Description

Technical Field

[0001] The present disclosure belongs to the field of coal mine transportation, and particularly relates to a single-track crane running attitude adjustment device for large-deformation roadways. Background Art

[0002] Single-track crane transportation is a system that uses a special I-beam suspended above the roadway as a track, connects suspension vehicles with various functions into a vehicle group, and is towed by a traction device to run along the track. At present, the auxiliary transportation in the working faces of most coal mines in China widely adopts the method of using small winches for pulling in pairs and relay transportation. This transportation method has low transportation capacity, many transportation links, a large number of occupied equipment, a large number of occupied personnel, requires a large number of intermediate yards to be laid, and has great potential safety hazards, becoming a long-standing and difficult problem restricting the safety and mechanization development of mines. To accelerate the modernization of coal mine auxiliary transportation in China, single-track crane transportation, as a new transportation method, overcomes the transportation condition limitations of rail-bound vehicles, enables multiple roadways to be connected and used, can be applied in roadways with multiple bends and undulations, and has strong flexibility and adaptability. Promoting and applying single-track crane transportation has important practical significance for improving the transportation environment, increasing transportation efficiency, and ensuring transportation safety.

[0003] Since single-track crane transportation is fixed by a suspension method, the single-track crane is prone to swing, and in complex underground transportation situations, the single-track crane often rubs against the roadway side and floor heave, thus inducing extrusion accidents.

[0004] Single-track crane transportation is fixed by a suspension method, and during the operation process, it is unable to timely adjust to changes in roadways, etc. All parts of the single-track crane often rub against the roadway side, floor heave, and objects stored in the roadway, causing the carriage to be extruded and deformed. In severe cases, it may cause extrusion accidents and result in casualties. Therefore, there is an urgent need for a new type of single-track crane that can adjust its attitude during the operation process to avoid unnecessary rubbing and collisions during transportation, so as to ensure the safety and stability of the single-track crane during driving.

[0039] Please refer to Figures 1 to 8 , a single-track crane driving attitude adjustment device for large-deformation roadways, including a running track 5, a running suspension wheel 4, and a transport carriage body 1. The running suspension wheel 4 is slidably clamped on the running track 5, and the transport carriage body 1 is connected to the running suspension wheel 4 through a connecting member;

[0040] An adjustment chamber 2 is provided inside the transport carriage body 1. The adjustment chamber 2 includes an adjustment body 2-1 slidably connected inside the transport carriage body 1. Hydraulic cylinders 2-3 are arranged on both sides of the adjustment body 2-1, and the piston rods 2-5 at the output ends of the hydraulic cylinders 2-3 abut against the peripheral wall of the adjustment body 2-1;

[0041] One end of the transport carriage body 1 is connected to a driving head 3. The driving head 3 includes a cockpit 3-1, a driving control console 3-3, a monitoring unit, and a hydraulic adjustment unit. The driving control console 3-3 is arranged inside the cockpit 3-1. The monitoring unit is arranged on the cockpit 3-1 and is used to monitor the running attitude. The hydraulic adjustment unit is used to control the telescoping of the piston rods 2-5 at the output ends of the hydraulic cylinders 2-3;

[0042] By monitoring the running attitude through the monitoring unit, the driver controls the hydraulic cylinders 2-3 through the driving control console 3-3 and the hydraulic adjustment unit, adjusts and transforms the position of the adjustment body 2-1, and further realizes the adjustment of the posture by changing the center of mass of the single-track crane through a swinging method, so as to avoid scraping and collision with the deformed roadway side and the uplifted floor and ensure safe transportation.

[0043] There is a steel plate fixed inside the transportation carriage body 1, and the space at the lower end of the steel plate is the adjustment bin 2.

[0044] On the inner bottom surface of the adjustment bin 2, a cylinder track 2-2 is fixed. The adjustment body 2-1 is slidably connected to the cylinder track 2-2. The hydraulic cylinders 2-3 on both sides of the adjustment body 2-1 are respectively fixed on the two side walls of the adjustment bin 2, and the hydraulic cylinders 2-3 are all placed coaxially with the cylinder track 2-2; this can improve the guiding property during the movement of the adjustment body 2-1.

[0045] The adjustment body 2-1 is a solid sphere. At one end of the piston rod 2-5 close to the adjustment body 2-1, an arc plate is fixed, and the arc plates are all in contact with the peripheral wall of the adjustment body 2-1; this can improve the stability of the contact between the piston rod 2-5 and the adjustment body 2-1.

[0046] The monitoring unit includes a level 3-2 and a laser instrument 3-5. The laser instrument 3-5 is fixed at the bottom of the cab 3-1, and the level 3-2 is fixedly installed on the driving operation console 3-3.

[0047] The transportation carriage body 1 is set to be multi-section, and adjacent transportation carriage bodies 1 are connected to each other.

[0048] The hydraulic adjustment unit includes an oil storage tank 3-6 arranged in the cab 3-1. There is a pipe cabin 3-4 at the lower end of the cab 3-1. A pair of hydraulic pipes 6 are laid in the pipe cabin 3-4. The hydraulic pipes 6 correspond to the hydraulic cylinders 2-3 on both sides of the adjustment body 2-1 one by one. One end of the hydraulic pipe 6 extends into the oil storage tank 3-6 and is connected to a pressure pump 3-7, and the other end of the hydraulic pipe 6 sequentially penetrates through the adjustment bins 2 in each transportation carriage body 1;

[0049] Any one of the hydraulic pipes 6 includes an oil outlet pipe 6-2 and an oil inlet pipe 6-1 wrapped in a hose. Inside each adjustment bin 2, the oil inlet pipe 6-1 and the oil outlet pipe 6-2 are both exposed and are connected to the corresponding hydraulic cylinder 2-3 through an external connection pipe 6-3. And an electro-hydraulic valve 2-4 is provided between the external connection pipe 6-3 connected to the oil outlet pipe 6-2 and the corresponding hydraulic cylinder 2-3;

[0050] The working method is as follows:

[0051] This device runs on the monorail crane running track 5 through the running pulley 4. The spirit level 3-2 is used to detect the smoothness of the monorail crane's operation. The driver judges the swinging direction and amplitude of the monorail crane according to the offset of its indicator. By observing the continuity of the light emitted by the laser instrument 3-5, it is judged whether there is a floor heave and whether the distance between the two sides of the roadway changes, so as to facilitate the driver to issue a posture adjustment command in time. When the environment of the running roadway changes, the driver in the cockpit 3-1 operates the control device on the driving operation console 3-3 to issue an instruction to the adjustment bin 2. The electric hydraulic valve 2-4 on the side where the adjustment body 2-1 is away from is closed, so that the outer connecting pipe 6-3 connected to the oil outlet pipe 6-2 is closed. The electric hydraulic valve 2-4 on the other side is opened, and the pressure pump 3-7 pressurizes, so that the hydraulic oil in the oil storage tank 3-6 enters the cylinder track 2-2 through the outer connecting pipe 6-3 connected to the oil inlet pipe 6-1. Through the telescopic cooperation of the hydraulic cylinders 2-3 on both sides of the adjustment body 2-1, the adjustment body 2-1 is pushed to adjust its position. Subsequently, the following carriages are synchronously adjusted according to the offset degree of the adjusted carriage, so that the center of mass of the monorail crane changes, thereby making its overall posture adjustment to facilitate safe passage through the changing roadway.

[0052] Taking the adjustment body as the origin and the vertical offset α angle as the positive direction to establish a coordinate system, the center of mass coordinates are:

[0053]

[0054] Where x: center of mass coordinates; L: moving distance of the adjustment body; M: mass of the monorail crane; m: mass of the adjustment body; r: radius of the adjustment body; a: side length of the monorail crane.

[0055] The monorail crane running posture adjustment device designed by the utility model adjusts its posture by pushing the adjustment body 2-1 through the hydraulic cylinder 2-3. The method is more convenient, fast and effective; at the same time, the hydraulic pipe 6 also connects each carriage together, systematizes the whole monorail crane, and can achieve unified scheduling and adjustment, enhancing the coordination ability and safety.
