Description

Technical Field

[0001] The present application relates to the technical field of belt conveyor equipment, and in particular to a deviation corrector with self-limiting and automatic oiling functions. Background Art

[0002] In mine transportation systems, belt conveyors are a primary tool for transporting bulk materials. However, belt deviation is a common and difficult problem to resolve. Belt deviation can be caused by factors such as material not landing in the center of the belt cross section, improper head and tail assembly, belt joints not being perpendicular to the belt centerline, uneven belt tension, clumsy idlers, inconsistent roller wear, and material trapped between the roller and the belt. Traditional belt deviation correctors can correct the belt back to its normal operating line.

[0003] In the prior art, although the existing deviation corrector has solved the problem of belt deviation to a certain extent, it still has the following shortcomings:

[0004] 1. Frequent maintenance: Existing correctors usually require regular manual inspection and lubrication, which increases maintenance costs and downtime;

[0005] 2. Insufficient or excessive lubrication: It is difficult to accurately control the amount of lubrication by manual oiling, which may lead to insufficient lubrication (accelerated wear) or excessive lubrication (polluting materials or the environment);

[0006] In order to solve the above problems, the present invention provides a novel belt deviation corrector with self-limiting and automatic oiling functions. Summary of the Invention

[0007] The present application proposes a deviation corrector with a self-limiting and automatic oiling function. During deviation correction, the correction mechanism swings around the self-limiting stability shaft group. When the self-limiting stability shaft group swings, the one-way liquid pump is driven by the transmission part to work, so as to adaptively and real-timely pump lubricating oil into the self-limiting stability shaft group, which can not only reduce the loss of lubricating oil, but also ensure the timeliness of lubrication and reduce the cost of manpower maintenance.

[0008] To achieve the above-mentioned purpose, the present application adopts the following technical solution: a corrector with a self-limiting and automatic oiling function, comprising a supporting beam, the supporting beam being connected to a correcting mechanism through a self-limiting stability shaft group, an adaptive lubrication mechanism being provided between the self-limiting stability shaft group and the correcting mechanism, the self-limiting stability shaft group comprising a bearing sleeve, the bearing sleeve being connected to a connecting shaft through the bearing group; the adaptive lubrication mechanism comprising an oil tank, a one-way liquid pump and an induction frame, the oil tank and the one-way liquid pump being fixedly mounted on one side of the supporting beam, the induction frame being fixedly connected to the correcting mechanism, the one-way liquid pump being able to pump the lubricating oil in the oil tank into the bearing sleeve, and the lubricating oil in the bearing sleeve being returned to the oil tank, the induction frame being connected to the one-way liquid pump through a transmission member, and driving the one-way liquid pump to work when the induction frame swings around the self-limiting stability shaft group.

[0009] Furthermore, the mounting mechanism is provided with two groups, and the two groups of mounting mechanisms are respectively arranged on both sides of the supporting beam.

A row of holes is provided on the telescopic frame, and the adjusting mounting frame is fixedly connected to the telescopic frame through bolts, and the bolts pass through the row of holes. A height adjustment rod is provided on the top of the adjusting mounting frame, and the height adjustment rod passes through the connecting block.

[0010] Furthermore, the bearing group includes two groups of thrust ball bearings and one group of needle roller bearings. The needle roller bearings are located in the middle of the two groups of thrust ball bearings. The top of the bearing group is encapsulated by a shaft cover and a shaft with an elastic retaining ring, and the connecting shaft is fixed by a stop washer and a round nut.

[0011] Furthermore, the lower end of the bearing sleeve is connected to a dust cover. Keyways are milled on both the dust cover and the connecting shaft, and the dust cover and the connecting shaft are keyed together. The bearing sleeve is provided with a limit block, and the dust cover is provided with a limit groove corresponding to the limit block. The limit block and limit groove cooperate to limit the maximum rotation angle of the connecting shaft. The limit structure is built into the correction mechanism, which has strong applicability and eliminates the problems of on-site spatial structure interference and material clogging of the external limit mechanism. At the same time, due to the high machining precision, the limit effect is more easily guaranteed.

[0012] Furthermore, the correction mechanism includes a roller bracket, which is welded to the end of the connecting shaft. The roller bracket is provided with rollers, and there are three groups of rollers, one group of rollers is horizontally arranged, and the other two groups of rollers are inclined. Damping spring assemblies are provided at both ends of the roller bracket, and the damping spring assembly consists of a roller screw rod frame, a compression spring, a spring stop sleeve and a movable stop sleeve. One end of the inclined roller is installed on the roller screw rod frame, and the other end is movably connected to the roller bracket. The spring stop sleeve is welded on the roller screw rod frame, and the stop sleeve is arranged on the roller screw rod frame. The upper end of the roller screw rod frame is lifted by the compression spring, and the lower end is fixed with double nuts and spring washers.

[0013] Furthermore, the transmission part includes an induction arc plate and an induction wheel. The induction arc plate is connected to the induction frame through an adjusting rod. The adjusting rod passes through the side wall of the induction frame and is slidably connected to the induction frame. An induction spring is provided on the adjusting rod. The induction spring presses the induction arc plate against the induction wheel. The induction wheel is connected to the power end of the one-way liquid pump. The rotation of the induction wheel drives the one-way liquid pump to work.

[0014] Furthermore, the adjustment rod is connected to the induction arc plate via a thread. When the induction arc plate is adjusted toward the induction frame, the contact length between the induction arc plate and the induction wheel can be shortened, so that under the same deflection condition, the induction wheel rotates a different number of times, thereby adjusting the oil pumping amount of the one-way liquid pump.

[0015] Furthermore, a worm and a driving wheel are provided on the housing of the one-way liquid pump, the worm is connected to the one-way wheel through a one-way bearing, the worm and the driving wheel are both movably connected to the one-way liquid pump, the one-way wheel is transmission-connected to the induction wheel through a friction wheel, the outer surfaces of the one-way wheel and the friction wheel are both made of rubber, the outer diameter of the friction wheel is larger than the outer diameter of the one-way wheel, and the driving wheel is transmission-connected to the power end of the one-way liquid pump.

[0016] The beneficial effects of the present invention are as follows:

[0017] The present application provides a corrector with a self-limiting and automatic oiling function. During correction, the correcting mechanism swings around the self-limiting stability shaft group. When the self-limiting stability shaft group swings, the one-way liquid pump is driven by the transmission part to work, so as to realize the adaptive and real-time pumping of lubricating oil into the self-limiting stability shaft group according to the working state of the self-limiting stability shaft group, which can not only reduce the loss of lubricating oil, but also ensure the timeliness of lubrication and reduce labor costs.

[0018] Thrust ball bearing-needle roller bearing-thrust ball bearing, combined with round nut lock washer and round nut fixation, greatly improves the stability of the self-limiting stability shaft group. The needle roller bearing is located between the two thrust bearings, reducing the axial pressure of the needle roller bearing and allowing the needle roller bearing to bear more radial pressure, thereby improving the life and stability of the self-limiting stability shaft group.

DETAILED DESCRIPTION

[0031] The following will clearly and completely describe the technical solutions in the embodiments of the present invention in conjunction with the accompanying drawings. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0032] For example 1, please refer to Figure 1A deviation corrector with self-limiting and automatic oiling function, hereinafter referred to as the deviation corrector, includes a supporting beam 1, an installation mechanism 2, a deviation correcting mechanism 3, a self-limiting stability shaft group 4 and an adaptive lubrication mechanism 5. The installation mechanism 2 is provided with two groups, and the two groups of installation mechanisms 2 are respectively arranged on both sides of the supporting beam 1. The self-limiting stability shaft group 4 is arranged in the middle of the supporting beam 1. The upper end of the self-limiting stability shaft group 4 is fixedly connected to the deviation correcting mechanism 3.

[0033] See also Figure 2 The mounting mechanism 2 includes an adjustable mounting frame 201 and a telescopic frame 202. The telescopic frame 202 is slidably connected to the supporting beam 1. In this embodiment, the telescopic frame 202 has two connecting columns 203, and the supporting beam 1 has two mounting sleeves corresponding to the connecting columns 203. The connecting columns 203 are movably connected to the mounting sleeves. The side walls of the mounting sleeves are provided with fastening screws for clamping the connecting columns 203. A row of holes is provided on the telescopic frame 202. The adjustable mounting frame 201 is fixedly connected to the telescopic frame 202 by bolts. The bolts pass through the row of holes. A height adjustment rod 205 is provided on the top of the adjustable mounting frame 201. The height adjustment rod 205 passes through the connecting block 204. By adjusting the relative position of the connecting block 204 and the height adjustment rod 205, the vertical position between the adjustable mounting frame 201 and the telescopic frame 202 can be adjusted. The adjustable mounting frame 201 is installed on the frame of the conveyor. By adjusting the vertical position between the adjustable mounting frame 201 and the telescopic frame 202, the height of the correcting mechanism 3 can be adjusted.

[0034] See also Figure 3 The self-limiting stability shaft group 4 includes a bearing sleeve 401, which is connected to a connecting shaft 409 through a bearing group 402. The connecting shaft 409 is fixedly connected to the correction mechanism 3. An oil drain hole 404 and an oil filling hole 413 are provided on the bearing sleeve 401. The lubricating oil flows in from the oil filling hole 413, soaks the bearing group 3, and is discharged from the oil drain hole 404.

[0035] See also Figure 2 、 Figure 4 and Figure 5The adaptive lubrication mechanism 5 includes an oil tank 501, a one-way liquid pump 502 and an induction frame 504. The oil tank 501 and the one-way liquid pump 502 are fixedly installed on one side of the supporting beam 1. A partition 507 is provided in the oil tank 501. The partition 507 divides the oil tank 501 into two parts: a new oil chamber and an old oil chamber. The partition 507 is fixedly connected to the bottom of the oil tank 501. A gap is left between the partition 507 and the top of the oil tank 501. When the lubricating oil is not replaced and added in time, the backflowing old oil can overflow the partition 507 and enter the new oil chamber to prevent insufficient lubrication due to failure to add and replace the lubricating oil in time. The induction frame 504 is fixedly connected to the correction mechanism 3. The induction frame 504 is transmission-connected to the one-way liquid pump 502 through the transmission member 503. The oil tank 501 is provided with an oil filling valve 508 and an oil drain valve 5 09, oil inlet pipe 511 and oil return pipe 512. Open the oil filling valve 508 to inject new lubricating oil into the oil tank 501, and open the oil drain valve 509 to drain the old lubricating oil. One end of the oil inlet pipe 511 passes through the bottom of the oil tank 501 and is connected to the oil tank 501. The other end of the oil inlet pipe 511 is connected to the input end of the one-way liquid pump 502. The output end of the one-way liquid pump 502 is connected to the oil filling hole 413 through the power pipe 506. One end of the oil return pipe 512 passes through the top of the oil tank 501, and the other end of the oil return pipe 512 is connected to the oil drain hole 404. The oil filling valve 508 and the oil inlet pipe 511 correspond to the new oil chamber, and the oil drain valve 509 and the oil return pipe 512 correspond to the old oil chamber. The side wall of the oil tank 501 is provided with a transparent observation window 510 for observing the oil level on both sides of the partition 507.

[0036] After the corrector is installed on the belt conveyor, when the belt deviates from the center line, it causes the correcting mechanism 3 to rotate around the self-limiting stability shaft group 4. When the correcting mechanism 3 rotates, it drives the sensing frame 504 to swing. The sensing frame 504 drives the one-way liquid pump 502 through the transmission part 503 to pump out the lubricating oil in the oil tank 501 and flow into the self-limiting stability shaft group 4 through the oil filling hole 413. The old lubricating oil in the self-limiting stability shaft group 4 flows out from the oil drain hole 404 and flows back to the oil tank 501.

[0037] In the prior art, the bearing group in the self-limiting stability shaft group 4 is generally composed of a thrust ball bearing and a deep groove ball bearing pair, which makes the bearing sleeve too large and easily deformed during welding. Therefore, a thick plate is required as the shaft group welding plate to control thermal deformation. The connection between this shaft group welding plate and the crossbeam has an additional process. In addition, the shaft group is very easy to shake during use. The upper end of the shaft can often fluctuate by 0.5-1.5mm. The shaking at the shaft group is transmitted to the end of the roller bracket 301, which can reach 4-5cm shaking. The sealing effect is poor, resulting in uneven force on the roller bracket 301 and poor correction effect.

[0038] To do this, see Figure 6 and Figure 7The bearing group 402 includes two groups of thrust ball bearings and one group of needle roller bearings. The needle roller bearing is located in the middle of the two groups of thrust ball bearings. Compared with the existing technology, the needle roller bearing is used as a radial fixed bearing, and its diameter is much smaller than that of the deep groove ball bearing, so that the overall diameter of the shaft group is reduced, and the diameter of the bearing sleeve 401 is reduced, thereby reducing the heat during the welding of the bearing sleeve 401. The shaft group welding plate can be discarded, and the bearing sleeve 401 can be directly welded to the supporting beam 1, reducing costs and processes. At the same time, the fluctuation of the upper end of the connecting shaft 409 is controlled at 0.1-0.3mm, and is transmitted to the end of the correction mechanism 3, which is only 2-3mm. The bearing group 402 is sleeved in the bearing sleeve 401, and the shaft cover is passed above the bearing group 402. 403 and the shaft are encapsulated with an elastic retaining ring 405, the lower end of the connecting shaft 409 is threaded and fixed by a stop washer 406 and a round nut 407, the lower end of the bearing sleeve 401 is connected to a dust cover 410, and keyways are milled on the dust cover 410 and the connecting shaft 409. The dust cover 410 and the connecting shaft 409 are connected together by a key, and a through hole is left at the bottom of the dust cover 410, which is connected to the stop washer 406 and the round nut 407 to prevent falling off. The anti-theft plate 408 is welded and then ground flat to prevent disassembly and imitation. The connection between the shaft cover 403 and the connecting shaft 409, the shaft cover 403 and the bearing sleeve 401, and the bearing sleeve 401 and the dust cover 410 is provided with a sealing ring ( Figure 6 and Figure 7 not shown).

[0039] A limit block 411 is provided on the bearing sleeve 401, and a limit groove 412 corresponding to the limit block 411 is provided on the dust cover 410. The limit block 411 and the limit groove 412 cooperate to limit the maximum rotation angle of the connecting shaft 409. Process grooves are provided on the connecting shaft 409 and the bearing sleeve 401. When the two are aligned, they are the positive angle, which can facilitate welding positioning. The limit structure is built into the correction mechanism 3, which has strong applicability and does not worry about problems such as interference with the on-site spatial structure and material clogging of the external limit mechanism. At the same time, due to the high machining precision, it is easier to ensure the limiting effect.

[0040] See also Figure 2The correction mechanism 3 includes a roller bracket 301, which is welded to the end of the connecting shaft 409. The roller bracket 301 is provided with rollers 302. There are three groups of rollers 302. One group of rollers 302 is horizontally arranged, and the other two groups of rollers 302 are inclined. When facing high belt speed conditions (conventional 3m / s belt speed, the speed of rollers 302 can reach 450r / min), due to the eccentricity of the roller shaft, the roller bracket 301 is prone to resonance and shaking. For this reason, damping spring assemblies 3 are provided at both ends of the roller bracket 301. 03. The damping spring assembly 303 consists of a roller screw frame 304, a compression spring 305, a spring stop sleeve 306, and a movable stop sleeve 307. One end of the tilted roller 302 is mounted on the roller screw frame 304, and the other end is movably connected to the roller bracket 301. The spring stop sleeve 306 is welded to the roller screw frame 304 to position the spring. The movable stop sleeve 307 is mounted on the roller screw frame 304. The spring stop sleeve 306 and the movable stop sleeve 307 are machined with a slope to prevent the spring from being scratched and damaged during expansion and contraction. The upper end of the roller screw frame 304 is supported by the compression spring 305, and the lower end is fixed with a double nut and a spring washer. The compression of the compression spring 305 can be adjusted by turning the nut. By adjusting the stroke of the compression spring 305, the performance of the damping spring assembly 303 can be changed.

[0041] See also Figure 8 and Figure 9 The transmission part 503 includes an induction arc plate 5032 and an induction wheel 5031. The induction arc plate 5032 is connected to the induction frame 504 through an adjusting rod 5034. The adjusting rod 5034 passes through the side wall of the induction frame 504 and is slidably connected to the induction frame 504. A protrusion is provided at the end of the adjusting rod 5034 to prevent it from falling out. The adjusting rod 5034 is connected to the induction arc plate 5032 through a thread. The induction wheel 5031 is connected to the power end of the one-way liquid pump 502. The induction wheel 5031 rotates to drive the one-way liquid pump 502 to work. The surface of the induction wheel 5031 is made of rubber. A support wheel 505 is provided at the bottom of the induction frame 504 to ensure the stability of the swing of the induction frame 504.

[0042] The induction spring 5033 is in a compressed state, and the induction arc plate 5032 is pressed against the induction wheel 5031. When correcting the deviation, the induction arc plate 5032 rotates with the correction mechanism 3. The induction arc plate 5032 drives the induction wheel 5031 to rotate through friction, thereby driving the one-way liquid pump 502 to work. The induction spring 5033 can be compressed to ensure that the induction arc plate 5032 drives the induction wheel 5031 within a certain range. At the same time, the induction spring 5033 and the induction arc plate 503 can be adjusted by twisting the adjustment rod 5034. 2, when the induction arc plate 5032 is adjusted toward the side of the induction frame 504, the contact length between the induction arc plate 5032 and the induction wheel 5031 can be shortened, so that under the same deflection condition, the number of rotations of the induction wheel 5031 is different, and the pumping amount of the one-way liquid pump 502 can be adjusted, thereby achieving the technical effect of lubricating the shaft group according to the actual working conditions, effectively solving the technical problem of lubricating oil waste in the prior art, and at the same time reducing the maintenance burden according to the working conditions, effectively improving the durability and life of the shaft group.

[0043] In this embodiment, the transmission member 503 uses friction to transmit data. In other embodiments, the transmission of the transmission member 503 can also be directly achieved by structures such as connecting rods and wedges, or can be indirectly achieved by transmission structures such as hydraulics and pneumatics. The one-way liquid pump 502 can be driven by the swing of the induction frame 504. For example, the swing of the end of the induction frame 504 can be converted into linear motion by using a connecting rod. If the one-way liquid pump 502 is a piston pump, it can directly drive the power end. Or if the one-way liquid pump 502 is a plunger pump, a vane pump, or other types that require rotation, a crank or gear, rack structure can be used to convert the straight line into rotational motion.

[0044] In the second embodiment, generally speaking, a plurality of deviation correctors are usually provided on the conveyor, and the deviation correctors at some positions have a small deviation correction amplitude. Correspondingly, the swing amplitude of the induction frame 504 is small, and the rotation angle of the induction wheel 5031 each time may be too small to drive the induction frame 504 to work, resulting in a lack of lubrication of the self-limiting stability shaft group 4, which reduces the service life. For this reason, based on the first embodiment, the second embodiment provides a worm 5035 and a driving wheel 5036 on the housing of the one-way liquid pump 502, and the worm 5035 is connected to the one-way wheel 5037 through a one-way bearing. The worm 5035 and the driving wheel 5036 are both movably connected to the one-way liquid pump 502, and the one-way wheel 5037 is driven by the induction wheel 5031 through the friction wheel. The outer surfaces of the one-way wheel 5037 and the friction wheel are made of rubber. When the induction wheel 503 When the one-way wheel 5037 rotates, the friction force drives the one-way wheel 5037, and the one-way wheel 5037 drives the worm 5035 to move. Under the action of the one-way bearing, the one-way wheel 5037 can only drive the worm 5035 in one direction. At the same time, the self-locking ability of the turbine and the worm is used to prevent the driving wheel 5036 and the worm 5035 from reversing. Every slight swing of the sensing frame 504 can be accumulated to ensure that the one-way liquid pump 502 can work and pump out lubricating oil. The outer diameter of the friction wheel is larger than the outer diameter of the one-way wheel 5037. The driving wheel 5036 rotates to drive the one-way liquid pump 502 to work. If the one-way liquid pump 502 works by rotation, the driving wheel 5036 directly drives the rotating shaft of the one-way liquid pump 502. If the one-way liquid pump 502 works by linear motion, the driving wheel 5036 drives the one-way liquid pump 502 to work through the crank 5038.

Various modifications to these embodiments will be readily apparent to one skilled in the art, and the general principles defined herein may be implemented in other embodiments without departing from the spirit or scope of the present invention.
