Description

Technical Field

[0001] The present application relates to the technical field of thickeners, and in particular to a novel thickener fixing device. Background Art

[0002] A thickener is typically constructed of concrete, wood, or welded metal plates, forming a shallow, cylindrical trough with a conical bottom. The upper section is a clarification zone, the lower section is a settling and compression zone, and a bottom outlet is provided for discharging the concentrated underflow slurry. The thickener is also equipped with a scraper (rake) to remove settled sludge toward the outlet. The thickener also features a feed pipe, a center tube, an overflow weir, and an overflow pipe, each used for feeding, dispersing the slurry, and discharging the supernatant.

[0003] The commonly used fasteners for fixing the thickener track with peripheral transmission are mainly plate fasteners and spring clip fasteners. The plate fastener locks the pressure plate on the embedded bolts through bolts, and the pressure plates are installed on both sides to press the track onto the concrete track foundation. After long-term operation of the plate fastener, the concrete track foundation will wear out, and the track will creep forward, causing the pressure plate and embedded bolts to break; the spring clip fastener (such as Figure 4 (As shown) After the spring clip pressure is reduced, the track will creep forward, and in severe cases, the embedded bolts will be torn.

[0004] Therefore, during actual use of the above-mentioned fixing fasteners, there is a problem that the embedded bolts are easily damaged, causing the track to move, thereby causing the dense machine wheel set to derail. Utility Model Content

[0005] In order to solve or partially solve the problems existing in the related art, the present application provides a novel thickener fixing device.

[0006] To achieve the above objectives, this application is implemented through the following technical solutions:

[0007] A novel thickener fixing device includes a rail having an I-shaped cross section, and the novel thickener fixing device further includes:

[0008] L-shaped bottom plate;

[0009] H-shaped pad fixed to the upper end of the L-shaped base plate;

[0010] A fastener plate provided on the end face of the H-shaped pad;

[0011] Among them, a limiting groove adapted to the track is opened in the middle of the upper end surface of the fastener plate. After the track is embedded in the limiting groove, the fastener plate is connected to both sides of the lower part of the track through elastic bars and fixing bolts.

[0012] Optionally, the length of the fastener plate is bent upward in the vertical direction at both ends to form a shoulder, and the shoulder abuts against one end of the elastic bar.

[0013] Optionally, two limiting protrusions are symmetrically provided on the fastener plate, and the distance between the two limiting protrusions is adapted to the width of the lower end of the track to form a limiting groove.

[0014] Optionally, the L-shaped bottom plate is provided with waist-shaped holes for allowing fixing bolts to pass through.

[0015] Optionally, both ends of the H-shaped pad and the fastener plate are provided with slots adapted to fit the fixing bolts, and the slots correspond one-to-one to the positions of the waist-shaped holes.

[0016] Optionally, the side plate of the L-shaped bottom plate has a circular hole, and a reinforcing bolt is passed through the circular hole.

[0017] Optionally, the spring bar is an I-type spring bar.

[0018] Beneficial effects of the present application: The spring bars used in the track fixing fasteners of the present application are easy to install and have strong clamping force. The spring bars and fixing bolts are not connected to the concrete foundation, so they are easy to replace. The L-shaped bottom plate is welded to the original embedded bolts, which makes full use of the structure of the original foundation. There is no need to drill holes to install anchor bolts, which causes less damage to the foundation. The bearing part at the bottom of the track is a fastener plate, which prevents the track from moving after the foundation is worn. The bottom of the track is embedded in the limiting groove opened on the fastener plate, which effectively prevents the lateral movement of the track. The clamping pressure of the spring bars and the pre-tightening force of the fixing bolts effectively prevent the vertical movement of the track. In this way, the problem of derailment of the dense machine wheelset is avoided.

[0032] The above description is merely an optional embodiment of the present application and is not intended to limit the present application.

[0033] In order to make the purpose, technical solutions and beneficial effects of the present application clearer, the preferred embodiments of the present application will be described in detail below with reference to the accompanying drawings to facilitate understanding by technical personnel.

[0034] Example 1:

[0035] See also Figure 1 and Figure 2 A novel thickener fixing device includes a track 4 having an I-shaped cross section. The novel thickener fixing device further includes:

[0036] L-shaped bottom plate 1;

[0037] An H-shaped pad 2 fixed to the upper end surface of the L-shaped base plate 1;

[0038] A fastener plate 3 provided on the upper end surface of the H-shaped backing plate 2;

[0039] Among them, a limiting groove adapted to the track 4 is opened in the middle of the upper end surface of the fastener plate 3. After the track 4 is embedded in the limiting groove, the fastener plate 3 is connected to the lower sides of the track 4 through the elastic bar 5 and the fixing bolt 6.

[0040] Specifically, the L-shaped base plate 1 is provided with two symmetrically positioned waist-shaped holes for the passage of fixing bolts 6. These two waist-shaped holes are aligned with the embedded bolts and welded in place. This allows the previously broken embedded bolts to be fully utilized during thickener track repair, minimizing the impact on the original foundation. Slots are provided at both ends of the H-shaped backing plate 2 and the fastener plate 3 to accommodate the fixing bolts 6. The slot width matches the width of the bolt head, and the slots correspond one-to-one with the waist-shaped holes.

[0041] The H-shaped backing plate 2 and fastener plate 3 are pre-aligned and welded. After the alignment is complete, the H-shaped backing plate 2 and fastener plate 3 are welded securely. The track 4 is placed within the retaining groove of the fastener plate 3. The fixing bolts 6 are inserted into the notches of the H-shaped backing plate 2 and fastener plate 3. The spring bars 5 and nuts are then used to complete the installation. Two spring bars 5 and two fixing bolts 6 are provided, symmetrically arranged about the track 4 to secure both sides of the track 4 and ensure uniform force distribution.

[0042] The spring bars 5 used in the track fixing fasteners of the present application are easy to install and have strong clamping force. The spring bars 5 and the fixing bolts 6 are not connected to the concrete foundation, which makes replacement easy. The L-shaped base plate 1 is welded to the original embedded bolts, making full use of the structure of the original foundation. No more drilling is required to install anchor bolts, which causes less damage to the foundation. The bearing part at the bottom of the track is the fastener plate 3, which prevents the track from moving after the foundation is worn. The bottom of the track 4 is embedded in the limiting groove opened on the fastener plate 3, which effectively prevents the track 4 from moving laterally. The clamping force of the spring bars 5 and the pre-tightening force of the fixing bolts 6 effectively prevent the track 4 from moving vertically. In this way, the problem of derailment of the dense machine wheelset is avoided.

[0043] Example 2:

[0044] See also Figure 2 and Figure 3 Based on the first embodiment, optionally, the length of the fastener plate 3 is bent upward in the vertical direction toward both ends to form a shoulder 7 , and the shoulder 7 abuts against one end of the elastic bar 5 .

[0045] Specifically, the spring bar 5 is integrally buckled onto the fastener plate 3 and the track 4 and is locked by a fixing bolt 6 , wherein one end of the spring bar 5 abuts against the shoulder 7 to prevent the spring bar 5 from shifting or falling off during the force application process.

[0046] At the same time, the abutment design of the shoulder 7 and the spring bar 5 allows these lateral forces to be more effectively transmitted to the rail fastener plate 3 and the foundation of the H-shaped pad 2, thereby reducing the lateral displacement and deformation of the track 4. Vertical forces (such as the weight of the thickener) are also transmitted to the fastener plate 3 and the H-shaped pad 2 through the spring bar 5 and shoulder 7. The design of the shoulder 7 helps to disperse these vertical forces, reducing the localized stress on the fastener plate 3, the H-shaped pad 2, and the foundation, thereby extending their service life.

[0047] Optionally, two limiting protrusions 8 are symmetrically provided on the fastener plate 3 , and the distance between the two limiting protrusions 8 is adapted to the width of the lower end of the track 4 to form a limiting groove.

[0048] Specifically, two limiting protrusions 8 are welded to the fastener plate 3, and the bottom of the track 4 is inserted into the limiting groove formed by the two limiting protrusions 8. By making the spacing between the two limiting protrusions 8 match the lower end width of the track 4, an effective limit is formed for the track 4, thereby improving the stability of the track 4.

[0049] Optionally, the side plates of the L-shaped bottom plate 1 are provided with circular holes, through which reinforcement bolts 9 are passed.

[0050] Specifically, two circular holes are provided, and correspondingly, two reinforcing bolts 9 are also provided, and the L-shaped bottom plate 1 is further secured by the reinforcing bolts 9 .

[0051] Optionally, the spring bar 5 is an I-type spring bar.

[0052] Specifically, the I-type spring bar, through its special bending and twisting deformation ability, can effectively maintain the clamping pressure on the track 4 for a long time. At the same time, the I-type spring bar has good elasticity and can absorb the impact energy generated by the thickener during operation, achieving the effect of shock absorption.

[0053] It should be noted that the structures and / or installation methods not detailed in this application are known to those skilled in the art in combination with common knowledge and / or existing technologies, and are not the focus of disclosure in this application and will not be further elaborated here.

[0054] Finally, it should be noted that the above preferred embodiments are only used to illustrate the technical solutions of the present application and are not limiting. Although the present application has been described in detail through the above preferred embodiments, those skilled in the art should understand that various changes can be made in form and details without departing from the scope defined by the claims of the present application; the dimensions of the drawings are not related to the specific objects, and the dimensions of the objects can be changed arbitrarily.
