Description

Technical Field

[0001] The present invention relates to the technical field of scraper conveyors, and more specifically, to a scraper conveyor round link chain with a tension detection mechanism. Background Art

[0002] In coal mine work, scraper conveyors are needed to transport coal and materials. The working principle of scraper conveyors is to use an open chute as a bearing for coal, gangue or materials, and fix the scraper on the chain to form a scraper chain as a traction component. When the head transmission part is started, the sprocket on the head shaft is driven to rotate, so that the scraper chain circulates and drives the material to move along the chute until it is unloaded at the head. The scraper chain bypasses the sprocket for a stepless closed cycle to complete the material transportation. During the operation of the scraper conveyor, it is necessary to check the tightness of the scraper chain, because the connection between the chutes will reduce the spacing due to operation. If the chain is too loose, there will be accidents such as chain jamming, chain jumping, chain breaking or chain falling off the track. The way to check whether the chain needs to be tightened is to reverse the scraper conveyor and count the number of loose chain links. If there are more than two completely loose chain links, the chain needs to be tightened again.

[0003] Among them, the patent with announcement number CN210437928U discloses a chain tightening device for a scraper conveyor, which includes an air pipe, a pneumatic plunger pump, a pneumatic cylinder, a high-strength bolt, and a round-ring chain, wherein the pneumatic plunger pump is connected to the pneumatic cylinder, and both ends of the pneumatic cylinder are connected to a piston rod, and the top of each piston rod is connected to two round-ring chains through a high-strength bolt, and the top of each round-ring chain is connected to the large chain of the scraper conveyor on the same side;

[0004] When this structure is in use, air is transported to the pneumatic plunger pump through the air pipe, and then the pneumatic plunger pump is pressurized, the piston rod of the pneumatic cylinder moves, pulling the round link chain, tightening the large chain of the scraper conveyor, and completing the chain tightening action. However, this structure can only adjust the tension of a single chain when in use, which makes it cumbersome to adjust different chains, and it is not easy to adjust the angle appropriately according to needs, resulting in greater wear when the chain or sprocket is offset. Summary of the invention

[0005] In order to overcome the above-mentioned defects of the prior art, the present invention provides a scraper conveyor round link chain with a tension detection mechanism, aiming to solve the problems raised in the above-mentioned background technology.

[0006] The present invention provides the following technical solution: a scraper conveyor round link chain with a tension detection mechanism, comprising a base, on which a support adjustment assembly is provided;

[0007] The support adjustment assembly includes two reinforcing uprights arranged on the top of the base, a reinforcing support shaft between the two reinforcing uprights, both ends of the reinforcing support shaft are fixedly provided with limit plates, one side of the two limit plates is provided with a rotating disk, the rotating disk is sleeved on the reinforcing support shaft and rotatably connected to the reinforcing support shaft, a supporting ring is fixedly arranged on the outer side of the rotating disk, and a first sprocket is installed on one side of the supporting ring through bolts;

[0008] The bottoms of the two reinforcing vertical poles are hinged with reinforcing cross bars, and each of the reinforcing cross bars is hinged with an angle-adjustable electric push rod, a traction rod is provided at the output end of the electric push rod, and an angle-adjustable shaft pin plate is hinged at one end of the traction rod, a slide groove is provided on one side of the reinforcing vertical pole, and the shaft pin plate extends into the slide groove and is slidably connected to the slide groove;

[0009] It can be seen that in the above technical solution, the chain is laid on the first sprocket and the second sprocket, and the chain is supported by the first sprocket and the second sprocket. When the chain needs to be tensioned and adjusted, the electric push rod is started, and the output end of the electric push rod drives the traction rod and the shaft pin plate to move. The shaft pin plate and the slide groove rub against each other, and then the traction force of the reinforcing vertical rod when the shaft pin plate and the traction rod are displaced is adjusted at an angle on the reinforcing cross bar, thereby realizing the function of adjusting the tension. At the same time, the tension of the chain is detected by the stroke extended by the output end of the electric push rod, ensuring the convenience of its detection and adjustment.

[0010] A plurality of reinforcing frames are fixedly arranged on the outer sides of the two limit plates, and a limited protection ring is fixedly arranged on one end of each of the reinforcing frames, a reinforcing support ring body is arranged between the two limited protection rings, a calibration groove is opened on the outer side of the reinforcing support ring body, and a second sprocket is arranged in the calibration groove, the second sprocket is mounted on the reinforcing support ring body by bolts, a plurality of reinforcing arc support strips are arranged on the inner wall of the reinforcing support ring body, and the two ends of each of the reinforcing arc support strips are respectively fixed on the corresponding limited protection ring, both ends of the reinforcing support shaft are rotatably connected with bearing seats, the bearing seats are mounted on the side faces of the reinforcing vertical poles by bolts, a reinforcing support frame is arranged at the bottom of the reinforcing cross bar, the reinforcing support frame is fixed on the base, and the reinforcing support frame is a rectangular frame structure, a reinforcing rotating rod is fixedly arranged in the middle of the reinforcing support frame, the reinforcing rotating rod is inserted in the middle of the reinforcing cross bar and is rotatably connected to the reinforcing cross bar;

[0011] It can be seen that in the above technical solution, when the chain is laid on the second sprocket, the two sides thereof are blocked by the reinforced support ring body, so as to realize the function of calibration and positioning when laying the chain, thereby ensuring the stability of the chain during transmission, and the first sprocket is rotatably connected to the reinforced support shaft through the support ring and the turntable, while the second sprocket is fixed to the reinforced support shaft through the reinforced support ring body and the limit plate, so that the second sprocket and the first sprocket can rotate independently, and it is easy for chains in different directions to be laid on the device;

[0012] A limited position seat is arranged on one side of the surface of the reinforcing cross bar, and the limited position seat is installed on the base through bolts, a slide is slidably connected to the middle part of the limited position seat, a connecting buckle is arranged at one end of the slide, a limited position hook is arranged on the connecting buckle, and the limited position hook is hooked on the reinforcing cross bar, a wire groove is arranged on both sides of the slide, a knob is sleeved on one end of the limited position seat, and the knob is rotatably connected to the limited position seat, a reinforcing wire tube is fixedly arranged in the middle part of the knob, the reinforcing wire tube is threadedly connected to the wire groove, and one end of the limited position seat is hinged to the limited position buckle;

[0013] It can be seen that in the above technical solution, by rotating the knob, the reinforcing wire drum is driven to rotate when the knob is rotated, and the wire groove is threadedly connected to the reinforcing wire drum, so that the slide plate is displaced on the limit seat through the wire groove by the torque when the reinforcing wire drum rotates, thereby realizing the function of adjusting the position of the slide plate, and when the slide plate is displaced, it will pull the connecting buckle and the limit hook, thereby enabling the reinforcing cross bar to drive the reinforcing vertical rod to adjust the angle on the reinforcing support frame through the reinforcing rotating rod, so that the device can easily adjust the angle adapted to the chain according to the needs, avoid wear of the chain and the device, and ensure the stability of the chain during transportation;

[0014] Technical effects and advantages of the present invention:

[0015] 1. The present invention supports the chain by the first sprocket and the second sprocket, and the shaft pin plate and the slide groove rub against each other, so that the traction force of the reinforcing vertical rod when it passes through the shaft pin plate and the traction rod is adjusted at an angle on the reinforcing cross bar, thereby realizing the function of adjusting the tension. At the same time, the tension of the chain is detected by the stroke extended by the output end of the electric push rod, ensuring the convenience of its detection and adjustment;

[0016] 2. When the chain of the present invention is laid on the second sprocket, the two sides thereof are blocked by the reinforced support ring body, so as to realize the function of calibration and positioning when laying, and ensure the stability of the chain during transmission. The first sprocket is rotatably connected with the reinforced support shaft through the support ring and the turntable, while the second sprocket is fixed with the reinforced support shaft through the reinforced support ring body and the limit plate, so that the second sprocket and the first sprocket can rotate independently, and it is easy for chains in different directions to be laid on the device;

[0017] 3. In the present invention, the slide plate is displaced on the limit seat through the wire groove by the torque of the reinforcing wire drum during rotation, thereby realizing the function of adjusting the position of the slide plate. When the slide plate is displaced, the connecting buckle and the limit hook are pulled, so that the reinforced cross bar can drive the reinforced vertical bar to adjust the angle on the reinforced support frame through the reinforced rotating rod. It is easy for the device to adjust the angle to match the chain according to the needs, avoiding wear between the chain and the device, and ensuring the stability of the chain during transportation.

[0018] To sum up, through the corresponding coordinated use of various structures, the traction force of the reinforced vertical pole when it passes through the axle pin plate and the traction rod is displaced is adjusted at an angle on the reinforced cross bar, thereby realizing the function of adjusting the tension. At the same time, the stroke extended by the output end of the electric push rod is used to detect the tension of the chain, thereby ensuring the convenience of detection and adjustment. The second sprocket and the first sprocket can rotate separately, which makes it easy for chains in different directions to be laid on the device, thereby improving the diversity of the device when used. At the same time, the reinforced cross bar drives the reinforced vertical pole to be adjusted at an angle on the reinforced support frame through the reinforced rotating rod, which makes it easy for the device to adjust the angle to match the chain according to needs, thereby avoiding wear of the chain and the device, and ensuring the stability of the chain during transportation.
