Description

Technical Field

[0001] This utility model relates to the field of engineering machinery technology, and in particular to an escalator structure and engineering machinery. Background Technology

[0002] When the escalator of a hydraulic excavator is retracting upwards, its center of gravity is on the outside, which results in resistance to the hydraulic cylinder. However, when it retracts to 90 degrees or the center of gravity of the escalator moves closer to the inside, the resistance decreases and the speed increases. When the escalator's gravitational acceleration changes from resistance to assistance, the escalator speed increases sharply, causing a violent collision with the escalator. This is a very bad result for the escalator and the customer's experience.

[0003] Current technology has shortcomings: the change in the center of gravity of the escalator leads to an increase in speed, which is very destructive to the stairs. The acceleration at the end of the escalator will cause shaking, which is very bad for the customer experience. Utility Model Content

[0004] The purpose of this utility model is to provide an escalator structure and engineering machinery to solve the problem of excessive speed causing abrupt collisions during escalator retrieval and lowering in the prior art.

[0005] To achieve the above objectives, the present invention provides an escalator structure, including an escalator and a mounting base. The left and right sides of one end of the escalator are hinged to the left and right sides of one end of the mounting base via hinge seats. The left and right sides of one end of the mounting base are respectively provided with upward-extending left and right mounting brackets. Vibration-damping pads and buffer pads are respectively provided on the left and right mounting brackets, located above the hinge seats. When the escalator is retracted upwards, the left and right sides of the escalator engage with the vibration-damping pads and buffer pads for vibration damping and buffering. The left and right sides of one end of the mounting base are respectively provided with vibration-damping and buffering structures located below the hinge seats. When the escalator is lowered downwards, the left and right sides of the escalator engage with the vibration-damping and buffering structures on the left and right sides for vibration damping and buffering.

[0006] Furthermore, when the escalator is retracted upwards to its end, the inner side of the vertical center line of the hinge point of the hinge seat is close to the mounting base, and the center of gravity of the escalator is outside the vertical center line of the hinge point of the hinge seat.

[0007] Furthermore, the top of the right mounting bracket is provided with a first pin hole, and the right edge of the escalator is provided with a pin support. The pin support is provided with a second pin hole. When the escalator is retracted upwards to the end, the pin support moves above the right mounting bracket, and the pin passes downwards through the second pin hole and the first pin hole in sequence, so that the escalator is locked on the right mounting bracket.

[0008] Furthermore, the right mounting bracket is provided with a spring structure on the side near the left mounting bracket. The spring structure is located below the first pin hole. The pin support is provided with a pin retaining plate, which is located above the second pin hole. The pin is provided with a limiting plate, which is located above the second pin hole. When the pin passes through the second pin hole and the first pin hole downwards, the bottom end of the pin abuts against the spring structure. The pin pushes the limiting plate upwards through the elastic force of the spring structure, and the limiting plate engages with the pin retaining plate.

[0009] Furthermore, the spring structure includes a fixed plate, two springs, and a movable plate arranged sequentially from bottom to top. The fixed plate is fixed to the right-side mounting bracket, the two springs are distributed along the front and back, and the movable plate can move up and down and abuts against the bottom end of the pin.

[0010] Furthermore, the vibration damping pad and the buffer pad are respectively disposed on the front side of the left mounting bracket and the right mounting bracket. The left and right sides of the escalator are respectively provided with protruding plates. When the escalator is retracted upwards, the protruding plates on the left and right sides respectively move backwards to cooperate with the vibration damping pad and the buffer pad for vibration damping and buffering.

[0011] Furthermore, the mounting base is a box-shaped structure extending front to back. Two hinged seats are distributed left to right on the upper side of the front end face of the mounting base, and two vibration-damping and buffering structures are distributed left to right on the lower side of the front end face of the mounting base. When the escalator is lowered, the upper left and upper right ends of one end of the escalator are hinged to the two hinged seats, and the lower left and lower right ends of one end of the escalator engage with the vibration-damping and buffering structures on the left and right sides, respectively, for vibration damping and buffering. The escalator extends forward and downward at an angle.

[0012] Furthermore, the vibration damping and buffering structure includes a rubber plate, a pressure plate, and a steel plate. The rubber plate is fixed to the mounting base by the pressure plate. Two holes are opened in the middle of the rubber plate for welding the steel plate to the mounting base. The rubber plate protrudes outward relative to the steel plate so that when the escalator is lowered, the escalator presses on the rubber plate first and then the steel plate.

[0013] Furthermore, a left handrail is installed on the left mounting bracket, and a right handrail is installed on the right mounting bracket. Handrails are provided on both the left and right sides of the escalator. When the escalator is retracted upwards, the handrails on the left and right sides are located inside the left and right handrails, respectively. When the escalator is released downwards, the handrails on the left and right sides are positioned corresponding to the left and right handrails, respectively. A sleeve and mounting bolts are provided at the other end of the mounting base.

[0014] This utility model also provides an engineering machinery, including an engineering machinery body and an escalator structure as described in any of the above technical solutions, wherein the escalator structure is disposed on the engineering machinery body.

[0015] In summary, the technical solution of this utility model has the following beneficial effects: The structure of this utility model is reasonable. (1) By setting up an escalator and a mounting base, the left and right sides of one end of the escalator are respectively hinged to the left and right sides of one end of the mounting base through a hinge seat. The left and right sides of one end of the mounting base are respectively provided with an upwardly extending left mounting bracket and a right mounting bracket. The left and right mounting brackets are respectively provided with vibration damping pads and buffer pads. The vibration damping pads and buffer pads are located above the hinge seat. When the escalator is retracted upward, the left and right sides of the escalator cooperate with the vibration damping pads and buffer pads respectively for vibration damping and buffering. Thus, when the escalator is retracted upward, the escalator rotates upward around the hinge seat, and the left and right sides of the escalator cooperate with the vibration damping pads on the left mounting bracket and the buffer pads on the right mounting bracket respectively for vibration damping and buffering. (2) By setting vibration damping and buffering structures on the left and right sides of one end of the mounting base, and the vibration damping and buffering structures are located below the hinge seat, when the escalator is lowered, the left and right sides of the escalator cooperate with the vibration damping and buffering structures on the left and right sides respectively for vibration damping and buffering. Thus, when the escalator is lowered, it rotates downward around the hinge seat, and the left and right sides of the escalator cooperate with the vibration damping and buffering structures on the left and right sides respectively for vibration damping and buffering. As can be seen from the above analysis, this utility model adds a buffering device when the escalator is rising and falling, which solves the problem of excessive impact when the escalator is rising and falling.

[0019] See Figures 1 to 11This embodiment provides an escalator structure, including an escalator 6 and a mounting base 1. The left and right sides of one end of the escalator 6 are respectively hinged to the left and right sides of one end of the mounting base 1 via hinge seats 16. The left and right sides of one end of the mounting base 1 are respectively provided with an upwardly extending left mounting bracket 7 and a right mounting bracket 11. The left mounting bracket 7 and the right mounting bracket 11 are respectively provided with vibration damping pads 9 and buffer pads 10. The vibration damping pads 9 and buffer pads 10 are located above the hinge seats 16. When the escalator 6 is retracted upwards, the left and right sides of the escalator 6 engage with the vibration damping pads 9 and buffer pads 10 for vibration damping and buffering. The left and right sides of one end of the mounting base 1 are respectively provided with vibration damping and buffering structures. The vibration damping and buffering structures are located below the hinge seats 16. When the escalator 6 is released downwards, the left and right sides of the escalator 6 engage with the vibration damping and buffering structures on the left and right sides for vibration damping and buffering. Function: (1) By setting up the escalator and the mounting base, the left and right sides of one end of the escalator are respectively hinged to the left and right sides of one end of the mounting base through the hinge seat. The left and right sides of one end of the mounting base are respectively provided with upward-extending left mounting bracket and right mounting bracket. The left and right mounting brackets are respectively provided with vibration damping pads and buffer pads. The vibration damping pads and buffer pads are located above the hinge seat. When the escalator is retracted upward, the left and right sides of the escalator cooperate with the vibration damping pads and buffer pads respectively for vibration damping and buffering. Thus, when the escalator is retracted upward, the escalator rotates upward around the hinge seat, and the left and right sides of the escalator cooperate with the vibration damping pads on the left mounting bracket and the buffer pads on the right mounting bracket respectively for vibration damping and buffering. (2) By setting vibration damping and buffering structures on the left and right sides of one end of the mounting base, and the vibration damping and buffering structures are located below the hinge seat, when the escalator is lowered, the left and right sides of the escalator cooperate with the vibration damping and buffering structures on the left and right sides respectively for vibration damping and buffering. Thus, when the escalator is lowered, it rotates downward around the hinge seat, and the left and right sides of the escalator cooperate with the vibration damping and buffering structures on the left and right sides respectively for vibration damping and buffering. As can be seen from the above analysis, this utility model adds a buffering device when the escalator is rising and falling, which solves the problem of excessive impact when the escalator is rising and falling.

[0020] Specifically, when the escalator 6 is retracted upwards to its end, the inner side of the vertical center line 24 of the hinge point of the hinge seat 16 is close to the mounting base 1, and the center of gravity 25 of the escalator 6 is outside the vertical center line 24 of the hinge point of the hinge seat 16. Function: This optimizes the escalator's center of gravity structure. The overall structural shape of the escalator ensures that the center of gravity is outside the vertical center line of the hinge point, thus slowing down the speed and preventing a sudden increase in speed.

[0021] Specifically, the top of the right-side mounting bracket 11 is provided with a first pin hole 17, and the right edge of the escalator 6 is provided with a pin support 5. The pin support 5 is provided with a second pin hole 19. When the escalator 6 is retracted to its end, the pin support 5 moves above the right-side mounting bracket 11, and the pin 4 passes downward through the second pin hole 19 and the first pin hole 17 in sequence, so that the escalator 6 is locked on the right-side mounting bracket 11. Function: The pin support mounted on the top of the escalator structure is used to install the pin so that the escalator is locked on the right-side mounting bracket when it is retracted.

[0022] Specifically, a spring structure 20 is provided on the right mounting bracket 11 near the left mounting bracket 7. The spring structure 20 is located below the first pin hole 17. A pin retainer 18 is provided on the pin support 5, located above the second pin hole 19. A limiting plate 21 is provided on the pin 4, located above the second pin hole 19. When the pin 4 passes through the second pin hole 19 and the first pin hole 17 in sequence, the bottom end of the pin 4 abuts against the spring structure 20. The pin 4 pushes the limiting plate 21 upward through the elastic force of the spring structure 20, and the limiting plate 21 engages with the pin retainer 18. Function: Through the elastic support force of the spring structure, the pin can rotate after insertion, causing the limiting plate 21 above the pin to push against the pin retainer 18 above the pin support, ensuring that the pin does not move around during the movement of the escalator.

[0023] Specifically, the spring structure 20 includes a fixed plate, two springs, and a movable plate arranged sequentially from bottom to top. The fixed plate is fixed to the right-side mounting bracket 11. The two springs are distributed along the front and back. The movable plate can move up and down and abuts against the bottom end of the pin 4. Function: The fixed plate supports the two springs, the two springs support the movable plate upwards, and the movable plate supports the pin 4 upwards.

[0024] Specifically, vibration damping pads 9 and buffer pads 10 are respectively installed on the front sides of the left mounting bracket 7 and the right mounting bracket 11. Protruding plates 22 are provided on both the left and right sides of the escalator 6. When the escalator 6 retracts upwards, the protruding plates 22 on both sides move backwards to cooperate with the vibration damping pads 9 and buffer pads 10 for vibration damping and buffering. Function: The protruding plates 22 facilitate vibration damping and buffering when the escalator 6 retracts upwards.

[0025] Specifically, the mounting base 1 is a box-shaped structure extending front to back. Two hinged seats 16 are distributed horizontally on the upper side of the front face of the mounting base 1, and two vibration damping and buffering structures are distributed horizontally on the lower side of the front face of the mounting base 1. When the escalator 6 is lowered, the upper left and upper right ends of one end of the escalator 6 are hinged to the two hinged seats 16 respectively, and the lower left and lower right ends of one end of the escalator 6 are respectively engaged with the vibration damping and buffering structures on the left and right sides for vibration damping and buffering. The escalator 6 extends forward and downward at an angle. Function: This arrangement provides better support for one end of the mounting base 1 and one end of the escalator 6, making it easier for the escalator 6 to be raised and lowered.

[0026] Specifically, the vibration damping and buffering structure includes a rubber plate 13, a pressure plate 14, and a steel plate 15. The rubber plate 13 is fixed to the mounting base 1 by the pressure plate 14. Two holes are opened in the middle of the rubber plate 13 for welding the steel plate 15 to the mounting base 1. The rubber plate 13 protrudes outward relative to the steel plate 15 so that when the escalator 6 is lowered, the escalator 6 presses on the rubber plate 13 first and then the steel plate 15. Function: By protruding outward relative to the steel plate 15, the rubber plate is pressed first to reduce the impact of descent before the steel plate is pressed, thus preventing the rubber plate from being crushed.

[0027] Specifically, a left handrail 8 is installed on the left mounting bracket 7, and a right handrail 12 is installed on the right mounting bracket 11. Handrails 23 are provided on both the left and right sides of the escalator 6. When the escalator 6 is retracted upwards, the handrails 23 on both sides are located inside the left handrail 8 and the right handrail 12, respectively. When the escalator 6 is extended downwards, the handrails 23 on both sides correspond to the positions of the left handrail 8 and the right handrail 12, respectively. A sleeve 2 and a mounting bolt 3 are provided at the other end of the mounting base 1. Function: The handrails 23, left handrail 8, and right handrail 12 facilitate climbing the escalator; the bolted installation structure of the mounting base ensures greater stability of the escalator.

[0028] This utility model also provides an engineering machinery, including the engineering machinery body and a ladder structure according to any of the above-mentioned technical solutions, the ladder structure being mounted on the engineering machinery body. Application: The ladder structure of this utility model can be applied to engineering machinery such as mining hydraulic large excavators. The upward and downward retraction of the ladder can be driven by a hydraulic cylinder; conventional techniques will not be elaborated here.

[0029] In summary, this utility model provides an escalator structure with buffering and limiting devices. The technical solution adopted is to construct a structure that ensures the center of gravity is on the outside when the escalator is retracted to the end. This escalator structure includes a buffer structure and a locking pin device. Compared with the prior art, this technical solution optimizes the escalator's center of gravity structure, adds a buffer device during escalator ascent and descent, and designs a spring-loaded locking pin structure. This solves the problem of excessive impact during escalator ascent and descent.

[0030] The above description is the preferred embodiment of this utility model. It should be noted that for those skilled in the art, several improvements and modifications can be made without departing from the principle of this utility model, and these improvements and modifications are also considered to be within the protection scope of this utility model.
