Description
Technical Field
The invention relates to piling machinery, in particular to a temporary auxiliary device for an external supporting leg of the piling machinery.
Background
With the development of urban modern construction, the height of a building group and the depth of underground building engineering are continuously updated, and pile foundation engineering breaks through in a deeper direction. Under the condition that other performances of a plurality of existing pile machine equipment are met, the height of the upright column is not enough, so that the engineering construction requirements of increasing and increasing extra depth cannot be met. In order to save cost and reduce equipment investment of construction enterprises, a temporary auxiliary device for externally connecting supporting legs of piling machinery is researched, existing fixed assets are stocked, and sustainable development of enterprises is realized.
The vertical column of the pile machine is in the working condition of the largest overturning moment of the equipment. When the upright post is connected, in order to balance the overturning moment and the balance moment when the pile machine lifts the upright post, the overturning moment when the pile machine lifts the upright post can be reduced by adding a balance weight or large-scale hoisting equipment, and the like, so that the aim of lifting the upright post is fulfilled. However, there are drawbacks to using this approach: site limitations, equipment structure limitations, etc.; the transportation safety is reduced; the economic benefit is not good; after the equipment finishes the stand column to finish the starting, a large balance moment is not needed in the construction process, and even the added balance weight can cause the equipment to overturn reversely. Therefore, in order to solve the problem, the overturning moment of the pile machine is reduced under the condition that other equipment and counter weights are not required to be added, a mode of externally connecting supporting legs can be adopted, temporary assistance is carried out when the pile machine is used for lengthening and lifting the upright post, and the supporting point of the equipment is moved forwards, so that the construction capacity of the equipment is increased, and the construction requirement is met.
Disclosure of Invention
The invention aims to provide a temporary auxiliary device for an external supporting leg of a piling machine, which increases the anti-overturning moment of equipment when the equipment rises and falls an upright column by advancing a supporting point, thereby expanding the construction capacity of the equipment and realizing construction requirements. And as temporary auxiliary support, only use when the stake machine rises and falls the stand, follow-up construction need not under the condition of very big counter torque, can load and unload in a flexible way, solve the technical problem of the current equipment extra-deep construction.
In order to achieve the purpose, the invention provides the following technical scheme:
a temporary auxiliary device for an external supporting leg of a piling machine comprises an extension supporting leg and a connecting hinged support, wherein the extension supporting leg is hinged to the piling machine through the connecting hinged support; the extension landing leg is truss-like or real abdomen formula steel member, adopts triangle stable structure landing leg, can satisfy the structure atress, antidumping stability when increasing piling machinery rising and falling column frame.
Furthermore, two groups of connecting hinged supports are arranged, one end of each group is welded on the base plate of the piling machinery base, the other end of each group is welded with the extension supporting leg, and the extension supporting leg and the piling machinery are connected through the two groups of connecting hinged supports through bolts and nuts so as to be convenient to assemble and disassemble.
Furthermore, the bottom of the extension supporting leg is padded with a base plate for reducing the concentrated stress and the diffusion ratio pressure of the foundation and improving the bearing capacity.
The invention has the beneficial effects that:
through the external temporary auxiliary device of landing leg of piling machinery, can make its strong point antedisplacement when the stake machine rises and falls the stand, increase the antidumping moment of equipment temporarily, realize lengthening the stand and need not to increase the counter weight alright accomplish rising and falling of stake machine stand, enlarge the actual construction ability of piling equipment, satisfy the construction demand.

Detailed Description
In order to make the objects, technical solutions and advantages of the present invention more apparent, the present invention is described in further detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative of the invention and are not intended to limit the invention.
As shown in fig. 1 and 2, the temporary auxiliary device for the external support leg of the piling machinery comprises an extension support leg 1, a connecting hinge base 2, a backing plate 3 and the like.
The expansion supporting leg 1 is a truss type or solid web type steel member, adopts a simple triangular stable structure supporting leg, and can meet the structural stress and ensure the anti-overturning stability when the equipment is additionally provided with a pulling frame.
The two groups of connecting hinged supports 2 are arranged together, one end of each group is welded on the base plate of the piling machinery, the other end of each group is welded with the extension supporting leg 1, and the extension supporting leg 1 is mechanically connected with the piling machinery through bolts and nuts by the two groups of connecting hinged supports 2, so that the assembling and disassembling are convenient.
The base plate 3 is padded at the bottom of the extension supporting leg 1, so that the concentrated stress and the diffusion specific pressure of the foundation are reduced, and the bearing capacity is improved.
The invention has the following beneficial effects in specific implementation: as shown in fig. 3 and 4, the front side of the body of the pile machine is provided with a brace, and the self-stability when the pillar is attached and detached can be obtained:
after the upright post is lengthened, the temporary auxiliary device for the external supporting leg of the piling machinery is installed by equipment
Can ensure

the weight of the vehicle body part of the original pile machine is in unit N;
a、b——
and
arm of force of (d), in units of m;
a′、b′——
and
arm of force of (d), in units of m;
l-the length of the pile machine upright column connection height, unit m;
m is the overturning moment of the upright column, and the unit is N.m;
after the external temporary auxiliary device for the supporting leg of the piling machine is installed on an original pile machine, the stability of the equipment after the upright post is lengthened when the upright post rises and falls can be ensured.
According to the improvement of an example, the temporary auxiliary device for the external supporting leg of the piling machine is used, and the pile machine is used for lengthening the upright column, so that 20% of the capacity of the plateau equipment can be effectively improved, and the construction problem of the ultra-deep foundation engineering is solved.
In conclusion, in the concrete implementation of the invention, the extension supporting leg 1 is connected with the piling machinery vehicle body through the two groups of connecting hinged supports 2, the triangular stable structure is used for replacing the common quadrilateral supporting leg, and the base plate 3 is arranged at the bottom of the extension supporting leg 1, so that the concentrated stress of the foundation is reduced. The external landing leg temporary auxiliary device of stake machine equipment fixing can increase the anti-overturning moment of equipment temporarily, prevents that the stake machine from connecing long stand back because of the stand that plays to fall produces the unstability slope, realizes the purpose of enlarging stake machine actual construction ability, and nimble loading and unloading after the stand completion that rises and falls, does not receive the construction site restriction, does not influence follow-up construction.
