Description

Technical Field

[0001] The present invention belongs to the technical field of auxiliary transportation equipment in coal mines, and specifically relates to an electric single rail hoist locomotive. Background Art

[0002] The coal industry is a pillar industry in China. Developing energy-saving, environmentally friendly, efficient and fast auxiliary transportation methods is an important task in the construction of China's coal mine industry. The single rail hoist system is an important auxiliary transportation system in coal mines. The single rail hoist locomotive is a modern aerial transportation equipment in coal mines. The I-beam single rail, that is, the I-shaped track, is suspended from the top of the roadway by a round link chain. The locomotive travels back and forth on the single rail for transportation, which has the advantages of convenience, speed and large transportation volume. The traditional single rail hoist locomotive uses an explosion-proof diesel engine as the power and is hydraulically driven. The problems are serious exhaust gas pollution and noise pollution from the engine, which are difficult problems that cannot be solved in the working conditions of coal mine roadways.

[0003] With the application of new scientific and technological in the coal mine industry and the construction of safe, high-yield and efficient modern coal mines, the electric single rail hoist locomotive system has various advantages such as safety, energy saving and environmental protection, which has great practical significance for improving the working conditions of coal mine workers and enhancing the level of safe production. At the same time, for the normal operation of the electric single rail hoist locomotive, in addition to solving a series of technologies such as the power drive device, transmission system, and hydraulic control system, it is necessary to carry a motor frequency conversion control device and a battery device on the vehicle. The outer dimensions of these devices are relatively long, and it is easy to get stuck when passing through track curves and slopes. At the same time, the battery capacity directly affects the endurance mileage of the locomotive. At present, for safety reasons in China's coal mine industry, charging is not allowed in coal mine shafts. The endurance mileage of the locomotive can be improved by replacing the battery, and it is very necessary to develop a fast replacement function for the battery cabinet.

Detailed implementation manners

[0048] To enable those skilled in the art to better understand the technical solution of the present invention, the technical solution of the present invention will be clearly and completely described below in conjunction with the accompanying drawings of the present invention. Based on the embodiments in this application, other similar embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the scope of protection of this application.

[0049] As Figure 1 shown, the electric monorail hoist locomotive provided in this specific embodiment includes a cab, a personnel compartment cabinet, a battery cabinet for installing a battery pack, a frequency conversion cabinet for installing a motor frequency conversion control device, a cab suspension device for suspending the cab, a personnel compartment cabinet suspension device for suspending the personnel compartment cabinet, a load suspension device for suspending the load, two mutually hinged cabinet suspension devices, and a plurality of sequentially hinged drive devices. The structure of the personnel compartment cabinet suspension device is the same as that of the cabinet suspension device. The cab suspension device and the load suspension device are arranged at both ends of the electric monorail hoist locomotive. One of the drive devices at the end is hinged to the load suspension device, and the drive device at the other end is hinged to the personnel compartment cabinet suspension device. One of the cabinet suspension devices is hinged to the personnel compartment cabinet suspension device, and the other cabinet suspension device is hinged to the cab suspension device. Of course, the positions of the cab, the personnel compartment cabinet, the battery cabinet, the frequency conversion cabinet, the drive device, and the load suspension device can be arranged arbitrarily, and are not limited to the arrangement disclosed in this specific embodiment.

[0050] As Figure 7 shown, the drive device 3000 of the electric monorail hoist locomotive provided in this specific embodiment includes a drive frame 100, a drive wheel mechanism provided on the drive frame 100 for driving the monorail hoist locomotive to run, a first load-bearing wheel assembly 300 for suspending the drive device 3000 on the I-shaped track 500, and a first braking mechanism for braking the drive device. The drive wheel mechanism includes two relatively arranged drive wheel assemblies 200. The first braking mechanism includes two relatively arranged braking assemblies 400. The first load-bearing wheel assembly 300 is provided with 2. The drive wheel mechanism is arranged between the two first load-bearing wheel assemblies 300. The first braking mechanism is arranged on one side of one of the first load-bearing wheel assemblies 300 away from the drive wheel mechanism, that is, one of the first load-bearing wheel assemblies 300 is arranged between the first braking mechanism and the drive wheel mechanism.

[0051] As Figures 2 - 6As shown, the drive frame includes a drive frame longitudinal beam 123, a drive wheel assembly mounting seat, a first carrier wheel mounting seat 111, and a brake carrier mechanism mounting seat for mounting a first braking mechanism and a first carrier wheel assembly, which are arranged on the drive frame longitudinal beam 123. The drive frame longitudinal beam 123 is a plate-like structure, and the drive frame is axially symmetrically distributed along the drive frame longitudinal beam 123. The drive frame longitudinal beam 123 is placed vertically, and the first carrier wheel mounting seat 111 and the brake carrier mechanism mounting seat are respectively connected to the two longitudinal ends of the drive frame longitudinal beam 123.

[0052] The drive wheel assembly mounting seat includes an upper mounting plate 121 and a lower mounting plate 122. The upper mounting plate 121 is connected to the upper end of the drive frame longitudinal beam 123. One longitudinal end of the upper mounting plate 121 is connected to the first carrier wheel mounting seat 111, and the other end is connected to the brake carrier mechanism mounting seat. At one end of the upper mounting plate 121 close to the first carrier wheel mounting seat 111, there are two first drive wheel mechanism mounting holes 1211 symmetrically arranged along the drive frame longitudinal beam 123 for mounting the drive wheel mechanism. On both sides of the upper mounting plate 121 between the brake carrier mechanism mounting seat and the first drive wheel mechanism mounting holes 1211, there are respectively provided relief notches for mounting the drive wheel mechanism. The structure of the upper mounting plate 121 enables the drive wheel mechanism to be mounted on the upper mounting plate 121 and makes the structure of the drive frame compact. The lower mounting plate 122 is arranged at the lower end of the drive frame longitudinal beam 123 and is oppositely arranged longitudinally with one end of the upper mounting plate 121 close to the first carrier wheel mounting seat 111. The size of the lower mounting plate 122 is the same as that of the upper mounting plate 121 between the first carrier wheel mounting seat 111 and the relief notch. There are two second drive wheel mechanism mounting holes 1221 symmetrically arranged along the drive frame longitudinal beam 123 on the lower mounting plate 122. The two second drive wheel mechanism mounting holes 1221 are respectively arranged corresponding to the two first drive wheel mechanism mounting holes 1211. The cooperation of the upper mounting plate 121 and the lower mounting plate 122 enables the drive wheel mechanism to be rotatably mounted at the first drive wheel mechanism mounting holes 1211 and the second drive wheel mechanism mounting holes 1221 through a pin shaft, realizing the adjustable distance between the drive wheel of the drive device and the web of the I-shaped track 500 of the single-track crane, so that the drive frame can be applicable to different I-shaped tracks 500 of the single-track crane, and realizing the adjustable friction between the drive wheel of the drive device and the I-shaped track 500 of the single-track crane. The smaller the distance between the drive wheel of the drive device and the web of the I-shaped track 500 of the single-track crane, the greater the friction between the drive wheel of the drive device and the I-shaped track 500 of the single-track crane, and it can carry and transport heavier items.

[0053] The brake bearing mechanism mounting seat includes a first brake mechanism mounting seat 131, a second carrier wheel mounting seat 112, and a connecting plate 132 connected to the end of the driving frame longitudinal beam 123.

The upper end of the driving frame longitudinal beam 123 is vertically connected to the upper mounting plate 121. The upper mounting plate 121 is connected between the first carrier wheel mounting seat 111 and the connecting plate 132. The first brake mechanism mounting seat 131 and the second carrier wheel mounting seat 112 are connected to the upper mounting plate 121. The first brake mechanism mounting seat 131 is arranged between the connecting plate 132 and the second carrier wheel mounting seat 112. Since the driving frame longitudinal beam 123 is erected, the upper mounting plate 121 is used to mount the driving wheel mechanism on the one hand and provides a setting site for the first brake mechanism mounting seat 131 and the second carrier wheel mounting seat 112 on the other hand, improving the compact structure of the driving frame, minimizing unnecessary components, and reducing the weight of the driving frame.

[0054] The first brake mechanism mounting seat 131 includes two symmetrically distributed first mounting plates 1311 and second mounting plates 1312. First brake mechanism mounting holes 1313 for mounting the first brake mechanism are provided on both the first mounting plate 1311 and the second mounting plate 1312. The lower ends of the first mounting plate 1311 and the second mounting plate 1312 are both connected to the upper mounting plate 121. The two ends of the first mounting plate 1311 and the second mounting plate 1312 are respectively connected to the upper end of the connecting plate 132 and the second carrier wheel mounting seat 112.

[0055] The upper end of the first carrier wheel mounting seat 111 is provided with a V-shaped structure. The lower end of the first carrier wheel mounting seat 111 is vertically connected to the driving frame longitudinal beam 123. The second carrier wheel mounting seat 112 is provided with a V-shaped structure. Carrier wheel mounting holes 113 are provided on the two opposite sides of the upper end of the V-shaped structure of the first carrier wheel mounting seat 111 and the two opposite sides of the upper end of the V-shaped structure of the second carrier wheel mounting seat 112. The axial direction of the carrier wheel mounting holes 113 is the same as the angle between the lower wing surface of the I-shaped track 500 of the single rail hoist locomotive and the horizontal plane. This setting makes the contact between the carrier wheel and the I-shaped track 500 of the single rail hoist locomotive a line contact, thereby ensuring the load-bearing capacity of the carrier wheel.

[0056] Traction connection seats 141 for connecting two adjacent driving frames are provided at both ends of the driving frame. One traction connection seat 141 is connected to the first carrier wheel mounting seat 111, and the other traction connection seat 141 is connected to the connecting plate 132. The traction connection seat 141 includes two traction plates, and pin insertion holes for inserting pins are provided on the traction plates.

[0057] Furthermore, the driving frame longitudinal beam 123, the driving wheel assembly mounting seat, the first carrier wheel mounting seat 111, the braking carrier mechanism mounting seat, and the traction connection seat 141 are of an integrally formed structure, making the appearance of the driving frame beautiful and the structure compact and delicate.

[0058] On the driving frame of the driving device 3000, there are separate mounting sites for the first carrier wheel assembly, the driving wheel mechanism, and the first braking mechanism, making it convenient to disassemble and assemble the first carrier wheel assembly, the driving wheel mechanism, and the first braking mechanism, and facilitating the maintenance or replacement of parts of the driving device of the single-track hoist locomotive.

[0059] As Figures 7 - 9 shown, the first carrier wheel assembly 300 includes two carrier wheels 310 arranged oppositely. The first carrier wheel assembly 300 is set to 2, that is, there are a total of 4 carrier wheels for the driving device. The 4 carrier wheels 310 are respectively rotatably mounted at the carrier wheel mounting holes 113 of the first carrier wheel mounting seat 111 and the second carrier wheel mounting seat 112 through the carrier wheel mounting shafts 320 and bearings 330. After the carrier wheels 310 are installed, based on the V-shaped structure of the first carrier wheel mounting seat 111 and the second carrier wheel mounting seat 112, the included angle between the axial direction of the carrier wheels 310 and the horizontal plane is the same as the included angle between the lower wing surface of the I-shaped track of the single-track hoist locomotive and the horizontal plane, realizing the line contact between the carrier wheels 310 and the I-shaped track 500 of the single-track hoist locomotive and ensuring the load-bearing capacity of the carrier wheels 310.

[0060] As Figure 4 、 7 、10 and 11 shown, the driving wheel assembly 200 includes a mechanical transmission box mounting seat 210 arranged at the relief notch of the driving wheel assembly mounting seat, a mechanical transmission box 230 connected to the mechanical transmission box mounting seat 210, and a driving wheel 240 and a driving motor 250 respectively connected to the mechanical transmission box 230. The mechanical transmission box 230 is connected to the mechanical transmission box mounting seat 210. The driving motor 250 outputs torque and transmits it to the mechanical transmission box 230. After the speed ratio of the internal gears of the mechanical transmission box 230 is changed, the power is output and transmitted to the driving wheel 240 to realize the rotation of the driving wheel 240. The driving wheel assembly 200 realizes driving the single-track hoist locomotive to travel on the I-shaped track 500 through the friction force between the driving wheel 240 and the I-shaped track 500 of the single-track hoist locomotive. The driving wheel mechanism uses the driving motor 250 as the driving force, which is green and environmentally friendly, has no exhaust gas emission pollution and little noise pollution, and well improves the working environment in the coal mine underground.

[0061] One end of the mechanical transmission box mounting seats 210 of the two drive wheel assemblies 200 is respectively arranged on the drive wheel assembly mounting seats and is hinged between the upper mounting plate 121 and the lower mounting plate 122 through a pin shaft 260. The pin shaft 260 sequentially passes through the first drive wheel mechanism mounting hole 1211, the mechanical transmission box mounting seat 210 and the second drive wheel mechanism mounting hole 1221. The other ends of the two mechanical transmission box mounting seats 210 are connected through a drive wheel pressing oil cylinder 220. The two mechanical transmission box mounting seats 210 are respectively hinged to both ends of the drive wheel pressing oil cylinder 220. A relief hole for the drive wheel pressing oil cylinder 220 to pass through is arranged on the drive frame longitudinal beam 123. The mechanical transmission box 230 is connected to the mechanical transmission box mounting seat 210. By adjusting the distance between the drive wheels 240 of the two drive wheel assemblies 200 through the expansion and contraction of the drive wheel pressing oil cylinder 220, the distance between the drive wheel 240 and the web of the I-shaped track 500 of the single rail hoist locomotive can be adjusted, so that the drive device can be applicable to different I-shaped tracks 500 of the single rail hoist locomotive, and the friction force between the drive wheel 240 and the I-shaped track 500 of the single rail hoist locomotive can be adjusted. The smaller the distance between the drive wheel 240 and the web of the I-shaped track 500 of the single rail hoist locomotive, the greater the friction force between the drive wheel 240 and the I-shaped track 500 of the single rail hoist locomotive. It can carry and transport heavier items, so that the load-bearing capacity of the single rail hoist locomotive can be adjusted. On the other hand, when the single rail hoist locomotive transports lighter items, the distance between the drive wheel 240 and the web of the I-shaped track 500 of the single rail hoist locomotive is increased, and the friction force between the drive wheel 240 and the I-shaped track 500 of the single rail hoist locomotive is reduced. At this time, the friction force received by the drive wheel 240 is small, and the wear of the drive wheel 240 is small, so that the friction force between the drive wheel 240 and the I-shaped track 500 of the single rail hoist locomotive can be adjusted, and the service life of the drive wheel 240 can be increased. Further, the two mechanical transmission box mounting seats 210 are connected through the drive wheel pressing oil cylinder 220. By controlling the distance between the drive wheel 240 and the web of the I-shaped track 500 through the drive wheel pressing oil cylinder 220, it can ensure that the drive wheels 240 on both sides of the I-shaped track 500 have the same pressing force on the web of the I-shaped track 500, and the work is reliable and safe.

[0062] Such as Figure 6 、 7As shown in FIGS. 12 and 13, the braking assemblies 400 of the two first braking mechanisms are respectively and oppositely installed at the first braking mechanism mounting holes 1313 of the driving frame 100. The braking assembly 400 includes a cylinder block and a braking rod 412 disposed within the cylinder block and axially movable along the cylinder block. The braking rod 412 includes a piston disposed within the cylinder block, and a piston rod and a mounting rod connected to both ends of the piston. The mounting rod is disposed within the cylinder block. One end of the piston rod is connected to the piston, and the other end extends out of the cylinder block. A braking shoe 415 is provided at the end of the piston rod extending out of the cylinder block. The braking shoes 415 of the two braking assemblies are disposed oppositely. A braking spring 413 is sleeved on the mounting rod. A piston seal 421 is provided between the piston and the inner wall of the cylinder block, and a piston rod seal 422 is provided between the piston rod and the inner wall of the cylinder block. The piston seal 421 and the piston rod seal 422 are provided to achieve a space seal between the piston seal 421 and the piston rod seal 422 within the cylinder block without oil leakage. An oil inlet / outlet is provided at one end of the cylinder block close to the extension of the piston rod. A tubing joint 417 is provided within the oil inlet / outlet for introducing or discharging hydraulic oil. When the single-track hoist locomotive is in operation, hydraulic oil is introduced into the cylinder block, the braking rod 412 retracts into the cylinder block, the braking spring 413 is compressed, and the braking assembly is in a non-braking state; when the single-track hoist locomotive is not in operation or braking is required, the hydraulic pump stops working, no hydraulic oil is introduced into the cylinder block, and the braking rod 412 extends outward under the action of the braking spring 413 to press the braking shoe 415 against the web of the I-shaped track 500, and the braking of the single-track hoist locomotive is achieved by relying on the friction force between the braking shoe 415 and the web of the I-shaped track 500.

[0063] Further, the two cylinder blocks of the two braking assemblies 400 are controlled by the hydraulic oil of the same pipeline, that is, the tubing joints 417 of the two cylinder blocks of the two braking assemblies 400 are connected to the same hydraulic oil pipeline. This setting ensures that the brakes on both sides can brake or release the brake simultaneously, start synchronously on both sides, and brake synchronously, with high safety performance.

[0064] An annular groove is provided at the end of the piston rod connected to the braking shoe 415. A mounting groove is provided on the braking shoe 415. One end of the braking rod 412 provided with the annular groove extends into the mounting groove of the braking shoe 415. The braking rod 412 and the braking shoe 415 are connected by a braking shoe connecting pin 416. The middle part of the braking shoe connecting pin 416 is placed within the annular groove. This setting method makes the connection between the piston rod and the braking shoe 415 more flexible, can relieve part of the torque at the braking shoe 415 during the braking of the single-track hoist locomotive, increases the service life of the piston rod and the braking shoe 415, and this setting facilitates the disassembly and assembly of the braking shoe 415, and is convenient for maintenance or replacement.

[0065] The cylinder block includes a cylinder barrel 411 and a cylinder head 414 disposed at one end of the cylinder barrel 411. The cylinder head 414 is connected to the end of the cylinder barrel 411 away from the brake shoe 415 by cylinder head fixing bolts 431. The middle part of the cylinder head 414 is inserted into the cylinder barrel 411. A relief groove for the telescopic movement of the installation rod is provided on the part of the cylinder head 414 inserted into the cylinder barrel 411. The size of the relief groove matches the size of the end of the brake rod 412 away from the brake shoe 415, that is, the size of the relief groove matches the size of the end of the installation rod away from the piston. The end of the installation rod away from the piston can axially move in the relief groove. When the braking assembly 400 is in the non-braking state, the installation rod extends into the bottom of the relief groove. When the braking assembly 400 is in the braking state, the installation rod extends outward to the notch of the relief groove under the action of the braking spring 413. This setting realizes the closure of the cylinder barrel 411 while reducing the axial length of the cylinder barrel, further reducing the volume of the braking assembly 400 and making the braking assembly 400 more compact.

[0066] Furthermore, the radial dimension of the piston is larger than that of the installation rod. The braking spring 413 is located on the installation rod between the piston and the cylinder head 414. The piston and the cylinder head 414, while playing their own roles, also limit the braking spring 413, making the operation of the braking assembly more stable, reducing the use of limit parts, simplifying the structure, reducing the processing difficulty, and facilitating disassembly and assembly.

[0067] A flange is provided at the end of the cylinder barrel 411 close to the brake shoe 415. The cylinder barrel 411 and the flange are of an integrally formed structure. The cylinder barrel 411 located between the flange and the brake shoe 415 is placed in the first braking mechanism mounting hole 1313 of the driving frame 100. Matching rabbets are provided on the flange and the driving frame 100. The flange is connected to the driving frame 100 by the rabbet connection and the braking assembly is connected to the driving frame 100 through the connection of the braking assembly fixing bolts. This connection method has strong anti-deformation ability and improves the braking ability.

Traction connecting seats for connecting the adjacent cabinet suspension devices are arranged on the fixed connecting plates. Two fixed connecting crossbeams are connected to the lower ends between the two driving suspension vertical plates. The two fixed connecting crossbeams are arranged at both ends between the two driving suspension vertical plates along the conveying direction of the single-rail hoist locomotive. The cab is connected to the middle of the fixed connecting crossbeam by bolts and nuts. Rubber buffer pads are arranged at the positions where the upper ends of the fixed connecting crossbeams are inserted with bolts, which are used to increase the shock absorption of the cab during operation and improve the comfort level.
