Description

Moso Bamboo Crossing Frame

technical field

The utility model relates to a tool used in the leaping construction of power transmission and transformation power lines, in particular to a moso bamboo spanning frame used in live electricity crossing 110kV and below power lines, roads, railways and buildings.

Background technique

In the construction process of spanning overhead lines, spanning frames are usually used to cross over highways, railways, communication lines or existing transmission lines, and spanning frames are erected according to the needs of on-site crossings. The spanning frame used in the railway is complex, heavy, and has a low safety factor. After the spanning construction is completed, the operation of dismantling the spanning frame is cumbersome, requiring a lot of manpower and time, which affects the construction progress.

Contents of the invention

The purpose of the utility model is to solve the above-mentioned existing problems, and to provide a moso bamboo spanning frame which is simple in structure, light, economical and convenient to set up and dismantle.

In order to achieve the above-mentioned purpose, the moso bamboo straddling frame designed by the utility model comprises two parallel-arranged frame bodies erected by moso bamboo. The top surface of the frame body is connected with an insulating protective net, and a plurality of anchor ropes are connected between the frame tops of the two moso bamboo frame bodies and the ground.

In the above technical solution, the frame body includes a plurality of upright poles, forward crossbars, transverse crossbars and ejector poles to form a cage, the upright poles are perpendicular to the ground and are arranged in at least two rows, and the forward crossbars The rods and the horizontal cross bars are connected to the vertical poles in a row parallel to the ground, and the longitudinal cross bars and the horizontal cross bars are arranged perpendicular to each other. The top poles are connected to the top of the vertical poles and arranged inclined to the ground.

Further, the frame body also includes a plurality of forks connected to the vertical poles, the forks form an acute angle with the ground, and two adjacent forks form a triangular structure with the ground.

Furthermore, the forward cross bar and the transverse cross bar are fixed on the vertical pole by binding.

Further, an "X" shaped nylon rope is connected between the top four corners of the two frames.

Further, rollers are installed on the tops of the two frames.

The moso bamboo spanning frame designed by the utility model has a frame body set up outside the safe distance on both sides of the spanned line. The frame materials are all made of moso bamboo, which has the advantages of lightness, insulation, and economy. The entire spanning frame is light, insulating, and stable. ;Use oblique fork rods on the side of the frame, using the principle of triangular stability to increase the stability of the frame; the four corners of the top of the frame are connected with nylon ropes to form an "X"-shaped support, which can effectively prevent new lines The wires slide down from the nylon mesh rope gap; install rollers on the top surface of the frame, and each wire is equipped with two rollers. When the wires fall on the rollers, the low-resistance rotation of the rollers can reduce the damage to the wires. The moso bamboo and nylon net on the top of the protective frame can meet the requirements of live spanning construction; after the construction is completed, the entire spanning frame can be removed from top to bottom in the opposite direction of installation and erection, which is easy to dismantle and easy to operate.

Description of drawings

Fig. 1 is the structural representation of the embodiment of the utility model;

In the figure: 1. frame body (1.1, vertical pole; 1.2, forward horizontal bar; 1.3, horizontal horizontal bar 1.4, fork pole 1.5, jacking pole;) 2, insulating net; 3, anchor rope; 4, nylon rope ; 5. Drum; 6. New line; 7. Object to be crossed.

Detailed ways

Below in conjunction with accompanying drawing and embodiment the utility model is described in further detail.

The bamboo spanning frame as shown in Figure 1 comprises two frame bodies 1 arranged in parallel that moso bamboo is set up, the cross section of frame body 1 is trapezoidal, and the top surface of frame body 1 is a slope inclined downwards, between the two frame bodies An insulating protective net 2 is connected to the top surface, and a plurality of anchor ropes 3 are connected between the frame tops of the two moso bamboo frame bodies and the ground.

The frame body 1 includes a plurality of vertical poles 1.1, forward horizontal bars 1.2, horizontal horizontal bars 1.3, fork poles 1.4 and jacking poles 1.5 to form a cage. The vertical poles 1.1 are perpendicular to the ground and at least two rows are arranged, and the forward horizontal bars 1.2 The horizontal bar 1.3 is parallel to the ground and is connected in a row on the vertical pole 1.1, and the forward horizontal bar 1.2 and the horizontal bar 1.3 are fixed on the vertical pole 1.1 by binding. The forward cross bar 1.2 and the horizontal cross bar 1.3 are arranged perpendicular to each other, the top pole 1.5 is connected to the top of the vertical pole 1.1 and arranged inclined to the ground, the fork pole 1.4 forms an acute angle with the ground, and the two adjacent fork poles 1.4 form a triangle with the ground The structure uses the triangular stability principle to increase the stability of the frame.

Along the direction of the new line 6 on the outside of the frame body, a number of anchor ropes are arranged from the top of the frame to the ground. The anchor ropes are connected in series with double hooks, which can adjust the tension of the anchor ropes. After the frame is erected, a nylon net is made from one end to the other with a nylon rope between the poles on both sides of the frame. Seal into " X " shape between four jiaos of frame body top with nylon rope at last, prevent the lead wire of newly-built circuit 6 from slipping between nylon mesh rope gap. Finally install the rollers on top of the frame. There is one drum for each wire, when the wire falls on the drum, the low resistance rotation of the drum can not only reduce the damage to the wire, but also protect the moso bamboo and nylon net on the top of the frame.

When erecting from bottom to top, the large head of the vertical pole 1.1 is tamped vertically downwards before binding. The horizontal bar 1.3 is set on the outside of the spanned object 7. Tools, materials and operators must be on the outside of the horizontal bar 1.3. , When the high-voltage line is erected across the frame, it must be supervised by a special person, and when the moso bamboo is passed, a safe distance from the charged body must be ensured.

When dismantling, it should go up and down first. Before dismantling, check the weak links. After reinforcement, first remove the capped horizontal bar 1.3 and forward bar 1.2. The upper and lower sides are dismantled at the same time, and at the same time, it is avoided to overthrow or dismantle the spanning frame as a whole.

The bamboo type spanning frame of the utility model is suitable for spanning electric power lines of 110kV and below, and is also suitable for spanning roads, railways, buildings, etc., and has a stable structure, safety and reliability.
