Description

Technical Field

[0001] The invention belongs to the technical field of coking mechanical equipment, and in particular relates to a locking hook for a coke quenching vehicle. Background Art

[0002] The quenching car is a supporting equipment for a large coke oven. It usually runs on the track below the coke oven. It is used to receive the coke at about thousands of degrees Celsius discharged by the coke guide car, transport it to the quenching chamber for quenching, and finally transport the quenched coke to a designated location.

[0003] When the quenching car is in operation, it needs to be connected to the tractor by a hook. As the wear gap of the hook becomes larger and larger, the impact vibration between the electric locomotive and the quenching car also becomes larger and larger, which can easily cause the electric locomotive and the quenching car to decouple, causing danger and preventing normal production. Summary of the invention

[0004] In order to overcome the shortcomings of the above-mentioned prior art, the present invention provides a locking hook for a quenching car, which reduces the amplitude of the collision between the quenching car and the tractor, avoids the uncoupling caused by the collision, and at the same time extends the service life of the quenching car, ensuring the safe and stable operation of the production line.

[0005] In order to achieve the above object, the present invention adopts the following technical solutions:

[0006] A locking hook for a coke quenching vehicle comprises a telescopic rod, a screw rod, a support block, a rotating block, a buffer mechanism, a support rod and an electromagnet; the telescopic rod and the support block are fixedly connected to the coke quenching vehicle carriage, the screw rod is installed in the support block and is slidably connected to the support block, and the end of the telescopic rod is connected to the screw rod; two rotating blocks are hinged on the carriage and are located on both sides of the screw rod, one end of the rotating block is engaged with the screw rod, and the other end is connected to the buffer mechanism, the buffer mechanism is connected to one end of the support rod, and the electromagnet is fixed to the other end of the support rod; the telescopic rod is extended and retracted to drive the rotating block to rotate, thereby driving the two electromagnets to move away from and approach each other.

[0007] The telescopic rod is an electric telescopic rod.

[0008] The buffer mechanism includes a shell, a limit block, a connecting rod and a spring; the two ends of the spring are respectively connected to one end of the two limit blocks, the limit blocks are installed in the shell and are slidably connected to the shell, the other end of one limit block is connected to the rotating block through the connecting rod, and the other end of the other limit block is connected to the support rod through the connecting rod.

[0009] The magnetic poles of the two electromagnets at the ends close to each other are opposite.

[0010] Compared with the prior art, the present invention has the following beneficial effects:

[0011] 1. The present invention is provided with a buffer mechanism, which increases the buffering capacity of the coke quenching car, reduces the amplitude of the collision between the coke quenching car and the traction car, so that the wear gap will not be too large, avoids the occurrence of uncoupling caused by collision, increases the shock absorption of the entire coke quenching car, avoids the damage of the coke quenching car caused by sudden excessive traction force or collision, prolongs the service life of the coke quenching car, and ensures the safe and stable operation of the production line.

[0012] 2. The telescopic rod of the present invention adopts an electric telescopic rod, which is easy to control the telescopic operation and forms a controllable opening and closing structure with the electromagnet. The hooking and unhooking of the quenching vehicle and the tractor are realized by controlling the extension and retraction of the electric telescopic rod and the on and off of the electromagnet, which saves manual operation, avoids personal injury caused by high temperature, and increases safety. BRIEF DESCRIPTION OF THE DRAWINGS

[0013] Figure 1 It is a schematic diagram of the structure of the present invention;

[0014] Figure 2 for Figure 1 Enlarged view of point A.

[0015] In the figure: 1-carriage 2-telescopic rod 3-screw 4-support block 5-rotating block 6-support rod 7-electromagnet 8-roller 9-housing 10-connecting rod 11-limiting block 12-spring DETAILED DESCRIPTION

[0016] The specific implementation of the present invention will be further described below in conjunction with the accompanying drawings:

[0017] like Figure 1 As shown, a locking hook for a coke quenching vehicle comprises a telescopic rod 2, a screw rod 3, a support block 4, a rotating block 5, a buffer mechanism, a support rod 6 and an electromagnet 7. The telescopic rod 2 is an electric telescopic rod. The coke quenching vehicle comprises a carriage 1 and rollers 8, and is a movable coke quenching vehicle.

[0018] like Figure 2 As shown, the buffer mechanism includes a housing 9, two limit blocks 11, two connecting rods 10 and a spring 12. The two ends of the spring 12 are respectively connected to one end of the two limit blocks 11, the limit blocks 11 are installed in the housing 9 and are slidably connected to the housing 9, the other end of one limit block 11 is connected to the rotating block 5 through a connecting rod 10, and the other end of the other limit block 11 is connected to the support rod 6 through another connecting rod 10.

[0019] like Figure 1 As shown, the telescopic rod 2 and the support block 4 are both fixedly connected to the quenching car 1. The support block 4 is provided with a mounting hole adapted to the screw rod 3. The screw rod 3 is installed in the support block 4 through the mounting hole and is slidably connected to the support block 4. The end of the telescopic rod 2 is connected to the screw rod 3.

[0020] The rotating block 5 is L-shaped, the middle part of the rotating block 5 is hinged on the carriage 1, and the two rotating blocks 5 are located on both sides of the screw rod 3. One end of the rotating block 5 is engaged with the screw rod 3, and the other end is connected to the connecting rod 10 of the buffer mechanism.

[0021] The connecting rod 10 of the buffer mechanism is connected to one end of the support rod 6, and the electromagnet 7 is fixedly connected to the other end of the support rod 6. The ends of the two electromagnets 7 that are close to each other have opposite magnetic poles.

[0022] The working principle and working process of the present invention are as follows:

[0023] When in use, the telescopic rod 2 extends to drive the screw rod 3 to move forward, and the screw rod 3 moves forward to drive the rotating block 5 to rotate, so that the two support rods 6 drive the two electromagnets 7 to move away from each other. Then the tractor is moved close to the carriage 1, and a fixed hook is provided on the tractor. When the two vehicles reach a suitable distance, the telescopic rod 2 is started in the reverse direction, and the telescopic rod 2 is shortened to finally make the two electromagnets 7 close to each other and contact each other, and the fixed hook is hooked, and the two electromagnets 7 are energized, so that the two electromagnets 7 attract each other. At this time, the tractor moves to drive the support rod 6 together and drive the operation of the quenching car. At this time, the buffer mechanism increases the shock absorption of the entire quenching car to avoid damage to the quenching car caused by excessive traction or collision.

[0024] After arriving at the destination, the two electromagnets 7 are powered off at the same time, and the telescopic rod 2 is extended to separate the two electromagnets 7, thereby facilitating the uncoupling of the quenching vehicle and the tractor, thereby facilitating uncoupling, eliminating manual operation, avoiding injuries caused by high temperature and increasing safety.

[0025] The present invention is provided with a buffer mechanism, which increases the buffering capacity of the coke quenching car, reduces the amplitude of the collision between the coke quenching car and the traction car, ensures that the wear gap is not too large, avoids the decoupling caused by the collision, increases the shock absorption of the entire coke quenching car, avoids the damage of the coke quenching car caused by the sudden excessive traction force or collision, prolongs the service life of the coke quenching car, and ensures the safe and stable operation of the production line.

[0026] The telescopic rod 2 of the present invention adopts an electric telescopic rod, which is easy to control the telescopic operation and forms a controllable opening and closing structure with the electromagnet 7. The hooking and unhooking of the quenching vehicle and the tractor are achieved by controlling the extension and retraction of the electric telescopic rod 2 and the on and off of the electromagnet 7, which saves human operation, avoids personal injury caused by high temperature and increases safety.

[0027] The above description is only a preferred specific implementation manner of the present invention, but the protection scope of the present invention is not limited thereto. Any technician familiar with the technical field can make equivalent replacements or changes according to the technical scheme and inventive concept of the present invention within the technical scope disclosed by the present invention, which should be covered by the protection scope of the present invention.
