Abstract
Description
Technical Field
[0001] This utility model relates to a monorail crane for personnel transport in coal mine working faces. Background Technology
[0002] As the coal mine tunneling face advances, the length of the roadway gradually increases. Workers on the face must walk a long distance each day to reach the working face, by which time they are exhausted. Similarly, after a long day of intense work, workers on the mining face must walk a long distance to reach the personnel carrier. This long walking distance significantly increases the workload and is detrimental to safe production. Therefore, this paper designs a personnel carrier system using a monorail traction device in the working face roadway. This avoids the long walking distances for workers traveling to and from the working face, saves their energy, and is more conducive to safe production. Summary of the Invention
[0003] The technical problem to be solved by this utility model is to provide a monorail personnel transport device for mining faces that can avoid long-distance walking for workers traveling back and forth to the working face, and has high transportation efficiency and stable operation.
[0004] The purpose of this utility model is achieved as follows: It includes a frame, and the top of the frame is connected to two sets of pulleys on the left and right sides by a pivot. The two sets of pulleys are respectively placed in the grooves on the left and right sides of the existing monorail track in the mine. The frame can be moved by the movement of the pulleys in the monorail track. A downwardly extending connecting rod is rotatably connected to the frame, and a passenger seat is installed at the lower end of the connecting rod. A braking device is also installed on the frame.
[0005] The passenger seat is fixed with a sleeve at one end, which is fitted onto the lower end of the connecting rod. A limit plate is fixed to the bottom end of the connecting rod. The limit plate prevents the sleeve from falling off the connecting rod. The direction of the passenger seat can be adjusted by rotating the sleeve.
[0006] The limiting plate has two corresponding limiting grooves, which are on the same straight line. A limiting seat is fixed on the sleeve. The limiting seat has a groove in the middle. The limiting seat above and below the groove has a limiting pin mounting through hole. The two through holes are on the same vertical line. The limiting pin is installed in the limiting pin mounting through hole, and its upper and lower ends protrude from the limiting seat. A washer is fixed on the limiting pin in the groove. A first spring is sleeved on the limiting pin above the washer. The upper end of the first spring abuts against the top wall of the groove, and the lower end of the first spring abuts against the washer. The lower end of the limiting pin is inserted into the limiting groove of the limiting plate to limit the seat after the direction is adjusted.
[0007] The seat is equipped with footrests.
[0008] The braking device includes a handle, the inner end of which (i.e., the end closest to the frame) is hinged to the frame, and the lower end of the vertical rod is hinged to the handle. The hinge point between the vertical rod and the handle is located outside the hinge point between the handle and the frame. A sleeve is fixed on the frame, and the vertical rod is slidably disposed in the sleeve with both its upper and lower ends extending out of the sleeve. A connecting seat is fixed to the top of the vertical rod, and a second spring is sleeved on the vertical rod between the connecting seat and the sleeve. One end of the second spring is fixed to the connecting seat, and the other end is fixed to the sleeve. The upper ends of two short diagonal rods located on both sides of the vertical rod are hinged to the connecting seat, and the lower ends of the two short diagonal rods are respectively hinged to the lower ends of two long diagonal rods. The middle parts of the two long diagonal rods are respectively hinged to the left and right sides of the frame. The upper ends of the two long diagonal rods are respectively fixed with crossbars extending towards the monorail track. The frame has elongated holes at the corresponding crossbar positions, and a brake pad is fixed to the end of the crossbar facing the monorail track after passing through the elongated holes.
[0009] The short diagonal bar gradually slopes outward from top to bottom, and the upper diagonal bar gradually slopes outward from bottom to top, that is, the two short diagonal bars and the two long diagonal bars form an approximate W shape.
[0010] Several of these devices are connected together front and rear by a connecting rod. That is, the two ends of the connecting rod are respectively connected to the frame of two adjacent devices.
[0011] The advantages of this invention are: by using the existing monorail track in the underground mining face roadway and the traction of the monorail locomotive to transport workers, it solves the problem of increased labor intensity caused by long-distance walking for workers traveling to and from the working face. Furthermore, this device features high transportation efficiency, stable operation, and a simple structure. When not transporting personnel, the passenger seat can be removed for auxiliary transport using the monorail. Attached Figure Description

[0017] The following is combined Figure 1-5 The present invention will be further described below;
[0018] It includes a frame 1, with two sets of pulleys 2 connected to the top of the frame via a pivot. The two sets of pulleys are placed in the grooves on the left and right sides of the existing monorail track 3 in the mine. The frame can be moved by the movement of the pulleys in the monorail track. A downwardly extending connecting rod 4 is rotatably connected to the frame, and a passenger seat 5 is installed at the lower end of the connecting rod. A braking device is also installed on the frame.
[0019] The passenger seat is fixed with a sleeve 6 at the end, which is sleeved on the lower end of the connecting rod. The bottom end of the connecting rod is fixed with a limit plate 7. The limit plate can prevent the sleeve from falling off the connecting rod. The direction of the passenger seat can be adjusted by rotating the sleeve.
[0020] The limiting plate has two corresponding limiting grooves 8, which are on the same straight line. A limiting seat 9 is fixed on the sleeve. The limiting seat has a groove in the middle. The limiting seat above and below the groove has a limiting pin mounting through hole. The two through holes are on the same vertical line. The limiting pin 10 is installed in the limiting pin mounting through hole, and its upper and lower ends protrude from the limiting seat. A washer 11 is fixed on the limiting pin in the groove. A first spring 12 is sleeved on the limiting pin above the washer. The upper end of the first spring abuts against the top wall of the groove, and the lower end of the first spring abuts against the washer. The lower end of the limiting pin is inserted into the limiting groove of the limiting plate to limit the seat after the direction is adjusted.
[0021] When the seat direction needs to be adjusted, pull up the limiting pin to disengage it from the limiting groove of the limiting plate. At this time, the first spring is compressed. Rotate the seat until it rotates 180° and the limiting pin is located in another limiting groove of the limiting plate. Release the limiting pin, and under the reset action of the first spring, the limiting pin is inserted into the limiting groove, thus limiting the seat position.
[0022] The seat is equipped with footrests 22.
[0023] The braking device includes a handle 21, the inner end of which (i.e., the end near the frame) is hinged to the frame, and the lower end of the vertical rod 13 is hinged to the handle. The hinge point between the vertical rod and the handle is located outside the hinge point between the handle and the frame. A sleeve 14 is fixed on the frame. The vertical rod is slidably disposed in the sleeve and extends from the sleeve at both ends. A connecting seat 15 is fixed to the top of the vertical rod. A second spring 16 is sleeved on the vertical rod between the connecting seat and the sleeve. One end of the second spring is fixed to the connecting seat, and the other end is fixed to the sleeve. The upper ends of two short diagonal rods 17 located on both sides of the vertical rod are hinged to the connecting seat. The lower ends of the two short diagonal rods are respectively hinged to the lower ends of two long diagonal rods 18. The middle parts of the two long diagonal rods are respectively hinged to the left and right sides of the frame. The upper ends of the two long diagonal rods are respectively fixed with crossbars 19 extending towards the monorail track. The frame has elongated holes at the corresponding crossbar positions. After the crossbar passes through the elongated holes, a brake pad 20 is fixed to the end facing the monorail track.
[0024] The short diagonal bar gradually slopes outward from top to bottom, and the upper diagonal bar gradually slopes outward from bottom to top, that is, the two short diagonal bars and the two long diagonal bars form an approximate W shape.
[0025] When braking is required, pull down the handle. The handle moves the vertical rod and the connecting seat downwards. The connecting seat moves the short diagonal rod downwards, while the long diagonal rod rotates along the hinge point between the long diagonal rod and the frame. This causes the upper end of the long diagonal rod to move towards the monorail until the brake pads are against the side of the rail, thus achieving braking.
[0026] This device is operated by a monorail crane.
[0027] Several of these devices are connected together front and rear by connecting rod 23. That is, the two ends of the connecting rod are respectively connected to the frame of two adjacent devices. After connection, the distance between two devices is greater than 1 meter.
[0028] The above are merely preferred embodiments of this utility model and do not limit the patent scope of this utility model. Any equivalent structural or procedural transformations made based on the description and drawings of this utility model, or direct or indirect applications in other related technical fields, are similarly included within the patent protection scope of this utility model.
