Description

Technical Field

[0001] This application relates to the field of boiler sludge treatment technology, and in particular to a slide support device. Background Technology

[0002] Sludge incineration is a sludge treatment process. It uses an incinerator to heat and dry dewatered sludge, and then uses high temperature to oxidize the organic matter in the sludge, turning the sludge into a small amount of ash.

[0003] The sludge chamber slide seal in boiler sludge incineration is prone to wear and leakage. Despite replacing the seal and performing multiple maintenance and tightening operations, the leakage problem persists. Research has revealed that the sludge chamber packing seal is susceptible to deformation under pressure, leading to leakage. Analysis of the leakage location structure shows that the existing equipment slide drive mechanism is subjected to downward pressure from the slide itself, which can easily cause the lower sludge chamber packing seal to deform under pressure, creating gaps and resulting in leakage. Summary of the Invention

[0004] The purpose of this application is to provide a carriage support device, which provides auxiliary support for the operation of the carriage tie rod through the support component. The downward pressure transmitted by the carriage tie rod is offset by the support component, so that the carriage tie rod maintains a stable position during operation. This reduces the compression of the carriage sealing seat by external forces, reduces the amount of mud carried by the carriage tie rod during movement, reduces the amount of mud leakage from the carriage sealing seat and reduces its replacement frequency, thereby reducing the amount of manual mud cleaning work and improving the on-site construction environment.

[0005] The objective of this application is achieved through the following technical solution:

[0006] A carriage support device, comprising:

[0007] Base;

[0008] A mud bin, which is disposed on the base;

[0009] A carriage assembly is mounted on the mud bin, and the carriage assembly includes a carriage tie rod that movably passes through the mud bin;

[0010] A drive mechanism, connected to one end of the carriage tie rod, is used to drive the carriage tie rod to extend and retract relative to the mud bin;

[0011] A support assembly is installed at the connection between the carriage tie rod and the drive mechanism to support the telescopic movement of the carriage assembly.

[0012] Preferably, the carriage assembly further includes a carriage sealing seat disposed on the mud bin, and the carriage rod is movably installed through the carriage sealing seat; the mud bin has opposing inner and outer sides, the two ends of the carriage rod are respectively located on the inner and outer sides of the mud bin, and the outer end of the carriage rod is detachably connected to the output end of the drive mechanism.

[0013] Preferably, the carriage rod is pivotally connected to the output pin of the drive mechanism; a connecting sleeve is provided at the outer end of the carriage rod, a connector is provided at the output end of the drive mechanism, and a connecting pin is inserted between the connector and the connecting sleeve.

[0014] Preferably, the connecting sleeve has a U-shaped structure, and after the connecting sleeve and the connecting head are connected by the connecting pin, the connecting sleeve can rotate in the plane where the direction of gravity is located.

[0015] Preferably, the support assembly includes an upper fixing member, a lower fixing member, and a support screw;

[0016] The upper fixing member and the lower fixing member are located at the top and bottom of the connecting sleeve, respectively;

[0017] At least two support screws are provided, and they are located on both sides of the connecting sleeve respectively. The two ends of each support screw are connected to the upper fixing member and the lower fixing member respectively to clamp and fix the connecting sleeve.

[0018] Preferably, rollers are rotatably mounted at both ends of the lower fixing member, and the base is equipped with wheel tracks to support the movement of the rollers.

[0019] Preferably, the upper fixing member has a first hole at both ends, the lower fixing member has a second hole at both ends, each of the supporting screws passes through the first hole and the second hole respectively, and a fixing nut is installed at the end of each supporting screw.

[0021] Preferably, the upper fixing member is an L-shaped angle steel structure, the lower fixing member is a cylindrical structure, and the second hole is located on the outside of the roller.

[0022] Preferably, the base is provided with a support for mounting the drive mechanism, and the drive mechanism is a hydraulic cylinder.

[0023] Compared with the prior art, the beneficial effects of this application include at least the following:

[0024] The support components provide auxiliary support for the operation of the carriage tie rod. The downward pressure transmitted by the carriage tie rod is offset by the support components, so that the carriage tie rod maintains a stable position. This reduces the compression of the carriage sealing seat by external forces, reduces the amount of mud carried by the carriage tie rod during its movement, reduces the amount of mud leakage from the carriage sealing seat and reduces its replacement frequency, thereby reducing the amount of manual mud cleaning work and improving the on-site construction environment.

[0025] Furthermore, relying on the connection between the original equipment drive mechanism and the slide rail rod, a support assembly consisting of an upper fixing part, a lower fixing part, a support screw, and rollers is manufactured along the central axis of the slide rail rod. This assembly is then fixed to the connecting sleeve of the slide rail rod, ensuring that the support mechanism matches the center position of the slide rail rod. The support assembly provides auxiliary support for the operation of the slide rail rod, and the downward pressure transmitted by the slide rail rod is offset by this support assembly, keeping the slide rail rod in a stable position. This reduces the pressure exerted by external forces on the slide rail sealing seat, reduces the amount of mud carried during the movement of the slide rail rod, reduces the amount of mud leakage from the slide rail sealing seat and lowers its replacement frequency, thereby reducing the amount of manual mud cleaning work and improving the on-site construction environment.

[0029] Exemplary embodiments will now be described more fully with reference to the accompanying drawings. However, these exemplary embodiments can be implemented in many forms and should not be construed as limited to the embodiments set forth herein; rather, these embodiments are provided to make this application more complete and comprehensive, and to fully convey the concept of the exemplary embodiments to those skilled in the art. The same reference numerals in the drawings denote the same or similar structures, and therefore repeated descriptions of them will be omitted.

[0030] The terms used in this application to express position and direction are illustrated with the accompanying drawings, but may be changed as needed, and all such changes are included within the scope of protection of this application.

[0031] Reference Figures 1 to 2This application provides a carriage support device, including: a base 1, a mud chamber 2, a carriage assembly, a drive mechanism 3, and a support assembly.

[0032] The mud bin 2 is mounted on the base 1 and can contain boiler incineration sludge. Specifically, the mud bin 2 and the base 1 can be separate structures. The bottom of the mud bin 2 can be equipped with a steel support frame, and the base 1 can also be equipped with a steel support frame. The mud bin 2 and the steel support frame of the base 1 are connected and fixed to each other, preferably by bolts. The base 1 is provided with a support seat 101 for mounting the drive mechanism 3. The drive mechanism 3 is fixedly mounted on the support seat 101. The support seat 101 can be fixed to the base 1 by bolts, welding, or integral molding. The drive mechanism 3 can be a hydraulic cylinder or other existing drive devices, and no single limitation is made here.

[0033] The slide assembly is installed on the mud bin 2. Specifically, the slide assembly is installed on the mud discharge side of the mud bin 2 and is located above the base 1. The slide assembly includes a slide rod 5, which moves through the mud bin 2. The slide assembly may also include a slide sealing seat 4 disposed on the mud bin 2. The slide rod 5 moves through the slide sealing seat 4, which prevents sludge from being carried out of the mud bin 2 when the slide rod 5 moves. The mud bin 2 has opposing inner and outer sides. The two ends of the slide rod 5 are located on the inner and outer sides of the mud bin 2, respectively. The outer end of the slide rod 5 is detachably connected to the output end of the drive mechanism 3. When the drive mechanism 3 operates, it can drive the slide rod 5 to reciprocate and extend relative to the mud bin 2.

[0034] The drive mechanism 3 is connected to one end of the carriage tie rod 5. Specifically, the drive mechanism 3 is connected to the outer end of the carriage tie rod 5 located in the mud chamber 2, and is used to drive the carriage tie rod 5 to extend and retract relative to the mud chamber 2.

[0035] A support assembly is installed at the connection between the carriage tie rod 5 and the drive mechanism 3 to support the telescopic movement of the carriage assembly. Preferably, the support assembly includes an upper fixing member 7, a lower fixing member 8, and a support screw 9. Specifically, the upper fixing member 7 and the lower fixing member 8 are located at the top and bottom of the connecting sleeve 501, respectively. The upper fixing member 7 has first holes at both ends, and the lower fixing member 8 has second holes at both ends. At least two support screws 9 are provided, located on both sides of the connecting sleeve 501. Each support screw 9 is connected to both ends of the upper fixing member 7 and the lower fixing member 8 to clamp and fix the connecting sleeve 501. Thus, the upper fixing member 7, the lower fixing member 8, and the support screw 9 cooperate to form a frame-like fixing structure, supporting and limiting the movement direction of the connecting sleeve 501, reducing or preventing the carriage tie rod 5 from swinging up and down or left and right, reducing the force exerted by the carriage tie rod 5 on its connection with the mud chamber 2, preventing gaps at the connection between the carriage tie rod 5 and the mud chamber 2, thereby mitigating or preventing mud leakage at the connection. It should be noted that the support assembly in this application uses two support screws 9 as an example for illustration.

[0036] Specifically, each support screw 9 has its two ends passing through the corresponding first hole and second hole, and each end of the support screw 9 is equipped with a fixing nut to connect the upper fixing member 7 and the lower fixing member 8. Thus, the upper fixing member 7, the lower fixing member 8 and the support screw 9 can clamp and fix the slide rail rod 5, thereby providing support for the slide rail rod 5, reducing or avoiding the interaction between the slide rail rod 5 and the mud bin 2, and mitigating or avoiding mud leakage.

[0037] In a preferred embodiment, the carriage rod 5 is pivotally connected to the output pin of the drive mechanism 3; a connecting sleeve 501 is provided on the outer end of the carriage rod 5, and a connector 301 is provided on the output end of the drive mechanism 3, with a connecting pin 6 inserted between the connector 301 and the connecting sleeve 501. Preferably, the connector 301 is a fisheye connector, located inside the connecting sleeve 501. The connecting pin 6 passes through the through hole of the fisheye connector and is connected to the connecting sleeve 501 at both ends, thus achieving a pivotal connection between the carriage rod 5 and the output end of the drive mechanism 3. This pivotal connection allows the connector 301 and the connecting sleeve 501 to maintain a certain degree of freedom of movement, preventing the force caused by the misalignment between the output end of the drive mechanism 3 and the carriage rod 5 during a rigid connection from being applied at the connection between the carriage rod 5 and the mud chamber 2. This results in less resistance for the carriage rod 5 as it passes through the mud chamber 2, reducing mud leakage.

[0038] In a preferred embodiment, the connecting sleeve 501 has a U-shaped structure. After being connected to the connecting head 301 via the connecting pin 6, the connecting sleeve 501 can rotate within the plane of gravity. Specifically, the U-shaped connecting sleeve 501 has pre-drilled or opened pin holes (not shown in the figure) on both sides for the connecting pin 6 to pass through. After passing through the corresponding pin holes, the connecting pin 6 is secured by a pin catch or pin cover to prevent it from falling off. It should be noted that, in this preferred embodiment, the connecting sleeve 501 can specifically be configured as a U-shaped plate structure, with pin holes (not shown in the figure) located at both ends of the U-shaped plate-shaped connecting sleeve 501.

[0039] In a preferred embodiment, the upper fixing member 7 is preferably an L-shaped angle steel structure, and the lower fixing member 8 is preferably a cylindrical structure. The second hole is located on the outer side of the roller 801. The use of an L-shaped angle steel structure for the upper fixing member 7 ensures that the contact area between the upper fixing member 7 and the connecting sleeve 501 is planar, effectively preventing the upper fixing member 7 from moving along the connecting sleeve 501. This also correspondingly improves the stability of the fit between the cylindrical lower fixing member 8 and the connecting sleeve 501, and enhances the stability and reliability of the fit between the overall frame-shaped support assembly and the carriage tie rod 5.

[0040] It should be noted that the connecting sleeve 501 can be clamped and fixed using the upper fixing member 7, the lower fixing member 8, and the support screw 9. By clamping and fixing the connecting sleeve 501 at the end of the slide rail rod 5, the support effect of the slide rail rod 5 can be better achieved, maintaining good straightness of the slide rail rod 5 during its telescopic movement, and without affecting the range of motion of the slide rail rod 5 relative to the mud chamber 2. Thus, this frame-shaped support assembly, by positioning one end of the slide rail rod 5, ensures that the slide rail rod 5 moves horizontally along its central axis during its reciprocating telescopic movement. This reduces the pressure exerted on the slide rail sealing seat 4 by external forces, keeps the slide rail rod 5 in a stable position, alleviates the problem of deformation of the slide rail sealing seat 4 under pressure, extends the service life of the slide rail sealing seat 4, and significantly improves the sealing connection effect between the slide rail rod 5 and the slide rail sealing seat 4.

[0041] As a preferred embodiment, rollers 801 are rotatably mounted at both ends of the lower fixing member 8, and a wheel track 10 is installed on the base 1 to support the movement of the rollers 801. Preferably, the rollers 801 have a double-wheel structure to improve the stability of their movement, which in turn improves the stability of the frame-shaped support assembly for the telescopic movement of the carriage tie rod 5. The upper surface of the wheel track 10 has a groove (not shown in the figure), along which the rollers 801 can roll. The wheel track 10 is preferably a channel steel walkway, with the groove formed on its upper surface. The wheel track 10 can be bolted to the base 1 for easy replacement and maintenance of the base 1.

[0042] It should be noted that the central axis of roller 801 coincides with that of lower fixed member 8 to ensure the stability of roller 801 during rotation. During the installation of roller 801, upper fixed member 7, lower fixed member 8, and support screw 9 must first be installed and fixed on connecting sleeve 501. The support assembly consisting of upper fixed member 7, lower fixed member 8, and support screw 9 is then fixed using corresponding fixing nuts. As the position of lower fixed member 8 is fixed, the position of roller 801 installed on lower fixed member 8 is also fixed. The wheel track 10 is then laid on base 1 according to the movement trajectory of roller 801. If there is a gap between the upper surface of wheel track 10 and roller 801, a shim or other support element can be added to the bottom of lower fixed member 8 to make the upper surface of lower fixed member 8 contact roller 801.

[0043] Of course, the height between the lower fixing part 8 and the base 1 can also be measured in advance to ensure that the sum of the radius length of the roller 801 and the height of the wheel track 10 is equal to the height between the lower fixing part 8 and the base 1. The specific size of the radius of the roller 801 and the height of the wheel track 10 can be adjusted accordingly.

[0044] As an example:

[0045] Specifically, in one example, when the radius of roller 801 is determined, after the upper fixing member 7, lower fixing member 8, and support screw 9 are clamped and fixedly installed on the carriage pull rod 5, the position of roller 801 is fixed. Subsequently, a wheel track 10 of corresponding height is installed on the base 1 along the travel path of roller 801. After the wheel track 10 is installed on the base 1, the top surface of roller 801 and wheel track 10 are in contact, realizing the support effect of the frame-shaped travel support assembly composed of upper fixing member 7, lower fixing member 8, support screw 9, and roller 801 at the connection between carriage pull rod 5 and drive mechanism 3. It should be noted that the height of the corresponding wheel track 10 is the difference between the distance between the central axis of lower fixing member 8 and roller 801 coinciding with the upper surface of base 1 and the radius of roller 801.

[0046] Specifically, in another example, when the height of the wheel track 10 is determined, rollers 801 with corresponding radius sizes are selected and installed at both ends of the lower fixing member 8. After the upper fixing member 7, lower fixing member 8, support screw 9, and clamping fixing are installed on the carriage pull rod 5, the position of the rollers 801 is fixed. Subsequently, the wheel track 10 is installed on the base 1 along the travel path of the rollers 801. After the wheel track 10 is installed on the base 1, the rollers 801 are in contact with the top surface of the wheel track 10, realizing the support effect of the frame-shaped travel support assembly composed of the upper fixing member 7, lower fixing member 8, support screw 9, and rollers 801 at the connection between the carriage pull rod 5 and the drive mechanism 3. It should be noted that the radius size of the rollers 801 mentioned above is the difference between the distance between the central axis of the lower fixing member 8 and the roller 801 coinciding and the upper surface of the base 1 and the height of the wheel track 10.

[0047] In the first specific example, when the upper surface of the wheel track 10 is provided with a wheel groove, the height of the wheel track 10 should be understood as the height of the bottom of the wheel groove of the wheel track 10. The height of the bottom of the wheel groove of the wheel track 10 is the difference between the distance between the central axis of the lower fixing member 8 and the roller 801 and the upper surface of the base 1 and the radius of the roller 801. In the second specific example, the radius of the roller 801 is the difference between the distance between the central axis of the lower fixing member 8 and the roller 801 and the upper surface of the base 1 and the height of the bottom of the wheel groove of the wheel track 10.

[0048] When the wheel track 10 adopts the above two specific example settings, the connection and fixing method between the wheel track 10 and the base 1 can be not only bolted, but also welded, or other suitable forms in the prior art. No single limitation is made here.

[0049] Therefore, relying on the connection between the original equipment drive mechanism 3 and the slide rail rod 5, a frame-shaped traveling support assembly consisting of an upper fixing part 7, a lower fixing part 8, a support screw 9, and a roller 801 is made along the central axis of the slide rail rod 5. This assembly is fixed to the connecting sleeve 501 of the slide rail rod 5, so that the frame-shaped traveling support mechanism is matched with the center position of the slide rail rod 5. The frame-shaped traveling support assembly provides auxiliary support for the operation of the slide rail rod 5. The downward pressure transmitted by the slide rail rod 5 is offset by the frame-shaped traveling support assembly, so that the slide rail rod 5 maintains a stable position. This reduces the compression of the slide rail sealing seat 4 by external forces, reduces the amount of mud carried by the slide rail rod 5 during its movement, reduces the amount of mud leakage from the slide rail sealing seat 4 and reduces its replacement frequency, thereby reducing the amount of manual mud cleaning work and improving the on-site construction environment.

[0050] Although embodiments of this application have been shown and described above, it is understood that the above embodiments are exemplary and should not be construed as limiting this application. Those skilled in the art can make changes, modifications, substitutions and variations to the above embodiments within the scope of the application without departing from the principles and spirit of this application, and all such changes should fall within the protection scope of the claims of this application.
