Description

[Detailed description of the invention] (a) Industrial application field The present invention relates to a canopy support structure in a boxhoe, etc.

(b) Prior Art Conventionally, one type of driver's section for a backhoe has two canopy pillars erected in a forward-leaning position at the rear of the driver's section, and the rear end of a canopy is attached to the upper ends of the canopy pillars in a cantilever-like manner, covering the driver's section.

(c) Problems to be solved by the invention By the way, when transporting such a backhoe to a work site on a truck, or when disassembling the backhoe for repair and maintenance, it is necessary to remove the canopy together with the canopy support. .

However, since the canopy support is tilted forward and supports the canopy in the form of a cantilever, when removing the base end of the canopy support from the fixed part at the rear of the driver's unit by loosening the mounting bolts, etc., the canopy support supports the canopy in a forward leaning position. This causes the person to fall forward, and as a result,
It is impossible for one person to carry out the work of removing such a canopy, etc., and the same applies to the work of installing it. Therefore, the work of installing and removing the canopy etc. requires a great deal of effort and becomes a complicated work.

An object of the present invention is to provide a canopy support structure for a backhoe or the like that can solve the above-mentioned problems.

(d) Means for solving the problem The present invention involves installing a canopy support at the rear of the driving section, attaching a canopy that covers the top of the driving section via a rectangular frame to the upper end of the canopy support, and A part of the components of the canopy is positioned in the front-rear direction to form a movable component, and the movable component is moved downward with the front end of the canopy as the center of rotation, so that the movable component is rotated approximately vertically at the front of the driving section. A canopy support for a backhoe, etc., characterized in that the canopy is pivoted to a canopy support position, the pivoting end of which is detachably connected to a fixed part in front of the driving part, and the canopy is supported by a movable component. It is intended to provide structure.

(E) Function During normal operation of the above-mentioned box hoe, the movable components are in the canopy configuration position and are used only to support the canopy cloth, etc. Also, since they are not located in front of the driving section, they are not located in front of the driver's vehicle. It does not obstruct your field of vision.

On the other hand, when removing the canopy, etc., first rotate the movable component around the front end of the roof to the canopy support position located in front of the driver's unit, and then detachably connect its lower end to the fixed part in front of the driver's unit. do.

Then, by loosening the mounting bolts, etc., the base end of the canopy support is removed from the fixed part behind the driver. In such removal, since the front end of the canopy is supported by the movable component, it is possible to reliably prevent the canopy and the canopy support from falling forward.

After the proximal end of the canopy post has been completely removed as described above, the lower end of the movable component can be removed from the fixed part and the entire canopy can be lifted and removed from the driver part.

In addition, it is also possible to operate with the movable component connected to the fixed part in front of the driving part, in this case,
The movable component can be used as a guard frame for the driver.

(F) Effects With the configuration described above, the present invention has the following effects.

When removing the canopy, since the front end of the canopy is supported by a movable component, it is possible to reliably prevent the canopy and canopy support from falling forward, making subsequent removal of the canopy and canopy support easy. can be done.

During normal operation, the movable component can be used as a component of the canopy, and loosening of the canopy cloth, etc. can be effectively prevented.

During normal driving, the movable component is in the canopy configuration position, so it does not obstruct the driver's forward vision.

When operating with the movable component connected to the fixed part in front of the driver, the movable component can also be used as a guard frame for the driver.

(g) Examples The present invention will be specifically described below based on examples shown in the attached drawings.

First, the overall configuration of a backhoe equipped with a canopy support structure according to the present invention will be described.

In Fig. 1, A is a backhoe, and the backhoe A has a swing base 2 installed between crawler-type left and right running parts 1 and 1, and a swing base 3 is mounted on the swing base 2 so as to be freely swingable. It is location.

Further, a driving section 5 including a canopy 4 is provided on the front upper surface of the swivel base 3, and a prime mover section 6 is provided at the rear thereof.

Further, at the front end of the swivel base 3, a working machine section 8, which includes, for example, an excavating bucket cart 8, etc., is attached to the front end of the swivel base 3 via a mounting bracket 7 which is rotatable left and right, so as to be swingable up and down.

Further, the driving unit 5 is provided with an operating column 9 at the front thereof, and the operating column 9 has an operating lever 10 protruding from its upper surface, and furthermore, a front handrail 11 is arranged in front of the operating column 9. It is set up. on the other hand,
The driver section 5 is provided with a seat 12 at the rear thereof.

The present invention is characterized by a canopy support structure that allows the canopy 4 to be easily and reliably removed in the basic configuration of the above-mentioned backhoe A, etc., and does not impede the function of the canopy 4 during normal operation.

Hereinafter, such a canopy support structure will be explained with reference to FIGS. 2 and 3.

As shown in the figure, one end of the canopy support 13 is attached to the front end of the prime mover section 6, which is a fixed part, with a support mounting bolt 1.
4 is firmly fixed.

The canopy support 13 is erected with its upper end inclined forward, and the rear part of the canopy 4 is integrally and fixedly connected to the upper end.

As shown in the figure, the canopy 4 has a rectangular frame 4a.
A canopy cloth (not shown) such as a canvas is mounted on the upper surface of the frame, which is constructed by horizontally suspending a pair of fixed structural members 4b in the width direction inside the frame and horizontally suspending a pair of movable structural members 4c in the front-rear direction. ).

In this configuration, the fixed component 4b is connected and fixed to a bracket 15 provided at the upper end of the canopy support 13.

On the other hand, the movable component 4c has its base end rotatably supported on the rectangular frame body 4a on the front end side of the canopy 4 via the rotation sleeve 16, and its tip end when the backhoe A is operated. , is removably inserted into a locking ring 17 protruding from the rear end of the rectangular frame 4a on the rear end side of the canopy 4.

The movable component 4c rotates downward in the direction shown by the arrow in FIG. 2 about the axis of the rectangular frame 4a that pivotally supports the rotary sleeve 16, and moves to the canopy configuration position shown by the solid line. It is possible to move from a to a canopy support position b shown by a phantom line. Then, at the same position b, the movable component 4
The lower end of c can be removably inserted into and fixed to a locking ring 18 with a fixing bolt provided at the upper end of the flant handrail 11.

With this, the canopy 4 can be moved to the canopy support 13.
The canopy 4 and the canopy support 13 can be supported not only by the movable component 4c, but also by the movable component 4c.
During the removal work, etc., it is possible to reliably prevent the canopy 4 etc. from falling, and the canopy 4 etc. can be easily removed.
