Description

Technical Field

[0001] The utility model relates to the technical field of hydraulic flaps, in particular to an explosion-proof hydraulic flap device. Background Art

[0002] With the development of industrialization, hydraulic flaps have been developed rapidly as a fast unloading equipment for trucks due to their high unloading efficiency and strong safety. They are widely used in large-scale operations such as grain, coal, feed, wood chips, construction and chemical industry. However, during the unloading process of hydraulic flaps, a large amount of combustible dust may float in the air. When the dust reaches a certain concentration range, it can be ignited by electric sparks. When the dust catches fire, it burns instantly and releases a large amount of heat energy, causing the temperature of the combustion gas to rise suddenly, and the volume to expand violently, forming a very high expansion pressure. The huge pressure is confined in a small space, and an explosion will occur. After the dust explosion occurs, the oxidation reaction is fast, the energy is released in a short time, and it is extremely destructive. It is easy to produce toxic gases, causing poisoning casualties, and it is also easy to produce secondary or multiple chain explosions. The hot objects produced during the dust explosion can cause serious burns to the human body, which will cause huge economic losses.

[0031] The technical solution of the utility model uses a junction box assembly 3 to isolate and protect the joints in the circuit to prevent excessive circuit contact resistance from being excessively high due to poor contact at the joints, thereby preventing heat and fire from coming into contact with dust and causing explosion; by using a first explosion-proof pipe 512 and a second explosion-proof pipe, the first circuit 511 and the second circuit are both in a closed environment and are not in contact with external dust, thereby ensuring the airtightness and stability of the circuit connection, preventing the first circuit 511 and the second circuit from directly coming into contact with combustible dust suspended in the air and causing explosion when sparks are generated, so that the explosion-proof hydraulic flap device 100 can work in a dusty environment, is durable and reliable, and can ensure the safety and stability of the production process.

The wheel limiting mechanism 4 needs to be connected to the control cabinet 6 through the second line. In order to avoid the joint between the synchronous controller 2 and the first line 511 and the joint between the wheel limiting mechanism 4 and the second line due to poor contact, which causes excessive line contact resistance and heat and fire, thereby touching the dust and causing explosion, the joint between the synchronous controller 2 and the first line 511 is isolated and protected by setting a first junction box 31, and the joint between the wheel limiting mechanism 4 and the second line is isolated and protected by setting a second junction box 32. To facilitate line connection, the first junction box 31 is set close to the synchronous controller 2 and installed on the flap platform 1, and the second junction box 32 is close to the wheel limiting mechanism 4. The second junction box 32 is arranged at the rear end of the first junction box 31, and the second junction box 32 is connected to the first junction box 31 through the third line 531. Therefore, only one line needs to be led out from the second junction box 32 to connect with the control cabinet 6.

[0040] In one embodiment, the flap platform 1 includes a front end and a rear end that are relatively arranged, and the synchronous controller 2, the junction box assembly 3 and the wheel stop limit mechanism 4 are all arranged near the rear end; specifically, the synchronous controller 2 and the wheel stop limit mechanism 4 are spaced apart at the rear end of the flap platform 1. In order to facilitate line connection, the first junction box 31 is arranged near the synchronous controller 2 and installed on the flap platform 1, and the second junction box 32 is arranged near the wheel stop limit mechanism 4, and the second junction box 32 is at the rear end of the first junction box 31. The second junction box 32 is connected to the first junction box 31 through a third line 531. Therefore, only one line needs to be led out from the second junction box 32 to connect with the control cabinet 6. Compared with leading out one line each from the first junction box 31 and the second junction box 32 to connect with the control cabinet 6, long-distance scattered wiring can be avoided, making the line structure simpler. In this embodiment, the second junction box 32 can be installed on the flap platform 1 or in a foundation pit. The utility model does not limit the specific installation position of the second junction box 32.
