TECHNICAL FIELD
[0001] The utility model relates to the field of coking industrial production and processing equipment, and particularly relates to a mobile dust removal valve safety device. BACKGROUND
[0002] In coking industrial production, the mobile dust removal of the coke barrier car plays a key role, and the safe use of the mobile dust removal valve is an important link to ensure the smooth production. The prior art installs related devices on the mobile device to ensure the safe and normal operation of the auxiliary equipment, which is of great significance to maintain the continuity and stability of production.
[0003] However, the detection device installed in the prior art has only a single limit stopper. During use, the single limit stopper may fall off the connection line, and when the device runs to the limit stopper, the limit stopper will always send a normal signal, causing the device to continue to run, resulting in damage to the device and the rear part, which requires maintenance and replacement of the damaged parts, thereby seriously affecting the production progress of the coking enterprise, causing production interruption, efficiency reduction and other adverse effects, and causing economic losses to the enterprise. CONTENT OF THE UTILITY MODEL
[0004] Therefore, the utility model provides a mobile dust removal valve safety device, which can prevent single limit stopper signal errors and production accidents by arranging two limit stoppers vertically on both sides of the dust removal valve, and the angle iron on the device simultaneously contacts the two limit stoppers to perform the next operation.
[0005] To solve the above technical problems, the utility model provides a mobile dust removal valve safety device, which comprises a mounting piece mounted on a coke barrier car and two limit stoppers vertically arranged and connected to the mounting piece. The output end of the limit stopper is located above the adjacent equipment of the coke barrier car, and an angle iron is fixed on the adjacent equipment to collide with the output end of the limit stopper to complete signal transmission. Only when the two limit stoppers arranged vertically simultaneously receive the signal can the next operation be performed.
[0006] The mounting piece comprises an L-shaped bottom plate, one end of which is stably connected to the coke barrier car by welding, bolt connection or other methods to ensure the firmness of the connection. The limit stopper is provided with a clamping groove on the side adjacent to the L-shaped bottom plate, which is used to place the other end of the L-shaped bottom plate to preliminarily position the limit stopper and the mounting piece.
[0007] The L-shaped bottom plate away from the limit stopper is symmetrically connected with a connecting rod, and the end of the connecting rod is provided with a transverse limiting rod. The transverse limiting rod can effectively prevent the clamping groove from falling off the L-shaped bottom plate, and can maintain the connection state of the limit stopper and the mounting piece even when the coke barrier car runs with vibration and shaking.
[0008] The connecting rod bottom is provided with a push rod, when the limit stop needs to be disassembled and maintained, the separately arranged connecting rods can be closed by the push rod, the limit rod is moved away from the both ends of the clamping groove, then the limit stop is lifted upward and taken off from the mounting piece, so that the limit stop can be conveniently replaced.
[0009] The L-shaped bottom plate is provided with a sliding groove, and the connecting rod is provided with a sliding block which can slide in the sliding groove.
[0010] The adjacent connecting rods are provided with a rebounding piece, and the rebounding piece is a spring in the embodiment.
[0011] The beneficial effects of the above technical scheme of the utility model are as follows:
[0012] 1. Double limit stop design: a plurality of vertically arranged limit stops are arranged at both ends of the dust removal valve, and the minimum number is two.
[0013] 2. L-shaped bottom plate connection mode: the mounting piece adopts an L-shaped bottom plate, one end of which is connected to the coke guide car stably through welding, bolt connection or other modes, so that the mounting piece will not be loose when the coke guide car runs and shakes, and a reliable foundation is provided for the stable installation of the limit stop.
[0014] 3. Clamping groove and L-shaped bottom plate cooperation positioning: the limit stop is provided with a clamping groove on one adjacent side, and the other end of the L-shaped bottom plate is placed in the clamping groove, so as to preliminarily position the limit stop and the mounting piece, ensure the accurate installation position of the limit stop, and enable the limit stop to normally play a role.
[0015] 4. Transverse limit rod anti-falling: the connecting rod end of the L-shaped bottom plate away from the limit stop is provided with a transverse limit rod, which can effectively prevent the clamping groove from falling off the L-shaped bottom plate, maintain the connection state of the limit stop and the mounting piece, avoid the separation of the limit stop and the mounting piece due to the shaking of the coke guide car, and make the safety device invalid.
[0016] 5、Dial lever facilitates disassembly and maintenance: The dial lever is arranged at the bottom of the connecting rod. When the limit stop needs to be disassembled and maintained, the operator brings the separately arranged connecting rods together through the dial lever, so that the transverse limit rod is away from both ends of the clamping groove, the limiting is released, at this time the limit stop is lifted upward and can be taken off from the mounting piece, thereby improving the efficiency of equipment maintenance.
[0017] 6、Chute and sliding block auxiliary movement: The chute is arranged on the L-shaped bottom plate, and the sliding block is arranged on the connecting rod and can slide in the chute. When the connecting rods are brought together through the dial lever, the sliding block slides in the chute, so that the connecting rod can move horizontally more stably, preventing the connecting rod from being stuck during movement and ensuring smooth operation.
[0018] 7、Rebound piece enhances stability: The rebound piece (such as a spring) is arranged between the adjacent connecting rods. The sliding rod is arranged on the connecting rod and penetrates the rebound piece. When the connecting rod is displaced by external force, the elastic force generated by the rebound piece promotes the connecting rod to return to the initial position, preventing the limit stop from moving upward and falling off, and further enhancing the stability and reliability of the safety device.

[0023] In order to make the purpose, technical scheme and advantages of the embodiments of the utility model clearer, the following will combine the drawings of the embodiments of the utility model to make the purpose, technical scheme and advantages of the embodiments of the utility model clearer. Figures 1-3 The technical scheme of the embodiments of the utility model is described clearly and completely. Obviously, the described embodiments are part of the embodiments of the utility model, not all the embodiments. Based on the described embodiments of the utility model, all other embodiments obtained by those skilled in the art belong to the scope of protection of the utility model.
[0024] As Figure 1 , 2 , 3:
[0025] The embodiment provides a mobile dust removal valve safety device, which comprises a mounting piece 2 installed on a coke guide car and a position limiter 1 connected to the mounting piece 2, the position limiter 1 is a core component for realizing the safety function, is vertically arranged on the mounting piece 2, and the number is two, the position limiter 1 and an angle iron on a moving piece are used in cooperation, when the angle iron moves from one end to the position of the position limiter 1, the angle iron collides with the two position limiters 1 vertically arranged at the front end at the same time, when normal signals of the two position limiters 1 are generated, the angle iron continues to move to the other side position limiter 1, when the rear end position limiter 1 is collided, the same two position limiters 1 simultaneously generate normal signals, and the equipment continues the next step operation.
[0026] As shown in Figure 1 , 2 , 3:
[0027] The mounting piece 2 plays a key connecting and supporting role in the whole device. The mounting piece 2 is composed of an L-shaped bottom plate, one end of the L-shaped bottom plate is connected with the coke guide car in a stable mode such as welding and bolt connection, and the connecting mode can ensure that the mounting piece 2 cannot be easily loosened during the operation of the coke guide car, thereby providing a basis for stable installation of subsequent components.
[0028] As shown in Figure 1 , 3 : 3:
[0029] The position limiter 1 is provided with a clamping groove 4 on a side adjacent to the L-shaped bottom plate, the clamping groove 4 is used for placing the other end of the L-shaped bottom plate, so that the position limiter 1 is preliminarily positioned with the mounting piece 2, the position limiter 1 has an accurate installation position on the mounting piece 2, and the position limiter 1 can normally play a role.
[0030] As shown in Figure 2 , 3 : 3:
[0031] Symmetrical connecting rods 5 are connected to the side, away from the position limiter 1, of the L-shaped bottom plate. The transverse limiting rod 6 arranged at the end of the connecting rod 5 is of great significance, which can effectively prevent the clamping groove 4 from falling off the L-shaped bottom plate. Because vibration and shaking will be generated during the actual operation of the coke guide car, if the transverse limiting rod 6 is not arranged, the position limiter 1 can be separated from the mounting piece 2 due to the external force, thereby causing the safety device to fail. The transverse limiting rod 6 is like a “lock” for the position limiter 1, and maintains the stable connection state of the position limiter 1 and the mounting piece 2.
[0032] As shown in Figure 1 , 2 : 3:
[0033] The push rod 7 arranged at the bottom of the connecting rod 5 provides convenience for the maintenance and replacement of the position limiter 1. When the position limiter 1 needs to be disassembled and maintained, the operator can bring the separately arranged connecting rods 5 closer through the push rod 7. In this way, the transverse position limiter 6 is away from the both ends of the clamping groove 4, and the position limiter releases the clamping groove 4. At this time, the operator only needs to lift the position limiter 1 upward, and then the position limiter 1 can be removed from the mounting piece 2, which greatly improves the efficiency of equipment maintenance.
[0034] As shown in Figure 1 , 3 ,
[0035] The sliding groove 8 arranged on the L-shaped bottom plate and the sliding block 9 arranged on the connecting rod 5 cooperate with each other, further optimizing the performance of the device. When the connecting rod 5 is brought closer to the middle through the push rod 7, the sliding block 9 slides in the sliding groove 8, so that the connecting rod 5 can move more smoothly horizontally, effectively preventing the connecting rod 5 from being stuck during movement, and ensuring the smoothness of the operation.
[0036] As shown in Figure 2 , 3 ,
[0037] The spring 10 installed between the adjacent connecting rods 5 and the sliding rod passing through the spring together constitute a reset system. When the connecting rod 5 is displaced by external force, the spring will generate elastic force to promote the connecting rod 5 to return to the initial position. The purpose of this design is to prevent the position limiter 1 from moving upward and falling off, further enhancing the stability and reliability of the safety device.
[0038] Working principle: In the production process of coking industry, the coke barrier car operates. The angle iron is fixed on the equipment adjacent to the coke barrier car. When the coke barrier car approaches the equipment, the angle iron gradually approaches the position limiter 1. Only when the output ends of the two position limiters 1 vertically arranged simultaneously collide with the angle iron and receive the signal, the coke barrier car is allowed to perform the next operation. For example, only when both position limiters 1 detect the angle iron and send normal signals, the dust removal valve of the coke barrier car can normally operate to perform dust removal and other related operations. If only one position limiter 1 sends a signal, the system will determine that the signal is abnormal, preventing the next operation from being performed, thereby effectively preventing the collision and damage of the equipment and the rear-end components caused by the signal error of a single position limiter 1, avoiding the occurrence of production accidents, and ensuring the continuity and stability of the production of the coking enterprise.

For those skilled in the art, the specific meaning of the above terms in the present application can be understood according to the specific circumstances.
[0040] The above is the preferred embodiment of the present application, it should be pointed out that, for those skilled in the art, without departing from the principles described in the present application, a number of improvements and refinements can be made, these improvements and refinements should also be considered as the protection scope of the present application.
