Anti-explosion monorail hoist capable of preventing flywheel

Abstract

This invention relates to the field of monorail crane technology, and discloses an explosion-proof monorail crane capable of preventing runaway. It includes a crane box with a groove on its top. A drive and shock-absorbing mechanism is fixed within the groove and movably connected to a track. The top of the track has mounting holes. This explosion-proof monorail crane achieves both runaway prevention and shock absorption. A second roller acts as the drive, moving the crane box, while a first roller rolls within the bottom of the track. The combined use of the first and second rollers makes the crane box movement more stable, effectively preventing runaway. When the first roller rolls, the movable frame slides upwards under the action of a damper and a second spring. A third spring and a stop plate support the movable frame. The damper provides shock absorption, effectively reducing the swaying of the crane box.

Description

Technical Field

[0001] This invention relates to the field of monorail crane technology, specifically to an explosion-proof monorail crane capable of preventing runaway. Background Technology

[0002] In special situations such as coal mine roadways, highway tunnels, and railway tunnels, monorail cranes are frequently used to transport goods and personnel. The main advantages of monorail crane transportation are: first, the monorail crane itself has a small cross-section, resulting in high utilization of roadway cross-sectional space; second, it can be used for continuous non-transfer transportation in horizontal and inclined roadways, and its transport load is not limited by the floor conditions, allowing it to operate on various vertical curves, horizontal curves, and complex curves; third, it can complete auxiliary transportation from the mining area yard to the working face without transfer, and can be used for auxiliary transportation operations connecting the main transport roadways and mining area roadways. Explosion-proof monorail cranes have explosion-proof characteristics and high safety.

[0003] The existing monorail cranes have a less than smooth ride, and the connection between the crane and the rails is not tight enough, which can easily lead to runaway. The crane is also prone to bumping and shaking during travel, and excessive shaking can cause the material inside to spill out. When traveling on curves or slopes, the crane is prone to rolling backward, which affects the material conveying efficiency. Therefore, an explosion-proof monorail crane that can prevent runaway is proposed to solve the above problems. Summary of the Invention

[0004] The purpose of this invention is to provide an explosion-proof monorail crane that can prevent runaway, in order to solve the problems mentioned in the background art, such as the uneven movement of the gantry in existing monorail cranes, the insufficient tightness of the connection between the gantry and the rail, which easily leads to runaway, the gantry being prone to bumping and shaking during travel, and the leakage of materials due to excessive shaking, and the gantry being prone to backtracking when traveling on curves or slopes, which affects the material conveying efficiency.

[0005] To achieve the above objectives, the present invention provides the following technical solution: an explosion-proof monorail crane capable of preventing runaway vehicles, comprising a crane box, the top of which has a groove, a drive and shock absorption mechanism fixed in the groove, the drive and shock absorption mechanism being movably connected to a track, and the top of the track having mounting holes.

[0006] Preferably, the driving and damping mechanism includes a first motor, which is fixed in the groove. The output end of the first motor is connected to a first rotating shaft, and a first chain drive device is symmetrically fixed at both ends of the first rotating shaft.

[0007] By adopting the above technical solution, the rotation of the first rotating shaft can drive the two first chain drive devices to operate.

[0008] Preferably, brackets are symmetrically fixed on both sides of the upper surface of the hoisting box, and a first spring is fixed on the inner wall of the bracket. A tension wheel is fixed to the inner end of the first spring, and the tension wheel is in close contact with the rear inner wall of the first chain drive device.

[0009] By adopting the above technical solution, the tensioning wheel tensions the chain on the first chain drive device.

[0010] Preferably, a fixed frame is fixed at the middle of the upper surface of the hoisting box, and the lower side of the top of the fixed frame is connected to the movable frame through a damper. A second spring is wrapped around the outside of the damper. The movable frame passes through the top of the fixed frame and the bottom of the track, and a second rotating shaft is rotatably connected to the top of the movable frame. First rollers are symmetrically fixed at both ends of the second rotating shaft, and the first rollers are placed inside the track.

[0011] By adopting the above technical solution, the rotation of the first roller can help the hoisting box move stably.

[0012] Preferably, the upper side of the movable frame is connected to the back plate via a third spring, and the upper end face of the back plate and the outer end face of the first roller are both movably connected with ball bearings.

[0013] By adopting the above technical solution, the ball bearing can reduce friction.

[0014] Preferably, a support frame is symmetrically fixed on both sides of the upper surface of the fixed frame, and a third rotating shaft is rotatably connected to the support frame. A rotating block is fixed to the outer end of the third rotating shaft, and the rotating block is connected to the output end of the first chain drive device. A slot is opened on the outer side of the rotating block, and the slots are evenly distributed circumferentially on the rotating block. A second roller is fixed to the inner end of the third rotating shaft, and the second roller rests on the track.

[0015] By adopting the above technical solution, the rotation of the second roller can drive the hoisting box to move.

[0016] Preferably, a reversing mechanism is fixed in the groove, and the reversing mechanism extends into the support frame and is engaged in the slot. The reversing mechanism includes a second motor, and the second motor is fixed in the inner top of the groove. The output end of the second motor is connected to the second chain drive device, and rotating columns are symmetrically fixed on both sides of the upper surface of the second chain drive device.

[0017] By adopting the above technical solution, the operation of the second chain drive device can drive the rotating column to rotate.

[0018] Preferably, the rotating column passes through the top of the hanging box and is engaged with a square column, and a connecting shaft is fixed to the top of the square column. A sleeve is fixed inside the support frame, and the upper side of the bottom of the sleeve is connected to a washer through a fourth spring. The washer is slidably connected inside the sleeve. The connecting shaft passes through the bottom of the sleeve and the washer and is connected to a locking block, and the locking block is engaged in a slot.

[0019] By adopting the above technical solution, when the rotating block rotates, the card block will automatically lock into the card slot, which can prevent the rotating block from rotating back.

[0020] Preferably, a limiting ring is fixed to the bottom of the card block, and the limiting ring is rotatably connected to the upper end surface of the pad ring.

[0021] By adopting the above technical solution, the limiting ring serves to connect the locking block and the washer ring.

[0022] Compared with the prior art, the beneficial effects of the present invention are: this explosion-proof monorail crane can prevent runaway vehicles.

[0023] (1) The present invention can achieve the purpose of preventing runaway and shock absorption. The second roller is used as a driving roller to drive the hoisting box to move. At the same time, the first roller rolls inside the bottom of the track. The combination of the first roller and the second roller can make the hoisting box move more stably and effectively prevent runaway. When the first roller rolls, the movable frame can slide up under the action of the damper and the second spring. The combination of the third spring and the abutment plate can support the movable frame. The damper can play the role of shock absorption and can effectively reduce the degree of swaying of the hoisting box.

[0024] (2) The present invention can achieve the purpose of preventing backing up. The fourth spring plays a supporting role on the pad ring. When the rotating block rotates, the card block will automatically be locked into the card slot. Since one side of the card block is tilted, the rotating block cannot rotate back. This can effectively prevent the hoist box from backing up. Before returning to the hoist box, the second chain drive device operates, thereby driving the rotating column, square column, connecting shaft and card block to rotate 180 degrees, which makes it convenient to change the direction of the card block.

[0025] (3) The present invention can achieve the purpose of preventing detachment. During the movement of the hoisting box, the first chain drive device will sway up and down with the hoisting box. With the use of the first spring and tension wheel, the chain on the first chain drive device can always be tensioned, so as to prevent the chain on the first chain drive device from being too loose and detaching from the sprocket.

Detailed Implementation

[0036] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0037] Please see Figure 1-9 This invention provides a technical solution: an explosion-proof monorail crane capable of preventing runaway vehicles, such as... Figure 1-9As shown, the device includes a hanging box 1, with a groove 2 on the top of the hanging box 1. A drive and shock absorption mechanism 3 is fixed in the groove 2. The drive and shock absorption mechanism 3 is movably connected to the track 4. The drive and shock absorption mechanism 3 includes a first motor 301, which is fixed in the groove 2. The output end of the first motor 301 is connected to a first rotating shaft 302. First chain drive devices 303 are symmetrically fixed at both ends of the first rotating shaft 302. The first rotating shaft 302 can rotate under the action of the first motor 301, thereby driving the two first chain drive devices 303 to operate.

[0038] Furthermore, brackets 304 are symmetrically fixed on both sides of the upper surface of the hoisting box 1, and a first spring 305 is fixed on the inner wall of the bracket 304. A tension wheel 306 is fixed to the inner end of the first spring 305, and the tension wheel 306 is in close contact with the rear inner wall of the first chain drive device 303. The tension wheel 306 will press against the first chain drive device 303 under the supporting action of the first spring 305, so that the chain on the first chain drive device 303 can always be kept in a taut state.

[0039] Furthermore, a fixed frame 307 is fixed at the middle of the upper surface of the hanging box 1, and the lower side of the top of the fixed frame 307 is connected to the movable frame 310 through a damper 308. A second spring 309 is wrapped around the outside of the damper 308. The movable frame 310 passes through the top of the fixed frame 307 and the bottom of the track 4, and a second rotating shaft 311 is rotatably connected to the top of the movable frame 310. First rollers 312 are symmetrically fixed at both ends of the second rotating shaft 311, and the first rollers 312 are placed in the track 4. When the first rollers 312 roll in the bottom of the track 4, the movable frame 310 can slide up and down in the fixed frame 307. The damper 308 and the second spring 309 provide support for the movable frame 310, which facilitates the effect of shock absorption.

[0040] Furthermore, the upper side of the movable frame 310 is connected to the abutment plate 314 via a third spring 313, and both the upper end face of the abutment plate 314 and the outer end face of the first roller 312 are movably connected with balls 315. When the first roller 312 rolls in the track 4, the third spring 313 and the abutment plate 314 work together to support the first roller 312. The balls 315 on the first roller 312 can reduce the friction between the first roller 312 and the track 4, and the balls 315 on the abutment plate 314 can reduce the friction between the abutment plate 314 and the track 4, making the movement of the first roller 312 and the abutment plate 314 as a whole smoother.

[0041] Furthermore, support frames 316 are symmetrically fixed on both sides of the upper surface of the fixed frame 307, and a third rotating shaft 317 is rotatably connected to the support frame 316. A rotating block 318 is fixed to the outer end of the third rotating shaft 317, and the rotating block 318 is connected to the output end of the first chain drive device 303. A slot 319 is opened on the outer side of the rotating block 318, and the slot 319 is evenly distributed circumferentially on the rotating block 318. A second roller 320 is fixed to the inner end of the third rotating shaft 317, and the second roller 320 is placed on the track 4. The operation of the first chain drive device 303 can drive the rotating block 318 to rotate, thereby driving the third rotating shaft 317 and the second roller 320 to rotate. The second roller 320 rolls on the track 4, which facilitates the movement of the hoisting box 1.

[0042] Furthermore, a reversing mechanism 321 is fixed inside the groove 2, and the reversing mechanism 321 extends into the support frame 316 and is engaged in the slot 319. The reversing mechanism 321 includes a second motor 3211, and the second motor 3211 is fixed to the inner top of the groove 2. The output end of the second motor 3211 is connected to the second chain drive device 3212, and rotating columns 3213 are symmetrically fixed on both sides of the upper end face of the second chain drive device 3212. The second chain drive device 3212 can operate under the action of the second motor 3211, thereby driving the rotating columns 3213 to rotate.

[0043] Furthermore, the rotating column 3213 penetrates the top of the hanging box 1 and is engaged with a square column 3214. A connecting shaft 3215 is fixed to the top of the square column 3214. A sleeve 3216 is fixed inside the support frame 316. The upper side of the bottom of the sleeve 3216 is connected to a washer 3217 via a fourth spring 3218. The washer 3217 is slidably connected inside the sleeve 3216. The connecting shaft 3215 penetrates the bottom of the sleeve 3216 and the washer 3217 and is connected to a locking block 3219. The locking block 3219 is engaged in the slot 319. The rotation of the rotating column 3213 can drive the square column 3214, the connecting shaft 3215 and the locking block 3219 to rotate, making it easy to change the direction of the locking block 3219. The fourth spring 3218 provides support for the washer ring 3217. When the rotating block 318 rotates, the locking block 3219 will automatically spring into the slot 319. Since one side of the locking block 3219 is tilted, the rotating block 318 can only rotate in one direction, which can effectively prevent the hoisting box 1 from moving backward.

[0044] In addition, a limiting ring 32110 is fixed at the bottom of the locking block 3219, and the limiting ring 32110 is rotatably connected to the upper end face of the washer ring 3217. The limiting ring 32110 serves to connect the locking block 3219 and the washer ring 3217. The washer ring 3217 does not rotate, but the locking block 3219 and the limiting ring 32110 can rotate relative to the washer ring 3217.

[0045] like Figure 1As shown, the top of the track 4 has a mounting hole 5, which can be fixed in the required location by the mounting hole 5 and external bolts, making installation convenient.

[0046] Working principle: When using this explosion-proof monorail crane that prevents runaway, the track 4 is first installed at the required location using the mounting holes 5 and external bolts. The first rotating shaft 302 rotates, thereby driving the first chain drive device 303 to rotate, which in turn drives the rotating block 318, the third rotating shaft 317, and the second roller 320 to rotate, thereby driving the hoisting box 1 to move. The first spring 305 and the tension wheel 306 are used to support the chain on the first chain drive device 303. The first roller 312 rolls inside the bottom of the track 4, and the second spring 309 and the third spring 313 support the movable frame 310. The damper 308 acts as a support when the hoisting box 1 is bumpy, and when the rotating block 318 rotates, the locking block 3219 automatically locks into the locking slot 319, preventing the rotating block 318 from rotating back. After the hoisting box 1 moves to the end in one direction, the second chain drive device 3212 operates, thereby driving the rotating column 3213 to rotate. The square column 3214, the connecting shaft 3215, and the locking block 3219 rotate 180 degrees. When the hoisting box 1 returns, the rotating block 318 can only rotate in the corresponding direction and cannot rotate back.
