Miniature piling machine

Abstract

The invention relates to a minitype piling device, which comprises a base, a frame, a windlass and a pile hammer, wherein a steel wire rope of the windlass is connected with the pile hammer through a guiding pulley on the upper part of the frame, the frame is lower than 2.20 m, and a pile hammer guiding mechanism is arranged in front of the frame. The pile hammer guiding mechanism comprises an overground guide rod arranged on the upper part of the base and an underground guide rod arranged on the lower part of the base, a hanging ring is arranged on the top of the pile hammer, a pothook provided with a long control handle is matched with the hanging ring, and the end part of the steel wire rope of the windlass is hinged with the middle part of the pothook body. Aiming at the base sedimentation problem of silt groundsill or soft soil groundsill equipment of transformer substations, the minitype piling device is developed under the requirements that limited safety height is 2.2 m and the power is not cut off, and breaks through a forbidden zone that piling is difficult in a running transformer substation in a special construction environment when basic reinforcement is carried out. The minitype piling device is easy to operate, and has small volume and favorable adaptability to the reinforcement and correction of the base sedimentation of industrial production devices.

Description

technical field [0001] The invention relates to a pile foundation construction equipment, in particular to a miniature pile driver. Background technique [0002] In the coastal areas of our country, the rapid economic development requires a large number of new substations, some of which are inevitably built on weak foundations. Once errors occur in the exploration, design, construction and other links of substations on coastal sea silt and lake silt foundations, it may cause substation equipment foundation settlement, which will directly affect the safe operation of power facilities. Due to the long period of development of foundation settlement, such accidents are often discovered after the equipment is put into operation, and the reinforcement of the settlement foundation under the condition of high-voltage electrified operation will face great risks. The existing reinforcement methods and mechanical equipment are all It cannot meet the technical requirements of working i...

AI Technical Summary

Problems solved by technology

[0006] (2) Various existing construction machines are restricted by the safe construction distance and cannot enter the site for construction;

[0008] (4) Due to the light weight of the equipment and foundation, the reaction force of the reinforced foundation cannot be used during reinforcement
