Abstract
Description
Technical Field
[0001] This utility model relates to the field of cleaning equipment technology, specifically to a chain extension alarm device for a high-strength rotary cleaning machine. Background Technology
[0002] The cleaning machine mainly uses a drive mechanism to drive two sets of chains to operate stably inside an irregular track. Several sets of rake teeth are fixedly installed between the two sets of chains. The rotation of the chains drives the rake teeth to retrieve debris in the water, such as branches, dead leaves, debris, and floating garbage.
[0003] When a cleaning machine operates under heavy load for extended periods, the chain gap gradually increases, leading to excessive chain length and loosening. Once the chain loosens to a certain length, the working rollers on the cleaning machine will press against the outer guide rail, and the rake teeth, under gravity, will cause the chain to drop, potentially contacting the cleaning teeth. This prevents the cleaning machine from operating normally. If not addressed promptly, this not only reduces the efficiency of cleaning debris but also damages the equipment. Existing equipment lacks a chain extension alarm device, making it impossible to detect chain loosening in a timely manner. Therefore, we need to propose a high-strength rotary cleaning machine chain extension alarm device. Utility Model Content
[0004] The purpose of this invention is to provide a chain extension alarm device for a high-strength rotary cleaning machine. Two sets of sliding components support the arc-shaped plates in two sets of irregularly shaped guide rails. High-strength bolts mounted on a fixed base support the movable seat, which in turn supports a sliding rod. The sliding rod supports the arc-shaped plates via an auxiliary roller mounted on the top. During normal operation, the downward pressure of the chain on the arc-shaped plates is relatively small. As the equipment operates normally, and the chain wears and loosens, gradually lengthening, the downward pressure on the arc-shaped plates gradually increases, causing the arc-shaped plates to rotate downwards. This downward rotation of the arc-shaped plates compresses the auxiliary roller, indirectly pushing the sliding rod downwards. The sliding rod then moves the movable seat downwards. When the chain loosens to a certain value, indirectly causing the movable seat to move to its maximum value, the alarm component's contacts are triggered, activating the alarm and alerting personnel to address the chain extension issue. This prevents equipment damage due to the failure to promptly detect chain extension and loosening, thus solving the problems mentioned in the background art.
[0005] To achieve the above objectives, this utility model provides the following technical solution: a high-strength rotary cleaning machine chain extension alarm device, comprising two sets of irregularly shaped guide rails, with an arc-shaped plate rotatably installed at the bottom of the entrance of each of the two sets of irregularly shaped guide rails, and a set of sliding components for support provided at the bottom of each of the two sets of arc-shaped plates, with an alarm component installed inside each of the two sets of sliding components, each of the two sets of sliding components including two sets of protective boxes, with a set of fixed seats fixedly installed at the bottom of the inner cavity of each of the two sets of protective boxes, a set of high-strength springs fixedly installed at the top of each of the two sets of fixed seats, a set of movable seats fixedly installed at the top of each of the two sets of movable seats, and a set of sliding rods fixedly installed at the top of each of the two sets of sliding rods extending to the top of one set of protective boxes, and an auxiliary wheel installed at the top of each of the two sets of sliding rods via a rotating seat, with the tops of the two sets of auxiliary wheels respectively abutting against the bottom of one set of arc-shaped plates.
[0006] Preferably, the alarm component includes a limit switch bolted to the inner wall of the protective box, and a movable operating head is provided on one side of the limit switch.
[0007] Preferably, a push rod is fixedly installed on one side of the movable seat, and one end of the push rod is fixedly connected to one end of the operating head.
[0008] Preferably, one end of the limit switch is connected to an audible and visual alarm via a circuit, and the audible and visual alarm is installed on the top of the protective box.
[0009] Preferably, a sliding sleeve is installed through the top of the protective box, and the middle part of the sliding rod is slidably installed inside the sliding sleeve.
[0010] Preferably, a set of support frames is fixedly installed on the outer side of each of the two sets of irregular guide rails, the top of the support frame is fixedly bolted to a set of support plates, and the bottom of each of the two sets of protective boxes is installed on the top of a set of support plates.
[0011] Compared with the prior art, the beneficial effects of this utility model are: This invention utilizes two independently configured sliding components and an alarm component. As the chains wear and loosen, gradually lengthening, the downward pressure exerted by the chains on the arc-shaped plate gradually increases, causing the arc-shaped plate to rotate downwards. This downward rotation of the arc-shaped plate compresses the auxiliary rollers, indirectly pushing the sliding rod downwards. The sliding rod then moves the movable seat downwards. When the chain loosens to a certain value, indirectly causing the movable seat to move to its maximum value, the alarm component's contacts are triggered, activating the alarm and alerting staff to the need for chain extension maintenance. This prevents equipment damage caused by the failure to promptly detect chain loosening.

The objectives and other advantages of this invention can be realized and obtained through the structures pointed out in the description and the accompanying drawings. Attached Figure Description

[0015] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.
[0016] Please see Figures 1-5This utility model provides a high-strength rotary cleaning machine chain extension alarm device, including two sets of irregular guide rails 1. An arc-shaped plate 2 is rotatably installed at the bottom of the entrance of each of the two sets of irregular guide rails 1. A set of sliding components 3 for support is provided at the bottom of each of the two sets of arc-shaped plates 2. An alarm component 4 is installed inside each of the two sets of sliding components 3. Each of the two sets of sliding components 3 includes two sets of protective boxes 33. A set of fixed seats 34 is fixedly installed at the bottom of the inner cavity of each of the two sets of protective boxes 33. A set of high-strength springs 35 is fixedly installed at the top of each of the two sets of high-strength springs 35. A set of movable seats 36 is fixedly installed at the top of each of the two sets of movable seats 36. A set of sliding rods 37 is fixedly installed at the top of each of the two sets of sliding rods 37, extending above each of the protective boxes 33. An auxiliary wheel 39 is installed at the top of each of the two sets of sliding rods 37 via a rotating seat. The tops of the two sets of auxiliary wheels 39 are respectively attached to the bottom of each of the arc-shaped plates 2.
[0017] In use, the two sets of sliding components 3 support the arc plates 2 in the two sets of irregular guide rails 1 respectively. The high-strength bolts installed on the fixed seat 34 support the movable seat 36, which in turn supports the sliding rod 37. The sliding rod 37 supports the arc plate 2 through the auxiliary rollers mounted on the top. During normal operation, the downward pressure of the chain on the arc plate 2 is small. As the equipment works normally, the chain wears and loosens, gradually increasing its length. The downward pressure of the chain on the arc plate 2 gradually increases, causing the arc plate 2 to rotate downwards. When the arc plate 2 rotates downwards, it presses against the auxiliary rollers, indirectly pushing the sliding rod 37 downwards. The sliding rod 37 then drives the movable seat 36 downwards. When the chain loosens to a certain value, it indirectly drives the movable seat 36 to its maximum value. After the movable seat 36 moves to a certain value, it triggers... The alarm component 4 contacts activate the alarm, reminding staff to repair the chain extension problem and avoid equipment damage caused by failure to detect chain extension loosening in time. The fixed seat 34 and the movable seat 36 are mainly used for the stable installation of the high-strength spring 35 and subsequent stable compression and extension, preventing the spring from tilting and shaking. With the auxiliary wheel 39 and the arc plate 2 set, the auxiliary wheel 39 can rotate in contact when the arc plate 2 is pressed down, reducing the wear of the arc plate 2 without affecting the downward movement of the slide bar 37, and improving the stability of the support device. The protective box 33 provides support and protection for the sliding component 3 and the alarm component 4. The arc plate 2 and the bottom of the entrance of the special-shaped guide rail 1 are rotatably connected by a welded pin seat. The connection is kept smooth and without sharp edges to prevent the chain from jamming.
[0018] The alarm component 4 includes a limit switch 41 bolted to the inner wall of the protective box 33. A movable operating head 42 is provided on one side of the limit switch 41, and a push rod 40 is fixedly installed on one side of the movable base 36. One end of the push rod 40 is fixedly connected to one end of the operating head 42. One end of the limit switch 41 is connected to an audible and visual alarm 43 through a circuit. The audible and visual alarm 43 is installed on the top of the protective box 33. The chain extension indirectly causes the movable base 36 to move downward. As the movable base 36 moves downward, the L-shaped push rod 40 pushes the operating head 42 of the limit switch 41 to move downward. When the operating head 42 moves to the contact of the limit switch 41, the circuit inside the limit switch 41 is closed, and the audible and visual alarm 43 connected to the limit switch 41 starts to emit an audible and visual alarm. The audible and visual alarm 43 is located on the top of the protective box 33, and the installation position is relatively conspicuous, making it convenient for staff to discover or hear the alarm at the first time.
[0019] A sliding sleeve 38 is installed through the top of the protective box 33, and a sliding rod 37 is slidably installed through the middle of the sliding sleeve 38. Through the setting of the sliding sleeve 38, the sliding rod 37 slides up and down inside the sliding sleeve 38, which prevents the sliding rod 37 from tilting and improves the stability of the movement of the sliding rod 37.
[0020] A set of support frames 31 is fixedly installed on the outer side of each of the two sets of irregular guide rails 1. The top of the support frame 31 is fixedly bolted to a set of support plates 32. The bottom of the two sets of protective boxes 33 are respectively installed on the top of a set of support plates 32. The support frame 31 is the support structure for the cleaning machine installation. It is not fully drawn in the figure. Through the connection relationship between the protective box 33, the support plate 32, and the support frame 31, the protective box 33 is bolted to the top of the support frame 31 through the support plate 32. The protective box 33 is located at the bottom of the arc plate 2, so as to achieve the effect of stable installation of the protective box 33.
[0021] The high-strength spring 35 is made of corrosion-resistant stainless steel. The sliding sleeve 38 has a sealing box inside to prevent water from flowing into the protective box 33 along the sliding rod 37 and causing internal corrosion. At the same time, a maintenance door is installed on one side of the protective box 33 to facilitate maintenance of the internal limit switch 41, high-strength spring 35 and other structures. Considering the difference in the degree of wear between the two sets of chains, the sliding component 3 and the alarm component 4 in this application are each provided in two sets, which are used to independently support and monitor the two symmetrically arranged chains. This can accurately determine which chain extends beyond the standard value range and improve maintenance efficiency.
[0022] In practical use: Under normal conditions, the chain runs normally along the irregular guide rail 1, maintaining stable pressure on the arc plate 2. The arc plate 2 remains stable, and the auxiliary wheel 39, supported by the high-strength spring 35, is in contact with the bottom of the arc plate 2. The moving seat 36 is in its initial position, the push rod 40 does not push the operating head 42, the limit switch 41 is not triggered, and the audible and visual alarm 43 is in the off state. When the chain gradually extends, if the chain extension exceeds the safety threshold, the chain's running trajectory shifts downward, increasing the pressure on the arc plate 2 and pushing the arc plate 2 to rotate downward around the pin axis. The bottom of the arc plate 2 presses against the auxiliary wheel 39, causing the auxiliary wheel 39 to move downward, which in turn drives the slide rod 37 to slide downward along the sliding sleeve 38. The moving seat 36 is pushed to compress the high-strength spring 35. Simultaneously, the moving seat 36 drives the push rod 40 to move downward. The push rod 40 pushes the operating head 42 of the limit switch 41 to the trigger stroke. The internal contacts of the limit switch 41 are activated, and an electrical signal is output to the audible and visual alarm 43. The audible and visual alarm 43 is activated and emits an audible and visual alarm. After hearing the alarm, the operator can stop the machine in time to check the chain status, replace or adjust the chain. After the chain returns to normal, the pressure on the arc plate 2 disappears, the high-strength spring 35 resets, and pushes the moving seat 36, slide rod 37, and auxiliary wheel 39 to move upward. The push rod 40 and the operating head 42 reset, the limit switch 41 is deactivated, the audible and visual alarm 43 is turned off, and the equipment can be restarted.
[0023] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
