Description

Wrecker with Boom Stand and Boom Rotator in Passenger Seats {WRECKER WITH BOOM ROTATION PART UNDER SEAT THEROF}

The present invention relates to a tow truck provided with a boom in the passenger seat, the crane unit consisting of a boom and the rotating shaft for rotating the boom and the boom to operate the boom to install a crane in a small freight car of less than 1 ton to tow, the boom And a hydraulic cylinder for moving and rotating the rotating shaft, a hydraulic generator for supplying hydraulic oil to the hydraulic cylinders, and a conventional traction device including a controller for controlling the operation of the crane unit. In order to lower the center of gravity of the driver's seat, the rotating part is mounted on the bottom of the driver's seat, and the base for safely supporting the rotating part is installed at the bottom of the passenger seat. The rigid pipe is welded and reinforced.

A tow truck is a vehicle for towing a broken down or illegally parked car and moving it to a repair shop or a legal place, and a boom, winch, tow bar, etc. are installed at the rear to tow the vehicle.

In other words, the traffic congestion is increasing as the number of vehicles and traffic is increasing, and a tow truck with rapid mobilization and safe towing ability is required at a time when the number of towed vehicles due to an accident is also increasing. If the towing capacity is more than necessary for safe towing, the speed is inferior, and the effective turning radius of the vehicle is large, which makes the towing work inconvenient and inefficient in terms of cost.

In addition, in order to tow the vehicle in the direction of travel in order to tow from the front or rear of the tow vehicle, the tow vehicle is difficult to tow when there is an obstacle such as another vehicle in the front and rear of the tow vehicle. Since the vehicle is driven by lifting only one side of the front wheel or the rear wheel, it is necessary to lower the center of gravity and there should be no problems with the steering system, braking system, suspension system, etc. in the towed state.

Korean Utility Model Registration No. 0280709 Although FIG. 1 to FIG. 3 are difficult to apply to a small freight car of less than 1 ton, it has the advantage that the towed vehicle can be towed in a narrow space through the lifting fork 40 in the lateral direction, As shown in FIG. 1, the front wheel lifting unit 10 and the rear wheel lifting unit 20 for separately lifting the front wheels and the rear wheels of the towed vehicle are separately configured to complicate the device and increase the weight of the vehicle, thereby providing braking ability and towing capability. There is a problem that reduces.

In addition, a pair of support arms (1, 2) (4, 5) supporting the front wheel and the rear wheel of the tow vehicle, respectively, is hinged (1a, 2a) (4a, 5a) to each lifting frame (3) (6), respectively. By having a structure that is connected to, there is a problem that the towing vehicle is rocked when the support arms (1, 2) (4, 5) support the front wheel and the rear wheel to lift up.

In addition, when the towed vehicle is tolerated from one side, the load is biased, and even though the outriggers are installed at the front, rear, left and right sides, the load is concentrated on one outrigger due to the one-sided load. There is this.

In addition, Korean Patent No. 10-0555442 is also a side towing, but stability has been improved, but due to the complexity and weight of the towing device, the output of the tow vehicle is also increased and the vehicle body becomes large.

Al-veh vehicles with normal loading bins are in accordance with the requirements of the trucks. The floor area of the loading bins is not less than 2㎡ and the partition between passenger seats and cargo compartments is divided by bulkheads. In other words, it is a vehicle with a minimum requirement to be provided as a pickup truck, commonly referred to as a pickup, and has a suspension device such as a passenger car, and has a space for loading a small amount of cargo, making it difficult to install a traction device such as a crane due to a narrow cargo compartment. The rotating part of the arm is the opposite point of the arm that receives the load due to the towing of the vehicle, so it is required to be firmly coupled to the body frame because it requires weight and rigidity by receiving the floating force during shock or vibration. It is difficult to bond firmly. In addition, the increase in weight due to the reinforcing device and the structure reinforcement added to the above ALV freight vehicle may require the excess of the rear wheel axial weight and the braking system as well as the suspension system in accordance with the overload weight.

Therefore, the present invention was created in order to solve the above problems, but does not limit the type of the vehicle, but the two-row passenger seat seat of the rear seat and the driver's seat with an al-veh vehicle equipped with a four-wheel drive type loading box having mobility and high output It removes unnecessary parts of the back and reduces the weight of the vehicle and minimizes the weight of the added traction device by using high rigidity metal material to satisfy the rear wheel celebration, eliminating the need for supplementary suspension or braking system. By reinforcing the floor with a grid-shaped rigid pipe, the crane pivot can be installed to lower the center of gravity of the vehicle, and it can be placed closer to the front wheel than to install the crane pivot to the load compartment to increase the safety by adjusting the load distribution ratio before and after. Make sure In addition, by cutting a portion of the partition between the cargo box and the passenger seat to install a bellows-shaped cover to prevent interference with the operation of the boom smoothly without the inflow of dust or rain water.

As described above, the present invention has the following advantages.

First, it is possible to improve the stability by lowering the center of gravity by installing the crane pivot and the boom in the passenger seat according to the present invention.

Second, in the conventional tow trucks, the crane rotating part is vulnerable to dust due to the injection of lubricating grease to reduce frictional resistance and smooth operation, but the towing vehicle according to the present invention has a dust or foreign material by placing the rotating part at the bottom of the passenger seat. It is possible to prevent the inflow of.

Third, since the crane pivot is installed at the lower center of the second row of passenger seats, the passenger seats in the left and right rows of two rows are not affected by the operation of the crane.

Fourth, it is possible to tow the tow vehicle by placing the crane turning part in front of the rear wheel, and to suppress the floating force due to the fluctuation when driving, and the slip phenomenon that is caught by the rear wheel of the tow vehicle due to the centrifugal force generated by the tow vehicle when turning left and right. Can be suppressed.

2 is a side perspective view of a conventional tow vehicle
3 is a side perspective view of a wire-type tow vehicle according to the present invention;
4 is a reinforcing example of a frame for installing the pivot base;

The fundamental purpose of the present invention relates to a tow truck using an Alv lorry. In general, an Alv lorry produced in Korea has a small load and is limited to be used as a tow truck when the traction device is attached.

Therefore, the present invention is to reduce the weight of 250kg by removing parts such as the back seat and the loading seat in order to reduce the weight as much as possible, using a high rigid pipe boom to reduce the weight of the boom structure is additionally installed, the boom pivot The frame for installation also does not necessarily limit the high rigidity pipe, but as shown in Fig. 4, the frame is welded to the frame and provided with a light rotating part having gears on the outer circumference.

In this case, as shown in FIGS. 1 to 3, the boom can be fixed at a height within only 100 mm from the bottom of the passenger seat, so that the center of gravity can be lowered, thereby improving stability. In addition, even in the center of gravity of the front and rear of the vehicle is installed on the bottom of the second row of passenger seats can be evenly distributed.

In addition, PTO (power take-off) to get the power to raise or lower the boom is connected to the main shaft of the engine to drive the hydraulic pump to operate the hydraulic cylinder. Alternatively, one of the alternatives can be made by pulling using wires without using hydraulic cylinders.
