Description

Technical Field

[0001] This utility model relates to the technical field of hydraulic jacking equipment, specifically to a hydraulic jacking device for high wear-resistant bricks. Background Technology

[0002] In industrial kilns such as rotary kilns, hydraulic jacking devices are typically used to support the refractory bricks to ensure their stability and extend their service life. The core function of these devices is to apply stable pressure in a specific direction, ensuring the refractory bricks are tightly adhered to the kiln wall. Through a reliable hydraulic system and meticulous mechanical design, they solve the problem of dynamic compression of refractory linings under high-temperature and abrasive conditions. Their performance directly affects the service life of the refractory lining, the operating efficiency of the equipment, and maintenance costs.

[0003] Traditional hydraulic jacking devices have a fixed support angle and cannot adjust the tilt angle according to different needs. Furthermore, the jacking force during jacking is mostly adjusted by the support cylinder, which has poor adjustment accuracy and cannot meet the usage requirements of different scenarios. Therefore, we propose a high wear-resistant brick hydraulic jacking device. Utility Model Content

[0004] In view of the above-mentioned shortcomings of the existing technology, the present invention provides a hydraulic clamping device for high wear-resistant bricks, which can effectively solve the problems mentioned in the background art.

[0005] To achieve the above objectives, this utility model provides the following technical solution: This utility model provides a hydraulic clamping device for high wear-resistant bricks, including: The base has four brake wheels arranged in a rectangular pattern at its bottom, and a support cylinder for clamping the high wear-resistant bricks is provided on the top of the base. The adjustment mechanism includes a U-shaped seat fixedly connected to the top of the base, a connecting block installed on the side of the support cylinder near the U-shaped seat, a diagonal rod movably connected to the outside of the support cylinder via a pin, and an adjustment cylinder for adjusting the tilt angle of the support cylinder provided above the base. The contact mechanism includes a mounting plate movably connected to the telescopic end of the support cylinder. A clamping plate is provided on the side of the mounting plate away from the support cylinder. A contact plate is fixedly connected to the outer side of the clamping plate. Four second springs distributed in a rectangular pattern are fixedly connected to the side of the clamping plate near the mounting plate. Four second internal threaded holes distributed in a rectangular pattern are opened on the outer side of the mounting plate. Second external threaded tubes are threadedly connected to the inner side of the second internal threaded holes.

[0006] Preferably, the connecting block is movably connected to the inside of the U-shaped seat via a pin.

[0007] Preferably, the telescopic end of the adjusting cylinder is fixedly connected to a mounting block, and the inclined rod is movably connected to the outside of the mounting block via a pin.

[0008] Preferably, a fixing seat is installed on the outside of the adjusting cylinder, and the fixing seat is fixedly connected to the top of the base.

[0009] Preferably, four rectangularly distributed vertical rods are fixedly connected to the side of the top clamping plate near the mounting plate, and the other end of the vertical rods passes through the second external threaded tube and is slidably connected to the inner wall of the second external threaded tube.

[0010] Preferably, the mounting plate has two symmetrically distributed first internal threaded holes on its outer side. The inner wall of the first internal threaded hole is threaded with a first external threaded tube. One end of the first external threaded tube near the top plate is fixedly connected to a first spring, and the other end of the first spring is fixedly connected to a contact block.

[0011] Preferably, a limiting rod is fixedly connected to the side of the contact block near the first external threaded tube, and the other end of the limiting rod passes through the first external threaded tube and is slidably connected to the inner wall of the first external threaded tube.

[0012] The technical solution provided by this utility model has the following advantages compared with the known prior art: 1. By setting up a contact mechanism, this utility model allows for adjustment of the tightening force of the tightening device during the tightening operation by rotating the second external threaded tube, which moves within the second internal threaded hole. Furthermore, the second external threaded tube moves only slightly during rotation, resulting in more precise adjustment of the tightening force.

[0013] 2. By setting up an adjustment mechanism, this utility model allows the tilt angle of the support cylinder to be adjusted according to the actual tightening position before the tightening device is used, so that the hydraulic tightening device can perform tightening operations at different positions, making it more applicable.

Detailed Implementation

[0017] To make the objectives, technical solutions, and advantages of the embodiments of this utility model clearer, the technical solutions of the embodiments of this utility model will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some, not all, of the embodiments of this utility model. All other embodiments obtained by those skilled in the art based on the embodiments of this utility model without creative effort are within the scope of protection of this utility model.

[0018] The present invention will be further described below with reference to the embodiments. Example 1:

[0019] Reference Figure 1-2 This is the first embodiment of the present invention, which discloses a hydraulic clamping device for high wear-resistant bricks, comprising: The base 1 has four rectangular brake wheels 2 at its bottom and a support cylinder 3 for tightening the high wear-resistant bricks on its top. The brake wheel 2 is equipped with a braking device.

[0020] The adjustment mechanism 4 includes a U-shaped seat 402 fixedly connected to the top of the base 1, a connecting block 401 installed on the side of the support cylinder 3 near the U-shaped seat 402, a diagonal rod 403 movably connected to the outside of the support cylinder 3 via a pin, and an adjustment cylinder 405 for adjusting the tilt angle of the support cylinder 3 is provided above the base 1.

[0021] Specifically, the connecting block 401 is movably connected to the inside of the U-shaped seat 402 via a pin.

[0022] The tilt angle of the support cylinder 3 can be adjusted by the connecting block 401, the U-shaped seat 402 and the pin, so as to meet different clamping requirements.

[0023] Specifically, the telescopic end of the adjusting cylinder 405 is fixedly connected to the mounting block 404, and the diagonal rod 403 is movably connected to the outside of the mounting block 404 via a pin.

[0024] With the help of the mounting block 404, the support cylinder 3 can be connected to the adjustment cylinder 405 by the diagonal rod 403. When the adjustment cylinder 405 extends or retracts, the tilt angle of the support cylinder 3 can be adjusted by the mounting block 404 and the diagonal rod 403.

[0025] Specifically, a fixing seat 406 is installed on the outside of the adjusting cylinder 405, and the fixing seat 406 is fixedly connected to the top of the base 1.

[0026] The fixed base 406 can connect the adjusting cylinder 405 and the base 1 to ensure the stability of the adjusting cylinder 405. When the adjusting cylinder 405 extends, the tilt angle of the supporting cylinder 3 can be adjusted. Example 2:

[0027] Reference Figure 1-5 This is the second embodiment of the present invention, which differs from the first embodiment in that: The contact mechanism 5 includes a mounting plate 501 movably connected to the telescopic end of the support cylinder 3. A clamping plate 507 is provided on the side of the mounting plate 501 away from the support cylinder 3. A contact plate 506 is fixedly connected to the outside of the clamping plate 507. Four rectangularly distributed second springs 511 are fixedly connected to the side of the clamping plate 507 near the mounting plate 501. Four rectangularly distributed second internal threaded holes 509 are opened on the outside of the mounting plate 501. A second external threaded tube 503 is threadedly connected to the inside of the second internal threaded holes 509.

[0028] The extension of the support cylinder 3 pushes the mounting plate 501 to move until the contact plate 506 contacts the tightening position. At this time, the support cylinder 3 continues to extend until a suitable tightening force is reached and then stops, completing the tightening operation of the tightening area.

[0029] Specifically, four rectangularly distributed vertical rods 505 are fixedly connected to the side of the top plate 507 near the mounting plate 501. The other end of the vertical rods 505 passes through the second external threaded tube 503 and is slidably connected to the inner wall of the second external threaded tube 503.

[0030] The vertical rod 505 limits the movement trajectory of the top plate 507, ensuring that the top plate 507 can only move towards the side closer to the mounting plate 501 and away from the mounting plate 501.

[0031] Rotating the second external threaded tube 503 can compress the second spring 511 and adjust the tightening force.

[0032] Specifically, the mounting plate 501 has two symmetrically distributed first internal threaded holes 508 on its outer side. The inner wall of the first internal threaded hole 508 is threaded with a first external threaded tube 502. The first external threaded tube 502 is fixedly connected to one end near the top plate 507 with a first spring 504. The other end of the first spring 504 is fixedly connected to a contact block 512.

[0033] Rotating the first external threaded tube 502 allows for adjustment of its position under the action of the first internal threaded hole 508, until the contact block 512 contacts the top plate 507. This increases the number of springs between the top plate 507 and the mounting plate 501, compensating for fatigue in the second spring 511.

[0034] Specifically, a limiting rod 510 is fixedly connected to the side of the contact block 512 near the first external threaded tube 502, and the other end of the limiting rod 510 passes through the first external threaded tube 502 and is slidably connected to the inner wall of the first external threaded tube 502.

[0035] The movement trajectory of the contact block 512 can be limited by the limit rod 510, thereby ensuring that the contact block 512 is pushed to move when the top plate 507 moves, and the force of the pressing is increased under the reaction force of the first spring 504.

[0036] The remaining structure is the same as that in Example 1.

[0037] The workflow of this utility model is as follows: The base 1 is moved to the appropriate position by the brake wheel 2, and the mounting block 404 is moved by controlling the extension and retraction of the adjusting cylinder 405. The movement of the mounting block 404 is adjusted by the tilt angle of the supporting cylinder 3 by the inclined rod 403. After adjustment, start the support cylinder 3. The support cylinder 3 extends and pushes the mounting plate 501 to move until the contact plate 506 contacts the refractory bricks on the kiln that need to be tightened. At this time, reduce the extension speed of the support cylinder 3 until the tightening force is roughly adjusted to the required level. Then rotate the second external threaded tube 503 on the mounting plate 501 to compress the second spring 511 until the required clamping force is reached and then stop. At this point, the hydraulic clamping of the kiln refractory bricks is completed. When the second spring 511 becomes fatigued, rotate the first external threaded tube 502 until the contact block 512 contacts the mounting plate 501. At this time, the second spring 511 is compensated by the two first springs 504 to ensure the clamping force on the kiln. After the kiln is used, the second spring 511 is replaced.

[0038] The above embodiments are only used to illustrate the technical solutions of this utility model, and are not intended to limit it. Although this utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art should understand that modifications can still be made to the technical solutions described in the foregoing embodiments, or equivalent substitutions can be made to some of the technical features. Such modifications or substitutions will not cause the essence of the corresponding technical solutions to deviate from the protection scope of the technical solutions of the embodiments of this utility model.
