Abstract
Description
Technical fields:
[0001] This utility model relates to the technical field of underground support equipment in coal mines, and in particular to a cross-belt crawler support trolley. Background technology:
[0002] During coal mining, tunneling faces are typically excavated using tunneling machines. The coal and gangue produced during excavation are discharged to the rear via a conveyor at the tail of the tunneling machine. Transfer equipment is needed to move the coal and gangue out of the roadway and onto the main haulage roadway via a belt conveyor, and then to the surface. Traditionally, belt conveyors or scraper conveyors are continuously installed behind the tunneling machine to transport the gangue produced during excavation out of the roadway. As the tunneling progresses, the underground support team also needs to install support devices in the excavated roadway to support the roof. During continuous tunneling operations, the length of the belt conveyor needs to be continuously extended, and specialized personnel are required for support work. This requires a large number of people working underground, making the workflow complex and posing significant safety hazards.
[0003] Furthermore, after the tunneling and coal mining are completed, the temporary support equipment and conveyors in the relevant roadways need to be dismantled and transported again. The dismantling and transportation of the equipment requires special transport vehicles, making the dismantling and transportation work quite complicated. Utility model content:

[0018] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.
[0019] like Figure 1As shown: A cross-belt tracked support trolley includes a frame 1, a tracked traveling mechanism 2, belt idlers 3, an electric belt roller 4, a tail roller 5, a hydraulic support device 6, and a hydraulic control device 7. The tracked traveling mechanism 2 is fixedly installed on both sides of the frame 1. The tracked traveling mechanism 2 is driven by a motor, with power coming from its own generator or battery. The tracks can adapt to the complex terrain of underground tunnels. The frame 1 includes two parallel longitudinal beams 101, and several sets of belt idlers 3 are fixedly installed between the longitudinal beams 101. The belt idlers 3 include horizontal idlers 301 and inclined idlers 302, which are alternately installed on the two longitudinal beams 101. Between them, belt idlers 3 are used to support the belt. An electric belt roller 4 is installed at one end of the longitudinal beam 101, and a tail roller 5 is installed at the other end of the longitudinal beam 101. The tail roller 5 is connected to the two longitudinal beams 101 through a tail bracket 102. The height of the tail roller 5 is higher than that of the electric belt roller 4. A belt is wound around the electric belt roller 4 and the tail roller 5. The belt rests on each belt idler 3. In use, both ends of this utility model can be connected to the same device or to conveying equipment such as tunneling machines and belt conveyors. Coal and gangue fall onto the belt above the electric belt roller 4 at the head of the machine. The electric belt roller 4 drives the belt to rotate, conveying the material to the tail roller 5. The tail roller 5 is higher than the head of the machine. The rear conveyor facilitates the material falling from the tail roller 5 onto the rear conveyor. A hydraulic support device 6 is fixedly installed above the frame 1, and a hydraulic control device 7 is fixedly installed on one side of the hydraulic support device 6. The hydraulic control device 7 includes an oil tank, oil pump, filter, control valve, and electrical control module, and has the same structure as the control device for conventional hydraulic cylinders. The oil pump draws hydraulic oil from the oil tank to provide power to each cylinder. The control valve and electrical control module are electrically connected and can control the direction of the oil in the connecting pipes of each cylinder, thereby controlling the extension and retraction of each cylinder. A connecting lug 103 is provided at one end of the longitudinal beam 101 of the frame 1, and a fixing pin hole 104 is provided at the other end of the longitudinal beam 101. This utility model has the following characteristics. One method of using the cross-belt tracked support trolley is to connect multiple trolleys end-to-end. As the tunneling progresses, the number of support trolleys is gradually increased, and each support trolley is connected end-to-end in sequence. The frames 1 of two adjacent trolleys are connected to each other end-to-end by means of interlocking connecting lugs 103. Fixing bolts or fixing pins are inserted through fixing pin holes 104 to form a temporary fixed connection, ensuring the stability of the connection between the two support trolleys. In addition, it also includes hydraulic support legs 8. Two hydraulic support legs 8 are installed on each side of the frame 1. After the support trolley moves into position, it can use the hydraulic support legs 8 to support the ground, thereby adjusting the level of each support trolley to ensure the stability of the support and smooth transport between belts.
[0020] like Figure 2As shown: The hydraulic support device 6 includes a support platform 601, folding telescopic arms 602, folding hydraulic cylinders 603, connecting arms 604, a first hinge 605, a second hinge 606, a support top plate 607, and a top plate hydraulic cylinder 608. The support platform 601 is fixedly installed above the vehicle frame 1. Two folding telescopic arms 602 are installed on the top surface of the support platform 601. A connecting arm 604 is fixed between the two folding telescopic arms 602. The middle part of the connecting arm 604 is hinged to the telescopic end of the folding hydraulic cylinder 603. The fixed end of the folding hydraulic cylinder 603 is connected to the support platform 607. The support platform 601 is hinged, and one end of the folding telescopic arm 602 is hinged to the top surface of the support platform 601. The folding hydraulic cylinder 603 extends and retracts, driving the two folding telescopic arms 602 to fold and swing. The other end of the folding telescopic arm 602 is hinged to a first hinge 605. The two first hinges 605 are respectively hinged to the support top plate 607. The support top plate 607 swings up and down around the hinge axis where the first hinge 605 is hinged to the folding telescopic arm 602. A second hinge 606 is coaxially hinged in front of the position where the first hinge 605 is hinged to the support top plate 607. The second hinge 606 is lower... The top plate hydraulic cylinder 608 is hinged to its telescopic end, and the fixed end of the top plate hydraulic cylinder 608 is hinged to the folding telescopic arm 602. The extension and retraction of the top plate hydraulic cylinder 608 controls the angle of the supporting top plate 607. Simultaneously, the top plate hydraulic cylinder 608 moves up and down together with the folding telescopic arm 602. The hinge axis of the first hinge 605 hinged to the folding telescopic arm 602 is perpendicular to the hinge axis of the first hinge 605 hinged to the supporting top plate 607. The hinge axis of the second hinge 606 hinged to the top plate hydraulic cylinder 608 is perpendicular to the hinge axis of the second hinge 606 hinged to the supporting top plate 607. The hinged hinge shaft allows the supporting roof plate 607 to move up and down horizontally when the two folding telescopic arms 602 extend to the same length, adapting to different heights within the tunnel. When the two folding telescopic arms 602 extend to different lengths, the two sides of the supporting roof plate 607 are lifted to different heights. The hinges of the first hinge 605 and the second hinge 606 with the supporting roof plate 607 provide more degrees of freedom, allowing the supporting roof plate 607 to tilt appropriately within a certain range to adapt to complex geological conditions within the tunnel and provide good support for the roof within the tunnel.
[0021] like Figure 3As shown: The folding telescopic arm 602 includes a sliding sleeve 6021 and a telescopic cylinder 6022. One end of the sliding sleeve 6021 is hinged to the top surface of the support platform 601. The telescopic cylinder 6022 is movably sleeved inside the sliding sleeve 6021. The extension rod of the telescopic cylinder 6022 is hinged to the lower end of the sliding sleeve 6021. The cylinder body of the telescopic cylinder 6022 slides in contact with the inner wall of the sliding sleeve 6021. When the telescopic cylinder 6022 extends, it causes the cylinder body of the telescopic cylinder 6022 to extend out of the sliding sleeve 6021, and the cylinder body end of the telescopic cylinder 6022 protrudes out. The sliding sleeve 6021 is hinged to the lower end of the first hinge 605. The fixed end of the top plate hydraulic cylinder 608 is hinged to the telescopic cylinder 6022. The lower end of the cylinder body of the telescopic cylinder 6022 is provided with a hinge ear 6023, which is hinged to the fixed end of the top plate hydraulic cylinder 608. Therefore, when the telescopic cylinder 6022 moves, it simultaneously drives the top plate hydraulic cylinder 608 to move up and down synchronously. When adjusting the height of the supporting top plate 607, only the length of the telescopic cylinder 6022 needs to be controlled, which makes the adjustment convenient and the operation simple and reliable.
[0022] The supporting top plate 607 includes an outer frame 6071, a telescopic cylinder 6072, and a telescopic bracket 6073. The telescopic cylinder 6072 is fixedly installed on the outer frame 6071, and the telescopic cylinder 6072 is parallel to the two end edges of the outer frame 6071. The telescopic bracket 6073 is fixedly installed on the telescopic end of the telescopic cylinder 6072. In order to increase the support and protection area of the supporting top plate 607, an additional telescopic bracket 6073 is provided on the outer frame 6071 of the supporting top plate 607.
