[0002] The firebrick kiln car is used for transferring firebricks in a firebrick production workshop, and needs to be regularly maintained during use. The existing maintenance method is that the operating personnel uses a jack to lift the two sides of the kiln car loaded with firebricks, and manually controls the jack to release pressure after the maintenance is completed. In this process, because the two jacks on the two sides release pressure at different speeds, the kiln car is unevenly stressed on the two sides, causing the kiln car to tilt and the whole kiln car to quickly drop, and the firebricks on the kiln car will fall, which poses a great safety risk.

[0020] The specific embodiments of the utility model are further explained in detail by comparing the drawings and describing the embodiments, the purpose is to help the technical personnel in the field to have more complete, accurate and deep understanding to the conception and technical scheme of the utility model, and help to implement.

[0021] As Figures 1 to 3 The utility model provides a pit-type refractory brick kiln car maintenance auxiliary equipment, including pit, set up in pit and be used for controlling kiln car to lift lifting device and set up on the ground and be used for guiding kiln car to travel track 1, lifting device sets two, two lifting devices distribute in the opposite sides of track 1, and track 1 is provided with limiting piece 2.

[0022] Specifically, as Figures 1 to 3As shown, the lifting device includes a lifting actuator 3 and a lifting plate 4 mounted on the lifting actuator 3 for contacting the kiln car body. The lifting actuator 3 is a vertically mounted hydraulic cylinder connected to a hydraulic station. At least two lifting actuators 3 are provided. The pit is a rectangular pit set in the ground. Two tracks 1 are fixedly mounted horizontally on the ground, located between the two lifting devices. The tracks 1 span the top opening of the pit, and their length direction is parallel to the length direction of the pit. The length of the pit is greater than the length of the kiln car. The lifting plate 4 is horizontally mounted, and its length direction is parallel to the length direction of the tracks 1. The limiting member 2 is horizontally mounted, and its length direction is perpendicular to the length direction of the tracks 1. The limiting block is located above the two tracks 1 and is fixedly connected to the two tracks 1. The limiting member 2 is used to limit the movement of the kiln car. When the kiln car moves along the tracks 1 to the limiting member 2, the kiln car stops moving. Then, the lifting devices on both sides of track 1 work synchronously. The hydraulic station supplies hydraulic oil to all lifting actuators 3. The lifting actuators 3 push the lifting plate 4 upward. After the lifting plate 4 contacts the kiln car, it continues to push the kiln car upward, realizing the lifting of the kiln car. The kiln car wheels separate from track 1, and then maintenance personnel can carry out maintenance on the kiln car (mainly the wheels). After the maintenance is completed, the lifting devices on both sides of track 1 descend synchronously, lowering the kiln car onto track 1.

[0023] With the above structure, all hydraulic cylinders can work synchronously, which makes the kiln car lifting and lowering stable. During the lifting and lowering process, the kiln car is less likely to tilt, and the refractory bricks on the kiln car are less likely to slide down, which can improve the safety of refractory brick kiln car maintenance.

[0024] like Figure 3 As shown, the lifting device also includes a fixed plate 5 and a reinforcing plate 6. The fixed plate 5 is located at the bottom of the pit, and the lifting actuator 3 is fixedly mounted on the fixed plate 5. The reinforcing plate 6 is fixedly connected to the fixed plate 5 and the cylinder of the lifting actuator 3. The fixed plate 5 is horizontally fixed at the bottom of the pit, and multiple reinforcing plates 6 are provided, all of which are evenly distributed circumferentially around the outer perimeter of the cylinder of the lifting actuator 3. The addition of the reinforcing plates 6 can improve the connection strength between the lifting actuator 3 and the fixed plate 5, further improving the operational reliability of the lifting device.

[0025] like Figure 3As shown in the drawings, the lifting device is provided with two lifting actuators 3, and the two lifting actuators 3 are fixedly connected with two ends of the jacking plate 4, respectively. The jacking plate 4 is used for jacking the kiln car at the middle position of the kiln car body. As preferred, the jacking plate 4 is provided with a cushion block 9, the cushion block 9 is made of rubber, and the cushion block 9 is fixedly arranged on the top surface of the jacking plate 4. The cushion block 9 is used for contacting with the kiln car body, and the jacking plate 4 is made of metal. In this way, the cushion block 9 arranged between the jacking plate 4 and the kiln car can avoid direct impact between the jacking plate 4 and the kiln car body after the jacking plate 4 is lifted, and can reduce the generated noise.

[0026] As shown in the drawings, Figure 1 and Figure 2 As shown in the drawings, a ladder 7 is arranged in the pit, and the operating personnel go back and forth between the pit and the ground through the ladder 7. After the kiln car is lifted, the operating personnel on the ground go down to the pit through the ladder 7.

[0027] As shown in the drawings, Figure 1 and Figure 2 As shown in the drawings, a guardrail 8 is arranged on the ground, and the guardrail 8 is distributed around the opening at the top of the pit. The guardrail 8 is vertically arranged and can provide a certain protection for the operation.

[0028] As preferred, a support beam is arranged below the track 1, the support beam is horizontally arranged, the length direction of the support beam is parallel to the length direction of the track 1, and the two ends of the length direction of the support beam are fixedly connected with two opposite side walls of the pit, respectively. The support beam is fixedly connected with the track 1, and the support beam provides a supporting effect for the track 1, thereby improving the carrying capacity and further improving the safety.

[0029] The above is an exemplary description of the present application in combination with the drawings. Obviously, the specific implementation of the present application is not limited by the above method. As long as various non-essential improvements are made by adopting the method concept and technical scheme of the present application, or the above concept and technical scheme of the present application are directly applied to other occasions without improvement, they are all within the protection scope of the present application.
