Description

Technical Field

[0001] This utility model relates to a fully enclosed personnel vehicle, specifically a fully enclosed personnel vehicle that combines a monorail hoisting beam and a track, belonging to the field of monorail auxiliary transportation technology. Background Technology

[0002] In the field of underground coal mine auxiliary transportation, single-diesel-engine monorail auxiliary transportation systems are mainly used for transporting materials, equipment, and personnel. The monorail lifting beam can transport both equipment and materials, as well as personnel. This system typically has two load-bearing methods: one is that the equipment runs directly under the track and is pulled by a locomotive via a tie rod; the other is that large materials are transported by suspending them from the lifting beam.

[0003] In existing technologies, such as the fixed-carriage rail and monorail dual-purpose mine car for coal mines disclosed in CN113460857A, the design focuses on preventing deformation of the car body during lifting by using lifting rings and lifting plates. While this solution achieves dual-purpose use for rail transport and lifting beam transport, it targets the mine car body and does not address the need for fully enclosed personnel carriers for safe and comfortable personnel transport. Furthermore, it lacks adaptability to complex roadways in personnel transport scenarios. Currently, in monorail-assisted transport systems, when the monorail locomotive heads to the working face, the demand for material and equipment transport is high. If the lifting beam is entirely used for material transport at this time, the personnel carrier, which can only be suspended below the lifting beam, cannot transport personnel, hindering normal production and reducing efficiency. When personnel return from the working face, materials and... With significantly reduced equipment transportation demands and a smaller system load, the operating speed of the monorail needs to be adjusted to improve system transportation efficiency. If the personnel carrier can only be directly suspended from the rail, the system length cannot be shortened. System length, besides load capacity, is a crucial factor affecting system operating speed, especially in complex underground tunnels with numerous curves and slopes. A longer system will significantly reduce operating speed. Furthermore, traditional personnel carriers are inadequate in terms of comfort and safety. Common designs lack effective vibration damping systems, resulting in severe jolts for occupants when traveling on underground slopes. Additionally, the weak side protection makes it difficult to prevent flying rocks or accidental falls. Moreover, most personnel carriers do not consider compatibility with diesel-powered monorails and lack critical safety accessories such as fixed exhaust hoses, limiting their application scope. Summary of the Invention

[0004] The purpose of this utility model is to provide a monorail lifting beam and a track-mounted fully enclosed personnel vehicle in order to solve at least one of the above-mentioned technical problems.

[0005] This utility model achieves the above-mentioned objective through the following technical solution: a fully enclosed personnel car that can be used for both a single-rail lifting beam and a track, including a fully enclosed personnel car assembly, which has two hanging modes on the single-rail crane: lifting beam hanging and track hanging. The top of the fully enclosed personnel carrier assembly is connected to a traveling trolley, which is suspended below the track of the monorail. The fully enclosed personnel carrier assembly forms a track-suspended mode with the monorail through the traveling trolley. The top of the fully enclosed personnel carrier assembly is also connected to a pin shaft, which is suspended below the lifting beam of the monorail. The fully enclosed personnel carrier assembly forms a lifting beam suspension mode with the monorail through the pin shaft.

[0006] As a further improvement of this utility model, two walking carts are provided, each of which is equipped with a walking wheel and a guide wheel.

[0007] As a further improvement of this utility model: the top of the frame of the fully enclosed vehicle assembly is fixedly connected to a canopy, a reinforcing beam is fixedly connected to the axis of the canopy, and multiple reinforcing ribs are connected to both sides of the reinforcing beam. The traveling trolley is connected to the reinforcing beam through a ball joint, and pins are fixedly connected to both sides of the reinforcing beam.

[0008] As a further improvement of this utility model, a coupling is connected to the front end of the reinforcing beam in the direction of movement of the fully enclosed personnel vehicle assembly.

[0009] As a further improvement of this utility model: the bottom of the frame of the fully enclosed vehicle assembly is fixedly connected to a chassis, and multiple seats are fixedly connected to the chassis.

[0010] As a further improvement of this utility model, the frame of the fully enclosed personnel vehicle assembly is movably connected to sliding doors on both sides.

[0011] As a further improvement of this utility model: the frame of the fully enclosed vehicle assembly includes four swing arms, the upper and lower ends of which are rotatably connected to the four corners of the roof and the chassis, and the swing arms, roof and chassis together form a parallelogram mechanism.

[0012] As a further improvement of this utility model: a shock-absorbing unit is provided at the connection between the swing arm and the chassis, and the shock-absorbing unit includes, but is not limited to, a hydraulic damper or a rubber hinge bushing.

[0013] As a further improvement of this utility model: a hose fixing plate is also fixedly connected to the roof, and the hose of the diesel engine monorail crane is fixedly connected to the hose fixing plate.

[0014] The beneficial effects of this utility model are: This utility model achieves free switching between two modes: direct track suspension and lifting beam suspension by integrating a walking trolley and a top pin shaft. It perfectly solves the contradictory requirements of system grouping and efficiency during different periods of material peak and personnel return in underground transportation, greatly improves the flexibility of transportation scheduling and overall work efficiency, and solves the problems of existing single personnel and vehicle suspension methods, inability to balance transportation efficiency and scheduling flexibility, poor comfort and insufficient safety. This utility model is equipped with a parallelogram mechanism consisting of a roof, a swing arm, and a chassis. Combined with shock absorption units such as hydraulic dampers or rubber hinge bushings at the bottom of the swing arm, it can efficiently filter the impact and vibration caused by uneven tracks, ensuring that the chassis can remain relatively stable when the vehicle passes through underground ramps. It automatically adjusts the chassis posture when passing through ramps, providing excellent stability and comfort for passengers. The fully enclosed sliding doors on both sides of the vehicle body fundamentally solve the problem of weak protection of traditional vehicles and personnel, effectively preventing the dual safety risks of flying rocks in the tunnel and personnel falling during emergency stops. The utility model features a specially designed hose fixing plate on the ceiling, which enables the personnel carrier to be safely and reliably adapted to a diesel engine monorail system, thus expanding its application range.

[0016] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0017] Example 1, as Figures 1 to 4 As shown, a fully enclosed personnel carrier that can be used for both lifting beams and tracks on a monorail crane includes a fully enclosed personnel carrier assembly. The fully enclosed personnel carrier assembly has two lifting modes on the monorail crane: lifting beam suspension and track suspension. The top of the fully enclosed personnel carrier assembly is connected to a traveling trolley 1, which is suspended below the track of the monorail. The fully enclosed personnel carrier assembly forms a track-suspended mode with the monorail through the traveling trolley 1. The top of the fully enclosed personnel carrier assembly is also connected to a pin shaft 8, which is suspended below the lifting beam of the monorail. The fully enclosed personnel carrier assembly forms a lifting beam suspension mode with the monorail through the pin shaft 8.

[0018] By setting up two modes—a track-suspended mode where the trolley 1 is directly suspended from the track and a lifting beam-suspended mode where it is suspended from the lifting beam via pin 8—the vehicle and personnel possess flexible transport adaptability. During peak material transport periods, the track-suspended mode can be used, without occupying lifting beam resources; during personnel return trips, the lifting beam-suspended mode can be used, shortening the system length and increasing operating speed. This systematically resolves the contradiction between transport efficiency and operating speed.

[0019] Example 2: In addition to all the technical features in Example 1, this example also includes: two traveling trolleys 1 are provided, each traveling trolley 1 is equipped with a traveling wheel and a guide wheel. The traveling wheel provides the driving force to move forward along the track, while the guide wheel effectively constrains the lateral position of the trolley relative to the track. The two work together to ensure that the traveling trolley 1 will not derail and can turn smoothly when running in complex underground curves and slopes, which greatly improves the operational reliability and passability in the track-suspended mode.

[0020] The top of the fully enclosed personnel carrier assembly is fixedly connected to a canopy 3. A reinforcing beam is fixedly connected to the axis of the canopy 3, and multiple reinforcing ribs are connected to both sides of the reinforcing beam. The traveling trolley 1 is connected to the reinforcing beam via a ball joint. The pin 8 is fixedly connected to both sides of the reinforcing beam. The traveling trolley 1 is connected to the reinforcing beam of the canopy 3 via a ball joint, which gives the personnel carrier a multi-degree-of-freedom relative swing capability between the canopy 3 and the traveling trolley 1 when suspended on the track, so that it can better adapt to the undulation and inclination of the track. At the same time, the pin 8 used for suspending the lifting beam is directly set on the reinforcing beam, ensuring the structural strength of the suspension point and providing a stable and durable mechanical interface for both suspension modes.

[0021] A coupling 2 is connected to the front end of the reinforcing beam in the direction of movement of the fully enclosed personnel carrier assembly. The coupling 2 located at the front end of the reinforcing beam provides a quick connection point for the personnel carrier to the monorail power system tie rod in the track-suspended mode, so that the traveling trolley 1 can be reliably pulled and integrated into the entire train formation, ensuring that the track-suspended mode can achieve traction.

[0022] In Example 3, in addition to all the technical features in Example 1, this example also includes: a chassis 5 is fixedly connected to the bottom of the frame of the fully enclosed passenger vehicle assembly, and multiple seats 6 are fixedly connected to the chassis 5. The chassis 5 constitutes the main load-bearing frame of the passenger vehicle, providing a stable installation foundation for the multiple seats 6 and other components installed on it, making reasonable use of space, ensuring the number of passengers and the basic stability of the ride, and also creating conditions for the installation of suspension components such as the swing arm 4.

[0023] The fully enclosed personnel carrier assembly has sliding doors 7 movably connected to both sides of the frame. The sliding doors 7 movably connected to both sides of the frame form a fully enclosed protective barrier, which can effectively block the debris that may be splashed in the tunnel and prevent it from causing injury to the crew. It can also prevent the crew from falling out of the car due to inertia when the locomotive suddenly stops, thus improving the passive safety of personnel transportation.

[0024] The frame of the fully enclosed passenger vehicle assembly includes four swing arms 4. The upper and lower ends of the swing arms 4 are rotatably connected to the four corners of the roof 3 and the chassis 5, respectively. The swing arms 4, the roof 3 and the chassis 5 together form a parallelogram mechanism. When passing through a ramp, this parallelogram mechanism enables the chassis 5 to swing adaptively relative to the roof 3 under the action of gravity, rather than rigidly tilting. This maximizes the relative horizontality of the seat 6 bearing surface, reduces the discomfort caused by the tilt of the vehicle body, and greatly improves the riding comfort.

[0025] The connection between the swing arm 4 and the chassis 5 is equipped with a shock absorption unit, which includes, but is not limited to, a hydraulic damper or a rubber hinge bushing. The shock absorption unit absorbs and dissipates high-frequency vibrations and instantaneous impact energy caused by track joints, uneven road surfaces, or starting and braking impacts. It works in conjunction with the parallelogram mechanism, one responsible for large-angle attitude adjustment and the other responsible for micro-vibration filtering, together ensuring the dynamic stability of the chassis 5 and the seat 6.

[0026] A hose fixing plate is also fixedly connected to the canopy 3. The hoses of the diesel engine monorail crane are fixedly connected to the hose fixing plate, providing a path for laying and fixing the exhaust and intake hoses that are essential for the diesel engine monorail crane. The high temperature and harmful exhaust pipes are safely isolated outside the traveling trolley 1 and fixed to prevent the exhaust pipes from shaking, wearing or falling off.

[0027] When priority is needed for material transport, the track-suspended mode is used: the trolley 1, equipped with traveling wheels and guide wheels, suspends the personnel car directly under the monorail. Simultaneously, the coupling 2 on the front reinforcing beam of the personnel car's canopy 3 connects to the system's traction rod, integrating the personnel car into the train formation and moving with the system. This mode does not occupy lifting beam resources. When personnel return and the system speed needs to be increased, the mode switches to lifting beam suspension: the entire personnel car is suspended below the lifting beam via pins 8 fixed to the reinforcing beam of the canopy 3, significantly shortening the train system length and facilitating high-speed operation. Regardless of the mode, the parallelogram mechanism formed by the canopy 3, four swing arms 4, and chassis 5 allows the chassis 5 to adaptively swing relative to the canopy 3 under gravity when traversing ramps, maintaining a relatively horizontal occupant bearing surface. Simultaneously, shock-absorbing units at the connection between the swing arms 4 and chassis 5, such as hydraulic dampers or rubber hinge bushings, further absorb the impact and vibration caused by track unevenness. The sliding doors 7 on both sides of the personnel carrier provide full enclosure protection during operation, preventing flying stones from entering and personnel from falling. In addition, the hose fixing plate on the canopy 3 provides a safe and reliable fixing path for the exhaust hose of the diesel engine monorail, ensuring compatibility with the diesel engine system.
