Description

Technical Field

[0001] The invention relates to a suspended bottom-dumping hydraulic carriage, belonging to the technical field of coal mine transport equipment. Background Art

[0002] Coal mines often transport materials by mine cars, which run on tracks laid on the ground. In some crowded conditions, the ground is not large enough to lay tracks for mine cars, so materials are often transported in the air by hanging mine cars. When transporting materials in the air, materials are usually unloaded manually, which consumes manpower and increases the labor intensity of workers. At the same time, during the unloading process, material injuries are prone to occur. Summary of the invention

[0003] The technical problem to be solved by the present invention is to provide a suspended bottom-unloading hydraulic carriage to solve the problems existing in the prior art of transporting materials in the air, which requires manual unloading, which wastes working hours and increases labor intensity. At the same time, during the unloading process, materials are prone to injuring people, and other aerial transportation methods are difficult to operate and costly.

[0004] The technical solution adopted by the present invention is: a suspended bottom-unloading hydraulic carriage, including a box body, a connecting plate and a hydraulic cylinder. The box body is divided into two symmetrical half boxes. Two connecting plates are used. The upper and lower ends of each connecting plate are symmetrically hinged to the same end surface of the two half boxes through four hinge pins. The through holes at the hinged connecting plates of the two lower hinge pins are waist-shaped holes. The rotation center of the waist-shaped holes is the upper hinge pin. Two hydraulic cylinders are used. The two ends of each hydraulic cylinder are horizontally hinged on the same end surface of the two half boxes and are located below the connecting plate. Symmetrical notches are provided at the upper end of the box division.

[0005] Preferably, the bottom surfaces of the two halves of the box body are sloped structures with a trapezoidal cross section, which are inclined downward toward the center dividing surface of the box body, and a right-angle base is arranged outside the bottom side of the sloped surface.

[0006] Preferably, a hanging hole is provided on the middle side of the top of the connecting plate, and hinge holes are provided on both ends of the upper side.

[0007] Preferably, the hydraulic cylinder is hinged to the U-shaped groove of each half box.

[0008] Beneficial effects of the present invention: Compared with the prior art, the effects of the present invention are as follows:

[0009] (1) The present invention realizes automatic unloading by driving the two halves of the box to rotate symmetrically through a hydraulic cylinder. The device is simple, reliable, convenient and quick to operate, time-saving and labor-saving, greatly improving efficiency and greatly reducing labor intensity. The invention can realize remote control and avoid close-range operation, greatly improving safety, so as to solve the problems of manual unloading after suspended transportation of materials, which wastes working hours and increases labor intensity. At the same time, during the unloading process, materials are prone to injuring people.

[0010] (2) The waist-shaped hole of one half box on the same side rotates relative to the hinge pin, which plays a role in limiting and directing, and can improve the connection stability of the half box joints. A gap is set to avoid interference between the two half boxes during rotation. A slope structure is adopted to facilitate the automatic falling of materials by gravity after the half box is opened, so that the unloading is complete. BRIEF DESCRIPTION OF THE DRAWINGS

[0013] The present invention is further described below in conjunction with the accompanying drawings and specific embodiments.

[0014] Example 1: Figure 1-Figure 2 As shown, a suspended bottom-unloading hydraulic carriage comprises a box body 1, a connecting plate 2 and a hydraulic cylinder 4. The box body 1 is divided into two symmetrical half boxes 101. Two connecting plates 2 are used. The upper and lower ends of each connecting plate 2 are symmetrically hinged to the same end surface of the two half boxes 101 through four hinge pins 5 respectively. The through holes 8 at the hinged connecting plates 2 of the two lower hinge pins 5 are waist-shaped holes. The rotation center of the waist-shaped holes is the upper hinge pin 5. Two hydraulic cylinders 4 are used. The two ends of each hydraulic cylinder 4 are horizontally hinged to the same end surface of the two half boxes 101 and are located below the connecting plate 2. Symmetrical notches 102 are provided at the upper end of the divided part of the box body 1 to avoid interference between the two half boxes during rotation.

[0015] Preferably, the bottom surface of the two halves of the box 101 is a slope structure with a trapezoidal cross section, which is inclined downward toward the center dividing surface of the box 1. A right-angle base 3 is provided on the outside of the bottom side of the slope to facilitate keeping the bottom stable when placing the box.

[0016] Preferably, a hanging hole 6 is provided at the middle side of the top of the connecting plate 2, and hinge holes 7 are provided at both ends of the upper side.

[0017] Preferably, the hydraulic cylinder 4 is hinged to the U-shaped groove 9 of each half box 101 .

[0018] Working principle: In use, the connecting plate hinges the two half boxes into one box through four hinge pins in two rows, the iron chain hook of the monorail crane is hung on the hanging hole on the top of the connecting plate, and the carriage box is suspended in the air. The cylinder rod in the hydraulic cylinder installed on the surface of the box is extended by controlling the extension of the cylinder rod, and the two half boxes are driven to rotate along the two hinge pins in the upper row under the action of the limiting waist-shaped holes. The bottom of the box is opened, and the material is unloaded through the gap opened at the bottom. After unloading, the two half boxes are rotated again by controlling the cylinder rod to contract, and the bottom is closed and moved to the set position for reloading. The device of the present invention is simple, reliable, and easy to operate, so as to solve the problems of manual unloading after suspended transportation of materials, which consumes working hours and increases labor intensity. At the same time, materials are prone to injuring people during the unloading process.
