Abstract

The utility model discloses a tree jacking device, belongs to the technical field of greening appliances, and aims to overcome the defects that upward pulling component force is generated to a trunk and friction force harmful to the cortex is generated to the bark in the conventional frequently-used methods of jacking the tree through a lifting jack. The tree jacking device comprises a lifting jack, a ground frame and a rotating frame, wherein the ground frame is provided with a slit front end and is n-shaped; the left rods as well as the right rods of the ground frame and the rotating frame are hinged in a same axis center line at the front ends respectively; a tree support is mounted at the upper part of a cross rod of the rotating frame; the lifting jack is arranged between a cross rod of the ground frame and the cross rod of the rotating frame; the base and the jacking rod head of the lifting jack are hinged to the cross rod of the ground frame and the cross rod of the rotating frame respectively. The tree jacking device is suitable for righting a lodging tree.

Description

Play tree device

Technical field

The utility model relates to a kind of greening implement technology, particularly relates to a kind of tree device that rises.

Background technology

In order to afforest our motherland, beautify the environment of our life, many cities of China, in carrying out house and urban construction on a large scale, also synchronously carrying out going deep into the greening work in each corner, not only in road, roadside, the other grass of planting is planted trees, and in people's residential quarter, also accomplishes dense, the timbered degree of flowers and plants.But often " the road to happiness is strewn with setbacks ", our greening work also will run into many setbacks, such as, in the southern coastal cities of China, often have typhoon and patronize.After typhoon, a lot of trees can be blown down askew, and wherein having a lot of trees is all the large tree of cultivating for many years through people.Because having, tree stretches the dark root system of pricking in earth to four sides; no matter blown down or blow askew tree, some root system is tied in mud still, as long as we can protect this part intact root system and no longer be hurt; after tree righting, training is upper new native again, trees can be brought back to life.At present, people are in the time propping up tree, and majority will be used jack, and first treetop is played and approached the position vertical with ground, and then tree is just drawn with rope in another direction, the upper soil of training.In process treetop being risen with jack, have do not allow us to ignore at 2: the one, the push rod of jack and tree bar have an angle, the top power of push rod will produce a component upwards, this component can upwards pull out tree, can destroy on the contrary and remain contacting of intact part root system and earth; The 2nd, the contact site of mandril of lifting jack head and tree bar can produce larger frictional force, even the upper bed course of pad, this frictional force still can damage bark, and surviving of trees had a negative impact.

Summary of the invention

The purpose of this utility model is to provide a kind of tree device that rises, and overcomes that conventional at present method treetop being risen with jack is existing can produce the component upwards pulling up and the deficiency that can produce the frictional force harmful to cortex to bark to tree bar.

The utility model is achieved by following technical proposals.

The utility model comprises jack, is provided with front end jag and is ground frame and the pivoted frame of " door " shape, and the left side bar of described ground frame and the left side bar of described pivoted frame, the right bar of described ground frame and the right bar of described pivoted frame are hinged with same shaft centre line at front end respectively; Tree holder is housed above the cross bar of described pivoted frame, between the cross bar of described ground frame and the cross bar of described pivoted frame, described jack is housed, base, the push rod head of described jack are hinged with the cross bar of the cross bar of described ground frame, described pivoted frame respectively.Described jack is lifting gear conventional in greening maintenance work, and in the technical program, conduct provides the parts of power.So causing, described ground frame and described pivoted frame to be designed to " door " shape, can allow like this front end of described ground frame and described pivoted frame insert from the both sides of tree, make the center of rotation axis of pin joint and the lower end of tree bar of described ground frame and described pivoted frame front end approaching as far as possible, in the time playing tree, set up with the form of rotating with tree bar by described pivoted frame, the displacement that the root of tree can not produce horizontal direction, the root system that trees are still pricked in earth deeply also just can not sustain damage.In the time that described jack carries out jacking, described pivoted frame take with the line of centres of the pin joint of described ground frame as rotary middle spindle rotates, its cross bar raises gradually, hold tree bar by described tree holder immediately, allow tree bar substantially rotate and to establish as center of rotation take lower end.

Known according to mechanical analysis, the component that the non-described pivoted frame that described jack produces in jacking process rises direction is born with the form of tension by the left and right side rod of described pivoted frame, can not impute to trees, and trees are without the worry being pulled up.Meanwhile, between described tree holder and tree bar, there is no relative sliding motion, can not damage because of friction so contact the position of described tree holder on tree bar yet.

In the utility model, although there is no relative sliding motion between described tree holder and tree bar, on contact-making surface, there is larger pressure, in order to reduce pressure, reduce the injury of pressure to tree bar cortex, on the support of described tree holder, cushion is housed.In addition, described jack is in jacking process, and described ground frame can be subject to the component that a horizontal direction is drawn back, and in order not make described ground frame retreat, at least one anti-slop serrations is housed below described ground frame.

Against existing technologies, the beneficial effects of the utility model are:

In the righting process of the trees that lodge, significantly reduce to trees are still stayed the destruction of root system in soil and earth conjugation and avoid the frictionally damage to bark.

Accompanying drawing explanation

Fig. 1 is structural representation of the present utility model, and the A that Fig. 2 is Fig. 1 is to view.In figure: 1, jack, 2, frame, 3, pivoted frame, 4, tree holder, 5, cushion, 6, anti-slop serrations.

Embodiment

Below in conjunction with accompanying drawing and embodiment, the utility model will be further described.

In order to make the convenience of the utility model carrying, have the assembling between multiple parts is by hinged mode simultaneously, so: between ground frame 2 and pivoted frame 3, between tree holder 4 and pivoted frame 3, between jack 1 and ground frame 2, pivoted frame 3, all can connect with bolt, nut, so not only solid and reliable but also be convenient to handling.Between two side rods of ground frame 2, pivoted frame 3 to open span several from making different spacing, to adapt to the trees that different bars are thick.

Claims

1. one kind is played tree device, comprise jack, it is characterized in that, be provided with front end jag and be ground frame and the pivoted frame of " door " shape, the left side bar of described ground frame and the left side bar of described pivoted frame, the right bar of described ground frame and the right bar of described pivoted frame are hinged with same shaft centre line at front end respectively; Tree holder is housed above the cross bar of described pivoted frame, between the cross bar of described ground frame and the cross bar of described pivoted frame, described jack is housed, base, the push rod head of described jack are hinged with the cross bar of the cross bar of described ground frame, described pivoted frame respectively.

2. one according to claim 1 plays tree device, it is characterized in that, on the support of described tree holder, cushion is housed.
