Description

[Detailed description of the invention] [Field of industrial application] This invention is a jacking base that is used to clean and repair a jacking base, which is one of the temporary materials used at construction sites, so that it can be used again after it has been used. Regarding maintenance machines.

[Conventional technology and its problems]

Conventionally, this type of jack-based maintenance machine has not been provided. Scraping of concrete and spray paint adhering to the jack base was done by hand with a wire brush, and the arm was also rotated by hand, and curved bottom plates were repaired by hitting them by hand with a sledgehammer. It is something that For this reason, maintenance work on the jack base is extremely inefficient, and repairs using a sledgehammer in particular are dangerous, and there is a risk of damage to the welded portion between the screw rod and the bottom plate of the jack base.

The present invention was proposed with the aim of solving such problems.

[Means for solving problems]

The structure of the present invention that achieves the above object will be explained based on the illustrated embodiments as follows.

That is, the jack-based maintenance machine of this invention comprises a machine frame a, a cleaning device b and a repair device c.

The cleaning device b is the bottom plate 10 of the jack base e.
a jack base erecting support d that receives the jack base e and supports the jack base e in an upright manner;
The arm 12 is engaged with the screw rod 11.
It consists of an arm rotating body f that is forced to spiral around the arm.

The jack base erecting support d is connected to a vertical movement mechanism h, and the arm rotating body f is connected to an electric motor g.

The repair device c includes a jack base upright support i for mounting the bottom plate 10 of the jack base e and supporting the jack base e upside down, and a fluid pressure cylinder j constructed above the jack base inverted support stand i.
and a hammer 28 attached to the tip of the piston rod 27 of the cylinder j.

The fluid pressure cylinder j is connected to an electric fluid pressure drive mechanism k.

[Effect]

Therefore, to perform cleaning, the bottom plate 10 of the jack base e is erected and supported on the jack base erecting support d, and then the jack base e is raised by the vertical movement mechanism h. When the arm 12 is engaged with the arm rotating body f, the arm rotating body f is rotated by the electric motor g, and the arm 12 is connected to the screw rod 1.
When rotated around 1 and moved up and down as appropriate, the screw rod 11
Surrounding concrete, etc., including inside the screw grooves, can be removed.

In addition, in order to repair the curved bottom plate 10,
The jack base e is supported with its bottom plate 10 upside down on the jack base inverted support stand i,
Fluid pressure cylinder j by electric fluid pressure drive mechanism k
is activated, and the bottom plate 10 can be appropriately hammered and shaped from the back side with the hammer 28.

〔Example〕

The illustrated embodiment will be described in detail below.

A is a machine frame made by horizontally suspending a beam 4 between the upper ends of pillars 2 and 3 established on the left and right sides of the machine frame 1, and this machine frame a
is equipped with a cleaning device b and a repair device c.

The configuration of Keren device b is as follows.

Reference numeral d denotes a jack base erecting support, which is fitted into a guide frame 5 protruding from the lower front surface of the column 2 so as to be movable up and down, and a thin fixed frame 7 with an opening 6 at least on the front surface is placed on the upper end of the guide frame 5. In addition to being fixed, a recess 9 that is continuous with the opening 6 is provided in the top plate 8 of the thin fixed frame 7.

Reference numeral e designates a jack base in which an arm 12 is screwed into a screw rod 11 established and fixed at the center of the bottom plate 10. To do this, the screw rod 11 is aligned with the recess 9, and the bottom plate 10 is pushed through the opening 6, thereby raising and supporting the jack base e on the jack base erecting support d.

f is a mounting frame 1 protruding from the upper front surface of the pillar material 2;
A cylindrical arm rotating body suspended from the lower end of a rotating shaft 14 supported on has been done. g is an electric motor installed on the back of the upper part of pillar material 2;
It is connected to the rotating shaft 14 via a required speed reduction mechanism, and the arm rotating body f is connected to the rotating shaft 14 by this electric motor g.
can be rotated.

h is a lever 1 whose tip is pivotally connected to a link 16 pivotally supported on the lower front surface of the jack base erecting support d;
This is a vertical movement mechanism formed by connecting a foot pedal 18 to the base end of 7 through a chain 19. By depressing the pedal 18, the lever 17 rotates around its fulcrum 20, and the jack base erecting support d can be moved upward, thereby lifting the jack base e, which is supported upright, onto its arm 12. can be raised to a desired height where it engages the longitudinal groove 15.

In the above-mentioned engaged state, if the arm rotating body f is rotated in a desired direction by the electric motor g and the arm 12 is forcibly screwed up and down along the screw rod 11, concrete adhering to the circumferential surface of the screw rod 11 can be removed. etc. will be automatically removed. Note that g′ is the electric motor operation panel.

Next, the repair device c will be described.

i is a jack-based inverted support stand, which has left and right reinforcing pieces 23, 23' installed between the horizontal main plate 21 and the horizontal sub-plate 22, which are suspended horizontally between the central parts of the pillars 2 and 3; Recesses 24 and 25 are provided in the front surfaces of the horizontal main plate 21 and the sub-plate 22 at a central position between the left and right reinforcing pieces 23 and 23'.

The jack base e is supported upside down on the jack base inverted support stand i by inserting the screw rods 11 into the recesses 24 and 25 and placing the bottom plate 10 on the horizontal main plate 21.

j is a hydraulic or pneumatic hydraulic cylinder installed above the inverted jack base i,
It is the support plate 2 that is horizontally suspended above the horizontal main plate 21.
The piston rod 27 is installed vertically between the piston rod 6 and the beam 4, and a hammer 28 is attached to the tip of the piston rod 27. K is an electric fluid pressure drive mechanism such as hydraulic or pneumatic pressure, and the drive mechanism k is appropriately operated from the operation panel 29, and the bottom plate 10 of the jack base e is struck with a hammer 28 to repair its curved deformation.

[Effect of idea]

As is clear from the above, according to the present invention, the bottom plate of the jack base for cleaning is erected and supported on the jack base erecting support base, and then the jack base erecting support base is raised by the vertical movement mechanism. When the arm of the jack base is engaged with the arm rotating body, the arm rotating body is rotated by an electric motor, and the arm is rotated around the screw rod and moved up and down as appropriate, thereby removing the surrounding concrete, etc., including the inside of the screw groove of the screw rod. Can be removed.

In addition, in order to repair a curved and deformed bottom plate, the bottom plate of the jack base is supported upside down on an inverted jack base support, and a hydraulic cylinder is actuated by an electric fluid pressure drive mechanism, and the hammer is used to repair the bottom plate. It can be repaired by hitting it from the back side as appropriate.

In other words, according to the present invention, the cleaning and repair of the jack base, which was conventionally done manually using a wire brush or a sledgehammer, can be carried out automatically, safely and reliably, and the work efficiency per unit time is significantly improved. It is possible.
