Description

Technical Field

[0001] This utility model relates to the field of tunnel kiln technology, and in particular to a tunnel kiln shuttle car hook device. Background Technology

[0002] A tunnel kiln is generally a long, straight tunnel with fixed walls and an arched ceiling on both sides and top. Kiln cars run on tracks laid at the bottom. The combustion equipment is located on both sides of the middle of the tunnel kiln, forming a fixed high-temperature zone—the firing zone. The high-temperature flue gas generated by combustion flows along the tunnel towards the kiln head under the action of the chimney or induced draft fan at the front of the tunnel kiln, gradually preheating the products entering the kiln. This section constitutes the preheating section of the tunnel kiln.

[0003] The tunnel kilns currently in use have tracks laid on the ground, with blanks to be fired placed at intervals on the tracks by car bodies. The car bodies then carry the blanks into the tunnel kiln for firing.

[0004] Chinese patent application number CN201620940689.0 discloses a tunnel kiln car, including a metal frame and a heat-resistant layer disposed on the frame. The heat-resistant layer has heat-insulating structures on both sides that match the sand sealing groove of the tunnel kiln. The surface of the heat-insulating structure is covered with an asbestos layer, which is composed of multiple hinged asbestos sheets spliced ​​together. The asbestos sheets are connected to the heat-insulating structure by springs.

[0005] Further research by the applicant revealed that during the process of transporting billets into the tunnel kiln in batches, adjacent kiln cars often piled up together at the end, resulting in uneven heating of the billets in the tunnel kiln and affecting the firing and shaping of the billets. The reason for this was the lack of a device to separate and limit the kiln cars, which affected the firing quality of the products.

[0006] Therefore, it is necessary to provide a tunnel kiln shuttle car and hook car device to solve the above-mentioned technical problems. Utility Model Content

[0007] This utility model provides a shuttle car and hook car device for tunnel kilns, which solves the problems in the background art.

[0008] To solve the above-mentioned technical problems, this utility model provides a tunnel kiln shuttle car hook device, including a track, a mounting plate, and a car body. The car body slides on the track, and the mounting plate is fixed inside the track. A vertical plate is vertically installed at the edge of the top surface of the mounting plate. A bidirectional screw is movably installed on the surface of the vertical plate. One end of the bidirectional screw is driven by a handwheel. A sliding rod is installed on the surface of the vertical plate on one side of the bidirectional screw. Threaded sleeves are symmetrically spirally connected to the surface of the bidirectional screw. A sliding sleeve is slidably sleeved on the surface of the sliding rod. The threaded sleeve and the sliding sleeve are fixed by a connecting rod. A first mounting seat is provided on the top surface of the two sliding sleeves. An adjusting rod is movably installed inside the first mounting seat. A second mounting seat is movably provided at the other end of the adjusting rod. A top plate is provided at one end of the second mounting seat. A hook rod is vertically installed on the top surface of the top plate. The coordinated use of the mounting plate, vertical plate, double-acting screw, handwheel, threaded sleeve, sliding rod, sliding sleeve, first mounting seat, second mounting seat, adjusting rod, top plate, and hook rod facilitates the restriction of two adjacent car bodies entering the tunnel kiln. After the car bodies move into the tunnel through the cooperation of the track, the distance between the two adjacent car bodies is adjusted. Then, the double-acting screw is manually rotated by the handwheel. Under the action of the double-acting screw, the sliding sleeve moves on the sliding rod through the cooperation of the threaded sleeve and connecting rod. Then, with the cooperation of the first mounting seat, second mounting seat, and top plate, the hook rod moves upward, thus contacting the two adjacent car bodies end to end, thereby restricting their movement. This method is simple to operate, improves stability, and ensures that the car bodies moving towards the tunnel kiln maintain a certain distance, avoiding uneven heating of the billet caused by the car bodies touching each other.

[0009] Preferably, the inner diameter of the sliding sleeve is equal to the outer diameter of the sliding rod. By setting the outer diameter of the sliding rod to be equal to the inner diameter of the sliding sleeve, the stability of the sliding sleeve sliding on the surface of the sliding rod is improved.

[0010] Preferably, the slide bar is provided in two sets, and the two sets of slide bars are symmetrically installed on the surface of the vertical plate about the bidirectional lead screw. By providing two sets of slide bars, it is convenient to control the two hook rod drives at the same time, so that they limit the front and rear of the two adjacent car bodies. This method is simple to operate and can improve the efficiency of its limiting.

[0011] Preferably, multiple mounting plates are provided, and the multiple mounting plates are installed at equal intervals inside the track. By providing multiple mounting plates, it is convenient to limit the hooking of multiple car bodies and improve the stability of multiple car bodies inside the tunnel kiln.

[0012] Preferably, a clearance hole is provided through the outer surface of the track. By providing the clearance hole, it is easy to allow the handwheel to be moved aside, making it convenient for the operator to operate the handwheel.

[0013] Preferably, the vertical plate has fixing holes on its surface, and the vertical plate is fixed to the track by fasteners passing through the fixing holes. By providing fixing holes, it is easy to fix the mounting plate to the track by fasteners.

[0014] Compared with related technologies, the tunnel kiln shuttle car hook device provided by this utility model has the following beneficial effects:

[0015] Compared with existing technologies, this tunnel kiln shuttle car hook device, through the coordinated use of mounting plates, vertical plates, double-acting screws, handwheels, threaded sleeves, sliding rods, sliding sleeves, first mounting seats, second mounting seats, adjusting rods, top plates, and hook car rods, facilitates the limiting of two adjacent car bodies entering the tunnel kiln. After the car bodies move into the tunnel through the cooperation of the track, the distance between the two adjacent car bodies is adjusted. Then, the double-acting screw is manually rotated by the handwheel. Under the action of the double-acting screw, the sliding sleeve moves on the sliding rod through the cooperation of the threaded sleeve and connecting rod. Then, with the cooperation of the first mounting seat, second mounting seat, and top plate, the hook car rod moves upward, thus contacting the two adjacent car bodies end to end, thereby limiting their movement. This method is simple to operate, improves its stability, and ensures that the car bodies moving towards the tunnel kiln maintain a certain distance, avoiding uneven heating of the billet caused by the car bodies touching each other.
