Embodiment 1

Please refer to Figure 1-2, a coal mine material loading vehicle, including a body 1, a power system 2 and a control system 3, the body 1 includes a main frame and a walking mechanism at the bottom, the power system 2 is installed on the main frame, and the power system 2 Including the explosion-proof engine system and hydraulic system, the explosion-proof engine outputs power, drives the hydraulic pump, and provides power for the hydraulic system. Hydraulic oil source, the control system 3 includes a local operating system and a remote control system, a hoisting system 4 and a fixing device 5 are installed on one end of the main frame surface of the body 1, and an anti-collision system 6 is installed on the edge of one end of the main frame, and an anti-collision system 6 is installed. It includes ranging sensor and controller. When the object to be lifted is close to the ranging sensor and less than the set safe distance during the lifting process, an alarm will be issued to p...

Embodiment 2

see image 3 The embodiment is further optimized on the basis of Embodiment 1. Specifically, the connecting rod 9 is replaced with a luffing cylinder 15, and the hoisting cylinder 7 is installed from the middle of the forearm 8 to the top of the forearm 8.

[0019] In this embodiment, when the weight of the object to be lifted is relatively large, the hoisting system 4 can replace the connecting rod 9 with the luffing cylinder 15. In this way, the original four-link mechanism becomes a variable-rod and long four-link mechanism, and the lifting cylinder is increased. 7. The force arm increases the lifting force, and the lifting position can be changed without changing the size of the crane, which solves the problem that the size of the lifting mechanism of the same lifting level is too large and cannot be used underground.

Embodiment 3

Referring to FIG. 4 , the present embodiment is optimized as follows on the basis of Example 1 or Example 2. Specifically, a magneto-induced displacement sensor 16 is provided inside the telescopic oil cylinder 11 .

[0021] In this embodiment, the magnetic displacement sensor 16 is installed in the telescopic oil cylinder 11, which can record the cylinder stroke in real time. When the anti-collision system 6 issues an alarm, the operating system automatically locks the operation solenoid valves of the lifting oil cylinder 7 and the luffing oil cylinder 15, and Actively control the telescopic cylinder 11 to extend the specified length L, and the system automatically determines whether the alarm is in contact. If it is still at a safe distance, the telescopic cylinder 11 extends the specified length L again until the alarm is lifted. At the same time, the hoisting cylinder 7 and the luffing cylinder 15 are automatically unlocked.

[0022] To sum up: the present invention adopts t...

Abstract

The invention discloses a coal mine material loading and transporting vehicle, and relates to the technical field of coal mine loading and transporting equipment, the coal mine material loading and transporting vehicle comprises a machine body, a power system and a control system, a hoisting system comprises two sets of hoisting oil cylinders, small arms, connecting rods and large arms, one ends of the hoisting oil cylinders are hinged to the machine body, and the other ends of the hoisting oil cylinders are hinged to the middles of the small arms; one end of the small arm is hinged to the machine body, the other end of the small arm is hinged to one end of the connecting rod, the end, away from the small arm, of the connecting rod is hinged to the middle of the large arm, one end of the large arm is hinged to the machine body, and a telescopic arm is slidably connected into the other end of the large arm. Through the arrangement of the hoisting system and the cooperative arrangement of the hoisting oil cylinder, the small arm, the connecting rod, the large arm, the telescopic oil cylinder and the telescopic arm, the hoisting arm adopts a connecting rod mechanism, so that the occupied space is reduced, and the problems that a cargo boom type hoisting mechanism can only be arranged approximately horizontally in an underground space, materials cannot be placed in a radius space of the cargo boom, and the hoisting efficiency is low are solved. And space waste is caused.

Description

technical field [0001] The invention relates to the technical field of coal mine loading and transportation equipment, and more particularly to a coal mine material loading vehicle. Background technique [0002] The material in the coal mine is large in size, heavy in weight, limited in space, and inconvenient to transport. The direct integration of the loading mechanism on the ground into the coal mine transportation equipment mainly has the following problems. First, the size of the hoisting mechanism of the same hoisting level is too large to be used underground; second, the boom-type hoisting mechanism can only be arranged nearly horizontally in the underground space, and materials cannot be placed in the radius space of the boom, resulting in equipment space waste. [0003] Therefore, it is necessary to propose a material loading vehicle for coal mines to solve the above problems. SUMMARY OF THE INVENTION [0004] The purpose of the present invention is: in order to...
