Description

[Detailed Description of the Invention] [Industrial Application Field] The present invention relates to a construction vehicle for use in construction work such as maintenance of construction machinery.

[Prior Art] At construction sites, various types of work are carried out (for example, cutting edge replacement work for motor scrapers and bulldozers, unit replacement work for T/M (transmission), H/P (hydraulic pump), etc., various welding work,
Tire air filling work, air element cleaning work, mud removal work, sanding work, grease filling work, etc.) are frequently carried out, and each time workers are required to purchase mechanical parts, equipment, and tools necessary for the work. must be carried and moved.

Furthermore, as construction machines have become larger in recent years, the weight of parts, equipment, tools, etc. for these machines has become extremely heavy, and the burden on workers has also increased.

[The problem that the idea aims to solve]

As the above-mentioned machine parts, for example, the cutting edges weigh as much as 100 to 180 kg, it has become virtually impossible to transport them by hand. Because workers had to handle these heavy parts, equipment, tools, etc., they were forced to perform dangerous work, often causing back pain or injury.

Additionally, an air impact device is used to loosen bolts when replacing parts, but this device is heavy and difficult to work with, and it has been difficult to loosen rusty bolts with this device.

This invention was developed to solve this problem, and it makes work at construction sites safe and easy.
Moreover, it is an object of the present invention to obtain a vehicle for construction work that does not impose uneven loads on the vehicle.

[Means to solve the problem]

The construction work vehicle according to the present invention includes a vehicle equipped with a loading platform in which a space for placing replacement parts is formed, and a lifting magnet installed at the rear end of the loading platform, with a lifting magnet removably attached to the tip. A hydraulic crane device that suspends and transports objects using the electromagnetic force of a lifting magnet, outriggers placed on both sides of the rear end of the vehicle, and one side of the front of the loading platform. It is possible to store a generator that supplies power to the lifting magnet and pressurizes the hydraulic system, as well as tools such as a hydraulic impact wrench that is placed on the other front side of the loading platform and is connected to the hydraulic system. a tool box equipped with the same, a greasing wheel installed in the front central part of the loading platform, and an air compressor installed in the front central area of the loading platform adjacent to the greasing gear;
The vehicle is equipped with a roof provided in front of the loading platform to prevent the front part of the loading platform from getting wet, and a floodlight attached to the rear end of the vehicle.

[Effect]

In this invention, a hydraulic crane device installed at the rear end of the loading platform can easily attract and transport objects by turning on and off electromagnetic force.
Cargo handling time is shortened. Moreover, by equipping the tool box with equipment for construction work such as a hydraulic impact wrench, maintenance such as parts replacement of the construction machine can be performed by moving the machine to a desired replacement location, thereby reducing the time required for replacement work.

〔Example〕

Hereinafter, one embodiment of the present invention will be described based on FIGS. 1 to 3. In the figure, 1 is a car equipped with a loading platform 2.
A crane device 3 is provided at the rear end of the loading platform 2. This crane device 3 is provided with extensible outriggers 4 that extend outward on both sides of the vehicle 1 to support the body of the vehicle 1 when the crane is in use, and a hook 5 for suspending an object to be transported is provided at the tip. The attached arm device 6 is extendable, foldable, and rotatable around the arm 7. The hook 5 is composed of a lifting magnet, is detachably attached to the tip of the arm device 6, and is connected to the generator 1.
It receives power from 2 and uses electromagnetic force to attract objects to be transported, such as replacement parts. Furthermore, with this crane device 3, when an object to be transported, such as a cutting edge, is to be connected to or removed from the hook 5, the worker can operate a button at the work place where the object is to be connected or disconnected, and moreover, by turning on or off the magnetic force, the object to be transported can be moved. It can also be hung or dropped.

11 secures a space 2a at the rear of the loading platform 2 (right side in Fig. 2), and secures a space 2a at the front (second
In this embodiment, as shown in FIG. 2, the generator 12 is installed on the right side (upper side in the figure), and the tool box 13 is installed on the left side (lower side in the figure). A grease charger 14 and an air compressor 15 are respectively disposed in the center. The generator 12 was installed at one end of the loading platform 2 because
Operation and inspection of the generator 12 from outside the vehicle 1,
This is to make maintenance etc. easier, and the tool box 1
3 is installed at the other end of the loading platform 2 in order to make it easier to take out the tools in the tool box 13 from outside the vehicle and store them therein, thereby making the work more convenient.

16 is for preventing rain from hitting the work equipment 11.
A roof is provided on the loading platform 2 to cover the equipment 11. A tool box 13 is provided so that a hydraulic impact wrench can be stored, and also stores a grinder, a chisel, a floodlight, a lifting magnet, and other tools. Reference numeral 17 denotes a floodlight attached to the rear of the vehicle body.

Regarding the work performed by each of the above equipment, crane device 3 (in this example, a 2.9 ton remote control crane is used) performs crane work such as replacing units and parts, and is designed to allow workers to work independently. It is remote-controlled. generator 12
(for example, an engine welder) is used for repairing cracks and damage, and the air compressor 15 is used for repairing cracks and damage.
It is used for tasks such as filling air into tires and cleaning elements, and is also used as a power source for the hydraulic system of the crane device 3, lifting magnet, jet chisel, sander, etc. The hydraulic impact wrench is connected to the hydraulic system of the crane device 3 and is used to remove and install bolts when replacing cutting edges, but since it uses hydraulic pressure, the force is stronger compared to the conventional air impact device, so the bolt The removal and installation work becomes easier. If the lifting magnet is used to transport the cutting edge, the work will be easier, and the lifting magnet can be used to transport the cutting edge.
The use of the system also allows construction work to be carried out at night. The grease charger 14 is also used for filling construction machinery with grease.

In this embodiment, the vehicle 1 is realized by modifying a 4-ton flat body truck.

Since the present embodiment is configured as described above, there is no need for the worker to directly carry parts and the like during maintenance work on the construction machine, making it possible to significantly reduce the work burden. It also eliminates the need to move work equipment such as generators, compressors, tool boxes, etc., which greatly reduces work time and improves safety. For example, replacing a cutting edge, which conventionally required four or five workers, can be done by two people using the apparatus of this embodiment, resulting in labor savings. Furthermore, since a space 2a is secured behind the loading platform 2, parts before and after replacement can be placed in this space 2a, eliminating the need to separately prepare a vehicle for transporting parts and the like.

[Effect of idea]

As described above, according to the present invention, a hydraulic crane device is used to attract and transport objects by turning on and off electromagnetic force, reducing the burden of cargo handling work and improving efficiency. safety can be improved. In addition, by equipping the tool box with construction work equipment such as a hydraulic impact wrench, maintenance such as parts replacement of construction machinery can be carried out by moving to the desired replacement location, reducing replacement work time. be able to.
