Detailed Description
The present invention will be described in further detail with reference to the accompanying drawings.
The first embodiment is as follows:
referring to fig. 1 and 2, for the utility model discloses a foldable guardrail in aerial working platform, including base station 1, base station 1 is the rectangle platform, all is equipped with guardrail 2 on 1 each side of base station, the bottom fixedly connected with articulated shaft 22 of guardrail 2, equal fixedly connected with hinge ring 12 on 1 each lateral wall of base station, and guardrail 2 is articulated with base station 1 through hinge ring 12 and articulated shaft 22's cooperation. Because articulated ring 12 is higher than the top surface of base station 1, and then can rotate to the position parallel with base station 1 when guardrail 2 emptys to base station 1 inboard, be convenient for the staff to use aerial working platform to transport construction material when putting each guardrail 2 flat.
Referring to fig. 1 and 2, a first limiting rod 21 rotating in a vertical plane is hinged to the side wall of the guardrail 2 facing the base 1, a second limiting rod 11 is hinged to one side, away from the guardrail 2, of the first limiting rod 21, and one side, away from the first limiting rod 21, of the second limiting rod 11 is hinged to the base 1. The first limiting rod 21 and the second limiting rod 11 are provided with positioning parts 3 for limiting the mutual rotation of the two limiting rods. The positioning member 3 includes a limiting sleeve 31 and a limiting boss 32, the limiting sleeve 31 is sleeved on the first limiting rod 21 and is matched with the first limiting rod 21, and the limiting boss 32 is located on the second limiting rod 11. When the limiting sleeve 31 falls down to be abutted against the limiting boss 32 in the limiting sleeve 31, the hinged position of the first limiting rod 21 and the second limiting rod 11 is located on the inner side of the limiting sleeve 31, and the limiting sleeve 31 restrains the relative rotation of the first limiting rod 21 and the second limiting rod 11, so that the whole limiting rod formed by the first limiting rod 21 and the second limiting rod 11 limits the guardrail 2, and the guardrail 2 is kept in a state perpendicular to the base platform 1.
Referring to fig. 1, a first accommodating groove 211 is formed in a side wall of a rod of the guardrail 2 perpendicular to the hinge shaft 22, the side wall faces the first limiting rod 21, a second accommodating groove is formed in the upper surface of the base platform 1, and when the guardrail 2 rotates to be parallel to the upper surface of the base platform 1, a part of the first limiting rod 21 and a part of the second accommodating groove are located in the first accommodating groove 211 and the second accommodating groove 111 respectively, so that the possibility that the guardrail 2 cannot be squared due to the fact that the guardrail 2 is obstructed in motion is reduced.
The implementation principle of the embodiment is as follows: when the staff need expand guardrail 2, at first pull up guardrail 2, guardrail 2 is in the in-process to vertical state pivoted, first gag lever post 21 and second gag lever post 11 mutual rotation to the state that is parallel to each other gradually, spacing sleeve 31 is contradicted to with spacing boss 32 because self gravity lapse this moment, thereby restrict the mutual rotation of first gag lever post 21 and second gag lever post 11, it is spacing to carry out the support to guardrail 2 on the same straight line to make first gag lever post 21 and second gag lever post 11, when needs use high altitude construction platform transportation construction materials, the staff pulls up the lantern ring and can rotate guardrail 2 and make guardrail 2 fold to 1 direction of base station, the expansion and the folding easy operation of guardrail 2, convenient and fast.
Example two:
referring to fig. 3, the internal folding guardrail 2 of the aerial work platform is different from the first embodiment in that:
referring to fig. 3 and 4, guardrail 2 is telescopic link 4 with articulated shaft 22 vertically pole, telescopic link 4 is located 2 length direction's of guardrail both sides, telescopic link 4 includes telescopic sleeve 42 and interior pole 41, the cross-section of interior pole 41 is square, telescopic sleeve 42 is pole 41 in the half surrounding structure cladding, the open end orientation one side that is close to each other of two telescopic sleeve 42, common fixedly connected with bar 43 on two interior poles 41, bar 43 rushes the open end respectively with interior pole 41 fixed connection, the last cladding of bar 43 has slipmat 432 (refer to fig. 6). The inner rod 41 is provided with a positioning bolt 431, the positioning bolt 431 penetrates through the inner rod 41 and is in threaded connection with the inner rod 41, one end of the positioning screw rod, which is positioned in the telescopic sleeve 42, is abutted against the inner side wall of the telescopic sleeve 42, and the other end of the positioning screw rod, which is positioned in the telescopic sleeve 42, extends out of the opening end of the telescopic sleeve 42 and is connected with a rotating handle. After the worker rotates the rotating handle to separate the inner side walls of the telescopic sleeves 42 at the end parts of the positioning bolts 431 on the two telescopic rods 4, the inner rod 41 is partially pulled out of the telescopic sleeves 42 by pulling the handrail, and the positioning bolts 431 are screwed again to position the inner rod 41 after the height is adjusted. Thereby be convenient for the staff according to the rising readjustment handrail height of self, reduce the hindrance of handrail to the construction when guaranteeing 2 guard action of guardrail.
Referring to fig. 3 and 5, base station 1 is except the lateral wall towards the construction surface, equal fixedly connected with along a plurality of connecting strips 51 of vertical direction extension on two other minor face lateral walls and a long limit lateral wall, a plurality of connecting strips 51 are located each lateral wall length direction's both ends respectively, draw-in groove 52 has all been seted up on the relative lateral wall of connecting strip 51 on the same lateral wall, and two connecting strip 51 bottoms on the same lateral wall are connected with locking strip 53 jointly, same deep bead 5 is equipped with in the common insertion of draw-in groove 52 of two connecting strips 51 on the same lateral wall, deep bead 5 adopts the transparent plastic material. The wind shield 5 shields strong wind for workers, provides a relatively comfortable working environment for the workers, particularly in winter, shields cold wind, can reduce cold feeling of the workers, prolongs continuous working time and improves working efficiency.
The embodiment of this specific implementation mode is the preferred embodiment of the present invention, not limit according to this the utility model discloses a protection scope, so: all equivalent changes made according to the structure, shape and principle of the utility model are covered within the protection scope of the utility model.
