Description

An auxiliary device for laying control cables

technical field

The invention relates to the technical field of electric power construction, in particular to an auxiliary device for laying control cables.

Background technique

In the construction of substation engineering, the laying method of transmission control cables is generally from the downstairs of the control room to the upstairs control room through the windowsill, and then laying from top to bottom in the relay protection screen. This method will cause the friction between the control cable and the window sill of the building not only to cause damage to the cable protective layer, but also to cause damage to the aluminum alloy window frame. Simultaneously, if the staff accidentally drops their hands, the cable will slide from upstairs due to gravity, which may injure the staff on the ground in the lower part, which not only affects safe production but also affects construction efficiency, so there is a big defect.

Patent application number 201010579983.0 discloses a control cable laying device, which uses a thread pair and a compression pad to fix the beam under the window frame. The tightening of the compression pad in this way is likely to cause damage to the wall. Swinging the roller is easy to cause insufficient force.

Contents of the invention

In order to overcome the deficiencies of the prior art, the object of the present invention is to provide an auxiliary device for laying control cables, which prevents the falling cables from hitting people on the ground and does not cause damage to the wall.

To achieve the above object, the present invention is achieved through the following technical solutions:

An auxiliary device for laying control cables, including a bracket, a hydraulic cylinder, a pressing pad, a fixed wheel, a pressing pad, a support frame, a shaft, a limit mechanism, and a beam. One side of the bracket is fixedly connected to the beam, and the top end of the other side is fixedly connected. A support frame, a connecting shaft is fixed on the support frame, a fixed wheel is arranged on the shaft, the hydraulic cylinder is fixed on the beam, and a pressure pad is fixed at the output end of the hydraulic cylinder. The limit mechanism includes a connecting rod, a fixed rod, and a limit wheel , anti-skid piece, spring, one end of the fixed rod is fixedly connected with the shaft, the other end is hinged with the middle of the connecting rod, one end of the connecting rod is connected with the limit wheel, the other end is fixedly connected with the anti-skid piece, one end of the spring is fixedly connected with the limit wheel, and the other end fixed on the support frame.

A sawtooth structure is provided on the outer wall of the anti-skid member.

The spacer wheel is a pulley.

Compared with prior art, the beneficial effect of the present invention is:

The structure is simple, the operation is convenient, the construction safety is ensured, and the building will not be damaged.

Detailed ways

The present invention will be described in detail below in conjunction with the accompanying drawings, but it should be pointed out that the implementation of the present invention is not limited to the following embodiments.

See Figure 1-Figure 5, control cable laying auxiliary device, including bracket 1, hydraulic cylinder 3, pressing pad 4, fixed wheel 2, pressing pad 4, support frame 5, shaft 10, limit mechanism, beam 13, bracket 1. One side is fixedly connected with a crossbeam 13, and the top of the other side is fixedly connected with a support frame 5. The support frame 5 is fixedly connected with a shaft 10. The shaft 10 is provided with a fixed wheel 2. The hydraulic cylinder 3 is fixed on the crossbeam 13, and the hydraulic cylinder 3 outputs end is fixed with pressing pad 4, and described position-limiting mechanism comprises connecting rod 6, fixed rod 7, limit wheel 8, antiskid member 12, spring 9, and one end of fixed rod 7 is fixedly connected with axle 10, and the other end is connected with connecting rod The middle part of 6 is hinged, one end of the connecting rod 6 is connected with the limit wheel 8, and the other end is fixedly connected with the anti-skid member 12, one end of the spring 9 is fixedly connected with the limit wheel 8, and the other end is fixed on the support frame 5. The outer wall of the anti-skid member 12 is provided with sawtooth structures. Described spacer wheel 8 is a pulley. The fixed wheel 2 has a smooth surface, is fixed on the shaft 10, and has no relative movement with the shaft 10; Four fixed wheels 2 are fixed on the support 1, and each fixed wheel 2 is equipped with a limit mechanism.

During use, the support 1 is erected on the window frame, adjusted by the hydraulic cylinder 3, so that the pressing pad 4 is pressed against the wall at the bottom of the window frame, so that the whole device is fixed firmly, and then the cable 11 is connected from the fixed wheel 2 to the anti-skid 12, go around the fixed wheel 2 and pass between the limit wheel 8 and the fixed wheel 2, and then lay the cable 11. Once the cable 11 falls off, the limit wheel 8 will drop under the action of the spring 9 and gravity, driving the connection One end of the anti-skid piece 12 of the bar 6 rises, and the anti-skid piece 12 leans against the fixed wheel 2. Since the anti-skid piece 12 fixed on the connecting rod 6 is provided with a sawtooth structure, the cable 11 cannot continue to slide down, thereby ensuring the safety of the construction. Fixing the support 1 in a hydraulic manner is convenient and quick, and will not damage the wall, which meets the clamping requirements of different walls. The principle of leverage is used to realize the dual functions of judging cable slipping and preventing further slipping.
