Description

Technical Field

[0001] This utility model relates to the field of dry quenching furnace technology, and in particular to a brick delivery device for dry quenching furnace construction. Background Technology

[0002] The dry quenching furnace is the core equipment in the dry quenching coke process, mainly used for heat exchange between red-hot coke and cold inert gas. During this process, the red-hot coke is quenched, and the cold inert gas is heated. The dry quenching furnace is constructed manually using stacking and masonry. The manhole masonry of the cooling section is the part that directly contacts the high-temperature coke inside the furnace. It is divided into three layers from the inside out, serving as a wear-resistant working layer, a heat-insulating layer, and a thermal insulation layer, effectively isolating the exchange of gases and heat between the inside and outside of the furnace. Therefore, the construction quality of the dry quenching furnace directly determines the service life of the cooling section. To improve construction speed, external brick delivery devices are often used to transport the stacked bricks. However, existing delivery devices have some problems in use.

[0003] 1. Existing brick delivery devices have a large overall structure, which causes some troublesome problems during transportation. Furthermore, the long and difficult-to-fold delivery devices are also prone to bumps and damage during transportation, greatly reducing their flexibility.

[0004] 2. In the existing brick delivery device, due to the lack of relevant safety protection measures in the lifting process, the bricks are prone to sudden drops due to damage to the lifting mechanism caused by excessive weight. Such situations can lead to safety accidents, thus reducing the safety of the brick delivery device. Utility Model Content

[0005] The purpose of this invention is to address the shortcomings of existing technologies by proposing a brick delivery device for dry quenching furnace construction.

[0006] To achieve the above objectives, the present invention adopts the following technical solution:

[0007] A brick delivery device for dry quenching furnace construction includes two parallel first I-shaped channel steels. A second I-shaped channel steel is hinged to the top outer wall of the first I-shaped channel steels via a hinge. Equally spaced first connecting shafts are welded between the two parallel first I-shaped channel steels. Equally spaced second connecting shafts are welded between the second I-shaped channel steels. A fixed pulley is rotatably mounted in the middle of the second connecting shafts. A winding roller is rotatably mounted at the bottom of the first I-shaped channel steels, and a traction steel rope is attached to the winding roller. The other end of the traction steel rope is connected to a stacking frame. A reinforcing base is welded to the bottom outer wall of the stacking frame, and guide wheels are provided on the side of the reinforcing base.

[0008] As a further embodiment of this utility model: limit blocks are welded to the outer walls of the first I-shaped channel steel and the second I-shaped channel steel on opposite sides, and a reinforcing block is inserted and fixed between the two limit blocks. The limit blocks and the reinforcing block are fixed together by fastening bolts.

[0009] As a further improvement of this utility model: the outer walls of the first I-shaped channel steel and the second I-shaped channel steel on opposite sides are both provided with a fixed slot, and a C-shaped plug is inserted into the inner wall of the fixed slot.

[0010] As a further embodiment of this utility model: a worm gear is welded to one side of the outer wall of the take-up roller, and a worm is engaged with the worm gear, the worm being connected to a servo motor.

[0011] As a further improvement of this utility model: the bottom outer wall of the first I-shaped channel steel is welded with an anti-slip pad, and the bottom outer wall of the anti-slip pad is adhered with an anti-slip mat.

[0012] As a further improvement of this utility model: the two sets of guide wheels are closely attached to the outer wall of the first I-shaped channel steel, and the guide wheels and the first I-shaped channel steel form a rolling fit.

[0023] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments.

[0024] Example 1:

[0025] A brick delivery device for a dry quenching furnace, in this embodiment, as follows: Figure 1-4As shown, the structure includes two parallel I-shaped channel steels 1. A second I-shaped channel steel 2 is hinged to the top outer wall of the first I-shaped channel steel 1 via a hinge. A first connecting shaft 3 is welded between the two parallel first I-shaped channel steels 1 at equal intervals. A second connecting shaft 4 is welded between the second I-shaped channel steels 2 at equal intervals. A fixed pulley 10 is rotatably installed in the middle of the second connecting shaft 4. A winding roller 11 is rotatably installed at the bottom of the first I-shaped channel steel 1. A traction steel rope 12 is attached to the winding roller 11. The other end of the traction steel rope 12 is connected to a stacking frame 13. A reinforcing base frame 14 is welded to the bottom outer wall of the stacking frame 13. A guide wheel 15 is provided on the side of the reinforcing base frame 14.

[0026] By setting a connecting hinge in the middle of the first I-shaped channel steel 1 and the second I-shaped channel steel 2, and cooperating with a detachable reinforcing block 6 on the side, the delivery device can be folded, which can greatly reduce the space occupied, thereby facilitating the disassembly of the delivery device and improving the convenience and safety of the transfer process.

[0027] The first I-shaped channel steel 1 and the second I-shaped channel steel 2 are both welded with limit blocks 5 on opposite outer walls, and a reinforcing block 6 is inserted and fixed between the two limit blocks 5. The limit blocks 5 and the reinforcing block 6 are fixed by fastening bolts 7. The first I-shaped channel steel 1 and the second I-shaped channel steel 2 are both provided with a through-hole fixing slot 8 on opposite outer walls, and a C-shaped plug 9 is inserted and installed on the inner wall of the fixing slot 8.

[0028] A worm gear 16 is welded to one side of the outer wall of the take-up roller 11, and a worm 17 is engaged with the worm gear 16. The worm 17 is connected to a servo motor 18.

[0029] The bottom outer wall of the first I-shaped channel steel 1 is welded with an anti-slip pad 19, and the bottom outer wall of the anti-slip pad 19 is bonded with an anti-slip mat.

[0030] During the process of lifting and delivering bricks, the winding roller 11 is used to wind up the traction steel rope 12, thereby lifting the stacking frame 13 carrying bricks. This allows for rapid lifting of the bricks. During the lifting process, the worm gear 17 drives the worm wheel 16 to rotate, which in turn drives the winding roller 11 to rotate while also achieving self-locking to prevent sudden falls during the lifting process, thus improving safety.

[0031] In this embodiment, the first I-shaped channel steel 1 and the second I-shaped channel steel 2 are first unfolded and placed on the same straight line. Then, the reinforcing block 6 is inserted between the two limiting blocks 5 on both sides. Then, the first I-shaped channel steel 1 and the second I-shaped channel steel 2 are reinforced and connected using the fastening bolts 7. After that, the C-shaped plug 9 is inserted into the fixed slot 8 to complete the assembly. After the traction steel rope 12 is passed through the fixed pulley 10 at the top and connected to the stacking frame 13, the assembled brick delivery device is placed against the site to be delivered. The bricks to be delivered are placed on top of the stacking frame 13. Then, the servo motor 18 at the bottom is started. The servo motor 18 drives the worm gear 17 to rotate, which in turn drives the worm wheel 16 to rotate. The winding roller 11 rotates to wind up the traction steel rope 12, thereby lifting the stacking frame 13 and delivering the bricks.
