Efficient and convenient cement concrete pole correcting equipment

Abstract

The invention discloses a high-efficiency and convenient positive pole equipment for cement concrete poles, which comprises a horizontally arranged base, a second limit device and a first limit device at both ends of the base, and hinged joints in the support section of the base. A swing tube that can swing back and forth. A support device is inserted into the swing tube. The support device is locked together with the middle and upper section of the cement concrete rod through a hinged locking device that swings up and down. The power input end of the support device passes through a flexible transmission hose. It is connected with the transmission of the power unit, a handle is also fixed on the support seat, and an outwardly expanding protective cover is fixed at the inner end of the handle. The advantage is that it can quickly excavate the soil and rocks on the right side of the cement concrete pole, prevent dust from invading, and can quickly straighten the cement concrete pole, saving time and effort, fixed firmly, small in size, easy to carry, one person can independently straighten the cement concrete pole, and the straightening efficiency is high , and can prevent the cement concrete rod from breaking.

Description

technical field [0001] The invention relates to electric power maintenance equipment, in particular to an efficient and convenient cement concrete pole positive pole equipment. Background technique [0002] Low-voltage overhead lines are lines used for residents' living and agricultural production. Most of the low-voltage overhead lines are supported and erected by cement concrete poles. When the cement concrete pole is erected, it is generally hoisted and righted by a crane, and the erection is very simple. Because the soil is soft when the cement concrete pole is installed for the first time, the cement concrete pole during erection is often inclined, so that the crane can only erect the second cement concrete pole after the completion of the erection of one concrete concrete pole. The erection efficiency is low. For example, the pole centralizer with the Chinese patent number of 201320216893.4 is designed for hoisting cement concrete poles. After the cement concrete po...

Problems solved by technology

If the cement concrete pole tilts during this process, it will be very difficult to straighten it. The reasons are as follows: when the cement concrete pole is straightened, it must occupy the ground space on the right side. Then, 1. If the earth and rocks in this space are not removed , then the earth and stone must be strongly squeezed, and the external force required is extremely large. Generally, construction machinery, such as cranes, bulldozers, etc., must be used. Even if construction machinery is used for strong straightening, there is also the disadvantage of easily pushing and breaking the cement concrete rod; 2. If To clear the soil and rocks in this space, if it is done manually with a shovel, firstly, the soil and rocks on the surface are relatively hard, and it is difficult to excavate with a shovel. That is to say, the space on the right side of the excavated cement concrete pole is a conical shape with a large upper end and a smaller lower end, so it is time-consuming, labor-intensive, and inefficient. If it is completed by construction machinery such as an excavator, there will be problems of terrain and traffic restrictions. and rectify the problem of high cost

The invention patents with Chinese patent numbers 201220200863.X and 201220222955.8 disclose two positive rod devices. These positive rod devices use the jacking force of the hydraulic lifting device (jack) to carry out strong righting and have a certain righting effect, but there are the following Disadvantages: 1. It does not have the function of cleaning up the soil and rocks on the side of the cement concrete pole. It has a certain effect on the new cement concrete poles with a stable structure that are newly put into use by pulling and pulling hard to straighten the cement concrete poles. For the old cement concrete poles for many years, it is easy to break the cement concrete poles during the righting process; 2, because the cement concrete poles are generally erected in the wilderness, it is not only difficult for large-scale construction machinery to enter, but the cost of righting is also greatly increased. The soil and rock excavation work around the concrete pole is generally done manually by several workers in turn using tools such as shovels and picks. The self-weight of the cement concrete pole is much greater than the weight of the straight nail at the bottom of the jack, and the fixing effect of the cement concrete pole submerged in the underground part is much greater than that of the straight nail submerged in the underground part, and the soil becomes hard. If the jack is used for strong righting, only the bottom of the jack will slip with the ground and cause the righting to fail; 4. The two positive rod devices used are locked with the concrete rod through the hoop (clamp), and the force is applied to the hoop (clip) It can be seen from the analysis that the force of the hoop (clip) by the jack can be divided into the upward force along the cement concrete rod and the force in the righting direction of the cement concrete rod, and the force in the righting direction of the cement concrete rod has the effect of righting the cement concrete rod. However, since the cement concrete rods are all tapered columns with thinner upper ends and thicker lower ends, the upward force along the cement concrete rods will push the hoop (clip) to the thinner end of the cement concrete rods. If the force is greater than the frictional force between the inner wall of the hoop (clip) and the outer wall of the concrete pole, the hoop (clip) will inevitably slip upward along the concrete pole, resulting in failure of righting
