaft section diameter partly forms stop greater than the sleeve inner segment; can guarantee the upper and lower nut that when withdrawing from the protection pressing plate, do not come loose; when dropping into the protection pressing plate, be unlikely stubborn too tight, make different users when operation aeration level with compress strength and manage consistent.Between upper and lower sleeve and the last lower gear spring is set, when operation, can moves forward and backward along with the rotation of the upper and lower nut of protection pressing plate.Upper and lower sleeve is provided with the little wedged hole of outer imperial palace, is easy to block the last lower nut of protection pressing plate during use.

Embodiment
Embodiment: the pressing plate shown in Fig. 1-6 is thrown and is moved back device, comprise housing, housing comprises header board 1 and back plate 5, between header board 1 and the back plate 5 fixed support 6 is set, between header board 1 and the back plate 5 travelling gear 10 is set, cog 2 and lower gear 4, on, lower gear 2,4 are meshed with travelling gear 10 respectively, the axle outer end of travelling gear 10 is provided with turning handle 3, on, lower gear 2, axle the inner of 4 is respectively equipped with, lower sleeve 8,9, on, lower sleeve 8, on distance between 9 and the pressing plate, distance between the lower nut equates, on, lower sleeve 8,9 are provided with the little wedged hole of outer imperial palace, and a perisporium is provided with the raised tooth of extending along the hole depth direction in the hole.
Upper and lower sleeve 8,9 rear ends are provided with quill shaft, and the outer section of quill shaft part 11 diameters are greater than sleeve inner segment part 13, and the inner of the outer section of quill shaft part 11 and the distance values between the housing are less than the numerical value of the precession degree of depth of the upper and lower nut of pressing plate; Square gear shaft endoporus is set in the gear shaft of upper and lower gear 2,4, and quill shaft inner segment part 12 is provided with the square cylinder part and is located in the gear shaft endoporus; The outer end of quill shaft inner segment part 12 is provided with regulates nut 14, regulates the diameter of the cap body diameter of nut 14 greater than the gear shaft endoporus; Between upper and lower sleeve 8,9 and the last lower gear 2,4 spring 13 is set.On the housing that is provided with upper and lower sleeve 8,9 one sides, be provided with and support 7.
