Description

Technical Field

[0001] The present invention belongs to the technical field of unit support handling mechanisms, and specifically discloses a folding and flipping unit support handling mechanism. Background Art

[0002] In the application of unit supports in gob-side entries, the most critical technology is to ensure the rapid support movement of unit supports. The unit support needs to move from both sides of the roadway to the center line of the roadway, then move along the center line of the roadway, and then move from the center of the roadway to the designated support position to form a cyclic and non-repeated support. There are various traditional underground auxiliary transportation methods, which are affected by various factors such as gas, coal dust, and terrain, and are mainly divided into track transportation and trackless transportation. Track transportation mainly includes single-track hoists, mine winches, and endless-rope haulage vehicles, etc., and trackless transportation mainly refers to the transportation of trackless rubber-tired vehicles. With the continuous in-depth research, currently, new types of underground auxiliary transportation methods include a mine fork-mounted unit support carrier vehicle disclosed in CN112390195A and a mine explosion-proof battery-driven new energy unit support carrier vehicle disclosed in CN114803960A. However, the handling mechanisms of such unit support carrier vehicles have the following problems:

[0003] 1. When the fork plate rotates to ±90°, the parts of the fork plate on both sides of the rotary oil cylinder are in a suspended state and a state supported by the cantilever beam respectively. When inserting into the unit support, the two parts are unevenly stressed, and the fork plate is prone to deformation;

[0004] 2. The overall structure of the handling mechanism is complex and large in volume. Summary of the Invention

[0005] The present invention provides a folding and flipping unit support handling mechanism to solve the problems described in the background art.

[0006] The above-mentioned folding and flipping unit support handling mechanism includes a rear frame, an intermediate frame, an intermediate frame flipping drive part, a front frame, a front frame flipping drive part, a support shovel plate, and a shovel plate flipping drive part; there are two groups of vertically opposite hinge points on the intermediate frame, and the two groups of hinge points are respectively hinged to the rear frame and the front frame; the intermediate frame is driven by the intermediate frame flipping drive part to flip left and right around the hinge point between the intermediate frame and the rear frame, with a minimum flipping angle of 0 and a maximum flipping angle of 90°; the front frame is driven by the front frame flipping drive part to flip left and right around the hinge point between the intermediate frame and the front frame, with a minimum flipping angle of 0 and a maximum flipping angle of 90°; the support shovel plate is hinged to the front side of the front frame and is driven by the shovel plate flipping drive part to flip up and down, with a minimum flipping angle of 0 and a maximum flipping angle of 90°.

[0007] Furthermore, the intermediate frame is connected to the rear frame through hinge ears and hinge shafts, the front frame is connected to the intermediate frame through hinge ears and hinge shafts, and the support shovel plate is connected to the front frame through hinge ears and hinge shafts.

[0008] Furthermore, the intermediate frame flipping drive unit, the front frame flipping drive unit, and the shovel plate flipping drive unit are all oil cylinders.

[0009] Furthermore, an avoidance groove is provided at the top of the intermediate frame and the rear frame. An oil cylinder mounting ear Ⅰ is installed on the avoidance groove, and both ends of the intermediate frame flipping oil cylinder are hinged to the two oil cylinder mounting ears Ⅰ respectively; an avoidance hole is provided in the middle of the front frame, and oil cylinder mounting ears Ⅱ are provided at the top of the avoidance hole and the front side of the intermediate frame. Both ends of the front frame flipping oil cylinder are hinged to the two oil cylinder mounting ears Ⅱ respectively; oil cylinder mounting ears Ⅲ are provided at the bottom of the avoidance hole and on the support shovel plate, and both ends of the shovel plate flipping oil cylinder are hinged to the two oil cylinder mounting ears Ⅲ respectively.

[0010] The present invention has the following beneficial effects:

[0011] 1. When the support shovel plate rotates to the left or right and is inserted into the unit support, the two support shovel plates are evenly stressed, the rotating shaft is not easily deformed, and the service life is long;

[0012] 2. The overall structure of the handling mechanism is simple, and the volume is small when the support shovel plate, the front frame, and the intermediate frame are completely retracted;

[0013] 3. This mechanism can realize the 90° flipping of the support shovel plate and can also realize the function of the support shovel plate swinging to the left and right sides, meeting the functions required for unit support handling, effectively improving the handling efficiency of the unit support, reducing the labor intensity, and ensuring the safety of the support handling process.

[0025] Embodiment 2

[0026] Figures 1-3Among them, the middle frame 2 is a left flipping frame, and the front frame 3 is a right flipping frame. Two single hinge ears are arranged on the left side of the middle frame 2, and two upper and lower groups of double hinge ears are arranged on the left side of the rear frame 1. The single hinge ears on the left side of the middle frame 2 are embedded in the middle of the double hinge ears on the left side of the rear frame 1 and are connected by a hinge shaft. Two upper and lower groups of double hinge ears are arranged on the right side of the middle frame 2, and two single hinge ears are arranged on the right side of the front frame 3.

The front frame flipping oil cylinder 6 stretches outwards, pushing the front frame 3 to swing towards the right front until the front frame 3 is parallel to the unit support; then the shovel plate flipping oil cylinder 7 stretches, so that the support shovel plate 4 extends between the top beam of the unit support and the base of the unit support and flips upwards at the same time until it forms a 90° angle with the initial position, as shown in Figure 2 the figure; the unit support columns contract, the top beam of the unit support first contacts the support shovel plate 4, and the unit support columns continue to contract until the base of the unit support is suspended; finally, the front frame flipping oil cylinder 6 contracts inwards, driving the front frame 3 back to the initial position, and the unit support swings to the front of the folding and flipping type unit support handling mechanism, completing a complete right-side unit support handling operation.

[0028] When the unit support to be handled is at the left front of the folding and flipping type unit support handling mechanism, the initial state of the handling mechanism is still as shown in Figure 1 the figure. At this time, the middle frame flipping oil cylinder 5 stretches outwards, pushing the middle frame 2 to swing towards the left front until the middle frame 2 is parallel to the unit support; then the shovel plate flipping oil cylinder 7 stretches, so that the support shovel plate 4 extends between the top beam of the unit support and the base of the unit support and flips upwards at the same time until it forms a 90° angle with the initial position, as shown in Figure 3 the figure; the unit support columns contract, the top beam of the unit support first contacts the support shovel plate 4, and the unit support columns continue to contract until the base of the unit support is suspended; finally, the middle frame flipping oil cylinder 5 contracts inwards, driving the middle frame 2 back to the initial position, and the unit support swings to the front of the folding and flipping type unit support handling mechanism, completing a complete left-side unit support handling operation.
