Description

Technical Field

[0001] This utility model relates to the technical field of gantry-type sludge scrapers, specifically a gantry-type sludge scraper correction device. Background Technology

[0002] The gantry-type sludge scraper is a key piece of equipment in water treatment projects used to remove sludge from the bottom of sedimentation tanks. It uses an end beam frame to drive a working bridge and scraper blades in a reciprocating motion above the sedimentation tank, achieving sludge collection and removal. In actual operation, due to track installation errors, drive wheel slippage, or uneven load, the sludge scraper is prone to deviation. Deviation not only causes the scraper blades to collide with the tank walls or bottom scrapers, resulting in equipment damage, but also affects the scraping effect. Therefore, it is necessary to correct the deviation of the gantry-type sludge scraper.

[0003] In the prior art, such as the gantry-type sludge scraper self-control correction device proposed in patent application number "CN202122621285.9", both outer edges of the end beam frame are equipped with detection devices. The detection devices are electrically connected to the drive components. The drive components increase or decrease the rotation speed of the drive components according to the control signal issued by the detection devices, that is, adjust the speed of the traveling wheels.

[0004] However, the correction device in the aforementioned patent application uses sensors to detect the deviation and adjusts the speed of the drive motor in real time through a complex electrical control system to achieve correction. This has the problems of high reliability requirements for sensors and control components, relatively high equipment cost and failure rate, and the fact that the correction components are located below the end beam frame, making maintenance inconvenient. Utility Model Content

[0005] The purpose of this invention is to provide a deviation correction device for a gantry-type sludge scraper to solve the problems mentioned in the background art.

[0006] The objective of this utility model can be achieved through the following technical solutions:

[0007] A gantry-type sludge scraper correction device includes an end beam frame erected above a sedimentation tank, and fixed lateral adjustment plates on both sides of the top of the sedimentation tank; multiple correction adjustment wheels are provided on the top of the end beam frame, and the wheel surfaces of the correction adjustment wheels contact the inner sidewalls of the lateral adjustment plates.

[0008] The outer ring of the correction adjustment wheel is provided with an annular groove, and a replaceable rubber sleeve is fitted inside the annular groove. The rubber sleeve can be fitted or removed by its own elastic expansion.

[0009] The end beam frame is equipped with a lateral displacement mechanism, which is connected to the correction adjustment wheel and is used to adjust the lateral position of the correction adjustment wheel.

[0010] Preferably, a working bridge is fixedly connected to the bottom of the end beam frame and is driven by a drive unit to move along the guide rail laid on the top of the sedimentation tank.

[0011] Preferably, there are four correction and adjustment wheels, which are respectively set at the four corners of the top of the end beam frame.

[0014] The fixing plate has a first fixing groove and a second fixing groove along its length.

[0015] Preferably, the sliding sleeve is provided with a fixing mechanism, which includes a clamping block. Under the action of the tension spring, the clamping block can be selectively engaged in the first fixing groove or the second fixing groove to lock the correction adjustment wheel in the working position or the maintenance position.

[0016] The fixing mechanism also includes a fixing sleeve fixed to one side of the sliding sleeve, a tension spring located inside the fixing sleeve, and one end of the clamping block extending out and engaging into the fixing groove under the thrust of the tension spring.

Detailed Implementation

[0027] 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 skilled in the art without creative effort are within the protection scope of the present utility model.

[0028] like Figure 1 , Figure 2 and Figure 4 A gantry-type sludge scraper correction device includes an end beam frame 2 located above a sedimentation tank 1. The end beam frame 2 can move horizontally above the sedimentation tank 1. A working bridge 3 is fixedly connected to the bottom of the end beam frame 2. A scraper plate (not shown in the figure, with the bottom of the scraper plate in contact with the bottom of the sedimentation tank 1) can be installed on the working bridge 3. The end beam frame 2 drives the working bridge 3 to move, and the working bridge 3 drives the scraper plate to move within the sedimentation tank 1, which can clean the sludge at the bottom of the sedimentation tank 1.

[0029] like Figure 1The bottom of the end beam frame 2 is equipped with a drive component 13, which is a servo motor with an external power supply. It is automatically controlled by a PLC circuit. The servo motor and the PLC circuit that controls the servo motor are existing technologies and will not be described in detail here. The output end of the drive component 13 is fixedly connected to a drive wheel 14. The top of the sedimentation tank 1 is fixedly equipped with a guide rail 15 that works with the drive wheel 14. The drive component 13 drives the drive wheel 14 to move on the guide rail 15, thereby realizing the horizontal movement of the end beam frame 2.

[0030] like Figure 1 , Figure 2 and Figure 4 Rotatable correction adjustment wheels 4 are provided at the four corners of the top of the end beam frame 2. The outer ring of the correction adjustment wheel 4 is provided with an annular groove, and a rubber sleeve 401 is fitted inside the annular groove. The rubber sleeve 401 can be fitted onto the correction adjustment wheel 4 or removed from the correction adjustment wheel 4 by means of the elastic expansion of the rubber sleeve 401. The rubber sleeve 401 can be tightened onto the correction adjustment wheel 4 by means of the elastic contraction of the rubber sleeve 401.

[0031] The top of the sedimentation tank 1 has two outward protrusions on both sides to form extended support platforms 101. Lateral adjustment plates 5 are fixedly connected to both extended support platforms 101. On the side of the two lateral adjustment plates 5 that are close to each other, a wear-resistant metal layer 501 made of manganese steel is fixed in an embedded manner. The wear-resistant metal layer 501 and the correction adjustment wheel 4 are at the same height, so that the surface of the rubber sleeve 401 and the wear-resistant metal layer 501 are in contact. There is a gap between the two sides of the end beam frame 2 and the lateral adjustment plates 5, so that it does not contact the lateral adjustment plates 5.

[0032] Two sets of symmetrical lateral displacement mechanisms are provided on the end beam frame 2. Each lateral displacement mechanism is used to drive two correction adjustment wheels 4 located on the same side to move. The lateral displacement mechanism includes a first end fixing block 601 and a second end fixing block 602. The first end fixing block 601 and the second end fixing block 602 are both fixed to the top of the end beam frame 2. A fixing plate 603 is fixedly connected between the first end fixing block 601 and the second end fixing block 602. A sliding sleeve 604 is slidably connected to the fixing plate 603. Bending connecting plates 605 are fixedly connected to both sides of the sliding sleeve 604. A vertical shaft is fixed to the top of the other end of the bending connecting plate 605. The top of the vertical shaft is rotatably connected to the center of the correction adjustment wheel 4 through a bearing.

[0033] like Figure 3 and Figure 4 The fixing plate 603 has a first fixing groove 7 and a second fixing groove 8, and the first fixing groove 7 and the second fixing groove 8 are the same size;

[0034] A fixing mechanism is provided on one side of the sliding sleeve 604. The fixing mechanism includes a fixing sleeve 901 fixed to one side of the sliding sleeve 604. A tension spring 902 is fixedly connected inside the fixing sleeve 901. A clamping block 903 is fixedly connected to one end of the tension spring 902 and has a pushing force on the clamping block 903 in the direction of the first fixing groove 7. One end of the clamping block 903 extends into the first fixing groove 7 and is adapted to the first fixing groove 7, which can restrict the movement of the fixing sleeve 901 and the sliding sleeve 604.

[0035] The fixed sleeve 901 is fixedly connected to the movable slot 10, and the top of the clamping block 903 is fixedly connected to the movable block 11. The movable block 11 and the movable slot 10 are slidably connected. The top of the movable block 11 is fixedly connected to the control lever 12. The top of the control lever 12 is provided with anti-slip texture to facilitate manual operation of the control lever 12.

[0036] The working principle of the gantry-type sludge scraper correction device provided by this utility model is as follows:

[0037] When the end beam frame 2 moves above the sedimentation tank 1, the correction adjustment wheel 4 and the lateral adjustment plate 5 collide, causing the correction adjustment wheel 4 to rotate, which does not affect the movement of the end beam frame 2. When the end beam frame 2 shows a tendency to deviate, the lateral adjustment plate 5 will block the deviation of the correction adjustment wheel 4, preventing the end beam frame 2 from deviating, so that the sludge scraper will not deviate when scraping sludge.

[0038] When the rubber sleeve 401 on the correction adjustment wheel 4 in the correction device wears out after long-term use, it can be operated directly above the end beam frame 2. Pull the control lever 12 to one side. The control lever 12 drives the clamping block 903 to move through the movable block 11. The clamping block 903 separates from the first fixing groove 7. Then, pull the sliding sleeve 604 away from the lateral adjustment plate 5. The sliding sleeve 604 drives the correction adjustment wheel 4 to separate through the bending connecting plate 605, and makes the clamping block 903 snap into the second fixing groove 8. At this time, the rubber sleeve 401 can be removed and replaced with a new rubber sleeve 401 (the replacement method and tools of the rubber sleeve 401 using its elasticity are existing technologies and will not be described here).

[0039] After replacing the new rubber sleeve 401, pull the control lever 12 to separate the clamping block 903 and the second fixing groove 8. Then move the sliding sleeve 604 towards the lateral adjustment plate 5 and use the clamping block 903 to engage with the first fixing groove 7. At this time, the correction adjustment wheel 4 abuts against the lateral adjustment plate 5 through the rubber sleeve 401 to ensure that the movement of the end beam frame 2 will not deviate.

[0040] Compared with related technologies, the gantry-type sludge scraper correction device provided by this utility model has the following beneficial effects:

[0041] This invention guides the movement of the end beam frame 2 by having four correction adjustment wheels 4 on the top of the end beam frame 2 abut against the lateral adjustment plate 5, thus preventing the end beam frame 2 from deviating. It eliminates the need for frequent adjustments of the end beam frame 2 using sensors, reducing the manufacturing cost and failure rate of the equipment. At the same time, the correction adjustment wheels 4 are located above the end beam frame 2, with no obstructions above them, allowing them to be moved away from the lateral adjustment plate 5. This facilitates the replacement of the rubber sleeves 401 on the correction adjustment wheels 4, making the maintenance of the sludge scraper correction device easier.

[0042] The foregoing has shown and described the basic principles, main features, and advantages of this utility model. Those skilled in the art should understand that this utility model is not limited to the above embodiments. The embodiments and descriptions in the specification are merely illustrative of the principles of this utility model. Various changes and modifications can be made to this utility model without departing from its spirit and scope, and all such changes and modifications fall within the scope of the claimed utility model.
