Description

Technical Field

[0001] The invention belongs to the technical field of scraper type slag scoop machines, and in particular relates to a scraper type slag scoop machine anti-chain derailment mechanism and a scraper type slag scoop machine. Background Art

[0002] Scraper type slag remover is a kind of equipment used for water treatment and sewage treatment. It is designed to efficiently remove floating objects on the water surface and sediments on the bottom of the water. It is widely used in sewage treatment plants, industrial wastewater purification and various water body maintenance. Its working principle is based on the reciprocating motion of the scraper along the water surface or bottom of the water to effectively collect and remove impurities. However, in actual operation, the scraper type slag remover faces some technical difficulties, especially the wear problem of the transmission chain, which not only shortens the life of the equipment, but also affects the operational stability. In addition, the expansion and contraction of the chain caused by temperature changes is also a major problem, which may cause the chain to loosen or tighten, thereby affecting work efficiency.

[0003] As a key component of the scraper dredger, the transmission chain is responsible for driving the scraper to move. Due to long-term operation in a humid and corrosive environment, coupled with continuous friction with the scraper, guide rails and other components, the transmission chain is very prone to wear. Wear not only reduces the strength and transmission efficiency of the chain, but may also cause the chain to loosen and then cause slippage. Slippage means that the equipment cannot run at the expected speed. In severe cases, it may even cause the equipment to stagnate, thus affecting the continuity and efficiency of the entire water treatment process.

[0004] In addition, temperature changes are also an important factor affecting the stable operation of the scraper type slag remover. As the ambient temperature rises or falls, the transmission chain and the connected metal parts will expand and contract. This physical change may cause the chain tension to change, increasing the risk of chain derailment. Once the chain is derailed, the equipment will stop working immediately, which will not only interrupt the water treatment process, but may also cause damage to the equipment itself, such as the scraper hitting the edge of the water tank, etc., which increases the difficulty of subsequent maintenance and repairs and reduces the durability of the scraper type slag remover. Summary of the invention

[0005] The object of the present invention is to overcome the above-mentioned problems and provide a scraper type slag bag anti-chain debonding mechanism and a scraper type slag bag, which can avoid the chain debonding of the transmission chain on the scraper type slag bag, effectively achieve the anti-chain debonding effect of the scraper type slag bag, and improve the durability of the scraper type slag bag.

[0006] In order to achieve the above object, the present invention adopts the following technical solution: In a first aspect, the present invention provides a chain-off prevention mechanism for a scraper type slag dredger, comprising a scraper slag dredger frame, a transmission gear being installed on one side of the interior of the scraper slag dredger frame, and a transmission chain being meshedly connected to the outer wall of the transmission gear; A U-shaped frame is installed at the bottom end of the scraper slag scoop frame, a first auxiliary gear is arranged above the U-shaped frame, a mounting frame is installed on the top of the U-shaped frame, guide grooves are symmetrically opened on both sides of the surface of the mounting frame, a movable work seat is installed inside the guide groove, and a second auxiliary gear is arranged below the movable work seat; The first auxiliary gear and the two second auxiliary gears on the same side are all meshed with the transmission gear to respectively lift and press the transmission gear.

[0009] A further improvement of the present invention is that a guide column is installed inside the mounting hole, and the outer wall of the guide column is slidably connected to the inner wall of the mounting hole.

[0010] A further improvement of the present invention is that a nut is threadedly connected to the upper portion of the outer wall of the guide column, and a pressure seat is installed at the bottom end of the guide column.

[0011] A further improvement of the present invention is that a second auxiliary gear is rotatably connected to the bottom of the pressure seat, and the second auxiliary gear is meshedly connected to the transmission chain.

[0012] A further improvement of the present invention is that a spring is arranged below the outer wall of the guide column.

[0013] A further improvement of the present invention is that a fixed block is fixedly arranged on the outer side of the movable work-type seat, and the fixed block is penetrated by a first through hole along the length direction.

[0014] A further improvement of the present invention is that a second through hole is formed through the mounting frame along the length direction, the first through hole is communicated with the second through hole, and the first through hole and the second through hole are fixedly connected by bolts.

[0015] In a second aspect, the present invention further provides a scraper type slag dredger, comprising the above-mentioned anti-chain-off mechanism of the scraper type slag dredger.

[0016] Compared with the prior art, the present invention has the following beneficial effects: The present invention provides an anti-chain debonding mechanism for a scraper type slag scoop machine, by installing a U-shaped frame at the inner bottom end of a scraper type slag scoop machine frame, arranging a first auxiliary gear above the U-shaped frame, and installing a mounting frame at the top of the U-shaped frame, guide grooves are symmetrically provided on both sides of the surface of the mounting frame, a movable work seat is installed inside the guide groove, and a second auxiliary gear is arranged below the movable work seat, and the first auxiliary gear and the second auxiliary gear are tightly meshed with the transmission gear inside the scraper type slag scoop machine frame, the first auxiliary gear presses the transmission chain, and the second auxiliary gear presses the transmission chain to form an S-shaped state, which effectively prevents the transmission chain from loosening and falling off. This design significantly improves the operating stability of the scraper type slag scoop machine, reduces the downtime and maintenance cost caused by chain debonding, and improves the durability of the scraper type slag scoop machine.

[0017] Furthermore, a hydraulic cylinder is installed inside the U-shaped frame, and a moving seat is installed at the output end of the hydraulic cylinder.

[0033] A spring 405 is provided below the outer wall of the guide column 402. The spring 405 is mounted on the outer wall of the guide column 402. According to the effect of the elastic reaction force of the spring 405, the transmission chain 102 is lifted upward by the first auxiliary gear 203, and the second auxiliary gear 406 and the spring 405 press the transmission chain 102 downward to form an S-shaped state. The transmission chain 102 in the compressed state has a certain tensioning effect, thereby preventing the transmission chain 102 from being derailed.

This design improves the stability and reliability of the mechanism and prevents the mobile work-type seat 4 from shaking or falling off during operation.

[0035] How it works When using the present invention, the U-shaped frame 2 is arranged below the transmission chain 102 on the scraper slag scooping machine frame 1, and the first auxiliary gear 203 is fixedly installed by the mobile seat 202 at the output end of the hydraulic cylinder 201 on the U-shaped frame 2. According to the loose state of the transmission chain 102, the first auxiliary gear 203 is driven by the hydraulic cylinder 201 to press and mesh with the transmission chain 102, so that the scraper slag scooping machine can be tensioned. By docking the four groups of mobile work-shaped seats 4 in the guide groove 301 on the mounting frame 3 in a sliding manner, and docking its fixing block 302 in the guide groove 301, according to the first through hole 303 on the fixing block 302 and the second through hole 304 corresponding to the mounting frame 3, the first through hole 303 and the second through hole 304 are tightened by the fastening bolts, so that the mobile work-shaped seat 4 can be installed and fixed, and by docking the pressure seat 404 in the mounting hole 4 on the mobile work-shaped seat 4 in a sliding manner by the guide column 402 01, and tighten the nut 403 on the outer wall of the guide column 402 in a threaded connection manner, so that the guide column 402 can move vertically up and down on the mobile work-type seat 4. At the same time, the installed nut 403 can limit the guide column 402 to prevent the guide column 402 from detaching from the mobile work-type seat 4. By installing a spring 405 on the outer wall of the guide column 402, according to the effect of the elastic reaction force of the spring 405, the transmission chain 102 that is lifted upward by the first auxiliary gear 203 is pressed downward by the second auxiliary gear 406 and the spring 405 to form an S-shaped state. The transmission chain 102 in the pressed state has a certain tensioning effect. The transmission chain 102 in the tensioned state can avoid the transmission chain 102 on the scraper type slag collector from being decoupled, thereby reducing the downtime and maintenance costs caused by decoupling, and improving the durability of the scraper type slag collector.

[0036] The embodiment of the present invention also provides a scraper type slag picker with the above-mentioned anti-chain derailment mechanism. The scraper type slag picker adopts the above-mentioned anti-chain derailment mechanism, and tightens the transmission chain 102 through the first auxiliary gear 203 to ensure that the transmission chain 102 maintains appropriate tension during high-speed operation. The second auxiliary gear 406 presses the transmission chain 102, which complements the tightening effect of the first auxiliary gear 203, and together causes the transmission chain 102 to present a stable S-shaped state, effectively preventing the transmission chain 102 from loosening and falling off, so that the scraper type slag picker can significantly reduce the number of unexpected shutdowns caused by the derailment of the transmission chain 102 during operation, greatly reducing the maintenance frequency and cost, and extending the overall service life of the equipment.
