By manually driving the handle to rotate, the traction rope is gradually released or retracted, so as to gradually open or retract the walkway.

[0004] However, for the walkway mechanism in the related technology, by driving the handle to rotate, the traction rope is gradually released or retracted, so that the speed of opening or retracting the walkway is slow, thus affecting the maintenance efficiency. Summary of the Utility Model

[0005] In order to improve the problem of the slow speed of opening or retracting the existing walkway, the utility model provides a walkway mechanism for a hybrid power unit and a hybrid power unit that can quickly open or retract the walkway board and improve the maintenance efficiency.

[0006] A first object of the utility model is to provide a walkway railing mechanism for a hybrid power unit, and the following technical scheme is adopted:

[0007] A walkway railing mechanism for a hybrid power unit includes a housing and a walkway assembly arranged on the housing;

[0008] The walkway assembly includes a walkway plate hinged to the housing, a railing hinged to one side of the walkway plate, and an elastic member hinged to the walkway plate at one end. The railing is hinged with a first connecting rod, the first connecting rod is hinged to the housing, the housing is rotatably connected with a driving member, one end of the driving member is connected to the railing, and the end of the elastic member away from the walkway plate is hinged to the housing.

[0009] Through the above technical solution, during maintenance, by driving the driving member, the railing is driven to move, the railing drives the first connecting rod and the walkway plate to rotate, and combined with the weight of the walkway plate, the elastic member is compressed, so that the walkway plate can be conveniently and quickly opened. When the maintenance is completed, the driving member is driven to reset, so that the walkway plate is reset. Through the elastic force of the elastic member, it is more labor-saving to retract the walkway plate. Using the elastic member is beneficial to simplify the design, reduce the space occupied by the equipment, reduce the manufacturing and maintenance costs at the same time, and make the retraction of the walkway plate faster and more convenient, thereby increasing the efficiency of maintenance and repair.

[0010] Preferably, the railing includes a protective frame hinged to the walkway plate and an extension rod arranged on the protective frame. The walkway plate is hinged to the protective frame, and one side of the extension rod away from the protective frame is hinged to the first connecting rod.

[0011] Through the above technical solution, when the worker is on the walkway plate, the protective frame is beneficial to prevent the worker from falling and ensure the safety of the worker working at height. By combining the extension rod, it is ensured to realize the overall connecting rod structure, which is beneficial to reduce the consumables and the overall weight.

[0012] Preferably, a first hinge seat is arranged on the top side of the housing. The first hinge seat includes a closed end and an open end. The closed end is fixedly connected to the housing. The first connecting rod extends into the open end and is hinged to the open end, and the first connecting rod is adapted to the open end.

[0013] Through the above technical solution, the open end is beneficial to limit the rotation of the first connecting rod and prevent the first connecting rod from shaking during rotation, so that the rotation is smoother.

[0014] Preferably, the number of the extension rods is multiple, and the multiple extension rods are arranged and distributed along the length direction of the protective frame. The first connecting rods are arranged corresponding to the number of the extension rods, and the multiple first connecting rods are respectively hinged to the multiple extension rods. Multiple first hinge seats are arranged corresponding to the first connecting rods, and the multiple first connecting rods respectively extend into the open ends of the multiple first hinge seats and are hinged to the first hinge seats.

[0015] Through the above technical solution, the multiple extension rods, the multiple first connecting rods and the multiple first hinge seats act synchronously to open or retract the walkway plate, which is beneficial to make the process of opening or retracting the walkway plate more stable.

[0016] Preferably, the driving member includes a connecting portion fixedly connected to the railing, a connecting rod portion hinged at one end to the connecting portion, and a handle provided on the connecting rod portion. One end of the housing is provided with a swivel base, and a rotating shaft is provided on the swivel base. The rotating shaft passes through the connecting rod portion and is rotatably connected to the connecting rod portion. The handle is away from the connecting portion.

[0017] Through the above technical solution, when driving the extension rod, the worker holds and drives the handle, causing the connecting rod portion to rotate along the rotating shaft, driving the hinge joint between the connecting rod portion and the connecting portion to rotate, driving the connecting portion to move, thereby driving the extension rod to move, and the movement of the extension rod further opens or closes the walkway board, having the effect of simple operation.

[0018] Preferably, one side of the connecting portion is hinged to the connecting rod portion, and the side of the connecting portion hinged to the connecting rod portion is the expanding side. The expanding side of the connecting portion expands from near the connecting rod portion to away from the connecting rod portion. The other side of the connecting portion is connected and extended to the end of the expansion. The other side of the connecting portion is fixedly connected to the extension rod.

[0020] Preferably, the elastic member includes a return spring. The housing is further provided with a second hinge seat. One end of the return spring is hinged to the second hinge seat. An auxiliary block is further provided on the walkway board. One end of the auxiliary block is fixedly connected to the walkway board, and the other end of the auxiliary block is hinged to the end of the return spring away from the second hinge seat.

[0021] Through the above technical solution, using a return spring can provide accurate force and displacement response, with low maintenance cost, which is conducive to making full use of elastic reset. Thus, when the walkway board is in the open state, the worker holds and drives the handle, causing the connecting rod portion to rotate along the rotating shaft. Through the first connecting rod and the railing, the walkway board is driven to rotate and the walkway board is retracted. At the same time, when the return spring is in a compressed state, it has an outward expanding elastic force, and the elastic force of the return spring helps to retract the walkway board, making it more labor-saving to retract the walkway board and making it more quick and convenient to retract the walkway board.

[0022] Preferably, there are multiple second hinge seats, and multiple return springs are provided corresponding to the number of second hinge seats.

Example

[0039] A walkway handrail mechanism for a hybrid power unit, referring to Figure 1 The invention comprises a rectangular room 1 and a walkway assembly arranged on the room 1. The hybrid power unit is arranged in the room 1, and the hybrid power unit is protected by the room 1. An inspection opening is provided on the room 1, and a plurality of inspection openings are provided along the four sides of the room 1, and the inspection openings are all covered with side panels 12.

[0040] Among them, refer to Figure 1 and Figure 2 The walkway assembly is used to support workers in maintenance and overhaul. The walkway assembly is located on one long side of the room body 1. Two walkway assemblies are provided, and the two walkway assemblies are respectively located on two opposite sides of the room body 1. The two walkway assemblies are provided to facilitate workers to inspect from the two long sides of the room body 1, thereby increasing the support area, so that workers can repair from multiple angles, thereby repairing different components of the hybrid power unit. During overhaul, the worker passes through the walkway assembly to reach the required inspection position, opens the side panel 12, and then can carry out overhaul.

[0041] Specifically, refer to Figure 1 and Figure 2 The walkway assembly includes a walkway board 2 hinged to the room body 1, a handrail 3 hinged to the walkway board 2, and an elastic member 4. The walkway board 2 is in the shape of a rectangular plate, and the walkway board 2 is distributed along the length direction of the room body 1. One long side of the walkway board 2 is hinged to one long side of the room body 1, and the hinge between the walkway board 2 and the room body 1 is close to the bottom side of the room body 1. Figure 2, the railing 3 includes a protective frame 31 hinged to the walkway board 2 and an extension rod 32 provided on the protective frame 31. The protective frame 31 is a rectangular frame body, and the protective frame 31 is distributed along the length direction of the housing body 1. The other long side of the walkway board 2 is hinged to a long side of the protective frame 31. The extension rod 32 is in the shape of an inverted L rod. The long side of the L shape of the extension rod 32 is fixedly connected to the protective frame 31. The extension rod 32 is distributed along the width direction of the protective frame 31, close to the end of the protective frame 31, and the extension rod 32 extends out of the protective frame 31. The short side of the L shape of the extension rod 32 is close to the housing body 1.

[0042] Refer to Figure 2 And Figure 3 , a first connecting rod 5 is hinged to the short side of the extension rod 32. The first connecting rod 5 is a long rod. A first hinge seat 7 is provided on the top side of the housing body 1. The cross-section of the first hinge seat 7 is in the shape of a U. The first hinge seat 7 includes a closed end and an open end. The closed end of the U shape of the first hinge seat 7 is fixedly connected to the housing body 1. The first connecting rod 5 far from the extension rod 32 extends into the open end of the U shape of the first hinge seat 7, and the first connecting rod 5 extending into the open end is hinged to the first hinge seat 7 through a hinge shaft. The first connecting rod 5 and the open end are mutually adapted, that is, the first connecting rod 5 abuts against the two opposite side walls at the open end. When opening or closing the walkway board 2, by driving the extension rod 32, the hinged part of the extension rod 32 and the first connecting rod 5 rotates, and the hinged part of the first connecting rod 5 and the first hinge seat 7 rotates, so that the first connecting rod 5 rotates. The open end is beneficial to restricting the rotation of the first connecting rod 5 and preventing the left and right shaking during the rotation of the first connecting rod 5, so that the rotation is smoother. At the same time, the extension rod 32 drives the protective frame 31 to rotate along the hinged part with the walkway board 2, and the walkway board 2 rotates along the hinged part with the housing body 1, so that the walkway board 2 rotates, thereby opening or closing the walkway board 2.

[0043] Refer to Figure 2 And Figure 3 , there are two extension rods 32, and the two extension rods 32 are arranged and distributed along the length direction of the protective frame 31. The two extension rods 32 are respectively close to the two ends of the protective frame 31. The first connecting rod 5 is provided with two according to the number of the extension rods 32, and the two first connecting rods 5 are respectively hinged to the two extension rods 32. Similarly, there are two first hinge seats 7 corresponding to the first connecting rod 5. The two first connecting rods 5 respectively extend into the open ends of the two first hinge seats 7, and the two first connecting rods 5 are respectively hinged to the two first hinge seats 7. The two extension rods 32, the two first connecting rods 5 and the two first hinge seats 7 act synchronously to open or close the walkway board 2, which is beneficial to making the process of opening or closing the walkway board 2 more stable.

[0044] Refer to Figure 2 And Figure 3, when the walkway board 2 is opened or retracted, according to the above hinge relationship, it can be known that by driving one of the extension rods 32, the walkway board 2 can be driven to open or retract. Therefore, a driving member 6 is rotatably connected to one end of the housing 1, and one end of the driving member 6 is fixedly connected to one of the extension rods 32. By the worker driving the driving member 6, the extension rod 32 can be driven to move, so as to conveniently open or retract the railing 3.

[0045] Specifically, referring to Figure 2 and Figure 3 , the driving member 6 includes a connecting portion 61 fixedly connected to the extension rod 32, a connecting rod portion 62 hinged at one end to the connecting portion 61, and a handle 63 provided on the connecting rod portion 62. The cross-section of the connecting portion 61 is L-shaped. The long side of the L-shaped connecting portion 61 is hinged to the connecting rod portion 62. The long side of the connecting portion 61 is expanded, and the long side (also known as the expanded side) of the connecting portion 61 is expanded from near the connecting rod portion 62 to away from the connecting rod portion 62. The short side of the connecting portion 61 is connected and extended to the end of the expansion of the long side. The short side of the connecting portion 61 is fixedly connected to the extension rod 32, so as to increase the area of the fixed connection between the connecting portion 61 and the extension rod 32, making the connection more stable, and further better driving the walkway board 2 to open or retract.

[0046] Referring to Figure 3 , a swivel base 8 is provided at one end of the housing 1. The swivel base 8 is square. A rotating shaft 9 is provided on the side of the swivel base 8 facing away from the housing 1. The rotating shaft 9 is distributed along the length direction of the housing 1. The connecting rod portion 62 is in the shape of a long rod. The rotating shaft 9 passes through the connecting rod portion 62, so that the connecting rod portion 62 is rotatably connected to the rotating shaft 9. The handle 63 is far from the connecting portion 61. The handle 63 is cylindrical. The handle 63 is distributed along the length direction of the housing 1. One end of the handle 63 is connected to the connecting rod portion 62. When driving the extension rod 32, the worker holds and drives the handle 63, so that the connecting rod portion 62 rotates along the rotating shaft 9, drives the hinge joint between the connecting rod portion 62 and the connecting portion 61 to rotate, drives the connecting portion 61 to move, thereby driving the extension rod 32 to move, and the movement of the extension rod 32 further opens or closes the walkway board 2.

[0047] Thus, when the walkway plate 2 is in the open state, the worker holds and drives the handle 63, causing the link portion 62 to rotate along the rotating shaft 9, driving the hinge joint between the link portion 62 and the connecting portion 61 to rotate, driving the connecting portion 61 to move, driving the extension rod 32 to move, and then driving the hinge joint between the extension rod 32 and the first link 5 and the hinge joint between the first link 5 and the first hinge seat 7 to rotate, causing the first link 5 to rotate. At the same time, the extension rod 32 drives the protective frame 31 to rotate along the hinge joint with the walkway plate 2, and the walkway plate 2 rotates along the hinge joint with the housing 1. With the assistance of the elastic member 4, the walkway plate 2 rotates, thereby retracting the walkway plate 2. When the walkway plate 2 is in the retracted state, the link portion 62 is distributed along the height direction of the housing 1, the connecting portion 61 is located above the link portion 62, and the handle 63 is located below the link portion 62. By pushing the handle 63 and combining the weight of the walkway plate 2, the walkway plate 2 can be conveniently and quickly opened, thereby increasing the efficiency of maintenance and repair.

[0048] Specifically, referring to Figure 4 and Figure 5 , the elastic member 4 includes a return spring. The housing 1 is further provided with a second hinge seat 10, and the second hinge seat 10 is arranged at one end of the housing 1. One end of the return spring is hinged to the second hinge seat 10. An auxiliary block 11 is further arranged on the walkway plate 2. The auxiliary block 11 is in the shape of a bent long strip. One end of the auxiliary block 11 is fixedly connected to the walkway plate 2, the other end of the auxiliary block 11 is close to the bottom side of the housing 1, and one end of the auxiliary block 11 close to the bottom side is hinged to the end of the return spring away from the second hinge seat 10. When the walkway plate 2 is opened, the return spring is in a compressed state due to the gravity of the walkway plate 2; when the walkway plate 2 is retracted, the return spring is in a natural state.

[0049] Thus, when the walkway plate 2 is in the open state, the worker holds and drives the handle 63, causing the link portion 62 to rotate along the rotating shaft 9. Through the first link 5 and the railing 3, the walkway plate 2 is driven to rotate and the walkway plate 2 is retracted. At the same time, when the return spring is in a compressed state, it has an outward expanding elastic force, thereby providing an obliquely downward force to the bottom side of the auxiliary block 11. Since the walkway plate 2 is hinged to the housing 1, a reverse force (an obliquely upward force) is obtained on the top side of the auxiliary block 11, which helps the walkway plate 2 to be retracted, making it more labor-saving and quicker and more convenient to retract the walkway plate 2. When the walkway plate 2 is in the retracted state, by pushing the handle 63 and combining the weight of the walkway plate 2, the return spring is compressed, and the walkway plate 2 can be conveniently and quickly opened, thereby increasing the efficiency of maintenance and repair.

[0050] Referring to Figure 4, there are two second hinge seats 10, and the two second hinge seats 10 are correspondingly arranged at both ends of the housing 1 one by one. There are two return springs corresponding to the number of the second hinge seats 10, and the two return springs are correspondingly hinged to the two second hinge seats 10 one by one. There are two auxiliary blocks 11 corresponding to the number of the return springs, and the two return springs are correspondingly hinged to the two auxiliary blocks 11 one by one. Thus, double elastic force is provided to assist in retracting the walkway board 2, making it more labor-saving to retract.

[0051] The implementation principle of this application is as follows: During maintenance, the worker holds and drives the handle 63, causing the connecting rod part 62 to rotate along the rotating shaft 9, driving the rotation of the hinged part between the connecting rod part 62 and the connecting part 61, driving the connecting part 61 to move, driving the extension rod 32 to move, and then driving the rotation of the hinged part between the extension rod 32 and the first connecting rod 5, as well as the rotation of the hinged part between the first connecting rod 5 and the first hinge seat 7, causing the first connecting rod 5 to rotate. At the same time, the extension rod 32 drives the protective frame 31 to rotate along the hinged part with the walkway board 2, and the walkway board 2 rotates along the hinged part with the housing 1. Combining with the weight of the walkway board 2, the return spring is compressed, and the walkway board 2 can be conveniently and quickly opened. Finally, the side plate 12 is opened for maintenance, thereby increasing the efficiency of maintenance and repair.

[0052] When the maintenance is completed, the side plate 12 is closed, and the worker holds and drives the handle 63 to reset, causing the walkway board 2 to reset. Due to the elastic force of the return spring, it is more labor-saving and quicker and more convenient to retract the walkway board 2. Embodiment
