Description

Technical Field

[0001] This invention relates to the technical field of track installation equipment for mining monorail cranes, and specifically to a stepping feeding device for a track installation vehicle for mining monorail cranes. Background Technology

[0002] Monorail systems are among the most important auxiliary transportation systems in coal mines and other mining enterprises. The foundation of a monorail system is the monorail track erected on various locations, including the roof of coal mine roadways. For a coal mine to transport materials, personnel, and equipment to designated locations using a monorail system, the monorail track must first be laid and installed. Furthermore, as the mine face advances, the monorail track must continuously extend forward. Currently, due to a lack of effective auxiliary equipment, coal mines and other mining enterprises require a large number of personnel to use simple tools such as hand-operated hoists and ladders for the installation of monorail tracks. This multi-person collaborative work is particularly demanding in material storage and loading, resulting in high manpower consumption, high labor intensity, low work efficiency, and significant safety hazards. Therefore, developing more efficient tools for laying and installing monorail tracks in coal mines is a pressing technical problem that needs to be solved in the industry. Summary of the Invention

[0003] The purpose of this invention is to address the problem of the lack of effective tools and equipment for laying and installing monorail tracks in coal mines in the prior art, and to provide a step-feeding device for a mining monorail track installation vehicle that is easy to load, store, and discharge materials.

[0004] The technical solution of the present invention is as follows: The step-feeding device for the mine monorail hoist track installation vehicle of the present invention has the following structural features: a storage rack for placing the monorail to be laid, a hydraulic hoist for lifting the storage rack and being connected to the storage rack on the mine monorail hoist track installation vehicle during use, a one-way displacement mechanism on the storage rack for moving the monorail to be laid one by one to a set position, and a position sensor on the storage rack for detecting whether the monorail to be laid has moved into place.

[0005] A further solution is: the aforementioned unidirectional displacement mechanism includes a displacement drive cylinder that is fixedly mounted on the track installation vehicle of a mining monorail crane during use, a rocker arm connected to the piston rod of the displacement drive cylinder, and two identical material transfer mechanisms that move synchronously during operation and are driven by the rocker arm and transmitted by the transmission shaft.

[0006] A further embodiment is as follows: The aforementioned material transfer mechanism includes a main drive shaft rotatably mounted on the storage rack, a one-way rotating pair mounted on the outer periphery of the main drive shaft and connected to the main drive shaft, a drive sprocket mounted on the outer periphery of the one-way rotating pair and connected to the one-way rotating pair, a driven shaft rotatably mounted on the storage rack, a bearing mounted on the outer periphery of the driven shaft and connected to the driven shaft, a driven sprocket mounted on the outer periphery of the bearing and connected to the bearing, and a transmission chain meshing with the drive sprocket and the driven sprocket; the two ends of the main drive shaft of one of the two material transfer mechanisms are respectively connected to one end of the swing arm and one end of the transmission rod, and the main drive shaft of the other material transfer mechanism is connected to the other end of the transmission rod.

[0007] A further option is to use a one-way bearing for the aforementioned one-way rotating pair.

[0008] A further solution is: the aforementioned transmission chain is a closed-loop double-row plate chain, the transmission chain includes several chain units, and three interconnecting plates between each pair of adjacent chain units for series connection.

[0009] A further solution is as follows: The aforementioned chain unit includes a receiving seat, two pins, four chain links, and three internal connecting plates. The three internal connecting plates are pinned to the receiving seat by two pins. Two chain links are fitted on each of the four pins, and each chain link is located between two adjacent internal connecting plates. The interconnecting plate between the three units is pinned to one pin of each of two adjacent chain units that are close to each other, thereby realizing the interconnection between the chain units.

[0010] A further solution is as follows: the aforementioned support is a structural component consisting of a base frame and a panel. The base frame is an integral, inverted structural component consisting of a top plate and two connecting ears. Each of the two connecting ears has two pin holes. The panel is fixedly mounted on the upper surface of the top plate of the base frame. Two pins are engaged with the two pin holes on each of the two connecting ears of the base frame of the support.

[0011] A further option is to make the aforementioned panel a rubber sheet.

[0012] A further solution is as follows: the aforementioned storage rack includes a frame-type frame body, a boom fixedly mounted on the frame body and connected to the chain of the hydraulic hoist, and two limit rods on each side fixedly mounted on the frame body for limiting and preventing slippage of the loaded monorail to be laid; the aforementioned position sensor is installed on each of the two limit rods on the side in which the unidirectional displacement mechanism moves.

[0013] This invention has positive effects: Through its overall structural design, it enables convenient, quick, time-saving, labor-saving, and efficient material loading, storage, and unloading during the installation of monorail tracks in coal mines. This solves the problems of high manpower consumption, high labor intensity, low work efficiency, and significant safety hazards in the material storage and loading stages of existing monorail track installation processes. Furthermore, the innovative mining monorail track installation vehicle constructed using this invention provides a safe, efficient, time-saving, and labor-saving auxiliary device for monorail track installation in underground coal mines.

[0039] There is already a monorail gantry 101, and monorail 102 is yet to be laid. Detailed Implementation

[0040] The present invention will now be described in further detail with reference to the accompanying drawings and specific embodiments.

[0041] (Example 1)

[0042] See Figures 1 to 3 as well as Figure 8 The stepping feeding device (hereinafter referred to as the stepping feeding device 3) of this embodiment is used to load a certain number of monorails 102 to be laid from the ground and lift them to a set position inside the body 1 of the mining monorail hoisting track installation vehicle. During operation, it moves the monorails 102 to be laid one by one to the set position. As a specific implementation, the stepping feeding device 3 of this embodiment includes a storage rack 31 for placing the monorails 102 to be laid, a hydraulic hoist 32 connected to the storage rack 31 on the body 1 for lifting the storage rack 31, a one-way displacement mechanism 33 on the storage rack 31 for providing the monorails 102 to be laid one by one to the clamping and lifting device 4, and a position sensor 34 on the storage rack 31 for detecting whether the monorails 102 to be laid have moved into place. The stepping feeding device 3 of this embodiment can store up to 11 monorails 102 to be laid at the same time, which basically meets the installation needs of the shift.

[0043] The storage rack 31 mainly consists of a frame-type frame body 31-1, a boom 31-2 fixedly mounted on the frame body 31-1 and connected to the chain of the hydraulic hoist 32, and two limiting rods 31-3 fixedly mounted on both sides of the frame body 31-1 for limiting and preventing slippage of the loaded monorail 102 to be laid. The aforementioned position sensor 34 is installed on each of the two limiting rods 31-3 on the side in which the unidirectional displacement mechanism 33 moves, and is used to monitor whether the monorail 102 to be laid has moved into place. The one-way shifting mechanism 33 mainly consists of a shifting drive cylinder 33-1 fixed on the vehicle body 1, a swing rod 33-2 connected to the shifting drive cylinder 33-1, and two sets of identical material transfer mechanisms 33-3 driven by the swing rod 33-2 and transmitted by the transmission rod 33-4. The first set of the shifting drive cylinder 33-1 that is close to the first set of material transfer mechanisms 33-3 is directly driven by the swing rod 33-2, and the second set is transmitted by the transmission rod 33-4 and moves synchronously with the first set of material transfer mechanisms 33-3.

[0044] See Figures 4 to 7 The material transfer mechanism 33-3 is a stepping unidirectional motion mechanism. The material transfer mechanism 33-3 includes a main drive shaft 33-3-1 rotatably mounted on the frame 31-1, a unidirectional rotary joint 33-3-2 located on the outer periphery of the main drive shaft 33-3-1 and connected to it, and a drive sprocket 33-3-3 located on the outer periphery of the unidirectional rotary joint 33-3-2 and connected to it. The system includes a driven shaft 33-3-4 rotatably mounted on the frame 31-1; a bearing 33-3-5 located on the outer periphery of the driven shaft 33-3-4 and drivingly connected to it; a driven sprocket 33-3-6 located on the outer periphery of the bearing 33-3-5 and drivingly connected to it; and a closed-loop transmission chain 33-3-7 meshing with the driving sprocket 33-3-3 and the driven sprocket 33-3-6. The two ends of the main drive shaft 33-3-1 of the first material transfer mechanism 33-3 are drivingly connected to the swing arm 33-2 and the transmission rod 33-4, respectively. One end of the main drive shaft 33-3-1 of the second material transfer mechanism 33-3 is drivingly connected to the transmission rod 33-4. The one-way rotating pair 33-3-2 can be a one-way bearing or a ratchet and pawl structure, preferably a one-way bearing.

[0045] See Figures 5 to 7In this embodiment, the transmission chain 33-3-7 preferably adopts a closed-loop double-row plate chain. As a specific implementation, the transmission chain 33-3-7 includes several chain units, with three inter-unit interconnecting plates 33-3-7-5 respectively arranged between every two adjacent chain units. Each chain unit is sequentially connected through the inter-unit interconnecting plates 33-3-7-5. Each chain unit includes a receiving seat 33-3-7-1, two pins 33-3-7-2, four chain links 33-3-7-3, and three internal connecting plates 33-3-7-4. 33-3-7-4 is pinned to the receiving seat 33-3-7-1 via two pins 33-3-7-2. Two of the four links 33-3-7-3 are fitted onto each of the pins 33-3-7-2, and each link 33-3-7-3 is located between the connecting plates 33-3-7-4 of two adjacent units. The interconnecting plate 33-3-7-5 between the three units is pinned to one of the pins 33-3-7-2 of each of the two adjacent chain units, thereby realizing the series connection of the chain units.

[0046] The receiving seat 33-3-7-1 is a structural component consisting of a base frame 33-3-7-1-1 and a panel 33-3-7-1-2. The base frame 33-3-7-1-1 is an integral, inverted U-shaped structure consisting of a top plate and two connecting ears. Each of the two connecting ears has two pin holes. The panel 33-3-7-1-2 is fixedly mounted on the upper surface of the top plate of the base frame 33-3-7-1-1. The two pins 33-3-7-2 are engaged with the two pin holes on each of the two connecting ears of the base frame of the receiving seat 33-3-7-1. Preferably, the panel 33-3-7-1-2 is made of a high-friction rubber plate to prevent slippage when supporting the monorail 102 to be laid.

[0047] The principle and process of the unidirectional material transfer mechanism 33 is as follows: When the power output end (i.e., piston rod) of the displacement drive cylinder 33-1 extends, the drive rocker arm 33-2 drives the main drive shaft 33-3-1 of the material transfer mechanism 33-3 to rotate clockwise. The unidirectional rotary pair 33-3-2 only transmits clockwise rotation. At this time, the drive sprocket 33-3-3 rotates clockwise, and the transmission chain 33-3-7 also rotates clockwise, driving each monorail 102 placed on the transmission chain 33-3-7 to move in the direction of the drive sprocket 33-3-3. After one working stroke of the displacement drive cylinder 33-1, if the two position sensors 34 do not detect that any monorail 102 has reached the set position, When the piston rod of the displacement drive cylinder 33-1 retracts and drives the swing arm 33-2 to rotate counterclockwise, although the main drive shaft 31-1 rotates, the drive sprocket 33-3-3 does not rotate due to the presence of the one-way rotating pair 33-3-2. Correspondingly, the transmission chain 33-3-7 remains stationary, and the monorails 102 placed on the transmission chain 33-3-7 do not move. When the piston rod of the displacement drive cylinder 33-1 extends again, it drives the swing arm 33-2 to rotate clockwise until the position sensor 34 detects that a monorail 102 has reached the set position. Then the displacement drive cylinder 33-1 stops. This process is repeated to achieve step-by-step delivery of each monorail 102 to the set position.

[0048] As can be seen from the foregoing, the stepping feeding device 3 of this embodiment, through its overall structural design, can conveniently, quickly, efficiently, and effectively perform material feeding, storage, and discharge during the installation of monorail tracks in coal mines. This solves the problems of high manpower consumption, high labor intensity, low work efficiency, and significant safety hazards in the material storage and feeding stages of monorail track installation in the prior art.

[0052] The self-propelled device 2 is used to drive the mine monorail installation vehicle of this embodiment to run on the existing monorail track 101 to the construction point for extending the track. The self-propelled device 2 includes a walking drive mechanism 21 and a carrying trolley 22 mounted on the vehicle body 1 and dynamically connected to the existing monorail track 101 in the coal mine. The walking drive mechanism 21 and the carrying trolley 22 are both mature existing technologies and will not be described in detail.

[0053] See Figures 10 to 12 The clamping and lifting device 4 is used to clamp the monorails 102 to be laid one by one from the same position on the stepping feeding device 3 and lift them upward to the set position. The clamping and lifting device 4 mainly consists of a first clamping mechanism 41 for clamping the monorails 102 to be laid and a lifting mechanism 42 for lifting the monorails 102 to be laid held by the first clamping mechanism 41 to the set position.

[0054] See Figure 11 and Figure 12 The first clamping mechanism 41 includes two parallel vertical arms 41-1 fixedly connected to each other, a horizontal arm 41-2 fixedly connected to the upper middle part of the two vertical arms 41-1 on the same side and serving as an upper clamping member, a first clamping cylinder 41-3 fixedly disposed between the two vertical arms 41-1, a rotating arm 41-4 pinned to the power output end of the first clamping cylinder 41-3 and the two vertical arms 41-1 respectively, a first clamping arm 41-5 pinned to the rotating arm 41-4, and a first guide rail seat 41-6 fixedly disposed on the upper outer side of each of the two vertical arms 41-1. A chain connector 41-2-1 is provided in the middle of the horizontal arm 41-2. During operation, driven by the first clamping cylinder 41-3 and driven by the rotating arm 41-4, the first clamping arm 41-5 rotates to a position opposite to the lower end face of the cross arm 41-2, and the monorail 102 to be laid is clamped between the end face of the first clamping arm 41-5 and the lower end face of the cross arm 41-2.

The lifting frame 42-1 consists of a horizontal section and two vertical rods fixedly connected to the horizontal section; one first linear guide rail 42-2 is fixedly installed on the inner side of each of the two vertical rods of the lifting frame 42-1; the lifting cylinder 42-3 is fixedly installed on the horizontal section of the lifting frame 42-1; the moving sprocket 42-4 is rotatably mounted on the power output end of the lifting cylinder 42-3; the guide sprocket 42-5 is rotatably mounted on the horizontal section of the lifting frame 42-1; one end of the lifting chain 42-6 is connected to the lifting frame 42-1. The horizontal part of the lifting frame 42-1 is fixedly connected. The other end of the lifting chain 42-6 passes sequentially around the moving sprocket 42-4 and the guide sprocket 42-5 and then is fixedly connected downward to the chain connector 41-2-1 located in the middle of the horizontal arm 41-2 of the first clamping mechanism 41. The two first guide rail seats 41-6 of the first clamping mechanism 41 cooperate with the two first linear guide rails 42-2 of the lifting mechanism 42 to form two sets of linear motion pairs, thereby realizing the dynamic connection between the first clamping mechanism 41 and the lifting mechanism 42. Two second guide rail seats 42-7 are provided on the horizontal part of the lifting frame 42-1. The second guide rail seats 42-7 are used for dynamic connection with the translation device 5.

[0056] See Figure 13 and Figure 14 The translation device 5 is used to translate the monorail 102 to be laid, which has been clamped and lifted into place by the clamping and lifting device 4, to a set position. In one specific embodiment, the translation device 5 mainly consists of two translation support beams 51 fixedly installed inside the upper part of the vehicle body 1, a second linear guide rail 52 fixedly installed on the lower end surface of each of the two translation support beams 51, and a translation cylinder 53 fixedly installed on the vehicle body 1 with its power output end fixedly connected to the transverse part of the lifting frame 42-1 of the lifting mechanism 42 of the clamping and lifting device 4. The two second guide rail seats 42-7 of the lifting mechanism 42 cooperate with the two second linear guide rails 52 of the translation device 5 to form two sets of linear motion pairs, thereby realizing the dynamic connection between the translation device 5 and the clamping and lifting device 4.

[0057] See Figure 15-17 as well as Figure 8 and Figure 10 The feeding and lifting device 6 is used to clamp the monorail 102 to be laid, which is conveyed by the clamping and lifting device 4, and send it to a set position outside the vehicle body 1. It also lifts the monorail 102 to be laid to an installation position that connects with the end of the existing monorail hoisting track 101. As a specific embodiment, in this embodiment, the feeding and lifting device 6 mainly consists of a telescopic feeding mechanism 61, a lifting mechanism 62, and a second clamping mechanism 63.

[0058] The telescopic feeding mechanism 61 mainly consists of a support base 61-1 fixedly installed inside the vehicle body 1 and a telescopic arm 61-2 fixedly installed on the support base 61-1. The telescopic arm 61-2 includes a base arm 61-2-1, a primary telescopic arm 61-2-2 telescopically installed inside the base arm 61-2-1, a secondary telescopic arm 61-2-3 telescopically installed inside the primary telescopic arm 61-2-2, and a telescopic hydraulic cylinder (not shown in the figure) installed inside the telescopic arm 61-2.

When the power output end of the lifting cylinder 62-2 is extended, the first lifting frame 62-3 and the second lifting frame 62-4 are in a horizontal position; when the power output end of the lifting cylinder 62-2 is retracted, the first lifting frame 62-3 and the second lifting frame 62-4 are in a lifted position.

[0060] The second clamping mechanism 63 includes an installation connecting frame 63-1 that is pinned to the other ends of the first lifting frame 62-3 and the second lifting frame 62-4 of the lifting mechanism 62, two clamping blocks 63-2 and two clamping support arms 63-3 fixedly mounted on the installation connecting frame 63-1, a second clamping cylinder 63-4 fixedly mounted between the two clamping support arms 63-3, and a second clamping arm 63-5 driven by the power output end of the second clamping cylinder 63-4 and cooperating with the two clamping blocks 63-2 to clamp the monorail 102 to be laid.

[0061] The manual assistance platform 7 is used to carry personnel to the end of the monorail 102 to be laid, which is lifted into position, and to connect and fix the monorail 102 to the end of the existing monorail hoisting track 101. In one specific embodiment, the manual assistance platform 7 includes a personnel carrier 71, a telescopic arm 72 for adjusting the distance between the personnel carrier 71 and the vehicle body 1, a swing cylinder 73 for laterally adjusting the position of the personnel carrier 71, an amplitude-adjusting cylinder 74 for vertically adjusting the position of the personnel carrier 71, and a leveling cylinder 75 for leveling the personnel carrier 71, to facilitate construction work by personnel on the manual assistance platform 7. It should be noted that the position of the manual assistance platform 7 and the material feeding and lifting device 6 are not on the same axis as the vehicle body 1, and the two do not interfere with each other during operation.

[0062] The power assembly 8 is fixedly installed inside the vehicle body 1. The power assembly 8 is used to provide the various power required by the mining monorail hoist rail installation vehicle of this embodiment, including each oil pump. The power assembly 8 is a mature existing technology in the field of monorail hoists, and its specific structure and working principle will not be described in detail.

[0063] The working process of the mining monorail track installation vehicle in this embodiment is briefly described below:

[0064] 1. Loading: Using its self-propelled device 2, it runs on the existing monorail 101 in the coal mine to the location where there are monorails 102 to be laid, which is the loading point. The hydraulic hoist 32 of the stepping feeding device 3 lowers the storage rack 31 to the ground. After loading several (up to 11 in this embodiment) monorails 102 to be laid on the storage rack 31, the hydraulic hoist 32 lifts the storage rack 31 loaded with monorails 102 to be laid to the set position inside the vehicle body 1, thus completing the loading action.

[0065] 2. Single monorail to be laid 102 clamping and lifting: After the first clamping mechanism 41 of the clamping and lifting device 4 clamps the monorail to be laid 102 from the same position of the stepping feeding device 3 (after the previous monorail is clamped away, the next monorail to be laid 102 is transported to the position of the previous monorail to be laid 102 that was clamped away by the one-way shifting mechanism 33 of the stepping feeding device 3), the lifting mechanism 42 of the clamping and lifting device 4 lifts the clamped monorail to be laid 102 upward to the set position.

[0066] 3. Position translation of the monorail to be laid 102: The translation device 5 drives the clamping lifting device 4 to move in parallel, so that the monorail to be laid 102 held by the clamping lifting device 4 runs to the set position above the feeding lifting device 6.

[0067] 4. Clamping and conversion of the monorail to be laid 102: After the second clamping mechanism 63 of the feeding lifting device 6 clamps the monorail to be laid 102, the first clamping mechanism 41 of the clamping lifting device 4 releases the clamping of the monorail to be laid 102, thus completing the clamping and conversion of the monorail to be laid 102.
