Description

[Detailed description of the invention] [Industrial application field] The present invention includes a structure in which a support is erected in the driving section, a sunshade frame is connected and fixed to the upper end of the support, and a holo is detachably attached to the sunshade frame. Regarding a certain backbone.

[Conventional technology]

Conventionally, as shown in Fig. 5, a head guard made of cushioning material such as sponge has been used to prevent the operator from hitting his head on the connecting part 11 between the upper end of the column and the awning frame when driving on rough terrain or during extreme excavation work. 12' was directly adhered to the connecting portion 11.

[Problem that the invention attempts to solve]

However, since the head guard 12' cannot be removed from the connecting part 11, if the sunshade is removed from the sunshade frame and left for a long time, the head guard 12'
2' had poor weather resistance, so there was a risk of damage.

An object of the present invention is to ensure that the head guard can be removed from the connecting portion when removing the holo from the sunshade frame.

[Means for solving problems]

The characteristic structure of the solar awning of the present invention is that one end of the head guard that covers the connection between the upper end of the column and the awning frame is attached to the hollow, and a string member for fixing to the column is attached to the other end. The effects are as follows.

[Effect]

In other words, when removing the holo from the sunshade frame, simply remove the fixing string member at the other end of the head guard from the support, and since one end of the head guard is attached to the holo, the head guard can be securely removed from the connecting part along with the holo. .

[Effect of idea]

Therefore, even when the backhoe must be removed from the sunshade frame and left for a long period of time, such as during transport or when the backhoe is not in use, the head guard can be removed without forgetting, and damage to the head guard can be reliably avoided. , the safety function of the head guard for the operator can be maintained satisfactorily over a long period of time.

Furthermore, since the head guard can be removed together with the holo by simply removing the fixing string member from the support, the work for attaching and detaching can be made extremely simple and easy.

[Example] Next, an example of the present invention will be described based on the drawings.

As shown in FIG. 3, a swivel base 2 is attached to a machine body equipped with a crawler traveling device 1 so as to be freely driven and rotated around the vertical axis, and a backhoe device that can freely swing up and down and bend and extend is attached to the swivel base 2. 3. Bonnet 4
The driving part 6 is provided with a driving part covered with a movable part covered with a sunshade 5 and an operating part 6 having a sunshade 5 disposed above and an operating lever 10 disposed at the lower front part, and constitutes a backhoe mainly used for ground excavation work.

To construct the awning 5, as shown in FIGS. 1 and 2, a pair of columns 7 are provided upright on both left and right sides of the driving section 6, and a flange portion 7A formed at the upper end of the columns 7 has a flange portion 7A. Horizontal plate portions 8A of a metal sunshade frame 8 are placed and connected and fixed to each other with bolts and nuts, thereby integrating the pillar 7 and the sunshade frame 8.

Then, in order to removably attach the holo 9 to the sunshade frame 8 and cover the connecting part 11 consisting of the flange part 7A and the horizontal plate part 8A with a bag-shaped head guard 12 containing a cushioning material such as a sponge inside, One end of the head guard 12 is attached to the holo 9, and a pair of fixing strings 13 are attached to the other end to wrap around and tie the support 7.

The operating lever 10 is configured so that the operating lever 10, which projects upward, can be divided into upper and lower halves, as shown in FIG. 4A, in order to stack the entire backhoe in two stages during transportation.

In other words, the horn switch 15 is attached to the grip 14.
built-in, and the electrical wiring 16 of the switch 15,
It passes through the inside of the operation lever 10 which is divided into upper and lower halves, and is formed with a female thread 17 at the connection part of the upper and lower divided operation levers 10A and 10B, respectively, and a male screw 18 is formed on both sides of both the female threads 17, 17. They are screwed together via a certain turnbuckle 19, and both the upper and lower threaded portions are prevented from loosening with lock nuts 20, respectively.By connecting the upper and lower split operation levers 10A and 10B through the turnbuckle 19 in this way, the lever 10 The electrical wiring 16 inside is not twisted, and damage to the electrical system can be avoided. When transporting, the operating lever 10 is divided into upper and lower halves as shown in FIG. 4B, and is tied and fixed in the folded state.

[Another example]

Instead of the string 13, a band-like member or a pair of magic fasteners or the like may be used, and these are collectively referred to as a string member.

Instead of the female thread 17, a male thread may be formed at the connecting portion of the upper and lower split operation levers 10A and 10B, and a female thread may be formed on the turnbuckle 19.
