Description

Technical Field

[0001] The invention belongs to the technical field of monorail cranes, and in particular relates to an explosion-proof device for a diesel engine monorail crane locomotive. Background Art

[0002] A mining monorail crane is a type of underground transport machinery, primarily used for auxiliary transportation. With the continuous advancement of coal mine modernization, hydraulic monorail cranes are increasingly being used for transporting people and equipment within mines both domestically and internationally. The monorail tracks within mines are made up of many short sections of track connected together. Due to the narrow and long shafts and uneven, curved surfaces within mines, the lifting beam of explosion-proof diesel monorail cranes is located in front of the driver's cab during travel and braking, creating blind spots in the driver's field of vision. This can sometimes prevent the driver from clearly seeing obstacles ahead, leading to collisions. Existing monorail cranes are easily damaged in collisions, and their front windows lack protection, making them susceptible to injury to the driver in the event of a collision. Therefore, it is necessary to improve the explosion-proof performance of monorail cranes. Summary of the Invention

[0003] In view of this, the present invention aims to overcome the defects in the prior art and proposes an explosion-proof device for a diesel monorail crane locomotive.

[0004] To achieve the above object, the technical solution created by the present invention is implemented as follows:

[0005] The camshaft is provided with a plurality of springs for supporting the engine, and the springs are provided with a plurality of springs for supporting the engine, and the plurality of springs are provided with springs for supporting the engine.

[0006] Furthermore, the tilt angle of the rear tilt plate relative to the bearing plate is greater than the tilt angle of the rear inclined plate relative to the bearing plate.

[0007] Furthermore, the upper edge of the rear tilt plate is lower than the lower edge of the monorail crane observation window.

[0008] Furthermore, a column end mounting portion is provided on the side of the piston section facing the bottom of the buffer sleeve, and a cylinder end mounting portion is provided at the bottom of the buffer sleeve corresponding to the column end mounting portion. One end of the buffer spring is sleeved on the column end mounting portion, and the other end is sleeved on the cylinder end mounting portion.

[0009] Furthermore, the load-bearing plate, rear inclined plate and rear tilting plate are an integrally formed structure.

[0010] Furthermore, the upper end of the tilting plate is provided with a flange facing the front of the monorail crane.

[0011] Furthermore, the inner buffer plate and the outer buffer plate are both made of rubber material.

[0012] Furthermore, the thickness of the inner buffer plate is 10-30 mm, and the thickness of the outer buffer plate is 15-50 mm.

[0013] Compared with the prior art, the present invention has the following advantages:

[0014] The present invention has a reasonable structural design. By installing an explosion-proof assembly in front of the monorail crane body, when a collision occurs, the buffer frame contacts the obstacle before the body, and the inner buffer pad, the outer buffer pad and the buffer mechanism connected to the buffer frame play a buffering role at the same time to weaken the impact and vibration. When the impact force is large, as the buffer frame is squeezed to the side of the monorail crane body, the buffer columns of the remaining buffer mechanisms will also support the buffer frame to form a second buffer. At the same time, even if scattered heavy objects splash or hit the load-bearing plate, they will fly to the left and right sides of the monorail crane under the guidance of the inclined surface of the rear tilt plate, avoiding direct impact on the body and effectively improving the explosion-proof safety.

Those skilled in the art can understand the specific meanings of the above terms in the present invention based on specific circumstances.

[0026] The present invention will be described in detail below with reference to the accompanying drawings and in combination with embodiments.

[0027] An explosion-proof device for a diesel engine monorail crane locomotive, such as Figures 1 to 7As shown, it includes a monorail crane 1, and an explosion-proof assembly is installed on the body at the front of the monorail crane. The explosion-proof assembly includes a protective cover 2 and a buffer device installed on the front side of the protective cover; the protective cover includes a load-bearing plate 3, an inner buffer pad is provided between the load-bearing plate and the body, rear inclined plates 4 are provided on the left and right sides of the load-bearing plate, and a rear tilting plate 5 is provided on the upper side of the load-bearing plate; the rear tilting plate is V-shaped as a whole, including a left tilting portion 6 and a right tilting portion 7. The sharp angle formed at the junction of the left and right tilting portions faces the front of the monorail crane. Stones and other objects that splash onto the load-bearing plate will slide out along the left tilting portion or the right tilting portion of the rear tilting plate instead of hitting the cab (observation window), thereby improving safety. The buffer device includes a buffer frame 8 provided on the front side of the load-bearing plate , A plurality of buffer mechanisms 9 are provided between the buffer frame and the load-bearing plate, and an outer buffer pad 10 is provided on the front side of the buffer frame. It should be noted that the "left" and "right" referred to in the present invention can be understood as the left and right sides of the direction of travel of the monorail crane.

[0028] The buffer mechanism includes a buffer sleeve 11 and a buffer column 12 in the buffer sleeve. A buffer spring 13 is provided between the buffer column and the buffer sleeve. A piston section 14 is provided at one end of the buffer column extending into the buffer sleeve. The buffer mechanism corresponding to the middle of the load-bearing plate is connected to the buffer frame. The buffer sleeve of the buffer mechanism (connected to the buffer frame) is detachably mounted on the load-bearing plate through a connecting seat 15, and the free end of its buffer column is connected to the buffer frame. Usually, the connecting seat is fixed to the load-bearing plate by bolts. It should be pointed out that, except for the buffer mechanism corresponding to the middle of the load-bearing plate, a buffer gap is left between the free end of the buffer column of the other buffer mechanisms and the buffer frame.

[0029] When the monorail crane collides with an external object during its movement or braking, the buffer frame contacts the obstacle before the monorail crane body, and the inner buffer pad, outer buffer pad and the buffer mechanism connected to the buffer frame play a buffering role at the same time. Even if the impact force of the collision is large, the buffer frame is moved toward the monorail crane body (cab), then the buffer columns of each buffer mechanism will simultaneously press against the buffer frame during this process, effectively playing a buffering role, forming a secondary buffer, and greatly improving the explosion-proof capability of the monorail crane. Figure 6 As shown, in order to ensure that the buffer rack and the buffer column are subjected to balanced force when in contact, a contact plate 18 may be provided at the end of the buffer column.

[0030] Typically, the tilt angle of the rear tilt plate relative to the load-bearing plate is greater than the tilt angle of the rear tilt plate relative to the load-bearing plate. The upper edge of the rear tilt plate is lower than the lower edge of the monorail crane observation window 20 and does not affect the observation line of sight. To the maximum extent. The load-bearing plate, rear tilt plate, and rear tilt plate are an integrally molded structure. The inner and outer buffer plates are both made of rubber material. The thickness of the inner buffer plate is 10-30 mm, and the thickness of the outer buffer plate is 15-50 mm.

[0031] In an optional embodiment, if Figure 7 As shown, the upper end of the tilt plate is equipped with a flange 19 facing the front of the monorail crane, which prevents heavy objects from sliding along the tilt plate surface toward the monorail crane's observation window, thereby improving safety. A column-end mounting portion 16 is provided on the side of the piston section facing the bottom of the buffer sleeve. A cylinder-end mounting portion 17 is provided at the bottom of the buffer sleeve, corresponding to the column-end mounting portion. The buffer spring fits between the column-end mounting portion and the cylinder-end mounting portion. This structural design ensures the stability of the buffer spring, effectively providing a buffering effect when the buffer column extends and retracts.

[0032] The present invention has a reasonable structural design. By installing an explosion-proof assembly in front of the monorail crane body, when a collision occurs, the buffer frame contacts the obstacle before the body, and the inner buffer pad, the outer buffer pad and the buffer mechanism connected to the buffer frame play a buffering role at the same time to weaken the impact and vibration. When the impact force is large, as the buffer frame is squeezed to the side of the monorail crane body, the buffer columns of the remaining buffer mechanisms will also support the buffer frame to form a second buffer. At the same time, even if scattered heavy objects splash or hit the load-bearing plate, they will fly to the left and right sides of the monorail crane under the guidance of the inclined surface of the rear tilt plate, avoiding direct impact on the body and effectively improving the explosion-proof safety.

[0033] The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. Any modifications, equivalent substitutions, improvements, etc. made within the spirit and principles of the present invention should be included in the scope of protection of the present invention.
