Specific embodiment
For a better understanding of the present invention, below with specific embodiment come the technical solution that the present invention will be described in detail, still The present invention is not limited thereto.
Embodiment 1
As shown in Figure 1-3, present embodiments provide a kind of transmission line construction lifting crossing frame, including 2 brackets and 2 lead Messenger 1;Each bracket includes the hydraulic cylinder 3,2 of support base 2,2 hydraulic stem 4, keeps off terraced 5 and 2 drawstrings 6;Described in 2 The lower end of hydraulic cylinder 3 is hinged with the support base 2 respectively;One end of the hydraulic stem 4 and the support base 2 are affixed, separately One end and the hydraulic cylinder 3 are hinged;The gear ladder 5 includes 2 curb girders 7 and Duo Gen crossbeam 8;The both ends of the crossbeam 8 are solid respectively It is scheduled on 2 curb girders 7, and the interval setting that is parallel to each other between the crossbeam 8;One end of 2 curb girders 7 is respectively with 2 The top of the telescopic rod 9 of a hydraulic cylinder 3 is hinged;The inside top of 2 telescopic rods 9 is respectively equipped with pulley I10 and cunning Take turns II11;One end hinged with the telescopic rod 9 is not connect with 2 curb girders 7 respectively for one end of 2 drawstrings 6, another It hangs down after holding the top around the pulley I10;When 2 brackets are staggered relatively, 2 traction ropes 1 ride over 2 respectively The bracket is located on 2 pulley II11 of the same side.
The course of work of the present embodiment crossing frame is:
Before use, hydraulic cylinder 3 and hydraulic stem 4 are in retracted state, at this point, being kept off ladder 5 due to hydraulic cylinder 3 and support base 2 and being stretched Bar 9 is hinged, therefore hydraulic cylinder 3 and gear ladder 5 are folded state, i.e. 3 basic horizontal of hydraulic cylinder is placed in support base 2, and keeps off ladder 5 Basic horizontal is placed on hydraulic cylinder 3.
In use, 2 crossing frames to be individually positioned in the left and right sides for being spanned cable 16.By hydraulic cylinder 3 and hydraulic stem 4 It is connected with hydraulic pump, starts hydraulic pump, extend hydraulic stem 4, is placed until hydraulic cylinder 3 places rotation by basic horizontal to be vertical In support base 2, hydraulic pump driving hydraulic cylinder 3, stretches out the telescopic rod 9 in hydraulic cylinder 3, and drive on telescopic rod 9 at this time Gear ladder 5 move up, until telescopic rod 9 reach the height for being suitble to construction and gear ladder 5 opened after with the cable that is spanned Between be safe distance.Then, it is pulled through the drawstring 6 of pulley I10, gear ladder 5 is driven to open to horizontality, then by drawstring 6 Fixed, the gear ladder 5 for being spanned the crossing frame of cable two sides at this time forms an isolation platform, by construction cable and is spanned cable 16 isolation get up, prevent in work progress construct cable fall after be spanned cable 16 overlap joint.
After putting up crossing frame, one end of 2 traction ropes 1 is connected with one end of 2 cables to be onstructed respectively, And in auxiliary traction tool(Such as draw bar)Traction under, respectively drive 2 traction ropes 1 the other end be located at by 2 brackets The pulley II11 of the same side completes the leap of 2 cables to be onstructed to cable 16 is spanned, then by 2 lines to be onstructed Cable binding, is finally completed the crossing construction of electric line.Wherein, it draws, can be arranged in the other end of traction rope 1 for convenience Sling.After the completion of construction, crossing frame is withdrawn according to the mode opposite with crossing frame is built, for use next time.
Preferably, as shown in Figure 1, in the present embodiment, between 2 curb girders 7 and the hinged one end of the telescopic rod 9 Distance be less than not one end the distance between hinged with the telescopic rod 9.It is capable of increasing construction cable in this way and is spanned line Isolation area between cable 16, is more advantageous to guarantee construction safety.
When pulling drawstring 6 and traction rope 1, the shaking of rope body is inevitably generated, when careless manipulation leads to body rolling of restricting When dynamic excessively violent, rope body can be made to slip from pulley, cause drawstring 6 or traction rope 1 to fall on gear ladder 5, continue at this time Rope body is pulled, not only arduously, and rope body can be worn, cause unnecessary loss.To solve this problem, as shown in figure 4, at this In embodiment, on the telescopic rod 9, it is equipped with around the pulley I10 and pulley II11 for the drawstring 6 and traction The frame 12 that rope 1 passes through.Rope body is limited on pulley by frame 12, the slippage of rope body is effectively prevented, has ensured and applied Work is gone on smoothly, and avoids unnecessary loss.
For the ease of the movement of crossing frame, the bottom end of the support base 2 is equipped with idler wheel 15.
In order to improve the safety and stability of construction, the support base 2, gear ladder 5, pulley I10 and pulley II11 are equal It is made of epoxide resin material, the traction rope 1 and drawstring 6 are made of insulating material.
Embodiment 2
As illustrated in fig. 1 and 2, it is in place of the present embodiment and the difference of embodiment 1:It further include 4 with externally threaded fixed link 13; Be respectively equipped with tapped through-hole 14 on four angles of the support base 1, the support base 1 by the through-hole 14 with Fixed link 13 is threadedly coupled.
Crossing frame is placed on after the two sides for being spanned cable 16, when pulling drawstring 6 and traction rope 1, may be made Support base 2 moves on the ground, influences the stability of operation.It is threaded with fixed link 13 in the four corners of support base 2, After crossing frame is placed in place, rotation fixed link 13 is until ground is inserted into its bottom end, it is preferable that the fixed link 13 bottom end is pointed shape, so that fixed link 13 is easier to insertion ground, so as to fix support base 2 on the ground, just Stablize in subsequent construction and carries out.
Specific embodiments of the present invention are described in detail in conjunction with attached drawing above, but the present invention is not limited to above-mentioned realities Apply the detail of example, those skilled in the art's modification made within the scope of technical solution of the present invention, Addition or replacement, also belong to protection scope of the present invention.
It can also be with it is further to note that in the case of no contradiction, between each different embodiment of the invention Any combination, as long as it does not violate the idea of the present invention, it should also be regarded as the disclosure of the present invention.
